A Small Throwback to Folding@home

Before crypto, before AI hype, before GPUs became financial instruments, there was a time when spare CPU cycles quietly went to science.

In the early 2000s, whenever I repaired a PC or laptop (which was 99.5% pro bono), I used to do one extra thing:
install Folding@home.

I’d explain to the owner that when their computer was idle, it would donate a tiny bit of electricity and processing power to medical research. Protein folding. Cancer. Alzheimer’s. Real problems. Real science. Electricity was cheap, machines were slow, and nobody expected anything in return – except the quiet satisfaction of contributing.

It wasn’t flashy. There were no tokens, no dashboards promising ROI, no buzzwords. Just a screensaver showing abstract molecules twisting in silence, doing something meaningful while the machine waited.

Fast forward to today. GPUs cost a fortune, watts are measured like fuel, and almost every spare cycle is expected to justify itself financially. And yet… Folding@home is still there. Smaller, quieter, a bit forgotten – but still running. Still doing the work.

I recently stumbled upon my old stats and noticed something funny: I was ranked #1 in my team by points, despite having fewer completed work units. Turns out the system always rewarded impact, not volume. Faster machines, harder simulations, better use of time. That feels oddly consistent with the whole philosophy back then.

No hype. No shortcuts. Just doing the job well.

This isn’t really about idle computing any more.
It’s about a broader shift in mindset.

Back then, the idea that many people could contribute small, invisible pieces toward a shared goal felt natural. There was no expectation of reward, no personal branding, no monetization layer attached to every action. The value was in the collective outcome, not the individual gain.

Today, even our spare resources – time, attention, compute – are framed almost exclusively through profit. If something doesn’t pay, scale, or signal status, it’s often dismissed as naïve or inefficient. In that environment, projects like Folding@home don’t disappear because they stopped mattering, but because the idea of a common, unpaid effort has quietly fallen out of fashion.

Maybe that’s the real loss.
Not idle cycles, but the assumption that doing something together, for no personal return, was once enough.

“As Tolkien wrote, it is often the small, unseen acts of ordinary people that keep the darkness at bay — and perhaps they still can.”

Ode to the 3D Printer in the Sunlit Workshop

My new Creality K2 Plus has been working overtime lately, and between the scent of PLA and the soft sound of the extruder, I found myself inspired 😛 This little poem is a love letter to that moment — where technology meets sunlight and imagination.

In the hum of gears and quiet clicks,
the printer sings — a hymn of molten dreams.
Filament threads through polished brass,
a river of corn and code intertwined.

Outside, the sun spills gold through glass,
balcony air dances with faint sweet resin.
The scent — half nature, half invention —
a whisper of fields reborn as form.

Here, man and machine conspire in light,
to summon shapes from nothing but heat and will.
Each layer, a heartbeat; each pause, a breath —
proof that creation still hums in mortal hands.

And when the print is done,
and the room falls quiet but alive,
it smells a little of corn,
and a lot like the future.

Happy printing to you all 🙂

Presonus Eris 3.5 Repair | Crackling / Popping / Hissing noises!

My barely 3-year-old Presonus Eris 3.5 monitors have started making crackling, popping, and hissing noises—depending on their mood!

Two capacitors have gone bad, and the local distributor asked for $200 for the repair, whereas a new pair nowadays costs only $100.

The distributor in a neighbouring country mentioned that there’s no service available for these monitors, claiming they are ‘commercially developed in a production line,’ although the meaning behind that statement is a bit unclear to me.

It seems they might be suggesting that these monitors are mass-produced and not designed for individual repair or servicing. I don’t see how that can be the case, but let’s move along, like obedient citizens in a world of placebo abundance 😀

If you’re facing a similar problem and have access to a soldering iron (or know someone who does :P), consider replacing the two brown capacitors with 24v 1000μF ones, or any other bulging in the cap ones that seem suspect. Good new parts are available everywhere nowadays and cost less than 50cents each…

The problematic capacitors in my case were the bulging brown ones marked with the purple arrows in the following image.

Needless to say, if you decide to tackle the project, do so at your own risk. The circuit involves a high current mains side, so take all necessary precautions to protect yourself.

Have a good one!

Calculator – Cutting large radius on a mill

Milling a large radius on a milling machine does not have to be limited by the size of the rotary table.


When tilting the head of the mill with a large cutter, be it a boring bar, fly cutter etc, the resulting cut is an ellipsis. This technique has been used for a long time by machinists before PC’s, CNC’s and other technological aids made their appearance in the industry.

The problem (or not 🙂 depending on the specifications tolerances) with the existing literature (such as the Machinery’s Handbook and others) is that the formula being used assumes that the desired width of said large radius is 0!

The following calculator averages the angle required to accommodate the width as well to provide a better approximation. By using the following calculator you can approximate a true circle radius with an accuracy of few microns.
