Like others said, this is not a great idea.

Unlike most battery powered devices, a spring iron in active use needs real wattage to operate, probably comparable to a small chainsaw or leaf blower. Those also just eat batteries.

The best recommendation is to just use a modern digital iron (see examples mentioned in other post) with a normal ac adapter. Just bring a compatible battery bank, or make a cable for whatever brand of tool batteries you have (18-20V preferred). If you are into RC models of any kind (drones, cars, planes) and that’s the reason you need it to be mobile, you have LiPos and you can just use those (xt60 onto a suitable cable).

The only downside is that there’s still a cable between the soldering iron and the battery, but honestly it’s fine, arguably even better as your iron isn’t huge, heavy.

You misunderstood my point. LocalSend is great. It does exactly what it promises, and works well.

But you’re claiming “AirDrop = LocalSend” and that is not true and causes false expectations. People used to Apple think they can use it in all the same situations and for the same things, which they can’t. Just because you mostly used it in the game network doesn’t mean most people use AirDrop that eat, and I know quite a few that mostly use it while out and about, meeting new people etc.

The “Good advice” version is too tell them there is LocalSend, which can do quite a few things like AirDrop, but not all. Basically make it clear they need to be on the same network.

This is such bad advice. If you tell people that, people expect it too work like AirDrop, which it doesn’t.

LocalSend is great, but it is much more limited than AirDrop. As the name suggest, it only works if people are in the same network. If you’re in your home network, and both devices are yours, that’s probably fair enough, but that isn’t the point or (only) use case of AirDrop.

Also if you’re installing it on a Linux machine which happens to have a firewall enabled by default, you will have to open the correct ports for it to to work out even just see the other devices.

In Firefox on Linux it’s a definitive “maybe”. It works on my gaming machine, not not on my home theatre PC. Same Linux install. Same configuration: Firefox with the user agent extension for Netflix, which was needed or it was stuck at 720p. HTPC is still stuck at 720p.

It’s all a matter of what you consider reasonable risk. I also run some specific services exposed where it makes sense (they are designed to do this, think things like home assistant or next cloud or jellyfin), but would never put anything that is used to do server administration public facing (Webmin, Termix, proxmox, that sort of thing). If the purpose of the tool is to perform or allow elevated actions, I run it behind a VPN (yes for me that includes ssh).

There’s also a difference between being randomly port scanned and/or probed, or being actively and personally targeted for some reason. If the second is ever a reasonable threat, that changes what is acceptable dramatically as well.

Yes, it inherently is. Authentication/encryption happens as the very first thing at the network level, before anything resembling a service becomes accessible. This is fundamentally different than for example a web interface, which needs to present “the Web page” to allow the user to log in, which might involve multiple individual parts that can already have a 0-day.

As a more direct comparison: look into historic vulnerabilities between ipsec VPN and SSL VPN. The former is the older technology, the second is more “web like”. The number of serious CVEs for the latter over just some manufacturers (Cisco, fortinet, …) in one year probably beats the number for ipsec in is entire life time.

My various servers, firewall and nas are relatively power optimized. Everything including switches (most with some 10g ports) and access points is 160 W or so. I can’t give you monthly usage, as I’ve got solar+battery so it’s frequently just 0 kWh for some days. It’s also rather hard to separate from the other power usage in the house when solar doesn’t fit cover it.

I have it. I didn’t finish a single playthrough since.

Not a single of their dlc has spoken to me or my play style. So a new game sounds great to me.
