• Using ADO.NET Entities LINQ Provider to model complex SQL Queries?

  - by Ivan Zlatanov

  What I find really powerful in ADO.NET Entities or LINQ to SQL, is the ability to model complex queries. I really don't need the mappings that Entities or LINQ to SQL are doing for me - I just need the ability to model complex expressions that can be translated into T-SQL. My question is - am I abusing too much? Can I use the Entity Framework for modeling queries and just that? Should I? I know I can write my own custom LINQ to SQL provider, but that is just not possible to handle in the time spans I have. What is the best approach to model complex T-SQL queries? How do you handle conditional group byes, orders, joins, unions etc in the OOP world? Using StringBuilders for this kind of job feels too ugly and harder to maintain given the possibilities we have with Expression Trees. When I use StringBuilder to model a complex SQL Query I feel kind of guilty! I feel the same way as when I have to hard code any number into my code that is different than 0 or 1. Feeling that makes you ask yourself if there is a better and cleaner way of doing it... I must mention that I am using C# 4.0, but I am not specifically looking for an answer in this language, but rather in the domain of CLR 4.

• Can this extension method be improved?

  - by Newbie

  I have the following extension method public static class ListExtensions { public static IEnumerable<T> Search<T>(this ICollection<T> collection, string stringToSearch) { foreach (T t in collection) { Type k = t.GetType(); PropertyInfo pi = k.GetProperty("Name"); if (pi.GetValue(t, null).Equals(stringToSearch)) { yield return t; } } } } What it does is by using reflection, it finds the name property and then filteres the record from the collection based on the matching string. This method is being called as List<FactorClass> listFC = new List<FactorClass>(); listFC.Add(new FactorClass { Name = "BKP", FactorValue="Book to price",IsGlobal =false }); listFC.Add(new FactorClass { Name = "YLD", FactorValue = "Dividend yield", IsGlobal = false }); listFC.Add(new FactorClass { Name = "EPM", FactorValue = "emp", IsGlobal = false }); listFC.Add(new FactorClass { Name = "SE", FactorValue = "something else", IsGlobal = false }); List<FactorClass> listFC1 = listFC.Search("BKP").ToList(); It is working fine. But a closer look into the extension method will reveal that Type k = t.GetType(); PropertyInfo pi = k.GetProperty("Name"); is actually inside a foreach loop which is actually not needed. I think we can take it outside the loop. But how? PLease help. (C#3.0)

• Matlab matrix translation and rotation multiple times

  - by pinnacler

  I have a map of individual trees from a forest stored as x,y points in a matrix. I call it fixedPositions. It's cartesian and (0,0) is the origin. I would like 0/360 degrees to be the top of the screen and 90 degrees to be to the right. Given a velocity and a heading, i.e. .5 m/s and 60 degrees (2 o'clock equivalent on a watch), how do I rotate that x,y points, so that the new origin is centered at (.5cos(60),.5sin(60)) and 60 degrees is now at the top of the screen? Then if I were to give you another heading and speed, i.e. 0 degrees and 2m/s, it should calculate it from the last point, not the original fixedPositions origin. I've wasted my day trying to figure this out. I wish I took matrix algebra but I'm at a loss. I tried doing cos(30) and even those wouldn't compute correctly, which after an hour I realize were in radians.

• Git can no longer open emacs as its editor

  - by mwilliams

  I'm running Git version 1.7.3.2 that I built from source, zsh is my shell, and emacs is my editor. Recently I started seeing the following: /usr/local/Cellar/git/1.7.3.2/libexec/git-core/git-sh-setup: line 106: emacs: command not found Could not execute editor My zshrc looks like the following so I can use the Cocoa build and the console binary provided with it. EMACS_HOME="/Applications/Emacs.app/Contents/MacOS" function e() { PATH=$EMACS_HOME/bin:$PATH $EMACS_HOME/Emacs -nw $@ } function ec() { PATH=$EMACS_HOME/bin:$PATH emacsclient -t $@ } function es() { e --daemon=$1 && ec -s $1 } function el() { ps ax|grep Emacs } function ek() { $EMACS_HOME/bin/emacsclient -e '(kill-emacs)' -s $1 } function ecompile() { e -eval "(setq load-path (cons (expand-file-name \".\") load-path))" \ -batch -f batch-byte-compile $@ } alias emacs=e alias emacsclient=ec And I also have export EDITOR="emacs" and have tried adding export GIT_EDITOR="emacs" (and swapping that out with "e") But whatever I try I can't get git to open emacs whenever I need to do a commit or an interactive rebase, etc etc...

• JMeter CSV Data Set is corrupting Japanese strings stored as proper UTF-8, I get Question Marks instead

  - by Mark Bennett

  I read in search terms from a simple text file to send to a search engine. It works fine in English, but gives me ???? for any Japanese text. Text with mixed English and Japanese does show the English text, so I know it's reading it. What I'm seeing: Input text: Snow Leopard ??????????????? Turns into: Snow Leopard ??????????????? This is in my POST field of an HTTP. If I set JMeter to encode the data, it just puts in the percent sequence for question marks. Interesting note: In the example above there are 15 Japanese characters, and then 15 question marks, so at some point it's being seen as full characters and not just bytes. About the Data: The CSV file is very simple in structure. There's only one field / one column, which I name TERM, and later use as ${TERM} I don't really need full CSV because it's only one string per line. There's no commas or quotes. When I run the Unix "file" command on the file, it says UTF-8 text. I've also verified it in command line and graphical mode on two machines. JMeter CSV Dataset Config: Filename: japanese-searches.csv File encoding: UTF-8 (also tried without) Variable names: TERM Delimiter: , Allow Quoted Data: False (I also tried True, different, but still wrong) Recycle at EOF: True Stop at EOF: False Staring mode: All threads A few things I've tried: Tried Allow quoted Data. It changed to other strange characters. -Dfile.encoding=UTF-8 Tried encoding the POST, but it just turned into a bunch of %nn for question marks And I'm not sure how "debug" just after the each line of the CSV is read in. I think it's corrupted right away, but I'm not sure. If it's only mangled when I reference it, then instead of ${TERM} perhaps there's some other "to bytes" function call. I'll start checking into that. I haven't done anything with the JMeter functions yet.

• IE7: container of hidden Div displays incorrectly

  - by dmr

  There is a search box div that contains a boxhead div and a boxbody div. Inside the boxbody div, there is a searchToggle div. When the user clicks a certain link on the page, the display style property of the searchToggle div is toggled between block and none. The 2 background-images for the body of the search box are set via the css of the searchBox div and the boxbody div. In IE7, when the searchToggle div is hidden, the background-image from the searchBox div extends on the left more than it should. It shows up correctly when the display of the searchToggle div is block. Everything show up correctly, in both cases in IE8 and FF. Any ideas why this is happening? The relevant HTML: <div class="searchBox"> <div class="boxhead"> <h2></h2> </div> <div class="boxbody"> <div id="searchToggle" name="searchToggle"> </div> </div> </div> The relevant CSS: .searchBox { margin: 0 auto; width: 700px; background: url(/images/myImageRight-r.gif) no-repeat bottom right; font-size: 100%; text-align: left; overflow: hidden; } .boxbody { margin: 0; padding: 5px 30px 31px; background-image: url(/images/myImageLeft.gif); background-repeat: no-repeat; background-position: left bottom; }

• What could possibly be different between the table in a DataContext and an IQueryable<Table> when do

  - by Nate Bross

  I have a table, where I need to do a case insensitive search on a text field. If I run this query in LinqPad directly on my database, it works as expected Table.Where(tbl => tbl.Title.Contains("StringWithAnyCase") In my application, I've got a repository which exposes IQueryable objects which does some initial filtering and it looks like this var dc = new MyDataContext(); public IQueryable<Table> GetAllTables() { var ret = dc.Tables.Where(t => t.IsActive == true); return ret; } In the controller (its an MVC app) I use code like this in an attempt to mimic the LinqPad query: var rpo = new RepositoryOfTable(); var tables = rpo.GetAllTables(); // for some reason, this does a CASE SENSITIVE search which is NOT what I want. tables = tables.Where(tbl => tbl.Title.Contains("StringWithAnyCase"); return View(tables); The column is defiend as an nvarchar(50) in SQL Server 2008. Any help or guidance is greatly appreciated!

• jQuery pagination without all the rows of data before hand

  - by Aaron Mc Adam

  Hi guys, I'm trying to find a solution for paginating my search results. I have a built the links and everything works without jQuery. I've also got AJAX working for the links, but I just need a way of tidying up the list of links, as some search results return up to 60 pages and the links spread to two rows in my template. I am searching the Amazon API, and can only return 10 results at a time. Upon clicking the pagination links, the next 10 results are returned. I have access to the total results number from the XML, but not all the data at once, so I can't put all the data into a "hiddenResults" div that the jQuery Pagination plugin needs. Here is the jQuery I have for the pagination: var $pagination = $("#pagination ul"); $pagination.delegate('.pagenumbers', 'click', function() { var $$this = $(this); $$this.closest('li').addClass('cached'); $pagination.find("#currentPage").removeAttr('id').wrapInner($('<a>', {'class':'pagenumbers', 'href':'book_data.php?keywords='+keywords})); $$this.closest('li').attr('id','currentPage').html( $$this.text() ); $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : $$this.text() }, success : show_results }); return false; }); function show_results(res) { $("#searchResults").replaceWith($(res).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); if ( ! ( $pagination.find('li').hasClass('cached') ) ) { $.get("book_data.php", { keywords : keywords, page : ( $pagination.find("#currentPage").text() + 1 ) } ); } }

• How useful is mounting /tmp noexec?

  - by Novelocrat

  Many people (including the Securing Debian Manual) recommend mounting /tmp with the noexec,nodev,nosuid set of options. This is generally presented as one element of a 'defense-in-depth' strategy, by preventing the escalation of an attack that lets someone write a file, or an attack by a user with a legitimate account but no other writable space. Over time, however, I've encountered arguments (most prominently by Debian/Ubuntu Developer Colin Watson) that noexec is a useless measure, for a couple potential reasons: The user can run /lib/ld-linux.so <binary> in an attempt to get the same effect. The user can still run system-provided interpreters on scripts that can't be run directly Given these arguments, the potential need for more configuration (e.g. debconf likes an executable temporary directory), and the potential loss of convenience, is this a worthwhile security measure? What other holes do you know of that enable circumvention?

• Eclipse: Organising Files

  - by someguy

  I want to import a project that I'm planning to build upon. The problem is that it is very messy; with source files, class files and libraries under one directory. How would I organise these files using Eclipse? I know you can change the source folder and output folder, but when I do change the source folder, the files that I want inside it do not physically move to that folder. Output folder is fine, though. Also, I would like a separate folder for libraries. I'm not sure how I would go about this, however. Here's how I would like it: src: This folder will contain source files. bin: This folder will contain binary (class) files. lib: This folder will contain external libraries.

• recover deleted files from other computer

  - by Giorgi

  Hello, I moved a html file from my computer to another and accidentally deleted it from that computer which I accessed from my computer like this: \name\folder As a result the file did not go recycle bin. I tried ntfsundelete and it did found the file on my computer but when I recovered, it looks like as if you opened binary file with notepad. I then tried Recuva and it says that part of the file is overwritten. Is there any chance to recover it? Can I recover it from another computer? Thanks.

• How can a wix custom action dll call be made to use the debug runtime via a merge module?

• What postgresql client version should I build against, if server is 8.x?

  - by Ben Voigt

  I'm planning updates to a system that is currently running with 8.x server on Windows, 8.x client on Windows, and 8.x client on Linux. Obviously that seems like a bad choice of platform in a mixed environment, but the Linux machine has no persistent writable storage (as an anti-rootkit measure). I'm concerned with compatibility between versions right now. Can a linux postgresql 9.0.x client connect to a Windows 8.x server? The server is using some third-party binary extensions, so upgrading it is a more involved task and will be done later. If combining a 9.0.x client and 8.x server is discouraged, would latest 8.x clients be able to continue to connect if I did upgrade the server first? META: What tag is appropriate for backward-compatibility questions?

• Setting subversion "password-stores" does nothing?

  - by Coderer

  The Subversion documentation says that I can set a parameter in ~/.subversion/config like [auths] password-stores = gnome-keyring to have it cache my certificate password in gnome-keyring. I set the option, and nothing happens -- no error messages, no change in behavior, nothing. Maybe I'm missing a log somewhere? I know subversion has to be compiled to support this but AFAIK I'm using the RPM version, which (they say...) ships with it rolled in. Is there a way to check whether my binary supports keyring? Shouldn't it say something if it doesn't?

• Homebrew build with different arch?

  - by StasM

  I tried to install mysql-connector-c recipe via homebrew, and it builds just fine, but produces x86_64 library: $file ~/brew/lib/libmysql.dylib .../brew/lib/libmysql.dylib: Mach-O 64-bit dynamically linked shared library x86_64 I however need i386 library for my project. I tried to give it CFLAGS and LDFLAGS like this: CFLAGS="-arch i386 -arch x86_64" LDFLAGS="-arch i386 -arch x86_64" brew install mysql-connector-c but nothing changes - it still builds x86_64 only binary. Is there any way to make homebrew build either dual arch library or i386 library? I have kernel architecture set to x86_64, if it matters.

• How to pin NetBeans to Windows 7 taskbar?

  - by Vilx-

  I've googled around and it seems that I'm not the only one with the problem, however I couldn't find the solution. Maybe someone around here has figured it out. The problem is that netbeans.exe is actually a stub which is calling javaw.exe. When I try to pin the NetBeans process to the taskbar I actually pin "Java(TM) Platform SE Binary". That changes the icon and the pin doesn't work. The funny thing is that it works on another machine. I don't know whether it's because it's a different version of NetBeans, or a different version of Java. Has anyone figured this out? Added: I know this is sort of not programming related; on the other hand there are plenty of topics around here about how to better your programming environment, and this one is no worse than those. Oh, and btw - Windows 7 Enterprise x64; Java JDK 1.6.17; Netbeans 6.8

• Projects integration question

  - by qkrsppopcmpt

  Other team has one legacy system, which is data aggregators. It is implemented as web service using JAVA, SOAP,MTOM,Tomcat and Axis2. They have wsdl files defining functionalities such as search, retrieve data, upload, download. Our team has a new developed website which is developed using RoR with mySQL. It is sort of social networking. Users can register, add friends, upload images, videos. Also, they can search data. We are required to connect the two systems. One possible solution I think is - Adding components into our website. The component invoke services on the aggregators. - Synchronize website database to the aggregators. My doubts are: 1. How to add components in our websites? The components should use Java or Ruby or adapter from java to ruby. It is possible using ruby invoke web service. I think it should work since it is the point of web service. If so, can ruby call those services in wsdl directly? But how to deal with those different data structure? How to synchroinze our database to the aggregators. I think the best way is also through web service invocation such as upload. That means, we have to export the db records into xml files and then write some tools to upload. The web service project support MTOM. So, it is fine to upload huge data. Am I on the right record? Can anybody give me some hint. Thanks.

• Subscribe to feed in Thunderbird from the command line?

  - by Coderer

  From reading around the web, it looks like Firefox's "quick view" of an RSS feed sometimes lets you "Subscribe to this feed using" Thunderbird. For whatever reason, that's not an automatically-added option with my setup (FF 3.5.something + Thunderbird 3.0.something on Linux), so I figured I could just "Choose Application...", point at the Thunderbird binary, and be on my way. Not so -- nothing appears to happen. If I run thunderbird from the command line as thunderbird "http://path/to/feed" the app launches as normal. If it's already running, absolutely nothing happens. Is this impossible? Is there some mojo I can pass Firefox to tell it that Thunderbird exists? Should I just suck it up and copy/paste the URLs manually?

• How do I detect proximity of the mouse pointer to a line in Flex?

  - by Hanno Fietz

  I'm working on a charting UI in Flex. One of the features I want to implement is "snapping" of the mousepointer to the data points in the diagram. I. e., if the user hovers the mouse pointer over a line diagram and gets close to the data point, I want the pointer to move to the exact coordinates and show a marker, like this: Currently, the lines are drawn on a Shape, using the Graphics API. The Shape is a child DisplayObject of a custom UIComponent subclass with the exact same dimensions. This means, I already get mouseOver events on the parent of the diagram's canvas. Now I need a way to detect if the pointer is close to one of the data points. I. e. I need an answer to the question "Which data points lie within a radius of x pixels from my current position and which of them is closest?" upon each move of the mouse. I can think of the following possibilities: draw the lines not as simple lines in the graphics API, but as more advanced objects that can have their own mouseOver events. However, I want the snapping to trigger before the mouse is actually over the line. check the original data for possible candidates upon each mouse movement. Using binary search, I might be able to reduce the number of items I have to compare sufficently. prepare some kind of new data structure from the raw data that makes the above search more efficient. I don't know how that would look like. I'm guessing this is a pretty standard problem for a number of applications, but probably the actual code usually is inside of some framework. Is there anything I can read about this topic?

• Are there ways to write php/python code to run as hooks in the Apache Request Processing pipeline?

  - by SB

  Does anybody know of any modules that provide the functionality to write python or PHP code to run as hooks in the Apache request processing pipeline? For instance, mod_perl lets me write PerlModules, which can contain handlers for the header parsing phase, content delivery, and even filters. I would like to do something similar in other scripting languages. I could write it in C, but the goal is to deploy a module that would work across a number of systems. If I deliver it as binary in C, then it would require 64/32-bit versions and some other issues. With perl, I can just require certain modules installed and mod_perl2.

• Copy recordset data into multiple sheets to avoid problem of maximum rows limit in Excel VBA

  - by Sam

  I am developing reporting application in Excel/vba 2003. VBA code sends search query to database and gets the data through recordset. It will then be copied to one of excel sheet. The rertrieved data looks like as shown below. ProductID--|---DateProcessed--|----State----- 1................|.. 1/1/2010..............|.....Picked Up 1................|.. 1/1/2010..............|.....Forward To Approver 1................|.. 1/2/2010..............|.....Approver Picked Up 1................|.. 1/3/2010..............|.....Approval Completed 2................|.. 1/1/2010..............|.....Picked Up 3................|.. 1/2/2010..............|.....Picked Up 3................|.. 1/2/2010..............|.....Forward To Approver The problem is data retrieved from search query is so huge that it goes above the excel row limit (65536 rows in excel 2003). So I want to split this data into two excel sheets. While spliting the data I want to ensure that the data for same product shoud remain in one sheet. For example, if the last record in the above result set is 65537th record then I also want to move all records for product 3 into new sheet. So sheet1 will contain records for product id 1 and 2 with total records = 65534. Sheet 2 will cotain records for product id 3 - with total records = 2. How can I acheive this in vba? If it is not possible, is there any alternative solution ? Thanks in Advance !

• Why can't RB-Tree be a list?

  - by Alex

  Hey everyone. I have a problem with the rb-trees. according to wikipedia, rb-tree needs to follow the following: A node is either red or black. The root is black. (This rule is used in some definitions and not others. Since the root can always be changed from red to black but not necessarily vice-versa this rule has little effect on analysis.) All leaves are black. Both children of every red node are black. Every simple path from a given node to any of its descendant leaves contains the same number of black nodes. As we know, an rb-tree needs to be balanced and has the height of O(log(n)). But, if we insert an increasing series of numbers (1,2,3,4,5...) and theoretically we will get a tree that will look like a list and will have the height of O(n) with all its nodes black, which doesn't contradict the rb-tree properties mentioned above.

• I need a few minutes of dedicated server a week, but not for hosting, just to convert ogg etc

  - by talkingnews

  I'm completely happy with my webhosting, it's just that I need to do one little thing they won't allow, and that's run an instance of Sox to convert about 30 mp3s to ogg files, in various directories, a couple of times a week, to be done automatically in response to the detection of the upload of an mp3. Probably looking at a minute of server time over the whole week. I've had unhelpful suggestions on other forums like "why not leave your home PC on 24 hours a day and then use all your isp bandwidth to do this", which doesn't work for me. I know that I can host files on, say, Amazon S3, but is there something similar for my needs? All it would need to do would be: wget/ftp the mp3 files, convert them to ogg, ftp the files back to my hosting. Of course, all this wouldn't be needed if there was such a thing as a compiled binary of Sox (or any mp3ogg converter) for Centos which I could upload without needing root access, but I've given up asking that one, but always open to suggestions!
