  • Intervalometerator: Open Source Code for a Remote Timelapse DSLR

    Want to set up a remote DSLR for shooting a time-lapse? The Intervalometerator (AKA ‘intvlm8r’) is an open-source intervalometer that can help you do so at minimal hardware cost (as long as you’re comfortable tinkering with hardware and software).

    Created by Sydney-based coder Greig Sheridan and his photographer partner Rocky over the course of a year, the Intervalometerator is designed to be both cheap and easy to build with familiar tools and using Raspberry Pi and Arduino microcontrollers.

    “My partner and I have been working for over twelve months now on an intervalometer in order to shoot a DSLR-based time-lapse of the construction of our friends’ home in NZ,” Sheridan tells PetaPixel. “It was at the time a seemingly clever idea for a house-warming present, but it grew like tribbles to consume an incredible amount of effort).

  • Open Source Tools & Framework: Microservices Perspective

  • Agile and open source can complement each other

    Despite the growing popularity of both Agile development and open-source practices, it’s not often that they come up in the same conversation. When these two concepts do intersect, it’s often to highlight the contradicting viewpoints that these two models supposedly represent.

    While there are core differences, Agile doesn’t have to be the enemy of open source—in fact, I would argue the opposite.

  • SD Times Open-Source Project of the Week: Twilio CLI

    In an effort to help its developers be more productive, Twilio has announced the beta version of Twilio CLI. It is an open-source command line interface that enables developers to access Twilio through their command prompt.

    “It’s hard to beat the flexibility and power that a CLI provides at development time. Until now, there was no CLI designed for typical communications requirements,” Ashley Roach, the product manager for developer interfaces at Twilio, wrote in a post.

  • Using open source in your enterprise? What to look out for

    According to Statista, the open source market was valued at $11.4 billion in 2017 and is estimated to grow to $32.95 billion by 2022, showing it has no intention of slowing down anytime soon.

    Founded on the belief that collaboration and cooperation build better software, open source sounds closer to a utopian dream than to the cold digital world of programming. Research showed that open source code takes over proprietary one in applications at 57%. This has numerous benefits, such as speeding up the software development process or creating more effective and innovative software.

    For example, open source frontend development frameworks, such as Angular, are often found in custom web apps, which allows companies to get their products to market at ever-increasing rates. In addition, companies tend to engage open source when at the cusp of technological innovation, especially when it comes to AR, blockchain, IoT, and AI.

  • Open Source Technology: What's It All About?

    To understand how open source works, it is important to appreciate where it all began. The very idea behind its inception isn’t exactly a new one. It’s been adopted by scientists for decades. Let’s imagine a scientist working on a project to develop a cure for an illness. If this scientist only published the results and kept the methods a secret, this would undoubtedly inhibit scientific discovery and further research in this area. On the other hand, teaming up with other researchers and making results and methodologies visible allows for greater and faster innovation.

    This is the premise from which open source was originally born. Open source refers to software that has an open source code so it can be viewed, modified for a particular need, and importantly, shared (under license). One of the first well known open source initiatives was developed in 1998 by Netscape, which released its Navigator browser as free software and demonstrated the benefits of taking an open source approach. Since then, there have been a number of pivotal moments in open source history that have shaped the technology industry as we know it today. Nowadays, some of the latest technology you use on a daily basis, like your smartphone or laptop, will have been built using open source software.

    [...]

    Recent research found that 60 percent of organizations are already using open source software. Many businesses are realizing the benefits that the technology can bring in relation to driving innovation and reducing costs. This in turn is seeing a growing number of organizations integrate open source into their IT operations or even building entire businesses around it. With emerging technologies such as cloud, AI and machine learning only driving this adoption further, open source will continue to play a central and growing role throughout the technology landscape.

  • How to Take Your Open Source Project from Good to Great

    Whether or not you expect anyone to contribute to your project, you should be prepared for the possibility of others wanting to help your cause. And when that happens, your contributing guide will show those helpers exactly how they can get involved. This guide, usually in the form of a CONTRIBUTING.md file, should include information on how one should submit a pull request or open an issue for your project and what kinds of help you’re looking for (bug fixes, design direction, feature requests, etc.).

  • ForgeRock Delivers Open Source IoT Edge Controller for Device Identity

  • Exclusive: Automattic CEO Matt Mullenweg on what’s next for Tumblr

    It’s been a long and winding road for Tumblr, the blogging site that launched a thousand writing careers. It sold to Yahoo for $1.1 billion in 2013, then withered as Yahoo sold itself to AOL, AOL sold itself to Verizon, and Verizon realized it was a phone company after all. Through all that, the site’s fierce community hung on: it’s still Taylor Swift’s go-to social media platform, and fandoms of all kinds have homes there.

    Verizon sold Tumblr for a reported $3 million this week, a far cry from the billion-dollar valuation it once had. But to Verizon’s credit, it chose to sell Tumblr to Automattic, the company behind WordPress, the publishing platform that runs some 34 percent of the world’s websites. Automattic CEO Matt Mullenweg thinks the future of Tumblr is bright. He wants the platform to bring back the best of old-school blogging, reinvented for mobile and connected to Tumblr’s still-vibrant community, and he’s retaining all 200 Tumblr employees to build that future. It’s the most exciting vision for Tumblr in years.

    Matt joined Verge reporter Julia Alexander and me on a special Vergecast interview episode to chat about the deal, how it came together, what Automattic’s plans for Tumblr look like, and whether Tumblr might become an open-source project, like WordPress itself. (“That would be pretty cool,” said Matt.)

    Oh, and that porn ban.

  • uwsgi weirdness with --http

    Instead of upgrading everything on my server, I'm just starting from scratch. From Ubuntu 16.04 to Ubuntu 19.04 and I also upgraded everything else in sight. One of them was uwsgi. I copied various user config files but for uwsgi things didn't very well. On the old server I had uwsgi version 2.0.12-debian and on the new one 2.0.18-debian. The uWSGI changelog is pretty hard to read but I sure don't see any mention of this.

  • Wingware Blog: Viewing Arrays and Data Frames in Wing Pro 7

    Wing Pro 7 introduced an array and data frame viewer that can be used to inspect data objects in the debugger. Values are transferred to the IDE according to what portion of the data is visible on the screen, so working with large data sets won't slow down the IDE. The array viewer works with Pandas, numpy, sqlite3, xarray, Python's builtin lists, tuples, and dicts, and other classes that emulate lists, tuples, or dicts.

  • Solving Sequence Problems with LSTM in Keras: Part 2

    This is the second and final part of the two-part series of articles on solving sequence problems with LSTMs. In the part 1 of the series, I explained how to solve one-to-one and many-to-one sequence problems using LSTM. In this part, you will see how to solve one-to-many and many-to-many sequence problems via LSTM in Keras. Image captioning is a classic example of one-to-many sequence problems where you have a single image as input and you have to predict the image description in the form of a word sequence. Similarly, stock market prediction for the next X days, where input is the stock price of the previous Y days, is a classic example of many-to-many sequence problems. In this article you will see very basic examples of one-to-many and many-to-many problems. However, the concepts learned in this article will lay the foundation for solving advanced sequence problems, such as stock price prediction and automated image captioning that we will see in the upcoming articles.

  • Voronoi Mandalas

    I started with Carlos Focil's mandalapy code, modifying the parameters until I had a design I liked. I decided to make the Voronoi diagram show both points and vertices, and I gave it an equal aspect ratio. Carlos' mandalapy code is a port of Antonio Sánchez Chinchón's inspiring work drawing mandalas with R, using the deldir library to plot Voronoi tesselations.

One of the popular programming katas is called FizzBuzz. This is also a popular interview question for computer programmers.

  • why python is the best-suited programming language machine learning

    Machine Learning is the hottest trend in modern times. According to Forbes, Machine learning patents grew at a 34% rate between 2013 and 2017 and this is only set to increase in the future. And Python is the primary programming language used for much of the research and development in Machine Learning. So much so that Python is the top programming language for Machine Learning according to Github. Python is currently the most popular programming language for research and development in Machine Learning. But you don’t need to take my word for it! According to Google Trends, the interest in Python for Machine Learning has spiked to an all-new high with other ML languages such as R, Java, Scala, Julia, etc. lagging far behind.

  • Node.js now available in Haiku

    As some have already known for a long time, many platforms have had support for writing software in JavaScript or TypeScript with the help of the Node.js runtime and over the years, much of the software written by developers these days have gradually been written in either of those languages. However, Haiku has lacked a Node.js port for quite sometime and it wasn’t possible to run or develop JavaScript based software or libraries that depended on the Node.js runtime. Now I can say that Node.js is available for Haiku and can be downloaded from HaikuDepot on 64 bit (32 bit support is being worked on). The version which is currently available is 12.3.1 and is already being updated to the latest version at the time of this writing to 12.10.0 and support for the upcoming LTS version is also coming to HaikuPorts. Several patches have been upstreamed by members of the HaikuPorts team to projects such as libuv (cross-platform async I/O library), GN, etc and we hope to upstream to larger projects like V8 (Google’s JavaScript engine used in Chromium and QtWebEngine) and the Node.js project, which will ease the bringup of a future Node LTS release for Haiku.

  • LLVM 9.0 Released With Ability To Build The Linux x86_64 Kernel, Experimental OpenCL C++

    It's coming almost one month behind schedule, but LLVM 9.0 is out today along with the Clang 9.0 C/C++ compiler and associated sub-projects for this open-source compiler infrastructure. LLVM 9.0 is an exciting release with bringing the ability to build the mainline Linux x86_64 kernel using LLVM/Clang 9.0 now that "asm goto" support was finally added. The AArch64 support was in better standing previously but now at long last the mainline Clang 9.0 compiler can build the current Linux kernel releases with not needing any extra patches on either side, just point the kernel build CC to Clang.

Linux 5.4 Development, PRs, Merges

  • BLK-IOCOST Merged For Linux 5.4 To Better Account For Cost Of I/O Workloads

    BLK-IOCOST is a new I/O controller by veteran kernel developer Tejun Heo that is a work-conserving proportional controller. He goes over blk-iocost in great detail in one of the earlier patch series, "It currently has a simple linear cost model builtin where each IO is classified as sequential or random and given a base cost accordingly and additional size-proportional cost is added on top. Each IO is given a cost based on the model and the controller issues IOs for each cgroup according to their hierarchical weight. By default, the controller adapts its overall IO rate so that it doesn't build up buffer bloat in the request_queue layer, which guarantees that the controller doesn't lose significant amount of total work...The controller provides extra QoS control knobs which allow tightening control feedback loop as necessary." See that aforelinked article for more details and results.

  • Btrfs & XFS File-Systems See More Fixes With Linux 5.4

    The mature XFS and Btrfs file-systems continue seeing more fixes and cleaning with the now in-development Linux 5.4 kernel. On the Btrfs front the Linux 5.4 changes are summed up as "work on code refactoring, sanity checks and space handling. There are some less user visible changes, nothing that would particularly stand out." The Btrfs changes include deprecating a few items as well as improving the exposure of debugging information via sysfs. See the pull request for all the Btrfs file-system fixes and changes this round.

  • Attention: Fedora Yahoo Email Users

    Going from a blast of the past we are currently going through one of the Yahoo is not allowing many emails with either fedoraproject.org OR from our mail routers. It would seem that the way to get yahoo to blacklist a domain is to get subscribed to mailing lists and then report the lists as SPAM. Enough accounts (or maybe if one person does it enough times).. yahoo will helpfully blacklist the domain completely. [It then is usually a multi-month process of people explaining that no Fedora is not a spam site, hasn't been taken over by a spam site, or a bunch of other things which do happen so any mail admin is going to be wary on.]
