Yep. It's something I had in onenote I was going to reply with the next time someone asks me that question for ref which happens at least once a week. I didn't type all that now :)

We could just start a thread called "BD139 and Cerebus bitch about software." and then we could just post links to the relevant messages rather than reposting the same rants over and over again.  :)

Perhaps, but how much would you pay for us not to post a video entitled "BD139 and Cerebus get drunk, strip, and practice Country Folk Dancing."?

[Fx: Shouts aside] Hey, BD, I think I've got our retirement/TEA  giga-fund sorted.
How much would YOU pay me not to post video of a dwagon pole-dancing...?

That old "If you're not doing anything wrong you should have nothing to hide" line is nothing more than minionspeak designed to put you on the defensive when you're discussing the core rights to privacy and those outlined in the 5th Amendment. It is directly contrary to the core principle of "Innocent til Proven Guilty." FUCK THAT HARRY HIGH SCHOOL BULLSHIT. You are a citizen, you have the right to a certain level of privacy. PERIOD. Government agencies & Corporate entities given special privilege under the provision that they will not work against the good of the people at large do NOT have that right. PERIOD. And they certainly do NOT have the right to violate that core Right to Privacy just to sell you fucking shampoo.[/color]  :palm: 


It is simpler than that, and applies to all forms of government and authority.

That's why this quote has been remembered and repeated for centuries: “Give me six lines written by the most honorable of men, and I will find an excuse in them to hang him.” Cardinal Richelieu

I'm miffed.

I've been looking at my Keithley 230 programmable voltage source, and it is almost very good. It generates the right voltages, but not completely reliably.

If I select 10.000V output, and the output is measured at, say, 10.001V then I'm happy.

If I then drop it a couple of cm onto the bench, the voltage shifts out of spec, e.g. from 10.000V to 10.012V. Possibilities:
  • the wretched Bourns 3386 single-turn trimpots are shifting. But looking at the schematic, a quick calculation indicates that it would have to be a relatively large shift
  • some socketed metal film resistors in the current limiting part of the output driver
  • some Coto relays in the same circuit
  • another relay which operates to disconnect the output when there is no power
  • a switch for internal or external voltage sensing
  • the socketed DAC08 inckuding reference
Reseating the obvious components with Deoxit D5 does not improve matters.

If I then change the output from 10.000 (i.e. 10.008V) to 100.00V and back again, the output voltage returns to almost 10.001V. Now there's a range change there, but what is causing the "hysteresis" in output value?

I suppose I'll have to stop now and find some precious treasures to flog on fleabay; thanks bd for pointing out the £1 fees.

Thank mansaxel, bd, horse, Cerebus and the others for the DNS discussion. I really enjoing it, sorry for the others who were annoied by that.

Temped to open a new thread just about that in the "Computing" section, this is so much value it can't be stay hidden in the TEA, or yes it must stay here  :popcorn:
I don't think many were annoyed by it at all, but I do think many, and I'm one who wonders why everyone needs this level of secrecy, it's almost as if there was some deep dark military secretive plot your all involved in. I can't for a single second believe that anyone is involved in anything even sightly illegal, therefore have nothing to hide,  just curious as to the reasons people seem to knocking themselves out, and costing themselves extra expense, doing what is already freely available.  :-// :-//

If, for example, you live in China, the answer to this question is pretty clear: your location, interaction with others, purchases, online posts, internet traffic are all tracked and your freedom, ability to earn a living, etc are dependent on how that collection of information is evaluated by an opaque police state.

If you believe that the facts about your life - where you work, what you buy, how much money you make, what websites you visit, your hobbies, who you associate with - are yours to share or not as you choose, then the development of a surveillance-based consumer culture is not something you should be thrilled with.  If you have some sense of history, that kind of culture should scare the crap out of you because the leap from "your facts for a free email account" to a world in which the government is using your data to decide whether or not you need to be punished is not that large.

Something else TEA related for a change ;), a bit more information on HP serial number prefixes for the older HP/Harrison power supplies with a three part serial number tag;


First part is the model number, in case it got missed on the front panel.  :-DD
Second part the serial number prefix (number-letter) denotes the date of a significant design change (number designates the year, letter A to L designates the month Jan to Dec).
And the third part is the serial number.

Hope this helps anyone wondering about those serial numbers tags with a single number/letter prefix, I found the description in the HP 6516A manual.

The ship didn't sink. The boatload of capacitors finally arrived. Started with a simple one. Going under the knife is a Fluke 1912A Frequency Counter. Only 2 caps.

Before.



After.



The patient survived the ordeal.  :P  (And no, leaving the tants alone for now. Never had an issue with them in Flukes)

Oooh, dwagon household is in disarray and poppa dwagon is not happy.  :popcorn:

Our middle one was a shocker every weekend and we'd never see him from Friday morning till Sunday afternoon and he was still pissed  ::) but he never missed a days work ever as a result of his wayward weekends. One Sun afternoon when he staggered home with skinned knuckles he sold the line to his mom that he'd fallen over and skinned them.  :-DD
She swallowed it hook line and sinker  ::) and I gave him a wink as he slinked off to bed to sleep the weekend off and be ready for work the following morning.  :)
Now in his early 30's and a solid as a rock sorta guy.

Lies, well some are worse than others.  ;)

Welcome to parenthood !

A good few years earlier the lad above swore and cursed me and promptly slunk off to his bedroom but didn't factor in that he'd waaaay overstepped decency and the ol' fella was in no way gunna stand for that but figured it out soon after when he went flying through the air to land gently on his bed.
He had a new found respect for pop's power and we've had a great relationship from that day on.

Hahaha that is pretty mild. I’ve seen the really dark stuff  :-DD

Edit: it has been a mission to replace goatse with something even more horrifying for about 20 years now since someone got me on slashdot once. I haven’t succeeded but I’ve seen all the lowest points of human existence and the insides of some of the darkest and most fucked up minds out there on the journey. There is much more to come yet as well  :-DD

On topic have three things newly added to watch list  :-+

Yeah; arse-whoopin' doesn't work on this one; strengthens the resolve. Just like his daddy. ;) No, I've taken to taking away the things he really cares about for this one... ALL GAMES AND GAME-RELATED ACTIVITIES for 2 weeks. No Pokemon. No video games. No related videos, no sorting and stacking and obsessing over his cards, and he can only use his tablet for reading or educational games.

Woops... scratch that... JUST NOW caught him playing a racing game.

Now he can read dead-tree format or play with his sister. Period.  ::)

Next level will have to be a whoopin' and adding on another week I guess...  |O

Well, what makes that particular example perfect is how it sums up that whole phenomenon for what it really is: childish masturbation. goatse was just a well-executed global troll... it made its mark on our collective memespace, and we survived. Kermit goatse was similarly the perfect answer to that.  ;)
