sannee··on Indonesia election: More than 270 election staff die counting votes
> old age and that population is very unlikely to be working counting votes.

Why do you think so? Here, election committees are stereotypically composed of retirees that have nothing better to do...

sannee··on Downsized dwellings: Inside Tokyo's tiny living spaces
This looks about as big as my college dorm. Not exactly comfortable (given the fact that I work with hardware and have lab setup here) but also not the end of the world.

If I only needed a computer, I would actually have shit ton of space.

sannee··on Antenna Theory (2016)
The analysis part of engineering is, thanks to modern computers, practically "done". However, we are still not able to do synthesis well. We also have exact mathematical models for that, but it usually amounts to NP-hard problems (think integer optimization).
sannee··on Huawei savaged by Brit code review board over poor dev practices
> What probably happened is that many of Huawei's programmers are EEs who happened to take a programming course or two in college.

Oh yes. Most of my classmates have picked EE over software engineering because they "dislike programming". The fact that EE (and any other engineering field really) is now mostly about programming anyway is lost on them.

People designing EE study programs are usually completely unaware that, well, computers exist. I have literally heard "Want to learn programming? Uh, just spend a weekend playing with Matlab or something and you will be set.".

sannee··on Study Linking Autism to 'Male Brain' Retracted, Replaced
> identified a problem with the script

Shitty academia code strikes again. It's sort of unfortunate that most of academic fields have turned to domain-specific software engineering, which graduates are woefully unprepared to do properly.

sannee··on How to open a microchip and see what’s inside
Is EE actually the correct field to study for formal verification? I have been looking into this at one point and it seemed very much within the realm of computer scientists.

For instance, our EE study program does not include even basic computability theory, the formal logic/graph theory was pretty minimal and besides some K-maps also zero boolean function theory.

This compared with the CS program that contains multiple very in-depth courses exactly on those topics which seem pretty critical for formal verification of hardware.

sannee··on How I'm able to take notes in mathematics lectures using LaTeX and Vim
> Because it's very much an edge case and he hasn't passed yet.

I am fairly sure he passed more than one course with this approach. The blogpost says that he started using LaTeX to take notes during his second semester. The screenshots show introductory complex analysis, which is usually taught somewhat later.

sannee··on Visualizing Complex Functions
I am an EE and our complex analysis class definitely did define complex numbers "rigorously" (in the usual R^2 with multiplication -> wow, it's a field way, none of the fancy algebraic closure stuff).

However, later I spoke with some of my classmates and it turned out that this left absolutely zero impression on them and they still believed that "we define i to be sqrt(-1)" high school rubbish...

sannee··on College Cheating Scandal: An Admissions Officer Speaks Out
This is effectively what Czech STEM universities do. The supply is way bigger than the demand and as such getting even to the "top" study program is trivial.

Not sure it's very effective seeing the 60%+ failure rates in the first year. These people could spend that year doing something they are more suitable for.

sannee··on Scaleway cloud adds AMD EPYC instances
I've had similar issues. Network outages, server power cycles taking forever etc. The only good thing Scaleway is for is hosting Tor exits, which they don't seem to mind.

To add to the network stack comment - they assign _single_ IPv6 address to your server. Not a /64 block, just a single /128 address. I have no idea what they were thinking.

sannee··on A Touchpad Embedded Keyboard
Not having tactile feedback seems annoying given that most home media center controlling happens with the lights turned off.
sannee··on Is Your Cat 6 Cable a Dog? (2013)
Can also mean: Works with devices A and B, stops working with devices A and C.
sannee··on The Chinese scientist who allegedly created CRISPR babies is being detained
Are you being hyperbolic or do you actually think that the current (or at any point in the next few hundred years) genetic modification technology is capable of doing anything close to transforming humans to "fly-hybrid creature"?
sannee··on Ibuprofen alters human testicular physiology to produce compensated hypogonadism
> high, full doses of 2,400 to 3,200 mg daily

Holy shit that's a lot of ibuprofen. If you are taking that much every day, you definitely have some more pressing concern than liver toxicity...

sannee··on Ask HN: How can I make the most out of high school?
> I don't know how to make close friends.

In my experience, it's much easier to do with people you have something in common. I didn't even know the names of most of my classmates in high school.

> Will college be the same or different than high school?

The best thing about college was the fact that other people stopped feeling like a bunch of scripted NPCs.

sannee··on Why Are Printed Circuit Boards Usually Green? (2017)
> It would be a lot easier for teachers to say "plug the red wire into the red pin" instead of "the top right ... no, other top, turn it around".

Well blowing stuff up is part of the electronic learning experience isn't it? :)

sannee··on Build your own bare-metal ARM cluster
If you are using (two) DHCP servers in "proxy" mode as suggested in the official tutorial, it indeed is extremely unreliable. I think the firmware just does not accept the PXE-containing response if it arrives second or something.
sannee··on Build your own bare-metal ARM cluster
Note that the Raspberry Pi can boot over PXE without an SD card these days, which should make for a much more reliable setup.
sannee··on How Juul became worth $38B
Psychoactive drugs have different effects on different people.

For me, caffeine is the drug that does not really do anything (higher doses in the 300mg+ range are definitely noticeable, but mostly by the physical side effects). Nicotine chewing gum produces a short-lasting mild stimulation (and I have to take a 4mg one, even though I am a non-smoker).

sannee··on Number of babies born in Japan is the lowest since records began
Because children in Africa are not going to finance retirement of japanese elderly.
sannee··on Improvisational theater can reduce anxiety in teens who struggle socially
Participation was voluntary, which likely skews the results. I can't imagine signing up for anything similar to this myself...
sannee··on LiveAgent: Over $250K monthly recurring revenue with a spin-off project
The student might be still getting paid by the company. I see no admission of them being unpaid...
sannee··on Two abandoned Soviet space shuttles left in the Kazakh steppe (2017)
In the article, they say that "they're not even owned any longer by the Russian government.". So maybe it's just garden variety trespassing on private property?
sannee··on Coding for the World's Trickiest Chip – SEGA's Saturn DSP [video]
These days, we accelerate DSP tasks using GPUs :)
sannee··on For a brief period, the Windows kernel tried to deal with gamma rays
> I wonder if it’s possible to detect solar flares in these logs. Need to find a good data source for them. Are there any other events generating lots of radiation that may affect servers?

Cosmic ray showers [1] potentially. My prediction is that there should be "clusters" of bit errors every few minutes or so (given sufficient amount of servers...).

I was talking to a sysadmin at a local company running a few thousand servers about getting their ECC error logs in order to look for these, but scraping them apparently wasn't trivially managable for them.

sannee··on Ask HN: I've been a programmer for 6 years, and I can't solve basic CS problems
> The requirement is to pass a one time drug test

Wait what? Where do you live that software developers are drug tested?

sannee··on Alarm over talks to implant UK employees with microchips
Are you sure these tags are RFID? I have only ever seen magnetostrictive tags [1] (but I don't buy expensive clothing...).

sannee··on 96-core ARM supercomputer using the NanoPi-Fire3
Can these NanoPis boot over PXE? I was pleasantly surprised a few weeks ago by the fact that the Raspberry Pi can do network boot without an SD card.
sannee··on Intuitive Understanding of Euler’s Formula
Wasn't some sort of engineering-grade complex analysis part of your EE (undergraduate?) curriculum? I am sort of surprised Euler's formula would be a "secret weapon" in EE classes.
sannee··on Pirate Party Leader to Be Prague mayor
Czechia is in general one of the safest european countries [1]. I am quiet european laptop carrying male (-foreign) and have ocassionally walked through deserted industrial areas/streets of Prague well after midnight and never felt significantly threatened.

Rowdy and drunk groups of tourists are the most unsettling thing that I occasionally encounter, so maybe it's better to avoid tourists areas instead?
