Bed Office

with 3 comments

When ever I am working from home, I would be working mostly from bed,
holding the laptop with left hand while right hand types. That certainly is poor ergonomics and bad for both my wrists and my coding speed.

Searched local stores for any furniture suitable for fixing or holding the laptop on bed. Couldn’t find any. So decided to build one for myself.

Necessity is the mother of invention. Initially thought, I can cut and nail wooden planks together, and went hunting for wooden strips to a nearby hardware shop. I surveyed the whole shop looking items that could be helpful. Whoa! found more than what I expected – plastic PVC plumbing material! There were pipes of various lengths, joints and more… Bought 1/2″ diameter PVC pipe and 4 joints – two 130 degree, and one 90 degree corner piece, all for under 5 American dollars. This is so much better and easy than cutting wood with hack-saws and trying to nail it!

I picked the parts I wanted (see the design above) and assembled the frame on the shop floor. The old salesman was looking at this weird plumber with confusion.
I now had a lightweight solid frame that was strong and stable enough to support the laptop, but it wasn’t finished. I needed some way to hang the laptop to the frame so that it is held firm. I bought a L cross-section plastic strip and tried clamping it to the pipes, but wasn’t strong enough to hold the laptop. Thought of getting treadmill book holders, but couldn’t find them in any nearby shops.

Corrugated cardboard is another strong material. I stapled one across the central pipe and pasted a supporting strip towards the bottom end of the corrugated sheet. Thats it! My Ferrari laptop is now firmly held between the angle of the corrugated sheet. It forms a triangle – triangles are the strongest polygons. Much of its weight is transmitted by the frame. My stomach which used to take much of the weight is more free. Both my hands are free! What more, my laptop bed holder with its creamy white PVC pipes looks like a space age instrument!

At JavaONE

leave a comment »

I stopped by JavaONE Moscone Center, this evening, it was quite crowded. Java Pavilion was bustling with companies and groups showcasing some of the amazing stuff with Java. John and team won Duke’s choice award for model rail road. There was a java GUI app that reflected the state of the track. You could change tracks by clicking on the track in the GUI.
My mischievous mind changed tracks when the train was half way through a junction, causing the train to get stuck in the middle!

Another really cool stall was the Looking Glass 3D desktop operated by hand gestures (just like in movie Minority report). You could wave away a window or maximize it by pulling it towards you. (see the new videos from Cebit on lg3d site)

Security Sun Alert Feed

leave a comment »

Sun publishes Sun Alerts to warn users about product issues. A Security Sun Alert is published for every security vulnerability found in supported Sun products.

You can subscribe to a weekly summary email of all Sun Alerts. Hoping that an RSS feed is one way to propagate the news on the net, I wrote a small web-scarping script that looks at the SunSolve Sun Alerts page on an hourly basis, and posts a summary of all recently published or updated Security Sun Alerts to the Sun security blog (http://blogs.sun.com/security)

Apart from Sun Alerts you may also find notes about product security issues (like the AMD64 FPU issue, to which Linux and BSD were vulnerable, but not Solaris!)

See also alertpool which is aggregating security alerts from major vendors and sites.
