Sometimes a question can be so simple you'll think it's a trick question. Saw this on YT short youtube.com/shorts/cPmknFp…
- C is an important language to learn for every developer. - It's easy to learn, but using it correctly takes time and experience. - Rust is not as easy to learn and you can start using it correctly right away (when you actually learn how to use it).
Just published a post on how I processed a 14GB file 78% faster with Node.js! 🚀 I share my journey of buffer optimization, byte-level parsing, and other techniques that led to this massive performance boost. Check it out! 👇 @ThePracticalDev dev.to/pmbanugo/nodej…
You’ll probably never have to prove mathematical statements in your line of work, but learning how to write math proofs will teach you to write in a way that is: unambiguous and convincing Unambiguous and convincing is not the same as clear and persuasive — which I will get to…
An email from one of my readers in response to my recent @nodejs blog post. do you think Node+WASM would get you something much better? Maybe I should finally try WASM 🤔
Processed 1 BILLION rows (14.8GB file) 4.7x FASTER 🤯 with a single-threaded Node.js. How? *Byte Parsing *Integer Math *Used hashing to keep Map lookups fast. Full technical breakdown and code in the linked blog post:
Working with very smart people who are humble and generous in character is a huge flex.
You can write an article and be like, "yea, this is so good." Holop, don't say that yet 😂 That is just the beginning, your "so good" article is about to be totally destroyed and rebuilt, so you can actually say it's so good for real.
The effort that goes into writing one @RareSkills_io article is mindbogglingly thorough. Every single article is designed with care, patience, and dedication. Every word, and phrase is read by reviewers from 20+ perspectives and ensures it's so clear it can't be misconstrued.
Here is a more correct diagram and code illustration showing the pointer and variable has distinct addresses, thanks to @isocroft 🙌 who helped clarified this. But the claim is still remains though.
It's confusing at first but it all makes sense when you pointer arithmetic kicks in. I think Rust has pointer arithmetic in unsafe mode
The name of the array in C is a pointer to the first item in the array. I find this behaviour very confusing, what is the purpose?
People will go to any length to find something to criticize about Rust. It must feel good for a language to be treated like the 'perfect' standard. --- Open the GitHub link, view the full discussion.
Ubuntu’s plan to replace the GNU Core Utils with Rust-based reimplementations is going exactly as poorly as predicted. Some Rust versions being 17 times slower than the battle tested GNU C / C++ version. And other Rust-based versions simply failing to work on large files.
6 months later, I kept my word. Not only was RareWeek high signal — lead auditors from top firms attended — it was also high effectiveness and high fun. In six days, people went from not knowing anything about ZK to coding ZKVMs, building hash function circuits from scratch,…
300 likes and I’ll host a high-signal dev/auditor-focused event in Bali. Maybe we’ll have a week at a resort where I teach ZK. Maybe side-events only, no one event can cater to everyone. Since many of my Indonesian friends are restaurant/hotel owners, I can get the EOs insider…
C feels simpler here. Only thing that trips me off is how scanf uses `lf` precisely for a double while printf uses `f` for either double or float. Rust lets you always read a String first and then .trim().parse::<f64>().
Rust forces you to accept string input and then parse it to whatever-type. In C, scanf directly reads formatted input into the expected type. C is simpler on the surface but will require much more extra effort to avoid unexpected runtime error.
One of my very first C code in comparison to Rust. I plan to write a Rust version of every practice problem. Rust doesn't allow implicit type coercion, C does.
2. Practice. A lot of it. Theory alone won’t get you there — you need to build muscle memory. There are two types of practice that helped me the most: – 🧩 Mini challenges to reinforce the basics – Writing small but complete programs to connect concepts together For the…
