Welcome to HPR, the Community Podcast
We started producing shows as Today with a Techie on 2005-09-19, 19 years, 2 months, 20 days ago. Our shows are produced by listeners like you and can be on any topics that "are of interest to hackers". If you listen to HPR then please consider contributing one show a year. If you record your show now it could be released in 7 days.
Call for shows
We are running very low on shows at the moment. Have a look at the hosts page and if you don't see "2024-??-??" next to your name, or if your name is not listed, you might consider sending us in something.
mintCast is "The podcast by the Linux Mint community for all users
of Linux." As a community-driven podcast, we like to have as much
involvement from special guests as possible.

In today's show we speak to Adam Matthews about his Disco Pigeon that he displayed at OggCamp2024. He tells us his background, how it came to be, and chat about how he built it.
These are comments which have been made during the past month, either to shows released during the month or to past shows.
There are 61 comments in total.

Mailing List discussions
Policy decisions surrounding HPR are taken by the community as a whole. This
discussion takes place on the Mail List which is open to all HPR listeners and
contributors. The discussions are open and available on the HPR server under
Mailman.
The threaded discussions this month can be found here:
This is the LWN.net community event calendar, where we track
events of interest to people using and developing Linux and free software.

It's been another hectic month here at HPR Towers.
As we discussed on the mailing list most of the time was taken by the
migration to Mastodon, and the implementation of the mirrors on the
Community Content Delivery Network. Some daily stats are been updated on
https://hub.hackerpublicradio.org/hpr_ccdn_stats.tsv
Dave updated his tooling for processing shows and they are now
available on the Gitea repo.
We finally got around to creating the HPR Documentation wiki.
Community Content Delivery Network (CCDN) A location to track the
deployment of the HPR Community Content Delivery Network, that provides
a mirror network for our content.
HPR Website Design This is literally in the whiteboard phase of the
HPR website redesign. Where we can track Compatibility of the clients
subscribed to our feeds.
Useful Resources Where we can link to other free culture sites that
provide useful services.
Requested Topics Where we can track topics that have been requested,
and link to shows that addressed them.
There is also a list with information about Podcatcher and Podcasting
Platform Compatibility. If anyone wants to adopt a player then please do
so.
The section on Workflow will be changing shortly due to Dave stepping
aside, and also the need to distribute to multiple end points. All the
processing will happen first, and then all the checks will be done at
the same stage just prior to posting. For this to work we need help
finding a simple manageable WYSIWYG editor that can produce sane HTML
when the host uploads the show. We also need a new system to distribute
the files from an origin to all the mirrors.
Other changes and fixes.
The day of the week is now available on the website.
Fixed the RSS feed to show explicit status.
Fixed a bug that limited the future feed to just 10 shows.
Fixed a typo in the status page.
Following feedback, added emphasis about the upcoming two weeks, to
the scheduling guidelines.
Notable shout out to the people who are promoting HPR and are
helping people out with audio issues.
This is a look at the early history of science fiction, focusing on
the Golden Age, which is roughly the decade from 1939-1950. This is when
many of the great authors developed their craft and became famous, and
in turn set the ground for science fiction going forward.
Today I want to talk about why digitizing analog photos.
Three years ago, I wrote a chapter in the annual book for a home
village association. The chapter was about life in a small village in
the 1930's. In addition to the text I had a couple of black and white
photo prints from those days.
I said black and white. But honestly, an eighty year old black and
white print is not only black and white. Because of aging, type of paper
and development method, the black and white print has colours. Should
the photos in the book chapter be of best black and white photo quality,
or should they reflect the prints as they are at the time of the book
release?
There is no right or wrong answer into that question. But it relates
to the topic, why digitize?
I have found the web site "Preserving history. How to Digitally
Archive and Share Historical Photographs, Documents, and Audio
Recordings".
The main focus is photographs, but as the title states it is also
about documents and audio. The web site is written and organized as a
book and is a very comprehensive and useful resource. It is a few years
old but is still to a large extent accurate and relevant. The exact
details, which equipment, formats, settings and so on can be discussed.
And as technology has evolved, what the book describes as best has to
some extent changed so the best practise can now in some cases be seen
as good practise.
The book has a chapter titled "Historical Archive Versus Personal
Photograph Collection".
The historical archive is about to preserve the object in every
detail, e.g. colours, scratches, borders and dimensions. It is
applicable for true archives, like museums and other public
archives.
The other reason to digitize is of personal and family reasons. In
this scope, the focus is to have good photos. This approach gives better
flexibility in method, equipment and settings, and in general the work
will probably be less time consuming.
So the take away from this episode is that I recommend you to give
the purpose of why you digitize photos a thought before you start a big
digitizing project. And that you need to balance any desire to make the
best possible archival copy with the best possible equipment and all
time in the world with what is realistic for you, and what is good
enough. And at the other end, the happiness to have and share a digital
photo copy of any quality is better than none at all, but considering a
bit more of work and attention may improve the quality
significantly.
Finally, I also want to give a few remarks to my own episode number
4244.
I talked about placing the negative or positive in direct contact to
glass under or above it. Be observant, there is a risk this will create
Newton rings which can affect the result in a not acceptable way.
The problem that the object is not totally flat in a flat bed scanner
should in most cases not be a problem because the scanners are normally
designed to manage a bit of focus depth.
Remarks on my repro setup:
My digital camera is mounted on a repro stand. The stand is similar
to the stand used in an analog darkroom.
The "duplication direction" is opposite to the analog darkroom: The
camera is mounted on the stand, while the object to be duplicated is
placed on the base plate.
I have a light table on the base plate when a negative or positive is
duplicated.
Mounted on the camera, depending on lens, may an extension tube be
needed to achieve the macro distance to duplicate a small object.
