Jackspcs website

My URL http://www.jackspcs.com/f24.htm now goes to http://www.jackspcs.com/cgi-sys/suspendedpage.cgi . Any idea if this is temporary or is it another great information site lost?

That thread is from 2011 and I've visited jackspcs within the past month, so the latest disappearance is very recent.

Looks like the registration has lapsed. Might come back.

mrred · Dec 11, 2014

That's probably the case then. I was there a few weeks ago.

I have it archived locally if there's a particular formula or something you were looking for

Ian Grant · Dec 11, 2014

He contacted me about a year ago, it was quite a nasty bitter email and accused me of copying formulae off his website. Not something I've ever needed to do. I sent a long detailed reply pointing out my main notebook of formulae I've collected goes back to 1976 when I began working as a photo-chemist, so long before the internet and that I use primary sources, manufacturers own publications.

I am fine for the moment. This time I was looking for some samples of sodium metaborate in some of the recipes on his site. I went back to my notes.

You can access the google cached version:

http://webcache.googleusercontent.c...ackspcs.com/f24.htm+&cd=1&hl=en&ct=clnk&gl=ca

If the site dissapears entirely from Google then the Internet Archive will have it.

https://www.archive.org/

The domain name is registered until next end of next year so it is likely a problem with the web host.

That's too funny. Every formula or bits of info came from somewhere else.

The problem is that many formulae were published incorrectly in the US in the Photo Lab Index over quite a number of years and this was used as a major resource for most other US books and later internet listings containing formulae. It's not a primary source so shouldn't have been trusted, some mistakes may have been Typos others were incorrect conversions between different forms of compounds (anhydrous, crystalline, monohydrate etc) - the number of mistakes is quite large.

Probably the most accurate book of formulae now is the 3rd Edition of The Darkroom Cookbook, Steve Anchell, where all the manufacturers formulae were cross checked against Primary sources and where necessary corrected.

My comment was not on the validity of the information but on how he acted as if he owned the information he clearly got from somewhere else.

As Xmas points out you really must go back to the original source for accuracy. When in school, one of the one professor's hobby was tracing errors in text books. Often he had to go back decades to find the source of a particular error.

It is down again, Perhaps this time for good. Whoever owns the domain put up a robots.txt which prevents the website being crawled. It also mean the Wayback machine on archive.org will no longer make previous snapshots of the website available. If only someone had crawled the website before this had happened (wink).

RobC · Jan 18, 2016

somebody updated the domain details today and it looks like its paid for until 19-dec-2020.

and there are plenty search engines and maybe archive sites which ignore robots.txt but since there is server redirect to that holding page all that would be archived or indexed is the holding page.

A few years ago I contacted him suggesting one or two corrections, which he did, and he thanked me politely. Last time I looked there I still found one error but I don't remember what it was.
