ckocagil··on Show HN: Reverse-Engineering a Switch Lite with 1,917 wires
Also games became very affordable compared to the time period you mentioned. The number of games worth playing were much, much fewer. Not to mention the F2P or even open source games we have now.
ckocagil··on Power over fiber
It could be used to power a LOT of sensitive test instruments.
ckocagil··on A DIY near-IR spectrometer
Nice project. A low DA capacitor Cf in parallel with the gain setting resistor Rf can average out more noise if needed. It can even deal with the mains noise if that remains an issue. Another potential improvement: addition of an optical chopper wheel to deal with the entire system's 1/f noise. The downside is this would require higher sampling rate which would then get demodulated + filtered externally. Would also limit Cf to higher frequencies.
ckocagil··on Touch Pianist
Rachmaninoff's Prelude (op 3 no 2) is incredibly fun to play!
ckocagil··on Video: Iranian Navy Warship Fires on Oil Tanker in the Strait of Hormuz
Tit-for-tat going on for years. US seizes tankers carrying Iranian oil. Iran seizes oil tankers in strait of Hormuz as a reaction. Rinse and repeat

ckocagil··on Quantum Mechanics: Schrödinger's discovery of the shape of atoms
I had posted this a few years back but it didn't get noticed back then. Posting again because this video is exemplary in its clarity and it's a topic the HN crowd might like. This is also one of the best science education videos I've seen and I keep coming back to it every few years.
ckocagil··on Extracting the GameBoy ROM from photographs of the die
You can if there's enough space between the lens and the die.
ckocagil··on Low-cost open source device can measure air pollution anywhere
A lot of these cheap, portable sensors "cheat" in one way or another. E.g CO2 sensors that assume they'll be subject to open air once every few days, using that minimal CO2 value as a baseline. So while they give numbers which can be useful if the user is aware of its limitations, they're far from being analytical tools.

In contrast PM is pretty easy to get right. Shine laser, count particles.

ckocagil··on The lost art of lacing cable (2018)
IMSAI Guy on Youtube made a video on cable lacing just last month. It shows a few different standards and knots: https://www.youtube.com/watch?v=EN8dDR4ipBU
ckocagil··on Casio-F-91W die-shot
I guess you'll enjoy this one too: https://zeptobars.com/en/read/AD9361-SDR-Analog-Devices-DAC-...
ckocagil··on US Copyright Office refuses application with AI algorithm named as author
That brings the question: in order for a work to be copyrighted, does a human need to put "some" effort into generating that work (prompt engineering, tweaking knobs, etc.) or does it suffice to click a "generate" button?
ckocagil··on Xiaomi’s humanoid drummer beats expectations?
So this paragraph summarizes it:

>What was the most challenging part of this research?

>Ren: The most challenging part of this research was that when receiving the long sequences of drum beats, CyberOne needs to assign sequences to each arm and leg and generate continuous collision-free whole-body trajectories within the hardware constraints. So, we extract the basic beats and build our drum beat motion trajectory library offline by optimization. Then, CyberOne can generate continuous trajectories consistent with any drum score. This approach gives more freedom to CyberOne playing drums, and is only limited by the robotics capability.

Nice research, but I'd be more impressed with an online optimizer that only looks ahead about a dozen moves. The point of a humanoid robot is to put them in environments with uncertainty where a limited library of optimized moves won't be enough. Still, AFAICT, it's a fully closed loop from the cameras to the motors so that's nice.

ckocagil··on The ATtiny 2-Series
Yes, they are expensive. This is what prompted a lot of people to switch to alternatives like Padauk. They had supply issues, though :/
ckocagil··on Fuchsia Workstation
This is correct. Gyp came first, then Evan Martin built ninja as a faster make, then Brett Wilson built gn ("generate ninja") because Gyp wasn't intuitive or convenient for a lot of use cases. I don't know if Googlers had an internal Blaze back then - I'm an outsider :)
ckocagil··on U.S. Labor Secretary throws support behind classifying gig workers as employees
So you're proposing we go back to the 19th century?
ckocagil··on Europe Is Guaranteeing Citizens the Right to Repair
Are they idiots, or do they get something out of it?
ckocagil··on My Experience at Apple
...and why would he do any of those?
ckocagil··on Working at Apple (2011)
Didn't Jobs fire employees on the spot after asking them questions in the elevator and not liking his answers? Which prompted people to avoid taking the elevator with him.
ckocagil··on YouTube Class Action: Same IP Address Upload Pirate Movies and File DMCA Notices
They can tell just by the first byte of the IP address. CGNAT addresses start with 100.
ckocagil··on Teardown: Identifying Apple M1's distinct circuit blocks
For regular ICs I put them in a test tube with nitric acid and heat it to extract the die. Then to image the die you'll need (in order of preference) an electron microscope, or a metallurgy microscope, or a regular bio microscope.
ckocagil··on We Love GPLv3, but Are Switching License to Apache 2.0
Are you thinking of AGPL instead of GPLv3?
ckocagil··on Google illegally spied on workers before firing them, US labor board alleges
Laws are political.
ckocagil··on Ask HN: Has anyone seen smart TVs connect to unsecured WiFi without permission?
There's probably still an external or PCB antenna. Wrapping it in aluminum foil should do the trick.
ckocagil··on UVB-76
The next step is installing Fldigi, routing the WebSDR browser audio into it and decoding various modulations.
ckocagil··on FrontPage: The Good, The Bad, and The Ugly
It's very important to remember that Facebook's standardized UI played some role in making it successful. I don't think it would be as successful were it as customizable as MySpace.
ckocagil··on ESP32-C3 WiFi and BLE RISC-V processor is pin-to-pin compatible with ESP8266
That's not ST, it's by the Chinese company GigaDevice that makes (decent) clones of the STM32 series. Your point still stands though.
ckocagil··on AB07-USB3FMC: The $1.65k eval board they can't be bothered to test
Come on, you need to at least read the datasheet and errata of the Broadcom SoC. Oh... There isn't one... Unless you're purchasing millions of chips from them and signing an NDA.

Seriously, why the hacker community even touches the RPi is beyond me. It is a ridiculously closed product.

ckocagil··on Open Letter from Facebook Content Moderators
"Love it or leave it" means there is no room for discussion. It can also be considered a veiled threat especially given its historical use.

It's a false dichotomy. I already told you, you don't live in a capitalist system. You live in a hybrid system where all markets and contracts are already regulated.

If you believe otherwise, try ignoring labor laws. Try ignoring OSHA. Try ignoring EPA. Try getting someone to sign an indentured servitude contract. You'll quickly learn that the world isn't that simple.

ckocagil··on Open Letter from Facebook Content Moderators
False dichotomy. Economic systems contain hundreds of sliders a country can adjust, from various tax rates to workers' rights. Adjusting one of these has nothing to do with Stalin's USSR or Mao's China, so I don't understand why you're bringing those up.
ckocagil··on Open Letter from Facebook Content Moderators
You don't live in a capitalist system. You live in a hybrid system that is heavily regulated. The way these regulations are agreed on and applied is what really matters. Your comment is not only wrong, it is also rude in that it disallows discussion and can be summarized as "love it or leave it".
