MacOS

I’ve been having an odd issue for a couple of months. When accessing sites having a .dev domain (like most recently go.dev), I my browsers have given me warnings and as many had HSTS-headers, not allowed me to visit the site.

It seemed like a strange error, and I’ve tried to remember if I’ve set up some proxy or VPN connection, that could cause this issue. A few times I’ve asked others on the net if they had issues - which was not the case - and I’ve tried using a web proxy, and everything worked. Yet no matter which browser I used it didn’t work.

Building audiobooks on (Debian) Linux in the m4b format is actually possible and doesn’t have to be a pain. I’ve found numerous recipes with shell instructions, but having a nice simple app to handle the building of the books seems much easier.

Most of the apps available for Linux seemed to be in a pre-alpha state, but after a few experiments I’ve settled on m4baker, which - while a bit rough - actually seems to do the job just fine.

Running a modern IT platform is rarely an easy nor isolated task. Most platforms consist of a fairly large number of components ranging from OS level to 3. party libraries and components added in the user interfacing layers - and adding numerous integrations does make it an interesting challenge to quickly identify and correct bugs and errors.

While the system complexity does pose a challenge is surely not an impossible task, as several tools exists for most - if not all - platforms to allow instrumentation of the platform and utilize the instrumentation tools to handle the platform and identify issues quickly.

While it really isn’t secure at any measure, ftp is a very useful way of moving files around. Apple’s OSX have a build-in basic ftp server, but in Lion (version 10.7) the user interface seems to have disappeared from the User interface. The servers is still available under the hood if you need it.

To enable the ftp-server (the availability) enter this command in a terminal window:

sudo launchctl load -w /System/Library/LaunchDaemons/ftp.plist

Suppose you got an important mail, but by accident deleted the message – and to make matters worse, you also decided that emptying the mailbox was a pretty neat idea. Is then time to Panic?

Well it might, but there is a chance you might be able to undelete the message – and quite easily if you’re on a Mac or a Linux machine. Here are the few steps, which has helped recover a lost mail or two… First close Thunderbird. Then located the mail directory (on Linux it’s located in the subdirectory .mozilla-thunderbird in you home directory – on windows most likely somewhere in C:\Documents and Settings*\Application Data\Thunderbird – In there you’re looking for the “Local Folders” directory.
