Oh, that pre-web, text only POS document. Yeah, you're right on top of modern Usenet use. You're a fucking retard, boy. Write that.

You can buy a laser module that projects crosshairs for a few dollars. There are inexpensive gimbal systems for UAV camera stabilization but I don't know if they have an adequate feedback mechanism for your purpose. They're typically BLDC motors. -- Best regards, Spehro Pefhany

I have rfc3977 too, not the rfc6048
>Brackets are a good idea these days.
Well I have seen all sort of things in Usenet, at one time people started posting in html that has stopped, binary attachements.... There is, AFAIK no standard on how to put a link. Brackets are a nuisance as links are just text and cut and paste (Linux double click) then also takes the brackets that you then have to remove. I usually put the links on an empty line I can have cut and paste remove any brackets, but thare is more than usenet links to copy. Many people do their own thing, Usenet is a free world, imposing your ideas on others is your problem, I do not HAVE to use / read it.

Yeah, but if you ignore RFC2549, the receive end won't know what to do, and... then your goose is cooked, as the saying goes. In communication, it's wisest to adhere to any available convention. Even if it means greek letters like pi and omega show up... or phrases in Latin that are repeated ad nauseum.

Well did you notice most people here put the links as text without '<>'. Not only in this newsgroup but im all groups I read, Do not force crap limitation standards on others, same as was with html. If people are too dumb to download a link no need to engage with them. Usenet is free format, go by rfc. Get a good newsreader And anybody who can read and cut and paste and use Linux can use wget to get a file: wget http://panteltje.com/pub/this_is_watching_over_me_IXIMG_0746.JPG end of discussion, that downunder insulting guy is beyond help. the other slow one too. My mistake, had the filter off.

You're an abject idiot. You come here and type in English. Is English your first language? If not, you are "conforming" to a convention. That being that since most in this group use English, you get the best results from following suit, which you do. You discounting a known convention as this(yes it is, putz), is just like a retarded Trumper discounting the efficacy of masks worn indoors to stop breath clouds from happenning. You're an idiot, but a free idiot. If it were truly a free world I could freely fuck you up for being so blatantly stupid. You should be glad that it is not really as you claim. The line is called civility. You want to claim to be civil, then act civil. You want rank individualism, then you are one rank indiviual, motherfucker. As in you stink, boy.

Your whore mother forced a CRAP piece of shit (you) on the world when she failed to flush you. She forced a crap limitation on others. She should go to prison. "limitation"? You really are a complete fucking idiot.

This panjan retard ran off. What a pussy. Hey JanPanTardje, you're a pussified dumbfuck who got caught with your "I follow conventions" pants down. Once caught, instead of LEARNING, you still bark out childish baby bullshit. Good, job, pussified putz! NOT! Just like Trump and his Trumpers. How did you get so fucking Trumplike stupid way over there, boy?

There /is/ a standard - you put < > brackets around the link. It has been the standard of Usenet and email for a long time (probably since email and the web left the realms of universities and technical users, and became popular with the great unwashed). Every decent client program understands < > around a link to ensure that it works correctly regardless of where the text line breaks go.

Bracketed links are single-click from any decent newsreader on Linux.

This newsgroup is a fine testament to people writing exactly what they want with a total disregard for anyone else. But if you want people to follow your links, then it is best to follow the standards.
