This is really awesome, and sounds like a great thing for people with diabetes (if the accuracy issues are solved).

Further down the line, technologies like this could be a great thing for the rest of us too. We all experience peaks and troughs in our blood glucose and in those troughs we often feel tired, without really knowing why. It would be great to be able to have continuous feedback like "your blood glucose spiked and now is low after you drank that bottle of lemonade an hour ago". Something like this would really help people to make better decisions and would be a great boon for general public health.

Those one frame flashes are easy to see though (which makes me wonder where the previous result of 100ms treshold for image recognition came from). Probably coincidence resulting from similar frame rates, but I think movie projectors were running 72 hz shutter showing each frame 3 times to provide low flicker image. That amounts to 14~ ms per showing which is close to what they tested here. Of course part of the time the shutter is blocking (50%?) so the actual image might be projected only half of the time.
That's a lame excuse for not having a backlit keyboard.

Hacker News Status (HNStatus) on Twitter
I work for a very large company which HN would probably scoff at, plus I work with very uncool things like Java and Oracle.

Don't imagine that HN is some monolithic group of fratboys obsessed with the latest cool whatever. Some of us are dads like you, some of us work for big companies like you (I don't at the moment, but I have no objection to it), and some of us take pride in being able to use the tools we need to use to create useful stuff and don't care about hacker fads, fashion, or fame.
Just an idea: those who have reservations about donating to OpenBSD could just buy a CD-ROM set. You pay for a product part of the cost of which supports the project. And if OpenBSD dies, you can keep it on the shelf and say 'I helped'.

My understanding is that 1000 CD-ROM sets will bring in the CA$20K needed

Lots of interesting work on this by the military. They show rapid-fire photos of satellite imagery to analysts who are looking for interesting features. They monitor the brain activity and look for responses when features appear. Results show that the analysts' brains detect things before they're consciously aware of it.

They then tag the images that registered a response and look at them in more detail. Apparently it's fairly effective.

At my previous university (University of Warsaw) there was an anonymous wiki for opinions on courses and teachers. And it was useful, and people were civil (insults, which were rare, were being removed by community).

So I don't see why anonymous reviews should fail in a similar case.

It's awesome because it's super lightweight and can be installed on virtually any device without even having to run an X ui server.

That also means that you don't have to install anything but this bitcoin client on the system, which dramatically lowers the possibility for attacks.
How do you know SQL and not know what a tree is ?

I was curious about Ivy Lee [1]; some interesting tidbits:

> he was retained by John D. Rockefeller Jr to represent his family and Standard Oil, ("to burnish the family image"), after the coal mining rebellion in Colorado known as the "Ludlow Massacre". Upton Sinclair dubbed him "Poison Ivy" after Lee tried to send bulletins saying those that died were victims of an overturned stove, when in fact they were shot by the Colorado militia.

> Lee espoused a philosophy consistent with what has sometimes been called the "two-way street" approach to public relations, in which PR consists of helping clients listen as well as communicate messages to their publics. In practice, however, Lee often engaged in one-way propagandizing on behalf of clients despised by the public.

> Shortly before his death in 1934, the US Congress had been investigating his work in Nazi Germany on behalf of the controversial company IG Farben.

> Also, you don't want to punish all the publishers just because some (or even if it's a majority) do bad.

Yes, I don't want to punish the honest publishers. But the ugly truth is that I don't really care. My time is limited and I have 1000 other things I'd rather do than fine tuning my block-lists. So I just block them all with the list I subscribe from some guy I never met.

Because it's easy.

Offer a method to block only the bad publishers that is as comfortable (or even more comfortable) as the current ad blockers and you might change something.
That's assuming that the choice is between e.g. one office of size X that 5 people have to share, versus 5 offices each of size X; of course that's going to be expensive, especially in the Bay Area, but it's completely unnecessary. Make it 5 offices each of size X/5, and there shouldn't be a substantial cost overhead.
Some problems with booting directly into Windows (it was eventually included within my autoexec.bat, but not for awhile.)

* Some DOS-based menu programs were really nice. I grew up using X-Tree Gold which had a menu but was also really fast for doing file system operations.

* Some DOS programs wouldn't work well in Windows (programs using serial ports, games), even if you set up PIFs.

* While in Windows, you couldn't use your TSRs (so you'd have to run the programs in non-TSR mode and set up different hotkeys for them and get used to the changes.)
IMHO, the FM-index deserves to be highlighted. That it is possible to store a string in a compressed format which can answer length-P substring queries in O(P) time (with good constant factors) is quite surprising at first sight.

Not only that but SO in general is a rather bad source for programming advice - at least for beginners.

What you generally see on SO happening:

- Statements are being marked as "correct" even though they did not answer the question. It happens all the time that people as a Cocoa/OS X related question and get a iOS/UIKit answer which is then marked as correct.
- Wrong answers are marked as correct all the time.
- There are a couple of people who reformat my answers on SO all the time. They add emphasis, reformat my code/paragraphs etc. I don't know why they are doing it - probably to get a couple of points easily. This is so annoying.
- It seems to me that collective intelligence sometimes does not produce the best answers... My friend and myself often begin our days by telling us about funny "answers" on SO, how we tried to argue but then got "overruled" by the majority even though the majority is wrong.

This is probably not the right place to rant about SO...
Depends on a large number of things. As an advertiser you can pay based on location on the site (e.g. the advertiser will pay more for a banner than a little side unit below the fold).

Some adverts are pay per view, pay per click, some are commission based (referrer gets a cut). Sometimes it'll be a few dollars for a few thousand views, other times it'll be a few hundred dollars for a week's visibility.

For click throughs, fractions of a cent to a few cents I guess. Commission is obviously worth a lot more (a few percent of the purchase price typically), but harder to convert users.

Have a look at buysellads to get an idea of how this works. Unsurprisingly Adblock has a field day if you try and view the website with it turned on ;)

There's nothing wrong with keyboard innovation, the problem is with commodity laptop manufacturers trying to innovate in an integrated device. The important differentiators on laptop are numerous: form-factor, specs, screen, etc. Even keyboard quality is a big factor, so trying to get clever with the layout and soft keys is just begging to throw a deal breaker in.

What laptop manufacturers should be doing is following Apple's lead and standardizing heavily across their entire line and keeping that reasonably in line with national keyboard standards.

Leave the layout innovation to external keyboard manufacturers where there is an opportunity to make drastic changes and sell them based on the strength of that innovation alone. Later the best of the innovations can trickle their way back into laptops.

I am rather sure that malicious use of TV broadcasting would be cause for FCC to withdraw the broadcasting license for the company.

What you're saying is utterly incorrect, speaking as a GNOME release team member. Pretty poor to first complain about moving goalposts, yet at the same time misrepresent what was done.

In the beginning of 2012 (Jan/Feb) I highlighted the various problems. Nobody stood up to help out. Now it is 2014 and we do NOT rely on systemd.

Further, we DO rely on dbus APIs and can rely on ConsoleKit still.

Get your facts straight please.
> The tax-payers have subsidized massive broadband expansion that never happened. Many of the players pocketed the savings and just never followed up with their end of that deal.

All I can say is that subsidies -believe it or not- do not exempt anyone from mathematics. If you are unable to see that packets travel more than one "freeway" there is nothing to say at all.

Hell, even freeways don't work like that. Believe it or not, cars on a freeway come from somewhere and go somewhere. This affects the capacity of the freeway for obvious reasons. If people did on freeways what they do with p2p, random any-to-any travelling, there would be no possible way to keep freeways uncongested, and yet there'd be loads and loads of "free" space. And yes, we would all be talking about making more intense users pay more, or get them off the roads alltogether. Hell, we're doing that now.
And it's nevertheless the best argument we have. You see, capitalism would suggest the price of any product goes down to the marginal cost. That means the price paid for labour should be just barely above subsistence.

Do you want to live like that ? If the answer is no, you must find a way to avoid it, and not being an "open borders weirdo" is one of the more common suggestions.
And as someone who wants to read his content, him not making money is your problem too. Maybe the benefit of blocking adverts out-weighs the downside of denying the content creator revenue, and that's a fine choice to make. But don't pretend any of these issues are one-way only.
That's because people like to equate wanting their desk to be neat with OCD.

I'd buy an HH keyboard in a heartbeat if it had the same layout as the Microsoft Natural keyboards. No, I lied. I would buy four or five; for home, for work, and for spares.

I use a Kinesis split keyboard now, and it's pretty good, but ESC / F1 are in the wrong place and I had to remap them.

(MS has been serially fucking up the Natural keyboards for nearly a decade now. The 4000 series started the decline, and I can't use the damned things at all now).
Amazon plans to ship your packages before you even buy them
What happened with GNOME is accurately described by myself in:

http://blogs.gnome.org/ovitters/2013/10/10/wayland-vs-usrsha...

http://blogs.gnome.org/ovitters/2013/09/25/gnome-and-loginds...

I'm a GNOME release team member. We get really nice contributions from OpenBSD. But 100% of the development is done by people working on Linux. It has been that way since at least 5+ years.

This "portability" complaints is IMO empty talk: actually contribute and make things happen. However, at the moment systemd will share various things across distributions and desktop environments, allowing GNOME developers to not need to maintain as much code as we do (e.g. the freedesktop.org ConsoleKit).

I'm guessing people won't read the blogposts, but oh well :P
Exactly. I haven't intentionally used capslock in 20 years.
Why we are not afraid of Microsoft
Interesting, but also pretty scary. It's effectively machine learning with real people as the algorithm. Literally plugging people into a computer.
Games. This is really, really bad for games.

Also, I tend to fiddle with keys, tapping shift nervously. Having this result in capslock would drive me nuts. It would be a deal-breaker if this functionality were in the keyboard firmware and not configurable.
Can't wait to be there !
Why turn things around? Systemd makes Linux specific features available. Nobody ever complained about FreeBSD having jails. Yet there are complaints that Linux has Linux-only features.

So by using your FreeBSD jail example: Because there aren't any complaints regarding jails, systemd should not be complained about.
It's too infrequently used and increases the distance between keyboard and mouse.

That's why I just switched to using the mouse with my left hand, even though I am right handed.
Since we're bashing on laptop keyboards, I hate with passion all the layouts that put FN key in the bottom left corner instead of CTRL. It's far easier to reach the button in the very corner and I use CTRL order of magnitude more often than FN.

Also it seems that for each producer, half of the laptops have FN and the other half have CTRL in the corner which just adds confusion when you're using someone else's machine.

Can someone persuade me to the superiority of FN-in-the corner?
OS X on OS X
The complexity is there, you just don't see it. Systemd handles all types of services. Sysvinit does not. Systemd abstracts a lot, making it easier per service (by putting more in systemd). In sysvinit a lot is copy/pasted across services. IMO making everything more error prone.

I'm not the original complainer about UTF8 support, but "If you want to store it as unicode text feel free to use the ntext and nvarchar types." comes at a price: for the o so common almost-ASCII text collections, it blows up your disk usage and I/O bandwidth for actual data by a factor of almost 2. For shortish fields, the difference probably isn't that, but if you store, say, web pages or blog posts, it can add up.
> If Σa_i is conditionally convergent then there are an infinite number of both positive and negative a_i.

That's true, but that's not enough for your proof -- e.g. \sum (-1)^n/n^2 also has infinitely many positive and negative terms, but converges absolutely.

What you need is that sum of all elements in at least one of A_+, A_- (thus also the sum of all elements in the second one) diverges (the order you take the sum in doesn't matter here, as you surely know).
You have definitely not been thinking too much about that one.

Isn't it a kind of self-fulfilling prophecy? As in, Amazon make a loose prediction about what you'll want to buy, but the hook of having that one available within 1 hour biases you to be more likely to buy that item. Then Amazon get to say "we're amazing at prediction!" whereas they're actually amazing at altering customer behaviour. Which isn't to say that that's a bad thing, it's just a bias which needs awareness.
> Does anyone know the actual value of a single ad impression?

This is often summarized as RPM (revenue per mille) or eRPM (effective RPM), i.e. how much income a site's ads bring in per 1000 page impressions, regardless of how it's paid out (per-click, per-view, per affiliate purchase, etc.). And that varies hugely between sites, anywhere from below $1 to above $100. A typical case is around $5-10 for many publishers, I believe. So that's about 0.5-1.0¢ per page view.
Systemd provides various things that desktop environments want to use. This is not limited to GNOME. I talked to Enlightment and they're going to make more use of various bits (e.g. user session). Similar with KDE.

Dismissing it entirely like you're doing and pretending this is about forcing: good luck with that. Just like distributions were forced to use it right? Not merit, just pushed?

Try coming up with something concrete. Until that the lack of specifics in your posts tells me enough.
My wife grew up practically across the street from that house and the way it was discussed in the neighborhood was that it is/was a CIA safe house. A utility station seems much more plausible.
It's because in the US, ADD/OCD-like behaviors are seen as a problem, while in Europe they're considered "natural" up to a pretty high point.

I don't even know which is worse - making kids with slight ADHD take stimulants (US) or ignoring the symptoms unless they're truly a problem (bad grades and behavior aren't - you're just mentally stupid or a culturally uneducated prick in Europe).

People with slight ADD/OCD can get by, but they'll always feel something is wrong and that no one understands them (plus some may never reach their full potential), while those on meds will suffer later on...
As the article states, not because yuppies, because church and general environmental sensitivity on the part of the city management. They planned to disguise it forty years ago when it was planned, as I'm sure many communities have similarly done. Imho, this is similar to the practice of disguising urban cellular towers, a la http://twistedsifter.com/2012/08/examples-of-cell-phone-towe...
Those init.d scripts are different per distribution. With systemd the same thing is provided in a configuration file. Much simpler, clearer and understandable. Further, "service $FOO status" actually shows you stderr+stdout output, making it easy to debug (in case of failure).
It's a problem of tracking the payments and keeping track of everything at that point.

If it's 2 dollars a month for 10 or so sites that isn't that much money but setting up 10 different credit card automatic payments is a pain in the ass. Then I lose a card and everything breaks.

If we had a nice model to aggregate articles on one central site with profit sharing from subscriptions then it might be better.

One of the prerequisites is to smacktack the ol' Microsoft 'legacy' and then whistle dixie.
I didn't watch the numberphile video and just read this.

Can someone explain to me why I am allowed to add a padding zero at the start without taking it out at the end?

By adding it, I am giving the sum an offset, and I can kind of understand why adding zero is not a big deal, but they reasoned:

Then S1 + S1 = (1 - 1 + 1 - 1 ...) + (1 - 1 + 1 - 1 ...)

= (1 - 1 + 1 - 1 ...) +
(0 + 1 - 1 + 1 - 1 ...)

= (1 + 0) + (1 - 1) + (1 - 1) ....

= 1 + 0 + 0 ... = 1

But I might as well leave the leading Zero out and argue that:

Then S1 + S1 = (1 - 1 + 1 - 1 ...) + (1 - 1 + 1 - 1 ...)

= (1 - 1 + 1 - 1 ...) +
(1 - 1 + 1 - 1 ...)

= (1 + 1) + ( -1 - 1) + (1 + 1) ....

= (2 - 2) + (2 - 2) + (2 - 2)... = 0
