• Using mod_rewrite for a RESTful api

  - by razass

  Say the user is making a request to the following url: "http://api.example.com/houses/123/abc" That request needs to map to "/webroot/index.php" and 'houses', '123', 'abc' need to be able to be parsed out of the URL in that index.php. It also can't alter the http headers or body. There can be any number of variables after the domain ie) "http://api.example.com/houses/1234/abc/zxy/987" I think I already have all requests being sent to webroot using: <IfModule mod_rewrite.c> RewriteEngine on RewriteCond $0 !^webroot/ RewriteRule .* webroot/$0 [L] </IfModule> Which appears to be working but I am not sure if it is correct. But now I am at a loss as to how to take the next step as mentioned above. Thanks in advance!

• Copy & Paste Images Wiki functionality?

  - by Jakub

  I was discussing this with some coworkers, they would like a wiki, but are turned off by the need to constantly [browse] and [upload] files. They like the functionality of Lotus Notes that they can copy & paste screenshots (or crops etc) directly into Notes databases / libraries. But they are not fans of Lotus notes behond that (performance, etc,) Anyone work with a free (open source hopefully) wiki of documenting application that just allows copy & paste of text & image content? Would be great to have one internally installed that we could use for documentation without constantly uploading/attaching files. Not sure if I am asking for functionality that is not available in a browser.

• PhpMyAdmin Hangs On MySQL Error

  - by user75228

  I'm currently running PhpMyAdmin 4.0.10 (the latest version supporting PHP 4.2.X) on my Amazon EC2 connecting to a MySQL database on RDS. Everything works perfectly fine except actions that return a mysql error message. Whether I perform "any" kind of action that will return a mysql error, Phpmyadmin will hang with the yellow "Loading" box forever without displaying anything. For example, if I perform the following command in MySQL CLI : select * from 123; It instantly returns the following error : ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '123' at line 1 which is completely normal because table 123 doesn't exist. However, if I execute the exact same command in the "SQL" box in Phpmyadmin, after I click "Go" it'll display "Loading" and stops there forever. Has anyone ever encountered this kind of issue with Phpmyadmin? Is this a bug or I have something wrong with my config.inc.php? Any help would be much appreciated. I also noticed these error messages in my apache error logs : /opt/apache/bin/httpd: symbol lookup error: /opt/php/lib/php/extensions/no-debug-non-zts-20060613/iconv.so: undefined symbol: libiconv_open /opt/apache/bin/httpd: symbol lookup error: /opt/php/lib/php/extensions/no-debug-non-zts-20060613/iconv.so: undefined symbol: libiconv_open /opt/apache/bin/httpd: symbol lookup error: /opt/php/lib/php/extensions/no-debug-non-zts-20060613/iconv.so: undefined symbol: libiconv_open Below are my config.inc.php settings : <?php /* vim: set expandtab sw=4 ts=4 sts=4: */ /** * phpMyAdmin sample configuration, you can use it as base for * manual configuration.

• Where does the convention come from to use F9 for refresh?

  - by iconoclast

  Although in Windows F5 is the common (though not at all mnemonically appropriate!) keystroke to refresh the contents of a window, I've seen at least two different applications that use F9. One is the much-maligned Lotus Notes (which is actually quite good if you can overlook the abysmal user interface ;), and the other is muCommander. Since Lotus Notes has other non-standard conventions that apparently are borrowed from other places (such as Esc to close a Window) and because it's unlikely to be a source of influence for many applications, I'm betting both apps borrow from a common source (even if indirectly). What is that source? Where does F9 as the refresh key come from?

• IE7 is making my life miserable! Getting gaps between html table columns (w/ colspan) with css togg

  - by Art Peterson

  Copy/paste this html code snippet and try it out in IE7. When you toggle the hidden columns it leaves a gap between the columns. In Firefox it works fine, the columns touch when minimized. Haven't tried IE8 yet, would be curious to hear how it works there. Any ideas? I've tried a bunch of things in the CSS like table-layout:fixed but no luck. Note: Not looking for a different toggling method because the table I'm really dealing with is 50+ columns wide and 4000+ rows so looping/jquery techniques are too slow. Here's the code - if someone can re-post a working version of it I'll instantly give them the check and be forever in your debt! <DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <script> function toggle() { var tableobj = document.getElementById("mytable"); if (tableobj.className == "") { tableobj.className = "hide1 hide2"; } else { tableobj.className = ""; } } </script> <style> table { border-collapse: collapse; } td, th { border: 1px solid silver; } .hide1 .col1 { display: none; } .hide2 .col2 { display: none; } </style> </head> <body> <input type="button" value="toggle" onclick="toggle();" /> <table id="mytable"> <tr> <th>A</th> <th colspan="2">B</th> <th colspan="2" class="col1">B1</th> <th colspan="2">C</th> <th colspan="2" class="col2">C1</th> </tr> <tr> <td>123</td> <td>456</td> <td>789</td> <td class="col1">123</td> <td class="col1">456</td> <td>789</td> <td>123</td> <td class="col2">456</td> <td class="col2">789</td> </tr> </table> </body> </html>

• DATE function does not support all the dates in DAX by design #powerpivot #tabular #dax

  - by Marco Russo (SQLBI)

  The DATE function in DAX has this simple syntax: DATE( <year>, <month>, <day> ) If you are like me, you never read the BOL notes that says in a clear way that it supports dates beginning with March 1, 1900. In fact, I was wrongly assuming that it would have supported any date that can be represented in a Date data type in Data Models, so all the dates beginning with January 1, 1900. The funny thing is that in some of the BOL documentation you will find that Date data type supports dates after March 1, 1900 (which seems not including that date, but this is a detail…). But we should not digress. The real issue is that if you try to call the DATE function passing values between January 1 and February 28, 1900, you will see a different day as a result. evaluate row ( "x", DATE( 1900, 1, 1 ) ) -- return WRONG result -- [x] 12/31/1899 12:00:00 AM   evaluate row ( "x", DATE( 1901, 2, 29 ) ) -- return WRONG result -- [x] 2/28/1900 12:00:00 AM   evaluate row ( "x", DATE( 1900, 3, 1 ) ) -- return CORRECT result -- [x] 3/1/1900 12:00:00 AM As usual, this is not a bug. It is “by design”. The DATE function works in this way in Excel. And also in Excel it was “by design”. In this case the design is having the same bug of Lotus 1-2-3 that handled 1900 a leap year, even though it isn’t. The first release of Lotus 1-2-3 is dated 1983. I hope many of my readers are younger than that. I tried to open a bug in Connect. Please vote it. I would like if Microsoft changed this type of items from “by design” (as we can expect) to “by genetic disease”. Or by “historical respect”, in order to be more politically correct.

• Getting Internal Name of a Share Point List Fields

  - by Gino Abraham

  Over the last 2 weeks i was developing a tool to migrate Lotus notes data base to Share point. The mapping between Lotus notes schema and share point list schema was done manually in an xml file for out tool. To map the columns we wanted internal names of each field. There are quite a few ways to achieve this, have explained few below. If you want internal names for one or 2 columns you can do so by navigating to the list setting and clicking on the column name. Once you are in column's details, you can check the query string of the page. The last item in the query string would be field's internal. Replace all "%5f" with '_' will give you the field internal name. In my case there were more than 80 columns. I used power shell to get the list of columns with details. Open windows Powershell and paste the following script after modifying the url and list name. [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") $site = new-object Microsoft.SharePoint.SPSite(http://yousitecolurl) $web = $site.OpenWeb() $list = $web.Lists["yourlist name"] $list.Fields | Format-Table Title, InternalName, TypeAsString I also found a tool in Codeplex.com which can generate a wrapper class for a list. The wrapper class will give you the guid and internal name for all fields in the list.  You can download the tool from http://imtech.codeplex.com/ Just enter the url in the text box and hit open. All the site content will be listed at the left hand side, expand the list, right click and select generate wrapper class.

• ASP.NET website deployment [on hold]

  - by Rei Brazilva

  I am getting my hands wet with ASP and I have been following the tutorials. I deployed the site and in Azure and it worked great. Today I started actually designing the site. And when I published, it looks as if it doesn't read any of the files I just updated, added, and modified. It works on my localhost, but not in the Azure. I thought when you publish, everything goes up, including the new files. I don't have enough reputation to add a picture so, you'll forgive me. SO, basically, how do I get my entire site uploaded? In case anyone does stop by, I was able to pull this out just recently: CA0058 Error Running Code Analysis CA0058 : The referenced assembly 'DotNetOpenAuth.AspNet, Version=4.0.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246' could not be found.

• CSV Anyone?

  - by Tim Dexter

  CSV, a dead format? With today's abilities to generate Excel output (Im working on some posts for the shiny new Excel templates) and the sophistication of the eText outputs, do you really need CSV? I guess so seeing as it was added after the base product was released as an enhancement. But I'd be interested in hearing use cases? I used to think the same of text output. But now Im working in the public sector where older technologies abound I can see a use for text output. Its also used as a machine readable format, etc. BIP still does not support a text format from its RTF templates but its very doable using XSL templates. Back to CSV, I noticed an enhancement in the big list of new stuff in the 10.1.3.4.1 rollup. You can now generate CSV from structured data ie a data template or a SQL XML query. This piqued my interest so I ran off a data template to CSV. Its interesting, in a geeky kinda way, I guess Im that way inclined.Here's my data structure:<EMPLOYEES> <LIST_G_DEPT> <G_DEPT>  <DEPARTMENT_ID>10</DEPARTMENT_ID>  <DEPARTMENT_NAME>Administration</DEPARTMENT_NAME>  <LIST_G_EMP>   <G_EMP>     <EMPLOYEE_ID>200</EMPLOYEE_ID>     <EMP_NAME>Jennifer Whalen</EMP_NAME>     <EMAIL>JWHALEN</EMAIL>     <PHONE_NUMBER>515.123.4444</PHONE_NUMBER>     <HIRE_DATE>1987-09-17T00:00:00.000-06:00</HIRE_DATE>     <SALARY>4400</SALARY>    </G_EMP>   </LIST_G_EMP>  <TOTAL_EMPS>1</TOTAL_EMPS>  <TOTAL_SALARY>4400</TOTAL_SALARY>  <AVG_SALARY>4400</AVG_SALARY>  <MAX_SALARY>4400</MAX_SALARY>  <MIN_SALARY>4400</MIN_SALARY> </G_DEPT>Poor ol Jennifer, she needs some help in the Admin department :0)Pushing this to CSV and BP completely flattens the data out so you get a completely denormalized data output in the CSV.TOTAL_SALARY,DEPARTMENT_ID,DEPARTMENT_NAME,MIN_SALARY,AVG_SALARY,MAX_SALARY,EMPLOYEE_ID,SALARY,PHONE_NUMBER,HIRE_DATE,EMP_NAME,EMAIL,TOTAL_EMPS4400,10,Administration,4400,4400,4400,200,4400,515.123.4444,1987-09-17T00:00:00.000-06:00,"Jennifer Whalen",JWHALEN,119000,20,Marketing,6000,9500,13000,201,13000,515.123.5555,1996-02-17T00:00:00.000-07:00,"Michael Hartstein",MHARTSTE,219000,20,Marketing,6000,9500,13000,202,6000,603.123.6666,1997-08-17T00:00:00.000-06:00,"Pat Fay",PFAY,2Useful?

• Access Control Service: Transitioning between Active and Passive Scenarios

  - by Your DisplayName here!

  As I mentioned in my last post, ACS features a number of ways to transition between protocol and token types. One not so widely known transition is between passive sign ins (browser) and active service consumers. Let’s see how this works. We all know the usual WS-Federation handshake via passive redirect. But ACS also allows driving the sign in process yourself via specially crafted WS-Federation query strings. So you can use the following URL to sign in using LiveID via ACS. ACS will then redirect back to the registered reply URL in your application: GET /login.srf?   wa=wsignin1.0&   wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&   wreply=https%3a%2f%2fleastprivilege.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&   wp=MBI_FED_SSL&   wctx=pr%3dwsfederation%26rm%3dhttps%253a%252f%252froadie%252facs2rp%252frest%252f The wsfederation bit in the wctx parameter indicates, that the response to the token request will be transmitted back to the relying party via a POST. So far so good – but how can an active client receive that token now? ACS knows an alternative way to send the token request response. Instead of doing the redirect back to the RP, it emits a page that in turn echoes the token response using JavaScript’s window.external.notify. The URL would look like this: GET /login.srf?   wa=wsignin1.0&   wtrealm=https%3a%2f%2faccesscontrol.windows.net%2f&   wreply=https%3a%2f%2fleastprivilege.accesscontrol.windows.net%3a443%2fv2%2fwsfederation&   wp=MBI_FED_SSL&   wctx=pr%3djavascriptnotify%26rm%3dhttps%253a%252f%252froadie%252facs2rp%252frest%252f ACS would then render a page that contains the following script block: <script type="text/javascript">     try{         window.external.Notify('token_response');     }     catch(err){         alert("Error ACS50021: windows.external.Notify is not registered.");     } </script> Whereas token_response is a JSON encoded string with the following format: {   "appliesTo":"...",   "context":null,   "created":123,   "expires":123,   "securityToken":"...",   "tokenType":"..." } OK – so how does this all come together now? As an active client (Silverlight, WPF, WP7, WinForms etc). application, you would host a browser control and use the above URL to trigger the right series of redirects. All the browser controls support one way or the other to register a callback whenever the window.external.notify function is called. This way you get the JSON string from ACS back into the hosting application – and voila you have the security token. When you selected the SWT token format in ACS – you can use that token e.g. for REST services. When you have selected SAML, you can use the token e.g. for SOAP services. In the next post I will show how to retrieve these URLs from ACS and a practical example using WPF.

• AppEngine JRuby - OutOfMemoryError: Java heap space - can it be solved?

  - by elado

  I use AppEngine JRuby on Rails (SDK version 1.3.3.1) - a problem I encounter often is that after a few requests the server is getting really SLOW, until it dies and throws OutOfMemoryError on the terminal (OSX). The requests themselves are very lightweight, not more than looking for an entity or saving it, using DataMapper. On appspot, this problem is not happening. Is there any way to enlarge the heap space for JRuby? The exception log: Exception in thread "Timer-2" java.lang.OutOfMemoryError: Java heap space Apr 29, 2010 8:08:22 AM com.google.apphosting.utils.jetty.JettyLogger warn WARNING: Error for /users/close_users java.lang.OutOfMemoryError: Java heap space at org.jruby.RubyHash.internalPut(RubyHash.java:480) at org.jruby.RubyHash.internalPut(RubyHash.java:461) at org.jruby.RubyHash.fastASet(RubyHash.java:837) at org.jruby.RubyArray.makeHash(RubyArray.java:2998) at org.jruby.RubyArray.makeHash(RubyArray.java:2992) at org.jruby.RubyArray.op_diff(RubyArray.java:3103) at org.jruby.RubyArray$i_method_1_0$RUBYINVOKER$op_diff.call(org/jruby/RubyArray$i_method_1_0$RUBYINVOKER$op_diff.gen) at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:146) at org.jruby.ast.CallOneArgNode.interpret(CallOneArgNode.java:57) at org.jruby.ast.LocalAsgnNode.interpret(LocalAsgnNode.java:123) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.runtime.InterpretedBlock.evalBlockBody(InterpretedBlock.java:373) at org.jruby.runtime.InterpretedBlock.yield(InterpretedBlock.java:346) at org.jruby.runtime.InterpretedBlock.yield(InterpretedBlock.java:303) at org.jruby.runtime.Block.yield(Block.java:194) at org.jruby.RubyArray.collect(RubyArray.java:2354) at org.jruby.RubyArray$i_method_0_0$RUBYFRAMEDINVOKER$collect.call(org/jruby/RubyArray$i_method_0_0$RUBYFRAMEDINVOKER$collect.gen) at org.jruby.runtime.callsite.CachingCallSite.callBlock(CachingCallSite.java:115) at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:122) at org.jruby.ast.CallNoArgBlockNode.interpret(CallNoArgBlockNode.java:64) at org.jruby.ast.CallNoArgNode.interpret(CallNoArgNode.java:61) at org.jruby.ast.LocalAsgnNode.interpret(LocalAsgnNode.java:123) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.ast.EnsureNode.interpret(EnsureNode.java:98) at org.jruby.ast.BeginNode.interpret(BeginNode.java:83) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.ast.EnsureNode.interpret(EnsureNode.java:96) at org.jruby.internal.runtime.methods.InterpretedMethod.call(InterpretedMethod.java:201) at org.jruby.internal.runtime.methods.DefaultMethod.call(DefaultMethod.java:183)

• Problem with Informix JDBC, MONEY and decimal separator in string literals

  - by Michal Niklas

  I have problem with JDBC application that uses MONEY data type. When I insert into MONEY column: insert into _money_test (amt) values ('123.45') I got exception: Character to numeric conversion error The same SQL works from native Windows application using ODBC driver. I live in Poland and have Polish locale and in my country comma separates decimal part of number, so I tried: insert into _money_test (amt) values ('123,45') And it worked. I checked that in PreparedStatement I must use dot separator: 123.45. And of course I can use: insert into _money_test (amt) values (123.45) But some code is "general", it imports data from csv file and it was safe to put number into string literal. How to force JDBC to use DBMONEY (or simply dot) in literals? My workstation is WinXP. I have ODBC and JDBC Informix client in version 3.50 TC5/JC5. I have set DBMONEY to just dot: DBMONEY=. EDIT: Test code in Jython: import sys import traceback from java.sql import DriverManager from java.lang import Class Class.forName("com.informix.jdbc.IfxDriver") QUERY = "insert into _money_test (amt) values ('123.45')" def test_money(driver, db_url, usr, passwd): try: print("\n\n%s\n--------------" % (driver)) db = DriverManager.getConnection(db_url, usr, passwd) c = db.createStatement() c.execute("delete from _money_test") c.execute(QUERY) rs = c.executeQuery("select amt from _money_test") while (rs.next()): print('[%s]' % (rs.getString(1))) rs.close() c.close() db.close() except: print("there were errors!") s = traceback.format_exc() sys.stderr.write("%s\n" % (s)) print(QUERY) test_money("com.informix.jdbc.IfxDriver", 'jdbc:informix-sqli://169.0.1.225:9088/test:informixserver=ol_225;DB_LOCALE=pl_PL.CP1250;CLIENT_LOCALE=pl_PL.CP1250;charSet=CP1250', 'informix', 'passwd') test_money("sun.jdbc.odbc.JdbcOdbcDriver", 'jdbc:odbc:test', 'informix', 'passwd') Results when I run money literal with dot and comma: C:\db_examples>jython ifx_jdbc_money.py insert into _money_test (amt) values ('123,45') com.informix.jdbc.IfxDriver -------------- [123.45] sun.jdbc.odbc.JdbcOdbcDriver -------------- there were errors!

• Seperating Javascript and Html, when dynamically adding html via javascript

  - by optician

  I am currently building a very dynamic table for a list application, which will basically perform basic CRUD functions via AJAX. What I would like to do is separate the visual design and javascript to the point where I can change the design side without touching the JS side. This would only work where the design stays roughly the same(i would like to use it for rapid protyping) Here is an example. <table> <tr><td>record-123</td><td>I am line 123</td><td>delete row</td></tr> <tr><td>record-124</td><td>I am line 124</td><td>delete row</td></tr> <tr><td>record-125</td><td>I am line 125</td><td>delete row</td></tr> <tr><td>add new record</td></tr> </table> Now, when I add a new record, I would like to insert a new row of html, but I would rather not put this html into the javascript file. What I am considering is creating a row like this on the page, near the table. <tr style='visble:none;' id='template-row'><td>record-id</td><td>content-area</td><td>delete row</td></tr> And when I come to add the new row, I search the page for the tags with the id=template-row , and then grab it, do a string replace on it, and then put it in the right place in the page. As long as the design doesn't shift radically, and I keep the placeholder strings the same, it means designs can be quickly modified without touching the js. Can any give any advice on a methodology like this?

• Copy Selective Data from Database to Invoice, Based on Certain Criteria

  - by Scott

  For starters, here is an example of a microsoft excel database I am working with: Month/Address/Name/Description/Amount January/123 Street/Fred/Painting/100 January/456 Avenue/Scott/Flooring/400 January/789 Road/Scott/Plumbing/100 February/123 Street/Fred/Flooring/600 February/246 Lane/Fred/Electrical/300 March/789 Road/Scott/Drywall/150 What I want to be able to do is selectively copy info from this databse to invoices (also excel). The invoice has three columns: Address/Description/Amount. I want to be able to automatically fill the invoices in as the database is filled in (either automatically, or if I have to actually manually run the macro to do it, that might be fine). Each name (Scott, Fred, etc.) will have their own set of 12 invoices for the year. So, e.g., I want to be able to produce a January invoice for all work done for Scott in January, showing the address, the description and the amount, line by line. So every time work on Scott's address(es) is done, the database is filled in, and i want it to "send" that information to the invoice on the next available line, filling in only the Address/Description/Amount columns from the database. Fred's invoice should fill in as any work is done on Fred's addresses. And once the month changes, the next invoice should start filling in. So first I need to filter the data by the month and the name (and there is actually one more column to filter by, but let's keep this example simpler). Then I need to list the remaining data on the invoice, but only certain cells from the rows that are now left. Help anyone?

• Linking errors when building against Boost Unit Test Framework

  - by Rafid

  I am trying to use Boost Unit Test Framework by building a stand alone library as detailed here: http://www.boost.org/doc/libs/1_35_0/libs/test/doc/components/utf/compilation.html So I created a VC library project containing the mentioned files and build it and it was successful.

• PDF parsing file trailer

  - by Ralph

  It is not clear from the PDF ISO standard document (PDF32000-2008) whether a comment may follow the startxref keyword: startxref Byte_offset_of_last_cross-reference_section %%EOF The standard does seem to imply that comments may appear anywhere: 7.2.3 Comments Any occurrence of the PERCENT SIGN (25h) outside a string or stream introduces a comment. The comment consists of all characters after the PERCENT SIGN and up to but not including the end of the line, including regular, delimiter, SPACE (20h), and HORZONTAL TAB characters (09h). A conforming reader shall ignore comments, and treat them as single white-space characters. That is, a comment separates the token preceding it from the one following it. EXAMPLE The PDF fragment in this example is syntactically equivalent to just the tokens abc and 123. abc% comment ( /%) blah blah blah 123 Comments (other than the %PDF–n.m and %%EOF comments described in 7.5, "File Structure") have no semantics. They are not necessarily preserved by applications that edit PDF files. If they are allowed to appear after the startxref, parsing the file becomes more difficult because you do not know how far to back up from the %%EOF comment to start parsing to find the byte offset. Any ideas?

• Database design for sharing photos site?

  - by javaLearner.java

  I am using php and mysql. If I want to do a sharing photos website, whats the best database design for upload and display photos. This is what I have in mind: domain: |_> photos |_> user Logged in user will upload photo in [http://www.domain.com/user/upload.php] The photos are stored in filesystems, and the path-to-photos stored in database. So, in my photos folder would be like: photos/userA/subfolders+photos, photos/userB/subfolders+photos, photos/userC/subfolders+photos etc Public/others people may view his photo in: [http://www.domain.com/photos/user/?photoid=123] where 123 is the photoid, from there, I will query from database to fetch the path and display the image. My questions: Whats the best database design for photo-sharing website (like flickr)? Will there be any problems if I keep creating new folder in "photos" folder. What if hundreds of thousands users registered? Whats the best practices What size of photos should I keep? Currently I only stored thumbnail (100x100) and (max) 1600x1200 px photos. What others things I should take note when developing photos-sharing website?
