  • Help with Regex statement in Ruby

    - by user336777
    I have a string called 'raw'. I am trying to parse it in ruby in the following way: raw = "HbA1C ranging 8.0—10.0%" raw.scan /\d*.?\d+[ ](-+|\342\200\224)[ ]\d*.?\d+/ The output from the above is []. I think it should be: ["8.0—10.0"]. Does anyone have any insight into what is wrong with the above regex statement? Note: \342\200\224 is equal to '—'. The piece that is not working is: (-+|\342\200\224) I think it should be equivalent to saying, match on 1 or more '-' OR match on the string \342\200\224. Any help would be greatly appreciated it!

  • Divide numpy array

    - by BandGap
    Hi all I have some data represented in a 1300x1341 matrix. I would like to split this matrix in several pieces (e.g. 9) so that I can loop over and process them. The data needs to stay ordered in the sense that x[0,1] stays below (or above if you like) x[0,0] and besides x[1,1]. Just like if you had imaged the data, you could draw 2 vertical and 2 horizontal lines over the image to illustrate the 9 parts. If I use numpys reshape (eg. matrix.reshape(9,260,745) or any other combination of 9,260,745) it doesn't yield the required structure since the above mentioned ordering is lost... Did I misunderstand the reshape method or can it be done this way? What other pythonic/numpy way is there to do this?

  • Zend - Deny access to CSS, JS, Image files

    - by Vincent
    All, I have the following Zend application structure: helloworld - application - configs - controllers - models - layouts - include - library - public - design -- css -- site.css -- js -- global.js -- images -- siteheader.gif -- sitefooter.gif - .htaccess - index.php My .htaccess file in public folder looks like this: Options -MultiViews RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] My document root points to the "public" folder. Currently, if the user visits a directory level URL, (Ex: http://localhost/design or localhost/css) , my .htaccess file above make sure to show him the "Access Forbidden" page. But if he visits the file level URL, (Ex: http://localhost/design/css/site.css), it shows him the CSS file or the js file or PHP file.. How can I make sure to lock file level access for the above file types, if accessed directly from the URL? Since my application is JS intensive, I want to protect it from users looking at it. Thanks

  • C++ -- How can we call "delete this; " in a const-member function?

    - by q0987
    Hello all, I saw the code snippet as follows: class UPNumber { public: UPNumber(); UPNumber(int initValue); ... // pseudo-destructor (a const member function, because // even const objects may be destroyed) void destroy() const { delete this; } // why this line is correct??? ... private: ~UPNumber(); }; First, I am sure that above class definition is correct. Here is my question, why we can define the function 'destroy' as above? The reason being asking is that why we can modify 'this' in a const-member function? Thank you

    - by Omky
    Hello Geeks, I am developing some tool for BI. There are terms like Fact, Dimensions and Measures. My application will connect to the normal database and read the data from that table.

  • Need Help with Page Life Cycle(I think it is screwing me up)

    - by chobo2
    Hi I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those. Now my table gets filled up and has dropdown lists. When the user hits save I go through all the rows and update the values from the dropdownlist in the db. This works all great. However if 2 columns have each have "Present" then those 2 columns should be not be shown anymore and 2 new columns get put in its place with other dropdown lists. This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away. So what I tried to do is at the end of the button click event. Clear the whole table and then regenerate it. However when I do this then my values are not saved to the database anymore for whatever reason. if (IsPostBack == false) { // check if dummy variables exist in db- If true just generate tables with values in db. If not generate them. } else { // grab the values from the database // generate tables with the values } btn click event { go through all rows in table(foreach loop) update each column in the database with cells in each row. while in foreach loop. //done } So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user. Does not work if (IsPostBack == false) { // same code as above } // if postback is true do nothing. By the time it gets to the click event it says there is zero rows in the table so nothing happens. btn click event { // same code } Fails also. if (IsPostBack == false) { // same code as above } else { // same code as above but moved into its own method. gernerateTable(); } btn click event { // update all rows // once done clear the Tables rows // call generateTable() } This last one does nothing as for some reason it does not update anything. I don't understand why. So what am I doing wrong with this life cycle something in my process is wrong. The code works just not when I want the table to be updated right away.

Uniformed Search: search for a file under UNIX directoy. A* Search: search a way (staring from home) to go to mulitple stores to buy things then get back home with minimum total travelling time. MinMax:Go or other Chess. Please correct me if I am wrong.

  • Mod_Rewrite: Insert "/" between variables and values in URL

    - by Abs
    Hello all, I am attempting clean useful URLs using mod_rewrite. I am sure this is a common question but I am not so hot with mod_rewrite: I have this URL: http://mysite.com/user.php?user=fatcatmat&sort=popularv I want to be able to rewrite it like this: http://mysite.com/user/user/fatcatmat/sort/popularv (Is there a way to remove duplicates in a URL?) I think I have managed to do the removal of the PHP extension. RewriteRule ^(.*)\$ $1.php [nc] Is the above correct? For the separate pages, I would have something like this. RewriteRule ^/?user(/)?$ user.php Main Question: Its a bit tedious to do all the above but is there a MEGA rewrite rule that will just place "/" in between variables and their values and remove the .php extension from all pages? Thank you for any help.

  • BASH Expression to replace beginning and ending of a string in one operation?

    - by swestrup
    Here's a simple problem that's been bugging me for some time. I often find I have a number of input files in some directory, and I want to construct output file names by replacing beginning and ending portions. For example, given this: source/foo.c source/bar.c source/foo_bar.c I often end up writing BASH expressions like: for f in source/*.c; do a="obj/${f##*/}" b="${a%.*}.obj" process "$f" "$b" done to generate the commands process "source/foo.c" "obj/foo.obj" process "source/bar.c "obj/bar.obj" process "source/foo_bar.c "obj/foo_bar.obj" The above works, but its a lot wordier than I like, and I would prefer to avoid the temporary variables. Ideally there would be some command that could replace the beginning and ends of a string in one shot, so that I could just write something like: for f in source/*.c; do process "$f" "obj/${f##*/%.*}.obj"; done Of course, the above doesn't work. Does anyone know something that will? I'm just trying to save myself some typing here.

  • Reuse C++ Header files

    - by Amrish
    Guys, I have a Visual C++ solution with 2 projects AlgorithmA & AlgorithmB and both share a common header file RunAlgo.h with the class declaration. Each project in the solution has its own unique implementation for the header file. I am trying to compile a DLL out of the common header file RunAlgo.h and add reference to this DLL in the projects AlgorithmA & AlgorithmB. I have then included separate RunAlgo.cpp definition file in both my projects. The problem is that I am getting linker errors while compiling the new DLL project which has only the header file. So, the question is Can a header file with only class declaration be compiled into a DLL (Similar to class library containing an Interface in C#)? For the above scenario, is there a better approach to reuse the common Header file among projects? Should the above method work (re-check my code?)

  • process incoming mail and parse out original text

    - by florin
    I have inherited a rails forum (Rails 2.3.2 I think) that alerts people of new posts/replies for the forums or threads they are watching. To make it easier for people to answer to threads I would like to enable reply-to-post, similar to basecamp and a bunch of other forums and tools out there. I would add a separator text (like "----add your reply above this line-----") in the original email. I need to: - process incoming email - extract the new text (above the separator line) - ideally strip out text like "on ... [email protected] wrote:" that is automatically added by some mail clients - identify the thread this email is referring to (either using the incoming address or the subject line) - identify the sender - post the content as new reply Any suggestions on how to get started? Any good plugins for this? I've seen many mentioning Mailman and Fetcher, are there any other and which one is the best for this little feature? Thanks!

  • F# powerpack and distribution

    - by rwallace
    I need arbitrary precision rational numbers, which I'm given to understand are available in the F# powerpack. My question is about the mechanics of distribution; my program needs to be able to compile and run both on Windows/.Net and Linux/Mono at least, since I have potential users on both platforms. As I understand it, the best procedure is: Download the powerpack .zip, not the installer. Copy the DLL into my program directory. Copy the accompanying license file into my program directory, to make sure everything is above board. Declare references and go ahead and use the functions I need. Ship the above files along with my source and binary, and since the DLL uses byte code, it will work fine on any platform. Is this the correct procedure? Am I missing anything?

  • Parse Domain from a given URL in T-SQL

    - by Adam N
    I fount this answer, but wanted to expand on the question and couldn't find any solutions here on stack or through searching google. Substring domainname from URL SQL Basically the link above solves my problem with a simple URL like parsing "www.google.com" with the result of google. What I am looking for to expand on that is the solution from the link above doesn't help with url's like 'www.maps.google.com' that just returns maps. WHat I would like is to have it return 'google' from the url 'www.maps.google.com' or return 'example' from 'www.test.example.com'. If anyone has a solution to this, I would greatly appreciate it. Update: To be more specific I will also need parsing on second level domains etc. 'www.maps.google.com.au' to return 'google' Here is my Sql function. CREATE FUNCTION [dbo].[parseURL] (@strURL varchar(1000)) RETURNS varchar(1000) AS BEGIN IF CHARINDEX('.', REPLACE(@strURL, 'www.','')) > 0 SELECT @strURL = LEFT(REPLACE(@strURL, 'www.',''), CHARINDEX('.',REPLACE(@strURL, 'www.',''))-1) Else SELECT @strURL = REPLACE(@strURL, 'www.','') RETURN @strURL END

  • Linq Query - Average Time (DateTime data types)

    I have a database that has the following records in a DateTime field: 2012-04-13 08:31:00.000 2012-04-12 07:53:00.000 2012-04-11 07:59:00.000 2012-04-10 08:16:00.000 2012-04-09 15:11:00.000 2012-04-08 08:28:00.000 2012-04-06 08:26:00.000 I want to run a linq to sql query to get the average time from the records above. I tried the following: (From o In MYDATA Select o.SleepTo).Average() Since "SleepTo" is a datetime field I get an error on Average(). If I was trying to get the average of say an integer, the above linq query works. What do I need to do to get it to work for datetimes?

  • The easiest way to draw an image?

    - by Benno
    Assume you want to read an image file in a common file format from the hard drive, change the color of one pixel, and display the resulting image to the screen, in C++. Which (open-source) libraries would you recommend to accomplish the above with the least amount of code? Alternatively, which libraries would do the above in the most elegant way possible? A bit of background: I have been reading a lot of computer graphics literature recently, and there are lots of relatively easy, pixel-based algorithms which I'd like to implement. However, while the algorithm itself would usually be straightforward to implement, the necessary amount of frame-work to manipulate an image on a per-pixel basis and display the result stopped me from doing it.

  • Automatically create valid links

    - by Marcos Placona
    Hi, I'm new to python, so please bare with me :) I was wondering if there's any built-in way in python to append variables to URL's regardless of it's structure. I would like to have a URL variable (test=1) added to an URL which could have any of the following structures http://www.aaa.com (would simply add "/?test=1") to the end http://www.aaa.com/home (like the one above, would simply add "/?test=1") to the end http://www.aaa.com/?location=home (would figure out there's already a ? being used, and would add &test=1 to the end) http://www.aaa.com/?location=home&page=1 (like the one above, would figure out there's already a ? being used, and would add &test=1 to the end) I'd be happy to write domething to do it myself, but if python can already do it somehow, I'd me more than happy to use any built-in functionality that would save me some time ;-) Thanks in advance
