C compilers don’t really disagree; the C standard allows implementation-defined behavior, so libc functions vary across platforms. That’s why functions like printf or strcpy can differ, and strncpy is confusing because it may not null-terminate and was never meant as a safe string function.

Why C compilers can't agree in how a standard C library function should works? ☹️ And better not to talk about strncpy()...

@SakshiSugandhi A library is code you call when you need it. A framework controls the flow and calls your code.

@straceX This C program writes the string `"user:42=example\n"` to a temporary file in `/dev/shm`, closes it, then reopens the file for reading, reads the content into a buffer using `fgets`, and prints it to standard output before exiting.

fun fact: linux already gives you a zero-dependency in-memory store it’s just /dev/shm > a RAM-backed filesystem that’s been around forever you can literally write to it like a normal file and read it back for small local data, it’s surprisingly fast not trying to replace Redis, just a simple trick when you don’t need extra stuff

@mitchellh That’s tough to read—GitHub won’t feel the same without voices like yours. Wishing you the best on whatever comes next.

Ghostty is leaving GitHub. I'm GitHub user 1299, joined Feb 2008. I've visited GitHub almost every single day for over 18 years. It's never been a question for me where I'd put my projects: always GitHub. I'm super sad to say this, but its time to go. mitchellh.com/writing/ghostt…

@SumitM_X This code throws a ConcurrentModificationException because you’re removing an element from the list while iterating over it with a stream, which internally uses an iterator that forbids structural changes during traversal, so the program crashes before printing anything.

What will be the output? List<String> list = new ArrayList<>(List.of("a", "b", "c")); list.stream().forEach(e -> { if (e.equals("b")) list.remove(e); }); System.out.println(list);

@SumitM_X Remove React.strictmode in main.jsx file

Why does useEffect run twice in React 18?

@EOEboh Setting a very long JWT expiry is risky because a stolen token remains valid for a long time, giving attackers persistent access. Since JWTs are stateless, you can’t easily revoke them. Use short-lived access tokens with refresh tokens to balance security and user experience.

Interviewer: How do you handle JWT expiry? Candidate: I just set a really long expiration time so users don't get logged out What's wrong here?

On a table with 100M rows, ALTER TABLE users ADD COLUMN age INT; can trigger a full table rewrite, causing heavy I/O, long execution time, possible table locks, temporary disk space spikes, and replication lag, which can slow down or even take down a production system if not handled carefully.

Interviewer: Why is this dangerous? ALTER TABLE users ADD COLUMN age INT; (on 100M rows)

Python Quiz: What is the output ?

@kotlin Kotlin makes null-safety the default, preventing many `NullPointerException`s at compile time without extra wrappers—perfectly integrated into Spring Boot for safer, cleaner backend code.

🔗 Kotlin treats null-safety as a first-class feature: types are non-nullable by default, so you catch potential `NullPointerExceptions` at compile time, without the verbosity of `Optional`. See how this works in a Spring Boot backend 👇 kotl.in/b74l38

What’s the difference between a library and a framework? If you can’t explain it clearly, are you really a developer? 😭

@PythonDvz Dynamic vs Static 🤣🤣

@PythonPr args packs (1, 2, 3, 4) into a tuple, and sum() adds them. Then the output is 10

Python Quiz: What is the output?

@PythonDvz `==` compares values, while `is` compares memory identity—so the result is **different**.
