sannee··on DRM for chargers? Google Pixel 3 locks fast Qi charging to its own stand
If you assume faulty charger, you have to figure out a way of dropping at least 5 extra watts of heat somewhere in your phone. That seems practically impossible without significantly compromising on mechanical properties of your device.

It's effectively biological version of fuckit.py [1]

sannee··on Ask HN: Where to go for the cheapest EE degree in the U.S.? In the World?
Basically, if you want a dorm here, you have to start reserving in May/June.
sannee··on Introduction to Differential Equations (2008)
Not really Computer Science per se, but practically every engineering field uses numerical solvers. No one reallistically solves nontrivial differential equations by hand these days.
sannee··on Teaching CS in the schools
> The myth that kids that age are all digital natives and hence much more adept at learning CS amd programming is wrong.

It feels sort of like assuming that kids born after commercial aviation became widely available have some magical understanding of fluid dynamics.

sannee··on Gene drive used to turn all female mosquitos sterile
Because porting genetic modifications between species is really hard even if you intentionally try.
sannee··on Leaving Apple and Google: /e/ first beta
To be fair, people call drugs by myriads of names. Context usually helps to disambiguate between LSD and MySQL.
sannee··on MonkeySort (2012)
Does this avoid asking questions that would make the relation not a partial ordering? Is it even possible to implement that?
sannee··on Glowing mercury thyratrons: inside a 1940s Teletype switching power supply
Interestingly, the same word is used at some european universities to mean roughly "associate professor".
sannee··on The US chip industry starts to wake up to new competitive reality
> It's also probably why firmware engineers tend to write so much copy/paste code

This always seemed like limitations of the commonly used HDLs. Both Verilog and VHDL are extremely verbose and do not really allow a lot of abstraction. Even stuff like "I want this module to have a $common_interface" is hard to impossible without just copy pasting the definitions (sure, there are C macros) every time.

Isn't that usually called WPA Enterprise?
sannee··on EU to move ahead with cultural quotas for streaming services
You are missing the point. Each member nation should decide by itself about how open to outside cultural influences it is.
sannee··on EU to move ahead with cultural quotas for streaming services
EU is slowly cutting away sovereignity of its member states with regulations such as these. This is a very touchy subject for some of the european nations and "Hollywood production is dumb" is just an extremely stupid thing to bicker over at an international level. All it does is increasing political tension until another brexit happens.
sannee··on EU to move ahead with cultural quotas for streaming services
Anti-EU types usually base their rhetorics on globally enforced regulations coming from "Brussel bureaucrats".

Sure, I would not be surprised if this concrete instance of such a regulation was welcomed in these circles (consistency isn't strong suite of some), but the more broad point stands.

sannee··on EU to move ahead with cultural quotas for streaming services
This is the side of the EU that foreigners usually don't see. This is the reason there are movements for quitting in every member state (with varying levels of success).

The isolationism EU is beginning to display is starting to worry even me and the alternative is a bunch of UKIP-like nationalist which I am not really a big fan of.

sannee··on Female, minority students took AP computer science in record numbers
> It's a college level course offered to high school students.

I took the AP Physics C MITx course on edx (when I was in high school) and it was way below the level of our college Physics 1 course (electrical engineering, European university). Not saying it wasn't a great course (much better than anything my high school offered), but it just wasn't as mathematically rigorous.

Are introductory college classes in the US really so basic?

sannee··on Apple self-driving car in accident: California DMV filing
Because there might be multiple different development approaches to solve the same problem. It makes sense to explore more than one of them.

Some cars don't use LIDAR (Tesla), some use end-to-end machine learning (geohot thing), some are more of an "assistant" systems and others aim at full autonomy. It's unclear which of these approaches will yield results long term.

sannee··on California Moves to Require 100% Clean Electricity by 2045
I am fully comfortable with that (not parent though) and have even done so on several occasions.

You do realize we can detect contamination by radioactive elements in quatities many orders of magnitude lower than could conceivably cause any harm right?

On the other hand, I live in Europe and our local government has yet to produce a complete environment monitoring fail such as the Flint incident in the USA.

sannee··on Suicidal Vet Calls MDMA Treatment ‘a Miracle'
Given the high individual variance, dosing psychedelic substances by bodyweight isn't usually considered very effective at estimating the final effect.

Always start with a low/threshold dose first and go from there (this might be less practical for MDMA, where you want to limit repeated exposure).

sannee··on Georgia Tech Creates Cybersecurity Master’s Degree Online for Less Than $10k
As far as I can tell, the price here (Czechia) is based on language of the study programme not nationality. You can study in Czech for free even as a citizen of another EU (not sure about not-EU) country. I don't think it's particularly practical idea though. The fee for the english version was about 5-6k$ for academic year last time I checked.
sannee··on Georgia Tech Creates Cybersecurity Master’s Degree Online for Less Than $10k
Can't speak about Germany, but we have 100Mb/s symmetric internet for about 5$/month at the Charles University student dorms here in Prague.

Technically, there is supposed to be some fairly brutal bandwidth sharing and the speed is not guaranteed in any way but I never had my speedtest drop under 90Mb/s

sannee··on Tomu, a tiny ARM microprocessor which fits in your USB port
This looks like it's supported by a 3D printed enclosure. Otherwise I agree - you need >2.0mm thick PCB to prevent falling out and these are not offered by the usual cheap low-volume PCB manufacturers.
sannee··on Attempting to modify e-coli with CRISPR in my bathroom
> I don't want some "biohacker" accidentally creating AB resistent bacteria in their back garden...

There are much easier ways of creating AB resistant bacteria than CRISPR. In some countries, they even give out the necessary chemical reagents for free to anyone with a bit of patience!

sannee··on Attempting to modify e-coli with CRISPR in my bathroom
They usually don't sell deadly bacteria in kits aimed at high schoolers...
sannee··on The World Economy Runs on GPS. It Needs a Backup Plan
The reason your GPS receiver does not work on a plane is likely because it's processing algorithms aren't tuned for those speeds. The popular Ublox NEO-6M for example needs to be explicitly switched to "airborne" mode.

The fact that you are enclosed in a faraday cage also isn't helping, but they make planes from plastic now, so this shouldn't always be the case.

sannee··on The Octonion Math That Could Underpin Physics
Octonions are to quaternions as are quaternions to complex numbers (and complex numbers to reals). This is called "Cayley construction" iirc.
sannee··on The Octonion Math That Could Underpin Physics
> In the approach from the article it seems as you are picking a mathematical structure in the middle of nowhere

Quaternions were very popular way of expressing the "classical" physics around the 19th century (and the vector algebra we know today is in some ways just a derivative of quaternion algebra). Complex numbers are extremely useful in many fields even today. It's hardly in the middle of nowhere.

sannee··on Walmart patents surveillance tool that can eavesdrop on workers
As someone with mild social anxiety, I, for one, welcome our new robot overlords.

I hate having to talk with a stranger just in order not to starve to death.

sannee··on ARM: “RISC-V Architecture: Understand the Facts”
> unless you want to waste most of your FPGA on a soft core

Huh?

As an exercise in FPGA stuff, I decided to use PicoRV32 on a small MAX10 8k FPGA. The core itself consumes easily under a quarter of the logic blocks.
