How I Got a New MacBook Pro for $325

How I Got a New MacBook Pro for $325

Well, let’s start off by getting this straight – it was NOT a brand new MBP, but it sure does feel like it is.

I have a 2010, almost top of the line MBP – 15”, 2.66 GHz Intel Core i7, NVIDIA GeForce GT 330M 512 MB, and the matte display. I bought near the top because I do a lot of serious photography (have had a few exhibitions) and a little bit of video, and I need the processing power to do this. (You can see some of my work here, and event photos here.) I have since maxed the memory out to 8 GB.

The Problem

The system ran like a dream and I have been very happy with it, (Actually, the graphics card had problems stemming from the Nvidia processor, but Apple replaced it for free – twice!)

Everything was fine as I upgraded with every new OS X release. Snow Leopard in particular was a great release, with space and performance improvements. Since then, however, every release has bought a bit of a slowdown until Yosemite which reduced my former zippy performance to crawl.

Running an application was fine, but if I had several open, then switching between apps would be painful. In particular, MS Word would hang for sometimes a couple of minutes if I had not used it for a while. Then it would hang again when I tried to do a save. Just opening System Preferences could take a minute or two.

Economic Resonance: A theory for maximizing growth

Note: This paper is in progress and will take a few weeks to complete


The economy of the country is an aggregate of the economic activity of the various components: corporations, public sector, small businesses, families and individuals. While the specific objective of a capitalist corporation is to maximize return to its shareholders, clearly most companies do best when the overall system is maximized.

This paper will introduce a concept we call Economic Resonance that shows that the overall economy works best when in a state of “harmony,” and that it can be negatively affected when  accumulation by one sector is taken to an extreme. We will show that the when a balance amongst sectors is achieved, an Economic Resonance occurs that maximizes growth and benefits for all sector.

The Room
“Jenni Plochka?” the worn woman in a pink bathrobe read the card in a harsh, tobacco and booze voice. The blue “Vacancy” flashed through her cigarette smoke. She frowned suspiciously. “Don’t get many BMWs here.” “Just wanna crash. Gotta bed?” “OK. But we paintin’ and wirin’, so th’only room is an old one at the end.” [READ MORE…]

Apple developers conference – the coming revolution


The WWDC has come and gone with no announcement of an updated Apple TV nor network streaming. Still, rumors continue that the Apple is waiting to seal deals for the streaming. With all that was announced, it is likely what I discuss here is merely posponed.
As for the Apple TV – Jonny Evans at ComputerWorld writes:

HomeKit support has been present in the Apple TV firmware since v7.0, though Apple hasn’t discussed it.

So this, at least, is going forward.

On June 8 Apple (AAPL) opens its World Wide Developers Conference, a week long event for developers of apps for both the Mac and iOS platforms. The schedule is full of workshops and sessions that instruct software engineers and designers on the technicalities of the trade – how to program Apple products.

No session is more anticipated than the opening keynote address (10 AM Pacific time). Here CEO Tim Cook and cohorts will present several important classes of information:

  1. Key updates and statistics on the various platforms and products,
  2. Introduction of new versions of iOS and Mac,
  3. Possible introduction of important product upgrades.

The first point will eye-popping figures of product sales, usage statistics for various features such as Apple Pay, the number of billions of dollars that have been earned by iOS app developers, and so on. Hopefully, there will be some update on Apple Watch sales, a topic of great interest.

Number two is a longer section which will detail all that is new in the upcoming versions of the two operating systems. There are rumors that new features will be few as Apple may have focused more on improving performance. This is what it did with the Snow Leopard release, one of its most successful. However, there will be new features added to each system, but that is not my focus here.

In this article I will focus on number three. While there might be an upgrade to the Apple Watch – most likely with a new, faster processor, there is another product that I believe will take center stage.

Big Data – Forecasts

Big data is an emerging technology that is currently receiving a lot of attention. My earlier post gives a primer on some of the terms and issues.

Investors are interested in the potential for appreciation in this market. There are several recent forecasts.

ABI Research

ABI predicted:

  • Global spending on big data by organizations will … [reach] $114 billion in 2018.
  • The forecast includes the money spent on internal salaries, professional services, technology services, internal hardware, and internal software.


Wkibon expects growth from about $33 billion this year to $45 billion in 2018, and to $85 billion in 2026. The define Big Data industry as: Continue reading

Big Data: What’s the Big Deal? – A Guide

The largest tech companies are running to provide two new related services to big business, and the rush is on. These are cloud computing services, and big data analytic services.

The internet, mobile computing, the internet of things – all these provide new sources of data that did not exist ten years ago, and the quantity of data is enormous. Questions arise: how do you access that data, how do you organize it, and how do you turn it to your advantage?

These represent huge changes in the landscape of enterprise computation, and billions of dollars are at stake. Wikibon estimates total Big data spending in 2018 to reach almost $50 billion, while A. T. Kearney and ABI both predict $114 billion. Granted their definitions most likely are not the same, but in any case these are huge numbers.

Main Players include:

What is it all about?

There has been a lot of talk about these services, but many people are still hazy on what it all means. Therefore, I am providing a kind of primer for those not completely sure of what this movement is about.

I – Cloud services

The basic concept of cloud services is well known. Continue reading
