  • What exactly is server and client side pagination?

    - by ggfan
    Is server side pagination where the pagination script calculates the number of entries in a database then make the links? All I know is server side is faster and better if there is alot of data and client side is using javascript? What makes a pagination script server or client side? Also, right now I am planning to use this pagination which is like digg-style. Can someone tell me if that is server-side pagination? (sorry if my terminology is off)

  • Access the next button event android

    - by Sephy
    I don't know if it's very clear, but i'm trying to do something when the "next" (bottom right corner of the keyboard) is pressed, and i can't find its keycode. I have tried to look for "next" or "enter" in the keycodes but nothing really relevant... does anyone know? (actually, i've found the enter keycode to be precise, but it does not do anything)

  • iPhone Gps logging inaccurate

    - by Martijn
    I'm logging gps points during a walk. Below it shows the function that the coordinates are saved each 5 seconds. i Did several tests but i cannot get the right accuracy i want. (When testing the sky is clear also tests in google maps shows me that the gps signal is good). here is the code: -(void)viewDidAppear:(BOOL)animated{ if (self.locationManager == nil){ self.locationManager = [[[CLLocationManager alloc] init] autorelease]; locationManager.delegate = self; // only notify under 100 m accuracy locationManager.distanceFilter = 100.0f; locationManager.desiredAccuracy= kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; } } - start logging [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(getData) userInfo:nil repeats:YES]; </code> <code> -(void)getData{ int distance; // re-use location. if ([ [NSString stringWithFormat:@"%1.2f",previousLat] isEqualToString:@"0.00"]){ // if previous location is not available, do nothing distance = 0; }else{ CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:previousLat longitude:previousLong]; CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:latGlobal longitude:longGlobal]; distance = [loc1 getDistanceFrom: loc2]; } // overwrite latGlobal with new variable previousLat = latGlobal; previousLong = longGlobal; // store location and save data to database // this part goes ok } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // track the time to get a new gps result (for gps indicator orb) lastPointTimestamp = [newLocation.timestamp copy]; // test that the horizontal accuracy does not indicate an invalid measurement if (newLocation.horizontalAccuracy < 0) return; // test the age of the location measurement to determine if the measurement is cached // don't rely on cached measurements NSTimeInterval locationAge = -[newLocation.timestamp timeIntervalSinceNow]; if (locationAge > 5.0) return; latGlobal = fabs(newLocation.coordinate.latitude); longGlobal= fabs(newLocation.coordinate.longitude); } I have taken a screenshot of the plot results (the walk takes 30 minutes) and an example of what i'am trying to acomplish: http://www.flickr.com/photos/21258341@N07/4623969014/ i really hope someone can put me in the right direction.

  • Is there a way to keep a selenium session persistent accross multiple tests?

    - by Nick
    I am testing a django application's frontend with selenium and that's first time I use it. I have multiple tests that test things after user logged in. I want them to be separate tests, but I want to have only log in once, is that possible? (As oppose to what I do right now: I log in first, then execute my testing actions of test1, then log in again and execute my testing actions for test2, etc.)

  • recursive_directory_iterator exception

    - by Jon
    I'm writing a simple program which moves files on my desktop to new location. I don't understand why it crashes after the file has been moved. for(recursive_directory_iterator it(desktop), end; it != end; ++it) { if(it->path().leaf() == fileToMove) { rename(*it, newPath); } } A point in the right direction would be appropriated. Thanks!

  • Ocamlrun.lib Not Found For Linking

    - by Onorio Catenacci
    Hi all, Trying to build the OCaml Win32 API binaries for OCaml 3.11.0 on Win 7 and I consistently get a message when I try nmake dynamic: 'cannot open input file "ocamlrun.lib"'. My google skills seem to be failing me--is there something I need to do to get this .lib file? It doesn't seem to be part of the libraries which are included in the OCaml binary distribution for Windows. Can anyone give me a pointer in the right direction?

  • Is there a way to split a widescreen monitor in to two or more virtual monitors?

    - by Mike Thompson
    Like most developers I have grown to love dual monitors. I won't go into all the reasons for their goodness; just take it as a given. However, they are not perfect. You can never seem to line them up "just right". You always end up with the monitors at slight funny angles. And of course the bezel always gets in the way. And this is with identical monitors. The problem is much worse with different monitors -- VMWare's multi monitor feature won't even work with monitors of differnt resolutions. When you use multiple monnitors, one of them becomes your primary monitor of focus. Your focus may flip from one monitor to the other, but at any point in time you are usually focusing on only one monitor. There are exceptions to this (WinDiff, Excel), but this is generally the case. I suggest that having a single large monitor with all the benefits of multiple smaller monitors would be a better solution. Wide screen monitors are fantastic, but it is hard to use all the space efficiently. If you are writing code you are generally working on the left-hand side of the window. If you maximize an editor on a wide-screen monitor the right-hand side of the window will be a sea of white. Programs like WinSplit Revolution will help to organise your windows, but this is really just addressing the symptom, not the problem. Even with WinSplit Revolution, when you maximise a window it will take up the whole screen. You can't lock a window into a specific section of the screen. This is where virtual monitors comes in. What would be really nice is a video driver that sits on top of the existing driver, but allows a single monitor to be virtualised into multiple monitors. Control Panel would see your single physical monitor as two or more virtual monitors. The software could even support a virtual bezel to emphasise what is happening, or you could opt for seamless mode. Programs like WinSplit Revolution and UltraMon would still work. This virtual video driver would allow you to slice & dice your physical monitor into as many virtual monitors as you want. Does anybody know if such software exists? If not, are there any budding Windows display driver guru's out there willing to take up the challenge? I am not after the myriad of virtual desktop/window manager programs that are available. I get frustrated with these programs. They seem good at first but they usually have some strange behaviour and don't work well with other programs (such as WinSplit Revolution). I want the real thing!

  • MongoDB: What's the point of using MapReduce without parallelism?

    - by netvope
    Quoting http://www.mongodb.org/display/DOCS/MapReduce#MapReduce-Parallelism As of right now, MapReduce jobs on a single mongod process are single threaded Without parallelism, what are the benefits of MapReduce compared to simpler or more traditional methods for queries and data aggregation? To avoid confusion: the question is NOT "what are the benefits of document-oriented DB over traditional relational DB"

  • Standalone jQuery or MooTools version of YooTools YOOcarousel

    - by R33BOOT
    I was wondering if anyone knows of a jQuery or MooTools script that will do the exact same thing as YOOcarousel (http://tools.yootheme.com/extensions/yoocarousel). I'm looking to emulate the 'List Styling' setup they have where on the left you have the tabbed navigation and on the right it fades in/out thru each of the tabbed items as they are clicked. Thanks, Ryan

  • Name that blog entry - Modelling changes over time with two db columns only.

    - by disown
    I vaguely remember reading a blog entry (written by a well-known blogger I think) about how to model price changes over time, and that you could model most changes by saving two dates only (two columns in a db). The blog talked about prices on a website changing over time and how you could figure out the right price to charge knowing only when the purchase had been made. Very vague, I know, but my google-fu is failing me, everyone at IRC are busy talking about other stuff and I don't know what to do! :)

  • LaTeX symbol under nabla

    - by anon
    In LaTeX, with \displaystyle , if I do something like: \sum_{i=0} then the i=0 appears under a giant Sigma. This is good. Now, if I do (also in \displaystyle) \nabla_{x} the x does not appear under the nabla. It appears to the lower right. How can I make it appear under the nabla instead?

  • Store data in DB as is, or escaped?

    - by Yegor
    Whats a better way to store textual data, such as comments, user profile fields that require them to type something in, etc? Store the escaped data right away (using htmlspecialchars in php for example), or put it thru the same function before its echoed out?
