Cloud as a Story - Vunvulea Radu

This days Microsoft launched two new types of instances – A8 and A9. This two new type of instances are like a bulldozer from the perspective of the available RAM memory and processor. Each of this machines has 8 and 16 virtual cores and 56GB and 112GB of RAM memory. Yes, you heard me good 112GB on RAM memory available on cloud instances. For customers, that has intensive work to do this is a great news. Starting from now it will be pretty easy to have an intensive processor tasks that are processed on the cloud, without having to use multiple machines. Another opportunity is for the applications that needs to use a lot of memory – cache systems for example. For this kind of system, having more than 100GB of memory available is great. If we think a little bit, we can imagine a scenario where we have 100GB of data loaded from a relational database into a cache. This is great! But, this is not all. This new kind of instances are more than an instance of steroids. This are a new gener...

This year, CodeCamp and ITSpark started the year with full force. We organized 3 events in Cluj , Brasov and Sibiu where we talk about different topics like software quality, code metrics, HTML5, SignalR, JavaScript, Sonar, Virtualization, Hyper-V, System Center 2012 R2, Private Cloud and so on. Now, it the time to make public all the slides content and videos. Below you can find all the content related to this presentations, Managing Code Quality - Radu Vunvulea Managing code quality with SonarQube - Radu Vunvulea from ITSpark Community Managing code quality with SonarQube - Radu Vunvulea from ITCamp on Vimeo .

MTBF - Meantime between failure In today post I would like to talk about a software metric that can give us information related to the quality of our product and how stable it is – Meantime Between Failure. This metric measure the time interval between the moment when a failure was fixed (and the system is stable) until the moment when a new failure is detected. We could say that this metric measure the time interval when the system is up and running. Using this metric, we can obtain to important information related to our system: How stable our system is When the next failure will occur I think that the second point is pretty interesting, especially when we have a system in production. Theoretically, MTBF could tell to the operational and maintenance team when next fail over will have – in this way they can be prepared for it. MTBF can be calculated in different ways, the most simple formulate for it is the sum of all the time intervals when the system didn’t had a...

This is a blog post dedicated for people that are working with Exchange Web Server Library (EWS). This is wrapper over EWS API that gives the possibility to a developer to interrogate and communicate with an Exchange Server. When we are loading the list of emails from a folder we would have the following code: ExchangeService service = ... string folderId = ... ItemView itemView = ... Folder folder = Folder .Bind(service, new FolderId(folderId)); FindItemsResults<Item> items = folder .FindItems(searchFilter, itemView); We get a list of ‘Item’ that we can manipulate by us. It is very easy to extract different email details like ‘Subject’, ‘Id’ or ‘SentDate’. This solution will works for 99% or the cases, except one. When we want to load the items from ‘Draft’ folder. Surprise, we don’t have the ‘SentDate’ set. Of course this is normal, but EWS library will throw an ugly exception. Item item = ... DateTime sentDate = item.DateTimeSent; What should we do for this case? We...

Today we had CodeCamp in Sibiu . It was a great event, where more than 80 people attended to our sessions. This was a great event, where people were very interested about technologies that were presented during this sessions: code metrics, HTML5, SignalR, Knockout.js, virtualization, Hyper-V, System Center 2012R, cloud, private cloud (using Azure Pack) were discussed during the sessions. At this event I spoke about code metrics and how we can monitor and use them using Sonar. This event was organized by  CodeCamp  and  ITSpark  and was sustained by  iQuest Group  and  Microsoft Romania . Thank you for that. Pictures from event:

Yesterday we had our first CodeCamp in Brasov . It was a great event, where more than 80 people attended our sessions. Even if it was our first event organized in Brasov in the last 3-4 years, people were very interested about the topics that were presented. We also had the opportunity to discover a little bit of Brasov history and the beauty of the old town. This is one of the most beautiful city from Romania and has great and smart people. This event was organized by CodeCamp and ITSpark and was sustained by iQuest Group and Microsoft Romania . Thank you for that. From each community(CodeCamp and ITSpark) there were 2 and 1 MVPs (3 in total) that talked about the latest technologies and trends that are now on the market. Subjects like code metrics, HTML5, SignalR, Knockout.js, virtualization, Hyper-V, System Center 2012R, cloud, private cloud were discussed during the sessions. Brasov, see you next time!

What an event! Today we had Winter CodeCamp in Cluj-Napoca, where over 130 people participate to it. This special event was organized by CodeCamp Romania and ITSpark . From each community there were 2 MVPs (4 in total) that talked about the latest technologies and trends that are now on the market. Subject like code metrics, HTML5, SignalR, Knockout.js, virtualization, Hyper-V, System Center 2012R, cloud, private cloud (using Azure Pack) were discussed during the sessions. If you missed this event, is not to late, you can come in Brasov or Sibiu next week to our sessions:      Sibiu -   https://codecamp-sibiu-ian2014.eventbrite.com      Brasov -   https://codecamp-brasov-ian2014.eventbrite.com Special thanks to our sponsors, which made this great event possible: At this event I talked about software metrics, Sonar and how we can manage the quality of the code base on metrics.
