Linux, Python, Security, and Open Source Software TIPS

💡 On a typical Linux system, you can find bluetooth devices that are paired, connected, and trusted using the following command line:bluetoothctl devices [ Paired | Connected | Trusted ] For example: List currently paired bluetooth devices:$ bluetoothctl devices PairedDevice 00:42:XX:YY:ZZ:YY XXBK85Device 00:FD:AA:XX:YY:X8 D-26@opensuse @fedora @debian #ZikTIPS #TechTips #SysAdmin #LinuxTips #CLI #OpenSUSE #Fedora #Debian #Linux #opensource

If you care about diversity in open source especially from marginalized communities like those across Africa – check out this talk I gave at the recent @opensuse Conference in Germany. I argue that the open source community can no longer afford to overlook developers in these regions. Their talent, perspectives and potential are vital to the future of open source everywhere.https://www.youtube.com/watch?v=olMcEiI8EVw#osC25 #Diversity #FOSS #Africa #OpenSource

Just finished watching an excellent presentation by Dorinda Bassey on "Modernizing Virtio GPU: A Rust-Powered Approach with vhost-device-gpu" at @KernelRecipes @redhat #kr2025 #KernelRecipes #Linux #Kernel #Embedded #OpenSource

I am really enjoying the talks coming out of the @KernelRecipes conference, running now through September 24. Especially looking forward to @gregkh 's session Today on "The CRA and What It Means for Us" Check out live stream at: https://www.youtube.com/watch?v=U7pZbCnJxEw#CRA #kr2025 #kernel #Embedded #Linux #OpenSource

RE: https://mastodon.social/@jzik/115225291806144141Thanks to everyone who replied, shared, or boosted my previous post about teaching Linux remotely.I've decided to offer my own 4-person class starting October 8th! It will be remote, & offered at a small cost. The schedule is flexible & course materials will be shared shortly.If you'd like to join or learn more, check the details here:https://joseph.zikusooka.com/?page_id=2807Boosts appreciated again!#Linux #Training #FediHire #FediHired #GetFediHired #FediJobs #jobs #RemoteWork #TechEducation #OpenSource

Wishing everyone attending DevConf.US a fantastic conference this weekend! Unfortunately, I won't be able to join you or give my previously scheduled talk, but I hope you all have a great time!#DevConfUS #DevConf_US #devconfus2025 #FOSS #OpenSource

Would anyone know which organizations offer opportunities for teaching Linux classes online & remotely? I am interested in sharing my expertise. I currently live in the GMT+3 time zone but am flexible.I have experience teaching Intro to Linux Systems Admin & Server management. I’ve successfully trained multi-day/person classes using BBB, Jitsi & Zoom.If you know of any or need training, pls let me know.Boosts appreciated!#FediHire #FediJobs #GetFediHired #jobs #FediHired #Linux #Training

I've uploaded the latest 𝐉𝐚𝐦𝐛𝐮𝐥𝐚 𝐎𝐒 image – version 𝟐𝟎𝟐𝟓.𝟗.𝟎. This release continues the work I've been doing to make Jambula OS, a reliable, lightweight Linux platform for SoC devices like the Raspberry Pi 5. If you're building smart automation solutions on embedded platforms, this update is definitely worth checking out.Highlights in this update: Bluetooth speaker support, Kea DHCP, and much more!https://code.jambula.net/zikusooka/Jambula-OS #JambulaOS #raspberrpi #Linux #smarthome #homeassistant #Opensource

The talks from this year's Open Source Summit Europe are now available @linuxfoundationCheck out the full playlist at:https://youtube.com/playlist?list=PLbzoR-pLrL6qKwLt8A787ggMLHNivOHve#OSSummit #OSSEU #linux #opensource

Hass Core Installer 2025.9.0 released! No major changes – I just updated to the latest Home Assistant release.This free and open source tool helps you install/upgrade Home Assistant via the (now deprecated) core method for those who prefer its flexibility. https://github.com/zikusooka/hass-core-installer#HomeAssistant #smarthome #FOSS #Linux #opensource

For anyone interested in using Kea DHCP server on buildroot, I have submitted a new package patch that is currently awaiting upstream review. You can check it out here: https://patchwork.ozlabs.org/project/buildroot/patch/20250903113307.100754-1-zik@jambula.net/@iscdotorg #ZikTIPS #buildroot #dhcp #networking #linux #opensource

💡 Calculate the number of days since a given date (e.g. 30 June 2025) on a Linux system:echo $(( ( $(date +%s) – $(date -d "2025-06-30" +%s) ) / 86400 ))@opensuse @fedora @debian #ZikTIPs #Linuxtips #LinuxTechTips #Linux #FOSS #Opensource

💡Did you know you can just run the mount command with -m flag to create a non-existent mount point instead of first creating it.e.g. mount -m /dev/sdc1 /myflash#ZikTIPs #linuxtips #techti #Linux #OpenSource

So I won't be able to attend or present my previously scheduled talk at #FOSSY2025 in Portland, OR. Disappointed to miss this amazing event and the vibrant #FOSS community. Nevertheless, I wish everyone attending a fantastic conference filled with inspiring talks and great connections. Hope to join you all in person at #FOSSY25 #FOSSY2026! @conservancy #OpenSource

In FOSS circles, we often speak of representation, equity and community – but are we truly reaching those most affected by the digital divide?2 weeks ago at the #opensuse conference in Nuremberg, I spoke about this & how it continues to shape access, opportunity & equity especially in rural regions of Africa. I explored how FOSS can be a tool for empowerment, resilience & impact @opensuseVideo: https://youtu.be/olMcEiI8EVw#FOSS #OpenSource #DigitalDivide #GlobalImpact #TechForGood #openSUSE

Had a great time at @opensuse Conference 2025 in Nuremberg! A highlight was the hands-on workshop by @tropicsquar, showcasing #TROPIC01 — the first open and auditable secure element. A big step for verifiable hardware #security in #Linux systems, edge devices & secure infrastructure.Thanks to the Tropic Square team for the great session and the devkit#HardwareSecurity #OpenSource #EdgeComputing #TROPIC01 #TrustedHardware #SecureChips#IoTSecurity #NoObscurity #OpenHardware #linux #opensource
