BUNKEROFDOOM.com site??

Hi Patrick,
I've been using Interserver.net for my dedicated domain servers for about 15 years. The uptime has been stellar and the Customer Service is outstanding. When I signed up with them the cost was only $54 per domain and that price was locked as long as I kept the account. I think they are up to $64 for the basic server now with optional upgrades.
Check them out:

The site is de-activated.

Indeed it is. At this time, the site exists locally in a few backups. It's a good time to do a major cleanup and improvement.

Removing unneccessary files.

Trying to put scanned publications that are made up of hundreds of individual JPG files into a single PDF, e.g. the RCA Tube Manual and some Transformer Catalogs. The old Sylvania tube manuals will be left as is (html based) because they already include an index of links like the Frank tube site.

Maybe updating or checking for updates for some material where I have previously gotten permission to mirror some resources.

Adding links to the main page to deliver many existing but unlinked files that were at some point uploaded and forgotten.

Adding new scans.

Somewhere, I think I might have most of the Triad transformer catalogs page by page scans at full resolution, but they need cropped, every single page, and put into PDFs. The resolution is higher than the resources presented online by Triad. I have to ask permission.
BTW Cropping a stack of images which may or may not all have the same cropping sizes and coordinates is no simple task. I don't have automatic  or batch software for that, it may not exist in my $0 price range.

A programmer friend suggested using some automation to fix up the case issue and also to apply CSS site-wide to be consistent.

About trying to put scanned publications that are made up of hundreds of individual JPG files into a single PDF:


IRFANVIEW will do it and with as much or little lossy compression as wanted. I try to go uncompressed. The "Westinghouse  Annual Catalogue of Electrical Supplies 1920" of 1488 pages at 4000x6000 turned out to be 4.2GB. This was done as a test of the software. It not only converted jpeg2000 format to jpg, but also put them in a PDF.
It should have been closer to 1.2GB at the same quality, but that was my mistake in eschewing all compression.
Irfanview can also use multi threads, but if that's turned ON, even with only 2 threads, then it can run the cpu up to 75%. Fast work but can overheat the processor after a couple minutes. The only cure is to control the power setting on the PC to 'eco'/green/LOW, meaning lowering the clock speed.

The happiness factor of large image size/lowest compression scan is that one does not get a headache from trying to refer to the small print and image details in the weighty tome.

This can not be said of the 184MB PDF available online for download. The point is that a lower-rez version is what most people want, and what more serious others need for a preview.

archive.org saw fit to include all the 4000x6000 source pages as well as the 184MB PDF document, so that devotees who had first read the 184MB file could decide to get the full resolution materials and could reassemble an excellent-looking and visually accurate volume from them.

The halftone dots are distinguishable as pixels in those 4000x6000 images. I have to give that site a lot of credit. Many documents include the raw or highest resolution scans as downloadable items.

The only thing I could not do to make it better is auto-crop. The main blockage looks like the right and left pages, as in a bound document. Cropping according to coordinates plus right and left offsets didn't seem possible, but I'm going to try again.

Hope all that made some sense. When the site comes back, I want it to have some improvements, or less annoyances in any case.

Thanks for all of the horrendous amount of work you have done Patrick and are doing to archive the antique and boat anchor documentation that makes it convenient for the rest of us to keep old gear going, the education the material provides, and for the sentimentality of just looking at the papers and remembering the good old days.

the site is being hosted again, though some items are still 404. Someone else is hosting on a private machine but no one's working on it.
