Linux 6.18 LTS release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.18

Linus Torvalds has just announced the release of Linux 6.18 on the Linux Kernel Mailing List (LKML), which will likely become the next LTS kernel [update: it’s now official]: So I’ll have to admit that I’d have been happier with slightly less bugfixing noise in this last week of the release, but while there’s a few more fixes than I would hope for, there was nothing that made me feel like this needs more time to cook. So 6.18 is tagged and pushed out. Most of the last-minute fixes are minor fixes to drivers, with some random noise elsewhere (bluetooth, ceph, afs..). Nothing strikes me as standing out, but hey, there’s a shortlog appended if you want to see the details. And this obviously means that the merge window will open tomorrow, and I already have three dozen pull requests pending. Thanks. And as I already mentioned a couple of […]

Taradov’s open-source hardware pocket USB sniffer works with Wireshark

Taradov USB Sniffer v6

Alex Taradov has designed a low-cost, open-source hardware USB sniffer compatible with the popular Wireshark packet capture utility, and also controllable from the command line, capturing data in the standard PcapNG format in either case. Wireshark has had built-in USB capture capability for many years, and I used it myself to reverse-engineer the software for a USB video capture card around 2007, but it’s not perfect since it does not capture low-level packets. For that, you need extra hardware, and last year we covered the tinysniffer USB sniffer based on a WiFi-connected Linux SBC. It does the job, but it’s sold for $199, and you don’t need an application processor to handle USB 2.0 speeds. Alex’s design is optimized for cost and built around three main components: Cypress CY7C68013A 8051 MCU, Lattice MachXO2 LCMXO2 FPGA, and Microchip USB3343 USB PHY. Taradov’s USB sniffer specifications: Microcontroller – Cypress CY7C68013A enhanced 8051 […]

Black Friday and Cyber Monday 2025 – International deals, coupons, and events

AliExpress Black Friday 2025

Like every year since 2014, I’ll list a few international deals for Black Friday and Cyber Monday 2025, as many CNX Software readers cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events, which will take place from November 20 to December 1. I’ve gathered various deals, discount coupon codes, and events from relevant manufacturers of single board computers, MCU development boards, mini PCs, Smart Home devices, and DIY products, as well as popular online stores, including AliExpress, Banggood, and others. AliExpress Black Friday and Cyber Monday 2025 event AliExpress sales event for Black Friday and Cyber Monday 2025 has just started and will last until December 3, 2025 (although I can see until November 29 and December 4 in some places). You can use some of the coupons on the screenshot above, or some alternative coupon codes for the US and some other countries (excluding DE, RU, […]
