Public open Geopolitical Service

US debt clock permanent risk

 

Opponents of the US, play with the US debt.clock and nay at the right time play that card and that will bring US only in little turbulence, when the FED still works as usual.

Still right tending movement 

 

There is still a right spin pushment / movement in many societies.
Stake Holders and key players are here the not so often in party or in job successful  older male base and local federal state radio stations and press and internet forums.

 

Less Fact / Argument  based discussion, more political brawling 

 

Fact based argument based moderated expert talks disappear from many TV channels.

 Opinion from mostly republican politicians become more weighty and important,

while CEO of big companies or expert seem to have less weight and importance in public discussion / dis-curs. 

Nobody ask either Goldman Sachs or Prof, at university about the opinion next 2-4 years budget,

 

Argument; The budget from the Democrats will trigger too high debts (if many experts and several calculation proove it) 

Right pushing; Democrats brought so much criminal aliens into US (even if in fact criminality is all time low!

Mobile Devices → end of Flash, Silverlight, Moonlight, Java Applets, ActiveX

When it comes to browser plugin technologies like Flash, Silverlight, Moonlight or even old Java Applets, I claimed today in the early morn, that those tehcnologies began to die with the raise of mobile devices (most with a unix kernel) and mobile browsers. 


In fact it was the <object>...</object> tag in html, that whose full implementation of all technologies subsequently implied an excessively long and complicated process for mobile device and browser developers.


Died arround 2020 or earlier


https://en.wikipedia.org/wiki/Adobe_Flash

There may exist some flash browser under android, 
but the came too late:

https://en.wikipedia.org/wiki/ActiveX





Html5 + Css with Javascript (TypeScript, Angular) remains


There isn't really an alternative for browser plugin languages we had.  Html5 + Css with Javascript and all derived JS Framrworks like Node.js, TypeScript, Angular cannot map all features of Flash or Java Applets.

linux encrypting security

This blog article concerns linux encrypting security with public/private key (gpg, RSA, ...) mechanism and X509 certificates hierarchical security.

 

Levels of linux security  

 

UEFI Secure boot










Encrypted filesystem 

Linux Unified Key Setup 

Full Disk Encryption on Linux with LUKS

  

 https://www.linux.com/training-tutorials/how-encrypt-linux-file-system-dm-crypt/ 


filesystem mounting options: fstab

security options: readonly nonexecutable nosuid nosgid 

You can mount /usr as readonly filesystem and remount it rw on updates.

mount -o remount rw  /usr
apt-get update; apt-get distupgrade 
mount -o remount=ro=recursive  /usr

C# JetBrains Rider on Ubuntu Linux Wayland X11.

I tried JetBrains Rider on Ubuntu Linux Wayland X11.

 

Console Application

 

It's easy to publish a console application.
You must install in any way this Nuget package:
https://www.nuget.org/packages/System.Runtime.Extensions 

You might install additional Nuget packages, when using Resources.resx files and System.Drawing.Bitmap:
https://www.nuget.org/packages/System.Resources.Extensions
https://www.nuget.org/packages/System.Drawing.Common
 

 You can publish the application native x64 linux with that settings

 

or portable framework dependent. 

 

Asp.Net Blazor Application

 

But you can also build, publish, and launch an Asp.Net Blazor application. This animation shows you how to:

Market competition - where it's useful and where it's definitely not

Market competition among mobile network providers

There are several mobile network operators in the Austrian market. 

In the past (before year 2000), the market was mainly dominated by Mobilkom
a subsidiary of Telekom Austria, which was itself a subsidiary of Austrian Post


When we look at the market shares of mobile network operators, some only see the job cuts at the former Mobilkom. However, nobody calculates the number of new jobs created by the competition or considers whether there are now more jobs overall for mobile network operators in the Austrian market than during the near-monopoly era.

 

precarious jobs 

There are always people, including rarely some german economists, who call for more competition in the precarious job sector. 

Simple moving companies with small trucks charge at least €38-€50 per hour and don't work for less than an hour. You can only book them for one hour or more.

Distributing printed advertising flyers costs €0.11 per piece at the post office.
Private distribution agencies in Vienna often charge between €39 and €60 per 1,000 pieces for distribution alone. It's nearly impossible to find a reputable offer below that price. 
Lowering prices in the precarious segment risks poor or no service at all. (Some advertising leaflets end up in the trash and there is no legal company at all behind it.)

Trying to cut prices in the lowest price segment almost never works; there, the key is to offer better guaranteed performance and quality. Customers in the lowest price segment are almost always interested in guaranteed performance and quality, and rarely in a price reduction of 0.01 cents. 

Prices that are too low often cause customers to fear that the required service will actually be provided or not.
