Nick Van Hoogenstyn spoke about HackerRank, a tool for testing programmers. Common uses are

  1. Screening of job candidates
  2. Resource when holding hackathons
  3. Training tool to evaluate the learning of skills

Nick described three products

  1. HackerRank.com – openly available to all for coding challenges and timed contests with prizes
  2. HackerRank for Work – paid candidate assessment program.
    1. Questions can be send to candidates for their completion
    2. A collaborative coding session allows interviewers to see how candidates solve questions
  3. HackerRank Jobs – mobile app that developers use to prove their skills (automatically generates a score and gives feedback)

Nick then walked through a series of problems that a candidate might face. He then talked about the measures that an interviewer/evaluator can use

  1. A plagiarism flag for suspicious code
  2. A slider to replay the individual keystrokes
  3. Execution time and memory used by the completed program
  4. Breakdown on time spent on each question

He talked about how questions can be taken from a library or can be custom generated. The evaluator can select the programming language(s) that the candidate can use.

Roderick Thomas @Pershing spoke about his company’s techniques to customize the look and feel of a web site for a standard set of building blocks. The goal is to create different themes for a common back end or permit plug-ins or moves to an alien #web page while maintaining a seamless experience.

One of the biggest challenges for traditional financial advisers is their aging clientele and their inability to attract younger clients. Building a new set of tools with a different look and feel is one way to appeal to younger potential clients: simplify, multiple platforms, empower self-serve, collaboration, etc.

Roderick talked about how #components (= web #widget bound to data) can be customized using css from responsive designs done in concert with the server (not just client side).

Integration tools include

  1. Web components – suite of W3C specs: custom elements, shadow dom, templates; but limited adoptions – only evergreen browsers (not IE and not Safari), for Chrome and Firefox. Instead use doJo to cover more browsers.
  2. Polymer/ react / angular/… – alternative to web components. React – limited to the view: virtual dom – does a diff so it does not need to rewrite the entire page. Angular – complete framework – similar to components but does not integrate with other solutions.
  3. Open F2 – open financial framework – sponsored by Yahoo, TD, RBC, etc. and others in finance. Designed so components from multiple financial vendors mesh together.

Technical strategy adopted

  1. Dynamic page layouts & Themes – provide an alternative look and feel (like WordPress themes).
    1. Started with a conservative theme for older clients.
    2. then brought out ADA for government clients – designed for those with disabilities.
    3. Now working on theme for the millennials – everything is displayed and you scroll down for more content (ala Facebook).
    4. Eventually will have a HNW theme showing financial data differently.
  2. Branding – private label offerings. Moving from page to page on a web site, you may navigate to different vendors, but the look and feel remains the same. Use CSS to get color scheme and behavior.
  3. Omni channel support – pc, tablet, phone, tv,…

They use the html5 spec for all development.

Examples of different looks for the same data

conventional (conservative) look
