sylvinus··on Why we moved from NodeJS to Ruby on Rails
It must not be that silly because 10gen hired the author of Mongoose ;-)
sylvinus··on 10 Python One-liners To Impress Your Friends
I find it weird that the author writes about one-liners in python without knowing about list comprehensions
sylvinus··on Live: SpaceX Dragon docking with ISS
Watching the Dragon approach from the point of view of the ISS is incredibly exciting in itself, but almost unbelievable when you think about the speeds they are flying at relative to the ground!

The question now is what will be the response of the leaders of the community fork Mageia? http://www.mageia.org/en/
sylvinus··on Why we moved from NodeJS to Ruby on Rails
MongoDB has good drivers for Node (as for most other languages) but also a fully-featured ORM that can save time in these kind of projects: mongoosejs.com

MongoDB also ships with a JS runtime so you can run map/reduce calls written in JavaScript entirely DB-side, as well as other goodies.

So it's fair to say that the language that makes the most sense when using MongoDB is JavaScript, even if that wouldn't be enough IMHO to justify using Node for a project.

sylvinus··on The trouble with Javascript
... and your point is?

I wonder how they plan to recoup royalty losses from this? Is this just a marketing investment?
sylvinus··on PHP: A fractal of bad design
> Where's the Ruby version of this? The Python version? The JavaScript version?

heroku ? you don't even have to upload anything manually, a single command deploys your app.

sylvinus··on Joyent deprecates no.de and partners with Nodejitsu
Text from the email just sent to no.de customers:

Greetings!

We are emailing you with some great news. Joyent Cloud is partnering with Nodejitsu to provide a new Node.js development environment that improves on Joyent’s existing no.de service. You can sign up for the new service by clicking here.

Below is an FAQ explaining what this partnership means. Thanks for reading!

Q: Can you explain the Joyent Cloud / Nodejitsu partnership? What does this mean?

A: Joyent Cloud and Nodejitsu are partnering to deliver a Node.js development environment that will leverage the development and management tools of Nodejitsu and the Joyent Cloud infrastructure to deliver high-performance Node.js applications. Nodejitsu will run a significant part of its infrastructure on the Joyent Cloud. This will provide a superior continuum for Node.js apps spanning development, test and production phases of an application life cycle.

Q: I have an no.de account. How does this new arrangement affect me?

A: The new arrangement does not affect you whatsoever. You can still use your existing no.de account as outlined under the Terms of Service of the free program. While we think those who check out the new Nodejitsu development environment will want to switch over from no.de immediately, we do not have plans to make changes to the no.de service at this time.

Q: I want an no.de account but couldn't get one before because the system was over capacity. Can I get one now?

A: You won't be able to get a no.de account, but developers wishing to access a full-featured Node.js development sandbox should sign up for the new Nodejitsu / Joyent service.

Q: How do I move from the no.de environment to the Nodjitsu environment?

A: All Node.js code deployed in no.de should run equally well in the new Nodejitsu sandbox. If users are on no.de v2, the only significant changes are the switch from “git push” to “jitsu deploy”, Nodejitsu’s deployment tool. Jitsu deploy will walk you through all necessary changes configuration changes. For more information on how to use jitsu deploy, click here.

Best Regards, The Joyent Team

sylvinus··on How I built a Hacker News mobile web app, Part 2
"As long as there's no way for me to simulate a built-in browser in a web app, HNmobile will remain being a non-standalone app."

I'm not sure if you had a look at it yet but there is a PhoneGap/Cordova plugin called ChildBrowser that may do what you want here. I can help you getting setup with a PhoneGap project for your app if you want!

"Since it's hosted on another domain, the API supports CORS so that HNmobile can do cross-domain XMLHttpRequests."

Why don't you use JSONP?

sylvinus··on Apple Has Started Rejecting Apps That Access UDIDs Amid Privacy Concerns
I'm not 100% sure they already do, but will Apple continue using UDIDs in iAds? Because if they do that would grant them an incredible competitive advantage against all other ad networks...
sylvinus··on "BitC isn't going to work in its current form"
Thanks, the headline made me think it was actually about BitCoin ;-)

The animation of the left sidebar on each page is really annoying.

Aside from that, it looks really clean!

sylvinus··on I created IdeaWave as I couldn't afford TED ($7k) or IdeaCity ($3k).
TED doesn't charge and doesn't pay speakers. Same for all TEDx events. IMHO it's a large part of what sets them apart from other conferences.
sylvinus··on Anonymous plans to take down the 13 root DNS servers that power the Internet?
Most interesting bit :

The principle is simple; a flaw that uses forged UDP packets is to be used to trigger a rush of DNS queries all redirected and reflected to those 13 IPs. The flaw is as follow; since the UDP protocol allows it, we can change the source IP of the sender to our target, thus spoofing the source of the DNS query.

The DNS server will then respond to that query by sending the answer to the spoofed IP. Since the answer is always bigger than the query, the DNS answers will then flood the target ip. It is called an amplified because we can use small packets to generate large traffic. It is called reflective because we will not send the queries to the root name servers, instead, we will use a list of known vulnerable DNS servers which will attack the root servers for us.

Note that $250m just seems to be the quarterly fee...
sylvinus··on Kill Hollywood? Let's fix politics instead: kill lobbying.
I'm not expert on the subject but one should also consider how it goes into countries like France where lobbying is already illegal, but still happening in other ways or channels.

Actually much, much less than $180: that includes the cost of all the parts, many of which are not produced in China.
