Font face customization in Emacs - an easy way

I usually edit source code using Emacs running inside a PuTTY session. One of the struggles I often run into is how to customize different elements I see on the screen. For e.g. the prompt in the shell-mode, previously executed command line, shell input, etc.

While I googled around a bit, I came across this incredibly useful key binding: C-u C-x =. It runs the command "what-cursor-position". Here is how you can use this: You position the cursor on the element you would like to customize, and type C-u C-x =. You will be presented with the properties of the character at point, including links to customize the character.

I find this extremely useful and hope sharing this information will help others as well.

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.
