Any tips on how to properly document my code? I'm going to start my first internship soon so I need to learn it.11

It makes sense to learn AI and its mathematical basis (statistics and linear algebra) or unless I want to get a degree on the topic I’m wasting my time? If the answer is yes what are the best online resources/books which I can use?
To clarify I don’t want to specialize there and work as a “AI/data science specialist” (for which I believe a degree it’s necessary) as some graduates in shady boot camps expects to do. I’m just asking myself if I can teach myself enough IA to enrich personal projects in which IA makes sense and to become apre flexible professional.5 -
Dogecoin hit USD $0.40 recently, which means it's time for the Crypto Rant.
TL;DR: Dogecoin is shit and is logically guaranteed to eventually fall unless it is fundamentally changed.
===========================
If you know how Crypto works under the hood, you can skip to the next section. If you don't, here's the general xyz-coin formula:
Money is sent via transactions, which are validated by *anybody*.
Since transactions are validated by anybody, the system needs to make sure you're not fucking it up on purpose.
The current idea (that most coins use today) is called proof-of-work. In short, you're given an extremely difficult task, and the general idea is you wouldn't be willing to do that work if you were just going to fuck up the system.
For validating these transactions, you are rewarded twofold:
1) You are given a fixed-size prize of the currency from the system itself. This is how new currency is introduced, or "minted" if you prefer.
2) You are given variable-size and user-determined prize called "transaction fees", but it could be more accurately called a "bribe" since it's sole purpose is to entice miners to add YOUR transaction to their block.
This system of validation and reward is called mining.
===========================
This smaller section compares the design o f BTC to Dogecoin - which will lead to my final argument
In BTC, the time between blocks (chunks of data which record transactions and are added to the chain, hence blockchain) is ten minutes. Every ten minutes, BTC transactions are validated and new Bitcoins are born.
In Dogecoin, the time between blocks is only one minute. In Theory, this means that mining Dogecoin is about ten times easier, because the system expects you to be able to solve the proof of work in an average of one minute.
The huge difference between BTC and Doge is the block reward (Fixed amount; new coins minted). The block reward for BTC is somewhat complicated compared to Doge: It started as 50 BTC per block and every 4 years it is halved ("the great halving"). Right now it's 6.25 BTC per block. Soon, the block reward will be almost nothing until BTC hits it's max of 21 million bitcoins "minted".
Dogecoin reward is 10,000 coins per block. And it will be that way for the end of time - no maximum, no great halving. And remember, for every 1 BTC block mined, 10 Doge blocks are mined.
===========================
Bitcoin and Dogecoin are now the two most popular coins in pop culture. What makes me angry is the widespread misunderstanding of the differences between the two. It is likely that most investors buy Dogecoin thinking they're getting in "early" because it's so cheap. They think it's cheap because it isn't as popular as Bitcoin yet. They're wrong. It's cheap because of what's outlined in section two of this rant.
Dogecoin is actually not very far off Bitcoin. Do the math: there's a bit over 100 billion Dogecoin in circulation (130b). There's about 20 million BTC. Calculate their total CURRENT values:
130b * $0.40 = 52b
20m * $60k = 1.2t
...and Doge is rising much, much faster than BTC because of the aforementioned lack of understanding.
The most common thing I hear about Doge is that "nobody expects it to reach Bitcoin levels" (referring to being worth 60k a fucking coin). They don't realize that if Doge gets to be worth just $10 a coin, it will not just reach Bitcoin levels but overtake Bitcoin in value ($1.3T).
===========================
It's worth highlighting that Dogecoin is literally designed to fail. Since it lacks a cap on new coins being introduced, it's just simple math that no matter how much Doge rises, it will eventually be worthless. And it won't take centuries, remember that 100k new Doge are mined EVERY TEN MINUTES. 1,440 minutes in a day * 10K per minute is 14.4 million new coins per day. That's damn near every Bitcoin to ever exist mined every day in Dogecoin10 -
Great alternative to google translate if your languages are supported: https://www.deepl.com/translator has much more fluent translations too.10

I just invented a new JavaScript operator. It's named "plus with wings", and it's used to sum to numbers without ambiguity or any need of type conversion, for example:
3 -+- "2" // 5
"2.1" -+- "4" // 6.1
"-1.1" -+- "" // -1.1
So, from now, you won't have to wonder anymore what type is that variable.

MOTHER OF ALL AUTOMATIONS
This seems a long post. but you will definitely +1 the post after reading this.
xxx: OK, so, our build engineer has left for another company. The dude was literally living inside the terminal. You know, that type of a guy who loves Vim, creates diagrams in Dot and writes wiki-posts in Markdown... If something - anything - requires more than 90 seconds of his time, he writes a script to automate that.
xxx: So we're sitting here, looking through his, uhm, "legacy"
xxx: You're gonna love this
xxx: smack-my-bitch-up.sh - sends a text message "late at work" to his wife (apparently). Automatically picks reasons from an array of strings, randomly. Runs inside a cron-job. The job fires if there are active SSH-sessions on the server after 9pm with his login.
xxx: kumar-asshole.sh - scans the inbox for emails from "Kumar" (a DBA at our clients). Looks for keywords like "help", "trouble", "sorry" etc. If keywords are found - the script SSHes into the clients server and rolls back the staging database to the latest backup. Then sends a reply "no worries mate, be careful next time".
xxx: hangover.sh - another cron-job that is set to specific dates. Sends automated emails like "not feeling well/gonna work from home" etc. Adds a random "reason" from another predefined array of strings. Fires if there are no interactive sessions on the server at 8:45am.
xxx: (and the oscar goes to) fuckingcoffee.sh - this one waits exactly 17 seconds (!), then opens an SSH session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has SSHD up and running) and sends some weird gibberish to it. Looks binary. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.
xxx: holy sh*t I'm keeping those

For all those that saw my previous post about Facebook embedding tracking metadata into photos: I just released a website for my project that allows you to obfuscate the tracking data in your browser.

This is more just a note for younger and less experienced devs out there...
I've been doing this for around 25 years professionally, and about 15 years more generally beyond that. I've seen a lot and done a lot, many things most developers never will: built my own OS (nothing especially amazing, but still), created my own language and compiler for it, created multiple web frameworks and UI toolkits from scratch before those things were common like they are today. I've had eleven technical books published, along with some articles. I've done interviews and speaking engagements at various user groups, meetups and conferences. I've taught classes on programming. On the job, I'm the guy that others often come to when they have a difficult problem they are having trouble solving because I seem to them to usually have the answer, or at least a gut feel that gets them on the right track. To be blunt, I've probably forgotten more about CS than a lot of devs will ever know and it's all just a natural consequence of doing this for so long.
I don't say any of this to try and impress anyone, I really don't... I say it only so that there's some weight behind what I say next:
Almost every day I feel like I'm not good enough. Sometimes, I face a challenge that feels like it might be the one that finally breaks me. I often feel like I don't have a clue what to do next. My head bangs against the wall as much as anyone and I do my fair share of yelling and screaming out of frustration. I beat myself up for every little mistake, and I make plenty.
Imposter syndrome is very real and it never truly goes away no matter what successes you've had and you have to fight the urge to feel shame when things aren't going well because you're not alone in those feelings and they can destroy even the best of us. I suppose the Torvald's and Carmack's of the world possibly don't experience it, but us mere mortals do and we probably always will - at least, I'm still waiting for it to go away!
Remember that what we do is intrinsically hard. What we do is something not everyone can do, contrary to all the "anyone can code" things people do. In some ways, it's unnatural even! Therefore, we shouldn't expect to not face tough days, and being human, the stress of those days gets to us all and causes us to doubt ourselves in a very insidious way.
But, it's okay. You're not alone. Hang in there and go easy on yourself! You'll only ever truly fail if you give up.32 -
I've been wanting to get into circuit design and general electronics for a while now. PCBs seem interesting.
What can you people recommend me to start learning it? I've only found some random courses by people with thick accent I cant understand.5
