| marcoagpinto | lotuspsychje: I am about to leave to bed soon | 03:43 |
| marcoagpinto | I have been coding and working on LanguageTool | 03:43 |
| marcoagpinto | :) | 03:43 |
| marcoagpinto | and cola!!!!! | 03:44 |
| Maik | guiverc: no problem | 06:07 |
| lordievader | Good morning | 06:09 |
| guiverc | :) | 06:11 |
| ducasse | good morning | 06:16 |
| TJ- | at last, Starlink receiver is in its way (to the wrong address!!) | 20:31 |
| sarnold | finally, someone else will be free of the monopolies! | 20:32 |
| TJ- | not that; just free from being tied to > 2km of copper! | 20:37 |
| TJ- | irony though that Starlink have the delivery address wrong, corrected it late, and looks like they're sending me two receivers... I just have to persuade DHL to correct the 1st address :D | 20:37 |
| TJ- | So sat outside now configuring the network in preparation for it | 20:38 |
| TJ- | hmmm, does this sound correct when doing a simple package upgrade "After this operation, 5,108 kB of additional disk space will be used" ... surely no additional, since it'll be that less the space the current package versions are using | 20:40 |
| sarnold | apt should be able to compare the installed size of the current package vs the new size of the new package in the lists and compute it that way | 20:46 |
| sarnold | it might actually reprepsent five megabytes extra space used | 20:47 |
| TJ- | oh doh! I read it as 5,109 MiB aka 5GB :) | 20:53 |
| daftykins | TJ-: have you not bribed someone to hook up the farm to a decent service? :D | 20:53 |
| TJ- | running it on a space-limited headless device | 20:53 |
| sarnold | TJ-: ah :) even five megabytes seems a bit larger than I'd expect most updates to do, but it certainly doesn't seem five gigabytes suspicious :) | 20:55 |
| TJ- | daftykins: I had hoped that when the UK minimum service requirement of at least 10Mbps came in 18 months ago that OpenReach would be forced to install a P2P wireless link... but instead they reduced the VDSL minimum SNR to less than 3db ... so it reports a sync rate > 10Mbps incoming but throughput is worse due to retransmits | 20:55 |
| TJ- | sarnold: yeah - this is an embedded device on 18.04 that hasn't been online in a year | 20:56 |
| daftykins | >_< | 20:56 |
| sarnold | TJ-: oh! so it'll be a hundred little updates instead | 20:56 |
| TJ- | and on VDSL now latency is all over the place due to the retransmits | 20:56 |
| daftykins | TJ-: just got the VDSL2 turned on today at a client's new place, MSAN next door - line sync of 115 down, 55 up | 20:56 |
| TJ- | sarnold: 252 little upgrades | 20:56 |
| TJ- | daftykins: yeah; my only option was dig a fibre in to the farm... probably cost about £40k | 20:57 |
| daftykins | you know you want to ;) then you can earn it back by being a WISP to your neighbours! | 20:57 |
| leftyfb | damn, I couldn't deal | 20:58 |
| TJ- | at the office with fibre we way £380~ per month for 100/100/7ms ... Starlink will give something like 150/30/16-30ms for £89 per month | 20:58 |
| TJ- | daftykins: did explore that but not enough neighbours | 20:59 |
| TJ- | s/way/pay/ | 20:59 |
| daftykins | aww :( | 20:59 |
| TJ- | and unlike fibre Starlink can be moved | 21:00 |
| daftykins | and those wild backhoes that roam the lands can't dig through it! | 21:00 |
| daftykins | think i'd still prefer it though :D | 21:00 |
| TJ- | I can mount Starlink on a trailer and take it to outdoor shows and so on, once they permit relocation/roaming | 21:02 |
| TJ- | right now they need to know which 'cell' the receiver is in for scheduling/load planning of the satellites | 21:02 |
| jeremy31 | The orbit of those sats is about 50 miles higher than the ISS | 21:15 |
| TJ- | 550km | 21:15 |
| jeremy31 | Doppler must be figured into the receivers | 21:16 |
| TJ- | they used phased arrays for beam forming and steering too | 21:16 |
| jeremy31 | At that altitude one sat would go from horizon to horizon in about 12 minutes | 21:18 |
| TJ- | there's some great animated real-time trackers | 21:18 |
| jeremy31 | Yes, I used some when I was using amateur radio sats | 21:20 |
| jeremy31 | I think the google play store had one where you could point your android device at the sky and see what sats were there | 21:21 |
| TJ- | yes, i used that a lot | 21:26 |
| TJ- | the best Starlink tracker in terms of visuals and info is https://starlink.sx/ | 21:27 |
| TJ- | shows the ground station gateways and distances from the satellites which gives some indication of expected latencies | 21:27 |
| daftykins | very neat | 21:30 |
| jeremy31 | It will definitely be many times less latency than existing sat service as latency must be at least half to 3/4 of a second | 21:31 |
| TJ- | for geo-synchronous, yeah. 550km vs 35,700km | 21:33 |
| TJ- | and once the newer satellites with laser links are operational latencies will drop further | 21:34 |
| jeremy31 | Tin foil hat time | 21:38 |
| daftykins | xD | 21:39 |
| jeremy31 | The lasers will fry your brains | 21:40 |
| daftykins | if the 5G doesn't get you first! | 21:40 |
| jeremy31 | I work with people that have nothing to worry about | 21:40 |
| TJ- | it may improve some! | 21:43 |
| jeremy31 | There might be hope | 21:44 |
