I completely agree with that... as you say, the customer is likely to
upgrade anyway and that has the potential to break the thing... better
to install the latest release, fully test it to ensure it works and
then you know that they have 6 months of relatively plain sailing at
least... we had that thread a week or two ago with Rowan and his
networking which was caused by a supplier having to install
non-standard drivers due to something (the kernel version?) in 8.04...
that's after less than 12 months...

8.04 will cease to be supported (desktop) in April 2011, 9.04 will
cease to be supported in October 2010... we're getting to the point
here where there isn't actually a great deal of difference.

Looking at the hardware, you're looking at about 110-130 plus 20 for
national delivery plus a bit for you so lets say 180 a unit-ish.

As for everything else Mr Pope is correct get onto Canonical for
permission to use the ubuntu branding if nothing else.  If I recall you
have to send a sample machine in to canonical but again chase that up
with them after all they know.

 I'm looking to offer a base unit, 2GHz dual core Celeron (E1400) with
 2GB DDR2 PC2-6400 RAM, and a 150GB SATA hdd. Graphics, sound and
 ethernet are onboard.
 

 My only comment - apart from to agree with those who commend that you
 use the LTS version - would be this: I would never buy a Celeron and I
 tell everyone, friends and clients, to avoid them. They are nasty,
 crippled devices and anything with a Celery in it is probably
 rubbish, in my not-at-all-humble opinion.

 I'd rather have a cheap low-end but full-spec AMD or Via chip than a
 Celeron. Yes, I know it's possible to replace a Celeron with a
 full-spec chip, but almost nobody ever does  it's almost never an
 economical upgrade.

   

Actually the dual core Celerons are pretty quick.  They are based on the 
Core 2 Duo core with just a smaller cache.  To be honest I would presume 
that a system for about £200 would not be aimed at a power user and with 
some people finding that a single core Atom at 1.6GHz does the job 
(heck, a Duron 1400 with 512MB Ram I built the other day is fine for web 
browsing) then a Celeron Dual Core would probably be fine.

Saying that though, I'd rather have a Core 2 based Celeron Dual Core or 
Pentium Dual Core rather than the older Pentium 4 Prescott based Celeron 
D (my kids PC has one in and while it's fine for what they want and 
pretty quick at 3.33GHz it's really power hungry and runs hot).

I do agree about the AMD chips though, if you can get one cheap enough 
and a decent AM2+ board then you could at a later date drop in an AM2 
(and I believe AM3) Phenom II onto the board (although for best 
performance you really need a board which can support the faster HT 
speeds of the Phenom which some of the cheaper AM2+ boards don't support).

PCM is Pulse Code Modulation, the main method for describing sound

microseconds you take a measurement of how high or low the wave is at
that point. The points are called pulses and the measurements are
called codes.

PCM is used for all sampled sound, which these days is almost all played
back sound from a PC. Depending on the implementation, MIDI GM sounds
may or may not be controlled via PCM. For example, a card which
implements MIDI GM sounds in software will almost certainly use PCM,
whereas a card which implements MIDI GM sounds in hardware might not.

 2009/3/25 Matt Jones m...@mattjones.me.uk:
   
 In the past, that opinion was fairly valid. Now, the celerons are
 actually quite speedy little chips, espescially for an Ubuntu box that
 is going to run web/openoffice/music all day. As for recommending a
 Via over the current (Dual core) celerons, they are quite a long way
 behind in performance terms, and not really any cheaper.
 

 I am aware that the Via Nano is not as powerful, although it compares
 very well to the Intel Atom, but then, the Nano uses a *lot* less
 power than a Celeron so the overall running cost would be somewhat
 lower.

   
Actually, tests done by Tom's Hardware Guide suggest that overall the 
Core 2 is a more efficient chip than the Atom.  It's just a case of 
paring it with the right hardware.

http://www.tomshardware.com/reviews/intel-atom-efficiency,2069.html
 But still, seriously object to the pricing model of producing crippled
 chips with tiny L2 caches and selling them cheap. If they can make a
 profit on the crippled model, they could make one on selling the
 premium product with the full-sized cache for a lot less. There is a
 balance to be had, and that balancing point is called a fair price.
 Instead, we get cheap crippled chips - the Celerons, Pentium chips,
 AMD's old Durons and so on - and price-inflated professional or
 performance chips for power users.

   
 From what I understand these 'crippled' chips are basically the higher 
end chips which don't at full spec, for instance a Celeron Dual Core 
could well be a Core 2 Duo which a section of cache on doesn't work.  
Rather than just chuck the chip away they disable some of the cache and 
sell it on as a cheaper part.  AMD do the same with the Phenom X3 (and 
newer Phenom core based Athlon X2's) where they disable a faulty core 
and sell them as a slightly cheaper chip.  To be honest considering what 
sort of financial state AMD are in at the moment they need to do this to 
recoup some of the costs and pay off some of the debts.

There is also the fact that if you're so inclined it is possible to 
overclock some of these chips (especially the Celeron Dual Core and 
Pentium Dual Core) to much faster speeds.  I managed to get about 3GHz 
from my 1.8GHz Pentium Dual Core, sods law though the power saving 
driver in Linux clocked it back to it's original speed.
 This is a deliberate pricing model; in the industry, it's called
 something like segmented marketing and catching the low end. I call it
 screwing your customers. Which is one reason I prefer to deal with
 companies who don't play those games. The AMD tactic of selling last
 year's model cheap and calling it a Sempron or something was much
 more honest and fair, and indeed I am typing on an AMD Athlon box now.

   
Technically last year's model would be the Athlon X2 which they are 
still selling as an Athlon X2, albeit fairly cheap although I'm yet to 
see any Sempron X2's in the shops (IIRC they do sell them in very small 
quantities overseas).
 Alas, since their 64-bit leap, AMD have no new tricks to pull and the
 CPU high end now belongs completely to Intel. It's a damned shame.
   
Actually the Phenom II is starting to claw back some of the 
performance.  Considering if you have an AM2+ board you can drop in a 
Phenom II X4 straight onto the board that is a pretty good performance 
upgrade especially compared to the new Core i7 which needs a new board 
and DDR3 memory (and if I'm correct they are replacing the socket on the 
Core i7 again later on this year).  If you were to stick an AM3 CPU on 
an AM2+ board then you have extra future proofing as you can upgrade to 
an AM3 board and DDR3 memory when the prices come down.

I regularly display (infopoint  -information re foss and ubuntu) at a

However they still struggle with many basic questions. But they are 
installing it themselves into unknown machines. Unfortunately they are 
not very likely to yet be users of discussion forums such as this one.
Some are very keen to escape from windows.

What comes to my mind is that on occasions when I have provided a pre

occasional detailed support from me which is of great value, more than 
the machine itself. These friends are not people who would be 
comfortable with, say, this list. But they would probably pay for 
suitable personal support over time.

If you are selling hardware with known linux suitability then well 
seasoned users like myself might be certainly interested, just to know 
that certain hardware is ubuntu suitable and get some information and 
subsequent (list based?) support hopefully.

However, I would be a very different type of customer to the elderly 
lady I met on a cruise up the norwegian coast who was set on buying an 
Asus eee (901 I think) after seeing them in a newspaper report, and 
she would probably never want to install anything herself.

As you say, if you intend to compete on hardware costs alone there is 
a lot of competition. Less competition and more welcomed market 
possibly if you consider certain levels of information/support.

[ubuntu-uk] Squid proxy box with serious IPv6 DNS problem...

2009-03-26 Thread LeeGroups
Chaps...

Over the last couple of days I've been trying to build a proxy box for a 
load of Windows PCs, using Squid on Ubuntu server 8.04.
I've had a few problems with it due to the wild/wacky filtered internet 
connection we have there, but now I've hit a massive brick wall...

Using an upstream proxy config Apt can get out to the internet fine, 
download and update the OS.

However, Squid can't resolve any DNS loopups... it just fails a few 
minutes after loading.

Doing a wget of a known file like the Google index page also fails with 
a unresolved DNS error.

However, (after much much much reading) using the -4 option of wget, to 
force it to use IPv4, it works fine, resolves the Google address and 
downloads the index page and saves it.

I've blacklisted the IPv6 service, but wget (and Squid) still doesn't 
work without the -4 option, so I guess bits of IPv6 are still hiding 
there somewhere

My question is - How do I fix this bloomin' thing?  I've been googling 
for hours with only the -4 option to show for it... and I really need to 
get this this working for Friday afternoon...  Otherwise bad Windows 
things may happen...

Re: [ubuntu-uk] Squid proxy box with serious IPv6 DNS problem...

2009-03-26 Thread Alan Bell
I think from the description the squid thing is actually a red herring. 
(to mix a fishy metaphore). It sounds like your proxy server is not 
reliably resolving DNS when using IPV6. You will probably see this 
problem if you run firefox on the server.
https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/24828

not sure how you turned off IPV6, one way is to edit
/ /etc/modprobe.d/aliases
and edit it to have this line:
/alias net-pf-10 off ipv6

a better solution would be to fix the actual problem, one way might be 
to point your proxy at openDNS which works fine with v6. I suspect the 
DHCP server is pointing your box at a bad router for DNS queries.

 work without the -4 option, so I guess bits of IPv6 are still hiding 
 there somewhere

 My question is - How do I fix this bloomin' thing?  I've been googling 
 for hours with only the -4 option to show for it... and I really need to 
 get this this working for Friday afternoon...  Otherwise bad Windows 
 things may happen...

Re: [ubuntu-uk] Squid proxy box with serious IPv6 DNS problem...

2009-03-26 Thread LeeGroups

Alan,

I'm actually using OpenDNS's servers (after using the ISP's), what I 
really don't understand is how Apt is working perfectly, but Squid and 
Wget don't...

I saw that post before, it's what I used to supposedly turn off IPv6.

I can't run FF on the server, no gui installed...

 I think from the description the squid thing is actually a red herring. 
 (to mix a fishy metaphore). It sounds like your proxy server is not 
 reliably resolving DNS when using IPV6. You will probably see this 
 problem if you run firefox on the server.
 https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/24828

 not sure how you turned off IPV6, one way is to edit
 / /etc/modprobe.d/aliases
 and edit it to have this line:
 /alias net-pf-10 off ipv6

 a better solution would be to fix the actual problem, one way might be 
 to point your proxy at openDNS which works fine with v6. I suspect the 
 DHCP server is pointing your box at a bad router for DNS queries.

 Chaps...

 Over the last couple of days I've been trying to build a proxy box for a 
 load of Windows PCs, using Squid on Ubuntu server 8.04.
 I've had a few problems with it due to the wild/wacky filtered internet 
 connection we have there, but now I've hit a massive brick wall...

 Using an upstream proxy config Apt can get out to the internet fine, 
 download and update the OS.

 However, Squid can't resolve any DNS loopups... it just fails a few 
 minutes after loading.

 Doing a wget of a known file like the Google index page also fails with 
 a unresolved DNS error.

 However, (after much much much reading) using the -4 option of wget, to 
 force it to use IPv4, it works fine, resolves the Google address and 
 downloads the index page and saves it.

 I've blacklisted the IPv6 service, but wget (and Squid) still doesn't 
 work without the -4 option, so I guess bits of IPv6 are still hiding 
 there somewhere
