Re: Foresight

Just look how long older appliances lasted, compared to modern ones.

cars... older ones just run and run and run... in an accident, you can actually buff out the damage... with modern cars, there's no amount of buffing damage out and they seem to be engineered to be thrown away after 5 years... it really is a sad state of affairs...

Re: Cool Running

The trick worked on drives in the past because back then the bearings did wear out and increased tolerances together with less than stellar head positioning would lead to read/write failures.

not only that but there was also the protective coating on the platters that, in some cases, would soften from the heat of operation... when the drives spun down the heads would settle into the now soft coating... when the drive cooled off, those head were effectively cemented to the platters...

when the drive was powered back up, the heads would prevent the platters from spinning... this is where the quick spinning or light thumping would come in handy to pop the heads loose and let the drive platters spin properly... freezing the drive would, in many cases, allow the coating to shrink away from the heads so the platters weren't held captive when power was applied...

yes, sometimes a head might get torn off the arm it was mounted to... i'm sitting here looking at a clock made from an old ST-125 that had this happen... luckily it was the last head in the count that came off... luckily? yeah, because i low leveled the drive and told it it had one less head... yeah, that reduced the available storage space and the data was lost but it worked well enough for the tasks it had to do... that drive ran for another 5 years or so before being replaced by a larger drive and one that didn't have the sticktion problem...

since it was already damaged, i removed the cover to get at the insides... the bottom side of the bottom platter had a nice clean circle scrapped into it where the head had gouged out the material... i powered the drive and used a screwdriver to carefully scrap another circle for added decoration... then i removed the platter motor and replaced it with a clock work, figured out how to mount that one platter, and applied a ring of numbers along with some clock hands... the cover was replaced with a custom hand-cut plexiglass cover and boom! one hard drive clock was born :)

Re: Lost dog pictures

Aren't hard drives sealed

no, they weren't... they had small ventilation holes to keep the air pressure equalized...

if so how could there be any moisture inside to condense?

moisture on the outside can also cause damage... especially when it forms across two or more non-insulated wire traces or through holes on the board...

on a similar note, i was called out to a rock quarry back in the '00s to fix a system that was "acting weird"... getting to the site was a bit of a wonk because the dirt roads were eaten away by all the large heavy trucks and several weeks of rain... i ended up parking my car at the entrance and riding in in one of the dump trucks because the road in was so bad... a few of those holes would have swallowed my car quite easily...

upon opening the system to take a look at the insides, we were greeted with a layer of silica dust about .25 inches thick (about 6mm) completely blanketing the motherboard and all the surfaces inside the machine... dry silica dust is generally not much of a problem other than when it builds up enough to slow or stop the fans... moist silica dust, on the other hand... well... electronics and moisture don't mix too well... especially not when the electronics are old original IBM PCAT systems that are not cleaned on a regular schedule... they did at least have a "keyboard condom" in place because they had had to replace the keyboard several times from all the dust...

yeah, they purchased a new(er) system and spent i don't know how much on fitting a decent air filtration system along with scheduling regular cleaning and removal of the captured dust...

Re: Seems ok

You're absolutely right. He should have done it as a favour, and then noted he was a bit short of cash at the moment

this might have been fine, but...

and could you lend me £100 to see me through till payday.

this, on the other hand, indicates he would pay the £100 back on or about payday... terms like "lend" and "borrow" mean "pay back" which, in this case, would mean he did the task for free... now, if you had said "and could you let me have £100 to see me through till payday." i would agree with you... terminology is important... very important...

Re: Don't forget the other bugs introduced by copy-n-paste software

There are no serious integrity checks run on newly-acquired libraries or on code cruft. "It's been working before, it should work now.)[sic]

you know this is part of the problem, too, right? everyone checks for their "desired working output" but who in their right mind bothers to check for "undesired output"? i mean, this is what unit testing was developed for but who actually uses that any more? "it is too old!" "it is too '90s" whaaawhaaawhaaa

this is in the same vein of not bothering to use stack or heap checking or even bothering to check that a buffer is large enough to hold what you are trying to stuff into it... this is the kind of c4rp that has allowed buffer overruns and so many of today's infestation techniques to proliferate...

Re: Clock embuggerance day

After that your motherboard clock will remain persistently UTC, and the operating system will display the correct time from that based on the time zone that you tell it you are in.

this is how it should be done, yes... then one simply has to remember that the BIOS clock is UTC if/when they have to change the battery or the BIOS clock loses its time for some reason... aside from that, be sure to select the proper timezone representation and bob's your uncle... most of the time...

Re: Laying on of hands

have you forgotten the four basic unspoken rules?

- programmers only look at and think about code...

- technicians only look at and think about hardware...

- if hardware is the problem, don't expect a programmer to fix it unless you are looking for them to (blindly) (try to) code around the problematic hardware...

- if a program is the problem, don't expect a technician to fix it unless you are looking for them to (blindly) (try to) add faster CPU/GPU, more memory, and/or more storage...

there are more but these are the main ones that form the base everything else is built on...

Re: Melting

The replacement ECU was hastily modified by removing the battery and reconnecting it remotely through two fly leads.(just in case!)

we used to do similar in our computer shop... desolder the onboard battery and solder in a replacement AA battery pack... mount the pack to the wall of the case with double-sided tape... some of these replacement packs conveniently came with plugs on the wires that plugged onto the header on the board... otherwise we just soldered the wires to the same places where the battery was soldered...

the main idea was that we 1) removed a possible corrosion problem from the board, 2) made it easy for the user to replace the batteries when needed, and 3) alleviated these types of board-level repairs in the shop... #3 especially because there are inordinate numbers of college trained electronics techs that couldn't solder their way out of a wet tissue...

i can't even begin to count the numbers of boards we had to replace the traces on because of bad batteries leaking and damaging the boards... that was if we could even get to all the damaged traces to replace them... the ones with through-the-board connections were especially painful to deal with when those were also damaged by the leaked corrosives...

Everybody's time is precious, pal: Sometimes it isn't only the terminals that are dumb

dumb terminal with modem on top???

when i read the phrase "dumb terminal" i think of Wyse 60 and similar... what i'm recalling is fairly thin devices like today's flat screens... i have a hard time picturing how a modem (eg: USR Courier) that's roughly 8" x 5" (203mm x 127mm) and maybe 1" (25mm) thick is sitting on top of a terminal housing that is only a few inches thick... these things i'm remembering from the late '80s were not CRTs but we did have a bunch of those, too...

while trying to be fairly accurate with my measurements, i went looking for pictures and dimensions of these terminal devices my mind keeps picturing... weird that i cannot find any that look like those i remember... thin clients are close but they have too many brains in them... the ones we used required at least a two wire (TX/RX) serial connection and had no brains in them at all... green or amber monochrome and no graphics capabilities at all... we used them with PCMOS, a multiuser multitasking disk operating system, running several database applications on FoxBase (before m$ acquired it)... the "servers" we used at the time were maxed out 286, 386 or early 486 systems generally loaded with several Digiboard serial cards to provide 16+ terminal connections and as much memory as the system could handle... i won't mention all the fun inserting all the memory chips into the EMS/XMS memory boards we used to max the systems' memory out...

Re: Fake accounts? You sure?

I would love to have a simple way of populating Chrome's password store with fake logins (real login in password manager), as I suspect that some webpage malware has been able to access the password store - given the old passwords that I'm threatened with.

why use malware to access and decrypt some local password storage when one only need to use an "invisible" iframe and embed a ftp link which causes the browser to use the user's configured name and password? that's an old method, though, and it doesn't really work any more with modern browsers... it wasn't quite that easy, either, but it is the gist of the method that i'm conveying without going into too much detail...
