Reverse tunneling SSH ... manual extract
-L [bind_address:]port:host:hostport
Specifies that the given port on the local (client) host is to be
forwarded to the given host and port on the remote side. This
works by allocating a socket to listen to port on the local side,
optionally bound to the specified bind_address. Whenever a con‐
nection is made to this port, the connection is forwarded over
the secure channel, and a connection is made to host port
hostport from the remote machine. Port forwardings can also be
specified in the configuration file. IPv6 addresses can be spec‐
ified with an alternative syntax:
[bind_address/]port/host/hostport or by enclosing the address in
square brackets. Only the superuser can forward privileged
ports. By default, the local port is bound in accordance with
the GatewayPorts setting. However, an explicit bind_address may
be used to bind the connection to a specific address. The
bind_address of “localhost” indicates that the listening port be
bound for local use only, while an empty address or ‘*’ indicates
that the port should be available from all interfaces.

Sherlock Holmes on Knowledge
Sherlock Holmes closed his eyes and placed his elbows upon the arms of his chair, with his finger-tips together. “The ideal reasoner,” he remarked, “would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it. As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after. We have not yet grasped the results which the reason alone can attain to. Problems may be solved in the study which have baffled all those who have sought a solution by the aid of their senses. To carry the art, however, to its highest pitch, it is necessary that the reasoner should be able to utilise all the facts which have come to his knowledge; and this in itself implies, as you will readily see, a possession of all knowledge, which, even in these days of free education and encyclopaedias, is a somewhat rare accomplishment. It is not so impossible, however, that a man should possess all knowledge which is likely to be useful to him in his work, and this I have endeavoured in my case to do. If I remember rightly, you on one occasion, in the early days of our friendship, defined my limits in a very precise fashion.”
“Yes,” I answered, laughing. “It was a singular document. Philosophy, astronomy, and politics were marked at zero, I remember. Botany variable, geology profound as regards the mud-stains from any region within fifty miles of town, chemistry eccentric, anatomy unsystematic, sensational literature and crime records unique, violin-player, boxer, swordsman, lawyer, and self-poisoner by cocaine and tobacco. Those, I think, were the main points of my analysis.”
Holmes grinned at the last item. “Well,” he said, “I say now, as I said then, that a man should keep his little brain-attic stocked with all the furniture that he is likely to use, and the rest he can put away in the lumber-room of his library, where he can get it if he wants it. Now, for such a case as the one which has been submitted to us to-night, we need certainly to muster all our resources. Kindly hand me down the letter K of the American Encyclopaedia which stands upon the shelf beside you. Thank you. Now let us consider the situation and see what may be deduced from it.
Excerpt from 'The Five Orange Pips'... partial quote in Pro Git book piqued my interest. Will read the book @ some stage ... it's PD and available on Project Gutenberg

Vodafone’s DNS settings
I'm having problems surfing the internet? How do I change the DNS settings?
I'm having problems surfing the internet? How do I change the DNS settings?
If you're having occasional browsing issues, you can specify 'domain name servers' on your computer to see if this fixes the problem.
Vodafone’s DNS settings are:
• Preferred/Primary DNS: 203.109.129.67
• Alternate/Secondary DNS: 203.109.129.68
How to change these settings if you're using broadband:
• Go to Control Panel > Network Connections and select your local network
• Click Properties, then select Internet Protocol (TCP/IP)
• Click Properties
• You will see 'Use the following DNS server addresses' and enter the desired DNS server(s) in the space(s) provided
• Click apply and then try browsing the internet again

Vodafone Broadband settings
What are the basic settings for my Vodafone broadband?
These settings are the same for all our Vodafone fixed line broadband products.
Login: username (your username for broadband is your Vodafone fixed line email address eg. username@vodafone.co.nz)
Password: your password (lower case)
PPP: PPP over ATM (RFC2364) VCMUX encapsulation
VPI - 0
VCI - 100
Every ADSL modem or router has a slightly different way of entering in these basic settings. Simply look at the instruction manual that was supplied with your ADSL modem or router for full details on how to enter these settings correctly.Some brands of router ask for the DNS settings. If required these are
Preferred DNS server: 203.109.129.67
Alternate DNS server: 203.109.129.68
If you're switching to Vodafone broadband from another provider, we've put together a handy guide of all the settings you need to change.

Debugging Embedded
Al Williams (Dr. Dobbs') on Embedded Debugging and attitudes:

"I've hired a lot of programmers over the years. Most were average, but you always remember the highs and the lows, I suppose. Ironically, one of the guys on the lower end of the scale did a fantastic interview."
Most were average? Amazing! :)

Beagle Board first impressions
Serial connector pins marked incorrectly - doesn't match pin #1 indicator on header plug -- ?Odd/even pin rows rolled over/mislabelled?
There doesn't seem to be a canonical way to initially start up the board for checkout - what's initially loaded?
How do I tell whether someone has changed/bricked it?
How do I recover it if it has been bricked?

Erik Naggum's Contempt Page
For the last hour or so I've been enjoying (and posting) nuggets of quotations from Erik Naggum's Contempt Page... Happy Snacking! :)
How applicable are the techniques of sound programming?
The programmer should not ask how applicable the techniques of sound programming are, he should create a world in which they are applicable: it is his only way of delivering a high-quality design.
Edsger W. Dijkstra:
Answers to questions from students of Software Engineering (EWD 1305)
Edsger W. Dijkstra:
Answers to questions from students of Software Engineering (EWD 1305)
Mastering Complexity or Not
"The computer, by virtue of its fantastic speed, seems to be the first [technology] to provide us with an environment where highly hierarchical artefacts are both possible and necessary. This challenge, viz. the confrontation with the programming task, is so unique that this novel experience can teach us a lot about ourselves. It should deepen our understanding of the processes of design and creation, it should give us better control over the task of organizing our thoughts. If it did not do so, to my taste we should not deserve the computer at all!"

Teachers don't have time or B/W to learn new stuff all the time
Friday night sessions after school with cups of tea or something stronger :)
Water neuron with drinking straws (!)
Fabiana from University
brain study
Tilt / holes in straws etc.
happens in real brain - pathways degrade, neurons break and die...
discussion in class after playing with the neurons outside in the sun (water play)
Teachers can't be expected to know everything anymore
Kids need to learn how to learn and to teach each other also
KiwiFoo Robert??? - Peter Hall ? teacher
- whose focus is figuring out ways to get kids to cooperate (vs. individual and performance-oriented system)
interest.co.nz Bernard Hickey (doom and gloom?)
economic principles in the classroom - mutual currency system in class
exchange of values
5 minute units of time
accrue, spend
excited email - kid approach could she spend / give it away to some other student who needed it more
saving / value / charity etc.
use/lose - decaying value over time
alternative to interest
demurrage - e.g. grain etc deteriorating over time
tradeable/not
Honesty, transparency, respect as basis of the classroom
?response to Friday night sessions - initial nervousness - not knowing what to expect
tips - how to convince? parent! - automatic entry :)
(this would work with Rangi for this year for me)
e.g. robotics Mindstorms
Peter Hall believes CS should be in core school syllabus
Computer Science Unplugged (book, Canterbury University)
Dance routine by logic
leading ego - teacher feels they need to know it all and teach it
Take time to show teachers things and explain, answer questions
e.g. didn't know computer was internet-capable
Cool tips etc. sites
Throw straw men
show up
stacking books on lib shelves coz nobody shows up
10pm parents coming in the next day
type up kids stories as prep
Mum works @ primary school
don't get it
start with basics
build trust
educampnz
Wiki page
similar format to BarCamp
out west? Sumerfield?
Tauranga art gallery
Wiki - kids - interpretations
sessions on MediaWiki - only some will show interest; fewer will actually do anything.
Find time - recognize value - feel comfortable with the change it represents
Classroom blog
videos of reading the stories etc.
[privacy issues?]
other teachers see and emulate
kids doing their own thing
parents happy in general if they see immediate value
AUP addendum etc.
Moodle partner - Brenda

Sugar project - Sugar On a Stick
(Sugar CRM?)
OS and apps run from a stick
persistent and stays with the child
Sat 11am Windsor Parnell active community
testing Sugar on laptops etc.
looking @ ways of getting schools involved
IT specialist tends to be either youngest staff members or last out of Teachers' College
Google groups
MLE reference group - Managed Learning Environments
OSS -- don't want to pay MS fees anymore
some resistant - stick with MS
others embrace OSS etc. - more open to help?
Otumoetai Intermediate - principal switched on (trialling WiFi access points)
Beer @ 11am is good
Mojo MOQ is 100
cheaper than an Eee
a school (unnamed) is looking @ getting them for class sets
Ubuntu login looks just like windows - trialled on kids - didn't notice they weren't using Windoze :)
WikiEducator - q.v.
lesson plans - IP of the teacher - not collaborative traditionally
MIT OpenCourseWare

Could This be the Answer? - 1Password
http://agilewebsolutions.com/products/1Password
If so, I think I forgot the question...
...along with my password (again ... :( )
The problem with using multiple machines and/or browsers, like I do, is that if you once forget one of your many (different, right? ;-) ) passwords for online services, you start to chase your tail trying to re-synchronize the remembered passwords in the browser cookies and/or other magic.

Scheme and Common LISP on JVM
Some interesting discoveries lately...
Kawa is Scheme on JVM (so is SISC) - a GNU official project.
Runs on Sun and various other JVM's.
Armed Bear Common LISP (ABCL) is CL on JVM
Clojure is new and a bit different -- and sounds very impressive indeed from the presentation(s) at http://clojure.blip.tv
Designed to interoperate easily with Java and other languages on the JVM platform.
The designer (Rich Hickey) has removed dependencies on concrete implementations... e.g. abstracting cons's to first and rest.
seq replaces lists as an abstraction.
It's closer to CL than Scheme (Rich says so).
Looks very promising.
