  • Is it safe to buy a replacement laptop battery that has slightly different voltage than the original?

    - by Hugoagogo
    I'm looking for a new battery for my Acer Aspire 4741g laptop. I am trying to get a higher capacity battery. Many sites (like this one and this one) list batteries that are interchangeable with the battery that came with the laptop (AS10D41). These batteries have higher capacity, but also marginally lower voltage (11.1V vs. 11.8V). Is this a problem? Does it mean that the battery is actually incompatible? The replacement battery I am looking at is AS10G3E, and is listed in many places as being compatible with the AS10D41, but nobody makes any mention of the differing voltages. I am trying to find out what kind of problems a lower voltage battery can cause. I know P=IV; with reduced voltage, will the machine draw more current, possibly damaging components? I'm just speculating, but I'm worried about the chance that using a battery at a lower voltage will damage my laptop.

  • FreeBSD after motherboard replacement; should I have any concerns?

    - by cc
    So after three years my motherboard (Asus M2N-0MX) has died off. As I go shopping for i's replacement tomorrow I have a concern about the data that I currently have on the drives wtihin. I'm currently running BSD 6.2, and am wondering if there would be any concern with installing a new OS on that system, would it be better to jsut install the latest BSD version, and are their any pitfalls that I should watch for to make sure I don't end up losing 750gb's of data. The setup consists of the following(to the best of my knowledge): Pioneer DVD drive 3ware RAID card four 250gb SATA drives in RAID 5 config thanks to anyone that can offer some advice, or just to confirm if I am over thinking things.

  • Is there a free, lightweight iTunes replacement for Windows?

    - by elsni
    Related: Is there an alternative to iTunes? (for Windows or Mac) thats free? I'm looking for a free, lightweight iTunes replacement for my Windows XP Netbook. iTunes itself is slow and bloated. The software should be able to read the iTunes library, espeacially the ratings of the songs and the intelligent playlists. I don't need the sync to an iPod because I don't own one, I used iTunes only as a jukebox. I also don't need the store, the podcasts and all the other things iTunes provides. Does someone know a good alternative?

  • Is there an RSM replacement in Windows 7? (to eject USB and Firewire devices from command line)

    - by Jay
    I know Windows XP and previous had an rsm.exe file in the <root>\windows\system32 folder that could be used to manage media. I used this command in batch files and from the command line to eject external disks (iPod, CF cardreader, etc.). This utility appears not to be included in Windows 7, and I wonder if there is some replacement utility that will allow the same thing. I've been unable to find any such thing. I'm aware of the 3rd party utilities; this question is only about what is included with Windows 7.

  • Can I use Cygwin as a replacement for Ubuntu, for bash script testing?

    - by Jeroen De Meerleer
    Next wednesday i'm having an exam on Operating Systems. In this exam there will also be a part bash-scripting. The teacher itself will test the scripts in a Virtual Machine running Ubuntu. Myself, however, I'm having serious troubles with running the latest Ubuntu (14.04 LTS) on a Virtual Machine (there are troubles with gnome running very slow). So I'm thinking about using Cygwin, which is doing the job great for another course. The teacher already confirmed I can use that, but I'm thinking he doesn't know it at all. I've already tested the scripts we made in class and they're all running without errors. But I'm quite sure there are some things I have to mind on. My question: would you use Cygwin as a replacement for the Ubuntu VM? Or should I stick it with the VM (maybe by using a different config/platform).

  • firefox scales images poorly

    - by Jabba
    Hi, I'm using Ubuntu Linux and when I zoom in on a page with "CTRL - +" the images become ugly, i.e. Firefox doesn't scale them correctly. Using Chromium-browser I don't have this issue. I have this problem on several machines with various versions of Firefox (3.5-3.6). Here is an example: http://xs.to/image-2AA4_4BDA24DE.jpg . Any idea how to change the scaling behaviour of Firefox? Thanks, Jabba

Thanks in advance, Samuel

    I'm using some Images in my WPF applcation.

  • Java: Send BufferedImage through Socket with a low bitdepth

    - by Martijn Courteaux
    Hi, The title says enough I think. I have a full quality BufferedImage and I want to send it through an OutputStream with a low bitdepth. I don't want an algorithm to change pixel by pixel the quality, so it is still a full-quality. So, the goal is to write the image (with the full resolution) through the OuputStream with a very small size. Thanks, Martijn

  • How does an unsharp mask work?

    - by Bob Aman
    I've been playing around with image processing lately, and I'd like to know how the unsharp mask algorithm works. I'm looking at the source code for Gimp and it's implementation, but so far I'm still in the dark about how it actually works. I need to implement it for a project I'm working on, but I'd like to actually understand the algorithm I'm using.

  • smallest filesize for transparent gif

    - by zaf
    I'm looking for the smallest (in terms of filesize) transparent 1 pixel image. Currently I have a gif of 49 bytes which seems to be the most popular. But I remember many years ago having one which was less than 40 bytes. Could have been 32 bytes. Can anyone do better? Graphics format is no concern as long as modern web browsers can display it and respect the transparency.
