Outside of the current function, yes. Anywhere, no.
Longjmp allows you to return to places you’ve already been and have saved with setjmp. Also attempting to longjmp to a function that has since returned is undefined behavior. Thus longjmp’s usual use case is like exceptions in other languages, going back up the call chain, skipping intermediate functions.

* `encoding` is what vim uses internally -- the way buffers and registers are stored in memory. Default value is latin1 as you mention, but it will also pick up on the $LANG environment variable. It's more effective in general to set that variable than directly tweak `encoding`. (Mine is en_US.UTF-8 due to my locale.)
* `fileencoding` is the encoding for the current buffer on disk, how it will be read and written. It is translated in memory to `encoding`. Thus you can manipulate files in encodings other than the one used in-memory. (Although if encoding was latin1 I'm not sure how well the round-trip would go.)
* `termencoding` is how the buffer will be displayed to the screen and how the user input will be read. Once again, it can differ from encoding, and will be translated.
* `fileencodings` is an ordered list of options to try when opening a file. Default value: "ucs-bom,utf-8,default,latin1" when encoding is a unicode value.
If you were editing Japanese text, for instance, choosing UTF-16 encoding would actually make vim use less memory than UTF-8, and would not affect the fileencoding used on disk either.

"Measuring" is exactly the wrong thing to do because often it is indicative of only your specific architecture/compiler.
> Unicode is pretty established, some use it with the wchar_t API in POSIX, some more as non-POSIX via external non-standardized utf-8 libraries
Just wanted to note that wchar_t is not POSIX per se, but comes from the C standard. It also suffers from various problems, see

> The examples in this article conform to the C89 standard, but we specify C99 in the Makefile because the ICU header files use C99-style (//) comments.
Serving public URIs for messages must be done by separate web servers like a webmail client, or a mail archiving tool such as Pipermail.
Oh god no, please don't turn email into a "surface."
> That means you’ll be able to do [x, y, z] right from the message, all without leaving your web-based email client.
Quit. Gmail.
Why are so many technical users still on this gross platform that is turning the earliest, most successful decentralized internet protocol into a walled surveillance advertiser garden?
If you use gmail, go register a domain and point your MX records at an honest mail provider like Fastmail, Posteo, or Kolabnow. Or run your own mail server. This way your mail provider is hidden behind your domain and you can change it in the future if desired.
Seriously, stop reading hacker news for a second and make today the day you start migrating away from Google.
> It's an archaic protocol built around the limitations of early-1980s systems.
What were the limitations, and how did they shape the protocol?
> protocol "feature" of having server responses be human-readable (and not machine-parseable)
The responses are successfully parsed by quite a few clients, no? The fact that I as a person can easily read the output would seem in and of itself to be a positive quality.
> control and data connections ... caused something like 2 decades of security problems, also makes it a nightmare to provision in modern networks
I know little about configuring network security, can you tell me more here? The idea is that in passive mode the server has to pick and listen on a bunch of random ports and so the firewall can't unconditionally block them?
Also you mention "modern networks" -- did it used to be easier to provision networks in the past and something has changed recently?
Thanks for reporting this. It looks ok for me in Safari 12.0.3, what version are you on?
The bulk of the work is done by Video.js 5.0.2. Perhaps your browser or plugins are blocking the script?
Can you send me an email with a screenshot? I do try to make the videos work on every browser if possible.
I also browsed a few of the FTP mirrors for OpenBSD and took note of how they formatted their response, and tried to make my format match what I observed to be the most common response. It's worked with all the clients I've tried so far: ncftp on mac, ftp on openbsd, Firefox, mac's ftp-finder integration, and Filezilla.
So while there is admittedly ambiguity in FTP servers on the whole, I think my server in particular should work OK. Keeping an open mind though if you know about a problem I haven't foreseen.
Writing in C requires care, but the modern day "rewrite it in rust" crusade does feel overblown. C programs are nice -- small and fast.
Anyway, I don't mean to be cocky. A code review is welcome, I'd be curious if I did indeed overlook a security issue.
Good point, and thanks for pointing it out. People can't read my mind and the example might give people the wrong idea. I'll add a note to the example.
Did you read the rest of that section? I have arguments about why ctype appears to be insufficient.
Can you give an example of the strncpy problem?
Also is there a precaution programs can take to use memset more safely?
OK, but "huge headache" is somewhat exaggerated. For many clients, gmail connection settings are a preset option, where you enter a username and application password. It's a one-time configuration.

My condolences.

You are perhaps an outlier? But I can see how it's a hassle in your particular case.
"From opening the heavy lid to placing your phone in the cradle, each analog movement becomes an intentional affirmation of the digital sacrifice you are about to make. To complete the gesture, close the box and encapsulate the device."
You can't just turn your phone off or get a dumb phone, you need a ritualized sarcophagus to bolster your decaying willpower.
I started using spaces for indentation just because I worked with people who did that. I kind of forgot I was even doing it because vim's auto-indent did a lot of the work, but after some time I realized spaces don't make sense.
The familiar arguments for tabs:
* Clean mapping between the concept of scope depth to a single character * Configurable display of indentation width, everyone can see what they want
Tabs have problems only when people use them for alignment, which breaks when tabwidth is changed.
Actually can someone try to change my mind? I know tabs-vs-spaces is an eternal war, yet I feel the problem is completely solved, hence I must be ignorant of the counter arguments.
(The only thing more logical than using tabs might be using no whitespace at all and having the editor determine presentation. But that wouldn't work well with line-oriented tools.)
The article is a good complement to one that I wrote about specifically the advantages - https://begriffs.com/posts/2018-06-05-mailing-list-vs-github...
Perhaps the answer is to consolidate business logic in the database with constraints. This also protects data from manipulation outside of an app, like with scripts or ETL.
Putting more logic in the db often results in terse error messages though, so the app needs to deal with that and make them nicer for the end user. I wrote about one possible approach here - https://begriffs.com/posts/2017-10-21-sql-domain-integrity.h...
> weak version control/deploy solutions
There are solutions that allow you to store migrations in version control, apply them to different database targets, and run consistency checks. For instance http://sqitch.org/ but maybe you're familiar with it already and regard it as one of the weak tools. Thought I'd point it out though.
> a new programming language to the stack
plpgsql is somewhat gnarly, but it is well adapted for the database. You know what it's going to do, compared with managing mappings from some other language. I never tried LINQ though so maybe the mapping would be more pleasant than I'm imagining.
I just put the RSS urls into a text file and the self-contained 1.7mb program does the rest. Somehow it gets by without using a combination of Electron, Mongo, Algolia, Redis, machine learning (!), and Sendgrid.
Maybe the comparison with a text-based RSS reader isn't fair and Winds does some crazy cool stuff, but it's hard to see what that is exactly.
Totally. I guess I should have mentioned that for me, at least, the books will be paired with hands-on hacking.
> The idea of reading 110+ books first in the hope you'll then start your epic hack sounds to me like epic procrastination.
Not planning to read book after book by the fire while the computer collects dust. :) For instance, I'm reading SQL books now and have done experiments that I then wrote about. Like transaction isolation levels, deferrable constraints, types/domains.
Lots of fun stuff to build. I find that the books help to give me a broader idea of the possibilities, that's all.
