  • What is a typical scenario for and end-user reports design?

    - by Sebastian
    Hello! I'm wondering what would be the typical scenario for using an end-user report designer. What I'm thinking of is to have a base report with all the columns that I can have, also with a basic view of the report (formatting, order of columns, etc.) and then let the user to change that format and order, take out or add (from the available columns) data to it, etc. Is that a common way to address what is called end-user designer for reports or I'm off track? I know it depends on the user (if it's someone that can handle SQL or not for example), but is it common to have a scenario where the user can build everthing from the sql query to the formatting? Thanks! Sebastian

  • Oracle Tutor: Installing Is Not Implementing or Why CIO's should care about End User Adoption

    - by emily.chorba(at)oracle.com
    Eighteen months ago I showed Tutor and UPK Productive Day One overview to a CIO friend of mine. He works in a manufacturing business which had been recently purchased by a global conglomerate. He had a major implementation coming up, but said that the corporate team would be coming in to handle the project. I asked about their end user training approach, but it was unclear to him at the time. We were in touch over the course of the implementation project. The major activities were data conversion, how-to workshops, General Ledger realignment, and report definition. The message was "Here's how we do it at corporate, and here's how you are going to do it." In short, it was an application software installation. The corporate team had experience and confidence and the effort through go-live was smooth. Some weeks after cutover, problems with customer orders began to surface. Orders could not be fulfilled in a timely fashion. The problem got worse, and the corporate emergency team was called in. After many days of analysis, the issue was tracked down and resolved, but by then there were weeks of backorders, and their customer base was impacted in a significant way. It took three months of constant handholding of customers by the sales force for good will to be reestablished, and this itself diminished a new product sales push. I learned of these results in a recent conversation with the CIO. I asked him what the solution to the problem was, and he replied that it was twofold. The first component was a lack of understanding by customer service reps about how a particular data item in order entry was to be filled in, resulting in discrepant order data. The second component was that product planners were using this data, along with data from other sources, to fill in a spreadsheet based on the abandoned system. This spreadsheet was the primary input for planning data. The result of these two inaccuracies was that key parts were not being ordered to effectively meet demand and the lead time for finished goods was pushed out by weeks. I reminded him about the Productive Day One approach, and it's focus on methodology and tools for end user training. A more collaborative solution workshop would have identified proper applications use in the new environment. Using UPK to document correct transaction entry would have provided effective guidelines to the CSRs for data entry. Using Oracle Tutor to document the manual tasks would have eliminated the use of an out of date spreadsheet. As we talked this over, he said, "I wish I knew when I started what I know now." Effective end user adoption is the most critical and most overlooked success factor in applications implementations. When the switch is thrown at go-live, employees need to know how to use the new systems to do their jobs. Their jobs are made up of manual steps and systems steps which must be performed in the right order for the implementing organization to operate smoothly. Use Tutor to document the manual policies and procedures, use UPK to document the systems tasks, and develop this documentation in conjunction with a solution workshop. This is the path to develop effective end user training material for a smooth implementation. Learn More For more information about Tutor, visit Oracle.com or the Tutor Blog.

  • Is using Javascript/JQuery for layout and style bad practice?

    - by Renesis
    Many, but not all, HTML layout problems can be solved with CSS alone. For those that can't, JQuery (on document load) has become very popular.* As a result of its ease, many developers are quick to use JQuery or Javascript for layout and style — even without understanding whether or not the problem can be solved with CSS alone. This is illustrated by responses to questions like this one. Is this bad practice? What are the arguments for/against? Should someone who sees this in practice attempt to persuade those developers otherwise? If so, what are the best responses to arguments in favor of JQuery saying it's "so easy"? * Example: Layouts that wish to use vertical layout flow of some kind often run into dead ends with CSS alone — this would include layouts similar to Pinterest, though I'm not sure that's actually impossible with CSS.

  • Installing Ubuntu 12.10 on Mac Mini (End 2009)

    - by Till Lange
    I am trying to installing Ubuntu 12.10 on my Mac Mini (End 2009). This sounds like a often asked question and I all ready read lots of stuff about it, but now I am confused. While some people say, there are heavy problems by installing Ubuntu on a Mac Mini, such as components (like Sound card, graphic card, …) don't work very well, others say, that it should work perfectly fine. I figured out that installing UBNTU on a Mac isn't as easy (can't just downld the .iso and use unetboot, …) as it is on a PC. So, is it possible to install Ubuntu 12.10 on a Mac Mini 2009 (end), so everything works well?

  • Mod_rewrite and urls that don't end with .php

    - by Kevin Laity
    I'm trying to use Mod_rewrite to hide the .php extensions of my pages. However, it refuses to do any rewriting unless the input url ends with .php, which makes that impossible. I can confirm that rewriting works fine as long as the url has .php at the end. RewriteRule a\.php b\.php Works, while RewriteRule a\.html b\.html does not. How can I turn off this behavior and allow it to rewrite all urls? I'm on a shared host so whatever I do has to be done from a .htaccess file. Update: There seems to be some confusion about what I'm asking here. The question is not about how to write the rule, the question is about server configuration. The rule I'm using is fine, I can test that locally. But the server I'm working with is somehow configured so that mod_rewrite doesn't attempt to rewrite anything that doesn't end with .php

    - by user1769787
    I am doing work in asp.net (mvc) in my starting days of programming 2 years ago.I have done work on some web-apps. I am not comfortable with c# but have working skill in jQuery and front-end development. from a year I do UI kind of work. Now someone can suggest me what should I do for next. Should I learn asp.net mvc or I should go for PHP then I can do some wordpress development. The problem is I never found small people use asp.net rather then PHP.( I am not currently employed). Someone can help me what should I do. I have front-end skill (not in programming) so what Is best for me to do.

  • All around design book for a developer (Javascript dev)

    - by Alex Angelini
    I have begun doing a lot of javascript development recently, mostly front-end but also using node.js. As I am currently in the transition from large company to startup, they expect me as a front end developer to know how to produce semi decent designs (Which I cannot) I am looking for a book (or set of screencasts) to give me some good well rounded advice on design. I know CSS, but my design are always awful looking, I also know nothing about Photoshop (and am on Linux and have no access to it) What are your picks? I am not looking to be a full time designer I would just like to be able to contribute.

  • Switch from back-end to front-end programming: I'm out of my comfort zone, should I switch back?

    - by ripper234
    I've been a backend developer for a long time, and I really swim in that field. C++/C#/Java, databases, NoSql, caching - I feel very much at ease around these platforms/concepts. In the past few years, I started to taste end-to-end web programming, and recently I decided to take a job offer in a front end team developing a large, complex product. I wanted to break out of my comfort zone and become more of an "all around developer". Problem is, I'm getting more and more convinced I don't like it. Things I like about backend programming, and missing in frontend stuff: More interesting problems - When I compare designing a server that handle massive data, to adding another form to a page or changing the validation logic, I find the former a lot more interesting. Refactoring refactoring refactoring - I am addicted to Visual Studio with Resharper, or IntelliJ. I feel very comfortable writing code as it goes without investing too much thought, because I know that with a few clicks I can refactor it into beautiful code. To my knowledge, this doesn't exist at all in javascript. Intellisense and navigation - I hate looking at a bunch of JS code without instantly being able to know what it does. In VS/IntelliJ I can summon the documentation, navigate to the code, climb up inheritance hiererchies ... life is sweet. Auto-completion - Just hit Ctrl-Space on an object to see what you can do with it. Easier to test - With almost any backend feature, I can use TDD to capture the requirements, see a bunch of failing tests, then implement, knowing that if the tests pass I did my job well. With frontend, while tests can help a bit, I find that most of the testing is still manual - fire up that browser and verify the site didn't break. I miss that feeling of "A green CI means everything is well with the world." Now, I've only seriously practiced frontend development for about two months now, so this might seem premature ... but I'm getting a nagging feeling that I should abandon this quest and return to my comfort zone, because, well, it's so comfy and fun. Another point worth mentioning in this context is that while I am learning some frontend tools, a lot of what I'm learning is our company's specific infrastructure, which I'm not sure will be very useful later on in my career. Any suggestions or tips? Do you think I should give frontend programming "a proper chance" of at least six to twelve months before calling it quits? Could all my pains be growing pains, and will they magically disappear as I get more experienced? Or is gaining this perspective is valuable enough, even if plan to do more "backend stuff" later on, that it's worth grinding my teeth and continuing with my learning?

  • Delphi Editbox causing unexplainable errors...

    - by NeoNMD
    On a form I have 8 edit boxes that I do the exact same thing with. They are arranged in 2 sets of 4, one is Upper and the other is Lower. I kept getting errors clearing all the edit boxes so I went through clearing them 1 by 1 and found that 1 of the edit boxes just didnt work and when I tried to run the program and change that exit box it caused the debugger to jump to a point in the code with the database (even though the edit boxes had nothing to do with the database and they arent in a procedure or stack with a database in it) and say the program has access violation there. So I then removed all mention of that edit box and the code worked perfectly again, so I deleted that edit box, copied and pasted another edit box and left all values the same, then went through my code and copied the code from the other sections and simply renamed it for the new Edit box and it STILL causes an error even though it is entirely new. I cannot figure it out so I ask you all, what the hell?

  • Front-end structure of large scale Django project

    - by Saike
    Few days ago, I started to work in new company. Before me, all front-end and backend code was written by one man (oh my...). As you know, Django app contains two main directories for front-end: /static - for static(public) files and /templates - for django templates Now, we have large application with more than 10 different modules like: home, admin, spanel, mobile etc. This is current structure of files and directories: FIRST - /static directory. As u can see, it is mixed directories with some named like modules, some contains global libs. one more: SECOND - /templates directory. Some directories named like module with mixed templates, some depends on new version =), some used only in module, but placed globally. and more: I think, that this is ugly, non-maintable, put-in-stress structure! After some time spend, i suggest to use this scheme, that based on module-structure. At first, we have version directories, used for save full project backup, includes: /DEPRECATED directory - for old, unused files and /CURRENT (Active) directory, that contains production version of project. I think it's right, because we can access to older or newer version files fast and easy. Also, we are saved from broken or wrong dependencies between different versions. Second, in every version we have standalone modules and global module. Every module contains own /static and /templates directories. This structure used to avoid broken or wrong dependencies between different modules, because every module has own js app, css tables and local images. Global module contains all libraries, main stylesheets and images like logos or favicon. I think, this structure is much better to maintain, update, refactoring etc. My question is: How do you think, is this scheme better than current? Can this scheme live, or it is not possible to implement this in Django app?

  • Refactoring a Single Rails Model with large methods & long join queries trying to do everything

    - by Kelseydh
    I have a working Ruby on Rails Model that I suspect is inefficient, hard to maintain, and full of unnecessary SQL join queries. I want to optimize and refactor this Model (Quiz.rb) to comply with Rails best practices, but I'm not sure how I should do it. The Rails app is a game that has Missions with many Stages. Users complete Stages by answering Questions that have correct or incorrect Answers. When a User tries to complete a stage by answering questions, the User gets a Quiz entry with many Attempts. Each Attempt records an Answer submitted for that Question within the Stage. A user completes a stage or mission by getting every Attempt correct, and their progress is tracked by adding a new entry to the UserMission & UserStage join tables. All of these features work, but unfortunately the Quiz.rb Model has been twisted to handle almost all of it exclusively. The callbacks began at 'Quiz.rb', and because I wasn't sure how to leave the Quiz Model during a multi-model update, I resorted to using Rails Console to have the @quiz instance variable via self.some_method do all the heavy lifting to retrieve every data value for the game's business logic; resulting in large extended join queries that "dance" all around the Database schema. The Quiz.rb Model that Smells: class Quiz < ActiveRecord::Base belongs_to :user has_many :attempts, dependent: :destroy before_save :check_answer before_save :update_user_mission_and_stage accepts_nested_attributes_for :attempts, :reject_if => lambda { |a| a[:answer_id].blank? }, :allow_destroy => true #Checks every answer within each quiz, adding +1 for each correct answer #within a stage quiz, and -1 for each incorrect answer def check_answer stage_score = 0 self.attempts.each do |attempt| if attempt.answer.correct? == true stage_score += 1 elsif attempt.answer.correct == false stage_score - 1 end end stage_score end def winner return true end def update_user_mission_and_stage ####### #Step 1: Checks if UserMission exists, finds or creates one. #if no UserMission for the current mission exists, creates a new UserMission if self.user_has_mission? == false @user_mission = UserMission.new(user_id: self.user.id, mission_id: self.current_stage.mission_id, available: true) @user_mission.save else @user_mission = self.find_user_mission end ####### #Step 2: Checks if current UserStage exists, stops if true to prevent duplicate entry if self.user_has_stage? @user_mission.save return true else ####### ##Step 3: if step 2 returns false: ##Initiates UserStage creation instructions #checks for winner (winner actions need to be defined) if they complete last stage of last mission for a given orientation if self.passed? && self.is_last_stage? && self.is_last_mission? create_user_stage_and_update_user_mission self.winner #NOTE: The rest are the same, but specify conditions that are available to add badges or other actions upon those conditions occurring: ##if user completes first stage of a mission elsif self.passed? && self.is_first_stage? && self.is_first_mission? create_user_stage_and_update_user_mission #creates user badge for finishing first stage of first mission self.user.add_badge(5) self.user.activity_logs.create(description: "granted first-stage badge", type_event: "badge", value: "first-stage") #If user completes last stage of a given mission, creates a new UserMission elsif self.passed? && self.is_last_stage? && self.is_first_mission? create_user_stage_and_update_user_mission #creates user badge for finishing first mission self.user.add_badge(6) self.user.activity_logs.create(description: "granted first-mission badge", type_event: "badge", value: "first-mission") elsif self.passed? create_user_stage_and_update_user_mission else self.passed? == false return true end end end #Creates a new UserStage record in the database for a successful Quiz question passing def create_user_stage_and_update_user_mission @nu_stage = @user_mission.user_stages.new(user_id: self.user.id, stage_id: self.current_stage.id) @nu_stage.save @user_mission.save self.user.add_points(50) end #Boolean that defines passing a stage as answering every question in that stage correct def passed? self.check_answer >= self.number_of_questions end #Returns the number of questions asked for that stage's quiz def number_of_questions self.attempts.first.answer.question.stage.questions.count end #Returns the current_stage for the Quiz, routing through 1st attempt in that Quiz def current_stage self.attempts.first.answer.question.stage end #Gives back the position of the stage relative to its mission. def stage_position self.attempts.first.answer.question.stage.position end #will find the user_mission for the current user and stage if it exists def find_user_mission self.user.user_missions.find_by_mission_id(self.current_stage.mission_id) end #Returns true if quiz was for the last stage within that mission #helpful for triggering actions related to a user completing a mission def is_last_stage? self.stage_position == self.current_stage.mission.stages.last.position end #Returns true if quiz was for the first stage within that mission #helpful for triggering actions related to a user completing a mission def is_first_stage? self.stage_position == self.current_stage.mission.stages_ordered.first.position end #Returns true if current user has a UserMission for the current stage def user_has_mission? self.user.missions.ids.include?(self.current_stage.mission.id) end #Returns true if current user has a UserStage for the current stage def user_has_stage? self.user.stages.include?(self.current_stage) end #Returns true if current user is on the last mission based on position within a given orientation def is_first_mission? self.user.missions.first.orientation.missions.by_position.first.position == self.current_stage.mission.position end #Returns true if current user is on the first stage & mission of a given orientation def is_last_mission? self.user.missions.first.orientation.missions.by_position.last.position == self.current_stage.mission.position end end My Question Currently my Rails server takes roughly 500ms to 1 sec to process single @quiz.save action. I am confident that the slowness here is due to sloppy code, not bad Database ERD design. What does a better solution look like? And specifically: Should I use join queries to retrieve values like I did here, or is it better to instantiate new objects within the model instead? Or am I missing a better solution? How should update_user_mission_and_stage be refactored to follow best practices? Relevant Code for Reference: quizzes_controller.rb w/ Controller Route Initiating Callback: class QuizzesController < ApplicationController before_action :find_stage_and_mission before_action :find_orientation before_action :find_question def show end def create @user = current_user @quiz = current_user.quizzes.new(quiz_params) if @quiz.save if @quiz.passed? if @mission.next_mission.nil? && @stage.next_stage.nil? redirect_to root_path, notice: "Congratulations, you have finished the last mission!" elsif @stage.next_stage.nil? redirect_to [@mission.next_mission, @mission.first_stage], notice: "Correct!

  • What's the difference between UI development and front-end development?

    - by Nick Lowman
    I'm a front-end developer and really enjoy jQuery and JavaScript. I've built a lot a websites, done some good jQuery work and built a few JavaScript based applications and would really like to get in UI development. Or so I thought. I guessed it would be pretty similar to what I already do except maybe a little more JavaScript heavy but when I looked into it all the job specs said I needed to know about Scrum or Agile development, knowledge of testing frameworks and a good knowledge of JavaScript frameworks and custom events. So, from the specs I get the idea that a UI developer is actually a dedicated JavaScript developer. Is that the case? I understand (with much help from the users on stackoverflow), about JavaScript OO, inheritance, closures, custom events, debugging in Firefox or Aptana etc, and the people I work with seem to think I pretty OK at what I do but clearly my knowledge is not good enough to go for UI jobs. If anyone could tell me a little more about UI development and if there are any good resources for learning about it I would be most grateful as I couldn't find much on the internet.

  • Gnome-terminal doesn't close at end of SSH session

    - by Simón
    I have defined in gnome-terminal that it closes at end of shell. When I press Control-D or I execute exit, the terminal closes. But if I open the SSH session with gnome-terminal -x ssh server and I execute reboot in the SSH session (to reboot the remote server), it hangs and it doesn't close. What's happening? This worked to me before but I have to reinstall my Ubuntu (in local) and now gnome-terminal doesn't close itself when SSH session ends.
