Element_··on A Tour Inside CloudFlare's Latest Generation Servers
"Specifically, we saw a 50% performance benefit addressing disks directly rather than going through the G3 hardware RAID."

Wow 50%! Is this because raid controller performance hasn't kept up with the evolution from spinning disks to SSD's, or have raid controllers always had that much overhead?

Element_··on Why Canada Has No Big Tech Companies
Not only do you make more as a software developer in the USA, the living costs are much less (I believe the average price of a home in Canada is currently close to double that in the USA [1])

I think a person is more likely to pursue a startup and succeed at it when they can spend less time/energy covering their basic living expenses. A lot of SV giants were started by people in their garages, they simply had enough surplus resources to pursue their ideas[2].

Element_··on Fast Radio Bursts – a new class of astronomical phenomena
omega tau did an interesting podcast on radio telescopes which included a discussion about the specialized hardware radio telescopes use to process the signal data. I think it was on: http://omegataupodcast.net/2009/08/16-radio-astronomy-and-th...
Element_··on Paris Air Show’s Slowest Plane Could Have Biggest Impact
I believe the US air force did extensive studies on this back in the 60's and found that tire ware from spinup only accounted for ~<10% of overall wear on the tires. They found most of the stress comes from the act of braking and turning. Also I believe they found the gyroscopic effects of the spinning wheels actually made it more difficult to land the plane... although that may not be an issue anymore with modern avionics and autopilots.
Element_··on Ask HN: Is it common for founders to doubt their ideas early on?
I found this article very useful for evaluating startup ideas, the author lays out a 12 question strategy. http://www.businessinsider.com/essential-startup-questions-2...

His key point is identifying potential customers and a way to attract them to your product. If you can't identify those 2 things from the start your idea/invention may not be worth pursuing further.

Suporterwall seems like a great tool. How many paying customers out of the 150 active accounts? How many of those are repeat customers?

Just out of curiosity what were you hosting there? How have you found the azure experience overall aside from this latest issue?
Element_··on Mystery Cable Activated in Cuba
"Passive undersea fiber monitoring is well within the means of more than a few intelligence operations"

What kind of equipment/engineering would be required for that?

Has there been any documented cases of a government doing that in the past?

Element_··on Why are the cooling towers on nuclear power plants funny shaped?
That is a pretty crazy way to make a living. Here is a vid showing how they setup the ladders on the side of the chimney. http://www.youtube.com/watch?v=F04dGK1_wYA
Element_··on The Grok prediction engine from Numenta announced
Last year Dr. Davide Maltoni published a paper (Pattern Recognition by Hierarchical Temporal Memory)[1] comparing the algorithms laid out in Dileep Georges original PHD thesis. The results were pretty impressive. There have been many improvements to the algorithm since then too.

Element_··on Megaupload to Sue Universal, Joins Fight Against SOPA
I always wondered who owned the mega label sites and why they were never talked about in the mainstream media. Then your comment led me to the following article: http://news.cnet.com/8301-31001_3-20087753-261/the-mystery-m...
Element_··on Massive networks of stripes appear in Chinese Desert--visible from space
According to the thread on reddit people have posted about these on the internet up to 5 years ago. The most plausible explanation on the thread seems to be that the criss-cross pattern is a test range for autonomous cruise missiles, designed to mimic city streets.

Here is a quote from the thread: "It is an optical test range for autonomous cruise missile targeting systems, to simulate the street grids of cities. If you check the scale of the grid on google earth (+40° 27' 6.89", +93° 44' 20.77") you'll notice that the grid is the size of several city blocks. If you look here (40.479272,93.47713) they have a fake airport painted out over ditches, creeks and inclines. There is also a paved runway short way away, with random bomb craters in it.

The round circle with the 3 jets in the middle is a blasting test range, used to test the dispersion, and effectiveness of explosions over a varying ranges." [1]

Element_··on Ask HN: Dwolla vs Stripe
I could be wrong but I believe Dwolla is a totally new payment system that actually bypasses the credit card system by directly depositing/debiting bank accounts. It designed to replace credit cards and requires the customer to signup for a Dwolla account to pay[1]. Stripe on the other hand is just an API for processing credit cards.

Element_··on Indigo sells Kobo in US$315 million deal
Even if it was a long shot Kobo seemed to be Chapters best/only chance against online book retailers like amazon. As someone who has used the kobo I can say it was a pretty good product, although I am not sure how it would stack up against the new kindle. I wonder what their strategy will be to compete with amazon in the future?
Element_··on HP Names Meg Whitman President and Chief Executive Officer
The article in the NYT today reported that the board fully supported the decisions he had made but didn't like the way he was communicating the changes inside and out of the company. Whether or not that is the real reason they fired him is anyones guess I suppose.
Element_··on Amazon's Jeff Bezos Backs Nuclear Startup General Fusion
I submitted an old article about these guys last year: http://www.popsci.com/scitech/article/2008-12/machine-might-... the article includes a video of their proposed design and an interview.
Element_··on Mysterious US Helicopter Used in Bin Laden Raid
The angles on the tail roter look similar however according to reports the downed helicopter was carrying half of a 25 man seal team so it had to be something bigger if the government was telling the truth.
Element_··on Show HN: Introducing Sendcat: I'm working on a side-project, what do you think?
Looks interesting, I would try to emphasize what makes your service different than other file sharing services (even if its just a simple bullet list). Addi tonally I would get your service to a healthy beta stage before you post a lot of public details or a larger competitor may simply rip off your unique features before you get 100% up and running.
Element_··on Japan suspends work at stricken nuclear plant
World Nuclear News has posted an update regarding recent developments to their site: http://www.world-nuclear-news.org/RS_Second_fire_reported_at...

Sounds like reactor #3 may have suffered damage similar to #2 causing the increase in radiation.

Element_··on Japan suspends work at stricken nuclear plant
I updated the title of the submission, thanks.

Element_··on Oil Spill Fix Idea
Have you ever tried to hold on to a small air filled rubber ball and swim to the bottom of the deep end of a pool? Its impossible. Now think about how that is magnified 1 mile below the ocean. A small amount of buoyant hydrates create a lot of upward pressure.
Element_··on Kurzweil’s Next Book: Creating An Artificial Mind
That's not really true, Hawkins theory revolves around prediction as it relates to intelligence. There is an entire section at the end of the book that explains why intelligent machines based on the neocortical algorithm he proposes won't resemble human intelligence/self awareness for a long time to come (if ever).
Element_··on Fine I'll reveal a past success. It ranked 480 on Alexa at its peak.
Exactly how much money did you make from it? and have you been able to sustain the same kind of returns on other projects since then ?
Element_··on Jason Calacanis at his finest
Yes but for all you know he could have just spent thousands sending him to conferences or some other specialized training only to have him turn around and quit for a competitor. (I have no idea if that's the case but have seen things like that happen at other businesses) Either way it would be nice if hacker news didn't focus on this drama.
