Yesterday’s CS party

April 4, 2003 - Categories: -Uncategorized

Yesterday I had a thanksgiving party for the computer science faculty
and staff. People who went: Dr. Vergara, Dr. Manalastas, Sir Olpoc, Sir Mike,
Sir Maguyon, Ate Lisa, Ate Marivi, Reagan, Sir Mark, Ate Nanette, and
Maan. We played Trivial Pursuit for a short while, but found the
questions too America-centric. Taboo! was a lot of fun. Here’s an excerpt:

Sir Maguyon (? Who was it?): Doc Mana is a… ?
People: Pervert! Sex maniac!
(Turns out the word was “sexist”.)

Then we had grilled steak, salmon and sausages, with portabello
mushrooms and vegetarian pizza for Doc Mana.

It was lots of fun.

Also, got invited to the faculty R&R this 2003.04.14 and 2003.04.15. Practically
required to bring games along.

Hacking Society

April 4, 2003 - Categories: -Uncategorized

On the compsci mailing list, Migz Paraz mentions the
Hacking Society, a pretty cool
idea.

I’d love a real-life space like this. Currently, I get this sort of
stimulation in irc.freenode.net#emacs, which has a high concentration
of – what else? – Emacs geeks who speak little LISP snippets like
it was their native language.

It would be nice to have this happen in real-life; a space where we
can pair-program on anything that comes along. All we really need is a
space with computers (or bring your own!), a common time to meet, and
a common desire to learn something new and hack on something cool.

I’m all for it.

This paper is about mandatory laptop use in the classroom, but since
our labs are one-computer-one-student, the insights are useful. Here
were the uses they observed:

- posting instructional material online
- animating and demonstrating concepts
- collaborative learning exercises
- instant feedback
- automatic program execution and visualization
- evaluation and testing
- communication

The instant feedback thing looks particularly useful, and I will certainly try to write an online system for that – or adapt http://www.moodle.org, which greatly impressed me when I last checked it.

Catastrophix updates — cat

April 8, 2003 - Categories: cat

Catastrophix the kitten is alive and well, although somewhat
fishy-smelling (we’ve been feeding her solid kitten food). She still
hasn’t figured out the litter box or the water dish, but she makes up
for it with quite an appetite.

Some confusion about her age. I’ll go with the vet’s guess placing her
at around a month old. My sister contends that she’s far younger. At
any rate, Catastrophix can walk around (albeit unsteadily), purr
(quite delightfully), and snuggle (rather contentedly).

It’s been hard to type with one hand, but it’s worth it for that
little furball.

UP thesis related to text summarization — research

April 12, 2003 - Categories: research

From 2003.03.28:

Automated Newspaper Article Summarizer

Description: Limited to online World News text articles only, this
summarizer utilizes the algorithms presented by R. Barzilay and M.
Elhadad in their paper Using Lexical Chains for Text Summarization
(1997). The techniques and methods they primarily used are Text
Segmentation, Lexical Chains Computation and Sentence Selection and
Extraction. The summarizer also uses the WordNet Lexical Database as its
knowledgebase for word sense disambiguation and a Part-of-Speech Tagging
Algorithm for the selection of candidate words from the input text. The
algorithms used are based on shallow Linguistic Analysis Approach, which
doesn’t require a full semantic interpretation of the texts to produce
its summary.

The Wonderful World of Emacs – planner.el — emacs, planner

April 14, 2003 - Categories: emacs

Migs, the one who wrote in recently about non-working Year2003,
Year2002 and Year2001 links, has this to ask:

I’m very curious as to how you get so much done with a
console based (?) text editor. Like do you have sort of summary view
of your calendar, tasks, etc in emacs? Maybe you can post a few
screenshots of what you look at everyday. Personally, I’d be lost
without an app like Evolution or Korganizer. I can’t imagine how you
manage all that with emacs.

Migs, that is precisely it. =) planner.el is an Emacs module that
gives me a summary view of my tasks, schedule, and notes inside Emacs
(which incidentally has a nice graphical interface, too). Together
with emacs-wiki.el, it lets me easily manage my website. Another
ultra-handy thing is M-x remember from remember.el, which pops up a
buffer asking me what I want to remember and stores a note in my daily
planner page. For example, this is one such note created by
remember.el. A patch contributed by Thomas Gehrlein allows easy
navigation of planner pages – simply select dates from M-x calendar.

Personally, I prefer this text-file-based system to Evolution or
Korganizer. I remember dropping down to M-x grep to quickly search for
something in my daily planner files. I can backup my data files in a
.tar.gz. I can perform diffs and version control (although I haven’t
gotten around to doing so yet! =) ). I can even run it in
conjunction with the Remembrance Agent.

My tasks and notes can be linked to my address book through BBDB
integration with Planner, and I’ve modified the BBDB url support to
take advantage of certain fields in my database. For example, typing
Sacha Chua results in the
following link: Sacha Chua. Locally, this brings up the address book
record that matches that regular expression. On the Web, it is
transformed into a URL following these rules of preference: blog, web,
e-mail. That allows me to link to other people and even sites much
more easily than HTML or the usual blogging systems might let me do,
since HTML and http://www.blogger.com still require me to type the
URLs to which I want to link.

Because all of these things run inside GNU Emacs, I can easily
access all of my data. I can embed Emacs LISP code into my planner
files and have them automatically evaluated and displayed. I can
switch to my planner file easily from my IRC chat session or from my
mail. I can hook into built-in Emacs functionality or make use of
modules developed by other people. It’s tons of fun!

And I didn’t even write planner.el. Ubercoder John Wiegley did. I
discovered planner.el around 2001.11.03. I liked it so much I e-mailed
John Wiegley to volunteer tech support and bugfixing for it, and he
suggested that I take over maintaining planner.el
instead. (2002.11.21) Open source is so much fun! =)

To see a sample of the text files I work with, you can check out my
planner directory at http://richip.dhs.org/~sachac/notebook/plans/ .
The published files are listed at
http://richip.dhs.org/~sachac/notebook/wiki/WikiIndex.php.

People interested in duplicating my setup may want to check out my
configuration files. They are all found in my notebook/emacs/
directory. Files of interest are planner-config.el,
emacs-wiki-config.el, and remember-config.el. Please write to me
at sacha@free.net.ph if you have any comments or suggestions, and
don’t hesitate to ask for help in setting up a wonderful personal
information management system in Emacs.

Computer science – is it an exact science? — education

April 14, 2003 - Categories: teaching

On plug@lists.q-linux.com, Ritchie Roi Y. Chua writes:

Computer Science is a science, but not an exact science like physics…

Interestingly enough, computer science is as exact as you can get. =)
Physics? Even grade-schoolers know about experimental errors and the
fact that measurements are never completely exact. Biology is
similarly based on guesswork. In contrast, you know that 3 in
mathematics is exactly that – 3, not 3.000000000001 or
2.99999999999999999. Computers are somewhat less precise due to the
limitations of our hardware, but the theory can be as precise as you
want. Think of Turing machines. Think of algorithms.

One of the things I find pretty darn fascinating about computer
science is that it is far cleaner and more exact than the natural
sciences. Computer science is the work of man.

Employment stress

April 15, 2003 - Categories: work

My mom and I had a somewhat stressful discussion about the vagueness
of my employment. To wit: I know that I am going to teach, but I
don’t know under what terms or even how much I’ll earn. (Whoever goes
into teaching for the money is nuts, but it would help to know how
much rent I can afford!)

I guess what stresses me out is the fact that at 10:37 PM in the
evening, I can’t do anything to improve the situation, and all these
questions are making my department seem so bad. The CS department is
really nice (although a bit disorganized), although yes, I’m somewhat
peeved that they can’t really bend the rules for me. <wry grin>
Case in point: after bugging the finance department for a little over
a month, I’ve just recently been told that faculty housing is going to
be nearly impossible for me to get because I already have housing in
Manila. Makes sense. In fact, I felt somewhat guilty about having
stayed in the dorm for so long, taking up a slot that may have let
someone from the provinces study in Ateneo instead. The main thing
that stresses me out, however, is the possibly firm stance my parents
might have on the necessity of on-campus housing.

My mom seems to be softening a bit – she was offering to help me
search for an apartment or a ‘bedspacing’ arrangement. However, this
didn’t prevent her from checking with another school that was looking
for teachers (an IT school – I want to teach computer science, not
information technology!), which of course completely freaked me out.
I spent the next half hour having a nice good cry with my kitten. I
really, really want to teach in Ateneo because I’m more used to the
school culture and I’ll have a better chance of being allowed enough
latitude to experiment and possibly make a difference. I _hope_ my
parents won’t make me choose another school, but if they express
strong disapproval…

Another source of stress is the vagueness of the terms of my
employment – aforementioned lack of information about such basic
things as salary and job expectations. From the way things have been
going around the department, I’d probably do more than your typical
fresh-grad teacher. Me? Typical? But how does one consider these
atypical things, then? I already do the work gratis, but it would
be… somewhat nice to be appreciated, or… at least meet someone
else who is as into these things as I am.

Maybe I should just set my sights on the Most Outstanding Junior
Teacher award. I’ll need a lot of luck and practice to get that.

My mom basically thinks that they’re taking me for granted. I’m
supposed to be the best in the Philippines, but there’s a very, very
fine line between asserting that I deserve more than this… and being
completely annoying and arrogant.

All I really want to do is teach. And learn. And have fun. And help
other people learn and have fun. Not necessarily in that order.

Mental note: Be much more assertive.

How assertive can I get, anyway? <wry grin> I can’t very well
threaten not to teach in Ateneo, because everyone knows I really want
to do so. I guess the better approach would be, “Wouldn’t that be the
professional thing to do?”

Or something like that.

<sigh>

Update: Okay, now that I’ve gotten my employment jitters out of
the way, I can concentrate on preparing for class. =) I really, really
love our school.

Okay,
planner-el_1.90-1_all.deb
passes lintian checks and builds with debbuild. Yay! Now to figure out what to do next..

Unfortunately there’s a Debian Developer named “sacha”, so I guess I’ll have to settle for sachac if ever…

Tense changed.

April 16, 2003 - Categories: emacs

From now on, planner page stories will be written in past tense
whenever appropriate. Present tense just sounded too weird. Old
planner pages will not be updated to reflect this.

Computer accessibility and wearable computing

April 21, 2003 - Categories: research

Panthera Altaica is into wearable computing because of computer accessibility.
Hmmm. Interesting. From e-mail:

I’m working on a interface that’s is basicaly a suped up CLI based on
Multi User Forth(RPN, stack), Perl(CPAN, moduals) and HTML 4(programs
control the information that is display not how to display the
information). It should allow the quick intery of commands and the
commands should be independant from the UI.

I’m plaining on a Forth and Lisp displays for the stack for the
demostration. I still only have vagist ideas on how to handle the
File system, text, images.

Assistive technology and wearable computing

Moodle.org and LANG

April 22, 2003 - Categories: teaching

Moodle’s postgres7.sql is missing a lang char(5) default
'en'
declaration in prefix_user. This causes user additions to
fail. To fix an already set up database, simply

ALTER TABLE moodle ADD COLUMN lang CHAR(5);
ALTER TABLE moodle ALTER lang SET DEFAULT 'en';

Moodle

Picture should not have an empty string. Fixed by adding $user->picture = -1 .

Teaching was so much fun! — education

April 23, 2003 - Categories: teaching

The spaghetti exercise was a big success, as it underscored real-life
application of algorithmic thinking. Adding two numbers took a fair
amount of time, but was somewhat effective. Note: tomorrow, assign a
beadle, prepare a seat plan, prepare history notes, prepare questions
about piracy, DRM, reliability, industry/academe… =)

ARGH! Left my power cord!

April 23, 2003 - Categories: geek

Silly me. Well, I guess that means I’ll be working on the CS21A
breakdown on the Mac and I’ll be sleeping early tonight. I guess I
should make the most use of it, then. Since my CS21 curriculum review
notes are on the web (they are, aren’t they?), all I have to do is
move the cs21a and cs21b mirrors into my public web hierarchy.

Notes about today — education

April 24, 2003 - Categories: teaching

Quiz took too long. Next time I do an algorithmic thinking quiz, do this in two parts:

- identify input, output and test case(s)
- discuss input, output and test case(s)
- write an algorithm

- discussion next time, because I need to read everyone’s algos in order to identify common errors

Glad to say that students get to seriously work with Linux in Ateneo -
you can thank Horatio Bogbindero and Dr. Manalastas for that! =)

Never underestimate the importance of playing. I play with Emacs all the time,
and I learn something new every day.

(Incidentally, I should also figure out this trackback thing… I wonder if emacs-wiki.el can handle that.)
