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
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
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
Can you not just loop through the sheets from 0 to Count of names -1? that way you should get them in the correct order. Edit I noticed through the comments that there are a lot of concerns about using the Interop classes to retrieve the sheet names. Therefore here is an example using OLEDB … Read more

Ivo Wetzel’s answer doesn’t seem to be valid in Socket.io 0.9 anymore. In short you must now save the socket.id and use io.sockets.socket(savedSocketId).emit(…) to send messages to it. This is how I got this working in clustered Node.js server: First you need to set Redis store as the store so that messages can go cross … Read more

Note that this can only tell you the browser permitted the cookie to be set, but not for how long. My FF allows … Read more
Client-side validation – I assume you are talking about web pages here – relies on JavaScript. JavaScript powered validation can be turned off in the user’s browser, fail due to a scripting error, or be maliciously circumvented without much effort. Also, the whole process of form submission can be faked. Therefore, there is never a … Read more
