  • iphone: is there any secure way to establish 2-way SSL from an application

    - by pmilosev
    Hi I need to establish a HTTPS 2-way SSL connection from my iPhone application to the customer's server. However I don't see any secure way to deliver the client side certificates to the application (it's an e-banking app, so security is really an issue). From what I have found so far the only way that the app would be able to access the certificate is to provide it pre-bundeled with the application itself, or expose an URL from which it could be fetched (http://stackoverflow.com/questions/2037172/iphone-app-with-ssl-client-certs). The thing is that neither of this two ways prevent some third party to get the certificate, which if accepted as a risk eliminates the need for 2-way SSL (since anyone can have the client certificate). The whole security protocol should look like this: - HTTPS 2-way SSL to authenticate the application - OTP (token) based user registration (client side key pair generated at this step) - SOAP / WSS XML-Signature (requests signed by the keys generated earlier) Any idea on how to establish the first layer of security (HTTPS) ? regards

  • LAMP Stack with APC installed - WordPress Site - Is WP opcode being cached with APC?

    - by Christopher Altman
    I have a LAMP stack with APC installed. I have a WordPress site on this server. Is WP taking advantage of the opcode caching? I have done no WP configurations. My understanding is that simply having APC installed means that all PHP code is being cached. If that is untrue, please point me to the direction where I can configure WP to take advantage of APC. Note: I thought about this as a ServerFault question, but since the solution to is code related I posted on Stackoverflow.

  • Python - which multi platform GUI framework to use?

    - by Iacopo
    Hi, I've written a Python GUI application and made it run on Linux, Windows and Mac. The framework I'm using is PyGtk. The final result is not really good: the application looks horrible on Mac, and it is not really 'native' neither on Windows. Furthermore on Mac the windows' behavior is sometimes wrong, with modal dialogs appearing below the main windows. I've explored other frameworks and I've found that a porting may be really hard: PyQt it is huge, difficult to install and to distribute under Mac; PyGui is poor: I need tables and tree views at least; wxPython state explicitly that you have to use a custom python build for Mac Tkinter: didn't check it, only have the impression that it is obsolete I know this question may appear similar to http://stackoverflow.com/questions/394039/which-python-gui-framework but in that thread the portability issue is not really taken in account. Windows and Mac are a must, since most of my user have that systems. Can you also suggest some books?

  • How to effectively draw on desktop in C#?

    - by Lazlo
    I want to draw directly on the desktop in C#. From searching a bit, I ended up using a Graphics object from the Desktop HDC (null). Then, I painted normally using this Graphics object. The problem is that my shapes get lost when any part of the screen is redrawn. I tried a While loop, but it actually ends up drawing as fast as the application can, which is not the update rate of the desktop. Normally, I would need to put my drawing code in a "OnPaint" event, but such thing does not exist for the desktop. How would I do it? Example code: http://stackoverflow.com/questions/1536141/how-to-draw-directly-on-the-windows-desktop-c

  • WMI: How to differentiate between Wireless mouse and touch screen

    - by kingas
    I am using Win32_PointingDevice class to detect mice connected to the system. I ran my device discovery script on a machine which has touch screen. The discovery shows up with 3 pointing devices, directly connected USB mouse, wireless mouse and touch screen. My question is how to distinguish between USB mouse with touch screen. If Win32_PointingDevice class doesn't provide information then are there any other methods which I can use to get mouse and touch information. This is extension to my previous question at http://stackoverflow.com/questions/1746689/wmi-class-for-wireless-mouse

  • Java threadpool functionality

    - by cpf
    Hi stackoverflow, I need to make a program with a limited amount of threads (currently using newFixedThreadPool) but I have the problem that all threads get created from start, filling up memory at alarming rate. I wish to prevent this. Threads should only be created shortly before they are executed. e.g.: I call the program and instruct it to use 2 threads in the pool. The program should create & launch the first 2 Threads immediately (obviously), create the next 2 to wait for the previous 2, and at that point wait until one or both of the first 2 ended executing. I thought about extending executor or FixedThreadPool or such. However I have no clue on how to start there and doubt it is the best solution. Easiest would have my main Thread sleeping on intervals, which is not really good either... Thanks in advance!

  • Silverlight datagrid don't show any data with anonymous query RIA services

    - by user289082
    Hi all! I have an anonymous linq query that I bind to a datagrid, when I debug it brings alright the data but it doesn't show in the datagrid, I suspect that the request to RIA services isn't completed before I bound it to the datagrid. I could use the LoadOperation<() Completed event. But it only works with Defined Entities so how can I do that? For reference here is the last post: http://stackoverflow.com/questions/2403903/linq-query-null-reference-exception Here is the query: var bPermisos = from b in ruc.Permisos where b.IdUsuario == SelCu.Id select new { Id=b.Id, IdUsuario=b.IdUsuario, IdPerfil=b.IdPerfil, Estatus=b.Estatus, Perfil=b.Cat_Perfil.Nombre, Sis=b.Cat_Perfil.Cat_Sistema.Nombre }; I'm a totally newbie sorry if is a very simple question. Thanks!!

  • Using sizeof operator on a typedef-ed struct

    - by sskanitk
    This might be something too obvious. However, I couldn't find the specific answer though many stackoverflow threads talk about different aspects of this. typedef struct _tmp { unsigned int a; unsigned int b; } tmp; int main() { int c=10; if (c <= sizeof tmp) { printf("less\n"); } else { printf("more\n"); } return 0; } I compile this prog as - g++ -lstdc++ a.cpp I get an error - expected primary-expression before ‘)’ token I think I am missing something very obvious and straightforward. But can't seem to pinpoint it :-/ Thanks!

  • Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

    - by Relequestual
    I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made. I was just testing to see how the person would move to a location and back again, and this was the result... http://www.screenjelly.com/watch/Bd7d7pObyFo Different choice of path depending on the direction, an unexpected result. Any ideas?

  • ASP.Net: Finding the cause of OutOfMemoryExpcetions

    - by Keith Bloom
    I trying to track down the cause of an OutOfMemory for a website. This site has ~12,000 .aspx pages and the last time it crashed I captured a memory dump using adplus. After some investigation I found a lot of heap fragmentation, there are around 100MB of Free blocks which can't be assigned. Digging deeper one of the Large Object Heaps is fragmented and the causes seems to be String interning as described [here][1] Could this be caused by the number of pages in the site? As they are all compiled they sit in memory and by looking at the dump they are interned and PINNED which I think means they stick around for a while. I would find this odd as there are many sites with more pages, but dynamic compilation could account for the growth in memory. What other methods are there for finding the cause of the memory leak? I have tried to capture a dump using adplus in hang mode but this fails and the IIS worker process get recycled. [1]: • http://stackoverflow.com/questions/686950/large-object-heap-fragmentation

  • Immutability of big objects

    - by Malax
    Hi StackOverflow! I have some big (more than 3 fields) Objects which can and should be immutable. Every time I run into that case i tend to create constructor abominations with long parameter lists. It doesn't feel right, is hard to use and readability suffers. It is even worse if the fields are some sort of collection type like lists. A simple addSibling(S s) would ease the object creation so much but renders the object mutable. What do you guys use in such cases? I'm on Scala and Java, but i think the problem is language agnostic as long as the language is object oriented. Solutions I can think of: "Constructor abominations with long parameter lists" The Builder Pattern Thanks for your input!

  • Caching issues with TDBadgedCell

    - by Wolfgang Schreurs
    This post is closely related to my previous post: http://stackoverflow.com/questions/2201256/tdbadgedcell-keeps-caching-the-badgenumber The "badge" from TDBadgedCell keeps caching the numbers. A very simple example is shown here: - (UITableViewCell *)tableView:(UITableView *)_tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; TDBadgedCell *cell = (TDBadgedCell *)[_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[TDBadgedCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; } [cell setBadgeColor:[UIColor blackColor]]; [cell setBadgeNumber:[indexPath row]]; [[cell textLabel] setText:[NSString stringWithFormat:%@"%d", [indexPath row]]]; return cell; } Anyone has any clue why this happens? The textLabel and detailTextLabel don't cache the data. Any additonal info would be welcome as well, as I seem to have a lot of issues with the caching of graphics in UITableViewCells. Any best practices or other useful information would be most welcome.

  • Interview question: Check if one string is a rotation of other string.

    - by Webdev
    A friend of mine was asked the following question today at interview for the position of software developer. Given two string s1 and s2 how will you check if s1 is a rotated version of s2 ? Example: if s1 = "stackoverflow"; then the following are some of its rotated versions: "tackoverflows" "ackoverflowst" "overflowstack" where as "stackoverflwo" is not a rotated version. The answer he gave was: Take s2 and find the logest prefix that is a substring of s1, that will give you the point of rotation. Once you find that point, break s2 at that point to get s2a and s2b, then just check if concatenate(s2a,s2b) == s1 It looks like a good solution to me and my friend. But the interviewr though otherwise. He asked for a simpler solution. Please help me by telling how would you do this in Java/C/C++ ? Thanks in advance.

  • javascript "this" points to Window object again

    - by terrani
    Hello, I asked a question on http://stackoverflow.com/questions/2719643/javascript-this-points-to-window-object regarding "this" points to Window object. here is source code var archive = function(){} archive.prototype.action = { test: function(callback){ callback(); }, test2: function(){ console.log(this); } } var oArchive = new archive(); oArchive.action.test(oArchive.action.test2); Tim Down wrote "but that function is then called using callback(), which means it is not called as a method and hence this is the global object". What are differences between calling a function by its actual name and callback() as shown on the source code? How does console.log(this) in test2 points to Window when it is inside archive.action???

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

    - by Rick
    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.

  • How to tell when my batch of EAP calls are completed?

    - by codemonkie
    This is following my question: http://stackoverflow.com/questions/2607038/c-how-to-consume-web-service-adheres-to-the-event-based-asynchronous-pattern My program is calling the DoStuffAsync() x many times in a batch, hence the callback will get invoked the same number of times upon OnComplete(). Is there a way to find out when my batch is finished such that I can generate a report on the success/failed results? All I can think of is to have a static count variable for x and deduct 1 every time OnComplete() is called, but its kind of silly and error prone I'm afraid. TIA.

  • IE error with jquery counter plugin

    - by Mankey
    I've implemented a jquery counter script (count up from say 50 to 100 with different increments) that I found from this question: jQuery counter to count up to a target number The scripts works great except for in Internet Explorer 8 (and possibly other IE versions?). Here's an error message from IE with the URL to the creator of the script's demo. Message: 'undefined' is null or not an object Line: 32 Char: 17 Code: 0 URI: http://www.ulmanen.fi/stuff/counter.php I'm just wondering if anyone know how this can be fixed. I'm guessing it has to do with el.html() not finding any data but I can't really figure this out. Thanks for any help ^^ I would reply to that post if I could but I can't seem to find any way of doing so (I'm new to stackoverflow, I think I lack privileges).

  • Python: how to run several scripts (or functions) at the same time under windows 7 multicore processor 64bit

    - by Gianni
    sorry for this question because there are several examples in Stackoverflow. I am writing in order to clarify some of my doubts because I am quite new in Python language. i wrote a function: def clipmyfile(inFile,poly,outFile): ... # doing something with inFile and poly and return outFile Normally I do this: clipmyfile(inFile="File1.txt",poly="poly1.shp",outFile="res1.txt") clipmyfile(inFile="File2.txt",poly="poly2.shp",outFile="res2.txt") clipmyfile(inFile="File3.txt",poly="poly3.shp",outFile="res3.txt") ...... clipmyfile(inFile="File21.txt",poly="poly21.shp",outFile="res21.txt") I had read in this example Run several python programs at the same time and i can use (but probably i wrong) from multiprocessing import Pool p = Pool(21) # like in your example, running 21 separate processes to run the function in the same time and speed my analysis I am really honest to say that I didn't understand the next step. Thanks in advance for help and suggestion Gianni

  • Find folder name based on string value with batch

    - by MaQleod
    I need to return a full directory name from inside a specified directory that contains .default in the folder name. Basically I'm adding a line in a backup script to backup firefox bookmarks, but the profile name is going to be different on every machine and I need a way to find the folder the bookmarks.html file resides without knowing the firefox profile name I've looked at FIND and FINDSTR but neither seem to be what I need. I also looked at this post: http://stackoverflow.com/questions/2252785/windows-batch-file-get-folders-path-and-store-them-in-variable It was closer to what I'm looking for, but I just need a folder name, and to use something like regexp to find it Any suggestions on commands to look at or strategies to use?

  • Haskell IO Passes to Another Function

    This question here is related to http://stackoverflow.com/questions/3066956/haskell-input-return-tuple I wonder how we can passes the input from monad IO to another function in order to do some computation. Actually what i want is something like -- First Example test = savefile investinput -- Second Example maxinvest :: a maxinvest = liftM maximuminvest maxinvestinput maxinvestinput :: IO() maxinvestinput = do str <- readFile "C:\\Invest.txt" let cont = words str let mytuple = converttuple cont let myint = getint mytuple putStrLn "" -- Convert to Tuple converttuple :: [String] -> [(String, Integer)] converttuple [] = [] converttuple (x:y:z) = (x, read y):converttuple z -- Get Integer getint :: [(String, Integer)] -> [Integer] getint [] = [] getint (x:xs) = snd (x) : getint xs -- Search Maximum Invest maximuminvest :: (Ord a) => [a] -> a maximuminvest [] = error "Empty Invest Amount List" maximuminvest [x] = x maximuminvest (x:xs) | x > maxTail = x | otherwise = maxTail where maxTail = maximuminvest xs In the second example, the maxinvestinput is read from file and convert the data to the type maximuminvest expected. Please help. Thanks.
