Stuff that occurs to me

All of my 'how to' posts are tagged here. The most popular posts are about blocking and private accounts on Twitter, also the science communication jobs list. None of the science or medical information I might post to this blog should be taken as medical advice (I'm not medically trained).

Think of this blog as a sort of nursery for my half-baked ideas hence 'stuff that occurs to me'.

Saved by a fax machine: the most ridiculous error I ever made with a computer

tl;dr version: I stuffed up a computer by mucking about with the regedit or .bat file and it wouldn't start. This was in the early 90s and the only way the company could help was by faxing me instructions to type into a new text file to save on a floppy disk from which I could then boot up. 
Fortunately it worked :)

In the early 1990s I used a computer to control a pump that gently delivered solvents, at a defined rate, into a long thin chromatography column, for lipid chemistry purposes. The column contained a substance which slowed down the compounds in my samples as they passed through, based on a relative attraction to either the solvent or the retarding material (also a little bit based on their size and other physico-chemical properties). This resulted in a complex mixture going in one end and individual components coming out ('eluting') from the other end, for me to collect and see 'how much'. The computer provided a reading of the output based on the refractive index of the eluted solution (eluent), transferring this to an on-screen graph.

At some point something went a bit wrong and my boss suggested I be a bit braver than I had been about fixing it myself so I read the manual and asked people in the computer department. I learned that I had to do something to the registry file, which underpinned the whole functioning. So I did.

After I'd done what I thought I was supposed to the computer wouldn't switch on (well it wouldn't boot up and I couldn't interact with it). My boss agreed that I probably should have called in an expert and I was a bit worried that I'd seriously stuffed up the computer and rang the manufacturer to ask for help. As it was such a long time ago, and as I resolved never to do it again, I've no record of exactly what I did or to which file but I remember 'regedit' and .bat files being involved.

The company said that I'd need to boot the computer from a disk (which I didn't have) so they said they'd fax me a set of instructions - I don't think they had email at that time, though I'm fairly sure that I did (was working in a university), so a fax it was. The fax turned up and the program was pretty short - I went to another computer, opened up a .txt file in notepad, typed in the code and saved it with the appropriate file ending onto a floppy disk. It worked perfectly ;)

I am just recording this small curiosity in the history of me killing computers...

Comment policy: I enthusiastically welcome corrections and I entertain polite disagreement ;) Because of the nature of this blog it attracts a LOT - 5 a day at the moment - of spam comments (I write about spam practices,misleading marketing and unevidenced quackery) and so I'm more likely to post a pasted version of your comment, removing any hyperlinks.

Comments written in ALL CAPS LOCK will be deleted and I won't publish any pro-homeopathy comments, that ship has sailed I'm afraid (it's nonsense).
