• Pull datasets from DB and manipulate into separate arrays

  - by dresdin

  My DB has four fields, date:date, morning:integer, afternoon:integer, evening:integer. Google charts needs the data split into one array per dataset (example below). What's the best way to do this? ['Day', 'Morning', 'Afternoon', 'Evening'], ['06/27/13', 1000, 400 234], ['06/28/13', 1170, 460 275], ['06/29/13', 660, 1120 377], ['06/30/13', 1030, 540 934] I've tried this without much luck: var data = google.visualization.arrayToDataTable([ <% @todo.each do |t| %> ['Day', 'Morning', 'Afternoon', 'Evening'], [<%= t.date.strftime("%m/%d/%y") %>, <%= t.morning %>, <%= t.afternoon %>, <%= t.evening %>] <% end %> ]);

• How can one put together multiple arrays into one string?

  - by Noor

  I'm having a hard time describing what I'm looking for. If we pretend that we're pulling an array (I've used the .split to get user input data) where each line represents a link. How can I then add an anchor tagg to that link that I'm pulling? I need to be able to put < a href=" + thearray + "anything< /a. The reason for this is that I'm dynamically creating a list. I think that if I create two variables, one with this part < a href=" one with the closing and then call some sort of function that puts those two and the pulled array in between them until the list is complete. Does this make any sense?

• php: ip2long returning negative val

  - by andufo

  hi, function ip_address_to_number($IPaddress) { if(!$IPaddress) { return false; } else { $ips = split('\.',$IPaddress); return($ips[3] + $ips[2]*256 + $ips[1]*65536 + $ips[0]*16777216); } } that function executes the same code as the php bundled function ip2long. however, when i print these 2 values, i get 2 different returns. why? (im using php 5.2.10 on a wamp environment). ip2long('200.117.248.17'); //returns -931792879 ip_address_to_number('200.117.248.17'); // returns 3363174417

• JBoss classloading when 2 WARs have the same class

  - by Pacman

  I have a web applications A.war which has two servlets AServlet and BServlet. Both instantiate a helper class com.mycompany.Foo.class (this is my own class, not a third party library). Now I want to split the two servlets into two separate WARs: A.war will have only AServlet and a new B.war will have BServlet. AServlet will invoke BServlet via HTTP GET. Both WARs will have com.mycompany.Foo.class. I want to deploy both WARs on the same JBoss instance. The question is, will there be any classloading issues due to the same class being present in both WARs, and the WARs being deployed on the same JBoss instance?

• Strategy to structure a search index in a relational database

  - by neilc

  I am interested in suggestions for building an efficient and robust structure for indexing products in a new database I am building (i'm using MySql) When a product is entered through the form there are three parts I am interested in indexing for searching purposes. The product title The product description Tags The most important is title, followed by tags, followed by the description. I was thinking of using the following structure CREATE TABLE `searchindex` ( `id` INT NOT NULL , `word` VARCHAR( 255 ) NOT NULL , `weighting` INT NOT NULL , `product_id` INT NOT NULL , PRIMARY KEY ( `id` ) ) Then each time a product is created I would split apart the title, description and tags (removing common words) and award them a weighting. Then it is trivial to select out the words and corresponding products and order them by weighting. Is there a better way to do this? I would be worried that this strategy would slow down over time and as the database filled up.

• Vbscript - Checking each subfolder for files

  - by Kenny Bones

  Ok, this is a script that's supposed to basically mirror two sets of folders. I managed to get it to work, but it seems like it didn't check each subfolder. So, I added these lines to the code: Set colFolders = objFolder.Subfolders Then I added this: For each subFolder in colFolders For each objFile in colFiles Dim DateModified DateModified = objFile.DateLastModified ReplaceIfNewer objFile, DateModified, strSourceFolder, strDestFolder Next Next This however does not seem to be working. This is the full code below. Dim strSourceFolder, strDestFolder Dim fso, objFolder, colFiles, colfolders strSourceFolder = "c:\users\vegsan\desktop\Source\" strDestFolder = "c:\users\vegsan\desktop\Dest\" Set fso = CreateObject("Scripting.FileSystemObject") Set objFolder = fso.GetFolder(strSourceFolder) Set colFiles = objFolder.Files Set colFolders = objFolder.Subfolders For each subFolder in colFolders For each objFile in colFiles Dim DateModified DateModified = objFile.DateLastModified ReplaceIfNewer objFile, DateModified, strSourceFolder, strDestFolder Next Next Sub ReplaceIfNewer (sourceFile, DateModified, SourceFolder, DestFolder) Const OVERWRITE_EXISTING = True Dim fso, objFolder, colFiles, sourceFileName, destFileName Dim DestDateModified, objDestFile Set fso = CreateObject("Scripting.FileSystemObject") sourceFileName = fso.GetFileName(sourceFile) destFileName = DestFolder & sourceFileName if fso.FileExists(destFileName) Then Set objDestFile = fso.GetFile(destFileName) DestDateModified = objDestFile.DateLastModified if DateModified <> DestDateModified Then fso.CopyFile sourceFile, destFileName End if End if if Not fso.FileExists(destFileName) Then fso.CopyFile sourceFile, destFileName End if End Sub

• How to allow for modular development while still running in same JVM?

  - by Marcus

  Our current app runs in a single JVM. We are now splitting up the app into separate logical services where each service runs in its own JVM. The split is being done to allow a single service to be modified and deployed without impacting the entire system. This reduces the need to QA the entire system - just need to QA the interaction with the service being changed. For interservice communication we use a combination of REST, an MQ system bus, and database views. What I don't like about this: REST means we have to marshal data to/from XML DB views couple the systems together which defeats the whole concept of separate services MQ / system bus is added complexity There is inevitably some code duplication between services You have set up n JBoss server configurations, we have to do n number of deployments, n number of set up scripts, etc, etc. Is there a better way to structure an internal application to allow modular development and deployment while allowing the app to run in a single JVM (and achieving the associated benefits)?

• Search for a String and replace it with a variable

  - by chrissygormley

  Hello, I am trying to use regular expression to search a document fo a UUID number and replace the end of it with a new number. The code I have so far is: read_file = open('test.txt', 'r+') write_file = open('test.txt', 'w') r = re.compile(r'(self.uid\s*=\s*5EFF837F-EFC2-4c32-A3D4\s*)(\S+)') for l in read_file: m1 = r.match(l) if m1: new=(str,m1.group(2)) new?????? This where I get stuck. The file test.txt has the below UUID stored in it: self.uid = '5EFF837F-EFC2-4c32-A3D4-D15C7F9E1F22' I want to replace the part D15C7F9E1F22. I have also tried this: r = re.compile(r'(self.uid\s*=\s*)(\S+)') for l in fp: m1 = r.match(l) new=map(int,m1.group(2).split("-") new[4]='RHUI5345JO' But I cannot seem to match the string. Thanks in advance for any help.

• Are indivisible operations still indivisible on multiprocessor and multicore systems?

  - by Steve314

  As per the title, plus what are the limitations and gotchas. For example, on x86 processors, alignment for most data types is optional - an optimisation rather than a requirement. That means that a pointer may be stored at an unaligned address, which in turn means that pointer might be split over a cache page boundary. Obviously this could be done if you work hard enough on any processor (picking out particular bytes etc), but not in a way where you'd still expect the write operation to be indivisible. I seriously doubt that a multicore processor can ensure that other cores can guarantee a consistent all-before or all-after view of a written pointer in this unaligned-write-crossing-a-page-boundary situation. Am I right? And are there any similar gotchas I haven't thought of?

• Optimize conditional operators branching in C#

  - by abatishchev

  Hello. I have next code: return this.AllowChooseAny.Value ? radioSpecific.Checked ? UserManager.CurrentUser.IsClient ? txtSubject.Text : subjectDropDownList.SelectedItem.Text : String.Empty : UserManager.CurrentUser.IsClient ? txtSubject.Text : subjectDropDownList.SelectedItem.Text; or in less complex form: return any ? specified ? isClient ? textbox : dropdown : empty : isClient ? textbox : dropdown; or in schematic form: | any / \ specified isClient / \ / \ isClient empty textbox dropdown / \ textbox dropdown Evidently I have a duplicated block on two different levels. Is it possible to optimize this code to probably split them to one? Or something like that..

• How to keep code maintainable after original programmer quit

  - by Stan

  Say if it's a 10 people project, 2-3 of the original programmer quit after the project has been release a stable version for a while. How to have the code maintainable in this case? My imagination is reviewing the code after the project goes to release version and keep review it afterwards? Maybe split into 2-3 small groups and have each group review part of the code. So at least 3-4 people are familiar with part of code. Does this work? How do companies deal with this issue? Usually how many percentage of time spent on reviewing the code? Please advise, thanks to community.

• PHP or C# script to parse CSV table values to fill in one-to-many table

  - by Yaaqov

  I'm looking for an example of how to split-out comma-delimited data in a field of one table, and fill in a second table with those individual elements, in order to make a one-to-many relational database schema. This is probably really simple, but let me give an example: I'll start with everything in one table, Widgets, which has a "state" field to contain states that have that widget: Table: WIDGET =============================== | id | unit | states | =============================== |1 | abc | AL,AK,CA | ------------------------------- |2 | lmn | VA,NC,SC,GA,FL | ------------------------------- |3 | xyz | KY | =============================== Now, what I'd like to create via code is a second table to be joined to WIDGET called *Widget_ST* that has widget id, widget state id, and widget state name fields, for example Table: WIDGET_ST ============================== | w_id | w_st_id | w_st_name | ------------------------------ |1 | 1 | AL | |1 | 2 | AK | |1 | 3 | CA | |2 | 1 | VA | |2 | 2 | NC | |2 | 1 | SC | |2 | 2 | GA | |2 | 1 | FL | |3 | 1 | KY | ============================== I am learning C# and PHP, so responses in either language would be great. Thanks.

• Target not being executed when imported to the main *.proj file

  - by Zbigniew Kawalec

  I use the TFS 2008 build facilities. I have a large MSBuild project (TFSBuild.proj) and I wanted to split it into a few files because it is becoming hard to maintain. I found a strange behavior; when I extracted one of the targets (BeforeInitializeWorkspace) to a separate file and then imported it into the main *.proj file, it was not executed. Although, in my MSBuild log, there was information that the target has been imported and overridden, but hasn't been executed. If I have the same target defined in my main *.proj file, it is executed. Can someone explain why the target isn't executed when imported from a file? Thanks,

• Avoid hourglass mouse cursor when calling a web-service?

  - by BigMoose

  I don't know if this is a general web-services issue or just my specific scenario, which is a WPF application with a DispatcherTimer calling a web-service method. Whenever the timer is called, the mouse cursor automatically changes to an hourglass cursor. The processing of the call is very short and happens every 3 seconds, so the user experience is that every 3 seconds the mouse filckers as an hourglass for a split-second and then goes back to the normal cursor representation. How can I avoid this inconvenience? Thanks.

• Which SOA architecture is most appropriate for a Java application?

  - by Robert Greiner

  I am currently working on a pretty large Java 6 application where we are looking to split some of our functionality out into a service oriented architecture. It seems that the primary SOA framework for the application space is OSGi and I have been looking into Felix and Knopplerfish but I wanted to make sure that this isn't my only option. Does it make sense to use an actual web service protocol for our application like SOAP, even though we are not building a web app? Is this even acceptable? Have any of you used an implementation of OSGi (Felix, etc.) with your desktop application? if so, how did it go? Do you know of anything better? We're all pretty new to SOA here so any help would be greatly appreciated.

• PowerShell: Read text, regex sort, write output to file and formatting

  - by Bill Hunter

  I am a Powershell novice and have run into a challenge in reading, sorting, and outputting a csv file. The input csv has no headers, the data is as follows: 05/25/2010,18:48:33,Stop,a1usak,10.128.212.212 05/25/2010,18:48:36,Start,q2uhal,10.136.198.231 05/25/2010,18:48:09,Stop,s0upxb,10.136.198.231 I use the following piping construct to read the file, sort and output to a file: (Get-Content d:\vpnData\u62gvpn2.csv) | %{,[regex]::Split($, ",")} | sort @{Expression={$[3]}},@{Expression={$_[1]}} | out-file d:\vpnData\u62gvpn3.csv The new file is written with the following format: 05/25/2010 07:41:57 Stop a0uaar 10.128.196.160 05/25/2010 12:24:24 Start a0uaar 10.136.199.51 05/25/2010 20:00:56 Stop a0uaar 10.136.199.51 What I would like to see in the output file is a similar format to the original input file with comma dilimiters: 05/25/2010,07:41:57,Stop,a0uaar,10.128.196.160 05/25/2010,12:24:24,Start,a0uaar,10.136.199.51 05/25/2010,20:00:56,Stop,a0uaar,10.136.199.51 But I can't quite seem to get there. I'm almost of the mind that I'll have to write another segment to read the newly produced file and reset its contents to the preferred format for further processing. Thoughts?

• Is it possible to join these two regex expressions into one?

  - by Pure.Krome

  Hi folks, i have the following two regular expressions (in order btw). 1. ^~/buying/(.*)\?(.*) => foo= group 1 baa= group 2. 2. ^~/buying/(.*) => foo= group 1 baa= nothing/empty/null/baibai What's i'm trying to do is, if the url has a questionmark, then split it into two groups. Otherwise, just throw all the stuff into the first group. the reason why the order is important for me, is that if i switch them round, the '?' regex will never get fired because the #2 expression (above) will catch all. So .. can this be re-fixed? NOTE: I have tried using this website** to help me debug/tweak .. but I can't figure it out. ** I have no affiliation with that site.

• Lines-of-code counting for many C# solutions

  - by Eric

  I am currently researching a solution for counting lines of code in C#. I pretty much need a combination of the following two tools: http://richnewman.wordpress.com/2007/07/01/c-and-vbnet-line-count-utility/ http://www.locmetrics.com/index.html My problem is that I need to recursively scan a folder containing a lot of visual studio solutions. So can't really use the first tool without any major work on its code, as it's only able to scan a single solution at a time. But I also need to split the results for each solution, preferably even the contained projects. This disqualifies the second tool I found. I also found NDepend which suffers from the same problem. Do you know of any free tools that do what I need? I am unable to find anything suitable.
