@ocornut EU cookie law is not the problem. You don't need to ask for consent for essential cookies, like the ones that store your login session ID or the shopping cart in a web store.

Every time you see the cookie popup, it's about selling your browsing data to third parties.

We see these popups everywhere and the reasoning is "the EU did something stupid", but it's the opposite. They caught the thieves red-handed.

"We value your privacy." Yeah, no shit. By putting a monetary value on it.

It's hard to remember how much screen space was taken up by useless stuff in early browsers.

The screenshot is more or less 640x480, which by 2000 was obsoleted by the ginormous 800x600 screen resolution.

So, uh...

VkSurfaceCapabilitiesKHR's minImageCount is always 2 on Nvidia GPUs.

On Intel/AMD/llvmpipe, minImageCount is 3 for VK_KHR_xcb_surface and VK_KHR_xlib_surface.

For VK_KHR_wayland_surface the minImageCount value is 4.

An interesting topic came up in the PRs, related to the recent blog posts by @forrestthewoods.

Should it be acceptable for a C++ build process to require network availability to succeed?

To put it in context, the network would be used to download the source code of some of the libraries that need to be compiled and linked into your program.

My stance is that builds should be local only, but maybe I'm just an old man who hasn't noticed that modems are long gone by now?

What are your opinions?

For some time now I've been working on BC7 support in etcpak.

The codec I used as a base is Rich Geldreich's bc7enc, the 4-mode fast one. The results are bit-exact, so don't bother with checking the metrics.

(I find it hard to understand why you would want to go with a full-featured and slow codec (such as bc7e.ispc) and then put RDO on top, which degrades the quality way below what the fast codec can achieve.)

Ugh, groff 1.23 removes color from man pages. Using bold and underline text attributes makes more sense in theory, but the monochrome text is much harder for me to read.

Top: new, bottom: old.

There's something very wrong with the way mouse cursors are handled on Linux. If you have a low DPI display, the Adwaita cursor is ugly and pixelated. The same cursor image in the KDE theme preview is smooth and nice.

This is a common problem in GNOME, KDE, and wlroots. Probably because they all use the same library to load the cursor and... nobody noticed?

Oh, and of course I have to take photos of the screen, because screenshots do not include the actual cursor image that is displayed.

Why is clang taking 5 minutes to compile a relatively small C++ (168 KB) source file? Let's see...

https://github.com/ggerganov/llama.cpp/blob/917dc8cfa67a72fb7c8bf7392270da3bf4833af4/unicode-data.cpp

Ah, oh, um... That's not how you do it.

Here's 10 MB of data as source code that compiles in about 8 seconds:

How common are forced separate gfx and present queues in Vulkan? Does this separation exist on real hardware, or is it just a theoretical possibility?

To see if present is supported on a queue, you need to pass a surface to draw on to vkGetPhysicalDeviceSurfaceSupportKHR. This allows you to select the queue setup that will work.

But what if you don't have a surface to render to yet, but want to create a VkDevice that will be able to present?

I'm looking for solutions to problems with Meson, and fuck, this is so miserable and soul draining.

Let's say you have Android NDK or vcpkg or whatever installed somewhere on the system. One user will have it in C:, another in Z:\dev, and someone else in /home/user/sdks/, or I don't know, /opt/ or /usr/local/. It doesn't matter.

What everyone does is set up an env variable pointing to the SDK dir that can be picked up by the build system, and everything works no matter what setup you prefer.

Remember that you can convert your JPEG files to JPEG XL with no loss of quality and you will save a lot of space. In theory, it should be possible to revert back to JPEG and have the same file, bit for bit, should you have the need.

A sample set of 203 photos from 2007:

JPEG: 654 MB
JPEG XL: 532 MB

JPEG dates back to 1992 and was the hot new thing on your Amiga. Why do you still use it?

Me, yesterday, at a day job meeting: "The "big" Visual Studio is a dying product."

Microsoft, today: https://devblogs.microsoft.com/visualstudio/visual-studio-ui-refresh/

Yes, this is exactly what we all wanted: more spacing between everything so that less is visible on the screen! I can't wait to see the "improved" reliability and robustness that comes with this new UI framework. One that we're already seeing in the Windows 11 shell and explorer! It's going to be great!

OMG, Path of Exile achievements only sync with Steam when you play with mouse and keyboard. Achievements will not sync when playing with a gamepad.

Wayland is a gift that keeps on giving.

When you create a wl_surface, it won't be active or visible until you attach a wl_buffer to it. And when you want to hide the window, sorry, the surface, you just attach a null buffer to it and it's gone.

If you are rendering with Vulkan, you call vkCreateWaylandSurfaceKHR() and tell it which surface you want to draw on. It will automatically attach a buffer to the surface when you make the present call.

Pretty simple, right?

Image viewers on Linux are in such a strange place. 30+ year old formats? Sure. Anything more modern? Roll the dice. Compressed textures? Lol!

There's this text-based viewer I like that outputs sixel data to the terminal. I wanted to see how I could extend it to support more formats. Turns out it's just an argv parsing shim over some Rust libraries.

Some graphical viewer? Qt was built wrong, so no JXL support. And it's 5 FPS when you pan an image, because everything is software rendered.

About a decade ago, I was looking for some kind of CI solution that I could run on the ARM devboard I had running as a server at home.

Jenkins and TeamCity were out of the question due to the amount of resources they required to even get started. I tried, but after an hour of constant swapping and not even seeing a splash screen, I got bored.

It felt completely absurd to me, as the CI system I needed was supposed to just monitor the git repo and run a shell script to do the build.

Nvidia driver with external sync is in beta.

Seems to work as expected. No more black flicker in Resolve, Noita, or Stardew Valley. No previous frames during hitches in Star Citizen.

"should not be possible"

Hahaha, and on Wayland it is not possible, because clients must not have knowledge of where their windows are on the screen.

Sigh.

PNG load times in etcpak, using different variants of zlib.

In 1.2.11, I had the CRC calculation patched out and used the manual assembly files that you had to somehow include in the build process.

In 1.3.1, support for assembler code was removed because "there is not sufficient gain from the inflate assembler code to warrant its inclusion." (https://github.com/madler/zlib/commit/288f1080317b954b6bdca33708631c011549c008)

Finally, I use zlib-ng as a drop-in replacement for zlib. I just need to compile it with the ZLIB_COMPAT CMake option enabled.

I spent much of yesterday evening chasing a crash in the Intel driver and/or validation layers. Finally it turned out that it was fixed in the validation layers back on January 18th.

But the latest release on GitHub is 1.3.275, made on January 10th. And it's actually something Android related instead of a proper release?

Looking at the git tags, there have been 4 "non-releases" and we're now on v1.3.279.

Is there any kind of process to this at all?

A propos Firefox vs. Chrome. Some time ago, I largely stopped trying to open any web pages on my phone because the Chrome experience of unfiltered web was intolerably painful. Then I installed Firefox with uBlock and things became manageable.
