Even worse, it's "deplatforming attempts". If someone complains about a speaker, even if the institution doesn't agree, it seemingly goes on the list. In that context it feels even more ridiculous.

It's not a commercial application, but I have 2 raspberry pis rack-mounted[i] running some utilities for my home network (pi hole, gps-based NTP, ads-b data for FlightAware). Using PoE means no USB power bricks, no USB cables running all over the rack, and one less thing I need to plug into my UPS.

I am slightly disappointed that this doesn't work in Firefox, despite the fact that I have an add-on[1] installed to add U2F support. Github for instance is able to detect U2F support and let me use it.
That said, I understand the lack of support since I am an extremely small niche, and this did prompt me to finally add 2FA to facebook (U2F and code generation from my Yubikey Neo)

The way that the author uses GPS to get time (NMEA messages) works well for the purposes of the article, eg syncing a wristwatch to ~1 second accuracy. As another poster pointed out though, these messages are only accurate to about a half-step one, and it is actually worse than just using an internet NTP signal.
If you want to build a GPS based NTP server, you need a GPS board that outputs a PPS signal. When I built mine I used an adafruit board hooked up to a raspberry Pi's GPIO pins.
It's something of a bear to get everything to play together properly and get the extremely precise PPS signal to the NTP server, I recall it required a custom kernel module and a lot of tinkering with tick rates.

quantum computers, at best, divide the bit-strength of a symmetric key like AES in half[1]. Brute forcing a 128 bit key is theoretically possible (in the sense that you can do it if you marshal the entire world energy output to the cause, you could crack 1 key/yr), but not a 5 minute process.

Bruce Schneier and others[1] have done the math on brute forcing 256 bit keys: even with a perfectly efficient computer using the least amount of energy possible, you would have to deplete the entire energy content of the Sun to just iterate over a 225 bit keyspace once, let alone do anything meaningful with those keys.
Moore's Law doesn't really factor into it.

In what is probably the biggest case, FlightAware, a lot of the data comes from a fleet of users running ADS-B[1] receivers feeding data into their system. ADS-B data is what Air Traffic Control uses to track planes, and it's receivable using using a cheap TV tuner and a raspberry pi[2]. It ends up being probably the best way to track planes very precisely, as long as you can get enough coverage, which flightaware manages to do pretty well [3]. They then package this data and sell it via an API/tools for Fixed Base Operators or apps like Just Landed.

Since a screenshot of the Just Landed app shows up in the image carousel on your link, I am assuming that they used FlightAware for their data. FlightAware charges people for API access, and also specifically provides a set of tools for FBOs (https://flightaware.com/commercial/fbotoolbox).

well, for one, the IRS doesn't treat bitcoin as a currency, but as a commodity. While some foreign currency transactions fall under the regime of capital gains, a transaction resulting in the gain/loss of less than $200 are specifically excluded from capital gains [1].
Note that this relates specifically to changes in value of the US currency in relation to the commodity or foreign currency. In this sense there is a difference between a sports car and a cup of coffee encoded in law. If the euro you bought for $1 is suddenly worth $1.02, and you buy a 1 euro coffee, you'll only realize $0.02 in gains, and not hit the $200 threshold. If you buy a 100,000 euro sports car, you will realize a $2000 gain, and have to report that on your taxes.
Since bitcoin is a commodity, it doesn't matter if the value moves 2 cents or 2 dollars or 2 million dollars, all gains are capital gains.
So if you buy a coffee with euros you specifically don't need to report that, but with bitcoin you do. Whether the IRS is going to notice that you don't record every single capital gain arising from a bitcoin transaction is another question, but there is a major difference between foreign currencies and bitcoin as far as the IRS goes.

> That's strange. In what industries? Doing what?
For one, Python is very big in the GIS space. Python is one of the main scripting language for ArcGIS, which is the main software platform that GIS folks use.

who says Kiro isn't using version control?
traditional web hosts provide a level of management that isn't present in VPSes. You may be able to get turnkey instances, but you still have to be responsible for managing them and maintaining them. Vs a traditional webhost where you don't have to worry about all that.
You can claim that its "outdated" and "akin to using tables for layout", but its also still a very valid workflow for a lot of people who don't want to be sysadmins in addition to developers

I did that with my first SSD system, mapped C:/Users to an separate HDD. Honestly it was more trouble than it was worth.
Using a junction point for a critical folder like that requires booting into a recovery mode and entering a bunch of incantations into a cmd window. And things will go sideways if you have to remove the Users drive at any point.
An easier course of action is to just use the Libraries functionality under windows and map each of those to write by default into your HDD. so most of my documents reside in D:\media\Documents instead of C:\Users\[blah]\Documents. Then you can also leverage the SSD speed for stuff in your AppData.
