... fond old memories of replacing a dud 4K DRAM on a Vax 11/780, all on my own (the company I was working for was too cheap to pay for a DEC service contract).

... fond old memories of replacing a dud 4K DRAM on a Vax 11/780, all on my own (the company I was working for was too cheap to pay for a DEC service contract).
Unfond, more recent memories of being asked by the Dell support tech to remove all the DIMMs in the server and start putting them back, one by one.
48 DIMMs. 15 minute BIOS boot time. Didn't even bother doing the math.
It was a better use of our time and money to mention "contractual four hour response time" and "We're about to send email to our corporate lawyer, do you want to reconsider your support response?"
- udev 4y agoThe 48 DIMMs problem is not so bad... Remember those problems where you are given n gold coins (among which one is fake) and a balance, and the task is to find the minimal number of weighting operations to identify the fake coin. So, you go binary search looking for the borked DIMM, load 24 DIMMs see if it crashes, if no crash -> the borked DIMM is in the other pile, rinse and repeat...
