  • Flask Delicious Tutorial : Building a Library Management System Part 3 - Routes

    I have configured what we need in this repo: DeliciousFlask-3.1. Download it, and run app.py (If you are new to python see Part2).

  • Talk Python to Me: #259 From Academia to Tech Industry and Python

    Did you come to Python from the academic side of the world? Maybe got into working with code for research or lab work and found you liked coding more than your first field of study. Whatever the reason, many people make the transition from the academic world over to tech and industry.

    On this episode, you'll meet three women who have made this transition, and you'll hear their stories. I'm excited to speak with Jennifer Stark, Kaylea Haynes, and Eslene Bikoumou about their journey to the tech field.

  • Test and Code: 108: PySpark - Jonathan Rioux

    Apache Spark is a unified analytics engine for large-scale data processing.
    PySpark blends the powerful Spark big data processing engine with the Python programming language to provide a data analysis platform that can scale up for nearly any task.

    Johnathan Rioux, author of "PySpark in Action", joins the show and gives us a great introduction of Spark and PySpark to help us decide how to get started and decide whether or not to decide if Spark and PySpark are right you.

  • Temporary Contact Number based Contact Tracing

    I have already talked here before about privacy preserving contact tracing to fight Covid-19 but I figured I give an update to this. I have spent the last week now investigating different approaches to this and my view has changed quite a bit.

    I strongly believe that contact tracing through phone apps is one of our best chances to return to normal and without losing our civil liberties. If you want to understand why, have a look at previous post about this topic.

    [...]

    If your local government is planning on implementing a covid tracing app it might be worth directing them towards Co-Epi. It already has an implementation of many of the same ideas in their GitHub repository. If they do want a centralized approach the Singaporean government Open Sourced their application under GPL3 under the name BlueTrace. It avoids largely unnecessary cloud infrastructure from what I can tell.

What Makes a System76 Computer?

In homage to the revolutionary age of 1776, System76 revolutionizes open source technology and declares independence from our proprietary rulers. But what are the key ingredients that go into making a computer so revolutionary? The following delicious details outline the qualities we value in all of our computers. Note: Licking your screen is not an effective way to taste the deliciousness of this blog post. System76 users depend on heavy computational power to get their work done, and in some cases require a literal heavy computer. Our hardware is designed to support top-line processors and graphics cards, allowing you to consistently plow through your workload. We’re not going to call on a sedan to do a bulldozer’s job.

ZFS focus on Ubuntu 20.04 LTS: ZSys general principle on state management

After our previous general presentation of ZSys, it’s “”“time”“” to deep dive to one of its main predominant feature: state management! A little technical detour first. as this question will necessarily arise, especially from those familiar with ZFS concepts. We have purposively chosen the “state” terminology to prevent system administrators and in general, all those familiar with ZFS to confuse if with snapshot datasets. Basically a state is a set of datasets, all frozen in time (apart from the current state), which regrouped together forms a system “state” that you can chose to reboot on. Those group of datasets can be either made of snapshot datasets (read only) (which is what most of advanced ZFS users will expect), but it can also be filesystem datasets (read write), made of filesystem datasets clone of the current state datasets. You can boot to any of those. Read more

Apache Subversion 1.14.0

KDE Applications, Wireshark, IceWM update in Tumbleweed

The last week has produced a total of three openSUSE Tumbleweed snapshots bringing the total amount of snapshots for the month to 18. All 18 snapshots have recorded a stable rating above 91, according to the Tumbleweed snapshot reviewer. With 14 of them, recording a rating of 99 and the last two snapshots trending at a 99 rating. The most recent 202000526 snapshot provided the 3.2.4 release of Wireshark. The new version fixed a Common Vulnerabilities and Exposures where it was possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. Linux Kernel 5.6.14 re-established support for RTL8401 chip version. DNS server and client utilities package bind 9.16.3 fixed to security problems and added engine support for OpenSSL Edwards-curve Digital Signature Algorithm implementation. Document viewer evince 3.36.1 updated translations, fixed an incorrect markup in the Czech User Interface and updated the French help image. SSL VPN client package openconnect 8.10 installed a bash completion script and fixed a potential buffer overflow with security communications library GnuTLS. GNOME’s 0.30.10 image organizer shotwell, which was the subject of a recently settled a patient lawsuit, modified web publishing authentication to comply with Google’s requirements. Read more
