Setting up mercurial init.d web serving

cd /usr/lib/cgi-bin
cp /usr/share/doc/mercurial-common/examples/hgweb.cgi .
chown www-data:www-data hgweb.cgi
chmod u+x hgweb.cgi

comment the last two lines of hgweb.cgi and add the following:
#application = hgweb("/data/hg/test", "repository name")
#wsgicgi.launch(application)
from mercurial.hgweb.hgweb_mod import hgweb
from mercurial.hgweb.hgwebdir_mod import hgwebdir
from mercurial.hgweb.request import wsgiapplication

def make_web_app():
    return hgwebdir("/usr/lib/cgi-bin/hgweb.config")

application = wsgiapplication(make_web_app)
wsgicgi.launch(application)

create: hgweb.config
[collections]
/data/hg = /data/hg

Add the following to: /etc/apache2/sites-enabled/000-default
ScriptAlias /hg "/usr/lib/cgi-bin/hgweb.cgi"

(Also includes resources for digest as well as allowing no pass on clone/pull, but restricting push.

7.4.1. Restrict to known users

This configuration restricts access to a known set of users as defined in the /home/user/hg/hgusers password file:

    AuthType Basic
    AuthName "Mercurial repositories"
    AuthUserFile /home/user/hg/hgusers
    Require valid-user

Since the AuthType directive is set to Basic, passwords are communicated as plain text, and it is therefore recommended that this only be used with a server configured for HTTPS. See the Apache SSL documentation for more information

http://mercurial.selenic.com/wiki/FAQ

4.22. How can I store my HTTP login once and for all ?

You can specify the usename and password in the URL like:

http://user:password@mydomain.org
Then add a new entry in the paths section of your hgrc file. With Mercurial 1.3 you can also add an auth section to your hgrc file:

[auth]
example.prefix = https://hg.example.net/
example.username = foo
example.password = bar

SSL Configuration

http://www.tc.umn.edu/~brams006/selfsign.html

http://www.tc.umn.edu/~brams006/selfsign_ubuntu.html

cd /opt/openssl
openssl genrsa -des3 -out server.key 4096
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
# Make a copy of the server key that does not require the password
openssl rsa -in server.key -out server.key.insecure
mv server.key server.key.secure
mv server.key.insecure server.key

# server.crt: The self-signed server certificate.
# server.csr: Server certificate signing request.
# server.key: The private server key, does not require a password when starting Apache.
# server.key.secure: The private server key, it does require a password when starting Apache. 

cp server.key /etc/apache2/ssl
cp server.crt /etc/apache2/ssl
a2enmod ssl
a2ensite  default-ssl

Then edit the default-ssl.conf to change the web root-- for instance /var/www-ssl. Also modify the keys to use your custom server.key and server.crt

#!/bin/sh

S=`date +%s` && rsync -azv --exclude=.Trash --exclude=Library/Caches --link-dest=/data/macbook/current /Users/matt/ 192.168.1.88:/data/macbook/$S && ssh 192.168.1.88 "rm /data/macbook/current && ln -fs /data/macbook/$S /data/macbook/current"

better than this on below because it allows for failure recovery...

Processing/Arduino Serial Communication (LED Dimmer)

http://www.arduino.cc/en/Tutorial/Dimmer

I made some modifications to the sample to play around with it.

I have a couple of problems.

1) I cannot figure out how to send a byte (numeric) through a tty emulator -- the emulator picks up the ascii values for each character.  It would be nice to be able to just send a numeric if possible.
2) You can only have one thing at a time connected to the tty port.  Makes sense, I just didn't think about it when I tried to use the Arduino serial monitor while my Processing application was attached.
3) The 64 bit Linux compatibility with processing serialrxtx (fixed in another post.)

Arduino CODE

/*
  Dimmer
 
 Demonstrates the sending data from the computer to the Arduino board,
 in this case to control the brightness of an LED.  The data is sent
 in individual bytes, each of which ranges from 0 to 255.  Arduino
 reads these bytes and uses them to set the brightness of the LED.
 
 The circuit:
 LED attached from digital pin 9 to ground.
 Serial connection to Processing, Max/MSP, or another serial application

const int ledPin = 9;      // the pin that the LED is attached to
const int  ledFailPin = 13;
int ctr = 0;

void setup()
{
  // initialize the serial communication:
  Serial.begin(9600);
  // initialize the ledPin as an output:
  pinMode(ledPin, OUTPUT);
  pinMode(ledFailPin, OUTPUT);
}

void loop() {
  byte brightness;

  // check if data has been sent from the computer:
  if (Serial.available()) {

    digitalWrite(ledFailPin, LOW);
    // read the most recent byte (which will be from 0 to 255):
    brightness = Serial.read();
   
    // set the brightness of the LED:
    analogWrite(ledPin, brightness);
   
   char s[4];
