  • How can I make a boring project (another WordPress site) interesting?

    - by Christopher Altman
    WordPress is my example, but the question can be generalized to any technology that is not particularly interesting. To me, WordPress takes away the intellectually gratifying pieces of coding. I would rather write a new version of WordPress than write a WordPress theme and glue together some plugins. I am using WP because my company dictates the platform for some of our clients (I do not disagree with the choice from a business perspective, WP is quick and cheap to implement). My question is, how can I make my next WordPress project interesting? I want to advance my understanding of the fundamentals of programming (aka data structures, algorithms, and caching) but do not see how I can achieve this when coding another WP site. I have a fairly tight understanding of front-end technologies and believe I have made WP do things it was never intended to do. Examples are here and here. Solving front-end related problems is not as interesting as coding a full stack application. Any advice will help.

  • At which point is a continuous integration server interesting?

    - by Cedric Martin
    I've been reading a bit about CI servers like Jenkins and I'm wondering: at which point is it useful? Because surely for a tiny project where you'd have only 5 classes and 10 unit tests, there's no real need. Here we've got about 1500 unit tests and they pass (on old Core 2 Duo workstations) in about 90 seconds (because they're really testing "units" and hence are very fast). The rule we have is that we cannot commit code when a test fail. So each developers launches all his tests to prevent regression. Obviously, because all the developers always launch all the test we catch errors due to conflicting changes as soon as one developer pulls the change of another (when any). It's still not very clear to me: should I set up a CI server like Jenkins? What would it bring? Is it just useful for the speed gain? (not an issue in our case) Is it useful because old builds can be recreated? (but we can do this to with Mercurial, by checking out old revs) Basically I understand it can be useful but I fail to see exactly why. Any explanation taking into account the points I raised above would be most welcome.

  • When dealing with a static game board, what are some methods to make it more interesting?

    - by Ólafur Waage
    Let's say you have a game board that you look at. It does not move but there is some action going on. For example Chess, Checkers, Solitaire. The game I'm working on is not one of this but it's a good reference. What are some methods you can apply to the game or the design that increases the appeal of the user to the game. Of course you can make it prettier but what are some other methods you can use? For example: Visual cues, game design changes, user interface arrangement, etc.

  • Interesting fault attempting to install Ubuntu 12.0.4.3 OR 13.10 on MSI GS70 2OD-001US

    - by cjaredrun
    Attempting to install Ubuntu on an MSI GS70 2OD-001US notebook pre-installed with Windows 8. For the record this is what I have attempted: All cases were attempted with Ubuntu 12.0.4.3 AND 13.10 images via USB drives Case 1 - Attempt no changes and simply boot from USB Result: It seems to want to work initially. The Ubuntu logo pops up and the dots start moving. After a few seconds the dots freeze and this screen is shown: http://i.imgur.com/C7pyMRk.jpg Case 2 - Start playing with BIOS - In Windows turning off fast boot - In BIOS turning off Secure boot - In BIOS turning off UEFI and selecting LEGACY Result: Brought to a black screen with a - blinking at me. Case 3 - Alternating BIOS settings - In Windows turning off fast boot - In BIOS turning off Secure boot - in BIOS turning off UEFI and selecting UEFI with CSM Result: Brought to a black screen no other indication of change. It's pretty frustrating to feel locked out of a laptop that I have paid good money for, I'm sure I am not alone in that case. It does however appear that there has been some success, so I am hopeful that someone might be able to help me. FYI: Dual booting is not necessary for me, if that helps at all... I'm not sure if this is a reasonable option, but if I completely wipe clean the hdds, no particle of Windows at all, would this still be a problem? Also would opening up the laptop and replacing the HDDS with brand new ones be a solution as well? Thanks for any input or suggestions.

  • Interesting opensource projects to contribute to as a sysadmin?

    - by wu
    I know that as a sysadmin you can contribute to opensource projects such as a Debian and Fedora. Joining their infrastructure groups and help with administration. I'm just wondering if there are any other interesting opensource projects/communities. To which sysadmin with a free time can contribute and sharpen his skills.

  • What is more interesting or powerful: Curry/Mercury/Lambda-Prolog/your suggestion.

    - by Bubba88
    Hi! I would like to ask you about what formal system could be more interesting to implement from scratch/reverse engineer. I've looked through some existing and rather open (open in the sense of free/open-source) projects of logical/declarative programming systems. I've decided to make up something similar in my free time, or at least to catch the general idea of implementation. It would be great if some of these systems would provide most of the expressive power and conciseness of modern academic investigations in logic and it's relation with computational models. What would you recommend to study at least at the conceptual level? For example, Lambda-Prolog is interesting particularly because it allows for higher order relations, but AFAIK (I might really be mistaken :)) is based on intuitionist logic and therefore lack the excluded-middle principle; that's generally a disatvantage for me.. I would also welcome any suggestions about modern logical programming systems which are less popular but more expressive/powerful. I guess, this question will need refactoring, but thank you in advance! :)

  • interesting Delphi open-source applications/projects (not components/component packs!)

    - by vic
    Hi, I'd like to know what interesting open-source projects written in Delphi (or FreePascal) you know? I'm not asking for components/components packs, I know there were questions for that. Please do not duplicate answers, vote them up instead ;) Please do not point components/packs/closed-source projects. Please provide at least word of description ;) Two examples from me: PyScripter - Python IDE written in Delphi - hosted at google code (*) HeidiSQL - MySQL Frontend - http://www.heidisql.com/ (*)sorry, as a new user I can't post more than one link :(

  • What are the most interesting equivalences arising from the Curry-Howard Isomorphism?

    - by Tom
    I came upon the Curry-Howard Isomorphism relatively late in my programming life, and perhaps this contributes to my being utterly fascinated by it. It implies that for every programming concept there exists a precise analogue in formal logic, and vice versa. Here's an "obvious" list of such analogies, off the top of my head: program/definition | proof type/declaration | proposition inhabited type | theorem function | implication function argument | hypothesis/antecedent function result | conclusion/consequent function application | modus ponens recursion | induction identity function | tautology non-terminating function | absurdity tuple | conjunction (and) disjoint union | exclusive disjunction (xor) parametric polymorphism | universal quantification So, to my question: what are some of the more interesting/obscure implications of this isomorphism? I'm no logician so I'm sure I've only scratched the surface with this list. For example, here are some programming notions for which I'm unaware of pithy names in logic: currying | "((a & b) => c) iff (a => (b => c))" scope | "known theory + hypotheses" And here are some logical concepts which I haven't quite pinned down in programming terms: primitive type? | axiom set of valid programs? | theory ? | disjunction (or)

  • What are interesting ideas for experimenting with Artificial Neural Networks?

    - by Gerald Kaszuba
    I'm after a list of possible neural network implementations that one can do to learn how to use it. What other possibilities are there? Here's the list so far: Games tic-tac-toe Connect 4 Chess Go Visual recognition Character recognition (typefaces, letters, numbers, etc) Facial recognition Audio recognition Language detection Male vs female Word recognition Language detection (natural, programming)

  • What are some interesting fringe programming topics that might have hands-on training?

    - by hal10001
    Whenever training topic questions are asked, the answers are fairly typical, and involve a pretty limited subset of topics like OO, design patterns, algorithms, web services, SQL, etc., but I wonder if there are some fringe topics that are still applicable to the programming field and would give me a more rounded approach to development. When I think of "fringe", I think of 2600: The Hacker Quarterly articles that discuss how to use real world (sometimes obscure) exploits, or something like Maker Faire that demonstrates embedded systems programming using Arduino. I have around $1500-2000 to spend, and my job entails Java technologies, but that does not limit my options.

  • What are good or interesting Assembler-like languages, but at a higher level?

    - by CodexArcanum
    I've been looking at L.in.oleum and am intrigued by it's mix of higher-level constructs (loops, dynamic variables) with low-level assembler power (registers). Are there other languages like Lino out there, which blend the speed of assembler with productivity enhancing features? EDIT: I realized this kind of sounds like an ad. I'm genuinely interested in other assembler-like languages, Lino is just the only one I happen to know of.

  • How do I write an RSpec test to unit-test this interesting metaprogramming code?

    - by Kyle Kaitan
    Here's some simple code that, for each argument specified, will add specific get/set methods named after that argument. If you write attr_option :foo, :bar, then you will see #foo/foo= and #bar/bar= instance methods on Config: module Configurator class Config def initialize() @options = {} end def self.attr_option(*args) args.each do |a| if not self.method_defined?(a) define_method "#{a}" do @options[:"#{a}"] ||= {} end define_method "#{a}=" do |v| @options[:"#{a}"] = v end else throw Exception.new("already have attr_option for #{a}") end end end end end So far, so good. I want to write some RSpec tests to verify this code is actually doing what it's supposed to. But there's a problem! If I invoke attr_option :foo in one of the test methods, that method is now forever defined in Config. So a subsequent test will fail when it shouldn't, because foo is already defined: it "should support a specified option" do c = Configurator::Config c.attr_option :foo # ... end it "should support multiple options" do c = Configurator::Config c.attr_option :foo, :bar, :baz # Error! :foo already defined # by a previous test. # ... end Is there a way I can give each test an anonymous "clone" of the Config class which is independent of the others?

  • Interesting AS3 hash situation. Is it really using strict equality as the documentation says?

    - by Triynko
    AS3 Code: import flash.utils.Dictionary; var num1:Number = Number.NaN; var num2:Number = Math.sqrt(-1); var dic:Dictionary = new Dictionary( true ); trace(num1); //NaN trace(num2); //NaN dic[num1] = "A"; trace( num1 == num2 ); //false trace( num1 === num2 ); //false trace( dic[num1] ); //A trace( dic[num2] ); //A Concerning the key comparison method... "The Dictionary class lets you create a dynamic collection of properties, which uses strict equality (===) for key comparison. When an object is used as a key, the object's identity is used to look up the object, and not the value returned from calling toString() on it." If Dictionary uses strict equality, as the documentation states, then how is it that num1 === num2 is false, and yet dic[num1] resolves to the same hash slot as dic[num2]?

  • Is there any interesting jobs available for C++ other than device drivers / firmwares developments?

    - by AKN
    Hi, Initially C was used for designing drivers / firmwares and all that. Right now this has been taken over by C++. Ok. Let me not deviate this question. I would like to know where else C++ is being used and how you see its future? You can also list out pros and cons of C++ compared to other languages. Would like to see a healthy and meaningful discussion on C++ current usage and its future?! Cheers! AKN

  • Interesting Scala typing solution, doesn't work in 2.7.7?

    - by djc
    I'm trying to build some image algebra code that can work with images (basically a linear pixel buffer + dimensions) that have different types for the pixel. To get this to work, I've defined a parametrized Pixel trait with a few methods that should be able to get used with any Pixel subclass. (For now, I'm only interested in operations that work on the same Pixel type.) Here it is: trait Pixel[T <: Pixel[T]] { def mul(v: Double): T def max(v: T): T def div(v: Double): T def div(v: T): T } Now I define a single Pixel type that has storage based on three doubles (basically RGB 0.0-1.0), I've called it TripleDoublePixel: class TripleDoublePixel(v: Array[Double]) extends Pixel[TripleDoublePixel] { var data: Array[Double] = v def this() = this(Array(0.0, 0.0, 0.0)) def toString(): String = { "(" + data(0) + ", " + data(1) + ", " + data(2) + ")" } def increment(v: TripleDoublePixel) { data(0) += v.data(0) data(1) += v.data(1) data(2) += v.data(2) } def mul(v: Double): TripleDoublePixel = { new TripleDoublePixel(data.map(x => x * v)) } def div(v: Double): TripleDoublePixel = { new TripleDoublePixel(data.map(x => x / v)) } def div(v: TripleDoublePixel): TripleDoublePixel = { var tmp = new Array[Double](3) tmp(0) = data(0) / v.data(0) tmp(1) = data(1) / v.data(1) tmp(2) = data(2) / v.data(2) new TripleDoublePixel(tmp) } def max(v: TripleDoublePixel): TripleDoublePixel = { val lv = data(0) * data(0) + data(1) * data(1) + data(2) * data(2) val vv = v.data(0) * v.data(0) + v.data(1) * v.data(1) + v.data(2) * v.data(2) if (lv > vv) (this) else v } } Now I want to write code to use this, that doesn't have to know what type the pixels are. For example: def idiv[T](a: Image[T], b: Image[T]) { for (i <- 0 until a.data.size) { a.data(i) = a.data(i).div(b.data(i)) } } Unfortunately, this doesn't compile: (fragment of lindet-gen.scala):145: error: value div is not a member of T a.data(i) = a.data(i).div(b.data(i)) I was told in #scala that this worked for someone else, but that was on 2.8. I've tried to get 2.8-rc1 going, but it doesn't compile for me. Is there any way to get this to work in 2.7.7?
