M-VAVE SMK-37 PRO

https://www.m-vave.com/productinfo/1431195.html

The M-VAVE SMK-37 PRO is a MIDI keyboard (controller) with a built-in DX7 compatible FM tone generator.

It would be so much more valuable if the firmware would be open source for the community to modify and improve.

Think twice about Wayland. It breaks everything!

Think twice before abandoning X11. Wayland breaks everything!

tl;dr: Wayland is not "the future", it is merely an incompatible alternative to the established standard with a different set of priorities and goals.

Wayland breaks everything! It is binary incompatible, provides no clear transition path with 1:1 replacements for everything in X11, and is even philosophically incompatible with X11. Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating e

Hacking HY300 Pro+ Projector (720p)

Hello manufacturer. Good device. But software we want to customize. If you allow, we will buy more.

Despite being advertised as "4K 1080P", it really downscales those to 720P.

But for 28.50 EUR from Amazon Warehuose Germany in 2025, one can't exactly complain. https://www.amazon.de/dp/B0DSP74YQW

Chengdu Hotack Technology Co., Ltd. is the OEM?

Are we XLibre yet?

X11 has been, and still is, a vital piece of technology at the core of professional Unix-like workstations since decades. It has a proven track record of supporting enterprise-grade applications with long-term protocol stability and platform compatibility. It has matured over decades. XLibre is an actively developed fork of the X.Org X11 server, initiated by the most active X.Org developer and supported by the open source community.

An incompatible alternative, Wayland, is being aggressively pushed by IBM = Red Hat = Gnome = Fedora = freedesktop.org. However, it is not ready to succeed X11 as it its governance model leads to never-ending discussions and prevents even the most essential functionality from existing. Think twice before abandoning Xorg. Wayland breaks everything!

It is time that the open source community reclaims what was ours to begin with. This page lists distrib

Liberate desktops from ugly fonts

Blocking unwanted fonts

Certain surrogate fonts have plagued open source desktops for way too long, making them all look ugly. Trying to uninstall them will lead to the package manager uninstalling other vital packages, and just deleting them will reinstate them on package updates. The clean solution is to block them in fontconfig.

On FreeBSD (Linux is similar, but without the "local" part):

Unlogischheiten

Vielleicht entsteht hieraus einmal ein Blog. Oder ein Buch. Gern kommentieren!

  1. Warum gibt es in der deuschen Spache kein Wort für unlogische Dinge? - Na gut, erfinden wir eben "Unlogischheiten"
  2. Warum ist vor der Kasse ein viel zu langes Warentransportband, aber nach der Kasse (wo der Kunde die Sachen einpacken muss) ist kein Warentransportband? - Wenn nach der Kasse ein Warentransportband in der gleichen Länge wie vor der Kasse wäre, würde das Einpacken und somit das Kassieren doch wesentlich beschleunigt
  3. Warum öffnen Läden dann, wenn die arbeitende (und somit Geld verdienende) Bevölkerung arbeitet? - Zumindest zwischen 9 und 17 Uhr könnten Retailer eigentlich schließen, weil Leute die Geld verdienen dann keine Zeit haben einzukaufen. Es wäre doch viel logischer, Läden erst um 17 Uhr zu öffnen und dann bis 2 Uhr offen zu lassen
  4. Warum reduzieren Läden "wegen Corona" ihre Öffnungszeiten? - Logisch wäre, die Öffnungszeiten zu verlängern, damit sich die gleiche Men

Polycom CX300 Linux HID

Polycom CX300 under Linux

The Polycom CX300 and similar Plantronics Calisto 540 (P540-M), snom UC600 are originally optimized for Microsoft Lync (Skype for Business) for Windows and Mac but can also be used with Linux. It shows up as a USB audio playback and recording device (this part works immediately out of the box) plus some USB HID (this needs to be made work; see below).

A honest Xiaomi Redmi 10C review focusing on what matters

A honest review focusing on what really matters in smartphones: Affordable price, reasonable performance and battery life, good software, no bloatware, ease of unlocking the bootloader, data protection and privacy. Most reviews on the net focus on superficial, unimportant stuff like an extra megapixel here or the form of the display notch there.

tl;dr: It is like Xiaomi is making it intentionally hard to get rid of their spyware-ridden, bloated firmware (requiring a SIM card, Mi account, Windows software, and a full week of waiting time). DO NOT BUY XIAOMI PHONES!

Looking at the sub-150 EUR mid range category, comparing with the Moto G31 and G22. The Xiaomi Redmi 10C has been for sale at ALDI in Germany for 139 EUR as of August 2022. (Actually, the Lenovo-owned company MEDION is distributing this phone to ALDI, what an irony that the
