> Any company can get scammed on crap parts, either because they took a gamble trying to save a few cents or because those parts were all they could get their hands on

It's true, though in the latter case, it can't be helped.

I worked at an integrator from 2002-2005. Small outfit, building PCs and servers for businesses and local agencies. As a new member of their engineering department, one of the first issues we got asked to investigate was to look at heightened failures of network cards. Back then, we bought the ubiquitous 3Com 3C-905. All of our PCs were subjected to a battery of functional tests before shipping, and we were finding that an abnormal number of the cards were failing.

We started looking at the failed ones more closely, and found them running extremely hot. These were passively cooled cards, and didn't need a heatsink under normal conditions. But on any of these, you couldn't hold a finger against without burning yourself. Functional ones as well.

We got the batch of serial numbers, and send them to 3Com to ask what might be going on. And the answer we got was that they didn't exist.

A bit of back and forth between 3Com, the distributor (a well-known and established company) and ourselves led us all to believe that they were a counterfit batch that entered the supply chain. We tracked down all of the cards from that order, and opened up every boxed PC that was to ship with one (I'll never forget the company president with his business shirt sleeves rolled up and a box cutter in his hand. He set the tone) and we pulled out every one.

We sourced from reputable places, and I don't recall another instance of that occurring while I was there. But it was an interesting event in my career, and one I'll never forget.

>Are they using scrap metal?

Did you have the captions turned off during your view? I don't know how captions were turned on (is that now a default thing for YT), but there's a line that says it is scrap metal.
Wow was that a lot of words to say that there’s nothing special about AI because it is created by humans.

> And when I'm charging it's nice that most cars tell you the number of kilowatts you are receiving, but it would be nice to know exactly how many amps and volts as well.

Well, it's giving you kW, and you already know voltage from the charger, so you can work out the number of amps being pulled, roughly.

Not that I am disagreeing; it would be nice to see all three figures without having to try to work out any of them.

It isn't only conservatives who criticise "woke".

Here's a lengthy article by the African-American Marxist Adolph L. Reed Jr (emeritus professor of political science at the University of Pennsylvania), attacking it too: https://newrepublic.com/article/160305/beyond-great-awokenin...

Are you similarly dismissive of left-wing criticisms of "woke", or are you okay with those?
Wow, so glad to have seen this conversation. I checked my gmail spam folder as a result, and saw a message from someone I haven't talked with recently, but have definitely emailed with in the past. As others have noted, prior bilateral emailing should be a very strong signal that a message is not spam. I will make a habit of checking my gmail spam folder at least monthly...
Another comment from this thread seems pretty cool to me.

Ah I meant if the AI is so capable in writing code there won't be any need for a human to read the code anymore. The "code" will be a bunch of english requirements, like an essay describing the program. Its unclear what language ChatGPT would use in that case (and who cares if the human is no longer important?).
For one, electrolytic capacitors can have pretty large tolerance for their initial value. The question then is also whether a fresh cap’s value is closer or further away from the value the old cap initially had compared to what it drifted to.

More generally however, you just don’t need to replace a capacitor in something that works well and that is not anticipated to break catastrophically because of the capacitor plague.

If the caps do eventually drift off so far that it affects operation, replace it then, and then it makes sense to take the opportunity to replace others as well as precautionary measure.

Sometimes you know that a non-plague cap will likely fail because it’s right next to a massive heat source, and you may replace it early with good reason.

But sometimes I see people literally replacing 80 caps or more without reason, when I have the same device sitting at home with its original caps, still doing its job well within spec for years.

So many. For one, working better. Having a head unit that boots up instantly and connects to Bluetooth instantly would be huge.

Second, audio controls that match or exceed what I can do with my phone from which I’m playing audio. BMW’a click dial interface was fantastic the last time I used it. Basically something that is optimized for maximum capability without taking eyes off the road.

The holy grail seems to be the ability to text while driving. Nobody has figured this out yet. Voice to text and text to speech are just not great solutions. Add to this the fact that a million apps are used for texting and you really have a huge untapped market. Figuring this out could make someone very rich.

For the last decade I have shamelessly and exclusively used Logitech K400 keyboards for everything especially dev work.

It's that wireless media keyboard with touchpad built in you see everywhere because of how cheap it is.

I don't care that it's not clicky and mechanical or festooned with cheesy LEDs. I use vim all the time but use vscode more and work across different OS environments so I'm not anti-mouse, although since the pad is off to the side it's technically aligned with the home row :p

Anyway this thing can't be beat.
Wow, super happy for you. Just to add to this I will say that I was mis-diagnosed with an adrenal lesion which turned out to be incidentaloma. I had an adrenal gland removed however the treatment was non curative.

At the time I asked why they weren't suggesting adrenal venous sampling and was looked at like I was an idiot by the resident doctor. Turns out she was the idiot. A specialist later told me they were probably too unskilled to do the adrenal sampling.

Also the cyp11 b1/b2 PCR test has existed for ages and is in the literature. Years later I had some DNA testing and discovered I have an even rarer version of PA called Familial Type 1 caused by a non stop mutation on CYP11b1/b2, hence why the adrenalectomy did nothing.

While its rarer, the test is only a few hundred dollars. To others... a pro tip: get a pre-genetic screening test even if you aren't having kids, the cost is cheap and the result might be life changing to you TODAY.

I feel an order of magnitude better since silencing the over production of that hormone and my doctor tells me that anecdotally practitioners report patients coming out of curative surgery for nodules or on dexamethasone for type 1 often report feeling like a cloud is lifted from their mind.... I can confirm this is true.

Sadly you really do need to, push, research and be your own advocate to get the best outcomes.
I am probably a real minority but I feel like my finger skin is peeling off after long session of Apple trackpad.

They are quite convenient, but tend to only "see" generic PIDs. The manufacturer specific diagnostic codes are much more useful.

I've got one and I've got the actual manufacturer scanner, and there is a world of difference in the utility of what is reported (things like transmission oil temperature, which is needed to correctly set the transmission oil level, etc).

At some point, after taking all the other measures, adding a helmet on top of all that just seems like overkill to many people in the Netherlands.

But I understand why you might feel different. I do hope you agree that the other measures should be taken too.

Just so long as it doesn't end with people thinking that just wearing a helmet makes everything ok. It's not ok if bicycle riders and pedestrians still get run over on a regular basis.

From the abstract[0]:

Understanding how a subset of expressed genes dictates cellular phenotype is a considerable challenge owing to the large numbers of molecules involved, their combinatorics and the plethora of cellular behaviours that they determine1,2. Here we reduced this complexity by focusing on cellular organization—a key readout and driver of cell behaviour3,4—at the level of major cellular structures that represent distinct organelles and functional machines, and generated the WTC-11 hiPSC Single-Cell Image Dataset v1, which contains more than 200,000 live cells in 3D, spanning 25 key cellular structures. The scale and quality of this dataset permitted the creation of a generalizable analysis framework to convert raw image data of cells and their structures into dimensionally reduced, quantitative measurements that can be interpreted by humans, and to facilitate data exploration.

There is no speed advantage. Some argue that you should always use setf, and that setq leaks an unfortunate implementation detail. Others argue that you should use setq whenever possible, so that use of setf clearly flags the fact that something more complex is going on.
Man, ever since I started using Svelte and it became apparent to me how React has already crested the mountain and is on the downturn, I cringe so hard when I see how much work is put into React specific stuff by projects like this. I think it's going to age terribly in the next couple years.
It's a language model, it just generates text from other text it was trained on, based on a prompt. That's how you talk about it, it is a very Clever Hans.

"Why did it generate the text it did given the prompt?" is a much more interesting question anyway.

When you ask it "Are you sure", its response will be based on data from its training set adjacent to "are you sure" and other semantically similar constructs. Perhaps it has a universal bias in its data that "are you sure" will generate confidently incorrect responses.

But there's no "premise" to work backwards from, it just has been trained to respond to "are you sure" a certain way, trolley problems a certain way, and so on.
> I thought most new cars now have automatic emergency braking and many have cruise control that can bring the car all the way to a stop if the computer thinks it's necessary.

Plenty of other cars have emergency braking and have had it for years. But because those companies don't have a complete disregard for safety don't advertise "now with fully automatic braking!" and say you never have to brake yourself.

They also use technology that is actually reasonably robust and reliable: radar, lidar, etc to measure obstacle distances rather than ad hoc computer vision and wishful thinking.

> So is there anything unique to Tesla involved here just because people like to talk about the "full self driving" branding?

Because they aggressively push their "full self driving", and their car changed lane and hard braked for no reason and on its own, and their "self driving" tech has a history of driving people into walls, trucks, emergency vehicles, and from the article thousands of reports of random braking, now causing real harm.

Also dismissing "full self driving" as "branding", when the name explicitly states what it is, and they aggressively market it as being just that, and they produce fraudulent videos to act as evidence showing that it "works", is BS.

No other car company is as aggressively pushing/marketing anything it produces as self driving, and no other major car company has been making objectively fraudulent claims about their self driving ability, so of course when Tesla's unsafe self driving technology causes crashes people will talk about it.

I have never seen a non Apple device with a trackpad that is even in the same league as Apple trackpads. There's Apple and everybody else. The Lenovo ones in particular are hot garbage in comparison. Poor sensitivity, tiny surface area, low resolution, etc. Just no comparison whatsoever. The brushing thing is not an issue. Never happens for me. I brush it plenty. But never hard enough to register as a click. Of course the 'click' is not mechanical. But it does require some force. So all my clicks are 100% intentional.

The nipple thing is a stopgap solution. Most lenovo users I know have a wireless mouse that they use almost exclusively. Neither the trackpad nor the nipple thing is acceptable to them, appaently. I have a Samsung linux laptop. Same thing. The trackpad is a piece of shit so I use a logitech mouse with it. With all of my macs in the last 15 years, I never felt the need to connect any external keyboard or mouse to them. It's that good.

I actually connected an Apple Magic trackpad 2 to my Samsung laptop just to see if that makes a difference. It's great. Software support in Linux for that is fine. Silky smooth, responsive, gestures, everything. It's the trackpads in laptops that are terrible, not the software support for them. Almost universally every non Apple laptop out there has terrible trackpads. The reason I own that magic 2 trackpad is that I actually prefer using that over a mouse with my imac.

I don't think feeding those videos is a terribly hard engineering challenge for Engineers who are organized and are backed with the right financing. And who for one reason or another seem to be motivated to work almost 7 days a week.

Reddit is crap because of organizational history, and it's no a huge revenue-rich company, in a market with very high salaries.

TikTok has a a few magic ingredients, but 'dancing girls' as a starting point is one of them, the other is the learning algorithm. BTW I do not think that algorithm is magic - just good.

If you see how some Chinese companies have so many focused people and adapt so reactively to things, and they're backed by ample money.
Good point, but in audio applications for example, for cross-over filters, bipolar electrolytic caps are common. The “calibration”, if any, may be very simple, though.
You're right that there are exceptions, but I don't think this would make life for Rich people much worse. Worst case Rich countries will Annex resource rich countries, or just use predatory loans to gain control like China. As always happens, poor powerless people are the losers.

I2C bus is also exposed there: IO3 as SCL, IO13 as SDA. however, since I2C is used internally, pins should remain as I2C.

BOOT pin is also on the header, so user can override it function after the application starts. care must be taken to make sure the external periphery will not mess with the boot process.

I assume the hand capture (+ head position) doesn't give you enough to apply inverse kinematics reliably (i.e. better than VRchat), is that correct? It's a naive assumption on my part given that wrists aren't captured, but perhaps there are really smart ways to solve this. It feels like it could be a "next step" to have upper-body motion capture.

LangChain is awesome. For people not sure what it's doing, large language models (LLMs) are very powerful but they're very general. As a common example for this limitation, imagine you want your LLM to answer questions over a large corpus.

You can't pass the entire corpus into the prompt. So you might:
- preprocess the corpus by iterating over documents, splitting them into chunks, and summarizing them
- embed those chunks/summaries in some vector space
- when you get a question, search your vector space for similar chunks
- pass those chunks to the LLM in the prompt, along with your question

This ends up being a very common pattern, where you need to do some preprocessing of some information, some real-time collecting of pieces, and then an interaction with the LLM (in some cases, you might go back and forth with the LLM). For instance, code and semantic search follows a similar pattern (preprocess -> embed -> nearest-neighbors at query time -> LLM).

Langchain provides a great abstraction for composing these pieces. IMO, this sort of "prompt plumbing" is far more important than all the slick (but somewhat gimicky) "prompt engineering" examples we see.

I suspect this will get more important as the LLMs become more powerful and more integrated, requiring more data to be provided at prompt time.
Tesla is not selling emergency braking, and this is not emergency braking. They are selling "self driving cars", and this was a "self driving car" changing lanes in traffic and braking suddenly for no reason.

Emergency braking is _very_ simple tech, and is actually robust.

We have a lot of evidence that they do: the article even mentions large numbers of sudden braking complaints. For other manufacturers this has resulted in recalls, and generally is due to electrical faults rather than the computer deciding it's time to stop.

We also have a good idea of why: Tesla is notorious for favoring computer vision over lidar, and their multiple fatalities involve the camera being unable to distinguish walls, barriers, trucks, emergency vehicles, from empty road. Yet Tesla is permitted to continue selling them, with that behavior and without fixing the problems. The aforementioned unexpected/sudden braking from other companies had recalls, and those recalls were required to ensure the fault could not happen again.
