Readers! A November fund-raising drive!

 

It is unfortunately time for another November fund-raising campaign to support my work here at Behind the Black. I really dislike doing these, but 2025 is so far turning out to be a very poor year for donations and subscriptions, the worst since 2020. I very much need your support for this webpage to survive.

 

And I think I provide real value. Fifteen years ago I said SLS was garbage and should be cancelled. Almost a decade ago I said Orion was a lie and a bad idea. As early as 1998, long before almost anyone else, I predicted in my first book, Genesis: The Story of Apollo 8, that private enterprise and freedom would conquer the solar system, not government. Very early in the COVID panic and continuing throughout I noted that every policy put forth by the government (masks, social distancing, lockdowns, jab mandates) was wrong, misguided, and did more harm than good. In planetary science, while everyone else in the media still thinks Mars has no water, I have been reporting the real results from the orbiters now for more than five years, that Mars is in fact a planet largely covered with ice.

 

I could continue with numerous other examples. If you want to know what others will discover a decade hence, read what I write here at Behind the Black. And if you read my most recent book, Conscious Choice, you will find out what is going to happen in space in the next century.

 

 

This last claim might sound like hubris on my part, but I base it on my overall track record.

 

So please consider donating or subscribing to Behind the Black, either by giving a one-time contribution or a regular subscription. I could really use the support at this time. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation. Takes about a 10% cut.
 

3. A Paypal Donation or subscription, which takes about a 15% cut:

 

4. Donate by check. I get whatever you donate. Make the check payable to Robert Zimmerman and mail it to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage or shown in the menu above.


Hiding messages using fonts

A new computer technique has been developed that uses subtle changes to a document’s fonts to encode secret messages and data.

Using Columbia University’s FontCode system, however, users can hide messages within unrelated text via virtually-invisible changes to the displayed letters.

Developed by a team led by associate professor of computer science Changxi Zheng, FontCode works with commonly-used fonts such as Times Roman, Helvetica, and Calibri, plus it’s compatible with most word processing programs. Additionally, the hidden messages are retained even when the document is printed on paper or converted to a different file type.

The video at the link explains very nicely how this works. The technology has some excellent potentially positive applications, such as providing a method of finding out if an original document has been modified. It also carries with it a great potential for misuse because of its ability to hide information unobtrusively in a written document.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

    This seems to be an interesting cross between steganography and the font definition work of Donald Knuth.

    And this will make even easier for one time pads or obscure books to pass messages……

    If something is hidden in plain sight, one need only look to distinguish it. The privacy aspect of such schemes is found in the obscurity of algorithm particulars, not in algebraic complexity. I think the potential for anti-tampering (or some signature/authentication scheme) has utility but, again, with caveats.

    Following up briefly: as the article points out, message privacy relies upon use of a (symmetric) key, so the advantage lies in concealing the very fact that a message is being transmitted (at all).

    This is amazing technology. It also scares the hell out of me. Can you imagine the possibilities of encoding top secret documents and files and shipping them everywhere and anywhere and no one would know just by looking at them? Mary had a little lamb = destruct sequence code is 1A2B. Since you currently need a smart phone to see the real message or a computer to see it what about Google glasses or a type of 3D gaming viewer. The rest of the world goes on unknowing while a select few….

    A number of years ago there was a sci-fi show where messages were somehow encoded into billboards and large signs on buildings. Yet wearing a special set of glasses the true message was revealed.

    I admire the engineering, the development etc but the far reaching implications are frightening.
