With the number of people who go through Google's interview process, this might actually change the industry to think more carefully about the interview process. If Google isn't making whiteboard interviews the norm, who will kee

But that's also why BPF doesn't seem to have a place in this world. Anything surfaced by a BPF program should probably be surfaced by a proper kernel module or syscall. As far as I can tell, the utility of BPF tracing is solely

That's not how HTTP works. HTTP is a transfer protocol, and is not so opinionated on the semantic meaning of the Data it moves. HTTP, HTTP/2, and HTTP/3 were designed to be backwards compatible. It would break that comp

I want to like BPF, but so few of my problems are in the kernel. Performance problems are usually at the application layer, either in my code or my dependencies. Even in the rare case that it something outside of my control (like the comp

This would not work, too many websites (perhaps wrongly) depend on this string.

There are wrong reasons to sniff the UA string, and less wrong reasons. If a Browser has a bug that gets fixed in later versions, sites have to sniff the UA string to do the right thing. For example, a browser bug may cause people to se

Java does something similar, decaying its HashMap into a binary tree after enough collisions.

That's not what big O notation is about. It represents the growth rate. In a the case of a hash table, the size of the thing you are hashing is not affected by the number of items present in the hash table. Putting a trillion bit

Yes, they still need unlimited kernel threads (for liveness reasons). When I asked a few years back about this, go-nuts@ suggested implemented my own rate limiting in application space. In my case, it was for running Go on a resource cons

Disney is in a tough spot since they also pay dividends. Companies typically don't ever reduce their dividends, which leaves Disney unable to spend that cash on their growth.

It's poignant to watch Go slowly realize the why other languages have more powerful, more useful error types. The `error` interface is anemic to the point of uselessness. Making it unwrappable is step forward, but all that does is pr

I didn't come to appreciate the power of USB-C until I started using it with my laptop. It is a single cable that connects to my monitor, powers the laptop, provides USB access to the keyboard and mouse, and to the hub on the monito

That is a lot of moving parts for a toaster. It seems like even a few crumbs falling into the wrong spot would jam the falling/raising mechanism.

There are more than 100k TVCs at Google. I don't think you can speak generally about them, because there is high diversity in their job roles.

They were previously allowed by the IP RFCs, but limitted by the kernel. They are in the 0/8 block.

It may not be the first but it is a reason to upgrade from HTTP/1.1. PING frames have other uses too, like being able to estimate connection latency in an application, rather than trying to read it from the kernel. This can be used t

A cool thing HTTP/2 provides is PING frames, which allow clients and servers to check if connections are still alive. In case your application can't turn on TCP keep-alives, you can enable it at the application layer. This al

It's needlessly complex because it doesn't solve any problems I have or any I have heard of. A simpler auction would still work pretty well, and be more easily understood by participants. I ask because the only case I can think

That's not right, you (we) get accurately priced securities. We also get tighter bid-ask spreads.

Without having read the regulation, why don't institutional investor just make a private market place where they can trade for sub-penny values?

This seems needlessly complex. Aside from being an interesting thought experiment, what is the practicality of this style auction?

Exchange traded funds depend on special traders who buy the underlying stocks (like AMZN and MSFT), and sell them in exchange for the ETFs (like SPY and VOO). If the individual stocks are more valuable the special traders can buy the ETF s

I found it surprising that atomic operations in Java are converted in to locking when compiling for some versions of android. The guarantees of Java (before 9) on ordering are slightly too strong and result in locks being used under the ho

The correct term to use here is blocking. The hardware bus locks finish in a bounded amount of time and allow the other processors to eventually make progress.

Do the seams need to be continuous? Intuitively it feels like the seam being carved out doesn't need to be made from pixels touching each other. What if the best seam has a slope of about 1/3 (i.e 1 vertical pixel for ever 3 ho

If your DC had limited rack space it might start to make sense. Buying a cheaper processor means you would need more of them to accomplish the same amount of work, but also you need more space.

Perhaps we could combine the two? Make a slot machine that pays out in penny-stocks, rather than chips.
