  • I’m not familiar with KDE’s new feature yet, but if it only supports sysfs LEDs then it won’t control 99% of keyboards. Few RGB keyboards have drivers that expose this interface. Most RGB keyboards are controlled from userspace on their official software on Windows, and that’s also what most Linux projects that control RGB devices including my OpenRGB project do. I wonder if it would be possible to write an OpenRGB plugin/script that exposes a virtual /sys/class/leds/openrgb device that KDE could talk to, then translate that into OpenRGB calls to set the color on all available devices. It doesn’t sound too difficult.














  • Any dating app where both people have to “like”/“swipe right” each other should allow either side to initiate tbh or at least opt out of the stupid matchmaking system and accept all incoming matches.

    I was on the dating apps last summer after having been out of the dating pool for 6 years and the current crop of apps are pretty awful for men (amd probably women as well, maybe for difderent reasons). When I used dating sites in the early/mid 2010s most sites let anyone initiate a conversation so you didn’t need to worry about the (usually paywalled) “like” system. These days literally everything is a Tinder clone and the only interaction you have with the app is like or dislike. I get why they did it because women receive so much bullshit from unsolicited messages, in my experience it devolved into just mashing the Like button over and over again blindly because it’s a shitty numbers game and the odds aren’t in your favor. There’s no sense reading through detailed profiles and making thoughtful decisions when it’s rare to get a match anyways. Easier to like every single profile and then be the one to filter out matches once they come in. If the harassment is going to primarily target women and women are the ones who need to be more selective in their matches, the dating apps should let women be the ones to pick matches, or better yet give each and every user a toggle that lets them accept matches from anyone, because that makes it easier to get over the hurdle of not receiving any matches at all.

    I eventually gave in and paid for the Tinder upgrade that lets you like an unlimited amount of times. I just mindlessly mashed the like button until the queue was empty every day. Before long, matches were actually happening. Two months into that nonsense I actually got a perfect match (she sent the first message) and we’ve been together for 6 months now. I absolutely love her and I’m glad it worked out, but damn was dating on Tinder, Bumble, OKCupid, and POF a horrible experience all around. All owned by the absolutely dreadful Match.com now of course. The prospect of your perfect match being hidden behind a stupid loot box RNG style gacha system is absolute insanity, because that’s what it is. You have a limited number of likes and the profiles you get to see are seemingly picked at random.




  • Squeekboard is where it’s at. By far my favorite onscreen keyboard for Linux and mainly because you can easily create your own layouts using .yaml files. I’m tired of virtual keyboards that omit keys needed for development and terminal use or shove them off to separate tabs. My custom Squeekboard layout fits my needs exactly and I’m pretty fast at typing on it (typing this on it now). I wish it were usable outside of Phosh, though tbf I haven’t tried. Between GNOME Mobile, KDE Plasma Mobile, and Phosh (Squeekboard), I choose Phosh primarily because of how much I like Squeekboard.


  • Except that in the case of VGA (and DVI, HDMI, and DisplayPort) the i2c interface is intended for use over the cable. All of those ports have a pair of i2c pins and corresponding wires in their cables. The i2c interface is used for DDC/EDID which is how the computer can identify the capabilities and specifications of the attached display. DDC even provides some rarely-used control functionality. Probably the most useful of which is being able to control the brightness of the display from software. I use the ddcci module on Linux and it lets me control my desktop monitor brightness the same way a laptop would, which is great. I have no idea why this isn’t widely used.

    Edit:

    This i2c interface is widely used to control the lighting on modern graphics cards that have RGB lighting. We’ve spent a lot of time reverse engineering these chips and their i2c protocols for OpenRGB. GPU chips usually have more i2c buses than the cards have display connectors, so the RGB chip is wired to one of the unused buses. I think AMD GPUs tend to have 8 separate i2c buses but most cards only use 4 or 5 of them for display connectors. There is also an i2c interface present on RAM slots normally used for reading the SPD chip that stores RAM module specifications, timings, etc. This interface is also used for RAM modules with controllable RGB lighting.


  • Yeah, the lack of proper discoverability on i2c truly sucks. You have to just poke random addresses and hope for the best to see if an i2c device exists on the bus. It’s a great standard but I wish it would get updated with some sort of plug and play autodetection feature. Standardized device PID/VID system like USB and PCI would be acceptable or a standardized register that returns a part string. Anything other than blindly poking registers and hoping you’re not accidentally overvolting the CPU or whatever because the register on your expected device overlaps with the overvolt the CPU register on the same address of a different device.
