Not quite. The essence of a double-spend attack is creating two transactions spending the same bitcoin: one to the merchant (call it A) and one to another of your accounts (call it…

I don't know that comparing EC2 reserved instances to DigitalOcean is really "apples-to-apples", since DigitalOcean has hourly billing and no upfront cost just like EC2 on-demand, …

I think the focus is on pedantic corrections that are entirely irrelevant to the discussion and serve only to make the commenter feel superior. For example, see this recent thread …

A similar method is a "pepper", a form of salt common to all users and stored in the application configuration, allowing the passwords to resist attack even if the hash and user-sp…

Also IcoMoon for generating icon fonts: http://icomoon.io

Well, not dangerous so much as will fail with a "Model instance is not JSON serializable" message. So of course you'll need to construct the list/dictionary representation of your …

> Django does not have a built in JSON HTTP response, so you are going to have to either man up and roll your own (good luck) Am I missing something? What's wrong with: return Http…

Good idea, posted my reply: https://github.com/zmoazeni/csscss/issues/25

It seems like when run on SCSS mode, it expands mixins before running the redundancy check. For instance, two of my selectors both include three of the same mixins, which end up ex…

You may want to mention that the Python library is not thread-safe, since it essentially uses a global variable to store the logged statements until the middleware writes them to t…

It's certainly detectable with precise instruments, but it's not practical to test each and every bit of gold one acquires so thoroughly. Hence the opportunity for counterfeit gold…

Tungsten has a density extremely similar to that of gold (19.25 g/cm³ for tungsten, 19.30 g/cm³ for gold), and is substantially less expensive. And tungsten counterfeiting does hap…

It's used in the sense of "decentralized": no one company controls the Persona system as a whole. Authentication is performed against the domain of the email address the user gives…

Memory corruption is generally defined as occurring when the contents of RAM are modified in a way not intended by the original programmers. [1] Under this definition, buffer overf…

I have a system exactly like this at my company, with a prettier UI on top of the SQL querying. I've been considering open sourcing it for a while; I wonder if there really is a de…

Well, if they crashed on a certain block then the operators of the client would notice and presumably update to a newer version of the client. The problem in this case was more sub…

No. You would have 100% control of the subtree following that failing block, but it would be very quickly outpaced by another subtree that the rest of the network would be working …

Puppet does have a single run mode of usage: http://docs.puppetlabs.com/man/apply.html I use it to manage just 5 servers, with a Fabric script that rsyncs the manifests up to the s…

When run in client-server mode, Puppet will run every 30 minutes by default, overwriting local changes with the configuration on the server.
