Daniel Stenberg: tiny-curl 7.72.0 – Micrium

Filed under
Software

You remember my tiny-curl effort to port libcurl to more Real-time operating systems? Back in May 2020 I announced it in association with me porting tiny-curl to FreeRTOS.

Today I’m happy to bring you the news that tiny-curl 7.72.0 was just released. Now it also builds and runs fine on the Micrium OS.

Timed with this release, I changed the tiny-curl version number to use the same as the curl release on which this is based on, and I’ve created a new dedicated section on the curl web site for tiny-curl:

Linux
Software

One of the key responsibilities of a system administrator is to ensure the safety of an organization’s computer data. This is a critical task for any organization, given that the loss of important data could have profound implications on its future prosperity.

There are a number of different strategies that a system administrator will need to use to ensure that data is preserved. For example, the person will need to maintain the computer system and/or network, by applying operating system updates and patches, by performing regular backups, and ensuring that the system is kept secure at all times. Disk cloning is a highly popular method of performing comprehensive backups of the operating system, installed software, and an organization’s data with the minimum of effort.

Kubernetes 1.19: Accentuate the Paw-sitive

Filed under
Server
Software

Finally, we have arrived with Kubernetes 1.19, the second release for 2020, and by far the longest release cycle lasting 20 weeks in total. It consists of 33 enhancements: 12 enhancements are moving to stable, 18 enhancements in beta, and 13 enhancements in alpha.

The 1.19 release was quite different from a regular release due to COVID-19, the George Floyd protests, and several other global events that we experienced as a release team. Due to these events, we made the decision to adjust our timeline and allow the SIGs, Working Groups, and contributors more time to get things done. The extra time also allowed for people to take time to focus on their lives outside of the Kubernetes project, and ensure their mental wellbeing was in a good place.

Contributors are the heart of Kubernetes, not the other way around. The Kubernetes code of conduct asks that people be excellent to one another and despite the unrest in our world, we saw nothing but greatness and humility from the community.

  • Annie – video downloader built with Go

    We’ve written a fair few reviews of open source software that let you download videos from YouTube and other similar services without needing to fire up a web browser. We really admired two command-line tools — youtube-dl and You-Get. We also warmly endorsed two GUI tools Tartube, and DownZemAll!. The latter has a truly sublime interface.

    We’re big advocates of command-line tools, so it seems appropriate to put a third command-line downloader tool through the mangle.

    Annie is an open source video downloader. It supports sites like YouTube, Tumblr, Vimeo, Facebook, Twitter, Instagram, TikTok, and other sites (mostly Chinese) I’ve never used. The program is written in the Go programming language.

  • Latte Dock v0.10~ | Background Radius and Shadows

    After using Kirigami ShadowedRectangle to provide background with different radius it was time to play with background shadows. So now you can adjust the background shadow size if you want.

    Notice: There is a bug with Kirigami.ShadowedRectangle; if the shadow size is bigger from any of the background width or height, the produced shadow is vastly in size. This is why Latte protects from the case and limits the shadow size to never exceed the mentioned case; more info at kde_bug#425745

You can't get anything out of that thing. The only way you can get it out is if you put it in. And if you put it in, you can't get it out because the DAC is no good in the MacBook Pro. So you have to use an external DAC and do a bunch of stuff to make up for the problems that the MacBook Pro has because they're not aimed at quality. They're aimed at consumerism.

Announcing ASql – async Sql for Qt

Filed under
Development
KDE
Software

When developing Qt applications be it Desktop, Mobile or Web that need to talk directly with a database the use of QtSql is usually the best choice, it has many database drivers, comes ready on their installer, but has a blocking API, which means a query will block you GUI thread.

My Cutelyst Web projects also used QtSql, and for low traffic this isn’t a big issue because you are not freezing users GUI, but you are freezing the request queue instead.

One of the Cutelyst apps I developed this year has a very high traffic, and a side effect of blocking came in play, I’ve about 3k TVs connected via websockets, once a TV connects it does an authentication query, it takes ~17ms, now when there is an event PostgreSQL notifies the application which does some 20 other queries a little more expensive (~30ms) and send them to the TVs, this event also blocks the Cutelyst process.

In this blog post, we cover some of the basics you need to know before contributing your first line of code. [...] Now that you understand that basic gist of open source, let’s go a little deeper. While some open source projects are small developer tools that help you accomplish a single task, other open source projects are large, complicated pieces of software that have interconnected parts. In these larger projects, different teams or working groups focus on developing specific parts of the technology, collaborating on the technology, peer reviewing and testing the code, and contributing their changes to the core tech.

  • Build Smart on Kubernetes World Tour: Developers’ path to platform freedom

    Without a doubt, Kubernetes is one of hottest open tech projects today and has been so for many years now. The reason for its durable, not-so-secret success? It’s the ability to containerize code, which frees developers from the constraint of writing code for one platform only and instead gives you the freedom of write-once, deploy-anywhere development. And why is this important? Enterprises know that the fastest route to app modernization depends on the ability to develop solutions that protect current tech investments, which likely run across multiple cloud platforms on and off premises. In other words, success depends on your ability to build solutions once and deploy them across multiple hybrid cloud platforms. Yep, containers tech delivers all of that and more. With that baseline, I’m writing to let you know that when it comes to learning Kubernetes, the IBM Developer advocates team has you completely covered with the Build Smart on Kubernetes World Tour. Since we launched the World Tour back in the fall of 2019, the team has delivered literally hundreds of free hands-on workshops globally to teach developers about the power of Kubernetes. It’s all part of the IBM Developer Way, delivering on our sole mission to teach the world’s developers about open tech through hands-on workshops and supporting content such as blog posts, tutorials, and videos. With the recent launch of new content on the Build Smart on Kubernetes World Tour site, it feels like a good time to provide a quick virtual tour of all that the site offers. Visit the updated site to find more than just upcoming tour events, but also self-paced learning options. You can now choose whether you learn at your own pace by viewing recorded content, register for upcoming live events, or, even better, both. I’m going to review each section to show you the details.
