I have a document I started several years ago where I journal ideas that I come up with. There are at least two dozen ideas in it. Some of those ideas were implemented into products/services by other companies.

Seeing this play out convinced me that ideas are easy, it is execution that makes them spread. Having been able to come up with so many ideas also gave me the confidence and reassurance that I could monetize one of those ideas. Eventually, I picked an idea from that list and started my venture.

So, my advice is -- do not be bogged down by the fact that someone else arrived there first. There are thousands of product / service categories where there are multiple players in the market. It just means that the idea is valid and others also see business value in the idea. You can focus on how you can differentiate your offering in terms of features, price, geography, support and so many other dimensions, if you wish to pursue the same idea.

What would you have done if the competitor came up after you had launched?

If you strongly feel there is no point pursuing the idea, there are other ideas you could pursue for your business.

Please don't beat yourself up and get frustrated. The world is a very large place with tons of opportunities, if you look hard enough.
I would say the Chinese market is MUCH more competitive than the US market. Do a few searches for the salaries of AI/engineers. Just because Chinese companies don't operate in the US doesn't mean they are small.
Beautiful formatting and presentation, but I don't agree with trying to bolt stale design patterns from the 90s into React web apps.
Fixing the shitty bluetooth experience. Specifically, ability to disable both autoconnect and autoplay.

When my wife takes my car, when she returns the car will automatically connect to my phone even when I've already got headphones on (so my headphones will just cut out).

And sometimes I just want to go for a drive with nothing playing, but it will aggressively autoplay without asking. By aggressive I mean, even if the last thing I listened to was an album which I finished, it'll just autoplay the last song again.

Then if you want more than one device connected to the car via bluetooth, it becomes a nightmare of device management. It seems to just randomly connect to one or the other.
Any major change is going to have problems. The green revolution isn't just one event that has failed in Germany is a progressive change.
I'm not clear on what "full self driving" has to do with the article.

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. At least as of a couple years ago during the covid lull before inflation went crazy, there were new cars with this tech for barely over $20K.

So is there anything unique to Tesla involved here just because people like to talk about the "full self driving" branding? There could be, but I've failed to locate it in any of the articles about this disaster.
Why wouldn't you be comfortable?
I disagree. I think the opposite should happen.

I think that governments should make the roads so incredibly safe that helmets become (largely) redundant.

Only a couple of countries have gotten near to this goal so far, sadly (and we can still always do better).
That model also didn't have the heatpump, which is huge. It should last much longer than the gas car with a pump instead of all resistive heat.
Livebook Elixir Implementation of “How to Write a Lisp Interpreter in Python”
I have used Racket as my “go to” language a few times, perhaps for a month or two each time. For practical reasons, mostly which programming languages people are willing to pay me to use, I go back to Common Lisp or Python.

This blog material reminds me of the Beautiful Racket [1] writing system, even though it is of course different.

Yeah, I had a similar experience. I was bad at some areas no matter how hard I worked, and good at others. To me this seems like solid evidence something like “aptitude” exists. Although, it doesn’t answer questions of nature vs. nurture, whether those different skills result from different experiences earlier in life.

It's phrased badly. I can see that it sounds like it's post-processing the new clone by running spellcheck on all the commits of the cloned branch, but it definitely doesn't do that. I checked the code just to be sure and there's nothing like that in the clone code. (Unless I'm missing something, but as you said I can't fathom why it would need to do that.)

What happens is that, when you use it clone a repo it immediately shows the window for authoring a new commit message, which as I said will invoke the spell-check. That's why you are vulnerable from the moment you use git-gui to clone.
I fell for the XPS hype around 2017, when all reviews were praising those machines as the best non-Apple laptops ever made.

Turns out mine was pretty badly done, and trying hard to imitate a MacBook Air down to the motherboard, yet half of the components of my (heavily used) XPS 13 showed to be quite unreliable within just few years sadly.

Having said that, what's the most reliable, decently portable laptop around for a Linux-oriented developer? I keep hearing bad things about newer Lenovos as well

What's ridiculous about stats? A Tesla with autopilot or FSD is more than 10x less likely to be in a collision, based on various US agencies stats. Average chance of collision is 1 in 366 for every 1000 miles driven. Something like 1 in 20000 of those result in fatalities. Now, take millions of Teslas equipped with any assisted-driving tech, multiply by miles driven, include the above averages, and divide by ten. Doctors would be jelly.

Perhaps you can elaborate on what strikes you as ridiculous about fairly straightforward stats? Surprised to see you on a ML thread...
> it allows me to stop blaming myself

Absolutely. One thing I’ve found though is that it takes a long time to realize how many things there are that you’ve internalized due to ADHD.

I’ll find myself kind of falling into a rut of self loathing and think, wait, how’d I get here? What’s the root of this?

After a bit of digging over minutes, hours, or days, I come to realize such bizarre ideas have been embedded over the years that really don’t make sense. Unfortunately their effect is totally real.

Finding and dealing with these things is kind of like weeding a garden. Identifying the weeds can be difficult, and they’re all hiding in and around the cover of normal plants. Their seeds and roots keep growing back if you aren’t careful.
If you have a high mileage car and the engine blew up would you buy a brand new engine or get a used one?

On US ebay I see model 3 batteries for $5k

Nuclear definitely needs to be a larger part of our energy future. This article briefly alludes to its "social and political" challenges, but that undersells how nuclear is subject to more impact study per watt than any fossil fuel plant ever has. But the basis of that is simple economics: an economy dominated by fossil fuels (with an increasing share coming from "green" tech that will still always need a reliable base load that fossil fuels will be happy to provide) will spend large amounts of effort minimizing the benefits of a tech whose RoI to the owner is measured over tens of decades.
Lithium is one of the more common elements on this planet. It's not a rare earth mineral. And there are ways to get lithium now that don't involve boohoo stories with small children breaking their backs under inhumane circumstances. E.g. Tesla is opening a lithium refining facility in Texas. And there are several battery chemistries that don't use cobalt at all now as well. And of course you can source cobalt from reputable mines as well these days if you do need it. And many companies make an effort to do just that.

And of course batteries can be recycled and this is expected to be a big business pretty soon. Most EV manufacturers are already recycling their batteries. These things won't end up in landfills.

So, it's not the case that all batteries must involve child labor and mass pollution. There are definitely some sustainability issues around battery production of course. Can we do better? Absolutely. But it's not that horrible to begin with. And it pales in comparison to the oil and gas industry. Lots of crocodile tears get expended on behalf of the children in the Congo. But nobody ever wonders where their petrol comes from. Double standards/hypocrisy.
I believe they fixed this in the November update, though I’m not positive (I am a CarPlay user).

> “idiot in front of me slammed on their brakes at the last second while I was scanning left or right”; the system kicked in and legitimately prevented an accident.

How many accidents have you had of that type in the past, say, 300000km of driving?

Because you say it legitimately prevented an accident, but this is a routine thing that happens (drivers slam on brakes at the last second) and if you aren't routinely driving into the rear of cars who brake at the last minute, then ... no, the accident wouldn't have happened anyway.
It is sometimes far more convenient to avoid the paper trail and bureaucracy of having to provision things internally, similarly I'm sure to how renting GPUs online for short periods of time avoids the issue of having to pay for the maintenance and time costs of maintaining them onsite.

Tiny nitpick, but in my Kia (which uses the same software) the steering wheel button between next/prev track mutes CarPlay play instead of pausing it. Drives me nuts. No idea why they decided to do that. If there was a little less brick risk involved here, I’d give a fix a shot.
Honestly, just spend a few hours driving around in a Tesla. The basics (navigation, streaming, radio, garage,) are slick and work. I think if you could package something similar as an OEM and get other car manufacturers to use it...

I personally think there's a lot of room for 3rd party audio apps. I don't mind using my phone via Bluetooth / Android Auto / Car Play, but I really just want to install my streaming service's app into the car.

One thing that would be nice is, instead of a subscription for data, use my phone's data plan. Or, if you can get data cheaper, in-car wifi.

I live where wildfire is the most likely of any evacuation scenario that I can think of. I keep my pickup 3/4 full of diesel, but most of the time it is full (not a daily driver). This gives me 500 to 700 miles.

But we are talking about getting caught not full - I'm still going to have more range on a half tank than most EV have full.

If had to pick (and I guess I have) , I wouldn't pick an EV for evacuation. It is difficult to toss in a jug of electricity, but I can easily add 200 miles of range with two five gallon cans.

Now I just need some autopilot because I don't think I can stay awake for 900 miles of driving!

Lest I be framed a hater with my diesel (no rolling coal for me) truck, I think EVs have there place - just not in my area (yet).
Slaves/serfs make economic sense primarily on a plantation/manor where they can be given use of a small plot where they construct a shelter and raise their own food. They receive little or no subsidies from the planter/lord.

The difference is that serfs are attached to the manor instead of being owned by the planter. Thus, serfs are not sold, but change lords by inheritance, marriage, or other changes in land rights. Europe was so densely populated that serfs probably had little or no cash value. If you had a manor, you already had serfs.
Plenty of feedback within retina (e.g. horizontal cell modulation of photoreceptor activity) and from layer 6 of cortex to dorsal lateral geniculate to modulate transmission characteristics and suppress noise in LGN input to layer 4.
It's a difference in approach.

Some people want to mitigate your injuries in an accident. Helmets definitely stop you banging your head in an accident.

Other people feel that every accident is one too many, and want to prevent accidents outright. If you hardly have any accidents in the first place, the role of helmets is more limited.

(You should still wear a helmet if you're riding a road bike or a mountain bike or what have you, since those kinds of bikes are more dangerous. You should also consider at least wearing a helmet and taking extreme care if your local infrastructure is not (yet) designed to be safe. )
Maybe find joy in the fact that without your temporary contribution, the next step would never have started ?

I mean it's like a lot of jobs: a taxi drivers cant really pinpoint his accomplishments, a nurse will see all person they ever cure die one day, things like that.

Contrary to what someone said above, software is not a machine, it's the state reconfiguration of a machine, one of its many inputs. As a programmer all you did was align the knobs to make some inputs produce some outputs, but upstream and downstream changes will change input shape and output requirement, or the machine will change its constraints or the programmers will have figured no way to state change it.

Your contribution was important, but thanl god we dont use the state configuration you wrote 20 years ago to solve today's problems.
Hard to believe it could be some IP. Perhaps the blur is a customer or internal reference UUID that would distract us from the essence of the video.
The linked video is on a Japanese YouTube channel called Process X [1]. A couple of similar Korean channels are All Process of the World [2] and 프로세스 케이 Process K [3].

For the last couple of months, I’ve been watching a lot of these videos. It’s interesting to see how products are manufactured today. The processes range from fully automated and robotized to skilled handiwork, with most being semiautomated and including a surprising (to me) amount of what looks like low-skill hand labor.

The YouTube channels themselves are a mystery to me. It’s not clear who is making the videos or what the financial relationship is between the video producers and the factories covered. When I started watching Process X, I thought the channel might be backed by a Japanese government or industrial organization that wants to promote understanding of skilled manufacturing (monozukuri in Japanese). But normally such backing would be declared openly. Now I wondering if it’s just a small group of YouTubers doing it for the ad revenue, with the factories participating for the publicity. If anybody knows, please let us know.

In any case, the videos are very well made and fascinating to watch.

My impression is that the MacBook Air killed it. For a short time about 50% of college students were using a MacBook Air. The netbooks were tiny and awkward while the MacBook Air was larger, light weight and an elegant experience.
> while others, like those used as part of small signal filter

I wouldn't expect those to be electrolytic, though. Electrolytic capacitors are mostly used when the exact characteristics are not important, like on a supply bus, where your qualifications are typically either "at least" or "no more" than some value. Tripling capacitance usually has no negative effect on a supply bus but huge change of doing signal conditioning, so something like that is more often going to be a capacitor that is intrinsically more stable.

If it were a gender transition story, it reads more like a previous generation where therapists were more inclined to tell people to try to bury themselves in living the life of a person they’re not. And it plays out predictably in that case, in that the person not becoming who they truly are appear to be better than before, until it all comes falling apart.

But I don’t think that’s the intent of the story — I think the author did intend for this to be taken literally as a fictional tale, and it’s quite good.
How far do you anticipate needing to drive in a wildfire evacuation? I think 100 miles should be plenty to get to safety, but I guess you need to think about the next few days in wherever you are stuck.

That doesn't sound promising at all. Hourly rate for consulting should be around 2x your hourly earnings as a full time employee, so if you were getting $300K at a FAANG you should get $300/hour as a consultant. Even if you just go by your base salary (maybe your $300K FAANG compensation is $200K salary and $100K other stuff) you're still at $200/hour. There is another agency whose name I've forgotten that specializes in placing ex-FAANGsters and its rates do get up in that range.
I think building regexes is a good example of where chatgpt/copilot is useful. It’s not that it’s particularly difficult or requires much understanding, just very time consuming compared to writing an English language description and walking through an example.
> Once an economic replacement for slavery and/or indentured servitude is available, these practices tend to disappear.

Slavery is rampant in the world now. Quite a lot of it in service of the kinds of automation and productivity you describe, but in parts of the world where these discussions aren’t so casual. Slavery hasn’t been obsoleted, it’s been outsourced.

What LLMs does LangChain support?

Btw I asked chat.langchain.dev and it said:

> LangChain uses pre-trained models from Hugging Face, such as BERT, GPT-2, and XLNet. For more information, please see the Getting Started Documentation[0].

That links to a 404, but I did find the correct link[1]. Oddly that doc only mentions an OpenAI API wrapper. I couldn’t find anything about the other models from huggingface.

Yes they upgraded to RAM to 16GiB. The storage didn't need upgrading because almost everyone in engineering (maybe except designers) ssh'd to big power computers elsewhere.
True enough.

More seriously though, lifetime of a component is generally halved for each ten Kelvin increase. So idling or lightly taxing the card at, say, 60°C instead of 90°C is a 8x longer lifetime alone.
