Re: Email & Spam

2023-03-10 Thread Bruce Labitt

Thought that might be the case.

Is dnschecker.org at least slightly accurate? My last spam sender
address seemed to originate from or around the Kremlin Palace Complex.

Output is in my email of 4:34pm.

Honestly thinking about at least asking one of our Senators if this is
something I should be concerned about. I had a high level clearance, at
one time.

Or maybe it's ordinary spam, that just so happens to be spewing from
55.7522,37.6155 from IP address 194.87.244.234, from JSC MediaSoft
Ekspert. https://dnschecker.org/ip-location.php?ip=194.87.244.234 Does
spook me a bit, to be honest.

Essentially, no - all email headers are spoofable except the ones put

You can "generally" trust headers put on by the likes of Google
(because your server can get the IP address of the server that
connected to you) and Google IP addresses are moderately static.
However, this is not always the case.

Emails that I've sent to gmail have been bounced, maybe because gmail has
tightened their filters, maybe it's a false flag. I'm not sure and I'm not
going waste my time tracking it down right now. If someone wants to reach me,
they can just call me on the phone.

To the guy who said you should block all the IP's in the header -- that's
ABSOLUTELY WRONG! Whoever has launched this attack wants folks to do that --
they want folks to block stuff to further limit communication. Don't do that!

You can only trust the top "Received" notice in your email header. SMTP servers are
supposed to tack on their info to the top of the message and send it along to the next server, but

Radix?  That name did not show in my $ whois output.

$ whois --version
Version 5.5.13.

Well I did send all the message source info to godaddy when I filed the 
abuse complaint.  I also sent the same info to my ISP.  There's 
practically been no change so far, just a new "sender" has arrived to 
take the previous one's place.

Apparently this is an ongoing battle. Are there any better ISP's that 
are more aggressive about taking this spam issue more seriously?  Are 
there any anti spam laws in NH, or the US?  There is the CAN-SPAM act, 
according to the FTC, but these spammers put in enough info to 
technically be close to compliance.

The fact that many of these spams are

effective at stopping spam than reporting domain names.

There are likely automated ways of doing that, but I am not familiar 
with them.  I do know that mail server reputation is something that 
mail providers / businesses care about ( to some extent anyway, and 
some more than others ), because they get shut off if it gets too low. 
( other people won’t take their mail ).

much of my time?  It feels like tilting at windmills, but, it would be

What does the domain status above mean?  That the status is unavailable

Email & Spam

2023-03-08 Thread Bruce Labitt

Seems to be an uptick in spam received lately.  Doesn't seem that my ISP 
is on top of it.  In the past 48 hours have received at least three 
dozen spams from similar parties.  Many seem to be coming from *.store 
domains.  I haven't knowingly ever visited one of these domains.

I don't think I want to run my own email server - mostly because 1) I 
really don't know how to set one up, and 2) it sounds like a bit of work 
to maintain.  Of course, I could be wrong, which is why I am asking.

I did a whois, and due to privacy cr*p, there's no longer a way to get 
to the registrants.  I can see why this might be, but it does make it 
harder to report people.  I did report a couple of domains as spammers 
to godaddy, since I *think* they were the registrar.  This really 
doesn't seem kosher to me, since godaddy gets revenue from the 
spammers.  I also reported a domain or two to my ISP.  Things have 
slightly slowed down, but I am not holding my breath.

In my wife's case, one or more of her acquaintances (with Windows 
computers?) have had their accounts compromised or information stolen, 
and she has been super subscribed to what seems like dozens and dozens 
of spamming lists.  Her spam folder on her phone receives may hundreds 
of emails a day - it's really out of control.  How can we get out of 
this mess?

Anyways, are there any practical ways to get a better handle on this? 
Looking for some ideas.  Thanks for any and all suggestions.  I hope 
this would be a topic of interest to others on this list.  If for no 
other reason to share what worked and what didn't.

Book or online source on modern Linux system files and organization

2022-12-21 Thread Bruce Labitt

Feeling like a bit of a fossil and not knowing what files do what, or 
where things are located.  Need to fix an obnoxious problem with a 
keyboard and realize I just don't know even how to investigate this 
anymore.  What are recommended sources for a modern overview of system 
files, purposes and organization?

Think my laptop now believes my Logitech keyboard is the default 
keyboard.  This is bad, because it has a different number of keys and 
the mapping is different.  This a royal pia.  I am typing with a mouse.  
Even the space bar doesn't work.  Practically it makes a laptop into a 
desktop system.  I don't even know where to start since a lot of the 
Linux cheese moved, in the past 10 years.

System76 Oryx 6 Pro laptop.  POPOS 22.04.

Any tips or pointers to well written overviews on the modern 
organization would be appreciated.  Perhaps I could learn enough to at 
least know the correct search terms.

TIA, Bruce

Strangely, it worked after a second time - after I deleted the empty 
authorized_keys.  Was able to ssh in to the git@remote-server using the 
passphrase, and checked there was an entry in the authorized keys 
corresponding to the remote computer.

Back to the git issue.  At least there's some progress :)

I am getting permission denied.  Here's the question.  I am logged in as

adduser, I forgot to use the -m flag, so there's no home/git on the 
remote.  But there is a /home/git on the server.

setting up my own git server

2022-10-09 Thread Bruce Labitt

I am trying to accomplish this and am running into a couple of 
problems.  Following the instructions at: 
https://www.linuxfoundation.org/blog/blog/classic-sysadmin-how-to-run-your-own-git-server


Specifically, the command $

cat ~/.ssh/id_rsa.pub | sshgit@remote-server  "mkdir -p ~/.ssh && cat >>  
~/.ssh/authorized_keys"

fails  with the message bash: /home/git/.ssh/authorized_keys: Permission denied

Is this because the user git is not a sudoer? Strangely, the directory 
.ssh was created, but nothing else. I tried this twice. The first 
failure message was


bash: /home/git/.ssh/authorized_keys: No such file or directory

Then I sudo touched the file into existence.  The second error was

bash: /home/git/.ssh/authorized_keys: Permission denied

The article leaves out some details, assuming one is a master of the 
art.  It does not tell you what user you are when you are ssh'd in.  Are 
you logged in as user git in both cases?  If so, why is he changing to 
/home/swapnil to create his directory?  Am I to create 
/home/bruce/project-1.git?


Is there a better article to set up password less ssh login?  And maybe 
setting up a master git repo?  I have a local git, but really want to 
have a dedicated server just do the repo.  Any hints or guidance would 
be helpful.  TIA.  I have multiple satellite computers that need common 
git managed code.

 Is there some way to extract the photos from google with the dates intact?

 If not, can the files be parsed for their date taken and the attribute
 date reset to the taken date?  Say one were to do this in python, it

Re: Debugging linux crashes

2022-06-14 Thread Bruce Labitt

The USB mode changes during the flashing, wonder if that is what is 
confusing the kernel or not. During the "wake up the Teensy bootloader 
mode", I think the USB is talking to /dev/hidraw4, once the device is 
programmed, the Teensy (M7) appears as /dev/ttyACM0.  Maybe the kernel 
can't handle a lot of these transitions, falsely thinking there's an 
error, or there's a goofy hard limit programmed in the kernel...


Can anyone think of why USB transactions or USB mode switches might trip 
a trip into lala land?

Kernel 5.15.0-37-generic does not crash.  Kernel 5.18.2 also crashes, 
only if I use TyCommander, but not necessarily during a USB flashing.  
I had 5.18.2 crash while I was using Firefox, but while Arduino IDE

Now running on 5.15 and things are stable.

I know nothing about kernels and stuff like this.  Been forced into 
it.  An average Joe like me shouldn't have to deal with this kind of 
thing.


TyCommander works fine on an RPI4 running Raspberry Pi OS 64 bit, 
which as I understand it is a Debian derivative.  The kernel is 
5.15.30, according to Wikipedia.  Not looking forward to an update of 
that kernel.


I have no idea how to make a minimal dying example for any developers...

Pop-OS-64 bit.  22.04.  Fresh install over existing Ubuntu 20.04 LTS.

I need to reboot the computer to get the kernel stuff.  Will 
followup with uname -a.


Problem occurs when using USB to program Teensy 4.1 
microcontroller.  Active programs at time of crash = Arduino IDE V 
1.8.19

Re: Debugging linux crashes

2022-06-13 Thread Bruce Labitt

FWIW, this total system crash has been isolated to the kernel.  Kernel 
5.17.5-76051705 crashes.  Which was pushed out to apt on, guess what, 
May 26, 2022, the date my computer went to hades.


Kernel 5.15.0-37-generic does not crash.  Kernel 5.18.2 also crashes, 
only if I use TyCommander, but not necessarily during a USB flashing.  I 
had 5.18.2 crash while I was using Firefox, but while Arduino IDE and 
TyCommander were active.


Now running on 5.15 and things are stable.

I know nothing about kernels and stuff like this.  Been forced into it.  
An average Joe like me shouldn't have to deal with this kind of thing.


TyCommander works fine on an RPI4 running Raspberry Pi OS 64 bit, which 
as I understand it is a Debian derivative.  The kernel is 5.15.30, 
according to Wikipedia.  Not looking forward to an update of that kernel.


I have no idea how to make a minimal dying example for any developers...

the model of machine, for example.  List major components with model
or type (CPU model and speed, RAM size, type and size of storage,
model/type video controller, etc.).  You mention distribution and
version, which is good, but also please provide kernel version.  Also
include steps to reproduce (when it happens, when it doesn't),
commands you've tried, places you've looked for files, error messages
received, etc., etc.

I know you've been around long enough that you've seen plenty of bug
reports and knowledge base articles and the like.  Follow their

Re: Debugging linux crashes

2022-06-05 Thread Bruce Labitt

, date = 2021-02-07

The last error I get is related to USB, then the system hard collapses.  
Nothing else happens.  syslog got a string of \00\00... to it.
dmesg shows the same time for the reboot, the same USB message and 
nothing else.

This has been pretty frustrating.

Debugging linux crashes

2022-06-05 Thread Bruce Labitt

I am experiencing severe Linux crashes, due to some unknown causes.  
They appear to be related to the use of Ty Commander and programming a 
Teensy 4.1 in the Arduino IDE environment, but I am not positive.  All I 
know at the moment, is that the screen freezes and is unresponsive to 
keyboard or mouse inputs.  The freeze lasts about 10 seconds and the 
laptop computer simply powers off.  The error seems to be quite 
repeatable.  It may or may not have started after a Nvidia graphics 
update.  I do know after a normal system update in Ubuntu 20.04 on May 
26, my system has been subject to this problem.

I have purged nvidia drivers and reinstalled them.  Didn't matter.  
Syslog and journalctl really didn't seem to show anything interesting, 
at least to my unsophisticated gaze.  Have been a wits end.  In the 
interim, I moved a lot of my "life" off the laptop onto an RPI4B-8GB 
running Raspberry Pi OS 64 bits.  Been a difficult transition, 
recovering my capabilities, computing-wise.

I backed up my whole laptop, and decided, perhaps insanely, to do a 
fresh install of Pop-OS 22.04.  With the base install, I ran into the 
same darn wifi issue that initially plagued me with this laptop.  After 
2 days of seaching, I found the answer to the slow and constantly 
rebooting iwlwifi card was to set powersave =2, which for some darned 
reason means powersave is off!  I am amazed that this issue still exists 
this day and age, I found mentions of it over all Linux distros.  The 
issue is the wrong microcode is being sent to the wifi adapter, and the 
adapter kernel panics when it receives illegal commands from the Linux 
OS.  You can see it in the syslog very clearly.  I changed the powersave 
to 2, and the wifi adapter seemingly works fine now.  This is the Intel 
WiFi 6 AX200/AX201.

Anyways, even with this brand new installation, and fixed wifi, my 
computer crashes with the combination of Arduino IDE 1.8.19, Teensyduino 
1.56, and Ty Commander 0.9.7.

However, I found that if I use Arduino IDE, and Teensyduino 1.56 only, I 
have been able to program my Teensy 4.1 without crashing. Unfortunately, 
I'd like to use Ty Commander to enable multiple Teensy's to be debugged.

I'm looking for some suggestions on how to proceed.

Is there a way to get or retain more information on system crashes?  I 
don't even know the true cause of the crash yet.  For some reason, I am 
having difficulty opening the kernel log.  Is it a text file?  Or do I 
need a special viewer?  I can open the syslog without issue.  In Pop OS 
I don't see multiple or older versions of logs.  I don't know why.  
Often older logs have a .0 or .1 extension.  The log I want to see is 
not the one created after the boot following the crash, it is the one 
before!

I'm not sure I really have the skills to deal with linux-crashdump.  I 
haven't seen a step by step procedure that I feel comfortable enough to 
proceed with.  The references use a lot of words, re: fiddling with 
grub, not so many pictures, and I don't want to really go there without 
a really complete script. Is this the path I need to take?

I could compile Ty Commander with debug binaries, I just need to type 
out:  cmake -DCMAKE_BUILD_TYPE=Debug ../..

Can I run Ty Commander with valgrind, or something like that would 
prevent yet another total crash, but perhaps capture something useful?

Re: Raid1 Issue on RPI4

2021-05-29 Thread Bruce Labitt

Seems to be a NVME case related thing. Perhaps my clamping arangement 
shorted out a connection.

I have the disks up.  However, the nvme disk is reporting as /dev/sdd 
now, not /dev/sdb.
This is dumb.  mdadm.conf has configured the array as:

ARRAY /dev/md0 level=raid1 num-devices=2 metadata=1.2 name=rpi4:0 
UUID=82415afc:85be4701:d47937be:cdb8b4e8
    devices=/dev/sdb1,/dev/sdc1

Is there a way to make the devices by UUID so this always works?  If so 
how do I get the uuid of the individual disks?
Right now, due to the RAID1 sdc and sdd have the identical UUID.
But,

$ sudo mdadm --detail /dev/md0
/dev/md0:
    Version : 1.2
  Creation Time : Wed May 26 09:47:08 2021

     Number   Major   Minor   RaidDevice State
    -   0    0    0  removed

Is there a way to get back to a working 2 device RAID1 array?
There's nothing of any value on the array at the moment.  But I'm really 
not too happy about a disk disappearing - this doesn't seem robust.

Raid1 Issue on RPI4

2021-05-29 Thread Bruce Labitt

So I got the raid1 array running on the RPI4.  Today, I tried to add a 
sub directory to the array.  Apparently something bad happened and one 
of the disks disappeared.  When this happened there was some kind of 
major upset, as the OS stopped functioning, like it no longer knew where 
commands were located.  sudo, stopped working.  I could type in commands 
via ssh and see the characters, but the command interpreter didn't 
function correctly.  I got a bash message saying it couldn't find the 
command.  Could not establish another ssh session with the RPI.  At that 
point, I pulled the power.

Upon a normal reboot, I find sdb is missing.  md0 is still intact with 
just sdc1.  I'm not sure how mkdir would cause this, but...

$ sudo mdadm --detaill /dev/md0 states there are 2 RAID devices, but 1 
total devices.  1 Active device, 1 working device, 0 failed devices, 0 
spare devices.  Disk0 state is removed, and Disk1 state is active sync 
/dev/sdc1

Assuming I can get sdb back, how do I get it back in the array? Just $ 
sudo mdadm --manage /dev/md0 --add /dev/sdb1 ?  Is there a way with UUID's?

Weird that the NVME disk sdb has just disappeared.  Even after a reboot 
it isn't present, even though the idiot light is on.  fdisk doesn't show 
it.  parted allows me to select it but print shows info on sda?  parted 
will select and print data on sdc.

Is there anything that can be done to 'rescue' the nvme disk sdb?

Re: Have suggestions for a "roll your own file server"?

2021-05-28 Thread Bruce Labitt

fstab updated.  Just needed to use UUID=, not PARTUUID.  I do notice 
significantly long boot times now, guess it takes a while to get the 
RAID1 up.  Used to take 5 seconds to be available to ssh into, now takes 
about 45 seconds to a minute.

I think I'd like the server to initiate the backup.  So, first, I think 
I should set up ssh keys.  So the client/server (who's on first!) 
confusion rears it's ugly head.  For the server (the storage center) to 
contact the client (one of several laptops), I need to use the client's 
public key?  So I need to create the client's key pair?  Once I have the 
client's public key I use the ssh-copy-id command from the client to the 
server?

Now if I want no passwords sent what do I do?  (Just keys).  I didn't 
quite understand the example on 
https://www.howtogeek.com/424510/how-to-create-and-install-ssh-keys-from-the-linux-shell/
 
It seems one can have the passphrase last a session, how to get it to 
remember to use the clients' keys in "perpetuity"?  If there's a 
problem, how to revoke the keys?

Have some questions on rsync --backup option, is there a way to have 
like a rotating backup, say a weeks worth?  I don't understand the 
difference between --backup and just using -avr, what is the advantage 
of --backup?  The rsync man file was not clear to me (today).

Thanks

Sorry, had to truncate the message - gnhlug server complained about it

Re: Have suggestions for a "roll your own file server"?

2021-05-26 Thread Bruce Labitt

Finally back to this.  Built a stack of metal plates that house my RPI4, 
a boot SSD, a 1TB RAID1 array, and both active and passive USB3 hubs.  
Machined parts so everything is bolted and clamped down.  Have a PWM fan 
that cools the RPI4 proportional to load that runs under systemd.  
System boots from SSD.  (No SD card.)  It's kind of a brick sh!thouse, 
but it's sturdy.  Have created the RAID1 device - or it will be finished 
in 45 minutes.  It is still syncing.

Now I'd like to add the md0 device to /etc/fstab.  The example I see is 
with the device name.  From https://www.tecmint.com/create-raid1-in-linux/

/dev/md0    /mnt/raid1    ext4 defaults    0 0

I've read it is better to use the UUID.  Is the following the correct 
syntax?

PARTUUID=my_complete_md0_UUID /mnt/raid1    ext4    defaults  0 0

where my_complete_md0_UUID comes from
$ lsblk -o UUID /dev/md0

Does one need to use tabs in fstab, or are spaces ok?

Once I figure this out - I have to figure out some rsync magic.  Is it 
better for the server to initiate the rsync, or the remote devices?

After all this I have to make another one.  That shouldn't take as long 
as the first time!  For some pictures of the hardware build see

Unless you build multiple Ethernet or WiFi or LTE modem
connections your networking will still be the slowest thing.

You do not need huge amounts of CPU power, or huge amounts of RAM.

My basic point is that if you stick with simple RAID (like
mirroring) but also set up a unit that is remote from your own
home you could protect your own data from fire, flood and
theft to a reasonable level and even protect your friend's
data by backing up their data to your device.

Add snapshots as suggested by Tom Buskey,perhaps encryption of
file systems and data-streams and you can have a rather
simple, server where you learn a lot by planning it out and
setting it up rather than buying an "off the shelf" solution
or simply using a "web backup".

And good catch on the USB power supply.

Well technically, I'd think it was VOIP.  All my service comes over

Thanks for the embarrassingly concise answer.  It is greatly 
appreciated.  Can you explain the syntax of the 2nd argument?  I haven't 
seen that before.  Where can I find further examples?

What astounds me is re.search allowed my 1st argument, but re.sub barfed 
all over the same 1st argument.

Python re to separate some data values

2021-04-28 Thread Bruce Labitt

If someone could suggest how to do this, I'd appreciate it.  I've 
scraped a table of fine thread metric screw parameters from a website.  
I'm having some trouble with regex (re) separating the numbers.  Have 
everything working save for this last bit.

Here is a sample string:

r1[1] = ' 17.98017.87417.65517.59917.43917.291'

I'm trying to separate the numbers.  It should read like this:

17.980, 17.874, 17.655, 17.599, 17.439, 17.291

There's more than 200 lines of this, so it would be great to automate 
it!  Each number has 3 digits of precision, so I want to add a comma and 
a space after the third digit.

re.search('(\.)\d{3,3}', r1[1]) returns
 so it found the first instance.

But, re.sub('(\.)\d{3,3}', '(\.)\d{3,3}, ', r1[1]) yields a KeyError: 
'\\d' (Python3.8).  Get bad escape \d at position 4.

And, if one adds enough escapes to avoid a KeyError, the function 
actually does nothing, since Out[117] is the same as r1[1]

In [117]: re.sub('(\.)\\\d{3,3}', '(\.)\\\d{3,3}, ', r1[1])
Out[117]: ' 17.98017.87417.65517.59917.43917.291'

I've looked in https://www.w3schools.com/python/python_regex.asp, 
https://docs.python.org/3/library/re.html, 
https://docs.python.org/3.8/howto/regex.html, 
https://www.guru99.com/python-regular-expressions-complete-tutorial.html#2, 
https://www.makeuseof.com/regular-expressions-python/, and 
https://www.dataquest.io/blog/regular-expressions-data-scientists/ and 
https://realpython.com/regex-python/

Is there a way to do this with re?  re.finditer seems to work ok, it 
finds all the indices correctly.

In [121]: it = re.finditer('(\.)\d{3,3}', r1[1])
In [122]: next(it)
Out[122]: 
In [123]: next(it)
Out[123]: 
In [124]: next(it)
Out[124]: 
In [125]: next(it)
Out[125]: 
In [126]: next(it)
Out[126]: 
In [127]: next(it)
Out[127]: 

Suppose I could brute force it at this point, but one would think 
re.sub  should work, if the magic flooby dust was appropriately 
sprinkled about.  I'm clearly missing something important.  Anyone got a 
hint?

Re: Trying to figure out if I have a bad NVME device

2021-03-23 Thread Bruce Labitt

It would seem there was an issue with the socket on the nvme enclosure -
actually the WD NVME connector is slightly differently dimensioned than the
Samsung.  I swapped housings and I got the WD NVME to be recognized.  Now
it can be partitioned.
I'm in the midst of partitioning with gparted and selected gpt over MBR.
Now to create a new partition.  I'd like to use the whole 1TB as a
partition.  It's defaulting to free space preceding = 1MiB, free space
following = 0MiB.

What does one use as a Partition name?  What is a standard convention?
What about label?  I am selecting EXT4 as the file system.  Any advice?
Thanks.

Re: dd cloning a Win10 HDD to SSD

2021-03-23 Thread Bruce Labitt

Worked on the first boot.  Booted in maybe 10 seconds!  Ran CrystalDiskMark
on the before and after.  It's the random 4k stuff that really makes a
difference.
The Samsung EVO860 SSD is a minimum of 77x faster on random write and 100x
faster on random read as compared to the WD HDD.  (RND4K, Q1T1).  It's like
a totally different machine.  Hope windows won't complain later.

So... for the record, dd did work to clone a Win10 disk to a SSD.  It
copied over all 5 partitions, including the MS secret partition and EFI,
plus whatever nonsense partitions that Dell put on this disk.  Will check
to see if all this survives a reboot...  Yes!
Well, hot diggity dog!  At least for this disk pair, dd worked great!  No
BS, no FUD, it just worked. :)

Re: dd cloning a Win10 HDD to SSD

2021-03-23 Thread Bruce Labitt

I was 20 minutes into dd when I noticed that the disks were mounted.
Aborted dd.  Unmounted both disks and restarted dd.  I'm at the tail end of
the run, and hoping it completed without errors.  If it barfs I may try
ddrescue, the gnu version.

The old disk has really bad random access rates.  It's like less than 0.5
MB/sec for random 4k access.  On Win10 it's incredibly slow.

FYI, the only reason I even turned on this sorry excuse of a laptop was the
NH VINI website would not render the Covid-19 vaccine registration site
correctly in Chromium, Chrome or Firefox in Linux yesterday.  It was
impossible to fill out the form.  After 3 hours of really slow windows
updating, I could install the latest version of Chrome on Windows 10.  Then
and only then could I register.  It took 6 hours to update the laptop to be
current.  So despite the fact that I don't use Win10 regularly, it was
useful yesterday.  The laptop experience was so painful that I decided to
replace the HDD with a spare SSD.

The State of NH made the registration forms only work with the latest
version of Edge, Chrome and Firefox.  Unfortunately, yesterday, in Linux,
the versions were slightly older.  For Firefox the Windows version was
86.0.1, and in Linux it was 86.0.  Today I noticed that 86.0.1 is available
for Linux.

Any ways, that's why I'm attempting this.  If for some odd reason I have to
use the Win10 laptop again maybe it won't be so painful.  20 minute boot
times are just awful.  An SSD should bring it to 20 seconds at least
according to a disk benchmark tool I ran.

Personally, I hope my real laptop gets repaired.  It croaked after a couple
of months.  Brand new.  In the interim, I am dd'ing with a RPI4, as that's
all I have.  The RPI boots direct from SSD and is overclocked to 2Ghz, so
it's tolerable, but not speedy.

Thanks for the update.  The HDD is a WD.  If dd fails, I may try the
Acronis.

Re: dd cloning a Win10 HDD to SSD

2021-03-23 Thread Bruce Labitt

It would seem clonezilla requires linux x86* to run.  Unfortunately I'm on
a RPI4, as my "real linux laptop" is being repaired.  Seems I'm stuck with
dd or gddrescue.
At the moment it has taken 6571s to copy 677GB...  hope this works.  Less
than an hour to go, I hope.

In my case the disks report to be the same size in lsblk.
fdisk -l reports the hdd is 1000204886016 bytes, and the sdd
is 1000204886016 bytes or exactly the same size.
Guess I will try dd.  Fingers crossed...

Is there a compelling reason to use ddrescue over dd for this?  Is gnu
ddrescue the preferred choice of the ddrescues?

Or is this a fool's errand?

dd cloning a Win10 HDD to SSD

2021-03-22 Thread Bruce Labitt

Have this excruciatingly slow Win10 HDD I'd like to clone to SSD.  Reading
about how to do this leads me to dd as a way to clone the disk.  The disks
are close in size.  According to lsblk, the HDD sdb is 931.5GB, and the SSD
sdf is 931.5GB.

sdb has 5 partitions on it.
1) EFI  500MiB
2) MS reserved partition  128MiB
3) OS "basic data" partition 918.07GiB
4) WINRETOOLS 852MiB
5) Image   11.56GiB

sdf has stuff on it, which I presume will be wiped out by dd.

Since the sizes are "equal", can I just # dd if=/dev/sdb of=/dev/sdf bs=1M
status=progress and be done with it?  Is there anything else that I'd need
to do to get it to boot?

Trying to figure out if I have a bad NVME device

2021-03-21 Thread Bruce Labitt

I have a USB3.2-PCIE NVME adapter (actually have 3 of them) using the JM583
chip.  I also have a Samsung 970 EVO Pro 1TB NVME and recently bought 2 WD
1TB NVME cards.

I cannot get a WD NVME to be recognized by the OS.  I haven't tried the
second WD NVME as I am leaving the package unopened.

lsusb reveals the JMicron adapter so I have the ID
fdisk -l and lsblk do not show the WD device, nor the JM adapter
The WD disk has never been partitioned or formatted.

sudo dmesg | tail -n 50 shows some sort of issue.

However, the same adapter works fine using the 970 Pro NVME device.  On the
970 I have the complete backup to my laptop.  The 970 auto mounts.
Is it possible that UAS doesn't work for the WD NVME?  Or is the WD NVME
defective?  Or the WD NVME hasn't been prepared properly?   My google-fu
seems to be weak - it's been difficult to find appropriate information.
Hope it's just that I missed a step...
I have heard of blacklisting the UAS driver, but it seems odd the adapter
works reliably for the 970 but not the WD.

I'd greatly appreciate a hint.  Currently running on an RPI4B-4GB Raspberry
Pi OS 32bit since my new laptop bit the dust.  The laptop has been sent
back for repair.
Thanks for your patience...

Re: RPI HW PWM fan control

2021-03-20 Thread Bruce Labitt

Apparently one cannot control both pwm outputs simultaneously.  When one of
the pwm outputs was disabled, the service does work correctly after a
reboot.  The bcm2835 driver which is used by this project apparently
silently fails!  It sure would be nice if the applet logged this
somewhere.  This was a devil to find...  There was an oblique reference to
silent failing in the bcm2835 library documentation, which gave me a clue.

RPI HW PWM fan control

2021-03-19 Thread Bruce Labitt

I found a project on
https://gist.github.com/alwynallan/1c13096c4cd675f38405702e89e0c536 for a
hardware controlled pwm fan for the RPI4.  This should have low resource
usage, as compared to software controlled pwm.  I don't have a Noctua type
pwm fan, but I made a simple circuit with a resistor, a transistor and a
flyback diode to drive a brushless DC motor from the GPIO pin.  The
circuit, cobbled together on some perf board, works great.

This project works, but doesn't.  By that I mean, if one makes and installs
the program along with a systemd service it works.  However, the fan
control does not survive a reboot.  More accurately, the service is
relaunched after boot - I can see it with # systemctl | grep pi_fan_hwpwm,
but the actual pin is not being controlled.  The SW thinks it is
controlling the pwm pin output, but there is NO physical control of the
pin.  As the core temp gets hotter and hotter the PWM duty factor
increases, as designed, but no signal is at the GPIO#18 pin.

The pi_fan_hwpwm.service is
[Unit]
Description=Hardware PWM control for Raspberry Pi 4 Case Fan
After=syslog.target

[Service]
Type=simple
User=root
WorkingDirectory=/run
PIDFile=/run/pi_fan_hwpwm.pid
ExecStart=/usr/local/sbin/pi_fan_hwpwm
Restart=on-failure

[Install]
WantedBy=multi-user.target

Multi-user.target.wants has pi_fan_hwpwm.service in its directory.  The
service does start.  However the actual control of the pin is somehow being
prevented.  Even if I stop and start the service, the pin is not controlled.

I've turned off i2c, spi and audio in /boot/config.txt  There's some
"mumbling" about doing things like this, both in the source of
pi_fan_hwpwm.c and in the header of bcm2835.h.

This project includes bcm2835.h to control the pwm.  If I use the example
file found in bcm2835-1.68/examples/pwm/pwm.c and compile it, it controls
the fan.  If I then stop and start the fan service (after running ./pwm
once) the fan pwm service now controls the fan physically.  Comparing the
code in pwm.c and pi_fan_hwpwm.c reveals similar structure and
initialization.  Have to say, this has been perplexing.

Besides giving up, which I have seriously considered, anyone got any
suggestions to make this work?  Was hoping to use the HW controlled fan on
my RPI4 NAS.

rsync question

2021-03-09 Thread Bruce Labitt

A maybe not so smart rsync question...

If one uses rsync -avz src/bar  /disk2will that copy over everything
from src/bar and create a directory bar on disk2?  What if src/bar has
other users or root?  In other words, does the -a mean that it will

Yet you might think that since many, many people pay off mortgages or pay
off mortgages on sales of property every single year that they might have
it down to a science by now.   It is not like I am the first mortgage that
has been paid off in the past 30 years..

Maddog, I totally agree with you.  I was astonished and more than a little
annoyed that it took so long.  You'd think it was the first time (every
time!).  Apparently the banks aren't too innovative in this respect...

Have suggestions for a "roll your own file server"?

2021-03-08 Thread Bruce Labitt

For the second time in 3 months I have had a computer failure.  Oddly, it
was a PS on the motherboard both times.  (Two different MB's.)  Fortunately
the disks were ok.  I'm living on borrowed time.  Next time, I may not be
that lucky.

Need a file server system with some sort of RAID redundancy.  I want to
backup 2 main computers, plus photos.  Maybe this RPI4 too, since that's
what I'm running on, due to the second failure.  If this SSD goes, I'm
gonna be a sad puppy.  This is for home use, so we are not talking
Exabytes.  I'm thinking about 2-4TB of RAID.  Unless of course, RAID is
obsolete these days.  Honestly, I find some of the levels of RAID
confusing.  I want something that will survive a disk failure (or two) out
of the array.  Have any ideas, or can you point me to some place that
discusses this somewhat intelligently?

Are there reasonable systems that one can put together oneself these days?
Can I repurpose an older PC for this purpose?  Or an RPI4?  What are the
gotchas of going this way?

I want to be able to set up a daily rsync or equivalent so we will lose as
little as possible.  At the moment, I'm not thinking about surviving fire
or disaster.  Maybe I should, but I suspect the costs balloon
considerably.  I do not want to backup to the cloud because, plain and
simple, I don't trust it to be fully secure.

Thanks for any and all suggestions.

If my experience is a guide, you have a few more months to go.  Once we
paid off our mortgage it took almost 6 months to clear everything up.
(That was in late 2018)  What you probably aren't realizing is that they
have to hunt down your paperwork.  Your note was probably transferred to
dozens of investors who bought and sold paper.  They are tracking it down
by going through the chain of possession.  The days of your bank holding
your mortgage papers in the local vault are gone forever.

But yeah, late a day, they'd call you...

It would seem you have learned some of this the hard way.  And you are
indeed scaring me a bit.  Not sure what to do differently, however.  What
I'm hearing is properly dealing with time is hard and ugly.  I've
experienced some of this already.

I have been warned.  But, I still have to get on with things...  Can't
change the whole world, for that matter, I can't change how the cards are
written either.  So I'll have to put in (more than a few) tests to ensure
that I don't jam things up.

Thanks for passing on some of these pearls of wisdom.  I mean it.  When I
mess up, I'll remember, oh yeah, I was warned about that.  Next thought
will be, "Gosh, how am I going to fix this?"

Are there any "relatively" local PySIG's any more?

2021-03-05 Thread Bruce Labitt

Been reminiscing a bit lately and thought about the PySIG group we had 
in the area.  Stumbled across the Boston Python Users Group.  Is that 
the closest one?  Are there any others not on the Python Software

Jeesh, don't even know why I'm asking about locality these days - most

Been missing my python meetings...  Learned a lot from them.

Re: Kind of puzzled about timestamps

2021-03-05 Thread Bruce Labitt

That was somewhat comical.  Yeah, been trying to keep everything with 
respect to UTC.  It can be a little difficult at times, as it's easy to 
goof up and fall in to quite a few time trap holes.

One of the more difficult things has been indexing into the time array.  
I've been using numpy's timedate64 and timedelta64 but occasionally 
still get tripped up. Handling time is complicated.  Fortunately, all 
that I care about for this project is relative time.  Start time, end 
time and time is "linear" in between.  According to the the youtuber, 
even that's not guaranteed if one spans the new year and we need a leap 
second!

These files are written by commercial closed box machines (medical

"UT" was me being lazy.  (Too lazy to type the extra character...)  I 
don't have any code with explicit timezone stuff in it.  Have to agree 
it's a good idea to keep time in UTC, to avoid 'many' of the headaches.  
Nonetheless, it's easy to get confused about all this, especially if

Weird, it is just the 5 hours between UT and EST.  The files are 
generated on a non-linux embedded machine.
If I create a file on my pc, then the TZ information is present and the 
time is set.  ls reads it correctly.


This time stuff can get confusing.  As you were.

Actually, what is returned by my script is at least sensible,
given that 20210225_224141_BRP.edf started on Feb 25th and
ended recording at 2:17am on Feb 26th.  I know this because I
can see the data on a separate program.
20210226_022133_BRP.edf started on Feb 26th at around 2:21am
and terminated at 6:49am.  BRP files are written to
continuously at a 25 Hz rate all evening.  What makes no sense
whatsoever is what *ls* is reporting.

Do *ls* and python3 use different definitions of "last modified"?

Guess I can keep going, but I really was surprised at the
difference between methods.  Default for ls is "last
modified", at least as reported by man.  ls's last modified
just isn't correct, at least on Ubuntu 20.04.2

Is this a quirk?  Am I doing something wrong?  Some kind of
voodoo definition of "last modified"?  What does Linux say
"last modified" really means?

FWIW, I am coming up to speed on processing these edf files to
help out on an open source project.  Been working on some data
analysis tools.  As an aside, biological data is very messy. 
It's been a treat to work on this as it's forced me to dust
off the mental cobwebs and work on a problem that can help a
lot of people.

Good point.  I'll check that.  Logging machine was set to local time EST.
But it does have a wireless link, maybe it set itself internally to UT.

Kind of puzzled about timestamps

2021-03-04 Thread Bruce Labitt


This is an odd question.  It involves both python and linux.

Have a bunch of files in a directory that I'd like like to sort by 
similar names and in time order.  This isn't particularly difficult in 
python.  What is puzzling me is the modified timestamp returned by 
python doesn't match whats reported by the file manager nautilus or even 
ls.  (ls and nautilus are consistent)


$ lsb_release -d Ubuntu 20.04.2 LTS
$ nautilus --version  GNOME nautilus 3.36.3

$ python3 --version Python 3.8.5

$ ls -lght

total 4.7M

Do *ls* and python3 use different definitions of "last modified"?

Guess I can keep going, but I really was surprised at the difference 
between methods.  Default for ls is "last modified", at least as 
reported by man.  ls's last modified just isn't correct, at least on 
Ubuntu 20.04.2


Is this a quirk?  Am I doing something wrong?  Some kind of voodoo 
definition of "last modified"?  What does Linux say "last modified" 
really means?


FWIW, I am coming up to speed on processing these edf files to help out 
on an open source project.  Been working on some data analysis tools.  
As an aside, biological data is very messy.  It's been a treat to work

Question about ssh key generation

2021-02-16 Thread Bruce Labitt

Gitlab is asking for ssh keys now.  Is there a recommended type of key 
these days?

man ssh-key gives me the following choices:  dsa | ecdsa | ecdsa-sk | 
ed25519 | ed25519-sk | rsa

Which should I choose?  Which ones offer the longer/longest key length 
(best security?)

Sorry for the simplistic question, not done this before.  Any insight 
would be helpful.

Help me fix this annoying RPI4 Buster printing problem

2021-01-08 Thread Bruce Labitt

At the moment I'm on an RPi4 running Raspberry Pi OS.  My laptop died 
recently.  I'm trying to figure out this OS works.  Have to say, it's 
been painful in many ways.  One is that the RPI is slow...  It will be a 
little while before I get a replacement laptop, so I have to deal with this.

Although I have configured a network printer (running on CUPS server on 
an RPi2) some apps on my RPI4, like, GIMP, gpaint, and LibreOffice seem 
to retain former and incorrect printers.

My GoogleFu seems to be terrible.  Can't seem to find a way to purge 
these old settings from showing up.  There has to be a way to do this!

I've found this experience to be pretty darned exasperating.  I find 
lots of apps, including gpaint, don't just work on RPI4 Buster.  Doing a 
print, or a print preview from gpaint should NOT cause the app to fail 
and terminate.  Especially if the network printer actually is configured 
correctly.  I can print a test page just fine.

Where are system wide print settings managed?  File names and 
directories?  Does gpaint have a shadow set of printer settings? Where 
are they stored?

Re: SMART data & Self tests, not sure if my SSD is on it's last gasp

2021-01-06 Thread Bruce Labitt

To put some bounds on this, I'm currently looking at an Oryx Pro.  I have
it tricked out to $2100.  i7-10875H, 32GB 3200MHz RAM, RTX2060 6GB, 1TB
NVME seq. RD 3500MB/s, seq WR 3300 MB/s, 15.6" display 1080p.  Seems to be
the best combination of stuff I can find for the price.  Can a standard
make laptop beat that and be relatively painless linux compatible?

Re: SMART data & Self tests, not sure if my SSD is on it's last gasp

2021-01-06 Thread Bruce Labitt

It would be a lot easier if this was a desktop.  I had a PC supply
capacitor explode once.  That was exciting, as I was in the room at the
time.  Boom!  Lots of smoke.  One of the high voltage electrolytic caps
popped.  Replaced the power supply and was good to go again.

Laptops, especially 7 year old ones, probably won't be able to be
repaired.   Well, this laptop went out with a whimper...  Wouldn't surprise
me if it was a bad electrolytic cap.  Wasn't there a bad run of them a
decade or so ago?

Checked the media, both are readable using the RPI4.  Seems like the power
supply is failing.  It's cycling on and off even with no media, dvd, or
drives.  I think this is a dead parrot.

Well, that was fun.  Uh, not really.

Guess I need to go computer shopping.  It was an i7, 32GB RAM, 17" screen.
It had a nvidia GPU so I could play with CUDA.  What's out there that's at
least as good performance wise and not a PIA to convert to linux.  It was a
Bonobo Extreme 6.  At the time it was pretty high end.  My BonX6 was a boat

Re: SMART data & Self tests, not sure if my SSD is on it's last gasp

2021-01-06 Thread Bruce Labitt

I yanked the battery, and all the disks.  Tried booting with AC power.  And
no usb stick.  I get the same behavior.  Does not respond to F2, F7, or
Func-F2 or Func-F7.  :(  No fan comes on.  If I try the USB stick and power
up, same behavior, except the fan has some activity.  Not looking good...
Guess I could go deeper into disassembly, maybe finding a weird crimped or
mangled cable, or dust filled something or another, but not looking good at
all...  Anything else it could be?  Don't know if this is a clue at all.
Next to last boot (with original disk) was 8 minutes.  Last boot (with
original disk) was 28 minutes .  Is this a sagging or failing power
supply?  What else electrical could it be?

Sorry to bother you, that is, if I haven 't been put on a giant ignore

Found out how to check the whole usb disk.  $ sudo sha256sum -b /dev/sdx
Sudo was required.  Hope to be back and running soon...  Sorry for all the

System76 thinks it's the ssd.  Machine strangely got locked up while trying
to start the arduino IDE, forcing me to power off the laptop.  Took 28
minutes to boot!  And 12 seconds after handing off to the OS.
So it's time to do this.  I just backed up /home, /opt and /etc.  Anything
else I should do before replacing the disk?  Just checked the sha256sum on
the iso.  How do I check if the USB stick I burned is ok?

Re: SMART data & Self tests, not sure if my SSD is on it's last gasp

2021-01-02 Thread Bruce Labitt

Think it's a driver issue.  Looked in journalctl and there's some errors 
indicated.  One is a video issue, another is some sort of permissions 
issue for user who isn't me.  The permissions issue is with 
tracker-miner, which I find to be highly annoying.  Not quite sure how 
to disable it cleanly with low system impact.

Last fsck was 3 months ago.  Next one is due in 3 months.  So it wasn't 
an overdue fsck...  So I'm not so sure it's disk related at all.

Have contacted system76 and sent them logs.  If I recall correctly, the 
issue seems to be closely related to a driver change (issued by 
system76).  Of course, they are still on break...

Nonetheless, waiting 8-10 minutes for boot is awful.  I don't even think 
my first IBM PC was that slow, even with a boot from floppy disk.

SMART data & Self tests, not sure if my SSD is on it's last gasp

2020-12-30 Thread Bruce Labitt

I think I have a SSD on the way out.  Last reboot took a REALLY long 
time.  Like 30 minutes.  I ran the smart data and self test and the SSD 
passes.  Overall assessment is disk is ok.  I really don't know how to 
interpret what the results are.

I think the disk is in pre-fail based on the smartctl output below

Replace the disk pronto?  Is that what this is telling me?  Or?

I recently copied over many important files to another disk.  And 
downloaded a new OS.  I just hate re-configuring things, and starting 
from scratch, it's such a pain.  Not as painful as a disk crash, but 
close.  I've got loads of stuff I've compiled from source and just 100's 
of things to check or update.  Yes, I'll just have to do it.  It's just 
the week plus of recovery that I'm rebelling against.

Anything else I should do first?  Check something?  Run a test? Any tips 
to make the "recovery" less painful?

Known good wireless Linux Keyboard & Mouse combos?

2020-11-12 Thread Bruce Labitt

My old Logitech K270 keyboard and Performance MX mouse are long in the 
tooth and need replacing.  The paint is worn off several keys and 
sometimes keys either stick or the KB doesn't seem to transmit a 
keystroke.  The MX mouse charging circuit seems to have failed.  If I 
put in a charged NiMH battery it balks.  Red blinking light.  Which 
seems to mean the battery needs replacing, or needs a charge.  Found a 
hack on instructables, but seriously, it's time for a new one.  This one 
is worn.  Yes, I can clean out the KB as well, and have done this 
multiple times, but, it really is time to replace these guys.

Logitech seems to have abandoned their unifying receiver, especially at 
the lower end, which is a shame.  Their stuff worked for me and for a 
relatively long time.

What wireless KB & mouse combos have you found that work seamlessly with 
linux?  I don't need any thing super fancy, just something with no palm 
rests, and not a micro sized mouse.  The little mice are uncomfortable 
to use.  The K270 style layout is perfectly adequate.  Price range is 
$50 and under.

The MK850 claims multi-os friendly, but has the palm rests built in.  My 
desk has a palm rest built in, so the 850 won't work.

Is there any way to actually filter what you see on Amazon?  I swear, 
their search engine is deliberately terrible.  All sorts of irrelevant 
stuff.  20 pages for "linux wireless keyboard and mouse"  First hit is 
wired... Come on...

Re: How does Linux handle DST/ST? It's all about time...

2020-11-10 Thread Bruce Labitt

"Dumb" machine, while actually computer controlled, is closed source.  
No possibility of changing its behavior.
No ssh, no network.  It's a data logger to an SD card.  I have to use 
sneaker net to transport data to my PC.

Other possibility (after a SD card backup) is to change the dumb machine 
clock back to standard time, hopefully without messing any settings up.  
Fortunately I have recorded all the necessary settings.  The dumb 
machine has big warnings to not do such a thing as the instructions warn 
of data corruption.

Probably will end up just changing the dumb clock.  There does seem to 
be a struct with an int called tt_isdst, which should be useful, 
however, not sure the solution would be platform independent.  As I 
understand it, linux uses UTC in the RT clock and Windows uses 
localtime.  How messy.  Oh well, so much for a sw solution, going to 
change the time on dumbo.

Back to what you all were doing... Sorry for the noise.

How does Linux handle DST/ST? It's all about time...

2020-11-10 Thread Bruce Labitt

Still looking at a time related bug.  Wondering how (nowadays) linux 
handles TZ and DST/ST transition.

Does linux embed DST state into TZ?  Or is there a variable with a name 
like "DST"?

I want to set two different machines, one a PC, the other a dumb 
instrument to the same time.  The dumb one doesn't do time adjustment.  
My PC, obviously does.

I want to create a time, on my PC called: mytime = utc + utc_offset.  If 
utc_offset is invariant, then I am all set.  All I can see is (at least 
for ubuntu) there is TZ, which appears to be equal to utc_offset + DST*1.

If there was a variable called DST, I'd be done.  Then mytime = utc + 
utc_offset -DST*1, where DST=1 if now is daylight savings time, or DST=0 
if now is standard time.

Anyone have insight on this?  All I know is that my dumb machine was set 
to DST last month.  My PC is DST corrected.  Half the time, (all during 
ST) the device clock is ahead of the PC clock. Why is this bad - because 
the PC refuses to read files timestamped in the future.  I do not want 
to correct the dumb machine's clock twice a year, as there is documented 
potential for destroying data.  This should be correctable on the PC 
end, shouldn't it?

Re: Simple git question

2020-11-04 Thread Bruce Labitt


Thanks all.  I found that the simple git pull did what I needed it to do.

Built an experimental version of an experimental version...  If anyone 
is interested I'm trying to hunt down a weird DST/ST time bug.  These 
are a bear.  It's really amazing how often people get this wrong.  And 
quite annoying when trying to sync up different machines running 
different software each with entirely different approaches to time shift 
(all of which were actually wrong BTW).  At one point the different 
devices were 2 hours apart, when they should have been within seconds.


Simple manifestation was a failed file read because the time stamp was 
allegedly in the future.  (The time stamp was not in the future!)  Only 
happened once to me and had no tools in place to find it.  Wouldn't you 
know it, error failed to repeat.  If I hadn't saved the debug log, I 
couldn't even prove it happened once.


Not actually thinking I'll trap the error, but if it happens again maybe 
I can learn a little more how to fix it.


Oh and thanks for the list below, very helpful.

Simple git question

2020-11-04 Thread Bruce Labitt

Guys & Gals, sorry for the elementary question.

I have cloned a project that I am interested.  Along the way, I fiddled 
with setting, mostly debug, but none of my changes are important.  I've 
built the project and am using it.  I'd like to re download it from the 
repo again, abandoning any changes that I have made.  A different person 
has merged some changes and I want to try them.

What is the best way to accomplish this?  My head spins with all the 
pushing and pulling.  For some reason I am loath to nuke everything and 
start over again.  Is there a slightly more graceful way to do this in 
git without nuking?

github's man area is not illuminating, instead they talk about all sorts 
of corner case things rather than something this basic.

Thanks all.

As much as I enjoy eating out, the venue was too noisy for a meeting.  
If there's a meeting, it would be good to be able to hear folks.  It was 
difficult to hear people talking only 2 or 3 people away.  My 2 cents.  
What I was able to hear was both interesting and informative, and

Linking problem

2019-09-13 Thread Bruce Labitt

Puzzling over the use of ldconfig.  As I understand it ldconfig can be 
used to rebuild/locate all the shared libraries.  It looks in ld.so.conf 
for the directories to use. In my case ld.so.conf has one line in it:

"include /etc/ld.so.conf.d/*.conf"

I have 3 conf files in ld.so.conf.d.

libc.conf:

     /usr/local/lib

x86_64-linux-gnu.conf:

     /lib/x86_64-linux-gnu

     /usr/lib/x86_64-linux-gnu

i386-linux-gnu.conf:

     /lib/i386-linux-gnu

     /usr/lib/i386-linux-gnu

If I $ sudo rm /etc/ld.so.cache and $ sudo ldconfig -v, I get the message

     /sbin/ldconfig.real: Path `/lib/x86_64-linux-gnu' given more than once
     /sbin/ldconfig.real: Path `/usr/lib/x86_64-linux-gnu' given more 
than once

Why would this happen?  Is this ok?

I haven't gotten to my actual question yet, but this is puzzling me.  
Ubuntu 18.04 LTS, if this matters.  I'm trying to figure out if things 
are ok enough to ask why the linker can't find a file, even though I see 
it in ldconfig.  Maybe what I am asking is how to force a new 
configuration after deleting the ld.so.cache.

Re: Arduino question?

2019-05-04 Thread Bruce Labitt


Hi Paul,

Based on both your suggestion and a few of Bill Freeman's, I found the 
problem.  It basically was a problem with the scope of the #ifndef 
statement.  The problem was that if moreutils was compiled prior to 
RunningMedian, then RunningMedian_h was defined.  Due to an error in 
placement of the #endif statement in RunningMedian.h, the whole body of 
the header file was not read in.  I changed the location of the #endif 
statement in RunningMedian.h so that the body of the header would be 
read.  Problem solved.


So, it was simple... once it was pointed out.  Thanks to you both.

I'll still be coming up to the MakerSpace on Monday.  I'd like to check 
out the setup.  There is one in Nashua, just wondering how the 
Manchester one compares.


Regards,
Bruce

Arduino, does indeed do some funky stuff.  If I could figure it out,

Thanks for the tip on going through the #ifndef's.  It's got to be in 
that neighborhood.  I put in the #ifndef stuff to prevent multiple 
inclusions, which Arduino 1.8.9 IDE does not seem to like, the 
compiler squawked at me when I tried to do that.  What is puzzling me 
is that even if I put the include #include "RunningMedian.h" in the

In both cases, the top of the file states #include moreutils.h.  And 
inside of moreutils.h there is:

#ifndef RunningMedian_h
#define RunningMedian_h

...
#endif

It's got to be simple, it's got to be simple,...  Wish I could see it

I think, I'll come up on Monday.  I haven't been to the Manchester

The Arduinoy parts of the compilation process do some weird things 
behind the scenes to reorder the code before compiling so that it 
actually makes sense. Done with extra .ino files not named the same 
as the project and functions after the main loop in said 
project_name.ino file. Its possible for an Arduino developer/tinkerer 
to declare a function after the two primary loops that use those 
exact functions before actual deceleration because of this behavior. 
Which breaks some expectations of hardened engineers I think. All in 
the interest of catering to new people that would probably be 
frustrated by a strict order of operation. If this behaviour 
rearranges library functions before the "#include ", 
that might give an unexpected result, but that doesn't seem to be

exist. Arduino does ultimately use the gcc compiler, though maybe its 
configured for that switcharoo magic, I didn't write the code, I've

In

the declaration is simply done prior to setup.  Snippet below

#include 

RunningMedian samples = RunningMedian(5);

RunningMedian samples2 = RunningMedian(9);

void setup() {

...

}

void loop() {

use samples here...

}

I'm sure this is trivial for most of you - but I'm both perplexed and
stuck.  If one of you kind souls could help me, I'd greatly
appreciate
it.  I'd even travel to see someone if that would work out better.

Arduino question?

2019-05-03 Thread Bruce Labitt

Can I ask an Arduino/C/C++ question here?  If not, where is a decent 
place to ask?  Full code is just under 50KB (unzipped).

It's a "Variable was not declared in this scope" problem. Basically, I'm 
in over my head at the moment.  I'm not a good structured programmer - 
so let's get that out of the way.  I'm a hack, in the worst sense...

Everything was working... when I had a huge file.  I then decided, wow, 
this is a mess, lets break this up a bit into modules, so that it is 
more supportable and debug-able (for myself).  If anyone is remotely 
interested, it is a homebrew radar based chronograph.  I've got most of 
the pieces working (or at least it worked before I recently busted 
things).  The 100KHz sampling using DMA, the ping pong floating point 1K 
FFT's running in 'real' time, and some display stuff.  Separately, I 
have a live update of a tft screen (320x240) running with the FFT 
output.  I'm running on an ARM M4F processor, but using the Arduino 
IDE.  The Arduino way of doing things is a little confusing to me, to be 
honest.  It hides a lot of things.

Ok, here is the error.

/home/bruce/Arduino/adcdmafftM4bruce/adcdmafft/adcdmafftm4/moreutils.ino: 
In function 'void doMedian(float*, float*, int)':
moreutils:14:3: error: 'RunningMedian' was not declared in this scope

  ^
moreutils:16:5: error: 'samples' was not declared in this scope
  samples.add(abuf[i]);
  ^
exit status 1
'RunningMedian' was not declared in this scope

The code in moreutils.ino is:

// additional processing
#include "moreutils.h"

void doMedian( float abuf[], float runmed[], int medianlength) {  // 
needs work!

   RunningMedian samples = RunningMedian(medianlength);
   for (int i=0; i< FFT_SIZE/2; i++) {
     samples.add(abuf[i]);
     if (i>medianlength-1) {
   runmed[i-medianlength] = samples.getMedian();
   // don't put value until the circ buffer is filled
     }
   }

truncated: Recommendations on cloning a bootable main disk Now: grub and mounting said disk

2018-12-02 Thread Bruce Labitt


Hi Jerry,

I'm clearly seeing the merit of your approach by now.  Next time, I 
think I'll do it that way.


Since I'm so deep into this (spent way too much time already), I'd like 
to complete the process. I've learned about gparted (how to use it 
successfully) and now hopefully grub.  Found the ppa for grub-customizer 
and installed it.


I see that grub was set up to have 0 seconds delay, so that it was not 
possible to intervene.  So it seems that the menu should both be made 
visible and the timeout set to 10 or more seconds, at least for now.  
Does that make sense?


Grub customizer seems to be referring to the active disk (which is not 
the one I want to change).  How do I get it to refer to the other disk?  
I will be doing a physical disk change, and still am holding up hopes to 
not screw up the known good disk.


Actually, sdc (it's actually changed, but let's keep it consistent for 
the whole thread) isn't mounted, and it seems I'm having issues mounting 
it correctly.


From "man mount", I see that if the device isn't in fstab, one does 
"mount /dev/sdc1 ..."  (I'm not sure what goes in ... )
However what is the dir that is referred to, on the host machine or on 
sdc1?  If I want full access to sdc1, I would do


$ sudo mount -t ext4 /dev/sdc1 / (really sdb1 now, as seen below)

If I do this I get:

$ lsblk --fs
NAME   FSTYPE LABEL UUID MOUNTPOINT
sda
├─sda1 ext4 6fb59d06-ec00-44f4-abcc-0da0f018be93 /
├─sda2
└─sda5 swap 616eaa19-299e-479b-8dcf-dfc36593f63a [SWAP]
sdb
├─sdb1 ext4 6fb59d06-ec00-44f4-abcc-0da0f018be93 / <--- this is the disk 
I attempted to mount

├─sdb2
└─sdb5 swap 38689ed0-1d07-416d-bd53-8dfb22554b3f
sdc
└─sdc1 ntfs A2DA53E7DA53B5EF
sr0
sdc and sdb have swapped.

Sorry for my confusion, but this stuff isn't obvious to me.  I seem to 
be missing a couple of idea that tie this all together.


I cannot see the drive show up in Files.  All I see is sda (boot disk) 
and sdc (a data disk).


How do I mount this disk?  It seems like this is a necessary step, is it 
not?
If I can't mount it, then how can I modify grub on it?  Or for that 
matter do a new system install on it.


For now, I have not made any changes in grub commander, and I have 
unmounted sdb1.


Wow, this has been messy so far, and compounded by my lack of expertise 
in the area.

The way I prefer to do it is to install a fresh os onto the new drive

up triple boot.

Re: Recommendations on cloning a bootable main disk

2018-12-02 Thread Bruce Labitt

So after changing the boot order to boot from the new drive first, BIOS 
had to fall back to booting from the smaller (original) drive.  I had no 
warning or display, BIOS switched over "silently".


What is the best way of diagnosing this and proceeding?  I presume 
something needs to be done to grub on the new disk.


Since I had done a dd copy, wouldn't grub already be there?

The 1MiB at the end of the drive appears to be related to GPT. If you 
aren't using GPT, shouldn't be an issue. With a 1 TB drive, you don't 
need to use GPT, in any event, though you could choose to. I have 
also seen such fragments of unallocated space. which appear to have 
been created due to partition alignment issues. I have never needed 
to leave such space available. Your partitioning tool may leave such 
space available, again, due to alignment issues.

Thanks for the tips on gparted.
Do I need to allocate 1MiB at the end of the drive?  I'm reading

I have had issues, in a few instances, with GParted, when taking
multiple steps at once.
Rather than do all the steps at once, I would do one step at a
time.
Apply it and let it complete.
Then do the next step.
GParted often works fine with multiple steps, except when it
doesn't. :-)

Further, you don't actually need to move the swap partition,
just recreate it in its final position.
That would save time, but doesn't explain the error.

These are the steps I would use, if I was doing it:
1. Delete the swap partition (sdc5)
2. Delete the extended partition (sdc2)
3. Apply steps 1 & 2.
4. Resize the data partition (sdc1), leaving 30 GB unallocated
at the end.
5. Apply step 4.
6. Create an extended partition in that 30 GB unallocated space.
7. Create a 30 GB swap partition in that new extended partition.

Partitions were dragged and moved per the basic instructions.

Can you give me a hint what went wrong?  I'm kind of surprised that it 
failed, essentially in the first step, growing the extended partition 
after turning linux-swap off.


The problem might be that gparted still has a problem with leaving 1MiB 
at the end for the duplicate boot information.  I found a comment in 
2017 for gparted: http://gparted-forum.surf4.info/viewtopic.php?id=17646


And: https://bugzilla.gnome.org/show_bug.cgi?id=738144

Is there a practical work around to my reported error?

On some of the BIOSes, unless you have the USB drive connected, before

Also, depending on the USB flash drive model, it may appear:
1) as a removable device (aka a floppy drive),
2) a hard drive (appearing as second choice under hard disk drives;
     you would need to change the 1st drive to USB and the 2nd drive to
your current boot drive), or
3) as a CDROM drive.

Also, if you have a UEFI BIOS, you may need to switch it to Legacy,
instead of UEFI.

Lastly, if you have a UEFI BIOS, you need a UEFI compatible boot device.
In the case of Clonezilla, you need to download an AMD664 alternative
version (Ubuntu-based), rather than the default Debian-based. (We have
both the UEFI and Legacy versions of Clonezilla to try when we run into
such issues.)

And, rarely, I encounter computers that simply cannot boot USB flash
drives, but those tend to be much older ones.

I *will* have to fix the bios, or I won't be able to boot from USB.

I did visit the AMI website, but it wasn't obvious how or if I could

At the moment, I'm not feeling very confident.  This all seemed easy a

Re: Recommendations on cloning a bootable main disk

2018-12-01 Thread Bruce Labitt

Totally unexpected fly in the ointment.  Option in BIOS to boot to USB 
has disappeared. Arggghh!


American Megatrends BIOS Version 2.15.1226 ca. 2012

There were 4 boot options - now there is only 3, and no (apparent) 
option to get a 4th option back.  I took a picture of the screen, but I 
won't clutter up the list.


I *will* have to fix the bios, or I won't be able to boot from USB.

Temp fix - just to get on with life, is to create a boot DVD.  Not even 
sure where I keep the DVDs anymore...  Fortunately, my laptop has a DVD 
writer.



I did visit the AMI website, but it wasn't obvious how or if I could 
upgrade the BIOS.  I sent them a tech support request, on upgrade, and 
in particular about the disappearing option, maybe I will get an answer 
next week.


At the moment, I'm not feeling very confident.  This all seemed easy a 
day ago, now its gotten complicated...

In my case, I want any reference to cc to point to
/opt/compiler_cuda/gcc.  It turns out /opt/compiler_cuda/gcc will be a
symlink as well.  Eventually the cc reference will end up pointing to
gcc-4.9, since CUDA7.5 does not support gcc5.

Is it
1)  ln -s cc /opt/compiler_cuda/gcc  or
2)  ln -s /opt/compiler_cuda/gcc cc

Which one does what I want?  Seriously confused.

I suspect you don't quite want either of those, actually.

It sounds a little like you're expecting "ln -s" to create a shell
command-alias or something (you never said *what directory* you want
to contain the "cc" symlink, but that's important!). It just creates a file.
In order for that file to be recognised as a command, you need to put it
in one of the directories that the shell searches ($PATH).

IF you want to used a symlink to create a "cc" command, you probably want
either:

 ln -s /opt/compiler_cuda/gcc /usr/local/bin/cc

... or:

 ln -s /opt/compiler_cuda/gcc ~/bin/cc

... depending on whether you're doing this for a system-wide default
or just for yourself. But I'm surprised that you're trying to do it
this way at all.

I usually just do something more like:

 export CC=/opt/compiler_cuda/gcc

... and then let the makefiles pick up that environment-variable.
Even if your Makefile is using implicit rules, it'll still pick up
and use the ${CC} value from your environment.

Are you actually using a Makefile or something that actually,
*explicitly*, has "cc" hardcoded rather than using "${CC}"?

I'd expect that you don't actually want to make a CUDA compiler
the default compiler for *all software* you build,
which is probably what you'll do by naming it "cc"
and putting it into your search-path




Original link:  from 
http://askubuntu.com/questions/693145/installing-cuda-7-5-toolkit-on-ubuntu-15-10


/I wanna share my experience on installing CUDA 7.5 (in order to use 
with Theano) on Ubuntu 15.10. /


//

1.

   /I installed Ubuntu 15.10 and the video driver (352.41) from the
   "Additional Drivers" tab;/

2.

   /Installed few dependencies like //|nvidia-modprobe|//(fix
   permissions problems), and for the samples compiling
   //|freeglut3-dev libx11-dev libxmu-dev libxi-dev libglu1-mesa-dev|/

3.

   /And because it needs GCC 4.9: //|sudo apt-get install gcc-4.9
   g++-4.9|//, then made symlinks in //|/opt/compiler_cuda|//(created
   the folder with an arbitrary name of my choice) as follows://
   / /|$ ls -la /opt/compiler_cuda/|//
   / /|lrwxrwxrwx 1 root root 22 Nov 2 16:14 cc ->
   /opt/compiler_cuda/gcc|//
   / /|lrwxrwxrwx 1 root root 16 Nov 2 16:13 g++ -> /usr/bin/g++-4.9|//
   / /|lrwxrwxrwx 1 root root 16 Nov 2 16:12 gcc -> /usr/bin/gcc-4.9|//
   //Registered //|update-alternatives|//with://
   / /|sudo update-alternatives --install /usr/bin/gcc gcc
   /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5|//
   / /|sudo update-alternatives --install /usr/bin/gcc gcc
   /usr/bin/gcc-4.9 50 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9|//
   /

4.

   /Downloaded "runfile (local)" 15.04 version, from //CUDA 7.5
   Downloads <https://developer.nvidia.com/cuda-downloads>//; and
   installed with://
   / /|sudo sh cuda_7.5.18_linux.run --silent --toolkit --override|//

   / /|export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH|/

5.

   /Appended //|compiler-bindir = /opt/compiler_cuda|//in
   //|nvcc.profile|//, so nvcc can use it./


I'm trying to do step 3.  I have seen similar instructions in the past.  
I may have done something like this in the past, but, I am temporarily 
suffering from CRS.  I believe this will work, although as you have 
stated, it may not be optimal.  For Wily Ubuntu 15.10, the default gcc 
is 5.2.  Nvidia is stuck at 4.9, hence the update alternatives command 
in step 3.


Is there any reason step 3) won't work?

To make the symlink |cc -> /opt/compiler_cuda/gcc, what is the command?

Does *ln -s  /usr/bin/cc /opt/compiler_cuda/gcc*  do what the author 
states above?  Or do I have it backwards?  Let's just say this is a 
dyslexic moment. Please confirm if this makes sense, or I should be 
doing something else.


As far as I know, nvcc has the smarts to use nvcc to compile cuda code, 
and gcc/g++ for everything else.


Best regards
-Bruce

It's helps to remember, too, the reason for the order is that the 
second option isn't required. It will put a symlink with the same base 
name in your current working directory without it.

Re: Need some suggestions on a borked upgrade

2015-05-10 Thread Bruce Labitt

Ok.  Seemed to have lost the ability to log into x.

I can login.  I ran the command and it created the log file.  How do you mount 
a usb stick when you don't know its name?  Then I can copy the file.

It's getting to the point of removing the drive, copying /home and doing a new 
installation.

Need some suggestions on a borked upgrade

2015-05-10 Thread Bruce Labitt

Been quiet on the list.

Upgrade from Ubuntu 14.10 to 15.04.  Apt seems to be hung up with 
removing a single file - which is old and not needed.  But because of 
this the upgrade is severely screwed up.  Not sure if it will boot again 
properly.  I just downloaded an 15.04 iso to burn to a usbstick to act 
as a rescue if needed.

Package is octave3.2-info, for some reason it has dependencies on perl.  
Perl is apparently used by a lot of packages in some way, and all of 
these necessary packages are "half installed".  It got so bad that 
dist-upgrade hung because there were too many errors.

There is some sort of directory issue, which generates an error message 
if I attempt to apt-get remove octave3.2-info.
I think, if I can remove or delete this file (and remove references to 
it) perhaps the rest of the install will go through.  This, of course 
sound 'dangerous' but I have run out of ideas.

Any suggestions?  apt-get -f install returns the error message. apt-get 
remove returns the same error.  Looking for a few ideas. I'll try to use 
some of them tonight to attempt a fix.  Got to visit Mom now...

Regards,
Bruce

Re: Can this disk be repaired? Does it need to be?

2014-12-04 Thread Bruce Labitt

Yes, I'll get another disk to check this one😡. I just bought this SSD a few 
weeks ago.

Can FAT32 support "weird" aka Linux file names?  If not, which is most likely 
true, I'll have to pull the blade server nfs "image" off this disk.  I have 
directories with MAC ID's as directory names.  I'm sure that is messing up 
windows.

At this time I can't dump Win7 as that is my work issued machine.  Later, I'd 
like to change that...  One battle at a time...

Re: Can this disk be repaired? Does it need to be?

2014-12-04 Thread Bruce Labitt

It is kind of funny, I just bought this disk because another one WD Passport 
was starting to fail/get flakey.  The right thing to do is to get another disk.

This SSD was to be my carry around disk containing work I've done in the past 
as reference.  My brains so to speak.  Pity in windows it (the disk) has lost 
its mind.  Linux/Ubuntu has no problems with the disk, so far.

I guess a NAS is in my future.

Thanks for your suggestions.
