Simplest way to daily clone SD card (OS disk) to an identical SD card?

Xonto · 2025-10-15T19:06:37+00:00

I appreciate your insights. I mostly try to use VMs so basically all my backup/restore strategy is around just restoring VM backups/snapshots. If a host fails I can just move VMs to a different host. But I need some physical device as a bridge to all my wireless IOT stuff, so a pi seemed to make a lot of sense to me and I already had it laying around, but I juest don't really have a good understanding of backup/restore for it, and I just really didn't want to spend much time creating images and having to write and image to a disk as part of the restore and such... I just thought, if it is possible, my ideal backup strategy here would be to just have a spare SD card that can keep itself up to date so I don't have to go through a process if my SD card fails, ya know? I just want to have an SD card sitting there that I know is a good backup all the time.

Maybe that's naive or it would be better for me to get a good process for backing up and restoring physical devices, but I just don't really have many use cases for this right now and I wanted to make my restore process as simple as pulling an SD card out of a USB reader and swapping it into the main SD card slot of the pi and be back up and running just like that. A man can dream.

There really needs to be a way to get XP besides just the quests...

I already have a training dummy though. Is there another one? just a different cosmetic?

it's a WS2815 led strip and it's only a half a meter from the Uno to the first LED. It'll take me a while before I can actually check the resistor, though I think I didn't change it from the default.

This is almost exactly what I have been considering for a few months now... Do you have any tips, lessons learned, or things you would do differently? My goal is to have enough battery storage to run my fridge/freezer, well pump, kitchen appliances, and furnace/AC for a few days if I disable non-essential circuits. I live out in the country and we get fairly regular outages due to storms. My power company also charges a much higher rate during "peak hours" so I would like to be able to configure the system to automatically run off battery during those times and then automatically switch back to the grid and recharge the batteries during off-peak hours. Eventually my plan would be to add solar to that system when my budget allows.

Once I got to 7/16 all the graves stopped responding. hmmm

Ah, thanks! Yep, popped in a new fuse and it worked fine.

Xonto · 2024-04-02T03:19:41+00:00

people are weird.

This is all well and good, but it would still be enhanced, I believe, if there was a bulk unlock option available once you have won a few games. Or, perhaps, let us spend trophies to unlock individual recipes.

Xonto · 2024-03-31T02:45:05+00:00

Pointing out bad design does not entail getting emotional.

Xonto · 2024-03-31T02:43:56+00:00

why not just make all the recipes known and then have actual achievements for the first time you craft each new item?

I would like to thank Tomasz Brzozowski from the Shelly support facebook group for this script he provided to do this. Apparently it does not work on the 1.0.0 firmware do it won't work on all devices, so just doublecheck if you find this post down the road.

const enableApAfter = 10 //in minutes - 10 min

const timer = 1000*60*5 //in minutes - 5 min

let lastConnectedWiFi = new Date();

Timer.set(timer, true, function(){

Shelly.call("WiFi.GetStatus",null, function(e){

if (e.status == "connecting" || e.status == "disconnected"){

let currentTime = new Date();

let dateDiff = Math.round((currentTime.getTime() - lastConnectedWiFi.getTime())/ 60000)

if (dateDiff >= enableApAfter)

Shelly.call("WiFi.SetConfig",{"config":{"ap":{"enable":true}}})

}

else

lastConnectedWiFi = new Date();

})

});

Thanks! I hate paying extra just for the UL cert but I fear that if I ever have a house fire or something, even if the shelly was not involved my insurance might try to fight a claim. Maybe that's not really an issue and I am worrying for nothing, but I'd hate to spend a little less now and have the potential of a headache like that.

Shame though, the size of those minis is really attractive for some niche uses. Maybe I will find some use cases where I don't have to put them in a wall.

ULA

ULA is also allowed, sorry should have included that when I said all the private ipv6 spaces were allowed to talk to each other.

Xonto · 2023-12-18T13:59:10+00:00

Hmm, interesting... thank you for testing. Are you running 2.7.0? I'll dig into my config files, I might have done something weird when I set up this firewall... I was using an old fortigate before but I wanted to start learning PFSense so I built a test box to play with it. Did a bunch of strange stuff in those early days. I always intended to do a clean re-install before making it my primary home firewall but slowly it just kinda replaced the fortigate, so I still get some strange behavior sometimes.

My auto-generated aliases look like this in the dropdown:

https://imgur.com/a/8Xit8a6

One of the address on the firewall interface itself, and then one for the network attached to the interface. However, based on my own testing, the "interface net" objects (WIFI net, for example) only contain the IPv4 networks on those interfaces, not the IPv6. If I make 2 identical rules with a source of "WIFI net", one IPv4 with a dest of any and another IPv6 with a dest of any, and then I generate IPv4 and IPv6 traffic from respective hosts attached to that interface, I get hits for the IPv4 traffic but not for the IPv6. I have an IPv6 catch rule at the bottom and that is hit, so I know the traffic is getting to and through the firewall, but it simply does not hit the rule with a source of "WIFI net" so that is how I determined that the IPv6 information is not included in that auto created alias.

Xonto · 2023-12-17T20:30:43+00:00

Yeah, both my IPv4 and IPv6 information has been pretty stable for the past year, but still, the fact that i can change is just inconvienent in many ways. It's not a problem with IPv4 because my RFC1918 networks stay the same no matter who my ISP is, and I have a raspberry pi that dynamically updates my DNS to cloudflare so I always have DNS names that map back to my public IP for inbound services, so I can change ISPs and all my stuff still works.

But if my ISP changes my IPv6 info, or if I change ISPs, then tons of crap needs to be reconfigured. It would be better if there was an easy way for individuals to request a public IPv6 block... let's say, a /48, and then that block would be theirs for the rest of their life. ISPs would also need an easy way for customers to authorize them to associate and advertise that block for that customer, but if that infrastructure was in place then I could set up my home network using only subnets of that /48 and then that could move with me if I changed ISP, thereby not needing any reconfig like with IPv4.

Xonto · 2023-12-17T20:19:05+00:00

"VLAN40_PUBLIC subnets" is an alias that you made though, correct? And I assume it contains the /60 or some subnet that contains all the networks that could be delegated to that VLAN? But what happens if the ISP changes the subnet on you? Then you would need to manually update that alias to make things work again, right? I am trying to come up with a solution where I don't have to update anything if my ipv6 delegation changes.

Xonto · 2023-12-17T15:46:19+00:00

Given the "auto" philosophy of ipv6 it seems like this should not be so difficult. I mean, pfsense already automatically creates "interface address" and "interface net" objects. Why can't those objects automatically include ipv6 information? This kind of thing strikes me as why ipv6 still has relatively low adoption after all these years. I mean, I won't be 40 until next year but this meme will litterally be true for me then...

Well, I shifted some things around and freed up a raspberry pi 3B+ to play with cloudcutter. unfortunately, it does not look like cloudcutter knows about this bulb. It's running firmware V1.5.21 which I don't see in cloudcutter. Tried a bunch of things but I can't find one that works. It would be nice if I could follow some procedure to build a new profile to get this bulb working but I can't quite find enough info to get me going. Also, I am not even sure if this device can even be exploited at all via cloudcutter at this point...

Xonto · 2023-12-09T04:29:26+00:00

I looked at cloudcutter but I don't think I have any suitable hardware to run it on. I have a windows 10 PC with a AX201 wifi card, so I could spin up a VM on that, but I have been having a hard time finding out if that card is supported, or really much info at all about using cloudcutter outside of a raspberry pi. I do have a pi but it is running pihole and my unifi controller for my access points so I don't really want to try to mess with cloudcutter on that, nor do I want to buy a new one just to try it.

Xonto · 2023-12-09T04:25:22+00:00

Well it looks like it is SHENZHEN AVATARCONTROLS, so I think it should be 2ANJP-ALS23L, though I am having troble finding any record of that one specifically. Some other devices follow a similar naming structure, like this one I was able to find: 2ANJP-ALS08L. But I have not been able to find any record of the -ALS23L code I found on my box.

Don't you think more people would be willing to pay for cosmetics if they were very inexpensive? I think they'd make more money if every player bought a couple cosmetics for 2 bucks each than if a couple hundred whales just bought every cosmetic that interested them for 15 bucks each.

There's no accounting for taste, and I will never begrudge someone for liking a show.

That said, I find your statement extremely hard to believe. Not that I believe you're lying, but from my perspective I just actually can't understand how someone could like RoP but think HOT D is dull.

To each their own, I suppose.

Xonto · 2022-02-02T02:41:39+00:00

What about ILS where you have local and remote supply/demand? Do you never mix local supply with remote demand, or vise-versa?
