When evaluating good vs harm for drugs or other treatments the risk for lethal side effects must be very small for the treatment to be approved. In this case it is also difficult to get reliable data on how much good and harm is done.
The amount of resources that goes into soccer in many countries is really astonishing. It can be seen as a modern equivalent to bread and circuses however.
I think home EV charging equipment is heading in the same direction as well. Very few have local and open APIs and instead depend on the vendors cloud service for control.
I don't know where you live, but in Europe there is a standardized backoffice management protocol that you can link up to basically anything in modern chargers. Except the cheapest of the cheapest.
I have mine running through EVCC.io, setting it up was as simple as throwing that thing in a docker container and figuring out the IP address of the chargepoint.
Yeah, but EV chargers are not that complicated. They are just smart contactors, with maaaybe some load management (EVSE can command the vehicle to reduce the charging rate).
Worst case, you just buy another one. It'll set you back a couple hundred dollars. Unpleasant, but not a big deal.
Air conditioning systems can easily cost more than $10k.
I am confused - aren't these boxes basically fancy three phase outlets? They probably have some safety fuses and some comms equipment, but the 'core' of the system is basically copper wire that connects you to the grid.
> aren't these boxes basically fancy three phase outlets?
That entirely depends LOL
So for AC chargers you are correct - 1 or 3 phases that go through a relay and, where required by code such as in Germany, a DC-sensitive RCBO, plus a small control board negotiating with the vehicle and monitoring voltage/current on one side and, again depending on where required by code, negotiating with the grid operator.
DC chargers are one hell of another beast, these have to contain all of the above plus powerful rectifiers, smoothing capacitors, EMI compliance...
Here in the UK at least they're generally single phase and required to moderate the power delivered to the vehicle based on the current electrical load in the house because most properties have quite low main cut-out fuse ratings. Bonus complications if you have solar or want any kind of access control.
It is astonishing indeed. In the long run I hope software catches up with the majority of other industries which has already realized that minimizing waste is a good idea. It might take a while but unless we get room temperature super conductivity or some other revolutionary tech first we will start thinking about efficiency again sooner or later.
You need a coordinator talking to the zigbee bulbs, in most cases this is a usb-dongle for $20-50. Zigbee2mqtt has a great list of different dongles and their pros/cons. The other functionality of a propriatary hub will be fulfilled by home assistant or Zigbee2mqtt+nodered.
SSO can seem intimidating to someone new to authentication implementations. I think this is in part because it is a bit complicated but also because it is an inherently invisible technology which we dont need think about as users. Sign in with fb/google on the other hand is something we all see in our day to day business and have at least some kind of mental picture of how it works. We've also seen it used as authentication for otherwise poorly implemented services so we might think that "since they managed to use it, how hard can it be?". Hence, a lot of developers and product owners choose those instead of SSO.
This sounds promising as a lot of use cases are shoe horned into the current verbs.
A bit surprised EVALUATE isn't discussed as a name since it would make sense both for search queries and other "get using body" scenarios.
It has a trackpoint with 2 buttons which tells us they did not put any serious effort into this input device. Would you use a 2 button mouse without scroll-wheel or a touchpad without 2-fingers scrolling?
I suspect this low effort goes for the whole product which is a budget laptop with marketing directed at decision makers instead of users.
Good catch. The Trackpoint in the photo had piqued my interest. But Trackpoint has come with 3 buttons for about 20 years, and I'm pretty sure the middle button gets used heavily by many people.
HP's been making two-button "trackpoints" forever. I don't get it either, but it's tradition at this point, not some sign of laziness.
And the laptop is decidedly not a budget laptop rebadge. It looks more like a tweaked EliteBook, their high-end business line. That doesn't automatically make it good, but I think your comment was unfair.
Actually, since they highlight “auto-tiling” window manager (I’m trying to see which one), I think the assumption is that users won’t be relying on the mouse all that much. Kind of the whole benefit of tiling window managers.
People who are excited about the trackpoint probably aren't interested in switching to another input method for scrolling. Personally I usually disable the touchpad ASAP on any new laptop I get.
You can scroll by holding down the middle trackpad button with your thumb and pushing the trackpoint in one direction or the other. You can even scroll horizontally this way. This is the main reason for the complaint about the missing middle button.
Why would anybody use a laptop keyboard and no mouse for serious development work? It's always an ergonomic nightmare.
Of course when travelling light you might choose to leave extra stuff at home. But how many of us need to travel light to a new location before starting their daily work?
The middle button (or "mouse button 2") is a legit pointer interface function that many apps use. Besides scrolling, it pastes, opens links in new tabs, and many application specific uses in eg Blender.
(But there's always been a middle button challenged user population subset around so apps have alternative ways of doing these, a bit like terminal apps can be used without a working meta)
The 2:1 setup was used to save lives after a mass shootings in Las Vegas a few years ago. They paired patiets of similar size, put them on the same ventilator and double the flow rate.
It was mentioned in a blog post by an ER physician linked from hn back then.
