Tweet September 1 is not only the day of knowledge, peonies, and teachers, but it is also a day of fun for more than 3,000 IT specialists in the NSC “Olimpiiskii“. Truly speaking, I have not seen anywhere else such a long queue for registration. When registering, in addition to cute notebooks-pens-markers-pins-magnets, you could also get a card of the first off-line social network, RFIDLE. The card is linked to my Facebook page, and with the help of it, I can give likes, add friends and upload photos using special terminals. The idea is excellent, but unfortunately, terminals often denied. In a couple of days, RFIDLE sent me a questionnaire by mail, and it turned out that we became participants of a beta testing, so let’s hope that developers are already fixing the system. “We are here to celebrate!” said IT Jam slogans. On two stages (under the titles “New ideas and technologies” and “From vision to implementation”) technical gurus told stories of their success in a simple and humorous way. Apart from Ukrainian speakers Max Istchenko (founder of the well-known DOU Ukrainian developer community) and Michael Zavileiskii (General Manager of the DataArt company), there were also foreign guests: Christopher Marsh (technical developer at AKQA), Greg Young (independent consultant and entrepreneur), Torben Maygaard (Ciklum founder) and others. Companies raffled off licenses (I, for example, wanted to win a license from JetBrains for Resharper, but alas, failed to), cups, T-shirts, Lego; held competitions and polls (DataArt gave everybody beans in bags for voting; some members even took them home, maybe in order to plant). But I was lucky enough to win a 20% discount on the preparation for the Microsoft certification in the training center, which is also good. Around the pavilion, there were Chucks Norris with jokes and a different stuff for entertainment. But the most important thing was going on in the community spots, where developers of different areas were communicating and exchanging contacts. Ironically, I almost missed the .NET lectures but had a great time with the guys from Podcasting. It was very entertaining to learn from the “inside” how to create podcasts, as I often listen to Mikhail Marchenko and to his podcast “Frankly about IT...

Tweet The first of September. Young children go to school with large bags and flowers, and big kids are going to the most anticipated in the Kiev IT-event of the fall, but without bags and, of course, no flowers. This year, we will communicate in 5 areas to suit all tastes: .NET, QA, Web Development, and the Mobile Java (hope for Java and .NET pavilions will be located far enough away from each other, given the perennial holy wars of developers). By the way, on IT Jam site are presented various Community Spots (.NET, IOS, Agile, etc.) and registration still open. Well, see you on September 1 in NSK “Olympic”! And let everything be in the jam 🙂...

Tweet I’ve visited the .NET Saturday organized by the Ciklum Company on May 26. I’ll tell you a little bit about my impressions. The program was really nice, exactly as the organizers warned. There were: Eugene Zharkov – “Windows 8 Metro App: JavaScript Dark Side”; Petr Afanasiev – “Perfect API: ASP.NET Web API inside!”; Sergey Koshel – “When optimistic lock is not a case (.NET/SQL)”; Vitaliy Domnikov – “F# – To Iterate is Human, to Recurse, Divine”; Alexandr Ivanitskiy – “XAML – a markup language for WPF, Silverlight and Metro applications”. In addition to the main screen, there was an additional screen installed for tweets with the CiklumNET hashtag, which perfectly entertained the audience. It is a pity that I couldn’t attend all the lectures, but Vitali’s lecture on F# made a great impression on me, however, the lecture by Alexander was saved only by trolls twitting about cups, women, and dresses. So, from now on, I will visit meetups in Ciklum more frequently. Oh yes, I almost forgot. I promised to try F# and finally did it. The program is the calculation of factorial of the n number. Click to toggle codeblock 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 // Create function for calculating factorial let rec factorial n = match n with | 0 -> 1 | _ -> n * factorial (n - 1)   // using System open System   Console.Write(@"Enter n = ") let n = Convert.ToInt32(Console.ReadLine())   // Calculate and write result let result = factorial n Console.Write(@"Result = ") Console.WriteLine(result) // Create function for calculating factorial let rec factorial n = match n with | 0 -> 1 | _ -> n * factorial (n - 1) // using System open System Console.Write(@"Enter n = ") let n = Convert.ToInt32(Console.ReadLine()) // Calculate and write result let result = factorial n Console.Write(@"Result = ") Console.WriteLine(result) It is really possible to write programs on this functional language quite quickly and efficiently if you want to work with math functions. Dark side is the same: you have to think...
