+
+project goals / philosophy
+
+* inverse linux philosophy -- do all the things, and do an *okay* job
+  * quick drop-in service to get a lot of features in a pinch
+  * there are probably [better alternatives](https://github.com/awesome-selfhosted/awesome-selfhosted) if you have specific/long-term needs
+* run anywhere, support everything
+  * as many web-browsers and python versions as possible
+    * every browser should at least be able to browse, download, upload files
+    * be a good emergency solution for transferring stuff between ancient boxes
+  * minimal dependencies
+    * but optional dependencies adding bonus-features are ok
+    * everything being plaintext makes it possible to proofread for malicious code
+  * no preparations / setup necessary, just run the sfx (which is also plaintext)
+* adaptable, malleable, hackable
+  * no build steps; modify the js/python without needing node.js or anything like that
+
+
+## future plans
+
+some improvement ideas
+
+* the JS is a mess -- a preact rewrite would be nice
+  * preferably without build dependencies like webpack/babel/node.js, maybe a python thing to assemble js files into main.js
+  * good excuse to look at using virtual lists (browsers start to struggle when folders contain over 5000 files)
+* the UX is a mess -- a proper design would be nice
+  * very organic (much like the python/js), everything was an afterthought
+  * true for both the layout and the visual flair
+  * something like the tron board-room ui (or most other hollywood ones, like ironman) would be :100:
+* some of the python files are way too big
+  * `up2k.py` ended up doing all the file indexing / db management
+  * `httpcli.py` should be separated into modules in general

+file indexing relies on two database tables, the up2k filetree (`-e2d`) and the metadata tags (`-e2t`), stored in `.hist/up2k.db`. Configuration can be done through arguments, volume flags, or a mix of both.

 note:

  * server writes chunks into place based on the hash
 * client does another handshake with the hashlist; server replies with OK or a list of chunks to reupload

+up2k has saved a few uploads from becoming corrupted in-transfer already; caught an android phone on wifi redhanded in wireshark with a bitflip, however bup with https would *probably* have noticed as well (thanks to tls also functioning as an integrity check)
+
+
+## why chunk-hashes
+
+a single sha512 would be better, right?
+
+this is due to `crypto.subtle` not providing a streaming api (or the option to seed the sha512 hasher with a starting hash)
+
+as a result, the hashes are much less useful than they could have been (search the server by sha512, provide the sha512 in the response http headers, ...)

+hashwasm would solve the streaming issue but reduces hashing speed for sha512 (xxh128 does 6 GiB/s), and it would make old browsers and [iphones](https://bugs.webkit.org/show_bug.cgi?id=228552) unsupported
