This is what I do. I have a small dynamo table and a Python script I run from cron. I grab all updates since the last run and apply all changes to the running service. I have the config option set to write out the config on service stop, so I don't lose anything on a restart and don't have to replay everything. I have lots of room for improvement but it's a quick hack that works for my needs. (Not sharing yet because it doesn't fully CRUD right now.)

Medtronic Publishes Design Specs for Ventilator to Combat Coronavirus
The older military and aviation boards we make still all use lead. Changing to lead-free requires an extensive re-certification process for each board, and no one at any level wants to do that. Which seems to create a belief that lead is manageable and okay. Interestingly, the board assembly shop still prefers lead because the boards are apparently easier to make.

Rosin-core is popular because it's a 1-step process. No need to put on the liquid, which seems to make at least the same mess.

> Finding a suitable respirator is not just a matter of choosing a model you like or by the cost of it. You may need to try different makes or sizes to find one that fits without leaking around the seal and letting dust in. A respirator that depends on face fit is ineffectual if you have a beard or thick beard stubble. The only way you can know if the seal is good enough is by having a proper respirator fit test. At present this is also the only way of meeting legal requirements.

When I was in high school rosin core was used and the teacher talked about it like it was some great forgiving stuff that even if you didn’t use enough flux the core would help you but I agreed messy. I am however used to working on a poor mans budget and only do home electronics, last thing I did was solder and hack a Xbox 360 and rosin core is the only solder around here you can find so I make do. Also can’t buy flux without ordering online so I ended up collecting pine sap and soaking it in alcohol then filtering and evaporate the alcohol to make my own flux. It actually works just as well as any commercial flux I have used.

Ask HN: What service should have an API, but doesn't?
I often have ideas for fun projects that hit a brick wall when I discover that a popular service I _assumed_ had an API in fact does not.

Examples: Netflix, Kindle, ClassPass, OpenTable.

Often these services do have _some_ kind of API—but it's super limited and/or only available to huge enterprises.

I'm curious if other people on HN run into this problem—and if so, what's the #1 service you wish had a powerful, startup-friendly API?

I've been hearing about modern JavaScript development revolutionizing "everything" for the past 8 years. So, can someone name me any significant impact it made on figuring out what to do about the recent epidemic? If not, I think it's worth reflecting on what value we get out of the technology that sucked up so much of our intellectual, financial and computational resources.
Interesting... I'll have to take a look at what the utilities are actually done then and how they're loading the keys into the interface

Look at the length and substance of that comment of mine and the one that started this subthread. They are similar in length, similar in glibness. I don't know what the score of gop is but it's not grayed out so I'll assume it's higher than the score for mine. What is the difference in the two? Maybe homophobia is more palatable than nazism. Maybe mine accused the reader instead the author (but almost everyone that responded defended card). Maybe Wikipedia is more authoritative than a literary journal.

Here's the official data: https://onemocneni-aktualne.mzcr.cz/covid-19

It shows various trends, numbers of tests, numbers of new positive people, etc.

Looks like the latest datapoints (fewer new cases) coincides with less testing. But it's hard to interpret. It may be the weekend (very nice weather), or it may be that less people are asking to get tested because there are fewer serious cases.

We'll see soon how it develops further.
In other words, you don't like either of existing solutions, don't know any better solutions and you're pissed off that people can't come up with better solutions.

The React Router Repeats Itself, First as Tragedy, Second as Farce
I feel like this is a valid concern, but really when it comes to abusive relationships ... a lockdown isn't the problem / aggravating circumstance /etc.

I worked with kids who came from abusive / were in abusive families. The volume of abused partners who willingly stayed with the abuser was astonishingly high. They would even follow an abuser from one town to the next, even with services and options to not do so available.

That's not to blame them, and circumstances make things very hard (especially if you're poor, have kids, or both). But it is the simple reality that the abused partner's willingness to leave and stick to that decision was the real trigger for any positive change, and not the circumstances of their life. It is not an easy decision or easy thing to do, but there was just not getting around that it was the key too.

Obviously you can't just throw that at someone being abused because recrimination is of zero help / won't make things better.

Either way in a lockdown, or out of one, the victims are often just as "locked" in psychologically.

One aspect of this that the GP noted but has not been addressed, is the following. If you are an executive of the company you very likely have stock options which allow you to buy stock at a preferred (already set) price. Then you support a stock buyback, which inflates the price of the stock, making your options even more attractive. When you exercise the options, you purchase stock directly from the company and the difference essentially comes from the existing stockholders.

I wouldn't necessarily refer to this as "stealing" but it is a sneaky way to increase your compensation as an executive. It also causes a conflict of interest when a company is deciding whether to issue dividends or do a stock buyback.

Thanks for your comment dhosek! Indeed most of the coworking spaces are closed but in certain regions of the world (like Sweden or even Germany) the government did not instruct them to close so some of them still operate with a change in their policy (for instance shorter working hours, reinforcing their cleaning policy, handing over hand sanitizer to members, etc...)

one major use is that it opens up the TLD space which is currently bottlenecked by ICANN

Another use is the ability to actually own your own domain name (instead of rent it).
We might also take some delicate thoughts that the absence of a lockdown does not imply the absence of captivity. An abuser can leave for a workday, or weeks at a time, and still have a captive.

But I very much understand the spirit here and now I am feeling sad thinking about all those people out there that are possibly suffering even more right now. I can hope that some of them find the strength to walk away after experiencing this, but I know fully well that this isn't how it works.

It's crappy how I feel like I can change the world if I try, but I can't change the house down the street.

And for all those other houses down the street that look happy, they could be hiding the biggest captives of all.

What a heavy topic to unwind.

> so if the state space is big or infinite, so will be the resulting generated JS.

I understand that, but it's not like this doesn't already choke on big input spaces. Why not allow me to use a big input space with a small state space by exploring the state space instead? Otherwise you just seem to be exploiting the fact that small input spaces make for small state spaces, which seems like an unnecessary indirection.

Or is it to try to enforce small state spaces to prevent programmer error?

Preparing for a Recruiting Event
Ask HN: Soliciting Donations for Maker Nexus Making PPE's for Covid19
I don't do solicitation, but this is a good enough cause that now I am. I've become the person I never thought I'd be. I am personally volunteering with a non-profit that is making a critical health care item and giving them away to hospitals.

I'm writing in the hope you would pass this on, hoping it finds some corporate philanthropist who would be interested in funding this excellent cause I volunteer for making face shields needed by health care workers. I thought you might have a network that reaches far.

You probably know that there is a critical shortage of personal protective equipment (PPE) for health care workers in this crisis. I know of one nurse who works at a major hospital in San Jose say, "we're making face shields from shower curtains and hot glue". I asked a doctor friend who works at a free clinic in SF if they are running out of face shields and he said, "are you kidding? We have never had any."

You probably don't know that the non-profit I volunteer for (Maker Nexus) is busy making them and giving them away! We've turned our whole makerspace into a face shield factory. It's a war and we are in the thick of it.

Oh, my apologies! I got the impression that the process of making them has the end-result of lots of closed off bubbles. But you're right, reading the wiki page again shows otherwise:

I loathe safari. I use Brave and only switch to FF when something doesn’t work in brave.
[Continuing from the Ask HN text...]

Our place is 3D printing headbands and using our industrial laser cutter to make the shields. Add some elastic and a video on how to assemble these and off they go to places like Valley Medical Center. We're sending 500 to them on Friday and 1000 to a local Kaiser hospital next Wednesday. We have way more requests to fill. Local hospitals need this stuff.

We can make about 85 a day in house, but a lot of people in the bay area have their own 3D printers and we have invited them to make the parts at home and drop them off at Maker Nexus for packaging with other parts and shipment. We have plans to be at 1,000 faceshields a day in the very near future. That could really make a difference in keeping health care workers safe so that they are there when we need them.

Imagine a time where the hospitals have only half their staff because of sickness! Not only will new corona virus patients have no one to take care of them, but there also won't be staff to handle broken legs, heart attacks, car accident victims. This could affect us all.

And we're working US wide. We had a contact in Pennsylvania that was making the 3D printed parts of the face shields but did not have a way to do the laser cut part. We shipped him 300 of the parts he needed.

And we're helping the world. The original design of the face shield was made by a company called Prusa in The Czech Republic. We worked with local hospitals and evolved the design significantly to make it more effective. We have shared our work back with Prusa so they can update the plans they share with the world.

These face shields cost us about $5 each in materials. Not even counting our rent of $18,000 a month. And utilities. And maintenance on the equipment. And other stuff. For us to ramp up to 1,000 a day means we have to raise $5,000 a day. We're getting a lot of $100, $200, and even an occasional $1,000 in donations. This is fantastic, but won't get us to 1,000 face shields a day.

$5,000 a day is a huge amount of money for a small non-profit like Maker Nexus, but to give protection to 1,000 health care workers is a tremendous impact. And we can do that every day if we have the money. We are not going to have to do this forever, but right now we can make a huge difference. We need this money now if we are going to get these hospitals and clinics the protection they need. A single donation of $50,000 would let us make 10,000 face shields.

FYI, I'm sending this plea on to other friends as well. But if you know of some philanthropist that would be willing to make an impact, I'd love a chance to tell them about us. Please send this email on to anyone at all.

I'm including some links below that will give you more info - one of them is a video we just did today for the hospitals.

Using computer vision, it looks at the flow rate and arc of the weld and turns any mediocre welder into a good welder.

Having been in a power plant factory in China (which is to say a factory that makes power plants) - bad welds are still very much a problem and a system like this could go miles to improve the craftsmanship of medium skill work there. In the US or Germany a headset like this may cost a few grand (going by Dräger Xplore 8000 prices) but even if China finds a way to get them down to $200 (as with the Shanzhai AR headsets) it's still nearly a months salary for a worker - questionable if an operation would spring for it if they're cutting costs so many other places.

I find melamine foam, like Mr Clean magic erasers, makes removing assorted drawing implements from walls a lot easier. It'll even remove pen and pencil. I add a little soap and just scrub away, rinsing frequently.

You have to be careful because it's an abrasive and some wall surfaces might not like it. It seems fine on the paints I've cleaned, though.
