JVM Profiling in Action
We'll use async-profiler and flame graphs for profiling. To simplify the process, we'll run the code using JBang.

All my favorite tracing tools: eBPF, QEMU, Perfetto, new ones I built and more
which can output in a format understood by Brendan Gregg's flame frames (https://www.brendangregg.com/flamegraphs.html)
But that's not quite the kind of tracing you're talking about. We also built a printf-style interface to our recording files, which seems closer:

Recap of Werner Vogels' Keynote at re:Invent 2023
Strategies included discontinuing or resizing underutilized services, transitioning to more cost-effective solutions, reducing the current resources to the amount of resources that we need for our application, and conducting detailed analyses of computing resource utilization through tools like flamegraphs. This detailed scrutiny helped identify and rectify significant cost-driving areas, such as garbage collection and application configurations.

So if you can make your tool eat whatever https://github.com/brendangregg/FlameGraph is fed with you're going to support a lot of existing tooling across OSes and languages.

Introducing Flame graphs: It’s getting hot in here
“Flame graphs are a visualization of hierarchical data, created to visualize stack traces of profiled software so that the most frequent code-paths to be identified quickly and accurately.”

Using SVG to create simple sparkline charts
SVGs are amazing for interactive visualisation too. Like Flamegraphs: https://www.brendangregg.com/flamegraphs.html

Good example of using flame graphs to speed up java code (50x improvement)
This may be a good example of the application of a flame graph but it is not a good demonstration of flame graphs; the graph is nearly incidental. The source has an actual explanation.

Intro to PostGraphile V5 (Part 1): Replacing the Foundations
A profiling flame graph from Graphile Crystal (a precursor to Grafast) using GraphQL.js' executor (each tick is 1ms, total: 29ms). As we removed more and more responsibilities from GraphQL.js, we ended up only using it for output. Replacing this final responsibility with a custom implementation in Graphile Crystal itself, we reduced execution time for this query down to 15.5ms (effectively removing the majority of the yellow portion of the flame graph).

Conflicting info on Dark Mode removal from Firefox for iOS
Users are complaining that the latest Firefox for iOS update has removed the "Dark mode" option from the menu:[1]
> I suffer from Diabetic Retinopathy and hence photophobia. To me, this removal is an Accessability issue.
A forum moderator who's in touch with the developers said days ago that this is an experiment affecting half of the userbase:[2]
> The team is currently doing an experiment. Since March 15, 50% of users no longer see Night Mode switch from the hamburger menu. We're using this experiment to monitor and evaluate the impact of removing, so it'll be hugely valuable to hear your feedback around this feature. Thanks!
However, Mozilla's iOS team manager doesn't know about this huge experiment and think it is a bug:[3]
> Moving Focus into the Firefox repo so it can get more love and support. This happened last release and may be the culprit that broke dark mode. We're looking into this right now.

Platform issues which disadvantage Firefox compared to first-party browsers

last known version to work on ios 12?
https://github.com/mozilla-mobile/firefox-ios/commit/686d36402c6a956f460abafc8f1fe19a7887a2f3 landed in v38, so it looks like v37 was the last to support iOS 12.

Why Firefox shows unsecure connection when using reader view
When you use Reader View, Firefox parses the text of the webpage and loads it as a local page. It isn't supposed to show a red slash, though. Reader Mode shows a neutral icon (📄) on the desktop version. Please open this page and click on New Issue to report this to Mozilla, and then share the link with us.
