struct··on What Is the Secure Enclave?
Educated guess: it may be the application processor also has a trusted execution environment containing stubs that communicate with the Secure Enclave. This would prevent kernel level exploits from writing to the shared memory and mailboxes.
struct··on Meizu Pro 5 Ubuntu Edition launches globally
At the bottom of the article: "Update on Ubuntu Phone security issue". Excellent advertising!
struct··on Show HN: Find the best recipe for any two foods, based on over 600k recipes
Super neat! I love this concept and I will totally use it. I particularly like its speed.
struct··on The Independent: first victim of a confounding digital future
Out of curiosity I just went to the Indy's website (now its only hope of survival). Unfortunately, my first thought was "damn, what the hell did I just click on?" If I want Kanye West, speculation on who'll be the next James Bond, and Duncan Bannatyne doing... something, that's what the Daily Mail's for. I really can't see how it has a chance.
struct··on Netflix Shuts Down Final Bits of Own Data Center Infrastructure
They do have Azure Service Fabric however, which does seem incredibly promising.
struct··on 60+ recordings of Satie's Gymnopedie One played simultaneously
Reminds me of Vangelis' Blade Runner soundtrack. Fascinating audio texture.
struct··on IBM's Watson Chief on Future of AI
I was interested in doing IBM's Watson Hackathon this month: I prototyped a little app that used their speech recognition service but quickly discovered that it couldn't understand even the most basic things that I said, whilst Nuance/Siri had no issues. I've also seen demos given by the Watson team consisting mostly of very deep Java stack traces, and "sorry, this question could not be answered, try later". Whilst I think that Watson seems more of a triumph of marketing over technical capability, they're at least headed in the right direction.
struct··on Show HN: A geeky way to surf news
You've got a bit of a typo on one of your screenshots ("latter" -> "later"). Otherwise: looks very nice :D
struct··on Google Brain Residency Program
Minimum qualifications: eligible to work in the United States. Damn.
struct··on Fukushima
One thing that grabs my attention is that the radiation levels in the contaminated zones are much lower than I thought they'd be. For context, the limit for a radiation worker in the US is 50 mSv. Obviously, I guess it depends on the radioactive isotopes released and what kind of radiation they release, but I'm still impressed.
struct··on PeachPy: Assembly Code Generation in High-Level Python
I remember coming across ARM's VIXL (https://github.com/armvixl/vixl), which is a similar concept but for C++, and just being blown away by how easy it was to twiddle the stack and assemble new functions on the fly - yee haw!
struct··on Warming up to Go
I've found that there are only two reasons I like Go: 1) It's concurrency model was a revelation compared to anything I did in the C world. 2) It's opinionated.

Everything else is a bonus. In Go, there's only one way to format your program correctly, there's only one way to document your program correctly, there's only one recommended way to serialize to JSON, it only has one (IMO really awesome package management system) etc. It's remarkable how little thought I now need to put into those things.

struct··on Adobe CEO desperately tries to avoid answering a simple question (2013)
It's about why traditionally distributed Adobe software is so expensive in Australia, and the CEO's response is that you shouldn't buy the old, traditionally distributed stuff, you should instead buy the stuff distributed via Creative Cloud.
struct··on Disasters That Worry Emergency Planners Most
Sounds obvious, but was that billion-dollar disaster graph adjusted for inflation?
struct··on New Horizons: Nasa spacecraft speeds past Pluto
I remember reading about Pluto in dozens of space books when I was a child, all filled with beautiful images sent from Voyager I and II, I'm so excited that we can finally add Pluto to that roster

Also, it's so incredible that the New Horizon's team has managed to get to something so small and far away!

struct··on RISC vs. CISC: What's the Difference?
I don't have access to the actual paper, but looking at the linked results[0]:

  Core Name 	Performance (MIPS) 	Energy (J) 	Power (W)
  Cortex A8 	178 	                25 	        0.8
  Cortex A9 	625 	                11 	        1.5
  Atom N450 	978 	                16 	        2.5
  i7-2700 	6089 	                28 	        25.5
So A9 delivers 625/1.5 = 417 MIPS per Watt, whereas the i7 delivers 6089/25.5 = 239 MIPS per Watt and the Atom delivers 391 MIPS per Watt.

In addition, their spreadsheet has an "energy" tab calculated from a "normalized" power figure (where Atom comes out on top), but if you multiply the measured figures without the dubious adjustment, it seems that the A9 is actually more efficient (at least when you consider the board power), and MIPS is conspicuously absent from this spreadsheet. So the fundamental conclusion is "either ARM or Intel are better, but it depends on what you measure under what workload".

struct··on Docker really is the future
The only potential use I see for Docker's potential is to distribute applications with data as combined appliances: so if you want a PostGIS server preloaded with maps, you can do `docker fetch some_postgis_server` and end up with something you can query. But then when you try to build such an appliance (containing a lot of data), and push it to Docker Hub, it ends up failing with a mysterious error code overnight, and you open a ticket, and nobody follows up on that ticket. Docker has to get better at that kind of thing before I can consider using it again.
struct··on Passwordless login done right
Cool idea, how is re-authentication handled beyond the initial sign up? Do you get a text message each time?
struct··on Apple might be running a web crawler written in Go
Perhaps a proxy designed for iOS testing?
struct··on Ask HN: What (side) projects are you working on?
I've long thought about doing this with arXiv to determine if you could extract results and synthesize answers to questions. Is anything like that part of the goals for The ContentMine?
struct··on Ask HN: What (side) projects are you working on?
I work on GoLearn as a side project. It's a general-purpose machine learning library written in Go.

https://github.com/sjwhitworth/golearn

I started it because I wanted to revise some data mining algorithms, I've since moved on to an unrelated career, but I'm still truly addicted to contributing...

struct··on SAP agrees to buy expense software maker Concur for $7.3B
I can see the email from HR right now: "To access Concur, go to the SAP Portal"

Nnnnooooooo!

struct··on Fighting spam with BotMaker
"Key reduction in a spam metric". Stupid question: if they know what spam is well enough to chart it, then why not just use that to fight it?
struct··on Show HN: GoLearn
(Disclaimer: I'm one of the authors).

For decision trees, the only thing that's available at the moment is a half-baked ID3 algorithm, but I've been looking at CloudForest and it's a very impressive piece of work.

Performance isn't very good yet: this is due to some data representation decisions, but it now supports grouping attributes which will allow us to optimise to acceptable performance levels (I have a prototype KNN version which achieved similar performance levels to this guy's Rust[1] implementation).

struct··on LyX 2.1.0 released
LyX is not the sexiest app out there, but it's an indispensable tool for me: rock solid, feature-filled, and easy to use - a great example of open source done right.
struct··on A Bitcoin Address with 782,000 BTC Moved Through It
Seems that quite a lot of the volume on that address[1] is about 40% of the volume of the of the stuff going through MT Gox[2]. Might be a coincidence.

struct··on Google Security Reward Programs Update
$10 000 still seems a bit low for a truly serious vulnerability. Could Google start a vulnerability bidding war and simply make it too expensive to acquire them?
struct··on MobileWorks, finding workers via the cloud [video]
So, Mechanical Turk?

struct··on Data looks better naked
Good analysis here: http://betterposters.blogspot.co.uk/2013/09/link-roundup-for...

If you don't have the y-axis, then a) there's no point in having it as a graph and b) there's the possibility for manipulative display.
