- Comment on LAPD warns residents after spike in burglaries using Wi-Fi jammers that disable security cameras, smart doorbells 3 months ago:
Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.
- Comment on Google Promises Unlimited Cloud Storage; Then Cancels Plan; Then Tells Journalist His Life’s Work Will Be Deleted Without Enough Time To Transfer The Data 11 months ago:
I heard there was a process for requesting additional data, but you have to actually pay for the 5 users and they’ll bump it a few TB every couple months on request. That’s from people reporting their experience with support, so it might not be totally consistent.
I kind of get it though, people hear “unlimited storage” and then don’t even make an effort to be efficient with that space, and just want to keep everything forever. There’s a real cost to that storage, and it’s higher than many think since it’s not just a single HDD like many would have sitting on their desk but a series of arrays/pools and all the related systems to ensure reliability and uptime. They probably did some calculation where 99% of users would be profitable even with their “unlimited storage” and eating it on the other 1% was a reasonable advertising cost. Over time that calculation changed and they had to update the service.

Presumably it was GSuite/Google Workspace. While they advertised unlimited storage if you paid for 5 accounts, it wasn’t really enforced so you could pay something like $20/month and get unlimited storage on G-drive. There was a daily cap on how much data can be moved, but that’s fine for hosting incremental backups like many that took advantage.
- Comment on Risks of CPR 11 months ago:
I’ve had a few different First Aid courses and the instructors all have slightly different reasoning. One argument for compression only is potential for passing disease mouth to mouth, the newer courses tend to teach this because sometimes people that don’t feel comfortable doing rescue breaths will fail to do CPR at all. Another is that in cases where you’ve witnessed the event, the blood is already fairly well oxygenated and if medical help has a good response time the benefits of breaths are minimal. The first is more about compression only CPR being better than nothing, breaths are still advised where the rescuer feels comfortable doing so. The second is pretty situational.
- Comment on Heat-pump water heaters are a winner for the climate — and your wallet 11 months ago:
This is true in central Canada too. Heat pumps get pushed saying they put out 3 times as much heat as the energy they use, but electricity is 7x the cost of natural gas.
- Comment on Heat pumps can't take the cold? Nordics debunk the myth 1 year ago:
I’m sure there’s applications where that’s true, but then you’re essentially talking about having a gas furnace plus a heat pump, so you’re installation cost is close to the sum of both systems. Energy rates vary by region, but around here electricity is about 7 times the cost of gas, so a heat pump running at a coefficient of performance around 3 would still cost twice as much to run as a natural gas furnace, it would be cheaper to just turn off the heat pump altogether and only use that “supplementary” heat.
- Comment on Heat pumps can't take the cold? Nordics debunk the myth 1 year ago:
I suppose if electric heat is the primary option then sure. Around here though natural gas is pretty much ubiquitous and the cost per joule is a heck of a lot lower than electricity. About $6/GJ for natural gas, compared to about $42/GJ for electricity. Would need a pretty efficient heat pump to see the cost savings in my area.
- Comment on New to NAS - What are the recommended solutions? 1 year ago:
Something kind of unique about UnRaid is the JBOD plus parity array. With this you can keep most disks spun down while only the actively read/written disks need to be spun up. Combine with an SSD cache for your dockers/databases/recent data and UnRaid will put a lot less hours(heat, vibration) on your disks than any raid equivalent system that requires the whole array to be spun up for any disk activity. Performance won’t be as high as comparably sized RAID type arrays, but as bulk network storage for backups, media libraries, etc. it’s still plenty fast enough.
- Comment on Having separate dongles for network, audio, video etc. is even worse than just having specific cables for each 1 year ago:
Some of both. I remember a time where it felt like every time I got a new computer it had some different ports because they kept evolving. Modem/Ethernet, firewire 400/800, keyboard/mouse/USB, VGA/DVI/Displsyport(and mini versions of some). Sure, my old computer might have had a lot of different ports, but I might never have used some of them. For something like a laptop, I think 2x USB-C on each side is good for most, plus add hubbing to larger peripherals like HDD enclosures and displays and docks wouldn’t have to be so popular.
I feel like we’re just in the middle of a good transition period. Few years from now almost everything that can will be USB-C, we’re really just waiting out the replacement of all the existing devices and their incompatible ports.

The way I see it, the bigger the whole Lemmy community is, the more people can make smaller communities around niche topics. Steady, continuous growth is a good thing. What can be troublesome is rapid/inconsistent growth.
- Comment on [deleted] 1 year ago:
True, but a slow, steady growth is going to result in a better platform than having a flood of old redditors that take over. And that’s coming from a Reddit refugee, which I’d guess is a pretty significant portion of the user base these days. I saw a thread about Beehive considering leaving the fediverse altogether because they can’t keep up with all the fedderated content coming in that doesn’t meet their standards. I also think there needs to be further development of the software, things like users being able to block while instances(I’m fine with porn instances existing, but I don’t want them showing in my main feed and I don’t necessarily want to block everything labeled NSFW), as well as something comparable to the multi-Reddit system that lets me make groups of communities to browse together rather than just subscribed/home/all. The second would go a long way to getting that niche content communities up and running. The few niche communities that I have found seem to get buried under the more popular ones(which was an issue on Reddit for a long time too), so some method to bring that niche content to the surface on par with the bigger communities would go a long way too.
- Comment on Apple’s Decision to Kill Its CSAM Photo-Scanning Tool Sparks Fresh Controversy 1 year ago:
True, it’s hash-like in that the comparison is using some mathematic representation of the source material. It was intended to be a little fuzzy so it would still catch minor alterations like cropping, watermarks, rendering to a new format, etc…
The example I heard of was someone that was using an app for a remote doctors appointment. The doctor requested photos of the issue, a rash in the genital area of a minor, supposedly one included an adult hand touching the area involved. That photo ended up in Google’s cloud service where it was flagged, reported to law enforcement, and that users while Google account was frozen. The investigation quickly confirmed the innocence of the photo, and provided official documentation of such, but last I heard Google would not release the account.
- Comment on Apple’s Decision to Kill Its CSAM Photo-Scanning Tool Sparks Fresh Controversy 1 year ago:
Not really. The plan that Apple backpedaled on was to compare hashes photos on device to hashes of known CSAM material. They wouldn’t see any user-generated photos unless they was a hash collision. Other companies have been known to report false positives on user-generated photos and delete accounts with no process to recover them.
