A great explanation of a lot of things, but this looks wrong to me: "To put a number on it: surgical masks on the sick person reduce cold & flu viruses in aerosols by 70%. Reducing transmissions by 70% would be as large an impact as a lockdown!"

Reducing the amount of virus in aerosols won't reduce the number of infections by the same amount. If a cough produces ten times the infective dose, then with the mask that's still three times.

Masks are still likely to help (and maybe having a smaller dose will make the disease milder if someone does catch the virus), but it's not possible to make a statement like this about the effect on R.
I've really liked the BBC content that I've managed to listen to. But their catalog really show the navigation, discovery mismatch between established publishers and the podcast networks.

Podcast UIs need trees or facets or something, to ease drill down.

Much as I've disliked the NextStep (iTunes) panel navigator, I really miss it on mobile.
I don't have to agree with someone (on every point) to find a conversation with that person intellectually stimulating.
The discover part takes place on Bandcamp, but Bandcamp's involvement ends after you've bought and downloaded the music. The enjoyment part that comes afterwards happens on your device, using whatever music player you prefer to play the files you just downloaded. It's enjoyable because you get a bunch of zipped, DRM-free .flac files you can play on any device, instead of being bound to some specific app or in-browser player.

At least that's what I think the intended use case for Bandcamp is. That's how I've always used it.
oh we can most definitely manufacture a phone, but since we don’t have slave labor and questionable human rights it costs us more to do so.
AFAIK there's nothing mutually exclusive about using a service that requires identity (in this case, proof of unique human-ness) on a decentralized blockchain. In fact there are services that are actively working to create DIDs (like brightID, 3box, etc).
I was a Java developer for more than 4 years at the beginning of my career. I was more of application developer than language expert so I did not know about nooks and crannies of the language. But that is exactly what was being asked in interviews and was never able to crack those interviews.

I liked Go and used to work on it in my personal time. Go's way of doing things is usually one way so there are not many things you have to remember about language. I applied for a job of Go and I landed that one. Of course, at that time very few Go developers were there in market so that could be a good reason for me landing that job as well.
I genuinely think PEDMAS/BODMAS nonsense creates permanent barriers to understanding in math in some people because it inculcates an understanding of the symbols like + and - as being sequential operations, and they struggle to ever make the leap from math as ‘calculation’ to math as ‘reasoning’ as a result.

Do you do code reviews on committing to develop? Other companies/organizations generally have develop for work in between releases and merge into develop from feature/bug fix branches (primarily owned by one individual) with pull requests. The PR provides an opportunity for team code review and feedback before merging into the shared develop branch. That also allows developers to commit and push unfinished work to their own branches, so that it is backed up on their remote repository rather than just their own laptop. Otherwise if they pushed straight to develop, they'd constantly be breaking that shared branch with non-functional, partially complete code.
At least in California, restaurant and bar licenses are separate. Restaurants have to prove that a certain percentage of their sales are food related; otherwise you can’t allow anyone under 21 into the establishment.

IME the improvement to readability is worth the cost of a few extra assignments.
I actually wouldn't be surprised, if this were a reverse-proxied piece of software.
Perhaps - my own pet theory is it was just some bored guys on 4chan who did it because they could.

The thing is, a lot of the bots didn't submit comments directly, which would have required getting keys to submit in bulk and leave a trail. Instead, they filled out forms on the many sites that were set up to take names and submit form letters to the FCC. So some advocacy org might set up a site and get a million comments, half of them might be legit and half might be from a script kiddy running a database of addresses and names through the site, which then submits it to the FCC. The site has no particular incentive to vet the submissions. Knowing the IP address of the entity who sent the message to the FCC is close to useless, in that scenario.
Been hearing the same hype about Roam Research, just as Slack, Zoom, and countless other 'shiny new' consumer tech products.
> Having to use journalctl instead of reading a plaintext file in /var/log should have resulted in a swift slap upside the noggin the moment it was first considered.

I absolutely love the idea of journalctl (without commenting on the execution).

As an admin, there was always the chance that $DAEMON_OF_THE_DAY put their logfile in a particularly creative place, thus sending me on some wild goose hunt. Now it's just `journalctl -u $DAEMON` and that works immediately, every single time.

Also, as a user running journald on a notebook, I love that it's just one config switch to send all the logs from all the services to /run instead of /var, to reduce the write load on the SSD. Sure you could fiddle with a bind-mount but that would have to happen very early in the boot process so I don't think it would be as reliable.

As a daemon writer, it's one less option for me to care about. Especially when my daemon is just some bash script, logging to stdout is the easiest way.

And logging to stdout also meshes well with running the same daemon/script in container environments like Docker or Kubernetes where containers usually don't even have syslogd. (In fact, I have containerized a service that requires syslogd and that was kind of a pain. I ended up using a mini-syslogd implementation that just dumps all logs on stdout so Docker can pick it up.)
Little did I know: there is a "Combustion and Flame journal".

Exciting.

Seems like that could be mostly automated
One thing I forgot to add: In pockets of the ethereum community, it is widely considered that having identity mechanisms that can be relied upon is one of the things that is holding blockchain services back from going mainstream. There are all kinds of applications (decentralized social networks, payroll, voting, etc) that could benefit from having an identity overlay on a blockchain network.
0) I kind of wonder how anything that reads as a typical piece from a certain culture could not be criticized for massively ignoring the rest of the world.

1) In France most restaurants sell the same desserts that they buy from the same wholesale Metro that's open only to food professionals. They buy it less than a euro and sell it more than five, with a bit of an english cream they buy by liters.

2) Not sure what's your source, but I suppose running a tobacco shop would be far easier. I have yet to know one restaurant owner who has 0 experience as either a waiter or a cook.

3) Basically you're saying that doing 0 business activity is "not too bad", when you still have to pay the rent. Just because you've spoke with a couple of owners in Italy and Japan.

4) You can be good, but paying for a 10k/month rent + furlough and making absolutely 0 business activity after throwing away your stocks can kill your business even if you're a "good restaurateur".

But maybe Simone is right: if COVID killed your business then it's because you're not "good enough".

I've yet to read such a both senseless and self sufficient comment on hn.

Nice culture, nice inclusiveness, maybe one day you grow a heart.

Not sure why google/Apple would know any more than they know your bank details.

Your hospital would now when you ask them for a year, same as they know when they process it.
Quite a lot of books I want to recommend are already here.
- Hard things about hard things
- Good Strategy / Bad Strategy are a couple of books that can help here

If the purpose of this exercise is to improve your overall understanding, I would recommend something more fundamental than above (software-specific business books). Read some Macro Economics, articles around industries you are interested in (SaaS, Mobile, etc.) - especially historic ones which give you more foundational understanding.

Also, I strongly recommend not doing an MBA program if knowledge is what you seek.
Curious if you believe that because it's not working today it means we shouldn't talk about it as a path forward?
Automation seems like the answer. Surprised it hasn't come to that already.

Hand-labor today is used as an interim solution, when the scale doesn't justify bespoke automated assembly line. When factories are 'brought back' to the West, its because they scaled up and automation is now affordable.
I did read about how Swedish hospitals stopped using chloroquine for COVID-19 due to severe side effects. I've googled, but I'm unable to find anything definitive regarding whether or not Sweden has given up on hydroxychloroquine, which seems to have less severe side effects. In the US, hydroxychloroquine can only be obtained when prescribed by a doctor (depending on which US State you live in, your governor may or may not allow it to be dispensed outside of a hospital setting). Even though hydroxychloroquine has been around for over 70 years, there's risk associated with it. It's obvious to me that the front-line doctors at Yale are throwing everything they can think of at this virus to keep as many people out of the ICU as possible. They've obviously made a lot of progress in a very short time. It reminds me of the way some startups with minimal runway develop an MVP and then keep iterating in an attempt to get better results. It's a harsh environment, but that's what forces people to innovate quickly, and sometimes succeed. As they say in the movies: GO! FIGHT! WIN!

Similar concept with different data that we are deploying in US hospitals. Using React and Hasura.
I thinks this article packs several engineering lessons and that this part is one of them:

It's great they went that route and did their best to stick to what doctors know by heart, instead of going creative.

Sigh. I've had to deal with this as well now that our engineering org is full remote. What it comes down to is that our leadership doesn't trust us, even though we consistently and repeatedly deliver releases on time and on budget. If our engineering leadership was comfortable with compensating us for the desired outcomes they want to generate value for the company, this wouldn't be an issue. Somehow I'm guessing they feel uncomfortable that we could all be getting our work done in 4 hours every day and then going outside to play.

Cargo culting is the practice of blindly copying a solution without understanding why it makes sense and when it might not apply. You're describing the opposite.
I'm not sure what point you're trying to make. But if it's that the identity mechanism on Gitcoin (aged github accounts) isnt perfect, then I think you're absolutely right.

I think a more important question is "are the round results valid?" Vitalik goes into this in his post - As Vitalik notes in his post, we are certainly reaching the limits of our existing identity framework as more money/users get involved.

Identity networks are a chicken and egg problem. My view is that Gitcoin being one of the first widely/actively used Ethereum products (https://gitcoin.co/results) we have a unique opportunity (and challenge/responsibility honestly) to bootstrap a DID network.

Here's some incremental improvements were gonna make in round 6:
Identity - https://github.com/gitcoinco/web/issues/6549
Collusion - https://github.com/gitcoinco/web/issues/6548
All maths functions where it makes sense take arbitrarily many arguments. (+ 1 2 3) = 6. (< 1 2 3) = true. Everything in function position (directly after an opening paren) is either a function you want to apply or a macro you want to expand, except in a select few forms, such as binding forms and conditionals. The syntax of scheme is remarkably simple once you know the basics.

I have programmed python for about 20 years, and I still do stupid mistakes. I grooked all the r6rs scheme syntax in 20 minutes, except for (do ...) which somehow never sticks. It is also rarely used.

I have tried to evangelize scheme enough to know some people just don't like it, but for me it instantly clicked.
It’s very common to rent a dishwasher. High volume dishwashers break down all the time and need very regular servicing and cleaning. At every establishment I have been associated with (wine industry) I’ve been on a first name basis with my dishwasher service rep.

With linen, when you go through a big volume, it is infinitely easier to use a linen company than to do it yourself on site. You’d have to buy industrial washers, pay rent on space to keep them, know how to service them, pay staff to operate them, etc...

If you’re a large chain, perhaps you could bring those operations in house. If you’re tiny, you could do it yourself. But if you’re seeing over 100 guests a day, there’s no reason not to use service companies for these two examples.
Strange lights in the nighttime sky happens to be the SpaceX satellite ‘train’
The question I have after reading this press release is, "Why was it previously thought to be impossible?" as stated in the beginning of the article.

Further down, the release seems to indicate lots of people thought it was possible and have been studying it, "The technology has been studied since the 1960s but had not been successful due to the chemical propellants used or the ways they were mixed."

So just an engineering problem, which are seldom impossible.
Google in their interviews for product owners are testing for such skills:
- creativity (ability to looks from different angle)
- estimation (possibility to estimate something with minimal information, e.g. "how many gas stations there are in Germany?")
- communication (ability clearly articulate what's in your brain and set bigger tasks in smaller pieces)
- knowledge on subject (technical skills in Google's case, they have one coding session with product owners during their interview)
Yeah, I wasn’t expecting much, but it sounds like a real potential breakthrough.

I’d love to see someone with experience in the industry comment

This is really great news and I admire the judge's dedication to truth and justice. It makes me wonder how much pressure the judge recieved behind-the-scenes before making this ruling. Excited to see how this develops. Unfortunately I suspect the answer is probably more mundane than anything; e.g. the comments were from a botnet which the FCC lacks technical competence to deal with.
As with my examples above (linen and dishwashing) ice machines are also notoriously difficult/expensive. They most certainly have to be cleaned & serviced regularly. When the Board of Health comes in, the ice machine is one the first places they look as it’s basically a invitation to a mold party without diligent cleaning.

I remember that there were websites that allowed users to comment on NN that had pre-made comments already completed. The user only needed to enter a valid email address and could then forward the comment to the FCC or erase and put in their comment in their own words.

They're not uncomfortable about it, they see that as breach of contract and would like you to either take a pay cut or work the full 8. We get paid 'by the hour' and not by a contracted amount of work no matter how much time is spent. Our whole regular workforce is structured around hourly wages, full time and/or part time employment in something described as a 'job'. If you start upending that it is important to realize that employers have a dominant position right now and that upsetting that position may not end well for those that really only do four hours of actual work during an 8 hour day.

Excellent blog post. One of the big issues, unfortunately, is that there are too many of THEM. I just sat through a job interview where they bombarded me with topics and asked me to rate myself on a scale from 1-know nothing, 2-familiar and 3-expert.

I immediately understood that this was a pointless exercise for me. I knew That I don't consider myself an expert. I haven't studied any topic long enough to call myself an expert. On the other hand, I like to believe that I don't fall in the "clueless" part either. I have worked in the computer industry form many years now and have overall pretty good problem-solving skills and am able to produce work that generates value for my employers.

Still, I learn every day and improve on my skill, but it will require a lot before I dare to call myself an expert. Others call me an expert, a wizard, and other nice things, but this is never anything I would use to describe myself.

I never got the job offer. Good riddance! I doubt I would have accepted the job anyway.
IANA Rocket Scientist, but I'll try.

Rather than have one big continuous burn, the rocket engine rotates to create many small burns, by mixing and igniting small amounts of two gases at just the right frequency and amounts. This apparently leads to a more efficient conversion of chemical to kinetic energy.

This sounds similar to how a car engine uses a fuel injector to inject then burn small amounts of fuel to make the pistons go.
