Ubuntu 20.04 LTS Is Now Powered by Linux Kernel 5.15 LTS from Ubuntu 22.04 LTS On August 2nd, 2022, Canonical published a new Ubuntu kernel security updates for Ubuntu 22.04 LTS and Ubuntu 20.04 LTS systems that address four security vulnerabilities, including a remote code execution. The interesting part is that Canonical lists only Linux 5.15 kernels for both Ubuntu 22.04 LTS and Ubuntu 20.04 LTS as being patched, despite the fact that Ubuntu 20.04 LTS runs Linux kernel 5.13 since the release of the Ubuntu 20.04.4 LTS point release back in February 2022. Games: Steam Deck, Nintendo Online, and More Steam Deck Beta update brings bug fixes, external display improvement Valve has released a small update to the Steam Deck Beta branch, mostly bug fixes but also an improvement for handling external displays. Here's what's new. Stealth-action game Republique is now FREE and Steam Deck Verified Consider this your quick tip of the week, as Republique from developer Camouflaj is now free to keep on Steam and it's also Steam Deck Verified! The developer has reached their 10 year anniversary as a studio, so they've put Republique free as it was their first game. A nice little gesture. No need to wait on Valve, the Steam Deck Docking Station from JSAUX is great While many will no doubt wait on Valve for the official Steam Deck Dock, a lot of hardware vendors are coming out with their own versions. JSAUX are one of them and they sent over their Docking Station for Steam Deck for me to take a look at. Steam gets support for Nintendo Online classic controllers Valve recently released an update for the main Steam client, which amongst other things brings support in Steam Input for the Nintendo Online classic controllers. These are the special controllers Nintendo offers for playing their classics on Nintendo Switch, although Steam having support for them makes sure they have a whole lot more life. The GNU C Library version 2.36 is now availableThe GNU C Library ================= The GNU C Library version 2.36 is now available. The GNU C Library is used as the C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the kernel. The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C11 and POSIX.1-2017. It is also internationalized and has one of the most complete internationalization interfaces known. The GNU C Library webpage is at http://www.gnu.org/software/libc/ Packages for the 2.36 release may be downloaded from: http://ftpmirror.gnu.org/libc/http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html NEWS for version 2.36 ===================== Major new features: Support for DT_RELR relative relocation format has been added to glibc. This is a new ELF dynamic tag that improves the size of relative relocations in shared object files and position independent executables (PIE). DT_RELR generation requires linker support for -z pack-relative-relocs option, which is supported for some targets in recent binutils versions. Lazy binding doesn't apply to DT_RELR. On Linux, the pidfd_open, pidfd_getfd, and pidfd_send_signal functions have been added. The pidfd functionality provides access to a process while avoiding the issue of PID reuse on tranditional Unix systems. On Linux, the process_madvise function has been added. It has the same functionality as madvise but alters the target process identified by the pidfd. On Linux, the process_mrelease function has been added. It allows a caller to release the memory of a dying process. The release of the memory is carried out in the context of the caller, using the caller's CPU affinity, and priority with CPU usage accounted to the caller. The “no-aaaa” DNS stub resolver option has been added. System administrators can use it to suppress AAAA queries made by the stub resolver, including AAAA lookups triggered by NSS-based interfaces such as getaddrinfo. Only DNS lookups are affected: IPv6 data in /etc/hosts is still used, getaddrinfo with AI_PASSIVE will still produce IPv6 addresses, and configured IPv6 name servers are still used. To produce correct Name Error (NXDOMAIN) results, AAAA queries are translated to A queries. The new resolver option is intended primarily for diagnostic purposes, to rule out that AAAA DNS queries have adverse impact. It is incompatible with EDNS0 usage and DNSSEC validation by applications. On Linux, the fsopen, fsmount, move_mount, fsconfig, fspick, open_tree, and mount_setattr have been added. They are part of the new Linux kernel mount APIs that allow applications to more flexibly configure and operate on filesystem mounts. The new mount APIs are specifically designed to work with namespaces. localedef now accepts locale definition files encoded in UTF-8. Previously, input bytes not within the ASCII range resulted in unpredictable output. Support for the mbrtoc8 and c8rtomb multibyte/UTF-8 character conversion functions has been added per the ISO C2X N2653 and C++20 P0482R6 proposals. Support for the char8_t typedef has been added per the ISO C2X N2653 proposal. The functions are declared in uchar.h in C2X mode or when the _GNU_SOURCE macro or C++20 __cpp_char8_t feature test macro is defined. The char8_t typedef is declared in uchar.h in C2X mode or when the _GNU_SOURCE macro is defined and the C++20 __cpp_char8_t feature test macro is not defined (if __cpp_char8_t is defined, then char8_t is a builtin type). The functions arc4random, arc4random_buf, and arc4random_uniform have been added. The functions wrap getrandom and/or /dev/urandom to return high- quality randomness from the kernel. Support for LoongArch running on Linux has been added. This port requires as least binutils 2.38, GCC 12, and Linux 5.19. Currently only hard-float ABI is supported: - loongarch64-linux-gnu The LoongArch ABI is 64-bit little-endian. Deprecated and removed features, and other changes affecting compatibility: Support for prelink will be removed in the next release; this includes removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment variables and their functionality in the dynamic loader. The Linux kernel version check has been removed along with the LD_ASSUME_KERNEL environment variable. The minimum kernel used to built glibc is still provided through NT_GNU_ABI_TAG ELF note and also printed when libc.so is issued directly. On Linux, The LD_LIBRARY_VERSION environment variable has been removed.

In this project, I built a gesture-controlled robot using ESP32 communication and the MPU6050 accelerometer & gyroscope sensor. The transmitter ESP32 reads hand movements from the MPU6050 and sends motion data wirelessly to the receiver ESP32, which controls the robot’s direction (forward, backward, left, right, and stop).

This video is a full walkthrough of my Solar Kiln + OTGRND RMS (Remote Monitoring System) build — even though I didn’t capture a ton of the early construction on camera. I used SketchUp screen recordings and other data I have gathered to show the kiln layout and sensor placement, plus some of the data we are getting in.
Most importantly: I now have about a week of real kiln data to review. The environment readings are looking good, but the moisture content (MC) channels got noticeably noisier once the probes moved from my office test setup out to the kiln with longer cable runs. In this video I touch on that, and what we’re going to test next.
A big part of this project has been working with my AI engineering buddy; It has named itself "Sage"… weird huh?? (AKA ChatGPT) to iterate quickly on firmware, payloads, troubleshooting ideas, and test plans — and you’ll see how that helped keep momentum.
Next improvements we’re working on • New firmware that exposes MC sensor parameters (settle time / sampling / etc.) so I can tune it without constant rebuilds • Kiln airflow baffling: using barriers to force air through the stack instead of short-circuiting • User ideas: List them in the comments, I’d love to try some of your ideas to see if we can get this solar Kiln working in the best possible way. What is cool is we can see the changes in the data and see if things really helped or not
I’d love your help (seriously) If you’ve built a solar kiln or you’ve dealt with long-run analog sensor noise: • Best practices for air baffling and intake/exhaust placement? • Any other idea??? Drop ideas in the comments — I’ll incorporate the best ones in the next iteration. ________________________________________ Hardware / Stack • Heltec ESP32-S3 LoRa nodes (kiln node + base receiver) • LoRa link to base station • Raspberry Pi running Mosquitto MQTT + bridge service • Key=value payload schema (simple, debuggable) SCHEMA • Serial → MQTT bridge that routes events/telemetry
