Bitcoin mining – is it worth it?

Note: This is just a brief article on my personal opinions on getting into bitcoin mining.

Bitcoin Mining is one of those things – I feel you really had to get in early to do.

In order to make bitcoin mining worthwhile is to get a ASIC setup and join a Bitcoin mining pool.

For a single user using CPU or GPU power to mine – not worth it. The cost of your power usage outweighs any worthwhile mining.

Note: However you can get ASICMiner Block Erupter USB powered drives to do your mining for you – allowing you to build your own mining platform running cheaper than if you were to have your GPU working full time.

Using exchange to automatically accept meeting requests

Having multiple mailboxes and calendars can be hard to manage – especially when meeting requests don’t automatically accept themselves.

Using a quick powershell cmdlet from the Exchange Management Shell you can quickly set a calender to AutoAccept meeting requests

Set-MailboxCalendarSettings "mailbox name" -AutomateProcessing AutoAccept

Note: Remember to run the Management Shell as Administrator.

Common Protocols and their ports

Networking is a marvel of interconnected devices and languages – part of that inter connectivity is allowing devices to talk to one another without getting any crosstalk or confusion this is done by separating network traffic into ports – allowing traffic to be managed easier and allows for overall greater security.

HTTP (Hypertext Transfer Protocol)
HTTP uses port 80 – this is usually used for web traffic – for webpages.
HTTPS (Hypertext Transfer Protocol SSL)
Similar to port 80 although this is using port 443 – this is used for secure and encrypted traffic and used for website logon pages and secure VPN connections.
FTP (File Transfer Protocol)
Using port 20 and 21 – this is used for FTP traffic to and from.. used to upload webpages and files and folders from one host to another .
POP (Post Office Protocol) – Also POP3
POP and POP3 uses the port 110 – this provides the ability to receive emails – commonly used by ISPs email service.
SMTP (Simple Mail Transfer Protocol)
SMTP uses the port 25 – this provides the ability to send emails – commonly used by ISPs email service.
IMAP
Uses TCP and UDP port 143 – IMAP is another email service that is commonly used by email providers that hold emails on their servers – instead of downloading them to the local computer.
Telnet
Telnet uses port 23 – and is commonly used for remote administration of devices using a command line.
