Agreed. Raw threads are almost always the wrong application-level concurrency abstraction. Actors/Erlang-style concurrency and futures are both much better abstractions for application programmers. I'm also a big fan of threads

I'm not following these things because I realize I really don't want to spare the time to dig deeply enough down the rabbit hole to find the truth. However, it doesn't seem difficult at present to find a workable pretence fo

GP is talking about the Linux kernel's buffer cache. Unless you tell the kernel to operate directly on the disk, your reads come from and your writes go to pages within the kernel's buffer cache. Using a small bs probably result

Err... sorry... bumping once in each of the directions is linear in the number of dimensions, not exponential. You don't bump all combinations, just one dimension at a time. In any case, the savings from automatic differentiation are

I wonder how much auto-correct is going to cause relatively rare words with a small edit distance from common words to slowly leave the English language.

Yes, "laziness" is unfair and imprecise, a laziness on my part. :( I think it was an issue of familiarity and comfort, not newness. The author joined Google before I did. If you're basically working with one other person, a

The author was born and raised in Brooklyn and went to Cornell, if I remember correctly. As far as I know, English was his only language, and he was almost certainly using either US QWERTY or Dvorak keyboard layout.

That's a fair criticism. Deep down, I usually have a pretty high opinion of my abilities. I think I'm pretty good at hiding it in person, but I'm less good at hiding it in my writing. I feel happiest and most excited to wr

The "yelling" was coming to the team email list, asking for ETAs and progress updates for when real-time risk would be back up. Roughly 4 people at the time knew the bug could be traced to the new guy's commit, and none of t

I grew up in the upper Midwest, went to school outside Boston, and spent most of my adult life in New York and Hong Kong. I haven't spent much time in California, so maybe I'm placing too many of the cultural problems I saw at Go

This was in the Borg days, pre-Flume. As I remember, we had at least one Borg cluster to ourselves for indexing. Our quota was a cluster. We cared because indexing latency is important. Engineers get paged and woken up in the middle of t

I think that maybe the author felt like finding the end of a loop stood out much better that way, instead of trying to distinguish the ends of conditional blocks from the ends of loops. If you're used to poorly formatted code in an ML

It helped me empathize with young engineers dealing with their first high responsibility bug. About 4 years ago, I was managing a guy right out of school who pushed a minor bug that broke real-time risk calculations for a major multinationa

I was a couple years out of school, and felt a lot of responsibility. It wasn't really a big deal, but it didn't feel like it at the time.

It wasn't the best way to criticize the code review. If I could go back in time 15 years, it's also not the first mistake I would fix. It stuck in my mind because I felt bad about it. I was frustrated that I had been hounded to

There's a good deal of responsibility in writing code that is going to run over every single page (and PDF document, MS Word doc, the higher ranked Flash animations, etc.) in the visible web. For my part, I once made a bad assumption a

Ironic, from the authors of RE2. They know the correct way to implement regexes. Though, when I worked on Google's indexing system, some researchers were having machine learning generate regexes to run on every page in the visible web

To be clear, you're asserting that by donating $1.1 billion in cash, they're likely getting more than that sum multiplied by their marginal tax rate in tax reduction? I'm honestly curious what the loopholes would be.

by KMag 4y ago
There are some loopholes with donations, mostly regarding difficult-to-value benefits and also around donating dificult-to-value things rather than cash, stocks, and/or bonds. But, if you donate $1.1 billion to an eligible charity (and
