printf is superior and more concise, and snprintf is practically the only C string manipulation function that is not painful to use.

Try to print a 32-bit unsigned int as hexadecimal number of exactly 8 digits, using cout. You can do std::hex and std::setw(8) and std::setfill('0') and don’t forget to use std::dec afterwards, or you can just, you know, printf("%08x") like a sane person.

Just don’t forget to use -Werror=format but that is the default option on many compilers today.

C++23 now includes std::print which is exactly like printf but better, so the whole argument is over.

It’s way less expensive for state-sponsored hackers to blackmail your country’s official to leak backdoor keys than try to break the unbreakable crypto using a nuclear-powered GPU farm.

Synchronous translators are still very much in demand, as well as technical and legal translators.

Sometimes I’m searching for a recipe to some obscure Linux tool and finding my own answers on Stackoverflow from ten years ago.

As long as your byte consists of 8 bits.

Saving arbitrary metadata is the exact use case for pickle module, you just put it together with your numpy array into a tuple. jpeg format has support for storing metadata, but they are an afterthought like .mp3 tags, half of applications do not support them.

I can imagine multichannel jpeg to be used in photo editing software, so you can effortlessly create false-color plots of your infrared data, maybe even apply a beauty filter to your Eagle Nebula microwave scans.

What, pickle.dump your enormous Numpy array not good enough for you anymore? Not even fancy zlib.compress(pickle.dumps(enormousNumpyArray)) will satisfy you? Are you a scientist or a spectral data photographer?

Eh, who is still using paper books to learn programming languages? Every popular language has a website with online manuals.

Well, except C, because it’s crammed together with C++ on https://cplusplus.com/ and https://cppreference.com/

And socks just grow organically after 3 years of coding.

Being direct is good. But ‘too complex, refactor’ as an explanation is just one word longer than ‘fuck off’. You need to explain in detail why the solution is bad and which parts should be changed, in this case it just shows that the reviewer did not actually read the code.

1. Type letter ‘c’ using the text tool, as you’ve already done
2. Create a new layer from text
3. Duplicate layer
4. Transform - flip horizontally
5. Merge two layers

It’s a basic GIMP knowledge, really. Don’t forget to add an alpha channel to your layer after step 2, otherwise it won’t work.

We want to inhibit when running stuff like pacman, wget, cp or mv

There is already a separate systemd-inhibit command that does exactly what you need. Trust your users, they are capable of googling it (most of the time).

Only pacman and wget will benefit from suspend inhibition, because it will prevent breaking network connections. cp and mv will resume working just fine even when you hibernated your laptop while cp was executing. And in that case it’s less bug-prone to scan your system for active TCP connections to external addresses instead of adding a hack wakelock inside your terminal or inside wget.

It is also a poor idea to mess up with system-wide settings from some command when the user does not expect it, you’ll likely to get a thousand invalid bug reports that sleep mode is broken when some service randomly decides to use wget to continuously read from local Unix socket.

Yup. Now we have long-range WiFi filling that niche.

• They split off from Google.

• They are not using satellites, they shine a lazer from one fixed tower to another, with range about 20 km.

Should have used three spreadsheets. Excel tends to run slowly when a spreadsheet has more than a million cells in it.

There was no mention of over-the-air exploit, so eh.

Anyway, having direct unprivileged R/W access to platform memory is indeed a security hole, no matter the vendor.

It is not. ESP32 is an embedded chip with less than one megabyte of RAM. It cannot run apps or load websites with any malicious code, it only runs the firmware that you flash on it, nothing else, and of course your firmware has full access to every chip feature. If your firmware has a security hole, it’s not the chip’s fault.

Nope, the whole ${variable/regex/replacement} syntax

The most lumberjack-y tartans are Iowa (8% forests), Nevada (15% forests), Washington (52% forests), and Wisconsin (48% forests).

It’s a Python source with an executable flag set.

I guess plaintext garbage is big-endian.

I guess because ‘bin’ is a shorthand of ‘binary’, that is, the directory where all your executable files reside, so the developers felt a need to clarify that /usr/bin isn’t to be cleaned.
