Bridge Mini-VM for reading XFS, JFS, ext[234], minix, btrfs, reiserfs ot any other non MS filesystem
Howto access XFS, JFS, ext[234], minix, btrfs, reiserfs ot any other non MS filesystem from Windows 7 - 11 without installing a maybe bogus kernel filesystem driver?
- Make a Mini-Vm with a totally slack and stripped linux kernel, that is bridged on a VM network adapter. Include all filesystem drivers and needed network adapter & drivers in that kernel and strip / kick out everything other, what's not needed.
Make the kernel similiar to a cisco router or PIX firewall kernel. - Give the VM direct access to your harddisk, usb-devices, firewire & bluetooth devices.
- Enable the Mini linux VM to reEXport mounted filesystem over smb or nfs.
- Calculate the memory size, which is needed, that all filesystem mounts and all fs operatons work fast enough with paging and caching.
- Choose the best scheduler for that mini-VM.
- Optimize all ioctl, (f)lush, (f)read, (f)write, (f)seek, (f)open, (f)close and all other filesystem operations.
- If you are hungry => oprimize the /proc /sys /dev filesystem.

A crazy example of a Lazy singleton as strangest singelton pattern ever
Application settings example:
BaseSets for basic settings as abstract singelton base

public virtual string AppName { get; protected set; }
/// <summary>
/// protected empty constructor for inheritable singelton

/// <summary>
/// protected parameterized constructor for inheritable singelton

protected BaseSets(int appId, string appName)
{
AppId = appId; AppName = appName;
}
}
}
AppSets for application settings as instancable singelton default app sets (settings):
using Microsoft.Win32;
using System;
using System.Reflection;
using System.Windows.Forms;

some ideas to Azure & Microsoft SQL Servers [Draft]
What is missing?
It's missing, that we have unfortunatley no consistently implementation for Active Directory (see also: LDAPS, X.500) on Micrsoft SQL-Server.
How fast are Linked Servers & Distributed Transaction coordinator
Trust me, they are really fast and OAUTH and Azure Auth would be implemented in some weeks, if MS put some lower evangelists at work!
To be continued ...

Fact checking: What come from pirate party and socialist section8 and what from communists?
In the years 2011 - 2014 I was an more left as (but still) liberal activst participating at serveral discussions in the free internet in different forums or social media.
From my point of view, many ideas that were produced together in common with stakeholders from pirate party and section8, had the most politically and avangardistic value and also flowed partially into the party program of other parties (e.g. Neos, SPÖ, even partly Greens, ÖVP, FPÖ).
I will list here the most impactfully issues:
I. Transparency
I.1. Transparency (freedom of information) Act
Feb 12, 2013, 7:34 PM
Vor 10 Tagen haben Sektion8 & Piratenpartei die Petition zum Transparenzgesetz veröffentlicht:
https://blog.area23.at/2013/02/am-222013-machten-mich-sektion-8-und.html
Sektion 8 wollte doch Akkzente setzen und nicht nur reagieren.
In dem Fall ist das sehr gut gelungen.
Gratulation, bei so einer wichtigen Sache.
Liebe Grüße,

Betreute Personen => kein unabhängiger Patietenanwalt (rechtlich, medizinisch) und mangelnde Menschenrechte & Monitoring
Viele Menschen in Österreich benötigen Betreuung, sind pflegebedürftig, in Lebenskrisen (durch Schicksalsschläge, Schocks, Obdachlosigkeit, Gewalteinwirkung, Resozialisierung nach Aufenthalt, Aufenthalt in einer psychiatrischen Anstalt oder im Strafvollzug, Betreung von schwer Demenzkranken oder (Halb-)Komapatienten, oder chronische schwere Seuchen bzw. Suchtkrankheiten).
Egal um welche vom Leid getroffenen Menschen es sich nun handelt (sehr alte Senioren mit schwerer Demenz, Härtefälle betreut vom psychosozialen Dienst, in psychiatrische Kliniken zwangseingewiesene oder wohnungslose, die jetzt im sozialen Wohnen Programm sind, betreute WGs für Menschen mit Behinderung, ...), es gibt KEINE unabhängige Kontrolle und Monitoring und es gibt keinen Garant, dass jeder dieser Menschen eine rechtlichen und medizinischen Patientanwalt regelmäßig kontaktieren kann.
Was sind die Konsequenzen des Fehlens einer unabhängigen Kontrolle und eines unabhängigen Patientenanwalt?
Ein par Fallstudien (leider aus der Realität)!
- Eine albanische Flüchtlingsfrau (ohne Bildung) steht nach Mißbrauch unter schwerem Schock. Aufgrund des Schocks gingen alle kommunikativen Fähigkeiten (einfache Sprache, Gebärden, Deuten, Nicken) bei ihr temporär oder ev. parmanent verloren. Die Frau hat permanent große Angst und wird in einer Einrichtung des PSD (Psychosozialen Dienst) betreut. Es ist unklar, ob Leute, die in den Mißbrauch verwickelt waren, sich auch in der Einrichtung befinden und keine Garantie, ob sich die Frau von dem Trauma unter gegebenen Umständen überhaupt abkapseln, erholen, regenerieren kann.
- Ein WG-Bewohner in einer betreuten WG für Menschen mit Behinderung fühlt sich von seinen Mitbewohnern und den Betreuern schikaniert und gequält. Dem armen ist es unmöglich sich nur 2 Stunden in der Woche zurückzuziehen, um Musik zu hören, ein par schöne Erinnerungsfotos anzusehen oder ein Buch ein par Seiten zu lesen.
- Ein auf einen Asylbescheid wartender nordafrikanischer Flüchtling wurde vom Flüchtlingslager aufgrund seiner Sexuakität und permanenten Stockschlägen in der Nacht auf eine psychiatrische Einrichtung verlegt. Zwar zufrieden über den besseren Schutz und keiner Folter, ist der Flüchtling in Sorge, dass er wichtige rechtliche Termine zu seinem Verfahren nun versäumt und so dann automatisch abgeschoben wird.
