• PHP Regex Question

  - by oyerli

  Hi, I am developing an application using PHP but I am new to regular expressions, I could not find a solution to my problem. I want to replace all occurences of #word with a link, i have written a preg_match for this: $text=preg_replace('~#([\p{L}|\p{N}]+)~u', '<a href="/?aranan=$1">#$1</a>', $text); The problem is, this regular expression also matches the html character codes like &#039; and gives corrupt output. I need to exclude the words starting with &# but i do not know how to do that using regular expressions. Thanks for your help.

• Calculate open timeslots given availability and existing appointments - by day

  - by Andre

  Overview: I have a table which stores a persons "availability" for a current day, e.g. Mon - 8:00am - 11:30am Mon - 1:30pm - 6:00pm A second table stores appointments that this person already has for the same day, e.g. Mon - 8:30am - 11:00am Mon - 2:30pm - 4pm Desired result: Doing calculationsI'd like to have the following result - e.g. "this person has availability on the given day": Mon - 8:00am - 8:30am Mon - 11:00am - 11:30am Mon - 1:30pm - 2:30pm Mon - 4:00pm - 6:00pm Any ideas on how to calculate the output given the two inputs (e.g. availability, existing appointments) would be greatly appreciated. Preferably I'd use javascript on the client to do the calculating as I would believe that doing it within the DB (I'm using MSSQL) would be slow for many records, persons, etc. Hope this is enough information to illustrate the problem at hand - Many thanks in advance.

  - by Labeeb P

  Hi, I have made two folders, res/layout and res/layout-land The output i got If I start the application in portrait mode, it will always use the xml in layout folder if the application run in portrait mode. And will not use xml in layout-land if i change the device to landscape mode If it start in landscape mode it only use the xml in layout-land The xml is not switching when the orientation change What i expect was It should use the xml in layout folder while it is in portrait mode and use the xml in layout-land while in landscape mode In the Manifest file i have added android:configChanges="orientation" for the activity and <supports-screens android:resizeable="true" android:largeScreens="true" android:normalScreens="true" android:anyDensity="true" /> Did i missed any thing here?

• Constructor return value

  - by Ivan Gromov

  Could you tell me what is wrong with my class constructor?

• Is my code really not unit-testable?

  - by John

  A lot of code in a current project is directly related to displaying things using a 3rd-party 3D rendering engine. As such, it's easy to say "this is a special case, you can't unit test it". But I wonder if this is a valid excuse... it's easy to think "I am special" but rarely actually the case. Are there types of code which are genuinely not suited for unit-testing? By suitable, I mean "without it taking longer to figure out how to write the test than is worth the effort"... dealing with a ton of 3D math/rendering it could take a lot of work to prove the output of a function is correct compared with just looking at the rendered graphics.

• Can you reuse a mysql result set in PHP?

  - by MarathonStudios

  I have a result set I pull from a large database: $result = mysql_query($sql); I loop through this recordset once to pull specific bits of data and get averages using while($row = mysql_fetch_array($result)). Later in the page, I want to loop through this same recordset again and output everything - but because I used the recordset earlier, my second loop returns nothing. I finally hacked around this by looping through a second identical recordset ($result2 = mysql_query($sql);), but I hate to make the same SQL call twice. Any way I can loop through the same dataset multiple times?

• Uniform distribution of binary values in Matlab

  - by JohnIdol

  I have a requirement for the generation of a given number N of vectors of given size each consistent of a uniform distribution of 0s and 1s. This is what I am doing at the moment, but I noticed that the distribution is strongly peaked at half 1s and half 0s, which is no good for what I am doing: a = randint(1, sizeOfVector, [0 1]); The unifrnd function looks promising for what I need, but I can't manage to understand how to output a binary vector of that size. Is it the case that I can use the unifrnd function (and if so how would be appreciated!) or can is there any other more convenient way to obtain such a set of vectors? Any help appreciated!

• Routing Error in Chapter 7.1.2 of the Ruby on Rails Tutorial

  - by user2985910

  I've been working through the tutorial for the past few days, and finally hit a snag in chapter 7. It is in this step where the line in routes.rb: get "users/new" is replaced with resource :users After I do this, I get a routing error when visiting http://localhost:3000/users/1 - No route matches [GET] "/users/1" instead of the other "Unknown Action" error shown here. Per the instructions, my routes.db file looks like this: SampleApp::Application.routes.draw do resource :users root "static_pages#home" match '/signup', to: 'users#new', via: 'get' match '/help', to: 'static_pages#help', via: 'get' match '/about', to: 'static_pages#about', via: 'get' match '/contact', to: 'static_pages#contact', via: 'get' end Output from 'rake routes' shows: Prefix Verb URI Pattern Controller#Action users POST /users(.:format) users#create new_users GET /users/new(.:format) users#new edit_users GET /users/edit(.:format) users#edit GET /users(.:format) users#show PATCH /users(.:format) users#update PUT /users(.:format) users#update DELETE /users(.:format) users#destroy root GET / static_pages#home signup GET /signup(.:format) users#new help GET /help(.:format) static_pages#help about GET /about(.:format) static_pages#about contact GET /contact(.:format) static_pages#contact Does anyone have any insight to get past this?

• Stealing the contents of another application's tree view

  - by User1

  I have an application with a very large TreeView control in Java. I want to get the contents of the tree control in a list (just strings not a JList) of XPath-like elements of leaves only. Here's an example root |-Item1 |-Item1.1 |-Item1.1.1 (leaf) |-Item1.2 (leaf) |-Item2 |-Item2.1 (leaf) Would output: /Item1/Item1.1/Item1.1.1 /Item1/Item1.2 /Item2/Item2.1 I don't have any source code or anything handy like that. Is there I tool I can use to dig into the Window item itself and pull out this data? I don't mind if there are a few post-processing steps because typing it in by hand is my only other option.

• PHP: Regular Expression to get a URL from a string

  - by Matthew Iselin

  I'm working on some PHP code which takes input from various sources and needs to find the URLs and save them somewhere. The kind of input that needs to be handled is as follows: http://www.youtube.com/watch?v=IY2j_GPIqRA Try google: http://google.com! (note exclamation mark is not part of the URL) Is http://somesite.com/ down for anyone else? Output: http://www.youtube.com/watch?v=IY2j_GPIqRA http://google.com http://somesite.com/ I've already borrowed one regular expression from the internet which works, but unfortunately wipes the query string out - not good! Any help putting together a regular expression, or perhaps another solution to this problem, would be appreciated.

• identify documents from results of mahout clustering

  - by Tejas

  I am using mahout to cluster text documents indexed using solr. I have used the "text" field in the document to form vectors. Then I used the k-means driver in mahout for clustering and then the clusterdumper utility to dump the results. I am having difficulty in understanding the output results from the dumper. I could see the clusters formed with term vectors in those clusters. But how do I extract the documents from these clusters. I want the result to be the input documents appearing in different clusters.

• Java file delete on NFS drive

  - by RenegadeAndy

  Hey guys. I am trying to delete a file on a NFS drive. I have had other problems manipulating files on remote drives such as moving a file - however i got around it by not using the conventional method i.e renameFile but instead properly using input and output streams. However using the File.delete() returns false , and I have heard suggestions on using the apache commons io FileUtils class - however it just throws an IO exception. Does anybody have any suggestions on a way to delete a file on a network mounted drive using java? Thanks

• MSBuild syntax for deleting files/directories and reporting what was deleted

  Vs2010 .net 4.0 targeted project if that affects the answers at all. I want to delete the bin and obj directories and output a message for the path of what was deleted. <Target Name="CleanOutputs" Condition="'$(MvcBuildViews)'=='true'"> <Message Text="Cleaning Outputs" Importance="high"/> <RemoveDir Directories="$(OutputPath);obj" RemovedDirectories="@(removed)" /> <Message Text="Removed: %(removed.FullPath)" Importance="high"/> <Message Text=" "/> <!--<RemoveDir Directories="obj" />--> <MakeDir Condition="!Exists('$(OutputPath)')" Directories="$(OutputPath)" /> </Target> Is what I have, but the Removed: message never shows.

• R: how to make a unique set of names from a vector of strings?

  - by Mike Dewar

  Hi, I have a vector of strings. Check out my vector, it's awesome: > awesome [1] "a" "b" "c" "d" "d" "e" "f" "f" I'd like to make a new vector that is the same length as awesome but where, if necessary, the strings have been uniqueified. For example, a valid output of my desired function would be > awesome.uniqueified [1] "a" "b" "c" "d.1" "d.2" "e" "f.1" "f.2" Is there an easy, R-thonic and beautiful way to do this? I should say my list in real life (it's not called awesome) contains 25000ish mircoarray probeset identifiers. I'm always nervous when I embark on writing little generic functions (which I'm sure I could do) as I'm sure some R guru has come across this problem in the past, nailed it with some incredible algorithm that doesn't even have to store more than half an element in the vector. I'm just not sure what they might have called it. Probably not uniqueify.

• I need to do a BASICE For Loop algorithm for a java Pyramid

  - by user1665119

  Question 2. USE THE FOR LOOP. Design and write an algorithm that will read a single positive number from the keyboard and will then print a pyramid out on the screen. The pyramid will need to be of a height equal in lines to the number inputted by the operator. Your program is not to test for negative numbers, nor is it to cater for them. For your test, use the number 7. If you would like to take the problem further, try 18 and watch what happens. Example input: 4 Example output: 1 121 12321 1234321

• phpunit - generate tests for all the classes from a directory

  - by joe

  Hi! I have a directoy structure, and all the classes of the business logic are placed in the app_dir/lib/ directory. I would like to generate unit tests for all the classes from this lib/ folder. The problem is, that I haven't found any option to specify the source directory, only the source file: from app_dir: phpunit --skeleton-class lib/ Error: "lib/.php" could not be opened. Is it the only solution to write my own php script, which iterates through the /lib folder and calls the skeleton generator for every file found? And how can I specify the output folder, where all the generated test files are placed? Thanx, Joe

• Cannot find libmysqlclient under /usr. while build PHP 5.2 from source on Ubuntu 12.4

  - by fkniya

  I was trying to build PHP 5.2.17 from source on Ubuntu 12.4 64bit using this configuration: ./configure --prefix=/opt/php5.2 --with-config-file-path=/opt/php5.2 --with-mysql but I keep getting this error: configure: error: Cannot find libmysqlclient under /usr. Note that the MySQL client library is not bundled anymore! I suspected that dev package for mysql is not installed so tried installing libmysqlclient-dev but it was already there. Any Idea how to resolve this? EDIT1: I minimized the configure command so it just focuses to mysql. also I'm running a 64bit version of ubuntu. EDIT2: tried running ldconfig -v |grep mysql and here is the output # ldconfig -v |grep mysql /sbin/ldconfig.real: Path `/lib/x86_64-linux-gnu' given more than once /sbin/ldconfig.real: Path `/usr/lib/x86_64-linux-gnu' given more than once /sbin/ldconfig.real: Cannot stat /usr/lib/x86_64-linux-gnu/libnss_db.so: No such file or directory libmysqlclient.so.18 -> libmysqlclient_r.so.18.0.0 libmysqlpp.so.3 -> libmysqlpp.so.3.1.0

• Custom Brush - I want two gradients chaining them together.

  - by Logan

  I am making a bar chart and I want two separate gradients for each bar. First I want a gradient to go from top to bottom solid red to transparent red. I want to paint over the top of that a gradient that goes from right to left, black to opaque. So - In the bottom left we should have; Bottom left - Alpha 0 Bottom right - Alpha 0 Top left - Alpha 255 Colour Red Top Right - Alpha 255 Colour Black So in effect I want to take a solid colour, add a left to right gradient to black then take the output of that and add a top to bottom gradient to transparency. All this and I want it to be in a single brush, is this even possible?

• Does JSLint parse DOM functions?

  - by Paul

  I tried to use the parse() function of JSLint to parse three pieces of JavaScript code: function(b, c){var a = b + c; return a; } window.addEventListener('click', click_hanlder, true); document.documentElement.innerHTML; Here's the code, which is copied and pasted from the JSLint self-parse example: ` try { parse = make_parse(); var source = "something to parse";//replaced by the code above tree = parse(source); if (tree) { document.write(JSON.stringify(tree, ['key', 'name', 'message', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } } catch (e) { document.write(JSON.stringify(e, ['name', 'message', 'from', 'to', 'key', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } ` The output: returns a correct tree. returns a tree with only one node of "window". crashes the browser. I'm wondering whether JSLint doesn't support DOM function.

• C# StandardInput Sending Mofidiers

  - by Paul Oakham

  Hi All, We have some legacy software which depends on sending keystrokes to a DOS window and then scraping the screen. I am trying to re-create the software by redirecting the input and output streams of the process directly to my application. This part I have managed fine using: _Process = new Process(); { _Process.StartInfo.FileName = APPLICATION; _Process.StartInfo.RedirectStandardOutput = true; _Process.StartInfo.RedirectStandardInput = true; _Process.StartInfo.RedirectStandardError = true; _Process.StartInfo.UseShellExecute = false; _Process.StartInfo.CreateNoWindow = true; _Process.OutputDataReceived += new DataReceivedEventHandler(_Process_OutputDataReceived); _Process.ErrorDataReceived += new DataReceivedEventHandler(_Process_ErrorDataReceived); } My problem is I need to send some command modifiers such as Ctrl, ALT and Space as well as F1-12 to this process but am unsure how. I can send basic text and I receive response's fine. I just need to emulate these modifiers. Any help would be great, Cheers

• vb.net auto detect dependency files for wix 3.7

  - by Khan

  I am in the process of learning WIX all thanks to MS for removing such a nice tool (vdproj) from the latest versions of visual studio. I have come to know that I can add my files (and dlls) to distribute in WIX using that tag. It is OK. But in vdproj it was very easy to add all files. I just need to right click in file view, and select 'add project output'. This was enough to add dozen of files that were required for my application. In visual studio 2012, and using WIX 3.7, what options do I have to automatically list all those dlls that are required by my application?
