An OTDR sends pulses of laser light into a fiber optic cable and records the minute reflections that occur at every point of the cable over time. The time of arrival of the reflections corresponds to the position of where it was reflected. This way you can record the attenuation of an entire cable just from shining in pulses from one end. Good for checking if a new cable was properly installed, or for finding the location of issues in existing cables for debugging.

Recently a supplier of ours announced that we could finally host their shitty java app on Linux instead of paying fucking Oracle for Solaris. So we were eager to hear the requirements. It was RHEL 8.4 or something, a version that was already EOL at the time.

They can't even update their distros apparently.

Those two, Lindsey Ellis and Philosophy Tube are the only four that I found good. It's kind of thin still.

Category: OTDR measurement results
File extension: .xml or something entirely new

OTDR: Optical Time Domain Reflectometry
SOR: Standard OTDR Record
XML: Extensible Markup Language

.sor files are a mess, poorly standardized, too restrictive as a format, and every manufacturer makes their own proprietary extensions.

An omnidirectional mic 20 cm downwards from the persons mouth is supposed to sound better than a little boom mic right in front of them? That's not very convincing.

OTDR measurement results in like XML or whatever open self documenting format, just not SOR. Or even just in actual standards compliant SOR, if that's all I can get.

They spell the correct relationship out clearly in the article:

Advance Publications, which owns Ars Technica parent Condé Nast, is the largest shareholder in Reddit.

Oh that's interesting, thanks.

Do you know what they did before they took Crimea in 2014? Maybe there is old infra they can reactivate somewhere?

Edit: Nevermind that question I see there is a more complicated history behind this: https://en.wikipedia.org/wiki/Partition_Treaty_on_the_Status_and_Conditions_of_the_Black_Sea_Fleet

Isn't it a bit extreme to assume that the black sea fleet would leave the black sea?

Am I missing something here? Was Sevastopol the only harbor Russia had on the black sea?

I tried that but it didn't get me around it, I don't remember if the site just didn't respect the browser request or if it was unnavigable...

Swiss Post did that too, you used to be able to buy "stamps" (well codes you would write on the envelope serving the same function as stamps) over plain old SMS. They they stopped that since they have that new whatever service. That service works on a PC browser, but on the phone browser the function is not available, no there you need the app. For fucking no reason at all.
