kozak··on ArVid: Russians squeezed 4 hard drives into one VHS tape in the 90s
Same for 40 kHz or 48 kHz or anything above, but there is (was) a specific reason why 44.1 got chosen.
kozak··on ArVid: Russians squeezed 4 hard drives into one VHS tape in the 90s
Fun fact: nowadays music is still distributed mostly in the 44.1 kHz sample rate, and this odd rate derives from how much it was comfortable to store on a PAL/NTSC video tape using devices similar to Technics SV-P100 (when video tapes were the only viable way to store full-quality digital audio). So this number is ultimately derived from line count and frame (field) rate of analog TV standards.
kozak··on Paper Sizes and Formats
A3+ is for getting your end result as an A3 sheet after you cut the edges.
kozak··on Battery Electric Vehicles: How Many Gears? A Technical-Economic Analysis
If we look at a (or the only?) popular multi-gear EV which is Porsche Taycan, it uses the upper gear for almost anything except for sport-mode launches (i.e. a very narrow use case).
kozak··on The Curious Case of MD5
I still use MD5 as a 128-bit checksum algorithm that is fast and universally supported and compatible everywhere. In this role it's still useful, just don't expect it to be a cryptographic hash anymore.
kozak··on LastPass will enforce a 12-character minimum master password
This is only about the master password. I assume it won't have any stupid requirements like "include at least one digit", and will instead assess the amount of entropy, allowing passphrases to be used.
kozak··on Ask HN: What are good books/blogs to read for a first time CTO?
If it's just a "planning my first startup" stage and not an existing enterprise of some non-zero size, I'd suggest starting from the book "The Lean Startup" by Eric Ries and other general "startup mentality" information sources. For a tech-minded CTO, it's especially important to have that correct "startup mentality" to avoid big mistakes from the start.
kozak··on USB-C Cures Mosquito Bites
Looks similar to piezo "clickers" that are supposed to help against mosquito bites. But is the working principle based on temporarily damaging nerve endings? If so, is there a potential for a long-term negative effect with active use?
kozak··on Polish trains lock up when serviced in third-party workshops
This is probably perfect for some EU anti-monopoly lawsuit, am I right?
kozak··on USB Power Delivery for Hobby Projects
So, why are center positive barrel jacks risky when used with rechargeable batteries? I tried googling and asking ChatGPT about that to no avail.
kozak··on Goodbye integers, hello UUIDv7
As someone who only cares about v4, I periodically wonder why don't I just use fully random 128-bit identifiers instead (without the version information).
kozak··on Goodbye integers, hello UUIDv7
Here in Ukraine trying to estimate enemy's drone and missile production capacities by serial numbers of their parts is quite a mundane task these days.
kozak··on Exxon says world set to fail 2°C global warming cap by 2050
Nationalization is not a guaranteed solution because of the dangers of populism.
kozak··on 111,111.1 meters is reliably 1 degree of latitude
Metric woodworking just uses integer millimeters for everything.
kozak··on How to drill your own water well
I suppose you use a gasoline water pump if you don't. Unless you are in a desert, of course.
kozak··on Tesla gives UK owners grabbing stick after forcing them to get left-hand-drive
Sounds like The Onion.
kozak··on NeXT Computers
Every modern macOS computer is a continuation of the NeXT lineage.
kozak··on Improved audio rendering with an optimised version of memcpy (2013)
Fun fact: vinyl has constant angular velocity, not constant linear velocity. It means that sound fidelity gets progressively worse while going from outer tracks to inner tracks.
kozak··on ‘I will show you how safe Telegram is’
For me personally, the main argument against Telegram is that its development and operations team is physically located in Russia. This means that they can very easily be bribed and/or intimidated into any type of collaboration with their state.
kozak··on International Security and Estonia 2023
It was the same in Ukraine as well (see Ukrainian-Soviet War of 1917–21), but there was more time to cover the traces and erase this from memory.
kozak··on Ask HN: Concepts that clicked only years after you first encountered them?
Entropy. Both in information and in thermodynamics, and how brilliantly they are connected. The audiobook "The Big Picture" by Sean Carroll has helped a lot.
kozak··on Airlines lobbying FAA to have only one pilot in the cockpit
It is also interesting that in that third incident it was the presence of a THIRD pilot in the cockpit that helped to diagnose the problem.
kozak··on High-documentation, low-meeting work culture
This is the first case I know of. I never get such issues here in central Ukraine. This is because occupied regions always present themselves as Russia, not Ukraine. If something says that it is Ukraine, it's a sure sign that it is NOT occupied by Rissua.
kozak··on High-documentation, low-meeting work culture
"Unfortunately, Tremendous is not available in the country where you are located. If this is a problem, please contact support@tremendous.com."

I'm in Ukraine and this is disgusting.

kozak··on Windows' Undocumented “Emergency Restart”
Equivalent of the old good double-press of Ctrl-Alt-Del that we used to have in Windows 9x?
kozak··on Webcams aren't good enough
Sad to see such an imperfect monitor mount type on a webcam that tries to be better. For better eye contact, lens should be as low as possible to be as closer to where you are looking as possible. This one doesn't seem to even try.
kozak··on I Had Ramen Every Day for a Week, Here's What Happened
Same for me.
kozak··on Largest airship built in United States since 1930s to take shape soon
As far as I understand, helium is a non-renewable fossil resource. So a sustainable airship design should be using hydrogen instead. The challenge is to make it safe.
kozak··on Tactical battlefield nuclear Weapons in Ukraine?
As a Ukrainian, I agree.
kozak··on Kaspersky is declared a US national security threat and is banned by the FCC
Telegram is next?
