What would you search for, the zero/root in the derivative? Imagine the derivative is a function like y=x^2-eps with some small eps, say 0.000001. For binary search like that to work, you need to start with two values x1 and x2 such th

If you're interested, I wrote a more elaborate comment on asyncio vs. multiprocessing vs. multithreading here: https://news.ycombinator.com/item?id=36915581 (fyi, Python's multiprocessing has support for interproc

More precise wording would've been: "It's still really easy to write code that runs into race conditions". The race conditions are rare, but code that (rarely) causes them isn't.

I don't think this is true. There are fairly strong voices on both sides inside the community, at this time it's pretty uncertain. To quote Guido: >Let’s not blow it this time. If we’re going forward with nogil (and I’m not sa

In Python, asyncio and multiprocessing packages can get nearly the same or better performance for IO- and CPU-intensive tasks respectively as no-GIL multithreading (and are more performant than GIL multithreading), with only a tiny fraction

Quoting my comment from elsewhere: >I didn't dive deep on this, but I assume that GIL mode can still run anything, including no-GIL code (it is one of their promises, at least). So, unlike 2->3, there is forwards-compatibility.

Stores like that, while scaling well, are orders of magnitudes slower than CPU memory. The kind of application I was thinking of is more compute-intensive, eg. image processing or fancy algorithms.

It's only about performance. asyncio is still inherently single-threaded, and hence also single core. multiprocessing is multi-core and hence better for performance, but each process is relatively heavy and there's additional over

Heads-up, the parent edited their comment to remove that sentence and added some "convincing" instead, so that's why your comment looks out of place.

The GIL does very little to protect unexperienced users. It's still really easy to run into race conditions, for example, if your thread gets scheduled out in any multi-instruction operation (this is more common than you think [1]). In

You would replace the Fastly CDN with Storj, correct? Your link mentions 1500TB of Fastly traffic, which would cost $12k with Storj. Not sure if this is related to parent's 3TB/day number, but I went with that when I estimated the

Using the pricing from your other comment and the numbers from the parent, if I estimate correctly, Storj comes in at about $8k/month? That's cheaper than AWS (considering there are no CDN costs), roughly on the same level as Clou

When they bet on bonds, they essentially bet on the government not to default. When they bet against bonds, they expect a sovereign default, which would be terrible for everyone involved.
