TIL: Keeping parent directory structure while copying

There had been instances when I wanted to copy "/home/roy" to a target directory "/target" as "/target/home/roy". I used to do some scripting foo to get this done. A few days back, I learned this cool option called "--parents" in cp command that will preserve the parent directory structure while copying. Made my life a lot easier on one of my backup tasks.

even though I've programmed, even in assembly code, and yes used bash, and linux etc in the past. I wound up deleting my virtual machine attempts as after all the thought that was put into getting DSL or any version working was complete, no one considered that someone might want to surf safely, get a file, then put that file in the host OS EASILY with no hassles. No hooking up two machines to network, or pen drives that don't show up etc. Someone who just wants to use linux that wants to move all their files around in that world is fine. But it shouldn't take more than 24 hours to figure out how to transfer a downloaded file through virtualbox to windows for example. And it's not about being "smart", otherwise they'd made you type a bunch of bash commands just to launch the games or pre-installed firefox. And you can resize the resolution, but then your usb mouse won't work... talking latest modern hardware here. idk, maybe it all works great on a 1992 computer. But I should be able to download a file, mount a usb thumb drive, tell it to move that file to the thumb drive, then lose scope and give mouse to host, then grab it. Better, are the menus that have host to machine, machine to host, and bi-directional. THEY SHOULD WORK!

The mysterious ORA-03111 error

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...

Note on allocationSize parameter of @SequenceGenerator while using JPA

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.
