  • Turing Pi: A Plug-and-Play Raspberry Pi Cluster - IoT Tech Trends

    The Raspberry Pi is a versatile and relatively inexpensive single-board computer that you can use in a range of projects. However, if you really want to take your Raspberry Pi projects to the next level, you may want to build a Raspberry Pi cluster. This is where the Turing Pi v1 can come in handy. It allows you to easily connect multiple Raspberry Pis together to form a cluster.

  • Lidl (Silvercrest and Livarno Lux) branded Zigbee products for Open Source users

    The LED strip worked immediately with my Domoticz setup using a Zigate stick and Raspberry Pi. Notice that the diagram is wrong, the arrow on the controller must align with the VCC label on the LED strip.

    I opened up one of the gateways to see what it is and whether it can be adapted to run free, open source software. Inside, it is the Tuyo TYGWZ-01 white label gateway. On the board, there is a Realtek RTL8196E router chip, radio module with label 330010257 and part no. 2.22.46.00001 and an EM6AA160TSE-5G DRAM chip.

Trisquel 9 Review: Freedom Vehicle

Here is my review of Trisquel 9.0 Etiona the newly released computer operating system. It is the successor of Flidas and now based on Ubuntu 18.04.

Postgresql service failed because the control process exited with an error code

PostgreSQL is a free and open-source, community-driven, standard-compliant, and most popular object-relational database management system. It is used by popular IT companies like Uber, Netflix, Instagram, Spotify, etc. Recently I installed PostgreSQL and getting an error while running daemon. This is mainly because PostgreSQL not getting sufficient permission to create the folder required to store database information. Read more

  • Bob’s 2021 Tech Predictions: What a Difference a Pandemic Makes

    I predicted that IBM would dump a big division and essentially remake itself as Red Hat, its Linux company. Well yes and no. IBM did announce a major restructuring, spinning-off Global Technology Services just as I predicted (score one for me) but it has all happened slowly because everything slows down during a pandemic. The resulting company won’t be called Red Hat (yet), but the rest of it was correct so I’m going to claim this one, not that anybody cares about IBM anymore.

  • openSUSE Smiles

    There is no end to my amazement of the openSUSE community. They do such a fantastic job of making a wonderful distribution with all the tools that keep me productive. I am very thankful for the reliability I enjoy using openSUSE. The community members also do a great job of helping me through a jam, should I drive myself into one.

  • Retroarch for Android – The Complete Guide - Make Tech Easier

    The first thing you need to do, of course, is install Retroarch from the Play Store. Once you’ve done that, open Retroarch, and you’ll be presented with the main menu, which may mean absolutely nothing to you if you’re unfamiliar with Retroarch.

  • Junichi Uekawa: Yesterday was our monthly Debian meeting.

    Yesterday was our monthly Debian meeting. We do one every month for Tokyo and Kansai combined, because it's online and no reason to split for now. I presented what I learnt about nodejs packaging in Debian. This time, I started using Emacs for presentation, presenting PDF file. This week I switched most of my login shells to emacsclient, and experimenting.

  • WordPress Post Vs. Page

    Welcome back to the WordPress 101 series. In this series, we are discussing the basics of WordPress for new WordPress users. In this article, you’ll learn the differences between WordPress post vs. page. Often new users get confused between WordPress posts and pages. I remember my cousin created more than 10 pages before he realized he should’ve created posts, not pages. For new users, it may be difficult to understand why WordPress has two separate options to publish content. For them, one can create 200 pages instead of 200 posts and that should make no difference in how search engines see that content.

  • GCC's Profile Guided Optimization Performance With The Ryzen 9 5950X - Phoronix

    Given the talk in prior days around patches for PGO'ing the Linux kernel and some readers not being familiar with Profile Guided Optimizations by code compilers, here are some fresh benchmarks on a Ryzen 9 5950X looking at the benefits of applying PGO optimizations to various benchmarks. We have benchmarked GCC and Clang PGO performance many times over the years with this just being some fresh data using a Ryzen 9 5950X and the latest software stack on Ubuntu 20.10. The testing was done by first running various open-source benchmarks without PGO, repeating the tests to generate profiles for the compiler to consume with PGO, and then benchmarking those PGO-enabled builds. These numbers are about best case scenarios given that with the testing for the PGO-enabled build, the benchmarks are repeated and thus matching well to the original profile. In more real-world, general purpose scenarios it can be more difficult generating an accurate profile for your actual workflow / software usage.

  • I told you so, 2021 edition

    You will recall that in 2004, which is now seventeen years ago, I wrote a document explaining why I made the design trade-offs that I did in XScreenSaver, and in that document I predicted this exact bug as my example of, "this is what will happen if you don't do it this way."

    And they went and made that happen.

    Repeatedly.
