sannee··on Prusa MINI: Smart and compact 3D printer
> small company

iirc they have well over 200 employees at this point.

sannee··on Prusa MINI: Smart and compact 3D printer
The fact that you can repair your printer by using your printer is a big selling point imho.
sannee··on Prusa MINI: Smart and compact 3D printer
Too bad they don't have a proper kit version. If it was 100$ cheaper (same ratio as the MK3S), I would definitely consider buying it.
sannee··on In Defense of Richard Stallman
I think it is safe to assume that the author is super good at reading comprehension. The SAT [1] scores of MIT students seem to be in the top 5% of population [2].

sannee··on In Defense of Richard Stallman
Being capable to extract precise logical meaning from text is something everyone with STEM education learns in their introductory mathematics courses. It has nothing to do with social ability.

> visiting professor has a poor grasp of social context and an inability to synchronise with other people.

I am not that interested about the broader political context. I would like to know who (and why) shot Franz Ferdinand so to speak.

sannee··on In Defense of Richard Stallman
> There are two possibilities here. Either the author of the Medium post was not capable of correctly parsing the sentence, or she didn’t care about truth and was leveling as many accusations as possible in the hope that one would stick.

Either I am vastly overestimating the quality of american top university education, or the first option is highly unlikely. So, who benefits from Stallman getting removed from the picture? Or, given that the original author was also from MIT, maybe it was just some sort of personal grievance?

sannee··on Echo Frames – Eyeglasses with Alexa
Prusa did this way back: https://twitter.com/josefprusa/status/425772744777940992

Unfortunately the source code disappeared from thingiverse...

You can literally buy prescription glasses (including the lenses) for like 20$ on AliExpress. How much cheaper would you want them to be?
sannee··on Ask HN: What things do you wish you discovered earlier?
Blindsight by Peter Watts. It's great at avoiding the "benevolent aliens that are basically just weird humans" concept that most other sci-fi books seen to enjoy.
sannee··on Ask HN: What things do you wish you discovered earlier?
If we consider Three Body Problem as hard sci-fi (see above), then Children of Time definitely clear that bar too.
sannee··on It Shouldn't Be This Hard to Responsibly Fly a Drone
Because if the drone pilot loses control and you get hit by a falling drone, you are guaranteed a trip to the hospital [1] [2]?

sannee··on Malicious attack on Wikipedia – what we know and what we’re doing
CloudFlare has strategic business partnership with Baidu [1]. They are very likely to cooperate with the chinese government to implement the great chinese firewall.

Additionally, helping to block Wikipedia because China says so is much easier to excuse than blocking 4chan - they would just be complying with local regulations after all.

sannee··on Malicious attack on Wikipedia – what we know and what we’re doing
Wikipedia is blocked in China. It's politically undesirable for 1/8 of the human population...
sannee··on Need a USB Cable? Build One
Interestingly, even the full speed spec (which is likely what the keyboard is running at) requires a shielded cable (which the one linked in the post isn't).
sannee··on ESP32/ESP8266 Wi-Fi Attacks
> They're neat devices but not really used for anything critical.

Well, they have to be used _somewhere_. It's not like Espressif is achieving the economy of scale for a 3$ module by selling to hobbyists...

sannee··on Crispr now cuts and splices whole chromosomes
I am not a biologist, but I doubt that. If you want to do this to an embryo, then abortion is a much saner option option.

Doing this a a living person would be pure madness, given the fact that we can't yet CRISPR even simple edits and deleting a chromosome (how would you even target just one of the copies?) is something much more complicated.

sannee··on WTF – A personal information dashboard for your terminal
Yeah, this makes it unusable on my terminal because I have a custom color scheme.

The background of the borders matches my terminal while I can't get the background of the widgets to match because of this.

EDIT: Hah, specifying "transparent" makes it work

sannee··on The Path to Dijkstra’s Handwriting (2013)
I have changed my handwriting away from cursive during my mid-teens and I was surprised how easy it actually was. I literally just printed out a bunch of pages from [1], practiced for a few days and it was done.

Now I can't really write cursive even if I want to. My signature, which is in cursive, has morphed to an unintelligible mess over time.

sannee··on The Path to Dijkstra’s Handwriting (2013)
At least in Czechia, cursive was taught until very recently. These days kids mostly learn Comenia Script [1].

sannee··on Introduction to Applied Linear Algebra Vectors, Matrices, and Least Squares [pdf]
As a rule-of-thumb, I would stay away from any "linear algebra" textbook that does not even have definition of an abstract vector space in the first few chapters. In a sense, it's like programming without data types.

When I was in high school, I learned linear algebra from similar textbook, but it wasn't until college (and that was an engineering linear algebra course!) that I got any sort of understanding of what it's really about.

sannee··on GE's smart light bulb reset process is a masterpiece of modern techno-insanity
> If you have kids they play with turning the light switch on and off. So I can see the need not to reset by accident.

These are "smart" light bulbs, so I am guessing you are not supposed to control them by cutting of their power with a physical switch.

sannee··on My Home Lab Server with 20 Cores / 40 Threads and 128 GB Memory
I live in a dorm room and keep an R610 about three meters from my bed. You can use some magical IPMI commands to disable the internal fan feedback loop and replace it with a custom one (usually the defaults cool the server to around 30C, which is not really necessary). This makes the server more quiet then the small fridge I also have in the room.

The 100W power consumption definitely makes the room warmer. It is approximately like having another person present.

sannee··on Oscilloscope Video Monitor (2011)
The build I have seen was driving the electromagnetic steering coils directly, bypassing any original TV circuitry.
sannee··on Who Did the Math for General Relativity First, Einstein or Hilbert?
Yeah - and if you believe Watsons autobiography, she was strongly opposed to the idea that DNA had a helical structure until Watson and Crick basically figured it out and presented her with some very convincing arguments.

Franklins contributions seem pretty overstated compared to how people don't mention all the other people involved that had some critical insight.

sannee··on I tried to pay with Bitcoin at a Mexico City bar. It didn’t go well
You don't even have to use the PIN if you are using NFC and paying under 500 CZK.
sannee··on I tried to pay with Bitcoin at a Mexico City bar. It didn’t go well
> I didn't have to sign anything

Hmm, I guess you are american (with a magstripe card?) traveling in the EU? I never had to sign anything when paying with card here.

sannee··on Linode GPU Instances
You can't use nouveau for CUDA, which sort of negates the whole point of having a GPU in a server in the first place.
sannee··on Remote Code Execution on Most Dell Computers
> - DNS Hijack the victim.

This is the trivial one. You can just set up a free Wi-Fi access point next to a restaurant that people from company-you-want-to-hack like to visit.

sannee··on Remote Code Execution on Most Dell Computers
Dell _laptops_ running Windows even. When I read the headline I freaked out a bit because I have Dell server...
sannee··on Remote Code Execution on Most Dell Computers
The soft plastic casing definitely cracks easily. On the other hand it does not fail catastrophically. I have dropped my Nexus 5 on the floor more times than I can count and while it has miniature cracks around the button/power connector it's nothing that prevents the phone from working.
