replax··on Walter Isaacson’s ‘Steve Jobs’
That is true, as people have ported Siri to the iPod Touch and iPhone 4, and it is performing exactly the same. Therefore, they either emulated a whole chip (highly unlikely) or everything is processed in the cloud/on the A4/5/#.
replax··on City Layout Design: A programmer's perspective
Surprisingly, I found it rather similar to Tokyo actually.

Tokyo, too, has multiple sub centres which are mostly self-sufficient. They are connected by a train running around in a circle and have central hubs where trains depart into the suburbs. Stations are largely accommodated with large bicycle parking lots to facilitate train usage. However, even though Tokyo is one magnitude bigger than NYC, the transportation fees are fairly high, too. Also, the Japanese solved the parking space problem, by making it a requirement to have a parking space in order to be able to buy a car.

replax··on A Schrödinger cat with eight lives: quantum entanglement of eight photons
In fact, the Copenhagen interpretation has been proven wrong by fellow lisper Ron Garret. You can read his paper here:

www.flownet.com/ron/QM.pdf

and watch his google talk about it here:

www.youtube.com/watch?v=dEaecUuEqfc .

The problem is, that most people (not scientists, mind you) do not really care anyway, and the Copenhagen interpretation gives you a nice story to tell, which is fairly "strange", yet somewhat understandable. I hate the fact that even science magazines still 100% subscribe to the Copenhagen interpretation, just to attract a greater readership and to be able to use catchier headlines.

replax··on The Pirate Bay's Peter Sunde: It's evolution, stupid
I have to disagree, piracy does not only exist due to bad business models. Back in the day, it was generally more convenient to buy a tape instead of copying it from a mate. While convenience/"bad" business models is a big part of the reason for piracy it is by no means the sole reason for it. E.g. people love collecting stuff, but could not rationalise to pay for it. There are people with multiple TB's of music/films/books/pictures that they never consumed, just because collecting it is their only interest.

Also, the Microsoft office Student example is obviously flawed. Office costs $300, if the student cannot/does not want to pay, he CANNOT USE it. There is absolutely NO business flaw on Microsoft's side there, except that their pricing might be a little to high for students. Maybe students are not their target group then. (I only use MS Office in this example because it is a response, students however can of course use the >FREE< MS Office (with ads) for their 3h-late-night-project).

replax··on Does Government GIS Data Belong to the People?
"Just to play devil's advocate, if the county builds a stadium for the local high school team, are citizen's entitled to free admission?"

Obviously you are missing the point, going to the stadium is the result of something being on show there, the "content". Therefore, it would not be free. What should be free (excluding maintenance costs which would need to be payed) is the usage of the stadium and actually it most likely is.

I know that in the UK I think there is a data liberation act or something similar, where you can request for data to be made available in public which was payed for with tax money. I think, however, that you shouldn't even need to ask.

If they don't want to publish the data, then don't pay for it with tax money...

replax··on MITx Opens First Course for Enrollment
I have this question as well. I read through the TOS, Honor Code and what have you but I did not find anything concerning re-enrolment/negative implications when not able to finish the course/drop out half way or be just really bad at it.

I would really like to do it and could most likely also take the time to do so but for me there is a possibility of something more important coming up in the future resulting in me having to cut back on the curse. If something like: "If you want to enter the next course/a different one and your record shows that you began a course which you did not finish, then you have to do X/will be given a lower priority etc." applies, I would reconsider enrolling.

Does anyone have any further information on that?

replax··on Ask HN: How to move away from Gmail
If you are lucky (fast) to get one of the first raspberry PIs, you could host your own mail server on one of those. Put SpamAssasin on there, get ssh running and the other mail programms you need (plenty of guides on the web for that), set up a rsync script for backup and then it's pretty much set & forget. Then when the SD card dies on you, you stick a new one in and resync, ta-da!
replax··on Poll: Would you pay for a RSS reader?
From the screenshots I'd say that you are talking about a Desktop/Web application?

In that case, It'd have to be significantly better than e.g. Google Reader (which got a little crippled unfortunately). Personally, some of the most important features would be, that it has colour schemes (e.g. like the Vim Solarised scheme) and allows offline caching/easy, good e.g. pdf export.

However, I have to admit that a decent mobile (iOS, WP7, etc.) Application would be of much greater interest to me, as that is where the advantage of a RSS reader significantly comes into play due to the much more limited screen estate.

replax··on Ask HN: I want to be a game developer. What should I do?
I agree with the suggestions already given.

Just to throw another idea out there, a further alternative would be to work/look at open-source games. Technology wise you are definitely in the correct direction, most common languages in game dev are C++ and various scripting languages (from my experience).

I have no idea how much time you have or what sort of stuff you want to do in games (e.g. graphic/sound engine, networking, ai...) but since you mentioned FPS games, you could look into Xonotic. It is a fast FPS game, open-source and based on a heavily improved Quake3 engine.

That might give you a better idea of what components make a game and you will not have to worry about artworks etc. if you want to contribute/fork.

But I figure, while contributing to open-source will help you understand games better, it will not get you hired without networking I think. You can also check out the SIGGRAPH convention presentations, lots of interesting, although maybe too specialised, stuff there.

replax··on We are sorry
Actually, in the blog post by the guy who discovered that, he said he was able to read the data - meaning that it was transmitted NOT encrypted (please correct me if I am wrong).

Also, I hope that their "industry standard" firewall is better than their "industry best practices" data sharing practices.

replax··on Magnetic recording breakthrough reported
Yes, you're right the world is going mobile and in mobile less (no) moving parts is better (more durable etc.) That is also why I think that consumer grade devices will be unlikely (unless read speeds are bumped up, too)

But mobile, in our case, means also a shift to the cloud, where significant more potent storage technologies could make a real difference. I really hope, too, that technology will lead to something new.

replax··on New Linux kernel fixes power-saving issues
Same for me, I have an x220 using the 6cell and get around 3h on Windows and about the same on ArchLinux... Broken battery?
replax··on Magnetic recording breakthrough reported
In response to your question on availability in commercial HDs, I think that unless a comparable significant advance is made in read speeds, I doubt that you will find it in consumer grade HDDs soon. A disk that can read at e.g. 100mb/s and write at 50gb/s would be not easy to sell to the consumer at a premium price (where do I get data faster than my HD/SSD read speeds from to store?).

I assume though, that it might be used in e.g. CERN, where they need to store a ridiculous amount of data in very short time. Or similar activities where the write speeds are the limiting factor.

replax··on Magnetic recording breakthrough reported
Well the article mentions that:

"This revolutionary method allows the recording of Terabytes (thousands of Gigabytes) of information per second"

Therefore, If you can write 1TB/sec the seek it would pretty much outperform any SSD cluster, in terms of writespeed. unfortunately, nothing is said about read speeds/access times and I assume that that will be a harder problem. Because they are still storing the data magnetically and the platters don't emit heat based on their polarisation, they still have to pretty much read like normal hdds do. You cannot (until now, like it was not possible to alter the magnetic polarisation of metals other than with another magnetic field) sense the polarisation except for with another magnetic field.

I am really interested in how that will turn out, but before they make a significant advance in read speeds I doubt that the technology will make it into consumer grade HDD's any time soon.

replax··on Show HN: Weekend Project - SSD Price Tracking
Hey there, I like the idea, it is a very specific site for a single use. Obviously there are other sites doing the same thing already. I like the clear, up-front approach (design), however I feel that it is too minimalistic.

e.g.: where did you get the numbers from? Amazon? Price comparison engines? Crawl the web yourself? At what rate does the site update? How are the ssd types maintained?

Few suggestions for future features if you want to continue working on it:

- Let the user add/submit missing ssds.

- Include an amazon affiliate link (convenient for user & might pay for your hosting)

- Instead of filtering by absolute capacity, rather let the user filter by a capacity range

- add msata as interface type

I really like the site, keep it going!

replax··on Windows Phone 8 Apollo detailed, will have Windows 8 integration
It's been announced (was some days ago on engadget), that native C++ support will come with the next update. Not sure when that will be as I did not dig deeper into it, but I assume it's rather soon.
replax··on Id Software Open Source releases on GitHub
I agree that it is not the best comparison. It is the best I could come up with... The problem might be that I compared out of context - a texture is not very different from a painting (in theory, physical anomalies aside) - I did not intent to compare paintings to complete games. However, the interactivity results from the combination of the textures ("static part", somewhat comparable to paintings) with the code (making the textures interactive, animating them etc.). So I would come to the conclusion that the interactive part has been shared freely.
replax··on The Humble Bundle for Android (and Mac / Windows / Linux)
Yes I agree with you in regard to Bilzzard.

To be more precise, my questions is: You have an OpenGL based game running smoothly on OSX, you decide not to port it to Linux. Why?

1. ROI

2. "Have to" offer support for Linux to maintain brand image - very hard

3. hurts game image "game for geeks"

Obviously, it is hugely dependent on the piece of software you have.

replax··on Id Software Open Source releases on GitHub
Concerning your first statement, that the curation history is crippled: Obviously, you can get your hands on the artwork of the game if you want to, you just have to pay for it. Same as you have to pay for that picasso if you want to "curate" it. I don't see many people complaining that entry to a gallery should be free (although I would agree that it would be a very good thing and happened already in the UK) and that you are entitled a free copy of the artworks (by free I mean that you only have to cover the reproduction cost) to play around with.

So, please, you may get the full artwork for $2 on Amazon/Steam/Whereever.

replax··on The Humble Bundle for Android (and Mac / Windows / Linux)
You can use OpenGL & Qt for that matter. You can write proprietary software if you purchase a Qt license. In fact, programming with Qt is usually write once, compile for: Windows, OSX, Linux, Android. Most of the time, you will not need to adjust a single line of code for it to work. Given that you keep the other platforms in mind while designing your e.g. UI.
replax··on The Humble Bundle for Android (and Mac / Windows / Linux)
While I can understand not porting e.g. a DirectX game to Linux/OSX or any other program which heavily relies on OS specific libraries/features, I could not yet understand why not to port it when it is possible with little effort. I'd really like to hear an explanation from someone with knowledge in that matter, unfortunately the only example I can come up with at the moment from the top of my head is WoW/Warcraft/Starcraft. It runs on Win/OSX but has no Linux client. I do not understand why Blizzard would not release a Linux client for which no support will be available. A small team could probably achieve a port in reasonable time and create the update infrastructure around it.
replax··on Tesla Model S Options and Pricing
While I agree that e.g. the Xenon headlamps or the two USB ports should be standard instead of options, I know some people who would PAY to have to use the keys to lock/unlock their car. I experienced numerous occasions on which I was not able to lock my car because of interfering radio signals.
replax··on Everything You Thought You Knew About Learning Is Wrong
Yes, Anki used to use a slightly modified version of SM-5 but the Lead-developer decided to revert down to a modified and improved version of SM-2. Basically he reasons (you can find his explanation on the Anki FAQ) that while versions newer than SM-2 are supposed to (slightly) increase efficiency, it only happens if you study every day and at roughly the same time of day. The reason is, that starting with SM-3 a failure on a certain card changes the difficulty of (determined by the algo) similar cards. A further explanation by the lead developer can be found here: http://markmail.org/message/u2zfnrg7x53bzp24#query:+page:1+m... I am convinced that it (at least for me) offers much better studying conditions. (Actually, the mere fact that I can revise on a crowded 30min commute on my ipod would make up for any efficiency increase).
replax··on Everything You Thought You Knew About Learning Is Wrong
I also heavily use Anki for learning (Japanese). Although you can learn all sorts of things very efficiently with it once you get into the habit of using it. The program is great, it comes with >free< syncing/online backup, provides an iOS/Mac/Linux/Win/Android/Maemo client and a slick browser interface.
replax··on Everything You Thought You Knew About Learning Is Wrong
I have to agree with you, I generally find those link-bite "everything you blabla is wrong" titles rather offensive. It a) does not say anything about the content of the article, b) actually insults the reader in a blatant way and c) is a very cheap, offensive and apparently "hip" way of ruthlessly longing for click-throughs. I do not understand how titles like those keep getting up-votes and I feel quite sorry for authors writing good/ok articles and their bosses choosing horrible headings. I am sorry for the "off-topic" rant but it reached a tipping point for me.
replax··on Ninja Blocks: Connect your world with the web
Very nice concept! And by making them very very easy to use & pricing them accordingly high, they don't really compete with arduino+shields and the like. As they are "open", I wonder if it will be possible to only use their webservice with other devices (arduino etc) by paying a monthly fee.
replax··on Benefits of getting up early even if you don't want to code
I have been doing what the author describes for some time now (although I dont get up as early) and I find, that it works well to go to bed at any time on friday & saturday evenings as long as you give yourself enough time to sleep in as long as you want on the following day. On Sunday however, I will go to bed just as "early" as on e.g. Monday.
