The true gem is the story shared in the first, top rated comment on reddit. An engineer found a side gig to help others that passed interviews to do their job (not knowing this initially, but realized soon). Basically a contractor who via a fake interview got a dev job in a large corporation is subcontracting specific programming tasks. Interesting world we live in.
Sleepyhead probably saved my life (literally) when I couldn't get any sleep doctors to take my condition seriously. I can't thank him enough for his contributions.

The software is quite good, too, with a better UX than a lot of enterprise apps that I use on a daily basis. Might go to show how one person's ownership can lead to the creation of great experiences in ways that the lack of ownership often found in large software projects does not.
There exist more articulate writings on this subject. Chloramines are formed when urea (pee and sweat) meets chlorine [1,2]. It contributes to athlete asthma [3,4,5,6,7]. It is an identified occupational health issue [8]. Chloramines are a concern with aquatic facility operation [9,10]. One way to help is to use UV filtering [11,12]. I believe the solution is just better aquatic center ventilation [13] especially moving air across the water surface [14].

Many years since I had relatives in agriculture and horticulture, so I may be embarrasingly outdated.

Monoculture tends to encourage everything we don't want. Needing fertilisers or rotation, pesticides, disease has many acres to spread easily through etc.

There's good organic and bad, and efficient and inefficient., but look into polyculture[1]. An old mixed farm would mix crops and sometimes livestock in the same space. The yields were lower, but there were often more yields across the farm to compensate. Thus the yield difference is often not as advertised. Sympathetic planting could actively reduce likelihood of disease and pests. Not everything scales to large farms.

It's also expensive because it's expensive. People expect and treat organic as a premium product. Supermarkets charge accordingly, in no small part because they can. If less industrial approaches to agriculture became widespread, prices would fall. Though unlikely to remove the difference completely.

This has been well-known by swimmers for a long time: chlorine itself is pretty much fine for you. It's the chemical reaction of chlorine with waste products, including human waste, that produces toxic byproducts and the concomitant "pool smell."

If you swim in a well-maintained pool (e.g. one of my university's competition swimming pools), there's no "pool smell."
Most of the people I've talked to aren't crazy alien conspiracy theorists so I can't really comment on that brand of conspiracy theorist. Honestly my main experience is
the standard 9/11, global warming, and Obama conspiracy theories (which were incredibly racist) from the early to mid 2000s and those were all pretty similar to modern theories and at least for my father in law and his friends were definitely from Fox News and talk radio.

Edit: a good example to me was the start of the birther movement, which is a quinessential modern conspiracy theory to me, and I remember that as talk radio and Fox News.
It's Never Late to Learn Coding
I wrote this piece on how I taught myself to code and launched a complete product, 18-months later. I could have done it faster if I didn't have to work for clients. I mostly had to learn to code, it wasn't a choice so I could tell everyone how I did it on my own. I couldn't hire any employees. I was cornered with lack of finances from investing all my savings on a previous product which outpaced itself with expenses faster than it could grow.

I hope it inspires you to learn coding and make a product of your own. Starting could be hard, but once you get a hang of it, you'll run faster.

This is like that article that talked about increasing extremist political videos being recommended depending on your views habits (Youtube).

I understand, no data can create predictions. But tastes are so depending of the context you grow up in that it is normal not to be able to predict that. And that uniqueness is what makes a person great.

No idea what 'SleepyHead' is but I understand the sentiment. I've felt the pain from the perception of not getting anything back after you've poured so much of yourself into a thing. Especially when it's for free, the lack of support starts to feel like ingratitude.

It might or might not be true. People might actually appreciate what you're doing, but never explicitly say it. However, after a certain point, your mind becomes so toxic and awful that nothing will convince you otherwise. It's really better to walk away than become a shitty, bitter husk IMO. Good luck, guy!

It is. You need to restart the adblocker VPN when done (at least DNS66 operates this way).

Thanks. That sounds like LCA in terms of testing the labour market, though. What did you mean by "the USCIS trusts the employer's word"?
My understanding is that the reason it started replacing other services is that there's a dependency graph that ends up pulling them in, and very early in the boot process depending on configuration[1]. That, and in some cases the available solution did not support their needs[2] (which might have been solved better through upstream work, or maybe not, if the targeted project was slow or unwilling, I'm not sure).

If my memory serves me well, it is not chlorine, but the product from hypochloric acid[1] and urea/urea-derivatives that that make eyes hurt. Although, I don't know if they use Cl2 as reagent here.

> Unfortunately, my provider (EE, UK) throttles UDP traffic something rotten

Interesting. I've not noticed performance issues beyond those expected due to signal quality when using work's VPN over a tethered phone using EE. That VPN is using OpenVPN with a UDP transport. Then again it doesn't get used for anything with high throughput so perhaps they only throttle when it looks like bulk transfers are happening or the effect of the throttle just isn't apparent for my interactive use-cases.

> or have you found a way around this?

If they are throttling UDP for your use case then you could try a TCP based VPN (OpenVPN supports this), though there are potential issues with layering TCP inside TCP particularly on high-latency connections so this is not usually recommended. Might be worth a try to compare/contrast though.

I have a play with mine both ways when I finally get round to adding it to my current phone (mainly to use the network level ad-blocker running at home) and see if I can see a measurable difference with each variant.
You lose binary portability though: what is you can write you image processing code such that it operates well whether your SIMD instructions is 4, 8, or 16 wide? (or more).

Then shipping this binary for mobile phones for instance would take advantage of the wider register available on high-end device while working well on more modest CPUs.
The Scots leid branched off from Middle English tho, well after 1066. There’s plenty of French in the bonny north’s tongue. Scots Gaelic was the language untouched by the Normans, and quite a few words got transferred into Scots when the Gaelic-speaking populations were forcibly migrated into Scots areas.

Two innovations have revolutionized my life—CPAP and Sleepyhead.

I volunteered to do a sleep study at the famous Stanford Sleep Clinic some 15 years ago hoping that they would tell me I’m superhuman and don’t need sleep. They came back and told me that I sleep very poorly.

CPAP machines are (finally) wonderful, but the manufacturers don’t share any of the data that their machines collect other than basics like hours slept. For those of us with the intellectual curiosity to actually double click on your sleep numbers, Mark’s work is invaluable. I have over 1,500 nights of sleep logged in Sleepyhead...I learned the perils of drinking wine with dinner, the value in tucking in at the same time every night, and which masks work best for me—just to name a few benefits.

I use sleep medicine to improve my life, the same way that I use a screwdriver to tighten screws—which is to say, I pay no attention to the sleep-apnea forums and I suspect most users are the same. I’m sharing all of this here in case Mark by chance frequents this forum—and hopefully if enough others like me discuss the value that this free product creates every night for so many millions of users, he may reconsider. I for one, would gladly pay for a Sleepyhead subscription if that meant continued support.

Thanks Mark, your work is invaluable.

>What if someone steals your laptop and decides to see if they can get any sensitive info off of it before they wipe it and sell it?

That's what full disk encryption and (eventually) hardware security chips and the like are for. It's not a threat model that has anything to do with password managers.

>Probably not a common scenario right now

It never can be, that's the point. Physical attacks simply do not scale like purely online attacks do, let alone attacks on centralized single points (ie., a central password database).

>but if this threat goes unfixed for a long time and tools become available to automate the attack I could see it becoming a problem.

What? What tools "automate" stealing your notebook?? And also breaking through whatever physical security it has, like TPM or Apple's T-series chips or even just plain soldered on storage/memory/everything? The latter make repairs more of a PITA but they also make physical attacks significantly more difficult, even stuff like cooling memory and swapping (and encrypted memory based around tamper resistant security chips is a potential thing too).

My first question is always the same: what problem is the Blockchain solving for your business that cannot be solved using another technology?
Netflix is doing this at scale for all the content that it is on its platform, where the audience is the number of Netflix member that have watched (or will watch) a tv show, movie etc. There are limits of predictions that are reached quite fast. For example, how much money you spend on the production for an original show is the best predictor of the audience (more money spent means more promising plot and actors and directors, more marketing and so on). All the fancy AI, Deep whatever are largely irrelevant and a waste of time and money, but can be sold very well internally and externally, at least for a few more years.
I strongly recommend this simple flowchart as a first-pass heuristic for whether you've found a good use for blockchain.

Creepily accurate, This is amazing.
LBRY uses a database, that everyone has access to, to store metadata related to digital content and provide pointers to a more traditional decentralized P2P network like BitTorrent. The blockchain also provides publisher identities, human-friendly URLs (e.g. lbry://@MinutePhysics/magnetic-levitation), and a payment mechanism.

This decentralized db allows anyone to access the data without relying on one source.
Perhaps "underlying" cause was meant / as a symptom of something else. Unrealistic demands with high pressure for results may lead to cultures of misconduct for instance. If the policies lead to the behaviors getting rid of the result won't fix it.

> Only (about) 11 percent of Chinese land can be farmed. Most of its tremendous land mass is inarable, degraded by erosion, salinization, acidification, industrial effluent, sewage, excessive farm chemicals and mining runoff.

The figure for the US is 16.6% as of 2011.

The difference comes mostly only from the fact that a lot of China's West half is either arid, mountainous, or both, despite the author's hysteria.

Show HN: Crowd Sourced Knowledge Sharing Platform
Hello everyone,

I’m the creator of Jouho, a content exploration platform.
The “Taste engine” used by Pinterest was a major inspiration behind building this platform.
Jouho can be viewed as a Pinterest for links that contains good content.

Search engines today are extremely good at serving links that:
- Have the right keywords
- Have good SEO
- Have a high number of quality backlinks

Jouho takes a different approach to search.
The links shown are knowledge pieces that contain good insights around a topic that a user searches for.
Similar to how Pinterest shows related topics, Jouho harnesses the power of a knowledge graph to show related topics allowing us to explore search queries in different contexts.

Jouho relies on users creating collections and bookmarking links into them to seed its search index.
Currently, there are over thousand links indexed across topics like Data Visualization, Design UI/UX and Frontend Development(react, redux, vue).
As more links are saved by users the graph and the search index will be remodelled periodically to incorporate the new topics and links.
The search relies on a mix of Natural Language Processing algorithms to identify relevant content for a query.
The knowledge graph will get smarter as more links are saved and more relations between topics
will be identified.
Thanks for trying it out.

You do realize there's arguably at least two billion people who through no fault of their own will never, ever succeed, no matter how hard they try?

You're born in the middle of Tibet as a persecuted ethnic minority. You're on a tiny island nation with no economic future. You're from a part of Africa that's seen nothing but civil war interspersed with famine.

You can do everything right but the deck is so stacked against you there's no winning move.
It gets uglier, if the person who wrote this added in an underclocker.

https://hackaday.com/2019/01/04/underclocking-the-esp8266-le...

Long story short, underclocking the ESP12 compresses the RF envelope for 2.4GHz . It also means the RF energy is in what looks like 1/3 a normal 2.4GHz channel.

The awesome side effect is that this device's SSID is completely hidden from regular 2.4GHz radios. You need another ESP12 with the same underclock ratio... and then need the SSID (if hidden), and the password.

You'd be able to find it using an ADALM-PLUTO. It'd stick out like a sore thumb, but it still wouldn't make sense what's going on unless you build a decode stack in Gnu Radio.

The answer is "Not known". A decently skeptical article. One excerpt.

"When scientists have collected long-term data on insects, they’ve usually done so in a piecemeal way. The 2017 German study, for example, collated data from traps that had been laid in different parts of the country over time, rather than from concerted attempts to systematically sample the same sites. Haphazard though such studies might be, many of them point in the same dispiriting direction. In their review, Sánchez-Bayo and Wyckhuys found 73 studies showing insect declines."

Start of next paragraph:
"But that’s what they went looking for! They searched a database using the keywords insect and decline, and so wouldn’t have considered research showing stability or increases."
There are people called Radical Feminists, that consider everyone that defines "woman" biologically and that wants to keep certain privileges to women only (e.g. sex-seggregated toilets) to be a "TERF", and proceeds to shame them and misrepresent their position.

Chlorine Gas = Cl2, which is generated by electrolysis of NaCl in a saltwater pool setup.
As a longtime swimmer and water polo player, my eyes have been absolutely wrecked by harsh pools many, many times.

However, I don’t think it’s pee. First off, every swimmer pees in the pool.

I have been a part of tens of thousands of man-hours in the pool and seen people get out to pee maybe three times.

I have been in the first games of the day at water polo tournaments and have seen them chlorine shock the water followed by everyone’s eyes getting decimated. To me, the devil is unbalanced chlorine coupled with the thick, thick film of sunscreen that develops in the water after a scorching day with hundreds of people jumping in and out.

You get desperate when your eyes get that destroyed. The classic trick is to fill a pair of goggles with milk and just put ‘em on for a few minutes.
