A paper on Secure E-voting Using Homomorphic Technology.

I just have to say that must be the shittiest font I’ve ever seen used for academic research. I might still read it since it’s only a few pages!

Thanks for the feedback. I figure it can’t hurt to experiment. Every time the machine starts coughing and sputtering, I’ll make a couple passes with used descaling solution. Guess I should keep track of how many iterations I use it. When it fails to work, I’ll make a fresh batch. I might experiment with doing the 1st pass with used solution and a 2nd pass with new (or newer) solution.

BTW, that Cloudflare link you gave is a booby-trap of dark patterns. It gave a blocking cookie popup with no “reject all” option to Tor Browser and an endless list of cookie switches to toggle, so I tried lynx. It gave a 403 claiming “enable javascript and cookies to continue” to Lynx. Then I loaded the archive version in Firefox with js and animations both disabled, and I could finally read the text (very useful and far deeper than I can comprehend). But then an animation at the bottom played anyway. I had to disable still images to stop the animation (guessing the ad is an animated GIF).

What a disasterous display of web enshitification.. anyway, I hope this helps someone.

One of the interesting points that was made is different machines have different components, so it’s best to use the manufacturer recommended descaling solution. Which I assume would also be commercially biased. I hope one day the #rightToRepair will require a disclosure of the materials in the machine and chemical requirements (as opposed to brand requirements).

That page inspired me to create a new community: “Asshole Design: Web Edition” :).

I had an extremely slow kitchen drain recently where a liter of water took a couple hours to drain. Every week I poured boiling water into the drain pipe that came out of the wall (bypassing the trap), waited ~30-60 min for the temp to drop a bit before giving a dose of enzyme-based cleaner so the enzymes had a warm start and could chow down on whatever was in there. After a month or so there was no noticeable progress. Snaked it. The snake made it all the way to the main pipe but strangely did not clear it. So I poured in ½ liter of sulfuric acid and let that sit for hours. Still not clear. Then I plunged the line with the acid in it using the kind of plunger that attached directly to the pipe. That cleared it. I have no idea what the clog was.

Now I run the dishwasher on the highest temp as a preventative measure. The lowest temp (50°C) is good enough for the dishes but I figure the highest temp (70°C) will help maintain my crappy kitchen drain pipes. It’s unclear to me if I’m wasting energy or being sensible. IIUC, the 70°C temp setting is for pans (which the dishwasher maker expects to be greasy). The clog that I cleared was from the previous tenant (a young student, probably careless and not knowledgeable about drains). The only grease or oil I put down the drain is residual after a bulk of it goes to the compost.

You can also market that soap as arm pit & groin soap to capture a much bigger market since everyone has arm pits and groins but not everyone is a mechanic.

I’ve heard that argued both ways. Some people claim it cleans the lines. But my instincts are to agree with you. If the coffee ground gets greasy that would seem to give it a chance to stick in the pipe or simply stick to existing grease. OTOH, grease in the pipes can be melted by pouring boiling water down.

Since coffee is great for compost, the bulk of my coffee goes to the plants or to the compost. But I’m still keen to clean with it. Not much is needed for cleaning. 2 pinches is enough for one arm pit, or two hands. Some coffee grounds stick to my filter after shaking the bulk of it into a plant so I end up rinsing those down the drain as well.
