malloc

in C or

 new SomeClass()

in C++. I’m almost finished with a memory manager in C so hopefully I can get a self-hosted system soon.
Alternatively, when I’m not doing OS development, I’m improving my Java multithreading and network programming skills. I recently wrote a library for “hooking up” multiple services via multicast and being able to pass around messages in a bus-like fashion. It’s very rudimentary but it was helpful in learning Java threading and networking. I’ll post the source up here when it’s more mature.
Thanks for reading and have a Happy Independence Day!

I had a need for a simple application to store information about ICs and other electronic components I have in my possession, so I thought I’d give Java a try! After figuring out Eclipse’s designer windows and GUI editing helpers, I was able to create an application that is usable and backed by a SQLite3 database. My application is cheesily named ‘ICDB’, short for IC Database. I plan on putting the source on GitHub in a little while, and I will post it here as well. Some of the neat features I’ve been able to implement are:

• Search as you type – results come up in the main table as you type a term into the search box
• Application wide key bindings – ctrl-N brings up the ‘New Part’ window, ctrl-M maximizes things, etc.
• Export to Text and CSV
• Add, edit, delete functionality for the database
• Sortable rows in the main table – even after searching, you can sort the subset of items

From my limited experience, I like Java. Some things I miss from C++ like multiple-inheritance, but for the most part I can make do with Interfaces, Abstract classes and the other OOP features. 

UPDATE
I have put the source on Github. The pre-built JAR and the dependency JAR is there if you’d like to build it yourself! Documentation is soon to come!
