As I think another commenter hinted, the binary expansion of 7 is 111. And indeed, 1 = 1 = 1

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.

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.

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!

Yes, seems I misunderstood the original text. Thanks for the clarification.

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?

New comment by homeless_engi in "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!

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.

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?

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.).
