Google Chrome URL chrome://devices/ -> your registered Google Cloud devices like printers

Posted by jpluimers on 2021/01/18

Just learned a new Google Chrome URL chrome://devices/ which lists your Google Cloud devices like printers.

Though in the case of OKI printers, you have to enter your printers at the printer which the Menu button is a painful exercise. [WayBack] oki-c332dn-control-panel_maxwidth.jpg (525×550).

You can also view the device list in https://www.google.com/cloudprint#printers

For some OKI printers (including the MC342 series) you need to update the firmware. For a Mac, you need the below firmware update tool that automagically:

  1. detects the printers
  2. finds the firmware on the internet
  3. updates the printer

Tool: [WayBack] FWUP_020000_10.7.dmg via [WayBack] Firmware Update | OKI Global

The messenger – Delta Chat – Email Based Instant Messenger; based on IMAP push

Posted by jpluimers on 2021/01/18

[WayBack] The messenger – Delta Chat: Delta Chat – Email Based Instant Messenger

From the FAQ at [WayBack] Help – Delta Chat:

What are the advantages of Delta Chat compared to other messengers?

  • Independent of any company or services. You own your data.
  • Your data are not saved on a central server; this way, in contrast to most other messengers, Delta Chat even protects your metadata (who writes to whom?)
  • You do not distribute your address book to anyone.
  • Fast by the use of Push-IMAP
  • Largest userbase – receivers not using Delta Chat can be reached as well
  • Compatible – not only to itself
  • Elegant and simple user interface
  • Distributed system
  • No Spam – only messages of known users are shown by default
  • Reliable – safe for professional use
  • Trustworthy – can even be used for business messages
  • fully Open Source and Standards based

What if the receiver does not use Delta Chat?

  • The receiver will get a normal email then – if he replies to it, you will see the reply in the Delta Chat app.

TUMBLEWEED Ordering cycle at boot with nss-lookup: named fails to start initially; workaround: manually `rcnamed start`

Posted by jpluimers on 2021/01/15

I have seen this on one Raspberry Pi 3 system: named failing to start during a normal reboot.

The solution is to manually rcnamed start as root after boot.

From [Wayback] TUMBLEWEED Ordering cycle at boot with nss-lookup, the rcnamed status is the same as on my system, but no solution in that thread:

# systemctl status named
● named.service - Berkeley Internet Name Domain (DNS)
     Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled)
     Active: inactive (dead) Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found ordering cycle on named.service/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found dependency on time-sync.target/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found dependency on ntpd.service/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Found dependency on nss-lookup.target/start
Jul 02 08:13:40 hpprol2 systemd[1]: nss-lookup.target: Job named.service/start deleted to break ordering cycle starting with nss-lookup.target/start

Apparently, sometimes there is a service startup dependency loop, and named becomes the victim of it, effectively rendering DNS inoperable.

My system was running this version of Tumbleweed:

statler:~ # cat /etc/SUSE-brand /etc/os-release 
openSUSE
VERSION = tumbleweed
NAME="openSUSE Tumbleweed"
# VERSION="20200825"
ID="opensuse-tumbleweed"
ID_LIKE="opensuse suse"
VERSION_ID="20200825"
PRETTY_NAME="openSUSE Tumbleweed"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:tumbleweed:20200825"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"
LOGO="distributor-logo"

On an identical system, the boot just worked fine, so it might be timing related.

waldorf:~ # cat /etc/SUSE-brand /etc/os-release 
openSUSE
VERSION = tumbleweed
NAME="openSUSE Tumbleweed"
# VERSION="20200825"
ID="opensuse-tumbleweed"
ID_LIKE="opensuse suse"
VERSION_ID="20200825"
PRETTY_NAME="openSUSE Tumbleweed"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:tumbleweed:20200825"
BUG_REPORT_URL="https://bugs.opensuse.org"
HOME_URL="https://www.opensuse.org/"
LOGO="distributor-logo"

It has been fixed late January 2021 as per [Wayback] Bug 1177491 – systemd ordering cycle with nss-lookup.target:

Josef Möllers 2021-01-27 15:50:15 UTC
Fixed by removing "Before=nss-lookup.target" from systemd's service file.

It means editing /etc/systemd/system/multi-user.target.wants/named.service from

[Unit]
Description=Berkeley Internet Name Domain (DNS)
After=network.target
After=time-sync.target
Before=nss-lookup.target
Wants=nss-lookup.target
Wants=time-sync.target

[Service]
Type=forking
ExecStart=/usr/sbin/named.init start
ExecReload=/usr/sbin/named.init reload
ExecStop=/usr/sbin/named.init stop

[Install]
WantedBy=multi-user.target

into

[Unit]
Description=Berkeley Internet Name Domain (DNS)
After=network.target
After=time-sync.target
Wants=nss-lookup.target
Wants=time-sync.target

[Service]
Type=forking
ExecStart=/usr/sbin/named.init start
ExecReload=/usr/sbin/named.init reload
ExecStop=/usr/sbin/named.init stop

[Install]
WantedBy=multi-user.target

Note that it is an alias, so it won’t show up in a versioned /etc directory (for instance using etckeeper):

# ls -Alh /etc/systemd/system/multi-user.target.wants/named.service 
lrwxrwxrwx 1 root root 37 Sep  5  2020 /etc/systemd/system/multi-user.target.wants/named.service -> /usr/lib/systemd/system/named.service

Having the Tom Bihn Brain Bag as day-to-day backpack, I wonder about the PeakDesign Travel Backpack

Posted by jpluimers on 2021/01/15

Having the Tom Bihn Brain Bag as day-to-day backpack, I wonder about the PeakDesign Travel Backpack.

The features I like most about the [WayBack] Tom Bihn Brain Bag are:

  • that it has 2 big main compartments,
  • the rail system allowing easy attached removal of one or two laptop caches [WayBack],
  • the freudian slip insert [WayBack],
  • the snake charmer accessory [WayBack],
  • the materials last forever
    (my first lasted 20+ years, so I gave it to mentally retarded brother. To bad he disposed it, not realising how durable it was “it was too big for my work-stuffand too small for my diving flippers, so I threw it away”)

Two more things I like, but are not available any more (new products are being designed for them):

I wonder about the material differences between the two too backpacks.

Here are some links if you want to compare them yourself:

The difference between thread-safety and re-entrancy – The Old New Thing

Posted by jpluimers on 2021/01/13

Just in case I need a nice example about the difference: [WayBack] The difference between thread-safety and re-entrancy – The Old New Thing.

It has both that and the definition:

An operation is “thread-safe” if it can be performed from multiple threads safely, even if the calls happen simultaneously on multiple threads.

An operation is re-entrant if it can be performed while the operation is already in progress (perhaps in another context). This is a stronger concept than thread-safety, because the second attempt to perform the operation can even come from within the same thread.

Programming Wisdom auf Twitter: ““Good code is its own best documentation. As you’re about to add a comment, ask yourself, “How can I improve the code so that this comment isn’t needed?” Improve the code and then document it to make it even clearer.” – Steve McConnell”

[WayBack] Programming Wisdom auf Twitter: ““Good code is its own best documentation. As you’re about to add a comment, ask yourself, “How can I improve the code so that this comment isn’t needed?” Improve the code and then document it to make it even clearer.” – Steve McConnell”

Code the why in a clean and understandable way.

Then document the how, and clear up any implementation/usage details that are hard to understand.
