Counterpoint: Natural sorting likely will be orders of magnitude slower sorting than ordinal sorting. For most situations, the better solution is storing the index separately to the name in another column or in metadata. But for some stores

I hope this is satire? Just in case it's serious or semi-serious: It's utterly ridiculous to worry about 10k date problems given we first have these: 2038 problem ( Signed unix time overflow ) 2069 problem ( strptime() parsing ) 2

I've seen far too many IVs statically declared as "<Product>IV" in my lifetime. Bonus marks for when the key was also "<Product>Key".

Neat puzzle. My first wrong answer was an international spelling issue. It would be nice if it accepted then silently corrected based on equivalent international spellings, but I can also understand why it doesn't, sometimes it might b

LLMs ought to be good at generating simple substitutions too, but they're not: https://claude.ai/share/9495246c-b77a-496e-8643-dbc5ec58dbcb It tries but it fails to both generate and apply a simple substitution. I

Sparklines are not bar graphs, they're lines, hence the name. If you have a copy of Tufte*, you can find them on page 171. Tufte has written up a history here: https://www.edwardtufte.com/notebook/sparklines-histor

So much continual effort wasted when for over 20 years we've had XML. XML still works well as a configuration format. Is it verbose? Very much so, but it ticks all the boxes: - No ambiguity - Typed - Quick to parse - Has Schemas that a

We have a few such odd arrangements, such as the "London Bus Museum", which isn't in London but is in fact entirely within a completely different museum, the Brooklands museum. Operationally independent, although they have be

Isn't this what Jekyll solves? Posts are all written as markdown, styling and layout are centralised with layout HTML pages and CSS. I believe indexes can be auto-updated via post metadata. And it's all static pages once generated

I haven't, I wasn't aware of that attribute. I would gratefully accept a PR with such a benchmark case. Edit: I've now tried it, and it reduced overhead a small amount. (e.g. Average 7.5 ns vs 8 ns for the 10-byte array )

The comparison isn't to prove that .NET is always faster than C in all circumstances, it was to demonstrate that the advice to call out to C from .NET is outdated and now worse than the naive approach. Can C wizards write faster code?

Thank you, it was indeed a "garbled quoting" of that article. I am generally terrible at explaining things. Trying to improve my ability to explain things was part of my motivation for taking up blogging.

Outside of the 10 elements case, I don't think it's an overhead issue, the overhead is surely minuscule compared to the 1GB of data in the final tests, which also show a large difference in performance. I suspect it's that th

I tried that but cut it from the code because it had the same performance.

A more meaningful adventure into microbenchmarking than my last. I look at why we no longer need to P/Invoke memcmp to efficiently compare arrays in C# / .NET. Old stackoverflow answers are a dangerous form of bit-rot. They get pi
