Programmers and developers have been anxiously waiting for an invite into the Docker application beta since earlier this year. During their announcement video, Docker shared that they had over 30,000 interested parties sign up within hours of the initial announcement. A grand total of 70,000 were able to join the beta to provide feedback and get a hands-on experience with the application. But for those that haven’t gotten in, today they can do so with the open beta announced for Docker on Mac and Windows. The Docker platform is one…

ASP.NET LinkButton: children disappears after postback

Enrico

I have a LinkButton with image and label inside it or tags i and span as in the following picture. The code in the page is: <asp:LinkButton ID="LinkButton1" runat="server"> <i class="glyphicon glyphicon-plus"></i> <span class="js-add-button" runat="server" id="Span1">Add New</span> </asp:LinkButton> After a postback everything inside the LinkButton disappeared. I’ve spent two days to understand why and the solution is very easy. <asp:LinkButton ID="LinkButton1" runat="server"> <i class="glyphicon glyphicon-plus" runat="server"></i> <span class="js-add-button" runat="server" id="Span1">Add New</span> </asp:LinkButton> The tag i doesn’t have runat="server" and for that you lost all content inside the LinkButton. Happy coding!

Microsoft takes on IFTTT with Flow

Enrico

IFTTT is one of the most useful online services. Today, Microsoft is taking on IFTTT with its new service called “Flow”. The company is launching the preview of Flow today, and it works almost like IFTTT. Unlike IFTTT, Flow isn’t mostly focused on consumers — instead, it’s mostly focused on enterprise integrations. Flow lets you automate your workflow, and be more productive. With Flow, you can setup GitHub to automatically send a Slack notification and add a card in Trello when a new issue is submitted. Additionally, you can also…

Under the hood of Microsoft’s Windows Subsystem for Linux

Enrico

Bash on Windows 10 was one of the big reveals at Microsoft’s recent Build conference. Since then, there’s been a lot of speculation about what Microsoft did to make this possible. Microsoft is starting to provide more details via blog posts and a new Channel 9 video on what’s going on under the covers. Spoiler alert: There’s no secret Linux kernel hidden in Windows 10. Instead, it’s the Windows Subsystem for Linux (WSL) that was developed by the Windows Kernel team is what provides the foundation that enabled the Linux…

C# 7 Features Previewed

Enrico

Over the last year we’ve shown you various features that were being considered for C# 7. With the preview of Visual Studio 15, Microsoft has decided to demonstrate the features to make it into the final release of C# 7. Tuple Value Types .NET has a tuple type, but in the context of C# there are a lot of problems. Being a reference type, you probably want to avoid using it in performance sensitive code as you have to pay for GC costs. And as they are immutable, while making…

Data and data access technologies

Enrico

In my previous post I spoke about key layers of distributed applications. Now we will go through the most crucial layer of any distributed application, the data layer. In this part, you will be introduced to various database technologies, along with .NET-related technologies. Data can be stored in a wide range of data sources such as relational databases, files on the local filesystems, on the distributed filesystems, in a caching system, in storage located on the cloud, and in memory. Relational databases (SQL server): This is the traditional data source…

Key layers of distributed applications

Enrico

Every application that is going to be used by end users should be designed appropriately as users are expecting to process information from various data sources that might be geographically distributed. They are also expecting this information to be up-to-date and capable of being inflected very fast. Designing such applications is not an easy task and involves integration among different groups of components. Let’s review the layers that form a typical distributed application. The responsibilities in a distributed system can be divided into four layers: The data layer The business…

Enrico

In the world of the Internet, technology is constantly changing. The SMTP technology behind email, however, has not changed much since it was first released a very long time ago. Despite the invention of SMTP SMARTTM to solve this problem, most emails are still unencrypted, and thus open to a man in the middle hack. Luckily though, a team of engineers from Microsoft, Google, Yahoo, Comcast, and other leading companies have been working on a proposal which would cut out the middle man hacker The proposal which has been submitted…

275 million Android phones imperiled by new code-execution exploit

Enrico

Almost 300 million phones running Google’s Android operating system are vulnerable to a newly developed drive-by attack that can install malware and take control of key operations, a security firm has warned.

Microsoft adds ‘non-security updates’ to security patches

Enrico

MS16-023, billed as a “Security update for Internet Explorer” and issued on March 8, includes six “General distribution release (GDR) fixes”. Five are innocuous as they address glitches like “Empty textarea loses its closing tag in Internet Explorer 11 after conversion from XML to HTML.” But the last item on the list item 3146449, has the rather more interesting title “Updated Internet Explorer 11 capabilities to upgrade Windows 8.1 and Windows 7.” A great many users just accept all Windows updates, so will never see item 3146449. Even if you…

Microsoft has released a Debian Linux switch OS

Enrico

Put down your coffee gently. Microsoft has today released a homegrown open-source operating system, based on Debian GNU/Linux, that runs on network switches. The software is dubbed SONiC, aka Software for Open Networking in the Cloud. It’s a toolkit of code and kernel patches to bend switch hardware to your will, so you can dictate how it works and what it can do, rather than relying on proprietary firmware from a traditional networking vendor. It also pits Redmond against white-box network operating systems from the likes of HP, Dell, and…

Microsoft now plans March Windows 10 Mobile rollout

Enrico

February has come and gone without the highly anticipated Windows 10 Mobile upgrade for legacy Lumia handsets. In an email to partners, seen by VentureBeat, Microsoft is now targeting a release this month, to occur after the regular monthly service updates for the two Windows 10-powered handsets already on the market, the Lumia 950 and 950 XL.
