Programming: Java EE, Rust, JavaScript, RcppGetconf and More

2018-11-17 08:22:34

Free Online Java EE Development Course From Red Hat Available Now The Red Hat Training team is pleased to announce the release of Fundamentals of Java EE Development. This free training is hosted by our partner edX. edX is an open online course provider that now hosts three Red Hat courses, including Fundamentals of Red Hat Enterprise Linux and Fundamentals of Containers, Kubernetes, and Red Hat OpenShift. Enterprise Java (Java EE is now known as Jakarta EE) is one of the most in-demand and marketable programming platforms. With Fundamentals of Java EE Development, students learn the foundational skills needed to develop modern applications. Serving as an introduction to enterprise Java development using Red Hat Developer Studio and Red Hat JBoss Enterprise Application Platform, this course builds on students’ Java SE skills to teach the basic concepts behind more advanced topics such as microservices and cloud-native applications. New Rust Course - Building Reuseable Code with Rust This course is about the Rust programming language, but it’s not those general introductory course on basic Rust syntax. This course focus on the code reuse aspect of the Rust language. So we won’t be touch every language feature, but we’ll help you understand how a selected set of features will help you achieve code reuse. [...] snippet is not enough. What comes next naturally is to define a clear interface, or internal API between the modules (in a general sense, not the Rust mod). This is when traits comes in handy. Traits help you define and enforce interfaces. We’ll also discuss the performance impact on static dispatch vs. dynamic dispatch by using generics and trait object. Finally we talk about more advanced (i.e. you shouldn’t use it unless necessary) tool like macros, which will help do crazier things by tapping directly into the compiler. You can write function-like macros that can help you reuse code that needs lower level access. You can also create custom derive with macros. What is the MEAN stack? JavaScript web applications Most anyone who has developed web applications knows the acronym LAMP, which is used to describe web stacks made with Linux, Apache (web server), MySQL (database server), and PHP, Perl, or Python (programming language). Another web-stack acronym has come to prominence in the last few years: MEAN—signifying a stack that uses MongoDB (database server), Express (server-side JavaScript framework), Angular (client-side JavaScript framework), and Node.js (JavaScript runtime). RcppGetconf 0.0.3 Changes are minor. We avoid an error on a long-dead operating system cherished in one particular corner of the CRAN world. In doing so some files were updated so that dynamically loaded routines are now registered too. The performance impact of zeroing raw memory When you create a new variable (in C, C++ and other languages) or allocate a block of memory the value is undefined. That is, whatever bit pattern happened to be in the raw memory location at the time. This is faster than initialising all memory (which languages such as Java do) but it is also unsafe and can lead to bugs, such as use-after-free issues. There have been several attempts to change this behaviour and require that compilers would initialize all memory to a known value, usually zero. This is always rejected with a statement like "that would cause a performance degradation fo unknown size" and the issue is dropped. This is not very scientific so let's see if we could get at least some sort of a measurement for this. read more

Laravel News: Building a Laravel Translation Package – Wiring Up The Frontend

2018-11-16 19:33:36

The Laravel News site has posted the latest in their "Building a Laravel Translation Package" series of tutorials with a new post focusing on the frontend and getting it connected to the backend functionality. In the last installment of this series, we talked through the process of manipulating the translations in our application’s language files into a format where we are now in a position to start interacting with them. In this article, we’ll be wiring up the frontend ready to start building out the user interface which will aid users with the process of translation management. The UI will be developed using the community favorites, Tailwind CSS and Vue.js. The tutorial starts with the approach for the functionality, taking a more hybrid approach and using a balance of backend and frontend for the majority of the functionality. It then starts in on the technical parts to connect the two halves: adding the required routes creating the controllers building out the views to render the interface The majority of the post is then dedicated to the creation of the assets - the Javascript and CSS - to create the "framework" the functionality will use to work with the translations.

On the Zend blog there's a new tutorial posted by Enrico Zimuel covering the use of libsodium in PHP 7.2 to provide stronger encryption for your data. Recently, at ZendCon & OpenEnterprise 2018, I presented a session about the usage of Sodium in PHP 7.2. Here you can find the slides of this session. Sodium is a powerful library for modern cryptography. It is a portable, cross-compilable, installable and packageable fork of NaCl, a famous cryptographic tool designed by Prof. D.J. Bernstein. The tutorial begins with an outline of the Sodium encryption including the algorithms it can use and how it helps to prevent side-channel attacks. It then lists out some of the common use cases and provides a simple code sample showing how to use it to encrypt a simple message with a randomly generated key.

Qt/KDE: QtCon Brasil 2018, Qt 5.12 and Qt Creator 4.8.0 Beta 2

2018-11-16 17:30:23

Talking about Qt and Computer Vision at QtCon Brasil 2018 I had the opportunity to participate in QtCon Brasil 2018 as a speaker during the last weekend. It happened in São Paulo, which is a city that I haven’t visited for a long time. My talk was about the integration of Qt applications and Computer Vision, specially focused on the mobile environment with QtQuick and QML. During my presentation, I was focused on introducing some concepts to the people who just have heard or never had contact with Computer Vision. I talked a little bit about OpenCV, including an brief explanation about its modules and how they work, and I presented a little example of object recognition application made with QML (the code is available in the repository). Qt Quick Performance Improvements with Qt 5.12 LTS Qt 5.9 LTS already shows a great improvement of the overall performance compared to the previous long-term supported Qt 5.6 LTS release. These are summarized in a blog post about Performance Improvements with Qt 5.9 LTS and Qt Quick Performance Improvements on 64-bit ARM. With Qt 5.12 LTS we have continued to tune these further and taken a deeper look into the areas of QML engine memory consumption and JavaScript performance. Qt 5.9 LTS already shows a great improvement of the overall performance compared to the previous long-term supported Qt 5.6 LTS release. These are summarized in a blog post about Performance Improvements with Qt 5.9 LTS and Qt Quick Performance Improvements on 64-bit ARM. With Qt 5.12 LTS we have continued to tune these further and taken a deeper look into the areas of QML engine memory consumption and JavaScript performance. Qt 5.12 Lowering The QML Memory Consumption, Better JavaScript Performance As part of The Qt Company's ongoing improvements to their tool-kit and with Qt 5.12 being an LTS release, this cycle they focused a lot on improving the performance. Qt 5.12 LTS will be releasing in the next few weeks and as part of their performance push they have been working to lowering the memory consumption of the QML engine. The QML data structures have been optimized to reduce their size and better handling around cached objects. Qt Creator 4.8 Beta2 released We are happy to announce the release of Qt Creator 4.8.0 Beta2! This release comes with the many fixes that we have done since our first Beta release.

CloudWays Blog: PHP-FPM Cuts Web App Loading Times by 300%

2018-11-16 16:18:33

There's several ways to run PHP on various webservers out there and in a tutorial from the CloudWays blog they focus on one: using PHP-FPM and the performance gain it can give. Speed matters. Our engineers are always looking at ways on improving the stack. One of the major objectives of our stack integrations is to improve the speed of the overall processes of our stack. Keeping up with this practice, in a bid to increase speed of aspects of Managed Cloud Hosting coupled with constant improvements based on users feedback, Cloudways has now integrated PHP-FPM in all its servers. Owing to this integration, applications hosted on Cloudways servers are now going to perform up to 3x faster. The post starts with a look at why to choose PHP-FPM and shares some benchmarks of it in use versus the more typical mod_php shared module. It then gets into the implementation steps, linking to a step-by-step guide on how to implement it.

Nix – The Purely Functional Package Manager for Linux

2018-11-16 16:13:14

Nix is a powerful, purely functional package management system designed for reliable and reproducible package management, released under the terms of the GNU LGPLv2.1. It is the primary package management system in NixOS, a lesser known Linux distribution. Nix offers atomic upgrades and rollbacks, multiple versions of package installation, multi-user package management and effortless setup of build environments for a package, regardless of what programming languages and tools a developer is using. Under Nix, packages are built from a functional package language called “Nix expressions”. This functional approach to package management guarantees that installing or upgrading one package cannot break other packages. Nix also has multi-user support, which implies that normal (or non-privileged) system users can securely install packages and each user is identified by a profile (a collection of packages in the Nix store that appear in the user’s PATH). read more

5 Programming Languages Every Programmer Should Learn

2018-11-16 15:13:04

I read somewhere that programmers should learn a new programming language every year (I think it's code complete, not sure, though), but if you cannot do so, I suggest you at least learn the following five programming languages to do well in your career. Every company loves polyglot programmers and an well-rounded coder, who is versatile enough languages to write a quick script, and can also write complex Java programs, is a valuable coder indeed. In fact, it's almost mandatory for a senior developer to learn more than one language.

Big Data Languages, Tools, and Frameworks

2018-11-16 14:01:02

To understand the current and future state of big data, we spoke to 31 IT executives from 28 organizations. We asked them, "What are the most prevalent languages, tools, and frameworks you see being used in data ingestion, analysis, and reporting?" Here's what they told us: Python, Spark, Kafka With big data and the push into AL/ML, Scala and Python are leading with Apache Spark gaining popularity. Move from OLAP cubes and data warehouses to less organized structures applying ML with Python. Developers are writing Python ML models due to the library support that’s out there.  Kafka for streaming ingest. R and Python for programming. Java is prevalent. SQL hasn’t gone away. Not big data’s best friend but opens access to a broader range of people can access the data. Gartner has SQL on Hadoop coming out of the trough of disillusionment.  We see a lot of Hadoop, Spark, and Kafka. The emerging tech is in data warehousing where there is a lot of interest in Redshift, Snowflake, and Big Query. ML is out there. Added capabilities for TensorFlow. Early interest there. The third is Kubernetes. A lot of interest in leveraging to scale out consumption.  Other open source tools are widely used, such as Spark, R, and Python. This is why platforms offer an integration with these open source tools. In our workflow, it is possible to introduce a new node in which to script Python, R or Spark code. At execution, the node will execute the code and will become part of the node pipeline in the workflow.  For a while, R was predominant, especially in data science operationalizing models. Now the real innovation is around Python. A lot of tools, libraries, and support. People are starting to explore Spark and Kafka. Spark processes huge volumes at speed. Kafka is a messaging system for getting data into Spark. R is great for analyzing historical data. Take the model, get real-time data, and help marshal data so it can be run in real-time and apply the models.  Some of the common tools and frameworks include in-memory relational databases like VoltDB, Spark, Storm, Flink, Kafka, and NoSQL databases.   We provide a LINQ-type API for all CRUD data operations which can be called from a variety of languages such as C#, Go, Java, JavaScript, Python, Ruby, Scala, and Swift. Designed as a high performance (predictable low latency) database, our primary data access was created to be programmatic rather than declarative and as such, we do not currently support SQL. As our customers add analysis to the workloads they are currently performing, we will be adding SQL support. We support exporting data to backend data warehouses and data lakes for analysis. For ingestion, tools such as Kafka and Kinesis are gaining traction as the default data communications pipes within our customers.  We see SQL as the primary protocol used by companies of all sizes for data residing in our platform. For deployment management, we have seen a rapidly growing use of Docker and Kubernetes. For data ingestion, Apache Kafka is used by many of our customers and we recently announced the certification of our Kafka Connector within the Confluent partner program. For analysis, we frequently see Apache Spark used along with Apache Ignite as an in-memory data store.  Apache Kafka has become, essentially, a standard for streaming high volumes of data (particularly sensor data) into data analytical platforms in near real-time at ingest. For the highest analytical performance, in-database machine learning and advanced analytics are becoming an increasingly important way for organizations to deliver predictive analytics at scale. For reporting, there are a variety of data visualization tools on the market today – from Tableau to Looker to Microsoft Power BI to IBM Cognos to MicroStrategy and many others. Business analysts have never had more options to report on and visualize data. However, they should insist that their underlying data analytical platform has the scale and performance to enable them to get insight from the largest volumes of data with complete accuracy in seconds or minutes, not after the business opportunity has passed.  We leverage several data ingestion and orchestration tools, with Apache Kafka and NIFI projects being the most prevalent. We use Hadoop YARN with HBASE/HDFS for our persistence layer, we take advantage of data processing, predictive modeling, analytics, and deep learning projects such as Apache Zeppelin, Spark/Spark Streaming, Storm, SciKit-Learn, and Elasticsearch. In addition to these open source projects above, we leverage Talend, Pentaho, Tableau, and other best in class commercial licensed tools. TensorFlow, Tableau, PowerBI 1) We use Amazon Athena (Apache Presto) for log analysis. 2) We use Mode Analytics for data visualizations and Reporting. 3) We use TensorFlow to analyze traffic patterns.  Data science from an ML perspective. Availability of DL frameworks, TensorFlow, Pytorch, Keras, Caffe has made a huge difference to apply ML and create models for large-scale data.  Working through the platforms as a way to deliver insights at scale. BI use cases are trying to scale analysts. Tableau, PowerBI, MicroStrategy, TIBCO, and Qlik try to expand the number of people dashboards are in front of.  We see a lot of Spark as organizations are moving away from MapReduce. Java and Python are popular. Kafka is being used for ingestion. Visual Arcadia Data, Tableau, Qlik, and PowerBI for visualization.  Many projects use multiple languages and multiple analytics tools. We see a lot of SQL use, of course, and data science-oriented languages such as Python and R, but also a significant use of classic programming languages such as Java and C#. For data science, the top package we’re seeing as an adjunct to our products is TensorFlow, followed closely by self-service BI tools such as Tableau, PowerBI, and ClickView. Other Open source. More are moving to streaming data. This is driven by a need/desire for real-time answers. It depends on the project. We see multiple mechanisms being used for ingestion, enrichment, document classifiers. SciByte, Thompson Reuters – ontologies, intelligent tagging tools to drill down into the data. Personality insights, sentiment analysis enrichment of the data. The customer drives what they use from the browser. Customers are looking for how to build off tools they already have. SQL is still the language for big data. Works on top of Hadoop and other databases. OData isn’t that new, but people are using it from server-side and client-side. Others use GraphQL to dynamically query and get data. There is a lot of new technology on the server side. MongoDB does certain things well. We're getting more specific about what they are offering. Redis is good for caching. S3 is useful for data storage with Elasticsearch and S3 as the backend. More clearly-defined technologies and design patterns. People who use R and Python stick with what they use. There are a number of APIs in the system with more support. From an ingestion point of view, you want to offer as many ways to get data into and out of the system as possible. Support as many tools as possible. This is no critical mass. Cater to the talent. Developer tools and APIs support a wide range of both. Larger companies would like people using the same tool for BI and data science since they have a mix of tools and it's hard to standardize thousands of people on one tool. The way to integrate with different backends and accelerate production varies from tool to tool. We provide integration, acceleration, and a catalog of what the data is and the semantic meaning of the data. The catalog is centrally located in the platform. Pull security, integration, and acceleration into a central open source layer that works with all tools and data sources. The big data world is quickly evolving in so many ways across all environments—on-premises, in the cloud, etc. We see lots of variations of languages, execution engines, and data formats. Our core value is allowing customers to bypass having to deal with all those different tools and standards. With the drag and drop, no code environment that we deliver, customers don’t have to code anything by hand. This allows them to develop data pipelines once as part of a repeatable framework and then deploy them en mass regardless of the technology, platform, or language. For example, we have customers that have used Infoworks to implement on-premises on Cloudera once and then run those same pipelines without re-coding on Google Cloud using Dataproc. Here’s who we spoke to:

Qt/KDE: Qt for Python, Inkscape Dark Theme on KDE Plasma, Atelier at Maker Faire and QtCon 2018!

2018-11-16 05:00:22

Python and Qt: 3,000 hours of developer insight With Qt for Python released, it’s time to look at the powerful capabilities of these two technologies. This article details one solopreneur’s experiences. [...] The big problem with Electron is performance. In particular, the startup time was too high for a file manager: On an admittedly old machine from 2010, simply launching Electron took five seconds. I admit that my personal distaste for JavaScript also made it easier to discount Electron. Before I go off on a rant, let me give you just one detail that I find symptomatic: Do you know how JavaScript sorts numbers? Alphabetically. ’nuff said. After considering a few technologies, I settled on Qt. It’s cross-platform, has great performance and supports custom styles. What’s more, you can use it from Python. This makes at least me orders of magnitude more productive than the default C++. Inkscape Dark Theme on KDE Plasma On KDE Plasma, it's very easy to setup Inkscape Dark Theme. To do so, go to System Settings > Application Style > GNOME/GTK+ Style > under GTK+ Style: switch all themes to Dark ones and give check mark to Prefer Dark Theme > Apply. Now your Inkscape should turned into dark mode. To revert back, just revert the theme selections. This trick works on Kubuntu or any other GNU/Linux system as long as it uses Plasma as its desktop environment. Atelier at Maker Faire and QtCon 2018! On the weekend of November 3 and 4, it happened on Rio de Janeiro the first Maker Faire of Latin America. And I was able to do a talk about Atelier and the current status of our project. The event hold more than 1.500 people on the first day, that saw a lot of talks and the exposition of makers of all over the country that came to Rio to participate in this edition of the Maker Faire. read more

Compiling C# to WASM with Mono and Blazor then Debugging .NET Source with Remote Debugging in Chrome DevTools

2018-11-16 02:45:00

Blazor quietly marches on. In case you haven't heard (I've blogged about Blazor before) it's based on a deceptively simple idea - what if we could run .NET Standard code in the browsers? No, not Silverlight, Blazor requires no plugins and doesn't introduce new UI concepts. What if we took the AOT (Ahead of Time) compilation work pioneered by Mono and Xamarin that can compile C# to Web Assembly (WASM) and added a nice UI that embraced HTML and the DOM? Sound bonkers to you? Are you a hater? Think this solution is dumb or not for you? To the left. For those of you who want to be wacky and amazing, consider if you can do this and the command line:$ cat hello.csclass Hello { static int Main(string[] args) { System.Console.WriteLine("hello world!"); return 0; }}$ mcs -nostdlib -noconfig -r:../../dist/lib/mscorlib.dll hello.cs -out:hello.exe$ mono-wasm -i hello.exe -o output$ ls outputhello.exe index.html index.js index.wasm mscorlib.dll Then you could do this in the browser...look closely on the right side there. You can see the Mono runtime compiled to WASM coming down. Note that Blazor IS NOT compiling your app into WASM. It's sending Mono (compiled as WASM) down to the client, then sending your .NET Standard application DLLs unchanged down to run within with the context of a client side runtime. All using Open Web tools. All Open Source. So Blazor allows you to make SPA (Single Page Apps) much like the Angular/Vue/React, etc apps out there today, except you're only writing C# and Razor(HTML). Consider this basic 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 hit the button, it calls some C# that increments a variable. That variable is referenced higher up and automatically updated. This is trivial example. Check out the source for FlightFinder for a real Blazor application. This is stupid, Scott. How do I debug this mess? I see you're using Chrome but seriously, you're compiling C# and running in the browser with Web Assembly (how prescient) but it's an undebuggable black box of a mess, right? I say nay nay!C:\Users\scott\Desktop\sweetsassymollassy> $Env:ASPNETCORE_ENVIRONMENT = "Development"C:\Users\scott\Desktop\sweetsassymollassy> dotnet run --configuration DebugHosting environment: DevelopmentContent root path: C:\Users\scott\Desktop\sweetsassymollassyNow listening on: http://localhost:5000Now listening on: https://localhost:5001Application started. Press Ctrl+C to shut down. Then Win+R and run this command (after shutting down all the Chrome instances)%programfiles(x86)%\Google\Chrome\Application\chrome.exe --remote-debugging-port=9222 http://localhost:5000 Now with your Blazor app running, hit Shift+ALT+D (or Shift+SILLYMACKEY+D) and behold. Feel free to click and zoom in. We're at a breakpoint in some C# within a Razor page...in Chrome DevTools. What? How? Blazor provides a debugging proxy that implements the Chrome DevTools Protocol and augments the protocol with .NET-specific information. When debugging keyboard shortcut is pressed, Blazor points the Chrome DevTools at the proxy. The proxy connects to the browser window you're seeking to debug (hence the need to enable remote debugging). It's just getting started. It's limited, but it's awesome. Amazing work being done by lots of teams all coming together into a lovely new choice for the open source web.

TutsPlus.com: Write to Files and Read Files With PHP

2018-11-15 16:41:04

TutsPlus.com has continued their series of posts covering some of the basics of the PHP language with their latest article. In this newest tutorial they cover reading from and writing to files using functionality already included with the language. In this tutorial, you'll learn several important functions in PHP which are sufficient for all your basic file reading and writing needs. You'll learn how to read a file, write to a file, write to a text file, and check if a file exists. Luckily, PHP provides a lot of functions to read and write data to files. In this tutorial, I'll show you the easiest ways to read data from a local or remote file and how to use flags to write to files exactly how we want. The tutorial is broken down into several sections: checking if a file exists reading data from a file writing data to a file reading and writing data to files Each section comes with a bit of description and code examples showing it in action. The post wraps up with some final thoughts and "gotchas" that you need to know when working with files in PHP (especially large ones).

The Internet Has a Huge C/C++ Problem and Developers Don't Want to Deal With It

2018-11-15 16:40:00

What do Heartbleed, WannaCry, and million dollar iPhone bugs have in common? From a report: One bug affects iPhones, another affects Windows, and the third affects servers running Linux. At first glance these might seem unrelated, but in reality all three were made possible because the software that was being exploited was written in programming languages which allow a category of errors called "memory unsafety." By allowing these types of vulnerabilities, languages such as C and C++ have facilitated a nearly unending stream of critical computer security vulnerabilities for years. Imagine you had a program with a list of 10 numbers. What should happen if you asked the list for its 11th element? Most of us would say an error of some sort should occur, and in a memory safe programming language (for example, Python or Java) that's what would happen. In a memory unsafe programming language, it'll look at wherever in memory the 11th element would be (if it existed) and try to access it. Sometimes this will result in a crash, but in many cases you get whatever happens to be at that location in memory, even if that portion of memory has nothing to do with our list. This type of vulnerability is called a "buffer-overflow," and it's one of the most common types of memory unsafety vulnerabilities. HeartBleed, which impacted 17 percent of the secure web servers on the internet, was a buffer-overflow exploit, letting you read 60 kilobytes past the end of a list, including passwords and other users' data.

Larry Garfield: Book review - Functional Programming in PHP

2018-11-15 15:28:47

Larry Garfield has posted a book review to his Steemit site giving his thoughts about the "Functional Programming in PHP" book from php[architect] press. I was asked by php[architect] a while back to review "Functional Programming in PHP, 2nd Ed" by Simon Holywell. I've been sitting on this review for a while, so it's time to finally get it done. He starts with some of the usual disclosures about receiving the book (for free), what the review is based on and that the opinions are his alone. He goes on to share some of his initial impressions of the book and whether he feels it's a good book to recommend to those wanting to start out with functional programming in PHP. He also points out that, while the book was published in 2016 the recommended PHP version even then was quite old (v5.4). He covers some of the topics that the book covers, noting that many of them, while interesting, don't add much to the overall book. He does focus on one chapter and how, at the beginning, it showed promise but quickly moved towards using 3rd party libraries for more complex operations. He finishes the review by answering the question: "does this book make me care about functional programming in PHP?"

Are HTML Pages Really Static? Think Again!

2018-11-15 14:17:34

According to the definition of a static page - "It shows information exactly as it is stored." So, if you are building a page that shows information from the database (dynamic), then you will use a server-side page like .php/.aspx/.cshtml. As a web developer, I have heard quite often that, "an HTML page is a static page, so it cannot be used to show dynamic content." This sounds fair but it is not totally correct. Let's discuss why an HTML page is not really a static page.

Although a lot of built-in functionality exists for all sorts of scientific computations, Scilab also includes its own programming language, which allows you to use that functionality to its utmost. If you prefer, you instead can use this language to extend Scilab's functionality into completely new areas of research. Some of the functionality includes 2D and 3D visualization and optimization tools, as well as statistical functions. Also included in Scilab is Xcos, an editor for designing dynamical systems models. Several options exist for installing Scilab on your system. Most package management systems should have one or more packages available for Scilab, which also will install several support packages. Or, you simply can download and install a tarball that contains everything you need to be able to run Scilab on your system. Once it's installed, start the GUI version of Scilab with the scilab command. If you installed Scilab via tarball, this command will be located in the bin subdirectory where you unpacked the tarball. When it first starts, you should see a full workspace created for your project. Figure 1. When you first start Scilab, you'll see an empty workspace ready for you to start a new project. On the left-hand side is a file browser where you can see data files and Scilab scripts. The right-hand side has several panes. The top pane is a variable browser, where you can see what currently exists within the workspace. The middle pane contains a list of commands within that workspace, and the bottom pane has a news feed of Scilab-related news. The center of the workspace is the actual Scilab console where you can interact with the execution engine. Let's start with some basic mathematics—for example, division: --> 23/7 ans = 3.2857143 As you can see, the command prompt is -->, where you enter the next command to the execution engine. In the variable browser, you can see a new variable named ans that contains the results of the calculation. Along with basic arithmetic, there is also a number of built-in functions. One thing to be aware of is that these function names are case-sensitive. For example, the statement sqrt(9) gives the answer of 3, whereas the statement SQRT(9) returns an error. There also are built-in constants for numbers like e or pi. You can use them in statements, like this command to find the sine of pi/2: Go to Full Article

Programming: WebRender, Healthcare Design Studio GoInvo, PHP Boost and Google Cloud Platform (GCP)

2018-11-15 12:51:26

Mozilla GFX: WebRender newsletter #30 Hi! This is the 30th issue of WebRender’s most famous newsletter. At the top of each newsletter I try to dedicate a few paragraphs to some historical/technical details of the project. Today I’ll write about blob images. WebRender currently doesn’t support the full set of graphics primitives required to render all web pages. The focus so far has been on doing a good job of rendering the most common elements and providing a fall-back for the rest. We call this fall-back mechanism “blob images”. The general idea is that when we encounter unsupported primitives during displaylist building we create an image object and instead of backing it with pixel data or a texture handle, we assign it a serialized list of drawing commands (the blob). For WebRender, blobs are just opaque buffers of bytes and a handler object is provided by the embedder (Gecko in our case) to turn this opaque buffer into actual pixels that can be used as regular images by the rest of the rendering pipeline. Healthcare Design Studio GoInvo Releases Open Source Research on Loneliness [Ed: Very odd if not 'creative' use of the term Open Source] PHP Lands Preload Feature, Boosting Performance In Some Cases 30~50% PHP developers unanimously approved and already merged support for the new "preloading" concept for this web server language. PHP preloading basically allows loading PHP code that persists as long as the web server is running and that code will always be ready for each subsequent web request, which in some cases will dramatically speed-up the PHP performance on web servers. While PHP has long supported caching to avoid PHP code recompilation on each new web request, with each request PHP has still had to check to see if any of the source file(s) were modified, re-link class dependencies, and similar work. PHP preloading allows for given functions/classes to be "preloaded" that will survive as long as the web server is active. It effectively allows loading of functions or entire/partial frameworks that will then be present for each new web request just as if it were a built-in function. Google Announces a Managed Cron Service: Google Cloud Scheduler Google announced a new Service on the Google Cloud Platform (GCP) - Cloud Scheduler, a fully managed cron job service that allows any application to invoke batch, big data and cloud infrastructure operations. The service is currently available in beta. With Google Cloud Scheduler customers can use the cron service with no need to manage the underlying infrastructure. There is also no need to manually intervene in the event of transient failure, as the services retries failed jobs. Furthermore, customers will only pay for the operations they run -- GCP takes care of all resource provisioning, replication and scaling required to operate Cloud Scheduler.

Gradle Goodness: Generate Javadoc in HTML 5

2018-11-15 11:04:01

Since Java 9, we can specify that the Javadoc output must be generated in HTML 5 instead of the default HTML 4. We need to pass the option -html5 to the javadoc tool. To do this in Gradle, we must add the option to the javadoc task configuration. We use the addBooleanOption method of the options property that is part of the javadoc task. We set the argument to html5 and the value to true. In the following example, we reconfigure the javadoc task to make sure the generated Javadoc output is in HTML 5:

Web Development and Advanced Techniques with Linux on Windows (WSL)

2018-11-14 02:36:00

I've posted several times on the Windows Subsystem for Linux that allows you to run Linux on Windows 10 without a VM. Check out my YouTube on Editing code and files on Windows Subsystem for Linux on Windows 10. There's just one rule. You can mess with Windows files from Linux but you can't mess with Linux files from Windows. Otherwise, go crazy and enjoy. Here's some of my previous posts you should check out: The year of Linux on the (Windows) Desktop - WSL Tips and Tricks Setting up a Shiny Development Environment within Linux on Windows 10 Installing Fish Shell on Ubuntu on Windows 10 Writing and debugging Linux C++ applications from Visual Studio using the "Windows Subsystem for Linux" Ubuntu now in the Windows Store: Updates to Linux on Windows 10 and Important Tips WSL is pretty fantastic although its disk access is slower than native Linux, I find myself using it every day. If you want to setup Linux on your Windows 10 machine, just turn it on, then head over to the Windows Store and search for "Linux." You can turn on Linux on Windows 10 by typing "Windows Features" and checking "Windows Subsystem for Linux." Then get a Linux from the Windows Store. If you prefer to use PowerShell and do it in one line, just do this from an Admin PowerShell prompt:Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux Then go get any one (or more!) of these from the Store: Ubuntu OpenSUSE SLES Kali Linux Debian GNU/Linux When you're in a Windows shell like PowerShell or CMD you might want to run Linux and/or jump comfortably between shells. You can do that in a few ways. The best and recommended way is running "wsl.exe" as that will start up your default distro. You can also just type the name of the distro. So I can type "ubuntu" and get in there directly. You can type "bash" but that's not recommended if you've changed shells. If you've set up zsh or fish and type bash, it's gonna still try to run bash. Here I've typed wslconfig and you can see I've got both Ubuntu and Debian installed, with Ubuntu as the default when I type "wsl."C:\Users\scott>wslconfig /listWindows Subsystem for Linux Distributions:Ubuntu-18.04 (Default)Debian Now that I know how to run wsl from anywhere I can even pipe stuff in and out it Linux from outside. For example here I am in cmd.exe but I'm calling commands in Linux, that come out, then back in, etc. You can mix and match however you'd like!C:\dev>type hello.shecho HelloC:\dev>wsl cat /mnt/c/dev/hello.sh | wsl fromdos | wsl /bin/shHello This means even when I'm in CMD or PowerShell I can use Linux commands that are convenient or familiar to me. For example, here I'm piping a Windows Update log file into a the Linux command sha1sum command. Note the use of - to accept standard input - even though that input is from Windows!C:\Users\scott\Desktop>type WindowsUpdate.log | wsl sha1sum -3b48adce8f6c9cb816e8845d824dacc0440ca1b8 - Sweet. There's a number of nice advanced techniques if you want to make your WSL installations smarter AND automatically configured.  You can make a file in /etc/wsl.conf to affect your DNS, metadata and driving mounting. When you are in a WSL shell, your Windows drive (your main drive) is at /mnt/c. So here is my Windows desktop as viewed from WSL: I most of my dev work in /mnt/d/github for example. That way I can use VS Code from Windows but run Node/Ruby/Go/Whatever from WSL. I keep my files on my Windows drive, edit them in VS Code, but run things in WSL. Again, never use Windows utilities to reach into and/or edit files on the WSL/Linux subsystem. Also, always been conscious of your CR/LF situation, and be real conscious if you're going to run git in both Windows and WSL. Here's VS Code at the top, WSL/Ubuntu running Node at the bottom, and the local node app running in Edge on Windows on the lower right. We are sharing file systems and network port space: You can even share environment variables between WSL and Windows with a special environment variable called WSLENV. This is pretty advanced but super powerful. Read this carefully. You make a environment variable that is a list of names of other variables that you want translated between environments. That means you can do something like this. I'm in WSL and I have an environment variable that points to a location on the filesystem. I need it to be correct in both worlds. scott@IRONHEART:/mnt/d$ export MYLINUXPATH=/mnt/d/github/expresstestscott@IRONHEART:/mnt/d$ export WSLENV=MYLINUXPATH/pscott@IRONHEART:/mnt/d$ cmd.exeD:\>echo %MYLINUXPATH%D:\github\expresstest Read that carefully. It's awesome and it's very configurable. There's lots of users of WSL and many have assembled great lists of resources like Awesome-WSL by Hayden. It's also worth pointing out that WSL is just now one console you can choose from. There's PowerShell, CMD.exe, and a half dozen Linuxes. You can even make your own custom Linux Distro for your company if you like. And there's a whole world of 3rd party Consoles that sit on top of/replace conhost.exe so you can have consoles with tabs, cool fonts, ones based on web tech, whatever! You can even choose WSL/bash as your default shell in Visual Studio Code if you'd like with Ctrl+~. Hope this gets you started with Linux on Windows. What did I miss? Sound off in the comments.

Google Aims to Increase Interoperability of Web and Native Apps with Writable Files API

2018-11-13 19:42:36

Google is currently designing an API to increase the interoperability of web applications with native applications. Google is calling it the Writable Files API, and is asking for the developer community's support in the design process. Not only is syncing functionality across native and web applications difficult in itself, the concept requires significant access to user data and opens the API to potential abuse.

Graphics: Vulkan, Wayland, AMD, Mesa and Vulkan

2018-11-13 16:31:59

Vulkan 1.1.92 Released, Finally Allows For Chunked HTML Documentation Vulkan 1.1.92 is out today to mark the newest specification update to this high-performance graphics/compute API. With it just being one week since Vulkan 1.1.91 that brought some new/improved extensions, there isn't any new extensions to find with Vulkan 1.1.92. But there are a number of documentation/specification corrections and clarifications. Wayland Protocols 1.17 Brings Explicit Synchronization & Primary Selection Jonas Ådahl of Red Hat today released a new version of Wayland-Protocols, the collection of stable and unstable protocols for extending Wayland functionality. With the Wayland-Protocols 1.17 release the big new feature is the initial (unstable) version of linux-explicit-synchronization. The Wayland explicit synchronization protocol provides a means of explicit per-surface buffer synchronization. This synchronization protocol is based on Google Chromium's extension (zcr_linux_explicit_synchronization_v1) and lets clients request this explicit synchronization on a per-surface basis. Google, Intel, and Collabora were involved in the formation of this extension. The Radeon GCN Backend Is Still Being Worked On For GCC, GCC 9 Deadline Looms Back in September Code Sourcery / Mentor Graphics posted their new Radeon GCN port for the GNU Compiler Collection (GCC). Two months later this port is still being worked on but not yet ready for mainline. This Radeon GCN back-end for GCC is being done with a focus on GPU computing with eventually a goal of allowing OpenMP / OpenACC offloading to newer AMD GPUs. At this current stage, single-threaded C and Fortran programs can be built for Radeon GPUs with this compiler but the multi-threading API offloading bits are still coming about. This back-end has been focused on Fiji/Tonga support and newer. AMDVLK Vulkan Driver Sees Its First Tagged Release In the nearly one year that the AMDVLK official Vulkan driver has been open-source there hasn't been any "releases" but rather new code drops on a weekly basis that is pushed out of their internal development repositories. But surprisingly this morning is now a v2018.4.1 release tag for this open-source AMD Vulkan Linux driver. The AMDVLK public source repositories have just been perpetual Git while AMD pulls from their internal repositories when building out their official closed-source Windows/Linux Radeon Software driver releases (that also use their closed-source shader compiler currently rather than the open-source AMDGPU LLVM back-end, as used by the public AMDVLK sources). Waking up this morning there is now the first release tag in AMDVLK as v2018.4.1. Mesa Drops Support For AMD Zen L3 Thread Pinning, Will Develop New Approach It was just a few months back that the Mesa/RadeonSI open-source AMD Linux driver stack received Zen tuning for that CPU microarchitecture's characteristics. But now AMD's Marek Olšák is going back to the drawing board to work on a new approach for Zen tuning. Just a few days ago I wrote about another developer wanting to toggle the support around L3 thread pinning as it was found to hurt the RadeonSI Gallium3D performance in at least some Linux games. At that point the goal was to allow making it a DriConf tunable that could then be adjusted a per-game/app basis, but it turns out the gains aren't there to keep it around. Mesa Gets Testing Patches For New Zen Optimization Around Thread Pinning It was just yesterday that the AMD Zen L3 thread pinning was dropped from Mesa due to that optimization not panning out as intended for benefiting the new AMD processors with the open-source Linux graphics driver stack. Lead Mesa hacker Marek Olšák is already out with a new Zen tuning implementation that may deliver on the original optimization goal. The first patch posted by Marek as part of his new tuning effort is to regularly re-pin the driver threads to the core complex (CCX) where the application thread is. Basically, when Mesa is being used without the glthread (OpenGL threading) behavior, keep chasing the application/game thread on the processor so it will be part of the same CCX and share a cache. This chasing is done rather than explicitly pinning the application thread. The Shiny New Features Of Mesa 18.3 For Open-Source Intel / Radeon Graphics Drivers Being well into the Mesa 18.3 feature freeze and that quarterly update to these open-source OpenGL/Vulkan drivers due out in about two weeks, here is a look at all of the new features and changes you can expect to find with this big update. NVIDIA released a new 415.13 beta driver recently for Linux One I completely forgot to post about here, NVIDIA recently released the 415.13 beta driver for Linux. Released on the 8th of November, it includes a number of interesting fixes, including an issue fixed with WINE where it might crash on recent distribution releases. Nice to see WINE get some focus, since things like this can affect Valve's Steam Play. read more

400 Bad Request - Evert Pot

2018-11-13 15:00:00

400 Bad Request is the first error code. Every status that starts with a 4 indicates that the client did something wrong. If the status starts with a 5 it means that the server did something wrong. 400 Bad Request is used as a generic error code. It’s a useful default error code if there’s no specific error code that’s a better fit. There’s often a lot of discussion about which 4xx code is the most appropriate for any different situations. This might be because there’s many, and it’s not always super clear what the distinctions between them are. The most important thing to remember when selecting the appropriate code is: “can a generic client do something with this response?”. If the answer is no, it might not matter as much which error code is returned. For example, when a client sees a 401 it might know to show a login window. When a client sees a 403, it might know to tell the end-user that the reason their operation failed, was because of permissions-related issues. Those are good reasons to show an error code, but those reasons don’t always exists. For those cases it’s fine to just use the generic status code 400. Response bodies When returning any error, you should also return a response body with more information about the failure. If your client is a browser, this might be user-friendly html page. If your client is some kind of JSON-based client, it might be good idea to use the standard application/problem+json response code. Example HTTP/1.1 400 Bad Request Content-Type: application/problem+json { "type": "https://example.org/impolite", "title": "Request was not polite enough", "detail": "HTTP requests must be made using a 'Please' HTTP header. } References RFC7231, Section 6.5.1 - 400 Bad Request RFC7807 - Problem details for HTTP APIs How to think about HTTP Status codes - Article by Mark Nottingham.

Automate Sysadmin Tasks with Python's os.walk Function

2018-11-13 12:30:00

by Reuven M. Lerner Using Python's os.walk function to walk through a tree of files and directories. I'm a web guy; I put together my first site in early 1993. And so, when I started to do Python training, I assumed that most of my students also were going to be web developers or aspiring web developers. Nothing could be further from the truth. Although some of my students certainly are interested in web applications, the majority of them are software engineers, testers, data scientists and system administrators. This last group, the system administrators, usually comes into my course with the same story. The company they work for has been writing Bash scripts for several years, but they want to move to a higher-level language with greater expressiveness and a large number of third-party add-ons. (No offense to Bash users is intended; you can do amazing things with Bash, but I hope you'll agree that the scripts can become unwieldy and hard to maintain.) It turns out that with a few simple tools and ideas, these system administrators can use Python to do more with less code, as well as create reports and maintain servers. So in this article, I describe one particularly useful tool that's often overlooked: os.walk, a function that lets you walk through a tree of files and directories. os.walk Basics Linux users are used to the ls command to get a list of files in a directory. Python comes with two different functions that can return the list of files. One is os.listdir, which means the "listdir" function in the "os" package. If you want, you can pass the name of a directory to os.listdir. If you don't do that, you'll get the names of files in the current directory. So, you can say: In [10]: import os When I do that on my computer, in the current directory, I get the following: In [11]: os.listdir('.') Out[11]: ['.git', '.gitignore', '.ipynb_checkpoints', '.mypy_cache', 'Archive', 'Files'] As you can see, os.listdir returns a list of strings, with each string being a filename. Of course, in UNIX-type systems, directories are files too—so along with files, you'll also see subdirectories without any obvious indication of which is which. I gave up on os.listdir long ago, in favor of glob.glob, which means the "glob" function in the "glob" module. Command-line users are used to using "globbing", although they often don't know its name. Globbing means using the * and ? characters, among others, for more flexible matching of filenames. Although os.listdir can return the list of files in a directory, it cannot filter them. You can though with glob.glob: Go to Full Article

FormBuilder in Angular 6

2018-11-13 10:04:02

As a follow-up to my "New Application Journey" article, I wanted to focus on how FormBuilder in Angular improves the process of form-based aspects of your application, while introducing some reactive programming concepts along the way. Recap As a TL;DR (too long, didn't read) to the original article, I wasn't happy with the application my mother-in-law was using for her very small business in the southeast section of the United States. So, I used her business needs to create a new application from scratch using Angular, MySQL, and the AWS environment. Since the application had a few forms to introduce, I was dreading the dated process I have been using — going all the way back to my introduction to AngularJS back in 2013.

Wrap GObjects in Python

2018-11-13 08:24:18

Python is a wonderful language for coding graphical interfaces. Thanks to the speed at which working code can be written and the lack of a time-consuming compile cycle, interfaces can be up and running in minutes and usable not long after that. Couple this with Python's ability to easily link to native libraries, and an excellent environment emerges. Learning how to wrap GTK+ C modules for use in Python will enable you to use a C-coded GObject in Python whenever you like, whether or not you[he]apos[/he]re especially proficient in C.

How to Develop a Web Application Compatible With Internet Explorer 11

2018-11-13 06:06:03

Developing web pages compatible with Internet Explorer can be tough at times. Even though Internet Explorer’s support was pulled back by Microsoft, it still remains a popular choice among users. Internet Explorer misbehaves with some of the most important components of HTML, be it low-height, margin, or padding. To achieve a proper fix to this problem, developers can use conditional comments and CSS commands to target browser specific commands. While it is practically impossible to achieve 100% compatibility for Internet Explorer due to its discontinued support and compatibility issues, there are several feasible ways to make sure that the user receives a decent experience. Although there is no way to develop perfectly compatible web pages, here’s a guide on how to develop a web application compatible with Internet Explorer 11 and its other variants. 

Basics of Spring AOP

2018-11-13 05:01:01

What Is AOP? AOP (Aspect-Oriented Programming) is a way of programming that helps increase modularity and avoid strong coupling of code by separating cross-cutting concerns. Additionally, it is one of the key components of the Spring Framework. A cross-cutting concern is code logic, which is scattered throughout the application. It affects the entire application. Transaction management and logging are the best examples of cross-cutting concerns.

Should Comcast Be Investigated For Antitrust Violations?

2018-11-13 01:25:00

The American Cable Association (ACA), an industry group that represents over 700 small and medium-sized cable operators, wants antitrust regulators to investigate whether Comcast-NBCUniversal is abusing its power to hurt smaller television and internet service providers. The group has "asked U.S. Assistant Attorney General Makan Delrahim to 'immediately' open an investigation into Comcast's practices," reports The Verge. Comcast is denying the claims, and while the Justice Department hasn't publicly responded, that may change soon. President Donald Trump tweeted about the ACA's claims earlier this afternoon. From the report: The ACA claims Comcast has a uniquely powerful hold on the U.S. cable industry because it controls a large chunk of "must have" programming like NBC's regional sports channels. The group argues that the Comcast "has shown a willingness to harm rivals" in the past, even while bound by a 2011 consent decree that expired earlier this year. The letter is dated November 6th but was published today, after Fox Business Networks reported on its existence last week. Contra Trump's description, the letter doesn't seem to describe "routine" violations of antitrust law. It's primarily arguing that there's a huge risk of Comcast abusing its market position, while explaining just how much damage could result if Comcast did so. The ACA has put forward more concrete claims in the past, though -- like a 2017 complaint that Comcast was forcing smaller cable providers to bundle unwanted NBC-owned channels into TV packages, driving up their costs. The ACA's letter also raises concerns involving Hulu, suggesting that Comcast could effectively hold the service hostage. "We have heard from ACA members that they fear that ComcastNBCU may restrict, if it is not already restricting, their ability to access Hulu and make it available to their customers as an alternative to their cable offerings," reads the letter.

Ad-Hoc YAML DSLs and Productivity

2018-11-12 19:01:01

One of my frustrations with the DevOps and cloud infrastructure tools is that most of them are badly designed DSLs that eschew all features of modern programming languages. Things like modules, data structures, functions, imperative control flow constructs, debuggers, linters, standard versioning/deployment practices, and rich library ecosystems are all missing. Of course, it is hard to do any real work without these features so the folks using these tools at some point come to the same conclusion and re-invent non-standard analogs to get by. The re-invention usually ends up being some kind of templating system built with a real language. Two obvious examples I can think of are Ansible with its Jinja templating and Terraform with its own ad-hoc variable interpolation mechanism that I presume is built on top of Go's templating features. Oh and I almost forgot Kubernetes and Helm. The arguments the tool designers bring up for why they made yet another DSL are usually some variation of "YAML or FooBarLang is declarative and so it reduces complexity". On the surface, this seems to make sense because declarative solutions, in theory, reduce complexity by hiding more details but when you start actually trying to solve problems the shortcomings become obvious. When real-world use cases are brought up along with the shortcomings of the tool to address them the response ends up being some variation of "You're using the tool wrong". Again, this kinda makes sense until you dig deeper and realize that it's not really an answer. Tools must always be subordinate to human intentions. If a tool can not accomplish a goal or requires extraordinary workarounds then it's not the user's fault and the logical conclusion is that the tool is badly designed.
