  • is it possible to extract certain strings based off a predefined white-space count?

    - by s2xi
    So after several Advil's I think I need help I am trying to make a script that lets the user upload a .txt file, the file will look like this as an example EXT. DUNKIN' DONUTS - DAY Police vehicles remain in the parking lot. The determined female reporter from the courthouse steps, MELINDA FUENTES (32), interviews Comandante Chitt, who holds a napkin to his jaw, like he cut himself shaving. MELINDA < Comandante Chitt, how does it feel to get shot in the face? > COMANDANTE CHITT < Not too different than getting shot in the arm or leg. > MELINDA < Tell us what happened. > COMANDANTE CHITT < I parked my car. (indicates assault vehicle in donut shop) He aimed his weapon at my head. I fired seven shots. He stopped aiming his weapon at my head. > Melinda waits for more, but Chitt turns and walks away into the roped-off crime scene. Melinda is confused for a second, then resumes smiling. MELINDA < And there you have it... A man of few words. > Ok, so based off of this what I want to do is this: The PHP script looks at the file and counts 35 white spaces, since all files will have the same layout and never differ in white spaces I chose this as the best way to go. for every 35 white spaces extract character 36 until the end of line. Then tally up $character++ so in the end the output would look like ----------------------------------- It looks like you have 2 characters in your script Melinda Commandante Chitt ----------------------------------- using PHP to select distinct names, and use the strtolower() to lower case the strings and ucfirst() to make the first letter upper-case thats my project, I'm at the stage where I'm going crazy trying to figure out how to count white-spaces and everything after that white space until the first white-space after the word IS a character name

  • Java "compare cannot be resolved to a type" error

    - by King Triumph
    I'm getting a strange error when attempting to use a comparator with a binary search on an array. The error states that "compareArtist cannot be resolved to a type" and is thrown by Eclipse on this code: Comparator<Song> compare = new Song.compareArtist(); I've done some searching and found references to a possible bug with Eclipse, although I have tried the code on a different computer and the error persists. I've also found similar issues regarding the capitalization of the compare method, in this case compareArtist. I've seen examples where the first word in the method name is capitalized, although it was my understanding that method names are traditionally started with a lower case letter. I have experimented with changing the capitalization but nothing has changed. I have also found references to this error if the class doesn't import the correct package. I have imported java.util in both classes in question, which to my knowledge allows the use of the Comparator. I've experimented with writing the compareArtist method within the class that has the binary search call as well as in the "Song" class, which according to my homework assignment is where it should be. I've changed the constructor accordingly and the issue persists. Lastly, I've attempted to override the Comparator compare method by implementing Comparator in the Song class and creating my own method called "compare". This returns the same error. I've only moved to calling the comparator method something different than "compare" after finding several examples that do the same. Here is the relevant code for the class that calls the binary search that uses the comparator. This code also has a local version of the compareArtist method. While it is not being called currently, the code for this method is the same as the in the class Song, where I am trying to call it from. Thanks for any advice and insight. import java.io.*; import java.util.*; public class SearchByArtistPrefix { private Song[] songs; // keep a direct reference to the song array private Song[] searchResults; // holds the results of the search private ArrayList<Song> searchList = new ArrayList<Song>(); // hold results of search while being populated. Converted to searchResults array. public SearchByArtistPrefix(SongCollection sc) { songs = sc.getAllSongs(); } public int compareArtist (Song firstSong, Song secondSong) { return firstSong.getArtist().compareTo(secondSong.getArtist()); } public Song[] search(String artistPrefix) { String artistInput = artistPrefix; int searchLength = artistInput.length(); Song searchSong = new Song(artistInput, "", ""); Comparator<Song> compare = new Song.compareArtist(); int search = Arrays.binarySearch(songs, searchSong, compare);

  • Zaypay alternatives for payments using call or sms

    - by JohannesH
    We are currently trying to implement a payment provider in zaypay for paying for services using sms or by calling a number. We already have google checkout and paypal working for regular payments but zaypay is rather inflexible, poorly documented and a pain to setup when you have hundreds of products with varying prices. So my question is, do you know of any other european payment providers that take sms and call payments? As a response to Roberts answer/question Hi Robert, I must say that the Zaypay solution is the best and only I've seen thus far regarding phoned payments. However, since its now 2 months ago I finished the implementation of our custom Zaypay UI I can't remember much of the the details of the problems we were having. I'll try to give a brief of them anyways the best I can. First of all I would like to see a redirection type scenario for payalogues. From what I remember you guys are using the JS framework "Prototype" which doesn't play nice with jQuery which we are using so we weren't able to use the popup-type scenario supported by payalogues. Furthermore when implementing our custom interface I remember a lot of missing translations, like words that were codes instead of a word or a phrase. This meant we ended up writing/translating all the messages we needed ourselves. Also, another point of annoyance was the setup of prices and items. I wish we could just send in the order items/prices as a part of the interface like you can in Google Checkout or PayPal (not that they're flawless either), instead of having to define ALL the items you will ever sell through your admin interface beforehand. As far as I can remember it is virtually impossible to use Zaypay for a multi-item order in its current form. Finally there are, as far as I can tell, some security issues that you have to think about when you implement a custom solution... especially a ajax driven one. As I said in my original post you do mention this in the documentation but I believe the documentation wasn't that comprehensive regarding security issues. Again I wish I could give more details but the code & client is long since gone, so I can't look up the comments I wrote. Sorry! Oh yeah, the general API documentation weren't exactly comprehensive and 100% correct either. Again, I don't want to advice people against using Zaypay, I just want to advice that they should try it out first on a realistic prototype and think about their implementation before releasing to production. Maybe its just me who misunderstood a lot of things but I generally had a difficult time using your framework and I was left with a feeling that the API was very new and not thought through from the beginning.

  • :contains for multiple words

    - by Emin
    I am using the following jQuery var etag='kate' if (etag.length > 0) { $('div').each(function () { $(this).find('ul:not(:contains(' + etag + '))').hide(); $(this).find('ul:contains(' + etag + ')').show(); }); }? towards the following HTML <div id="2"> <ul> <li>john</li> <li>jack</li> </ul> <ul> <li>kate</li> <li>clair</li> </ul> <ul> <li>hugo</li> <li>desmond</li> </ul> <ul> <li>said</li> <li>jacob</li> </ul> </div> <div id="3"> <ul> <li>jacob</li> <li>me</li> </ul> <ul> <li>desmond</li> <li>george</li> </ul> <ul> <li>allen</li> <li>kate</li> </ul> <ul> <li>salkldf</li> <li>3kl44</li> </ul> </div> basically, as long as etag has one word, the code works perfectly and hides those elements who do not contain etag. My problem is, when etag is multiple words (and I don't have control over it. Its coming from a database and could be combination of multiple words seperated with space char) then the code does not work.. is there any way to achieve this?

  • Share a "deep link" from a Windows 8/WinRT application

    - by Dave Parker
    I have searched using many different terms and phrases, and waded through many pages of results, but I have (remarkably) not seen anyone else addressing, even asking, about, this issue. So here goes... Ultimate Goal: Allow a user viewing a content-based page (may contain both text and images) within a Windows Store app to share that content with someone else. Description I am working on taking a fair amount of content and making it available for browsing/navigating as a Windows 8/WinRT/Windows Store (we need a consistent name here) application. One of the desired features is to take advantage of the Share Charm, such that someone viewing a page could share that page with someone else. The ideal behavior is for the application to implement the Share Source contract which would share an email message that contained some explanatory text, a link to get the app from the Windows Store, and a "deep link" into the shared page in the application. Solutions Considered We had originally looked at just generating a PDF representation of the page, but there are very few external libraries that would work under WinRT, and having to include externally licensed code would be problematic as well. Writing our own PDF generation code would out of scope. We have also considered generating a Word document or PowerPoint slide using OpenXML, but again, we run up against the limitaions of WinRT. In this case, it is highly unlikely the OpenXML SDK is useable in a WinRT application. Another thought was to pre-generate all of the pages as .pdf files, store them as resources, and when the Share Charm is invoked, share the .pdf file associated with the current page. The problem here is the application will have at least 150 content pages, and depending on how we break the content down, up to over 600. This would likely cause serious bloat. Where We Are At Thus we have come to sharing URIs. From what I can tell, though, the "deep linking" feature is only intended for use on Secondary Tiles tied to your application. Another avenue I considered was registering a protocol like, "my-special-app:" with the OS and having it fire up the application but that would require HKCR registry access, which is outside the WinRT sandbox. If it matters, we are leaning towards an HTML/JS application, rather than XAML/C#, because the converted content will all be in HTML and the WebView control in WinRT is fairly limited. This decision is not yet final, though. Conclusion So, is this possible, and if so, how would it be done or where can I find documentation on it? Thanks, Dave Parker

  • Prevent SQL Injection in Dynamic column names

    - by Mr Shoubs
    I can't get away without writing some dynamic sql conditions in a part of my system (using Postgres). My question is how best to avoid SQL Injection with the method I am currently using. EDIT (Reasoning): There are many of columns in a number of tables (a number which grows (only) and is maintained elsewhere). I need a method of allowing the user to decide which (predefined) column they want to query (and if necessary apply string functions to). The query itself is far too complex for the user to write themselves, nor do they have access to the db. There are 1000's of users with varying requirements and I need to remain as flexible as possible - I shouldn't have to revisit the code unless the main query needs to change - Also, there is no way of knowing what conditions the user will need to use. I have objects (received via web service) that generates a condition (the generation method is below - it isn't perfect yet) for some large sql queries. The _FieldName is user editable (parameter name was, but it didn't need to be) and I am worried it could be an attack vector. I put double quotes (see quoted identifier) around the field name in an attempt to sanitize the string, this way it can never be a key word. I could also look up the field name against a list of fields, but it would be difficult to maintain on a timely basis. Unfortunately the user must enter the condition criteria, I am sure there must be more I can add to the sanatize method? and does quoting the column name make it safe? (my limited testing seems to think so). an example built condition would be "AND upper(brandloaded.make) like 'O%' and upper(brandloaded.make) not like 'OTHERBRAND'" ... Any help or suggestions are appreciated. Public Function GetCondition() As String Dim sb As New Text.StringBuilder 'put quote around the table name in an attempt to prevent some sql injection 'http://www.postgresql.org/docs/8.2/static/sql-syntax-lexical.html sb.AppendFormat(" {0} ""{1}"" ", _LogicOperator.ToString, _FieldName) Select Case _ConditionOperator Case ConditionOperatorOptions.Equals sb.Append(" = ") ... End Select sb.AppendFormat(" {0} ", Me.UniqueParameterName) 'for parameter Return Me.Sanitize(sb) End Function Private Function Sanitize(ByVal sb As Text.StringBuilder) As String 'compare against a similar blacklist mentioned here: http://forums.asp.net/t/1254125.aspx sb.Replace(";", "") sb.Replace("'", "") sb.Replace("\", "") sb.Replace(Chr(8), "") Return sb.ToString End Function Public ReadOnly Property UniqueParameterName() As String Get Return String.Concat(":" _UniqueIdentifier) End Get End Property

  • Direct show video renderers suck?

    - by Daniel
    So I've been looking into the world of media playback for windows and I've started making a C# Media Player using DirectShow. I started off using the VRM-7 windowed video renderer and it was brilliant except it had a couple of small problems (multi monitors, fullscreen). But after some research I found that it's deprecated and I should be using VRM9. So I changed it to use VRM9 windowless then found out that was an old post rofl _< so finally I'm using Vista/Win7 (or XP .net 3) Enhanced Video Renderer (EVR) which is apparently the most up to date Microsoft video renderer and has all the flashy performance/quality things added to it. (tbh I haven't noticed any difference but maybe I need a blue-ray or HQ video to notice it). With using EVR everything is working fine except resizing the video. Its really laggy/choppy/teary and problem something to do with its frame queueing mechanism. To demonstrate my problem open up windows media player classic. View - Options - Playback - output Chose the "EVR" DirectShow Video renderer Now restart wmp class and play a video, while it's playing click and drag a corner to resize it. You'll notice its horribly laggy. This is the exact same problem i am having. But if you chose "EVR Custom Pres. *" or EVR Sync *" resizing works beautifully! So i tried googling around for anything about EVR resizing issues and how to fix it but i couldn't believe how little i could find. I'm guessing "Custom Pres." stands for "Custom Presenter" which sounds like they made their own. Also you'll notice on the right hand size when you swap between EVR and the other EVR's the Resizer drop down on the right greys out. So basically I wan't to know how I can fix this retarded resizing problem and is there any decent documentation out there? There is a fair bit for VMR7/9 but not much for EVR. I downloaded the DirectX SDK which apparently has samples but it was a waste of 500mb of bandwidth as it had nothing relevant. Perhaps there is some way to force it not queueing up frames if that is the problem? If you want code say the word and I'll paste some in. But it's really quite simple and nothing much happens, i'm convinced it's a problem with the EVR renderer. EDIT: Oh and one other thing, what does VLC use? If you go into vlc options and change the renderer to anything but default, they all suck. So is it using VMR7? Or its own?

  • Intrinsics program (SSE) - g++ - help needed

    - by Sriram
    Hi all, This is the first time I am posting a question on stackoverflow, so please try and overlook any errors I may have made in formatting my question/code. But please do point the same out to me so I may be more careful. I was trying to write some simple intrinsics routines for the addition of two 128-bit (containing 4 float variables) numbers. I found some code on the net and was trying to get it to run on my system. The code is as follows: //this is a sample Intrinsics program to add two vectors. #include <iostream> #include <iomanip> #include <xmmintrin.h> #include <stdio.h> using namespace std; struct vector4 { float x, y, z, w; }; //functions to operate on them. vector4 set_vector(float x, float y, float z, float w = 0) { vector4 temp; temp.x = x; temp.y = y; temp.z = z; temp.w = w; return temp; } void print_vector(const vector4& v) { cout << " This is the contents of vector: " << endl; cout << " > vector.x = " << v.x << endl; cout << " vector.y = " << v.y << endl; cout << " vector.z = " << v.z << endl; cout << " vector.w = " << v.w << endl; } vector4 sse_vector4_add(const vector4&a, const vector4& b) { vector4 result; asm volatile ( "movl $a, %eax" //move operands into registers. "\n\tmovl $b, %ebx" "\n\tmovups (%eax), xmm0" //move register contents into SSE registers. "\n\tmovups (%ebx), xmm1" "\n\taddps xmm0, xmm1" //add the elements. addps operates on single-precision vectors. "\n\t movups xmm0, result" //move result into vector4 type data. ); return result; } int main() { vector4 a, b, result; a = set_vector(1.1, 2.1, 3.2, 4.5); b = set_vector(2.2, 4.2, 5.6); result = sse_vector4_add(a, b); print_vector(a); print_vector(b); print_vector(result); return 0; } The g++ parameters I use are: g++ -Wall -pedantic -g -march=i386 -msse intrinsics_SSE_example.C -o h The errors I get are as follows: intrinsics_SSE_example.C: Assembler messages: intrinsics_SSE_example.C:45: Error: too many memory references for movups intrinsics_SSE_example.C:46: Error: too many memory references for movups intrinsics_SSE_example.C:47: Error: too many memory references for addps intrinsics_SSE_example.C:48: Error: too many memory references for movups I have spent a lot of time on trying to debug these errors, googled them and so on. I am a complete noob to Intrinsics and so may have overlooked some important things. Any help is appreciated, Thanks, Sriram.

  • Parsing xml file that comes in as one object per line

    - by Casey
    I haven't been here in so long, I forgot my prior account! Anyways, I am working on parsing an xml document that comes in ugly. It is for banking statements. Each line is a <statement>all tags</statement>. Now, what I need to do is read this file in, and parse the XML document at the same time, while formatting it more human readable too. Point beeing, Original input looks like this: <statement><accountHeader><fiAddress></fiAddress><accountNumber></accountNumber><startDate>20140101</startDate><endDate>20140228</endDate><statementGroup>1</statementGroup><sortOption>0</sortOption><memberBranchCode>1</memberBranchCode><memberName></memberName><jointOwner1Name></jointOwner1Name><jointOwner2Name></jointOwner2Name></summary></statement> <statement><accountHeader><fiAddress></fiAddress><accountNumber></accountNumber><startDate>20140101</startDate><endDate>20140228</endDate><statementGroup>1</statementGroup><sortOption>0</sortOption><memberBranchCode>1</memberBranchCode><memberName></memberName><jointOwner1Name></jointOwner1Name><jointOwner2Name></jointOwner2Name></summary></statement> <statement><accountHeader><fiAddress></fiAddress><accountNumber></accountNumber><startDate>20140101</startDate><endDate>20140228</endDate><statementGroup>1</statementGroup><sortOption>0</sortOption><memberBranchCode>1</memberBranchCode><memberName></memberName><jointOwner1Name></jointOwner1Name><jointOwner2Name></jointOwner2Name></summary></statement> I need the final output to be as follows: <statement> <name></name> <address></address> </statement> This is fine and dandy. I am using the following "very slow considering 5.1 million lines, 254k data file, and about 60k statements takes around 8 minutes". foreach(String item in lines) { XElement xElement = XElement.Parse(item); sr.WriteLine(xElement.ToString().Trim()); } Then when the file is formatted this is what sucks. I need to check every single tag in transaction elements, and if a tag is missing that could be there, I have to fill it in. Our designer software will default prior values in if a tag is possible, and the current objects does not have. It defaults in the value of a prior one that was not Null. "I know, and they swear up and down it is not a bug... ok?" So, that is also taking about 5 to 10 minutes. I need to break all this down, and find a faster method for working with the initial XML. This is a preprocess action, and cannot take that long if not necessary. It just seems redundant. Is there a better way to parse the XML, or is this the best I can do? I parse the XML, write to a temp file, and then read that file in, to the output file inserting the missing tags. 2 IO runs for one process. Yuck.

  • How do you use technology to memorize set of terms?

    - by user49767
    Always there are few set of items needs to be memorized in short span of time. Here are my following cases. 1) My Job requires some set of items needs to be memorized. 2) I am a developer who has to learn 150+ tags within next 3 days. 3) Fix developer/support has to remember minimum of 125+ tags (set of possible values). 4) It is better if team's SQL developer knows all the table and columns in my database. 5) When guys join new department or job. Memorizing few related items will definitely gives some benefit. Most of the cases, I suggest people to understand the domain better and nothing wrong in using google (but remember correct search-word). But recently I came across a junior developer who took lot of effort in memorizing set of things (150+ table structures, fix protocol tags, almost 300+ configuration items from property file) and was very very successful in his job and was swift in responding for support queries. Needless to say he is smart worker too (not a dumb guy). When I try to recollect some of the successful employees I met, they were so good in remembering entire schema and they did in short span of time. But I don't argue that memorizing alone gives success, but it greatly helps when situation demands. Here my question is, I am not good at remembering things, but it shouldn't be lame excuse. Hence I am evaluating using technolgies better to memorize set of items. Not very much interested in memory techniques (mnemoninc, photography memory, etc..). Even I have recorded 100+ items and listen to that whenever I found free time, defintely there were some fruitful result. Now I need your suggestion about what are all the ways to exploit technology to memorize. There could be so many reason why guys remember a subject (passionate, essential, author, creator, responsbile). Not interested in dissecting why guys remeber. Rather much interested in using ways, and techniques (cheat sheet...) to remember a set of itmes. Note : I appreciate, encourage people who could rephrase my question better. Note : I have kept couple of cheat-sheet close to my monitor, honestly it did not help me :).

  • C# - calling ext. DLL function containing Delphi "variant record" parameter

    - by CaldonCZE
    Hello, In external (Delphi-created) DLL I've got the following function that I need to call from C# application. function ReadMsg(handle: longword; var Msg: TRxMsg): longword; stdcall; external 'MyDll.dll' name 'ReadMsg'; The "TRxMsg" type is variant record, defined as follows: TRxMsg = record case TypeMsg: byte of 1: (accept, mask: longword); 2: (SN: string[6]); 3: (rx_rate, tx_rate: word); 4: (rx_status, tx_status, ctl0, ctl1, rflg: byte); end; In order to call the function from C#, I declared auxiliary structure "my9Bytes" containing array of bytes and defined that it should be marshalled as 9 bytes long array (which is exactly the size of the Delphi record). private struct my9Bytes { [MarshalAs(UnmanagedType.ByValArray, ArraySubType = UnmanagedType.U1, SizeConst = 9)] public byte[] data; } Then I declared the imported "ReadMsg" function, using the "my9bytes" struct. [DllImport("MyDll.dll")] private static extern uint ReadMsg(uint handle, ref my9Bytes myMsg); I can call the function with no problem... Then I need to create structure corresponding to the original "TRxMsg" variant record and convert my auxiliary "myMsg" array into this structure. I don't know any C# equivalent of Delphi variant array, so I used inheritance and created the following classes. public abstract class TRxMsg { public byte typeMsg; } public class TRxMsgAcceptMask:TRxMsg { public uint accept, mask; //... } public class TRxMsgSN:TRxMsg { public string SN; //... } public class TRxMsgMRate:TRxMsg { public ushort rx_rate, tx_rate; //... } public class TRxMsgStatus:TRxMsg { public byte rx_status, tx_status, ctl0, ctl1, rflg; //... } Finally I create the appropriate object and initialize it with values manually converted from "myMsg" array (I used BitConverter for this). This does work fine, this solution seems to me a little too complicated, and that it should be possible to do this somehow more directly, without the auxiliary "my9bytes" structures or the inheritance and manual converting of individual values. So I'd like to ask you for a suggestions for the best way to do this. Thanks a lot!

  • How can you make an emacs macro wait for cscope query results?

    - by Sudhanshu
    I am trying to write a macro which calls cscope-find-functions-calling-this-function on each and every tag in a file displayed in the *Tags List* buffer (created by list-tags command). This should create a buffer which contains list of all functions calling a set of functions defined in a certain file. This is the sequence of keystrokes: 1. <f11> ;; cscope-find-functions-calling-this-function 2. RET ;; newline [shows results of cscope in a split window] 3. C-x C-p ;; mark-page 4. C-x C-x ;; icicle-exchange-point-and-mark 5. <up> ;; previous-line 6. <end> ;; end-of-line [region to copy has been marked] 7. <f7> ;; append-results-to-buffer 8. C-x ESC O ;; [move back to split window on the right] 9. C-x b ;; icicle-buffer [Switch back to *Tags List* buffer] 10. *Tags ;; self-insert-command * 5 11. SPC ;; self-insert-command 12. List* ;; self-insert-command * 5 13. RET ;; newline 14 . <down> ;; next-line [Position point on next tag in the list] Problem: I get no results in the buffer, and I found out that's because Step 3-7 execute even before cscope prints the results of query made on Steps 1-2. I can insert a pause in the macro by using C-x q, but I'd rather like the macro to wait after Step 2, until cscope has returned with the results and only then continue further. I suspect this is not possible through a macro, maybe a LISP function... I'm not a lisp expert myself. Can someone please help? Thanks! Details: I have Icicles installed so by default I get word at point in current buffer as input in minibuffer. F11 is bound to cscope-find-functions-calling-this-function windmove is installed and C-x (C-x ESC o - as shown below) takes you to the right window. F7 is bound to append-results-to-buffer which is defined as: (defun append-results-to-buffer () (interactive) (append-to-buffer (get-buffer-create "c1") (point) (mark))) This function just appends the currently marked region to a buffer named "c1".

  • SQLAlchemy unsupported type error - and table design issues?

    - by Az
    Hi there, back again with some more SQLAlchemy shenanigans. Let me step through this. My table is now set up as so: engine = create_engine('sqlite:///:memory:', echo=False) metadata = MetaData() students_table = Table('studs', metadata, Column('sid', Integer, primary_key=True), Column('name', String), Column('preferences', Integer), Column('allocated_rank', Integer), Column('allocated_project', Integer) ) metadata.create_all(engine) mapper(Student, students_table) Fairly simple, and for the most part I've been enjoying the ability to query almost any bit of information I want provided I avoid the error cases below. The class it is mapped from is: class Student(object): def __init__(self, sid, name): self.sid = sid self.name = name self.preferences = collections.defaultdict(set) self.allocated_project = None self.allocated_rank = 0 def __repr__(self): return str(self) def __str__(self): return "%s %s" %(self.sid, self.name) Explanation: preferences is basically a set of all the projects the student would prefer to be assigned. When the allocation algorithm kicks in, a student's allocated_project emerges from this preference set. Now if I try to do this: for student in students.itervalues(): session.add(student) session.commit() It throws two errors, one for the allocated_project column (seen below) and a similar error for the preferences column: sqlalchemy.exc.InterfaceError: (InterfaceError) Error binding parameter 4 - probably unsupported type. u'INSERT INTO studs (sid, name, allocated_rank, allocated_project) VALUES (?, ?, ?, ?, ?, ?, ?)' [1101, 'Muffett,M.', 1, 888 Human-spider relationships (Supervisor id: 123)] If I go back into my code I find that, when I'm copying the preferences from the given text files, it actually refers to the Project class which is mapped to a dictionary, using the unique project id's (pid) as keys. Thus, as I iterate through each student via their rank and to the preferences set, it adds not a project id, but the reference to the project id from the projects dictionary. students[sid].preferences[int(rank)].add(projects[int(pid)]) Now this is very useful to me since I can find out all I want to about a student's preferred projects without having to run another check to pull up information about the project id. The form you see in the error has the object print information passed as: return "%s %s (Supervisor id: %s)" %(self.proj_id, self.proj_name, self.proj_sup) My questions are: I'm trying to store an object in a database field aren't I? Would the correct way then, be copying the project information (project id, name, etc) into its own table, referenced by the unique project id? That way I can just have the project id field for one of the student tables just be an integer id and when I need more information, just join the tables? So and so forth for other tables? If the above makes sense, then how does one maintain the relationship with a column of information in one table which is a key index on another table? Does this boil down into a database design problem? Are there any other elegant ways of accomplishing this? Apologies if this is a very long-winded question. It's rather crucial for me to solve this, so I've tried to explain as much as I can, whilst attempting to show that I'm trying (key word here sadly) to understand what could be going wrong.

  • Javascript phsyics in a 2d space

    - by eroo
    So, I am working on teaching myself Canvas (HTML5) and have most of a simple game engine coded up. It is a 2d representation of a space scene (planets, stars, celestial bodies, etc). My default "Sprite" class has a frame listener like such: "baseClass" contains a function that allows inheritance and applies "a" to "this.a". So, "var aTest = new Sprite({foo: 'bar'});" would make "aTest.foo = 'bar'". This is how I expose my objects to each other. { Sprite = baseClass.extend({ init: function(a){ baseClass.init(this, a); this.fields = new Array(); // list of fields of gravity one is in. Not sure if this is a good idea. this.addFL(function(tick){ // this will change to be independent of framerate soon. // and this is where I need help // gobjs is an array of all the Sprite objects in the "world". for(i = 0; i < gobjs.length; i++){ // Make sure its got setup correctly, make sure it -wants- gravity, and make sure it's not -this- sprite. if(typeof(gobjs[i].a) != undefined && !gobjs[i].a.ignoreGravity && gobjs[i].id != this.id){ // Check if it's within a certain range (obviously, gravity doesn't work this way... But I plan on having a large "space" area, // And I can't very well have all objects accounted for at all times, can I? if(this.distanceTo(gobjs[i]) < this.s.size*10 && gobjs[i].fields.indexOf(this.id) == -1){ gobjs[i].fields.push(this.id); } } } for(i = 0; i < this.fields.length; i++){ distance = this.distanceTo(gobjs[this.fields[i]]); angletosun = this.angleTo(gobjs[this.fields[i]])*(180/Math.PI); // .angleTo works very well, returning the angle in radians, which I convert to degrees here. // I have no idea what should happen here, although through trial and error (and attempting to read Maths papers on gravity (eeeeek!)), this sort of mimics gravity. // angle is its orientation, currently I assign a constant velocity to one of my objects, and leave the other static (it ignores gravity, but still emits it). this.a.angle = angletosun+(75+(distance*-1)/5); //todo: omg learn math if(this.distanceTo(gobjs[this.fields[i]]) > gobjs[this.fields[i]].a.size*10) this.fields.splice(i); // out of range, stop effecting. } }); } }); } Thanks in advance. The real trick is that one line: { this.a.angle = angletosun+(75+(distance*-1)/5); } This is more a physics question than Javascript, but I've searched and searched and read way to many wiki articles on orbital mathematics. It gets over my head very quickly. Edit: There is a weirdness with the SO formatting; forgives me, I is noobie.

  • Need help iteratating over an array, retrieve two possibilites, no repeats, for Poker AI

    - by elguapo-85
    Can't really think of a good way to word this question, nor a good title, and maybe the answer is so ridiculously simple that I am missing it. I am working on a poker AI, and I want to calculate the number of hands that exist which are better then mine, I understand how to that, but want I can't figure out is the best way to iterate over a group of cards. So I am at the flop, I know what my two cards are and there are 3 cards on the board. So there are 47 unknown cards and I want to iterate over all possible combination of those 47 cards assuming that two are passed out, so you can't have two cards of the same rank and suit, and you if you have previously calculated a set you don't want to do it over again, because I will being wasting time, and this will be called many times. If you don't understand want I am asking please tell me and I will clarify more. So I can set something up like this, if that element equals one, it means it is not in my hand and not on the board, 4 for each suit, and 13 for each rank. setOfCards[4][13] If I do a simple set of for loops like this: (pseudocode) //remove cards I know are in play from setOfCards by setting values to zero for(int i = 0; i < 4; i++) for(int j = 0; j < 13; j++) for(int k = 0; k < 4; k++) for(int l = 0; l < 4; l++) //skip if values equal zero card1 = setOfCards[i][j] card2 = setOfCards[k][l] //now compare card1, card2 and set of board cards So this is actually going to repeat many values, for example: card1 = AceOfHearts, card2 = KingOfHearts is the same as card1 = KingOfHearts, card2 = AceOfHearts. It will also alter my calculations. How should I go about avoiding this? Also is there a name for this technique? Thank you.

  • Help me understand this "Programming pearls" bitsort program

    - by ardsrk
    Jon Bentley in Column 1 of his book programming pearls introduces a technique for sorting a sequence of non-zero positive integers using bit vectors. I have taken the program bitsort.c from here and pasted it below: /* Copyright (C) 1999 Lucent Technologies */ /* From 'Programming Pearls' by Jon Bentley */ /* bitsort.c -- bitmap sort from Column 1 * Sort distinct integers in the range [0..N-1] */ #include <stdio.h> #define BITSPERWORD 32 #define SHIFT 5 #define MASK 0x1F #define N 10000000 int a[1 + N/BITSPERWORD]; void set(int i) { int sh = i>>SHIFT; a[i>>SHIFT] |= (1<<(i & MASK)); } void clr(int i) { a[i>>SHIFT] &= ~(1<<(i & MASK)); } int test(int i){ return a[i>>SHIFT] & (1<<(i & MASK)); } int main() { int i; for (i = 0; i < N; i++) clr(i); /*Replace above 2 lines with below 3 for word-parallel init int top = 1 + N/BITSPERWORD; for (i = 0; i < top; i++) a[i] = 0; */ while (scanf("%d", &i) != EOF) set(i); for (i = 0; i < N; i++) if (test(i)) printf("%d\n", i); return 0; } I understand what the functions clr, set and test are doing and explain them below: ( please correct me if I am wrong here ). clr clears the ith bit set sets the ith bit test returns the value at the ith bit Now, I don't understand how the functions do what they do. I am unable to figure out all the bit manipulation happening in those three functions. Please help.

  • Strange problems with PHP SOAP (private variable not persist + variables passed from client not work

    - by Tamas Gal
    I have a very strange problems in a PHP Soap implementation. I have a private variable in the Server class which contains the DB name for further reference. The private variable name is "fromdb". I have a public function on the soap server where I can set this variable. $client-setFromdb. When I call it form my client works perfectly and the fromdb private variable can be set. But a second soap client call this private variable loses its value... Here is my soap server setup: ini_set('soap.wsdl_cache_enabled', 0); ini_set('session.auto_start', 0); ini_set('always_populate_raw_post_data', 1); global $config_dir; session_start(); /*if(!$HTTP_RAW_POST_DATA){ $HTTP_RAW_POST_DATA = file_get_contents('php://input'); }*/ $server = new SoapServer("{$config_dir['template']}import.wsdl"); $server-setClass('import'); $server-setPersistence(SOAP_PERSISTENCE_SESSION); $server-handle(); Problem is that I passed this to the server: $client = new SoapClient('http://import.ingatlan.net/wsdl', array('trace' = 1)); $xml=''; $xml.=''; $xml.=''; $xml.=''; $xml.='Valaki'; $xml.=''; $xml.=''; $xml.=''; $xml.=''; $tarray = array("type" = 1, "xml" = $xml); try{ $s = $client-sendXml( $tarray ); print "$s"; } catch( SOAPFault $exception){ print "--- SOAP exception :{$exception}---"; print "LAST REQUEST :"; var_dump($client-_getLastRequest()); print "---"; print "LAST RESPONSE :".$client-_getLastResponse(); } So passed an Array of informations to the server. Then I got this exception: LAST REQUEST : <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Body><type>Array</type><xml/></SOAP-ENV:Body></SOAP-ENV:Envelope> Can you see the Array word between the type tag? Seems that the client only passed a reference or something like this. So I totaly missed :(

  • Can this be imporved? Scrubing of dangerous html tags.

    - by chobo2
    Hi I been finding that for something that I consider pretty import there is very little information or libraries on how to deal with this problem. I found this while searching. I really don't know all the million ways that a hacker could try to insert the dangerous tags. I have a rich html editor so I need to keep non dangerous tags but strip out bad ones. So is this script missing anything? It uses html agility pack. public string ScrubHTML(string html) { HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(html); //Remove potentially harmful elements HtmlNodeCollection nc = doc.DocumentNode.SelectNodes("//script|//link|//iframe|//frameset|//frame|//applet|//object|//embed"); if (nc != null) { foreach (HtmlNode node in nc) { node.ParentNode.RemoveChild(node, false); } } //remove hrefs to java/j/vbscript URLs nc = doc.DocumentNode.SelectNodes("//a[starts-with(translate(@href, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'javascript')]|//a[starts-with(translate(@href, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'jscript')]|//a[starts-with(translate(@href, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'vbscript')]"); if (nc != null) { foreach (HtmlNode node in nc) { node.SetAttributeValue("href", "#"); } } //remove img with refs to java/j/vbscript URLs nc = doc.DocumentNode.SelectNodes("//img[starts-with(translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'javascript')]|//img[starts-with(translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'jscript')]|//img[starts-with(translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'vbscript')]"); if (nc != null) { foreach (HtmlNode node in nc) { node.SetAttributeValue("src", "#"); } } //remove on<Event> handlers from all tags nc = doc.DocumentNode.SelectNodes("//*[@onclick or @onmouseover or @onfocus or @onblur or @onmouseout or @ondoubleclick or @onload or @onunload]"); if (nc != null) { foreach (HtmlNode node in nc) { node.Attributes.Remove("onFocus"); node.Attributes.Remove("onBlur"); node.Attributes.Remove("onClick"); node.Attributes.Remove("onMouseOver"); node.Attributes.Remove("onMouseOut"); node.Attributes.Remove("onDoubleClick"); node.Attributes.Remove("onLoad"); node.Attributes.Remove("onUnload"); } } // remove any style attributes that contain the word expression (IE evaluates this as script) nc = doc.DocumentNode.SelectNodes("//*[contains(translate(@style, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'expression')]"); if (nc != null) { foreach (HtmlNode node in nc) { node.Attributes.Remove("stYle"); } } return doc.DocumentNode.WriteTo(); }

  • Generating cache file for Twitter rss feed

    - by Kerri
    I'm working on a site with a simple php-generated twitter box with user timeline tweets pulled from the user_timeline rss feed, and cached to a local file to cut down on loads, and as backup for when twitter goes down. I based the caching on this: http://snipplr.com/view/8156/twitter-cache/. It all seemed to be working well yesterday, but today I discovered the cache file was blank. Deleting it then loading again generated a fresh file. The code I'm using is below. I've edited it to try to get it to work with what I was already using to display the feed and probably messed something crucial up. The changes I made are the following (and I strongly believe that any of these could be the cause): - Revised the time difference code (the linked example seemed to use a custom function that wasn't included in the code) Removed the "serialize" function from the "fwrites". This is purely because I couldn't figure out how to unserialize once I loaded it in the display code. I truthfully don't understand the role that serialize plays or how it works, so I'm sure I should have kept it in. If that's the case I just need to understand where/how to deserialize in the second part of the code so that it can be parsed. Removed the $rss variable in favor of just loading up the cache file in my original tweet display code. So, here are the relevant parts of the code I used: <?php $feedURL = "http://twitter.com/statuses/user_timeline/#######.rss"; // START CACHING $cache_file = dirname(__FILE__).'/cache/twitter_cache.rss'; // Start with the cache if(file_exists($cache_file)){ $mtime = (strtotime("now") - filemtime($cache_file)); if($mtime > 600) { $cache_rss = file_get_contents('http://twitter.com/statuses/user_timeline/75168146.rss'); $cache_static = fopen($cache_file, 'wb'); fwrite($cache_static, $cache_rss); fclose($cache_static); } echo "<!-- twitter cache generated ".date('Y-m-d h:i:s', filemtime($cache_file))." -->"; } else { $cache_rss = file_get_contents('http://twitter.com/statuses/user_timeline/#######.rss'); $cache_static = fopen($cache_file, 'wb'); fwrite($cache_static, $cache_rss); fclose($cache_static); } //END CACHING //START DISPLAY $doc = new DOMDocument(); $doc->load($cache_file); $arrFeeds = array(); foreach ($doc->getElementsByTagName('item') as $node) { $itemRSS = array ( 'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue ); array_push($arrFeeds, $itemRSS); } // the rest of the formatting and display code.... } ?> ETA 6/17 Nobody can help…? I'm thinking it has something to do with writing a blank cache file over a good one when twitter is down, because otherwise I imagine that this should be happening every ten minutes when the cache file is overwritten again, but it doesn't happen that frequently. I made the following change to the part where it checks how old the file is to overwrite it: $cache_rss = file_get_contents('http://twitter.com/statuses/user_timeline/75168146.rss'); if($mtime > 600 && $cache_rss != ''){ $cache_static = fopen($cache_file, 'wb'); fwrite($cache_static, $cache_rss); fclose($cache_static); } …so now, it will only write the file if it's over ten minutes old and there's actual content retrieved from the rss page. Do you think this will work?

  • Stored procedure to remove FK of a given table

    - by Nicole
    I need to create a stored procedure that: Accepts a table name as a parameter Find its dependencies (FKs) Removes them Truncate the table I created the following so far based on http://www.mssqltips.com/sqlservertip/1376/disable-enable-drop-and-recreate-sql-server-foreign-keys/ .

It uses html agility pack. public string ScrubHTML(string html) { HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(html); //Remove potentially harmful elements HtmlNodeCollection nc = doc.DocumentNode.SelectNodes("//script|//link|//iframe|//frameset|//frame|//applet|//object|//embed"); if (nc != null) { foreach (HtmlNode node in nc) { node.ParentNode.RemoveChild(node, false); } } //remove hrefs to java/j/vbscript URLs nc = doc.DocumentNode.SelectNodes("//a[starts-with(translate(@href, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'javascript')]|//a[starts-with(translate(@href, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'jscript')]|//a[starts-with(translate(@href, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'vbscript')]"); if (nc != null) { foreach (HtmlNode node in nc) { node.SetAttributeValue("href", "#"); } } //remove img with refs to java/j/vbscript URLs nc = doc.DocumentNode.SelectNodes("//img[starts-with(translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'javascript')]|//img[starts-with(translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'jscript')]|//img[starts-with(translate(@src, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'vbscript')]"); if (nc != null) { foreach (HtmlNode node in nc) { node.SetAttributeValue("src", "#"); } } //remove on<Event> handlers from all tags nc = doc.DocumentNode.SelectNodes("//*[@onclick or @onmouseover or @onfocus or @onblur or @onmouseout or @ondoubleclick or @onload or @onunload]"); if (nc != null) { foreach (HtmlNode node in nc) { node.Attributes.Remove("onFocus"); node.Attributes.Remove("onBlur"); node.Attributes.Remove("onClick"); node.Attributes.Remove("onMouseOver"); node.Attributes.Remove("onMouseOut"); node.Attributes.Remove("onDoubleClick"); node.Attributes.Remove("onLoad"); node.Attributes.Remove("onUnload"); } } // remove any style attributes that contain the word expression (IE evaluates this as script) nc = doc.DocumentNode.SelectNodes("//*[contains(translate(@style, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), 'expression')]"); if (nc != null) { foreach (HtmlNode node in nc) { node.Attributes.Remove("stYle"); } } return doc.DocumentNode.WriteTo(); }

  • can't the asp file system object access shared server paths?

    - by sushant
    i am using this code to access files and folders. <%@ Language=VBScript %><% option explicit dim sRoot, sDir, sParent, objFSO, objFolder, objFile, objSubFolder, sSize %> <META content="Microsoft Visual Studio 6.0" name=GENERATOR><!-- Author: Adrian Forbes --> <% sRoot = "D:Raghu" sDir = Request("Dir") sDir = sDir & "\" Response.Write "<h1>" & sDir & "</h1>" & vbCRLF Set objFSO = CreateObject("Scripting.FileSystemObject") on error resume next Set objFolder = objFSO.GetFolder(sRoot & sDir) if err.number <> 0 then Response.Write "Could not open folder" Response.End end if on error goto 0 sParent = objFSO.GetParentFolderName(objFolder.Path) ' Remove the contents of sRoot from the front. This gives us the parent ' path relative to the root folder ' eg. if parent folder is "c:webfilessubfolder1subfolder2" then we just want "subfolder1subfolder2" sParent = mid(sParent, len(sRoot) + 1) Response.Write "<table border=""1"">" ' Give a link to the parent folder. This is just a link to this page only pssing in ' the new folder as a parameter Response.Write "<tr><td colspan=3><a href=""browse.asp?dir=" & Server.URLEncode(sParent) & """>Parent folder</a></td></tr>" & vbCRLF ' Now we want to loop through the subfolders in this folder For Each objSubFolder In objFolder.SubFolders ' And provide a link to them Response.Write "<tr><td colspan=3><a href=""browse.asp?dir=" & Server.URLEncode(sDir & objSubFolder.Name) & """>" & objSubFolder.Name & "</a></td></tr>" & vbCRLF Next ' Now we want to loop through the files in this folder For Each objFile In objFolder.Files if Clng(objFile.Size) < 1024 then sSize = objFile.Size & " bytes" else sSize = Clng(objFile.Size / 1024) & " KB" end if ' And provide a link to view them. This is a link to show.asp passing in the directory and the file ' as parameters Response.Write "<tr><td><a href=""show.asp?file=" & server.URLEncode(objFile.Name) & "&dir=" & server.URLEncode (sDir) & """>" & objFile.Name & "</a></td><td>" & sSize & "</td><td>" & objFile.Type & "</td></tr>" & vbCRLF Next Response.Write "</table>" %> it works fine. but when i try to access something on shared path like: "\\cvrdd0110:share" it gives error. how to access these files? and sorry for formatting issues.
