• How do I cut and paste between different files using emacs?

  - by JStarx

  I'm running OSX 10.6.8. Lets say I have two terminal windows open and in each window I begin editing a different file using emacs. In the first file I select some text and then copy it (M-w), and in the second file I then try and paste it (C-y). I thought this would paste what I copied from the other file but instead I get the error message "previous command was not a yank". Those commands work just fine for copying and pasting within a single file, how do I copy and paste between different files?

• How to access files on another local Windows 7 computer without using any native Windows features?

  - by user1356682

  I do not want to use any native Windows features, services, nor anything do to this. It needs to be a standalone program, with ZERO Windows dependencies. Just like TeamViewer does not use any native Windows features, so I want to be able to access files and folders in a standalone program. No remote desktop No VNC type programs No Windows File Sharing No Shared Folders in Windows No internet connection required It needs ability to view, edit, transfer files at normal network rates.

• debugging JBoss 100% CPU usage

  - by Nate

  We are using JBoss to run two of our WARs. One is our web app, the other is our web service. The web app accesses a database on another machine and makes requests to the web service. The web service makes JMS requests to other machines, aggregates the data, and returns it. At our biggest client, about once a month the JBoss Java process takes 100% of all CPUs. The machine running JBoss has 8 CPUs. Our web app is still accessible during this time, however pages take about 3 minutes to load. Restarting JBoss restores everything to normal. The database machine and all the other machines are fine, only the machine running JBoss is affected. Memory usage is normal. Network utilization is normal. There are no suspect error messages in the JBoss logs. I have set up a test environment as close as possible to the client's production environment and I've done load testing with as much as 2x the number of concurrent users. I have not gotten my test environment to replicate the problem. Where do we go from here? How can we narrow down the problem? Currently the only plan we have is to wait until the problem occurs in production on its own, then do some debugging to determine the cause. So far people have just restarted JBoss when the problem occurred to minimize down time. Next time it happens they will get a developer to take a look. The question is, next time it happens, what can be done to determine the cause? We could setup a separate JBoss instance on the same box and install the web app separately from the web service. This way when the problem next occurs we will know which WAR has the problem (assuming it is our code). This doesn't narrow it down much though. Should I enable JMX remote? This way the next time the problem occurs I can connect with VisualVM and see which threads are taking the CPU and what the hell they are doing. However, is there a significant down side to enabling JMX remote in a production environment? Is there another way to see what threads are eating the CPU and to get a stacktrace to see what they are doing? Any other ideas? Thanks!

• Windows 2003 routing by port

  - by vansickle

  I have remote Windows 2003 server with two network interfaces e.g. Cn1 and Cn2. I need that all traffic goes through Cn1 except for one port (for me it's 3389, rdp for administration) that works over Cn2. Currently when I setup all connections work through Cn1, I completely lose connection over Cn2 - and can't connect to server via RDP over Cn2. Now I used static routing based on my ip address (which can changed - so it's bad).

• How to enable/disable authentication without password when executing commands as superuser?

  - by 44taka

  On a Fedora 19 system which I set up for somebody a while ago I noticed that no authentication is required when commands are executed as the superuser. So, for example, when running Yum Extender, configuring the firewall or running some command with sudo in the terminal, I am not asked to provide a password. (With graphical applications the authentication dialog pops up for a few milliseconds.) For better security I would like to disable this automatic (authentication-less) assumption of superuser privileges. I do not remember if or how I enabled this authentication without a password. I might have enabled it for convenience for the non-pro user of this machine, but did not do any "fancy" things (like editing config files) to do so. I did not edit the sudoer file. I just checked that. I might have checked a "Do not ask for password again" checkbox or something similar. Whatever I did, I would like to undo it and enforce authentication for superuser tasks again.

• Word 2010, how to update protected document

  - by Seth

  The document has one "Section Break" with e.g. "Text Form Fields" above. To make this Form Field work properly I use "Restrict Editing", allow "Filling in Forms", "Select Sections" and then protect Section 1. Then "Start Enforcing Protection". Now when the document is protected above the Section Break you can't use CTRL-Aand F9 to make an update of the fields, etc. of the document below the Section Break. Is there any solution for this problem?

• iso9660 filesystem when remade with a slight change blows its size by 100M

  - by user1458001

  I have an iso 9660 filesystem image in which I need to edit just one file. I copied the files using cp -avf. When the files reach the destination, the sizes increase. That must be due to the increase in block size. But when I remake the iso9660 filesystem using mkisofs -J -U -r the sizes of the files remain the same and just a small editing in a file leads to a blow up of about 100M in the newly created iso image. I think I'm missing some option there, but I'm not able to find out in the manpage and google search. Some quick help would be greatly appreciated as I'm stuck. My host filesystem is ext3..if that's required.

• hosting website on a private network

  - by razor

  i'm currently running a website off 3 linux servers. I'd like to setup a private network and only allow port 80 traffic to one of the servers. I'd also like to setup a vpn so only I can access the servers via ssh or any port for developing/debugging. How hard is this to setup and what do I need to get? Do enterprise/commercial routers have vpn functionality built in? how do I handle DNS? eg- www.mydomain.com would need to point to the router, which forwards traffic to the webserver. Do I set the A record to the router, and somehow tell the router which server to send the http request to? And how would I make server1.mydomain.com resolve to server1 within the private network (without editing host files)? Would I need to run my own DNS (eg- powerdns?) to do this?

• Features of Emacs that are complementary to Vim?

  - by redacted

  I've been using Vim extensively for a while now, and I really enjoy working with it. However, I keep reading praises for Emacs. I've decided to take a look at Emacs to round out my knowledge of the Unix editors (not to mention Emacs keybindings are used extensively). But! I'm happy doing most of my daily work in Vim. So ideally what I'd like is to look at (apart from basics) are the gaps that Emacs can fill, or things that it can just do better than Vim. I suppose the canonical example is Lisp/Scheme coding in Emacs versus Vim. Where would you start tinkering with Emacs to really appreciate its power, and to get a good idea of how its approach to editing differs from Vim, and how the editors can complement each other? What would be a good introduction in the same vein?

• Are Uninterruptible Power Supply (UPS) at home really a worthwhile investment for home computing? [c

  - by Jian Lin

  Possible Duplicate: Is a UPS a good investment for a home machine? I have 2 Uninterruptible power supplies at home, but they seem to expire after 5 years or so. During this 5 years, it maybe saved the computer from turning off twice. But I wonder, I often save my documents every 10 minutes. So the most I can lose is 10 minute worth of work. Not to mention that, I may not be editing anything when the power is out. Also, when the UPS expires, one of them will give out beeping sound once in a while, probably signaling the changing of the battery. So I can either buy 2 new UPS or just buy 2 power outlets instead. 2 UPS, costing $160 to $250 roughly, can it be really worth it if it can save your computer from powering off for just 2 times? What are the alternatives?

• Configure different set of keyboard shortcuts for copy/paste in Photoshop (WIN)

  - by Diodeus

  Being left-handed, I use the mouse in my left hand. In most applications I use Ctrl + Insert or Shift + Insert to copy and paste (with my right hand). For some bone-headed reason, this is not supported in Photoshop, so I have to use right-click Copy sub-menus, which is a lot slower. Is there a way to configure Photoshop to use Ctrl + Insert to copy and Shift + Insert to paste? EDIT: I tried editing keyboard shortcuts, but it will not accept CTRL + INSERT as a valid entry. Is there no valid option for left-handed users?

• A "quick" vector editor (SVG) for Linux (for annotating images?)

  - by sdaau

  I often need to take a bitmap (.png) image, and draw some lines or text on top of it, and possibly export a new, thusly "annotated" image. I know I can basically do all this in inkscape - but inkscape is a complex program, and it needs almost a minute to start up properly on my PCs. So I was thinking - is there something like a "mini" vector editor for Linux, which would start up fast, and allow me to: Right-click, open an image in this editor program The program scales the active "document"/"window size" to the size of the image I can zoom in/zoom out (and possibly crop) the image I can add at least lines, boxes and text in different colors? A bonus for me would be to have the overlay graphics saved as SVG format, say with the same filename as the image - as in, "image.png.svg" being saved in the same directory where the original "image.png" is located (thus allowing opening and editing these "annotations" further, either in this editor, or possibly in inkscape). And another bonus would be the export of the annotated image to a bitmap. Anyone know about anything like this?

• VPN instead of KVM over IP? [on hold]

  - by Blazer

  I have a server colocated on datacenter.CentOS operating system. They use KVM-ip when I need remote hands. Somoene told me that login using that will allow administrators (if they want) to get disk encryption password or ssh root pass via KVM-ip(is that true ?). Someone told me I can use VPN to login to my server instead of kvm over ip. Anyone have experience with that ? Is that option valid ? Thank you
