- Comment on Why do people care so much that their friend or family member’s partner is attractive and not just loving? 7 hours ago:
I’m pretty sure that it boils down to successful procreation genetics. As in, the more attractive you are the bigger the selection of mates you have access to. It’s been happening for as long as life has existed here.
No doubt this has across history been heavily distorted by culture, art and religion and in more recent times by fashion, marketing, advertising and media.

It might be an idea to raise the issue with your member society directly. Their “official” contact details, and that of every society is here:

So, your eyeballs already do this … that is, convert radio frequencies into electricity.

- Comment on Could you use a stationary array of antennas to form an image? 2 weeks ago:
That you posted in this community means that I am going to assume that you understand that light and radio are the same thing. This means that anything that can “detect” light is essentially an antenna, for that (range of) frequency(ies). The Charge Coupled Device sensors or CCD sensors are in common use in digital imaging, it’s an integrated circuit that can detect light. Or said differently, a CCD can detect radio waves at light frequencies.
In other words, a CCD chip is an array of antennas, that do what you describe.
I’m not sure what a densly packed array of nanoscopic antennas brings that isn’t already solved with a CCD.
CCD’s are also used outside the visible spectrum in all manner of places.

Here’s a question.
How is a digital cumshot image of a person worse than say a kitten being tortured, or a war being fought?

I’m guessing that you’d need a big backyard for either … so I’m out.

I’m not familiar with how many telephones in Spain are landlines, but looking at Australia, where I am, the majority of connections don’t have an SLA battery, made even more power dependent because we have been rolling out fibre optic cable everywhere and the copper wire in the ground has been disconnected, preventing telephone exchanges from powering much of anything anymore.
The idea that generators will keep the essentials running is incomplete if not outright incorrect. Most of these systems have never been actually tested with an actual outage, look at Heathrow airport for a recent example.
At best a generator will run for up to 12 hours, and only if you have multiple generators and the fuel to run them will you have much in the way of energy security.
Of course if you’re already running on a generator then the picture is different, but even then, in the case of a country wide power outage, getting fuel for longer periods of time is going to be a challenge.
- Comment on Does humanism lead to tolerance paradox? 4 weeks ago:
Do you mean this: en.m.wikipedia.org/wiki/Paradox_of_tolerance
The paradox of tolerance is a philosophical concept suggesting that if a society extends tolerance to those who are intolerant, it risks enabling the eventual dominance of intolerance; thereby undermining the very principle of tolerance.
- Comment on [deleted] 4 weeks ago:
Off the top of my head in no particular order:
- sewerage pumps
- fresh water pumps
- telecommunications systems
- refrigeration equipment in homes, restaurants, hotels, factories
- transport infrastructure like street lights, traffic lights, railway crossing lights
- trains, consider for example control of signalling and switching, let alone electric trains
- fuel distribution like petrol pumps
- hospitals
- broadcasting like TV and radio
Essentially society as we know it stops, at least for a while. Generators are used, but are often of limited use, since getting fuel to them is non-trivial and many are scaled for short outages.
Without knowing what happened in Spain, I can say that events like this can and do happen around the world. It’s likely that this will increase.
Given how interconnected the electricity grid is, I’m surprised that this didn’t cascade across Europe.
- Comment on What would this list look like for your generation? 4 weeks ago:
I get the sense that this list is constantly growing and acts as an incentive to invent new words that end up on the list.
By that measure, Emma is a rockstar and Darius is being bullied by their classmates and the teacher.

- Comment on What programs do you wish a good FOSS alternative existed, but doesn't or most of the FOSS alternatives simply aren't good? 5 weeks ago:
You’re welcome.
I understand that being able to write software and be deliberate about accounting gives you a closer relationship with your financial situation.
For me the issue is that there are no guardrails around the plaintext accounting model, which means that you have the freedom to shoot yourself in the foot.
My current accounting software as rubbish as it is, stops me from making stupid mistakes, credits instead of debits for example. Plaintext accounting won’t.
So either you need to never make a mistake, or have a way to figure it out.
All that kind of safety net doesn’t exist. You can still make the books balance, but at some point you’re going to find a hole and spend weeks fixing it, or the taxman will and you’ll be paying a fine.
I exported the line items from my current software into plaintext accounting, even made it balance and match my actual accounts.
Then I needed to write an invoice and had to make my own, from scratch and manually enter the data twice, once into the invoice, another into plaintext accounting, giving me the chance to make an error twice, perhaps even a different one on either process. And that’s just one invoice.
I have considered writing my own accounting software from scratch, or forking something, but that’s not going to pay for food, so I kept looking instead.
It’s not a great place to be, either from a business perspective, or a mental one, but that’s where I’m at.

Plain text accounting (and all the variants) sounds great, right until you need to use it to generate invoices, or depreciate assets, or do a monthly Business Activity Statement, or convert a currency, track repayments, etc.
All of those things require that you write software to achieve that, which means that now instead of solving problems and writing software for my clients, I’m burning hours writing software so I can run my business.
Even if I did that, I’d have no way to validate the processes, short of becoming an accountant.
GNUcash, held up as an example by anyone you ask has no documentation for importing data, has no sample company datasets, has no Business Activity Statement, continues to prefer using an XML file as a database and is unreadable on a 4k monitor.
Kmymoney is fine for home users, but specifically not for business.
Odoo, Adiempere, ERPnext and the six or so other ERP tools have poor or non existent documentation, same issues as GNUcash in relation to data and import, and have a poor track record in solving basic issues that are completely unacceptable in a business setting. For example ERPnext didn’t do currency fractions properly (ERPnext uses Centavo instead of Cent for the USD fraction: github.com/frappe/frappe/issues/13445, took 13 months to fix).
Last week I evaluated Apache OFbiz. It looks like a product from 1995, and trying to find anything is impossible. For shits and giggles, try setting the global date format to yyyy-mm-dd. There are three different repositories and the Docker installation instructions don’t even bother to include which one to clone in which order. It starts at: “run the docker build command”. Not to mention that it uses a database called Derby. I’ve been writing software for over 40 years and until last week I’d never heard of it. That’s not something you want in business software.
I could go on, I’ve tested dozens. This is just from memory.
Why did I test all these?
Because I’m still running a 25 year old accounting package that doesn’t run on current hardware, isn’t supported, doesn’t run under Linux and has all my data hostage.
- Comment on What programs do you wish a good FOSS alternative existed, but doesn't or most of the FOSS alternatives simply aren't good? 5 weeks ago:
Business Accounting software under FOSS is abysmal. Poor quality, poor documentation, poor functionality, limited locale support and limited local support.
CAM software under FOSS is limited to three axis at best, but most is two and a half axis.
Office functionality is covered with LibreOffice. Your assertion that it’s 20 years behind is in my experience not based in fact.
Source: I’ve been using FOSS for over a quarter of a century.
