  • How do I calculate the cost of printing a given page?

    - by Alenanno
    I have seen questions like How much does a square inch of ink cost and How much more will a high-dpi image cost to print?, but mine isn't asking neither about a specific case, nor about how much something costs, as that would depend on the toner, for example. Rather, I was wondering how should I go about calculating the cost of printing a given page. Note that "given page" should be seen as a sort of x, i.e. the answer should be applicable in any case; I'd like this question to provide a good reference for those who want to calculate this cost. What should be taken into consideration? The cost of a single page (the paper only) is easily checkable, since you divide the cost of the whole package for the number of pages in the package itself. But how do I calculate the cost of the ink/toner? Which could translate to: how do I calculate the Ink Density1 for a given printer? I know it depends on quality of the printer itself, the type, the quality of the image being printed, the very nature of what I'm going to print, etc. But again, the focus of my question is not on the variables of this case, but rather the constants, hoping the math simile works for this case too. 1: Total amount of ink in one area of the page.

  • Mysterious OS X FileVault-related home directory

    - by Nick
    I recently enabled FileVault on Snow Leopard, and after doing so, found a directory /Users/<myusername>.4529809818604982560, containing the original (unencrypted) contents of my home directory, owned by root:wheel with permissions 700, side-by-side with my normal home directory. Does anyone know why this was created (maybe a temporary backup that didn't get erased), or whether deleting it will be harmful?

  • Cannot delete podcast from iPod Touch

    - by rybl
    I am having a problem with my iPod/iTunes where an episode of a single podcast cannot be deleted. The episode in question does not show up in iTunes or as being on the iPod when I drill down and look at the podcasts on the iPod in iTunes. It also does not play if I try to play it on the iPod; it just waits a second and skips to the next podcast. I have iTunes 9.2.0.61, my iPod has OS version 4 (although I was having this problem before I upgraded), and Windows 7 64bit. I would really prefer a solution that does not require me to completely wipe the iPod because I have a bunch of WiFi keys stored that I don't want to have to dig up again.

  • Can't find a Wordpress image/photo gallery plugin

    - by mgroves
    I've been looking at Wordpress plugins for photo galleries (so maybe this is for superuser.com), and I've been very frustrated so far. It seems like what I'd like to do would be a very common use case: Admin: Be able to upload multiple pictures (at a time) Admin: Be able to assign a "gallery" to those pictures as I upload them User: Be able to go to a page with a (paged) list of all galleries User: Be able to click on gallery and view the images (again, probably paged) in that gallery User: Be able to click on an image to get larger/largest sizes User: Be able to leave comments on individual pictures (this is a "nice to have") The images/galleries could be totally independent of posts/pages, but it would be nice to be able to embed those images/galleries into posts/pages when necessary. Is there anything out there like this that I'm missing? I've tried a handful of plugins and none of them seem to be for a use case anywhere close to what I'm looking for. One of the reasons I'm trying to use Wordpress is to reduce time spent coding everything I want.

  • What causes Windows Boot to stall?

    - by Nick Berardi
    For about 6 months now I have been having this weird problem where Windows 7 fails to fully boot correctly. What happens is this. Starting Windows shows up on the screen. Then 3 out of 4 times nothing else happens, no Windows Flag animation, just nothing occurs. After 3 or 4 restarts repeating steps 1-2 above, the Windows Flag animation finally shows up and everything works as expected. My question is what is causing this problem in steps 1 and 2? Because I have tried the following with no luck: Error checking and correcting of any disk errors Updating drivers Doing a clean install of Windows 7 My setup is as follows: Windows 7 64-bit Ultimate 8 GB RAM 128 GB Crucial SSD (firmware 0005) Dell Latitude E6410 Intel Wireless and Graphics Other than what I have tried above I am totally out of ideas and looking for some new ones to try.

  • Why is hibernation still used?

    - by Moses
    I've never quite understood the original purpose of the Hibernation power state in Windows. I understand how it works, what processes take place, and what happens when you boot back up from Hibernate, but I've never truly understood why it's used. With today's technology, most notably with SSDs, RAM and CPUs becoming faster and faster, a cold boot on a clean/efficient Windows installation can be pretty fast (for some people, mere seconds from pushing the power button). Standby is even faster, sometimes instantaneous. Even SATA drives from 5-6 years ago can accomplish these fast boot times. Hibernation seems pointless to me when modern technology is considered, but perhaps there are applications that I'm not considering. What was the original purpose behind hibernation, and why do people still use it? Edit: I rescind my comment about hibernation being obsolete, as it obviously has very practical applications to laptops and mobile PCs, considering the power restrictions. I was mostly referring to hibernation being used on a desktop.

  • Batch file to ZIP only files in directory or sub directory

    - by PaulJavier
    I wanted to know if possible how to create a command line to do the following - if a directory exist ZIP only the contents into a ZIP file. If a directory has sub-directories ZIP only the contents into another ZIP file. Example: C:\Directory\sample.txt ZIP only sample.txt C:\Directory\Directory1\sample1.txt ZIP only sample1.txt C:\Directory\Directory1\Directory2\sample2.txt ZIP only sample2.txt So it would have created 3 zip files in C:\Directory and sub-directories. I will not know the name of the sub-directories so can I also assign some sort of variable that says if there are directories or sub-directories in C:\Directory then start above ZIP(s)? Thank you, Paul

  • How to combine wildcards and spaces (quotes) in an Windows command?

    - by Jan Fabry
    I want to remove directories of the following format: C:\Program Files\FogBugz\Plugins\cache\[email protected]_NN NN is a number, so I want to use a wildcard (this is part of a post-build step in Visual Studio). The problem is that I need to combine quotes around the path name (for the space in Program Files) with a wildcard to match the end of the path. I already found out that rd is the remove command that accepts wildcards, but where do I put the quotes? I have tried no ending quote (works for dir), ...example.com*", ...example.com"*, ...example.com_??", ...cache\"[email protected]*, ...cache"\[email protected]*, but none of them work. (How many commands to remove a file/directory are there in Windows anyway? And why do they all differ in capabilities?)

  • MS-DOS 7.1, Active-Boot

    - by user3005255
    I created a MS-DOS 7.1 (Win 98) active-boot USB-flash stick and it functions properly. Nevertheless I still have some unsolved issues: I want to change my keyboard-layout to german but I don´t know where to start since I only have the "basic-DOS" with IO.sys, MSDOS.sys + command.com. I already created Autoexec.bat + config.sys but don´t know which files I need and which I have to change in order to get a german keyboard. Also I can´t really shutdown my DOS properly, what is the right way to do it in MS-DOS 7.1? Thanks very much in advance for your help!

  • Certificates required for WHQL-certified drivers

    - by Kasius
    The 64-bit Windows 7 image that we deploy to machines at our site does not contain all of the certificates included on a default Windows image. Automatic root certificate installation is also disabled per policy from higher in the organization. We have had a lot of trouble installing many WHQL-certified drivers from reputable companies (ex. HP, Lexmark, Dell, etc.), and I hypothesize that a required certificate is missing from one of the certificate stores on the machine. The error we typically get is: The driver cannot be installed because it is either not digitally signed or not signed in the appropriate manner. I know that it is signed. A .CAT file is included, and it has the following tree from top to bottom: Microsoft Root Authority (thumbprint a4 34 89 15 9a 52 0f 0d 93 d0 32 cc af 37 e7 fe 20 a8 b4 19) Microsoft Windows Hardware Compatibility PCA (thumbprint 93 b8 d8 82 0a 32 db 20 a5 ea b6 8d 86 ad 67 8e fa 14 ea 41) Microsoft Windows Hardware Compatibility Publisher (thumprint b0 50 45 45 42 4e be 2c 16 2f 62 5b bf 5a e6 9b 96 bf 0b 0b) What certificates are required to install WHQL-certified drivers? Is it possibly something other than certificates? Thanks! NOTE: I have posted this question on Technet as well, but honestly, I've never had a lot of luck posting questions on the Technet forums.

  • Tools to automate recording streaming radio

    - by Stan
    Are there any tools that can automate recording online streaming radio? I've been using Total Recorder which has the following useful features: Handy scheduler Supports creating recording templates, so I can customize some high/low quality recording Unfortunately it requires opening the streaming radio in a browser and can't have another sound source at the same time; it's recording what comes out from the speaker. What I am looking for is given an online radio URL, the tool should be able to record the audio stream, no matter if I am playing any other music or not. Does such a tool exist?

  • Can I connect a Playstation 3's HDMI output to my monitor's DVI-D input? [migrated]

    - by HankJDoomstorm
    I'm attempting to connect my Playstation 3 to my computer monitor. The monitor has a DVI-D (dual link) input, so before distinguishing between the different DVI varieties, I bought a DVI-I (dual link) to HDMI converter that won't fit into the port on the monitor (not only that, there isn't enough physical space in the back of the monitor to fit that much stuff before it hits the bottom of it). So I grabbed a DVI-D (single link) cable and got a female-to-female DVI-I coupler, and plugged the DVI-D cable into the monitor and the whole mess of converters. The end result was HDMI to DVI-D single link, but my monitor isn't receiving a signal on its digital channel. (For clarity's sake: DVI-D DL input on Monitor, DVI-D SL cable, DVI-I DL female-to-female coupler, DVI-I DL to HDMI converter, HDMI output on PS3) I don't know much about this stuff (obviously), but my educated guess is that the bandwidth of the PS3 is too high for the DVI-D Single Link cable, so nothing's getting through. Will replacing the single link cable with dual link resolve this? If not, is it possible at all? Oh, I should mention I'm aware I won't get audio through the monitor. I have an RCA to 3.5mm converter for that.

  • mplayer dumpstream sometimes fails

    - by User1
    I'm trying to rip the video at http://videolectures.net/ecml07%5Fgetoor%5Fisr/, so I can play it at a faster speed. I paste http://193.2.4.216/2007/pascal/ecml07%5Fwarsaw/getoor%5Flise/ecml07%5Fgetoor%5Fisr%5F01.wmv into a firefox browser in Windows and MediaPlayer plays the thing. However if I try mplayer -dumpstream, it gets stuck into an infinite loop trying to play the file. If I use wget to download the link, I get a small text file which basically points to the same URL. How can I get mplayer to download this stream?

  • Edubuntu video playback and apt-get

    - by asdasd
    They had installed some modified edubuntu's at school... So i have some questions about setting some things up: How we can play HD videos ? They are made for windows machines and are in .wmv format but we need to play them on our multimedia class but don't know how - which player, which codecs etc. How to edit properly the /etc/apt/sources file ? Anything we try to install via apt-get it just says that E:\ is not available. Please tell me which repositories to put in there so we could be able to install some tools. Where are usually viruses/trojans put in ubuntu ? I mean in which directories ? Because our computers are behaving really slow and we need to check for some malware manually - we are not even allowed to install any kind of AV software. So tell me the usual directories and places for hiding such files, how are they hiddem, how to recognize them etc. Any others nice tricks/tips that we need to know. Thank you very much in advance.

  • TextMate - completion using an external file or file contained in project?

    - by Neil Baldwin
    Does anyone know how to get TextMate to search an external file (or even the files contained in a TextMate "project") with which to perform word completion? I'm coding some stuff on the C64 (using TextMate to write the code) and I have an external file containing labels for all of the hardware registers/kernal routines e.g VIC2InteruptStatus = $D019 It would be really handy to be able to type, say, 'VIC2I' then press the key for word completion and have TextMate find matches in the external library file. Rather than how I'm having to do it at the moment by opening the library file and copy-paste the register names into my code.

  • Remove c:/windows/syswow64/msxml4.dll

    - by Rolf
    A program has installed c:/windows/syswow64/msxml4.dll on my hard drive. Sadly this is an old version (4.30.2100.0) with a security problem therefore I really wants to remove the file and the program that installed it. MSXML4 is not in the list of programs that I can uninstall under "Programs and features". Is there a way to find the program that installed it in windows 8.1? Hope some of you can help.

  • Saving a file in a CSV type in Excel always removes the BOM

    - by rickp
    I've been trying to find a reasonable solution/explanation (unsuccessfully) to find out why Excel defaults to removing the BOM when saving a file to the CSV type. Please forgive me if you find this a duplicate of this question. This handles reading CSV files with non-ASCII encoding, but it doesn't cover saving the file back out (which is where the biggest issue lies). Here is my current situation (which I'm going to gather is common among localized software dealing with Unicode characters and a CSV format): We export data to a CSV format using UTF-16LE, ensuring the BOM is set (0xFFFE). We validate after the file is generated with a Hex editor to ensure it was set correctly. Open the file in Excel (for this example we're exporting Japanese characters) and witness that Excel handles loading the file with the correct encoding. Attempts to save this file will prompt you with a warning message indicating that the file may contain features that may not be compatible with Unicode encoding, but asks if you'd like to save anyway. If you select the Save As dialog, it will immediately ask you to save the file as "Unicode Text" rather than CSV. If you select the "CSV" extension and save the file it removes the BOM (obviously along with all the Japanese characters). Why would this happen? Is there a solution to this problem, or is this a known 'bug'/limitation of Excel? Additionally (as a side issue) it appears that Excel, when loading UTF-16LE encoded CSV files, only uses TAB delimiters. Again, is this another known 'bug'/limitation of Excel?

  • Windows 7, going crazy with environment variables

    - by roymustang86
    So, I am trying to learn java. I installed the JDK and proceeded to write a few programs. Each time, I have to give the path to javac.exe to compile the .java file. SO, I decided to tweak the %PATH% variable. And no matter what I change it to, it doesn't work. when I do an echo %PATH%, I get 'Program' is not recognized as an internal or external command, operable program or batch file. This is my Path variable contents : C:\app\product\11.1.0\client_1\bin;%CommonProgramFiles%\Microsoft Shared\Windows Live;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;"C:\Program Files (x86)\Common Files\Roxio Shared\DLLShared\";"C:\Program Files\Broadcom\Broadcom 802.11";"C:\Program Files (x86)\Common Files\Roxio Shared\OEM\DLLShared\";"C:\Program Files (x86)\Common Files\Roxio Shared\OEM\DLLShared\";"C:\Program Files (x86)\Common Files\Roxio Shared\OEM\12.0\DLLShared\";"C:\Program Files (x86)\Roxio\OEM\AudioCore\";"C:\Program Files (x86)\Intel\Services\IPT\" How do I work around this? the double quotes were not there before, I added it thinking the space was the problem.

  • Do virtual machines perform better on the host HDD or USB drive?

    - by Jeremy Ricketts
    The question I'm asking is kind of general, and I'll give more specifics about my specific setup. Here's the main question though: Do virtual machines generally perform better on the host HDD or is it better to operate them from an external disk? My specific setup: A Macbook Pro with a nearly full internal SATA drive that spins at 7200. On this system I'm running large programs like Photoshop and some other RAM-intense applications. I've dedicated 2 of my 8 gigs of RAM to my VMware Fusion virtual machine, which runs Windows 7 and Visual Studio, sits on the same drive. When that thing boots up, my system really starts crawling. I have an external USB (specifics of that drive are here) which I'm thinking about moving the VM to. Obviously a USB drive is slower than my internal HDD, but maybe having two operating systems using the same disk is WORSE than putting one of them on a separate (albiet slower) disk. This a bad idea?
