@lavaeolus For me personally, preserving a copy of the underlying dataset is priority number 1, because at least you have half a chance of reconstructing something from that. Then the source code of the site, which can either be used directly or at least give insight into the logic. The latter is definitely one for @swheritage

Neither of those captures the lived experience of using a web application though, which can be important in some instances.

Question re #SafeguardingResearch
We encounter 'web applications' that our current method of archiving don't preserve.

Things like [we need a better example, this one is already gone (but the data preserved) social.coop/@edsu/114206452552]

We are mostly using github.com/openzim/zimit to create WARC files and combining them into a single ZIM.
(This uses the browsertrix crawler)

Any ideas on how to archive not just the content, but also the functionality of such applications?

social.coopEd Summers (@edsu@social.coop)@anj@digipres.club @lavaeolus@fedihum.org @ww@tldr.nettime.org the dashboard API calls are going to URLs like: https://awsgov-api.imls.gov/api/column/0/2024/null/county?_=1742650522892 Which seem to return no results. It's interesting that even though the dashboard doesn't seem to work in the browser you can find lots of the JSON responses in the Wayback Machine which are there due to some SavePageNow & GPO Archive-It crawling? https://web.archive.org/web/*/https://awsgov-api.imls.gov/api/* In fact some of the links still seem to work, which suggests that the dashboard interface is broken (intentionally or by accident?)

Next, I compared the good and bad files in Hex Fiend. The good ones had an "lh1" signature in the header, while the bad ones had an "lh5."

Okay, clearly they were using different compression methods. But how could I extract the lh5 ones?

Googling turned up this Keka issue on GitHub --
github.com/aonez/Keka/issues/1 -- which mentions a different problematic Atari ST LZH file on Discmaster and how dexvert handles it fine.

Another odd LZH, from Atari ST http://discmaster.textfiles.com/file/11869/www.umich.edu.archive.2014.03.zip/www.umich.edu/~archive/atari/Games/Puzzle/nanjin11.lzh Originally posted by @gingerbeardm...

Interesting discovery today ... Came across a cache of 20 issues of "Express Times", an electronic newsletter for sysops running BBS Express! ST software on the Atari ST.

But all 20 issues were .LZH archives. I tried to open them on my Mac using Keka, but only about half of them worked.

So I booted Hatari and used UNLZH, but it also began throwing CRC errors for several files.

Ok #avpres question. We recently digitized an old umatic tape with a documentary on it. Only one audio stream in stereo with the left side being English and right side being Vietnamese. Currently the MKV only has English for the audio stream. Without splitting the audio stream into two, what is the best way to manage the technical metadata? #digipres

David Rosenthal has written up a fantastic blog post from a talk he did on the current state of archival storage - the tech, the pros, the cons, and more. I also like that he points out that archival storage is NOT the same as a data backup, because it might be easy to conflate the two. The post is well worth a read.
(Thank you to a few people who have shared this around!)

This afternoon the failure notices have been rolling in for a series of GitHub actions that I've set up to automatically capture data about Trove. As well as powering things like the Newspaper Data Dashboard, these harvests were part of my attempt to capture the development of online GLAM collections so that future researchers would be able to examine their impact. I talk about that here: updates.timsherratt.org/2024/0

But because the NLA has cancelled my API keys, these harvests will not run, and the sequence of harvests will be broken, perhaps forever. #GLAM #digiPres

updates.timsherratt.org · Preserving the history of online collections (my love letter to future historians)It’s pretty obvious that access to digitised resources, like Trove’s newspapers, has changed the practice of history in Australia. But how? I’m certain that the historiographical implications of the growth and development of online collections will become a topic of increasing interest to historians, and that exploration of this topic will lead to important insights into the relationship between what we keep, what we value, and what we know. But for this to happen we need to have data documenting changes in online collections.

digital preservation and archivist friends: it came to my attention recently that mobygames was bought by some trashy atari holding corporation a few years ago. all of the scans and item entries that many of us slaved over for the past 25 years were sold off. anyone submitting mobygames entries/updates are effectively working for free now.

i can't say i'm unhappy to see it going downhill with the new owners. updates to entries went from taking 1 day for approval from moderators, to 4-6 months.

it also had a frustrating limitation of declaring any software outside of its very traditional definition of game as out-of-scope.

that being said, it's a critical service for those researching and writing about games.

i'd like to know if there are any publicly-owned database initiatives in development to replace and/or subsume mobygames.

and if not, let's build one.

Over the last week, I've spent some time digging in to "Nosh Kosh," the Jewish Pac-Man clone for the Apple II that's all about kashrut — Jewish dietary law.

Along the way, I've run into bugs, mapped out level designs, and calculated checksums to figure out how many versions there are.

Check it out! Here's my presentation on rescuing the lost games made by Ya'akov Kirschen and Gesher for the Apple II. The talk was given at the Atlanta Historical Computing Society last fall.

I incorporated new things I learned during my research fellowship, exploring materials at Emory University and the Breman Museum.
