I’ve noted (or at least hinted) that one thing that I am scanning is film negatives. Why scan film negatives?
Again, I reiterate, because this is important!
Film negatives have the following advantages over prints:
So, once you create your first and minimal GitHub pages Jekyll site, what else is required for local development? Easy, just follow these few steps.
-
Make sure you have the local Jekyll development environment setup, i.e. follow the instructions in installing Jekyll.
-
Add the following contents to the Gemfile in your repository:
source "https://rubygems.org" gem "github-pages" -
Run
bundle install:bundle install --path=vendor/bundle -
Add any necessary plugins to your
_config.yml. For example:plugins: - jekyll-paginate
It’s that easy! Sure, not quite as easy as going to publish directly to GitHub pages to see how your site looks, but much faster for adjusting styling, for example.

So, you’re earlier questions about photo mapping individual papers? The answer is obvious when you integrate with the digital library methodology. Of course, all individual sheets of paper must be aggregated into larger bundles, such as reams of 500 sheets. Now, placing that into the photo map is easy. The same principle can be extended to smaller objects too, that they must be contained within some kind of larger case together.
On the other side of affairs, in the scan to digital library world, you want small objects to be aggregated together into larger objects, but not too large all at once. Papers should be packaged into reams of no more than 500, then the reams can be placed on shelves or in boxes for larger scale aggregation.
Finally, this rule extends to all other small objects too. Just like a ream of 500 sheets of paper, every small object should be solidly held in place so that they retain an “address” that can be consistently navigated to. No bags where things can swish around and require searching are allowed. So yes, this does mean that you should create one of those nifty cases that has styrofoam filling up the space in the case, and cut-outs in the shape of each tool that fits securely in its place. It’s not just an eccentric overly-organized way of doing things. After all, once you create the cut-out where each hole is in the shape of each tool, you can assign numbers next to the holes.
So, what really is the fastest camera technology you can get in 2018? Well, as it turns out, I’m disappointed. The fastest technology isn’t that much faster than the technology I currently have.
Standard SD max write speed is 25 MB/s. UHS-I brings that up to 104 MB/s, and UHS-II brings that up to 312 MB/s. CompactFlash has been retired from updates, so it’s not getting any faster in speed. The new standard to replace it is XQD, based off of PCI-E and with a max speed of 1 GB/s.

Terabit bus? Is it possible? Yes it is, but currently only via fiber optic systems. Well, anyways, my hope is that smaller electronics will be able to scale up to bus speeds that fast. Intuitively the gigahertz clock speeds of modern semiconductors would limit the bus speed of serial communications to gigabit speeds. In any case, we need a way around that limit that we have approached too soon already, if we want to be able to keep increasing the speed and resolution of our camera systems.

And don’t worry, 16K resolution is coming here too. Pundits are also touting 16K resolution at 240 Hz being supported in newer GPUs.

For now, we’ll be stuck in the “slow lane” with camera technology. Well, most of us. Only those willing to pay 10 times as much to get a fast camera system today will have one that is 10 times as fast. And I mean, come on! You only get 10 times more speed for 10 times the price? That can’t seriously be worth it! At least not from an economic standpoint. An exponential growth curve would assume 100 times the speed for 10 times the price.

- UART serial communications
- Command-line based user interface
- Login managers
- An unchanging implement now on modern desktop computing. Optional for single user systems, but even for kiosks, a “login screen” is used to display messages such as terms of service before the user may use the system. Also, to make sure the next guest user has a clean slate to start from, and confidential information doesn’t leak from the previous user.
- Terminal user interface, i.e. two-dimensional smart video display terminal
- Pseudo-terminals and terminal multiplexing, i.e. Emacs, GNU Screen, tmux.
- Bitmapped raster graphics screen
- Window Manager
- Only rectangular windows need to be supported! Overlapping and transparency can be used to give an illusion for non-rectangular shapes.
- Widget library
- Themes/styles

Raspberry Pi notes.
Come on! Do I really have to buy an expensive video display if I want to have a Raspberry Pi like a standalone computer? Not so. I’ve got a handful of old laptops around that already have those expensive LCD panels inside of them. All I’ve got to do is connect them to the Raspberry Pi.
So, what is required for this? Basically, you have to buy an LCD controller board to connect to that LVDS interface already on the panel. These run for around $25, but they can be more expensive if you build your own from an FPGA. Make sure you get the right controller board for the monitor you have. Purportedly, those with VGA output are cheapest, so you’ll have to use that standard HDMI to VGA converter with your Raspberry Pi. Other than that, you should be able to reuse all the other parts. Unfortunately you’re going to have to reverse engineer many other details such as the pinout, the specifics of the LVDS data format, etc.
