• Apple Remote Desktop and Screen Sharing

  - by jfm429

  We have a Mac OS 10.8.2 server that we want to be able to administer with Apple Remote Desktop. At the same time, we want normal users to be able to access their account screens (through background login) without being able to view the current screen. However, in order to enable this (by enabling the "normal" Screen Sharing option in System Preferences) Remote Desktop needs to be disabled. The question is - how can we run both Remote Desktop for administrators and VNC screen sharing for normal users while restricting normal users to logging in on a background window instead of viewing the front screen?

• Accessing subfolders of a windows share from linux

  - by Born2Smile

  Hi, at my work they have a funny setup: my home folder is a subfolder to a share, as such: \\server\share\subfolder Now I have full permissions to the subfolder, but no permissions to share. From windows I can connect to the VPN of my work place, type the above address into any address field, and voila: I see the contents of my home folder. In Linux (using Ubuntu) however, I can't figure out how to connect directly to the subfolder. Every attempt I can think of keeps returning "Access denied", because I don't have permission to view the share. Any help on how to connect to the subfolder would be greatly appreciated :) Cheers, Born2Smile

• Preview.app only auto-refreshes if you alt-tab to it.

  - by dreeves

  I'm working on a program that generates an image. I can keep the image open in Preview and when the image changes, Preview refreshes it, but only when I alt-tab (sorry, command-tab) to it. I'd like to keep the image in view and have it auto-refresh without touching it. Is that possible? (One ridiculous way I've found to do this is with a script that converts the image to a PDF file which I can keep open in Skim.app (a PDF reader) which has that ability.)

• wamp server REDIRECT_STATUS

  - by user143039

  I have noticed my remote server returns $_SERVER[REDIRECT_STATUS] with every request. Example: [REDIRECT_STATUS] = 200 But my localhost wamp server does not. Interestingly, when I manually set a header: Example: header('HTTP/1.1 302 Redirect This'); The variable: $_SERVER[REDIRECT_STATUS] is still not set. Though I can view the headers, including the one I set, with HttpFox. $_SERVER[REDIRECT_STATUS] is set when .htaccess throws(?) an ErrorDocument, like ErrorDocument 404 for example. Any ideas how to get wamp server to set the variable $_SERVER[REDIRECT_STATUS] with every request?

• How does the "Last Result" column of Scheduled Tasks in Windows Server 2003 get set from a process or script?

  - by leeand00

  The Last Result column of the Scheduled Tasks Window on Windows Server 2003, displays the result of the execution of the .exe, .vbs, .ps1, .bat, .cmd, etc... that has been run at the scheduled time. There is also an archived history of this value that appears in the Scheduled Tasks Log (Found on the Scheduled Tasks Window under the Advanced->View Log) Now my question is, if I'm running a scheduled task that is a .exe, .vbs, .ps1, .bat, .cmd, etc... how do I use that process to return a specific Last Result when the process ends? P.S. If you think this question should be split up into smaller parts since I'm painting pretty broadly with it, just let me know and I'll split it into subsequent smaller questions

• Help with design structure choice: Using classes or library of functions

  - by roverred

  So I have GUI Class that will call another class called ImageProcessor that contains a bunch functions that will perform image processing algorithms like edgeDetection, gaussianblur, contourfinding, contour map generations, etc. The GUI passes an image to ImageProcessor, which performs one of those algorithm on it and it returns the image back to the GUI to display. So essentially ImageProcessor is a library of independent image processing functions right now. It is called in the GUI like so Image image = ImageProcessor.EdgeDetection(oldImage); Some of the algorithms procedures require many functions, and some can be done in a single function or even one line. All these functions for the algorithms jam packed into ImageProcessor can be pretty messy, and ImageProcessor doesn't sound it should be a library. So I was thinking about making every algorithm be a class with a shared interface say IAlgorithm. Then I pass the IAlgorithm interface from the GUI to the ImageProcessor. public interface IAlgorithm{ public Image Process(); } public class ImageProcessor{ public Image Process(IAlgorithm TheAlgorithm){ return IAlgorithm.Process(); } } Calling in the GUI like so Image image = ImageProcessor.Process(new EdgeDetection(oldImage)); I think it makes sense in an object point of view, but the problem is I'll end up with some classes that are just one function. What do you think is a better design, or are they both crap and you have a much better idea? Thanks!

• Filtering ToDo List in Outlook 2010 with multiple Exchange accounts

  - by David LaRocque

  I'm trying to figure out how to get the ToDo list filtered for just one account? I've tried customizing the view, and using the advanced filter to get just one Oulook Data file, but once I do that the filter goes bonkers and I get all sorts of results! I know it's a combination of email flags and true tasks, and tried combining filters to pull those conditions together, and simply can't get it to cooperate. Before 2010, when the only way to get multiple mailboxes was to add additional mailboxes to the primary account, the task list pulled from just the primary account - but of course, the secondary accounts are not cached and available offline.

• What software can I use to get statistics about the programs I use most? [closed]

  - by pinouchon

  I am looking for software that reports statistics about my program usage over time. It should display output something like this (numbers are made up): Program usage today: Youtube (Chrome) 42:10 9.42% NetBeans 30:52 6.33% Google search (Chrome) 12:03 3.20% Windows explorer 5:43 1.54% Putty 2:23 0.89% ? ? ? Features I look for: Advanced statistics: ability to view a chart, to see statistics today, this week, this month. Program usage should be based on the title of the active window. The time where the user is idle shouldn't count. Ability to group some windows title together, for example, I want to group titles as Stack Overflow and * - Stack Overflow together, same thing for every website and explorer windows. Do you know a program that does something similar?

• How do I correctly display special characters in my Firefox browser?

  - by BrianH

  (Firefox 3.6.13 on Windows XP) Every once in a while I notice an odd character on certain web pages when browsing the web. It is a outline of a box with a 4-digit number inside. And example of a page that has these characters is: http://aws.amazon.com/ec2/#highlights After each section heading (Elastic, Completely Controlled, ...) I see a box with the number "0096" inside. I looked at the cached version on Google, and google has &ndash; in it's place, so I'm guessing I should be seeing a dash there instead of the box with the numbers in it. I have tried changing the character encoding in Firefox but haven't been able to find one that shows these characters correctly. Is there a way to allow Firefox to view these characters? Thanks in advance!

• Why blogger puts BR tags only when content served via RSS feed?

  - by tamashumi

  I have a problem with using my new blog RSS feed. I wrote a post (the first one) with some code examples formatted by SyntaxHighlighter. To paste a code sample I'm switching from WYSIWYG to HTML view and put the code inside pre tag like this (don't worry, h4 tag was opened a line above the screenshot area): The problem is that such pre tag, when later accessed via RSS feed contains br tags instead of new line characters. Below is screenshot of the adequate RSS source code: What's most important when accessed via www, the post html is formatted fine, no brs inside pre. I verified that by downloading the blog post with wget. So I believe this isn't SyntaxHighlighter issue nor any 'new line' formatting on blog post save. This is a real problem as I want aggregate my blog on employers blog and all formatting of code examples is broken because of that. The base question is: how to get rid of those unwanted brs served via RSS? What's strangest friend of mine also uses blogger for such aggregation and he has no such issue. I checked his RSS feed and there are no brs inside pre tags. We also compared settings of our blogs. However we have found no clue. The blog post RSS for the blog (just check source and search for string: pre class="brush) Mentioned friend's blog Last thing: I see content served from RSS is now also html encoded. If I remember well, it wasn't previously.

• Hiding a directory through the FAT table

  - by hennobal

  I've looked into the FAT file system, trying to find a way to make a directory hidden from view of the user. This has been done with malware previously, so it should be possible. The SpyEye trojan hid inside a directory C:\cleansweep.exe\ which was only reachable through the command line. I know deletion is possible by substituting the first character of the directory in the FAT table with 0xE5, but then it will not be accessible. Any ideas on how the scenario from SpyEye can be recreated? Any filesystem is interesting, but ideally FAT or NTFS.

• [linux] preventing access in shared hosting

  - by jack

  Hi Linux Admins I set up a small shared hosting that contains some sites. For each site, there is a user. I mean, for abcd.com, I created abcd.com user and put htdocs for web hosting. I have no idea on how to prevent abcd.com from accessing xyzd.com's data. I have chmoded by changing 0 to others permission, which makes access defined by Apache when I view it with browser. How can I secure access? Thanks.

• Internet Explorer cannot download rss.php

  - by davethegr8

  Whenever I try to go to an RSS feed in IE7 directly, I get a very strange error. IE 7 tries to download the page, but fails. It throws an error, Internet Explorer cannot download rss.php from www.example.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. But when I click a link to view the same feed, it doesn't throw an error but displays the XML instead. Are there any ways I caan fix this, that don't involve OS hacks? Also, if I try to put an xsl stylesheet on it, it tries to download the file no matter what and still errors.

• What are the advantages to use vector-based fonts over bitmap fonts in (2d) games?

  - by jmp97

  I know that many games are using bitmap fonts. Which are the advantages for vector-based font rendering / manipulation when compared to bitmap fonts and in which scenarios would they matter the most? Prefer a focus on 2d games when answering this question. If relevant, please include examples for games using either approach. Some factors you might consider: amount of text used in the game scaling of text overlaying glyphs and anti-aliasing general rendering quality font colors and styling user interface requirements localisation / unicode text wrapping and formatting cross-platform deployment 2d vs 3d Background: I am developing a simple falling blocks game in 2d, targeted for pc. I would like to add text labels for level, score, and menu buttons. I am using SFML which uses FreeType internally, so vector-based features are easily available for my project. In my view, font sizes in simple games often don't vary, and bitmap fonts should be easier for cross-platform concerns (font-formats and font rendering quality). But I am unsure if I am missing some important points here, especially since I want to polish the looks of the final game.

• Portable Display doesn't work anymore

  - by RipCord

  My USB portable monitor will not work since I installed the hard drive onto an HP laptop. I have installed all the new hardware drivers and do not have any more device issues in device manager view. My old laptop was a lenovo. The new one is an HP. The system seems to recognize devices that I connect via, usb but the portable display still does not show anything on the screen. It is probably a conflict in the registry but I'm not sure how to find it and the Power User does not have the luxury of letting me troubleshoot for hours to isolate the problem.

• Unable to remove/hide icons from desktop folder

  - by Kyomu

  I wish to hide some windows icons from my desktop folder1, but cannot. When I click delete, it says they will be deleted from my desktop (which they already are), but they remain visible in the desktop folder, which is where I wish them removed. Is there any way I can remove these? (I always use Win+E which really lets me get to all of these easy enough). Offending icons: Libraries, Homegroup, User folder, Computer, Network, Control Panel, and Recycle Bin. For those who might be wondering why, I find myself in this folder a bit to often (including when uploading a file), and find these nothing but clutter, especially as these always default to the top. Thanks for your help! 1 By desktop folder, I mean the folder you would see by going to "My Computer" and clicking "Desktop" on the top left under Favorites. Note: Changing my "Desktop Icon Settings" under "Personalize" does not affect the desktop folder, but rather just the desktop view.

• Need to transfer large video from Camera!-app to computer

  - by Henrik Söderlund

  I have a jailbroken iPhone 4S and am trying to transfer a 25minute long HD-video that I have recorded through SmugMug's Camera-Awesome (Camera!) app. Once recorded in the app, it stays within that app's interface until you choose to save it via the app onto the camera roll. When trying this option, the app just stalls, even when leaving it for an hour plus. I assume the video is too large to copy. I am trying the iExplorer app on my MacBookAir. I can find the Documents folder inside the Camera!-folder. But as soon as I access it to view the contents, it simply stalls the app completely. Probably after trying to read the enormous video. Is there a clever way to transfer this file onto the computer? I can use iFile on the iPhone to transfer through wifi, but I don't know the Camera! app's Documents folder location on the file system.

• Swap files in Cloud Infrastructures

  - by ffeldhaus

  At our company we set up an OpenStack Cloud and are currently creating internal guidelines for creation of OS templates / images. One controversial topic was if we should provide swap inside the VM templates. Therefore I'd like to ask the following questions From an elastic Cloud provider point of view, does it make sense to offer swap partitions / files in the VM templates or is swap not needed when a VM can be resized? Which scenarios necessarily demand a swap file to be present? What kind of Storage should be used for swap files (e.g. local / central, FC / iSCSI / NFS)? Are there any best practices for offering swap files in a performant way in Cloud Infrastructures?

• Cube rotation DX10

  - by German

  Well I'm reading the Frank's Luna DirectX10 book and, while I'm trying to understand the first demo, I found something that's not very clear at least for me. In the updateScene method, when I press A, S, W or D, the angles mTheta and mPhi change, but after that, there are three lines of code that I don't understand exactly what they do: // Convert Spherical to Cartesian coordinates: mPhi measured from +y // and mTheta measured counterclockwise from -z. float x = 5.0f*sinf(mPhi)*sinf(mTheta); float z = -5.0f*sinf(mPhi)*cosf(mTheta); float y = 5.0f*cosf(mPhi); I mean, this explains that they do, it says that it converts the spherical coordinates to cartesian coordinates, but, mathematically, why? why the x value is calculated by the product of the sins of both angles? And the z by the product of the sine and cosine? and why the y just uses the cosine? After that, those values (x, y and z) are used to build the view matrix. The book doesn't explain (mathematically) why those values are calculated like that (and I didn't find anything to help me to understand it at the first Part of the book: "Mathematical prerequisites"), so it would be good if someone could explain me what exactly happen in those code lines or just give me a link that helps me to understand the math part. Thanks in advance!

• frequent abnormal shutdowns/system crashes

  - by user110353

  It's been almost 5 days since I have installed Ubuntu and almost 6th time that my laptop has been crashed entirely and it shuts down abnormally. Actually, it heats up and I have to wait for 20 odd minutes before I can turn it on again. A message appears that my PC crashed due to overheating which may damage my hard disk. The crashes happened when I tried to open some application that freeze my PC not even giving me enough time to go to system monitor and end process. Sometimes the culprit application which caused crash is Ever-pad, sometime it's team-viewer, sometimes it's some other. This is something very serious. The last crash occurred at 09:14:40. Kindly click here to view system log. I want to stick to Ubuntu and the same laptop as I had serious issues with Windows and I nearly went out to dump my laptop and purchase a more powerful system. Below are my hw/os specs. Kindly advice on how to resolve this issue Ubuntu 12.10 Kernal 3.5.0-18-generic GNOME 3.6.0 Memory 2.0GB Processor: Genuine Intel CPU [email protected] x 2 Available Disk Space: 63.7 GB Thanks in advance

• How can # of unique visitors be more than # of visits?

  - by Dallas

  I am confused as heck. When looking at a few individual pages, I am seeing weird results I hope someone can help explain. I am doing manual standard reports, and not creating or using a widget. For each of the two tests below, the metrics I am using are visits (not visitors) and unique visitors. I am using Page as my primary dimension and Page Title as secondary. I am filtering to include certain Pages. Example 1 - Looking at a single page... I see 731 unique visitors and 169 visits. How is this possible? Does google just flip them around for some reason? Example 2 - Looking at several pages combined... If you examine the timeline below , you can see that the numbers are all over the place. How is it possible to have more unique visitors than visits? What am I missing? I would suspect that if things were just flipped around, then I should still see one line that is always below the other line. Anyone clue me in to what may be happening here? I also notice that the visits column (just out of view) adds up to the total, but the unique visitors column clearly doesn't.

• Troubleshooting web page load issues

  I having an odd issue where a particular page doesn't finish loading... all the time. Intermittenly, this page doesn't finish loading - in particluar, it seems maybe the JS file isn't downloaded or finished loading. Marchelos Law I am not sure how to troubleshoot this issue, since refreshing it fixes it. I see it mostly in IE 7 & 8, rarely in Safari or FireFox. If you view the page in question, refreshing it - you should see the issue. Any ideas?

• Only allow root to change filesystem

  - by Uejji

  The VPS I manage uses a simple hard link rsync archive daily backup system saved to a loop file. This is great, because each backup only takes up as much space as what has changed each day, and all user/group permissions are kept. I would like to give users direct access to their home directories in each backup, but I'm worried about intentional or accidental backup data destruction, as how it stands now users can actually change, destroy or add to backed up data they originally owned. I've been looking for a way to mount this filesystem similar to an ro mount option, but something that would still allow rw access to root, but I've had absolutely no luck. In other words, I want users to be able to view and copy their backed up data without actually being able to change it, and have that data maintain the original permissions. I've got no real preferences as far as filesystem, as long as it's a standard unix filesystem that can preserve permissions, support hard links and deny write access to users without actually stripping the w permission from everything.

• Why OpenDialog.py don't work on Jotty application

  - by venerable13

  I'm a Python beginner, I installed quickly, I wrote a "quickly tutorial" in terminal and I did all the steps before at: "However, the application is not complete. There are a few things left for you to do:" All the next steps aren't finished yet because when I use open dialog and select one of the files saved, the content of the file isn't showed on "textview1", Why? Only is deleted the content written. Before if was used without dialog works great. SaveDialog.py work great. -def on_mnu_new_activate(self, widget, data=None) don't work neither. -If I use the bold lines by the others don't work. ###def open_file(self, widget, data=None): def on_mnu_open_activate(self, widget, data=None): ###def save_file(self, widget, data=None): def on_mnu_save_activate(self, widget, data=None): To view the code, go to the link above, unrar the archive, install "quickly" if you don't have it yet, place inside on jotty directory, then put "quickly run", "quickly edit", "quickly design", depending what do you want to do. Code - problematic code with OpenDialog implemented. Code-part1 - works OK, but without OpenDialog. I need principally that OpenDialog function work great.
