How accurate are these, anyway?

I run a Luftdaten module myself (with SDS011 particulate sensor), but with no government meteorological station next to me, I don't really have a reference point. All I can say is that this SDS011 spews out some numbers, and when testing indoors those numbers got higher when I turned on my air humidifier. I have a similar concern about DHT11/DHT22 - it's a random small box I got mail-ordered from China, which purports to tell the temperature and humidity of air. But again, those are two arbitrary numbers I don't have anything to calibrate again.

Just using these sensors and trusting the results is an accepted practice in DIY electronics community. But I keep wondering - are those sensors actually calibrated, or it's that people don't really care if they get garbage results?

(Related, it's also my number one complaint against a particular air quality startup in my country. They rent out air sensors which you can't inspect (there are contractual penalties involved), and they happily market their map as a vital tool for air quality, but nobody really knows what sensors they're using, and they don't even bother to put error bars on the values they show. I mean, I thought including measurement error is how adults behave.)
For those not wanting to wade through this, the thesis seems to be "...Stoicism caught on among Roman elites because it was the one form of philosophical guidance that didn’t urge them to renounce wealth or power....can be used to justify the idea that the rich and powerful are meant to be rich and powerful, that the poor and downtrodden are meant to be poor and downtrodden, and that even the worst actions are actually good in an ineffable and eternal way. Such claims can be used to justify complacency, social callousness, and even exploitative or destructive behavior."

I love philosophers, history, and philosophy. I consider myself an existential stoic. (How I reconcile these philosophies I will save for another day) The problem I had with this essay is the same problem I have with a lot of philosophy: it takes itself far, far too seriously for my tastes.

Do the rich adapt stoicism because of the underlying metaphysics in much the same way that powerful Romans did? Did powerful Romans even adapt it in this way, or are we left with various interpretations depending on which sources we use? More to the point, when you pick up a philosophy, decide you like it and want to apply it in your life, is this decision akin to adopting a new religion, becoming part of a cult? Or is it more like entertaining some useful concepts that you play on playing with to see how useful they may be to you?

It's not a facile question. If we adopt philosophies in the same we adopt worldviews, then the history and inner conflicts can be quite important. If, however, we adopt philosophies in the same we might pick up a grape Slurpee at the local seven-eleven, then not so much.

Philosophy tends to take itself far too seriously, and it tends to take a few really good ideas and beat the living heck out of them until they don't work anymore. I doubt the thesis here. Or rather, it's overstated by a significant degree.
This is actually valid. You can absolutely dispute a crypto currency just like you can dispute a cash transaction.

Except that only holds true when you perform a crypto transaction in the same way as you do a cash transaction, for local services. The moment you do it for something remote, you will run into all sorts of issues.

If a merchant in my country fails to deliver on a cash/crypto transaction, the dispute process is easy.

If a merchant in another country fails to deliver on a crypto transaction (posting cash is a whole other topic that we'll avoid here), what dispute mechanism do I have? International law is a minefield.
Does anyone know what the typical salary of this kind of software developer is? I hope they are paid several times more than I make as a web developer.
I agree. But most of the time it just sounded like the typical deep female computer voice that scifi has used for decades.

On the subject of stealth, I've always wondered if stealth aircraft could not actually be detected fairly easily.

True, stealth aircraft have an extremely small radar cross-section. But I'm guessing they also have very specific and recognizable radar signatures, with the proper signal treatment, despite high noise ratios, their signatures could be isolated. And they could also be easily identified down to the variant of aircraft.

This is a pure guess, not substantiated by anything, and I'm far from an expert or even an enthusiast in the field.
There is a strong need for financial education.

There is a small minority of Americans who won't have any retirement savings due to catastrophic illness, or a lifetime of inability to get a good paying job, or some other factor. But this number should be very small. Everybody else should be able to accumlate money for retirement.

To save for retirement takes discipline and means forgoing things today to save for tomorrow. The benefits of saving for retirement must be indelibly impressed into people's minds for this to happen.
Turkey-Based Prisync Acquires Spotlite
I'm an Economist subscriber and so read it most weeks, but honestly their charts and visualisations are often terrible. I think they could read a bit of Tufte and reduce chart junk as a starting point. This article does make some other good improvements though, so there is hope.
Interesting read, but he's still wrong.
DAML and Container Image Manifests
It's about time management and prioritizing what's important. Are there exceptions like the single parent with 2 hour each way commutes working 8 jobs with 5 kids? Sure, but in general common folk have time to do all the things you list. Throw in IF and they can skip breakfast ;)

I know a single parent that trained for and ran a marathons while working full time and raising 2 kids. She was not up to date on whatever TV show was popular, but that's a good thing.

Time and food are very similar in this regard. People do not know what they are using and how much until they sit down and do a log for a week. If after logging they find their entire week is full with zero wasted time, good on them. They are already getting it done. But, most people are likely wasting tons of time watching TV, mindlessly scrolling on social media, and/or reading HN (yeah, writing this comment has already blown through my allotted HN time this morning).
Lisp is a better choice than most for the first compiler/interpreter, but I would recommend starting even further down the complexity scale with Forth [0] since it lowers the risk of running out of motivation/loosing track of the goal.

It's not exactly vanilla, but my favorite stack is still jQuery and Bootstrap. It's easy and fun to make things with.

Frameworks have advantages, but in a tiny team, separation of concerns is not a major problem. There's a bit of overhead in maintaining, debugging, and a large opportunity cost in learning. The whole "it's better to practice one kick a thousand times than practice a thousand kicks once".

In a sense, it feels much like drawing with an easy medium like pencil, instead of using oil. They're all good in their own way, but I like the raw feel of it, and it works just fine.
I’m with you. I’ve been enjoying the Watch 4 for tracking my workouts and calorie burn heuristics and general heart rate. I’m interested to see the ECG results.
China opens its financial market as the US trade delegation arrives
When I learned Ada, I used the wikibook [1] and bought an inexpensive used textbook from Amazon. I have a basic competency of the language, and really like the quality of the compiler toolset, the type system, the "DIY" OOP (as I call it), and the packaging system. My biggest issues with it are that bindings for databases, graphics libs, and web development libs are few and far between and usually just a lonely github repo. But, as another positive, writing bindings to C libs seems pretty easy [2], so someday I'll give it a try.

So, I must be missing something but all that re-engineering was to put a larger engine on the airframe but still have ground clearance, while on the ground, correct? What was stopping them from increasing clearance by increasing landing gear height? (And thus not impacting flight characteristics)
I’m not really planning to download it unless there’s a DR event with my local set-up.
Yup, in the UK it bugs me when I keep meeting people who introduce themselves as an 'engineer'. When I ask them if they do mechanical or civil engineering, then I usually get to say "ah, so you're a programmer, just like me".

One thing I did sometimes like about being in Austria is the obsession with academic titles they have there... if somebody is a qualified engineer, they invariably use "Ing" as a title in place of "Mr" or "Ms"; people with two doctorates (not uncommon) really do call themselves Dr Dr So-and-so.
It's almost as it is an inverse pyramid scheme: you have a lot of stuff, so now you have to convince a lot of people that what you have is worth something, by giving them the stuff.

Now they are interested in stuff being valuable too.

I've never heard anyone use the phrase "under the table" unless there was money being exchanged for services without going through the proper channels. Your understanding was spot on. This was a bad use of a very old phrase.
From the article.

That design decision meant the 737 MAX would tend to pitch up while accelerating.

So the MCAS was there to counter that behaviour by automatically pushing the nose down when it detected this nose up situation.

I'm posting this not because of politics. But of concerns when financial businesses have growing dependencies on China.

And everyone knows, China only cares about itselve.

What if, at some point in time, they ban the business and they have a lot of loans out that don't get repaid.

Since, it's only the financial markets. I'm actually worried about this.
Mobile networks in the UK will, unless you ask and show ID, default to blocking "adult" content - ostensibly brought in for porn. This is schizophrenic at best, verging on brain-dead/bananas most of the time.

Porn sites are blocked as you'd expect. It's rare to end up on one of those unintentionally, barring typos / odd results in search. But...

archive.org is blocked. VPN companies were blocked until very recently - but not VPN endpoints. Image hosting sites are blocked on a coin flip - deviantart is blocked, imgur fine - both seem to have a similar level of adult content, the rest seem to be 50:50. Reddit, including any and all 18+ subreddits, and reddit image hosting are fine... So it goes on. It just discredits the whole process.

I bump into it far more often than I'd ever have predicted, and get annoyed by it regularly - yet I have never once, in a decade of mobile net use, tried to get knowingly to pornhub or whatever. Mobile phones are too small for porn. :)
If I can say it another, simpler way: I decide when and what I do with my body and what that makes me. No stranger’s perception nor insistence can change that. However, repeatedly being subjected to such judgements over subconscious or natural expressions of behavior, whether voice, gait, etc., is a vehicle for psychological harm, much like gas lighting.
Many rich and powerful are extremely ambitious. They aim high and get very upset when they don't get what they aimed for. The higher you get the less if your endeavors will succeed.

Yup. The reality of this industry is that most programmers are closer to the handymen you call to fix your faucet or lay floor tiles than to actual engineers. And we all have first-hand or second-hand horror stories related to handymen.
It's not pension. Everyone with an income pays into social security and how much is stated on your pay statement. Companies opted to replace pensions with a 401k so once the worker leaves the company, they are no longer required to pay more into it (correct me on this if I'm wrong). The 401k is market based so there's risk involved whereas a pension was guaranteed but even that is now based on the market so during the 2008 market issues, even pensions saw a dip in value (pension funds).
Win16/Win32, sure. Everything else, eg DLLs, I bundled known good with the app. Microsoft was notorious for slipstreaming changes.
> But self-discipline is much easier to muster in "easy mode", when your other duties are taken care of by an army of servants.

Self discipline is also easier when you actually work on your self discipline, plan your day, have a schedule, stay off your phone and computer when not working and so on. There are countless ways you can make your life easier and stress free.

Losing weight is a matter of eating healthy foods, using the stairs instead of elevators, taking walks during lunchtime, don't eat/drink sugar rich foods and drinks. Losing weight is obviously difficult when one has a medical condition that prevents losing weight, but when you don't it is a matter of self discipline to lose weight. Also taking daily vitamin D supplements makes a huge positive impact on ones mental and physical health.
The clerks at those stores often have no idea what they're talking about and just repeat things they've heard.

In this case, it's actually very possible that the clerk really thought that incredibly stupid statement about a product that the store was selling.

On the other hand, I've found that sales attracts and retains incredibly unethical people, too, so that's still a possibility as well.
Umm... these are corporations. They are owned by shareholders and exist for the benefit of shareholders. I don’t see any subterfuge here.
From the Wikipedia article you linked: "Man Booker Prize long-listed The Wake (2014) by Paul Kingsnorth is a historical novel written in a shadow version of old English telling the story of another resistance fighter in the fens whose actions are regularly compared to Hereward."
I like the slightly provocative title.

To the stoics themselves, wealth and power are indifferent: neither good or bad.

I say that the title is provocative because wealth and power often provoke people, as can be seen in this very discussion (here on Hacker News). Depending on where you come from and where you are in life, a phrase such as "rich and powerful" may call forth the negative stereotype of evil wealthy people, or it may call forth the positive stereotype of Hacker News style entrepreneurs.

It is much easier to be indifferent to wealth and power if you already have it.

My take on the supposed rise in popularity of stoicism is not that it appeals to the "rich and powerful" per se. I do however think it appeals to people who have found themselves in a situation when they no longer have obvious things to live for, which is certainly the case for these people.

If you suddenly find yourself with free time and autonomy, philosophy is a pretty good thing to fill the void with, I think.

It already is to a certain aspect. Medicare and social security can be considered "socialism." Which is why there's a certain group that wants to do away with it entirely.
I do the same with CBC. The offense I hate the most is when they chop off a bar chart so one bar is twice the height of another but the actual value is only like 5% higher.

The file manager would ask you to pick (using the Android UI, via SAF) the directory where you had downloaded the zip, then everything would work the same.

Alternatively, the app can register itself as opener of zip files, then it could extract them freely to its own private directory (without asking for permissions) and let you list and upload them.

इस बीमारी को अर्श, पाइस या मूलव्याधि के नाम से भी जाना जाता है। इस रोग में गुदा की भीतरी दीवार में मौजूद खून की नसें सूजने के कारण तनकर फूल जाती हैं। इससे उनमें कमजोरी आ जाती है और मल त्याग के वक्त जोर लगाने से या कड़े मल के रगड़ खाने से खून की नसों में दरार पड़ जाती हैं और उसमें से खून बहने लगता है।

कारण-कुछ व्यक्तियों में यह रोग पीढ़ी दर पीढ़ी पाया जाता है। अतः अनुवांशिकता इस रोग का एक कारण हो सकता है। जिन व्यक्तियों को अपने रोजगार की वजह से घंटों खड़े रहना पड़ता हो, जैसे बस कंडक्टर, ट्रॉफिक पुलिस, पोस्टमैन या जिन्हें भारी वजन उठाने पड़ते हों,- जैसे कुली, मजदूर, भारोत्तलक वगैरह, उनमें इस बीमारी से पीड़ित होने की संभावना अधिक होती है। कब्ज भी बवासीर को जन्म देती है, कब्ज की वजह से मल सूखा और कठोर हो जाता है जिसकी वजह से उसका निकास आसानी से नहीं हो पाता मलत्याग के वक्त रोगी को काफी वक्त तक पखाने में उकडू बैठे रहना पड़ता है, जिससे रक्त वाहनियों पर जोर पड़ता है और वह फूलकर लटक जाती हैं। बवासीर गुदा के कैंसर की वजह से या मूत्र मार्ग में रूकावट की वजह से या गर्भावस्था में भी हो सकता है।
My understanding is that Apple still doesn't implement some new web standards, so yeah actually.

Ultimately, if a vendor refuses to support something, it doesn't matter if it is an 'open standard' or not. The openness means absolutely nothing in this instance.

Real analysis is not actually that hard, you do however have to learn a bunch of notation, concepts and processes before you can grasp things. The people who struggled with it at my course (different country, similar content I suspect) were, entirely unsurprisingly, the people who didn't attend all the lectures.
> This is a post-colonial battle still being fought, and India's wish to shed its colonial shackles deserves to be respected.

Calling it a 'battle' that is being fought and 'shackles' being shed and all is a bit bombastic. And kindly do not purport to speak for all Indians.

What's next? Are you going to fight the battle to call Patna Pataliputra? Rajasthan Rajputana? How far back in history do the really real names lie?
Syntax is a sore point for me, but as a polyglot, I push through my bias. I am learning Spark instead of full Ada, and instead of Rust for a project simply because there is a lot of precedent and libraries for what I need to do - a machinery controls package with high-level safety. I do like Rust though, but I am also playing with Zig for good measure.
That is a compelling argument. But, if you Google for "heart cells don't regenerate", you find that it does appear to be a thing experts believe. And you find article like this that attempts to explain why heart cells can't regenerate: https://www.sciencedaily.com/releases/2011/08/110809092102.h...
The bit you put between brackets '(intended)' is the key here. What they intended was one thing, what they got was an entirely different thing. The stabilizer being as large as it is and the degree of authority afforded the MCAS system could cause the tail plane to deflect to a degree that the stick could not overcome it at all, the elevators are simply not large enough to counteract a tailplane that is trimmed purposefully the wrong way to the maximum deflection, in part because trimming the tailplane wrong also limits elevator effectiveness.
