It is possible, they like the experience of doing it themselves from scratch.
It is not an MBA's cost/benefit analysis

NEW BLOG: The Great VM Escape 💕
We caught threat actors deploying a VMware ESXi exploit toolkit in the wild - potentially was a zero-day developed over a year before VMware's disclosure 👀
If anyone has thoughts on it let me know, but I needed almost a full case of beer to wrap my head around this one 🍺
Full technical breakdown 👇

Alright what's the next thing we're all moving to when it goes to shit

@Franc0Fernand0 @lauriewired Multithreading bugs are hard
To begin: because they can't be easily reproduced.
English
@lauriewired Typically, bugs of this form are caused by invalid memory accesses or by thread races. The former are affected by optimisations, which rearrange the data layout in memory. The latter will be affected by timing differences between optimisation levels.
English
one of the trickiest C++ bugs I’ve experienced involved the *physical* location of data in memory.
writing some tricky string decryption code, it worked...sometimes
recompilation slightly shifted the layout of the stack, which by pure luck contained a “safe” number

@popovicu94 C is the natural language to use.
OSs were/are built in C.
0% adapter impedance

C is not just a language. It is sort of THE operating system interface when it comes to Unix and Unix-like systems (including Linux... maybe?).
We often debate "C vs. Rust" or "C vs. C++" as if they are just tools in a toolbox. But we overlook a massive structural reality.
For most of the world, the Operating System is the C Library.
Consider the difference between Linux and everyone else:
Linux is the outlier. It publicly documents its raw System Call ABI, allowing languages (like Go) to bypass C entirely and talk directly to the kernel.
macOS & BSDs are different. Their system interface is officially defined by Libc. If you bypass the C library and call the kernel directly, you are likely breaking the contract.
But it goes deeper.
POSIX is not an OS implementation standard. It is largely a C standard.
The POSIX specification doesn't describe raw syscall numbers or register values. It describes C function signatures.
* It defines printf(), not the assembly required to print.
* It defines , not the kernel trap.
To be a "POSIX-compliant" OS means, fundamentally, to host a C library (along with a bunch of shell utilities, for example, but that's a different topic).
Even if you don't write C, you are using it.
Python? The standard implementation (CPython) is C.
Java? The JVM talks to the OS and hardware via C.
Rust? It can only talk to the outside world because it mastered the C ABI (Application Binary Interface).
Can we ever leave C behind?
If the definition of the Operating System is tied to the C Standard Library, then "replacing C" isn't just about changing languages. It’s about redefining what an OS interface looks like.
Should we? Maybe. Memory safety issues in C account for a lot major security vulnerabilities.
We are trying to replace the Latin of computing. And Latin has a habit of sticking around.
Check this fascinating excerpt from the POSIX standard below. 👇
Two noteworthy bits:
"The C Language – The system interfaces and header definitions are written in terms of the standard C language as specified in the ISO C standard."
"Interface, Not Implementation – POSIX.1-2017 defines an interface, not an implementation. No distinction is made between library functions and system calls; both are referred to as functions. No details of the implementation of any function are given (although historical practice is sometimes indicated in the RATIONALE section). Symbolic names are given for constants (such as signals and error numbers) rather than numbers."

@magattew I'm a big fan of the USA and capitalism, but on numbers alone, hasn't China technically lifted more agrarian folks out of poverty than America?
English
If you actually care about poor people, you should care about the system that’s lifted more of them out of poverty than any other in human history.
That system is the free market.
Everything else is just feeling good about yourself while people stay poor.

"I'm going to sell a big chunk of my portfolio, pause my monthly DCA buys, and hunker down in a defensive position for a few months."
S&P500 grew 12% in the last 6 months, so if it continues, he misses out on this
Then when he decides "okay it won't crash now I'm gonna buy back in"
Then it actually crashes so he lost 12% return + crash vs just the crash if he remained in the market
English
Statistically it's unlikely he can time the market crash so he is likely to lose money by missing out on the gains that are still to happen
Also statistically he is guaranteed to lose money with this by missing out on the rise back up (which he also can't time)
The only one winning here is his broker who wins from all the fees of selling and buying
But there is a tiny odd he does bet it right

🔴 To me, the stock market bubble has popped. I'm going to sell a big chunk of my portfolio, pause my monthly DCA buys, and hunker down in a defensive position for a few months. So bookmark this post, so you can ROAST ME in a few weeks/months, because obviously the hard part is actually being right 😂 Reasons: - The market looks overvalued by basically every benchmark indicator I check (take a look at the screenshots). - There's nowhere to hide. AI? Inflated (even if it's absolutely the future). Real estate? Inflated. Gold? Inflated. Crypto? Inflated. - I'm struggling to find an investment where I can honestly say: "in 5 years it'll be worth more than it is now". - Leverage: FINRA margin debt ~$1.184T (Nov 2025) and +45% YoY - Buybacks: S&P Dow Jones reported a record quarter in Q1 2025 ($293.5B) and almost $1T in 12 months (Mar 2025). Paper and makeup can handle anything! How much longer can the market stay irrational? I don't know, but I'm stepping off. I don't mind missing some upside, but I'd be pissed to eat the big wipeout. And above all… intuition. I can smell it in the air, I can't explain it better than that. Please laugh at this sentence if I screw this up in the future 🤣 If I'm wrong, which is the most likely outcome, I'll admit it in a few months and that’s it. Then I'll just re-enter. The only reasonable positions right now, in my view, are strong currencies like EUR/USD/etc, or even better, a money market fund/ETF. For the record, as of today we're at: - QQQ: $612.21 - SPY: $681.68 We'll see when we reread this in a few weeks / 3–5 months 😉 Good luck!

I just spent 30 minutes to make unit tests in one of the C++ projects 3 seconds faster.
English
@ohmypy Of course all interpreted languages will be faster.
All statically-typed and compiled languages will take longer, it takes time to verify types, load libraries... to then later generate binary objects, link them to libraries, and finally execute another binary (just created).
English
Here's a little unscientific chart showing the compile/run times of a "hello world" program in different languages.
I used single-core, containerized sandboxes on an ancient CPU, so the exact times aren't very interesting, but relative timings are.

I just reviewed C++ code written by my Team Lead for the first time
