  • How to simply remove everything from a directory on Linux

    - by Tometzky
    How to simply remove everything from a current or specified directory on Linux? Several approaches: rm -fr * rm -fr dirname/* Does not work — it will leave hidden files — the one's that start with a dot, and files starting with a dash in current dir, and will not work with too many files rm -fr -- * rm -fr -- dirname/* Does not work — it will leave hidden files and will not work with too many files rm -fr -- * .* rm -fr -- dirname/* dirname/.* Don't try this — it will also remove a parent directory, because ".." also starts with a "." rm -fr * .??* rm -fr dirname/* dirname/.??* Does not work — it will leave files like ".a", ".b" etc., and will not work with too many files find -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr find dirname -mindepth 1 -maxdepth 1 -print0 | xargs -0 rm -fr As far as I know correct but not simple. find -delete find dirname -delete AFAIK correct for current directory, but used with specified directory will delete that directory also. find -mindepth 1 -delete find dirname -mindeph 1 -delete AFAIK correct, but is it the simplest way?

  • Just LB or also Web Servers in Demilitarized Zone?

    - by Bradford
    In a load balanced environment, is it necessary to have all of the web servers in the DMZ? Or will just having the Load Balancer in the DMZ achieve the desired security? If it matters, the web server and application server are the same -- GF, Tomcat fronted by httpd on the same server, OAS, etc... LB - WEB/APPLICATION - DB Also, would the setup be different if it was LB - Web Server - Application Server - DB Thanks, Bradford

  • Why won't this SQL CAST work?

    - by Kev
    I have a nvarchar(50) column in a SQL Server 2000 table defined as follows: TaskID nvarchar(50) NULL I need to fill this column with some random SQL Unique Identifiers (I am unable to change the column type to uniqueidentifier). I tried this: UPDATE TaskData SET TaskID = CAST(NEWID() AS nvarchar) but I got the following error: Msg 8115, Level 16, State 2, Line 1 Arithmetic overflow error converting expression to data type nvarchar. I also tried: UPDATE TaskData SET TaskID = CAST(NEWID() AS nvarchar(50)) but then got this error: Msg 8152, Level 16, State 6, Line 1 String or binary data would be truncated. I don't understand why this doesn't work but this does: DECLARE @TaskID nvarchar(50) SET @TaskID = CAST(NEW() AS nvarchar(50)) I also tried CONVERT(nvarchar, NEWID()) and CONVERT(nvarchar(50), NEWID()) but got the same errors.

  • Javascript Phone Swap

    - by Batfan
    I've been trying to find a way to do this but, have not found many resources that specifically relate to this situation. I need a javascript (can make use of Jquery if need be) to swap phone numbers on a site. 2 numbers would be specified. One would show on the site by default. The script needs to be able to create a cookie and do this by recognizing a value in the URL string. For Example: http://www.site.com/index.html?value= '?value=' would be the value. This URL (with the additional variable) would bring the user to the same site but, the variable in the string would set the cookie and display a different number. The default number would not be displayed again until the cookies were removed. Due to the situation with my server, I cannot make use of PHP ( I know, that would make things alot easier :P ) Any help would be greatly appreciated.

  • Getting Active Session counts with JMX (Java Management Extensions) API

    - by bLee
    I'm trying to use JMX API to get active session counts for a web application. Is it possible to use JMX API to get this kind of information? If yes, how reliable would it be? Any example code on how to get this done? I've been reading JMX tutorial and documentation, but they are giving me the overview of what the technology is. I just can't pinpoint to what I need, yet.

  • WPF: Horizontal Alignment

    - by emptyset
    Probably I'm just missing something obvious, but I can't get the image in my DataTemplate to align to the right in the Grid, so that when the window is stretched, the image is "pulled" to the right as well: <Window.Resources> <DataTemplate x:Key="PersonTemplate" DataType="Minimal.Client.Person"> <Border BorderBrush="Purple" BorderThickness="2" CornerRadius="2" Padding="5" Margin="5"> <Grid Margin="10"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" MinWidth="200"/> <ColumnDefinition Width="Auto" MaxWidth="200"/> </Grid.ColumnDefinitions> <StackPanel Grid.Column ="0" Orientation="Horizontal" > <TextBlock FontFamily="Verdana" FontSize="16" FontWeight="Bold" Text="{Binding LastName}" /> <TextBlock FontFamily="Verdana" FontSize="16" Text=", " /> <TextBlock FontFamily="Verdana" FontSize="16" Text="{Binding FirstName}" /> </StackPanel> <StackPanel Grid.Column="1" Orientation="Vertical" HorizontalAlignment="Right"> <Border BorderBrush="Black" BorderThickness="1"> <Image Source="{Binding Picture}" Width="180" Height="150" /> </Border> </StackPanel> </Grid> </Border> </DataTemplate> </Window.Resources> Any suggestions?

  • Ok to use VirtualProtect to change resource in Delphi?

    - by user257188
    I'm working on a simple localization effort in D2010. I'm handling all strings on forms because ETM seems like overkill for my needs, as did other 3rd party tools... (although I'm not so sure at this point!) Is the code below for changing the Const.pas strings considered safe to change the button labels on standard message boxes? procedure HookResourceString(rs: PResStringRec; newStr: PChar); var oldprotect: DWORD; begin VirtualProtect(rs, SizeOf(rs^), PAGE_EXECUTE_READWRITE, @oldProtect); rs^.Identifier := Integer(newStr); VirtualProtect(rs, SizeOf(rs^), oldProtect, @oldProtect); end; const NewOK: PChar = 'New Ok'; NewCancel: PChar = 'New Cancel'; Procedure TForm.FormCreate; begin HookResourceString(@SMsgDlgOK, NewOK); HookResourceString(@SMsgDlgCancel, NewCancel); end;

  • What is the difference in WCF when using KnownType and ServiceKnownType?

    - by Paul Speranza
    I have a service that returns an array of animal but the list can contain cats, dogs, etc, which all extend animal. I know I need to use either the KnownType or ServiceKnownType attribute, and on the entity class or the service class, respectively. What is the difference between the 2 attributes? I prefer the ServiceKnownType because it is applied on the service, exactly where it is needed and called for, as opposed to KnownType which is applied on my entity. To me applying it on the entity class means knowing too far ahead how my entity class is being used. For now I have it on my entity and it works like a charm, but I am looking for guidance here as to best practices and usefullness. Thanks, Paul Speranza

  • Reporting Trend Line

    - by Dave Jarvis
    Hi, How would you create a line in JasperReports that follows the trend for the data, in addition to showing the data points? Here are before and after shots: Before After The Time Series report does not appear to have any such option to draw the orange line. (The orange line should be smooth, and thinner, but that's the general idea.) Any ideas how to craft such a report?
