  • Hide non printable characters in vim

    - by knittl
    Vim shows non-printable characters prefixed with a ^ (for instance ^@ for a NUL byte). I have a column based file containing both printable and non-printable characters which is difficult to read, since each non-printable character shifts all remaining columns one character to the right. Is there a way to hide non-printable characters or simply display a placeholder char instead? I also don't mind having every character be represented by two characters.

  • Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

    - by Warren P
    Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

  • How to make a persistent acknowledgment in Icinga/Nagios?

    - by blerontin
    I am using Icinga (Nagios fork) to also monitor uptime of external hosts and services. Currently when looking at the "Critical" count I find it difficult to decide if an internal service is affected (I should take immediate action) or an external service (I just acknowledge the problem). Is there a way to keep a problem acknowledgement for future down-times of the checked host/service? Is there some way to auto-acknowledge the state change of external hosts/services?

  • Want to create an SQL function that removes table row duplicates [migrated]

    - by Hoser
    I'd be following the procedure outlined here (unless of course someone has a better way to do it), and I'm wondering if I could just have some help being pointed in the right direction on how to start. Basically I need help first on HOW to create functions, and general tips on making it adjustable for varying number of columns etc. This may be a very complicated task, as I have no previous experience making SQL functions, so please let me know if this is a difficult task for an SQL noobie working with MS SQL 2005.

  • Secure linux distro that sends traffic through Tor

    - by gravestone
    I'm looking for a live Linux distro that is secure and preserves my anonymity online. For what I need, Tor seems to do the job – but such software requires configuration that someone who is not knowledgeable in how it works might find difficult. I was looking at 'Lightweight portable security' but it does not specify whether it sends all traffic through Tor. Does anyone know more information about it and/or any other such live Linux distro?

  • Initrd and Initramfs

    - by nitins
    I have read about the differences between the two from stackoverflow. But I am still finding it difficult to understand tmpfs and the real advantages of initramfs over initrd. I find that on RedHat EL 5 or Ubuntu 12.04, I have only initrd files in /boot. However RedHat EL 6 has both intird and intramfs files. Does that mean only Redhat 6 has implemented intiramfs and we still have initrd image there?

  • Tool to Set a Hotkey to Adjust Overlay Surface Gamma

    - by Synetech inc.
    I am looking for a (Windows XP) utility (preferably a standalone app) that can let me set a hotkey to adjust the gamma (and hopefully other color settings) of the overlay surface. ATI Tray Tools does not have the ability to bind the overlay color adjustments to the overlay. I’ve asked him about it and he said it was difficult to implement or something (he was kind of vague). The ATI Catalyst drivers do not have a hotkey function for the overlay tab either. Can anyone help?

  • Refurbished vs. Used monitors

    - by Timur Sadykov
    I am looking for additional monitor, I'm trying to save some money by looking on used and refurbished ones. Used monitors are usually noticeably cheaper, but it is quite difficult to find something close to the desired model. Their condition also vary significantly. Refurbished ones eliminate these problems for some additional money. Is there anything to look out for with refurbished monitors? Do many of the have lots of broken pixels etc?

  • Scrolling content in a kindle book

    - by Dave
    I'm wondering if anyone is aware of a way to scroll content in a kindle book. I thought I had the problem solved by using calibre but I quickly discovered that since the content is DRMed, I'm not allowed to read the book with this reader. lame The specific book I'm reading has code examples in it, but it is difficult to follow them without being able to specifically scroll through the examples. This doesn't even touch on the fact that the code content is also poorly formatted.

  • How to discover which name/address connections from one network to another uses?

    - by Jader Dias
    In MySQL you have to authorized a user based on the name of the origin network. From my network to a remote one all connections appear as sent from mail.mycompany.com. But connections to another remote network it appears with a different origin. How to discover which name/ip it is using? I tried tcpdump and netstat in the destination but it is difficult to find my connection among billions of others. In my case the destination is a Windows Server 2003

  • SVN over VPN on Fedora 10

    - by bryan
    I would like to be able to pull changes on a remote server from an SVN server on a local development box. The SVN port is closed to the WAN but available via our LAN and we have a VPN setup locally. Is it difficult to setup the remote server to use VPN to connect to the remote SVN server and update code? If possible, how/where can I find out how to do this? Thanks in advance.

  • conemu start a given console with hotkey

    - by Car981
    How could I assign a hotkey of my choice to start c:\cygwin\cygwin.bat ? Similarly, but a bit more difficult, how could I start c:\dir1#VAR#\dir2\test.bat, where #VAR# is the name of a directory that varies, and the last (in alphabetical order) of all #VAR# should be chosen ? So just to be clear, if c:\dir1\A\dir2\test.bat and c:\dir1\B\dir2\test.bat exist, the console that should be opened when the hotkey is pressed is: c:\dir1\B\dir2\test.bat. Thanks

  • Tool to collect stacktraces in server logs

    - by hstoerr
    Is there a tool collect and count all different stacktraces in a bunch of server logfiles? Sometimes you have just too many stacktraces that repeat over and over. So it can be difficult to spot different problems between the stacktraces. So the idea would be to have a tool that looks for stacktraces, compares them and counts them. It would be nice if the tool could ignore minor differences (e.g. $Proxy150.dispatchCalls() versus $Proxy25.dispatchCalls() ).

  • Execute a program by double-clicking the taskbar and/or the desktop, Windows 7

    - by JoePerkins
    It would be so useful, and not very difficult, because in fact I have Directory Opus installed (a very powerful windows explorer alternative) and it does exactly that, but only by double-clicking the desktop, not the taskbar. Similar options with middle-click would also be nice, such as scrolling the taskbar (maybe cycling directly through the Alt-Tab window). 7 Task Tweaker is close to this, actually, but it doesn't do what I would like.

  • Second portable monitor for a laptop

    - by user2630
    I'm away from my home office fairly regularly but I find it difficult to really settle to productive coding without my custom 4-screen custom built PC. My laptop (a slightly ageing HP Pavilion with a 1440 x 900 display) would really benefit from a portable monitor to plug into the vga port. Is there any suitable products out there which offer an easily luggable lightweight monitor which would fit in my laptop, offer reasonable resolution and response, and significantly enhance my screen real-estate?

  • Can a virus attack my BIOS to disable the DVD drive?

    - by user636547
    A friend's laptop DVD drive is suddenly no longer detected. It's going to be difficult to walk him through going into the BIOS (he's not local). I wonder if it is even worthwhile i.e. whether the BIOS settings can be corrupted by a virus. Are BIOS settings formatted in a standard way such that a virus writer would know what to alter? FYI, he did reinstall the OS and the drive is still not detected.

  • Determining temporary Internet file type (Chrome)

    - by DJoyce
    My broadband speed is sometimes lacking, and therefore it can be difficult to view Flash streams of programmes. So my idea is to start a Flash stream, let it run to completion no matter how long it takes, and then view the temporary .swf file. I've discovered the location of my Google Chrome temporary files. However, there is no file type associated with these files. Therefore, I'm wondering if the idea above will work, and how can I retrieve only .swf files?
