  • .htaccess rules to rewrite URLs to front end page?

    - by Dizzley
    I am adding a new application to my site at example.com/app. I want views at that URL to always open myapp.php. E.g. example.com/app -> example.com/app/myapp.php and example.com/app/ -> example.com/app/myapp.php What's the correct form of rewrite rules in the .htaccess file? I've got: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /app/ RewriteRule ^myapp\.php$ - [L] RewriteRule ^myapp.php$ - [L] RewriteRule . - [L] </IfModule> ...based on what the Wordpress front-end does. But all I see at example.com/app is a directory of files. :( (I put those rewrites at the top of my .htaccess file). Any ideas? Update What actually worked: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/app(/.*)?$ [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule . /app/myapp.php [L] This is good because: Explicit or implicit calls to app/myapp.php work. example.com/app redirects to app/myapp.php example.com/app/ redirects to app/myapp.php example.com/app/subfunction redirects to app/myapp.php All other calls to example.com/otherstuff are untouched. Item 4 is Wordpress-like Front Controller pattern behaviour. I think that rule RewriteCond %{REQUEST_URI} ^/app.*$ [NC] needs refining as it allows /app-oh-my-goodness etc. through too. Thanks for the answers.

  • preseeded installation keeps asking for confirmation while creating RAID-Partitions on certain hardware-platform

    - by Marc Shennon
    I am aware of the partman-md/confirm_nooverwrite thing, that was the solution to most of this problems in the past. The thing is, that the preseed-file works for almost all hardware-platforms I tested, but only for one (Primergy MX130) it keeps asking for confirmation, before writing the partition-layout to the disks. All machines I tested are running with two SATA Disks, nothing special. I'm not really sure, what information could be needed in order to investigate the cause of this behaviour, but I would of course be willing to provide more information, if someone has an idea. Relevant part of the preseed file is the following: d-i partman-auto/disk string /dev/sda /dev/sdb d-i partman-auto/method string raid d-i partman-md/confirm boolean true d-i partman-partitioning/confirm_write_new_label boolean true d-i partman-md/device_remove_md boolean true d-i partman/choose_partition select finish d-i partman-md/confirm_nooverwrite boolean true # Write the changes to disks? d-i partman/confirm boolean true d-i mdadm/boot_degraded boolean true # RECIPE # Next you need to specify the physical partitions that will be used. d-i partman-auto/expert_recipe string \ multiraid :: \ 500 10000 1000000000 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 512 1000 786 raid $lvmignore{ }\ $primary{ } \ method{ raid } \ . \ 8192 10240 10240 raid $lvmignore{ }\ method{ raid } \ . # Parameters are: # <raidtype> <devcount> <sparecount> <fstype> <mountpoint> <devices> <sparedevices> d-i partman-auto-raid/recipe string \ 1 2 0 ext4 / /dev/sda1#/dev/sdb1 . \ 1 2 0 ext2 /boot /dev/sda2#/dev/sdb2 . \ 1 2 0 swap - /dev/sda5#/dev/sdb5 .

  • Password protect an alias virtual directory

    - by Jason
    I have a main domain being hosted through CPanel. I also have a sub-domain that I would like to appear as a path under the main domain instead of as a sub-domain. So I have: http://example.com/ pointing to the main hosted file. http://example.com/mydir pointing to the subdomain files. This is achieved by a httpd.conf include from the main domain section to set an alias: alias /mydir /path/to/subdomain/files/ Now, that works fine so far. The problem is that if a .htaccess file under /path/to/the/subdomain/files/ contains an error, the alias is completely skipped, and /mydir goes instead to the main host files. That is kind of surprising to me - I would expect an error to return an error instead. Now the killer: if I try to password protect /path/to/subdomain/files/, then trying to access http://example.com/mydir will again attempt to deliver from under the main hosted files and not from /path/to/subdomain/files/ I am not seeing any errors reported on the .htaccess file in the apache error log, so I am assuming the .htaccess is valid: AuthUserFile /path/to/valid/readable/.htpasswd AuthName "Secure Access" AuthType Basic Require valid-user This kind of behaviour does not seem right to me. Is there something obvious that could be causing it? Or is this just the way it works? Perhaps using an alias is the wrong way to go?

  • Compiz: How can I pin osd-lyrics to the Desktop?

    - by joebuntu
    Hey ya, I have certain applications pinned to my desktop. such as Rainlendar (1), which offers this option in the settings window conky (2), with "own_window_type normal" in my ~/.conkyrc Rhythmbox's Desktop Cover Art plugin (3), a python plugin sticked to the desktop. They all hide nicely below all other Windows. I set Compiz to not minimize them on "show desktop" command using "window rules". I also use [osd-lyrics][1] to display music lyrics. It's default behaviour is to stick always on top, which is irritating sometimes and, in my case, looks rather fugly. (4) See screenshot at: http://i.imgur.com/ie16K.jpg Now how can I tell Compiz to pin the osd-lyrics bar to the desktop below all other windows and not minimize it? I tried all sorts of window rules and exceptions, e.g. using "class=osd-lyrics", "title=osd-lyrics" but the OSD doesn't seem to match any of these. Any ideas? Running: Ubuntu 10.10 Maverick Meerkat, Compiz 0.8.6, osd-lyrics 0.3 from code.google.com/p/osd-lyrics

  • I can't get grub menu to show up during boot

    - by wim
    After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

  • Silverlight Developer needs ASP.NET MVC Training [on hold]

    - by Peet Brits
    With Silverlight on the way out, our company wants to embrace HTML5 and related technologies. Background: Our Silverlight project did everything from generating its own models (or data contracts), sending it over WCF, tracking changes, with a whole deal of back-end code to make the ride smoother, but often also cluttered and more complex. Most of the original developers for this project are gone, and we want to embrace something new for future projects. Having done this very useful MVC Jump Start course at Microsoft Virtual Academy, we are all fired up for the next project. The problem is that we have very little in-depth knowledge of all the many different components. The most important hereof is probably Entity Framework, and (for later) Web API. I suppose the best place to start is at the Microsoft ASP.NET websites. Are there any other suggestions for learning from more experienced developers? I am a senior developer, but my knowledge of ASP.NET MVC (and related) is very limited. PS: We have a project deadline at the end of this month.

  • Contractor - Mispaid again - Walked out

    - by MeshMan
    Hi all, I'm wondering whether or not I've done the right thing as a contractor. Basically I'm in to my 3rd month, and my current client messed up the payment in the first month, and I just found out that they are again late in paying me for my 2nd month. It wouldn't be so bad if I wasn't in a bit of a financial situation due to this being my first contract experience. But as a matter of principal, I walked out on them and will be telling them that I will not be going back in until they resolve the pay. Part of me feels as though this was not a very professional thing to do, but I also don't feel that it was very professional for them to mess my payments up, twice in a row. Did I make the right decision? I still want to work for these guys and enjoy the job, but I have a life to attend to that requires finances and I can't afford to keep getting messed up with pay like this. I attempted to phrase the question to be oriented around contractors behaviour around clients that mis-treat them, and as some of the answers that have been posted so far, it's a good discussion. The answers coming in are great around different subjective situations.

  • How do I write to an outer truecrypt volume when the inner volume protection prevents writng?

    - by con-f-use
    In a nutshell After some time using the outer volume of a hidden volume in Truecrypt I cannot write to the outer volume anymore. The protection of the inner volume always kicks in before. How do I fix this? Details I'm using truecrypt's two layered encryption of a USB stick. The outer container carries my semi-sensitive stuff while the inner hidden values has a bit more valuable information. I use both, the inner and outer volume regularly and that is part of the problem. Truecrypt can mount the outer volume for writing while protecting the inner. Usually the inner volume, when not protected this way (or mounted read-only) would be indistinguishable from free space. That is of course part of the plausible deniability scheme of truecrypt. At the beginning, everything worked as expected. I could copy and delete data to the outer volume as I pleased. Now it seams that I have written and deleted enough data to have filled the outer volume once. Despite the write protection Ubuntu tries now to write to the continuous "free space" that is the inner volume. It does that although enough other free space is on the outer volume. But on this free space there used to be data so its fragmented and the file system write prefers continuous space. The write on the continuous free space of the outer volume of course fails (with the error message in the picture above) as Truecrypt's inner-volume-protection kicks in. The Question I know this is expected behaviour, but is there a better way to write to the outer volume that does not attempt to write to the hidden free space at the end? The whole question could be more generally rephrased to: How do I control, where on a partition data is written in Ubuntu?

  • Toolset agnostic build server and Silverlight projects

    - by Marko Apfel
    Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\WebApplications\Microsoft.WebApplication.targets" /> And now Visual Studio Conversion Wizard welcomes my with this: Solution Regardless of which line I write – this conversion comes back again and again, if the line has another form than <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So it seems that there is no simple way to change this behaviour. Workaraound I must accept, that this line must be in the csproj and to run the build the toolset must be copied to the build server at the correct location. So go to your development machine where Visual Studio is installed and copy the folder “C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications” to your build server at the equivalent location.   Xmas wishes to Microsoft: Please provide technologies to let us developers bundle all needed stuff for a project in one developer tree. It should be possible that one checkout starts us up! No additional installations regardless whether it is a developing machine or dedicated build or continuous integration server. Silverlight is only one example, code analysis configurations could also be terrible and much more …

  • Useful WatiN Extension Methods

    - by Steve Wilkes
    I've been doing a fair amount of UI testing using WatiN recently – here’s some extension methods I've found useful. This checks if a WatiN TextField is actually a hidden field. WatiN makes no distinction between text and hidden inputs, so this can come in handy if you render an input sometimes as hidden and sometimes as a visible text field. Note that this doesn't check if an input is visible (I've got another extension method for that in a moment), it checks if it’s hidden. public static bool IsHiddenField(this TextField textField) { if (textField == null || !textField.Exists) { return false; } var textFieldType = textField.GetAttributeValue("type"); return (textFieldType != null) && textFieldType.ToLowerInvariant() == "hidden"; } The next method quickly sets the value of a text field to a given string. By default WatiN types the text you give it into a text field one character at a time which can be necessary if you have behaviour you want to test which is triggered by individual key presses, but which most of time is just painfully slow; this method dumps the text in in one go. Note that if it's not a hidden field then it gives it focus first; this helps trigger validation once the value has been set and focus moves elsewhere. public static void SetText(this TextField textField, string value) { if ((textField == null) || !textField.Exists) { return; } if (!textField.IsHiddenField()) { textField.Focus(); } textField.Value = value; } Finally, here's a method which checks if an Element is currently visible. It does so by walking up the DOM and checking for a Style.Display of 'none' on any element between the one on which the method is invoked, and any of its ancestors. public static bool IsElementVisible(this Element element) { if ((element == null) || !element.Exists) { return false; } while ((element != null) && element.Exists) { if (element.Style.Display.ToLowerInvariant().Contains("none")) { return false; } element = element.Parent; } return true; } Hope they come in handy

  • Correct way to inject dependencies in Business logic service?

    - by Sri Harsha Velicheti
    Currently the structure of my application is as below Web App -- WCF Service (just a facade) -- Business Logic Services -- Repository - Entity Framework Datacontext Now each of my Business logic service is dependent on more than 5 repositories ( I have interfaces defined for all the repos) and I am doing a Constructor injection right now(poor mans DI instead of using a proper IOC as it was determined that it would be a overkill for our project). Repositories have references to EF datacontexts. Now some of the methods in the Business logic service require only one of the 5 repositories, so If I need to call that method I would end up instantiating a Service which will instatiate all 5 repositories which is a waste. An example: public class SomeService : ISomeService { public(IFirstRepository repo1, ISecondRepository repo2, IThirdRepository repo3) {} // My DoSomething method depends only on repo1 and doesn't use repo2 and repo3 public DoSomething() { //uses repo1 to do some stuff, doesn't use repo2 and repo3 } public DoSomething2() { //uses repo2 and repo3 to do something, doesn't require repo1 } public DoSomething3() { //uses repo3 to do something, doesn't require repo1 and repo2 } } Now if my I have to use DoSomething method on SomeService I end up creating both IFirstRepository,ISecondRepository and IThirdRepository but using only IFirstRepository, now this is bugging me, I can seem to accept that I am un-necessarily creating repositories and not using them. Is this a correct design? Are there any better alternatives? Should I be looking at Lazy instantiation Lazy<T> ?

  • Matlab: Why is '1' + 1 == 50? [migrated]

    - by phi
    Matlab has weak dynamic typing, which is what causes this weird behaviour. What I do not understand is what exactly happens, as this result really surprises me. Edit: To clarify, what I'm describing is clearly a result of Matlab storing chars in ASCII-format, which was also mentioned in the comments. I'm more interested in the way Matlab handles its variables, and specifically, how and when it assigns a type/tag to the values. Thanks. '1' is a 1-by-1 matrix of chars in matlab and '123' is a 1-by-3 matrix of chars. As expected, 1 returns a 1-by-1 double. Now if I enter '1' + 1 I get 50 as a 1-by-1 double, and if I enter '123' + 1 I get a 1-by-3 double [ 50 51 52 ] Furthermore, if I type 'a' + 1 the result is 98 in a 1-by-1 double. I assume this has to do with how Matlab stores char-variables in ascii form, but how exactly is it handling these? Are the data actually unityped and tagged, or how does it work? Thanks.

  • How to implement isValid correctly?

    - by Songo
    I'm trying to provide a mechanism for validating my object like this: class SomeObject { private $_inputString; private $_errors=array(); public function __construct($inputString) { $this->_inputString = $inputString; } public function getErrors() { return $this->_errors; } public function isValid() { $isValid = preg_match("/Some regular expression here/", $this->_inputString); if($isValid==0){ $this->_errors[]= 'Error was found in the input'; } return $isValid==1; } } Then when I'm testing my code I'm doing it like this: $obj = new SomeObject('an INVALID input string'); $isValid = $obj->isValid(); $errors=$obj->getErrors(); $this->assertFalse($isValid); $this->assertNotEmpty($errors); Now the test passes correctly, but I noticed a design problem here. What if the user called $obj->getErrors() before calling $obj->isValid()? The test will fail because the user has to validate the object first before checking the error resulting from validation. I think this way the user depends on a sequence of action to work properly which I think is a bad thing because it exposes the internal behaviour of the class. How do I solve this problem? Should I tell the user explicitly to validate first? Where do I mention that? Should I change the way I validate? Is there a better solution for this? UPDATE: I'm still developing the class so changes are easy and renaming functions and refactoring them is possible.

  • Override methods should call base method?

    - by Trevor Pilley
    I'm just running NDepend against some code that I have written and one of the warnings is Overrides of Method() should call base.Method(). The places this occurs are where I have a base class which has virtual properties and methods with default behaviour but which can be overridden by a class which inherits from the base class and doesn't call the overridden method. For example, in the base class I have a property defined like this: protected virtual char CloseQuote { get { return '"'; } } And then in an inheriting class which uses a different close quote: protected override char CloseQuote { get { return ']'; } } Not all classes which inherit from the base class use different quote characters hence my initial design. The alternatives I thought of were have get/set properties in the base class with the defaults set in the constructor: protected BaseClass() { this.CloseQuote = '"'; } protected char CloseQuote { get; set; } public InheritingClass() { this.CloseQuote = ']'; } Or make the base class require the values as constructor args: protected BaseClass(char closeQuote, ...) { this.CloseQuote = '"'; } protected char CloseQuote { get; private set; } public InheritingClass() base (closeQuote: ']', ...) { } Should I use virtual in a scenario where the base implementation may be replaced instead of extended or should I opt for one of the alternatives I thought of? If so, which would be preferable and why?

  • Client-server application design issue

    - by user2547823
    I have a collection of clients on server's side. And there are some objects that need to work with that collection - adding and removing clients, sending message to them, updating connection settings and so on. They should perform these actions simultaneously, so mutex or another synchronization primitive is required. I want to share one instance of collection between these objects, but all of them require access to private fields of collection. I hope that code sample makes it more clear[C++]: class Collection { std::vector< Client* > clients; Mutex mLock; ... } class ClientNotifier { void sendMessage() { mLock.lock(); // loop over clients and send message to each of them } } class ConnectionSettingsUpdater { void changeSettings( const std::string& name ) { mLock.lock(); // if client with this name is inside collection, change its settings } } As you can see, all these classes require direct access to Collection's private fields. Can you give me an advice about how to implement such behaviour correctly, i.e. keeping Collection's interface simple without it knowing about its users?

  • How to setup users for desktop app with SQL Azure as backend?

    - by Manuel
    I'm considering SQL Azure as DB for a new application I'm developing. The reason I want to go with Azure is because I don't want to have to maintain yet another database(s) and I want my users to be able to access the data from anywhere. The problem is that I'm not clear regarding how to users will connect. The application is a basic CRUD type of windows app. I've read that you need to add your IP to SQL Azure's firewall to connect to it, but I don't know if it's only for administration purposes only. Can anyone clarify if anyone (anywhere) can access the data with the proper credentials? Which of the following scenarios would work best (if at all)? A) Add each user to SQL Azure and have the app connect directly to Azure as if it was connecting to SQL Server B) Add an anonymous user SQL Azure and pass the real user's password/hash with every call so the Azure database can service the requests accordingly. C) Put a WCF service in between so that it handles the authentication stuff. The service will only serve the appropriate information to the user given his/her authentication and SQL Azure would be open to the service exclusively. D) - ideas are welcomed - This is confusing because all Azure examples I see are for websites. I have a hard time believing SQL Azure wouldn't handle the case of desktop apps connecting to it. So what's the best practice?

  • Client/Server game even in solo: any big problem?

    - by Klaim
    I'm making a game which have strong basic design based on multiplayer but also should provide a really interesting and self-sufficient solo game. A bit like a real-time strategy game. The events and actions taken shouldn't be as massive and immediate as in a FPS, so you can also think the networking like for an RTS. It's a PC game, targetting Windows, MacOSX and Linux (Ubuntu & Fedora). It's programmed in C++, using a variety of open source libraries, so I have great (potential) control over the performances. So far I always considered that just making the game work with two applications, client & server, even in solo mode was ok. However, as I'm in the process of starting the network code I'm having doubts about if it's a good idea. I'm not a specialist so I might be missing something in my analysis. I see these pros and cons: Pros: The game works only one way so if I fix a bug it should apply on all game modes, whatever the distance with the server is; Basic networking issues would be detected early, including behaviour with the protection softwares (firewall) installed (i am not specialist so this might be wrong); Cons: I suppose that even if it should be really fast enough, networking client and server on the same computer would still be slower than no networking and message passing in (one) process memory. Maybe debugging would be more difficult? I don't have experience in this case but so far I assume that debugging with Visual Studio allows me to debug multiple process so it shouldn't be really different. Also, remote debugging. My question is: is there a big disadvantage that I missed? Or maybe there are advantages that I missed and that should encourage me to just continue with only client-server game sessions?

  • Career change: from programming into more human-oriented area [closed]

    - by Art
    I have been a software developer for approximately 9 years, starting with part-time work during my graduation year at uni. During these years I worked for number of companies, sometimes changing places twice or three times a year. They say it takes 10 years to reach 'expert' level, and while I don't think I am an expert by any measure and I have certainly met lots of people who are more knowledgeable, smarter and more focused than I am, I think I can safely say that I had my fair share of the whole programming trade and would like to move on to something else. Psychology and behaviour was always something I was interested in, especially the practical, applicable bits of it. Recently I've been to some communication skills training and I realised that I have been missing out on the great deal of fun stuff - how people work and communicate, especially in subconscious, non-verbal area. Currently I am thinking of making a career change - ideally to move somewhere my technical skill would still be beneficial in some shape or form, or at least could serve as a bridge while I am transitioning there, you know, the whole gradual, bit-by-bit approach versus swim-or-drown one. I would like to hear your thoughts on this matter and to learn from you what are the possible transitions I can take.

  • When is it too late to go back to coding from a management role? [closed]

    - by LeoLambrettra
    Problem solving keeps the mind sharp and if you are like me then it makes you happy. But what if you went from coding up to Team Lead and then to Project Manager? I have a team of 12 and on a good salary but lately have been thinking that the politics and admin tasks of being middle level management in an Investment Bank is not the right path to happiness. I used to be able to design and code as well as manage but lately it's all budgets, admin tasks and people problems. At 39 is it too late to go be a senior developer again? Basically - Team Lead in a flat structure with good people rocks. But if half your team is offshore then it loses something - There's a lot of politics in Project Management and so many meetings that even if you want to code you start letting your team down by missing deadlines and only suited for small units of work The coding skills haven't gone so to pick up WCF services it just takes a bit of reading and then playing around. I reckon I could switch to a Hedge Fund and go back to developing and be far happier and get more money. My 2 doubts though are 1. Mid life crisis in that I'd get bored with coding again 2. Or maybe I'd like it but there aren't many dev jobs for 40+ so I'd be throwing away a high level management role that took 7 years at thee one bank to get to0 Anybody else made to switch back and survived?

  • How to run sudo command with no password?

    - by aychedee
    tl;dr: How does the ubuntu user on the AWS images for Ubuntu Server 12.04 have passwordless sudo for all commands when there is no configuration for it in `/etc/sudoers'? I'm using Ubuntu server 12.04 on Amazon. I want to add a new user that has the same behaviour as the default ubuntu user. Specifically I want passwordless sudo for this new user. So I've added a new user and went to edit /etc/sudoers (using visudo of course). From reading that file it seemed like the default ubuntu user was getting it's passwordless sudo from being a member of the admin group. So I added my new user to that. Which didn't work. Then I tried adding the NOPASSWD directive to sudoers. Which also didn't work. Anyway, now I'm just curious. How does the ubuntu user get passwordless privileges if they aren't defined in /etc/sudoers. What is the mechanism that allows this?

  • Hello!

    - by barryoreilly
    After many months of deliberating I have finally gotten around to starting this blog! The reason for doing this is the large number of half finished articles lying around on my hard disk, unpublished and unloved. These articles have been of huge benefit to me, and have been written in an attempt to consolidate my own thinking, in order to help me structure my thoughts and ideas as I have tried to digest new ideas and understand abstract theories. It is my hope that by tidying up these articles and publishing them here that I can continue this learning process by getting feedback on the ideas from within the developer community. i have worked with .NET for 8 years now, and have worked with ASP.NET, SQL Server, Windows programming as well as general network administration. Since 2004 my focus has been on integration, web services, and more often than not Biztalk Server. The last two years have seen me focus on SOA and WCF, and the Managed Services Engine, so this is probably where the main focus of the blog will to start with, but there are so many fun things to play with these days that i have no idea where it will end up.....   Barry

  • Screen flickering / scrambling on an Asus UL30A

    - by user55059
    Recently my Laptop screen started to flicker. You can view the phenomena here: YouTube Sometimes the screen is totally scrambled, but most of the time it starts with the Title bar only. It happens inconsistently. My Laptop is Asus UL30A and I'm using Ubuntu 11.10. Output from command: sudo lshw -C display; lsb_release -a; uname -a; xrandr *-display:0 description: VGA compatible controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 07 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:fe400000-fe7fffff memory:d0000000-dfffffff ioport:dc00(size=8) *-display:1 UNCLAIMED description: Display controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2.1 bus info: pci@0000:00:02.1 version: 07 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: latency=0 resources: memory:fe800000-fe8fffff LSB Version: core-2.0-ia32:core-2.0-noarch:core-3.0-ia32:core-3.0-noarch:core-3.1-ia32:core-3.1-noarch:core-3.2-ia32:core-3.2-noarch:core-4.0-ia32:core-4.0-noarch Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric Linux steelke 3.0.0-14-generic-pae #23-Ubuntu SMP Mon Nov 21 22:07:10 UTC 2011 i686 i686 i386 GNU/Linux Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 293mm x 164mm 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) I already rolled back the kernel to 3.0.0-14 instead of 3.0.0-17 as mentioned in this post, but without result. I guess the problem is related to the driver, because I don't see similar behaviour in the BIOS Setup. Any tips or help is welcome.

  • Task-It Source Code

    Download Source Code I've received many questions about when the source code for the Task-It application will be released. Well, the time has finally come. I haven't been able to release this sooner due to the flurry of releases that have been coming out lately. Silverlight 4, WCF RIA Services, and even our Q1 Rad Controls. Each time I got the latest bits I ran into issues (either bugs or visual issues) in the Task-It that needed to be fixed. Having said that, the app is far from perfect. There are still some bugs lurking and things that need to be fixed up visually (especially the RadGridView filtering popup), but the main purpose of this app is to show the RadControls for Silverlight 4 in the context of a real-world application, and I don't want to keep delaying the release of the source code. Minimum requirements To run the app you will need the latest Silverlight bits. Silverlight 4 RTM, VS2010 and the ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How to leverage the internal HTTP endpoint available on Azure web roles?

    - by adelsors
    Imagine you have a Web application using an in-memory collection that changes occasionally, loading it from storage on the Application_Start global.asax event and updating it whenever it changes. If you want to deploy this application on Azure you need to keep in mind that more than one instance of the application can be running at any time and therefore you need to provide some mechanism to keep all instances informed with the latest changes. Because that the communication through internal endpoints between Azure role instances is at no cost, a good solution can be maintaining the information on Azure Storage Tables, reading its contents on the Application_Start event and populating its changes to all instances using the internal HTTP port available on Azure Web Roles. You need to follow these steps to leverage the internal HTTP endpoint available on Azure web roles: 1.   Define an internal HTTP endpoint in the Web Role properties, for example InternalHttpEndpoint   2.   Add a new WCF service to the Web Role, for example NotificationServices.svc 3.   Add a method on the new service to receive notifications from other role instances. 4.   Declare a class that inherits from System.ServiceModel.Activation.ServiceHostFactory and override the method CreateServiceHost to host the internal endpoint.   Note that you can use SecurityMode.None because the internal endpoint is private to the instances of the service, this is provided by the platform. 5.   Edit the markup of the service right clicking the svc file and selecting "View markup" to add the new factory as the factory to be used to create the service    6. Now you can notify changes to other instances using this code:
