Finally got the RHCSA!
I promised myself on December 30th that I’d start checking off my goals, and this is the first one down. Just one box ticked so far, but it feels great to see progress.
RHCE is already loading… we move!
Going into 2025 with a bang! 🚀 RHCSA, RHCE, RH294, and Podman—all will be in the bag next year. Courses + exams = no excuses. Stay tuned as I tick them off one by one!
This is my reality, and I'll pursue it madly. Enough of the fears for certifications. 💪 #RedHat#RHEL
Some people don’t have solar. They have expensive rechargeable lamps connected to panels. Because how do you spend millions on a solar system and still cannot explain:
What load it was designed for
How many kWh the battery can deliver
How long the backup should last
How many panels are recharging it
What happens after two cloudy days
What loads should not be connected
A proper solar system should be designed around your actual energy use, not around "this inverter is strong" or "this battery is foreign used but very good".
Before you pay for solar, ask for the numbers.
Inverter size.
Battery capacity.
PV size.
Expected backup duration.
Load assumptions.
Protection devices.
Monitoring plan.
If the answer is "don’t worry, it will carry everything", please worry. Solar is too expensive for vibes.
@JustinTimeJLew@TreadLightly23 Good one man, I gave up at RHCE. I prepared for the exam but refused to take it. Just because I no longer find purpose in it.
Day 5 - Supply chain idea bank🧵
Today I built my supply chain project idea bank. I assumed this would take 20 minutes. It didn’t. Writing ideas that actually reflect operational problems forced me to slow down and rethink what I consider portfolio work.

Day 4 - Skills Audit 🧵
Today I evaluated the difference between knowing tools and actually executing with them in real projects.
Uncomfortable honesty - but necessary for growth.

Day 3 / 120
Spent time today revisiting a Power BI portfolio project built on a pharmaceutical sales dataset focused on tracking revenue against targets using YTD measures in DAX.
While reviewing the dashboard, something didn’t sit right with the outputs:

Take this advice from someone who’s heard a lot of no’s… and a lot of silence.
Do your thing alone if you have to.
Put your heart into it and trust your vibe.
Keep showing up, even on the quiet days.
It might take time, but you’ll get there.
You’ll be fine.
NERC is rolling out something new called Net Billing.
It’s a simple idea: if you have solar, you use what you need, send extra power to the grid, and get credits on your bill.
for dummies:
it’s really simple → the funding fees traders (long/short) pay each other add up to billions.
sometimes low single-digit billions to tens of billions.
calculating $ETH total funding paid was easy.
the numbers are even bigger for $BTC (the #1 crypto asset), big enough to make your brain hot.
another interesting angle is: a lot of this value isn’t just vanishing into thin air.
vaults running delta-neutral strategies (hedging price risk, farming funding) are collecting them.
funding rates are small numbers but when amplified with leverage and high capitals, the rewards are attractive especially when you compound.
my next digging is how to survive spikes in borrow rates.
the hidden killer of “risk-free” yield.
this industry needs more credit.
looking back at 2023, before the shanghai upgrade (EIP-4895) for staked ETH withdrawals…
staking ETH was a one-way street:
you deposit → it gets locked indefinitely → you earn yields. that’s it.
participation stayed low because no one wants to lock their ETH forever.
then withdrawals went live.
staking became liquid in both directions. stakers could come and go.
that changed the game for LST (forever):
more ETH flowed into staking, participation increases, and the shift began.
people chased higher yields or switched providers.
then restaking came (thanks to eigenlayer & co).
validators are now able earn double yield on their staked ETH.
LSTs became a double-edged yield source.
non-validators could also buy LSTs on the open market, restake them, and get LRTs (liquid restaking tokens) in return.
LRTs are composable too, you can plug them back into DeFi: lending, trading, looping strategies.
now we’re in the next phase: structured products + perps → making yield itself becomes tradable.
protocols have built on top of LSTs and LRTs:
– yield vaults (auto strategies like yearn, euler finance)
– structured products (fixed vs variable yield splits, e.g. pendle PTs/YTs)
– and now perpetuals (@nunchi) where you long or short the rate itself.
this transforms ETH yield into a complete interest rate market.
you don’t just “earn it,”
you trade it, hedge it, speculate on it.
only few knows.
