QR codes are no good if cell service is spotty with certain carriers. Recently at a distant restaurant, I scanned the QR, waited for it to time out, discover there was no cell service, find the free wifi, enable my VPN, connect to the restaurants wifi, wait for authentication, then open camera app and scan QR again, wait for the kindle app to open the PDF, only to be handed a paper menu a few seconds later...

I know how a menu works. I read the food, see the price, and order. Personally I want to relax at a restaurant and not troubleshoot for myself and others, all while increasing my stress levels.

One way to fix this might be to encode the full text of the menu within the QR code, instead of a link?

QR codes are handy for easing people into eating out again... but wow; it can be pretty frustrating. Something I find myself thinking about more, is how Technology really needs to be more reliable, and how we really need to consider all the edge cases, before we can begin to replace the simple items such as a menu, let along more complex systems....Rant: I want something that will work 100% of the time.
It's highly suspected that someone will pull the plug on this drug.
Spray paint over the QR codes.
At the same time the hostess asks "Would you like crayons for the toddler?", it'd be simple to add "We have a digital menu, but would you like physical menus?". Or even a put "Physical menu available on request" below the QR code.
In analogy, it would be similar to pointing bright flash light directly into the eyes, I guess.
Those are pretty moderate left positions. If you want extreme left, you need to go out into the wilderness where people want to outright abolish money and overthrow capitalism.

This feels like an odd statement. Surely a database being dropped all at once is about the loudest possible thing that could happen to a database-reliant application?
When this happened to me I decided to just tell my manager the truth. He honestly didn't even realize I was having issues and he reacted to it by firing me. Mentally, I was in a place where I was kind of happy that my suffering can finally end. On the other hand, if I had just kept my mouth shut I could've probably zombied my way through for a lot longer.
There's a system to being lucky. It's building your talent stack, and putting yourself in situations where luck can find you.

Normal childhood interests can lead to lucrative careers, if one decides to follow those interests. These days, that's only a google search away.

for all intents and purposes weed is harmless. In WA, most people that I know have tried weed and some of them are actually doing it on a regular basis. I have yet to hear of any [mental] health issues.

If you do something all day everyday you are dealing with something else and the drug is a way of escapism.
IMHO it should be like this: Read QR code next to dish. It executes order for dish, and subtracts set amount of Bitcoin (perhaps with a confirmation so you're not scammed).
>Adults should be allowed to have any mind state they want, as long as it doesn't hurt anyone else.

I mean, exactly the issue here is that if you allow all adults to take as much meth as they want, they will start hurting someone else indirectly.
Not true at all!

Many bars (that now call themselves "tap houses") have beer menus that are either only online, or printed in a 20pt font on a 54" LCD TV behind the bar.

It is super annoying to have to get up for each beer because the server doesn't know what #32 out of 70 is let alone which number is a lager, and then not be able to read the menu (because my eyes suck) until I'm leaning over the bar.

Super, super annoying.
Unless you are a visiting foreigner without cell phone service and the WiFi requires you to login with a working cell phone number, then you are in 没办法 territory.
That's not right either, your downside for selling puts is limited by the strike (worst case is you pay K for a stock worth 0). Short call positions are the ones with unlimited downside (worse case is that you get K but have to cover the cost of arbitrarily high priced underlying).
Reminds me of the time when TSLA MCap got bigger than Volkswagen + BMW + Daimler + a few othere and I bought OTM puts.

This was back when TSLA was at 160$ (800$ pre-split)
It would be really interesting reading an article on what you do different on what each part costs. Effectively how image hosting services work nowadays or if nothing changed in the past 15 years.
My biggest surprise in these comments is that people seem to have actually successfully used a QR code! I always assumed they were an iPhone only feature, so I ignore them.

I've read that the Android camera app is supposed to recognize QR codes, but it doesn't seem to on my phone.

That's a pretty huge leap. I'll regularly send check-in messages like this to my employees, both if their work does appear to be suffering, but also just literally to check in and get up to speed on where their focus is. And even in cases where work is suffering, my hope is very much to be able to resolve the issue! Getting fired does suck, but firing people also sucks. Not as much, certainly, but it's not like it's something you'd choose to do when there are alternatives.

So I turned off adblock, but I see no ads, even though you have some ad domains. Is imgflip pro the way you make money only? I tried again and all I saw is one banner ad, sometimes. Do you have more ads more frequently, or is it just a relatively minimal amount in general? What is the revenue split between pro & ads? For linus for example, it's about %26 youtube ads, https://www.youtube.com/watch?v=-zt57TWkTF4

How do you deal with moderation? Is it automated, I see you even have comments? Or is it just report buttons and your takedown form? How is the support load?

Talk about low value comments.

Why not?

Just because you don’t like it doesn’t mean it’s not actually better for some people and some situations.

This is obviously a decent use case for QR code’s; your comments seem just like you don’t like it, and you’re not interested in even considering any other option.
From a manager's point of view: This person just wants to know what you're up to. It's not a judgement, it's a simple query. It can be solved via additional communication. Probably best to do on the phone so there's no confusion but email works also.

> how can a company expect to retain employees/contractors if the only work available is the same tedium over a long period of time, and no way to change that?

Actually, once you've established that you're capable you can usually ask for assignments / work that interests you more. This also requires additional communication. Even if there's nothing immediately available, your manager will keep it in mind when looking forward to the kinds of work you express interest in.
I find paying via QR code to be much less convenient than NFC that is more popular in the west. Tap and pay is really quick, especially in countries like Australia.

I’ve tried Duolingo, Babbel, Rosetta Stone, Lingq and some others I can’t even remember the name of. First of all, you won’t learn a language using only an app. And you will need a lot of intrinsic motivation and grit which an app can’t help you with. That being said, the best app I ever used and still use is Lingq, because it guides you towards using the language in real life situations with a lot of context, and you can use their audio clips to learn in the car or during Sport etc.. The other apps only ever have you translate words and context free sentences, which is a futile approach.

The point is that the right likes to paint those positions as dangerous extreme left ideas, and a lot of the time when someone says "but what about the extreme left" they are talking about those, and trying to make the argument that they're not being taken down - so obviously white supremacists and covid conspiracy theorists deserve to be on youtube too.

Highly suggest a sub, he only writes about American monopoly power.
The best parts I found here :

> The Ring Doorbell, which is now owned by advertising megacorp Amazon, suffers from all of the same privacy problems described in my post about the Nest thermostat, but even worse. Like the Nest thermostat, the client software is a total “race to the bottom” one-size-fits-all garbage iOS app that not only looks bad, but is full of bugs. Also like the Nest, all of your data is hosted in “the cloud”, and a monthly ransom is required before you (“the customer”) are actually allowed to access it. Worse than the Nest, however, is the fact that the Ring doorbell actually has a camera and microphone built-in, so video and audio feeds are also held for ransom in “the cloud”, and are shared with any interested party, sometimes even without your permission.

> Just like many other Internet of Things products, the Ring has also been subject to multiple disastrous data breaches, meaning besides law enforcement agencies and advertising partners, many Ring customers’ private data is now also in the hands of malicious hackers, who may in the future offer ransoms that are much harder to refuse than the one offered by Amazon.

Yep, in the ideal world. But:

A- major proportion of civil/structy engineers are going into retirement, their numbers not supplanted by new blood. It's just not a calling anymore.

B- USACE redacts their dam and bridge inspection databases by zeroing out inspection dates. They're obviously managing the external perception of this process, and internally prioritizing best they can.

C- they only have ~32k employees, of which there are only so many pertinent engineers, handling 200k bridges and 90k dams. Overwhelmed is an understatement. Then there's the budget situation.

D- then there's the buildings.
I actually get these when I'm over stimulated before bed. I used to take add meddicine in college but would fall asleep after 6 surges and some adderall. And then my brain would just be wheeling away on nonsense. Rarely do I dream like this when I have a fever, usually I'm just out.
you are always explicit about performing a numerical vs string comparison

But the values which you compare do not have to be of the same type, and it does not end at scalars (which are really ephemeral in their exact typing even in native API, see perlapi). Basically it has two flavors of ==, each with its own preferred coercion. Perl also has contexts, e.g. boolean and scalar which can operate on lists and hashes (@list == 5). While the form is different, semantics are similar.

The problem is when you do them by accident because of a mistake in your code, and the error slips through unnoticed, doing the wrong thing

If your string array contains some [[0]] by accident, I’d say there is not much left to do anyway. === doesn’t report this either, it only has narrower trueness, which may decrease or increase an error surface depending on how your conditions are spelled. And to be clear, I’m not arguing against using === in places where identity^ or strict equality check is necessary or desired (you may desire it most of the times and that’s valid). My concern is that (a) everyone blames == anywhere, for completely zealous reasons, (b) I have to type a poem to test for null and calm down someone’s anxiety.

^ I know it’s not exactly identity, but is close enough for practical purposes

When is the last time you knew of someone becoming blind from a poorly made moonshine? Legalization works for one of our most widely available and life-ruining drugs, why wouldn’t it work for the others?
According to the Maryland tweet it was “several”. The others referenced “exposure”. I suspect the media worried and reported the outrage about this far more than people took it seriously enough to do it.

Gonna sound harsh, but if you are dumb enough to ingest a poison on the say so of an obnoxious real estate developer, the world is better off without you. I’m ok with those folks removing themselves from the gene pool.
You're right. Thanks for telling me.
That’s a terrible analogy.

More like “if you were a bee keeper and got bit between 3 and 5 times a day and I introduced a more aggressive bee and you got bit 5 times two days in a row it proves it was due to the more aggressive bee”.
There's not much distance between current Docker behaviour and it calling a AWS/GCP/whatever API to route traffic to it. I predict some piece of sw, if not Docker, will be caught doing that in the near future.
As it happens, I know of no current system, free or proprietary, which can correctly generate arbitrary IUPAC names. All of them I have seen mess up things such as the nested enclosing mark pattern, stereodescriptor placement (and resulting enclosing mark modifications), lack of enclosing marks, lack of stereodescriptors for undefined stereocenters, lack of omission of locants, locants on substituent groups, use of multiplicative vs. substitutive nomenclature, nomenclature for aldehydes and polynuclear noncarbon oxoacids, cyclic phane nomenclature, italicized letters, and a myriad other parts of IUPAC nomenclature that the Blue Book specifies very clearly.

Putting that rant aside, most of these chemicals are small enough to have rather tame IUPAC names. As an example, these are the IUPAC names of the first five molecules I loaded (disregarding stereochemistry):

N-{1-[(2-fluorophenyl)methyl]-1H-pyrazol-4-yl}-2-[(pyridin-3-yl)oxy]benzamide
N-ethyl-1-{5-[(2-methylcyclopentyl)methoxy]pyridin-2-yl}ethan-1-amine
2-fluoro-N-{4-[3-(hydroxymethyl)azetidine-1-carbonyl]phenyl}benzamide
N-(8-methoxy-2H-[1,3]dioxolo[4,5-c]quinolin-7-yl)-2-methylcyclopropane-1-carboxamide
1-ethyl-N-(2,3,5-trimethylcyclohexyl)piperidin-3-amine

If you want an example of an absolutely ludicrous IUPAC name, I'd suggest the one I put onto https://en.wikipedia.org/wiki/Maitotoxin earlier this month.
Just a heads up to anyone reading this and feeling like they can't speak to their manager when they're having issues with burnout or stress: not all managers will react the way parent's did, and depending on where you live (pretty much any first-world country outside the US?) it may be outright illegal to fire you like that.

Its why every social network/content generation/attention capture architecture such as FB, HN, YouTube, Twitter et al cant function without a Like/Click/View/Upvote count publicly visible signaling status.

I worked in concrete repair for half a year, I mostly only used the jack hammer and angle grinder but I paid some attention.

Here is what I think I know:

When rebar corrodes it expands and that means even more air, water and salt can reach even further into the construction, meaning even more rebar is exposed and starts corroding. Edit: this probably weakens the concrete as well both because of exposure to the atmosphere and because of the cracking action but this last one is just an educated guess from my side.

How we worked was our foreman went first with an ultrasound device to detect the rebar and how much cover it had. He'd then sample the concrete by cutting into it, knocking out one side of the cut using a hammer and spray indicator fluid (I guess fenolftalein) on it. If the concrete turned pink it was healthy. You could measure how far out it was healthy.

If the measurements rebar was out in the damaged concrete we would expose it and apply protection before closing the wound. Sometimes we would also use a sledgehammer to adjust the rebar somewhat.

A number of factors influence how long concrete lasts before it needs maintenance:

- How far rebar is buried.

- The quality of the concrete as it leaves the mixer

- If the driver had lunch break or got stuck in traffic after loading the truck and added water to prevent anyone from noticing. Concrete starts curing immediately after mixing so you have limited time before it needs to be in the mould

- How well the concrete was vibrated to make sure it filled all gaps and that no significant air pockets was left

- How close you are to the sea

There's always someone on HN who knows something about everything and hopefully this was one of my turns to satisfy some of the curiosity for someone :-D

Edit: working with those older guys was really interesting. Seing a 70-year old bloke throw around tower lift parts that I figured I didn't have a chance of lifting. All the stories. The time I played with a bunch of cards and one of them askes to borrow it and started showing off crazy tricks; turned out he had a bronze medal from Nordic magic for juniors (and since he was now close to retirement and his hands were large and swollen I also got a chance to see what was really happening :-)

It was also the first place I know that actually practiced HSE. Others laughed but this team had 1-2% extra profit margin and I remember we got a nice bonus too. Ended up at around $15/hr which was close to twice what I used to get for much harder and dirtier work.

This was the spring of 2001. They liked me so when I left for school I got a nice job cleaning the work sites.
Windows 95 had a suggested retail price of $209.95

So I don't think the physical distribution was a large percent of the price.
A quote I often hear referred to in inspections: "It's not our job to catch you, it's your job to follow the law". If someone wants to deliberately avoid certain inspections, it's not that hard.

But your friend's story doesn't make a lot of sense. The foundation would have been engineered for the soil that was there, not designed, then tested to see if the soil matched. Even cutting corners, it doesn't make sense to do the steps out of order. So I imagine there's more to the story.
I had fun with Duolingo, but I can’t say it helped me learn anything. To me something is missing and the learning structure seems somewhat shallow. I’d not recommend it to someone that is serious about learning a new language.
Yes. Stocks can’t drop below 0.
But those languages are type-erased.
The US ADA requires reasonable accomidation, which is wishy washy, but lots of new construction nature paths in hilly terrain just have steps, because there's no room for a ramp and an elevator would be unreasonable.

Even new construction train stations don't always get an elevator to go over or under the line to the other platform... although they do get a long ramp and a ramp on the platform to load if the car floors are above the platform.

If these crossings are really in the middle of nowhere along muddy footpaths, I think you could get away with no ramp in the US, too.
My startup experience has been much better, but that’s because I was the cofounder and we’ve bootstrapped learning the lessons we need to learn to evolve vs what we think will make us blow up, people only think of the good blowing up, not the 9/10 startups who blow up and never recover.

I wonder how many startups that bootstrapped the author worked for and why they didn’t want to start a startup, that’s the only reason why I would join one because I’d like to be an executive/cofounder myself.
There were several pieces here that conspired to produce the unfortunate end result, the blackmailing attacker exploiting the broken perimeter security was just the last piece.
> true poverty is the lack of time to sit and think.

You might want to revise that. Here in Seattle, with homeless living in tents on the streets, they have plenty of time to sit and think. They don't have jobs. Many spend their days in the public library, surrounded by resources for sitting and thinking.
well... prepare for pedantry as people will lecture you about statistics significance and how this means nothing and how you don't actually know what you're talking about.

Well I'm late to getting in on this but that blog post made me laugh.
