+Randall Munroe proposed the awesomely geeky idea of geohashing via the xkcd comic and blag recently. The idea basically involves using the MD5 hash of a date combined with the opening value of the Dow Jones Index for that date to derive a latitude and longitude relative to a (generally your own) location.
+
+However there is a problem for those of us residing in Australia (and other locations with a time zone significantly different from EST). With the Dow Jones Index operating on US time its not possible to determine a geohashed location in Australia until about 23:00 AEST for a given date. No doubt others have thought of this but I suggest we use the All Ordinaries Index instead. With that out of the way we just need some enterprising sole with some spare time to implement a version of the map based on this.
+
+Update: More info on geohashing in Melbourne on the Visible Procrastinations blog.
+
+Another Update: Using the Dow on the weekend works well though. As over the weekend everyone is more or less synced to the same index.
+
+Final Update: The xkcd blag has a follow up article that clarifies the behaviour for Europe, Asia and Australia. It boils down to using the previous day's Dow Jones Index.

+A friend asked the following today, the reply was big enough I decided to post it:
+
+So Wes, you've had your iPhone for a week now - what are your initial comments? + +Pros / Cons? + +Has it changed your life? Has the battery life been crappy for you? Talk time OK?+ +Its definitely the best phone I've had. Part of that is due to the tight integration with Mac OS X, which obviously very few companies were going to pull off. As a device its brilliant to use and full of functionality. I'm loving the apps and decent browser. The WiFi is really nice at home. The iPod part obviously works as well and better than any prior iPod. + +The on screen keyboard is pretty much as described. You have to give it time to get the hang of it and you have to trust it. If you're typing a word that would be in the English dictionary you're best to keep on typing even if the word is way off. By the time you get to pressing space its usually selected the right word, which is selected automatically upon space. Two irritations with typing though. Its less likely to get shorter word right, particularly when there's multiple valid options. There's no way that I'm aware of to get a list of possibilities and choose the one you want. Of course being a small word means its not hard to fix and if you type it correctly in the first place then it isn't a problem at all. The other minor annoyance is when you get to the last word in a sentence that is mis-typed with a correct suggestion it appears the only way to accept it is to press space (and then delete the space) or grab a full stop. + +
I haven't missed MMS at all, especially with a decent email client built in that can talk to Gmail via IMAP and send photos to flickr that way.
+I have missed Todo functionality. I have no idea why Apple have not got this syncing. The support is there in iSync and todos sync with my old phone (Nokia 6280) just fine. I'm hoping that its one of these things that will make it eventually. There's two reasons I miss todo, one to track things to be done, the other is for reminders for things that don't have a duration (which can be put in as calendar entries). There is no way to do reminders without a duration at the moment. Having said that the calendar functionality is comprehensive. It supports multiple calendars, full editing, meeting acceptance and basically anything you can do on the desktop.
+
+
Another annoyance surrounds SMS. When on silent you only get a single vibration on new message, which is easily missed. My old phone did three, which was better. Also when you get an SMS my old phone would show an envelope on the black and white standby screen. With the iPhone you have to wake it up to see if you've got a message after the display goes back off.
+
+The AppStore is great, some of the apps are very well done. I'm really liking Byline, Twinkle, Exposure and MoPhoTo. I'm not much of a Facebook user but the Facebook app is very well done. It just the core parts of Facebook without all the crap. Of those five, three are free, one is free by ad-supported (with a pay for version available) and the other AU$12.99. I think that's a pretty good spread for some top quality apps. Some screenshots of these apps are scattered below.
+
+
Battery life is nothing brilliant as has been reported elsewhere. You'd probably want to change it every day. Today I watched a video podcast on the way to work, send a couple of SMSs during the day, added a calendar event, got a call from Steve, called the dentist, listened to music, read in Google Reader via the Byline app, read and updated Twitter via the Twinkle app and used the timer to cook dinner and its showing half battery. It was off the changer all last night too.
+
+A complaint of the old one was that the ringer and message volume was very low and easily missed. I've it plenty loud enough and its only on about three quarters. Speaking on the phone the volume is good, although I haven't tried extreme environments like a club.
+
+One of the best built-in apps on the whole phone is maps. Whenever you want to find something, or get the details for a business, get directions, just bring up Maps and it will sort it out. Its as good as, if not better than Google Maps on the desktop. It has the same three views too: Maps, Satellite and Hybrid. The location awareness is great and there's some basic uses of it in the apps so far, hopefully more creative uses come out. One interesting one is an app called Exposure that is a flickr client with a 'near me' function. It shows photos near your current location. Doing so at home brings ups photos of St Kilda Rd, the fountain in the gardens out the front (Pictured above).
+
+Maybe I'm easily sold on such things but the UI is truly beautiful and being solely finger driven is revolutionarily (on a phone). I'm a happy customer.
+
+

In August 2006 some friends of mine bought me a Cumquat tree (alternate spelling Kumquat) for my birthday. This was a great present as my balcony was in need of some vegetation and what better than a little fruit tree. Its grown a bit since then and started to bear fruit for the first time late last year. In February Amanda and I move to a new place. The tree came with us and continued to grow more fruit.
+
+
Early in 2008 I decided to try making some liqueur with the Cumquats. Today I decided there was finally enough fruit to make the liqueur. I bought a couple of 1.5L preseving jars from Chefs Hat, a bottle of brandy and some sugar. The recipe I used called for 700g Cumquats, 700mL of brandy and 700g of sugar.
+
+I sterilised the jars by giving them a wash then putting then in the oven for 10 mins at 150ºC. I boiled the rubber seals for 10 mins as well. After letting the jars cool down I divided the ingredients evenly between the jars. The cumquats were added first, each one washed thoroughly and pricked with a fork several times. These were followed by the sugar and then the brandy. I'm not sure if all the sugar is supposed to dissolve. The recipe didn't say anything about it so I just left it.
+
+Now the waiting begins. The jars will be sitting in a cupboard for the next six months, with a bit of a swish around once a month. Hopefully come May next year the liqueur will be ready for straining and sampling.
+
+

For the month of November this year I'm particpating in Movember. At the beginning of the month I started clean shaven and for the remainder of the month I'm growing and maintaining a moustache in order to raise awareness of men's health issues. In particular depression and prostate cancer. This photo to the left shows my progress after the first two weeks (yeah its hard to see, the colour blends in :-) ).

On new years eve I welcomed the beginning of 2009 at Sensation, the self proclaimed "worlds leading dance event". Sensation started in The Netherlands, being held at Amsterdam Arena. When I first stumbled across videos and music from the Amsterdam events several years back I was in awe of a dance party that managed to pull 40,000 people. Well based on what I saw at Tel$tra Dome I think they managed to pull off the same thing here. Seeing the stadium packed with so many people all dressed in white was truly awesome. The music did not disappoint either. However I think I had built up an expectation of more of a "performance" aspect to the event, as this didn't seem to quite meet my expectations. Nonetheless a great night was had by all. Also special thanks to Hayden for using a number of his comped Deluxe tickets to get us in for free and skip the queue. Photos and movies from the night are on Flickr.
+
+Leading up to Sensation the media had a field day in regard to a select minority that took a bad batch of GHB at the X-Qlusive event and ended up in hospital. Now taking GHB in the first place is stupid but the way it was reported was just reckless and inaccurate. Not only did they harp on about this minority but the Herald-Sun managed to attribute the overdoses to totally the wrong event: Christmas Kandy, which was cancelled as a result. In the days leading up to Sensation I heard a news report on TV refer to Sensation as, "controversial" and you could tell they were just waiting for a repeat of what happened at X-Qlusive. Funnily enough it seemed that everyone at Sensation was very well behaved as I didn't hear or see a single report in the following days about any drug related problems (no news is good news?). I think its a great win for the people and the rave scene that the media didn't get what they wanted. Especially considering it probably the biggest "rave" type event to ever be held in Melbourne.
+
+I hope to see it held again next year as I'm certainly up for going again. Who knows maybe they'll bring Sensation Black here as well.

Back in December there was a post on the Gmail Blog which gave instructions on how to get some stickers for the cost of postage. I thought I'd try it out so I sent them an International Reply Coupon (IRC) (something I'd never heard of before) and what do you know they showed up today. They managed to come all the way from San Francisco in an unsealed envelope too. Now to decide what to stick them to... and who to give the unicorn one to.

+I read a post by Jakob Nielsen today titled, Weblog Usability: The Top Ten Design Mistakes. It was written back in 2005 but is still very relevant to today. The eighth point, "Mixing Topics", which states, "If you publish on many different topics, you're less likely to attract a loyal audience of high-value users" seemed particularly relevant given the diversity of topics in my recent posts. As a result I've decided to stop posting geeky content on this site and instead post that to my somewhat neglegted software site, Binary Trance (which needs a redesign). So if there if there is anyone out there that wants drop the personal stuff or keep getting the geeky stuff I suggest you check it out. If you're just after the feed I can save you the trip: Feed for Binary Trance Blog.

+This weekend Amanda and I embarked upon our first attempt at once a month cooking. The theory goes that you spend a weekend buying and cooking in bulk and then don't need to do it again for another month. Given we both aren't keen on cooking when we get home from work this allows the meal preparation to be simple and quick, without resorting to frozen pizzas or trips to KFC. It also has the potential to be cheaper since you can buy in bulk.
+
+
We selected a number of pasta dishes including typical sauces such as Bolognese but also did a lasagne and spinach and ricotta cannelloni. To add some variety we also included some double batches of massaman and Thai green curries. For snacks we baked some choc-chip cookies and choc-caramel muffins. Most of these weren't from scratch. Packet mixes, pre-made curry pastes and bottled pasta sauces were used to keep things simple also also allow the meals to be done quickly allowing us make more in a day.
+
+It is pretty tiring standing at the bench for hours on end so we came up with a system of one hour shifts. One of us would cook whilst the other did lighter tasks around the house, which worked well. It also avoided the problem of, "too many cooks in the kitchen...".
+
+The end result is a very fulll freezer as the photo on the left shows. All that should keep as in dinners and lunches for a couple of weeks. We don't have the freezer space to do a full month's worth although we have the ingredients to do the second fortnight of meals without another shopping trip.

I was sorting through some old postcards that I bought during the trip around Australia my family did in 1992. Amongst them was this particular one. Now that I'm not twelve and obsessed by tractors and earth moving equipment it seemed quite bizarre. The caption on the back reads:

Last week while we were still on holidays Manda and I got a good deal on Wotif for a night at Linden Garden's Rainforest Retreat. We set off in the morning and had lunch at Cloudhill Restaurant and Gardens. After lunch we wandered around the many different areas of the garden. The hedges and geometric alignment of the gardens were very cool.
+
+After that it was time to check-in at Linden Gardens. Google Maps gave us a dud route that sent us down a few interesting roads but we made it in the end. Our lodging for the night was "Sanctuary Tower", a three level mini-house with great views. After an in room massage we had a nice dinner at Wild Oak Restaurant just around the corner. The food was excellent and the servings very generous.
+
+The accommodation was fantastic, right down to the graphic design of the web site and stationary. There were lots of inclusions and thoughtful extras. The one complaint was that the bedroom was quite light when trying to sleep given not all the windows had blinds.
+
+In the morning we wandered around the gardens. The rainforest plans seem to have been planted some time ago and now it has that real rainforest feel. The paths in particular stood out as they were totally green with moss. After that it was time to go, it was a short but most enjoyable stay.
+
+Photos of Cloudhill and Linden Gardens are on Flickr. Given the lovely weather we had I also took the opportunity to take bracketed shots to deal with the extreme range of light. I then merged them with the newly updated Bracketeer.

The end of 2009 saw Melbourne's second Sensation held at Etihad stadium. I was fortunate enough to attend for free again and was once again impressed by the spectacle of the show and tens of thousands of people in white. The crowd seemed smaller than last year but there were still more than enough people to give a good atmosphere.

+A selection of photos from the night are on Flickr along with some movies on Vimeo.

+Ever since the now very quiet drunkenbatman hosted the Evening at Adler and Gus Mueller posted, "How to become an independent programmer in just 1068 days", its has been a goal of mine to one day live the indie Mac developer dream.
+
+Over the years I've dabbled in Mac OS X development but have struggled to find the time in between a full time job and also having a life to be able to see something through from start to finish. I'm convinced the ideas are sound because frequently others eventually release similar products. My last endevour was for a better archiver than that provided by the Finder. It was to be dead simple, taking interface cues from things like AppZapper. I discovered a little while ago that the fine folks at Apimac had created Compress Files, which implemented my ideas and more.
+
+Frustrated by this lack of time I decided to do something about it (after a small helping of procrastination). Last week I successfully negotiated a reduction to 4 days per week at my day job, with the fifth day allocated to Mac development. The first day of my new job is Mon Feb 11, 2008. However I find myself with a bit of a problem, I don't have any current projects to actually work on. Heeding the advice in Gus' post for Lesson #1 I'm seeking ideas from the Mac using community for a small application that I can use to get started. So if you got an idea for a small application that you don't mind sharing feel free to post a comment and let me know, it might be just what I'm looking for.

+Strangely enough I had the need to determine if it was possible to create a valid but empty tar file. Turns out it is. The method varies slightly depending on your flavour of tar program, here's how to do it on three of the big ones:
+
+BSD
+tar cvf empty.tar --from-file /dev/null
+
+GNU (Linux)
+tar cvf empty.tar --files-from /dev/null
+
+Solaris
+tar cvf empty.tar -I /dev/null
+
+Now if you wondering why I would want this, here's the explanation. I work on a batch processing system that processes files delivered from other systems. In some cases its necessary to wait for a file to arrive but give up after some time. In order to give up we copy an empty file (automatically) so that the processing proceeds normally. Ordinarily this is an empty plain text file but for the system I'm working on I'm expecting a tar file, hence the need for an empty one.

+An interesting email passed through the webkit-dev mailing list today. In what appears to be a small glimpse into what goes on in preparation for a Stevenote, Geoffrey Garen (Apple) noted in a reply to an email from Akos Kiss (Department of Software Engineering, University of Szeged, Hungary) that one of the reasons WebKit likes to do its own thing and not depend on code it doesn't own is to be able to fix problems with very short notice. Citing the example of, "12 hours before a keynote address".

Right. We're also reluctant to rely on code that we don't own. We've seen very large performance wins from tightly integrating and customizing all the components of the web stack.

+For my current software project I have the need to decode MP3 files for the purpose of producing an audio waveform. It doesn't need to be overly accurate as the decoded samples will be displayed, not played. However it does need to be fast, as a typical use case for the application will be MP3 files of around 100Mb (full length CDs). The application is for Mac OS X, although the results of my testing below could be useful for other platforms.
+
+Assisted by a code sample from Apple I wrote an initial version of the decoder that would read the source MP3 file and write the raw linear PCM data out to a file. I did this using the Core Audio framework built into Mac OS X. Once the program was working I tested it against some sample files and came to the conclusion that 4 seconds to decode a 3 min track was great but over 100 seconds for a full length CD, not so great.
+
+I did some searching and came up with two other libraries that seemed well suited to the task of MP3 decoding, they were mpg123 (libmpg123) and MAD (libmad). mpg123 had claims of being very fast, mad claimed it was very accurate.
+
+--enable-speed option. With the help of example code I made programs out of each that were comparable to the first version for Core Audio. I.e. MP3 file in, 16-bit Linear PCM audio samples out.
+
+To provide a benchmark I wrote a script that would run each of the three programs against a source MP3 file. Each program reported the elapsed time (via time(3)) and the processor time (via clock(3)) when it finished decoding. The programs were run one after another on the source file 10 times. Their PCM output was written to a new file for each invocation.

+Can people please stop using the 'feed:' URI scheme for links to feeds on web pages. Its annoying and unnecessary.
+
+From what I can tell this URI scheme was proposed around Dec 2003 as an unofficial pre-draft RFC. The reasoning behind the proposal was:
+
+...to provide a straightforward way for end users to subscribe to the data feed for a particular online resource while browsing the World Wide Web. The expectation is that clicking on a hyperlink that points at a "feed" URI will cause the Web browser to invoke the specified handler for the "feed" URI scheme which SHOULD provide the user with information about the data feed as well as the possess the ability to subscribe to the feed.+ +Fast forward to 2008 and all the major browsers have support for discovery of feeds specified by the link tag and a user interface to access them. Additionally they are able to auto-detect a feed when specified with the normal http URI scheme. With the built in support the browser is able to launch the appropriate feed reader on the system, be it within the browser or an external application; thus removing the need for the URI to be specified with the 'feed:' scheme. + +It seems use of the scheme really took off around the release of Safari 2, which included RSS support. When viewing a feed in Safari it presents the URI using the 'feed:' scheme, thus making its use highly visible. + +
+
+I understand that using the scheme makes it easy at an operating system level to associate a particular application with the scheme but it should be entirely internal an invisible to the user. The reasons its use irks me is when adding a feed to Google Reader its necessary to copy and paste the link and then remove the 'feed:' at the start. Additionally Firefox removes the colon from http, meaning that has to be replaced too. Okay so I'm lazy but all the hassle can be avoided by simply linking to the feed with the normal 'http:' scheme.
+
+As an example I'll pick on the MildMannered Industries Blog solely because its the first example I could find. The link on the page1 (at the top) is feed://http://www.mildmanneredindustries.com/blog/?feed=rss2, which when copied via Copy Link Location in Firefox becomes feed://http//www.mildmanneredindustries.com/blog/?feed=rss2.
+
+The other issue I have stems from the terrible DNS or proxy (not sure which is to blame) setup here at work. When a request is made for a hostname or scheme that doesn't exist the browser hangs for about 2 minutes before returning an error generated by the proxy. This happens in all browsers and means that if I click in a feed: link my browser hangs for 2 minutes, which is quite frustrating.
+
+So my request to the wider Internet community: Please stop using 'feed:'.
+________________________
+1. The related link embedded in the <head> section is correct (I.e. without 'feed:')

+I use vim coupled with the SuperTab plugin for my text editing and auto-completion needs. In some vim setups (E.g. Mac OS X) it is configured by default to search included files when completing words. This sounds like a useful feature but it turns out not to be. It has a habit of searching the include files of system libraries and modules, the keywords of which you rarely want. Its also quite a slow operation as it trawls through all the files. The solution is to add the following in your .vimrc file.
+
+set complete=.,w,b,u,t

+This is the same set of flags as the default except with the 'i' option removed. See the help for the 'complete' option for an explanation of what each flag means.

This is handy for when you want to see other comments posted without having to remember to check back. The problem is many WP themes don't provide a link to the feed.

+ ++iPhone Doesn’t Respond
++
+- iPhone may be low on power. Connect iPhone to your computer or to its power adapter to charge. See “Charging the Battery†on page 33.
+- Press and hold the Home button below the screen for at least six seconds, until the application you were using quits.
+- If that doesn’t work, turn iPhone off and turn it on again. [See Restart iPhone above]
+- If that doesn’t work, reset iPhone. [See Reset iPhone above]
+
Mainly included this quote for this point on force quitting apps.
+ ++iPhone Is Too Warm
+If the interior temperature of iPhone 3G exceeds normal operating temperatures, you may experience the following as it attempts to regulate its temperature:
++
+- iPhone stops charging
+- display dims
+- weak cellular signal
+- temperature warning screen appears
+Important: You cannot use iPhone while the temperature warning screen is displayed except to make an emergency call. If none of the above measures succeeds in lowering the internal temperature, iPhone automatically goes into a deep sleep mode until it cools. You cannot make an emergency call when iPhone is in this mode. Move iPhone to a cooler location and wait a few minutes before trying to use iPhone again.
+
Interesting that this calls out the iPhone 3G specifically.
+ ++ +The iPhone User Guide, optimized for viewing on iPhone, is available at: help.apple.com/iphone
Pressing the number/symbol button and sliding to the appropriate key is a quick way of adding punctuation and single numerals.
+Time scanning after sitting idle is a strange UI anomaly. Could be related to network time.
+There's an interesting section on Backups and managing them in iTunes that I won't repeat here, pp. 139.

Hello from my new 16Gb white iPhone. I was 5th in line. :-)+Unbeknownst to me at that time, my phone had helpfully attached the default signature of, "Sent from my iPhone", at the end of the email. Later that day, in a reply to what may have been my third ever email from the phone a friend said:

The reason being including the signature tells the recipient that the message came from a small handheld device, whilst I was on the go. This may help explain why the reply is terse and why there may be typos or particularly in the iPhones case, whole word substitutions. The phone is generally pretty good at auto-correction but if you're typing away furiously its easy for mistakes to go unnoticed. So, with a genuine desire to have a signature that wasn't about big-noting the fact I owned an iPhone, I explained the situation to my friends and asked what exactly was it that they disliked about it and how could it be made better and/or less intrusive. + +I got several well reasoned responses.

+I've recently upgraded from a Power Mac G5 to a Mac Pro. Since this upgrade also includes a switch of processor architecture I've been making a point of re-downloading all the apps I use, instead of just copying them from the old Mac. I'm doing this for two reasons. Firstly it ensures the apps are all up to date1 and secondly I ran Xslimmer over a lot of apps on the G5, which removed the Intel binary from Universal apps.
+
+This process has made me somewhat aware of a few apps that have seen little or no updates in quite a while. For some reason I have an expectation that applications will see periodic updates, say every six months or less. This expectation seems to stem from the fact I've paid for all these apps, which seems to bring with it some expectation of updates. Whether or not this expectation is justified or not is certainly up for debate. I clearly purchased a tool at some point and it performs its job fine, so I got what I paid for. I guess the expectation comes from not wanting to think you've bought abandon-ware and that software is one of those things that tends to continually evolve.
+
+In some cases I think the authors of the software fuel these expectations by explicitly indicating that there will be future development or by implying there will be updates. The following are some examples of what I'm talking about:
+
+There are some amazing things in the works for Disco. First and foremost, as Apple adds support for Blu-ray to their computers we intend to be right there with them. As soon as possible, Disco will support these new media technologies to the fullest. We're also planning on introducing more innovative features in the vein of Discography, Spanning and the new Disc Naming.+ +Obviously we're still waiting for Apple to bring us Blu-ray however despite the claims of future enhancements in the last sentence there have been no significant new features since the 1.0 release over 18 months2 ago. The last maintenance release was six months ago. + +
Ignore insecure directories and continue [ny]?
+
+Pressing 'y' becomes a bit tedious after a while so I decided to track down these insecure directories and fix them.
+
+man zshcompsys reveals the following about the security check:
+
+For security reasons compinit also checks if the completion system +would use files not owned by root or by the current user, or files in +directories that are world- or group-writable or that are not owned by +root or by the current user. If such files or directories are found, +compinit will ask if the completion system should really be used. To +avoid these tests and make all files found be used without asking, use +the option -u, and to make compinit silently ignore all insecure files +and directories use the option -i. This security check is skipped +entirely when the -C option is given. + +The security check can be retried at any time by running the function +compaudit. ++ +Running compaudit revealed the following: +
% compaudit
+There are insecure directories:
+/usr/share/zsh/site-functions
+/usr/share/zsh/4.3.4/functions
+/usr/share/zsh
+/usr/share/zsh/4.3.4
+
+Examining the permissions on these directories showed they were all group writable.
+
+% ls -ld /usr/share/zsh/site-functions
+drwxrwx---+ 2 wmoore mkgroup-l-d 0 Sep 4 10:54 /usr/share/zsh/site-functions
+
+Stripping them of the group write permission fixed the problem and made starting a new shell a little more pleasant.
+
+% chmod g-w /usr/share/zsh/site-functions /usr/share/zsh/4.3.4/functions /usr/share/zsh /usr/share/zsh/4.3.4

Since I got my iPhone I've been trying to find a suitable case for it. As I mentioned on Stephen's blog back in July I was looking for a pouch style case. I wanted something a thin as possible but not something that was permanently on the phone. I don't see the point of buying some thing with excellent design then wrapping it in some ugly case. I've been dropping into phone shops now and then to see what cases they've got but hadn't found anything compelling until this week. I saw that TeleChoice seemed to have what I was looking for, it also happened to be a Mossimo case. There is one problem that I didn't notice in the shop though.
+
+The case itself is almost exactly what I'm after: it's a vertical slip-in genuine leather pouch with a soft liner. There's one glaring fault though, which is the inclusion of a metal eyelet. The eyelet will of course get pressed against the phone and damage it over time, especially when in a moving jeans pocket or similar. I haven't yet decided what to do about. Options include removing it, putting tape or something over it or putting a little piece of tape on the phone.
+
+|
+ |
+ |
`dpkg -l` on the old server. The solution I came up with was as follows. Its not particularly elegant but got the job done:
+
+# On old server
+aptitude search '~i' | grep -v 'i A' > ~/installed.txt
+# scp installed.txt to new server
+# Then on new server
+aptitude search '~i' | grep -v 'i A' > ~/installed2.txt
+# Then determine which ones the new server doesn't have already
+diff installed*.txt | awk '{ print $3 }'|sort |uniq
+
+I joined the resulting list into a single line (Text > Unwrap Selection in TextMate or :%j in vim), removed a few that I didn't want then did sudo aptitude install and pasted the list of packages from TextMate. The aptitude search '~i' lists installed packages, the grep removes ones that were automatically installed and the diff finds ones that the new server doesn't already have.

+Today I followed my own directions on installing Consolas on my Mac Pro. The original directions were put together when installing it on my Mac Book. The downloaded disk image had a different volume name, as did the meta package.

After doing so and setting it the same as it was on my Mac Book (13pt, antialiasing on) it looked terrible on the Mac Pro. Compare the two images below. I was after the latter. +
After a little bit of confusion I decided to check the font smoothing style in the Appearance preference pane (in System Preferences). Turns out it was set to Automatic (best for main display) on the Mac Pro and Medium (best for Flat Panel) on the Mac Book. Changing to Medium and relaunching Terminal had it looking identical on both machines.

+Debian GNU/Linux 5.0 was released on Valentines day 2009, "after 22 months of constant development", according to the announcement. 22 months is still a long time between releases but its certainly an improvement over the nearly three years between 3.0 and 3.1 (sarge) and consistent with the 21 months between 3.1 and 4.0.
+
+As always the upgrade procedure is straightforward and worked seamlessly for me. I followed the instructions on go2linux.

+Virtualisation software has been around for a long time. This software allows you to host one or more guest operating systems on top of the one you're already running at near full speed.

Since starting my new job at Tricycle Developments in January I've been working on a project to repurpose the Reddit source code into a kind of community blogging platform with voting and karma.
+
+The result of that work went live on Thursday and after an initial hiccup with a questionably named user posting off topic content its going well so far. One of the first posts on the site is one asking for feedback on Issues, Bugs, and Requested Features. The thread has been inundated with all three of these so it looks like I still have plenty of work ahead refining the user experience.
+
+As well as being the first site I've worked on from start to finish (aside from personal ones) Less Wrong is also my first Python project and significant open source project. Its been great learning another programming language and putting that knowledge into practice. You can check it out the code on GitHub (pun not intended). Also if you end up looking at or using the code or Less Wrong itself and encounter any issues there is an issue tracker on Google Code where they can be logged.

+
+Today I was pointed towards a video on the Today Tonight website (an Australian current affairs TV show) and told to save a copy. Our client had gained approval to use the video on their site and needed a copy for that purpose. It was a flash video and whilst I've never saved one before I knew there were various tools out there to do it.
+
+My first attempt was a couple of different Firefox Add-ons. None of the three I tried would tackle this video, they save the empty player and a few ads but that was all. After some Googling I jumped on a Windows virtual machine and tried out Orbit Downloader. Its use was a little convoluted but it did indeed seem to identify the RTMP stream and attempt to download it. Unfortunately I think the host was blocking it and it just sat in a loop successfully connecting, then retrying.
+
+
Next up I found FLV Recorder it wasn't immediately obvious how to get it up and running but after following one of the many guides on the site I discovered that I had to tell it what network interface to listen to. I assume that it eavesdrops on the interface to detect and record the video stream, which is pretty cool.
+
+After the interface was selected I was on my way. I clicked the record button, loaded the webpage and started the video playing. FLV Recorder detected the video and started capturing it. As it is capturing the network traffic it's necessary to let the video play all the way through in the browser. A few minutes later and I had my video. I was able to play it back in the built-in FLV player before uploading it to YouTube.
+
+During my attempts I was able to determine that video itself was in Flash video format (FLV) being transferred using RTMP, which according to Wikipedia is, "a proprietary protocol developed by Adobe Systems for streaming audio, video and data over the Internet, between a Flash player and a server". It seems that the Flash player itself implements RTMP, which I think is why the Firefox Add-on's weren't able to see the network activity.

+mate . in a directory. This works great until the directory or one under it contains large, irrelevant files like log files or database dumps. Its at this point you start encounter massive slow downs in the otherwise very useful 'Find in Project...' function. The slow downs turn into crashes if the files are big enough as this results in TextMate atttempting to grab vast amounts of memory. Eventually the OS tells it to, "bugger off, 1Gb is all I can give you", or something along those lines.
+
+A common solution, particularly when working on Rails projects is to create a shell alias that just invokes mate with the directories of interest. This works ok but given I'm working on a mix of project types (Pylons, Rails, Radiant) I wanted a solution that did the reverse: Choose everything except what I want to exclude. Informed by an answer to a question on Stack Overflow I came up with this:
+
+As the comments in the script note I have this in a file called 'ate' in ~/Local/bin, which is in my PATH. I can now happily go to any directory, type ate and have it ignore that list of directories.

+On a number of sites at work we employ a static file caching extension to do just that: create static files that are served until the cache is invalidated. One of things that will invalidate the cache is deploying a new release of the code. This means that many of the requests after deploying will need to be generated from scratch, often causing the full Rails stack to be started (via Passenger) each time. To get around this I came up with the following to use wget to spider each of the URLs listed in the sitemap.xml. This ensures each of the major pages has been cached so most requests will be cache hits.

+This week I wanted to write a script that would get my account balances from nab Internet Banking. These types of things are generally quite simple with Ruby and Mechanize. I got the basics of the script up and running fairly quickly but when I ran it the site always rejected my username and password.
+
+After a lot more time in the Safari Web Inspector I finally worked out that the site actually expects the password submitted to the login page to be 'mixed' with a key that is unique for each page load. The 'mixing' (for lack of a better description) is performed by a javascript function. After I reimplemented this function in my Ruby script I was then able to sucessfully login and retrieve my account balances. My code is supplied below for anyone else who is wanting to do something like this.

+I'm a bit of a purist when it comes to installing UNIX style software. I prefer to install it via the package manager on the platform of choice (E.g. apt on Debian or Mac Ports on Mac OS X). However these repositories don't always contain the particular package you're after or may contain an outdated version.
+
+In situations like these where you end up building the package yourself I used to employ a system where I would install it into a subdirectory within my home directory. I did this because it doesn't overwrite a pre-existing system installed version, doesn't require root privileges and permits quick removal. To achieve this I just passed the --prefix option to the configure script before building. For example if I was building vala I might run the configure script as follows:
+
+./configure --prefix=$HOME/Local/vala+ +Following that with the typical
make, make install sees the package built and installed into that directory. The problem with this approach is that for every package you build you have to add the target directory to search paths such as: PATH, LD_LIBRARY_PATH, MANPATH, PKG_CONFIG_PATH. After a while this gets a bit unwieldy. This is where GNU Stow comes in.
+
+Stow manages these separate target directories by creating symlinks into the parent directories. For example to build vala I would pass a prefix of $HOME/Local/stow/vala to the configure script. After vala is built and installed, change to the $HOME/Local/stow directory and run stow vala. This results in symlinks to the files in $HOME/Local/stow/vala being created in $HOME/Local, with directory structure preserved. So if vala installs files to bin and lib these files will end up under $HOME/Local/bin and $HOME/Local/lib respectively.
+
+Stow can also delete the symlinks to support uninstalling. The end result is that you only need to add one extra directory to each of the search paths and custom software can be built, installed and uninstalled all without messing with the standard system and root privileges.

+For a while now I've had it in my mind to create a temperature logger. For no explainable reason I'm always curious about the temperature, particularly the extremes and strange fluctuations in one day. My idea is a basically to come up with a device that can read the inside and outside temperature and report these back to a host computer. The host would log the values in a database and make the current value and ideally the history available via a website.
+
+I finally got started on the project a couple of weeks back. I'm using an Arduino Nano as the bridge between the temperature sensors and the computer. Originally I was going to use (and actually purchased) the PIC based UBW but after seeing that the Arduino only cost a little more and had a full, freely available development tools for Mac OS X I switched to that.
+
+The temperature sensors are TI TMP275, 2-wire (SMBus) high accuracy digital temperature sensors. The largest package I could get them in was SOIC so I ordered some little adaptor PCBs from eBay. To solder them I also bought a fine soldering iron tip and solder paste from Jaycar.
+
+So far I have soldered the temperature sensors to their adaptor boards and got the Arduino up and running with an LCD. The next step is to wire in the sensors. When that's all working I'd like to use a simple RF transmitter/receiver pair to allow the outside sensor to be put on a separate device outside by itself and have its reading collected wirelessly.
+
+Some pictures of the build so far are below:

The iPad is the console of computers + -- mmustapic+ + +
The iPad announcement last week created a cacophony of commentary ranging from, "Meh, its just a big iPod touch", to, "Wow, we're witnessing the future of computing". On announcement day I was firmly in the former camp. There appeared to be nothing new aside from the larger screen and a custom Apple SoC inside.
+ +Since then I've read a lot of smart commentary on the iPad, which has swayed my opinion quite a bit.
+ +Rob Foster suggests its not the geeks that are excited about the iPad:
+ ++ +The darndest thing happened in the last five days and I was fortunate to be privy to it. Apple has gotten people excited about computing.
+ +But this time, it’s not nerds or geeks and certainly not IT industry analysts. It’s everyone else.
I'm a programmer, I write software both as a profession and a hobby. On my computer I frequently use compilers, interpreters, an IDE, advanced text editors, web servers, database servers and command line tools in addition to the more common web browsers, email client, music player, video player and chat client. The iPad feels weak to me because I clearly can't do a lot of those things on it. I am of course in a minority. For everyone else a computer that just works is all they ask. Your typical computer user shouldn't have to know about drivers, viruses, file permissions, software installers.
+ +Think of it as a video game console where you download the games. Now extend that thinking to all the applications. + -- John Debs+ +
I realized today that we think of the iPad as a computer, when it's really a console. No outcries about the Wii being closed + -- Cory Foy+ +
There's a class of computers that has been operating like Apple's mobile platform for decades: video game consoles. The model of computing that Apple is using for the iPad, iPhone and iPod touch is very similar to that of say Nintendo. Closed systems, software approval, single main task at a time, limited expandability, ease of use, hardware abstraction are all features of both consoles and Apple's mobile devices.
+ +Steven Frank and Fraser Speirs suggest we're entering the future of computing with the iPad and I now think they may be right. The iPad and its successors will make computing a bit less general but a lot more approachable for the typical consumer.
+ +All is not lost for us tinkerers though. Just like game consoles the iPad needs software too. And whilst the iPad is not self-hosting (yet) there's still a need for "real" computers and programmers to write the software.
+ +Alex Payne is wary of the future that iPad style computing may bring:
+ ++ +For now, though, I remain disturbed. The future of personal computing that the iPad shows us is both seductive and dystopian. It’s not a future I want to bring into my home.
He makes a good point. If every computer out there were an iPad style device, totally locked down and under the control of its parent company there would be little room for exploration. However that's never stopped people before, just look at the efforts of the iPhone jail-breaking teams or the ongoing efforts to conquer the Xbox 360. Not only that, there's the open source movement fuelled by a desire to make everything from hardware to software totally visible and free to modify.
+ +The products of open source projects don't have a great reputation for having a fine attention to detail or remarkable ease of use but they exist. And just by existing they ensure that there will always be things for the budding tinkerers out there to explore, modify, extend and learn from.
+ +Much attention has been made of the fact that its only possible to run one app at a time. Many people seem to attributing this to a limitation of the processor used in the iPad or the iPhone OS itself. Both of these are of course totally wrong. The iPad, along with the iPhone and iPod touch are quite capable of running more that one process at a time. In fact that's how email gets sent and received in the background and how your music keeps playing when you're in the Facebook app. Milind Alvares attempts to clear up some of these misconceptions in, Understanding Multi-tasking on the iPad: What is it really?.
+ +The iPad is promoting single focus computing. It does away with the memory requirements, power use, and task management that comes along with running more than one major app at a time. Just like hiding the underlying file layout simplifies things, so does this.
+ +As the iPhone has shown us, there's very little actual need for more than one app running at a time. As long as the experience of switching between apps is fast and state preserving it often doesn't really matter if an app is stopped and started or just switched to. There are of some widely cited exceptions to this though: Chat clients and third party music players.
+ +iPad doubters -- remember how iPhone didn't have COPY-PASTE for 2 years? Now compare THAT to multitasking! + -- Jevgeni Kabanov+ +
The inability to run a chat client or third party music player in the background right now does not mean that it won't be added in the future. I'm sure Apple is well aware of these use cases, just like it proved to be well aware of the need for copy-and-paste on the iPhone.
+ +There are solutions to both these problems that don't require full graphical apps to be run in parallel. The music player problem would be solved if the iPad SDK permitted a non-graphical background process to be left running. The OS could even impose strict limitations on the system resources that the process may use. In fact this is already possible in Mac OS X1, so given iPhone OS's pedigree may already be present.
+ +The chat client problem could be addressed in a similar fashion: A non-graphical background process with the added ability to send notifications. This is already possible with push notifications, however imagine they could be generated by the background app and perhaps also include standard user interface elements, much like third party apps in the Settings app. This way a new chat message could be displayed, with a field to allow a reply. Obviously these notifications would need to be less intrusive than they are now but it shows its possible.
+ +RT @mashable: Apple's iPad: Will it Improve the Web? (Cashmore/CNN)- http://bit.ly/d1UgWF flash, like IE6, must die + -- Jevgeni Kabanov+ +
From my geeky point of view Flash is a rash on the web and the quicker it just goes away the better. However I know there's a lot of people out there that are writing the iPad off due its lack of support for Flash. The thing is, if Apple sticks to its guns and doesn't include Flash on the iPad it can only help push the adoption of alternatives like the HTML5 canvas and video tags. Sure there's going to be some pain until that time but we'll all be better off at the end.
