TEC Client Explorations

Establishing A Connection

When making a telnet/socket connection to game.eternalcitygame.com:6730, the type of protocol engaged by the game server depends on what you send after it prompts you with Login:.

Telnet Data Format

Handshake: /\/Connect: n/a!!n/a
Login: You'll be prompted to enter your username and password (not hashed). The server's telnet implementation does not support TLS.
Example output: The following is output from Blightmud, note the missing first character on words with i= RGB colours. This is because there are escape characters encoded here, and the parser for Blightmud (and other clients like VIP mud), escape the next character after them removing it from output.

Git Things

Useful things you can do with git.

• Cross-repository issue tagging:
  • [org/repo#407]
• Reset local branch to match origin (throw away local commits):
  • git reset --hard origin/<branch_name>
• See diff between local and remote:
  • git diff origin/main..HEAD
• See files changed between local and origin after a fetch:

What Is This?

A place where I keep learning resources that I've found useful. Started as a list for my team at work, but will likely continue to grow outside that over time.

A chunk of the training courses here are pluralsight as it's what we've had access to at my company traditionally. That being said I'll try to find similar resources for non-pluralsight subscribers as times goes on; it just happens to be a go-to spot for Microsoft-stack teachers and developers.

Books

• C# 9 and .NET 5 - Modern Cross-Platform Development
  • https://www.amazon.com/NET-Cross-Platform-Development-intelligent-Framework/dp/180056810X/ref=zg_bs_697342_1
  • The book takes a very modern approach to MS Stack C#/.NET using VS Code, but it contains a lot of history of the language and framework, a lot of "how we got here", and language fundamentals.

If you lock your Windows 10 machine and find that after a period of time (1 minute? 3 minutes?) it goes to sleep and the displays turn off. You may have a value set in a hidden Power Option menu.

1. Open the registry and go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7
2. Change the value of 'Attributes' from 1, to 2.
3. You should now see the Console lock display off timeout options under the Display menu in Power Options for a given profile.
4. Set the Setting propery for both On Battery\Plugged In to 0 to force it off.
5. ???
6. Profit

Steps for setting up a decent looking WSL Ubuntu terminal

Install and configure the WSL/Ubuntu console:

• Enable WSL on Windows 10 through 'Programs and Features'.
• Install WSL Ubuntu from the Windows Store.
• Launch ubuntu.exe and do initial 'Properties/Defaults' config:
  • Right click on the title bar, select Defaults:
    • Under the Options tab, select Use Ctrl+Shift+C/V as Copy/Paste
    • You might want to increase Buffer Size for Command History under the Options tab, and Height under Layout > Screen Buffer Size: 9001 seems like enough 😄

# This script gets the DNSNames of two defined Route53 domains (one is a subdomain of the other),
# and swaps the aliases to perform a blue/green deployment. Or for whatever other reason you can imagine.

# Note: If you were doing this for two different non-subdomain domains; you'd have two Hosted Zone Ids here:
$hostedZoneId = '<some-hosted-zone-id>'

$stagingDNSAlias = aws route53 list-resource-record-sets `
    --hosted-zone-id $hostedZoneId `
    --query "ResourceRecordSets[?Name == 'staging.yoursite.com.'].AliasTarget.DNSName" `
