Can't wait for 3 weeks from now when the Bluesky media blitz putters out.

My dad subscribed to these for many years from the 50s-70s. I used to sit in our attic reading old issues, with projects based around vacuum tubes, transistors, lasers (!) and even…

As pretty much any professional trader or quant knows, there are degrees of efficiency. Ex-US markets are significantly less efficient than the US. Some US securities are less effi…

I loved this retell. Brings back the old days, especially the Google and Yahoo parties of the late 2000's. Those were crazy. They literally carried one of my employees out of a bas…

Plato was in fact real... I used it many times! Looking back, it was pretty impressive technology for its day but was quickly becoming obsolete. I hated having to walk all the way …

Banks would actually be of primary concern after a nuclear war. Without them, there would be little economy to speak of.

My guess is that something that important was protected by reinforced ceilings/floors.

Interesting story but I have a bit of anecdotal evidence to share. Back when I was a Freshman at UIUC in 1989, I was given a campus tour and told that one of the buildings there wa…

Yes, that's what people typically use a calendar for. So you agree that this trick isn't useful for anything?

Neat but what is this useful for?

I have a recent OnePlus and it's been excellent. I like it even more than the older ones I had, which is directionally quite different than my experience with Apple and Samsung.

Pahole is a related utility for high performance programmers. I've been able to attain orders-of-magnitude performance improvements in trading applications using it.

I don't know what caused it but I suspected at the time, and still do, that it was simply business people getting more involved in order to drive growth. The hostility was simply t…

Phenomenal article, very entertaining and aligns with my experience as a prominent search "outsider" (I founded the first search intelligence service back in 2004, which was later …

>I don't do much C++, but I have definitely found that engineers will just assert that something is "faster" without any evidence to back that up. Very true, though there is one ca…

I had a section of code which incurred ~20 clock cycles to make a function call to a virtual function in a critical loop. That's over and above potential delays resulting from cach…

Is this really efficient or practical? My understanding is that the latency required to copy memory from CPU or RAM to GPU negates any performance benefits (much less running over …

This is out of the question for real time apps. Co-routines are an elegant solution to implement cooperative multitasking in such cases.

Ha, we used to do this in the 90s with double pipes || and triple pipes |||.

I created an over-the-top Catan game. I started off with a faux treasure chest from HomeGoods. Then replaced the generic board and tiles with laser cut wood ones. The robber was re…

I like where this is going. Keep it up. However, I wonder if it wouldn't reach a far greater audience in C++?
