React Hooks are the functions which "hook into" React state and lifecycle features from function components. Hooks allows you to manipulate state and other React feature without writing a class. Let's talk about widely used hook

useEffect hook at a glance 🧵👇🏻

useEffect hook is the heart of React functional components

If you're familiar with class components then you might know that we have various lifecycle methods but in functional components, we don't have any lifecycle methods. Instead we have a powerful hook called useEffect

By using useEffect, you tell React that your component needs to do something after render. React will remember the function you passed (we'll refer to it as our “effect”), and call it later after performing the DOM updates

So let's start by understanding the syntax first

3/15

useEffect take two parameters, first is a function and second is an array.

The function inside the useEffect will run every single time component re-render. Consider this piece of code and check the output in next tweet

{ 4 / 15 }

As you can see in the output the function is executed every single time my component re-render

{ 5 / 15 }

Just published 15,000+ words on security keys. 🔐📱💻

With SIM attacks at their highest, now is a great time to take a closer look at your online security.

Removing SMS from your two-factor auth is a start, but authenticator apps have downsides too...

Just look at these headlines from recent SIM swap and port attacks.

It's all too established for attackers to find ways to socially engineer control of your phone number and start gaining control of your accounts.

I first talk about some general security tips.

Unfortunately not all websites let you remove your phone number from accounts.

You may consider migrating your phone carrier to @googlefi , which requires email account access to do anything (and can be locked down with security keys and even Advanced Protection)

Beyond SMS, I talk about issues that TOTP authenticator apps (the code generators) have as a form of two-factor auth. They're so, so much better than relying on SMS for your second factor but they still have issues like utilizing shared secrets and lacking phishing prevention.

Enter security keys!

Utilizing public key cryptography they don't have any shared secret between the client and the server. They prevent phishing by taking the website domain into account.

Even if you get tricked by a clone phishing website, your key won't.

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

@RubinReport Your commentary on the dangers of silicon valley coming under the spell of wokeness and cancel culture is spot on. I know this to be true because in Bitcoin we have already lived through a similar culture war against crypto anarchists.

We experienced firsthand the tactics such groups use to eliminate ¨wrongspreak¨ from public debate. And as you rightly recognize, this exact thing is currently happening in society as a whole. And not surprisingly often by the exact same people.

For example, Jack Dorsey, investor in and honored by the BTC cult, is the same person responsible for the twitter bans of many people, including a lifelong ban for the former president of USA. BTC ideology and such policies may seem incompatible with each other, but it is not.

As we stood up against social engineering and the destruction of language in Bitcoin we have been demonitized and deplatformed. Evidence: Just read the whitepaper and see how BTC, what they tell you is Bitcoin, doesn´t even come close to it.

So, just like you, we have been busy building our own alternative platforms based on new incentive structures and the Own Your Data philosophy.

For example have a look at this excellent presentation on @twetchapp

LIVE: ❄️ City of Austin leadership including @AustinEnergyGM will address the unprecedented severe weather.
💻 Due to tech limitations, it will only be available via Facebook Live here: https://t.co/PchiwUgP0M
We will be live-tweeting in this thread.

Mayor Steve Adler: This will require us all to come together and help one another.
City Manager Spencer Cronk: As a City, we are doing our best to help those in need.

Cronk: Stay off the roads and conserve energy. Every little bit helps.

COA Office of Homeland Security and Emergency Management Director Juan Ortiz: Currently we have a warming center at the Palmer Events Center. You can show up at any time. As of this morning, cold weather shelters remain active. 282 were sheltered overnight.

Ortiz: Urge residents to conserve much power as possible to help with the emergency issues. We are working with critical facilities to ensure that access to those facilities remain open, so ambulances can get in.
