The shot above is from my current Mac desktop. It’s fine during the day but the whites at night even with lights on are bright. This is where f.lux helps. It sits quietly in the background and will set the colour temperature of your screen to match your lights. It detects your location and will automatically switch to the new colour temperature at the right time.

At first it feels strange when you see the colour temperature changing but I find it really eases the strain on my eyes although I will admit it does look odd when you see the screenshot above of f.lux in aciton. You can easily switch to different temperatures to match your environment and I also set f.lux to dim gradually over an hour. Makes a big difference to the effectiveness in my opinion. Finally there is an option to temporarily disable f.lux to allow you to work on any graphics or photography too.

A handy free utility that isn’t new but will be a must install on any future computers I own.

Instant Heart Rate for iPhone (and also Android devices) is a £0.59 app that measures your heart rate. It does this via the iphone’s camera – thats the bit that initially put me off the app. How would the camera detect heart rate? Well, by enabling the flash the camera can detect your heartbeat by the colour variation as the blood flows through your fingers. Fire up the application, click on measure and the flash is enabled. Place your finger over the camera lens and wait a few seconds for the app to settle and start detecting. It will then measure for a few seconds and start displaying your heartbeat. Once measuring accurately you can then store your heartbeat and a simple graph over time will show your measurements. The hastily shot video below shows how quickly it measures your heart rate.

I was still a bit sceptical but a few other tests after badminton and cycling confirmed it’s accuracy, tying up exactly with the heart rate monitor on my bike. As well as measuring heart rates, the app will also measure your heart rate recovery. The app will measure your rate for 60 seconds after exercise and this can be used as a simple measure of how fit your heart is. Again the app will chart your heart rate recovery over time so if you’ve made a New Years resolution and fitness is a new goal this should give you a way of measuring progress over the year.

Couple of updates from after the podcast. The app doesn’t work on the iPhone 3G but does on the 3GS although it needs a lot of light to accurately detect your heartbeat. Secondly, the app is also available for Android devices but I’m not sure on pricing or which devices are supported.

A very simple app but great value for £0.59 and definitely an app that impresses people when they see it in action.

Alfred is still called a beta but it’s been rock solid so far in my usage. Downloading the free version from the App Store brings with it a host of functionality. Alfred is called via a keyboard shortcut which can be chosen by the user. I always use cmd+space for my launcher applications. So typing cmd+space opens the Alfred window and from there I can search for applications and files on my local machine or on the web. For example, type 1p and Alfred will start to list files matching the text 1p. As I’ve launched 1Password before, Alfred will present that as my favourite result.

If I don’t want to launch 1Password I can tap down through the returned results via he arrow keys or I can use cmd+number to open another file, contact etc. This allows for very quick searching and launching of applications and files. On a file or contact returned in Alfred I can press the right arrow key to conduct a series of actions – launch file, mail file, delete file etc. Alfred will never replace the finder for me but for seeking out a file to edit or mail on to a friend it’s far quicker than the default Mac tools. The free tool also comes with a calculator and spell checker as well as a variety of built in web searches. Type google searchterm and a Google search will be run for the given searchterm, opening in a new tab in your default browser. Custom searches can also be added so it’s easy to add a shortcut for Bing Images for example. As a free tool it’s great but there’s also a paid option for Alfred – the Alfred Powerpack.

The powerpack isn’t available via the App store as in app purchasing isn’t supported yet. Instead, buy the powerpack from the Alfred website for £12 and you unlock a far more feature rich tool. Fallback searching (if nothing is found then search via Google) is added plus the ability to e-mail form Alfred. However the bigger additions are iTunes and Clipboard extensions.

An iTunes mini player allows you to search and control iTunes not only selecting music and the usual play/pause controls but also rate music as well. A more useful feature is Clipboard History and Snippets. Launched via a separate shortcut or by typing snip within Alfred, the snippets extension will show you your clipboard history allowing you to easily copy old clipboard entries to application. Snippets allow you to setup a library of snippets for commonly entered text. I find that really useful for the podcast – I have path entries, twitter text, iTunes boilerplate text entered as snippets so I can paste them in when required.

Alfred is not only a very functional app but looks good with it as well. The original Quicksilver always looked great and although Launchbar is functionally more rich that both Quicksilver and Alfred, I find the performance of Alfred coupled with the better design to be much better (might be due to size of Launchbar index over time). If you already have Launchbar then the extra cost of paying for Alfred can’t be justified but if you’ve not tried a keyboard driven launcher before then fire up the App Store and try the free version of Alfred. I’m pretty confident that after a few days you’ll be paying for the powerpack version as the time saved over a few weeks is worth far more than £12.

Photographer’s Ephemeris is free and is an Adobe Air application so is multi platform. It’s easy to install and use and the results are great. Alongside the Air application a version has been written for iOS devices. This however is not free, currently retailing for £5.49 in the UK. This version is iPhone only at the moment but an update is coming which will move the application to being universal with iPad support.

The application is similar to the desktop version but I find it easier to use via the touch interface. Like the desktop version moonrise and moonset angles/times are also included alongside the ability to find out when the sun will appear from behind a hill – ideal for scouting out locations prior to a shoot.

It’s app’s like these that I find so compelling on mobile devices. Focussed, simple to use but very helpful.

The site is simple to use – visit, click on a screenshot and watch the video. Customisation is limited in that you can change the background although in future you can tweak the layout to support lists or a full screen grid. All video’s selected are in HD too. This was an instant bookmark for me, not only on my desktop, but on the iPad and iPhone as all video’s work on iOS devices too. Awesome.

Readability is a simple tool that makes reading on the Web more enjoyable by removing the clutter around what you are reading.

To setup Readability, visit the website and select a Style, Size and Margin. Then drag the bookmarklet to your browser bar. When your on a website and the clutter is distracting click on Readability. Take this TUAW article for example.

Small text, distractions in the right hand column. One click with Readability and it’s clutter be gone.

I now have a clear distraction free article with images preserved. Much easier to read. The buttons to the left hand side allow me to swap back to the true website view of the article, and taking advantage of the cleaner page, I can print the article or e-mail the article on to friends and colleagues without the normal distracting content being e-mailed at the same time.

Another use of Readability is when it comes to note taking. I capture a lot of web content in Evernote for future reference. By default the snippet tool can capture a whole page or selected text. I prefer to use a bookmarklet that first sets up a Readability view of a web page and then invokes the Evernote web clipper to capture the article and sync it to my Evernote account. The result is a far cleaner set of notes.

If you want a bookmarklet to do both then take a look at this Evernote forum post. I hope you find Readability as useful as I do – certainly makes for a more readable web.

Handbrake is open-source, GPL-licencsed, multi-platform and multi-threaded. The latest update to version 0.9.4 included over 1000 updates and a 64 bit version for Snow Leopard. It includes support for presets which come with Handbrake so it’s easy to create a video for Apple TV or iPhone – the settings are automatically set making encoding very easy. You can create your own presets so if you want to repeatedly output video in a particular format you can create a preset which guarantees the sam format each and every time.

There are a massive amount of settings and options in Handbrake which can affect the final output. You can see a preview of the video as it will appear allowing you to check for any quality issues before running an encode and you can add multiple video’s to the encode queue so Handbrake can run through your queue while your away.

When downloading Handbrake you can opt to grab the command line version instead of the GUI and that becomes useful when you want to automate your ripping process. For example, this fantastic tutorial – How-To: Automate DVD & Blu-Ray (Backup, Encoding & Tagging) on the Handbrake forums takes you through the process of ripping, tagging and moving your content automatically on the Mac – something I hope to be setting up in the new year. If you have any problems the forums are definitely the first place to visit as it’s a goldmine of information.

That covers encoding but what about playback? On the Mac Quicktime is the default video player but many install VLC as it supports many more codecs than Quicktime but there is an alternative – Perian.

Perian is a free, open source QuickTime component that adds native support for many popular video formats. A full list of the formats can be found here. Perian is easy to install and once complete it’s settings can be accessed via a Systems Preference pane. Like Handbrake there is an active forum where you can find answers to any questions but for me it’s been trouble free. A great plugin for any Mac, especially if your using yours for media playback.

ClickToFlash is a flash blocking plug-in for Safari with a few neat features. Firstly and most importantly it blocks Flash content allowing you to choose when you want Flash to run, not when a website wants to. To view the flash content, click on the box seen on the website with Flash inside it and the Flash content is loaded as per usual. This has the benefit of not only reducing CPU drain and increasing battery life but also making websites more readable, removing some of the in your face advertising that’s becoming more and more common. There are some websites though that you will always want Flash to run on so thankfully ClickToFlash has a whitelist which means Flash on those sites will always be loaded.

One other benefit from this plugin is on YouTube. YouTube is a Flash based video site but they have encoded many of their video’s in iPhone friendly H.264 format. ClickToFlash detects if an H.264 format is available and allows you to view that instead of Flash meaning the video is loaded in Quicktime. Happy days as the video looks and plays better.

If Firefox is more to your tastes there are a number of Flash blocking plugins available but the best I’ve found is Flashblock. This works like ClickToFlash without the added H.264 detection. These two plugins combined should give you a far better browsing experience on the Mac.

When you first start Reeder you enter your Google Account details and it then sync’s with your Google Reader account syncing unread items, starred items and your notes. If you have a lot of starred items or notes this first sync can take a while although you can change the amount of itms synced via Reeder’s preferences if you think this could cause problems. On first launch i could immediately see that Reeder was far faster than Byline at syncing feeds.

Another improvement with Reeder is how good the app looks. I much prefer reading articles in Reeder than in Byline. The buttons at the bottom allow quick sorting by data or feed and also viewing unread and starred articles. There is also support for a number of third party services – Instapaper or ReadItLater, Delicious or Pinboard and you can tweet or e-mail a story from Reeder.

The latest update also includes swipe support so that you can quickly favourite or read an article. Swipe left on an article to mark/unmark as favourite and swipe right to mark as read/unread. You can also quickly mark as read a number of articles and thankfully there is a warning before doing this step in case you select by accident. In usage so far I’ve had no issues in syncing with Google Reader and the app and the website have kept in sync.

One area that Reeder is poor in is offline reading. At first I didn’t think that Reeder had an offline mode but it does – one that is pretty buggy. When offline, selecting a post takes around 20 seconds to appear. I can only assume this is a bug and it’s not intended to work this way. Another issue with offline content is that images are not cached as can be seen in the screenshot above. These two flaws mean I still have Byline installed for when I’m travelling by air.

If the next update fixes these issues (which according to the dev’s Twitter stream it will along with even faster syncing) then Reeder becomes a must have app for anyone that uses Google Reader. If you never need offline access then it’s a must buy now at only £1.79.

Gapminder is a non-profit organisation founded by Rosling and his daughter which developed the software used in his video’s, software which was bought by Google in 2007. The software is flash based and can be ran on the website to compare a wide array of data from 1960 to 2006. It’s fascinating and eye opening when you start to play with the data available and also look at examples that other people have done.

The Gapminder website has an informative blog and also a large number of video’s highlighting talks form Rosling and the facts behind the data that can be uncovered.

You can also make use of the Gapminder software on your own Google document. Follow this guide to setup the data and then insert a Motion Chart gadget to visualise your data. If you don’t find the software useful I urge you to at least try the video’s as you won’t fail to find them interesting.
