+Minori MATSUDA  "Konstapel" can mean both "police officer" and "stack of cones".

It's a very stupid joke. :)

Online Bonsai beginner's course. Looks interesting.
 
OSAKA - The Bonsai Beginner's Course demystifies the ancient art of Bonsai, finally making this fascinating hobby accessible to a wide audience. With over a thousand early birds signed up last week, the course is already a great success.

In the online course we introduce the historical and cultural backgrounds of Bonsai, but our focus is on explaining the most important techniques step-by-step. Everything we do is practically oriented; we assist students in growing and styling their very own Bonsai tree. Anyone can enroll and start their journey into Bonsai art, coming June 1st!

Thanks!
Bjorn Bjorholm and Oscar Jonker


Last early bird tickets (-20%) are still available at:

I'm looking for another word for "high-throughput computing" (as opposed to high-performance computing). "Grid computing" describes the typical architecture you use for it; and "loosely-coupled" describes the kind of problems it's well-suited for.

I'm sure there is a better word, and I just can't remember it. Any ideas?

SD cards can speak SPI natively. I never realized that. That should make large-scale data storage immensely easier for small embedded projects.

Here's a quick example that shows how to add an SD card header to an Arduino (all you need ar ea few resistors): http://www.martin-gardner.co.uk/how-to-connect-your-old-sd-card-to-an-arduino/
And the example code is in the IDE already: http://www.arduino.cc/en/Tutorial/ReadWrite

Here's an alternative library for Arduino that looks like good example code to look at: https://github.com/jbeynon/sdfatlib
And a tutorial using it: http://garagelab.com/profiles/blogs/tutorial-how-to-use-sd-card-with-arduino
The Secure Digital Memory Card (SDC below) is the de facto standard memory card for mobile equipments. The SDC was developped as upper-compatible to Multi Media Card (MMC below). SDC compleant equipments can also use MMCs in most case. There are also reduced size versions, such as RS-MMC, ...

I have to agree with +Jan Moren
I don't see I2C and SPI as competitors, as much as complimentary options that both have usage scenarios where they are the better choice. Sometimes a project will best work when using both protocols for different functions.

Time for a little rant:

Research is not a calling, and a Ph.D. is not an ordination. Science may be your passion, but scientist is a job. Your first duties are towards your family and yourself, not towards your work. You have no obligation to sacrifice all your time, your health or your family for the sake of Science, or Knowledge, or Progress.

Perhaps you'd do science in some form no matter what; I know I would. But you are writing papers, pushing grant applications, attending meetings and all the rest because it puts food on the table and a roof over your head.

Science is a job. A good, fun, rewarding job, but a job. Remember that whenever somebody tries to convince you otherwise.

This is just the outcome of an overall narrative  in my mind, that narrative being the dominance of competition and capitalism.  
How do you get more work out of people without specifically assigning them more work (because that's a labor issue)?  You shame them into thinking it's their "duty" to do so because of their "passion" for their profession.  Professionals and academics, because of the way salary is paid, the lack of regulation laws pertaining to salary, and the theoretically endless amount of time someone can spend working on problems that professionals typically tackle, are the new slave labor force.  They're just better paid on average and bound by guilt and societal conditioning, rather than oppression.

I just declined a paper review. It seemed a nice enough paper, it was sort of in my (previous) field, and I know reviewers can be hard to find. But I realized I don't know enough about the main subject of the paper to actually write a good review, or make a well-informed decision on acceptance.

A bad reviewer is worse than none, so I declined. Still, it feels like I'm shirking a duty.

This post/essay/code example about recurrent neural networks has done the rounds lately. it highlights the extremely impressive results that current neural net methods can achieve, but also their limitations.

The code example is particularly instructive. After training on the Linux kernel source, it can generate mostly syntactically correct code based on whatever input you give it. That includes not just using keywords in the right places, but things such as matching parenthesis (and knowing what can appear within), and keeping correct code indentation. It can learn larger, context-dependent structure, not just the surface-level pattern sequences. The network implicitly represents the syntax of the input, and that's very impressive.

On the other hand, the code sequences have no meaning. They don't try to compute anything; they just are. Some of them may compile, but none of them do anything meaningful. It has extracted syntax, but fails to produce anything semantically meaningful.

You see the same thing with the recent examples of deep learning network learning to play games: they learn the syntactic structure of the in-game tasks, but the playing is not goal-directed; there is no concept of "winning", or of achieving anything by playing.

Now, I don't think those are insurmountable obstacles. Semantics and pragmatics, or motivation and autonomy is not magical pixie dust. But it does require a lot more structure than a fairly task-constrained training of a single network can achieve.

There's a reason brains are very highly structured systems, with lots of separate subsystems interacting in well-defined, highly constrained ways. Even a pre-term developing brain is anything but a blank learning slate, and smaller, simpler brains (insects, say) are if anything much more highly structured than larger ones.

Also, deep learning networks are paradoxically also too general. They can learn any well-defined temporal structure, but they are computationally very inefficient at implementing and executing any one structure in particular. I suspect that in many applications, creating networks like this will be only an intermediate step; a way to constrain and understand the problem before you implement it "for real", in a much more efficient manner.

Take an artificial leg as an example. It is only syntax: a time-varying, context-dependent input (nerve signals, sensor info) gets translated into a time-varying output (joint movement). But implement that directly in an neural network and the user would need a separate backpack with the computer to run it in real time. Instead you need to extract the functions the neural network has implicitly learned, and implement them, in a far more efficient manner, in something similar to a regular old-fashioned control loop.

Current neural networks are both far more capable, and far more limited, than many people realize. I suspect future work will need to focus more on the large-scale structure, and less on adding more nodes in the network or finding still-larger training sets. Fun times ahead.

You probably could, though you'd have to feed it complete code examples so it sees that declarations are always necessary.

On the other hand, programming languages is one instance where we really do have the formal syntax in hand. I bet we could get even better results than this, faster, by using a generative parser and training a Markov chain model on the transformed input.

Learn to program the C64 in short screencasts! This would have been worth it's weight in gold when I was about 15(1). It's amazing that programming that machine is still an actual thing. It's probably the most fun I ever had, before or after, so it's perhaps not that strange.

1. Of course, as a 15-year old I wouldn't have had that gold so we would probably just have pirated it, just like we did with everything else...

I have to say that about Osaka mayor Hashimoto: he may be right about things or he may be wrong, but he does honestly care about Osaka, not just his own career. That's not something you could say about many of his predecessors.

In short: coffee is almost uniformly very good for you, with no negative health effects. But this goes only for black coffee, in moderate amounts, not for the coffee-flavoured milk-and-sugar soft drinks that coffee chains also sell.
A review of studies shows that coffee’s reputation as being unhealthy is undeserved, with the potential health benefits surprisingly large.

Janne. In Osaka.
Introduction
From Sweden, but I've been living in Osaka for nine years. I've worked in cognitive science, neuroscience and robotics.

I am affiliated with Okinawa Institute of Science and Technology, but placed at the RIKEN Advanced Institute of Computing Science in Kobe, where I work on a project to model the subcortical motor-related areas in order to better understand the physiological effects of Parkinsons disease.

My favourite omuraisu restaurant. The place is in a slightly seedy part of Namba, south of Amemura on the "wrong" side of Midosuji avenue, but the restaurant itself has a very calm, pleasant and slightly old-fashioned vibe that feels more high-class than you'd expect from an omuraisu place. Plenty of tourists; on one hand you won't feel out of place as a visitor (and there's English menus available too), but on the other, you are as likely to rub shoulders with a fellow tourist as with a local. Some people dislike it, others are comforted by it of course. The omuraisu itself is very, very good. I've had several varieties and they've all been tasty. I especially like the mushroom-sauce variants. Plenty of food, but there's set meals and a fair assortment of side dishes to pick from as well if you want (fried shrimp always goes well).

Pleasant ramen place with traditional decor but a modern take on the food. The soup is very thick with more than a hint of sweetness. The noodles are pleasantly chewy. Japanese-style toilet.
