  • The Evolution of 8-Bit [Video]

    - by Jason Fitzpatrick
    In this nostalgia filled short video, PBS takes a retrospective look at the history and the evolution of early 8-bit video games. Beginning with early Atari and Nintendo video games, the 8-bit aesthetic has been a part of our culture for over 30 years. As it moved through the generations, 8-bit earned its independence from its video game roots. The idea of 8-bit now stands for a refreshing level of simplicity and minimalism, is capable of sonic and visual beauty, and points to the layer of technology that suffuses our modern lives. No longer just nostalgia art, contemporary 8-bit artists and chiptunes musicians have elevated the form to new levels of creativity and cultural reflection.

  • Interesting conversation about the nature of info-wars

    - by Malcolm Anderson
    Over at Schlock Mercenary, Howard Taylor has started a facinating conversation on the nature of Info-Wars. As Howard puts it:   Somebody (I forget who) tweeted that the Wikileaks fight right now is the first infowar in history. I disagree. I think we've fought numerous infowars in the last fifteen years. And that's really what I want to see discussed in the comments. We can argue right and wrong until the eCows come 127.0.0.1 but nobody is going to walk away convinced. I want to see a list of information-age conflicts that you feel qualify as "infowar." Me, I think the RIAA vs file-sharing qualifies. My buddy Rodney suggested RBLs vs Spammers (the spammers won that one.) Somebody pointed out that the Secret Service raid on Steve Jackson Games back in the 80's might qualify.

  • When should we use weak entities when modelling a database?

    - by Songo
    This is basically a question about what are weak entities? When should we use them? How should they be modeled? What is the main difference between normal entities and weak entities? Does weak entities correspond to value objects when doing Domain Driven Design? To help keep the question on topic here is an example taken from Wikipedia that people can use to answer these question: In this example OrderItem was modeled as a weak entity, but I can't understand why it can't be modeled as a normal entity. Another question is what if I want to track the order history (i.e. the changes in it status) would that be a normal or weak entity?

  • When Programming will become deprecated [closed]

    - by Vibeeshan
    Possible Duplicate: Will programmers be around in a few years? According to the history of programming, with each new generation of software engineering it seems to become easier and easier. Machine Code - Assembly - Programming Languages - easier - more easier - etc. If this situation continues anyone will be able to program (even complex systems). Even now, most of the kids study programming at school (Pascal , VB, etc.). Will be there any jobs called software engineering in future (if everyone know to program). ....and.... What do you think about the future of software development?

  • Is the Google Webmaster Tools verification temporary?

    - by Senseful
    When you add a site to Google Webmaster Tools, it asks you to verify it (e.g. via a <meta> tag). I verified a site a while ago, but when I logged in, I noticed that it isn't verified anymore. The history shows that it was verified 58 days ago, but then 30 days ago it tried and failed saying that "revierification failed". I'm not sure if this is a result of some setting I changed which required a reverification, or if Google Webmaster Tools periodically tries to verify the site. I was under the impression that the verification only happens once when you add the site, and then you can delete the <meta> tag. If this is not how it works, and it does reverify periodically, will it require a different <meta> tag value or can I keep the original one I used and never have to worry about it again?

  • Which software development methodologies can be seen as foundations

    - by Bas
    I'm writing a small research paper which involves software development methodologiess. I was looking into all the available methodology's and I was wondering, from all methodologies, are there any that have provided the foundations for the others? For an example, looking at the following methodologies: Agile, Prototyping, Cleanroom, Iterative, RAD, RUP, Spiral, Waterfall, XP, Lean, Scrum, V-Model, TDD. Can we say that: Prototyping, Iterative, Spiral and Waterfall are the "foundation" for the others? Or is there no such thing as "foundations" and does each methodology has it's own unique history? I would ofcourse like to describe all the methodology's in my research paper, but I simply don't have the time to do so and that is why I would like to know which methodologies can be seen as representatives.

  • How to manage primary key while updating [migrated]

    - by Subin Jacob
    In the following table primaryKeyColumn is primary key. To maintain the data history I always uses the values with WHERE condition(WHERE StatusColumn=1) And will set the StatusColumn to 0 if the data is edited (So that I could keep the previous data). But the problem is, if I update it to 0 , I can't insert the same key to primarykeycolumn since the column validated for primary keys. How can I manage these kind of validations? what the mistake I did in this design? primaryKeyColumn ValueColumn StatusColumn ---------------- ----------- ------------ 2 Name1 1 3 Name2 1 4 Name3 0

  • Use the latest technology or use a mature technology as a developer?

    - by Ted Wong
    I would like to develop an application for a group of people to use. I have decided to develop using python, but I am thinking of using python 2.X or python 3.X. If I use python 2.X, I need to upgrade it for the future... But it is more mature, and has many tools and libraries. If I develop using 3.X, I don't need to think of future integration, but currenttly it doesn't have many libraries, even a python to executable is not ready for all platforms. Also, one of the considerations is that it is a brand new application, so I don't have the history burden to maintain the old libraries. Any recommendation on this dilemma? More information about this application: Native application Time for maintenance: 5 years+ Library/Tools must need: don't have idea, yet. Must need feature that in 2.X: Convert to an executable for both Windows and Mac OS X

  • Using branchs for a mini project or module of project: Good practice?

    - by TheLQ
    In my repo I have 3 closely related mini projects: 1 server and 2 clients. They are all quite small (<3 files each). Since they are so small and so closely related I just dropped them in folders in one single repo. However now that I know I can't clone a single directory in my VCS of choice (Mercurial), I'm considering splitting them up. However I'm confused about general best practice: Is it okay to put different small projects in different branches, or should they all go in different repos? I'm currently leaning towards branching since I can't easily splice out the file history of the different projects but then your using a feature in a way it wasn't meant to be used.

  • How should I make searching a relational database more efficient?

    - by Travis J
    This is in the scope of a web application. I have a database which has a few nested relations. There is a feature which depicts the history of a large chain of relations. It is essentially a data analysis feature. The issue is that in order to search, a large object graph must be loaded - the loading time for this object graph is not quick enough to be viable. The problem is that without loading the whole graph it makes searching from a single string nearly impossible. In order to search, explicit fields must be specified and the search data supplied. Is there a design pattern for exposing the data in a way which facilitates a single string search instead of having to explicitly define parameters?

  • Using a DisplayLink USB video adapter on Ubuntu 12.10

    - by Jason R
    The line of USB video adapters made by DisplayLink has a somewhat sordid history under Linux. In past Ubuntu releases, the process of getting them to work has been somewhat difficult, inspiring a number of past questions on this site: example 1 example 2 example 3 However, there are some indications that version 3.5 of the Linux kernel (which is used by 12.10) contains better support for these adapters, which should make them easier to use. I currently have a single-GPU machine (it is an Nvidia adapter) with dual monitor outputs. I would like to add the DisplayLink adapter to drive a third external monitor. How can I set this up on Ubuntu 12.10?

  • Professional Development – Difference Between Bio, CV and Resume

    - by Pinal Dave
    Applying for work can be very stressful – you want to put your best foot forward, and it can be very hard to sell yourself to a potential employer while highlighting your best characteristics and answering questions.  On top of that, some jobs require different application materials – a biography (or bio), a curriculum vitae (or CV), or a resume.  These things seem so interchangeable, so what is the difference? Let’s start with the one most of us have heard of – the resume.  A resume is a summary of your job and education history.  If you have ever applied for a job, you will have used a resume.  The ability to write a good resume that highlights your best characteristics and emphasizes your qualifications for a specific job is a skill that will take you a long way in the world.  For such an essential skill, unfortunately it is one that many people struggle with. RESUME So let’s discuss what makes a great resume.  First, make sure that your name and contact information are at the top, in large print (slightly larger font than the rest of the text, size 14 or 16 if the rest is size 12, for example).  You need to make sure that if you catch the recruiter’s attention and they know how to get a hold of you. As for qualifications, be quick and to the point.  Make your job title and the company the headline, and include your skills, accomplishments, and qualifications as bullet points.  Use good action verbs, like “finished,” “arranged,” “solved,” and “completed.”  Include hard numbers – don’t just say you “changed the filing system,” say that you “revolutionized the storage of over 250 files in less than five days.”  Doesn’t that sentence sound much more powerful? Curriculum Vitae (CV) Now let’s talk about curriculum vitae, or “CVs”.  A CV is more like an expanded resume.  The same rules are still true: put your name front and center, keep your contact info up to date, and summarize your skills with bullet points.  However, CVs are often required in more technical fields – like science, engineering, and computer science.  This means that you need to really highlight your education and technical skills. Difference between Resume and CV Resumes are expected to be one or two pages long – CVs can be as many pages as necessary.  If you are one of those people lucky enough to feel limited by the size constraint of resumes, a CV is for you!  On a CV you can expand on your projects, highlight really exciting accomplishments, and include more educational experience – including GPA and test scores from the GRE or MCAT (as applicable).  You can also include awards, associations, teaching and research experience, and certifications.  A CV is a place to really expand on all your experience and how great you will be in this particular position. Biography (Bio) Chances are, you already know what a bio is, and you have even read a few of them.  Think about the one or two paragraphs that every author includes in the back flap of a book.  Think about the sentences under a blogger’s photo on every “About Me” page.  That is a bio.  It is a way to quickly highlight your life experiences.  It is essentially the way you would introduce yourself at a party. Where a bio is required for a job, chances are they won’t want to know about where you were born and how many pets you have, though.  This is a way to summarize your entire job history in quick-to-read format – and sometimes during a job hunt, being able to get to the point and grab the recruiter’s interest is the best way to get your foot in the door.  Think of a bio as your entire resume put into words. Most bios have a standard format.  In paragraph one, talk about your most recent position and accomplishments there, specifically how they relate to the job you are applying for.  If you have teaching or research experience, training experience, certifications, or management experience, talk about them in paragraph two.  Paragraph three and four are for highlighting publications, education, certifications, associations, etc.  To wrap up your bio, provide your contact info and availability (dates and times). Where to use What? For most positions, you will know exactly what kind of application to use, because the job announcement will state what materials are needed – resume, CV, bio, cover letter, skill set, etc.  If there is any confusion, choose whatever the industry standard is (CV for technical fields, resume for everything else) or choose which of your documents is the strongest.

  • Audiobooks for programmers?

    - by Zoot
    I'm a programmer with a two-hour round trip commute to work each day. I'd like to fill some of that time with audiobooks about software development. Any audiobooks that would help me become a better programmer would be appreciated. I'm thinking that books about design patterns and non-fiction about computing history might be good here, but I'm open to anything. Keeping in mind that I will be listening to this in a car, what are the best audiobooks that I can listen to? EDIT: Many people have also suggested podcasts. This is appreciated, but since podcasts arrive in a constantly arriving stream of data rather than as a finite amount of data, ways to juggle all of these different content streams would also be appreciated. To be more specific to my situation, my commuting vehicle has an MP3 CD player, USB input for MP3 files, and AUX input. I own Android and webOS devices that can be plugged into the AUX input.

  • Object Oriented programming on 8-bit MCU Case Study

    - by Calvin Grier
    I see that there's a lot of questions related to OO Programming here. I'm actually trying to find a specific resource related to embedded OO approaches for an 8 bit MCU. Several years back (maybe 6) I was looking for material related to Object Oriented programming for resource constrained 8051 microprocessors. I found an article/website with a case history of a design group that used a very small RAM part, and implemented many Object based constructs during their C design and development. I believe it was an 8051. The project was a success, and managed to stay inside the very small ROM/RAM they had available. I'm attempting to find it again, but Google can't locate it. The article was well written, and recommended a "mixed" approach using C methods for inheritance and encapsulation - if I recall correctly. Can anyone help me locate this article?

  • MTP Won't Work With Newer Ubuntu

    - by spacesword
    I have a Philips GoGear Vibe 4 GB, set to MTP mode, as it's always been. This works fine with older versions of Ubuntu and works fine with Windows, but doesn't work with newer versions of Ubuntu. The version history is like this: 12.04 - works 12.10 - works 13.04 - doesn't work 14.04 - doesn't work Windows 7 - works When you plug the MP3 player in Ubuntu the file manager opens the root of the device, which contains the folder "internal storage". When you click on "internal storage" to open it, the file manager just hangs. And if you try to unmount the MP3 player, that process hangs too, until you just unplug it. In Windows when you click on internal storage, it opens and shows all the files it contains. And in the earlier versions of Ubuntu it just worked. Any ideas? Thanks.

  • Is software innovation still primarily North American and European? Why, and for how much longer?

    - by limist
    Since this site is read by a global audience of programmers, I want to know if people generally agree that the vast majority of software innovation - languages, OS, tools, methodologies, books, etc. - still originates from the USA, Canada, and the EU. I can think of a few exceptions, e.g. Nginx webserver from Russia and the Ruby language from Japan, but overwhelmingly, the software I use and encounter daily is from North America and the EU. Why? Is history and historical momentum (computing having started in USA and Europe) still driving the industry? And/or, is some nebulous (or real) cultural difference discouraging software innovation abroad? Or are those of us in the West simply ignorant of real software innovation going on in Asia, South America, Eastern Europe, etc.? When, if ever, might the centers of innovation move out of the West? Your experiences and opinions welcome, thanks!

  • Licensing approach for .NET library that might be used desktop / web-service / cloud environment

    - by Bobrovsky
    I am looking for advice how to architect licensing for a .NET library. I am not asking for tool/service recommendations or something like that. My library can be used in a regular desktop application, in an ASP.NET solution. And now Azure services come into play. Currently, for desktop applications the library checks if the application and company names from the version history are the same as the names the key was generated for. In other cases the library compares hardware IDs. Now there are problems: an Azure-enabled web-application can be run on different hardware each time (AFAIK) sometimes the hardware ID for the same hardware changes unexpectedly checking the hardware ID or version info might not be allowed in some circumstances (shared hosting for example) So, I am thinking about what approach I can take to architect a licensing scheme that: is friendly to customers (I do not try to fight piracy, but I do want to warn the customer if he uses the library on more servers than he paid for) can be used when there is no internet connection can be used on shared hosting What would you recommend?

  • Did Blowing Into Nintendo Cartridges Really Help?

    - by Jason Fitzpatrick
    Anyone old enough to remember playing cartridge-based games like those that came with the Nintendo Entertainment System or its successors certainly remembers how blowing across the cartridge opening always seemed to help a stubborn game load–but did blowing on them really help? Mental Floss shares the results of their fact finding mission, a mission that included researching the connection mechanism in the NES, talking to Frank Viturello (who conducted an informal study on the effects of moisture on cartridge connectors), and otherwise delving into the history of the phenomenon. The most interesting part of the analysis, by far, is their explanation of how blowing on the cartridge didn’t do anything but the ritual of removing the cartridge to blow on it did.

  • Is reference to bug/issue in commit message considered good practice?

    - by Christian P
    I'm working on a project where we have the source control set up to automatically write notes in the bug tracker. We simply write the bug issue ID in the commit message and the commit message is added as a note to the bug tracker. I can see only a few downsides for this practice. If sometime in the future the source code gets separated from the bug tracking software (or the reported bugs/issues are somehow lost). Or when someone is looking in the history of commits but doesn't have access to our bug tracker. My question is if having a bug/issue reference in the commit message is considered good practice? Are there some other downsides?
