  • Simple Java Applet not loading in FireFox / Safari on MacOS

    - by Sleepless
    Hello all, I'm probably missing something very basic here. I'm trying to get my first applet to run inside a local HTML page in Firefox 3.6 on Mac OS 10.5.8. Here's the applet's code: package SimpleApplet; import java.applet.Applet; import java.awt.*; public class MyApplet extends Applet { private static final long serialVersionUID = 1L; public void init() { } public void stop() { } public void paint(Graphics g) { g.drawString("Tweedle-Dee!",20,40); } } Here's the HTML page: <html> <body> Here's the applet: <br/> <applet code="MyApplet.class" width="300" height="150"> </applet> </body> </html> Both files (.class and .html) are in the same folder on my local machine. Now when I load the .html file into Firefox, a rectangle with a red X gets displayed. The applet works when started from Eclipse (using JRE 1.5 BTW). Also, it's not a general problem with my browser, as several pages with applets (e.g. http://java.sun.com/applets/jdk/1.4/demo/applets/Blink/example1.html) work. This is also difficult to troubleshoot because there is no output at all on the Java console... Any suggestions are appreciated!

  • How to poll a file in /sys

    - by Bjoern
    Hi, I am stuck reading a file in /sys/ which contains the light intensity in Lux of the ambient light sensor on my Nokia N900 phone. See thread on talk.maemo.org here I tried to use pyinotify to poll the file but this looks some kind of wrong to me since the file is alway "process_IN_OPEN", "process_IN_ACCESS" and "process_IN_CLOSE_NOWRITE" I basically want to get the changes ASAP and if something changed trigger an event, execute a class... Here's the code I tried, which works, but not as I expected (I was hoping for process_IN_MODIFY to be triggered): #!/usr/bin/env python # -*- coding: utf-8 -*- # import os, time, pyinotify import pyinotify ambient_sensor = '/sys/class/i2c-adapter/i2c-2/2-0029/lux' wm = pyinotify.WatchManager() # Watch Manager mask = pyinotify.ALL_EVENTS def action(self, the_event): value = open(the_event.pathname, 'r').read().strip() return value class EventHandler(pyinotify.ProcessEvent): def process_IN_ACCESS(self, event): print "ACCESS event:", action(self, event) def process_IN_ATTRIB(self, event): print "ATTRIB event:", action(self, event) def process_IN_CLOSE_NOWRITE(self, event): print "CLOSE_NOWRITE event:", action(self, event) def process_IN_CLOSE_WRITE(self, event): print "CLOSE_WRITE event:", action(self, event) def process_IN_CREATE(self, event): print "CREATE event:", action(self, event) def process_IN_DELETE(self, event): print "DELETE event:", action(self, event) def process_IN_MODIFY(self, event): print "MODIFY event:", action(self, event) def process_IN_OPEN(self, event): print "OPEN event:", action(self, event) #log.setLevel(10) notifier = pyinotify.ThreadedNotifier(wm, EventHandler()) notifier.start() wdd = wm.add_watch(ambient_sensor, mask) wdd time.sleep(5) notifier.stop() Thanks for any hints, suggestions and examples Kind regards Bjoern

  • EAGLContext, EAGLSharegroups, RenderBuffers, FrameBuffers, oh my!

    - by quixoto
    Hi all, I'm trying to wrap my head around the OpenGL object model on iPhone OS. I'm currently rendering into a few different UIViews (build on CAEAGLayers) on the screen. I currently have each of these as using separate EAGLContext, each of which has a color renderbuffer and a framebuffer. I'm rendering similar things in them, and I'd like to share textures between these instances to save memory overhead. My current understanding is that I could use the same setup (some number of contexts, each with a FBO/RBO) but if I spawn the later ones using the EAGLShareGroup of the first one, then I can simply use the texture names (GLuints) from the first one in the later ones. Is this accurate? If this is the case, I guess the followup question is: what's the benefit to having it be a "sharegroup"? Could I just reuse the same context, and attach multiple FBOs/RBOs to that context? I think I'm struggling with the abstraction layer of a sharegroup, which seems to share "objects" (textures and other named things) but not "state" (matrices, enabled/disabled states) which are owned by the context. What's the best way to think of this? Thanks for any enlightenment!

  • Matlab and MrVista

    - by AnnaRaven
    I'm new to MATLAB and mrVista. I'm running Matlab Version 7.8.0.347 (R2009a) 32-bit(win32) from February 12, 2009 OS is Windows 7 Professional I downloaded the most recent MrVista_hourly.zip and extracted it into my C:\Program_Files_(x86)\MATLAB directory. I think I need to run mrvInstall, but when I do, I get the following: EDU>> mrvInstall Checking VISATSOFT installation. Windows, 32-bit, installation Checking and possibly installing .NET framework. This can take several minutes Checking for visualization library (.dll) files. You are missing msvcp70.dll. So, I'm completely lost at this point. Do I just need to download msvcp70.dll from the net? If so, is there a safe place to download it from? If there's some other way I'm supposed to get mrVista to work from MATLAB, instead of mrvInstall, please let me know that. Thanks in advance for your help. EDIT: I've downloaded and installed the dll and still isn't working. I'll go ask on Super User. Thanks for trying to help anyway.

  • How to access device settings on a Sony Ericsson mobile phone?

    - by TheRHCP
    Edited on April 29th Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks. EDIT: It seems that I was totally wrong concerning my phone. This not based on any Symbian OS at all. This is pure Sony Ericsson so the only solution would be to look if Sony Ericsson extended J2ME functionality in their own JVM. I am gonna investigate on this.

  • GUI toolkit for Unicode text app?

    - by wrp
    In developing a tool for processing text in exotic scripts, I'm having trouble choosing a GUI toolkit. The main part of the interface is to be a text editor, not much more elaborate than Notepad, but with its own input method editor. It is to be extensible in a scripting language so that non-programmers can develop their own input methods and display routines. It will be assumed that all files are UTF-8. More elaborate support like regexes is not needed. The main sticking points are: characters beyond the Basic Multilingual Plane right-to-left and bi-directional text extension in a scripting language cross-platform Linux/Windows/OS X My first choice was Tcl/Tk, but it lacks bidi and going beyond the BMP seems dodgy. At the other extreme, I've considered Qt with embedded ECMAScript, but that might be heavier and less malleable than I would like. I'm even thinking about making it browser based, but I'm concerned that the IM for large scripts would be too heavy for client-side processing. I've also looked at a few similar projects in Java, but the quality of the font rendering in SWING has been unacceptable. What are your experiences in handling Unicode with various toolkits? Are there other serious issues I haven't considered? What would you recommend for doing this in the lightest way?

  • Querying a database using Cocoa.

    - by S1syphus
    Hello everybody. Before I start a disclaimer, I should add a little disclaimer, that I am relatively new to Cocoa development and C in general. However I do have a copy of 'Cocoa Programming for Mac OS X 3rd edition' by Aaron Hillegass, which I am working through and using as a base, if anybody has a copy I am using the 'AmaZone' example on page 346 as a template and base. I trying to develop a small client app that takes a search string then displays results from a database accordingly. The database will contain a: list of files, their location, description & creation date, so for the moment the field number and types will remain the same. After looking around on SO, I saw something like: NSURL *myURL = [NSURL URLWithString:@"http://www.myserver.com/results.php"]; NSArray *sqlResults = [[NSArray alloc] initWithContentsOfURL:myURL]; I've worked with php before, so my current thinking after seeing this is create a php script on the server that queries the database, and creates an XML output. And with the XML response, just parse it. Would this be ok? as is there any major pitfalls anybody can see, that I can't. I know there are some database bundles, I've had a look at BaseTen for Postgres, but being relatively new to this, didn't want to get in over my head. Or if anybody else has any other suggestions and ideas, they would be greatly appreciated.

  • Simulating O_NOFOLLOW (2): Is this other approach safe?

    - by Daniel Trebbien
    As a follow-up question to this one, I thought of another approach which builds off of @caf's answer for the case where I want to append to file name and create it if it does not exist. Here is what I came up with: Create a temporary directory with mode 0700 in a system temporary directory on the same filesystem as file name. Create an empty, temporary, regular file (temp_name) in the temporary directory (only serves as placeholder). Open file name for reading only, just to create it if it does not exist. The OS may follow name if it is a symbolic link; I don't care at this point. Make a hard link to name at temp_name (overwriting the placeholder file). If the link call fails, then exit. (Maybe someone has come along and removed the file at name, who knows?) Use lstat on temp_name (now a hard link). If S_ISLNK(lst.st_mode), then exit. open temp_name for writing, append (O_WRONLY | O_APPEND). Write everything out. Close the file descriptor. unlink the hard link. Remove the temporary directory. (All of this, by the way, is for an open source project that I am working on. You can view the source of my implementation of this approach here.) Is this procedure safe against symbolic link attacks? For example, is it possible for a malicious process to ensure that the inode for name represents a regular file for the duration of the lstat check, then make the inode a symbolic link with the temp_name hard link now pointing to the new, symbolic link? I am assuming that a malicious process cannot affect temp_name.

  • Objective-C function dispatch collisions; Or, how to achieve "namespaces"?

    - by fbrereto
    I have an application for Mac OS X that supports plugins that are intended to be loaded at the same time. Some of these plugins are built on top of a Cocoa framework that may receive updates in one plugin but not another. Given Objective-C's current method for function dispatching, any call from any plugin to a given Objective-C routine will go to the same routine every time. That means plugin A can find itself inside plugin B with a trivial Objective-C call! Obviously what we're looking for is for each plugin to interact with its own version of the framework upon which it was built. I have been reading some on Objective-C and this particular need, but haven't found a definitive solution for it yet. Update: My use of the word "framework" above is misleading: the framework is a statically-linked library, built into the plugin(s) that need it. The way Objective-C handles dispatching, however, even these statically linked pieces of disparate code will co-mingle in the Objective-C dispatcher, leading to unintended consequences. Update 2: I'm still a bit fuzzy on the answer provided here, as it doesn't seem to propose a solution as much as an unproven hypothesis.

  • fonts mac vs pc

    - by Kieran
    Hi all hope your having a good day/evening. Simple question, but maybe not so simple to answer. I have an unordered list, which i am using as a menu. The list items are floated right and sized due to an anchor tag inside them with a roll over. The last element is given a specific size to suck up any extra space. See the code snippits bellow. css ul.mainNav { width: 970px; display:block; background:black; clear:both; overflow:hidden;} ul.mainNav li { float: left; height:29px;} ul.mainNav li a { display: block; padding:7px 19px; color:#ffffff; background-color:#000; font-weight:bold; text-decoration:none; font-size:13px; } ul.mainNav li a:hover, ul.mainNav li a.selected { background-color:#ffff00; color:#000; } ul.mainNav li a.last{ text-align:center; padding: 7px 19px; width:58px;} html <ul class="mainNav" id="mainNav"> <li><a href="/Default.aspx">home</a></li> <li><a href="/About/">about</a></li> <li><a href="/News/">news</a></li> <li><a href="/Enter/Registration.aspx">enter SOYA 2010</a></li> <li><a href="/Categories/Film.aspx">categories</a></li> <li><a href="/Mentors/janChapman.aspx">mentors</a></li> <li><a href="/PastWinners/">past winners</a></li> <li><a href="/Awards/">awards nights</a></li> <li><a href="/Support/" class="last">contact</a></li> </ul> It is containted in a <div style="margin:0 auto;">...</div> to center on the menu on screen Now my problem is: On PC; firefox/ Safari /IE /Chrome are all displaying correctly. Take the same code to a Mac; Safari/ firefox are displaying the menu to be too short and the only thing i can point to is that the fonts may be smaller in widths. The width is currently set to 970px. My question is: How can i get it to display at the same widths without specifying exact widths for each list item? Any help would be appreciated. If my structure is wrong or it is just a mac thing that i will never solve(hope not). Cheers, KJ

  • Run a PHP script every second using CLI

    - by Saif Bechan
    Hello, I have a dedicated server running Cent OS with a Parallel PLESK panel. I need to run a php script every second, that updates my database. These is no alternative way timewise, i have checked every method, it needs to be updated every second. I can find my script using the url: http://www.mysite.com/phpfile.php?key=123, and this has to be executed every second. Does anyone have any knowledge at all on doing this, i can not seem to find the answer. I heard about doing it with CLI and putty, but i have no knowledge of this at all. Or can this be done using the PLESK Panel? And can the file be executed locally every second. Like \phpfile.php If someone helps me on answering these question i would really appreciate it. Regards EDIT It has been a few months since i added this question. I ended up using the following code: #!/user/bin/php $start = microtime(true); set_time_limit(60); for (i = 0; i < 59; ++$i) { doMyThings(); time_sleep_until($start + $i + 1); } Thank you for this code guys! My cronjob is set to every minute. I have been running this for some time now in a test environment, and this works out great. It works really supperfast, and i see no increase in CPU nor Memory usage.

  • PHPUnit reporting "Aborted" no matter what tests are run

    - by GrumpyCanuck
    Having a weird problem with PHPUnit. We're using PHPUnit as part of a continuous integration environment, that contains one app written using Zend Framework and one app written using CodeIgniter. Unit tests run just fine under Zend Framework, but whenever I run the tests for CodeIgniter using fooStack's CIUnit bridge, I always get the same problem at the end: PHPUnit 3.4.14 by Sebastian Bergmann. ............... . Time: 1 second, Memory: 7.00Mb OK (16 tests, 14 assertions) Aborted First off, I do not know what those empty spaces between the . means. Secondly, no matter what test I run (all of them or each one separately) I get the same Aborted message at the very end. The tests themselves do not contain any exit or die statements. When I run the same version of PHPUnit on my laptop (running OS-X Snow Leopard and same version of Zend Server Community Edition) I do not get that aborted message. Running PHP 5.3.2 on Ubuntu installed using Zend Server Community Edition. Any help with this would be greatly appreciated.

  • Need help identiying a nasty rootkit in Windows

    - by goofrider
    I have a nasty rootkit that not tools seem to be able to idenity. I know for sure it's a rootkit, but I can figure out which rootkit it is. Here's what I gathered so far: It creates multiple copies of itself in %HOME%\Local Settings\Temp with names like Q.EXE, IAJARZ.exe, etc., and install them as hidden services. These EXE have SysInternals identifiers in them so they're definitely rootkits. It hooked very deep in the system, including file read/write, security policies, registry read/write, and possibly WinSock/TCP/IP. When going to Sophos.com to download their software, the rootkit inject something called Microsoft Ajax Tootkit into the page, which injects code into the email submission form in order to redirect it. (EDIT: I might have panicked. Looks like Sophos does use an AJAZ email form, their form is just broken on Chrome so it looked like a mail form injection attack, the link is http://www.sophos.com/en-us/products/free-tools/virus-removal-tool/download.aspx ) Super-Antispyware found a lot of spyware cookies, in the name of .kaspersky.2o7.net, etc. (just chedk 2o7.net, looks like it's a legit ad company) I tried comparing DNS lookup from the infected systems and from system in other physical locations, no DNS redirections it seems. I used dd to copy the MBR and compared it with the MBR provided by ms-sys package, no differences so it's not infecting MBR. No antivirus or rootkit scanner be able to identify it. Most of them can't even find it. I tried scanning, in-situ (normal mode), in safe mode, and boot to linux live CD. Scanners used: Avast, Sophos anti rootkit, Kasersky TDSSKiller, GMER, RootkitRevealer, and many others. Kaspersky reported some unsigned system files that ought to be signed (e.g. tcpip.sys), and reported a number of MD5 mismatches. But otherwise couldn't identify anything based on signature. When running Sysinternal RootkitRevealer and Sophos AntiRootkit, CPU usage goes up to 100% and gets stucked. The Rootkit is blocking them. When trying running/installing HiJackThis, RootkitRevealer and some other scanners, it tells me system security policy prevent running/installing it. The list of malicious acitivities go on and on. here's a sample of logs from all my scans. In particular, aswSnx.SYS, apnenfno.sys and PROCMON20.SYS has a huge number of hooks. It's hard to tell if the rootkit replaced legit program files like aswSnx.SYS (from Avast) and PROCMON20.SYS (from Sysinternal Process Monitor). I can't find whether apnenfno.sys is from a legit program. Help to identify it is appreciated.

  • Suggestions for entering mobile development -- pure iPhone SDK, Andorid SDK. Mono Touch or Titanium?

    - by Tom Cabanski
    I am entering mobile development. I have been working primarily in .NET since 1.0 came out in beta. Before that, I was mostly a C++ and Delphi guy and still dabble in C++ from time to time. I do web apps quite a bit so I am reasonably proficient with Javascript, JQuery and CSS. I have also done a few Java applications. I started web programming with CGI and live mostly in the ASP.NET MVC world these days. I am trying to decide on which platform/OS and tool to select. I am concerned with the size of the market available for my applications as well as the marketibility of the skills I will pick up. The apps I have in mind would work on both phones and pads. Some aspects of what I have in mind will play better on the bigger screens that will be available on pads. Here are the options I am considering: Apple iPhone/iPad using pure Apple SDK (Objective-C) Apple iPhone/iPad using Mono Touch (C#) Android using pure Android SDK (Java) Multiple platforms using something like Titanium to generate native apps from web technologies (HTML, CSS and Javascript) Multiple platforms using HTML5 web applications that run in the browser (HTML, CSS and Javascript). Which option would you choose? Do you have a different suggestion? What are the pros and cons?

  • How to build a web crawler to find a specific advert, which is in an iframe loaded by Javascript

    - by ZoFreX
    I'm trying to find all instances of an advert on a website. The advert is in an iframe which is loaded by javascript (it doesn't appear at all if javascript is turned off). Detecting the advert itself is extremely simple, both the name of the flash file and the target of the href always contain a certain string. What would be the best "starting point" for achieving this? At the moment I'm considering an Adobe AIR app, which could crawl the site and examine the DOM to find the ad, and would run javascript and load the content of the iframe. The other option I can think of is using Firefox as the platform (using maybe GreaseMonkey or Selenium? I don't really know how to leverage Firefox like this). Does anyone know of anything suitable to build this, or have any suggestions on using Firefox to do it? Extra details: Being CPU intensive isn't really an issue, nor is anything depending on a browser being open. This doesn't need to run on a headless server, it will be running on a powerful desktop box. OS is also not an issue. It would be advantageous if the crawler loaded each page multiple times, as the advert is in rotation. While the crawler does need to execute the javascript and load the content of the iframe, it does not need to be able to display flash files.

  • How to add video into a webpage for mobile web browsers.

    - by payling
    Our company is making a mobile version of our website. We have several product videos we want to show on the mobile version. When I try to use <a href="video.wmv">video</a> I get sound playing but a black screen on my htc incredible android os phone. I'm thinking that the video is playing but in a different browser window. I need it to display all in one window without having to switch to a different window. I tried the html embed tags and get no video or sound at all, from what I've read these tags are not very realiable cross browser. I also just tried the html5 video tags below. I get an icon identifying that it's a video file but it doesn't play. <video src="video.wmv" controls="controls"> your browser does not support the video tag </video> Is there a special format the video file needs to be in? Should I be using the href or embed tags, what other options do I have? If it helps to know, I'm using the mobile doctype on my webpages. Thanks

  • Android Accessing Accelerometer: Returns always 0 as Value

    - by Rotesmofa
    Hello there, i would like to use the accelerometer in an Android Handset for my Application. The data from the sensor will be saved together with a GPS Point, so the Value is only needed when the GPS Point is updated. If i use the attached Code the values is always zero. API Level 8 Permissions: Internet, Fine Location Testing Device: Galaxy S(i9000), Nexus One Any Suggestions? I am stuck at this point. Best regards from Germany, Pascal import android.app.Activity; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.os.Bundle; public class AccelerometerService extends Activity{ AccelerometerData accelerometerData; private SensorManager mSensorManager; private float x,y,z; private class AccelerometerData implements SensorEventListener{ public void onSensorChanged(SensorEvent event) { x = event.values[0]; y = event.values[1]; z = event.values[2]; } public void onAccuracyChanged(Sensor sensor, int accuracy) {} } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE); mSensorManager.registerListener(accelerometerData, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST); } @Override protected void onResume() { super.onResume(); } @Override protected void onStop() { mSensorManager.unregisterListener(accelerometerData); super.onStop(); } public String getSensorString() { return ("X: " + x+"m/s, Y: "+ y +"m/s, Z: "+ z +"m/s" ); } }

  • Time Machine for Windows?

    - by Blub
    Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

  • iPad: Detecting External Keyboard

    - by StuartW
    My app uses a UIAccessoryView to provide additional keyboard functionality (such as forward/backward tabs and arrows keys) for the virtual keyboard, but that causes UIKeyboardDidShowNotification to fire even when a physical keyboard is present (the accessory appears at the bottom of the screen). I'd like to check if a physical keyboard is attached when handling UIKeyboardWillShowNotification, to prevent the accessory view from appearing and to prevent my custom view from scrolling up (to make room for the non-existent virtual keyboard). I've tried examining the UIKeyboardFrameEndUserInfoKey key, but it returns a real size for the virtual keyboard, in spite of nothing being displayed. Is there any way to detect the presence of a physical keyboard to prevent this unwanted behaviour? Hmm, the plot thickens. I tried disabling the input accessory by returning nil from the inputAccessoryView property of the Responder object which triggers the keyboard. That suppresses UIKeyboardWillShowNotification and UIKeyboardDidShowNotification when there is a physical keyboard present, but keeps these notifications when there is no such keyboard. All good so far. Then I tried re-enabling inputAccessoryView only after UIKeyboardWillShowNotification had been received. This only fires when a virtual keyboard is needed, so it should allow me to reintroduce the accessory view in those circumstances. Or so I thought. Unfortunately, it seems the OS doesn't check inputAccessoryView after UIKeyboardWillShowNotification, so it fails to show the accessory view when it is needed :o( That leaves me with two options: Include the input accessory view, giving extra functionality for virtual keyboard users, but lose the ability to detect a physical keyboard and hence not supporting physical devices; or Exclude the input accessory altogether, preventing most users from accessing the extra keys, but allowing the app to work with a physical keyboard. Not a great choice, so I'm still keen to see if anyone else has addressed this problem!

  • Memory problems while code is running (Python, Networkx)

    - by MIN SU PARK
    I made a code for generate a graph with 379613734 edges. But the code couldn't be finished because of memory. It takes about 97% of server memory when it go through 62 million lines. So I killed it. Do you have any idea to solve this problem? My code is like this: import os, sys import time import networkx as nx G = nx.Graph() ptime = time.time() j = 1 for line in open("./US_Health_Links.txt", 'r'): #for line in open("./test_network.txt", 'r'): follower = line.strip().split()[0] followee = line.strip().split()[1] G.add_edge(follower, followee) if j%1000000 == 0: print j*1.0/1000000, "million lines done", time.time() - ptime ptime = time.time() j += 1 DG = G.to_directed() # P = nx.path_graph(DG) Nn_G = G.number_of_nodes() N_CC = nx.number_connected_components(G) LCC = nx.connected_component_subgraphs(G)[0] n_LCC = LCC.nodes() Nn_LCC = LCC.number_of_nodes() inDegree = DG.in_degree() outDegree = DG.out_degree() Density = nx.density(G) # Diameter = nx.diameter(G) # Centrality = nx.betweenness_centrality(PDG, normalized=True, weighted_edges=False) # Clustering = nx.average_clustering(G) print "number of nodes in G\t" + str(Nn_G) + '\n' + "number of CC in G\t" + str(N_CC) + '\n' + "number of nodes in LCC\t" + str(Nn_LCC) + '\n' + "Density of G\t" + str(Density) + '\n' # sys.exit() # j += 1 The edge data is like this: 1000 1001 1000245 1020191 1000 10267352 1000653 10957902 1000 11039092 1000 1118691 10346 11882 1000 1228281 1000 1247041 1000 12965332 121340 13027572 1000 13075072 1000 13183162 1000 13250162 1214 13326292 1000 13452672 1000 13844892 1000 14061830 12340 1406481 1000 14134703 1000 14216951 1000 14254402 12134 14258044 1000 14270791 1000 14278978 12134 14313332 1000 14392970 1000 14441172 1000 14497568 1000 14502775 1000 14595635 1000 14620544 1000 14632615 10234 14680596 1000 14956164 10230 14998341 112000 15132211 1000 15145450 100 15285998 1000 15288974 1000 15300187 1000 1532061 1000 15326300 Lastly, is there anybody who has an experience to analyze Twitter link data? It's quite hard to me to take a directed graph and calculate average/median indegree and outdegree of nodes. Any help or idea?

  • Resizing Images In a Table Using JavaScript

    - by Abluescarab
    Hey, all. I apologize beforehand if none of this makes sense, or if I sound incompetent... I've been making webpages for a while, but don't know any JavaScript. I am trying to make a webpage for a friend, and he requested if I could write some code to resize the images in the page based on the user's screen resolution. I did some research on this question, and it's kind of similar to this, this, and this. Unfortunately, those articles didn't answer my question entirely because none of the methods described worked. Right now, I have a three-column webpage with 10 images in a table in the left sidebar, and when I use percentages for their sizes, they don't resize right between monitors. As such, I'm trying to write a JavaScript function that changes their sizes after detecting the screen resolution. The code is stripped from my post if I put it all, so I'll just say that each image links to a website and uses a separate image to change color when you hover over it. Would I have to address both images to change their sizes correctly? I use a JavaScript function to switch between them. Anyway, I tried both methods in this article and neither worked for me. If it helps, I'm using Google Chrome, but I'm trying to make this page as cross-browser as possible. Here's the code I have so far in my JavaScript function: function resizeImages() { var w = window.width; var h = window.height; var yuk = document.getElementById('yuk').style; var wb = document.getElementById('wb').style; var tf = document.getElementById('tf').style; var lh = document.getElementById('lh').style; var ko = document.getElementById('ko').style; var gz = document.getElementById('gz').style; var fb = document.getElementById('fb').style; var eg = document.getElementById('eg').style; var dl = document.getElementById('dl').style; var da = document.getElementById('da').style; if (w = "800" && h = "600") { } else if (w = "1024" && h = "768") { } else if (w = "1152" && h = "864") { } else if (w = "1280" && h = "720") { } else if (w = "1280" && h = "768") { } else if (w = "1280" && h = "800") { } else if (w = "1280" && h = "960") { } else if (w = "1280" && h = "1024") { } } Yeah, I don't have much in it because I don't know if I'm doing it right yet. Is this a way I can detect the "width" and "height" properties of a window? The "yuk", "wb", etcetera are the images I'm trying to change the size of. To sum it up: I want to resize images based on screen resolution using JavaScript, but my research attempts have been... futile. I'm sorry if that was long-winded, but thanks ahead of time!

  • How to choose light version of databse system

    - by adopilot
    I am starting one POS (Point of sale) project. Targeting system is going to be written in C# .NET 2 WinForms and as main database server We are going to use MS-SQL Server. As we have a lot of POS devices in chain for one store I will love to have backend local data base system on each POS device. Scenario are following: When main server goes down!! POS application should continue working "off-line" with local database, until connection to main server come up again. Now I am in dilemma which local database is going to be most adoptable for me. Here is some notes for helping me point me in right direction: To be Light "My POS devices art usually old and suffering with performances" To be Free "I have a lot of devices and I do not wont additional cost beside main SQL serer" One day Ill love to try all that port on Mono and Linux OS. Here is what I've researched so far: Simple XML "Light but I am afraid of performance, My main table of items is average of 10K records" SQL-Expres "I am afraid that my POS devices is poor with hardware for SQLExpres, and also hard to install on each device and configure" Less known Advantage Database Server have free distribution of offline ADT system. DBF with extended Library,"Respect for good old DBFs but that era is behind Me with clipper and DBFs" MS Access Sqlite "Mostly like for now, but I am afraid how it is going to pair with MS SQL do they have same Data taypes". I know that in this SO is a lot of subjective data, but at least can someone recommended some others lite database system, or things that I shod most take attention before I choice database.
