  • Is it possible to have zsh+keychain+tmux not ask for keys?

    - by Wayne Werner
    I'm using tmux and zsh, and I've recently been learning about ssh-agent and keychain. From the manpage for zsh, it says that it will source .zlogin only if the shell is, well, a login shell. Following advice I read, I stuck keychain --clear in my .zlogin, which worked perfectly. When I logged into the box I had to unlock my key. However, each time I create a new window in tmux, it clears/makes me re-add my key. This is a little annoying... but I can understand it if, in fact, each new tmux window is a login window. I haven't been able to find much help outside of the manpages on this topic. So is each new tmux window a login shell, or is there any way that I can make it not clear my keys only when I create a tmux window?

  • Is it possible to listen to relational database update?

    - by Morgan Cheng
    Is it possible to listen to relation database update? For example, my web app want to send data update to client through Comet technology. I can have the program to poll the database periodically, but that would not be performant and scalable. If app can hood to a "event handler" of database, then app can get notification every time given database table data is updated. This sounds more promising, but I didn't find any concrete example for it. This is listener pattern. Does common relational database support such feature?

  • What are the best possible ways to benchmark RAM (no-ECC) under linux / arm?

    - by moul
    I want to test integrity and global performances of no-ECC memory chips on a custom board Are there some tools that run under linux so I can monitor system and global temperature in the same time ? Are there some no-ECC specific tests to do in general ? EDIT 1: I already know how to monitor temperature (I use a special platform feature /sys/devices/platform/......../temp1_input). For now : wazoox : it works but I've to code my own tests Jason Huntley : ramspeed : does not work on arm stream benchmark : it works and is very fast, so I'll look if it's accurate and complete memtest : I'll try later, since it does not run directly from linux stress for fedora : I'll try later too, it's too problematic for me to install fedora now I found this distribution : http://www.stresslinux.org/sl/ I'll continue to check tools that run directly under linux without too big dependencies, after I'll maybe give a try to solutions like stresslinux, memtest, stress for fedora. Thanks for you answers, I'll continue to investigate

  • Is it possible for the Subversion Apache module to serve html files with an html content-type without using the svn:mime-type property?

    - by Martin Pain
    I am aware that if you set the svn:mime-type Subversion property on a .html file to text/html then when viewing the file in a browser through the Subversion module in Apache httpd it will be served with a Content-Type: text/html header, enabling the browser to render it as HTML rather than plain text. However, I am looking for a way to do this without using the svn:mime-type property. I'm aware that you can configure your svn client to automatically add the property - this is not what I want, as I do not want to ensure all users have these settings. I'm also aware that I could create a pre-commit hook that rejects the commit if the properties are not set, in order to force users to set the property - I might fall back to that, but I'm looking for something less intrusive. I'm also aware that I could use a post-commit hook to add the properties automatically on the server-side. I'd rather not do that (as users then have to update immediately after their commit, and it's not trivial to write) - I'm looking for a better alternative. Perhaps something with rewrite rules in the Apache server?

  • Is it possible to check a MP3 for data corruption?

    - by Chris
    I was listening to some older mp3s today and I released that some of my songs have pops and cracks in them. I assume this means that the file has some bad blocks. Is there software/script/etc that I can run on my entire library and find the music with these artifacts? Thanks!

  • How is it possible for mod_wsgi to be compiled against Python 2.7.3 but use the 2.7.2 runtime?

    - by Ian William Kohl
    The following is what appears in my error_log: [Sat Nov 17 23:13:14 2012] [warn] mod_wsgi: Compiled for Python/2.7.3. [Sat Nov 17 23:13:14 2012] [warn] mod_wsgi: Runtime using Python/2.7.2. If I check my $PATH variable and even in /etc/paths, /usr/local/bin (which contains Python 2.7.3) comes before /usr/bin (which contains Python 2.7.2). Is there some other path that I'm missing out on? How can I get the correct runtime to be used?

  • Is it possible to upgrade using the Windows Server 2012 evaluation?

    - by Cerebrate
    I've got a Windows Server 2008 Standard installation here that I'm trying to upgrade to Windows Server 2012 Server, using the evaluation version. (The scenario is essentially that I need to test the upgrade, and specifically the upgrade process, before we spend the money on going ahead with the actual upgrade.) When I try to upgrade, it fails with the message: "Windows Server 2008 Standard cannot be upgraded to Windows Server 2012 Standard Evaluation (Server with a GUI). You can choose to install a new... (etc., etc.)" Is this (non-upgradability) a known limitation of the evaluation version? (Unfortunately, I haven't found a clear answer on this point.) And if not, any thoughts on where else I might look for the problem and solutions to it?

  • Is it possible at all to install Ubuntu 10.04 on Windows 7 (64-bit) using its Virtual PC?

    - by Jian Lin
    It was said that Win 7's Virtual PC is not suitable for installing Ubuntu 10.04... Is there any method at all that it will work? The following is the scenario I ran into: The first time Ubuntu 10.04 installation CD-R boots up, it asked for the Language, and "Install Ubuntu" and then the screen has vertical green bars and then the VPC just closed. The 2nd or 3rd time it booted up, there is no asking of Language or "Install Ubuntu" and just shut down the VPC, sometimes with vertical green bars. I even created another new hard drive and same thing happened. And created VPC 02, and same thing happened. Created VPC 03 with a fixed hard drive size of 60GB and same thing happened.

  • Windows/C++: Is it possible to find the line of code where exception was thrown having "Exception Of

    - by Pavel
    One of our users having an Exception on our product startup. She has sent us the following error message from Windows: Problem Event Name: APPCRASH Application Name: program.exe Application Version: 1.0.0.1 Application Timestamp: 4ba62004 Fault Module Name: agcutils.dll Fault Module Version: 1.0.0.1 Fault Module Timestamp: 48dbd973 Exception Code: c0000005 Exception Offset: 000038d7 OS Version: 6.0.6002.2.2.0.768.2 Locale ID: 1033 Additional Information 1: 381d Additional Information 2: fdf78cd6110fd6ff90e9fff3d6ab377d Additional Information 3: b2df Additional Information 4: a3da65b92a4f9b2faa205d199b0aa9ef Is it possible to locate the exact place in the source code where the exception has occured having this information? What is the common technique for C++ programmers on Windows to locate the place of an error that has occured on user computer? Our project is compiled with Release configuration, PDB file is generated. I hope my question is not too naive.

  • Is it possible to dynamically set a static string during compile?

    - by LonnieBest
    I'm trying to dynamically create a connection string during compile time: public static string ConnectionString { get { string connectionString = @"Data Source=" + myLibrary.common.GetExeDir() + @"\Database\db.sdf;"; return connectionString; } } I keep running into type initialisation errors. I was trying to avoid having to set the connection string for all applications that user my code library. The location of the database is different for each project that uses the library. I have code that can determine the correction string, but was wanting run it during compile time. Is this even possible?

  • Is it possible to add a third monitor via ZoneScreen?

    - by slapout7
    I have a dual-monitor setup that I’d like to add a third monitor to. I’m trying to use ZoneScreen and another computer to do this. When I run ZoneScreen it only gives me the option to send the video from one of the two already existing displays to the other computer. How can I get it to create and send a third display?

  • Possible to use DRBD on two ESXi virtualized servers?

    - by chen
    I have two servers (attached disks have been set up as hardware RAID1 for disk device level failure resilience). Here is the setup in my mind: 1) Install ESXi on each of the physical server, M1, M2; 2) Start one VM on each of the ESXi virtualized physical server V1, V2; 3) Install the DRDB drivers within V1 and V2. Essentially, this is a "virtualizing machine running DRBD in the VM's instead of bare metal hardware" idea. My question is whether the above setup can achieve the same "networked RAID1" goal that DRDB can achieve in the bare-metal physical machines (http://www.drbd.org/). Thanks. [EDIT] I found this (http://serverfault.com/questions/49305/drbd-experimentation-and-virtualization) is a similar question, but the answer does not seem to be firmative enough for me to follow.

  • What's the max Windows 7 access possible to restrict tampering with single service?

    - by Crawford Comeaux
    I'm developing an ADHD management system for myself. Without going into detail (and as silly as it may sound for a grown man to need something like this), I need to build a me-proof service to run on my Windows 7 Ultra laptop. I still need fairly complete access to the system, though. How can I set things up so that I'm unable to "easily" (ie. within 3-5 mins without rebooting) stop the service or prevent it from running?

  • Multithreaded FTP upload. Is it possible?

    - by Arty
    I need to upload multiple files from directory to the server via FTP and SFTP. I've solved this task for SFTP with python, paramiko and threading. But I have problem with doing it for FTP. I tried to use ftplib for python, but it seems that it doesn't support threading and I upload all files one by one, which is very slow. I'm wondering is it even possible to do multithreading uploads with FTP protocol without creating separate connections/authorizations (it takes too long)? Solution can be on Python or PHP. Maybe CURL? Would be grateful for any ideas.

  • Using Puppet, is it possible to define which plugins gets sync with a particular client?

    - by luckytaxi
    I have a plugin that gets pushed to all clients. However, I have one that's specific to a particular module, hence I don't want it synced with all my clients. My generic plugin is stored in /etc/puppet/modules/custom/lib/facter but I have a plugin stored inside a module that seems to be pushed to all clients regardless if the host inherits the class or not. Location of module: /etc/puppet/modules/apache/lib/facter/SAMPLE_PLUGIN.rb

  • In your ssh config is it possible to have one host entry for multiple machines on the same domain

    - by Joshua Olson
    I'd like to be able to do something like Host * HostName *.mydomain.com ... So I can type something like ssh test ssh ci ssh dev Instead of having to type ssh test.mydomain.com ssh ci.mydomain.com ssh dev.mydomain.com Right now I have separate entries for each one, but we have dozens of machines, so I'd rather have a default rather than have to duplicate everything so many times.

  • Is it possible to create a Windows shortcut using PHP?

    - by Drarok
    I'm writing a script to tidy up a bunch of media spread across my hard drives, and it works pretty well so far at home (on my Mac) as I use symlinks in a directory to give the impression that everything is organised in one location, whilst the actual data is spread across the 4 drives. Unfortunately, I have to use Windows at work, and of course there's no symlink support there until PHP 5.3 (and I assume that requires Vista as that's when the command-line tool "mklink" first appeared). As a workaround, I considered creating a shortcut, but I can't find a way of doing it. Is it possible, or is there a better solution I've not considered?

  • jQuery is it possible to concatenate two selector variables?

    - by Kris Hollenbeck
    Lets say I have two variables defining separate selectors, for example... var parent = $('.parent'); var child = $('.child'); And I want to create a something like the following... $(parent + child).click(); Which should be equivalent to doing this (if it was correct syntax)... $('.parent .child').click(); This may not be best practice, however I am curious if it is possible. Thanks for your help in advance.

  • Databinding in windows forms on an object graph with possible null properties?

    - by Fredrik
    If I have an object graph like this: class Company { public Address MainAddress {...} } class Address { public string City { ... } } Company c = new Company(); c.MainAddress = new Address(); c.MainAddress.City = "Stockholm"; and databind to a control using: textBox1.DataBinding.Add( "Text", c, "MainAddress.City" ); Everything is fine, but If I bind to: Company c2 = new Company(); c2 using the same syntax it crashes since the MainAddress property is null. I wonder if there is a custom Binding class that can set up listeners for all the possible paths here and bind to the actual object dynamically when/if I sometime later in the application set the MainAddress property.

  • Is it possible to iterate all the OutputCache keys?

    - by Deane
    Is it possible to iterate the OutputCache keys? I know you can remove them individually via HttpResponse.RemoveOutputCacheItem(), but is there a way I can iterate all the keys to see what's in the collection? I searched through Object Viewer, but didn't see anything. Worst case, I can maintain my own index. Since I'm doing everything by VaryByCustom, they get "fed" through a method in global.asax. It just strikes me that there has to be a more elegant way of doing this.

  • Is it possible to copy a set of files, but automatically skip if file already exists?

    - by awe
    I know that the copy command has an option to automatically replace a file if it already exists, but I want to know if it is a way to copy the files only if they not already exist (/Y). I do not know the actual file names in the batch code, as I copy from the source using wildcards in the copy command: copy *.zip c:\destination The reason I want this instead of automatic overwrite is that the files are large, and to skip existing would save a lot of execution time.

  • Is it possible to create an SFTP drop box?

    - by Jordan Reiter
    I have a Windows server with folders accessible via SFTP (server is running OpenSSH). scp is blocked. I would like to copy files from a Linux server to the Windows server. SFTP seems like a good option. Ideally I'd like something similar to an FTP drop box, so that the Linux box could just copy files directly over to the Windows box. I'm also open to any solutions to this that would allow me to copy the files while offering the least amount of hassle. The language I'd be using on the Linux box is python; not sure if that factors in or not.

  • Is it possible to map a root domain URL to a Grails' controller?

    - by firnnauriel
    Let's have an example: A grails project, myproj, is deployed in Tomcat 6. It can be accessed anywhere thru this link: http://www.mycompany.com/myproj. Let's say we purchase another domain, http://newcompany.com, and we would like to point it to http://www.mycompany.com/myproj/url. If I go to http://newcompany.com/12345, it should be the same as doing http://www.mycompany.com/myproj/url/12345. Can anyone tell me if this is possible? How to implement it (change Tomcat 6 config, add code in UrlMappings.groovy)? Thanks in advance.
