How to write a haiku poem?

Without any introductions ^^

1. Haiku is a kind of Japanese poetry. It consists of three lines: 1st line - 5 syllables, 2nd line - 7 syllables, 3rd line - 5 syllables.
2. After signing the alliance between Japan and Nazi Germany, the number of syllables ​​can be arbitrary for European languages but the proportions must be observed. 3rd line should always be a little bit more than others.
3. Haiku consist mostly of metaphors as well as there is no need to present personal pronouns. Also, it is advisable to avoid commas.
4. Typically, the subject of haiku are some personal experiences, mood and what is happening around you. However, all this must be veiled metaphors and be impersonal.
5. The first two lines should relate the plot of haiku and the last - bit abstract and unexpected final.

An example of a haiku:

Warm and nice place
Light can be nothing or something
Predator awakes

Explanation: I'm sitting in a room at the computer. Monitor lights and I can do something useful or do nothing through it. I hear that the cat awakes and meows. The ratio of 5-8-5, no personal pronouns, the plot is not obvious, the ending is a little abstract and can mean anything :)

How to improve concentration?

A little underrated skill because it is impossible to learn anything else without it :)

1. Know yourself. The first few days watch and notice what is usually diverts you to understand what need to fix. In addition, it will be useful to know your biorhythm to understand when you are most active.
2. Silence. When you working on something, you should not be distracted by anything. Try to create the pre-conditions which allow you to work in silence.
3. Planning. As thoroughly as possible. It will be easier to avoid any further thought the process.
4. Motivation. Find the reasons why you have to do it and/or why it could be interesting.
5. Competition. Set some additional tasks, such as to make this work for 10 minutes, etc. Excitement usually boosts interest.
6. Working environment. Mess around not noisy but just the existence of it can be annoying and shoot down concentration.
7. Relaxation. If you feel nervous before or during work, it is better to calm down at first. Another way you can get to the stress in this mod. In general, do not forget to make pauses time to time.
8. Thoughts. Try to get rid of all the thoughts that are not relevant to the current case as much as possible. Pretty simple exercise to practice concentration.

Technically, the concentration is not a big deal. Just find and get rid of all that prevents you complete your current work ^^

What is better: M4A1-S or M4A4 in CS:GO?

First, I have to say that M4A4 technically better in the current patch (11.06.2015.) but let's look at everything step by step :)

M4A4 advantages:

1. Damage. M4A4 is little stronger than its alternative in this terms.
2. Spray. In the current patch, M4A1-S has more complicated spray and the weapon has become more difficult to control at close to medium range.
3. Amount of rounds. M4A4 has larger clip.
4. Tactics. With M4A4 easier to hide because of the size of the weapon and you can cs go backache without fear of run out of ammunition.

M4A1-S advantages:

1. Accuracy. M4A1-S more precisely, it is much easier to aim at long distances by short bursts.
2. Silencer. If you quick kill enemy in the back or side before he noticed you your late position will remain unknown.

Professionals: Players on tournaments usually play with the M4A4 now. Rifle with a silencer generally used by snipers who did not re-learn in the new patch. Until this patch all mainly played with M4A1-S. So, when the two guns were balanced professionals prefered rifle with the silencer :)

Is there mutants in Chernobyl?

1. After the Chernobyl accident, a huge area around the station was covered by radiation. This had an impact on the entire ecosystem - flora and fauna.
2. There are often born mutant animals, forests have acquired a reddish hue, the ground water was contaminated and people who have been subjected to radiation often have miscarriages.
3. All mutants that were born lived only a few hours or days because their mutation did not allow them to survive. There no dangerous mutants in Chernobyl.
4. In general, the area around the Chernobyl nuclear power plant is pretty safe and habitable. The radiation background is not very different from the big cities all over the world :)
