The text says “a current with a potential of up to 1 volt.” The key word is potential, i.e. electrical potential whose SI unit is the volt. That must be the amount of potential that this particular chemical reaction can create. Since the current probably depends on the amounts of the chemicals involved, the article doesn’t state that.

The text now says that, yes, but the original did not according to archive.org.

It's an elegant fix that adds nothing.

March 20, 1996. Before that I worked on so many different computers that I didn't manage to keep a continuous archive. Early on, my files would have been on punched cards, then 9-track tape, then 8" floppies, etc. I do have some usenet postings from 1981 that are still viewable. The oldest is here: https://groups.google.com/g/fa.unix-wizards/c/o2fAr_mGPa8/m/... At least I no longer feel I'm "naive in terms of UNIX" as I stated in my posting :)

You probably had a few audio cassettes with data squirts too. I find it intriguing that few people alive today have ever used diskettes, and of those far fewer remember a time when there were crazy-many diskette formats, even on the same medium. Hard sector vs. soft sector. When do you tape over the write protect notch, when you want to write or when you want to protect?

I was always an island computer geek isolated from the mainland (except BBS long di$tance) so we had to start our own commercial ISP in the mid 90s to bring it. My first USENET was a post to alt.flame in September 1994: "Bigfoot! Watch out, boy! They are looking for you in Des Moines. Time to move on. Warning: the Kansas city account is being monitored by professors from the UT Anthropology Dept. Don't use it. Use the Finnish anonymous server through East coast account number 3 to forward new address. Courage, beast."

So there was an MIT Center for Cognitive Science! Did you ever find intelligent life on Earth?

I'm a huge fan of https://nextdns.io which works on iOS.

This sounds similar to Radiant Earth https://www.radiant.earth/ They are also spearheading the Cloud Optimized GeoTIFF project http://www.cogeo.org/ and the SpatioTemporal Asset Catalog spec https://github.com/radiantearth/stac-spec.

I found v3 on the App Store by going to the Sketch 2 page and noticed "More by Bohemian Coding" on the right side had a link to the Sketch 3 app store page.

National Security Agency, not Administration ;)

It went to the 'allmit' list (http://mailman.mit.edu/mailman/listinfo/allmit) which goes to "all current students (including incoming freshman and graduate students, special and cross-registered students) and all employees listed in the MIT directory or with SAP status=active" which is upwards of 22,000 people.

Right and evidently whomever shared this did not want the other 21,999 people seeing that they had posted it to their blog. So they shared it anonymously.

App Inventor is here now: http://www.appinventor.mit.edu/

I just got this on Fidelity:

  Attention: FB order execution slowness Certain marketplaces are experiencing slowness resulting in delays in execution for Facebook orders. Industry technology teams outside of Fidelity are working to correct the problem. This slowness is being experienced by other online brokers as well, not just Fidelity. This has been reported as a market-wide issue. We do not yet know when the problem will be resolved. We appreciate your patience.

The fine for jaywalking in Massachusetts is one dollar. It's unheard of here to be stopped for crossing the street anywhere. When I first arrived in Boston, years ago, I was waiting for the light with a bunch of other pedestrians when a cop came along and said, "what are you waiting for? this is Boston" and crossed the street with the rest of us behind him.
