> If we can get these chips manufactured at a reasonable cost it would really help EVs get longer range.

How much longer though?

The motors that move the wheels consume way more energy than the microchips on board the car. Even when a car is standing still, the AC or the heating system are also quite energy-hungry compared to a few CPUs.
New Yorker and Brain Pickings.
Quanta is great for math-y stuff.

Also, I try not to read too much online. Like you say, so much is junk.

And I limit news. There's a real negative cognitive and emotional impact from reading so much depressing stuff about which you can do so little.
The link says you should not use the autotype, but use the browser password manager instead.
It always suprises me how people don't do minimum effort for hiding this stuff.

And no one notices.

Do scientists actually read what they cite?
FWIW, what they were accused of was squatting, not protesting climate change. I still think that's a ludicrous abuse of police powers, but it's worth being accurate.
The shavers which are considered to be used also in the shower have running on power line disabled.

> Honestly, SQL has this problem too, but it presents itself not in the way you store, but in the way you query. There are simple schemas and complex ones, and irrespective of that there are obvious query sets and unplanned ones (i.e. written at runtime as part of the data analysis process). SQL and its autoplanning is required only for complex+unplanned cases, in my opinion. In all other cases I know my data and I’d better walk through the indexes myself rather than writing 4-story queries to satisfy the planner. At the end of the day, nested loops through the indexes is what RDBMS does. There is no declarative magic at the fetch-and-iterate level.

The thing is that what worked at specific time can change. For example if you have simple join with two tables, let say A and B. You search by column in target A to get value from column in table B. Now if both tables are large then it makes sense to lookup in A by an index, then use foreign key and index to find the row in table B.

Now if A and B have few elements. Even if there is an index on both of them, it actually is faster just to scan one or both tables.

It might be actually more beneficial to ensure that tables are properly analyzed, have right indices and preferences in the query planner are tuned.

If you need to override query planner, you don't have to make sophisticated queries, you can just use this[1] extension. Though if things aren't working right it is either lack of data, mis-configuration or a bug.

So if our workspace environments are fully reproducible and trivial to deploy already, what additional benefits do these services bring to the table? (circling back to my original question :) )

Been using internally-managed reproducible environments for a while now, so I'm fully aware of the major benefits.

Will have to look into Gitpod more, thanks!

You're the second person in the thread who has sought to diminish the point by tangentially invoking the controversial aspects of what they do. It's a non-sequitur. I'm not engaging with that part further, as I responded to it here: https://news.ycombinator.com/item?id=28425675

As for financial losses, yes of course the pandemic year was hard, but it's completely false to say that Airbnb has never been profitable or that it is not a financially strong company. Indeed they have financial strength built into the foundations of the company; they were revenue-focused and profitable in their first few months, and the very thing that made them attractive to investors was that their unit economics (dollar margin per transaction) was so strong. And they have had several profitable periods in the years leading up to their IPO. Yes they may have ended up posting losses, because they've spent heavily on marketing/growth and expansion into new product categories, but that doesn't make them a weak company, quite the opposite. If you're trying to equate them to money-sinks like Theranos, WeWork, Uber, etc, you're mistaken; they are the very antithesis of those kinds of companies.
They are generally exposed through a proxy that sits in between. If you don't authenticate, you can't send a request to it at all.

(This is opposed to the lazy model, where your aplication is fully exposed to the web and you click log in and it redirects to SSO - if there is a vulnerability that doesn't require authentication you're already compromised)

The proxy will handle sign in and passes traffic to/from the webserver backend, and you should not be able to send a single HTTP request to the underlying application without the proxy capturing authentication and who the user that sent the request was.
I'm not a transportation or tech expert, but the idea that detailing in law the protection of user data will somehow make it come true is absurd. This said, not sure what the alternative is.

From the article:
One challenge may be convincing drivers there’s a benefit to installing a mileage tracking system in their vehicle and easing any privacy concerns about the device creating a data trail showing where they’ve been. The state work group recommends giving users the option of using either a GPS or non-GPS tracking system and shoring up data protection laws to safeguard any location-based information, similar to an existing law that shields information on vehicles passing through tolls.

“Legislation passed to protect this data can be tailored to address when and how the information can be shared and used and can increase customer confidence that personal information is protected,” the interim report says. “Confidence in the protection of the data generated may enhance customer willingness to participate in the program.”

Jonathan Gifford, director of the Center for Transportation Public-Private Partnership Policy at George Mason University, said the privacy issue is “a live one” but he thinks it can be resolved by giving users options about how their mileage is tracked and what happens to their data.

“Some of the options out there do have a device that is plugged into your car’s data port and keeps track of when and where you drive but it doesn’t share that information,” he said. “It’s sort of a tracking device but it doesn’t share the data.”
Probably because they’re on a mobile device or essentially monitoring 24/7 would be my guess.
Doesn't explain apple's Mouse

Probably a security measure to prevent people from using the shaver in the bathroom, while it's connected to the power outlet.
One quick points: 1.90$ is arbitrary as a mesure of absolute poverty. It is way too low. And actually, the best way of mesuring poverty is: %people sleeping without a shelter and %people having nutritional deficiency.

Having said that, i think some economist tried to do a correlation between adjusted dollar income to lifespan, and found that for each cent you make until you earn at least 5$ (adjusted) a day in industrialized/globalized countries, your lifespan at 5 is growing pretty fast. after this, the gains are minimal, so the actual limit on poverty should be 5$.

Excluding China, the %age of the world population under 5$ (adjusted) is diminishing since the 70s, as income from capital outperform income from labor faster than the marginal productivity increases (AKA: Piketty was wrong in his book Capital in the 20th century, capital did not take all productivity gains, it took more than that).

I do not have an opinion on degrowth, i hope it won't happen in my lifetime (because i'm an hypocrite, but at least i'm not hiding between either Singer/Gate optimism or other techno-optimism), i'm not actually convinced we will manage to avoid one, and i think a controlled one will be better than one that id forced upon us.
With the way charging circuits go these days, I can imagine heat to be another reason to stop these devices from both charging and operating from battery at the same time (sure, it should be easy to make a pass-through, but phones don't).

With most adapters being at the wall, and a DC small-voltage current coming to the shaver, the risk of electrocution should be small, but I am sure we'd see people dragging extension cords with them into their showers, so that's a pretty reasonable safety measure too!
There is still plenty to be gained from squeezing that last 1% out. Tesla is probably cell limited right now, so if your car is 1pct more efficient you can pull less cells in it and mthen make 1pct more vehicles.
Heya, Geoff from Gitpod here. From Gitpod's values at https://www.notion.so/gitpod/Brand-Values-2ed4c2f93c84499b98...

> We are not opinionated. We integrate, don't dictate. Gitpod is an open platform giving developers full transparency over how Gitpod works and allowing everybody to contribute. Our product design integrates with all stacks giving developers full flexibility. We seek to collaborate and partner with other products/companies that share these values.

> Working in open source is in our DNA and everything we’ve created over the past 10 years was built in the open. For Gitpod to be successful we have to win the hearts and minds of developers. Developers (everybody in our team included) enjoy discovering, installing, fiddling around with, contributing to and talking about open source software. This makes open source in the developer tools world unrivalled as a go to developer strategy in terms of speed, cost effectiveness and level of adoption it drives.

Both GitHub Codespaces and Gitpod are _wonderful_ products that solve big problems (https://www.gitpod.io/blog/workshops-as-code) in our industry. I strongly advocate for people to build with portability in mind and to not lock into proprietary solutions. See previous comments by myself on this page for some the possibilities (nix/docker-compose) and how it's possible to share between local, gitpod and codespaces the same source tree. <3

The story is not really about Apple Mouse, it's mostly mentioned tongue-in-cheek about comparable design traits and the backstory of how Apple design was influenced by Braun.
The Philips electric shavers do this too. They do not work while being charged and need up to 12 hours of charging for 30 minutes of operating time.

However, there are some “modern” shavers available now from Philips which offer 60 minutes of shaving with a 90 minutes charge time, so there is hope yet.
Primo RX8 mini, a smarthone with physically disconnectable microphone and camera
My employer was bit by this on Wednesday. Thankfully we had Crowdstrike on it which blocked any real damage. But it definitely moved our cloud migration from “later this year” to “later this month”.

Also, not having confluence for a day exposed just how reliant we were on it for day-to-day activities.

This at the end was a brilliant and very sharp comment:

"At its core, I feel like degrowth’s appeal comes from its implicit promise to recast genteel North European decline as some sort of grandiose world-saving moral quest. "
> Fundamentally exponential growth is not sustainable in the long run.

Growth doesn’t mean that we make materially more things, but that we make better things. Compared to a torch, a calculator, a phone, a GameBoy, etc… an iPhone requires far less raw materials.
This can be applied to any industry, so exponential growth is indeed possible.

We don’t need to work more or consume more things unless we either give up on innovation or if we think innovation is not possible because we have reached a knowledge boundary. The former would be a silly decision to make, the latter is an assumption that should be demonstrated.
Vaccine Passport Missteps We Should Not Repeat
We are going to 'degrowth' and those on the 'bottom' are going to suffer the most.

If not voluntary, then forced. The ecosystem that carries all the growth is rapidly falling apart (relatively, with speed measured in decennia, generations or centuries). We cannot stay on the exponential paths we've taken the last 250 years for another 250 years, that is impossible. Let alone for another 2500 years
I think this is probably it. Life + death safety is going to trump usability every time.

Meanwhile the Apple Mouse thing was (I presume) Johnny Ive & his obsessions getting in the way of real world usability. I don’t think anyone is going to die if they use an Apple mouse whilst it’s plugged into a usb port!

Why nuclear reactors are getting smaller
There's a well-defined political argument called degrowth, which says that we need to stop economic growth in order to save the planet. There are some people who put forward this argument. Noah Smith is arguing against them. I think it would be hard to do this without giving them a collective name.
But `foo()?"A context message for a human".bar();` is even better. Currently, we must use anyhow's `foo().context("Message")?.bar()` [1] for that.

They are referring to the privacy of _other_ users whose information could be scraped by these plugins, contrary to the privacy guarantees of their post (e.g. "only my friends can see this"). I'm sceptical of Facebook's motivations, but we should at least be accurate.
The article is handwavy about this, but states that outsourcing is included.
I doesn't need a login from me. Would be pretty bad if they would, no love for instagithub.
I'm not a degrowther (though I do think we should try to make our economy more symbiotic with nature where possible) but a couple of issues here stand out to me:

does his argument that Western countries' use of resource has started to inversely correlate with QoL improvement hold up in the face of those same countries outsourcing almost all manufacturing to other countries? It's all well and good that the US' use of metals is decreasing, but if that's just because China is using the raw materials and shipping the final products over then that's no better.

He also makes the argument that as non-industrialised countries begin to industrialise, they can just make use of non-material goods like we do. Is this not based on the assumption that other countries won't want similar standards of living to the US, ie car ownership, disposable and consumption goods, etc? We're talking about a multiplication of the production of goods.

From a systems standpoint, I think we need to be doing 2 things (for CO2 specifically, that's far from the only concern): reversing the increase of carbon in the carbon cycle (ie, reducing dependence on fossil fuels and sequestering carbon artificially if/where safe), and monitoring and increasing the bandwidth of the decarbonisation phase of the carbon cycle (soil, trees and the ocean playing the main role).
I think the deeper point is that sci-fi is often just X in space. So pirates or cowboys or Vietnam or cold war or colonialism or communism or murder-mystery in space.

We already have stories and/or history that fit that model, and you can reference back to those to understand what's going on.

But that inevitably leads to absurdity at the edges of the metaphor. And those clichéd bits of absurdity become the standard tropes that you can either go along with and celebrate and/or rebel against.

Personally once I get into a genre, I then gravitate to the examples that play with or subvert the form. Doesn't make them better or worse, but since I've already read a lot of the other stuff I'm ready for that next step to keep things interesting.
What would happen if all guns disappeared?
Yeah but in most EVs you need to transform the battery DC current to AC for the motor.
I agree, it's impossible to look at a country alone in a world economy.

Claiming that services like social media do not rely on higher consumption of raw materials is really far fetch. Good luck building growing a service like Facebook without:
- growing mobile phone market
- growing mobile network market
- growing internet access
- growing your servers behind it
- the energy consumption associated with it

It's quite easy to ignore facts when omitting that the majority of the supply chain and user base behind that is not located in the US.
I'm fairly confident that adding those numbers to those charts will give a different picture indeed
This seems not to address the arguments made in the article - for example, that economic growth, beyond a certain point, is mostly about "doing more with less". Maybe those arguments are wrong, but they need responding to.
I've been using i3 for a few years now. I wouldn't go back to a non-tiling window manager at this point. Initially I was drawn to stumpwm [0] because it's built with Common Lisp and therefore very hackable. There is also exwm [1] which uses emacs, but I haven't tried it.

In practice, though, I've found that I rarely want to write any hacks for i3 itself. But this article is very cool and I may use some of this stuff. The one thing I have spent some time on is my i3blocks config which has some things I like such as CPU/RAM usage monitors and ability to control pulseaudio (switch outputs, control volume etc.).

I use i3 at work but for more than a year now at home I've been using sway. I've had a few bugs with Firefox on Wayland, but currently it's all working very well. Sway is excellent.

I know you’re right, but I often wonder what would initiate change.

Anecdotally, I quickly tire from reading or hearing arguments full of the polarization labels (liberal/conservative/neocon/neoliberal/etc). Wonder if I’m alone in this.
Tired of filling out copies of the same PDF forms by hand every day?
I'm not a user, but I have experience with one use-case where I'd imagine they're very useful:

When maintaining an open source project, there's often a little bit of tension between making the development experience more productive for you, the maintainer, and more convenient for new contributors. Using a more complex toolchain might make things nicer for you as someone who works in the codebase every day, but adds overhead to anyone who just wants to make a single contribution related to their own work. I could imagine having a "click here to develop" option would help ease that tension.
A 1 ton rod would loose most of it’s kinetic energy on reintry.

“A system described in the 2003 United States Air Force report[9] was that of 20-foot-long (6.1 m), 1-foot-diameter (0.30 m) tungsten rods that are satellite-controlled and have global strike capability, with impact speeds of Mach 10.“

That’s 1.725m2 of tungsten at 19,280kg/m2 = 33.2 metric tons and it’s still only doing Mach 10 on impact.
Unless the Forced Green Growth is redistributive in nature the policy Noah is pining for will actually result in the exact same outcome for the poor as degrowth. This is obvious when you consider who owns Teslas cars or who has transformed their roofs to solar.
Oh yes, I also had a couple of such design - used an app or a server, ssh connection or simple websockets. But for this one I really wanted it to work standalone !

Is this really true? All those objects are fairly low tech, between the lifetime of a torch or calculator which is way longer than the one of an iphone and the simpler production process behind it, I wouldn't be surprised that producing an iphone requires more materials, generates more defects for one working device and requires an way more complex supply chain.
