That's fine, but rate limiting is a solved problem at this point. They need to rate-limit free accounts and be realistic about their limits instead of letting the system fail.

There is no difference between “def f(x={})” and “def f(x=dict())”, unless you have shadowed the dict builtin. They both have exactly the same subtle bug if you are mutating or return x later.

You can use “set()”. Introducing more weird special cases into the language is a bad direction for Python.

This is something you see in movies. Cash is by nature not traceable, so invalidating notes after issue would make it impossible to trust any cash transaction.

Not sure what you mean!? Locks, at their core, are not implemented by languages. They’re feature of a task runtime e.g. Postgres advisory locks or kernel locks in a Posix OS.

by rand_r 1y ago
Race conditions are generally solved with algorithms, not the language. For example, defining a total ordering on locks and only acquiring locks in that order to prevent deadlock. I guess there there are language features like co-routines&#

Yes, exactly. Latency is the killer feature. Doing a video call with extra 50ms of latency is noticeable.

Nothing prevents explicit error handling in Python either. Forcing explicit error handling just creates verbosity since no system can functionally prevent you from ignoring errors.

Interesting! I wonder how this plays into AWS pricing. They charge a flat fate for MBps of IO. But I don’t know if they have a rule to round up to nearest 4K, or they actually charge you the IO amount from the storage implementation by trac

I know what you mean, and you’re probably right, but there’s a deeper problem, which is the overuse of adjectives and overall wordiness. It’s quite jarring because it reads like someone trying to impress rather than get an important message

This is sort of an aside, but a very interesting thing about Postgres is that it can efficiently combine independent column indexes together, so there is much less of a need, compared to older databases, to even create multi-column indexes.

Something I’ve been curious about recently, is how did Linux get away with straight C for so long, considering how complex of a project it is. Did they end up reimplementing a bunch of C++ features? Actually, regarding sophisticated project

Using hardware floating point types is not suitable if mathematical correctness matters, and is largely a deprecated practice. Check out Python’s fraction module for example, for exact arithmetic[0]. [0]: https://www.geeksforgeek

It is true that DB compute is relatively expensive, but doing a join on the DB itself is obscenely more efficient vs doing it manually in a nested loop on an app server. Also, the DB is generally a lot smarter than doing quadratic operation

Yes, exactly! We found out the hard way just how unreliable Redis-based locks are, and switched to Postgres locks. It works reliably since our code is already in a Postgres transaction. Created a “lock” table with a single string key column

Development speed and conciseness is what sells Python. Something simple like being able to do `breakpoint()` anywhere and get an interactive debugger is unmatched in Go.

Well the 192 case would probably have an external IP + Port uniquely mapped to it in the router’s NAT table. I think you’re missing the larger point though. No one said IPs are exclusively used as GUIDs. Just that they are used as GUIDs, wh

by rand_r 2y ago
Because of NAT, it’s actually “IP + Port#” that is globally unique, and ultimately associated with a single physical network interface on a device (e.g an ethernet port on a PC). There’s exceptions like broadcast IPs, but the point is that

I’m not a fan of the control, but this is the free market at work. Nothing stops you or any other company from creating a competing phone with its own app ecosystem. It’s really not for the government to dictate to companies how their produ
