iOS Safari can play videos non-fullscreen with the playsinline or webkit-playsinline attributes. The fun thing though is that this attribute must be enabled manually on each web view, so if some other app is embedding your page and they didn't enable it, your videos will play fullscreen despite the attribute being set.
> That‘s not true. Going in a straight line, blocking wheels will stop you in less distance than with active ABS.
Most certainly not. The sliding coefficient of friction of a tire is quite a bit less than the static coefficient of friction. Shortest stopping distance is achieved by keeping the tire rolling, just on the very edge of lockup, for the entire braking distance.
Early ABS systems had slow pulse cycles and couldn't control wheels individually, so a good driver could outbrake them but the ones from the last 20 years are quite good.
ABS is one rare example of a safety technology that doesn't have much drawbacks. Very much unlike newer technologies like lane assist and self braking, which have benefits but also clear drawbacks.
Even for ABS though, there are edge case dangers that a non-ABS car wouldn't have (like ice mode disabling brakes when not on ice).
There's no magic answer with tehcnologies. Every time a system increases complexity, it increases failure mode potential as well.
I think the friction of wheels is lower when the wheels lock up vs when they go with the speed of the road.
From Wikipedia[1]:
> Kinetic friction, also known as dynamic friction or sliding friction, occurs when two objects are moving relative to each other and rub together (like a sled on the ground). The coefficient of kinetic friction is typically denoted as μk, and is usually less than the coefficient of static friction for the same materials.[40][41]
I feel like I have a fairly solid backup system for all of my important files. They are protected against elementary disasters and cyber attacks alike.
However the only thing I struggle with are my phone photos. I recently caved in and started using iCloud Photos due to the convenience of having all my phone photos alwas available, searchable and tagged, even if the library size exceeds my phone‘s capacity.
Does anyone know a reliable and automatable way to back up this iCloud photo library on a self hosted server?
I'm also interested in this. I have iCloud for Windows installed on a VM with lots of attached storage, but it doesn't seem to persistently/reliably download photos unattended.
I suppose another way to do it would be with a Mac and then periodically backing up the local Photo Library, but that still leaves the photos tied up in Apple's proprietary library format. Plus you need a spare Mac just laying around and always on.
I spent extensive time evaluating this problem, and tried a whole bunch of different things:
Nextcloud, Resilio, iCloud, etc etc etc.
Honestly? Just using Google Photos is probably the best bet for most folks, whether you’re on iOS or something else. I personally picked OneDrive for my use case since it is both more performant for large data sync and 6 TB + Office 365 for a family plan beat out the alternatives on pricing.
Eh... I'd definitely do a Google Takeout to verify everything's OK before you delete your originals.
You may think the downsampled image is sufficient for lossy backups, but older images stored in "high quality" in my personal GP library were almost wholly stripped of metadata, including when the photo was taken.
(Many of my users have suffered from this as well, which is why I built tag value inference into PhotoStructure to try to help spackle over these metadata holes).
That’s good advice for those that care, and I should have mentioned it, especially for HN crowd. I definitely noticed this problem when I did Google Takeout on my photos dating back to the Picasa days.
I still think that for most people (and on HN, where we care more about fighting data entropy, there might be significantly lower overlap with the majority), Google Photos is the best option.
I do this with Syncthing (not just photos, but all phone files), a very customizeable file sync tool, it can do trash bin and versioning similar to cloud storage providers. As I heard sadly it doesn't work so well in iOS due to its restrictions though.
They at least offer local network syncing, instead of requiring a cloud account (which is a deal breaker for me). This lets you keep your passwords in sync between your Computer (master) and mobile devices without them ever leaving your home.
All that does of course still require trust in the company, but at least not in their cloud infrastructure and, well, the internet...
It's definitely not all the new controllers, although with the UDM line you might be right. I think there's a huge intersection between people who would buy those specific devices and people who are perfectly happy to have remote access to their control plane in the cloud.
It is also about dark patterns. I never had the cloud option enabled. One night after a long day I upgraded the controller software. I noticed a message like “do you want to login?” and wasn’t awake enough to realise that it asked for my ui.com account and that after that cloud management was enabled and my phone switched to authenticate from a direct connection with the local credentials to using the ui.com credentials.
It looks like what I was referring to is that they recently made the initial controller setup on the cloudkey require a cloud account [1], but you can migrate to local only after the initial setup.
So the only remaining 'local only' from start to finish is for self-hosted I guess.
I have a cloud key gen2 plus and do not have a UI.com account. I would classify getting the network controller setup without having one initially "mildly annoying but worth it".
I'm also floored at the number of people who are spinning the existence of a self-hosted controller as somehow a bad thing...?
The UDM and UDM-Pro force you to set up a UI.com account, and cannot be used with external Unifi controllers like one you might run on a server, PC or cloud key (Ubiquiti's management software on a Power over Ethernet powered dongle, does not require a UI.com account).
They do - first thing I did though was then go in and add a local account, and disable remote access (I have a wireguard tunnel that terminates on a server behind my firewall if I need remote access).
Coming from Sketchup and being a Software Engineer, parametric design in FreeCAD is a game changer for me.
For example being able to define a cabinet side length as the outdoor dimension minus twice the side panel thickness allows you to decide wood thicknesses after finishing the design without redoing everything.
However, FreeCAD seems to be highly unstable on macOS and Retina screens are not supported very well.
You’re correct that parametric is cool & FreeCAD adds that flexibility.
One note about Sketchup is it encourages choosing standard sized items from the parts library. Choosing from the library (for example, choosing a standard 2x4 board or a standard door) means you’ll find real-world equivalents at Home Depot & avoid a lot of cost.
