At the risk of being insensitive, is SlideRuleEra still around? I was trying to access www.slideruleera.net this morning and that site appears to no longer exists. I don't suppose anyone created a copy of all the data that was there?

pham, I don't suppose I can trouble you to try the link? I'm hoping it's a weird firewall thing since I'm in the office.

It would be great if Eng-Tips could maintain it in the future as it contained a lot of valuable information which is not readily accessed on the internet.
RE: Slide Rule Era
Unfortunately, it doesn't archive PDFs.

RE: Slide Rule Era
Rats. That's really unfortunate.
Teh, thanks for the waybackmachine link. I was at least able to see what SlideRule had out there. Also, I was able to still access at least one of the pdfs.
The reason for this search is I'm going to be adding some equipment to an existing floor. Built approximately in the mid-90's, it's a 3" total thickness concrete on metal deck. I'm trying to hunt down info for it. Right now, all I have is a massive point cloud to measure from. Based on what I'm seeing in the measurements, it doesn't match any profile that Vulcraft currently has. See the snip below for the horizontal dims. Vertically, depending on which points I pick, I get anywhere from 1.2" to 1.37". If anyone has any suggestions for where I could find info on this, I would be very grateful.

SlideRuleEra - any chance you could bundle you website's HTML files and your uploaded docs into a ZIP file that could be downloaded and viewed locally?
RE: Slide Rule Era
This page seems to have some PDFs archived, as least, the first couple of links https://web.archive.org/web/20190518213632/http://... Others seem to have never been captured

RE: Slide Rule Era
winelandv - Using the Wayback Machine, if you can determine which document likely has the info you need, I'll be happy to upload it here.
CrabbyT - Considered doing something like that and made an estimate of the total size of files on the website... stopped counting when it passed 3 gigabytes. Will take another look.
RE: Slide Rule Era
Thanks for reaching out. Unfortunately, it appears that steel decking was under-represented on your site. I was able to grab the pdf for the "ICBO Report - Robertson Steel Floor and Roof Deck (1980)", but the profile I have didn't match any of the Robertson profiles. I have an email out to the SDI and hopefully they will be able to find something.
Thanks for hosting that site for as long as you did - it has been very helpful to me at various points in the last 12 years.

I have about 950GB free in my OneDrive at the moment, and it's not filling up that fast. I'd be happy to store it for a bit while something more public is set up.
SRE - to reiterate what others have said: thank you very much for your presence here on this forum and for hosting your website for so many years. You've provided an invaluable service to this community that we all appreciate, both as the unofficial forum librarian and as an incredibly deep resource of engineering knowledge.

My son has a website and we may be able to use his servers, too. I often use his website to transfer several GB files to clients. I send the files to him and he creates a link on his server for the client to download from.

I think your accumulation of historical engineering design documents is an irreplaceable asset.
I would be willing to help out in preserving these documents. I can help fund a pool of money to keep the documents stored somewhere; or help out in any other way if needed.

RE: Slide Rule Era
Why not set up a Gofund me page to pay for the website at least for another year or so and then see how to maintain it later?

thank you very much for your "valuable presence" here on this forum and for hosting your website
Iam sure you well got rewarded in this life and in the LASTING LIFE.
RE: Slide Rule Era
Just for info, the reason I took down the site is not about money, health, etc. The site was hopelessly outdated and I do not have the webmaster skills to update it... and of course, there is no more room at home for human909's bulky tape drives, and it is getting harder and harder to find replacement vacuum tubes for my computer.
Many thanks, again. I'll be back in touch on this subject when I get the files together.
RE: Slide Rule Era
RE: Slide Rule Era
1) Have Eng-Tips host it if your relationship with management is amenable to that. It would be a service to the forum and, in a small way, help to drive site traffic. This would be my first choice.
2) Celt83 has a website that is coming together nicely and is substantially in the vein of what I'd once hoped KootWare would be: The Structural Toolbox. Perhaps, with some financial support, we could persuade Celt83 to add the SRE stuff to the existing infrastructure of his website. Again, this would benefit our community and help to steer traffic towards the excellent online tools that Celt83 has been developing.
3) Agent666 also has a web presence that might be used similar to Celt83's: Engineers Vs Sheep.
For years now, I've foreseen this eventuality and meant to reach out to you to see if you might want me to succeed you in your endeavor. I'm kind of the world repository of historical structural engineering publications in my own right so there would be synergy there. I'd still be willing to do this if it were necessary but, at present, I'd be pleased to see this land at one of the three options above or something similar.
RE: Slide Rule Era
Another useful place to add it would be to this github repository https://github.com/open-struct-engineer (assuming the repo owners are cool with that). If its on Github its very likely to remain available for a long time, moreso than any 'private' website.

In my mind, the cost of hosting would be one of the things that would favor storing the files here at Eng-Tips. I'd have to think that would be a drop in the bucket of the data storage overhead already incurred here.
RE: Slide Rule Era
On the other hand, she has always supported my website efforts and ET participation... "you never know how many people you are influencing for the better".
KootK - Excellent ideas, I have time to sort out the next step while getting the files (3.5" floppys) DoubleStud showed into neat stacks.
ggcdn & Celt83 - You are so right about copyright. About 15 years ago I heard from the Portland Cement Association about posting my scans of their 1930's (active) copyrighted publications. To make a long story short, the incident ended well for both PCA and me. Decided to start a DIY education on fundamentals of USA copyright law. I maintain an obscure FAQ in the History Forum: "US Copyright Law Basics for Printed Publications". In fact it is time for my annual update of that FAQ with start of a new year... 1927 publications entered the public domain on January 1. To the best of my knowledge, all posting on my website were "clean".

But when you bought a program it used to come with a small mountain of 3 1/2" floppys which you needed to insert IN THE RIGHT ORDER or hell and damnation was wrought upon your PC.

It is an 8' long slide rule that was used by a local high school math teacher. He gave it to me when he had to clean out his house and move to a nursing home.
We recently mounted it in our office and it is quite the conversation piece!

I also added a few that weren't on SRE's site, like NBC, historical state codes, etc.
Some of the links may be broken, but many are working. The links to Google Books dont work for me, but I'm not sure if that's because I'm not American.
The list is available here

Slide rule is going to ask what you're after specifically, I'd wager, so they can upload it.
A list of the files, now that would be something, just an index of the stuff. Or inventory. Whatever.
RE: Slide Rule Era
The link to the WayBackMachine image is as good an index as I ever had. Website was started about 2005 just to see if I could do it (my stepdaughter gave me a half hour of basic instructions on how to proceed). That's why it had such a quirky look. Had no clue that the outdated info would actually be of use. In 2005 there were few websites with that type content, many more these days.

That's a bit unnerving given the amount of time that's elapsed on this thread (13 months) and how important your site obviously is to the community here.
Here's one, temporary solution that I would be willing to help with:
1) My Dropbox for business account currently has 6TB of empty space on it.
2) I could create a sub-account to my Dropbox account for your use. No one but you could access it without your permission (not even me I believe).
3) You upload your file set to the Dropbox space via synch or direct upload as you see fit.
4) You distribute the files as you see fit or have me do it on you behalf following whatever protocol you specify.
5) In the future, perhaps you have someone else host your stuff on their web page per your wishes.
This way, at least:
a) Members of our community can get the information that they seek one way or another and;
b) Your creation doesn't have to die/retire with you should you get hit by a bus or decide to focus on your putting game.
c) This wouldn't cost either of us anything in the short to near term.
RE: Slide Rule Era
What I MAY be able to do, over time, is compile a limited group of the "best" documents and turn them over to you or someone else to take it from there. There are other sources (say, AISC, Internet Archive, commercial websites, etc.) for a surprising number of files that I originally scanned and posted. (For example, AISC's website offers the historical reference "A.I.S.C. Iron and Steel Beams 1873 to 1952"... they use my unaltered scan of the entire book, and that is fine.)
RE: Slide Rule Era
Calibri may be helpful in your effort to organize the files: Link
RE: Slide Rule Era
RE: Slide Rule Era
RE: Slide Rule Era
Would you be willing to create a Google account, upload those files into Google Drive, and share it with the public?
Google Drive gives 15GB of space for free, you can access it through your web browser, and all you'd really need to do is drag/drop some files and let em upload.
Maybe someone else would be willing to pick up the torch if they had the files.
RE: Slide Rule Era
Edit: Just saw that KootK offered this as well, should've read that first
RE: Slide Rule Era
RE: Slide Rule Era
I'd be happy to relieve you of that burden as well if you'll have it.
Just synch the files to my Dropbox as they are, where they are. I'm willing to sift through them one at a time to organize them.
I imagine a process like this:
1) I use the existing echoes of your website to work out the document list to the best of my ability.
2) I open the documents one at a time if there's no better way and match the files to the list.
3) I create a document list in Word, Excel, or whatever where each document is listed with a hyperlink to it's Dropbox location.
4) I post a Dropbox link to the document list, titled "SRE's Legacy" in my signature here until we find a permanent home for the reincarnation of your website.
Just say yes, to me or someone, and we'll get this done somehow.
Given the Spartan setup of your website, this solution wouldn't even be much of a functional compromise I feel.
RE: Slide Rule Era
CrabbyT - You have come up with something I should be able to do, not right of way but soon. I'll get started on uploading to Google Drive and post back here when all is ready.
Please understand, that I will be making the files available for download for a short time. I am delighted to provide the files but will leave it up to someone else to organize and host them. I'm out of the web hosting business, never got any better than when I started, but had a lot of fun with it for 17 years.
Whoever takes on this project is in for a really interesting time. I would hear from engineers and others all over the world, with requests to include website items in forthcoming engineering books, submitting documents for possible inclusion on the website (a retired engineer I never met mailed me two large boxes of his old engineering book for free - refused to accept my reimbursement for postage), even a part time (paid) job offer from Professional Publications, Inc. to do behind-the-scenes technical editing of some of their first-line books (I took that offer, resulting in some eyeopening results... for them).
RE: Slide Rule Era
Just an invaluable amount of resources, many of which do not exist literally anywhere else.
Don't worry about organization or number of files or size. I think I speak for almost everyone that those things do not matter even in the slightest. We are all oozing with cloud storage space.
Let it all upload in the background, share a link, and the community can take it from there.

SlideRuleEra Do you still have the web domain, and would you be open to us resurrecting the site on that domain?
I've downloaded some of the references locally throughout the years, I'm sure many others have some as well. If we get a site started I think we could start repopulating the website until SlideRuleEra has a chance to get the files together
RE: Slide Rule Era
CrabbyT will be able to start over fresh, which I expect is the best way to do this.
RE: Slide Rule Era
Also, if at any point you want to use this site as a platform for Giving Away Structural Engineering for Free ® (ref: https://www.eng-tips.com/viewthread.cfm?qid=483020 ), consider me on board. We can talk about it more later, but I've had ambitions of doing this as well. Maybe that could be a different site if you still want to do that, or maybe we could figure out a way to put them under the same umbrella as this historic docs repository.
skired - that's awesome, thank you and your friend for offering to help. I'll figure out the registration and hosting costs and will let you all know. It would be awesome if we could eventually raise enough through donations to register this site in perpetuity.
On the subject of donations/crowdsourcing this effort, do you guys have any recommendations for how we should facilitate that? I was thinking a GoFundMe could work, or maybe PayPal. Venmo and etc. would be fine IMO. It would be good to use something that converts funding automatically. KootK mentioned $CAD, I generally operate on $USD, but I'm sure there's some platform out there that would facilitate currency exchange.

RE: Slide Rule Era
RE: Slide Rule Era
Incidentally, it looks like the internet archive more or less saved both the web site structure and a lot of the PDFs. So if somebody wanted to scrape the files from there and just let SRE know what wasn't archived (that SBC link doesn't have the source file anymore, I suspect because it's an external link that the ICC got taken down?).
If anybody wants to expand this, I could maybe be persuaded to send some old steel joist catalogs, but I'd want them back after they were digitized. It would be a trip if we somehow assembled all the SJI catalogs, for example, but I don't have anything that's not readily available on the internet in that vein. I have some middle aged Vulcraft catalogs is all. Like 1998. Maybe one earlier one that if I remember right had a reddish cover and was staple bound, perhaps that's an SJI catalog from around 1990.
