This is a story about me choosing the notebook for maintaining this blog.

Usually I am writing about something related to technologies which I am either exploring or training. Sometimes it’s about non-technological parts of the training or lifestyle. Something that consumed considerable amount of time to learn or get to. I’m sort of showing a shortcut to others and we usually call it “sharing of knowledge and experience”.

Since I am very serious about keeping my blog to be a useful and creative place, I decided to devote more time to it – especially the time when I am most mentally capable. And during that time I am usually far from my main 17” laptop – heavy powerful gaming-class machine which is theoretically portable.

So I made a decision to purchase a laptop especially for blogging. Taking into account that this blog doesn’t bring any income – pretty much enthusiastic move. But however, I’ve started with research. More...

One of the most frequent questions I get as a trainer, is about certifications and their real value. Opinions regarding certifications vary from “useless piece of paper” to “paramount” and the reason for so diverse opinion is either experience or lack of it. In this post I will try to explain modern IT certifications from a more practical point of view.

During my career of Information Technology Trainer, while spending most time training system administrators and software developers in various disciplines, I’ve also got a lot of valuable feedback from HR specialists and business owners. I’ve organized seminars on certifications to explain their value or in some cases – lack of it, and realized that certifications are like Terra Incognita for vast majority of HR specialists and even IT managers. But it shouldn’t be that way, so this post is also for HR and those who aren’t certified yet but think about whether it’s necessary or not. More...

During my career as a Microsoft Certified Trainer, I’ve been training .NET software developers and Windows system administrators – usually they were well established professionals longing for more knowledge and ready to purchase a training course instead of a car.

But there were people, and they still appear regularly, who suddenly make a decision to become a software developer. Either it’s because they were ignited by the idea and believed in own capacity of writing new software, or out of curiosity or any other reason – be it money, prestige or worrying about own future.

So this post is for such people. If you are considering to become a .NET software developer and wondering what should be your first step – I will do my best to explain it right now. If you are seasoned .NET software developer, then perhaps you won’t find much useful information here, but you’ll have a link to give when someone will ask you that question – “I want to become a software developer, what should I do?”.

How to make the URL of your page look more user-friendly or just make it self-explanatory? And anyway – look different from what it really is? In ASP.NET version 4 it’s easier than ever.

Why would we need that feature anyway?

It’s been quite popular trend in web development since the very beginning of dynamic Web – first, we didn’t want anyone to see the extension of our files, as this posed a security risk. Anyone, who could see that our page is actually an ASP page, would understand that you have Internet Information Server, which was considered “dangerous” at that time – not even because it was too bad, but because Windows NT 4 Server was user-friendly enough so people wouldn’t need to be MCSE in order to install and run web server. It wasn’t hard for Linux either, but Apache didn’t offer any dynamic contents out of the box. More...

The new culture of making business “more social” brings so many new possibilities and chances, it’s hard to analyze the consequences of every step you take. We are doing so much in order to use the latest features of the web, that don’t recognize the jeopardy hidden in most innocent things we do.

In October of 2011 I took an experiment, which lasted for two months and gave me so interesting results, that I couldn’t resist to share. For some of you these findings could be shocking and reveal something new, but the reason for the experiment was purely to prove what seemed logical even without the experiments. More...

This is my second post about Microsoft Visual Studio 2010 Team Foundation Server for Software Developers. The previous one is here.

Now that you know how to submit your code to the source control, associate work items and use that information in your daily work, it’s time to learn the rest two things we skipped in the first part. The Branching and the Shelving.

Team Foundation Server is an Agile-oriented platform, and therefore many of it’s concepts supports the existing models of Agile Software Development. One of such models is Source Code Promotion Model, which basically means that your code moves through 3 stages – development, testing and production.

A word of warning: each model of Agile is a double bladed sword. It expects you to meet the conditions which will make this model effective, and if you fail to comply – you’ll get ineffective implementation, which could ruin your software development efforts. In case of Promotion Model, make sure you have a dedicated team of testers – not just developers from other project who came to rescue, but professional testers who are not doing any development. If you don’t have dedicated testers – forget about Promotion Model. More...

ASP.NET engine is a wonderful thing. It does so much for you, that in the past could take ages and would earn you the title of demigod of Web Development. In some legacy languages, like PHP, it is still the case. For example, things like Localization and cross-browser support are very natural and automatic in ASP.NET, they don’t require any time or skills. You can add support of more languages, different output formats for date and numbers, add Ajax powered controls, caching, data access, perform various other high pilotage figures without thinking. I remember the time, when saving data between post-backs was an issue, and in ASP.NET it was solved by implementing the VIEWSTATE feature, which saves the state of page controls in one hidden field between submits - that feature alone worth a thousand words.

But ASP.NET comes to the rescue not only in obvious and direct ways - some features were introduced for one purpose, but perfectly helped in other areas. And one such area is Search Engine Optimization, or SEO. More...

A long time ago, when dinosaurs were still operational,  we tried to improve performance of our HTML / CGI pages by various ways, but also having different goals for such improvements.

In the dawn of web, when U.S. Robotics 14.4kbps modem was a de-facto standard and traffic compression wasn’t widely implemented by ISP call centers, our biggest concern was the size of our files. I wouldn’t say “output”, as it was mainly static, but even when it was dynamic, like the output from CGI modules written in Visual Basic 4 or 5, it was paramount that users would not wait more than 2 seconds to get the HTML part of it.

Now even mobile phones are having unlimited data plans, home connections reach 100 Mbit/s heights and in order to decrease the size of the output we just have to tick a checkbox in IIS, so the output – be it static or dynamic, is compressed. So the era of “HTML optimizers” – tools that remove extra spaces and “unneeded” tags from your markup, is over.

Another thing that helped us to avoid traffic jams, was Ajax. It killed 2 rabbits with a single shot – decreased the traffic flow by only up/down loading the data our application needs at this time, and thus increased the response time. But this came at a cost.

Each small callback made by Ajax is no different than ordinary callback, except that it transfer smaller amount of data. But it’s a connection nevertheless. Even if keep-alive is used by browser, it still consumes a connection from server and still there are protocol issues involved. More...

It appears like in some things Chinese have more sense than the rest of the world. According to the article, they are going to cancel majors (i.e. higher education programs) which don’t lead to employment. They are going to analyze the stats of employment for those, who finished their majors and how lucky they are to land a job. So, if you are teaching Turbo Pascal and call it “Computer Science”, your days are numbered. If you teach it in China, of course.

I wish the same would be implemented in EU. During my career I found out one thing – an IT specialist with higher education is less preferable than the one without it. The reason is simple – higher education in Eastern Europe works just like in “Profession” – novel by Isaac Asimov. Dumb memorizing of irrelevant data which won’t do any good for business. They are not taught creativity and open-mind behavior.

Besides, the situation with employment becomes so interesting for those mentally challenged IT administrators, that some of them become very… I almost said “creative”… In finding a new job opportunity.

According to Security Week, a 26 year-old Hungarian male called Attila Nemeth hacked into the network of American hotel network Marriot through some dumb social engineering technique, and then… Tried to extort the employment opportunity at that company, at his terms. And as if it wasn’t stupid enough, he sent them a copy of his passport, and used plane ticket paid by Marriot to come for his job interview. After he was “interviewed” by Secret Service “HR personnel”, he’s about to be employed by one of American prisons for next 15 years and during that time he will have to pay up to $ 1 million to Marriot.

This makes me think, that Hungary has problems with two things, and one of them is employment.

Talking about employment and HR, a new research shows, that there is a direct relation between intellect and the sense of humor. Apparently, the sense of mirth is a reward given by brain when you discover the logical error in statement. According to my own experience and opinion, research results looks valid and natural. Bad news for people with undeveloped sense of humor.

As discussed previously, there is a noticeable trend in casual IT these days – cut spending on IT infrastructure management as much as possible. Companies are using all chances to eliminate the “human factor” from systems administration, and while it’s scary for incompetent administrators, it adds to the innovation factor of modern IT management offering.

So it’s quite controversial trend. But trends of that kind are very natural for innovation. Let’s see what it’s all about. More...
