[...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack.

    Burr Sutter gave a terrific talk in India in July, where he laid out the terms, systems and processes needed to setup Kubernetes for developers. This is an introductory presentation, which may be useful for your larger community of Kubernetes users once you’ve already setup User Provisioned Infrastructure (UPI) in Red Hat OpenShift for them, though it does go into the deeper details of actually running the a cluster. To follow along, Burr created an accompanying GitHub repository, so you too can learn how to setup an awesome Kubernetes cluster in just 9 steps.

OpenZFS Could Soon See Much Better Deduplication Support

Filed under
Linux

This is good news for OpenZFS performance assuming the dedup support is punctually opened up and is an acceptable state for quickly landing in this ZFS file-system code used by Linux with "ZFS On Linux" and in the process of by the likes of FreeBSD.

The ZFS file-system has supported data deduplication for the past decade. However, it's not widely recommended due to being very heavy on RAM usage as well as relatively taxing on the CPU, so it will be interesting to see just how effective is the Panzura implementation.

  • 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.

  • 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.

  • Node.js Brought To BeOS-Inspired Haiku Open-Source OS

    Haiku as the open-source operating system that still maintains BeOS compatibility continues tacking on modern features and support for software well past the days of BeOS.

    The newest major piece of software working on BeOS is Node.js, including support for its NPM package manager.

  • 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.

  • 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

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.

    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.]

German ministry hellbent on taking back control of 'digital sovereignty', cutting dependency on Microsoft

Filed under
Microsoft

The Federal Ministry of the Interior (Bundesministerium des Innern or BMI) in Germany says it will reduce reliance on specific IT suppliers, especially Microsoft, in order to strengthen its "digital sovereignty".

In an official statement, the Federal Minister of the Interior Horst Seehofer states that “in order to ensure our digital sovereignty, we want to reduce dependencies on individual IT providers. We are also considering alternative programs to replace certain software. This will be done in close coordination with other EU countries.”

BMI commissioned a strategic market analysis from consultants PwC, resulting in a paper that was published last month. The paper examines the risks inherent in IT dependency on commercial software vendors, with a particular focus on Microsoft because of the heavy use of its products and the way they are interconnected, especially Microsoft Office, Windows, Windows Server and Office 365.

  • Praise Be CUPS Driverless Printing

    Last Tuesday, I finally got to start updating $work's many desktop computers to Debian Buster. I use Puppet to manage them remotely, so major upgrades basically mean reinstalling machines from scratch and running Puppet.

    Over the years, the main upgrade hurdle has always been making our very large and very complicated printers work on Debian. Unsurprisingly, the blog posts I have written on that topic are very popular and get me a few 'thank you' emails per month.

    I'm very happy to say, thanks to CUPS Driverless Printing (CUPS 2.2.2+), all those trials and tribulations are finally over. Printing on Buster just works. Yes yes, even color booklets printed on 11x17 paper folded in 3 stapled in the middle.

    mailman2 is pretty great. You can get a dump of an email list pretty easily and mailman3's web frontend, the lovely hyperkitty, is well, lovely. Importing a legacy mailman2 mbox went without a hitch thanks to the awesome hyperkitty_import importer. Kudos to the Debian Mailman Team for packaging this in Debian for us.

    But what about cramming a Yahoo! Group mailing list in hyperkitty? I wouldn't recommend it. After way too many hours spent battling character encoding errors I just decided people that wanted to read obscure emails from 2003 would have to deal with broken accents and shit. But hey, it kinda works!

    Oh, and yes, archiving a Yahoo! Group with an old borken Perl script wasn't an easy task. Hell, I kept getting blacklisted by Yahoo! for scraping too much data to their liking. I ended up patching together the results of multiple runs over a few weeks to get the full mbox and attachments.

    By the way, if anyone knows how to tell hyperkitty to stop at a certain year (i.e. not display links for 2019 when the list stopped in 2006), please ping me.

Running The AMD "ABBA" Ryzen 3000 Boost Fix Under Linux With 140 Tests

Filed under
Graphics/Benchmarks

Last week AMD's AGESA "ABBA" update began shipping with a fix to how the boost clock frequencies are handled in hopes of better achieving the rated boost frequencies for Ryzen 3000 series processors. I've been running some tests of an updated ASUS BIOS with this adjusted boost clock behavior to see how it performs under Linux with a Ryzen 9 3900X processor.

The AGESA 1.0.0.3 ABBA update has an improved boost clock frequency algorithm along with changes to the idle state handling. This AGESA update should better position AMD Ryzen 3000 processors with the boost clock behavior expected by users with better hitting the maximum boost frequency and doing so more aggressively.
