I am long-time subscriber to a service that is delivering a curated choice of scientific papers to your inbox every morning.
And even better: On top of the choice and link of the paper you also get a great summary with additional links and hints on the topic.
The Morning Paper: a short summary every weekday of an important, influential, topical or otherwise interesting paper in the field of computer science.https://blog.acolyer.org/about/
Depending on your specific interests the papers chosen will give you deep insights into certain topics. Recently a lot of AI related topics show up there.
Living in an UNESCO world heritage city has a lot of advantages. One of them is the amount of nice parks and areas to enjoy the spring sun.
We’ve spent the afternoon walking around and taking some pictures.
allow me to explain by quoting wikipedia:
Dicordianism is a paradigm based upon the book Principia Discordia, written by Greg Hill with Kerry Wendell Thornley in 1963, the two working under the pseudonyms Malaclypse the Younger and Omar Khayyam Ravenhurst.
According to its primary historian, Adam Gorightly, Discordianism was founded as a parody religion. Many outside observers still regard Discordianism as a parody religion, although some of its adherents may utilize it as a legitimate religion or as a metaphor for a governing philosophy.
The Principia Discordia, if read literally, encourages the worship of Eris, known in Latin as Discordia, the goddess of disorder, or archetypes and ideals associated with her. Depending on the version of Discordianism, Eris might be considered the goddess exclusively of disorder or the goddess of disorder and chaos.
Both views are supported by the Principia Discordia. The Principia Discordia holds three core principles: the Aneristic (order), the Eristic (disorder), and the notion that both are mere illusions.
Due to these principles, a Discordian believes there is no distinction between disorder and chaos, since the only difference between the two is that one refers to ‘order’.
This is likely a major reason for the inconsistency in the wording. An argument presented by the text is that it is only by rejecting these principles that you can truly perceive reality as it is, chaos.wikipedia
And given that information you can expect a discordian calendar to exist. This calendar defines years (YOLD = year of our lady of discord) and seasons and days. And holydays:
Very little is known about this holyday. What we do know is pretty much made up as we go along.discordia wikia GFDL
So now back to the holyday itself. How would you celebrate such a distinguished day?
It is a simple one step process: shove unasked advertising in my face. Bonus points for loud full blast audio right of the start.
If I ever see unasked advertising that tried to be sneaky or not do sneaky I am going to block it without noticing from whom or for what it was.
But when it’s shown so often and is so intrusive that I take note of your brand. That brand is not considered for future business anymore.
That is especially for services where I am the product paying with my data.
With the release of the full album this week it’s the the first full album by them for over 15 years. And to me delight their sound is back to well known heights!
We use the term “smart home” lightly these days. It has become a term of marketing and phantastic stories.
Considering how readily available lots of different sensors, actors and personal-assistants are these days one would think that most people would start to expect more from the marketing “smart-home”.
I believe that the smart is to be found in the small and simple. There are a lot of small things that actually make something feel smart without it actually being smart about anything.
Being smart is something not achieved yet – not even by a far stretch of the sense of the word. So let’s put that to the sides of the discussion for now and move a simple thing in the middle of this article.
Have you ever had an argument about who should or should have cleared out the dishwasher after it’s finished?
So we outsourced the discussion and decision to a 3rd party. We made our house understand when the dishwasher starts and ends it’s task. And made it flip a coin.
There was already a power consumption monitoring in place for the dishwasher. Adding a hysteresis over that monitoring would yield a simple “starts running” / “stops running” state of the dishwasher.
Pictured above is said power consumption.
Now adding a bit of random coin-tossing by the computer and each time when the dishwasher is detected to have started work a message is sent out depending on the result of the coin-toss.
That message is published and automatically displayed on all active displays in the house (TVs/…) and sent as push notifications to all members that need to be informed of this conclusive and important decision.
Everyone gets a push notification who is going to clear out the dishwasher based upon a coin-toss by a computer every time the dishwasher starts.
The base of all of this is a Node-RED flow that that uses the power consumption MQTT messages as an input and outputs back to MQTT as well as pushes out the push notifications to phones, screens and watches.
Additionally it creates a calendar entry with the start-finish time of the dishwasher run as well as the total energy consumption for this run.
The flow works like this: on the right the message enters the flow from MQTT. The message itself contains just the value of the power consumed at this very moment. In this case consumed the dishwasher.
The power consumption is updated regularly, every couple of seconds this way. So every couple of seconds this flow runs and gets an updated value of
Next a hysteresis is applied. In simple terms this means: when the value goes above a certain threshold the dishwasher is considered to be running. When it goes below a certain threshold then it is considered finished.
When the dishwasher changed it’s state to “running” the flow will generate a random number between 0 and 1. This give a 50:50 chance for either Steffi or Daniel be the chosen one to clear out the dishwasher for this run. This message is sent out as push notification to all phones, watches and TVs.
When the dishwasher finishes it’s run the total energy consumption is taken and sent out as the “I am done message”. Also this information is added to the calendar. Voilá.
A calendar? Why a calendar you may ask. Oh well there are several reasons. Think of calendars as another way to interact with the house. All sorts of things happen on a timeline. A calendar is only a visual aid to interact with timelines.
May it be a home appliance running and motion being sensed for your home alarm system. All of that can be displayed in a calendar and thus automatically sync to all your devices capable to display this calendar.
And if you start adding entries to a calendar that the house uses to know what to do next… how about putting light on-off times into an actual calendar right on your phone instead of a complicated browser user interface like many of those marketing smart-homes want us to use?

Apple has started to force developers that want to develop and publish on the MacOS and iOS platform to enable two-factor authentication.
Two-factor authentication (also known as 2FA) is a type, or subset, of multi-factor authentication. It is a method of confirming users’ claimed identities by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are.wikipedia
When I just got around enabling it for one of the apple accounts I’ve got there seems to be a much much higher security barrier in place already…
That’s probably some sort of zero-factor no-authentication. I guess. Anyway: Kudos to Apple for finally forcing people to minimum standards. Properly integrating the second factor will make this so much simpler for users. Apples ecosystem solution already is quite well integrated.
Have you switched all your daily used services to two-factor authentication yet?
Apparently yesterday somebody pushed the wrong button. Twice.
Like most countries Germany got a system in place to broadcast out warnings to the public in case of disasters or else.
And it proved to be quite useful in the past when it comes to the occasional storm or heavy snowfall/rain/lightning.
Seeing that they run a test and then again send out an apology to have run a test is puzzling and funny at the same time. Everyone has a “bad hair” day, right?
