This can be very simple: 1. A bored male person opens the site and types the first thing that comes to his mind in the search box. 2. Website records this as a new search and suggests it at random to new visitors. 3. Curious people click it

I have struggled explaining what the auras looks like, but for me they look like confetti, in particular the shiny stuff used to celebrate sports championships. Sorry for piggybacking on your fascinating account, but unless you experience i

When Apple launches a new phone, they manage to keep “old” apps compatible with the new hardware/OS. After that, developers are no longer allowed to upload such apps, even though they would work perfectly fine. It would not be a big ha

The article mentions the reduction, not beginlevels of the substances. It turns out that the reduction during the test period is about 30% (for at least one of the substance categories). A meaningful reduction for sure, but it should be int

Hi, you are ignoring the second point, and for the other two points you are referring to particular extensions of quicksort. Quite possibly you can extend quicksort similar to how timsort extended mergesort, but if that was commonplace nobo

We have Word documents for requirements and (manual) test cases plus a self-written audit tools that checks the links between them, and converts them into hyperlinked and searchable HTML. It’s part of the dayly build. We are mostly happy wi

I can recommend going beyond the source code and check the checkin comment or bugtracker entry of the code you intend to change (once you found it). If the code is strange or arbitrary there is often a reason, and knowing that will improve

I sat in front of those things for the first 10 years of my programming life. I am not nostalgic for them. If you guys are so into retrocomputing, I might have a teletype for you in the attic. Don’t forget to bring your noise cancelling hea

Yes, pity that is not in the video.

Doesn’t that imply that the incoming photons are spread out over the entire mirror, several meters?

I see 8. With the smaller horizontal ones likely coming from one of arms of the secondary mirror (check the “selfie” image). The linked video is nice, by the way.

> companies would have to sell their parts for little enough that you could buy all the parts for a whole new machine Something like that could be a law. We could allow them a little markup to cover distribution cost, but one could argue

But they don’t explain why I was logged out. I did not log out myself. Or is this “logged out” in the sense that I did not have their app active at the time of the disruption?

It is avoidable by using locks like you mention, the article actually says so, but it causes an ABI change. They go on to say that this makes it undesirable, but compared to what alternative exactly?

This is a Phd thesis. I think this is a great read, to see so many algorithms discussed that are not really GPU friendly.

In a Wondrium lecture on genetics and evolution, this question was also discussed. A compelling (but unproven) explanation for our “age limit” is that any genetic trait that improves your chances before reproduction at the cost of your chan

How about a bluetooth enabled covid test? The digital pregnancy test really isn’t complete with a radio transmitter if you ask me. https://hackaday.com/2021/10/17/electronic-covid-test-tear-d...

The approval is likely a big issue. The manufacturer can buy the approved strips, and claim that they are validated and accurate. How much paperwork you need to submit for the digital part is an interesting question. I would expect you do n

My father in-law once asked me if one could charge a phone using body heat. I did some calculations but the thing is that if the heat difference is small, the conversion efficiency goes down too. As others suggest, insinuating the source is

An actual Turing machine maybe? I’m someone built one by now.

I agree that for standard hash tables this won’t work. However, I recently read about “Ideal Hash Trees” [0], that preserves the entire hash. That design also requires all bits to be “random” because it lacks the usual prime division. [0]

Is there a category of hash functions that hash a 64/32 bit input to exactly 64/32 bits output, such that all inputs are uniquely preserved? This could be an interesting property for a hash table of integers, because a hash match

It is not so much my intuition but the intuition of the language designers. I would prefer euclidian division personally.

Careful what you wish for. What should -7 / 2 return? -3 kind of makes sense, because 7/2 is 3. It also desirable to have the remainder consistent with the result of division, such that x = d*r + mod, where r is the result of divi

I would say that keeping the checks in runtime for release builds is the smart default. For most usages, removing the checks in release builds only adds security holes without measurable impact on performance.

I can second this. C# has had AOT and JIT compilation for years, and the JIT is almost always faster. It is really hard to predict where to optimize, devirtualize and inline if you don’t know the runtime behavior. (Note AOT != ngen, I am ta
