turn the router off, or get one of those timer switches for $5 or put this in /etc/crontab

wendroidon Becoming a "Spamassasin"

I integrated and adminsiter a postfix / sa / clamd / courier system for about 10,000 domains (6 identical blades with local storage for the queues and Global File System GFS once they've been accepted).

SA gets about 95% accuracy on our system even at 5.0

I can also recommend enabling SPF and DKIM see http://www.openspf.org/ Wave bye bye to emails pretending to be sent from yourself to yourself or those annoying "your settings have changed, open this zip file" mails.

wendroidon Hilary Mason: How to Replace Yourself with a Very Small Shell Script

It all got a bit messy by that point, low cashflow, mortgages to be paid etc. The risk takers were using their house as collateral and decided to go safe. It was an amicable parting.

wendroidon Hilary Mason: How to Replace Yourself with a Very Small Shell Script

When I worked for a "we'll all work from home" company we used to use IRC as our office. Saying hello to everyone every morning got a bit repetitive so I scripted some good mornings and when people arrived it got triggered to say hello for me.

Eventually though, our sales guy twigged that he was being fooled (as he saw it) and got annoyed about it. The tech side thought it was a cool script but to appease the guy I turned it off.

The irony is that he fucked the company by finding cheaper subcontractors to make more money for himself, a phenomena I've encountered quite a few times now.

wendroidon Obviously, HP Thinks We Are Stupid

Same here with an HP4000+ from eBay. Full duplex, network, two full ream bins, $150. I expected it to die pretty quick but two years later (and 1000s of pages) the spare toner is still on the shelf.

wendroidon Obviously, HP Thinks We Are Stupid

The only problem I had was the usual - leave it for 6 weeks without printing and it gums up a bit.

I've also had some feed problems where it dumps ink into the printer.

The guys I share an office with got one and didn't read the instructions properly and we stood their (me laughing) as the ink unloaded into the thing.

But when it's all working you get 6+ months of reliable printing.

And for the price of an inkjet, a spare one is cheap, though I'm lucky - my local retailer is 5 mins away by foot and when my dried up I just went and got another one - the dried up one is under my desk waiting for me to clean it!

wendroidon Obviously, HP Thinks We Are Stupid

1) buy inkjet printer

2) install continuous ink system

3) ???

4) reduce the baseline

wendroidon And, Why Didn't Dijkstra Like Lisp?

It's just that your eyes are closed, these are just about equivalent (same no of () anyway) :

    i.hate(parentheses).split().doyou()
 or
 
    (doyou (split (i.hate parentheses)))

"GOTO Considered Harmful" Considered Harmful

http://www.ecn.purdue.edu/ParaMount/papers/acm_may87.pdf

You use GOTO every time you turn on the computer, though JMP is the mnemonic instead.

wendroidon And, Why Didn't Dijkstra Like Lisp?

I should also say that I have experience working with Manchester cpus (AVR microcontrollers) where the code is fixed when you flash it and you cannot jmp into RAM. Of course one then writes an interpreter instead :)

wendroidon And, Why Didn't Dijkstra Like Lisp?

Well, you know what I mean re: the last bit, it's not just Lisp that can modify code at runtime.

As for C, it's not just the fault of pointers. You just can't shellcode something that doesn't execute data.

Like I say, we'd just have a different class of problems, so it's not a panacea.

wendroidon And, Why Didn't Dijkstra Like Lisp?

I think it's a bit disingenuous to say that such dislike is nailed to Lisp. Mixing data and code in the memory of a running program is what has lead us to every exploit involving a buffer overflow or a stack smash.

I expoect a different class of problems in their place but self modifying code is rightfully highlighted as unprovably correct.

Lisp is not the only language that can build a string and throw it at an eval function.
