The difference between Google and Yahoo.

Recently I started to think to switch to from Google to Yahoo.

Help to select projector for Home Cinema.

There are different ways to display entertainment content (movies, concerts, games, etc.) and build own “Home Theater”. As I’m strongly against cable/broadcast television, regular TV-set is not included into my wish-list. Projector is right solution for me (I do not say that it is not possible to get broadcast TV with projector, but it is more tricky than with regular TV-Set). Influenced by last day events I’m considering to get projector for home, that will satisfy my requirements.

So, I’m browsing and digging Internet for different reviews, suggestions and advices for home projectors. There are enough interesting and valuable information, however I want to share with one great resource, where I found a lot of useful information.

It is , it is great that seller is trying to educate customers as much as possible. I found a lot of information,

– of course, you can find different projectors to purchase, additionally there is extensive information and specification given, projector models are sorted.

– Web page strongest part is description about projects different functions and features theory, like description for brightness, contrast, resolutions, the difference between LCD and LDP, and much more.

– Nice tool for projector selection, that allows to select project for side to side comparison.

– Simple calculators for brightness and appropriate value of lumens for projector, !!! screen size calculator tool.

– Lamps! It is well known fact, that projector lamps are not able to function for ages, so buying projector you need to be aware of the lamp price (that is 1/3 or even higher), most likely that sometimes you will need to change the lamp. So you may use this tool, where you select manufacturer and enter model of the projector, as the result you get required lamp and price.

Great Job and personal gratitude for huge work!

Uncounted reason to switch…

Well, it is iLife08. There are few programs go with it. Some of them are really for specific cases.

For example iMovie is extremely handy, when you need to edit and finalize filmed episodes by private-camera. GarageBand to create music in the interactive way.

But today’s topic is not about these nice programs, today about iPhoto 08. Cheap ‘point and shoot’, not cheap ‘point and shoot’, professional cameras, almost everyone has camera and takes photos (isn’t it ? ).

So sooner or later there is requirement to manage photos, iPhoto is one of the easiest way to get things done (that I’ve seen).

One more reason to consider switch to MAC OS.

 Do you have to create any presentation on work, university, volunteer activity ?

The answer to the topic you have to try “d**n f****g” great software called ‘Keynote’ from the set iWork 08. It is software for creating presentations, PowerPoint is analog.

iWork goes with Pages (Word processor), Numbers (Excel or Calc analog).

It is worth each cent , you have paid for that. Continue reading

Hey! Teachers! Leave them kids alone.

TransistorOne of the greatest talent is to make, teach, describe complicated things in the easy way. As person has magic to attract the attention of the people group, that make group to remember the subject and build imagination for complicated thing for the entire life.

I’m not big fan of the electronic, I had different classes related to the electronics at the university, electronic “looked” very boring for me. I can imagine and argue, that ~90% of the people, who attended electronic classes with me remember only the really basic of it. E.g. transistor is known word, but the main functions of it not (I’m not an “upstart”). Today I found outstanding description on the one book,

Transistor definition,

The transistor will likely go down as one of the greatest in modern history…

Transistor is tiny electronic device to control the flow of electricity. It has two key abilities: the first to amplify an electric signal, and the other is to switch on or off (1 or 0), letting current trough or blocking it as necessary.

Diode definition,

unlike a resistor, a diode is one-way street. Electricity (electrons) can go trough, but it can’t come back trough.

iWoz, Steve Wozniak with Gina Smith.

Well, probably if I had someone who describes the electronic in the similar way, I could be more interested in this subject. As well, such easy description stay on mind all life long, because it is an association, even then you do not touch these things at all.

Teachers are not supposed to be clowns, I agree. However, at the Latvian main technical university a lot of the teachers lack the ability to understand the fact, that some of their students have different level of the previous knowledge and a lot of classes are held in the “automatic” way, when teacher without any feelings and emotions are presenting the subject. Unfortunately usually students build just like “wall” against, so in result disrespect and incomprehension from the both sides. And students fell pretty good, when the teacher has trying to put himself/herself and best efforts to the process. Upon respect is built, two-side communication is possible, from teacher – his/her best to give the knowledge, from student – wiliness to get more knowledge.

Yes, I agree, that without any wiliness to knowledge, nothing is possible at the communication between teacher and student, however very motivated teacher is able to set fire for big groups of the students. That’s why talent is such important, that is described at the first sentence.
