Android : devRant is consuming too much power in background
Me : Say what ??
A : I said devRant is consuming too much pow.................
M : Who the fuck told you to rant about it
*Turns the phone off
No one speaks ill of devRant and lives long enough to tell about it.5 -
At a job interview.
Them: Can you please write a function that calculates fibonacci numbers on the whiteboard please.
Me:
fib=_=>($=>$.round(($.pow((1+$.sqrt(5))/2,_)-$.pow(-2/(1+$.sqrt(5)),_))/$.sqrt(5)))(Math)18 -
While testing the newly discovered "primesieve" C library, I forgot to change the limit variable from 1e10 to just 10 when giving the value through pow to make it more explicit.
Now my PC is dying in front of me while trying to compute the Gogol nth prime number. Nice.3 -
My work gave me three laptops because not one of them can access all the resources I need. So I have to balance my workflow around these three machines.9

Forgot to bring me laptop to college, so had to use the age old Turbo C complier on college PC. So had to do some power calculation.. used the pow() function, forgot to include math.h...
And bamm!!! It compiled and I had no idea why the pow function isn't giving the correct value!!
Lesson learnt: never trust anything!!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.

Fuck companies that want you to build new systems that are a superset of what they already have when they can't even tell you what they have now. Fuck you with your bullshit, nonsensical, self-contradicting, third-assed diagrams--some half-UML, half-clip-art, half-pie-chart drivel. If you're the CTO of a company and you want me to think long and hard about rebuilding your distributed systems, you can think long and hard about expressing what you already have. And NO: a verbal explanation pow-pow WebEx over your DSL connection with your protege that mumbles worse than an Atlantan rapper doesn't count as fucking "knowledge transfer" of your fucking architecture, FOR FUCKS SAKE.

wow!!! it's been long but i had to rant this........My course's teaching assisstant gave me a fricking B in his Interrim assessment all because i used the pow() function in php. He said it's only available in C++ so im wrong about the whole question.2

Why do tech writers always produce deliverable documents in Word files instead of Markdown, LaTeX, or anything that is easy to CM? It would be easier to track revision history and dump out of the CI/CD pipeline to the customer.4

When you are trying to install pow for like 2 hours unsuccessfully previous day and today in like 5 mins finally made it....

The ability to generate to generate all of my data transfer objects/, data persistence objects/entity, and unit tests for those.
I love having solid data models before I begin to work with behavioral models but it's a lot of manual work.
