  • The Sprint

    Hi -)) haven’t posted for some time, because I was busy travelling and coding for the first half of the month. From Aug 5 to Aug 9, I went to the Krita Sprint in Deventer, Netherlands.

    According to Boud, I was the first person to arrive. My flight took a transit via Hong Kong where some flights were affected due to natural and social factors, but fortunately mine was not one of them. Upon arrival in Amsterdam I got a ticket for the Intercity to Deventer. Railway constructions made me take a transfer via Utrecht Centraal, but that was not a problem at all: the station has escalators going both up to the hall, and down to the platforms (in China you can only go to the hall by stairs or elevator (which is often crowded after you get off)). When I got out of Deventer Station, Boud immediately recognized me (how?!). It was early in the morning, and the street’s quietness was broken by the sound of me dragging my suitcase. Boud led me through Deventer’s crooked streets and alleys to his house.

    For the next two days people gradually arrived. I met my main mentor Dmitry (magician!) and his tiger, Sagoskatt, which I (and many others) have mistaken for a giraffe. He was even the voice actor for Sago. He had got quite a lot of insights into the code base (according to Boud, “80%”) and solved a number of bugs in Krita (but he said he introduced a lot of bugs, ha!). Also I met David Revoy (my favourite painter!), the author of Pepper and Carrot. And Tiar, our developer who started to work full-time on Krita this year; she had always been volunteering to support other Krita users and always on the IRC and Reddit. And two of other three GSoC students for the year: Blackbeard (just as his face) and Hellozee. Sh_zam could not come and lost communications due to political issues, which was really unfortunate (eh at least now he can be connected). It is feels so good to be able to see so many people in the community – they are so nice! And it is such an experience to hack in a basement church.

  • How UCLA Library preserves rare objects with open source

    The University of California, Los Angeles, (UCLA) Library houses a collection of millions of rare and unique objects, including materials dating from 3000 BCE, that could be damaged, destroyed, or otherwise threatened if they were displayed.

    To make these special collections widely available while keeping them secure, the UCLA Library has been modernizing its digital repository, which was established 15 years ago on now-outdated software.

  • Huawei mulls open-source chip design if US ban continues

    Huawei Technologies Co said Friday that it would consider using RISC-V, an open-source chip architecture, if the US government continues restricting its access to the latest technologies from the UK firm ARM Holdings for a long time.

    Xu Zhijun, rotating chairman of Huawei, said in an interview in Shenzhen, Guangdong province, that the company has already obtained the perpetual license to ARM's V8 architecture technology, so the US government ban does not affect its current launch schedule of chips.

    "If ARM's new technologies are not available in the future, we can also use RISC-V, an architecture which is open to all companies. The challenge is not insurmountable," Xu said.

  • From Spark To Airflow And Presto: Demystifying The Fast-Moving Cloud Data Stack

    Putting data to work starts with exploration, or inspecting data so that you know what you have to work with and its characteristics. Presto is excellent for exploring large, unstructured data sets because it uses storage efficiently, which keeps costs down, and it’s compatible with SQL, a language data analysts are familiar with. 

    Spark, on the other hand, is great for exploring data sets when programming is required, such as being able to manipulate data for use in data science or machine learning. It has good support for non-SQL interfaces.

  • Cantor and the support for Jupyter notebooks at the finish line

    Hello everyone! It's been almost three weeks since my last post and this is going to be my my final post in this blog. So, I want to summarize all my work done in this GSoC project. Just to remember again, the goal of the project was to add the support for Jupiter notebooks to Cantor. This format is widely used in the scientific and education areas, mostly by the application Jupyter, and there is a lot of content available on the internet in this format (for example, here). By adding the support of this format in Cantor we’ll allow Cantor users access this content. This is short description, if you more intersted, you can found more details in my proporsal.

    [...]

    This is all for the limitations, I think. Let's talk about future plans and perspectives. In my opinion, this project has reached its initial goals, is finished now and will only need maintenance and support in terms of bug fixing and adjustment to potential format changes in future.

    When talking more generally, this project is part of the current overall development activities in Cantor to improve the usability and the stability of the application and to extend the feature set in order to enable more workflows and to reach to a bigger audience with this. See 19.08 and 18.12 release announcements to read more about the developments in the recent releases of Cantor. Support of the Jupyter notebook format is a big step into this direction but this not all. We have already many other items in our backlog like for the UX improvements, plots integration improvements going into this direction. Some of this items will be addressed soon. Some of them are something for the next GSoC project next year maybe?

    I think, that's all for now. Thank you for reading this blog and thank you for your interest in my project. Working on this project was a very interesting and pleasant period of my life. I am happy that I had this opportunity and was able to contribute to KDE and especially to Cantor with the support of my mentor Alexander Semke.

  • My Open-Source Activities from January to August 2019

    Debian is a general-purpose Linux distribution that is widely used on the planet. I am a Debian Developer who works on packages related to Android SDK and the Java ecosystem.

    I started a new package in an attempt to build the Android framework android.jar using the upstream build systems involving Ninja, Soong and others. Since the beginning we have been writing our own (very simple) makefiles to build the binaries in AOSP because their build logic tends to be simple and straightforward, until we worked on android.jar. Building it requires digging in so much code that it became incredibly hard to maintain, which is why we still haven’t brought in any newer version since android-framework-23. This is problematic as developers can’t build any apps that target Android 7+.

    After a month of work, this package is finally done. After all its dependencies are packaged in the future, it will be good to upload. This is where the students of Google Summer of Code (GSoC) come in!

  • Dive into the life and legacy of Alan Turing: 5 books and more

    Another well-known fact about Turing was his conviction for "gross indecency" because of his homosexuality, and the posthumous apology and pardon issued over more a half a decade after Turing’s death.

    But beyond all of this, who was Alan Turing?

    Here are six books that delve deeply into the life and legacy of Alan Turing. Collectively, these books cover his life, both professional and personal, and work others have done to build upon Turing’s ideas. Individually, or collectively, these works allow the reader to learn who Alan Turing was beyond just a few well-known, broad-stroke themes.

    Go is a compiled, statically typed programming language that makes it easy to build simple, reliable, and efficient software. It’s a general purpose programming language with modern features, clean syntax and a robust well-documented common library, making it a good candidate to learn as your first programming language. While it borrows ideas from other languages such as Algol and C, it has a very different character. It’s sometimes described as a simple language.

    Go is an open source project developed by a team at Google and many contributors from the open source community. Go’s first release was in 2009, and it’s distributed under a BSD-style license.

    This article selects the best open source books that will give readers a firm foundation in developing Go applications.

It seems that the exception specified in the PEP for the operator may not really be the best choice, as a recent discussion hashed out.

  • Dirk Eddelbuettel: Rcpp now used by 1750 CRAN packages

    Since this morning, Rcpp stands at just over 1750 reverse-dependencies on CRAN. The graph on the left depicts the growth of Rcpp usage (as measured by Depends, Imports and LinkingTo, but excluding Suggests) over time.

    Rcpp was first released in November 2008. It probably cleared 50 packages around three years later in December 2011, 100 packages in January 2013, 200 packages in April 2014, and 300 packages in November 2014. It passed 400 packages in June 2015 (when I tweeted about it), 500 packages in late October 2015, 600 packages in March 2016, 700 packages last July 2016, 800 packages last October 2016, 900 packages early January 2017,
    1000 packages in April 2017, 1250 packages in November 2017, and 1500 packages in November 2018. The chart extends to the very beginning via manually compiled data from CRANberries and checked with crandb. The next part uses manually saved entries. The core (and by far largest) part of the data set was generated semi-automatically via a short script appending updates to a small file-based backend. A list of packages using Rcpp is availble too.

    Also displayed in the graph is the relative proportion of CRAN packages using Rcpp. The four per-cent hurdle was cleared just before useR! 2014 where I showed a similar graph (as two distinct graphs) in my invited talk. We passed five percent in December of 2014, six percent July of 2015, seven percent just before Christmas 2015, eight percent last summer, nine percent mid-December 2016, cracked ten percent in the summer of 2017 and eleven percent in 2018. We are currently at 11.83 percent: a little over one in nine packages. There is more detail in the chart: how CRAN seems to be pushing back more and removing more aggressively (which my CRANberries tracks but not in as much detail as it could), how the growth of Rcpp seems to be slowing somewhat outright and even more so as a proportion of CRAN – just like one would expect a growth curve to.

  • GSoC final report

    The idea of this GSoC project was to implement new Domain-Specific language for LibreOffice to be used in UI testing by logging the user interactions with LO applications then generate the python code needed for the python UI framework which asaswill make testing easier. Also, the project aims to improve the logger that logs all the user interaction to be logged in the new DSL syntax to be more readable. Then we can use this replaying all the user interactions as a UI test.

  • Day 88 [Ed: Karina Passos on her time in KDE GSoC]

    Today, I’ll talk about my GSoC experience and won’t focus so much on Khipu, even because i still have some things to do, so in the next days I’ll publish a post about Khipu and what I’ve done.

    As I said in the old posts, the begin was the most complicated part for me. I made a project thinking that I’d be able to complete, I started studying the code and the things I’d make many weeks before the start. But I couldn’t understand the code and I think it’s my fault. I even lost three weeks after the start stuck in this situation. It was hard for me, because I was really scared about failing and at the same time dealing with my college stuff, because in Brazil, our summer (and our summer vacation), is in December-February, in July we have a three week vacation, but GSoC lasts three months. I wasn’t having a good time at college as well, but with the help of my therapist and my mentors I found a way to deal with the both things and as everything went well.

    After this complicated start, to not fail, my mentor suggested that I could change my project. My initial project was to create new features to Khipu and Analitza (Khipu’s main library) to make it a better application and move it out from beta. Then, my new project was to refactor Khipu (using C++ and QML). I was scared because I didn’t know if I’d be able to complete it, but the simplicity of QML helped me a lot, and before the first evaluation (approx. two weeks after I decided my new project) I finished the interface, or at least most of it.

    [...]

    And, of course, I’d like to say to KDE, Google and my mentors: thanks for this opportunity.

  • Open Policy Agent: Cloud-native security and compliance

    Every product or service has a unique way of handling policy and authorization: who-can-do-what and what-can-do-what. In the cloud-native world, authorization and policy are more complex than ever before. As the cloud-native ecosystem evolves, there’s a growing need for DevOps and DevSecOps teams to identify and address security and compliance issues earlier in development and deployment cycles. Businesses need to release software on the order of minutes (instead of months). For this to happen, those security and compliance policies—which in the past were written in PDFs or email—need to be checked and enforced by machines. That way, every few minutes when software goes out the door, it’s obeying all of the necessary policies.

    This problem was at the top of our minds when Teemu Koponen, Torin Sandall, and I founded the Open Policy Agent project (OPA) as a practical solution for the critical security and policy challenges of the cloud-native ecosystem. As the list of OPA’s successful integrations grows—thanks to active involvement by the open source community—the time is right to re-introduce OPA and offer a look at how it addresses business and policy pain points in varied contexts.

  • Eirini: Mapping Code into Containers

    There has been a lot of noise recently about the Project known as Eirini.  I wanted to dig into what this project was in a little more detail.
    If you weren’t already aware, its goal is to allow Cloud Foundry to use any scheduler but it’s really for allowing the workloads to run directly inside Kubernetes without needing separately scheduled Diego cells to run on top of.
    There are many reason that this is a fantastic change, but the first and foremost is that having a scheduler run inside another scheduler is begging for headaches. It works, but there are odd edge cases that lead to split-brain decisions.
    NOTE: There is another project (Quarks) that is working on containerizing the control plane in a way that the entire platform is more portable and requiring significantly less overhead. (As in: you can run Kubernetes, the entire platform, and some work, all on your laptop)

    Busy trying to salvage footage from a recent video shoot, I missed the arrival of Kdenlive 19.08, the first major release of this free video editor since its big code revamp earlier this year.

    And what a release it is!

    Kdenlive 19.08 builds on the terrific work featured in the various point releases that have been available since April.

    “This version comes with a big amount of fixes and nifty new features which will lay the groundwork for the 3 point editing system planned for this cycle,” they say in their release announcement.

  • LabPlot's Welcome screen and Dataset feature in the finish line

    Hello Everyone! This year's GSoC is coming to its end. Therefore I think that I should let you know what's been done since my last blog post. I would also like to evaluate the progress I managed to make and the goals set up at the beginning of this project.

    As I told you in my last post, my main goal, in this last period, was to clean up, properly document, refactor, optimise the code and make it easier to read, so it would be fit to be brought to the master branch and to be used by the community.

    My next proposition was to search for bugs and fix them, in order to make the implemented features more or less flawless. I can happily state, that I succeeded in this.

  • Distributed Beta Testing Platforms

    Do they exist? Especially as free software? I don’t actually know, but I’ve never seen a free software project use something like what I’ve got in mind.

    That would be: a website where we could add any number of test scenarios.

    People who wanted to help would get an account, make a profile with their hardware and OS listed. And then a couple of weeks before we make a release, we’d release a beta, and the beta testers would login and get randomly one of the test scenarios to test and report on. We’d match the tests to OS and hardware, and for some tests, probably try to get the test executed by multiple testers.

    Frequent participation would lead to badges or something playful like that, they would be able to browse tests, add comments and interact — and we, as developers, we’d get feedback. So many tests executed, so many reported failure or regressions, and we’d be able to improve before the release.

    The branch point also meant that the Change Code Complete deadline was passed. As part of the Go SIG, I was one of the packagers behind the Adopt new Go Packaging Guidelines Change. As mentioned in the last post, this was mostly handled by @eclipseo and the tracker bug was marked complete for it just earlier. I am also behind the Automatic R runtime dependencies Change. As part of this Change, I initiated a mini-rebuild last week of all affected R packages. I will write about that in a separate post. That tracker bug is now Code Complete, though there are a couple FTBFS to fix up.

    With release monitoring working again, that meant a slew of new bug reports about new package versions being available. This happened just last Friday, so I haven’t had much chance to update everything. I did manage to go through almost all the R packages, except for a few with new dependencies. I also updated one or two Go and Python packages as well.

  • 5 Reasons to Use a VM for Development [Ed: Dice promoting the idea that developers should use Windows and keep GNU/Linux in a VM jail using Microsoft's proprietary tools]

    I started using virtual machines (VMs) on my development PC about six years ago; I was keen to learn Linux, having been a Windows developer since the mid-1990s. At first, I used an old Windows PC and installed a Linux distro on it; but I quickly found out that the distro took up a lot of space, and I needed a KVM switch to manage two different PCs. It was all a bit “fiddly,” which is why I began exploring the potential of VMs.

    Discovering VirtualBox was a godsend, and made things a lot more convenient. Despite all the flak Oracle gets over its databases, MySQL, and Java, Virtual Box remains an excellent and free open-source package.

    If you are planning on attending either conference, make sure to stop by our booth to see what our team has been working on! This year, we'll be showcasing how Panfrost, the open source driver for Arm Mali GPUs, turns a RK3399 SoC (in this case, the versatile ROCK Pi 4), into a very attractive platform to try out Wayland on ARM devices.

  • Amazon DocumentDB Speeds Up With Slow Queries Logging

    Amazon continues to add extra supports to its non-relational database store DocumentDB with the addition of slow queries logging.

    Slow queries logging allows user to monitor their slowest queries in the cluster. This helps to improve overall performance of the cluster and the individual query.

    Once the user has enabled a set profiler for the query the system will monitor operations and if any queries run longer than the customer-defined threshold, set at 100ms by default, the system will log their execution time and send an alert to the CloudWatch Logs.

  • GNOME 3.34 Works Out Refined XWayland Support For X11 Apps Run Under Sudo

    GNOME 3.34 continues to look like an incredibly great release in the performance department as well as for Wayland users.

    Earlier this summer, support was added to GNOME's Mutter to generate an Xauth file and passing it to XWayland when starting. The focus of that Red Hat contribution was for allowing X.Org/X11 applications to be run under XWayland as sudo. Up to this point when using sudo with an X11 app on Wayland, it hasn't worked out but this addition for GNOME 3.34 corrects that behavior.

  • RADV Vulkan Driver Lands Renoir APU Support In Time For Mesa 19.2

    Just hours ahead of the Mesa 19.2 feature freeze and days after the RadeonSI OpenGL driver added Renoir support, the RADV Vulkan driver has picked up support for this next-gen Zen 2 + Vega APU.

    The support comes down to just eight lines of new code for this new APU rumored to be launching in 2020. While it was hoped that this would be the first APU built on the Zen 2 CPU microarchitecture and with Navi graphics, the open-source Linux driver code drops have all pointed it to be more of a Raven/Vega refresh on the graphics side.

  • Intel Icelake Thunderbolt Support Still Being Squared Away For Linux - Hopefully For 5.4

    Intel Icelake laptops will soon be hitting store shelves and a vast majority of the Linux support has been squared away for many months. Unfortunately one bit still not mainlined is the Thunderbolt support.

    Back in July we wrote about the Icelake Thunderbolt support still not merged yet while Icelake's Gen11 graphics and other new processor features have all been squared away for several kernel releases in ensuring good launch-day support. With Icelake, the Thunderbolt functionality has moved onto the SoC itself (sans the Thunderbolt power delivery) and that's taken additional time for getting the Linux kernel support in order.

  • OBS Studio 24.0 Will Let You Pause While Recording, Other New Options

  • Kontact and Google Integration Issues

    Lately there were some issues with the Google integration in Kontact which caused that it is no longer possible to add new Google Calendar or Gmail account in Kontact because the log in process will fail. This is due to an oversight on our side which lead to Google blocking Kontact as it did not comply with Google’s policies. We are working on resolving the situation, but it will take a little bit.

    Existing users should not be affected by this - if you already had Google Calendar or Gmail set up in Kontact, the sync should continue to work. It is only new accounts that cannot be created.

    In case of Gmail the problem can mostly be worked around when setting up the IMAP account in KMail by selecting PLAIN authentication1 method in the Advanced tab and using your email and password. You may need to enable Less Secure Applications in your Google account settings in order to be able to log in with regular email address and password.

  • Kevin Fenzi: Flock 2019

    Flock time is upon is! This time in lovely Budapest. As always when flock is in europe, it’s a long flight for me, but otherwise travel was uneventfull: Drive 2 hours to PDX, then PDX to AMS, then a short layover for coffee and stoupwaffles and then AMS to BUD, and finally a taxi ride to the hotel.

    The hotel is quite lovely. It’s right next to the danube river and has a nice view. The AC is working nicely too (it’s quite hot outside here right now). After getting into the hotel yesterday and a quick dinner at a very nice place down the road, I managed to sleep for 10+ hours.

  • KNOB attack: Is my Bluetooth device insecure?

    A recent attack against Bluetooth, called KNOB, has been making waves last week. In essence, it allows an attacker to downgrade the security of a Bluetooth so much that it's possible for the attacker to break the encryption key and spy on all the traffic. The attack is so devastating that some have described it as the "stop using bluetooth" flaw.

    This is my attempt at answering my own lingering questions about "can I still use Bluetooth now?" Disclaimer: I'm not an expert in Bluetooth at all, and just base this analysis on my own (limited) knowledge of the protocol, and some articles (including the paper) I read on the topic.

  • Dear sysadmins: Patch Webmin now – zero-day exploit emerges for potential hijack hole in server control panel

    The bug appears to have been revealed on Saturday, August 10, by Özkan Mustafa Akkuş at DEF CON and to have been made available as an exploit in a module for the Metasploit framework. The Webmin maintainers didn't hear about it until Saturday, August 17, when they noticed people discussing the issue on Twitter and Reddit. The CVE was created Thursday, August 15.

    Webmin has about 215,000 installations, according to a Shodan search (account required), and about 13,000 instances of the particularly vulnerable version 1.890.

    [...]

    According to Cooper, the malicious code was introduced into Webmin and Usermin through the project's build infrastructure. "We're still investigating how and when, but the exploitable code has never existed in our GitHub repositories, so we've rebuilt from git source on new infrastructure," he said.

    In an email to The Register, Cooper said the malicious code – which appeared in the Sourceforge repo but not the GitHub repo – was introduced to Webmin on local package build infrastructure before it reached Sourceforge.

  • Warfork Letting Warsow Live On Under Steam

    Going back a decade one of the interesting open-source FPS games of its time was Warsow. Development on Warsow has seemingly been tremulous over the past few years (edit: though the core developer has recently released a new beta) for this Qfusion (Quake 2 code base) engine powered game that started in 2005, but now there is Warfork as a fork of Warsow that is being developed and also available via Steam. 

    Hitting Steam this past week was the release of Warfork for Windows, macOS, and Linux. The game is free to play and with it going up on Steam will hopefully attract new gamers to this shooter title who may not be otherwise following the open-source scene. 

  • KDE sprints in summer heat

    It was great to see many new faces at the Plasma sprint. Most of these new contributors were working on the Plasma and KDE Apps Ui and Ux and we definitely need some new blood in these areas. KDE's Visual Design Group, the VDG, thinned out over the last two years because some leading figures left. But now seeing new talented and motivated people joining as designers and Ux experts I am optimistic that there will be a revival of the golden time of the VDG that brought us Breeze and Plasma 5.

    In regards to technical topics there is always a wide field of different challenges and technologies to combine at a Plasma sprint. From my side I wanted to discuss current topics in KWin but of course not everyone at the sprint is directly working on KWin and some topics require deeper technical knowledge about it. Still there were some fruitful discussions, of course in particular with David, who was the second KWin core contributor present besides me.

    As a direct product of the sprint my work on dma-buf support in KWin and KWayland can be counted. I started work on that at the sprint mostly because it was a feature requested already for quite a long time by Plasma Mobile developers who need it on some of their devices to get them to work. But this should in general improve in our Wayland session the performance and energy consumption on many devices. Like always such larger features need time so I was not able to finish them at the sprint. But last week I landed them.

DragonFlyBSD Pulls In AMD Radeon Graphics Code From Linux The 4.7 Kernel

It was just last month that DragonFlyBSD pulled in Radeon's Linux 4.4 kernel driver code as an upgrade from the Linux 3.19 era code they had been using for their open-source AMD graphics support. This week that's now up to a Linux 4.7 era port. François Tigeot who continues doing amazing work on pulling in updates to DragonFlyBSD's graphics driver now upgraded the Radeon DRM code to match that of what is found in the upstream Linux 4.7.10 kernel.

TenFourFox FPR16b1 available

FPR16 got delayed because I really tried very hard to make some progress on our two biggest JavaScript deficiencies, the infamous issues 521 (async and await) and 533 (this is undefined). Unfortunately, not only did I make little progress on either, but the speculative fix I tried for issue 533 turned out to be the patch that unsettled the optimized build and had to be backed out. There is some partial work on issue 521, though, including a fully working parser patch. The problem is plumbing this into the browser runtime which is ripe for all kinds of regressions and is not currently implemented (instead, for compatibility, async functions get turned into a bytecode of null throw null return, essentially making any call to an async function throw an exception because it wouldn't have worked in the first place). This wouldn't seem very useful except that effectively what the whole shebang does is convert a compile-time error into a runtime warning, such that other functions that previously might not have been able to load because of the error can now be parsed and hopefully run. With luck this should improve the functionality of sites using these functions even if everything still doesn't fully work, as a down payment hopefully on a future implementation. It may not be technically possible but it's a start. Read more
