The real goal of Agile.

The 3rd Agile Gathering was conducted by Agile Ukraine in Kyiv on 9/10. I was participating as humble developer from our team listening to people who have already achievements (or at least pretended to have) in implementing agile technologies.

Being a participant of previous two gatherings I feel some remarkable symptoms, which probably may cause me to review agile technologies in different manner.

Organization crew strongly wants to sell certifications. So, they encourage everybody to become SCRUM certificated master (SCM), to have affiliation of the international agile community. Then you probably gain SCRUM Certificated practitioner. And the third stage of that is to become SCRUM Certificated trainer to be able to provide certification for other people. Capacities are growing: soon one more battalion of SCMs will appear in Kyiv. IMHO, it rather makes SCM devalued than increase percentage of successive projects, but let's see it together in the future.

Reporters lean to tell about their projects and how effective they are with agile. That's great, but why main accent is made "How to make your business applied for agile"? They prefer to answer question: "What kind of project should you manage to implement agile?", not "How to apply agile on some project?":
- How about deadlines? How can you check if you are meeting deadline or not, implied from your estimations?
- We do not operate with term "deadline". We have workflow, sprint, backlog, but do not use deadlines.

Well done. Thanks! Only challenge is to find such brave customer, that doesn't care about deadlines!

As for me, it's pathetic point of view: instead of appling process to business, let's make your business applied to the process. Bringing business to agile is even more ridiculous thing then bringing agile to agile software tool.

Accordingly to report of Adam Byrtek about his company Codesprinters agile techologies can be applied for small teams developing web-based solution on languages like Python. Unfortunatelly, that doesn't impress me much, because I can't drive out requirement of my customer and say: "Dear sirs, instead of delivering desktop client-server application based on Win32, we offer you web portal developed in Java".

Indeed, the most crucial thing is how to convert methodology to something worth to decision making people: would it be customer, headmaster, sales or owner you should represent your approach in his values.

I remember very remarkable book Critical Testing Processes by Rex Black. It impressed me very much because author managed to convert his technology to business benefits. Actually this is essential point of his thinking. Look at the first frame of his presentation here: his approach serves to save money. His listers don't even think what business values will be spent on implementation such QA-driven development. Because his approach is business value itself!

I can see community is progressing comparatively with last year: among people bedazzled with some extra-special-new-super-cool methodology appears essential community of pragmatic specialists, who will probably reenforce agile stronghold. Askhat Urazbaev from Luxsoft Moscow emphasized that agile is implemented not for agile, but to make project successful (in the meaning of business). I strongly belive in that and I also believe that agile will make software industry more successful, but for now I didn't get any good ideas how to make agile benefits evident for business. And this is very disappointing ...

Antipattern introduction seminar

    On Monday (09/10/2007) I was holding workshop about Antipatterns in our host company Ciklum. Attendance was quite low, but anyway I know start can't be easy.
    The topic is quite interesting, but since workshop was going to be mainly based on single book "Antipattern" by W. Brown and company, I strongly decided to brighten up it with my own experience. Project I'm involved in is all geographic map of Antipattern, so I had enough examples to make presentation pretty close to reality.
    I have found one peculiar thing: some people are really appreciate commiting to the main topic of presentation: they were steadily asking question and sharing their experience or opinion. Once I thought it's not good that reporter is frequently interrupted, but I really like it now. Only suggestion, that he (reporter) should be adequate on interrupting: to not argue very much and to know when to stop paying attention on the active listener.
    Next time I would rather have something like technical club, where all participants will be more or less equal ...

    And I believe I already have some ideas ...

Windows 2000 must survive!

3 years ago I have switched from Windows 2000 to Windows XP. It's already year since WinXP is issued, but I have surprise intention to return to Windows 2000 again.
Today I have successfully compiled Outlook Integration solution in VS2005 based on new VSTO. And to my own surprise it was done without any VS extentions, w/o .Net framework 3.0 and even without Visual Studion itself. The secret?
Oh... There is no secret at all: VS2005 uses msbuild.exe to compile own solutions. It adds some tolerance to it, but my general build engineering approach is too keep build server and development as lean as possible. The thing I dislike most of all is when somebody updates list of prerequisites of our software and particulary preinstalled software necessary for development. My will would be to be able to compile everything in commandline without any additional tools.
In next post I'd like to describe this process in detail, but today I would like to concern attention on main principle:

Build process should be environment independent.

I.e. irrespective to environment that exists on build server the result should be invariant.
Some days ago we have established new build server and I accidently realized that it works different in testing environment. I swear to avoid situation like that in the future.
Seems to be like we are striving to a catastrophe?
Oh, yeah, we are: it happens when we try to deliver our soft built on new server to customer who has version of the old prerequisite ...

Somebody thinks that update is some kind of Tivoli. Oh, dear sirs, you are mistaken, it is some kind of Ragnarok!

Any good reason to have firewall?

I have been in trouble with VMWare so many times, that even now, when I'm deeply under pressure, I've started investigation. So, main question: how to deploy virtual machines host on fresh PC where firewall is used.
The only thing I know is that firewalls are special tools to control and restrict incomming and outgoing traffic within local network and in Internet. Before that I have used it rarely. That's some kind of phylosophical question: Should I it be used on home PC?
It is said that there are very manu malicious things downloaded to local PC from internet. But how can tool that requests if application lsass.exe can access address 198.162.1.4 port 443.
Well done! Challenging question. And what if I say no? Where will I get refuse next time?
Firewalls are all user-unfriendly. To be honest, they are not for common user. Let system administrators have deal with them. Home PC are buried under junk soft normally because their masters want to download this and that. Strange, how some people can proud with their "downloading". Oh, man, stop downloading that suxx video - you have no time even to see worth things!

So, let's come back to my investigation. So I have downloaded version of .PCTools firewall+. Lite and precious thing free of charge. The newest version has some interesting features:
They provide 2 modes of creating rules for the firewall: normal user and expert user.
The latter means that user will be requested for each attempt to connect distinct port and more presice rules will be created. Before that I have tried to use ISA, Kerio, McAfee and this soft looks quite good.
Another advantage is predifined rules that are spread over PC Tools which allow user fast customization with less amount of stupid questions.
So I have installed PC Tools Firewall on my laptop (Acer TravelMate 2700) with Windows XP SP2. Before that I've installed VMWare workstation 5.5. PC Tools install so called PCTools Driver that apparently used to track hardware activity. To my surprise those drivers are conflicting with VMWare drivers. PC Tools refused to work when 4 Windows Services belonged to VMWare are working. That's suxx! I knew that at my job people also have headache using VMWare and firewall. And even worse, that PC Tools doesn't output any presice info why did it fail! Only message "Failed to initialize firewall drivers, please try to reboot your machine. If the problem persists please contact PC Tools support". This case I have posted to PCTools forum.
Another problem I've encountered and also could not resolve is that Firewall don't allow to lock workstation. This is not so critical for me, since I don't lock my PC, but this might grow up into a great impediment for the team.
I have anyway registered my copy of PCTools firewall. I hope those guys won't left my suggestions without answer.

Although firewall doesn't make much distortion to booting process some of booting process are slowdowned. And I have measurements for Microsoft BootVis. After installing Office, Firewall, NetBeans and Visual Studio loading windows services take twice longer time then before.
$Sic transit gloria mundi!

Requirements metrics

This week the hotest question among Agile Group Ukraine) was discussion about approaches how to measure requirement completeness and feature readyness for shipping. There were basicly 2 basic opinions: Are there any defined approaches to detect if you have ready feature or not.
Strange why people things that business value can be measured before you have money flow?
My conlcusion is that there are tracking methodologies to measure development tasks and there are tracking for business tasks also. But there is no methodologies how to correspond business and development tasks ...

Web application vs. desktop

    Nowadays I can see so many developers leaning to the web development as to something very promising. Being involved in process of development that represented to the end-user as desktop application, once I was quite excited with debates about what kind of application is the best.

    Whenever somebody asks me what kind of application I like to develop, web or desktop, I reply that my style is console application. In fact, lack of moderation became a curse of the modern society. And IT branch is not an exception: Each 2-3 years interface outlook is entirely changing: the most prominent software manifacturer are trying to make people require more and more flashy widgets for the user interface. But I do believe that the basics of all successful systems will be functionality determined by command line. Everything is going to be automated and command line is essential part of this. Look for instance on Perforce - versioning control system that we use. Indeed, P4 has provided very convenient command line that covers all needs of the software developer. Their clients (which are actually 2 desktop and 1 web interface client are secondary.

    Look at the google: simple interface for basic needs, - that's a formula of success. Gmail is preferrable mailer, google.com is the best search machine. You can be novice or master and use this interface in the same way. Oh, how user friendly it is indeed!

Message to IT Gurus

Dear IT Gurus!

I always used your publication to support my thoughts expressed on different meetings, jobs, simposiums and discussions. Whenever I represent community, but not act as a single man, I become more persuasive. I always suffered from the fact, that I can't thank you for that. And since today I have a new hope that situation is going to be changed. On this blogspot I will share my thoughts in software development, architecture, management and philosophy and I hope one day my marginal contribution to world IT communuty will be positive.
I don't fear that I'll have lack of material: my cup runneth over with my own thought, that can supply even more than this blog :)

One day you will know me, why not today?
