Customer of 7 years wants us to sign a supplier code of conduct agreement!
Most is that we comply with all laws, and some specific laws (slavery laws, etc).
Well, I did not know they were optional, maybe they can tell us more. And if we did not comply with laws would we comply with contracts law on such an agreement we signed?
Main issue is getting *our* suppliers to agree the same, LOL, can you imagine trying to get BT to do that.
Why do people do this, it is worse than good old Y2K crap.

I can't believe someone has found the S21 message to query the fan status in a way that reports night/quiet and auto separately!
It is special, being a one byte response. First I have seen like that which actually broken my debug (probably why I never found it before).
But finally, #Faikin can tell Night/Quite from Auto, at long long last.

Anyone had any experience with MEMS microphones. I seem then as low as $0.03
I have seen some places say they have a simple output with a voltage bias already, e.g. around 0.8V.
But most things consider circuits to replace analogue microphones with capacitive coupling and a separate bias.
My thought is if the output is already DC biased, it could go directly to an ADC input on an ESP32, and need no other components to allow reading an audio input.
But data sheets seem unclear,

#TOTSCO have a form on their control pages (logged in, 2FA, https), that allows us to put in the credentials, URLs and IP addresses for our end.
But...
1. They don't allow us to edit those!
2. Even though I put them in, they ask us to send them in *plain text email* (i.e. unencrypted).
I bet they send the credentials for their side in plain text email, just waiting to see.
They are using outlook.com, does that train AI on emails? This could be fun!

That should get you a valid match confirmation. Try with surname SUNAK, and you should get a match failure.

At this stage, I don't even question Labour policies. They will have a shit load that is bad or stupid, I am sure.
All politicians are problematic. But at this stage, after so many years of so much shit, I have to say "things can only get better".
And I say that as someone that is running a company, with many staff, and many taxes to pay, knowing I have to seriously consider tax changes that Labour may bring to my personal detriment.
The country needs change, any change!

2024-05-26 09:11:12

OK I’m going to float an idea on here. It looks like we won’t be able to cancel a “broadband switch” from losing side. So won’t be able to do “anti slamming”. Shame.
But to switch using OTS you have to have a match on surname (using some fun, and vague, rules for accented characters).
So we could allow customers to set any surname on a line, and use as a sort of “password”.
After all, you can call yourself what you like, and we have to accept changes to personal information.

FFS TOTSCO.
So I have to find a matching service for a switch.
I construct the SQL query and pile on the conditions - installed and not ceased and not in the middle of a port, and the right account number and line number and so on.
I get either zero, one, or more results. If I get one, I respond with matching details.
But it not, I have to send a failure. Let's check the failure codes.

To be honest, there is no way a starship captain directs the ship using "degrees mark degrees". It would not be precise enough, for a start, and no way that it would make sense.
It would be like steering a car by constantly having to say "set course 243 degrees" and the like, rather than simply setting the sat nav.

@npub16ju…y8u7 I have the drill (dual battery makita) and the bits (metre long) because I have Welsh walls. It still takes a while!

@npub16ju…y8u7 ah, I’m more the “absolute alcohol menace” in this equation. Not had a hang over for many years (was low iron that caused it).

The general consensus is we need this to be 14 days at least. The more LNS and routers we have on line with latest code during that, the more confident we can be. The sword still hangs for now.

Yeh, it is now a proper SNMP powered uptime sign 🙂

TIL you don’t just get in to a space suit and leave your space ship, like the do in so many sci-fi, but you need to do a lot of pure oxygen first to get rid of nitrogen in your blood. It is because a space suit has to be around ⅓ atmosphere to be usable, and that means you would get the bends and very likely die if you tried it. What fun. Thanks @npub1g3j…69f8

@npub198t…hasj make sure to give those scripts one or two letter names.

This is one I don’t know…
JLC say one component, a tiny LED (1x1 m with 4 pads) has to be soldered within 24 hours of opening package, and if not (which JLC say they cannot guarantee) they have to be baked first, as susceptible to moisture.
I assumed it was the pads and would lead to a dry joint.
JLC are saying it’s not, and some aspect of the component itself! Surely that makes no sense as reflow would bake it anyway and moisture is a risk after soldering, if so.
Are they bullshitting me?

@npub198t…hasj Interesting. Legally, what stops a club forming of men, and any man can join, well, anyone can join, but if a women joins, all other members leave and make a new club.
(same logic for being white, or some other criteria).

This heading really pisses me off.
“We value your privacy”
No! Like fuck you do!!! If you did there would be no pop up and no “partners” at all. It’s lie.
Or perhaps “yes” we “value” your [lack of] privacy in £££. So fucking say that.

@npub16ju…y8u7 The heavy duty double sleeved may be good if they do that not gel filled, if it could get any damage, otherwise simple UV stable sleeved stuff I guess.
But yes, fibre if you can...
In my case it is around the outside of the house and an outbuilding and some PoE involved, hence not fibre.

@npub16ju…y8u7 The main thing with external cable I find is that you can get with and without gel filling. Either way you need UVC stable sleeve, but the heavy duty gel filled stuff is evil* to work with. I suspect only needed if you are running under water. I have some running inside a drain pipe to get from roof to ground level.
*protective gloves and a lot of patience.
Looks like Kenable do the later, for burying.

@npub19lt…qfjk What would be nice is a generic way for me to provide a set of data, including avatar, and possibly contact details, and so on, that I want to make available to some parties, and a means that they can update.
That way I would never have to tell someone a new avatar, or phone number, or address, or whatever.
