The crossroads of life and tech

Why (and How) to Unshare Your iTunes Library

When I checked into the hotel tonight, I fired up my macbook on the provided (hardwired! gah!) Internet connection and went about my evening routine (blogs, pocasts, email, twitter… you know the deal).  When I popped open my iTunes to crank on some tunes something came to my attention:  There was a remote library showing in my iTunes.

At first, I gave “John’s Music” very little thought, I was listening to a podcast at the moment and wasn’t interested in investigating.  However soon after, when the show ended, my curiosity got the better of me and I went for a peek.  The music itself wasn’t all that amazing, but upon closer inspection I noticed something else.  I realized that I now knew far more about John than I thought I would and just from looking at iTunes.

Based on primarily his playlist names, and to a lesser degree the content, I was able to deduce:

  • John’s last name
  • John’s wife’s name
  • John has two daughters
  • John’s daughters’ names
  • John owns an iPhone
  • John’s wife owns an iPhone
  • John is from the US
  • John’s daughter (presumably the eldest) has an iPod Shuffle
  • John is highly spiritual and a Christian

Those are some pretty crazy personal details… and they were all there for the taking right out of a publicly shared iTunes folder.

How do I Un-Share?

It’s actually ridiculously easy…

First, go to your iTunes Preference Panel… Second, unselect the “Share my library on my local network” checkbox.

Now I realize that this may seem a drastic step for those who only ever use their iTunes at home.  But if you travel, or make use of open public wi-fi hotspots (or poached ones) your iTunes library could be giving away personal information without you even knowing it.  It also illistrates the point that not all Apple products ship in a “secure” mode as often touted.  It’s not out-of-the-box functionality, but it isn’t difficult to poach files out of someone’s iTunes folder if they’re DRM free…

DIY Render Farm – 186GigaFlops

I did this post up on the GGP blog a few minutes ago, but I wanted to pass it along to everyone here too in case (gasp!) you’re not a GGP subscriber [rss].  A guy put together a six-node render farm using nothing but raw components and a special diy case using… wait for it… wait for it… an Ikea cabinet.

This thing is a beast.  24 CPU Cores and 48GB of memory sure beats the hell out of the server I was planning to put in my basement.  I ran the numbers on the components he used and it looks like it would cost about C$6500.00.  Of that the funky Ikea case is less than 1% of the total.  Pretty spanky!  :)

CityTV Breaches Creative Commons

This week CityTV was cited by the Canadian Broadcast Standards Council for failing to uphold the copyright of a man who published photos on Flickr under a Creative Commons license.  Though the ruling doesn’t actually compel CityTV to atone for their actions by crediting the photographer (Joel Charlebois, aka uwajedi).

When CityTV arrived on the scene to do a story about the burglary, Charlebois says that he “refused [a reporter's] request for an interview….[and] asked him to leave.” Charlebois did, however, say that he “had taken pictures of the perpetrator and was looking forward to posting them on [his] Flickr site”; the reporter “was interested in seeing them,” so Charlebois gave him his card, but, he says, not permission to use the shots in any way. [torontoist]

The photos are of a man who allegedly tried to break into the photographer’s home.  After posting the Creative Commons licensed photos to a couple of groups on Flickr, they were run by CityTV on their newscast without providing any attribution despite the fact that they were aware the Charlebois had taken the photos.

It took nearly nine months for the CBSC to make its ruling.  In my opinion, the fact that it doesn’t actually compel CityTV to fix their mistake but merely acknowledge it fails to uphold the spirit of the CC license.  As Duane Storey observed:

If I were to use CityTV footage on my blog without attribution, I would bet I would get a nice cease and desist letter forcing me to take it down in no time. That they think the laws should be different in each direction seems characteristic of most large media conglomerates these days. [duanestorey.com]

This sentiment seems to be shared by a number of individuals including Charlebois himself.  Must it be up to independent media such as bloggers and podcasters to show the “professionals” how to properly attribute work?  Was this simply a case of laziness on CityTV’s part or is it a symptom of a deeper disdain for those who don’t actually get to carry a press credential?

Mac Lab Rat – GGP #084 :: We Have Chunks

This week’s episode of the GGP was so jam-packed with geeky goodness, Dave had to split the show into two chunks.  You can find both Chunk A and Chunk B on the GGP blog.

To help keep the show length reasonable, the Mac Lab report for this show is a quick one.  The inspiration comes from a post by Tim Cox over at MacApper.  This is a collection of Automator scripts which will help to keep your downloads directory clean.

These scripts provide methods for managing your Internet downloads for everything from music files (Tunes to Trash), disk images (Perfect Dismount) and zip archives (The Zipper).

Overall the tools do a decent job of keeping things tidy and are a great example of a practical use for Automator for the everyday user.

Vancouver Apple Store Opening May 24th – 10:00am

This Saturday marks a major milestone for the city of Vancouver.  Well, perhaps not for the city, but definitely for the mac-geeks in the region.  This Saturday is the long-awaited opening of an Apple store west of Toronto.

I’m not the only excited local blogger.  See some posts today from DuaneStory and Miss604 (via the twittersphere of course).

The Apple Store announcement on the Apple website provides all the necessary details for the grand opening and even provides links to start booking your “genius bar” appointments.  Time to get my MacBook case fixed again, the timing is wonderful.

A Geek’s Tour of Boston & Cambridge

On my recent trip to Boston I had a day all to myself thanks to my lovely wife being stuck in a conference (which was the catalyst for the trip in the first place).  I took the opportunity to do a bit of a Geek’s Tour of the area, some of which I’ve already blogged about.

Macbook on BenchThe day started off in the hotel room poaching free wi-fii off a local hospital.  It’s damn decent of them to offer a wi-fi hotspot free to patients and their families (and geeks who are willing to sit at an odd angle near the hotel window).  I was completing a draft of an email that I was planning to send to the mayors of Burnaby and Vancouver on the topic of municipally supported wi-fi.  The email got written up, I checked the twitter feeds (fired off a tweet or two I think) and then headed to my first destination.

I hopped on the “T” as they call it in Boston and took the Green line all into the heart of the city and Government Center.  This is the central government complex and one end of the area served by Boston’s open wi-fi pilot that they’re conducting with ISP Galaxy Internet.  I headed across the street to the Faneuil marketplace and parked myself on a bench.  I wasn’t gonna hang around very long because it was bloody cold and windy, but I stuck it out long enough to fire off the email and quickly blog the experience.  As much as I was enjoying the free signal and 5-bar signal strength (over 90%) it was time for me to g as there were three more stops on this tour and it was already approaching 11:00am.

I re-boarded the “T” and headed out towards Cambridge.  My first stop was the MIT museum.  I got off the train and walked through the streets of Cambridge past several campus buildings.  The architecture on some was quite unique, and there were a great deal fewer old buildings in and around the area.  Much of it appeared to be mid-20th century construction or newer.  The walk from the “T” station to the museum was longer than I had anticipated but provided me a look at a side of Cambridge I wouldn’t have otherwise had the chance to see.

When I arrived at the museum the first thing that struck me was the austere, spartan look of the main floor.  It was very functionally laid out, with lots of “white space”.  The most interesting exhibit on the main floor was that of the CityCar.  This is a project being proposed by MIT professors and graduate students to create a pool of electrically powered cars for use in urban settings, much the same way bicycle pools exist in major European cities today.

On the upper floor was an extensive robotics exhibit and though much of the material was dated (mid-late 1990s) it gave great insight into the directions of artificial intelligence research and robotics.  I got a chance to see the original “Kismet” robot which was neat after having seen so many Discovery channel programs about it.  There was also some DNA and genetics research on display, and through I read and was able to understand the words, much of the significance escaped me this time around.

After MIT’s museum, I re-boarded the “T” and headed for Harvard Square.  Once I arrived, the only thing I could contemplate was lunch, it was nearly 2:00pm after all,  On the recommendation of Miss604 via the Twtittersphere I was able to find a great place for a pint and a quick meal.  I stopped in at John Harvard’s Brew House.  The atmosphere was a bit dead in the lull between lunchtime and happy hour, but I was able to get my geek on by getting some writing done on the Technological Dependence post, and it was in fact my lack of a paper map and an attempt to Google-search my way to directions (instead of asking for directions or a map) which inspired that post.  (Sidenote: I did eventually FAIL with the digital maps and find my way to one of the paper variety.)  The food was pretty good.  I followed the aforementioned recommendation and tried out the Meatloaf (in sandwich form at lunchtime) and with it a pint of the Sam Adams Nut-brown ale (they were out of the porter).  I don’t know if there’s enough for a Ho Yummy.com review but it was certainly a decent pub lunch.

After lunch was the final stop for the afternoon, a trip to the Harvard Museum of Natural History, and the Peabody Museum.  This was geekery of a different kind.  I’ve always been a fan of history, and this gave me a chance to explore some great exhibits on geology, archaeology and to a lesser degree, palaeontology.  There wasn’t a whole lot to differentiate this museum from other similar ones I’ve visited in the past.  In fact it was relatively small when compared to the Field museum in Chicago or even the Royal BC Museum in Victoria; however for a school museum it was very well maintained and they allowed flash photography.

All in all it was a very enjoyable day.  I took a few dozen shots, some of which I’ve featured here, the rest of which are in the Flickr set for the trip.  If you’re ever in Boston, take a day trip out to Cambridge and check out the sights.  They’re wonderful cities, full of history, and a great place for a little geeky adventure.

Changing an iPod Mini Battery

Recently I had the experience of changing the battery on a [second-generation iPod mini -- link it somewhere].  This isn’t a difficult task in and of itself and though it may scratch the unit is something which can give you a renewed music-listening experience for a fraction of the cost of getting a “professional” to do it.

DISCLAIMER: As with all of its brethren, the iPod mini does not ship with a “user-servicable” battery (or anything else for that matter).  This means that if you run into any trouble with the unit, you need to take it to an Apple-authorized service centre.  Opening the unit yourself WILL void the warranty.  Unless of course your warranty has already run out, in which case: fill yer boots!

Alright, with that out of the way, on to the deed at hand.

As my guide to the process I used this guide from CNET.  It was extremely helpful and provides detailed instructions as well as a tour of the inside of your mini.  For that reason I’ll link to their guide and only provide a “Coles notes” version here. (For those of you outside Canada, Coles is a book supplier that produces a guide series similar to Cliffs Notes.)

Step 1 – Get yourself a replacement battery Chances are when you get the new battery it will ship with some sort of tool.  For this process you need a flat screwdriver (primarily for use as a pry-bar), and a small [Phillips screwdriver -- wiki].  If you have a small jewellers set you can use that, though you may suffer some minor damage to the flat-head if it’s not very strong.

Step 2 – Remove the covers Use the flat-head screwdriver to pry off the top and bottom covers.  Keep in mind that the lock switch will come off with the top cover.  Both covers were originally secured with glue, so place them sticky-side up to not mess with it too much.

Step 3 – Remove the bottom spring-plate Use the flat-head screwdriver again to remove the spring-plate from the bottom side.  This is holding the unit in place.

Step 4 – Remove the screws Using the small Phillips screwdriver remove all the small screws. I realize I shouldn’t have to tell you this, but DON’T LOSE THEM!.  You will need them later.

Step 5 – Remove the command-interface jumper If you look at the bottom of the unit, you’ll see a small plastic connector on one side.  Carefully remove this (this is the interface to the command buttons on the front of the casing).  Once it is removed, the guts of the iPod should be unencumbered.  Slide the whole unit out the top.

Step 6 – Replace the battery The battery will be stuck to the unit with a small piece of adhesive which is sticking it to one of the chips on the iPod’s mainboard.  Slowly peel off the battery and hold it perpendicular to the board.  Take note of the placement of the different coloured wires then remove the jumper.  Place the new battery on the device and reverse the process, taking special care to ensure the wires are on the correct pins.  This is pretty much the easiest part of the whole process.

Step 7 – Charge and Test (technically optional) I highly recommend doing a full charge-and-test while the unit is disassembled.  This will ensure that if anything isn’t hooked up correctly, it can be corrected without having to re-dissecting the iPod.

Step 8 – Re-assemble Follow Steps five through one to re-assemble that mini.  Take care to smooth out the top and bottom casings, and to place them back sticky side down.  That’s all she wrote.

Overall the experience for me went pretty well.  The article CNET article was very helpful in getting this completed quickly and with a minimum of fuss.  Admittedly I didn’t read through the whole article, and had a touch of difficulty as a result.  Follow Step 7… for the love of God.

Once I got the unit reassembled, it ran into exactly the same problem as with the original unit.  It didn’t want to retain a charge.  Since the new battery was still, well, new I decided to swap in the original again to make sure its behaviour hand not changed.  They were both the same.  This leads be to believe that there are is a problem with the charging circuit and not with the battery.  Oh well… win some and lose some I guess.

Technological Dependence

At what point did I become completely dependent on my technology?  I mean, I can remember a time when I didn’t carry  a cell phone.  Sure my life was simpler back then, but even doing some simple tasks today seems all to difficult without the phone.

Photo Credit: Marcin Wichary on FlickrAs these devices have made their way into our lives, the concept of convergence has helped them stick.  Two hundred years ago, the only way to communicate with someone was either in person, or by post.  Then came the invention of the telegraph.  This would allow someone to send a text-message to someone in another city by way of an electrical current.  Really, this was the predecessor to email, fax and text messaging.

Seventy years later, Alexander Graham Bell was busy working on a device to help his wife hear, and in the process managed to invent the telephone.  Imagine, being able to have a conversation with someone across the country much the way you would if they were sitting in the next room.  Before long these technologies began to make their way into every home in the Western world.  You could contact anyone, at home or at their place of business and speak to them directly.  The information age was upon us.

By the time I made my way on the scene in the early 1980s phones were commonplace, analog phones were beginning to give way to faster and higher-capacity digital phone systems.  With these came the advent of the modem — a device solely designed to translate analog telephone signals into digital signals for processing by a computer.  The age of the Internet was beginning.

This brings me to the 1990s and the start of my serious involvement with technology.  I was fascinated by the ability of computers to connect and talk to each other pretty early on.  Being able to exchange files with my friends via the local BBS was quite amazing to me at first, but soon became a primary method of communication (even if it did take an hour to download a file over ZMODEM on my 2400 baud modem!) for passing geekery, photos and games back and forth with a few friends who “got it” early on.

As technology continued to improve, so did my Internet experience.  We soon upgraded to a 56k modem which allowed us to download more than 20 times faster.  I could download the new 1.2MB Wolfenstein Demo (which wasn’t really new) in only several minutes.  But this really was only beginning, because a few short years later came ADSL.  This may have been the beginning of my technological dependence.

Photo Credit: rebelniko on FlickrAs things were progressing on the home Internet side of things, things were also progressing with my own personal communications.  By the mid-1990s (sometime between 56k and ADSL) I managed to convince my parents to buy me a cell phone.  A communications device of my very own.  We had tried to convince our parents to get us a second phone line, just for the kids.  Something they begrudgingly did as the Internet became more popular because, well, they couldn’t get or make a phone call after we came home in the evening.  But back to the cell phone, my first phone was what I liked to call the Motorola “Brick”.  I don’t know the exact model for it.  This phone lasted me for about three years and quickly became my constant companion.   This may also have been the beginning of my technological dependence.

When I speak of my technological dependence, I do so in the context of activities that I used to be able to do unassisted, but which now seem to require some sort of technological intervention.  Let me provide an example.  When I go to a large event, or even a shopping mall with friends or my family, often times we’ll split up and explore individual activities.  If one of us has forgotten their cell phone, or has managed to run out of batteries this tends to propose a rather large problem: how will we meet up later if I can’t call Jimmy on his cell phone?  In these instances I’m reminded that I haven’t always had a cell phone, and at some point in the past nobody did.  How did they manage to co-ordinate their activities?  Pre-arrange a meeting time with friends?  Wow.  What a concept.

In other cases the technological dependence has taken the shape of changes in the fundamental ways that we conduct certain activities.  For this example, I’ll employ an experience from a recent trip to the airport.  When checking in at the airport the airlines now have a vastly reduced number of check-in agents.  Why?  Because all they need to do now is check your bags and place a sticker on them.  Your boarding pass?  You deal with that at a computer terminal before you queue up.  Not handy with computers?  Well, you’ll just have to figure it out for yourself.  The process is entirely computerized.  Add to this that all the security equipment is powered by computers and you’ve got a pretty technology dependent industry.  Never mind a power failure.  If there were to be a major failure in an airport’s computer network (border router failure, cable cut) it would put the entire airport out of commission until it was fixed.

Photo Credit: AlexMuse on FlickrIn still other cases our dependence shows in our inability to follow the guidelines that technology gurus have been spouting for years.  The one that comes foremost to my mind is that of “Backup! Backup! Backup!”  The majority of people who use computers on a daily basis don’t back up their data regularly, if at all.  I’ve been guilty of this myself on occasion, and have been remarkably fortunate with relatively few disastrous events though I’m far from immune to the data-loss syndrome.  Our lack of ability to simply copy and paste data into another location is astounding.  As with most things in life it’s the people who’ve had the most dire failures who tend to be the advocates for helping people to avoid future catastrophes, so considering their wealth of knowledge, why don’t we listen?

Now despite my deliberately negative slant on the first two examples of technological dependence, the news isn’t all bad.  Technological dependence is simply and indication of how society has developed technologies which are so useful that they’ve permeated the daily lives of billions of people around the globe.  What we need to do as a collective in the years and decades to come is to develop methods to keep the technology we use sustainable and mitigate failures of the technology so that only the most disastrous events could ever disrupt the service.  Some of these solutions will be high-tech solutions that will require investment in infrastructure or new product development.

For the airport example, and admittedly this is something that is probably already done to some degree, ensure that there are multiple points where a network connects to the outside world.  By ensuring that network infrastructure is made redundant and is kept as physically separate as possible, the airport can continue to operate with little or no time spent with systems being offline.  The same would apply for connections to the power grid.  Though simple in concept, a solution like this is relatively complex compared to those for some of the other problems I presented.

Photo Credit: Kevin on FlickrThe backup problem represents trying to a fundamental behaviour in people: we’re lazy.  The only backup solutions that tend to work very effectively are those which are automated and which we don’t have to think about unless disaster strikes and we need to recover our data.  To solve this problem there are a few possibilities.  Backup services which with only a few clicks of the mouse we can connect to and have them store our data.  Easy enough for most people, and as long as you’re happy with your information sitting on some company’s servers this is a viable solution.  The second (and admittedly more complex solution) is to back up everything to an external hard drive and store that in another location.  This requires planning, forethought and at the very least a spare drawer in the desk in your office to store the drive offsite.  This also requires more up-front investment than the previous example, but doesn’t have any ongoing monthly charges.  In both cases the backup can be relatively automated and off your mind.

Let’s not forget about that pesky dead cellphone problem either.  There is one really easy solution for this one too.  Plan ahead.  Try it sometime, all the cool kids are doing it.  By agreeing on a predetermined time and place to meet up, you can avoid those nasty “Where’s Jimmy??” scenarios and save on precious cellphone minutes to boot!  Now if anyone raises their hand and says that “but I use my cell phone to tell time?  I can’t check the time if I don’t have my phone!” — I have two solutions for you, ask someone or build a sundial.  Oh wait; you probably need the internet access from your phone to get the sundial instructions off Google… scratch that.  The second solution is to bring your iPod.

Emailing the Mayors from Boston’s Free Wi-Fi

As I promised in last night’s post, I’m using Boston’s free Wi-Fi network to drop a quick email to the Mayors of both Burnaby and Vancouver.  The gist: Free Wi-Fi in urban centres is a great thing.  I decided to include a copy of the email on the blog for anyone who might be interested.

Good morning Your Worships, I’m writing this letter to you from the city of Boston where I’m currently on vacation.  The subject of this letter is also the service which is allowing me to send it; Boston’s first open-Wi-Fi project.  The city has partnered with local companies to provide free Wi-Fi access to residents and visitors of the city’s Faneuil Marketplace. I would like to promote the idea of starting up a open Wi-Fi project in the Lower Mainland.  With the pending influx of international visitors to the region, providing an easy way for them to stay connected to their families and report back on their adventures in BC would cast a brilliant light on our ability to embrace new technologies and the region’s vision for the future. While covering the entire region in time for the Olympics is hardly a feasible option, placing the free access in some key locations around the region could be both cost-effective, and provide basic access to a large number of people. A couple of examples would be: - Key Olympic Venues (GM Place, Skating Ovals etc.) - Library Square, Vancouver - Robson Square, Vancouver - Pacific Center, Vancouver - Metrotown, Burnaby - Deer Lake Park, Burnaby I know there was talk about placing Wi-Fi access points in Vancouver a few years ago, in fact I believe it was mentioned on Mayor Sullivan’s blog.  With the  coming international attention on the city, I feel this would be an excellent opportunity to showcase the region’s growing technology sector and to make the Olympic and Paralympic games that much more accessible to the world. Thank you, Keith Murray

That’s it!  I’ll let everyone know if I hear back from either Mayor.  It’s really windy, and I’ve chosen an outdoor location.  Time to run!
