iPhone 2G on O2 Simplicity contract

If you liked the concept of a new iPhone 3GS but found the contract tariffs and Pay & Go up-front costs unpalatable, now might be a good time to obtain a pre-loved iPhone 2G or iPhone 3G. I have an iPhone 2G which I previously unlocked and used on Vodafone UK, but found myself drawn to O2's offer of unlimited O2 to O2 calls—not to mention avoidance of the need to unlock the device and the hassle around firmware updates that doing so entails. I had to dig around the Interwebs and make a support phone call to discover all I needed to know to get up and running with O2 Simplicity; that knowledge is summarized below. Feel free to contribute any further tidbits! Know the limitations of your phone As a glance at this chart from Apple will show, tethering and MMS are not supported on 2G iPhones: © Apple Despite the implications of this chart, you can receive picture messages on 2G iPhones, in a roundabout way (see below). Incidentally, MMS will apparently work fine on iPhone 3G but tethering requires purchase of a bolt-on plan from O2, although can be enabled without easily enough—but doing so risks disconnection. Know the limitations of your tariff A Simplicity tariff isn't the same as an iPhone tariff; O2 couldn't really make the former too attractive or they'd cannibalise sales of iPhones on contract. For the clear benefit of a month-by-month contract at a lesser price, you have to give something up. Not a lot, to be ...

The dark art of AirPort networking

Until recently I was using the dodgy BeBox supplied by my Internet access provider as both a DSL modem and wireless router. The ST585v6 could create a wireless distribution system (WDS) to extend my home LAN to the attic iMac, but only over insecure WEP. So we bought a new dual-band (2.4 and 5GHz, 802.11b/g/n) Apple Time Capsule, thinking it would simplify connecting to an AirPort Express and at the same time provide wireless Time Machine backups with shared network-attached storage (NAS). In the event fully integrating this new device consumed hours, with victory arriving only after the discovery of occult keystroke trickery—not at all the Apple experience I have come to expect. Bridging WAN and LAN The first step was to get my BeBox working in bridge mode, functioning as a DSL modem only and handing over my public IP address to the Time Capsule. For the record (in case I need to repeat the exercise), Be sent me this advice: If you would like to, you could switch the BeBox into bridged mode, it would then behave entirely as a modem without routing function. To do this, please follow this procedure: Access the SpeedTouch configuration page by opening a web browser and typing in the Address Bar 192.168.1.254; Click on SpeedTouch > Set up; Click Next, then choose Multi IP 3 Data Ports; Click Next, then Start. After that your BeBox will no longer be accessible through the web interface and telnet server. This will set your be box in bridge mode. Things actually proved more ...

Latest tweets using SimplePie

It's taken me a while to warm to Twitter. I created the Quicklinks category on my blog for sharing things that didn't warrant a full post, but even that's too much effort sometimes—especially if it's just sharing a link. You might argue that's what bookmarking services like Digg and Delicious are for, but even then it's a multistep process. I've only recently become aware of just how well suited the Twitter API is to sharing links or updating your status message to multiple services with minimal effort. This post shares some PHP code to integrate your tweets within your WordPress blog, and code to simplify getting your WordPress posts into other people's tweets. The interconnectedness of tweeting A few examples: I use the Twitter updater plug-in to notify Twitter of new posts on my WordPress blog. Darkslide on my iPhone can post a Flickr image link via the iPhone Twitterrific app. Most of my links are discovered in my preferred RSS reader NetNewsWire, which can send these to desktop Twitterrific (News menu). The Twitter app for Facebook will update your Facebook status using your tweets. Twitter offer an RSS feed which can be used in conjunction with the SimplePie PHP library to bring tweets to your WordPress blog. This last example is the focus of this post. I will assume that you have already downloaded and correctly installed SimplePie for WordPress from here. A SimplePie template for Twitter Create a text file called tweets.tmpl containing the following: {IF_ERROR_BEGIN}{ERROR_MESSAGE}{IF_ERROR_END} {ITEM_LOOP_BEGIN} {ITEM_DATE_UTC}{ITEM_DESCRIPTION}# {ITEM_LOOP_END} Upload this file to the following directory on your server: /wp-content/plugins/simplepie-plugin-for-wordpress/templates/ Now for a little ...

Desktop refits with GeekTool and friends

Further to my previous post on how to get BBC weather feeds on your desktop, this article collects together other scripts for GeekTool I've come across and customized (hat tip to the original sources, which I neglected to record). Who says the command line doesn't have equal status alongside the Mac OS X eye candy? Suggestions for optimization/ improvement or additional useful scripts most welcome. Creating headings Create headings using an echo shell command, just as when using PHP. For example: echo " //UPTIME:" Within GeekTool you can specify a custom font face, colour and opacity, text alignment, accompanying icon, refresh time, and whether the output should be "on top" of other windows—as for any of the following shell commands: Reporting system uptime The following shell command will report system uptime: uptime | awk '{sub(":", "h ", $3); sub(",", "min", $3); print "Time since last system boot: " $3}' Monitoring memory usage Does you Photoshop work or toying in Parallels merit investment in additional RAM? The following shell command will allow you to monitor memory usage, showing the total RAM in use and top running processes (the window is sized so that the top 10 are visible): uptime | top -l 1 | awk '/PhysMem/ {print "RAM in use: " $8 " \n"}'; top -ocpu -FR -l2 -n20 | grep '^....[1234567890] ' | grep -v ' 0.0% ..:' | cut -c 1-24,33-42,64-77 Identifying CPU hogs Why is that non-essential utility app you just installed consuming 97% of your CPU cycles? The following shell command will allow you to monitor how much of ...

Live BBC weather using GeekTool

GeekTool is great fun and seems an ideal means of occupying the mind while avoiding something else you should be doing. This Preference Pane for OS X basically lets you create a "live" desktop, auto-updating with data extracted using shell scripts (which can themselves call AppleScripts), image overlays, or log and other text files. I found many inspiring examples around the web to appropriate for my own desktop (see here; apologies for failing to note sources)—but one thing I had to work out by trial-and-error was bringing BBC Weather into the mix. Assuming you already have GeekTool installed (free), go download and install Lynx, a command-line web browser available for OS X here (free). Now enter your town, city, country or UK post code on the BBC Weather website. Look for the "latest observations feed" link. For example, for Chesterfield the feed link is: http://feeds.bbc.co.uk/weather/feeds/rss/obs/id/3282.xml In GeekTool create a new shell script with the following command: lynx -dump http://feeds.bbc.co.uk/weather/feeds/rss/obs/id/3282.xml This will show you the text file that we will be working with, created from the RSS feed. Alternatively you might open the same URL in Lynx itself from the Terminal: In a TextEdit window (for editing convenience) we now write AWK commands to search for and pull out the bits we want. I found these articles served as a useful AWK primer. You can also search-and-replace text as in the following code to remove redundant commas: {gsub(/,/,"")}; Find a unique word on each line from which you want to extract text. For example, to refer to the line containing ...

Know your waypoints from your track points

Bruce — Tue, 26 Aug 2008 20:23:05 +0000

From http://www.bioneural.net doi:tSglPpAB7a8nfM :

Geotagging photos can be done manually or automatically. When using a GPS data logger in automatic mode your position at each point in time (intervals vary) is recorded as a track point. The collection of track points recorded during a logging session is called a track log. Some devices (e.g. GlobalSat DG-100, Holux M-241) feature a button for manual entry of a specific GPS location as a waypoint, which you can match to the corresponding photo(s) by hand. That all sounds pretty straight forward doesn't it? Well it's not, because some GPS devices can't tell their waypoints from their track points. Thankfully the aptly-named GPSBabel can translate us a way out of this misunderstanding for the DG-100, and an update to BT747 means you can now download waypoints from the M-241 to your Mac. It's not merely a question of semantics Contiguous track points illustrate a very clear path on a map: you can see exactly where you went and, at a pinch, use a pre-recorded track to follow in someone else's footsteps. What you can't do is readily identify particular locations, because when plotted on a map track points are indistinguishable from one another. Specific locations (waypoints) have a variety of uses, including manual geotagging of photos, mapping points-of-interest, indicating landmarks for direction-finding, or marking cache locations in geocaching. If you're looking to providing instructions you want others to be able to follow, an ordered set of waypoints (describing a route) is what you need. Lets look at some simple examples with ...

Publicizing WordPress post revisions

Bruce — Mon, 04 Aug 2008 09:26:22 +0000

From http://www.bioneural.net doi:tSglPpAB7a8nfM :

WordPress 2.6 introduced post revisions, a form of version control that allows you to review or revert to previous editions of a post or page on your WordPress blog. The value of this feature has generated some debate, largely because it's "on by default" with no easy toggle to disable it. The thing is notification of post revisions is private, within the admin interface. So how do you make the date of last editing public? One of my pet hates is undated web content; if there's no date I'll often move on without reading the page content. Sometimes you can glean the date of first publication from a post permalink, as in this example (day and name, in Settings > Permalinks): http://www.bioneural.net/2008/08/02/first-track-logger-for-iphone-released/ There are two problems with relying on this method alone: Did you first publish on August 2 or February 8? There are different ways of interpreting dates; It's only the date of first publication, not the date the post was last revised. Clarifying the date of publication One option is to time stamp the publication date in your theme (as many WordPress themes do), which introduces a little more flexibility to deal with the first issue by specifying the name of the month to combat ambiguity: A simple code snippet for this would be: Published by Bruce on August 4, 2008 Consult the Codex for options that allow you to customize the display of date and time formats in your theme. Showing "last modified" dates I've searched the Codex and the Forums for a means of getting the date of ...
