16 of the world's biggest blockchains can freeze user funds.
Core #XCB can't - by design.
Decentralization matters.

Critical communication infrastructure matters more than ever. Core is a pioneer in Central Europe, securing the last-resort comms layer. Issues in Spain & Portugal prove the need. Our command unit connects to a drone, flies w/o radiofrequencies, and carries Blockchain data. #XCB

I was using #XCB, I tried raw stuff to the #framebuffer and OMG 1000x faster! AND I can rip shttons of useless code out of my cloud client thin antibrowsers! #OldGuyCoding #Programming For the record, years ago I wrote a raw gui device driver for gui, it took me a few days, SDL took me MONTHS GET OFFA MY LAWN!

Deep down the #X11 (#xcb) rabbit hole now.
I decided to add a tray icon. I want it optional, with configurable behavior (minimize-to-tray, close-to-tray, no-tray).
Adding this thing was super simple with Qt. Getting anything other than the default behavior ... not so much. Doing lots of things with plain #xcb now.
I'm stuck at hiding the tool from a taskbar. #EWMH has _NET_WM_STATE_SKIP_TASKBAR. In #fvwm (#fvwm3), this works when setting it before the window gets mapped. Sending it as a "client message" when the window is already mapped seems to be just ignored 😠
I then tried #KDE (#kwin). Hm well, doesn't even honor the _NET_WM_STATE property set on the window before mapping it, IOW, it's *always* shown in the taskbar.
WTF? 😖❓

Found a small bug, #xcb requests were synchronously checked, but this only works when calling the _checked() flavor of them ... 🙈
Fixed in #qXmoji v0.4
Also added a clear button to the search field, this seems somewhat useful 😉

@bunnyhero I have a question, (you or anyone really) My thin client antibrowser for cloud apps used to be 252k and I've reduced it to 160k but as soon as I have to allocate an #xcb shared buffer it bloats to 8M (I need to do this to get from 2 frames a second to reasonable frames/sec) I REALLY REALLY miss scribbling into the frame buffer directly and not dealing with copycopycopy shtforbrains software #GetOffaMyLawn 🙂 (Still better than 300M chrome, but...)
-
Asking another way. #xcb 20 frames a second, no need for an 8meg local buffer, go! Be aware this would drop my thin client #antibrowser from 8.2Mbytes to 200Kbytes. Ideally I'd like a /dev/fb without sht on top like we had in late 90s, but I know that won't happen again
-
By using #xcb to get rid of fonts and then having to allocate memory for the screen buffer (WTF I can't use some memory I can guarantee is *somewhere* but not mine?!) my footprint for my #antibrowser thin client goes from a start of 160kbytes to 8Mbytes, this is not good, it is still less than bloated Chrome's 300Mbytes. Before, I scribbled at 1 or 2 frames a second, but couldn't do better. I need that 3rd option! decent frame rate and direct-er screen buffer access
