• An algo for generating code callgraphs

  - by Shrey

  I am working on a project which requires generating some metrices of a code (it can be C/C++/Java/Python). One of the metrices can be that I create a callgraph after parsing the code entered (the programs are expected to be small - probably under 1000L). As of now, I am looking for a way to create a program (it can be C/Python) which can take as input a file (C/C++/Python/Java) and then create a textual output containing approximate calling sequence as well as tokens in the code file. As of now, I have looked at some other tools which do the same thing - like splint, pylint, codeviz etc. So, I have two ways of solving my problem: Read and understand the algorithm these tools use (tokenization-graph generation etc) Or, have a basic algo (something like very high level steps) and then sit down to create each of them as I want them to be. I know, re-inventing the wheel is not a good idea, but, I would still like to give option (2) a shot. Only issue is, currently I am a blank. My question: Does any one have any knowhow about how to create code graphs? Any hints as to what I should do? Any top levels steps which I can follow? Thanks a lot.

• Sanitize input before executing at server in php

  - by Interfaith

  I want to let user input two variable, Name and Password in a form. I want to disable any XSS or script insert in the input values. I have the following code in the form method: <form name="form1" method="post" action="checkpw.php"> Your Name: <table> <tr><td><input class="text" name="name" onBlur="capitalize(this);" maxlength=12 type="text" /></td></tr> </table> Password: <table> <tr><td><input class="text" name="passwd" maxlength=8 type="password" /></td></tr> <tr><td align="center"><br/> <input class="text" type="submit" name="submitbt" value="Login" /> </td></tr> </table> and the following checkpw.php: <?php // Clean up the input values $post = filter_input_array(INPUT_POST, array( 'name' => FILTER_SANITIZE_STRING, 'pw' => FILTER_SANITIZE_STRING, )); if (is_null($post) || in_array(null, $post)) { header("location:login.php"); return; // missing fields (or failed filter) } // pw is the password sent from the form $pw=$_POST['passwd']; $name=$_POST['name']; if($pw == 'testpass'){ header("location:index.php"); } else { header("location:wrong.php"); } ?> Is this a secure way to ensure the form is sent to the server and executed ONLY after the input values have been sanitized? Also, the $name value i want to pass it to index.php file. I insert a code in the index.php as follow: <?php echo $name ?> But it's empty. Any idea how to resolve it?

• Getting Response From Jquery JSON

  - by Howdy_McGee

  I'm having trouble getting a response from my php jquery / json / ajax. I keep combining all these different tutorials together but I still can't seem to pull it all together since no one tutorial follow what I'm trying to do. Right now I'm trying to pass two arrays (since there's no easy way to pass associative arrays) to my jquery ajax function and just alert it out. Here's my code: PHP $names = array('john doe', 'jane doe'); $ids = array('123', '223'); $data['names'] = $names; $data['ids'] = $ids; echo json_encode($data); Jquery function getList(){ $.ajax({ type: "GET", url: 'test.php', data: "", complete: function(data){ var test = jQuery.parseJSON(data); alert(test.names[0]); alert("here"); } }, "json"); } getList(); In my html file all I'm really calling is my javascript file for debugging purposes. I know i'm returning an object but I'm getting an error with null values in my names section, and i'm not sure why. What am I missing? My PHP file returns {"names":["john doe","jane doe"],"ids":["123","223"]} It seems to be just ending here Uncaught TypeError: Cannot read property '0' of undefined so my sub0 is killing me.

• iBatis how to solve a more complex N+1 problem

  - by Alvin

  I have a database that is similar to the following: create table Store(storeId) create table Staff(storeId_fk, staff_id, staffName) create table Item(storeId_fk, itme_id, itemName) The Store table is large. And I have create the following java bean public class Store { List<Staff> myStaff List<Item> myItem .... } public class Staff { ... } public class Item { ... } My question is how can I use iBatis's result map to EFFICIENTLY map from the tables to the java object? I tried: <resultMap id="storemap" class="my.example.Store"> <result property="myStaff" resultMap="staffMap"/> <result property="myItem" result="itemMap"/> </resultMap> (other maps omitted) But it's way too slow since the Store table is VERY VERY large. I tried to follow the example in Clinton's developer guide for the N+1 solution, but I cannot warp my mind around how to use the "groupBy" for an object with 2 list... Any help is appreciated!

• Why does Firefox + My code Destroys FireFox refresh

  - by acidzombie24

  I am soo angry right now. I lost hours and i dont know why this happens. Its a semi rant but i'll try to keep it short My code would not work, even after refreshing it was broken I fixed my code or so i thought because it stops working without me changing anything (you would think i am imagining this...) I somehow decide to make a new window or tab i run my code and verifies it works. I write more code and see everything is broken again I write test in a new window and see my code does work I see my code doesnt work and firebug DOES NOT HELP I notice when i create a new tab everything works I realize refreshing does not work and i MUST make a new tab for my code to work. Then i knew instantly what the problem was. I modify a display:none textbox but i set the values incorrectly. I cant see it because it is hidden. Now some of you might say its my fault because when doing a refresh all of the data may be cache. But here is the kicker. I was using POST data. I posted in between of the refresh each and everytime. Whats the point of using POST when the same data is cached and use anyways? If theres no chance for a search engine to follow a block user get link then why should i bother making anything post when security or repeat actions are not an issue? POST didnt seem to do anything.

• Weird compile-time behavior when trying to use primitive type in generics

  - by polygenelubricants

  import java.lang.reflect.Array; public class PrimitiveArrayGeneric { static <T> T[] genericArrayNewInstance(Class<T> componentType) { return (T[]) Array.newInstance(componentType, 0); } public static void main(String args[]) { int[] intArray; Integer[] integerArray; intArray = (int[]) Array.newInstance(int.class, 0); // Okay! integerArray = genericArrayNewInstance(Integer.class); // Okay! intArray = genericArrayNewInstance(int.class); // Compile time error: // cannot convert from Integer[] to int[] integerArray = genericArrayNewInstance(int.class); // Run time error: // ClassCastException: [I cannot be cast to [Ljava.lang.Object; } } I'm trying to fully understand how generics works in Java. Things get a bit weird for me in the 3rd assignment in the above snippet: the compiler is complaining that Integer[] cannot be converted to int[]. The statement is 100% true, of course, but I'm wondering WHY the compiler is making this complaint. If you comment that line, and follow the compiler's "suggestion" as in the 4th assignment, the compiler is actually satisfied!!! NOW the code compiles just fine! Which is crazy, of course, since like the run time behavior suggests, int[] cannot be converted to Object[] (which is what T[] is type-erased into at run time). So my question is: why is the compiler "suggesting" that I assign to Integer[] instead for the 3rd assignment? How does the compiler reason to arrive to that (erroneous!) conclusion?

• Is there a recommended way to communicate scientific/engineering programming to C developers?

  - by ggkmath

  Hi, I have a lot of MATLAB code that needs to get ported to C (execution speed is critical for this work) as part of a back-end process for a web application. When I attempt to outsource this code to a C developer, I assume (correct me if I'm wrong) few C developers also understand MATLAB code (things like indexing and memory management are different, etc.). I wonder if there are any C developers out there that can recommend a procedure for me to follow to best communicate what the code does? For example, should I provide the MATLAB code and explain what it's doing line by line? Or, should I just provide the math/algorithm, explain it in plain English, and let the C developer implement it with this understanding in his/her own way (e.g. can I assume the developer understands how to work with complex math (i.e. imaginary numbers), how to generate histograms, perform an FFT, etc.)? Or, is there a better method? I expect I'm not the first to need to do this, so I wonder if any C developers out there ran into this situation and can share any conventional wisdom how they'd like this task to be transferred? Thanks in advance for any comments.

• How to allow all except part 1 and part 2 ?

  - by Stackfan

  This allows me to get easyly dynamic input variables instead of putting a static prefix like /en/etcetcetc, but the problem is all controllers are blocked. Everything goes to index/index. Question: How can i tell this rule allow evertying as it is now, but do not track if it contains http://site.com/donotcatch/me and http://site.com/iamnotbelongstodynamic1/blabla protected function _initRoutes() { ... $dynamic1 = new Zend_Controller_Router_Route( '/:variable0/:variable1', array( 'controller' => 'index', 'action' => 'index'), array( 'variable0' => '^[a-zA-Z0-9_]*$', 'variable1' => '^[a-zA-Z0-9_]*$', ) ); Follow up: Normally, i always belive yes we can, so, we can do that like this where dynamic1 does not the inter-fare with my other static controllers: // http://site/yeswecan/blabla // variable0 = yeswecan // variable1 = blabla $dynamic1 = new Zend_Controller_Router_Route( '/:variable0/:variable1', array( 'controller' => 'index', 'action' => 'index'), array( 'variable0' => '^[a-zA-Z]*$', 'variable1' => '^[a-z0-9_]*$', ) ); // http://site/ajax/whatever... // solves it $dynamic2 = new Zend_Controller_Router_Route( '/ajax/:variable0', array( 'controller' => 'ajax', 'action' => '' ), array( 'variable0' => '^[a-zA-Z0-9_]*$', ) ); // http://site/order/whatever... // solves it $dynamic3 = new Zend_Controller_Router_Route( '/order/:variable0', array( 'controller' => 'order', 'action' => ''), array( 'variable0' => '^[a-zA-Z0-9_]*$', ) ); Note: Still the controllers are getting failed for example http://site/ajax/whatever always goes to /ajax/index where i wanted to send it as /ajax/user-inserted-value How can i fix the $dynamic2 and $dynamic3 by keeping $dynamic1 ??

• Processing a database queue across multiple threads - design advice

  - by rwmnau

  I have a SQL Server table full of orders that my program needs to "follow up" on (call a webservice to see if something has been done with them). My application is multi-threaded, and could have instances running on multiple servers. Currently, every so often (on a Threading timer), the process selects 100 rows, at random (ORDER BY NEWID()), from the list of "unconfirmed" orders and checks them, marking off any that come back successfully. The problem is that there's a lot of overlap between the threads, and between the different processes, and their's no guarantee that a new order will get checked any time soon. Also, some orders will never be "confirmed" and are dead, which means that they get in the way of orders that need to be confirmed, slowing the process down if I keep selecting them over and over. What I'd prefer is that all outstanding orders get checked, systematically. I can think of two easy ways do this: The application fetches one order to check at a time, passing in the last order it checked as a parameter, and SQL Server hands back the next order that's unconfirmed. More database calls, but this ensures that every order is checked in a reasonable timeframe. However, different servers may re-check the same order in succession, needlessly. The SQL Server keeps track of the last order it asked a process to check up on, maybe in a table, and gives a unique order to every request, incrementing its counter. This involves storing the last order somewhere in SQL, which I wanted to avoid, but it also ensures that threads won't needlessly check the same orders at the same time Are there any other ideas I'm missing? Does this even make sense? Let me know if I need some clarification.

• How to setPage() a JEditorPane with a localfile which is outside of the .jar file?

  - by Jaguar

  My program has the following path in the .jar file src/test/Program.class and my program is as follow... Program.java package test; import java.io.File; import java.io.IOException; import javax.swing.JEditorPane; import javax.swing.JFrame; public class Program { JEditorPane editorPane; public Program() { File file = new File("temp.htm"); try { file.createNewFile(); editorPane = new JEditorPane(); editorPane.setPage(Program.class.getResource("temp.htm")); } catch (IOException e) { e.printStackTrace(); } } public JEditorPane getEditorPane(){ return editorPane; } public static void main(String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(400, 400); frame.setVisible(true); Program p = new Program(); frame.getContentPane().add(p.getEditorPane()); } } The problem is that I have compiled the program in a .jar file. The file.createNewFile(); creates the temp.htm file outside the .jar file So when editorPane.setPage(Program.class.getResource("temp.htm")); is called the file is not found as it searches for file inside the test package. How to setPage() the temp.htm file whiich is outside the .jar file but in the same folder as the .jar file? As the temp.htm is a localfile and I want a relative path instead of an absolute path. Thanks.

• Display and Use Advanced Find for Product Subscriptions by Account in Microsoft CRM 4.0

  - by Chris

  By default when viewing an account in edit mode you have access to Opportunities, Invoices, and Quotes which contain the products being shopped by the account and/or the sales department. I'm trying to determine where to store, display, and use the products that an account has a subscription too. I may not understand the implementation but it seems that there should be "Products" option directly off the root Account management window that will show the user all the products the account has purchased. We are trying to integrate this with our production tracking system where product sales can originate from other channels that will not flow through CRM first. This product subscription does not fit into the Opportunity, Quote, or Invoice model because they are confirmed recurring sales that were automatically purchased via tools like a Public Website, Portal, etc. By enabling this tracking in CRM we can use the advanced find feature to facilitate follow up sales and marketing efforts. Example: Find everyone who is subscribed to model A, so we can notify them of a new holiday campaign where they can get 10% off on all add-ons. It's my assumption that this is a common scenario, however I'd like to better understand how to approach this within the world of Microsoft CRM. Thank you in advance.

• Why isn't this company contacting me? [closed]

  - by Alan

  I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

• IE8 problems with .animate() of opacity property - descendant remains opaque throughout

  - by Fabian

  Basically I have something like this: <ul> <li> <a> <div class="trigger-layer"></div> <div class="title-layer">Text here</div> <div class="hover-layer"></div> </a> </li> </ul> I use jQuery to animate the <ul> as follow: $ul = xxx (where I assign the selector to var $ul) $ul.animate({opacity: 0}, 1000, function() {$ul.css("display", "none")}); However in IE8, as the <ul> fades off, the <div class="title-layer">Text here</div> remains clear and opaque. Finally the animation ends, the display: none; property is applied onto the <ul> and the text disappears aburptly.

• ASP .NET Button event handlers do not fire on the first click, but on the second click after a PostB

  - by John

  Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired. Any ideas? Example of Button Definition (within GetAdministrationInterface) public override Control GetAdministrationInterface() { // more code... Button btn = new Button(); btn.Text = "Click Me!"; btn.Click += new EventHandler(Btn_Click); // more code... } Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something } Page_Load Method that calls GetAdministrationInterface protected void Page_Load(object sender, System.EventArgs e) { if (!Page.IsAsync) { List<AdministrationInterface> interfaces = <DATABASE CALL>; foreach(AdministrationInteface ai in interfaces) { placeholderDiv.Controls.Add(ai.GetAdministrationInterface()); } } }

• Given the Following List (UL), how can it be serialized and sent to the Database

  - by nobosh

  I have the follow structure which is created with a nested sortable: <UL id="container"> <LI id="main1"> <input type="checkbox" /> Lorem ipsum dolor sit amet, consectetur <UL> <LI id="child2"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> </UL> </LI> <LI id="main3"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> <LI id="main4"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> <LI id="main5"> <input type="checkbox" /> In hac habitasse platea dictumst. <UL></UL> </LI> </UL> Where I'm stuck is how to send this back to the database. I"m guessing that it needs to be serialized, does that sound right to? so that is looks something like: item[]=main1&item[]=221&item_221[]=21&item_221[]=2&item_221[]=211&item[]=22 I'm a little lost at this point and appreciate any tips to move me in the right direction. Thanks, B

• Read char from txt file in C++

  - by Jack in the Box

  I have a program that will read the number of rows and columns from a txt file. Also, the program has to read the contents of a 2D array from the same file. Here is the txt file 8 20 * * *** *** 8 and 20 are the number of rows and columns respectively. The spaces and asterisks are the contents of the array, Array[8][20] For example, Array[0][1] = '*' I did make the program reading 8 and 20 as follow: ifstream myFile; myFile.open("life.txt"); if(!myFile) { cout << endl << "Failed to open file"; return 1; } myFile >> rows >> cols; myFile.close(); grid = new char*[rows]; for (int i = 0; i < rows; i++) { grid[i] = new char[cols]; } Now, how to assign the spaces and the asterisks to to the fields in the array? I hope you got the point.

• Bizzare results when running two Visual Studio Express C++ 2008 solutions

  - by Jamie Keeling

  This is a follow on from my previous question although this is about something else. I've been having a problem where for some reason my message that I pass from one process to another only displays the first letter, in this case "M". My application based on a MSDN sample so to make sure I hadn't missed something I create a seperate solution, added the MSDN sample (Without any changes for my needs) and unsuprisingly it works fine. Now for the weird bit, when I run the MSDN sample running (As in debugging) and have my own application running, the text prints out fine without any problems. The second I run my on it's own without the original MSDN sample being open it fails to work and only shows an "M". I've looked in the debugger and don't seem to notice anything suspicious (It's a slightly dated picture, I've fixed the data type inconsistency). Can anyone provide a solution as to this? I've never encountered anything like this before. To look at my source code it's easier to just look at the link I posted at the top of the question, there's no point in me posting it twice. Thank you for any help.

• Has anyone ever had OpenCV work with Python 2.7 on MacOS 10.6?

  - by ?????

  I've been trying on and off for the past 6 months to get OpenCV to work with Python on MacOS. Every time there's a new release, I try again and fail. I've tried both 64-bit and 32-bit, and both the xcode gcc and gcc installed via macports. I just spend the past two days on it, hopeful that the latest OpenCV release, that appears to include Python support directly would work. It doesn't. I've also tried and failed to use this: http://code.google.com/p/pyopencv/ I've been using OpenCV with C++ or Microsoft C++/CLI for the past few years, but I'd love to use it with Python on a Mac because that is my primary development environment. I'd love to hear from anyone who's actually been able to get the opencv python examples to run under Mac OS 10.6, either 32 or 64-bit. My last attempt was to follow the instructions on this page http://recursive-design.com/blog/2010/12/14/face-detection-with-osx-and-python/ with a clean, fresh install of 10.6 on a 64-bit capable Mac. My PYTHONPATH is set, and I can see the cv library in it. But an "import cv" from python fails. Previously, the closest I've ever gotten (again, staring on a clean, fresh 10.6 install) was this: Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import cv Fatal Python error: Interpreter not initialized (version mismatch?) Abort trap thrilllap-2:~ swirsky$ I've seen a lot of folks answering similar questions here, but have never seen an definitive answer for it.

• Images in IFRAME no longer showing after I log out of Flickr?

  - by contact-kram

  I have a iframe window which displays user's flickr images. I use the flickr.photos.search api to download the user's image from flickr. This works great when the user is logged into flickr. But when I explicitly log off the user from flickr and the yahoo network and then attempt to download the flickr images, I get redirected to www.yahoo.com in a full browser window (not in my iframe). If I remember correctly, I did not have this issue when I was not using iframes and I was being redirected to the yahoo login screen. Any suggestions? To elaborate, this URI - http://www.flickr.com/services/api/auth.howto.web.html, lists the below step - Create an auth handler When users follow your login url, they are directed to a page on flickr.com which asks them if they want to authorize your application. This page displays your application title and description along with the logo, if you uploaded one. When the user accepts the request, they are sent back to the Callback URL you defined in step 2. The URL will have a frob parameter added to it. For example, if your Callback URL was http://test.com/auth.php then the user might be redirected to http://test.com/auth.php?frob=185-837403740 (The frob value in this example is '185-837403740'). This does not happen when I am in my iframe window but it does happen in my full browser window.

• How to set buffer size in client-server app using sockets?

  - by nelly

  First of all i am new to networking so i may say dumb thing in here. Considering a client-server application using sockets(.net with c# if that matters). The client sends some data, the server process it and sends back a string. The client sends some other data, the serve process it, queries the db and sends back several hundreds of items from the database The client sends some other type of data and the server notifies some other clients . My question is how to set the buffer size correctly for reading/writing operation. Should i do something like this: byte[] buff = new byte[client.ReceiveBufferSize] ? I am thinking of something like this: Client sends data to the server(and the server will follow the same pattern) byte[] bytesToSend=new byte[2048] //2048 to be standard for any command send by the client bytes 0..1 ->command type bytes 1..2047 ->command parameters byte[] bytesToReceive=new byte[8]/byte[64]/byte[8192] //switch(command type) But..what is happening when a client is notified by the server without sending data? What is the correct way to accomplish what i am trying to do? Thanks for reading.

• [C#] how to do Exception Handling & Tracing

  - by shrimpy

  Hi all, i am reading some C# books, and got some exercise don't know how to do, or not sure what does the question mean. Problem: After working for a company for some time, your skills as a knowledgeable developer are recognized, and you are given the task of “policing” the implementation of exception handling and tracing in the source code (C#) for an enterprise application that is under constant incremental development. The two goals set by the product architect are: 100% of methods in the entire application must have at least a standard exception handler, using try/catch/finally blocks; more complex methods must also have additional exception handling for specific exceptions All control flow code can optionally write “tracing” information to assist in debugging and instrumentation of the application at run-time in situations where traditional debuggers are not available (eg. on staging and production servers). (i am not quite understand these criterias, i came from the java world, java has two kind of exception, check and unchecked exception. Developer must handle checked exception, and do logging. about unchecked exception, still do logging maybe, but most of the time we just throw it. however here comes to C#, what should i do????) Question for Problem: List rules you would create for the development team to follow, and the ways in which you would enforce rules, to achieve these goals. How would you go about ensuring that all existing code complies with the rules specified by the product architect; in particular, what considerations would impact your planning for the work to ensure all existing code complies?

• [LaTeX] positions of page numbers, position of chapter headings, chapters AND Table of Contents, Ref

  - by kaikanmonaco

  I am writing my PhD thesis (120+ pages) in latex, the deadline is approaching and I am struggling with layout problems. I am using the documentstyle book. I am posting both problems in this one thread because I am not sure if the solution might be related to both problems or not. Problems are: 1.) The page numbers are mostly located on the top-right of each page (this is correct and where I want them to be). However, only on the first page of chapters and on the first page of what I call "special chapters", the page number is located bottom-centered. With "special chapters" I mean: List of Contents, List of Figures, List of Tables, References, Index. My university will not accept the thesis like this. The page number must ALWAYS be top-right one each page, even if the page is the first page of a chapter or the first page of something like the List of Contents. How can I fix this? 2.) On the first page of chapters and "special chapters" (List of Contents...), the chapter title is located far too low on the page. This is the standard layout of LaTeX with documentstyle book I think. However, the chapter title must start at the very top of the page! I.e. the same height as the normal text on the pages that follow. I mean the chapter title, not the header. I.e., if there is a chapter called "Chapter 1 Dynamics of foobar under mechanical stress" then that text has to start from the top the page, but right now it starts several centimeters below the top. How can I fix this? Have tried all kinds of things to no effect, I'd be very thankful for a solution! Thanks.

• How can I efficiently manipulate 500k records in SQL Server 2005?

  - by cdeszaq

  I am getting a large text file of updated information from a customer that contains updates for 500,000 users. However, as I am processing this file, I often am running into SQL Server timeout errors. Here's the process I follow in my VB application that processes the data (in general): Delete all records from temporary table (to remove last month's data) (eg. DELETE * FROM tempTable) Rip text file into the temp table Fill in extra information into the temp table, such as their organization_id, their user_id, group_code, etc. Update the data in the real tables based on the data computed in the temp table The problem is that I often run commands like UPDATE tempTable SET user_id = (SELECT user_id FROM myUsers WHERE external_id = tempTable.external_id) and these commands frequently time out. I have tried bumping the timeouts up to as far as 10 minutes, but they still fail. Now, I realize that 500k rows is no small number of rows to manipulate, but I would think that a database purported to be able to handle millions and millions of rows should be able to cope with 500k pretty easily. Am I doing something wrong with how I am going about processing this data? Please help. Any and all suggestions welcome.

• Do vs. Run vs. Execute vs. Perform verbs

  - by coffeeaddict

  Before anyone starts to go nuts and red flag this post saying this is "Subjective" which drives me absolutely nuts because everyone has their own intent why they are posting something others feel are subjective. Subjective is subjective to each person, how about that! So with that let me tell you a couple things so that this post does not get flagged by flag happy moderators: 1) There are community guidlines on specific keywords recommended by certain organizations or people (e.g. Microsoft, Lance Hunt, etc.) 2) I want to know what others are using the most and why. Why they feel this verb reads better than others 3) Books even talk about this verb issue (Uncle Bob, etc.), so it's not subjective Now to my actual question: a) What list of verbs are you using for method names? What's your personal or team standard? b) I debate whether to use Do vs. Run vs. Execute vs. Perform and am wondering if any of these are no longer recommended or some that people just don't really use and I should just scratch them. Basically any one of those verbs mean the same thing...to invoke some process (method call). This is outside of CRUDs. For example: ExecutePayPalWorkflow(); that could be also any one of these names instead: DoPayPalWorkflow(); RunPayPalWorkflow(); PerformPayPalWorkflow(); or does it not really matter...because any of those verbs pretty much are understandable as to "what" shows your intent by the other words that follow it "PayPalWorkflow" This discussion can go for any language. I just put the two main tags C# and Java here which is good enough for me to get some solid answers or experiences.

• where are the frameworks for creating libraries?

  - by fayer

  whenever i create a php library (not a framework) i tend to reinvent everything everytime. "where to put configuration options" "which design pattern to use here" "how should all the classes extend each other" and so on... then i think, isn't there a good library framework to use anywhere? it's like a framework for a web application (symfony, cakephp...) but instead of creating a web application, this framework will help coder to create a library, providing all the standard structure and classes (observer pattern, dependency injection etc). i think that will be the next major thing if not available right now. in this way there will be a standard to follow when creating libraries, or else, it's like a djungle when everyone creates their own structure, and a lot of coders just code without thinking of reusability etc. there isn't any framework for creating libraries at the moment? if not, don't u agree with me that this is the way to do it, with a library framework? cause i am really throwing a lot of time (weeks!) just thinking about how to organize things, both in code and file level, when i should just start to code the logic. share your thoughts!
