I'm the author of the fastest .NET version. Ask me anything about the implementation. The code is very short and simple.

Author there. Nothing really matters other than `ProcessChunk`. Don't you think I kind of know what I'm doing with these numbers!?

This is so awesome and made me smile a lot! I have the physical book (expanded 3rd edition) but it's big and heavy. I could not take it with me when I relocated to another country with just 2 suitcases. But I miss it so much. In additi

It takes 330 seconds on a machine where the top OpenJDK version takes 5.75 secs and my .NET version takes 4.8 seconds. However it's just several lines of code and I used ChatGPT as a fun use case for how long it would take to have some

Not only sales, but market share/power. Imagine if J3QQ4... did not work for Windows 98... Linux on Desktop would be already perfect 20 years ago.

YouTube and InfoQ are free and have lots of great content. .NET is probably lacking good content. Yet many things from Java are directly applicable. E.g. on benchmarking & performance, there are true gems on InfoQ by Gil Tene, Martin Th

Another course on another platform that overpromises and underdelivers - it is just noise. I did not want to discuss this subject beyond expressing some surprise. Fraud is a too loaded word, but this fits perfectly here: https://

It's so appalling that a paid content could be that bad. For me the first benchmark that was doing nothing in both cases is as shocking as the second. But the thing I wanted to highlight is that the blog author is a real authority on s

Hm, last time I tried 3 years ago paper mails were their only channel (after opening an account online). They were so past century. If they do anything with this TLD before improving their basic banking platform/UX it will only prove t

Having Proxmox-based homelab setup I was waiting for quite a while for Linux containers support so that Docker in LXC containers just works. It was quite inconvenient when even a pull for a simple image freezes. Hopefully now a docker-compo

There are 16 "talks" mentions as of this writing, yet I want to reiterate how important, insightful, useful and fun his talks are and watching them have been. They move a listener to a (next level). Good luck, Rich! Have a nice ti

Branchless or not in this case, it still touches memory in not so good pattern. I found that a significant speedup of a classic BS could be achieved by switching to vectorized search when the remaining range has a width of 3-4 SIMD lines (o

When I was looking for a name for my now-archived distributed actors system based on Redis ( https://github.com/buybackoff/Ractor ), the choice for Redis+Actor was between Reactor, Redactor and Ractor. Then I found a re

Having dealt with several data parsers I would like to somehow estimate how much electricity is burned globally just for lazy implementations. E.g. in .NET non-devirtualized `Stream.ReadByte` is often one of the hottest methods in a profile

Essilor 1.7 aspheric lenses cost me 235 euros each. An alternative is Japanese Seiko and German Zeiss. Essilor is probably the cheapest of them. Good lenses cost much more than a nice Luxottica frame and are covered by insurance in France.

I would change to edit MT code. It usually starts with a clear picture in mind... But even one's own code quickly becomes cryptic without lots of comments and hidden assumptions. I used to have this picture printed and put above a se

And Portugal should cancel Abramovich citizenship, who is one of the closest to Putin oligarchs. My guess is at the time when he applied for citizenship he knew about what was going to happen, at least in general. Now as a citizen of EU mem

Even with ZFS you still have to wait for RAM to dump, haven't you? And it will freeze at least for the dump write time. Do they have CoW for container memory? But even if they had, the RAM snapshot needs to be written, but without free

LXC via Proxmox is great for stateful deployments on baremetal servers. It's very easy to backup entire containers with the state (SQLite, Postgres dir) to e.g. NAS (and with TrueNAS then to S3/B2). Best used with ZFS raid, with q

It could automatically load SSH keyd to Putty Agent on DB opening. Nice convenience for e.g. GitHub keys. Learned about it accidentally after long usage. It performs great for core functions. I store the db in DropBox and the second factor

The problem with methods such as GetCPUCyles or GetCPUCoreId is that .NET delegate calls are never inlined. Unmanaged calli calls are not inlined either. PInvokes could be inlined but have their own overheads for managed<->native tran

I would rather think machine translation and learning foreign languages should be better in general. But that is probably a C2-level subtlety, so if a non-Russian was writing that I could understand. I imagine a situation: EN copywriter a

It's worse than that, the first thing that I scanned in the article is if he is alive. A title like that without a pre-defined context more often, in my native Russian perception, could mean much worse that just leaving a company. I&#x
