homeless_engi··on Some Junk Theorems in Lean
As I think another commenter hinted, the binary expansion of 7 is 111. And indeed, 1 = 1 = 1
homeless_engi··on Linux computer designed with AI boots on first attempt
My reading of this is that they asked the system to redesign the PCB that was used in the i.MX 8M reference system-on-module. It looks like they take a parts list, a PCB shape, and a rough floorplan and pass that to their tool, which spits out a PCB design.

I could actually see myself using this tool, as someone who trained as an EE and still likes to tinker with electronics. It would be fun to just assemble a parts list and a rough layout and then receive a working electronic device a few weeks later with minimal work.

Yandex is also yellow on that map. It lists five search engines that run their own crawlers -- Google, Bing, Yandex, Mojeek, and Yep

homeless_engi··on How to sequence your DNA for <$2k
Thanks for the kind words! I have not written it up but would like to. A word of warning: by trying to get into sequencing, I eventually burned through ~20k USD of student loans (still unpaid) with little to show. Nanopore sequencing also requires some specialized equipment (at least a micro centrifuge and micropipette and possibly more) which is not cheap.
homeless_engi··on How to sequence your DNA for <$2k
Hi, believe it or not, I have actually done what the authors were attempting. I used saliva rather than blood as a source of DNA and extracted it using a Qiagen kit.

My Nanopore flow cell had nearly every pore working from the start. So I would say that is not normal. Maybe it was stored incorrectly.

Adding on: Claude also gave me the following line which was necessary to get the model weights to download from HF. This might be obvious for anyone familiar with HF but it helped me so sharing here!

homeless_engi··on Oxford loses top 3 university ranking in the UK
Yes, seems I misunderstood the original text. Thanks for the clarification.
homeless_engi··on Oxford loses top 3 university ranking in the UK
I think the real story here might be the line below:

"Durham University improved by 30 places year-on-year"

Seems a bit suspicious, no? What methodology change led to this result? How can a university that was previously not as well-regarded become the #3 in the country overnight?

homeless_engi··on You can now buy eggs from in-ovo sexed hens
The US culls 350 million male chicks per year, per this article. Wikipedia says billions of male chicks are culled worldwide, which seems plausible when accounting for EU, China, India, SA, SEA etc. The citation on Wikipedia looks legit to me as well.

Edit: Wikipedia does indeed cite several different figures, including a "billions" number which does not seem plausible. Thanks monster_truck for pointing this out, and apologies for my misunderstanding!

homeless_engi··on You can now buy eggs from in-ovo sexed hens
Male chicks are not feed nor raised but rather fed into a device quite similar to a wood chipper shortly áfter birth. You can read more about it here [1] or find some quite graphic videos on YouTube. This is addressed in the article:

"In polling, only 10% of Americans correctly identify that male chicks in the egg industry are killed shortly after hatching. A plurality mistakenly believe these chicks are raised for meat, and another 10% even think that male chickens can lay eggs. Most people are surprised, and often disturbed, to learn the truth: in the United States alone, approximately 350 million male chicks are routinely culled each year, typically by methods such as maceration (being ground up alive)."

East Asia has lots of highly walkable cities with great public transit -- even a few you might not have heard of. Not just Tokyo, Seoul, Shanghai, Beijing but also Shenzhen, Chongqing, and Hangzhou to name a few.

homeless_engi··on Charging electric vehicles 5x faster in subfreezing temps
Many EVs (Teslas) already contain a heat pump to warm the battery. I presume that improved battery chemistry would supplement this -- but maybe replacement would be possible?

homeless_engi··on Electron band structure in germanium, my ass (2001)
Yes, maybe true. But it's a pity that was not reflected in their final grade.
homeless_engi··on Harvard concluded that a dishonesty expert committed misconduct
In my experience most/all academics crave a certain type of attention. It is an occupation where you get promoted in part by how famous you are (how many citations your publications have, which conferences you attended, etc.).
homeless_engi··on Jupiter's ocean moon Europa, thought to be habitable, may be oxygen-starved
Yes! From the article: "The team found that about 13 to 40 pounds of oxygen is generated each second by Europa’s surface. ... While earlier studies reported widely varying ranges up to 2,245 pounds per second, this result shows the higher end of that range was unlikely."
homeless_engi··on A neural code for time and space in the human brain [pdf]
Not an expert, but one application of neural decoding you may be aware of is brain machine interfaces (eg Neuralink). By decoding motor intent we can create devices which offer movement to paraplegic individuals with external robotics. Decoding neuronal activity in other parts of the brain could allow us to directly interface with other neural functions. Imagine a machine that could interpret your perception of space or time (or even modify it).

Another application is in computing. Advances in the understanding of neuroscience have stimulated the creation of artificial neural networks (for example, the convolutional neural network was inspired by the cat visual cortex). Understanding how the human brain encodes concepts such as time or space might help us to design artificial systems.

Finally, the most important aspect of this work is (imo) advancing basic science. We don't understand how the brain works, and work such as this brings us closer to solving the grand mystery of neuroscience.

How about the issue of astroturfing or botting?
homeless_engi··on Tesla power steering probe upgraded after thousands more incidents reported
The vehicles affected were not drive by wire. It sounds like you are referring to a system in the Cybertrunk, but this article is discussing Model 3 and Model Y which do not have a physical steering column.

Oh... thanks, I will not do that in the future.

Does this violate HN submission guidelines?

" On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic. "

Odd that this topic is on HN, it seems to violate submission guidelines:
