Once Apple ditched DiscoverD, my wifi and bluetooth woes disappeared instantly. I had a problem where my connection speed suddenly would drop to no more that about 7k as second through wifi which required zapping the PRAM on my 2013 MacBook Pro until a week or so the connection would start exhibiting the same problems. mDNSresponder seems to work like a charm in Yosemite.
> Have you seen how many direct-to-DVD/streaming 'movies' there are that cash in on their popular franchises?

I have a strong feeling that a lot of those are made exclusively for toddlers, who tend to frequently get obsessed with consuming anything-and-everything related to a given franchise. I don't feel bad that they're not well-made; nobody could keep pumping good pieces of media out at the rate an obsessive toddler will want to consume them.

How do you use your phone, that you get less than a single day's battery life from the current Nexus 6? I can easily get 1-2 days use out of mine.

Yes, but according to google they were tapping the "dark fiber" (private lines only carrying google traffic) that were not encrypted between their data centers.

Those lines were for things like data replication so it was a goldmine for the NSA to tap. Those transmissions have since been encrypted.
Well, if android phones still had the ability to masquerade as a USB drive (in order to move files/photos/whatever) on and off, then I could see leaving the SD card in place forever.

But android phones don't currently have the ability to behave as a simple USB drive when you plug them into the computer.

So if you're even a little bit discerning, and you refuse to install silly helper apps and photo-importers and android-buddy programs on your computers, you need some other (sane) way to move files on and off the phone - and that is the SD card.

They're just files. You don't need a little helper app or to open up iPhoto and "import" or any of this silliness. You just need a dumb block device that you can move back and forth.

intersect :: Segment -> Segment -> Maybe Segment

> What would a Nothing result mean? Would it mean that the 2 segments do not intersect, or would it mean that one of the segments was invalid?

The way I see it, it can only mean that they do not intersect, and never that one of the segments was invalid. This is because a Segment is guaranteed to be valid by construction; after all, that's precisely the property you bought by using mkSegment!

I was using it for a comparison to establish a medium size organization designed to advocate issues. It does do some YRO because that overlaps with some "small government" advocacy see http://www.freedomworks.org/content/sopa-and-pipa-would-dest... but mostly they have some effectiveness and are around where I thought the EFF might be size wise although that is debatable.

Would be great if there was a local version available, that can check private repos. You shouldn't commit AWS credentials, etc even to private repos (because parts of them might become public in the future, or some developers should not have access to the live AWS servers).
I suppose that's right. However, my point was that Syria has been the "lone wolf"; it did not give in to Western pressure, unlike a lot of other regimes in the region. As such, it was always a target for destabilization.

Correct, Intel is playing dirty with Skylake. Sandybridge (i7-3820), IvyBridge (i7-4820), and Haswell (i7-5930k) all had 40 PCIE lane high-end consumer CPUs. Such CPUs could be used with PLX PCIE switches to build inexpensive quad-GPU supercomputers:

http://exxactcorp.com/index.php/solution/solu_list/85

As far as I can tell, there is no Skylake analog to these CPUs. So instead of building something better than a GPU, all Intel can do is buy Altera and do their worst to raise the price of building a fat GPU server.

Previously, they blocked the ability to send P2P copies between GPUs over QPI. But PLX 8747 PCIE switches provided a nice workaround (as will a single 8796 switch this round).

I guess those can, do, and those who can't, erect roadblocks.
I'll counter that illustration. Let's assume that there is no oil left that doesn't have claim by an oil company and therefore you are unable to compete directly in the oil manufacturing business. But, what you are really saying is that you think that the price for what utilization oil brings is too high, and thus you can compete with oil with another resource. This means that you could invest in whale oil, coal, solar, wind, natural gas, or nuclear, or something else. If the price of oil is too high, then there is large amounts of incentive to invest in something that might not even exist.

By offering those resources to the same spaces that utilize oil, you are competing with oil. If you are able to take customers from oil, oil will be forced to reduce their prices.

As I mentioned in the previous comment, you should check out the keywords I mentioned. And if you are thinking that I'm missing something, please direct some resources my way.
How to Create Company Values That Mean Something
Unreadible sales pitch. Yuck.
"The A53 cores will likely carry the vast majority of every day use, and redouble the battery savings."

non-ARM-manufacturer citation needed :).
My experience as a compiler guy (that makes the toolchains for these kinds of phones) has been that big little brings improvements to what these guys can shove on a chip and advertise, but so far not real improvements to battery life or real numbers.

There reason why is pretty simple.

In an ideal world, you don't want anything running at all.
You don't want A53's "handling the majority of the workload".
What you want is to wake up, do whatever work is needed as fast as possible, and go back to sleep. Period. Sleeping chips are lower power, by far, than idling chips.

If it's faster to do that work with an A57, it'll generally give you better battery life to do that.
Again, this is right now, based on perf per watt/blah blah blah.
Maybe someday, in the future, a53's will be so low power vs a57 that doing something else makes sense.
But it's not true now, AFAIK.

Instead, they make big-little because they can't really increase the speed of the higher end cores more without increasing power usage too much.
Sort of readable, imo. I mean, a few simple function calls are nicely readable, but blocking calls quickly turn into an unreadable mess in my experience.
> Haskell and OCaml are both great languages, but to a lot of people, they come off as much more "academic" or "ivory tower," and require a lot more effort to learn to use effectively for people who are not used to functional programming.

I think the problem is that people who are used to C++ and Python approach Haskell as if it were just another language, in that category of languages.

You need you learn some new stuff in order to really understand Haskell, but that's hardly a fault. I actually think non-programmers would have an easier time learning Haskell than experienced programmers. There really isn't anything inherently difficult in Haskell. It just requires a different approach.

It can be annoying to write Haskell programs sometimes, because it's so hard to get it to just compile. But that's the entire point: the fact that the compiler can do so much when we restrict ourselves to pure functions. It also forces us to figure out exactly what our program needs to do, before we can implement it, rather than build on top of proof-of-concepts, as is typical with Python.

If the rest of their uniform were neutral, it might work out.

I think this title is a little misleading. The article says nothing about the FBI's ability to beat encryption, just that they have more success with keyloggers and backdoors than they're willing to admit. Encryption used correctly is still able to "stop the FBI".
Appreciate your efforts in this regard!
The blog was a good read. I agree with acconsta that the description doesn't seem to utilize Rust's better attributes. Plus, that it's "starting to look like Linux" (author) may or may not be good. I'd look at Wirth's Oberon or A2 Bluebottle for a simpler start: type-safe, memory-safe (mostly), GC'd OS with good documentation, source available, and a simplicity focus for easy re-implementation. Rust, in theory, can do whatever it did and faster.

Additionally, if doing clean-slate, might be worth looking into alternative models for constructing or securing OS's. EROS security OS, SPIN OS's type-safe linking for acceleration, Minix 3's reliability scheme, JX OS's architecture, Microsoft's verified VerveOS scheme, maybe even Amoeba distributed OS just for kicks to see what it could do today. Lot of stuff that might be better than Linux model with a Rust implementation in terms of reliability, security, extensibility, or developer productivity.

Just a thought for Redox author or someone else wanting to try an OS in Rust. However, best thing to come out of Redox project, imho, isn't the OS so much as this article:

https://redox-os.org/index.php?controller=post&action=view&i...

Great write-up on an equally great strategy of developing with hardware that's well-supported by both native OS's and virtualization. That's worth copying and expanding in other projects. Maybe worth a dedicated list like the HCL's where there's a list of computer builds that are easiest to develop on with or without virtualization. Or list it one piece of hardware at a time.

Yeah, I suspect that was a big part of their thought here -- USB-C charging is very fast, and whatever marginal convenience win you get from wireless charging would almost certainly be overshadowed by the speed of wired charging.

The upshot of BTC is that there isn't a real governing body that has political goals. If you're in the euro you've effectively outsourced monetary policy. With BTC there isn't any.

Expectations are a huge deal when dealing with money as that's the only thing that gives it value; other people's expectations. So if your currency is one that everyone expects to fluctuate wildly over time they will behave differently than if they expect it to be very stable.

Well if there is editorial independence, will we still see posts for when YC companies are looking to hire people, where you can't leave a comment, I am guessing for fear of creating noise that is not helpful to the hiring process?

And will YC companies still get what appears to be preferential placement ("appears to be") for stories? [1] Some "more equal" than others?

If this is true independence then those benefits would be extended and/or eliminated.

[1] Or do stories about YC companies simple get more upvotes because of the balance in the community here toward people working at YC companies?

I'm not sure I agree with you there. Doesn't the term "editorial independence" come from newspapers? Those always had ads.

Indeed the nice thing about the current arrangement is that the YC startup job ads are completely up-front, always work the same way, and have a fixed effect on the front page. So it doesn't affect editorial judgment at all. (Except that we try to take linkbait out of the titles and I'm surprised that no YC startup has asked us about that yet.)

Never ever reveal it. It WILL weaken your negotiating position. You will very likely get a worse offer and worse ultimate package by revealing any previous compensation info, and recruiters know this. Experienced recruiters have people being reluctant to reveal this information, and have experience pushing back on it. Practice being nice and still not revealing it. That is important.

If they only will go on with the process if you tell them past salary, move on or make a choice- you really want this job, and will take it for less money because of the experience/ location/ technology/ coworkers/ environment/ etc.
>supportive government

And which one would that be? This is kinda the problem. The Greek government is so rotten people don't pay tax to it if they they can get away with not paying.

Some governments make their citizens rich, while other ones make them poor. Greece's definitely belongs among the latter.

I'm sort of a socialist and my hypothesis is that society benefits from good governments being big and bad governments being small. Greece's government is horrible and should therefore be tiny.

Constant time means the time, expressed in the number of steps the algorithm takes, doesn't vary based on the size of the input. The time to reach the relevant memory doesn't vary on the size of the input, but rather on the topology of your architecture. Further elements may well take less time, depending on where they're actually stored, so you can simply average out memory access to get a constant factor.

Now, if the number of times you had to access the memory in order to retrieve the data in the array depended on how big the array was, then you'd have O(N). An array is specifically designed so you only have to go to memory twice, first to get the memory address stored at X position in the array, then to retrieve the information stored on that position.

A linked list, as described in a sibling comment, actually does have to do this. You trade easy accessibility for other properties.

Ditto for the steps to do register operations and any of the other machine language instructions. The time can vary, but not as a function of the size of the input. So it's still constant time.
I found some more background here[1]. It's not clear (to me, at least) whether Euler would have employed parentheses in that case if they hadn't been necessary to avoid ambiguity, i.e. if the argument had been x, he might have just written fx.

Arrrrgh, so much promise...
Yeah, I know the story. The result shouldn't surprise anyone, the swap approach works only if there are enough swap stations so that buying a battery-less car makes sense.

As long as all Teslas come pre-equipped with a very expensive battery, it makes little economic sense to let it depreciate while you are paying to use another battery.
You are right, and then it becomes a genuine question of accessibility. I wish the deployment of IVR were specially reserved for these markets - my sense is that IVR is still seen as a hip cost-saving measure even for companies in markets where internet access is easy and plentiful.
You could say the same about gasoline, yet MPG varies widely across vehicles.

On my EV, I can drastically change the battery's range (from 80 to 120 predicted miles) based on driving behavior, much of which could be "shaped" by software. "Softwareing" 50% more distance out of that stored energy matters.

That's lighter than some pickup trucks. A modern single cab 8ft 1/2ton 4x4 usually comes in just under 5000lbs (curb weight). Variants with longer cabs are usually in the low 5000s. Single cab 8tf 90s pickups come in in the low 4000s.

Sure you could dump an extra 1200lbs on the Tesla but you'd have to strategically dump another 300lb of metal at the vehicle itself if you want the chassis to last.

I couldn't find part numbers for any wearable suspension/steering parts so I can't compare t to other vehicles but I'd bet that the chassis is very finely tuned to the weight that it has to carry and that there's not much wiggle room for extra while maintaining a the designed life expectancy.

I couldn't find anyone talking about replacing long-term wear items (I didn't look hard) which does seem to indicate that they're overbuilt. I can see why Tesla may want to give people a good impression of EVs and not want to take the risk of using anything but an overbuild chassis on which to make that point (the Chevy volt on the other hand...)
nah, I don't think of flag/vouch as the same as upvote/downvote.

Regardless of the constant arguments around it, I use upvote/downvote on opinions I agree/disagree with. I'd use flag/vouch for things that I don't/do think should be on HN at all.

e.g., on a Pokemon forum I can strongly disagree with someone who says squirtel is the better than pikachu because water-type has more advantages that electric-type. I might downvote it, maybe. But if someone posts "Pokemon are stupid, you're all wasting your lives you big losers." ...I'd flag that. Conversely, if I posted how electric-type pokemon are the best and I notice a dead-reply to me explaining very clearly a position supporting water-type pokemon as best, I'd vouch for it. While I might not agree with the argument, I can at least vouch that it shouldn't be dead.

In particular, the mathematics courses US engineers and accountants take are mostly unsubstantiated symbol pushing (warrant: find me a calculus student in the US outside of Chicago or a few other places who can prove the fundamental theorem), which isn't mathematics.

When you decide that only one place in the US has any idea what mathematics is, then this discussion is not going to go any further. I guess Harvard, MIT, etc. don't count.
It takes longer to access elements that aren't in cache, but that's still a constant factor. It may be 100x or 1000x but once you're going all the way to main memory it's not going to get any worse as your array gets bigger.
