Action which I find much more useful than Back is Up. I’m always annoyed when someone hands me their Android to do something and I need to go through 10 screens hitting Back instead of Up. I almost never want Back. I want Up. This is also reflected in my use of Finder on Mac e.g. where I often hit Cmd+Up, but never Cmd+Left.

A similar warning could be enabled in GCC using the flag -Wsign-compare.

In this case more important than any runtime overflow/underflow checks is the fact that the compiler will check that comparison operands are of the same type instead of inserting an implicit cast. Instead the programmer is forced to insert an explicit conversion like .try_into().unwrap(), which clearly suggests the possibility of an error. And if the error isn't handled, it will panic.

Which is why the Rust compiler itself uses a non-cryptographic hash, which takes just 3 x86 instructions and can work on 8 bytes at a time: <https://github.com/rust-lang/rustc-hash/blob/master/src/lib....>

Given that shutter sounds are produced, I'd guess the shutter is opened[1]:

Most do. Some, like Nikon Z8 and Z9, don't.

You’re right. I misremembered. The term is “shutter life”. Same result though.

Does it affect RAW photos or only JPEGs?

You’ve just compared a densely populated city with a sparsely populated state that’s several times the size of the country the aforementioned city is located in. And then started talking about highways.

In my opinion, the best way to interact with ETW is through DTrace. Microsoft’s GUIs like WPA-Xperf are so buggy and unreliable that using them feels utterly futile. DTrace on Windows on the other hand is very usable.

No. I mean getting drenched, when forecast predicted no rain. 1mm isn’t really noticeable by humans.

yakubin — Mon, 04 Dec 2023 18:49:21 +0000

Absolutely. 15 years ago I could reasonably trust forecasts regarding whether it’s going to rain in a given location 2 days in advance. Today I can’t trust forecasts about whether it’s raining currently.

> To be fair, if something is on Mac, it is usually on Linux.

That's true only for CLI apps. My most frequently used GUI apps on Mac:

- MailMate

- Affinity Photo

- ACDSee Photo Studio

- NetNewsWire

- ApolloOne

- Textual

- Transmit

- iA Writer

None of them are available on Linux. Most of them are Mac-only (i.e. no Windows version either).

New comment by yakubin in "Why I always hit the crosswalk button (2015)"

Another instance of pedestrian congestion that’s really jarring to me are serial pedestrian crossings on roads with opposing traffic lanes separated by pavement, often on intersections. It may look like this: <https://maps.app.goo.gl/ErBFC2oXV21oQ9U7A>. For some reason, the traffic lights are programmed in such a way that most of the time you need to be almost running (I’d say something like 8-10 km/h) to ever have a chance of crossing both crossings in one go, even when you start walking at the beginning of the green light. Instead you’re almost always (the durations change throughout the day) guaranteed to stop before the second light and have fun breathing in the fumes from a high-traffic road. I can’t think of it as anything but hostile to pedestrians.

It was Go. Rust has many converts from C++. But from scripting languages too. It’s a pretty heterogenous programmer-base.

> A ton of coal will create much more co2 than ton of wood, isn't it?

Yes. But that hardly matters.

> For the same amount of energy the result should be similar amount of co2.

No. Apparently, wood is estimated to emit 30% more CO2 than coal for the same amount of energy[1].

> Coal is worse for people because burning it creates many unhealthy chemical components. Sulfur, heavy metals, etc

Is it more than when you burn wood though? I’m not knowleadgable enough to answer this question. I found one link about it[2], but currently I don’t have time to read it. In any case, the fact that it produces more CO2 than coal is a good argument against wood in my eyes. My argument is against wood, not in favour of coal. Coal is just a benchmark to measure against.

In this instance I’ll say burn it if you want. Although it leading to a natural wildfire is highly dependent on local climate. Where I live, for most of the year it’s too cold and humid for anything like this to happen, except during maybe 2 months a year. But I appreciate that in places like California or Australia it may be different.
