For quite some we all used to use websites. And one some of these websites are creating accounts and this requires us to use passwords. From technical point of view there is nothing that prevents us using any character that you can type on keyboard including Chinese and Japanese. And the more characters allowed the safer password is. Imaging that password only allows 3-character passwords. For only lower-case English letters there will be 26*26*26 = 17,576 combinations. If upper case letters are also allowed, then you have 52*52*52 = 140,608 combinations and that is 8 times more. But if Chinese characters are also allowed then 50052 * 50052 * 50052 and that is 125,390,405,740,608 combinations.

But as you can imagine

Many people heard that all cars produced for last 20 years using “chips” or processors to control different operations of car. So basically, it is small computer that for example calculate proportion of air in petrol for engine based on current speed, quality of petrol etc.  And all computers require software, and this is program computer executes. Technically it can be done in hardware, but it is quite expensive to product custom chip for every operation and quite expensive to change. So, using general processor is much more effective.

And as everyone knows any program may have mistakes (they called bugs in software industry). Of course, probability that simple program has bug is quite low. But the more complex program

There are many people who never used more than one monitor and this post I would like to show them why you should try multiple monitors.

I myself when I did read that Windows 98 will support multiple monitors thought something like that: Why anybody would need more than one monitor? Sure, say game developers would need more than one and perhaps some artists but normal people sure never need more than one. You can always switch to different window. That were my thoughts. And I was wrong. Few years later in our company everyone had two monitors (and later we switched to use 3 monitors). It was game changer.

You can see and work with two applications at the

Recently I realized that by some reason don’t like big monitors. At my work we usually have 3 monitors. Usually one big about 32 inches and 2 monitors 20-24 inches. Also, we have few “roaming” spaces. These spaces for people who visiting our office for whatever reason. Usually people travel with notebooks and as result these places have all appropriate connectivity for notebooks. HDMI, Display port cables. Also, these places have wireless keyboard and mouse.

But I found that even people with Mac Book Air with 11-inch screen never use bigger monitors and I don’t understand why. I understand why they don’t use keyboard because it is Windows keyboard but why not use bigger screen specially when screen have 6

Some people state that electric vehicles (EV) are green, some of them state that they are not. Who is right?

Why some people considered EV are not green? Well total emissions (TE) of the car are calculated like this: production emissions, emissions during usage, and utilization emissions. For EV first and last are quite high and that allows these people to state that EV are not that green. Also, they stated that most electricity generation produces emissions as well. They also stated that production of solar panels are quite dirty as well if you state that you are using solar panel to charge you EV.

Let’s assume that TE of EV is higher than normal car. Should we stop using

There is long standing battle between engineers and other departments like marketing. And very often they are going out of sync. For example, engineering team would like to produce nest product and it became quite expensive. Or marketing team forces engineering team to product cheap product and it is not reliable. Sometimes it moves company to quite bad spot. Let me explain in detail.

Long time ago I dreamed about Logitech high end gaming mouse. I thought that Logitech is the best in that area. And some time ago I got it as present. It was great mouse, but left mouse button stopped working after 2 years. It was $120 dollars mouse and to be honest I didn’t even play

One thing I don’t understand about electric car is that most of them looks simply ugly.

Let’s take first Toyota Prius for example. It is hybrid car and looks like designers would like to make something “futuristic” and not typical. I don’t understand why they just didn’t use normal sedan shape or in case of hatchback use nicely looking one? And last Prius is even uglier than before.

Another example is first Nissan Leaf. Extremely ugly car. I would understand if that car was extremely cheap, but it is wasn’t that cheap. And I’m totally sure that even with cost restrictions there were possible to make it look much better.

And another example is BWM i3. Another great example of

As you already should know SSD much much faster than traditional hard drives. And if you would like to buy one which should you buy?

Firstly thing, you have to figure out how much space you need. Usually these days I would recommend having around 500Gb SSD drive. You will install Windows and most software that you use everyday on SSD and rarely used stuff or stuff that is ok to be slow or just huge stuff on hard drive. If money is big issue, then you can buy 250GB and depending on how often you start computer per day you can install Windows on SSD or hard drive. I would not recommend buy 128GB drive unless money is huge

Most of us own Wi-Fi router and many of us did own few of them. And here is common list of issues with most household routers:

* Lack of stability. After some time, Wi-fi will go slower and slower, sometimes you cannot even connect or in extreme cases it can disappear completely.
* Freezes. Router will stop transferring data and you will have to restart it.
* Lack of features. Most common home routers have just very basic features. Some of them have more exotic features and but very often they didn’t work properly.
* Lack of extensibility. You cannot add any feature by yourself.
* Short support live. After year or two your router is
