Just curious. How does that work on changes between depending states within a cycle? E.g. [foo, setFoo] = useState(1); [bar, setBar] = useState(); setFoo(10); setBar(foo * 2); // Is bar 2 or 20 at this point?

How do you connect your VPN with your phone when you travel on the road?

I’m using an internal machine for the VPN server and port forwarded to it from the router. I also have Tailscale set up but if I remember correctly Tailscale requires all devices participating in its VPN to install its software, which is to

Setting up a dynamic DNS record to map a hostname to my home network’s dynamic IP actually makes private VPN usable. It’s really a game changer to be able to access all the local services and resources on the road without exposing them to

I assume the fourth point is for billing clients for a high fee while paying a quarter to the associates. But some law firms will use the more efficient tools to take on more cases for the partners to bill on their higher rates. Competition

For "write everything twice" I would say write some parts many times. You don't have to write everything twice. Most code are optimal or good enough already, but you should be willing to re-write some parts over and over ag

I found WSL2 to have similar performance to native Windows. The only slowdown is loading files from the Windows side via /mnt/ which goes across the VM boundary. Move the files to the Linux side and it’s good.

Thanks for the wonderful article. I’ve tried running models locally. I found that collocating the models on my computer/laptp took up too much resource to impact my work. My solution is to run the models on my home servers since they c

Yes. Swiss is good for non-duplicate lookups. For highly duplicate data the extra memory fetch for the metadata byte really kills the performance. For this contest, there’re a billion lookups with only couple hundreds distinct keys. That me

Ha. I didn’t know the detail of any of these tables beforehand. It’s just a matter of doing a bit of research. The main takeaway is there’s no perfect hash table. It all depends on the data and the operations. Contests like this are the per

Besides the standard tricks to speed up the running time like threads and mmap, the biggest speed up is to use a custom hash table that is tuned for the data. I have implemented 5 different versions of hash tables including the Swiss hash t

That’s the -F option to list all the formats, including the audio streams. Pick the audio format with -f to download the audio. I usually pick the .m4a format and then run it through ffmpeg to convert to mp3.

Use KeePass and its variants, for storing the encrypted data in a local file. Use any of the file sync products to sync the file across devices, e.g. Dropbox, Syncthing, etc.
