• Apple File Sharing fails to connect

  - by Josh

  Running OSX Lion Server (10.7.4), and about once a week or so the Apple File Sharing service stops letting clients connect to its shares. On the client we will see a dialog box stating "There was a problem connecting to the server ". Browsing the server we simply no longer see the shares. The clients are also running the latest OSX (10.7.4) In /var/log/system.log we see entries like the following: Jun 26 08:38:22 w3 AppleFileServer[20511]: received message with invalid client_id 157 Jun 26 08:42:11 w3 AppleFileServer[20511]: received message with invalid client_id 165 Jun 26 08:42:21 w3 AppleFileServer[20511]: received message with invalid client_id 174 Where 20511 appears to be the pid, and client_id appears to be incremented with each failed attempt. Nothing jumps out at me from /Library/Logs/AppleFileService/AppleFileService[Access|Error].log Restarting the service fixes the problem: serveradmin stop afp && serveradmin start afp So I added a script to do this daily using the periodic service. But, we still encounter this problem about once a a week.

• I want to make video games, but I hate coding

  - by hoper

  I know this sounds eally crazy. However, I just want to ask. Now, I am studying C++ code in my school (My major is computer programming). Honestly, my grade is not so good, and assignments are really hard. Sometimes, I feel sad that I will spend 8~10 hours per day for coding (which is stressful) at the future for my job. But, I still want to make video games. Maybe this is the only one reason why I am taking all of stressful courses. I always write down plots, stories, characters, fictional gaming worlds. Once, I thought I should study artistic technology such as game design program not computer technology such as C++, C#, etc. However, most of popular game designers(or directors) such as Kojima, Miyamoto Shigeru, etc used to be good programmers. And, companies actaully assign programmers to directors because they understand how to make a game. I try to find other colleges or universities where teach game design program. However, one article that lists rank 10 game design schools in North America seems untrustful because the survey company only scores it from intervews of students. (Once, I tried to attend Art Institute of Vancouver which is rank 7 according to that article. However, one programmer who used to be an instructor in there told me the truth. That is the employement rate of graduated students is low) Do you guys have any advice for me?

• How many different servers are needed to keep a website running with no downtime? [closed]

  - by Mason Wheeler

  Machines go down. It's a fact of life. They may need to be rebooted for some reason, or they may have a hardware failure, or a power outage. So if I wanted to deploy a website with a server backed by a SQL database, putting the whole thing on one server wouldn't be good enough. It obviously needs at least two servers, so that if one goes down, the other can pick up the slack until the first comes back up. Of course, if I have the server software on two machines, either one of which could go down, I can't place the database on either of those two machines, because it could go down. So the database needs its own server. But that server can go down, so I need a backup database server and some sort of replication system to keep it in sync so the main can fail-over to it. So far, that's a bare minimum of 4 machines to keep one website running with a reasonable chance of no downtime. (Assuming no catastrophic events take place that take down both front-end servers at once or both DB servers at once, and no hacks, DDOS attacks, etc. Am I missing any other factors, or should I consider 4 servers to be the minimum for running a website with a goal of continuing operation without downtime even when a server goes down?

• How to hack airport extreme to support USB 3G modem?

  - by Mike Caron

  Has anyone out there ever tried to hack the Airport Extreme, specifically with regard to the USB port? There are many cellular routers available that provide WiFi sharing of a USB modem link. However, instead of buying yet another router, I'd like to use my expensive Airport Extreme with it. The AE has a USB port on the back, but it's been said that it only talks to printers. Is there a way to hack the USB driver on the AE to allow it to recognize a USB modem, then use that as the connectivity instead of the LAN? I would imagine that one could use OpenFirmware to boot something on the AE. If one can boot it, then one could provide access using SSH across the lan. Once access is granted, then let the hacking begin... but I don't know how to (a) get the mini-osx on to USB (is it the same as the ATV without a UI?) or (b) how to load up certain things once boot has begun.

• Not All “Viruses” Are Viruses: 10 Malware Terms Explained

  - by Chris Hoffman

  Most people seem to call every type of malware a “virus”, but that isn’t technically accurate. You’ve probably heard of many more terms beyond virus: malware, worm, Trojan, rootkit, keylogger, spyware, and more. But what do all these terms mean? These terms aren’t just used by geeks. They make their way into even mainstream news stories about the latest web security problems and tech scares. Understanding them will help you understand the dangers your\ hear about. Malware The word “malware” is short for “malicious software.” Many people use the word “virus” to indicate any type of harmful software, but a virus is actually just a specific type of malware. The word “malware” encompasses all harmful software, including all the ones listed below. Virus Let’s start with viruses. A virus is a type of malware that copies itself by infecting other files,  just as viruses in the real world infect biological cells and use those biological cells to reproduce copies of themselves. A virus can do many different things — watch in the background and steal your passwords, display advertisements, or just crash your computer — but the key thing that makes it a virus is how it spreads. When you run a virus, it will infect programs on your computer. When you run the program on another computer, the virus will infect programs on that computer, and so on. For example, a virus might infect program files on a USB stick. When the programs on that USB stick are run on another computer, the virus runs on the other computer and infects more program files. The virus will continue to spread in this way. Worm A worm is similar to a virus, but it spreads a different way. Rather than infecting files and relying on human activity to move those files around and run them on different systems, a worm spreads over computer networks on its own accord. For example, the Blaster and Sasser worms spread very quickly in the days of Windows XP because Windows XP did not come properly secured and exposed system services to the Internet. The worm accessed these system services over the Internet, exploited a vulnerability, and infected the computer. The worm then used the new infected computer to continue replicating itself. Such worms are less common now that Windows is properly firewalled by default, but worms can also spread in other ways — for example, by mass-emailing themselves to every email address in an effected user’s address book. Like a virus, a worm can do any number of other harmful things once it infects a computer. The key thing that makes it a worm is simply how it spreads copies of itself. Trojan (or Trojan Horse) A Trojan horse, or Trojan, is a type of malware that disguises itself as a legitimate file. When you download and run the program, the Trojan horse will run in the background, allowing third-parties to access your computer. Trojans can do this for any number of reasons — to monitor activity on your computer, to join your computer to a botnet. Trojans may also be used to open the floodgates and download many other types of malware onto your computer. The key thing that makes this type of malware a Trojan is how it arrives. It pretends to be a useful program and, when run, it hides in the background and gives malicious people access to your computer. It isn’t obsessed with copying itself into other files or spreading over the network, as viruses and worms are. For example, a piece of pirated software on an unscrupulous website may actually contain a Trojan. Spyware Spyware is a type of malicious software that spies on you without your knowledge. It collects a variety of different types of data, depending on the piece of spyware. Different types of malware can function as spyware — there may be malicious spyware included in Trojans that spies on your keystrokes to steal financial data, for example. More “legitimate” spyware may be bundled along with free software and simply monitor your web browsing habits, uploading this data to advertising servers so the software’s creator can make money from selling their knowledge of your activities. Adware Adware often comes along with spyware. It’s any type of software that displays advertising on your computer. Programs that display advertisements inside the program itself aren’t generally classified as malware. The kind of “adware” that’s particularly malicious is the kind that abuses its access to your system to display ads when it shouldn’t. For example, a piece of harmful adware may cause pop-up advertisements to appear on your computer when you’re not doing anything else. Or, adware may inject additional advertising into other web pages as you browse the web. Adware is often combined with spyware — a piece of malware may monitor your browsing habits and use them to serve you more targeted ads. Adware is more “socially acceptable” than other types of malware on Windows and you may see adware bundled with legitimate programs. For example, some people consider the Ask Toolbar included with Oracle’s Java software adware. Keylogger A keylogger is a type of malware that runs in the background, recording every key stroke you make. These keystrokes can include usernames, passwords, credit card numbers, and other sensitive data. The keylogger then, most likely, uploads these keystrokes to a malicious server, where it can be analyzed and people can pick out the useful passwords and credit card numbers. Other types of malware can act as keyloggers. A virus, worm, or Trojan may function as a keylogger, for example. Keyloggers may also be installed for monitoring purposes by businesses or even jealous spouses. Botnet, Bot A botnet is a large network of computers that are under the botnet creator’s control. Each computer functions as a “bot” because it’s infected with a specific piece of malware. Once the bot software infects the computer, ir will connect to some sort of control server and wait for instructions from the botnet’s creator. For example, a botnet may be used to initiate a DDoS (distributed denial of service) attack. Every computer in the botnet will be told to bombard a specific website or server with requests at once, and such millions or requests can cause a server to become unresponsive or crash. Botnet creators may sell access to their botnets, allowing other malicious individuals to use large botnets to do their dirty work. Rootkit A rootkit is a type of malware designed to burrow deep into your computer, avoiding detection by security programs and users. For example, a rootkit might load before most of Windows, burying itself deep into the system and modifying system functions so that security programs can’t detect it. A rootkit might hide itself completely, preventing itself from showing up in the Windows task manager. The key thing that makes a type of malware a rootkit is that it’s stealthy and focused on hiding itself once it arrives. Ransomware Ransomware is a fairly new type of malware. It holds your computer or files hostage and demands a ransom payment. Some ransomware may simply pop up a box asking for money before you can continue using your computer. Such prompts are easily defeated with antivirus software. More harmful malware like CryptoLocker literally encrypts your files and demands a payment before you can access them. Such types of malware are dangerous, especially if you don’t have backups. Most malware these days is produced for profit, and ransomware is a good example of that. Ransomware doesn’t want to crash your computer and delete your files just to cause you trouble. It wants to take something hostage and get a quick payment from you. So why is it called “antivirus software,” anyway? Well, most people continue to consider the word “virus” synonymous with malware as a whole. Antivirus software doesn’t just protect against viruses, but against all types of malware. It may be more accurately referred to as “antimalware” or “security” software.

• Jabber Breaks in Empathy

  - by Tim Lytle

  Using empathy in Ubuntu 10.04 (64 bit), everything worked great after initial setup. But after disconnecting and reconnecting, any Jabber connection (GTalk and Facebook Chat) gives a 'network error'. Tried disabling accounts and only connecting to GTalk, same error. Tried removing all accounts, adding GTalk, same error. Upgraded to the dev version of Empathy, connected once, then after going 'offline' and reconnecting, same error. If it just didn't work, I'd wait for some kind of fix. But it did work, but only once per install. How does that happen? Anyone with this problem that solved it?

• Move Files from a Failing PC with an Ubuntu Live CD

  - by Trevor Bekolay

  You’ve loaded the Ubuntu Live CD to salvage files from a failing system, but where do you store the recovered files? We’ll show you how to store them on external drives, drives on the same PC, a Windows home network, and other locations. We’ve shown you how to recover data like a forensics expert, but you can’t store recovered files back on your failed hard drive! There are lots of ways to transfer the files you access from an Ubuntu Live CD to a place that a stable Windows machine can access them. We’ll go through several methods, starting each section from the Ubuntu desktop – if you don’t yet have an Ubuntu Live CD, follow our guide to creating a bootable USB flash drive, and then our instructions for booting into Ubuntu. If your BIOS doesn’t let you boot using a USB flash drive, don’t worry, we’ve got you covered! Use a Healthy Hard Drive If your computer has more than one hard drive, or your hard drive is healthy and you’re in Ubuntu for non-recovery reasons, then accessing your hard drive is easy as pie, even if the hard drive is formatted for Windows. To access a hard drive, it must first be mounted. To mount a healthy hard drive, you just have to select it from the Places menu at the top-left of the screen. You will have to identify your hard drive by its size. Clicking on the appropriate hard drive mounts it, and opens it in a file browser. You can now move files to this hard drive by drag-and-drop or copy-and-paste, both of which are done the same way they’re done in Windows. Once a hard drive, or other external storage device, is mounted, it will show up in the /media directory. To see a list of currently mounted storage devices, navigate to /media by clicking on File System in a File Browser window, and then double-clicking on the media folder. Right now, our media folder contains links to the hard drive, which Ubuntu has assigned a terribly uninformative label, and the PLoP Boot Manager CD that is currently in the CD-ROM drive. Connect a USB Hard Drive or Flash Drive An external USB hard drive gives you the advantage of portability, and is still large enough to store an entire hard disk dump, if need be. Flash drives are also very quick and easy to connect, though they are limited in how much they can store. When you plug a USB hard drive or flash drive in, Ubuntu should automatically detect it and mount it. It may even open it in a File Browser automatically. Since it’s been mounted, you will also see it show up on the desktop, and in the /media folder. Once it’s been mounted, you can access it and store files on it like you would any other folder in Ubuntu. If, for whatever reason, it doesn’t mount automatically, click on Places in the top-left of your screen and select your USB device. If it does not show up in the Places list, then you may need to format your USB drive. To properly remove the USB drive when you’re done moving files, right click on the desktop icon or the folder in /media and select Safely Remove Drive. If you’re not given that option, then Eject or Unmount will effectively do the same thing. Connect to a Windows PC on your Local Network If you have another PC or a laptop connected through the same router (wired or wireless) then you can transfer files over the network relatively quickly. To do this, we will share one or more folders from the machine booted up with the Ubuntu Live CD over the network, letting our Windows PC grab the files contained in that folder. As an example, we’re going to share a folder on the desktop called ToShare. Right-click on the folder you want to share, and click Sharing Options. A Folder Sharing window will pop up. Check the box labeled Share this folder. A window will pop up about the sharing service. Click the Install service button. Some files will be downloaded, and then installed. When they’re done installing, you’ll be appropriately notified. You will be prompted to restart your session. Don’t worry, this won’t actually log you out, so go ahead and press the Restart session button. The Folder Sharing window returns, with Share this folder now checked. Edit the Share name if you’d like, and add checkmarks in the two checkboxes below the text fields. Click Create Share. Nautilus will ask your permission to add some permissions to the folder you want to share. Allow it to Add the permissions automatically. The folder is now shared, as evidenced by the new arrows above the folder’s icon. At this point, you are done with the Ubuntu machine. Head to your Windows PC, and open up Windows Explorer. Click on Network in the list on the left, and you should see a machine called UBUNTU in the right pane. Note: This example is shown in Windows 7; the same steps should work for Windows XP and Vista, but we have not tested them. Double-click on UBUNTU, and you will see the folder you shared earlier! As well as any other folders you’ve shared from Ubuntu. Double click on the folder you want to access, and from there, you can move the files from the machine booted with Ubuntu to your Windows PC. Upload to an Online Service There are many services online that will allow you to upload files, either temporarily or permanently. As long as you aren’t transferring an entire hard drive, these services should allow you to transfer your important files from the Ubuntu environment to any other machine with Internet access. We recommend compressing the files that you want to move, both to save a little bit of bandwidth, and to save time clicking on files, as uploading a single file will be much less work than a ton of little files. To compress one or more files or folders, select them, and then right-click on one of the members of the group. Click Compress…. Give the compressed file a suitable name, and then select a compression format. We’re using .zip because we can open it anywhere, and the compression rate is acceptable. Click Create and the compressed file will show up in the location selected in the Compress window. Dropbox If you have a Dropbox account, then you can easily upload files from the Ubuntu environment to Dropbox. There is no explicit limit on the size of file that can be uploaded to Dropbox, though a free account begins with a total limit of 2 GB of files in total. Access your account through Firefox, which can be opened by clicking on the Firefox logo to the right of the System menu at the top of the screen. Once into your account, press the Upload button on top of the main file list. Because Flash is not installed in the Live CD environment, you will have to switch to the basic uploader. Click Browse…find your compressed file, and then click Upload file. Depending on the size of the file, this could take some time. However, once the file has been uploaded, it should show up on any computer connected through Dropbox in a matter of minutes. Google Docs Google Docs allows the upload of any type of file – making it an ideal place to upload files that we want to access from another computer. While your total allocation of space varies (mine is around 7.5 GB), there is a per-file maximum of 1 GB. Log into Google Docs, and click on the Upload button at the top left of the page. Click Select files to upload and select your compressed file. For safety’s sake, uncheck the checkbox concerning converting files to Google Docs format, and then click Start upload. Go Online – Through FTP If you have access to an FTP server – perhaps through your web hosting company, or you’ve set up an FTP server on a different machine – you can easily access the FTP server in Ubuntu and transfer files. Just make sure you don’t go over your quota if you have one. You will need to know the address of the FTP server, as well as the login information. Click on Places > Connect to Server… Choose the FTP (with login) Service type, and fill in your information. Adding a bookmark is optional, but recommended. You will be asked for your password. You can choose to remember it until you logout, or indefinitely. You can now browse your FTP server just like any other folder. Drop files into the FTP server and you can retrieve them from any computer with an Internet connection and an FTP client. Conclusion While at first the Ubuntu Live CD environment may seem claustrophobic, it has a wealth of options for connecting to peripheral devices, local computers, and machines on the Internet – and this article has only scratched the surface. Whatever the storage medium, Ubuntu’s got an interface for it!

• why does chkdsk always report errors on a bad shutdown

  - by rep_movsd

  Once in a while, Windows XP hangs on my laptop (usually when going into standby or hibernate and occasionally on startup) and I have to forcefully poweroff. Ususally chkdsk never runs automatically (I thought it should know that the partitions have nit been unmounted and do that). I religiously run chkdsk without /F after bad shutdowns like this, and invariably it reports that the drive has unfixed errors and must be checked with /F and I do that, and more often than not, the chdsk that runs on startup does not report fixing anything. I have had times in the past (and not only just on this system) when not running chkdsk leads to some strange errors like files not opening even though they exist and inability to save certain files, so I make it a point to always chkdsk after bad shutdown. I never understood why this is : Isnt the whole point of a journalling filesystem like NTFS to avoid file system corruption and endless chkdsks? I even tried once disabling write caching to see if it made any difference, but to no avail....

• Could not load type System.Configuration.NameValueSectionHandler

  If you upgrade older .NET sites from 1.x to 2.x or greater, you may encounter this error when you have configuration settings that look like this: <section name="CacheSettings" type="System.Configuration.NameValueFileSectionHandler, System"/> Once you try to run this on an upgraded appdomain, you may encounter this error: An error occurred creating the configuration section handler for CacheSettings: Could not load type 'System.Configuration.NameValueSectionHandler' from assembly 'System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Microsoft moved a bunch of the Configuration related classes into a separate assembly, System.Configuration, and created a new class, ConfigurationManager.  This presents its own challenges which Ive blogged about in the past if you are wondering where ConfigurationManager is located.  However, the above error is separate. The issue in this case is that the NameValueSectionHandler is still in the System assembly, but is in the System.Configuration namespace.  This causes confusion which can be alleviated by using the following section definition: <section name="CacheSettings" type="System.Configuration.NameValueSectionHandler, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> (you can remove the extra line breaks within the type=) With this in place, your web application should once more be able to load up the NameValueSectionHandler.  I do recommend using your own custom configuration section handlers instead of appSettings, and I would further suggest that you not use NamveValueSectionHandler if you can avoid it, but instead prefer a strongly typed configuration section handler.

• Add a custom certificate authority to Ubuntu

  - by rmrobins

  Hello; I have created a custom root certificate authority for an internal network, example.com. Ideally, I would like to be able to deploy the CA certificate associated with this certificate authority to my Linux clients (running Ubuntu 9.04 and CentOS 5.3), such that all of the applications automatically recognize the certificate authority (i.e. I do not want to have to configure Firefox, Thunderbird, etc manually to trust this certificate authority). I have attempted this on Ubuntu by copying the PEM-encoded CA certificate to /etc/ssl/certs/ and /usr/share/ca-certificates/, as well as by modifying /etc/ca-certificates.conf and rerunning update-ca-certificates, however applications do not seem to recognize that I have added another trusted CA to the system. Therefore, is it possible to add a CA certificate once to a system, or is it necessary to manually add the CA to all of the possible applications that will attempt to make SSL connections to hosts signed by this CA in my network? If it is possible to add a CA certificate once to the system, where does it need to go? Thanks.

• Reminder: True WCF Asynchronous Operation

  - by Sean Feldman

  A true asynchronous service operation is not the one that returns void, but the one that is marked as IsOneWay=true using BeginX/EndX asynchronous operations (thanks Krzysztof). To support this sort of fire-and-forget invocation, Windows Communication Foundation offers one-way operations. After the client issues the call, Windows Communication Foundation generates a request message, but no correlated reply message will ever return to the client. As a result, one-way operations can't return values, and any exception thrown on the service side will not make its way to the client. One-way calls do not equate to asynchronous calls. When one-way calls reach the service, they may not be dispatched all at once and may be queued up on the service side to be dispatched one at a time, all according to the service configured concurrency mode behavior and session mode. How many messages (whether one-way or request-reply) the service is willing to queue up is a product of the configured channel and the reliability mode. If the number of queued messages has exceeded the queue's capacity, then the client will block, even when issuing a one-way call. However, once the call is queued, the client is unblocked and can continue executing while the service processes the operation in the background. This usually gives the appearance of asynchronous calls.

• Unable to access local network when Cisco VPN client is connected

  - by bryanroth

  I'm a developer and don't have much networking expertise, so bear with me. I'm using the Cisco VPN Client 5.0.02.0090 to connect to my work's VPN that way I can RDP into my work computer. Once connected, I can't ping anything on the local network once connected to the VPN thus I am unable to access my work's network. This used to work about two weeks ago but abruptly stopped working today. However, I have the Cisco VPN Client installed on my laptop and I am able to ping and RDP into my work computer from there. Both my desktop and laptop computers are connected to the same router at home. I have tried the following so far: Rebooted my computer Reinstalled VPN client Updated NIC drivers Disabled firewall Opened up ports 500, 4500, and 10000 Any help would be much appreciated. Thanks!

• Perforce Restore From Multiple Checkpoint Files?

  - by AJ

  Hi all, I am working with a very large (~11GB) checkpoint file and trying to do a -jr (journal restore) operation. About half way through the file, I'm hitting an entry which causes an error to occur. I'm unable to come up with a conventional way to print, edit, and save changes to the offending line. So right now I'm splitting the checkpoint into files of 500k lines each...up to 47 files and counting. My question is, once I have these separate files: Can I run journal restore on each one separately to check for errors? Once fixed, is it necessary to merge them back together again to do my full journal restore? Any other ideas on how to tackle this problem would be appreciated. Thanks in advance, -aj

• Connecting Visual Studio 2008 SP1 to TFS 2010

  - by Enrique Lima

  Introduction You have installed Team Foundation Server 2010, you are ready to go.  Your client is Visual Studio 2008 SP1, and need to connect to TFS 2010. Here is the story, the steps to configure Team Explorer are almost the same … meaning, you will open Visual Studio, then go to Team Explorer.  At that point you will Add an Existing Project, this where we connect to TFS.  Except, we get this: Now what?!?  We need to install the Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010.  Where to get it from? TFS 2010 installation media Microsoft’s Download Center Update Installation We arrive at the Welcome Screen for the Update, click Next Next comes the license screen, accept the license, by selecting the checkbox, then click next. The installation process will start at that point. Once it completes, click on Finish. Second Try Time to attempt to connect again. We are back to working with Team Explorer, and Adding an existing project.  There is a formula to be successful with this. protocol://servername:port/tfs/<name of collection> protocol = http or https servername = your tfs 2010 server port = 8080 by default, or the custom port you are using /tfs = I am assuming the default too /<name of collection = the name of the collection that was provisioned. Once the values are provided, click OK, then close. At this point you should see a listing of Projects available within the TFS 2010 collection. Select the project and click OK.  You will now see this listed in Team Explorer.

• Adding an Admin user to an ASP.NET MVC 4 application using a single drop-in file

  - by Jon Galloway

  I'm working on an ASP.NET MVC 4 tutorial and wanted to set it up so just dropping a file in App_Start would create a user named "Owner" and assign them to the "Administrator" role (more explanation at the end if you're interested). There are reasons why this wouldn't fit into most application scenarios: It's not efficient, as it checks for (and creates, if necessary) the user every time the app starts up The username, password, and role name are hardcoded in the app (although they could be pulled from config) Automatically creating an administrative account in code (without user interaction) could lead to obvious security issues if the user isn't informed However, with some modifications it might be more broadly useful - e.g. creating a test user with limited privileges, ensuring a required account isn't accidentally deleted, or - as in my case - setting up an account for demonstration or tutorial purposes. Challenge #1: Running on startup without requiring the user to install or configure anything I wanted to see if this could be done just by having the user drop a file into the App_Start folder and go. No copying code into Global.asax.cs, no installing addition NuGet packages, etc. That may not be the best approach - perhaps a NuGet package with a dependency on WebActivator would be better - but I wanted to see if this was possible and see if it offered the best experience. Fortunately ASP.NET 4 and later provide a PreApplicationStartMethod attribute which allows you to register a method which will run when the application starts up. You drop this attribute in your application and give it two parameters: a method name and the type that contains it. I created a static class named PreApplicationTasks with a static method named, then dropped this attribute in it: [assembly: PreApplicationStartMethod(typeof(PreApplicationTasks), "Initializer")] That's it. One small gotcha: the namespace can be a problem with assembly attributes. I decided my class didn't need a namespace. Challenge #2: Only one PreApplicationStartMethod per assembly In .NET 4, the PreApplicationStartMethod is marked as AllMultiple=false, so you can only have one PreApplicationStartMethod per assembly. This was fixed in .NET 4.5, as noted by Jon Skeet, so you can have as many PreApplicationStartMethods as you want (allowing you to keep your users waiting for the application to start indefinitely!). The WebActivator NuGet package solves the multiple instance problem if you're in .NET 4 - it registers as a PreApplicationStartMethod, then calls any methods you've indicated using [assembly: WebActivator.PreApplicationStartMethod(type, method)]. David Ebbo blogged about that here:  Light up your NuGets with startup code and WebActivator. In my scenario (bootstrapping a beginner level tutorial) I decided not to worry about this and stick with PreApplicationStartMethod. Challenge #3: PreApplicationStartMethod kicks in before configuration has been read This is by design, as Phil explains. It allows you to make changes that need to happen very early in the pipeline, well before Application_Start. That's fine in some cases, but it caused me problems when trying to add users, since the Membership Provider configuration hadn't yet been read - I got an exception stating that "Default Membership Provider could not be found." The solution here is to run code that requires configuration in a PostApplicationStart method. But how to do that? Challenge #4: Getting PostApplicationStartMethod without requiring WebActivator The WebActivator NuGet package, among other things, provides a PostApplicationStartMethod attribute. That's generally how I'd recommend running code that needs to happen after Application_Start: [assembly: WebActivator.PostApplicationStartMethod(typeof(TestLibrary.MyStartupCode), "CallMeAfterAppStart")] This works well, but I wanted to see if this would be possible without WebActivator. Hmm. Well, wait a minute - WebActivator works in .NET 4, so clearly it's registering and calling PostApplicationStartup tasks somehow. Off to the source code! Sure enough, there's even a handy comment in ActivationManager.cs which shows where PostApplicationStartup tasks are being registered: public static void Run() { if (!_hasInited) { RunPreStartMethods(); // Register our module to handle any Post Start methods. But outside of ASP.NET, just run them now if (HostingEnvironment.IsHosted) { Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility.RegisterModule(typeof(StartMethodCallingModule)); } else { RunPostStartMethods(); } _hasInited = true; } } Excellent. Hey, that DynamicModuleUtility seems familiar... Sure enough, K. Scott Allen mentioned it on his blog last year. This is really slick - a PreApplicationStartMethod can register a new HttpModule in code. Modules are run right after application startup, so that's a perfect time to do any startup stuff that requires configuration to be read. As K. Scott says, it's this easy: using System; using System.Web; using Microsoft.Web.Infrastructure.DynamicModuleHelper; [assembly:PreApplicationStartMethod(typeof(MyAppStart), "Start")] public class CoolModule : IHttpModule { // implementation not important // imagine something cool here } public static class MyAppStart { public static void Start() { DynamicModuleUtility.RegisterModule(typeof(CoolModule)); } } Challenge #5: Cooperating with SimpleMembership The ASP.NET MVC Internet template includes SimpleMembership. SimpleMembership is a big improvement over traditional ASP.NET Membership. For one thing, rather than forcing a database schema, it can work with your database schema. In the MVC 4 Internet template case, it uses Entity Framework Code First to define the user model. SimpleMembership bootstrap includes a call to InitializeDatabaseConnection, and I want to play nice with that. There's a new [InitializeSimpleMembership] attribute on the AccountController, which calls \Filters\InitializeSimpleMembershipAttribute.cs::OnActionExecuting(). That comment in that method that says "Ensure ASP.NET Simple Membership is initialized only once per app start" which sounds like good advice. I figured the best thing would be to call that directly: new Mvc4SampleApplication.Filters.InitializeSimpleMembershipAttribute().OnActionExecuting(null); I'm not 100% happy with this - in fact, it's my least favorite part of this solution. There are two problems - first, directly calling a method on a filter, while legal, seems odd. Worse, though, the Filter lives in the application's namespace, which means that this code no longer works well as a generic drop-in. The simplest workaround would be to duplicate the relevant SimpleMembership initialization code into my startup code, but I'd rather not. I'm interested in your suggestions here. Challenge #6: Module Init methods are called more than once When debugging, I noticed (and remembered) that the Init method may be called more than once per page request - it's run once per instance in the app pool, and an individual page request can cause multiple resource requests to the server. While SimpleMembership does have internal checks to prevent duplicate user or role entries, I'd rather not cause or handle those exceptions. So here's the standard single-use lock in the Module's init method: void IHttpModule.Init(HttpApplication context) { lock (lockObject) { if (!initialized) { //Do stuff } initialized = true; } } Putting it all together With all of that out of the way, here's the code I came up with: using Mvc4SampleApplication.Filters; using System.Web; using System.Web.Security; using WebMatrix.WebData; [assembly: PreApplicationStartMethod(typeof(PreApplicationTasks), "Initializer")] public static class PreApplicationTasks { public static void Initializer() { Microsoft.Web.Infrastructure.DynamicModuleHelper.DynamicModuleUtility .RegisterModule(typeof(UserInitializationModule)); } } public class UserInitializationModule : IHttpModule { private static bool initialized; private static object lockObject = new object(); private const string _username = "Owner"; private const string _password = "p@ssword123"; private const string _role = "Administrator"; void IHttpModule.Init(HttpApplication context) { lock (lockObject) { if (!initialized) { new InitializeSimpleMembershipAttribute().OnActionExecuting(null); if (!WebSecurity.UserExists(_username)) WebSecurity.CreateUserAndAccount(_username, _password); if (!Roles.RoleExists(_role)) Roles.CreateRole(_role); if (!Roles.IsUserInRole(_username, _role)) Roles.AddUserToRole(_username, _role); } initialized = true; } } void IHttpModule.Dispose() { } } The Verdict: Is this a good thing? Maybe. I think you'll agree that the journey was undoubtedly worthwhile, as it took us through some of the finer points of hooking into application startup, integrating with membership, and understanding why the WebActivator NuGet package is so useful Will I use this in the tutorial? I'm leaning towards no - I think a NuGet package with a dependency on WebActivator might work better: It's a little more clear what's going on Installing a NuGet package might be a little less error prone than copying a file A novice user could uninstall the package when complete It's a good introduction to NuGet, which is a good thing for beginners to see This code either requires either duplicating a little code from that filter or modifying the file to use the namespace Honestly I'm undecided at this point, but I'm glad that I can weigh the options. If you're interested: Why are you doing this? I'm updating the MVC Music Store tutorial to ASP.NET MVC 4, taking advantage of a lot of new ASP.NET MVC 4 features and trying to simplify areas that are giving people trouble. One change that addresses both needs us using the new OAuth support for membership as much as possible - it's a great new feature from an application perspective, and we get a fair amount of beginners struggling with setting up membership on a variety of database and development setups, which is a distraction from the focus of the tutorial - learning ASP.NET MVC. Side note: Thanks to some great help from Rick Anderson, we had a draft of the tutorial that was looking pretty good earlier this summer, but there were enough changes in ASP.NET MVC 4 all the way up to RTM that there's still some work to be done. It's high priority and should be out very soon. The one issue I ran into with OAuth is that we still need an Administrative user who can edit the store's inventory. I thought about a number of solutions for that - making the first user to register the admin, or the first user to use the username "Administrator" is assigned to the Administrator role - but they both ended up requiring extra code; also, I worried that people would use that code without understanding it or thinking about whether it was a good fit.
