MS SQL Server 2008 Database Developer

2011-12-15T14:14:00.000+13:00

I've just passed MS Exam 70-433 and now I'm a Certified SQL Server 2008 Database Developer.

It was not too difficult, especially if currently I'm spending 80% of my work time doing something with SQL Server :)

True Permanent Residency

2011-09-13T11:59:00.000+12:00

Now I'm a real Permanent Resident of New Zealand.

What does it mean?

Now my visa has no expiration date and I can live in New Zealand, travel outside, return to New Zealand any time. So now I glad that I (and my family) have a safe and nice place to live.

Online code formatter

2011-08-27T11:23:00.000+12:00

I know that a lot of online code formatters are available. I just found this one usuful for me:

Number to text

2011-08-27T11:14:00.000+12:00

I had to convert number to text and haven't found any nice implemenation in 30 minutes of googling, so I created my own:

using System;

using System.Text.RegularExpressions;



class NumberToText

{

    private static string[] _numbers = { string.Empty, "one", "two", "three",

            "four", "five", "six", "seven", "eight", "nine" };

    private const string _hundred = " hundred";

    private static string[] _numbersT = { "", "ten", "twenty", "thirty",

            "fourty", "fifty", "sixty", "seventy", "eighty", "ninety" };

    private static string[] _numbers11_19 = { "", "eleven", "twelve",

            "thirteen", "fourteen", "fifteen", "sixteen", "seventeen",

            "eightteen", "nineteen" };

    private static string _thousand = " thousand ";

    private static string _million = "one million and more";



    private static string _ConvertNumber(uint inputNumber)

    {

        string unitStr, tenStr, tenString;

        uint hundreds = inputNumber / 100;

        uint hundredReminder = inputNumber % 100;

        uint tens = hundredReminder / 10;

        uint units = hundredReminder % 10;



        tenString = _numbers[hundreds < 10 ? hundreds : 0]

                + (hundreds > 0 ? _hundred : string.Empty);

        if (tens == 1 && units != 0)

        {

            tenStr = _numbers11_19[units];

            unitStr = string.Empty;

        }

        else

        {

            tenStr = _numbersT[tens];

            unitStr = _numbers[units];

        }



        return string.Format("{0} {1} {2}", tenString, tenStr, unitStr);

    }



    public static string ConvertNumber(uint inputNumber)

    {

        if (inputNumber < 1000)

            return _ConvertNumber(inputNumber);

        else if (inputNumber < 1000000)

            return _ConvertNumber(inputNumber / 1000) + _thousand

                    + _ConvertNumber(inputNumber % 1000);

        else

            return _million;

    }



    public static string RemoveExtraSpaces(string input)

    {

        return Regex.Replace(input, "\\W+", " ").Trim();

    }



    public static void Main(string[] args)

    {

        for (uint i = 1; i < 2000; i++)

        {

            Console.WriteLine(RemoveExtraSpaces(ConvertNumber(i)));

        }

    }

}

RSS for your ASP.NET web site

2011-08-27T11:09:00.000+12:00

Sequence Diagram Editor

2011-01-12T09:37:00.000+13:00

Yesterday I found very interesting sequence diagram editor: http://sdedit.sourceforge.net/
It's free, it's small and easy to use (it has quite specific interface, but for me, it's easy to use!)

It has own language for diagram definition and provides very nice pictures (actually it draws diagrams on given definition).

For example, it uses this script:

bfs:BFS[a]
/queue:FIFO
someNode:Node
node:Node
adjList:List
adj:Node

bfs:queue.new
bfs:someNode.setLevel(0)
bfs:queue.insert(someNode)
[c:loop while queue != ()]
  bfs:node=queue.remove()
  bfs:level=node.getLevel()
  bfs:adjList=node.getAdjacentNodes()
  [c:loop 0 <= i < #adjList]
    bfs:adj=adjList.get(i)
    bfs:nodeLevel=adj.getLevel()
    [c:alt nodeLevel IS NOT defined]
      bfs:adj.setLevel(level+1)
      bfs:queue.insert(adj)
      --[else]
      bfs:nothing to do
    [/c]
  [/c]
[/c]
bfs:queue.destroy()

and generates this diagram:

In my opinion it looks perfect!

Poetry

2010-10-16T01:24:00.000+13:00

I was walking down the seashore this night and remembered a poetry from an old Russian book (this book was released in the middle of 20th century). I decided to translate this to English, so here is my humble attempt (I spent only about half an hour):

Swift sword's blow,
The arrow's prick, the shine of axe -
And world has disappeared in your eyes:
There is no sea, there are no friends,
You are alone.

But you are alone just for a while:
Valhalla's beam runs down to you.
The road to heaven:
It is strong, it is true,
Like Viking's arm, like solid sword.

And mighty steed flies by this road:
It is white as snow, it is pure as light.
Valkyrie rides this steed
With Wotan's wills and greetings:
He waits, he waits for you.

And you have got the place in heroes hall.
Then you take off like weightless smoke,
Like light steam, like pure clouds -
You and the messenger of heaven.

Autographed CD + t-shirt

2010-10-04T20:51:00.001+13:00

About one month ago I had pre-ordered and recently received a new album of Fran Healy (http://www.franhealy.com/). He is the lead singer and main songwriter of Travis band (I like their music very much). A couple of months ago I found some information about his upcoming solo album "Wreckorder" and decided to buy it.

So last week I found a small box on the doorstep of my flat. This box contained autographed CD and a t-shirt (see the photo below).

I listened to this album and may say only "Amazing!". Good half of these songs can pull my strings, like these songs were written about me (in my past).

In my opinion these songs are just stunning:

1) Anything

2) Buttercups

3) Holiday

Ebook reader

2010-08-07T16:06:00.002+12:00

I had read many cheerful reviews of new Amazon Kindle Reading Device (see sidebar image, description is available on Amazon web site) and ordered it.
So, now I'm looking forward to playing with it.
P.S. It will be shipped after 27th of August...

Listening and understanding

2010-08-07T15:37:00.000+12:00

Last week my Aikido teacher told me very interesting phrase: "If you are listening to someone carefully you will understand this person even if you don't know the language".
That time we were discussing a question of why I understand him better than my Russian teacher. And he told me that he is able to understand his japanese teacher even if my teacher don't have sufficient experince in Japanese.
So, to sum up: it is enought to listen carefully to understand anyone you want to understand.

Another exam passed

2010-06-17T10:48:00.000+12:00

I've just passed another MS Exam: 70-561 - ADO.NET Application Development
I passed it with score 895 out of 1000, which is good (in my opinion), because I haven't had even one REAL project with Entity Framework (only a couple of testing ones), and there were many Entity Framework questions.

Exam preparation materials

2010-05-17T14:02:00.002+12:00

Here is the list of materials I used for preparation for my last exam:

1) books:

MCTS Self-Paced Training Kit (Exam 70-503) - Microsoft Framework 3.5 - Windows Communication Foundation
"Microsoft Windows Communication Foundation Step by Step" by John Sharp
"Programming WCF Services, Second Edition" by Juval Lowy

2) screencasts:

http://www.microsoft.com/uk/msdn/screencasts/presenter/11/Mike-Taulty.aspx (see screencasts about WCF, all other ones are also useful, I'll have a look on them on next exams preparation)
http://www.dasblonde.net/2007/06/24/WCFWebcastSeries.aspx (webcasts by Michele Bustamante)

Especially important was to watch and study thoroughly these topics:

Windows Communication Foundation Top to Bottom (Part 04 of 15): Exceptions and Faults

Windows Communication Foundation Top to Bottom (Part 08 of 15): Instancing Modes

Transactions in Distributed Solutions with Windows Communication Foundation

Windows Communication Foundation Top to Bottom (Part 09 of 15): Concurrency, Throughput, and Throttling

From my point of view, all topics related to concurrency, instances are not too simple.

MS Exam 70-503 PASSED!

2010-05-17T11:29:00.000+12:00

Another step passed:
Microsoft .NET Framework 3.5 – Windows Communication Foundation Application Development (70-503)

I managed to pass this exam with score 916 out of 1000.

Now I'm an MCTS (MS Certified Technology Specialist) in Windows Communication Foundation.

Currently I'm preparing for exam 70-561 (ADO.NET)...

Old school T-shirt

2010-03-26T10:01:00.000+13:00

Last Wednesday (on Wellington .NET User Group meeting) I received pretty nice T-shirt, you may have a look on it here, for example:
http://dev.null.org/blog/item/200812081001_softbymic

It looks pretty old-style and only "true" desktop programmers are able to recognize the logo and remember "old good times" when most programs were single-threaded and have less then 640k of memory :)

Industrial production of holy water

2009-10-06T21:24:00.002+13:00

Recently I remembered famous phrase of Rudolf Sikorski from "Beetle in the Anthill" (Boris and Arkady Strugatsky):
"As members of COMCON-2 we are allowed to have a reputation of ignoramuses, mystics and superstitious fools. But we are not allowed one single thing - that is, to underestimate a threat. And if our house suddenly smells of sulfur, we must suppose that a horned devil appeared somewhere near and take any necessary measures, even if that means organizing an industrial production of holy water."
I remembered it in a case where someone asked me "Slava, why are you so nervous?" :)

At last - I'm in New Zealand

2009-09-13T18:04:00.002+12:00

Well at last I got to New Zealand, the land of my dreams!
My trip was uneasy as I may say: 16 hours by train and more then 30 hours on airports and flights.
I'll tell more details later, when I take some rest.

How to decompile CHM files

2009-08-02T19:29:00.002+12:00

Recently I bought Sony PRS-505 e-book reader. I reads a lot of formats (like PDF, RTF, TXT). Also it reads EPUB (public) and LRF (Sony internal) formats.
But I need to read my CHM books on that device.
So I see the following way of converting CHM into something readable:
1) decompile CHM into a set of HTMLs
2) create EPUB file

I found that every Windows user already has an ability to decompile CHM - it is easy as a pie, just execute

hh -decompile [target folder] [CHM file]

Now I'm searching how to create EPUB file (it must not be difficult, because EPUB file looks similar to zipped set of xml files).

Now I'm a resident of New Zealand!

2009-07-08T17:30:00.002+12:00

Friends, I've received my residential visa for New Zealand!
I started my application for residence long time ago (about 2.5 years) - and I passed this long way.
Cheers!

Interesting training I attended - Situational leadership

2009-06-08T15:43:00.003+12:00

There was a training in our organization last weekend. (to be precise: June 5 and 6). We studied "Situational leadership".
I was very surprised that it is quite old technique (end of 60s) but I've never heard of it and some my ex-bosses pretended to be very skilled managers don't know at all (or manage people without using of this technique - they just use one style of management).
I can repeat: training was surprising and simple ideas from such style of leadership were shoking for me (I realised that I did a lot of mistakes in my previos experience and how this method could be applied on me from the side of my bosses to avoid miscommunications and problems).

One of the most important Project Management skills

2009-03-05T18:20:00.002+13:00

Currently I think that the one of the most important Project Management skills is the Vision of the result.

So PM may not know how exactly things go and created, but it is vitally important for PM to know how complete things must look like. Sure the result have to be achievable (sometimes we can imagine such impossible things...)
And PM must be able to inspire his or her team to implement such Vision.

Well, the formula is quite simple "The Result = Vision + Possibility to Implement".

I'm sure these simple principles can be obtained from careful reading of books (and important SMART model), but as a rule information in books is digged in and sometimes it is not easy to get it correctly.

Trip to London

2009-02-22T02:04:00.003+13:00

Recently I've been to the UK. To be precise, from February 14 till February 17
Here you can see my photos: http://picasaweb.google.com/lysunkin/London

I'll write about my opinion and trip details later... Nevertheless, the whole trip was just awesome and I love London very much!

What I like in my new workplace

2008-12-04T13:41:00.000+13:00

I was slightly surprised with my new workplace. And it was not only my colleges (very open and helpful), but also the spirit of this company and environment.

Also I found very interesting things in conference rooms:
Do your whiteboards have memories? I guess - no (I have not seen such whiteboards in Russia, for example). You can draw something on board and then print it (just press a button and information from the whiteboard will be transferred on paper). When you print something off the whiteboard it stays in the memory and can be printed out again. But don't forget to wipe out all information from the whiteboard when meeting ends (at first it is not suitable for next meeting if attendants see your information, and also your information may contain some confidential things :) ).

And also I was impressed by universal printer-scanner-copier devices in office: they not only scan your documents, but also can send scanned materials by email. (Maybe I'm a caveman and my astonishment is silly, but such technical gadgets help me a lot).

So, in whole it is a very good place to work!

Some shortcuts for a better life in NZ

2008-11-30T12:56:00.000+13:00

Someone (one of my friends maybe) told me that prices in NZ is much higher then for example in the USA.

Possibly that my friend did not know about possible shortcuts ("pricecuts") :)

So, I was walking down the streets of Wellington and found very interesting market on Willis/Vivian crossing. Such prices just amazed me: some goods (oranges, other fruits and vegetables) were 3 times cheaper then in supermarkets. For instance: a kilo of oranges had a price of $0.99 (it is about 57 American cents or 16 Russian rubles).

Later on Vivian street I saw "Dick Smith Electronics" where I found very attractive prices on electronic gadgets (for example: $99 for a Logitec cordless mouse + 2.1 speakers - such things have the same price in the USA and 2 times more expensive in Russia).

I think the cost if living is not high here, I'm sure, definitely.

P.S. Also it's usual to have lunch by $10 or even less (10 bucks will be a reasonable price for something for lunch in "Great India" or "JJ Murphy's"). So it's cheaper then if I take the same amount of food in Moscow or even in smaller Russian cities (like Saratov).

First look at New Zealand

2008-11-22T16:47:00.001+13:00

I've put my photos from the "first look" on Wellington, New Zealand (I took a walk thought Wellington and made a few photos)

http://picasaweb.google.com/lysunkin/FirstLookAtWellingtonNewZealand#

I'm in New Zealand (my dream came true)

2008-11-19T06:05:00.000+13:00

Hooray!

This Monday I came to New Zealand: Auckland first and Wellington then.
That was a long trip from Moscow (thru Tokyo) - I was more then 20 hours in flight (about 10 hours for a trip from Moscow to Tokyo, more then 10 hours for a trip from Tokyo to Auckland, and about 1 hour for a flight from Auckland to Wellington).

And finally: I'm here! I cannot express all my feelings: almost is fresh and bright here.
I did not expect that the air of New Zealand is so intoxicating for me (in a good meaning of this word :) ). I've seen a lot of pictures of NZ and thought that all these photos were transformed in Photoshop like application to look more attractive. All these pictures were very close to original. It's a so clear, bright land.

I'll make a few my own photos and then put them here (or put a few links to my photos).

Cheers!

Most influencing books

2008-11-12T08:54:00.000+13:00

Here is a list of books which are influenced me a lot:

"The Seven Habits of Highly Effective People" by Stephen R. Covey.
"How to get control of your time and your life" by Alan Lakein
"Eat That Frog!" by Brian Tracy
"Getting Things Done" by David Allen
"The Alchemist" by Paulo Coelho (sure, I know that this is a fiction novel, but I like it anyway)

I'm going to enumerate and shortly describe the list of books which I've read during this year

2008-11-07T03:55:00.000+13:00

I'm going to enumerate and shortly describe the list of books which I've read during this year.
I'll do this ASAP (possibly even today).

I spent the whole year in improvement activity and optimization of my way of living and functioning - I even completely changed some of my habbits. All this happened bacause of books I've read.

As Russian writer Maxim Gorky said: "I am obliged to books for all the good in me" :)
So am I...

Changed my Blog appearance

2008-11-07T03:53:00.000+13:00

I've decided to change my blog appearance (color scheme, etc.) because not everything in my life so gloomy (previous schema was in dark colors).
Everything is great and positive!

Cheers!

I want to explain my reasons of leaving EPAM with more details :

1) My new employer offered me slightly higher salary (+ the same amount of money while I'm in a business trip)

2) Soon I'll be in a very interesting business trip (starting from the midst of November)

3) They offered me a bigger project (a small part of a huge project) with new technologies and the ability to "grow fast" (if I'm smart and well organized).

4) And also we developed a smooth process of integrating me into their business process and this new project.

So, I'm sure that were sufficient reasons to leave.

My last official day in EPAM Saratov

2008-10-25T05:24:00.000+13:00

Today was my official last day in Saratov branch of EPAM Systems.
(sure, I'll be visiting this office because I still need to transfer my knowledge of some project, but nevertheless: today was my last day here).

I deeply appreciate all my friends here (I've mentioned only a few good people)

In Saratov:

Alex Guzev (my old friend and team-mate) - for good job which we have done here
Evgeny Fedotov - for very interesting talks about TDD (Test-Driven Development) and Design Patterns
Pavel Boykov - for very pragmatic thinking
Vladimir Pan - for very important criticism of my work
Ekaterina Ermilova - for a very good advice when I was in trouble

In Mogilev:

Siarhei Prudnikaw
Konstantin Talanin
Andrei Saperski

So let all good people be happy and healthy and all evil ones - go to hell :)

How to manage your managers

2008-10-23T02:15:00.000+13:00

Once I worked on a project and constantly was having a problems with tasks and my managers.

The situation was as follows: I was receiving my tasks from several managers and all of them was angry (to say honest they were pissed off :) ) that I was bad in task prioritising and sometimes missed some deadlines. Sure, I tried to say something like that: "It's enough things on my plate". But they were not happy anyway and each time I had to describe all my tasks and what's wrong with one more task in my list.

I think I was not too smart to manage this problem right and eliminate all unnecessary tasks.

So, here is the diagram of management which should be eliminated:

If only I was really smart that time I had proposed this method of management my activity:

But this method requires information about most influential manager (supervisor), which should be identified and used as a leverage to influence on other task submitters. So all would justify their tasks in the eyes of my supervisor before making an asignment.

Or another approach may be used:

As for my organization, a special software system could be used and I was just stupid that tried to work without yells of anger that anyone assigns tasks using email, phone or verbally.

Singleton in C#

2008-10-13T20:15:00.001+13:00

Once I've found a Singleton pattern implementation in C#

class Singleton<T> where T : new()
{
    private static readonly T inst = new T();
    public static T Instance
    {
        get { return inst; }
    }
}

I was suprised by the elegance of this code snippet (and also it is thread safe!)

This code could be used as follows:

internal class Singleton<T> where T : new()

{

private static readonly T inst = new T();

public static T Instance

{

get { return inst; }

}

internal class Single

{

public Single()

{

System.Console.WriteLine("Constructor!");

}

public class Test

{

public static void Main(string[] args)

{

Single sss1 = Singleton<Single>.Instance;

Single sss2 = Singleton<Single>.Instance;

}

Oracle script for index creation

2008-10-03T02:20:00.003+13:00

Once I had a task of creation a lot of indexes for Oracle DB (that DB had no indexes for columns used for table linkage).

I wrote a simple script to automate this task:

So this script built indexes descriptions which could be edited and executed.

Try to teach enyone and you'll be more educated too!

2008-09-25T23:52:00.000+12:00

Try to teach enyone and you'll be more educated too!

Currently I'm trying to create a webcast about dotNet 3.5 features (for our internal training). I did not know that this process is so difficult!
So I must polish all my knowledge and be able to explain coplicated things easily (I realised that sometimes I can exaplain complicated things in more complicated way :) )
Also, it's hard to speak without an audience: just sit still and speak to a microfone...

But anyway it was very important experince!
I'm going to create a few webcasts soon, because it will teach me the following stuff:
1) get to know more about the topic you consider in your presentation
2) get more experince in speaking skill
3) gain presentation skills in whole

That is it for now. I'll write about further progress.

Мысли по поводу лидерства

2008-09-25T19:35:00.000+12:00

Возникли у меня мысли по поводу лидерства и вот они какие (почему-то возникла аналогия с движением по дороге):

1) есть такие люди, которые хотят быть лидерами и даже официальные должности имеют, но они похожи на мощные полуспортивные автомобили - они включают высокую передачу, быстро отрываются, улетают далеко вперёд, а потом (когда им надоедает ждать где-то за поворотом), возвращаются к основной массе и начинают распаляться и орать дурным голосом, что все "тормозят" и вообще никуда не годятся.

2) другая категория: трактор "Беларусь" - они официально признаны (легитимность имеется), но движутся медленно по дороге, где обгон запрещён и всем приходится плестись за ними и пока такой "лидер" не наберёт нужную скорость, то никакого движения не будет.

я был свидетелем работы обоих типов таких "лидеров" - один уносился вперёд и потом всех ругал за медлительность, а другой плёлся и настойчиво мешал прогрессу группы (например, проводил митинг на 2 часа, на котором ничего так и не решил)

Каков же выход и какой же идеальный лидер должен быть:
это тот, кто даже если и имеет "мощный мотор", то может держать себя на небольшом отдалении от основной группы и задавать общий темп движения, помогая основной группе держать тонус... либо (если он ближе к типу "трактор Беларусь") просто не мешать общему движению и время от времени помогать выбраться участникам группы из ямы (он же - трактор! :) )

Why did I give such name to my blog?

2007-04-26T22:23:00.000+12:00

My original russian name Viacheslav has the following meaning (in ancient russian language):
viache - great, eternal
slav (shortage from "slava") - glory

So, I gave such name to my blog. It's very simple :)
