Survey: Context-Aware Applications in Mobile Devices

Imagine you have a mobile device, like a PDA or a smartphone, that knows where you are and understands the context of the surroundings (e.g. “I’m at home” or “I’m at work” or “I’m at the mall”). Now, having such a device, what kind of things do you imagine the mobile device would do to make your life easier and/or better?

I’ll give you an example to get you started. For example, I would imagine that when I arrive at home or at work, the mobile device would wirelessly and automatically synchronize with my home or work computer without my intervention. It would also inform me if it had found a new Wi-Fi network (maybe the neighbour had just installed it). When I’m walking in the mall, for example, it would detect if there were any wireless network or other services that I could use during my visit at the mall, for example a mall shops directory, free internet access, movie schedules, ordering food from the food court, paying for parking, etc.

I would really appreciate it if you could write your ideas as comments to this post, and you could write in English (preferred) or Indonesian if you’d like. Thanks!

Bruce Schneier Interview

There is an audio recording and transcript of a very good recent interview with Bruce Schneier, the father of cryptography and a well-known security expert, mostly about recent security issues, biometrics, and his latest book, Beyond Fear.

Host Doug Kaye says, “This is the one interview I hope everyone will hear.”

In his lated book, Beyond Fear, security guru Bruce Schneier goes beyond cryptography and network security to challenge our post-9/11 national security practices. Here are some teasers:

  • “We’re seeing so much nonsense after 9/11, and so many people are saying things about security, about terrorism that just makes no sense.”
  • “Homeland security measures are an enormous waste of money.”
  • “If the goal of security is to protect against yesterday’s attacks, we’re really good at it.”
  • “The system didn’t fail in the way the designers expected.”
  • “Attackers exploit the rarity of failures.”
  • “More people are killed every year by pigs than by sharks, which shows you how good we are at evaluating risk.”
  • “Did you ever wonder why tweezers were confiscated at security checkpoints, but matches and cigarette lighters–actual combustible materials–were not?…If the tweezers lobby had more power, I’m sure they would have been allowed on board as well.”
  • “When the U.S. Government says that security against terrorism is worth curtailing individual civil liberties, it’s because the cost of that decision is not borne by those making it.”
  • “…people make bad security trade-offs when they’re scared.”

Read or listen to this terrific interview in which Bruce also says what he thinks of the 9/11 hearings and answers questions from listeners regarding spam and biometrics. This is one of our best.

Hurricane’s Grill: A Review and More

Hurricane's Grill Logo

My close friends in Sydney treated me a nice birthday dinner at Hurricane’s Grill, Bondi Beach. My initial expectations were high due to various comments given by my friends regarding this restaurant. It turned out that the food and service was, overall, excellent. I had the “Ribs and Steak” which consists of a half-rack of grilled pork ribs and a 200gr steak. I also ordered creamy mushroom sauce, which was very rich and creamy, I think everyone liked it. I had been warned about the generous portions served at Hurricane’s, but I can usually eat a lot. I was given a choice of pork or lamb, but I was not in the mood for lamb. I was a little bit disappointed with the steak though, it was nice, but together with the ribs it’s like comparing driving a 1995 Toyota Corolla (which was a good car when I had it) and driving my friend Fernando’s Toyota MR2 Spyder. I wish I had ordered the Portuguese chicken instead of the steak, the chicken was full of flavour and tender. The ribs was the best ribs I’ve ever had, better than Tony Roma’s. We also ordered ceasar salad and onion rings which were not bad, but not really that special in my opinion. I had a Crown Lager to wash off the delicious pork ribs. The price tag is a little bit too expensive for a student like myself, but at a “mere” AU$35 for a huge and delicious portion of ribs and steak and a quality beer, it is a bargain for most working Australians. Plus, there’s a beautiful beach right across the road.

An interesting thing I found when I was looking for the restaurant’s website to put in this post is that Hurricane’s Grill is an EPSON Australia customer. One of the top results in Google led me to a PDF document in EPSON Australia’s website describing the system that the restaurant had commissioned from EPSON Australia to be used for POS, kitchen order and receipt printing. The restaurant waiters also use handheld devices to take orders from the patrons, which I presume are linked via a wireless network to the kitchen’s ordering system. The restaurant’s main objective for having the system was to minimise the time from taking orders to serving the orders to the tables. I have seen this kind of system being used in a Wagamama restaurant when I was in London around July 2003, so it’s not a new concept to me. But it’s still an intriguing idea for a business opportunity. :D

Things I Learned Today

  1. I finally read this article (which had been sitting for a long time in my thick pile of printed “read-later” articles) from Apple Developer Connection about XMLHttpRequest which plays a major part in AJAX, which has been discussed a lot lately in the web development area and is used by popular services such as Gmail, Google Maps, Google Suggest and many more.

  2. Maybe I should have named this category “Things I Learned Yesterday” since I usually post after midnight.

  3. There are still a lot of people who are so naive and believe everything they got from the Internet or from forwarded emails, especially urban-legend or scarelore kind of stories. I hate those.

  4. CeBIT Australia exists and it will be held from 24 to 26 May 2005 at Sydney Exhibition Centre in Darling Harbour. I’ll be there if I don’t have any exams or anything like that during that time. Free online registration.

  5. Need to put less ginger and more salted fish for my spicy eggplant with minced pork.

  6. A second look on iSCSI and iSCSI on Linux, and a first introduction to Vinum Volume Manager after reading a Slashdot post about Firewire storage.

  7. There are several available options for backup solutions that are POSIX ACL aware, including using star, proper backup program like Arkeia, patched NFS (out-of-the-box with SuSE), rsync with ACL patch, etc. Info from this post, googled after answering a mailing list post.

  8. “IT Research Methods” is such a boring and useless (at least for me) subject. It’s hard to force myself to do the assignments for this subject. I wouldn’t have taken the subject if it weren’t mandatory. Oh, what the hell, might as well make something useful out of it since I’ve already paid for it.

  9. Evolution 2.0.x doesn’t provide an alarm for contact items such as for contact birthdays and anniversaries. I haven’t looked at the source code yet so I don’t know how hard it is to implement this. It’s surprising since I thought many people would have wanted this useful feature.

Things I Learned Today

  1. SMART hard disk monitoring, emerged smartmontools, and set smartd to run in the background. (Via Slashdot)

  2. The Vigenère Cipher, I knew this from my cryptography class so it’s just refreshing my memory. (Via blogwalking to Mr. GBT)

  3. Next time, put more breadcrumbs for the stuffing. (Via cooking roast turkey)

  4. X.org X11 transparency and shadowing is still not stable, e.g. glxgears caused X to crash even with AllowGLXWithComposite enabled. (Via Gentoo Wiki)

  5. AUD 1 = IDR 7,500++, and rising. (Via Yahoo! Finance)

  6. There’s a Japanese pr0n model/actor named Anna Ohura, not to be confused with Anne Ahira. (Via a dream I had the other night. As if I’d tell you.)

  7. A soda can and chocolate can be used to make fire. (Via Boing Boing)

  8. The notorious TBE managed to screw up my Firefox, again, after an upgrade. I had to make a backup of my Firefox profile, delete the extensions directory and reinstall all of my Firefox extensions. It was strange that after I reinstall TBE it was working fine again. So I stuck with it, for now… but one of these days…

  9. I finally know what Podcasting is about. I’ve heard about it for so long but I couldn’t be bothered to look it up in Wikipedia or Google until this morning. (Via blogwalking to Priyadi)

  10. There’s a Wiki clone written in Ruby called Instiki that seems to be recommended by some people. Not in portage yet, so I haven’t bothered trying. (Via Nat)
