• How to recover broken dpkg after lucid-bleed ppa-purge?

  - by TryTryAgain

  Did a ppa-purge of lucid-bleed and dpkg didn't downgrade properly and now it is broken. dpkg: PreDepends: tar (>= 1.23) but 1.22-2ubuntu1 is to be installed What scares me is when simulating the removal of dpkg I get: Removing this package may render the system unusable. Are you sure you want to do that? and then the list of packages which depend on it, which will also be removed, is obviously very long. Is it safe for me to remove dpkg just to reinstall it? How would I ensure the list of packages which were also removed are then reinstalled? Will forcing the version of dpkg help? (FYI: simulating a forced version brings up a much smaller list of applications which will also be removed). Any other suggestions? Additional information based on comments: ppa-purge log: http://pastebin.com/1kT8cLvP If I sudo apt-get install dpkg=1.15.5.6ubuntu4.5 I get The following packages have unmet dependencies: libdpkg-perl: Depends: dpkg (= 1.15.8) but 1.15.5.6ubuntu4.5 is to be installed which sucks because that means more would be broken after doing so...but when I force the version through Synaptic I get: To be removed alien, build-essential, cdbs, checkinstall, debhelper, devscripts, dpkg-dev, google-earth-stable, googleearth-package, libdpkg-perl, lintian, lsb, lsb-core, lsb-cxx, lsb-desktop, lsb-graphics, lsb-languages, lsb-multimedia, lsb-printing, lsb-qt4, lsb-security, ubuntu-dev-tools.

• Cannot access personal website from home IP. More details inside.

  - by GX67

  This is a recent problem I've been having. My site can be accessed from almost everywhere else except from my home IP, where I do most of my editing/updating, etc. I've tested my connection from my school's network, a friend's connection from out of state (multiple states), and through a tethered connection with my friend's Android. It works in all those cases, both viewing, accessing the cPanel, and using FTP. Here's the problem that happens to me when I try to view it from my home IP: The page times out in Firefox, IE, and Chrome. Using the cmd, I ran tracert and ping, both as failed attempts. Log here. downforeveryoneorjustme.com says my site is up. So do the other site checkers. I can't access my cPanel or FTP accounts. I can't access the host site. (I use perfectz.info for hosting, and I can't access their site either.) System settings: No firewall enabled. Ports are seemingly properly forwarded. (e.g. The ports are open in the router settings, and are open everywhere else.) I have an email forwarder set up from the cPanel that works just fine. (i.e. I can receive emails sent to that address. If any other information is needed, I'll do my best to provide it. UPDATE @ilhan: I use two things: 1) The site cPanel from in-browser. 2) Dreamweaver CS5 FTP. @Matthias: I tested both, and it passes the dual stack with a 10/10. What should I do then?

• What You Said: How You Sync and Organize Your Bookmarks

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite techniques for synchronizing and organizing your browser bookmarks. Now we’re back to highlight the most popular techniques, tricks, and services. By far and away, Xmarks was the most frequently mentioned service. For the unfamiliar, Xmarks is a bookmark syncing service that is packed with features. Not only does Xmarks sync bookmarks between browsers and/or computers it also supports iOS, Android, and BlackBerry (mobile integration requires an upgrade to the premium account). In addition to syncing the bookmarks it also integrates with your search results so you can see how other Xmarks users have ranked sites within your search results. Steve-O-Rama highlights one of the many benefits of Xmarks: Xmarks seems to do the job for me. I’ve got a handful of machines, each with three or four browsers; over the years, I’ve accumulated thousands of bookmarks, stretching across many areas of interest. Trying to keep them all straight had been quite a struggle until Xmarks came along. I freaked out when the company was acquired by LastPass, but was subsequently relieved when they continued the free service. Xmarks has a very nice web interface to access, export, search, organize, and do many other things with your bookmarks. In this way, even if I’m on the go, I can access every bookmark I’ve made. Even so, I still make occasional local backups, directly from the browsers to a network folder. Delicious bookmarks, another veteran of the bookmark syncing services, had a fair number of supporters among the HTG readership.

• MySQL - Configuration

  - by Stuart Brierley

  Having previously detailed how to install MySQL Server, the next step is configuring MySQL. The MySQL configuration wizard can either be run immediately following installation from the MySQL installation wizard or manually from the Start Menu. Following the splash screen you can then choose whether to run a detailed or standard configuration. The detailed configuration allows you to create the optimal configuration for your specific machine, whereas the standard configuration creates a general configuration that can then be manually tuned. I chose detailed.   You are then asked to choose the type of server instance that is being configured. In this case it is a developer machine. Following this you are asked to choose the type of database usage that you expect on the server. I opted for multifunctional. You must then specify the location of the InnoDB tablespace.   Next specify the number of concurent connections to the server.   Now you must configure the networking options. I left the Strict mode enabled as this is the recommended option, but I disabled TCP/IP networking as I wanted to restrict this MySQL installation to the local machine only.   Set the character set that is best suited to your use - for me this was the default standard character set. Next up is the option to run MySQL as a service and whether or not to include the mysql dircetories in the windows PATH. I kept the install as a windows service option enabled, but unchecked the Launch MySQL server automatically option. This is because I only wanted MySQL running when I specifically want to use it. I also enabled the include in windows PATH option.   You can then change the security settings for the mysql installation. I opted to change the root password, disable root from local machines and disable annoymous access.   You are now ready to execute the configuration.   Once completed you should hopefully see the completed screen with lots of nice ticks against the various configuration tasks.

• Update kernel patch for VMware Player 4.0.3

  As I stated some days ago, after upgrading to Ubuntu Precise Pangolin, aka 12.04 LTS, I had a minor obstacle with VMware products. Today, VMware offered to upgrade to Player 4.0.3 due to security-related reasons. Initially, I thought that this update might have the patch for kernel 3.2.0 integrated but sadly that is not the case. 'Hacking' the kernel patch My first intuitive try to run the existing patch against the sources of VMware Player 4.0.3 failed, as the patch by Stefano Angeleri (weltall) is originally written explicitely against Workstation 8.0.2 and Player 4.0.2. But this is nothing to worry about seriously. Just fire up your favourite editor of choice and modify the version signature for VMware Player, like so: nano patch-modules_3.2.0.sh And update line 8 for the new version: plreqver=4.0.3 Save the shell script and run it as super-user (root): sudo ./patch-modules_3.2.0.sh In case that you previously patched your VMware sources you have to remove some artifacts beforehand. Otherwise, the patch script will inform you like so: /usr/lib/vmware/modules/source/.patched found. You have already patched your sources. Exiting In that case, simply remove the 'hidden' file and run the shell script again: sudo rm /usr/lib/vmware/modules/source/.patchedsudo ./patch-modules_3.2.0.sh To finalise your installation either restart the vmware service or reboot your machine. On first start VMware will present you their EULA which you have to accept, and everything gets back to normal operation mode. Currently, I would assume that in case of VMware Workstation 8.0.3 you can follow the same steps as just described.

• Fresh install on SSD with Ubuntu and Windows Vista, using whole disk encryption for Ubuntu

  - by nategator

  I would like to do a fresh install on a OCZ Vertex Plus R2 SSD 60GB drive I purchased on the cheap. Since the AES-encryption looks like it may not work optimally for this drive, I would like to set up a dual-boot to Windows Vista (the only Windows copy I have for clean install purposes) and Ubuntu 12.04 with the best encryption scheme possible. My plan is to have Windows around just in case I need to use a program that won't work with Wine and Ubuntu as my daily OS with all of my information secured in case the laptop is ever stolen or sold. Although this setup will not provide a lot of space, I think I can squeeze both OSes and have enough for second-computer office tasks. So, my questions are: Which OS should I install first, Ubuntu or Vista? Any special considerations when partitioning the drive? How should I install Ubuntu to ensure full disk encryption for the Linux partition(s) and or my daily computing? Is there a significant performance upgrade with doing a solo install of Ubuntu instead of a dual boot setup? Will TRIM, for example, work correctly? Are there any significant security concerns with going the route of a dual-boot, other than the fact that any activity on Windows may be fully recoverable if the drive is stolen or sold? Thanks in advance!

• Bazaar - pull the last revision only (and not the whole branch)

  - by Sandman4

  Shortly: How can I take the latest revision (only) from a remote bazaar repository and add it as a new revision to a local repository. Background: I have a development system and a production system. On a development system there's a bazaar repository having branch with lots of development revisions. Once in a while I want to incorporate the latest developments into production system. I want to do so by some sort of "pulling" (development system can not connect to production for security reasons, but production can initiate connection to development). On the production, I don't want the whole development revision history, only those revisions which actually go into production (normally it's the branch tip). Yet I want version control on the production system to keep track of what actually goes into production each time. bzr pull pulls the whole branch. bzr pull --revision=last:1 also pulls the whole branch, up to the specified revision. bzr merge --pull --revision=last:1 also pulls the whole branch. bzr merge --pull --revision=last:2..last:1 and bzr merge --pull --change=last:1 both pull only the new changes introduced in the latest revision, but not changes introduced in the older revisions. With lightweight checkout I have no track of revisions which are pulled into production - local working tree remains part of the remote repository The only way I see so far is importing the working tree using some rsync or scp and committing them to a local branch afterwards. Any better ideas ?

• Going on 15 months for me...

  - by Ratman21

  About 5 face to face interviews, 4 telephone ones and except for the two weeks Census Job. But, after 15 months looking for work, I am still with out a JOB. What is wrong here or with me? Let’s see, hard worker (check), self motivated to do well on a Job (Check), Certified CompTIA A+, Security+  and Network+ Technician (Check), 20 + years experience in “IT” (CHECK), in good health, in 20 years of work only 15 days off due to health issues (Check), 18 years experience as technical Help Desk support (Check), can still work better than younger personal (Check), Strong trouble shooting skills for software, computer hard ware and circuit issues (Check) and Multiple software languages (Hey I have done some programming) Check. Hmm I don’t see any problem with me (of course I could have missed something, please let me know if you see what I am missing).    Now as to what have I been up to since I last blogged. The same things of course, Job hunting, job hunting and study.   I have set up sim of my home LAN and will be adding a wireless print server to the sim and in real life, soon.  I was able to pull up and copy the examples of Cisco router commands that I had on my old lap top, to my newer PC. Every time I used a new command while working the NOC on my last job.   I would cut and past a copy of the command on the router (and what it did) I was working on.  Along with notes on the problem and commands use for same router. I used these to make documentation for on how to handle these types of issues, for the other Operation Techs. My old notes are helping me in studying for the CCENT test.    As to Love Dare, I think it will take more like 40 weeks, than the 40 days of the book. Yes I am making progress, slow but, it is progress. I will have more on that in my next blog.

• Benefits of Server-side Coding

  There are numerous advantages to server scripting languages over client side languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripting are scripts that are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9 years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server-side scripts and JavaScript used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid. However, I would have to say that my personal experience would have to sway me in deciding what type of languages to use for form validation because they both have advantages and disadvantages based on the each situation.

• Why are embedded device apps still written in C/C++? Why not Java programming language?

  - by hinkmond

  At the recent Black Hat 2014 conference in Sin City, the Black Hatters were focusing on Embedded Devices and IoT. You know? Make your networked-toaster burn your bread 10,000 miles away, over the Web for grins and giggles. Well, apparently the Black Hatters say it can be done pretty easily these days, which is scary. See: Securing Embedded Devices & IoT Here's a quote: All these devices are still written in C and C++. The challenges associated with developing securely in these languages have been fought for nearly two decades. "You often hear people say, 'Well, why don't we just get rid of the C and C++ language if it's so problematic. Why don't we just write everything in C# or Java, or something that is a little safer to develop in?'," DeMott says. Gah! Why are all these IoT devices still using C/C++? Of course they should be using Java SE Embedded technology! It's a natural fit to use for better security on embedded devices. Or, I guess, developers really don't mind if their networked-toasters do char their breakfast. If it can be burned, it will be... That's what I say. Unless they use Java. Hinkmond

• New Book - Oracle ADF Enterprise Application Development Made Simple

  - by Shay Shmeltzer

  It's nice to see another ADF book out there, this one from Sten Vesteli titled "Oracle ADF Enterprise Application Development Made Simple" comes from Packet Publishing Unlike other ADF books out there, this one doesn't aim to teach you Oracle ADF, but rather focuses on the right way to structure and manage a project that leverages ADF. This is a welcomed addition to the bookshelf for people who are looking into ADF based development. One thing I find is that some organization just start developing an ADF application without first doing much planning, something that is understandable given that it is very easy to start building a prototype with ADF and then just grow it into a full blown application. However, as the book points out, doing a bit of planning before you delve into the actual project development can save you a lot of time in the future. For example it is much better to have the right breakdown and structure of your project to allow you to do efficient team development right out of the gate, then to find out 1 year down the road that you are dealing with one monolithic size project which is hard to manage. The book touches on such topics as project organization (workspaces, projects, packages), planning your infrastructure (templates, framework classes), coding standards, team structure, etc. It also covers various aspects of application lifecycle management such as versioning, build, testing, deployment and managing requirements and tasks and how all of those are done when using JDeveloper and Oracle ADF. It's nice to see that the book covers working with Oracle Team Productivity Center - a solution that might not be getting the exposure it deserves. The book also has some chapters about security, internalization and customization of applications both with MDS and with ADF Faces skins (and it even covers the brand new skin editor). Overall I think this is definitely a book you should read if you are about to start your way on a new enterprise scale ADF application. Taking into account the topics that the book discusses before you start your work will save you time and effort down the road. By the way, don't forget that as an OTN member you can get discount on this and other books.

• Writing Web "server less" applications

  - by crodjer

  TL;DR What are the prospects of write applications which are completely based on a REST database server (CouchDB) and web applications which directly access the DB instead of having a web server in between? I recently started looking up some NoSQL databases. MongoDB seems to be a popular choices. I also liked the project. But I personally liked the REST interface of CouchDB. So what I wanted to know is if there was the possibility of applications (maybe cached apps in web browser, a chrome extension etc.) which could just just query the database directly with no requirement of a webserver in between. All the computational logic would reside in the client application and the database will do what it does, CRUD. Since mostly (I don't know which doesn't) client frameworks support REST quaries, it could be a good way writing applications well optimized for respective framework. These applications though won't be doing complicated computation, but still provide enough functionality which could replace lots of conventional applications. Are existing resources and projects which would help me move towards writing such applications and also the scope and moving towards developing in this way? Are their any technical/security issues with this? This post will help me decide to look into project like CouchDB (and maybe Dive into Erlang later) or stay with the conventional frameworks (like django) and SQL databases. Update A specific point of such apps I had in mind is creation of offline applications just by replicating couchdb data on client.

• How to implement a no-login authentication system

  - by mrwooster

  I am looking to build a very loose authentication system that can track a user and link submitted data/comments to a specific user. The submissions are essentially anonymous, but a user may want to edit his submission/comment at a later date. I want the experience to be as smooth as possible so do not want to ask users to sign up for an account and then login each time. There is no point as their submissions are not in their name and to another user browsing the site, there is no way of linking a submission to a specific user (think anonymous comments on a blog post or pastie). However, the user should have the ability to edit (at least in the short term) the content they have posted. The way I imagine doing this would be to place a unique identifier in a cookie on the users machine. This would enable me to link a submission to a user, and while that cookie remained on the users machine, I would allow them to edit their content. Of course, if the cookie is lost, or the user accesses the site from a different browser, then they would not be able to edit their content, but this is not really an issue, they can always resubmit a new piece of content. Is there a better way of doing this? How can I implement this so that the user can edit their data for the longest possible amount of time.

• I know how to program, and how to learn how to program, but how/where do you learn how to make systems properly?

  - by Ryan

  There are many things that need to be considered when making a system, let's take for example a web based system where users log in and interact with each other, creating and editing content. Now I have to think about security, validation (I don't even think I am 100% sure what that entails), "making sure users don't step on each others feet" (term for this?), preventing errors in many cases, making sure database data doesn't become problematic through unexpected... situations? All these things I don't know how or where to learn, is there a book on this kind of stuff? Like I said there seems to be a huge difference between writing code and actually writing the right code, know what I mean? I feel like my current programming work lacks much of what I have described and I can see the problems it causes later, and then the problems are much harder to solve because data exists and people are using it. So can anyone point me to books or resources or the proper subset of programming(?) for this type of learning? PS: feel free to correct my tags, I don't know what I am talking about. Edit: I assume some of the examples I wrote apply to other types of systems too, I just don't know any other good examples because I've been mostly involved in web work.

• What stops HTML5 and JS apps to perform as good as native apps?

  - by Amogh Talpallikar

  From what I understand, HTML is a mark-up language, so is the content of XAML, XIB and whatever Android uses and other native UI development frameworks. JavaScript is a programming language used along with it to handle client side scripting which will include things like event handling, client side validations and anything else C#,Java,Objective-C or C++ do in various such frameworks. There are MVC/MVVM patterns available in form frameworks like Sencha's, Angular etc. We have localStorage in form of both sqlite and key-value store as other frameworks have and you have API specification for almost everything that it missing. Whenever a native UI frameworks has to render UI , it has to parse a similar the markup and render the UI. Question break-down What stops from doing the same in HTML and JS itself ? Instead of having a web-control or browser as a layer in between why can't HTML(along with CSS) and JS be made to perform the same way ? Even if there is a layer,so does .net runtime and JVM are in other cases where C++,C are not being used. So Lets take the case of Android, like Dalvik, why Can't Chromium be another option(along with dalvik and NDK) where HTML does what android markup does and JavaScript is used to do what Java does ? So the Question is, Even if current implementations aren't as good, but theoretically is it possible to get HTML5 based applications to work as other native apps specially on mobile ?

• The premier support for Sun Cluster 3.1 ended

  - by JuergenS

  In October 2011 the premier support for Sun Cluster 3.1 ended. See details in Oracle Lifetime Support Policy for Oracle and Sun System Software document. There no 'Extended Support' and the 'Sustaining Support Ends' is indefinite. But for indefinite 'Sustaining Support' I like to point out from the mentioned document (version Sept. 2011) on page 5: Sustaining Support does NOT include: * New program updates, fixes, security alerts, general maintenance releases, selected functionality releases and documentation updates or upgrade tools * Certification with most new third-party products/versions and most new Oracle products * 24 hour commitment and response guidelines for Severity 1 service requests *Previously released fixes or updates that Oracle no longer supports This means Solaris 10 9/10 update9 is the last qualified release for Sun Cluster 3.1. So, Sun Cluster 3.1 is not qualified on Solaris 10 8/11 Update10. Furthermore there is an issue around with SVM patch 145899-06 or higher. This SVM patch is part of Solaris 10 8/11 Update10. The 145899-06 is the first released patch of this number, therefore the support for Sun Cluster 3.1 ends with the previous SVM patches 144622-01 and 139967-02. For details about the known problem with SVM patch 145899-06 please refer to doc 1378828.1. Further this means you should freeze (no patching, no upgrade) your Sun Cluster 3.1 configuration not later than Solaris 10 9/10 update9. Or even better plan an upgrade to Solaris Cluster 3.3 now to get back to full support.

• Create MSDB Folders Through Code

  You can create package folders through SSMS, but you may also wish to do this as part of a deployment process or installation. In this case you will want programmatic method for managing folders, so how can this be done? The short answer is, go and look at the table msdb.dbo. sysdtspackagefolders90. This where folder information is stored, using a simple parent and child hierarchy format. To add new folder directly we just insert into the table - INSERT INTO dbo.sysdtspackagefolders90 ( folderid ,parentfolderid ,foldername) VALUES ( NEWID() -- New GUID for our new folder ,<<Parent Folder GUID>> -- Lookup the parent folder GUID if a child or another folder, or use the root GUID 00000000-0000-0000-0000-000000000000 ,<<Folder Name>>) -- New folder name There are also some stored procedures - sp_dts_addfolder sp_dts_deletefolder sp_dts_getfolder sp_dts_listfolders sp_dts_renamefolder To add a new folder to the root we could call the sp_dts_addfolder to stored procedure - EXEC msdb.dbo.sp_dts_addfolder @parentfolderid = '00000000-0000-0000-0000-000000000000' -- Root GUID ,@name = 'New Folder Name The stored procedures wrap very simple SQL statements, but provide a level of security, as they check the role membership of the user, and do not require permissions to perform direct table modifications.

• MvcReportViewer v.0.4.0 is available!

  - by Ilya Verbitskiy

  Originally posted on: http://geekswithblogs.net/ilich/archive/2014/06/04/mvcreportviewer-v.0.4.0-is-available.aspxToday I released new version of MvcReportViewer. This release contains mostly bug fixes reported by library users. I am glad to see that Open Source model works and people try to contribute to the project! Thank you everybody for your bug repots and help with the project. Version 0.4.0 Added support for ASP.NET MVC 5 Removed jQuery dependency. I have not tested it on IE8 or earlier versions. Any help with testing is welcome! Fixed problem with SSRS keep-alive cookies. Keep-alive cookies are issued every time a report is opened during a browser session. Many people don't restart their browsers and in my case, Chrome doesn't get rid of the cookie session data on close - had to manually delete them for the reports to start working again. I added KeepSessionAlive control settings to manage SSRS keep-alive behavior. It is set to false by default to fix Bad Request 400: Request Too Long issue. You can find usage example in Fluent.cshtml. Fixed the bug when ReportViewer Control parameters was not parsed when ShowParameterPrompts parameter had not been set. Changed public static MvcReportViewerIframe MvcReportViewer method to use IEnumerable<KeyValuePair<string, object>> reportParameters instead of simple object. The reason is users reported that they mostly use multiple report parameters’ values. Added support for SSRS hosted on Windows Azure. Users should set MvcReportViewer.IsAzureSSRS property to true in Web.config to use Windows Azure authentication. I do not have Windows Azure SSRS and build the code using http://msdn.microsoft.com/en-us/library/gg552871.aspx#Authentication article. It would be nice if somebody from community tested the change or provided me a test report on Windows Azure for testing purposes.

• New "delay" keyword for JavaScript

  I had a great idea for a new javascript keyword "delay", but I don't know what I can do to bring it to the new specification. Also I want to know what you guys think about it and if it's even realistic. What does the delay keyword ? The delay keyword does nothing more than stop the execution of the current stack and immediately continues to the next "job" in the queue. But that's not all! Instead of discarding the stack, it adds it to the end of the queue. After all "jobs" before it are done, the stack continues to execute. What is it good for? delay could help make blocking code non-blocking while it still looks like synchronous code. A short example: setTimeout(function(){ console.log("two"); },0); console.log("one"); delay; //since there is currently another task in the queue, do this task first before continuing console.log("three"); //Outputs: one, two, three This simple keyword would allow us to create a synchronous-looking code wich is asynchronous behind the scenes. Using node.js modules, for example, would no longer be impossible to use in the browser without trickery. There would be so many possibilites with such a keyword! Is this pattern useful? What can I do to bring this into the new ECMAscript specification? Note: I asked this previously on Stack Overflow, where it was closed.

• Diagnosing Bootstrap 3 Glyphicon Button Icons Not Showing

  - by Paulb

  I have a glyphicons in Bootstrap 3. They work very nicely here: latest Chrome latest Firefox latest Safari latest Explorer latest Android At one facility, the glyphicons don't show. The buttons come up blank. How do I troubleshoot? They are security sensitive there. I don't have systems or network access.. and am not in a position to request that. Troubleshooting with advanced tools isn't going to happen. Here's what I have access to: Internet Explorer 9 Behind a very secure firewall Sometimes, I think the glyphs not showing is the IE 9.. but my code should be addressing that. Sometimes, I think their firewall is blocking the CDN. Can I enter a URL into a browser to test if the CDN is there? Sometimes, I think my FB share and like buttons upset this facilty's firewall, and they tie the whole thing down. Any suggestions at how I begin to research this? Or maybe you have an outright idea for IE 9 and glyphs (though my code is very-very close to the demo's which work).

• Javascript Canvas Drawing Efficiency

  - by jujumbura

  I have just recently started some experiments with game development in Javascript/HTML5, and so far it has been going pretty well. I have a simple test scene running with some basic input handling, and a hundred-ish drawImage() calls with a few transforms. This all runs great on Chrome, but unfortunately, it already chugs on Firefox. I am using a very large canvas ( 1920 x 1080 ), but it doesn't seem like I should be hitting my limit already. So on that note, I was hoping to ask a few questions: 1) What exactly is done on the CPU vs. the GPU in terms of canvas and drawImage()? I'm afraid the answer is probably "it depends on the browser", but can anybody give me some rules of thumb? I naively imagined that each drawImage call results in a textured quad on the GPU with the canvas effectively being a render target, but I'm wondering if I'm pretty far off base there... 2) I have seen posts here and there with people saying not to use the translate(), rotate(), scale() functions when drawing on the canvas. Am I adding a lot of overhead just by adding a translate() call, as opposed to passing in the x,y to drawImage()? Some people suggest using "transate3d", etc., which are CSS properties, but I'm not sure how to use them within a scene. Can they be used for animated sprites within a single canvas? 3) I have also seen a lot of posts with people mentioning that pre-building canvases and then re-using them is a lot faster than issuing all the individual draw calls again. I am guessing that my background should definitely be pre-built into a canvas, but how far should I take this? Should I maintain an individual canvas for each sprite, to cache all static image data when not animating? Thank you much for your advice!

• Request format is unrecognized for URL unexpectedly ending exception in web service.

  - by Jalpesh P. Vadgama

  Recently I was getting error when I am calling web service using Java script. I searching on net and debugging I have found following things. Any web service support three kinds of protocol HttpGet,HttpPost and SOAP. In framework 1.0 it was enabled by default but after 1.0 framework it will not be enabled by default due to security issues and WS-Specifications. So we have to enabled them via putting configuration settings in web.config. Here is the code for that. <configuration> <system.web> <webservices> <protocols> <add name="HttpGet"></add> <add name="HttpPost"></add> </protocols> </webservices> </system.web> </configuration> Hope this will help you. Stay tuned for more. Till that Happy programming!!!. Technorati Tags: WebService,Request,Javascript,Ajax
