Raspberry Pi to serve up bite-sized modules for bulk-buying biz bods

chris 143

didn't you already post this?

How Microsoft can keep Win XP alive – and WHY: A real-world example

chris 143

I suspect VMs are your friend here

EIther win7 with the xp vm

or

my preferred option of linux + kvm and a windows vm that you clone, use for that day and junk, means any compromise is limited, also dual NICs should allow you to keep windows and the rest of the network as seperate as possible

Re: That's Amazing

Given the pressures it's likely to be some superheated liquid

The answer to the in/out question is probably both. Some water gets carried down by sinking tectonic plates and some rises up again via volcanoes

Intel's new Xeon: Easy to switch between dual memory modes? Uh, no

chris 143

The 5500 series Xeons had mirroring

The 5500 series Xeons could do memory mirroring, (think memory raid1) if a DIMM failed you could schedule downtime to swap rather than the server crashed.

I doubt that the performance mode is unsecure, more that mirrored mode is more secure. If you've got 96DIMMs in a server the chances of one failing is far higher than a 4 DIMM server??

As for the switching modes, boot into the bios change setting reboot. Even on the very slowly booting HP DL360 G6s you should only be 5-10 minutes

Think Amazon is CHEAP? Just take a look at these cloudy graphs...

chris 143

those graphs are pointless if you don't label your axes properly!

price ($) - is that per second/minute/hour/day/month? a one off cost?

Flash stash on toppa platta: WD's tasty Black² 1TB combo for LAPTOPS

chris 143

at £250 you could very nearly get a 500GB SSD

price seems a bit high, for now much more you could get a 500GB SSD and if I had to choose I'd rather have the SSD

Re: Couldn't all this waste heat

Even if you run your servers quite hot the hot air is unlikely to be above 40C. That's simply not hot enough to be particularly helpful for a steam based power station.

You could start using heat pumps or possibly boiling a different liquid but I doubt it'd be worth the effort.

The easiest way to improve the efficiency is to reduce the amount of energy you spend cooling.

Unmasked: Euro ISPs raided in downloads strangle probe

chris 143
WTF?

If I'm reading this correctly.....

The various ISPs refused to upgrade their cogent links?

Given that cogent would probably have charged them for it isn't that fair enough?

Half of youngsters would swap PRIVACY for... cheaper insurance

chris 143
WTF?

Anyone who still believes that insurance drops at 25 is hopelessly deluded

I'm 26 and my insurance is still best part of a grand (5+ years no claims, never had an accident etc)

I didn't bother with the tracking for a simple reason, most of the driving I do is the stuff they'd describe as being high risk (late night, long distance etc)

Re: Managed PDUs and a serial console

It's there but other than setting an IP or rebooting it, you're limited to the windows command prompt which isn't particularly helpful...

Managed PDUs and a serial console

Managed PDUs and a serial console server, if you're managing more than a couple of servers the actual cost per server isn't too bad. Admittedly not that helpful if you're using windows but if you're using linux it can be a life saver if you break your network connectivity

Also even quite old servers generally support serial bios....

twice as fast as qemu?

twice as fast as qemu shouldn't really be that much of an achievement and for $10,000 I'd rather have some xeons

Post-pub nosh deathmatch: Bauernfrühstück v bacon sarnie

not enough bacon

I'd like to point out that you don't have enough bacon in your sandwich.

There should be approx as much bacon as bread (one pack per two slices of bread usually works well)

Experts stroke beards over LOHAN's vacuity

chris 143

If you're worried about the expensive gauge can you use your old one?

Is your previous gauge cheap enough to risk breaking? could you have both gauges, pump down to required pressure on the expensive gauge, take a reading on the cheaper one. Then isolate the expensive gauge and work entirely from your old gauge?

You should know what it read at 20mbar even if it actually read 30mbar you're only interested to see if it changed.

GPS-equipped sheep prove herd mentality exists

chris 143

Is GPS actually accurate enough for this?

I thought consumer GPS was accurate to 3 metres (ish), is that actually enough for this kind of thing? Or atleast more accurate than you could have achieved with some paint (colour coded sheep) and a decent video camera?

Re: 2 screens

I remember playing a zelda game (4 swords I think) on the gamecube which used a gameboy as the controllers, worked really well actually. You ran around on the map using the TV and ever time you entered a cave it switched to a side view on the gameboy

Samsung's projector phone beamed up to Blighty

Thumb Up

Re: Can't imagine I'd actually use the projector much

Yeah me too

Now if they could leave it the bootloader unlocked and not make the phone too expensive I'm sure I could have fun with one of these

LOHAN seeks failsafe for explosive climax

chris 143

Two thoughts:

1) do you have to use the same parachute to pull the cord (I'm concerned that the cable might be just enough to prevent your parachute opening properly)

2) can you use the tension in the cord rather than something on the balloon itself ( two contacts head apart by the tension of the balloon with a weak spring that will pull them together once there is no tension on the string? )

LOHAN sucks Reg reader's instrument to death

chris 143

How do the batteries look?

I've never tried exposing AA batteries to a decent vacuum but I wouldn't be that surprised if they leaked.

Also this is probably a good test to do to your electronics bundle before launch. If they're going to overheat/leak/explode it'd probably be better to find out before launch

Meh

Re: Performance loss at altitude?

I have to agree with you. It sounds like someone gotten confused by a dial that measure the drop in pressure. If low ambient air pressure was a bad thing then we'd never use vacuum pumps in series

LOHAN starts to feel the barometric pressure

chris 143

now if you were willing to use two balloons

you could launch when the first balloon burst, the second ballon should reduce the rate of fall/keep the assembly pointing up long enough to launch.

Also you could use a similar system as you are using to ignite the rocket motor to burn though the cord holding the remaining balloon

chris 143

balloon or similar?

The simplest and probably most reliable solution is to have a balloon that expands as the pressure drops pressing a switch. I'd probably suggest that you'd want two of these in case one fails (better for it to launch early than not at all). It'd be simple, relatively easy to test and lightweight.

A 'launch when the string breaks' system is probably unnecessarily complex. If the objective was just to get as high as possible, you'd be better to abandon all the rocketry and simply build a system as light as possible and let the balloon do the entire lift.

Wireless charging coming to Latitude?

chris 143

won't wireless charging do something pretty horrible to the hard disk?

I'm no physics student (chemistry actually) but won't the wireless charging (generating a nice big magnetic field) cause quite a lot of damage to any magnetic storage like say a hard disk?
