How does one use TrafficStats.incrementOperationCount()?

- by Dheeraj

The documentation for TrafficStats.incrementOperationCount() says: Increment count of network operations performed under the given accounting tag. This can be used to derive bytes-per-operation. I want to find the total number of bytes transferred during a particular network operation. Since this API claims to help in deriving bytes-per-operation, can someone help me understand how to use it?

C++, using one byte to store two variables

- by 2di

Hi All I am working on representation of the chess board, and I am planning to store it in 32 bytes array, where each byte will be used to store two pieces. (That way only 4 bits are needed per piece) Doing it in that way, results in a overhead for accessing particular index of the board. Do you think that, this code can be optimised or completely different method of accessing indexes can be used? c++ char getPosition(unsigned char* c, int index){ //moving pointer c+=(index>>1); //odd number if (index & 1){ //taking right part return *c & 0xF; }else { //taking left part return *c>>4; } } void setValue(unsigned char* board, char value, int index){ //moving pointer board+=(index>>1); //odd number if (index & 1){ //replace right part //save left value only 4 bits *board = (*board & 0xF0) + value; }else { //replacing left part *board = (*board & 0xF) + (value<<4); } } int main() { char* c = (char*)malloc(32); for (int i = 0; i < 64 ; i++){ setValue((unsigned char*)c, i % 8,i); } for (int i = 0; i < 64 ; i++){ cout<<(int)getPosition((unsigned char*)c, i)<<" "; if (((i+1) % 8 == 0) && (i > 0)){ cout<<endl; } } return 0; } I am equally interested in your opinions regarding chess representations, and optimisation of the method above, as a stand alone problem. Thanks a lot

Hibernate - One design problem

- by Yatendra Goel

I am learning Hibernate from the tutorial on JBoss website. I have a confusion in a code example located here. There is a Cat class code at 4.1. A simple POJO example. This Cat class has a reference to his mother as private Cat mother; Q1. If the class has an identifier property as id, then wouldn't it be better to store the cat's mother's id instead of cat's mother object. means instead of private Cat mother; wouldn't it be better to have private long motherId; `

JQuery: Combine multiple pages into one

- by k_wave

I am developing an application by using phonegap and jQuery Mobile. Phonegap recommends a single document structure. As 5 divs or more in a document are pretty unclear, I'm trying to split up my pages (the div's) into multiple documents. As soon as phonegap loads the app, I want to insert these documents into the index.html. function loadPage(external_document) { var docname=external_document+".html"; $.get(docname, function(data) { console.log(docname+" loading"); $("body").append($(data).find("body")); $("head").append($(data).find("head")); console.log(docname+" loaded"); }); } document.addEventListener("deviceready", function(){ loadPage("DialogCredentials"); }, false); DialogCredentials.html <html> <head> <script type="text/javascript" src="js/DialogCredentials.js"></script> </head> <body> <div data-role="page" id="dlg_credentials"> <div data-role="header"><h1>Login</h1></div> <div data-role="content"> ... </div> </div> </body> </html> As soon as the loadPage gets executed there should be a <div id="dlg_credentials"… and the corresponding javascript tag in the dom of my main document. But it isn't. There are no errors shown in the web inspector. So what am I doing wrong here?

Hibernate many-to-one - bad usage?

- by DaveA

Just trying out Hibernate (with Annotations) and I'm having problems with my mappings. I have two entity classes, AudioCD and Artist. @Entity public class AudioCD implements CatalogItem { @Id @GeneratedValue(strategy = GenerationType.AUTO) private int id; private String title; @ManyToOne(cascade = { CascadeType.ALL }, optional = false) private Artist artist; .... } @Entity @Table(uniqueConstraints = { @UniqueConstraint(columnNames = { "name" }) }) public class Artist { @Id @GeneratedValue(strategy = GenerationType.AUTO) private int id; @Column(nullable = false) private String name; ..... } I get AudioCD objects from an external source. When I try to persist the AudioCD the Artist gets persisted as well, just like I want to happen. If I try persisting another different CD, but Artist already exists I get errors due to constraint violations. I want Hibernate to recognise that the Artist already exists and shouldn't be inserted again. Can this be done via annotations? Or do I have to manage the persistence of the AudioCD and Artist seperately?

SQL Selecting from one table OR another then joining the two

- by Cyprus106

So this is interesting, and apparently beyond my SQL skillset. I need to select a particular record where an ID="0003" (or whatever) from either table1 or table2 if table1 doesn't have that record. Then I need to join table1 and table2 on a mutual field they both have (field name is Product_ID) I was playing with all sorts of variations of the following, (no, it doesn't work) but after 2 days of groping through the internet and a big SQL book I still can't figure anything out. SELECT ProductStock.Product_ID AS PSID, Products.ID AS PID, ProductStock.*, Products.* FROM ProductStock, Products LEFT JOIN (Products AS Pr) ON Pr.ID=ProductStock.Product_ID WHERE (ProductStock.ID="6003" OR Products.ID="6003")

HTML, Javascript, PHP and Actionscript all in one Eclipse install (2010)

- by ThunderChunky_SF

I just wanted to poll the community and see which plugins people are currently using to get all of these different technologies running in Eclipse. I saw this thread which mentioned Spket & WPT: http://stackoverflow.com/questions/1575617/eclipse-which-plugins-for-html-javascript But I noticed that Spket doesn't seem to have been updated since October of 2009 so I'm wondering if it's still a good tool to use. I'm not sure what would be best for PHP since it seems like some of the tools are disjointed at the moment. For Actionscript I know I can just install the latest Flash Builder plugin and be done. Any suggestions are greatly appreciated.

Retrieve value of one column in a table

- by user327094

Here is my problem: I have 2 tables Accounts and Transaction Logs. in Accounts table, it has column "Amount" which is a base amount of an account. and in Trans Logs table, it also has column "Amount" which is additional (add or minus to the base amount) amount of the account. and I don't know how to retrieve that base amount to edit it, then save it back to the table. That means I need to get a value of the right column by using Acc_No to find. I'm using DataSet, by the way. i think it should go like this: Dim Amount as Decimal Amount = *the code to retrieve the base amount* Amount = Amount + txtAmount.Text *the code to save the new amount back to Accounts table* Thank you!

Clustered index on frequently changing reference table of one or more foreign keys

- by Ian

My specific concern is related to the performance of a clustered index on a reference table that has many rapid inserts and deletes. Table 1 "Collection" collection_pk int (among other fields) Table 2 "Item" item_pk int (among other fields) Reference Table "Collection_Items" collection_pk int, item_pk int (combined primary key) Because the primary key is composed of both pks, a clustered index is created and the data physically ordered in the table according to the combined keys. I have many users creating and deleting collections and adding and removing items to those collections very frequently affecting the "Collection_Items" table, and its clustered index. QUESTION PART: Since the "Collection_Items" table is so dynamic, wouldn't there be a big performance hit on constantly resorting the table rows because of the clustered index ? If yes, what should I do to minimize this ?
