  • Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

    - by jonathanconway
    I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

  • Printing perforated business cards

    - by Gio Borje
    I have a Brother MFC 440CN printer with the paper loaded underneath it. The problem with my stack of perforated business cards is that I can't print double-sided. The printer pulls the paper out from under its paper tray below and rolls it through the top for printing. With perforated business cards, they paper breaks at the perforations. Is there a method to preventing the slicing? Also, my printer also has some trouble pulling up the paper in general but I don't seem to understand why other than that the perforations break before the paper is grabbed for printing.

  • How to crash a program

    - by user2949019
    I have a program called BlueCoat Proxy installed on my school issued laptop that basically blocks every second website on the Internet, including stack exchange, YouTube and yahoo answers. I do not have administrator rights, nor can I delete anything in program files, I tried every possible method of obtaining admin rights. It is not accessible in task manager (it doesn't even appear there). I tried to close it with Windows command prompt through commands like 'taskkill' but it returns 'Access is Denied' (I'm only denied access with that program). Does anyone know a method of crashing a program with a batch file or VB program? I was thinking something like the ping command, though for a program. Maybe automating 1000 meaningless requests to the program? Your input on the subject matter is appreciated, however telling me that this is wrong or illegal is not.

  • How to batch rename files using bash

    - by Alex Popov
    I know there are lots of such questions, but I couldn't find one (or a combination of several), which describes the things I want to do. I think I need to use regular expressions, but I am not very good with that. I use zsh. I have a folder with files, which I want to rename: I want the files challenge1.rb, challenge2.rb, challenge3.rb, etc. to be renamed to c1.rb, c2.rb etc. Similarly task1.rb and similar must be renamed to t1.rb etc. sample_spec_c1.rb, sample_spec_c2.rb etc. must be renamed to c1_spec.rb, c2_spec.rb etc. So I guess I need some combination of regular expressions and iteration, but I don't know how to write the bash script.

  • Revision / backup software for folder?

    - by Gabriel
    I'm looking for a simple backup/revision software that will monitor a folder for new changes and make a backup of newly modified files? I have a folder with some text files, a few Word/Excel files and I'd like to keep backup files of them when they're modified. (It's no more than 50 mb). I'd like what Dropbox does but just locally (not to be stored on the cloud). Thank you. Edit: I'm on Windows XP. And I'm looking for a freeware app, if possible.

The CopyProfile seems to apply Administrator's settings on programmaticaly created accounts, but does not preserve local users settings accross installations.

  • pendrive automount not working

    - by Delirium tremens
    There are lots of ways to disable pendrive automount. I used one, but regreted, forgot which one and now need to reenable pendrive automount. It may have been a changed setting after pressing a button while booting Ubuntu or a deleted folder named something20090101 or 01012009something or whatever as long as it's a word and a date... If I don't want pendrive viruses, it's disable autorun, but keep automount enabled, right? blush

  • Matching digits in Notepad++ extended search mode

    - by ketchup
    Notepad++'s manual is rather vague on the special character for numerical used in extended search mode. It says: \d### - Decimal value (between 000 and 255) but literally entering "\d###" doesn't match anything. What I am trying to do is to replace if VarA == 12 VarB = 1 with if VarA == 12 Var12=1 VarB=1

  • Volume key occassionally changes relative volume in mixer

    - by bobobobo
    I find this a bit of a nuisance but I usually use the "volume up/down" key on my Microsoft ergo 4000 to change the volume of my system. The problem I'm experiencing is every so often, the volume of Winamp goes way down relative to the other apps in the mixer: So I don't always notice this right away, suddenly I can't hear Brandy warbling. And that makes me sad. Or mad. Or both. But it's a nuisance - is there a special key combination I need to avoid pressing to stop the mixer from imbalancing? Is there a way to disable this "app specific" mixer, because it is completely useless to me.

  • Mirror a Dropbox repository in Sharepoint and restrict access

    - by Dan Robson
    I'm looking for an elegant way to solve the following problem: My development team uses Dropbox for sharing documents amongst our immediate group. We'd like to put some of those documents into a SharePoint repository for the larger group to be able to access, as granting Dropbox access to the group at large is not ideal. However, we'd like to continue to be able to propagate changes to the SharePoint site simply by updating the files in Dropbox on our local client machines, and also vice versa - users granted access on SharePoint that update files in that workspace should be able to save their files and the changes should appear automatically on our client PC's. I've already done the organization of the folders so that in Dropbox, there exists a SharePoint folder that looks something like this: SharePoint ----Team --------Restricted Access Folders ----Organization --------Open Access Folders The Dropbox master account and the SharePoint master account are both set up on my file server. Unfortunately, Dropbox doesn't seem to allow syncing of folders anywhere above the \Dropbox\ part of the file system's hierarchy - or all I would have to do is find where the Sharepoint repository is maintained locally, and I'd be golden. So it seems I have to do some sort of 2-way synchronization between the Dropbox folder on the file server and the SharePoint folder on the file server. I messed around with Microsoft SyncToy, but it seems to be lacking in the area of real-time updating - and as much as I love rsync, I've had nothing but bad luck with it on Windows, and again, it has to be kicked off manually or through Task Scheduler - and I just have a feeling if I go down that route, it's only a matter of time before I get conflicts all over the place in either Dropbox, SharePoint, or both. I really want something that's going to watch both folders, and when one item changes, the other automatically updates in "real-time". It's quite possible I'm going down the entirely wrong route, which is why I'm asking the question. For simplicity's sake, I'll restate the goal: To be able to update Dropbox and have it viewable on the SharePoint site, or to update the SharePoint site and have it viewable in Dropbox. And since I'm a SharePoint noob, I'll also need help hiding the "Team" subfolder from everyone not in a specific group in AD.

  • Msys cd .. command takes me to home directory instead of parent

    - by Adrian
    I'm using Msys on Windows 7 with what I believe to be a Bash shell. I want to navigate the following directory structure: Drive (M:) +--- Coding +--- CPP +--- projects +--- other_folder_1 +--- other_folder_2 My fstab file contains the following line: M:/Coding/CPP/projects/ /home/Adrian/ ... which makes the projects folder my starting directory when opening the shell. Unfortunately when I try to cd .. out of projects, I end up in /home instead of CPP. I imagine this might be related to what I did in the fstab file. Is there any way for me to retain the projects folder as my starting directory while being able to cd into its parent directories?

  • Turning down the sound on a switched off user

    - by soandos
    If one switches users (i.e. user one switches off, and then another users logs in) and there is sound playing on the first user, that sound will continue to play for the second user. If the second user has admin rights, they can guess what program is causing the sound and then kill it, but that is very clumsy, and far more than what "needs" to be done. When I open the mixer, it just shows that sound is playing. How can I stop it?

  • Vanilla TeX Live 2009 on Ubuntu

    - by reprogrammer
    I installed TeX Live 2009 by following the instructions at http://www.tug.org/texlive/quickinstall. Then, to make my local TeX Live installation work with the Ubuntu package management system, I followed the instructions on http://www.tug.org/texlive/debian.html. That is, I performed the following steps. $ sudo aptitude install equivs $ mkdir /tmp/tl-equivs && cd /tmp/tl-equivs $ equivs-control texlive-local # I replaced the contents of texlive-local by http://www.tug.org/texlive/debian-control-ex.txt $ equivs-build texlive-local $ sudo dpkg -i texlive-local_2009-1~1_all.deb However, when I go about installing kile through the Ubuntu package management system, it requires me to install a lot of dependencies that are already provided by my texlive-local package. Does any one have a suggestion to fix this problem?

  • How to run MS C++ 6.0 on Windows 7

    - by hotei
    I have MS Windows C++ version 6.0 on XP. I'd like to move it to a Windows 7 platform but when I try to install it there I get some garbage about it not being compatible, proceed at your own risk etc. When I proceed, it (not surprisingly) doesn't work. Is there a way to convince these Microsoft tools to play nice with each other? I have Win7 home edition, but I would be willing to upgrade to Win7 Pro IF I knew it would work under the "XP emulation" mode. Failing both those options, what is the least expensive "upgrade" path for C++? I don't need a bunch of other junk, just the C++ compiler. The goal is to retire my XP system since currently the only reason I keep it is to compile C++ programs that eventually are run under Win7. Thanks, Hotei

  • KVM machine does not start ssh, network is started, used to work

    - by lleto
    have been searching an pulling my hear out for the last 6 hours. I have a virtual machine that has been running fine for the last six months. I was happy ssh'ing into it and it was running a database and some small apps. Tonight ssh stopped working, so I decided to reboot the machine. I now have the following situation: virsh list --all states machine as running I can ping the machine and get a reply When I ssh to the machine I see "ssh: connect to host [myserver] port 22: Connection refused" nmap does not show port 22 as open I have tried to: - reboot the machine once more (no luck) - mount the filesystem and check /etc/ssh/sshd.conf (has not changed since working situation) - install virsh console, however this does not seem to work When I mount the fs directly using losetup the strange thing is that file dates seem to be frozen in /var/log/ around the time of the crash. If I look in /var/run/ I can see an sshd.pid, but the time is 6 hours ago (and numerous reboots). My virsh xml looks like this: <domain type='kvm' id='21'> <name>myserver</name> <uuid>09678c8d-a99b-1d18-a7af-88d027cc8f93</uuid> <memory>1048576</memory> <currentMemory>1048576</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc-1.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/disk01/myserver'/> <target dev='hda' bus='ide'/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> <controller type='ide' index='0'> <alias name='ide0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:e3:13:86'/> <source bridge='br0'/> <target dev='vnet0'/> <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/1'/> <target port='0'/> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/1'> <source path='/dev/pts/1'/> <target type='serial' port='0'/> <alias name='serial0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1'> <listen type='address' address='127.0.0.1'/> </graphics> <video> <model type='cirrus' vram='9216' heads='1'/> <alias name='video0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </memballoon> </devices> <seclabel type='dynamic' model='apparmor' relabel='yes'> <label>libvirt-09678c8d-a99b-1d18-a7af-88d027cc8f93</label> <imagelabel>libvirt-09678c8d-a99b-1d18-a7af-88d027cc8f93</imagelabel> </seclabel> </domain> I'm sort of lost as to where I can look to get the machine up and running again.

  • How can I have Windows 8 go to the desktop by default?

    - by Schnapple
    I've played around a smidge with the Windows 8 Consumer Preview in a VirtualBox VM and I think the improvements under the hood may be worth tolerating the Metro UI crap. I don't like that the entire screen changes to something I don't care about when I hit the Windows key and start typing but I can deal with it. The one thing I cannot stand, though, is that it starts in the Metro interface by default. I have to hit the "Desktop" tile to get to a normal interface, and while I can hit "escape" to go back to the desktop and dismiss Metro, it doesn't work when you first log in. When you first log in, you have to hit that "Desktop" tile. I know that the Enterprise versions of Windows 8 will go to the desktop by default. I don't know but I would assume that there's probably some registry key that would handle this. Has anyone figured that out yet?

  • Configure Thunderbird to never send (or even try to send) HTML emails

    - by Brent.Longborough
    Where can I set it to tell Thunderbird to always send as plain-text emails and never as HTML formatted messages? I hate HTML-based email, and always do everything possible to send my emails as plain text. Thunderbird is always pestering me with questions like "This recipient cannot receive HTML..." or "In order to sign this email, it needs to be converted to plain text..." Is there a way I can simply say to Thunderbird "Look, old chap, it's all plain text, so don't bother me any more, ever, again"?

  • Standalone firewall + antivirus or combined security tools?

    - by pukipuki
    For years I'm using some antivirus software and different firewall. Now every antiviruses have got some firewall features and there are complete "internet security" complexes... and every firewall get some antivirus functionality and there are "internet security" versions. Firstly, it is hard and sometimes impossible to install and use standalone AV and FW. Sometimes I can't avoid them (i can't install KAV2010 without removing Outpost firewall etc). Secondly, complex solutions have some disbalance. Farewall from famous antivirus-brand is so user-friendly that is not suitable for me (lack of details in Norton Internet Security for example) and antiviruses from famous firewall-brands are still weak, it is proved by tests. What is today best-practices in case of functionality and security?) Some internet-security complex or two standalone applications from different vendors?
