This is quite a well-known thing among frequent and professional photographers, but still an interesting thing to know. I was also told that digital photo cameras can “see” in ultraviolet as well, but didn’t check if that’s true. As for infra-red light, this can be easily checked using any common “direct visibility” remote control. Most if not all use infra-red diodes to transmit signal. So I just pointed a remote at the camera, and made a shot. (Actually, camera real-time display also shows captured infra-red light, as it starts blinking in the remote.) Here is the proof of digital cameras ability to capture infra-red light. The bluish dot in the centre of the red-front-plastic-screen of the remote is infra-red light.
I decided to buy a digital companion to use while commuting, travelling for longer distances, creating voice memos, probably even listening to some FM.
Recently I was asked to measure the performance of my LG LM70 Express notebook (configuration 32HR or something like this). As I like small programs, I grabbed Super Pi and ran it:
This is not a review, but usage impressions. If you’re looking for LM70 reviews, try this one. It has good overall description, and is generally helpful. For general notebook considerations, see also my post.

Before going to vacations this summer (you may want to see the photos), I wanted to by a notebook, in order to be able to work a bit on my important projects while I’m away. Frankly speaking, I used my new and shiny notebook more for gaming, and not for work.
I was short of time, and had to make a fast decision on what notebook I wanted. My requirements were: lightweight (NOT 3 kg), WiFi, 15-inch display with resolution not lower than 1280×800, long battery life, discrete graphics solution, DVD-RW super-multi drive, and Centrino platform. I wanted all of this to be somewhere around 1000$. Read the rest of this entry »
Here I will list parameters you will most probably consider when bying a new notebook. I hope this post will help you choose what you really need.
Weight: ranges from under 2kg (1.6 for yet-fully-functional notebook) and up to 6 kg (DTR). Most of the notebooks you’ll encounter weigh around 2.5-3 kg. If you want less kilos – you’ll have to pay noticeable extra for portability.
Screen size: ranges from approx. 12″ up to 20″ (is that still a ‘notebook’ with 20″, how do you think?). The most common screen sizes are 14.1-15.4 inches. As for any other LCD display, the most important features are the reaction time (pixel on/off times), brightness and contrast. Usually you will not get those details in notebook specs; so you have to see for yourself. I just should note that cheaper notebooks (those in 600-800$ range) usually come with noticeably worse displays than more expensive laptops. Read the rest of this entry »
