Diet and fitness, 2012 edition

jkt — Fri, 18 May 2012 09:04:31 +0000

I can't believe it's been months since I wrote on this thing. I seem to go through phases, sometimes writing nearly every day for weeks on end, other times not at all.

For various reasons, mostly because I've seen a steady incline on my weight from a January low of 75kg (itself up from 72kg after Nepal) to a Monday high of 81kg, I'm paying more attention to what I eat, and what exercise I do. I'd like to get down to around 70kg (or higher, but as long as boyfat % is less than 15%)

Following some suggestions from a fellow geek who's being doing this for a while, I signed up for MyFitnessPal to keep a food, exercise and calorie diary, and Endomondo for an ad-hoc exercise/calorie calculator. This'll go someway towards keeping me on the straight and narrow calorific intake/expenditure wise.

I realised a number of weeks ago that I still haven't started cycling again this year. I think the wet weather and general cold has put me off; by this time last year I'd clocked many hundreds of miles. Now that Rae has a road bike too (happy birthday!), we'll go out regularly and I'll record those calories burned (calculated using HR and cadence monitors along with GPS data) into the MyFitnessPal diary. Yesterday, I ordered a couple of Garmin Forerunner 410 GPS watches with HR monitors; easier to carry around when going running. Another gadget to help with the recording of data.

Now, if only there was a way to automatically get it from all the devices into a central data store…

Reading Materials – February, 2012

Very light on reading this month as most of my reading time has been spent studying.

Homeopathy and its Kindred Delusions, Oliver Wendell Holmes. Following a lengthy discussion about the dangers of homeopathy and its promotion, I wanted to fully arm myself with an in depth knowledge of the theory behind it. This . . .

Reading Materials – January, 2012

jkt — Mon, 06 Feb 2012 08:30:19 +0000

Quiet month this month in the reading arena. Studying for the exam last Friday took up a lot of my focus and delayed the writing of this post. Here is what I did manage to work my way through:

Letter to a Christian Nation, Sam Harris. Sitting aside Richard Dawkins and Christopher Hitchens, Sam Harris launches his own anti-religious missiles, with each one landing smack on target. Written as an open letter to America, it easily translates over the pond and cleverly destroys most of the arguments used to justify religious belief. Running at only about 50 pages long, it can be easily read in an afternoon, and is well worth the effort, no matter which side of the divide you stand.
Steve Jobs: The Exclusive Biography, Walter Isaacson. Weighing in at over 650 pages, this was the bulk of my January reading. I usually shy away from biographies – there's only so much narcissism I can stand – but this was written more as a time-line of Jobs' life. Covering everything from his crazy fad-diets, questionable parenting choices and of course the creation and then resurrection of Apple, Inc, it's all here, the good, the bad, the (occasionally) very ugly. If you're interested in a complete overview of the man and his life, this is certainly the book to get it from.
Everyone Loves You When You're Dead: (And Other Things I Learned From Famous People), Neil Strauss. As writer, and eventually editor, of the Rolling Stone, Neil Strauss (of 'The Game' fame), publishes the parts of interviews which weren't appropriate for print at the time. I found the writing often hilarious, the content bizarre (the interviewees, not the writer). Most of the subjects I knew, which always makes this kind of book more interesting, but some I'd never even heard of; if they were in the Rolling Stone, they must have been important at some point. An easy read, but there are certainly more interesting books out there.
Get Out While You Can – Escape The Rat Race, George Marshall. More of a flick-through than a read. Covers most of the items already written about in the 4 hour work week, but with less humour. Can easily be distilled down to a couple of tenets: generate multiple revenue streams; selling information is financially more efficient than selling services; if you're working more than a couple of hours a day, you're wasting your life. I actually enjoy what I do for a living, so mostly pointless.
Economics in One Lesson: The Shortest and Surest Way to Understand Basic Economics, Henry Hazlitt. Excellent primer in economics which quickly starts by dispelling common myths. I identified with a number of the core-misconceptions with regards to macro-economics, and I hope the lessons learned will stay with me. Anyone who's gotten into dinner-time conversations which have involved the discussion of unions, economic policies, or anything else even remotely economics based, would be well advised to read this book; you'll immediately be more knowledgeable than many of the armchair economists trying to turn you to their point of view.

Amazon customer service: credit where it's due

jkt — Fri, 03 Feb 2012 12:21:48 +0000

I write about dreadful customer service a lot, but rarely when customer service has been outstanding. Well, today is the dawn of a new era. Or maybe I slept well or something.

The screen on my Kindle broke a few weeks ago. Amazon said they'd replace it without question. A week later, the replacement hadn't arrived. I called and they asked I wait another few days for delivery.

As of this morning, it still hadn't arrived.

I've just called them, went straight through to Kindle Support and they're sending another one out to me special delivery for Monday (they offered to have it with me tomorrow, but I'm not available to take it). While on the phone I mentioned the problems I'd been having with the case too. They've told me to throw it away and they've credited the amount for a new cover to my account.

This is exactly the sort of customer service which should be provided. I actually feel like they give a crap about me, about my custom, and they're keen to ensure I'm happy.

Thank you, and well done, Amazon, and especially to the reps who have helped with my problems over the past couple of weeks.

MacBook Pro for sale

It was completely refurbished (by the Apple Store in Covent Garden) in October 2011, with a whole new uni-body, trackpad, keyboard. It's as 'as new' as you can get; boxed, all the cables etc.

Brand new, it was 1950 GBP. That same spec, with the same hi-res (1680 x 1050 px) anti-glare screen, on E-bay is going for 1250. I'd prefer to sell to someone I know, and will accept 1000 (or make me a reasonable offer). I'll include insured shipping to anywhere in the UK, or it can be picked up from Orpington or Central London.

Let me know if you're interested – j (at) jkt (dot) im, else I'll go on e-bay next week.

FreeNAS == Mac OS X Backup perfection?

jkt — Fri, 13 Jan 2012 12:00:56 +0000

According to Linus Torvolds, I'm not a real man. But I can live with that; I don't want all my data uploaded for FTP mirroring.

The Tullett house is, laptop wise, almost exclusively MacBook Pro based. Sure there's a netbook which boots Linux and a couple of laptops which we're about to ship to The Gambia, but if they're nuked by some random disaster I don't really care.

Our laptops however are home to our entire photo collection and iTunes libraries. Add onto that all personal documents, some of which aren't in the cloud, and should disaster strike there will be a lot of tears.

A feature I've loved in OS X for the past few releases is Time Machine. As a sysadmin for over ten years, I've rolled one or two backup solutions. I'm still trying to find a decent alternative to Norton Ghost for Windows – it's a problem which should have been solved by free software by now! – but that's a subject for another post, as it's a Windows problem, not Mac.

If you do not have a Time Capsule, wireless backing up is difficult unless you've a spare machine and bunch of disks laying around. Oh, and time to configure Netatalk and a bunch of other stuff. These days, it's time I'm short of.

Due to a screw up long before Xmas, I ended up with three spare 2Tb hard drives, which have been sitting unused in a cupboard; the other three which had been ordered at the same time had already found a home.

During a talk on WGC (a chat forum I use) last week, I heard that there was a £100 cash-back offer on HP Microservers at Servers+; making the machine only £100 to buy. On the same day I was also pointed to an open source NAS project called FreeNAS. The seed was sown.

Saturday morning I took delivery of the Microserver, and within an hour had the three drives installed. Digging out a trusty old 2Gb USB stick, I installed FreeNAS and booted it up.

Within a minute I was presented with a functional GUI to configure the machine. Over the course of the next hour or two I learned about how to configure the software. Setting up a RAID-5 configuration – allowing for 4Tb usable storage from the 6Tb installed – I created two volumes of 1Tb each for the laptops, leaving 2Tb free for future use. Configuring access to the shares was trivial: click a few buttons to enable AFP and set permissions on the shares for the users. Done.

Configuring the Macs was also straight forward. With one running Snow Leopard and the other Lion, wireless Time Machine backups work out of the box (as opposed to earlier versions which required tweaks to the system's configuration.) Having selected the disk, the first backup – Rae's machine – started

200Gb was never going to be quick, especially going over a wireless network, so it took most of the day (and into the night) to complete the first backup. Futures ones will be quicker as they only back up new file or changed files. This morning I set my own laptop up to start its backup. At the moment the NAS is pushing 40Mbit, not too shabby, considering the data's going over the wireless network.

The other 2Tb will probably be reserved for sharing on the VPN Mesh which is still being set up. 250Gb each should be plenty, especially as the data will be replicated over multiple sites.

Mostly though, I'm happy to finally have automatic backups in place which don't require plugging the laptops into external drives – a manual step which is guaranteed to fail at some point, and indeed does when I get the notification that a backup hasn't been completed in ten days. How much work/data could be lost in ten days? It doesn't bear thinking about…

Samsung Galaxy Nexus: SMS sending delays

jkt — Thu, 12 Jan 2012 13:25:17 +0000

For Xmas, I got Rae one of the new Galaxy Nexus phones.

While a little large for my liking, the phone is pretty and Ice Cream Sandwich seems a decent incremental upgrade, despite a number of applications not yet being upgraded to take advantage of some of the features (the Facebook application doesn't synchronise contacts, for example).

One problem which has surfaced is serious and affects the functionality of the phone: SMSes are sometimes delayed on sending. By 'sometimes' I mean every day, but not every text.

Rae and I will communicate regularly throughout the day, and sometimes many hours will go between me receiving SMSes and then a number (3, 4, maybe 5) will come in at once, with exactly the same received time stamp. If I've sent her messages before the flood, everything looks on her phone as they're in chronological order, while on mine everything is out of whack.

The delay can be from a few minutes to many hours (I think five hours is the highest so far).

The latest over-the-air update was applied (it was bought off-contract so isn't locked to any provider and can receive updates as soon as they're available) on Monday and hasn't resolved it.

Any suggestions on the cause? Could it be a hardware problem, or is it most likely software? It's only surfaced since her phone changed.

Rae's on Vodafone, I'm on O2, if that's relevant (I don't think it is.)

Letting go; unsticking the brain

jkt — Thu, 12 Jan 2012 08:40:23 +0000

One of my goals for 2012 which wasn't on my list, is to work on certain aspects of my mental agility.

Some people have amazing skills of compartmentalising: when they're at work, that's all that's on their mind; at home they are able to switch off completely. Others, even if their upset-triggers are fired, they can either rationalise it quickly or it just doesn't seem to affect them. I'm jealous of both skills, and I'd love to acquire them.

The first I want as I believe it'll help me improve my productivity at work – I have an astounding amount to achieve here in 2012: get up to speed on risk, pass 7 exams, get up to speed on all the systems – while also improving my quality of life at home: I ponder over work things during the evening and it can attribute to reduced quality of sleep and decreased connection with what's going on around and who I am with.

Regarding the second, I have certain triggers – subjects or behaviours (started or enacted by others) – which either cause a mental upset which can and often does last days or weeks (the weeks are more what I call 'ripples' than constant focus), or anger (which I guess is a form of upset) which can last many hours.

The former (upset) is, I believe, influenced, perhaps enhanced, by my underlying anxiety issues. The latter (anger) is mostly generated by stupid people; I have an incredibly low stupid-person tolerance. Unfortunately, dealing with stupid people is par for the course. You can do your best to minimise their impact, but ultimately, if you want to stop them having any impact on your life, you need to eliminate them entirely. This, unfortunately, isn't possible.

Getting to grips with the triggers is another matter. I do, ultimately, know I have control over how things affect me. But transitioning from theory into practice is difficult to say the least. CBT would seem the route forward, but the thought of desensitisation training scares me (forcing myself to think of things which upset me, until they stop upsetting me). What would be beautiful is an off-switch I can press on certain things.

Is there a viable solution to either? What works for you? Am I asking for too much?
