Our node.js solution uses around 10x less memory than the Netty solution. It also serves many more req. pr. sec on a lot of open connections. Of course, Netty might have improved since we used it and we might have used it wrongly. Generally

Arguments from authority are a fallacy and I am not saying that I trust blindly someone just because they are an expert. I am just stating that domain experts on HN generally have some really insightful comments :)

The thing I love about HN are the comments from domain-experts - e.g. tptacek on security, grellas posts on law or a direct response from a founder/creator. These kind of comments always seem to be very insightful. I don't value general dis

Slightly off-topic: Varnish has some really beautiful C code. It's so good you can get the source code in book form. Check out: http://ing.dk/modules/xphoto/cache/40/31740_460_400.jpg http://phk.freebsd.dk/misc/_book2.pdf ;)

In the recent years the booster for me has been the "Command-T" plugin, which makes it super fast to open files. I can _highly_ recommend this plugin, even if it's a bit harder to install than most other Vim plugins. Check out https://winc

Scaling depends a lot of how much data you got, how much data you generate and how much you plan to grow. Given the size of Basecamp and 37 Signal's future projection I doubt it would be wise to hope that they can scale vertically - - becau

You don't want to scale vertically once you hit millions of users and most other web companies like Google, Facebook, Yahoo and Microsoft have proven that horizontally scaling without big iron is the way to go. Currently the only way to sca

The strategy you usually take with scaling a relational database is sharding, partitioning and de-normalization. And given that Basecamp has millions of users I don't imagine their database structure to be pretty or normalized. This said, i

Instead of making things more simple they have made a lot of things more complex and "configureable". I think Rails 3 is a great example of over-design and over-engineering. I don't really think web-frameworks need to be this complex. If pe

Java isn't really that good fit for real-time web applications as it usually eats a lot memory - especially if you compare it to C/C++ or node.js (V8). A while ago I rewrote a system from Java (that used JBoss Netty) to node.js. The node.j

If you like this you should read "Crossing the Chasm" and "Inside the Tornado" - they go into greater depths of how to find a niche, how to pivot and how the general market forces work.

Developers care about perfomance and if Python 3 becomes faster than Python 2 then I think people will begin to port their stuff to Python 3.

It's a bad call to compare to Desktop Linux. A better comparison is looking at "iOS vs. Android" as "Mac OS vs. Windows" - - The strategy for iOS is very similar to the strategy of Mac OS and the strategy of Android is similar to the strate

The presentation of this framework is quite good, but I don't really like the semantics of Vows - I find them too unnatural and complex, this is probably more rooted against BDD than Vows. What's wrong with testing the old way (e.g. like py

I think you guys have a cool service. I was about to setup nagios+Clickatell for service notifications, but 30 mins into the configs from hell I dropped this idea and started to work on a custom solution. Happy hacking, I am keeping an eye

If it isn't broken, don't fix it and I don't think textual configurations are broken, i.e. you are solving a problem that really isn't a problem. Based on my experience with Flipper (a MySQL master-master tool), SQL configurations are very

I use Fabric (fabfile.org) to automate deployments. It works pretty good and I don't see how it is going to work better with a relational database. Regarding your question: I don't really know or care what version a nginx config is written

nginx does restart, but without taking the site down which is the most important aspect and the most important feature. Brining us to another point, I have deployed a lot of servers that use textual configurations and I can't really see wha

I like how nginx configuration works. It's simple, it's a DSL, it's a text file that's viewable by anyone, you can version it easily, you can comment in it, you can quickly take backups or revert back to old configurations, you can send a k

Before our node.js solution we actually ran Java along with a highly optimized JBoss Netty comet implementation and it had a hard time scaling since it used _a lot_ of memory. Generally, our Java solution used around 10 times more memory th

At Plurk.com we use node.js to provide comet updates to over 300.000 active clients at _once_. It's not a toy and it scales much better than most of other web-stacks I have tried. Read more here: http://amix.dk/blog/post/19490#Plurk-Instan

Their site should be so easy to scale as most of it is static data that can be cached by something like Varnish.
