• Durable laptop power adapter?

  - by snitzr

  I'm on my third power adapter for my HP Pavilion dv4-1435dx in less than one year. I'm not abusing them. I used Mac laptops for 10 years (before needing to switch to a PC) without a problem. I tried a Targus universal power adapter, but it wouldn't charge my PC, it worked fine on another laptop http://www.targus.com/us/product_details.aspx?sku=APA6911US Any suggestion for a more durable and reliable power adapter?

• Journaled filesystems and power failure

  - by Yoga

  I heard that even a journaled filesystems such as EXT3/EXT4 might corrupted during power failure, e.g. from wikipedia [1]: In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted. Can anyone provide more detail by giving examples such that when corruption can occur corruption is avoided by journaled filesystems [1] http://en.wikipedia.org/wiki/Journaling_file_system

• How to server a small image at a larger size

  - by DennyHalim.com

  We all know about hotlinking images and how to ban bad referrers, but I feel the need to take it further then that. I want to replace the hotlinked images with one huge image that's several megabytes in size. I have found a good image that's less then 100k and replaced all bad hotlinkers with it. How can I convert this image to become larger?

• Give me a sweet and simple XML viewer/editor for Windows

  - by Will

  I'm not talking about a full-weight and size editor. I'm talking about something better than Notepad and faster to load and less bloated than Visual Studio. Minimum requirements would be syntax highlighting.

• How print multiple independent pages in one print job?

  - by C.W.Holeman II

  How can I combine multiple single page prints into a single print job? For example, using Firefox on Linux one can print a web page such that each sheet of paper has four pages printed upon it. I would like to combine several separate web pages so that for example, web-page-a, web-page-b and web-page-c (each less than one print page long) are printed on a single sheet of paper. I would like to do this without having to use some for of image editor to combine them.

• Narrow size column in Vista Explorer to say 60 pixels

  - by jonrichco.yahoo.com.au

  In XP Explorer you could drag column widths to any size you wanted. However, annoyingly Vista does not allow you to set them to less than 80 pixels, losing valuable screen real estate. I have asked this question on a few tech sites - this is the last time I will ask it. Hope someone can help. Dell Inspiron 1501, Vista Business SP2

• Good maintained privacy Add-On/settings set that takes usability into account?

  - by Foo Bar

  For some weeks I've been trying to find a good set of Firefox Addons that give me a good portion of privacy/security without losing to much of usability. But I can't seem to find a nice combination of add-ons/settings that I'm happy with. Here's what I tried, together with the pros and cons that I discovered: HTTPS Everywhere: Has only pro's: just install and be happy (no interaction needed), loads known pages SLL-encrypted, is updated fairly often NoScript - Fine, but needs a lot of fine-tuning, often maintained, mainly blocks all non-HTML/CSS Content, but the author sometimes seems to do "untrustworthy" decission RequestPolicy - seems dead (last activity 6 months ago, has some annoying bugs, official support mail address is dead), but the purpose of this is really great: gives you full control over cross-site requests: blocks by default, let's you add sites to a whitelist, once this is done it works interaction-less in the background AdBlock Edge: blocks specific cross-site requests from a pre-defined whitelist (can never be fully sure, need to trust others) Disconnect: like AdBlock Edge, just looking different, has no interaction possibilities (can never be fully sure, need to trust others, can not interact even if I wanted to) Firefox own Cookie Managment (block by default, whitelist specific sites), after building own whitelist it does it's work in the background and I have full control All These addons together basically block everything unsecure. But there are a lot of redundancies: NoScript has a mixed-content blocker, but FF has it's own for a while now. Also the Cookie blocker from NoScript is reduntant to my FF-Cookie setting. NoScript also has an XSS-blocker, which is redundant to RequestPolicy. Disconnect and AdBlock are extremly redundant, but not fully. And there are some bugs (especially RequestPolicy). And RequestPolicy seems to be dead. All in all, this list is great but has these heavy drawbacks. My favourite set would be "NoScript Light" (only script blocking, without all the additonal redundant-to-other-addons hick-hack it does) + HTTPS Everywhere + RequestPolicy-clone (maintained, less buggy), because RequestPolicy makes all other "site-blockers" obsolete (because it blocks everything by default and let's me create a whitelist). But since RequestPolicy is buggy and seems to be dead I have to fallback to AdBlock Edge and Disconnect, which don't block all and and need more maintaining (whitelist updates, trust-check). Are there addons that fulfill my wishes?

• Xen guest miration to host with missing features

  - by deploymonkey

  If I want to move a xen guet (domU) from one host (dom0) to another host on another hardware platform which misses some capabilities, say virtualisation features, especially directio or likewise, will my image be able to run despite missing capabilities of the new host? This is important because I need to know if I can prepare XEN images on my workstation with full virtualisation features and deploy same images on less capable Servers later on. Thanks for the help and input

• Why should I choose either PCL or PS when both are supported

  - by Goyuix

  Obviously the answer depends to some degree on the various versions supported, but in general terms - is there any reason I should pick one over the other? PCL for art and PS for text? Does one typically require less RAM on the printer? Speed differences? For home use it doesn't matter and only professional print people will notice and care?

• OpenOffice 3 takes forever to open

  - by Joey Adams

  I'm on Fedora 14, and OpenOffice 3.3.0 takes a long time to open (about 30 seconds, sometimes less). It isn't a CPU or disk performance issue, it's just simply a very long delay before the program opens. It appears to be a frivolous network connection timing out. According to Wireshark, it tries to look up: dulcimer.(none) which fails, after which it tries to look up: dulcimer.(none).mylitestream.com (dulcimer is my hostname, and LiteStream is my ISP) Is there a way to work around this bug in OpenOffice?

• Upgrade processes between FreeBSD/Ubuntu

  - by bianster

  Are there significant differences between FreeBSD and Ubuntu Linux when it comes to upgrading? FreeBSD appears to offers a more reliable path for upgrades with "freebsd-update" though I think "apt-get update --system" is the equivalent for Ubuntu. I'll like to know which one is less likely to produce SNAFUs when undertaking minor/major updates.

• How can I unbind a UDP port that has no entry in lsof?

  - by Chocohound

  On my Mac, I have a UDP port that is "already in use", but doesn't have an associated process: sudo netstat -na | grep "udp.*\.500\>" shows udp4 0 0 192.168.50.181.500 *.* udp4 0 0 192.168.29.166.500 *.* sudo lsof doesn't show a process on port 500 (ie sudo lsof -i:500 -P reports nothing). Note I'm using 'sudo' on both commands so it should show all processes. (rebooting works, but looking for something less disruptive) How can I unbind port 500 so I can use it again?

• Disable scroll acceleration (windows/lenovo)

  - by dhardy

  Exactly the opposite of http://superuser.com/questions/101482/global-scroll-acceleration-in-windows, is there a way to disable scroll-accelartion on windows (touchpad -- maybe from lenovo drivers). It's heck of annoying -- using no accelartion but high sensitivity like on linux is so much more precise. ( With this silly acceleration, I either have incredibly slow scrolling, or scrolling so fast it skips whole chunks of text at once. Speed control but not acceleration control. Could say the same for mouse cursor, though that's less annoying. )

• iMac memory limit

  - by Mike

  I have an iMac that was from the first generation of aluminum iMacs. The reported model is "iMac 7,1". This iMac's manual says I can put 2 2GB modules, but when this manual was made we don't have modules with more than 2GB and also we had Leopard then, that I suppose can handle less memory than Snow leopard. Today we have 4GB modules, so can I put two 4GB modules and make it 8GB? thanks.

• System beeps continuously if both RAM sticks inserted

  - by JGB146

  I have two sticks of OCZ 2GB PC2 9600 RAM. When I attempt to boot with both sticks inserted, I am met with a continuous string of system beeps (and no bootup). The system boots fine when only one stick is inserted, but obviously that leaves me with less RAM than I'd like to have. What could the problem be? System specs are: Gigabyte GA-EP45-UD3L Intel Core 2 Quad Q9400 Sticks of OCZ 2GB PC2 9600 RAM Zotac GeForce GTS 250 1GB 2x Seagate 500GB SATA HDs

• On a linux server how do you use multiple terminals over a single ssh connection?

  - by epochwolf

  I often find myself opening several ssh connections in order to view several log files at a time with tail -f. This isn't a problem when I'm at home because I use public key encryption for password-less login. However, I will often use computer at my university to do this so I don't have the option of using my private key. It gets annoying to enter my password 4 or 5 times to get several terminal windows. How can I get multiple terminals over a single connection?

• the effect of large number of files on disk space in unix filesystems

  - by user46976

  If I have a text file in Unix that contains N-many independent entries (e.g. records about employees, where each employee has a separate record), is it expected that this file will take up less space than if I split the file into N files, each containing the entry for one employee? in other words, can one save significant space on unix file systems by concatenating many files together, or is the difference negligible? thanks.

• Freeware (preferably open-source) tool for creating multi-file spanning archives as a self merging SFX

  - by Lockszmith

  I have a large file I want to transfer using either Internet storage hosting, DVD-Rs or USB storage, which sometimes is limited to FAT file-systems (for example: mobile phones) What I'm basically looking for is a tool that create multiple files/volumes (less than 2GB each - FAT's file size limit) which are packed with a self-extracting executable. Currently the only tool I found doing this is WinRAR, but that's shareware, and not free. Is there any Free, preferably Open-Source tool that does that? Thank in advance

• Mysql replication, Slow resyncing of slave after an error

  - by James Hackett

  I have a slave that got an error about a months or so ago and got way behind the master. I fixed the error and now playing catchup with the master but its going very slowly. Its going at 1.3x real time. I was using less that 10% of the db resources when these writes were first happening so the speed of the server shouldn't be an issue. Is there any settings I can switch to help the slave catch up with the master?

• Best software to convert video to a different aspect ratio for various screensizes

  - by facepalmd

  I sometimes get .mp4 and other video formats whose aspect ratio is clearly off What apps do you use to reconvert such videos to an aspect ratio better suited to to fit either a regular desktop or LCD screen size? Hopefully with little or no loss of audio/video quality Any instructions on best settings to use would be very welcome. I have so far mostly used vlc which came off with less-than-ideal results. Thanks for any help you can offer.

• Use an audio/video file from a Linux laptop via USB to be played by Magic Sing ET-23H

  - by AisIceEyes

  I am one of the technical directors of a regular karaoke contest event. For the karaoke contest itself, due to tight budget, we are using what one of the sponsors are providing - Magic Sing ET-23H . The video output of the Magic Sing ET-23H are broadcasted at two big screens that are being shown to the audience and event attendees. When a karaoke contestant provides his / her karaoke video, the video itself is in a readable USB flashdrive and is attached to the USB input of Magic Sing ET-23H. What really bugs me is that the interface of Magic Sing ET-23H are also being broadcasted at the big screen video feeds. The interface of choosing the video file is being seen in the Magic Sing ET-23H - also to the big video screens that are seen by the audience and event goers. I will post in the comments ( if my less than 10 reputation would allow me) the picture of Magic Sing ET-23KH USB input of the device. I always bring my laptop, Acer AS5742-7653, during the regular karaoke event. I'm using my laptop also for tallying of scores from the judges, and also playing audio files from contestants that did not provide a karaoke video. I personally am using different Linux distros, but I next to all the time use my Ubuntu Studio 12.04.3 64bit partition during the regular karaoke contest event. My question is this: Is there a way I can share a temporary video/audio file directly from the laptop I'm using, going to the Magic Sing ET-23H that can broadcast both the video/audio file? Just like how in Window's Avisynth AVS files, or VirtualDub's temporary avi file, or like using ffplay (of ffmpeg), etc. I have researched somewhat the matter and found links in SuperUser.com. Though I can only provide the links at the comments section of this post if my reputation of less than 10 would allow me. I have a hunch it is possible, but I have not fully understood the device being used at the event, Magic Sing ET-23H, if there are other ways for it to broadcast video and audio files besides its USB input. Any help to my current predicament is highly appreciated. Thank you. PS: Since I need at least 10 reputation to post more than 2 links and also post images, I will try to post the image & links at the comments (if my below 10 reputation would allow me).
