Link technologies in today’s data center networks impose a fundamental trade-off between reach, power, and reliability. Copper links are power-efficient and reliable but have very limited reach (< 2 m). Optical links offer longer reach b

If I peed in my pant (or in a similar awkward situation) and someone happened to have filmed it. What kind of legal rights (if any) do I have to remove my shameful moment from the Internet?

Great article that gets to the key points. The problem with "persistent memory bus" is a very bad sign by itself. This means no existing software/systems can benefit from the feature without writing some new code between the

Chinese dragon = snake with four legs. It can fly (magically). Western dragon = dino with wings. It can fly. They're unrelated things. A Chinese dragon is more like a unicorn than a western dragon.

It's the ideal cooker for me. I take shower only once per week and most of my gas cost went to cooking. It will save ~75% of by gas meter reading (but only ~15% on my gas bill though).

Just tried to insert 100M KV pairs of the same data format in a KV store. It takes about 26s on a Xeon Silver 4210, including fully writing down the data to the filesystem/SSD. The source code can be found here: https://gith

I started to use const whenever possible after being familiar with some compiler optimizations and the Haskell pl. The point is knowing how to give the compiler an easier job.

Sending those patches is just disgraceful. I guess they're using the edu emails so banning the university is a very effective action so someone will respond to it. Otherwise, the researchers will just quietly switch to other communitie

In addition to code reduction, this may also help reducing occupied branch prediction slots (mostly x86 I guess?). Say two conditional branches have 50/50 chance which does not benefit from branch prediction. Them merging the code wit

You're not a VIM's hostage. You're just following a very natural way of navigation--it's very easy to learn and you don't easily forget it. A very different story is using some other shortcuts like "F5" fo

Just ask the man two questions: Would you like to give heroin to your children, relatives, and colleagues. Would you like to pay for them if they don't have the money to get enough doses in their life? Many "leaders" I know t

You're never too old. It's just the new tools are not good enough.

I don't use vscode but I just upvoted. Hope it's speed/UX can be made comparable to vim.

Just took a quick peek at the binary-trees C code. Why using openmp while the others don't? why use recursive functions? The C implementation is not correctly optimized. People just paid more attention to Rust and other languages. Rust

More or less, the "top" universities have maintained an ecosystem that attracts so many people over the course of their live and makes people believe that's the "road" to a better life. The problem is not about the

I'm so eager to know how will people start to think of some bundled call phone plans such as a T-Mobile's family plan that I used for a couple of years. The Netflix subscription is offered "for free" with a "1? doll

I wrote my first line of code on a game console without persistent storage. Coding is everything that makes computer a computer. Now, some kids in college have an impression that coding is less relevant for a CS career.

This is so far the most exciting news I have seen since January. Would it help achieve herd immunity without having any vaccine? In other words, let the "vaccine" spread as fast as possible so more lives can be saved.

It was open to anyone years ago, but changed to this way as it gained attention from gov. It's very unlikely to see it going backward.

In this paper we introduce a new ordered index structure, named Wormhole, that takes O(log L) worst-case time for looking up a key with a length of L.
