Must find a way to clean mouse point.
Ah, yes, the wireless card. =) I am a very lucky girl. My parents got
me a wireless card for my Christmas gift (in addition to my beautiful
subnotebook, of course). One of the things I really like about my
parents is that they won’t actually wait until Christmas to give it to
me, since I can very well use it before then. =) I have clueful
Got my wireless card working. There was a bit of confusion about eth0
and eth1 – turned out to be my fault. Once I had gotten my dhclient
all sorted out (I was mistakenly calling it from intuitively, and that
turned out to be a Bad Thing), it Just Worked. For reference, I’ve
got a Linksys WPC-11 Instant Wireless card. It’s supposed to be a
Prism2, so has limited functionality but can act as a wireless access
point with the hostap tools. Coverage in Faura is not bad, but I
haven’t checked other areas for decent signal. Should improve if
Dr. Sarmenta manages to get Microsoft to agree to blanket the campus
with wireless access points.
Speaking of Dr. Sarmenta… He was in a meeting earlier, so we didn’t
have ThesisProject class. I want to change advisors. ;)
Back to Microsoft. I really, really hope they push through with the wireless thing. I don’t understand why Microsoft isn’t very actively courting us. C’mon, if I were an evil empire and I wanted to ensure my hold on the future generations, I’d get them while they were young. I’d give freebies, training, cool gadgets, lots of publicity… Microsoft’s a large company with plenty of budget to spare. We just won an international competition – you think they’d take advantage of that wonderful PR opportunity. I suppose their marketing is losing their edge. ;) Of course this is all just personal opinion, since our school obviously believes in Microsoft enough to go for the Academic Alliance and that .NET stuff, but still…
If you think about it, many of our classes are too vendor-centric. Take Contemporary Databases (translation: Oracle), or Enterprise Java Programming (guess), or even Intro to C++, which was actually pretty okay if not fairly boring, and had a sliver of MFC tacked on at the end but didn’t cover other toolkits). On the plus side, we do actually have Systems Programming, which is Unix-based thanks to the strong push of people like William Yu, Sir Marco and Doc Mana if I’m not mistaken. w00t!
(Update 2003.09.24: Come to think of it, we’re remarkably not vendor-centric – at least the classe I’ve taken.)
Anyway, I really should be going to bed now. My roommate has borrowed my alarm clock again – it’s apparently the loudest in the dorm… =) Hopefully I’ll remember to wake up tomorrow. Good night!
Hello, everyone! I’m Sacha Chua, and I’m here to talk about embedded
system design from the developer’s point of view.
What _is_ embedded computing, anyway? It helps to define it in
contrast to personal computers, which we’re all familiar with.
Personal computers are intended for general use. They can run a wide
range of applications – games, business apps, that sort of thing.
Embedded systems, on the other hand, are typically designed for a
single purpose. Think of a calculator, for example, or the logic in
vending machines. (Of course, some embedded systems are becoming more
general now, like personal digital assistants a).
On PCs, you can usually assume that someone
Although crashes and data loss seem to be part of our everyday
computing experience, people expect embedded systems to be reliable.
Imagine an embedded system that crashes! What if your phone crashed
and had to be rebooted all the time? People expect features,
reliability, and all for a low price.
One of the things about embedded development is that the process is a
little bit longer. It’s not the usual edit, compile, run cycle. It’s
edit, compile, burn to flash, run.
And of course if you go into embedded development, you’ll probably
have to deal with different architectures. For example, you’ll learn
about the quirks of conditional ARM.
I’m not really sure where to begin demonstrating what I’ve been
working on. Unlike the other groups who are creating something new
and easy to explain, I’ve been spending the last few months exploring
a different way of life. My contribution to the computer science body
of knowledge isn’t some killer application or breakthrough theory, but
rather experiments, documentation and incremental improvements.
My project is about wearable computing. I aim to show that it can be
done inexpensively, using only off-the-shelf equipment and free
software. To that end, I have been gradually adapting Emacs to
wearable computing needs. Most of what I am demonstrating is not my
code, but the use of it is uncommon even in the Emacs and Emacspeak
communities, and so my contributions have mostly been in the form of
documentation and patches. I have also become the official maintainer
of planner.el, a text-based organizer for Emacs.
Since I’ve based my project off Emacspeak, a lot of things were
instantly accessible. For example, I can easily check the time and
date by pressing C-e t. Emacspeak also allows me to work with
practically all modules in Emacs. Because this foundation is already
quite good, I decided to focus on documenting its setup, demonstrating
its usability and writing or improving upon Emacs features.
I have been using this to organize my notes, although in class I tend
to turn off sound and use the keyboard in order to keep up with the
teacher. School notes are organized by day.
Ateneo library books
Beautiful documentation =)
get a serial to USB adapter so that I can use my phone again.
solve APM kernel problems
get wireless to work reliably, probably via cantenna
I really hope the remember timestamp works now.
