In bigger projects, you tend to miss type safety really bad, really fast. Rust has it built in, Python can have it bolted on. That’s simply one of the many aspects to consider when choosing your programming language.
But don’t worry about it too much. If one thing’s for sure, it’s that you will regret that choice in any case.
Yeah I usually love Python but right now I’m working on a paid project where I need to deal with tasks that are critical to mostly work on first try. Now, if it would be a different matter if my code was just completely idiotic and still worked but Python doesn’t error even when there is obvious typo that any statically compiled language could’ve picked up on a breeze at compile time.
I am scared to even implement a better logging system in my program because sometimes I forget to sanitize the arguments and my program fucking crashes at runtime because I added a new fucking logging statement.
I so fucking wish I had static type checking right now. The libraries I am using doesn’t have types (via annotations) so unless I spend days fixing their shit, I will have to continue with these shitty runtime crashes for the shittiest small mistakes. I also can’t trust these annotations because even if they are “wrong” their code coul perfectly work fine and they could even ship the wrong types. I would have the burden of dealing with their shitty annotations if that happens.
It’s like learning Perl back in the day, then needing to learn use strict;
Perl is a write-only language.
I used to love it, it could look a lot like c, or you could do crap like
$_=<<'';y;\r\n;;d;$_=pack'b*',$_;$_=eval;$@&&die$@;$_
Admittedly, they’re trying to obfuscate it, but even unpacking it a bit, it looks alien.
It works and is a pile of jank - Python
It doesn’t work and is a pile of jank - C++
You violated gods laws with how bad your code is and it still runs (right through the wall) - C
a compile-time error is highly preferable to a run-time error
Rust is completely correct to be a dick about it as well. Type safety is there for a reason.
Edit: for any possible future readers, there is a sensible default that I hadn’t found yet during this work in progress. It’s just in a different struct:
SaltString::generate()
.I’d like it better if things were designed to work together better.
Right now, I’m working on a password storage system using the
password_hash
crate. You need to provide the salt yourself; this is already a bit silly for not providing a simple default that just gives you 16 bytes from a CSPRNG, but let’s continue.You read the Salt struct documentation, and it talks about UUIDs being pretty good salts (well, using v4, anyway). So that pushes you toward the
uuid
crate, right? Except no. That crate doesn’t produce formats that the functions on the Salt struct will accept, like base64. So maybe theuuid_b64
crate will do it? I don’t think so, because that crate uses a URL-safe version of base64, and it’s not clear Salt will take that, either.You’re now forced to use a cumbersome interface from the
rand
crate to make your salt. I’m still working through some of the “size not known at compile time” errors from this approach.All of which would work better if there was a little thought into connecting the pieces together, or just providing a default salt generator that’s going to do the right thing 90% of the time.
Don’t get me started on how Actix hasn’t thought through how automated testing is supposed to work.
You know, I always wondered what the original image looked like, and even trusty Know Your Meme doesn’t show it. It looked like this:
Hey at least it’s not JavaScript which is perpetually high on crack with Object object
Well, that happens when you don’t override the
toString
method. Not worse than Java’s 0xf00cuHey, javas default toString gives you two informations:
- type, not that the class names in many java projects are informative
- identity, while the pointers are gibberish you can see if they are the same gibberish
1 + 1 = “11”.
[] + [] = “”
You wouldn’t typecast a car.
I may be on the wrong side of history but I can’t see what other role a car could get in the film industry except vehicle.
What about typecasting to a car?
For our American friends: the Opel Corsa is a car.
Debatable.
For the Brits, it’s a Vauxhall Corsa.
For everyone : it’s a sh’tbox (never again)
Perl when I iterate over an object and treat the result as a hash reference: “fine, whatever. Fuck you, tho”
And that’s why I don’t use Python for anything more than simple scripts
Look at mister “Sometimes I write programs that have more than a single niche function” over here
This is a post about growing disappointment with Python

int main() { const char c = ‘c’; char* pc; char** ppc = &pc; const char** pcc = ppc; // Error: not the same as cv-unqualified char**, no implicit conversion. *pcc = &c; *pc = ‘C’; // If the erroneous assignment above is allowed, the const object “c” may be modified. }
Please stop, I have CPTSD.
as long as you can shift it
Do we need any more proof Python is superior?
(I’m ^joking, ^I ^love ^Rust)
You don’t even need to cast in Python, a reference is a reference.
Python doesn’t have casts and is strongly typed.
Did you a word?
