#profiling — Public Fediverse posts

After your remote debugging connection is established, it’s time to solve real-world problems. In this second part, Christoph Sterz demonstrates how to use your remote debugging setup to act as if you were running the code directly on your desktop.

Christoph dives into a real-world scenario: a ship navigation app that crashes on the target device. You'll see how to catch a segmentation fault, interpret stack traces, and identify common pitfalls like lambda lifetime issues in Qt. He also wraps up with QML #profiling, showing you how to pinpoint performance bottlenecks and slow frames directly on the #hardware.

This video covers:
- Remote GDB Workflow: Using target extended-remote to catch crashes in real-time.
- #Debugging Case Study: Solving a classic lambda reference error that only crashes on hardware.
- QML #Performance: How to profile startup costs and runtime frame rates on the device.
- Safety Warning: Best practices for enabling #QML debugging in secure environments.

A woman was pulled over at gunpoint on a freeway.

Shocking no one, she’s also Black and Flock was involved.

They say now it was a data entry error. I highly doubt that was by a person.

Bitte nenne uns eine Quelle, aus der hervorgeht, dass keine Daten abfließen.

Es fließen Daten über die App und Laufzeitumgebung ab. Damit ist die Aussage hier, dass dabei "keine Daten der App fließen.", falsch!
Metadaten sind auch Daten. Es wird bekannt wann in welcher Umgebung eine App wie oft von genau einem Gerät genutzt wird.

Логгер в топе VTune: как найти строки, создающие нагрузку

Профайлер показывает write() и worker файлового логгера среди верхних стеков. Однако системный профайлер не знает, какая из тысяч строк вывода в лог породила нагрузку. Отключать логирование совсем — ужасное решение. Как же связать файловый ввод-вывод с конкретными строками вывода в лог, каналами и backend?

Update: I made a new, simpler performance profile recording of my "every 15 seconds or so, Firefox freezes up for roughly one second" bug report at https://bugzilla.mozilla.org/show_bug.cgi?id=2056048

It seems like it's caused by… an incremental CC and GC running?! :blobsweats:

I'm starting to really like Firefox's built-in profiler, that thing is black magic. How the heck does it get perfectly symbolicated profiles everytime without me needing to install gigabytes of debuginfo packages?

Since I use the "dnf debuginfo-install" command so often (instead of debuginfod) to cleanly install debug symbols for apps and libraries on #Fedora, which lets me get meaningful backtraces for crashes reporting or sysprof performance profiling, I figured I might as well request the ability to autocomplete filenames with Tab: https://github.com/rpm-software-management/dnf-plugins-core/issues/623

It seems I have found a sneaky memory leak that occurs when you reload webpages with @WebKitGTK: https://bugs.webkit.org/show_bug.cgi?id=319590

That might explain why I kept running out of RAM way too easily when using Epiphany with a dozen tabs or so.

I suspect fixing this should significantly improve Epiphany's survivability in the wild, as well as long-running GTK apps that embed a webview (like email clients) :blobcat:

The thing about #profiling, #canvassing, #datatracking at large is that not only can #ad providers target and manipulate you individually - to the point where it feels almost eerie how they know everything you want and need, confirmation biases and all - but advertisers can pinpoint where to advertise illegal and illicit services without the general consumer being exposed to it.

JetBrains IDE: будущее не за горами

Если вы хоть немного следите за AI coding, то наверняка слышали новую мантру: IDE больше никому не нужна. Все «вайбанутые» живут в терминале, запускают Claude Code, Codex или OpenCode и уверенно объясняют, что профессиональная среда разработки — это пережиток эпохи, когда код писали руками. Agent-у хватает самых простых инструментов: grep , bash , edit и пары хороших prompt-ов. Сложные интерфейсы, UI-инспекторы, рефакторинги, дебаггер — всё это выглядит как пережиток прошлого. Открыл терминал, написал задачу, получил diff. Кажется, человечеству IDE больше не нужна. Или всё-таки нужна? Тут как посмотреть. JetBrains в этой картине обычно достаётся роль динозавра. Компания много лет задавала планку того, как должен выглядеть профессиональный инструмент разработчика. Но когда индустрия сместила фокус с IDE на agent-ов, предложенные JetBrains AI Chat (ex. AI Assistant) и Junie выглядели не как новый тренд, а скорее как попытка заскочить в уходящий поезд. Но у тезиса «IDE больше не нужна» есть слабое место: он смотрит на IDE только глазами человека. А что, если следующими пользователями IDE будут не люди, а agent-ы? В компании JetBrains с закатом IDE, естественно, не согласны и предлагают своё видение: среда разработки как набор инструментов и знаний о проекте, доступных AI Agent-у. Команда

I'm considering posting regularly my "GDPR diary", i.e. an account of all the companies and data brokers I send cease-and-desist communications to, related to unwanted marketing, spam, promotions, etc. It's a whack-a-mole of course, but it has become my guilty hobby (and much easier now with AI tooling). TBH I also consider this a form of civil duty: if everyone does the same, very soon predatory marketing would become too risky to be profitable.

I send usually 1-2 of these emails (or letters) per week. And so far it's kind of working, i.e. when I home in on a target, usually the annoyances stop.

Dont feel bad using a firm language and threatening legal action, it's your rights, it's your self-defense against this Satanic practice, and I'd argue its' your duty too!
