- Bill Gates gave an interview where he committed $2 billion to new energy research and argued the US government invests too little in energy R&D compared to other fields like pharmaceuticals.
- The document discusses how governments and states play a key role in high-risk basic research before private companies invest, citing examples from the internet and computing. It also references an economics professor who argues private companies only invest after the state takes on most risks.
- It analyzes the close relationship between governments, especially the US, and the oil industry, noting lobbying against alternative fuels and how reliant some states are on oil exporters, suggesting this hinders investment and progress on new energy sources.
Reactive Extensions (Rx) originated in the .NET world, devised and built by Erik Meijer and his team at Microsoft, Rx is a library to compose asynchronous and event-based programs. Available, among other languages, for Javascript(RxJS) it is meant for usage in frontend and backend programming. In this session we will see an introduction to Rx, why it is so useful to deal with async computation and how you can use RxJS in your code.

This document discusses the benefits of modular CSS and different methodologies for implementing it. It notes that CSS at scale can be difficult to understand, reuse, and maintain without modularity. It then explains Object-Oriented CSS (OOCSS), Block Element Modifier (BEM), and Scalable and Modular Architecture for CSS (SMACSS) as approaches for creating reusable, self-contained CSS modules. The key principles across these methodologies are separating components into logical blocks, elements, and modifiers; using descriptive naming conventions; and avoiding nesting and IDs. Following modular best practices makes CSS more predictable, maintainable, and performant at any scale.
The IT discipline of machine learning has become increasingly important in recent years. It promises to solve types of problems for which normal software development is considered unsuitable or too costly.
This document summarizes the evolution of Redux action creators from plain objects to functions that return action objects, and then to functions that return functions that dispatch actions. It discusses how middleware like Redux-Thunk and dependency injection allow async logic and testing of action creators. Redux-Saga is introduced as providing a cleaner way to write complex asynchronous action creators using generator functions. Key benefits of Redux-Saga include easy testing and ability to create daemon processes using patterns like takeLatest and takeEvery.
Body language is an important form of nonverbal communication that conveys 90% of the actual message. It includes facial expressions, eye movements, posture, gestures, and other physical behaviors that can communicate feelings like boredom, interest, disagreement, and more. However, meanings of certain gestures can vary across cultures. Being aware of students' body language through good eye contact, posture, positioning, and mirroring can help teachers create trust and understanding in the classroom. Overall, understanding body language can lead to more success in various aspects of life.

Yêu cầu: Hai server cấu hình Active - Active và sử dụng chung một Disk_Cluster (Trên SAN STORAGE) hay nói cách khác là 2 Server sẽ sử dụng chung một ổ trên SAN STORAGE để ghi dữ liệu vào đó.
(Bình thường nếu theo cơ chế Cluster thì trong tại một thời điểm thì chỉ có một Server được phép truy cập vào vùng Disk đó để ghi dữ liệu và Server còn lại chỉ dự phòng không được phép truy cập vào vùng disk đó, khi server chính bị sự cố thì
Server dự phòng mới được truy cập.
Sau đây mình sẽ hướng dẫn bạn cấu hình Cluster File System theo mô hình Acitve/Active để cho 2 Server cùng truy cập cùng một lúc để lưu và đọc dữ liệu như một ổ Share bình thường.

1. Cách dùng VEEAM Backup v9 sao lưu vCenter Appliance từ ESXi Host cũ và khôi
phục sang ESXi Host khác
Sau đây tôi giới thiệu 1 bài Labs thực hành về phương pháp sao lưu/ khôi phục hệ thống
VMware vSphere vCenter Server Appliance 6 thông qua công cụ Back/Restore chuyên
nghiệp – số 1 Thế giới VEEAM Backup Free version 9.
– Cách dùng VEEAM Backup Free v9 backup vCenter Appliance 6 từ 1 ESXi Host cũ và
khôi phục sang 1 ESXi Host khác
(Trường hợp: do không có Share Storage/SAN chung cho các ESXi Host, chỉ có 1 máy ảo
VM có hệ điều hành Opensource/MS Server như: Openfiler/FreeNAS hoặc WIndows
Server 2012 làm Software NFS)
Các bước chuẩn bị cho hệ thống VEEAM Backup:
Bước 1. Cách cấu hình VEEAM Backup Free v9
Tải bản ISO cài đặt VEEAM Backup Free v9
Cài hệ thống VEEAM Backup Free v9 xin tham khảo:
Cấu hình VEEAM Backup Free v9 trên 3 mô hình chính:
Cài trên 1 VM windows 2012 R2
Cài trên 1 Hyper-V và có windows 2008 R2/ W2K12/W2K12R2.
Cài .Net framework 4.5, SQL Express2013 Sp1
Bước 2. Cách viết script cho VEEAM Backup trên PowerShell v2
– Nội dung file VEEAMBackup.ps1 script:
##################################################################
# User Defined Variables
##################################################################
# Names of VMs to backup separated by comma (Mandatory). For instance, $VMNames
= “VM1”,”VM2”
$VMNames = “VCVA60”
# Name of vCenter or standalone host VMs to backup reside on (Mandatory)
2. $HostName = “10.10.11.80”
# Directory that VM backups should go to (Mandatory; for instance, C:Backup)
$Directory= “E:Backup_K2”
#Optionally, you can change compression level and desired retention, disable VMware
quiescence, enable encryption or even notification settings:
# Desired compression level (Optional; Possible values: 0 – None, 4 – Dedupe-friendly, 5
– Optimal, 6 – High, 9 – Extreme)
$CompressionLevel = “5”
# Quiesce VM when taking snapshot (Optional; VMware Tools or Hyper-V Integration
Components are required for this in the guest OS; Possible values: $True/$False)
$EnableQuiescence = $True
# Protect resulting backup with encryption key (Optional; $True/$False)
$EnableEncryption = $False
# Encryption Key (Optional; path to a secure string)
$EncryptionKey = “”
# Retention settings (Optional; by default, VeeamZIP files are not removed and kept in
the specifiedlocation for an indefinite period of time.
# Possible values: Never, Tonight, TomorrowNight, In3days, In1Week, In2Weeks,
In1Month)
$Retention = “Never”
#If you like to get an email report once the backup is completed, you should additionally
fill out the following notification settings.
##################################################################
# Notification Settings
##################################################################
# Enable notification (Optional)
$EnableNotification = $True
# Email SMTP server
$SMTPServer = “”
4. $CompressionLevel -DisableQuiesce:(!$EnableQuiescence) -AutoDelete $Retention
}
If ($EnableNotification)
{
$TaskSessions = $ZIPSession.GetTaskSessions().logger.getlog().updatedrecords
$FailedSessions = $TaskSessions | where {$_.status -eq “EWarning” -or $_.Status -eq
“EFailed”}
if ($FailedSessions -ne $Null)
{
$MesssagyBody = $MesssagyBody + ($ZIPSession | Select-Object
@{n=”Name”;e={($_.name).Substring(0, $_.name.LastIndexOf(“(“))}} ,@{n=”Start
Time”;e={$_.CreationTime}},@{n=”End
Time”;e={$_.EndTime}},Result,@{n=”Details”;e={$FailedSessions.Title}})
}
Else
{
$MesssagyBody = $MesssagyBody + ($ZIPSession | Select-Object
@{n=”Name”;e={($_.name).Substring(0, $_.name.LastIndexOf(“(“))}} ,@{n=”Start
Time”;e={$_.CreationTime}},@{n=”End
Time”;e={$_.EndTime}},Result,@{n=”Details”;e={($TaskSessions | sort creationtime -
Descending | select -first 1).Title}})
}
}
}
If ($EnableNotification)
{
$Message = New-Object System.Net.Mail.MailMessage $EmailFrom, $EmailTo
$Message.Subject = $EmailSubject
$Message.IsBodyHTML = $True
$message.Body = $MesssagyBody | ConvertTo-Html -head $style | Out-String
$SMTP = New-Object Net.Mail.SmtpClient($SMTPServer)
$SMTP.Send($Message)
}
Bước 3. Cấu hình PowerShell V2 cho phép chạy, read/write/executive trên máy chủ
Windows chạy bản VEEAM Backup Free v9.
Lưu ý khi lần đầu cài Microsft PowerShell vàchạy trên máy PC mới:
Gõ lệnh trên màn PowerShell / cmdlet / cmdDOS :
Get-PSSnapin
5. Gõ lệnh kiểm tra quyền chạy WinRM kết nối tới Office 365 (O365):
net start winrm
winrm get winrm/config/client/auth
Gõ lệnh cấu hình lại quyền chạy winrm (nếu kết quả báo: Basic=false):
winrm set winrm/config/client/auth @{Basic=”true”}
Một số trường hợp đặc biệt, máy PC của bạn đang join domain và bị Global
domain ngăn cản bằng các Policy domain hãy gõ lệnh sau để thiết lập quyền kết
nối và điều khiển Office 365 bằng PowerShell:
Set-ExecutionPolicy RemoteSigned
Set-ExecutionPolicy Unrestricted
Nếu là bị GPO hạn chế quyền restrictedpolicy hãy gõ lệnh sau:
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy unrestricted -force
Thêm vào đó 4 dòng lệnh sau:
Set-ExecutionPolicy -Scope LocalMachine -ExecutionPolicy unrestricted -force
Set-ExecutionPolicy -Scope MachinePolicy -ExecutionPolicy unrestricted -force
Set-ExecutionPolicy -Scope UserPolicy -ExecutionPolicy unrestricted -force
Set-ExecutionPolicy -Scope Process -ExecutionPolicy unrestricted -force
Tham khảo link: https://thangletoan.wordpress.com/2013/08/08/su-dung-powershell-
trong-office-365/
Bước 4. Cấu hình Task Schedule trên Windows > Administrator Tool cho phép chạy
Script theo lịch trình thời gian (onTime, on daily, on weekly, on Monthly…)
6.
7. Bước 5. Kiểm tra history kết quả backup của VEEAM Backup Free v9
8. Phần khôi phục lại máy chủ ảo VCVA trên một ESXi Host khác, sau khi đã backup
VEEAM v9 thành công.
Bước 1.
– Mở VEEAM Backup chọn Menu HOME > chọn nút Restore
Chọn thư mục và tìm tới file đã backup máy chủ ảo VCVA
9. Chọn bản đã backup gần nhất để restore
Chọn kiểu Restore Entire VM
Chọn vị trí ESXi Host khác để restore VM
10. Chọn từ Host mặc định cũ: 10.10.11.80 và chuyển sang Host khác: 10.10.11.70
11. Đã chọn sang Host khác.
Cuối cùng là phần Datastore để chứa máy chủ ảo VCVA cần khôi phục, bạn sẽ phải trỏ
tới 1 trong các vùng lưu trữ như: DAS, SSD, Local storage, SAN, NAS, Share Storage
mà có thể kết nối thông với ESXi Host vừa trỏ tới.
12. Lưu ý: vùng trống để chứa và vận hành máy chủ ảo VCVA có kích thước tối thiểu:
(114,3 Gb + 8Gb (swap file for memory ~ 8Gram/1 VM)
Bước 2. Kiểm tra kết quả khôi phục:
13. Bước 3. Kiểm tra máy chủ ảo VCVA:
– Bật máy ảo vCenter Server 6 sau khi đã khôi phuc thành công từ VEEAM Backup
– Mở console vCenter Appliance 6 và kiểm tra tình trạng chạy ổn định
14. – Mở IE/FF kiểm tra web vsphere client
Chúc các bạn thành công với việc bảo vệ máy chủ vCenter Server Appliance an toàn.
