I do not have a complete solution for you, but here are a few<br>
thoughts.<br>
<br>
Firstly, you should understand that you are going into a potentially<br>
hostile environment by advocating some flavour of Linux to people who<br>
use Mac and Windows. This has a few implications:<br>
<br>
- There are effectively no replacements for the software you are<br>
listing. You might be able to make some software work with WINE<br>
(although see below) and there may be other software with similar<br>
functionality, but every quirk will be grumbled about unless your<br>
userbase sees Linux as a grand adventure. Expect a lot of threats<br>
that "if this doesn't work then I am going back to Windows"<br>
<br>
- By advocating for Linux you are effectively volunteering to become<br>
the systems administrator. Over time you might be able to get other<br>
people sufficiently interested in helping you out, but in addition<br>
to helping research and implement this solution, you are also going<br>
to have to take care of it.<br>
<br>
Having said this I endorse your efforts to get free software into this<br>
makerspace. I think that there is a lot of software available for<br>
maker-ing that is available on Linux-type platforms, but little of it<br>
will be a direct replacement for what is on Windows.<br>
<br>
You will have to spend a lot of time figuring out whether you can<br>
find software that will work with the 3D printers, CNC routers and<br>
other toys. If there are not then you will need at least a few Windows<br>
machines on site. (It sounds as if you are on this already.)<br>
<br>
Your comment about Deepfreeze inspires a rant. We use a competitor<br>
called Drive Vaccine in our Windows labs, and we (okay, I) am very<br>
unhappy with it. The big issue with these products is that you need to<br>
allow changes to the Windows machines to do updates, but not to do<br>
anything else. I would hope that Deepfreeze is better than our product<br>
in this respect, but I have been pretty unhappy with our experience.<br>
<br>
In contrast, using guest accounts in Ubuntu has worked really well.<br>
The machines stay clean, and if you do the initial setup (which is not<br>
trivial -- there are often custom modifications that have to go into<br>
/etc/skel, and getting printers to show up automatically can be a<br>
pain) and then allow unattended-upgrades then the systems do not<br>
require a lot of additional maintenance (in our experience). So I<br>
think an Ubuntu environment might give you a clear win there. You can<br>
also have an administration account that has sudo access, but which<br>
regular members of the makerspace can't log into.<br>
<br>
WINE can work for some programs, but in my experience it often is a<br>
big pain. Trying to get Windows programs working in Linux overall can<br>
be a big pain. One big issue is that we have not figured out how to<br>
get WINE working system-wide (as opposed to installs on individual<br>
user accounts) which makes /etc/skel really big, and in turn makes<br>
logins painfully slow.<br>
<br>
Usually if I want to have access to Windows machines from Linux<br>
clients, I just set up an actual Windows machine (physical or virtual)<br>
and then use remmina to RDP into those Windows machines. This is not a<br>
perfect solution, but it can be "good enough" depending on the tasks<br>
you need. Screen sharing with VNC might be another option.<br>
<br>
If you are administrating computers where each user gets a unique name<br>
and password (which I do not think is the case for you now) then<br>
managing those accounts centrally can be a pain. You might consider a<br>
Samba 4 solution, or even a distro like Zentyal which makes setting up<br>
an Active Directory solution easier. The nice thing about this is that<br>
then your Windows clients can join the "domain" and have similar<br>
access and permissions as your Linux ones.<br>
<br>
I second the recommendation to raise this thread on the Kwartzlab<br>
discussion list.<br>
<br>
I don't know whether any of this blather was helpful, but I hope it<br>
was not too disheartening.<br>
<br>
