KASEY CHAMBERS LYRICS - Freight Train: "Well every time I fell behind
And I could not get ahead
I wish someone would pull the lever
And give me a little sand
And every time I slip behind
Even further back
I wish some switchman would come out of the fog
And change my track
Wish I was a freight train baby
Wish I was a diesel locomotive
I'd come whistlin' down your track
Crashin' in your door
Wish I was a freight train baby
Wish I didn't have a heart
And you'd need a shovel for the coal
Just to get me started
Wish I was a freight train baby
Wish I was a freight train . . ."

Pigs, Bees, and Elephants: A Comparison of Eight MapReduce Languages « Dataspora
Pigs, Bees, and Elephants: A Comparison of Eight MapReduce Languages « Dataspora: "I will present for each language or library the implementation of a word count program, lifted from its documentation, since this has become sort of the “Hello World” for map reduce. I don’t think such a simple program is the ultimate test of the quality of a language, so this is just to give a taste of the language. What I am most interested in is:
Can I write reasonably concise, abstract programs in this language or library?
Can I write the “inside” of map reduce, that is the code for the mapper and the reducer, as well as the “outside”, the logic that decides which map reduce jobs to run?
Is it general? Can I write any map-reduce program, including programs that require multiple map-reduce jobs, including the case of a data dependent number and type of jobs?"

Top 5 exceptions in Google App Engine - Sfalma Blog
Top 5 exceptions in Google App Engine - Sfalma Blog: "1. Routing Exceptions
The most common exception is the routing exception. Usually a resource is missing (like /favicon.png - the most common file missing).
2. Timeouts
One of the biggest headaches in GAE is timeouts (usually due to database queries or urlfetch). Either the service you are trying to connect is taking too much time to respond or you have a very complex/slow query. You can solve it by using AppStats (you are using AppStats right?) or putting retries (usually around 3 - you don’t want to drain your resources on something that is not working).
3. UnicodeDecodeError
“ascii codec can’t encode characters in position 56-62: ordinal not in range(128)”
Everyone hates those nasty strings. encode, decode, utf-8, ascii - come on! please work! Pro-tip: always bet on utf-8.
4. Method Not Allowed
You have a route that waits for POST but you are doing a GET (vice-versa is not so common).
5. AttibuteError - NoneType
AttributeError: ‘NoneType’ object has no attribute ‘lat’
You expected that some object existed and you tried to access an attribute right? Admit it! Always check if a query returned any results.
6 (bonus). Your errors
Values, DivideByZero and many more."

Skilldrick » Magic in software development
Skilldrick » Magic in software development: "What we need to get to, eventually, is an understanding of the whole stack, but at greater and greater granularities as we get further away from our main level. So, if you’re a Ruby on Rails programmer, you need to know most of Ruby (but not all of it). It’s helpful to know a bit of C, and a bit of how the operating system responds to certain commands. Below that level, it’s good to have a vague understanding of how a computer works. And it’s useful to know that electrical signals can only transmit at a finite speed, and that there’s a physical limit to the number of transistors in a processor. As time goes on you can begin to flesh out these lower levels, remembring that the higher levels are generally going to be more beneficial to your day-to-day work."

All of the A5s headed north through Weynton and into Cormorant Channel towards Sointula before they made a turn back towards Mitchell Bay. At that point they began traveling very close to shore towards Donegal Head where they continued heading west. Thanks to Jared Towers of DFO for the update! Looks like we missed seeing them, but it was wonderful to hear them!

When faced with an absurd and unexpected situation - the gradual disappearance of first the crew and then the entire universe - she at least considers that she's the crazy one."

And this is the meat of the matter. Let’s look at a simplified version of the above example first:
It’s no surprise that when you call f with the argument 5, when g is called it has access to that argument. What’s a bit more surprising is that if you return g from the argument, the returned function still has access to the argument 5 (as shown in the original example). The bit that can be a bit mind-blowing (and I think generally the reason that people have such trouble understanding closures) is that the returned g actually is remembering the variable x that was defined when f was called."

The myth of the Lisp genius — The Endeavour
The myth of the Lisp genius — The Endeavour: "Another possibility is that super-programmers are attracted to Lisp. That’s the position taken in The Bipolar Lisp Programmer. In that case, lesser programmers turning to Lisp in hopes of becoming super productive may be engaging in a bit of cargo cult thinking.
I find the latter more plausible, that exceptional programmers are often attracted to Lisp. It may be that Lisp helps very talented programmers accomplish more. Lisp imposes almost no structure, and that could be attractive to highly creative people. More typical programmers might benefit from languages that provide more structure."

A Camera Ravenous for the Humpback Close-Up - NYTimes.com: "Looking into the whale’s eye, lit by sunlight through the water, Austin felt he was getting a glimpse of calmness and intelligence, of the animal’s consciousness. The moment changed Mr. Austin’s life. It struck him that something was missing from four decades of whale photography: the beauty of true scale. Mr. Austin concluded that the only way to capture the magnificence of whales would be to create life-size pictures of them. “I wanted to recreate the feeling I had when I looked into the eye of the mother whale,” he said."

Marie was out in the boat on her way to Alert Bay when the transients went by at 11am. She was able to have a brief look, long enough to ID them as the T23s. Making another Blackney Pass go through. The sea lions didn't seem to notice. The whales kept going into Johnstone Strait. Thanks Marie - have a great time in town!

How to Lay in a Hammock - Hammock Laying TIPS & ADVICE from 'The Hammock Shack' courtesy of Westmount Living
How to Lay in a Hammock - Hammock Laying TIPS & ADVICE from 'The Hammock Shack' courtesy of Westmount Living: "Where as Spreader Bar hammocks encourages one to lay straight as the fabric is spread evenly and taut due to the integrated spreader bars. A correctly hung classic hammock (non-spreader bar) allows for a diagonal lying position, like a real Brazilian ('from corner to corner'), not straight. This keeps the back straight and is the secret of being able to lie comfortably and relaxed for hours on end in a hammock. Though one can lie in a hammock lengthwise or across its width, most hammocks are best used with a diagonal position, as it provides the most room and support. Users with back and joint pains often report some relief from these problems when sleeping in a hammock in this manner."
The Hammock Angle: How To Relax And Sleep Comfortably In A Hammock, Even If You’re A Side Sleeper
The Hammock Angle: How To Relax And Sleep Comfortably In A Hammock, Even If You’re A Side Sleeper: "Begin by lying in the hammock directly down the center as you normally would. Now, take your feet and legs and move them about 8-12 inches to one side. Do it until you notice that they are suddenly sitting much lower and flatter than they were. Now, do the exact same thing with your head and the upper part of your body, except towards the opposite side.� If you did it correctly, you’re now lying almost completely flat in a curved hammock."

TouchStudio - Microsoft Research: "TouchStudio is a new programming environment and language built around this new reality. Its typed, structured programming language is built around the idea of only using a touchscreen as the input device to author code. It has built-in primitives which make it easy to access the rich sensor data available on a mobile device. In our vision, the state of the program is automatically distributed between mobile clients and the cloud, with automatic synchronization of data and execution between clients and cloud, liberating the programmer from worrying (or even having to know) about the details."

JavaScript: Don't reassign your function arguments | Atomic Object, Software Design & Development
JavaScript: Don't reassign your function arguments | Atomic Object, Software Design & Development: "The numbered properties of the Arguments Object are synonymous with the local variables that hold the named function parameters. They both reference the same address in the stack. If the function body has code that changes the value of a parameter either via a name reference or the arguments[] array reference, both referenced values will reflect the same value."
Accurate geolocation using IP address
Accurate geolocation using IP address: "To use the method you first need some servers that you know the location of. Wang used Google Map servers. Next a rough fix of the location of the target machine is performed in the usual way i.e by measuring packet transit time from a number of 'ping servers' spread out at known locations. You can determine where the target is located using triangulation from the transit time of the packets from each of the 'ping servers'. This gives a location fix that is generally accurate to around 200km. The clever part of the algorithm is that with this rough fix you can determine which of the known machines are close to the target machine. You can then use a trace route to compare the routers that the known machines have in common with the target machine. Then, using transit times, the distance from a known server can be refined."

Unexpected Speculative Stability » #AltDevBlogADay
Unexpected Speculative Stability » #AltDevBlogADay: "The chief reason for the unexpected stability with speculative contacts, is that it solves one of the principle problems with discrete collision detection; contact flip/flop. This is when a contact is detected and then resolved repeatedly over the course of many frames. The discrete collision detection and resolution system will detect a contact (typically with distance < kThresh type comparison), resolve it and then after a few frames it will get pushed out of contact again and will fall very slightly towards the ground and get re-detected. This repeated pushing out/re-detection cycle will cause instability and jittering in the system."

Sample Workflows — Kepler
Sample Workflows — Kepler: "The Web Services workflow uses Kepler's Web Service actor to invoke a genomics data web service, which accesses and queries a remote genomics database and returns a genetic sequence. The name of the sequence (i.e., the gene accession number) is passed to the Web Services actor by a String Constant actor.
After the service has executed, the Web Service actor outputs the retrieved gene sequence so that it can be displayed in multiple formats using three different Display actors: one for XML (the format in which the results are returned by default), one for a sequence of elements extracted from the XML, and one for an HTML document that can be displayed on a website. In addition, the workflow uses a fourth Display actor to display errors returned by the remote server (e.g., server down or incorrect input)."

KFlex — Kepler
KFlex — Kepler: "KFlex (Kepler Flex) is an extended version of Kepler with an Adobe Flex 3 client developed at the German Research Center for Artificial Intelligence (DFKI).
KFlex consists of two components:
KFlex Server: An extended version of the Kepler 1.0.0 release with WebService interface for workflows and packaged as Wep Application
KFlex Client: An Adobe Flex 3 prototypical implementation of a Kepler client to edit and execute Kepler workflows (see snapshot below)"

working memo: Kepler: "The first impression of Kepler is good, not only for it was born from UC Berkeley, but also for the rich collection of built-in tools. Unlike Taverna and LONI which aim to help bioinformaticians, Kepler was designed for a broaden range of disciplines."
12.5. Introducing WSDL
12.5. Introducing WSDL: "A WSDL file is just that: a file. More specifically, it's an XML file. It usually lives on the same server you use to access the SOAP web services it describes, although there's nothing special about it. Later in this chapter, we'll download the WSDL file for the Google API and use it locally. That doesn't mean we're calling Google locally; the WSDL file still describes the remote functions sitting on Google's server."

Re: Matplotlib - an odd problem: "Your code redraws over the same graph over and over again. You need to
create a new graph each time you want to draw something new. It took me
ages (and help) to figure out how the non-global APIs in matplotlib.

matplotlib without a GUI: "matplotlib has two primary APIs. The easiest to use is the pylab interface. When that module is imported it checks for a setup file, initializes the GUI, and does a few other things to simplify interactive plotting. pylab is built on top of the matplotlib API. This is a more object oriented API, but still not that difficult to use. They can be used together, as you might have seen in my code from last time."

jtnimoy - Tron Legacy (2010)
jtnimoy - Tron Legacy (2010): "After this project, I was fed up enough with wxWidgets and Carbon that I was ready to author my own OpenGL based UI. The most important thing I could use is a floating-point slider. I also got irritated with the way the Carbon sliders would not slide all the way to the minimum and maximum values. It totally messed with my zen thing. Also, after a job like this, it's clear that a member of the Processing community working within a CG community is greatly restricted by the differences of realtime graphics rendering engines, and that probably messes with an art director's zen thing."
jtnimoy - Tron Legacy (2010)
jtnimoy - Tron Legacy (2010): "When fixing Quorra, there was an element in the DNA interface called the Quorra Heart which looked like a lava lamp. I generated an isosurface from a perlin-noise volume, using the marching cubes function found in the Geometric Tools WildMagic API, a truly wonderful lib for coding biodigital jazz, among other jazzes. The isosurface was then drawn along different axes, including concentric spheres. The app was mesmerizing to stare at."

matplotlib without a GUI
matplotlib without a GUI: "To make the image file using the matplotlib API I need to make my own Figure and FigureCanvas. I'll use the FigureCanvaseAgg for the last. The from pylab import * brought in some numeric functions and the Polygon class automatically, so I'll need to import them myself"
