seri4lon Netflix loses 1M users in Spain over password policing

I always thought these types of services didn't go after account sharing as a form of flexible pricing. The users who are OK paying $10/mo pay that. The users who wouldn't pay $10 share an account and get a slightly less convenient service.

Are their profit margins so tight that a 1:2 paying non-paying user loss ratio is a net win?

seri4lon Moths are more efficient pollinators than bees: new research

>if you see a honey bee in your back yard, there's a pretty good chance that somebody owns it.

This is true even in Europe. If memory serves the percentage of "wild" honeybees (feral may be a more fitting adjective) is in the order of 1%.

Add French to the list (unlocking the rest of Africa) and you have the 6 official languages of the United Nations.

seri4lon Why Did Thomas Harriot Invent Binary?

For some reason we had something like common core math in my elementary school in the early 2000s and I just had a traumatic flashback. Teacher forced us do EVERY sum like this:

17890 + 456 = 1 x 10000 + 7 x 1000 + 8 x 100 + 7 x 10 + 0 x 1 + 4 x 100 + 5 x 10 + 6 x 1 = 1 x 10000 + 7 x 1000 + (8 + 4) x 100 + (9 + 5) x 10 + (0 + 6) x 1 = 1 x 10000 + 7 x 1000 + 12 x 100 + 14 x 10 + 0 x 1 = 10000 + 7000 + 1200 + 140 + 6 = 10000 + 7000 + 1 x 1000 + 2 x 100 + 1 x 100 + 4 x 10 + 6 = 10000 + 7000 + 1000 + 200 + 100 + 40 + 6 = 10000 + 8000 + 300 + 40 + 6 = 18346

We had to write down everything and weren't allowed to skip ANY step, let alone write down the answer directly. Being taught sums and multiplications graphically is cool, I guess, but this was outright psychological torture.

seri4lon How Big Is Mexico?

The distortion is not because the Earth is 3D and maps are 2D, it's because the surface of the Earth isn't Euclidean like a plane is.

That means the meridians (the vertical lines you see on a map) which are perpendicular to the parallels (the horizontal lines on the map) intersect themselves at the poles (!). You can easily see how this leads to distortion of the areas closer to the poles (like Europe) on any projection where the meridians are parallel. Projections like Mercator account for this distortion by making the distances between the parallels bigger as one moves towards the poles. That's what makes Europe and Greenland huge, but more importantly makes it possible that any arbitrary straight line on a Mercator map corresponds to a straight line on the globe, which was huge for navigation.

seri4lon How Big Is Mexico?

The US has been a rich democracy for its entire existence and its homicide rate is on level with those of third world countries. I don't see how bringing a country that has been enduring constant poverty, unrest and revolutions into the equation will make anything better regarding violence.

seri4lon Is RAM wiped before use in another LXC container?

Apparently there's a kernel config flag to zero the memory on free (CONFIG_INIT_ON_FREE_DEFAULT_ON) but it has a quite expensive performance cost (3-5% according to the docs). I wonder in what kind of scenario it would make sense to enable it.

seri4lon Comprehensive Keyboard Handling in Terminals

You can configure a key combination to run a pager on the last command output, color and everything. You can also configure it so that it pipes the output of a command to a pager automatically whenever it is more than a screen long.

seri4lon Maps show how parking lots “eat” U.S. cities

When you live in front of a tall building that blocks the Sun the days are shorter and it's harder to keep the house warm during the Winter. Maybe I went too far calling it a "scarce resource" but tall buildings that are too close to each other increase the lighting and heating costs a great deal.

seri4lon Maps show how parking lots “eat” U.S. cities

Looking on the bright side all that open space means there is more sunlight, a scarce resource in many cities.

seri4lon We updated our RSA SSH host key

>And active key zeroation if it thinks you're trying to drill through the epoxy surrounding the crypto boundary.

Or passive! Probably it wasn't a real product but I recall reading about one that derived its key from the field generated by randomly arranged magnetic particles in the resin, or something like that. The point was to make it impossible to disturb the resin without altering the key.

seri4lon Instagram Is Disabling Its NFT Features

If it were up to me every person with access to a computer where other people's personal or financial data is handled should be required to get a security certification stating they have a basic understanding of digital signatures, certificates, HTTPS, encryption and how to protect against common threats (phishing, social engineering). If people can't do that they might as well go back to typewriters and FAX machines.

seri4lon Mexico cracks down on solar geoengineering

Since our society is unable to perform any activity without descending into an uncontrolled positive feedback cycle, I would rather none of us work towards cooling the Earth.

seri4lon How to Surrender to a Drone

That repost is missing a critical piece of information from the original article [1]. The drone in question is an unarmed aerial vehicle sent to a meeting place when a Russian soldier calls the "I want to live" surrender hotline. It isn't a protocol to surrender to an armed drone.

seri4lon How is crypto/blockchain %100 not beneficial if it makes Sci-Hub libgen funded?

>The "beneficial" property you're referring to is "can be easily used to fund criminal behavior", which is typically not a desirable feature in a payment system.

It typically is. The alternative is a system where a central authority has absolute control over all monetary transactions, which is definitely not desirable.

seri4lon “Judas goats” were once key players in meatpacking plants

Although they probably don't employ nicotine anymore using trained animals to guide sheep to a slaughterhouse is not a thing of the past. Another comment mentions Temple Grandin.

seri4lon BugMeNot Is Gone?

I created several BugMeNot accounts over the years without any issues. I guess if any of them got used for unsavory stuff it would be pretty clear from the logs that the account was shared.

seri4lon Overfitting and the strong version of Goodhart’s law

The issue with JIT is not so much about proxies as it's about optimizing for the general case at the cost of worst case performance. Things that suppose an inefficiency 99.99% of the time can be an indispensable redundancy or buffer in the face of events that are difficult or impossible to account for.

seri4lon Should we let cars use the road as a projection screen?

Humans also rely on visual information for driving and can easily be tricked. For instance, I don't think there is any security mechanism to prevent the placement of a battery powered green light on top of a red traffic light. In that case, an autonomous car's logs could actually help in discovering the tampering.

seri4lon Auditory brainstem response distinguishes occasional and constant tinnitus

I'm not a physician or neurologist, but I read a lot about this when I started suffering from tinnitus. There are indeed multiple types.

- Hearing loss related: the tiny hairs in the inner ear that transform vibrations into chemo-electric signals get damaged and start sending the wrong signal.

- Cardiovascular: a pulsatile rumbling that varies with heart rate. It's the sound of the blood flowing through some artery near the inner ear. I remember reading that it was caused by loud arteries and that it could be detected with very sensitive microphones.

- TMJ/cervical/postural: I think this one was about motor system or pain signals leaking to the ear circuit, but I'm not sure.

- Timpani related: wax buildup, tensor muscle acting funny...

This rough classification only deals with the "input" part, though. It doesn't explain how these bad inputs reach conscious hearing, causing distress. As a general rule, over time extreme pain becomes just pain, torrid heat becomes just heat, blue and red can be seen as white depending on the lighting conditions, even hunger and thirst are modulated by the nervous system. Eventually one learns to cope with tinnitus, but it's kind of fishy that this isn't filtered upstream by the auditory system, before it reaches conscious hearing.

seri4lon Unofficial guide to dotfiles on GitHub

Yeah, the git command traverses up the filesystem until it finds a ./.git/HEAD file or until it reaches /, whatever happens first. The problem comes when a 3rd program uses git to find the root of a project that doesn't exist and instead of failing finds ~/.git and naively decides to index everything under ~/. I don't know of any specific IDEs that do that, although I vaguely remember running into a similar issue in the past, maybe not with an IDE, which is probably why I do it that way.

seri4lon Unofficial guide to dotfiles on GitHub

One potential drawback of doing that is that every directory under ~/ that is not itself part of another git repository becomes part of that git repository, which could make some programs act weird, particularly project auto-detectors in IDEs and such.

To avoid that, one can rename the `.git` folder, effectively disabling auto-discovery, and run git with the option `--git-dir=<newname>`.

seri4lon Weird monitor bugs people sent me in the last 5 years

Something I learned not long ago on this site: low quality/too long HDMI cables can make some monitors go black when the user stands or sits on a certain kind of office chair. [1] [2]

Apparently it's a known issue at Dell: [3]

>Surprisingly, we have also seen this issue connected to gas lift office chairs. When people stand or sit on gas lift chairs, they can generate an EMI spike which is picked up on the video cables, causing a loss of sync. If you have users complaining about displays randomly flickering it could actually be connected to people sitting on gas lift chairs. Again swapping video cables, especially for ones with magnetic ferrite ring on the cable, can eliminate this problem. There is even a white paper about this issue.
