Here in Ontario, Canada we have an online food delivery service (https://grocerygateway.com) and they built a super-automated distribution factory to help run this (and all of their stores in the area).

A distribution center in the UK has already mastered this:

> The Ocado Andover CFC is a three-storey grid of storage crates containing groceries. On top of the grid a fleet of 1,100 robots grab items and deliver them to “pick stations” where “personal shoppers” assemble orders for delivery. According to Ocado, an order of 50 items takes five minutes to pick and pack.

Google "automated grocery distribution", there's plenty of examples.

This is essentially unskilled labour moving boxes from one point to another. The exception is vegetables/fruit where a human discards the bad stuff before it goes into another box for delivery on a truck. 95% of that process could be automated. Including eventually the delivery drivers in between the distribution center <-> retail endpoint pickup centers (where consumers and last-mile Instacart/delivery drivers can go in person for pickup - I'm assuming humans will be needed for home delivery for a long time).

Instacarts biggest drawback is the cost and how they nickel-and-dime you, but GroceryGateway is run by the grocery store itself, and it's much better and actually helps you save money by shows you all the deals in the interface (imagine sorting a grocery store by discounts and price, as you walk through it gets more expensive). There is very little markup vs the stores, I've found it to be cheaper in practice, especially factoring in my time.

A fully integrated/automated version of this with far less urban real estate + labour costs will bring the prices down significantly.

I have a feeling only smaller luxury/farmers market/vegetable+fruit+meat only (+ semi-automated pantry section) shops will exist in the future. You don't really need to pick up most stuff by hand, but an in-person browsing UX can still be useful. Ikea stores are halfway to figuring this out.

I try to write C/C++ so that the state and flow of control is fairly obvious in a debugger. Complicated and "electric" statements like the ones above are succinct and maybe even obvious, but they're difficult to step through, and they don't really offer any advantage in code quality.

Yes exactly (I've lived in Germany). And where I live now in southern California, thank goodness, it's actually against the law to "solicit door to door" (I think that's how the law is written).

Be careful not to conflate CFR with IFR. CFR is the number of deaths divided by the number of confirmed cases. IFR is deaths divided by total infections. It's hard to determine IFR, but CFR is almost always an exaggeration of the risk.

> It's unreasonable to expect a developer to accommodate for the failure of any SDK call.

This is not even remotely close to unreasonable. In fact, it is the opposite. Doordash, Uber, Lyft etc. are completely dead on arrival due to a remote bug that could have easily been protected against.

During SDK initialization, if shit hits the fan, pull the chute and inform the user that things cannot proceed. Easy as pie. If you do not have that level of control or the foresight/wisdom to implement, well yep you are going to be the victim of a situation like this.

Besides that, it wouldn't work on at least linux. You'd get the error:

because of how everything after the first space is taken as one argument in the shebang.

> Surround your variables with {}. Otherwise bash will try to access the $ENVIRONMENT_app variable in /srv/$ENVIRONMENT_app, whereas you probably intended /srv/${ENVIRONMENT}_app.

I think using the braces all the time instead of only as needed is an exaggerated solution. The rule of what's parsed as the identifier is pretty intuitive. `_` is a valid identifier character so the identifier continues. I can't see this mistake not being obvious, especially with syntax highlighting. I think adding braces all the time would just add too much syntax-cruft that would obscure important details.

They did say though that flying to China was still okay in as late as February. For what? Fear of CCP?

If this virus had come in some African country, they would have no problem in closing everything out - as anyone that understands tail risks would. But because it's China, then the recommendations for actions come after the evidence can not be hidden anymore. It is immoral.

The WHO sent out a Tweet back on January 14 saying:

“Preliminary investigations conducted by the Chinese authorities have found no clear evidence of human-to-human transmission of the novel coronavirus.”

From my understanding that Tweet was deleted. With all the contradicting stories coming from the media, the WH, WHO, social media, I’m going to stick with facts and not twisted agenda pushing.
No, that's wrong. WHO essentially never encourages travel restrictions, their whole philosophy is that open international collaboration is crucial (that's why the W stands for "world"!). At the height of the Ebola epidemic, they didn't call for travel restrictions to Africa either.
Except it's not actually fair, which some people may not like.
When I started at my current company we had desktop PCs, went home, and used a VPN to dial in.

They got rid of the desktop PCs and gave us all crappy laptops (they took a few years to catch up in power to what we had) and the argument was they could not ensure a secure environment on random home PCs. They were probably angling towards a hot-desk setup too but most people have a dedicated desk still.

I definitely preferred the old setup. I just struggle do any meaningful work at all on a laptop, I need to plug it in to a screen but I can't dedicate that space so normally just put up with it rather than unplug my home setup.

They do provide docks in the office but unfortunately a few different generations of HP laptops are around so you might need to search for the right one.

I work at a very large IT org (1000+) and the only way I have ever seen anything change substantially and persistently was when the change was introduced and made it far easier to do the right thing. Ultimately if you want people to do the right thing you can't force them into it, you have to make them want it.

It seems to me there are lots of opinions on how to change an organization or introduce improvements but ultimately if you aren't making people's lives easier, making them want the change you are trying to bring about, you'll find it almost impossible to succeed, human inertia is just too great.

Hey, Dave from lambda store here, in the short term, we plan to support ACL of Redis 6. Also in the long term, we are planning a version which will work on customer’s VPC for the enterprise customers with high security requirements.

Yes, that's how I interpret 'no clear evidence from preliminary investigations'.

The relevant timeline: Li Wenliang (a doctor in Wuhan) blew the whistle on Dec 30. 4 days later he was harassed by the Chinese police for "spreading rumors". On Jan 8 Li Wenliang was infected. On Jan 12 he was put in the ICU. On Jan 14 WHO denied human-to-human transmission.

Li unfortunately passed away in early February.

And by the way, there were warnings from Taiwan about human-to-human transmission very early on, which the WHO ignored: https://www.ft.com/content/2a70a02a-644a-11ea-a6cd-df28cc3c6...

Hey Dave from lambda.store here, thanks for trying our service, appreciated. We would like to hear more feedback If you play with our product further. For your TOS note, we can say that we are applying GDPR practices and storing personal sensitive information requires extra procedures, that’s why it is not allowed for now. In the future, we are planning to obtain security certificates(like soc2) then we can revisit our terms. again thanks for your comment!

Imho, this is where the phone company should be liable. If I let people masquerade as other users in my software, it would be a critical security bug and I'd be in deep trouble. But we just accept this crap from phone companies.
I can understand the code and if all you function does is this 2 statements I guess it is ok. Myself however I would not write any code of meaningful size in this style.

If however I was only using C and nothing else maybe I'd be catching this bug myself, one never knows ;)

Wire the powerwalls together inside the train and join them to the train’s electric drivetrain. Now you have increased range in your locomotive battery pack, instead of needing direct power from the grid or diesel to burn. Since the train in this metaphor is natively electric (like most existing trains with diesel generators powering an electric drivetrain), the same rails that power the train can charge the powerwall near the generator or discharge far away from the generator, all without the train stopping.

Not relaxing restrictions will also kill people from increased domestic violence, from depression and suicide due to business failure, unemployment, homelessness, etc, and from poor health due to inactivity.

I have a desktop PC at home in a home office. My wife is right near me.

I think this is probably a problem because I also play games on it so the room sends very mixed messages to my brain.

I help with a small business so have to use my PC for that. With my day job I have a laptop provided and do move around the house to get a mental disconnect and help me focus on some tasks. The problem is it's not a great device for stuff like in-depth research, I really want a big screen for that, so usually have to use the PC and get distracted.

I really wonder about all these services that eat into the layers of implementation that organisations usually do in house, but at the same time quick form a complex web of lock in that prevents you ever leaving Amazon. It seems to me that these services are very seductive but there are very few cases where it's truly in an organisation's long term interest to adopt them. At best, use them as a quick interim solution to bootstrap what you are building and then use that as your requirements for an open source or at least vendor-neutral equivalent.

Curious what the HN crowd thinks about this issue?
"isolation measures for at risk groups" sound so easy. First, isolate the obese. Hmm, 30% in America so 98M. Next isolate diabetics. Roughly 35M. After this, isolate those with heart disease and hypertension. 30% in the US, 98M. Old people? 32M. Naturally there's some overlapping in these groups. We'll be generous and say that 98M is the lower bound.

How on earth are you going to isolate 30% of the population?

> The WHO denied human-to-human transmission even after Taiwan told them about it

I don't think anyone on HN needs to be told that "there are no clear evidence of human to human transmission" is not the same as "there are evidence that human to human transmission is not possible" which is how everyone is trying their hardest to interpret it as.

> even after Taiwan told them about it

Do you have a primary source about it? Every time someone references it, it's an editorial obfuscating the embarrassing primary source of Taiwan's "warning" email from December 31 which reads:

"News resources today indicate that at least seven atypical pneumonia cases were reported in Wuhan, CHINA. Their health authorities replied to the media that the cases were believed not SARS; however the samples are still under examination, and cases have been isolated for treatment.

I would greatly appreciate it if you have relevant information to share with us.

Thank you very much in advance for your attention to this matter."

I am dead serious. Powershell should replace (bash) shell scripting under any Linux.

I find shell scripts terrible, I've learned to switch to Python quickly, despite the overhead.

Powershell is very command-line friendly, with easy tab-completion of commands. I've worked with it extensively on Windows, creating large worklflows with it, it's very nice.

Powershell even has a unit test tool called 'pester' which is funny to me because it means 'bully' in my native language.

You are simply ignoring the responsibility of the vaccine maker of potentially not going through the adequate steps.

A better equivalence would be the question, how should your hypothetical army be equipped and trained. And would the people doing/deciding that be responsible for the choices made.
I would understand you saying, it doesn't matter we are under attack.

> there are always new users discovering the systems

Software engineering turnover rates can be high, like 13%/year [1]. Add to that engineers who internally switch teams. New users is a real concern.

In this case, it sounds like a custom deployment tool, so even engineers with good experience at other companies may not find the feature. Good team on-boarding and documentation is important.

I think code review should catch something like this. Even with the high rate of new users, there should be enough experienced code reviewers to catch the issue.
