Happy birthday to my MacBook Pro

Let’s all wish my trusty retina MacBook Pro a happy birthday. I purchased it on 22 December 2012 in the Belfast Apple Store with cash from redundancy pay after I left Northgate Managed Services. It’s still the best computer I’ve ever owned or used. Very fast, even today five years later, and I see no need to replace it for the next few years. Assuming nothing breaks to force me to get a new one. The battery is still in good condition. I usually use it with power plugged in, but get four hours plus on the battery when required. The i7 Quad core processor is still more than enough for all the tasks I throw at it; the 8GB RAM has never been a problem. They didn’t sell 16GB models in the Apple Stores in 2012, and I didn’t want to be without a Mac over the holidays by ordering online to get the extra RAM.

It’s no wonder that Mac laptop sales slowed for a few years around 2012 and later. I used to replace my Mac every two years, or sometimes sooner. But the mid-2012 retina MacBook Pro got to a level where it was so good people didn't need to change them so often. They might be the best laptops ever made. When I do have to replace it I might go for a desktop iMac Pro beast and use an iPad Pro for my mobile computing needs. We’ll see.

One final note: the cost for the MacBook Pro in 2012 was £1799. Not cheap. But as the adage goes “You get what you pay for!” Spread over the five years that works out at 99p a day. Bargain. Or as was pointed out to me on Twitter, when the resale value of the MacBook Pro is factored in (about £500) then the daily cost drops to about 71p a day.

Deleted Xcode from my Mac

I deleted Xcode from my Mac. The two version I had installed were using 20GB of space on the hard disk. I haven’t used them for months. I just don’t have the skill or inclination to write software that I would be able to put on the Mac or iOS stores. I’ve enjoyed tinkering in the past just so I know what people are talking about in relation to Apple platform development. Other things interest me more now though. I’ll still keep REAL Studio on my Mac for the times I want to bang out a simple program for my own use. I’ll still keep up to date with GUI issues on the mac and iOS devices. So I’ll still be reading books about this. Like the excellent Tapworthy.

I guess this means I won’t be going to WWDC this year. I could justify it in the past but not now I think. Given the lack of Mac OS X Server content last time and the fact the Xserve is no more. Which may, or may not mean the death of Mac OS X Server as a viable server platform (let us run it in VMware vSphere!). It’s unlikely that the 2011 WWDC will have much enterprise ICT content to justify attendance for non-developers.

This means I may not spend at least a week in San Francisco in 2011. Yikes. Of course I have enough Marriott Hotel points and BA miles to go for a weeks holiday. Could even go WWDC week and sit in the sun to read & write during the day and have a few beers and concerts at night…


iPad as a blogging tool

Testing the WordPress app on my iPad. When I get my new Vodafone MiFi I’ll be using the iPad when out and about a lot more than my MacBook Pro. I also want to do a lot more blogging on a diverse range of subjects. Mainly from airports I expect 🙂

Well if you can see this post then the WordPress app works!

WWDC is imminent – Essential sessions

In 3 weeks it’ll be day 2 of WWDC. Day 2 is the start of the topic specific sessions. The Monday is taken up with the Keynote in the morning and Several State of the Union sessions in the afternoon. The State of the Union sessions are on things like Mac OS X Server, Graphics & Media, etc.

The majority of the sessions I will be going to will be related to management of Macintosh computers and integration into ICT infrastructure based on Microsoft Windows. Listed below are the sessions from those published so far that I’ll be going to. There are usually additional sessions added after the Keynote, to cover any new features that are announced, and there are also some brilliant Brown Bag sessions at lunchtime with external guest speakers (like Pixar). There are also evening events such as the Apple Design Awards and the Thursday Night Party. The Bare Naked Ladies were the house band for the party last year. Here’s a good picture of 3 reprobates watching them from just above and behind the stage 🙂

Here are the ICT management sessions I plan to attend:

I like BASIC!

I like programming in BASIC. There I said it. I can hear the purists poopooing, indeed some may be fainting. But it’s only a language. It has been said that modern versions of BASIC are not your fathers BASIC. What this means is that there are versions of BASIC available today that have most, or even all of the features found in other modern languages like Objective-C, C#, Ruby, Java, etc.

I’m a Macintosh guy. For a long while I used FutureBASIC but it has fallen by the wayside a bit. A good modern BASIC for the Macintosh is REALbasic. It’s actually cross platform and runs and compiles for Macintosh, Windows and Linux. I only have the Macintosh version. REALbasic has an object-orientated language with lots of modern features:

21st Century BASIC
Yes, it’s BASIC. But it’s not the interpreted, procedural, line numbered, spaghetti-code-producing BASIC from the old days. This is a robust, modern, fully object-oriented from the ground up BASIC that compiles to native X86 and PowerPC machine code. REALbasic supports inheritance, polymorphism, interfaces, delegates, introspection, the works. And if all of that made your eyes glaze over, don’t worry. The great thing about REALbasic / REAL Studio is you can do a lot without having to know any of this, but it will be there when you need it.

One downside is that it produces quite large binary files. REAL Software have made changes to the system to allow them to address this but at present it still links in everything and this gives big executables. I don’t think this is a problem these days. Another issue with the Macintosh version is that currently it uses the Carbon framework (mostly) for interface elements. Cocoa is what modern Macintosh apps should be using. The good news is that a beta that uses Cocoa is imminent. I’m looking forward to it. It should make it easier to produce Macintosh apps with REALbasic that have more Cocoa UI compliant interfaces using a language I know and I’m comfortable with.

Will still need to know Objective-C for iPhone apps though…


Back to programming basics

I bought myself a copy of the Pragmamatic Programmers Learn To Program book. I’ve decided to go back to basics and make sure I have a good foundation in the basics of programming before trying to build some applications I want for the Macintosh and iPhone.

Not because I have tried to build the applications and failed. I haven’t. No, I just want to build the foundations first before moving on to meaningful stuff. Sort of fill in some of the knowledge you’d get from doing a formal programming course at College or in first year University; but by self study. What is that term about a house built on sand…

In addition to the Learn To Program book, which uses the Ruby language for its examples and exercises, I’ve also got two entry level Objective-C books that I will be studying at the same time. These are Programming in Objective-C 2.0 by Kochan and Learn Objective-C on the Mac by Dalrymple & Knaster.

I’m going to use all three of the books at the same time by reading a chapter at a time from each. Is this sensible? Who knows? I’ll get back to you on that in a month 🙂


UK rejects privacy group’s gripes about Google Street View

Just bloody right too. Put the torches and pitchforks away folks.

The UK’s Information Commissioner’s Office has responded to complaints that Google’s Street View doesn’t do enough to protect citizens’ privacy by stating that removing Street View would be disproportionate to the relatively small risk of privacy detriment.
