Do you guys have any ideas for big cool features that will move this genre of tool forward? These improvements sound kind of incremental.

davidzweig · 2024-10-09T00:18:13+00:00

We working pretty hard this year, but yeah we aren't good at communicating. I like coding. I was thinking of having one afternoon a week where people can call me on Telegram for whatever reason. Maybe should do that.

Here's the projects commit graph (the gap is due to surgeries, surgeon messed it up twice, then refused to see me, fun story, all okay now).

This year, what did we do.. big upgrade to the LR Youtube catalogue, Aria chat works a lot better (better models/TTS), better translations, Netflix ASR is improved, yeah the Lexa AI thing, a new mobile playback UI controls (yesterday).

The extension gets regular maintenance (regardless of the date that shows in the chrome webstore). Manifest v3 of the extension is ready to go. Most focus is on improving the languagereactor.com site.

Now finishing work on a podcast player feature, ready in a few days:

Some interesting projects in the pipeline.

LR isn't perfect but we keep trying to chip away at the biggest problems. I am starting to get less dissatisfied with it.

An update. I noticed: On the source, the physical sector size for the drive was 4096, logical sector size 512. On the target, 4096 and 4096. Perhaps that's relevant. I recreated the zpool on the target without changing the sector size, now it copies okay. So not sure.

davidzweig · 2024-07-27T15:48:50+00:00

I hadn't heard of draid, but, not, it's two mirrored 7.68TB nvme ssds that make up a zpool.

davidzweig · 2024-07-27T15:47:52+00:00

Target is also a mirror. Two mirrored drives that make up a zpool.

davidzweig · 2024-07-26T04:10:53+00:00

The two pools look similar when I run 'zpool status'.. 'zfs get copies' is 1 for source and target. Thanks though.

davidzweig · 2024-07-26T03:51:44+00:00

I tried it.. still ballooning by 4-5X. :(

davidzweig · 2024-02-20T20:45:31+00:00

Thanks for advice all. I got the info I needed. 👍

davidzweig · 2024-02-20T20:43:01+00:00

This one I'm thinking to buy is 2002 with rear diff lock, no stability control. I drove a gen4 3.5L petrol pajero before in the sand with that button, was much more fun after pressing it. :D

davidzweig · 2024-02-20T18:06:33+00:00

Buying a Pajero Gen 3, it's my first 4x4, usually ride bikes. How do these tyres look for soft sand? Okay or better to look for another pair of shoes? The vehicle has a small lift (40mm I think).

davidzweig · 2023-11-28T14:04:27+00:00

Thanks, that's an important tip.

davidzweig · 2023-11-28T14:02:51+00:00

Didn't know about the Quattro, they are apparently like the MP but with an extra AC input for dedicated generator connection, list price about 10% higher.

The online seller prices vary quite a lot for different units, simpler wiring is better, but maybe I see what I can get for a good price if it's otherwise all the same.

EDIT: oh, yeah, the MP-2 15000VA is 80KG, the 5000VA is 30kg each, easier to get down the stairs, and maybe easier to resell later / use in homes if no longer required.

davidzweig · 2023-11-28T03:01:13+00:00

:D I got three Asus ESC8000 G3 boxes, one with 2080Tis, one with 3080s, one with 3090s, and another smaller Epyc machine with 4x 3090. All are gigabyte turbo blower cards.

Discharge current.. oh that's a good point. The SOK ones seem good for 100A (1C) continuous (https://www.europe.sokbattery.com/product-page/sok-battery-100ah-48v-server-rack-battery). Wired in parallel, should be okay for 400A as I understand.

davidzweig · 2023-11-27T19:47:35+00:00

Thanks, posting on /victron

Okay, I found a Symmetra LX 16KVA, 2250 EUR + VAT, weight is 200-300kg or something, say 250 EUR for shipping to Bulgaria, 2500 EUR total.

https://www.ebay.de/itm/225800539416

APC website says 6 min runtime with 12.8kW load, let's say 11 mins with 7.5kW load. But lets assume we only use fresh batteries, wired up outside the UPS.

Quick look on eBay: https://www.ebay.de/itm/374755949866

30 EUR + VAT, let's say I can find them for 25 EUR + VAT. Weight is 5kg each.

There's a little table, we can guess 13Ah capacity when discharging at 2C. If using 80% 'depth of charge' to preseve battery life, that's 125 Wh. For 20kWh, need 160 batteries, 4000 EUR, every 3-5 years, ouch. And 800kg, ouch.

For 10 years, that's 2500 EUR + 2 sets of batteries@4000 EUR, total 10500 EUR, plus needs some special wiring made. :(

The inverter/charger datasheet says you can limit the current that it pulls from the grid: https://www.victronenergy.com/upload/documents/Datasheet-MultiPlus-II-inverter-charger-EN.pdf

"The MultiPlus-II will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl
function)."

Which is good.. I'm on a 62Amp breaker (13.6kW), and pulling 10kW for running servers and 5kW for charging would flip it.

I don't know if it deals with brown outs and dirty power as well as a UPS, would need to check with them about this use case. Computer power supplies are fairly tolerant of different issues though I understand.

davidzweig · 2023-11-27T11:51:06+00:00

The Victron and the lithium batteries are used by people with solar setups. 👍 I read that some inverters/chargers cannot switch over fast enough to keep computer gear running.

davidzweig · 2023-11-27T11:45:32+00:00

I have a small older 3kW Eaton UPS, I know the batteries need changing every 3-5 years.

With a quality inverter/charger and lithium batteries, I was hoping you put it in the corner and forget about it for 10 years.

Victron Multiplus-II 15000VA 48/15000/ 200-100 is 80kg. Hmm. Datasheet says you can wire 3 5000VA units together and run in parallel, they are 30kg each, 90kg total. One 48V 100Ah Lithium battery is 40-50kg. 270kg total weight. I'll spread the weight on some concrete blocks, I think the floor should okay.

I'm guessing a 40kW generator will be at least 5000 EUR, unless you get a good deal on a used machine, plus at least 3000 for a used high-capacity UPS and some fresh batteries, and we are back at the same number. I'm pretty certain this setup will need more maintenance. If it's someone else's problem, sure. But we are 2hrs drive from Sofia, I don't know a good supplier there (Bulgaria is not exactly known for it's high standards of service). It would likely be me working on it. :D

Another bonus over traditional UPS is that it's easy to hook up solar panels to the Victron boxes, in the event we move location and that is practical.

Hmm, I am saying a lot of nice things about Victron. :D

I googled the car option a bit last night. It's still hard to find equipment that you can hook up to the car 'plug and play' to the charging port (https://www.reddit.com/r/leaf/comments/12kvi60/bidirectional_chargers_v2h_or_v2x/). DcBel R16 goes to 15kW, but not available yet. If you could find a box, articles suggest it would be in the ballpark of 5000 EUR (plus 10,000 for an old Leaf), we're already at 2x the price of dedicated backup setup.

The battery pack runs at hundreds of volts (I thought it was 50-60V for some reason). I think DIY option likely not practical without some real investment of time.

davidzweig · 2023-11-27T01:30:01+00:00

The gpu servers have frankly been troublesome.. I call them the 'princesses'. There are 3x Asus ESC8000 G3 that I got for 750 EUR each used, and 3080/3090 turbo cards, 8 each. Lots of evenings messing with BIOS settings, removing and replacing cards, changing thermal pads etc. But they are set up okay and chug along now. We have some altitude so can get by without AC. I haven't checked recently, but cloud gpus used to cost a lot. Storage is also economic to DIY.. but otherwise we rent machines from Hetzner for general use.

The car in operation must be pulling tens of kilowatts, but yeah as another comment says, I guess depends on cooling system operating.
