I've played Noita ( https://noitagame.com/ ) for quite a bit, and lately it clicked to me, that the core mechanics of the player and environment come from Liero. Though Noita is a single player rouge-lite, it has wands i

TIL :) thanks, I misunderstood that part.

Interesting note on the NOW() (or CURRENT_TIMESTAMP), they are equivalent to transaction_timestamp(), which means - start time of the current transaction. So, if you'd insert multiple items in a single transaction, all of them would en

> time goes backwards is DST Only if you deal with timestamps that don't contain timezone information. With TIMESTAMPTZ in postgres it's transparent, you don't have to do anything specifically to manage DST.

Depends on the usage. Commonly available "legit" PRNGs have uniform distribution, even over long range of numbers. Wikipedia has a list of interesting tests you could do to confirm you PRNG: https://en.wikipedia.org&#x2

What's wrong with using UUIDs for things that are commonly used every nanosecond? It's still improbable to get 2 UUIDs for identifier for the same "thing" in the system, even if you generate billions of them per second.

I'm not looking at the keyboard, but I often move my right hand to click brackets or comma with index/middle finger. Takes muscle memory.

The rant in the middle is very dismissive over voices against in the discussion, and that makes me agree with OP.

But that's on a single RAID in a single location. You'd probably need at least one failover, and backups for that as well, if you'd like to target higher availability / durability. S3 keeps multiple copies in multiple ge

That's a pretty nice solution to a gripe I have with programming and typing. This year I've practiced touch typing for the first time in 10 years, and turns out it's such a chore to use touch-typing while programming! My righ

IIS (Microsoft / Windows Server HTTP server) supports a technology rival to CGI called ISAPI, which was deployed using .dll files. .dll is a Microsofts' dynamic library standard, commonly produced by e.g. C/C++, but also by .

I've got 2 external HDDs in ZFS mirror, cheap consumer disks. One of them is perfectly fine, second one started having occasional read or write errors, which is not great. With regular weekly scrub I hadn't had any data issues ov

I had similar idea, but in the end I've gone a different path: I've got a USFF PC with 2 external HDDs as NAS, and raspberry pi to keep always on stuff. I used to keep the PC up most of the day, and get it to sleep on schedule dur

Though you don't need most of the OS - you may run bare bones containers with just a statically built binary inside the image, e.g. it's possible in Go.

Interesting note - there's already standard representation for truncated sha2 - SHA-512/224 and SHA-512/256, but unfortunately no with output length of sha1. Even more interesting thing is that those truncated representations

That's a very good point!

Yes, but the REST vs SQL forces a specific API for changes. REST - update/delete a specific record. SQL - update/delete based on a filter, or a query result. I can do `set a = b` for all rows in the table, which may be needed inte

That's only if you use immutable strings. In C# or js (and probably in others as well) you can use some form of byte arrays / buffers, and overwrite their content after use.

There's a pretty important note in the remarks, that you should not use SecureString in new code, as it only shortens the lifespan of the plaintext in memory.

Why not just accept SQL? It's a matter of contract. With REST APIs you specify a contract, it gets robust with time, and other software can expect only what's in the contract. SQL allows you to run arbitrary functions over data in

You can configure ZFS to use sha256 or sha512 for checksums. Sha256 is the default for datasets with deduplication.

It looks like you're sorting the whole file, while python implementation sorts only unique values.

If you fix commonly occurring bugs, you're left with rare bugs - and there may be tons of them in mature codebase. For legacy systems with dedicated operators, it may make more financial sense to teach users a workaround to a bug, than

That's exactly my problem today - I have some old PCs repurposed as homelab, and they require some cron jobs to keep them in check - like forcing modules, or keeping the fans from whining. Without any MTA, it's such a chore to lea

This might be an overkill, but you can host internal domain using public DNS. I've got a domain, and I've added multiple A records pointing to IPs of servers in my 192.168.X.Y NAT. This has a downside thought, that with short enou

At my $dailyjob we (kinda unfortunately) went with tons of repositories and libraries upon libraries, and the only sane way for me to make changes across multiple repos is combining them into single build locally. In .NET it's not that

It's not only that debugger is closed-source - if you try to run non-MS provided build of VS Code, the .Net debugger would decline to start. That was very surprising, after installing VS Code on ubuntu from some default package.

Disclaimer: I may be absolutely in the wrong here, as I may be missing some fundamental economics knowledge. From my understanding, inflation is not really a property of the currency, but a property of market in which given currency is used
