Re: Steve Stewart Postings

Very nice images and content added to http://newmars.com/forums/viewtopic.php … 31#p204631 usefulness of caves for a first underground habitat of mars.

I was able to get an account to post an image that was transferred from my cellphone up link for the computer to it via the micro-usb port earlier today.

Re: Steve Stewart Postings

It is also why we had a wiki page long ago but its seems that manpower is the issue.

Re: Steve Stewart Postings

For Steve Stewart ....

It appears you may be able to submit your paper directly.... please visit the Mars Society Papers page ...

MarsPapers
The official library for the Mars Society
Home Papers Publish
While most of the documents in this archive have been presented at the Mars Society annual Convention, we encourage everyone with a Mars related paper to submit it for inclusion in MarsPapers where it is available for public reading. You may email your paper for inclusion in the MarsPapers archive to the Editor of Mars Society Proceedings fcrossman@marssociety.org, even if the paper has been presented or published elsewhere as long as you, the author, have retained copyrights to your paper and can give permission to the Mars Society to publish your paper in the MarsPapers archives.

To submit your paper to MarsPapers, first download and read the TMS Author's Instructions.

MarsPapers Policy Statement

The Mars Society accepts for posting in its Marspapers library any formally presented paper that meets the requirements of the authors' instructions formatting and is accompanied by the signed copyright license agreement and which bears a relationship to the purposes of the Mars Society, the founding declaration of the Mars Society, or to Mars in general.

In the spirit of openness to the expression of all ideas that cut across a wide range of topics and expertise, the papers presented at Mars Society Conventions that are submitted formally for publication by the Mars Society and/or for inclusion in the MarsPapers archive are not peer reviewed, although specific abstracts and papers may be deemed unacceptable if they are considered to be primarily unsubstantiated opinion or a tirade or if they are deemed socially or politically offending in some way. Peer reviewed papers from other organizations and journals are encouraged for posting in MarsPapers if the author has retained copyright and will give the Mars Society permission to post the paper. The Mars Society also encourages the submission of responses to posted papers or preprints of papers prepared independently, subject to the guidelines discussed above.
Please contact the Mars Society Webmaster with any technical problems using this site.

Re: Steve Stewart Postings

For Steve Stewart....

There are other media where your work might be a good fit.

Are you interested in exploring other possibilities, in addition to the Mars Society Papers department?

I am wondering if the National Space Society might be a possibility?

The Space Studies Institute would be a perfect fit, if it were still in operation.

Your paper would have been a natural fit for one of Dr. O'Neill's Space Manufacturing Conferences at Princeton.

***
I'm piling a lot on your plate... Please look at My Hacienda, to see if there are specializations not present there that you would need to implement your soil creation concepts.

Re: Steve Stewart Postings

Tahanson #8,
Thanks for all your information. I would be interested in posting it on other media's later on. Right now I'll look at the Mars Society papers. They have a lot of information as you pointed out. It'll take me a little while to go through it and convert my files to their format. I'll get back with you later on the other media sights. I'll take a look at My Hacienda On Mars as well.

By the way, I did run across a few "server errors" while test posting my proposal. I had to break post#8 of my proposal into two parts, which became post#8 and post#9. Apparently when a post is too long it creates an error, which I think you have mentioned. Another interesting thing I ran across was in post#12 of my proposal. When I posted "trace gases)." in the first paragraph of post#12 I got a server error. When I added a space before the right parentheses "trace gases )."  I didn't get an error. I tried different combinations several times and it does not fail consistently. I was unable to get it to post with all the text and space omitted, so I had to post it with a space. When I removed all the text and only left "trace gases)." without the space, it would post okay. I'm not sure what is going on. I thought I'd pass this on, maybe it would help in troubleshooting.

Re: Steve Stewart Postings

For Steve Steward re #9 and specifically the Apache Server error ...

Thanks for your reporting on the problem, and your experiments to try to discover a pattern ...

Several of us have tried a variety of procedures to deal with the problem once it shows up.  I collected a number of references to the problem and posted the list in Housekeeping a while back, but I never had time to investigate them.  Since Mr. Burk was promoted to Executive Director he's been too busy to continue as webmaster for our site, and (as far as I know) the Society has not found a replacement volunteer with the needed expertise. 

It appears (I have no direct feedback) that the Society may have moved NewMars to a different server ... we had a period of time when DNS cache had to be rebuilt.  That is a sign of a hardware move.  In addition,. our email service has become far more reliable than it had been until the move.  From this I deduce that ** something ** was done, but we have no way of knowing what.

There is a great deal of information on the Internet about this particular problem, and (apparently) there may be solutions recorded as well.

If someone with experience in IT wants to investigate and report findings, that would be welcome.

As things stand, it seems to me the episodes of the problem are less frequent, but your experience suggests that the large post trigger is still there. 

While I'm thinking of it .... Google Drive offers a full 15 Gb of free storage, and it is possible to link to files on Google Drive using their "share" feature.  I've been using this lately, and it seems to work well.  Apache seems to wave short posts with such links through without a problem.

Your entire publication could have been served that way.

We are doing something similar using Dropbox to serve Dr. Johnson's class modules.

Speaking of that !!! We have summer vacation coming up, and it would be great if one (or more) of our members could publicize the class in the local area.  The class is free for anyone to download.  Dr. Johnson is offering to help students via email or even a phone call, but that willingness is probably limited if a lot of folks take the class.  At this point, I am not aware of anyone downloading the material and starting in on it.
