  • Would popup blockers stop a URL which pops up only when the user clicked on something?

    - by tomeaton
    I'm currently building a web application that can can track a users actions on a particular website and pop a URL if the user takes certain actions, such as: first click, responding to a question by clicking yes / no, clicking a submit button, or exiting the site. It is important that these URLs are served to the user and are not blocked by pop-up blockers. It is my understanding that there are certain exceptions within the major internet browsers that allow pop-ups if they are served based on some user action, rather than serving an unsolicited pop? Is this true? How do I design this web application so that it can serve these pops (and not have them blocked).

  • If I'm running my App Engine app on localhost, will I not see a value for X-AppEngine-Country?

    - by Bartholomew
    According to the Release Notes: All user request have an X-AppEngine-Country header which contains the ISO-3166-1 alpha-2 country code for the user, based on the IP address of the client request. My app is running on localhost with the 1.5.1 Java release which contains the X-AppEngine-Country header but I don't seem to be receiving any value for this header in my requests. Do I have to deploy the app to a production instance to test this feature?

  • Battery life if using GPS and background program

    - by StealthRT
    I was wondering if anyone has created an app that starts in the background and utilizes the GPS to gather the current Lat and Long every minute or so? If you have, would you please provide your battery times? As in, how long does your phone last until its all out of juice from just running that background app with standard cell phone programs. I'm trying to see if it would be worth the time to create an app for myself but if i work for 8 hours and dont have a way of charging my phone during that time then i dont want to be going home and it shut down on me since my app i would create works at my house. I need the app to work since it will see when i am in range of my home (from the GPS) and then send commands to my server at the house from my phone. So thats why it would need to be able to stay in the background doing a check every 1 minute or so. Or only turn on the GPS (Is is doable with iOS? & Android?) whenever its after 5pm each day so that it will minimize the load on the battery?!? Any help or suggestions would be great! Thanks!

  • Is there a method I can override on a JavaScript object to control what is displayed by console.log?

    - by agnoster
    I'm thinking in particular of Chrome, though Firebug would be interesting to. I've tried toString() and valueOf(), but neither of those seem to be used. Interestingly, if I take a function it'll display the function definition - but then if I add a toString() method it will show null! var a = function(){}; console.log(a); // output: function (){} a.toString = function(){ return 'a'; }; console.log(a); // output: null a.valueOf = function(){ return 'v'; }; console.log(a); // output: null Any ideas?

  • Chrome is creating duplicate sessions with the same id

    - by dlwiest
    I encountered an issue while I was revising my session library today, and this might be the first time I've ever seen a browser-specific problem on a back end script. I hope somebody can shed some light. Basically how the session library works is: when instantiated, it checks for a cookie called 'id' (in the form of a uniqid result) on the client machine. If a cookie is found, the script checks that and a hashed copy of the user agent string against entries in a session table. If a matching entry is found, the script resumes the session. If no cookie named 'id' is found, or if no matching entry exists in the sessions table, the script creates both. Fairly standard, I think. Now here's the weird part: in Firefox, everything works as predicted. The user gets one session, which he'll always resume upon connection, as long as 24 hours of inactivity has not elapsed. But when I visit the page in Chrome, even though it looks the same and appears to be executing queries in the same order, I see two entries in the session table. The sessions share an agent string, but the ids are different, and timestamp logs indicate that the ghost session is being created shortly (within a second) after the one created for the user. For debugging purposes, I've been printing queries to the screen as they're executed, and this is an example of what I'm seeing when Chrome should be opening one session and is somehow opening two instead: // Attempting to resume a session SELECT id FROM sessions WHERE id = '4fd24a5cd8df12.62439982' AND agent = '9bcd5c6aac911f8bcd938a9563bc4eca' // No result, so it creates a new one INSERT INTO sessions (id, agent, start, last) VALUES ('4fd24ef0347f26.72354606', '9bcd5c6aac911f8bcd938a9563bc4eca', '1339182832', '1339182832') // Clear old sessions DELETE FROM sessions WHERE last < 1339096432 And here's what I'm seeing in the database afterward: id, agent, start, last 4fd24ef0347f26.72354606, 9bcd5c6aac911f8bcd938a9563bc4eca, 1339182832, 1339182832 4fd24ef0857f94.72251285, 9bcd5c6aac911f8bcd938a9563bc4eca, 1339182833, 1339182833 Am I missing something obvious? The only thing I can think of is that Chrome might be creating a hidden session in the background, possibly to crawl the page. If that's the case though, it could become a problem later, when I begin associating active sessions with entries in the users table. I've been looking for possible bugs in my script, but I haven't found anything so far, and everything works as expected in Firefox.

  • Doing a global count of an object type (like Users), best practice?

    - by user246114
    Hi, I know keeping global counters is frowned upon in app engine. I am interested in getting some stats though, like once every 24 hours. For example, I'd like to count the number of User objects in the system once every 24 hours. So how do we do this? Do we simply keep a set of admin tool functions which do something like: SELECT FROM com.me.project.server.User; and just see what the size of the returned List is? This is kind of a bummer because the datastore would have to deserialize every single User instance to create the returned list, right? I could optimize this possibly by asking for only the keys to be returned, so the whole User object doesn't have to be deserialized. Then again, a global counter for # of users probably would create too much contention, because there probably won't be hundreds of signups a minute for the service I'm creating. How should we go about doing this? Getting my total number of users once a day is probably a pretty typical operation? Thank you

  • App Engine List<String> DB adds chars before string?

    - by Donalds
    Hi, I have a field in my db which is a List. I add strings to that list and it works fine on the development server. This is the result: [mat12, bg10] When I do the same on the deploy server, this is the result: [u'mat12', u'bg10'] I don't understand why it adds "u' '" to the string. I would really appreciate your help. Thanks

  • Why is the page still caching even after the no-cache headers have been sent?

    - by Matthew Grasinger
    I've done a ton of research on this and have asked many people with help and still no success. Here are the details... I'm involved in developing a website that pulls data from various data files, combines them in a temp .csv file, and then is graphed using a popular graphing library: dygraphs. The bulk of the website is written in PHP. The parameters that determine the data that is graphed are stored in the users session, the .csv is named after the users session and available for download, and then the .csv file is written in a script that passes it to the dygraphs object. And we've found, even with the no-cache headers sent: header("Cache-Control: no-cache, must-revalidate"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); Many users experience in the middle of a session, (if enough different graphs are generated) the page displaying an older, static rendering of the page (data they had graphed earlier in the session) as if it were cached and loaded instead of getting a new request. It only gets weirder though: I've checked using developer tools in both Firefox and Chrome and both browsers are receiving the no-cache headers just fine; Even when the problem occurs if you view the page source, the source is the correct content (a table/legend is also dynamically created using php, the source shows the correct table, but what is rendered is older content); the page begins to render correctly until the graph is about to be display, and then shows the older content; the older content displays as if it were a completely static overlay--the cached graph does not have the same dynamic features (roll over data point display, zoom and pan, etc.) And it is as if the correct page were somewhere beneath it (the download button for the csv file moves depending on how large the table is. The older, static page does nothing if you click the download .csv button, but if you can manage to find the one in the page beneath it you can click and still download the .csv. The data in the .csv is correct) It is one of the strangest things I've seen in development thus far. Some other relevant facts are that all the problems I've personally experience occurred while I was using Chrome. Non of these symptoms have been reported by Firefox users. IE users have had the same problems (IE users are forced to use chrome frame). I'm at my wits end at this point. We've sent the php headers; we've tried setting the cache profile for php on IIS as "DisableCache" (or whatever); we've tried sending a random query string to the results page; we've tried all the appropriate meta tags--all with no success.
