This site was hacked

Thanks to hackers from around the world, this site was hacked and code was injected into the blogging system. Spams were sent from my server and I finally found the source of the problem.

As a result, this site was taken down and the blogging system was reinstalled from scratch with a couple of security measures to prevent the same hacks. Some external files (graphics, images, external scripts…etc.) are missing for the time being.

It’s all about solving problems

Having been a software designer and developer, what I’ve been doing is really just problem solving. For more than 2 decades, I’ve been solving problems for different clients on various types of projects – from live multimedia presentations, digital mixed media software, off-the-shelve games, computer-assisted learning, last-minute project rescue, enterprise apps, sales apps, educational apps, to native device apps… and more.

In the last couple of years, I’ve decided to spend more time on solving my own problems for my own projects. And it’s been even harder than solving problems for clients.

The main reason it’s harder is because I’m my worst critic. Or I’ve set my standard too high after solving problems for clients for so long. I want to do the best work – my own work, and most results are simply “not good enough”.

As I look at various apps on different app stores, I know I’m being too harsh on myself. But how do I solve this problem?

Addictive Games

I’m putting together a list of current and previous addictive games for mobile (iPhone, iPad, iPod Touch, Android, Nokia…), desktop, console or other devices.

What I mean by addictive is games that keep pulling the player back, games that keep players up for hours. Here is a quick list to start off with (I’m not including version or edition to keep things simpler):

  • Zynga Poker
  • A Monster Ate My Homework
  • Angry Birds
  • Bejeweled
  • Plants vs Zombies
  • Call of Duty
  • Halo
  • Myst
  • Pacman

Why am I putting together this list? First of all, I want to identify the ingredients of successful and addictive games. I’d also like to find out what people are interested in and why? And hopefully this would be a place where other game developers can find inspirations to create more addictive games.

Please add to the comments of games that you feel are truely addictive (max one self-promotion allowed if you think your game qualifies as addictive to other people). Thanks!

Welcome Visitors!

Thanks to the Visitor Map plugin, here’s a map of recent visitor locations:

What surprises me is there is not a single visitor from inside China (excluding Hong Kong and Macau). Is this an issue with the geolocation database or the plugin? Or the Great Firewall of China blocks my site?

If you’re from China, can you please leave a comment that you can reach this site?

Update: I uploaded the latest image, and there are two dots at approximately Shanghai and Tianjin or Beijing!

Screen sizes

From left to right: Dell 15.4″ XPS m1530, iMac 27″ quad-core, 13.3″ Macbook, Dell 24″ monitor (connected to the iMac as a second monitor).

The Macbook feels tiny. Using it for development outside of my office (e.g. at client’s office), especially when using Adobe suite, is frustrating. I often find myself swapping windows, opening and closing panels, and dragging things around. Spoiled by the new iMac screen resolution (2560×1440 + 1200×1920), compared to Macbook’s 1280×800 – that’s 5,990,400 total usable pixels vs. 1,024,000. However, my favorite screen is only at 480×320 – my iPhone 3GS (used to take this photo).

But these don’t come close to the life-size working iPhone costumes (YouTube video)!

Getting to the end of spams

After installing Vista on the laptop (XP had problem with some hardware device on this particular computer), I forgot to activate a email account that catches spams. After close to one and a half month, I got notification from the email server that this account was full. Checking the account revealed 5586 email stuck on the server. It took all night and morning to clear them up.

Crazy weekend of spam

Never had I experienced spoofed email bounce like I did this past weekend. It started on Friday evening, and I received about 7000 bounced email that were spoofed using my quantumwave.com domain.

The problem was, the hosting company did not have SPF (Sender Policy Framework) set up, and I had a catch-all email account that accepted *@quantumwave.com. All the spoofed email were sent using some random account names selling illegitimate software or other goods.

I contacted the hosting company and they suggested that I turn off my catch-all email account and activate SPF on the email server.

One little problem with the catch-all account: Whenever I register email at a website, I usually use their domain name as my email account (e.g. at somecompany.com I’d use somecompany@quantumwave.com as my registration email). This made it easy for me to filter email, track the source of spam and know which company distributes email to third parties (I was surprised by a few big name corporations doing that).

Anyhow, before I could terminate the catch-all account, I had to set up all previously known email aliases I registered at every website I used. The last count is 330 aliases; so it took some time to track all those down and add them to the server. After that was done, I terminated the catch-all account and it was back to normal.

I’m sure I’ve missed some email aliases and those accounts will no longer work (senders will get notification that those email accounts do not exist). A rough estimate of the time I spent on this madness is approximately 5 hours (racing with/deleting incoming email, adding aliases, setting up server-side filters).

One important piece of information I learned: Activate SPF on the email server.

FITC, IdN and newspaper interview

To those who are attending this year’s FITC festival, take a look at the IdN booth and the Two Faced exhibition. I wrote some articles for IdN many years ago (in 1993, when it was called MdN – Macintosh Designers Network), and interviewed the President & CEO of Macromedia (Bud Colligan) back then. IdN is very popular in Australia, U.S., Europe and Asia. It’s about time Canada finds out more about this designer magazine and their other publications.

For those who read (traditional) Chinese, here is the Sing Tao newspaper interview of me (楊光) at FITC (click to view full size at Flickr). They asked about my experience, work, this year’s presentation and the festival. I was a bit surprised they used almost 1/3 of the page on this article.

Newspaper article of me at FITC

My presentation is on tomorrow (Tuesday) at 2:45pm. It’s on Flash Lite and mobile development. I invited Dongyub Lee from Seoul to join me to talk about some of his projects on device UI and games development.

Thanks to Shawn Pucknell and the FITC team for another great festival.
