I was 10 when "Ice Ice Baby" came out, and thinking back to that time reminded me of an old memory I haven't recalled for a long time. One time someone played a cassette of To The Extreme from the beginning (I forget the setting; maybe I was hanging out with a friend from school), and I remember hearing an ascending sequence of tones (probably sine waves), each one an octave higher than the previous, before the first song started. Of all the many cassettes I ever listened to as a kid, this might have been one of two or three that ever started this way. Does anyone here know what I'm talking about? What were those tones for, and why did this cassette in particular have them? From what I've read, I gather that this particular cassette might have been a copy made on someone's home tape deck. Or did legitimate commercial copies have those tones too?

It was a tolerant one too. The SGI Pro Video performed better on broadcast grade signals, but would reject many others.

If one wanted to capture vintage / retro computer generated video, the Indy VINO did a great job of it.
I see there are different lenses available for it (wide angle, telephoto etc.) are these photos using any of those? Or would lenses make it even better?

Also what is the output? Can it do 1080p60? Forgive my naivety if I am asking something obvious
I reluctantly but wholly agree with everything polote wrote:

Currently analytics is a fraud, analytics is useless, it is what you do about that data which is important. Most of analytics/ab testing software are just giving data (which is sometimes not even accurate) to customers, so that the people in the analytics team have a job to do. But the reality is that only a very small fraction of those teams know how to use the data to drive more revenue. So if you want to work in analytics there is this HUGE market which today is not addressed by anyone, its how to make more revenue from a website.

I've searched high and low for analytics software that will let me

A) Measure the key things and come up with 80/20 Pateo Principle insights

B) After implementing changes, help measure the impact

Yet all analytics software seems designed to just capture stuff

That's all they do - 'capture stuff'

There are no provisions to leverage that data to actually make more money, or make your product better, or anything of substance
I'm not denying the undeniable fact that some people sometimes want to discover new things. I'm just saying that it's absolutely possible to have it done in a respectful manner. No one, ever, under any circumstances, likes or wants to be manipulated, be it overtly or by having their subconscious played with — period. Adding non-configurable extra anything into people's newsfeeds, be it recommended posts, ads, or "people you may know" blocks, is a crime against user-frendliness. Those who do want to discover new things, will simply open the "discover"/"explore" tab that contains a dedicated recommended content feed on their own. There is no need to nudge anyone to anything.

People aren't stupid if you don't build your UI/UX around the assumption that they are. They also like transparent, understandable algorithms. Chronological feed of (only) the people one follows is as transparent as it gets. A chronological feed with some recommendations mixed in is more opaque and confusing. An algorithmic feed is an epitome of opaqueness. Opaqueness naturally drives users away because it doesn't exactly instill confidence that their posts will reach their followers.

Another example: do you understand what the "see less often" button in Twitter does? No one does. No one likes cryptic algorithmic bullshit forced on them with no way to disable it.

Choice is very important.

> versus what they actually do.

Do manipulations work? Of course they do. Are people happy when they are manipulated? Of course they are not.

> Recommendations aren't advertisements, sites don't make money off them

They absolutely do. Recommendations aren't there because Twitter wants to be helpful — they'd be more user-respecting as I said above if that was the case. They're there because they drive engagement metrics up, and those in turn translate into someone's KPI.
I considered switching from MathJax to KaTeX for my MathJax-based projects such as https://github.com/susam/texme and http://mathb.in/ but I had to decide against doing so because MathJax supports commands like \begin{align}, \begin{equation}, \label, \eqref, \notag, etc. that KaTeX does not, so switching to KaTeX would break many existing documents written using TeXMe or MathBin. I am going to stick with MathJax for now.

Commands supported in MathJax: http://docs.mathjax.org/en/latest/input/tex/macros/

Interesting! I always thought, it would be just logical, that at the center of (at least) a spiral galaxy a black hole must reside, since it looks just like water draining down into the kitchen sink. But for science, obviously, obvious is not enough. It must be proven.

If water access is the bottleneck, you can build storage and reuse it. 1 GWh of hydrogen is equal to 30 tons, or 270 tons of water. That's so small you can literally order a prefab off the internet here in Australia, installed and delivered for $10k.

Extrapolated, that would represent $0.01/kWh in capital costs, or a complete rounding error of costs over the lifetime of the plant. You could even truck it in from a thousand miles away without really impacting the cost very much.

To explore the problem a different way, here in Australia, 8 million megaliters of water was used in farming in the last year. Total energy consumption (not just electricity) in the same period was 1714 TWh.

Storing 3 weeks of our energy needs would require 26,700 megaliters of water be converted to hydrogen, or 0.3% of the amount yearly used in farming, already distributed in regional areas.
> but I didn't particularly try correcting people

If you did try, and they refused, what would that say about them? If they'd rather lose their job than use you by your correct pronoun, what would that say about who they are as a person, and how they're willing to treat others?

> Are pronouns special in some way that other aspects of identity are not?

Special in a way that your skill at CS is not? Absolutely. Much like your name.

> I've certainly been in situations where people with minimal CS skills seeking to solve CS-related problems refused to listen to my proposals or acknowledge my expertise, and this stung

Yeah, I do believe that would sting. Now imagine that it wasn't just someone refusing to listen, but instead the subject of legal battles—the state government of North Carolina legally refused to admit that you're Good At CS. Billionaire authors write essays about the fact that you're Bad At CS. The fact that you are Bad At CS would be the butt of jokes, and shocking news stories designed to make people afraid of you. Those would probably all sting, too.

> More generally, what do other people's beliefs about me have to do with my existence?

Others' beliefs about you? Nothing. Now, if people spend time and energy in an effort to enshrine their beliefs about you into law—say, legally dictating that you're Bad At CS (to continue with your earlier example), then finding a CS job would be pretty difficult. You say that you're Good At CS, but you'd be given no opportunity to demonstrate it, or to counter others' false beliefs about your CS skills.

> What benefit do I gain from being legally married? What part of it do I lose if s/marriage/civil partnership/g is run on the legal code, and I am now in a civil partnership as far as the law is concerned? If I don't lose anything, why should I be miserable?

At this point, I'm not even sure how to talk to you. Are you asking me to explain why people care about the symbol and the institution of marriage? I guess, if you have any married friend or family members, ask them what their marriage means to them.
1. How is this really different to government-mandated microphones and cameras in your house, school, workplace, etc?

2. What’s the endgame here? Open-source encrypted messaging software is widely available. The cat is out of the bag. Every country on Earth could outlaw the technology and it would still be trivially easy for criminals to use it. Do the people behind these proposals not see that?
Whatever happened to that company that advertised IP cameras literally everywhere in the early days of the internet? I think the main one was called the X1 camera.

For those that weren’t around at the time it’s hard to overstate just how over the top ubiquitous that ad campaign was.
The history of water usage, redirection, and decline in the southwestern US is actually pretty interesting. I recommend the book "Cadillac Desert" for a good look and a well-told historical record.
Yup, this is spot on. Not just for demos, but sales in general. It's not about you. It's about the customer and solving problems they care about.

A simulation is only as good as the model it’s based on. So sure, it’s an experiment, but one that’s only valid within the context of the model. Validating the model itself would take a “real” experiment.
This article is good but you can tell it was written by someone who was really young when Vanilla Ice came out. The pushback from the hip hop community was equal parts the lies and the really bad music. He tried to compare Ice to 3rd Base who were respected MCs at the time. Yeah MC Serch is known as a bit of a goofball now but back then he was respected rapper.

Vanilla Ice was making songs like Ninja Rap at the same time classics like Low End Theory, Death Certificate, De La Soul is Dead, Cypress Hill and 2Pacalype Now were coming out. Again, of course he was going to get push back. MC Hammer had the same pushback but not as bad as Vanilla Ice.
Vanilla put on a helluva show last summer at the PNE in Vancouver. He got about 50 girls from the crowd onstage to dance for Ice, Ice Baby. He's a very good showman. Can get the crowd laughing and having a good time
There's no need to make them mandatory, most people already have cameras and microphones in their homes, schools and workplaces that the government can access. This is more about getting access to the social graph.

I sort of disagree that it's commoditised, since the most popular email API would have the moat of being included in every spam filter whitelist. By choosing Sendgrid, paying them for the service and getting their IP ranges you guarantee that you get the greatest chance of getting your email delivered. That commands a premium.

Yeah you can go for Amazon SES or Mailgun or something, but they are used to spam too, Amazon SES to an even greater extent.

You are also guaranteed to get whatever the latest email innovation of email delivery they come up with as one of the early adopters. If they decide to deprecate SMTP and build something more secure, private, easier to authenticate and identify, you get that for "free" without having to change your code.

I see Sendgrid as a relationship maintainer between developer and Gmail/Outlook/Yahoo/long tail of other email providers. You pay them and they make sure your emails show up in those inboxes.

Sendgrid has issues with hacked accounts, which is probably their biggest struggle right now, but even then they have things like reputation. A hacked account would very quickly dip their reputation and be excluded from delivery anyway, without affecting the platform at large. They push 2FA tho, and I think some sort of automatic api key rotation system would be a nice remedy too.

Ultimately, Sendgrid maintains risk on per-account basis. Email providers understand that too, even though SMTP as a protocol and spam filters don't necessarily reflect that. Sendgrid as a platform is never under threat, individual Sendgrid accounts are.
One of my favorite monthly activities is having that two minutes to clean receipts out of my car and wash the front and rear windows.
One of the best book, must read.
Crank your AC15 and play it in the basement, it will destroy your hearing pretty fast without protection. I used to take a homemade 5W amp outside and hear it echo in the woods. Fun times. Quick math—the Vox AC15 has speakers with around 100 dB SPL@1m,1W sensitivity, so if you’re cranked then it’s +24dB, and if you’re 2m away then that’s -12dB, and that’s 112 dB SPL, somewhere around “car horn” or “chainsaw” on the loudness chart. Medical literature puts it at under 1 minute before permanent hearing damage.

It’s not like a stereo where 15W is weak. A 15W guitar amp is pretty damn loud.

If you don’t crank it then I don’t see the point. Or don’t hear it, anyway. I can’t stand the sound of a clean Vox. It’s gotta have some grit.
That makes perfect sense though. Older projects have a ton of baggage that they carry through all of the revisions. New-comers to the space can learn from the mistakes of previous approaches and also utilize the latest and greatest paradigms to solve the problem without worrying about backwards compatibility.
I never hire or have been hired from whiteboard interviews. They seem irrelevant in our situation - we're hiring people to write bug free code that works but is being optimized by someone more senior.

One of my favourite is architectural discussions. Tell them how the app is and ask them how they would do it. Show them a screen we plan to make in the app: How would you implement pull to refresh? What about this complex layout here? What about pop up dialogs? How do you prevent the pop up from crashing the app if a phone call comes in here? How would you suggest caching on this kind of screen? Now assume with have an architecture of X, how would you implement a cache within 4 hours without changing the architecture? Okay, on this page we'd like to take photos and make sure they're not tampered with; you can ask help from the back end to verify but keep the workload to a minimum.

The good answers will propose a solution. The really good answers will offer some solutions and say which don't work and why, and what factors might sway the decision. Acceptable answer is googling and showing the thought process of selecting/rejecting that solution.

I think the only way to really prepare is to get good at making apps, maybe browse subreddits on the topic.
I²C, at least originally (I haven't kept up with all the later variations), so you could put multiple devices on the bus, assuming firmware support.

Linking intelligence and academic performance to genes in the current cultural climate is a bit like suggesting the earth orbits the sun in sixteenth-century Italy. It's not going to end well for you.
Thanks for the great write-up! It's interesting to see how much room there is for personalizing and optimization once you lift the lid on the first change. I started the journey with an ErgoDox and now am typing this on a fully custom hand-wired beast. The great thing about the ErgoDox though is that (a) you can just buy it and (b) it runs QMK and can be programmed through their simple web interface.

For anyone reading this and seeing all the craziness in the post and the linked comments, it's entirely do-able to learn multiple layouts/keyboards and keep them mentally separate. The key thing is to use them both regularly. It doesn't have to be an either-or proposition between "use the standard keyboard of the Earth" and "use this hyper-personalized one". You can in fact use both as long as you don't go cold-turkey and stop using a standard keyboard for six months.
If you compress hydrogen to that pressure and keep it compressed in let’s say a really strong shell, then it will have superconductivity even at room temperature.
Storing larger data sets in CSV format is a recipe for disaster. As tech industry we should really come together With a standard binary format for data exchange. Maybe Arrow?
That's what you consider basic programming?

I was going to make sure they understood loops and maybe classes/methods.

You can ask them data questions without needing to code on the spot.

Which one of us is terrible at coming up with relevant interview questions? The guy who considers tree manipulation basic or the one who considers loops basic?
I have the same problem, with laptop keyboards/etc. I just have a stock of the MS natural keyboards and I sprinkled them everywhere i'm using a computer for anything that isn't typing out a quick email/whatever.

So drop the laptop on the doc, use a natural keyboard. Drop it on the desk at home, plug in a keyboard, etc.

> I've heard is it's breaking up the "pro-Palestinian block" somewhat

If your goal is to screw the Palestinains, this is a good thing. Otherwise, they should have a voice.

> And as for Iran, it's pulling countries away from their sphere of influence.

This is a nonsensical statement: those Sunni countries are already deeply opposed to Shiite Iran even more than they are to Israel.
Government will always be a major threat vector to the population. Encypted communication tools have the effect of creating a wider distribution of power which lessens that threat.

I think the trade-off of denying the establishment some control that would empower it to more effectively combat malevolent behavior by fringe elements, in order to better protect the majority from potential abuses and structural exploitation by the establishment, is worth it.
Let's assume the research is sound. (Inferring from mci's comment, probably not.) But let's suppose we saw this phenomenon in a specific country's population, measured without any sampling bias. It could be from:

- selection pressure for some other trait that happens to involve some genetic material that affects the forearm arteries.

- the recent removal of strong selection pressure for having two arteries, on a trait that generally tends to drift towards three arteries in many directions.

- a dominant gene isolated to one province, which then got diluted across the population when people traveled more.

- a trait found more often in the rural population, which over the past century had more children.
I don’t think that is accurate. Just as with end-to-end encrypted messaging apps, they would have to use targeted 0-day exploits to access the cameras and microphones in people’s homes.

End-to-end encryption doesn’t protect the social graph. They already know who is talking to who; they just don’t know what is being said.
How did the world arrive to this, that we think that NNs solve everything? Beamforming requires zero NNs and works wonderfully (it is all math).
Re: 2, just because other encrypted messaging software is widely available doesn’t mean all criminals will use it. We know this because it happens today — see for example ammo and weapons seized after someone posted about killing federal officers on Discord [1], which isn’t e2e encrypted at all!

This isn’t a defense of backdoors, btw — just saying that we can still expect some criminals to use compromised messaging software even if secure alternatives are easily available.

Book Censorship in the United States
> Paywalls pose a serious problem to discussion sites such as HN where it's hoped (often in vain, but still) that all commenters have read the linked document in its entirety.

Well, do you want to read 20 comments on HN by people who have read the linked document in its entirety, commenting about the linked document, or do you want to read 100 comments on HN whining about Medium.com? Yes, paywalls are annoying, but comments saying "WWAAAAAAHHHH MEDUMB" are not good comments, they aren't interesting reading, they don't add to the dicussion on whatever the linked document is, or on the topic of paywalls. IMO they aren't on-topic here under the guidelines[1] "Don't introduce flamewar topics unless you have something genuinely new to say. Avoid unrelated controversies and generic tangents." (Medium.com having a paywall is unrelated to putting an rPi in a webcam, paywalls are a generic tangent) and "Please don't post shallow dismissals" ("No" is not a thoughtful substantive dismissal) and maybe "please don't complain about website formatting, back-button breakage, and similar annoyances. They're too common to be interesting." - requiring a login is too common an annoyance to be interesting.

In particular to this article and your slatestarcodex link, this webcam article isn't clickbait with zero payoff like the "why are men pointing guns at their dicks" reference, this is a story of something technical that someone did, along with many links relating to the parts they bought, the guides they followed, gif of what it looks like when it's working, links to source code and 3D printer models used. It's not the most technical post ever, but it's incredibly good and relevant to HN compared to a clickbait article on US political social media memes.

I don't enjoy paywalls, and I don't pay for them, but this is what they should be for - if this guy gets a few cents for writing this post about an interesting real project which took a couple of hundred dollars and some decent chunk of hours of design, electronics, hardware assembling and software work to do, then good.

The key word there is “represent”. Radio isn’t sound. If I make a recording and mail it to you, the delivery time isn’t “the speed of sound through the mail”.

You can get into a whole thing about trees falling in forests and how a pressure wave only becomes sound when it’s interpreted as information, but that’s totally irrelevant to an experiment about pressure waves through a medium.
Proving that democracy works. 200 years ago, and in many countries still today, it was 1 person who owned 50% of “lands and titles”. Check out the Queen of England today. She owns... a ton. And she doesn’t do a thing. You may not like Jeff Bezos or Bill Gates but they worked for it and still create things that benefit people.
Quote: "Of course, there was a silver lining to the whole saga. Stonebraker had forked the Ingres codebase in 1982 to create his company. Defeated by the bruising database wars of the 80s, he returned to Berkeley in 1985, and started a post-Ingres database project. Naturally, he named that database post-gres — as in, after Ingres.

And thus PostgreSQL was born."

And 35 years later PostgreSQL is kicking Oracle's butt at every corner.
Yep, after 180 days it only requires a subpoena (which does not require any court). See the Stored Communications Act.

I haven't had one of the "Natural 4000 v1.0" keyboards fail yet. There was a run of them a few years back where the quality sucked though. I had new ones where brand new out of the box one had to mash some of the keys really hard to get them to register.

As someone else said though, they are very susceptible to crap working its way under the membrane since its oddly shaped (and there are a bunch of individual sections IIRC). I've fixed the coffee on the keyboard problem a couple times by opening them up, and very carefully cleaning them (both the contacts and the membrane) with isopropyl and lint free q-tips.
