• Git Status Across Multiple Repositories on a Mac

  - by eapen

  I have been searching for a solution to this for a while and have not found quite what I need. I have several Git Repositories in a folder on my Mac (OSX 10.6) and would like a script or tool that will loop through all the repositories and let me know if any of them needs "commit"-ing. This is my structure Sites   /project1   /project2   /project3 I want the tool to do a "git status" in Sites/project1, Sites/project2, Sites/project3 and let me know if Sites/project2 and Sites/project3 have changes or new files and needs to be Staged/committed The closest script I found that might be hackable is here: http://gist.github.com/371828 but even that script wouldn't run and I get an error: "syntax error near unexpected token `do" which might have been written for *nix.

• A PHP object server for business logic

  - by Matthieu

  I wonder if such a thing is possible or even exist : In the MVC pattern, I would like to have the Model part to be persistant in memory, instead of reloading my instances at each execution. So I want only the Controller and View part to be executed. Is there any solution of server that would provide PHP objects (just like a Mysql server provides data records), and that keeps these objects in memory ? A problem would be also : how to have a constructed query to get objects ? Maybe PHP Linq ?

• Element Positioning affected by Browser Screen Resolution Change

  - by Ed

  Hello, newbie developer here. There's this small problem I always encounter. Every time I try to change browser resolution (or what do you call the event when you scroll the mouse wheel while pressing ctrl), some elements (Mostly form elements) get to be shifted down or somewhere else, which does not conform with the original positioning. Im not sure if the problem is with the CSS or the markup itself and Im not really sure if this is much of a problem. Should I ignore it? (It doesn't feel very comfortable though, thinking that it might become problematic in the near future) Otherwise, any solution on how to avoid this? Simple explanations are very much appreciated, Thanks. (Perhaps the used term newbie should be replaced with noob?. Haha.)

• PagedDataSource does not support serialization - how can I enforce this ?

  - by Darkyo

  Sounds like I want to override a physics law, but at least it is the most reasonnable solution, cpu / HDD and Ram effective for my asp.net project. In fact, I got a pageddataSource and a customDataReader that supports paginated data. The truth is my data are in a viewstate variable, because it is re-used in an update panel. When I intend to use it into my pageddatasource, asp.net 3.5 kills me with a System.Web.UI.WebControls.PagedDataSource' in Assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable. cool exception... So I'd rather not offend newton because I know he'll always win, but I would need some help to enforce this pagedDataSource law, that seems so unbelievable, except if someone has an explanation.

• Standalone jQuery "touch" method?

  - by dclowd9901

  So, I'm looking to implement the ability for a plugin I wrote to read a touch "swipe" from a touch-capable internet device, like an iPhone, iPad or android. Is there anything out there? I'm not looking for something as full as jQtouch, though was considering reverse engineering the code I would need out of it. Any suggestions on the best way to approach this? A snippet of code already available? Addendum: I realize in hindsight the solution won't strictly be jQuery, as I'm pretty sure there aren't any built-in methods to handle this. I would expect standard Javascript to find itself in the answer.

• Plotting 3D Polygons in python-matplotlib

  - by Developer

  I was unsuccessful browsing web for a solution for the following simple question: How to draw 3D polygon (say a filled rectangle or triangle) using vertices values? I have tried many ideas but all failed, see: from mpl_toolkits.mplot3d import Axes3D from matplotlib.collections import PolyCollection import matplotlib.pyplot as plt fig = plt.figure() ax = Axes3D(fig) x = [0,1,1,0] y = [0,0,1,1] z = [0,1,0,1] verts = [zip(x, y,z)] ax.add_collection3d(PolyCollection(verts),zs=z) plt.show() I appreciate in advance any idea/comment. Updates based on the accepted answer: import mpl_toolkits.mplot3d as a3 import matplotlib.colors as colors import pylab as pl import scipy as sp ax = a3.Axes3D(pl.figure()) for i in range(10000): vtx = sp.rand(3,3) tri = a3.art3d.Poly3DCollection([vtx]) tri.set_color(colors.rgb2hex(sp.rand(3))) tri.set_edgecolor('k') ax.add_collection3d(tri) pl.show() Here is the result:

• Implementing sub fields in a PropertyGrid

  - by evolve

  Alright so my terminology when it comes to C# isn't great, so I'll attempt to explain this with a small example. If you create a class which you are using within a PropertyGrid and you have the following values: class Test { public Point example { get; set; } } This will produce a PropertyGrid which has an expandable object "example" which has fields X and Y in order to create a "Point". I'm attempting to create an object "name" which has fields "firstname" and "lastname", so I have: class Test { public Name example { get; set; } } public struct Name { public string firstname { get; set; } public string lastname { get; set; } } This however isn't working as intended. I think I need to override some method(s) in order to get this working, however since I don't really have the terminology down for PropertyGrids it is difficult for me to find a solution. Any help would be great.

• How to redefine symbol names in objects with RVCT?

  - by Batuu

  I currently develop a small OS for an embedded platform based on a ARM Cortex-M3 microcontroller. The OS provides an API for customer application development. The OS kernel and the API is compiled into a static lib by the ARMCC compiler and customer can link his application against it. The lib and the containing object files offer the complete list of symbols used in kernel. To "protect" the kernel and its inner states from extern hooking into obvious variables and functions, I would like to do some easy obfuscation by renaming the symbols randomly. The GNU binutils seems to do this by calling objcopy with the --redefine-sym flag. The GNU binutils cannot read the ARMCC / RVCT objects. Is there any solution to do this kind of obfuscation with RVCT?

• How to extract delegates from ViewController class?

  - by adranle

  Hi I have the problem that my view controller class has too many delegates and starts to get big. I want to write the delegates in separate classes to keep the view controller class small. For delegates that are programmatically created (like UIAlertViewDelegate) I could do it easily. The problem is in the delegates assigned in Interface Builder. How can I tell the IB to assign, for example, another class as the UITableViewDelegate or UITableViewDataSource? Or how to choose another IBAction method for a Touch UP inside Event on a button? One solution would be to delete the connections from IB and write them programmatically at ViewDidLoad, but since I have a lot of ViewControllers, this would take a long time. any other ideas?

• Initial conditions with a non-linear ODE in Mathematica

  - by buggy

  Hi, I'm trying to use Mathematica's NDSolve[] to compute a geodesic along a sphere using the coupled ODE: x" - (x" . x) x = 0 The problem is that I can only enter initial conditions for x(0) and x'(0) and the solver is happy with the solution where x" = 0. The problem is that my geodesic on the sphere has the initial condition that x"(0) = -x(0), which I have no idea how to tell mathematica. If I add this as a condition, it says I'm adding True to the list of conditions. Here is my code: s1 = NDSolve[{x1''[t] - (x1[t] * x1''[t] + x2[t] * x2''[t] + x3[t]*x3''[t]) * x1[t] == 0, x2''[t] - (x1[t] * x1''[t] + x2[t] * x2''[t] + x3[t]*x3''[t]) * x2[t] == 0, x3''[t] - (x1[t] * x1''[t] + x2[t] * x2''[t] + x3[t]*x3''[t]) * x3[t] == 0, x1[0] == 1, x2[0] == 0, x3[0] == 0, x1'[0] == 0, x2'[0] == 0, x3'[0] == 1} , { x1, x2, x3}, {t, -1, 1}][[1]] I would like to modify this so that the initial acceleration is not zero but -x(0). Thanks

• Retrieving values from WSDL before making a request

  - by Egor

  I'm very new to working with web services and I'm trying to understand the basics of it in Android using the ksoap2 library. Here's the question: this is the WSDL file of a service I'm using. It's a service that converts values between different units. The units are stated in the WSDL. Now, is there any way to read those units and, say, populate a Spinner to let users choose the units they want to work with? A code solution will be highly appreciated. Thanks in advance.

• C++ template class error with operator ==

  - by Tommy

  Error: error C2678: binary '==' : no operator found which takes a left-hand operand of type 'const entry' (or there is no acceptable conversion) The function: template <class T, int maxSize> int indexList<T, maxSize>::search(const T& target) const { for (int i = 0; i < maxSize; i++) if (elements[i] == target) //ERROR??? return i; // target found at position i // target not found return -1; } indexList.h indexList.cpp Is this suppose to be an overloaded operator? Being a template class I am not sure I understand the error? Solution- The overload function in the class now declared const: //Operators bool entry::operator == (const entry& dE) const <-- { return (name ==dE.name); }

• Strategy in storing ad-hoc numbers/constants?

  - by Jiho Han

  I have a need to store a number of ad-hoc figures and constants for calculation. These numbers change periodically but they are different type of values. One might be a balance, a money amount, another might be an interest rate, and yet another might be a ratio of some kind. These numbers are then used in a calculation that involve other more structured figures. I'm not certain what the best way to store these in a relational DB is - that's the choice of storage for the app. One way, I've done before, is to create a very generic table that stores the values as text. I might store the data type along with it but the consumer knows what type it is so, in situations I didn't even need to store the data type. This kind of works fine but I am not very fond of the solution. Should I break down each of the numbers into specific categories and create tables that way? For example, create Rates table, and Balances table, etc.?

• Running junit tests in parallel ?

  - by krosenvold

  I'm using junit 4.4 and maven and I have a large number of long-running integration tests. When it comes to parallellizing test suites there are a few solutions that allow me to run each test method in a single test-class in parallel. But all of these require that I change the tests in one way or another. I really think it would be a much cleaner solution to run X different test classes in X threads in parallel. I have hundreds of tests so I don't really care about threading individual test-classes. Is there any way to do this ?

• Enumerating all combinations of lists of different types

  - by jball

  Given two IEnumberables of different types, what is the best practice (considering readability and maintainability) for iterating over both lists to perform an action on all possible combinations? My initial solution was to use nested foreach loops, iterating over the first IEnumerable, and then within that loop, iterating over the second IEnumerable and passing the value from the outer and the current loop into the target method. Eg.: enum ParamOne { First, Second, Etc } List<int> paramTwo = new List<int>() { 1, 2, 3 }; void LoopExample() { foreach (ParamOne alpha in Enum.GetValues(typeof(ParamOne))) { foreach (int beta in paramTwo) { DoSomething(alpha, beta); } } } I tried to restructure it with LINQ, but ended up with something that had no obvious advantages and seemed less intuitive. A search here shows lots of questions about nesting foreachs to iterate over child properties, but I couldn't find anything about iterating over two distinct lists.

• How should I port this Prototype to JQuery?

  - by blu

  There is currently this Prototype code that does a PUT: new Ajax.Request(someUrl, { method: 'put', parameters: { 'foo': bar }, onSuccess: function(response) { } .bind(this) }); I found this post but the solution uses an extra parameter supported by RoR, however I am targeting an ASP.NET backend. I searched a bit and found that not all browsers support PUT operations so apparently this could fail in certain browsers? This is already in prod, so a direct port would be fine for now I suppose. As an aside, what is the deal with the bind(this) in the onSuccess function?

• Working with the Objective-C/Cocoa flat namespace

  - by Stephen Blinkhorn

  I've not found anything that addresses my specific name space question as yet. I am working on some AudioUnit plug-ins featuring Cocoa based GUIs. The plug-ins use a common library of user interface classes (sliders, buttons etc) which are simply added to each Xcode project. When I recompile and distribute updates it is pretty much guaranteed that at least one user interface class will have been updated since the last release. If the user launches an older plug-in before an updated plug-in then the old Cocoa classes are already loaded into the run time and the plug-in attempts to use the older implementations - often resulting in a failure one way or another. I know frameworks are the intended solution but the overhead and backwards compatibility issues are not ideal. I prefix all class names where possible but what options do I have to ensure that each plug-in contains unique class names for the shared user interface classes?

• CSS/HTML: Highlighting the "full width avaialble" to a list item

  - by JoshuaD

  I'm working on a website for a small law office. In the side-menu, I'm trying to highlight the "current page". I have tried changing the background of the LI, but this doesn't quite do the trick; the list item doesn't spread to the full width of the menu, so it looks bad. Here's a jfiddle. I would like the yellow section to highlight like the pink section is highlighted: filling up the full vertical and horizontal space, not just highlighting the text. Any suggestions on how to do this? I've included the style tag in the html just for example, obviously, and my real solution will be a little different when it's done. But I can't move forward until I figure out how to somehow highlight the entire line.

• phonegap crossplatform redirection to local file

  - by Marco Gagliardi

  Hi I'm developing a phonegap + JQueryMobile app, which should be correctly executed on Android, iOs and WindowsPhone as well. I need to exploit an external service wich requires one callback url to redirect the app to in case of success, and one in case of error (pretty common situation. In my case both will be local files, say www/success.html and www/error.html). Of course I could write different paths for each device (e.g. file:///android_asset/www/success.html on Android), but i'm wondering if the framework provide a more simple elegant solution. So the questions is, how can i get a unique absolute URL wich allows me to perform a cross-platform HTTP redirection from a remote web page to a local file within a phonegap application? Thanks

• How can I ensure that a Java object (containing cryptographic material) is zeroized?

  - by Jeremy Powell

  My concern is that cryptographic keys and secrets that are managed by the garbage collector may be copied and moved around in memory without zeroization. As a possible solution, is it enough to: public class Key { private char[] key; // ... protected void finalize() throws Throwable { try { for(int k = 0; k < key.length; k++) { key[k] = '\0'; } } catch (Exception e) { //... } finally { super.finalize(); } } // ... }

• sql select puzzle: remove children when parent is filtered out

  I have a table essentially: name has_children parent_id row_id values0.....valuesn parent 1 1 1 children 0 1 2 children 0 1 3 parent 0 4 4 parent 1 5 5 children 0 5 6 children 0 5 7 the values for the children can be different than the values for the parent. i want some selects/joins that will filter the table on a value column (i.e. 10) and will return the parent (even if false for the filter) if one of it's children is true for the filter. acceptable return: parent=true all children=false, return just parent parent=false >=1 children=true, return parent and one non-filtered child i'm sure this has been thought about before but i don't have the faintest idea how to phrase the question to find a solution.

• How to change the order of toolbar buttons in Internet Explorer?

  I know I can simply write to the CommandBandLayout regkey but since I don't know what format it is I'm having doubts if that is safe. Also, this answer suggest it's the wrong solution: http://stackoverflow.com/questions/1239266/how-to-modify-commandbandlayout-reg-key-value But how can I change the order a bit? I have written an Internet Explorer Add-on and I've registered it by putting it in HKCU but by default it falls off the screen so users are having trouble finding it. I would like to make the bar wider or move the button back in the screen.
