According to statistics I recently heard, you'd be twice as likely to have a successful exit if you were 50 than 30 when founding, but you'd also find getting investment more difficult because investors prefer younger founders. (

There's already a notable new variant circulating. It's called Omicron BA.2, sometimes "Stealth Omicron" because it is not as easily identified as Omicron BA.1. Looking at the UK figures, although there was a Jan/F

For me, it was the discovery that most of my browser slowness was due to TST, and Sidebery didn't have that problem. Probably only a problem for people with lots of tabs.

What, if anything, is preventing for-profit platform co-ops from obtaining VC money and chasing a similar growth-to-unicorn curve? Is it just cultural inertia, i.e. nobody has tried yet?

I would not call it simple for all refugees. First, even citizens can find it challenging to join a challenger bank. Some UK citizens don't have the types of documentation those banks require. I once spoke with customer service of on

In pure functional programs it's possible to copy the state (monad/environment/free variables), but it's not always efficient, depending on what those are. In general programs, doesn't have to be functional, the env

In my tests, for NVMe storage I/O I found io_uring was slower than a well-optimised userspace thread pool. Perhaps the newer kernel is faster, or there is some subtlety in the io_uring queueing parameters that I need to tune better.

It's not, because in a standard B-tree all the leaf nodes are at exactly the same depth, whereas in a binary tree they are not in general, unless the binary tree is balanced with exactly 2N leaves. This difference occurs because a B-tr
