Wizzy Digital Courier's mission is to radically drop the cost of Internet access in every aspect, from equipment, to phone rates, to remote access, to the point that most schools in the world can now consider it for their kids.
In most countries the Internet, that is EMAIL and WEB, is not available in schools.
For kids to graduate without an intimate and second nature experience with the Internet leaves them seriously unprepared.
The "Digital Divide" is actually only an economic divide.
We have a novel system of using a USB memory stick to carry Internet content.
When Telkom were given another five years of monopoly seven years ago, I thought it was too long. The Second network operator has been a long time coming, and is not here yet.
In return for a promised rollout of connectivity to rural areas, Telkom were allowed a monopoly of provider interconnect, international connectivity, and wireless (wireless -across property boundaries or a road, not office 802.11B)
Naturally, this artificially inflates Telkom's value, and the anticipated return of a de-regulation stock sale.
To the Government's credit, and ICASA they have acted in the interests of the South African consumer and liberalised the environment before de-regulation.
The problem it is designed to overcome is the high cost of local
telephone calls in a monopoly wireline provider regulatory
environment.
We use cheap-rate overnight phone calls and a UUCP delivery system in
conjunction with a local mailserver and wwwoffle web cache.
UUCP can also be used via a USB memory stick, similar to the DataMule (pdf)
paper referenced on the website. Carrying the memory stick (the Courier)
is identical to one UUCP hop.
I live in South Africa - one of many countries that use
the
GSM mobile standard. Here I have a pay-as-you-go SIM card, meaning that I
am almost anonymous.
Going on a month business trip to Australia - I plan on doing the same thing -
get a pay-as-you-go card, so I take my GSM phone over.
Go to the corner store - "Starter pack please".
"Sorry Sir, we need you to fill out all this information
- Gov regulations, sorry."
"After they verify the information, your SIM card will be turned on"
Every single piece of info was wrong, yet my phone came on the next day.
Cheers, Andy!
Re:How to filter the worm: - BAD ADVICE

The following regular expressions trap this virus dead, no matter what subject line, message body, or filename it uses:
If expression body matches "UEsDBAoAAA*" Move [virus folder]
If expression body matches "TVqQAAMAAA*" Move [virus folder]
As others have said, this is bad advice, because it checks about 2.5 bytes at the beginning of the file.
One thing these virus messages do not have, that regular mails do have, is a Message-ID:
header line - which means that the first receiving MTA (usually sendmail or something
on your inbound mailserver) adds one.
I use exim, and I have admin privileges.
I use this (from the exim mailing list) in the DATA ACL:-
# Deny messages without Message-ID, but allow bounces. deny !senders =: condition = ${if !def:h_Message-ID: {1}} message = RFC2822 says you SHOULD have a Message-ID.\n\ Most messages without it are spam, so your mail has been rejected.
Works great.
If you do not control your MTA, perhaps you can filter by searching four your
MTA's signature within the MessageID: header.
My father flew spitfires during the second world war.
One of the things they had to contend with were barrage balloons - balloons with steel wires
above the cities that planes had to fly around or hit. They devised an
explosive cutter that fitted on the leading edge of the wing, to cut such cables
(in emergency, I think, I do not think one would do it deliberately).
One of the fitters had to test it - he stuck his finger in.
Nothing wrong with that - but I think you need a local webcache to deal with 20 minute ping times..
Seriously, you need to bring your own entertainment, and/or to be able to deal with latency. You will never be coming back. You need to check on post-mission status of folks that have been on the space station for a long time.
That said, you can write software, and contribute to the human species permanent record from Mars with slashdot, commit privileges and a feedback channel.
You will probably have made a more permanent mark than many people living today.
My memory is a little vague, but I do remember some incident where a case was one by a company because one of the programmers triggered an easter egg in the defendant's code, which blatantly showed that the defendant _had_ been stealing code. Can someone who has better recollection than me refresh my memory?
I also remember that one. Bit o' googling comes up with
This article -
the meat of which is (spelling left intact):-
Now, in fact (and I've verified this) if you type BOOT/SYS.WHO (notice
that password WHO...) at a TRS-DOS 2.3 prompt, hold down the right
combination of keys (2,4,6?) and press return, it'll clear the screen, go
into 32 column mode, and display a copyright notice. This copyright notice
is not obviously stored in the remaining blocks of BOOT/SYS - from memory
the bytes are XORed with the position in the message and with the
keyboard data lines before being displayed.
The above is all fact, and I've verifyied it myself.
Now for the rumour, which I can't veryify. Note to lawyers - I'm passing
this on as I heard it, and I'm not saying if it is true or not.
One version of TRS-DOS wasn't written by Tandy, but by a 3rd party and
licensed to Tandy. Tandy got fed up with paying the license fee and came
out with a new version which they claimed was entirely re-written. Said
3rd party claimed that parts of it were taken from his code.
Said 3rd party asked for a TRS-80 Model 1 and a new TRS-DOS disk to prove
his case (I don't know if it ever went to court). He went through the
above routine, and it displayed _his_ copyright notice. Tandy had copyied
the boot granule and hadn't realised there was an easter egg in it.
Later versions kept the easter egg, but with a Tandy message.
But, and here is the beef, it should be obvious to anyone that there must be a interface change in the short term future of search. A textbox is a very limited input to express a complex search. Using regexps and regexp-like operators is not enough.
Have to say that the command line and regexps (is there any other way to do a regexp?) have done me proud the last 20 years, and probably the next. A fill-in form ? Maybe easier for you than me.
We also do internet access for those who cannot afford it. Bullocks would work..
We use a USB memory stick as a physical carrier for internet data - Email and (cached) web access. Check it out at wizzy.org.za - based out of South Africa, but with an open-source CD download at the site above.
Personally, I have STRIP - a free Palm app that remembers all my passwords - and anyone
else's I need to know:-)
The main rule for me is make them long. A long passphrase is as easy to remember as a
short one, and is not subject to the standard attacks. I use the Compuserve
algorithm - two common words joind with punctuation. New website asks for a password ?
Mailman bugging you again ? Join a couple of prominent words on the site with
punctuation.
I did come across, and use, the unrememberable password - these are great.
A string of numbers/letters, and a repeat in a slightly different order.
Takes some work to remember, but you can sing it across a room, and they have
to type it right away, and they won't remember it:-)
When I was at Brunel University on a post-grad course,
we built chips for Associative
Processing (pdf)> or Google HTML
that inherently used Ternary logic. The main chip that we built was an
Associative memory
chip, that stored binary data, but was addressed by searching for data.
There were no address lines. It was a wide field - 40 bits,(this was late 70's)
and you presented a search term as Ternary data on the input lines.
Each bit was 1,0,X - where X meant "don't care". You could add one field column to another,
without any of the data exiting the chip.
Say you wanted to add an 8 bit field - bits 0-7, to another, bits 8-15, and store the
result in a 9 bit field, 16-24.
Search as follows (CC Field is Carry):-
Bits: C 1 1 1 1 1 1 1 Bits: C 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 Find: X X X X X X X X X X X X X X X X X X # All rows Writ: 0 0 X X X X X X X X X X X X X X X X # Clear output Find: X X X X X X X X X 0 X X X X X X X 1 # 0+1=1 Writ: 0 1 X X X X X X X X X X X X X X X X # write 1 Find: X X X X X X X X X 1 X X X X X X X 0 # 1+0=1 Writ: 0 1 X X X X X X X X X X X X X X X X # write 1 Find: X X X X X X X X X 1 X X X X X X X 1 # 1+1=0 carry 1 Writ: 1 0 X X X X X X X X X X X X X X X X # write 0 carry 1
Whew. You have added the LSBs of the fields together, in 6 operations. There
are 8 more to go. However, you have done it for the entire array
which might be thousands of records.
So there is a fixed processing time for parallel operations on all the data.
We still had to use two input lines to represent the Ternary value, but, remember,
no address lines needed.
Content Addressable memory chips are also used for lookaside Cache memory
in CPUs today.

If I want to point other people to it, I show them Google Groups.
If I want to search it, I use Google Groups.
I loved DejaNews Author profiles.
I do not like the idea of new 'groups' that are not accessible via NNTP. I think the continuity from pre-HTTP til now is important.
Kudos to SAIX for maintaining a good NNTP server for all customers - a big job.
Cheers, Andy!

There was nothing wrong with them putting that malloc.c, ancient or not, in the code. Code doesn't grow old.
Perhaps things got sloppy or it was never noticed because someone had previously removed copyright notices?
Yes - there was a problem over copyright notices.

A severely bad idea.
A lot of systems I maintain have NFS-mounted home dirs - /home/ is on another machine.
When the sh*t hits the fan, I need to be able to log in - as root. The last thing I need is root's home dir inaccessible.
There are decades of wisdom behind Unix, most of which I have no desire to re-learn. Not broke ? Don't fix.
