Cloudflare blocked over 416 billion AI bot requests since July 2025, says CEO Matthew Prince. These crawlers from Google, OpenAI, and others scrape sites for AI training without paying.

Cloudflare’s β€œContent Independence Day” lets websites auto-block them, protecting creators from free data grabs while calling out Google’s search-AI crawler merge

πŸ—³ AI Influences Voters More Effectively Than Political Ads on TV

Chatbots are able to shape voters' political views more powerfully than traditional election advertising, researchers from the United States and Poland have found.

Before the American presidential election in 2024, scientists asked 2300 voters to rate the main candidatesβ€”Donald Trump and Kamala Harrisβ€”on a scale from 0 to 100 points. The study participants then communicated with chatbots that campaigned to vote for one of the candidates, either convincing the subjects (if they had opposing views) or reinforcing their opinions.

After people communicated with AI, the candidate's rating increased by 2-4 points, whereas traditional campaign advertising has an effect of slightly less than 1 point. Moreover, AI changed the views of the candidate's opponents more than it reinforced the beliefs of supporters.

πŸ“ˆ A similar experiment before the presidential elections in Poland and among voters before the federal elections in Canada showed an even greater effectβ€”their preferences towards the candidates shifted by an average of about 10 points after talking to the chatbot.

In the United States, the influence of AI was weaker due to the entrenched polarization of opinions between supporters of Trump and Kamala Harris, scientists say. Whereas in a less tense situation in other countries or in local elections, the chatbots' influence was more noticeable.

πŸ’― Interestingly, AI models tend to be more persuasive when they focus on facts, not emotions. Chatbots that explained the candidates' political agendas with clear arguments earned far more trust than those that focused on the politicians’ personalities.

🧠 Advanced Tech Reality Check (Read Carefully)

At an advanced level, more tutorials won’t help you.

What actually separates senior-level builders πŸ‘‡

βš™οΈ 1. You Think in Trade-offs, Not Tools
Frameworks change. Principles don’t.
You choose tech based on latency, scale, cost, and failure modes.

πŸ“ 2. You Design Before You Code
Clear architecture > clean syntax.
Data flow, bottlenecks, observability, rollback strategy β€” before writing code.

πŸ” 3. You Treat Security as a Default
Auth, rate limiting, secrets management, threat modeling.
Security is not a feature. It’s a mindset.

πŸ“Š 4. You Measure Everything
Logs, metrics, traces.
If you can’t observe it, you can’t improve it.

πŸš€ 5. You Ship, Monitor, Iterate
Advanced devs don’t chase perfection.
They ship fast, monitor behavior, and refine in production.

🎯 Hard Truth:
Senior-level skill is about decision quality under constraints, not writing clever code.

This channel is for people who want to think like engineers, not tutorial followers.

πŸ’» Computer Chips = The Real Power Behind Your PC

Computer chips (microchips) are tiny silicon processors packed with billions of transistors.
They handle all the thinking and tasks inside computers, phones, and smart devices.

πŸš€ Impact on Performance

Your computer speed depends on chips because they control:

Cores β†’ more cores = better multitasking

GHz speed β†’ higher = faster calculations

nm size β†’ smaller = more powerful + less heat

Cache β†’ speeds up data access

GPU chips β†’ boost gaming, editing & AI


⚑ Strong chip = fast apps, smooth games, quick rendering, cool system.

🏭 Who Makes These Chips?

Top chip fabricators (manufacturers):

TSMC β†’ world’s biggest (makes chips for Apple, AMD, NVIDIA)

Samsung Foundry β†’ phone & computer chips

Intel β†’ designs & manufactures its own chips

GlobalFoundries β†’ IoT & some AMD chips


(Most companies design chips, only a few build them!)

Why Electronics Circuits Are Gold for CS & Software EngineersπŸ€“

Circuits aren’t just wires and resistors β€” they’re how computers speak and think.

Why learn them as a future software/CS engineer?

They power logic (1/0) β€” the language behind every program.

They make computer architecture, CPUs, and memory easier to master.

They level up your debugging & problem-solving like competitive programming does.

They open doors to IoT, embedded systems, robotics, and AI on hardware.

They help you write smarter, faster, and optimized software.


Bottom line:
Circuits turn you from a coder into an engineer who understands the machine under the code.

CSE vs Software Engineering: Which is the Better Choice?

πŸ” Computer Science & Engineering (CSE)

Focuses on theory, algorithms, data structures, AI, and hardware.

Pros: Broad career options (AI, Robotics, Cybersecurity), strong foundation in math and system design.


βš™οΈ Software Engineering

Focuses on software design, development, and lifecycle.

Pros: In-depth software development knowledge, high demand in Web, Mobile Apps, and Game Development.


🌟 Key Evidence:

CSE grads have a versatile skill set, suitable for many roles.

Software Engineering grads are highly sought for their specialized software development skills.


πŸš€ Conclusion:

CSE is ideal for a broad computing career.

Software Engineering is best for those focused on software development.
(Note: This comparison is international; in Ethiopia, especially at ASTU, both are often seen as similar.)
