Tumbleweed Starts Year with New Plasma, Applications, VIM, curl

2019-01-18 16:31:08

This new year has brought several updated packages to users of openSUSE’s rolling release Tumbleweed. Three snapshots have been released in 2019 so far and among the packages updated in the snapshots are KDE’s Plasma, VIM, RE2, QEMU and curl. The 20190112 snapshot brought a little more than a handful of packages. The new upstream Long-Term-Support version of nodejs10 10.15.0 addressed some timing vulnerabilities, updated a dependency with an upgrade to OpenSSL 1.1.0j and the versional also has a 40-seconds timeout that is now applied to servers receiving HTTP headers. The changelog listed several fixes for the highly configurable text editor with vim 8.1.0687, which should now be able to be built with Ruby 2.6.0 that was released at the end of December. Google’s re2 20190101 offered some performance tweaks and bug fixes. The fast real-time compression algorithm of zstd 1.3.8 has better decompression speed on large files. There was a change in the yast2-firewall package, which arrived in the the 20190110 snapshot, that allows new ‘forward_ports’, ‘rich_rules’ and ‘source_ports’ elements in zone entries with yast2-schema 4.1.0. read more

EVOC on Back Doors (ME) and Newt on an Arduino

2019-01-18 10:14:17

Touch-panel PCs offer a choice of Skylake or Bay Trail chips EVOC’s P15 and P17 panel PCs provide Intel Skylake-U or Bay Trail CPUs with IP66 protected 15- or 17-inch resistive displays, plus 2x to 4x GbE ports, up to 8x USB and 6x COM ports, and HDMI, VGA, mini-PCIe, and SATA. Like EVOC’s 15.6-inch PPC-1561 touch-panel PC from May 2008, EVOC’s fanless P15/P17 touch-panel PCs run on 6th Gen Skylake-U or Bay Trail Celeron J1900 processors. The 15-inch P15 and 17-inch P17 offer 5-wire resistive touch and a “next generation design” with “true flat display surface and narrow bezel,” says China-based EVOC. The front aluminum alloy panel offers IP66 waterproofing, dustproofing, and anti-vibration support, as well as over 7H-mohs hardness to prevent scratches, oil, dust, metal chip, and water mist damage.

Programming: Django, PHP, Polonius and More

Django 2.2 alpha 1 released Django 2.2 alpha 1 is now available. It represents the first stage in the 2.2 release cycle and is an opportunity for you to try out the changes coming in Django 2.2. Django 2.2 has a salmagundi of new features which you can read about in the in-development 2.2 release notes. Eliminating PHP polyfills The Symfony project has recently created a set of pure-PHP polyfills for both PHP extensions and newer language features. It allows developers to add requirements upon those functions or language additions without increasing the system requirements upon end users. For the most part, I think this is a good thing, and valuable to have. We've done similar things inside MediaWiki as well for CDB support, Memcached, and internationalization, just to name a few. But the downside is that on platforms where it is possible to install the missing PHP extensions or upgrade PHP itself, we're shipping empty code. MediaWiki requires both the ctypes and mbstring PHP extensions, and our servers have those, so there's no use in deploying polyfills for those, because they'll never be used. In September, Reedy and I replaced the polyfills with "unpolyfills" that simply provide the correct package, so the polyfill is skipped by composer. That removed about 3,700 lines of code from what we're committing, reviewing, and deploying - a big win. Polonius and region errors Now that NLL has been shipped, I’ve been doing some work revisiting the Polonius project. Polonius is the project that implements the “alias-based formulation” described in my older blogpost. Polonius has come a long way since that post; it’s now quite fast and also experimentally integrated into rustc, where it passes the full test suite. Serious Python released!

Mozilla: Rust 1.32.0, Privacy, UX and Firefox Nightly

2019-01-18 03:35:24

Announcing Rust 1.32.0 The Rust team is happy to announce a new version of Rust, 1.32.0. Rust is a programming language that is empowering everyone to build reliable and efficient software. Rust 1.32 Released With New Debugger Macro, Jemalloc Disabled By Default For fans of Rustlang, it's time to fire up rustup: Rust 1.32 is out today as the latest feature update for this increasingly popular programming language. The Rust 1.32 release brings dbg!() as a new debug macro to print the value of a variable as well as its file/line-number and it works with more than just variables but also commands. Julien Vehent: Maybe don't throw away your VPN just yet... At Mozilla, we've long adopted single sign on, first using SAML, nowadays using OpenID Connect (OIDC). Most of our applications, both public facing and internal, require SSO to protect access to privileged resources. We never trust the network and always require strong authentication. And yet, we continue to maintain VPNs to protect our most sensitive admin panels. "How uncool", I hear you object, "and here we thought you were all about DevOps and shit". And you would be correct, but I'm also pragmatic, and I can't count the number of times we've had authentication bugs that let our red team or security auditors bypass authentication. The truth is, even highly experienced programmers and operators make mistakes and will let a bug disable or fail to protect part of that one super sensitive page you never want to leave open to the internet. And I never blame them because SSO/OAuth/OIDC are massively complex protocols that require huge libraries that fail in weird and unexpected ways. I've never reached the point where I fully trust our SSO, because we find one of those auth bypass every other month. Here's the catch: they never lead to major security incidents because we put all our admin panels behind a good old VPN. Reflections on a co-design workshop Co-design workshops help designers learn first-hand the language of the people who use their products, in addition to their pain points, workflows, and motivations. With co-design methods [1] participants are no longer passive recipients of products. Rather, they are involved in the envisioning and re-imagination of them. Participants show us what they need and want through sketching and design exercises. The purpose of a co-design workshop is not to have a pixel-perfect design to implement, rather it’s to learn more about the people who use or will use the product, and to involve them in generating ideas about what to design. We ran a co-design workshop at Mozilla to inform our product design, and we’d like to share our experience with you. [...] Our UX team was tasked with improving the Firefox browser extension experience. When people create browser extensions, they use a form to submit their creations. They submit their code and all the metadata about the extension (name, description, icon, etc.). The metadata provided in the submission form is used to populate the extension’s product page on Firefox Nightly: These Weeks in Firefox: Issue 51 read more

Creating a custom magic file database - Christian Weiske

2019-01-17 20:35:12

The unix file utility command uses a "magic" database to determine which type of data a file contains, independently of the file's name or extension. Here is how I created a custom magic database for testing purposes: Test files At first I created some files to run the tests on: test.html test.php <?php echo 'foo'; ?> test.23 Test 23 Let's see what the standard magic database detect here: $ file test.* test.23: ASCII text PHP script, ASCII text test.html: html document, ASCII text $ file -i test.* test.23: text/plain; charset=us-ascii text/x-php; charset=us-ascii test.html: text/html; charset=us-ascii Magic database The magic database contains the rules that are used to detect the type. It's a plain text file with a rule on each line. Lines may refer to the previous line, so that rules can be combined. The full documentation is available in the magic man page. Here is my simple file that detects "23" within the first 16 bytes of the file and returns the "text/x-23" MIME type: my-magic 0 search/16 23 File containing "23" !:mime text/x-23 We can already use it: $ file -m my-magic test.23 test.23: File containing "23", ASCII text Compilation If you want to use it many times, you should compile it to a binary file for speed reasons: $ file -C -m my-magic $ file -m my-magic.mgc test.* test.23: File containing "23", ASCII text ASCII text test.html: ASCII text $ file -i -m my-magic.mgc test.* test.23: text/x-23; charset=us-ascii text/plain; charset=us-ascii test.html: text/plain; charset=us-ascii The html and PHP files that have been detected properly earlier are not detected anymore, because my own magic database does not contain the rules of the standard magic file (/usr/share/misc/magic.mgc). You may however pass multiple magic files to use, separated with a : $ file -i -m my-magic.mgc:/usr/share/misc/magic.mgc test.* test.23: text/x-23; charset=us-ascii text/x-php; charset=us-ascii test.html: text/html; charset=us-ascii Programming language detection With this knowledge, I wrote a magic file that detects the programming language in source code files, so that phorkie can automatically choose the correct file extension: MIME_Type_PlainDetect.

Gravel, the 'ultimate off-road experience' is now officially supported on Linux

2019-01-17 17:58:03

Tags: Racing, Humble Store, Steam, Virtual ProgrammingThe second racing game from Milestone has arrived on Linux with Gravel, what they claim is the 'ultimate off-road experience'. Much like the previous port of MXGP3, Milestone once again teamed up with the porting company Virtual Programming to bring it to Linux. More about it: Take a tour around the world to discover the range of extreme and wild environments that will offer you a fully off-road experience. There are four disciplines where you can compete with the most powerful cars. Cross Country: Huge areas with different layouts, perfect for competing in checkpoint races in the most evocative landscapes. Run through a waterfall with the aurora borealis as backdrop or try the right grip in the largest deserts in the world. Wild Rush: The wildest locations where you can compete in lap races. Unique environments with natural obstacles that will force you to race your way through the slopes of a mountain, on paradise islands, and through masses of debris and quarry rocks. Speed Cross: Races set in the most beautiful tracks in the world. Real-world tracks, from Europe to America, where you can show your skills in incredible jumps and chicanes. Stadium: Real and fictional arenas, full of jumps and spectacular layouts! It's worth noting, that on Steam user reviews don't paint a very good picture overall. It's sat on Mixed overall, with the most recent being Mostly Negative. As always, take it with a pinch of salt. We may take a look at it sometime soon, depending on receiving a review key. I've reached out to Milestone, so hopefully we can have a proper look. You can find Gravel on Humble Store (on sale) and Steam.

Some changes for me - Stefan Koopmanschap

2019-01-17 16:00:00

For the past years a lot of my focus has been on the (PHP) community. I've spoken at numerous conferences and usergroups. And although I've been cutting down on the amount of conferences, I've done more usergroups in the past year than in the years before that. In December 2018, I've made a decision to cut down on this a bit more. This has nothing to do with not wanting to speak anymore, but more with an opportunity that has arisen that I want to take. I want to put 110% of my effort into this, which means I have to cut down on other activities that I'm doing. Speaking at usergroups and conferences is one of those things. PHP has been my biggest hobby for the past 20+ years. It is great that I have been able to make it my job as well. Since quite a few years, I've picked up on something I've been interested in for years. I've started doing live radio. My first radio show was on the now discontinued Internet radiostation On Air Radio, after which I've moved on to another Internet radiostation IndieXL. Both times I did everything in my own little radio studio that I had built at home. It was a lot of fun. My interest in radio already began when I was a teen. A Dutch morning show was also broadcasting on TV, so I was "watching radio" every morning. In the 90's, the Dutch radiostation KinkFM introduced me to an incredible amount of alternative music. KinkFM was the best radiostation I could imagine in terms of music, but also in terms of DJ's. People with an incredible passion for and knowledge of music. When the station was stopped by its owner in 2011, I was incredibly sad. 2 years ago one of the original founders of KinkFM saved the brand name from the company that at that time owned the name. While he wasn't planning to restart the station, the response he got was overwhelming, so he started researching his options. I got in touch and over a year ago I started doing a Spotify playlist for them called KLUB KINK. Late last year, the announcement came: A new radiostation focussing on alternative music will be launched. Since FM is something nearly of the past, the name will now be KINK. I have been asked to evolve my Spotify playlist into a podcast, and next to that, present a radioshow. After giving it some thought and looking at my schedule, I have decided to take this opportunity. I love doing radio, and to be able to do it for my all-time favorite radiostation is amazing. Starting on Thursday Januari 31, I will be doing a radioshow every Thursday from 7PM to 9PM. Will I be completely gone from conferences and usergroups? Of course not! But as I mentioed earlier, I really want this to succeed, I want to give it 110% of my effort, and that means making tough choices.

Big O tilde notation

Major Security Breach Discovered Affecting Nearly Half of All Airline Travelers Worldwide According to ELAL, the bug stems from their supplier Amadeus’ ( online booking system, which controls a staggering 44% market share of airlines operating worldwide, including United Airlines, Lufthansa, Air Canada, and many more.

Kubernetes flaw shows API security is no ‘set & forget’ deal When a report surfaced last month detailing a ‘severe vulnerability’ in Kubernetes, the popular, open-source software for managing Linux applications deployed within containers, many of us will have wondered what the deeper implications of this alleged flaw could mean.

A deep dive into the technical feasibility of Bloomberg's controversial "Chinese backdoored servers" story These denials also don't add up: Bloomberg says it sourced its story from multiple (anonymous) sources who had direct knowledge of the incidents and who had been employed in the named organizations while they were unfolding. Bloomberg stood by its reporting, and implied that the idea that all these sources from different organizations would collude to pull off a hoax like this. Faced with the seemingly impossible task of sorting truth from hoax in the presence of contradictory statements from Big Tech and Bloomberg, technical experts began trying to evaluate whether the hacks attributed to the Chinese spy agencies were even possible: at first, these analyses were cautiously skeptical, but then they grew more unequivocal.

In this article, you’ll see how to convert an array-like object like NodeList to a real Array using different methods. Array-Like Objects Some objects in JavaScript look like an array, but they aren’t one. That usually means that they have indexed access and a length property, but none of the array methods. Examples include the special variable arguments, DOM node lists, and strings. - Axel Rauschmayer on array-like objects.

Programming: Python 'Standard', and Wing Python IDE 6.1.4

2019-01-17 09:45:37

What should be in the Python standard library? Python has always touted itself as a "batteries included" language; its standard library contains lots of useful modules, often more than enough to solve many types of problems quickly. From time to time, though, some have started to rethink that philosophy, to reduce or restructure the standard library, for a variety of reasons. A discussion at the end of November on the python-dev mailing list revived that debate to some extent. Jonathan Underwood raised the issue, likely unknowingly, when he asked about possibly adding some LZ4 compression library bindings to the standard library. As the project page indicates, it fits in well with the other compression modules already in the standard library. Responses were generally favorable or neutral, though some, like Brett Cannon, wondered if it made sense to broaden the scope a bit to create something similar to hashlib but for compression algorithms. A new free-software forge: Many projects have adopted the "GitHub style" of development over the last few years, though, of course, there are some high-profile exceptions that still use patches and mailing lists. Many projects are leery of putting all of their project metadata into a proprietary service, with limited means of usefully retrieving it should that be necessary, which is why GitLab (which is at least "open core") has been gaining some traction. A recently announced effort looks to kind of bridge the gap; Drew DeVault's ("the hacker's forge") combines elements of both styles of development in a "100% free and open source software forge". It looks to be an ambitious project, but it may also suffer from a lack of "social network" effects, which is part of what sustains GitHub as the forge of choice today, it seems. The announcement blog post is replete with superlatives about, which is "pronounced 'sir hat', or any other way you want", but it is a bit unclear whether the project quite lives up to all of that. It combines many of the features seen at sites like GitHub and GitLab—Git hosting, bug tracking, continuous integration (CI), mailing list management, wikis—but does so in a way that "embraces and improves upon the email-based workflow favored by git itself, along with many of the more hacker-oriented projects around the net". The intent is that each of the separate services integrate well with both and with the external ecosystem so that projects can use it piecemeal. There are two sides to the coin at this point; interested users can either host their own instance or use the hosted version. For now, the hosted version is free to use, since it is still "alpha", but eventually one will need to sign up for a plan, which range from $2 to $10 per month, to stay on the hosted service. There are instructions for getting to run on other servers; it uses nginx, PostgreSQL, Redis, and Python 3 along with a mail server and a cron daemon. Wing Python IDE 6.1.4 This minor release fixes using typing.IO and similar classes as type hints, improves handling of editor splits in goto-definition, fixes failure to install the remote agent, and fixes failure to convert EOLs in the editor.

Rust bindings for GStreamerGL: Memoirs Rust is a great programming language but the community around it’s just amazing. Those are the ingredients for the craft of useful software tools, just like Servo, an experimental browser engine designed for tasks isolation and high parallelization. Both projects, Rust and Servo, are funded by ">">Mozilla. Thanks to Mozilla and Igalia I have the opportunity to work on Servo, adding it HTML5 multimedia features. First, with the help of Fernando Jiménez, we finished what my colleague Philippe Normand and Sebastian Dröge (one of my programming heroes) started: a media player in Rust designed to be integrated in Servo. This media player lives in its own crate: servo/media along with the WebAudio engine. A crate, in Rust jargon, is like a library. This crate is (very ad-hocly) designed to be multimedia framework agnostic, but the only backend right now is for GStreamer. Later we integrated it into Servo adding an initial support for audio and video tags. Currently, servo/media passes, through a IPC channel, the array with the whole frame to render in Servo. This implies, at least, one copy of the frame in memory, and we would like to avoid it. For painting and compositing the web content, Servo uses WebRender, a crate designed to use the GPU intensively. Thus, if instead of raw frame data we pass OpenGL textures to WebRender the performance could be enhanced notoriously. proc-macro-rules Analyzing Robinhood trade history read more

Programming: Flask, Agile, Rust and Python

2019-01-16 23:43:18

How to build an API for a machine learning model in 5 minutes using Flask As a data scientist consultant, I want to make impact with my machine learning models. However, this is easier said than done. When starting a new project, it starts with playing around with the data in a Jupyter notebook. Once you’ve got a full understanding of what data you’re dealing with and have aligned with the client on what steps to take, one of the outcomes can be to create a predictive model. You get excited and go back to your notebook to make the best model possible. The model and the results are presented and everyone is happy. The client wants to run the model in their infrastructure to test if they can really create the expected impact. Also, when people can use the model, you get the input necessary to improve it step by step. But how can we quickly do this, given that the client has some complicated infrastructure that you might not be familiar with? What is Small Scale Scrum? Agile is fast becoming a mainstream way industries act, behave, and work as they look to improve efficiency, minimize costs, and empower staff. Most software developers naturally think, act, and work this way, and alignment towards agile software methodologies has gathered pace in recent years. VersionOne’s 2018 State of Agile report shows that scrum and its variants remain the most popular implementation of agile. This is in part due to changes made to the Scrum Guide’s wording in recent years that make it more amenable to non-software industries. This Week in Rust 269 Async IO in Python: A Complete Walkthrough Async IO is a concurrent programming design that has received dedicated support in Python, evolving rapidly from Python 3.4 through 3.7, and probably beyond.

Finland's Ambitious Plan To Teach Anyone the Basics of AI

2019-01-16 16:50:00

In the era of AI superpowers, Finland is no match for the US and China. So the Scandinavian country is taking a different tack. From a report: It has embarked on an ambitious challenge to teach the basics of AI to 1% of its population, or 55,000 people. Once it reaches that goal, it plans to go further, increasing the share of the population with AI know-how. The scheme is all part of a greater effort to establish Finland as a leader in applying and using the technology. Citizens take an online course that is specifically designed for non-technology experts with no programming experience. The government is now rolling it out nationally. As of mid-December, more than 10,500 people, including at least 4,000 outside of Finland's borders, had graduated from the course. More than 250 companies have also pledged to train part or all of their workforce. Read more of this story at Slashdot.

Programming: Go, JavaScript, Data Science Programming Languages and PyFilesystem

2019-01-16 10:46:38

How To Learn Go Programming Language First appeared in November 2009, Go is a statically typed, compiled programming language designed at Google. You might have just heard about this programming language in the past couple of years but recently, Go has started to gain significant popularity in the coding world. Being light-weight, open source, and suited for today’s microservices architectures, Go is an amazing choice for a language. Also known as Google’s Golang, this language was developed by some of the brilliant minds from Google who created the C programming language. Today, it is one of the fastest growing languages and it’s absolutely a great time to start learning and working with GO. Review: The 6 best JavaScript IDEs Back in the ancient days when Java Swing was new and exciting, I enjoyed using Eclipse for Java development, but soon moved on to other Java IDEs. Five-plus years ago, when I did some Android development with Eclipse, I found the experience OK, but poky. When I tried to use Eclipse Luna with JSDT for JavaScript development in 2014, it constantly displayed false-positive errors for valid code that passed JSHint. A Complete List of The Best Data Science Programming Languages Data science is one of the fastest-growing fields in America. Organizations are employing data scientists at a rapid rate to help them analyze increasingly large and complex data volumes. The proliferation of big data and the need to make sense of it all has created a vortex where all of these things exist together. As a result, new techniques, technologies and theories are continually being developed to run advanced analysis, and they all require development and programming to ensure a path forward. PyFilesystem is greater than or equal to Pathlib I was reading a post by Trey Hunner on why pathlib is great, where he makes the case that pathlib is a better choice than the standard library alternatives that preceded it. I wouldn't actually disagree with a word of it. He's entirely correct. You should probably be using pathlib were it fits. read more

Samba 4.10 RC1 Released: Adds Offline Domain Backups, Now Defaults To Python 3 Samba 4.10 release candidate 1 was announced today as the open-source SMB implementation with support for Windows Server and Active Directory domains. The Samba 4.10 release is bringing export/restore features for Group Policy Objects (GPO), pre-fork process model improvements, support for offline domain backups with the samba-tool domain backup command now supporting an offline option, support for group membership statistics within a domain, Python 3 is now considered the default Python implementation while Python 2 support is retained, JSON logging improvements, and other work. newt-lola Bison and Flex (or any of the yacc/lex family members) are a quick way to generate reliable parsers and lexers for language development. It's easy to write a token recognizer in Flex and a grammar in Bison, and you can readily hook code up to the resulting parsing operation. However, neither Bison nor Flex are really designed for embedded systems where memory is limited and malloc is to be avoided. When starting Newt, I didn't hesitate to use them though; it's was nice to use well tested and debugged tools so that I could focus on other parts of the implementation. With the rest of Newt working well, I decided to go take another look at the cost of lexing and parsing to see if I could reduce their impact on the system.

The 7 Best Practices for Visual Testing With the Galen Framework

2019-01-16 06:04:02

For the past few months, we have been executing our visual testing with the Galen framework. First of all, this should illustrate that we think it is a great framework. For those of you new to the Galen Framework, it is a test framework used for responsive and cross-browser visual testing and functional testing. Galen also has Galen Specs, its own visual testing language. These are based on the Selenium WebDriver. Galen Specs also contains a JavaScript API that allows you to interact directly with Selenium. These features allow users to run tests in any browser in the cloud and in addition test on real mobile devices as well with Appium Studio.

Installing the .NET Core 2.x SDK on a Raspberry Pi and Blinking an LED with System.Device.Gpio

2019-01-16 02:00:00

I've written about running .NET Core on Raspberry Pis before, although support was initially limited. Now that Linux ARM32 is a supported distro, what else can we do? We can certainly quickly and easily install Docker on a Raspberry Pi and be running C# and .NET Core programs in minutes. We can run .NET Core in a stack of Raspberry Pis as a Kubernetes Cluster, making our own tiny cloud and install a serverless platform in it like OpenFaas! If you have a Raspberry Pi 3 with Raspbian on it like I do, check out and note that last part of the URL. You can ask for /2.1, /2.0, etc, just in case you're reading this post in the future, like tomorrow. ;) Everything is always at so you can tell what's Current and what's not. For example, if I end up here I can grab the exact blob URL from the "try again" link and then wget it on my Raspberry Pi. You'll want to get a few prerequisites first. Note these blob links change when new stuff comes out, so you'll want to double check to get latest.sudo apt-get install curl libunwind8 gettextwget I got the Linux ARM 32-bit SDK as well as the ASP.NET Runtime so I have those packages available for any web apps I choose to make. Then we'll extract. You can set it up as a user off of $HOME or in /opt/dotnet and then link to /usr/local/bin.mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-2.2.102-linux-arm.tar.gz -C $HOME/dotnetexport DOTNET_ROOT=$HOME/dotnet export PATH=$PATH:$HOME/dotnet Don't forget to untar the ASP.NET Runtime as well.tar zxf aspnetcore-runtime-2.2.1-linux-arm.tar.gz -C $HOME/dotnet Cool. You will want to add the PATH to your profile if you want it to survive restarts. Then run "dotnet --info" to see if it works.pi@crowpi:~ $ dotnet --info.NET Core SDK (reflecting any global.json): Version: 2.2.102Runtime Environment: OS Name: raspbian OS Version: 9 OS Platform: Linux RID: linux-arm Base Path: /home/pi/dotnet/sdk/2.2.102/Host (useful for support): Version: 2.2.1.NET Core SDKs installed: 2.2.102 [/home/pi/dotnet/sdk].NET Core runtimes installed: Microsoft.AspNetCore.All 2.2.1 [/home/pi/dotnet/shared/Microsoft.AspNetCore.All] Microsoft.AspNetCore.App 2.2.1 [/home/pi/dotnet/shared/Microsoft.AspNetCore.App] Microsoft.NETCore.App 2.2.1 [/home/pi/dotnet/shared/Microsoft.NETCore.App] Looks good. At this point I have BOTH the .NET Core runtime (for running stuff) as well as all the ASP.NET runtime for web apps or little microservices AND the .NET SDK which means I can actually compile code (slowly) on the Pi itself. It's up to me/you. If you aren't ever going to develop (compile code) on the Raspberry Pi, you can just install the runtime, but I think it's nice to be prepared. I am installing all this on a wonderful Raspberry Pi kit called a "CrowPi." They had a successful KickStarter and are now selling a Raspberry Pi Educational Kit with an attached custom board with dozens of components. Rather than having to connect motion sensors, soud sensors, touch sensors, switches, buttons, and carry around a bunch of wires, you can experiment and play with stuff in a very organized case that also has a 7inch HDMI touch screen. They also have 21 great Python Video Courses on their YouTube Channel on how to get started with hardware. It's a joy of a device. More on that later. NOTE: I talked to the #CrowPi people and they gave me an Amazon COUPON that's ~$70 off! The coupon is 8EMCVI56, add it during checkout. The Advanced Kit is at #ref and includes everything, touchscreen, keyboard, mouse, power, SNES controllers, motors, etc. I will be doing a full review soon. Short review is, it's amazing. Now that .NET Core is installed, I can start exploring the fun happening over at It's filled with lots of new functionality inside of System.Device.Gpio. Remember that GPIO means "General Purpose Input/Output" which, on a Raspberry Pi, is connected to a ribbon cable on the CrowPi with lots of cool sensors ready to go! I could build my Raspberry Pi apps on my Windows/Mac/Linux machine and I'll find it much faster to compile. Then I can "scp" (secure copy) it over to the Pi. It's nice to point out that Windows 10 includes scp.exe now by default! In this example, by adding -r linux-arm I'm copying a complete self-contained app over the Pi, so don't actually need to install .NET Core like I did above. If instead, I didn't use -r (to declare a specific runtime) then I would need to make sure I've got the right versions on my dev box vs my RPi, so consider what's best for you. Here I am in my Windows machine that also has the same version of the .NET Core SDK installed. I'm in .\rpitest with a console app I made with "dotnet new console." Now I want to build and copy it over to the Pi.dotnet publish -r linux-armcd bin\Debug\netcore2.1\linux-arm\publishscp -r . pi@crowpi:/home/pi/Desktop/rpitest From the Pi, I'll need to "sudo chmod +x" the rpitest application to make sure it is executable. There's a brilliant video from Cam Soper that shows you in great detail how to run .NET Core 2.x on a Raspberry Pi and I recommend you check it out as well. IoT devices expose much more than serial ports. They typically expose multiple kinds of pins that can be programmatically used to read sensors, drive LED/LCD/eInk displays and communicate with our devices. .NET Core now has APIs for GPIO, PWM, SPI, and I²C pin types. These APIs are available via the System.Device.GPIO NuGet package. It will be supported for .NET Core 2.1 and later releases. There's some basic samples here to start with. From Microsoft: Most of our effort has been spent on supporting these APIs in Raspberry Pi 3. We plan to support other devices, like the Hummingboard. Please tell us which boards are important to you. We are in the process of testing Mono on the Raspberry Pi Zero. For now System.Device.Gpio is a prelease so you'll want to add a nuget.config to your project with the path to the dailies:<?xml version="1.0" encoding="utf-8"?><configuration> <packageSources> <clear /> <add key="" value="" /> <add key="" value="" /> </packageSources></configuration> Add a reference to System.Device.Gpio or (at the time of this writing) version 0.1.0-prerelease.19065.1. Now let's do something! Here I'm just blinking this LED!Console.WriteLine("Hello World!");GpioController controller = new GpioController(PinNumberingScheme.Board);var pin = 37;var lightTime = 300;controller.OpenPin(pin, PinMode.Output);try { while (true) { controller.Write(pin, PinValue.High); Thread.Sleep(lightTime); controller.Write(pin, PinValue.Low); Thread.Sleep(lightTime); }}finally { controller.ClosePin(pin);} Yay! Step zero works! Every cool IoT projects starts with a blinking LED! Do be aware that System.Device.Gpio is moving VERY fast and some of this code and the samples may not work if namespaces or class names change. It'll settle down soon. Great stuff though! Go get involved over at as they are actively working on drivers/abstractions for Windows, Linux, etc and you could even submit a PR for a device like an LCD or simple sensor! I've only been playing for an hour but I will report back as I try new experiments with my kids.

KDE Students Excel during Google Code-in 2018

2019-01-16 00:00:00

After many years of successful Google Code-in participation, this year we did it again! KDE attracted a number of students with exciting tasks for their eager young minds. Google Code-in is a program for pre-university students aged from 13 to 17 and sponsored by Google Open Source. KDE has always worked to get new people involved in Free and open source (FOSS) projects with the aim of making the world a better place. This year was no different. Our students worked very hard, and some of them already have their contributions committed to the KDE codebase! We designed tasks in a way that made them exciting for all students. Students who were not skilled in programming took on tasks of writing blogs or documentation. To help students who had no experience with FOSS or with the community, we set up introductory tasks for IRC and mailing lists, both of which are essential in FOSS as communication channels. The students who had some prior programming experience received tutorial tasks to get a better understanding of how KDE software works. Those types of tasks also helped them become familiar with the Qt framework on which all KDE software is based. Finally, students good at programming were put to work contributing to on-going KDE projects. They created new features or solved known bugs and wrote unit tests. We’re happy that some really enthusiastic and persistent students joined us this year. Thanks to their passion for programming, they completed many tasks and delivered quality code we merged into our project repositories. It wasn’t easy for the mentors to select winners, as every student had accomplished great things. Still, we finally settled on pranav and triplequantum (their GCI names). Finalists were TURX, TUX, UA and waleko. KDE would like to congratulate all the winners and finalists, and we warm-heartedly welcome all our new contributors! Author: Pranam Lashkari

WordPress To Show Warnings on Servers Running Outdated PHP Versions

2019-01-15 18:02:00

The WordPress open-source content management system (CMS) will show warnings in its backend admin panel if the site runs on top of an outdated PHP version. From a report: The current plan is to have the warnings appear for sites using a PHP version prior to the 5.6.x branch (5.6 or lower). The warnings will contain a link to a WordPress support page with information on how site owners can update their server's underlying PHP version. In instances where site owners are running their WordPress portals on top of tightly-controlled web hosting environments, the web host has the option to change this link with a custom URL pointing at its own support site. [...] Around 66.7 percent of all Internet sites run an unsupported PHP version, according to W3Techs. Almost a quarter of all internet sites run on top of a WordPress CMS.

arter97’s custom kernel and vendor images greatly improve the Xiaomi Mi Pad 4’s performance Xiaomi (and a lot of Chinese OEMs) have had a difficult time complying with the rules of the GNU GPL when it comes to releasing the kernel source code for their Android products. The company said they would start doing this 3 months after the release of a new product, but that wasn’t the case with the Xiaomi Mi Pad 4. The device launched in June of last year and, as of October, they had yet to comply with the GPL. Thankfully, they finally released it (a month after we reported on their tardiness) and it has helped developers work their magic on the device.

Programming: Python, Qt 6.0, and LLVM

The starting of new pygame project Hello, welcome back, due to busy managing the offline business as well as writing article for another website, therefore, no post had been created in the past few days. Qt 6 To Begin Early Stages Of Development In Git While Qt 6.0 isn't due out for the better part of two years still, early patches planned for Qt 6 are expected to begin taking shape within a Git staging branch. Lars Knoll laid out plans today to have a Qt 6 branch start for qtbase, since that's where most of the early stage Qt6 development will begin taking place. Already he's been collecting some patches from fellow developers and at least having this branch early will serve as a basis for staging until the Qt 6.0 development really heats up. The current Qt5 "dev" code would regularly merge into the Qt6 code-base, functions planned for removal in Qt6 would need to be first marked as deprecated by the Qt5 code, and binary compatibility breakage can begin. Intel Looking To Drop Their Nios II Backend From LLVM One of the lesser known compiler backends/targets by the LLVM compiler is Nios II, which is for the 32-bit embedded FPGA processor designs. Of course, Intel acquired Altera back in 2015 and has been focusing upon the Intel Stratix hardware as their current FPGA focus. For Nios II coverage there's long been an out-of-tree GCC-derived compiler while the LLVM back-end hasn't received much attention. It seems the LLVM support for Nios II isn't widely used as the Intel developers are now looking to drop this back-end. In fact, the Nios2 LLVM back-end with being broken for months before it was noticed. Additionally, the experimental target has never been full-featured to the extent that the Intel compiler developers would rather just drop the code. Apple Opens Up Swift/C LSP Based On Clangd Built atop LLVM's clangd server, Apple recently open-sourced SourceKit-LSP as a language server protocol for Swift and C-based languages. This allows for better integration with various IDEs and development tools. Language Server Protocols are a standardized protocol for communicating between integrated development environments / IDEs and servers providing various programming language specific features. These LSPs can be re-used by different development tools / editors while providing the necessary functionality for code completion, code formatting, syntax highlighting, and other features that are language-specific and better off re-used across projects rather than needing to be re-implemented each time. Writing Golang as a Python Dev I’ve gone through the Golang tutorial once before but in the last month or so, I fully dove into it. I started by writing a simple hello world web application. I found the implementation of the webserver so neat that most of the uses I’d have for a framework is redundant. The in-built libraries already take care of handling most of the use-cases I have. I did a couple of views and a couple of templates. It seems to be working well. As someone coming from Python, I keep tripping over types. I started my professional career with PHP and then moved to Python. Both of these languages aren’t very strongly typed by default. So it’s been fun to find errors and fix them. I learn more and more that I can’t be lazy. read more

407 Proxy Authentication Required - Evert Pot

2019-01-15 15:00:00

407 Proxy Authentication Required is an error a HTTP proxy returns if it requires authentication. It’s really similar to 401 Unauthorized. Example HTTP/1.1 407 Proxy Authentication Required Proxy-Authenticate: Basic; realm="Secured area" As you can see above, the response looks pretty similar to 401 and can use the same authentication schemes. This is an example of a client authenticating with a proxy: GET / HTTP/1.1 Proxy-Authorization: Basic d2VsbCBkb25lOllvdSBmb3VuZCB0aGUgc2Vjb25kIGVhc3RlciBlZ2cK If a clients connects to a server that requires authentication via a proxy that also requires authentication, both headers might appear in a request: GET / HTTP/1.1 Proxy-Authorization: Basic ZWFzdGVyIGVnZzpudW1iZXIgdGhyZWUK Authorization: Bearer c2VuZCBtZSBhIHR3ZWV0IG9yIHNvbWV0aGluZwo Usage HTTP proxies used to be more common. They can act like local caches or provide an additional layer of security in a corporate environment. These days they are less common for those purposes. Caching is not as needed, and the security layer is more often implemented with a VPN. Most HTTP proxies these days are reverse proxies, which is mostly transparent for HTTP clients. Basic and Digest authentication for proxies is widely supported by browsers and other HTTP clients. References RFC7235, Section 3.2 - 407 Proxy Authentication Required

Security: Back Doors and Metasploit

2019-01-15 14:22:57

Vulnerabilities found in building access system used by schools, governments Tenable Research discovered four zero-day vulnerabilities in PremiSys access control system from IDenticard (PremiSys IDenticard). The first, a hardcoded backdoor account, “allows attackers to add new users to the badge system, modify existing users, delete users, assign permission, and pretty much any other administrative function.” The ability to “give an attacker unfettered access to the badge system database, allowing him/her to covertly enter buildings by creating fraudulent badges and disabling building locks” is troubling considering tens of thousands of customers, ranging from K-12 schools, universities, government agencies, medical centers, and Fortune 500 companies, rely on IDenticard for secure key card access. Open-Source Metasploit Framework 5.0 Improves Security Testing Among the most widely used tools by security researchers is the open-source Metasploit Framework, which has now been updated with the new 5.0 release. Metasploit Framework is penetration testing technology, providing security researchers with a variety of tools and capabilities to validate the security of a given application or infrastructure deployment. With Metasploit, researchers can also test exploits against targets to see if they are at risk, in an attempt to penetrate the defensive measures that are in place. The 5.0 release of Metasploit introduces multiple new and enhanced capabilities, including automation APIs, evasion modules and usability improvements. "As the first major Metasploit release since 2011, Metasploit 5.0 brings many new features, as well as a fresh release cadence," Brent Cook, senior manager at Rapid7, wrote in a blog post. [...] Metasploit 5.0 now also brings improved usability for security researchers to test multiple targets at scale. "While Metasploit has supported the concept of scanners that can target a subnet or network range, using an exploit module was limited to only one host at a time," Cook wrote. "With Metasploit 5.0, any module can now target multiple hosts in the same way by setting RHOSTS to a range of IPs or referencing a host’s file with the file:// option." Usability also gets a boost with improved performance, including faster startup and searching capabilities than in previous versions of Metasploit. Additionally, with Metasploit 5.0, researchers are now able to write and use modules in any of three programming languages: Go, Python and Ruby. Overall, development for Metasploit 5.0 benefited from an updated process that included a stable branch that is used by Rapid7 and other distributions for everyday use and an unstable branch where new development can be rapidly added before it’s ready for broader consumption. read more

Serverless PHP on AWS Lambda

2019-01-15 13:01:01

Like, Simon Wardley, I think that serverless computing is an interesting space because the billing is granular (pay only when your code executes) and you don't need to worry about maintaining and provisioning servers or containers. So much so, that I maintain the Open Source PHP Runtime for Apache OpenWhisk which is available commercially as IBM Cloud Functions. There are other serverless providers, and AWS Lambda is the market leader, but until recently PHP support could most charitably described as "cumbersome." That all changed at the end of 2018 with Lambda's new runtime API and support for layers.

C Programming Language in 2019 and Python Leftovers

2019-01-15 12:08:34

State of C Programming Language in 2019 In four years’ time, C will reach its 50th birthday, an anniversary also shared with PL/M and Prolog. Unlike those two, C remains immensely popular, it’s in the top ten of virtually every programming language popularity survey. Linux is mostly written in C. Python‘s CPython implementation, Perl, Matz’s Ruby, about half of R, the MyISAM code for MySQL and even the first Java compiler were all written in C. The kernels of most operating systems (including Windows, Mac, Linux, iOS and Android) all feature C. Now we have a new C standard, C18, that was ratified a few months ago. A mere 198 Swiss Francs will buy the ISO/IEC 9899:2018 standard, all 520 pages of it; you can view the final draft of it for free, though, on (PDF) to get a sense of the document. It’s only really of use if you are a compiler writer who wants to be 100 percent conformant, or just curious. Remove audio from video with Python and FFmpeg Dockerizing Python Applications Docker is a widely accepted and used tool by leading IT companies to build, manage and secure their applications. Improve Your Code With Atomic Functions In your studies, you may have encountered the terms "atomic function" and "Don't Repeat Yourself (DRY)". Today, I'm going to demonstrate how these concepts work together to provide easily maintainable, easily testable, and beautiful code. In your studies, you may have encountered the terms "atomic function" and "Don't Repeat Yourself (DRY)". Today, I'm going to demonstrate how these concepts work together to provide easily maintainable, easily testable, and beautiful code. So... let's talk Pyramid Last year, I started working on a project that I truly believe(d) might change the world (cliche, right?). Like most developers, my first instinct at the outset was to make certain crucial decisions about the overall architecture of the project in view. First question that came to mind was the language to use for the backend of the web app, at least at the outset. To be clear, I am quite a Pythonista as I love everything about the language. Although I'm pretty much familiar with Java, Javascript and a little bit of Elixir, I knew there was no way I could go wrong with Python since I was going to be the only developer working on the project for months and I needed to churn out code quickly. Speed Up Your Python Program With Concurrency If you’ve heard lots of talk about asyncio being added to Python but are curious how it compares to other concurrency methods or are wondering what concurrency is and how it might speed up your program, you’ve come to the right place. read more

JavaScript Labels

2019-01-15 11:52:16

No matter how long you’ve been a JavaScript developer, there will always be language features that you didn’t know about until you saw them in a fringe piece of code. Your reaction generally is a bit like: One of those features I see developers quizically trying to figure out is JavaScript labels, which allow you […] The post JavaScript Labels appeared first on David Walsh Blog.

Arrow Functions in JavaScript

2019-01-15 10:02:01

Arrow functions are the most powerful feature in ES6, especially in TypeScript. Let's look at one simple example of this using a forEach loop. //Normal Statement with a callback function arrayOfItems.forEach(function(x) { updatedItems.push(x+1); }); //arrow function arrayOfItems.forEach((x) => { updatedItems.push(x+1); }); In a JavaScript class, we use this keyword to refer to the instance of the class .But here are some cases likemyObject.myMethod1() here this used inside my first method, which will refer to myObject. Another example you can with this snippet.

5 Best Python Frameworks for WebView Testing

2019-01-15 06:05:01

Python has become one of the most widely used programming languages. The reason behind its popularity is that it is extremely easy to use and allows you to create platform independent programs. It is a high-level language and has all the important features that make a good programing language. It also supports OOPs, i.e. Object Oriented Programming concepts. The syntax of Python is very different from C or C++ and simpler too. This makes it easy to learn and understand.

How fast can you multiply really big numbers?

2019-01-15 01:27:23

How long does it take to multiply very large integers? Using the algorithm you learned in elementary school, it takes O(n²) operations to multiply two n digit numbers. But for large enough numbers it pays to carry out multiplication very differently, using FFTs. If you’re multiplying integers with tens of thousands of decimal digits, the […]

Fedora: Releases, PHP and Fedora Test Day

2019-01-15 00:57:47

Updating release schedule tasks One thing that I noticed as I got settled in to this role last summer is that the Fedora release schedule tasks look a lot like they did when I first started contributing almost a decade ago. That’s not necessarily a bad thing — if it’s not broke, don’t fix it. but I suspect it’s less because we’re still getting releases out in the same way we did 10 years ago and more because we haven’t captured when reality has drifted from the schedule.

Mozilla: Firefox 67 Plans, Servo, TenFourFox FPR12b1

2019-01-14 23:39:25

Moving to a Profile per Install Architecture With Firefox 67 you’ll be able to run different Firefox installs side by side by default. Supporting profiles per installation is a feature that has been requested by pre-release users for a long time now and we’re pleased to announce that starting with Firefox 67 users will be able to run different installs of Firefox side by side without needing to manage profiles. This Week In Servo 123 In the past three weeks, we merged 72 PRs in the Servo organization’s repositories. TenFourFox FPR12b1 available TenFourFox Feature Parity 12 beta 1 is now available (downloads, hashes, release notes). As before, this is a smaller-scope release with no new features, just fixes and improvements. The big changes are a fix for CVE-2018-12404, a holdover security fix from FPR11 that also helps improve JavaScript optimization, and Raphael's hand-coded assembly language AltiVec-accelerated string matching routines with special enhancements for G5 systems. These replace the C routines I wrote using AltiVec intrinsics, which will be removed from our hacked NSPR libc source code once his versions stick. Unfortunately, we continue to accumulate difficult-to-solve JavaScript bugs. The newest one is issue 541, which affects Github most severely and is hampering my ability to use the G5 to work in the interface. This one could be temporarily repaired with some ugly hacks and I'm planning to look into that for FPR13, but I don't have this proposed fix in FPR12 since it could cause parser regressions and more testing is definitely required. However, the definitive fix is the same one needed for the frustrating issue 533, i.e., the new frontend bindings introduced with Firefox 51. I don't know if I can do that backport (both with respect to the technical issues and the sheer amount of time required) but it's increasingly looking like it's necessary for full functionality and it may be more than I can personally manage. read more

LibreOffice: First Quarter Without Work For TDF, Mohamed Trabelsi and Jim Raykowski, Report on the New LIbreOffice Help Pages Online Editor

2019-01-14 22:58:12

First Quarter Without Work For TDF I did pour volunteer work for LibreOffice and its antecessor for about sixteen years. I worked in different roles for the open source project during this long periode. The project consumed a lot of my spare time. But then I experienced a ‘nice’ communication experience inside the community, that showed me a lack of respect for my project work, its value and also for my person. Thus I decided to completely stop my pour volunteer work within the project three month ago. The LibreOffice extensions and templates website ( lost its maintainer and project reviewer since that time. Community Member Monday: Mohamed Trabelsi and Jim Raykowski I’ve been living in Kobe, Japan for three years now. I was Master student at Kobe Institute of Computing for two years, then I did internship for six months at iCRAFT Corp, a Japanese IT company in Kobe. And now I work as a Network Engineer at the same company. Outside of work, I’m usually playing soccer, watching movies, traveling around Japan with some friends and family, and going for some volunteering activities nearby.

GoDaddy is Injecting Site-Breaking JavaScript Into Customer Websites

2019-01-14 18:25:00

Web hosting service GoDaddy is injecting JavaScript into customer websites that could impact the overall performance of the website or even render it inoperable, according to Australian programmer Igor Kromin. From a report: GoDaddy's analytics system is based on W3C Navigation Timing, but the company's practice of unilaterally opting in paying customers to an analytics service -- tracking the visitors to websites hosted on GoDaddy services -- without forewarning is deserving of criticism. GoDaddy claims the technology, which it calls "Real User Metrics" (RUM), "[allows] us to identify internal bottlenecks and optimization opportunities by inserting a small snippet of javascript code into customer websites," that will "measure and track the performance of your website, and collects information such as connection time and page load time," adding that the script does not collect user information. The script name "Real User Metrics" is somewhat at odds with that claim; likewise, GoDaddy provides no definition of "user information." GoDaddy claims "most customers won't experience issues when opted-in to RUM, but the JavaScript used may cause issues including slower site performance, or a broken/inoperable website," particularly for users of Accelerated Mobile Pages (AMP), and websites with pages containing multiple ending tags.

How to Make Your Python Workers Scale Dynamically

2019-01-14 18:01:03

We’ve recently had an interesting opportunity to experiment with deploying modern Python workers at Rainforest. We used to host most of our stack on Heroku[1], but it was not a good fit for this particular use case. This post explains the challenge we were facing and how we solved it, while also mentioning a bunch of cool tools that make development and deployment much less painful than it was a few years ago. Dynamic Scaling for Python Workers So what was our task? We wanted to run Python workers, each for some time between a few minutes and a few hours. We also wanted to have the flexibility to support thousands of workers running simultaneously during high-traffic periods without paying for the infrastructure in times of low demand – basically dynamic scaling. When you’re used to building web applications, where a request taking more than 1s is considered bad and your demand is a little more constant, you have to slightly change your perspective and probably the tools you’re using. Heroku can work great for some things, but dynamic scaling is not really one of them (things like HireFire can help, but we found that we wanted a bit more flexibility).
