Real Me

This has to be near the peak of sentiment for Trump.
Absolute euphoria around the world.
2025 Presidential Inauguration is gonna send it.

I am curious what it will feel like in 9 months 🤔

NEW VIDEO ALERT 📽️🚨:

Are you trying to figure out what to $HODL ? 🪙

Orange ya sick of worthless sh*t coins that dump? 🍊

Tired of greedy KOL's who don't give a 🐀🍑?

Enter: HODL

@valueandtime called this forever ago and it was an IMMEDIATE no-brainer 🧠🤯

All you had to do was HODL the orange....

@AdobeCare Im deleting all apps and files.

Theres loose "leftover files" from the past 7 years, Adobe application manager, CC related files.

They cant be uninstalled unless all the other adobe apps are uninstalled.

I finally figured it out. Never downloading Adobe on a general pc again.

[Christian Nastri @CryptoHeckler]

These corporate apps that you have to download are pervasive parasites in your computer.

I just failed at uninstalling @Adobe suite. It says other applications require it, and I dont want to force uninstall and miss something.

Had to download another security app to handle it.

[Christian Nastri @CryptoHeckler]

@AdobeCare Ya thats exactly what Im talking about is the issue.

A 14 step guide, downloading another app to deal with these apps, manually searching through directories. I have no idea what all this is and why I need apps that download the apps.

Recent cyberattacks targeting MGM Resorts and Caesars Entertainment exposed huge vulnerabilities and risks to guest data security. Lets look into the technical aspects of these breaches and some defense insights.

Understanding the Attacks:
Both MGM Resorts and Caesars Entertainment fell victim to social engineering attacks that began with deceptive "vishing" calls. These calls aimed to manipulate IT service desk personnel into resetting MFA factors for highly privileged users, granting threat actors access to administrator accounts.

MGM Incident: VX-Underground attributed the attack to the Alphv/BlackCat ransomware gang and a threat actor known as Scattered Spider. The attackers disrupted casino operations and gained control of Okta authentication servers.

Caesars Breach: Caesars confirmed the attack and disclosed that an "unauthorized actor" had stolen data, including sensitive information such as Social Security and driver's license numbers.

David Bradbury, chief security officer of the identity management company Okta, said FIVE of the company's clients, including MGM and Caesars, had fallen victim to hacking groups known as ALPHV and Scattered Spider since August.

The massive hacks epitomize a vicious ransomware threat that is always looming.

Insights to Prevent Social Engineering Attacks:

Employee Training: Educate employees to recognize and respond to phishing attempts, including vishing calls, through regular security awareness training.

MFA Enhancement: Strengthen MFA policies, considering advanced solutions to fortify security layers.

Proactive Monitoring: Implement robust monitoring systems to swiftly detect unusual activities, particularly around privileged accounts.

Leveraging Threat Intelligence: Collaborate with cybersecurity partners and draw insights from third-party threat intelligence reports to identify threats and stay updated on evolving risks.

Secure Authentication Flows: Regularly audit and secure authentication flows, especially for highly privileged users, to mitigate potential vulnerabilities.

Recognize that cyber threats extend across industries, requiring continuous vigilance.

*To protect your privacy, inquire about the deletion of personal information collected by casinos for reservations and loyalty programs. Familiarize yourself with data protection regulations in your travel destination for added security.*

Credit Card Security: Monitor credit card statements diligently, as casinos often store credit card information for guest expenses. Consider locking your credit files to mitigate unauthorized access risks.

Elevating Cyber Hygiene: Strengthen your cybersecurity practices with robust measures like intricate, unique passwords and two-factor authentication for accounts and mobile apps. When downloading applications, use official sources to avoid counterfeit versions.

Utilizing Resources: Enroll in transaction alerts to monitor credit card activity for financial security. Take advantage of identity monitoring services offered by affected organizations to detect potential identity theft early.

Navigating Complex Cyber Threats: Cyber threats are continually evolving into sophisticated forms, and data sharing among companies can pose challenges in securing every potential access point.

In conclusion, while vigilance is paramount, adopting stringent cybersecurity practices is equally crucial. Embrace these practices to proactively protect your personal information and financial assets against the looming specter of cyberattacks in our digitally interwoven world.

Solidity Fact of the Week: Storage of Mapping Data
The mapping data type used for state variables doesn't have a fixed size in storage, unlike arrays. This means that, theoretically, you can have an infinite number of key-value pairs in a `mapping`. However, a unique feature is that every possible key already "exists" in a mapping with its value set to the type's default. For example, in a `mapping(address => uint)`, if you query an address that hasn't been set explicitly, it will return `0` rather than an error. Because of this behavior, you can't iterate over a mapping's keys or count them directly. If iteration or counting is needed, additional data structures or patterns must be implemented alongside the mapping.

The inherent behavior of mappings in smart contract development simplifies code, improves efficiency, enhances predictability, optimizes storage usage, and contributes to the overall security of blockchain applications. It is a fundamental feature of many smart contract languages, including Solidity, and plays a crucial role in their design and functionality.

Efficiency: This feature allows for efficient and constant-time lookups. When you query a key that hasn't been explicitly set, it returns a default value (usually 0 for numeric types), avoiding the need for error handling or additional checks. This simplicity in handling uninitialized keys contributes to gas cost savings in blockchain environments like Ethereum, where gas costs are a critical consideration.

Predictability: Developers can rely on the default behavior of mappings. This predictability simplifies smart contract development and reduces the potential for unexpected errors due to uninitialized variables. It aligns with the principle of least astonishment, making code more intuitive.

Storage Optimization: Unlike arrays, mappings don't reserve a fixed amount of storage upfront. They allocate storage dynamically, saving space by not preallocating storage for all possible keys. This dynamic allocation is especially valuable in scenarios where storage costs are a concern.

Security: By returning default values for uninitialized keys, mappings mitigate the risk of accidental bugs or vulnerabilities related to uninitialized variables. This behavior encourages developers to handle key initialization explicitly, promoting more robust and secure code.

@ChurchsChicken
The Church’s Chicken app is the worst fast food app I have seen.
- no rewards program
- unnecessary items in primary menu like Terms sheet
- 90s style aesthetic
- no profiles or accounts

Don’t be scammy like all the others. Make the customers feel appreciated.

The apps that fast food restaurants have now make me feel like I am ordering some supplies from an office store. The connection is missing, communication is bad, and often trust is missing as a result.

The app should make everyone feel better about the deal.

A good example of an elevated and more inviting experience is the @PandaExpress app. The app uses a standard points reward system, but also in-app games, bonus prizes, and enhanced communication.

The reaction from the user is very different. Bonus prizes make you giddy with anticipation when you are not on the app, leading to more attention. Games and puzzles add value to the app and build a rapport.

Last, Panda Express will sometimes give you coupons for giving feedback after a purchase. They understand the value of that information and how appreciated the customer feels.

In a few months, I will publish my paper on the next generation of price discrimination and how customizing the user experience can change your customer base.
