Re: [GTALUG] Securely wiping SSDs

[William Park via talk]

In addition to 'hdparm', I have 'shred' and 'blkdiscard' on my computer. 
 Other distros may vary.

I have, for many years, used "Darik's Boot and Nuke" on a USB stick to

I'm now at the point that I have to wipe and dispose of SSDs, and I'm
feeling a bit shaky on the methodology.  Here's what I did:

 # hdparm -I /dev/sdX

Looked for enabled/locked/frozen in the output ... I won't go into
making sure those are toggled correctly, but that appears to be
needed.  This also lists what appears to be info about doing a wipe on
the drive:

 6min for SECURITY ERASE UNIT, 60min for ENHANCED SECURITY ERASE UNIT

Then, set a password (why? but seems to be needed):

 # hdparm --user-master u --security-set-pass foobar /dev/sdX

Last, run the wipe:

 # hdparm --user-master u --security-erase-enhanced foobar /dev/sdX

Doing something like `dd if=/dev/sdX bs=5M count=5 | strings` (or
sending it to `less`) definitely shows that it's changed from
something organized to something full of identical characters.  But
I've never seen this wipe process take more than 60 seconds, which
makes me wonder about the `hdparm` declaration about the time required
for a secure wipe.

So I guess the big question is: should I trust this process?  Do we
really think it's securely wiped?  Or should I be taking a hammer to
the chips on the SSD because that's the only way to ensure it's fully
wiped?

'rename' from Ubuntu/Debian distro goes (from memory)
rename 'perlexpr' files...
where perlexpr is something like 's/x/y/'.

'rename' from util-linux package goes like
   rename 'pat' 'rep' files...

Exactly what's desired.



Ubuntu/Debian distros will include 'rename' where you can use regex.
How does `rename` (a Perl program, I believe?) handle globbing and 
pathname expansion?



i.e. in a folder with 3 files: one.sh, two.sh, file.tar, typing:

rename *.sh *

means rename gets passed these parameters:

one.sh two.sh one.sh two.sh file.tar


I'd be curious how they handle that (I expect requiring params to be 
quoted).



Thanks

Re: [GTALUG] Local-only mail server

[William Park via talk]

I don't think you can tell Thunderbird to read local mail spool.
- "Account Actions" gives you 4 choices (mail, chat, feed, newsgroup).
- "Mail Account" gives you 2 choices (imap, pop).  I

How about cheating a bit?  Symlink one of "Local Folders" to 
/var/spool/mail/users.  Not sure how Thunderbird will handle .msf file 
which will be out of sync.

I figure this is probably a solved problem, but it's one I've never

I find I have a lot of mail generated by cron and the like on several
local machines, and I'd like to A) centralize that mail on a local
server, and B) be able to view that with Thunderbird.  Platform is
Debian.  It's not my intention to handle my Gmail or anything like
that: this is meant exclusively for handling mail from local
computers.  Which would also mean the ability to send mail isn't
important.

Currently if I want to look at local administrative mail, I have to
use the nasty `mail` command from the "bsd-mailx" package.  (Yes, I
could install mutt - I don't like it much better.  I'm well aware it's
much more powerful.)  But do I remember to look at these emails?  No.
If instead each host forwarded these mails to a single host, and I
pointed Thunderbird at that ...  I'd have some hope of managing this
problem better.

"exim4" is usually (not always) installed on Debian systems.  It
claims to be an MTA: my knowledge of mail is so bad I don't even know
if that means it just "pulls" or is also capable of forwarding local
mail to another machine?  And what would be the recommended server
software?

Another possible solution would be to send the mail directly to a
folder on the host that has Thunderbird without using a server?  With
the snag that the host in question isn't always on, and I wouldn't
want it to run mail server software.  Is that possible?

Yes, I know this is probably bigger than I think.  I'd still like to
start poking around and finding out about it.  Suggestions welcomed,
thanks.

Re: [GTALUG] (very off topic) torque spec of impact wrench

[William Park via talk]

Solved!  I bought $56 "Litheli" cordless impact wrench from Walmart. 
It's slightly lower torque than what's sold at Amazon, but can't 
complaint about the price, though.  I think, it was caused by surface 
rust between the bolt and wheel rim, and not on the threads.  So, impact 
helped to loosen it.

Re: [GTALUG] (very off topic) torque spec of impact wrench

[William Park via talk]

This is what happened after getting 4 new brakes and 2 new calipers at 
the dealership.  They over-tightened it!


- I tried 12in pipe (it's all I have).  It slips, and I don't want 
to step on that.  Maybe longer pipe will work.


- I've been told (by YouTube, Google) that you shouldn't apply any 
oil or anti-seize grease.


- VW uses 17mm bolt, instead of lug nut.  So, cutting them off is 
not an option. :-)



1. I'll try to find 2-4ft pipe at reasonable price.

2. If not, Canadian Tire has sale on "air wrench"
- 
https://www.canadiantire.ca/en/pdp/maximum-impact-wrench-with-built-in-regulator-3-8-in-0581968p.0581968.html

Web says "3/8", manual says "1/2", and I'll see what the box says.

Thanks guys.  I wish I paid more attention to "shop class" in high 
school.  "If I knew then, what I know now...".

In case I messed up that term, think soundblaster pro live.  I have a

Unless your items firmly have DOS drivers that is less of a concern.

Re: [GTALUG] looking for a general purpose boot media to keep in case of distasters

[William Park via talk]

1. Use the distro iso to boot gui/text terminal.  Most distros are 
"live", so you don't need a separate "rescue" disk.


2. Use Ventoy.  It creates 2 partitions on USB stick, one Linux stuffs, 
and the other Windows partitions where you drop iso files.  When you 
boot, you can select which iso you want to boot from.  It works on some 
computers, but not all.

My research tells me that by booting from USB media, it's possible to 
install on a connected drive of any sort. Normally you use the internal 
hd but can use another external drive. Then you have a persistent 
bootable USB where you can install stuff + store files. *However* it is 
unique to that device so it'd be required to set up a USB key for each 
one. Not ideal although possibly worthwhile for the main computer.


Any advice on this issue? Seems like I wouldn't have been the first

Re: [GTALUG] Favorite desktop manager?

[William Park via talk]

I'm on Slackware which comes with KDE and XFCE.  I use KDE, because I'm 
used to it.  I was going to move to Kubuntu, but too lazy...

I just installed Debian 12 on a new laptop and took Gnome as

I really insist on something more Xerox PARC style.

I had been using Xfce, and liked it until (following Debian 10 software
updates) it began to act strangely.  A few months ago it started to kick
up a huge fuss about difficulties starting the Panel after a restart.
About 2 weeks back, following an upgrade, the Desktop area stopped
displaying anything -- no wallpaper, no icons from the Desktop folder --
just gray.  That prompted this move to Debian 12.

I might go back to Xfce, and assume my troubles just resulted from being 2
major releases back, but before that, what do other people use and like?

Re: [GTALUG] computer hardware testing tools.

[William Park via talk]

Getting back to original thread...  There are programs to test memory, 
cpu, and disk, because you have control of data, and can compare against 
expected data.


However, you can't easily test serial, parallel, USB, network, and other 
I/Os, because you can't easily control both side of connection.  People 
just try it, and if it works, then it works.  Eg.  Network -- Just try 
it, and if "google.com" gives you expected webpage, then it works.  Eg. 
USB -- Plug in a known usb stick or device, and if it works, then it works.

Re: [GTALUG] wireless to ethernet adapter suggestions?

[William Park via talk]

Yes, I'm using Asus RP-N12 Repeater (in client mode) right now.  I have 
bunch of devices in the basement with ethernet port only.  My network is 
wireless router upstairs.  In "client mode", it connects to my wireless 
router like normal client and bridges the connection to its single 
ethernet port.  Then, the repeater is plugged into a switch along with 
the said devices.  No problem getting DHCP IP, going out to internet, 
pinging local devices, etc.


I don't think RP-N12 is available now.  So, look for phrases, like
- client mode
- wireless network adapter
- wireless bridge, media bridge
- connects TV, gaming console, etc
in the current models.  I'm used to Asus, but I'm not sure what is the 
current state of market.

Hi wise souls,
I hope I ask this question clearly, as it may be hard to picture.
My new landlord is including Internet in my rent, all the more 
motivation to find a solution.
he has bell, fibe for home, which includes things like Internet, but is 
not very aware of unique methods of using the Internet, like Ethernet 
connections.
  for the past year I have quite easily used fibe connections with my 
main machine, so I feel sure this may be more about distance than 
anything else.
There is no physical modem in my apartment.  Instead, I have a set of 
two adapter I got from the source a few years back.
they plug into the wall, have a single Ethernet  jack, and when the 
other item is connected to the modem  via the same method, I can use the 
network, no extra software involved.
The problem we are having though is that for unexplained reasons I loose 
internet access, sometimes for minutes, sometimes for several hours at a 
time.
My first thought was that perhaps the service  upstairs thinks i am a 
threat, but again my new landlord has no idea how to check for this.
To be forthright the Internet shakiness is becoming a major factor for 
me personally, I still have no land line, doing a great deal of work 
with resources on line, like reach my office email.

Leading me to the question.
given adapter  like the one I am using now existed, think 2017 or 2018, 
I am guessing comparative ones exist that allow the Ethernet connection 
to tap into a wireless network.
By which I mean,  there will be no need for the adapter to be physically 
connected to the service modem, the adapter can draw  upon  the wireless 
resources, while still providing say a single Ethernet jack.

Anyone know of such an adapter?
amazon Canada would be wonderful as I have a gift card balance just now.
If confusing, ask questions that make it easier to follow,  my main 
computer uses Ethernet only, I have no wireless resources whatsoever.

Thanks,

Re: [GTALUG] ThinkPad T14s Gen 2 Intel (14”) -- good deal?

I decided against buying it.  It doesn't have builtin ethernet port, and 
power port is not the square plug like other (older) ThinkPads.


My company upgraded to ThinkPad P1 (64GB ram, 1TB ssd), and it's crap. 
First laptop didn't recognize AC power plug, forcing me to charge via 
USB-C.  Second (current) laptop crashes everyday, especially during Zoom 
but not always.


I'm looking to upgrade my desktop.  Hopefully with a laptop, but another 
desktop is okay too.  I was going to buy the same laptop as work laptop, 
and I'm glad I waited.

The more precise question would "is this a good deal for me?"
Unfortunately we don't really know what you need or want.

My current ideas about Lenovo:

- they have horribly high list prices

- they often put stuff on sale.  Usually 40-50+ percent off.

- (all brands) expandability of notebooks is being reduced.  Different
   models are different.  Pro Tip: apparently no LPDDR4 DRAM is in sockets.
   Many machines have no RAM sockets -- all soldered.
   Some have soldered RAM + 1 socket (a lifeline but annoying because
   two matched SODIMMs perform better).
   
- they have a changing array of coupons to give you additional discounts.

   They are not secret but they are sometimes hard to find.

- sometimes you can get significant cash-back by going through rakuten.ca
   10% yesterday and today but that is higher than normal.  I've seen it at
   14% a couple of weeks ago.
   Note: rakuten does not combine with some coupons (hard to figure out
   which)

- there is an educational / first responders discount through id.me
   I know little about it because I don't qualify.

About this particular computer:

- for that much money, I'd demand perfection.

- I'd prefer a better screen (more pixels, more nits, better colour
   perhaps, maybe touch)

- I'd prefer a later generation Intel CPU.  They really seem to be getting
   better in each recent generation.  I also prefer AMD but I think that
   Intel is now getting close and has some advantages (Thunderbolt,
   "efficiency cores").

   (AMD Ryzen CPU naming is a misleading mess.  You have to look up the
   particular chip to find out the microarchitecture generation.)

- I have not bought ThinkPads recently because the price premium has been
   too high.  I certainly liked much about my ancient ones.
   Exception: I bought ThinkPad C13 ChromeBooks but they were less than
   $200.

- 16G RAM is much better that 8G but is it enough for the long
   amortization period of such an expensive notebook? (Three years ago I
   threw 32G in my main notebook because it was so cheap; I don't know if I
   need it)  For most people, 16G is comfortable.  For you: I have no way
   of knowing; probably you don't either.

- I find interesting deals on redflagdeals.com, in the Hot Deals Forum.
   Deals come and go.

- Randomly, this is cheaper and has better features but is a ThinkBook
   rather than a ThinkPad (not the same quality).  Note: I'm not
   recommending it (I haven't looked closely at it)

<https://forums.redflagdeals.com/lenovo-canada-thinkbook-14p-14-2-2k-ryzen-7-6800h-16gb-512gb-895-after-codes-2596420/>

- if still available, this is a little more than half the cost of the
   ThinkPad and better in some ways.  You may detest the format: touch
   screen, can be folded into a tablet.

<https://forums.redflagdeals.com/lenovo-canada-yoga-6-13-c-amd-dark-teal-aluminum-top-cover-starting-714-now-690-2600460/#p37263784>

If you don't mind a barely used ThinkPad, this guy bought one at a very
good price from Lenovo, decided he didn't need it, instead of returning it
offered it to the community at cost, got stiffed, and is probably stuck
with it.  So: he might accept a bit less than his asking price:

<https://forums.redflagdeals.com/open-box-lenovo-thinkbook-14p-ryzen-5-6600h-16gb-512gb-ssd-2-2k-screen-835-2600803/>

Somewhere in the forums he mentioned why he didn't like it as much as
other choices.

Note: his price will not be subject to HST.  He might be able to give
you a copy of his original invoice which will show the HST he paid.

Note: I haven't talked to him about this so much is guess-work on my part.

[GTALUG] ThinkPad T14s Gen 2 Intel (14”) -- good deal?

[William Park via talk]

I just received email promo from Lenovo:

ThinkPad T14s Gen 2 Intel (14”) - Black
https://s.bluecore.com/Utrkeyg72dZq_0DQf820_NrJxD

Is this a good deal?

Re: [GTALUG] Ubuntu Pro - a new, non-optional walled garden from Canonical

[William Park via talk]

When I click "Get Ubuntu Pro now" button, I see $500/year at the bottom, 
which is a bit too much for Linux.  At least, Apple owns the hardware 
and software.  But, with Linux, you have to get the hardware yourself, 
and install the software yourself.

contact Canonical to find out. Whenever I see that, I expect an

I guess that I need a Matrix client.  This will eventually turn out not to

Element and Fractal seem to be good choices for client.
Both are distributed as flatpaks (grrr.).

I try to load each of them from the Gnome "Software" GUI, and when that

try the command line.  Which also fails with an obscure message

I end up using a web version of Element.

I first try Fedora's: matrix is federated so surely I can see
mozilla's channels from Fedora's matrix.  I cannot figure out how.

Then I see that Mozilla runs its own web-based Element so you can use
that as a client.

Turn on FireFox profiling and study the results.


So far the results are opaque.

Re: [GTALUG] rejuvinating an old machine: inexpensive SSD

[William Park via talk]

That's cheap.  But, if the OLD machine worth $35? :-)

On 2023-01-02 14:17, D. Hugh Redelmeier via talk wrote:

Old advice: If you are still using an old machine, one that uses an HDD to
hold the OS, consider replacing the HDD with an SSD.

Why do I bring it up now?  Because SSDs are getting even cheaper.  Some
think that they will get cheaper still in the next little while.  But this
drive is cheap enough that it is hardly worth thinking about:


Currently $33.99.  You may have to add something worth $1.01 to your order
to get free shipping.  Here's some candy for $1.39:


Good:
- cheap
- 512GB is a comfortable size
- TLC rather than QLC
- 2.5" SATA so it easily replaces an HDD
- if you don't have a bay for it, it is light enough that duct-taping it
   into your case is often good enough.  So you might be able to add it to
   your system rather than replacing an HDD.

Bad:
- no DRAM
- 2.5" SATA; NVMe is better (but if you have a a suitable M.2 socket you
   are probably already using it for an SSD
- you might want a larger capacity

To follow-up: that would be a simple two drives in a mirror setup.  So,

Re: [GTALUG] At the GTALUG AGM: How we handle Internet services

[William Park via talk]

Just give 2 choices: (1) Move to Google.  (2) You volunteer to run the 
legacy systems.  I can bet no one will volunteer.



On 2022-11-27 21:01, Evan Leibovitch via talk wrote:

[Apologies if you received this message more than once]

Hello everyone,

By now you may have read or heard elsewhere about the announcement of 
the Annual General Meeting (AGM) for the Greater Toronto Linux User 
Group (GTALUG), to be held virtually 
 on Tuesday December 13.


Along with other AGM business, we will be discussing how GTALUG goes 
forward with our online services.


TL;DR: A number of the people who used to set up and run our online 
services (mainly the website and mailing lists) have left the GTALUG 
Board, and those who remain have neither the time to fix nor familiarity 
with the tools currently running these services.


As Google has provided to GTALUG its nonprofit services which include 
full access to commercial Google Workplace (formerly G Suite), the Board 
has been investigating migrating some of our online services there.


While to some such a move would be controversial, the status quo is 
unsustainable. So either we need new people to step forward to operate 
what exists, or we need to move to a service -- provided free of charge 
-- that can dramatically simplify operations.


The Board wants to have an open discussion on the issue before deciding, 
and the issue will be raised at the AGM. We look forward to hearing your 
views. While responses to this email will certainly be read, the full 
discussion will take place at the AGM.

Modern power supplies are pretty tricky.

Lenovo support should be able to handle this.  Of course there are a
few
problems if it involves returning the device:

- how can you eliminate confidential files from the system before
   returning it?  Theoretically very difficult with an SSD
(wear-levelling

- all your work configuring the system needs to be redone when you
get it
   back.

- you are missing the machine for a few weeks.

I think Lenovo offers a service that allows you to retain the disk when
you send the device in for repair.  It may cost.

Re: [GTALUG] war story: Thunderbird needs to be told to compress its folders

I use Thunderbird.

TL;DR:
If you use Thunderbird, once in a while, do this:
File: Compact Folders

This may be the only way to get space back

Now for the war story.

One of us uses Thunderbird to read mail.
It stopped working yesterday, with no useful diagnostic.
In particular, it would no longer pick up mail from our POP3 server.
There was no signal to the user.

I looked in the Error Console (meant for developers, not users) and
saw two messages, the first being:
   tb.account.size_on_disk - Truncating float/double number.

What does this mean?

First guess: Javascript stores numbers in 64-bit IEEE 754 floating
point representation.  A large integer may not be precisely
represented.  But there are 52 bits for the fraction AKA mantissa and
2^52 is very very large.  My mail files were at most a small number of
gigabytes - perhaps 2^32.  So this cannot be the explanation.

Googling didn't help: the message showed up in posted logs but wasn't
relevant to failure to fetch mail.  Still, some did suggest that a
Compact Folders command was in order.

About three gigabytes of space freed and the first message
disappeared.



We still could not pick up mail.

 I'd recommend Windows laptops.  You can wipe it out, do dual boot, use

dimensions I have in mind are something like: 3840 x 1080. When I load
the graphic for the desktop in the settings, I just get the graphic on
one screen. If I select the jpg from the file manager (Dolphin) to set

If anyone can be of help I would appreciate it.

I bought one from them last year, but it only has 1 Gb Ethernet ports. 
It works well with pfSense.  Here's a recent speedtest on my Rogers

Re: [GTALUG] From Slackware to which distro?

[William Park via talk]

I decided on Kubuntu 22.04 KDE.

What I looked at
- KDE, XFCE, and GNOME desktops on Ubuntu, Fedora, OpenSUSE, Debian 
distros and spins.
- jq, xmlstarlet, netpipes, mplayer, virtualbox, firefox, 
thunderbird, ibus-setup, vnc.  They are representative of small, big, 
common, not so common apps.
- GUI software manager.  I just can't remember apt, dnf, zypper, 
snap, flatpak options.

I used to build and update .rpm packages back when I was using a distro 
that used RPM for package management. If you aren't creating your own 
package from scratch the simplest approach is to download and use the 
.src.rpm file for the package you want to update. You can modify the 
.spec file with the name of the newer source code file.


You will also want a .rpmmacros file which sets the packager name, the 
build directory, and the temporary directory that will be used by rpmbuild.

[GTALUG] Making RPM from directory tree?

[William Park via talk]

To RPM guys,

I have a directory tree, created from "make install DESTDIR=...".  Now, 
I want to make RPM package from the tree.  Online docs are too verbose 
and confusing.

1. Is there GUI app with appropriate fill in boxes?
2. Is there command line utility?  In Slackware, it's just "makepkg".

Background:

I use "netpipes-4.2" a lot.  Debian and Slackware have it, but Redhat 
variants don't.  I can use netcat and pipe (and I do), but there are so 
many variations (ie. nc, netcat, ncat), each with different behaviour 
and options.  I like to use what I'm familiar with.


So, I downloaded the source, compiled it, and installed to a directory. 
Now what?

Re: [GTALUG] Default VNC in XFCE?

[William Park via talk]

I finally figure it out.  As I said, in KDE, "krfb" and "krdc" are the 
default vnc server/client.  So, I've been trying to figure out their 
equivalents in XFCE desktop.  Xubuntu had none.  OpenSUSE seems to have 
TigerVNC as default.


So, I tried TigerVNC.  The client side is "vncviewer".  But, the server 
side was confusing.  All the online docs talk about running virtual 
desktop (like :1, :2, etc).  But, I just want to shares my current local 
desktop (:0), like "krfb".  The answer is "x0vncserver".

If you have fairly new hardware, then general wisdom is to go with 
bleeding edge distro, like OpenSUSE Tumbleweed and Fedora.  Try them on

That's the main one.  My motherboard got fried.  So, I bought a new 
motherboard.  I booted from ISO, and checked that the disk can be 
accessed and the filesystem is not damaged.  All was OK.  So, I tried to 
boot from it, but couldn't.  Eventually, I booted from ISO, bind mount 
all the mount points, chroot, and reinstall boot loader.


Second bad experience is moving from smaller disk to larger disk.  With 
MBR, you just "dd", adjust the partition, and then the filesystem.  With 
GPT, you can't do that, because GPT has secondary partition table at the 
end of disk.  Nowdays, you use Clonezilla or GParted for that.  OK, 
minor point.

I don't really understand everything about BTRFS.  I understand it can
partition the storage it manages, a bit like LVM.


I'm told it's more like ZFS (I haven't used ZFS).  I use btrfs for 
backup/restore, because
- It allows me to combine many non-identical disks into single 
"drive".  I'm still using Samsung rotating hard disks which I paid good 
money for.
- It can take snapshots, daily, weekly, and monthly.  Snapshots are 
generally cheap.

Why do you want MBR?  I switched to UEFI many years ago.  Generally it is
a win.


I have bad experience with UEFI.  You can't just move the disk to a new 
motherboard, and boot.




Reading more carefully, I think that you mean that you have GPT
partitioning on all your disks, with only one partition on all disks
except for the one you boot from.  On your boot disk, you have a /boot
partition and a single / partition for the rest of the disk.  /boot appears
to be MBR to GRUB but GPT to the running system (a very useful hack)
No, my current boot drive is 500GB MBR, with one partition and no swap. 
 Just /dev/sda1.  I used to have /, /boot, /home, and swap partitions. 
 I now put everything into /.  So, to upgrade, I usually

- move /home and /etc to /old
- remove all others
- install new distro
- restore from /old/etc and /old/home

For UEFI, I would need 2 partitions (/ and /boot/efi) at minimum.  Some 
distro adds /boot and /home.  So, 4 partitions.  I don't know

- if UEFI came about to support these multi partitions, or
- if distro are simply taking advantage of GPT.

When disk fails, it rarely fails by partitions.  It fails as whole disk. 
 So, partitioning isn't as useful as it sounds.


All other disks are raw disks in raid1 multi-disk btrfs.  So, it uses 
/dev/sdc, /dev/sdd, ... as whole, not /dev/sdc1, /dev/sdd1, ...




UEFI Losses:

- more magic (i.e. a little more complex).  But fewer hacks.

- You can only run x86-64 OSes on an X86-64 UEFI. (With MBR you can boot
   16-bit, 32-bit, and 64-bit OSes.)

- very old machines don't have UEFI.  (Surely your computer has UEFI
   firmware.)

- you have to have an ESP (EFI System Partition) and it has to be VFAT so
   it pretty much has to be a separate partition from the partition(s)
   holding your data and system.  But it need not be very large -- 500M is
   plenty.  This is much less of a burden than your /boot.


UEFI Wins:

- booting becomes less fragile

- supporting more than 4 partitions is less hairy

- allowing multiple OSes on one drive is a lot easier

- UEFI is a well-tested path, both for the hardware and the OS.

- considerable hardware no longer has an MBR option

- firmware updates can often be managed by Linux.

- many manufacturers provide diagnostics as .efi programs.

- Secure Boot.  Why not?


Partitioning:

I do a bit more partitioning than you do.

I have a separate /home.  That means that I can replace the OS and
leave the users' files.

The only exception is on machines with tiny disks: partitioning a 32G eMMC
on a netbook is almost guaranteed to strand precious space in the wrong
partition.

Each OS that I intend to boot needs its own partition(s).  I often have
dual boot Fedora / Windows, even though I rarely use Windows.  Sometimes I
have two versions of Fedora, each on its own / partition.  Sometimes I
have Fedora and Ubuntu.

I often have a swap partition.

Modern disks are so large that I often leave space unassigned to a
partition.  That lets me decide what to do with it when I need it.  It
should also contribute to the longevity of SSDs (effectively this is
massive over-provisioning).

 1. My motherboard takes a single M.2 SSD for my one and only drive. I

existing setup to the new drive (in a temporary USB enclosure) then
installing and shrinking the Windows partition in anticipation of
the Linux dual-boot install. Can anyone recommend a good tool for
doing the disk clone? Or am I better off to just fresh-install
Windows on the new drive, and restore my data from the old one?


GParted, Clonezilla, or even Windows might have something.  I mean, 
upgrading to bigger disk is common thing, no?




 2. I want to have one partition for data that is visible regardless if
I boot Linux or Windows. Previously the most reliable filesystem
readable by bothwas FAT32. Should I still do that? Is Linux support
for NTFS good enough now? Even better, can Windows be taught to read
ext4?


I can read/write NTFS USB sticks.  So, should be okay.

- OpenSUSE -- Difficult to pin down.  It uses RPM but in their own way. 
It has rolling release (Tumbleweed) and versioned release (Leap).


- Arch -- no.  I don't need/want to learn what they are trying to teach. 
 I run Slackware, so I already know all that.


Thanks for any feedback.

I'm using Thunderbird 68.12esr.  I just downloaded Thunderbird-91.8.1 
(latest), and found that it doesn't import settings from the old one. 
WTF!  It'll take a week to regenerate all the filter rules and account 
settings.  OS needs upgrading too. :-(

Thanks Seneca.

[GTALUG] Gmail + Thunderbird

[William Park via talk]

For a while, I couldn't send out through SMTP@Gmail using Thunderbird. 
POP@Gmail was okay though.  It turns out Gmail switched to "app 
password" like Yahoo did.  Once you generate "app password" (2-factor 
needs to be ON), you have to use it for both POP and SMTP.  Web login is 
the same as before.

Re: [GTALUG] two or three tricks for installing Linux as a second OS on a Windows box

[William Park via talk]

I used to dual-boot, but now I use separate Linux computer.  If I need

can't be bothered.  Less headache, and I'm not getting younger.

On 3/4/22 11:27 AM, D. Hugh Redelmeier via talk wrote:

Most computers come with Microsoft Windows.  If you insist on buying a
computer without Windows, you have less choice and may have to pay more.
Besides, once in a blue moon Windows is useful.

To install Linux, you can either blow away Windows (easy!) or your can
install Linux beside Windows.

If you want to install Linux beside Windows, you usually have to get
Windows to relinquish some disk space.  (Alternatively you might be able
to add another disk.)

Windows has a way of reducing the size of a volume but it is unwilling to
relocate a structure that is in the middle of the volume.  So it is only
willing to give up slightly less than half of the volume.

I use gparted (ntfresize is underneath) to shrink a Windows NTFS volume,
because I always want to shrink in to less than 50% of its original size.
I do this from a live Linux flash drive.

Here are the tricks that are not so obvious:

- if Windows is using bitlocker, you need to turn that off in Windows.
   Otherwise gparted cannot do anything with the partition.

   Our newest computer came with bitlocker enabled (with no password).
   That's probably a good idea but not for us.

   After bitlocker is turned off, gparted can operate.

   Perhaps you can turn it on again after resizing.  I don't know.

   (On Windows: Settings: Privacy & Security: Device Encryption)

- By default, Windows assumes that it can leave the filesystem in an
   inconsistent state when it shuts down.  It assumes that you'll boot
   Windows again when you power the system up.  Apparently this speeds
   things up a little bit.

   This is very unhealthy if you are going to boot Linux next,
   especially if you are going to run gparted to muck with the NTFS
   filesystem.

   You can fix this by going to Windows' Control Panel (which is something
   different from Settings), Power Settings, and untick "turn on fast
   startup (recommended)".  It is slightly tricky because you have to click
   some option to allow you to change the fast startup option.  Sheesh.

- (old advice; may be obsolete; I don't wish to find out the hard way that
   it is still needed.)
   After you have resized the NTFS partition, reboot to Windows.  Don't do
   anything else with the disk in Linux first.
   Why: it used to be the case that gparted got something slightly wrong in
   the NTFS partition, something that a Windows boot fixed silently.
   After booting Windows, you can reboot to a Linux install medium safely.

Re: [GTALUG] decent cheap ChromeOS tablet -- can run debian in a container

https://forums.redflagdeals.com/lenovo-canada-chromebook-10e-tablet-129-less-rakuten-2501804/

This is $129 tablet seems to be aimed at kids in schools.  It's not
particularly powerful, but it has a nice screen (1920x1200, 400nit),
battery, and a solid build.

This version of ChromeOS invites you to create a container with debian in
it.  The debian is from the debian repos: not customized.

I've done so.  I can run xterm, but it is awkward without a keyboard and
mouse.  I've loaded gnome desktop but I'm not sure how to start it.  I
wanted to use gnome's on-screen keyboard.

Seems like a fun toy for this price.  The weakest point is that it has
only 32G of eMMC (disk) and no slot for an SD card.

It has only one USB port and that is used for power.  I was able to use a
USB-C hub with "power delivery" to add more peripherals.

The sale might end at any time.  Perhaps the end of the day or the end of
the weekend.

Re: [GTALUG] help with Rogers SMTP

Your screenshot looks OK.  Rogers is using Yahoo.  Yahoo changed the way 
you authenticate to POP3/SMTP servers.  They won't accept your web login 
password anymore.  You have to log into their website, generate "app" 
password, and copy that into Thunderbird.


That's what I remember.  But, looking around Thunderbird now, I can't 
find where you'd enter that password.  I guess, when you create the 
server account.

[GTALUG] ssh in Windows Cmd and PowerShell

[William Park via talk]

FYI...

While doing "back to office" setups, I noticed that you can do ssh in 
Windows Cmd and PowerShell.


Traditional way was to install WSL (Windows Subsystem for Linux) and do 
ssh from Ubuntu.  One hassle was that Ubuntu can't go into Windows 
network drives.  Now, you can go into network drive in "cmd" and 
"powershell", and do ssh from there directly.


This means, I no longer need my Chromebook.  Its original and 
replacement batteries both died, so I removed it from Chromebook.  I use 
it for SSH terminal mainly.

There are other language in use: Python for ML, Java for big data and

Re: [GTALUG] Swapping ThinkPad drive

For /, /home, ... it's simple copy.  Since you're using external USB, 
don't use "dd".  "cp -a" should be good enough.  Or, "tar -cf -".

Never used "cpio".

For /boot, it's different can of worm.  You can copy over the content, 
but you have to update /boot/efi/EFI/DistroX/, so that your motherboard 
"BIOS" knows about it.  I'd recommend, install your distro on the new 
SSD using UEFI.  Then, update files for your old kernel.  That way, the 
structure is created for you.


Personally, I don't like UEFI.  If you change motherboard, you can't
