Programming in a tree. I usually climb up here and read, but I decided to code, and I didn't drop my laptop :D

While working on my one of the first project in java i ended up using deprecated Calendar API for the date. Since deadline was near i thought it would be a good idea to use the JCalendar API for as date picker (which is a third party API).BAD IDEA. It was the night before the submission round about 11pm when i realized that there is no way to convert JCal object into Calendar and it turned out it is not working as expected you have to subtract a particular number from the year to get date right.
To convert JCal into Calendar i used the toString function to get the date in string sliced it using substring into year,month,day then had to assign date to Calendar object via constructor.
Had to write 70 lines of code just to convert JCal into Calendar...
And then there were other complications related to this problem. Had tu pull an all nighter just to solve date related problems
LESSONS LEARNED :
NEVER USE A DEPRECATED API
NEVER USE THIRD PARTY APIs WITHOUT RESEARCH

In PHP (yes, it's a language I... don't hate) I've always hated exceptions. They're like GOTO, in an OOP world with interfaces and contracts, try/catch is really odd as it breaks a promise about returning with a typed value.
But you can now do this in PHP8, which comes pretty close to Maybe/Either monads (Option, Result whatever it's called in other languages):
function getUser(): User | UserNotFound
PHP8 unions don't come with the same strong guarantees as in other languages but *pets PHP gently on the head* you did well, my boy.
Now I would really love it if PHP9 could do:
function getUsers(): Collection<User>
Type Tree<T> = Null | Node<T>;
function 🎄(): Tree<Branch<Ornament|Light|null>>15 -

Brilliant idea time:
Inspired by @TrojanMorse and his fractal trees
A fractal tree wallpaper that grows throughout the day.
So at 12 a script starts a new fractal and only uses depth 1 (a twig). Then every other hour it branches once more so at 2 am the fractal would have depth 2 and at noon it would have depth 7. That way you get a tree growing throughout the day for your screensaver. Now to make this a thing13 -
Buckle up, it's a long one.
Let me tell you why "Tree Shaking" is stupidity incarnate and why Rich Harris needs to stop talking about things he doesn't understand.
For reference, this is a direct response to the 2015 article here: https://medium.com/@Rich_Harris/...
"Tree shaking", as Rich puts it, is NOT dead code removal apparently, but instead only picking the parts that are actually used.
However, Rich has never heard of a C compiler, apparently. In C (or any systems language with basic optimizations), public (visible) members exposed to library consumers must have that code available to them, obviously. However, all of the other cruft that you don't actually use is removed - hence, dead code removal.
How does the compiler do that? Well, it does what Rich calls "tree shaking" by evaluating all of the pieces of code that are used by any codepaths used by any of the exported symbols, not just the "main module" (which doesn't exist in systems libraries).
It's the SAME FUCKING THING, he's just not researched enough to fully fucking understand that. But sure, tell me how the javascript community apparently invented something ELSE that you REALLY just repackaged and made more bloated/downright wrong (React Hooks, webpack, WebAssembly, etc.)
Speaking of Javascript, "tree shaking" is impossible to do with any degree of confidence, unlike statically typed/well defined languages. This is because you can create artificial references to values at runtime using string functions - which means, with the right input, almost anything can be run depending on the input.
How do you figure out what can and can't be? You can't! Since there is a runtime-based codepath and decision tree, you run into properties of Turing's halting problem, which cannot be solved completely.
With stricter languages such as C (which is where "dead code removal" is used quite aggressively), you can make very strong assertions at compile time about the usage of code. This is simply how C is still thousands of times faster than Javascript.
So no, Rich Harris, dead code removal is not "silly". Your entire premise about "live code inclusion" is technical jargon and buzzwordy drivel. Empty words at best.
This sort of shit is annoying and only feeds into this cycle of the web community not being Special enough and having to reinvent every single fucking facet of operating systems in your shitty bloated spyware-like browser and brand it with flashy Matrix-esque imagery and prose.
Fuck all of it.20 -

Redux is weird, and I don't like it because it violates the most basic principles of responsibility. The concept of expressing state changes as reducers is nice because it can be duplicated, saved and restored and compared for equality. So is creating isolated accessors and selectors. However, I really don't think a reducer should be aware of its own position in the hierarchy. When specifying an action you aren't addressing a reducer, you're addressing the tree. That the tree doesn't manage this addressing and expects reducers to identify themselves is a bit strange, especially considering that the whole point of having a tree is that reducers shouldn't be affected by their position in that tree because they're pure. Same goes for selectors, they should belong to the tree, not to any particular sub-reducer. Separating the slices is reasonable structure, but if you specify parts of the addressing in the slice and parts of it in the root you might as well just use separate reducers for each of your slices. It's functionally equivalent.12

So my data structure's exam's result came and i got scored 57.5 out of 80. My classmates who barely know anything about C scored way more than me. I am so embarrassed at myself but i gave the right answers in exam. My score in the exams before was 39/40 and 38.5/40. All my hardwork failed because it was a so called THEORY exam where there was only 2 small questions of writing algos but all others were just like "describe pre-order traversal of a binary tree" or "write the difference between a tree and a graph?define adjacent node, path and complete graph"...

NPM and the whole dependency tree for JS packages should burn in the pits of hell.
Let's pretend that uninstalling a single (albeit larger) module didn't take 8 minutes and that it didn't spit out 20 warnings from a total of 277 (HOLY FUCK) related packages.
How can you guys (JS-only devs) handle this ?!15 -
I just got mindustry (which is currently on sale for $3) and it's a great tower defence, resource production, machine builder, tech tree researcher, sort of game! Really really worth the $3 and will probably appeal to a lot of people here.7

*One Month Ago*
Project Manager: we have allocated these two workstations for you to extract data (set) from malicious files, they are off the network. I though would also prefer a seperate laptop for this project you can take this one (pointing towards the newish laptop on the table)
Me: (i declined his offer because i didn't wanted to carry two laptops everywhere) I'm going to use my own laptop, but I'll be using a sand box or virtual machine.
*Fast Forward to Today*
Accidentally ran a script outside the sandbox, which due to some unknown reasons ended up executing a bunch of malicious files I only realised my mistake when my antivirus started to go bonkers FML.
P.S. both of those PCs are now connected network because of me.

So I thought I knew source tree, apparently I do not... Lost a week's worth of work, went to history, saw someone removed it with a commit, and now I'm getting blamed for my own work 'disappearing'. The reason I am being told I am to blame is how I control my branches... So how I do it is that I keep a local copy of the master branch, I keep it updated and monitor it for changes regularly (meaning fetch and pull cause double tap..) before I do a merge, I check for any new code on master again, then using the local copy of master, which I just updated, I pull the master changes into my branch, deal with any conflicts, build and done. Then I request my changes into master once I am happy everything is good.
My question is, clearly there is something wrong with the way I do things, so please source tree users, what is the most fool proof way to pull latest from master so that I don't loose code? 😔11 -

So I see posts about an interview question/challenge of inverting a binary tree. I don't use trees very often (mainly file related or parsing server nodes), but I thought I would learn how to do this.
I saw a page that started talking about different ways to invert enough to understand that one type of inversion is swapping left and right nodes. So I stopped before they showed how.
Then I created a test program that has a tree structure and also can display a tree before and after modification. This was kind of fun.
So then I wrote the inversion function. It was less than 10 lines of code. Wtf? I thought it would be harder than this.
Then I started wondering where trees were used. So today I have been learning how they are used and why I might need one to solve a problem. One use I intuited was parsing regex or a language. Apparently it is useful there.
What I am learning is that a lot of these interview questions are really test to see if you can comprehend instructions when stressed. Or you will ask questions to clarify the task. It doesn't necessarily test your ability to solve hard problems.
One thing that perplexes me. If inverting a tree is swapping nodes left<->right, then why not leave data in place and just swap roles in the functions. Maybe I completely misunderstood what inversion means or why it would be done. I guess if this is not inverting I have the structure to try other methods now.2 -
I recently went through a very detailed and well-explained Python-based project/lesson by Karpathy which is called micrograd. This is a tiny scalar-valued autograd engine and a neural net on top of it.
The project above is, as expected, built on Python. For learning purposes, I wanted to see how such a network may be implemented in TypeScript and came up with a 🤖 micrograd-ts - https://github.com/trekhleb/... repository (and also with a demo - https://trekhleb.dev/micrograd-ts/ of how the network may be trained).
Trying to build anything on your own very often gives you a much better understanding of a topic. So, this was a good exercise, especially taking into account that the whole code is just ~200 lines of TS code with no external dependencies.
The micrograd-ts repository might be useful for those who want to get a basic understanding of how neural networks work, using a TypeScript environment for experimentation.
With that being said, let me give you some more information about the project.
## Project structure
- [micrograd/](https://github.com/trekhleb/...) — this folder is the core/purpose of the repo
- [engine.ts](https://github.com/trekhleb/...) — the scalar `Value` class that supports basic math operations like `add`, `sub`, `div`, `mul`, `pow`, `exp`, `tanh` and has a `backward()` method that calculates a derivative of the expression, which is required for back-propagation flow.
- [nn.ts](https://github.com/trekhleb/...) — the `Neuron`, `Layer`, and `MLP` (multi-layer perceptron) classes that implement a neural network on top of the differentiable scalar `Values`.
- [demo/](https://github.com/trekhleb/...) - demo React application to experiment with the micrograd code
- [src/demos/](https://github.com/trekhleb/...) - several playgrounds where you can experiment with the `Neuron`, `Layer`, and `MLP` classes.
Demo (online)

The factorization shit I'm always ranting about? I decided for once to explain it visually in this handy dandy little infographic.
We're essentially transforming the product from an unsmooth set of potential factors in its factor tree, to a factorization tree that guarantees first that the set of potential factors are all 2, 3, 5, and a or b of p, and second, that all the factors are *smooth integers* of a or b.
This is basically what Adi Shamir was trying to do with TWINKLE and TWIRL, despite checking a hundred thousand+ potential primes.
I did it in four.7 -

Can JS events bubble in trees of objects other than DOM nodes? If so, what properties do I need?
I tried to read this: https://dom.spec.whatwg.org//... but it's stupid long, references a bunch of other functions and I got lost in between the variables.
I'm kinda confused because it often uses type checks (i.e. if target is a Node or a Window object), which goes against the very point of duck typing.
I could technically make my nodes into DOM nodes, but I'd rather have them inherit from Worker.1 -

Hi everyone! I'm in need of some help regarding the approach to my bachelor thesis.
The practical stuff is basically clickstream/task and usability analysis on an existing platform and creating mockup improvements for some processes. I was thinking about using a spider to generate a tree (or another datastructure) regarding all the different tasks available and then trying to optimise said tree, thus automatically optimising the processes within. I'm having however issues imagining how this optimisation might be generalised for more than this one platform.
Basically, I'm a bit lost and grasping for any pointers in any direction regarding these ideas.3 -

PHP is like the black sheep on every family tree. Lots of work revolves around him. It's prone to failure, break up easily, does things in an inefficient manner, and gets all kind of disease. So I'm using other family memebers, C++ and Go, to keep him on track.8

I hate to say it, but planting trees won’t help us remove carbon from the atmosphere. Every single last bit of carbon dioxide that the tree consumed will be put back into the atmosphere when the tree dies and decomposes. Artificial tree plantations are not forests. They have no animals, no birds, nothing. Trees don’t live long there.
Team Trees might be a good awareness project, but it has a layer of toxic positivity to it. It most definitely serves as an emotional band-aid at best, and deters people from working on real solutions at worst. Large things like climate are never that easy.5
