Re: shocked, shocked!

> I'm sure Woodgate and Clark Ltd were shocked, shocked!, to learn of such heinous crimes by the PI's they hired.

The firm's director, Michael Woodgate, was found guilty of two counts

Let's just hope that the sentence is custodial. A fine, which is bound to be smaller than the profit of rogue trading, just isn't sufficient incentive to behave well.

Re: pron on the cp

mentioned thousands of files, over a time period of months, with timestamps indicating porn browsing sessions lasting several hours, interspersed with him sending and receiving emails and reviewing documents.

Once the dodgy link has been followed or the maliciously crafted page has been viewed it can keep updating so can result in many accesses spread over the time the page is open which can easily show the accesses interspersed with genuine work activities.

You're probably right, he may well not be telling the whole truth, but this isn't evidence.

pron on the cp

It's new worthy because in any other job, if caught with porn on his computer he'd have been fired.

having porn on your pc (or if it's pron presumably it's on your cp) is not reasonable proof that you've been looking at porn.

As others have pointed out, a dodgy link could have done it, crap settings on an email client (this was years back remember). Or a malicious web-admin could easily to give them to you as a present. If I have a website which the bods from Westminster access for what ever reasons it is trivial to feed them lots of links to thumbnails (coz they download quickly so probably won't be noticed) and you just display them as 1x1 pixels dots on the screen... or similarly hide them. I could easily target these at specific IP addresses or users etc.

If you want proof you should need to more than someone saying I saw it in the guy's browser history.

Otherwise any web admin can take you down any time they like.

Some 'security people are f*cking morons' says Linus Torvalds

Re: Userland

I know you marked this as a joke, but

> The only userland event that should cause a panic is PID 1 existing.

But only if it's SystemD. SysVInit should be allowed to continue as normal

This is one of the issues with systemd, the traditional init was a very simple thing and as such incredibly unlikely to die. Once it had launched the system it became the catcher of orphans, it issues the wait(2) calls to allow them to be reaped. The kernel needs to have somewhere to pass orphan processes, this is why it panics if PID 1 dies.

IMHO systemd does too much, it has too many interaction points and therefore is much more likely to have defects and therefore at risk of dying. Unlike other userland processes, the death of PID 1 is fatal. So things which are perfectly acceptable in other process are not in tolerable in PID 1.

Re: Userland

> A kernel detecting an illegal permission escalation attempt deciding to kernel panic?

No, the correct behaviour is not to allow the permission escalation, if it is via a system call then the call should fail and return -1 and set the ERRNO. If the issue was via an attempted memory access the caller should be killed via the appropriate signal.

The kernel should only panic when the kernel has a problem, normally when it detects some sort of internal inconsistency.

The only userland event that should cause a panic is PID 1 existing.

Am I missing something or is there something wrong here?

The Samsung drive has a higher random read IOPS rating than the P4800X, but it has an even larger advantage in random write IOPS, which is emphasised in the sequential read/write bandwidth numbers where it is two and a half to three times better.

Yet the table shows P4800X read & write rate as 550K & read bandwidth of 11.2 while write is 8GB/s

Then shows the SZ985 having 750K reads/s but only 170K writes/s and bandwidth figures of 3.2GB/s for both reads and writes.

Our useless revenue service should do the same. Any profit made by multi-nationals in the UK should be taxed in the UK, they can then have a certificate for that tax which they can then use to avoid double taxation in their chosen tax haven.

The photos I've seen of this new iPhone don't look like the screen really is edge to edge, there's loads of space around the edge, at least a mm or 2. To me, edge to edge means that if a mate an I put our phones down side by side there should be no discernable gap and that it won't be long until an app arrives that lets us treat the pair of phones as a single bigger screen, or put several down together to get a much bigger one to watch movies on.

Re: Witholding tax

> They WANT to cheat, can AFFORD to do so

That's the whole idea, the tax certificate you could obtain from them would be low, so you'd only be able to write off a low amount in a higher tax location.

Only if you could provide evidence that you'd somehow run up huge expenses in a "cheating" country would you be able to avoid the tax in the higher one.

I guess it would depend on just how a company would be expected to prove it's costs.

Witholding tax

When I do business in, say, India. I have to pay Indian tax on my fees, I then get a certificate from the Indian tax man to effect that I've paid this much tax which I can then in effect pass on to the UK taxman so I don't get taxed twice. But it does mean that I pay tax at the higher of the 2 rates rather than the lower of the 2.

It surely can't be beyond the whit of the taxation departments of the national governments to come up with a scheme like this which applies more generally to businesses. This way if an international company has sales of say 1Billion in Hightax Land and then says, well yes we sold a Billion, but that's not profit because we have to pay 99.99% of that to our head office in Lowtax Land, then they'd be able to take their tax certificate from Lowtax land, which says we've paid 3p and they'd be able to deduct the 3p from the normal 20ish% of 1Billion. OK, I know that's ridiculously simplistic, you'd need to be able to chase the costs right the way through, but the assumption would that you can deduct cost but only if you could prove where they come from and prove that someone paid some tax on them somewhere. And that within your group you'd pay tax at the higher of the rates between where you sold it and where you normally do you accounting.

I know that this isn't really about the HS bit, it's about adding capacity, but I'd still argue that adding digital capacity to the country would be a better investment and help more people more of the time. We can't spend the money twice so I'd just suggesting we invest in 21st century capacity rather than 19th century capacity. In an ideal world we'd do both, but HS2 would be tunnelled for most of it's length, We don't however live in an ideal world so choices need to be made.

Re: Happy place (off topic)

I too prefer CentOS, as long as I'm allowed to stay with 6.X then I much prefer the anaconda installer, it does a good job working with servers with mixed disk technologies and setting up multipathing automatically. The RHEL7 anaconda installer isn't as good, The SLES 11 installer is pretty but has a habit of installing the OS on one disk and grub on another and is a pain to control just where grub will end up and the drive order definition, SLES12's installer has abandoned leaving you a nice autoyast.xml file and also stopped using the same UI for the installer and as the autoyast editor which I always thought was the best bit of SUSE. The Debian installer can be a total PITA on servers with different disks attached, I usually end up out at the shell to work out what's going on, thank the lords of the kernel for /sys. Preseeding would be much improved if there was any documentation worth the name, the installer saved a preseeding file for what you've just done and if they'd damn well read the preseeding file at the start of the install so you didn't have to pass options in through the commandline. ARGH!

Re: contention ratios

Thanks Mad,

What I had been musing on was what the total bandwidth of a 3G or 4G cell is, Speed testing my backup mobile hotspot I get about 35Mb/s, but when I do that it doesn't impact my kids streaming full HD video on their phones, neither does their activity impact my speed test, so I can see that the local 4G cell has a total bandwidth available of more than 35Mb/s, in fact I can test from both my phone and my hotspot at the same time, without them impacting each other.

I just wasn't sure what the total bandwidth available is.

> The only answer is to open up more bandwidth to enable more channels etc.

I'm pretty sure that there just isn't enough spectrum to cope with all conceivable comms traffic unless we start using gamma rays and the like :-).

As you say fibre gives you you're only private channel so that you don't need to compete with anyone else over that part of the link. Upstream then you'll be sharing bandwidth with others coming through the same bits of kit. Ultimately if you all want to hit the same website, then they might have a finite amount of bandwidth. There are always limits somewhere.

Agreed. Was stood on top of Lanrigg Fell on sunday with full 3G good enough for video calls.

However. When BT/OpenRetch screw up the link and everyone in my area jumps onto their mobiles then the performance sucks big time. I don't know what the full bandwidth potential of a 3G or 4G cell is, but it isn't enough when a lot of people want to use it at the same time.

Linus Torvalds may have damned systemd with faint praise

Dazed and Confused

Re: Where is the faster bootup time?

> I have thousands of servers running CentOS6 and CentOS7. The boot times are identical.

systemd is supposed to give faster boot times by allowing some start up operations to be performed in parallel. That's the theory.

But then they go an make RHEL7 do more at startup so they can loose the advantages that systemd was trying to achieve.

A great example of this is when you boot a server with several LAN cards in for installation. The new startup wants to DHCP each NIC but doesn't do it in parallel and has a hard codes 1 minute timeout. So if you got a server with a shed load of NICs which aren't on a network which offers DHCP then the boot takes bloody ages. Of course there is an option to say you only want to use a particular NIC and control how it will be configured, but it isn't always easy to determine what it will be called.

Anyway the theory is that systemd allows things like services to be started in parallel, but the practice and the theory are two very different things.

Re: replacing init with something "sane"

systemd was a good idea.

Well, part of it.

Replace the init system with something sane, that allows all kinds of extra features, automated startup dependencies, etc. Hell, even replacing scripts with a real program isn't actually that insane in the modern world.

I would argue that it wasn't "init" that needed replacing, it was "rc".

init is supposed to be the initial launcher (a minor task IMHO, it's eons since we all used serial lines and needed respawning for our getty's) and then it is is the catcher for orphans. The kernel needs somewhere to put them and so the kernel is very attached to PID 1, this is init's job. Since the kernel needs PID 1 to be there it will panic if PID 1 dies.

This is where systemd is going wrong. It is placing something far to complicated inside this orphan catcher.

The other problem with systemd is that they've not define limits on what it is trying to achieve. So it grows off in all sorts of directions. Why does the launcher also want to be the logging system?

I would also argue that launching services at startup from scripts is a better way than launching from inside a "compiled" program. It encourages the developers to make sure everything can be done easily from the command line. It also makes it trivial for admins to see what is supposed to have happened, 30 years ago no one would have dreamt of trying to administer a Unix machine without being a C programmer, for the last 20+ years that's not been the case. But even if the admins can understand the C or other compiled language they can't just walk through the steps by hand.

As someone put in a message a short while back "Don't do anything in C that you could have done in a script".

Personally I'm really not convinced that for most users the boot up speed is a killer. I usually use Linux as a server OS, Red Hat 7 has systemd in "Enterprise" Linux which is mostly used as a server OS and here boot speed isn't a big issue, especially when the POST might take 20+minutes by the time you've got a sensible amount of RAM on board.

So regardless of what is driving the "rc" mechanism I want to see the services started from scripts please.
