• Inserting new <TD> elements into a table row.

  - by Hunter S. Smythe

  I have created a small application written in XHTML, JavaScript/JQuery and PHP. The PHP reads and writes to a small SQLite database. How would i go about inserting cells into a pre-scripted table. The cells would need to be configured using some information from my database. For example, below are two cells with their data retrieved from my database: Cell One Starts: 120px; Finishes: 180px; Background: Blue; Cell Two Starts: 240px; Finishes: 300px; Background: Green; On my table row, it is 500px in width. How would I insert the cells above into the row. In this example, the first cell would start 120px into the row and have a width of 180px. The second cell would start 240px into the row and have a width of 300px. I just cant seem to work out a way of doing this, any ideas would be very helpful. Thank you for any input, all is appreciated. Hunter.

• Testing fault tolerant code

  - by Robert

  I’m currently working on a server application were we have agreed to try and maintain a certain level of service. The level of service we want to guaranty is: if a request is accepted by the server and the server sends on an acknowledgement to the client we want to guaranty that the request will happen, even if the server crashes. As requests can be long running and the acknowledgement time needs be short we implement this by persisting the request, then sending an acknowledgement to the client, then carrying out the various actions to fulfill the request. As actions are carried out they too are persisted, so the server knows the state of a request on start up, and there’s also various reconciliation mechanisms with external systems to check the accuracy of our logs. This all seems to work fairly well, but we have difficult saying this with any conviction as we find it very difficult to test our fault tolerant code. So far we’ve come up with two strategies but neither is entirely satisfactory: Have an external process watch the server code and then try and kill it off at what the external process thinks is an appropriate point in the test Add code the application that will cause it to crash a certain know critical points My problem with the first strategy is the external process cannot know the exact state of the application, so we cannot be sure we’re hitting the most problematic points in the code. My problem with the second strategy, although it gives more control over were the fault takes, is I do not like have code to inject faults within my application, even with optional compilation etc. I fear it would be too easy to over look a fault injection point and have it slip into a production environment.

• A copy of ApplicationController has been removed from the module tree but is still active

  - by Matchu

  Whenever two concurrent HTTP requests go to my Rails app, the second always returns the following error: A copy of ApplicationController has been removed from the module tree but is still active! From there it gives an unhelpful stack trace to the effect of "we went through the standard server stuff, ran your first before_filter on ApplicationController (and I checked; it's just whichever filter runs first)", then offers the following: /home/matchu/rails/torch/vendor/rails/activesupport/lib/active_support/dependencies.rb:414:in `load_missing_constant' /home/matchu/rails/torch/vendor/rails/activesupport/lib/active_support/dependencies.rb:96:in `const_missing' which I'm assuming is a generic response and doesn't really say much. Google seems to tell me that people developing Rails Engines will encounter this, but I don't do that. All I've done is upgrade my Rails app from 2.2 (2.1?) to 2.3. What are some possible causes for this error, and how can I go about tracking down what's really going on? I know this question is vague, so would any other information be helpful? More importantly: I tried doing a test run in a "production" environment just now, and the error doesn't seem to persist. Does this only affect development, then, and need I not worry too much?

• improving data extraction from text file in Java

  - by owca

  I have CSV file with sample data in this form : 220 30 255 0 0 Javascript 200 20 0 255 128 Thinking in java , where the first column is height, second thickness, next three are rgb values for color and last one is title. All need to be treated as separate variables. I have already written my own solution for this, but I'm wondering if there are no better/easier/shorter ways of doing this. Extracted data will then be used to create Book object, throw every Book into array of books and print it with swing. Here's the code : private static Book[] addBook(Book b, Book[] bookTab){ Book[] tmp = bookTab; bookTab = new Book[tmp.length+1]; for(int i = 0; i < tmp.length; i++){ bookTab[i] = tmp[i]; } bookTab[tmp.length] = b; return bookTab; } public static void main(String[] args) { Book[] books = new Book[0]; try { BufferedReader file = new BufferedReader(new FileReader("K:\\books.txt")); String s; while ((s = file.readLine()) != null) { int hei, thick, R, G, B; String tit; hei = Integer.parseInt(s.substring(0, 3).replaceAll(" ", "")); thick = Integer.parseInt(s.substring(4, 6).replaceAll(" ", "")); R = Integer.parseInt(s.substring(10, 13).replaceAll(" ", "")); G = Integer.parseInt(s.substring(14, 17).replaceAll(" ", "")); B = Integer.parseInt(s.substring(18, 21).replaceAll(" ", "")); tit = s.substring(26); System.out.println(tyt+wys+grb+R+G+B); books = addBook(new Book(wys, grb, R, G, B, tyt),books); } file.close(); } catch (IOException e) { //do nothing } }

• Getter and Setter vs. Builder strategy

  - by Extrakun

  I was reading a JavaWorld's article on Getter and Setter where the basic premise is that getters expose internal content of an object, hence tightening coupling, and go on to provide examples using builder objects. I was rather leery of abolishing getter/setter but on second reading of the article, see to quite like the idea. However, sometimes I just need one cruical element of an entity class, such as the user's id and writing one whole class just to extract that cruical element seems like overkill. It also implies that for different view, a different type of importer/exporter must be implemented (or the whole data of the class to be exported out, thus resulting in waste). Usually I tend towards filtering the result of a getter - for example, if I need to output the price of a product in different currency, I would code it as: return CurrencyOutput::convertTo($product->price(), 'USD'); This is with the understanding that the raw output of a getter is not necessary the final result to be pushed onto a screen or a database. Is getter/setter really as bad as it is protrayed to be? When should one adopt a builder strategy, or a 'get the result and filter it' approach? How do you avoid having a class needing to know about every other objects if you are not using getter/setter?

• How to unit test this simple ASP.NET MVC controller

  - by Frank Schwieterman

  Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case). How would you test this? (either the first or second link) My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing. The controller: public class TestController : Controller { public ActionResult Foo() { ViewData["Link2"] = Url.Action("Bar"); return View("Foo"); } public ActionResult Bar() { return View("Bar"); } } the "Foo" view: <%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage" MasterPageFile="~/Views/Shared/Site.Master"%> <asp:Content ContentPlaceHolderID="MainContent" runat="server"> <%= Html.ActionLink("link 1", "Bar") %> <a href="<%= ViewData["Link2"]%>">link 2</a> </asp:Content>

• MS Access: Why is ADODB.Recordset.BatchUpdate so much slower than Application.ImportXML?

  - by apenwarr

  I'm trying to run the code below to insert a whole lot of records (from a file with a weird file format) into my Access 2003 database from VBA. After many, many experiments, this code is the fastest I've been able to come up with: it does 10000 records in about 15 seconds on my machine. At least 14.5 of those seconds (ie. almost all the time) is in the single call to UpdateBatch. I've read elsewhere that the JET engine doesn't support UpdateBatch. So maybe there's a better way to do it. Now, I would just think the JET engine is plain slow, but that can't be it. After generating the 'testy' table with the code below, I right clicked it, picked Export, and saved it as XML. Then I right clicked, picked Import, and reloaded the XML. Total time to import the XML file? Less than one second, ie. at least 15x faster. Surely there's an efficient way to insert data into Access that doesn't require writing a temp file? Sub TestBatchUpdate() CurrentDb.Execute "create table testy (x int, y int)" Dim rs As New ADODB.Recordset rs.CursorLocation = adUseServer rs.Open "testy", CurrentProject.AccessConnection, _ adOpenStatic, adLockBatchOptimistic, adCmdTableDirect Dim n, v n = Array(0, 1) v = Array(50, 55) Debug.Print "starting loop", Time For i = 1 To 10000 rs.AddNew n, v Next i Debug.Print "done loop", Time rs.UpdateBatch Debug.Print "done update", Time CurrentDb.Execute "drop table testy" End Sub I would be willing to resort to C/C++ if there's some API that would let me do fast inserts that way. But I can't seem to find it. It can't be that Application.ImportXML is using undocumented APIs, can it?

• Invert linear linked list

  - by ArtWorkAD

  Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

• JQuery - nested ul/li list, keep expanded after reload of page

  - by H4mm3rHead

  Hi, I have a nested ul/li list <ul> <li>first</li> <li>second <ul> <li>Third</li> </ul> </li> ... and so on I found this JQuery on the interweb to use as inspiration, but how to keep the one item i expanded open after the page has reloaded? <script type="text/javascript"> $(document).ready(function() { $('div#sideNav li li > ul').hide(); //hide all nested ul's $('div#sideNav li > ul li a[class=current]').parents('ul').show().prev('a').addClass('accordionExpanded'); //show the ul if it has a current link in it (current page/section should be shown expanded) $('div#sideNav li:has(ul)').addClass('accordion'); //so we can style plus/minus icons $('div#sideNav li:has(ul) > a').click(function() { $(this).toggleClass('accordionExpanded'); //for CSS bgimage, but only on first a (sub li>a's don't need the class) $(this).next('ul').slideToggle('fast'); $(this).parent().siblings('li').children('ul:visible').slideUp('fast') .parent('li').find('a').removeClass('accordionExpanded'); return true; }); }); </script>

• Using NHibernate to select entities based on activity of children entities

  - by mannish

  I'm having a case of the Mondays... I need to select blog posts based on recent activity in the post's comments collection (a Post has a List<Comment> property and likewise, a Comment has a Post property, establishing the relationship. I don't want to show the same post twice, and I only need a subset of the entities, not all of the posts. First thought was to grab all posts that have comments, then order those based on the most recent comment. For this to work, I'm pretty sure I'd have to limit the comments for each Post to the first/newest Comment. Last I'd simply take the top 5 (or whatever max results number I want to pass into the method). Second thought would be to grab all of the comments, ordered by CreatedOn, and filter so there's only one Comment per Post. Then return those top (whatever) posts. This seems like the same as the first option, just going through the back door. I've got an ugly, two query option I've got working with some LINQ on the side for filtering, but I know there's a more elegant way to do it in using the NHibernate API. Hoping to see some good ideas here.

• Erlang, SSH and authorized_keys

  - by Roberto Aloi

  Playing with the ssh and public_key application in Erlang, I've discovered a nice feature. I was trying to connect to my running Erlang SSH daemon by using a rsa key, but the authentication was failing and I was prompted for a password. After some debugging and tracing (and a couple of coffees), I've realized that, for some weird reason, a non valid key for my user was there. The authorized_keys file contained two keys. The wrong one was at some point in the file, while the correct one was appended at the end of the file. Now, the Erlang SSH application, when diffing the provided key with the ones contained in the authorized_keys, it was finding the first entry (completely ignoring the second on - the correct one). Then, it was switching to different authentication mechanism (at first it was trying dsa instead of rsa and then it was prompting for a password). The question is: Is this behavior intended or should the SSH server check for multiple entries for the same user in the *authorized_keys* file? Is this a generic SSH behaviour or it's just specific to the Erlang implementation?

• Random String Generator creates same string on multiple calls

  - by rockinthesixstring

  Hi there. I've build a random string generator but I'm having a problem whereby if I call the function multiple times say in a Page_Load method, the function returns the same string twice. here's the code ''' <summary>' ''' Generates a Random String' ''' </summary>' ''' <param name="n">number of characters the method should generate</param>' ''' <param name="UseSpecial">should the method include special characters? IE: # ,$, !, etc.</param>' ''' <param name="SpecialOnly">should the method include only the special characters and excludes alpha numeric</param>' ''' <returns>a random string n characters long</returns>' Public Function GenerateRandom(ByVal n As Integer, Optional ByVal UseSpecial As Boolean = True, Optional ByVal SpecialOnly As Boolean = False) As String Dim chars As String() ' a character array to use when generating a random string' Dim ichars As Integer = 74 'number of characters to use out of the chars string' Dim schars As Integer = 0 ' number of characters to skip out of the characters string' chars = { _ "A", "B", "C", "D", "E", "F", _ "G", "H", "I", "J", "K", "L", _ "M", "N", "O", "P", "Q", "R", _ "S", "T", "U", "V", "W", "X", _ "Y", "Z", "0", "1", "2", "3", _ "4", "5", "6", "7", "8", "9", _ "a", "b", "c", "d", "e", "f", _ "g", "h", "i", "j", "k", "l", _ "m", "n", "o", "p", "q", "r", _ "s", "t", "u", "v", "w", "x", _ "y", "z", "!", "@", "#", "$", _ "%", "^", "&", "*", "(", ")", _ "-", "+"} If Not UseSpecial Then ichars = 62 ' only use the alpha numeric characters out of "char"' If SpecialOnly Then schars = 62 : ichars = 74 ' skip the alpha numeric characters out of "char"' Dim rnd As New Random() Dim random As String = String.Empty Dim i As Integer = 0 While i < n random += chars(rnd.[Next](schars, ichars)) System.Math.Max(System.Threading.Interlocked.Increment(i), i - 1) End While rnd = Nothing Return random End Function but if I call something like this Dim str1 As String = GenerateRandom(5) Dim str2 As String = GenerateRandom(5) the response will be something like this g*3Jq g*3Jq and the second time I call it, it will be 3QM0$ 3QM0$ What am I missing? I'd like every random string to be generated as unique.

• PocketPC c++ windows message processing recursion problem

  - by user197350

  Hello, I am having a problem in a large scale application that seems related to windows messaging on the Pocket PC. What I have is a PocketPC application written in c++. It has only one standard message loop. while (GetMessage (&msg, NULL, 0, 0)) { { TranslateMessage (&msg); DispatchMessage (&msg); } } We also have standard dlgProc's. In the switch of the dlgProc, we will call a proprietary 3rd party API. This API uses a socket connection to communicate with another process. The problem I am seeing is this: whenever two of the same messages come in quickly (from the user clicking the screen twice too fast and shouldn't be) it seems as though recursion is created. Windows begins processing the first message, gets the api into a thread safe state, and then jumps to process the next (identical ui) message. Well since the second message also makes the API call, the call fails because it is locked. Because of the design of this legacy system, the API will be locked until the recursion comes back out (which also is triggered by the user; so it could be locked the entire working day). I am struggling to figure out exactly why this is happening and what I can do about it. Is this because windows recognizes the socket communication will take time and preempts it? Is there a way I can force this API call to complete before preemption? Is there a way I can slow down the message processing or re-queue the message to ensure the first will execute (capturing it and doing a PostMessage back to itself didnt work). We don't want to lock the ui down while the first call completes. Any insight is greatly appreciated! Thanks!!

• MS Access Interop - How to set print filename?

  - by Ryan

  Hi all, I'm using Delphi 2009 and the MS Access Interop COM API. I'm trying to figure out two things, but one is more important than the other right now. I need to know how to set the file name when sending the print job to the spooler. Right now it's defaulting to the Access DB's name, which can be something different than the file's name. I need to just ensure that when this is printed it enters the print spool using the same filename as the actual file itself - not the DB's name. My printer spool is actually a virtual print driver that converts documents to an image. That's my main issue. The second issue is how to specify which printer to use. This is less important at the moment because I'm just using the default printer for now. It would be nice if I could specify the printer to use, though. Does anyone know either of these two issues? Thank you in advance. I'll go ahead and paste my code: unit Converter.Handlers.Office.Access; interface uses sysutils, variants, Converter.Printer, Office_TLB, Access_TLB, UDC_TLB; procedure ToTiff(p_Printer: PrinterDriver; p_InputFile, p_OutputFile: String); implementation procedure ToTiff(p_Printer: PrinterDriver; p_InputFile, p_OutputFile: String); var AccessApp : AccessApplication; begin AccessApp := CoAccessApplication.Create; AccessApp.Visible := False; try AccessApp.OpenCurrentDatabase(p_InputFile, True, ''); AccessApp.RunCommand(acCmdQuickPrint); AccessApp.CloseCurrentDatabase; finally AccessApp.Quit(acQuitSaveNone); end; end; end.

• Will IntelliTrace(tm) (historical debugging) be available for unmanaged c++ in future versions of Vi

  - by Tim

  I love the idea of historical debugging in VS 2010. However, I am really disappointed that unmanaged C++ is left out. IntelliTrace supports debugging Visual Basic and C# applications that use .NET version 2.0, 3.0, 3.5, or 4. You can debug most applications, including applications that were created by using ASP.NET, Windows Forms, WPF, Windows Workflow, and WCF. IntelliTrace does not support debugging C++, script, or other languages. Debugging of F# applications is supported on an experimental basis. (editorial) [This is really poor support in my opinion. .NET is less in need of this assistance than unmanaged c++. I an getting a little tired of the status of plain old C++ and its second-class status in the MS tools world. Yes, I realize it is probably WAAY easier to implement this with .NET and MS are pushing .NET as the future, and yes, I know that C++ is an "old" language, but that does not diminish the fact that there are lots of C++ apps out there and there will continue to be more apps built with C++. I sincerely hope MS has not dropped C++ as a supported developer tool/language- that would be a shame.] Does anyone know if there are plans for it to support C++?

• How do I break down MySQL query results into categories, each with a specific number of rows?

  - by Mel

  Hello, Problem: I want to list n number of games from each genre (order not important) The following MySQL query resides inside a ColdFusion function. It is meant to list all games under a platform (for example, list all PS3 games; list all Xbox 360 games; etc...). The variable for PlatformID is passed through the URL. I have 9 genres, and I would like to list 10 games from each genre. SELECT games.GameID AS GameID, games.GameReleaseDate AS rDate, titles.TitleName AS tName, titles.TitleShortDescription AS sDesc, genres.GenreName AS gName, platforms.PlatformID, platforms.PlatformName AS pName, platforms.PlatformAbbreviation AS pAbbr FROM (((games join titles on((games.TitleID = titles.TitleID))) join genres on((genres.GenreID = games.GenreID))) join platforms on((platforms.PlatformID = games.PlatformID))) WHERE (games.PlatformID = '#ARGUMENTS.PlatformID#') ORDER BY GenreName ASC, GameReleaseDate DESC Once the query results come back I group them in ColdFusion as follows: <cfoutput query="ListGames" group="gName"> (first loop which lists genres) #ListGames.gName# <cfoutput> (nested loop which lists games) #ListGames.tName# </cfoutput> </cfoutput> The problem is that I only want 10 games from each genre to be listed. If I place a "limit" of 50 in the SQL, I will get ~ 50 games of the same genre (depending on how much games of that genre there are). The second issue is I don't want the overload of querying the database for all games when each person will only look at a few. What is the correct way to do this? Many thanks!

• Delphi Application using COMMIT and ROLLBACK for Multiple SQL Updates

  - by Matt

  Is it possible to use the SQL BEGIN TRANSACTION, COMMIT TRANSACTION, ROLLBACK TRANSACTION when embedding SQL Queries into an application with mutiple calls to the SQL for Table Updates. For example I have the following code: Q.SQL.ADD(<UPDATE A RECORD>); Q.ExecSQL; Q.Close; Q.SQL.Clear; Q.SQL.ADD(<Select Some Data>); Q.Open; Set Some Variables Q.Close; Q.SQL.Clear; Q.SQL.ADD(<UPDATE A RECORD>); Q.ExecSQL; What I would like to do is if the second update fails I want to roll back the first transaction. If I set a unique notation for the BEGIN, COMMIT, ROLLBACK so as to specify what is being committed or rolled back, is it feasible. i.e. before the first Update specify BEGIN TRANSACTION_A then after the last update specify COMMIT TRANSACTION_A I hope that makes sense. If I was doing this in a SQL Stored Procedure then I would be able to specify this at the start and end of the procedure, but I have had to break the code down into manageable chunks due to process blocks and deadlocks on a heavy loaded SQL Server.

• How do I get my code to read the spaces between longs?

  - by WahtsUpWorld

  I apologize for any inconvenience that may occur in answering my question, I'm fairly new to programming and I'm so far only in the last weeks of my community college Java I class.

• Cascading input control is empty while accessing a Jasper Report

  - by Yogesh R

  I call a jasper report through an independent URL through which I pass one of the input controls needed to run the report. E.g. http:// localhost:8080/jasperserver/flow.html?_flowId=viewReportFlow&standAlone=true&reportUnit=xyz&ParentFolderUri=abcd&j_username=xyz&j_password=xyz&parameter1=value1& . . . As you can see in the URL, I pass the JasperServer username and password, reportUnit name and location and other mandatory parameters, along with the report input parameter, i.e., "parameter1" which can have a value like "value1". I used a mandatory, read-only and visible input control for this input value. Its value would come from the URL, showed in the box but was read-only and hence could not be changed. The report was working absolutely fine upto this point. But the tragedy began when my client rejected this idea. He wanted a completely invisible input control to my report and the input value would be passed through the URL, just like illustrated above. And then my client asked me to refer to this and made me work on cascading input controls. Recently I added a cascading input control to this report. The input control type is a single select query, which utilizes two parameters that I pass to the report through the URL. Now when the Jasper server responds to the URL with the input parameters, all the other static parameters work properly, except for the cascaded one. When I click the select box of the cascaded input, I can see the desired options for a second, and then, it just goes empty while I'm viewing the select list. But when I make the "Parameter1" input control visible, the cascading input control works! And then I turn in invisible, the cascading input control turns into a beast that does things by itself and not listen to his master. I am not able to understand why this is happening. Could anybody please provide me a solution to this?

• Converting timestamp to time ago in php e.g 1 day ago, 2 days ago...

  - by cosmicbdog

  hi everyone, i am trying to convert a timestamp of the format: 2009-09-12 20:57:19 and turn it into something like '3 minutes ago' with php. I found a useful script to do this, but I think its looking for a different format to be used as the time variable. The script I'm wanting to modify to work with this format is: function _ago($tm,$rcs = 0) { $cur_tm = time(); $dif = $cur_tm-$tm; $pds = array('second','minute','hour','day','week','month','year','decade'); $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600); for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]); $no = floor($no); if($no <> 1) $pds[$v] .='s'; $x=sprintf("%d %s ",$no,$pds[$v]); if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0)) $x .= time_ago($_tm); return $x; } I think on those first few lines its trying to do something that looks like this (different date format math): $dif = 1252809479 - 2009-09-12 20:57:19; How would I go about converting my timestamp into that (unix?) format?

• Awk filtering values between two files when regions intersect (any solutions welcome)

  - by user964689

  This is building upon an earlier question Awk conditional filter one file based on another (or other solutions) I have an awk program that outputs a column from rows in a text file 'refGene.txt if values in that row match 2 out of 3 values in another text file. I need to include an additional criteria for finding a match between the two files. The criteria is inclusion if the range of the 2 numberical values specified in each row in file 1 overlap with the range of the two values in a row in refGene.txt. An example of a line in File 1: chr1 10 20 chr2 10 20 and an example line in file 2(refGene.txt) of the matching columns ($3, $5, $ 6): chr1 5 30 Currently the awk program does not treat this as a match because although the first column matches neither the 2nd or 3rd columns do no. But I would like a way to treat this as a match because the region 10-20 in file 1 is WITHIN the range of 5-30 in refGene.txt. However the second line in file 1 should NOT match because the first column does not match, which is necessary. If there is a way to include cases when any of the range in file 1 overlaps with any of the range in refGene.txt that would be really helpful. It should also replace the below conditional statements as it would also find all the cases currently described below. Please let me know if my question is unclear. Any help is really appreciated, thanks it advance! (solutions do not have to be in awk) Rubal FILES=/files/*txt for f in $FILES ; do awk ' BEGIN { FS = "\t"; } FILENAME == ARGV[1] { pair[ $1, $2, $3 ] = 1; next; } { if ( pair[ $3, $5, $6 ] == 1 ) { print $13; } } ' $(basename $f) /files/refGene.txt > /files/results/$(basename $f) ; done

• accessing parsed JSON on the iPhone SDK

  - by itai alter

  Hello All! I've been following the great tutorial about (iPhone, json and Flickr API and I did manage to access the parsed json info just fine. Now I'm trying to do the same thing with the Twitter API, and I am able to get the json info and parse it, but I can't seem to access it like in Flickr. I noticed that the json info that is retrieved from Twitter is a little different from Flickr. The Flickr json info starts straight with a curly braces ({), while the Twitter json info starts with a square bracket and then a curly braces ([{). I understand that it means it's an array inside the json info, but I don't know how to access it. In the Flickr example, I access the objects like so (the second line takes the number of pages Flickr has reported): NSDictionary *results = [jsonString JSONValue]; pagesString = [[results objectForKey:@"photos"] objectForKey:@"pages"]; but I can't seem to access the Twitter response in the same way... Does anyone know of a solution? (here's an example of the Twitter JSON response: api.twitter.com/1/statuses/public_timeline.json ) Thanks a bunch!

• Subquery max sequence number

  - by Andy Levesque

  I'm hesitant to ask because I'm sure it's out there, but I just can't seem to come up with the keywords to find the answer. I'm stepping outside my boundaries by starting with subqueries (normally an Access user). I have a query that has TECH_ID, SEQ_NBR, and PELL_FT_AWD_AMT SELECT ISRS_V_NEED_ANAL_RESULT_PARENT.TECH_ID, ISRS_V_NEED_ANAL_RESULT_PARENT.AWD_YR, ISRS_V_NEED_ANAL_RESULT_PARENT.PELL_FT_AWD_AMT, ISRS_V_NEED_ANAL_RESULT_PARENT.SEQ_NBR FROM ISRS_V_NEED_ANAL_RESULT_PARENT GROUP BY ISRS_V_NEED_ANAL_RESULT_PARENT.TECH_ID, ISRS_V_NEED_ANAL_RESULT_PARENT.AWD_YR, ISRS_V_NEED_ANAL_RESULT_PARENT.PELL_FT_AWD_AMT, ISRS_V_NEED_ANAL_RESULT_PARENT.SEQ_NBR HAVING (((ISRS_V_NEED_ANAL_RESULT_PARENT.AWD_YR)="2013")) ORDER BY ISRS_V_NEED_ANAL_RESULT_PARENT.TECH_ID; What I want to return is add a subquery that selects only the max SEQ_NUM for each record, but I can't seem to get the syntax right. In the past I would cheat and have a separate query that first gave me the TECH_ID and max SEQ_NUM, and then have a second query that use the original table and the first query in a join to get the rest. How can I do this in one query? Example: TECH_ID SEQ_NUM PELL 1 1 4000 1 2 4000 1 3 5000 Using just the max of the sequence number still returns: 1; 2; 4000 and 1; 3; 5000 when I'm only wanting the latter.
