Linux clockpocalypse in 2038 is looming and there's no 'serious plan'

Re: The problem is in applications

There probably aren't a lot of ext3 systems around even today.

There are. ext4 is really quite bad at dealing with improper shutdown - power failure and the like. The configuration I and many others use is to create a (smallish) root filesystem with ext3, and use xfs/ext4/whatever for the other filesystems. This means that a machine can usually boot properly after a hard power-down.

Euro broadcast industry still in a fug over that 4K-ing UHD telly

Vic
Silver badge

Re: People don't want it.

4K enthusiasts can argue all they want with anecdotal evidence that they could tell the difference at 20 feet away. They really can't, it's human biology.

Your point notwithstanding. people *will* see a difference between 720, 1080, and 4K transmissions. Ands it's nothing to do with the display, for the reasons you quote.

There is a bit budget for any transmission stream. The more compression you use, the less bandwidth required - but, for any given codec, the lower the quality of the image. And so it is with broadcast - the higher resolutions are simply given more bandwidth. So the difference you will see is that the bigger-number stream has less obvious compression artefacts.

There were rumours that at least one broadcaster turned up the quantisation when HD was coming in so that the HD streams would look visibly better. I couldn't comment, opbviously...

what was RedHat's response to the latest Ghost exploit for RHEL4 boxes? We have 5000+ RHEL 5+ servers and 2-300 still running RHEL4

I don't know about RH's response - but RH aren't the only ones who can support RHEL4.

Re: from the blog ....

DAB sounds bad only because there's too many stations crammed into the available bandwidth.

Only in the very broadest sense...

DAB - not DAB+, just DAB, as we use in the UK - uses the MP2 codec, which is shite. We all complain about MP3 artefacts, but MP2 is significantly worse.

Now I *suspect* that, given enough bandwidth. you could make MP2 sound OK. But we don't have that much bandwidth available. We have enough bandwidth for AAC or MP3 - but that would mean DAB+, which we don't use.

Back seat drivers fear lead-footed autonomous cars, say boffins

Vic

Re: Roller coasters

At motorway speeds recommended distances are more to do with reaction time than actual stopping distance.

Errr - no.

Reaction times are fairly constant, so reaction distance rises linearly with speed.

Braking distance is essentially[1] proportional to energy, so rises with the square of speed.

On motorways, of course, most people are driving very much closer than their actual stopping distances, so you're relying on unusual events not occurring. That's a big part of the reason for huge pile-ups...

Re: cough @stucs

I can see why it might alleviate car sickness, and why it might not. Anyone know?

It depends on whether or not you can see a true horizon.

Travel sickness occurs when the inner ear describes one sort of motion, and the visual system another - such as when you're inside a vehicle, or when you're reading whilst moving. In evolutionary timescales, such a condition only occurred when you'd been poisoned - and the solution to that is obvious. Travel sickness is a mechanism evolved to protect you from poisoning.

So with a HUD, if you can see the outside, you'd probably get away without sickness, But I can't imagine reading would be much fun...

Re: No flaps?

I suspect you mean "Glide Slope".

Angle of Attack only really has two states - less than the critical angle, or more than the critical angle. An aerofoil with an AoA greater than the critical angle is stalled. If you didn't do that deliberately, that might well be a problem...

Re: No flaps?

To land, how does one slow to a safe speed *and* maintain safe descent rate w/o flaps?

Flapless descents are standard practice, and are a required capability for the PPL, even if you're flying an aircraft fited with flaps. They're very useful if it's a bit tubulent on approach...

This is the aircraft I've had most fun in. It has no flaps either...

Re: Carbonates are how the Earth deals with excess CO2

As long as the oxygen content remains high enough, CO2 levels pretty much doesn't matter - the lungs won't absorb it.

That's completely untrue. CO2 in the inspired gas *will* be absorbed - or at least it will prevent CO2 from the body being expelled. It's just that hypercapnia is a prefeable condition to hypoxia.

Some complain of a headache if exposed to several percent of CO2 for hours, but that may be due do other contaminates in the air

No - hypercapnia is an issue. It leads to an assortment of symptoms - the worst, IMO, being panic in hyperbaric situations. This has undoubtedly led to the deaths of quite a few divers.

Only when CO2 displaces O2 is there a real problem - but that would be true of ANYTHING.

Again - untrue. Try breathing a normoxic O2/CO2 mixture. You'll only take a couple of breaths before you get into respiratory distress[1]. It's a horrible thing to go through.

backfill the coal mines where you extracted it to begin with.

And what form are you going to use to store it? Something soluble? That'll be nice for your water table.

Vic.

[1] The urge to breathe in just about everyone[2] is driven by blood pH. CO2 in your body dissolves in the blood, leading to carbonic acid, which lowers that pH. The lower the pH, the greater the urge to breathe. Carbon dioxide is an active chemical in our lives; it would be an enormous mistake to consider it an inert gas.

[2] There are, apparently, a (very) few chronic CO2 retainers whose ability to determine blood pH has failed. I'm fairly sceptical of this, but I've not bothered to research it in detail, as it's not going to apply in the environment[3] in which I'm going to be involved...

$10,000 Ethernet cable promises BONKERS MP3 audio experience

Vic
Silver badge

how they could possibly claim Ethernet is directional, is beyond me - regardless of what data it is that's travelling down the cable - an ack needs to be sent back for every packet - making it bi-directional?

Each pair only sends data in one direction - that's why it's full-duplex; you have a separate pair for each direction of travel.

That said - current flow in each pair is *still* bi-directional...

Re: "Broadcast is efficient" Badvoc

I was refering to the fact that I am sure most streams are not 50i or 25p

Re: "Broadcast is efficient" Badvoc

Also I am sure there is temporal compression as well.

There's temporal compression on almost all forms of digital TV. Those that don't use it (e.g. MJPEG) are not useful for broadcast, as they do not achieve the compression ratios necessary to get a reasonable image quality with the data rates available.

Re: "Broadcast is efficient"

Does anyone watch the "shopping and fucking" ... channels?

Yes. People do.

QVC, for example, is one of the biggets moneyspinners in digital TV. That's why they put so much effort into making it perfect[1], even if the decoder isn't working correctly...

Vic.

[1] For example, the A/V sync is largely maintained by transmission time. So even if your PTS sync is badly broken - as it was originally in all the early Sky boxes, because it was broken in the ST reference tree - the lip sync is still pretty much there.

Plane crash blamed on in-flight SELFIES

Re: So wait

as did the loss of control and stall.

From the sound of it, he didn't just have a bit of a stall - the rate of descent implies an uncontrolled spin. Which, given the fact that he appeared to be part-way through a climbing turn when it happened is somewhat understandable.

I was reading some FAA materials on spinning[1] a few weeks back - the upshot of one report was that, if you spin at 1200ft or less, it doesn't matter who you are; you're going to crash.

Great Firewall of China blasts DDoS attacks at random IP addresses

What weak spot of the DNS system are we talking about here?

Most DNS lookups are simple UDP packets without even so much as a serial number. So a client asks the question, and accepts the answer with no way to know whether or not the response is trustworthy. Thus a bad actor can send incorrect responses and subvert the DNS system. To make matters worse, it can flood out such responses even before the question is asked...

There are ways to improve on this - but they are very far from widespread.

"Without a reboot, services using the old library will not be restarted"

That's the problem right there.

Not really - it's not actually true.

Services must be restarted, but that's a trivial matter. The machine as a whole does not need to be rebooted in the short term; this might, of course, lead to certain daemons still running the old code, but the attack surface is minimised and the public-facing services left running the patched version.

Restarting web, mail and other network services takes less than a minute all in.
