This is another of Michael Connelly’s thrillers featuring Mickey Haller, a maverick defines lawyer. In this one, Haller defends a woman who is accused of murdering the banker who was in charge of foreclosing on her home. Not only is the court case fascinating, but the back story of Haller’s complicated personal life is just as compelling.

IET Meetup – Only a Matter of Time
I was lucky to get a ticket to an excellent lecture by Leon Lobo of the National Physical Laboratory – ‘Only a matter of time’ – How time has infiltrated different industries and why it is important to a micro second level. This lecture was partly to celebrate 60 years since Louis Essen developed his atomic clock.
All attendees were presented with a copy of Louis Essen’s memoirs. I love reading about the history behind mathematical or scientific advances. This book includes gems such as when Albert Einstein gave a lecture at the National Physical Laboratory and someone had to lend him £5 because he had no money! Also noteworthy is that the great Alan Turing was developing a computer at NPL after the war – he just happened to cross paths with Essen, and repeated a key correction factor calculation for him, doing it far more elegantly and rigorously using waveguide theory.

ACCU: Testing Times
Pete Goodliffe wrote this excellent article (login to ACCU may be required) on how to test software. It’s a decent summary on types of test, who should write them, when to write them, what to test and suitable test frameworks. Anyone looking for a robust argument for why effective testing is vital should refer to this.

Book Review: One Shot, Lee Child
This book was the first Jack Reacher thriller that I read, quite a few years ago. That copy came free with a copy of the London Evening Standard newspaper – it was probably about 50p at the time, but has since become a free paper handed out to the commuters of London every evening. I particularly wanted to re-read it because of the description of Jack Reacher that starts the book.
This should be very useful for any Hollywood Producers who are looking to cast Jack Reacher in a film – particularly his height (6′ 5″), weight (220-250lbs) and chest (50″). Obviously, this is a big guy, and missing that point would be bound to annoy any diehard Reacher fans.
This is actually one of the better Reacher thrillers. The perfect case is presented to the police, James Barr is the obvious perpetrator of a horrific killing spree in Indiana. Even worse for Barr, Jack Reacher has seen it on the news and is travelling there to ensure he doesn’t get away with it. Yet there’s more to the case than first appears, calling for Reacher’s special investigative skills and his own brand of blunt justice.

Book Review: Mistress of Justice, Jeffery Deaver
According to the author’s note, the edition that I read is his re-write of an earlier book by the same title. This is the second re-write that I’ve read recently, the other being by Nelson DeMille.
On first impressions, the book has a dull plot – a promissory note is missing, and Taylor Lockwood (the lead character) has been asked to find it somewhere in the law firm. The intrigue comes from the plotting around the firm, where competing factions are fighting over leadership. The stakes are high enough for Taylor to be at risk of physical attack – and she sees both senior figures and younger up-and-coming professionals risking everything to get ahead.

Tutorial: Writing your first iOS App
I’ve finished working through this excellent introduction to writing iOS apps. Having written step-by-step guides for developers learning new software myself, it’s clear just how much work has gone into this guide to make it accurate as well as useful and informative.
- Having never used Xcode before, the guide did a good job of introducing the development environment and showing the workflow and how to manipulate the various views
- The FoodTracker application itself covers quite a few techniques – it’s a shame that some of the early lessons are later deleted as the app is built, but it’s a trade-off to get something to run quickly
- The frameworks clearly do much of the heavy-lifting. This reminds me of writing user interfaces in versions of Visual Basic – you didn’t need to know much of VB as a language, it was more about leveraging the tools to get a result
- Swift is very concise, parameter syntax takes some getting used to (some parameters have both external and internal names, which is esoteric) but even the passing parameters by name is starting to grow on me.
- It’s very cool that unit testing is integrated in the dev tools – I’m sure I’ll be writing plenty of tests against my data model when I work on this for real.
I have a couple of ideas for apps that I’d like to write for my new Apple Watch, so next I’m looking to try a tutorial specifically for a Watch app.

Book Review: The Scarecrow, Michael Connelly
Jack McEvoy is a crime journalist whose position has been put at risk – meaning he has only two weeks left in the job. As well as handing over to a younger, cheaper journalist, he decides to go all out to write a final, brilliant story to show his employer what they’re missing. And perhaps he’ll be able to finish his first novel too.
Rather than a newspaper story, McEvoy uncovers a serial killer. He hooks up with Agent Rachel Walling of the FBI in order to investigate. Now, Walling has also appeared in other Connelly books with Harry Bosch – e.g. Echo Park. I love it when authors recycle characters across stories, Jeffrey Deaver does similar tricks.
The investigation focusses on a web hosting firm with a highly secure data centre. The description of “The Farm” (the grid of machines hosting sites) is quite interesting, although it’s a shame that the technicians are so stereotyped (not everyone that works with computer hardware is a long-haired hacker!).
It’s a pretty good story – hard not to have sympathy with McEvoy (who’s ex-wife is quite successful whilst he’s left jobless with few prospects), and there are sufficient twists to keep one’s interest.

MIT develops file system with data guaranteed
Wired reports that MIT have used formal verification to write a file system that to probably will not lose data in the event of a crash.
Making sure that the file system can recover from a crash at any point is tricky because there are so many different places that you could crash. You literally have to consider every instruction or every disk operation
They used Coq, a proof assistant that enabled them to build the system from the ground up in a logically consistent manner.

Book Review: Protect & Defend, Vince Flynn
After the first Vince Flynn thriller that I read, my mind was made up not to read any more. However, my Dad recommended this one and I’m glad I persevered. This book features Mitch Rapp as a more established character. Where the earlier book sees him as a maverick agent, he’s now a senior figure, friend of the President and sage adviser on Middle Eastern affairs. Ok, so this is somewhat stretching believability, but it does make for an entertaining book!
What set this plot aside was that the storyline in Iran and ensuing political fallout was as intriguing as the action scenes where Rapp continues to be a master of his trade.

Video: Animations
I was interested to see how animations are executed for Apple Watch apps. These videos shed some light on it: WWDC 2015 Apple Developer Videos. I watched:
- Layout and animation techniques for WatchKit
- Designing with Animation
It seems that a lot of the animations are ‘tricks’ achieved by tweaking the layout groups (either changing size, alignment or visibility). Other recommendations include writing skeleton apps to mock animations by switching between images put together in KeyNote – this enables choosing between competing ideas without taking the time to code them all individually.
