• How to do simultaneous builds in two Git branches?

  - by james creasy

  I've looked at git-new-workdir, but I don't want the history to be shared because the branches have a release-main relationship. That is, changes in the release branch I want to propagate to the main line, but changes in the main line I don't want in the release line. A common pattern for me is to fix a bug in the release line, integrate it to the main line, then start builds in both branches at the same time. Is there a way to do this with git-new-workdir, do I need to clone, or is there a better solution? Thanks

• Disabled Select drop down checking through PHP

  - by user541597

  I have a couple of drop down boxes I access through POST with PHP. When the boxes are disabled and not equal to zero I have the program do something. However when they are disabled I do not want them to do anything. The way I check if the boxes are active is by using an if statement if ($_POST['box'] != "blank"){ //do something } So basically I check if the box is not in the default blank position run the if statement. However when it is disabled I am not sure how to check or what kind of value it returns if any. What can I add to the if statement so it will not go into the loop when the boxes are disabled? I tried: if ($_POST['box'] != "blank" || $_POST['box'] != ""){ //do something } But that did not work. Any ideas?

• ActiveRecord date format

  - by Mongus Pong

  I've run into a spot of bother with date formats in our Rails application. I have a date field in our view which I want to be formatted as dd/mm/yy. This is how the user will expect to enter their dates, and the datepicker control uses this format. However, Active Record seems to be expecting mm/dd/yy. If I enter 01/03/2010, this gets put in as 03 January 2010. If I enter 25/03/2010, this gets put in a null. How do I get ActiveRecord to expect Her Majesties date format?

• Activate first workbook after closing second one?

  - by user1830217

  Open workbook A. Code in A opens workbook B. B is now the active WB. Code in B ends with ThisWorkBook.Close B closes, so A appears. Problem is, I can't get ANY Activate events in WB A to fire automatically after WB B closes. But if I close WB B manually, using mouse to 'x' out the WB, or via the menus, then WB A triggers Activate events. Somehow using VBA to close WB B prevents WB A Activate events from triggering. Same results in Excel 97 and 2003 Am I missing something, or is there a workaround?? Thanks! John

• What do you name your files when using MVC?

  - by sprugman

  When using the MVC pattern, which I'm not terribly experienced with, I find myself naming things like this: /app/views/widget.php /app/models/widget.php /app/controllers/widget.php That appeals to me because it's easy to find associated classes, and I lean towards shorter names when practical. However, when I'm looking in my IDE, I see three different files called widget.php, which is confusing. I'm tempted to add "_v", "_c", "_m" or something to each name. How do you handle this? FWIW, I'm using CodeIgniter at the moment, and I don't know if there are any special benefits to using a particular convention, or any standard practices. Regardless, I'm intersted in the best-practices from various platforms.

• How to run a module

  - by Jimmy

  I have a module file containing the following functions: def replace(filename): match = re.sub(r'[^\s^\w]risk', 'risk', filename) return match def count_words(newstring): from collections import defaultdict word_dict=defaultdict(int) for line in newstring: words=line.lower().split() for word in words: word_dict[word]+=1 for word in word_dict: if'risk'==word: return word, word_dict[word] when I do this in IDLE: >>> mylist = open('C:\\Users\\ahn_133\\Desktop\\Python Project\\test10.txt').read() >>> newstrings=replace(mylist) ### This works fine. >>> newone=count_words(newstrings) ### This leads to the following error. I get the following error: Traceback (most recent call last): File "<pyshell#134>", line 1, in <module> newPH = replace(newPassage) File "C:\Users\ahn_133\Desktop\Python Project\text_modules.py", line 56, in replace match = re.sub(r'[^\s^\w]risk', 'risk', filename) File "C:\Python27\lib\re.py", line 151, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or buffer Is there anyway to run both functions without saving newstrings into a file, opening it using readlines(), and then running count_words function?

• What is the right way to implement communication between java objects?

  - by imoschak

  I'm working on an academic project which simulates a rather large queuing procedure in java. The core of the simulator rests within one package where there exist 8 classes, each one implementing a single concept. Every class in the project follows SRP. These classes encapsulate the behavior of the simulator and inter-connect every other class in the project. The problem that has arisen is that most of these 8 classes are, as is logical i think, tightly coupled and each one has to have working knowledge of every other class in this package in order to be able to call methods from it when needed. The application needs only one instance of each class so it might be better to create static fields for each class in a new class and use that to make calls -instead of preserving a reference in each class for every other class in the package (which I'm certain that is incorrect)-, but is this considered a correct design solution? or is there a design pattern maybe that better suits my needs?

• C++ Function Calling Itself

  - by Ben

  Suppose I wish to have a function that fills an array either in pattern x,y,x,y,x,ywhere x and y are variables defined by some algorithm and x,y,z,x,y,z where x, y and z are variables defined by the same algorithm. This should continue for all number of variables. Is this a viable way to implement it. int recurse_n(int n) { while(n > 0) { --n; recurse_n(n); n = 0; // Use algorithm here } }

• how to use ByteArrayOutputStream and DataOutputStream simultaneously (Java)

  - by Manuel

  Hi! I'm having quite a problem here, and I think it is because I don't understand very much how I should use the API provided by Java. I need to write an int and a byte[] into a byte[] I thought of using a DataOutputStream to solve the data writing with writeInt(int i) and write(byte[] b), and to be able to put that into a byte array, I should use ByteArrayOutputStream's method toByteArray(). I understand that this classes use the Wrapper pattern, so I had two options: DataOutputStream w = new DataOutputStream(new ByteArrayOutputStream()); or ByteArrayOutputStream w = new ByteArrayOutputStream(new DataOutputStream()); but in both cases, I "loose" a method. in the first case, I can't access the toByteArray method, and in the second, I can't access the writeInt method. How should I use this classes together?

• RFC822 Timezone Parsing in Java

  - by Jamen

  Hi, I have a JS date that is being converted by Dojo into RFC822 format. The function call - dojo.date.toRfc3339(jsDate), generates the following date - 2007-02-26T20:15:00+02:00. I have an application that uses a Java date SimpleDateFormat to parse in the dates generated above. I am having problems parsing this date format due to the timezone. I have attempted to use yyyy-mm-DD'T'hh:mm:ssZ This fails as the 'Z' for timezone doesn't expect a ':' character. Does anyone know how I would specify a pattern to handle a RFC822 date with the ':'? Thanks Jamen

• What data (if any) persists across web-requests in Ruby on Rails?

  - by Daniel Beardsley

  I decided to use the singleton design pattern while creating a view helper class. This got me thinking; will the singleton instance survive across requests? This led to another question, Which variables (if any) survive across web requests and does that change depending on deployment? (Fastcgi, Mongrel, Passenger, ...) I know that Controller instance variables aren't persisted. I know Constants are persisted (or reloaded?). But I don't know about class variables, instance variables on a class, Eigenclasses, ...

• Incrementing through mysql PHP

  - by Rawdon

  I am looking at try to increment and decrement by three records through a table and present those records. Say if the id '4' is currently active. I want the to be display the ID's and category of 3.2.1 and 5.6.7 from an increment and decrement So far I have: $stmt = $db->query("SELECT id, category FROM test"); $stmt->execute(); while ($results = $stmt->fetch(PDO::FETCH_ASSOC)) { $current = $results['id']; $category = $results['category']; $next = array(array('slide_no' => $current, 'category' => $category)); } print_r($next); Now with this, I am getting back every row in the table. I'm now getting confused on how I could increment and decrement the records by 3 and make sure that the category will also increment correctly. Thank you very much.

• In Rails models; for symbols get automatically converted to YAML when saving to DB. What is the corr

  - by Ram

  In my model example Game, has a status column. But I usually set status by using symbols. Example self.status = :active MATCH_STATUS = { :betting_on => "Betting is on", :home_team_won => "Home team has won", :visiting_team_won => "Visiting team has one", :game_tie => "Game is tied" }.freeze def viewable_status MATCH_STATUS[self.status] end I use the above Map to switch between viewable status and viceversa. However when the data gets saved to db, ActiveRecord appends "--- " to each status. So when I retrieve back the status is screwed. What should be the correct approach?

• Wordpress Custom Type permalink containing Taxonomy slug

  - by treznik

  I'm trying to create a permalink pattern for a Custom Type, that includes one of its taxonomies. The taxonomy name is known from the start (so I'm not trying to add or mix all of its taxonomies, just a specific one), but the value will by dynamic, of course. Normally, the Custom Type permalink is built using the rewrite arg with the slug param, but I don't see how I could add a dynamic variable in there. http://codex.wordpress.org/Function_Reference/register_post_type I'm guessing a custom solution is required, but I'm not sure what the best unintrusive approach would be. Is there a known practice for this or has anyone built something similar recently? I'm using WP 3.2.1 btw.

• StructureMap DI on Model Assembly

  - by Dan dot net

  I’m new to Dependency Injection and had a question/need guidance. I had an application that used the repository pattern for data access. I used StructureMap to get the correct repository and all worked well. I have since broken out my model (including the repository logic) into its own assembly and added a service layer. In the interest of DI the service layer class takes an IRepository in its constructor. This seems wrong to me as now all consumers of my model need to know about the repository (at least configure their DI to know which one to use). I feel like that is getting into the guts of the model. What sounds wrong with this?

• How to test if Scala combinator parser matches a string

  - by W.P. McNeill

  I have a Scala combinator parser that handles comma-delimited lists of decimal numbers. object NumberListParser extends RegexParsers { def number: Parser[Double] = """\d+(\.\d*)?""".r ^^ (_.toDouble) def numbers: Parser[List[Double]] = rep1sep(number, ",") def itMatches(s: String): Boolean = parseAll(numbers, s) match { case _: Success[_] => true case _ => false } } The itMatches function returns true when given a string that matches the pattern. For example: NumberListParser.itMatches("12.4,3.141") // returns true NumberListParser.itMatches("bogus") // returns false Is there a more terse way to do this? I couldn't find one in the documentation, but my function sees a bit verbose, so I wonder if I'm overlooking something.

• how to get the second batch and 3rd batch in the same query result in oracle sql + yii framework?

  let' say i have 20 results in the sql query. if am gonna use the limit in the yii active record, I'll obviously get the first four from the result, but what if i wanna get the 2nd four and then 3rd four in the same query result ? how to query that via sql ? e.g $criteria2 = new CDbCriteria(); $criteria2->select = 'USERID, ADID ,ADTYPE, ADTITLE, ADDESC, PAGEVIEW, DISPPUBLISHDATE'; $criteria2->addCondition("STATUS = 1"); $criteria2->order = '"t".PAGEVIEW DESC,"t".PUBLISHDATE DESC'; $criteria2->limit = 4; $criteria2->with = array('subcat','adimages'); $result = $this->findAll($criteria2); return $result;

• Queues And Wait Handles in C#

  - by Michael Covelli

  I've had the following code in my application for some years and have never seen an issue from it. while ((PendingOrders.Count > 0) || (WaitHandle.WaitAny(CommandEventArr) != 1)) { lock (PendingOrders) { if (PendingOrders.Count > 0) { fbo = PendingOrders.Dequeue(); } else { fbo = null; } } // Do Some Work if fbo is != null } Where CommandEventArr is made up of the NewOrderEvent (an auto reset event) and the ExitEvent (a manual reset event). But I just realized today that its not thread safe at all. If this thread gets interrupted right after the first (PendingOrder.Count 0) check has returned false. And then the other thread both enqueues an order and sets the NewOrderEvent before I get a chance to wait on it, the body of the while loop will never run. What's the usual pattern used with a Queue and an AutoResetEvent to fix this and do what I'm trying to do with the code above?

• Java Scanner - next String until a | is found

  - by user1375883

  Currently I'm trying to read through some basic cells, in this format: +-------+-------+ | | | +-------+-------+ Now I need to get the string representation of the cell's contents and send it off to another method. The problem is that the cells have no pre-defined length. I'm reading these from a file, so my easiest option should be to just use the Scanner I already have set up. Problem is, I don't really know how for this case. I have a strong feeling that I need to use the pattern somehow, but I'm at a complete loss on how to do it. I could also probably just build it up somehow, but that strikes me as being painfully slow.

• How to split row into multiple rows from the MySQL?

  - by user2818537

  I have a MySQL data table, in which I have more than 2 columns. First column has a unique value clinical trial value whereas second column has disease information. There are, in most of the cases, more than 2 disease names in one cell for a single id. I want to spilt those rows which cell contains two or more than two diseases. There is a pattern for searching also, i.e. small character is immediately followed by capital character., e.g. MalariaDengueTuberculosis like this. Suppose for these three diseases there is unique id, it should show like the following: NCT-ID disease 4534343654 Maleria 4534343654 Dengue 4534343654 Tubercoulsosis

  I am creating a pricing program. I need to calculate the amounts according to the current tax list in the US (in various places). I want to have a button 'Update taxes' in the administrative settings of the application, so when the user clicks it, it should download from somewhere the active tax amounts. So I actually want to have a function decimal GetTax(string zip). Does anyone knows about a free downloadable xml, or RSS accessible or even a website that I can crawle in and get this info from?

• Regex: Match opening/closing chars with spaces

  - by Israfel

  I'm trying to complete a regular expression that will pull out matches based on their opening and closing characters, the closest I've gotten is ^(\[\[)[a-zA-Z.-_]+(\]\]) Which will match a string such as "[[word1]]" and bring me back all the matches if there is more than one, The problem is I want it to pick up matchs where there may be a space in so for example "[[word1 word2]]", now this will work if I add a space into my pattern above however this pops up a problem that it will only get one match for my entire string so for example if I have a string "Hi [[Title]] [[Name]] [[surname]], How are you" then the match will be "[[Title]] [[Name]] [[surname]]" rather than 3 matches "[[Title]]", "[[Name]]", "[[surname]]". I'm sure I'm just a char or two away in the Regex but I'm stuck, How can I make it return the 3 matches. Thanks

• bash screen title usage (screen -t "something")

  - by atrioom

  I was working with screen lately and wanted to use the -t option for it. What's the point of the-t option if the title of the screen does not show anywhere like when using -list or within the screen when it's attached? There is a command CTRL-A double-quote(") to see all active screens, and then it shows the title, but that does not really do the job, because I have to have the screen attached already. I want to read out the title BEFORE attaching any screens, to attach the right one in the first place. Is there a method to use -t in a convenient way? Edit: There is one method: "ctrl-a "" and then "ctrl-a {numberofscreen}". I guess that's the best way to use the screen titles?

• Install a certficate on a device

  I need to install a certificate on a Windows Mobile device. I have tried creating a cab file to do it, but the cab file fails to run. I have a lot of devices that are not all physically near me that I am going to need to put this on, so any manual process is just not feasible (ie, if it needs active sync then it is not going to work). Any ideas on how to do this? Visual Studio does not seem to support what I am trying to do.
