This page provides you a list of top 5 JavaScript frameworks. Though I am not sure if they are the top 5, which is always arguable, I am very sure that those frameworks are good and useful.
David Walsh is Mozilla’s senior web developer, and the core developer for the MooTools Javascript Framework. David’s blog reflects his skills in HTML/5, JS and CSS, and offers a ton of engaging advice and insight into front-end technologies. Even more obvious is his passion for open source contribution and trial-and-error development, making his blog one of the most honest and engaging around. Website: davidwalsh.name

Recently one of the applications that I developed started throwing exceptions, that had the following message: SQL state [72000]; error code [1013]; ORA-03111: break received on communication channel When I googled around, I couldn't come across anything useful. Sadly enough most of the sites just showed the documentation for that error, without any explanation from anyone experiencing that issues. So here you go, with the best possible explanation that I could come up with. My application sets two things on the connection that is throwing this exception: It sets the fetchSize to be 2500 rows It sets the query timeout to be 10 seconds The database server and the application are separated over a long latency network (actually there is a NetEm box that emulates the long latency between these two boxes) which has a latency characteristic of 50+/-5 milliseconds. This is the whole setup. It is important to understand how the timeout is handled by the Oracle client (in my case JDBC clien...
I ran into what I thought as an issue while I was using the sequence ID generation strategy in JPA. The JPA provider I am using is Hibernate. I think sharing my experience will save someone some time. To use a sequence (For e.g. Oracle sequence) to generate values and assign them to the ID field of your persistence object, you will following something like this: @Id @Column(name = "ITEM_ID") @GeneratedValue(strategy = GenerationType.SEQUENCE, generator="ItemIdSeqGenerator") @SequenceGenerator(name="ItemIdSeqGenerator", sequenceName="ITEM_ID_SEQ", allocationSize=1) private long itemId; This means the following things: The @Id annotation says that the field itemId is a primary key. The @Column annotation says that the corresponding column in the database is ITEM_ID. The @GeneratedValue says that the value that needs to be populated in the itemId should be generated, while that object is persisted. The strategy to generate the value is to...
You can view and edit the configuration of your guest OSs using the vboxmanage command. To view the list of guest OSs you have, give the following command: C:\Program Files\Sun\xVM VirtualBox>VBoxManage.exe list vms VirtualBox Command Line Management Interface Version 2.2.2 (C) 2005-2009 Sun Microsystems, Inc. All rights reserved. "MySolaris" {dc6dc85f-5583-4a1b-bf3e-969941a2cd91} "Ubuntu" {eb973bbf-d86e-4579-85eb-6ea2cd12bf95} "Debian" {3e784597-89d8-4f17-90cb-63e866c651a3} "openSUSE" {6862884e-60e1-4c65-8aab-b57ec38a3922} "Debian-Lenny" {4b561432-abac-4a27-a501-b42af956b96b} To view the specific guest, you can use the UUID of the guest. For e.g. C:\Program Files\Sun\xVM VirtualBox>VBoxManage.exe showvminfo eb973bbf-d86e-4579-85eb-6ea2cd12bf95 VirtualBox Command Line Management Interface Version 2.2.2 (C) 2005-2009 Sun Microsystems, Inc.
