hazz··on Man builds 3D printed concrete castle in his own backyard
One advantage might be that you could have all the materials delivered in one go from a single supplier (a concrete manufacturer), instead of having multiple deliveries from different places for the different materials (brick, concrete, cement, rebar, etc).
hazz··on The Lava Lamp Just Won't Quit
>Determined to pursue the idea further, Craven contacted Dunnett’s widow and purchased the man’s patent for a sum of less than £20 (about $30 USD).

This is slightly misleading. If that was the actual price he paid, it was the equivalent of about £500 today.

hazz··on The color of every photo on the internet blended together is orange
This wouldn't explain why the same effect was seen from photos of graffiti (which presumably were outside, in the day.)

"When someone told him that it was probably due to the colors of flesh in photographs, he tried it with a pool of graffiti. Still orange. "

hazz··on “Prison is a bit like copyright”, says jailed Pirate Bay founder
Here is the original article, paragraphs of which seem to have been stitched together to make the TorrentFreak version: http://senficon.eu/2014/08/prison-is-a-bit-like-copyright-pe...
hazz··on Siri’s Inventors Are Building a New AI
From the article: "Google Now has a huge knowledge graph—you can ask questions like ‘Where was Abraham Lincoln born?’ And it can name the city. You can also say, ‘What is the population?’ of a city and it’ll bring up a chart and answer. But you cannot say, ‘What is the population of the city where Abraham Lincoln was born?’”

Out of interest I tried this question on WolframAlpha and it happily returned the answer[0].

hazz··on Just Use Sublime Text
Sublime Text is 6 years old. While not comparable to the age of vim or emacs, it's not exactly a "2 week fad" piece of software.
hazz··on Ageing: The girls who never grow older
Wayback Machine link for people in the UK: http://web.archive.org/web/20140521084936/http://www.bbc.com...
hazz··on Startup School is going global
Any citizen of an EU member state can enter the UK without a visa. Additionally, you don't require a visa if you're a citizen of Andorra, Monaco, San Marino or any of over 50 countries on other continents. It's really pretty open, especially for Europeans.
hazz··on Boy Who Hid in Plane’s Wheel Well Beat Long Odds in Surviving 5 ½-Hour Flight
I don't see how this couldn't be prevented by having ground crew take a quick look inside the wheel wells before the plane taxis to the runway. Is it too elevated to see in easily?
hazz··on Gbatteries (YC W14) Launches BatteryBox, A 50Whr Backup Battery For MacBooks
Battery life was one of the big things that OS X 10.9 touted as an improvement. Apple expended significant engineering effort in reducing energy use to squeeze more out of their current batteries[1]. On the mobile side of things, they developed the M7 co-processor to allow access to sensor data without having to wake up the CPU, and famously never supported flash, both in an apparent attempt to save battery life. They seem to me to be very interested in battery life and I think any technology that could increase it by significant margins would be something they would snap up.
hazz··on Telegram secret chat geolocation leak
This would make sense if cryptography was a young field, but this iteration and improvement has been going on for thousands of years (and modern digital cryptography has been developing for the better half of a century). It is known how to implement cryptography securely. Just as you would expect bridges built today to stay up, and doctors working today to be properly trained, you should expect cryptography implementations to be sensible and secure, or at least not try to carve a new, experimental path when people's lives are potentially at stake.
hazz··on If a Drone Strike Hit an American Wedding We'd Ground Our Fleet
This piqued my interest. The 1993 Chemical Weapons Convention, which outlaws the production, stockpiling and use of chemical weapons, was signed by the United States on the same day it was opened, January 13th 1993 [1]. It came into force in 1997.

hazz··on Don't Distract New Programmers with OOP
In the same vein (linked at the bottom of the article): http://prog21.dadgum.com/156.html
hazz··on So I decided to program a Solar System simulator in WebGL and Javascript
Here's the article describing how the simulator was built: http://lab.la-grange.ca/en/building-jsorrery-a-javascript-we...
hazz··on Ask HN: Who is hiring? (November 2013)
Is it too early to apply for internships over the summer?
hazz··on OS X 10.9 Mavericks: The Ars Technica Review
That's strange - my desktop background wasn't changed by the install. Perhaps you were using a ML-included desktop image that was removed in Mavericks?

After downloading, it took roughly 20 mins to install.

hazz··on Formula E
You're right, my bad. Although I would argue that Singapore and Monaco are in a class of their own in terms of the shape of the track and the subsequent load on the driver and car. Montreal, Melbourne and Valencia don't have the same tight, constricted feel of the other two, because of their wider tracks, longer straights and faster corners. They're also not in areas as densely populated as Monaco and Singapore. Off the top of my head I recall Montreal and Melbourne are both around large parks? Anyway, my original point was that these circuits (in dense urban areas) result in exciting and popular spectator experiences.
hazz··on Formula E
I think choosing street circuits was a great decision. The two street circuits in F1 (Monaco and Singapore) are highly regarded by both the fans and drivers as being exciting and challenging races. On top of this, the possibility of a race running through "your city" has the potential to draw audiences far greater than that of F1.
hazz··on 3-Sweep: Extracting Editable Objects from a Single Photo [video]
This is amazing. My first thought is this could allow F1 teams to get a much better idea of what new packages their competitors are bringing to races early on just by looking at photos and video footage and modelling the new parts.
hazz··on Web Scraping a Javascript Heavy Website: Keeping Things Simple
In many cases websites that load data asynchronously through an API are much nicer to scrape, as the data is already structured for you. You don't have to go through the pain of extracting data from a mess of tables, divs and spans.
hazz··on Hacker sends this through the mail to record a video of the process
In January a similar thing was done in the UK, with the package being sent to Julian Assange in the Ecuadorian Embassy.

hazz··on Tarsnap – Online backups for the truly paranoid
One of the things I love about Tarsnap is the bug bounties, which range from $2000 for being able to decrypt user data right down to $1 for cosmetic issues.
hazz··on How Strong is Your Password?
Why on earth do you need to confirm your password in order to check it?
hazz··on Bruce Eckel on why he's moving back to Windows from Mac
The 2006 era Apple Mighty Mouse had two buttons. It was just designed with a seamless exterior so you couldn't tell from looking at it.
hazz··on Things That Are Never Admitted About Open Source
I agree. I don't necessarily see diversity as a virtue, but more the ability to adapt. When choosing a tool, people will naturally pick the most popular one, provided it suits their needs. Open source allows for everyone to get up and move if a better alternative appears. It may be a 'monoculture' of sorts, but that doesn't have the same consequence as the biological parallel. Open source can adapt.
hazz··on The Google Tax
"Google has also been faced with demands for compensation from content providers such as newspapers, who charge the search giant makes lots of advertising revenue from referencing their material."

"Hollande said “Those who make a profit from the information” produced by media companies should participate in their financing."

It's depressing to see so many examples of the abysmal understanding of the internet that so many politicians seem to have. Ignorance can be forgiven to a certain extent, but not even making an attempt to try to understand the situation - just spending five minutes on google or wikipedia researching the Googlebot will tell you about robots.txt - is inexcusable.

Public and state ignorance of computers and the internet are leading us down a very dark path; there needs to be an effort to try to educate our political representatives, or we risk a future where legislation like SOPA is passed purely out of ignorance of what it means.

hazz··on Parsley.js: never write a single JavaScript line to validate your forms
The url validation seems a bit strict, requiring "http:// at the start. No one types that these days, and I think in practice it might be a real roadblock for less computer literate users. I notice also that "ftp://" is valid, but not other protocols like, say, "afp://" or "git://".

Other than that, great job! I'm actually really looking forward to using this in my next project - form validation is usually such a pain.

hazz··on Meetup, you've been bad, bad hosts
In this case, it seems the service was being paid for:

"We chose to use meetup.com. The status quo was that this is the best platform for event registration and we were happy to pay money (or as a matter of fact, use Ori's alrady paid account) to open up the event's registration using meetup's platform."

hazz··on Is Sugar the Next Tobacco?
I see it more as a manifestation of the fact that things are never as simple as they appear. As we start to look deeper into how our bodies work we're finding that the situation with regards to sugar/salt/fat/gluten/<anything else> is more complex than we realised. These things aren't inherently _bad_, but if we abuse them then we end up with side effects that can be disastrous. The key, as ever, is understanding the effects and treating everything we eat with appropriate respect.
hazz··on Linux is a lemon on the new retina Mac Book Pro
I discovered this about a year ago and it vastly improved my general productivity. Definitely worth knowing. (btw, ` is the button above tab, at least on my macbook).
