I recommend https://eleshop.eu/jbc-bt-2bqa-soldering-station.html

The handle is so light! Active tips! Heats up in 2 seconds. Goes to standby mode when you put away the handle to save the tips.

There's even a lighter compatible precision handle that you can buy.

Luke Gorrie posted a bunch of Twitter threads where he compare the sizes of soldering handles. Can't find it now but https://github.com/lukego/soldering might lead you to them.

I'm still using Sourcetrail daily for inspecting C++ codebases. Works great. I paid for the first beta and was very sad that the company was not profitable. It really is a great product.

Notes on systems programming. Not that many posts but I've reached the HN frontpage on two occasions.

Rico Mariani gives his opinions on the future of system programming languages.

His main point is that C++ with EH introduces too much bloat; that the opaque error handling combined with no compiler assisted checking hides bugs; and that you can't write C++ codes from "the books" since it leads to more bugs!

With Rust you can write it like in the books!

"Modern C++ has so many hazards and is so costly that I can't but view it as anything less than a total failure in the systems space. I can't begin to tell you how disappointing this is to me. "

=== Cut needless words ===

The article references Covingtons How to Write more Clearly, Think More Clearly [...] Powerpoint presentation [1]. I highly recommend it!

A fun part in that presentation is when Covington, in a series of steps, revises this sentence...

“One of the best things you can do for yourself to improve your writing is to learn how to cut out words that are not necessary.”

..Into this one:

“To improve your writing, cut out unnecessary words.”

OPs article calls for more words to provide context. But by revising you can often cut the length in half.

[gcc/gdb/LLVM outsider here]

If someone is interested in what's being done to improve LLVMs debuginfo, here's a talk by Djordje Todorovic from two years ago: https://www.youtube.com/watch?v=GpMLt1oecOk. It's about tracking dwarf locations for variables by keeping around information from the parent frame. According to that presentation, at least that work has been progressing.

Has anyone had a chance to read this yet? Is it a good complement to Brendan Greggs and Denis Bakhvalov books?

What more besides the ideas in Richards ACM Queue article are present? https://queue.acm.org/detail.cfm?id=3291278

How does his KUTrace Linux kernel patches differ from the existing tracing infrastructure? This talk [1] seems to suggest that the reason his KUTrace is so fast is because the other tracers collect more information.

How does the tracing capabilities here compared to what the Windows WPA subsystem can offer? Does it have less overhead for collecting such traces?

Sampling profilers like Superluminal claims to be able to recognize very small delays. For how many cases do you need something like KUTrace and when is Superluminal enough?

[1] https://www.youtube.com/watch?v=UYwWollxzAk I felt a little uneasy watching it due to Richard being so disagreeable to anyoone asking him questions
