*The interview wasn't off to a good start, as the recruiter forgot he invited me for an interview, so he just led me to some empty office after letting me wait for good 15 minutes. *
Them: Here, write some pseudocode to find a value in a tree.
Me (thinking): Interesting question; DFS / BFS would be really simple here, but nobody uses trees for that - perhaps I should ask about characteristics of the tree in question?
But before I realised, the interviewer already rushed out the office, so I just picked up my jacket and left... -
I've seen a job vacancy that asks for the following characteristics in a developer:
- extraverted, do'er (as opposed to thinker), out-of-the-box, curious, sees solutions and not problems, structural thinking vs. theoretical thinking, loves change, acts immediately, makes choices under stress, critically questions themselves if things go wrong
What the [censored] kind of programmer is that? Sounds more like a wannabe brogrammer type.
A typical, real programmer is introverted (for he is introspective, detail-minded and is therefore good at inspecting problems and finding solutions for them).
Seeing problems is not a bad thing, it's in fact necessary to be able to identify issues and not act like your typical manager who only wants to rush to solutions. He thinks deeply and theoretically before he takes action. Theory is the foundation of identifying a problem.
What programmer is stress-resistant? It's not normal for the human brain to be able to deal with stress; this is why switch-tasking is so hard.
Question yourself if things go wrong? Perhaps, but this sounds more like trying to shove the blame around.
Since we live in a rigid computer world with rigidly-defined protocols (say, HTTP), it is often useful to think in a conventional way. Out-of-the-box? Sure, if you're being innovative, or sure, as a tangential characteristic.
In my professional opinion, this vacancy reeks of bad corporate culture.. and the biggest alarm bell I find is: "There is free beer!" Err.. yeah. Anyway.8 -

PHP arrays.
The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.
What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.
This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.
You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.
Bonus PHP trivia:
Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.
`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.
Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.
Strings can be indexed with negative integers. Arrays can't.
ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.
`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.5 -
My arguments about Apple:
- "iPhone 12 camera can be better than anything else because it's more advanced, it has LiDAR and 10-bit codecs"
- "I can copy on my iPhone and paste on my MacBook and vice versa out of the box"
- "My Beats can seamlessly switch from playing from my MacBook to my iPhone to my Apple Watch. I can be exercising with only my Apple Watch and my Beats, no need for iPhone"
- "2K screen with nice colors in a 900g laptop is rare if you consider the price. Apple one is the cheapest one with that characteristics"
- "Apple Pay is convenient"
- "Fingerprint scanners fail with wet fingers no matter if it's ultrasonic or optical, LiDAR Face ID is objectively more secure than any camera-based unlock mechanism"
- "Stainless steel frame feels better than aluminum one"
I'm not saying Apple is the best. I'm not saying that Google Pay doesn't exist or that Apple Pay is better. I'm not saying that Apple has no downsides.
However, these are responses I get:
"But Apple IS crapple, immutably"
"Why are you even looking at apple crap if you want something good"
If you want to bash Apple, bash it for something real like that butterfly keyboard fails, unconventional AirPods shape that makes most people's ears hurt, screen coating fails on MacBooks, App Store commissions.47 -
Hello everyone,
I'm new here. [OK. Let's skip this]
I want to know where to begin on my journey on learning how to create a program that predicts what a user will say next by storing already said things and by making specific characteristics for the users.
I know that I will need to train it with some data first lol.
But how will it do the prediction. I just need this part of understanding.
I'm sorry for my bad English btw.7 -

I see a lot of crap about junior vs senior devs nowadays. I think the distinctions are small.
In reality senior devs have been burnt more in the past by their own mistakes or have seen mistakes by other people. That's about it.
What other distinguishing characteristics have you found?7 -
In the land of Kangaroos you can claim education expenses directly related to your profession on your tax return. I am developing a plug-in for X-Plane. Do you guys think I can claim costs of my flying school as "education to better understand flight characteristics so that my plug-in works better"?
For anyone who's interested, I'm building a six pack using round LCD displays and an Arduino

I hoped I would write about other things than EU internet regulation... But I hoped wrong.
The new online antiterror regulation is flawed, too.
What will the new regulation change?
The EU plans stricter anti terror laws for online platforms. In a nutshell, reported terroristic content has to be removed in <1 hour> after reporting. While automated filters are not required (the EVP party and the EU commission wanted those, but couldn't get a majority in the perliament), but it is unclear how to fulfill the regulation without.
What is the current progress of the regulation?
The EU parliament approved the draft, the trialogue will begin after election. The parliament has to approve the final trialogue result again and might reject it then. The characteristics of the regulation might change, too.
Who (platforms) will be affected?
All platforms, "offering servicd in the EU, independent of their business address" (free translation from German).
Will there be exceptions (e.g. for smaller or non commercial platforms)?
No.
At the very first report, the platform will have 12h time.
What are the consequences of not following?
Regularly breaking the law _constantly_, up to 4%/of the total yearly revenue.

- The law proposal itself (also outdated): https://eur-lex.europa.eu/legal-con...

For whatever ungodly reason my containers library, which has extensive testing, profiling, and benchmarks against other containers libraries receives regular emails directed towards me about it, always one of two things
1) "don't reinvent the wheel" I have to assume these people haven't looked at the performance characteristics or features at all. I didn't waste away weeks of my life. I needed something and couldn't find it anywhere. I'm outperforming many crap implementations by nearly an order of magnitude, and can offer queries upon the containers in both generalized and specialized forms. As an analogy, I made airless 3d printed wheels, and people are regularly telling me I should still be using ancient wooden spoke wheels; they probably would argue in favor of using a horse drawn carriage as well. How is it possible technically minded people can also be so anti-progress?
2) "Please rewrite this in X language." You know what? YOU rewrite it. I chose what I did because it made it easy to do what I needed to do. Hilariously, the languages I get asked to use most often, are the same who's containers libraries perform worst in the benchmarks.
Both sound like half baked developers trying to sound superior. Pull your head out of your ass and actually outperform me and others. I'm so fucking sick of this "all talk no action" bullshit.5 -
I don't profess to know the whole story, but what is it with the (what seems to me to be) overly-fragile, cry-bully mentality of the Node.js community and its various branches? The current mess is not the first time strongly opinioned, overly zealous loud-mouths have driven the ship.
Throughout the history of time, teams/groups of people have been made up of different characters. Some are nice, some aren't really and everyone has varied characteristics. There seems to be a drive to completely flatten the behaviour, beliefs and attitudes of any sort of gathering, and it makes me so mad. Some people are so obsessed with their ideas of equality, diversity, inclusivity and safe spaces that they can't see how negative and discriminating those attitudes actually are.
I fully accept that certain behaviours should not be tolerated and should be called out. And communities and societies will organically decide what those are.
But when you raise an issue, approach it like grown up and thrash it out to a resolution - don't throw your toys out of the pram and put on a real public show, targeting and scapegoating other individuals when you don't get your way! This is childish and narcissistic. If this is your only course of action, you should realise you haven't a strong argument.
I've ranted here before about how the mainly social media discussions on any subject drive us all to extreme ends. And this is just another example. It's wrong and narrow minded and not remotely progressive - the opposite of what those who should loudest claim to be.3 -
"Desired Characteristics:
Solid software development skills, in at least one major language (e.g. Java, JS, Node.JS, C, C++)"
Node, huh...2 -
Today I want to put an age-old question to rest. What is art and what is not? What's the difference? In art world, there is actually a consensus that was reached in the second half of 20th century.
First, the audience has no merit to decide what's art and what's not, as art has inherent characteristics. So whether a piece is art or not is left for the artist to decide.
But the artist too cannot just call anything they make art. There is just one criterion — if only the art piece itself is enough to justify its making, and the artist sees it as the only award they need for making it, it's art. Otherwise, it's not.
"But wait, that's not entirely correct, this is incomplete", you say. Well, it's in fact complete, but because our society progressed way faster than our languages, we're having a hard time to describe novel complex things with words. Language can't keep up with rising complexity.
We use "horseless carriages" instead of "cars" when we describe anything complex enough. The good explanation of how language works and why do we act like this is outlined beautifully in Benjamin Bratton's "The New Normal". A small book of forty-something pages, but I never spent that much time on every page in my life. The best book investment for me after "The Code Complete".22 -
Today on my science test they asked, "There is an animal in a cage, how would you find out if it is a bird or a mammal?"
a. compare it to the characteristics of birds and mammals
b. see if it has a beak
c. look at it's droppings
d. open the cage and see if it flies out
Out of all the questions, d is the most reliable.6 -
What do you think about psychometric tests? I doubt a test can define the type of person you are nor your characteristics. I think it's ambigous, unprecise and extremely subjective. Today I was rejected from a job offer because "the psychometric department didn't give their vote of approval". This is the first time I get rejected for that reason, in the past nobody complained about the results of my tests. I don't know if psychometry is useful, but this company is looking for someone different, or maybe psychometry is, in fact, subjective and any fool can interpret your results however he feels like: "Oh, so he likes kittens over puppies, he's a potential serial killer, let's reject him"1

I feel so exxasperated listening to the same people talk about the same shit, most especially when they're perpetuating the same stupidity I feel like correcting.
Like saying that mythological depictions of animals were often based off stereotypical percepts of what the host culture tended to believe the nature of an animal was or what its most defining characteristics were. Like for example, Rams can tend to be a tad territorial and charge people in their enclosures. Maybe they won't act like that towards their owner but they may to a stranger. Or sheep which are of the same species, just females, are represented as being docile since they live their lives being herded and sheared or sometimes slaughtered for food. Primary culturally oriented perceptions of animals. But these people say the same shit over and over and over.10 -
What ai model would I use to propagate a series of survival factors and decision making scenarios that if the optimal order of activities are pursued would lead survival and even prosperity and the worst set of possibilities would lead to death where the environment and sensations being experienced would always lead to specific pitfalls but wherein some of these pathways would lead to later reward and where the obstacles like predators could be overcome by simple combinations of objects which would be a crude mimicry of the invention ?
Neural nets don’t see to fit this given my understanding but there is a training aspect I’m looking for where the creature being simulated dies, develops fear responses, feels pain, avoids pain, remembers things, develops behaviors related to characteristics in creatures, has unborn motivations that weight decisions, and learns to prioritize.
I had created a massive dataset of objects including memories and aspects of semantic memory and episodic memory colored by emotion inspired by past conflict and reward with the idea that a running average would affect behavior and decide on various behaviors all the way down to perceptual differences
Any thoughts again ? Or will wolf try to steal these too ?29 -
Who do you think is the coolest super hero?
Putting aside technical topics and thinking about hobbies and cinematography, who do you think could be the most popular superhero? I had this dispute with classmates because I collect all the information about Spiderman. I described the biographies of the actors of the films, using various data on the network like https://writingbros.com/essay-examp... I collected information about the character characteristics and reviews on movies. I wanted to write my essay about Spiderman, but none of my classmates supported me. According to the general opinion, he cannot be popular and attract attention.
Maybe he doesn't have the traits of the Hulk or the Powers of the X-Men. But, a super hero is an ordinary person who goes to an ordinary job and leads a seemingly ordinary life.
I thought it was characteristics like these that should attract people.
Who do you think might be one of the most popular superheroes of our time. Of course, it is impossible to single out one leader. But maybe you can form the top 3.

for everything to move on people have to shed their greed but you people also have to shed the pointlessly destructive characteristics which are inherent to your core natures. the idiotic thing you people fought to infect the world with most especially.
life wasnt easy but it wasnt this hard.
someone told me that you people think this stupid color number idiot slave bullshit is cleaved to because its believed that is the only way to have anything in this life.
what did you people really do to earn any of the few things you got ? and there the ability to do these things, travel which is harmless, stay in nice hotels which is harmless, see things, which is harmless, have time to visit museums and the like which is harmless, without your lives being ruined.. which is happening because you all allow this.
a cycle completes its period. something is lost, mostly energy youth and time.
why not simply give the people a promise of some time and some better reward and cap things like inflation and do away with all the stupid shit that originally just derived from bored rich people throwing you all some table scraps in exchange for degrading yourselves and destroying future generations ?1 -
I've been sitting here staring at extension types and I wonder, what if I had a partial file with partial data ?
In general one could say that in every case where say a header is missing that is ALWAYS going to have some identifying characteristics even given a characteristic statistically frequent pattern of data, that there is always a null value that appears as total chaos.
But I wonder, is there a way beyond simply trying every goddamn possible combination of things until meaningful data is extracted to identify a file by its content when part of that content that is usually used for such a purpose, is missing ?
What kind of application or technology would be required for this ? Certainly not neural networks, but obviously some kind of ai right ?10 -
