• Free mp3 merge for Mac OSX

  - by Lilly

  Hi, I need to merge several mp3 tracks into one, I use MAC OS X 10.5. I want to convert all my Harry Potter CDs to my iPod, but not every minute a new track (as it is on the CDs) but chapterwise. Where can I get a free software? Help, please! (I've already tried: Jfuse, but after I had merged a few chapters it said I had to buy it; emicsoft VOB Converter for MAC; File Stitcher; but since they all were shareware, for free they would only let me merge 2 files at once (that would take me days) or half of each file which is useless of course; iTunes advanced settings ("join CD tracks") when importing the CDs, but it would let me only join the complete CD, not chapters...) (Sorry for my English, hope you could understand what I wanted to say)

• Certain SFTP user cannot connect

  - by trobrock

  I have my Ubuntu Server set up so users with the group of sftponly can connect with sftp, but have a shell of /bin/false, and they connect to their home directories. This is working fine with three of the user accounts I have. But I added a new user account today the same way that I added the others and it will not successfully connect. sftp -vvv user@hostname debug1: Next authentication method: password user@hostname's password: debug3: packet_send2: adding 48 (len 73 padlen 7 extra_pad 64) debug2: we sent a password packet, wait for reply debug1: Authentication succeeded (password). debug2: fd 5 setting O_NONBLOCK debug3: fd 6 is O_NONBLOCK debug1: channel 0: new [client-session] debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug1: Requesting [email protected] debug1: Entering interactive session. debug1: channel 0: free: client-session, nchannels 1 debug3: channel 0: status: The following connections are open: #0 client-session (t3 r-1 i0/0 o0/0 fd 5/6 cfd -1) debug3: channel 0: close_fds r 5 w 6 e 7 c -1 debug1: fd 0 clearing O_NONBLOCK debug3: fd 1 is not O_NONBLOCK Connection to hostname closed by remote host.

• OS X Server App ail not accept login credentials

  - by user164113

  I cannot login to the server app and i know for sure all the login info is right. every time i enter my password the name window shakes to tell me it's invalid. I never post unless I'm out of ideas and I need it to be up so I can host my splash page tonight. i've spoken with "certified apple" specialists at some local mac stores and they are stumped too. Something is going on with the apache server, that's all i know for sure. I'll be monitoring this closely so any requests for info, etc. can be filled instantly. Thanks in advance. here's a few things i've noticed: I can ssh successfully into the server address as both root and admin. I've been fussing with the workgroup manager and could use guidance if that's where the problem lies. console shows this message repeatedly (org.apache.httpd[1890]) Exited with code: 1). Much appreciated, harry

• Log - Server kernel: INFO: task httpd:000000 blocked for more than 120 seconds

  - by valter

  Almost everyday my server is crashing due to hight server load, and even restarting apache or mysql can't solve the problem. I need to reboot the server to solve, or it crash again due to the high load. The log system records something like this when it crashes: Aug 11 18:33:53 server kernel: INFO: task httpd:20008 blocked for more than 120 seconds.

But it looks that the solution is just to update the kernel or disk driver, thinks that I don't know how to do. In this url http://bugs.centos.org/view.php?id=4515 a lot o people report similar problems, except the fact that they are not related to httpd like mine. According to one member, one solution would be to add "elevator=noop " to /etc/grub.conf like in this example: title CentOS (2.6.18-238.12.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-238.12.1.el5xen ro root=/dev/VolGroup00/LogVol00 elevator=noop initrd /initrd-2.6.18-238.12.1.el5xen.img Would this really solve the problem? My disk are working in RAID. Can this cause some problem to my server? Is there any other solution?

• OpenLDAP with StartTLS broken on Debian Lenny

  - by mr.zog

  I'm trying to get OpenLDAP on Lenny to work with StartTLS. I have a Fedora 13 machine which I'm using as a client for testing. So far the Fedora client is ignoring the 'host' directive in /etc/ldap.conf when I try to connect using ldapsearch. The client wants to connect to 127.0.0.1:389 even if I specify -H ldaps://server.name on when using ldapsearch. /etc/ldap.conf on the client machine is in mode 444. But even when I try connecting locally from an ssh session, I see errors like this: ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) Someone hit me with a cluebat, plz. Update: you must use ~/.ldaprc for settings such as 'host'. Also, I just used nmap against the ldap server and it showed 636 and 389 in an open state. Here's what prints to screen when I try to connect with, ldapsearch -ZZ –x '(objectclass=*)'+ -d -1 ldap_create ldap_extended_operation_s ldap_extended_operation ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP 192.168.10.41:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 192.168.10.41:636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 ldap_open_defconn: successful ldap_send_server_request ber_scanf fmt ({it) ber: ber_dump: buf=0x9bdbdb8 ptr=0x9bdbdb8 end=0x9bdbdd7 len=31 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ber_scanf fmt ({) ber: ber_dump: buf=0x9bdbdb8 ptr=0x9bdbdbd end=0x9bdbdd7 len=26 0000: 77 18 80 16 31 2e 33 2e 36 2e 31 2e 34 2e 31 2e w...1.3.6.1.4.1. 0010: 31 34 36 36 2e 32 30 30 33 37 1466.20037 ber_flush2: 31 bytes to sd 3 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ldap_write: want=31, written=31 0000: 30 1d 02 01 01 77 18 80 16 31 2e 33 2e 36 2e 31 0....w...1.3.6.1 0010: 2e 34 2e 31 2e 31 34 36 36 2e 32 30 30 33 37 .4.1.1466.20037 ldap_result ld 0x9bd3050 msgid 1 wait4msg ld 0x9bd3050 msgid 1 (infinite timeout) wait4msg continue ld 0x9bd3050 msgid 1 all 1 ** ld 0x9bd3050 Connections: * host: 192.168.10.41 port: 636 (default) refcnt: 2 status: Connected last used: Sun Jun 6 12:54:05 2010 ** ld 0x9bd3050 Outstanding Requests: * msgid 1, origid 1, status InProgress outstanding referrals 0, parent count 0 ld 0x9bd3050 request count 1 (abandoned 0) ** ld 0x9bd3050 Response Queue: Empty ld 0x9bd3050 response count 0 ldap_chkResponseList ld 0x9bd3050 msgid 1 all 1 ldap_chkResponseList returns ld 0x9bd3050 NULL ldap_int_select read1msg: ld 0x9bd3050 msgid 1 all 1 ber_get_next ldap_read: want=8, got=0 ber_get_next failed. ldap_err2string ldap_start_tls: Can't contact LDAP server (-1)

• CNAME to another domain fails on some office networks, why?

  - by crashalpha

  Our domain "aspenfasteners.com" is hosted by Volusion. We have CNAME records "find" and "search" which point to site indexing accounts on www.picosearch.com. These addresses fail on SOME private office networks which have their own DNS. We suspect the problem comes from Volusion's own name servers, n2.volusion.com and n3.volusion.com. Volusion support on problems this technical is non-existant. We have tried an NSLOOKUP on find.aspenfasteners.com with level 2 debugging info, and we got the results below. Is it possible that the local DNS is recursing to Volusion's name servers, and that while Volusion DOES return the canonical name, they do NOT resolve the address? Can anybody with expertise in this sort of stuff PLEASE look at the NSLOOKUP below and tell me if we are right, because Volusion is giving me absolutely NO support on this topic. I need proof of where the problem lies. Thanks VERY much!

• 14.04 LTS Unity no longer boots after last 94 MB update

  - by Harryg123

  I am running 14.04 LTS, Unity, on an HP Pavillion 15, 4GBRAM, 750 GB hdd, I-5 machine, with AMD 8600M graphics card built in. I have disabled the dash and all Ubuntu spyware. I have been faithfully loading all updates as they appear. This morning it asked for a 94 MB update (bringing kernel to .27, I think. Now, I can boot, get to login screen, but it freezes after that. Keyboard doesn't work at that point, but mouse does. I booted into recovery mode, tried to run in generic graphics mode, -- system again froze. I also pressed [esc] during boot, but saw nothing strange; then text disappeared and was replaced by login screen. I am not a hobbyist; this is a production machine and I have a lot of work to do today. Having a standard software update render my machine completely useless... sigh. Perhaps the simplest thing to do would be to revert to the previous configuration. How do I do that? I can boot into recovery mode. But I have no idea how to proceed. TIA for all help. -Harry

• Sneak Preview - New CodePlex UI

  We have been busy the last several months working to improve the overall experience for the CodePlex community. We have been working through some of the top requested items, such as our big announcement last week enabling Git. Something that is not explicitly on the feature request list are requests to update the web site look and user experience.  As Brian Harry mentioned, the Future of CodePlex is Bright, so it is time to start brightening up the place. Goals As with any sizeable change you need to decide the scope of changes you want to tackle. We decided that we would optimize on incremental improvements verses taking months to get a completely new experience released. Our goals with this user experience work is to refresh the look and feel of the site, introduce new visual elements and set up the site for future structural changes. So this is not the end, just the beginning. Early Views I want to set a few expectations first, these screen shots are not final, and we are still working through the content and final element placement. Feedback is always welcome, just take that in mind as you review the images. New CodePlex Home The navigation changed a good bit on the home page and we have moved the search to a more consistent location across the site.   User Profile Users Home Page The goal was to make it easier to find and take action on common tasks such as creating projects. Project Home Issue Tracker   This should give you a taste of where we are going with the new user experience.     As always we love the feedback, either comment below, find us on Twitter @codeplex or @mgroves84, or create or vote up suggestions.

• Blog Rebranding

  I have been spending more and more time on learning as much as I can on Agile Development and also have been fairly immersed in rolling out TFS 2010 in our environment.  I feel like it is time to talk about some of my experiences.  With that, I am rebranding my blog to focus on these topics.  I am going to start with a bunch of blogs on the process I have gone through getting TFS 2010 configured for our development teams. Last week, Brian Harry was in our office and gave a great talk on the improved tools in TFS 2010 and how Microsoft uses the tools internally.  I followed that up with a high-level overview of the improved out of the box process templates and the process to customize them.  I am definitely very excited about the new features in 2010 and hopefully will keep up my motivation to blog about it.  I am writing my first post right now about the process I went through to build a task progress report based on the user story progress report in the MSF for Agile Development template.  Stay tunedDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Using Git with TFS projects

  If you having been following the updates to CodePlex over the last several months you will have noticed that we added support for Git source control. It is important to the CodePlex team to enable developers to use the source control system that supports their development style whether it is distributed version control or centralized version control. There are many projects on CodePlex that are using TFS centralized version control. But we continue to see more and more developers interested in using Git. Last week Brian Harry announced a new open source project called Git-TF. Git-TF is a client side bridge that enabled developer to use Git locally and push to a remote backed by Team Foundation version control. Git-TF also works great for TFS based projects on CodePlex. You may already be familiar with git-tfs. Git-TFS is a similar client side bridge between Git and TFS. Git-TFS works great if you are on Windows since it depends on the TFS .Net client object model. Git-TF adds the ability to use a Git to TFS bridge on multiple platforms since it is written in Java. You can use it on Mac OS X, Linux, and Windows, etc. Since you are connecting to a TFS Server when using Git-TF make sure you use your CodePlex TFS account name: snd\YOUR_USERNAME_cp along with your password. At this point, you will need to be a member of the project to connect using Git-TF. Resources Git-TF Getting Started Guide Download: Git-TF Git-TF Source on CodePlex

• Mysterious dbboon folder with proxy.php file on my godaddy account

  - by Paul

  When doing some web maintenance today, I noticed a strange new folder on my GoDaddy hosting account at the root level named "dbboon", with a single file inside, called proxy.php. It's code is listed below, and seems to be some sort of proxy function. I was kind of troubled because I didn't put it there. I googled all this to learn more, but didn't find anything, except for the proxy file happened to be also stored at pastebin.com: http://pastebin.com/PQsSPbCr I called GoDaddy and they confirmed that it belonged to them, said it was put there by their advanced hosting group for testing purposes but didn't have any more information. I thought this was all really weird: why would they put something in my folder without giving me a heads-up, and why would they need to do something like this? anybody know anything about this? <?php $version = '1.2'; if(isset($_GET['dbboon_version'])) { echo '{"version":"' . $version .

• Fading in/Fade out text in IE

  - by tau

  I had a problem and whipped up a quick solution: fade-in and fade-out a series of quotations. My solution works just as I want it in every browser except any of the IEs. The only problem with the IEs is that the text does not fade in and fade out; the text simply pops into existence. I believe I've run into a similar problem before when trying to dynamically change the filter:alpha(opacity=xx) of an element. Any help is greatly appreciated! <html> <head> <style> .fadetext{ background:green; border:1px solid red; height:50px; width:500px; } .fadetext div{ background:yellow; } </style> <script type="text/javascript"> var CI_common = { C:function(cls,elm){ if(!elm) elm = document; if(document.getElementsByClassName){ return elm.getElementsByClassName(cls); }else{ var t = []; var o = elm.getElementsByTagName("*"); var r = new RegExp("(^|\\s)" + cls + "($|\\s)"); for(var i=0;i<o.length;i++){ if(o[i].className.match(r)) t.push(o[i]); } return t; } }, eventAdd:function(obj,evt,func){ if(obj.addEventListener){ obj.addEventListener(evt,func,false); }else if(obj.attachEvent){ obj["x" + evt + func] = func; obj[evt + func] = function(){ obj["x" + evt + func](window.event); } obj.attachEvent("on" + evt,obj[evt + func]); } } } var CI_fadetext = { init:function(){ var c = CI_common.C("fadetext"); // Simply a getElementsByClassName function for(var i=0;i<c.length;i++){ c[i].style.overflow = "hidden"; var kids = c[i].getElementsByTagName("div"); for(var j=0;j<kids.length;j++){ kids[j].style.display = "none"; kids[j].style.filter = "alpha(opacity=0)"; kids[j].style.opacity = "0"; (function(obj,index,len){ obj.fadetexttimeout = setTimeout(function(){ CI_fadetext.fade(obj,true); obj.fadeininterval = setInterval(function(){ CI_fadetext.fade(obj,true); },5000*len) },5000*index); setTimeout(function(){ CI_fadetext.fade(obj,false); obj.fadeoutinterval = setInterval(function(){ CI_fadetext.fade(obj,false); },5000*len) },5000*index+4400); })(kids[j],j,kids.length); } } }, fade:function(elm,dir){ function fade(start){ start = (dir ? start + 10 : start - 10); elm.style.filter = "alpha(opacity=" + start + ")"; elm.style.opacity = start/100; document.getElementById("output").innerHTML = elm.style.filter; if(start > 100 || start <0){ elm.style.display = (dir ?

• PyML 0.7.2 - How to prevent accuracy from dropping after storing/loading a classifier?

  - by Michael Aaron Safyan

  This is a followup from "Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?". The solution to that question was close, but not quite right, (the SparseDataSet is broken, so attempting to save/load with that dataset container type will fail, no matter what. Also, PyML is inconsistent in terms of whether labels should be numbers or strings... it turns out that the oneAgainstRest function is actually not good enough, because the labels need to be strings and simultaneously convertible to floats, because there are places where it is assumed to be a string and elsewhere converted to float) and so after a great deal of hacking and such I was finally able to figure out a way to save and load my multi-class classifier without it blowing up with an error.... however, although it is no longer giving me an error message, it is still not quite right as the accuracy of the classifier drops significantly when it is saved and then reloaded (so I'm still missing a piece of the puzzle). I am currently using the following custom mutli-class classifier for training, saving, and loading: class SVM(object): def __init__(self,features_or_filename,labels=None,kernel=None): if isinstance(features_or_filename,str): filename=features_or_filename; if labels!=None: raise ValueError,"Labels must be None if loading from a file."; with open(os.path.join(filename,"uniquelabels.list"),"rb") as uniquelabelsfile: self.uniquelabels=sorted(list(set(pickle.load(uniquelabelsfile)))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; self.classifiers=[]; for classidx, classname in enumerate(self.uniquelabels): self.classifiers.append(PyML.classifiers.svm.loadSVM(os.path.join(filename,str(classname)+".pyml.svm"),datasetClass = PyML.VectorDataSet)); else: features=features_or_filename; if labels==None: raise ValueError,"Labels must not be None when training."; self.uniquelabels=sorted(list(set(labels))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; points = [[float(xij) for xij in xi] for xi in features]; self.classifiers=[PyML.SVM(kernel) for label in self.uniquelabels]; for i in xrange(len(self.uniquelabels)): currentlabel=self.uniquelabels[i]; currentlabels=['+1' if k==currentlabel else '-1' for k in labels]; currentdataset=PyML.VectorDataSet(points,L=currentlabels,positiveClass='+1'); self.classifiers[i].train(currentdataset,saveSpace=False); def accuracy(self,pts,labels): logger=logging.getLogger("ml"); correct=0; total=0; classindexes=[self.labeltoindex[label] for label in labels]; h=self.hypotheses(pts); for idx in xrange(len(pts)): if h[idx]==classindexes[idx]: logger.info("RIGHT: Actual \"%s\" == Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])); correct+=1; else: logger.info("WRONG: Actual \"%s\" != Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])) total+=1; return float(correct)/float(total); def prediction(self,pt): h=self.hypothesis(pt); if h!=None: return self.uniquelabels[h]; return h; def predictions(self,pts): h=self.hypotheses(self,pts); return [self.uniquelabels[x] if x!=None else None for x in h]; def hypothesis(self,pt): bestvalue=None; bestclass=None; dataset=PyML.VectorDataSet([pt]); for classidx, classifier in enumerate(self.classifiers): val=classifier.decisionFunc(dataset,0); if (bestvalue==None) or (val>bestvalue): bestvalue=val; bestclass=classidx; return bestclass; def hypotheses(self,pts): bestvalues=[None for pt in pts]; bestclasses=[None for pt in pts]; dataset=PyML.VectorDataSet(pts); for classidx, classifier in enumerate(self.classifiers): for ptidx in xrange(len(pts)): val=classifier.decisionFunc(dataset,ptidx); if (bestvalues[ptidx]==None) or (val>bestvalues[ptidx]): bestvalues[ptidx]=val; bestclasses[ptidx]=classidx; return bestclasses; def save(self,filename): if not os.path.exists(filename): os.makedirs(filename); with open(os.path.join(filename,"uniquelabels.list"),"wb") as uniquelabelsfile: pickle.dump(self.uniquelabels,uniquelabelsfile,pickle.HIGHEST_PROTOCOL); for classidx, classname in enumerate(self.uniquelabels): self.classifiers[classidx].save(os.path.join(filename,str(classname)+".pyml.svm")); I am using the latest version of PyML (0.7.2, although PyML.__version__ is 0.7.0). When I construct the classifier with a training dataset, the reported accuracy is ~0.87. When I then save it and reload it, the accuracy is less than 0.001. So, there is something here that I am clearly not persisting correctly, although what that may be is completely non-obvious to me. Would you happen to know what that is?

• Concurrent Generation of Sequential Keys

  - by GenTiradentes

  I'm working on a project which generates a very large number of sequential text strings, in a very tight loop. My application makes heavy use of SIMD instruction set extensions like SSE and MMX, in other parts of the program, but the key generator is plain C++. The way my key generator works is I have a keyGenerator class, which holds a single char array that stores the current key. To get the next key, there is a function called "incrementKey," which treats the string as a number, adding one to the string, carrying where necessary. Now, the problem is, the keygen is somewhat of a bottleneck. It's fast, but it would be nice if it were faster. One of the biggest problems is that when I'm generating a set of sequential keys to be processed using my SSE2 code, I have to have the entire set stored in an array, which means I have to sequentially generate and copy 12 strings into an array, one by one, like so: char* keys[12]; for(int i = 0; i < 12; i++) { keys[i] = new char[16]; strcmp(keys[i], keygen++); } So how would you efficiently generate these plaintext strings in order? I need some ideas to help move this along. Concurrency would be nice; as my code is right now, each successive key depends on the previous one, which means that the processor can't start work on the next key until the current one has been completely generated. Here is the code relevant to the key generator: KeyGenerator.h class keyGenerator { public: keyGenerator(unsigned long long location, characterSet* charset) : location(location), charset(charset) { for(int i = 0; i < 16; i++) key[i] = 0; charsetStr = charset->getCharsetStr(); integerToKey(); } ~keyGenerator() { } inline void incrementKey() { register size_t keyLength = strlen(key); for(register char* place = key; place; place++) { if(*place == charset->maxChar) { // Overflow, reset char at place *place = charset->minChar; if(!*(place+1)) { // Carry, no space, insert char *(place+1) = charset->minChar; ++keyLength; break; } else { continue; } } else { // Space available, increment char at place if(*place == charset->charSecEnd[0]) *place = charset->charSecBegin[0]; else if(*place == charset->charSecEnd[1]) *place = charset->charSecBegin[1]; (*place)++; break; } } } inline char* operator++() // Pre-increment { incrementKey(); return key; } inline char* operator++(int) // Post-increment { memcpy(postIncrementRetval, key, 16); incrementKey(); return postIncrementRetval; } void integerToKey() { register unsigned long long num = location; if(!num) { key[0] = charsetStr[0]; } else { num++; while(num) { num--; unsigned int remainder = num % charset->length; num /= charset->length; key[strlen(key)] = charsetStr[remainder]; } } } inline unsigned long long keyToInteger() { // TODO return 0; } inline char* getKey() { return key; } private: unsigned long long location; characterSet* charset; std::string charsetStr; char key[16]; // We need a place to store the key for the post increment operation. char postIncrementRetval[16]; }; CharacterSet.h struct characterSet { characterSet() { } characterSet(unsigned int len, int min, int max, int charsec0, int charsec1, int charsec2, int charsec3) { init(length, min, max, charsec0, charsec1, charsec2, charsec3); } void init(unsigned int len, int min, int max, int charsec0, int charsec1, int charsec2, int charsec3) { length = len; minChar = min; maxChar = max; charSecEnd[0] = charsec0; charSecBegin[0] = charsec1; charSecEnd[1] = charsec2; charSecBegin[1] = charsec3; } std::string getCharsetStr() { std::string retval; for(int chr = minChar; chr != maxChar; chr++) { for(int i = 0; i < 2; i++) if(chr == charSecEnd[i]) chr = charSecBegin[i]; retval += chr; } return retval; } int minChar, maxChar; // charSec = character set section int charSecEnd[2], charSecBegin[2]; unsigned int length; };

• How do I use texture-mapping in a simple ray tracer?

  - by fastrack20

  I am attempting to add features to a ray tracer in C++. Namely, I am trying to add texture mapping to the spheres. For simplicity, I am using an array to store the texture data. I obtained the texture data by using a hex editor and copying the correct byte values into an array in my code. This was just for my testing purposes. When the values of this array correspond to an image that is simply red, it appears to work close to what is expected except there is no shading. The bottom right of the image shows what a correct sphere should look like. This sphere's colour using one set colour, not a texture map. Another problem is that when the texture map is of something other than just one colour pixels, it turns white. My test image is a picture of water, and when it maps, it shows only one ring of bluish pixels surrounding the white colour. When this is done, it simply appears as this: Here are a few code snippets: Color getColor(const Object *object,const Ray *ray, float *t) { if (object->materialType == TEXTDIF || object->materialType == TEXTMATTE) { float distance = *t; Point pnt = ray->origin + ray->direction * distance; Point oc = object->center; Vector ve = Point(oc.x,oc.y,oc.z+1) - oc; Normalize(&ve); Vector vn = Point(oc.x,oc.y+1,oc.z) - oc; Normalize(&vn); Vector vp = pnt - oc; Normalize(&vp); double phi = acos(-vn.dot(vp)); float v = phi / M_PI; float u; float num1 = (float)acos(vp.dot(ve)); float num = (num1 /(float) sin(phi)); float theta = num /(float) (2 * M_PI); if (theta < 0 || theta == NAN) {theta = 0;} if (vn.cross(ve).dot(vp) > 0) { u = theta; } else { u = 1 - theta; } int x = (u * IMAGE_WIDTH) -1; int y = (v * IMAGE_WIDTH) -1; int p = (y * IMAGE_WIDTH + x)*3; return Color(TEXT_DATA[p+2],TEXT_DATA[p+1],TEXT_DATA[p]); } else { return object->color; } }; I call the colour code here in Trace: if (object->materialType == MATTE) return getColor(object, ray, &t); Ray shadowRay; int isInShadow = 0; shadowRay.origin.x = pHit.x + nHit.x * bias; shadowRay.origin.y = pHit.y + nHit.y * bias; shadowRay.origin.z = pHit.z + nHit.z * bias; shadowRay.direction = light->object->center - pHit; float len = shadowRay.direction.length(); Normalize(&shadowRay.direction); float LdotN = shadowRay.direction.dot(nHit); if (LdotN < 0) return 0; Color lightColor = light->object->color; for (int k = 0; k < numObjects; k++) { if (Intersect(objects[k], &shadowRay, &t) && !objects[k]->isLight) { if (objects[k]->materialType == GLASS) lightColor *= getColor(objects[k], &shadowRay, &t); // attenuate light color by glass color else isInShadow = 1; break; } } lightColor *= 1.f/(len*len); return (isInShadow) ? 0 : getColor(object, &shadowRay, &t) * lightColor * LdotN; } I left out the rest of the code as to not bog down the post, but it can be seen here. Any help is greatly appreciated. The only portion not included in the code, is where I define the texture data, which as I said, is simply taken straight from a bitmap file of the above image. Thanks.

• Exception - Illegal Block size during decryption(Android)

  - by Vamsi

  I am writing an application which encrypts and decrypts the user notes based on the user set password. i used the following algorithms for encryption/decryption 1. PBEWithSHA256And256BitAES-CBC-BC 2. PBEWithMD5And128BitAES-CBC-OpenSSL e_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC); d_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC); e_Cipher.init() d_Cipher.init() encryption is working well, but when trying to decrypt it gives Exception - Illegal Block size after encryption i am converting the cipherText to HEX and storing it in a sqlite database. i am retrieving correct values from the sqlite database during decyption but when calling d_Cipher.dofinal() it throws the Exception. I thought i missed to specify the padding and tried to check what are the other available cipher algorithms but i was unable to found. so request you to please give the some knowledge on what are the cipher algorithms and padding that are supported by Android? if the algorithm which i used can be used for padding, how should i specify the padding mechanism? I am pretty new to Encryption so tried a couple of algorithms which are available in BouncyCastle.java but unsuccessful. As requested here is the code public class CryptoHelper { private static final String TAG = "CryptoHelper"; //private static final String PBEWithSHA256And256BitAES = "PBEWithSHA256And256BitAES-CBC-BC"; //private static final String PBEWithSHA256And256BitAES = "PBEWithMD5And128BitAES-CBC-OpenSSL"; private static final String PBEWithSHA256And256BitAES = "PBEWithMD5And128BitAES-CBC-OpenSSLPBEWITHSHA1AND3-KEYTRIPLEDES-CB"; private static final String randomAlgorithm = "SHA1PRNG"; public static final int SALT_LENGTH = 8; public static final int SALT_GEN_ITER_COUNT = 20; private final static String HEX = "0123456789ABCDEF"; private Cipher e_Cipher; private Cipher d_Cipher; private SecretKey secretKey; private byte salt[]; public CryptoHelper(String password) throws InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException, InvalidAlgorithmParameterException, InvalidKeySpecException { char[] cPassword = password.toCharArray(); PBEKeySpec pbeKeySpec = new PBEKeySpec(cPassword); PBEParameterSpec pbeParamSpec = new PBEParameterSpec(salt, SALT_GEN_ITER_COUNT); SecretKeyFactory keyFac = SecretKeyFactory.getInstance(PBEWithSHA256And256BitAES); secretKey = keyFac.generateSecret(pbeKeySpec); SecureRandom saltGen = SecureRandom.getInstance(randomAlgorithm); this.salt = new byte[SALT_LENGTH]; saltGen.nextBytes(this.salt); e_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES); d_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES); e_Cipher.init(Cipher.ENCRYPT_MODE, secretKey, pbeParamSpec); d_Cipher.init(Cipher.DECRYPT_MODE, secretKey, pbeParamSpec); } public String encrypt(String cleartext) throws IllegalBlockSizeException, BadPaddingException { byte[] encrypted = e_Cipher.doFinal(cleartext.getBytes()); return convertByteArrayToHex(encrypted); } public String decrypt(String cipherString) throws IllegalBlockSizeException { byte[] plainText = decrypt(convertStringtobyte(cipherString)); return(new String(plainText)); } public byte[] decrypt(byte[] ciphertext) throws IllegalBlockSizeException { byte[] retVal = {(byte)0x00}; try { retVal = d_Cipher.doFinal(ciphertext); } catch (BadPaddingException e) { Log.e(TAG, e.toString()); } return retVal; } public String convertByteArrayToHex(byte[] buf) { if (buf == null) return ""; StringBuffer result = new StringBuffer(2*buf.length); for (int i = 0; i < buf.length; i++) { appendHex(result, buf[i]); } return result.toString(); } private static void appendHex(StringBuffer sb, byte b) { sb.append(HEX.charAt((b>>4)&0x0f)).append(HEX.charAt(b&0x0f)); } private static byte[] convertStringtobyte(String hexString) { int len = hexString.length()/2; byte[] result = new byte[len]; for (int i = 0; i < len; i++) { result[i] = Integer.valueOf(hexString.substring(2*i, 2*i+2), 16).byteValue(); } return result; } public byte[] getSalt() { return salt; } public SecretKey getSecretKey() { return secretKey; } public static SecretKey createSecretKey(char[] password) throws NoSuchAlgorithmException, InvalidKeySpecException { PBEKeySpec pbeKeySpec = new PBEKeySpec(password); SecretKeyFactory keyFac = SecretKeyFactory.getInstance(PBEWithSHA256And256BitAES); return keyFac.generateSecret(pbeKeySpec); } } I will call mCryptoHelper.decrypt(String str) then this results in Illegal block size exception My Env: Android 1.6 on Eclipse
