• Hidden bootloader

  - by Jack

  I need a bootloader that will work as described: I want my computer to boot Windows, that is my main OS installed on a primary bootable partition. However, I'd like to have a 2-3 second span with blinking cursor, before Windows starts. If I press any key in that period it should launch Ubuntu from a small Truecrypt-encoded partition, upon providing a correct password. In other words I'm looking for a hidden bootloader that would expose itself only when a key is pressed during a certain time. Do you happen to know anything like that?

• Map keys in Vim

  - by efficiencyIsBliss

  I want to map e to mean end of line. I tried the following mapping in my vimrc: map $ e $ is the default end of line command. However, this doesn't work. I'm wondering what the problem is. Also, I want to map Alt+right/left arrow to navigate words. So, for example, Alt+right arrow would take me to end of word. This command is currently mapped to e. Any tips on how I would go about doing this? Thanks!

• How to rename multiple files by replacing word in file name geting from the shell script variables?

  - by fy6877

  This question like this thread. How to rename multiple files by replacing word in file name? My example is more complex than the above topic. The two variables are $name and $ newname getting from the shell script other location. $name and $ newname may have the unicode words or special symbles like []<?...etc,so could anyone help me to provide a method to add a part of script in shell scrit to solve file name replacing question. BTW,I try to type two kind of commands to change the part of file name, but it can't work. rename.ul '$name' '$newname' /home/fy6877/test/final/* ls /home/fy6877/test/final/|xargs -I$ rename.ul '$name' '$newname' $

• Windows 7 CD keys, are they interchangable?

  - by unixman83

  I am talking about during installation. Using regular licensing, not volume licensing. Amongst OSes of the same class, are CD keys interchangeable or are they locked to a specific subset of CDs? In other words: If I have 10 legally purchased copies of Windows 7 Professional, can I throw out the discs for all but one? And all the CD keys will work? UPDATE: How about for service packs (when they come out). If I have Windows 7 Professional SP1 and a Windows 7 RTM original? Do they change CD keys between service packs?

• I cannot access my flickr account

  - by AtanuCSE

  I was using Google account to log in to my Flickr. After several days, I entered into the Flickr account and found out that Flickr is moving into only Yahoo login. So I tried the Google login and it shows This account is not connected with any Yahoo account. Sign up for new........ or use existing etc... Can't remember the exact words. So I provided my Yahoo mail credentials. Now every time it is giving me a brand new account, rather taking me to my previous Flickr account. I can view the previous account photos, but After going there, it treated me as a outsider. New account showing me that I've not uploaded any photo. What's wrong? How can I connect with my previous account?

• Automate opening HTML and printing to PDF

  - by craigpatik

  I need a way to automate the following process in Windows 7: Open an .html file in Internet Explorer Print to PDF Save the PDF with a patterned file name (i.e., original_name_YYYY-MM-DD.pdf) Ideally, I could drag and drop several files or open a whole folder of files at once and a PDF would be created for each one. A command line solution is also acceptable. The files have to be opened in the browser because parts of the page are rendered with JavaScript on page load. In other words, if you simply right-click on the file in Explorer and choose "print", the resulting file is not the same because the JS didn't run. If it helps, Internet Explorer can be set as the default browser, and a PDF printer can be set as the default printer.

• Running a script at startup as root?

  - by Usman Ajmal

  Hi i developed a script which I set to run at startup i.e. when the Desktop appears. In the script I mounted a partition using sudo mount /dev/sda1 /mnt &> result.txt After executing script a file named result.txt was created which contained sudo: no tty present and no askpass program specified In other words the mounting failed. If I run the script using sudo ./myProgram i don't face this problem and the drive gets mounted successfully. Any suggestions please....

• Receiving a notification on a Cluster Group Failover

  - by Diego

  Hi all, I have several Windows Cluster set up and I have the need of keeping track of failovers. I'd need to receive a notification of sort whenever a group fails over. I've seen some examples around, but I can't rely on the approach of just sending a message whenever the resources are stopped/restarted as it would generate too many false alarms. In few words, I need to be notified if and only if the group really fails over. I was thinking that probably the best way is monitoring the System Event Log, but, if possible, I'd prefer not having to write a script/program from scratch for this issue. Is there any script/product that already does it? Thanks.

• OpenOffice - alternative paragraphs (two PDFs, one source)

  - by RedGrittyBrick

  I use OpenOffice to produce a document in PDF format. This document is occasionally revised and reissued. I now need to produce a variant of this document with a small number of paragraphs replaced by other paragraphs. I would prefer to avoid maintaining two separate documents where 95% of the text is the same. In other words, from one ODT file I would like to be able to produce two PDFs with slighly differing content. Are there some OpenOffice features I could use that would help with this?

• set chars to uppercase between parenthesis

  - by emzap79

  let's assume in vim I have following lines: all what (strong) people have to do is pushing (heavy) weights over (and over) again in order to gain muscles and I need to convert words inside parenthesis to uppercase, what is the most convenient way to do so? How do I tell vim it needs to select everything to the first (!) closing parenthesis? So far I came up with :%s/\s(.*)\s/\U&/g unfortunately this will uppercase everything between 'strong' and 'heavy' which is not what I want. Any chance to tell vim it should select the chars to the next closing bracket only? (sorry for the silly example, couldn't think of something more sophisticated... or at least vim related... huh)

• Only allow root to change filesystem

  - by Uejji

  The VPS I manage uses a simple hard link rsync archive daily backup system saved to a loop file. This is great, because each backup only takes up as much space as what has changed each day, and all user/group permissions are kept. I would like to give users direct access to their home directories in each backup, but I'm worried about intentional or accidental backup data destruction, as how it stands now users can actually change, destroy or add to backed up data they originally owned. I've been looking for a way to mount this filesystem similar to an ro mount option, but something that would still allow rw access to root, but I've had absolutely no luck. In other words, I want users to be able to view and copy their backed up data without actually being able to change it, and have that data maintain the original permissions. I've got no real preferences as far as filesystem, as long as it's a standard unix filesystem that can preserve permissions, support hard links and deny write access to users without actually stripping the w permission from everything.

• Fresh install of nginx causes browser to download index.html instead of opening it

  - by 010110110101

  When I view this in Chrome, http://localhost:90 the file is downloaded instead of displayed in Chrome. This question has been asked a lot of times on SO, but about index.php files. My problem is a plain jane HTML file, not a PHP file. That hasn't been asked yet. I was hoping the solution would be similar, but I haven't been able to figure it out. Here's my example.com.conf: server { server_name localhost; listen 90; root /var/www/example.com/html index index.html location / { try_file $uri $uri/ =404; } } My index.html file contains only two words, no markup Hello World I think it's the mime.types. The mime.types file has the entry for html in it. This is a fresh nginx install. nginx -t reports "test is successful"

• How do I trap the mouse pointer within a VirtualBox Guest OS?

  - by Samuel

  I'm on a Mac Mini 2011 with VirtualBox installed. I have Windows 7 running as a Guest OS. My question: How do I "trap" my mouse pointer within Windows? In other words, I don't want my mouse to move outside to the Host OS. Ideally, I would be able to press the Host key to "untrap" my mouse. The purpose: I'm playing Warcraft 3 in the Guest OS and I can't scroll the screen since the mouse keeps jumping to the Host OS instead of scrolling the screen. This happens even in full-screen mode.

• Is there a software like AutoCAD, but only 2D, not 3D?

  - by Saeed Neamati

  I love AutuCAD. It's powerful, easy to use, and fits engineering mind. It rocks when you want to draw 2D diagrams and shapes and one the cool features I like about it, is its snapping power. You draw a simple rectangle, then you can very easily create a circumscribe circle around it. However, new version of it are becoming really heavy (in size) and need high tech hardware, because of its powerful 3D capabilities, and rendering engines coming with it. I only want the 2D part of AutoCAD. Is there any software out there, which resembles AutoCAD (like having a console, where you can type L and get the line tool, or having snapping capability, etc.), but is small in size? In other words, what software can be named as AutoCAD 2D alternative?

  How can I parse data from inside a tag with Applescript?

• How to Reset Windows 7 to its default font for the whole system?

  - by Fellknight

  This might sound a little bit silly but please bear with me. Somehow I changed my default display font, the one that Windows uses for system dialog boxes, accept/cancel buttons, pretty much everything in the system (it even goes as far as to change how my the text in my web browser appears). Now everything that it's affected looks like under the effects of the bold button in office (very black and very thick words). This is an inconvenience for example on some mail accounts who use this effect to display unread messages. Is there any way to return it to its default state, non "bold" typography for the whole system?

• Minimize writes to SSD disks with Windows 7

  - by mark

  Most people use their SSD as their primary system installation disk with Windows 7. W7 already has a lot of optimizations for SSDs, both in terms of performance and lifetime. Minimizing writes increases the lifetime of SSDs, so post each suggestion as an answer and let others vote on them. Update: I'm not sure anymore that minimizing writes is a good thing [tm], hard facts that SSDs will degrade within a noticeable time are missing and it seems this it can create a bit FUD about the functionality of the SSD. In other words: I question the usefulness of my wiki question.

• Spacebar on Samsung Series 7 Chronos Not Working

  - by Samg

  The spacebar on my Series 7 Chronos does not register half the time. I'll be typing along and my words end up lookinglikethis. After further investigation, I noticed the spacebar does not response when pressed at the edges. Basically, the areas under the "C" key and the "M" key do not respond to a press It's weird, the bar physically "clicks" down (like it should), but does not register. No matter how hard I press, It won't register in that area. I noticed some complaints online about a 'sticky' or 'loose' spacebar, but they didn't mention it not registering. We took it back to the store we bought it at and they noticed the same problem on the floor model. Does anyone know how to fix this?

• Apache2: How do I restrict access to a directory, but allow access to one file within it?

  - by Nick

  I've inherited a poorly designed web app, which has a certain file that needs to be publicly accessible, but that file is inside a directory which should not. In other words, I need a way to block all files and sub-directories within a directory, but over-ride it for a single file. I'm trying this: # No one needs to access this directly <Directory /var/www/DangerousDirectory/> Order Deny,allow Deny from all # But this file is OK: <Files /var/www/DangerousDirectory/SafeFile.html> Allow from all </Files> </Directory> But it's not working- it just blocks everything including the file I want to allow. Any suggestions?

• Very small computer for note-taking, with full-size keyboard

  - by Reid

  I am looking for a very small, lightweight computer with a full-size keyboard for taking text notes. Ideally it would be 500g or less including batteries for 16 hours of use. And writing text is the only use - a typewriter, if I could find one light enough, would be just fine. [I realize this is not the place for product recommendations, and that's not what I'm looking for. Rather, I have no experience in this space, so what I'd like is to understand what kinds of equipment are available and what are the right keywords to plug into Google/eBay/etc. In other words, help me learn enough to do a worthwhile search.]

• Reverse Proxy Server SSL?

  - by valveLondon

  Context We currently have an Apache web server in the DMZ set up as a reverse proxy and load balancer for two machines running Windows Server 2008 (IIS) inside. The Apache server has a genuine SSL certificate and serves up both http and https, however, the balancer members in the load balancing section are set to: BalancerMember {https://server1} and {https://server2}. The IIS web servers have self-signed certificates in order to respond to the https requests. My question: Do we need to forward any requests from Apache (in the DMZ) to the inside using SSL? e.g can the reverse proxy forward the requests using HTTP? and if so, why would I choose to forward them with SSL? (how secure is the http line between the dmz and the inside); In other words, can I totally disable SSL on my inside web servers?

• Combining multiple linux boxes and create VMs out of it

  - by NS Gopikrishnan

  I am new to virtualization. I am running on ubuntu. I have a set of linux machines (5 to 6 machines). Which I want to combine as a single resource pool and on demand create multiple virtual instances of machines out of it. This is comparable to what VirtualBox does in a single system. I stumbled across many key words: Xen, Eucalyptus, OpenStack etc. But things are very vague as to which will help me achieve this requirement. Any help will be appreciated :) Thanks in advance!

• Misbehavior in regular expression in VIM

  - by poissonbreaker

  I am having a problem with a regular expression on vim. I have a pattern as follows: http:\/\/\(\w\+\.\?\)\+ [matches http://(AS MANY WORDS FOLLOWED BY DOT OR NOT ENCOUNTERS) e.g. http://wd1.wd2.com] I have a text as follows: http://wd1.wd2.com/wd3 I am trying to make this substitution on it: s/\(http:\/\/\)\(\w\+\.\?\)\+/\1wd4.wd5.com and the result is http://wd4.wd5.com /wd3 (Notice the white space inserted at the end of the replacement) How can I avoid having this inserted space? I am afraid is a bug in the regexp engine but I am not sure.
