Re: Electric planes?

I think the idea is that if they could run it on electricity then they'd have the option of alternative fuel options.

Also not being left behind if someone does develop a good fuel cell/battery/nuclear fusion/fusion energy source, maybe there's some efficiency to an internal generator, but I doubt it was ever the objective, just good enough for powering the test engine

How'd your servers get that baby-smooth look? Dutch and Brit cool kids dunk Supermicro systems in synthetic oil

chris 143

Re: Practical question

I don't think it's significantly more magical than lift it out and try not to drip oil all over the floor.

I've seen demos where they'd more or less taken the top off a 1U/2U server and removed the fans then dunked it in a vat of oil.

Apparently ssds/helium hdds are happy enough being submerged too. Although I imagine it'd invalidate any warranty

Who crashes a self driving car?

I buy a self driving car, I'm driven around by it.

Sure I might want theft insurance, but assuming I maintain it to the agreed standard any crash it's involved in isn't my fault - I was a passenger - it's $manufacturers.

I don't see them wanting to take on that liability.

Re: Poor build quality to blame ?

Gluing hard plastic and flexible straps together can't be easy, but they've not managed to solve the problem either.

But my other half has the ALTA and metal strap. Which managed about 9 months before it also broke. So it's more than just issues with glue. Feels like there could be something lacking in the basic design quality too

I don't think quite true but being acquired was probably the only way various investors would be seeing their profit.

Re: What about the NICs?

I don't think you'll be putting a 400GB nic in the back of a sever any time soon, largely due to the speed of the pci-e 3 bus.

HPE's cloud server wasting away on low calorie Microsoft sales

chris 143

Re: "Low Cost" and "Data Center"

That doesn't apply to the same extent if you're running azure sized quantities of servers.

Any licensing costs are an accounting trick (microsoft selling to microsoft). Once you're up to the big cloud providers scale worrying about individual server reboots just doesn't make sense.

The ideal cloud native app just spins up a new node if one goes away for some reason.

Seems to be better than it was. Having been quoted lead times in months before mostly things seem to be arriving within a couple of weeks (about what were were seeing a year ago)

Also the 25G costs are pretty similar to 10G..

Windows 10 pain: Reg man has 75 per cent upgrade failure rate

Linux system upgrade may not be much better

As someone who's been happily running Linux on the laptops and desktops in my life for years.

The actual ability to run a dist-upgrade successful may not be a lot better. Put cd in, install it'll almost certainly just work. Several years later when you want to update to the new current version? Consider starting from scratch with the new install cd

I'd be surprised if windows 10 didn't work on your machines, in place upgrades are hard though...

QLC flash is tricky stuff to make and use, so here's a primer

chris 143

I was wondering something similar

I guess it's possible, but then the storage capacity of the cell drops too.

If it turned out you had a very small quantity of regularly written data on a drive of mostly static data perhaps it'd allow you to squeeze a bit more endurance out of the drive, but it probably suggests that you're buying the wrong grade of flash

Not sure why I'd need that much speed

Aside from business use (which I assume due to terms and conditions won't be able to use this) I'm unsure what a home user could possibly need this for.

There can't be many services that could supply a gig of traffic in a single stream, let alone ones that you might use enough to justify the costs.

You don't need NAT for IPv6

The idea is that you use your link local address to talk to local stuff (eg the network printer)

Then your router advertises it's /64 range.

So you get two IPs

Given the expensive bit is getting it back into orbit...

Couldn't you send several rovers to different locations (probably still have to be within a few hundred miles but still, they don't have to be fast they just have to be able to run for a couple of years). Have them all arrive back to a central location. Then launch a whole range of samples back into orbit.

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
