How does this tech work? First they imply the LED boards are displaying all images, with the relevant ad picked up by the channel, but then they say it is inserted virtually.

At https://host.io we scrape every registered domain once a month, and make the meta data available freely over an API. You could use that to get a title for a domain (although not for a URL that's not the main domain), eg:

    $ curl https://host.io/api/web/facebook.com?token=$TOKEN
    {
      "domain": "facebook.com",
      "rank": 2,
      "url": "https://www.facebook.com/",
      "ip": "157.240.11.35",
      "date": "2020-08-26T17:39:17.981Z",
      "length": 160817,
      "encoding": "utf8",
      "copyright": "Facebook © 2020",
      "title": "Facebook - Log In or Sign Up",
      "description": "Create an account or log into Facebook. Connect with friends, family and other people you know. Share photos and videos, send messages and get updates.",
      "links": [
        "messenger.com",
        "oculus.com"
      ]
   }
See https://host.io/docs for more details about the API and what else you can do with it (eg. find backlinks to domains, domains with the same adsense ID etc)

The LED components listed in the research aren't listed on the web site as available. In addition, DigiKey no longer appears to carry the product line...

How am I gonna build short duration dosing unit for my shower without access to these parts.

For the purposes of getting this into the public domain...

I propose a small, waterproof, battery powered device that mounts to the shower wall which directs UVB radiation at 293 uM wavelength at the midsection of the user for a timed duration when activated by the presence of water

Activation is delayed once water is detected to ensure the user is actually in the shower. The time duration is limited to ensure nobody gets cooked like Ron Popeil rotisserie.

Everything is open source because everyone needs this


This is your friendly reminder to avoid the productivity hacking tarpit. It feels productive to think about productivity but oftentimes you're confusing movement for progress. I'll give two specific pieces of advice for people who are thinking about switching from methodology / app A to methodology / app B.

1. You might find something that B does that is just so difficult to accomplish in A, so you want to switch. But before you do, you should spend a week living with the difficult path to do that thing in A. You will likely find that learning the muscle memory to do that thing in A was actually the difficult part, and once you've overcome that hurdle it isn't difficult any more.

2. You might switch to B and feel that "now, everything is so organized!" However, it's very likely that you could have "switched" from A to A and you'd feel the same way. What I mean by this is that by switching, you've forced yourself to revisit all of your notes. If you forced yourself to revisit your notes without switching, you'd see the same effect.


But our goal isn't to get to a different station- it's to get from our origin to our destination. Previous studies of how people try to navigate have shown that people make heavy use of landmarks like parks which is why the MTAs map shows parks and major streets. Passengers also take into account how the train feels to be moving which this map doesn't convey. If the train obviously feels to turn left but the map doesn't show it, passengers get anxious.

His current map version: https://www.inat.fr/metro/new-york/

There are other problems with this map that demonstrate to me at least that the designer simply hasn't put as much thought into the design as the MTA. Some examples:

- Suppose I am on the Lexington Ave line and I want to know if my train (a 4 train) will stop at Astor place. I see a dot but no labels. So I start searching down the map for what the dot means. Eventually two green lines becomes one green line. What does that mean? I give up and start scanning upward and see that one line is for the 4/5 and the other line is for the 6. I finally have my answer. The MTAs map just tells me what trains stop at Astor place.

- This map implies that there are free transfers to the Path train when in fact there is not.

- This map implies that I can transfer between the 8th and 7th ave lines at Penn Station when in fact I can not.

- Is my Q train going to stop at 49th st in Manhattan? No one knows. That's just a minor design problem that was caused by a lack of space. The lack of space was caused by the designer's decision to illustrate lines individually.


He's referring to research by Nick Bloom, an economist at Stanford. They've worked together.

Ctrl-F management on his research page (https://nbloom.people.stanford.edu/research). In one paper, they randomly assign consulting services from a management consultancy to manufacturing plants in India and found a 17% increase in productivity.


I was advised to skip LASIK recently, as I was told I'd need it again when I got older and expose myself to all the same risks of a bad result over again. I instead decided to invest in much nicer contacts which has been life changing. I didn't realize there was that drastic a difference between crappy contacts(not even necessarily cheap) and good ones.

How do I know if I've got the good stuff?

I think a lot of people are surprised when they start using a prediction market or prediction registry and track all their predictions, not just the ones they remember decades later. (I thought Google was a good investment in 2005 too. I thought a lot of things back then, but I don't remember what else I thought.)

If it's possible, I think it's really useful to watch the users using the software for a while.

Monitoring user conversations about your product is absolutely critical, IMHO. Even if you don't directly interact with them, just seeing their chatter can be invaluable. Often times you, as the developer, will spot clues among their rambling that point to actual fixable issues. Meanwhile, these same clues will get completely filtered out and ignored if there's any sort of "user support layer" acting as an intermediary.

Sure, there's a lot of chaff to filter through. As such, its okay if you don't want to be the one interacting directly with the users 99% of the time. But simply paying regular attention to what they're saying is worthwhile.


This is why client & server side telemetry is so valuable.

People on this forum like to get all up in arms about it, but having it makes for a much higher quality end user experience, as you can see all the problems people run into. Not just errors, but bad ux flows, That cause people to bail etc. It’s really been invaluable for all the products I’ve worked on in the last 10 years.

Because yeah, most people won’t tell you.


I have an odd hobby: I keep a close eye out for people with busted brake/running/reverse lights so I can alert them.

One day I waited for a couple of minutes in a parking lot so I could tell someone his brake light looked like it was out.

He turned to his co-worker who had followed him into the lot to confirm. His friend told him it had been out for months and he just assumed he knew.

I don’t know what the takeaway is, but that mindset baffles me.


Larger cities are more efficient (in the sense of a lower required infrastructure per capita ratio) though. Not the article I wanted to find but most likely good enough:

If you care less about the pseudo-anonymous-but-not-really shared-IP aspect of using a VPN, and care more about the this-lan-is-sketchy use case, I have had good experiences with Algo [0]. You can just paste in an API key and spin up your own VPN on something like DigitalOcean. And it uses WireGuard!

No idea about those peaches specifically but wrapping vegetables in plastic generally reduces the environmental impact since it prevents them from spoiling.

" The fact that plastics do not break down, and therefore accumulate in our ecosystems, is one of our major environmental problems."

Not really. Landfills are safe and clean and plentiful. Ocean plastic is a problem, but comes almost entirely from intentional dumping. Litter is a problem, but it seems silly to assume that someone who cannot be bothered to put plastic in a trash can will put it in a recycle bin.

The real issue is the carbon footprint of making/transporting items, plastic or otherwise. I'd like to see how this compares in that regard. If this uses more energy than just making new plastics it will probably exacerbate a real problem (global warming) in order to help with a fake problem (landfills) which, unfortunately, is pretty consistent with modern environmentalism.


Was it a land line? I've noticed people who still have them tend to ignore them because they get so many spam calls.

The bug report says:

    by iframing popupfilltab.html (i.e. via moz-extension, 
    ms-browser-extension, chrome-extension, etc). It's a
    valid web_accessible_resource.
    [...]
    y.src="chrome-extension://hdokiejnpimakedhajhdlcegeplioahd/popupfilltab.html";
    // or y.src="moz-extension://...";
My understanding is that this should not work with the Firefox version of LastPass, since each installation of the extension is given a unique id which can't be guessed by web pages -- that is unless the unique id is made visible to web pages by the extension itself.

When I quit I ended up reading books and watching TV for entertainment. I literally read over a million words of fiction (Worm) in one month with the spare time.

It was a lot more fulfilling, and I'll remember that time. While in contrast there are few social media moments I'll miss.

I had to actually force myself to get back into social media. I'm not sure what the author here means by withdrawal; there was maybe a period of 1 week trying to get back in, but it was over quickly.

One big thing that happened was the number of consulting contracts went down significantly and never recovered. I'm quite Facebook active and used to get two interview offers a month. In fact last month I got a huge opportunity that I would have gladly accepted if I wasn't committed to anything else.

I'd be happy if social media was just wiped out and we went back to socializing on forums and IRC.


It seems like an education fail to me. Most people don't know the very basics of stats and we live in a world that's highly probabilistic.

It seems like something that should be taught alongside math from elementary school, not something you can maybe get an elective in in high school or college.


Just some personal observations, maybe relevant to recent misinformation topics, or maybe not.

Facebook, Twitter, Instagram etc. are all blocked in mainland China. Many people, especially those young and well-educated, use VPN to access them, have an account and follow world news and foreign celebrities sometimes.

There are popular and feature-rich counterparts in mainland, and most people prefer to have their daily sharing and discussion (including domestic politics) there instead of on social media based in US. Therefore most of the time, their accounts on Facebook or Twitter are mainly for reading rather than sharing and posting.

However, they might comment (register a new account if needed) on topics conveying a message related to China they strongly disagree (you could argue they are brainwashed), in a short period and coordinated way (they read repost from the same domestic website), through a few common IP addresses (the same VPN), with bad-written English (seldom practice writing before). But they are not bots and it's inappropriate to label these as the typical state-run misinformation campaign.

If you speak Chinese, you could find many discussions where ordinary people complain their accounts get blocked because of pro-China comments. e.g. https://weibo.com/1401527553/I32ryx2cu

Of course, these observations aren't necessarily contradictory with recent reports blaming China propaganda. I just want to show how some false positivity could happen, since there's some difference of the behaviour of China's users. Maybe a better algorithm is needed to distinguish them from government-backed activities.


Depending on the destination, if you have a “______town” for that ethnicity (or a nearby one that they’re not at war with), they’ll have some shops that can do far cheaper rates by consolidating.

A polish shop near me can send things to most of W. Europe for far less than the post office can.

The Ukrainian credit union near me can send cash to anyone in Ukraine pretty cheaply.


At least in the USA, this could in principle be fixed by ending the corporate welfare state. Old news, but All major industries like the beef industry get huge tax breaks, free water and other giveaways at the general taxpayer’s expense.

Fixing the corruption (both democratic and republican parties) in our our political would end up helping the environment a lot. That said, we have zero chance of fixing our corrupt political system. It will never happen, the elites have won that war.

One problem with reducing meat consumption is the general low skill level for cooking. Vegetarian food can taste better than meat dishes but you need skill and good ingredients. I have mixed feelings about Beyond Meat: my wife and I love the hot Italian sausage and burgers, but it is really not that healthy.


> killing plants by hoeing had drastic effects on soil fauna and functioning...In contrast, the effects of Roundup on soil fauna and functioning were minor and transient

Not 100% sure what this "hoeing" is, but we need to ban it now before it destroys the planet.


Plowing and the like is very out of fashion in big agriculture: the harm that hoeing is bad for the soil has been well known to farmers for a long time. (as long as I can remember which puts us in the 1970s) That isn't to say plowing isn't part of big ag, but they have found ways to plow that disturb less soil while still getting the benefits they want.

Glyphosate is a major part of big ag's anti-plowing system: by killing weeds they don't have to plow them up. Thus saving the soil. As a bonus, spraying uses much less fuel ($$$ for farmers, CO2 and global warming for the rest of us) than plowing.


If only it wasn't a likely human carcinogen (https://www.iarc.fr/featured-news/media-centre-iarc-news-gly...)

There _are_ security systems that stream a lower bandwidth zoomed out stream to clients reviewing footage, then sub in the full resolution version of the region being viewed when you zoom in, as a bandwidth savings mechanism - multiple 30Mpx camera feeds are impractical to stream around all the time.

Of course, they automatically substitute this when you zoom, they don't make you click "enhance", that'd be terrible UX.


I think you are confused. The “apartheid state” is in the West Bank. It’s “occupying terrorist state” in Gaza.

There’s no Israeli presence there other than Israeli water, electricity, petrol, money and occasional bombs.


Israel has relinquished all control of Gaza in 2005, and hasn't been an occupying force there since:

https://en.wikipedia.org/wiki/Israeli_disengagement_from_Gaz...

Gaza residents have been in control of their own fate since at least 2005. Unfortunately they elected Hamas, a terror organization, to be their government. Hamas predictably declared war on Israel:

https://en.wikipedia.org/wiki/Palestinian_rocket_attacks_on_...

Gaza Palestinians have fired over 30,000 rockets on Israeli civilian population centers since the Israeli occupation of Gaza has ended.

Current state of Gaza isn't occupation, and certainly not "apartheid". It's a small, weak entity waging murderous war on a much stronger country.

If a small nation fired 30,000 rockets on US civilians, the US would annihilate it. Israel is being merciful in Gaza. It has to, partly, because of anti-semitic propaganda such as you cited.

That propaganda is a major reason Gaza residents elected Hamas. Arguments such as "Israel is just a colonial force and should be eliminated" feed Gazans' fantasies of destroying Israel, which is Hamas's explicit agenda.

Hamas charter explicitly states that its goal is to kill every Jew in the world, and certainly in Israel:

https://en.wikipedia.org/wiki/Hamas_Covenant#Anti-Semitism

This is the organization currently in control of Gaza, elected by the majority of Gaza's residents.

It's convenient to ignore these realities and just paint Israel as the villain and Hamas/Gazans as victims, as you have done. Unfortunately, simplistic positions such as yours only support and embolden extremists like Hamas and feed into further violence, continuation and escalation of this conflict.
