• How do I keep a server connected as a volume after sleep?

  - by Jason

  This would be in OS X 10.6... I know I can connect a server share as a volume and do so via a script so every time I boot up it gets mapped. How can I make sure that same share is mapped after my computer comes out of sleep mode? It seems like the connection gets dropped. Can the same process map the drive for me when I boot up?

• Slow network file copy on Windows 7

  - by Jason V.

  I wrote a program that uses xcopy to transfer files (usually between 1KB and 2MB) over our intranet. Usually, I am copying files from my host machine (Windows 7 x64) to a VMWare virtual machine running Windows Server 2008 (the VM is running on my host machine, if that matters). On Windows XP, the file transfers usually only require a few seconds to complete. But on my Windows 7 machine, the transfer of the first file (1.5 MB) takes around 1.5 minutes to complete. This is true whether I use xcopy, robocopy, or programmatically using File.Copy(). I noticed that if I use File.Copy, the first transfer is very slow and subsequent transfers are much faster. Any clue how I can speed up the process? Is there a setting in Windows 7 (or server 2008) that I could try?

• Rewrite 2 different directories with htaccess?

  - by jason

  I have a tricky problem (for me at least). I'm trying to rewrite / to a folder /webroot/www. I have some simple code and it works: RewriteRule ^$ /webroot/www/ [L] However at the same time if the URL starts with components, followed by anything else (ex. foo, as in /components/foo), and foo is an actual directory that exists inside components, I should rewrite to /components/foo/www instead. How can I achieve that? I can't seem to figure it out. I'm using Apache with .htaccess.

• Prevent Windows 7 PC from sleeping while a download is in progress

  - by Jason Sundram

  While I'm downloading a large file on Windows 7 using Google Chrome, my computer goes to sleep. I could obviously set the computer to not sleep at all (or change the interval before the computer sleeps). What I want to know is: Is there a way to make Windows 7 not sleep as long as a download is in progress? (perhaps when any network activity is going on?). I've looked in the Advanced Power settings, and haven't seen any obvious setting.

• Powering off sends me to "Launch Windows Repair" automatically instead! What do I do?

  - by Jason

  With Windows 2008 R2 Server, I noticed that if I remotely reboot the machine (because it is hung or I think it is hung), the server, when it restarts, defaults to "Launch Windows Repair" (or something similar) rather than "Start Windows Normally". To change it, I have to trek down to the server room and change the boot up otherwise it will go into an endless loop (because I don't have the setup media and DVD-ROM installed). This seems to be new with 2008 R2 because I have not seen it elsewhere. What do I do? How can I remove this or change the default?

• How can I forward certain emails based on header information with Postfix?

  - by Jason Novinger

  We receive service requests via a particular email. The request is then forwarded to other addresses, using an entry in virtual_alias_maps. Upon seeing the word "EMERGENCY" in the subject line of a request to this email, I would also like to forward this to another address (an alias of our administrator's SMS email addresses). I think I can accomplish this with header checks and the REDIRECT command. However, REDIRECT only sends it to the redirected address, not the forwarded addresses. In the case of "EMERGENCY" I would like it to go to the redirect address and the original forwarded addresses. I am fairly new to Postfix and I feel like I am missing something here. Any suggestions?

• Static IP address on Wi-Fi at work and dynamic at home?

  - by Jason Shultz

  I need the laptops at my office to have a static IP address for security purposes and identification. However, some employees take their laptops home in the evening. If I have the Wi-Fi configuration set to use a static IP address, how can they have a dynamic IP address at home? The laptops are using Windows Vista and Windows 7.

• Discover intended Foreign Keys from JOINS in scripts

  - by Jason

  I'm inheriting a database that has 400 tables and only 150 foreign key constraints registered. Knowing what I do about the application and looking at the table columns, it's easy to say that there ought to be a lot more. I'm afraid that the current application software will break if I started adding the missing FKs because the developers have probably come to rely on this "freedom", but step one in fixing the problem is to come up with the list of missing FKs so we can evaluate them as a team. To make matters worse, the referencing columns don't share a naming convention. The relationships ARE coded informally into the hundreds of ad-hoc queries and stored procedures, so my hope is to parse these files programmatically looking for JOINS between actual tables (but not table variables, etc). Challenges I foresee in this approach are: newlines, optional aliases and table hints, alias resolution. Any better ideas? (Besides quitting) Are there any pre-built tools that can solve this? I don't think regex can handle this. Do you disagree? SQL Parsers? I tried using Microsoft.SqlServer.Management.SqlParser.Parser but all that is exposed is the lexer - can't get an AST out of it - all that stuff is internal.

• developing code in multiple locations

  - by jason m

  I have two machines (one is a mac one is a pc), and I develop on both machines but only run "production" on the pc. Now, I sometimes face an issue where both machine PC and machine MAC have different versions of the same code, and I would like them to share a common source. I know this solution must exist but I have no ideat what it is called/how to start. Could someone please point me in the right direction?

• Tungsten for MySQL: Online Schema Upgrade

  - by Jason

  In a recent presentation the Continuent folks claim that they support "daylight maintenance" or online schema upgrades. See Clustering for the Masses: A Gentle Introduction to Tungsten for MySQL, especially pages 22-28. Is anyone using Tungsten for MySQL in this way? It sounds too good to be true. I also wonder if the Community Edition supports all of the features discussed in the presentation. They say elsewhere that it is not crippleware but in their own productization table "Zero downtime upgrade" appears to only be available in the more advanced versions. So I'm skeptical. Community support seems rather non-existent so a commercial license with support is probably warranted (they do not disclose pricing). I have not contacted them directly yet as I prefer community vetting but this solution, despite its value proposition and power to make an admin's life easier just doesn't seem to get the kind of attention it might warrant. If not Tungsten for MySQL, how do you handle online schema upgrades? MySQL Cluster (NDBENGINE) is not well-suited to web applications. Cheers

• how to remove location block from $uri in nginx configuration?

  - by Jason

  I have a rewrite in my ngix conf file that works properly except it seems to include the location block as part of the $uri variable. I only want the path after the location block. My current config code is: location /cargo { try_files $uri $uri/ /cargo/index.php?_REWRITE_COMMAND=$uri&args; } Using an example url of http://localhost/cargo/testpage the redirect works, however the value of the "_REWRITE_COMMAND" parameter received by my php file is "/cargo/testpage". I need to strip off the location block and just have "testpage" as the $uri I am pretty sure there is a regex syntax to split the $uri and assign it to a new variable using $1 $2 etc, but I can't find any example to do just a variable assignment using a regex that is not part of a rewrite statement. I've been looking and trying for hours and I just can't seem to get past this last step. I also know I could just strip this out on the application code, but the reason I want to try to fix it in the nginx conf is for compatibility reasons as it also runs on Apache. I also should say that I have figured out a really hacky way to do it, but it involves an "if" statement to check for file existance and the documentation specifically says not to do it that way. -- UPDATE: ANSWERED BY theuni: The regex goes in the location block definition. one note of caution is that php handler location needs to be ABOVE this location, otherwise you will get a server error because it goes into an infinite redirect loop location ~ ^/cargo/(.*) { try_files $1 /cargo/$1/ /cargo/index.php?_REWRITE_COMMAND=$1&args; }

• How to ignore hard drives size with Windows Server Backup (Win-2008) restore?

  - by Jason

  I used Windows Server Backup to backup my 640GB boot drive. Only about 30GB is used, and the backup was very fast. Now I am trying to restore the image to a 500GB hard drive but it is saying that the drive is too small... even though I only had 30GB on the original backup. How do I overide this and have the restore ignore that I only have a 500GB drive? If I can't, then I can't restore the hard drive with anything except one that is equal to or bigger than the original hard drive - which would be a real bummer.

• Changing Chrome Working Directories on Mac clients

  - by Jason

  We're using Mac OSX 10.6.8 with NFS for home directories. Chrome seems to not like this, for a user who is logged in more than one machine. AFP was ok, but for other reasons we need NFS. It only allows you to start one instance. Ie, userA logged in to Mac1, Mac2. Can only have chrome open on Mac1 OR mac2, not both. I have read at this thread, changing working directory, and sym link can fix... but I can't find the details. Can someone help?

• How do you jump to a particular row in a DataGridView by typing (a la Windows Explorer details view)

  - by russcollier

  I have a .NET Winforms app in C# with a DataGridView that's read-only and populated with some number of rows. I'd like to have functionality similar to Windows Explorer's (and many other applications) details view for example. I'd like the DataGridView to behave such that when it has focus if you start typing, the current row selection will jump to the row where the (string) value of cell 0 (i.e. the first column in the row) starts with the characters you typed in. For example, if I have a DataGridView with 1 column and the following rows: Bob Jane Jason John Leroy Sam If the DataGridView has focus and I hit the 'b' key on my keyboard, the selected row is now "Bob". If I quickly type in the keys 'ja', the selected row is Jane. If I quickly type in the letters 'jas', the selected row is Jane. If I hit the 'z' key, nothing is selected (since nothing starts with Z). Likewise if Jane is currently selected and I keep typing the letter 'j', the selection will cycle through to Jason, then John, then back to Jane, each time I hit the 'j' key. I've been doing some Googling (and "stackoverflowing" :-)) for awhile and cannot find any examples of this type of functionality. I have a rough idea in my head to do this via some sort of short lived timer thread, collecting the keystrokes on KeyPress events for the DataGridView, and selecting rows based on those collected keystrokes matching a Cells[0].Value.StartsWith() type of condition. But it seems like there has to be an easier way that I'm just not seeing. Any ideas would be much appreciated. Thanks!

• Assembly installed into the GAC not showing up in Visual Studio

  - by yodaj007

  This sounds related to this question, but they aren't the same thing. That question had no assemblies showing up. Mine has everything except the specific one I installed. I'm hoping someone has a solution to this... am I doing something wrong? Or did I find some bug in VS? I am using Visual Studio 2010 Professional Beta 2 on Windows 7 Ultimate. I just downloaded Rhino Mocks and decided to install it into the GAC using the command-line utility GACUTIL. I then rebooted. Here you can see the assembly in my GAC (click to enlarge): And here is the list of assemblies available to me in Visual Studio: Here is the command prompt where I installed it, and then confirmed it: C:\Users\jason\Downloads>gacutil -i Rhino.Mocks.dll Microsoft (R) .NET Global Assembly Cache Utility.

• WPF Dynamic Layout with ItemsControl and Grid

  - by Jason Williams

  I am creating a WPF form. One of the requirements is that it have a sector-based layout so that a control can be explicitly placed in one of the sectors/cells. I have created a tic-tac-toe example below to convey my problem: There are two types and one base type: public class XMoveViewModel : MoveViewModel { } public class OMoveViewModel : MoveViewModel { } public class MoveViewModel { public int Row { get; set; } public int Column { get; set; } } The DataContext of the form is set to an instance of: public class MainViewModel : ViewModelBase { public MainViewModel() { Moves = new ObservableCollection<MoveViewModel>() { new XMoveViewModel() { Row = 0, Column = 0 }, new OMoveViewModel() { Row = 1, Column = 0 }, new XMoveViewModel() { Row = 1, Column = 1 }, new OMoveViewModel() { Row = 0, Column = 2 }, new XMoveViewModel() { Row = 2, Column = 2} }; } public ObservableCollection<MoveViewModel> Moves { get; set; } } And finally, the XAML looks like this: <Window.Resources> <DataTemplate DataType="{x:Type vm:XMoveViewModel}"> <Image Source="XMove.png" Grid.Row="{Binding Path=Row}" Grid.Column="{Binding Path=Column}" Stretch="None" /> </DataTemplate> <DataTemplate DataType="{x:Type vm:OMoveViewModel}"> <Image Source="OMove.png" Grid.Row="{Binding Path=Row}" Grid.Column="{Binding Path=Column}" Stretch="None" /> </DataTemplate> </Window.Resources> <Grid> <ItemsControl ItemsSource="{Binding Path=Moves}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Grid ShowGridLines="True"> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> </Grid> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </Grid> What was not so obvious to me when I started was that the ItemsControl element actually wraps each item in a container, so my Grid.Row and Grid.Column bindings are ignored since the images are not directly contained within the grid. Thus, all of the images are placed in the default Row and Column (0, 0). What is happening: The desired result: So, my question is this: how can I achieve the dynamic placement of my controls in a grid? I would prefer a XAML/Data Binding/MVVM-friendly solution. Thanks.
