A forum for software engineers
Work through code, together.
Jimineering is a community where software engineers collaborate, talk through code and solve problems side by side. Bring a question, a pull request or a stubborn bug, and leave with a clearer answer.
For professionals and learners, 18 and over.
Why does my counter lose updates when threads share it?
self.value += n reads, adds and writes in separate steps, so two threads can overwrite each other. Guard the update with a lock:
1import threading
2
3class Counter:
4 def __init__(self):
5 self.value = 0
6 self._lock = threading.Lock()
7
8 def increment(self, n=1):
9 # One thread at a time past this line
10 with self._lock:
11 self.value += n
12 return self.valueAn example of the kind of answer you’ll find on the forum.
What you can do here
Everything is built around getting to a working answer, and learning something on the way.

Ask questions, get accepted answers
Post what you’re stuck on with the code and context that matter. When an answer solves it, mark it accepted so the next person finds the fix right away.
-
Get your code reviewed
Share a function, a query or a whole approach and get thoughtful feedback from people who have shipped similar work. Return the favor when you can.
-
Find your corner
Conversations are organized into focused categories, so you can follow what you work on and skip what you don’t.
