Have you seen how quickly an actual house fire takes hold? There are videos of fire department demonstrations on YouTube (http://www.youtube.com/watch?v=rUh4rCjuYDA for example). In sixty (or even ten) seconds of gentle sounds, you'd probably be dead. Not to mention that smoke can take time to rise up to smoke detector level - crucial seconds that you could be using to escape rather than comfortably waking up.

As for the low battery chirp, it should be annoying - that way you attend to it rather than leaving it until later. And chirping only during the daylight hours - how is that helpful if you're out at work? The battery will be dead before you even know about it.

Smoke alarms should be intrusive when they need your attention. That's how they save lives.

P.S. as for the last point - I was actually referring to how difficult it is to work out which smoke detector is chirping. Thus my question - I can't see how it's difficult unless you have lots of smoke alarms. Badly explained on my part, sorry.

This is big news for Node.JS; I'm surprised this hasn't gotten more attention. Hopefully Groupon will follow up with some more technical details of their transition from Rails to Node.JS and how they evolved their SOA architecture.
Private prisons don't make crimes in the sense of making people do things that are widely regarded as immoral, they just seek to make sure things already regarded as immoral become or remain illegal, and seek to have the penalties set as high as possible. That isn't what security companies would need to do to increase demand.

Remember that the costs to security companies of trying to increase crime rates would be born by whoever lobbies to reduce police effectiveness, whereas the benefits would be shared by every security company. Industries form associations to get around these problems, but you can only really do that if you can claim with a straight face that you're acting in the public interest. But while "We need to be tough on crime" and "I'm helping to keep criminals behind bars" are two statements that are easy to publicly resolve "We shouldn't waste so much money on police" and "You should give me money to protect you" make the speaker look like a hypocrite.

I'm sure that security companies lobby in various ways to get legal exemptions to weapons laws, let their employees detain people more easily, etc. Just probably not in ways that would increase crime.

They should still have a battery backup.
Seems like your best bet would be an Intel Chromebook like the Acer C7 - you can easily swap the SSD with bigger one, add RAM and install XFCE/Unity using one of the many options.

It has fans though and you will notice those! And the battery life isn't stellar. But at least it is cheap and relatively light weight and comes with USB ports.
Check out 'The Blank Slate' by Steven Pinker. It presents a fairly thorough accounting of how these sort of conclusions may be reached.
How would you control for this?

The classic way to control for cultural and in-family influences in studies of human behavior genetics is to look for the rare cases of monozygotic ("identical") twins brought up in separate households after adoption. Those studies of monozygotic twins reared apart (MZA twins) set a MAXIMUM figure for the heritability of any trait of interest--because the genes are as similar as they can be between two different human individuals, but the environments, even in separate households, may not be as maximally different as they could be in influence on the trait in question. There is a whole book about the most famous study of identical twins reared apart, which took place at my alma mater while I was an undergraduate and postgraduate student there (in other subjects).

http://www.hup.harvard.edu/catalog.php?isbn=9780674055469

As some people will remember from the press reports at the time, the most culturally variant upbringing two of the separated twins, Oskar and Jack, studied by the Minnesota researchers received was one twin being raised as a Jew, and the other twin being brought up in Nazi Germany and becoming a member of the Hitler Youth.

Exactly. The music industry was never long for this world in the grand scheme of things. If you want to see a real threat to music as an art form, look to the trend we've seen over the decades of local governments trying to put a damper on busking. The good news is that technology will continue to create new ways for musicians to make a living.
The irony is that almost no one will read this.

As a brief addendum... The point of a log scale is to be able to visually compare the relative percent rates of change - last quarter we had 50% growth. This quarter it's less... Dots and lines are useful for this... Not bars.

Is audio even included in DVI? They're probably including it in some non-standard way that differs from other, non-standard ways that other video card manufacturers use to adapt DVI to HDMI with audio.
It's going to be a game of whack-a-mole until the US govt infiltrates enough Tor nodes. Which will happen I think, eventually.
Because the alarms are so annoying, people often end up disabling the alarms and never replacing them. That's dangerous in the long run. In the short run it's dangerous to try to disable an alarm in the middle of the night. I wonder if anyone has ever died from a fall while attempting to stop the chirping in a sleep-deprived state.

I (27, UK) was at a hackathon late last year where there were schoolkids (~17). They were all developing on windows 8 laptops, one of them even had a surface, and they all had brand new nokia Windows Phones.

This initially freaked me out until I realised that they were all learning VB at school (shudder), and were just tooling up to use what they already knew. I was encouraged that one of them had had a look at another language (Perl, of all things) and encouraged him to take a look at Python instead; citing xkcd of course.

Anyway, they were all very excited by touchscreen laptops, and actually using them while trying to do development. It was weird.
Isn't this backwards? Reading the spec (well, the wikipedia page) for DVI, and making some educated guesses, it seems to me the only way to know that a DVi->HDMI adapter is connected is if it provides EDID saying it is an HDMI device.

What is EDID I hear you ask? Well, it's extended display identification data. Physically, it's provided by an EEPROM on the I2C bus of the DVI port at address 0x50.

Could it be as simple as only AMD providing adapters that accurately portray themselves as HDMI devices?

EDIT TO ENTIRELY REVERSE IMPLICATION OF ABOVE QUESTION: No, it sounds like said EEPROM is necessary to make the video part of such an adapter work at all.

It seems AMD additionally identify if it is a blessed adapter and only send audio packets if that is the case. Definitely annoying, but fair given that there is no actual standard. People would definitely moan more if AMD cards blew up non-AMD adapters/monitors connected via non-AMD adapters.
The Nest Protect adds several hardware components that a traditional smoke detector doesn't have, including an ambient light sensor, a distance/motion sensor, a multicolor LED, and WiFi. If your only problem with the current smoke detectors out there is the chirp, then it can be solved by adding just the light sensor and LED, which is not a large cost addition. The additional cost of adding networking hardware, creating a protocol for these to talk to each other as well as the thermostat, and creating a mobile app just to configure the nightlight is what really drives the price so high here.

Hopefully the innovative ideas that they are using for conveying that a battery is low or stopping the alarm from going off when cooking make it into other designs. Quite frankly I don't see the benefit added from networking my smoke detectors.
As a Welshman, it is nice to see these being manufactured in Wales. Shows that we don't have to outsource our manufacturing to the Far East.
I see this as the real value to those with potential CO sources in their houses. You pay out the nose for home insurance all the time and rarely need it. The proposition here is insurance that if another piece of hardware malfunctions and could possibly kill you, these two devices working in tandem can possibly save you or someone else in a home.
Yeah I have been wanting to pick a Chromebook up for exactly the same thing. I can imagine Arch with Awesome being great on one but it seems Google have made it a pain in the ass to get rid of Chrome OS and stick something else on. While I live in my browser I still work in a text editor/IDE and need a terminal with GCC and other bits. Lenovo have some nice portable machines but, like you said about the Sony, they are bulky.

I would love a Chromebook I could easily install a Linux distro on (I don't mind which, I can work within any distro quite happily although I would pick Debian if I had a choice) with a good 13" screen of 1440x900 (IPS). Don't care or want touch. A solid trackpad with multitouch. All the ports on the left (like this HP) as I am right handed an use a mouse to the right mostly so anything plugged in there gets in my way. A 128GB PCIe SSD. 8GB RAM. 8+ hour battery life. CPU I don't really mind but an Intel i3 would be the best (for me) due to compatibility with everything else. Backlit keyboard would be awesome. I am sure they could do all that for $500 or less. Even if I can't take Chrome OS off and have to dual boot that is fine with me as I quite like Chrome OS for a lot of things and only need a real OS for work. If anybody knows of such a machine please let me know!
You should almost always use Percona over vanilla MySQL. Percona is a drop-in replacement with some tactical fixes applied. These are usually OLTP performance related or added visibility. Percona collaborates with quite a bit with the Facebook mysql team which runs an insane amount of mysql servers. As a result of lot of true operational fixes make it into Percona so you don't have to worry about them.

MariaDB is a bit more tricky. I am not sure if they are still considered a drop-in replacement like Percona. MariaDB forked off of MySQL 5.5 and ported over features from mysql 5.6 and the defunct 6.0 branches. They implemented some of those features differently than in MySQL (like GTIDs and some other replication features). If they are still considered a drop in replacement now I don't think they will be able to continue. By forking like they did they are not able to keep up with the improvements and features of the hundred(s) of mysql engineers at Oracle and I expect releases to be slow in coming from them. I was about ready to write them off completely but Google is throwing their weight behind MariaDB due to understandable political reasons so I hope that will save MariaDB. In any result I think MariaDB will diverge farther and farther from MySQL.
> In sixty (or even ten) seconds of gentle sounds, you'd probably be dead.

Which is why I also said that, if the problem gets worse that just a few wisps, the detector should immediately escalate to full alarm.

> And chirping only during the daylight hours - how is that helpful if you're out at work? The battery will be dead before you even know about it.

Again, it can start quiet and polite, and then escalate to more aggressive notifications if you ignore it.

I agree that it is bad to be cruel because it does not gain us anything other than bad karma here. I do not think we should call a fattie as a fattie because it's better to not say anything at all if you can't say anything nice. Of course, ridicule is pretty bad. Some people's problems are visible (physical appearances) while others are not (mental problems), and obviously shaming isn't a good idea.

Btw this isn't a debate/argument but just a casual discussion. I was just observing that how quickly a person pulled an extreme card.
can you do developement without pain on those?
Really? Because mine does that... although it only goes off for like 2 minutes. It's quite handy since mine is poorly located and will activate when there's too much cooking smoke in the kitchen. I'm short so I keep a step-stool under the cupboard, and the alarm is next to the cupboard. Works for me.

To answer your questions: 1) sorta. "mass charge" is just mass. In quantum field theory, particles can have an intrinsic mass parameter. The higgs mass parameter is interesting in that it is imaginary (i.e. its value squared in negative).

2) Not really. In quantum field theory, the fundamental spacetime entity is a field, and quantized excitations of the field are interpreted as particles. So the "Higgs field" is just a postulated field in spacetime, which is associated with the observable particle called the Higgs Boson.

3) No. Roughly speaking, the mathematical mechanism by which the Higgs "gives particles mass" is like this: You write down the theory with the Higgs particle doing its own thing; it turns out this theory can be "viewed" from different perspectives (physicists refer to this as a gauge). If you view the theory from a certain perspective (see: spontaneous symmetry breaking), the algebra of the equation gets all jumbled up. When you untangle the equation by factoring etc, you get back to something that looks like a physics theory, but now the Higgs got mixed into various places in the equation. In some places, it looks just like a "mass charge". This mechanism was originally proposed to get around a nasty problem in physics; our super-awesome theory of electroweak interactions was very clear that the weak bosons (W and Z) must be massless. But when we discovered these particles they were really heavy. The Higgs mechanism is a loophole that allows these bosons to be formally massless in the theory, but which get mixed with the Higgs to give an observable mass as described.

The whole idea of a field having "imaginary mass", and that our universe could be in a spontaneously broken vacuum state (i.e. that we're viewing the theory from a weird perspective) are pretty hard to swallow. This is while the discovery of the Higgs boson is a huge vindication for theoretical physics; it puts all these crazy-sounding ideas on empirical footing.
Consider that it happens regularly every couple of years, especially when you have multiple smoke alarms.

Then if you have high-ceilings it makes it much more difficult (have to go get a ladder in the middle of the night).

It will freak kids out, they're not fun to get back to bed.

The elderly or disabled might not be able to remove the battery or remove the alarm.

I'd say it's definitely a step in the right direction and in-line with Nests other product (probably much of the same hardware).

What's next for Nest? Lighting? Door locks? Security system?
I agree. However, I'd like to see a postmortem of the events and infrastructure in a few months, when everything's hopefully calmed down.
The title is misleading. It isn't hidden. It's called "bad design". It would be nice to put a commit log icon in the sidebar.

The point of the Nest Protect is not that they are selling a fire alarm. It is that they are selling peace of mind. You trust it more, because you interact with it more. It talks to you, you can see it glow green, it lights up when you walk under it. Sure, you can replace all your batteries really easily. But do you KNOW that the alarm is going to work? You never interact with it until your life depends on it. Nest increased your interactions with the device, thereby increasing your trust in it.
This was the original intent of my professor by assigning us this exercise. As a developer, I'm not her typical electrical engineering student though
Old news, it was discovered in 2007 by overclockers.ru user vick:

http://people.overclockers.ru/vick/record9
I have a few friends in pretty successful bands, and most of them (and other artists they know) tend to have a pretty negative view of the 360 deal.

My impression is that it's generally considered to be the only option in most cases. In certain segments of the music industry, major labels are still basically the gatekeepers. Wanna be the next Modest Mouse? Fine. You can put a few records out on a small indie label and do pretty well. Wanna be the next Taylor Swift? You pretty much need a huge label like Universal. The discovery channels for certain types of music are a lot narrower. If you're an aspiring pop singer, you need pop radio. And you won't get it without major label backing.

So the labels have the power to basically say "Here's the deal we're willing to offer. You can take it or leave it". Most artists would probably be better off keeping the majority of their touring profits (since, along with licensing, I think that usually tends to be the biggest source of income) -- but if they're stuck between a bad deal and no deal, a lot of artists will take what they can get.
I've never seen a residential smoke detector that wasn't primarily (and solely) powered by a 9-volt battery. Is hardwired power required for new construction?
I'd like to see a comparative study of how this works for a slender attractive female such as the author v. a fat older man.
You probably have an ionization smoke alarm.

You should replace it with a photoelectric smoke alarm, which is less susceptible to nuisance alarms. In fact, manufacturers are now starting to label them right on the package: "Best for kitchens and baths."
stop this stupid comment.
This is likely among the last prizes we'll see in physics for a long time that has evidence to back it up.

The theory is so far ahead of the practice that things we think we understand just can't be tested in reasonable times. Look at what it took just to get the Boson data.
At first I thought you used "political" to mean opinionated commentary about software development, platforms, and frameworks. And I thought, "bring it on!" And then I realized you meant political. Oh. That.
aka Don Draper's home fire alarm.
I have a box full of shards of smoke detectors that I have ripped off the ceiling and hurled down the stairs because they went off while I was cooking, or making tea, or sneezing nearby. The nest thermostat is fucking stupid, but this smoke detector appears to be a genuine improvement. I would pay twice this price if it works.
It might not be standard, but it's "close enough" that other adapters apparently works once the check is disabled.

But perhaps that wasn't the case when this solution was first implemented and they were just covering their ass in case and nobody have thought to change it.
I can understand buying a Chromebook instead of a Macbook Air, but I see lots of people saying that they have both yet still prefer the Chromebook. What is it that makes a Chromebook so much better than a Macbook that has vastly superior construction, better battery life, and significantly more power?

The Macbook air is small enough to take anywhere, and let me assure you, people will steal anything. Didn't Stallman's ridiculous 200MHZ laptop with a monochrome screen get stolen at an airport or something?

Chrome OS itself can't possibly be that compelling, so does this suggest that people just want a Macbook Air form-factor that runs Linux well?

I don't own either device, I'm just intrigued by the fact that so many people seem to be replacing Macbook Airs with them.
Here's a Defcon talk about more or less that: http://www.youtube.com/watch?v=1M73USsXHdc
That's a very nice illustration.

If you'd like a quick read, here's an "elevator pitch" explaining the Higgs mechanism/boson -- http://dickfeynman.ruhoh.com/physics/higgs-for-laypeople/
I bet there are CYA reasons that current smoke detectors are as annoying as they are.
Smoke detector or not, it is inevitable that there is going to be a fire, and people
will get hurt, and nobody wants to be the maker of a smoke detector that wasn't as
annoying as possible about signaling for battery replacement.

With the nest and the text message, I would worry about the text number/account credentials
getting stale/lost over time, and then when someone gets hurt in a fire there will
be liability shenanigans.
