@pervognsen @rovarma @molecularmusing Can you elaborate on that last sentence? The assumption seems a bit far-fetched to me.

wolfpld, 5 days ago

@pervognsen @rovarma @molecularmusing Yeah, but it just reduces to: it's a library always available to be installed.

When I was using Gnome some time ago (when xwayland had broken DPI scaling on KDE), I avoided KDE applications, because there was always something wrong with them visually.

(Recently it turned out it might be https://gitlab.gnome.org/GNOME/adwaita-icon-theme/-/issues/288)

Some people may want to have a consistent look of their desktop UI. There are reasons why eg. Qt may not be installed on a system.

@pervognsen @rovarma @dotstdy @molecularmusing It amuses me to read about zsh being "new" or "modern". I have a screenshot (actual screenshot of a CRT, taken with a camera) of a kernel panic from 20 years ago, and it has the exact zsh prompt I still use today. Makes you think about how little innovation there is in unix shells.

@pervognsen @dotstdy Why weird? You can have two broken cores in a chiplet due to random silicon defects and still be able to sell it if you only enable 6 cores. Getting a fully functional chiplet is presumably rare, so the price is higher.

@pervognsen @theWarhelm @forrestthewoods All Tracy does is checking if the zone is big enough to show on the screen, and if not, where is the next zone large enough to be visible. It is brute force, nothing too smart about it. Combine that with small data structures and parallel processing to overcome memory latency and that's it.

@pervognsen @theWarhelm @forrestthewoods For plots, it checks if the number of plot items to draw is less than an arbitrary number, then draw all, otherwise do random sampling.

@pervognsen @theWarhelm @forrestthewoods I have thought about how to improve this, but have not come up with a satisfactory solution. You either have a ton of metadata and a hard time when you need to insert a new item in the middle of already existing ones, or you have to do some kind of partitioning scheme. But then you have to decide whether to do it by time or by number of items, and your basic problem does not go away anyway, it just happens some time later.

wolfpld, 6 days ago

@pervognsen @theWarhelm @forrestthewoods What you describe seems to be quite tricky to me ;) But I think I get the general gist of it.

The zones are not the problem though, they are fine as they are. You can run a debug build and it will go happily at 144 FPS, even if the screen is full or razor thin zones.

The real problem is with handling plot data, including CPU usage, which basically does a binary search for each screen column, and it's slow.

wolfpld, 13 days ago

@dougbinks @dotstdy No. That UI is completely broken and I always had the exact same problems you describe.

wolfpld, 15 days ago

@TTimo @dotstdy It stays in the build history, though.

wolfpld, 14 days ago

@dougbinks It's not that complex, though. I always just put the lib/ contents into my projects and that's it. You just need to add those files to the source list. No macro definitions, no fancy compilation flags, nothing.

The only semi-complex thing is the x64 assembly file used for decompression, but it just works, I never had any problems with it.

There is also build/single_file_libs to generate a single source file, but I've never used it.

wolfpld, 14 days ago

@dougbinks Ah, I have the same problem in Tracy, where some performance significant code is not needed in some utilities. As a result, one of the source files compiled with a specific flag gives two different API/ABIs.

I simply provide independent build files for each of the utilities that Tracy provides. You can switch between them in the editor and get the right set of compile flags for clangd, etc.

wolfpld, 14 days ago

@dougbinks Hashing object files seems like a solution where you just have one build file for everything and do no separation.

I don't know, maybe it's some kind of cargo cult that you need to build everything in your project from one place? I wanted to fix this in the Meson VS Code extension, and it was a constant "yeah, but why?", "nobody does that", and so on.

wolfpld, 14 days ago

@dougbinks I believe the current layout of zstd is Yann's original design, before Facebook got involved.

@forrestthewoods I wanted a nice graph like you have, and I know it's possible to get it because I have it in Tracy, but it turns out that... there is nothing that would continuously probe the energy measurements to write out a csv on Linux. WTF.

wolfpld, 19 days ago

@forrestthewoods Ok, I put something together and here's my graph. The measurement is done with RAPL over the whole CPU package (supposedly).

wolfpld, 18 days ago

@amonakov @forrestthewoods @castano Googling "repl" or even "intel-repl" does not yield any worthwhile answers. It is not a well-documented topic.

The examples for perf I found produced a single energy consumption value for the given time, and I wanted a graph. There was not an out-of-the-box solution that I could use for this.

While I found some random utilities on github (most were 10 years old), turbostat was not one of them.

wolfpld, 18 days ago

@miblo @amonakov @forrestthewoods @castano I wasn't looking for github specifically, I was looking for energy monitoring in general, so that's not really an issue.

There are all these random little utilities that were maybe announced on some mailing list 15 years ago, and you have no chance of finding them unless you know exactly what you are looking for.

wolfpld, 18 days ago

@miblo @amonakov @forrestthewoods @castano The user-friendly GUI applications that monitor the system don't even show all this information that is available.

The system monitor in KDE has fields for GPU usage or GPU memory allocation, but these fields don't show anything. I have to use nvtop to monitor this data. I don't understand why these things can't just work.

There's so much to improve and so little time.

@pervognsen This is exactly what I did on my desktop when KDE 6 was released in late February. No regrets.

Modern computing is mostly done in the browser, which is platform independent. For programming I use VS Code, just as I used to on Windows, where the alternative of MSVC got worse with each new release. For smaller things I was using WSL anyway, because the Windows application scene has died out. So why bother with all the bugs in Windows 11 that will not be fixed for literally years?

wolfpld, 23 days ago

@pervognsen Things that figuratively blew my mind:

• You can copy multi-gigabyte files instantly, because copy-on-write is a thing in XFS.
• You can see the bugs you experience being tracked and eventually fixed.
• The file browser is actually useful, I can open a directory with a bunch of mp3 files and not have to wait half a minute for the browser to unfreeze.
• Things just work. Games, Davinci, Reaper. Unbelievable 20 years ago.

wolfpld, 23 days ago

@SonnyBonds @pervognsen I did this some time ago and I think I used yabridge. The windows-only plugins worked flawlessly.

By the way, on Linux you can set low-latency audio routing for Reaper with a single env variable for JACK. On Windows, you have to use a separate ASIO driver that hijacks the audio output from all other programs running on the system.

@TodayInTwitter @Hipska @SimonCHulse What if Twitter required you to post something once a week, or your account would be deleted and available for anyone to claim? Say, to argue that daily active users are through the roof?

It's Elon's service and Elon's rules. No one is obligated to be held hostage and play his game.

If the kind of scams you describe were to become widespread, Twitter would become an untrustworthy service, even for people who don't care about it right now. That's a win.
