That's not gonna work for real-world projects. Real-world apps often have larger edits than locking individual cells/cards e.g. Move columns or replace large chunks of spreadsheets in Google Sheets, or Ctrl-A to select all and then drag to move.
Also, if you consider latency, locking does not work well because client B might do operations before he/she even acknowledges the lock from client A because of latency.

It's a good thing to take care your own children. "Loses an estimated $122 billion a year" is like a weird attempt to makes it sounds bad.
The puzzle need to be solved is how to let people rejoin the workforce later without their career wrecked (with a discontinued CV).
namelosw commented on Tao Te Ching – Gia-Fu Feng, Jane English Translation (1989) terebess.hu/english/tao/g... · Posted by u/softwaredoug
I've seen Tao Te Ching's translation on the HN front page for several times. It seems people are interested in it.
The thing with Tao Te Ching is it's too ambiguous because: 1) The Chinese language is very overloaded and thus very ambiguous. 2) Classical Chinese is even more so. 3) Tao Te Ching is intentionally filled with clever puns which makes it more ambiguous.
The problem with translations is the translator has to interpret source texts into specific meanings in the target languages. It's like opening Schrödinger's cat box, or unwrapping monads in Haskell and Rust, which essentially deduct multiple possibilities into a single deterministic value.
If you're really into it, you probably want to learn some basic Chinese and classical Chinese (lucky they're not so different from each other), and figure out how to look up in the dictionaries. It's probably not as difficult as it sounds - all you need to do is decrypt with dictionaries.
Maybe there should be a new form of digital translation, just like hovering texts on Duolingo and it will display all the possible meanings of the word/expression.
namelosw commented on Ask HN: What are your 'mental hacks' to remember small tasks? · Posted by u/AlwaysNewb23
It's essentially creating states/variables then garbage collect it upon completing. There are several things you can do:
Remember it in your brain: It's like let the state occupying one of the 16 registers in your brain. Later it will automatically offloads in the hard disk in your brain but there's a chance it gets lost or cannot be recalled reliably. Not recommend. But I do this more recently because I realised I don't have to do everything.
The stateless approach: Do it immediately so you don't need to bear the state/variable. Even though sometime it disrupts my current tasks, I find this approach is surprisingly relieving - less debts. Just like software engineering - minimise states because they're evil.
External storage approach: Write it down on paper or an app. There are trade offs between the tool you're using, but the key is to minimise the cost of your moves.
For pen and paper I tried different configurations until I can always comfortably carry them in my pocket.
For digital approaches I'm currently shovel things to Linear. Make sure you're fluent with shortcuts so you can create tasks and jump around like a breeze. I also use Arc browser and pin it in the third slot so I can jump to Linear with <Cmd-3> without even thinking about it.
namelosw commented on Nvidia to Challenge Intel with Arm-Based Processors for PCs bloomberg.com/news/articl... · Posted by u/marc__1
It seems Nvidia was trying to unify cloud computing (GPU + CPU + whatever-PU), and put those beasts in data centres.
Is this "PC" processor still aiming for data centres or desktops? It's not surprising at all if it's the former one.
namelosw commented on How to run 50% faster without external energy (2020) science.org/doi/10.1126/s... · Posted by u/beefman
Their model seems to predict a theoretical top speed of 18-20.9m/s (or 40.0-46.8mph, 64.8-75.2kph): https://www.science.org/doi/10.1126/sciadv.aay1950#F2
As much as I want to imagine people chasing down cheetahs, without empirical testing I have to admit I am skeptical of their claims.
Wow that's fast. But it sounds dangerous.
The last time I attempted to run at full speed after not running for years, I struggled to keep up and lost my balance. I started tilting forward slowly and eventually fell then slide on the ground for a while, resulting in multiple scratches on my face, front pelvis, etc.
The demo at the top of the homepage (https://reflect.net/) is a lot of fun. While I was watching, every time the puzzle got completed, people would shake their cursor in excitement, like saying, "yay we did it!!"
Man, they nailed it with this page!
I somehow kept the habit of handwriting for years. But as a guy in my early 30s, I do notice characters fade away from my brain from time to time, which wasn't a thing at all in the 20s. And to my surprise, some of the characters are fairly frequently used - I was just completely stuck when I was trying to recall them.
Probably that's how brains and organs peaked and will slowly break down over the following decades just like hard drives.
