It should've stopped there :D

lmc··on Time-Series Anomaly Detection: A Decade Review
It would be useful to see some discussion of sampling regularity, e.g., whether some of these methods can be used with unevenly spaced time series. I work with satellite image time series, and clouds mean my usually-weekly series can sometimes be missing points for months. We often employ interpolation, but that can be a major source of error.

Interesting ideas. If you do some subsequent post on this, it would be great to see how the perf benefits scale with different sizes of AoIs.

Is anyone using this in a team? How is the perf?

There already are some established ones, e.g., https://www.ogc.org/standard/wfs/

It's widely used in the GIS field, but unfortunately not adopted by the most popular consumer apps.

lmc··on Null Island is one of the most visited places on Earth, and it doesn’t exist
Welcome to GIS :D

Seriously, it's a domain with huge under-the-surface complexity (no pun intended)[1], and most of the early efforts were spent in dealing with the maths and science, rather than software engineering. Things are getting better though.

[1] here is a good jumping off point (imagine the technical debt this might lead to): https://en.wikipedia.org/wiki/Spatial_reference_system

lmc··on Strong Consistency with Raft and SQLite
Great, that is good to know! Perhaps a little about this on the site could be helpful for others.
lmc··on Strong Consistency with Raft and SQLite
Marco, you're probably going to want to rethink your branding. It sounds like you're associated SQLite officially, when AFAIK this isn't the case (?)

The code is open source, but the name is a registered trademark. Similar issue here: https://github.com/vapor/sqlite-kit/issues/47

lmc··on ChatGPT: How many letters has the string “djsjcnnrjfkalcr”?
Haha, okay, yes :-)
lmc··on ChatGPT: How many letters has the string “djsjcnnrjfkalcr”?

    Me: How many characters are in the string "sdfyskkgagag"?

    ChatGPT: The string "sdfyskkgagag" has 14 characters.

    Me: That is incorrect, please try again

    ChatGPT: I apologize for the mistake. The string "sdfyskkgagag" has 12 characters.
To me, that sounds like it has some understanding. Fallible and weird, but it's there.

Actually, i was agreeing with the GP, so it's at least 2 v 1 ;-)

It really isn't. I did all that as a kid and still get hopelessly lost. Source: Experienced hiker, backpacker and mountain runner, over several continents.

lmc··on [Fedora-legal-list] Change in classification of CC0
Yes, my cliché detector kicked in hard when I wrote it :-)
lmc··on [Fedora-legal-list] Change in classification of CC0
So what they are worried about is an entity that does the following:

1. Quietly patent sexy new algorithm

2. Release CC0 implementation of algorithm without mentioning they hold a patent.

3. ? (sue for infringement)

4. Profit

Anyone that tried this should be laughed out of court. If they're not, the law needs an overhaul.

lmc··on My Poor Experience With Azure (or why I'm sticking with AWS)

That is literally the Azure home page.

My favourite moment of corporate dystopia was during my first job after finishing my undergrad...

December 18th, they asked us to put up a Christmas tree.

To ensure an efficient return after the Christmas break, they made us take the tree down on December 23rd. :-)

Thanks for your response. I have no affiliation, it just piqued my interest.

> I must also admit, that I like my simple approach of just keeping data in compressed local files. With fast SSDs it is super easy to scale and fault tolerant. Nodes can just `rsync` data to keep up to date.

I also like this approach :-)

Interesting. Have you come across TileDB before?
