Re: Filters or just control

Because we don't have to prove wrongdoing, or intent of wrongdoing, the mere possibility that you might do wrong is enough in this country. It would also allow for stop and search on a flight paths, i.e. virtually all of London, to see if anyone has a laser pointer in their possession as soon as there is a report of one being used.

If you can come up with any legitimate reason for someone to be walking around the streets with a high-powered laser on them then I'd be interested to hear it.

Why do cockpits even have windows that can be got at from the ground? Aren't the instruments inherently better than a pilot's senses? Isn't this the kind of low tech, easily fixable hole that made 9/11 serious enough to justify invading foreign countries and shredding people's rights?

Seriously?

You sound like you want the aircraft industry to completely re-design and rebuild every aircraft, and for every pilot to be extensively re-trained just to satisfy some weird self righteous notion you have.

What a brilliant idea! So in the crowded sky over an airport, they want to introduce one of the largest Birds-Of-Prey.

I can see at least 2 problems:

1/ It's a big wild bird - what happens if it gets in the way of an airliner?

2/ It's a big Bird-Of-Prey. What are the local bird populations going to do? Panic, and fly away in great flocks, probably into the path of an aircraft.

Health Secretary promises NHS £4.2bn to go 'digital'

Alister Silver badge

The NHS is big enough that providers would switch over and follow the new rules even if they did kick up a stink at first. I'm really surprised how much the NHS doesn't throw it's considerable weight around.

But that's the problem,the UK government (and not just the present one but all of them since Trusts were introduced) have insisted that NHS Trusts should be as far as possible autonomous, (but with Central Government oversight) and therefore they don't have a cohesive purchasing policy, there is no functional central purchasing authority for providers to deal with.

Alister Silver badge

4.2 billion could clear the debt of the NHS, it could actually pay people what they need (nurses get a pay rise) it could allow Ambulance trusts to upgrade their fleet and not rely on auxiliaries.

Whilst I agree with you main points, I'm afraid that 4.2billion is nothing like enough to get the NHS back to a fully functioning condition. Successive governments of all colours have systematically thrown away the assets needed to maintain the service in an effort to achieve "efficiency".

Unfortunately, efficiency and good patient care are not always compatible.

It may not be efficient to have lots of local hospitals with respite beds, but suddenly, when you get rid of them all, you find that the big central hospitals don't have anywhere to discharge their patients to.

It is not efficient to have lots of Ambulance stations around a rural county, but if you close them, you suddenly find it takes a long time for Ambulances to get to the patient, especially in bad weather, because the vehicles are having to travel 30 miles instead of 3.

It is not efficient to have A&E departments in local cottage hospitals, but the alternative is long journeys for every patient to distant central hospitals, and Ambulance vehicles tied up with one patient for over an hour or more, even for minor injuries.

Pah, I really shouldn't get involved in these threads, my blood pressure goes up too much.

SQL Server 2014 memory allocation

Reading the blog here:

https://blogs.msdn.microsoft.com/bharry/2016/02/05/vs-team-services-incidents-on-feb-3-4/

It appears there is a serious bug in SQL Server 2014.

In the SQL Server 2014 query optimizer they made significant changes to the cardinality estimation. I’m sure they were improvements but not for this query. The cardinality estimation was used to estimate a memory grant for the query (SQL preallocates memory for queries to avoid spills to disk, which are big performance problems and additional memory allocations, which create the possibility for deadlocks. The cardinality estimate is an important input into the memory request).

In this query, the memory grant estimation shot up from something pretty small to 3.5GB. Given that the server only has 48GB, that meant that it could run very few of these queries before it ran out of memory, causing every query in the system to back up and, essentially, serialize. That caused a traffic jam and resulted in so many of our customer requests timing out/failing.

The ultimate resolution, for now, is that we added a hint to the query that tells the query optimizer the maximum memory grant to use for the query. It’s expressed in % of memory and, for simplicity’s sake, we set it to 1% of the memory available for this (or more on the order of 160MB). That was enough to unclog the system and allow everything to flow freely.

It is not clear from the blog whether this is a custom version of SQL Server 2014 used internally by Microsoft, or whether it is the production release. If it is the latter, then anyone running SQL Server 2014 in SQL Server 2014 compatibility mode is likely to suffer issues with massive over-allocation of memory to queries and stored procs.

Maybe El Reg can clarify this?

That's cute, Germany – China shows the world how fusion is done

Alister Silver badge

During the experiment, sensors recorded the plasma's temperature at 50 million degrees Celsius (90 million degrees Fahrenheit). That's more than three times as hot as the core of the sun, which NASA estimates is a toasty 15 million degrees Celsius (27 million degrees Fahrenheit) – although the outer atmosphere of the sun is much, much hotter.

Please forgive what may be a stupid question, but why is it necessary to create temperatures hotter than the Sun's core? I would have thought that one of the goals of fusion experiments would be to create self-sustaining plasma at the lowest possible temperatures.

Is it the case that the lack of an equivalent to the gravity conditions at the Sun's core mean that we have to create higher temperatures to get the plasma to form?

Ah right, thanks very much for the info, I didn't know that that was how it worked.

Re: Horsefeathers -- was it a DDOS or a failed upgrade?

It wasn't a DDOS.

Not unless a DDOS can suddenly cause the BT network to be handing out non-routable addresses to customer equipment, which is what I saw happening last night to our business ADSL links.

Our router/modems were being assigned addresses in the 172.16.0.0/12 subnet on their WAN interfaces, for a few hours, then suddenly they were assigned proper BT external addresses, and away we went.

Re: "The author who coined the terms robotics and positronics"

Check the etymology of "robot". It was Karel Čapek's brother, not Asimov who coined it.

The word robot simply means slave in Czech and it was part of the title of Čapek's play in the original language. It then entered the English language as a name for mechanical humanoids.

The word robotics, to describe the science of robot construction and development, was most definitely coined by Asimov.

Land Rover Defender dies: Production finally halted by EU rules

Alister Silver badge

I sort of understand the reasons for stopping production, although I do feel the vehicle has been let down by lack of investment, and particularly lack of any sales tactics at all.

What I don't understand is Tata/JLR's stated intent to produce a "New" Defender which is not going to be aimed at the commercial vehicle market, but rather will be yet another SUV.

Tata/JLR already produce 6 different models of SUV:

Evoque

Freelander

Discovery Sport

Discovery

Range Rover Sport

Range Rover

Why on earth do they think that the market will sustain another one?

Every sub-atomic particle has an antimatter companion that is virtually identical to itself, but with the opposite charge. When a particle and its antiparticle meet, they annihilate each other while releasing a huge amount of energy that could be used for propulsion. However, we currently cannot produce and store enough antimatter for this to work.

What you need are Dilithium crystals, they can contain and control matter / antimatter reactions.

Zero Tolerance

I was amused to read (on the BBC News report of this incident) that Wipo have apparently released a statement saying the Indian company has a "zero tolerance" policy on data theft.

Which is good to know, Isn't it?

I mean, what if they only had a 10% tolerance policy on data theft - would this mean you could keep 10% of what you steal, or that they only punish 90% of the staff who steal data?

Stupid bloody statement, really.

Is hybrid cloud fundamental for your organisation? Tell us, readers!

Alister Silver badge

is hybrid cloud a fundamental for your organisation?

"The cloud" is really just marketing speak for hosting software on someone else's hardware, and in that sense then yes, it's a fundamental part of our organisation.

Most of our server estate sits as VMs on privately hosted virtual environments in various datacenters run by various suppliers.

The things we retain as on-premises are what's needed to make the office work, so we have Active Directory DCs, Exchange servers, file servers, and software repositories as either physical or virtual machines hosted in our own buildings.

Does this count as "hybrid cloud"?

I doubt it.

Alister Silver badge

747 started out as cargo aeroplane, but then they thought how many passengers they could get onboard. Blame, or cheer, Juan Trippe.

Sorry Graeme but this just isn't true.

In the early 1960s Juan Trippe was pushing Boeing to provide him with a passenger aircraft with twice the capacity of the 707. Joe Sutter was transferred from work on the 737 to design a passenger aircraft that would fulfil Trippe's wishes.

However, it is quite true that from the outset the aircraft was designed so that it would be convertible to a cargo aircraft with a nose-loading door, should it be required.
