I started Crowbits Master Kit review last month by checking out the content, user manual, and some of the possible projects for the ESP32 educational kit including a 2G phone and a portable game console. For the second part of the review, I’ll go through one of the lessons in detail, namely the intrusion scanner to show the whole process and how well (or not) it works. Let’s go to Lesson 5 directly, although I’d recommend going through the first lessons that provide details about the hardware and visual programming basics using Letscode program, which is basically a custom version of Scratch for Crowbits

It’s small base board for RP2040-PICO the $4 module with the Cortex-M0+ processor made by Raspberry Pi foundation.

We were ready with the prototype for a long time but the RP2040-PICO modules were tricky to source

Espressif Systems introduced their first RISC-V wireless SoC last year with ESP32-C3 single-core 32-bit RISC-V SoC offering both 2.4GHz WiFi 4 and Bluetooth 5.0 LE connectivity, and while the company sent some engineering samples of ESP32-C3 boards months ago, general availability of ESP32-C3-DevKitM-1 and modules is expected shortly. But the company did not stop here, and just announced their second RISC-V processor with ESP32-C6 single-core 32-bit RISC-V microcontroller clocked at up to 160 MHz with both 2.4 GHz WiFi 6 (802.11ax) and Bluetooth 5 LE connectivity.

While EXT4 supports both case-folding for optional case insensitive filenames and does support file-system encryption, at the moment those features are mutually exclusive. But it looks like the upcoming Linux 5.13 kernel will allow casefolding and encryption to be active at the same time. Queued this week into the EXT4 file-system's "dev" tree was ext4: handle casefolding with encryption.

Arguably the most interesting RISC-V board announced to date is SiFive's HiFive Unmatched with the FU740 RISC-V SoC that features four U74-MC cores and one S7 embedded core. The HiFive Unmatched also has 16GB of RAM, USB 3.2 Gen 1, one PCI Express x16 slot (operating at x8 speeds), an NVMe slot, and Gigabit Ethernet. The upstream kernel support for the HiFive Unmatched and the FU740 SoC continues. With the Linux 5.12 cycle there was the start of mainlining SiFive FU740 SoC support and that work is continuing for the upcoming Linux 5.13 cycle.

While FreeBSD and OpenBSD both switched to using LLVM/Clang as their base system compiler, NetBSD picked a different path and remained with GCC and binutils regardless of the license change to GPLv3. However, it doesn't mean that the NetBSD project endorses this license, and the NetBSD Foundation's has issued a statement about its position on the subject.

Realistically, NetBSD is more or less tied to GCC, as it supports more architectures than the other BSDs, some of which will likely never be supported in LLVM.

As of NetBSD 9.1, the latest released version, all supported platforms have recent versions of GCC (7.5.0) and binutils (2.31.1) in the base system. Newer (and older!) versions of GCC can be installed via Pkgsrc, and the following packages are available, going all the way back to GCC 3.3.6: [...]

10 days ago, I bought this X1 Carbon. I immediately installed OpenBSD on it. It took me a few days to settle in and make myself at home, but here are my impressions.

This was the smoothest experience I've had getting OpenBSD set up the way I like it. The Toshiba NB305 in 2011 was a close second, but the Acer I used between these two laptops required a lot more tweaking of both hardware and kernel to get it to feel like home.

People have been asking me to play MineTest for ages so I thought I should finally get around to it, if you've never heard of it MineTest is an open source Minecraft clone that surprisingly has a lot of community support

OpenTTD, the free and open-source software recreation of Transport Tycoon Deluxe, has been a popular game for a long time, but recently something unusual happened. The team behind the project decided to release the game on Steam (still free as always) and this has changed everything. Let me explain why this matters. If you have ever played OpenTTD on Linux, let me venture that you have probably relied on your distro’s package manager to keep your game up-to-date. In theory, this is the BEST way to keep your packages up to date. Rely on maintainers. In practice however, it’s far from being something you can rely on, beyond security updates. Debian stable tends to have really old packages, sometimes years behind their latest versions. So on Debian stable you end up with OpenTTD 1.08 as the most recent version. That’s what shipped in April 2018. Just about 3 years old.

Portal Stories: Mel, an extremely popular and highly rated mod for Portal 2 just had a new Beta pushed out which adds in Vulkan support for Linux. Much like the update for Portal 2 that recently added Vulkan support, it's using a special native build of DXVK, the Vulkan-based translation layer for Direct3D 9/10/11. Compared with the Portal 2 update, in some of my own testing today it seems that Portal Stories: Mel seems to benefit from the Vulkan upgrade quite a bit more in some places. At times giving a full 100FPS increase! So for those on weaker cards, this will probably be an ideal upgrade. Another game to test with Vulkan is always great too.

TeamSpeak is a free voice conferencing software available to install on Linux, Windows, macOS, FreeBSD, and Android. It is the pioneer in its areas of other platforms such as Discord.

The Linux kernel includes the Netfilter subsystem, which is used to manipulate or decide the fate of network traffic headed into or through your server. All modern Linux firewall solutions use this system for packet filtering. [...] The default behavior of the UFW Firewall is to block all incoming and forwarding traffic and allow all outbound traffic. This means that anyone trying to access your server will not be able to connect unless you specifically open the port. Applications and services running on your server will be able to access the outside world.
