  • How to crop a face in Photoshop

    - by oo
    I want to be able to crop a face out of a picture in Photoshop. The lasso tool seems to be difficult to use. I remember there was another tool that allowed you to put different lines together one by one and then complete a circle but I don't remember the tool. How can I do it?

  • Hard drive not correctly recognized on a new Windows 7 installation, but works correctly on Windows XP

    - by david
    I'm having problems configuring a hard disk in a brand new, clean Windows 7 installation. System specs: Hard disk: WD VelociRaptor WD6000HLHX (600 GB, 10000 RPM) Motherboard: Gigabyte Z77X-UD3H BIOS SATA mode set to AHCI (not RAID), with disk connected to SATA0 (6 Gb/s port). Windows 7 Enterprise SP1 64-bit The disk is recognized by the BIOS and is correctly identified, with the name and size correctly reported. Windows recognizes the disk itself and reports the device is functioning correctly, but it doesn't appear in Explorer. Disk Management shows the drive, but incorrectly states that it is uninitialized and has no partitions. If I try to initialize the drive, I get an error saying that "the system cannot find the file specified" (what file?). Before connecting the drive to the new machine, I partitioned and formatted it under Windows XP SP2, creating 2 partitions (MBR, not GPT) and copying over a boatload of data. However, none of this data appears under Windows 7. If I put the disk back into the Windows XP machine, I can access the disk and all of its data. Is it possible to get Windows 7 to correctly recognize the disk without having to erase it and start over? If so, how do I do so? I checked this question, which seems to cover the same issue, but it didn't help.

  • Concerns with compressing sensitive data in OSX

    - by Derek Adair
    Hi, I have some really sensitive data that I am trying to compress and back up so I can reformat. It's absolutely imperative that nothing happens to these files. I'm a developer so I have very little room for error... plus I'd really hate it if any of my .mp3's got corrupted! File Formats Include... .mp3 .php .js .ai - .psd - .flv (and many more) Is the mac OSX file compression safe enough? Or should I look elsewhere? Is there a more efficient/secure file-format other than .zip (i'm assuming so...)

  • How to install clonezilla on Ubuntu 9.10?

    - by Fantomas
    I installed latest Ubuntu on a flash drive. Was ready to install clonezilla with apt-get install clonezilla but that's not the way to do it? I prefer a physical install to a live one because I then have a chance to load specialized ntfs drivers for instance, should there be a need. How can I do this? Thank you!

  • How do I make vim's autoindent not drop trailing spaces?

    - by Joey Adams
    In some text editors (e.g. Kate, gedit), when auto indent is enabled, pressing return twice will leave a trailing whitespace (which I want): if (code) { .... ....| } While others cater to the coding standard where trailing spaces (even in blank lines) aren't allowed: if (code) { ....| } What annoys me about this is that if I arrow up after auto-indenting, the auto-indent is lost: if (code) { | .... } If I run vim and :set autoindent , I get the latter behavior. My question is, how do I set vim to keep the trailing spaces rather than automatically removing them if they go unused?

  • How harmful is a hard disk spin cycle?

    - by Gilles
    It is conventional wisdom¹ that each time you spin a hard disk down and back up, you shave some time off its life expectancy. The topic has been discussed before: Is turning off hard disks harmful? What's the effect of standby (spindown) mode on modern hard drives? Common explanations for why spindowns and spinups are harmful are that they induce more stress on the mechanical parts than ordinary running, and that they cause heat variations that are harmful to the device mechanics. Is there any data showing quantitatively how bad a spin cycle is? That is, how much life expectancy does a spin cycle cost? Or, more practically, if I know that I'm not going to need a disk for X seconds, how large should X be to warrant spinning down? ¹ But conventional wisdom has been wrong before; for example, it is commonly held that hard disks should be kept as cool as possible, but the one published study on the topic shows that cooler drives actually fail more. This study is no help here since all the disks surveyed were powered on 24/7.

  • Drobo FS vs Lime Technology unRAID vs FreeNAS

    - by elluca
    I already decided to by a drobo fs until I just found these two tests: http://www.digitalversus.com/data-robotics-drobo-fs-p889_9543_487.html http://www.digitalversus.com/lime-technology-unraid-p889_8992_473.html The two cons agains drobo for me: loudness price What disadvantages has the unraid stuff against the drobo fs? Has it also got that ease of use like swapping drives on the go, simply extend capacity by plugging in new drives, notify me of drive errors, disk failure protection, dynamic space of "partitions", better/worse effective capacity, etc. Which is more secure? Am I able to simply replace a bad drive with a new one on unraid? What happens if my pc fails? Lets say the cpu overheats. Since I have a complete pc which is going to be replaced, I only have to pay the software to use unraid. I am going to use my nas for: music library (how well does it integrate with iTunes? ) picture library movie library development (i need to be able to be to use time machine) I am going to use this nas with a MacBook pro. My current disks: 2x 500Gb 1x 1.5Tb 1x 2Tb On a drobo fs I would have 2.26 Tb of space. What would it be on unraid? Is FreeNAS also an alternative?

  • How do I enable greedy MigrationHeuristic in Karmic?

    - by Matthew
    My laptop performs very poorly for 2d graphics. For example, Docky's zoom effect and compiz effects are very choppy. In Jaunty, I was able to fix this by adding the following line under the "Device" section in my xorg.conf: Option "MigrationHeuristic" "greedy" In Karmic, there is no xorg.conf by default, so I copied my old one (from Jaunty). However, everything is still slow. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Option "MigrationHeuristic" "greedy" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection From googling about, it sounds like "MigrationHeuristic" is only an option for the "EXA" mode, while Karmic has switched the intel driver to "UXA". So I tried adding this line under the "Device" section: Option "AccelMethod" "exa" But this didn't help.

  • Mac OSX: which folders should ClamXav Sentry watch?

    - by trolle3000
    I'm using ClamXav on my mac. I've read this, and I am aware of the whole macs-need-no-AV-but-they-do-anyway discussion. I guess that's why I would feel like a real ass if I somehow managed to compromise my system! So ClamXav has been downloaded and ClamXav Sentry set up to start on log-in, but it doesn't really do anything before you tell it to. Specifically, you have to tell it which folders to watch for virusses/vira so I'm wondering, where are good places to look? Currently it's been set up to look the following places: In the home folder: ~/Downloads ~/Library/Caches ~/Library/Contextual Menu Items ~/Library/Cookies ~/Library/Internet Plug-Ins ~/Library/LaunchAgents In my system folder: /Library/Application Support /Library/Caches /Library/Contextual Menu Items /Library/Cookies /Library/Internet Plug-Ins /Library/LaunchAgents /Library/LaunchDaemons /Library/Startupitems Basically, this is 100% conjecture. All (most of) the folders have something to do with internet and things that start up automatically, so I'm guessing that's where vira go. But still, the qustion: Which folders should ClamXav Sentry watch, if any? FYI, I'm not using any mail app's, but please include that in your answer for anyone who might be interested. Cheers!

  • How to create custom Live CD with upgraded linux-image kernel?

    - by ???
    I'm following this tutorial to customize a Live CD, http://www.debuntu.org/how-to-customize-your-ubuntu-live-cd However, it's failed to upgrade linux-image, I guess it's just can't update-grub. Any idea? EDIT I copied the custom/ directory into an ext4 image, now the linux-image-2.6.35-24 package is successfully upgrade. But as shown in the original CDROM, the vmlinuz-* and initrd.img-* file is moved out to /casper/vmlinuz and casper/initrd.lz. Well, I can move vmlinuz-2.6.34-24-generic to /casper/vmlinuz, but how to compress file initrd.img-2.6.35-24-generic in .lz format? (It looks like lzip, but it's not: ) # cd original-maverick/casper # lzip -d initrd.lz initrd.lz: bad magic number (file not in lzip format).

  • how to properly set environment variables

    - by avorum
    I've recently started using Windows (having used Ubuntu up until now) and I find myself unable to properly set environment variables. Whenever I set them they don't seem to work. I've been going to Start-Edit Environment Variables for your Account and editing the PATH value in the upper half of the GUI. Here's what I've got so far. ;C:\Chocolatey\bin;C:\tools\mysql\current\bin;C:\Program Files (x86)\Git\bin;C:\Program Files\MySQL\MySQL Server 5.6\bin\;C:\Python33\Scripts; These are each the parent directories of the executables I'd like to be able to run by name from CMD, but mysql, git, and pip aren't being recognized. Am I doing something wrong syntactically or at a general understanding level? I'd like to be able to run these commands without having to specify the full path to the executables every time. EDIT: The full PATH extracted from CMD PATH=C:\Python33\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\Java\jre7\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft SDKs\TypeScript\;C:\Program Files (x86)\MySQL\MySQL Utilities 1.3.4\; ;C:\Chocolatey\bin;C:\tools\mysql\current\bin I'm being forced to use Windows by my work environment, I don't enjoy the state of affairs.

  • Extending home network using multiple access point originating from another access point

    - by cyberjar09
    I have a home network with the current setup (RJ45 running from main router to access point) : +-------------+ +--------------+ | 192.168.2.1 | |192.168.2.2 | | router +--------------->access point 1| +-----^-------+ +--------------+ | | +-----+--------+ | 192.168.1.1 | | modem | +-----^--------+ | | | | +--+--+ | ISP | +-----+ However I would like to extend the network to two more floors in the house via the existing Access Point (router is too far and not reachable using a network cable, hence I need to extend using current access point). Please see diagram below : +-------------+ +--------------+ +----------------+ | 192.168.2.1 | |192.168.2.2 | | 192.168.2.3 | | router +--------------->access point 1+----------> access point 2 | +-----^-------+ +--------+-----+ +----------------+ | | | | +-----+--------+ | | 192.168.1.1 | | | modem | | +-----^--------+ | +----------------+ | +----------------> 192.168.2.4 | | | access point 3 | | +----------------+ | +--+--+ | ISP | +-----+ Q1 : is this setup possible? Q2 : if possible, will I have to do anything different from what I did to setup access point 1? edit 1 : I am trying to study the dd-wrt documentation to see which would be the correct mode of operation for me Linking Routers but Im confused because I dont see any info on how to use an existing Access point to extend the signal of the SSID. If anyone could point me to the correct wiki for how I should setup AP2 and AP3 based on AP1, it would be very helpful. For AP1, I did the following Use static IP and setup same SSID as primary wireless router use same security as primary wireless router make AP1 point to 192.168.2.1 (primary router) for DHCP Thanks in advance.

  • How can I trap errors for an application that is tightly coupled with IIS?

    - by PeanutsMonkey
    We have an unsupported application that relies on IIS however intermittently brings out the website it is integrated with. I have looked at the logs and there is nothing in the logs to indicate what the issue could be as the logs only have GET verbs. I have also looked at the event viewer and there are no error logged in there either. The application runs off a Windows 2008 server. Is there a freely available application we can have running in the background that will listen to or is aware of the application running and traps the error when it crashes? The unsupported application is a bespoke implementation for which we don't have code for and the developer is no longer contactable.

  • "sed" regex help: Replacing characters

    - by powerbar
    I want to change characters in a XML file by using sed. The input looks like this: <!-- Input --> <root> <tree foo="abcd" bar="abccdcd" /> <dontTouch foo="asd" bar="abc" /> </root> Now I want to change all c to X in the bar tag of the tree element. <!-- Output --> <root> <tree foo="abcd" bar="abXXdXd" /> <dontTouch foo="asd" bar="abc" /> </root> How is the correct sed command? Please consider, there can be more than one occurence of c (next to each other or not) in one tag... I tried this myself, but it won't change multiple c, and it does append a X :( sed -i 's/\(<tree.*bar=\".*\)c\(.*\"\/>\)/\1X\2/g' Input.xml

  • Can you tell by the network traffic whether a video was watched or downloaded from YouTube?

    - by humanityANDpeace
    My question is about quite popular YouTube downloaders like youtube-dl (a command line program) or VideoDownloadHelper (a Firefox-browser extension). Comparing two cases: Watching a video on YouTube Download the video using a downloader (to be specific let's assume youtube-dl) Is it possible to tell – for instance by inspecting the network traffic – that the video was downloaded and not "only watched" on YouTube? Maybe one could compare network traffic using programmes like Wireshark? I cannot do that myself, but maybe this will help somebody to answer the question.

  • Conditionally format row based on cell value in Excel 2011 Mac

    - by kojiro
    I'm using Excel Mac 2011. I have read some of the other answers, but this question is different because I want to apply conditional formatting to an entire row when its cell in column B contains the value 'Y'. Simple conditional formatting just formats that one cell. Whenever the field at column B for any given row contains the value 'Y', I'd like to format that row. Using Mac Excel's so-called "classic" conditional formatting, I have this: I would really like to apply that to every row, but it just paints the entire sheet red (because $B$3 contains "Y"). I can't seem to figure out how to get the reference to whatever is in field B for this row in the rule.

  • Force Colloquy not to use built-in Growl notifications

    - by thepurplepixel
    Whenever Colloquy needs to pop up a notification (for example, when you are PM'd), it uses its built-in Growl notifications, which really annoy me because they stay on the screen until they are clicked (at least NOTICE's do anyways). I'd like to make Colloquy use the Growl that I have installed on my Mac, not its built-in Growl notifications. That way, I could change its preferences from the Growl .prefpane and it would match the look of all my other notifications. I seem to remember this being possible (maybe in a bug report or something), but I can't remember how. Thanks!
