  • Converting human readable date into integer values

    - by kahrn
    Hello all, I am looking to do something really simple. Merely convert a string, such as 'december' into something I can use with MySQL (such as '12'). At the moment I use a dict, month_map = { 'december': '12', 'november': '11', 'october': '10', 'september': '09', 'august': '08', 'july': '07', 'june': '06', 'may': '05', 'april': '04', 'march': '03', 'february': '02', 'january': '01' } and then month_map.get('december'). Does any function already exist within the standard python modules that can achieve this? Apologies if this has already been asked.. the questions I have found using search seem a little different.

  • Query to update rowNum

    - by BrokeMyLegBiking
    Can anyone help me write this query more efficiently? I have a table that captures TCP traffic, and I'd like to update a column called RowNumForFlow which is simly the sequential number of the IP packet in that flow. The code below works fine, but it is slow. declare @FlowID int declare @LastRowNumInFlow int declare @counter1 int set @counter1 = 0 while (@counter1 < 1) BEGIN set @counter1 = @counter1 + 1 -- 1) select top 1 @FlowID = t.FlowID from Traffic t where t.RowNumInFlow is null if (@FlowID is null) break -- 2) set @LastRowNumInFlow = null select top 1 @LastRowNumInFlow = RowNumInFlow from Traffic where FlowID=@FlowID and RowNumInFlow is not null order by ID desc if @LastRowNumInFlow is null set @LastRowNumInFlow = 1 else set @LastRowNumInFlow = @LastRowNumInFlow + 1 update Traffic set RowNumInFlow = @LastRowNumInFlow where ID = (select top 1 ID from Traffic where flowid = @FlowID and RowNumInFlow is null) END Example table values after query has run: ID FlowID RowNumInFlow 448923 44 1 448924 44 2 448988 44 3 448989 44 4 448990 44 5 448991 44 6 448992 44 7 448993 44 8 448995 44 9 448996 44 10 449065 44 11 449063 45 1 449170 45 2 449171 45 3 449172 45 4 449187 45 5

  • Intercepting POST in WebView using NDK

    - by ravi
    I am trying to intercept http POST method in WebView android, but not able to find any suitable method for the same. In API 11 there is a method shouldInterceptRequest, but it gives only webviewq and url as parameters so cater only GET request, it doesnot provide POST body data and request type indicator. My question : Is there any way to override this method in android NDK ? or if i can pass a flag which identify request and also i can provide POST data. Also if you have any other solution, tell me.

  • Use concat and maintain length of variable

    - by user1682055
    I'm trying to use concat on some variables. These variables have been declared as chars: declare v_order_date char(10); declare v_quantity char(11); declare v_plant char(100); I have a cursor where I am setting these as some outputs. To call the results, I am setting v_msg as set v_msg := concat( v_msg, '\n', v_order_date, v_quantity, v_plant); However, the result I am getting when I select v_msg is: 2012-01-222501008 Creeping Buttercup but I want to maintain the length of the declared variables in my select that looks like this 2012-01-22 250 1008 Creeping Buttercup Are there any suggestions? Thank you.

  • What's the best way to build software to not require the newest glibc?

    - by ZorbaTHut
    I'm attempting to build a binary package that can be run on multiple Linux distributions. It's currently built on Ubuntu 10.04, but it fails on Ubuntu 8.04 with the following error: ./test: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ./test) ./test: /usr/lib/libstdc.so.6: version `GLIBC_2.11' not found (required by ./test) What's the preferred way to solve this problem? Is there a way to install an old glibc on a new box and build against it, or do I have to build on an old distribution? And if I build against an old glibc, will it work on a new glibc? Or, alternatively, are there just some handy compiler flags or packages I could install to solve the problem?

  • why my array is losing it's contents when I refresh the page?

    - by Fernando SBS
    I have created an: var checkboxFarm = new Array(); then I want to record a checkbox status in that array, as there are 11 checkboxes. Button.addEventListener("click", function() { rp_farmAtivada(index); }, false); when clicked change the variable in the array: function rp_farmAtivada(index) { checkboxFarm[index] = !checkboxFarm[index]; }; but every time I refresh the page it loses all the checkboxes status and I'm aware that all that array gets the "undefined" value. the checkboxFarm array is defined in the beginning of the script, so it should have a global scope. Am I missing something?

  • How can I find all the supported weights of a Font in Java?

    - by William
    How can I find all the available font weights for a given font in Java? The TextAttribute for font weight lists 11 different weight constants, way more than just Font.PLAIN and Font.BOLD. I'd like to know which ones actually exist for a given font family, so I can make sure I'm only using weights for which a font face exists. The getAttributes() and getAvailableAttributes() methods in Font will only show me whether or not the Font supports the FONT_WEIGHT attribute, not which weight values it supports. If I just pass in a particular value to see what I get back, I don't have any guarantee that I'll get what I asked for. The TextAttribute class says "The values for WEIGHT, WIDTH, and POSTURE are interpolated by the system, which can select the 'nearest available' font or use other techniques to approximate the user's request."

  • MySQL ODBC error "server has gone away"

    - by digitala
    Occasionally we're seeing an error from ASP pages: Microsoft OLE DB Provider for ODBC Drivers error '80004005' [MySQL][MyODBC 5.00.11][MySQL] 2006 MySQL server has gone away We're handling it the best way we can in ASP but it still crops up. I think it's more to do with the MySQL ODBC driver than the ASP code. We never see this with PHP code we also have running under the same IIS server, however PHP re-connects each time it is ran, whereas I believe the ODBC driver connects once and stays connected. I've checked the settings in the driver but there doesn't seem to be anything I can change to help mitigate the problem. Can anyone explain why this is happening and how to reduce the number of times it happens?

  • Count in base 2, 3, 4 etc in Java and output all permutations

    - by tree-hacker
    I want to write a function in Java that takes as input an integer and outputs every possible permutation of numbers up to that integer. For example: f(1) 0 f(2) should output: 00 01 10 11 f(3) should output: 000 001 002 010 011 012 020 021 022 100 .... 220 221 222 That is it should output all 27 permutations of the digits of the numbers 0, 1, 2. f(4) should output 0000 0001 0002 0003 0010 ... 3330 3331 3332 3333 f(4) should output 00000 00001 ... 44443 44444 I have been trying to solve this problem but cannot seem to work out how to do it and keep getting confused by how many loops I need. Does anyone know how to solve this problem? Thanks in advance.

  • Why does the right-shift operator produce a zero instead of a one?

    - by mrt181
    Hi, i am teaching myself java and i work through the exercises in Thinking in Java. On page 116, exercise 11, you should right-shift an integer through all its binary positions and display each position with Integer.toBinaryString. public static void main(String[] args) { int i = 8; System.out.println(Integer.toBinaryString(i)); int maxIterations = Integer.toBinaryString(i).length(); int j; for (j = 1; j < maxIterations; j++) { i >>= 1; System.out.println(Integer.toBinaryString(i)); } In the solution guide the output looks like this: 1000 1100 1110 1111 When i run this code i get this: 1000 100 10 1 What is going on here. Are the digits cut off? I am using jdk1.6.0_20 64bit. The book uses jdk1.5 32bit.

  • Image processing custom filter 7 by 7

    Lets say I have a 7 by 7 neighborhood around a pixel that looks like this 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 and I wanna filter the above by replacing the pixel p by the average of those pixels whose value lie in the range -10<=p_value <=10. I am new to image processing and I think in this case p_value is 25 and around 25 that are many pixel values in that range but don't exactly know to construct a convolution filter out of it.

  • Python: How to run unittest.main() for all source files in a subdirectory?

    - by Pete
    I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

  • C++ shared libraries

    - by saminny
    Hi, I am trying to get my head around the way shared libraries work in the c++ unix environment. I understand we only need header files and no shared libraries specification when compiling code. But if I want to create an executable or shared library from my compiled files, do I need to specify shared library dependencies (those are dynamic)? And do the paths of shared libraries need to match the path at runtime loading? I am using Linux 2.6.18-164.11.1.el5 #1 SMP x86_64 GNU/Linux I am having a problem where my code is not able to pick up a library at runtime. I have tried setting LD_LIBRARY_PATH and PATH. But at runtime when I run the executable, I get the following error: Error: librc.so: cannot open shared object file: No such file or directory Sam
