  • How can I correctly display my AVL Tree in LaTex? A solo left-child hangs straight down....

    - by cb
    The below code almost works perfectly, however the child of 9, 7, hangs straight down instead of as a left-child. How can I correct this? \usepackage{tikz} \usepackage{xytree} \begin{tikzpicture}[level/.style={sibling distance=60mm/#1}] \node [circle,draw] {4} child { node [circle,draw] {2} child {node [circle,draw] {1} } child { node [circle,draw]{3} } } child {node [circle,draw] {6} child {node [circle,draw] {5} } child {node [circle,draw] {9} child {node [circle, draw] {7}} } }; \end{tikzpicture}} Thanks, CB

  • iPhone 3.1 Black Screen

    - by churnd
    Since I've updated my 3G iPhone to 3.1, it will become unresponsive after ~4-5 hours. It looks like it's off, but it's not. None of the buttons do anything that I can see. The only way I can get a screen back is to do a hard reset (Power + Home). Has anyone else had this problem? What can I do to fix it? I've had it 3 happen 3 times already. Very annoying. Apparently, the Discussions forum on Apple.com also shows lots of people are having the same problem. One guy said he did a restore and that fixed it for him, which I haven't tried yet because many others also tried that and it didn't help. A few others have said turning off WIFI fixes it for them, so I'm going to try that today. Another thing I've noticed is that now, when I plug in my iPhone to my Macbook Pro, iTunes 9 does not launch. It used to before the update. ** Further update and possible solution ** I left my iPhone plugged into my Macbook Pro yesterday while at work, and didn't use it much throughout the day. I noticed it didn't lock up once. I suspect this was because it was connected to a power source. I continued to use my iPhone with no problem yesterday and today. Still no lockups as of now. I personally think this was Spotlight and/or Genius "doing it's thing" from a new install. Kinda like an OS upgrade on your Mac... Spotlight has to rebuild itself and those first couple of hours can be kinda sluggish. This would be even more so on the iPhone where processing power is limited, and I'm sure the processor is clocked down a bit while on battery power, which would further amplify the problem. Again, just my guess. My iPhone is working fine now. ** Final Solution ** Update to 3.1.2. Problem solved.

  • Linux software to maintain old/backup versions of directory tree

    - by Bittrance
    I am replacing an old Linux file server serving NFS and CIFS. For the new server (still serving CIFS and NFS), I would like to have software that automatically and efficiently maintains old revisions of files in parallel trees, so that they can be accessed by users without special tools. I am looking for software that is akin to Time Machine or Flyback, but works well on a server. The dataset is some 10000 files weighing maybe 60 GB. Changes are relatively few, usually less than 100 files changes daily. Using LVM snapshots will not cut it, as the old revisions must reside on a separate set of disks from the live data. Edit: To clarify: keeping old revisions is non-vital addition to the solution, so any suggestion will have to stay in the range of some hundred euros.

  • Correcting owner/permissions on damaged directory tree in linux

    - by mcs130
    I inadvertently made a backup copy of a directory recursively and forgot the -a (--preserve) switch when doing so. This damaged my backup directory (which contains data we need to access). The directory and all of its child folders and files comprise an installation of an application including postgress DB and solr files. The original copy was used to for a failed re-config attempt. Now I need to use the backup copy to start over, only the ownership of the backup copy is now root across everything and it is no longer usable (processes won't run due to ownership problems I created when I forgot the -a on the cp -r). I've re-installed a clean copy of the application into a 3rd location now (which has the correct owner/perms) and need to copy the owner/perms from this good directory over onto the damaged directory. What is the best way (if even possible) to do this. (I've Googled and seen things from perl scripting to setfacl/getfacl to do this but am unfortunately still confused). Apologies if this seems a dumb question. Thanks.

  • Subversion all or nothing access to repo tree

    - by Glader
    I'm having some problems setting up access to my Subversion repositories on a Linux server. The problem is that I can only seem to get an all-or-nothing structure going. Either everyone gets read access to everything or noone gets read or write access to anything. The setup: SVN repos are located in /www/svn/repoA,repoB,repoC... Repositories are served by Apache, with Locations defined in etc/httpd/conf.d/subversion.conf as: <Location /svn/repoA> DAV svn SVNPath /var/www/svn/repoA AuthType Basic AuthName "svn repo" AuthUserFile /var/www/svn/svn-auth.conf AuthzSVNAccessFile /var/www/svn/svn-access.conf Require valid-user </Location> <Location /svn/repoB> DAV svn SVNPath /var/www/svn/repoB AuthType Basic AuthName "svn repo" AuthUserFile /var/www/svn/svn-auth.conf AuthzSVNAccessFile /var/www/svn/svn-access.conf Require valid-user </Location> ... svn-access.conf is set up as: [/] * = [/repoA] * = userA = rw [/repoB] * = userB = rw But checking out URL/svn/repoA as userA results in Access Forbidded. Changing it to [/] * = userA = r [/repoA] * = userA = rw [/repoB] * = userB = rw gives userA read access to ALL repositories (including repoB) but only read access to repoA! so in order for userA to get read-write access to repoB i need to add [/] userA = rw which is mental. I also tried changing Require valid-user to Require user userA for repoA in subversion.conf, but that only gave me read access to it. I need a way to default deny everyone access to every repository, giving read/write access only when explicitly defined. Can anyone tell me what I'm doing wrong here? I have spent a couple of hours testing and googling but come up empty, so now I'm doing the post of shame.

  • Dead letter bin / black hole email address

    - by skypanther
    I'm looking for an email address that can be sent to where the mail will just be deleted without a bounce back. RFC 2606 defines example.com as a fictitious domain for documentation. Is there something similar for email? This will be used in printed documentation, needs to be stable (the domain can't go stale or replaced by an NSFW site), and as generic as possible.

  • Black stripe appears to the right of the screen, impossible to get rid of

    - by Gabriele Cirulli
    After clicking the "Auto Config" button on my Acer AL2216w screen a stripe appeared on the right of the screen where the screen doesn't "exist" and I can't seem to take the screen viewport back even by using the OCD setting and moving it to the right. The left part of the screen is also hidden and I'm not able to see what's going on there. The PC is connected to the screen through a DVI adapter and a VGA cable. I also use multiple monitors and this is the second monitor. Anyway this seems not to be a related issue, as this used to happen even when I only had a single monitor. I managed to fix this issue once but it was more than two years ago and I can't remember what I did, and out of all of the things I've tried so far (connecting the screen to another PC and performing auto adjustment, switching the cables, etc.) none worked. Here's how it looks: Can anyone help me fix this?

  • Web-based SVG or JavaScript Org Chart or Tree Graph Plotting Visualization API

    - by asoltys
    Hi, I'm looking to build an interactive web-based org chart for a large organization. I somewhat like the interface at ancestry.com where you can hover over people and pan/zoom around and click on different nodes to make them the root. Ideally, I'd like it if people could belong to multiple organizational entities like committees, working groups, etc. In other words the API should support graphs in general, not just trees. I'd like to be able to visually explode each organizational substructure into substituents by clicking on it, with a nice animation of the employees ballooning or spilling out so you can really interactively drill down through the organization. I found http://code.google.com/apis/visualization/documentation/gallery/orgchart.html but it looks a bit rudimentary. I know there are desktop tools like OrgPlus and Visio that can build static charts but I'm really looking for a free, web-based API with open standards-based output like SVG or HTML5 Canvas elements rather than Flash or some proprietary output. Something I can embed into a custom web application and style myself. Something interactive.

  • black and white pages not recognized by printer

    - by user46627
    I have a document which has color on about 25% of its pages. When I print it in the copy shop, the printer's technically supposed to recognize the b/w pages. However, all pages are registered as colored, i.e. the pages are color-enabled pages which happen to not have any colors on them (but I'm paying for the color-enabled-ness). Regrettably, the staff have to charge me for color because the printer's leased and they have to pay for color pages, so showing them that there's no color doesn't help me. What are possible sources for b/w pages showing up like that?

  • Directory tree in a Resource without extraction...

    - by Corelgott
    Hi all, i am looking for a way to store a complete directory including sub directories in an application's resource and not have to extract it to use it. Details: We would like to use GeckoFx (Gecko as C# Component) in one of our applications. GeckoFX needs the XUL-Runner and needs to find it's folder structure We have some other data which I would not prefer to extracted to the customer's pc; At least not onto something persistent like a hdd... Getting the complete directory into the resources is not that kind of a big deal. Compress to one file and done. But not writing it to the disk to use it is something else. I have a strong dislike against temp folders and such things. Would anything like a RAM drive be possible? Some part of the RAM beeing mounted? Does something like this even exist as a lib, or would this only be possible by a device driver? Any thoughts on this? Thanks in advance! Corelgott

  • creating decision tree based troubleshooting documentation?

    - by Joseph
    We troubleshoot a lot of server and network issues and follow a loose set of steps on what to do in different cases. With more and more people and responsibility, the need for standardization is needed so we don't miss something. I know I could accomplish what I want using flowcharts, but I'd like to do something similar to a "Choose Your Own Adventure" style. I think this is pretty much the same as what support call centers seem to do. Are there any tools to make creating such documentation easier? I'm looking for a web based approach if possible.

  • Zipping folder with absolute path without keeping tree of folders

    - by Preston
    I am attempting to use the zip -r command to zip a folder which includes two files. I need to pass the absolute path of the folder with two files (/path/to/my/files/), which is causing all of the folders to be zipped with it, where as I only need the last folder (files/) and its contents to be zipped, so that when the file is unzipped, there is only one folder and the two files within it. How can I modify the command to be able to pass the absolute paths in the arguments while keeping only the last folder?

  • Make symlink on Windows of whole tree without modifying the original folder

    - by DarkGhostHunter
    I'm trying to do this: make a symlink of a whole directory "C:/Master", in different folders like "C:\Projects\Alpha\", "C:\Projects\Beta\" an so on. "Master" directory usually changes in files and data. I work on the "Projects/*", where every project folder uses the "Master" files, but every one has new files in them. Let's say, I point to the car engine in every project folder, and inside them I add different kind of wheels. The problem I'm having, as a Windows 8 user, is that symlinks (junction) acts as a window to "Master" - I'm not allowed to add any file inside. I looking a way to reference the entire "Master" directory, and add new files - not edit any of the "Master" ones. It's as described here, but on Windows.

  • Replaced CPU and black screen but no beep?

    - by luke
    I'm having a bit of trouble with a GIGABYTE GA-MA78G-DS3H (rev. 2.0) motherboard. Recently when trying to clean my AMD Phenom II X 4 CPU, I dropped it and broke some pins. I have now brought a Athlon 64 X2 5400+. However, it does not seem to work. To begin with, I cleared the CMOS via the jumper located near the battery. This was because I had my AMD Phenom II overclocked and did not wish for the same voltage to go to the new CPU. I then tried booting with the monitor plugged into the chipsets VGA but no luck. No signal was sent to the monitor, and the monitor just went into standby. I then tried it off the graphics card but the same happened again. Then I tried to check whether the CPU could executed some BIOS codes by stripping the RAM out and making sure a speaker was plugged in but no beeps could be heard. I replaced the speaker and tried again but no luck. The CPU is brand-new so what is going wrong?

  • Computer not booting, black screen, no beeps

    - by Michael Gaddass
    I bought a pre-owned computer on Ebay. It booted fine, had to reset due to it not detecting USB mouse, but it detected the USB keyboard. Booted fine again, then I tried to install Ubuntu Desktop, when it was installing I got a phone call, when I'm answering it, I find a Blue screen of Death. I reboot the computer and nothing, no BIOS boot, no beeping, but one of the fans was on. I opened the cover and found a large amount of dust, removed it, still not booting. I'm a complete novice with computer repairs, the most advanced thing I did was take a 286 harddrive and replace a 486's damaged harddrive with it (put the drive into the 486 that is), what could possibly be causing this?

  • Fastest security check of file tree on NFS

    - by fungs
    I am currently experiencing very bad performance using the following on an NFS network folder: time find . | while read f; do test -L "$f" && f=$(readlink -m $f); grp="$(stat -c %G $f)"; perm="$(stat -c %A $f)"; done Question 1) Within the loop permissions are checked using the variables grp and perm. Is there a way to lower the amount of disc I/O for these kind of checks over the network (e.g. read all meta data at once using find)? Question 2) It seems like the NFS isn't tuned very well, the same operation on a similar network link via SSHFS take only one third of the time. All parameters are auto-negotiated. Any suggestions?

  • VMware vSwitches and spanning tree

    - by dunxd
    I have two redundant core switches I want to connect to a new vSwitch I am setting up on a VMware ESX host. The switch will have two physical NICs each of which will connect to one of the core switches. The core switches are connected. If this was a physical switch, I would worry about connecting it to both core switches, because this would create a network loop. Do I need to worry about this for a VMware virtual switch? VMware's documentation says it is not possible to connect two vSwitches in a loop, therefore STP is not required. However, I am worried about connecting two physical switches together via a vSwitch.

  • External monitor turning black intermittently

    - by coding crow
    I have installed an external monitor (Dell ST2220L, 21.5 inch) on my laptop (Sony Vaio). I am using a DVI-D cable for connection. Since the laptop does not have a DVI-D port, I have connected a DVI-D to HDMI connector on the laptop end and inserted the cable in HDMI port of the laptop.. I have switched off the laptop display and adjusted the screen resolution on the Dell external monitor to 1920 x 1080 and adjusted colors for the Windows 7 and brightness and contrast from the monitor. The problem is the monitor turns of blank intermittently for 1-2 seconds and turns on again at random interval. What could be the reason for this and how to get rid of this problem?

  • Most efficient way of creating tree from adjacency list

    - by Jeff Meatball Yang
    I have an adjacency list of objects (rows loaded from SQL database with the key and it's parent key) that I need to use to build an unordered tree. It's guaranteed to not have cycles. This is taking wayyy too long (processed only ~3K out of 870K nodes in about 5 minutes). Running on my workstation Core 2 Duo with plenty of RAM. Any ideas on how to make this faster? public class StampHierarchy { private StampNode _root; private SortedList<int, StampNode> _keyNodeIndex; // takes a list of nodes and builds a tree // starting at _root private void BuildHierarchy(List<StampNode> nodes) { Stack<StampNode> processor = new Stack<StampNode>(); _keyNodeIndex = new SortedList<int, StampNode>(nodes.Count); // find the root _root = nodes.Find(n => n.Parent == 0); // find children... processor.Push(_root); while (processor.Count != 0) { StampNode current = processor.Pop(); // keep a direct link to the node via the key _keyNodeIndex.Add(current.Key, current); // add children current.Children.AddRange(nodes.Where(n => n.Parent == current.Key)); // queue the children foreach (StampNode child in current.Children) { processor.Push(child); nodes.Remove(child); // thought this might help the Where above } } } } public class StampNode { // properties: int Key, int Parent, string Name, List<StampNode> Children }
