The SETI@Home screensaver [0] (the predecessor to BOINC) was the peak of nerd-cool when I was 11 or 12 years old. I had no idea what any of the graphs meant, and still don't, but I knew that I could help find _aliens_, and look like a hacker doing it [0] https://en.wikipedia.org/wiki/SETI@home?useskin=vector#/medi...

When energy was cheap...

I understand that; I didn't express my question clearly: Given the electricity used, how efficient are (Boinc + my desktop) at generating heat? For example, is it equally efficient to use Boinc + Desktop to warm my office as it is to use a space heater, or electrical radiated heat?

A computer consuming 500 watts of power and an electric heater consuming 500 watts of power are equivalent. Therefore, I think it's perfectly reasonable to run BOINC to warm your office.

If the goal is heating, you'd be better off with a heat pump, to get 300% or more of the input energy back as heat. Doesn't do computation as a side effect though.

Distributive DCP lets you compute other people's distributed research/workloads and get paid for it (no crypto involved). Compute workloads get run in secure js/wasm compute nodes (which could be your browser, or a screensaver, etc). For instance, my friend built a Blender cycles renderer using it It's cool tech continuing the awesome legacy of BOINC! I work at Distributive, AMA if you're curious

A commercial version of Boinc - nothing wrong with that. However, the website give no indication of price, except a claim that it is less expensive then the cloud.

More important for this discussion: there is zero indication of what people earn, in return for offering their computing power. Which probably means that it isn't much - better to mine some random coin?

Just wait until you hear about Bitcoin

Just wait until you hear about most ecommerce platforms doing `SELECT * FROM` just to display 2 columns.

Just wait till you hear about the developers out there doing `select* from` and then using reduce inside their api server to sum up the values of a column.

The situation is a bit different today. Back when Bionic and Set@home were more common the CPUs used more or less the same power whether they were idle or in full use. Nowadays however running something like this will run up considerable extra power usage and is no longer "free".

Citation needed. My understanding is that the only computers that were built this way were super computers using ecl logic. One of the key features of cmos logic was that is was much lower power when nothing was being done. Now admittedly DOS and I think windows95 liked to use busy waits and this does not help matters. But I still think the system got hotter under heavy load. Now I wish I still had an old pentium box around so I could measure power draw with dos and prime95.

If you're this salty about SETI being a waste Of computing cycles, wait till you learn about bitcoin.

It's weird people keep comparing this to Bitcoin. That's like "Oh our best & brightest sunk years and billions into a known-bad type of Alzheimers research? Wait till you hear about Pets.com"

"known-bad" ... defined by you? Cause if the best & brightest did it (in this case SETI@Home) it seems they disagree with that categorization.

Well, one used maybe tens or hundreds of megawatt hours over the course of a year, while the other uses tens or hundreds of terawatt hours per year.

One was a launching platform for dozens of scientific and other large scale volunteer computing projects, and the other's value is entirely based in speculation.

Folding@Home predates the ML approaches to protein folding. Just because it has been eclipsed now doesn’t mean it wasn’t worthwhile.

Well, it predates the deep-learning ML approaches to protein folding like Alphafold. But people have been applying ML methods to protein folding for decades -- that has long been the two camps in the protein-folding bioinformatics world -- whether the best way to get structures was to simulate what the protein was actually doing or if there was a computational shortcut.

The goal of protein folding simulations like Folding@Home is not to predict 3D structures - it's to understand how folding actually works, and why it sometimes doesn't work. When FAH came out it was already very obvious that there were good computational shortcuts to predicting the end state (the Rosetta approach), but those don't tell you very much about the physical process. Different questions call for different approaches.
