  • Neo4j Windows Plugin Installation desktop V2.M06

    - by user2904850
    I have downloaded and installed the latest Window V2 Community M06 build of Neo4j on a windows 7 64 bit machine (I have tried the 32bit and 64 bit installs). Installation proceeds without and problems and the system runs normally but there is no /plugins directory (on both versions):- \Program Files (x86)\Neo4j Community\ \Program Files (x86)\Neo4j Community\.install4j \Program Files (x86)\Neo4j Community\bin I am trying to install the Spatial plugin .. so I tried creating the \plugins directory. I extracted the zip file and left the zip file in the directory but the plugins are not found:- C:\Users\WFN44217>curl localhost:7474/db/data/ { "extensions" : { }, "node" : "http://localhost:7474/db/data/node", "reference_node" : "http://localhost:7474/db/data/node/0", "node_index" : "http://localhost:7474/db/data/index/node", "relationship_index" : "http://localhost:7474/db/data/index/relationship", "extensions_info" : "http://localhost:7474/db/data/ext", "relationship_types" : "http://localhost:7474/db/data/relationship/types", "batch" : "http://localhost:7474/db/data/batch", "cypher" : "http://localhost:7474/db/data/cypher", "transaction" : "http://localhost:7474/db/data/transaction", "neo4j_version" : "2.0.0-M06" } I have tried some other plugins, but these are also not found. Any idea what might be missing?

  • Algorithm to find all tiles within a given radius on staggered isometric map

    - by kasztelan
    Given staggered isometric map and a start tile what would be the best way to get all surrounding tiles within given radius(middle to middle)? I can get all neighbours of a given tile and distance between each of them without any problems but I'm not sure what path to take after that. This feature will be used quite often (along with A*) so I'd like to avoid unecessary calculations. If it makes any difference I'm using XNA and each tile is 64x32 pixels.

  • C or assembly code to find current cpu core speed

    - by honestann
    How can my application efficiently determine the following information peroidically while it executes: 1: current speed of each of the 8 CPU cores. 2: which core the code is currently executing on. My application is C and assembly-language, so any solution in either C or assembly-language is fine. This code needs to execute quickly, so creating, reading and processing a file generated by "cat /proc/cpuinfo" is much too slow. The cores slow-down and speed-up automatically, probably to keep CPU temperature under control. Therefore, a one-time measure is not sufficient for my purposes. My application already reads and subtracts the cpu cycle counter in assembly language to determine number of clock cycles, but my program cannot compute elapsed time in nanoseconds unless it knows the current clock frequency of the cpu cores (and which core the code is executing on). Thanks!

  • Recovering domain name from a person I can't find

    - by Daniel Gruszczyk
    I have a problem with one domain and I have no idea how to go about it. I am volunteering for a small charity in Sheffield (UK), more specifically I am redoing their website. A while ago (few years) there was one guy who made that website for them, sorted out a free hosting with another charity, bought domain name etc. Since the domain name is registered in his name, and he disappeared and we have no way of finding/contacting him, we can't move it to different hosting or do virtually nothing about it. Somehow the domain is being renewed every year, we know which domain registration service provider it is registered with, we know the guys name, and that's about it. How would we go about re-registering that domain in the charity's name, instead of that guy, is that at all possible? If we happen to get in touch with him, what should we ask for? Thanks for your help.

  • Where to find clients?

    - by Zenph
    My main area: web development. Of course, I don't expect anybody give away their 'gold mine' or whatever but I am struggling to see where I should be advertising my services. I have one other developer I work with and we have a lot of happy clients - on freelance websites. Thing is, freelance websites just seem to suck the life out of you when you're being out-bidded by ridiculous rates. I want to attract customers who are more concerned about quality and accountability than price. Any suggestions at all? I'm so lost with this. EDIT: Added bounty of 200 - all of my 'reputation'. EDIT: Added second bounty of 50 I did hear of a novel idea. Do work for an opensource project and get featured in their 'trusted developers' section, if they have one. Input?

  • Nautilus tags/labels/marks/columns for folders/files

    - by madox2
    Is there any way how to mark folders or files with tags(or labels, new columns or whatever) in Nautilus? It would be nice to sort marked folders or files through this tags. Especially my first idea was to mark folders in my Movie directory with tags seen, not seen, must see, and so on. Then I realized it would be useful in any other workspaces with any custom tags... Is there any nautilus extension for this? Or any other file manager which can do this? It might look like this:

  • Routes on a sphere surface - Find geodesic?

    - by CaNNaDaRk
    I'm working with some friends on a browser based game where people can move on a 2D map. It's been almost 7 years and still people play this game so we are thinking of a way to give them something new. Since then the game map was a limited plane and people could move from (0, 0) to (MAX_X, MAX_Y) in quantized X and Y increments (just imagine it as a big chessboard). We believe it's time to give it another dimension so, just a couple of weeks ago, we began to wonder how the game could look with other mappings: Unlimited plane with continous movement: this could be a step forward but still i'm not convinced. Toroidal World (continous or quantized movement): sincerely I worked with torus before but this time I want something more... Spherical world with continous movement: this would be great! What we want Users browsers are given a list of coordinates like (latitude, longitude) for each object on the spherical surface map; browsers must then show this in user's screen rendering them inside a web element (canvas maybe? this is not a problem). When people click on the plane we convert the (mouseX, mouseY) to (lat, lng) and send it to the server which has to compute a route between current user's position to the clicked point. What we have We began writing a Java library with many useful maths to work with Rotation Matrices, Quaternions, Euler Angles, Translations, etc. We put it all together and created a program that generates sphere points, renders them and show them to the user inside a JPanel. We managed to catch clicks and translate them to spherical coords and to provide some other useful features like view rotation, scale, translation etc. What we have now is like a little (very little indeed) engine that simulates client and server interaction. Client side shows points on the screen and catches other interactions, server side renders the view and does other calculus like interpolating the route between current position and clicked point. Where is the problem? Obviously we want to have the shortest path to interpolate between the two route points. We use quaternions to interpolate between two points on the surface of the sphere and this seemed to work fine until i noticed that we weren't getting the shortest path on the sphere surface: We though the problem was that the route is calculated as the sum of two rotations about X and Y axis. So we changed the way we calculate the destination quaternion: We get the third angle (the first is latitude, the second is longitude, the third is the rotation about the vector which points toward our current position) which we called orientation. Now that we have the "orientation" angle we rotate Z axis and then use the result vector as the rotation axis for the destination quaternion (you can see the rotation axis in grey): What we got is the correct route (you can see it lays on a great circle), but we get to this ONLY if the starting route point is at latitude, longitude (0, 0) which means the starting vector is (sphereRadius, 0, 0). With the previous version (image 1) we don't get a good result even when startin point is 0, 0, so i think we're moving towards a solution, but the procedure we follow to get this route is a little "strange" maybe? In the following image you get a view of the problem we get when starting point is not (0, 0), as you can see starting point is not the (sphereRadius, 0, 0) vector, and as you can see the destination point (which is correctly drawn!) is not on the route. The magenta point (the one which lays on the route) is the route's ending point rotated about the center of the sphere of (-startLatitude, 0, -startLongitude). This means that if i calculate a rotation matrix and apply it to every point on the route maybe i'll get the real route, but I start to think that there's a better way to do this. Maybe I should try to get the plane through the center of the sphere and the route points, intersect it with the sphere and get the geodesic? But how? Sorry for being way too verbose and maybe for incorrect English but this thing is blowing my mind! EDIT: This code version is related to the first image: public void setRouteStart(double lat, double lng) { EulerAngles tmp = new EulerAngles ( Math.toRadians(lat), 0, -Math.toRadians(lng)); //set route start Quaternion qtStart.setInertialToObject(tmp); //do other stuff like drawing start point... } public void impostaDestinazione(double lat, double lng) { EulerAngles tmp = new AngoliEulero( Math.toRadians(lat), 0, -Math.toRadians(lng)); qtEnd.setInertialToObject(tmp); //do other stuff like drawing dest point... } public V3D interpolate(double totalTime, double t) { double _t = t/totalTime; Quaternion q = Quaternion.Slerp(qtStart, qtEnd, _t); RotationMatrix.inertialQuatToIObject(q); V3D p = matInt.inertialToObject(V3D.Xaxis.scale(sphereRadius)); //other stuff, like drawing point ... return p; } //mostly taken from a book! public static Quaternion Slerp(Quaternion q0, Quaternion q1, double t) { double cosO = q0.dot(q1); double q1w = q1.w; double q1x = q1.x; double q1y = q1.y; double q1z = q1.z; if (cosO < 0.0f) { q1w = -q1w; q1x = -q1x; q1y = -q1y; q1z = -q1z; cosO = -cosO; } double sinO = Math.sqrt(1.0f - cosO*cosO); double O = Math.atan2(sinO, cosO); double oneOverSinO = 1.0f / senoOmega; k0 = Math.sin((1.0f - t) * O) * oneOverSinO; k1 = Math.sin(t * O) * oneOverSinO; // Interpolate return new Quaternion( k0*q0.w + k1*q1w, k0*q0.x + k1*q1x, k0*q0.y + k1*q1y, k0*q0.z + k1*q1z ); } A little dump of what i get (again check image 1): Route info: Sphere radius and center: 200,000, (0.0, 0.0, 0.0) Route start: lat 0,000 °, lng 0,000 ° @v: (200,000, 0,000, 0,000), |v| = 200,000 Route end: lat 30,000 °, lng 30,000 ° @v: (150,000, 86,603, 100,000), |v| = 200,000 Qt dump: (w, x, y, z), rot. angle°, (x, y, z) rot. axis Qt start: (1,000, 0,000, -0,000, 0,000); 0,000 °; (1,000, 0,000, 0,000) Qt end: (0,933, 0,067, -0,250, 0,250); 42,181 °; (0,186, -0,695, 0,695) Route start: lat 30,000 °, lng 10,000 ° @v: (170,574, 30,077, 100,000), |v| = 200,000 Route end: lat 80,000 °, lng -50,000 ° @v: (22,324, -26,604, 196,962), |v| = 200,000 Qt dump: (w, x, y, z), rot. angle°, (x, y, z) rot. axis Qt start: (0,962, 0,023, -0,258, 0,084); 31,586 °; (0,083, -0,947, 0,309) Qt end: (0,694, -0,272, -0,583, -0,324); 92,062 °; (-0,377, -0,809, -0,450)

  • Command line method to find disk usage of camera mounted using gvfs

    - by Hamish Downer
    When my camera was mounted on /media I could use the standard tools (df) to see the disk usage of the card in my camera. However now the camera is mounted using gvfs, and df seems to ignore it. I've also tried pydf and discus to no avail. The camera is definitely available through nautilus, and when I select the camera in nautlius, the status bar tells me the amount of disk free. I can also open the ~/.gvfs/ folder in nautilus and right click on the camera folder and get the disk usage in a graphical way. But that is no use for a script. Are there command line tools that are the equivalent of df for gvfs filesystems? Or even better, a way to make df report on gvfs filesystems?

  • Why it is so difficult to find a good Ads SDK for Windows Phone 7

    - by help.net
    This post try to address an issue with the Microsoft Advertising SDK, the main fact that today Microsoft is still refusing access to the Ad Center worldwide. Yesterday they generously increase the number of free apps we can develop from 5 to 100. According to talks with other developers and the Windows Phone 7 team, I have the strong feeling the model of publishing free apps supported by apps is the right course to take today. This probably why Microsoft has moved to a bigger figure. Am I the only...(read more)

  • Using a site page to find out the web Template Name used in a SharePoint Site

    - by ybbest
    Today, I have created a SharePoint solution. It deploys a site page with code behind to show the web template name used in a SharePoint site. You can download the project from here. After you have deployed the project, you can see your template name from http://[site collection Name]/sitepage/WebTemplateInfo.aspx References: http://blogs.msdn.com/b/kaevans/archive/2010/06/28/creating-a-sharepoint-site-page-with-code-behind-using-visual-studio-2010.aspx http://www.devexpertise.com/2009/02/06/sharepoint-list-template-ids-and-site-template-ids/ http://blog.rafelo.com/2008/05/determining-site-template-used-on.html

  • rm on a directory with millions of files

    - by BMDan
    Background: physical server, about two years old, 7200-RPM SATA drives connected to a 3Ware RAID card, ext3 FS mounted noatime and data=ordered, not under crazy load, kernel 2.6.18-92.1.22.el5, uptime 545 days. Directory doesn't contain any subdirectories, just millions of small (~100 byte) files, with some larger (a few KB) ones. We have a server that has gone a bit cuckoo over the course of the last few months, but we only noticed it the other day when it started being unable to write to a directory due to it containing too many files. Specifically, it started throwing this error in /var/log/messages: ext3_dx_add_entry: Directory index full! The disk in question has plenty of inodes remaining: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda3 60719104 3465660 57253444 6% / So I'm guessing that means we hit the limit of how many entries can be in the directory file itself. No idea how many files that would be, but it can't be more, as you can see, than three million or so. Not that that's good, mind you! But that's part one of my question: exactly what is that upper limit? Is it tunable? Before I get yelled at--I want to tune it down; this enormous directory caused all sorts of issues. Anyway, we tracked down the issue in the code that was generating all of those files, and we've corrected it. Now I'm stuck with deleting the directory. A few options here: rm -rf (dir)I tried this first. I gave up and killed it after it had run for a day and a half without any discernible impact. unlink(2) on the directory: Definitely worth consideration, but the question is whether it'd be faster to delete the files inside the directory via fsck than to delete via unlink(2). That is, one way or another, I've got to mark those inodes as unused. This assumes, of course, that I can tell fsck not to drop entries to the files in /lost+found; otherwise, I've just moved my problem. In addition to all the other concerns, after reading about this a bit more, it turns out I'd probably have to call some internal FS functions, as none of the unlink(2) variants I can find would allow me to just blithely delete a directory with entries in it. Pooh. while [ true ]; do ls -Uf | head -n 10000 | xargs rm -f 2/dev/null; done ) This is actually the shortened version; the real one I'm running, which just adds some progress-reporting and a clean stop when we run out of files to delete, is: export i=0; time ( while [ true ]; do ls -Uf | head -n 3 | grep -qF '.png' || break; ls -Uf | head -n 10000 | xargs rm -f 2/dev/null; export i=$(($i+10000)); echo "$i..."; done ) This seems to be working rather well. As I write this, it's deleted 260,000 files in the past thirty minutes or so. Now, for the questions: As mentioned above, is the per-directory entry limit tunable? Why did it take "real 7m9.561s / user 0m0.001s / sys 0m0.001s" to delete a single file which was the first one in the list returned by "ls -U", and it took perhaps ten minutes to delete the first 10,000 entries with the command in #3, but now it's hauling along quite happily? For that matter, it deleted 260,000 in about thirty minutes, but it's now taken another fifteen minutes to delete 60,000 more. Why the huge swings in speed? Is there a better way to do this sort of thing? Not store millions of files in a directory; I know that's silly, and it wouldn't have happened on my watch. Googling the problem and looking through SF and SO offers a lot of variations on "find" that obviously have the wrong idea; it's not going to be faster than my approach for several self-evident reasons. But does the delete-via-fsck idea have any legs? Or something else entirely? I'm eager to hear out-of-the-box (or inside-the-not-well-known-box) thinking. Thanks for reading the small novel; feel free to ask questions and I'll be sure to respond. I'll also update the question with the final number of files and how long the delete script ran once I have that. Final script output!: 2970000... 2980000... 2990000... 3000000... 3010000... real 253m59.331s user 0m6.061s sys 5m4.019s So, three million files deleted in a bit over four hours.

  • Source control products that support linked/shared files?

    - by Ian Boyd
    We're interested in moving from a source control system that supports the concept of shared or linked files. A shared file means: a file modified in one project, is automatically updated changed in every other project that uses that same file. It does this without a developer having to request it, reverse-integrate it, ask for it, or even want it. We're trying to see if any other commonly used source-control systems can meet our needs, and include linked or shared files. My limited research shows that: Team Foundation Server doesn't support sharing files Subversion doesn't support sharing files (including Externals) CVS doesn't support sharing files (including Modules) Anything else? (besides our current source control product, obviously) References Subversion and shared files across repositories/projects? How to share files between CVS projects? Will TFS ever support shared files for projects under source control?

  • How to find a Window which should be visible on Ubuntu 14.04

    - by Bernard
    In Ubuntu 14.04 I have Keepass2 in my Launchbar. I do execute Keepass and I can see it is executing by a small arrow. With statement : ps - fu bernard | grep keepass2 Also with alt-tab I see Keepass. If I click on the Keepass icon still I am not switched to Keepass. The same happened to me with XAMPP from https://www.apachefriends.org so it seems a general Ubuntu 14.04 problem I execute this in Virtualbox client. If I switch sometimes to other VB client, when I come back the Windows is visible.

  • How to keep "dot files" under version control?

    - by andrewsomething
    Etckeeper is a great tool for keeping track of changes to your configuration files in /etc A few key things about it really stand out. It can be used with a wide variety of VCSs: git, mercurial, darcs, or bzr. It also does auto commits daily and whenever you install, remove or upgrade package. It also keeps track of file permissions and user/group ownership metadata. I would also like to keep my "dot files" in my home directory under version control as well, preferably bazaar. Does anyone know if a tool like etckeeper exists for this purpose? Worst case, I imagine that a simple cron job running bzr add && bzr ci once or twice a day along with adding ~/Documents, ~/Music, ect to the .bzrignore Anyone already doing something similar with a script? While I'd prefer bazaar, other options might be interesting.

  • Backup files with rsync: error 23

    - by maria
    Hi I'm trying to make a backup of my /home to transfer all data from one computer to another. I wanted to save the backup on the same computer and than transfere it to another one. For safety reasons, I'm trying to learn how does it work on the computer without a lot of data (the new one) to be sure I won't delete something instead of copying it. I've run in terminal: sudo rsync -avz /home/maria /home/guest/backup and I had as the result: sent 58797801 bytes received 23050 bytes 4705668.08 bytes/sec total size is 100202958 speedup is 1.70 rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1060) [sender=3.0.7] I've tried once again, with the same result. I have no idea, which files were not transferred, what makes the whole backup useless for me (I wanted to do it automatically in order not to forget about something and loose it). On both computers I have the same system (Ubuntu 10.04). Rsync version: 3.0.7-1ubuntu1. Thanks for any tips

  • CodeGolf : Find the Unique Paths

    - by st0le
    Here's a pretty simple idea, in this pastebin I've posted some pair of numbers. These represent Nodes of a unidirected connected graph. The input to stdin will be of the form, (they'll be numbers, i'll be using an example here) c d q r a b d e p q so x y means x is connected to y (not viceversa) There are 2 paths in that example. a->b->c->d->e and p->q->r. You need to print all the unique paths from that graph The output should be of the format a->b->c->d->e p->q->r Notes You can assume the numbers are chosen such that one path doesn't intersect the other (one node belongs to one path) The pairs are in random order. They are more than 1 paths, they can be of different lengths. All numbers are less than 1000. If you need more details, please leave a comment. I'll amend as required. Shameless-Plug For those who enjoy Codegolf, please Commit at Area51 for its very own site:) (for those who don't enjoy it, please support it as well, so we'll stay out of your way...)
