• What are the basic skills a BEGINNING JavaScript programmer should have?

  - by Sanford

  In NYC, we are working on creating a collaborative community programming environment and trying to segment out software engineers into differing buckets. At present, we are trying to define: Beginners Intermediates Advanced Experts (and/or Masters) Similar to an apprenticeship, you would need to demonstrate specific skills to achieve different levels. Right now, we have identified Beginner programming skills as: Object - method, attributes, inheritance Variable - math, string, array, boolean - all are objects Basic arithmetic functions - precedence of functions String manipulation Looping - flow control Conditionals - boolean algebra This is a first attempt, and it is a challenge since we know the natural tension between programming and software engineering. How would you create such a skills-based ranking for JavaScript in this manner? For example, what would be the Beginner Javascript skills that you would need to have to advance to the Intermediate Training? And so on.

• Can we compare programming languages ergonomically?

  - by Nick Rosencrantz

  For instance, would Python be a more ergonomic programming language since it doesn't force you to make curly braces which requires the AltGr key. Also Python usually requires less code to achieve the same or am I being biased towards Python and PHP actually is an ergonomical and comfortable language despite forcing the programmer to use the AltGr key? Isn't forcing the programmer to use the AltGr key not very ergonomical?

• Need help on a problemset in a programming contest

  - by topher

  I've attended a local programming contest on my country. The name of the contest is "ACM-ICPC Indonesia National Contest 2013". The contest has ended on 2013-10-13 15:00:00 (GMT +7) and I am still curious about one of the problems. You can find the original version of the problem here. Brief Problem Explanation: There are a set of "jobs" (tasks) that should be performed on several "servers" (computers). Each job should be executed strictly from start time Si to end time Ei Each server can only perform one task at a time. (The complicated thing goes here) It takes some time for a server to switch from one job to another. If a server finishes job Jx, then to start job Jy it will need an intermission time Tx,y after job Jx completes. This is the time required by the server to clean up job Jx and load job Jy. In other word, job Jy can be run after job Jx if and only if Ex + Tx,y = Sy. The problem is to compute the minimum number of servers needed to do all jobs. Example: For example, let there be 3 jobs S(1) = 3 and E(1) = 6 S(2) = 10 and E(2) = 15 S(3) = 16 and E(3) = 20 T(1,2) = 2, T(1,3) = 5 T(2,1) = 0, T(2,3) = 3 T(3,1) = 0, T(3,2) = 0 In this example, we need 2 servers: Server 1: J(1), J(2) Server 2: J(3) Sample Input: Short explanation: The first 3 is the number of test cases, following by number of jobs (the second 3 means that there are 3 jobs for case 1), then followed by Ei and Si, then the T matrix (sized equal with number of jobs). 3 3 3 6 10 15 16 20 0 2 5 0 0 3 0 0 0 4 8 10 4 7 12 15 1 4 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 4 8 10 4 7 12 15 1 4 0 50 50 50 50 0 50 50 50 50 0 50 50 50 50 0 Sample Output: Case #1: 2 Case #2: 1 Case #3: 4 Personal Comments: The time required can be represented as a graph matrix, so I'm supposing this as a directed acyclic graph problem. Methods I tried so far is brute force and greedy, but got Wrong Answer. (Unfortunately I don't have my code anymore) Could probably solved by dynamic programming too, but I'm not sure. I really have no clear idea on how to solve this problem. So a simple hint or insight will be very helpful to me.

• JHeadstart search with default values

  - by christian.bischof

  JHeadstart has a powerful generator for ADF Faces pages. One of the features of the generator is the generation of search functionality into a page. The search functionality offers a "Quicksearch" with a single search item and an "Advanced Search" for multiple search criteria. Sometimes it would be nice to have initial values for the search criteria, but this is not supplied by JHeadstart by default.

• Aspect-oriented Programming and Code Contracts in ASP.NET MVC

  There are some aspects to application programming, such as logging, tracing, profiling, authentication and authorization that cut across the business objects. These are difficult to deal with in an object-oriented paradigm without resorting to code-injection, code-duplication or interdependencies. In ASP.NET MVC, you can use attributes in the form of action filters to provide a neater way of implementing these cross-curring concerns.

• Embeding a generic google search with autocomplete - not a custom site search

  - by picxelplay

  Most people's home page is google.com. My homepage is just a custom html page hosted on my computer. I do this because I am a web developer, and I have several projects that I work on a one time, so I like to have quick links to all of them. On that page I usually just have a Link to google.com for when I want to search. But below all of my quick links, I want to add a google search box (with Autocompletions). I first used a simple iframe to embed google.com into the page, but then my search results were confined to that iframe. I wanted to search for something, then my results would open in a new tab. I then came across this code snippet but it doesn't have Autocompletions: http://www.refactory.org/s/google_search/view/2 How can I add Autocompletions to this? Or is there a better way of doing it? Thanks in advance for any advice

• Am I getting Scheme wrong?

  - by nischayn22

  Inspired by the numerous posts about the importance of learning Lisp/Scheme I started to learn Scheme two days back, I am using the book "The little Schemer" and have completed half of it. But I still haven't learned anything new, the book teaches about recursion which I already understand and uses lambda (which I can think of a way to define a function in C). I still haven't got the concept of functional programming (please point to some example of functional compared to normal programming methods in C/C++ so I can get it). Am I learning in the wrong way? or is "The little Schemer" for a newbie in programming and I should look for some other books?

• High paid non-finance programming roles? [closed]

  - by Ian

  Besides finance (front-office/high frequency trading) developer roles, are there any other very well paid programming roles, specifically for C++ or Java? One particular industry I would find interesting is the energy industry? However, I completed an internship for one of the massive energy companies and their "IT department" was nothing more than Microsoft Access- they outsourced all the technical work to IBM and Accenture. EDIT: USD 110k+ Defense would sounds great except the fact I am not a US citizen :)

• schema.org specification for generic pages or posts on a CMS

  - by NateWr

  I'm trying to determine the best possible schema.org type to declare for the content section in the template of a content management system, which will handle regular news posts for small, local hospitality businesses. The type should represent the content of that page, which is likely to be a wide range of things. The description for Article pretty strongly encourages its use to be limited to the articles of a publication. For purely semantic reasons, I'm not sure if Blog is appropriate in this case -- businesses won't be creating typical "blog" content but are more likely to be writing about upcoming events, special deals, awards, etc. Would Webpage be appropriate in this instance? Although I'm a fan of the schema.org concept, I frequently find myself unsure how broadly or narrowly I'm meant to infer the meaning of a type. In such cases, is it safe to use a high-level element, such as CreativeWork, or does this blunt the usefulness of the markup?

• What are the advantages and Disadvantages of Using an Aspect Orientated Programming Paradigm

  - by JHarley1

  Ok so here is the question: What are the advantages and Disadvantages of Using an Aspect Orientated Programming Paradigm. My advantages and disadvantages thus far: Advantages: Complements object orientation. Modularizes cross-cutting concerns improving code maintainability and understandability. Disadvantage: Not the easiest of concepts to grasp - not as well documented as O-O O-O goes far enough in the separation of concerns... List item Would anyone like to challenge any of these/ add their own? Many Thanks, J

• Generic Content Player?

  - by Jantire

  The general idea on the web appears to be that video/audio are to be separated with plain text. By separated, I mean you have a place that plays video/audio and a place that you read text. This is because it is widely understood that they are vastly different. However, audio and video are just another way of communication, just like text. So why do we separate the two even if they are nearly the same thing? Correct me if I'm wrong but, most tutorials are either plain text how-to's (wiki-style) or visual/auditory instructional videos (YouTube). Why aren't the two combined? Or, if it's already been done can someone reply with the link? This might be bordering off-topic and if it is off-topic then please point me to the right place so it won't be. This might also appear to be an obvious question, however I'm not sure if this subject has really been deeply thought-out by more than a few individuals.

• General programming techniques to speed up coding time

  - by mcwise

  I am preparing for a programming contest in C++ where it is all about producing working code in a short time. An example would be to use a macro to get the minimum of two ints(but I was told that you shouldn't use macros as they are not type-safe) or using memsets to initialize arrays (but I was told that you shouldn't use memsets in C++). This leads to the question, what kind of coding techniques exist to use at a real job?

• Programming tourism

  - by Andrew_B

  I'm going on vacation to Paris, France for 10 days. Actually, it's my girlfriend's wish to go there but I'm not very interested in visiting, sightseeing, etc. Recently, I came up with an idea of trying to do something like programming tourism. :) I'd like to do something related to programming in a startup-like company. I do not want a salary or any kind of compensation. I want to overview process, social aspects, environment and "what it feels like" to development software in another country. I'm from Russia. I've been a software developer since 2003. I prefer C#4 but I'm ready to use anything Turing-complete. I have some MS certifications and am familiar with all .NETs since 1.1. Currently I'm finishing PhD in CS. I'm interested in multidimensional indexing and I can turn any piece of data and code to OLAP system. :) But it'd take too much time. What can I do? I have no more than one week. I want a totally complete project in a short amount of time. Implement some features in well-tested project Do a code review Debug memory, performance and concurrency issues Do unit testing So, about the questions: Is it legal? I'm ready to sign NDA if it's necessary. I'll have tourist visa. Is it possible? I'm really sure that bureaucratic companies with lots of HRs and PMs will not allow such experiments. But small companies can afford it. I'm ready to guarantee support on my code after leaving home :) P.S. I still havn't started learning French :) I hope it will not take too much time :) P.P.S. Yes, it's girlfriend-approved. What's in it for me? It's fun. It's fun to see new systems and people who created them. It's fun to complete meaningful things. Quickly. What's in it for them? Feature, debug, review or test. If my short-term colleagues will like this style of working I can invite them to make same trip into my company :) I think in Russia it's even more exciting :)

• Getting my younger brother started on programming

  - by SmartLemon

  My younger brother is 13 years old, I started programming when I started to develop Android applications when I was 15, last year my brother gained an interest in it and he would always pestering me about letting him make something himself, so I wrote him a few tutorials and he built himself a small application that had a few buttons that did something, I think you put in your dob and it would tell you what day you were born on, he took a couple of days building up to his final application, maybe even a week, learning everything he needed. Since then he hasn't really done much more because I have been engulfed in work and such where I have my own programming problems to sort out. I told him that when he was my age (I am 17) that he should be better then me, he was a bit sceptical about this however. I dont think he has as much logical reasoning as I would think he needs to solve more complex problems, but shouldnt that just develop over time as it did with me? He has been pestering me for the past week or something to write him more tutorials, but I didn't have time. All I had with me was a playlist I had downloaded from the new boston from youtube for C++, it's about 73 videos. He is currently about 20-30 videos in, he has come to ask me a few questions about it and thats it. Should I have really properly started him with C++? Should I stop him now and start him again on python or ruby? I know that C++ shouldn't really be a beginners language, especially for someone who is only 13, by the time this question is answered will probably be up to learning about inheritance or something. Some people may see this as not a real question, but it is, and should be used as a reference for others. I want to know, should I start him on a different language whch is more easy? What language then? And would it be better for me to teach him myself (I would make time) or just continue him with the new boston? There are a few more questions throughout this question but these are the main ones. Part of the question people seem to be neglecting is me asking whether I should change what language he is learning to another, or since he is already pretty far through the tutorials should I just leave him with C++ and he can learn the other languages freely by himself?

• Overused or abused programming techniques

  - by Anto

  Are there any techniques in programming that you find to be overused (IE used way more excessively than what they should be) or abused, or used a bit for everything, while not being a really good solution to many of the problems which people attempt to solve with it. It could be regular expressions, some kind of design pattern or maybe an algorithm, or something completely different. Maybe you think people abuse multiple inheritance etc.

• Someone who needs inspiration [on hold]

  - by Anestis

  My apologies if it is not a code problem. However, it is a problem that concerns programming. As a recently graduated Computer Systems Engineering I have gained some basic knowledge with programming using JAVA. I have realised 2 things, the first one is that I realy liked programming and the second is that I am not good at all. More specifically, I struggle on problem solving and when i face complex tasks I feel lost. Every day , I spend some quality time doing simple exercises in order to be more familiar with JAVA. My target is to become a good programmer and find a job on a software company. I am afraid maybe " I dont have it" thats why I am asking you , what should I do? Should i give up? Thanks in advance, Anestis
