In my quest to write a fast IPv4+6 parser, I have written a slow-but-I-think-correct parser, to use as a base of comparison.

In doing so, I have discovered more cursed IP address representations that I was previously unaware of.

A thread!

We start out simple, with IPv4 and IPv6 in what I'll call their "canonical form":

192.168.0.1
1:2:3:4:5:6:7:8

Various specs call these "dotted quad", dot-separated fields each representing 1 byte; and "colon-hex", colon-separated fields each representing 2 bytes.

The first bits of complexity come from IPv6. In canonical form, common addresses would end up with long runs of zeros in the middle. So, "::" allows you to elide 1 or more 16-bit blocks of zeros:

1:2::3:4 means 1:2:0:0:0:0:3:4

Next up, for cursed historical reasons, IPv6 permits you to write the final 32 bits of the address in dotted quad form. Effectively, you can splat an IPv4 address onto the end of IPv6 addresses!

1:2:3:4:5:6:77.77.88.88 means 1:2:3:4:5:6:7777:8888

And of course, you can combine the two!

fe80::1.2.3.4 means fe80:0:0:0:0:0:102:304

Wanna disable Defender when enabled Isolated Core and Tamper protection?

Its a bit more trouble- but doable, without ruining Isolated Core/Secureboot etc.

Defenders process will run as a unkillable protected service- so new tricks needed.

Here we go:

Ok- tamper protection is easy, just make .bat - run as adm:
:again
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WdFilter\Instances\WdFilter Instance" /v altitude /t REG_SZ /d -1 /f
goto again

Then unload minifilter with process hacker:

The registry key will be changed while the minifilter do not protect it, when tamper protection makes the driver load again it cannot attach to volumes nor protect registry keys.

Removing it will make it recreate, but invalid altitude do the trick

Notice now the service is: Protected light(antimalware)
Now we cant do anything to the service/process- not even see its open handles.

Lets start by elevating to SYSTEM- just launch a command prompt, then close process hacker- and run it again from the command prompt.
Now process hacker runs as SYSTEM

Twas the night before Christmas and all over the ‘net,
Not a creature was stirring except a few cyber threats
The firewalls were configured at the egress with care,
But that wouldn’t stop us from being hit by ransomware. 1/

The children were nestled all snug in their beds,
While attackers hit the web server and established a beachhead
Mama with her EDR and I with my IDS
Were ready to tackle this hot infosec mess. /2

Down in the SOC there arose such a clatter,
I logged into my dashboard to see what was the matter.
This thing had better work, it cost so much cash.
How in 2020 can this thing STILL require Flash?! 3/

The alerts lit up the dashboard, it produced such a glow
But it’s because the threshold for alerting was configured so low.
When what to my wondering eyes did appear,
But 300 false positive alarms. I thought “I’ll be here all year.” 4/

Then a little old DLL, signed by SolarWinds,
Was really the Russians, masters of supply chain break-ins.
We need some new vendors said the CISO, and the salespeople came. 5/

One of my purposes for 2021 is to simplify Docker for beginners.

Let's start with some definitions:

🏠Docker host
⚙️Docker engine
❓ Docker client
📝Dockerfile
📑Docker Image
🐳Docker Container
🐙Docker Compose
🪣 Docker Registry
🐳🐳🐳Docker Swarm

Definitions Below 👇

🏠Docker (Active) Host

A computer with Docker installed and the daemon running.

It can process Docker and non-Docker workloads.

⚙️Docker Engine

A Client-Server application. It has 3 components:

- "daemon process": A server that is a type of long-running program.

- "Rest API": to specify interfaces that programs can use to talk and interact with the daemon.

- "CLI": A command-line interface client

❓Docker Client

It sends commands to dockerd, using the Docker API.
It can communicate with multiple daemons.

📝Dockerfile

It's a text document that contains all the commands a user could call on the command line to assemble an image.

If you're interested in DB internals, stop what you're doing and watch @CMUDB Quarantine Talk from Nico+Cesar about @SQLServer's Cascades query optimizer: https://t.co/FCdsbHHEaD

Many talks this semester were good. This one is the best. My thread provides key takeaways

[6:50] Microsoft hired Goetz Graffe in the 1990s to help them rewrite original Sybase optimizer into Cascades. This framework is now used across all MSFT DB products (@SQLServer, @cosmosdb, @Azure_Synapse).

[14:43] The optimizer checks whether it has stats it will need before cost-based search. If not, it blocks planning until the DBMS generates them. This is different than other approaches we saw this semester where DBMS says "we'll do it live!" with whatever stats are available.

[21:05] Their Cascades' search starts small/simple and then they make decision on the fly whether to expand search based on the expected query runtime and performance benefit from more search.

[26:33] They explicitly have a property for Halloween Problem. Operators specify whether they protect from it and then optimizer ensures property is satisfied. This is mindblowing. I have never thought about using the optimizer for this but it makes sense.

Has this man been concealing his true identity?

Is this man a supposed 'dead' Seal Team Six soldier?

Witness protection to be kept safe until the right moment when all will be revealed?!

Who ELSE is alive that may have faked their death/gone into witness protection?

Were "golden tickets" inside the envelopes??

Are these "golden tickets" going to lead to their ultimate undoing?

Review crumbs on the board re: 'gold'.

Rani Chennamma of Kittur was one of the first women rulers of India who fought against the might of the British Empire in 1824. Rani Chennamma was born in 1778 in a small village of Kakati in Belgaon distt of the State of Karnataka.

She was born into the Lingayat Community to a man named Dhulappa Desai. From a very young age she was trained in horse riding,sword fighting, archery and diplomacy. At a very young age of 15 yrs, she was married to the King of Kittur and became the Queen of Kittur.

It is said that King of Kittur Mallasarja was once moving around in the neighbouring kingdoms to find support to fight Tipu Sultan. It is then, when he came across Chennamma and he immediately got attracted to her sheer confidence and bravery.

Rani Chennamma and King Mallasarja had a son together who died very soon after the death of King Mallasarja in 1816. As the Queen of Kittur, Rani Chennamma immediately adopted Shivalingappa as her son and declared him the heir to the throne of Kittur.

This did not go well with the British East India Company who was enforcing the Doctrine of Lapse those days, according to which the adopted children of the Indian rulers were not allowed to become their heirs and if the native rulers did not have children of their own, their...

Gather round, Gentle Readers. It is time I tell the story of the worst decision I ever made in an office. Some of you have heard this. Some have not. Whatever you do in your office today, this week, the rest of this year, you can console yourself by recalling this tale.

A long time ago, I was a talent agent. I worked for a woman named Susan Smith, who had her own small boutique agency. She was known for three things:

1. She had fantastic taste in clients. If there is someone you admire, odds are good that at some point, she was their agent,

2. She could negotiate a deal like few who have ever trod the earth. Casting would give her all the money they had budgeted for that part, plus a little more, plus promising to get her dog Barnaby groomed. She was magnificent to watch.

3. She was insane.

I'm sure you're thinking, "Quinn, it's the entertainment industry, they are all insane." Yes, many are. So consider this; if you told someone you worked for Susan, people who worked for insane people would look and you and whisper, "I hear she's insane."
