I had a rather large Akeeba Backup file (about 25 GB) which I tried to restore using Akeeba kickstart from the web browser. It took a long time unpacking the archive but never reached the point where database is being restored.
The Akeeba kickstart (version 5.0 or later) can be run from command line (shell) and this works better with really large backup files. Simply go to the directory where you have your JPA-file which should be the same directory where it should be restored and enter:
php kickstart.php archive.jpa
But of course replace archive.jpa whith your archive name. There are more command line options available.
After unpacking the archive, go with your browser to https://yourdomain.com/installation and complete the restore.

The antenna seems always to be a compromise between practical matters and performance. While not being the most high performance antenna, I find the end fed half wave (EFHW) a very practical antenna, especially during portable operations.
The EFHW doesn’t need to be straight. It can be bent in angles and be “abused” a lot.
In this video I have a temporary installation in a vacation home (time share) where I am not able to erect any masts, not being able to use trees or other houses as fixation points for my antenna. I used some zip ties only that can be removed without leaving any marks.
The antenna height is far from optimal and the antenna is bent several times. It is also close to the rain gutters made of metal. Still I have fine SWR levels on all bands (10/15/20/40 m) and can work all of Europe on my QRP rig (6 watts) (see the screenshot from Reverse Beacon Network).

This is kind of a special scenario but actually occured for me. A port on the pfSense WAN should be NAT:ed to an IP-address located on a remote subnet via an ipsec tunnel. The problem here was the router on the other end of the tunnel did not route all it’s outgoing traffic over the tunnel. Only a few subnets behind the pfSense went through the tunnel. All other traffic was using the routers normal Internet connection.
In the image above, a port (123 in the example code below) on the pfSense (18.104.22.168) should be NAT:ed and port forwarded to 10.0.0.7. The result was the NAT:ed port forwarded packets reached the intended host (10.0.0.7) but replies probably went straight back on the internet, not going back through the tunnel.
I solved this by setting up a simple proxy on a server using iptables located on a machine in one of the subnets at the pfSense site which was reachable from 10.0.0.7 through the tunnel. See next image.
The proxy was made using iptables in a Ubuntu machine on 10.2.2.2. Both the proxy server on 10.2.2.2 and the host 10.0.0.7 could reach each other over the ipsec tunnel.
In pfSense I changed the NAT / port forward of port 123 from 10.0.0.7 to 10.2.2.2 (and deleted the existing states in pfsense from my previous tries, until I did that, this didn’t work).
You will probably want to make sysctl ip_forward and iptables statements persistent over reboots.

To workaround this problem, manually edit the file /usr/local/ispconfig/interface/web/monitor/lib/lang/XX.lng (where XX is your language). Find the line beginning with:
$wb['Let's Encrypt log'] =
Insert a backslash like this:
$wb['Let\'s Encrypt log'] =
Save the file and your Monitor tab will work again. This must be repeated each time you edit the translations for monitor.

In a house in Denmark I needed to clean the water trap in a floor drain looking like the one in the photo. (For some weird reason, these kind of household tasks always end up on the male… But that is another discussion :).)
I wrongly made the assumption that I needed to unscrew the four screws. Bad decision! This made the upper and lower part of the water lock to separate and the lower part fell into to the waste water pipe. Fortunately there was a bend some 30 centimeters down so it stuck there and I only (!) hade to put my arm into the pipe, grab it and pull it out.
To get the water trap out was actually more simple than anticipated. This how it should have been done: just put your gloves on, stick two fingers in the big hole and a thumb at the edge and pull. When removed and safely away from the waste water pipe, the four screws can be unscrewed in order to separate the two parts of the water lock so it can be cleaned more easily.

I wanted to make a “stealth installation” of my Anytone AT-D578UV radio in my Toyota Prius (2008) so I don’t have to worry so much for burglars when parking the car. Below the FM-radio is a compartment, when removed, leaves a space big enough for the radio.
There is plenty of space behind the compartment. I was a bit worried about that issue becase the radio is longer than the depth of the compartment, but it turned out there is enough empty space behind it.
I installed the radio with the programming cable connected as it will be very hard to connect it after the radio is mounted in the car. The microphone is extended and connected using a flat straight ethernet cable and both cables are dropped downwards and pulled out from behind the panel. That way I can easily hide the microphone when parking the car.
When the compartment under the radio is removed (and saved to be reinstalled when selling the car), the space between the metal plates is to wide, so I took a 5 mm nylon cutting bord that I cut into pieces and glued them together to form a suitable spacer and drilled a hole for the mounting screw. I did not use the mounting screws that came with the radio, instead I used one M4x20 mm and one M4x40 mm. On the right side of the radio I used 2 nylon pieces and on the left side 5 or 6. The screws went into the rear holes on the radio and to get some support for the front I used zip tie straps around the radio through the holes in the metal plates.
The GPS was just tucked up behind the navitor screen, just to the right of the speaker. A note about the GPS antenna connector. After about 6 months after installation, I had no GPS signal on the Anytone AT-D587UV. It turned out that the SMA-connector, that I tightened by hand, hade shaken loose by the vibrations. So do tight it a bit with a small wrench, not overtightening it but enough to keep it from getting loose.
For power, I routed two 6 mm2 wires directly from the battery (with a 30A fuse close to the battery) and routed them through the left trunk panel and inside the side panels below the doors to the front. The antenna cable went the same way and I didn’t want to drill a hole in the car so I used a trunk lid mount even though the performance for those are often not as good.
These are some useful tutorial videos as you need to uninstall and reinstall the stereo in order to install the Anytone AT-D578UV below it.

With the number of assigned DMR ID:s on radioid.net going over 200.000 we are over the limit of the capacity for the Contact List on the older Anytone models. Anytone:s under estimation in design is not the first in history. Remember Bill Gates saying that no-one, ever, is going to need more than 640 kB RAM?
So we need to select which regions of DMR ID:s to incluide in our contact lists in our Anytone radios.
In addition to that it is a good idea to enable Talker Alias to sort of increase the chance of just not seeing a DMR ID in the display. Not all repeaters supports it though.
Make sure your own Radio ID Name is set in the form “CALLSIGN Name” (your callsign and first name separated with a space). Set your radio on a DMR channel, then MENU -> Settings -> Chan Set -> Radio ID -> select your ID -> Option -> Edit Name -> Confirm
MENU -> Talk Group -> Talker Alias -> Alias Tx Set -> On
MENU -> Talk Group -> Talker Alias -> Alias Rx Dis -> Contact First

The problem was that module class suffix was not working and the first solution was to make a tpl file override, placed in local/tpls/blocks and change style=”raw” to style=”xhtml” for the module in question. This solution had been working for years, but suddenly the client reported that their site was “looking weird” again.
It turned out the module class suffix had stopped working again.
The solution this time was quite simple. The site had been updated and the T3 system plugin was version 3.0.2. By updating it to 3.0.4 the problem was solved.

Microsoft is phasing out Internet Explorer and moves over to Edge. In order to facilitate that, some users experience that when they click on the Internet Explorer, it actually opens up Edge. In rare situations, the user might need Internet Explorer instead of Edge.
Find the settings for “Let Internet Explorer open sites in Microsoft Edge” and set it to Never
Click on the Internet Explorer icon. Now MSIE should open.

After an upgrade of WordPress, the site reported “There has been a critical error on your website. Learn more about debugging in WordPress.”. When investigating the web server log files, errors reporting “Call to undefined function the_field()”.
Solution: During the upgrade process, the plugin “Advanced Custom Fields” had been disabled. By activating the plugin, the problem was solved.
