Hi Amias, haven't seen you round here in yonks. (You ever get that Dell
C600 Latitude doing anything useful? Think I gave it to you?)
> If you have 16GB of ram and suspend
No - 4GB RAM & hibernate. ScientificLinux5 doesn't (in my experience)
suspend well. Correction: it suspends & revives fine, but with no video
on reviving, thus not useful. It hibernates really well though.
But a wonder was, is that "hard" on the disk & innards vs just staying
up/on for months.

Agreed 100%. Got 3 USB backups of everything & a laptop rebuild plan
that's been used about 4-5 times now in rebuilding main laptop &
building others to similar format. Watch for hardware errors daily.

Hello Winnie,
yep its been a while , i've been having a baby , she's now 2 and already
using my linux desktop :)
ISTR that laptop is doing something for an internet radio station now ,
thanks .
I think you should request an SSD for your laptop and conduct some
extensive testing with it over the next 6 months for reliability ;)
Hibernate is likely to be heavier on the disks than suspend because IIRC
its a total memory dump or at least much closer to that but if the period
of inactivity is months then its probably worth it. 4GB of writes is quite
possible for a machine that has been idle for a month.
Pretty sure waking up an HDD and stressing it is not great and you don't
get that with SSD which is just instantly ready.
As an aside - hibernate/suspend is a pain with network connections , as a
tester i find it the biggest source of wierd behaviours because of the time
dilation that i can cause in both the host clock and on the server when
trying to re-establish sessions from the past. Logic and rationality fall
apart if time has bubbles in it. In a scientific environment i'd be a
little nervous of this contaminating experiments so might want to provide
an easy way to ensure no hibernate or suspend for users if they need it.
Cheers
Amias

Hello Dave,
ISTR there was a guide in the previous linux voice [1] that covered how to
take an image of an existing xp setup and run in virtualbox.
Passthrough usb should easily be able to cope with photography interfaces.
maybe Ben E knows about how to get hold of back issues
This way you can try all sorts of things but keeping your XP installation
safe in a VM with snapshots and backups , you can also firewall it safely
via linux or better still don't allow it any net access at all.
Dual boot is a world of pain and something i'm very glad i left behind ,
most of us have done this so bare that in mind when asking for help on dual
boot - its tricky , horrible and unnecessary so you should be very very
very grateful if anyone helps you with it because its the Linux equivalent
of mucking out a horse shed.
Personally i don't think meets should be for fixing stuff , really you
should pay people for that because its how most of us earn our living.
Cheers
Amias
[1] linux voice is an excellent read i would heartily recommend a
subscription , beats linux format by miles :)

Chris! Good news!!!
There just wasn't enough power left to run the disk drive and the pc!
That's why it was beeping and shutting down so fast :)
Luckily too, the disk left inside there, when I fired the pc up, was the
boot recovery one, and Suse got under way. I swapped it for the LXF one, and
it went well until Firefox crashed!
So I'm back on XP for this email, and I'll take a look shortly at the BIOS
via f2 to see if its still expecting your memory stick, and then let it do
all the umpteen updates and downloads that expect are waiting in the
wings....
Keeping my fingers crossed that it will work - but a least Grub fired up OK,
and its 3 choices - Suse, XP and I forget what was the 3rd(!) - certainly
fired up Suse and XP.
Many thanks for you considerable efforts. I had to leave KT as I'd lost all
trace of hearing in the high noise level, and that guy opposite had taken
over Dave, so he wasn't going to be of any help to us there and then.
Best wishes,
Dave.

Hi
I'm Malcolm Lamb, I came to visit your 'Linux Live' event and have been mostly using Mint since.
I am hoping to join you at KT this afternoon, family commitments permitting.

you are right it would be a silly to copy all of it to disk but its quite
common
to have around 8gb active , most machines i used these days tend to be using
at least 2GB if not 4GB of their available memory.
SSD longevity is getting better but i don't see it matching HDD for some
time ,
There isn't any real incentive for manufacturers to increase the
reliability of consumer
SSD's beyond basic levels as they will just loose sales volume when they
are still
paying off the R&D.If consumers don't like it they will just pay more for
enterprise class ones.
The most important things i've learnt about storage is everyone needs
different
things from it and spending time considering how you will use it before you
buy pays dividends.

Especially seeing as most consumers just want MOAR MEGGERBITES! (in the same
way they want MOAR MEGGERPIXELS from their cameras, MOAR HOARSEPOWER from
their cars, MORE WHATTS from their stereos and MOAR SATIETY from their
food)

you are right it would be a silly to copy all of it to disk but its quite
common
to have around 8gb active , most machines i used these days tend to be using
at least 2GB if not 4GB of their available memory.
SSD longevity is getting better but i don't see it matching HDD for some
time ,
There isn't any real incentive for manufacturers to increase the
reliability of consumer
SSD's beyond basic levels as they will just loose sales volume when they
are still
paying off the R&D.If consumers don't like it they will just pay more for
enterprise class ones.
The most important things i've learnt about storage is everyone needs
different
things from it and spending time considering how you will use it before you
buy pays dividends.

Especially seeing as most consumers just want MOAR MEGGERBITES! (in the same
way they want MOAR MEGGERPIXELS from their cameras, MOAR HOARSEPOWER from
their cars, MORE WHATTS from their stereos and MOAR SATIETY from their
food)

Reet luggers,
i have a hunch that suspending and resuming might not be great for SSD's as
they can have quite a limited amount of writes before failing compared to
HDDs . Some basic models are really quite shocking so check for long term
reviews before buying cheap ssd's.
but then i am testing enterprise grade storage systems these days so my
'limited' might not be the same as yours.
If you have 16GB of ram and suspend that is quite a lot of data , i guess
you'd not be helping longevity much if you didn't expect the machine to
write 16gb in the time span it was suspend for if it wasn't suspended ,
which i would imagine is the majority of cases.
That said , SSD's speed makes suspend and resume so smooth it makes me
wonder if its actually done it most of the time.
The other benefit of SSD's (at the moment) is that they are small so they
kind of imply using external storage which will actually increase
reliability by providing some redundancy , something that previous hdd
owners might have passed up on. I think its a good thing to expect your
disk to fail and ensure you are covered rather than hoping it wont and
losing data.

There was a study recently, which tested lots of different SSDs
writing continuously over months, and found most of them, but not all,
tolerated a lot more writes than their specification implies.

If you have that much RAM, and don't churn through that much data
between suspendings, I'd hope the OS was smart enough to not rewrite
what it had already stored a copy of in swap space from the previous
hibernate.

With SSD there's no advantage to restore that part of RAM which is
filesystem cache and mapped files, which for most users with a lot of
RAM is likely to be nearly all of it. The effect is like doing a
filesystem cache flush, but the SSD is so fast subsequently that you
hardly notice. With a HDD, it's more of a compromise, because doing
that after resume results in a lots of slow seeking as soon as you
continue doing things.
The same applies to application memory which is swapped out for
hibernate. There's no advantage to swapping it all back in on resume
with SSD; pages might as well be fetched on demand, about as quickly.
That's all theory; I don't know what the various OSes actually do.
On a Macbook, it doesn't even write to storage straight away on
suspend. First it suspends to RAM, then silently commits to storage
after a little while, so you don't see the process taking time. That
gives you a combintion of benefits, and is very sensible, but I don't
know if the other OSes have adopted it. I always worried it might be
not very safe waking the HDD while it's jiggling about in a backpack;
but with SSD that's not a worry.

SSDs aren't all small :)

I was just looking through some pi solutions on remote control of power
sockets (other thread) and found "Energenie Pi-mote". After realizing I
need (even at my age) some basic python experience, I found this book
recommended:
"Learning Python with Raspberry Pi" by Alex Bradbury and Ben Everard.
I now know who to ask if I get stuck!

Hi,
The manufacturer's have just agreed to send me a pi-mote and some sockets to review for Linux Voice. I can let you know what they're like.

Hello Peter,
I would just use a wired machine to login to the web interface of the
router and enable and disable the radio as thats where the power draw is.
quite a few have cli's that you can automate to do this via ssh . if you
are still using the netgear dg834g then it definitely can.
I suspect this endeavour might save you around 10 to 20 pounds a year , so
be aware of spending anything to solve it .
if you really want to reduce your environmental impact switch to a fully
renewable energy supplier , there is very little difference in price but a
massive difference ethically , politically and ecologicially.
You could also run it from a solar panel with a battery backup as most of
them run on 12v and don't pull more than 1 or 2 watts.
Cheers
Amias

If you're still using a DG834G connected to the InterEvil then I hope
you've checked it for security bugs like TCP-32764, plus maybe WPS
bruteforce unless your neighbours are saints.

Thanks for this; I've looked at home automation technology before but I
think this is the first one that meets the criteria of 1. only software
hacking needed, 2. has reasonably low level and versatile access to the
actual network and 3. this can be done from a standard Linux box with
open source software. Very interesting...

A couple of links for those interested:
http://www.raspberrypi.org/forums/viewtopic.php?t=34091
http://www.uk-automation.co.uk/categories/Z%252dWave-Automation/
The only problem I read was that someone with python experience (not me)
had to alter a script to make it "pole" devices more often (excuse
terminology), but I am sure that's not a problem for most on here!
It is interesting though.

A couple of links for those interested:
http://www.raspberrypi.org/forums/viewtopic.php?t=34091
http://www.uk-automation.co.uk/categories/Z%252dWave-Automation/
The only problem I read was that someone with python experience (not me)
had to alter a script to make it "pole" devices more often (excuse
terminology), but I am sure that's not a problem for most on here!
It is interesting though.

Hello,
I'm Ben (one of the team from Linux Voice magazine- www.linuxvoice.com). I'm in the process of moving to Bristol at the moment, and should be in town on 28th, so I'll try and make it.
See you there,

This needs to be physically connected to the raspberry pi so that?s possibly not a practical solution. The core of that system will be one of these, a 5v relay that you can easily power/control from the raspberry pi GPIO pins. I?ve got one sitting in my drawer, I?ve had it working but it?s not a functional part of the system yet.

Thanks for all the replies and references.
The Swedish dongle for the pi looks interesting and I will keep and eye
on lidls/wilko/aldi for offers, the problem seems to be like the old
WiFi cards, they may not have compatible protocols.
Maybe I should check to see if my Harmony 600 R/C can do something, it
can connect to most things!!
On the general points mentioned, I realize using a pi to switch the
router might not be much (if any) of a saving but it seems an
interesting project that can be used for other things about the house
like others have stated.
Yes, I am a bit tempted by new gadgets, but I don't was to get too
involved in programming or making 8 way network switched power blocks
from parts.
I assume John H is away as this was "right up his street"!

I'm here, but TBH I haven't done anything with the Raspberry Pi! I'd
agree with the advice to try out a cheap radio-switched socket from
Aldi, Lidl, Wilkinson's or wherever, though. Just be sure, as somebody
mentioned, that it doesn't consume more power than the thing it
switches.
You could try asking on the Bristol Hackspace mailing list:
http://bristol.hackspace.org.uk
PS. Will probably be at the LUG on Saturday.

I'm kind of hoping to find some really cheap data-over-powerline
driver chips (serial speeds will do fine 9k6 is plenty) to combine
with a home-brew arduino and do all of the electronics myself, but the
data-over-power drivers have always been the limiting factor. My
experiences with whole-home RF have been less than stella.

Hi,
Have you not looked at Z-Wave devices?, using a mesh approach. Friend of
mine in Norway is playing with this from a Pi.

Yes it's looking like it's going to be a good turn out :), the more the

Thanks for all the replies and references.
The Swedish dongle for the pi looks interesting and I will keep and eye
on lidls/wilko/aldi for offers, the problem seems to be like the old
WiFi cards, they may not have compatible protocols.
Maybe I should check to see if my Harmony 600 R/C can do something, it
can connect to most things!!
On the general points mentioned, I realize using a pi to switch the
router might not be much (if any) of a saving but it seems an
interesting project that can be used for other things about the house
like others have stated.
Yes, I am a bit tempted by new gadgets, but I don't was to get too
involved in programming or making 8 way network switched power blocks
from parts.
I assume John H is away as this was "right up his street"!

I'm here, but TBH I haven't done anything with the Raspberry Pi! I'd
agree with the advice to try out a cheap radio-switched socket from
Aldi, Lidl, Wilkinson's or wherever, though. Just be sure, as somebody
mentioned, that it doesn't consume more power than the thing it
switches.
You could try asking on the Bristol Hackspace mailing list:

I'm kind of hoping to find some really cheap data-over-powerline
driver chips (serial speeds will do fine 9k6 is plenty) to combine
with a home-brew arduino and do all of the electronics myself, but the
data-over-power drivers have always been the limiting factor. My
experiences with whole-home RF have been less than stella.

Hi,
Have you not looked at Z-Wave devices?, using a mesh approach. Friend of
mine in Norway is playing with this from a Pi.

I do this a reasonable amount, I have my central heating controlled by raspberry pi amongst other things.
Right now I?m using a network PDU for the heating and other critical controls, this is working fine but takes up a lot of space, where I use wireless power sockets are for the fish tank lights and a ?daylight alarm clock? which is where the lights come on slowly over a ten minute window to wake you up in the morning. The downside of using remote power sockets is it?s simplex - there is no feedback to confirm the state change and as with all communications channels there are losses.
For this I?m using a ?tellstick duo? which comes from a swedish company, this is a little USB module that plugs into the Pi and can transmit to most of the cheap receivers you can get, for simple on/off it seems to work with 90% of brands, for dimming it?s a lot more fussy and additionally some of the receivers themselves do a good job, for example the protocol specifies 256 levels of brightness however with one of the receivers that I have this maps onto about 10 discrete levels, the lowest of which I estimate to be around the 70% level. The other dimmer receiver is almost imperceptible when on at it?s dimmest which is ideal for the alarm clock.
There are cheaper approaches, for example you can use a arduino with a 433.92 MHz transmitter to talk to the same protocol but it?s a lot of work getting this working and I?ve found it's very much a case trial-and-error so unless you?re interested in the process or have future plans I?d recommend sticking with the tellstick.
What I?m looking at currently is wireless temperature sensing with a arduino, a temperature probe and some nRF24L01 wireless modules that work with both arduino and raspberry pi, this again is partly for fun but also because the Arexx bs-1000 that I?m currently using is just not very good.

What's the motivation for keeping it off when unused? Power savings?
The educational fun of building a remote switch? Because it's the
future and you want your jetpack? Many moons back I bought an X10
wirelessly switched plugthrough socket with the goal of saving power
when stuff didn't need to be on. I got warm fuzzies from using it, but
later I borrowed one of those plug-through watt-meter thingys and
measured everything, and found it was quite thirsty itself with or
without the load plugged in --- more thirsty even than the thing I'd
controlled with it, which was a disappointing own-goal.
So if efficiency is the aim and you're buying a widget, see if you can
find the widget's own power draw in its specs.
I've never tried it and my hardware-fu is non-existent, but I've a hunch
that if your Pi is always on anyway, a homebrew setup with a relay would
consume the least.

^ This.
If you're determined to do something like this, Lidl have the plugs and
controller on offer periodicaly for about ?13-15.
Even Wilkinson have them (exactly, by appearances, though possibly with
fewer plugs) for ?20:
<http://www.wilko.com/switches+sockets/wilko-remote-control-wall-plugs/invt/0343066?VBMST=remote%20mains>
I use my Lidl ones for a bunch of uplighters, a table lamp, and to power off
an active subwoofer that would probably annoy my neighbours late at night if
watching a movie.

Hi
Wouldn't leaving the router on be a much easier solution. Most routers
and wireless routers only use (at max) 3w. Have a separate extension
lead for the stuff that is to be kept on.
Found some cheaper ones:
REMOTE CONTROL MAINS SOCKET ADAPTOR SET - 5 PLUG IN SOCKETS & REMOTE
INCLUDED
http://www.ebay.co.uk/itm/REMOTE-CONTROL-MAINS-SOCKET-ADAPTOR-SET-5-PLUG-IN-SOCKETS-amp-REMOTE-INCLUDED-/161336288206
?24.49
specs for above:
Voltage 240Vac, 50Hz
Max. load 2400W
Max. current 10A
Transmission frequency 433.92MHz
Remote battery 12V, A23
Socket dimensions 112 x 58 x 65mm
Remote dimensions 81 x 35 x 15mm
Standby Power 1.0W
Interesting project.
This maybe a better option for your needs:

I usually just lurk, but I'll be there Saturday, for the duration.

I do this a reasonable amount, I have my central heating controlled by raspberry pi amongst other things.
Right now I?m using a network PDU for the heating and other critical controls, this is working fine but takes up a lot of space, where I use wireless power sockets are for the fish tank lights and a ?daylight alarm clock? which is where the lights come on slowly over a ten minute window to wake you up in the morning. The downside of using remote power sockets is it?s simplex - there is no feedback to confirm the state change and as with all communications channels there are losses.
For this I?m using a ?tellstick duo? which comes from a swedish company, this is a little USB module that plugs into the Pi and can transmit to most of the cheap receivers you can get, for simple on/off it seems to work with 90% of brands, for dimming it?s a lot more fussy and additionally some of the receivers themselves do a good job, for example the protocol specifies 256 levels of brightness however with one of the receivers that I have this maps onto about 10 discrete levels, the lowest of which I estimate to be around the 70% level. The other dimmer receiver is almost imperceptible when on at it?s dimmest which is ideal for the alarm clock.
There are cheaper approaches, for example you can use a arduino with a 433.92 MHz transmitter to talk to the same protocol but it?s a lot of work getting this working and I?ve found it's very much a case trial-and-error so unless you?re interested in the process or have future plans I?d recommend sticking with the tellstick.
What I?m looking at currently is wireless temperature sensing with a arduino, a temperature probe and some nRF24L01 wireless modules that work with both arduino and raspberry pi, this again is partly for fun but also because the Arexx bs-1000 that I?m currently using is just not very good.

What's the motivation for keeping it off when unused? Power savings?
The educational fun of building a remote switch? Because it's the
future and you want your jetpack? Many moons back I bought an X10
wirelessly switched plugthrough socket with the goal of saving power
when stuff didn't need to be on. I got warm fuzzies from using it, but
later I borrowed one of those plug-through watt-meter thingys and
measured everything, and found it was quite thirsty itself with or
without the load plugged in --- more thirsty even than the thing I'd
controlled with it, which was a disappointing own-goal.
So if efficiency is the aim and you're buying a widget, see if you can
find the widget's own power draw in its specs.
I've never tried it and my hardware-fu is non-existent, but I've a hunch
that if your Pi is always on anyway, a homebrew setup with a relay would
consume the least.

^ This.
If you're determined to do something like this, Lidl have the plugs and
controller on offer periodicaly for about ?13-15.
Even Wilkinson have them (exactly, by appearances, though possibly with
fewer plugs) for ?20:
<http://www.wilko.com/switches+sockets/wilko-remote-control-wall-plugs/invt/0343066?VBMST=remote%20mains>
I use my Lidl ones for a bunch of uplighters, a table lamp, and to power off
an active subwoofer that would probably annoy my neighbours late at night if
watching a movie.
Best Regards,
Alex

Hi
Wouldn't leaving the router on be a much easier solution. Most routers
and wireless routers only use (at max) 3w. Have a separate extension
lead for the stuff that is to be kept on.
Found some cheaper ones:
REMOTE CONTROL MAINS SOCKET ADAPTOR SET - 5 PLUG IN SOCKETS & REMOTE
INCLUDED
http://www.ebay.co.uk/itm/REMOTE-CONTROL-MAINS-SOCKET-ADAPTOR-SET-5-PLUG-IN-SOCKETS-amp-REMOTE-INCLUDED-/161336288206
?24.49
specs for above:
Voltage 240Vac, 50Hz
Max. load 2400W
Max. current 10A
Transmission frequency 433.92MHz
Remote battery 12V, A23
Socket dimensions 112 x 58 x 65mm
Remote dimensions 81 x 35 x 15mm
Standby Power 1.0W
Interesting project.
This maybe a better option for your needs:
