Ask HN: Is there any up-to-date guide to resources for learning iOS?
I know I could google the answer myself but I get so many different opinions and recommendations on this subject. So, I'd like to ask the trusted HN community. I basically need the first three resources which are up-to-date and I should check out right now. About me: I am not new to software development and dived once into Objective-C for some weeks (but years ago). Thanks.
Not hardware per se but bridges between real and virtual. Streetview is in that category too for example.
I'm not sure I agree with his premises (so, I also don't agree with his conclusions).

A cheap, slow, bottom-of-the-line 128GB SSD (with lots of negative reviews on Amazon[1]) is $85, and Apple is charging $250 (the author lies at the end by calling it $450 to make it more sensational!) for it, so that's evil? And anti-consumer?! How about Fusion Drive's seamless integration with OS X? How about the fact that it works as a "single" logical drive (which is preferred over multiple logical drives if you were to purchase HDD/SSD separately)? How about "you don't have to worry about putting which file, where"? That's not worthy of putting in your BOM - only hardware is worth paying money for?

If it's just a minor software tweak, then I (in good heart) suggest the author to quit his job and create an equivalent for Linux/Windows and sell it for half what Apple sells FusionDrives and make a huge amount of money.

I've been wanting to buy one of those shiny Seagate Momentus XT ($180 for 768GB version) for almost two years I think, but apparently it's not good. The firmware is buggy as hell, especially for Mac. I remember there was a thread on Seagate's support forums with like a thousand angry messages, and after 2 months someone from Seagate told that "they're reaching out to some select customers to iron out minor problems that some people were having" and it took them months (again) to fix them. So it's not like "fusing" HDD and SSD is a solved problem...

Bottom line: We pay Apple, Google (well, indirectly), Intel and others to make decisions for us. I can buy a (slower) $85 SSD, put it in my Mac Pro and try to make it work like a fusion drive (which, contrary to what the author said, is not a caching mechanism!), or I can give Apple $250 for something that's better than that and be sure that my data wouldn't be removed because of some stupid configuration (and save hours of maintenance). I prefer paying for the service.

Edit: I love this comment from the article: OMG… The parts in a Ford, and the parts in a Mercedes cost almost the same, but Mercedes is RIPPING OFF customers by over-charging!

Edit 2: I forgot: The author clearly doesn't understand what FusionDrive is, and still thinks it's a caching system! (despite apparently reading the Ars article (that gets the facts right) and* the ExtremeTect link-baity article (that got the fact terribly wrong, but later corrected the article at the end)*.

In the filter section I would make it possible to search with a range of values in "age" and "height" instead of only accepting one unique value
No, I just remember listening to the investor calls over a couple quarters & she was unable to give a straight answer on either issue ( WebOS, PSG)
The article mentioned that the pin layout is the same, only the shape is different, so I don't buy the performance explanation. It's a change so that they're different and not the first one.

Claiming something vaguely true may be marketing. Claiming something incorrect and calling it marketing is at least dodgy.
The problem is this is a little disturbing and honestly pretty unhealthy; i.e. I think this would lead to some kind of burnout or breakdown either mentally or physically. Sure, it seems like an awful lot of work for the ultimate reward of working at Google, not exactly like winning the Nobel prize or something.

Earning energy drinks for performing tasks that seem to almost require energy drinks in the first place seems to be a scary feedback loop. I think the other major issue with this is your treating yourself like some kind of machine or simple animal that performs tricks or that runs toward dangling carrots. If you have the discipline, which I wouldn't, to stick this burnout game, it seems like you should have the discipline to take a more reasonable and measured approach to doing an appropriate level of study/preparation without all this stuff. And all this business of mechanistically surrendering yourself to progress bars ... I think people that go to this extreme need to study more humanities and learn more big picture kind of things; this is like describing behavior one would find in characters in some dystopian novel.
Hi Paul, thanks for the reply!

I wasn't judging you guys on the 'pictures' at all. :) Was just giving some candid feedback from my experience. I actually signed up write after I wrote that, and was going to post again once I'd had a chance to try it.

I did get to try it briefly and I actually think the UI, while simple, is better than the other (albeit much more complex) solutions I've been looking at.

>FYI: we hate the "write to my private repos" thing too, but with GitHub's permissions model there isn't a better alternative (there are alternatives, they're all bad).

IMO, this would be a big improvement and is doable: let me sign up (still via GitHub auth) without asking for the repo or user scopes. Then have a call-to-action that upgrades the token, as part of the guided welcome into Manage Repos. [I realize this could hurt your funnel, perhaps offer this path buried in the FAQ somewhere if that's a concern]

If you pass nothing for the scope param to the GitHub API, that gives you the authentication piece with read-only access to the user's public stuff. Then just add a "Hey, we can only see your public repos by default - click here [..]" that sends them into the web flow again with the additional scopes, to upgrade your auth token.

Also, while I'm giving unsolicited advice :) - it may be obvious, but letting the user know that when they follow a repo (and just doing this on the first repo they use would be fine) that you're going to add an SSH key would probably be a good addition. Since adding a deploy key sends an email to all admins of the organization, some users might want to give people a heads-up they're trying out Circle.

. . .

Anyway, Circle looks great already and I'm eager to see what other stuff you guys have in store. I'll certainly be using it for some of my projects.
One language I used in the past (Pop-11) made a very deliberate pedagogical decision to not have errors or exceptions - it had 'mishaps'.

I don't know about it (so it could be wrong), but someone at the comments section said:

Another point is that Apple’s SSD connector is different because they are already selling SSD configurations up to 768GB, while the current maximum for standard mSATA is only 256GB.
Kalpakkam, India has already been in works for years! The design for it according to wikipedia had been started in the 80's.

"Nuclear power is limited, there is just not endless amount of uranium on the planet."

A finite quantity can be quite large. Uranium is not that scarce even with a ramp up of nuclear activity. And even then, there is thorium, a more abundant fuel.

"you can't usually use the heat an nuclear power plant produce for anything productive, so it's lost."

That is a problem with conventional low-temperature high-pressure designs, however LFTR (low-pressure high-temperature) produces high enough temperatures to be usable in industrial processes directly (700C). Designs can be modified to get to 1000C or so which is useful for hydrogen production.

"But of course there are new and better plants in development, they are safer and bigger and produce less waste."

LFTR not only produces less waste, but it can be used to burn existing waste. So if we consider the costs of long term security and storage, just developing LFTR to process waste is going to be worth it.

"Since 2005, there is a nuclear power plant being build in Finland, called Olkiluoto III."

That is indeed a problem with all large industrial/construction projects that need government funding or complex regulatory processes. If you are arguing against nuclear power you should be against all such projects.

One problem with wind power is a poor ability to provide base grid load. Yes, if you have a widely distributed (continent-wide) network things may even out. But then that means you have to waste energy in the transportation network, as well as investing in powerlines. The same argument about inefficiency starts to come up.

The main argument then for wind and solar is that the costs scale linearly with output, whereas for a government-backed power plant the costs tend to escalate (bribes, kickbacks, cost-plus etc). That is acceptable, it just means people can become more independent of the inherently inefficient state-run grid. But with a state-run renewables system you have to contend with a centralized and potentially oversized grid. You trade away centralism in one area (identical turbines or panels) and have to buy it back in another (large scale power distribution system).
The title is misleading. They only test thorium in an already built conventional reactor. Meanwhile in Germany they developed a conceptionally more safe reactor type powered by thorium, built a test reactor (http://en.wikipedia.org/wiki/AVR_reactor) and an industrial reactor (http://en.wikipedia.org/wiki/THTR-300). They're both shut down now, partly because of safety concerns: Water leaking into the cooling circuit can lead to explosions (which happened in small amounts)

So I guess only time will tell if new reactor types really are better than current ones.

When a Woman Turns 40 And Why It’s The Best Time For Career Changes
When they take away opera they will take away firefox, then they will take away the next one. One day we will all be using chrome.

I think they should warn about compatibility but allow us to proceed anyways. Often when I spoof opera to identify as firefox everything works fine. The `built only for this browser` scheme treats the browser as the platform and not the internet as the platform. I understand the practical motivation for perspective, having spent many hours making sure my design worked in IE and Firefox, but I dream of a world where every-browser will render things identically.

Ultimately, its called a webpage not a chromepage.
This is admittedly poorly executed and doesn't really follow a lot of metro conventions.

This article is a piece of shit.

1) It explains nothing about how Fusion Drive works. In fact, it muddles the waters by likening it to SSD cache technologies, while it's simply not a cache at all.

2) The sources it links are speculation posted right after the announcement, when no technical details were available. Of course, the details have since come out and have been analyzed in detail, but the writer ignores that.

3) The custom SSD connector on laptops has absolutely nothing to do with Fusion Drive, since FD is offered on desktop machines only. The Apple laptops that have the custom connector come with pure SSD storage: there is no spinning HD to use for FD.

4) But at least that gives the writer an opportunity to claim that the custom connector makes it impossible to buy upgrades from third parties... only to then mention a third-party that makes compatible upgrades in the very next sentence. What?

5) You can use Fusion Drive on your entry-level Mac mini or iMac, actually. In fact, you don't even need a new Mac at all, and there are no hacks to do: it's all right there in OS X.
ill-regarded desktops, laptops

While their consumer and low end stuff is pretty crap, Their top end line of workstations (Z-series) and laptops (Mobile Workstation) are pretty good. We use them at work and they are certainly no worse than anybody else and better than most.
Pretty slick. I like how simple it is. Does a good job solving the cold start problem. It's fun to look through stuff and come across things I'd want to add.

The share area on the left-side keeps overlapping the left set of tiles. Makes it hard to read.

The contact us link doesn't work. This might be because there are other JS errors on the page.
Actually they seem to give you more ssd space than need. Compare it with lenovo which throws in a 16gb ssd drive for free. I've got it set up as a writeback cache (using flashcache) and honestly don't see a performance difference compared to the whole system being on the ssd. (of course the difference is there, just not noticeable anymore)

That doesn't really match apple's $200+ - lenovo can do it for free to some extent.
Germans have more than one goals: more renewable energy (to replace conventional power plants) AND no nuclear. The latter is not optional.
If you copy what he's doing in those tutorials, you will learn something. If you just copy someone's code by typing, you will not. That's the difference.

Or are you saying you can't even follow the exact steps in that tutorial to result at a very similar image?

If you just read the tutorial, you won't learn much about drawing. He could explain all the choices he made, and you may feel better about knowing that, but the end-result will be initially about just as wonky as it would otherwise have been.

I`m not talking about haxe in genereal. I have nothing against it. I`m talking about the idea of NME which is really nice but would fail in many (higher performance visuals) cases when it comes to javascript/canvas.
To me it seems that taxing unwanted effects is far better than subsidizing good techs. With the taxing scheme you are not endorsing a single technology but are attacking the root cause of your problem.

For example, would coal powered power plants be a problem if they didn't produce greenhouse gases?

Nuclear waste is the problem? Put tax on nuclear waste and raise it until the tech is either abandoned or the problem is solved.
Yes exactly. Has it been done or studied?.
The US had a ban on reprocessing nuclear material and the industry is currently not commercially viable. However, other countries (France and Germany) do recycle their nuclear material. This can help reduce the amount of nuclear waste.

The most worrying angles seem to be human factors issues: the lack of coordination between drone crews and airport ATC, and the apparent deficits in training/qualification of pilots.

"Similar accident rate to F-16s at a similar time in their development" doesn't fill me with joy either; combat aircraft can expect a crash or major incident on the order of once per 10,000 flying hours, whereas for airliners the equivalent rate is roughly one crash or major incident per 10^7 hours -- three orders of magnitude safer! It's like comparing over-powered motorbikes in the hands of reckless teenagers with school buses.

The original justification for deploying drones over manned aircraft was that the drones could be built cheaper -- no expensive aircrew to risk in event of a crash, so less need for complex safety systems and multiple redundancy. Now put this cheap, cheerful, and not terribly safe device in the hands of a lowest-bidder contractor's hired help, who may or may not have been hired because they were cheap rather than able to do the job ...

And now imagine the bikers in this metaphor are riding on a stretch of road used by buses, are ignoring the traffic signs, and that a crash will kill everyone involved (including the full bus), and you've got a grasp of the picture we're looking at here.
Concorde has a max speed of just over Mach 2.0. Hypersonic means Mach 5.0 or higher. The rocket-powered X-15 max speed was 6.7, and of course the Space Shuttle also went faster than Mach 5.0, so yes, humans have already flown at hypersonic speeds.
This is very strange. Why are military "contractors" flying these things ? Should they be trained military personnel piloting the drones ?
Awesome! Really glad you like it!

The share area, we agree - we'll remove that.

The Contact Us part does actually work but we've not made it v clear so we'll adjust. When you press it, if you look closely, you'll see a new tile appear (top left) that says 'send us an email' - it's not clear enough though so we'll look to adjust. Thanks.

And yes, Fusion drive is effectively a caching system.
In this case, the article is clearly a piece that's advocating coffee drinking. When research crosses over from "setting up and experiment and proving/ disproving a hypothesis" to "advocating something as good or not good in general", its important to look at the source of funding and apply a heavy discount on the validity of the research if its advocating "for the money".

This is not research "related" to coffee, so your hypothesis is not valid in this instance.
If I am correctly informed (would love to hear from people who are involved in the project), this project is being done in spite of the Norwegian government's stance on nuclear energy.

Thor Energy and its associated researchers have tried to stir up support for thorium reserach for years now, but there has been very little support and large amount of uninformed opposition ("nu-cu-lar is baaaaaad"). A number of physicists, notably Egil Lillestøl at the University of Bergen, have talked to official figures about this for a long time about this without getting any kind of traction.

Thorium energy seems to be a very promising candidate for safe, clean and cheap next-generation nuclear power. If these researchers manage to develop something without official support, it would be impressive indeed. That the Norwegian government isn't willing to support clean energy research is really quite baffling, given that the energy sector is hands-down the largest contributor to the Norwegian economy. And Norway has the world's second-largest known thorium reserves. For all our supposed good policies, we are still subject to mob rule and completely uninformed detractors.
I think 9/11 was coincidental and unrelated. The important trend in 2001+ was the growth of telecommunications phenomena that reduced travel demand. I am not sure if the sonic boom was nearly as big a problem as it was made out to be. I think we can do some cursory math.

If 30% was at 50% of the speed, the total distance covered would be 85% less, adding about 20% flight time increase. Something that normally takes 8+ hours now take 3 or 4 hours. Did this kill the concord?
Python has two types of statements; "simple" statement and "compound" statements. Compound statements are those, like the if- and while-statements, which require multiple lines.

Only simple statements may be separated by a ';', not compound statements.

This is a bit different than what you wrote. For example, "x=4" is a statement, and not an expression, but "x=4;y=5;z=6" is a valid Python line because assignment is a simple statement, and multiple simple statements may be separated by a ';'.
I'd be curious to hear an explanation of when you should or shouldn't do this. It's interesting to see stackoverflow as an example of bowing to community wants, because stackoverflow seems like the ultimate example of not doing that. The most upvoted topics are closed for being the wrong kind of content, and most of the questions that were, historically, the mosted upvoted would now be closed before they could pick up steam.

I can't be the only person who notices this; pretty much HN post that features SO includes a litany of complaints about them. Even if the original post isn't a complaint, the top thread in the post will probably be a complaint, regardless of how relevant that is to the topic.

My point isn't that what SO is doing is wrong. It's that what they're doing seems to go against the wishes of the vast majority of the community. Jeff even links to a post of his that basically says "you shouldn't always listen to the community". So, when do you listen and when do you ignore? Advice that consists of "sometimes you should do X and sometimes you shouldn't" seems trivially true for pretty much any real-world X.
Ask HN: British Government has "Blocked" Pirate Bay, How?
The British Pirate party is running a proxy for pirate bay at the moment and have been asked to shut it down by the industry body. they were running the proxy because the site has been blocked by court order from the within the UK. Out of interest yesterday I googled and arrived on the Pirate Bay, from within the UK. I'm using OpenDNS, have they just demanded that British ISPs block the pirate bays entry? That seems a little simplistic to me.

I can't view the oracle link (http://www.oracle.com/splash/rpls/embargoed.html) - it's something enterprisy I'm sure, so it's even more expensive than FusionDrive (with much better support and more features), but the Linux thing you linked is a caching system, which FusionDrive is not.

> Fusion drive is effectively a caching system.

Oh... No, it's not. It's a block-level tiering solution which (mostly) promotes important "blocks" automatically and intelligently when computer is idle (so as not to slow things down when the user is working).

Very, very different from caching, very different technology (Apple has been working on CoreStorage, Apple's logical volume manager for years).
