Try this:

FrontDoor is being resurrected…

Posted by jpluimers on 2017/08/29

After 3 years silence, JoHo has managed to resurrect the DOS version of FrontDoor and blogs about it at [A] reboot . defsol . com | Waiting for a call or event.

Found out via [WayBack] So, after having been asleep for some 15 years, it appears this is actually happening #frontdoor #fidonet <ht… – Joaquim Homrighausen – Google+

So I had a private chat with JoHo, where he wrote me this:

After three years of “silence”, and some 15+ years since the last code update, JoHo has appeared on the FidoNet scene once again. Having relased FrontDoor in 1986, I guess it’s safe to say he’s been around (FidoNet) longer than most people.

The biggest issue(s) seem to have been finding all the bits and pieces required to make/update FrontDoor, its utilities, as well as the long dead license key/code generator. Another issue is, of course, to find a suitable operating environment to put the pieces together in.

JoHo has stated that what used to be called the “Commercial/MultiLine” version of FrontDoor is what every future of version will be, except not so “Commercial”. You can get a free license by simply sending him an e-mail. Look at https://www.defsol.com for more details.

The “Reboot” project, as JoHo calls it, will have some details released at https://reboot.defsol.com. There is also a Facebook group available for FrontDoor users.

When asked “Why are you doing this now?”, JoHo responds with “Have you ever seen ‘Finnish Swamp Wrestling’ on YouTube? There is no ‘Why’, there is only ‘Because’.”

JoHo can be reached at defsol@defsol.se, seen on Twitter at @joho68. He has also applied for a new FTN-address in Zone 2. Details will follow.

Here are some more links and pictures:

Good old FidoNet logo:

Mikrotik date and time calculations

Posted by jpluimers on 2017/08/29

Some ideas for date and time calculation:

It should get better (and verifyable) implementations in stead of these Julian (not Gregorian!) date conversions:

regex – Regular expression to match DNS hostname or IP Address? – Stack Overflow

Posted by jpluimers on 2017/08/29

I’m not fond of them, but sometimes they can do their job regex – Regular expression to match DNS hostname or IP Address? – Stack Overflow

Two notes:

  1. The first answer matches either IPv4 or hostname
    (no IPv6 support yet; reminder to self: find it one day).
  2. The second answer restricts the hostname parts to be no more than 63 characters each. It doesn’t fix the total length being 255 or less
    (reminder to self: create that restriction one day).

First answer:

systemd/udev: PredictableNetworkInterfaceNames

Posted by jpluimers on 2017/08/28

This is so cool, but will take some time for lot’s of tooling to become compatible:

Starting with v197 systemd/udev will automatically assign predictable, stable network interface names for all local Ethernet, WLAN and WWAN interfaces. This is a departure from the traditional interface naming scheme (“eth0”, “eth1”, “wlan0”, …), but should fix real problems.

exporting firewall config – MikroTik RouterOS

Posted by jpluimers on 2017/08/28

Example:

/ip firewall filter export file=ip-firewall-filter.rsc

This exports the Filters parts of the IP Firewall into a file named ip-firewall-filter.rsc in the user-space root of the Mikrotik router file system that you can access through the Files menu entry in WinBox or by external access through FTP or SFTP (SSH File Transfer Protocol).

Running your Mac Mini headless by faking a display for it (HDMI 1080p/4K or Thunderbolt VGA); similar for DVI

Posted by jpluimers on 2017/08/28

CompuLab 4K Display Emulator (fit-Headless 4K)

CompuLab 4K Display Emulator (fit-Headless 4K)

The MacMini is a bit dumb as it won’t enable the GPU when there is no display attached. Which means headless operation is cumbersome as display rendering is very slow.

There are a few tricks of which the off-the-shelve HDMI solutions work best.

You can buy them at Amazon:

CompuLab Display Emulator (fit-Headless)

Basically the trick to simulate a monitor with a dummy load works for other display connectors as well (most of them work fine with 75 ohm resistors, usually a bit lower or higher works just as well):

Performance Test WCF/WPF app – Selecting right Tool

Posted by jpluimers on 2017/08/26

Interesting read, especially because they did an extensive tool selection process. Not really up to date any more but a good start when you are looking for tools.

Amsterdam, 2.4 GHz. 5 GHz is only marginally better. In the city, wired connection is the only option: fiber, cable, dsl.

Posted by jpluimers on 2017/08/25

For me, too often – even at home – mobile internet is faster than WiFi over 2.4 Ghz and sometimes even faster than WiFi at 5 Ghz..

Further below is inside my home. I’ve no idea what these – relatively strong – networks are:

  • SANDS Wi-Fi Network (it has a MAC in the OUI list of Apple and is configured as GB device)
  • venus-HQ17128EGKE-5ae (it has a MAC in the local private range)
  • H368N8D6382 (and a network HZN242961585 that looks similar but is very different – the first has a MAC from ZTE corporation, the last from Samsung Electronics)
