  • Game Boy Generates Music In An Unexpected Way [Video]

    - by Jason Fitzpatrick
    When we saw a link about a Game Boy generated melody we assumed it was a chip-tune track generated by the Game Boy’s sound processor. We were pleasantly surprised to see the Game Boy itself was the instrument. [via Geeks Are Sexy] Reader Request: How To Repair Blurry Photos HTG Explains: What Can You Find in an Email Header?

  • Reconciling the Boy Scout Rule and Opportunistic Refactoring with code reviews

    - by t0x1n
    I am a great believer in the Boy Scout Rule: Always check a module in cleaner than when you checked it out." No matter who the original author was, what if we always made some effort, no matter how small, to improve the module. What would be the result? I think if we all followed that simple rule, we'd see the end of the relentless deterioration of our software systems. Instead, our systems would gradually get better and better as they evolved. We'd also see teams caring for the system as a whole, rather than just individuals caring for their own small little part. I am also a great believer in the related idea of Opportunistic Refactoring: Although there are places for some scheduled refactoring efforts, I prefer to encourage refactoring as an opportunistic activity, done whenever and wherever code needs to cleaned up - by whoever. What this means is that at any time someone sees some code that isn't as clear as it should be, they should take the opportunity to fix it right there and then - or at least within a few minutes Particularly note the following excerpt from the refactoring article: I'm wary of any development practices that cause friction for opportunistic refactoring ... My sense is that most teams don't do enough refactoring, so it's important to pay attention to anything that is discouraging people from doing it. To help flush this out be aware of any time you feel discouraged from doing a small refactoring, one that you're sure will only take a minute or two. Any such barrier is a smell that should prompt a conversation. So make a note of the discouragement and bring it up with the team. At the very least it should be discussed during your next retrospective. Where I work, there is one development practice that causes heavy friction - Code Review (CR). Whenever I change anything that's not in the scope of my "assignment" I'm being rebuked by my reviewers that I'm making the change harder to review. This is especially true when refactoring is involved, since it makes "line by line" diff comparison difficult. This approach is the standard here, which means opportunistic refactoring is seldom done, and only "planned" refactoring (which is usually too little, too late) takes place, if at all. I claim that the benefits are worth it, and that 3 reviewers will work a little harder (to actually understand the code before and after, rather than look at the narrow scope of which lines changed - the review itself would be better due to that alone) so that the next 100 developers reading and maintaining the code will benefit. When I present this argument my reviewers, they say they have no problem with my refactoring, as long as it's not in the same CR. However I claim this is a myth: (1) Most of the times you only realize what and how you want to refactor when you're in the midst of your assignment. As Martin Fowler puts it: As you add the functionality, you realize that some code you're adding contains some duplication with some existing code, so you need to refactor the existing code to clean things up... You may get something working, but realize that it would be better if the interaction with existing classes was changed. Take that opportunity to do that before you consider yourself done. (2) Nobody is going to look favorably at you releasing "refactoring" CRs you were not supposed to do. A CR has a certain overhead and your manager doesn't want you to "waste your time" on refactoring. When it's bundled with the change you're supposed to do, this issue is minimized. The issue is exacerbated by Resharper, as each new file I add to the change (and I can't know in advance exactly which files would end up changed) is usually littered with errors and suggestions - most of which are spot on and totally deserve fixing. The end result is that I see horrible code, and I just leave it there. Ironically, I feel that fixing such code not only will not improve my standings, but actually lower them and paint me as the "unfocused" guy who wastes time fixing things nobody cares about instead of doing his job. I feel bad about it because I truly despise bad code and can't stand watching it, let alone call it from my methods! Any thoughts on how I can remedy this situation ?

  • Indian school boy never misses a class for 14 years. Applies for Gunnies Records

    - by Gopinath
    If you ask the question “What is the most fun activity?” to school or college kids, most of the kids would say “bunking classes”. Many of us are grown up bunking classes in the name of stomachache, relatives marriage, high fever, rain or some other reason. Here is a wonder kid who is an exception of regular school kids. Mohammed Omar, a 17 year Indian school boy, never skipped his classes for the past 14 years. His attendance records shows 100% for all the 14 years of school he attended so far and it’s an unbelievable track record. Omar lives in Kanpur, a suburban in Uttar Pradesh with parents and a younger brother. He attended school even when the area where he lives was once flooded, had high temperature. When flooded and motor vehicles were not able to run on the streets he loaned a bicycle from neighbors. When he was on high temperature he just popped a tablet and headed towards the school.  Whatever may be the adverse situation, he just found a way to attend school instead of bunking. He recently applied for Guinness Book of World Records. The determination of the boy is incredible and inspiration to many young. I  wish to see this guy soon flashing on TV Channels with Guinness World Records certificates on his hands. Source: NDTV, creative common image: flickr/seeveeaar

  • Shortening jQuery Code by Replacing Variable

    - by Jerry
    I have a form with a bunch of dropdown options that I'm dressing up by allowing the option to be selected by clicking links and (in the future, images) instead of using the actual dropdown. There are a lot of dropdowns and most all will repeat the same basic idea, and some will literally repeat just with different variables. Here's the HTML for one of those. <tr class="box1"> <td> <select id="cimy_uef_7"> <option value="Boy">Boy</option> <option value="Girl">Girl</option> </select> </td> </tr> Then the corresponding fancier links to click that will select the corresponding option in the dropdown. <div id="genderBox1"> <div class="gender"><a class="boy" href="">Boy</a></div> <div class="gender"><a class="girl" href="">Girl</a></div> </div> So, when you click the link "Boy" it will select the corresponding dropdown value "Boy" There are going to be multiple Box#, so I can just repeat the jQuery each time with the new variables, but there's surely a shorter way. Here's the jQuery that makes it work. //Box1 Gender var Gender1 = $('select#cimy_uef_7'); var Boy1 = $("#genderBox1 .gender a.boy"); var Girl1 = $("#genderBox1 .gender a.girl"); //On Page Load - Check Gender Box 1 Selection and addClass to corresponding div a if ( $(Gender1).val() == "Boy" ) { $(Boy1).addClass("selected"); } else { $(Boy1).removeClass("selected"); } if ( $(Gender1).val() == "Girl" ) { $(Girl1).addClass("selected"); } else { $(Girl1).removeClass("selected"); } //On Click - Change Gender Box 1 select based on image click $(Boy1).click(function(event) { event.preventDefault(); $(this).addClass("selected"); $(Gender1).val("Boy"); $(Girl1).removeClass("selected"); }); $(Girl1).click(function(event) { event.preventDefault(); $(this).addClass("selected"); $(Gender1).val("Girl"); $(Boy1).removeClass("selected"); }); My thought for shortening it was to just have a list of variables for each box and cycle through the numbers- 1,2,3,4 and have the jQuery grab the same # for each variable, but I can't figure out a way to do it. Let me know if there's anything else I can provide to make the question better. This is my best idea for shortening this code, as I'm still very much a beginner at jQuery, but I'm positive there are much better ideas out there, so feel free to recommend a better path if you see it :)

  • New user profile creation error - Windows cannot open *.exe

    - by Jake
    I have a windows 7 laptop with the user "mydomain\boy" that cannot log in to the laptop. the error message is something like "User profile service cannot log in the user boy". I then logged in with the domain admin account "mydomain\admin" and then went to delete the "mydomain\boy" from my computer system properties advance system settings user profiles settings. I also ensure that the user is deleted from control panel user accounts. I then also deleted the user folder c:\users\boy I also checked that the registry at this location HKLM\software\microsoft\windows nt\currentversion\profilelist\ and ensure that there is no entry for boy. I followed http://support.microsoft.com/kb/947215 using the method 3 "fix it for me" but does not seem to do anything. (or i don't know how to use it). AFTER EVERYTHING DONE ABOVE... Everytime i log in with a new user, be it boy, girl or anything other domain account (other than the admin account already created when I first logged in to begin the fix/break), it takes a long time, and when the "preparing desktop" goes away, it starts to exe cannot open error e.g. regsvr.exe etc.. file association problem with exe QUESTION (phew finally..): Please tell me how to fix it? Thanks!

  • Sound vs. Valid Argument

    - by MarkPearl
    Today I spent some time reviewing my Formal Logic course for my up coming exam. I came across a section that I have never really explored in any proper depth… the difference between a valid argument and a sound argument. Here go some notes I made… What is an argument? In this case we are not referring to a verbal fight, but more what we call a set of premise followed by a conclusion. Before we go further we need to understand what a premise is… a premise is a statement that an argument claims will induce or justify a conclusion. Think of a premise as an assumption that something is true. So, an argument can consist of one or more premises and a conclusion… When is an argument valid? An argument can be either valid or invalid. An argument is valid if, and only if, it is impossible for there to be a situation in which all it's premises are TRUE and it's conclusion is FALSE. It is generally easier to determine if an argument is invalid. Do this by applying the following… Assume that all the premises are true, then ask yourself if it is now possible for the conclusion to be false. If the answer is "yes," the argument is invalid. If it's "no," the argument is valid. Example 1… P1 – Mark is Tall P2 – Mark is a boy C –  Mark is a tall boy Walkthrough 1… Assume Mark is Tall is true and also assume that Mark is a boy. Based on these two premises, the conclusion is also true – Mark is a tall boy, thus the it is a valid argument. Let’s make this an invalid argument…   Example 2… P1 – Mark is Tall P2 – Mark is a boy C – Mark is a short boy Walkthrough 2… This would be an invalid argument, since from the premises we assume that Mark is tall and he is a boy, and then the conclusion goes against this by saying that Mark is short. Thus an invalid argument.   When is an argument sound? An argument is said to be sound when it is valid and all the premises are indeed true (not just assumed to be true). Rephrased, an argument is said to be sound when the conclusion will follow from the premises and the premises are indeed true in real life. In example 1 we were referring to a specific person, if we generalized it a bit we could come up with the following example.   Example 3 P1 – All people called Mark are tall P2 – I know a specific person called Mark C – He is a tall person   In this instance, it is a valid argument (we assume the premises are true, which leads to the conclusion being true), but the argument is NOT sound. In the real world there must be at least one person called Mark who is not tall. Something also to note, all invalid arguments are also unsound – this makes sense, if an argument is not valid, how on earth can it be true in the real world.   What happens when the premises contradict themselves? This is an interesting one… An argument is valid if, and only if, it is impossible for there to be a situation in which all it's premises are TRUE and it's conclusion is FALSE. When premises are contradictory, the argument is always valid because it is impossible for all the premises to be true at one time. Lets look at an example.. P1 - Elvis is dead P2 – Elvis is alive C – Laura is a woolly mammoth This is a valid argument, but not a sound one. Think about it. Is it possible to have a situation in which the premises are true and the conclusion is false? Sure, it's possible to have a situation in which the conclusion is false, but for the argument to be invalid, it has to be possible for the premises to all be true at the same time the conclusion is false. So if the premises can't all be true, the argument is valid. (If you still think the argument is invalid, draw a picture in which the premises are all true and the conclusion is false. Remember, there's only one Elvis, and you can't be both dead and alive.) For more info on this I suggest reading the following blog post.

  • How to create a rails habtm that deletes/destroys without error?

    - by Bradley
    I created a simple example as a sanity check and still can not seem to destroy an item on either side of a has_and_belongs_to_many relationship in rails. Whenever I try to delete an object from either table, I get the dreaded NameError / "uninitialized constant" error message. To demonstrate, I created a sample rails app with a Boy class and Dog class. I used the basic scaffold for each and created a linking table called boys_dogs. I then added a simple before_save routine to create a new 'dog' any time a boy was created and establish a relationship, just to get things setup easily. dog.rb class Dog < ActiveRecord::Base has_and_belongs_to_many :Boys end boy.rb class Boy < ActiveRecord::Base has_and_belongs_to_many :Dogs def before_save self.Dogs.build( :name => "Rover" ) end end schema.rb ActiveRecord::Schema.define(:version => 20100118034401) do create_table "boys", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "boys_dogs", :id => false, :force => true do |t| t.integer "boy_id" t.integer "dog_id" t.datetime "created_at" t.datetime "updated_at" end create_table "dogs", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end end I've seen lots of posts here and elsewhere about similar problems, but the solutions are normally using belongs_to and the plural/singular class names being confused. I don't think that is the case here, but I tried switching the habtm statement to use the singular name just to see if it helped (with no luck). I seem to be missing something simple here. The actual error message is: NameError in BoysController#destroy uninitialized constant Boy::Dogs The trace looks like: /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:105:in const_missing' (eval):3:indestroy_without_callbacks' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.4/lib/active_record/callbacks.rb:337:in destroy_without_transactions' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.4/lib/active_record/transactions.rb:229:insend' ...

  • deriving from NSTabViewItem

    - by Jonny
    I'm writing a Cocoa app. One dialog has 3 tabs, some of the tabs needs more loading time, so I want to load them lazily. Since each Tab is a NSTabViewItem class, so I'm trying to derive from it and overriding its view property. In the view getter method, I use a ViewController to load a view and returns out. In Debugging, I found NSTabViewItem -view method is get called correctly, but after that NSTabView tries to set Initial FirstResponder and crashed with message: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'In -[NSTabViewItem setInitialFirstResponder:], the first responder must descend from the tab view item's view. (Item: Invalid responder: )' I tried to override the -initialFirstResponder method to return a sub-view of my loaded view, but it still crashes the same place. does anyone know how to get it work correctly? Also is it correct way to do this by deriving the NSTabViewItem? thanks! -Jonny

  • C++ match string in file and get line number

    - by Corey
    I have a file with the top 1000 baby names. I want to ask the user for a name...search the file...and tell the user what rank that name is for boy names and what rank for girl names. If it isn't in boy names or girl names, it tells the user it's not among the popular names for that gender. The file is laid out like this: Rank Boy-Names Girl-Names 1 Jacob Emily 2 Michael Emma . . . Desired output for input Michael would be: Michael is 2nd most popular among boy names. If Michael is not in girl names it should say: Michael is not among the most popular girl names Though if it was, it would say: Micheal is (rank) among girl names The code I have so far is below.. I can't seem to figure it out. Thanks for any help. #include <iostream> #include <fstream> #include <string> #include <cctype> using namespace std; void find_name(string name); int main(int argc, char **argv) { string name; cout << "Please enter a baby name to search for:\n"; cin >> name; /*while(!(cin>>name)) { cout << "Please enter a baby name to search for:\n"; cin >> name; }*/ find_name(name); cin.get(); cin.get(); return 0; } void find_name(string name) { ifstream input; int line = 0; string line1 = " "; int rank; string boy_name = ""; string girl_name = ""; input.open("/<path>/babynames2004.rtf"); if (!input) { cout << "Unable to open file\n"; exit(1); } while(input.good()) { while(getline(input,line1)) { input >> rank >> boy_name >> girl_name; if (boy_name == name) { cout << name << " is ranked " << rank << " among boy names\n"; } else { cout << name << " is not among the popular boy names\n"; } if (girl_name == name) { cout << name << " is ranked " << rank << " among girl names\n"; } else { cout << name << " is not among the popular girl names\n"; } } } input.close(); }

  • Working for free?

    - by Jonny
    I came across this article Work for Free that got me thinking. The goal of every employer is to gain more value from workers than the firm pays out in wages; otherwise, there is no growth, no advance, and no advantage for the employer. Conversely, the goal of every employee should be to contribute more to the firm than he or she receives in wages, and thereby provide a solid rationale for receiving raises and advancement in the firm. I don't need to tell you that the refusenik didn't last long in this job. In contrast, here is a story from last week. My phone rang. It was the employment division of a major university. The man on the phone was inquiring about the performance of a person who did some site work on Mises.org last year. I was able to tell him about a remarkable young man who swung into action during a crisis, and how he worked three 19-hour days, three days in a row, how he learned new software with diligence, how he kept his cool, how he navigated his way with grace and expertise amidst some 80 different third-party plug-ins and databases, how he saw his way around the inevitable problems, how he assumed responsibility for the results, and much more. What I didn't tell the interviewer was that this person did all this without asking for any payment. Did that fact influence my report on his performance? I'm not entirely sure, but the interviewer probably sensed in my voice my sense of awe toward what this person had done for the Mises Institute. The interviewer told me that he had written down 15 different questions to ask me but that I had answered them all already in the course of my monologue, and that he was thrilled to hear all these specifics. The person was offered the job. He had done a very wise thing; he had earned a devotee for life. The harder the economic times, the more employers need to know what they are getting when they hire someone. The job applications pour in by the buckets, all padded with degrees and made to look as impressive as possible. It's all just paper. What matters today is what a person can do for a firm. The resume becomes pro forma but not decisive under these conditions. But for a former boss or manager to rave about you to a potential employer? That's worth everything. What do you think? Has anyone here worked for free? If so, has it benefited you in any way? Why should(nt) you work for free (presuming you have the money from other means to keep you going)? Can you share your experience? Me, I am taking a year out of college and haven't gotten a degree yet so that's probably why most of my job applications are getting ignored. So im thinking about working for free for the experience?

    Is Extreme Programming Dying? I've been reviewing my fellow students reports on extreme programming.(I am a student myself) Some students are claiming that extreme programming lacks in empirical evidences, and is relevantly new, hence lacking in empirical evidence. XP is already 13 years old it should be considered as new, from my perspective. I guess the practices of XP has been tweaked and used in newer methodologies such as scrum. What are your point of view on this, do you guys think XP is Dying?

  • Canonicals with differing content

    - by Jimbo Jonny
    Interesting conundrum here with canonicals. Lets say I have a site with a "verified" system where other websites can become so and so "verified". Their url to send people to to confirm verification is something like "blah.com/verify/company1" and "blah.com/verify/company2". But logically "blah.com/verify" itself is not verifying anyone in particular, so it redirects to the signup form to get verified, at "blah.com/verify/register" As far as the actual companies registered, I figure it doesn't make sense to index every individual url with only the tiny difference of which company name it's saying yay or nay to being verified, so canonicals could come in handy on those pages to condense the indexing. Yet making "blah.com/verify" the canonical "hub" doesn't work well because it's a signup form, not a verification page, so technically has quite different content from the various verification pages themselves. But at the same time it's a bit unfair to choose 1 company to point all the canonical benefits too to use that as the "hub", yet a bit wasteful to have google index every individual verification page and spread out all that linkjuice. Basically, I'm just looking for advice, what's best for this from a search engine standpoint?

  • Is 'Protection' an acceptable Java class name

    - by jonny
    This comes from a closed thread at stack overflow, where there are already some useful answers, though a commenter suggested I post here. I hope this is ok! I'm trying my best to write good readable, code, but often have doubts in my work! I'm creating some code to check the status of some protected software, and have created a class which has methods to check whether the software in use is licensed (there is a separate Licensing class). I've named the class 'Protection', which is currently accessed, via the creation of an appProtect object. The methods in the class allow to check a number of things about the application, in order to confirm that it is in fact licensed for use. Is 'Protection' an acceptable name for such a class? I read somewhere that if you have to think to long in names of methods, classes, objects etc, then perhaps you may not be coding in an Object Oriented way. I've spent a lot of time thinking about this before making this post, which has lead me to doubt the suitability of the name! In creating (and proof reading) this post, I'm starting to seriously doubt my work so far. I'm also thinking I should probably rename the object to applicationProtection rather than appProtect (though am open to any comments on this too?). I'm posting non the less, in the hope that I'll learn something from others views/opinions, even if they're simply confirming I've "done it wrong"!

  • What makes a project big?

    - by Jonny
    Just out of curiosity what's the difference between a small, medium and large size project? Is it measured by lines of code or complexity or what? Im building a bartering system and so far have about 1000 lines of code for login/registration. Even though there's lots of LOC i wouldnt consider it a big project because its not that complex though this is my first project so im not sure. How is it measured?

  • What's a good open source cloud computing software? [closed]

    - by boy
    In particular, the "cloud" computing that I'm referring to is: I'm going to get some Linux servers. Then I have pretty big computing tasks to do every day. So my goal is to be able to run some shell command to request an "instance" (ie, if a server has 4 CPU, then the computing software will configure that server to have 4 instances, assuming all my tasks are single thread). Ideally, then I can run the following command: ./addjobs somebatchfile where somebatch file contains one command per line ./removejobs all ./listalljobs (ie, everything is done in shell. And the "computing software" can return me the hostname that's available in some environment variable, etc) And that's all I needed. I run into OpenStack.. but it seems too complicated for this purpose (ie, it does all the Imagine sharing stuff, etc).. All I want, is something SIMPLE that manages the Linux boxes for me and I'm just going to run shell commands on them... Is there such open source software? Thanks,
