  • Does lamda in List.ForEach leads to memory leaks and performance problems ?

    - by Monomachus
    I have a problem which I could solve using something like this sortedElements.ForEach((XElement el) => PrintXElementName(el,i++)); And this means that I have in ForEach a lambda which permits using parameters like int i. I like that way of doing it, but i read somewhere that anonymous methods and delegates with lambda leads to a lot of memory leaks because each time when lambda is executed something is instantiated but is not released. Something like that. Could you please tell me if this is true in this situation and if it is why?

  • Chrome ne supportera plus le H.264, Google ne veut soutenir que « des technologies et des codecs complètement ouverts »

    Chrome ne supportera plus le H.264 Google ne veut soutenir que « des technologies et des codecs complètement ouverts » Le billet de Google s'intitule « HTML Video Codec Support in Chrome ». Mais il aurait aussi bien pu s'appeler « pourquoi nous abandonnons le H.264 ». Chrome prend donc le même chemin que Firefox et ne supportera plus ? en natif tout du moins ? le codec vidéo soutenu par Apple. Motif invoqué : le H.264 est fermé et propriétaire. « Nous supportons WebM (VP8) et Theora, et nous envisageons d'ajouter à l'avenir le support d'autres codecs ouvertes et de qualité », écrit Mike Jazayeri, Product Manager chez Google. « Bien que...

  • Mac OS X : Moutain Lion disponible le mois prochain avec la dictée intégrée, les notifications et encore plus d'iCloud

    Mac OS X : Moutain Lion disponible le mois prochain avec la dictée intégrée, les notifications et beaucoup d'iCloud Le WWDC d'Apple est traditionnellement riche en annonce. Cette année, en plus d'iOS 6, la société a également présenté les améliorations en cours pour son prochain OS desktop (alias « Moutain Lion »). Sur les 200 listés par Craig Federighi, c'est avant tout iCloud qui a été mis en avant. La plateforme de stockage et de synchronisation hébergée prendra en charge Messages, Notes, Rappels ou Documents. iCloud synchronisera également les onglets de Safari (unifiant ainsi le surf entre Mac et iOS) et le Game Center (qui débarque sur bureau donc).

  • Intentionally breaking iPhone + Exchange communication [closed]

    - by Stafford Williams
    I've (accidently) found a way to construct an email that will cause an iPhone to be unable to download any emails from the Exchange folder this email is present in. The only way to fix this issue, is to go the account outside the phone (web/outlook) and delete the email. I've tested this against windows and android phones, and they are not affected. When trying to determine what was the cause of this issue I found several posts like this one offering possible resolutions, but they did not seem to be related to this specific issue (I also tried most of the solutions, including some from apple, but none of them fixed the issue) Should I report this issue and how its recreated to someone? If so, who/where?

  • What production software have you written in F# in the past year or so that you would previously hav

    - by Peter McGrattan
    Over the last few years F# has evolved into one of Microsoft's fully supported languages employing many ideas incubated in OCaml, ML and Haskell. Over the last several years C# has extended it's general purpose features by introducing more and more functional language features: LINQ (list comprehension), Lamdas, Closures, Anonymous Delegates and more... Given C#'s adoption of these functional features and F#'s taxonomy as an impure functional language (it allows YOU to access framework libraries or change shared state when a function is called if you want to) there is a strong similarity between the two languages although each has it's own polar opposite primary emphasis. I'm interested in any successful models employing these two languages in your production polyglot programs and also the areas within production software (web apps, client apps, server apps) you have written in F# in the past year or so that you would previously have written in C#.

  • iOS NSError with global handler

    - by Sebastian Dressler
    I am in the beginning of programming an iOS app. Having read the Apple guides on how to deal with errors, I got the following most important points: Exceptions are for programmers Use NSError for the user Now, NSError is usually passed as out-argument which can then be used inside and has to be checked by the caller. However, I'm asking myself whether it is a good idea to use a global error handler, say a singleton which wraps around NSError and could be used to trigger errors and error handling from within the called function. Is there anything against that method or would it be a bad practice?

  • Added a tableview in a viewcontroller. How do I load tableview cells

    - by user1509593
    I have a view controller In storyboard, added tableview to view controller. Created an IBOutlet for tableview to View controller's header file. The view controller's header file includes an resultsarray Changed the @interface to include delegates <\UITableViewDelegate, UITableViewDataSource View controller implementation file has mandatory tableview protocols (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath The view controller has search button in storyboard and IBAction in view controller header file. On click of search button, results are obtained. How do I load the array and redisplay tableview with results in search method. After I loaded the results in array, I tried [self viewdidload];, hoping the cells will be loaded. But didn't. I thought of calling [self.detailView cellForRowAtIndexPath:?indexpath], but dontknow what the value of index path is. Appreciate help from guru's to load the UItableviewcell Thanks

  • Is age a factor when looking for internships? [closed]

    - by user786362
    Possible Duplicate: Is it ever too old to learn how to become a programmer? I'm 30 years old going back to school for a 2nd degree in Computer Science. I will be transferring to my local state university this fall and would like to know if my age will be a factor when applying for internships. I have already read a few threads about age and careers: Is it too late to start your career as a programmer at the age of 30? Does it matter that you started developing at 26? While it is reassuring to know that people are getting entry-level programming jobs at 30+, what about internships? Should I even bother with bigger companies like Google, Microsoft, or Apple? I know we have laws against age-discrimination but lets not pretend we live in a perfect world where everyone follows the rules.

  • Game Design - When to separate out pieces into static libraries?

    - by Jason
    I am developing a game that has a lot of platform generic pieces. I am wanting to separate out various pieces into static libraries and I would like to know what other devs do. I am considering targeting other platforms and I want to maintain an much platform neutrality as I can. I have a lot of generic level data in C++ classes. THinking all of the level data could go into a single static library. I have a lot of generic OpenGL code that I think could also go into a single static library. I am already using CMAKE for some and XCode 4.5 for the Apple specific pieces. What do other devs do to stay platform neutral? Does anyone use Eclipse instead of XCode and Visual Studio on Windows?

Les Google Glass suscitent beaucoup d'intérêt de la part de la concurrence. Après Apple, c'est au tour de Microsoft de se lancer dans ce genre de projet. L'éditeur qui avait promis qu'il sortirait d'autres appareils que la Surface (et la Xbox 360) sous sa marque propre pourrait bien tenir parole avec des lunettes.

  • Why do we need the "event" keyword while defining events ?

    - by Puneet Dudeja
    I don't understand why do we need the "event" keyword while defining events, when we can do the same thing without using "event" keyword, just by using the delegates. e.g. public delegate void CustomEventHandler(int a, string b); public event CustomEventHandler customEvent; customEvent += new CustomEventHandler(customEventHandler); customEvent(1,"a"); // Raising the event Here if I remove the "event" keyword from the second line, then also I can raise the event by invoking the delegate. Can anybody please tell me why is this event keyword needed ?

  • Les conditions d'utilisation de l'App Store seraient incompatibles avec la licence GPL, l'application libre VLC vient d'en faire les frais

    Les conditions d'utilisation de l'App Store seraient incompatibles avec la licence GPL, l'application libre VLC vient d'en faire les frais On vous a offert un iPhone à Noël et vous vouliez y installer un lecteur multi codecs gratuit sur votre terminal ? Trop tard. L'application VLC vient d'être supprimée de l'App Store, où elle est désormais "persona non grata". Ceux qui possèdent déjà le logiciel pourront en revanche le conserver. Quel a été le problème ?

  • Is there ongoing work in the kernel team to improve battery life under linux?

    - by leousa
    I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

  • Why does IDLE continue to crash? [migrated]

    - by Dyana
    Idle keeps crashing and I can't figure it out. After restarting the computer and reinstalling Python, none of which seemed to work, I looked to my peers and was told to "install one of the Tcl/Tk". After getting another opinion I was also told that I already had this and found it to be true but decided to try it anyway since it continued to crash. Nothing has improved and I have an assignment due. Any ideas on why this continues to happen and what I can do to fix the crash?

  • Excel Add-in memory explosion

    - by tsinik
    I wrote a small .NET add in to excel 2007 that read data from external c++ api and display it inside an excel. The task manager shows that I'm having a memory leak (the memory usage is inflate linearly up to 250MB after whitch it throws an "Excel cannot complete this task with available resources error") but the problem disappears as soon as I minimize the excel window. The api uses delegates to return data and I update it into a dictionary. another thread is updating the excel from the dictionary every second. It is unlikely that the unmanaged code is responsible of the leak. Does anybody have an idea what can cause this? 10x!

  • If we write iOS and sell on App Store, are we protected for legal consequences? [closed]

    - by ????
    Will the developer or company (is a corporation or is not) be responsible for legal consequences, or will they be covered and protected by the Apple Store Terms of Use agreement? For example: 1) the app is fun and the kids show the app to a parent who is driving the car, and got into an accident. 2) if the app does road navigation and it went into problem or crash or slow, and caused an accident while driving. 3) or if the terms require using an app in a safe and non-time critical situation, what if the app recommend some exercise routine or diet (such as suggesting eating more eggs, milk, or using some herbs), and it could be argued that they caused any health consequence?

  • Are there Any Concerns with Importing Document Files From a Competing Product?

    - by Thunderforge
    I have a new product that serves the same purpose as my competitor's long-standing product. One thing I have considered doing is allowing my program to import document files created by their product in order to provide an easy way for users to migrate towards mine. Naturally, this would be done without the competitor's permission, as it goes against their interests. I've seen this done before with office suite software (e.g. Open Office and Apple Pages can import MS Word documents), but I'm wondering if there are any concerns, legal or ethical, with me doing this. I fully expect any answers will most likely fall under the "I am not a lawyer" clause, but it would be helpful to have a starting point for anything I would need to be aware of, or if I shouldn't need to worry.
