Run from bash like your career depends on it

Bash is the worst pile of anti-patterns and hacked up bullshit, but what would you expect from something that’s been our emergency-room band-aid for as long as we’ve been alive? This is just a reminder, for your career’s sake, to NOT make it one of your “specialty languages”. Learn what you have to. And double down on a modern, sane scripting language. I’ve tooled up node to do all things command-line, I recommend you do the same – but even writing little Java or C++ command-line apps is better than letting bash poison your brain! Just say no. And some day, our great-great-grandchildren will have a replacement. No, not another sh variant. A true sane modern programming language. okbyeeee!

Hate of the day: I love how [rm -f ] “fails” (non-zero error code) but [mkdir -p …] “succeeds”, and there is no [mv -f …]. The Unix philosophy: do one thing, and do it well, but always slightly differently than anyone else would have done it. Sure it’s bizarre bazaar chaos, but it’s “beautiful”. Ummmm…. no, fuck you, I don’t want to memorize your chaos.

UPDATE: Dude. In my defense I was in pain and jacked on meds when I wrote this, haha. Step away from the oxy, take less Adderall… calm ye self down. “Whatever Works”.

UPDATE 2: Yeah, the horror is real. Yet another damning example of why, for your career’s sake, you should focus on a real scripting language and not (ba)sh’s arbitrary stupidity.

C++11 thread_local set us up the bomb

The thread_local scope tells the compiler to create one unique version of a variable per thread. Then you can access it without worrying at all about in what thread you are. (Grammar Nazis, help me out here. I think I got that right…) It is absolutely genius for making multi threaded programming that much easier. W00t.

UPDATE: of course, every razor blade comes with its share of nicks. In this case, the expectation that different objects in the same thread would still have different thread_local members. Nope! Vet your ideas before you change to this scope too fast! Me, I’m all better now, and still love it. Good luck girls and boys.

Postgres JSONB field type conversion

Example to convert a field from real type to integer type:

update bracketevents set json = jsonb_set(json, '{sq_id}', ((round(cast(json->>'sq_id' as real))::text)::jsonb));

All that just remove the $*(@ decimals… how particular…

Getting pretty Google fonts into WordPress

This article is a great explanation of the details. To explain.. no, too much. To sum up:

Go to Google Fonts and browse around and select ones you like, then click the bar in the footer to get an installation guide. This generated link is the important part:
- https://fonts.googleapis.com/css?family=Lato|Montserrat|Oswald|Quicksand|Roboto
- Because it is a “heavy thing”, I pared that list down to Montserrat for paragraph text and Quicksand for headings.
Put one-shot loading of the link into functions.php (details on wiki); example:

function custom_add_google_fonts() {  
    wp_enqueue_style( 
        'custom-google-fonts', 
        'https://fonts.googleapis.com/css?family=Montserrat|Quicksand',
        false 
    );  
}  
add_action( 'wp_enqueue_scripts', 'custom_add_google_fonts' );

Specify the style in CSS (details on wiki):

body {  font-family: Montserrat, sans-serif;  font-weight: normal;  }
#content h2 {  font-family: Quicksand, sans-serif;  font-weight: bold;  }
