If you are a professional and earn the accordant salary then your time has value. In that case the cost of the tools is irrelevant to how productive they make you. People who complain about apple's price tag are not using it professionally. And indeed, I personally buy apples for my job and linux for my home computer precisely because of the price issue. if I wast a single day at work due to my computer I paid for the apple. At home, that's not the case.
Yes indeedy --in theory-- but the optimizations are everything that makes tensorflow useful. Like SIMD or the pinning of memory for GPU transfers. So no, in reality. You might as well say that one could just compile Linux or Windows or Mac OSX for any cpu architecture just by flipping a command line arg.
Recently Linus ranted about how server class ARM development was a deadend because of the lack of sufficient "home" computers for normal use (he didn't literally mean home, but rather personal-computers). The answers that! On the otherhand for those of us who rely on libraries like say TensorFLow that doesn't look too good since a lot of that is X86.
It will be interesting to see if Developers will flock to this as the optimum ARM development platform or flee from apple due to lack of x86 in their primary laptop.
Anyone know how it gets the resolution it needs? Even ultrasonics have long wavelengths. It would have to be extremely high frequency to image the finger. But perhaps they use some sort of channeled time domain reflectometry or near field methods to get the lateral resolution. Still it's not obvious what they mean from the description

The big news here is that the tinfoil hat crowd was right after all. This is sort of amazing. While it was always plausible that sufficiently strong EM waves might disrupt conventional eired neural connections there wasn't a known mechanism by which weak EM waves would be harmful.
Now there is a very clearly plausible way weak EM waves might distrup parts of ones neural activity without disruption other parts making it very hard to actually measure the effect. THat is presumably these severed neuron coupling systems are varied from person to person so the effects would be diffuse and variable and subtle.
I can't think, the neighbors Wifi is melting my brain. Better put on my reynolds brand thinking cap.
Before they pass this they need to pass a data privacy liability act. It should state the penalty for every occurence of a data record being lost to hackers because of inadequte security on the data base. FOr example, $1 million for loss of a DNA record, $500K for loss of a financial record, $250K for loss of a social security number. $100K for loss of a purchase history record and so on. Additionally the penalty would apply not just to the person that collected the data in the first place but separately to any other parties it was entrusted to who lost it. So shared data would be subject to double the penalty. This would prevent avoiding responsibility by delegation.
If they did that then I'd not be quite as fearful of this. It could still be abused by the gov't itself but this would reasonably limit the scope
I've wondered for some time why Honeypots are not a near-universal solution to this. That is, each router can host a bunch of fake servers with real IP addresses on the network then watch for intrusion attempted or real on these fake nodes. You don' t need a lot of horsepower backing the fake nodes since they are not doing anything except mimicking a normal level of net traffic to other computers so it's not a burden on the system or the routers. And if one was worried the hackers could eventually learn to spot these virtual nodes in the routers (perhapsvia hacking the router itself), then one could also sprinkle in a few real computers on the network acting as honey pots.
In any event, any attempt to break in or a successful one on a honey pot, is 100% evidence the network is experiencing lateral intrusions and you just shut it down immediately.
There's case studies many economics classes use of how the airlines in the 1970s would evade the collusion in restraint of trade laws. Basically, they developed a process for proposing fare changes. They would announce a scheduled fare increase a month in advance. If the other company followed suit they would enact it if they didn't they would retract it or post a fare decrease shortly after that. It worked quite well till the regulators figured it out. Braniff (deceased high end airline) was the ringleader.
These pricing algorithms just accomplish this one time scales of hours rather than months.
but it's just old wine in new bottles. No one invented anything or changed anything. But the amplification and universality of it made the problem worse.
But what actually makes this interesting is that it may also be an emergent behavior as opposed to either intentional programming or an untended artifact of some algorithm. THat is, if an AI is simply asked to maximize profit in a multi-agent system it's entirely possible it will learn this tit for tat strategy. Humans do in cooperation-games in behavior theory.
The only reason to run Windows is to use the Office Suite for compatibility with the modern bussiness world and much of the academic world. Thems the standards regardless of preferences or your personally proven experience with working outside the MSOffice-industrial-complex.
So if the raspi doesn't run Office what's the point of running windows?
You now are running a machine intended for being either a task specific embedded machine or as a light weight computer. Running windows on it instead of linux or some RT os is more of a dare (like scottish cuisine) than a useful idea.
The comeback is, well then how come apple doesn' sell a 50 watt charger? Evidently there is some limit and I discussed what the sources of the limits are.
I would strongly speculate that the 12 watts charger only really runs at 12 watts under optimal cooling conditions or for part of the cylce. It's may possibly be more of a fast-charger as I noted at the end.
There may be a rationale for 5W versus 20W chargers that has to do with making the phone batteries degrade slower and reduce the risk of fire.
But I do know that my phone gets pretty warm when it is charging and though heat flux does not scale perfectly linearly with temperature, for small differences it's linear enough to say that if you double the charging rate you will double the temperature rise.
Since I'd not want a phone that was 3 times hotter than room temperature rise than it gets now I think this battery charge rate is fixed by this. The only way to do better would be to make the charging heat loss closer to the thermodynamic limit. it's possible different batteries can have different charging heat losses but I'd guess that every phone maker uses the most efficient one currently possible.
Some fixed fraction of every watt that fluxes into storage goes into heat. I'm not quite sure what that amount is, certainly the laws of thermodynamics put a lower bound on that but if it's like most things it's way more than that, probably in double digit percentages.
So that goes to heat. The battery has a fixed surface area to volume ratio. So the rate at which is can dissipate this heat to it's surroundings is fixed by that, which apple can control, and the surroundings which apple cannot control. e.g. is it in the foam padded (insulating) pocket of your back or jacket? Is it under a pillow or a sheaf of papers. Is it standing up in the air or flat in on a table?
If you plan for a reasonable first case, and then build in thermal protection for the rest, then one can figure out how much the temperature inside the battery can get up to for any given charge rate.
At some point the battery is harmed by this temperature. It might just degrade its lifetime but in some cases that degradation also increases the chance of fire or battery swelling.
In any case there is some maximum advisable charge rate for a given size battery. if this is the limit, then It would seem reasonable that an ipad with many times the surfaces area (and volume) could sustain a higher charge rate than an iphone.
I cant say that apple is bumping into this limit because it's too hard to guess without knowing what the battery limits are. But given how warm the phone gets now I'd say they can't charge much faster without making it a lot hotter.
Finally I'll note that this is slightly different than short term fast charging. Since the phone and batter also have a heat capacity, it's possible to temporarily charge the phone up to some total energy without appreciable temperature rise. SO you may be able to partially charge the battery quite fast. But at some point you would have to fall back to the thermodynamic limit described above.
reminds me of segregation and integration. You may recall the Southern states arguing that separate but equal access to facilities would work really well and provided equivalence to all races.
Net Neutrality with paid prioritization is (mostly) an oxymoron, and the same vein as separate but equal. Separate virtually gaurentees not equal. And paid priority isn't neutral.
I'm okay with content classes that have priorty over others. e.g. low latency channels for tele-medicine, medium latency for video, and high latency for text.
And i'm even okay with people having to pay more if they are in the low latency class designation. (which could be a dangerousloophole if abused, but a very reasonable concept if not abused).
but paid priority among equivalent content is by definition not content neutral

No you can override the signed app protections easily, especially if you are a developer.
