Fedora 21: Linux fans will LOVE it - after the install woes

Brian Morrison

Re: Minimal install

I'm really happy with it, feels a lot more slick than F20 did.

My only problem was that fedup wouldn't get as far as actually running the update, fixed that by using fedora-upgrade instead.

Re: Why install when it's going to be obsolete in a few months?

You could take that approach but, with a couple of minor exceptions which took at most a couple of hours to fix, I have been using Fedora since about FC3 or 4 and upgrading it along the way. It's good enough for what I do with it (everything at home) and I see no reason to change.

Re: tom dial @chris lively

To be honest Matt, I am unsurprised by these sorts of decision. The real question we should be asking is "Are the laws that underlie these powers reasonable where the ability to compromise communications of those in legitimate surveillance also means that all those communications from people that are not targets of surveillance should remain entirely obscured and not made vulnerable as a consequence of legitimate operations?". That's a much more pertinent question to my mind.

Hi-torque tank engines: EXTREME car hacking with The Register

Re: Oil system?

And yet the Concorde hydraulic system, using enormously expensive M2V fluid, managed not to leak despite some joints being of a sliding type and operating at 4,000psi.

Tornados have thrust reversers, which is why the fin always gets sooty.

Re: No...

Yes, it's the idler gear for reverse together with the corresponding main and layshaft gears that are straight cut.

Straight cut gears also led to the demise of Bristol Britannia prototype G-ALRX that was crash landed on the Severn mud flats after the straight cut reduction gear started vibration at the natural tooth frequency and broke up, the engine accelerated with no load and the resulting turbine failure set fire to the oil tank in the wing.

Re: Car Hacking

A friend of mine has a couple of Meteor engines in one of his garages, one is totally knackered (holes in every piece of crankcase mainly) but the other is a runner. So one fine day he decided to start it just to see what happened.

The engine has not exhaust stubs, or indeed anything much, but he thought that with the aid of a 12V battery he could probably get it to turn over and fire. Well, actually no he couldn't, the battery voltage is just too low so nothing much happened. But the trying meant that a fair bit of fuel ended up in the float chambers, induction manifold and, well, just about everywhere really.

Another friend arrived, and as these things do it transpired that he couldn't wait to get his car battery out and put it in series with the original. This was duly done. The starter was engaged, the engine fired, and ran for about 15 seconds. During this time it made a massive amount of noise, emitted 2 foot long flames out of the exhausts, blew stuff around the garage and damn nearly deafended the pair of them.

Bloody good fun! Bit they were almost into cacking territory...

Re: We need the tainted evidence laws of civilized countries

Exactly this!

While the data may not have been obtained through a criminal act (it may just have been negligent) it seems extraordinary that anything obtained by accident can still be processed and used.

If anyone wonders how it is that GCHQ and friends are using bulk intercept data within a strict legal framework, this tells you that while the framework may be strictly adhered to the underlying law is really rather wide and very lax in its approach to privacy.

Antares apocalypse: Orbital points finger at turbopump FAIL

Brian Morrison
Bronze badge

Re: Turbo pumps

The Engines that came in from the Cold I think it was called.

Most closed-cycle (turbopump exhaust fed into combustion chamber) engines run the turbopump fuel-rich which gives lower pressures and temperatures. The NK33 does the opposite by running the turbopump oxidizer-rich. The result is high specific impulse engines where any kind of small problem with the turbopump operation can lead to the steel casing of the pump melting and burning through in roughly 100ms. The casing is roughly an inch thick piece of very tough hardened steel.

Re: In this case, it's not the technology.

There can be lots of causes of turbopump failure, but the NK33 is particularly vulnerable because to get its high specific impulse it puts O2-rich turbopump exhaust into the combustion chamber. That means that if anything goes wrong with the flow of the very-hot gas/liquid exhaust flow the turbopump casing can burn through in a small fraction of a second leading to catastrophic thrust reduction and probably an explosion of the remaining fuel/oxidizer.

Re: The country

It's worse than that.

Similar thing happened locally, and being a techy I was asked to explain to the antis all about the benefits of having a base station locally. This was in a pub, fortunately.

I started off by explaining about radio wave propagation. Within a few seconds a lady piped up "But it's a phone, not a radio!" "No, it uses radio to transmit the signals needed to carry the voices" I said. "Oh, so that's why I get the nice lady that sounds just like the one on Radio 4" she said.

I settled for a couple of pints in the end.

Re: Multiplicative capabilities

"You will not be beaten or murdered for exposing corruption in London city hall"

No, you won't, but you will be maliciously prosecuted for consensual sexual activities which are classed as likely to lead to harm to the genitals by a government expert witness and also be charged with extreme porn offences and have your reputation dragged through the mud and the tabloids. Ask Simon Walsh. His mistake? Questioning City of London police over corruption that he became aware of in his day jobs as a barrister, alderman and magistrate. And those offences were dragged up in forensic detail only after the police failed to find any evidence of him being part of a child porn ring. He was acquitted because fortunately there are people who specialise in protecting the unfortunate against such fishing expeditions.

Re: Raise your hand....

Let's not forget that the gubmint is currently trying to remove all 3 of the things we rely on to try and keep some sort of popular control over the state's power.

They are:

1) Trying to limit Human Rights legislation

2) Trying to heavily restrict legal aid

3) Trying to prevent access to Judicial Review

In the latter case the Lords have just voted the government amendments down 3 times but I'm sure the slavering maniacs will be back with more ordure-soaked stupidity soon.

The price of freedom really is eternal vigilance, and even that is no guarantee.

Re: just like the good old days.

The big difference with these NK33 closed cycle engines (like the Rocketdyne F1 and the SSME the turbopump exhaust reenters the combustion chamber) is that they run the turbopump oxidiser rich rather than fuel rich. This is much more efficient, but it has a side-effect that the turbopump casing can burn through very rapidly if something goes wrong. 1" of hardened steel lasts less than 100ms in these cases...

Re: Get a grip people...

I agree that it would be good to get poorly-performing stuff that misrepresents itself as a well-trusted part out of the market, but given the level at which these counterfeit parts live (several layers below the people who put their label on the box) then it's a lot easier said than done.

Causing a work->doesn't work regression is not acceptable, as explained frequently by Linus every new kernel release.

Re: @Andy Prough Hostile leadership vs hostile software

Which is a workable desktop environment for most people that do. I've used it for years, I never got on with KDE and haven't been able to live with Mate or Cinnamon (although I did try for quite a while).

Re: @Andy Prough - Hostile leadership vs hostile software

I wouldn't expect a server to have any of this stuff on it, it's used for workstations (although my own machines with pulseaudio and systemd do a bit of serving for IMAP etc) and that's where it is useful.

What I don't do is claim to understand it all fully or want anyone else to do something they don't want to, my view is that systemd should be configurable to be as minimal as possible or even be removed in cases where it provides no useful benefits.

Re: Oh please...

I've seen some of the complaints about systemd on the kernel list, the one in particular I remember was the one about the debug argument and I agree that it seemed pretty odd although I believe that someone patched it up to work properly after this. This was a Kay Sievers issue as well wasn't it?

There's no question that LP is very much a marmite issue to some people, possibly quite a lot of people. I wonder if he's just bad at explaining himself. I've read some of his blog, it didn't seem particularly obtuse but clearly he's a man on some sort of mission.

Re: Oh please...

And yet, I use Fedora with systemd and pulseaudio. The latter is great for my purposes, I've had no trouble with it since Fedora 10 or so. Systemd? Well, it seems to work well for my needs, I only had one problem with a SpamAssassin update where I was trying to use -d as a spamd option without realising that systemd works a little differently.

Personally I don't understand the total dislike for it that some people have but then I am quite happy to see people build distros that use SysVinit if that's what they want. There is room for both camps.

I thought you were out by a fair bit, I made it 3.334x10^^17 molecules in 1/100th of a cubic mm. 100 quadrillion is 10^^20. Er, no, quadrillion is 10^^15 isn't it, I was thinking 10^^18 which is a quintillion. So it's actually 3.334x10^^14. Was that the number you first thought of?

18g (or cc) of water gives 6.022 x 10^^23 molecules, so divide by 18,000*100,000.

Galileo! Galileo. Galileo! Galileo frigged-LEO: Easy come, easy go. Little high, little low

Brian Morrison

Re: what is their current orbit?

I don't think station keeping is much of a problem, it's not like geostationary orbit where they need to be within a small box over the equator as they are actually intended to be in a geosynchronous orbit (2 orbits in 24 hours is what the GPS SVs do, not sure if Galileo is the same).

In theory all that matters is that they are in a predictable position, fill in an empty part of the constellation and can be found and their ephemeris data measured very accurately using the earth stations, the satellites just send this information back to the GNSS receivers of the users which then perform the calculations needed to locate themselves.

It should be identical in terms of everything within O2's network with the exception of the specific virtual links allocated to the MVNO in question and any interaction between the MVNO's billing system and the O2 HLR that holds the account details/credit status.

Short answer, very little difference, but I can say that in giffgaff's case their data links are pretty congested and they're in the process of making changes to tariffs etc to try and fix this.

Re: Doppler Shift and Timing of Satellite Signals

Read the ATSB report, there are two or three examples of other commercial flights being tracked using the same Inmarsat systems and their ground tracks being plotted within a quite small error in comparison with their position recorded from GPS coordinates. That should mean that data captured from the MH370 aircraft is valid and relatively accurate.

Re: What about those black-box locator pings?

The problem is that the pings can change frequency as the batteries run down, it is quite easy for a 37.5kHz pinger to drift down to 33kHz once the batteries are nearly dead. In addition the water pressure also affects the frequency a little, so the frequency can change depending on the depth.
