13. Interview: Freaklabs’ Chris “Akiba” Wang

John Baichtal Maker Media, Inc ePub

John Baichtal

Akiba talks about moving out of the Tokyo HackerSpace and into the Hackerfarm.

John Baichtal: You were at Tokyo HackerSpace, and then…how long were you there? Are you still a member?

Chris Wang: Nah, not really. I can’t make it out there. I live an hour and a half outside of Tokyo now. It was me and another founder of Tokyo HackerSpace, and then a rice farmer. He also was in Tokyo HackerSpace in the beginning, too. The three of us got together and started a farm, actually. My friend was a rice farmer out here. At that time, I was into cheesemaking. I was like, “Well, OK. It’d be nice to have access to raw milk or cheese.”

At first, it started kind of innocuously and he’s like, “The rent’s cheap out in the countryside.” So I was like, “Oh, well how cheap?” So right now, I’m renting three buildings and the rent is like $400 a month. Three buildings and then you’re basically gifted farmland. It’s like, “Here, here. If you can work it, just work it.”

9. Drug abuse and inanimate objects

David Rosenfeld Karnac Books ePub

In this chapter I describe the psychoanalytic study of the psychopathological changes that can be detected in the treatment of drug addicts, based on the clinical evolution of several such patients. In this evolution, I have found a number of characteristics that, in my experience, can be generalized. I attempt, then, to show the evolutional steps detectable in the course of the clinical treatment of these patients, the approach being similar to that previously used in my study of successive stages in a therapeutic group (D. Rosenfeld, 1988). I also advance new concepts explained on the basis of the theory of the primitive psychotic body image (p. 235), as well as the idea that addicts are in a continuous search for primitive autistic sensations (p. 256), and I develop new ideas related to life, death, and suicide in addicted patients (p. 247). I also propose a new classification of three different types of these patients.

The management of the patient who is addicted to drugs is particularly difficult because the analyst is dealing not only with a specific set of symptoms, but also at the same time with the combination of a mental state and the intoxication and confusion derived from drug use. In view of the length, difficulties, and vicissitudes of the treatment of drug addicts, I found it important to be able to establish milestones in order to find my way along the evolutionary course of transference neurosis and psychosis, which is of basic importance in the treatment of these cases. ‘The understanding of the specific psychopathology of drug addiction must result from the study of the transference neurosis and psychosis, always within the psychoanalytic setting’ (Bleger, 1967).

3. Dissecting Web 2.0 Examples

James Governor Adobe Developer Library ePub

Web 1.0 was about connecting computers and making technology more efficient for computers. Web 2.0 is about connecting people and making technology efficient for people.

So, what actually changed between the emergence of Web 1.0 and Web 2.0? In this chapter, well compare Web 1.0 companies and technologies with Web 2.0 companies and technologies to begin developing the design patterns that distinguish them. We use the term Web 1.0 to refer to the Web as it was understood in the period of around 19952000, though obviously its not a simple matter of dates. To help us get started, Figure3-1 shows again the list of Web 1.0 and Web 2.0 examples that Tim OReilly and others compiled during an initial brainstorming session to get a feel for what Web 2.0 was.

Figure3-1.Tims list of Web 1.0 versus Web 2.0 examples

Its important to note that some of the Web 1.0 companies included in Figure3-1 have evolved substantially since Tim made his original comparison. For the latest information, definitely visit each companys website. Tims choosing them as examples actually speaks to their success in that earlier age.

5. ASPError Object

Keyton Weissinger O'Reilly Media ePub

Introduced with ASP 3.0, the built-in ASPError object allows you to view detailed information about the last error that occurred in the script of an ASP page in the current session. This object, through its nine read-only properties, provides more detailed information about the type and source of errors than does the Err object provided in VBScript.

To use the ASPError object and its properties, you must call a new method of the Server object, GetLastError, which returns an ASPErrorObject with its properties' values set to reflect details about the last error that occurred in the script:

When you install IIS 5.0, by default, all preprocessing, script and runtime errors in ASP code cause IIS to stop processing the current script and redirect script execution to a custom error page named 500-100.ASP. This redirection occurs through an internal call to the Server.Transfer method which, as detailed in Chapter 9, shifts execution from one script to another while protecting all state information available in the first script.

Performance Model for the Impact of Hardware Characteristics in

Accelerated Processing Units

Abstract— The importance of Graphic Processing Units

(GPU) as high performance accelerators has been increasing since the late 90’s. However, a limiting factor of the peak performance that a GPU can achieve lies in the bandwidth limitations of the interface used to connect the GPU to the rest of the system. The Accelerated Processing Unit (APU) was developed as an attempt to deal with this limiting factor.

Aiming to provide insights of the behavior of memory-bound kernels in APU systems, we develop a performance model for the Matrix-Matrix Multiplication (MMM) algorithm as it is executed in the APU. The model is elaborated from the analysis of a tiling MMM kernel. By studying the different aspects of the execution in the APU hardware and utilizing a statistical approach we developed a model to estimate the impact of hardware characteristics in the performance and attempt to explain the nature of the experimental results. The formula consist of a linear combination of three terms, global memory accesses, local memory accesses and floating-point operations times. These three factors are integrated into a performance model formula by applying the
