Without a fan, it's hard to understand how high performance could be sustainable for long term number crunching. Maybe it's not for sustained calculation? Still even if it's just a burst it means the thing won't be laggy. It just won't replace the laptops use case in serious calculations
Remember when the PPC supposedly outperformed x86? They never said it was only on integer math.
They ran on-stage demos of doing complete photoshop editing workflows and there are minutes of difference between the Intel and PPC outcomes. Those were real world examples of the PPC creaming the intel at that time. Of course eventually intel won back the crown as the ppc development went off-track.
The same sort of thing goes on with the AMD ryzen vs intel right now too.
Well this is really surprising. I wonder what spec they gave up to get that. My understanding,perhaps wrong, is the A12 is an ARM, probably some derivative of an ARM cortex 64 bit. Is it true that Arm I liscences the basic instruction system but people are free to tweak the silicon? if not you'd think other makers using the ARM design would be reporting the same specs already. if so it's possible I guess that apple found a way to make the ARM processor as fast as a flagship Intel processor.
But ARM has always been known for being low power. So did they give up some low power spec?
Perhaps the benchmarks used are register or in-cache calculation not memory fetches?
Anyhow if we can credit these benchmarks as being indicative of number crunching performance this is rearranges my world view of ARM versus Intel. Need to start paying attention and not assuming that ARM processors are slow.
I suspect this also puts a wrench into microsofts gears. Have microsofts ARM based tablet based OS caught up with their x86 based OS yet? 5 years ago the RT models were crippled.
Here's an interesting popular press article from this year talking about the slow turn on this theory. Sure people have had that on the list of possibilities but no proof. Now the pendulum is swinging that direction, but only recently.
It really is turning THIS YEAR, because it's only in the last year that the most advanced and well studied Anti-alzheimer's drugs targeting plaque forming pathways failed. Thus old speculations are being reconsidered and there's a body of proof to support them.
So adter decades and decades of work people figured out Ulcers were bacterial not a defect in proteins coating the stomach walls.. Very recently it came to light that Alzheimers may be a viral or bacterial infection and the amyloid plaques actually are a defense mechanism. WHich explains why all the anti-amaloid drugs failed.
Amaloids come from a kind of protein misfolding.
Now they are attributing parkinsons to misfolded protein.
This study is interesting because we now suspect the appendix's purpose is to be a place where gut bacteria can go dormant and wait to re-seed the gut to maintain diversity. In the age of antibiotics and the rise of c. Difficile the appendix reseed may have become more important. THose infections are now treated with fecal transplants.
So appexicies harbor "good" bacteria. Perhaps the misfolded proteins their are their to keep them alive and dormant or to knock down the infection by bad bacteria (appendicitis). Perhaps it is the bacteria migrating to the brain that is brining along the misfolded proteins.
Just saying this sounds like "here we go again" when it comes to blaming the proteins for a bacterial problem. But maybe they are right. THe thing is, and the clue to the other two cases,was asking why didn't those bad proteins get evolved away. The appendix is not only in other species but it has been independently evolved in multiple species. It's there for some damn good reason and so are the proteins screted there.
I love jupyternotebooks. But it's matlab. Well a broken inferior matlab. I do like python syntax better than matlab but that's just a sugar.
The upcoming Jupiterlab is a slavishly copy of the matlab ide.
It reminds me of how Linux desktop managers were always copying the last generation of windows.
I'm not complaining! I use mint and it owes a lot to windows too.
Mint however is actually superior to windows now.
But look at something like staroffice libre office. Ow... the pain. It's like a bad ms office 5, except you can only use it if you have thumbtacks in your shoes. They copied everything that was bad just so it was the same.
Jupiter is really nice and I use it in preference to matlab because it's so portable and I can use other python packages. But unless you used matlab you may not realize it's just a fast follower of ideas already tested out by matlab
I'd bet this might be more efficient to extract or compress too. Since the whole operation would be running at a constant pressure you could optimize the turbines or whatever is used for a specific pressure rather than have ones that have to operate across the range 300bar to 70 bar with the same efficiency. The pressure is low enough and the volume small enough that above ground storage in tanks instead of deep caverns is possible. So presumably lower losses. You could even pipe the liquid to where you wanted to expand it.
Would Carbon Dioxide make more sense? It turns to liquid around 800PSI, so the stored volume is greater and it doesn't require increasing the pressure to store more energy (just increase the volume). Finally, when you extract it you can make La Croix sparking soda's for an entire town's water supply at no cost.
Basically there's two things here 1. Telcos got credits and contracts in return for promise to supply net neutral services to rural areas 2. Amit Pai thinks that since we no longer have net neutrality, the Telco's could monetize the rural areas better with exclusive contents services.
who needs to securely exchange a key? Just use a public key encryption to transmit the message (the message could be a key for a non-public key encryption)
Unless your time and certainty has no value, apple laptops are the lowest total ownership costs as far as I can tell. Even IBM agrees with that. So much time is spent screwing around with the dissappointment and incompatibilieis or learning experiences it takes with changing models year to year with other brands there's no point in spending that money whey you could just get an apple, know how much it's going to cost you right up front in time and effort and certainty it will work. The macs tend to last longer too.
Sure when I'm hunging for cheap like in servers or for secondary computers or ones for specific missions I always buy Linux machines. No argument there that they are way cheaper to buy. And as long as I know they will work for what I plan in a specific situation there's no reason to buy apple.
And if all you want is a machine to check your twitter account and do google docs then the machine with the absolute lowest chance of letting you down is a chromebook.
But if you want one computer that can do everything, take on new missions, and act just like your old one did with perfect continuity of operations, then an apple is it unless hourly rate of pay isn't very high. Ever waste a day screwing with a computer? your salary+benefits+lossed_sales == what it cost you that day.
A nice 8193 bit key should be as much protection as anyone ever needs.
While Bill Gates never said that it may be true for as long as necessary. Just use some extra long key to encode the exchange of shorter length keys. Why do we need quantum key exchange?
I see nothing hypocritical here. In one case they are forced to follow local chinese laws that the US finds repugnant. The other is selling private data which isn't covered by US laws mostly.
In actual fact in the US we also allow authorities to demand access to data. Apple is actually making technology that prevents that from being abused. Whereas other's are selling the data they harvest either directly or through what they allow the apps to collect.
How many times do people have to explain that slowing it sown when the battery is weak is a good idea, should be the default, and it should perhaps allow an override. But an override is not expected initially in the software because over draining a Li battery is dangerous. So maybe you llow som over ride but only after you have studied the issue more.
Apple and I assume samsung were acting in good faith here.
Way more secure in practice. Especially if you are paying a company that makes it's money on selling security not advertising or monetizing my phone data
I actually like having the phone OS tightly managed by the OS provider (not the phone maker). I like this lock down. I will gladly pay extra for it because for me the phone is my one immutable security tool where dependability out weighs the importance of customization. I have a desktop computer for customizaton
But that's just me. I realize other's don't feel that way. Which is a good reason for their to be a competitive market with different approaches. I personally go with apple because if you look at history you know you are buying dependability and freedom from most hassles that arise from lack of full control. Sure apple makes their mistakes but let's not kid each other about which company is the one with the history of being pretty darn safe.
Google at first went one way. More open than apple. Now they are slowly closing everything up. In someplaces like chromeOS they may have managed to actually lock it up so tight that it's the safest machine going--- but it's way way too far locked down-- those things blow for general purpose uses even though they are fantastic for the envelope of things they do do. (there's hop for the future with the VMs they are allowing!).
But on android it's always been a sort of wild west of variable things. Now they are trying to close it up.
Unfortunately in my opinion, the way they are closing android up shows they are more interested in the monopoly aspects of closure than the safety aspects of closure. In this respect it's almost of mirror of the things we really loath about microsofts early strategies. In this google is being more evil than good.
I use bussiness management products from oracle with an underlying oracle database. I feel like sometimes the IT department must not be shoveling enough coal into the boiler or something beacuse this antiquated inflexible interface just stalls all the time and very frequently has to go down for some sort of synchronization. It's slick like Amazon's web site. I don't understand why Oracle even exists given my experience with it.

Yes but it does care about bacterial infections hence the defense mechanisms that might have long term negative attributes.

Oddly this finally an on topic comment

minus the lead. minus the low energy density.
The beauty of this is that you can also use the Heat as well as the Work.
when compressing it will get hot, so use this for heating hot water. And when you release it things get cold. So chill your beer.
Basically there's two things here
1. Telcos got credits and contracts in return for promise to supply net neutral services to rural areas
2. Amit Pai thinks that since we no longer have net neutrality, the Telco's could monetize the rural areas better with exclusive contents services.
