ujikoluk··on A visual proof that a^2 – b^2 = (a + b)(a – b)
That seems to show that there exist a and b such that the equality holds. But not that it holds for all a and b.
ujikoluk··on Why do animals adopt?
It is though, at the group level. The groups that adopt will have better survival than groups that don't, if the environment is such that parents regularly die while the cubs are small.
ujikoluk··on Attacking the hashing function in Tony Hawk's Pro Skater 2
Very cool article, love these.

> This brute force approach would work for short codes, but not for long ones. To generate all of the length 10 sequences would require computing about a billion hashes (8^10). That would work on my laptop, but length 11 codes (8 billion hashes) would be take a while, and 12 (68 billion hashes) would be a stretch.

We live in the future though. 68 billion hashes is absolutely possible on a laptop.

Would be very interested in trying an English-to-English mode to wash away my ESL accent.
ujikoluk··on I designed my website to look like a chat log
Love the design. Also love the attitude, wish we had more clear communication like this.

Would absolutely use this service if I was in need of a logo.

ujikoluk··on How Japanese black companies oppress workers (2014)
I don't think building an island is the answer. It will make it even difficult to integrate into the culture. And if you don't want to integrate into the culture, why are you there in the first place?

Maybe we should just avoid trying to classify things as good or bad.

Oh neat! Yes that's the kind of imagine I want to see
ujikoluk··on Show HN: RF Hunter – Find hidden cameras and other devices
I have long dreamt about building a portable phased array for this purpose, but additionally using the phase difference between receivers to visualize where the transmission source is.

In effect a camera into the RF world!

ujikoluk··on Solving the Mystery of ARM7TDMI Multiply Carry Flag
> Seriously, they decided that the program counter should be a general purpose register. Why???

Don't really understand this reaction. Why not? Seems to make for a nice regular design that the PC is just another register.

Did you get faster with time?

For prior art in this field, see:

"pingfs is a filesystem where the data is stored only in the Internet itself, as ICMP Echo packets (pings) travelling from you to remote servers and back again."

Also https://en.wikipedia.org/wiki/Delay-line_memory

Storing data as acoustic waves gave a higher capacity in practice, as propagation is slower thus fitting a larger number of symbol per time unit.

Yes, dimension reduction.

Explain more for the uninitiated please.

Hi I wonder how valuable patents are for EB/O visas? I have worked 10+ in a global tech company, through which I am named on about 20 US patents. I don't have external visibility except for through those patents. How are patents judged when it comes to these visas? Are they enough to prove what needs to be proven?
