I hear you, but I'm suggesting a preconfigured one like the others that are linked here.

Maybe I'm overlooking, but would love if this had an accurate political globe (e.g., countries and capitals) for my young kids.

I was confused a few weeks ago. Check out the go pkg: https://pkg.go.dev/modernc.org/sqlite

1. gitlab.com/cznic/sqlite is the primary repo

2. github.com/cznic/sqlite was the github mirror but it moved

3. github.com/mordernc-org/sqlite is the read-only mirror of the primary repo

Cheers!

Good question. Indeed, I prioritized improving my vitamin levels for health reasons, including the possibility that it may reduce my headaches, rather than running a purely scientific experiment. If the migraines come back while I maintain normal vitamin levels, I'll continue my experimentation!

Back in August of 2021 I started tracking my headaches. I was experiencing 10+ debilitating migraines a month and had modified a number of variables in effort to reduce them (sleep, stress, water/caffeine intake, etc).

In September I got a blood panel from my GP and noticed low levels of essential vitamins. In October, I had 12 migraines. I started supplements for B12, Vitamin D, Vitamin K, etc. The migraines decreased each month: in November to 9, then 3, then 1. In February I had my first migraine free month in years.

Neurology is complicated. Migraines/headaches can be caused by a variety of factors. I chose to rule out things in my control (diet, exercise, stress, sleep, and finally vitamins) before taking daily use migraine medicine.

I'm working on the next version of JS8Call[1], a digital mode for amateur radio, that enhances the mode by using some of the latest RF research (LTE/5GNR/Turbo Codes/Polar Coding) for sending reliable messages over weak signals/links.

You will not usually have nor do you need line of sight for HF radio. The radio waves are reflected by the ionosphere at various angles and heights, allowing the signal to be received at many different distances at once. Radio waves at the correct frequency hit the ionosphere like stones skipping along the surface of water.

Yea, Metcalfe's Law at work. Give 40m a try.

This is not my proposal, but I think this is one that I like most with regards to Go and metaprogramming/generics.

Curious on the 40 minutes here. Why'd it take so long to recover?

New comment by jsherer in "An LSM-Tree-based Ultra-Large Key-Value Store for Small Data [pdf]"

jsherer — Mon, 02 May 2016 13:38:30 +0000

This looks like an interesting finding. Unfortunately, the trade-off for this type of efficient small data storage is real:

> Note that LSM-trie uses hash functions to organize its data and accordingly does not support range search.

Range search, while not directly applicable to all data sets, is an important feature of the LSM data stores compared (LevelDB & RocksDB).

The authors acknowledge this and say:

> There are techniques available to support the command by maintaining an index above these hash-based stores

So, don't plan on using an LSM-Trie for a direct replacement for your LevelDB or other LSM-Tree based projects that rely on Range searches without considering the additional complexity of building and maintaining an index to perform those Range searches.
