If you get the ? from rust in addition to the option, then it’s suddenly a lot more convenient. It will do `if err != nil { return err; }` in a single symbol. There’s also convenience at the returning side. You can always just return the er

To be honest, I actually agree that Dijkstra's argument seem a bit one sided. It's also interesting to see the argument in your linked article that offset and index doesn't have to be the same. If I get the root of the argume

There are arguments for why 0-based indexing is _better_, unrelated to pointer arithmetic. https://www.cs.utexas.edu/~EWD/transcriptions/EWD08xx/EWD831... > we had better regard —after all those centuries!

I worked on a game where we added a "fairness" factor to randomness. If you were unlucky in one battle, you were lucky in the next, and vice versa. Mathematically you ended up completely fair. (The game designer hated it, though,

Interesting to see an alternative approach. I struggled a bit to understand the explanation on github, but eventually got to something that made sense. It would have helped me if it said up front that - 0, 1, N and Y pass the input signal o

Capitalization is ignored by the compiler. So you can call it REPEAT, repeat, rEpEaT and so on. Same for variable names, functions, etc.

I don't know, but anecdotally, I still use it for work, but no longer for personal chats. It also seems like someone at Slack is tasked with driving up engagement, because I get these "Your team is missing you" messages from

Another version that's useful is this ASCII version: https://gabmus.org/posts/raspberry_pi_pico_pinout_in_your_te... I keep a slightly modified version of it as a top comment in my main C file in every pico projec

Thanks! I've been using pinout.xyz quite a few times; maybe you should link from there to the pico versions so it's easier to discover?

Thanks! So I guess the best recourse then is to resize the table? Seems like it should be part of the analysis, even if it's low probability of it happening. I haven't read the paper, though, so no strong opinion here... (By the w

One thing I don't understand from watching the video, is what happens in the (very rare) case that you get collisions all the way down the funnel. I assume this is related to the "One special final level to catch a few keys"

The UX on MacOS is so bad here. First, a notification prompts you to enable Apple Intelligence. When you dismiss the notification by clicking the "x" in the corner, it instead opens the system settings and proceeds to download som

I agree with OP that it's unnecessarily confusing. A "method" is a procedure. The floating point number is the result of that procedure, not the procedure itself. "Decimal" implies a ten based system, even though it

How much of luggage handling is the airline vs. the airport crew? I had assumed it was mostly the latter.

There's also MPU in even simpler/cheaper MCUs. For instance, ARM Cortex M0+ sports an MPU, and this architecture is used in STM32C0 ($0.24 in bulk) and RP2040. I have no idea how the landscape looks in general, though.

This is because of relativity and the fact that there's more force at in the valley than the mountain. https://en.wikipedia.org/wiki/Time_dilation

I also have mixed results with using the iPad as an external monitor. It works every time, but it's orders of magnitude more fiddly than an actual monitor. Exposing it as a monitor sounds like a much nicer interface, although I don&#x2

And just to spell it out: Fewer payout means fewer resources to spend on further operations. So I would absolutely think that the criminals care if there is an actual ban.

I never knew these were actually 90mm, and not actually 3.5in. Surprising, since I'm in a metric country.

I just not sure why they put in the "Angstrom symbol" to begin with. If you do, then why isn't the "meter symbol" (m) also represented? Fortunately, it seems like it's marked as deprecated: https://e

It goes 90000..9FFFF then 100000..10FFFF. The latter should have been A0000..AFFFF. So the author is using hex for the last four digits and decimal for the remaining ones.

Because a hash is (by definition) a one-way function. You need to be able to go the other way for incoming ids.

I'm actually working on encrypting database keys like this, and I opted for a string ID with "url safe" base64. It avoids the ambiguity of looking like a UUID when it's not, and I prefer "o3Ru98R3Qw-_x2MdiEEdSQ&quot

You would still use a secret key, so it's impossible for the end user to decrypt it.
