    I just started gardening two years ago and it’s been so much fun. I’m trying to grow more food that my family eat, which are Vietnamese dishes. Being in California makes it a bit easier, although it could be cold for some of these tender plants. These are some vegetable plants eaten in popular Vietnamese…

  • Will WolframAlpha make the lazy lazier?

    WolframAlpha is launching right now. I just tried a few and see the cheat sheet. The interface is nice and the results were presented beautifully and logically. I’ll definitely use it for its designed purposes and Yahoo for the rest of search queries. If this type of computational search engine were widely available like it…

  • Understand a person from his/her blog comments

    What if there exists a system that goes out to all blogs, reads the comments, aggregates them into individual profiles. Each comment often has the name and website. A person shares her opinion at this blog, another one at another blog. Soon enough, you will be able to understand her thoughts. It’s a behavioral data…

  • Cache Control – Server vs. Client

    The server can set Cache-Control as far as it wants but if the client browser (Firefox, IE, etc.) says something else, the client rules. For example: an image with proper server’s Cache-control and Expires headers. If the client says “Cache-control: max-age=0” in its request, a conditional GET request will send and HTTP 304 code would…

  • Social networking

    Just playing with different social network (Facebook, LinkedIn) even I signed up for them a long time to see what I’ve been missing. And I see a reason for using them. Keeping connected with friends is definitely not new, by email, phone, meeting, etc. But it’s time consuming, especially with your larger network. This is…

  • Challenges in hiring

    Managing human resource is difficult, very difficult. I believe anyone runs a business would look at job hunting, resumes, cover letter, and everything about working for someone differently.

The newer Multi-Uploader needs to install into your computer and yet still provide a broken web interface (TRANSIENT_ERROR) and would not upload but keep trying (keep cycling through the process), I tried it in different browsers…
