I understand you're poking fun at the common expression used by bitcoin fanboys (or to mock them), but in reality this is neither good nor bad for bitcoin. I personally feel no differently about bitcoin today than I did when I first le

Bitcoin doesn't depend on exchanges any more than your HN karma might depend on exchanges, yet karma still has value in its own sphere - with or without an exchange rate. Anything that can be traded will be traded on a market if th

If we look at bitcoin for what it is (the technology and theory behind it), it hasn't lost any real value. If it did (e.g., if a major flaw were discovered in the technology to render it useless), then people wouldn't still be t

Amazon seems to have truly become the Walmart of e-commerce, and I'm not just talking about what the company does (commerce), but rather what the brand represents. That's not necessarily a bad thing. Walmart and Amazon have prov

Call me unsophisticated, but I personally find it extremely helpful to use a GUI (currently using SourceTree) to interactively review changes before committing. I use the command line for almost everything else, but this is one of those cas

The most interesting point made in the article (for me) is that the presence of noise/grain - which effectively reduces real detail in an individual image - can actually improve the perceived detail across time with high frame rates.

If you're using Rails (or ActiveRecord/ActiveModel specifically), you should probably skip the suggested Ruby example and just use has_secure_password. It's built in, uses bcrypt, and greatly reduces the likelihood of making

Everything you mentioned seems to be accomplished with a simple "git push". When git (or similar VCS) is involved, the push of a new revision of the codebase should (in my opinion) be what triggers a CI build/deploy. As menti

For organizations with more than a handful of engineers, shouldn't deployment happen automatically through something like a CI server? Do we really want every engineer deploying code directly themselves? How do the currently available

I'm not sure I'd call this a Core Data alternative, as it seems closer to a few convenience methods around SQLite. I'd imagine that using this for presenting data in any kind of table view (a typical use for a local data stor

Sounds like stuff that would easily be solved by the market (of course it would be demanded, and of course it would be provided for the right price) if this becomes common practice. No need for legislation. EDIT: Downvote away, but let us r

Wow - I had completely forgotten about Logo. I just now realize that Logo was the first programming language I was ever exposed to, back in elementary (primary) school. If I remember right, we were using an Apple IIGS. Good times!

Running some rough numbers: If a 10mm lens can capture ~120° angle of view, then the image at 1024 px (low quality) represents 0.117° per pixel. In the 30s exposure, there is < 3 px represented by many stars, so that's 0.351° of tol

Sorry, I still don't believe it. Even with a fisheye lens and an incredibly stable aircraft, you're still going to see trails. If you don't believe me, I invite you to try it. EDIT: I assume all the downvoters can provide us
