  • Python: Count lines and differentiate between them

    - by Mister X
    I'm using an application that gives a timed output based on how many times something is done in a minute, and I wish to manually take the output (copy paste) and have my program, and I wish to count how many times each minute it is done. An example output is this: 13:48 An event happened. 13:48 Another event happened. 13:49 A new event happened. 13:49 A random event happened. 13:49 An event happened. So, the program would need to understand that 2 things happened at 13:48, and 3 at 13:49. I'm not sure how the information would be stored, but I need to average them after, to determine an average of how often it happens. Sorry for being so complicated!

  • How to add jsf components in javascript?

    - by Guru
    Is it possible to add JSF Components using javascript? In my case , on change of a select option , i need to display a different combination of input controls (like text box(s)). I thought i could use a element and innerHTML property to display the dynamic controls.But it seems to not work!!! <h:selectOneMenu id="browseType" class="TextBlackNormal" value="#{adminBean.browseType}" onchange="showDynamicBox(this);" valueChangeListener="#{adminBean.theValueChanged}"> <f:selectItems value="#{adminBean.browseTypeList}" /> </h:selectOneMenu> &#160;&#160;&#160;</td> <td> <div id="dynamicBox" style="display:block"><h:inputText class="TextBlackNormal" size="32" name="browseValue" id="browseValue" value="#{adminBean.browseValue}" /></div> </td> javascript code : ~~~~~~~~~~~~~~~~ function showDynamicBox(selectObjj) { //alert('showDynamicBox ' +showDynamicBox); if(selectObjj.options[selectObjj.selectedIndex].value=='IBD/Office/IP' || selectObjj.options[selectObjj.selectedIndex].value=='APA#' ) { alert('just about to change'); document.getElementById("dynamicBox").innerHTML='<h:inputText class="TextBlackNormal" size="3" name="val1" id="val1" /> <h:inputText class="TextBlackNormal" size="3" name="val2" id="val2" /> <h:inputText class="TextBlackNormal" size="3" name="val3" id="val3" /> '; alert(' --> ' +document.getElementById("dynamicBox").innerHTML); }else{ alert('back to pavillion'); document.getElementById("dynamicBox").innerHTML='<h:inputText class="TextBlackNormal" size="32" name="browseValue" id="browseValue" value="#{adminBean.browseValue}" />'; } }

  • Query two tables from different schema

    - by Guru
    Hi- I have two different schemas in Oracle (say S1, S2). And two tables in those schemas(say S1.Table1, S2.Table2). I want to query these two tables from schema S1. Both S1 and S2 are in different databases. From DB1 - Schema S1, I want to do something like this, select T1.Id from S1.Table1 T1 , S2.Table2 T2 Where T1.Id = T2.refId I know one way of doing this would be creating a DB Link for the second schema and use it in querying. But sadly, I don't have priv to create DB link. Is there some way to do without DB link, like, in TOAD, you can compare two schema objects. But again, two schema objects and it is general comparision. Not like querying them. Any ideas, suggestions are greatly appriciated. Thanks in advance.

  • List of divisors of an integer n (Haskell)

    - by Code-Guru
    I currently have the following function to get the divisors of an integer: -- All divisors of a number divisors :: Integer -> [Integer] divisors 1 = [1] divisors n = firstHalf ++ secondHalf where firstHalf = filter (divides n) (candidates n) secondHalf = filter (\d -> n `div` d /= d) (map (n `div`) (reverse firstHalf)) candidates n = takeWhile (\d -> d * d <= n) [1..n] I ended up adding the filter to secondHalf because a divisor was repeating when n is a square of a prime number. This seems like a very inefficient way to solve this problem. So I have two questions: How do I measure if this really is a bottle neck in my algorithm? And if it is, how do I go about finding a better way to avoid repetitions when n is a square of a prime?

  • Calling Object Methods in Code

    - by Mister R2
    I'm a bit new to PHP, and I'm more experienced with strongly-typed languages such as JAVA, C# or C++.I'm currently writing a web tool in PHP, and I am having an issue trying to do what I want. The simple idea of what I want to do in code is run through some emails I used PHP-IMAP to get. I then create email objects (a class I defined), and put them in an array. Later on the code, however, I cycle through those emails to display them. However, as you might have guessed I'd have an issue with, I try to use an Email Class object method in that later loop -- and I'm pretty sure PHP doesn't know that the variables in the array happen to be Email Class objects! I wrote a toString method, and I want to call it in the loop. While I don't need to do this for the final version of this tool, I would like to find out what I'm missing. This is the class and the loop where I'm calling the method: include 'imap_email_interface.php'; class ImapEmail implements imap_email_interface { // Email data var $msgno; var $to; var $from; var $subject; var $body; var $attachment; // Email behavior /* PHP 4 ~ legacy constructor */ public function ImapEmail($message_number) { $this->__construct(); $this->msgno = $message_number; } /* PHP 5 Constructor */ public function __construct($message_number) { $this->msgno = $message_number; } public function send($send_to) { // Not Yet Needed! Seriously! } public function setHeaderDirectly($TO, $FROM, $SUBJECT) { $this->to = $TO; $this->from = $FROM; $this->subject = $SUBJECT; } public function setHeaderIndirectly($HEADER) { if (isset($HEADER->to[0]->personal)) $this->to = '"'.$HEADER->to[0]->personal.'", '.$HEADER->to[0]->mailbox.'@'.$HEADER->to[0]->host; else $this->to = $HEADER->to[0]->mailbox.'@'.$HEADER->to[0]->host; $this->from = '"'.$HEADER->from[0]->personal.'", '.$HEADER->from[0]->mailbox.'@'.$HEADER->from[0]->host; $this->subject = $HEADER->subject; } public function setBody($BODY) { $this->body = $BODY; } public function setAttachment($ATTCH) { $this->attachment = $ATTCH; } public function toString() { $str = '[TO]: ' . $this->to . '<br />' . '[FROM]: ' . $this->from . '<br />' . '[SUBJECT]: ' . $this->subject . '<br />'; $str .= '[Attachment]: '.$this->attachment.'<br />'; return $str; } } ?> The Loop: foreach ($orderFileEmails as $x) { $x->toString(); echo '<br /><br />'; } Any ideas?

  • FlockDB - What is it? And best cases for it uses.

    - by Guru
    Just came across FlockDB graph database. Details at github /flockDB. Twitter claims it uses FlockDB for the following: Twitter runs FlockDB on a large cluster of machines. we use it to store social graphs (who follows whom, who blocks whom) and secondary indices at twitter. At first glance, setup and trying it doesn't look straight forward. Have anyone already used it / setup this? If so, please answer the following general queries. What kind of applications is it better suited for? (Twitter claims it is simple and very rough, it remains to see what it meant though) How is FlockDB better than other graph db / noSQL db. Have you setup FlockDB, used it for a application? Early advices any? Note: I am evaluating the FlockDB and other graph databases mainly for learning them. Perhaps, I will build an application for that.

  • Matching Line Boundaries in a Regular Expression (Pattern.MULTILINE/(?m)) is broken in Java?

    - by Mister M. Bean
    The example on http://www.exampledepot.com/egs/java.util.regex/Line.html gives false for me twice but should'nt! Why? CharSequence inputStr = "abc\ndef"; String patternStr = "abc$"; // Compile with multiline enabled Pattern pattern = Pattern.compile(patternStr, Pattern.MULTILINE); Matcher matcher = pattern.matcher(inputStr); boolean matchFound = matcher.find(); // true // Use an inline modifier to enable multiline mode matchFound = pattern.matches(".*abc$.*", "abc\r\ndef"); // false System.out.println(matchFound); // false matchFound = pattern.matches("(?m).*abc$.*", "abc\r\ndef"); // true System.out.println(matchFound);// false !!!!!

  • Whats the difference between \z and \Z in a regular expression and when and how do I use it?

    - by Mister M. Bean
    From http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Pattern.html: \Z The end of the input but for the final terminator, if any \z The end of the input But what does it mean in practice? Can you give me an example when I use either the \Z or \z. In my test I thought that "StackOverflow\n".matches("StackOverflow\\z") will return true and "StackOverflow\n".matches("StackOverflow\\Z") returns false. But actually both return false. Where is the mistake?

  • My Tech Ed North America Preview - Content Edition

    - by Chris Gardner
    As I promised in my last post, I feel the need to give you a rundown on all the technical content I am looking forward to checking out at Tech Ed this year. We shall start with the content I know I'll be able to see. This would be some demo stations in the Technical Learning Center. I will DEFINITELY be checking out the Windows Phone Device Bar. I will admit that I am a bit of a phone snob, and I just want to manhandle all that sexy, sexy tech. I am also planning on talking to the Windows Phone team and the Azure team. Year after year, I end up spending more time in either the TLC or taking certification tests than anywhere else. This leads me to the one "Exam Cram" session I hope to attend. There is a session to cram for 70-599: Designing and Developing Windows Phone Applications. I know this seems odd. I'm (sort of) an XNA guru. However, I'm not that up on my Silverlight. I know enough to add Silverlight to an XNA project. Now, let's talk breakout sessions. We always need to keep track of where we're going. I know, I talk about solving problems over forcing buzz words. However, it is important to know what those buzz words before you tell people not to use them. For this, we will look to the "What's New in Visual Studio 11" and "What's New in Microsoft .NET Framework 4.5." Of course, we do talk bad about buzz words around here. For this, I'm really looking forward to "Visual C#/Visual Basic: Becoming a Guru with Existing Features." I still have .NET 2 tricks that are crucial to my internal libraries. In depth knowledge will NEVER trump shortcut libraries. There is a session in ASP.NET for phones and tablets. For those of you that have not tried to use ASP.NET on a mobile device, there is one thing you really need to understand. Mobile devices don't use scroll bars. That's right; the thing with the least screen real estate doesn't use scroll bars. Thus, I am hoping this session will give some good advice in having an ASP.NET site target both mobile and desktop. The last "business only" session "The Accidental Team Foundation Server Admin." T & W Operations is a VERY small business. As such, I am the TFS admin because I'm the developer that is also the SQL Guru. I keep my server up, but it'd be nice to know some really cool tricks for the part time guy. This leads us the the fun sessions. Coding4Fun has a Kinect session. The Twitter followers will remember that I now have a Kinect for Windows sitting on my desk at work. I have gotten pretty handy with the device, but I KNOW I'm missing some good stuff. Finally, we come to Brian Prince's session on "Making Crazy Money with Games and the Cloud." Never mind the fact that we're using Azure at work. Never mind the fact that I'm actually using the cloud in a game. Never mind the fact that the session has the terms "Crazy Money" and "Games" in the title. If you've never seen Brian Prince speak, you're missing out. In the Hands-on-Labs, we are not allowed to make our own schedule. Instead, we're asked what sessions we can't miss, and they try to schedule around those times. This was the one session I said I couldn't miss. This should complete the technical content for the conference. Coming soon, I'll dig into the certifications I hope to attain. Then, we'll talk about the social activities for the week. Here's a preview of that. I am a member of The Krewe...

  • Coping with feelings of technical mediocrity

    - by Karim
    As I've progressed as a programmer, I noticed more nuance and areas I could study in depth. In part, I've come to think of myself from, at one point, a "guru" to now much less, even mediocre or inadequate. Is this normal, or is it a sign of a destructive excessive ambition? Background I started to program when I was still a kid, I had about 10 or 11 years. I really enjoy my work and never get bored from it. It's amazing how somebody could be paid for what he really likes to do and would be doing it anyway even for free. When I first started to program, I was feeling proud of what I was doing, each application I built was for me a success and after 2-3 year I had a feeling that I'm a coding guru. It was a nice feeling. ;-) But the more I was in the field and the more types of software I started to develop, I was starting to have a feeling that I'm completely wrong in thinking I'm a guru. I felt that I'm not even a mediocre developer. Each new field I start to work on is giving me this feeling. Like when I once developed a device driver for a client, I saw how much I need to learn about device drivers. When I developed a video filter for an application, I saw how much do I still need to learn about DirectShow, Color Spaces, and all the theory behind that. The worst thing was when I started to learn algorithms. It was several years ago. I knew then the basic structures and algorithms like the sorting, some types of trees, some hashtables, strings, etc. and when I really wanted to learn a group of structures I learned about 5-6 new types and saw that in fact even this small group has several hundred subtypes of structures. It's depressing how little time people have in their lives to learn all this stuff. I'm now a software developer with about 10 years of experience and I still feel that I'm not a proficient developer when I think about things that others do in the industry.

  • What technology should I use for a complex report?

    - by SeaDrive
    I have a task to generate reports from a Visual Studio C# application. This is a replacement (caused by new requirements) for a program written using the built-in implementation of Crystal Reports. Although workable, it was far from ideal. The reports have conditional content (If type=1, print this, if type=2 print that.) Crystal does not adjust spacing dynamically and the various pieces were not the same length making for some unprofessional-looking spacing. I had thought of generating the reports in HTML, which would be feasible, but I'm concerned that you lose a degree of control, and I may be asked, e.g. to "move this up a bit" or similar which may be tricky. I'm not either a Crystal guru or an HTML guru. What other reporting technologies are available that would make it easy to drop in parts of different sizes, do table layouts, etc.?
