There is stronger legal protection for more sensitive information, such as:

• race
• ethnic background
• political opinions
• religious beliefs
• trade union membership
• genetics
• biometrics (where used for identification)
• health
• sex life or orientation

There are separate safeguards for personal data relating to criminal convictions and offences.

Michael Porter - Estratégia Competitiva

 

Qual a teoria de Michael Porter?  Estratégia Competitiva.  

As 5 forças de Porter são: 

1) ameaça de produtos substitutos; 
2) ameaça de entrada de novos concorrentes; 
3) poder de negociação dos clientes; 
4) poder de negociação dos fornecedores  
5) rivalidade entre os concorrentes. 
São os pilares de uma empresa, e se algum mudar, deve-se reavaliar seu posicionamento estratégico

Qual a principal contribuição de Michael Porter para a gestão estratégica?

Do seu trabalho resultaram conceitos de estratégia que marcaram a disciplina como a análise de indústrias em torno de cinco forças competitivas; e as duas fontes genéricas de vantagem competitiva: diferenciação e baixo custo

Vis.js - JavaScript

Dygraphs is probably one of the fastest rendering charts I have come across, especially when the data set is vast. This library can handle data sets going into the tens of thousands and still deliver a great user experience.

• Easy to work with data, simple arrays, or load from text or CSV files

The one drawback to all this glory is that it’s completely based on line graphs. No bars, pies, or anything that you would usually see in a JavaScript charting library. Not to worry though, it’s still an epic package, and here’s why.

Licensing - 

Dygraphs is licensed under the MIT License which offers usage, modification, and distribution by both personal and commercial parties.

Windows 11 em Dell

 Quando o Microsoft Windows 11 foi lançado, as atualização automáticas do Microsoft Windows 10 deu como resultado do diagnóstico automático de hardware que o Windows 11 não podia ser instalado no meu notebook Dell Inspiron com processador Intel de 7a. geração. E durante vários meses eu tentei instalar o Windows 11 no notebook Dell e sempre aparecia a tela dizendo que não pode instalar.

Em Julho/2022 eu li um artigo na internet falando que o UEFI tem que estar ativo funcionando para o Windows 11 poder ser instalado; então eu olhei o setup do meu notebook Dell, no item em segurança eu vi que o UEFI aparecia como desligado, então eu desativei o item Legacy, e ativei o UEFI, e gravei a alteração do Setup do notebook Dell.

Então eu peguei um disco rígido USB de 1TB e fiz o backup 100% de todos os arquivos que eu utilizo, que estavam dentro do disco rígido 1tb do meu notebook Dell. Como o disco rígido do notebook Dell não é SSD, esse backup demorou uma semana para concluir.

Depois do backup USB pronto, eu copiei o Windows 11 para dentro de um pendrive USB 8gb, e mandei o Windows 11 começar a instalação, como eu gosto de fazer instalação limpa, mandei o Windows 11 excluir a partição do disco rígido, depois mandei o Windows 11 criar uma partição nova no disco rígido, e depois mandei o Windows 11 formatar o disco rígido, e assim começou a instalação do Windows 11.

Depois disso, eu notei que fazer a instalação do Windows 11 utilizando a rede wireless é muito lerdo, iria demorar muitas horas para a instalação concluir, então para o download e instalação ficar rápido, eu liguei direto um cabo ethernet do meu roteador wireless até o notebook Dell.

Em Julho/2022 eu consegui fazer a instalação do Windows 11 Home Single Language funcionar em um notebook Dell com processador Intel de 7a geração. Eu estou gostando muito de usar o windows 11.

TPM no Windows 11

TPM (Trusted Platform Module) = é um padrão internacional para processamento seguro, ele é um controlador que protege o hardware de seu computador com uma chave criptográfica única integrada ao mesmo. A versão mais recente do TPM é 2.0 

O TPM tem ainda uma ampla gama de funções como chave de segurança de hardware, identificação de dispositivos, autenticação criptográfica e verificação de integridade; o TPM faz 2 coisas principais:

1 - Cálculo de chaves criptográficas: a geração ou verificação de senhas no computador usando criptografia incorporado. Essas senhas podem ser travas de criptografia para discos rígidos, códigos de recursos usados por sistemas operacionais para verificar sua integridade.

2 - Armazenamento de chaves criptográficas: O TPM também é uma unidade de armazenamento de criptografia no computador, que não só calcula a chave criptográfica. 

O TPM verifica a integridade do sistema quando o Windows fosse inicializado, para funções de segurança.
