Unfortunately, the trend seems to be that as manufacturability of a product increases, repairability decreases. A simple example is the heavy use of fragile, easily broken clips to hold on parts that used to be held on with bolts and screws.

How do they attach those bond wires? Seems difficult and fiddly!

I don't understand this service. I feel it takes away from the experience. One of the few hobbies that gets you outside and under the stars and learning to navigate the sky and its motions was already being reduced to pressing a few buttons on a laptop connected to the scope. Now, you don't even leave your house?

I was taking taurine 1000 mg per day but stopped when I heard a plausible link to colon cancer. Having a strong family history, it wasn't worth the risk.

Eagerly awaiting the results of this trial: https://ascopubs.org/doi/10.1200/JCO.2024.42.16_suppl.TPS363...

Uncertain though how they will separate the effects of the taurine from all the other stuff including sugar that is contained in energy drinks.

I think this is a hard theory to pin down as it might depend on how much taurine producing bacteria an individual has in their gut B. wadsworthia, so two people could have very different outcomes while taking the same amount of taurine.

Apologies for the double post. I got a "link expired" error when submitting so assumed the original post had not succeeded.

It appears that the trial is still ongoing: https://www.cancer.gov/research/participate/clinical-trials-...

The theory is that the taurine added to the drinks is feeding gut bacteria that then produce hydrogen sulfide that damages the intestinal lining.

If Tesla Insurance is paying out for parts to fix damaged Teslas aren't Tesla effectively paying themselves and so recouping some of the paid out monies? Sure, it goes on a different balance sheet, but it's all Tesla in the end.

On second thought maybe this loss ratio is based on buying parts at cost from the auto division and so there is still a loss there to Tesla who has to supply them from China or whereever.

Two interesting things I took away from that were first that the uncertainty and constant changes of mind by the President on the actual rates and lack of reliable communications were almost as harmful as the tariffs. Second, that there is a "snowball effect" in that you often have to pre-pay, so you take out more loans at a worse interest rate to make your order and then if because costs went up, you order fewer items as well as being hit with a higher per-item cost.

The whole thing is a mess and shows how incompetent the current implementation is.

In the realm of fiction, they released edited versions of Roald Dahl books that were more politically correct and designed to be less frightening to the fragile children of today.

I like it! I spent an enjoyable 10 minutes clicking around and checking out what battles took place at various places I have lived in the US and Europe. Is there any way of adding country/US State boundaries for the more geographically-challenged among us? I can usually find my way around using the coastline and following rivers, but I get lost in the middle of large continents occasionally.

Prime customers tend to buy more stuff from Amazon, so they get you that way maybe.

I had mixed feelings about those that demonstrated their knowledge by answering the question extremely thoroughly with a lengthy treatise. On the one hand, their answer was a great resource for deeper understanding, on the other I just wanted a one-liner to solve my problem and go on with my day!

Do you feel the H1B system denies jobs to Americans or suppresses wages for those with jobs?

Many cities have an organized theft problem and are doing very little about it. Even when the police catch the perpetrators, they get little to no punishment. There doesn't seem to be much of an effort to go after the fencing networks either. Things seem to be getting worse in a lot of urban areas too, where I live I have noticed the decline over the last 5 years which has led stores to not only lock things up, but a lot of them hire security guards or off-duty cops to man the entrance/exit and they also have closed entrances to make everyone enter and leave through a single set of doors.

As well as the organized crime, I think there is a culture problem in some areas where it is "OK to steal from the man", well it is until the store in your area closes and now you live in a food/retail desert and have to take a bus to buy anything.

Curious how navigation at night was not possible without expensive equipment, sounds like they were relying only on starts in the morning and evening? Are the measuring something like angle of those morning/evening stars or their set/rise times with respect to the sun?

Those stories about people (the internet generation) not being able to read anymore are true!

It's better than using it on crypto mining which is a huge waste of resources for something so useless to humanity.

I think words like these are also used now as a means of signaling...well.. something about your views or beliefs or group identity.

Reminds me of the politically-correct nonsense in the 90s with *-challenged, like a short person is now vertically-challenged, a bald person is folliclly-challenged or adding *-technician to something like dish-cleansing-technician.

I thought at first this was discussing why early CD-ROM devices had a flimsy tray that came out and held the disk vs. just being able to push the CD into a slot and have it automatically pulled in like on modern devices.

Unfortunately, a lot of those meal toppers for pets are made using freeze dried raw chicken parts. They often use the fact they're raw as a selling point.

I remember Lexmark just before things started to go bad for them, back when they still had a huge campus with multiple buildings, developers had their own office or shared with one other person and they owned their own huge park with a disk golf course. They even built a new building on campus for an employee daycare and acquired multiple software companies to add services on top of print.

We had huge teams of software engineers, embedded software developers, mechanical engineers, electrical engineers chemists and specialists in microfluidics. We designed our own image processing ASICs, had specialists in color and perception, had a whole team dedicated to just Linux and dedicated software librarians. There was a team working just on Android. We contributed back to Linux as well as Yocto/Bitbake. The first sign of decline was when suddenly (for me anyway) they announced the closure and sale of their entire consumer inkjet division followed not long after by commercial inkjet. They sold all the inkjet assets off to a partner manufacturer company a bit like Foxconn.

It was wonderful for a while and I am sad to see things get potentially worse for them.

When they hired me out of college, they paid me a $5000 relocation bonus, paid a specialized company to organize the move (even offered to find me a realtor and help sell my house if I had one), paid the moving company in full, paid to have my car relocated there, paid for hotels during the move and then paid me another $5000 to cover any miscellaneous costs from moving that I might incur. They also paid the taxes for me somehow, I guess by adding extra to my paycheck. Never seen the like before or since.

The vastness of the Pacific and indeed the planet's oceans is something I noticed was missing from the article. I think of it in terms of detection, you can have the sophisticated technology and perhaps focus it on one area or choke point, but in general it will be very hard to search the entire ocean for a nuclear ballistic missile sub.

Drop a submarine-sized object at a random location on land (a much, much smaller search space) and I bet it would take a long time to find despite all the earth observation satellites at our disposal. The oceans are much bigger, and have a whole other dimension (depth) and the the subs move.

Is it a nice language? As an embedded software person who writes mostly pure C (and hates C++), I have been avoiding Rust as it seemed tedious and annoying when I last dipped my toe in. Perhaps I am just old and stuck in my ways :) I would love it if Rust was nice to use, especially if that is where the future of embedded is.

Strain-wave gears are becoming popular in many areas including astronomy for sky-tracking telescope mounts, they're kind of odd but clever.

If you search on YouTube there are a couple of good videos where people have 3D printed their own to demonstrate the principles

The idea of shining polarized light through gears made of Lucite to view the stress lines at the point of tooth contact is genius!

This old training video is great too, it also mentions the idea touched upon in the article that gear teeth are levers:

From my admittedly limited knowledge gleaned from occasional PopSci articles posted here on HN over the years, don't they use plasma trapped in magnetic fields to contain the reaction and not a particular metal?

I'm still waiting to see any (net) value to society from our current AI. So far I believe it is negative despite being a paid ChatGPT user myself.
