Honestly, 2200 LOC is really not very much. I’ve dealt with 15 kLOC source files before, and have seen upwards of 30 before. I don’t think breaking it up would add much in the way of clarity given the volume of code, at that point splitting

I’m a little confused, how can a file name be non-decodable? A file with that name exists, so someone somewhere knows how to decode it. Why wouldn’t Python just always use the same encoding as the OS it’s running on? Is this some locale-rel

To be honest, I thought Diablo Immortal was pretty good if it weren’t for the micro transactions. The fact that it was a free game made certain parts super slow and grindy to incentivize purchases, but if it were a real game you have to buy

I’m curious why not implement websockets into Postgres natively instead of relying on a proxy server? Wouldn’t that be the way to minimize latency?

You can also dramatically reduce the latency by testing before attempting the CAS, which will switch a lot of cache line requests into Shares instead of Owns. I didn’t see it in this implementation. But the point of the wait/notify in

An interesting thing to try with the two-bit mutex is to add exponential back off. I suspect it’ll dramatically improve the latency under contention. Another interesting thing to point out is that there seems to be a crossover point between

As a kid my dad told me that I could name my variables whatever I wanted. I still remember the confusion on his face when he saw “int iPod” and “string xbox” all over my code.

Not sure how it is elsewhere, but at least in Seattle we always have pay stations set up anywhere you have to pay to park. The pay by phone app is merely a convenience, and isn’t required at all.

In StarCraft 2 there’s the opposite problem: invisible units make a slight ripple that you can pick out. On low graphics the ripple of invisible units is basically unnoticeable. But if you turn the effects setting all the way up while keepi

I went from preschool to second grade, and I thought it was OK. My teacher in first and second grade was really mean to me which caused me to beg my mom to let me go to public school as I was not willing to go back for a third year of that

I think technology has advanced a lot since then. I see videos of peoples’ transactions on the lightning network being confirmed within a few seconds. It’s taken off in a lot of markets in poorer countries from what I understand.

A while ago at my company we switched from GCC to Clang, and noticed a couple of massive regressions (on the order of 50%?) in performance having to do with floating point. After profiling for a bit, I discovered that suddenly a lot of time

1000x yes. I always complain how JIRA is unintuitive, clunky, and confusing. But all of that would be fine if it were fast, because at least I’d be able to try more options faster figuring out which button it is I actually wanted to press.

The letter Z (pronounced like zed by some people) is used as a symbol of support for the war (a lot of Russian vehicles had a Z on them for some reason). Zed-turbo-patrioting is then probably the act of being extremely patriotic and in supp

The problem with your analysis is that you're using big-O notation. Big-O notation is based on an abstract machine that is pretty unrepresentative of real computers. In practice, the memcpy is always going to be faster (until you get t

I first thought this was an announcement about how R now uses Posits instead of IEEE-754 floats… I wonder if the rebrand will cause any confusion for either party down the line.

I think the fundamental limitation is that a small character limit removes the opportunity for nuance. It is a trade off though - not many people will spend time reading nuanced essays. I’d say this is a big part of the polarization - there

Wow this is amazing! I wish I'd known about this when I was trying to hack an optimization into a fork of GCC in undergrad years! What really excites me though is this: I've frequently noticed a big tradeoff libraries make between

I’m a bit skeptical of this figure that chess grandmasters have admitted it. From what I understand, if chess.com accused you of cheating, they tell you “you have 3 days to admit it or be banned”. So in the face of that, of course they’re g

I agree on some level, but I think if you’re intentional with your design you can get by with a very simple arena allocator where an allocation is a single subtraction from a pointer. In my experience, most programs have a few long-lived da

The OS doesn’t actually map/allocate the pages to you until you touch them, so if you preallocate 30 GB and only use one row, you’d only be using 4 KB (or whatever your page size is). This is the same as if you’d individually malloc’d

I like this a lot! I’ve been trying to find ways to avoid memory allocation as much as possible in my projects as well. So far I’ve settled on mmap-ing large slabs at a time and arena allocating (Linux’s mremap makes growing the allocation
