CAPTCHA for CASH - The end is nigh for the CAPTCHA
I thought you may like to know (unless I'm the last one to cotton on!) that a scenario we've theorised about on the ASRG mailing list for years is finally here, there's now at least one commercial service that will translate CAPTCHA's for cash.
I found the link (shown below) to a service that will decode captcha's for you for $2 per 1000 successes. (Ironically it was in an ad served to me by gmail.)
So to anyone who ever proposed a spam "solution" that relied on differentiating between people and machines, and doubted us when we told them that the commercial imperative would be its downfall, read this:
We told you so, and it only costs two bucks for a thousand!I predict much more of this in time, with costs falling as more competition enters the market, and I honestly think it presages the end of the useful life of the captcha.
That isn't $2 per success - it's $2 per 1000 successes. Minimum purchase is $10 = 5,000 spam, er, advertising opportunitiesThanks Kevin, I've updated the post to reflect this.

Incidentally, some of the spam filter companies, as part of their technology for trying to figure out whether the jpeg is naughty or not, _claim_ they can solve >90% of all captchas on the fly.
note to self, how to change the definer of a mysql stored procedure
This is a useful one if, like us, you find that the account used to create the procedure doesn't have the privileges required to execute it, or perhaps you've revoked the original definers grant. (DoH!)
Facebook, you make me want to cry!
It seems that the way in which facebook chooses an image to show alongside a posted link differs for links posted in different ways.
Oh how fucking hilarious. Not.
On our product page if you "attach" the link, or share it using facebook sharer (http://www.facebook.com/sharer.php) it picks the big product image as the first image in the list for you to choose from. This is a Good Thing, and exactly what we want to achieve.
However if you click the like button, its picking up a random image from sets of smaller images elsewhere on the page.
e.g. Share this dress' page through the sharer, or by "attaching" and you see this image:
but if you use the like button it shows us this image,
which is for this dress.
Arrgghh that's annoying. Get a damn grip facebook, at the very least you could try to be consistent. Read about the principle of least surprise.
Oh Dear poor facebook!Facebook appears to be unavailable for many users, our office included.

note to self, how to use your favourite editor for the crontab without changing it permanently
I like to use nano to edit the crontab, but I don't want to change the default editor.
(Some people are very un-funny about that kind of thing!)
This is the one-liner to use nano, and I seldom remember it.
env EDITOR=nano crontab -e

Another piece of DBA hoodoo that I seldom need!

Another one that I have to google every time.
Not being a DBA I don't do this very often, but now and again I find myself in the Hot Seat.

I've been Scammed! (not really... but he tried his best)
Be safe.. the following describes an attempt to scam me into giving someone remote access to my PC, I was in a playful mood so I strung him along, don't you do that same thing unless you *know* what you're doing. And above all never let anyone remotely access your pc unless you're 100% sure that you ant them to.
I just got a call from a company calling themselves "virtual pc doctor".
He said that I was being called because I was a microsoft registered user.
The guy got me to log into my pc.
Then we clicked the start button and he got me to tell him if it said "computer" or "my computer".
Then we looked at the event viewer, he told me that the errors and warnings were some kind of dire "online infections" that can't be detected by anti-virus.
Woo, scary techno-shit, I thought (not!)
Then he asked me to open www.logmein123.com.
I didn't. I googled it instead.
He told me that a technician would log in, and cure these infections and install a "gateway" which would prevent further infections.
At this point I challenged him about the "online infections" and told him that I didn't think "dhcp client cannot obtain address" was very serious at all.
He said that if I thought that then that was my choice, but my computer could be irreperable damaged.
"oh!" I said, "how?"
"by corrupting the harddrive and the operating system" said he,
"OH!" I said, "Thats, bad. But what kind of software is capable of damanging the hardware? I can just re-install windows can't I?"
"No, because this is new, in the past few weeks, thats why we are giving you the call"
So I asked him where his company was located, and when he said the UK I asked him for registration details.
He Rang Off.
I reported the scam to trading standards.
If he calls you, hang up and report it yourself. Be safe!
