  • .htaccess rewrite subdomains

    - by Cyclone
    Here is my current code: RewriteCond %{HTTP_HOST} !^example\.com [NC] #RewriteCond %{REQUEST_URI}!^something RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com RewriteRule (.*) something/%1/$1 [QSA,L] My goal is to rewrite http://*.example.com/whatever to http://example.com/something/*/whatever, assuming * is the same for both and whatever is the same for both. However, I believe this is causing an infinite loop somehow, so I added that commented out line (RewriteBase is / btw), but if I uncomment then the entire site is a 500 response code. Without that line, only the subdomains error. What am I doing wrong, and how can I fix this? I have already configured the server so anything gets redirected to my public_html folder. EDIT: For clarification, I am trying to do an internal redirect, not external. EDIT: There is not a flag for internal redirect it seems. Is there any place I can see the actual error message for the broken rewriterule? If I knew what was wrong I would be able to stand a better chance of fixing it.

  • Flash upload problems (FileReferenceList, timeouts, #2038 )

    - by binaryLV
    Hello! I'm having problems with timeouts while trying to upload multiple files by using FileReferenceList. upload() is being called in a loop for all selected files on Event.SELECT event of FileReferenceList, but only 2 files are being uploaded simultaneously (I also see 2 opened sockets that are used for uploading by running netstat -aon | find "127.0.0.1:80"). If uploading of any file is not started in 60 seconds, I get a #2038 error. E.g., if I try to upload three large files (like 500MB each), first two uploads are started immediately, third one is not started (because limit is 2 simultaneous uploads) and it fails after 60 seconds with #2038 error (I'm fairly sure that this is because of timeout - tested it). This could be solved by calling upload() only when uploading previous file is completed, but I don't want to "hard-code" the number of possible simultaneous uploads (2 on my PC). Is there any way to get/set this number at runtime?

  • Creating matrix of maximum values indices in MATLAB

    - by Gacek
    Using MATLAB, I have an array of values of size 8 rows x N columns. I need to create a matrix of the same size, that counts maximum values in each column and puts 1 in the cell that contains maximum value, and 0 elsewhere. A little example. Lets assume we have an array of values D: D = 0.0088358 0.0040346 0.40276 0.0053221 0.017503 0.011966 0.015095 0.017383 0.14337 0.38608 0.16509 0.15763 0.27546 0.25433 0.2764 0.28442 0.01629 0.0060465 0.0082339 0.0099775 0.034521 0.01196 0.016289 0.021012 0.12632 0.13339 0.11113 0.10288 0.3777 0.19219 0.005005 0.40137 Then, the output matrix for such matrix D would be: 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 Is there a way to do it without catching vector of indices from max function and then putting ones in the right place using for loop?

  • Get positions for NAs only in the "middle" of a matrix column

    - by Abiel
    I want to obtain an index that refers to the positions of NA values in a matrix where the index is true if a given cell is NA and there is at least one non-NA value before and after it in the column. For example, given the following matrix [,1] [,2] [,3] [,4] [1,] NA 1 NA 1 [2,] 1 NA NA 2 [3,] NA 2 NA 3 the only value of the index that comes back TRUE should be [2,2]. Is there a compact expression for what I want to do? If I had to I could loop through columns and use something like min(which(!is.na(x[,i]))) to find the first non-NA value in each column, and then set all values before that to FALSE (and the same for all values after the max). This way I would not select leading and trailing NA values. But this seems a bit messy, so I'm wondering if there is a cleaner expression that does this without loops.

  • Efficiently compute the row sums of a 3d array in R

    - by Gavin Simpson
    Consider the array a: > a <- array(c(1:9, 1:9), c(3,3,2)) > a , , 1 [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 , , 2 [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 How do we efficiently compute the row sums of the matrices indexed by the third dimension, such that the result is: [,1] [,2] [1,] 12 12 [2,] 15 15 [3,] 18 18 ?? The column sums are easy via the 'dims' argument of colSums(): > colSums(a, dims = 1) but I cannot find a way to use rowSums() on the array to achieve the desired result, as it has a different interpretation of 'dims' to that of colSums(). It is simple to compute the desired row sums using: > apply(a, 3, rowSums) [,1] [,2] [1,] 12 12 [2,] 15 15 [3,] 18 18 but that is just hiding the loop. Are there other efficient, truly vectorised, ways of computing the required row sums?

  • Distance between numpy arrays, columnwise

    - by Jaapsneep
    I have 2 arrays in 2D, where the column vectors are feature vectors. One array is of size F x A, the other of F x B, where A << B. As an example, for A = 2 and F = 3 (B can be anything): arr1 = np.array( [[1, 4], [2, 5], [3, 6]] ) arr2 = np.array( [[1, 4, 7, 10, ..], [2, 5, 8, 11, ..], [3, 6, 9, 12, ..]] ) I want to calculate the distance between arr1 and a fragment of arr2 that is of equal size (in this case, 3x2), for each possible fragment of arr2. The column vectors are independent of each other, so I believe I should calculate the distance between each column vector in arr1 and a collection of column vectors ranging from i to i + A from arr2 and take the sum of these distances (not sure though). Does numpy offer an efficient way of doing this, or will I have to take slices from the second array and, using another loop, calculate the distance between each column vector in arr1 and the corresponding column vector in the slice?

  • Content Being Echoed Below Footer in Category Post Template

    - by poindexter
    I have created a category template in Wordpress for all posts that are in the 'blog' category. The file name is single-blog.php. There is some conditional code in single.php that checks whether the post is in the 'blog' category and if it is it redirects it to single-blog.php. That seems to be working fine. The problem is that on all the individual 'blog' categorized posts the post title and content are echoed below the footer of the page. I do not know why they are showing up and I haven't been able to stop it or hide it. The Loop is getting closed on the template page, but I'm wondering if the Loop from single.php is somehow also being sent over. You can view an example of the problem here: http://69.20.59.228/2010/03/test-blog-post/ Please let me know if you have any suggestions. I am posting two sections of code below. The first is the conditional call in single.php.

  • PHP: passing GET between multiple pages

    - by aterimperator
    I'm building a set of pages where I have a number of GET variables and it is often valuable to keep passing it along to the next page. This leads to ugly code where I have to have "if this $_GET variable is set, dynamically add it to this hyperlink". This is, in many senses, not a problem; but I had the thought "there must be a better way to do this", I mean after all basically all I want is to take the '?' and everything after it and append it to the links on that page, it would seem this should be rather simple (or at least possible to do in a for loop). I tried google searching but couldn't find anything, so I figured I'd see if any of you happen to know. Why not use SESSION? Because these pages need to be capable of being bookmarked. Thank you.

  • Wireshark Plugin: Dissecting Payloads With Multiple Packets Per UDP Frame

    - by John Dibling
    I am writing a Wireshark plugin to dissect a protocol that places multiple application-level packets in a single UDP frame. There is no enclosing protocol that indicates how many packets there are in the frame. So essentially, the payload coming down the wire will look like this: uint64 sequence1 uint64 data1 uint8 flags1 uint64 sequence2 uint64 data2 uint8 flags2 : : : uint64 sequence_n uint64 data_n uint8 flags_n In my server code that actually processes this information, I simply loop through the frame until I reach the end. In looking through the plugins included with the wireshark source code, I didn't see any protocols that did any looping like this. I know other protocols pack multiple payloads per frame. What is the cannonical or standard way to handle protocols like this in a Wireshark dissector?

  • .NET | Persist multiple objects in minimum number of queries

    - by VarunGupta
    I have a list of objects which needs to be persisted in a SQL Server database table, where each object gets persisted as single record. i.e. List of objects result in insertion of multiple records. Trivial way of saving the objects is to loop over the list and fire a query/stored procedure/etc. for saving that record. But this results in multiple database interactions. Is there a way to persist the list of objects in lesser number of database interactions?

  • how to cout a vector of structs (that's a class member, using extraction operator)

    - by Julz
    hi, i'm trying to simply cout the elements of a vector using an overloaded extraction operator. the vector contians Point, which is just a struct containing two doubles. the vector is a private member of a class called Polygon, so heres my Point.h #ifndef POINT_H #define POINT_H #include <iostream> #include <string> #include <sstream> struct Point { double x; double y; //constructor Point() { x = 0.0; y = 0.0; } friend std::istream& operator >>(std::istream& stream, Point &p) { stream >> std::ws; stream >> p.x; stream >> p.y; return stream; } friend std::ostream& operator << (std::ostream& stream, Point &p) { stream << p.x << p.y; return stream; } }; #endif my Polygon.h #ifndef POLYGON_H #define POLYGON_H #include "Segment.h" #include <vector> class Polygon { //insertion operator needs work friend std::istream & operator >> (std::istream &inStream, Polygon &vertStr); // extraction operator friend std::ostream & operator << (std::ostream &outStream, const Polygon &vertStr); public: //Constructor Polygon(const std::vector<Point> &theVerts); //Default Constructor Polygon(); //Copy Constructor Polygon(const Polygon &polyCopy); //Accessor/Modifier methods inline std::vector<Point> getVector() const {return vertices;} //Return number of Vector elements inline int sizeOfVect() const {return vertices.size();} //add Point elements to vector inline void setVertices(const Point &theVerts){vertices.push_back (theVerts);} private: std::vector<Point> vertices; }; and Polygon.cc using namespace std; #include "Polygon.h" // Constructor Polygon::Polygon(const vector<Point> &theVerts) { vertices = theVerts; } //Default Constructor Polygon::Polygon(){} istream & operator >> (istream &inStream, Polygon::Polygon &vertStr) { inStream >> ws; inStream >> vertStr; return inStream; } // extraction operator ostream & operator << (ostream &outStream, const Polygon::Polygon &vertStr) { outStream << vertStr.vertices << endl; return outStream; } i figure my Point insertion/extraction is right, i can insert and cout using it and i figure i should be able to just...... cout << myPoly[i] << endl; in my driver? (in a loop) or even... cout << myPoly[0] << endl; without a loop? i've tried all sorts of myPoly.at[i]; myPoly.vertices[i]; etc etc also tried all veriations in my extraction function outStream << vertStr.vertices[i] << endl; within loops, etc etc. when i just create a... vector<Point> myVect; in my driver i can just... cout << myVect.at(i) << endl; no problems. tried to find an answer for days, really lost and not through lack of trying!!! thanks in advance for any help. please excuse my lack of comments and formatting also there's bits and pieces missing but i really just need an answer to this problem thanks again

  • n-grams from text in PostgreSQL

    - by harshsinghal
    I am looking to create n-grams from text column in PostgreSQL. I currently split(on white-space) data(sentences) in a text column to an array. select regexp_split_to_array(sentenceData,E'\s+') from tableName Once I have this array, how do I go about: Creating a loop to find n-grams, and write each to a row in another table Using unnest I can obtain all the elements of all the arrays on separate rows, and maybe I can then think of a way to get n-grams from a single column, but I'd loose the sentence boundaries which I wise to preserve. Sample SQL code for PostgreSQL to emulate the above scenario create table tableName(sentenceData text); INSERT INTO tableName(sentenceData) VALUES('This is a long sentence'); INSERT INTO tableName(sentenceData) VALUES('I am currently doing grammar, hitting this monster book btw!'); INSERT INTO tableName(sentenceData) VALUES('Just tonnes of grammar, problem is I bought it in TAIWAN, and so there aint any englihs, just chinese and japanese'); select regexp_split_to_array(sentenceData,E'\s+') from tableName; select unnest(regexp_split_to_array(sentenceData,E'\s+')) from tableName;

  • cannot read but can write on serial port through Android Emulator

    - by Aad
    I am working on a program that is communicating with serial port over USB through Android emulator. emulator -qemu -serial /dev/ttyUSB0 The emulator is able to open the port and write into it. However, read is not happening. The program has a timeout for read maintained by a timer. The read happens in a separate 'read' thread. The main thread has a socketpair fd pair to signal the read-thread that the serial port is closed post timeout. In the read-thread, polling happens(poll() function call) over the 2 file-descriptors: one is serial port fd, the other is one of the socketpair. The board that I have connected to works fine with sending commands over 'cutecom' The poll never succeeds for serial port. However, poll succeeds for 'socketpair'ed fd and the thread ends on a close-signal sent from main-thread post timeout. Ouestions: Are there any special settings for read as even loop-back fails Are there differences between settings for read and write on a serial port?

  • zend_acl: Adding extra resources dynamically and getting a param predispatch

    - by Timmeh
    First sorry about the woffle as I'm not sure how best to describe this. Basically I am not sure how I can get param in the bootstrap before the controller is loaded, but here is the long winded version... I have got an acl class storing all my default resources in. All my page/post content is a database and I want the admin the ability to choose who which role the page would become available. I know it is possible just to loop through the database table and add them all in at once, but I am concerned that this is a drain on resources. I have it working whereby my access check plugin can call a dynamic permission function, but I need to get the parameter of the current page ID and it's permission to set it before the controller is loaded. Does that make sense or am I worry over nothing and I should just get the resources of all the pages at once? thanks in advance for reading my garble!!

  • Using Linq to select a range of members in a list

    - by clintp
    Given a list of elements like so: int[] ia = new int[] { -4, 10, 11, 12, 13, -1, 9, 8, 7, 6, 5, 4, -2, 6, 15, 32, -5, 6, 19, 22 }; Is there an easy way in Linq to do something along the lines of "Select the elements from the -1 up to the next negative number (or the list exhausts)"? A successful result for -1 would be (-1, 9, 8, 7, 6, 5, 4). Using -2 would give the result (-2, 6, 15, 32). Not a homework problem. I'm just looking at an implementation using a bool, a for loop, and an if wondering if there's a cleaner way to do it.

  • Best Dijkstra papers to explain this quote?

    - by jemfinch
    I was enjoying "The Humble Programmer" earlier today and ran across this choice quote: Therefore, for the time being and perhaps forever, the rules of the second kind present themselves as elements of discipline required from the programmer. Some of the rules I have in mind are so clear that they can be taught and that there never needs to be an argument as to whether a given program violates them or not. Examples are the requirements that no loop should be written down without providing a proof for termination nor without stating the relation whose invariance will not be destroyed by the execution of the repeatable statement. I'm looking for which of Dijkstra's 1300+ writings best describe in further detail rules such as he was describing above.

  • How do you move the pointer up or down multiple lines with Emacs?

    - by Peter
    I can move my pointer up and down one line with my arrow key just fine in Emacs, so I'd like to redefine C-n and C-p to move up and down 5 lines at a time. I'm just beginning to learn how to use Emacs, and elisp is very alien to me. I tried using the GNU Emacs lisp reference, but I couldn't find how to bind a keystroke to multiple commands. Here's what I have so far (concentrating on the moving up definition): (global-set-key "\C-p" '(loop for i in '(1 2 3 4 5) do ('previous-line))) But, this brings up an error message when I hit C-p, "Wrong type argument." Any suggestions? Thanks!

  • Determining Excel spreadsheet format before Data Flow Task

    - by Josh Larsen
    I'm working on an SSIS package which uses a for each loop to iterate through excel files in a directory and a data flow task to import them. The issue I'm having is that the project manager I'm working with doesn't think the users will always follow the structure. So if a file is in the folder and the package tries to import it but the spreadsheet is missing columns or has extra columns it generates and error of course. Even though I have the task set to not fail the package; the package does indeed fail and then the other files aren't imported. So, I'm wondering what is the easiest way to either determine the spreadsheet is incorrectly formatted, or stop the error from failing the package execution? After taking said step I would just use a file copy task to move the file to a "Failure" folder. Then continue on processing the spreadsheets.

  • Why are nanosleep() and usleep() too slow?

    - by user351990
    I have a program that generates packets to send to a receiver. I need an efficient method of introducing a small delay between the sending of each packet so as not to overrun the receiver. I've tried usleep() and nanosleep() but they seem to be too slow. I've implemented a busy wait loop and had more success, but it's not the most efficient method, I know. I'm interested in anyone's experiences in trying to do what I'm doing. Do others find usleep() and nanosleep() to function well for this type of application? Thanks, Danny Llewallyn

  • Sharing [config] data across modules,functions

    - by williamstw
    I have some configuration data in a config file that I read off disk when the app starts. I need to make that configuration data available to other functions/modules in the application. I started down the path of looking into ets/mnesia to store the data on startup to make it shared among all processes, but then my inner voice cautioned me that there must be a more functional, erlang-y way to do this. The only alternate approach I've come up with so far is setting up a module that has an actor loop that reads the data on startup and responds to messages like {Key, From} and responds by From ! {ok,Value}. Then, I gave up and decided to ask... Thanks, --tim

    Hello.. Firstly let me explain the code below is just a tiny snippet of the code I'm using on the working site. Basically I'm hoping someone can help me rewrite just the function below to enable parallel CURL calls... that way it will fit nicely into the existing code without me having to rewrite the whole from the ground up like some of the samples I've been finding today any ideas? function get_data($url) { $ch = curl_init(); $timeout = 5; curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5); $data = curl_exec($ch); curl_close($ch); return $data; } p.s. $url goes through a huge bunch of urls in a loop already so I'd hole to keep that intact..

  • Avoid IF statement after condition has been met

    - by greye
    I have a division operation inside a cycle that repeats many times. It so happens that in the first few passes through the loop (more or less first 10 loops) the divisor is zero. Once it gains value, a div by zero error is not longer possible. I have an if condition to test the divisor value in order to avoid the div by zero, but I am wondering that there is a performance impact that evaluating this if will have for each run in subsequent loops, especially since I know it's of no use anymore. How should this be coded? in Python?
