Frage zum musikalischen Urheberrecht

Angenommen, ich nehme all den Klassikvorrat, der nicht unter das Urheberrecht fällt her (z.B. Kirchentonarten, alle Klassiker vor 1900 der Moderne, wie Bach, Mozart, ...) und nehme die minmal schützbare Tonfolgen als Samples Baukasten.

Was ist die Menge an Musik, die ich mit diesen Samples Baukasten durch Kombinatorik (theorethisch) erzeugen kann?

(Ich meine, welche Musik lässt sich theorethisch mit diesen Samples als Basis etzeugen).

Keine Sorge, es bleibt den neuen Urhebern genügend Material, weil alle Musik, die nicht auf dem klassischen Notensystem oder Pentatonik basiert (wie 5/9 oder 17/33 oder sonstiger Bruch 2er hoher Primzahlen Tonschritte) lässt sich damit sicher nicht abbilden.

---

Suppose I take all the classical music compositions, that aren't subject of copyright (e.g. church modes, all modern classics before 1900, such as Bach, Mozart, ...) and use the minimum protectable tone sequences as a sample construction kit.

What is the amount of music that I can (theoretically) generate with these sample modules through combinatorics?
(I mean, what amount of music can theoretically be created with these samples as a basis). 

Don't worry, there is enough material left for new composers, that want to produce under copyright, because all music that is not based on the classical notation system or pentatonic scale (such as 5/9 or 17/33 or other fractions of high prime numbers) cannot be reproduced with it.

---

Supposons que je prenne tout le stock de musique classique qui n'est pas soumis au droit d'auteur (par exemple, les modes d'église, tous les classiques modernes avant 1900, tels que Bach, Mozart, ...) et que j'utilise les séquences de sons minimales pouvant être protégées comme un exemple de kit de construction.

Quelle est la quantité de musique que je peux générer (théoriquement) avec cet exemple de kit de construction utilisant la combinatoire?

(Je veux dire, quelle musique peut théoriquement être créée avec ces échantillons comme base). Ne vous inquiétez pas, il reste assez de matière pour les nouveaux auteurs, car toute musique qui n'est pas basée sur le système de notation classique ou l'échelle pentatonique (comme 5/9 ou 17/33 ou d'autres fractions de nombres premiers élevés) ne peut pas être reproduit avec.

Semantic web lost in history / herstory around 2010, how to reactivate it & a short contract use case

Current hypes, trends and pushed business models at 2020

Let's take a short look at the current hypes, trends and pushed business models for companies:

1. IOT (Internet of things), Industry 4.0
   Machines, units, etc. know and probably send their own status at manufacturer, service center, at home or somewhere else over the rainbow (in case of  ugly DNS injection, warped rouing tables [OSPF, BGP] ot men in the middle [squid bump, bluecoat, ...]).
   Those units normally,communicate when they need maintenance, when components soon needs to be replaced, when physical, technical or environmental critical limit reached, when subsystems fail or completley shut down, when the user when the customer operates it improperly or negligently, simply report in intervals that they are alive and everything's OK, , etc
   
   We can find a lot of use cases for many useful applications here, added value / surplus is often small but still useful! Problems with security, flood of data, extracting relevant events and, above all, reacting to the corresponding message are the challenges here.
   
   
   
2. Cloud
   I like the cloud, but sometimes cloud feels cloudy, cloudier, obscure dust and smog over keywords and hypes and real hard technical features that generate great customer surplius and real cash or quality of business benefits.
   
   What are the most common problems, pitfalls and misunderstandigs with any cloud?
   
   
   • Lack of specific customer requirements and inaccurate, exact technical specifications from the cloud provider.
     
     Practical example (what I really need and I'm thinking about right now):
     I need to implement a state service, that saves current game status of small multiplatform games (e.g. card game schnapsen, archon clone, SUPU) in the cloud. If I play on my  android tablet or smartphone, the current state and course of the game will be transfered to a cloud servie, persisted in a cloud storage or database and if I continue playing on Windows desktop, the last state of the game is automatically fetched from the cloud and the game application sets that game state and transferred back to cloud after the next move.
     
     For my purposes the cheapest way will be sufficient:
     A simple Amazon Linux 2 AMI (HVM), SSD Volume, Type t2.nano, t2.micro or t2.nano with a simple SQL-Database (no matter if hackish install at virtual imaage or the smallest Amazon DB instance) with somekind of open source PHP Swagger API, like https://github.com/andresharpe/quick-api
     
     With similar requirements, some developers and most managers are probably unsure whether to use Amazon ElasticCache or some kind of Session State Server ported to Azure SQL  or entirely another not well known cloud service.
     
     Even fewer people (including myself) know what the exact technical limits of the individual services are, e.g. the exact performance and scalable elasticity of Anazon Elastic Cache and when scalability of Amazon Elastic Cache is completely irrelevant, since the network traffic and the network data volume will always be the bottle neck in that specific scenario.
     
     
   • Nice advertising slogan, but poor performance and poorly configurable options from drive and storage providers, no standard network mount (like SMB or NFS), but a lot of cloudy magic.
     When I look at the beautiful Google Drive and Microsoft One Drive, I immediately see that this is not a classic network file system mount under my point of understanding.
     Reading and writing large blocks or deep recursively nested directory trees is extremely slow.
     I also didn't find an option to have an incremental version history backup created after every change (Create, Delete, Change) to the Cloud Drive or at least simply midnight-generated backups for the last 3 months at low cost.
     Options like synchronizing parts of the Cloud Drive locally create horror nightmares.
     In 1997 we booted an NFS from the USA via Etherboot with real-time DOS and debugged faster Doom Clones and other 3D games in C ++ with some ASM routines and the network performance didn't fail.
     
     
   • Difficulty finding the most suitable service in Cloud Djungel. Real technical comparisons between the hard facts and the possibilities of the individual cloud services have so far mainly published by free bloggers, e.g. AWS Lambda vs Azure Service Fabric
     Decisions are more based on creeds (we have a lot of .NET developers, so we'll use Azure, I mah strong Amazon-like power women and Linux, so I'll use Amazon).
   
   
   
   

Lets go back to RDF in the years 2010 - 2015 

You probably know what semantic web, owl, rdf, machine readable & understandable data are, right?

If not, then here is a little bit of reading:
https://www.w3.org/TR/rdf-mt/
https://www.w3.org/TR/2010/WD-rdb2rdf-ucr-20100608/
https://en.wikipedia.org/wiki/RDF_Schema

What does 'going back in time' mean in a large scope and broader sense?

Before all the new trends, there was an attempt to realize semantic web, e.g. RDF as an XML extension with semantic machine-understandable properties.

When we as human beeings read a website or analyze BIG data, we automatically recognize the context, perhaps the meaning and probably the significance of this data.

Machines can't do that, they didn't have a semantic understanding until now.

Information theory distinguishes between 3 levels of information:

1. Syntax level (compiler construction, scanner, parser, automata & formal languages, extended grammar, e.g. https://en.wikipedia.org/wiki/Context-free_grammar) 
2. Semantic level (meaningful reading by people, putting things into context, understanding contexts).
3. Pragmatic level (goal-oriented action based on information by recognizing the meaning at the level of semantics).

I assume / postulate:

=> If computer programs reach 2. semantic level => then we are a big step closer to AI realization.

Why computer programs can't already implement semantic understandig? 

Theoretically and also practically in terms of technical frameworks, computer programs are already able to understand semantically data.

The concrete problem is here, that too little data are provided in a semantically machine-readable form and a standardized (META-)language.

Example: Regardless of whether Statistics Austria, Open Data GV or ECB, etc, certainly provide very good statistics, but none of them provide semantic machine-readable data.

Somebody has to make here a  larger startup, to transform already provided common and needed statistics public data in semantically machine-readable form.

What does that actually bring in return of short time invest?

Not so much immediately!

What could be the fruits in mid-term or in the long tail?

A lot, because when more and more public open data are availible in a semantic machine readable language, programs can also bring some of them in association and we'll be able to implement meta relational AI rules then.

Use case contracts

Semantic programs doesn't only mean mass data fetching and putting them into relation. 

Semantic programming could also in principle support any very formal business process, e.g. contract management for

• employment contracts
• supply contracts
• service provider contracts
• insurance contracts
• bank contracts 
• and all the contracts that people sign with just one click on a checkbox (which they usually do not know that this is a legal contract consent).

All clear and understandable so far?

I got this idea when I was looking and inspecting the adopted amendment to the laws and newly passed laws by the democratic republic of Austria and I wanted some semantic automated statistics for some use cases.

Schlafstörungen, nächtliche Recherche und IBM Security

Aufgrund nächtlicher Schlafstörungen recherierte ich ein wenig, denn für ein komplett neues android system image kompilieren, war ich trotzdem viel zu müde.

Dabei fand ich diese netten IBM Security Produkte und noch ein par andere Dinge:

IBM's still alive

IBM Security Trusteer Mobile SDK

Hier gibts so ein trusted mobile device (andoid, iphone, tablet) SDK (Software Development Kit), das Kompromittierungen (root, hacked, jail-breaked, untergeschobene root-CAs um SSL aufzubrechen und evtl. Staatstrojaner und ähnliches erkennt). Jedenfalls sollten Entwickler damit sicherere verteilte Anwendungen für Cloud u.s.w. hochverfügbar implemetieren können:

https://www.ibm.com/products/trusteer-mobile-sdk

Mobile device management (MDM) solutions

Das hier ist auch so eine mobile security Geschichte, die mobile Geräte Sicherheit der Mitarbeiter garantieren will. Also so kein "Nachhause-Telefonieren" durch irgendwelche untergejubelten Drittanbieter Apps, klassische End-2-EndPoint Secuirty, u.s.w.

https://www.ibm.com/security/mobile/mobile-device-management

IBM Security Products (case study fraud detection)

Dann zeigt IBM weiter noch, dass es auch eine standardisierte Fraud detection (wahrscheinlich generisch erweiterbar) kann! Ich schätze diese Fraud Detection Engine geht wahrscheinlich über Insolvenzregister, KSV, Casinosperre, Standardbonitätabfragen und dubiose exotische Prepaid oder sontige WireCreditCards hinaus und lernt kontinuierlich (à la Virenscanner):

https://www.ibm.com/security/products

nomachine.com

Zu guter letzt fand ich noch einen sicheren Terminal-Server (diesmal nicht IBM, den sich auch mal wer ansehen könnte):

Gehe jetzt wieder ins Bett, gute Nacht / guten Morgen.

Warum ich der Welt grundlegend misstraue?

Die Zeitung "Die Welt" schrieb: "Ein Forschungsteam hat sich den Erfolg der deutschen Kapitalanlage im Ausland gründlich angeschaut. Dabei hat sich gezeigt, dass die Deutschen bei ihrer internationalen Geldanlage ähnlich erfolglos sind wie bei der Anlage ihrer Ersparnisse." "Andere Länder sind mit der Anlage ihres Auslandsvermögens deutlich erfolgreicher. Seit 1975 liegt die jährliche Rendite deutscher Anlagen im Ausland um fünf Prozentpunkte unter den Erträgen, die die USA erwirtschaften, und immer noch drei Prozentpunkte unter der Rendite, die die anderen europäischen Länder im Durchschnitt erwirtschaften." "Deutsche Anlagen im Ausland besser managen Allein im Zeitraum seit der Finanzkrise hätte Deutschland ein zusätzliches Vermögen im Umfang von zwei bis drei Billionen Euro aufbauen können, hätte es sein Geld ähnlich gut angelegt wie Kanada oder Norwegen. Pro Kopf der deutschen Bevölkerung entspricht das 28.000 bis 37.500 Euro! Auf einen Schlag hätten wir ein um 50 Prozent höheres Vermögen." "Was zu der folgenden Frage führt: Woran liegt es? Darüber kann man nur spekulieren. Um uns zu verbessern, sollten wir zwei Dinge tun: weniger im Ausland anlegen und unsere Anlagen im Ausland besser managen."

Web Link: https://www.welt.de/finanzen/plus226059659/Geld-fuer-die-Steuerzahler-25-000-Euro-fuer-alle-unter-65.html Screenshot: https://photos.app.goo.gl/MrvKFzFtgbqoW6vJ8 Äh, wieso muss Deutschland sein Vermögen im Ausland inverstieren? Performance der Börsenleitindezes einiger europäischer Staaten inkl. Schweiz. Wir sehen, der DAX stieg um 254%! Jetzt mal angenommen, die Deutschen hätten ihr Geld in der Schweden oder in der Schweiz angelegt: das wären ja immer noch satte 228% oder 132%. Von Signapur oder den USA rede ich jetzt gar nicht einmal, sondern nur von Europa. Selbst bei Investitionen in den Eurostoxx oder den italienischen Leitindex wäre das noch immer ein kleines Plus von 50%. Und bitte, Italien ist nicht unbedingt das kapitalistischte Land der Welt, oder? Europäisches Land Steigerung von 22.02.2009 bis 10.02.2021: Deutschland 354,19% Schweden 328,13% Schweiz 232,96% Eurostoxx 208,29% Italien 155,45% Griechenland 14,66%

P.S.: Was mich aber wirklich wundert:

Wie in aller Welt konnte Deutschland mit dieser hohen Staatsquote so extrem gut gegenüber der sparsamen liberalen Schweiz performen. Ich vermute, es liegt an den Freihandelsverträgen, die die EU genial aushandelte.

Ich vermute: Da die deutsche Wirtschaft auf Export ausgelegt ist, ist jeder Freihandelsvertrag ein Boost im DAX.

P.P.S.: EINE KLITZEKLEINE FRAGE:

Was hindert eigentlich die Deutschen daran, sich an deutschen Unternehmen zu beteiligen? Ich mein Mtarbeiterbeteiligung ist ein etwas moderneres, aber nicht gerade sehr neues sozialistisches Konzept, das bei so Betrieben, wie der VOEST Alpine, inzwischen sogar [Geschäfsgeheimnis] und [Geschäfsgeheimnis] in Österreich und sogar inzwischen einigen US amerikanischen Unternehmen oder japanischen Unternehmen Gang und Gebe ist. Sind aber alles Industrie- oder IT- Unternehmen. (bis auf Goldman Sachs), aber Nomen est Omen und dort ist immerhin der Sachse vergoldet und nicht Paria.

Welcher Mitarbeiter oder Manager von mittel bis CEO vertraut bitte dem eigenen Unternehmen nicht? Das klingt verdammt nach "Deutscher Bank" oder? Ich kann mir nicht vorstellen, dass ein BMW Mitarbeiter den bayrischen Motorenwerken nicht vertraut oder ein VW Mitarbeiter nicht den Guys in Wolfsburg oder Ingolsstadt. Ich würde sogar T-Systems vertrauen und dort mein Geld investieren!

No global plan for generic multi-language globalization/localizaion

There is sadley no generic concept for platform and language independent multi language globalization / localization for applications.

Some case studies

Visual Studio WinForms (C#, VB)

Globalization / Localization in Windows Forms is implemented via different resource files (.resx).

ResourceManager and Resource accessors are created semi automatically from Visual Studio.

Resources in .NET

Microsoft and Stockoverflow links about resources and globalization and culture info.

https://docs.microsoft.com/en-us/dotnet/framework/resources/

https://docs.microsoft.com/en-us/dotnet/api/system.globalization.cultureinfo

https://stackoverflow.com/q/32989100/12213151

Android Studio (Java, Kotlin)

Globalization / Localization are realised in Android Studio via different language directories beyond the res folder:

Using the Translation Editor inside Resource Manager to build your translation from Android Studio GUI, see: http://blog.androidrich.com/2016/11/translation-editor-in-android-studio.html

Android supports right to left screen orientation too for arab or farsi languages.

Razor MVC and Blazor Web

Webpages, that are build with .NET framework and deployed in IIS on windows or Apache on linux (no matter with mod_mono or something else [1]) use language and country prefix directly after FQDN and before path in url to route to different language subpages, e.g.:

https://docs.microsoft.com/de-at/aspnet/core/blazor/globalization-localization
https://docs.microsoft.com/fr-fr/aspnet/core/blazor/globalization-localization

Multi-language globalization in reality

In reality in the world wide web and on desktop or other applications, there are many different approaches how multi-language and globalization is implemented. Only few use a auto translation API like google.com/translate.

Prospect / outlook for standardized globalization?

I don't know. Lets use the crowd to answer that question!

n-sphere hypermaps ⇒ cattle breeding

Have you ever noticed the advantage of real n-sphere hypermaps?

No?

That is very sad, because with hypermaps thou would understand, recognize, realize immediately,

1. that alpine pastures for cattles offer little crop yield for humans;
2. that mordern technical agricultureof is nearly impossible in hilly and mountainous impassable areas with rocks and small swamps inside and only 2% continuous flat area per hectare.
3. that cattle breeding in certain climatic alpine mountainous regions has much lower risk as Agricultureof with poor hervests in worse case.
4. that cattles transforrm & recycle low-calorie vegetarian naural grown food much better than humans or hunter mammals with a short intestine.
5. that chances of success for cattle and sheep breeding are similarly much higher as profitable modern agriculture at Scottish Highlands in the marsh, around rual areas beside Loch Ness, on Outer Hebrides and on small isles (Inishbofin, Claire Island) near the Irish north-west coast.

linux: flashing an (iso)image to usb stick

This article contains all main informations to create (rawwrite) a bootable usb stick from an existing iso (loopback) image under linux.

classic way diskdump (dd)

Find correct usb device file 

First we had to find correct linux device file for your plugged/connected usb flash (e.g. lsblk):

  lsblk --list --fs ; lsusb -v ; lshw ; hal-device ; dmesg ; echo "..."

or use that (almost) auto usb devive verifying simple shell script:

get_usb_device() {
    local device_path=$1        # such as /dev/sdc
    for devlink in /dev/disk/by-id/usb*; do
        if [ "$(readlink -f "$devlink")" = "$device_path" ]; then
            # echo "$device_path" is usb device 
            # echo "$(lsblk -no NAME,FSTYPE,SIZE,STATE,OWNER,TYPE,MOUNTPOINT,LABEL,MODEL "$device_path")
            echo Fetching detailed information for usb device "$device_path" by 'hdparm -I "$device_path"'
            echo -en "$(hdparm -I "$device_path") \n\n"
            echo use cache size as base for block size in disk dumnp later 'bs=...'

            return 0
        fi
    done
	
    echo "$device_path" is not an usb device
    return 1
}

  REMOVABLE_DRIVES=""
  for _device in /sys/block/*/device; do
      if echo $(readlink -f "$_device")|egrep -q "usb"; then
          _disk=$(echo "$_device" | cut -f4 -d/)
          REMOVABLE_DRIVES="$REMOVABLE_DRIVES $_disk"
      fi
  done
 
  for _usbdevice in "$REMOVABLE_DRIVES"; do

    if get_usb_device "$_usbdevice"; then
      echo "# use following code to create your bootable usb stick: "
      echo sudo umount -l "$_usbdevice" ; 
      sudo dd if="$HOME"/'path_to_your_image.iso' of="$_usbdevice" bs=4K && sync 
      echo "# correct bs (block size) by cache size of usb device! "
    else
      echo failed verifying usb by executing command: get_usb_device "$_usbdevice" 
    fi

  done

Flash your iso image to usb device file with dd

Finally use linux disk dump (dd) for creating image.

  sudo umount -l  /dev/usb_device_to_flash ; 
  sudo dd if=path_to_your_iso_image of=usb_device_to_flash bs=block_size_based_on_devive_cache && sync ; 
  # default block site always are any factors of 4K

Advanced tools like Usbimager or WoeUSB

Using more advanced graphical tools such as usbimager or WoeUSB to create bootable USB flash stick.

hard fact reality vs narrative story telling (playing) theater from the point of triggers

Introduction 

The meaning of triggers in this article according to information theory. 

https://pediaa.com/difference-between-semantics-and-pragmatics/

https://pediaa.com/difference-between-semantics-and-pragmatics/

A trigger is an impulse that causes people or programmed machines to take certain actions after a message has been understood in both semantic and pragmatic context. Strong triggers include furthermore the feeling of high priority and generate a strong tendency to act, well as an awareness of the consequences of not acting now.

Some examples for triggers

1. Weather is stormy and rainy (semantically and pragmatically understood) ⇒  
   →  (Trgger) →  (T) →  
   ⇒  I have to open my umbrella
   
   
2. Fire breaks out ⇒ 
   →  (Trgger) →  (T) →  
   ⇒  Trigger fire alarm and call fire department
   
   
3. FED is lowering prime interest rate from 2,25% to 0,5%. ⇒ 
   →  (Trgger) →  (T) →  
   ⇒ Let's get a cheap credut (loan) in US$ and 
   make classical leverage invest in Dow Jones & Nasdaq!

Detect hard fact reality vs story telling theater by observing behavior of trigger

When I was in the army long time ago, we learned several emergency commands / orders. One of that was 'AC-Alarm' (Atomic nuclear, biological or chemical are launched, so troops had to immediately Initiate protective suit and emergency measures)

Nobody was ever maling many funny jokes in that training, similiar to fire breaks out ⇒ fire alarm in the examples above. When observing the trigger behavior. everybody recognizes, that this is no playing game and a real dangerous situation. Same story, when people are infected with HIV (AIDS) Virus or (not so deadly) Malaria.

Well, when looking at the Coronavirus, triggers are too soft, negligently, inconsistent.

Remember all Dioxin, Plutonium, Anthrax incidents in the last 25 years, remember even Creutzfeldt–Jakob disease. triggers were much more hard and serious, even when there was never danger for many people in all that cases.

According the media Coronavirus has already killed hundreds of thousands of alleged dead, but nobody's reacting or triggering heavy casualties for real. People are still playing that game, but nobody takes / triggers that Coronavirus real serious / grievous.

Snaps, snapd,, Snap Store, snapcraft.io

Tonight in the early morn, when I tried to write(1) an open os based solution(2) to transform almost any modern personal computer or laptop(3) to a simple generic wifi router(4).

Then I unexpectedly found a  community platform, that was still unknown to me:

snapcraft.io

Snaps are there defined as  app packages for desktop, cloud and IoT that are easy to install, secure, cross‐platform and dependency‐free. Snaps are discoverable and installable from the Snap Store, the app store for Linux with an audience of millions, 

I tried first the search functionality of that platform and let's say clearly: 

The layout design looks excellent, the community is well visited, but some functions could be better. Lets look at these 2 examples: 
Searching common phrase file
Searching 1 char only d  

Search results also could be sorted more meaningful & understandable, e.g. 

1. show all results, where the search phrase  directly corresponds to the package app name /(no matter if sql like (prefix, suffix, substring), sql fulltext match or Levenstein distance.
2. then show all results, where the search phrase is found in the shown package descripton
3. at least show all results, that appear like a magical fog or smoke for the user. I know, that your search function is probably not returning total random or bad fuzzy hit results, but I guess the search algorithm searches in fields, which are not shown in search result view.

Snapcraft web site provides at the moment the snap app package search page, a store, tutorials, documentation, developer blog, forum and IOT special bulletin.

Conclusio: Snapcraft has surly more potential, but additional functionality must be added and especially a more clear vision and road-map needs to be specified, followed and permanently filled with life. (Under my point of view, without any additional improvements, vision and road-map the project and the community won't grow up and then after some time, this will remain as small circle of developer project or even become orphaned.)
So far I see this nevertheless as an good opportunity for developers and community to get seen and to receive good jobs offers.

Simply said: Thou must have very soon an idea, where this should go and what exactly you want with  it. If thou don't want to expand and keep this project as a nice and gentle private hobby, then you can keep everything and don't have to change anything. But if you want to expand, become at least a small player for long time, ...

State management in Blazor

There is a sufficient document for state management in Blazor.
Here is a quick & fast work through with all prerequisites, how to get state management in Blazor working.

Example with Blazored.LocalStorage package

Install nuget package for your project

# Find packages providing a "Blazored.LocalStorage" 
Find-Package Blazored.LocalStorage

# install "Blazored.LocalStorage" 
Install-Package Blazored.LocalStorage -Project YourProject# alternatively

Add Blazored.LocalStorage to ConfigureServices at your Startup.cs

using System;
/* ... */
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
/* ... */
using Blazored.LocalStorage;

public class Startup {
  /* ... */  
  public void ConfigureServices(IServiceCollection services)  { 
    /* ... */
    services.AddRazorPages(); 
    services.AddServerSideBlazor();
    /* ... */    
    services.AddBlazoredLocalStorage();
    /* ... */
  }
}

Using LocalStorage inside a razor page / control

@page "/MyPage"
using Blazored.LocalStorage
@inject ILocalStorageService localStorage
@code {
  /* ... */
  Dictionary<string, string> sessionDict;
  /* ... */
  protected override async Task OnAfterRenderAsync(bool firstRender)  { 
    
if (firstRender)    {
      sessionDict = 
        await localStorage.GetItemAsync<Dictionary<string, string>>("SessDict");
      StateHasChanged();
    }    await base.OnAfterRenderAsync(firstRender);
  }
         protected async Task PersistSessionDict(<Dictionary<string, string> persistDict)
  {
    if (persistDict != sessionDict)    {
      await localStorage.SetItemAsync("SessDict", persistDict);
    }
  }
}

Using LocalStorage inside an entity class

using System;
/* ... */
using Blazored.LocalStorage;
 
public class MyEntity

Semantic Internet (former known as Semantic Web, see also RDF) has the possibility to record different semantic trends occurring at different sources with a certain frequency inside the in principle accessible to the public internet.
Day after day, month after month, semantic contexts are published on the Internet. area23 semantic web filters all semantic statements that occur with a certain frequency from different sources. Furthermore, not all trends and semantically significant events are more relevant for most semantic miners.

With area23 semantic web you can filter by region, topic categories, relevance from different sources and subsequent complexity.

A filter for a region can be set similiar to Google Trends, e.g. for United States or for Germany, etc.

Basic main categories are:

• politics (Brexit, Sinn Féin, Thüringen, ...)
• sports  (soccer, american football events, ...)
• entertainement (music, cinema, tv, ...)
• technology
• business (stock markets, trading, bonds, central bank news, different economic indictors)
• health
• lifestyle (eating, drinking, other events)
• housing (appartments, flat, hotel, camping / caravan sites, vacation rentals, accommodations, e.g.: Airbnb, Wimdu)
• infrastructure (traffic reports, flights & airports occupancy, train connections, ships & ferries connections)
• weather (including unexpected temperatures / weather effects, like ice, heavy rain, storm, dry periods plus enviroment disasters, like hurricanes, floodings, earthquakes, volcanic eruptions)
• and many more

Once you created your filter enviroment, you can start collecting & recording semantic events.

After some time, collected semantic events will appear, e.g.: 'coronavirus'

In that example, 'coronavirus' the most common and reliable semantic logical statements are shown (extracted from different internet sites / ressources), e.g.: number of infections, behavior to stay healty, flights canceled to / from China, stock market risk for China in the next year.

Every statement extracted from the data pool that directly makes a statement or an assumption regarding matters other than the corona virus is now checked with other data sources as to whether the statement actually has a formal fuzzy truth content. So in that (our) example, the flight connections from and to China will be verified immediately as a result. Chinese economic data and the change behavior of futures in Hang Seng, which changed in the period since the outbreak of the coronavirus, will be checked too.

Warning, formally epistemologically an extracted statement is not necessarily true, even if 15 different articles from different countries in different languages in the web claim: "Corona virus has negative effects on the current Chinese fiscal year 2020." and if the outlook for futures in Hang Seng and the economic data have deteriorated in the same period.

EPU Personenbetreuer in Vorarlberg & weiter stark (aber nicht mehr wachsend)

Im Jahr 2014 befasste ich mich rein privater Natur mit dem Wachstum / Entwicklung / Überhitzung der veschiedenen Wirtschaftssektoren, Sparten, Branchen, Fachgruppen, Berufsgruppen und sonstige kurzfristingen Trends und langfristiger Entwicklungen in den Bereichen Arbeit und Wirtschaft anhand des ganz konkreten Beispiels der Berufsgruppe Selbstständige Personenbetreuer.

Ich verfasste folgenden sehr kurzen Artikel auf meinem Blog hier dann dazu. Der Grund für gerade diese Berufsgruppe für jene Fallstudie war nicht etwa ein sozialer Hintergrund (z.B. arme ausgebeutete Scheinselbstständige im untersten Einkommenssegement)  oder ein rassistisches Motiv (es handelt sich bei Mitgliederinnen dieser Berufsgruppe vornehmlich um weibliche der Volksgruppe der Slawen zugehörige osteuropäische EU-Bürgerinnen), sondern ganz simpel und einfach die Tatsache, dass es in Österreich aufgrund der demographischen Entwicklungen in diesem Marktbereich sehr leicht einschätzen lässt, welche Nachfrage es durch immer mehr pflegebedürftige Pensionistinnen gibt und gleichzeitig welcher  Angebotsbedarf an Personenberteuerinnen (Pool an Betreuerinnen) dazu sich korrespondieren entwickelt.

Bis Anfang Jänner 2019 stiegen Angebot und Nachfrage in der Pflegebetreuung relativ konstant an (eine immer größer wachsende Anzahl von Pfelgebedürftigen mit immer exklusiveren Bedürfnissen stand korrelierend ein stetig wachsendes Angebot an Pflegeleistungen und immer mehr Betreuerinnen gegenüber).
Im fortschreitenden Jahr 2019 stagnierte allerdings die Angebotsseite deutlich zum 1. Mal seit Jahren und es gab kein sichtbares signifikantes Wachstum bei der Anzahl der sich anbietenden Personenbetreuerinnen.

Seit Anfang 2020 schrumpfte bereits die Angebotsseite sichbar. (sprich eine signifikante geringere Anzahl an vorhandenen selbstständigen Personenbetreuerinnen offerierte eindeutig nicht mehr derart manngfaltige Liestungsangebote, sondern viel mehr ein günstiges Standard-All-In Paket / Dienstleistung).

Staatsschulden Deutschland

Laut Statistik der Wirtschaftskammer Österreich sind die Staatsschulden von Deutschland die letzten Jahre extrem gesunken (von 82% des BIP 2010 auf 56,8% des BIP 2020 approximiert).

Quelle: http://wko.at/statistik/eu/europa-verschuldung.pdf

Trading-Economics bestätigt diese Daten:

Auch die EZB Daten bestätigen dieses Bild:

Details für Feinspitze gibt es hier:
https://sdw.ecb.europa.eu/browse.do?node=bbn3885

Alle unterschiedlichen Quellen bestätigen, dass Deutschland seine Staatsverschuldung in den letzten Jahren im Vergleich zur Wirtschaftsleistung (Brutto-InlandsProdukt) extrem reduzierte.
Ob Deutschland Investitionsbedarf im Bildungs- oder Infrastrukturbereich hat, kann ich nicht beurteilen, ich habe dazu leider keine Quelle.

Auf alle Fälle sitzt die Bundesbank immer noch auf einer beachtlichen Menge an (derzeit ungedeckten) Target Forderungen (Wer weiß schon was die Zukunft bringt)?
