Interesting isn't it?

The very idea that a manufacturer, when told that the US is too paranoid to allow it to trade with them, can just shrug and say "OK, it's not like their important or anything"

Also interesting is that the rabid paranoia infesting the feral 'democracy' is so bad they didn't even notice this huge change in their own status.

Blackbird shot down, patent nuked by judge in Cloudflare legal battle

analyzer

No no no no, this is just soooo much bigger than that

Blackbird will have to appeal this because of this part

"The limitations [Blackbird's claims] recite generic computer, network, and internet components, none of which is inventive by itself."

This is the first challenge that has indicated the term "with a {computer|network|internet}" is no longer original and therefore invalid in a patent.

With a priority date of 1998 this ruling against this patent has the potential to invalidate every patent since then that has that disingenuous add on "with a"

This could really be huge if it survives the US appeals process.

Meltdown's Linux patches alone add big load to CPUs, and that's just one of four fixes

analyzer

Confusion reigns

It would seem that people have confused how these vulnerabilities got their names.

SPECTRE V1 and V2 are vulnerabilities that arise from issues with speculative execution and how instructions are retired. V1 is quite easy to take advantage of whereas V2 is a great deal more difficult. The chances are that if your current CPU does speculative execution then you are vulnerable to both of these.

Mitigation for these 2 vulnerabilities causes the least slowdown in operation.

MELTDOWN breaks down the isolation between user space and kernel space. So far the only *modern* processors that have been found vulnerable to this is Intels. This is the big slowdown as the only solution is to force a full context switch when moving to and from kernel space. The problem for Intel is the large number of CPU states that it takes to achieve this context switch.

For those old enough to remember WNT3.1 it was dog slow because Intel CPUs were not that fast and the device drivers were not in kernel space. The BSOD appeared from WNT3.5 onwards when device drivers were put in kernel space for speed reasons.

In general use the same always applies, it doesn't matter which CPU you use you're unlikely to push the system to the type of limits where you'll come across these slowdowns. If you do push a system that far then you will need to test under your specific use case. As always with these things not only will your mileage vary but so will your fuel consumption.

Ghost in the DCL shell: OpenVMS, touted as ultra reliable, had a local root hole for 30 years

analyzer

Re: Wasn't VMS...

No actually it wasn't.

DEC were looking to replace VMS at the time so as to cover the 32 bit VAX and 64 bit Alpha with the same OS.

Dave Cutler and his venerable team presented PRISM and the other engineering team presented OpenVMS. OpenVMS won the beauty contest and Dave was a little ticked off then Bill came along.

As a result Windows NT was actually based on PRISM not VMS because it was actually capable of 64 bit from the beginning, they just didn't have 64 bit Intelx86 at the time.

Meltdown/Spectre week three: World still knee-deep in something nasty

analyzer

Re: Intel "shouldn't be selling CPUs?"

Well that's a little more complex than the simple faster then.

It kind of goes like this, Intel CPUs are 'on average' 30% faster than AMD Zen CPUs <--- the point where idiots stop reading <--- for single threaded workloads but there are workloads where AMD is faster. For multi threaded loads, AMD Zen CPUs are on average 13% faster than Intel but there are workloads where Intel are faster. So CPU choice is pretty much irrelevant except for outliers where one will seriously trounce the other.

The curious thing regarding servers that I never see mentioned is the actual data throughput of the system containing the CPU. As the Intel Xeon sports 44 PCIe lanes vs the 128 lanes that the AMD Epyc provides and, typically, 6 PCIe lanes are dedicated to board specific functions, that leaves Intel with only 38 to play with vs AMDs 122. This would imply that the actual throughput of an Epyc based system could be far higher than a Xeon one.

Tesla reveals a less-long-legged truck, but a bigger reservation price

analyzer

Re: Electricity vs Petrol/Diesel prices

A quick search for business costs of electricity finds this

The average bill for UK business is £2,528 per year. The average unit price per kilowatt hour (kWh) is 9.50p. The average daily standing charge is 20p per day. Most businesses use between 15,000 and 25,000 kWh per year.

as opposed to the reaming the general sucker gets

Electricity is typically more than three times as expensive as natural gas – 14.37pence per kWh rather than 3.80p. It also emits nearly three times as much carbon dioxide: 0.447kg per kWh rather than 0.184kg.

So 5p per kWh difference to the good for business and nearly 3p per kWh over petrol.

1 litre of diesel-oil 10,0 kwh 35,9 mJ @120.3p/litre ( average )

at 10kWh equivalent you have 93p vs 120p.

Artics do about 41l/100km thereby costing £49.32/100km and use 410kWh which costs £38.13 in electricity. Using the usual conversion ratio for USD and GBP 1$=1£ you would need to drive 178,731 km to get the extra £20,000 back from the standard Tesla truck.

I care a great deal about when they get it right, because it is my entire work week.

We have started testing Linux based systems via HyperV because MS said that's cool and this affects my entire work week.

Companies use MS extensively, just because I think it is not fit for purpose on a personal basis does not mean that I can throw it out everywhere. So I really do care what MS do as it has a real effect on my working life.

I am sure that I am not the only person in this situation either, everybody has to pay the bills. As an aside, I have found that MS security ( server side ) is much better over the last 5 years.

As another aside, your post received not up or down vote, a reply was more in order.

What a laugh

"Our society has never had a system where evidence of criminal wrongdoing was totally impervious to detection, even when officers obtain a court-authorized warrant. But that is the world that technology companies are creating."

Just maybe it's because they snooped too much and when found out they then lied, had laws changed so it was retrospectively legal, created illegal 'accidental' monster databases etc etc etc.

Then after all that they expect people to actually trust anything they say, such as "We won't look at anything we're not supposed to"

Fresh chips from Intel (yay?) at 14nm (awww)

analyzer

I was curious about PCIe

The best Intel have is 42 PCIe lanes whereas AMD are touting 128. It's all very well having the fastest and highest number of cores on one silicon slab but at some point you have to shovel data into and out of the beast, otherwise known as throughput.

With 3 times the PCIe lanes available I don't think AMD will have to match Intel speeds or core counts to be able to best them in genuine real world environments. Until Intel add more PCIe lanes their actual throughput could easily look pretty sick against AMD.

I haven't seen a motherboard that fits out the entire 128 yet and I'm fairly sure that I don't want to see the price of a MB with 128 PCIe slots or how much to fill them all.

This is something that Intel have had no answer for and seemingly still hasn't. This reduces them to 'look how fast single thread is','look how many cores','look at the benchmarks'. "No no don't look over there that's the nasty nasty throughput thing."

Hey Intel this is called competition, you may even have to stop gouging our wallets.

Questions, questions

I'm no guru and can get stuck more often than I would like. More often then not the documentation can be a little too terse and still too often incomplete.

I find the best way to ask a question is to ask for directions to more verbose documentation describing subject BLAH as what you have found has not come down to your personal level of understanding.

Very, and I do mean very, occasionally some arse will insist you shouldn't be using BLAH software then but most people will be glad to point you in the right direction to help yourself. After that if you are still stuck then a proper description of your issue and the steps you have taken will get you far better help than the attitude a lot of people tend to have of just crying about how shit everything is.

If you are unwilling to show basic respect why would you expect to receive it?

Hmmm Tivo?

Had the old Tivo and that wasn't connected to the SuperHub it was only connected to the TV part of the cable. This is partly why the old Tivos performance was utterly carp.

The new Tivo, on the other hand is connected to both the SH and the TV cable so Netflix and iPlayer etc are fetched over the internet and is an immeasurably better experience than the old Tivo.

Having an SH 2ac I get none of the issues with the SH 3 and also full 200 down, except for really busy times when it sometimes drops to 150 so the new Tivo has always been pretty sharp in performance.

Re: Virgin Media Tivo

Virgin are being a little economical with the truth. There are 3 different hubs in use SH 2, SH 2ac and SH 3. I had an SH2 that was knackered and the visiting engineer didn't have any replacements so gave me an SH 2ac instead. It was already capable of DOCSIS3 when installed and ramped up to full speed as soon as my tiny bit of the country was enabled.

SH2 was no longer being used in new installs at that time and VM were giving new customers either an SH 2ac or SH3 as the SH 3 was still brand new and in short supply. You may still be able to get the SH 2ac, this is a NetGear based router and uses the Broadcom chipset so has been very reliable for me.

Core-blimey! Intel's Core i9 18-core monster – the numbers

analyzer

Curious

Most people seem to recognise that more cores/threads is not important above a certain number. The issue, as always, is getting enough data into and out of the CPU.

I would have thought that the deficit that Intel have regarding PCIe lanes is far more important to the high end people than actual core count. Ryzen will have 128 PCIe lanes and Intel are still stuck with 44, that amounts to a potentially huge data throughput deficit for Intel i9 processors and there is no indication from Intel that this will change.

The caveat is wait for real systems to turn up and crunch the numbers on, but on a system wide basis, it's looking far better for AMD than it has for years. Of course the system builders and MoBo manufacturers have to take advantage of those extra 84 PCIe lanes for Ryzen to really shine.

Re: Epyc 7351P @ $700

There is, currently, no information regarding in memory encryption for TR but is unlikely since as you say it's an enterprise feature.

Do we need Windows patch legislation?

analyzer

I'm no fan of Microsoft.

I haven't used MS products on a personal level for well over a decade now but the furore over this is just plain ridiculous. This has been caused by upper management not taking IT seriously at all and this is not confined to civil facilities. It should be impossible to manufacture the amount of Teflon that these people have on their shoulders. MS gave 4/5? years of warnings that XP was being deprecated and then a pay extra program that got increasingly expensive to encourage people to do the right thing and deal with the issue.

At that point upper management should have been asking about the security of their computing estate and how to guarantee its future security and providing the budget for the implementation, not stuffing their snouts in the trough until the money covered their eyes.

8 years to air-gap or secure access a critical unchangeable system is more than enough time for any properly run organisation. Upper management in this country does not meet the criteria required. MS committed to support XP Embedded systems until 2020 and these patches are a function of that.

The debacle that has occurred with XP desktop is due to idle, feckless upper management and any prosecutions should start at board level and work down.
