    Without a doubt, jQuery has given a much needed boost to JavaScript, a language so useful but equally underrated at times. Before jQuery comes into picture, we used to write lengthy JavaScript code not just for bigger but even for smaller functionality. Those code were at times both difficult to read and maintain.

So what changed since 0.2.x? I ripped out the old nanite generator since the nanite project seems pretty much abandoned. It was initially added to help daemon-kit attract some mindshare in…
  • Reusing your frontend JS on the server with The Ruby Racer

    Kenneth Kalmer
    16 Apr 2013 | 5:00 pm
    I can’t tell you how much fun it is typing out a blog post again. It has been nearly two years since the last post. I hope this will be the end of the dry spell for me. Earlier this year at Rubyfuza 2013 I had the privilege to share with the audience how, at ValuationUP, we reuse our frontend JavaScript on the server side using The Ruby Racer, allowing us to push the SOLID principles to the max by crossing the language barrier using DI & IoC across the language barriers. The video and the slides are below for your enjoyment. The sample code lives at kennethkalmer/rubyfuza-2013, and the…

  • State Certification of Future Voting Systems — Three Points of Departure

    E. John Sebes
    2 Mar 2015 | 8:44 pm
    In advance of this week’s EVN Conference, we’ve been talking frequently with colleagues at several election oriented groups (Brennan Center, National Organization of State Legislatures, EAC, NIST, and others) about the way forward from the current voting system certification regime. One of the topics for the EVN conference is a shared goal for many of us: how to move toward a near future certfication regime that can much better serve state election officials in states that want to have more control, customization, and tailoring of the certification process, to better serve the…
  • Future of Voting Systems: Future Requirements (Part 1)

    E. John Sebes
    20 Feb 2015 | 12:44 pm
    For this first of several reports from the NIST/EAC Future of Voting Systems Symposium II, some readers of my recent report on standard work, may heave a sigh of relief that I’m not doing a long post that’s a laundry list of topics. However, I will be doing a series of posts on one part of the conference, a session held by some EAC who run the voting systems certification program, which relies on a “guidelines” document that is actually a complex set of standards that voting systems have to meet in order to get certified. The reason that I am doing a series of posts is…
  • Election Standards, Day 2

    E. John Sebes
    13 Feb 2015 | 5:45 pm
    The second day of the annual meeting of the Voting System Standards Committee was Friday Feb. 6. I’m concluding my reporting on the meeting with a round up of existing and proposed standards activity that we discussed on day 2. Each item below is about an existing working group, a group in formation, or proposed groups. Election Process Modeling This working group isn’t making a standard, but rather a guideline: a semi-formal model for the typical or common processes for U.S. election administration and election operations. The intent here is to document, in a structured manner,…
  • Election Standards – Part Two

    E. John Sebes
    7 Feb 2015 | 3:28 pm
    Last time I reported on the first segment of the annual meeting of the Voting Systems Standards Group (VSSC) of the IEEE. Most of that segment was about the soon-to-be-standard for election definition and election results (called VSSC.2). I recapped some of the benefits of data standards, using that as an example.  Much of the rest of day one was related to that standard in a number of ways. First, we got an update on the handful of major comments submitted during the earlier review periods, and provided input on how to resolve these finalize the standard document. Second, we reviewed…

    E. John Sebes
    4 Feb 2015 | 2:03 pm
    After a big push to reach 2014 milestones for several technology efforts, there’s much to catch up on here in the TTV technology blog, and some 2015 to keep abreast of. However, today I’ll start with a closely related topic — election data standards — because the annual meeting of the standards body is this week. We (principally myself, John Sebes) be reporting from this standards conference, but first its probably a good idea to refresh the readers’ memory about where standards fit in, and how important they are. I’ll do that explaining 4 benefits that are…

    Think about the Internet today. Websites and web services are in deep conversation with each other through the so-called API (Application Program Interface) economy. Websites such as Facebook, Weather.com, and ESPN all offer APIs that the rest of the cloud can leverage and interact with. Through this API economy, the exchange of data is free-flowing and massive. However, the only things that are taking part in this conversation are typically computers, laptops, and smartphones. What happens when other electronic devices can start to take part in this data exchange? read more

  • The three open source projects that transformed Hadoop

    JBuckley
    4 Mar 2015 | 4:00 am
    Hadoop, an open source software framework with the funny sounding name, has been a game-changer for organizations by allowing them to store, manage, and analyze massive amounts of data for actionable insights and competitive advantage. But this wasn't always the case. Initially, Hadoop implementation required skilled teams of engineers and data scientists, making Hadoop too costly and cumbersome for many organizations. Now, thanks to a number of open source projects, big data analytics with Hadoop has become much more affordable and mainstream. Here's a look at how three open source…

  • How to Read File in One Line in JDK 7 or Java 8

    Javin Paul
    24 Feb 2015 | 7:34 am
    Reading a file in Java is not simple, it requires lots of boiler plate code, as we have seen in our earlier example of reading text files. Various things had to wrapped e.g. a FileInputStream inside a BufferedReader, loops with weird terminating conditions had to be specified and so forth. From JDK 7 onward,  you can do a lot better. It provides lots of useful classes e.g. Files and Paths to deal with file and their actual path. In this article, we will see how we can read a file in just one line. Of course, your production code won't be like that, especially if you are reading a few…

    Javin Paul
    23 Feb 2015 | 6:14 am
    Without a doubt, jQuery has given a much needed boost to JavaScript, a language so useful but equally underrated at times. Before jQuery comes into picture, we used to write lengthy JavaScript code not just for bigger but even for smaller functionality. Those code were at times both difficult to read and maintain. Having written JavaScript before using this excellent library, I realized true power of jQuery, just after using it for a month. Given it's huge popularity, jQuery interview questions are increasingly asked in any web developer interview, not just beginners but also experienced…
  • How to disable JUnit Test - @Ignore annotation Example

    Javin Paul
    18 Feb 2015 | 4:36 am
    If you are using JUnit 4, then you can use @Ignore annotation to disable a test case; what this means is that, any method which is annotated by @Ignore, will not be executed by JUnit. Why would you want to disable a test? Well, It may be because that particular test is for a functionality which is not yet implemented fully and because of that your build is failing. Like that there could be some other scenarios where you would like to temporarily disable a test or a group of tests. From JUnit 4 onward test methods are annotated with @Test, so if they are also annotated with @Ignore will not…
  • Difference between UTF-8, UTF-16 and UTF-32 Character Encoding

    Javin Paul
    17 Feb 2015 | 5:33 am
    Main difference between UTF-8, UTF-16 and UTF-32 character encoding is how many bytes it require to represent a character in memory. UTF-8 uses minimum one byte, while UTF-16 uses minimum 2 bytes. BTW, if character's code point is greater than 127, maximum value of byte then UTF-8 may take 2, 3 o 4 bytes but UTF-16 will only take either two or four bytes. On the other hand, UTF-32 is fixed width encoding scheme and always uses 4 bytes to encode a Unicode code point. Now, let's start with what is character encoding and why it's important? Well, character encoding is an important…

    Service agility keeps an organisation ahead of its competitors, but it depends on an agile IT infrastructure that can keep pace.   An agile business demands a lot from their IT department. There are two ways of dealing with these requests - which camp do you want to be in? Typical agile business demands: Marketing need to process several TB of big data. Sales need a new eCommerce platform. Your Developers are A/B testing a new website design. Your new CRM system needs more data storage. Your new online billing system needs secure payments processing. You need a nationwide stock…
  • What Are the Benefits of Partnering with an MSP?

    26 Feb 2015 | 2:00 am
    Using a Managed Service Provider (MSP) will keep your IT up to date and ready for whatever challenges your organisation faces in future. Read on to find out about the benefits of MSPs. 'Asset Light' is business jargon that means what the MBA using it wants it to mean. In manufacturing it's a strategy used to eliminate fixed costs by outsourcing production. (Like Apple do - but no-one describes them as asset light!) It's better applied to departments within an organisation - if your IT department is asset light the cash that would have been spent buying and running hardware, building and…
  • The Dangers of Shadow IT

    Simon Mitchell
    19 Feb 2015 | 2:00 am
    Shadow IT can be a force for good driving innovation and enabling business agility, but unregulated IT projects can be expensive and dangerous. Shadow IT projects often arise from good intentions: Sometimes people in the IT department sneak new technology into the company without board approval. This is how Linux established itself in many server rooms 20 years ago. Sometimes other departments set up shadow IT projects, often using public Cloud facilities, without getting the IT department on board. But even projects begun with the best intentions can have unintended…

  • What Is an MSP and How Do I Choose One?

    Simon Mitchell
    5 Feb 2015 | 2:00 am
    Using a Managed Service Provider (MSP) isn't the same as outsourcing your entire IT operation, but it’s essential you choose wisely. What is an MSP? A Managed Service Provider is a team of experts (in this case Linux systems management experts) who provide defined services to an enterprise whilst overall accountability of your service remains with the enterprise's own team. MSPs are often used to provide expertise in new technologies or when an enterprise needs to change its hardware, software or methods whilst maintaining business continuity.
