Programming in a tree. I usually climb up here and read, but I decided to code, and I didn't drop my laptop :D
I covered the screen with my hand because my code's ugly, and I don't want anyone to see it lol.

Hey folks, I've just launched the https://okso.app - it is a drawing app that you may use to express, grasp, and organize your thoughts and ideas.
One key feature there is that you may organize your drawings/sketches into a hierarchical tree structure so that a large amount of data would be more manageable and less overwhelming.
I hope you find this app useful!

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>;

When I was about 13, I opened up command prompt on Windows, and changed the color of it to green then ran the tree command. So, not thinking of anything, this was in the library in front of about 60 people and 2 teachers.
All others saw was green text going down fast, and instantly presumed that I was hacking since they knew I was into coding and finding exploits, and just knew how to use a computer better than them in simple terms (HACKER MAN). Thus this lead to me getting sent to the principal's office... I almost got suspended cause I ran the tree command in green.
Two questions for me remain unanswered, that I would love to know. What would've happened if command prompt was printing text in red. Another question becomes, what would've happened if people saw me pinging Google or some popular site.4 -

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 -
Could do with some dev input here.
Going to rename most of my projects before I start them up again just for some consistency amongst everything so...

Main thing first: I got lucky, CTs and X-rays showed no lasting damage. I'm back home and safe now.
What got me was going through the hospital having to hear the story of how I fell out of a tree onto my back and head like an idiot... from medical person to medical person.
I was lying in the bed, thinking "I swear I'm competent!? Why do people trust me!?"

The saddest and funniest side of our industry is (atleast in India): someone works hard and makes it to the best colleges, do great projects on AI, ML; get a good score on Leetcode, codechef; gets a job in FAANG-like companies...
Changes colors in CSS and texts in HTML.
And, why is there so much emphasis on Data Structures and Algorithms? I mean, a little bit is fine, but why get obsessed with it when you never write algorithms in production code?
Now, don't tell me that, we use libraries and we should know what we are doing, no, we don't use algorithms even in libraries.
Now, before you tell me that MySQL uses B-tree for maintaining indexes, you really don't need to solve tricky questions to be able to understand how a B-tree works.
It's just absurd.
I know how to little bit on how design scalable systems.
I know how to write good code that is both modular and extensible.
I know how to mentor interns and turn them into employees.
I know how to mentor junior engineers (freshers) and help them get started.
Heck I can even invert a binary tree.
But some FAANG company would reject me because I cannot solve a very tricky dynamic programming question.4 -

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"...

Merry Grav-Mass!
So I saw many „Merry Christmas“ posts here lately.
But many of you may have forgotten that 25th of December is the birthday of the greatest physician and mathematician of all time — Isaac Newton! So let's celebrate the existence of comprehensible physical laws!
One way to celebrate Grav-Mass is to decorate a tree with apples and other fruits. Glue them or attach them, but not too well! The idea is that occasionally a fruit should fall. Put them on the tree no more than 2 feet up, so that they won't get damaged or hurt anybody when they fall. Investigating and perfecting the methods for doing this is a great way expose a child to the process of scientifically studying the behavior of the physical world.
Merry Grav-Mass and happy New Year! 🍎

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.

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 -

Consider an API that uses the HTTP path to represent position in a tree that literally represents a file tree with minimal constraints, and GET/PUT/DELETE methods to read, write and destroy the nodes. How would you encode read/write operations to per-node metadata? The kinds of metadata are static and around 4, so inventing HTTP verbs for each of them is infeasible but filtering is not necessary.
Options considered so far:
- toplevel resources alongside a namespaced /data such as /acl, /lock
- magic keywords to the Range header (this is apparently compliant)
- mimetypes such as text/plain+acl
- SETPROP / PROP methods in the spirit of WebDAV
- headers (I worry this may become an immitigable bottleneck really fast)
I'm looking for any kind of suggestion or insight, not perfect answers.
I read the WebDAV specification and I won't even suggest that I'm trying to align with it, the only protocol I'd seen in the past with comparable scope bloat is WebRTC.22 -

How do case insensitive searches work?
Usually if I needed case insensitivity, I'd probably just store all the keys in lowercase and for searches convert whatever is typed to lowercase.
But what about Google. Can't convert everything to lower.
And if need to check the lower and upper case of each letter, like in a Tree, you would need to go down 2^N paths?20 -

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 -

I know it a strange thing to ask but I need help with English grammar ( I am not a English native)
I am doing an assignment on context free grammar program.
What the program need to do it "Produce a grammar tree based on the rule"
For example a sentence "Jame sat.", It will need to produce a grammar tree like this.
S
_____|___
NP VP
| |
N V
| |
holmes sat
The only thing I need to do it give a grammar rule to the program like this
S -> NP VP
NP -> N | Det N
VP -> V | NP
What the above rule said is that the sentence is composed of Noun Phrase and Verb Phrase and Noun Phrase is either is a Noun or a determiner and Noun.
Now here is the meat of the question.
I am having trouble parsing a grammar tree for this sentence "She never said a word until we were at the door here"
I have provided my grammar rule below. I think I forget to add some grammar rule or some of my grammar rule are incorrect. I am not a native English speaker so I am having trouble on it.
The search engine have fail me (I have look up various grammar tree) so I am asking for help on devrant. Grammar nazi are warmly welcome :)
S -> NP VP | S Conj VP | S Conj S
NP -> N | Det NP | N PP | Adj N | Det Adj N | Det N
PP | Det NOM | Det N PP
VP -> V | V NP | V NP PP | V PP | V NP PP Adv
VP -> Adv V NP | VP PP | VP AVP | V PP PP | V
ADJP
PP -> P NP
AVP -> Adv | Adv Adj | Adv AVP
NOM -> Adj Adj N | Adj N | Adj NP
ADJP -> Adj | Adj PP
**I am not sure about these two clause below**
VP -> V | Adv
NP -> Adj Adj N22 -
