Re: New long range router! :-)

2008-03-19 Thread Ed Montgomery
I'm wondering if the OLPC has become aware of a new
long-range wi-fi router, reported in MIT review.

Apparently, gives 6Mps for at least 60 miles!
Could be very useful in some remote areas.

Re: Alternative power/recharging source?

2008-02-22 Thread Ed Montgomery
Came across this rather amazing item the other day,
and instantly thought this might be a very, very
useful power/recharging mechanism for the XO...

A lamp powered by gravity producing 40 watts over 4
hours...using gravity! :-) (Consider the XO using
about 2 watts...)
Not affected by weather/season/time of day (e.g.
solar/wind) or behaviour (animal/cow) or location,
etc.  An unlimited power source available anywhere
anytime!

Could this mechanism (which apparently is more durable
than the LEDs in the lamp!) be modified to power
and/or recharge the XO batteries, etc.?

A preliminary article about the gravity lamp can be
found here (from Virginia Tech):

Re: see quoted below, etc.

Ah, kids these days...young whippersnappers...;-)

How about doing some work on DSLinux? ;-)
(i.e. linux for the Nintendo DS...about 4 megs ram to
work with, etc.)

Now THERE'S a challenge! :-)  You should be whipping
bits around at light speed with 256 megs
available...:-)

I maintain a linux distro based on uclibc with
strictly static
linking, no shared libs at all. It's primary dev home
has 128MB and
a Transmeta Crusoe at 660MHz. It's using 2.1GB of it's
4GB disk, but
that includes the complete sources for the 355
packages it includes,
ranging up to biggies like a few different kernels,
gcc, and the
like. And shared libs save space, too.

Re: passwords, etc.

2008-01-12 Thread Ed Montgomery
Regarding the note about the 'paranoid' password
filtering, etc.

Changing passwords as root does not involve any of the
'too short', 'too similar', etc. problems mentioned. 
Root, being god-like, can change any password to
anything.  For regular users, it is an education about
password security! :-)  (Since, in my experience, they
always ask me 'why?' ;-)).  However, if it really,
really bothers you, then why not simply remove the
filtering from the source code, recompile, and call
it, oh, I don't know, perhaps something like 'spasswd'
for 'simple password', and then you can customize it,
avoid problems mentioned, etc.

I.e., Use the source, Luke!

Re: Protecting children

2008-01-06 Thread Ed Montgomery
Glad you brought up this point.  I have been somewhat
concerned about the child security of this project
(but I just may not know).  As a computer teacher for
many years, I have seen several cases of students who
have been negatively affected by their contacts and
activities on the net.  I'd be happy to be involved in
a site for teachers (and/or developers, etc.) who are
interested in child security issues, etc.  

For example, you (or any member of the public) can
verify my teaching record on this Canadian government
website:
http://www.oct.ca/PublicRegister/memberDetails.aspx?memberID=164928
(Feel free to contact me or oct.ca to verify, etc.)

I.e., you really do need to know whom you are dealing
with.
I assume the U.S. has a similar system?

In any case, I'll be happy to volunteer to look after
a  
 teacher/developer whatever website in child security
issues, etc.

Sincerely,
Ed Montgomery


  In fact, I think we need a Social Networking Web
 site specifically for
  the children, protected from adults who might want
 to interfere or
  exploit children. And a site for teachers,
 parents, and other
  interested parties. Would anybody here like to
 help create such sites?
 
 I think we (I) need a network of teachers that can
 respond to software 
 developer questions.

Re: Printing et al.

2008-01-03 Thread Ed Montgomery
Having been a computer teacher for several years, I
set up a network printer for those teachers who
requested it, (but it was a CONSTANT hassle, from
paper jam problems, to misconfiguration, toner
cartridges, etc.  I got around the problem by handing
off the problems to   windows techs, which left me to
the paradise of just running a linux lab ;-)).

In the meantime, I went paperless...:-)
My students were required to place all of their work
on websites/web pages.  Then it was always available,
never lost, shown to other students, parents,
teachers, etc. at any time! ;-)  (And optionally,
could be placed on the worldwide web, as opposed to
just a school network/server, if one really wanted to
'display' work, etc.) ;-)

A much better solution, I found. :-)
Heartily recommended, as opposed to the archaic method
of printing out reams of paper, multiplied by millions
of students/teachers/parents, at considerable cost to
the environment, etc.

Re: languages et al.

2007-11-24 Thread Ed Montgomery
Fascinating, as Spock would say...:-)

I taught for two years in a small town called Haenam,
in South Korea, and two years in Japan on Jet program
(currently just wandering around Japan :-)), and
likewise studied a few languages in university, etc.,
having always been fascinated by them. (Kanji holds a
particular fascination for me, for some unknown
reason.)  I can communicate well enough, I suppose in
three languages, (but of course, language learning is
a lifelong process, eh? (eh=famous Canadian emphatic
particle :-))

The really scary people are like James Platt (who,
unfortunately is no longer with us), on the OED team,
who was famously quoted as saying:

consulted linguistic advisers, such as James Platt
who knew scores of languages and once famously
declared that the first twelve tongues were always the
most difficult, but having mastered them, the
following hundred should not pose too much of a
problem.

Yikes! :-)  Quoted from here, by the way, for those
interested:
http://www.amazon.com/gp/reader/0198607024/ref=sib_dp_pt/105-9251581-449#reader-link

Anyways, I have placed at the following link, a first
attempt at a first draft (?!!), a French translation
of a first draft of an English manual of the XO.  I'd
appreciate corrections, etc., as well as an image of
the XO without the English phrases on it. (Yes, I
could use the gimp and wipe out and add the French,
etc. but it would be easier, more elegant and save
time if I could just have the original photo.)  Also,
I have no idea what is going on with page 10. 
Suggestions, recommendations, etc. are welcome.

http://languageknowledge.googlepages.com/xodocv2-fr5.pdf

Ed, you and I are rather similar in our language and
keyboard usage. I
have studied several languages, and have lived in
Korea (Peace Corps)
and Japan (Buddhist training). I use Ubuntu with the
Gnome keyboard
switcher and SCIM. I have worked on documents in
English, Chinese,
Japanese, and Korean together, and on single-language
documents in
French, German, Russian, Ukrainian, Armenian,
Georgian, Greek,
Yiddish, and other languages. Not that I speak all of
those languages,
but I can type and proofread to some extent, handle
character set
conversions, and a little of this and that besides.

French accents on an English International keyboard
are added with the
Compose key. So

Compose-`-e gives ?
Compose-,-c gives ?

and so on. The KDE and Gnome keyboard switchers let
the user set the
Compose key to be right ALT (AltGr), right CTL, either
Win key, the
Menu key, or Caps Lock. AltGr is the default for the
XO, but I use
Menu on Ubuntu.

I'll add a version of this to the Wiki page on
Keyboards.

No?  Well, then M$ doesn't fit the spec.  Too bad. 
Bye-bye. (And sorry for the rant everyone.  This is a

Re: Language lurker! :-)

2007-10-27 Thread Ed Montgomery

Language lurker here...

For those who might not be familiar with it, may I
mention having a look at the children's paint program,
Tuxpaint at tuxpaint.org.  They have been developing
the program for several years, and it has been
translated into over 70 languages at the moment, using
the .pot .po system.  One might find some
help/suggestions, etc. there:
http://tuxpaint.org/features/

 ET In response to Xavier Alvarez' request on 10/25
 for
 ET translators and coordinators, I decided to get
 off the
 ET sidelines and take a look at OLPC's new
 Pootle-based L10N
 ET infrastructure.
 ET
 ET Here are a few things I noticed which I think
 will be of
 ET general interest and concern:
 ET
 ET (0) CASING/NAMING OF PO FILES PROBLEM:
 
 The 'rule' is quite simple (but not necessarily as
 intuitive as 
 may be expected): given that we are bundling several
 d.l.o 
 projects into pootle-projects, we need to ensure (or
 at least 
 minimize the possibility) of having 2 POT files with
 the same 
 name.
 
 Solution? We prefix whatever filename used for the
 POT in d.l.o 
 with the name of its project...
 
 journal-activity.Journal.po
 --dlo-project-.filename
 
 Thus, any 'inconsistencies' are really product of
 other 
 inconsistencies... they just happen to be more
 evident (and ugly) 
 within Pootle.
 
 ET
 ET   (Upper/Lower) Casing of names of po files
 is
 ET inconsistent: For example, in Core there is
 ET journal-activity.Journal.po with upper case
 J for
 ET the 2nd occurrence of Journal but then why
 isn't
 ET write.write.po written write.Write.po? 
 ET
 ET   This is a small point, but consistent and
 inuitive
 ET naming of these PO files will help everyone. Or
 am I just
 ET failing to understand or intuit what the pattern
 is supposed
 ET to be here?
 ET
 ET (1)  INCONSISTENT NUMBER OF MSGIDs ACROSS
 DIFFERENT
 ET LANGUAGES: 
 
 Yes and no.
 
 The numbers shown in the statistics do not represent
 quantity of 
 MSGIDs but WORDS in the file. So I presume that for
 untranslated 
 strings it takes the MSGID words, and for translated
 strings, the 
 MSGSTR. Thus two languages with all things
 translated and upto 
 date, may still show different numbers (although
 conceptually 
 they are the same). BTW, it does show the number of
 strings in 
 other 'statistic levels'.
 
 Yes, I was quite baffled too... translators are more
 worried about 
 the word-count than 'lines of code'... ;)
 
 In http://solar.laptop.org:5080/projects/xo_core/
 Language  Trans.  Fuzzy   Untrans. Total
 Portuguese (Brazil)   162 42% 4   1%  213 56% 379
 Spanish   219 62% 0   0%  132 
 37% 351
 
 While in each language+project
 [pt_BR]   8 files, 162/379 words (42%) translated
 [118/247 strings]
 [es]  8 files, 219/351 words (62%) translated
 [157/234 strings]
 
 Note that even Still, there's a difference with the
 number of 
 strings... see below.
 
 
 ET
 ETThe other day when I looked at
 write.write.po for
 ET French, there were only 10 messages in the

 ET see that there are 36 messages which looks a lot
 closer to
