  • Is there a Google 3d Warehouse API?

    - by Jayesh
    Does anyone know if there is an official or unofficial API for Google 3D warehouse. I know of the iPhone app NaviCAD, which shows Collada models from Google Warehouse - it has search, most-viewed, most-recent functionality; so I guess it is using some sort of API to get that data. But I couldn't find any auch api after searching around. Do you know if there is any?

  • Cocoa - array not sorting?

    - by Mike
    I have this set NSMutableSet *mySet = [NSMutableSet setWithObjects: @"2", @"8", @"7", @"0", @"3", nil]; I copy the set to an array and sort it using NSArray *sortedArray = [[mySet allObjects] sortedArrayUsingSelector:@selector(compare:)]; The resulting array is in exactly the same order as the set and is not being sorted. Why? thanks for any help. EDIT: CORRECING A TYPO.

  • Mysql ninja tricks

    - by alexn
    Hi, what are your mysql ninja tricks? What features are extra special? I'm starting with ORDER BY FIELD which enables you to sort in a particular order, like this: SELECT url FROM customer ORDER BY FIELD(customer.priority, 1, 2, 3, 0) Features like this is hard to find in the mysql documentation. Bring it!

  • High-concurrency counters without sharding

    - by dound
    This question concerns two implementations of counters which are intended to scale without sharding (with a tradeoff that they might under-count in some situations): http://appengine-cookbook.appspot.com/recipe/high-concurrency-counters-without-sharding/ (the code in the comments) http://blog.notdot.net/2010/04/High-concurrency-counters-without-sharding My questions: With respect to #1: Running memcache.decr() in a deferred, transactional task seems like overkill. If memcache.decr() is done outside the transaction, I think the worst-case is the transaction fails and we miss counting whatever we decremented. Am I overlooking some other problem that could occur by doing this? What are the significiant tradeoffs between the two implementations? Here are the tradeoffs I see: #2 does not require datastore transactions. To get the counter's value, #2 requires a datastore fetch while with #1 typically only needs to do a memcache.get() and memcache.add(). When incrementing a counter, both call memcache.incr(). Periodically, #2 adds a task to the task queue while #1 transactionally performs a datastore get and put. #1 also always performs memcache.add() (to test whether it is time to persist the counter to the datastore). Conclusions (without actually running any performance tests): #1 should typically be faster at retrieving a counter (#1 memcache vs #2 datastore). Though #1 has to perform an extra memcache.add() too. However, #2 should be faster when updating counters (#1 datastore get+put vs #2 enqueue a task). On the other hand, with #1 you have to be a bit more careful with the update interval since the task queue quota is almost 100x smaller than either the datastore or memcahce APIs.

  • Is there a Grid plugin for jQuery that has similiar capabilities to the Ext-JS Grid?

    - by Ehrann Mehdan
    One of the most appealing features of Ext-JS is the Grid control in my opinion. I was searching for something free that does something close and have set my hopes on jQuery. I haven't found a jQuery (or other LGPL compatible) Table / Grid plugin that allows to: Reorder columns by dragging Resize columns by dragging Add or Remove columns on the fly Have a default good looking UI (subjective, but Ext-JS look I think is a concensus) In addition to the rest most grid controls have (Sort, Paging etc) Is there a free (LGPL) jQuery plugin that does the above?

  • Web Services API Versioning

    - by Paul Izzy
    I offer a small Web Services API to my clients which I plan to evolve over time. So I need some sort of versioning, but I can't find any information about how you do something like that. Is there a best practise? How can I keep adding new functionality without breaking compatibility with the web services consumers?

  • Table Partitioning

    - by Ankur Gahlot
    How advantageous is it to use partitioning of tables as compared to normal approach ? Is there a sort of sample case or detailed comparative analysis that could statistically ( i know this is too strong a word, but it would really help if it is illustrated by some numbers ) emphasize on the utility of the process. Thanks, Ankur

  • git clone fails with "index-pack" failed?

    - by gct
    So I created a remote repo that's not bare (because I need redmine to be able to read it), and it's set to be shared with the group (so git init --shared=group). I was able to push to the remote repo and now I'm trying to clone it. If I clone it over the net I get this: remote: Counting objects: 4648, done. remote: Compressing objects: 100% (2837/2837), done. error: git-upload-pack: git-pack-objects died with error.B/s fatal: git-upload-pack: aborting due to possible repository corruption on the remote side. remote: aborting due to possible repository corruption on the remote side. fatal: early EOF fatal: index-pack failed I'm able to clone it locally without a problem, and I ran "git fsck", which only reports some dangling trees/blobs, which I understand aren't a problem. What could be causing this? I'm still able to pull from it, just not clone. I should note the remote git version is 1.5.6.5 while local is 1.6.0.4 I tried cloning my local copy of the repo, stripping out the .git folder and pushing to a new repo, then cloning the new repo and I get the same error, which leads me to believe it may be a file in the repo that's causing git-upload-pack to fail... Edit: I have a number of windows binaries in the repo, because I just built the python modules and then stuck them in there so everyone else didn't have to build them as well. If I remove the windows binaries and push to a new repo, I can clone again, perhaps that gives a clue. Trying to narrow down exactly what file is causing the problem now.

  • Automated regression tests for java applets?

    - by Roy Tang
    We're working on a project with a number of applets that has to work across a large range of OS (WIndows, Mac, Linux), browsers (IE, FF, Safari, etc) and Java versions (1.5+), and it often happens that a fix we apply will cause some sort of security exception an another platform or some other error. Is there any way for us to prepare automated tests to immediately catch those problems in different platforms? I think it's not necessary to check that the gui parts are appearing as intended, but just to detect whether unexpected exceptions are occuring.

  • .NET XBox Live Account API

    Is there a .NET API available to get data from your XBox Live account? All I'm really interested in is who's online, but messages would be cool too. And some sort of event driven notifications of user sign-on would be great, but I'll poll if need be.

  • C# Messagebox With ComboBox

    - by Goober
    How can I produce a messagebox in a C# Win Forms application that displays a combobox with a series of values to select as well as the usual "Ok" button? I would like to be able to trigger this on calling the MessageBox.Show() method. I am assuming some sort of override will be necessary, but I haven't seen any pre-existing examples for this.

  • git pull crashes after other member push something

    - by naiad
    Here it's the story... we have a Github account. I clone the repository ... then I can work with it, commit things, push things, etc ... I use Linux with command line and git version 1.7.7.3 Then other user, using Eclipse and git plugin for eclipse eGit 1.1.0 pushes something, and it appears in the github web pages as the last commit, but when I try to pull: $ git pull remote: Counting objects: 13, done. remote: Compressing objects: 100% (6/6), done. remote: Total 9 (delta 2), reused 7 (delta 0) Unpacking objects: 100% (9/9), done. error: unable to find 3e6c5386cab0c605877f296642d5183f582964b6 fatal: object 3e6c5386cab0c605877f296642d5183f582964b6 not found "3e6c5386cab0c605877f296642d5183f582964b6" is the commit hash of the last commit, done by the other user ... there's no problem at all to browse it through web page ... but for me it's impossible to pull it. It's strange, because my command line output tells about that commit hash, so it knows that one is the last one commit in the github system, but my git can not pull it ! Maybe the git protocol used in eGit is incompatible with the console git 1.7.7.3...

  • How can I import one Gradle script into another?

    - by Ant
    Hi all, I have a complex gradle script that wraps up a load of functionality around building and deploying a number of netbeans projects to a number of environments. The script works very well, but in essence it is all configured through half a dozen maps holding project and environment information. I want to abstract the tasks away into another file, so that I can simply define my maps in a simple build file, and import the tasks from the other file. In this way, I can use the same core tasks for a number of projects and configure those projects with a simple set of maps. Can anyone tell me how I can import one gradle file into another, in a similar manner to Ant's task? I've trawled Gradle's docs to no avail so far. Additional Info After Tom's response below, I thought I'd try and clarify exactly what I mean. Basically I have a gradle script which runs a number of subprojects. However, the subprojects are all Netbeans projects, and come with their own ant build scripts, so I have tasks in gradle to call each of these. My problem is that I have some configuration at the top of the file, such as: projects = [ [name:"MySubproject1", shortname: "sub1", env:"mainEnv", cvs_module="mod1"], [name:"MySubproject2", shortname: "sub2", env:"altEnv", cvs_module="mod2"] ] I then generate tasks such as: projects.each({ task "checkout_$it.shortname" << { // Code to for example check module out from cvs using config from 'it'. } }) I have many of these sort of task generation snippets, and all of them are generic - they entirely depend on the config in the projects list. So what I want is a way to put this in a separate script and import it in the following sort of way: projects = [ [name:"MySubproject1", shortname: "sub1", env:"mainEnv", cvs_module="mod1"], [name:"MySubproject2", shortname: "sub2", env:"altEnv", cvs_module="mod2"] ] import("tasks.gradle") // This will import and run the script so that all tasks are generated for the projects given above. So in this example, tasks.gradle will have all the generic task generation code in, and will get run for the projects defined in the main build.gradle file. In this way, tasks.gradle is a file that can be used by all large projects that consist of a number of sub-projects with Netbeans ant build files.
