  • Are there Negative Impact of opensource on commercial environment?

    - by Lostsoul
    I know this is not a good fit for Stack Overflow but wasn't sure if it was good for this site also so let me know if its not and I'll delete it. I love programming for fun but my role in my company is not technical. I have always loved the hacker culture and have been trying to drive that openness within my company from day one. My company has a very broad range of products and there are a few that are not strategic to us so I wanted to open source them (so we can focus on what makes us unique and open source the products that every firm has). Our industry does not open source(we would be the first firm to try this) and the feedback I'm getting from my management team is either 1) we'll destroy the industry or 2) all competitive commercial firms will unite against us and we'll be wiped out either way. I disagreed on both points because I think transparency will only grow our industry and our firm (think of McDonalds/KFC sharing their recipe openly, people may copy you, competitors may target you, but customers also may feel more comfortable buying your product. The value add, I believe, is in the delivery and experience not in hoarding the recipe). It's a big battle in my firm right now between the IT people who have seen the positive effects of sharing and the business people who think we'll be giving up everything (they prefer we sell parts we want to opensource, but in their defense this is standard when divesting something). Our industry is very secretive and I don't want to put anyone(even my competitors employees) out of a job yet I don't want to protect inefficient people by not being open with everyone. Yet I've seen so many amazing technologies created in interesting ways just by giving people freedom to take apart code and put it back together. I'm interested in hearing people's thoughts(doesn't have to be to my specific situation, I'm looking for the general lessons). Its a very stressful decision(but one I feel I must make) because if we go the open source route then there will be no going back. So what are your thoughts? Does open sourcing apply generally or is it only really applicable to software? Is it overall good for people in the industry and outside? I'm actually more interested in the negativeness effects(although positive are welcomed as well) Update: Long story short, although code is involved this is not so much about code as it is more about the idea of open sourcing. We are a mid sized quant hedge fund. We have some unique strategies but also have the standard long/short, arbitrage, global macro, etc.. funds. We are keeping the unique funds we have but the other stuff that everyone else has we are considering open sourcing (We have put in years of work & millions of dollars into. Our funds is pretty popular and our performance is either in first or second quartile so I suspect there will be interest but I don't know to what extent). The goal is not to get a community to work for us or anything, the goal is to let anyone who wants to tinker with it do so and create anything they want (it will not be part of our product line although I may unofficially allocate some our of staff's time to assist any community that grows). Although the code base is quite large, the value in this is the industry knowledge and approaches we have acquired (there are many books on artificial intelligence and quant trading but they are often years behind what's really going on as most firms forbid their staff from discussing what they are doing). We are also considering after we move our clients out to let the software still run and output the resulting portfolios for free as well so people can at least see the results(as long as we have avail. infrastructure). I think our main choices are, we can continue to fight for market share in a products that are becoming commoditized, we can shut the funds/products down(and keep the code but no one outside of our firm will ever learn from it) or we can open source it and let people do what they want. By open sourcing it, my idea is that the talent pool in the industry will grow because right now most of our hires have the same background (CFA, MBA, similar school, same experience,etc.. because we can't spend time training people so the industry 'standardizes' most people and thus the firms themselves start to look/act similar) but this may allow us to identify talent that has never been in the industry before (if we put a GPU license then as people learn from what we did, we can learn from what they do as well and maybe apply it to other areas of our firm). I see a lot of benefits but not many negatives while my peers at the company see the opposite.

  • Unable to resolve class in build.gradle using Android Studio 0.60/Gradle 0.11

  • How to diagnose cause, fix, or work around Adobe ActiveX / COM related error 0x80004005 progmaticall

    - by Streamline
    I've built a C# .NET app that uses the Adobe ActiveX control to display a PDF. It relies on a couple DLLs that get shipped with the application. These DLLs interact with the locally installed Adobe Acrobat or Adobe Acrobat Reader installed on the machine. This app is being used by some customer already and works great for nearly all users ( I check to see that the local machine is running at least version 9 of either Acrobat or Reader already ). I've found 3 cases where the app returns the error message "Error HRESULT E_FAIL has been returned from a call to a COM component" when trying to load (when the activex control is loading). I've checked one of these user's machines and he has Acrobat 9 installed and is using it frequently with no problems. It does appear that Acrobat 7 and 8 were installed at one time since there are entries for them in the registry along with Acrobat 9. I can't reproduce this problem locally, so I am not sure exactly which direction to go. The error at the top of the stacktrace is: System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component. Some research into this error indicates it is a registry problem. Does anyone have a clue as to how to fix or work around this problem, or determine how to get to the core root of the problem? The full content of the error message is this: System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.    at System.Windows.Forms.UnsafeNativeMethods.CoCreateInstance(Guid& clsid, Object punkOuter, Int32 context, Guid& iid)    at System.Windows.Forms.AxHost.CreateWithoutLicense(Guid clsid)    at System.Windows.Forms.AxHost.CreateWithLicense(String license, Guid clsid)    at System.Windows.Forms.AxHost.CreateInstanceCore(Guid clsid)    at System.Windows.Forms.AxHost.CreateInstance()    at System.Windows.Forms.AxHost.GetOcxCreate()    at System.Windows.Forms.AxHost.TransitionUpTo(Int32 state)    at System.Windows.Forms.AxHost.CreateHandle()    at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)    at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)    at System.Windows.Forms.AxHost.EndInit()    at AcrobatChecker.Viewer.InitializeComponent()    at AcrobatChecker.Viewer..ctor()    at AcrobatChecker.Form1.btnViewer_Click(Object sender, EventArgs e)    at System.Windows.Forms.Control.OnClick(EventArgs e)    at System.Windows.Forms.Button.OnClick(EventArgs e)    at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)    at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)    at System.Windows.Forms.Control.WndProc(Message& m)    at System.Windows.Forms.ButtonBase.WndProc(Message& m)    at System.Windows.Forms.Button.WndProc(Message& m)    at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)    at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)    at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

  • Landscape orientation for UITabBarController?

    - by gingersnap
    The UITabBarController does not allow landscape orientation. So I used a subclass of UITabBarContoller (called RotatingTabBarController). Its sole purpose it to allow rotation by returning YES to shouldAutorotateToInterfaceOrientation call. The problem is that when you rotate the iPhone in simulator it gives the following malloc error. malloc: *** error for object 0x3888000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I am using 3.0 SDK with Xcode 3.2 on Snow Leopard. I set a breakpoint in malloc_error_break but I can not trace it back to my code. Is there something I can do to make this error go away? Here is the RotatingTabBarController class: #import <UIKit/UIKit.h> @interface RotatingTabBarController : UITabBarController { } @end @implementation RotatingTabBarController -(BOOL)shouldAutorotateToInterfaceOrientation:UIInterfaceOrientation)interfaceOrientation { return YES; } @end Update: I tried the same with a category. But it gives the same malloc error. // UITabBarController+Rotation.h @interface UITabBarController (rotation) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation; @end // UITabBarController+Rotation.m #import "UITabBarController+Rotation.h" @implementation UITabBarController (rotation) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end Backtrace [Session started at 2009-09-05 12:13:19 -0400.] Untitled(992,0xa06d9500) malloc: *** error for object 0x2024000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Untitled(992,0xa06d9500) malloc: *** error for object 0x2014000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug [Session started at 2009-09-05 12:13:27 -0400.] GNU gdb 6.3.50-20050815 (Apple version gdb-1344) (Fri Jul 3 01:19:56 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

  • mysql never releases memory

    - by Ishu
    I have a production server clocking about 4 million page views per month. The server has got 8GB of RAM and mysql acts as a database. I am facing problems in handling mysql to take this load. I need to restart mysql twice a day to handle this thing. The problem with mysql is that it starts with some particular occupation, the memory consumed by mysql keeps on increasing untill it reaches the maximum it can consume and then mysql stops responding slowly or does not respond at all, which freezes the server. All my tables are indexed properly and there are no long queries. I need some one to help on how to go about debugging what to do here. All my tables are myisam. I have tried configuring the parameters key_buffer etc but to no rescue. Any sort of help is greatly appreciated. Here are some parameters which may help. mysql --version mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 mysql> show variables;

  • jBASE 4.1 Database Noobster Questions

    - by Steve Johnson
    I am a software developer with devlopment experience in C#, C++ .Net alongwith SQL Server 2005/08, Oracle and mysql. But somehow i dont get jBASE to work at Windows XP SP3 machine. My goal is setup user accounts, create database on a JBASE ainstallation, authenticate and backup/restore few table via a C++ program. And i dont need to do it with builtin backup/restore tools of jBASE. I am able to install jBASe 4.1 aling with all its accessories on my WINXPSP3 machine. I was able to run the jSlimserver and TEMENOUS server along with licnesing server. I was able to add the license key as well. But after that what i was supposed to do? i have no idea about it. The docs and online help doesnt answer a simple question of how to create a database! The google search results from the jbase site all go to the 404 Pages! Can a jBASE expert guide to the following steps: Create a jBASE database. Create users Authenticate via those users Connect to database Create tables and insert data. Connect via a C++ or C# program to connect to jBASE DB and backup/restore tables. I know that this is too much too ask but i dont get to get the JBASE system. I cant get it to work on my System somehow. Btw, jdc and jexloree doesnt seem to do anything. I have checked that enironmental variables for jBASE are setup correctly and i have verified them. There are no extra JRE or JDK installations on my system. Besides all that, only licensing client, slim server and temenous server seem to run and listen for connections and no other execuatable ever seems to work. A simple tutorial to achieve the objective will be highly appreciated. Also if anyone can point out the mistake that i have done or anything i might need to check, then please do so. I will be highly encouraged and obliged. Thanks Steve

  • What do you expect from a package manager for Emacs

    - by tarsius
    Although several hundred Emacs Lisp libraries exist GNU Emacs does not have an (internal) package manager. I guess that most users would agree that it is currently rather inconvenient to find, install and especially keep up-to-date Emacs Lisp libraries. These pages make life a bit easier Emacs Lisp List - Problem: I see dead people (links). Emacswiki - Problem: May contain traces of nuts (malicious code). These are some package managers XEmacs package manager package.el - ELPA pases install.el install-elisp.el plugin.el use-package.el jem-pkg.el epkg/elm - the one I am working. And this are some packages that provide functionality that might be useful in a package manager ell.el - Browse the Emacs Lisp List genauto.el - helps generate autoloads for your elisp packages date-calc.el - date calculation and parsing routines strptime.el - partial implementation of POSIX date and time parsing wikirel.el - Visit relevant pages on the Emacs Wiki loadhist.el, lib-requires.el, elisp-depend.el - Commands to list Emacs Lisp library dependencies. project-root.el - Define a project root and take actions based upon it So I would like to know from you what you consider important/unimportant/supplementary... in a package manager for Emacs. Some ideas Many packages (incorporate the Emacs Lisp List and other lists of libraries). Only packages that have been tested. Support for more than one package archive (so people can choose between many/tested packages). Dependency calculated based on required features only. Dependencies take particular versions into account. Only use versions that have been released upstream. Use versions from version control systems if available. Packages are categorized. Packages can be uninstalled and updated not only installed. Support creating fork of upstream version of packages. Support publishing these forks. Support choosing a fork. After installation packages are activated. Generate autoloads. Integration with Emacswiki (see wikirel.el). Users can tag, comment ... packages and share that information. Only FSF-assigned/GPL/FOSS software or don't care about license. Package manager should be integrated in Emacs. Support contacting author. Lots of metadata. Suggest alternatives before installing a particular package. Some discussions about the subject at hand emacs-devel 20080801 comp.emacs 20021121 RationalElispPackaging I am hoping for these kinds of answers Pointers to more implementations, discussions etc. Lengthy descriptions of a set of features that make up your ideal package manager. Descriptions of one particular disired/undisired feature. This has the advantage that the regular voting mechanism allows us to see what features are most welcomed. Feel free to elaborate on my ideas from above. Surprise me.

  • Easiest Way To Get Started In Dot Net

    - by Avery Payne
    Ok, so the initial search in StackOverflow shows nothing related for this question. So here it goes: Let's pretend for a moment that you're just getting started in a career in computer programming. Let's say that, for whatever reason, you decide to use the .Net framework as a basis for your programming. Let's also say that you've been exposed to some programming background, but not one in .Net, so it seems foreign to you at first. And lastly, you don't have the benefit of 25 years of exposure to the Win32 API, which explains why it seems so foreign to you when you start looking at it. So the questions are: What is a comprehensive overview of what .Net is? It appears to be a combination of a runtime environment, a set of languages, a common set of libraries, and perhaps a few other things...so it's about as clear as mud. Specifically, what are the key components to .Net? What is the easiest way to understand .Net programming with regard to available APIs? Which language would best suit beginning programming out of the "stock" languages that Microsoft has to offer? (C++, C#, VB, etc.) What are some differences between .Net programming and programming in a procedural language (aka Pascal, Modula, etc.) What are some differences between .Net programming and programming in a "traditional" object-oriented language? (aka Smalltalk, Java, Python, Ruby, etc.) As I currently understand it, the CLR provides a foundation for all of the other languages to run on. What are some of the inherent limitations of the CLR? Given the enormous amount of API to cover, would it even be worth learning a .Net language (using the Microsoft APIs) given that you would not have prior exposure to Win32 programming? Let's say you write a for-profit program with .Net. Can you resell the program without running afoul of licensing issues? Let's say you write a gratis (free) program with .Net. Can you offer the program to the public under a "free" license (GPL, BSD, Artistic, etc.) without running afoul of licensing issues? Thank you in advance for your patience.

  • How do I construct a Django reverse/url using query args?

    - by Andrew Dalke
    I have URLs like http://example.com/depict?smiles=CO&width=200&height=200 (and with several other optional arguments) My urls.py contains: urlpatterns = patterns('', (r'^$', 'cansmi.index'), (r'^cansmi$', 'cansmi.cansmi'), url(r'^depict$', cyclops.django.depict, name="cyclops-depict"), I can go to that URL and get the 200x200 PNG that was constructed, so I know that part works. In my template from the "cansmi.cansmi" response I want to construct a URL for the named template "cyclops-depict" given some query parameters. I thought I could do {% url cyclops-depict smiles=input_smiles width=200 height=200 %} where "input_smiles" is an input to the template via a form submission. In this case it's the string "CO" and I thought it would create a URL like the one at top. This template fails with a TemplateSyntaxError: Caught an exception while rendering: Reverse for 'cyclops-depict' with arguments '()' and keyword arguments '{'smiles': u'CO', 'height': 200, 'width': 200}' not found. This is a rather common error message both here on StackOverflow and elsewhere. In every case I found, people were using them with parameters in the URL path regexp, which is not the case I have where the parameters go into the query. That means I'm doing it wrong. How do I do it right? That is, I want to construct the full URL, including path and query parameters, using something in the template. For reference, % python manage.py shell Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information.

  • What is the best python module skeleton code?

    - by user213060
    == Subjective Question Warning == Looking for well supported opinions or supporting evidence. Let us assume that skeleton code can be good. If you disagree with the very concept of module skeleton code then fine, but please refrain from repeating that opinion here. Many python IDE's will start you with a template like: print 'hello world' That's not enough... So here's my skeleton code to get this question started: My Module Skeleton, Short Version: #!/usr/bin/env python """ Module Docstring """ # ## Code goes here. # def test(): """Testing Docstring""" pass if __name__=='__main__': test() and, My Module Skeleton, Long Version: #!/usr/bin/env python # -*- coding: ascii -*- """ Module Docstring Docstrings: http://www.python.org/dev/peps/pep-0257/ """ __author__ = 'Joe Author ([email protected])' __copyright__ = 'Copyright (c) 2009-2010 Joe Author' __license__ = 'New-style BSD' __vcs_id__ = '$Id$' __version__ = '1.2.3' #Versioning: http://www.python.org/dev/peps/pep-0386/ # ## Code goes here. # def test(): """ Testing Docstring""" pass if __name__=='__main__': test() Notes: """ ===MODULE TYPE=== Since the vast majority of my modules are "library" types, I have constructed this example skeleton as such. For modules that act as the main entry for running the full application, you would make changes such as running a main() function instead of the test() function in __main__. ===VERSIONING=== The following practice, specified in PEP8, no longer makes sense: __version__ = '$Revision: 1.2.3 $' for two reasons: (1) Distributed version control systems make it neccessary to include more than just a revision number. E.g. author name and revision number. (2) It's a revision number not a version number. Instead, the __vcs_id__ variable is being adopted. This expands to, for example: __vcs_id__ = '$Id: example.py,v 1.1.1.1 2001/07/21 22:14:04 goodger Exp $' ===VCS DATE=== Likewise, the date variable has been removed: __date__ = '$Date: 2009/01/02 20:19:18 $' ===CHARACTER ENCODING=== If the coding is explicitly specified, then it should be set to the default setting of ascii. This can be modified if necessary (rarely in practice). Defaulting to utf-8 can cause anomalies with editors that have poor unicode support. """ There are a lot of PEPs that put forward coding style recommendations. Am I missing any important best practices? What is the best python module skeleton code? Update Show me any kind of "best" that you prefer. Tell us what metrics you used to qualify "best".

  • Objective-C: properties not being saved or passed

    - by Gerald Yeo
    Hi, i'm a newbie to iphone development. I'm doing a navigation-based app, and I'm having trouble passing values to a new view. @interface RootViewController : UITableViewController { NSString *imgurl; NSMutableArray *galleryArray; } @property (nonatomic, retain) NSString *imgurl; @property (nonatomic, retain) NSMutableArray *galleryArray; - (void)showAll; @end #import "RootViewController.h" #import "ScrollView.h" #import "Model.h" #import "JSON/JSON.h" @implementation RootViewController @synthesize galleryArray, imgurl; - (void)viewDidLoad { UIBarButtonItem *showButton = [[[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Show All", @"") style:UIBarButtonItemStyleBordered target:self action:@selector(showAll)] autorelease]; self.navigationItem.rightBarButtonItem = showButton; NSString *jsonString = [[Model sharedInstance] jsonFromURLString:@"http://www.ddbstaging.com/gerald/gallery.php"]; NSDictionary *resultDictionary = [jsonString JSONValue]; if (resultDictionary == nil) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Webservice Down" message:@"The webservice you are accessing is currently down.

I can see it from the first console trace. However, once I click on the Show All button, the app crashes. It doesn't even trace the galleryArray and imgurl properyly. Maybe additional pairs of eyes can spot my mistakes. Any help is greatly appreciated!

  • [NSIS] Custom radio-buttom INI page via Eclipse

    - by Omegazero
    I'm using Eclipse's create InstallOptions menu to create a custom INI page with radio-buttons for repackaging the Blackberry Desktop installer. There are 2 sections for each type: "Internet" and "Enterprise". I need a user to select 1 of the 2 options and depending on their selection, the page will carry over the selection chosen in the custom page, jump to the INSTFILES page, and continue onto the end. I couldn't find any concrete documentation on getting INI pages to load in the script (I'm probably searching incorrectly), and then pass data from one page to the next (according to fields I guess?) Any help is appreciated.

  • How can I edit an entity in MVC4 with EF5 which has a unique constraint?

    - by Yoeri
    [HttpPost] public ActionResult Edit(Car car) { if (ModelState.IsValid) { db.Entry(car).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } return View(car); } This is a controller method scaffolded by MCV 4 My "car" entity has a unique field: LicensePlate. I have custom validation on my Entity: Validation: public partial class Car { partial void ValidateObject(ref List<ValidationResult> validationResults) { using (var db = new GarageIncEntities()) { if (db.Cars.Any(c => c.LicensePlate.Equals(this.LicensePlate))) { validationResults.Add( new ValidationResult("This licenseplate already exists.", new string[]{"LicensePlate"})); } } } } should it be usefull, my car entity: public partial class Car:IValidatableObject { public int Id { get; set; } public string Color { get; set; } public int Weight { get; set; } public decimal Price { get; set; } public string LicensePlate { get; set; } public System.DateTime DateOfSale { get; set; } public int Type_Id { get; set; } public int Fuel_Id { get; set; } public virtual CarType Type { get; set; } public virtual Fuel Fuel { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { var result = new List<ValidationResult>(); ValidateObject(ref result); return result; } partial void ValidateObject(ref List<ValidationResult> validationResults); } QUESTION: Everytime I edit a car, it raises an error: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details. The error is the one raised by my validation, saying it can't edit because there is already a car with that license plate. If anyone could point me in the right direction to fix this, that would be great! I searched but couldn't find anything, so even related posts are welcome!

  • How to stream semi-live audio over internet

    - by Thomas Tempelmann
    I want to write something like Skype, i.e. I have a constant audio stream on one computer and then recompress it in a format that's suitable for a latent internet connection, receive it on the other end and play it. Let's also assume that the internet connection is fairly modern and fast, i.e. DSL or alike, no slow connections over phone and such. The involved computers will also be rather modern (Dual Core Intel CPUs at 2GHz or more). I know how to handle the audio on the machines. What I don't know is how to transmit the audio in an efficient way. The challenges are: I'd like get good audio quality across the line. The stream should be received without drops. The stream may, however, be received with a little delay (a second delay is acceptable). I imagine that the transport software could first determine the average (and max) latency, then start the stream and tell the receiver to wait for that max latency before starting to play the audio. With that, if the latency doesn't get any higher, the entire stream will be playable on the other side without stutter or drops. If, due to unexpected IP latencies or blockages, the stream does get cut off, I want to be able to notice this so that I can take actions (e.g. abort the stream) and eventually start a new transmission. What are my options if I want do use ready-made software for the compression and tranmission? I have no intention to write my own audio compression engine, really. OTOH, I plan to sell the solution in a vertical market, meaning I can afford a few dollars of license fees per copy, but not $100s. I guess the simplest solution would be to just open a TCP stream, send a few packets back and forth to determine their running time (or even use UDP for that), then use the results as the guide for my max latency value, then simply fire the audio data in its raw form (uncompressed 16 bit stereo), along with a timing code over the TCP connection. The receiver reads the data and plays it with the pre-determined delay. That might just work with the type of fast connection I expect. I just wonder if there are better solutions to reach this goal, with better performance (lower latency) and less data (compressed). BTW, I first try to implement this on OS X, but might want to do it on Windows, too, if it proves successful.

  • A NSMutableArray is destroying my life!

    - by camilo
    EDITED to show the relevant part of the code Hi. There's a strange problem with an NSMutableArray which I'm just not understanding... Explaining: I have a NSMutableArray, defined as a property (nonatomic, retain), synthesized, and initialized with 29 elements. realSectionNames = [[NSMutableArray alloc] initWithCapacity:29]; After the initialization, I can insert elements as I wish and everything seems to be working fine. While I'm running the application, however, if I insert a new element in the array, I can print the array in the function where I inserted the element, and everything seems ok. However, when I select a row in the table, and I need to read that array, my application crashes. In fact, it cannot even print the array anymore. Is there any "magical and logical trick" everybody should know when using a NSMutableArray that a beginner like myself can be missing? Thanks a lot. I declare my array as realSectionNames = [[NSMutableArray alloc] initWithCapacity:29]; I insert objects in my array with [realSectionNames addObject:[category categoryFirstLetter]]; although I know i can also insert it with [realSectionNames insertObject:[category categoryFirstLetter] atIndex:i]; where the "i" is the first non-occupied position. After the insertion, I reload the data of my tableView. Printing the array before or after reloading the data shows it has the desired information. After that, selecting a row at the table makes the application crash. This realSectionNames is used in several UITableViewDelegate functions, but for the case it doesn't matter. What truly matters is that printing the array in the beginning of the didSelectRowAtIndexPath function crashes everything (and of course, doesn't print anything). I'm pretty sure it's in that line, for printing anything he line before works (example): NSLog(@"Anything"); NSLog(@"%@", realSectionNames); gives the output: 2010-03-24 15:16:04.146 myApplicationExperience[3527:207] Anything [Session started at 2010-03-24 15:16:04 +0000.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

  • Delegates does not work properly

    I am new to iPhone development. I am converting the date to the desired format and set it to the delegate and get its value in the another view. The session restarts when I tried to get the value from delegate. If I set the original date and not the formatted date in the set delegate, then i able to get the value in the another view. If I also give any static string value, then also I am able to the static string value back. Only the formatted date which is string is set then the session restarts. If i print and check the value of the formatted date it prints the correct formatted date only.Please help me out.Here is my code for date conversion NSString *dateval=[[stories objectAtIndex: storyIndex] objectForKey:@"date"]; NSDateFormatter *inputFormatter = [[NSDateFormatter alloc] init]; [inputFormatter setDateFormat:@"EEE, MMM dd, yyyy"]; NSDate *inputDate = [inputFormatter dateFromString:dateval]; NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init]; [outputFormatter setDateFormat:@"MMMM dd"]; NSString *outputDate = [outputFormatter stringFromDate:inputDate]; AppDelegate *delegate=(AppDelegate *)[[UIApplication sharedApplication]delegate]; [delegate setCurrentDates:outputDate]; EDIT: This is displayed in console inside view did load [Session started at 2010-04-21 19:12:53 +0530.] GNU gdb 6.3.50-20050815 (Apple version gdb-967) (Tue Jul 14 02:11:58 UTC 2009) Copyright 2004 Free Software Foundation, Inc.

  • Installing a clean Python 2.6 on SuSE (SLES) 11 using system-wide libraries

    Hi, I've spent most of the day on this, and it is driving me absolutely insane. On all other Unixes I've used, this is a walk in the park, but SLES 11 has me dumbfounded. I need to build Zope on SLES 11 64 bit: Linux <name> 2.6.27.45-0.1-default #1 SMP 2010-02-22 16:49:47 +0100 x86_64 x86_64 x86_64 GNU/Linux I first tried to just use the YaST-installed Python 2.6. I've also installed python-devel, libjpeg-devel, readline-devel, libopenssl-devel, libz2-devel, zlib-devel, and libgcrypt-devel. The global python2.6 has a lot of cruft in it, and seems to execute stuff in /etc/pythonstart when I use it, which doesn't help. However, the error I get is this: Getting distribution for 'Zope2==2.12.3'. src/AccessControl/cAccessControl.c:596: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:598: warning: ‘intargfunc’ is deprecated src/AccessControl/cAccessControl.c:598: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:599: warning: ‘intargfunc’ is deprecated src/AccessControl/cAccessControl.c:599: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:600: warning: ‘intintargfunc’ is deprecated src/AccessControl/cAccessControl.c:600: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:601: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:602: warning: initialization from incompatible pointer type src/AccessControl/cAccessControl.c:606: warning: ‘intargfunc’ is deprecated src/AccessControl/cAccessControl.c:606: warning: initialization from incompatible pointer type /usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: skipping incompatible /usr/lib/libpython2.6.so when searching for -lpython2.6 /usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: cannot find -lpython2.6 collect2: ld returned 1 exit status error: Setup script exited with error: command 'gcc' failed with exit status 1 An error occured when trying to install Zope2 2.12.3. Look above this message for any errors that were output by easy_install. I don't know what "incompatible" is referring to here; my guess would be the hardware architecture, but I'm not sure what's incompatible with what in the statement above. I've had problems with system-installed Pythons before, so I tried to compile my own (hence the list of -devel packages above), downloading the Python 2.6 tarball and running: ./configure --disable-tk --prefix=${HOME}/python make make install This installs, but it seems to be unable to find any system-wide libraries. Here's a sample interpreter session: Python 2.6.5 (r265:79063, Mar 29 2010, 17:04:12) [GCC 4.3.2 [gcc-4_3-branch revision 141291]] on linux2 Type "help", "copyright", "credits" or "license" for more information. Traceback (most recent call last): File "/etc/pythonstart", line 7, in <module> import readline ImportError: No module named readline >>> from hashlib import md5 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/osc/python-2.6/lib/python2.6/hashlib.py", line 136, in <module> md5 = __get_builtin_constructor('md5') File "/home/osc/python-2.6/lib/python2.6/hashlib.py", line 63, in __get_builtin_constructor import _md5 ImportError: No module named _md5 Both readline and hashlib (via libgrypt) should be installed, and the relevant -devel packages are also installed. On Ubuntu or OS X, this works just fine. On SuSE, no luck. Any help greatly appreciated! Martin

  • Sharing the same `ssh-agent` among multiple login sessions

    - by intuited
    Is there a convenient way to ensure that all logins from a given user (ie me) use the same ssh-agent? I hacked out a script to make this work most of the time, but I suspected all along that there was some way to do it that I had just missed. Additionally, since that time there have been amazing advances in computing technology, like for example this website. So the goal here is that whenever I log in to the box, regardless of whether it's via SSH, or in a graphical session started from gdm/kdm/etc, or at a console: if my username does not currently have an ssh-agent running, one is started, the environment variables exported, and ssh-add called. otherwise, the existing agent's coordinates are exported in the login session's environment variables. This facility is especially valuable when the box in question is used as a relay point when sshing into a third box. In this case it avoids having to type in the private key's passphrase every time you ssh in and then want to, for example, do git push or something. The script given below does this mostly reliably, although it botched recently when X crashed and I then started another graphical session. There might have been other screwiness going on in that instance. Here's my bad-is-good script. I source this from my .bashrc. # ssh-agent-procure.bash # v0.6.4 # ensures that all shells sourcing this file in profile/rc scripts use the same ssh-agent. # copyright me, now; licensed under the DWTFYWT license. mkdir -p "$HOME/etc/ssh"; function ssh-procure-launch-agent { eval `ssh-agent -s -a ~/etc/ssh/ssh-agent-socket`; ssh-add; } if [ ! $SSH_AGENT_PID ]; then if [ -e ~/etc/ssh/ssh-agent-socket ] ; then SSH_AGENT_PID=`ps -fC ssh-agent |grep 'etc/ssh/ssh-agent-socket' |sed -r 's/^\S+\s+(\S+).*$/\1/'`; if [[ $SSH_AGENT_PID =~ [0-9]+ ]]; then # in this case the agent has already been launched and we are just attaching to it. ##++ It should check that this pid is actually active & belongs to an ssh instance export SSH_AGENT_PID; SSH_AUTH_SOCK=~/etc/ssh/ssh-agent-socket; export SSH_AUTH_SOCK; else # in this case there is no agent running, so the socket file is left over from a graceless agent termination. rm ~/etc/ssh/ssh-agent-socket; ssh-procure-launch-agent; fi; else ssh-procure-launch-agent; fi; fi; Please tell me there's a better way to do this. Also please don't nitpick the inconsistencies/gaffes ( eg putting var stuff in etc ); I wrote this a while ago and have since learned many things.
