It looks like nobody learned the lessons of Juicero.

Spending millions of dollars to create special-purpose robots that can make a grain bowl that can trivially be prepared by humans. The cost of the robot would exceed multiple years of annual salaries for a full restaurant of this nature. And you didn't even manage to eliminate the need for human employees: you still need employees to maintain and service the machine, to clean up the facilities, to stand by when the machine fails, and to drive the robots around. And those employees will also be more specialized, and thus more expensive to pay, then the cheap line workers they would theoretically be replacing. Plus, there's the central food kitchen where humans would be doing the bulk of the actual food prep work.

Your other statements support the idea that you guys don't actually know how restaurants (or restaurateurs) work, and you're acting like being Stanford grad students gives you some sort of amazing insight that nobody else in the restaurant industry has thought of before, like digital signage (which every new restaurant in the past few years already uses), or using food trucks in parking lots to avoid paying for rent (food trucks have been around for a decade), or partnering with restaurant chains and chefs (few if any of whom would partner with you because it would irrevocably damage their brands). And let's ignore the magically fuzzy math on how a special purpose grain bowl robot is somehow cheaper than spending 5 minutes on training somebody to put grains, then toppings, then sauce, or how spending millions on robots up-front before the restaurant succeeds is somehow financially more prudent then paying for labor costs on an operational basis where said labor can be increased or reduced as necessary.

Like most restaurant chains, we do the bulk of our prep in a central kitchen
Yes, fast food restaurant chains do this. Not salad chains, because there's a limited shelf life for freshness once you prepare grains and greens. It's measured in minutes. Nobody wants to eat limp greens or stale grains. You've basically just stated that your food will never be fresh, and that's an absolute restaurant killer in the healthy food space.

eventually develop multiple concepts so each auto-kitchen rotates to a new menu on a regular cadence.
Many restaurants have launched with this idea. Few stick with it, because food waste is the second biggest controllable expense after labor costs. Changing the menu regularly means more food waste.

So, all in all, you've just created a business model doomed to failure: high startup costs, high operational costs, high prices or unrealistic VC-funded below-market pricing, and stale food. This might work in the Bay Area, but it won't take off anywhere else.

My advice would be to pivot away from this "special purpose" grain bowl maker and make something useful. Like a general purpose arm that can do everything a human chef could do. That would be valuable.
It's hard to compare because it depends on you and policy.

Unless you have unusually high W-2 income, expensive or large property, etc most of the differences between states are pretty marginal when you net everything out.

Many of the "low tax" states have a catch, whether it be sales tax on food, school funding, high property taxes, local governance that encourages HOA, etc. At the end of the day, it doesn't really matter too much. People complaining about taxes is background radiation.

I use it with Fedora happily, and for work I have to use Zoom daily. I did have to replace a fan with one from Aliexpress due to rattle, but haven’t had issues since.
Not sure how this came back around into the zeitgeist today, but this is my post from awhile back. Thanks to all who had nice things to say about it.

I'm definitely an amateur mathematician, though I tried my best to write the post like I think I'd try to write a proof. It came about because I stumbled across the equation, but I did not know _why_ it worked, so I was semi-obsessed with figuring out the _why_ for a long time.

I have nothing else to promote, haven't even put anything on the site since this one and only post... Anyways, thanks, news-YC.
Do you think that you spending 0% of your time managing iOS devices has something to do with apps not being able to use their own payment system?
If Apple was kicked out of China, leaving them with no Chinese manufacturing... ? In that case the shareholders have no option, it's either that or sell no new devices.

If you mean that the shareholders would rather please the Chinese government, rather than risk getting kicked out of China, then yes, I think Apple would go a long way to not piss off China.
This seems to be where they explain it:

"Even though Librem Tunnel is just part of the overall Librem One offering, because it’s part of a subscription service, Apple is requiring us to add the ability to sign up and pay for Librem One subscriptions within the Librem Tunnel app before they will allow updated versions into the App Store."

However, what you show seems to contradict that?

EDIT: If I were to guess, the flagging was an automated process, i.e. Apple flagged it and sent an automated email to Purism. Whether or not Purism tried to respond or not I do not know, but in the end they decided not to deal with it and pulled their app.
> “We’ve proven that under ultrasound excitation the coronavirus shell and spikes will vibrate, and the amplitude of that vibration will be very large, producing strains that could break certain parts of the virus, doing visible damage to the outer shell and possibly invisible damage to the RNA inside,” says Tomasz Wierzbicki, professor of applied mechanics at MIT.

Why say they have proven it, when all they have done is a simulation and they have not demonstrated anything? It seems like they have a hypothesis, not that they have "proven" anything.

Fully agree. But thinking such a way is shortermism on the behalf of capitalists. I think we need to do more to encourage longtermism across the whole populace. Things like capital gains tax favorability is one example of such a help.
> The risk isn't worth it at this time.

This pandemic was never about the risk to this cohort that continues to be brought up. The point is that taking the vaccines reduces deaths. In places where these vaccines have been deployed widely, you cannot refute that statement. Just because the people who are dying don’t look like you does not diminish the utility of the vaccine.

I’m so tired of hearing that young people shouldn’t take the risk of vaccines because the risk to them of the virus is less. That is not why anyone at all is urging you to get the vaccine, or why we did any of this at all for a year.

A society is built on mutual trust and actions and speech like this shatter it; the selfish arguments seem to know no bounds in this pandemic. I did not sit in my damned house for a year because I was afraid for my own safety!

Furthermore, The article linked claims PCR testing isn’t good enough for efficacy and from what I understood had nothing to do with safety at all. In fact, the title of that submission includes “... REGARDING CONFIRMATION OF EFFICACY” and no mention of safety, but maybe I’m not “well-versed in science” enough to understand it. Thank you for talking down to me though, we would not want me to leave this conversation with a sense of self worth.

It seems to me like you’re unintentionally spreading disinformation. I assume you don’t want to be doing that, so you should probably check your priors here, as they seem to be outdated.

Products low on the value chain that are unskilled-labor intensive are almost universally cheaper abroad. It wouldn't make economic sense to make t shirts in the US unless consumers paid a premium.

Products high up on the value chain - the kind you don't dress up in your best slacks to go and buy at Walmart are a different story, however.

I can count several software projects that were outsourced off the top of my head that were ostensibly done for cost savings purposes and were utter disasters. These disasters are routinely covered up and bullshitted, too.

This has at the same time not dampened the appetite for outsourcing software much. Coordination (i.e. management) costs are higher. Consulting companies can bill millions for these projects.

This is the point the article was making - pretty cogently.

It's less of a smoke-filled room conspiracy and more of a mundane "conspiracy" to shape the supply/demand curve.
Uh. Sure
For posterity, NREL's number is $ 0.47 / W for utility scale solar. It's not $ 0.30 /W and there's no way a speciality cell is cheaper than utility scale cells.

They come close in number of ports and battery life *but* they still have an excessively big touchpad, don't have a 13 inch version and start at 1.7 kilos (which makes them less than ideal for carrying around).

But I agree they are the very nice machines and we keep a bunch of them in the lab.

I am sceptical. At least around here I strongly doubt that it'd even be legal to run that thing (or several of those things) across the pavement. Pavements are for walking, prams, wheelchairs and whatnot that would be obstructed. I might be wrong there though.

I'm not arguing against the idea that such infrastructure would be good. I'm just saying that a private person renting an apartment in a city can not reasonably be expected to slap solar panels on the roof of the building they don't own, illegally run cables over the pavement they don't own to their cars that may or may not be possible to park near the building they live in.

To them, a car that "charges itself", even significantly less efficiently, may indeed be a better solution.

We thought a lot about correlated storage failures - especially with regard to SSDs - as we rebuilt our infrastructure circa 2012/2013.

In the end, the low hanging fruit - or, the biggest actionable takeaway - was that when we build boot mirrors out of SSDs, they should not be identical SSDs.

This was a hunch I had, personally, and I think experience and, now, results like these, bear it out.

Consider: an SSD can fail in a logical way. Not because of physical stress or mechanical wear, which has all kinds of random noise in the results - but due to a particular sequence of usage. If the two SSDs are mirrored, it is possible that they receive identical usage sequences over their lifetime.

... which means they can fail identically - perhaps simultaneously.

Nothing fancy or interesting about the solution: all rsync.net storage arrays have boot mirrors that mix either the current generation Intel SSD with the previous generation Intel SSD or mix an Intel SSD with a Samsung SSD.
> 2. “These pre-installed apps will also be deletable after setup is complete, just like any other third-party app that is downloaded from the App Store.”

They aren't even preinstalled. You get a prompt during setup and they're pre-selected to be installed after setup, but you can uncheck them.

"All apps in the list are pre-selected to be installed as part of setup; however, users are able to deselect apps individually if they don’t want them."
thanks. yeah a lot of angst and resentment here. I was truly naïve when I came to CA/adulthood. I thought.. wow. Kool stuff interesting people, best ideas. To my disappointment, behind the curtains were very manipulative very very small boy's club. If you want to see something realistic, watch the fictionalized docudrama: The Social Network starting at time 9:00mins The ivy league clueless boys have the connections, coders have the idea/product/dedication to their craft however clueless. What zuck got right was the right mentors who also happen to make an accidental killing. Just truly sad how things work. No diff in any industry however.

There was one partnership that did work. Primarily I suspect due to lack of "Ivy league" connections: Steve Jobs/Woz. Two very naïve but smart people lacking the not yet tainted by the ivy leaguers created an empire built on good foundation. Albeit Jobs could have been nicer ;) I worked in his environment and he was scary as you see him on shows dramatized or not. Met him in hallways/cafe.. he never ever smiled but did worship him. He knew what to steal, how to exploit then productize to make people happy. Honestly, 90% of the products he facilitated would never have seen the light of day. Case and point: Xerox's mouse and desktop.
Great point. If you've never had an ultrasound, it's safe enough that the technician doing them (who may see dozens of patients in a day) isn't even wearing any shielding or protection.
Beamo is local only through USB, I may or may not have been tempted to buy it just for that.

Or, if the parent is correct, the rest of the world will never catch up - because the US will keep adding regulations to keep itself more expensive.
Assembled is a great product. I have recommended it to a bunch of people that are serious about optimizing response times and getting the right people in front of the customers.
It's all fun and games until your next whale of a customer asks for your SOC report. Then the auditors are asking you to prove you've audited your code and dependencies. They ask "who has access to customer data? Who can deploy code? What about your perimeter security and intrusion detection? Are you running virus scanners on all of your servers?"

Then you realize it's easier to have a complex deploy pipeline that does all this stuff that isn't just writing your app for you. And containers are a decent enough way to abstract your app away from all the cruft.

I guess the answer is don't write enterprise software?
If artists got a penny per stream, I'd create one song and set it up on repeat 24/7.

365 days * 24 hours * 60 minutes = 525600 minutes
525600 / 3 minute song = 175200 streams
175200 pennies / 100 = $1752

So I could pay 120 bucks a year and make 1752! I like the sound of that! And with the family plan, I could pay 1.5x the cost a month but get 5x the revenue!
I think the new EU right to repair laws require appliances to be repairable for up to ten years, this article at least seems to suggest that the intention is for a level of ease of repair especially in regards to fasteners and fittings:

> Under the new EU rules, manufacturers will have to ensure parts are available for up to a decade, though some will only be provided to professional repair companies to ensure they are installed correctly.

> New devices will also have to come with repair manuals and be made in such a way that they can be dismantled using conventional tools when they really can't be fixed anymore, to improve recycling.

> It'd be a more efficient use of money and resources to put the solar panels on a roof to generate more electricity than they'd generate on a car

This is an under-appreciated point by the solar car advocates.

In order to get anywhere close to a practical self-charging car, you have to put panels on an area equivalent to covering the entire surface of the car (including the windows!).

For a conventionally-shaped car, approximately 1/3rd to 2/3rds of those panels (depending on the orientation of the car w.r.t. the sun) are producing essentially zero electricity. Either because they are actually facing away from the sun, or just at such an extreme angle to the sun.

In other words, you get between 50% to 200% more power by taking those panels off the car and slapping them on a roof. The difference in practice will be much greater in urban environments because buildings tend to shade the street (where cars park).

No, that implies the algorithm is wrong and the chance of crime is equal. If there was an actual bias, and you searched 90% of homes based on that, you'd expect closer to 100% of the arrests to be in those homes.
For those looking for an alternative, Silhouette machines are affordable and can be driven completely offline using an open-source Inkscape plugin. (So you can cut any file type that Inkscape can convert to a path, which is pretty much anything. SVG, DXF, PDF, raster image tracing...)

Silhouette's proprietary software comes with a "store" like Cricut for buying designs, but it's a resource hog and you have to pay for an SVG cutting feature. Inkscape is a little hassle to setup but once you get it working it's great.

If they are pricing their hardware based on expectation of being able to rent seek, I wonder if someone could make a little side business buying their hardware, replacing or flashing firmware or control board, and reselling a open version of the same hardware.
>The 2-3 months you've calculated above represent 20-25% extra

That would be a one time boost and then it'd be gone forever (not a recurring revenue) . remember it would degrade wealth/asset base by 100%. Not to mention the issue that you cannot spend assets the way you can cash, you'd have to find a buyer for them (such as foreign countries or the federal reserve), but then you've basically either nationalized the whole economy or sold it off to a foreign entity.
We give month by month data in much more detail. Also thinking of building some custom models for buying a house, retirement, college education, etc. But again, this is probably not happening for a couple years - or unless we struggle to enter the small business market.
Exactly.

There is no evidence.

Anytime there is lock in on machines, there will eventually be rent seeking.

I have zero trust on this.
> In the absence of evidence, it’s entirely conceivable there isn’t enough economically recoverable uranium in the world for mass production of reactors to be cost effective.

That was actually the official outlook of the US Atomic Energy Commission back in the early 1960: They feared the advent of the nuclear age would see world uranium supplies rapidly exhausted.

This potential outlook is what triggered research into early attempts at thorium fuel cycles [0]

> The shade I occasionally see thrown toward pfSense is curious to me.

Every last bit of it is deserved. They made a promise to keep pfSense open source and they broke it as soon as they could. I see them hiding behind it's the newly announced pfSense Plus that is closed source, not pfSense CE and it's pure weaseling.

I still use pfSense but I feel bad for ever being excited about it and contributing to their popularity.
>This is equivalent to saying sky-high housing prices in Tokyo didn't need fixing, since folks could always just live in Hokkaido--a pragmatic absurdity.

It isn't even remotely the equivalent of saying that. The land mass of Japan is a fraction of the US, and the jobs are highly concentrated in their large cities. The US, as a whole, is nothing like that.

Regardless, it was a pointless argument for him to make in the first place, he was just moving goal posts by trying to equate calling employees parasites to San Francisco zoning laws. There was absolutely no point going down that path other than to distract from his original (disgusting) statement and implying that somehow people wanting more than minimum wage should really be blaming the Mayor of San Francisco for high housing prices. Which again... is completely irrelevant to the vast majority of the population of the US.
Hey, I'm the product manager for Git Systems at GitHub. Can you share more about how you'd use VFS for Git / GVFS protocol if we had it on GitHub?

Right now we don't plan on supporting it; most of our work is focused on upstreamable changes and opinionated defaults. But that could change if we're missing some important use cases.

Price fixing? You can buy music directly from artists for any price you want. I do it all the time on Bandcamp and independent stores, for both digital and vinyl releases.

Piracy set the price at 0, Spotify pulled the price up from there, but there is literally nothing stopping consumers today from paying more for music except that they don't want to.
Is there any profit to be gained from knowing which repositories are the most active? Which get downloaded the most? I mean... you'd think there would be some "market research" type of thing that could be sold, but now that I think about it more, I'm not sure. I assume most of the repositories are either OSS that are pulled a ton, or are pulled by an individual or small team. I'm not sure what the business opportunity is from that knowledge. If there was such a market for that information, I assume they'd have already tried to exploit it...
Have you ever tried it? It's not remotely performant and wouldn't make sense since GH is read heavy. Plus I'm sure they spend a lot of time thinking about this stuff, no?

If you want to get your feet wet, check out go-git[1]. It's a native golang implementation of git. They have a storage layer abstracted over a lean interface that you quickly create alternative drivers for in golang. You'll be effectively implementing poorly sharded file system on a database, then it becomes obvious why scaling the FS is just easier.
