Programming fundamentals

Everytime a programming exercise or project comes up I hear a lot of
my classmates crying out in horror or dismay. I hear them complain
about how hard is or even that it’s impossible to create. And yet I
see a few of us who don’t care how complicated a project is, we just
know that everyhting is doable. I believe the reason for this is that
others still don’t know what we’ve come to realize, you don’t solve a
problem as a whole, you break it into small pieces, and those small
pieces into smaller pieces, until all you have are just a lot of
small, easy to solve problems.
When you’ve come to that point all you
need then is time. Fact is, There’s no programming project that can’t
be reduced into a series of simple arithmetic, true or false
questions, and the separating and combining of strings. The trick of
course is to be able to see the problems as a combination of smaller
pieces, that’s the skill that separates a coding wizard from a
wannabe.

Take my PusoyDos as an example. I didn’t program it all in one get go,
I did it in pieces. First and foremost problem I had to solve was how
to deal th ecards to the players. Eventually I was able to break it
down into just a randomizing function, a few arithmetics, true or
false question and string combination to create the values of the
cards, and a boolean statement to pass it into the designated players.
And I just went on from there.

Programming is actually simple, if you just look at it the right way.

Awwwww. =D

Of course, Jino’s outlook on programming is completely not my fault,
but I hope other people reading this feel encouraged.

ERC pseudo-AI assisted IRC help

March 1, 2004 - Categories: -Uncategorized
  Hmm. That gives me another nifty ERC idea - if we annotate BBDB records with timezones, we should be able to
          greet people good morning/day/evening appropriately. Plus points for greetings in native languages! ;)
  Now that's just insane, really. 
  *augh*
  laugh too
  sacha: I'm sure you'll have it done by tomorrow ;)
  sachac: that could be nice, yes
  ,there is also an evil place without a name -- it does not have emacs
  Added entry to the term "there"
  ,now
  try:  Acknowledgments NowPlaying PostItNow WikiAcknowledgments WikiNow
  arete: Well, I've been thinking of rule-based matching on privmsgs received, with responses suggested in another
          buffer for easy selection with keysequence or mouse... =)
  sachac: good idea
  hehe yeah, saw you mention it the other day
  just one step away from eliza =P
  arete: I'm just thinking of how to do it nicely so that the matches don't take a terribly long time. I suppose
          match-string is my friend. I can build the regexp at the start, match it constantly, then match again based on
          the match string...
  ,df rx
  rx is a Lisp macro in `rx'.
  (rx REGEXP)
  Translate a regular expression REGEXP in sexp form to a regexp string.
  See also `rx-to-string' for how to do such a translation at run-time.
  The following are valid subforms of regular expressions in sexp
  notation.
  STRING ..[Type ,more]
  arete: ... but of course that means I'll be working as a stateless machine for now. Oh well. Actually, no, the
          functions can keep state on their own; I just won't be able to add new keywords without recompiling the regular
          expression, which shouldn't be too hard.
  sachac: I guess the best way for the greeting is some standard text that gets translated at other ercs
  don't forget to weight the chosen responses so you don't have to look through them all each time the same choices
         come up =)
  sachac: use rx-to-string and a variable...
  myrkraverk: Actually, that will hook into my "hi" thing...
  oh, k, then
  myrkraverk: ERC should not only check which of your pals are online, but also which you haven't greeted yet, and
          people who aren't pals but who have greated you specifically. =)
  I haven't written said "hi" thing yet, though.
  Err.
  Greeted.
  Grrr.
  myrkraverk: Ideally, ERC should compile a list of people to say Hi to, and hi them all on one line, appending a
          generic ", world" at the end or something like that. =)
  myrkraverk: An extension to BBDB could have custom greetings for hi. For example, I greet some people in other
          languages.
  sachac: you have too many ppl to say hi to ;)
  myrkraverk: It's a proof of concept! ;)
  myrkraverk: If you tie that in with the funky timezone thing, that would be, well, pretty funky.
  btw, can erc let me know when someone is online?
  sacha: don't' forget the automated reply to a greeting =)
  myrkraverk: However, the timezone thing could be done without the funky hi thing...
  hmm
  arete: My proposed system wouldn't be entirely automated. It would suggest responses, but it would allow the
          user to actually change them or select a different response from the buffer.
  howdy sachac
  arete: I'm thinking of a circular queue of 5 to 10 (of course, configurable) possible replies.
  zeDek: howdy zeDek
  Well, that's an easy way around it - just echo the greeting... ;)
 * sachac is the resident bot-in-training. ;)
  lol
  sachac: btw, I have a photo now on orkut (like you care :P )
  *chuckle*
  zeDek: did you find time to send me the new color-theme ? :)
  Lukhas, ok wait
  thanks
  arete: I'm interested in this because I stay on a few help channels. My hippie-expansion from BBDB is pretty
          useful for expanding factoids, but (a) I don't want to have to remember what to expand, and (b) I want to be
          able to deal with questions I might not have paid attention to. ;)
 * zeDek was migrating old gnusfr.org and emacsfr.org
  lukhas -> free point fr
  myrkraverk: I'll check that out when I get around to starting up a graphical browser...
  did you find hosting room ?
  sacha: now there is a more productive use of it =)
  I can never remember what keyword fsbot wants
  delYsid: Hmmm, that should be interesting.
  arete: The human still filters the automatic responses, of course. =)
  I use it in chess-ics for a very complicated re (760 chars)
  arete: And automatic responses can be of the form :  already...
  arete: Naturally, if we allow functions and strings as canned responses, then we can even have a state machine.
  yumm, pseudo-AI assisted irc help
  Lukhas,
  arete: Yeah, something like that. 
  Lukhas, done
  arete: Worth hacking on in my spare time, I think.

Java and OO Best Practices

March 3, 2004 - Categories: -Uncategorized

This is in no way a comprehensive discussion on Java and OO Best
Practices. This is a subset of the knowledge we pass around with each
other. All of this is subject to programmer opinion and there’s a lot
more that needs to be learned.

bad practices (“code smells”)

- duplicate code
Have you ever copy-pasted your code?
Follow the “Once and Only Once” rrule.

- accessible fields

Tight coupling, corruptible, inflexible.
Should have accessors and mutators.
Problems with threading.

- large class

A class should only be doing one thing. Follow the “one
responsibility rule.”

- large method
- using magic literals
- unnecessary class/instance variables

If it’s only used in one method, make it local

- Initializing strings with “new”
- Using floats and doubles for currency calculations
- Returning null
- Subclassing for functionality
- Muffling exceptions
- Unexceptional exceptions
- Excessive use of switches
- Middle man: methods that just delegate to other classes. Case of over-design.

good practices
- validate your parameters
- abstract or final
- create local copies to prevent corruption (hmm… good for multithreading, but heck slow)
- String, string buffer
- favor immutability (now, there’s a thought…)

software engineering best practices

Note to self: should have webcam-based project that tracks red laser pointer.

Open house

March 6, 2004 - Categories: -Uncategorized

To formally welcome you to the DISCS open house is the Dean of SOSE, Dr. Fabian Dayrit.

Objective:

- Recruitment activity, been offered a slot and we’d like to encourage you to come to the Ateneo
- Also for us to introduce what the Ateneo stands for, what the Ateneo is. If you come to Ateneo, you will be spending four or five years here and it will probably determine your future.
- Core curriculum, major curriculum

Education is a partnership. Student, faculty, school. Education is not a one-way affair. Students play a big role in the quality of the education. V. important that you know what Ateneo is. Best school really depends on the student.

Why come to the Ateneo to study Science and Engineering?

“Lux in Domino.” Pursuit of knowledge and wisdom which is inspired by service to God’s work.

Magis (more): service and excellence

One of the oldest Jesuit institutions of higher learning in Asia.

The core curriculum is the primary instrument of formation, through
which the Ateneo spirit of excellence and service are articulated and
passed on to students.

All S&E students take courses in history, social science,
literature, philosophy and theology, in addition to their major
courses.

Importance: Basic education ~ 10-11 years. Among the shortest in the
world. Students enter at 15 or 16, 17 is old. Very young students. The
core curriculum helps form students through the formative teenage
years. Even in that sense, very important role.

Science not just for its sake.

Major curriculum trains students in the fundamentals of the field, the
state-of-the-art, as well as its applied areas. Interdisciplinary
dialogue is encouraged among the science and engineering disciplines,
as well as with the humanities, social sciences and management.

All of our students get accepted into the schools of their choice, if
they choose graduate school. No problem with the science part of our
curriculum. If you look through the catalog, many of our degree
programs are interdisciplinary. MIS is between CS and Management.
Computational sciences. BS Management of Applied Chemistry. Skills
not just found in one discipline.

Our Faculty

Leaders in their wown field, excellence in teaching and research,
mentorship. Short list of awardees. About 5 in the school, the
highest in any one school. Also awards that are more professionally
oriented.

Our students

Leaders in their own field. 11.5% scholars in Loyola School, 47% in
SSE. CHED requires 1% scholarship. Leaders in their own field.

SOSE departments: Bio, Chem, ECE, ES, DISCS, Math, Physics

Interdisciplinary areas

Information technology, environment, materials science and
engineering, biochemistry and molecular biology, science and
mathematics education

S&E education at the Ateneo

- Excellent faculty and staff
- Solid foundation in fundamentals
- Exposure to applied areas
- Student-centered learning
- Research and hands-on experience
- Personal mentoring for the faculty

March 6, 2004 - Categories: -Uncategorized

So I was playing Mystery of Time and Space in class, thanks to the
students who pointed me to it. I did remember to tell students they
could interrupt me any time, and I did answer a few CS21B questions
while playing.

Apparently, they were surprised at the ease at which I solved the
puzzles. Hey, I’m into adventure games and lateral thinking puzzles -
makes sense.

plan and BBDB

March 7, 2004 - Categories: emacs

I want to collect all of my notes about people into wiki pages about
them so that I can easily see timestamps. I will also need to
cross-reference. In the meantime, I can keep this information in my
daily notes.

Issues:

- Privacy? I’d like some things public and some things encrypted.
- planner-bbdb-remember dependencies. I think I’ll need the condition-case idiom.

Techie dinner

March 7, 2004 - Categories: linux

Last night, I had dinner with William Yu,
Miguel Paraz, and
Jijo Sevilla. Jijo organized the
get-together.

While waiting for Migs and William, Jijo and I chatted about his new
IT consultancy. He described the fat client Debian-based system he had
in mind, with computers automatically drawing updated packages from a
central repository. Jijo wanted to know what I thought of the project.

I told him to check out FAI, a Debian package for doing
fully-automated installs. I also told him about configure packages to
help propagate configurations. He could set up a network-booting
system, with CD backups in case the network went down. He was
delighted – these tidbits would make his job a whole lot easier.

He asked me because he knew I watched the debian-user list and so
might know of similar problems and solutions.

Here’s how I keep an idea of all Debian packages in my head:

- I spent some time reading the package summaries of all the packages

available in Debian’s unstable+experimental archives. This was part
of choosing new packages to install, so it was fun.

- I use aptitude’s “forget” command to mark all of those packages as old.

- Whenever I update my package lists, aptitude marks packages I

haven’t seen as “new.”

- I review those and then use “forget” again to mark all of them as old.

That’s how I keep track of all existing packages available for i386. I
still use apt-cache search and aptitude’s search functions
extensively, but at least I know what to look for.

I also watch debian-devel for Intent to Package (ITP) announcements. I
used to keep track of freshmeat.net, but found it too far from my
normal workload, and not useful enough.

Looks like that’s my Geek Power – I’m a search engine. ;)

LONG SHOT

March 7, 2004 - Categories: -Uncategorized

Company bonding, so we’re out for billiards this afternoon. I spot an
easy shot, although long – ricochet off the walls and pocket the last
two balls. My gal claps when she sees how I’ve lined it up. The boss
watches me intently, twisting his cue stick. I think of the rent, and
carefully miss.

Jester: A test coverage tool that introduces bugs

March 9, 2004 - Categories: -Uncategorized

http://jester.sourceforge.net/

“Why just think your tests are good when you can know for sure?
Sometimes Jester tells me my tests are airtight, but sometimes the
changes it finds come as a bolt out of the blue. Highly recommended.”
Kent Beck

Jester finds code that is not covered by tests. Jester makes some
change to your code, runs your tests, and if the tests pass Jester
displays a message saying what it changed. Jester includes a script
for generating web pages that show the changes made that did not
cause the tests to fail.

Should emacs-wiki links be easily editable?

March 10, 2004 - Categories: emacs

With the recent addition of `emacs-wiki-link-escape’ and
`emacs-wiki-link-unescape’, links are now unescaped before displaying.
This makes them uneditable. People probably shouldn’t be editing the
links manually as this can screw up planner links (among others), but
I should provide an easy way to edit the link at point. I have a
function in my emacs-wiki-config.el to do that. I’ll probably bind to
C-c C-e, which makes sense.

Planner tasks from notes

March 10, 2004 - Categories: emacs

Planner tasks from notes should update the notes page that they link
to while maintaining the special links. This means that
planner-jump-to-linked-task needs to be smarter.

Let us look at case 1: Link to plan page note

The plan page has a date link, no anchor. The date page has a plan
link with an anchor. Example:

 #A1  _ Foo (2004.03.11)
 #A1  _ Foo ([[SomePage#1][SomePage]])

Problem! The plan page does not contain enough information to
reconstruct the link if necessary. I can’t think of a neat way to fix
this yet. Can anyone?

Relax, Everything Is Deeply Intertwingled

March 11, 2004 - Categories: emacs

http://ifindkarma.typepad.com/relax/

I’m also interested in personal information management. Fisher sounds
really cool, although naturally I’d need it to be open-source and
Emacsable. I find that planner _is_ already changing my life, changing
my patterns for doing things. I like how it helps me manage my mail,
keep my blog, search the bits and pieces I remembered.

Browsing through Adam Rifkin’s entries, I think that he’s someone I
should learn from.

Incidentally, I have 115,729,742 bytes in my mail.misc now. That’s
mostly personal mail. I have 3,095,920 bytes in my ~/notebook/plans .
That’s my blog entries, schedules and tasks. =)

E-Mail from Adam Rifkin

Response to Adam Rifkin; personal information management

March 11, 2004 - Categories: emacs

I like your technical and personal and I think I can learn much from you. =)

In particular, I am interested in personal information management. I
maintain PlannerMode, an organizer for Emacs. I use it to blog
(http://sacha.free.net.ph). My Emacs setup allows me to hit a
keystroke to remember anything from almost anywhere. It automatically
captures context and allows me to jump back to that. The source pages
are on my hard disk, so I regularly regexp-search through them. This
lets me use my blog to remember things.

People are surprised to find my task list, schedule and notes online.
They ask me why I don’t mind the lack of privacy. I find that
publishing my notes works to my advantage. Almost every other day,
someone writes in with a bit of info or a tip that’ll help me finish a
task. Plus, publishing my task list shames me into procrastinating
less.

I’d like to work on making it easier to retrieve information from my
blog and my e-mail. The Remembrance Agent
(http://rhodes.www.media.mit.edu/people/rhodes/RA/) is great for
indexing mail and a few other resources. It brings up entries that are
relevant to the words around your cursor. You’ve probably run across
the software and related papers—if not, check it out!

I’m also interested in XML. I hacked in RSS export for my blog. It
autocategorizes my posts based on a regular expression. A minor
modification will let me define arbitrary rules.

Answering JP, someone else on the technical groupblog:

I like the idea of RSS syndication because I want to aggregate and
search blogs without having to scrape HTML. With either a simple
regexp search or search-engine-like relevance ranking, finding
information in other people’s knowledgebases becomes much easier. If I
download feeds, I can even search offline. Push on creation is useful,
but people still need a way to get to old posts.

TLA semi-tutorial

March 11, 2004 - Categories: emacs

I used to really like CVS, but I found it hard to make my CVS stuff
available to other people. I didn’t want to have to rely on an
external CVS server. For a while I used vc’s double-backend support to
do RCS locally and CVS on savannah, but I found it hard to switch back
and forth.

Damien Elmes introduced me to tla. I really
like the way I can publish my repository online, over HTTP – no need
for special server support. I also liked how I could easily pull in
patches from other people. It was a bit hard to learn, but I
eventually got a repository up and running. I like how the metadata is
kept locally, so I can develop even when I’m disconnected, and yet I
can synchronize it with my webserver so that other people can pull
updates.

Are you sure you don’t want to give it a try? =) Here’s how to do it.

More about diagrams in Linux

March 12, 2004 - Categories: -Uncategorized

From Allan Espinosa:

xfig is a great clipart diagramming editor the “wysiwyg” component does
not look too good when zoomed out. for example, a polygon created does
not look like a “polygon” but just jagged lines. But when zoomed in the
polygon can be seen. The rendering to postscript was also exceptionally
good with anti-aliasing. what are you guys using to edit *.fig files?
will compilation with xaw3d widgets fix this or the xaw3d libraries are
just eyecandy? the screenshots from the xfig.org site looks nicely
rendered but i thinked they zoomed it enough not to show all the ugly
aliasing and poor rendering

xfig is good for quick and dirty diagrams but if i want to have good
looking pictures with subscripts and formulas I use GNU pic/ dpic with
m4 macros. the circuit_macros package from ctan.org is one of the best
schematic drawing packages out there. The output looks like text-book
quality schematics!

Searching for all entries related to a person

March 15, 2004 - Categories: -Uncategorized

How would I search for all entries related to a particular person? A
BBDB search that resolved URLs would get the explicit bbdb links
perfectly, but what about the links automatically derived from
annotations? I could search for all links and then parse out the name
derived from the BBDB if the link is of the form _____ from/to ____ .

The more general question is:

How do you extract entities (persons / resources) from semi-structured
text? I’m working with hyperlinked entries, so I can assume that:

- any e-mail is associated with a person (I hope)
- websites will frequently be rooted off another person’s namespace
- the contact database is populated by people
- names will tend to be non-dictionary, capitalized words

I’ll start out by getting explicit, consistent links recognized. Then
explicit, inconsistent links. Then unlinked names (woohoo).

easily navigate through all of the data in my personal store. Zoe
(http://zoe.nu/) looks interesting, but it’s outside the way I work.

I’m interested in the kind of massively hyperlinked personal
information management that you describe in TODL. Text-based
navigation through an automatically-extracted graph would be
fantastic.

As for implicit linking, word vectors are often used to find similar
documents. The Remembrance Agent developed at MIT displays a running
list of N items relevant to the words around point. Time and location
may also cue document retrieval.

It doesn’t have to stop at personal information like TODOs or notes.
Why not generate source code as well? With literate programming tools
in the style implemented by Leo (http://leo.sourceforge.net). Leo is a
tree-based organizer. Cloned nodes allow you to have arbitrary graphs
and output is customizable. This is close to what you envisioned with
TODL, although it seems to be a primarily graphical tool.

Your description of TODL mentioned the KM system developed by P. Clark
and B. Porter, but it seems to require explicitly encoded facts and
queries. I would like to do research on implicit linking and querying
in semi-structured text. As a fresh BS graduate with some research
experience (one published paper in a conference about distributed
computing, a few programming competitions) and no formal background in
text analysis, I really need an adviser interested in this field.
Would you know anyone interested in this?

New Muse keyword: :osuffix

March 18, 2004 - Categories: -Uncategorized

If you derive one file from another produced by Muse (ex: PDF from
LaTeX from Muse), then use :suffix to specify the extension of
the intermediate file (.tex in this example) and :osuffix to specify
the output. See muse-derive-style for more details.

Oooh, subvocalization

March 18, 2004 - Categories: -Uncategorized

From Slashdot:

alex_guy_CA writes “Yahoo News has a story about technology that
comes close to reading thoughts not yet spoken, by analyzing nerve
commands to the throat. ‘A person using the subvocal system thinks
of phrases and talks to himself so quietly it cannot be heard, but
the tongue and vocal cords do receive speech signals from the
brain,’ said developer Chuck Jorgensen, of NASA’s Ames Research
Center, Moffett Field, California. Jorgensen’s team found that
sensors under the chin and one each side of the Adam’s apple pick
up the brain’s commands to the speech organs, allowing the
subauditory, or ‘silent speech’ to be captured. The story indicates
the method could be useful on space missions or other difficult
working conditions.”

Problem with footnote.el and auctex

March 21, 2004 - Categories: emacs

From Rainer Volz:

In case anybody has the same problem, I (probably) found the source and a
workaround.

The error “Symbol’s function definition is void: TeX-add-style-hook” is caused
by the footnote-mode, which in turn is loaded by muse-mode, as a default minor
mode in “Muse/Muse Mode/Muse Mode Hook”.

Turning footnote-mode off lets me enter muse-mode (and planner-mode) without
the error. Since I rarely use footnotes I can live without footnote-mode.

If you can’t: several messages found on the net seem to indicate that the real
source of the problem is a path/duplicate file problem between the normal
texinfo.el and a texinfo.el supplied by Auctex. footnote-mode tries to load
the normal texinfo.el but gets the Auctex version, which then tries to run the
function “TeX-add-style-hook”. A solution could be to change the load-path for
Emacs libraries or to deinstall Auctex.

Hope that helps,
Raine

cal-desk-calendar support for planner-diary.el

Hi all,

I patched what I hope is the most recent version of planner-diary.el
from tla to optionally utilize cal-desk-calendar. cal-desk-calendar
is an add-on for diary-mode which displays the day’s events in a neat
“desk calendar” like way. I wanted to be able to have this pulled
into my day planner pages instead of just a list of the scheduled
event. To do this, I added a variable ‘planner-diary-use-cal-desk-calendar’,
which when set to non-nil will cause cal-desk-calendar to be used. I
patched planner-diary-get-diary-entries to handle this.

She glanced at the clock impatiently, trying to ignore the giggles and
peals of laughter that erupted from the classrooms next to K-1B. 8:35.
Where were her kids? By this time, Annie would be gazing out the
window, daydreaming of castles and princes. Mike’d be fidgeting at the
back, unable to keep still. Laurie would be dutifully working on the
exercise for the day. She wrung her hands. Where were they?
Kindergarten students were almost never late. The school bus service
dropped them off at 8:15 everyday. One or two might be truant, but an
entire class?

She surveyed the empty chairs with growing concern. Locking the
classroom door behind her, she hurried to the principal’s office. “My
students—”, she began, but the look of horror on the principal’s face
robbed her of breath. She turned to the television set that transfixed
him and her world blew away with the smoke billowing from the
yellow crushed metal that once protected her angels.

Stanford: Stream data manager

March 23, 2004 - Categories: -Uncategorized

http://www-db.stanford.edu/stream/index.html

In applications such as network monitoring, telecommunications data
management, web personalization, manufacturing, sensor networks, and
others, data takes the form of continuous data streams rather than
finite stored data sets, and clients require long-running continuous
queries as opposed to one-time queries. Traditional database systems
and data processing algorithms are ill-equipped to handle complex and
numerous continuous queries over data streams, and many aspects of
data management and processing need to be reconsidered in their
presence. In the STREAM project, we are reinvestigating data
management and query processing in the presence of multiple,
continuous, rapid, time-varying data streams. We are attacking
problems ranging from basic theory results to algorithms to
implementing a comprehensive prototype data stream management system.

CS planning meeting

March 24, 2004 - Categories: emacs

Dr. Sarmenta: research. Thinking of research programs. On the positive
side, CS197 this year went particularly well. Lot of good projects.
One of the things that helped out: more groups (groups of two), also,
started early. August, start writing proposals. One of the things that
I think it’s a good sign of is that we can do a lot in terms of
research. Our students are pretty capable. The upcoming two batches
are also pretty good. We can look forward to being able to tap them.
The other thing that helped this year— Jon and I tried to help focus
everybody. Those who had research ideas, we encouraged. We also had a
pool of projects in mind and some people took them. There was still a
significant part of the batch that did database/web stuff, but we
tried to spread it out some more. ~1/3. Those ones we screened also.
Pretty good batch. Start even earlier, maybe summer. If we have ideas
already, it would be nice. For example, for the wireless, we had lots
of ideas. Students also have their own ideas, and sometimes they just
needed encouragement. I’d like us to have personal research agendas.
We should all be working on at least one research project. Think of it
as part of our teaching job. Common interests? Real output.

(Information retrieval from semi-structured text; open source
development; social network analysis and the Semantic Web. Named
entity extraction from hypertext.)

In preparation for the planner meeting, Eric:

- Compile a list of publications
- Active research projects we’re doing right now
- Publications: start with the PAASCU list
- Opportunities for people to publish (goal), deadlines
- Resources

map of where we are. If we can list projects we want to work on this
coming year…

Doc Mana: Can we move defenses earlier so that we can hold a
conference?

That would be a good idea.

(Time-ordered information streams; continuous implicit queries)

After we have this, maybe we can have research groups.
How MIT worked: each professor has his own project, and there’s an
umbrella group. There’s a theme.

Pretend you’re a student and you’re looking for a project to do. What
would you like to do?

Junior faculty point from Dr. Rodrigo. Research output is one of the
criteria for permanency.

CS side. Harder science side. Stuff that’s more technical rather than

Bandwidth minimization, etc. You get to play around with a PHP 4M
cluster…

Hey, we have a Simputer! I will borrow one!

Also, the digital video thing Darla did. Jeff volunteered.

Symbian phones.

On to the important stuff — planning logistics.

Subic is traffic, but we’ll go for White Rock anyway.

Can we prepare a project proposal?

Remembering

March 25, 2004 - Categories: emacs

A friend and I were thinking of papers to submit to the Loyola Schools
Review. I joked, “What could I write about PlannerMode?” It’s an
organizer that I happen to really like, but which I don’t think I can
get other teachers to adopt (Emacs’ll scare the heck out of them!).

I thought about why I liked PlannerMode. Planner as a TODO manager
isn’t particularly special. Although I can assign tasks to categories
and so see a breakdown of what projects are taking up my time,
Evolution and Microsoft Outlook provide more powerful task support. In
other task managers, you can e-mail tasks, assign multiple categories
and fill in all sorts of metadata. You can even synchronize your tasks
with devices like a phone or PDA. So why use Planner?

I realized that integration into my way of life and automatic context
clues are what really make planner tasks worth it for me. I don’t have
to switch to another application to create a task. I can just hit a
keyboard shortcut. Planner uses a minibuffer to get the task
description. My windows are not rearranged in any way, and I can look
at the data that’s relevant to a task. Not only that, tasks
automatically pick up context clues, like whom I’m talking to on IRC
or the file I’m editing at the moment. This cuts down on the explicit
context I need to include and makes it easier for me to bring up the
task again.

As a scheduler, PlannerMode is also not particularly distinguished.
Sure, it can display my ~/diary, but for that matter so can M-x diary.
Evolution and Outlook can give me a more graphical view of my time,
sync with my PDA, and coordinate my schedule with other people. Those
applications support detailed schedule entries with powerful cyclic
options. On the other hand, PlannerMode gives me a personal, plain
text view and (at least the way I use it) requires me to edit a
separate file to add new appointments. However, it does have one
advantage – my schedule is always loaded. I used to use Outlook on
Windows, but having my schedule in a separate application meant that I
actually looked at it very rarely, as I had turned off reminders
because they got annoying.

PlannerMode‘s notes, however, are what really convinced me. I can hit
a keyboard shortcut from anywhere and type my notes into a buffer
which automatically keeps context information. After typing the note,
I can then categorize it. I think that the critical thing here is that
interruptions—fleeting thoughts—don’t break my flow. I can just pop
up a remember buffer, stow that thought away somewhere, and go back to
it whenever I want. In contrast, creating a note in Outlook means
switching out of my application, making a couple of keystrokes, typing
the note in, and then switching back. The context switches make it
hard to keep track of where I am and what I’m supposed to remember.
Not only that, I need to enter context by hand. Even though I can
color my notes and reorganize them in Outlook, I find the context
switch too expensive. I used to keep notes in other knowledge
management tools as well. Some applications allowed me to
drag-and-drop links into the current note, and that was cool. But
that required a manual action, and those applications didn’t feel
integrated into my way of working.

I guess that’s why I like PlannerMode. Unlike other organizers which
don’t know anything about the applications I use, PlannerMode tries
its best to integrate into the way I work, and it’s easy to extend.
Fortunately I do almost all my work in Emacs, so I can think of my
organizer as integrated into my e-mail client, Internet Relay Chat
client, web browser, file editor and even games. It automatically
picks up context clues from these applications and allows me to easily
jump back to relevant files. It doesn’t distract me. It allows me to
key in data and then it gets out of my way.

The processing that happens in the background (publish to RSS and PHP
for me) is a bonus, and publishing my task list and notes online has
greatly helped me. It gives other people a way to see what I’m working
on and what I’ve planned for the future. Occasionally people write in
with additional resources and helpful tips.

This made me wonder how to integrate it with more applications and
make it available to more people. Yes, even the vi users and the
non-Linux/Un*x geeks. Here are some of the thoughts that went through
my head.

- What if everyone could have the equivalent of M-x remember even if

they’re not using Emacs?

- What if we could capture context from any application?

- What if remembered thoughts could have multiple categories and

could be reorganized later?

- What if we could use statistical methods to suggest categories for

text and find related items?

- What if whenever you interacted with the system, related notes would

show up? When you open a file, browse a page or look at a contact, a
sidebar could allow you to quickly jump to related topics.

- What if you could visualize your remembered thoughts to see how

they cluster around certain topics?

- What if you could perform powerful search operations on

remembered thoughts?

- What if it could pick up even more context clues, tying together

different applications? For example, if you do your e-mail in Eudora
but keep your main contact information in Outlook, wouldn’t it be
nice if remembering from an e-mail also linked in the business card
from Outlook?

- What if we could select some of these remembered thoughts and

publish them in different formats, automatically or manually?

- What if we could share our stream of remembered thoughts with other

people?

- What if computers could generate remembered thoughts as well, and

we could select which ones we’d like to include in our streams?

The more I think about it, the more I feel that this is worth studying
further. If we develop this idea, other people can benefit from it -
not just those who incidentally use it in the course of using
PlannerMode! John Wiegley was onto something good here, and it’d be a
shame to keep it only within a niche community. I’d like to make it
easy for my mom to use this. =)

For my MS degree, I want to develop a framework for remembering
thoughts from different applications. This means separating the
front-end, the back-end, and the context gathering functions. Right
now, everything is within Emacs. I’d like to split it up so that
people using windowing environments like GNOME or KDE can get a nice
dialog box if they want and people using other editors on the console
can use their favorite editor to add notes. I’d like to split the
backend up so that people can remember to SQL databases, plain text
files, mail—anything and everything. I’d like to split the context
gathering up so that application developers can easily hook into the
system.

For my PhD, I want to look into managing all of this information.
How do I find relevant documents now that I’ll be capturing
vastly more information? How can I make browsing my personal data
store easier? How does it change my work style? Can I think of
interacting with my computer—working on e-mail, writing documents,
etc.—as interacting with a stream of remembered thoughts? Can it be
my primary interface? If we shared our remembered thoughts with other
people, how would that affect the way we work?
