Note: This article is part of my Testing stuff with QEMU series.
MenuetOS is an operating system with a monolithic preemptive, real-time kernel, including video drivers, all written in FASM assembly language, for 64-bit and 32-bit x86 architecture computers, by Ville Mikael Turjanmaa.
MenuetOS development has focused on fast, simple, efficient implementation. It has a graphical desktop, games, and networking abilities (TCP/IP stack), yet still fits on one 1.44MB floppy disk. It also facilitates easy, full-featured assembly language programming. This stands in marked contrast to the (as of 2007) widespread view that assembly languages are useful mainly for old and embedded systems.
Testing (the GPL'd) MenuetOS in QEMU is easy:
qemu -fda M32-084.IMG -m 384
There's also Menuet 64, written in 64-bit assembly, but that's not open source'd for some strange reason I don't understand. But you can try that one, too (the binary images, that is), using QEMU:
qemu-system-x86_64 -fda M64-059.IMG
One of the single most useful packages when it comes to PDFs in Linux is pdfjam.
From the website:
The installation is easy as always:
apt-get install pdfjam
PDF is not exactly the most easily editable format out there, but these tools can save you lots of time and trouble. Just recently I needed to merge two PDFs into one (and I didn't have any source format of the files). A simple
pdfjoin foo1.pdf foo2.pdf --outfile bar.pdf does the job in a few seconds.
Equally useful when you need to print huge documents is
pdfnup --nup 2x2 foo.pdf, which sticks four PDF pages into one (thus drastically reducing the amount of pages you have to print)...
Update 2006-09-20: As was noted by several people, pdftk is very cool, too. It can do some other things such as split PDFs, encrypt/decrypt them, manipulate metadata and more...

Don't ask me why, but my video iPod has unexpectedly arrived yesterday instead of sometime next week as I was told. But hey, who am I to complain?
No time for blogging, must play with iPod...
