- Comment on trying to fix a wifi antenna need some help 😅... 2 days ago:
I don’t know what your specific antenna looks like.
Generally you connect close to the centre of the antenna, where the two elements are closest together, again without touching each other.
That said, there are antenna designs where this is not true.

Give us a link instead. That said, read on.
In general, antennas are not like a “normal” circuit where things need to connect to each other to work.
Most antennas are made of two halves or poles, hence the name, dipole.
A Yagi antenna is a dipole with separate elements to focus and reflect the radio waves. These elements are normally not connected to each other.
In a typical Yagi only one pair, the dipole, is the driven element. The many (shorter) elements are directors, the one (or two) behind the driven element is the reflector.
A coaxial cable has two conductive elements, the core (the middle bit of metal) and the shield (the outer braid). These should normally not connect to each other.
You connect each coax conductor to its own dipole element. It generally doesn’t matter which coax conductor connects to which dipole element.

- Comment on Mods, what tips or etiquette do you recommend for reporting? 4 days ago:
Is this not a slightly selfish action? It solves the problem for you, but doesn’t make the community better for everyone. I feel like blocking users should be reserved for issues like harassment, not spam.
This is an aspect that I had not considered. Even thinking about it now leaves me unsure of the best way forward.
Specifically, whilst it’s a valid argument that blocking the user only solves this for me, and not blocking would help me see if the issue was dealt with, I feel that leaving the user free to roam across my screen is impacting me directly and if I’m not a moderator in a community, it’s not my place to second guess their decision to leave such a user and post in place.
In other words, I’m stating to a moderator that I think that this post is spam and should be dealt with accordingly, but if you leave it alone, that’s your choice.
I moderate several communities outside of the fediverse and spam in my communities is a one-strike ban. That’s not what everyone does.
Having now thought through this again, now in more detail, I’m comfortable with blocking the user.

I’ve noticed a sharp increase in spam and I’ve been reporting each one simply as “spam”.
I then block the user
Many of these posts have dozens of down votes.
Several go back months, which I discover when a new variant turns up.
I’m unsure if what I’m doing is helping or not, and as an ICT professional, I’m not sure why this obvious spam isn’t caught earlier.

You mean the information superhighway?
- Comment on What is the General Consensus of Web3? 1 week ago:
The term has been embraced and extended by the bandwagon of popular “journalism” in exactly the same way as “artificial intelligence”, “block chain” and plenty of others before then, “interactive multimedia”, “internet ready”, “plug and play”, “desktop publishing” and “turbo” to name a “few”.
- Comment on 85,000 Police Officers in the USA have been investigated or disciplined for misconduct over the past decade 1 week ago:
Australia doesn’t even have that many officers in total, “only” 65,000.
However, it turns out that the USA appears to have less police officers per head of population when compared to Australia.
- Comment on What are these "bass" and "treble" that I see in an equalizer ? 2 weeks ago:
In addition to the comments made in reply to your question, something else to consider is that all loudspeakers and ears are different.
If you want to faithfully reproduced the original sound, you might need to tweak the audio using an equaliser.
If you have tiny speakers for example, you might need to amplify the lower frequencies, the bass, and suppress some of the higher frequencies, the treble, to compensate.
Deafness is not the only thing that happens to ears. For example, my ears have trouble hearing much above 2 kHz, so I often need to suppress the bass and increase the treble to make stuff properly audible, since otherwise the bass overwhelms everything and I can’t understand what a person is saying.
Finally, sound is based on vibration of air. Slow vibration makes low sounds, fast vibration makes high sounds. The speed at which the vibration happens is expressed as a frequency and the name for it is Hertz, or Hz. 1 Hz is once per second. 10 Hz, is ten times per second. 2 kHz is 2000 times per second.

My first networked computer, on an AppleTalk network was called “()/)/)/()”
Ir was an Apple Macintosh IIci.
It had that name for less than five minutes. That’s how long it took the network manager to find me and demand that I rename it to something that didn’t appear at the top of the Chooser, since that’s where the ADMIN NetWare server should be.
He suggested “ob1”, and that’s what it has been and continues to be for the past 32 years. My laptop became ob2.
Servers under my custody are called short words, generally four characters or less unless they’re disposable and they don’t get a name beyond what the installation process creates.

It is. It was started after my observation here.
A foundation that’s looking for donations should be showing exactly how it’s spending money. As one comment in the thread points out, the current reporting falls well short of the UK minimum reporting requirements.
No doubt these requirements vary from country to country, but having to guess where the money is going is never a good sign.

- Comment on What existing platforms do you wish were federated? 2 weeks ago:
Shame that all those business models require US centric payment processors to actually get paid.
I’m not in the US and my choices for actually getting money into my bank account are PayPal or Stripe, neither of which have policies that permit the distribution of electronic data or alternatively donations without being a registered charity.
Neither has dispute resolution procedures that go beyond “you broke the rules and we’re keeping your money”, and “sorry, that was a fraudulent card and we’re taking the money back, plus a fee, and the fraudster keeps the goods”, and finally “our word is final and we’re now closing your account without disclosing why”.
So, yeah, good luck with that.

When I clicked on the link I got an annoying “Subscribe Now!” that covered the bottom half of the screen. It had a minimise button. It came back once, but again had a minimise button.
I was able to read the article.
I agree that a summary would have been helpful.
