We just published the jpylyzer 2 release candidate, which includes (among other things) support for raw codestream validation. More info here: openpreservation.org/news/jpyl

Here's a weird and slightly spooky 1-minute trailer(!) I made for the upcoming jpylyzer 2.0.0 release (don't miss out on the audio on this one) youtu.be/gIutpFxGy28

Here's a video of the presentation I did on recovering '90s data tapes at (audio is not from the actual presentation, but from a rehearsal I did a day earlier) vimeo.com/362061955

Recovering '90s Data Tapes - Experiences From the KB Web Archaeology project bitsgalore.org/2019/09/09/reco Web-friendly version of the paper I wrote for the upcoming conference in Amsterdam. Contains links to lots of tape-related resources

Attention jpylyzer users - I'm considering some changes to jpylyzer's output format for an upcoming 2.0 release in November. See this note for details: gist.github.com/bitsgalore/300 If you have any comments or suggestions just let me know!

One for the floppy crowd - a simple disk imaging workflow tool (basically a simple graphical front-end around dd and ddrescue) bitsgalore.org/2019/04/10/a-si

UPDATE: OPF call was this morning, and codestream validation in jpylyzer will happen! github.com/openpreserve/jpylyz (already did a quick test last week which confirmed this is easy to implement)

An email I got yesterday about validating JPEG 2000-encoded video frames made me think about adding an option to jpylyzer for validating raw JPEG 2000 codestreams (through the Python API and the CLI). Is this something anyone would find useful? (Next week there'll be a call with OPF about the priorities for an upcoming jpylyzer release by the end of 2019, so if this is something people are interested let me know so I can try to push it up the priority list!)

Working on a lecture for next week inspired me to properly condense all my bookmarked emulation resources into one basket, and put the list out there for everyone.

If you've got favored blogs/papers/guides for emulation, please contribute and share!!


Following a couple of days of digging, dusting and editing, restored versions of all preservation-themed blogs I've written since 2010 are now available here bitsgalore.org/ Will probably use this as my main blogging platform from now on.

Wrote a new blog post on recovering ’90s data tapes, with links to full workflow descriptions (including hardware configuration), easy to use recovery software and tonnes of other tape-related resources openpreservation.org/blog/2019

Out now: new release of the tapeimgr tape extraction tool. Now with improved metadata support (incl entry of identifiers, descriptions and annotations through GUI or CLI). Default output dir is now configurable as well github.com/KBNLresearch/tapeim

New tool klaxon red alert! First public pre-release of tapeimgr, a simple tape imaging and extraction tool (GUI + CLI). Details here: github.com/KBNLresearch/tapeim

Python-based tape extraction tool (GUI + CLI) is shaping up nicely (code will follow once I've sorted out some remaining details) ....
