Yes, this is laugh-worthy. It's Apple's sneaky manner of building planned obsolescence into otherwise very competent devices. Just like my 4S, the brand spanking 6S+ will in a few years be choked by iOS updates's climbing RAM requirements. Not updating isn't an option either, as app updates demand the latest OS quickly afterward.
The iPad Pro is much more affected by this because it competes with Wintel devices. When you compare it to the Surface Pro, the later isn't considerably beefier except when it comes to RAM, which is enough on its own to give it double the life span...
That's definitely the best problem ever solved by GP, though given the unfathomably enormous computational resources poured into it, it's still hard to say it was any better than a brute force approach! ;)
It's almost definitely better than brute force. The number of possible sequences of dna of size n base pairs is exponential in n.
The earth has only existed ~1e9 years. Assuming some finite average number of "computational ops per year", the number of possible dna strands quickly exceeds the total computational capacity of the planet since its birth.
Evolution is not trying to find one particular DNA string out of that exponentially sized set. There are lots of members of that set that are viable organisms.
In any case this is beside the point. The fact remains that genetic programming is a class of algorithms that has not been succesful in the slightest. People should just stop talking about it as if it was anything other than a complete failure, since that will only lead to even more wasted human effort. Gradient descent on the other hand is hugely succesful in solving a wide variety of real problems.
Im not advocating GP > nn+grad. I'm just saying nobody knows why nn+grad performs better on practical problems. Also nn+grad methods were essentially complete failures for the first 3-4 decades of their existence (invented in 60s, legit results like Lecun or Hinton in like 90s/00s).
This is so wrong at so many levels (sadly quite characteristic of the GA crowd) that I can only suggest reading up on the background and the math of it. Good keywords would be stochastic gradient descent, spin glasses and renormalization groups.
Whether nns have an interpretation as spin systems is completely nonresponsive to the hardness of training them. Ie minimizing "free energy" in spin systems is as NP-hard as minimizing training error in nns.
I have to agree-MD isn't "off" by a whole lot but just enough to hinder the user experience. In particular, headers and topbars are oversized beyond what's reasonable, margins are excessive in content elements, and ironically this combination makes interfaces feel very boxed-in AND with poor data density on top of that...
Totally agree with you here. Brunch is fantastic for its minimal config requirements and super-fast performance. Oddly enough, in the JS world I've found it best to ignore all the hype around the latest and newest framework, and just go with something that has a small and loyal following and stick with it.
I mean, look at all the people who moved to working with Angular because it was "made by Google, so you could trust it to stick around". Now those people are using React, and soon they'll move to Angular 2. I've found that hyped technologies almost never have a fraction of the robustness and staying power that they claim to...
At the time I'd been as long with AngularJS as I have been with React now, I despised AngularJS and wanted to violently murder past-me who decided to use it.
With React I'm still as confident in my choice as I was a week into using it. In fact, the more I get to know it, the more confident I grow. With AngularJS, it was quite the opposite.
If anything I'd say that AngularJS being promoted by Google only made me more cautious about technologies promoted by Google. Google doesn't actually dogfood AngularJS. I know, they have some tool somewhere that uses it and apparently there are people using that tool, but it's not nearly as customer-facing as the code in which Facebook and Instagram use React.
But I didn't chose React because of the hype. In fact, AngularJS was still being hyped when I decided to try React. I tried React because someone recommend it to me and told me to give it five minutes of suspended judgement. If I had gone by my first impression, JSX and Facebook both would have scared me off.
> battery life that would probably outlast 3-4 iPhones.
And functional life as well. iOS 8 crippled A5 devices which had previously chugging along quite decently. Planned obsolescence sucks (in iDevices' case, it also affects present performance, i.e. Safari constantly having to reload tabs because the device has little RAM to spare). Unlike a smartphone, a simpler device won't be reduced to be unable to perform its more basic functionality decently a few years down the road...
You don't have to upgrade to iOS 8. Similarly, the 8210 wouldn't have had software upgrades, which naturally would be geared towards newer devices and cause the device to also slow down.
Security confounds that strategy unless you're planning to stop using data once an exploit is discovered which won't be patched on the old OS, which in this case happened the day iOS 8 shipped.
That article doesn't actually counter what the OP says. In fact it ends by stating that SS is being more strained and giving diminishing returns as time passes by, which sounds disturbingly like a ponzi scheme. It's unsustainable by design even without free-riders, much less with min-maxers gaming the system to not put anything in.
I don't know why you think social security is necessarily unsustainable. It's been running a massive surplus since the 80s. Unfortunately it was borrowed from to finance wars in the middle east, but that's not a problem with social security.
As a point of comparison, you can get a Lumia 520 for less. It's a really decent smartphone too from a good brand. It will be interesting to see if Mozilla can yield the combination of quality/value to succeed.
It's what I've observed as well. Plenty of low-income people get cheap chinese tablets, usually generic-brand entry-level models. No idea about the price but I don't think they're a hair above $100, possibly less than half that.
What Windows 8 did wrong was messing with the familiar old-school interface a bit too much, which made many non-tech-savvy users confused and miserable. My dad had a terrible time with Windows 8. But me? The Surface pro is easily among my favorite devices ever.
The iPad Pro is much more affected by this because it competes with Wintel devices. When you compare it to the Surface Pro, the later isn't considerably beefier except when it comes to RAM, which is enough on its own to give it double the life span...
