Yes, AFAIU, it also uses Xen so your concern seems valid.

I wonder what the cost of verifying is? :)  (Specifically, that the games you are interested in really don't perform as well as you'd like.)

Do you have a good method for restoring?

Yes :)

I've wanted to try Xen as well for some time, but some how things never quite worked out.

I don't really have good answers to your questions, but perhaps you might find Qubes to be of interest.

I do, but not with Qemu running under Windows.

Status update: have been using NixOS for over a year now, has been quite good, though took quite a while to get used to.

Also tried Guix -- a bit more to my liking (based on pieces of NixOS), but still has a ways to go.

Tried Manjaro again (thanks to phitsc) -- the brief experience I had with the Fluxbox 15.10 edition this time has been nice so far.

Wondering whether to try out Qubes -- this appears to be a focused effort to carry out an idea of isolating execution of programs (perhaps among other things).  Anyone else try this already?

FWIW, I try not to dual/multi-boot these days -- swapping out the storage media seems to work better (though physically more work).  May be that's not so practical for your case...

Good luck in any case.

Just tried out qemu-launcher:


Part of what it does is provide a GUI for creating / editing sets of information for launching the qemu emulator.

Was thinking that a general GUI tool to do this sort of thing for any command line program (i.e. rather than specifically just for one program) could be handy.

Perhaps one could provide (for each supported command line program) a template describing options, corresponding GUI layout, and how what's specified gets translated into command line parameters.  A motivated user might provide / share their own templates.

IIUC, some of this is done by Drag and Drop Robot -- the creating / editing sets of information part at least.

Insert usual comment about if suitable thing doesn't exist already :)

Glad to hear it!

Some folks have been noticing that over the years, various apps appear to "phone home" from time to time.

For example, Firefox seems to contact a variety of locations -- they do provide some info about this and often how to disable:


but there does not appear to be a single preference one can select to disable all such behavior (or alternatively, turn stuff off temporarily and restore later).  Also it turns out in some cases it's a plug-in (e.g. IIUC, NoScript may talk to -- please point out if this is incorrect).

I also noticed that at some point one of the tracking related settings had gotten enabled here :(  In general, I'm not too happy about settings changing behind my back...

So this leads to an idea...

A policy-checking / reporting plug-in or app -- perhaps at first for FF, but may be also for other apps.  A rough idea of it is to be able to specify a policy (e.g. no non-user initiated connections) and then get a report on whether it's followed and perhaps to warn when the policy appears to be violated.  Being able to load / save various policies might be nice too.

I realize that doing this in detail is likely to be a fair bit of work -- was just thinking something simple might be possible to gain a fair bit of benefit.  Perhaps something that just checks a certain set of settings -- not actually try to monitor app behavior.

May be such a thing exists already, but if not... :)

Didn't manage to get passed a certain point, but perhaps the following will be of some help...

I tried booting from one of the XFCE 15.09 isos and saw a screen of text with some lines offering among other things a UEFI option.  The text I saw was something like:
Manjaro Linux x86_64 UEFI DVD (default)
Manjaro Linux x86_64 UEFI DVD (nonfree)
UEFI Shell x86_64 v1
UEFI Shell x86_64 v2
EFI Default Loader
Reboot Into Firmware Interface

FWIW, to get this to show up, I needed to enable UEFI in my BIOS as I try to avoid using UEFI whenever possible.


One notebook I tried with didn't get far beyond the initial text menu, but a second notebook reached the graphical desktop.  This was the case for both the DVD media as well as a USB stick with the content of the DVD media on it.

I noticed that there's a 15.10 Fluxbox edition, so just tried that.  Was able to get to the graphical desktop on the "problematic" notebook.

On a related note, there appear to be a few prerequisites such as disabling secure boot and installing to GPT-using storage.

Don't know if it will help and it's a bit dated, but FWIW:


Is it possible to have an arrangement where it's possible to make new content available soon and gradually add in older content?

Wouldn't you have to load it into a VM anyway?  I never hears of Windows running directly on Macs.

May be I misunderstood, but isn't BootCamp one way to run a variety of Windows OS' on Macs?

140's it going? :)

Further Stagefright-related patches (plus others) included in recent update:

The most severe of these issues is a Critical security vulnerability that could enable remote code execution on an affected device through multiple methods such as email, web browsing, and MMS when processing media files.

IIUC, these are related, but not the same as originally reported.

I really like some of the ideas behind Git (such as how blobs automatically handle de-duplication of data), but I hate the tools I've used to try to interact with Git.

Which ones have you tried?

I also wasn't too happy with many of the tools I tried -- a couple that helped a fair bit though were SmartGit(Hg) and magit.  These days the command line seems sufficient for many tasks, but while still learning the ropes, I found the aforementioned tools to be handy.

Why not?

I don'r recall clearly :)

I think it had to do with a hiatus and having picked up git along the way.

I used to use Mercurial, but haven't lately.

I found the explanation of rebase in terms of cherry-picking to be useful and diagrams seemed appropriately employed in explanations (will there be a UI at some point that allows manipulation of repositories via graphical means? [1]).

In general I found the order of presentation to be sensible.  A bit odd at times where things that seemed quite basic were explained given the title of the talk (e.g. about abbreviating commit hashes), but found it worth watching.

Thanks again, phitsc.

Hadn't seen that one.  Thanks for sharing!

I tried the command for a Windows environment and observed "enabled" as well.

when I check out ipconfig /all, I see my MAC in my IPv6 address...

FWIW, for ipconfig /all, when I look at the value for "Physical Address" and compare it with "Link-local IPv6 Address", I don't see much similarity.

Thanks for the links.

IIUC, it may be relatively straight-forward to check from a terminal app in Android whether privacy extensions are in use:

ip a

The result may show information for various network interfaces -- for WiFi, a typical interface name is wlan0.  Examine the displayed MAC address and IPv6 address -- roughly, if the last 3 bytes are the same in both, I think it's a good bet that (at least for that interface) the extensions are not in use.
