  • Advice for a getting a job in algorithmic trading - writing faster code

    - by Alex
    I am currently an intermediate Java developer working in the financial industry. I am considering trying to get into an algorithmic trading developer position. I am looking for any advice/resources that may help me obtain such a job. My naive initial thoughts are to concentrate on learning how to write faster, more memory efficient code whilst maintaining readability. Can anyone point me in the right direction of some useful resources for what I am aiming to achieve?

  • When does 'optimizing code' == 'structuring data'?

    - by NewAlexandria
    A recent article by ycombinator lists a comment with principles of a great programmer. #7. Good programmer: I optimize code. Better programmer: I structure data. Best programmer: What's the difference? Acknowledging subjective and contentious concepts - does anyone have a position on what this means? I do, but I'd like to edit this question later with my thoughts so-as not to predispose the answers.

  • How to have many Ubuntu workstations centrally managed?

    - by Richard Zak
    I have about a dozen Alienware workstations that are used for CUDA development and for execution of MPI jobs. What is the best way to manage them? I'd like to have something like an apt-get but for several systems, and a way to reimage a system simply and centrally. It seems that a combination of Landscape and Canonical's MAAS would be a good fit, but I need an open source solution. Any thoughts?

  • Should code comments have scope?

    - by Rig Veda
    I am asking this because I have seen places where, whoever coded initially had provided proper comments, but later on modifications were made to the code but the comments were left untouched. I remember reading somewhere " Don't get suckered in by the comments, debug only code". So is it a good/ relevant/ practical idea that tells the scope of the comments so as to prompt the developer for editing the comment. Your thoughts.

  • What makes a great place to work

    - by Rob Farley
    Co-incidentally, I’ve been looking for office space for LobsterPot Solutions during the same few days that Luke Hayler ( @lukehayler ) has asked for my thoughts (okay, he ‘tagged’ me) on what makes a great place to work . He lists People and Environment, and I’m inclined to agree, but with a couple of other things too. I have three children. Two of them (both boys) are in school, but my daughter is only two. For the boys’ schools, we quickly realised that what they need most is a feeling of safety...(read more)

  • Games at Work Part 2: Gamification and Enterprise Applications

    - by ultan o'broin
    Gamification and Enterprise Applications In part 1 of this article, we explored why people are motivated to play games so much. Now, let's think about what that means for Oracle applications user experience. (Even the coffee is gamified. Acknowledgement @noelruane. Check out the Guardian article Dublin's Frothing with Tech Fever. Game development is big business in Ireland too.) Applying game dynamics (gamification) effectively in the enterprise applications space to reflect business objectives is now a hot user experience topic. Consider, for example, how such dynamics could solve applications users’ problems such as: Becoming familiar or expert with an application or process Building loyalty, customer satisfaction, and branding relationships Collaborating effectively and populating content in the community Completing tasks or solving problems on time Encouraging teamwork to achieve goals Improving data accuracy and completeness of entry Locating and managing the correct resources or information Managing changes and exceptions Setting and reaching targets, quotas, or objectives Games’ Incentives, Motivation, and Behavior I asked Julian Orr, Senior Usability Engineer, in the Oracle Fusion Applications CRM User Experience (UX) team for his thoughts on what potential gamification might offer Oracle Fusion Applications. Julian pointed to the powerful incentives offered by games as the starting place: “The biggest potential for gamification in enterprise apps is as an intrinsic motivator. Mechanisms include fun, social interaction, teamwork, primal wiring, adrenaline, financial, closed-loop feedback, locus of control, flow state, and so on. But we need to know what works best for a given work situation.” For example, in CRM service applications, we might look at the motivations of typical service applications users (see figure 1) and then determine how we can 'gamify' these motivations with techniques to optimize the desired work behavior for the role (see figure 2). Description of Figure 1 Description of Figure 2 Involving Our Users Online game players are skilled collaborators as well as problem solvers. Erika Webb (@erikanollwebb), Oracle Fusion Applications UX Manager, has run gamification events for Oracle, including one on collaboration and gamification in Oracle online communities that involved Oracle customers and partners. Read more... However, let’s be clear: gamifying a user interface that’s poorly designed is merely putting the lipstick of gamification on the pig of work. Gamification cannot replace good design and killer content based on understanding how applications users really work and what motivates them. So, Let the Games Begin! Gamification has tremendous potential for the enterprise application user experience. The Oracle Fusion Applications UX team is innovating fast and hard in this area, researching with our users how gamification can make work more satisfying and enterprises more productive. If you’re interested in knowing more about our gamification research, sign up for more information or check out how your company can get involved through the Oracle Usability Advisory Board.

  • Naming methods that perform HTTP GET/POST calls?

    - by antonpug
    In the application I am currently working on, there are generally 3 types of HTTP calls: pure GETs pure POSTs (updating the model with new data) "GET" POSTs (posting down an object to get some data back, no updates to the model) In the integration service, generally we name methods that post "postSomething()", and methods that get, "getSomething()". So my question is, if we have a "GET" POST, should the method be called: getSomething - seeing as the purpose is to obtain data postSomething - since we are technically using POST performSomeAction - arbitrary name that's more relevant to the action What are everyone's thoughts?

  • htaccess rewrite doesn't work

    - by Raimond van Mouche
    I'm trying to redirect url's in my /joomla/ folder containing "rsform" to the same url but except for /joomla/ /formulieren/. However my tried .htaccess rewrite doesn't work. I tried: RewriteEngine on RewriteCond %{REQUEST_URI} rsform RewriteRule ^(.+)$ http://watervriendengeleen.nl/joomla/ [L,R=301] And other URL related rewrites like Redirect /joomla/index.php?option=com_rsform&formId=12&Itemid=99999 http://sitename.com/formulieren/index.php?option=com_rsform&formId=12&Itemid=99999 which didn't work either. Any thoughts?

  • The Use-Case Driven Approach to Change Management

    - by Lauren Clark
    In the third entry of the series on OUM and PMI’s Pulse of the Profession, we took a look at the continued importance of change management and risk management. The topic of change management and OUM’s use-case driven approach has come up in few recent conversations. So I thought I would jot down a few thoughts on how the use-case driven approach aids a project team in managing the project’s scope. The use-case model is one of several tools in OUM that is used to establish and manage the project's scope.  Because a use-case model can be understood by both business and IT project team members, it can serve as a bridge for ongoing collaboration as well as a visual diagram that encapsulates all agreed-upon functionality. This makes it a vital artifact in identifying changes to the project’s scope. Here are some of the primary benefits of using the use-case model as part of the effort for establishing and managing project scope: The use-case model quickly communicates scope in a straightforward manner. All project stakeholders can have a common foundation for the decisions regarding architecture and design and how they relate to the project's objectives. Once agreed upon, the model can be put under change control and any updates to the model can then be quickly identified as potentially affecting the project’s scope.  Changes requested or discovered later in the project can be analyzed objectively for their impact on project's budget, resources and schedule. A modular foundation for the design of the software solution can be established in Elaboration.  This permits work to be divided up effectively and executed in so that the most important and riskiest use-cases can be tackled early in the project. The use-case model helps the team make informed decisions about implementation priorities, which allows effective allocation of limited project resources.  This is very helpful in not only managing scope, but in doing iterative and incremental planning which relies heavily on the ability to identify project priorities. Bottom line is that the use-case model gives the project team solid understanding of scope early in the project.  Combine this understanding with effective project management and communication and you have an effective tool for reducing the risk of overruns in budget and/or time due to out of control scope changes. Now that you’ve had a chance to read these thoughts on the use-case model and project scope, please let me know your feedback based on your experience.

  • Outlook of XBAP technology [closed]

    - by Dan
    My company is debating releasing an application using XBAP deployment. Does anyone know the feasibility of this technology? It seems like it only exists in IE and there's been no new development talk from MS about it. It seems like most people are going Silverlight (though even that's being cut from what I can tell in favor of HTML5). What are your thoughts? I can't even seem to find anything about MS supporting it in IE10.

  • Using only password to authenticate user (no "username" field)

    - by Guy
    I am creating a client access system, to allow manage invoices, make payments, access information about their products and information/functionality alike. Supposedly there are less than 1000 clients. Would there be any security threat to use only password (UUID v4 strings) to authenticate user? My thoughts: There is virtually no probability of collision or success with brute-force attack. http://en.wikipedia.org/wiki/UUID#Random%5FUUID%5Fprobability%5Fof%5Fduplicates User friendly (one click go) It is not intended to be remembered
