As it turns out, no, you can't just run an unlicensed Bitcoin money exchange

Adrian Harvey
Headmaster

Re: "No, you can't just run an unlicensed Bitcoin money exchange"

Not quite grammatical enough in your literalism - the can’t here applies to the just, not to the run alone. So he can run one, but he can’t just run one.

The reason he can’t just run one is that another thing will also happen - viz: getting collared for the crime.

Clear as mud?

Python creator Guido van Rossum sys.exit()s as language overlord

Adrian Harvey

Re: I like Python and C

“IBM, in it's infinite wisdom, decided to put the system ROM at the top of memory.”

I’m not sure the blame doesn’t sit with Intel there- the 8086 processor bootstrap begins by executing code ar FFFF:0000 - right at the end of memory (for those too young to remember segmented addressing, that’s 16 bytes shy of the 1MB highest possible address on the 20 bit address bus.). So you would have to have some ROM there to handle the bootstrap process. And putting the system ROM somewhere else in the memory map would probably have required a second chip or some custom part.

For all I know it may sit further back in computing history than that....

> This year, Iceland, the world's leading geothermal user, doubled its geothermal output to 100MW

Something is wrong with this. A small grid scale power plant is about 100 MW. New Zealand has more than 800MW operational generating capacity. Iceland has 665MW according totheir national authority. So I'm not sure that Iceland is the leader or that they're doubled output...

IPv6 growth is slowing and no one knows why. Let's see if El Reg can address what's going on

Adrian Harvey

Re: NAT required

NAT itself isn't but having clients on non reachable addresses *is*. It is because it prevents accidental exposure in a number of circumstances (Misconfigured devices acting a bridge is one example). And NAT enables that.

Analogy in video incomplete

It would have been nice if the redhat video had extended the quite nice analogy of how speculative execution works to how this vulnerability exploits it. It kind of felt like it leapt from a helpful, high-level analogy - useful for explaining an obscure subject - to "and bad people could exploit this.." It would have been helpful to have an expanded analogy that explained how the speculatively produced bill could lead to another customer receiving your order (or something)

I can't immediately think of a good way though - anyone else want to have a crack at stretching the analogy to it's limits?

Citrix snuffs Xen and NetScaler brands

Adrian Harvey
Headmaster

It’s worse than that... the original product was OEM’d so it was also called WinCenter, NTrigue, or WinDD depending who you bought it off and which extensions were bundled. You might argue that these versions weren’t Ctirix’s... but Citrix bought their code back and combined them into Metaframe.

And it was also named Metaframe XP for a while in the middle there.

So:

(WinFrame, WinDD, WinCenter, NTrigue) -> MetaFrame -> Metaframe XP -> Presentation Server -> XenApp -> Citrix Virtual Apps

Which is why everyone seems to just call it “Citrix” even though that’s the company not the product. It’s the only invariant part of the name.

Airbus plans beds in passenger plane cargo holds

Aparrently the issue is that no one has created such a scheme that can pass the required evacuation tests. A few airlines have had a go with mockups etc.

Seats in the upright position

There is one seat type not required to be returned to the upright position, and that is the Business class seats on Air New Zealand and Virgin Atlantic. They are arranged in a herringbone layout and the (fat) seat belt contains an airbag. My memory is that you can't be in the lie-flat position, (which is on the back of the flip-over seat (really!)) but I'm not a frequent flier at the front of the plane, more's the pity :-(.

I suspect the airbag is key here.

Uber self-driving car death riddle: Was LIDAR blind spot to blame?

Re: Should have seen the pedestrian

It may be harder than that to setup an OR system. Volvo’s XC90 has an partial autonomous driving system of it’s own, not just automated emergency brakes. It steers the car (in lane), recognises speed signs, maintains following distance, etc. Separating out just the one part could cause bugs of it’s own too....

Some consumer grade mesh kit can form the backhaul links over CAT5/6 (for example the TP-Link Deco range.) Don't know about the BT kit in the article though.

Tax evasion?

> but adds up to $31,000 a year, tax free.

What makes it tax free? My tax form (and I expect most other countries too). Have a box for "Other income - including tips, cash payments and profits of illegal enterprise"

Now I realise that many may not bother to pay, but that isn't quite the same as tax free.... is it? In any case in some parts the wrath of The Revenue is worse, and harder to avoid than the local law enforcement.

Pedant here....

From the article : "privately-owned equipment which the firm is unable to record or copy"

Putting on my pedantic hat here, doesn't the law only disallow equipment which is BOTH privately owned AND which the firm is unable to record or copy. In other words company owned, but the firm is unable to record is ok, as is privately owned, but recordable (say, through BYOD software add-ons)

Cool disk drive actuator pillar, Seagate – how about two of them?

Adrian Harvey
Boffin

Does HAMR / MAMR impose any limitations?

Thinking on this concept - in my crude mental model of heat assisted recording - where heat is used to reduce the coercivity of the magnetic surface material in a very narrow track so that the written track can be narrower than the write field from the magnetic part of the head - the disk will need some portion of the rotation time to cool down. If, having two sets of heads, writing neighbouring tracks, there may be some unwanted crosstalk if the track being written by the first heads hasn't cooled fully by the time It reaches the second heads writing an adjacent track.

Does that make sense? And how much of a problem would it be really? I'm not sure how much cooling is really needed... or if MAMR would offer any advantage here...

It's time to rebuild the world for robots

Adrian Harvey

We did redesign paper

I remember "computer" paper being incredibly common - you know, the stuff with holes down the side for a tractor feed system to pick it up and pull it through the printer in one continuous stream. And stuff with tear-off holes for printers where you wanted things that looked like sheets of paper afterwards.

Then we un-redesigned it.

Plants in SPAAAAAAACE are good for you

Adrian Harvey
Boffin

Re: RE: I see what you did there

The trouble with spinning to simulate gravity is that rotational inertia causes some odd effects. If you pick something up it will feel like it's being dragged sideways as it tries to remain on the same course.

It may be ok for plants as they don't move much, but for humans it's quite disconcerting. Try lifting your arm on a spinning fairground ride if you get the chance!

Why does Skype only show me from the chin down?

Adrian Harvey

Re: Ethernet fan out

I think you meant 10Base2, not T. T was for Twisted pair - just like the modern stuff...

By the way, does anyone else remember AMP taps? A kind of structured 10Base2 where a cable ran to each wall socket from the previous one, and patch cables (to use current lingo) contained 2 coax cables - one up and one back - and the plug that went into the wall socket broke the through connection and ran the signal up and back when inserted. Not cheap, but solved all those little user issues...

Novell did like to talk about that, but in practice it made little difference as the Comms links had grown sufficiently that being able to replicate over a 64kbps link wasn't really a winning feature. My experience was that the Novell protocol was much more fragile and harder to fix when it did break. I am not convinced that adding more complexity to AD would improve it. Making a GUI setting for change notification would be a plus though.

Also, using slow replication as a release mechanism is horrendous and risky. Get caught at the wrong time in the cycle and you have no protection anyway. Design a staging area or group and make changes to a copy of the GPO, then re-link to release. Or similar. There's lots of options.

IBM makes meek apology for Oz #CensusFail, offers no fail detail

Adrian Harvey

<blockquote>It's not proven yet that IBM was at fault here. This has happened before; Air New Zealand, if I remember correctly - the CEO went online blaming IBM shortly after the systems crashed, it turned out to be their own fault.</blockquote>

The company I worked for at the time was hosted in the same datacentre when that UPS failed that your talking about. We only had only one issue as for the most part our HA systems kicked in. We had our HA cluster nodes running of different UPS feeds. One system was not migrated to the cluster yet....

I'm told Air NZ had their failover/hot standby system offline at the time.

footnote: That datacentre was old, tier 1, with a history of such problems, and IBM no longer use it having built a new one of higher grade nearby.

Given that IBM have a policy of never blaming the customer as it's bad for future business with them, a bland statement like this frequently means that the customer was at the root of the issue..... Can't be sure, of course, and a train wreck like this rarely has a single cause anyway.

Patriotic Brits rush into streets to celebrate… National Cream Tea Day

Adrian Harvey
Boffin

Re: “tea before milk”.

A point of history here: Once, quality porcelain was able to withstand the shock of being filled with boiling water, but cheaper china might crack. Adding the milk first would prevent the thermal shock. Therefore if you were inclined to show off the quality and/or expense of your teacups you would put the tea in first. As a result different social sets/classes developed different tea rituals though few now know why.

iOS banking apps security still not good enough, says researcher

Adrian Harvey
Go

Re: Banking on a phone?

It varies bank by bank of course, but for my bank (ANZ) it's more secure on mobile. That's because when you initially set it up it creates secure device credentials (which you can check from the app and invalidate lost/sold/stolen devices). It is then not sending my password over the net (encrypted or not passwords shouldn't be sent - the web is leading us astray here)

Russian nuke plant operator to build on-site data centre

power plants and Datcentres

We thought about this when I worked for a power generator - but all of out plants got built in relatively out-of-the-way locations - either to make use of natural resources or because no one wants a great hulking power plant on their doorstep. It was hard enough for /us/ to get networking to our sites, diverse paths almost impossible (second cable would have to go over a mountain for one example [we used microwave for out backup path...] ) so just too hard to get the connectivity required for a real datacentre.

Microsoft points PowerShell at Penguinistas

Adrian Harvey

Re: Like grep? sed? awk?

I don't think you read the doc you link to. It's nothing like grep. It enforces the presence or absence of the lines - adding required lines if not found, deleting lines that the file must not contain.

You could do this with sed or awk, of course, but the point of this is to underly puppet/cfengine like functionality that MS is building into it's management tools. Puppet and friends are awesome products, and the model of managing configurations like software to be progressed from dev to test to production is a good step forward, but current tools are focused on devs in that they work in a programming kind of methodology and need a brain used to working with code to use well. Depending on what tools MS wrap round this engine they could address the market of admins wanting to gain the advantage of dev ops before the existing tools do.

Tax Systems: The good, the bad and the completely toot toot ding-dong loopy

Adrian Harvey
Go

Re: Jaffa cakes

No, they should start by removing all loopholes and stop using VAT as a crude luxury tax. That way they could eliminate a whole load of overhead costs (tax officials, lawyers, court cases, etc) by simplifying the system. Use the extra revenue to increase benefits and reduce lower end taxes to compensate for the increase in costs. Fairer by far as, for example, the current system charges the parents of larger kids more as they move into "adult" sizes sooner.

I'm living in NZ now where this is how it works. Rate is only 15% and government expects to run a surplus this year. A simple tax system is obviously not the only thing driving this, but I'm sure it helps.
