It's probably enough to just listen and let him talk.

Saskia:
fully aware of it, however I do not have the strength to listen to him for hours. Unfortunately.
He needs *help* and to provide this is beyond my current capabilities.
Unfortunately.
He is 350 km away. he is suffering from burn out, depression, huge stress due to his mother slowly fading away. It is beyond my capabilities to do more for him than listen to him for 3 - 5 hours/week and try to help him out. He would need someone there full time to take the load of home care off his shoulders, someone out there looking after his mental and physical health, someone to take care of his family house which started to rot away. If I had been a millionaire I would have tried to help with the daycare stuff and the house. But I am not, and we have more than enough on our plate already. I am sorry, but there is only so much I can do.

You can forgive the Poms as they've yet not learnt how to properly chill beer !

--- End quote ---

Oh, we've tried. We found that it is impossible to do.

Chilling gnat's piss is easy, however.

Gnat's piss examples include Coors and anything that needs to be advertised by a "muscle man" (Which may or may not also be Coors; nobody cares)

--- End quote ---
Maybe its due to the higher alcohol content of our beers, gnats piss is by default, largely just coloured water  :P :-DD

--- End quote ---

I don't think so. Some gnat's piss has standard alcohol content, and some beer has a low alcoholic content - and is quite pleasant in summer :)


--- Quote ---What ever, consuming quantities of said amber nectar over here in the UK is not to be advised during this heat as the alcohol actually dehydrates you so the experts warn...hang on, isn't that confirming the sentence above has some truth to it  :-// :-DD

--- End quote ---

Beer will dehydrate you less than, say, a G&T. If 10mg of alcohol "dehydrates" you by encouraging urination, then with a beer you will get more water with that 10mg to "rehydrate" you.

--- End quote ---

The whole thing about beer dehydrating you is an old wives' tale. Each gram of alcohol consumed causes a net loss of around 10 ml of water (generally accepted and easy to remember figure). So a pint (568 ml) of 4% abv beer contains 22.7 ml of alcohol, giving 17.9 g of alcohol. This will cause the loss of 180ml of water, but the pint of beer will have supplied about 540 ml of water (with perhaps a small fudge factor for dissolved solids), leaving a net result of at 360 ml of additional hydration.

The G&T case is actually marginal as well: 25 ml shot of 40% gin - ~8gm alcohol - net fluid loss (80 - 15) = 65 ml to be made up with tonic water and ice. So as long as your G&T is 1:2.6 gin and tonic respectively you're not going to suffer dehydration, with any excess tonic over the 2.6 contributing to hydration, but by the time you get any significant hydration from drinking it you're going to be pissed as an admiral.

I don't think this is how it works. AFAIK the water passes through your system quite quickly, while the alcohol takes time to break down. Also I believe the headache associated with hangovers is caused by the buildup of acetaldehyde, which needs more water to help flush it from the system? After a quick read of this I'm not really much the wiser; looks like the answer is "it's complicated".

The fact remains however, that if I had enough to drink that I got wobbly the night before, the morning after I'll have a mouth drier than a sachet of desiccant beads in the Atacama desert.

--- End quote ---

That is how it works. Alcohol is a diuretic, but a mild one (e.g. https://pubmed.ncbi.nlm.nih.gov/10204649/). What rate you balance water at (homeostasis) is totally devolved from alcohol metabolism.

Ethyl alcohol is quickly metabolised in the liver to acetaldehyde via Alcohol Dehydrogenase (ADH). Acetaldehyde doesn't give you a hangover, it's quickly metabolised to acetate (in the form of AcetylCoA), by Aldehyde Dehydrogenase (unless you're deficient in aldehyde dehydrogenase like some asian populations are). Acetaldehyde is responsible for the increased superficial blood flow that makes you feel warm and your face redden when you've been drinking. If you're not 'glowing' then the acetaldehyde has fallen below physiologically significant levels. Acetate enters normal metabolic pathways as fuel (oxidative phosphorylation, Kreb's cycle) bound to Coenzyme A, so that too gets used up quickly. A typical ethanol metabolism rate for a healthy 70kg male is about 10g/hr, the availability of ADH and ALDH being the limiting factor and both can be induced via the classic operon route, which is why regular drinkers get drunk less easily.

Urination (and thus the use of water for urination) takes no significant part of ridding the body of either ethanol or acetaldehyde, any excretion via that route is purely incidental (0.7 - 1.5% of alcohol consumed is excreted unchanged in the urine). The kidneys concentrate the things excreted via that route, thus if they were involved in getting rid of alcohol you'd drink beer and piss whiskey. We know you don't, not from any great scientific investigation, but simply because if you did it would have been discovered *ahem* naturally a very, very long time ago. Thus there is no use of water to 'flush out' alcohol or its metabolites.

Most of the hangover symptoms are caused by other alcohols that don't neatly pass down the well evolved EtOH->MeCHO->Acetate pathway. Those alcohols produce intermediate products that don't happily trip through the pathway - the classic being Methyl Alcohol, which is initially processed by Alcohol Dehydrogenase but instead of acetaldehyde produces formaldehyde which does direct damage by binding to everything in sight before Aldehyde Dehydrogenase can get anywhere near it.

Just because you wake up with a hangover and a dry mouth doesn't mean that you're dehydrated. There are plenty of things that can leave you with a dry mouth other than dehydration, snoring like a bull elephant for instance. In fact it's quite dangerous to assume that someone who can produce enough saliva to comfortably wet their mouth is adequately hydrated. Next time you have a hangover pinch the skin on the back of your hand. If it snaps back (speed depending on skin elasticity and hence age) you're not dehydrated. If it 'tents' and stays in the pinched shape, or takes significantly longer to snap back compared to what's normal for you, then you are dehydrated.

In the interests of science you should now go and get absolutely plastered, test your hydration and report back.

ANother DIP8 to pick your brain, if you know what it is / datasheet :

It's marked " C81DC ".

Again somehow Aliexpress has one for sale :

https://es.aliexpress.com/item/1005001738808933.html

But the ad doesn't say what it is, so not much help.

All Goolge can tell me is that most likely, this chip is made by Toshiba, and maybe it's an analog / Linear IC, and maybe just maybe, it could have something to do with fast signals like video signals, most likely in consumer gear I imagine...
Also possible, not sure, that this C81DC a code and not the actual part number, which does not help.

The winner gets a bucket load of ice cubes.

Thanks. So if... if this ebay ad is not full of shite, then it's a little serial EEPROM.... now need the datasheet for it so I can use it.

What ? You still have not found it ? I am waiting...  >:D

--- End quote ---

Sorry the delay, had to visit a food store, and collect a parcel.
(old days were not better, post was already closed a moment after lunch)

Google "i2c c81dc" and there it is.
Samsung TV and C81DC, 1028x8Bit, 8P, 100mS, 5V, PLASTIC, 10uA, CMOS IC-EEPROM.

Seems to be regular 24C something memory bnut numbering is a bit odd.

E,
I already corrected that nut.

Saskia:
I fucking hate Microsoft.
Nuke them from orbit.
