49G+ -- FACTORS Has Bug?
Message #1 Posted by Paul Brogger on 27 Oct 2003, 10:24 a.m.

If I pass a prime number to FACTORS on my 49G+ while the Angle Measure mode is set to degrees, it asks permission to set radians mode, and halts if I don't allow it. (Example: With trig mode set to degrees, enter "997 FACTORS" <enter> .)

This seems weird, unless there's some mathematical algorithm for determining prime-ness that involves trig. (And even then, should it require a particular mode setting???)

Has this been a problem on the 49G?

Just curious . . .

The 49G acts the same.

This is a known problem, as well as going into complex mode when it is not really needed. People have been complaining a lot about this but hp didn't do anything. I am wondering if anyone is actually doing much work on the CAS since the first bugs of the 49 have been fixed about three year ago.

PS: All questions regarding the 49g+ are better addressed to the newsgroup comp.sys.hp48. This forum would rather deal with problem with older calcs, it is a useum after all.

Please forgive my newbie-ness -- I haven't spent much time with or about newsgroups. I've taken a look, but don't see anything about how to subscribe or join. I must be missing something . . . (and, not doubt, it should be obvious!)

Welcome to the hpcalc world

Either your ISP has some news server and he will explain you how to use USENET, which is the newsgroups.

Or you can use Google's, just go to http://groups.google.com and in the search type comp.sys.hp48

That is the discussion group dealing with all matters related to new and recent hp calculators. You will certainly learn a lot by following comp.sys.hp48

Thank you. I've always known that comp.sys.HP48 exists -- I've just never got 'round to digging into it.

And I encountered hpcalc.org 'way back -- a great resource.

Thanks again!

Google is great for its archives. By doing a search of the newsgroup on Google, you can avoid asking the same question yet again, and also find answers from experts who no longer participate. Note that a good deal of the design of the current RPL calculators goes way back at least to the 28C. You'll probably look a lot smarter if you search for an answer before you ask a question.

But the last time that I checked, there's a several hour delay between updates of Google's server, so for active participation it's not so great.

Your ISP should, of course, allow you to read and post to the newsgroup, but I find that my ISP's server is sometimes rather slow in getting updates, and on rare occasions isn't updated for a few days. Lately, I've been having a lot of trouble trying to post anything through my ISP's server. My ISP agrees that there's a problem, but I guess that it's not a high priority item; weeks later, it still hasn't been fixed.

The best "web-based" *free* newsreader that I've found is at http://mailgate.org/. To use it, you do have to register and agree to its "Terms of Service". Trolls and spammers may find the terms of service to be onerous, but I expect that most would find them reasonable. Read the legalese for yourself. And you do have to login every time; hopefully, your browser will make that easy enough. Note that Mailgate does do at least some filtering; I don't see the obvious spam on Mailgate.

But reading the news on a web-based newsreader has some disadvantages. For example, you won't be able to use your own filters, and you'll probably see things with a proportional font.

After you've registered with Mailgate, you can use your own newsreader with the server "newsreader.mailgate.org", rather a better experience in my opinion.

Regards,
James

Except for existing members, I'm afraid it no longer seems to be free ... https://secure.mailgate.org/subscribe

I wouldnt worry too much. Despite having used usenet since the mid 80's I actually mostly use groups.google.com to browse/post. My news provider is bad at providing anything approaching reliability and is actually a good test of news clients to handle the often baroque errors one gets. (Program fault - core dumped being a common reply when asking for a news item).

This site is privately run and I guess the curator might be upset to see the 'Museum' nature of the site being used for high volume current rants. But all material posted here is invaluable for the future. When we all look back in 5 or 10 years, these insights into a new calculator arrival will be very educational.
