Have you tried just dealing with it for a week? I find watches to be very annoying at first but after a while I don't even notice them.
> Also most tech people mostly turn off JS when they browse the web any way

any public stats that confirms this?
looking at your watch when you're talking to someone is a clear and pretty rude signal that they're boring you

Yes, some people take that very seriously :-O

The cognitive dissonance here is that DO want to give the low-quality contributors a t-shirt.

These are Indian students with good hustle and poor technical skills who market themselves as technologists. They're going to be managers making purchasing decisions at tech companies in a few years time, and they lack the technical sophistication to choose between DO and competitors on axes other than "I've heard of them"/"they have a good reputation"/"they gave me a t-shirt once". These customers are both more valuable and a thousand times more numerous than the ones capable of earning even a $10 bug bounty.

I'm generalising here, but hopefully not racially stereotyping too much.
> From an adversarial standpoint: If I have information about the random algorithm and the seed, I can make exploit it.

Randomised QuickSort as an algorithm doesn't have any random seed. It just uses pure randomness. (Specific implementations might use a pseudo-RNG.)

> This statement is imprecise. What is "worst case input" when speaking of "expected".

Oh, just the opposite! Speaking of 'expected' tells you exactly what worst-case to look for.

What I mean is that 'worst case input' by itself is not a-priori well-defined for randomised algorithms. Because you could eg have an input that worsens the 75%-ile runtime but improves the 25%-ile runtime.

By specifying eg 'expected', you make clear that you are talking about the worst case for the expected runtime.

> So yes, even the randomized Quick Sort has worst case of O(n^2)

The worst case over both input and random choices is O(n^2). The worst case over input for the expected running time is O(n log n).

Even more, for any input, even the worst case input, randomised quicksort has O(n log n) running time with 'very high probability', ie for any epsilon there's a big enough m and a constant c, so that with probability at least 1-epsilon, the running time of the worst case input of size n > m is smaller than c * n log n.

---

There's a different, but equivalent, way to analyse randomised algorithms that might be easier to digest for you, because it completely avoids having to directly talk about randomness:

Take your favourite deterministic machine model, say a Turing machine or a random access machine, and in addition to the normal input tape, give it access to an extra immutable one-sided 'random' tape that's pre-filled with binary symbols (0 or 1).

Everything is deterministic in this model.

An analysis of the expected runtime for the worst case input means that the adversary gets to prepare the input tape, but for the rest of the analysis we are analysing all possible contents of the 'random tape'.

For each possibility, there is one specific deterministic run. Talking about the expected (worst-case input) runtime just means that we are averaging over all possible 'random' tapes.

If we talk about the 95%-ile instead, that means that we are ordering all the runtimes for the different possibilities for the 'random tape' and taking the runtime of the 95%-ile. Still, everything is deterministic.

When you want to run this algorithm in practice, you sample from the space of possible contents of the 'random tape'. But crucially, the standard assumption is that you sample after your adversary has selected their input.

That standard assumption is in line with Kerckhoffs's principle in cryptography that the adversary knows your system, but that you are able to pick secret random keys at will.

There are other smart watches on the market and they don't seem to have a fraction of the users as the AW. Android Wear tries to look more like a normal watch but it ends up not looking as nice as a normal watch and not working well as a smart watch due to the round screen.

Pretty significant difference between "Facebook has done some research on changing moods" and "Facebook's product is changing your behavior."

It's overly dramatic in the way that I could say "Axe weilding man splits homeowners door uninvited" and "Fireman had to break down a door" and both are technically true, but only one is apt.

Facebook's product is influencing my behavior, technically, maybe, but it's a clumsy description made for the sake of drama. It's more accurate to say their product is targeted advertisements.

Why not just legalize the ransom payments? In a world where the IC was directed to fuck ransomware authors up, the money could be clawed back in most cases, or even fronted by the taxpayers as bait for CNE:

Apple Watch also has sapphire crystal among other material configurations; the configuration flexibility offers financial flexibility to consumers. There's also a difference between health tracking and fitness tracking, and in this regard I'm not sure Garmin will even intend to race with Apple.

This heavily reminds me of when Artists are offered to "get paid in exposure".
I routinely call them dumb TVs too, but they truly are the smartest choice. A TV costs $500, a Chromecast/Apple TV costs, what, $50? In addition to the price advantage of decoupling your TV from your "tuner," who is going to continue to support your device? Apple? Likely for perpetuity. Google? For some years at least. Samsung? Enjoy the only firmware that will ever ship for that device.

Don't buy smart TVs, they are practically stupid.
But you can't reliably get beat by beat interval data from a wrist PPG under normal living conditions. Also, to get breathing rate from beat intervals only really works when the parasympathetic nervous system is dominating, and isn't very observable in older people.

I think that art is just overwhelmed by fads. Artists are copying styles off of each other. It's true for any era. Egyptian drawings, medieval paintings, manga or holywood movies or internet memes.

Mimicking reality is rarely the goal that art is optimized for. It's mostly converging to local optimum of one of the current fads.

From what I have seen in the watch scene, a rolex is the equivalent of driving an enormous 4wd, its compensating for insecurity or to show off more than appreciation for watches.

Someone who actually likes watches is more likely to go with something premium from Seiko or Tag Heuer
This seems to be interesting, but I couldn't actually fetch android device information from the targets I have tried; THAT seemed to be private information that nobody should access, along installed apps.

Everything else seems just crawling/pinging for publicly available information.

Maybe the "Probable Location" is something a bit private if somebody didn't publish it in google maps explicitly... but then, it's not accurate.

It seems more of a tool for getting awareness of what information you're publishing on google, rather than something to actually fetch private info.
I did not know that "detail"; it totally makes sense though, thanks!
Browsers are a rather poor app execution environment thus there’s not much incentive for publishers to go that way, as given the choice the customers would largely prefer a native app to a similar browser-based one.

I built a data intensive website with Hugo and it’s horrible. Template engine is very bad. Hard to write reusable small functions (string manipulation, array manipulation, data extraction, mapping one form of data to other, filtering etc.). The fact that statements can’t be multiline is ridiculous.

Coming from Hakyll which just gives you all the power of Pandoc and a programming language, it was really a chore to work with Hugo. I’ll never use it again.
No one wears a watch 24/7. At the minimum they will take it off to shower since most bands tend to hold water for ages. A shower time on the charger is enough to charge the watch. The Mi band is amazing for the price but its a totally different product.
That looks gorgeous.
What do employee benefits looks like when everyone is working from home?
I agree with this. I'm worried about the probable location though, because I've realized that people tend to post reviews (even if it's a one-off) in a location where they live. All the probably locations it was able to guess, it was right.

If they were serious about that they would mandate and enforce open source along the entire Android stack that has root privileges on any Play-store certified phone.

Looks like Google has a mostly internal user id ("gaia_id"), once you've got this small identifier you can look on each Google related site for publicly available information relating to that user id.

Looks like Google is aware of it as the reference to gaia_id has been removed from Youtube pages source (Aug 2020), locked down public accessibility of photo albums (Sep 2020), and prevented connected email address leaks from Webmaster tools (Sep 2020).
In terms of raw compute, you're absolutely right.

In terms of understanding distributed computing and the failure modes that can occur, the GP's approach is definitely better. If you build distributed systems only testing them through virtualisation, you'll run into all sorts of issues that come from adding real world constraints that are otherwise masked through the virtualised abstraction.
I never found the sleep tracking to be useful. I get enough sleep and the watch doesn't tell me anything particularly interesting. I did it a few times and can see my heart rate overnight but it isn't something that changes day to day.
Yeah I really can't imagine that's true at all. I bet the rate of tech people turning off JS is like -- 1 in 100,000. But they _talk_ about it a lot, so it seems more like 1 in 100.

There are "golden visas" or residency by investment programs in many different countries, including some EU countries... Generally they require you to invest (much) more than 50K especially in developed countries... But there may be some opportunities there.

I think that Chile - safe, clean country with a non-toxic culture (and preferably a cool climate)- also gives visas to people with passive income...

And Estonia have also a 1 year Digital Nomad Visa that may be used to test the water

Ask HN: Transparent masks for first-responders when responding to an incident?
Should first-responders wear transparent face masks* when responding to an incident?

Humans are visual creatures [1] and read visual cues from facial expressions to assess how to react (e.g. is the other person smiling, frowning, snarling). In tense situations knowing whether the police officer was smiling or snarling can make the world of difference between escalation and de-escalation.

Thinking about it further, transparent face masks would assist people with hearing difficulties to lip read at least some words even if the transparent bit was slightly fogged up.

As with all questions that fall in to the “seems so obvious but not thought of by others that are more knowledgable” category I was curious to throw this out there to see how others felt.

What are your thoughts and opinions on this? Would you feel more reassured by something like this or more freaked out? I would imagine that there are drawbacks including possibly that transparent masks being more difficult to breath through (because of reduced air flow) and probably lots of pros and cons I haven’t considered.

[1] https://www.livescience.com/44494-human-facial-expressions-compound-emotions.html

*I did a quick search and yes, transparent face masks are a thing (most are like a conventional nose and mouth type mask with a plastic cutout around the mouth area)
That’s not the GP’s point. The point is that there are two usable battery duration points: needs charge once a day, and doesn’t need charge for a long time (GP says one week, I believe it would be longer). If there are Android Wear watches that have batteries that last a week or more with comparable usage, then maybe you have a point; otherwise, it doesn’t make a difference.
The TV might still find a way to connect through open WiFi, Comcast xfinity or (a future model) 5G whispernet style connection.

It might not do that today, but perhaps a future firmware update that you would need or want, will do that; Visio TVs started ACRing and uploading that data after an update (they were sued for it and lost; it was called “smart data” or some other innocuous name.
Doesn't really work for Google accounts that have reasonable privacy configuration, in which case it only tells you the email (which you specified), the account ID, the main account name and last profile edit. Of these the main account name might be the real name for many people, but I don't think that's required. The account name is also publicly used by Google in a whole bunch of places (e.g. when you read a Google Docs doc).

It also lists Youtube channels with similar names, which is generally wrong.
Anyone should be able to setup and use Apple TV. (If you trust Apple, that is).

It's mostly because math prevents them from expressing gravity as a quantum field.

The exactly opposite idea of adjusting QM to directly work in geometry of strongly curved space-time is not pursued much. Not sure why. Maybe because it's hard. Maybe because it would just be an extension of business as usual which isn't attractive. Maybe for some other reason.

I can attest to this. In fact, in India, it's considered very stupid and laughable by a very large number of people to buy digital books and music, because they are available for "free" on pirate websites. Read that again: I'm not just saying that people pirate stuff, instead, I'm saying they consider it unimaginable and stupid to spend money because it's available for "free." Ethics never enter the picture, I promise you.

Also, it's considered acceptable and clever to order clothes, use them at an event, and return as "defective." Quaint concepts like morality are not even considered relevant.
The Epic Games Store officially supports both Windows and macOS. It runs on Linux via Lutris, and they even paid them a grant for that purpose. (Of course I'd prefer official Linux support. It seems odd to support Android but not Linux.)

Ask HN: How did you get started in tech and/or Linux?
I’m happy to be able to directly attribute my livelihood to Linux, which is kind of a cool thing to think about.

Would love to hear other anecdotes as to how others got into tech/Linux.

I’m 44 and got my start in 2009, after doing a myriad of other things, like carpentry, aircraft catering, etc.

After an injury, I was basically ruled out of any jobs that required consistent physicality, so I hunkered down and decided to just focus in on Linux full-time (I was already somewhat of a Linux hobbyist, but knew I had a lot of learning to do). After about 6 months of self study, I decided I wanted to work for a webhosting company, and that I really wanted to work in the hosting/server/datacenter/Linux environment. So NOC Technician is basically where it’s at for that sort of thing to get a foot in the door.

I was hanging out in an IRC channel for a local Linux user group, and lo and behold, there was a guy who worked in a local datacenter/hosting company. I got the manager contact from him, and basically called and emailed and bothered the hell out of him until he relented and said OK come work as an unpaid intern. I worked hard, learned and incredible amount there (they hired me on after a few weeks, albeit very cheaply of course)— DNS/network/webserver/troubleshooting, all the fundamentals, and there were incredibly smart and brilliant people there that I learned from. Those were very cool days.

From there I kept learning and have done fairly decently for myself. Good amount of luck on the way probably, sort of right situation/right timing... have worked at two very large ISPs/telecoms in Systems and Server Operations since then.

Wanted to share this maybe to also give encouragement to people just to keep trying and working hard and it can work out. Potentially also a good message in this hard time of the Coronavirus.

Would love to hear some other foot-in-the-door stories.

Would love to see a Svelte SSG (Sapper’s nice but no movement there either).
That's not totally accurate. Alcohols do have smells, but true, for drinks it's probably not the dominant thing you remember.

It's quite obvious how different ethanol versus isopropyl alcohol versus methanol smell (former chemist) when pure.
Not sure what you mean, because Google/Apple also take a cut on in app payments.

This has been part of the standard simptoms list in the UK for a while, I've even heard it described as more reliable than a fever/temperature. The confirmation for it came in part from the work done by kings College London using data from the Covid Symptoms Tracker app, which has had several million users logging how they feel every day since about April. I got a test through them (negative thankfully) when I came down with something and reported it in the app.

Applying “Make Invalid States Unrepresentable”
I agree with you, but I'm not sure we're aware of this problem as a society.

People still think that people making 6 figures are the elite and cheer every time a progressive income tax targeting someone marginally richer than them is introduced by their government.
They are not the enemy, they're not the people lobbying the government so their business can make extra millions or avoid paying taxes with loopholes.

The political discourse always ends up on some hot issue backed by group identity (whether it's minorities, poor people or some other kind of victim).
I don't think the government will ever be able to tackle this conflict of interest and actually impact the ultra rich which maintain politicians.

I just hope we won't get to a violent revolution and physically killing of the rich middle class (kulaks 2.0)
This was my exact presentation of the virus. A deeply profound loss of smell and taste, with an otherwise clear nose. I did develop some significant fatigue and fogginess and a slight cough, but the complete loss of smell and taste was upsetting. The early articles about this connection back in March is what prompted us to get tested. In our cases, though, this symptom appeared almost immediately and stuck with us throughout the infection, so I don't think it's fair to generalize about when anosmia is likely within the course of the virus.
In my part of the world, we don't have counties: all land is incorporated into one commune/comune/Gemeinde or another.
