• Branch structure for a web site

  - by steve_d

  I was recently reading the TFS Branching Guide and it suggests a branch for every release. For a web site, there is only one "version" released at a time. In that case is it appropriate to have a single "Production" branch? Then, during the process of preparing for a release, you merge changes from the Main branch into Production. (As opposed to the suggestion to branch each release.) If you need to do a hotfix, do it in the Production branch, then reverse integrate into Main. Doing it this way allows you to keep configuration files for Production intact in the Production branch.

• How can I select all records between two dates without using date fields?

  - by Hayden Bech

  Hi, I have a MySQL DB and I need to be able to store dates earlier then 1970 - in my case, as early as 0 AD and earlier too, so I need a custom way to store dates. I have thought to use this format: Year - int(6) | Month -int(2) | day - int (2) | time - time | AD tinyint (1) | mya - int (11) But when it comes to actually using data in this format it becomes difficult. For example, if I want to get all records between two dates it would be like (pseudocode not SQL): get all where year between minYear and maxYear if year == minYear, month = minMonth if year == maxYear, month <= maxMonth if month == minMonth, day = minDay if month == maxMonth, day <= maxDay if day == minDay, time = minTime if day == maxDay, time <= maxTime or something, which seems like a right pain. I could store seconds before/after 0 AD, but that would take up way too much data! 2010 (EDIT: 2011) = 6.4 billion seconds since 0 AD. Does anybody have any ideas for this problem?

• Using selector to change TextView text color

  - by rafuru

  I'm trying to use a TextView to define the style of a TabWidget on a tabhost. I just created a selector for bgcolor and works fine, but i want to make a selector for textColor but the text color don't change: This is my tab_text_selector.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_selected="true" android:color="@android:color/white" /> <item android:state_focused="true" android:color="@android:color/white" /> <item android:state_pressed="true" android:color="@android:color/white" /> </selector> And this is the code when i'm trying to use on a textView: TextView txtTab=new TextView(this); txtTab.setTextColor(R.drawable.tab_text_selector); txtTab.setBackgroundResource(R.drawable.tab_bg_selector); txtTab.setGravity(Gravity.CENTER); txtTab.setText("Agregar Idea"); I know the text color must be white in any case but it doesn't.

• Traversable => Java Iterator

  - by Andres

  I have a Traversable, and I want to make it into a Java Iterator. My problem is that I want everything to be lazily done. If I do .toIterator on the traversable, it eagerly produces the result, copies it into a List, and returns an iterator over the List. I'm sure I'm missing something simple here... Here is a small test case that shows what I mean: class Test extends Traversable[String] { def foreach[U](f : (String) => U) { f("1") f("2") f("3") throw new RuntimeException("Not lazy!") } } val a = new Test val iter = a.toIterator

• How can I share code across static libraries without duplicate symbol errors?

  - by Ben Flynn

  I am new to building static libraries and would like to create 2(+) libraries each of which has some unique code and some shared code. My intention is that other projects will link one or more of these static libraries. Util.h/m <-- Shared ImplOne.h/m <-- Unique to 'ImplOne' ImplTwo.h/m <-- Unique to 'ImplTwo' I am using XCode and generating the libraries by building Util.m and ImplOne.m in one case, and Util.m and ImplTwo.m in the other. Of course the issue is that I now cannot use these libraries together because they will have duplicate symbols. What is a better architecture for this situation?

• Java - Unknown characters passing as [a-zA-z0-9]*?

  - by Twodordan

  Hello, I'm no expert in regex but I need to parse some input I have no control over, and make sure I filter away any strings that don't have A-z and/or 0-9. When I run this, Pattern p = Pattern.compile("^[a-zA-Z0-9]*$"); //fixed typo if(!p.matcher(gottenData).matches()) System.out.println(someData); //someData contains gottenData certain spaces + an unknown symbol somehow slip through the filter (gottenData is the red rectangle): In case you're wondering, it DOES also display Text, it's not all like that. For now, I don't mind the [?] as long as it also contains some string along with it. Please help. [EDIT] as far as I can tell from the (very large) input, the [?]'s are either white spaces either nothing at all; maybe there's some sort of encoding issue, also perhaps something to do with #text nodes (input is xml)

• Output of System.out.println(object)

  - by Shaarad Dalvi

  I want to know what exactly the output tells when I do the following : class data { int a=5; } class main { public static void main(String[] args) { data dObj=new data(); System.out.println(dObj); } } I know it gives something related to object as the output in my case is data@1ae73783. I guess the '1ae73783' is a hex number. I also did some work around and printed System.out.println(dObj.hashCode()); I got number 415360643. I got an integer value. I don't know what hashCode() returns, still out of curiosity, when I converted 1ae73783 to decimal, I got 415360643! That's why I am curious that what exactly is this number?? Is this some memory location of Java's sandbox or some other thing? Any light on this matter will be helpful..thanks! :)

• When to use memberEnd and when navigableOwnedEnd (in Altova notation) in an UML class diagram?

  - by Ivan

  I've download a trial of Altova UModel and am starting using UML. As a practical beginning I am modelling a personal information manager application, which includes a web bookmark managing. A Bookmark can belong to many (or no) Tags at once and a Tag can contain many (or no if all the bookmarks it contained were deleted) bookmarks. The relation has to be both-way navigable - a user has to be able to see all Bookmarks with a particular Tags ans all Tags of a Bookmark. What is the correct UML relation between Bookmark and Tag classes? As far as I understand UML now, it is an Association (not an Aggregation). But for a 2-way navigable many-to-many relation I can specify ends roles as "memberEnd" or "when navigableOwnedEnd", graphically the connection looks the same in both cases (an arrow) (which as I understand means navigability) but a property appears in the class box in case only when "memberEnd" is used. How should I specif it in the model If I mean both-way navigable many-to-many relation there?

• Denormalize for Simplicity: Ungood idea?

  - by yar

  After reading this question, I've learned that denormalization is not a solution for simplicity. What about this case? I have news-articles which have a list of sites-article-will-be-published-to. The latter can be expressed in normalized fashion either by table and a many-to-many relationship (via a cross-table, I think). But the simple solution is to just throw a bunch of booleans for the sites-article-will-be-published-to. Assuming the sites are: small in number will not change over time have no fields themselves, except a name Is this still a terrible idea? The many-to-many relationship seems somewhat cumbersome, but I've done it before in cases like this (and it seemed cumbersome). Note: I'm doing this in Rails, where it's not that painful.

• create a dataset by using modulo division method

  - by ayoom

  create a dataset with 101 integers. Use the modulo division method of hashing to store the random data values into hash tables with table sizes of 7, 51, and 151. Use the linear probing and quadratic method of collision resolution. Print out the tables after the data values have been stored. Search for 10 different values in each of the three hash tables, counting the number of comparisons necessary. Print out the number of comparisons necessary in each case, in tabular form.

• parsing Two-dimensional array in c

  - by gitter78

  I'm trying to parse an array that looks like the one below: char *arr[][2] = { { "1", "Purple" }, { "2", "Blue" }, { "22", "Red" }, ... }; I was thinking having a loop as: char *func(char *a){ for(i = 0; i<sizeof(arr)/sizeof(arr[0]);i++){ if(strstr(a,arr[i][0])!=NULL) return arr[i][1]; } } char *out; const char *hello = "this is my 2 string"; out = func(hello); In this case, I'm trying to get the second value based on the first one: Purple, Blue Red, etc.. The question is how would go in parsing this and instead of printing out the value, return the value. UPDATE/FIXED: It has been fixed above. Thanks

• MPI Large Data all to all transfer

  - by csslayer

  My application of MPI has some process that generate some large data. Say we have N+1 process (one for master control, others are workers), each of worker processes generate large data, which is now simply write to normal file, named file1, file2, ..., fileN. The size of each file may be quite different. Now I need to send all fileM to rank M process to do the next job, So it's just like all to all data transfer. My problem is how should I use MPI API to send these files efficiently? I used to use windows share folder to transfer these before, but I think it's not a good idea. I have think about MPI_file and MPI_All_to_all, but these functions seems not to be so suitable for my case. Simple MPI_Send and MPI_Recv seems hard to be used because every process need to transfer large data, and I don't want to use distributed file system for now.

• Doesnt the Visual Studio 2008 compiler autocast to double with sqrt in C++?

  - by Chris_45

  Shouldn't the compiler automatically cast to a double in this case at least according to Walter Savitch: #include <iostream> #include <cmath> using namespace std; int main(){ int k; for(k = 1; k <= 10; k++) cout << "The square root of i is: " << sqrt(k) << endl; return 0; }//error C2668: 'sqrt' : ambiguous call to overloaded function //Visual Studio 2008 on Win Vista

• PHP Array Efficiency and Memory Clarification

  - by CogitoErgoSum

  When declaring an Array in PHP, the index's may be created out of order...I.e Array[1] = 1 Array[19] = 2 Array[4] = 3 My question. In creating an array like this, is the length 19 with nulls in between? If I attempted to get Array[3] would it come as undefined or throw an error? Also, how does this affect memory. Would the memory of 3 index's be taken up or 19? Also currently a developer wrote a script with 3 arrays FailedUpdates[] FailedDeletes[] FailedInserts[] Is it more efficient to do it this way, or do it in the case of an associative array controlling several sub arrays "Failures" array(){ ["Updates"] => array(){ [0] => 12 [1] => 41 } ["Deletes"] => array(){ [0] => 122 [1] => 414 [1] => 43 } ["Inserts"] => array(){ [0] => 12 } }

• Explicit call of Runnable.run

  - by klaudio

  Hi, I have a question. Somebody, who was working on my code before me, created some method and passed Runnable as parameter, more likely: void myMethod(Runnable runnable){ runnable.run(); } Then calling myMethod out of main looks like: public static void main(String args[]) { try { myMethod(new Runnable(){ public void run() { //do something...; }}); } catch (Throwable t) { } } So, to supply parameter to myMethod I need to instantiate object of (in this case anonymous) class implementing Runnable. My question is: is it necessary to use Runnable in this example? Can I use any different interface? I mean I can create new interface with single method i.e. interface MyInterface{ void doThis(); } then change look of myMethod: void myMethod(MyInterface myObject){ myObject.doThis(); } And of course client too: public static void main(String args[]) { try { myMethod(new MyInterface (){ public void doThis() { //do something...; }}); } catch (Throwable t) { } } Or maybe something is about Runnable?!

• MS Word to Stylesheet

  - by Chris Johnson

  Is there an easy way to automatically convert a bunch of MS Word documents to xslt stylesheets that can be displayed in the browser? What I have is a large collection of forms in Word format that have to be displayed in the browser, or sent to the user, with known fields populated from a data source, edited by a user and, finally, printed (including the original headers and footers). The data entered by the user will not need to be saved. I'm not sure if converting the documents to stylesheets is even feasible. Maybe someone has a better idea of how to achieve this? Installing Office on the server is not an option in my case.

• build a chrome extension in order to upload images (from clipboard)

  - by dayscott

  I wanted to write a simple chrome extension in order to substitute the following sequence of steps which i have to do very often for university: make screenshot of something edit screenshot in Paint save unnamend.png to harddrive upload unnamed.png to imageshack.us/pic-upload.de or any other website share link of image with others. I don't care which image upload service to use, i just want automize this use-case in order to save time (I already red and did a getting-started chrome extension and checked out their API, but that's it, this page: http://farter.users.sourceforge.net/blog/2010/11/20/accessing-operating-system-clipboard-in-chromium-chrome-extensions/ seemed useful, but i couldn't make it overwrite my systems clipboard - moreover i can't find a tutorial which helps me further).

• Writing WCF messages to a text log in configurable directory.

  - by Arsh

  Hello everyone, I have a WCF web service that is deployed at IIS. Part of the web service is to validate the inputs using EntLib 4.1 For ex, the string values can be of specific length and so on. In case of the validation being failed a fault exception is raised and the service is supposed to write the message in log file. How do I go about creating the log file to a location that can be configured from a config file. Basically how do we write messages from IIS (since the service is hosted at IIS, I am assuming that that will be the source !!!!) Regards.

• Implementation of a C pre-processor in Python or JavaScript?

  - by grrussel

  Is there a known implementation of the C pre-processor tool implemented either in Python or JavaScript? I am looking for a way to robustly pre-process C (and C like) source code and want to be able to process, for example, conditional compilation and macros without invoking an external CPP tool or native code library. Another potential use case is pre-processing within a web application, within the web browser. So far, I have found implementations in Java, Perl, and of course, C and C again. It may be plausible to use one of the C to JavaScript compilers now becoming available. The PLY (Python Lex and Yacc) tools include a cpp implemented in Python.

• How to get the list of files in a directory in a shell script?

  - by jrharshath

  Hi, I'm trying to get the contents of a directory using shell script. My script is: for entry in `ls $search_dir`; do echo $entry done where $search_dir is a relative path. However, $search_dir contains many files with whitespaces in their names. In that case, this script does not run as expected. I know I could use for entry in *, but that would only work for my current directory. I know I can change to that directory, use for entry in * then change back, but my particular situation prevents me from doing that. I have two relative paths $search_dir and $work_dir, and I have to work on both simultaneously, reading them creating/deleting files in them etc. So what do I do now? PS: I use bash.

• CoreData: Sort and Section on Relationships

  - by David.Chu.ca

  I have two questions about using Core Data. Taking the typical case of Employee and Department as an example. The Employee entity has a relationship field "deparment" as to-one to Department, and the Department entity has a relationship "employee" as to-many to Employee entity. I would like to display all the employees in a TableView in sections of department's names. I think that the NSFetchedResultsController should use Employee as entity. I am not sure how to use Department's name as a sort criteria, since it is in an employee's relationship field department's name. Can you use "DepartmentName" as a sort and add this to Employee entity class as a method which will return department's name for a given employee? The second question is the section name. I would like to use department names as sections. Can I use the above method as sectionKeyPath's value for the NSFethedResultsController? Not sure if I am on the right track.

• FlexBuilder 3 Linked folders not picking up as files.

  - by Jafin

  I am using Flex Builder 3 to write a flex component. I have created a real folder path \common. Under common I create a Linked Folder to Session. Session points to a shared source folder with a item with a namespace of common\Session\ClassName. When I go to compile the project FlexBuilder warns that it was unable to find the type. if I stop using Linked folders and create a physical \common\Session\ in my project and place SessionInfo.as in the folder then it works. just in case my textual explanation is a bit obscure here is the layout. \src\common\Session\SessionInfo.as namespace of SessionInfo is common.Session. If you need any further info just let me know.

• How to edit default.aspx on SharePoint site without SharePoint Designer

  - by Magnus Johansson

  On several occations, I have faced the situation that the default.aspx page on a Site doesn't work. More specifically, a reference to a WebPart and/or Control is throwing a error because the assembly is not found. Fine, you just fire up the dreaded SharePoint Designer and remove the dependency line. However, if I wanted to use this method when not having SharePoint Designer, how could this be done? EDIT: Removing the web part using the "?contents=1" web part management page didn't help in my case. The <%@Register tag was still there and had to be removed using SharePoint Designer.
