Doodles (by )

Ok I know I promised ages ago to show you all some of my art work but I havent got round to the scanning etc... I have some shoddy pics here I took with the camera of my doodles in a little A5 note book I have - these really are light doodles though so dont expect anything good!.

snake men

This was me trying out ideas for webcomics - but found something too similair since 🙁

dragon

Ok I was thinking of gothulu and the like when I drew this - this all started cos a gothic horror/dark sci fi and fantisy inprint is looking for pictures.

snake

More of the same.

club woman

This one is based on a dream I had - the style is me mucking about with ideas of how to illistrate something for Al.

shaggy man

Erm.. I was bored?

horn

Ok this one again was working on styles for Als thing.

demon

In desperation with the fact that I appear not to be able to draw anymore I went hunting for a book - becuase of the specific project I'm working on I was excited to find a book called Anatomy for Fantasy Artists - I copied this from just inside the front cover - 1st time I've done a copy like this in 4yrs :/

angry man

I was attempting to manga/cartoonise a photo here.

barbas duaghter

This is another one from the book - its supposed to be the barber's daughter - the book makes a big point on how difficult it is too draw children and how right they are - I was copying and have managed too draw her older sister who is blatently a teenager!

heads

Floatling heads - I was just trying slightly different styles.

demond

Yes well it was late ok.

dragon head

I was crossing over styles with this - just doodling really as they all are!

fat face

Again just trying out different styles.

bleed

Ok I was trying to make someone look ill - and the pen slipped but its a nose bleed ok!

Whitelists and Blacklists (by )

In my previous post, I spoke of technologies that prevent [email spoofing](E-mail spoofing) by reliably tying the mail server sending a message to a domain, or checking that the message is from who it claims to be from.

These measures alone can reduce spam - in the short term - because, right now, lots of spam is spoofed. But as these technologies spread, spammers will set up lots and lots of domains, put valid SPF and CSV records in them, and start spamming.

CSV vs SPF vs DomainKeys (by )

There are a number of technologies vying to protect us from spam, by providing channels for legitimate senders of email to prove that any given message comes from them, thus allowing them to build a reputation (and get whitelisted) while spammers' domains and/or mailserver IPs get bad reputations, and they can't spoof messages to steal the good reputations of others.

This is entirely separate to tools like SpamAssassin, which try to analyse emails once they've arrived, and allow a recipient to judge their spaminess regardless of who they've come from.

It's also entirely separate from things like HashCash, which work by letting senders attach a mathematical proof to their message that shows they've invested a second or so of computer time, thus distinguishing them from people who send thousands of messages per second.

Missing Kitten! (by )

Well we called for H last night and she didnt come in - perhapse shes asleep in our bedroom then - we thought. This morning ni sign of the normal playful hungry kitten so out side plate of food in hand calling - nothing - no flash of black and white fur as there should have been.

We began to get really worried - then I heared very faint mewing - I searched the coal 'bunker' where it sounded like it was coming from - Perhapse she was stuck in the cattle grid or something - no - still the mewing. I turned and lo - there she was mewing at me from the window of the little garage 🙁

Poor thing - I went in there early yesturday morning - Al says he hasn't been in there - all I can hope is that maybe Babara thought it would be a good idea to let her in there whilst we where out (as if its daytime we let the kittens roam outside). But unlikely meaning the poor thing was in there for ages but I'm sure we fed her dinner :/

Still she's back and safe and her sister kept mewing at us last night - in hindsight she was trying to get us to rescue H - oh well.

On the topic of cats - Minni keeps making a disturbing clanking of jaw and salavating sounds and motions as she watches the birds feeding at our bird table - her tail goes flick flick flick!

Designing for unit tests (by )

I'm writing a unit test for a bit of code that connects to a server. The bit of code has parameters - hostname, username, password, and details of what to fetch from the server.

The thing is, the infrastructure it's placed in expects it to store the password in encrypted form. It has to use a separate component that contains a hidden master key to decrypt the password when it's required, and to encrypt a new password given to it.

Also, since the application will be fetching lots of different things from different servers, it quite reasonably has a 'host' abstraction that can be referred to by lots of data collection modules; it keeps a central list of hosts, and my component is passed a Host object.

But when writing a unit test for my component, this is a pain. The way the central list of hosts and the crypto component are accessed involves going through a 'session' object that also has lots of things like listening sockets, database connections, and much other complexity afoot.
