For simple ReactJS sitemap integration with React Router, you should check out the react-router-sitemap package. It’s fairly configurable as well, as you can see in the docs, so if you need to include change frequency or things like that, you should be able to do it no problem. Or were you looking for a way … Read more
Ajax polling adds a lot of HTTP overhead since it is constantly establishing and tearing down HTTP connections. As HTML5 Rocks puts it “Server-Sent Events on the other hand, have been designed from the ground up to be efficient.” Server-sent events open a single long-lived HTTP connection. The server then unidirectionally sends data when it … Read more
It’s not AJAX, unless people are using the term improperly. As its name suggests, SSJS is JavaScript that runs on the server, interpreted by a standalone (i.e., browser-independent) JavaScript engine, like SpiderMonkey. Why bother? Well, one area I currently see it underutilized in is in data validation. With SSJS you write one piece of code … Read more
It’s evented asynchronous non-blocking I/O build ontop of V8. So we have all the performance gain of V8 which is the Google JavaScript interpreter. Since the JavaScript performance race hasn’t ended yet, you can expect Google to constantly update performance on V8 (for free). We have non-blocking I/O which is simply the correct way to … Read more
From the PHP Manual: PUT data comes from stdin: $putdatafp = fopen(“php://input”, “r”); Example usage: $putfp = fopen(‘php://input’, ‘r’); $putdata=””; while($data = fread($putfp, 1024)) $putdata .= $data; fclose($putfp);
One really effective way is to submit a token along with the request, and keep a list of used tokens. If the token is not valid, or the token has already been processed, then abort. The token can be as simple as an incrementing integer, stored in a hidden text field, or you can encrypt … Read more

Server side pagination is best for: Large data set Faster initial page load Accessibility for those not running javascript Client side pagination is best for: Small data set Faster subsequent page loads So if you’re paginating for primarily … Read more
In Meteor 0.5.4 this has become a lot easier: First run the following commands from the terminal: npm install -g node-inspector node-inspector & export NODE_OPTIONS=’–debug-brk’ meteor And then open http://localhost:8080 in your browser to view the node-inspector console. Update Since Meteor 1.0 you can just type meteor debug which is essentially a shortcut for the … Read more
This small example uses HtmlAgilityPack, and using XPath selectors to get to the desired elements. protected void Page_Load(object sender, EventArgs e) { string url = “http://www.metacritic.com/game/pc/halo-spartan-assault”; var web = new HtmlAgilityPack.HtmlWeb(); HtmlDocument doc = web.Load(url); string metascore = doc.DocumentNode.SelectNodes(“//*[@id=\”main\”]/div[3]/div/div[2]/div[1]/div[1]/div/div/div[2]/a/span[1]”)[0].InnerText; string userscore = doc.DocumentNode.SelectNodes(“//*[@id=\”main\”]/div[3]/div/div[2]/div[1]/div[2]/div[1]/div/div[2]/a/span[1]”)[0].InnerText; string summary = doc.DocumentNode.SelectNodes(“//*[@id=\”main\”]/div[3]/div/div[2]/div[2]/div[1]/ul/li/span[2]/span/span[1]”)[0].InnerText; } An easy way to obtain the XPath … Read more
HTTP RFC 2396 defines path separator to be single slash. However, unless you’re using some kind of URL rewriting (in which case the rewriting rules may be affected by the number of slashes), the uri maps to a path on disk, but in (most?) modern operating systems (Linux/Unix, Windows), multiple path separators in a row … Read more
