I'd sell my soul to have bundled html + css + images + assets in a zipped format.

Basically, modern web - all of javascript. Instead of using PDFs.

That'd be a banger way to create and distribute documents. Also very versatile and portable, cuz, like, websites lol. Prove me wrong.

EDIT: I reinvented sophisticated epubs. Wow.

“…as #MicrosoftWord took off in popularity and quickly established itself as the dominant word processor, we saw the rise of the .doc #fileformat. This was an exponential increase in complexity from what came before, which made sense because suddenly #wordprocessors were becoming "everything tools"—not just typing, but layout, images, revision tracking, embedded objects, and whatever else Microsoft could cram in there.”

Hello fedi!

I have an .MVAX #firmware #update file for an MV Silicon chip (unknown model).

Has someone already encountered those? And if yes, is there some documentation, tooling or existing #ReverseEngineering work done of that format?

For the record, the file magic (first 8 bytes) is as follow:
4D 56 B5 58 05 01 13 00

And the end of the file contains the following (no spaces, wrapping is mine):

MVSKeyFileMVBP10<0x90>0xBE>SIMPLEs
<0xD3><0x9A>.<0x90><0xD9>
MVSILICONKEYFL<0x00><0x00>
<0xFF><0xBD><0x00>0x00>

Thanks in advance for your help!!

Data centers are one of the biggest reasons for carbon emissions. 

Why can't we create new image, video, and other file formats that are more efficient for saving storage and power in data centers?

I released an update to my libE57Format library—version 3.3—to fix some build warnings & to update the build system (cmake)🏗️.

It is a C++ library which provides read & write support for the ASTM-standard E57 file format on Linux, macOS, and Windows. E57 files store 3D point cloud data, attributes associated with 3D point data (color & intensity), and 2D images (photos).

🚨 Alert! #Innovators at Cognition have heroically reinvented the wheel by creating yet another file format for VM disk snapshots, because, you know, existing ones just weren't cutting it. 🤦‍♂️ Meanwhile, the rest of us will keep sipping coffee, wondering what problem this actually solves, and if anyone outside their office will ever care. ☕️

Also in the #fileformat space, the TrID file format identification tool has gone python! What used to be a windows or online application, is now multi-platform. Thanks Marco! #digipres https://mark0.net/soft-trid-e.html 2/2

I am quite proud that I managed to embed the json file of the menus in the PDF for both the iOS and web version 🙈 Makes it super convenient to be able to have a nice PDF file that you can also import to edit! Also the app has a preview extension to render the native json format (.rmenu/ .relationshipmenu) as a PDF when opening it in files ☺️

@iammannyj I looked into #Joplin not too long ago. What dissuaded me most was their #proprietary #fileformat. I avoid #lockin whenever possible. That said, it’s an interesting write-up. #OpenSource
