You can certainly set reasonable limits. "After 512MB, start adding chunks of 64MB at a time." Similarly, you also really want a minimum bound so you aren't reallocating 12x to get to 4KB when you add a byte at a time (if you use realloc it may detect this, but not as easily as a min(4KB, size) in your allocation request.)

Plus at that object scale, you may want to start considering block pools for your data so you aren't copying all of that data by hand. It's very unlikely you have a >512MB object and also need to very frequently access all areas of it completely at random.

But as you said, it's always best to profile if you find yourself needing more performance.
I couldn't agree more with your comment. Maybe there is a way to collect data about user only after they have been anonymized, so the data would contain only what user_xxx does, with no way to map user_xxx to his real identity.

I don't think it's trivial, but I hope to see some regulations coming in the way the data are collected and stored.
Very interesting. Please do consider putting the extension up somewhere!

FWIW it was in UK, maybe in other countries the regulations are different, and probably they would have refused to change, say, my hard drive if there were a problem with it.

I dont have sympathy to how the finance sector has behaved historically, but this opinion can only come from ignorance.

This was a very good read.

My naive question are the gates are always so trivial or are they usually black boxes with an unknown function underneath(instead of clearly defined ,+, etc).

In other words do we usually/always know what stands behind f(x,y)?

Otherwise, if f(x,y)=xy then obviously you can hardcode a heuretic that just cranks up max x and max y and gets max f(x,y).

That is the question is why should we tweak the input slightly not go all out.

>The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and provide for the common defense and general welfare of the United States; but all duties, imposts and excises shall be uniform throughout the United States;

Article 1, Section 8 of the Constitution demonstrates Congress' authority to create an institution such as the NSA, whose main missions are (according to their website at least) Signal Intelligence and computer network protection. At least in the abstract, this isn't absurd

So much judicial precedent since the beginning of time has meant that people outside the US have less rights than those within it (I do not agree with this concept, but it is a core part of the judicial system as it is today).

Congress continuing to fund the NSA is the legal basis for their existence.

Mentioning slippery slope here is kind of funny since FISA is actually a counter-example! These things used to have no oversight at all! Now there is some minimal oversight (I stress minimal) from the judicial system.

The gov't is 3 separate bodies, each with their own way of viewing things. The judicial system has pushed back on the executive before on these issues, as has the legislative branch. Things are terrible but the system works, if barely.
Sure, but as a society we (should?) also try to discourage business models that significantly harm society without benefiting it in any comparable way. Hitmen provide a value to their customers in exchange for money, doesn't mean we need to allow it as a valid business model. Granted, that's a extreme example and with financial firms is often very hard to know which of their many business models provide a net benefit, a net neutral or a net harm to society. But the base premise of "well, companies should be allowed to act as unethically as the hell they wish" is not really a good or reasonable premise to accept.

The sf means "square foot", which is a weird way of pricing somewhere.

This flat in hackney is £675 per week and is 1700 square feet. (That's £2925 per month, or $4678 per month).

That price does not include council tax or utilities. Council tax at the lowest but full rate is £864.96 per month. That's roughly $1385 per month.
Bohmian mechanics has a very elegant way of dealing with identical particles. I know as I am a coauthor on such papers. The idea is that instead of R^3N with its labels, we use a space with no labels on particles. The only relevant data are the locations of the particles, not some extrinsic numbering. This immediately gives us bosons. Fermions take a little more work, essentially using a vector bundle approach analogous to Mobius strips. One can then prove that in 3 dimensions and for scalar wave functions, that is all the possibilities. For 2D, you also get anyons; this is all about the topology of the natural configuration space.

For spin, one has to realize that it is modeled well by wave functions that take on vectors as values. When moving to multiple particles with spin, we tensor (kind of multiply) those vectors together. But the key point is that we tensor based on the spatial location. So instead of tensoring over particle 1 and particle 2, we tensor over their positions. This gives us complicated vector bundles. It opens a lot more possibilities, but when you look at general quantum dynamics, the only stable ones in 3D are the bosons and fermions.

Thus, not only can Bohmian mechanics account for it, it actually provides a very natural explanation. It is completely rooted in considering what the configuration space is. Where Bohmian mechanics shines is that what the configuration space is comes from what the theory itself is concerned with, namely particles with definite positions.

And just as a side note, the standard formalism of quantum mechanics emerges in a mathematically rigorous way from Bohmian mechanics. Everything in non-relativistic quantum mechanics is completely accounted for and you get a clear foundation for extending it to other spaces and more general questions.

As for relativity and quantum field theory, that is still a work in progress, but the main stumbling block is actually having a well-defined evolution of the wave function in interacting cases. If we had that, then the Bohmian additions are easily handled for the most part. Research has been done and is being done.

A simple (layperson) reference for this is sadly lacking, but you can try either http://arxiv.org/pdf/quant-ph/0506173.pdf or my thesis (chapter 5) at http://jostylr.com/thesis.pdf Hopefully they are somewhat accessible to this audience.

Reinventing control structures in an expression language and placing that in HTML attributes should tell you everything you need to know about AngularJS foolishness. Why should users incur the penalty of download something some needless as an express ssion language when JavaScript is already richly expressive? Why cause developer anguish by having an expression language which can not be statically checked and throws silly stacktraces? It makes zero sense.

The only thing you need is the last mile transformation from view model to DOM, everything else that AngularJS provides is unnecessary and foolish.
About identical particles, see my other comment at https://news.ycombinator.com/item?id=8556052

But the main point of why Bohmian mechanics over standard quantum mechanics is that the standard one is ill-defined. "Collapse happens when a measurement occurs, but not before." What is a measurement? Trying to make this precise is a problem. Collapse too early and you get the wrong results while collapse too late and you get into the cat paradox. Bohr, I believe, understood this which is why he advocated for a split between classical and quantum with a statement not to worry about the split.

There are other ways of dealing with this problem, but Bohmian mechanics is the simplest in my opinion. Instead of something that is sometimes wave-like and sometimes particle-like, we have two things: a wave and a set of particles. The evolution of the particles is governed by the wave. Everything in standard quantum mechanics can be deduced by this picture.

Enabling authors to self publishing is something we're doing with GitBook (https://www.gitbook.io/).

We have a one source format based on markdown which is open source (https://github.com/GitbookIO/gitbook) ! And from this we build a nice web book, ebook (EPUB, MOBI) and PDFs.

I don't want this to be a shameless plug, it just seems oddly relevant. Hope it helps !

Only if the attacker had no part in making the "safe" ISO image in the first place. You just cannot know. Using MD5 makes no sense whatsoever, if you don't need collision resistance, there are faster options, and if you do, it's obviously completely unsuitable.
De Broglie–Bohm theory does not have local hidden variables, it has global hidden variables. The difference is quite fundamental. Paper falling is influenced by local hidden variables, because all interactions are described by Euler-Lagrange equations which being differential equations are by their very nature local.

Global hidden variables are no different than modelling quantum mechanics on a computer (using traditional quantum field theory) and saying that the seed you use for your random number generator value is a global hidden variable. There's nothing deep in that.
"Up" does still bring a unique viewpoint.

Waiting for space-stations/moon-bases/whatever before working on cheaper ways to get people there leads to a massive chicken-and-egg problem. We do have a reasonable idea of how to build space stations, once the demand is there.

The trouble with many worlds, for me at any rate, is say you have a mirror where the photons go one way 94% of the time, the other 6% of the time. How does that work? 94 worlds of one type and 6 of the other? Everett did some hand wavy, we assign a probability P to each outcome stuff but you still wonder how on earth that works physically. If the universe branches with one version of you seeing it go one way and one the other is one of you more existy or what?

This is similar to what I wrote at work on and off over the last couple of months, replacing a build system using recursive Makefiles. Due to the way our product is composed I ended up adding support for building static libraries, programs, RPMs and documentation. With full support for dependencies, meaning if a source for a library is changed, the library will be rebuilt, programs that links against it will be re-linked, if the program is part of a RPM it will be rebuilt etc. Documentation will also be rebuilt if source embeds documentation. Another great bonus is of course that with one GNU Make instance and proper modeling of dependencies "make -j" works great, every time. I guess we have a couple of hundred source source files and "make -j" will happily start compiling them all. Read Peter Millers paper about recursive Makefiles about why the above is preferred.

Makefiles are of course a bit limited compared to shell scripts, but you can do a lot with implicit rules, static pattern rules, second expansion, call and eval, etc.

Bridgepoint invests $30M in Trustly (company behind BankAPI)
I have no problem with that statement unless you are working for a venture backed company yourself. The origin of a lot of growth in the valley is due to finance companies funneling money from pension funds and other institutional investors into VC firms. If it wasn't for the FED printing money like crazy and institutional investors scrambling to get any return on their assets Silicon Valley wouldn't have grown nearly as much in the past (and would also have had fewer bubbles).

Then again, the typical high-performance sedan doesn't have much range either at 250km/h. At that speed, a 3-series will burn through 30L/100km and they have a 60L tank. A 5-series has a 70L tank but I don't know how much fuel it goes through at 250. I don't expect significantly better efficiency though.

I search for 'Balls' and got many hits, most irrelevant and uninteresting.

Then I searched for the exact title of your app and got about 13k hits. None of the first 100 which was your app. I downloaded it through iTunes eventually.

That makes me wonder: how do you promote (iOS) app discovery? There are plenty of analytics startups for this, but is anyone trying to improve this process?

edit: Searched around for curated app websites / stores. There are some, but lack in depth and quality. I'm starting my own.

One question - What aether/field do the pilot waves travel in? E? B? something else?
You're absolutely right, and too few realise this.

In particular people doing IO with small buffers drives me crazy. People unfortunately don't seem to realise how expensive context switches are, and how brutal they are on throughput.

I've seen this so many places. MySQL's client library used to be full of 4-byte reads (reading a length field, and then doing a usually-larger-but-still small read of the following data). I believe it's fixed, but I don't know when. I also remember with horror how t1lib - a reference library Adobe released for reading type 1 fonts ages ago (90's) that spent 90%+ of it's time on the combination of malloc(4) and read( ... ,4) - for tables of a size known at the outset (basically some small table with one entry per glyph, that stored a pointer to a 4 byte struct instead of storing it inline).

Currently I'm hacking on SDL_vnc now and again, and it's full of 1-16 byte reads (seems to make sense at first glance: After all the VNC protocol packets are of a size that depends on values of different fields; but for high throughput networks or local connections it makes the small read/writes totally dominate overall throughput even when the protocol overhead is a tiny percentage of the bitmap data being pushed)

Basically pretty much anywhere where you want to read less than 4K-16K, possibly more these days, it's better to do buffering in your app and do non-blocking read's,so you can read as large blocks as possible at the time...

But the general problem is not paying attention to the number of system calls. People not paying attention to stat()/fstat()/lstat() etc. is another common one (common culprit: Apache - if you use the typical default options for a directory, Apache is forced to stat its way up the directory tree; it's easy to fix, but most people don't seem to be aware how much it affects performance)
