I understand your point of view, but I have a different opinion.

When I see these kinds of claims, my guess is that they are usually based on a failure analysis given a particular replication degree and estimates of failure probabilities of various components and failure domains. Underlying this analysis is usually an assumption about the independence of failures between the failure domains.

The good news is that industry has moved away from the computer as the unit of independent failure to a much larger failure domain: often a cluster within a data center, or an entire data center. This means that the analysis takes into account the infrequent occurrence of a large number of correlated failures within the failure domain.

The bad news is that there are inevitably correlated failures across the failure domains, regardless of how carefully you design to avoid them. Software bugs, coordinated attacks, operator errors, cascading failures caused by well-intentioned but runaway control loops and automated failover mechanisms, and so on, can be the culprit.

So, here's the problem. This statistic from Amazon, if taken at face value, would say that relying on Amazon to keep your data durable and safe is practically risk-free to the point of durability issues never happening in your lifetime (or, alternatively, to such a dramatically small fraction of objects that you might not care).

In practice, however, I suspect you do want to plan for the "unknown unknowns" that will cause data loss at low probability, but much higher probability than 0.000000001%.

Here's another way to look at it: I'd love it if Amazon posted some data about the rate at which they've experienced durability failures in the past year or two, rather than posting what I'm supposing (I might be wrong!) are calculations based on assumptions of dependent failure probabilities.

Thanks eurleif. Latch 27 I've read 3 or 4 articles over the last 12 months about this impact so made the mistake of assuming it was well known. Anyway Google "men shaving less" if you want to see some others. I grabbed the WSJ one because it was first on the list (due to weight of publication credibility) with a great headline! But maybe the article wasn't the best.
Maybe try Lean methodology? Make sure you're clear on the problem you're solving and who you're solving it for. Then come up with a hypothesis and ask specific questions validate or invalidate the hypothesis. https://www.leanstartupmachine.com/validationboard/
Right. unfiltered is a better generic term. Though I should state that it's unbiased from my perspective when I can trust a source.
well, I'm not sure, but since the difference is huge, I'm not sure if routing can cause that significant difference, I'm really not sure about that.
I'm a cofounder at http://hackreactor.com, an immersive school for Javascript engineers. Our grads have your skillset plus a portfolio, and they all get jobs. A few notes:

* The portfolio is key. Here's one from a grad; you can get away with just 2-3 projects: http://tylermcginnis.com/

* I would suggest learning Angular rather than PHP -- learning PHP will put you in a socio-cultural programming context that will lower your career salary and quality of coworker.

* You'll find life way easier if you look for a job in SF.

* Study up on "Cracking the Coding Interview" and make sure that you can code up interview questions.

You may want to just attend my school, which is a structured three-month program to take people like you through the above and more. Average graduate salary is $105,000.
It would be great for my current project. The project is entirely client-side right now, there is 0 server-side component (though certain features in the near future will require a server-side aspect). For what my project is doing, and for the various interpretations of what ZIP can be, having client-side ZIP generation is great.

Just think of all of the container formats that use ZIP with different file extensions. JAR and ePub to be two off the top of my head; I am sure there are plenty more.

The importance is not in compression, it is in container formats.

I never liked these kinds of lists. The people who ask the question always seem to be under- or overwhelmed by the answer (programmers don't need any math?! theoretical computer scientists need all math?!). And the people who answer are almost always skewed toward whatever it is they do.

Even the top-voted response to the OP is obviously biased toward the logic flavor of computer science, with awkwardly scattered recommendations for non-logicish topics that are far more useful for all flavors of computer science ("perhaps even eigenvalues," seriously?!).

These lists even ignore the deeper question being asked: how do you figure out what sort of mathematics you need for the things you're interested in? Not all computer scientists (and programmers) like the same things in computer science and programming. It's much more advisable to figure out what you like before you go around trying to learn all the math there is to learn related to CS, and then ask about what math topics are related to that.
20s with 'average' pressure... good guidance, thanks!
India is witnessing an arguably revolutionary uprising against crony capitalism, their political nexus, unchecked flow of black money & corruption from top to bottom. The elections in the capital (Dec '13) were a strong indicator of what people want as opposed to what media portrays. Social media played a very important role in bringing a party from inception to near majority in almost a year. That was phenomenal. Now the same party is resource stretched to reach out the masses in the biggest election in the world (at country level). The media has blacked out most of the positive news (for obvious reasons). This is where twitter comes in. It's cementing day to day advancements of a revolution across the country. Unfortunately twitter is still limited to a very tiny fraction of the population.
seems like multipart http responses may be pretty close to what we want
This phenomena isn't as novel and modern as the article seems to imply. We see it in technology all the time -- pocket watches and car phones were both seen at one point as signs of wealth and exclusivity, but as they became more affordable that status was lost and other signals take their place. Of course, it seems unlikely that the human race will all of a sudden lose all desire to show off how much more we have than others. We'll just collectively find a new, more exclusive way of expressing it. :) Dr. Suess's book "The Starbelly Sneeches"[0] comes to mind.

I'm writing an iPad app for Mediabrowser 3 (mediabrowser3.com) with another developer. Mediabrowser is in the same space as Plex and XBMC. If everything goes well we plan on launching later this month.

We have invested a lot of time and effort into making the app fast. Our mantra from the very beginning was that speed was going to be a keystone feature for our app. The fluidity of scrolling in our views was one of the main things we focused on. We wrote test code that continuously scrolls our views up and down while we profile it. We are utilizing Path's FastImageCache along with a lot of other caching to get the performance levels that we wanted.

We are considering writing a new backend for our client app so we can launch a similar app for XBMC as well.
This looks pretty cool. I like how it shows potential coworkers.
I use a very fine grind (actually I cheat and use Cafe Bustelo right out of the bag). I've noticed using the inverted method makes the plunge step a lot easier, probably because the grounds are mostly still suspended in the water and not sitting on the filter right away.

Yeah I know that feeling. Thankfully, virtual desktops + 3 monitors has fixed that for the most part, but that's not always usable in some circumstances. I only posted that, as I only found out about it a month ago myself

The other thing I've done (with Zed in particular) is put the icon for the packaged app into my dock, so I can get to it quickly from anywhere. Of course, this becomes unwieldy if you have a lot of them in there!

Well thank you for taking the time to give critique. I was hoping to return to the book at some point and work through the suggested readings in more detail. I will definitely approach it with more caution a second time round and even more so when recommending it to others.

As an aside, how do you know so much about Mr Raymond? :) That's an awful amount of very specific detail.
Hario Slim is a match made in heaven with the Aeropress, as it fits neatly inside the Aeropress's opening to dispense coffee grounds without needing to use the funnel.
I have few issues with this post:

1 - The quality of images are not that good. Some are okay, but overall not that good.

2 - Many microstock sites have large volume of decent looking images and you can always find something decent.

3 - You end-up spending more time on these sites trying to find a decent image than you save money.

4 - Photography (quality) is arts and craft. Because of the higher supply the price have come down but they still need to make money.

5 - Model release? Just looking at one of the sites [1] one of the images had a photo of a skater [2]. I'm not sure if the skater had given a model release or not. But at least with more reputable stock sites you know there is always a model release required.

This is super awesome. That's a great idea and your code (what's in the screenshot at least) looks nice as well.
There was a different approach to this called the "MyTemp system" [1] by a company called "Home Comfort Zones".

Home Comfort Zones has been acquired by a company called "Emme E2MS LLC" [2].

The MyTemp system used pneumatically inflated, vacuum pump deflated "pneumatic damper" devices (balloons, if you will) in the distribution lines. It included plenum sensors for temp and pressure, pumps and hardwired per-room thermostats.

It looked good to me but a system for my home would have cost about $12,000 if I recall correctly (just for the controls added onto an /existing/ system).

With that amount of money, I might have instead have a mini-split variable-rate air conditioning system installed and achieved better savings long term. But both are out of my price range for a retrofit; the target market was very high end.

sxc.hu which recently changed to http://www.freeimages.com/ has a decentish collection. been using it for years when quality isn't too important.

but i tend to use photodune.com for anything a bit more serious, the images vary from $1 to $5, and they have many to choose from. But if they don't have anything good enough then its over to istockphoto.

of course there is also the getty embed thing they announced a while ago (http://www.gettyimages.com/Creative/Frontdoor/embed) which might be handy if you just want small blog content.

Grew up in North Carolina, and I've never seen an electric kettle in anyone's home, ever. The only place I've seen one (besides Target, Wal-mart, etc.) is in the break-room of the building where our local hackerspace is. And sadly, it broke recently, so now we need a new one!

Having been exposed to them now, and even more so after reading this article, I do plan to buy myself an electric kettle though.

FWIW, everyone I know has always heated water in a saucepan or kettle on the stovetop.
As an almost broke student getting a $1k engagement ring for my fiancee (now wife), looking back, it was one of the worst financial decisions we've made.

I don't know of any official revelation but I did get a little insight into the amount of vacation taken at the company I work for when I had taken 'significantly more' vacation than the rest of my coworkers.

The most anyone else took was around the 4 weeks mark. I had taken a little over 6 weeks and that was the upper limit that had my boss telling me I was taking too much vacation. I felt a little shafted by than since my last job was 5 weeks + sick time + bank holidays.

So that's not a lot of information for you but that would confirm your suspicion that it is less. That said it does not translate to unlimited work hours but our work is contract work. We get contracted out to other companies so though we are expected to get the work done and sometimes work >8 hours the expectation is that it will average out to 8hours a day. Be it 4hours one day followed by two 10 hours days or what have you.
fwiw I made a chrome extension to do auto importing from Fito and LoseIt, you basically just set the date-range and if you want to overwrite on TSR's side and it does the rest (Track -> Integrators or Settings->Integrators)

I love the idea, didn't see last week's but I'll join in today.

Currently working on a project known as Senescere, latin for 'to grow old'. Before working in HVAC optimization, for grad school I was a research assistant to a face recognition laboratory that specialized in digitally aging the face based on statistical data such as race/age/gender. Recently, our system was used by Allure magazine to get the opinions of plastic surgery from college-aged women; we're looking to piggy back the exposure with a web app that you can use to see how you age.

Right now, I have a base front-end built up, though we are tweaking to think of better wording.

Front-end Top Portion (Image from PlaceIt by Breezi)- http://imgur.com/50zZgs3

Front-end Second Portion - http://imgur.com/f48NGGF

After an image gets uploaded, we ask to point out the eyes and nose so we can align all 252 'landmark points' to the face through affine transformation. As of right now, I'm in the process of switching where the payment part comes into play. If someone uploads an image, it is added to their dashboard (where I am currently cleaning up).

Once everything is squared away, I'll be looking towards automating our aging process, since it currently is very 'hands on'. If we get enough traction through this, I'd like to branch out from the 'app' area into working with cosmetic companies to build something they can use to show makeup/aging creams without wasting product.

I feel like any data that is being transferred over internet has a real possibility of being surveilled on. Amazon AWS or any other storage provider has to comply with any three letter agency. Calling this secure sound like calling random numbers as random. What do you guys think?
I was surprised, when I finally clicked through after the link stayed on the front page for several hours, to find what looked like a link sharing site. Basically just an ad and nothing more? Why would people unvote an ad?

Yep, I'm all about RSS. I regularly use RSSOwl and/or Digg Reader to consume feeds, and I use a lot of Google Alerts configured as RSS feeds. And one of my company's projects, Neddick[1], is built largely around RSS.

Whenever I watch advanced robotics stuff, particularly humanoid stuff, I'm always struck by feelings that are equal parts awe and mild anxiety.
Going to do my best to put a quick summary (from memory) on something that took us a long time to get right and was a bit convoluted.

Our units actually would report to intermediaries their maximum interaction boundries, which would then be passed to processes to create something somewhat like a mast, someone like a subgrid -- a dynamic interaction zone. All our units had hard constraints (max speed, etc) and worked in global ticks that represented real time. Then, we would talk to global to stretch all the interaction zones to fill empty space and report back boundaries. Then, our units would work in little worlds until they crossed a threshold, we caused a rezoning among them and their neighbors. So initially, the everything would have to be parsed out into interaction zones, but then they could ignore each other for periods of times until a unit strayed across an edge, and then rezoning took place.

Not sure how well it would work with amped up movement (making it have to go all the way up to global more) and not certain how it would work at the scale of 1 undecillion 329 decillion 227 nonillion 995 octillion 784 septillion 915 sextillion 872 quintillion 903 quadrillion 807 trillion 60 billion 280 million 344 thousand 576 points!
Yep. But it's not. The difference is that utilities are especially regulated because they have monopolistic operations. Part of the quid pro quo for going forward with the monopoly is that they have to be open to buying power back from other producers. I don't have the Oklahoma legislation here, but given the available facts, I'm going to bet that's the case. In other words, this taxation isn't a matter of treating residential power generation like any other business, it's about the utility using the legislators to claw back a commitment they now regret making.
It's fairly close to the maximum theoretical rise, if all the ice melted (~80m, apparently)[0]. Also, here are some interesting maps, including Earth with 66m rise, Mars with oceans, and more[1].

I switched to Postman because it supports attaching files to make multipart request, which the RestClient does not.
I like httpie but the app can do a lot more than sending requests now (which you might not be able to do in a CLI tool). You can write tests and run a bunch of requests together to simulate different scenarios: http://www.getpostman.com/docs/jetpacks_writing_tests.

Do you have to compile everything from source, e.g. gcc, glibc, etc? There is no need to get into the whole "reflections on trusting trust" spiel, but I imagine at some point you must rely on your distro? Just use the chromium package from your distro. If not why not build on a desktop/server and copy package to laptop?
I've been reading about these CVD diamonds for 10 years and still haven't heard of anyone actually buying one. It's beginning to remind me of commercial fusion and battery breakthroughs.
Have this, enjoyed it. Cut coffee out as my caffeine deliver device, so I could gift one with a pile of filters.

Very good. You don't get the creme that you get with a French press, but it's still head and shoulders above drip. I had roughly equivalently good quality coffee over a wide range of beans and a fairly moderate range of grinds/grinders from espresso to fine grinds in the cheapy bean/spice grinders you can get at your grocery or walmart/target.

Cleanup and maintenance is better than my drip ever was and the process is quicker, somewhat fun even, and a little bit zen.

> For example, look at the Cuban Missile Crisis. It wasn't even 'proliferation' just the addition of new attack vectors (namely, the much increased potential of a decapitation first strike against the USG) that nearly sent everything ablaze.

Technically the new attack vectors were the installation of dual-key Jupiter IRBMs in Italy and Turkey.

The Soviet shipment of IRBMs to Cuba was a natural response to that poor decision.

The Jupiter missiles were all withdrawn, beginning in January 1963, as agreed with the Soviets.

I'd also propose that the motivation is that some sort of short stack will be all that's available on the tiny embedded processors that are being increasingly built into things. If you want to get under the hood, you're going to have to be able to connect by terminal or serially. Not everything has a screen or keyboard, and this more primitive way of working is a lowest common denominator. It also doesn't hurt that it is a viable approach on bigger hardware and the cloud as well. Back to the Swiss Army Knife analogy.
How does this handle things like static pressure? If you close too many vents it is actually detrimental to your blower fan and cause damage!
