tracking

I want to write a hit counter script to keep track of hits on images on a website and the originating IPs. Impressions are upwards of hundreds of thousands per day, so the counters will be incremented many times a second. I'm looking for a simple, self-hosted method (php, python scripts, etc.). I was thinking of using MySQL to keep track of this, but I'm guessing there's a more efficient way. What are good methods of keeping counters? A fascinating subject. Incrementing a counter, simple as it may be, just has to be a transaction... meaning, it can lock out the whole DB for longer than makes

My client wanted a way to offer downloads to users, but only after they fill out a registration form (basically name and email). An email is sent to the user with the links for the downloadable content. The links contain a registration hash unique to the package, file, and user, and they actually go to a PHP page that logs each download and pushes the file out by writing it to stdout (along with the appropriate headers. This solution has inherent flaws, but this is how they wanted to do it. It needs to be said that I pushed them hard to 1.) limit the sizes of the downloadable files and 2.)

By using Google Web Fonts can/does Google process the text of the webpage (despite disallowed by robots.txt) track the visitors of the webpage, and (theoretically) recognize them track the changes made to the webpage (despite robots.txt) Except knowing that another download is made to their font and css file, of course. :) I assume Google naturally would/could count and track the number of visitors of my webpage, is this right? edit: "I", "my" - I've tried to use these terms as "generally speaking" here Google can for sure count your users and track their IP address, browser version, and such.

I am trying to track objects with opencv in python from recorded video. I want to give a unique object nr to each visible object when it appears. For example, one object enters the screen and gets nr1, then a second joins the first and gets nr2, then the first object leaves the screen but the second is still visible and still gets object nr2 and not 1 (being the only object). I can't find any information on how to do this online. Any help (including code) is appreciated. The code I have written so far for getting the contours and drawing object numbers: cap = cv2.VideoCapture("video.mov")

This was always a problem for me, as rails doesn't have some mechanisms for session tracking like java frameworks do, what methods do you use to track who is currently logged on your site? I use a simple method by setting up last_visited field with current time every time user clicks somewhere on the site, and then checking for users which have updated that field in (lets say) last 10 minutes. What other methods are there besides this one? If you are using the active_record_store for your sessions, you can try something like this: sessions = CGI::Session::ActiveRecordStore::Session.find(:all,

Anyone who knows how to track iOS app downloads (through web ads) without UDID? I have thought it becomes impossible especially if the user comes from website to AppStore. But a company called WDA seems to make it possible. http://www.lovefortech.com/2011/09/17/developers-track-ads-on-ios-and-android-devices-without-udid-with-apptracker/ http://wda.us/press/track-app-downloads-from-web-ads-without-udid.php I have some ideas but I'm not sure which is the best way. 1) Cookie: iOS apps cannot access the cookie in Safari. 2) Shared Local Strage: Is there any shared storage which can be written by

I run 'git branch -r' and get origin/branch1 origin/branch2 From the man page, the -r option will "list or delete (if used with -d) the remote-tracking branches". So origin/branch1 and origin/branch2 are known as remote-tracking branches. However, you can't commit directly onto a remote-tracking branch (an anonymous branch will be created instead). A remote-tracking branch simply tracks a remote branch when running 'git fetch'. Here's where the semantics get a little blurry for me. If I then git checkout -b branch1 origin/branch1 I get the following output: "Branch branch1 set up to track
