Just to clarify that the solid-state battery still uses Lithium (but not Lithium-Ion): the article states:

> The electric vehicles being developed by Toyota will have a range more than twice the distance of a vehicle running on a conventional lithium-ion battery under the same conditions

and

> Because solid-state batteries use lithium, an element with limited global reserves, the government will assist in procuring the material.

It seems that Lithium will be the next oil crisis, especially if governments will be directly involved in the procurement...and I agree with parent, we must do better than Lithium. Perhaps good 'ol Hydrogen? (https://www.youtube.com/watch?v=sP-ZPM0nKkk)
Japan just commited to stop producing them in ~2035 [0], that means all the assembly line for OEMs will also have to pivot, so getting parts will be incredbly hard.

I'm a diehard Pajero/Montero fan and have owned several, but this year was my fixations swan song as I had to deal with the delays from COIVD but also the fact that after Nissan's acquisition of Mitsubishi meant its entire back catalog of parts were a liability and they stopped making them in Japan so they simply stopped producing them in any significant numbers for the vehicles still on the road. I can give you a long list of reasons of why that makes sense from a supply chain/logistics standpoint, but the short answer is this too will eventually happen to you car.

I worked for BMW before, and its EV program was at best a plaything, but given the amount of progress made by Tesla and now Toyota I fear you may be in a situation where they simply stop producing parts and you'll have to buy broken chassis to just be able to maintain one.

In other words, have your fun and keep it as a relic of the 20th Century, or sell it now and get some of you investment back. Get an LFA and keep low miles on it if you want to buy a Toyota that will rise in value if you want something other than a MK4 Supra, I think that will be worth way more in the future and probably sought out by Saudi Shieks as a plaything where gas will still be pennies.

Does that account for the high rates of co-morbidities associated with coronavirus deaths? I remember reading that 99% of Italian victims had co-morbidities.

In any case, I wouldn't doubt that the victims had their lives cut short by several years. The same could be said about other illnesses where most fatal cases are among the elderly, e.g. if the typical elderly victim of cancer hadn't contracted it, they would likely have lived for several more years.
I wonder if they log those searches. To be clear: in a privacy-friendly way. It would be a treasure trove to them as they basically get statistics on which searches do bad on their engine. Focus on the most '!g'd search term, and then just work down the list.
> I do think that Clojure shops (like all software shops) need to dial back the torture interviews / homework / tests

I work in three main language, including several years of Clojure work. When I applied to a new Clojure shop in Germany, the first step was a lengthy take-home assignment that was time-consuming and vague. After spending a couple days on it, I never got a reply.

A second Clojure startup in Italy did the same to me.

In both cases, there was zero guidance and it felt more like a guessing game about what they were looking for than an actual coding evaluation.

I have never experienced this in any of the other langauges I've used professionally. I've had to do simple, short technical screens, but only Clojure companies seem to expect that you give up big amounts of your time for no pay for the honor of applying to them.

That really needs to change.
Solid-state means based on some kind of crystal.

https://en.wikipedia.org/wiki/Solid-state_physics

It is not opposite to "aqueous".

E.g. "solid state relay" is a silicon alternative to an electromagnet moving a switch, both of which are devoid of liquid.
I'm in agreement with silly-silly, but I must say I spent an embarrassingly long time coding before I worked out how the REPL editor workflow worked, and nowadays I feel a bit spoiled because I really do miss it when I'm programming in another language like python. Jupyter notebooks come close, but not quite there.

The thing that really helped was watching videos of talks / tutorials of people on youtube coding something up, for example [0]. I'm not calling that one out specifically as a great tutorial, that's just an example of what I mean =)... I personally would start with an example of a form and then build it up in stages, basically tinkering with the form as I work out how I want it to function.

Another thing is that you don't have to use a particular editor etc. I'm not sure for example if you think you have to use emacs. Don't get me wrong it's a great environment, but if you're a beginner to it and clojure, that's not a good combination. Pick something you like which hopefully has a good repl plugin. There are a fair few options these days. Intellij, vscode, atom, vim among others.

Worst case if you'd like me to sit down and have a short call to go over stuff I'd be happy to set aside a little time =)... I've done tutorial stuff before and it's always nice to help someone else get comfortable in the ecosystem.

Hope that helps.

I think these have been repeated over and over again, but:

* We don't really know what the long tail of plastic in the environment looks like. It could be relatively benign, but we're painting ourselves into a corner in terms of long-term management with our current rate of plastic production.

* Plastic is a petrochemical product. Like all petrochemical products its extraction and production steps are environmentally devastating, even if the end material is relatively inert. We also like to produce it in countries with poor environmental and safety controls.

* Current policies for managing plastic waste fall into two categories: we either put it in a hole and forget about it (see the long tail point above) or we externalize it to a significantly poorer country for "recycling" (read: dumping into waterways, burning as trash, putting in their own holes in the ground). The former is an unknown, the later is bad and unsustainable.
And coming up after the break we will hear all about how water makes things wet!

It's not an x86 problem. Apple has been lapping all of its ARM competitors for a while now too.
I will say they have done good, good work. I don't think they think their specific tech fully consititutes the web: I don't think they are so delusional, mad, misguided as that. To the teams credit though, the web was doing bad. Performance was bad. Sites were bad. In way too many cases. AMP has done better. But they still need to show some modesty & humility & recognize the web is a wider thing, not their personal domain, which titles like "Web Stories" fails to show. Plenty of other folks also do excellent web.
Thank you for the response.

What I’ve heard is that plastics don’t pollute, per se, its poor waste management practices. When those practices are sufficient the plastic isn’t an issue (or is much less of an issue).

https://ourworldindata.org/plastic-pollution#where-does-our-...

The summary of those details from that document:

“However, it is the management of plastic waste that determines the risk of plastic entering the ocean. High-income countries have very effect waste management systems; mismanaged waste – and plastic that ends up in the oceans – is therefore very rare. Poor waste management across many middle- and low-income countries means that these are the main sources of global ocean plastic pollution
This makes the improvement of waste management systems across the world critical to reducing plastic pollution.
An estimated 20 percent of all plastic waste in the oceans comes from marine sources. In some regions, marine sources dominate: More than half of plastics in the Great Pacific Garbage Patch (GPGP) come from fishing nets, ropes and lines”.

If this is true, then the best way to address the pollution would be to address those poor practices.
Your body and brain are a collection of cells. None of those cells are what we would call intelligent on their own. Intelligence is an emergent property of a system of cells. Ant and bee colonies act as superorganisms (since they all depend on their queen for reproduction) and therefore the apparent intelligence emerges at that social level.

>Uber’s advocating on behalf of workers comes amid an ongoing battle around how to classify rideshare drivers and delivery workers. Uber has long argued that its workers are not employees, while many gig workers have argued they are misclassified as independent contractors and should be entitled to the many labor rights that come with the employee classification.

"Advocacy" to keep your worker bees operational is clearly not without a double-ended motive. But it's true, they do enable many people to get home with a paycheck.
Crazy and sad to me that THIS is what motivates you to advocate for cryptocurrency. Underbanked? Sure. Government turmoil and inflation? Yep. Sex trafficing 13 year olds. Na, probably shouldn't be allowed to profit off of that. Take that stuff off and all good, you're back to taking payments. ezpz. If those "gatekeepers" are literally saving lives, I'm all for it.

> Look at what Democrats said just this year. Nadler asserted that if he wasn’t impeached, Trump would “rig the 2020 election.”

How can you possibly say this is mere paranoia in the face of an active, ongoing attempt by both the President and a huge portion of the institutional GOP to do exactly that?
You have obviously never been in such a situation.

I didn't grow up poor, but did have some time in my life when I was destitute, homeless and without prospects.

I'll tell you a few things about that:

1. It's hard to hold a job when you have no place to shower or keep your belongings;

2. Homeless shelters are frightening, dangerous places and many (myself included) preferred to sleep rough than risk their lives in one of those places;

3. Food banks/Soup kitchens, etc. are few and far between. I shoplifted and ate out of garbage cans when I had to do so;

4. If you have no fixed address or documentation, it's hard to get stuff like food stamps or other assistance.

It's been 35 years since I was in that situation, but it's an experience I will never forget. No one should be put in that situation. Ever.

You have no idea what it is to be penniless and homeless. And for your sake, I hope you never have to learn the hard way.

Unfortunately, because of the callous, calculating disregard of the US Senate, many folks in the US have and many more will learn the lessons I did.

More's the pity.
Why do we need to get off Lithium its an abundant mineral. If its about dirty mining there is not guarantee other minerals will be mined cleanly either.
> As a consequence of all these problems, there began to be a growing movement across all levels of the org that was rallying around the idea of “rewriting the app from scratch” The general sentiment was that the architecture was slowing us down, starting over would be faster.

I've read plenty of these stories where a rewrite was a total disaster. (Most famously, Netscape.) I've seen and/or lived through some too. (One where a major distributed system was completely changing its storage model, and it was thought refactoring was impossible. In hindsight, it was achievable and would have saved _years_.)

Anyone have examples of regretting a refactoring to the same extent?

I think it's easy to underestimate how much difference (1) makes. Take the famous line "thequickbrownfoxjumpsoverthelazydog" - and think how you'd parse that out programatically. You'd start at the start, reading each character in, comparing it against a dictionary, and when you decide you have a whole word - then you can split that word out - and then continue on to the next.

But you can't really do this in parallel as the start for each word depends on the previous split already being known.

If it was simply law that every word in existence was 5 characters, you could parse this out with zero lookups, zero knowledge. "accurately" isn't so much the issue, it's that you have to decode each instruction to know where the next starts.
I was a bit incredulous of the premise of the article, but I decided to pull Spotify open and see how this "roam-and-graze" experience treated me. Overall what I came away with was that there are a ton of podcasts about subjects I'm interested in, but not a lot of them look that interesting. Perhaps because it's Spotify, all my recommendations were music-adjacent. There were a couple episodes with interviewing musicians I like who don't do a ton of press, so I added those to my episode queue, but overall I was mostly amazed at how much content there is that didn't seem interesting to me at all.

Sort of reminds me of 15 years ago or so when it seemed like everyone had a blog (or two). Tons of content, but a whole lot of it not that interesting. In the end I ended up keeping the RSS reader and focusing on feeds that consistently delivered content I liked and I "graze" from there. Interestingly, this is essentially what I do with Podcasts.
I think you raise a valid point, which is that thermal exchange management is a significant issue for fast charging batteries, regardless of capacity. However, Tesla already has deployed 250,000 watt chargers in real world use, so a jump to the 450,000 watt range is within an order of magnitude, and so wouldn't be inconceivable.
Sorry if my above comment sounded like gate-keeping, that was not my intention! One of Clojure's biggest downsides IMO is the barrier to entry, with the relatively complex tooling setup being one barrier. I wrote Clojure for a long time before I finally had a powerful tooling environment, and I wish I'd discovered it sooner.

Your specific setup will depend on your primary editor. For emacs, the go-to is https://cider.mx/. E.g., with my cursor beside an s-expression, I can hit a couple keys to evaluate and view the output. Don't give up!
Does anyone still use podcatchers? I've been using stitcher for podcasts for a super long time, and found podcatchers pretty annoying throughout time. The only use case I could conceive is storing a podcast to listen on my apple watch.

Though I am hardly a "pro" podcast listener. I guess my question is, are podcatchers already dead? And if not, who uses them?

Migadu is awesome. And way too cheap.
Air is a pretty bad thermal conductor.

An average ICE is only producing 200HP at a specific RPM, for short period of time. Red-lining any sedan while being stationary will probably overheat the engine pretty quickly, as the on-board radiator fan either electric or mechanical will not provide enough airflow. They are designed to be cooled by incoming air while driving.
> people thinking that they need to own 10 properties as an investment

I wonder what would happen if housing were not an investment but construction would be legalized that turned housing into a commodity. Right now many attractive cities are often captured by home owners who collude against against new housing because that pushes prices down.

I hope the company that comes after Airbnb disrupts the construction industry, allowing cheap but high quality housing for everyone, and not just anywhere but in places of demand.

Volkswagen will be using it eventually.
It exists and is called Powershell
I'd add a option to "rent & option to buy". It goes both ways: I have a pricey guitar lying around that I haven't used for 2year+, but haven't come around to quite sell it (because I might one day pick it up again, as I used to be very good at it). It could be quite a great thing to rent to young music students (like I used to be) that want a fairly good sounding guitar. Some years down the line having the option to just sell it might be nice for both.

The real added value is like the instruments above: you want something for a couple of years, and there's quite a lot of people out there that already own it (and is past year of using it). Although, second-hand shop already covers this usage, by people buying (console, instruments etc) it and using it for the years, and then re-sell it on second-hand. It only covers certain products so you might find a niche, maybe.

I'd say the most usefulness in the idea is what I see as a local problem around me:

I live in Tokyo right now, for work, so I wont stay here 1-2years+. There's a lot of people like this in Tokyo, it's often called "a transit city" by expats. Furnished apartments here is a thing, but its quite expensive and limited. For someone newly arrived, just renting the furniture might be a useful option. (but I don't quite see who would only rent furniture, since storage is a problem while not being rented)
Nah, that was years before the WWW (as we used to call it). Those were walled garden networks (CompuServe was another one), which eventually offered connectivity to the Internet too (and not long thereafter either ceased to exist or converted to Internet service provider and/or web services).

Not only has DDG become better, especially for regional/localized searches, Google has become worse.

What Google has done is to prioritize mainstream sources over correct matches. In the old days you could get a match for small unknown blog on the first page, today it is very rare for me that I get that. It is usually mainstream sources on the first page, except when the search is very technical like programming.

This becomes even more apparent for Google’s affiliate YouTube where you can search for the exact title and it doesn’t show up on the first page. Related videos is also broken.

What drives clicks on YouTube today is the very curated home page for a user. This was not how YouTube used to work.

These factors has changed how we, at least for me, consume content. In the old days you found small independent sources much more easily, which meant that it was up to you to make a judgment if that source was interesting or not. Today it is the opposite, "here is a clip that has been viewed 20 millions times before you, enjoy!". This has made the web much worse.

One thing that Google do better is grouping result from same source, like here is all matches from Reddit, this has two main benefits. First it easy to view that group separately. Second is that you can view more matches on the first search page.
I got into php in the very beginning. Kept learning everything else but found the limitations a fun challenge and being able to rapidly produce something kind of works with my matra of wanting to do a bit of everything.

I started with C/C++ so php was natural fit.

A good question would be if starting out today what language would I pick?

I'm tempted to pick php but I would probably go for react. The market is huge career-wise, the language is fun to develop in and the community is strong.
"Other option is to start my own company"

You throw that in at the last minute. You either want to start your own company or you don't. Most likely don't, since if you wanted to you already would have.

So yeah, go job hunting. You like the job but want more money so go see if anyone will pay you more money to do what you do now.

Most developers check that stuff out every week.
450 kilowatts is about 600 horsepower or so. That's a lot, but it's in the range of the sort of power that a high-end electric car motor might draw now, and they somehow manage it with not-too-unreasonably-thick electric cabling. Granted, there probably aren't many electric cars designed to output 600 horsepower for ten minutes: eventually, the cables and the batteries will just get too hot.

I'm not an electrical engineer; I don't know what the proper cable size is for this application with all the correct safety margins, but it doesn't seem too terribly unreasonable as long as the voltages are pretty high and the battery can tolerate it. If heat is a problem, then water cooled cables can help.
I use mailbox.org. They offer encryption and I believe have a focus on privacy. best part is 1 euro a month, but that is for their basic package which I think should be enough for most people.

The context of the discussion is ramen profitability and potential very early investment (angels, yc, etc.), and the commenter seemed to be looking for an inexpensive place to live.

Early start ups are typically going from zero to one, so they really need to find a small and passionate customer base somewhere. As many folks have said before, often times it makes sense to do things that don’t scale early. This might mean in-person visits. YC has many stories of this working, like Airbnb and Stripe.

I will also add that if you are looking to go down the VC path, being near VCs is important. You can raise VC being far away, but it is more difficult, and the associated costs will eat away at what the original commenter seems to be looking for, which is a cheap place to live.
