amatix··on Nurdle Patrol
There's a similar UK initiative which has spread to a number of other countries.

Nurdles are everywhere... https://www.nurdlehunt.org.uk/nurdle-finds.html

amatix··on How Lego builds a new Lego set
Even today the LEGO-compatible knock-offs are complete junk, my kids occasionally end up picking up a loose bag for £1 from the local charity shop. Pieces don't stick together properly (with each other, let alone LEGO pieces); legs, arms, and hands come off the minifigs; etc. You can instantly tell — even ignoring the assault rifles that would never make it in a LEGO box.
amatix··on Spotify will reduce total headcount by approximately 17%
> Spotify reported that it had 9,400 employees at the end of the third quarter of 2023. It had already cut back employee numbers by 6% in January and by a further 2% in June.
amatix··on Portugal just ran on 100% renewables for six days in a row
There's a company working to build a 3600km long cable between solar + wind farms in Morocco, and the UK. 3.6GW cable, 10GW of generation, 20GW of battery storage, and the cable should run at full load for 20h a day.

amatix··on Kart: DVC for geospatial and tabular data. Git for GIS
Good questions

> Are the raw files in the working repository GeoPackages?

The working copy for a vector/table dataset can be in a GeoPackage or a SQL database like PostGIS. For rasters/point-clouds they're flat files.

> How is it tracking the changes made inside the geopackages?

In general, triggers which store RowIDs/PKs of inserts/updates/deletes. Then when you ask for a diff or make a commit Kart figures out any actual row-level (or schema) differences.

> What happens if it's replaced with an updated copy of the geopackage the was edited via some other application?

If it's edited by something else (QGIS, ArcGIS, python/go/whatever application, SQL CLI, whatever) it'll work: you do edits where you want to. If it's replaced by something else, it won't work.

> How does it diff the changes?

Comparing the features/rows in the repository (and their schemas) against the rows in the working copy database. It uses the stored list of modified rowids to make this fast.

amatix··on Air-to-Air Heat Exchangers for Healthier Energy-Efficient Homes
The BluMartin FreshAir 100 and the Fresh-R series are both MVHR units that fit into existing walls: there’s a Fresh-R model that goes into a window frame too.
amatix··on 'A fluke': The oldest webcam is still watching over San Francisco
Different brands vary, but IME this is only correct for a few weeks at best. Otherwise you'll get a lot of residue, and if it's been outside exposed to UV you'll get even more. And duck tape is worse.
amatix··on DC3 Still Flying at 70
Air Chathams has a DC3 in their fleet, there’s a great Allplane podcast episode (incl transcript) on some of the other old planes they fly and how their operation has evolved.

amatix··on For Tesla, Facebook and Others, AI’s Flaws Are Getting Harder to Ignore
And at the same time, the UK government is looking at reversing the GDPR review right for automated decisions:

Article 22 guarantees that people can seek a human review of an algorithmic decision, such as an online decision to award a loan, or a recruitment aptitude test that uses algorithms to automatically filter candidates.

In May, a government task force set up to look for deregulatory dividends from Brexit, led by the leading Brexiter Iain Duncan Smith, argued that Article 22 should be removed because it made it “burdensome, costly and impractical” for organisations to use AI to automate routine processes.

The idea is part of broad-based plans for a big overhaul of the UK data regime after Brexit which ministers say will boost innovation, and deliver what Oliver Dowden, the culture secretary, has called a “data dividend” for the UK economy.

amatix··on Support for team members who are mistreated in their country
I'd argue the official spec is now https://commonmark.org/ - it was partially reversed from the actual implementations in use and their behaviours, and is very highly specific compared to the original guide.
amatix··on macOS extensions are moving away from the kernel
TripMode (https://tripmode.ch/) for filtering application Internet access when you're running on mobile data uses a kernel extension.

Tesco and ASDA have both been delivering to anyone throughout, and Sainsbury’s has opened out to anyone in the last week or so.
amatix··on Microsoft’s quest to go ‘carbon negative’ inspires $1B fund
Depends on the VAT system. In New Zealand you can almost count the VAT (GST) exceptions on one hand (most land/property, bank charges, and goods/services that are exported), everything else supplied domestically has one flat rate of 15%.

Compare this to the UK, where there's massive sets of exclusions and several different rates in force. Takeaway vs dine-in food, digital vs physical books, ... a total mess.

amatix··on HTML attributes to improve your users' two factor authentication experience
Authy’s iOS app still doesn’t have an actions/app helper, so every time you need to switch to the home screen, find & launch it, search for the site, close the keyboard (the copy button is obscured by it), hit copy, then switch back to Safari/wherever and paste. So much friction.

Kind of implies the engineers who build it never ever use it?

amatix··on EU votes to create gigantic biometrics database
FYI, any non-British citizens living in the UK (excepting EU for now) are being forced towards getting Biometric Residence Permits with any visas/renewals... a plastic card containing photos/biometrics and a big ID number on it. And biometrics are collected every time you cross the border.

amatix··on Prototype to production: How to build and design a PCB prototype
I have a small prototype I need to get from a schematic stage (needs additional checking & decoupling caps, etc added) to a few PCBs - I was thinking of hiring someone to do the PCB layout. forum.eevblog.com was mentioned above, there are hardware designers on upwork - anywhere else I should look?

Seems to be using the `Server-Timing` header — are there docs somewhere on what this expects & what features it supports? Are other browsers likely to follow it?
amatix··on Termination of StartCom business
Received an email too:

Dear customer,

As you are surely aware, the browser makers distrusted StartCom around a year ago and therefore all the end entity certificates newly issued by StartCom are not trusted by default in browsers.

The browsers imposed some conditions in order for the certificates to be re-accepted. While StartCom believes that these conditions have been met, it appears there are still certain difficulties forthcoming. Considering this situation, the owners of StartCom have decided to terminate the company as a Certification Authority as mentioned in Startcom´s website.

StartCom will stop issuing new certificates starting from January 1st, 2018 and will provide only CRL and OCSP services for two more years.

StartCom would like to thank you for your support during this difficult time.

StartCom is contacting some other CAs to provide you with the certificates needed. In case you don´t want us to provide you an alternative, please, contact us at certmaster@startcomca.com

Please let us know if you need any further assistance with the transition process. We deeply apologize for any inconveniences that this may cause.
