The point is they can't tell.

Mineral oil is what people use these days, but it is much less funny. In practice, any oil will do, although olive oil is not suggested - smells nice at first, but will break down over time.

You can still do this with any computer, by the way: just submerge the entire board in motor oil. Slightly smelly and might make a mess, but absolutely workable.

> The idea that only nerds care about the cost of things is... absurd.

For hardware purchases, laypeople may go about it the other way from what nerds would do: instead of deciding what they need in terms of computing power and memory, and then finding a cheap offer for that, they just decide how much they want to spend, and then buy a device at that price point irrespective of its performance characteristics. If you shop like this, and would have purchased anything but a rock-bottom low-end device two years ago, prices have remained stable.

One obvious use case is edge computing, such as in industrial applications that cannot tolerate the risk of a network link or cloud service going down. Even embedded use cases are possible, such as an image classifier model in a security camera.

In German, it's also extremely annoying that even common compound words will not be suggested. Google Keyboard has somewhat improved here, but FUTO Keyboard still drops the ball on this completely.

Yes, but Hetzner is not "some low-end provider". They have proper, high-quality datacenters with all the redundancy you want, excellent connectivity, great service, and much better privacy controls than any American company would be legally able to provide. Hetzner also offers instant scalability and has Terraform and Ansible support for infrastructure automation.

We have some VMs on Azure and some on Hetzner, and the latter have much better performance (especially since they give you basically infinite IOPS, which matters a lot for your database) and connectivity (especially lower latency).

The large hyperscalers were ever only worth it if you need/want all the additional PaaS infrastructure they provide, like Lambda, SQS and so on.

Not only is "arguments are evaluated left-to-right" less easy to formalize than you think, it would also make all C code run slower, because the compiler would no longer be able to interleave computations for more efficient pipelining. The same goes for "expression is [only evaluated once]/[always evaluated twice]".

Of course the developer is navigating a minefield every time they use volatile, that's why it's called "volatile" - an English word otherwise only commonly used in chemistry, where it means "stuff that wants to go boom".

Yes, this surprised me as well. Credit card and Paypal information should give the police everything they need to identify the criminal (in a way that's much more simple and reliable than via IP address, which may be obfuscated via a VPN or similar). Why not take it, it's free?

People are already not using libraries because they'd rather rot their brains on TikTok than read a book. (Also, for information lookup, the internet and search engines exist, and have for a while now.) This has no actual causal relation.

This is quite amazing. The quality of the created palettes is surprisingly good.

For the fourth iteration (guarding against phantom blue from shadow pixels), I wonder if it may help to also take into account how close the pixels in each cluster actually cluster together in the actual photo. (None of the heuristics used here seem to be interested in the position of the pixels at all, only in their values - as-is, it seems one could sort the photo's pixels before running the program and get the same result.) Actual objects usually form connected areas, whereas at least in the fruit image, the phantom shadows are spread across the entire photo in largely disconnected chunks.

You can of course take a SQL dump that is version-independent, but if you're serious about creating backups, you want to take backups of the actual on-disk format of the WAL, because that's more efficient and also the only practical way to get point-in-time recovery. (For the efficiency, you could alternatively also take ZFS snapshots, which will work independently of the Postgres version, but those also don't give you PITR.) The WAL format is a Postgres implementation detail and therefore tools wanting to read and write it need maintenance whenever the format changes (which can happen on major version releases).

    (I'm kidding, but I'm sure someone has a pie-in-the-sky geoengineering startup 
    about to disrupt topography using either AI, blockchain, or both.)

Well, there was that plan to use scores of nuclear bombs to alter the geography of Egypt in such a way that the Mediterranean could be drained into the Qattara Basin [1]. I think the story is somewhat well-known now, but it proves, at least, that pie-in-the-sky geoengineering startups are not a phenomenon unique to the 21st century. And given that nuclear bombs essentially were the blockchain of the 1950s, that is altogether unsurprising.

For the use cases outlined in the OP, a 36% performance gain for an optimization that complex would be considered a waste of time. OP was explicitly not talking about code that cares about the performance of its hot path that much. Most applications spend 90% of their runtime waiting for IO anyway, so optimizations of this scale don't do anything.

Funnily enough, in the blog post you linked Scott Alexander also ruminates about how he never previously questioned journalistic attempts to dox Satoshi Nakamoto.

> Signal insists on using your phone number too, refusing user ids or anything that will make analysis hard.

That is no longer true, you can use user IDs now.

For the other problem, you can enable self-deleting messages in group chats, limiting the damage when a chat does become compromised. Of course, this doesn't stop any persistent threat, such as law enforcement (is that even the right term anymore?) getting access to an unlocked phone.

Great tool that wrote the blog post in the OP also, so it's quite versatile.

Right, but I think that the Recycle Bin is exactly what is causing the issue here. Users have been taught for decades that if they delete something, it is not really gone, as they can always just go back to their Recycle Bin or Deleted Items folder and restore it. (I have worked with clients that used the Deleted Items folder in Outlook as an archive for certain conversations, and would regularly reference it.)

So users have been taught that the term "delete" means "move somewhere out of my sight". If you design a UI and make "delete" mean something completely different from what everyone already understands it to mean, the problem is you, not the user.

Even in MongoDB, you can can index `null` values, so I don't understand in what database system this would be a problem.
