I upvoted your first comment because I felt that you were making a valid if controversial point. But the concept of "handing over" Ukraine really underlines why the rest of the world views Russia as such a threat to world peace. U

Disagree that the statistics I cited have water availability as a prerequisite to improvement. California can simultaneously have water problems and graduate more seniors. They are not mutually exclusive. Agree in the need to ramp up water

That's very interesting. Today I learned.

I agree so strongly with this sentiment. There is always such a defeatist attitude on these threads that assumes California is somehow full and unchangeable. Outside of the three metro areas, it's basically empty! Separately, in the me

I have a pet theory for this phenomenon. If you look at recently contacted peoples or those who have little contact with the outside world, endemic warfare is common. In these societies, well over 20% of men are killed in the ongoing confli

Could you expand on that? I'm not familiar with the world of rooting android. Does something exist that would allow you to specify exactly which apps are installed (and remove the web browser and play store)?

I'm with OP in their diagnosis of the problem. Other commenters seem to focus on "tricks". The problem with these tricks is that they can all be bypassed and you always go back to normal. Would you suggest someone who wants t

This is almost certainly wrong but is worth a mention given that the author can't figure it out. In Southern India, there is a language known as Kannada. It has 43 million speakers, which, fun trivia, is more than the population of Can

The only reason why Bitcoin energy usage is so high is because the difficulty is automatically adjusted so that the average time between blocks is approximately 10 minutes. Any attempts to improve the energy efficiency, rather than reduce t

Yup. Considered it. I initially settled on no because it might compromise the design goal of 1:1 MongoDB/PyMongo compatibility. Now the idea is being revived as an option alongside the two existing backends. I am concerned there might

O(n) cache size is fine (and IMHO, preferable) for small datasets. For large datasets, you're correct. Cache eviction is important when memory usage gets too high. I didn't have it explicitly on the README as something that needs

You're right. Fixed. SQLite is more-so the winner but Mongita appears to squeak ahead in id lookups https://github.com/scottrogowski/mongita/blob/master/assets/... (to be fair, it might be the

by scottrogowski 5y ago
Thanks for the kind words :) I like your idea. As I understand it, since SQLite performs better on most benchmarks anyway, why not have an engine subclass that utilizes SQLite itself? This would be a little trickier than your envisioning. T

I think as I understand it, your question is whether we can't just put a distributed layer on top of basic embedded databases. This is really interesting and is something I came across while writing this. It turns out that concurrency

Hey, your first statement is true but your second is not. The disk engine does store data in memory which is part of the design. You wouldn't want to use a database that doesn't utilize caching. The last benchmark panel, https:&#

This is good and helpful feedback. Thank you. I'm humbled by how well this has done so far but definitely feeling the criticism. A title like, "Mongita is embedded MongoDB for Python", while being a statement without ambiguit

by scottrogowski 5y ago
It's a good question and to be accurate, depending on the benchmark, Mongita is about the same speed at SQLite to several-times slower. There is less happening algorithmically than you would think. Where the tricky slow bits do exist,

Author here. My goal with that one-liner was to convey immediately what it is - an embedded database that implements the PyMongo/MongoDB API. Is it semantically perfect? Probably not. Will Mongita be useful to Python developers who are

by scottrogowski 5y ago
Thank you! I actually did consider doing exactly what you said. Early on, I decided one my goals for the project would be to make it easy to swap back and forth between Mongita and PyMongo/MongoDB. For me, that meant getting as close a

Author here. That's exactly it. I think it would be very difficult to completely beat SQLite with a Python library. My goal wasn't to beat it but to have performance that's within an order of magnitude which I think I've

by scottrogowski 5y ago
That's a good question. I'll try adding it to the benchmarks.

I have a genuine curiousity (because I can't seem to find it in the news reports). The contract is going to the starship design. What exactly are they planning to take that requires such a large ship? The lunar landers were tiny becaus

I'd be curious to see whether we actually see an uptick in cancers in the coming months/years. If so, I wonder whether it will turn out that using hand sanitizer resulted in a net increase or decrease in overall mortality. Evidenc
