I started the mechanical revolution in our ~30p open plan office, now a dozen or so of us use them. I'm using MX Clears, others are using Browns, there's even a red in there, the noise isn't really an issue, just don't hammer the life out if it.

Also higher quality boards with nice heavy plates lower the pitch of the sound so it's less intrusive (in my experience).
One necessity for a successful prototype is that you have a pretty clear idea of why you’re making it and what you hope to learn. You also want to consider if the cost of making the prototype will be justified by those learnings. With experience you do this instinctively, as part of the process. You know what answers you need and how to get them cheap enough.

In the case of surgery, where someone’s life is on the line, it’s not going to be worth the cost.
Just feel obligated to post two articles, from 2004 and 2006, about the imminent proliferation of air taxis. This isn't to disparage the author, Rich Karlgaard, who was (is?) simply very optimistic and enthusiastic about private air travel. But the history of the companies he discusses -- Adam Aircraft, POGO, DayJet -- demonstrates that the viability of air taxis is highly, highly questionable.

I have done over 10 years and I use chair, monitor, desk, keyboard, mouse, coffee. That's it. Printer or scanner I have never needed. The total is probably $1k or just under.

I'm assuming of course that the $1k is for the office itself not for any other tech - i.e. that the employees have a laptop.

I have the Ikea hand-cranked version of a stand up desk, and a normal Ikea office chair. Those are by far the biggest expenses but I think they were under $500 together. A good screen is $250-$600 (I got a g-sync one because this is also my gaming space and my gaming rig feeds the same monitor). Unpopular opinion: more than one big external screen is a waste.

My office supplies are a good pen and a stack of printer paper I grab from the office when I'm there. I have never seen the need for a printer or scanner or any other office supplies.

I'd say $1k isn't exactly luxurious, but if we agree that anyone can do fine with ikea furniture and one external monitor then it's just right.

It's bigger than Ronny Raygun. The first problem was JFK died before the community-based treatment centers could be funded and realized. Subsequent presidents scaled them back because they didn't understand or couldn't relate to their need. And so, Cook County (encompassing Chicago) jail run one of the largest mental healthcare systems because state, local and federal government has failed to do so.

You're right that it's different, but this is nothing like the dot com bust. People could still do other work when that happened. Also note that equity busts are quite different from credit busts.

This really is a massive bomb under the economy. Credit is stretched by years of low rates and now a lot of things have to stop.

Other commentators hint at postponed spending, which would be good. But many things in the economy do not work that way. If you skip your holiday now, it's not coming back and the hotels and restaurants will not get that money later. Same with a number of other businesses.
Curious to what you think that would achieve market wise. Hackable does not seem to matter much. Everything in the sub $100 dollar range I've tried is crappy (battery life, as well as functionality wise) because that's all that particular market segment is willing to pay for, those that want access to one of the viable app ecosystems seem to be prepared to pay the usual markup. Don't get me wrong, I love tinkering with the hardware form factor myself but that doesn't mean I'll create apps, no less an app ecosystem, that make this more viable to the manufacturing side of things. Maybe low cost devices with access to the Android ecosystem become more viable in the future but other than that changing this niche seems relatively hard and producing hackable devices historically goes counter to the approach of any company I can think of in the space. I could see somebody like Arduino creating something appealing and approachable for the rest of us but that would be unlikely to make a dent market wise.
Amusingly, the Casio G-Shock has been made more expensive. That thing solved timekeeping. Rugged, solar-charged, corrected from radio time signals, and under $100. At last, the zero-maintenance accurate watch.

But not expensive enough, so they now have models up to $500.
I appreciate they have a whole section on disadvantages, but this stands out to me: "All-remote companies should consider meetings as a last resort, instead relying on asynchronous collaboration tools[...]"

To me, this implies a further disadvantage: extremely high latency when compared with in-person collaboration. That can be fine for some things. But there's all sorts of work where I really value live discussion.

I know that some remote-first companies tend to group related work by timezone, so that teams can be both distributed and low latency. I take it Gitlab isn't one of those?
> I'm guessing it's the pretense that you can simply teach anyone to meditate whether or not they want to learn

Meditation techniques aren't hard to learn, they're comparable to any form of exercise. The hard bit is in doing them sincerely, just like any form of exercise.

Can you teach someone press-ups? Then you can teach them meditation. You just can't make them do it, or effectively.

As to signing up for solitary for an extended period, I wish I could, but only if it was humane (e.g. no violence, feces flung at me etc), which I'm willing to bet (and the article seems to back up my suspicion) prison solitary isn't.

Just to clarify again, this is at the Amazon Go Grocery store of which there is only one location in Seattle.

I don't use the Amazon Go app. I use the Go option within the regular Amazon app. I get no email and no status change within the app for over 1 hour.

Also, I'm really not that convinced that they have mastered picking up various fruit and vegetables and the bakery items I chose. Those things don't use RFID and from what I could tell their system must be vision-based online here.

Edit: My friend was with me and used the Amazon Go app and also didn't receive any message or receipt until an hour later. This has been a frequent occurrence at this store.

I find it interesting how they achieve this and it also gives people in remote places the ability to work for such a company.

You don't need it, but sets are more primitive than numbers.

For example, the category of finite sets without an NNO [1] is simpler or more foundational than the set of natural numbers. At the same time, this category is actually a category of numbers.

My point is that numbers are complicated by nature, but they are more intuitive for humans (mostly I think) than sets are. Sets are simpler or more basic, but often less intuitive for humans.

Amazon Germany. Before the panic started, I was looking to buy sanitizers for the office. 4x500ml was €120 at Amazon from third party seller, with delivery time 2 to 3 weeks. The same seller, directly on their website, ... €50, delivered 3 days later. Amazing.
From experience, maybe one hour away from the Austrian border, easures are nowhere near what Austria or Denmark are doing. There is a 14 day self-quarantine rule in place for public institutions like schools and so. When you have been to what is determined to be a high risk zone, you have to self quarantine for 14 days, starting with your last day in that zone (happened to us, we have four days left till Sunday). Most big companies I know of have the same rules in place.

Events over 1,000 people are cancelled, how that applies to larger schools is currently being discussed (source: my sons school is over 1,000 students).

Communication is a little bit of an issue so, we found out about the high risk zone declaration by chance, more or less. On the other hand, case numbers are really low, so I think it's kind of trade-of thing. In denmark the increase in cases triggered the response.

In France on the hand, everybody with any symptoms resembling Corona are sent on sick leave for at least a week, over the phone. People not needed in the office work from home.
It's also possible that (too many) people treat this thing as a temporary distraction, throw their hands up in the air, and don't even try to be seriously productive; blame the conditions for no work getting done. Kinda like "github is down and I'm compiling and there's a group of visitors in the office..."

So it might kinda backfire on that front.
> It's a bit unfair to compare the speed of wildly inequivalent things.

Yes, but I understand you keep doing it because you don't understand this stuff very well yet.

> RocksDB would be more comparable

How do you figure that? RocksDB is not a programming language.

If you combine it with a programming language like C++, it can, with only 4x the hardware just about keep up 1/6th of my macbook air[1].

RocksDB might be more comparable to gdbm, but it's not even remotely like q or k.

[1]: And that's taking facebook's benchmarks at their word here, ignoring how utterly synthetic these benchmarks read: https://github.com/facebook/rocksdb/wiki/Performance-Benchma...

> much stronger resilience guarantees,

You're mistaken. There is no resilience guarantee offered by rocksdb. In q I can backup the checkpoints and the logs independently. It is trivial to get whatever level of resilience I want out of q just by copying regular files around. RocksDB requires more programming.

> gives you access to all your data at once

You're mistaken. This is no problem in q. All of the data is mmap'd as soon as I access it (if it isn't mmap'd already).

> Calling them expensive is ironic AF. Most of them are free and open source.

If they require 4x the servers, they're at least 4x as expensive. If it takes 20 days to implement instead of 5 minutes, then it's over 5000x as expensive.

No, calling that "free" is what's ironic, and believing it is moronic.
if we apply the same thinking to other industries, the prices of goods would skyrocket.
I WFH all the time. I was able to design the product that our company now sells, write the initial code, hire the team that built it and sometimes manage some of them, all remotely. I dunno, the things I read about WFH imply that shouldn't have been possible but it was.

I find almost all meetings to be a waste of time. Maybe 1:1s are the exception, but they're also pretty much optional - good to have a catch up with team members sometimes but if someone can't make it that day no big deal.

The problem with meetings is that a well run meeting needs to have an agenda and ideally written minutes, I don't think anyone disputes that (except for casual 1:1 catch-ups which don't). So you end up writing anyway, or wish someone had. Without the writing aspect meetings are often poorly disciplined, achieve little, run over and end with an agreement to organise another meeting.

In the end, work - the production of useful artifacts customers will buy - gets done alone. It doesn't get done in meetings with colleagues.
I do have a work laptop but I never use it because I hate working on the small thing(I don't like laptops that much in general). But when I work from home I use my home computer as it's really powerful(much more so than my work desktop also) and i have dual 25" monitors.
It's certainly a nice solution, but OP's solution has the nice property of working directly on a universality definition, which makes the argument more general. For example, the universality argument also works for the infimum and gcd operations.

People have been using this for years. One of things I recommend is not using the repository pattern. You end up with a repo with lots of methods on and overly generic.

For each of the use cases/interactors, any database action should be wrapped up in a specific interface for that database action. Then implement those database interaction by implementing that interface. Query and command objects instead of repos.

Much finer grained then repos. Also allows for finer grained control over which data source you use for each interaction.

How to properly handle the Covid situation, by Denmark government
This is a very neat project, I really wish I could read Russian to understand some of the details in his writeup. The overall architecture is pretty standard for a LIDAR setup.

For the source they are using an osram SPL PL90_3 laser diode which provides 75W peak output at 900nm, with pulse duration roughly 10ns and costs $10.

For the detector they are using a MTAPD-07-013 avalanche photodiode, which has a quantum efficiency of about 80% and an internal avalanche gain of 100 and 0.6ns rise time. Also costs about $10.

For the time measurement they are using a TDC-GP21 time to digital converter with 22ps resolution, although the author has it configured for 90ps counts. Costs a bit over $5.

It is really a testament to the amount of development work that has gone into the lidar and related field, that for under $100 you can build a full lidar system out of parts from digikey including custom pcb's and scan mirror. When I was in grad school we paid $7500 for our avalanche photodiode, $25k for our pulsed laser, and used a $50k oscilloscope to read it out.
Communiction and information realls sucks, that's true. Same goes for a coordinated approach between states. Other then that the situation is more or less under control, as far numbers tell us.

Regarding school closings and such things, at last Bavaria is prepared for that (my sons school is over 1,000 students and might be clsed in the next one or two weeks regardless of cases due to that number of people there, but that is just a snapshot, so).
For what it's worth, there's still a <$100 model with all those features.

It's worth noting that not everywhere has a time signal to sync from. Notably, Australia. In those places, if you want a watch that doesn't need manually setting you either need to get one that syncs with your phone, or one that can receive GPS signals. Both exist.

Then you should also have monks as supervisors in those solitary confinement cells.

You can't make actual change to an individual. You can give them an opportunity of course, but not change them. Some will harden their person and some will just break, you want neither.

Show them humanity, love and give those treatment that need it. Focus on the positive parts and lift those up. Solitary confinement can only be of good if it's chosen, much like any personality change.

Admit that it's not the prison that is a problem, it's that youth problems is not properly dealth with. (as pointed out in the article)

I don't see any focus on this in neither local or global politics. It's odd that it's still given today that we could possibly bully each other to a better behavior.

Perhaps they should. Our current economy of cheap, disposable goods is only possible because of the (relative) exploitation of the poor.
>At last, the zero-maintenance accurate watch.

I imagined this to be the case when purchasing my $500 solar G-Shock, but it needed the battery replaced every 3-5 years, and the work had to be done by an authorized Casio repair center; local watch repair people refused it.
In the US the most notable problem is the tests. They had this grand plan to gets millions of them produced and be available at every local testing clinic, which ran into one misstep after another.

Do you recall the international coverage of Hurricane Katrina? It was dominated by the stories about rape gangs and anarchy which all ultimately turned out to be false rumors. Media everywhere sucks like that to some degree. As an american, I probably notice the bias towards stories that make the US look bad a lot more than you might.

Though I get what you're saying. US media may be one of the worst in the developed world. I don't even look at it anymore. Lucky I learned about coronavirus from here and adjusted my plans for it. And the NYT in particular seems to be really anti-China since they got blocked in China a long time ago.

Quoting from a blog post I wrote [1] which included a note on this documentary and why I think it made an overly positive case for Vipassana and its effects on prisoners in Tihar Jail:

> There is a popular documentary on YouTube called “Doing Time, Doing Vipassana” on the introduction of Vipassana into Tihar Jail (probably the most populated prison in the world with a current population of 17130 prisoners), and how Vipassana improved several measures of psychological well-being among the inmates that undertook it — things like anxiety, depression, sense of alienation from mainstream society, etc. This has become such a success story for Goenka Vipassana that Kiran Bedi — Inspector General of Delhi Prisons at the time — is invited to speak at major public events organised by the Goenka Vipassana organisation. Having become a Vipassana enthusiast herself, she praises it freely in TV interviews and even the odd TED talk.

> But to me this is yet another example of bad science in which meditation seems to get a free pass. Introducing Vipassana was not the only improvement Bedi made to Tihar; she arranged vocational training for prisoners, introduced Yoga classes, organised sports events and celebrations for religious festivals, established petition boxes and went on daily inspections, interacting with prisoners and listening to their problems. Just like patients who feel better after homeopathic treatment, what may have mattered more to prisoners was that Bedi was actually trying to help them; they knew this and therefore already expected things to improve in their lives. Also, there seems to have been no control group in the Vipassana Tihar research. Prisoners who volunteered to learn Vipassana were segregated from the rest and may have been treated better overall. There should have been a control group that was also segregated and in all respects treated the same as the Vipassana group except for the Vipassana part.
