• Storing DateTime (UTC) vs. storing DateTimeOffset

  - by Frederico

  I usually have an "interceptor" that right before reading/writing from/to the database does datetime conversion (from UTC to localtime, and from localtime to utc), so I can use DateTime.Now (derivations and comparisions) throughout the system without worrying about timezones. Regarding serialization and moving data between computers, there is no need to bother, as the datetime is always UTC. Should I continue storing my dates (SQL 2008 - datetime) in UTC format or should I instead store it using DateTimeOffset (SQL 2008 - datetimeoffset)? UTC Dates in the database (datetime type) have been working and known for so long, why change it? What are the advantages? I have already looked into articles like this one, but I'm not 100% convinced though. Any thoughts?

• How to keep the popup menu of a JComboBox open on populating it ?

  - by Stormshadow

  I have a JComboBox on my Panel. One of the popup menu items is 'More' and when I click that I fetch more menu items and add them to the existing list. After this, I wish to keep the popup menu open so that the user realizes that more items have been fetched however, the popup closes. The event handler code I am using is as follows public void actionPerformed(ActionEvent e) { if (e.getSource() == myCombo) { JComboBox selectedBox = (JComboBox) e.getSource(); String item = (String) selectedBox.getSelectedItem(); if (item.toLowerCase().equals("more")) { fetchItems(selectedBox); } selectedBox.showPopup(); selectedBox.setPopupVisible(true); } } private void fetchItems(JComboBox box) { box.removeAllItems(); /* code to fetch items and store them in the Set<String> items */ for (String s : items) { box.addItem(s); } } I do not understand why the showPopup() and setPopupVisible() methods are not functioning as expected.

• Ensuring dynamically added Dojo Dijits are registered in the DOM.

  - by Pro777

  I need to dynamically create Dijits to add N rules to a particular form. Currently I am adding them with the following javascript. var value = new dijit.form.Select({ id: "value_" + counter, store: ValueStore, searchAttr: "description" }, "stateSelect" + counter); value.placeAt(form, "last"); value.startup(); This is creating the element correctly in the form, but it is not associated when the form actually posts. I know Dojo is recognizing the Dijit because the styling is correct. How can I make sure they are included in the DOM form?

• Finding unique elements in an string array in C

  - by LuckySlevin

  Hi, C bothers me with its handling of strings. I have a pseudocode like this in my mind: char *data[20]; char *tmp; int i,j; for(i=0;i<20;i++) { tmp = data[i]; for(j=1;j<20;j++) { if(strcmp(tmp,data[j]))//then except the uniqueness, store them in elsewhere. } } But when i coded this the results were bad.(I handled all the memory stuff,little things etc.) The problem is in the second loop obviously :D. But i cannot think any solution. How do i find unique strings in an array. Example input : abc def abe abc def deg entered unique ones : abc def abe deg should be found.

• How to structure (normalize?) a database of physical parameters?

  - by Arrieta

  Hello: I have a collection of physical parameters associated with different items. For example: Item, p1, p2, p3 a, 1, 2, 3 b, 4, 5, 6 [...] where px stands for parameter x. I could go ahead and store the database exactly as presented; the schema would be CREATE TABLE t1 (item TEXT PRIMARY KEY, p1 FLOAT, p2 FLOAT, p3 FLOAT); I could retrieve the parameter p1 for all the items with the statement: SELECT p1 FROM t1; A second alternative is to have an schema like: CREATE TABLE t1 (id INT PRIMARY KEY, item TEXT, par TEXT, val FLOAT) This seems much simpler if you have many parameters (as I do). However, the parameter retrieval seems very awkward: SELECT val FROM t1 WHERE par == 'p1' What do you advice? Should go for the "pivoted" (first) version or the id, par, val (second) version? Many thanks.

• Embarrassingly parallel workflow creates too many output files

  - by Hooked

  On a Linux cluster I run many (N > 10^6) independent computations. Each computation takes only a few minutes and the output is a handful of lines. When N was small I was able to store each result in a separate file to be parsed later. With large N however, I find that I am wasting storage space (for the file creation) and simple commands like ls require extra care due to internal limits of bash: -bash: /bin/ls: Argument list too long. Each computation is required to run through a qsub scheduling algorithm so I am unable to create a master program which simply aggregates the output data to a single file. The simple solution of appending to a single fails when two programs finish at the same time and interleave their output. I have no admin access to the cluster, so installing a system-wide database is not an option. How can I collate the output data from embarrassingly parallel computation before it gets unmanageable?

• MATLAB: draw centroids

  - by Myx

  Hello - my main question is given a feature centroid, how can I draw it in MATLAB? In more detail, I have an NxNx3 image (an rgb image) of which I take 4x4 blocks and compute a 6-dimensional feature vector for each block. I store these feature vectors in an Mx6 matrix on which I run kmeans function and obtain the centroids in a kx6 matrix, where k is the number of clusters and 6 is the number of features for each block. How can I draw these center clusters in my image in order to visualize if the algorithm is performing the way I wish it to perform? Or if anyone has any other way/suggestions on how I can visualize the centroids on my image, I'd greatly appreciate it. Thank you.

• How to handle updating JDO class definitions on Google App Engine

  - by Spines

  I'm using the Google app engine and JDO. What is the best way to update a JDO class definition without having to wipe the data store contents first? I'm not sure if this is specific to JDO on GAE, but I noticed that when I simply change the name of one of my persistent fields from svotes to votes, an exception is thrown (java.lang.NoSuchFieldError: svotes). I expect once my site goes live I might want to make some changes to my JDO class definitions, such as adding a field or something. Any suggestions for how to update the data definitions without having to wipe the database?

• Scala downwards or decreasing for loop?

  - by Felix

  In scala, you often use an iterator to do a for loop in an increasing order like: for(i <- 1 to 10){ code } How would you do it so it goes from 10 to 1? I guess 10 to 1 gives an empty iterator (like usual range mathematics)? I made a scala script which solves it by calling reverse on the iterator, but it's not nice in my opinion, is this the way to go: def nBeers(n:Int) = n match { case 0 => ("No more bottles of beer on the wall, no more bottles of beer."+ "\nGo to the store and buy some more, "+ "99 bottles of beer on the wall.\n") case _ => (n+" bottles of beer on the wall, "+n +" bottles of beer.\n"+"Take one down and pass it around, "+ (if((n-1)==0) "no more" else (n-1))+ " bottles of beer on the wall.\n") } for(b <- (0 to 99).reverse)println(nBeers(b)) ?? Any comments/suggestions?

• Ant var and property scope

  - by bobtheowl2

  I have a main build script that calls various targets. One of these targets needs to store a value and another target needs to display it. Obviously this is not working so I think it may be related to scope. I've tried var, property, and declaring the property outside of target1. Since var seems to be mutable, it looks like I need to use it instead, but each time my output is empty. Main script <antcall target="target1"/> <antcall target="display"/> In target1: <var name="myVar" value="${anotherVar}"/> In display: <echo>${myVar}</echo>

• Ask StackOverFlow : Canny a LightWeight Authorization library in Java

  - by eltados

  In the course of my work i need to develop an authorization engine ( i'm already authenticated and i check access of a user to an action ) in order to store all the authorization logic inside a same place and be able to reuse it and i have created the mini library. http://github.com/eltados/canny (updated) what do you think about it? What are the limits of my approch ? Do you understand the benefit or it? Is there any lightweight Authorization engine library i could have a look at? I had a look at spring security and it does not really answer my requirement. The main idea is that i want to be able to reuse the same code to controll access in the controllers and the views.

• dojo 1.4: difference in tree html rendering

  - by Fell

  Hi, I have written an application using dojo 1.3 in which i have used the dijit tree. I am loading the tree with json data specified in the store which is in turn used by the tree model. In the 1.3 version the tree elements pick up the id directly from the json data.However in 1.4 the tree elements have their own id which is something like dijit__treenode_4. The id's that I have specified in json are unique and im not able to understand why these are not being used anymore. Please help me understand how this functionality has changed and how I can override the automatic id generation.. Thanks in advance, Fell

• Open Safari from within Opera Mini on the iPhone

  - by Ican Zilb

  Now that Opera Mini is becoming so popular in the App store I want to effectively warn my web site visitors that the rendition they see in Opera Mini is far from what I meant them to see and redirect them to my page in Mobile Safari, so they can enjoy HTML5 and CSS3. I've been banging my head around that task all day long, but I can't seem to find a solution. My hope lies in the custom URL schemes, but seems Opera Mini handles all schemes which usually Safari does. Would be great if there's a scheme like safari://www.domain.com which opens ONLY in Safari, so I can redirect the visitors to it. Does anybody know a solution to that problem? --edit Just to make myself clear - browser detection is not the problem (I'm doing Javascript for 13 years now) the question is if there's a way to invoke the Safari app on the iPhone from within a web page which is being viewed in Opera Mini.

• What's the best way to return a random line in a text file using C?

  - by jeremy Ruten

  What's the best way to return a random line in a text file using C? It has to use the standard I/O library (<stdio.h>) because it's for Nintendo DS homebrew. Clarifications: Using a header in the file to store the number of lines won't work for what I want to do. I want it to be as random as possible (the best being if each line has an equal probability of being chosen as every other line.) The file will never change while the program is being run. (It's the DS, so no multi-tasking.)

• business object and codelist

  - by feiroox

  Hi How to design a business object? I have a library which returns me an Object which have ten lists of other different objects. I need to store it into database all. List of objects are often like: class Item { private int id; private String name; private double point; } But the name is often the same. Like basic title of the product or code. Containing from 3 characters up to 70characters. Should I make conversion for every Object to: (or something similar) class ConvertedItem { private int id; private int code; private double point; } And have a separated table of codes ( I guess around 60). Or do not bother with duplicated stuff? It's not mission critical app. What would you do in my case? thanks in advance

• ORM on iPhone. More simple than CoreData.

  - by Alexander Babaev

  The question is rather simple. I know that there is SQLite. There is Core Data also. But I need something in between. More object-oriented than SQLite API and simplier than Core Data. Main points are: I need access to stored entities only by id. No queries required. I need to store items of a single type, it means that I can use only one table if I choose SQLite. I want automatic object-relational conversion. Or object-storage if the storage is not relational. I can use object archiving, but I have to implement things (NSArchiver). But I want to write some kind of class and get persistence automatically. As it can be done with Hibernate/ActiveRecord/Core Data/etc. Thanks.

• php database session handling problem in IE8!

  - by psyb0rg

  I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

• Searching a 2D array for a range of values in java

  - by Paige O

  I have a 2^n size int array and I want to check if an element exists that is greater than 0. If the element exists, I want to divide the array by 4 and check if the coordinates of the found element are in the 1st, 2nd, 3rd or 4th quadrant of the array. For example, logically if the element exists in the first quadrant it would look something like this: If array[][] 0 && the row of that coordinate is in the range 0-(grid.length/2-1) && the column of that coordinate is in the range 0-(grid.length/2-1) then do something. I'm really not sure how to check the row and column index of the found element and store those coordinates to use in my if statement. Help!

• How to configure a has_many association with non-ActiveRecord model

  - by Callmeed

  My Rails app has a normal ActiveRecord "Account" model stored in the database. The model will store the URL to a remote XML file which defines some other objects. For example, the Account has_many :galleries but the Gallery model is simply defined by nodes in the XML document. So how do I get /accounts/1/galleries to show the galleries from that account's XML? How do I setup this relationship? I know how to do basic non-AR models, but I'm not sure how to define the association or if I need to create a Gallery model at all.

• How to return table name from stored procedure in dataset.

  - by Shantanu Gupta

  I used a dataset to store 15 tables that I need at the time of loading. When i filled all the tables using stored procedure it returns me all the table but name of the table doesn't comes as that of actual table name in a database. It takes all the table with table name as Table1, Table2, Table3... I want them to be with the name as they actually are in table. SELECT PK_GUEST_TYPE, [DESCRIPTION] FROM L_GUEST_TYPE SELECT PK_AGE_GROUP_ID, AGE_GROUP FROM L_AGE_GROUP SELECT PK_COMPANY_ID, COMPANY_NAME FROM M_COMPANY SELECT PK_COUNTRY_ID, COUNTRY FROM L_COUNTRY SELECT PK_EYE_COLOR_ID, [DESCRIPTION] FROM L_EYE_COLOR SELECT PK_GENDER_ID, [DESCRIPTION] FROM L_GENDER SELECT PK_HAIR_COLOR_ID, [DESCRIPTION] FROM L_HAIR_COLOR SELECT PK_STATE_PROVONCE_ID, [DESCRIPTION] FROM L_STATE_PROVINCE SELECT PK_STATUS_ID, [DESCRIPTION] FROM L_STATUS SELECT PK_TITLE_ID, [DESCRIPTION] FROM L_TITLE SELECT PK_TOWER_ID, [DESCRIPTION] FROM M_TOWER SELECT PK_CITY_ID, [DESCRIPTION] FROM L_CITY SELECT PK_REGISTER_TYPE_ID, [DESCRIPTION] FROM L_REGISTER_TYPE Here is my frontend coding to fill dataset.

• Core Data data type for just the date - not including time

  - by Jason

  I am new at Core Data, and it seems like it is a great way to manage the data store. However I am also very memory-conscious due to the fact that the iPhone doesn't have that much of it. I was a little surprised to see that the data types are so limited - eg. there is a Date type which includes also the time, but no Date type for just the date! All the time information takes up precious bytes of memory, if I just wanted an attribute with the date (e.g. 2/15/2010 rather than 2/15/2010 02:34:48), how could I do this? Is it possible?

• Handling Incoming Data from Multiple Sockets in Python

  - by user859434

  Background: I have a current implementation that receives data from about 120 different socket connections in python. In my current implementation, I handle each of these separate socket connections with a dedicated thread for each. Each of these threads parse the data and eventually store it within a shared locked dictionary. These sockets DO NOT have uniform data rates, some sockets get more data than others. Question: Is this the best way to handle incoming data in python, or does python have a better way on handling multiple sockets per thread?
