  • Interrupt an Http Request blocked in read() on Android

    - by twk
    Using the Apache Http stack on Android, I'm trying to force a thread out of a call to read. This is what the stack looks like: OSNetworkSystem.receiveStreamImpl(FileDescriptor, byte[], int, int, int) line: not available [native method] OSNetworkSystem.receiveStream(FileDescriptor, byte[], int, int, int) line: 478 PlainSocketImpl.read(byte[], int, int) line: 565 SocketInputStream.read(byte[], int, int) line: 87 SocketInputBuffer(AbstractSessionInputBuffer).fillBuffer() line: 103 SocketInputBuffer(AbstractSessionInputBuffer).read(byte[], int, int) line: 134 IdentityInputStream.read(byte[], int, int) line: 86 EofSensorInputStream.read(byte[], int, int) line: 159 Fetcher.readStream() line: 89 I've tried InputStream.close(), Thread.Interrupt(), and HttpUriRequest.abort(), without any success. Any ideas? I'm also open to some kind of non-blocking IO, but I don't see any way to do that with the HttpUriRequest object. Thanks!

  • Math: How to sum each row of a matrix

    - by macek
    I have a 1x8 matrix of students where each student is a 4x1 matrix of scores. Something like: SCORES S [62, 91, 74, 14] T [59, 7 , 59, 21] U [44, 9 , 69, 6 ] D [4 , 32, 28, 53] E [78, 99, 53, 83] N [48, 86, 89, 60] T [56, 71, 15, 80] S [47, 67, 79, 40] Main question: Using sigma notation, or some other mathematical function, how can I get a 1x8 matrix where each student's scores are summed? # expected result TOTAL OF SCORES S [241] T [146] U [128] D [117] E [313] N [283] T [222] S [233] Sub question. To get the average, I will multiply the matrix by 1/4. Would there be a quicker way to get the final result? AVERAGE SCORE S [60.25] T [36.50] U [32.00] D [29.25] E [78.25] N [70.75] T [55.50] S [58.25] Note: I'm not looking for programming-related algorithms here. I want to know if it is possible to represent this with pure mathematical functions alone.

  • Add title to meta analysis forest plot

    - by Timothy Alston
    I am meta-analysing some studies and drawing a forest plot for my results. However I can`t seem to get the forest plot to display the title. An example of my code is: require(meta) parameter1<-metaprop(sm="PLOGIT", event=c(4,16,3,2,10,1,0,2), n=c(90,402,89,29,153,86,21,48), level = 0.95, studlab=c("study 1", "study 2", "study 3", "study 4", "study 5", "study 6", "study 7", "study 8"), title="meta analysis 1") forest(parameter1) When it produces the forest plot, the title "meta analysis 1" is missing. How can I add this in? Thanks in advance, Timothy

  • Executing shell commands from Java

    - by Lauren?iu Dascalu
    Hello, I'm trying to execute a shell command from a java application, on the GNU/Linux platform. The problem is that the script, that calls another java application, never ends, although it runs successfully from bash. I tried to debug it: (gdb) bt #0 0xb773d422 in __kernel_vsyscall () #1 0xb7709b5d in pthread_join (threadid=3063909232, thread_return=0xbf9cb678) at pthread_join.c:89 #2 0x0804dd78 in ContinueInNewThread () #3 0x080497f6 in main () I tried with: ProcessBuilder(); and Runtime.getRuntime().exec(cmd); Looks like it waits for something to finish. Any ideas? Thanks, Lauren?iu

  • Beginner having a problem with classes

    - by David
    I'm working through O'Reilly's "Learning Python" and having a problem with classes. I think I understand the concept, but in practice have stumbled upon this problem. Fron page 88-89: >>> class Worker: def __innit__(self, name, pay): self.name=name self.pay=pay def lastName(self): return self.name.split()[-1] def giveRaise(self, percent): self.pay*=(1.0+percent) Then the book says "Calling the class like a function generates instances of a new type ...etc" and gives this example. bob = Worker('Bob Smith', 50000) This gives me this error: TypeError: this constructor takes no arguments. And then I start muttering profanities. So what am I doing wrong here? Thanks for the help.

  • matlab noninteger step indexing

    - by rlbond
    So, I have a vector: k = 1:100; And I want to take 19 elements from it, which are roughly equally-spaced. So I write this: m = k(1:(99/18):end); This works great, except for a tiny problem: Warning: Integer operands are required for colon operator when used as index m = 1 7 12 18 23 29 34 40 45 51 56 62 67 73 78 84 89 95 100 Now, I understand why this comes up, but I'd like to get rid of that warning. Is there a "right" way to do this without a warning?

  • Utilising cssText to set styles with JavaScript

    - by Rajat
    I was going through Nicholas Zakas presentation on JavaScript here : http://www.slideshare.net/nzakas/writing-efficient-javascript (slide number: 89/139) He recommends using cssText property whenever you are setting a bunch of styles through JavaScript. The best solution is obviously adding those styles to a class and then using JS to add the classname to an element.However, in many situations, We resort to just setting the properties directly within JS when the number of properties are low. It seems from his presentation that using cssText property would be more efficient in such scenarios.I tried to look up more on the property but couldn't find much information. Has anyone used the 'cssText' property ? It would be great to have some more technical info on how the property helps.

  • Why doesn't negative values for the second index in a jagged array work in Python?

    - by univerio
    For example, if I have the following (data from Project Euler): s = [[75], [95, 64], [17, 47, 82], [18, 35, 87, 10], [20, 4, 82, 47, 65], [19, 1, 23, 75, 3, 34], [88, 2, 77, 73, 7, 63, 67], [99, 65, 4, 28, 6, 16, 70, 92], [41, 41, 26, 56, 83, 40, 80, 70, 33], [41, 48, 72, 33, 47, 32, 37, 16, 94, 29], [53, 71, 44, 65, 25, 43, 91, 52, 97, 51, 14], [70, 11, 33, 28, 77, 73, 17, 78, 39, 68, 17, 57], [91, 71, 52, 38, 17, 14, 91, 43, 58, 50, 27, 29, 48], [63, 66, 4, 68,89, 53, 67, 30, 73, 16, 69, 87, 40, 31], [4, 62, 98, 27, 23, 9, 70, 98, 73, 93, 38, 53, 60, 4, 23]] Why does s[1:][:-1] give me the same thing as s[1:] instead of (what I want) [s[i][:-1] for i in range(1,len(s))]. In other words, why does Python ignore my second index?

  • appending SVG string to dom

    - by Wieringen
    I'm trying to append a string of svg elements to the dom. This is my setup. var oFragment = ''; for (var i = 0; i < 10; i++) { oFragment += '<g><path id="note-1" d="M 6,3 84,6 c 0,0 -6,76 14,91 L 58,97 19,89 c 0,0 -24,-5 -13,-86 z" style="fill:#ffc835;" /></g> '; } Here is what i tried. It gives the following error: "parseXML is not defined" var oSVG = document.getElementById("svg-wall").getSVGDocument(); var oNotes = oSVG.getElementById('notes'); oNotes.appendChild(parseXML(oFragment, document)); So my question is what am i doing wrong and is this even the best way to append a svg string to the dom?

  • What's your favorite implementation of producing the fibonacci sequence?

    - by Terry Donaghe
    Best, most creative, most clever, fastest, smallest, written in weirdest language, etc etc. For those not familiar with this staple of programming exam question / interview question, check this out: Fibonacci Sequence at Wikipedia The question would be, write a simple program which will spit out the first n digits of the Fibonacci sequence. So, if n == 12, we produce: 0 1 1 2 3 5 8 13 21 34 55 89 144 Your implementation becomes more interesting when you set n to larger values. How long does it take your implementation to return a 25 digit sequence? How about 100?

  • Modulus PHP Problem

    - by Eli
    I have a problem, I am trying to calculate what the lowest prime is of a number but I do not understand the result that PHP is giving me. If I have this number $number = 600851475143; Then I modulus it: $primes = array( 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97); foreach($primes as $key=>$value) { if($number % $value == 0 ) {echo $value; break; } } Why is it that $value = 3? If $value = 3, that means that 600851475143 / 3 should be an integer, but its not. So I do not understand why that if() evaluates to true?

  • How to use PHP fgetcsv to create an array for each piece of data in csv file?

    - by Olivia
    I'm trying to import data from a csv file to some html code to use it in a graph I have already coded. I'm trying to use PHP and fgetcsv to create arrays for each separate piece of data to use PHP to put it into the html code. I know how to open the csv file and to print it using PHP, and how to print each separate row, but not each piece of data separated by a comma. Is there a way to do this? If this helps, this is the csv data I am trying to import. May 10,72,12,60 May 11,86,24,62 May 12,67,32,34 May 13,87,12,75 May 14,112,23,89 May 17,69,21,48 May 18,98,14,84 May 19,115,18,97 May 20,101,13,88 May 21,107,32,75 I hope that makes sense.

    I'm sure there is an easy way to do this, but I can't think of it right now. Is there an array function or something that lets me search through an array and find the item that has a certain property value? For example: $people = array( array( 'name' => 'Alice', 'age' => 25, ), array( 'name' => 'Waldo', 'age' => 89, ), array( 'name' => 'Bob', 'age' => 27, ), ); How can I find and get Waldo?

  • Any way to avoid a filesort when order by is different to where clause?

    - by Julian
    I have an incredibly simple query (table type InnoDb) and EXPLAIN says that MySQL must do an extra pass to find out how to retrieve the rows in sorted order. SELECT * FROM `comments` WHERE (commentable_id = 1976) ORDER BY created_at desc LIMIT 0, 5 exact explain output: table select_type type extra possible_keys key key length ref rows comments simple ref using where; using filesort common_lookups common_lookups 5 const 89 commentable_id is indexed. Comments has nothing trick in it, just a content field. The manual suggests that if the order by is different to the where, there is no way filesort can be avoided. http://dev.mysql.com/doc/refman/5.0/en/order-by-optimization.html I also tried order by id as well as it's equivalent but makes no difference, even if I add id as an index (which I understand is not required as id is indexed implicitly in MySQL). thanks in advance for any ideas!
