Comment Ashton-Tate Framework (Score 1) 79 79

This actually happened at an important point in software history. Under founder George Tate, Ashton-Tate ("Ashton" was marketing fiction) was one of the few software companies competitive with Microsoft, although they had a different initial focus (desktop databases). They finally went head to head when Ashton-Tate bought Forefront, which was developing an integrated office suite, before Microsoft had fully committed to the concept.

There had been office suites of a sort before, generally bundles of software that didn't actually interact (the Osborn computer included bundled software worth more than the actual computer, a big selling point), but Framework was fully integrated, including its own development environment and desktop. It was essentially Windows before Windows, built on much better technology (similar to the "Lisp environment machines", but on normal hardware).

Unfortunately Tate died of a heart attack shortly after its introduction (around 1984, the Macintosh year). He had a vision for the product and was basing the company's future on it, but unfortunately everyone else had the mindset of running a database application company, and had no idea what to do with this thing. Rather than treating and promoting it as the new platform for a whole ecosystem of new software (basically an OS), they treated it as just another application, and while it had the potential to be the dominant OS before Windows was even finished, it eventually became just another forgotten Windows application.

Comment Re:Alberta not lesson enough? (Score 4, Informative) 121 121

I don't know Canadian politics, so not sure what you mean by your comment.

In the recent provincial election in Alberta (generally regarded as the core of the Conservatives (Stephen Harper's seat is in Alberta). It gets stereotyped as the Canadian version of Texas), the Progressive Conservative Party (who have held government in that province since 1971 (and before them, the also right-wing Social Credit Party held government since 1935) and before the election held 70 out of the 87 seats in the provincial legislature) were swept out by the social-democratic New Democratic Party. It was a really stunning reversal for the province that has been electing right-wing governments for longer than most have been alive to shift straight to our leftish party and, if the recent polling results are to be believed, it has given the federal NDP a serious boost and turned the upcoming federal election (which is expected to happen in October) into a three-way race.

Here's an example.

Surrette 24V, 856Ah bank for $2960. That's 20,544 watt-hours, or 10,272 at 50% DoD. That $0.276/effective watt-hour

Compared to 10,000 watt-hours out of Tesla's product, or 9,000 at 90% DoD, for $3500. That's $0.389/effective watt-hour.

The Li-ion is significantly more expensive, but as I said in my first reply, it won't take much more to drive the price of the Li-ion under that of the lead-acid. The price of Li-ion has literally halved over about the last 5 years and Tesla's gigafactory will only help that along.

Citation for what exactly? That lead-acid shouldn't generally be discharged below 50%? That a 20KW-hr nameplate lead-acid bank costs about $3500?

And how an I suggesting they fucked up by saying that a product announced last week is competitive with lead-acid? I am talking about this announcement making Li-ion competitive with lead-acid.

Sure, but the cells Tesla uses are the same ones Panasonic sells to anyone else. Panasonic may have some special sauce electrolyte that makes them better than Energizer, but that still doesn't make Tesla's anything special compared to anything else that uses Panasonic sells.

Actually, they are about the same type. Tesla's packs use a modified (PTC fuse and CID removed) version of the bog standard 18650 Li-ion cell, which is commonly used in laptop batteries.

It's the battery management system and the cooling system that would make the difference in longevity.

You will probably not be struck by lightning, but I can't guarantee that it won't happen.

Actually, when talking about airliners, getting struck by lighting is a fairly common occurrence. A typical airliner experiences a lightning strike about once a year.

It's great to be smart 'cause then you know stuff.
