We have basically no cellular connectivity or internet access at our new home.
We will in the near future have a slightly better (but still slow) 4g connection thanks to our cell site booster, and DSL (about two miles from the DSLAM.)
I have invested a lot of time and energy in to offline first applications, but not in a while, so I'm re-investigating these things specifically as they relate to our new housing situation.
One tool that I have played with in the past is Kiwix.
Kiwix is an offline wikipedia reader, and it's pretty useful, especially when paired with Kiwix serve.
It seems like you should be able to abstract it in to a full fledged LAN to internet bridge, leveraging RSS support and maybe a couple of hacky hotsync jobs to download content when you have a network connection and then sync it with your LAN machine when you're on your LAN.
This doesn't work, though.
It has a few pretty severe limitations that relegate it to the world of Just Wikipedia, and not more generally useful for me, and I always forget about that until I try to build my own content for it.
Basically, it uses the file format from zim-wiki, a desktop wiki tool. It's really not great at serving content from multiple websites at one time (I can make it work, but it's needlessly complicated) and building content for it is an absolute nightmare.
So I'm looking for something better.
I want to cobble together a LAN internet in a box.
Something like the piratebox project, but that enables me to sync in content from outside my network.
I have some options.
Dat/Beaker always looks like it would be a solution to this problem, but it's node based and the last time I used it the command line functionality was limited. I'll re-investigate it.
More importantly Dat only solves the *sync*, not the capture or the serve.
Which brings me to the reason I started this thread in the first place:
What are your favorite LAN-first or offline first applications for desktops, servers, and mobile devices?
I would prefer to hear about applications with which you have firsthand experience, but I also wanna know about cool stuff that you've just heard about in passing.
Assume storage is free, assume local bandwidth is very high, assume that internet access is unavailable most of the time, but occasionally Very Fast.
@elb @ajroach42 Oh yes, I can jump in. So, start with #Syncthing. I love it. I explored some possibilities with it at https://changelog.complete.org/archives/10219-a-simple-delay-tolerant-offline-capable-mesh-network-with-syncthing-optional-nncp . Syncthing is serverless sync, ala Dropbox, but also distributed. One possible scenario: a device (laptop or phone) is the "carrier". Syncs locally at the house, and to someplace on the Internet at a coffee shop / in town / whatever.
@elb @ajroach42 4/ What you are really after is more general asynchronous communication. I have a whole blog series about this, including #NNCP and other tools: https://changelog.complete.org/archives/tag/asynchronous will give you all the posts in the series. Many of them are somewhat focused on backups, but should give you some good ideas for other things also. NNCP can use things like USB sticks, serial links, regular Internet connections, Syncthing, etc. as transport.
@elb @ajroach42 6/ You talked about accessing web pages offline. I've tried that but mostly don't really bother. It is fairly painful (you frequently want to click on a link you don't have). In some cases, for things like larger articles, it can make good sense. But you might want to look into something more like rss2email . Email is already asynchronous and there are lots of ways to get asyncrhonous email across. NNCP is one and documents this workflow at http://www.nncpgo.org/Feeds.html
@elb @ajroach42 7/ Offline email is two separate problems: sending and receiving. Sending can go across BSMTP (delivered "somehow" via NNCP, UUCP, Syncthing, etc). I talk about Exim with NNCP as part of my series here https://changelog.complete.org/archives/10165-asynchronous-email-exim-over-nncp-or-uucp and the NNCP docs go over the Postfix setup. For incoming, you can use OfflineIMAP or an offline-capable mail reader. Alternatively, forwarding to an account you can receive via NNCP/etc to a local mailstore.
@elb @ajroach42 9/ Finally the two best ways to improve your 4G signal are: 1) height, and 2) antenna. I got one of these https://smile.amazon.com/gp/product/B01NBSLNJ6 with a Nighthawk M1 awhile back. Tremendous difference. A booster can only boost what it can receive. A good antenna, mounted high, hardwired into the access point will almost certainly be better. That antenna has "gain", meaning it's directional, so figure out where your best towers are and point it at those.
