Sometimes R code just isn't fast enough - you've used profiling to find the bottleneck, but there's simply no way to make the code any faster.... You'll learn how to rewrite key functions in C++ to get much better performance, while not taking too much longer to write. The key to this magic is Rcpp, a fantastic tool... that makes it dead simple to connect C++ to R. If this is too easy, you can always use C or Fortran.

Naming things is hard. Why do we expend so much effort to get them right? Because naming programming concepts well gives us a big insight into how they fit into the system we’re designing. Continually renaming things records our insights as we go: the right names for our objects, methods and variables will yield fresh insight and in turn shape the design of the system. A variable by any other name would... probably be the wrong type, too.

Most programmers start off their career relatively idealistic, and often marvel at the power of little used programming languages. For me, this language was Common Lisp, which I got to work with professionally. At first I believed that Lisp still had the power to revolutionize programming, but after a few years of work I realized exactly why Lisp ended up in the position it is now: community. Every programming community has a few core beliefs, both explicit and implicit, that shape the language, the libraries, and its users. The Haskell community believes that errors should be caught by the compiler as often as possible, and Ruby believes in the principle of least astonishment. The Lisp community suffers from a belief that I call the Myth of the Lone Hacker. This code ain't big enough for the both of us...

Fortunately, the blog was short so I don't feel like I wasted too much time on it.

It’s incredibly exciting to see how the Web is evolving, and 2013 has a lot more in store. Over the next year, there are a number of technologies coming down the pipeline that have the potential to radically transform how we use and develop for the Web.... While many of these APIs will take some time to filter over to other browsers, the market share that WebKit wields will pressure other browser vendors to offer their own implementations. Coming soon to a browser near you.

It’s hard to believe it’s been just over a month since Surface with Windows RT hit the market. The response from Surface customers has been fantastic and exciting to see.... Today, I want to share a bit more detail about the growing Surface family of products and Surface with Windows 8 Pro, specifically around pricing. In January, Surface with Windows 8 Pro will be available in two versions and pricing will start at... 64GB standalone version at $899, 128GB standalone version at $999.

A group of developers hoping to turn Open webOS into an Android app recently claimed it is getting closer to achieving its goal. Phoenix International Communications, made up of volunteer hackers, recently posted a video to YouTube showing a “pre-alpha” version of webOS running on a Samsung Nexus S 4G. Stable, but slow and useless... just like the original webOS.

Way back in August, three months before the release of Windows 8, we learnt about the existence of a project at Microsoft codenamed Blue. At the time it wasn’t clear whether this was Windows 9, or some kind of interim update/service pack for Windows 8. Now, if unnamed sources are to be believed, Windows Blue is both of those things: a major update to Windows 8, and also the beginning of a major shift that will result in a major release of Windows every 12 months — just like Apple’s OS X. In other words, Windows Update becomes Windows Upgrade.

I predict this is going to go over like a lead balloon with 99% of enterprises; while most of the remainders pointyhairs will see this as a way to get fondleslabs (kinda vaguely sorta like) their serfs are demanding while making sure that they can't install any unapproved applications by keeping the corporate standard at least on release behind MS's current standard.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

My thinking: Microsoft's bread and butter is enterprise SA contracts, and they expect the majority of SA licensees are either still upgrading to Win7 or planning to stick with it for a while. Then you can think of Blue as a series of Win8 service packs.
When the "Blue" platform picture looks solid enough and the time is right, enterprises will upgrade. Or not... as is already the case with shops still using XP because, well, it works.
OTOH, most consumers just get whatever ships with the hardware they buy, so this doesn't matter that much.
And finally, this could all be BS strategy talk that will never be implemented.

Coming to a month near you; the Surface Pro launch will be in January[^]. The 64GB version is $899 and the 128GB version is $999.

It will apparently only have 4GB of RAM. Pity, I might have considered one if it had 16GB.

I'm currently using it on an Ultrabook with 4GB and it runs perfectly well.

I guess it's a bit silly to expect to be able to do SharePoint development on a tablet.

I'm doing WPF development on this and it's fine.

SharePoint Server 2013 has a minimum requirement of 24GB for development, though it works fine (so far) in a 12GB virtual machine on my Mac with 16GB of RAM. I've heard of serious issues encountered at 8GB and less.
RAM isn't even that expensive these days. On NewEgg, you can get 16GB for around $75. I'm sure the cost changes for smaller form factors like tablets, but it looks like I won't even be given the option of paying more for more RAM.
Oh well, like I said, it's silly to expect to do serious development on a tablet. Maybe it'll be more feasible in a couple years.

As I said, I'm fine doing WPF development on this, so I reckon it should be OK on the Surface Pro as well. I'll even do some Windows Store stuff on there as well.
I looked at SharePoint a while back and decided it wasn't for me.

Just remote to your machine with 12GB of ram from your tablet. Best of both worlds... or a compromise of both worlds.

Then how do you access your long term memory? Or google as the kids these days call it

There are, on occassion, entire moments in which I don't use Google.
