  • The 20 Best PHP Frameworks for Modern Developers in 2020

    Programming languages encompass the tech world, and we, living in the 21st century, are seeing a historical change. As we all know, these languages are widely used for developing various apps, mobile phone system, etc. and thereby, the demand for these is increasing rapidly over time among developers. Among the different scripting dialects, the language which has secured practically 80% of the site market and tech world is PHP. PHP is utilized to fabricate sites and web applications. The use of PHP frameworks improves the intricate procedure of development by giving a stage where the engineers can work without much of a stretch form PHP applications in the briefest time conceivable.

  • A new hash algorithm for Git

    The Git source-code management system is famously built on the SHA‑1 hashing algorithm, which has become an increasingly weak foundation over the years. SHA‑1 is now considered to be broken and, despite the fact that it does not yet seem to be so broken that it could be used to compromise Git repositories, users are increasingly worried about its security. The good news is that work on moving Git past SHA‑1 has been underway for some time, and is slowly coming to fruition; there is a version of the code that can be looked at now.

  • Git commit reordering

    While I was working for a presentation for kid’s school at Magnetic field, Aurora, Lunar Phases and Rockets, I added 4 big videos to the presentation (as I was going to use them offline while presenting).

    I know what git is not the place for big binary files, and even Github proposed to use the LFS backend for that, but as it was just temporary, I went ahead.

    After that commit, I also wrote two more articles, the one on Lego Speed Champions and the one on Galleria.io and PhotoSwipe, so it became a problem to have big files in between, when my plan was to remove them in the end.

  • OpenBLAS 0.3.8 Brings More AVX2/AVX512 Kernels, Other Optimizations

    For those using OpenBLAS as your BLAS (Basic Linear Algebra Subprograms) implementation, OpenBLAS 0.3.8 was released this weekend and coming with it are more AVX2/AVX-512 kernels and other optimizations.

    OpenBLAS continues striving to compete with Intel's MKL and other optimized BLAS implementations and with more AVX2 and AVX-512 should help with the performance on the latest Intel and AMD CPUs. There is now an AVX-512 DGEMM kernel, the AVX-512 SGEMM kernel was "significantly" improved, and new AVX-512 optimized kernels for CGEMM and ZGEMM. On the AVX2 front the kernels for STRMM, SGEMM, and CGEMM are said to have been significantly sped-up along with new kernels for CGEMM3M and ZGEMM3M.

  • Egad not more PAWs posts Sad

    Well back on my PAWS run again. This one might be a rather short series as I am really just looking at one Action in the Kinesis API 'SubscribeToShard'. There is an open bug for this one up on github https://github.com/pplu/aws-sdk-perl/issues/371 and one I think I can fix up fairly eaisy.

    First things first, a little word on Kinesis. Well in short it touted as a very scalable real time data-stream thingy that sings dances and basically makes you line much better. Myself I do not havea use for it but it is part of the system and there is a bug so in I go.

    I first had to set things up on the AWS server side with some permission etc the usualal srtuff I also had to run a number of command top build up my Kineses system to a point where I can actually use the 'SubscribeToShard'

  • Important Changes in YAML::PP v0.019

    During the SUSE Hackweek 19 I found time to fix some bugs and make important changes in YAML::PP.

    Some of these changes might break code, but I expect this will be rare.

    As I see more and more CPAN modules using YAML::PP, I decided to make these changes as soon as possible.

    I will explain all changes and the reasons.

  • Introducing KBOS

    Starting even before Moose, we (in the Perl 5 world) have a plethora of Modules extending the syntax of the language with Perl 6 and more in mind. The following article sums up not only my 2 and a half cents on the subject but also an attempt to implement it. It should be of interest to anybody thinking about programming in general.

    As many here know, Kephra is the project closest to my heart and during the latest iteration, I decided to extend the language itself to get a more expressive, less repetitive code base. I want a fast, extendable type system with helpful error messages, real private attributes, real private methods, signatures with typed, positional, named and optional arguments, relaxed professional error handling, I want to know all instances of a class, reuse by delegation and incorporate any foreign objects. Last not least should the system support me in marshalling all attributes, so I can fully restore a program state after restart or switch into a remote session / other window.

    The Kephra Base Object System (KBOS - read: ok boss) is designed to deliver on all that and I just want to discuss here my decisions. Some seem to be strange, like no inheritance (a feature), class types (not even Raku has them) or 4 different method scopes. But hej its my pile of garbage, stay away. I want this to become the optimal object system for Kephra's needs. It is not clear to me if I will release it or parts as a separate distribution in future.

  • Postponing some feature removals in Python 3.9

    Python 2 was officially "retired" on the last day of 2019, so no bugs will be fixed or changes made in that version of the language, at least by the core developers—distributions and others will continue for some time to come. But there are lots of Python projects that still support Python 2.7 and may not be ready for an immediate clean break. Some changes that were made for the upcoming Python 3.9 release (which is currently scheduled for October) are causing headaches because support for long-deprecated 2.7-compatibility features is being dropped. That led to a discussion on the python-dev mailing list about postponing those changes to give a bit more time to projects that want to drop Python 2.7 support soon, but not immediately.

    There will actually be one final release of Python 2, Python 2.7.18, in April. It is something of a celebratory release that will be made in conjunction with PyCon. There were some fixes that accumulated in the branch between the 2.7.17 release in October and the end of the year, so those fixes will be flushed and the branch retired. Other than the release itself, no other changes will be allowed for that branch in 2020.

  • How to Find Cheap Linux VPS? [Ed: Potentially a bit spammy (the links in there)]

    VPS stands for a Virtual Private Server. This is a virtual machine that is commonly used for hosting a web site. You can buy a VPS from a hosting provider companies such as Routerhosting, and based on your requirements. Each VPS provides you a private resource on a server to host your website. Likewise, you can use a shared VPS that is more affordable but in low security. Another noticeable factor for selecting a perfect VPS is operating system. The operating system that you select for VPS will have a strong impact on your business or the field of your action. There are two options available including Windows VPS and Linux VPS. Although there are many basic functions that are common between them, but selecting the OS completely depends on users and their preferences. As you know Linux VPS is more popular than Windows. You can easily find a cheap Linux VPS with great speed, function, and security.

  • 4 ways to identify your current shell (if it’s bash)

    Knowing which run you are using on your system is an important piece of information. Your shell determines your login environment to a large extent as it controls which environment variables get exported, your shell prompt etc. On a Linux system it’s almost certain that you will using the bash shell unless the system administrator has deliberately changed it to something else. In this quick article we will demonstrate four ways you can determines if you are running the bash shell or not.

  • Alan Pope: The Black Oblong of Monospace Mystery

    I originally titled this post “Don’t be afraid of the command line”, but decided “Black Oblong of Monospace Mystery” was more fun. Is the command line really scary? It doesn’t feel like that to me, but I grew up with an interface which looks like this on first boot.

  • What Is DNS Server?

    What is DNS Server? DNS stands for Domain Name System. This is actually a service that runs on all of our computers but majorly it runs the entire internet. We type a website in the browser and with the bling of our eyes the website is open. Have you ever wondered how does that happen? In today’s article, we will learn the process of how the website opens so fast and how DNS plays an important role in this process. We already know that every website is saved in a server that is located somewhere in the world. We need to reach this server and ask for the website homepage. In order to reach this Server, we need the address. When we want to visit a person in real life, we need his home address but in the world of the internet, we need the logical address. Internet Protocol, also known as IP Address is the logical addressing system. In order to reach a website we need to enter its server IP in the browser and the server will reply with the homepage. Initially, when the internet was in its infancy, people kept the record of IP addresses. Gradually, the internet because huge, and keeping the record of IP addresses was a challenge. The markers of the Internet knew that humans are very good at remembering names than numbers. They came up with the idea of a DNS Server.

  • How to Install AppImage in Linux

    AppImage is format for packaging applications which is self-contained. It is the universal software package format compatible with various Linux distribution. In the traditional system of installing software packages, you need to download, extract and install on various directories of the system. But with the AppImage there is no extraction, no installation, no root permission, you just download the single package, make it executable and run it with a single click. It includes all the compressed image, dependencies, and libraries needed to run the software. Even to uninstall the application, you will just remove the AppImage file.
