  • Comment les firmes répartissent-elles leurs dépenses pour les composants de leurs smartphones ? Un tableau interactif le montre

    Comment les firmes répartissent-elles leurs dépenses pour les composants de leurs smartphones ? Un tableau interactif le montre La firme américaine Tableau Software propose un tableau interactif qui permet d'en savoir plus sur les dépenses des firmes pour la fabrication de leurs smartphones. Si le prix moyen de la conception est assez semblable d'un modèle à l'autre, en revanche la façon dont les entreprises répartissent leurs dépenses varie de l'un à l'autre, et en fonction des composants. Par exemple, Apple fait les plus grosses dépenses pour les coques de ses téléphones ; Nokia ne compte pas lorsqu'il s'agit d'objectif caméra, etc. Source :

  • Blog Buzz - Devoxx 2011

    - by Janice J. Heiss
    Some day I will make it to Devoxx – for now, I’m content to vicariously follow the blogs of attendees and pick up on what’s happening.  I’ve been doing more blog "fishing," looking for the best commentary on 2011 Devoxx. There’s plenty of food for thought – and the ideas are not half-baked.The bloggers are out in full, offering useful summaries and commentary on Devoxx goings-on.Constantin Partac, a Java developer and a member of Transylvania JUG, a community from Cluj-Napoca/Romania, offers an excellent summary of the Devoxx keynotes. Here’s a sample:“Oracle Opening Keynote and JDK 7, 8, and 9 Presentation•    Oracle is committed to Java and wants to provide support for it on any device.•    JSE 7 for Mac will be released next week.•    Oracle would like Java developers to be involved in JCP, to adopt a JSR and to attend local JUG meetings.•    JEE 7 will be released next year.•    JEE 7 is focused on cloud integration, some of the features are already implemented in glassfish 4 development branch.•    JSE 8 will be release in summer of 2013 due to “enterprise community request” as they can not keep the pace with an 18    month release cycle.•    The main features included in JSE8 are lambda support, project Jigsaw, new Date/Time API, project Coin++ and adding   support for sensors. JSE 9 probably will focus on some of these features:1.    self tuning JVM2.    improved native language integration3.    processing enhancement for big data4.    reification (adding runtime class type info for generic types)5.    unification of primitive and corresponding object classes6.    meta-object protocol in order to use type and methods define in other JVM languages7.    multi-tenancy8.    JVM resource management” Thanks Constantin! Ivan St. Ivanov, of SAP Labs Bulgaria, also commented on the keynotes with a different focus.  He summarizes Henrik Stahl’s look ahead to Java SE 8 and JavaFX 3.0; Cameron Purdy on Java EE and the cloud; celebrated Java Champion Josh Bloch on what’s good and bad about Java; Mark Reinhold’s quick look ahead to Java SE 9; and Brian Goetz on lambdas and default methods in Java SE 8. Here’s St. Ivanov’s account of Josh Bloch’s comments on the pluses of Java:“He started with the virtues of the platform. To name a few:    Tightly specified language primitives and evaluation order – int is always 32 bits and operations are executed always from left  to right, without compilers messing around    Dynamic linking – when you change a class, you need to recompile and rebuild just the jar that has it and not the whole application    Syntax  similarity with C/C++ – most existing developers at that time felt like at home    Object orientations – it was cool at that time as well as functional programming is today    It was statically typed language – helps in faster runtime, better IDE support, etc.    No operator overloading – well, I’m not sure why it is good. Scala has it for example and that’s why it is far better for defining DSLs. But I will not argue with Josh.”It’s worth checking out St. Ivanov’s summary of Bloch’s views on what’s not so great about Java as well. What's Coming in JAX-RS 2.0Marek Potociar, Principal Software Engineer at Oracle and currently specification lead of Java EE RESTful web services API (JAX-RS), blogged on his talk about what's coming in JAX-RS 2.0, scheduled for final release in mid-2012.  Here’s a taste:“Perhaps the most wanted addition to the JAX-RS is the Client API, that would complete the JAX-RS story, that is currently server-side only. In JAX-RS 2.0 we are adding a completely interface-based and fluent client API that blends nicely in with the existing fluent response builder pattern on the server-side. When we started with the client API, the first proposal contained around 30 classes. Thanks to the feedback from our Expert Group we managed to reduce the number of API classes to 14 (2 of them being exceptions)! The resulting is compact while at the same time we still managed to create an API that reflects the method invocation context flow (e.g. once you decide on the target URI and start setting headers on the request, your IDE will not try to offer you a URI setter in the code completion). This is a subtle but very important usability aspect of an API…” Obviously, Devoxx is a great Java conference, one that is hitting this year at a time when much is brewing in the platform and beginning to be anticipated.

  • How to do firmware updates/upgrades to a Blackberry

    - by Luis Alvarado
    I have several clients/friends that have Blackberry and wish to update their phone but without installing Windows. Any windows. Just doing it from Ubuntu. How can this be done. The update the mention is for the firmware and new programs for the phone. I do not know much about Blackberries since am more of an android guy. At the end they want support for upgrade/update the Blackberry from within Linux and sync it to the PC (Backups, upload/download stuff to and from it). I have seen 2 types of projects working on this: Linberry (From Venezuela ;) ) - http://linberry.webcindario.com/ Barry - http://www.netdirect.ca/software/packages/barry but so far neither offers updating the firmware or downloading updates. Are there any Ubuntu blackberry projects I am not aware of.

  • Problems detecting android tablet IView 788TPC with mtp-tools

    - by Elder Geek
    I installed mtp-tools on 14.04 "Trusty" through Software Center. No problems with install. Issuing `mtp-detect' results in 'Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6 Listing raw device(s) No raw devices found.' I did some research and found that mtpfs might be required. so installed that with :~$ sudo apt-get install mtpfs I still get the following result :~$ mtp-detect Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6 Listing raw device(s) No raw devices found. My research indicates that the mtp-tools package is still under development. source: http://libmtp.sourceforge.net/ and the documentation is not comprehensive. source man mtp-tools as well as mtp-detect -h I tried adding the PPA from Are there any plans to improve mtp support on future Ubuntu releases? but it seems this is already worked into trusty 14.04 and won't resolve the problem. Can anyone provide a recommended course of action to resolve this problem?

  • Performance tracking/monitoring in games

    - by vitaliy kotik
    Let's say I have an online game with a downloadable client / browser plugin. I want to track performance of my software and automatically send summary to the server. Let it be fps, latency, load time, physics step calc. time, whatever... I also want tools to perform data analysis: per session stats, per hardware stats, avgs, totals, diagrams, etc. So that I could see what are the real world hotspots / bottlenecks. Is there any common out-of-the-box / SaS solution?

  • Renovación de equipos antiguos y los TCO

    - by Eloy M. Rodríguez
    Acabo de ver un vídeo de Oracle sobre las ventajas económicas y de eficiencia que aportan los programas en marcha de renovación de base instalada. Con los recientes anuncios de los SPARC T4 y SuperCluster las ventajas se refuerzan. Y en España sigue habiendo una importante base instalada de sistemas Sun en la sanidad. En el vídeo me ha llamado la atención que se destaque algo que casi nunca se hace: el reciclado de los sistemas antiguos. Son tres minutos y medio y es muy fácil de seguir por sus grafismos y por el inglés muy entendible con que se expresa el presentador. Al final, estamos hablando de TCO, el cada vez más famoso Coste Total de Propiedad, tema que cada vez debería de tomar peso a la hora de las decisiones sobre el coste de adquisición. Prueba de ello es que el gobierno de Gran Bretaña ha publicado una primera guía de criterios de consideración a la hora del cálculo del TCO de productos de software. Animo a echarle un vistazo, porque pone en papel organizadamente lo que todos conocemos, pero que siempre es bueno tenerlo sistematizado.

  • What do you do when you realize your job requires you to do something out of your depth?

    - by Billy ONeal
    For a large software project recently, I was really out of my depth. And I did actually know this; and that the only reason I was employed was mostly a lack of other qualified candidates. The job was to build a large application on top of PHP/MySQL, a system I had little experience with. (I did advise the employer of this beforehand -- I've been spoiled by C# ASP.NET/MVC and MSSQL Server) The main reason I applied was location, location, location -- on campus jobs which actually have any programming component are relatively rare. For almost a year and a half I've slogged through this, and I think I can say I know (at least somewhat) what I'm doing now. I've made some mistakes, torn out some hair, and moved on. (I'm still working on this system nowadays, but I no longer feel completely lost) In the future though, I'd like to keep my personal and professional self a little healthier than what occurred in this case. So I'm curious -- what's the best way to handle a situation like this?

  • Approach on working with many programmers on one module/feature

    - by Panoy
    How can 2 or more developers code a certain feature/module of a software? Let's assume that the module is big and feature rich. How would they prevent each other from overlapping their code? Say, we have the same method but is implemented in a different way. Do you think it might be better to have one focused at a specific feature only? Is a version control system like Git would help solve the problem? Is it correct that it allows developers to have these "branches" and then merge it later on? What's your take on this?

  • Samsung NP305U1A laptop won't resume from suspension

    - by Oskar Pålsson
    I just bought a Samsung NP305U1A laptop and installed Ubuntu Desktop 12.04 LTS on it. Whenever I suspend the computer and try to wake it back up, the monitor only shows a black screen and the only thing I can do is a hard reset. Kernel: 3.2.0-24-generic Graphic: Radeon HD 6320 Anybody know what to do? UPDATE I did some some research and remebered that I installed the "ATI/AMD proprietary FGLRX graphics driver" from the "Additional drivers" software bundled in Ubuntu. I also tried to install the "ATI/AMD proprietary FGLRX graphics driver (post-release updates)" but whenever I do, it gives me an error and I can't continue So I decided to make a clean install of Ubuntu 12.04 again and when i tried the suspension out-of-the-box, it did work. But since I can't install the drivers I need, HD video is choppy like hell. So perhaps the suspension bug was fixed in the post-release updates of the driver, but sadly I cannot install them, and I don't know why.

  • Architecture Forum in the North 2010 - Hosted by Black Marble

    - by Stuart Brierley
    On Thursday the 8th of December I attended the "Architecture Forum in the North 2010" hosted by Black Marble. The third time this annual event has been held, it was pitched as featuring Black Marble and Microsoft UK architecture experts focusing on “Tools and Methods for Architects.... a unique opportunity to provide IT Managers, IT and software architects from Northern businesses the chance to learn about the latest technologies and best practices from Microsoft in the field of Architecture....insightful information about the latest techniques, demonstrating how with Microsoft’s architecture tools and technologies you can address your current business needs." Following a useful overview of the Architecture features of Visual Studio 2010, the rest of the day was given over to various features and ways to make use of Microsoft's Azure offerings.  While I did feel that a wider spread of technologies could have been covered (maybe a bit of Sharepoint or BizTalk even), the technological and architectural overviews of the Azure platform were well presented, informative and useful. The day was well organised and all those involved were friendly and approachable for questions and discussions.  If you are in "the North" and get a chance to attend next year I would highly recommend it.

  • Are there any non-english programming languages? [closed]

    - by samarudge
    Possible Duplicate: Non-English-based programming languages Not sure if this is the right place to ask this, but I'm going to anyway. Without fail, every programming language I've ever seen, used or heard of has it's keywords based around English. if, else, while, for, query, foreach, image, path, extension, the list goes on, are all based around English words. Are there any languages, or ports of languages that base their core keywords based on non-english words to lower the wall for non-english speaking programmers? This is mostly for intrest (English is my first language so it's no problem for me). Are these languages popular locally (I.E. might a software development house in Germany use a programming language based in German over one based in English).

  • Script to only execute during first install of a package

    - by Jeroen
    I recently started packaging up some of my software and publishing it on Launchpad. The installation and removal works fine, but upgrading the package form one version to the next version is problematic. The problem is that there are some scripts that only need to run during the first installation of the package. These scripts populate the DB, create a user, etc. They are currently called in the package.postinst configure) section. However this results in them being called during an upgrade as well as shown in the diagram. Is there a way to include a maintainer script in a .deb package that only executes during the first installation of the package and not during an upgrade? Or what would be an elegant way to include some initial setup scripts in a .deb package?

  • Video Training Courses for Linux/Ubuntu?

    - by Anil
    I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.

  • C++ Library API Design

    - by johannes
    I'm looking for a good resource for learning about good API design for C++ libraries, looking at shared objects/dlls etc. There are many resources on writing nice APIs, nice classes, templates and so on at source level, but barely anything about putting things together in shared libs and executables. Books like Large-Scale C++ Software Design by John Lakos are interesting but massively outdated. What I'm looking for is advice i.e. on handling templates. With templates in my API I often end up with library code in my executable (or other library) so if I fix a bug in there I can't simply roll out the new library but have to recompile and redistribute all clients of that code. (and yes, I know some solutions like trying to instantiate at least the most common versions inside the library etc.) I'm also looking for other caveats and things to mind for keeping binary compatibility while working on C++ libraries. Is there a good website or book on such things?

  • How do I route my SMTP outgoing mail through gmail (Google Mail) ?

    - by Paula DiTallo
    Here is the quick answer:  Go into your client e software (e.g. Outlook, Thunderbird, etc.) for the account you are working on (usually default). Set the SMTP server to smtp.gmail.com Set the username as your gmail account user name (e.g. [email protected]). Gmail will need the username and password you use for that account, so if your default is set to some other email, be sure to set the username and password to that value, or click on the checkbox for username/password. Check TLS as the secure connection.   If you are looking for more in-depth info, check out Gina Trapani 's block on the topic.

  • How to choose a job? [closed]

    - by Aadi Droid
    When given multiple opportunities from various software giants, as a fresher out of school how should one decide which company to go for? Just as an example I have offers from two companies, won't name them but the two biggest dream companies for any SDE. While one company offers tremendous learning opportunites and and a good pay but coupled with really bad employee support and perks. While the other offers a relaxed work environment where learning happens by choice, with a slightly lower pay but amazing employee facilities and perks. Assuming the fresher has a plan to go for his masters degree in two years what are the most important things he should be looking at?

  • Extreme Optimization – Numerical Algorithm Support

    - by JoshReuben
    Function Delegates Many calculations involve the repeated evaluation of one or more user-supplied functions eg Numerical integration. The EO MathLib provides delegate types for common function signatures and the FunctionFactory class can generate new delegates from existing ones. RealFunction delegate - takes one Double parameter – can encapsulate most of the static methods of the System.Math class, as well as the classes in the Extreme.Mathematics.SpecialFunctions namespace: var sin = new RealFunction(Math.Sin); var result = sin(1); BivariateRealFunction delegate - takes two Double parameters: var atan2 = new BivariateRealFunction (Math.Atan2); var result = atan2(1, 2); TrivariateRealFunction delegate – represents a function takes three Double arguments ParameterizedRealFunction delegate - represents a function taking one Integer and one Double argument that returns a real number. The Pow method implements such a function, but the arguments need order re-arrangement: static double Power(int exponent, double x) { return ElementaryFunctions.Pow(x, exponent); } ... var power = new ParameterizedRealFunction(Power); var result = power(6, 3.2); A ComplexFunction delegate - represents a function that takes an Extreme.Mathematics.DoubleComplex argument and also returns a complex number. MultivariateRealFunction delegate - represents a function that takes an Extreme.Mathematics.LinearAlgebra.Vector argument and returns a real number. MultivariateVectorFunction delegate - represents a function that takes a Vector argument and returns a Vector. FastMultivariateVectorFunction delegate - represents a function that takes an input Vector argument and an output Matrix argument – avoiding object construction  The FunctionFactory class RealFromBivariateRealFunction and RealFromParameterizedRealFunction helper methods - transform BivariateRealFunction or a ParameterizedRealFunction into a RealFunction delegate by fixing one of the arguments, and treating this as a new function of a single argument. var tenthPower = FunctionFactory.RealFromParameterizedRealFunction(power, 10); var result = tenthPower(x); Note: There is no direct way to do this programmatically in C# - in F# you have partial value functions where you supply a subset of the arguments (as a travelling closure) that the function expects. When you omit arguments, F# generates a new function that holds onto/remembers the arguments you passed in and "waits" for the other parameters to be supplied. let sumVals x y = x + y     let sumX = sumVals 10     // Note: no 2nd param supplied.     // sumX is a new function generated from partially applied sumVals.     // ie "sumX is a partial application of sumVals." let sum = sumX 20     // Invokes sumX, passing in expected int (parameter y from original)  val sumVals : int -> int -> int val sumX : (int -> int) val sum : int = 30 RealFunctionsToVectorFunction and RealFunctionsToFastVectorFunction helper methods - combines an array of delegates returning a real number or a vector into vector or matrix functions. The resulting vector function returns a vector whose components are the function values of the delegates in the array. var funcVector = FunctionFactory.RealFunctionsToVectorFunction(     new MultivariateRealFunction(myFunc1),     new MultivariateRealFunction(myFunc2));  The IterativeAlgorithm<T> abstract base class Iterative algorithms are common in numerical computing - a method is executed repeatedly until a certain condition is reached, approximating the result of a calculation with increasing accuracy until a certain threshold is reached. If the desired accuracy is achieved, the algorithm is said to converge. This base class is derived by many classes in the Extreme.Mathematics.EquationSolvers and Extreme.Mathematics.Optimization namespaces, as well as the ManagedIterativeAlgorithm class which contains a driver method that manages the iteration process.  The ConvergenceTest abstract base class This class is used to specify algorithm Termination , convergence and results - calculates an estimate for the error, and signals termination of the algorithm when the error is below a specified tolerance. Termination Criteria - specify the success condition as the difference between some quantity and its actual value is within a certain tolerance – 2 ways: absolute error - difference between the result and the actual value. relative error is the difference between the result and the actual value relative to the size of the result. Tolerance property - specify trade-off between accuracy and execution time. The lower the tolerance, the longer it will take for the algorithm to obtain a result within that tolerance. Most algorithms in the EO NumLib have a default value of MachineConstants.SqrtEpsilon - gives slightly less than 8 digits of accuracy. ConvergenceCriterion property - specify under what condition the algorithm is assumed to converge. Using the ConvergenceCriterion enum: WithinAbsoluteTolerance / WithinRelativeTolerance / WithinAnyTolerance / NumberOfIterations Active property - selectively ignore certain convergence tests Error property - returns the estimated error after a run MaxIterations / MaxEvaluations properties - Other Termination Criteria - If the algorithm cannot achieve the desired accuracy, the algorithm still has to end – according to an absolute boundary. Status property - indicates how the algorithm terminated - the AlgorithmStatus enum values:NoResult / Busy / Converged (ended normally - The desired accuracy has been achieved) / IterationLimitExceeded / EvaluationLimitExceeded / RoundOffError / BadFunction / Divergent / ConvergedToFalseSolution. After the iteration terminates, the Status should be inspected to verify that the algorithm terminated normally. Alternatively, you can set the ThrowExceptionOnFailure to true. Result property - returns the result of the algorithm. This property contains the best available estimate, even if the desired accuracy was not obtained. IterationsNeeded / EvaluationsNeeded properties - returns the number of iterations required to obtain the result, number of function evaluations.  Concrete Types of Convergence Test classes SimpleConvergenceTest class - test if a value is close to zero or very small compared to another value. VectorConvergenceTest class - test convergence of vectors. This class has two additional properties. The Norm property specifies which norm is to be used when calculating the size of the vector - the VectorConvergenceNorm enum values: EuclidianNorm / Maximum / SumOfAbsoluteValues. The ErrorMeasure property specifies how the error is to be measured – VectorConvergenceErrorMeasure enum values: Norm / Componentwise ConvergenceTestCollection class - represent a combination of tests. The Quantifier property is a ConvergenceTestQuantifier enum that specifies how the tests in the collection are to be combined: Any / All  The AlgorithmHelper Class inherits from IterativeAlgorithm<T> and exposes two methods for convergence testing. IsValueWithinTolerance<T> method - determines whether a value is close to another value to within an algorithm's requested tolerance. IsIntervalWithinTolerance<T> method - determines whether an interval is within an algorithm's requested tolerance.

  • 4 Alternatives to Google Drive for Linux

    - by Chris Hoffman
    We’ve covered using Google Drive on Linux with third-party software, but why bother jumping through those hoops? You can use a cloud storage service that officially supports Linux instead – several of Google Drive’s competitors do. Google may be leaving Linux users out, but other services like Dropbox, Ubuntu One, SpiderOak, and Wuala don’t ignore Linux users. They even offer more storage and other useful features, such as local encryption of your files.
