First Post of curiosity
Australia Post and SMS scam - how do they (scammers) know so much?
I wonder if someone has dug to the bottom of this, so today I had this situation again - where it was very clear that there is some data leak, somewhere 🤔
So there is indeed a parcel coming in today from reputable seller (Adidas - yes yes I do need those new running shoes!), and almost EXACTLY at the estimated time of the delivery - I got this SMS message (see the screenshot).
I have not ordered anything for quite a while now, and didn't receive anything like that for all that time, so this is definitely NOT a coincidence - they knew when to send it, and where to.
How do they know - is there an unrestricted API endpoint somewhere where scammers can simply iterate on the tracking ID, and get all the details about me ?
There were couple threads about this already, so this has been happening for a while - https://www.reddit.com/r/australian/comments/15gnw65/australia_post_leaks_my_mobile_number_change_my/
Anyone else seen this before?

I've taken the time to read this IT notes Story where we are reminded to use Open Source Code in the diverse way it's intended
I can give you an example regarding the _if tools_
**ifconfig** is in my _muscle memory_ the things that I need executed from this program just fly out of my fingers in reflex mode
I've been using the if tools ever since we needed to _compile everything_ ourselves, when we wanted to run an Open Source Environment, where the kernel was written and delivered in source code only.
If this is the first toot you read by me, I've been with the Open Source community on the Linux side since the alpha versions were coded and distributed through Usenet, in comp.os.unix.*
In that period you were grateful when a task set that you needed to execute, had a program, which would either make your task easier or better manageable, than doing everything by hand in a laborious manner
Ever since the beginning there are different GNU programs, written in the Richard Stallman period, that can do similar things. All you need to do is choose what you like and stick with it
If you do not like the way it works, you can fork it & change the code, if you don't know how to write a line of code, there are _manual pages_ available which you can use as teaching methods to learn how to code yourself
All you need to be for that is an _autodidact_
You have the power of the **Source Code** readily available right in front of you
At a certain point in time _Bram Molenaar_ did not like the way VI worked; he want it more than vi offered. At this point in time Bram Molenaar programmed vim on the _Amiga_ computer. Since the true Open Source form was followed vim was also distributed in Source form and was happily adopted by others who were thinking in a similar manner as Bram Molenaar and they started to contribute to that program.
vi is a vital program on UNIX systems. What Bram has made, is create a _choice_ for people who want it more than what vi offered.
# vim & vi happily coexist!
## This is the beauty of Open Source
At a later point in time this is also what happened with the programmer who wanted more than what the if-tool set offers. Thus the command set of _ip_ was programmed. Similar to vi and vim they happily coexist.
### However on the distribution level something changed.
After a couple of decades I noticed that traditional tools, that have been tried, tested, stable and have withstood the test of time, were dropped from the base installations. You have to go and fetch them yourself. It was even done with _critical tools_ like the if tool set. It's not just one distribution that's doing it but different distributions.
I was busy with an installation; at a certain point I needed **ifconfig** to work on my network interface devices; I needed to configure something on the fly. Imagine my facial expression when I detected that ifconfig wasn't in the base installation!
The machine was in a _chicken egg_ situation because I had &no access to the network_ I had to stop, go to another place fetch the if tools separately, find out that they were dropped for reasons which were totally irrelevant to my work, go back to the machine, install them separately and in the process waste many valuable minutes of time.
It was then that I started to notice the pattern a pattern of **polarization** removing tools which are critical to base installations without leaving a warning
I had to _change_ my setup routine which has been working for decades in a _flawless_ manner, because someone somewhere decided that a good tool set became obsolete.
This polarization is not only in the choice of what commands are chosen to be in the base installation of a distribution, it's in many different sections of the open source community which is what Stefano has shed some light upon.
Polarization because of diversity is totally unnecessary, happy and peaceful coexistance is key
* You can love vim yet cherish vi
* You can glorify emacs yet admire vim
* I can love XCFE cherish LXDE, admire KDE & like GNOME all simultaneously
Depending up on what I'm doing, what machine I am working on (SBC server embedded system), what is needed on the task at hand, I simply adapt and work with the diverse tools available for free.
There is absolutely now need for polarisation or Toxic behavior in the Open Source ENV:
Another example is the direction that Gnome went many years ago.
In that period I used Enlightenment, Gnome, KDE and FVWM simultaneously on different machines. All WM are working in a manner that I like. When however the Gnome programmers decided to strip configuration features of the Desktop Environment, I didn't go on a rant, I didn't bother to fork, because of the massive amount of work involved.
I just left in Peace
Diversity is Vital. GNOME is Vital! We need them all

The dining table today, because it is World Postcard Day! I send a few Postcrossing cards to India, the USA, Russia and Germany and cards to friends and my niece. But the day isn't over yet! So I will write a few more and post them tomorrow...
Also, I recently found out that you can follow Postcrossing in the Fediverse!: @postcrossing@mastodon.social

A white hand holding up a hand of postcards outside in a garden. There is yellow Miffy card, an illustration of a starry night, a famous painting of a cliff by Monet and a painting of ducks, a heron and other birds in a shallow river. The other cards are mostly hidden behind the others.
A table full of postcards with a cup of tea in the middle. The postcards are all very different. Some show paintings or illustrations, photos of old manuscripts, mushrooms and a black photo of a beach.

Yet to find an article on our white paper for NASA on the work needed to anticipate the challenges and societal impacts of a possible discovery of life beyond earth that doesn’t lead with: “aliens!!!”
But, I guess that’s part of the course…
It was extremely interesting to author this paper with such a varied group of researchers at the @setihub. An honour and a pleasure to work with such curious and generous colleagues.

@campuscodi it was a total mess. There is no justification for the emergency service phone number going down. Also #Post should have refrained from inititally saying it was not a cyber attack until they knew what was going on. That said #Post did an excellemt job on getting everything back up.
