Not getting interviews in 2026? 😔

95% of the time it’s your resume.

Here’s a 0-bullshit thread that actually fixes it and gets you calls.

[Ihtesham Ali @ihtesham2005]

A Norwegian neuroscientist spent 20 years proving that the act of writing by hand changes the human brain in ways typing physically cannot, and almost nobody outside her field has read the paper.

Her name is Audrey van der Meer.

She runs a brain research lab in Trondheim, and the paper that closed the argument was published in 2024 in a journal called Frontiers in Psychology. The finding is brutal enough that it should have changed every classroom on Earth.

The experiment was simple. She recruited 36 university students and put each one in a cap with 256 sensors pressed against their scalp to record brain activity. Words flashed on a screen one at a time.

Sometimes the students wrote the word by hand on a touchscreen using a digital pen, and sometimes they typed the same word on a keyboard. Every neural response was recorded for the full five seconds the word stayed on screen.

Then her team looked at the part of the data most researchers had ignored for years, which is how different parts of the brain were communicating with each other during the task.

When the students wrote by hand, the brain lit up everywhere at once.

The regions responsible for memory, sensory integration, and the encoding of new information were all firing together in a coordinated pattern that spread across the entire cortex. The whole network was awake and connected.

When the same students typed the same word, that pattern collapsed almost completely.

Most of the brain went quiet, and the connections between regions that had been alive seconds earlier were nowhere to be found on the EEG.

Same word, same brain, same person, and two completely different neurological events.

The reason turned out to be something nobody had really paid attention to before her work. Writing by hand is not one motion but a sequence of thousands of tiny micro-movements coordinated with your eyes in real time, where each letter is a different shape that requires the brain to solve a slightly different spatial problem.

Your fingers, wrist, vision, and the parts of your brain that track position in space are all working together to produce one letter, then the next, then the next.

Typing throws all of that away. Every key on a keyboard requires the exact same finger motion regardless of which letter you are pressing, which means the brain has almost nothing to integrate and almost no problem to solve.

Van der Meer said it plainly in her interviews.

Pressing the same key with the same finger over and over does not stimulate the brain in any meaningful way, and she pointed out something that should scare every parent who handed their kid an iPad.

Children who learn to read and write on tablets often cannot tell letters like b and d apart, because they have never physically felt with their bodies what it takes to actually produce those letters on a page.

A decade before her, two researchers at Princeton ran the same fight using a completely different method and ended up at the same answer. Pam Mueller and Daniel Oppenheimer tested 327 students across three experiments, where half took notes on laptops with the internet disabled and half took notes by hand, before testing everyone on what they actually understood from the lectures they had watched.

The handwriting group won by a wide margin on every question that required real understanding rather than surface recall.

The reason was hiding in the transcripts of what the two groups had actually written down.

The laptop students typed almost word for word, capturing more total content but processing almost none of it as they went, while the handwriting students physically could not write fast enough to transcribe a lecture in real time, which forced them to listen carefully, decide what actually mattered, and put it in their own words on the page.

That single act of choosing what to keep was the learning itself, and the keyboard had quietly skipped the choosing and skipped the learning along with it.

Two studies. Two countries. Same answer.

Handwriting makes the brain work. Typing lets it coast.

Every note you have ever typed instead of written went into your brain through a thinner pipe. Every meeting, every book highlight, every idea you captured on your phone instead of on paper was processed at half depth.

You did not forget those things because your memory is bad. You forgot them because typing never woke the part of the brain that would have made them stick.

The fix is the thing your grandmother already knew.

Pick up a pen. Write the thing down. The slower road is the faster one.

If you understand IP subnetting well
You can monetize it by:
Applying as
Junior Network Engineer or Associate

Network Engineer
Network Support Engineer / NOC

Technician (Network Operations Center)

Network Technician / IT Support Specialist

(Mid level )Network Administrator

Network Engineer

Cloud Network Engineer (AWS VPC, Azure VNet subnetting)

And (expert level) as:
Network Security Engineer

Telecom Engineer or Wireless Engineer

IP Resource Analyst or IP Number resource Specialist

You can also Offer 1-on-1 tutoring/coaching for CCNA students or professionals struggling with subnetting (platforms: Preply, Upwork, Superprof).
Provide network design/audit services: efficient IP addressing schemes, cloud subnet planning (AWS/Azure), or troubleshooting for businesses and ISPs.

[ADEWOLE @AdewoleofGod1]

You can get started with this resources:

Jeremy’s IT Lab (YouTube): Widely considered the best free CCNA course. It includes free flashcards (Anki) and lab files for every video.

Cisco Packet Tracer (Software): The essential "Home Lab" simulator. It’s free from Cisco Networking Academy. You can build entire networks on your laptop.

FlackBox CCNA Lab Guide: A free 300+ page PDF that walks you through practical configurations.

Keith Barker (YouTube): Excellent for "Subnetting Saturdays" and deep dives into specific tricky topics.

Highlights of the new proposal

[TheSophisticatedDumbTechGuy @TheDumbTechGuy]

We're trying to get airtime to discuss the approach NITA is trying to use to heavily regulate tech professionals.

As a short brief.

Tech is what it is because individuals can simply learn and become employable or even self employ themselves without any extra pain.

This is the second proposal since last year, this time NITA is proposing penalizing any private or public institution that hires tech folk who are not certified by them.
This completely goes against the ethos of the industry and will lead to a lot of problems.

if you haven't gotten what you want, then you're not worthy of it. And that's okay. Now you can admit that you suck and improve. Better to know you're bad for a season than pretend you're good for a lifetime.

You're not making as much money as you want because you're not as good as you think you are. You're not struggling from impostor syndrome. You're a student and pretending to be a teacher. No students say they feel like frauds trying to learn. You're a fraud when you get up to teach the class and you've never done it.

AI has stopped being a feature and started being the foundation.

We're excited about a new wave of startups rebuilding software, services, and silicon— and pushing AI into the physical world.
