Backing up to (or restoring from) the same drive will be slow.

I just find the last commit of Gnash (almost two years ago)[1], It did
say "Gnash is currently not being actively maintained".

For an alternative to Adobe Flash, Ruffle[2] is indeed worth watching, but
they seem to have been in the proof-of-concept stage for a long time.

Take a look at Ruffle, a "Flash player emulator" or so they say.
Open source. Available for Windows, Mac and Linux.  Haven't tried it
myself. No old Flash files laying around to test.

I have LSI controllers that support SATA II. This is a custom build home
server (small business server) one friend assembled for me 8y ago.
It fits my needs perfectly well. I deliberately did not buy a server as they
consume much more power. This one is running at 70-80Watt when normal and
100-120 when for example compiling something. Also noise factor is very low
compared to a real server. Of course there are limits
(memory/CPU/periferals). The machine is on UPS - I don't care about tantal
super caps. 
Each LSI card has a 6 bay cage attached and I have raided 6x2TB WD RED
spinning discs (for data) and 2x1TB WD RED spinning discs (for OS)

I somehow can not convince myself that I need to replace any of these with
SSDs.
I don't want the cheapest but also not unnecessary expensive drives, I just
find it hard to evaluate which drives are reliable.

I saw there are 1TB WD RED SSDs targeting NAS for about €120,-
 WESTERN DIGITAL WD RED SA500 NAS 1TB SATA (WDS100T1R0A)

Yes - that's what it says on the page that I linked to. And I have a

Revenue generating system? Areca with a BBU. I wouldn't spend that much 
myself on a home system, and I also don't have a home system large 
enough that there'd be a noticeable performance difference even after 
spending the money. Where something like that is helpful is if you have 
a large number of disks in a RAID6--the nvram cache keeps the write 
performance from being terrible. There are ways to do that now with 
linux software RAID, but the additional complication and less common 
configuration makes the easy hardware solution very attractive. If 
you're doing RAID1 or you don't highly value small block write 
performance then the md software solution will do just as well. 
Depending on your requirements you might also consider lvm mirrors; the 
nice thing about those especially in a home environment is that you can 
selectively mirror critical data and stripe stuff you don't care if you 
lose and relatively easily reallocate storage between different 
strategies on the fly.

I second that motion.

Unless using Windows or ESXi outside VSAN you better avoid RAID
controllers. More hassle than gain, IMHO.

Over the years I've been fond of RAID adapters from LSI Logic (now 
bought by Broadcom) [1] and Intel [2].
They have good support, nice and clean internal software used to manage 
arrays and settings.
However, depending on what your goals are, they could be an overkill for 
a desktop PC and you might be better look for HBA (Host Bus Adapter) to 
connect disks in JBOD (pass-through mode) and use software RAID 
solutions supported by OS of your choice.

Having used them for 20+ years now, I strongly recommend against
hardware RAID controllers. Hardware SAS/SATA interfaces with
mdadm or ZFS are better in every one of my use cases.

That said, the best devices of these kinds are basically the
same:

LSI 2000 and 3000 series
Broadcom BR93xx
Areca anything
Carefully picked Adaptecs

Alternatively you can tweak your /etc/security/pam_env.conf (or 
$HOME/.pam_environment).

See man pam_env(7) and man pam_env.conf(5) for details.

The optical quality on most small web cams is so bad that increasing the
resolution just means significantly more bandwidth is used to produce a
picture that's visually indistinguishable from the lower resolution
version. Most video chat applications will downsample a high res image
anyway, so generating a high res stream is just making more work. There
are cameras and applications where the increased resolution matter, but
they're the exception IME.


Very interesting, thanks. Zoom does offer standard HD and even FHD in
some cases:

You can do an awful lot, depending on how much work you want to 
put into it.

Installing uBlock Origin on your browser is a minimal step. Turn
on the logging.

You can take charge of your DNS in a number of ways.

You can record all your network activity.

How deep down the rabbit hole do you want to go?

Well, this one's for Firefox, but that's more secure than most:

https://addons.mozilla.org/en-US/firefox/addon/lightbeam-3-0/

Dropping by Adobe, and then checking out who they associate with is
interesting.

Using duckduckgo for searching, rather than Google helps a lot.
And installing NoScript works.

Open Source Flash Alternatives

[Kenneth Parker]

Since Adobe Flash is going the way of the Dodo Bird, I thought I'd check up
on Open Source Alternatives, since I have some Standalone .swf files
(games, etc).

Two came up in my searches, Lightspark (which seems to be, mainly a
Plug-in), and Ghu Gnash, which I like better, since it works as a
Standalone Program.  Unfortunately, it doesn't seem available in Bullseye
(and Search didn't find it for Buster either).  It DOES show up in Stretch,
but that's on a different machine than where my .swf files are.

What's up?

Thanks!

Very interesting, thanks. Zoom does offer standard HD and even FHD in

Interesting. On my machine, Cheese does seem to correctly list the

That's not something specific to Firefox, or to Google. Those glyphs are
what gets displayed when you don't have the correct font installed for
that Unicode code point.

Each of those blocks probably represents the name of a language, that
doesn't use Roman letters, written in that language itself.

If this only started happening recently, I'd guess either it's a
coincidence of timing (i.e., Google happens to have started displaying
those languages on its front page during the same time period), or
something different about your browser config is now telling Google that
it should display those languages there when your previous config did
not do so.

What you need to do is identify those languages, then identify the
character sets they use, then identify fonts which contain glyphs for
those character sets, then install those fonts. (And then at least
reload the page, if not outright restart the browser.)

Reco already suggested one font package (pair) to install for at least
one such language; whether that will be enough for all of the ones in
use there I don't know.


The language for a given glyph can usually be identified well enough by
searching for 'Unicode [glyph hex values]'. For example, the hex value
pair displayed in the very last glyph in that image is '0A 40'; a Google
search for 'Unicode 0a40' reveals that that glyph is from Gurmukhi.

From there, 'apt-cache search gurmukhi' finds two relevant package sets:
'fonts-guru-extra' and the 'fonts-noto-*' packages which Reco already
suggested.

If you encounter similar "missing" glyphs displayed as hex-value boxes
like that in the future, even with those font packages already present,
the same basic approach should let you get them displaying.

It's rather - firefox lacks the proper font to display Devanagari and
other languages referenced by your screenshot.

Judging from the result of "fc-list :charset=0939", you need to install
"fonts-noto-core" and "fonts-noto-ui-core", if you want to display those
glyphs.

No probs. I'll look at publishing code and cups config on github(?)

My exact model is GPrinter 1324D but it's part of a family of printers 
with the same characteristics and command set. There are other 
manufacturers who have the same command set. From my research there are 
only 2 or 3 major command sets for label printers.


There is a windows driver for the GPrinter that can be used to print to 
a CUPS printer share.

Re: Unresolved mime type.............

[didier gaumet]

Hello,

An unknown MIME type in a desktop environment does not prevent a file to be 
open by an application that can manage it but it prevents double-clicking the 
file because there is no known prefered application to open it.

The MIME page of the Debian wiki:
