Not if you've got a nice tidy datacentre. The screen and keyboard are there in the form of a KVM switch. Or you use the remote lights out functions.
Personally I'd provide remote lights out and a KVM on a trolley rather than a permanently wired switched one, but people do want the latter sometimes.
It's mostly used for upgrades, whether it be firmware or hypervisor, and when there are hardware problems - if you have enough servers, you do get hardware problems.
Well yes. But the thread was about domestic KVM originally, where it makes no sense, which is what I said, and it drifted to 'or on a data center' where I pointed out it makes no sense either in the context of what was said - hooking up lots of boxes running one operating system each.
That doesn't mean lots of boxes running one operating system each - it allows for both non-virtual servers and hypervisors. I was careful to use the words "physical" and "hosts" - when you're dealing with VMs and hosts that's how you differentiate between them.
As I said, the sensible approach would have been to say "ok, there is a point to KVMs". But you'd rather wriggle. You're still doing it. It would serve you better to accept the exception and stop arguing, but you'd prefer to carry on making yourself look foolish.
Yup, I model most of my more complicated designs in it first.
Things curving on two axes are doable (i.e. drawing a ball) - but they are certainly harder. There are different tricks depending on what kind of result you are after.
Rhino CAD or solidworks are the good ones.
the tricks of using a 3D package are many..they are not as good as 2D in terms of ease of use.
In general using Rhino is like using very early Corel Draw. You have to think how to construct the shape and it often blows up.
The generic tools for curves in many dimensions are lofting and sweeping.
Once you understand how those work, you can usually get a pretty decent shape done.
I am not sure what Sketchup has to offer tho.
Are you still running the oldest version of XP you can get like TNP does?
You do understnd that if that one machine develops a fault you loose everything? Sometimes it relly is better not to put all your eggs in the same basket.
It was only suggested as a work-a-round method of retaining some old software. The decent m/c route would work if I were more adept or willing to employ an expert.
Bingo.
I'm afraid all his eggs are scrambled mate (and that's the only way everyone else should have them).
What he doesn't have the ability to consider are people who (for example) may be migrating an old PC over to a new (as I was suggesting for Tim Lamb) and / or may even keep both PC's running simultaneously (but with only one on at a time in most cases) and who may have no interest in an 'VM's' in any case.
I use my KVM switch to go between my Mac Mini with OSX and XP and a PC I built with the idea of running Linux as my everyday desktop (but after a long struggle realised that was a step too far for Linux, my Linux skills and *my needs*) so dual boot Ubuntu with W10 that (also, along with XP) does do all I need.
I *wouldn't want* all 4 system running on one PC under VM's even if you can run OSX on a non OSX host as that's not the point.
My mate in his garage runs a KVM switch between his old (XP) and new (W7) PC's and often has either on and *sometimes* both and his printer is networked so available to both systems at all times.
Another mate has a KVM switch to go between his 'everyday' PC and a quad-core beast he uses for editing and rendering videos.
Another mate has a 4 way KVM switch as he has 4 PC's running different OS's or versions of OS and likes playing with the PC hardware. So again, part of his usage / needs is to be able to access any one of 4 machines including at boot time to be able to tell it to boot from a DVD 'this time' but not always and to be able to destroy any OS at any time with no risk to anything else.
And of course my mate in the PC shop has 4 different machines (2 servers, a W7 desktop and Mint for emails) that he regularly switches between during the day. He has run a second machine on a first using a VM and 'soft' switching of KVM between machines but both have caused issuse so been abandoned for a far simpler and more robust KVMA solution.
There *are* millions of such examples where 'ordinary users' and technically competent people who also *choose* to use KVM switches over any other solution because *they* simply prefer it. People who have the ability to realise and accept that other people have the freedom to choose what solution is best for them without having to suffer name calling and abuse from anyone.

Ok.
Ok thanks, at least I know that it's possible. ;-)
It was a part Rick posted about a while back 'Identify this electrical fitting', that I offered to print for him as I thought that would be a classic use for a 3D printer.
A picture of the item:
I can now (thanks to your help) use Sketchup sufficiently to easily reproduce the base part and I could even duplicate the outlet 'tunnel' but I wouldn't be able to merge to two shapes together, as per the original.
I said at the time if Rick was able to measure the part as accurately as he could and someone was able to draw it and produce an .stl file (because I couldn't do the double curve bit), I'd happily print it and stick it in the post to him (but I didn't spot any follow up to see if he got it resolved).
Cheers, T i m
KVM switch. Simple, reliable, inexpensive and could be installed and used by anyone. ;-)
Quite, and most people wouldn't have to when using a KVM switch to between two (or more) machines.
Like my mate in the garage. He has his 'old PC' with all his old Sage accounting software and his 'current PC' with his latest version of Sage and Autodata etc. 'Most days' he just fires up his new PC but if he needs to access something on the old PC he hits the power button and presses the Scroll Lock key a couple of times, he's now looking at, controlling and hearing the old PC. If one machine fails he still has the other for general duties, like Internet / mail access and printing invoices etc.
Apart from the benefits of redundancy by having the two machines, he has no interest in running any VM's or transferring anything from one machine to the other as he's not a computer geek. ;-)

Woss this? Can't you spell "lose" either?
ah, ok that looks easy enough.
The way I would do that is to view that as something a bit like a half cylinder with a quarter of a sphere planted on the end.
So for the cylinder draw a cuboid of appropriate size, then use the arc tool to mark the outside top profile on the end. Now use the offset tool to create a second arc concentric with the first, marking the inside face of the half cylinder. Finally use the push/pull tool to slide away the bits you don't want.
To do the spherical component, start by drawing a horizontal circle equal to the required diameter. (to make this easy, do it on the origin of the axis in the drawing space). Now create a second circle of the same size that is perpendicular to the first and intersects with it across the diameter (so looking end on you have a cross section). Now delete the lower half of the vertical circle. and the left hand half of the horizontal one (you can draw a line with the pen tool along the axis to cut it in half). Delete half of the remaining vertical circle, so you now have a quadrant. Use the offset tool to get your wall thickness again. Delete the bits you don't need until you have a quarter arc of required thickness sticking up from your horizontal half circle. Finally use the "follow me" tool to wrap that quadrant round the path marked by the outside edge of the horizontal circle.
I might see if I can do an illustration of that and stick it on the wiki...
This is a pretty good demo of the technique:
Obviously knot. I have just noticed i have the wrong spelling dictinary on this machine but it wouldn't have helped.
I use a KVM with two computers running different operating systems.
That's the trouble with having these Windows machines locked down by the sysadmin. The user couldn't set the date/time, or the date/time format, or the default dictionary, etc. Luckily I got mine set up before the sysadmin took over.
The point is (with all this spelling pedantry, however lighthearted), is it rarely makes any difference to the posters ability or content and therefore just more noise?
Just in the same way as some people just can't seem to comprehend the context and intent of someone's writing (however well scribed), others can't always spell correctly or maybe use the wrong grammar or punctuation.
However, this is a d-i-y group, not a literacy course so if you don't like how something is spelled (especially one of the more common mistakes, like lose and loose), maybe you could just fix them in your own head? ;-)
If every grammatical error, typo and spelling mistake seen here was corrected there would be even less (fewer?) real d-i-y posts percentage wise than there are now!
Whilst I'm all for 'learning', some things are obviously ingrained and so unlikely to change anyone, even when pointed out. ;-( [1]

[1] When I were a lad I was always out 'ragging the streets' (as some used to call it) either on foot, bicycle, moped, motorbike then car and quickly learned my way around. Daughter on the other hand didn't do all that, so when she got old enough to motorbike then drive (and she did it in that order) she was pretty well lost when not in our road or the few roads she's traveled regularly. So, when I used to jibe her for not knowing her way around, she would ask me how to spell something I would generally get wrong as a way of proving the point of 'we are all different and therefore good at different things'. ;-)
To you maybe ... ;-)
Ok ...
Oh, ok. I think I would have drawn the inner and outer semicircles on the end then 'pushed' the shape down the length of the model.
I've not used the offset tool I don't think? , nope, not used that tool yet.
Ok, I'll give that a go.
(So disconnected from the model etc?)
Ok, I can imagine what you are doing ..
OK, again, it sounds followable (I'll print this off and go though it carefully later).
Ok, I can select the FollowMe tool from the Tools menu but it doesn't appear in the toolbar. I probably have to add it in somewhere. Something else I've just noticed, the latest version seems to have some live animations showing you how to use each tool. That might have helped earlier on! ;-)
That might be handy as I'm sure these 'extended' techniques might otherwise be ignored by all but the more dedicated / patient / creative types (none of which are traditionally me when it comes to this sort of thing ... but I'm getting there (on a 'needs must' basis)).
Nice bit of what sounds like Skrillex at the beginning there. ;-)
they make it all look so easy don't they but I guess it's just like anything, all down to either being shown or trying stuff yourself and practice.
Question, at 47s he says 'I'm gonna type in 3 for my radius' .. where do you type that in do you know please as I've always had to drag the cursor to whatever size I've needed (sometimes zooming in or out to be able to get the accuracy)? Ah, I've just tried it and if you draw a circle and just ignore whatever size it is and then enter say 55 (Enter) the pre-dragged value changes to whatever you typed in. I always thought it weird that you couldn't overtype the size in the box?
Thanks again and I'll let you know how I get on. ;-)

You and a million others charles ... it's always been the 'preferred solution' for ordinary folk wanting to run two machines and save deskspace.
About the only times I've had 'problems' running a KVM switch (and probably why 'some people' don't like them) was on Linux.
One was here with a USB mouse that was fine if you booted into Linux and used it, but if you switched across to the other machine and back, then Linux lost control of the mouse and it became mentally fast. Of course 'some' blamed it on the mouse, the KVM switch (or 'me' of course, for 'making it up' ) but XP, W7 and OSX could all cope with it just fine so it was obvious where the weakness was. Some kind soul actually took remote control of my Linux box and created some code that would reset the mouse speed, every time it re-appeared (just as it would if you unplugged it and plugged it back in again of course) and that worked fine, but I've since changed the mouse to something Linux can cope with as it's easier that adding the code each time I try a different version / distro. ;-(
The second *is* (currently) Linux Mint in my mates PC shop where again, switching between 4 boxes with the KVM switch can upset the graphics. If it does get confused (and the screen res can't be set right, the 3 Windows PCs on the same switch never bat an eyelid ... ), you have to go into the Screens app and click 'Detect monitor' or some such and you can get the resolution you want back again.
VMs and running emulators are good for the sorts of things they are good at. For being able to hardware-switch between machines , quickly and easily will always be the best solution for those who want the most flexibility and low level control. K.I.S.S. ;-)
