NYU open-sources breast cancer screening model trained on over 200,000 mammography exams Breast cancer is the second leading cancer-related cause of death among women in the U.S. It’s estimated that in 2015, 232,000 women were diagnosed with the disease and approximately 40,000 died from it. And while diagnostic exams like mammography have come into wide practice — in 2014, over 39 million breast cancer screenings were performed in the U.S. alone — they’re not always reliable. About 10 to 15 percent of women who undergo a mammogram are asked to return following an inconclusive analysis. That’s why researchers at New York University are investigating an AI-driven technique that promises much higher precision than today’s tests. In a newly published paper on Arxiv.org (“Deep Neural Networks Improve Radiologists’ Performance in Breast Cancer Screening“), they describe a deep convolutional neural network — a class of machine learning algorithm commonly used in image classification — that notches an area under the ROC curve (AUC) of 0.895 in predicting the presence of a cancerous breast tumor. Moreover, they claim that when averaged with the probability of malignancy predicted by a radiologist from the AI system’s results, the AUC is higher than either method achieves separately. [...] The team began by sourcing a data set comprising 229,426 digital screening mammography exams (1,001,093 images) from 141,473 patients, each of which contained at least four images corresponding to the four views typically used in mammography screenings (right craniocaudal, left craniocaudal, right mediolateral oblique, and left mediolateral oblique). They extracted labels from 5,832 exams with at least one biopsy performed within 120 days of the screening mammogram, and then recruited a team of radiologists — all of whom were provided supporting pathology reports — to indicate where the biopsies were taken “at the pixel level.” Will this new openness to open source heed past lessons? NHSX has listed open source as one of its priorities. For Ewan Davis, there is a keen sense of déjà vu – and a desperate desire for the many lessons of the past to be heeded. Open source seems to be back on the NHS agenda, courtesy of NHSX. The body lists one of its responsibilities as: “Making sure that all source code is open by default so that anyone who wants to write code for the NHS can see what we need.” As a new organisation NHSX has no corporate memory and so I thought it might be helpful to share my observations on what happened last time the NHS got excited about open source. It started when Tim Kelsey (peace be upon him) – then NHS England national director for patients and information – went on a trip to the USA. He saw the open source EHR VistA operating in the US Veterans Administration, decided it would be good for the NHS, and wrote it into Tech Fund 1 like Brighton through a stick of rock. I got involved, working for NHS England with guys from World VistA and OSERA to establish what would be needed to localise VistA for the NHS. We came up with a plan but the cost was more than NHS England was willing to pay. NHS VistA was doomed. Our work did lead to the creation of an open source programme within NHS England, though, which rapidly absorbed and refactored Tim’s next idea: Code4Health. Visikol Releases Open Source 3Screen™ Python Library for Training Convolutional Neural Networks for Use in Digital Pathology Over the last two years, Visikol has leveraged its internal 3Screen™ image analysis software to provide its pharmaceutical Clients with unprecedented insights from their tissues. As a leader in the image analysis space, Visikol not only provides best-in-class services to its Clients, but also periodically makes useful 3Screen™ tools available to the academic community. To help the academic community with more easily adopting neural networks in image analysis, Visikol is launching a Python library to assist with training. Cost Sensitivity Analysis Performed for 3D Printed, Open Source Infant Clubfoot Brace Congential talipes equinovarus (CTEV), perhaps better known as clubfoot, is one of the most common congenital physical deformities, as it occurs at least once every 1,000 births. In countries like the US, CTEV is diagnosed at birth and treated while the patient is still a young child, using a method of weekly manipulation and casting, followed by an Achilles tenotomy. Then a foot abduction orthosis (FAO) is worn until the patient is about four years old so that the deformity will not reoccur. Unfortunately, these types of treatment options are not as readily available, or affordable, in developing countries like East Africa, where clubfoot can occur up to eight times every 1,000 births. Open-source solution: Researchers 3D-print system for optical cardiography Open-source solution for multiparametric optical mapping of the heart's electrical activity An international research team from the George Washington University, U.S., and the Moscow Institute of Physics and Technology, Russia, has developed an open-source solution for multiparametric optical mapping of the heart's electrical activity. The technique involves monitoring multiple parameters at once -- for example, both electrical excitation and the changes in the intracellular calcium concentration. This technique is a useful tool for enhancing our understanding of the mechanisms behind cardiac arrhythmias. The 3D models of the mapping system components and the source code for data analysis are openly available, enabling other research groups to benefit from the new solution.

Programming: Python Stigma, Wing Python IDE 7.0 RC1 and the Nonsensical New (Sponsored) 'Study' From RedMonk

2019-03-24 07:07:13

Deconstructing xkcd.com/1987/ To me, the point of this xkcd comic is for Randall to be self-deprecating and point out how he let the Python situation on his computer get out of hand. Unfortunately people don't always pick up on this and instead decide to point at this picture and say, "see, Python is messed up!" But if you take the time to really look at the comic you will notice that pretty much none if it is directly Python's own fault (not knowing what pip is pointing at is pretty much the only thing you could point at and say is still the Python community's fault). Wing Python IDE 7.0 Release Candidate 1 The first release candidate of Wing Python IDE version 7 is now available through our Early Access Program. This release improves the array and data frame viewer, solves several issues in Python code intelligence, fixes VI mode jj and jk, fixes whole file PEP8 reformatting, and makes about 12 other improvements. Microsoft's TypeScript programming language rising fast, almost makes top 10 [Ed: According to a Microsoft site ("RedMonk uses code repositories hosted on GitHub"), Microsoft is on the rise. Lousy research. Delete GitHub as it helps Microsoft craft propaganda. This kind of thing has been done for years. Anti-GPL FUD, claims that Microsoft is top contributor to FOSS and so on. As if GitHub is the same thing as FOSS. GitHub itself is proprietary. RedMonk itself lists Microsoft as a client. The author of this article habitually bashes Linux (for years) and the site is Microsoft-sponsored (through ads). Fernando Cassia said: "If shell and powershell are "programming languages" I'm an astronaut. It's hard to take any analysis based on raw github categories too seriously. I'm not sure JVM languages with a non-JVM counterpart are counted for instance. Is jruby counted in the same category as Ruby?"] RedMonk uses code repositories hosted on GitHub and discussions on Stack Overflow to rank programming languages. read more

Basic AI Concepts: A* Search Algorithm Artificial intelligence in its core strives to solve problems of enormous combinatorial complexity. Over the years, these problems were boiled down to search problems. A path search problem is a computational problem where you have to find a path from point A to point B. In our case, we'll be mapping search problems to appropriate graphs, where the nodes represent all the possible states we can end up in and the edges representing all the possible paths that we have at our disposal.

Learn Python 3 Web-Bootcamp: Strings and Numbers in Python3 (Part 2)

2019-03-23 11:11:42

In the part one of this series, we showed you how to use variables in Python 3. In this tutorial, we are going to work with Strings and Numbers.Note: Before you start, make sure you run each given code to understand that how things work!StringsString is a data type in programming language, strings in Python are very simple at initial glance but we can use them in many ways.A string is a sequence of letters, numbers or symbols enclosed in single or double quotation marks. String are immutable data type that means we can't change it once defined. Strings does not require to be defined in advance. String defined using double quotation marks:greeting = "Hello There!"String defined using single quotes:hint = 'Using single quotes'Using apostrophe in a string. Well, there are two ways of doing it:saying = "If you can't help yourself then nobody will."The other way of using apostrophe with escape character, if you still want to use single quotes:saying = 'If you can\'t help yourself then nobody will.'Combining and concatenating strings using addition operator, in simple words you can join multiple strings:example_concatenation_string = "First part" + ' and ' + "last part"print("Lap" + 'top')print("Another: " + example_concatenation_string)Multiplying a string, you will find it useful later:example_multiply = "Hey There!"*5Know the length of the string using len function:print(len("Hey There!"))length_of_string = "This is a string."print(len(length_of_string))Strings can be written on multiple lines:quote = """A person who never made a mistake never tried  anything new."""print(quote)Find out if the sub-string is present in a string:quote = "A person who never made a mistake never tried anything new."print("mistake" in quote)print("learning" in "You are learning Python 3.")Special characters in strings:We can do formatting in strings using special characters, for instance we need line break, tabs or other formatting. These formatting can be done in a string using special character called escape.Line break in a string:quote = "Albert Einstien said:\nA person who never made a mistake never tried anything new."print(quote)Tab in a string:print("Languages:\n\tC++\n\tPython\n\tJava\n\tC")Printing a backslash character:print("Languages:\\C++\\Python\\Java\\C")Making string omit the recognition of escape character:print(r"Omitting these escape characters \t and \n.")String formattingConvert numerical values to string using str function:print(str(1))print(str(33.33))print(str(987+11j))Use numbers in a string:print("He is " + str(23) + " years old.")We will see string formatting in more detail in upcoming articles.NumbersNumbers are important data type and used in every program, for example: score in games, represent data, store information in web applications and so on. Numbers without decimal considered as integers in Python.Python also supports the order of operations, let us use multiple operations in one expression.Use of add (+), subtract (-), multiply (*) and divide (/) sign in the Python:print(10+2)print(12-2)print(6*2)print(24/2)Exponents use two multiplication operators in Python:print(2**2)print(3**9)Order of operation in a single expression:print(5-1 * 2)print((5-1) * 2)Floats, you can use floats without worrying about how they will behave:print(0.1 + 0.8)print(1.1 * 2.99)That's all folks for this lesson!

RcppArmadillo 0.9.300.2.0 A new RcppArmadillo release based on a new Armadillo upstream release arrived on CRAN and Debian today. Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 583 other packages on CRAN. William Lachance: New ideas, old buildings Last week, Brendan Colloran announced Iodide, a new take on scientific collaboration and reporting that I’ve been really happy to contribute to over the past year-and-a-bit. I’ve been describing it to people I meet as kind of "glitch meets jupyter " but that doesn’t quite do it justice. I’d recommend reading Brendan’s blog post (and taking a look at our demonstration site) to get the full picture. One question that I’ve heard asked (including on Brendan’s post) is why we chose a rather conventional and old technology (Django) for the server backend. Certainly, Iodide has not been shy about building with relatively new or experimental technologies for other parts (e.g. Python on WebAssembly for the notebooks, React/Redux for the frontend). Why not complete the cycle by using a new-fangled JavaScript web server like, I don’t know, NestJS? And while we’re at it, what’s with iodide’s ridiculous REST API? Don’t you know GraphQL is the only legitimate way to expose your backend to the world in 2019?

Germany Urged To Champion Global Treaty To Ban 'Killer Robots'

2019-03-22 22:50:00

An anonymous reader quotes a report from Reuters: Nobel Peace Prize laureate Jody Williams and other activists warned on Thursday that fully autonomous weapons could be deployed in just 3-4 years and urged Germany to lead an international campaign for a ban on so-called "killer robots." Williams, who won the Nobel in 1997 for leading efforts to ban landmines, told reporters Germany should take bold steps to ensure that humans remained in control of lethal weapons. "You cannot lead from the rear," she said. Critics fear that the increasingly autonomous drones, missile defense systems and tanks made possible by new artificial intelligence could turn rogue in a cyber-attack or as a result of programming errors. German Foreign Minister Heiko Maas called last week for action to ensure human control of lethal weapons, but is pushing a non-binding declaration rather than a global ban, given opposition by the United States, Russia and China. The United Nations and European Union have called for a global ban, but discussions so far have not yielded a clear commitment to conclude a treaty. Activists from over 100 non-governmental groups gathered in Berlin this week to pressure Maas and the German government to take more decisive action after twice endorsing a ban on fully autonomous weapons in their 2013 and 2018 coalition accords.

The Scribus Team is deeply saddened to announce the loss of our friend and colleague Peter Linnell who in the end lost his long battle against cancer. It is no understatement to say that without Peter Scribus wouldn’t be what it is today. It was Peter who spotted the potential of Franz Schmid’s initially humble Python program and, as a pre-press consultant at the time, contacted Franz to make him aware of the necessities of PostScript and PDF support, among other things. Peter also wrote the first version of the Scribus online documentation, which resulted in his nickname “mrdocs” in IRC and elsewhere. Until recently, and despite his detoriating health, Peter continued to be involved in building and releasing new Scribus versions. read more

TypeScript's Quiet, Steady Rise Among Programming Languages

2019-03-22 17:27:00

Microsoft's programming language TypeScript has become one of the most popular languages among developers, at least according to a report published by the analyst firm RedMonk this week. Wired: TypeScript jumped from number 16 to number 12, just behind Apple's programming language Swift in RedMonk's semiannual rankings, which were last published in August. Microsoft unveiled TypeScript in 2012, and while it hasn't grown as quickly as Swift -- which has grown faster than any other language, ever since RedMonk started compiling the rankings in 2011 -- TypeScript's own ascendance is impressive, given the sheer number of available programming languages. More and more applications these days use TypeScript. Google's programming framework Angular, the second most popular tool of its type according to data released last year by the startup NPM, is written in TypeScript. So is Vue, an increasingly popular framework finding a home both among smaller companies and tech giants like Alibaba. But RedMonk doesn't look at how many jobs are available for people skilled in a particular language, nor how many companies actually use the language. Instead, the firm tries to spot trends in developer interest by looking at how many projects on GitHub use certain languages, and how many questions are asked about those languages on the programmer Q&A site Stack Overflow. The idea is to get a sense of where the software development profession is heading. Read more of this story at Slashdot.

Effective HMI interaction and safety attention monitoring using eye tracking technology: DeepGlance Quick Interacting effectively with increasingly widespread and advanced systems is one of the most important challenges of our time. Most modern HMIs are based on mouse, keyboard or touch screen and allow controlling even very complex devices in a simple and intuitive way. However, in certain contexts, the user may be unable to have direct contact with a device, in this case, we are talking about hands-free interactions and often voice commands are used to interact. But controlling a system by voice, however natural, is not effective for all types of operations and in all environments. In fact, every technology has its peculiarities, that’s why the HMI design and the UX are the subject of continuous research and aim to offer increasingly effective and natural interaction methods, also thanks to the combined use of more complementary technologies between them. Seven ways to improve your team’s Python If you’re a manager, then you’re always trying to find ways that’ll help your team do more in less time. That’s why you use Python — because it makes your developers more productive. They can spend more time creating new features, and less time debugging or maintaining existing code. It’s no surprise that so many companies are moving to Python. After you’ve moved to Python, you can still make your team more effective. That is, your organization can become more productive, combining technology and culture to help your developers improve. In such a scenario, everyone wins: Your company becomes more efficient and effective, and your team members are more satisfied. Rust All Hands 2019: Array iterators, Rayon, and more A few weeks ago, I had the pleasure of attending the second annual Rust All Hands meeting, hosted by Mozilla at their Berlin office. The attendees were a mix of volunteers and corporate employees covering the full range of Rust development, including the compiler, language, libraries, docs, tools, operations, and community. Although I’m sure there will be an official summary of the meeting (like last year’s), in this article, I’ll cover a few things I was directly involved in. First, I’ll look at a feature many developers have wanted for a long time… GCC 9 libstdc++ Lands The C++17 Parallel Algorithms Implementation From Intel While the release of GCC 9 (v9.1) is just a few weeks ago, a late addition to this annual compiler collection update is its C++ standard library now having a C++17 parallel algorithms implementation thanks to Intel developers. Intel has been working on contributing their C++17 parallel algorithms library code to both GCC and also to the LLVM project. Intel has been working on this Parallel STL implementation the past few years with a focus on contributing the support to the libc++ and libstdc++ C++ standard libraries. The Parallel STL is a portable implementation of threaded/vectorized execution of standard C++ algorithms, which can equate to a performance win on today's multi-core systems.

PHP and Python Programming Leftovers

2019-03-22 04:01:23

Python for NLP: Vocabulary and Phrase Matching with SpaCy This is the third article in this series of articles on Python for Natural Language Processing. In the previous article, we saw how Python's NLTK and spaCy libraries can be used to perform simple NLP tasks such as tokenization, stemming and lemmatization. We also saw how to perform parts of speech tagging, named entity recognition and noun-parsing. However, all of these operations are performed on individual words. Small history about QA To ensure of the quality of PHP, of no regression is a complex, long and serious work. Thanks to all the actors, developers, QA team and users, this works pretty well. So, if you use PHP in a development environment, it is essential to install the RC versions to detect and report us quickly any problem, so we can react before the finale version. For users of my repository, the RC versions of PHP and various extensions are nearly always available in the testing repositories.

750,000 Medtronic Defibrillators Vulnerable To Hacking

2019-03-22 01:25:00

The Homeland Security Department has issued an alert Thursday describing two types of computer-hacking vulnerabilities in 16 different models of Medtronic implantable defibrillators sold around the world, including some still on the market today. The vulnerability also affects bedside monitors that read data from the devices in patients' homes and in-office programming computers used by doctors. From the report: Medtronic recommends that patients only use bedside monitors obtained from a doctor or from Medtronic directly, and to keep it plugged in so it can receive software updates, and that they maintain "good physical control" over the monitor. Implantable defibrillators are complex, battery-run computers implanted in patients' upper chests to monitor the heart and send electric pulses or high-voltage shocks to prevent sudden cardiac death and treat abnormal heart beats. The vulnerabilities announced Thursday do not affect Medtronic pacemakers. The more serious of the two is a vulnerability that could allow improper access to data sent between a defibrillator and an external device like an at-home monitor. The system doesn't use formal authentication or authorization protections, which means an attacker with short-range access to the device could inject or modify data and change device settings, the advisory says. A second vulnerability allows an attacker to read sensitive data streaming out of the device, which could include the patient's name and past health data stored on their device. The system does not use data encryption, the advisory says. (Deploying encryption in medical devices is tricky because is increases computational complexity and therefore uses the battery faster.) The FDA isn't expected to issue a recall as the vulnerabilities are expected to be patched via a future software update. Read more of this story at Slashdot.

Programming: Learning, Java Development Kit 12, and Python Bits

2019-03-21 15:52:47

How to Be a Tech-Savvy Learn how to write a program: You cannot make anything new in the computer world without programming skills. You can create windows, apps, websites, a desktop application using programming languages. Some programming languages that you can learn in your beginning level of becoming tech-savvy is Java, C, C++, Html, CSS, JAVASCRIPT, PHP, PYTHON. You can enhance your programming skills by sitting home by taking online tutorials. Use a Linux or Unix Operating System: If you want to be a tech- savvy I recommend using Unix operating system because a techy person mostly uses the Unix operating system in the world. Unix operating system is open source anyone can use it, and you can view its code too. So, it will help in enhancing your programming skills and learning about technical skills. JDK 12: The new features in Java 12 The production release of Java Development Kit 12, based on Java SE (Standard Edition) 12, is now available. JDK 12 builds are available from Oracle for Linux, Windows, and MacOS.  [...] Open source builds are provided under the GNU General Public License v2, with Classpath Exception. Commercial builds of JDK 12 from Oracle can be found on the Oracle Technology network under a non-open source license. Python dictionary "addition" and "subtraction" A proposal to add a new dictionary operator for Python has spawned a PEP and two large threads on the python-ideas mailing list. To a certain extent, it is starting to look a bit like the "PEP 572 mess"; there are plenty of opinions on whether the feature should be implemented and how it should be spelled, for example. As yet, there has been no formal decision made on how the new steering council will be handling PEP pronouncements, though a review of open PEPs is the council's "highest priority". This PEP will presumably be added into the process; it is likely too late to be included in Python 3.8 even if it were accepted soon, so there is plenty of time to figure it all out before 3.9 is released sometime in 2021. Debugging and Profiling Python Scripts [Tutorial] Debugging and profiling play an important role in Python development. The debugger helps programmers to analyze the complete code. The debugger sets the breakpoints whereas the profilers run our code and give us the details of the execution time. The profilers will identify the bottlenecks in your programs. In this tutorial, we’ll learn about the pdb  Python debugger, cProfile module, and timeit module to time the execution of Python code. This tutorial is an excerpt from a book written by Ganesh Sanjiv Naik titled Mastering Python Scripting for System Administrators. This book will show you how to leverage Python for tasks ranging from text processing, network administration, building GUI, web-scraping as well as database administration including data analytics & reporting. read more

Security: AccessEnforcer, Windows Ransomware Does Major Damage, Spammers Send Junk Mail to Thousands of Printers, Google Cleanup and More

2019-03-21 15:50:27

VLANs and More Added to AccessEnforcer UTM Firewall AccessEnforcer Version 4.1 also updates firewall's operating system to OpenBSD 6.3. OpenBSD is one of the most secure operating systems in the world. Version 6.3 provides additional mitigations against the Spectre and Meltdown vulnerabilities and also mitigates against return-oriented programming and other memory corruption attacks.  Norwegian aluminium firm slowly recovering from ransomware attack   Norwegian aluminium maker Norsk Hydro says it has made some progress restoring its systems back to normal after being hit by Windows ransomware known as LockerGoGa on Monday evening.   Spammers Send Junk Mail to Thousands of Printers Spam has been with us since the very first days of email, but a Russian marketing agency recently took things a stage further by sending good old-fashioned paper-based junk mail over the internet. The company claims to have advertised a graphic design course for its client Skillbox using a software bot that searched for online printers. It printed a one-page promotion on every device it found, directing them to a website boasting about its exploits. The website for the company's marketing campaign, which I am deliberately not linking to here, explains that "by the 2024", it is "94% likely" that bots will replace accountants, auditors, and financial analysts by the million. Consequently, it says, accountants (or anyone else worried about being replaced by AI) should learn graphic design instead. The stats come from a five-year-old Oxford Martin School report, but that needn't concern us here. What's more interesting is another statistic: 600,000. That’s how many printers the marketing agency claim to have clogged up with advertising, according to this report from Graham Cluley. [...] It wouldn't be the first time that someone had spammed printers online. In December, a hacker calling himself TheHackerGiraffe spammed 50,000 printers promoting popular YouTube celebrity PewDiePie. Other incidents have been much darker. Nazi nerd Andrew Aurenheimer, a.k.a. Weev, sent white supremacist messages to every printer in North America that he could find instead of using Shodan, he used Masscan, which is a mass IP port scanner.  Android clampdown on calls and texts access trashes bunch of apps Android looks a little less open now that Google has begun to enforce draconian new rules on accessing a phone's call and text logs. Developers have been forced to remove features or in some cases change the fundamental nature of the application. One example is BlackBerry's Hub, an email client which also aggregated notifications from a variety of apps and presented them chronologically in a timeline. This application has lost its ability to includes calls and texts in that timeline. Exceptions created by Google don't seem to be honoured, developers complained. One said that an enterprise archiving app – a category specifically exempt from the clampdown – has been broken. Another developer, Miroslav Novosvetsky of MobileSoft, rued that he might have to withdraw his Callistics usage monitor app altogether. The martian packet case in our Neutron floating IP setup A community member opened a bug the other day related to a weird networking behavior in the Cloud VPS service, offered by the Cloud Services team at Wikimedia Foundation. This VPS hosting service is based on Openstack, and we implement the networking bits by means of Neutron. Our current setup is based on Openstack Mitaka (old, I know) and the networking architecture we use is extensively described in our docs. What is interesting today is our floating IP setup, which Neutron uses by means of the Netfilter NAT engine. Neutron creates a couple of NAT rules for each floating IP, to implement both SNAT and DNAT. In our setup, if a VM uses a floating IP, then all its traffic to and from The Internet will use this floating IP. In our case, the floating IP range is made of public IPv4 addresses. read more

Small history about QA - Remi Collet

2019-03-21 15:10:00

Despite I'm mainly a developer, I now use most of my time on doing QA on PHP projects. Here is, around release of versions7.2.17RC1 and 7.3.4RC1 a report which should help to understand this activity.   1. Presentation Usually, tests are done by PHP developers, particularly thanks to travis and then by users who will install the RC version available 2 weeks before a GA version. The PHP project follow a release process (cf README.RELEASE_PROCESS) which gives 2 days between the preparation of a version, the Tuesday on git, and the Thursday its announcement in the mailing lists. These 2 days are especially designed to allow the build of binary packages (mostly by Microsoft and often by me for my repository) and to allow a last QA check which mays allow to discover some late issue. When the new versions were available (on Tuesday afternoon) I start building the packages for my repostiory, givinf more coverage than the current travis configuration: Fedora 27 to 31 RHEL 6, 7 and 8-Beta i386 and x86_64 NTS and ZTS various compiler versions  (GCC 4 to 9) and system library versions I also run the build of the 7.3.4RC1 package in Fedora rawhide to trigger the re-build of all the PHP stack in Koschei, one of the CI tools of the Fedora project. Notice : time to build all the packages for all the targets is about 3h for each version !  (I really need a faster builder).   2. Discoverd issues 2.1. Failed tests with pcre2 version 10.33RC1 Already available in rawhide, this version introduce a change in some error message, making 2 tests to fail. Minor issue, fixed in PHP 7.3+: commit c421d9a. 2.2. Failed tests on 32-bit In fix of bug #76117 the output of var_export have changed, make 2 tests to fail on 32-bit. After confirmation by the autor of the change, tests have been fixed in PHP 7.2+ : commits a467a89 and 5c8d69b. 2.3. Regression Koschei allow to discover very quickly a important regression in the run of the "make test" command. After digging, this regression was introduced in the fix of bug #77609, read the comments on the commit 3ead672. After discussion between the Release managers, it have been choosen to: revert this change to get back to a sane situation to re-run the release process (new tag onr git) The version which wil be announced shortly will not be affected byt this regression.   3. Conclusion To ensure of the quality of PHP, of no regression is a complex, long and serious work. Thanks to all the actors, developers, QA team and users, this works pretty well. So, if you use PHP in a development environment, it is essential to install the RC versions to detect and report us quickly any problem, so we can react before the finale version. For users of my repository, the RC versions of PHP and various extensions are nearly always available in the testing repositories.

Coders' Primal Urge To Kill Inefficiency -- Everywhere

2019-03-21 14:00:00

For software engineers, lack of friction is an aesthetic joy, an emotional high, the ideal existential state. It's what drives them, and what shapes our world. An excerpt from an upcoming book on coding, via Wired: The thrust of Silicon Valley is always to take human activity and shift it into metabolic overdrive. And maybe you've wondered, why the heck is that? Why do techies insist that things should be sped up, torqued, optimized? There's one obvious reason, of course: They do it because of the dictates of the market. Capitalism handsomely rewards anyone who can improve a process and squeeze some margin out. But with software, there's something else going on too. For coders, efficiency is more than just a tool for business. It's an existential state, an emotional driver. Coders might have different backgrounds and political opinions, but nearly every one I've ever met found deep, almost soulful pleasure in taking something inefficient -- even just a little bit slow -- and tightening it up a notch. Removing the friction from a system is an aesthetic joy; coders' eyes blaze when they talk about making something run faster or how they eliminated some bothersome human effort from a process. This passion for efficiency isn't unique to software developers. Engineers and inventors have long been motivated by it. During the early years of industrialization, engineers elevated the automation of everyday tasks to a moral good. The engineer was humanity's "redeemer from despairing drudgery and burdensome labor," as Charles Hermany, an engineer himself, wrote in 1904. [...] Many of today's programmers have their efficiency "aha" moment in their teenage years, when they discover that life is full of blindingly dull repetitive tasks and that computers are really good at doing them. (Math homework, with its dull litany of exercises, was one thing that inspired a number of coders I've talked to.) Larry Wall, who created the Perl programming language, and several coauthors wrote that one of the key virtues of a programmer is "laziness" -- of the variety where your unwillingness to perform rote actions inspires you to do the work to automate them.

“What all of us have to do is to make sure we are using AI in a way that is for the benefit of humanity, not to the detriment of humanity.” — Tim Cook In the world of mimicking human emotions artificially, let's explore how AI can be applied to psychology. Behavior is the data in the field of psychology. While Natural Language Programming helps with classification and sentiment analytics, Neuro-Linguistic Programming can help in identifying and analyzing the patterns in thinking and behaving. It can also provide recommendations for the betterment of humankind.

Upgrading to PHP 7.1.27 – how to fix the GPG error: https://packages.sury.org error. - Ken Guest

2019-03-21 09:22:51

If, like me, you’re still using PHP7.1, then you should upgrade to the most current security release which is 7.1.27 and was released on the 7th of March. Prior to that we were on 7.1.24 and missed out on fixed for a number of CVEs that were addressed in 7.1.26  and 7.1.25 – and fixes for a segmentation fault or two as well. This morning, doing this on Debian Jessie yielded the error: W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://packages.sury.org jessie InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B188E2B695BD4743 This is because Ondřej Surý – who maintains the packages there – had to change over to a new DPA signing key as it was present on a server which got compromised. This means that to install packages from there since the new one was switched to, I needed to download the new key: # wget -O /etc/apt/trusted.gpg.d/php.gpg href="https://packages.sury.org/php/apt.gpg After doing that a quick apt-get update set things straight again and apt-get upgrade could then carry on and move things along to 7.1.27. Realising then that we’d missed out on upgrading to 7.1.27 sooner, I’ve added an additional check to our own product’s status page to determine whether the version of PHP being used is the newest “on-branch” version. It looks something like: /** * Get the current/latest version released on branch x for PHP_VERSION. * * @param string $version Branch/Version to check for. e.g. 7.1 or 7.1.23... * * @return string */ function getLatestPHPReleaseOnBranch($version) {     $v = explode(".", $version);     $branch = "{$v[0]}.{$v[1]}";     $major = $v[0];     if (extension_loaded('curl')) {         $url = "https://secure.php.net/releases/active.php";         $curl = curl_init($url);         // Use browser's user agent string.         $agent = $_SERVER['HTTP_USER_AGENT'];         curl_setopt($curl, CURLOPT_USERAGENT, $agent);         curl_setopt($curl, CURLOPT_FAILONERROR, true);         curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);         curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);         $json = curl_exec($curl);         curl_close($curl);         $decoded = json_decode($json, true);         $version = $decoded[$major][$branch]['version'];         return $version;     } else {         return null;     } } $latestPHP = getLatestPHPReleaseOnBranch(PHP_VERSION); if ($latestPHP !== null) {     $current = PHP_MAJOR_VERSION . "." . PHP_MINOR_VERSION . "." . PHP_RELEASE_VERSION;     $branch = PHP_MAJOR_VERSION . "." . PHP_MINOR_VERSION;     echo "Using most recent on-branch PHP release? ", version_compare($current, $latestPHP, "==") ? "Yes" : "No", " (Latest release is $latestPHP Currently on ", PHP_VERSION , ")"; } Please use this, or something similar, to determine when and if you need to update your PHP install.

Benchmarking JavaScript: Spring Tool Suite, Red Hat Dev Studio, and CodeMix

2019-03-21 09:02:03

When working with JavaScript in Eclipse, whether you’re just editing a few files or working on an advanced front-end application, there are both performance and functional considerations you need to be aware of. Let’s take a couple of Eclipse-based IDEs and put them through their paces with a couple of applications, both without and with CodeMix. We’re going to be using BlurAdmin, an AngularJS-based application, and the Node-based Express framework. If you wonder why we’re choosing an AngularJS application in today’s world of Angular 2+, Vue, and React, it’s because Spring Tool Suite (STS) and Red Hat Developer Studio (RHDS) don’t support these frameworks out of the box. In fact, outside of CodeMix, these frameworks aren’t well supported in Eclipse.

Machine Learning With AWS SageMaker

2019-03-21 08:01:03

Businesses are demanding the use of AI and ML to get more from their existing processes and software applications. However, typical software development teams are not always staffed with data scientists or ML engineers. They have application developers who find hard-to-decipher ML algorithms but lack specialized programming skills. Amazon Web Services offers a service known as SageMaker, which takes out the complexity of machine learning. Why AWS SageMaker SageMaker is a managed service offering from AWS with the intent of simplifying the process of building, training, and deploying machine learning models. Typically, developers have to spend a lot of time and effort during various stages of incorporating machine learning in their applications. They have to first find the right sources to collate the training data and then find the best algorithm as per their need. They will also set up training environments and start training the model mostly through trial and error. And finally, they will deploy the model on production. But the peril does not end here; the team also has to scale and manage the production environment.

Programming: ISO C++ Standards Committee, Rust, Python and Programming Language Rankings

2019-03-21 05:42:53

Trip Report: C++ Standards Meeting in Kona, February 2019 A few weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Kona, Hawaii. This was the first committee meeting in 2019; you can find my reports on 2018’s meetings here (November 2018, San Diego), here (June 2018, Rapperswil), and here (March 2018, Jacksonville). These reports, particularly the San Diego one, provide useful context for this post. This week marked the feature-complete deadline of C++20, so there was a heavy focus on figuring out whether certain large features that hadn’t yet merged into the working draft would make it in. Modules and Coroutines made it; Executors and Networking did not. Attendance at this meeting wasn’t quite at last meeting’s record-breaking level, but it was still quite substantial. We continued the experiment started at the last meeting of running Evolution Incubator (“EWGI”) and Library Evolution Incubator (“LEWGI”) subgroups to pre-filter / provide high-level directional guidance for proposals targeting the Evolution and Library Evolution groups (EWG and LEWG), respectively. Comparing Machine Learning Methods When working with data and modeling, its sometimes hard to determine what model you should use for a particular modeling project. A quick way to find an algorithm that might work better than others is to run through an algorithm comparison loop to see how various models work against your data. In this post, I’ll be comparing machine learning methods using a few different sklearn algorithms.

Using Python to Find Correlation Between Categorical and Continuous Variables

2019-03-21 05:02:02

Before making any machine learning model on a tabular dataset, normally we check whether there is a relation between the independent and target variables. This can be done by measuring the correlation between two variables. In Python, Pandas provides a function, dataframe.corr(), to find the correlation between numeric variables only. In this article, we will see how to find the correlation between categorical and continuous variables.

Programming: mmap. Python and More

2019-03-20 20:53:31

Making the Most of your Memory with mmap Sometimes it seems that we have nearly infinite memory resources, especially compared to the tiny 48K RAM of yesteryear’s 8-bit computers. But today’s complex applications can soak up megabytes before you know it. While it would be great if developers planned their memory management for all applications, thinking through a memory management strategy is crucial for applications with especially RAM intensive features like image/video processing, massive databases, and machine learning. How do you plan a memory management strategy? It’s very dependent on your application and its requirements, but a good start is to work with your operating system instead of against it. That’s where memory mapping comes in. mmap can make your application’s performance better while also improving its memory profile by letting you leverage the same virtual memory paging machinery that the OS itself relies on. Smart use of the memory mapping API (Qt, UNIX, Windows) allows you to transparently handle massive data sets, automatically paging them out of memory as needed – and it’s much better than you’re likely to manage with a roll-your-own memory management scheme. Here’s a real-life use case of how we used mmap to optimize RAM use in QiTissue, a medical image application. This application loads, merges, manipulates, and displays highly detailed microscope images that are up to gigabytes in size. It needs to be efficient or risks running out of memory even on desktops loaded with RAM. Moving Kolla images to Python 3 Python… To use 2.7 or to go for 3.x?

OpenXR from The Khronos Group and Monado from Collabora could unify VR & AR

2019-03-20 10:05:13

Tags: Virtual Reality, Misc, Game DevThe Khronos Group recently announced a provisional specification of OpenXR, a royalty-free open-standard aimed at unifying access to VR and AR (collectively known as XR) devices. Also, Collabora announced Monado, a fully open source OpenXR runtime for Linux. The OpenXR 0.90 provisional release specifies a cross-platform Application Programming Interface (API) enabling XR hardware platform vendors to expose the functionality of their runtime systems. By accessing a common set of objects and functions corresponding to application lifecycle, rendering, tracking, frame timing, and input, which are frustratingly different across existing vendor-specific APIs, software developers can run their applications across multiple XR systems with minimal porting effort—significantly reducing industry fragmentation. That sounds pretty good and anything that can help cut-down developer time to support more platforms, is always a good thing. An open standard is always the better option too of course, since you're not locked into any specific vendor. Click to enlarge. Sounds like OpenXR is already gaining pretty good industry support too with Epic Games, Microsoft, Oculus, HTC, Tobii, Unity and more giving their backing to it. Hopefully this means it really will become a standard that's actually used preventing more fragmentation. Since no one headset has truly taken over just yet, with so many already throwing their support around for OpenXR it's looking pretty good. As for Monado, the open source OpenXR runtime for Linux, this is where it gets a little more exciting for us: But Monado is not just a runtime - beyond an open standard and an open source codebase, we want to build an ecosystem encompassing the various XR actors from the open source community and the XR industry. If you are an XR enthusiast, an open source hacker, a hardware vendor or already a major player in the XR industry, check out Monado and join our effort to make Linux a fully XR enabled platform. You can find the announcement about Monado here and the OpenXR announcement here. Hat tip to Nod.

Shadow Root DOM and Custom HTML Tags Automation Using Selenium

2019-03-20 09:03:51

In this article, we will try to solve a multi-level shadow DOM automation problem using an open source GitHub project that will let you test multi-level shadow DOM elements in your Java Selenium project. We will use Chrome as the main browser for testing this feature since Chrome v53+ fully supports shadow DOM. Now let's talk about how this all started. I was working with a project that works on a workflow automation tool called Frevvo. In one of the improvements, we started using the Google Polymer framework that creates shadow DOM elements. As our automation framework was developed with Java Selenium, we were stuck, as the Selenium tool was not able to find elements under the shadow DOM.

Development on Devices: Aaeon, Nageru on GPUs, CircuitPython Hacking by Keith Packard, Coreboot and More

2019-03-20 07:35:23

Latest UP board combines Whiskey Lake with AI Core X modules Aaeon has posted specs for a Linux-ready “UP Xtreme” SBC with a 15W, 8th Gen Whiskey Lake-U CPU, up to 16GB DDR4 and 128GB eMMC, 2x GbE, 6x USB, SATA, and optional AI Core X modules via M.2 and mini-PCIe. Aaeon’s community-backed UP project, which most recently brought us the Intel Apollo Lake based Up Squared and UP Core Plus SBCs, has announced an UP Xtreme hacker board built around Intel’s 8th Gen Whiskey Lake U-series Core processors. This is likely the fastest open-spec, community-backed SBC around, depending on your definition. When your profiler fools you If you've been following my blog, you'll know about Nageru, my live video mixer, and Futatabi, my instant replay program with slow motion. Nageru and Futatabi both work on the principle that the GPU should be responsible for all the pixel pushing—it's just so much better suited than the CPU—but to do that, the GPU first needs to get at the data. Thus, in Nageru, pushing the data from the video card to the GPU is one of the main CPU drivers. (The CPU also runs the UI, does audio processing, runs an embedded copy of Chromium if needed—we don't have full GPU acceleration there yet—and not the least encodes the finished video with x264 if you don't want to use Quick Sync for that.) It's a simple task; take two pre-generated OpenGL textures (luma and chroma) with an associated PBO, take the frame that the video capture card has DMAed into system RAM, and copy it while splitting luma from chroma. It goes about as fast as memory bandwidth will allow. [...] Seemingly after a little more tuning of freelist sizes and such, it could sustain eight 1080p59.94 MJPEG inputs, or 480 frames per second if you wanted to—at around three cores again. Now the profile was starting to look pretty different, too, so there were more optimization opportunities, resulting in this pull request (helping ~15% of a core). Also, setting up the command buffers for the GPU copy seemingly takes ~10% of a core now, but I couldn't find a good way of improving it. Most of the time now is spent in the original memcpy to NVIDIA buffers, and I don't think I can do much better than that without getting the capture card to peer-to-peer DMA directly into the GPU buffers (which is a premium feature you'll need to buy Quadro cards for, it seems). In any case, my original six-camera case now is a walk in the park (leaving CPU for a high-quality x264 encode), which was the goal of the exercise to begin with. So, lesson learned: Sometimes, you need to look at the absolutes, because the relative times (which is what you usually want) can fool you. Keith Packard: metro-snek When I first mentioned Snek a few months ago, Phillip Torrone from Adafruit pointed me at their Metro M0 board, which uses an Arduino-compatible layout but replaces the ATMega 328P with a SAMD21G18A. This chip is an ARM Cortex M0 part with 256kB of flash and 32kB of RAM. Such space! Even though there is already a usable MicroPython port for this board, called CircuitPython, I figured it would be fun to get Snek running as well. The CircuitPython build nearly fills the chip, so the Circuit Python boards all include an off-chip flash part for storing applications. With Snek, there will be plenty of space inside the chip itself for source code, so one could build a cheaper/smaller version without the extra part.

Requesting a HERE Map Image With HTTP and Golang

2019-03-20 05:02:02

At events, I often get asked about generating map images using server-side technologies, or basically any technology that isn't client facing like JavaScript, Android, and iOS. For example, a common request is around providing criteria for a map to be generated as part of a script, report, or similar. Let me show you how. HERE does have a REST API known as the HERE Map Image API and it is consumed through HTTP requests. This API can generate standard map images or map images that include map objects such as polylines, polygons, or similar. Essentially, if you can produce it with the JavaScript SDK on an interactive map, you can produce it on a map image.

Let's back up and level-set. What is Blazor? Blazor is a single-page app framework for building interactive client-side Web apps with .NET. Blazor uses open web standards without plugins or code transpilation. Blazor works in all modern web browsers, including mobile browsers. You write C# in case of JavaScript, and you can use most of the .NET ecosystem of open source libraries. For the most part, if it's .NET Standard, it'll run in the browser. (Of course if you called a Windows API or a Linux specific API and it didn't exist in the client-side browser S world, it's not gonna work, but you get the idea). The .NET code runs inside the context of WebAssembly. You're running "a .NET" inside your browser on the client-side with no plugins, no Silverlight, Java, Flash, just open web standards. WebAssembly is a compact bytecode format optimized for fast download and maximum execution speed. Here's a great diagram from the Blazor docs. Here's where it could get a little confusing. Blazor is the client-side hosting model for Razor Components. I can write Razor Components. I can host them on the server or host them on the client with Blazor. You may have written Razor in the past in .cshtml files, or more recently in .razor files. You can create and share components using Razor - which is a mix of standard C# and standard HTML, and you can host these Razor Components on either the client or the server. In this diagram from the docs you can see that the Razor Components are running on the Server and SignalR (over Web Sockets, etc) is remoting them and updating the DOM on the client. This doesn't require Web Assembly on the client, the .NET code runs in the .NET Core CLR (Common Language Runtime) and has full compatibility - you can do anything you'd like as you are not longer limited by the browser's sandbox. Per the docs: Razor Components decouples component rendering logic from how UI updates are applied. ASP.NET Core Razor Components in .NET Core 3.0 adds support for hosting Razor Components on the server in an ASP.NET Core app. UI updates are handled over a SignalR connection. Here's the canonical "click a button update some HTML" example. @page "/counter"<h1>Counter</h1><p>Current count: @currentCount</p><button class="btn btn-primary" onclick="@IncrementCount">Click me</button>@functions { int currentCount = 0; void IncrementCount() { currentCount++; }} You can see this running entirely in the browser, with the C# .NET code running on the client side. .NET DLLs (assemblies) are downloaded and executed by the CLR that's been compiled into WASM and running entirely in the context of the browser. Note also that I'm stopped at a BREAKPOINT in C# code, except the code is running in the browser and mapped back into JS/WASM world. But if I host my app on the server as hosted Razor Components, the C# code runs entirely on the Server-side and the client-side DOM is updated over a SignalR link. Here I've clicked the button on the client side and hit the breakpoint on the server-side in Visual Studio. No there's no POST and no POST-back. This isn't WebForms - It's Razor Components. It's a SPA app written in C#, not JavaScript, and I can change the locations of the running logic, while the UI remains always standard HTML and CSS. Looking at how Razor Components and now Phoenix LiveView are offering a new way to manage JavaScript-free stateful server-rendered apps has me realizing it’s the best parts of WebForms where the postback is now a persistent websockets tunnel to the backend and only diffs are sent— Scott Hanselman (@shanselman) March 16, 2019 It's a pretty exciting time on the open web. There's a lot of great work happening in this space and I'm very interesting to see how frameworks like Razor Components/Blazor and Phoenix LiveView change (or don't) how we write apps for the web.

416 Range Not Satisfiable - Evert Pot

2019-03-19 15:00:00

It’s possible for a client to request partial responses from a server. For example, a client might only want the first 5 minutes of a video, or the last 100 lines of a log file. HTTP clients and servers can do this with range requests. For example, this request asks for the first 100 bytes: GET /foo.md HTTP/1.1 Range: bytes=1-100 If a server doesn’t support range requests, it will return 200 OK and returns the entire resource. If it did support range requests, it can use 206 Partial Content and return just what the client asked for. However, if a client requested a range that didn’t make sense, it can use 416 Range Not Satisfiable to indicate this. For example, maybe a file was 1024 bytes, and the client asked for bytes 2000-3000. HTTP/1.1 416 Range Not Satisfiable Content-Range: bytes */1000 References RFC7233, Section 4.4 - 416 Range Not Satisfiable

Jupyter Notebook: Forget CSV, Fetch Data With Python

2019-03-19 13:06:01

If you read a book, article, or blog about machine learning, chances are it will use training data from a CSV file. There's nothing wrong with CSV, but let's think about if it is really practical. Wouldn't it be better to read data directly from the DB? Often, you can't feed business data directly into ML training because it needs pre-processing — changing categorial data, calculating new data features, etc. Data preparation/transformation steps can be done quite easily with SQL while fetching original business data. Another advantage of reading data directly from DB is when data changes, it is easier to automate the ML model re-train process. In this post, I describe how to call the Oracle DB from Jupyter notebook with Python code.

Programming: Tools, Demand, Sandboxed API, OpenMP, Radicle, Python and C

2019-03-19 12:00:04

20 Most Useful Tools for Programmers and Developers Programming can be a very hectic task, especially if you are handling a complex project. Sometimes even small projects can give you a hard time. Have you ever found yourself at the verge of giving up in the middle of a project? There are different programming tools that can simplify the coding process and improve your levels of productivity. Here are the 20 most helpful tools for programmers. 10 Programming Languages That Are In Demand Among Top Hiring Companies Coding continues to be one of the most in-demand skills in the job market. Many professionals are considering getting into the field. Possessing the required skills in coding can open doors to some of the highest-paying jobs. One of the main questions that professionals have before getting started is about finding out which programming language to choose and what steps to take to get into coding. The best way to get started is by first understanding which languages are presently in demand, to make this easy online learning platform Simplilearn says that it has come up with a list of ten programming languages that developers and coding enthusiasts should look out for in 2019 to upskill themselves for a bigger paycheck and to excel at their job roles. Google open-sources project for sandboxing C/C++ libraries on Linux Google has open-sourced today a project for sandboxing C and C++ libraries running on Linux systems. The project's name is the Sandboxed API, a tool that Google has been using internally for its data centers for years. The Sandboxed API is now available on GitHub, together with the documentation needed to help other programmers sandbox their C and C++ libraries and protect them from malicious user input and exploits. For ZDNet users unfamiliar with the term, "sandboxing" refers to running an app or source code inside a "sandbox." What’s new in OpenMP 5.0 A new version of the OpenMP standard, 5.0, was released in November 2018 and brings several new constructs to the users. OpenMP is an API consisting of compiler directives and library routines for high-level parallelism in C, C++, and Fortran programs. The upcoming version of GCC adds support for some parts of this newest version of the standard. This article highlights some of the latest features, changes, and “gotchas” to look for in the OpenMP standard. Radicle – A P2P Stack for Code Collaboration Not too long ago I wrote an article about Codeanywhere, a cross-platform cloud IDE that features code collaboration. I recently came across an experimental project that is bound to change collaboration workflow and it goes by the name of Radicle. Radicle is a free and open-source P2P stack for code collaboration designed to be offline first, cryptographically secure, and programmable. It is written in a similarly-named programming language which is a deterministic Lisp derivative designed for creating P2P software. Radicle aims to transform the code collaboration experience by giving programmers a platform that encourages experimentation as they shape their workflow around specific contexts or projects.

Style Guide for Object Design: Release of the PHP edition - Matthias Noback

2019-03-19 10:30:00

With a foreword by Ross Tuck Today I've released the revised edition of my latest book "Style Guide for Object Design". Over the past few weeks I've fixed many issues, smaller and larger ones. Ross Tuck and Laura Cody have read the manuscript and provided me with excellent feedback, which has helped me a lot to get the book in a better shape. I added many sections, asides, and even an extra chapter, because some topics deserve more detail and background than just a few paragraphs. Oh, and Ross wrote the kindest of forewords to kick off the book. It's available in the free sample of the book. The book will be available at the initial "preview release" price of 20 dollars (with a suggested price of 29 dollars) but only until April 15th. Use this link to apply the discount: https://leanpub.com/object-design/c/PREVIEW_RELEASE. What happens on April 15th? Over the past few weeks I've been talking with some fine people from Manning, publisher of tech books. This resulted in a contract with them. They will republish the "Style Guide for Object Design". There will be an e-book, but also a printed version, which is great. The book currently has code samples in PHP and contains some PHP-specific suggestions, but the Manning edition will have Java code samples, and no programming language or ecosystem-specific advice, hopefully making the book useful and appealing to a larger group of object-oriented programmers. This is an exciting thing for me as a book author, because I may be able to reach more people in this way. I know that some readers prefer to read the PHP version, so that's why the version as it is now will be available until April 15th. From that moment on, you won't be able to buy it anymore. However, if you've bought the e-book from Leanpub, you will be granted access to the Manning Early Access Program (MEAP) for the book, meaning that you will eventually be able to read the Manning/Java edition too. Once this is possible, I'll send out an email to existing readers, and update the Leanpub page with instructions for joining the program. Changelog If you already read (part of) the book, here's a summary of the most important changes, so you can decide if it'll be useful to download and read the new version. The full change log is in the back of the book and it includes linkes to the chapters and sections that have been updated. Foreword Added the foreword by Ross Tuck. The lifecycle of an object Rewrote the explanation about the two types of objects. What really defines these types is how they are related to each other. The first type uses the second type (services versus materials). Creating services Added a subsection: "Keeping together configuration values that belong together", which introduces a way to keep together configuration values that belong together. Added an aside: "What if I need the service and the service I retrieve from it?", which answers a common question that was asked by the technical reviewer. Creating other objects Added a new section: "Don't use custom exception classes for invalid argument exceptions", explaining why you don't usually need custom exception classes for invalid argument exceptions. Added an aside: "Adding more object types also leads to more typing, is that really necessary?", explaining some of the benefits of using object types instead of primitive types, just in case people are wondering if all that extra typing is really necessary. Added another example to the section "Don't inject dependencies, optionally pass them as method arguments", explaining how you could rewrite the currency conversion logic using a simple services. Added a comment about the design trade-offs you have to make in this type of situation. Added an aside about PHP's class-based scoping, explaining how it's possible that a named constructor can manipulate private properties directly. Added a subsection "Optionally use the private constructor to enforce constraints" with an example showing how you can use the private constructor when you have multiple named constructors. Finish the chapter with a new section: "The exception to the rule: Data transfer objects" about Data transfer objects, a type of object with less strict rules, which was not yet discussed in detail. Manipulating objects Added a new introductioTruncated by Planet PHP, read more at the original (another 828 bytes)

markingMode:none Is Official: Boost Android Performance While Avoiding Memory Issues

2019-03-19 09:01:06

The Current State As we know it today, in terms of memory management, NativeScript has been using a special routine in its Android runtime: MarkReachableObjects. Its main purpose is to make sure no Java objects are collected by the garbage collector as long as they are needed by their JavaScript representations (in V8), and vice versa. However, while this mechanism ensures stability, it comes at a price — in some cases, the time for a V8 GC pass can get as high as a second, which leads to blocking the UI thread and hurting the overall performance of the app. Background Introducing markingMode: none Starting with NativeScript 3.2, a new and experimental (at the time) mode for garbage collection was added to the Android runtime — the markingMode: none flag. What it does is turn off the previously mentioned routine and use alternative memory management in the Android runtime. The result is much better app performance. Drawbacks? Yes, though avoidable, some unpredictable errors/crashes may occur during runtime due to premature collection of Java/JavaScript objects.

Displaying an Interactive HERE Map With NativeScript and Angular

2019-03-19 05:02:03

Over the past few months, I've written several pieces of content around developing web applications using Angular that included interactive HERE maps as well as tutorials around using HERE maps in progressive web applications using the Ionic Framework. In both these circumstances, the HERE JavaScript SDK was highlighted because we were essentially building web applications, regardless if they were bundled for mobile or not. What if we wanted to change this and build a native Android or iOS application that made use of a cross-platform framework?

Mozilla: Hiring a Vice President From Facebook, Homepage for the JavaScript Specification and More

2019-03-18 19:17:45

Welcome Lindsey Shepard, VP Product Marketing [Ed: Hiring from Facebook (under criminal investigation for privacy infringement crimes) for VP role. Worst Mozilla hire since it put a Microsoft person -- yes, the company that puts back doors in everything and is most cooperative with the NSA (started PRISM) -- in charge of "security".] Most recently, Lindsey headed up corporate-level marketing for Facebook Inc., including leading product marketing for Facebook’s core products: News Feed, News, Stories, Civic Engagement, Privacy and Safety. Before joining Facebook, Lindsey led marketing at GoldieBlox, a Bay Area start-up focused on bridging the gender gap in STEM. A Homepage for the JavaScript Specification Ecma TC39, the JavaScript Standards Committee, is proud to announce that we have shipped a website for following updates to the JavaScript specification. This is the first part of a two-part project aimed at improving our information distribution and documentation. The website provides links to our most significant documents, as well as a list of proposals that are near completion. Our goal is to help people find the information they need in order to understand the specification and our process. While the website is currently an MVP and very simple, we have plans to expand it. These plans include a set of documentation about how we work. We will experiment with other features as the need arises. The website comes as part of work that began last year to better understand how the community was accessing information about the work around the JavaScript specification. We did a series of in-person interviews, followed by a widely distributed survey to better understand what people struggled with. One of the biggest requests was that we publish and maintain a website that helps people find the information they are looking for. A look at Mozilla's data science tooling, Google's Season of Docs, and more news Mozilla released Iodide, a new tool for publishing data science. Still in very early alpha, Iodide is a tool designed to help scientists write interactive documents. It is similar, but not exactly equivalent to Jupyter Notebooks or R Markdown in RStudio. Brendan Colloran shares all the technical details in a post on the Mozilla Hacks blog.If you want explore Iodide yourself, Mozilla has a demo site available. QMO We are happy to let you know that Friday, March 29th, we are organizing Firefox 67 Beta 6 Testday. We’ll be focusing our testing on: Anti-tracking (Fingerprinting and Cryptominers) and Media playback & support. Check out the detailed instructions via this etherpad. read more

Programming/Development: WadC, Rcpp, Django, Qt 3D, Python

2019-03-18 19:13:30

WadC 3.0 A couple of weeks ago I release version 3.0 of Wad Compiler, a lazy functional programming language and IDE for the construction of Doom maps. 3.0 introduces more flexible randomness with rand; two new test maps (blockmap and bsp) that demonstrate approaches to random dungeon generation; some useful data structures in the library; better Hexen support and a bunch of other improvements. Rcpp 1.0.1: Updates Following up on the 10th anniversary and the 1.0.0. release, we excited to share the news of the first update release 1.0.1 of Rcpp. package turned ten on Monday—and we used to opportunity to mark the current version as 1.0.0! It arrived at CRAN overnight, Windows binaries have already been built and I will follow up shortly with the Debian binary. We had four years of regular bi-monthly release leading up to 1.0.0, and having now taken four months since the big 1.0.0 one. Maybe three (or even just two) releases a year will establish itself a natural cadence. Time will tell. Django 2.2 release candidate 1 released Django 2.2 release candidate 1 is the final opportunity for you to try out the salmagundi of new features before Django 2.2 is released. The release candidate stage marks the string freeze and the call for translators to submit translations. Provided no major bugs are discovered that can't be solved in the next two weeks, Django 2.2 will be released on or around April 1. Any delays will be communicated on the django-developers mailing list thread. Qt 3D Pairs Nicely With Vulkan & NVIDIA RTX To Make A Beautiful Path Tracer Not to be confused with Apple's Quartz graphics layer, a new open-source project called Quartz by developer Michał Siejak is producing stunningly beautiful results while being powered by the Vulkan graphics API, making use of Qt 3D, and NVIDIA RTX support within this path tracer. Michał Siejak open-sourced his "Quartz" project this past week and it's the latest open-source Vulkan project catching our eyes. Quartz is a path tracer designed around NVIDIA RTX (and, yes, does require a NVIDIA GPU) and delivering stunning results as an open-source path tracer that works on Windows and Linux. Beyond that, it offers a JavaScript/ES7-like description language for interacting with this path tracing renderer. The ES7-based description language is based on Qt5's QML.
