Re: PDP Disk drive numbering

VAXes too.

It was a great scheme. It meant when you came in on a Monday morning find your terminal was dead you could wonder into the computer room, notice the red light on the first drive and the pile of paper at the back of the console teletype. Power off the Vax.

And then for the good bit, you pulled the little plastic drive number light off the first drive, slotted it into the second drive and boot up to single user mode. Back the he root FS was small enough to keep a copy on all the drives so it was easy to get the machine up far enough to start reading the backup tapes.

Re: Apple's fault

They made $24b on cables

Is this because their £20 cables are perhaps the only thing on the planet with a lower SLA than a Galileo positioning satellite system?

My youngest used to have an iPod with one of those plugs and used to go through several cables a year. All the parents I knew who's kids had iAnythings said the same. If you went to the iStore and looked at the customer feedback on the cables there were thousand and thousands of 1 star ratings and bugger all else. Maybe they've made them last longer now, he stopped using the iPod so it stopped being my problem. But I did find that the cheap knock off cables on Amazon or eBay were massively more reliable. Perhaps people take more notice of the star ratings on those sites than on Apples own site.

Re: Military Spec

I don't think they were used in tanks, they were used in large numbers by the navy. Same argument, if it's a good height for a step someone will jump on it.

I don' think the TEMPEST rules would have resulted in the thickness of the plating, thicker metal isn't usually needed to make a Faraday cage. The pico amp measurement rig I built back in the 80s had much thinner walls. The front and back of the case had plenty of holes in them. The TEMPTEST spec kit I remember working on wasn't allowed any externals wiring, everything was fibre in and out, even the 9600 baud serial connections.

Re: Military Spec

I believe that a lot of the difference you've seen is down to the shift from doing the support inhouse

It wasn't just things like support. Back at the start of the 90s I was doing a lot with Unix workstations. HP's new 700 series was popular with the military.

> unless you use toothbrush type charging its far too inefficient.

Is the charging on toothbrushes efficient?

When it comes to electric toothbrushes the usage model should be pretty simple to understand, we're all told to brush our teeth twice a day, after breakfast and then before bed. So the charging model should be pretty damn simple to understand. It should charge between the morning and evening tooth brushing session.

From the number you see in shops the Oral-B/Braun ones are the most popular.

Well they don't fully charge between sensible morning and evenings. Yeah, maybe when I start work at 00:30 and don't get to bed till 23:00 or so, but not for a normal day.

Oh and don't get me started on who in their right mind makes charging units that don't work in both the US and the rest of the world.

My old Panasonic electric razor recharges wirelessly with induction coils in under and hour.OK it has two coils but works without the peg in the middle which Oral-B uses.

Re: "It solves a problem that people have."

@R3sistance, no worries, but it isn't only the DHCP server, that was just the just app that I hit the issue on. It's anything that gets restarted when the NM finds a new device.

I know that for the certification exams these days that you need to know NM, for the Red Hat ones its hardly surprising that RH want to examine you on Red Hat's software, but even LPIC now lists NM and is threatening to stop requiring ifup/ifdown.

I've not had time to explore things at 8, if you want to use the script approach at 8 you have to install it, it isn't there by default. I've not seen what the OpenStack world is saying for 8 either.

Dazed and Confused Silver badge

Re: "It solves a problem that people have."

Sorry, you're wrong.

The problems at RHEL6 are totally different. The problem I described above is what happens at RHEL7. Go try it.

If you look at the comments I made above you'll notice that I was talking about how NM & systemd interact, does that sound like I was in "6" mode?

Dazed and Confused Silver badge

Re: "It solves a problem that people have."

One reason for hating NetworkManager is that it breaks things. When you run NM it tries to react to changes in your networking environment, this is its job. So when you create a new networked device NM wants to react. Some of these reactions can be good. So in the case I mentioned above you reload the NIC driver and NM restarts the networking on the NIC, which is nice.

But it can also do things like restart other bits of SW, for example the DHCP server. So you create a VM, it gets a vnet device for each vNIC and NM restarts the DHCP server for each of these new vnet devices. If your VM has several vNICs or you manipulate a bunch of VMs together you get a storm of network device changes and therefore a storm of restarts. At this point systemd and NM get into a punch up which results in systemd disabling the services that NM is causing to restart. As a user what you see is that when you start some VMs other random bits of SW stop running. I'm guessing this is why step one of the OpenStack installation guide say disable NM (OK I've not checked this for a a year or so, but it did the last time I checked).

NM can be great on laptops.

But I use CentOS/RHEL as a server OS and that tends to mean you use it in different ways. On a server I'm not sure of where I might want to separate a connection and a device, whereas on a laptop it is useful to be able to switch between wired and WiFi networks.

To my mind there are too many things in 7 which seem to be aimed at the destop/laptop world which are detrimental to the server world. YMMV.

But udev has been subsumed into the systemd project. It ain't part of PID 1, but they've done things to udev so that some things which worked fine in previous version no longer work in systemd-udevd.

One of the things that I don't like about systemd is that lots of things which have nothing to do with PID1 or even the general idea of an all purpose service manager have ended up inside the systemd world, udev being one such thing.

Dazed and Confused Silver badge

Re: Why do we need unit files? Parallel startup tasks.

OK, so one possible example.

In traditional Unix/Linux you list all the filesystems you want mounted at boot time in the /etc/fstab file. At some point in amongst the startup scripts someone runs a mount -a or a mountall and all your filesystems get mounted. What happens if one isn't there yet?

In the systemd view of the world early on something reads the fstab file and generates a set of mount units with a dependency on device units. When the devices are found udev processes them, in the systemd world a flag tells systemd-udevd to make a device unit associated with the device. When both the mount unit and the device unit are there the dependency is met and the filesystem gets mounted. This allows for a certain degree of asynchronous mounting if the storage devices are starting at the same time that the servers are starting.

Now, there's some dumb stuff with this, like needing to kick systemd to get it realise that the fstab file has changed.

There are lots of things I don't like about systemd. Like you I don't see the need start a lot of the services at boot time in parallel. I don't like its spreading its tentacles in every direction. But I've come to quite like the idea of having one central manager for all sorts of different services. But please for the love of all we hold precious can we not have PID 1 having such a large attack surface.

Re: Device naming

I don't think the device naming weirdness is down to systemd, that's down to the kernel initializing stuff in parallel. So if you've got multiple disk interfaces they're being enumerated at the same time, so it's anyone's guess which device will be sdWhatEver. You could see issues in pre-systemd boxes too, Linux doesn't natively have persistent device naming, hence the pre-systemd udev rules to make /dev/disk/* and the similar arrangement for tapes etc.

I must admit I've not tried changing the names of disks with systemd-udevd just used symlinks. If multiple udev rules generate the same symlink then the one which remains at the end is the last rule to fire, so you'll see this for multipathed disks is if you compare /dev/disk/by-id and /dev/disk/by-path, and RHEL7's (with systemd) and RHEL6 (without) behave the same here.

BTW, I'm not trying to defend systemd here, I've got enough gripes against it.

Dazed and Confused Silver badge

Re: "It solves a problem that people have."

> One thing I can think of that systemd does that sysv didn't is "status management"

Well, when it works it does, but :-)

So if you hate NetworkManager and want to continue to use the network service and ifup/ifdown you can disable the dreaded NM and enable network. Great. Then if a NIC goes down on you or someone does something like reloaded the NIC driver to tweak a load time param the network goes down and systemd won't bring it back up again. You can't do a systemctl start, it won't do a proper stop or a restart. You have to go in and manually cleanup before you can restart it.

Oh and of course the systemd team have subsumed udev, but they've imposed their "my way or the highway" approach so you can't just have udev do the ifdown & ifup for you as they take longer that the systemd-udev allows anything run from an action to take and even if drop them into their own process group and session it tracks them down and does a kill -9 without bothering to log anything.

I think there are some great ideas in systemd, I really do. But there is a less than stellar implementation at times.

Re: Asimov was a letcher

As for reputation, maybe he had that reputation among men in his social circle, and the women he targeted, but it's really unlikely that women in general would have been in on the loop unless they were very close to it.

Funnily we were talking about this sort of thing with my mother the other day. She'd been a nurse back at the end of the war and through in to the early 50s. She commented that there were certain doctors that everyone knew not to stand close to.

The situation with a famous author is likely different in that at a con are people around them are likely to be in a more open group, so there will be less chance for the warnings to spread.

On the other hand there might have been a groupie effect. I've no idea whether he had that effect but I've known normally sane women throw their knickers at some celeb they fancy. Yeah I thought this was a myth too, but no. The fact that some (or even many) women throw themselves at a celeb doesn't give them license to assume all women will welcome their advances.

I remember listening to the BBC series when I was young, the transistor radio hidden under the pillow I must have been 10 or 11. It had be totally hooked. A few years later I found my sister's boyfriend had the series on open real tape and I copied it. Later on they published it on cassette tape, I've still got the set somewhere. But you can now get it from various places, I've got it from Audible along with an unabridged rendition. The first two books are very close to the original, the radio adaptation of Second Foundation is much further from the original but I think I actually prefer it but that might just be because I heard that first and I'm more familiar with it.
