    For our use even assembly does not "rip Ruby apart.", looking at our 2 most common pages, topic list page and topic page, 30-50% of the time is still spent in SQL. Ruby 2.0 bring decent launch times to Rails (important for dev) due to the fixes falcon committed. Overall, the execution engine itself is pretty sweet and we have incredible visibility into the inner workings with flame graphs http://samsaffron.com/archi…

    > As for GC, it would be nice to have good real time GCs in runtimes. After decades of GC research, I think the conclusion is, "Yeah, that would be nice." Current state of the art gives us some very nice GCs that penalize either throughput or predictability. One of my favorite stories about GC is here: http://samsaffron.com/archive/2011/10/28/in-managed-code-we-...

    Any GC that walks the graph, and isn't mostly concurrent. You will know when the graph becomes complex enough, because thereafter the GC will not let you ignore it. In my experience, as few as several hundred thousand objects can become a problem. Imagine trying to write a responsive 3D modeling app with vertices, edges, and faces all bidirectionally pointing to each other. You the programmer would think very carefu…

    Many months into this experiment I barely get 2 spam comments a month on my blog, I totally respect reCAPTCHA, but demanding JavaScript, doing some minimal tests and perhaps an amount of computation (1 sec on iPad) is the FIRST thing we should be doing http://samsaffron.com/archive/2011/10/04/Spam+bacon+sausage+...

    Try http://m.twitter.com , it's the dressed-down mobile version of Twitter. It doesn't have all the features, but easily makes up for that by the fact that you can actually click around as much as you like without your browser getting all slumpy from loading huge pages or doing javascript. You'd expect caching to help, but there's a lot of truth in the jQuery tax article[1]: even if you got the code cached, executin…

    1. I don't quite understand why people love Rust. I have nothing against it but I just don't quite get why the love . I viewed it as Modern C++ with Memory Management done right from Engineering perspective and elegant syntax with package management done right from the beginning. And may be just my circle or reading list, many Rubyist jumped to Rust, and more often after trying a few times and clicked, they felt in…

    I found http://samsaffron.com/archive/2014/12/01/speeding-up-rails-4... (from the post's comments) interesting. It looks like there were initially quite a few performance regressions in the new release. Adequate Record looks great for rails scaffolds, but (at this stage) doesn't look like it will very useful for production apps that probably have more complex queries. For example, it stops working if your query has…
