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 …

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 …

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 featu…

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 …

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 thou…

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…

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 r…

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 ben…

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 oth…

The time axis is incomplete. It's just 5 years "without problem".

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…

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 jus…

The programmer is often more important than the PL.

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 …

You will find gems just by checking the third-party cookies associated to those websites. I can see cookies from dexdem.net, doubleclick.net, and facebook.com on my chase.com accou…

Indeed. It was like "I'm going to make them an offer they can't accept."

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…

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 c…
