• Booting 11.10 from USB stick on MacBook Pro 5,1 fails

  - by Helge Stenström

  I've created a bootable memory stick on a Windows computer, and tested it on an HP PC. It's made from a 64-bit image of Ubuntu 11.10, downloaded from http://www.ubuntu.com/download/ubuntu/download. When I boot from this memory stick, there is some kind of boot menu, where I can choose to run Ubuntu from the memory stick, or install. I select Run from memory stick. (the words may be wrong here, I'm taking it from memory.) From this point, the screen is black (but backlighted), and I can't do anything but turn off the computer. It gets hot, too. Has anyone been more successful than me? Are there known issues? The computer is a 15 inch MacBook Pro 5,1 (unibody, late 2008), 4 GB memory.

• ibus symbol disappears for Japanese language selection

  - by Christian Becker-Asano

  Similar to this post No ibus icon in Kubuntu, I have trouble with the ibus icon in Ubuntu 12.04. Each time an update is installed, the language selector for Japanese disappears from the top panel. I need to uninstall and install Japanese again, then reboot, to make the symbol appear again. In this thread No iBus icon in Kubuntu 12.04 the suggestion was to install the Japanese Version of Ubuntu, but is it really true that one has to stick to a special version of Ubuntu to get this problem solved? If so, how can I transfer the settings easily from the current version to the Japanese one?

• What is stored in %Windir%\System32\LogFiles\WMI\RtBackup?

  - by Helge Klein

  I occasionally notice in Resource Monitor hard disk activity related to ETL files in the folder C:\Windows\System32\LogFiles\WMI\RtBackup. Which process/service creates these ETL files and what is their purpose? Resource Monitor shows "System" as the process which is correct since ETW traces (that is what ETL files are) are created by the kernel. But I am interested in the process that causes the traces to be created. This happens on Windows 7, by the way.

• Outlook 2010: When sending message on behalf of someone else, store that message in the other person's Sent Items folder

  - by Helge Klein

  We have an e-mail account for support purposes which is tended to by multiple members of the team. When answering a support e-mail we obviously choose the support account as sender. Still, the answer is not stored in the support account's Sent Items folder, but in the Sent Items of the person actually answering. This behavior, which seems to be by design, prevents others from gaining access to the entire conversation and potentially causes multiple answers. I am looking for an automated way of moving e-mails sent on behalf of someone else to that person's Sent Items folder. I tried to create a rule for this but could not find the right setting.

• Connections to SSH and Samba suffer from heavy delay

  - by Till Helge Helwig

  There are a lot of questions about SSH connections being delayed, which usually can be fixed by disabling the DNS lookups. Unfortunately this doesn't seem to be my problem. Our development server is accessed via SSH and Samba. When opening a connection to the server (either SSH or Samba) it takes a very long time. Accessing a Samba share via Windows is basically impossible because there is a timeout. Using smbclient works, but takes ages. When opening a SSH connection I get immediately prompted for the password and after hitting Enter the terminal instantly shows the MOTD. Afterwards it takes about a minute for the prompt to appear. I watched the load of the server while connecting via SSH and Samba and could not find anything out of order. There is nothing out of the ordinary running and hogging up memory and CPU or something. I have no clue where this delay might come from. I already tried UseDNS no in sshd_config and proxy_dns = no in smb.conf, but to no avail. Any idea about what might cause this would be greatly appreciated!

• KDE4: Share Nepomuk data

  - by Frank Becker

  Hi all, is it possible to share the nepomuk data? I have several users here and the users should be able to read and modify the tags and comments for each file with public access. Also it should be possible to tag and comment the files in each private home-directory. Is this possible with the current KDE 4.3.2? Thanks for your help Frank

• Windows XP/7: custom routing for VPN connection

  - by Peter Becker

  We are dealing with a badly configured VPN connection from a vendor, which set up the default gateway but doesn't route traffic anywhere beyond their VPN zone. I managed to do some ad-hoc routing to configure a computer in a way that it can reach the vendor's VPN, our local network as well as the internet. I then tried to turn this into a script, but that failed since the interface number of the VPN changes on every connection. Is there a way in Windows XP and/or Windows 7 to configure custom routing on the client side of a VPN connection? What I would like to do is to have a script running just after the connection comes up that changes the routing table (similar to an ifup script on UNIX).

• WPF TreeView: How to style selected items with rounded corners like in Explorer

  - by Helge Klein

  The selected item in a WPF TreeView has a dark blue background with "sharp" corners. That looks a bit dated today: I would like to change the background to look like in Explorer of Windows 7 (with/without focus): What I tried so far does not remove the original dark blue background but paints a rounded border on top of it so that you see the dark blue color at the edges and at the left side - ugly. Interestingly, when my version does not have the focus, it looks pretty OK: I would like to refrain from redefining the control template as shown here or here. I want to set the minimum required properties to make the selected item look like in Explorer. Alternative: I would also be happy to have the focused selected item look like mine does now when it does not have the focus. When losing the focus, the color should change from blue to grey. Here is my code: <TreeView x:Name="TreeView" ItemsSource="{Binding TopLevelNodes}" VirtualizingStackPanel.IsVirtualizing="True" VirtualizingStackPanel.VirtualizationMode="Recycling"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" /> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" /> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="BorderBrush" Value="#FF7DA2CE" /> <Setter Property="Background" Value="#FFCCE2FC" /> </Trigger> </Style.Triggers> </Style> </TreeView.ItemContainerStyle> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type viewmodels:ObjectBaseViewModel}" ItemsSource="{Binding Children}"> <Border Name="ItemBorder" CornerRadius="2" Background="{Binding Background, RelativeSource={RelativeSource AncestorType=TreeViewItem}}" BorderBrush="{Binding BorderBrush, RelativeSource={RelativeSource AncestorType=TreeViewItem}}" BorderThickness="1"> <StackPanel Orientation="Horizontal" Margin="2"> <Image Name="icon" Source="/ExplorerTreeView/Images/folder.png"/> <TextBlock Text="{Binding Name}"/> </StackPanel> </Border> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView>

• Singelton on iPhone Simulator vs Singelton on real Device

  - by Helge Becker

  I am using a Singelton for some shared stuff. In the simulator, the app crashes ocasionally. Tracking the crash down shows that the the properties of my Singelton became dealocated. Those crashes never happend on a real device. Does the iPHone simulator handle memory managemend different? GC maybe? Changed the singelton to match this pattern. The iPhone Simulator dont crash now, but I am not sure about the memory handling on the real device. I assume that this solution will cause problems. What do you think?

• A wee bit exhausted… time to reenergize

  - by drsql

  I admit it. I am tired and I have not blogged nearly enough. This has been a crazy year, with the book I finished writing , the pre-cons I have done (teaching is NOT my primary profession so I do a lot more prep than some others probably do), lots of training on Data Warehousing topics (from Ralph Kimball, Bob Becker, and Stacia Misner, to name three of the great teachers I have had), SQL Rally, SQL PASS, SQL Saturdays and I have gotten a lot more regular with my simple-talk blog as well… Add to...(read more)

• Will .Net 4.0 include a new CLR or keep with version 2.0

  - by Rory Becker

  Will .Net 4.0 use a new version of the CLR (v2.1, 3.0) or will it stick with the existing v2.0? Supplementary: Is it possibly going to keep with CLR v2.0 and add DLR v1.0? Update: Whilst this might look like a speculative question which cannot be answered, the VS team appear to be releasing more and more info on VS10 and .Net 4.0 so this may very soon not be the case.

• How to manage test fixtures for end-to-end testing?

  - by Peter Becker

  Having just set up a test framework for a new web application, I realized I missed one of the big questions: "How do I make tests independent from each other?" Years ago I have set up some complicated Ant scripting to do full cycles of deleting all database tables, creating the schema again, adding test data, starting the application, running one test and then stopping the application. That was a pain to maintain and restricted us to nightly tests due to the time it took to run the full suite. It was still worth it, but I wonder if there is an easier way. Are there alternatives to this approach? The main criterion is that each test should not be affected by any other test in the suite, no matter if it failed or succeeded.

• How do I shrink my SQL Server Database?

  - by Rory Becker

  I have a Database nearly 1.9Gb Database in size MSDE2000 does not allow DBs that exceed 2.0Gb I need to shrink this DB (and many like it at various client locations) I have found and deleted many 100's of 1000's of records which are considered unneeded. these records account for a large percentage of some of the main (largest) tables in the Database. Therefore it's reasonable to assume much space should now be retrievable. So now I need to shrink the DB to account for the missing records I execute "DBCC ShrinkDatabase('MyDB')"......No effect. I have tried the various shrink facilities provided in MSSMS.... Still no effect. I have backed up the database and restored it... Still no effect. Still 1.9Gb Why? Whatever procedure I eventually find needs to be replayable on a client machine with access to nothing other than OSql or similar.

• How do I get Nant to use the 4.0 compiler to target .Net 3.5

  - by Rory Becker

  Yes I know that sounds a little bit crazy, but I've got .Net 3.5 deployed in the field and I'd like to use the new 4.0 compiler to target it. There are several new syntactic sugar features in the latest versions of Vb.Net and C# which I would like to use,but I am unable (just yet) to enforce a new version of the .Net framework and CLR on my client base. Before the nay sayers jump in with both feet... I have just successfully used Studio 2010 to compile a 3.5 targeted app which used VB.Net auto properties (A new feature in VB.Net 10) so I know the compilers are capable somehow. So back to my question.... How do I convince Nant to use the 4.0 compiler, but to target .Net 3.5 (CLR 2.0) Update: I am using the csc and vbc tasks and not the Solution task. although I'd settle for an answer on how to do this direct with the compilers at this point.

• How to launch correct version of Msbuild

  - by Rory Becker

  When I type... Msbuild<Enter> ... At the command prompt, I get... Microsoft (R) Build Engine Version 2.0.50727.4927 [Microsoft .NET Framework, Version 2.0.50727.4927] Copyright (C) Microsoft Corporation 2005. All rights reserved. This is all very well and good except that when I run this against a vs2010 .sln file, the error message indicates: MyProject.sln(2): Solution file error MSB5014: File format version is not recognized. MSBuild can only read solution files between versions 7.0 and 9.0, inclusive. 0 Warning(s) 1 Error(s) It would appear that the version of msbuild that is being called, is not capable of understanding my solution file. I figured that I would check out my path and see where msbuild is being picked up from. However, it seems that no part of my path points at a location where msbuild is to be found. How is the command line finding the copy of msbuild that it is using and how can I change this version so that the latest version is used?

• How well are SVG filter elements defined?

  - by Peter Becker

  We are considering using SVG filters as part of our toolchain, serving the SVG to browsers capable of supporting it, while serving pre-rendered PNGs to other. One problem we noticed is that the rendering of the filter chains seems to be very inconsistent across renderers. When looking at the "filters01" example from the SVG specification, the rendering looks very different across the tools we tried. Chrome (5.0.307.11) failed to render the image, while other tools (Firefox 3.6, Opera 10.10, Inkscape 0.47, GIMP 2.6.7) render something vaguely similar in style to the picture in the specification, but no two are truly the same. Is that an issue of under-specification or are the tools just not there? If we would use SVG with filter effects: is there a reference tool that can give us a rendering the way it is intended by the spec?

• Does VS2010 use csc.exe / vbc.exe (directly or indirectly) to compile relevant projects?

  Pretty much as the title suggests. I can't find any proof that DevEnv.exe actually calls these at any point.

• Is there a way to disable calls to Runtime.checkRestricted on the GAE Java development server under Eclipse?

  - by Thomas Becker

  I'm one of those guys who step through their code a lot during development. Beginning with version 1.6.4 of the GAE Java development server, the server has been instrumented with calls to a function named Runtime.checkRestricted. This causes two inconveniences when I step through my code: 1) Whenever I step into a function, the debugger goes into the function Runtime.checkRestricted (for which there is no source code) at least once, often multiple times. 2) Whenever I step over a function call which has a large call tree underneath it, then it takes a very long time for the debugger to come back. (That's always a problem in the Eclipse Java debugger, but now it's really bad.) For me, all this causes a serious drain on productivity. Is there any way to disable this instrumentation, or to prevent the debugger from stepping into it? I am using Eclipse with the GAE plugin.

• How to get ANTLR 3.2 to exit upon first error?

  - by Dan Becker

  In section 10.4, The Definitive ANTLR reference tells you to override mismatch() & recoverFromMismatchedSet() if you want to exit upon the first parsing error. But, at least in ANTLR 3.2, it appears that there is no mismatch() method, and the recoverFromMismatchedSet() documentation says that it is "Not Currently Used". So it appears things have changed since the book was published. What am I supposed to do instead to exit upon the first parsing error in ANTLR 3.2?

• How do I simulate the usage of a sequence of web pages?

  - by Rory Becker

  I have a simple sequence of web pages written in ASP.Net 3.5 SP1. Page1 - A Logon Form.... txtUsername, txtPassword and cmdLogon Page2 - A Menu (created using DevExpress ASP.Net controls) Page3 - The page redirected to by the server in the event that the user picks the right menu option in Page2 I would like to create a threaded program to simulate many users trying to use this sequence of pages. I have managed to create a host Winforms app which Launches a new thread for each "User" I have further managed to work out the basics of WebRequest enough to perform a request which retrieves the Logon page itself. Dim Request As HttpWebRequest = TryCast(WebRequest.Create("http://MyURL/Logon.aspx"), HttpWebRequest) Dim Response As HttpWebResponse = TryCast(Request.GetResponse(), HttpWebResponse) Dim ResponseStream As StreamReader = New StreamReader(Response.GetResponseStream(), Encoding.GetEncoding(1252)) Dim HTMLResponse As String = ResponseStream.ReadToEnd() Response.Close() ResponseStream.Close() Next I need to simulate the user having entered information into the 2 TextBoxes and pressing logon.... I have a hunch this requires me to add the right sort of "PostData" to the request. before submitting. However I'm also concerned that "ViewState" may be an issue. Am I correct regarding the PostData? How do I add the postData to the request? Do I need to be concerned about Viewstate? Update: While I appreciate that Selenium or similar products are useful for acceptance testing , I find that they are rather clumsy for what amounts to load testing. I would prefer not to load 100 instances of Firefox or IE in order to simulate 100 users hitting my site. This was the reason I was hoping to take the ASPNet HttpWebRequest route.

• How do I debug into an ILMerged assembly?

  - by Rory Becker

  Summary I want to alter the build process of a 2-assembly solution, such that a call to ILMerge is invoked, and the build results in a single assembly. Further I would like to be able to debug into the resultant assembly. Preparation - A simple example New Solution - ClassLibrary1 Create a static function 'GetMessage' in Class1 which returns the string "Hello world" Create new console app which references the ClassLibrary. Output GetMessage from main() via the console. You now have a 2 assembly app which outputs "Hello World" to the console. So what next..? I would like to alter the Console app build process, to include a post build step which uses ILMerge, to merge the ClassLibrary assembly into the Console assembly After this step I should be able to: Run the Console app directly with no ClassLibrary1.dll present Run the Console app via F5 (or F11) in VS and be able to debug into each of the 2 projects. Limited Success I read this blogpost and managed to achieve the merge I was after with a post-build command of... "$(ProjectDir)ILMerge.bat" "$(TargetDir)" $(ProjectName) ...and an ILMerge.bat file which read... CD %1 Copy %2.exe temp.exe ILMerge.exe /out:%2.exe temp.exe ClassLibrary1.dll Del temp.exe Del ClassLibrary1.* This works fairly well, and does in fact produce an exe which runs outside the VS environment as required. However it does not appear to produce symbols (.pdb file) which VS is able to use in order to debug into the code. I think this is the last piece of the puzzle. Does anyone know how I can make this work? FWIW I am running VS2010 on an x64 Win7 x64 machine.

• Using member variables inherited from a templated base class (C++)

  - by Aaron Becker

  I'm trying to use member variables of a templated base class in a derived class, as in this example: template <class dtype> struct A { int x; }; template <class dtype> struct B : public A<dtype> { void test() { int id1 = this->x; // always works int id2 = A<dtype>::x; // always works int id3 = B::x; // always works int id4 = x; // fails in gcc & clang, works in icc and xlc } }; gcc and clang are both very picky about using this variable, and require either an explicit scope or the explicit use of "this". With some other compilers (xlc and icc), things work as I would expect. Is this a case of xlc and icc allowing code that's not standard, or a bug in gcc and clang?

• Why does a change of Session State provider lead to an ASPx page yielding garbage?

  - by Rory Becker

  I have an aspnet webapp which has worked very well up until now. I was recently asked to explore ways of making it scale better. I found that seperation of database and Webapp would help. Further I was told that if I changed my session providing mechanism to SQLServer, I would be able to duplicate the Web Stack to several machines which could each call back to the state server allowing the load to be distirbuted better. This sounds logical. So I created an ASPState database using ASPNet_RegSQL.exe as detailed in many locations across the web and changed the web.config on my app from: <sessionState mode="InProc" cookieless="false" timeout="20" /> To: <sessionState mode="SQLServer" sqlConnectionString="Server=SomeSQLServer;user=SomeUser;password=SomePassword" cookieless="false" timeout="20" /> Then I addressed my app, which presented me with its logon screen and I duly logged in. Once in I was presented, not with the page I was expecting, but with: I can change the sessionstate back and forth. This problem goes away and then comes back based on which set of configuration I use. Why is this happening?

• How much effort does it take to spoof an Ip Address in a call to a webservice?

  - by Rory Becker

  I don't want to know how... Just how complicated.... I'm thinking of securing a webservice or 2 based on the incoming client ipaddress of the caller. Is this in any way secure? Surely if the IPaddress was being spoofed then the result would have to be sent back to the address that was being spoofed and therefore not reach the spoofer? Update: Ok so from what I can tell.... I should create a Gettoken() method which checks the IPaddress and passes out a cryptographically significant token with a timeout to any valid IP address. This is then required by any other method before any kind of side effect is allowed. Since an Attacker can't (likely) get the token without having a valid IP, he will be unable to validly call any of my "dangerous" webmethods ?
