  • SQL Saturday Atlanta: Intro To Performance Tuning

    - by Mike Femenella
    I'm looking forward to speaking in Atlanta on the 24th, will be fun to get back down that way to visit with some friends and present two topics that I really enjoy. First, an introduction to performance tuning. Performance tuning is a very wide and deep topic and we're staying close to the surface. I direct this class for newbie sql users who have less than 2 years of experience. It's all the things I wish someone would have told me in my first 2 years about what to look for when the database was slow...or allegedly slow I should say. We'll cover using profiler to find slow performing queries and how to save the data off to a table as well as a tour of other features. The difference between clustered, non clustered and covering indexes. How to look at and understand an execution plan (at a high level) and finally the difference between a temp table and a table variable and what the implications are of using either one in your code. That pretty much takes up a full hour. Second presentation, Loading Data in Real Time. It's really a presentation about partitioning but with a twist that we used at work recently to solve a need to load some data quickly and put it into production with minimal downtime. We'll cover partition functions, schemes,$partition, merge, sys.partitions and show some examples of building a set of partitioned tables and using the switch statement to move it from one table to another. Finally we'll cover the differences in partitioning between 2005 and 2008. Hope to see you there! And if you read my blog please introduce yourself!

  • A Look Inside JSR 360 - CLDC 8

    - by Roger Brinkley
    If you didn't notice during JavaOne the Java Micro Edition took a major step forward in its consolidation with Java Standard Edition when JSR 360 was proposed to the JCP community. Over the last couple of years there has been a focus to move Java ME back in line with it's big brother Java SE. We see evidence of this in JCP itself which just recently merged the ME and SE/EE Executive Committees into a single Java Executive Committee. But just before that occurred JSR 360 was proposed and approved for development on October 29. So let's take a look at what changes are now being proposed. In a way JSR 360 is returning back to the original roots of Java ME when it was first introduced. It was indeed a subset of the JDK 4 language, but as Java progressed many of the language changes were not implemented in the Java ME. Back then the tradeoff was still a functionality, footprint trade off but the major market was feature phones. Today the market has changed and CLDC, while it will still target feature phones, will have it primary emphasis on embedded devices like wireless modules, smart meters, health care monitoring and other M2M devices. The major changes will come in three areas: language feature changes, library changes, and consolidating the Generic Connection Framework.  There have been three Java SE versions that have been implemented since JavaME was first developed so the language feature changes can be divided into changes that came in JDK 5 and those in JDK 7, which mostly consist of the project Coin changes. There were no language changes in JDK 6 but the changes from JDK 5 are: Assertions - Assertions enable you to test your assumptions about your program. For example, if you write a method that calculates the speed of a particle, you might assert that the calculated speed is less than the speed of light. In the example code below if the interval isn't between 0 and and 1,00 the an error of "Invalid value?" would be thrown. private void setInterval(int interval) { assert interval > 0 && interval <= 1000 : "Invalid value?" } Generics - Generics add stability to your code by making more of your bugs detectable at compile time. Code that uses generics has many benefits over non-generic code with: Stronger type checks at compile time. Elimination of casts. Enabling programming to implement generic algorithms. Enhanced for Loop - the enhanced for loop allows you to iterate through a collection without having to create an Iterator or without having to calculate beginning and end conditions for a counter variable. The enhanced for loop is the easiest of the new features to immediately incorporate in your code. In this tip you will see how the enhanced for loop replaces more traditional ways of sequentially accessing elements in a collection. void processList(Vector<string> list) { for (String item : list) { ... Autoboxing/Unboxing - This facility eliminates the drudgery of manual conversion between primitive types, such as int and wrapper types, such as Integer.  Hashtable<Integer, string=""> data = new Hashtable<>(); void add(int id, String value) { data.put(id, value); } Enumeration - Prior to JDK 5 enumerations were not typesafe, had no namespace, were brittle because they were compile time constants, and provided no informative print values. JDK 5 added support for enumerated types as a full-fledged class (dubbed an enum type). In addition to solving all the problems mentioned above, it allows you to add arbitrary methods and fields to an enum type, to implement arbitrary interfaces, and more. Enum types provide high-quality implementations of all the Object methods. They are Comparable and Serializable, and the serial form is designed to withstand arbitrary changes in the enum type. enum Season {WINTER, SPRING, SUMMER, FALL}; } private Season season; void setSeason(Season newSeason) { season = newSeason; } Varargs - Varargs eliminates the need for manually boxing up argument lists into an array when invoking methods that accept variable-length argument lists. The three periods after the final parameter's type indicate that the final argument may be passed as an array or as a sequence of arguments. Varargs can be used only in the final argument position. void warning(String format, String... parameters) { .. for(String p : parameters) { ...process(p);... } ... } Static Imports -The static import construct allows unqualified access to static members without inheriting from the type containing the static members. Instead, the program imports the members either individually or en masse. Once the static members have been imported, they may be used without qualification. The static import declaration is analogous to the normal import declaration. Where the normal import declaration imports classes from packages, allowing them to be used without package qualification, the static import declaration imports static members from classes, allowing them to be used without class qualification. import static data.Constants.RATIO; ... double r = Math.cos(RATIO * theta); Annotations - Annotations provide data about a program that is not part of the program itself. They have no direct effect on the operation of the code they annotate. There are a number of uses for annotations including information for the compiler, compiler-time and deployment-time processing, and run-time processing. They can be applied to a program's declarations of classes, fields, methods, and other program elements. @Deprecated public void clear(); The language changes from JDK 7 are little more familiar as they are mostly the changes from Project Coin: String in switch - Hey it only took us 18 years but the String class can be used in the expression of a switch statement. Fortunately for us it won't take that long for JavaME to adopt it. switch (arg) { case "-data": ... case "-out": ... Binary integral literals and underscores in numeric literals - Largely for readability, the integral types (byte, short, int, and long) can also be expressed using the binary number system. and any number of underscore characters (_) can appear anywhere between digits in a numerical literal. byte flags = 0b01001111; long mask = 0xfff0_ff08_4fff_0fffl; Multi-catch and more precise rethrow - A single catch block can handle more than one type of exception. In addition, the compiler performs more precise analysis of rethrown exceptions than earlier releases of Java SE. This enables you to specify more specific exception types in the throws clause of a method declaration. catch (IOException | InterruptedException ex) { logger.log(ex); throw ex; } Type Inference for Generic Instance Creation - Otherwise known as the diamond operator, the type arguments required to invoke the constructor of a generic class can be replaced with an empty set of type parameters (<>) as long as the compiler can infer the type arguments from the context.  map = new Hashtable<>(); Try-with-resource statement - The try-with-resources statement is a try statement that declares one or more resources. A resource is an object that must be closed after the program is finished with it. The try-with-resources statement ensures that each resource is closed at the end of the statement.  try (DataInputStream is = new DataInputStream(...)) { return is.readDouble(); } Simplified varargs method invocation - The Java compiler generates a warning at the declaration site of a varargs method or constructor with a non-reifiable varargs formal parameter. Java SE 7 introduced a compiler option -Xlint:varargs and the annotations @SafeVarargs and @SuppressWarnings({"unchecked", "varargs"}) to supress these warnings. On the library side there are new features that will be added to satisfy the language requirements above and some to improve the currently available set of APIs.  The library changes include: Collections update - New Collection, List, Set and Map, Iterable and Iteratator as well as implementations including Hashtable and Vector. Most of the work is too support generics String - New StringBuilder and CharSequence as well as a Stirng formatter. The javac compiler  now uses the the StringBuilder instead of String Buffer. Since StringBuilder is synchronized there is a performance increase which has necessitated the wahat String constructor works. Comparable interface - The comparable interface works with Collections, making it easier to reuse. Try with resources - Closeable and AutoCloseable Annotations - While support for Annotations is provided it will only be a compile time support. SuppressWarnings, Deprecated, Override NIO - There is a subset of NIO Buffer that have been in use on the of the graphics packages and needs to be pulled in and also support for NIO File IO subset. Platform extensibility via Service Providers (ServiceLoader) - ServiceLoader interface dos late bindings of interface to existing implementations. It helpe to package an interface and behavior of the implementation at a later point in time.Provider classes must have a zero-argument constructor so that they can be instantiated during loading. They are located and instantiated on demand and are identified via a provider-configuration file in the METAINF/services resource directory. This is a mechansim from Java SE. import com.XYZ.ServiceA; ServiceLoader<ServiceA> sl1= new ServiceLoader(ServiceA.class); Resources: META-INF/services/com.XYZ.ServiceA: ServiceAProvider1 ServiceAProvider2 ServiceAProvider3 META-INF/services/ServiceB: ServiceBProvider1 ServiceBProvider2 From JSR - I would rather use this list I think The Generic Connection Framework (GCF) was previously specified in a number of different JSRs including CLDC, MIDP, CDC 1.2, and JSR 197. JSR 360 represents a rare opportunity to consolidated and reintegrate parts that were duplicated in other specifications into a single specification, upgrade the APIs as well provide new functionality. The proposal is to specify a combined GCF specification that can be used with Java ME or Java SE and be backwards compatible with previous implementations. Because of size limitations as well as the complexity of the some features like InvokeDynamic and Unicode 6 will not be included. Additionally, any language or library changes in JDK 8 will be not be included. On the upside, with all the changes being made, backwards compatibility will still be maintained. JSR 360 is a major step forward for Java ME in terms of platform modernization, language alignment, and embedded support. If you're interested in following the progress of this JSR see the JSR's java.net project for details of the email lists, discussions groups.

  • Version control for game development - issues and solutions?

    - by Cyclops
    There are a lot of Version Control systems available, including open-source ones such as Subversion, Git, and Mercurial, plus commercial ones such as Perforce. How well do they support the process of game-development? What are the issues using VCS, with regard to non-text files (binary files), large projects, etc? What are solutions to these problems, if any? For organization of Answers, let's try on a per-package basis. Update each package/Answer with your results. Also, please list some brief details in your answer, about whether your VCS is free or commercial, distributed versus centralized, etc. Update: Found a nice article comparing two of the VCS below - apparently, Git is MacGyver and Mercurial is Bond. Well, I'm glad that's settled... And the author has a nice quote at the end: It’s OK to proselytize to those who have not switched to a distributed VCS yet, but trying to convert a Git user to Mercurial (or vice-versa) is a waste of everyone’s time and energy. Especially since Git and Mercurial's real enemy is Subversion. Dang, it's a code-eat-code world out there in FOSS-land...

  • Force Blank TextBox with ASP.Net MVC Html.TextBox

    - by Doug Lampe
    I recently ran into a problem with the following scenario: I have data with a parent/child data with a one-to-many relationship from the parent to the child. I want to be able to update parent and existing child data AND add a new child record all in a single post. I don't want to create a model just to store the new values. One of the things I LOVE about MVC is how flexible it is in dealing with posted data.  If you have data that isn't in your model, you can simply use the non-strongly-typed HTML helper extensions and pass the data into your actions as parameters or use the FormCollection.  I thought this would give me the solution I was looking for.  I simply used Html.TextBox("NewChildKey") and Html.TextBox("NewChildValue") and added parameters to my action to take the new values.  So here is what my action looked like: [HttpPost] public ActionResult EditParent(int? id, string newChildKey, string newChildValue, FormCollection forms) {     Model model = ModelDataHelper.GetModel(id ?? 0);     if (model != null)     {         if (TryUpdateModel(model))         {             if (ModelState.IsValid)             {                 model = ModelDataHelper.UpdateModel(model);             }             string[] keys = forms.GetValues("ChildKey");             string[] values = forms.GetValues("ChildValue");             ModelDataHelper.UpdateChildData(id ?? 0, keys, values);             ModelDataHelper.AddChildData(id ?? 0, newChildKey, newChildValue);             model = ModelDataHelper.GetModel(id ?? 0);         }        return View(report);     }    return new EmptyResult(); } The only problem with this is that MVC is TOO smart.  Even though I am not using a model to store the new child values, MVC still passes the values back to the text boxes via the model state.  The fix for this is simple but not necessarily obvious, simply remove the data from the model state before returning the view: ModelState.Remove("NewChildKey"); ModelState.Remove("NewChildValue"); Two lines of code to save a lot of headaches.

  • Is there a portal dedicated to HTML5 games?

    - by Bane
    Just to get something straight; by "portal", I mean a website that frequently publishes a certain type of games, has a blog, some articles, maybe some tutorials and so on. All of these things are not required (except the game publishing part, of course), for example, I consider Miniclip to be a flash game portal. The reason for defining this term is because I'm not sure if other people use it in this context. I recently (less than a year ago) got into HTML5 game development, nothing serious, just my own small projects that I didn't really show to a lot of people, and that certainly didn't end up somewhere on the web (although, I am planning to make a website for my next game). I am interested in the existence of an online portal where indie devs (or non-indie ones, doesn't really matter that much) can publish their own games, sort of like "by devs for devs", also a place where you can find some simple tutorials on basic HTML5 game development and so on... I doubt something like this exists for several reasons: You can't really commercialize an HTML5 game without a strong server-side and microtransactions The code can be easily copied HTML5 is simply new, and things need time to get their own portals somewhere... If a thing like this does not exist, I think I might get into making one some day...

  • Oracle Delivers Special Recognition for Specialized Partners

    - by michaela.seika(at)oracle.com
    Since announcing Oracle PartnerNetwork Specialized (OPN Specialized) in October 2009, Oracle has been focused on building a program that first enables solution providers to become highly skilled Oracle partners who deliver value to customers and that then recognizes and rewards their achievements in a meaningful way. Today the company unveiled new benefits reserved for partners who have achieved one or more of the over 50 specializations currently available. The benefits demonstrate Oracle's commitment to showcase these valued partners to three key audiences: customers, other partners, and Oracle employees.With today's launch of www.oracle.com/specialized Oracle has taken what IDC believes is a first of its kind approach to putting top partners front and center with customers and prospects. While most vendors offer a business partner finder tool on their website none has gone as far as Oracle with the creation of this new site dedicated to the promotion of Specialized Partners. The tag lines - "Recognized by Oracle, Preferred by Customers" and "Specialized. Recognized. Preferred." gets right to the point - these are the solution providers with which customers should choose to engage. The contents of the page offer multiple proof points to justify the marketing phrases.One of the benefits Oracle offers its Specialized Partners is video creation and placement. While Oracle works with partners to create informal or "guerilla" videos which often are placed on YouTube to generate awareness and buzz, the company also produces professional videos for its partners. The greatest value the partner receives from this benefit isn't the non-trivial production costs that Oracle covers but instead the prominent exposure Oracle gives the finished product. Partner videos are featured on www.oracle.com/specialized, used as part of monthly OPN Specialized Partners monthly webcasts, placed on a customer facing website, the Oracle Media Network, which includes several partner sites such as PartnerCast. A solution provider gains a great deal of credibility when they can send a prospect to an Oracle website where they are featured. Read the full article here.

  • Are very short or abbreviated method/function names that don't use full words bad practice or a matter of style.

    - by Alb
    Is there nowadays any case for brevity over clarity with method names? Tonight I came across the Python method repr() which seems like a bad name for a method to me. It's not an English word. It apparently is an abbreviation of 'representation' and even if you can deduce that, it still doesn't tell you what the method does. A good method name is subjective to a certain degree, but I had assumed that modern best practices agreed that names should be at least full words and descriptive enough to reveal enough about the method that you would easily find one when looking for it. Method names made from words help let your code read like English. repr() seems to have no advantages as a name other than being short and IDE auto-complete makes this a non-issue. An additional reason given in an answer is that python names are brief so that you can do many things on one line. Surely the better way is to just extract the many things to their own function, and repeat until lines are not too long. Are these just a hangover from the unix way of doing things? Commands with names like ls, rm, ps and du (if you could call those names) were hard to find and hard to remember. I know that the everyday usage of commands such as these is different than methods in code so the matter of whether those are bad names is a different matter.

  • general questions about link spam

    - by hen3ry
    Hello, A CMS-based site I manage is suffering from a small but ominously growing number of almost certainly bot-emplaced, invisible spam links placed in registered-user-only shoutboxes and user forums. "Link Spam", yes? Until recently, I've kept my eyes on narrow tech issues, and I'm having trouble understanding what's going on. I understand that we need to tighten up our registration procedures, but more generally... Do I understand correctly that our primary interest in combatting link spam on our site is that major search engines reduce or zero the search visibility of sites that contain link spam? Although we're non-commercial, we don't want to be at the bottom of the rankings, or eliminated altogether. Are the linked-to sites the direct beneficiaries of the spam links, or is there some kind of indirection? What is the likely relationship between the link-spammers and the owners of the (directly or indirectly) linked-to sites? Are the owners of the linked-to sites paying the link-spammers for higher visibility? Are the owners aware that this method is being used? It is my impression that major search engines are capable these days of detecting that given sites are being promoted by link spam, and that these sites may consequently be reduced in search rank or dropped altogether. Do these sanctions occur frequently? Is there any potential value in sending notifications to the owners of the linked-to sites that their visibility is at risk? TIA, hen3ry

  • Unable to mount smb share. "Please select another viewer and try again". Please help. Serious smb/nautilus foo needed

    - by oznah
    This don't think this is the typical, "I can't mount a windows share" post. I am using stock Ubuntu 12.04. I am pretty sure this is a Nautilus issue, but I have reached a dead end. I have one share that I can't mount using smb://server/share via nautilus. I get the following error. Error: Failed to mount Windows share Please select another viewer and try again I can mount this share from other machines(non-ubuntu) using the same credentials so I know I have perms on the destination share. I can mount other shares on other servers from my Ubuntu box so I am pretty sure I have all the smb packages I need on my Ubuntu box. To make thing more interesting, if I use smbclient from the command line, I mount this share with no problems from my Ubuntu box. So here's what we know: destination share perms are ok (no problem accessing from other machines) smb is setup correctly on Ubuntu box (access other windows shares no problem) I only get the error when using nautilus smbclient in terminal works, no problem Any help would be greatly appreciated. Googling turned up simple mount/perms issues, and I don't think that is what is going on here. Let me know if you need more information. Hugh

    Steam says I'm missing the following libs, I'm hoping someone can help me get things in better shape: xyz@abc:~$ STEAM_RUNTIME=0 steam Running Steam on ubuntu 14.04 64-bit STEAM_RUNTIME is disabled by the user Error: You are missing the following 32-bit libraries, and Steam may not run: libpangoft2-1.0.so.0 libpango-1.0.so.0 libgtk-x11-2.0.so.0 libgdk_pixbuf-2.0.so.0 Installing breakpad exception handler for appid(steam)/version(1401381906_client) Installing breakpad exception handler for appid(steam)/version(1401381906_client) [2014-06-11 20:45:39] Startup - updater built May 29 2014 09:19:23 [2014-06-11 20:45:39] Verifying installation... [2014-06-11 20:45:39] Verification complete [2014-06-11 20:45:42] Shutdown I tried installing the following i386 packages: libpango-1.0-0:i386, libpangoft2-1.0-0:i386, and libgdk-pixbuf2.0-0:i386, and symlinking the .so files (from usr/lib/i386whatever../) into the ~/.local/share/Steam/ubuntu12_32/ folder, but wasn't able to find the right match for the gtk-x11 lib, and ultimately would up with a different, but still non-working situation. So I've back-tracked to this point, and have removed those i386 packages for now. It's worth noting thatSteam runs if I don't use STEAM_RUNTIME=0. Also, Steam seemed to "recognize" the i386 version of the libpango & libpangoft2 libs after I symlinked them into place, during the course of my troubleshooting; when I would rerun STEAM_RUNTIME=0 steam, it wouldn't list those two items as missing anymore. Instead though, I had a bunch of gtk-related issues, something about overlay-scrollbar not available, as well as warnings that it can't find the murrine engine... a whole bunch of stuff that sounded like I'd gone too far down the wrong path. Anyhow, any help sorting this out would be appreciated, and thanks!

  • Self hosted PHP shopping cart with no storefront?

    - by Question
    I am looking for a shopping cart to implement on a simple website instead of the default paypal cart that is used with their add to cart buttons (I don't like the non-styeable new tab/window cart). However, I really like the ability to simply add the buttons to existing pages. I do not have a lot of products and do not want to deal with a storefront and complex templates. The main features I need: Self-hosted Easy to implement with existing website (copy and paste button code, etc.) Ability to have variations on one button with different prices (dropdown with sizes, colors, etc.) Ability to track inventory and disallow out of stock orders Ability to pass cart details to PayPal Website Payments Standard I have seen most of the large storefront options: oscommerce, zencart, cubecart, opencart, prestashop, magento, cs-cart, lemonstand, etc. but these are way more than I need. I don't need the storefront or customer accounts or templated pages, etc. I have seen e-junkie, which is not far off from what I would like, but it is not self-hosted and I would prefer an in-site cart (or dynamic overlay cart) rather than a lightbox or new tab/window cart. I also love the paypal minicart and its implementation, but there is no way to track inventory. So, does anyone have any recommendations that might meet these requests?

  • Versioning and Continuous Integration with project settings files

    - by Michael Stephenson
    I came across something which was a bit of a pain in the bottom the other week. Our scenario was that we had implemented a helper style assembly which had some custom configuration implemented through the project settings. I'm sure most of you are familiar with this where you end up with a settings file which is viewable through the C# project file and you can configure some basic settings. The settings are embedded in the assembly during compilation to be part of a DefaultValue attribute. You have the ability to override the settings by adding information to your app.config and if the app.config doesn’t override the settings then the embedded default is used. All normal C# stuff so far… Where our pain started was when we implement Continuous Integration and we wanted to version all of this from our build. What I was finding was that the assembly was versioned fine but the embedded default value was maintaining the non CI build version number. I ended up getting this to work by using a build task to change the version numbers in the following files: App.config Settings.settings Settings.designer.cs I think I probably could have got away with just the settings.designer.cs, but wanted to keep them all consistent incase we had to look at the code on the build server for some reason. I think the reason this was painful was because the settings.designer.cs is only updated through Visual Studio and it writes out the code to this file including the DefaultValue attribute when the project is saved rather than as part of the compilation process. The compile just compiles the already existing C# file. As I said we got it working, and it was a bit of a pain. If anyone has a better solution for this I'd love to hear it

  • mdadm: breaks boot due to "is not ready yet or not present" error

    - by BarsMonster
    This is so damn frustrating :-| I've spent like 20 hours on this nice error, and seems like dozens of people over Internet too, and no clear solution yet. I have non-system RAID-5 of 5 disks, and it's fine. But during boot up it says that "/dev/md0 is not ready yet or not present" and asks to press 'S'. Very nice for Ubuntu Server - I have to bring monitor and keyboard to go next. After this system boots and it's all fine. md0 device works, /proc/mdstat is fine. When I do mount -a - it mounts this array without errors and works fine. As a dumb and shameful workaround I added noauto in /etc/fstab, and did mounting in /etc/rc.local - it works fine then. Any hints how to make it work properly? fstab: UUID=3588dfed-47ae-4c32-9855-2d69df713b86 /var/bigfatdisk ext4 noauto,noatime,data=writeback,barrier=0,nobh,commit=5 0 0 mdadm config: It is autogenerated: # mdadm.conf # # Please refer to mdadm.conf(5) for information about this file. # # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired.

  • CUOA Workshop: “L’evoluzione dei modelli e dei sistemi di analisi e reporting direzionale”

    - by Paolo Leveghi
    Il 26 Giugno scorso presso l’Aula Magna della Fondazione CUOA si è tentuo il workshop “L’evoluzione dei modelli e dei sistemi di analisi e reporting direzionale”, promosso dal Club Finance CUOA con la collaborazione di Oracle .  Una recente analisi di Gartner ha evidenziato che Executives Finance ed IT hanno identificato Business Intelligence, Analytics e Performance Management come tema prioritario su cui concentrare gli investimenti “tecnologici” nel 2013 confermando, se mai qualcuno ne avesse avuto bisogno, la continua e crescente attenzione delle aziende alla propria capacità di definire, produrre e gestire informazioni funzionali all’identificazione di opportunità, alla valutazione di rischi ed impatti, alla simulazione degli effetti di operazioni ordinarie e straordinarie...in un solo concetto, informazioni funzionali alla guida dell’azienda. Questo dato è ancora più interessante se incrociato con il risultato di una survey condotta da CFO Magazine e KPMG International nella quale il 48% dei CFO intervistati ha dichiarato di ritenere i propri sistemi datati ed poco flessibili, quindi un limite, se non proprio un freno, alla loro volontà di essere agenti del cambiamento. A fronte di tutto questo, le aziende dimostrano un crescente interesse a capire cosa fare, oggi e domani, per migliorare la propria capacità di sfruttare una risorsa aziendale estremamente pregiata quale l’informazione. L’    Obiettivo del workshop è quindi stato quello di analizzare in quale scenario stanno operando oggi le aziende del Nord Est Italiano verificando, grazie alle testimonianze di ITAL TBS e del Gruppo Carraro,  lo “stato di salute” dei processi di Business Analytics, il livello di cultura aziendale ed il grado di adozione di soluzioni da parte dei CFO, del Management e più in generale dei decisori aziendali, i percorsi evolutivi e prospettici per migliorare su questi temi

  • General questions regarding open-source licensing

    - by ndg
    I'm looking to release an open-source iOS software project but I'm very new to the licensing side of the things. While I'm aware that the majority of answers here will not lawyers, I'd appreciate it if anyone could steer me in the right direction. With the exception of the following requirements I'm happy for developers to largely do whatever they want with the projects source code. I'm not interested in any copyleft licensing schemes, and while I'd like to encourage attribution in derivative works it is not required. As such, my requirements are as follows: Original source can be distributed and re-distributed (verbatim) both commercially and non-commercially as long as the original copyright information, website link and license is maintained. I wish to retain rights to any of the multi-media distributed as part of the project (sound effects, graphics, logo marks, etc). Such assets will be included to allow other developers to easily execute the project, but cannot be re-distributed in any manner. I wish to retain rights to the applications name and branding. Futher to selecting an applicable license, I have the following questions: The project makes use of a number of third-party libraries (all licensed under variants of the MIT license). I've included individual licenses within the source (and application) and believe I've met all requirements expressed in these licenses, but is there anything else that needs to be done before distributing them as part of my open-source project? Also included in my project is a single proprietary, close-sourced library that's used to power a small part of the application. I'm obviously unable to include this in the source release, but what's the best way of handling this? Should I simply weak-link the project and exclude it entirely from the Git project?

  • Form Validation Options

    The steps involved in transmitting form data from the client to the Web server User loads web form. User enters data in to web form fields User clicks submit On submit page validates fields using JavaScript. If validation errors are found then the validation script stops the browser from canceling posting the data to the web server and displays error messages as needed. If the form passes the data validation process then the browser will URL encode the values of every field and post it to the server.  The server reads the posted data from the query string and then again validates the data just to ensure data consistency and to prevent any non-validated data because JavaScript was turned off on the clients browser from being inserted in to a database or passed on to other process. If the data passes the second validation check then the server side code will continue with the requested processes. In my opinion, it is mandatory to validate data using client side and server side validation as a fail over process. The client side validation allows users to correct any error before they are sent to the web server for processing, and this allows for an immediate response back to the user regarding data that is not correct or in the proper format that is desired. In addition, this prevents unnecessary interaction between the user and the web server and will free up the server over time compared to doing only server side validation. Server validation is the last line of defense when it comes to validation because you can check to ensure the user’s data is correct before it is used in a business process or stored to a database. Honestly, I cannot foresee a scenario where I would only want to use one form of validation over another especially with the current cost of creating and maintaining data. In my opinion, the redundant validation is well worth the overhead.

  • What web technology could I use which would support a decision tree?

    - by Rami Alhamad
    I am a big game development fan but I haven't done any commercial work in the past. I have been asked by a non-profit to look at developing a game similar to the award-winning www.playspent.org They want the following features: support 5 scenarios mobile isn't important but compatibility with older browsers would be a big bonus they want it to be visual and audible bonus is to have it easily modifiable support 4 languages I don't have much knowledge of Flash and would rather avoid using it as a solution. I started breaking down the problem into segments that I will need to examine, they are as follows: ability to read the game flow from a file that they can produce (xml, etc.) db design to store decision tree language challenge browser compatibility I am leaning towards an Google app engine/GWT solution but I am not sure what technology is best for this. I am really hoping to get your opinion/recommendation on my approach and on what technology is best. A special thanks (and beer if you live in Toronto) will be awarded to anyone who can help give me a ballpark estimate on how much such a game should go for. I know it's tough to estimate but any rough figure will help (how much would you charge for building something like playspent.org?) Thanks in advance

  • RTFMobile

    - by ultan o'broin
    It may seem obvious but it’s worth stating again. The idea that mobile users are going to read lots of user assistance on their devices is just wrong. So, Jakob Nielsen’s post Mobile Content Is Twice as Difficult serves as a timely reminder for anyone thinking of putting manuals as a form of user assistance onto mobile phones. There is also an excellent post on UXMag.com, explaining that one of the ways to screw up with your iPhone app is to throw an old-style user manual into the user experience: 10 Surefire Ways to Screw Up Your iPhone App.   (Image copyright and referenced from UX Magazine 2010)   Instead, user assistance  alternatives—if any at all—include one-time tours, graphics, in-context instructions, and so on. Not so sure that importing “humor” and “personality” work so well in the enterprise app space, myself. However, the message is clear: iPhone users don’t read manuals. Great message. Users will figure it out, and if they can’t, well then your app’s UX is a problem and the app will fail. Shame some teams are obsessed with figuring out ways to port existing manuals to mobile platforms without any thought for the UX. Razorfish’s Scatter/Gather blog says it all: One thing that is particularly discouraging, most material currently available on “Creating Content for the iPad” or similar themes turns out to be about getting traditional content onto, or into, the iPad. Now, manuals for non-end users in PDF format on eReaders is a different matter. I have research on that, but it’s for another post.

  • installing ubuntu on SSD

    - by kunal
    Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

  • How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

    - by András Szepesházi
    If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical.

  • The JavaServer Faces 2.2 viewAction Component

    - by Janice J. Heiss
    Life just got easier for users of JavaServer Faces. In a new article, now up on otn/java, titled “New JavaServer Faces 2.2 Feature: The viewAction Component,” Tom McGinn, Oracle’s Principal Curriculum Developer for Oracle Server Technologies, explores the advantages offered by the JavaServer Faces 2.2 view action feature, which, according to McGinn, “simplifies the process for performing conditional checks on initial and postback requests, enables control over which phase of the lifecycle an action is performed in, and enables both implicit and declarative navigation.”As McGinn observes: “A view action operates like a button command (UICommand) component. By default, it is executed during the Invoke Application phase in response to an initial request. However, as you'll see, view actions can be invoked during any phase of the lifecycle and, optionally, during postback, making view actions well suited to performing preview checks.”McGinn explains that the JavaServer Faces 2.2 view action feature offers several advantages over the previous method of performing evaluations before a page is rendered:   * View actions can be triggered early on, before a full component tree is built, resulting in a lighter weight call.   * View action timing can be controlled.   * View actions can be used in the same context as the GET request.   * View actions support both implicit and explicit navigation.   * View actions support both non-faces (initial) and faces (postback) requests.Read the complete article here.

  • Marshalling the value of a char* ANSI string DLL API parameter into a C# string

    - by Brian Biales
    For those who do not mix .NET C# code with legacy DLL's that use char* pointers on a regular basis, the process to convert the strings one way or the other is non-obvious. This is not a comprehensive article on the topic at all, but rather an example of something that took me some time to go find, maybe it will save someone else the time. I am utilizing a third party too that uses a call back function to inform my application of its progress.  This callback includes a pointer that under some circumstances is a pointer to an ANSI character string.  I just need to marshal it into a C# string variable.  Seems pretty simple, yes?  Well, it is, (as are most things, once you know how to do them). The parameter of my callback function is of type IntPtr, which implies it is an integer representation of a pointer.  If I know the pointer is pointing to a simple ANSI string, here is a simple static method to copy it to a C# string: private static string GetStringFromCharStar(IntPtr ptr) {     return System.Runtime.InteropServices.Marshal.PtrToStringAnsi(ptr); } The System.Runtime.InteropServices is where to look any time you are mixing legacy unmanaged code with your .NET application.

  • DotNetNuke + PayPal

    - by Nuri Halperin
    A DotNetNuke i'm supporting has had a paypal "buy now" button and other variations with custom fields for a while now. About 2 weeks ago (somewhere in March 2010) they all stopped working. The problem manifested such that once you clicked the "buy now" button, Paypal site would throw a scary error page to the effect of: "Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log" Once I verified no cheeky content editor changed the page, I went digging for answers. The main source incompatibility of PayPal's simple HTML forms is that DNN includes a form on every page, and nested forms are not really supported. As blogged here and lamented here, the solution I came up with is simply to modify the form enctype to 'application/x-www-form-urlencoded' as illustrated below: 1: <input type="image" border="0" 2: src="https://www.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" 3: name="submit" 4: alt="PayPal - The safer, easier way to pay online!" 5: onClick="this.form.action='https://www.paypal.com/cgi-bin/webscr'; this.form.enctype='application/x-www-form-urlencoded';this.form.submit();" /> One would think that PayPal would want the masses submitting HTML in all manners of "enctype", but I guess every company has it's quirks. At least my favorite non-profit can now continue and accept payments. Sigh.
