• Pinned program on the taskbar is not grouping in Windows 7 Ultimate

  - by Magic

  Previously, I had pinned Google Chrome Dev to the taskbar. Being that it was unstable and crashed frequently, I decided to uninstall it. Before uninstalling, however, I did not un-pin its icon from the taskbar. Afterward, I installed Google Chrome Stable and launched it from the old pinned icon. This resulted in a new icon appearing in the taskbar. I figured this happened because the icon was originally for the Dev build, so I unpinned the icon and re-pinned Google Chrome. I launch Google Chrome again, but I still get a new icon! Re-pinning the icon should have fixed it, no? Why aren't my Google Chrome windows grouping together?

• Keeping the wireless connected.

  - by casr

  I’m running OpenBSD on a computer which is connected via wireless to the network. It is a well supported NIC and I’ve had no problems with it from a hardware perspective. Unfortunately my wireless access point occasionally loves to forget it’s settings. I then have to help it remember. However, in this intervening time my OpenBSD box drops the connection and then does not automatically reconnect. I have alleviated my problems by running this simple script in the background: #!/bin/sh while [ 1 ] do ping -c1 192.168.1.254 > /dev/null if [ $? = 1 ] then sh /etc/netstart ral0 > /dev/null fi sleep 30 done [Ping the access point. If there is no response attempt to reconnect.] It seems to me to be a very suboptimal solution. Has anyone else come across a better way?

• SSL Certificate only works when session active in Server 2008

  - by CodeMonkey1

  I have a web app that uses an installed certificate to send a web request to a 3rd party web service. This has worked for a long time on Windows Server 2003, but just recently we found a problem with it on 2008 installations. When logged into the server as the same user the App Pool uses, either locally or via remote desktop, the web app and it's secure 3rd party request works fine. However, when there are no user sessions open, the 3rd party request fails, as if the certificate were not attached to the web request. Any ideas?

• How to configure Apache to act as an SSL proxy to an application server?

  - by ripper234

  I have one physical server that runs: an Apache (httpd) server another web server (let's say Tomcat for sake of argument) on port 1234 Can I configure the Apache server to act as a proxy for SSL traffic, while keeping the application server blissfully unaware of SSL? What I imagine is: Traffic to http://myserevr.com/app is redirected to https://myserver.com/app Traffic to https://myserver.com/app is proxied to the application server. My SSL certificate is only installed on the Apache server, not on the Application server Other traffic to the Apache server (http://myserver.com/anotherapp) is served directly from the Apache server What's the best setup to achieve this? (On Ubuntu, if that matters)

• Code-First Database Creation During TFS 2010 CI Build

  - by jedimindtrickster

  I would like to automate code-first database generation during the automated CI build of a web project in Team Foundation Server 2010. When run locally the tests create a code-first database specified by the connection string in the app.config of the tests project. How do I configure the TFS Build Configuration to mimic this behaviour on the TFS build server? Edit The problem, it turns out, was that the TFS build server was successfully running the test which was using the default connection string in the app.config which pointed to the local SQL Server, not where I expected it. The solution was to use SlowCheetah on the TFS server as a means to transform the App.config file using the QA transform as per this blog article.

• Uptime concerns in case of AWS outage

  - by Aditya Patawari

  I am running an Elastic Load Balancer backup by 2 instances in different Availability Zones in US East. I am using Multi-AZ RDS as well. Ideally this should ensure that if one AZ goes down, it should not effect the app because everything is spread across multiple AZs. But the recent AWS outage took the app down for a long time. I am not sure how this can happen. It would be great if someone can point out what went wrong. Major question here I have is how can I avoid this in future? I can setup app servers across different regions or even providers and use DNS for load balancing but what do I do with MySQL? Read Replicas will introduce some lag which I would want to avoid.

• Folder sync application which can sync over Internet (the other machine specified by an IP)?

  - by Adal

  I need to sync some folders between two Win 7 machines. While they are connected to the same LAN, they can't see each-other over Windows Networking since sharing is disabled on both of them (security reasons). Do you know any sync app which can work over IP? The folder I need to sync has 500,000 files in it (80 GB in total), so the sync app should be pretty efficient. At the moment I copy the files from one machine to the other over FTP, but it takes forever, since a separate connection is opened for each file. Or maybe you know some app which can efficiently transfer a large number of files between two machines on the Internet?

• Unreadable sectors reported by smartd, is it serious?

  - by stribika

  I have a RAID 5 array of 4 disks. In the last 2 days I began to see these messages in the log: Jun 13 23:01:05 localhost smartd[4537]: Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors Jun 13 23:01:05 localhost smartd[4537]: Device: /dev/sdb [SAT], 2 Currently unreadable (pending) sectors If I have 2 faulty disks then the array should not show all disks OK: md0 : active raid1 sdd1[3] sdb1[1] sdc1[2] sda1[0] 64128 blocks [4/4] [UUUU] Strangely there are no other problems just the log messages. I am worried because sda is new and I previously had problems with sdb. (Completely died but the guy who sold it to me fixed it somehow.) Am I in danger of losing data? What should I do now?

• Setting up central git repo on local Mac network

  - by Dashman

  We are a team of three, all working on our local machines on the same internal network. We will all be working on websites in local working copies of the same Git repo hosted on Github. We have an internal staging machine here (dev.internal), and I am looking for a way for us to be able to push to this machine. At each milestone in the development cycle. In essence, all I really want us to be able to do is add the dev.internal machine as a remote, and push to this whenever we are ready. Could somebody please point me in the right direction to get this set up?

• Is Joerg Schilling’s “sdd” a full replacement for “dd”

  - by fishtoprecords

  I was directed to post here, I started on Stackoverflow.... I'm trying to use 'sdd' on my Debian system, and can't get one set of options to work. They do work in 'dd' so I am wondering if I am specifying them incorrectly, or if sdd didn't implement them, or something else. What I want to do is sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 conv=sync,noerror if I leave out the "conv=..." option, it works, or at least starts copying data. sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 Can you shed a bit of light?

• How to deploy Windows-8 Enterprise Apps to other users?

  - by TToni

  Windows-8 (Metro) Apps can be installed using "sideloading", bypassing the Windows store in enterprise environments. In principle this is easy: Once you enabled sideloading (which is automatically done when a Win8-machine joins a domain), you can install a signed appx-Package through PowerShell with the "Add-AppxPackage" command. But there is a catch: The App is only installed for the user who executes the command and there is no "-Credentials" parameter! I can probably solve that problem in my specific scenario, where I deploy a self-developed app through TFS build to a virtual machine with a fixed demo user (by using remote powershell in combination with "Add-Job", which does take a credential parameter and because I know the given username and the password). But that is not true in an enterprise environment, where I want to distribute my App to thousands of users. Cracking all their passwords seems a bit over the top, so what would be the "correct" way to do this? I can't find any useful information from Microsoft about this, but maybe one of you already ran into this problem and solved it?

• The authenticity of host “host” can't be established

  - by Candroid

  I'm running a web app on a Linux server which connects to other servers. When I run the project on my Play framework on loclhost it runs fluently. When I run it on my Linux server I get the above message 3 times, one for each server. I read a post about it where it says that it is a man in the middle warning and if I write yes it should work. But though a write yes, nothing happens and the app doesn't run, and the error message keeps popping up. I tried creating private and public keys and add them to the authorized_keys file, but it didn't work either. What should I so to run my app?

• Has anyone found a (eg bash) shell terminal for Windows as good as the OS X one?

  - by Anentropic

  I am mostly using 'git-bash' which came with the Windows install of Git vcs. I think it is the same one that comes with Cygwin. It works fine technically but the UI sucks: have to right-click the title bar and go to Properties to change the window width most annoyingly... copy and paste and highlight with the mouse are equally cumbersome In contrast, the Terminal app that comes with OS X manages these with aplomb and makes it so much more comfortable to work with. You can even drag and drop a file on it and it will paste the file path in at your cursor! I have also tried: http://sourceforge.net/projects/win-bash http://www.steve.org.uk/Software/bash/ http://www.hamiltonlabs.com/cshell.htm None of these do copy and paste of text without cumbersome right-clicking. I am specifically looking for a Unix-flavoured shell in Windows so I don't have to use different shells between my home dev (Windows), the live server (Linux) or dev at the office (Mac). Yes I have Googled and haven't found one yet...

• Upgraded to Mountain Lion, now 127.0.0.1 is not resolving

  - by Shanimal

  I used to be able to type 127.0.0.1 (or my network IP 10.10.53.32) and it would resolve to my "default" virtual host. 127.0.0.1/~Shanimal and shanimal.dev both resolve to their appropriate folders. localhost and 127.0.0.1 give me a 404 - "Not Found The requested URL / was not found on this server." Basically, my "It works!" screen no longer works. /private/etc/apache2/Shanimal.conf: <Directory "/Users/Shanimal/Sites/_www"> Options Indexes Multiviews AllowOverride AuthConfig Limit Order allow,deny Allow from all </Directory> hosts: 127.0.0.1 localhost 127.0.0.1 shanimal.dev

• Is there an application that will move an active window to the system tray without minimizing it

  - by Robert

  I have an active application (lets say an instant messaging client) whose buddy list I have up (active) on one side of my screen at all times in Windows 7. I would like to remove that icon from the taskbar either by moving it to the system tray (as happens when the app is minimized) or by just removing it altogether. To be clear: I do not want to minimize the window to the system tray (as described in Windows app to hide application from taskbar) I want to keep the window its NORMAL size and location and just get rid of the taskbar icon for the app. I'm looking for any tool, third party, native, registry hack, to accomplish this.

• Ubuntu USB flash boot drive gets spontaneous "Unhandled sense code" error and causes drive to switch to Write protected

• How does Office 2008 for Mac store its Recent items?

  - by zenopolis

  I don't have access to Office 2008, but require the information for a project I'm working on. I'm mainly interested in Word, Excel and Powerpoint. This is the information I have gathered so far... The preference file is: ~/Library/Preferences/com.microsoft.office.plist The property keys take the form: 2008\File Aliases\{APP}{n} 2008\MRU Access Date\{APP}{n} where {APP} represents an Office application, and {n} represents a number starting from 0. The applications are represented by the following values: MSWD (Word) XCEL (Excel) What value represents PowerPoint? In the property list I've seen, the numbers represented by {n} range from 0-10 (11 items). Is 10 the limit? or is this unrestrained? Finally, I've noticed that Office 2011 does not add its Recent Items to the Apple System menu: Apple > Recent Items Is Office 2008 the same?

• Possible to run system-config-network during %post kickstart?

  - by tore-

  Hello, I'm currently trying to figure out a smart way to set IP, hostname, gateway and DNS settings during a kickstart (with user input during the kickstart). Doing this with firstboot after the install is not acceptable, so this must be done during %post. I've tried to run the system-config-network tool during post in tty6: #!/bin/sh chvt 6 exec < /dev/tty6 > /dev/tty6 /usr/bin/system-config-network-tui This doesn't work since for some reason I'm unable to catch user input. I would prefer to use built in tools to change this during post, rather than write my own bash script to do this, since using the provided tools is less likely to break anything. Does someone done anything like this or similar, and made it work? Thanks

• Using design-patterns to transform web-service model classes into local model classes and vise versa

  - by Daniil Petrov

  There is a web-application built with play framework 1.2.7. It contains less than 10 model classes. The main purpose of the application is a lightweight access to a complex remote application (more than 50 model classes). The remote application has its own SOAP API and we use it for synchronization of data. There is a scheduled job in the web-app which makes requests to the remote app. It gets bunches of objects from the remote model and populates corresponding objects of the local model. Currently, there are two groups of classes - the local model and the remote model (generated from wsdl schema). It is not allowed to make any modifications to the remote model. Transformations are being made in the scheduled job class. When it gets objects from the remote app it creates local objects. Recently, it was decided to add a possibility to modify the remote objects. It requires more transformations on our side. We need to transform from remote to local model when reading objects and from local to remote when changing objects. I wonder if this would be possible to use some design-patterns to reduce a number of transformations?
