• Classifying captured data in unknown format?

  - by monch1962

  I've got a large set of captured data (potentially hundreds of thousands of records), and I need to be able to break it down so I can both classify it and also produce "typical" data myself. Let me explain further... If I have the following strings of data: 132T339G1P112S 164T897F5A498S 144T989B9B223T 155T928X9Z554T ... you might start to infer the following: possibly all strings are 14 characters long the 4th, 8th, 10th and 14th characters may always be alphas, while the rest are numeric the first character may always be a '1' the 4th character may always be the letter 'T' the 14th character may be limited to only being 'S' or 'T' and so on... As you get more and more samples of real data, some of these "rules" might disappear; if you see a 15 character long string, then you have evidence that the 1st "rule" is incorrect. However, given a sufficiently large sample of strings that are exactly 14 characters long, you can start to assume that "all strings are 14 characters long" and assign a numeric figure to your degree of confidence (with an appropriate set of assumptions around the fact that you're seeing a suitably random set of all possible captured data). As you can probably tell, a human can do a lot of this classification by eye, but I'm not aware of libraries or algorithms that would allow a computer to do it. Given a set of captured data (significantly more complex than the above...), are there libraries that I can apply in my code to do this sort of classification for me, that will identify "rules" with a given degree of confidence? As a next step, I need to be able to take those rules, and use them to create my own data that conforms to these rules. I assume this is a significantly easier step than the classification, but I've never had to perform a task like this before so I'm really not sure how complex it is. At a guess, Python or Java (or possibly Perl or R) are possibly the "common" languages most likely to have these sorts of libraries, and maybe some of the bioinformatic libraries do this sort of thing. I really don't care which language I have to use; I need to solve the problem in whatever way I can. Any sort of pointer to information would be very useful. As you can probably tell, I'm struggling to describe this problem clearly, and there may be a set of appropriate keywords I can plug into Google that will point me towards the solution. Thanks in advance

• I need help with creating a data structure in PHP

  - by alex

  What I need to do is have a data structure that shows jobs organised into 14 day periods, but only when an id is the same. I've implemented all sorts of stuff, but they have failed miserably. Ideally, maybe a SQL expert could handle all of this in the query. Here is some of my code. You can assume all library stuff works as expected. $query = 'SELECT date, rig_id, comments FROM dor ORDER BY date DESC'; $dors = Db::query(Database::SELECT, $query)->execute()->as_array(); This will return all jobs, but I need to have them organised by 14 day period with the same rig_id value. $hitches = array(); foreach($dors as $dor) { $rigId = $dor['rig_id']; $date = strtotime($dor['date']); if (empty($hitches)) { $hitches[] = array( 'rigId' => $rigId, 'startDate' => $date, 'dors' => array($dor) ); } else { $found = false; foreach($hitches as $key => $hitch) { $hitchStartDate = $hitch['startDate']; $dateDifference = abs($hitchStartDate - $date); $isSameHitchTimeFrame = $dateDifference < (Date::DAY * 14); if ($rigId == $hitch['rigId'] AND $isSameHitchTimeFrame) { $found = true; $hitches[$key]['dors'][] = $dor; } } if ($found === false) { $hitches[] = array( 'rigId' => $rigId, 'startDate' => $date, 'dors' => array($dor) ); } } } This seems to work OK splitting up by rig_id, but not by date. I also think I'm doing it wrong because I need to check the earliest date. Is it possible at all to do any of this in the database query? To recap, here is my problem I have a list of jobs with all have a rig_id (many jobs can have the same) and a date. I need the data to be organised into hitches. That is, the rig_id must be the same per hitch, and they must span a 14 day period, in which the next 14 days with the same rig_id will be a new hitch. Can someone please point me on the right track? Cheers

• Normalization of database for timesheet tool and ensure data integrity

  - by fireeyedboy

  I'm creating a timesheet application. I have the following entities (amongst others): Company Employee = an employee associated with a company Client = a client associated with a company So far I have the following (abbreviated) database setup: Company - id - name Employee - id - companyId (FK to Company.id) - name Client - id - companyId (FK to Company.id) - name Now, I want an employee to be associated with a client, but only if that client is associated with the company the employee works for. How would you guarantee this data integrity on a database level? Or should I just depend on the application to guarantee this data integrity? I thought about creating a many to many table like this: EmployeeClient - employeeId (FK to Employee.id) - companyId \ (combined FK to Client.companyId, Client.id) - clientId / Thus, when I insert a client for an employee along with the employee's company id, the database should prevent this when the client is not associated with the employee's company id. Does this make sense? Because this still doesn't guarantee the employee is associated with the company. How do you deal with these things? UPDATE The scenario is as followed: A company has multiple employees. Employees will only be linked to one company. A company has multiple clients also. Clients will only be linked to one company. (Company is a sandbox, so to speak). An employee of a company can be linked to a client of it's company, but only if the client is part of the company's clientele. In other words: The application will allow a company to create/add employees and create/add clients (hence the companyId FK in the Employee and Client tables). Next, the company will be allowed to assign certain clients to certain of it's employees (EmployeeClient table). Imagine an employee working on projects for a few clients for which s/he can write billable hours, but the employee must not be allowed to write billable hours for clients they are not assigned to by their employer (the company). So, employees will not automatically have access to all their company's clients, but only to those that the company has selected for them. Hopefully this has shed some more light on the matter.

• jqModal and jquery widget long shot

  - by rod

  Hi All, I just started playing around with jquery widgets within my jqmodals in my mvc app. I know this may be a long shot but I'll take it. Initially, I can click the Add link, get the alert ("which is the prize", watching too much tv), next click cancel to close modal and get the desired results. I can, then, click the Edit link and get the same desired results. However, if I click Edit link first then I try to click the Add link, "forget about it" I don't get the alert (which means my widget did not init). But I can still go back and click Edit and get the prize (the alert message). ajax: "/Home/EditPrintAdLine" and ajax: "/Home/AddPrintAdLine" render the same web user control Any ideas? <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>. </p> <div id="printAdLineEditDialog" class="jqmWindow"></div> <div id="printAdDialog" class="jqmWindow"></div> <table> <tr><td><a id="printAdLineItem" href="#">Add a Line Item</a></td></tr> <tr><td><a id="editPrintAdLine" href="#">Edit</a></td></tr> </table> <script type="text/javascript"> $(document).ready(function() { $.widget("ui.my_widget", { _init: function() { alert("My widget was instantiated"); } }); // Add line $('#printAdLineItem').click(function(e) { $('#printAdDialog').jqmShow(this); e.preventDefault(); }); $('#printAdDialog').jqm({ ajax: "/Home/AddPrintAdLine", onLoad: function(hash) { $('#PrintAdLine_RunDate').my_widget(); } }); // Edit line $('#editPrintAdLine').click(function(e) { $('#printAdLineEditDialog').jqmShow(this); e.preventDefault(); }); $('#printAdLineEditDialog').jqm({ ajax: "/Home/EditPrintAdLine", onLoad: function(hash) { $('#PrintAdLine_RunDate').my_widget(); } }); }); </script> </asp:Content>

• How to convert a 32bpp image to an indexed format?

  - by Ed Swangren

  So here are the details (I am using C# BTW): I receive a 32bpp image (JPEG compressed) from a server. At some point, I would like to use the Palette property of a bitmap to color over-saturated pixels (brightness 240) red. To do so, I need to get the image into an indexed format. I have tried converting the image to a GIF, but I get quality loss. I have tried creating a new bitmap in an index format by these methods: // causes a "Parameter not valid" error Bitmap indexed = new Bitmap(orig.Width, orig.Height, PixelFormat.Indexed) // no error, but the resulting image is black due to information loss I assume Bitmap indexed = new Bitmap(orig.Width, orig.Height, PixelFormat.Format8bppIndexed) I am at a loss now. The data in this image is changed constantly by the user, so I don't want to manually set pixels that have a brightness 240 if I can avoid it. If I can set the palette once when the image is created, my work is done. If I am going about this the wrong way to begin with please let me know. EDIT: Thanks guys, here is some more detail on what I am attempting to accomplish. We are scanning a tissue slide at high resolution (pathology application). I write the interface to the actual scanner. We use a line-scan camera. To test the line rate of the camera, the user scans a very small portion and looks at the image. The image is displayed next to a track bar. When the user moves the track bar (adjusting line rate), I change the overall intensity of the image in an attempt to model what it would look like at the new line rate. I do this using an ImageAttributes and ColorMatrix object currently. When the user adjusts the track bar, I adjust the matrix. This does not give me per pixel information, but the performance is very nice. I could use LockBits and some unsafe code here, but I would rather not rewrite it if possible. When the new image is created, I would like for all pixels with a brightness value of 240 to be colored red. I was thinking that defining a palette for the bitmap up front would be a clean way of doing this.

• Delaying emails in PHP to avoid exceeding server limit

  - by Andrew P.

  Okay, so here's my problem: I have a list of members on a website, and periodically one of the admins my site (who are not very web or tech savvy) will send a newsletter to the memberlist. My current memberlist is well over 800 individuals long. So, I wrote an email script that sends the email to the full memberlist, with the members listed in the Bcc header. However, I've discovered that my host server has a limit of 300 emails per hour, which I apparently exceed even though the members are listed in the Bcc field. (I wasn't previously aware that the behaviour of Bcc was to send separate emails for each name on the list...) After some thought, I've come to the conclusion that my only solution is to have my script send only the email to only the first 300 emails, wait an hour, and send a second email to the next three hundred, wait another hour, and so on until I've sent the email to the whole member list. Looking around on the internet, I've seen some other solutions people have come up with for delaying emails in PHP. Sleep() is obviously not an option, because I can't just leave the script open and running for 3 or four hours. I've seen some people suggest cron jobs, but I'm not sure how feasible it would be to create three new cron jobs every time I send an email, use them once, and then delete them afterward. The final (and what I think is the smartest) solution I've seen, is to have a table in my database to temporarily store the emails to be delayed and sent later, and then create a cron job that checks this sql table every hour or so, compares the timestamp of the row to the current timestamp, and then sends the email if an hour has passed. So I'm asking you all which method you would recommend. Is there an easier solution that I've completely looked over (aside from getting a different hosting plan. ha!), or is there a cleaner way to do it than the database / cron job approach? tl;dr: I have 800 emails to send in an hour on a server that limits me to 300/hr. Using PHP, find a way to get around this problem in a way that the person sending the email needs only to click "send."

• Issue with parsed text with HTMLCleaner - spaces at the begining of text

  - by ansol90

  Im able to get text using HTMLCleaner from website. The problem is that when I set the text to a TextView it shows the beginning of the text with a big space on it. Here is the screenshot of what im talking about. I have tried android:gravity but nothing happened. Please help. Here is my Code: private class SiteParser extends AsyncTask<String, Void, String> { protected String doInBackground(String... arg) { String output = null; try { HtmlHelper hh = new HtmlHelper(new URL(arg[0])); List<TagNode> news = hh.getnewsByClass("TextoPrint"); for (Iterator<TagNode> iterator = newss.iterator(); iterator .hasNext();) { TagNode divElement = (TagNode) iterator.next(); output = divElement.getText().toString(); } } catch (Exception e) { e.printStackTrace(); } return output; } protected void onPostExecute(String output) { Bundle bundle=new Bundle(); bundle.putString("body",output); Intent mainIntent = new Intent(act, MyView.class); mainIntent.putExtras(bundle); startActivity(mainIntent); act.finish(); } } public class HtmlHelper { TagNode rootNode; public HtmlHelper(URL htmlPage) throws IOException, XPatherException { HtmlCleaner cleaner = new HtmlCleaner(); rootNode = cleaner.clean(htmlPage); } List<TagNode> getnewsByClass(String Classname){ List<TagNode> newsList = new ArrayList<TagNode>(); TagNode divElements[] = rootNode.getElementsByName("div", true); for (int i = 0; divElements != null && i < divElements.length; i++) { String classType = divElements[i].getAttributeByName("id"); if (classType != null && classType.equals(Classname)) { newsList.add(divElements[i]); } } return newsList; } }

• How can I append a description to a Zend_Form_Element?

  - by Mallika Iyer

  I have the following Zend_Form_Element: $imginstructions = "Some description"; $img = $this->createElement('select','img'); $img->setAttrib('class', 'image-select'); $imgdecorator = $img->getDecorator('Description'); $imgdecorator->setOption('escape', false); $img->setLabel('Image:') ->setRequired(true) ->addMultiOptions($images) ->setValue('') ->setDescription($imginstructions) ->addErrorMessage('You must select an image'); $img->size = 5; $this->addElement($img); The description should appear next to the select box. The problem is : When an error is thrown, the html rendered changes so the description shows up below the select box, instead of beside it. HTML rendered before error is thrown: <dd id="img-element"> <select size="5" class="image-select" id="img" name="img" style="display: none;"> ...........options.............. </select> <p class="description">Some Description</p></dd> HTML rendered after error is thrown: <dd id="img-element"> <select size="5" class="image-select" id="img" name="img" style="display: none;"> ...........options.............. </select> <ul class="errors"><li>You must select an image</li></ul> <p class="description">Some Description</p></dd> Is there a way to force the error message to be appended as the last element in the DOM tree for the dd element? Something like: <dd id="img-element"> <select size="5" class="image-select" id="img" name="img" style="display: none;"> ...........options.............. </select> <p class="description">Some Description</p> <ul class="errors"><li>You must select an image</li></ul></dd> so the 'ul' is at the end of the dd DOM tree. Thanks, I appreciate your taking the time to respond to this question!

• [NSIS] Custom radio-buttom INI page via Eclipse

  - by Omegazero

  I'm using Eclipse's create InstallOptions menu to create a custom INI page with radio-buttons for repackaging the Blackberry Desktop installer. There are 2 sections for each type: "Internet" and "Enterprise". I need a user to select 1 of the 2 options and depending on their selection, the page will carry over the selection chosen in the custom page, jump to the INSTFILES page, and continue onto the end. I couldn't find any concrete documentation on getting INI pages to load in the script (I'm probably searching incorrectly), and then pass data from one page to the next (according to fields I guess?) Any help is appreciated.

• JQuery uploadify plugin not working

  Hello, I first used primefaces FileUpload component and it didn't work. Always gave "HTTP Error".

• wget not behaving via IPC::Open3 vs bash

  - by Ryley

  I'm trying to stream a file from a remote website to a local command and am running into some problems when trying to detect errors. The code looks something like this: use IPC::Open3; my @cmd = ('wget','-O','-','http://10.10.1.72/index.php');#any website will do here my ($wget_pid,$wget_in,$wget_out,$wget_err); if (!($wget_pid = open3($wget_in,$wget_out,$wget_err,@cmd))){ print STDERR "failed to run open3\n"; exit(1) } close($wget_in); my @wget_outs = <$wget_out>; my @wget_errs = <$wget_err>; print STDERR "wget stderr: ".join('',@wget_errs); #page and errors outputted on the next line, seems wrong print STDERR "wget stdout: ".join('',@wget_outs); #clean up after this, not shown is running the filtering command, closing and waitpid'ing When I run that wget command directly from the command-line and redirect stderr to a file, something sane happens - the stdout will be the downloaded page, the stderr will contain the info about opening the given page. wget -O - http://10.10.1.72/index.php 2> stderr_test_file When I run wget via open3, I'm getting both the page and the info mixed together in stdout. What I expect is the loaded page in one stream and STDERR from wget in another. I can see I've simplified the code to the point where it's not clear why I want to use open3, but the general plan is that I wanted to stream stdout to another filtering program as I received it, and then at the end I was going to read the stderr from both wget and the filtering program to determine what, if anything went wrong. Other important things: I was trying to avoid writing the wget'd data to a file, then filtering that file to another file, then reading the output. It's key that I be able to see what went wrong, not just reading $? 8 (i.e. I have to tell the user, hey, that IP address is wrong, or isn't the right kind of website, or whatever). Finally, I'm choosing system/open3/exec over other perl-isms (i.e. backticks) because some of the input is provided by untrustworthy users.

• How to get the result for return statement from JSON parsing?

• jQuery selectors - parental problems

  - by aressidi

  Hi there, I have an emote selector that opens up when a user clicks an entry in a diary. The way I've worked it is that the emote selector panel lives hidden at the top of the page. When a user clicks on the 'emote control' associated with an entry, I use JavaScript to grab the HTML of the emote selector panel from the top of the page and insert it next to the entry. Using Firebug, here's what the finished product would look like in the page (snippet from element inspect). I'm trying to get the ID for the class 'emote-control-container' which contains the entry id: <td> <div id="1467002" class="emote-select emote-default">&nbsp;</div> <div class="emote-control-container" id="emote-controls-1467002"> <div id="emote-control-selector"> <div id="emote-control-selector-body"> <ul> <li id="emote-1"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> <li id="emote-2"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> <li id="emote-3"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> <li id="emote-4"><img src="/images/default_emote.gif?1276134900" class="emote-image" alt="Default_emote"></li> </ul> </div> <div id="emote-control-selector-footer"> &nbsp; </div> </div> </div> </td> I need the entry ID along with the emote ID to make a post via AJAX when a user selects an emote from the selector panel by clicking on it. I'm able to get the emote ID just fine with this, which I'm using to alert-out the selected emote ID: jQuery('li').live('click', function(e) { e.preventDefault; var emoteId = this.id; alert(emoteId); }); I'm having trouble traversing up DOM to get the element ID from '.emote-control-container. I've tried everything, but I'd expect this to work, but it doesn't: jQuery('li').live('click', function(e) { e.preventDefault; var entryId = jQuery(this.id).parent(".emote-control-container").attr("id"); alert(entryId); }); What am I doing wrong.? I can't target the ID of the .emote-control-container.

• Animation using AniMate with Unity3D doesn't interact with physical objects

  - by Albz

  I'm designing a maze with Unity3D. The maze has a number of bifurcations and the player will stop before each bifurcation and simply choose left or right. Then an automatic animation will move the player through the next bifurcation till the end of the maze (or till a dead end). To animate the player I'm using AniMate and C# in my Unity project. Using AniMate I'm simply creating a point-to-point animation for each bifurcation (e.g. mage below: from the start/red arrow to point 5) My problem is that my animation script (associated to the "First Person Controller") is not working properly since physics is not respected (the player passes through walls). If in the same project I enable the standard character controls in Unity, then I can navigate in the maze with the physical contrains of walls etc... (i.e. I have colliders). This is an example of the code I'm using when I press left to pass from starting point, trough point 1 to point 2: void FixedUpdate () { if (Input.GetKey(KeyCode.LeftArrow)) { //To point 1 Hashtable props = new Hashtable(); props.Add("position", new Vector3(756f,112f,1124f)); props.Add("physics", true); Ani.Mate.To(transform, 2, props); //To point 2 Hashtable props2 = new Hashtable(); props2.Add("position", new Vector3(731f,112f,1124f)); props2.Add("physics", true); Ani.Mate.To(transform, 2, props2); } } What happens practically when I press the left arrow button is that the player moves directly to point 2 using a straight line passing through the wall. I tried to pass to AniMate "Physics = true" but it doesn't seem to help. Any idea on how to solve this issue? Alternatively... any hint on how to have a more optimized code and just use a series of vector3 coordinates (one for each point) to obtain the simple animation I want without having to declare new Hashtable(); etc... every time? I chose AniMate simply because 1. I'm a beginner with Unity 2. I don't need complex animations (e.g. I don't need to use iTween), just fixed animations along straight lines and I need something really simple and quick to implement in a script. However, if someone has an equally simple solution it will be welcome. thank you in advance for your help

• What is causing this SQL 2005 Primary Key Deadlock between two real-time bulk upserts?

  - by skimania

  Here's the scenario: I've got a table called MarketDataCurrent (MDC) that has live updating stock prices. I've got one process called 'LiveFeed' which reads prices streaming from the wire, queues up inserts, and uses a 'bulk upload to temp table then insert/update to MDC table.' (BulkUpsert) I've got another process which then reads this data, computes other data, and then saves the results back into the same table, using a similar BulkUpsert stored proc. Thirdly, there are a multitude of users running a C# Gui polling the MDC table and reading updates from it. Now, during the day when the data is changing rapidly, things run pretty smoothly, but then, after market hours, we've recently started seeing an increasing number of Deadlock exceptions coming out of the database, nowadays we see 10-20 a day. The imporant thing to note here is that these happen when the values are NOT changing. Here's all the relevant info: Table Def: CREATE TABLE [dbo].[MarketDataCurrent]( [MDID] [int] NOT NULL, [LastUpdate] [datetime] NOT NULL, [Value] [float] NOT NULL, [Source] [varchar](20) NULL, CONSTRAINT [PK_MarketDataCurrent] PRIMARY KEY CLUSTERED ( [MDID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] - stackoverflow wont let me post images until my reputation goes up to 10, so i'll add them as soon as you bump me up, hopefully as a result of this question. ![alt text][1] [1]: http://farm5.static.flickr.com/4049/4690759452_6b94ff7b34.jpg I've got a Sql Profiler Trace Running, catching the deadlocks, and here's what all the graphs look like. stackoverflow wont let me post images until my reputation goes up to 10, so i'll add them as soon as you bump me up, hopefully as a result of this question. ![alt text][2] [2]: http://farm5.static.flickr.com/4035/4690125231_78d84c9e15_b.jpg Process 258 is called the following 'BulkUpsert' stored proc, repeatedly, while 73 is calling the next one: ALTER proc [dbo].[MarketDataCurrent_BulkUpload] @updateTime datetime, @source varchar(10) as begin transaction update c with (rowlock) set LastUpdate = getdate(), Value = t.Value, Source = @source from MarketDataCurrent c INNER JOIN #MDTUP t ON c.MDID = t.mdid where c.lastUpdate < @updateTime and c.mdid not in (select mdid from MarketData where LiveFeedTicker is not null and PriceSource like 'LiveFeed.%') and c.value <> t.value insert into MarketDataCurrent with (rowlock) select MDID, getdate(), Value, @source from #MDTUP where mdid not in (select mdid from MarketDataCurrent with (nolock)) and mdid not in (select mdid from MarketData where LiveFeedTicker is not null and PriceSource like 'LiveFeed.%') commit And the other one: ALTER PROCEDURE [dbo].[MarketDataCurrent_LiveFeedUpload] AS begin transaction -- Update existing mdid UPDATE c WITH (ROWLOCK) SET LastUpdate = t.LastUpdate, Value = t.Value, Source = t.Source FROM MarketDataCurrent c INNER JOIN #TEMPTABLE2 t ON c.MDID = t.mdid; -- Insert new MDID INSERT INTO MarketDataCurrent with (ROWLOCK) SELECT * FROM #TEMPTABLE2 WHERE MDID NOT IN (SELECT MDID FROM MarketDataCurrent with (NOLOCK)) -- Clean up the temp table DELETE #TEMPTABLE2 commit To clarify, those Temp Tables are being created by the C# code on the same connection and are populated using the C# SqlBulkCopy class. To me it looks like it's deadlocking on the PK of the table, so I tried removing that PK and switching to a Unique Constraint instead but that increased the number of deadlocks 10-fold. I'm totally lost as to what to do about this situation and am open to just about any suggestion. HELP!!

• set equal height on multiple divs

  - by Greenie

  I need to set equal height on a series of divs inside another div wrapper. The problem is that I dont want the same height on all of them. The page kind of have 3 columns and the floating divs can be 1, 2 or 3 columns wide. The divs float left, so the following example will give me three rows of divs in my wrapper. How can I set equal height on the divs that are in the same row? In my example I want nr 1 and 2 to have equal height and 3, 4 and 5 another equal height? I cant know beforehand how many divs there is or how wide or high they are. Edit: They can be for instance 300, 600 or 900 px wide and the page width is 900px <div id="wrapper"> <div class="one-wide">nr1</div> <div class="two-wide">nr2</div> <div class="one-wide">nr3</div> <div class="one-wide">nr4</div> <div class="one-wide">nr5</div> <div class="three-wide">nr6</div> </div> Im thinking I somehow need to figure out when the added width of the divs is at the full page width and set equal height on those. Then do the same on the next divs. But I cant wrap my head around it. Currently im just using this to set the height on the children of the wrapper: $.fn.equalHeights = function(px) { $(this).each(function(){ var currentTallest = 0; $(this).children().each(function(i){ if ($(this).height() > currentTallest) { currentTallest = $(this).height(); } }); // for ie6, set height since min-height isn't supported if ($.browser.msie && $.browser.version == 6.0) { $(this).children().css({'height': currentTallest}); } $(this).children('div').css({'min-height': currentTallest}); }); return this; };

• Selenium: How to use stored value in a javascript comparison

  - by dstrube

  I've searched around for the answer to this and found lots of much more complicated questions, but none that gave me insight enough to figure this one out. What I'm doing: 1- open a page with a number that will probably be large 2- get the X Path to where that number is and store it to a variable 3- do a javascript to compare the above stored variable to see if it is bigger than 10, if so, set a new varaible to true; else false (because that is the default value) 4- verify the variable in #3 is true Sounds simple enough, no? Where it goes wrong: At step 3, comparing the variable from step #2 to 10 isn't allowed, at least not the way I'm writing it. Why? Details: <tr> <td>open</td> <td>http://www.google.com/search?hl=en&q=selenium+verifyEval</td> <td></td> </tr> <tr> <td>store</td> <td>/html/body/div[5]/div/p/b[3]</td> <td>resultCount</td> </tr> <tr> <td>storeEval</td> <td>var isMoreThan10 = new Boolean(); isMoreThan10 = (resultCount &gt; 10);</td> <td>isMoreThan10</td> </tr> <tr> <td>verifyExpression</td> <td>${isMoreThan10}</td> <td>true</td> </tr> I just thought of one possible workaround: Exapnd the javascript code to get the value there & assign it to a variable there so I'll be more likely to be able to use that variable in the javascript. Not sure exactly how that would be done- anyone wanna help with that? But surely there is be a better way, isn't there? I must be able to assign a value to a variable in Selenium, then in the next line use that variable in a javascript, right?

• Objective-C: Loop through NSDictionary to create seperate NSArray's

  - by Nic Hubbard

  I have a large NSDictionary structure that I need to loop through and create seperate NSArray's. Here is the structure: ( { id = { text = ""; }; sub = { text = " , "; }; text = ""; "thumb_url" = { text = ""; }; title = { text = "2010-2011"; }; type = { text = "title"; }; }, { id = { text = "76773"; }; sub = { text = "December 13, 2010"; }; text = ""; "thumb_url" = { text = "http://www.puc.edu/__data/assets/image/0004/76774/varieties/thumb.jpg"; }; title = { text = "College Days - Fall 2010"; }; type = { text = "gallery"; }; }, { id = { text = ""; }; sub = { text = ""; }; text = ""; "thumb_url" = { text = ""; }; title = { text = "2009-2010"; }; type = { text = "title"; }; }, { id = { text = "76302"; }; sub = { text = "December 3, 2010"; }; text = ""; "thumb_url" = { text = "http://www.puc.edu/__data/assets/image/0019/76303/varieties/thumb.jpg"; }; title = { text = "Christmas Colloquy"; }; type = { text = "gallery"; }; } ) Each section has a type key, which I need to check. When it finds the "title" key, I need to add those to an array. Then the next sections that would use the "gallery" key needs to be in its own array until it finds another "title" key. Then the "gallery" keys after that into their own array. I am using this a UITableView section titles and content. So, the NSDictionary above should have one NSArray *titles; array, and two other arrays each containing the galleries that came after the title. I have tried using a for loop but I just can't seem to get it right. And ideas would be appreciated.

• Workflow for statistical analysis and report writing

  - by ws

  Does anyone have any wisdom on workflows for data analysis related to custom report writing? The use-case is basically this: Client commissions a report that uses data analysis, e.g. a population estimate and related maps for a water district. The analyst downloads some data, munges the data and saves the result (e.g. adding a column for population per unit, or subsetting the data based on district boundaries). The analyst analyzes the data created in (2), gets close to her goal, but sees that needs more data and so goes back to (1). Rinse repeat until the tables and graphics meet QA/QC and satisfy the client. Write report incorporating tables and graphics. Next year, the happy client comes back and wants an update. This should be as simple as updating the upstream data by a new download (e.g. get the building permits from the last year), and pressing a "RECALCULATE" button, unless specifications change. At the moment, I just start a directory and ad-hoc it the best I can. I would like a more systematic approach, so I am hoping someone has figured this out... I use a mix of spreadsheets, SQL, ARCGIS, R, and Unix tools. Thanks! PS: Below is a basic Makefile that checks for dependencies on various intermediate datasets (w/ ".RData" suffix) and scripts (".R" suffix). Make uses timestamps to check dependencies, so if you 'touch ss07por.csv', it will see that this file is newer than all the files / targets that depend on it, and execute the given scripts in order to update them accordingly. This is still a work in progress, including a step for putting into SQL database, and a step for a templating language like sweave. Note that Make relies on tabs in its syntax, so read the manual before cutting and pasting. Enjoy and give feedback! http://www.gnu.org/software/make/manual/html%5Fnode/index.html#Top R=/home/wsprague/R-2.9.2/bin/R persondata.RData : ImportData.R ../../DATA/ss07por.csv Functions.R $R --slave -f ImportData.R persondata.Munged.RData : MungeData.R persondata.RData Functions.R $R --slave -f MungeData.R report.txt: TabulateAndGraph.R persondata.Munged.RData Functions.R $R --slave -f TabulateAndGraph.R report.txt

• DCVS + hosting for a startup commercial multiplatform phone app

  - by AG

  I'm in lean startup mode, working on a simple phone app that will be published initially as a iThingy app and an Android app with, possibly, Blackberry and Symbian versions to follow. I'm about to go from no repository to needing a central repository that up to 4 very part-time resources will be sharing. Two of us have no version control background, one has used Subversion, and I've used most of the major centralized VCS systems. I'm not going to be pushing the technical limitations of any VCS for a long time; I'm sure that any of the major systems would work fine. And the hosting accounts I've looked at seem reasonable. So I'm really focussed on minimizing the downside risks. That is, I'd like to find a stable setup that is easy to learn in general, easy to use from Windows/Eclipse, and won't paint me into any obvious corners for the next 12 months or so. A quick search of the web had led me to consider the following pairs of DVCS and hosting service, with what I think I'm hearing as their strengths and weaknesses (for my purposes): Bazaar/Launchpad -- My initial choice since I need to get more familiar with this pair for the Google Summer of Code mentoring I'm doing. But, whatever the technical merits, a non-starter for me because they are purely open source, no private repositories plans to purchase that I can see. Git/GitHub -- Git: Fast, light, ultimately flexible, but relatively less Windows friendly, Eclipse plugin (eGit) available but relatively young, GitHub: widely used, pricing is fine Mercurial/BitBucket -- Mercurial: a little less flexible, a little more Windows friendly, Eclipse plugin seems a bit more mature, BitBucket: widely used, pricing is fine, includes a wiki and an issue tracker that we might be able to use instead of something like BaseCamp, at least for a while. Mercurial/BitBucket seem like the winning pair so far for my particular situation; at least two of us are definitely going to be working mostly from Eclipse on Windows and reducing my own learning curve is a priority. ;-) But I have two specific questions: 1) Am I wrong about Bazaar/Launchpad and is there a viable, secure way to use them for proprietary code? 2) Any reason to think that the Mecurial/Bitbucket pair will end up being a headache for my Mac developer, soon, or for Blackberry or Symbian developers a little later? ag

• Various GPS Android Functionality Questions..

  - by Tyler

  Hello - I have a few questions (so far) with the the LocationManager on Android and GPS in general.. Feel free to answer any number of the questions below, and I appreciate your help in advance! (I noticed this stuff doesn't appear to be documented very well, so hopefully these questions will help others out too!) 1) I am using the following code, but I think there may be extra fluff in here that I do not need. Can you tell me if I can delete any of this? LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); LocationListener locationListener = new MyLocationListener(); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener); LocationProvider locationProvider = lm.getProvider("gps"); Location currentLocation = lm.getLastKnownLocation(locationProvider.getName()); 2) Is there a way to hold off on the last step (accessing "getLastKnownLocation" until after I am sure I have a GPS lock? What happens if this is called and GPS is still looking for signal? 3) MOST importantly, I want to ensure I have a GPS lock before I proceed to my next method, so is there a way to check to see if GPS is locked on and getLastKnownLocation is up to date? 4) Is there a way to 'shut down' the GPS listener once it does receive a lock and getLastKnownLocation is updated? I don't see a need to keep this running for my application once I have obtained a lock.. 5) Can you please confirm my assumption that "getLastKnownLocation" is updated frequently as the receiver moves? 6) In my code, I also have a class called "MyLocationListener" (code below) that I honestly just took from another example.. Is this actually needed? I assume this updates my location manager whenever the location changes, but it sure doesn't appear that there is much to the class itself! private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { if (loc != null) { //Toast.makeText(getBaseContext(), "Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show(); } } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } }

• AutoFixture refactoring

  - by Thomas Jaskula

  I started to use AutoFixture http://autofixture.codeplex.com/ as my unit tests was bloated with a lot of data setup. I was spending more time on seting up the data than to write my unit test. Here's an example of how my initial unit test looks like (example taken from cargo application sample from DDD blue book) [Test] public void should_create_instance_with_correct_ctor_parameters() { var carrierMovements = new List<CarrierMovement>(); var deparureUnLocode1 = new UnLocode("AB44D"); var departureLocation1 = new Location(deparureUnLocode1, "HAMBOURG"); var arrivalUnLocode1 = new UnLocode("XX44D"); var arrivalLocation1 = new Location(arrivalUnLocode1, "TUNIS"); var departureDate1 = new DateTime(2010, 3, 15); var arrivalDate1 = new DateTime(2010, 5, 12); var carrierMovement1 = new CarrierMovement(departureLocation1, arrivalLocation1, departureDate1, arrivalDate1); var deparureUnLocode2 = new UnLocode("CXRET"); var departureLocation2 = new Location(deparureUnLocode2, "GDANSK"); var arrivalUnLocode2 = new UnLocode("ZEZD4"); var arrivalLocation2 = new Location(arrivalUnLocode2, "LE HAVRE"); var departureDate2 = new DateTime(2010, 3, 18); var arrivalDate2 = new DateTime(2010, 3, 31); var carrierMovement2 = new CarrierMovement(departureLocation2, arrivalLocation2, departureDate2, arrivalDate2); carrierMovements.Add(carrierMovement1); carrierMovements.Add(carrierMovement2); new Schedule(carrierMovements).ShouldNotBeNull(); } Here's how I tried to refactor it with AutoFixture [Test] public void should_create_instance_with_correct_ctor_parameters_AutoFixture() { var fixture = new Fixture(); fixture.Register(() => new UnLocode(UnLocodeString())); var departureLoc = fixture.CreateAnonymous<Location>(); var arrivalLoc = fixture.CreateAnonymous<Location>(); var departureDateTime = fixture.CreateAnonymous<DateTime>(); var arrivalDateTime = fixture.CreateAnonymous<DateTime>(); fixture.Register<Location, Location, DateTime, DateTime, CarrierMovement>( (departure, arrival, departureTime, arrivalTime) => new CarrierMovement(departureLoc, arrivalLoc, departureDateTime, arrivalDateTime)); var carrierMovements = fixture.CreateMany<CarrierMovement>(50).ToList(); fixture.Register<List<CarrierMovement>, Schedule>((carrierM) => new Schedule(carrierMovements)); var schedule = fixture.CreateAnonymous<Schedule>(); schedule.ShouldNotBeNull(); } private static string UnLocodeString() { var stringBuilder = new StringBuilder(); for (int i = 0; i < 5; i++) stringBuilder.Append(GetRandomUpperCaseCharacter(i)); return stringBuilder.ToString(); } private static char GetRandomUpperCaseCharacter(int seed) { return ((char)((short)'A' + new Random(seed).Next(26))); } I would like to know if there's better way to refactor it. Would like to do it shorter and easier than that.
