This was done in the '80s by ITV as well. I recorded the game 'Pud Pud' which was broadcast over the TV. Primitive, but it actually worked. Anyone remember the 'flexi discs' on the front of magazines? They were very thin floppy records which you played using your record player into your computer. I predicted at the time that this would NOT take off, and my sage visions proved accurate.

Spot on - we've got several thousand users going through the boxes (thousands of machines in lots of schools), so we need some kind of balancing. I need a deterministic algorithm to make best use of each of the server's caching. It's working OK at the moment (even with my embarrassingly poor algorithm), but I want to make it as good as possible.

Tune in at 11:59 to see some serious action.

Good stuff. I've posted it elsewhere, but this (link) was the first program I typed in from a magazine (waaaaaay back to Christmas '82). I still maintain that Sinclair Basic has the best string slicing (TO) of any language I've seen since.

Does anyone have a working squid.conf file they can post which uses CARP with parent peers? TIA.

That's the best thing I've ever seen in my life. And I've seen a LOT of things.

Another Unity fan? I'll be on the third bench along reading a copy of the Times. 7pm. Make sure you're not followed.

Successfully upgraded. Upgrade 'net speeds were horrendous, between 20kps and 60kps, but I ran it in the background and it was able to resume the upgrade in several sessions over the course of a couple of days. No problems, and it's great (so far!).

Indeed. We've been 'sweating these assets' for too many centuries. Time for some maintenance.

Thanks guys. My home-brew solution is not looking too promising. I'm running filtering, proxying (of course) and caching on all my Squid servers. It's more complex still as I have NTLM and basic as failover. So is the consensus that if I'm using Kerberos then CARP won't work in Squid, even as parent?

Hold on - are you talking about the Squid CARP? The Cache Array Routing Protocol (CARP) This is the one I meant. I know there is a different CARP, but this CARP is definitely for load balancing against a hash of the URL. Every time I restart my front-facing Squid server with the "cache_peer carp" directive my Kerberos authentication goes west. It's as if the ticket has expired. The other peer servers work correctly on their own, and as part of an array from a pac file. I could just write something in Java to achieve the same thing from the PAC file, as I can just copy a hashing algorithm off the net.

Thanks, Tom. Everything I read about Carp says it's the best thing in the world for load balancing. Well, perhaps not quite that, but they do drift towards that impression. I will check out you link for load balancing - thanks.

Not much more to add, really..... http://youtu.be/SKRgktzRvZ0

Thanks. I don't really want round robin though. I read the draft RFC for CARP and it mentioned a fairly sophisticated load-balancing which is what I want. Apart from filtering, the servers must cache and it would be best if the URLs were directed to the 'correct' server to make the most of the caching. The documentation is frustrating. What I'd like: Front end Squid (with fail-back caching in case a peer went south) > Carp hashes the URL > Passes to the appropriate peer server based on the URL > Server returns cache hit or fetches from the internet > happy bunny. I've got a cluster of Squid servers, but the distribution is based on a crummy algorithm in the pac file.

Is anyone using Squid with CARP peers? In a nutshell, I have a group of Squid proxy/cache servers working fine (on Centos 5), but I want to move away from my primitive (awful) hashing algorithm in my PAC/WPAD files to a proper load balanced system. I've read that CARP can provide a solution, but can't get it to work. I've gone through the obvious documentation I could find, but I'm frustrated at the lack of explanation of key points (why would you use sibling instead of parents in your CARP array, for instance). I'm adding cache_peer lines to my squid.conf, but my peer servers aren't receiving any directed traffic. i.e. I've done something wrong. Any pointers?

This is good news about the upgrade. I'm going to wait a day or so to give the servers breathing space, I have a feeling they're hammered right now.

I could live within those constraints.

I suppose it has be packed securely, what with $10.7 billion loaded on it. Mind you, it strikes me as an odd way of transferring money half way across the world. I hope they remembered to note down the PIN.

Ah, good. I upgraded from 11.10 to 12.04 and it's been OK. I'll probably give it a few days (just in case of any show-stoppers) then upgrade. I have quite a few things coming in through ppa, so I'll wait for these to catch up. Does anyone know if there's ANY point in a fresh install? I have a separate /home partition so there's no problem there.

Damn - I didn't spot that. Is it too late to cancel?

One pass should be enough. Disk Wiping - One Pass is Enough | Anti-Forensics "The Great Zero Challenge" was never accepted by any data recovery company. A disk was single-pass wiped with zeros and a prize was offered to anyone who could recover anything from the disk. Although it was a bit of a gimmick, nobody tried to do it.

Good fun. He has an amusing writing style.

Router/switch OK? Try connecting a latop to it using a portable hub/swicth to eliminate anything silly.

I've never liked destroying disks, it seems very wasteful. A software wipe will do the trick - make sure it's a proper tool like the above-mentioned DBAN. A single pass will be sufficient. Keep them as spares; you never know when they'll be handy. I had a panic with a failing disk on a latop and was able to copy most of it to a spare disk set up in a USB recovery rig. Very handy.

set rs = conn.execute("SELECT * from PS_AD_UPDATES WHERE FIRST_NAME LIKE '& FirstName' and LAST_NAME LIKE '& LastName' ORDER BY DATETIME_STAMP;") should be set rs = conn.execute("SELECT * from PS_AD_UPDATES WHERE FIRST_NAME LIKE '& FirstName &' and LAST_NAME LIKE '& LastName & ' ORDER BY DATETIME_STAMP;") You forgot the additional '&' when building your string.
