zaxomi··on A love letter to the CSV format
There are better separators included in ASCII, but not used as often: 28 File Separator, 29 Group Separator, 30 Record Separator and 31 Unit Separator.
zaxomi··on Why does target="_blank" have an underscore in front?
>> It’s a shame they were deprecated without a modern replacement.

Isn't iframe the replacement? iframe is not deprecated.

zaxomi··on Das Blinkenlights
I'm planning to do something similar, but using addressable RGB LEDs (like WS2811, also known as neopixel).

They are simple to work with. Each LED has 4 connections: GND, +5V, DATA IN and DATA OUT. Each LED grabs the first 24 bits of the data stream (8 bits for Red, Green and Blue) and sends the rest on DATA OUT for the next LED.

zaxomi··on Decoding the telephony signals in Pink Floyd's 'The Wall'
There are few well-documented standards. There are ready-made solutions that have worked for decades. What do you think AI would add?
zaxomi··on ASCII Delimited Text – Not CSV or Tab Delimited Text

zaxomi··on Show HN: I built an app to use a QR code as my doorbell
I wish my annoying neighbor would get this, because then I can post the code online and have the whole world knocking on his door at all hours of the day.
zaxomi··on Standardizing Automotive Connectivity
The phantom power at 48 volts used with XLR connectors only have a current at about 10 milliampere. Enough to supply power to a little microphone.

The connector is bulky and of metal, and designed to be used inside. It's also expensive compared to other connectors. There are a lot of cheaper, more suitable connectors, designed to carry power.

zaxomi··on Standardizing Automotive Connectivity
Depending on the country you live in, the laws might allow you to do work on equipment that is below 50 volts, but require you to be a certified electrician for anything above that.
zaxomi··on JSON Patch
> appending things to arrays etc can't be done elegantly

Are you referring to the possibility to point to the end of the array? If so, a single minus sign might solve it: "/path/to/the/array/-"

RFC 6901 JavaScript Object Notation (JSON) Pointer > exactly the single character "-", making the new referenced value the (nonexistent) member after the last array element

zaxomi··on Final two communications from MH370 support controlled descent scenario (2021)
All vehicles that can be steered have that possibility, even cars: If there is a steering wheel, it is possible to deliberately crash the vehicle. If it is possible to shut down engines, it can also be used for malicious purposes. In other words, there is always the possibility of using everything for malicious purposes.

On the other hand, the ability to shut down a system that has failed can save everyone on board.

There are approximately 40,000,000 flights each year. Almost all occur without incident. In the entire 120-year history of aviation, only a few accidents have resulted from the pilot intentionally crashing the plane.

zaxomi··on Postgres feature you're not using – CTEs a.k.a. WITH clauses
A quick search shows it in the documentation for version 8.4, released July 1, 2009.

Maybe 15 years is "somewhat recent feature". :)

zaxomi··on The Elegance of the ASCII Table
Remember that ASCII is short for "American Standard Code for Information Interchange".

base64 was proposed in 1987 to work with ASCII, EBCDIC, and other character encodings.

zaxomi··on Thinking out loud about 2nd-gen email
I can't register an account at discord, negate I'm behind CGNAT and someone else in the region was banned by discord.
zaxomi··on Protecting your email address via SVG instead of JavaScript
Cool.

zaxomi··on Regex character "$" doesn't mean "end-of-string"
Still doesn't support internationalized domain names.
zaxomi··on Regex character "$" doesn't mean "end-of-string"
Remember to first punycode the domain part of an email address before trying to validate it, or it will not work with internationalized domain names.

Every change breaks someone's workflow: https://xkcd.com/1172/
zaxomi··on Bit banging a 3.5" floppy drive
The first floppy from 1967 only had one side. Adding one signal to select side was an easy solution to increase the capacity without to much modification of the controller. Adding the capability to read from both heads at the same time would require much more modifications, and more memory.
zaxomi··on YouTuber pilot regrets intentionally crashing plane, gets 6 months in prison
I think his only regret is that he got caught.
zaxomi··on Can a Passenger Hack an Airplane?
Coordinating Committee for Multilateral Export Controls (COCOM) limits is 1,000 knots (510 m/s) and/or at an altitude higher than 18,000 m (59,000 feet).

Commercial airliners usually have a service ceiling at about 40000 feet and a speed below the speed of sound (343 m/s). Even with a very strong jet stream of 100 m/s it's below the limit.

The Concorde had a service ceiling of 60000 feet and maximum speed of 605 m/s.

zaxomi··on EU Parliament Civil Liberties Committee adopts position on CSAR
Wow, EU Parliament did the right thing this time.

When I heard an interview with a Swedish EU politician, I thought it was a lost cause. She was completely blinded by the possibilities and saw no downside whatsoever.

No matter what language they choose, someone will complain and ask "why X, why not Y or Z?"
zaxomi··on Safari share menu now violates privacy
It's getting the favicon, and while doing so gives information about the client in the user-agent and the IP-address.

How is this different from any other request to a website?

zaxomi··on Advice to a novice programmer
Some of the things I use in vim:

* Mark a position in the file, so I easily can jump back.

* Quick recording of a macro that to do the same type of edit multiple times (very handy when refactoring)

* regular expression search and replace, very easy to limit the scope.

* Easy to select, copy and paste lines or columns.

Everything without touching a mouse.

zaxomi··on Google settles account settings lawsuit less than one week after being filed [pdf]
When they sent out the directive to remove "Don't Be Evil" someone was too lazy and just removed "Don't", so ever since then it's been "Be Evil".

That explains a lot, doesn't it?
