Ever think your AI coding buddy (like GitHub Copilot) could be tricked? 🤔

Researchers discovered a "Rules File Backdoor" where hackers hide malicious prompts in shared config files. The AI reads these hidden instructions & injects bad code, while the developer sees nothing unusual. Your assistant, weaponized!

Coming to realize that 98% of my professional life as a #software #developer can be summarized with two songs:

- Rubella Ballet - False Promises
- The Hives - Hate to say I told you so

I'll let you know when I find out which song covers the 2 remaining percents but it won't be a balade...

Ok, fellows #developer #coder #programming #Python

What is the result of this code

Please do not execute it, just guess it.

Tomorrow the answer and the reason ;)

Answer in here:
mathstodon.xyz/@liso/114347620

```python

a = 123
b = 123

c = 456
d = 456
(a is b , c is d)

```

MathstodonOxLiso (@liso@mathstodon.xyz)Attached: 1 image WoW 58% correct answers! But you probably are wondering why is this. So, the answer is "Object Caching". Python, in its reference implementation Cpython, makes some pre-allocating on some objects for efficiency. And in this case, with small numbers, Python has always the values between -5 and 256 already reserved in memory. So, when you create a new number in that range, it always gives you the same reference. You can check it with the id(x) function, like in the attached image. But remember, this is for cpython. Maybe it does not work the same way for other interpreters like ironpython, pypy or jython. Btw, you can check this in the cpython code: https://github.com/python/cpython/blob/c35c7353eb8fbccff2d3a6ab664426b31af00d4d/Include/internal/pycore_runtime_structs.h#L109 and https://github.com/python/cpython/blob/c35c7353eb8fbccff2d3a6ab664426b31af00d4d/Objects/longobject.c#L27 #happy #coding
