IPython has been great for me doing statistics with students' assessments. Though I only deal with several hundred students I can get pretty quick results working with IPython.

Personally I like IPython qtconsole. It is basically a terminal with all the graphics turned on. Not as feature rich as the IPython notebook but it is faster and cleaner for what I use it for.
IMO, while it's nice to own a copy of a book that looks good and doesn't fall apart, the awful thing here is not the cosmetics but the fact that the copy is a mangled-up version with errors that have been fixed in editions over a decade ago.

You need to be able to trust a book. I received a misprint of a book I ordered online once, duplicate pages, missed half a chapter. I didn't need that particular chapter for the course I was taking then, and it was a week before the exam so I didn't send it back, it's a really cool book (Computational Geometry) that, like other interesting study books, I would pick up again and browse occasionally, if it weren't for this mess up. It's a shame, really.
There are some CEOs who think they can do anything, and design logotype over the weekend.

There are other CEOs who think they can do anything, and start their own space program (with an electric car company on the side).
I don't think there's an answer in that there is no answer to backdoored hardware. Someone recently demonstrated how to reprogram the controller on hard disks (they're ARM based SoCs) to monitor/modify the data. No one is going to come up with an alternative open source hard drive.

As to software, whenever the topic comes up, someone shouts out "OpenBSD!". Unfortunately, it's by no means beyond US pressure, at least at the individual developer level. The whole "FBI IPSec backdoor" fiasco a couple of years ago is tacit acknowledgement by the OpenBSD core that such a thing is possible.
Long time coming. India (which is a pretty huge country) did away with roaming (incoming call) charges back in 2003. What followed, was a telecom revolution; albeit with the evil of corruption along the way but good did come out of sensible and foresight.

I love RTSs. Total Annihilation (TA) was an early favourite.

SpringRTS is an open source game engine that improved beyond TA and actually had UI features that Supreme Commander has drawn inspiration from.

The multilayer is epic, its totally LUA scriptable. People have re-purposed that engine for all manor of weird RTS type games. I sincerely hope this project is going to use that battle hardened, cross platform, actively developed, open source RTS engine rather than roll their own.

Was the link I gave, about not allowing pre-sales for items that won't ship within 20 days, not clear enough?

It's not some little footnote hidden within a wall of legalese. It's a pretty clear statement of what they allow and what they don't.

And why would you think that crowdfunding counts as "apparently-innocuous"? Crowdfunding is an area that is ripe for scamming. You create a glitzy campaign, get lots of backers, keep promising something that never quite gets finished, and then disappear with the money.

Apparently, ever since the Ubuntu Edge crowdfunding campaign failed, there's been a whole bunch of fake knock-off campaigns, of people capitalizing on the interest and trying to trick people into funding things that pretend to be related but really aren't.

Any time you have some kind of "amazing new investment opportunity", there are going to be scammers. And when you get down to it, crowdfunding is just an "amazing new investment opportunity".

That is exactly the Point. Spectrum is scarce, and just like land areas are treated(mostly) with property rights, so should radio waves. That it historically has been mistreated doesn't make the solution in the subject any better.
I'm of two minds on this piece.

On the one hand, the author is absolutely right that a good professional designer can bring things to the process that enthusiastic amateurs cannot. A really good logo doesn't just look cool, it communicates something about the nature and spirit of the company visually. It lays down a marker: "this is who we are." A designer who knows the grammar of visual communication will have a better chance of delivering that than will someone who doesn't.

On the other hand, the author sadly doesn't do a great job of arguing the above point. Rather than, say, taking some great logos and pulling them apart for us to show how they do what they do, we just hear a lot of complaints about how the way Yahoo did theirs was "unprofessional." It makes it sound like the main complaint is that Yahoo had the gall to cut designers out of the process rather than that they chose a path that was more likely to result in a crappy logo, which strikes me as a more powerful (and accurate) complaint.

In other words, outside the community of professional designers, nobody cares if Marissa Mayer hurt some designers' feelings. What they care about is how Marissa Mayer is stewarding the Yahoo brand. If you want to convince them that your way is right and her way is wrong, don't show them how her way threatens your business; show them how her way threatens her business.

I spent at least 10 years doing development on my own before university and it never once occurred to me to read an algorithms book. Funny enough, that turned out to be one of the best courses I ever took.

I think with the rise of MOOCs though and the offering of algorithms courses for free online, such as at Coursera, there are going to be a lot more developers without formal education who are familiar with algorithms.
In the UK there is a scheme called SEIS (Seed Enterprise Investment Scheme) which gives investors 50% tax relief on equity investments up to £100K per annum. This is great for startups, as it has resulted in a lot of people investing for tax efficiency (and hence why most angels look to invest up £50K in any single investment, so that they can spread the risk); however, the side-effect of this is that a lot of people who would otherwise have simply invested in markets have become 'angel investors'. Joining an investment club seems like a sensible idea for these investors, however they often lack the experience required to understand (or indeed empathise) with the entrepeneurs they meet.
> HN should be able to tell the difference between good PR and good tech.

You know what? I make an exception to that in Elons case. There are plenty of people who do that and who leave us pretty much where we were before. Think of the tons of Microsoft Research projects that are mighty cool and are thrown in our face every half year or so... but never go anywhere expect right in the basket of "well, I guess Microsoft isn't entirely dead, yet" PR.

Is this extremely exciting stuff in itself? No. But it is still exciting to me because I know if Elon does it, he will follow up and make the best of the opportunity. It is the marriage between the person and the project - in the Microsoft example, some, probably mostly PR, division comes up with "oh, I suppose that's neat" on a regular basis, but what they do has no direct link to any real life implementation. What you need is that connection of being able to dream big and execute big - and for that, the impulse has to come from engineering, not PR.

It's like knowing that Carmack is hooked on VR goggles. For some things, the person doing the thing really makes all the difference in the world.
I often forget how big the US is.

But the government builds roads, and taxes[1] some road users. It's in the government's interest to provide some kind of infrastructure for lower carbon transport.

Providing a few thousand charging points for electric vehicles seems a reasonable thing for government to do, so long as those are vendor-neutral and can be used by any electric vehicle.

No there doesn't "need" to be. It might be useful to have a list describing owners of different wavelengths and in what areas, but until there is a dispute, there is no problem. If a dispute arises, it can be taken to court, and the right to ownership can be settled. Such disputes can be settled like any other property right disputes in court.

Why? The next Instagram with an Instagram number of users would definitely not be using Parse, but the whole point of the text you are disagreeing with was that Facebook could use the data before the next Instagram fully exploded with users.
Mice already let you do everything he's doing there, just as easily and with more precision. And most 3d modelling programs still provide a standard setup of orthographic views. Modelling in perspective is really difficult and inexact. It doesn't matter how you're interacting with it, perspective is just a bad way to deal with complexity and precision at the same time.

If you look at things like z-brush, that are modelling for things where precision isn't as important, generally organic/character modelling, they do tend to work better in perspective and come up set up that way by default. But anything that needs precision, which engineering does...

The best critique I've heard of the Leap interface is that human hands are extremely proficient at manipulating small physical objects.

But without any kind of force feedback, manipulating images using the Leap is neither simple nor easy.

You must become like a good mime, and that takes a lot of practice and is very counter-intuitive.
For end users, this is rather difficult. I maintain a Jetty web server, which is based on Java. The SSL/TLS implementation relies on the cipher suites provided by the JVM. I can restrict Jetty to using ECC as preferred cipher suites but not choose the curves. I assume this is also the case for many other web servers out there.

On the other hand it is easy to avoid ECC altogether in this scenario.

EDIT: Grammar
BTW, to be clear, your article made me look closer at this sort of rhetoric ("lean in" and "break things") which I failed to learn about before, because I gloss over it like meaningless startup names. Thanks.

Yahoo!'s challenge isn't their logo. Yahoo!'s challenge is ensuring their brand becomes associated with whatever they do best.

When I think of Google I think of search, ads, and Android, and GMail. When I think of Microsoft I think of Windows, Office and XBOX. When I think of Apple I think of the iPhone, and the iPad. When I think of Facebook I think of photos and privacy (lack thereof).

When I think of Yahoo there's no defining correlation to anything. I realize many people frequent their services - but personally Yahoo! doesn't stand out as "best" for anything, and I don't even know what direction they intend to pursue to change that perception.

Ha, I just wrote something very similiar about this:
http://www.techdisruptive.com/2013/09/04/logo-doesnt-matter/

No, it’s not getting attention. It’s gaining trust. Ironically, for that you need a reflective, clear, and consistent brand identity. A different logo powered by bullshit doesn’t convey identity and trustworthiness. It conveys desperation.

While the overall sentiment of the article is sound, I slightly disagree with this. First, this whole story of "creating the logo in a weekend" with an "intern who did some motion graphics to convey it's uniformity" is pure and simple, a publicity stunt, and a good one at that.[1] Personally I don't think there is an intern named Max who did that (most likely an agency), but this subtly conveys the perception of something that Yahoo is missing - innovation by small teams. The reality is that Yahoo does have a brand problem (just as MS does in the consumer-mobile space), so they have two tactics they need to implement in order to properly manage the brand:

1. Change the perception of the brand (changing the logo to match the new found brand perception is a good way to do that)

2. Create buzz around the fact that the perception has now changed.

Marissa's plan for the logo did just that. I think it's a good strategy and something Stringer Bell would have been taught in his business class.[2]

Ask HN: Good Alternative to Dropbox?
Hi All,

Recently I've been extremely disappointed by dropbox to the point where I've had to reluctantly delete my account and look at alternatives. I was hoping that you guys might be able to point me at a cloud storage solution that copes well with large numbers of files (>300k) on mac at a reasonable price point + preferable allows you to manipulate large numbers of files on the server side (through a web interface or alternative.)

An important note - it's very easy to get to large numbers of files if you ever a. store open source code you're playing with in your cloud solution, b. use git (it generates a lot of files.) - so 300k+ files isn't as outlandish a number as it sounds.

Background for those that are interested -

* I noticed the client was using 100% CPU and never seemed to enter the 'synced' state. A google suggested this was due to too many files, + a reinstall/cache clear could fix. Did this.

* 1 week later - No change. Contact support and received boilerplate copy/paste replies telling me it was too many files + either remove files/use selective sync. The latter crashes dropbox. Did the former.

* Several days later - no change, so send another email whereby I am told symlinks are the cause, despite the fact they've worked for over a year. I move all code (node_modules contain symlinks typically) from my dropbox leaving ~20k files left in there.

* Several days later - Still no change, so I try deleting files on the web interface. It won't let me delete a folder with more than an unstated number of files in it. Support suggest I manually delete 100's of thousands of files.

* Dropbox client starts overwriting files as I work on them.

* Support staff stop responding to emails.

The dropbox client could have at least warned me about the files, if this is an intractable problem. No. Silent failure.
HN again has some depressingly negative comments.

It's good that there are people with the disposable income, and the engineering resources, to tinker with stuff like this.

This particular iteration may not be interesting to you, but we're stuck with WIMP (or WIMP-lite) environments very similar to the 40 year old versions. (More colours, more animation, bigger icons, but little actual change).

Kludging together desktop and mobile interfaces is being attempted (with a variety of horrible unpopular results) by many people, so it's great that other people are experimenting with other paradigms.
Eh, you can revmatch without heel-toeing. I did it for years before I started driving at the track and learned how to heel-toe. You just brake enough for the turn, then let off the brake entirely and blip the throttle and drop the clutch while turning.
In the OP video, Hack Reactor claims an attrition rate of 10% and a placement rate (as software engineers) of 100%.
In my experience with the Leap it's more important to learn the limits of the capture space and the device's sensitivity in the individual application than getting the gesture perfectly right. Another thing that people don't get immediately is that you're not signalling at the visual medium on the screen to perform tasks, rather, the screen doesn't matter at all. It's a sensory feedback loop adjustment that takes a few hours of tinkering around, but once you get it, you get it. The main problem is gorilla arm and the tediousness of some tasks, the latter of which will hopefully be solved in software. Check out the 3D skull explorer app if you get a chance, it's the best implementation of gestures I've seen for the Leap, actually usable. I could definitely see people who regularly need to manipulate 3D models using similar metaphors.
Others make the point about calling costs, but if you want data only (say for a tablet/laptop/mifi) an any-network roaming SIM would be very attractive. For example my current network is great in London, but has no signal at all in my hometown. It would also be handy for use on the train, where coverage on all networks is patchy.
