The New phpBB3 Forum is up and ready for use!

RS2 Fora - Sun, 09/18/2016 - 17:22

The new phpBB3 forum is now up and ready for use.

http://reciprocal.systems/phpBB3 (the "Forum" tab up top will take you there).

Please update any bookmarks, then log in to the new forum and reset your password:

  • Log in to the site using your username with your registration email as your password.
  • Click on your username (top right).
  • Pick "User Control Panel"
  • Select the "Profile" tab
  • Click on "Edit Account Settings"
  • Enter a new password, confirm password, and your email for the current password.
  • Click Submit.

If you do not remember your registration email, you can use the "I forgot my password" link to get a temporary password, which you will then have to use instead of your email password.

I am being strict with passwords, as spamming is getting ridiculous (the new forum wasn't even up 2 hours before a spammer showed up). New passwords must contain upper and lower case letters, numbers, and punctuation.

Any posts made to this forum (the Drupal forum) from this point on will not be ported. Please use the new forum.

Thanks!

If you have any login problems, please reply here.

I have the local images and file attachments moved over to the phpBB3 test site. Outside of about a dozen bad URL links, I think we're about ready to move over to phpBB.

I'll leave the test up for a couple of days before making the final conversion run... let me know if you find any problems. I'm going to try to fix the last of the bad links in the current rs2theory database before making the final conversion.

Horace: read your suggestion. The quote function of phpBB does not seem to have that option, unless someone wrote a plugin for it.

I was able to post a test message there and I made a suggestion, too.

Tex, sup, sub

RS2 Fora Comments - Thu, 09/15/2016 - 19:21

I have LaTeX equations working in phpBB now.

Superscript and subscripts ARE working, but the default theme for phpBB3 does not seem to change the font style or positioning, so there is no visual difference. I will address this once a real theme is decided upon.

Fixed the bad URL links.

Also did a lot of work trying to get the bbcode formatting down correctly (spacing from HTML messes up). Message are fairly clean now.

Upgrade to phpBB3 status

RS2 Fora - Thu, 09/15/2016 - 15:45

I am making progress in the conversion. I have a test system up here: http://reciprocal.systems/phpBB3/ if you want to try it out. NOTE WELL: any changes made to the phpBB forum WILL BE LOST when I do the "real conversion." I was able to write a dynamic conversion system from this active site/forum, so we can continue to use this forum safely until I "throw the switch."

Some notes:

  • Users: able to copy basic user information except passwords, which are encypted differently in phpBB. If you want to log in and try out the phpBB forum at the above link, your phpBB password is your email.
  • Equations (done in LaTeX here) are not yet converted to images, as they are here. They remain in LaTeX form until I can find a bbcode plugin that will perform that conversion.
  • Images will still display, but they are not yet attached to the corresponding posts (they still link back to the rs2theory site).
  • Attachments are not attached to any posts.
  • phpBB does not seem to have support for HTML tables, so the tables appear as bbcode tags and are not formatted.

You can play around with the new phpBB3 site and let me know if you find any other problems. I am currently working on getting images and attachments ported over, but phpBB's attachment system is drastically different from Drupal's.

What I have noticed is that these popular programs have very poor database design to them--I don't think ANY database features are actually used, such as transactions or foreign keys for relational integrity. It also looks like the idea of "normalization" has been completely lost... when you make a post to phpBB, you have to finagle the usernames and subject lines in about a dozen places. Not much is actually linked back to the user_id. What is causing the conversion delays is that copying data is basically "pot luck," since there is little documentation on how to load the tables correctly. The trial and error approach is very time consuming, but I am working through it.

Couple other things that I would like to get input on:

  • A theme for the phpBB3 site (open to suggestions). There are lots of them on the phpBB site here: Board Styles.
  • A logo for the new name, Reciprocal System Research Society.

Reply here if you have any suggestions. Thanks.

I reckon the TU is made of 3

RS2 Fora Comments - Thu, 09/15/2016 - 01:54

I reckon the TU is made of 3 discrete directions of motions. Every direction can assume the values {1/N, N}, whose cardinality is 2N (non-zero natural numbers), i.e. 2N "points". This would be the domain of 4 mysterious functions projecting the 1st direction to a point in the 4D continuum, that is a codomain in R^4 (signed reals).

I don't think it's mathematically feasible to project 2N to R. And if it was, I'd be curious to know what these functions are.

RS2 Fora Comments - Wed, 09/14/2016 - 13:12

Points don't exist in "TU" as you call it it, they are created later in the development as multiple motions are related to each other.
Wait for the the migration to phpBB software, like I am.  You'll get your answers then.

Re: Basic premises

RS2 Fora Comments - Wed, 09/14/2016 - 06:34

So given the lack of response I must assume there are no such formulas. I would be surprised of the contrary: I don't think it's matematically possible to find formulas projecting a discrete domain into a rational codomain.

Too bad, I wanted to believe that Larson was really onto something. Maybe he had some valid intuition but I don't think his theory is usable for practical purposes as of now.

'It's Just Too Perfect': Inside the First Gravitiational Wave Detection

Astronomy Magazine - Wed, 09/14/2016 - 04:00
A year ago today, a select group of scientists became the first people on the planet to learn that, after a century of theory and experiments, Albert Einstein was right all along. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) in Livingston, Louisiana had, at last, detected a gravitational wave. The ripple in space-time — a “chirp in the data — emanated from the merger of two black holes that collided some 1.3 billion years ago. This ripple in th

Can the moon make an earthquake worse?

Astronomy Magazine - Wed, 09/14/2016 - 04:00
When an earthquake occurs, it represents the release of years, sometimes decades or centuries, of pent-up stress. Somewhere along the fault line, a section of rock can take the strain no longer and gives way, allowing a tectonic plate to jerk into motion in a series of spasmodic shudders. The factors that determine when, where and why earthquakes happen are numerous, and we’re still a long way from figuring out how to reliably predict them. But, it turns out that one of the many small str
