• Replacing local home server with VPS: Suggestions?

  - by CamronBute

  So right now, I'm running an old box with a 2TB HDD in it. I use this as a file server for the home network, as well as a box for downloading large files which are synced via Dropbox. Lots of other tinkering things, too. Basically, I'm sick of paying extra for the power and having to worry about drive failures and whatnot. I'd rather get a remote server, let someone else manage it and provide access from the Internet. So, I've been looking for a Windows VPS that would give me access to install things and tinker, and I'm having a problem finding a host that offers more than 100GB of hard drive space. If they do offer a package with 100GB of storage, everything else is waaayyyy more than what I actually need. The idea is to create a permanent VPN connection from the cloud server to my home network to provide a transparent solution so I'm not having to go to lengths to transfer files or whatnot. I think a VPS solution will allow me to do this. I would like 1TB of storage space, minimum 100Mbps Internet connection, minimum 250GB bandwidth, admin access. Anyone have anything? Or am I being unreasonable? If I am, why?

• Archive software for big files and fast index

  - by AkiRoss

  I'm currently using tar for archiving some files. Problem is: archives are pretty big, contains many data and tar is very slow when listing and extracting. I often need to extract single files or folders from the archive, but I don't currently have an external index of files. So, is there an alternative for Linux, allowing me to build uncompressed archive files, preserving the file attributes AND having fast access list table? I'm talking about archives of 10 to 100 GB, and it's pretty impractical to wait several minutes to access a single file. Anyway, any trick to solve this problem is welcome (but single archives are non-optional, so no rsync or similar). Thanks in advance! EDIT: I'm not compressing archives, and using tar I think they are too slow. To be precise about "slow", I'd like that: listing archive content should take time linear in files count inside the archive, but with very little constant (e.g. if a list of all the files is included at the head of the archive, it could be very fast). extraction of a target file/directory should (filesystem premitting) take time linear with the target size (e.g. if I'm extracting a 2MB PDF file in a 40GB directory, I'd really like it to take less than few minutes... If not seconds). Of course, this is just my idea and not a requirement. I guess such performances could be achievable if the archive contained an index of all the files with respective offset and such index is well organized (e.g. tree structure).

• Powershell script to delete sub folders and files if creation date is >7 days but maintain parent folders of sub folders and files <7 days old

  - by Mark

  I'm currently using the Powershell script below to delete all files directories and sub directories of "$dump_path" that are seven days or older based upon the creation date and not modified date. The problem with this script is this: If folder "A" is seven (or more) days old it will be deleted even if its sub folders and files are less then seven days old. What I would like this script to do is this: Delete all files from the root and in all sub folders of "$dump_path" that are seven or more days old but maintain the parent folder(s) of files and folders that are less than seven days old even if that means the parent folders are more than seven days old. If all subfolders and files are seven days or older than the parent folder then the parent can be deleted. Slightly obscure problem I know, but the intention is to have a 7 day retention period of all data in a 'sandbox' location of our shared areas. Also, an added bonus if it could generate a log of what it deletes and e-mails it out post deletion. Thank you for reading and I hope that all makes sense! Mark # set folder path $dump_path = "c:\temp" # set minimum age of files and folders $max_days = "-7" # get the current date $curr_date = Get-Date # determine how far back we go based on current date $del_date = $curr_date.AddDays($max_days) # delete the files and folders Get-ChildItem $dump_path | Where-Object { $_.CreationTime -lt $del_date } | Remove-Item -Recurse

• how to properly set environment variables

  - by avorum

  I've recently started using Windows (having used Ubuntu up until now) and I find myself unable to properly set environment variables. Whenever I set them they don't seem to work. I've been going to Start-Edit Environment Variables for your Account and editing the PATH value in the upper half of the GUI. Here's what I've got so far. ;C:\Chocolatey\bin;C:\tools\mysql\current\bin;C:\Program Files (x86)\Git\bin;C:\Program Files\MySQL\MySQL Server 5.6\bin\;C:\Python33\Scripts; These are each the parent directories of the executables I'd like to be able to run by name from CMD, but mysql, git, and pip aren't being recognized. Am I doing something wrong syntactically or at a general understanding level? I'd like to be able to run these commands without having to specify the full path to the executables every time. EDIT: The full PATH extracted from CMD PATH=C:\Python33\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\Java\jre7\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft SDKs\TypeScript\;C:\Program Files (x86)\MySQL\MySQL Utilities 1.3.4\; ;C:\Chocolatey\bin;C:\tools\mysql\current\bin I'm being forced to use Windows by my work environment, I don't enjoy the state of affairs.

• Identify differences between MP3 files

  - by Thingomy

  I have 2 old similar directory trees with MP3 files in them. I am happily using tools like diff and Rsync to identify and merge the files that are only present on one side, or are identical, I'm left with a bunch of files that are bitwise different. On running diff over a pair actually different files, (with -a tag to force text analysis) it produces incomprehensible gibberish. I have listened to files from both sides, and they both seem to play fine (but at nearly 10 minutes per song, when listening to them twice each, I haven't done many) I suspect the differences are due to some player in the past "enhancing" my collection by messing about with ID3 tags, but I can't be certain. Even if I identify differences in ID3 tags, I would like to confirm that no cosmic ray or file copy error issues have damaged any of the files. One method that occurs to be is finding the byte locations of the differences, and ignoring all changes in the first ~10kb of each file, but I don't know how to do this. I have on the order of a hundred or so files that differ across the directory tree. I found How to compare mp3, flac audio data in a file, ignoring header data (ID3 tag) etc.? -- but I can't run alldup due to being Linux only, and from the sounds of it, it would only partially solve my issues anyway.

• Effective backup and archive strategy for database and linked files

  - by busyspin

  I am using Postgres to store a variety of application data for a webapp. Part of the application involves storing and retrieving user uploaded files. I am storing the files in the filesystem with some associated metadata in the database. I am trying to come up with a backup and archive strategy so that I can effectively backup and archive/restore the database and the linked files. Here are the things I want to accomplish. Perform routine backups that can be used for recovery from failures and which include all DB data and the linked files. Ideally, this backup would be done while the app is running. Live backup is certainly possible with a DB but I am not sure how to keep the linked files consistent with the database during the backup process Archive chunks of data as they become "old". These chunks must includes the database data plus any linked files. It should be possible to put the archived data back into production again. It would be ideal if it were easy to determine which ranges of objects were stored in each chunk. Do you have any advice for how to accomplish these goals? If the files were in the database as BLOBS these tasks would be much easier since normal database backup and restore functionality would handle this. I am not sure how to accomplish the same thing when file data is linked to database rows.

• Cannot open files in Visual Studio but in Delphi and Notepad

  - by Andrew J. Brehm

  About an hour ago Visual Studio 2008 decided that it cannot find files any more. This is on 64 bit Windows Vista. When I right-click on a text file (source code or otherwise) and select "open with" and "Visual Studio 2008", I get the following error (example): Windows cannot find 'C:\Users\ajbrehm\Documents\Visual Studio 2008\Projects\Hello Prism\Hello Prism\Main.pas'. Make sure you typed the name correctly, and then try again. When I right-click the same file and select "open with" and "Delphi 2010" or "Notepad" (both other options available for text files on my system), the file opens correctly. Oddly enough when the file is part of a Visual Studio project and I open the project itself with Visual Studio (this works), I can open the file from within Visual Studio. Any ideas what might be going on? This started about an hour after I made a complete backup of my Vista VM and after I installed IIS 7, SQL Express, and Sourcegear Vault. The first files I noticed couldn't be opened in Visual Studio any more where Pascal source files in checked-outed folders from Vault. And Vault also seems to be unable to see one of the sources files and claims they don't exist. I found out about Visual Studio not opening ANY files any more when I tried to recreate the file Vault refused to see. Update: I just checked. Another user, "administrator", can still open text files with Visual Studio 2008. Both users have administrator rights. Update: I just restored the hours-old backup. Same problem. Apparently whatever triggered this happened before the install of IIS 7 and SQL Express. Never noticed it before.

• How to access remote network resource from local machine

  - by jerluc

  I just configured VPN access successfully so that I now can connect to my workstation at work from my personal Linux box at home. The problem is that all of my dev files for a server I'm locally running are on my personal box and cannot be transfered to my workstation (at least not in any timely manner over this connection given the amount of data, in addition to the many reconfigurations which would be required for the server to run even if I could somehow get the files across). So essentially, I am able to run my server locally on my personal computer, however, the data-sources required for the back-end are accessible only from within the office's network. But is there some way for me to somehow either access the data-sources directly through a VPN connection or even if I need to be a bit more convoluted by connecting via VPN to my workstation and then somehow connecting to the data-sources through my workstation to my personal computer? And here I could really care less about the speed of the connection from my server to the data-sources since they will probably only be fetched a few times every hour or so. Thanks! Sorry if this a stupid question and/or doesn't make any sense! (And sorry for anyone who read this at stackoverflow, I posted it in the wrong area.)

• Slow Local Network, Windows 7, Snow Leopard, WiFi/Wired

  - by WerkkreW

  Hello - I am experiencing really poor local network performance in my home. I was recently using a Linksys WRT54G Router with DD-WRT on it, and a couple comparable Linksys-G PCI cards for connectivity but decided to upgrade hoping it would help with my performance issues. The computers in my house are connected as follows: Comcast Business Class Commercial 25mbps/10mbps (Verified with SpeakEasy and Speedtest.net) D-Link DGL-4500 Wireless N Router Windows 7x64 - D-Link DWA-552 Wireless-N Windows 7x64 - D-Link DWA-552 Wireless-N Mac Mini 10.6.2 - AirPort Extreme N Playstation 3, Hard Wired Xbox 360, Hard Wired Essentially the problem is very specific. Web browsing and uploading/downloading files from the internet is fine, more than fine. But if I want to say, Stream a video from one of my Windows 7 computers to my PS3, or copy a large video file between either of the PC's or the Mac, I get a consistent 500-900Kbps throughput at the high end. If I open my network browser, or try to browse my homegroup the response time is horrible. Both of my Windows computers are showing Strong wireless signals with a connection speed of 300Mbps. I know I can never expect to achieve anything near those speeds, but 500Kbps? Here is what I have tried so far: Enabled Single mode N-only and N/G Only on router WPA2 with AES Encrpytion Disabled "Remote Differential Compression" in Windows 7 Disabled TCP "Auto-Tuning" Used other software for file copies such as "Teracopy" I am at the end of my rope. Unfortunately I live in a 75 year old home with plaster walls, so hard-wiring my entire house isn't really an option I can handle right now. Any ideas to help me get decent speed when transferring files across my network would be greatly appreciated.

• Setting the default permissions for files uploaded via FTP to a directory

  - by Kerri

  Disclaimer: I'm just a web designer/coder, and server admin stuff is my weakest point of them all. So be easy on me (and very specific). I'm using a simple CMS (Unify) on a site, where part of the functionality is that the client can upload files to a specified directory (using FTP). The permissions for the upload directory are set to 755. But when files are uploaded through the interface, they are uploaded with permissions set to 640 (instead of 644), so site visitors cannot acces the files. When I emailed the CMS's support about this, they told me that it was a server setting, and I need to make sure that files uploaded through FTP are set to 644. Makes perfect sense, but I have no idea how to do this. Any help would be greatly appreciated. This site is a shared site hosted by Network Solutions (Unix), so my access options are limited. I can edit .htaccess files, and php.ini, but that's about all I have access to. It appears I can't even log on via shell. ETA: 11/11/2010 Thanks all. I was able to work around this problem by setting up the CMS's settings in a different way. I'd be interested in following up on Nick O'Niel's suggestions, because I think he's on the right track, but unfortunately I can't access the necessary files on this particular server. So, anyway, I'm leaving this open, since the original questions isn't exactly resolved. Unfortunately, I probably can't put a correct answer to the test, since the shared server in question has nearly all of its config files tightly locked down.

• Users removing Administrator from files/folders permissions

  - by user64204

  We're running Windows Server 2003 R2 with Active Directory and are having an issue with network shares whereby users, in an attempt to secure their documents, remove everybody (including the Administrator account) from their files/folders permissions. Since the Administrator no longer has read permission to them, we can't even backup files manually as we get permission errors. One solution that we've found is to change the owner of the files and directories to the Administrator account. We can then change the permissions as we wish. The problem is that this has to be done manually so can't really be applied to an entire share. Another solution that we've tried is to use cacls as follows: cacls d:\path\to\share /C /T /E /G Administrator:F The problem with this is that we're still getting an ACCESS DENIED error on files/folders on which Administrator was removed. Q1: Is there a way to restore at least read access to all files/folders to the Administrator account in a recursive fashion? That would be for the short term. For the long term we're looking for a solution to prevent users from removing Administrator from files/folders permissions. Since we're going to migrate to Windows Server 2008 R2 soon we could wait until we've migrated to implement such solution if need be. Q2: Is there a way to prevent users from removing Administrator from files/folders permissions on Windows Server 2003/2008?

• Moving a lot of small files between servers using rsync

  - by Adirael

  Hello guys, I'm moving a lot of files (about 2 millions) between two servers on different locations using rsync over ssh, it seems to work fine but I just realised I'm losing some files on the process. I got server 1, with the original data, and server 2, with the copy. Server 1 runs CentOS 5 and Server 2 runs on Ubuntu 10. I'm doing the transfer on the Server's 2 command line like this: rsync -e ssh -avzn usr@server1:/remote/path /local/path The first file movement I did using tar, but I didn't though of piping it through ssh and it failed cause the disk on server 1 was almost full, so I transfered it anyways (it was about 200GB) and got about 80% of the files. Then I piped another tar with the rest of the files (they're in folders, I got 100 folders with about 30 subfolders each, with files inside) and now I got everything on server 2. I wanted to be sure, so I my two options are getting the md5sum of all the files and check them or running an rsync on server 2 against server 1, that's what I did. It got some missing stuff and now it says there's nothing more to do (DRY RUN). But I got at least two files that are missing inside a subfolder. I ran that same rsync on that folder, but still dry run. Am I doing something wrong? Thanks, and sorry for the wall of text.

• Viewing local websites on my iOS device over Wi-fi

  - by John

  Trying to view some local html/css/js files in a mobile browser on my iOS device. Thought maybe file-sharing would be an option, and is, but I'm not completely satisfied with it. Any time I try to do the following an error occurs. Web sharing is on and available at http://192.168.1.101/~user but I have to manually copy the files in. If I try to symlink a folder in so that the address could be viewed at ''~user/some_dir by issuing $ ln -s /Users/user/dev/some_dir ~/Sites/ then I get a 403 forbidden error. I've tried to remedy this by modifying a user.conf file in /private/etc/apache2/ and using the following syntax: <Directory "/Users/user/Sites/"> Options Indexes MultiViews SymLinks AllowOverride None Order allow,deny Allow from all </Directory> but nope, still doesn't work. I get a 403 error. If I try to symlink each individual file in instead of using a directory as a sub-directory, same error. Any help would be greatly appreciated! I'd just like to symlink directories into the ~/Sites one and browse them on my iOS device over wifi. I'm on OS X 10.7 Lion trying to connect with iOS 5.

• Rsync root files between systems without specifying password

  - by xpt

  This seems very tricky to me. I've set up my two systems so that I can rsync files between them as me, without specifying password. Now the the problem is to rsync files that belong to root. On both of my systems, there are no root passwords. The only way to become root is via sudo. So I can neither give a password for sudo rsyn local root@remote:, no use my ssh-agent to supply pass phrase. I don't want to set up a root password on any systems; and I do need the files to be owned by root on both systems. EDIT: Using the files that belong to root is just an example, I need a way for my unprivileged account to read/write system (including root-owned) files easily. One example is to copy my configured /root environment into the freshly-installed system. The two systems are actually two VMs under a single host, so it's not a big concern for me to copy root-owned files between them. EDIT 2: If I only want to copy my configured /root environment into the freshly-installed system, I can use tar: sudo tar cvzf - /root | ssh me@remote sudo tar xvzf - -C / But I do need rsync to update from time to time. Any easy way to make it happen? EDIT 3: Formally formulate the question Alright, it all began with the question, how to rsync files that belong to root between two systems as a normal unprivileged user, without specifying password, under the condition that, The root account is locked on both of systems. I.e., there are no root passwords. The only way to become root is via sudo (recommended security practice, see http://help.ubuntu.com/community/RootSudo) I don't want a completely passwordless sudo but don’t want to be typing passwords all the time either. The normal unprivileged user has entered their ssh pass phrase into the ssh agent. Thanks

• Use Ubuntu’s Public Folder to Easily Share Files Between Computers

  - by Chris Hoffman

  You’ve probably noticed that Ubuntu comes with a Public folder in your home directory. This folder isn’t shared by default, but you can easily set up several different types of file-sharing to easily share files on your local network. This folder was originally meant for the Personal File Sharing tool, which is no longer included with Ubuntu by default. You can install the Personal File Sharing tool or use Ubuntu’s built-in file-sharing feature to share files. HTG Explains: What Is RSS and How Can I Benefit From Using It?

• Communication Between Your PC and Azure VM via Windows Azure Connect

  - by Shaun

  With the new release of the Windows Azure platform there are a lot of new features available. In my previous post I introduced a little bit about one of them, the remote desktop access to azure virtual machine. Now I would like to talk about another cool stuff – Windows Azure Connect.   What’s Windows Azure Connect I would like to quote the definition of the Windows Azure Connect in MSDN With Windows Azure Connect, you can use a simple user interface to configure IP-sec protected connections between computers or virtual machines (VMs) in your organization’s network, and roles running in Windows Azure. IP-sec protects communications over Internet Protocol (IP) networks through the use of cryptographic security services. There’s an image available at the MSDN as well that I would like to forward here As we can see, using the Windows Azure Connect the Worker Role 1 and Web Role 1 are connected with the development machines and database servers which some of them are inside the organization some are not. With the Windows Azure Connect, the roles deployed on the cloud could consume the resource which located inside our Intranet or anywhere in the world. That means the roles can connect to the local database, access the local shared resource such as share files, folders and printers, etc.   Difference between Windows Azure Connect and AppFabric It seems that the Windows Azure Connect are duplicated with the Windows Azure AppFabric. Both of them are aiming to solve the problem on how to communication between the resource in the cloud and inside the local network. The table below lists the differences in my understanding. Category Windows Azure Connect Windows Azure AppFabric Purpose An IP-sec connection between the local machines and azure roles. An application service running on the cloud. Connectivity IP-sec, Domain-joint Net Tcp, Http, Https Components Windows Azure Connect Driver Service Bus, Access Control, Caching Usage Azure roles connect to local database server Azure roles use local shared files,  folders and printers, etc. Azure roles join the local AD. Expose the local service to Internet. Move the authorization process to the cloud. Integrate with existing identities such as Live ID, Google ID, etc. with existing local services. Utilize the distributed cache.   And also some scenarios on which of them should be used. Scenario Connect AppFabric I have a service deployed in the Intranet and I want the people can use it from the Internet.   Y I have a website deployed on Azure and need to use a database which deployed inside the company. And I don’t want to expose the database to the Internet. Y   I have a service deployed in the Intranet and is using AD authorization. I have a website deployed on Azure which needs to use this service. Y   I have a service deployed in the Intranet and some people on the Internet can use it but need to be authorized and authenticated.   Y I have a service in Intranet, and a website deployed on Azure. This service can be used from Internet and that website should be able to use it as well by AD authorization for more functionalities. Y Y   How to Enable Windows Azure Connect OK we talked a lot information about the Windows Azure Connect and differences with the Windows Azure AppFabric. Now let’s see how to enable and use the Windows Azure Connect. First of all, since this feature is in CTP stage we should apply before use it. On the Windows Azure Portal we can see our CTP features status under Home, Beta Program page. You can send the apply to join the Beta Programs to Microsoft in this page. After a few days the Microsoft will send an email to you (the email of your Live ID) when it’s available. In my case we can see that the Windows Azure Connect had been activated by Microsoft and then we can click the Connect button on top, or we can click the Virtual Network item from the left navigation bar.   The first thing we need, if it’s our first time to enter the Connect page, is to enable the Windows Azure Connect. After that we can see our Windows Azure Connect information in this page.   Add a Local Machine to Azure Connect As we explained below the Windows Azure Connect can make an IP-sec connection between the local machines and azure role instances. So that we firstly add a local machine into our Azure Connect. To do this we will click the Install Local Endpoint button on top and then the portal will give us an URL. Copy this URL to the machine we want to add and it will download the software to us. This software will be installed in the local machines which we want to join the Connect. After installed there will be a tray-icon appeared to indicate this machine had been joint our Connect. The local application will be refreshed to the Windows Azure Platform every 5 minutes but we can click the Refresh button to let it retrieve the latest status at once. Currently my local machine is ready for connect and we can see my machine in the Windows Azure Portal if we switched back to the portal and selected back Activated Endpoints node.   Add a Windows Azure Role to Azure Connect Let’s create a very simple azure project with a basic ASP.NET web role inside. To make it available on Windows Azure Connect we will open the azure project property of this role from the solution explorer in the Visual Studio, and select the Virtual Network tab, check the Activate Windows Azure Connect. The next step is to get the activation token from the Windows Azure Portal. In the same page there is a button named Get Activation Token. Click this button then the portal will display the token to me. We copied this token and pasted to the box in the Visual Studio tab. Then we deployed this application to azure. After completed the deployment we can see the role instance was listed in the Windows Azure Portal - Virtual Connect section.   Establish the Connect Group The final task is to create a connect group which contains the machines and role instances need to be connected each other. This can be done in the portal very easy. The machines and instances will NOT be connected until we created the group for them. The machines and instances can be used in one or more groups. In the Virtual Connect section click the Groups and Roles node from the left side navigation bar and clicked the Create Group button on top. This will bring up a dialog to us. What we need to do is to specify a group name, description; and then we need to select the local computers and azure role instances into this group. After the Azure Fabric updated the group setting we can see the groups and the endpoints in the page. And if we switch back to the local machine we can see that the tray-icon have been changed and the status turned connected. The Windows Azure Connect will update the group information every 5 minutes. If you find the status was still in Disconnected please right-click the tray-icon and select the Refresh menu to retrieve the latest group policy to make it connected.   Test the Azure Connect between the Local Machine and the Azure Role Instance Now our local machine and azure role instance had been connected. This means each of them can communication to others in IP level. For example we can open the SQL Server port so that our azure role can connect to it by using the machine name or the IP address. The Windows Azure Connect uses IPv6 to connect between the local machines and role instances. You can get the IP address from the Windows Azure Portal Virtual Network section when select an endpoint. I don’t want to take a full example for how to use the Connect but would like to have two very simple tests. The first one would be PING.   When a local machine and role instance are connected through the Windows Azure Connect we can PING any of them if we opened the ICMP protocol in the Filewall setting. To do this we need to run a command line before test. Open the command window on the local machine and the role instance, execute the command as following netsh advfirewall firewall add rule name="ICMPv6" dir=in action=allow enable=yes protocol=icmpv6 Thanks to Jason Chen, Patriek van Dorp, Anton Staykov and Steve Marx, they helped me to enable  the ICMPv6 setting. For the full discussion we made please visit here. You can use the Remote Desktop Access feature to logon the azure role instance. Please refer my previous blog post to get to know how to use the Remote Desktop Access in Windows Azure. Then we can PING the machine or the role instance by specifying its name. Below is the screen I PING my local machine from my azure instance. We can use the IPv6 address to PING each other as well. Like the image following I PING to my role instance from my local machine thought the IPv6 address.   Another example I would like to demonstrate here is folder sharing. I shared a folder in my local machine and then if we logged on the role instance we can see the folder content from the file explorer window.   Summary In this blog post I introduced about another new feature – Windows Azure Connect. With this feature our local resources and role instances (virtual machines) can be connected to each other. In this way we can make our azure application using our local stuff such as database servers, printers, etc. without expose them to Internet.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Hack Extension Files to Make Them Version-Compatible for Firefox

  - by Asian Angel

  A well known drawback in using Firefox is the problem with extension compatibility when a new major version is released. Whether it is for a new extension that you are trying for the first time or an old favorite we have a way to get those extensions working for you again. There are multiple reasons why you might want to choose this method to fix a non-compatible extension: You are uncomfortable with tweaking the “about:config” settings You prefer to maintain the original “about:config” settings in a pristine state and like having compatibility checking active You are looking to gain some “geek cred” Keep in mind that most extensions will work perfectly well with a new version of Firefox and simply have the “version compatibility number” problem. But once in a while there may be one that needs to have some work done on it by the extension’s author. The Problem Here is a perfect example of everyone’s least favorite “extension message”. This is the last thing that you need when all that you want is for your favorite extension (or a new one) to work on a fresh clean install. Note: This works nicely to “replace” non-compatible extensions already present in your browser if you are simply upgrading. Hacking the XPI File For this procedure you will need to manually download the extension to your hard-drive (right click on the extension’s “Install Button” and select “Save As”). Once you have done that you are ready to start hacking the extension. For our example we chose the “GCal Popup Extension”. The best thing to do is place the extension in a new folder (i.e. the Desktop or other convenient location) then unzip it just the same way that you would with any regular zip file. Once it is unzipped you will see the various folders and files that were in the “xpi file” (we had four files here but depending on the extension the number may vary). There is only one file that you need to focus on…the “install.rdf” file. Note: At this point you should move the original extension file to a different location (i.e. outside of the folder) so that it is no longer present. Open the file in “Notepad” so that you can change the number for the “maxVersion”. Here the number is listed as “3.5.*” but we needed to make it higher… Replacing the “5” with a “7” is all that we needed to do. Once you have entered your new “maxVersion” number save the file. At this point you will need to re-zip all of the files back into a single file. Make certain that you “create” a file with the “.zip file extension” otherwise this will not work. Once you have the new zip file created you will need to rename the entire file including the “file extension”. For our example we copied and pasted the original extension name. Once you have changed the name click outside of the “text area”. You will see a small message window like this asking for confirmation…click “Yes” to finish the process. Now your modified/updated extension is ready to install. Drag the extension into your browser to install it and watch that wonderful “Restart to complete the installation.” message appear. As soon as your browser starts you can check the “Add-ons Manager Window” and see the version compatibility numbers for the extension. Looking very very nice! And just like that your extension should be up and running without any problems. Conclusion If you are looking to try something new, gain some geek cred, or just want to keep your Firefox install as close to the original condition as possible this method should get those extensions working nicely for you again.

• .NET Reference "Copy Local" True / False Being Set Based on Contents of GAC

  - by D-Sect

  We had a very interesting problem with a Win Forms project. It's been resolved. We know what happened, but we want to understand why it happened. This may help other people out in the future who have a similar problem. The WinForms project failed on 2 of our client's PCs. The error was an obscure kernel.dll error. The project ran fine on 3 other PCs. We found that a .DLL (log4net.dll - a very popular open-source logging library) was missing from our release folder. It was previously in our release folder. Why was it missing in this latest release? It was missing because I must have installed a program on my Dev box that used log4net.dll and it was added to the Global Assembly Cache. When I checked the solution's references for log4net.dll, they were changed to "copy local=FALSE". They must have changed automatically because log4net.dll was present in my GAC. Here's where my question starts: Why did my reference for log4net.dll get changed from COPY LOCAL = TRUE to COPY LOCAL = FALSE? I suspect it's because it was added to my GAC by another program. How can we prevent this from happening again? As it stands now, if I install a piece of software that uses a common library and it adds it to my GAC, then my SLNs that reference that DLL will change from Copy Local TRUE to FALSE.

• Dash music lens doesn't play music files

  - by scofandr

  After installing 12.10 music lens in Dash worked not for a long time. After a little while buttons "Open in directory" and "Play" (or whatever there was) just dissapeared. The only thing I can notice is that I have immediately removed Rhythmbox (as I used to do) and installed Banshee from quantal main. Besides, track length is not being displayed correctly any more. Something like 4838:32 is shown. The situation is the same for both single tracks or albums. But music files from main menu (for example, recent files) in dash have all features working: "E-mail", "Open" and "Play". Is there any way to solve all this? Hope there's no need to reinstall Rhythmbox...

• Editing Project files, Resource Editors in VS 2010

  - by rajbk

  Editing Project Files Visual Studio 2010 gives you the ability to easily edit the project file associated with your project (.csproj or .vbproj). You might do this to change settings related to how the project is compiled since proj files are MSBuild files. One would normally close Visual Studio and edit the proj file using a text editor.  The better way is to first unload the project in Visual Studio by right clicking on the project in the solution explorer and selecting “Unload Project”   The project gets unloaded and is marked “unavailable” The project file can now be edited by right clicking on the unloaded project.    After editing the file, the project can be reloaded. Resource editors in VS 2010 Visual studio also comes with a number of resource editors (see list here). For example, you could open a file using the Binary editor like so. Go to File > Open > File.. Select a File and choose the “Open With..” option in the bottom right.   We are given the option to choose an editor.   Note that clicking on the “Add..” in the dialog above allows you to include your favorite editor.   Choosing the “Binary editor” above allows us to edit the file in hex format. In addition, we can also search for hex bytes or ASCII strings using the Find command.   The “Open With..” option is also available from within the solution explorer as shown below: Enjoy!   Mr. Incredible: No matter how many times you save the world, it always manages to get back in jeopardy again. Sometimes I just want it to stay saved! You know, for a little bit? I feel like the maid; I just cleaned up this mess! Can we keep it clean for... for ten minutes!
