• Mohsen Agsen on C++

  - by raccoon_tim

  As I already blogged a while back, native code has been on the lips of many since TechEd 2011. Microsoft seems very committed to actually putting the language to use again after all these years of radio silence. Regarding this I urge you all guys to watch this video interview of Mohsen Agsen about C++ Today and Tomorrow http://channel9.msdn.com/Shows/Going+Deep/Mohsen-Agsen-C-Today-and-Tomorrow on Channel 9. What I find very inspiring about this interview is that Microsoft has a number of internal projects where they are using C++ and they really understand the value of C++ as a highly performant programming language. He also talks about combining managed code, scripted code and native code to get the most out of each of them. This is something that we are doing a lot in the game industry, since we recognize the need for performant platform code with an easy to write scripting layer on top of that. This is something I intend to blog about in the near future, so stay tuned! Another great thing that I bumped into recently is C++ AMP that was announced at this year’s AMD Fusion Developer Summit. I would recommend watching Herb Sutter’s keynote on the subject at http://channel9.msdn.com/posts/AFDS-Keynote-Herb-Sutter-Heterogeneous-Computing-and-C-AMP.

• AsyncBridge? Async on .NET 4.0 using VS11

  - by Alex.Davies

  I've just found something quite cool. It's a code snippet that lets you use the real VS 11 C#5 compiler to write code that uses the async and await keywords, but to target .NET 4.0. It was published by Daniel Grunwald (from SharpDevelop).That means I can stop using the Async CTP for VS2010, which is not at all supported anymore, and a pain to install if you have windows updates turned on. Obviously I couldn't ask all my users to install .NET 4.5 beta, but .NET Demon is a VS 2010 extension, so we already have .NET 4.0. At the time of writing, VS11 is in beta still, but hopefully it's stable enough for my team to use!I would have written the code myself, but I had the wrong impression that the C# 5 beta compiler only looked in mscorlib for the helper classes it needs to implement async methods. Turns out you can provide them yourself. You can get the code here: https://gist.github.com/1961087You just add it to your project, and the compiler will apparently pick it up and use it to implement async/await. I'm at my parents' place for Easter without access to a machine with VS 11 to try it out. Let me know whether you get it to work!This reminds me of LINQBridge, which let us use C# 3 LINQ, but only require .NET 2. We should stick up a webpage to explain, with a nice easy dll, put it in nuget, and call it AsyncBridge.If you were really enthusiastic, you could re-implement the skeleton of the Task Parallel Library against .NET 2 to use async/await without even requiring .NET 4. Our usage stats suggest that practically everyone that uses Red Gate tools already has .NET 4 installed though, so I don't think I'll go to the effort.

• Script Task/Component and Template Information

  The Script Task and Script component are often used by people developing SSIS packages because they are easy to use and now because SSIS could be perceived to be more developer friendly they are very powerful. That being said we should no be using them everywhere.  There are generally Tasks/Components already provided that will do the job it may be that we have to rethink the way we want to draw our package. I had cause last week to break out the script component in SQL Server 2008 SP1 and found that it was broken.  I don’t know when it broke as I do not use them all that often.  My error was as below.     Something must have overwritten this template information.  I looked in Event Viewer and tried the things it suggested but the templates still did not work.  Here is how I got them eventually to work for me (Your Mileage may vary) Open up a Command Prompt window using an administrator level account and “as an administrator” vsta.exe /hostid SSIS_ScriptTask /setup vsta.exe /hostid SSIS_ScriptComponent /setup   This worked for me.  Hope it helps.

• How to edit and enlarge the font in a PDF document? [closed]

  - by Gus

  Possible Duplicate: How to enlarge a PDF document on Kindle? I have a kindle 6". The problem is that I often read pdf files that are technical, therefore, it doesn't get converted very well to Kindle's native format (for example, code blocks get messed, and things like that). When I watch the pdf page, it's very small to read easily, so I have to rotate the screen to a horizontal position in order to see it better, but my page get divided. But some documents would be easy to read in vertical position if I had the chance to enlarge the font size a little bit in a external pdf editor, therefore enabling the reading in the vertical orientation. Is there a way to change the font size in a pdf file?

• How to automatically show USB camera or memory stick contents in Icewm?

  - by darenw

  I normally use a very lightweight Linux setup. No desktop like Gnome or KDE, just Icewm as the windows manager and nothing else that normal users might consider essential. Well, I do need a file manager - I use Thunar. Recently I've been trying Gnome. Whenever I shove a memory stick into a USB port, or connect my digital camera, it can automatically pop up a file manager showing all the goodies on that device. KDE does this too. I like this. Although quick at the command line, I like not having to go sudo to mount the device and all that. If I want to stick with a lightweight setup using Icewm+Thunar, is there something non-huge I can install to make external devices fire up a Thunar window, or otherwise make access to the contents brainlessly easy?

• Does this syntax for specifying Django conditional form display align with python/django convention?

  - by andy

  I asked a similar question on Stackoverflow and was told it was better asked here. So I'll ask it slightly rephrased. I am working on a Django project, part of which will become a distributable plugin that allows the python/django developer to specify conditional form field display logic in the form class or model class. I am trying to decide how the developer must specify that logic. Here's an example: class MyModel(models.Model): #these are some django model fields which will be used in a form yes_or_no = models.SomeField...choices are yes or no... why = models.SomeField...text, but only relevant if yes_or_no == yes... elaborate_even_more = models.SomeField...more text, just here so we can have multiple conditions #here i am inventing some syntax...i am looking for suggestions!! #this is one possibility why.show_if = ('yes_or_no','==','yes') elaborate_even_more.show_if = (('yes_or_no','==','yes'),('why','is not','None')) #help me choose a syntax that is *easy*...and Pythonic and...Djangonic...and that makes your fingers happy to type! #another alternative... conditions = {'why': ('yes_or_no','==','yes'), 'elaborate_even_more': (('yes_or_no','==','yes'),('why','is not','None')) } #or another alternative... """Showe the field whiche hath the name *why* only under that circumstance in whiche the field whiche hath the name *yes_or_no* hath the value *yes*, in strictest equality.""" etc... Those conditions will be eventually passed via django templates to some javascript that will show or hide form fields accordingly. Which of those options (or please propose a better option) aligns better with conventions such that it will be easiest for the python/django developer to use? Also are there other considerations that should impact what syntax I choose?

• How do you manage a complexity jump?

  - by glenatron

  It seems an infrequent but common experience that sometimes you're working on a project and suddenly something turns up unexpectedly, throws a massive spanner in the works and ramps up the complexity a whole lot. For example, I was working on an application that talked to SOAP services on various other machines. I whipped up a prototype that worked fine, then went on to develop a regular front end and generally get everything up and running in a nice, fairly simple and easy to follow fashion. It worked great until we started testing across a wider network and suddenly pages started timing out as the latency of the connections and the time required to perform calculations on remote machines resulted in timed out requests to the soap services. It turned out that we needed to change the architecture to spin requests out onto their own threads and cache the returned data so it could be updated progressively in the background rather than performing calculations on a request by request basis. The details of that scenario are not too important - indeed it's not a great example as it was quite forseeable and people who have written a lot of apps of this type for this type of environment might have anticipated it - except that it illustrates a way that one can start with a simple premise and model and suddenly have an escalation of complexity well into the development of the project. What strategies do you have for dealing with these types of functional changes whose need arises - often as a result of environmental factors rather than specification change - later on in the development process or as a result of testing? How do you balance between avoiding the premature optimisation/ YAGNI/ overengineering risks of designing a solution that mitigates against possible but not necessarily probable issues as opposed to developing a simpler and easier solution that is likely to be as effective but doesn't incorporate preparedness for every possible eventuality?

• First Experience with Web Services

  When I first started programming with Microsoft .Net (1.0 Framework) I had a strong desire to learn how search engines indexed web sites. At that time I was a working as a search engine spammer creating web pages to generate traffic for specific themes for various clients. One way I attempted to better understand .Net was to build a web spider that analyzed web pages on demand. An example of the spider is hosted at AddLinkz.com. After my spider was built I had no real idea what I could/should do with it until I found the MSN Search API. I used this web service to compare its results with my spider. Additionally, I used the API to feed my .Net web spider new URLs from the API based on specific search terms. MSN’s search API was very easy to use, I just had to request information by calling a web URL with parameters via a Get request and the results were returned in XML. At that time all requests were limited to XML responses and a maximum of 1,000 results per query.   Since then the entire API has gone through several reconstructions, rebranding and new search services.  Microsoft’s new Bing API replaced the older MSN search API and added several new search capabilities. These new features allow search data to be returned for web searches, image searches, new searches, and related search terms to name a few. Bing API Version 2.0 SourceTypes Web Searches for web content Sushi Image Searches for images on the web Sushi News Searches news stories Sushi InstantAnswer Searches Encarta online what is sushi, convert 5 feet to meters, x*5=7, and 2 plus 2 Spell Searches Encarta dictionary for spelling suggestions Phonebook Searches phonebook entries sushi in Los Angeles RelatedSearch Returns the query strings most similar to yours Ad Returns advertisements to incorporate with results I currently plan to start using the web search feature from the new Bing 2.0 API in an open source project related to exception management. Currently, it is still in the conception phase.

• Good design for a simple site that contains a blog

  - by bporter

  What is a good design for a simple web site with mostly static pages and a blog? I am helping a friend build this for their small business. We are looking for a simple approach that can be implemented fairly quickly. (I am a programmer and can help with coding, hosting, etc.) One option is to use a site like virb, which lets you choose from one of their themes and build a site pretty easily. You can also include a blog. They host the site for a pretty low monthly rate. I recommended this option, but my friend wants a design that is unique and custom. So, I took one of the themes and started modifying the HTML and CSS. This might still be a good option, but... ...If we are going to greatly modify it, why not just create the static pages from scratch and use something like Wordpress for the blog. Is this a good option? It looks fairly easy to integrate Wordpress with a site so that the design and behavior are really cohesive. Is this a good idea? Do you recommend any other approaches?

• How to do Cross Platform in own Engine? [on hold]

  - by Mineorbit

  At the Moment I finished the first game with my game engine(if I wanna call it like that) which is based in LWJGL. Now i'm worring if I could do crossplattforming in my engine. I build me a tool tool with a batch file to compile my project dir into an .exe . At first i'm looking to do it on Android with an comparable batch file. An link for an tutorial would be awesome! At next place there would be an renderer and audiosystem. If read that theres an OpenGL ES renderer, and I allready played a bit around with the Android SDK. But I use the Texture and Audio class in slick-util. So I thought about creating OOP classes that carry around the data and load it in an platform specific Buffer. A Link for an equaly easy-to-use Texture or Audio class would be awesome! Thats all for now! Answers would be awesome! Thanks, Mineorbit!

• Using 12.04 installation as a persistent pen drive

  - by Cawas

  Disclaimer: I aim to build a self contained pen drive with my application inside, so no matter about updates. Maybe I'm looking at the wrong linux distribution to do this... Please let me know if you think so. I've tried knoppix and even lubuntu, but they don't come with enough "drivers" for Unity3D to work. Creating a custom live persistent pen drive is a real pain and I'm trying for 1 day without any success. Sure, being able to do it would probably be ideal and occupy the minimum space. Using the installation image on a pen drive, however, is good enough and is really easy to create. We can even do it from any OS, using UNetBootin, LiLi USB Creator or some other methods. Straight forward. Some recommend installing it on a pen drive. But that requires a lot of space and, I believe, it won't behave as good as something meant to be installed on a usb disk, because of memory management. So, there are only a few negative points on using the installation image that I can think of. Question here, is how to remove those drawbacks: Having to press "Try Ubuntu". That's the big one. Couldn't find how. Unable to load everything on memory and keep on running without the pen drive (like this) Unable to remove "Install Ubuntu 12.04 LTS" app. Setting the ISO to use maximum amount of space for the OS will leave pen drive with zero space left and any file saved within it from ubuntu is inaccessible from the outside (when plugin the pen drive and not booting from it). Am I missing something? Can those points be fixed?

• Develop for Desktop and mobile use?

  - by ran2

  I am in the very beginning of developing an app / desktop program. I want it to be cross-platform and possibly also as a tablet version (preferably Android Icecream sandwich). Note that I need to run it offline. I thought about the following approaches: ADOBE Air, since I do not need much performance. Plus I did some web programming in the past which might be of some use. Afaik it would run on OS X and Windows and should run on mobile OSes, too. Qt. Found some nice Qt based desktop recently and read it also works on android. Plus I like the SDK. HTML5 / JS. Again my web background should help me here. I wont need no sever side scripts, thus it should work without installing anything but a browser. How easy could this be converted into an Android app? There might be a plethora of other (better) ways to do it, but I haven't thought of them yet. Can you help out? How would you create such an application. Would it be better to do some pure desktop client and then create tablet versions? Would you rather start to create a website and worry later on how to turn into an app?

• VSFTPD uploaded file permissions

  - by Katafalkas

  Let me first say that there are loads of topics regarding this, and I am sure i have seen them all by now. Still non of the solutions seem to help. I installed vsftpd. created a user ftp-data. Now I need that files uploaded by user ftp-data would have 755 permissions. Solving this should be as easy as adding: local_umask=002 file_open_mode=0755 but that did not help, then I have tried a number of variations of this, still did not help. The I added: chmod_enable=YES still did not help. At the moment I think that I am missing something very simple and obvious, just cant find it. Maybe someone could help me to find what I am missing. This is my config file: anonymous_enable=NO local_enable=YES write_enable=YES local_umask=002 anon_upload_enable=NO anon_mkdir_write_enable=NO dirmessage_enable=NO xferlog_enable=YES connect_from_port_20=YES xferlog_file=/var/log/xferlog listen=YES local_root=/var/www/ftp-gallery pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES

• New features for Expression Blend 4 Release Candidate

  - by kaleidoscope

  With Microsoft Expression Blend 4, you can create websites and applications based on Microsoft Silverlight 3 and Microsoft Silverlight 4, and desktop applications based on Windows Presentation Foundation (WPF) 3.5 with Service Pack 1 (SP1) and WPF4. Expression Blend provides new support for prototyping, interactivity through behaviors, special Silverlight functionality, and on-the-fly sample data generation. Expression Blend includes new behaviors that are quickly and easily configured Expression Blend offers new sample data, behaviors, and features of project templates to support the Model-View-ViewModel (MVVM) pattern The MVVM pattern is a way to structure a Silverlight or WPF application so that user interface (UI) objects are as decoupled as possible from the application's data and behavior. This makes it easier for design tasks and development tasks to be performed independently and without breaking each other. Essentially, your UI is the View. You bind objects in the View to properties and commands of the ViewModel, and the View can also call methods on the ViewModel. Compatible with Silverlight 3 and WPF 3.5 with Service Pack 1 (SP1) Interoperate able with Visual Studio. Included New Shapes: The Assets panel in Expression Blend contains a new Shapes category, including presets for the easy creation of arcs, arrows, callouts, and polygons. New Controls: Expression Blend has tooling support for the RichTextBox control in Silverlight. XAML cleanliness :Expression Blend generates less XAML with respect to animations and animation-related properties. MVVM project template: Expression Blend includes a new project template that offers a basic starting point for Model-View-ViewModel pattern applications. Run project with CTRL+F5:To improve consistency with Visual Studio, you can now invoke the Run Project command by pressing either CTRL+F5 or F5 Technorati Tags: Rituraj,Features of Expression Blend4 RC

• Country specific content vs global content

  - by Ando

  I have a global product presentation website myproduct.com For certain countries I also own the country domain: myproduct.co.uk, myproduct.com.au, myproduct.es, myproduct.de, etc. The presentation website is translated in multiple languages and I set up redirects: myproduct.es will redirect to myproduct.com/es/, myproduct.de will redirect to myproduct.com/de/, etc. . The content so far is the same, just translated in different languages. The advantages are that it's easy to keep the content aligned - everything is managed from one centralized dashboard (I'm using Wordpress with qtranslate). Now I'm running into trouble as for different countries I want localized content - for UK I want to run different promotions and use a different reseller than for .com.au so I would like that users coming from myproduct.co.uk see something different than those coming from myproduct.com.au (and not be redirected to myproduct.com as they are right now). How can I achieve this? I could duplicate the whole main website and modify only certain parts but then I would have a lot of duplicate content (e.g. info about how the product works) and I would have pages that are likely to change (FAQ page) that I would have to keep updated over all websites. I can duplicate only partially the main website: on the localized website I would have only the pages that are different and then all other links would point to the .com site. This would solve the duplication problem but would cause confusion for the user as you would navigate from .co.uk to .com without noticing and then wonder how to get back. Other, better option?

• Web hosting providers for businesses (with offsite backups, disaster recovery options, etc.) [closed]

  - by Harry Muscle

  Possible Duplicate: How to find web hosting that meets my requirements? I'm wondering if anyone can point me in the direction of a couple of web hosting providers that are geared towards businesses. By this I mean providers that make it easy to create daily off site backups, are aware that websites require disaster recovery options and have these in place or are able to assist with them, etc. We currently have about a dozen sites with various providers, however, I've been asked to consolidate all of these into one provider and create a full disaster recovery plan. Unfortunately it seems like most providers are geared towards average users that don't require all these extra bells and whistles that businesses need. For example, HostGator, which is a very popular and well reviewed provider, doesn't even allow you to schedule full backups, they have to be manually requested via cPanel and then downloaded once available. If anyone can point out a couple companies that might be able to help with these sorts of things that would be much appreciated. Thanks, Harry P.S. I should also add that we are hoping to stay away from having to manage our own server, we're hoping for a fully managed solution like what HostGator would offer for example.

• organization of DLL linked functions

  - by m25

  So this is a code organization question. I got my basic code working but when I expand it will be terrible. I have a DLL that I don't have a .lib for. Therefore I have to use the whole loadLibrary()/getprocaddress() combo. it works great. But this DLL that i'm referencing at 100+ functions. my current process is (1) typedef a type for the function. or typedef short(_stdcall *type1)(void); then (2) assign a function name that I want to use such as type1 function_1, then (3) I do the whole LoadLibrary, then do something like function_1 = (type1)GetProcAddress(hinstLib, "_mangled_funcName@5"); normally I would like to do all of my function definitions in a header file but because I have to do use the load library function, its not that easy. the code will be a mess. Right now i'm doing (1) and (2) in a header file and was considering making a function in another .cpp file to do the load library and dump all of the (3)'s in there. I considered using a namespace for the functions so I can use them in the main function and not have to pass over to the other function. Any other tips on how to organize this code to where it is readable and organized? My goals are to be able to use function_1 as a regular function in the main code. if I have to a ref::function_1 that would be okay but I would prefer to avoid it. this code for all practical purposes is just plane C at the moment. thanks in advance for any advice!

• Compressing 2D level data

  - by Lucius

  So, I'm developing a 2D, tile based game and a map maker thingy - all in Java. The problem is that recently I've been having some memory issues when about 4 maps are loaded. Each one of these maps are composed of 128x128 tiles and have 4 layers (for details and stuff). I already spent a good amount of time searching for solutions and the best thing I found was run-length enconding (RLE). It seems easy enough to use with static data, but is there a way to use it with data that is constantly changing, without a big drop in performance? In my maps, supposing I'm compressing the columns, I would have 128 rows, each with some amount of data (hopefully less than it would be without RLE). Whenever I change a tile, that whole row would have to be checked and I'm affraid that would slow down too much the production (and I'm in a somewhat tight schedule). Well, worst case scenario I work on each map individually, and save them using RLE, but it would be really nice if I could avoind that. EDIT: What I'm currently using to store the data for the tiles is a 2D array of HashMaps that use the layer as key and store the id of the tile in that position - like this: private HashMap< Integer, Integer [][]

• Need to run a .sh as root on boot or login

  - by Graymayre

  Still new with linux and running ubuntu 12.10 I have a wireless stick (ae2500) which has known issues that has been partially solved using ndiswrapper. However, to use it I must run the same scripts every time I reboot, effectively uninstalling and reinstalling the driver. I made a .sh file to run every time to make it easy, but I must do the sudo login everytime. There are three solutions I am looking for and although not all are necessary to solve this particular problem, I would still like to know them all for learning purposes. run scripts or file.sh on boot (as well as other programs) run scripts or file.sh automatically with root privileges make the install permanent so as not to have to go through the process every time. Any additional information that can help me regarding this that I did not think to ask (including streamlining my commands), or general knowledge, would be greatly appreciated. Following are the contents of the file. I pretty much just made it as I would have entered it. cd ~/ndiswrapper-1.58rc1 sudo modprobe -rf ndiswrapper sudo rm /etc/modprobe.d/ndiswrapper.conf sudo rm -r /etc/ndiswrapper/* sudo depmod -a sudo make uninstall sudo make sudo make install sudo ndiswrapper -i bcmwlhigh5.inf ndiswrapper -l sudo modprobe ndiswrapper

• Basic procedural generated content works, but how could I do the same in reverse?

  - by andrew

  My 2D world is made up of blocks. At the moment, I create a block and assign it a number between 1 and 4. The number assigned to the nth block is always the same (i.e if the player walks backwards or restarts the game.) and is generated in the function below. As shown here by this animation, the colours represent the number. function generate_data(n) math.randomseed(n) -- resets the random so that the 'random' number for n is always the same math.random() -- fixes lua random bug local no = math.random(4) --print(no, n) return no end Now I want to limit the next block's number - a block of 1 will always have a block 2 after it, while block 2 will either have a block 1,2 or 3 after it, etc. Before, all the blocks data was randomly generated, initially, and then saved. This data was then loaded and used instead of being randomly called. While working this way, I could specify what the next block would be easily and it would be saved for consistency. I have now removed this saving/loading in favour of procedural generation as I realised that save whiles would get very big after travelling. Back to the present. While travelling forward (to the right), it is easy to limit what the next blocks number will be. I can generate it at the same time as the other data. The problem is when travelling backwards (to the left) I can not think of a way to load the previous block so that it is always the same. Does anyone have any ideas on how I could sort this out?

• Get Our New Book: The How-To Geek Guide to Windows 8

  - by The Geek

  Lets face it, Windows 8 is a major change to Windows, and for many, quite confusing. Today we’re releasing our very very first book: The How-To Geek Guide to Windows 8, which is written to be easy enough for anybody to understand, but comprehensive enough for experts to enjoy. There’s over a thousand screenshots and pictures in the book to help you get the hang of navigating around Windows 8, and nearly a thousand pages of content so there’s nothing you won’t understand. Everything is covered in traditional How-To Geek style, with step-by-step instructions complete with pictures, more pictures, and even more pictures. There’s over a thousand pictures in this book! This book is priced very reasonably for a nearly thousand-page computer book, at only $9.99 on the Amazon Kindle store. We don’t use DRM, and you can use it on any device that supports Kindle—including reading it directly in your web browser. If you like How-To Geek, you’ll like this book.
