Using plain gzip -9 on the 12MB uncompressed image, i get 6953 KiB, smaller than your PNG. Using a stronger gzip compressor (zopfli) i get as little as 6294 KiB.

The PNG file format is essentially ZIP(BMP), trying to compress the raw pixels in a pretty naive way. It works extremely well for diagrams and large blocks of identical colours. But for real-world photos, AAA game screenshots, or even just

Telegram has 800 million monthly active users (10% of the whole earth population), it's definitely more than only war news.

Thanks for the update - IMO the debacle ranges over the last 4 years or so, where GCC refused to upstream support for RVV 0.7 until now (14.1) and that only living in out-of-tree vendor toolchains, and so all the most popular boards (all wi

> Soon we’ll see many new 64-bit RISC-V SBCs based on the Sophgo SG2000 RISC-V SoC. This is an extremely unusual SoC with three main CPU cores with heterogenous ISA; 1 GHz C906 RISC-V, 1 GHz ARM Cortex-A53, and an extra 700 MHz C906 RISC

Here's some pseudocode for argument's sake: http://paste.debian.net/1317369 I don't think the immediate-mode code is really more straightforward. Retained mode looks just as simple and only has that one same

They both owner-draw every widget themselves (not using platform native widgets). Gio is pure Go, Fyne is cgo. Gio is immediate-mode, Fyne is retained-mode. Flamewar starts here: I don't know why anyone would seriously choose an immedi

They're precompiled for the console GPU architecture, not the PC architecture, so they can't be used directly and still need to be emulated - I think those precompiled shaders are the input to the ubershader.

It's already fixed - https://github.com/iv-org/invidious/pull/4552

That's quite funny - yes, not only is this a horrible wilful backdoor, it is also a GPL violation since the backdoor is a derived work without included source / distributed not in "the preferred form for modification".

NT 4 and Windows 2000 source code were leaked on Feb 12 2004. The second google result is a copy that Microsoft are hosting on their own website: https://github.com/lianthony/NT4.0

Use precomp or antiz to losslessly pre-transform the zip, and then use solid compression (e.g. tar.xz or zpaq).

It's easy to forget about supporting EAs on Windows - they are extremely uncommon because you practically need to be in kernelspace to write them. Ntoskrnl.exe has one or two EAs, almost nothing else does. (ADS are super commonplace an

You could do block device snapshotting today if you build your block devices on top of LVM. You can also somewhat do it with fsfreeze and remounting your mount point on top of a dm-snapshot target. Blksnap is better because it does not requ

Hope that https://github.com/veeam/blksnap/issues/2 becomes available soon. It's on v7 of posting to linux-block and will make snapshotting available for all block devices.

The source is pretty straightforward - it's calling `scrot -s -o` to a temp file, and then `tessaract` with no further preprocessing. https://github.com/RajSolai/TextSnatcher/blob/master/src/ser

Is this something like what Qt `QScrollerProperties::MaximumClickThroughVelocity` controls? It's not exactly an event, but a click-through would stop the scroll immediately.

1nm is the real physical size of a transistor that you would need, to get equivalent performance characteristics, if the transistor's other layout characteristics were fixed in 1997. The divergence is because when FinFET layout was int

I think this is a bit misleading. Prior to this, trademarks and domains were held by some of the lead developers. After this, it's the same people. It's not worse.

There must be more categories than this because Qt 5 on Wayland can do fractional scaling since some years, you may need to set QT_SCALE_FACTOR_ROUNDING_POLICY=PassThrough.

My understanding of the frustration is Codeberg had over-invested in Woodpecker CI and so were blindsided by the appearance of Gitea Actions runner, that was developed by a core contributor, funded by an external party. In my mind, Forgejo&

Does the UAC prompt always say "Verified publisher: Microsoft"? Even without controlling stdin, malware at medium integrity could prompt to run a malicious command, and users will only see Microsoft's good name in the popup.
