I see the scrote that killed Jamie Bulger has re offended. No doubt the hand wringing do gooders will be out defending him.

I few years ago I said it was a shame we couldnt transport people anymore. We could , we could send them to North Korea..

Yep, he could certainly do with transporting somewhere. No need to land the plane before he gets out, mind. >:(

This is apparently a quote from the Register’s report on this issue (but I haven't managed to find the original article).

Quote
“The fix is to separate the kernel's memory completely from user processes using what's called Kernel Page Table Isolation, or KPTI. At one point, Forcefully Unmap Complete Kernel With Interrupt Trampolines, aka oppsWIT, was mulled by the Linux kernel team, giving you an idea of how annoying this has been for the developers.”

PS the word filter rather blunts the impact of the original (but all the letters are there so you can work it out for yourselves...)

Probably this article but it's been re-written a bit since I read it the other day. ::)

http://www.theregister.co.uk/2018/01/02/intel_cpu_design_flaw/

KPTI sounds like back to the old-school way of traversing privilege levels which will presumably disable speculative execution between spaces and cause quite slow context switches instead.

Probably not a huge issue except in servers where your machine is doing mostly I/O. I suspect it will be quite a big performance hit there, though.

I'm relieved I didn't pull the trigger on that big PC upgrade when I was in Novatech pre-christmas buying Mrs. KW's present. ;D

Mine are about as much use as a candle currently, so hoping they are OK at MOT (or that the new adjusters arrive so I have the confidence to fiddle). Oh, and I'd probably better polish up the lenses, again. Seems to become an annual thing once you've done it once. >:(

Yes, as long as the fan inlets are filtered, I'm sure it's fine.  :y

If not, the whole thing'll probably fill with dust eventually, like my PC does once a year or so. ;D

My 3.2 originally had a 65 Ah battery. I ended up with a 70Ah Yuasa one from CAF for sub-£100.
Aren't they part of euroshite now (via Andrew Page)?
Yes, probably already were when I bought my battery, TBH.

Blokes there are still the same, and couldn't be more helpful, so I still go there as it's close to the orifice.

She also told me they had four Ambulances sat outside which could go nowhere as they had three drunks and a druggy in them, none needed urgent attention and had been sent as the local cops no longer drop you in a cell until you sober up/come down.

This sort of thing makes me fume. It strikes me that a fully quipped and manned ambulance costs a bit more per hour then a cold Police cell, and has the potential to be saving lives instead, yet the Police have elected to effectively pass it onto the NHS. ::) About time we had some joined-up thinking going on in public services.

The issues will be worked around in software and will probably amount to some optimisations being turned off on the affected CPUs.

This will cause a performance hit, but probably not enough to really bother the average home user.

Personally I don't think car covers are needed, especially in a garage. You need to let the car 'breath' with some air rotation, the cover will just block everything. Being in a garage it's protected from the elements, so not really needed in my view.
Those cars that are left to ‘breathe’ in barns don’t fare too well.  ;D

Assuming the roof doesn't leak and the floor doesn't flood, ventilation is required to keep something dry in an unheated building. A car in a ventilated barn will get damp, because, often there'll be a spell of very cold dry weather followed by milder damp weather. Damp air gets into the barn and the moisture condenses on the car which has been cooled below the dew point. You are relying on ventilation to take the moisture away again when the dew point rises.

Covering the car is a tradeoff between inevitably slowing this process by interfering with the ventilation and preventing dust, bird poop, etc. settling on the car.

There's no right or wrong answer. You just have to decide based on the environment what's best. Make sure the cover is of a breathable material, though.

I very much like our local GP's system, you call up in a morning, they assess you over the phone, either give you an appointment of tell you to buzz off to the pharmacy. Funnily enough, when I had a rash, fever and had just got off a plane from china, I didn't have to wait "we can see you in 30mins, but if you start to feel worse come immediately".

Under the system most GP's operate, I'd have been another one in A&E (as it turned out I had cellulitis and needed treatment reasonably urgently) who could have avoided being there.

Yep, my GP is similarly excellent. I have nothing but praise for them.

It's a lottery depending on whether you have a surgery who are proactive in giving the best care possible given their constraints or "because we've all ways done it this way".

One think that might be an issue with powder coating is that it's brittle, so an item like a wishbone will pick up stone chips very quickly. I think they'd need a coat of stone chip paint on top to last, which then calls into question the value of powder coating them at all. ;)

- The working car I have now (2001 Cadillac Catera Sports) is using fully synthetic oil per th elast owner. Any good recommendations if I should be using fully synthetic 0W40 or any other grade Synthetic.

I would say, given your climate, a decent quality 0W30 or 0W40 synthetic oil would be a good idea. 10W40 semi synth is a common recommendation in the UK but we don't know the meaning of "cold start". ;)
No need to pay a premium for "boutique" oil, though.
Regular changes are a good idea. I'm not sure what change intervals were specified in Canada, but, with synthetic oil, I'd be changing it every 6-8k miles here rather than the comedy 20,000 mile interval specified by GM.

- Any specific areas for care and cleaning that I should watch for beyond oil changes and air filters for my working Catera.

The crankcase breather system has a tendency to block, so it is important that this is checked with every oil change, especially in cold weather.
Scuttle drain, of course.
Rear wheel arches and the seal by the back doors always seems to attract crud like a magnet. I'm sure you know most of this already!
Quote

- I got only one Key and one FOB opener with the replacement Catera; how can create a second spear Fob and key economically?

If you keep the fobs and immobiliser chips from your old car, you could probably have them programmed to your new one if they are the same type, then just get a new key blank cut. This is where distance is an issue, as there are several of us with Tech2s in the UK who could do this cheaply.
Quote

- Any ideas on which part(s) I should try to keep for spare from the dead Catera before getting rid of it for scrapping.

This is where you need your crystal ball. ;) You can guarantee that anything you throw away will fail on your new car the next week.  :D

Glad to hear that you've remained an OmegaCateraowner and I hope your new steed serves you well.

Just hold on to the evidence you have and ignore it. I'd say it's unlikely that you'll hear any more once they realise you aren't going to cave in.

The thing is, we accept that the M6 will be carnage at 4:30 on a Friday afternoon, or that McDonalds won't exactly offer "fast food" when a footy match has just kicked out, yet here we are, the week after the Christmas binge when everybody has been over-doing it and too busy scarfing mince pies and sherry to attend to their healthcare, it's the start of the flu season, the darkest time of the year on the roads, the coldest and the most depressing time of year to boot.

Suddenly it's a "crisis" because the hospitals are a bit busy.

Surely that just demonstrates that the system is working at its capacity, as does any optimally resourced system at busy times. I'm sure we could have a system where everybody gets seen within 5 minutes at all times, but that would entail paying hospitals to sit idle at most other times of the year. We wouldn't stomach the taxes to pay for that, though, just as we wouldn't pay for another half a dozen lanes on the M6 so it never gets busy.

I don't doubt that the NHS could be more efficient, but that's another issue. Until I hear reports of people losing their lives due to the "crisis", then it's not one, IMHO.

Yep, I would have thought you'd be able to bolt on the old ball joints. They certainly won't take well to being in a powdercoating oven, and, actually, I've used the bottom ball joints from cheap wishbones without any problems.

I also agree that the bushes are worth doing, and definitely polybush the front one.

For other parts that are just bolt-on replacements, I wouldn't bother.

I just seem to be in a position at the moment where only a few of my original suspension parts have required replacement, at 216k miles and 15 years old, yet any replacement parts seem to last a year or two. I've had several sets of drop links last a year at most (Meyle HD on now, and lasting better), I have a B4 that's leaking after a year, etc.. It speaks volumes about the difference in quality between what was factory fitted and everything available in the aftermarket.
