  • Turn your laptop into a wireless Access Point with Windows 7!

    - by David Nudelman
    Windows 7 offers a very cool feature where you can connect multiple devices to any wired and wireless network connection (hotel, cable, 3G, UMTS, EDGE, WIFI, RJ45, Ethernet, etc.) by turning your own laptop into a wireless AP (Access Point) to relay those devices not directly connected to the internet. For this just enter these two commands to an elevated (right click on CMD.EXE, run as administrator): netsh wlan set hostednetwork mode=allow ssid=YOURFRIENDLYSSID key=SOMEPASSWORD netsh wlan start hostednetwork At this point, if Internet Connection Sharing (ICS) is setup, anyone can connect to your SoftAP (if they know the PWD of course) and the traffic will be sent through whatever adapter you want. You can actually bridge it across an entirely different adapter... or the same on a different Wifi LAN. A GUI to set this up can be downloaded for free here: http://www.connectify.me/

  • What should be allowed inside getters and setters?

    - by Botond Balázs
    I got into an interesting internet argument about getter and setter methods and encapsulation. Someone said that all they should do is an assignment (setters) or a variable access (getters) to keep them "pure" and ensure encapsulation. Am I right that this would completely defeat the purpose of having getters and setters in the first place and validation and other logic (without strange side-effects of course) should be allowed? When should validation happen? When setting the value, inside the setter (to protect the object from ever entering an invalid state - my opinion) Before setting the value, outside the setter Inside the object, before each time the value is used Is a setter allowed to change the value (maybe convert a valid value to some canonical internal representation)?

  • Best Web Site Copying Software

    - by GregH
    I just wanted to get some opinions on the best "web site copying" software out there (free or commercial is fine). I have a site that I've recently become responsible for managing, and the previous consultant has not provided operating system access. As such, the plan is to re-host the web site. I realize there are a lot of different issues to consider in doing this. However, I don't have much choice in the matter now. The plan is to use web site copying software (ala HTTrack) to "rip" the web site, and then modify what is downloaded back in to a maintainable site. This, of course, involves HTML, css, javascript, etc on the front-end. I'd like to recover as much of the site as possible to make re-creating it as easy as possible.

  • Day 1 - Finding Like Minds

    - by dapostolov
    So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

  • A human-friendlier Samba name mangling

    - by Alex
    Most of our computers run Ubuntu, but two of them dual-boot into Windows, and when we have guests over, they typically also run Windows computers. Thus, in addition to using NFS, our file server (Ubuntu server) also runs Samba. And since we use Ubuntu mostly, we like to take advantage of its advantages over Windows, such as being able to use the characters \:*?"<>| in a file name. The problem, of course, is that Windows doesn't accept those characters in file names, and so Samba has to translate the file name into something more acceptable. The way it does this, however, I find to be obnoxious. The file name Episode 182 - Exorcist 2: The Heretic.mp4 for instance turns into E4Q82R~Y.MP4. This is a terrible "correction". Is there a way to make Samba's mangling a little more friendly to humans? Is possible to "correct" it to something like Episode 182 - Exorcist 2_ The Heretic.mp4 instead, where the illegal characters are simply substituted?

  • Should I implement slugs with my already fairly long URLs?

    - by Earlz
    I'm considering implementing slugs in my blog. My blog uses MongoDB. One of the side-effects of using MongoDB is that it uses relatively long hex string IDs. Example before: http://lastyearswishes.com/blog/view/5070f025d1f1a5760fdfafac after: http://lastyearswishes.com/blog/view/5070f025d1f1a5760fdfafac/improvements-on-barelymvc Of course, that's a relatively short title.. I have some longer ones, but intend to limit the maximum character limit for slugs to something reasonable. At what point does a URL become so long that it hurts SEO instead of improves it? In this case, should I leave my URLs alone, or add slugs?

  • Website content copied - How can I prove that I wrote it?

    - by Remy
    One of our competitors constantly copies all our website content. Now, I assume the trouble is to proof that we wrote the content first and that it is not the other way round. I checked on http://www.archive.org, but there is nothing. Any other way to proof that? FYI: We are a swiss company, so different laws will apply. Solution: [Found later] You can upload your content to this service and that they basically timestamp it. https://myows.com/ Another way we found, is to just print out your copy/design, etc. put it into an envelop and send it to ourself (without actually opening it later of course).

  • Web services, Java EE, Spring, DB integration project ideas - maybe data mining related?

    - by saral jain
    I am a graduate Computer Science student (Data Mining and Machine Learning) and have good exposure to core Java (3 years). I have read up on a bunch of stuff on the following topics: Design patterns, Java EE Web services (SOAP and REST), Spring, and Hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff -- over my free time of course -- to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + SVN, maven). Any good project ideas would be really appreciated. I just want to build this stuff to learn, so I don't really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus as it fits with my research but is absolutely not necessary since this project is more to learn to do large scale software development.

  • What happens if you're unable to solve a problem?

    - by gablin
    I'm a year away from graduating from university, and I'm really looking forward to solving practical problems. Especially non-trivial ones which require a bit of research and a lot of thinking. But at the same time, that is also my greatest fear - being faced with a problem that I'm unable to solve, no matter how hard I try. And with pressure to deliver code on impending deadlines just around the corner, it does look a bit scary when viewing it from the safe playgrounds on uni (where the worst thing that can happen is that you have to redo a course or exam). So for those who have been in industry for any longer length of time, what would happen if you were told to solve a problem that you couldn't? Has it happened, and if so, what did happen? Did they just drop it and said "Oh well, guess we can make do with something else"? Were there consequences? Were you reprimanded, or even fired?

  • Car Modelling for race game

    - by Mert Toka
    I am taking Computer Graphics course this semester and we have a video game competition. I am making racing game with simulated dynamics. Our professor told us that we don't have to do much of a modelling but since we haven't started the gaming part and since I have free time I want to model the car. My question is firstly which software do you recommend to design game components? I know Maya right now. Secondly, if I design the car or any other part, what should its polygon count in order to run game smoothly? I can design pretty much everything but I assume that it is hard to design low-poly models.

  • Restore database to the point of disaster

    - by TiborKaraszi
    This is really basic, but so often overlooked and misunderstood. Basically, we have a database, and something goes south. Can we restore all the way up to that point? I.e., even if the last backup (db or log) is earlier than the disaster? Yes, of course we can (unless for more extreme cases, read on), but many don't realize/do that, for some strange reason. This blog post was inspired from a thread in the MSDN forums, which exposed just this misunderstanding. Basically the scenario was that they...(read more)

  • Books or help on OO Analysis

    - by Pat
    I have this course where we learn about the domain model, use cases, contracts and eventually leap into class diagrams and sequence diagrams to define good software classes. I just had an exam and I got trashed, but part of the reason is we barely have any practical material, I spent at least two good months without drawing a single class diagram by myself from a case study. I'm not here to blame the system or the class I'm in, I'm just wondering if people have some exercise-style books that either provide domain models with glossaries, system sequence diagrams and ask you to use GRASP to make software classes? I could really use some alone-time practicing going from analysis to conception of software entities. I'm almost done with Larman's book called "Applying UML and Patterns An Introduction to Object-Oriented Analysis and Design and Iterative Development, Third Edition". It's a good book, but I'm not doing anything by myself since it doesn't come with exercises. Thanks.

  • What is the correct way to handle debug output in Java?

    - by Federico Zancan
    As my current Java projects grow bigger and bigger, I feel a likewise growing need to insert debug output in several points of my code. To enable or disable this feature appropriately, depending on the opening or closure of the test sessions, I usually put a private static final boolean DEBUG = false at the beginning of the classes my tests are inspecting, and trivially use it this way (for example): public MyClass { private static final boolean DEBUG = false; ... some code ... public void myMethod(String s) { if (DEBUG) { System.out.println(s); } } } and the like. But that doesn't bliss me out, because of course it works but there could be too many classes in which to set DEBUG to true, if you are not staring at just a couple of them. Conversely, I (like - I think - many others) wouldn't love to put the whole application in debug mode, as the amount of text being output could be overwhelming. So, is there a correct way to architecturally handle such situation or the most correct way is to use the DEBUG class member?

  • Resources for popular domain models

    - by Songo
    I have come across many situations where I had to build a system for a library or a clinic or other popular domains. The thing is a domain model for a library was probably done 1000 times already with different level of details of course. Here is an example. Is there a popular website or community where one can find ready made domain models for popular systems? The whole purpose I'm trying to achieve is to quickly get a grasp of the domain I'm modeling and customize it to my needs. Re-inventing the wheel seems really absurd when the same system might have been modeled properly previously. Note I know Google might sound like the perfect source, but there is a repository out there that people can post there models, so that others can share them.

  • org.openide.awt.ColorComboBox

    - by Geertjan
    It's the time of year when a lot of NetBeans Platform tutorials are being reviewed, revised, and rewritten. Today I'm looking at the NetBeans Platform Paint Application Tutorial. Suddenly I remembered seeing something in a recent API Changes document about a new class, ColorComboBox. That means I can make the tutorial a lot simpler, since Tim Boudreau's external ColorChooser.jar is now superfluous. Here's what the ColorComboBox looks like: It works perfectly. Of course, the nice thing about using that JAR was that it showed the user how to incorporate external JARs, but I'll make sure to make a note of that in the tutorial, along the lines of "If you don't like the NetBeans Platform color combobox, and would like to replace it with your own, such as Tim's ColorChooser.jar or a JavaFX color chooser, take the following steps." In short, if you're using NetBeans APIs, write this on your ceiling above your bed: http://bits.netbeans.org/dev/javadoc/apichanges.html, check that page regularly (mark it in your calendar to do first thing every Monday morning) and you'll be aware of the latest changes as they happen.

  • Jazz up your web forms using jQuery animation effects

    - by bipinjoshi
    In this part I cover how to add jazz to your web forms using jQuery effects. jQuery provides a set of methods that allow you to create animations in your web pages. Collectively these methods are called as Effects. The effects they render include fading in and out, sliding in and out, changing opacity of elements, hiding and showing elements and so on. You can, of course, define custom animations. In this part we will use these effects to develop a tooltip, master-detail listing and progress indicator.http://www.bipinjoshi.net/articles/9b1f4a81-ae07-4859-8ff2-067e5887adbd.aspx

  • Convert Docx or Odt to Pdf

    - by luxifer
    Hi there, I need to find a way to convert docx or odt files to pdf on a linux web server. Therefore I'm not willing to install openoffice.org for obvious reasons. I've tried Google but it failed for me, so I'm here :-) I can't imagine there's no other solution to this problem than to install a huge chunk of binaries given that a) there are (or at least should be) lot's of packages which can read docx or at least odt and b) there are as many packages which can write pdf files What am I missing here? scratching head Regards, luxifer ps edit: I don't want to use a web service - neither free or paid edit 2: at this point it would also help to convert the docx back to doc so I could use wvpdf to generate the pdf... edit 3: of course it would also help if i could do search and replace on a doc file in the first place; or xps for that matter

  • History of open source software

    - by Victor Sorokin
    I've been always interested, out of the pure self-amusement, in the history of open software used today: who were the people which started it and what were the reasons to start what were design decisions at the start how software evolved over the time Specifically, I'm interested in following software: GCC X Linux kernel Java Of course, there is plenty of information in Internet to google for, but I thought it would be nice to have list of interesting resources at this site. I hope some of visitors of this site have similar interest and can share a link or two they found particularly amusing/interesting. To make this entry more question-like, here's straight question: what are the most interesting/amusing links about history of open source software?

  • JDeveloper and Upgrading Your JDK on Ubuntu

    - by Duncan Mills
    One little gotcha, if you, as I did recently, upgrade your JDK on Ubuntu then you may have to make sure you reflect that change in a couple of places for JDeveloper to stay happy. Assuming that you've installed from the jar version of the JDeveloper installer, then the JDK that you specified at install time will be recorded in the .jdev_jdk file in your home directory.However, be aware that this is not the only reference to the absolute path of the JDK. When you run the embedded WebLogic for the first time then the .jdeveloper/system11.1.1.3.37.56.60/DefaultDomain/bin/startWebLogic.shscript will be created, and associated with that, the setDomainEnv.sh script in the same directory. So, if you do want to change the JDK location be sure to change this file as well. (or of course do everything with symbolic links)

  • Adding Bzr Launchpad PPA to Ubuntu Hardy

    I've got TortoiseBazaar installed on my Windows laptop, and I was trying to branch a repository hosted on my VPS to another directory on my VPS, and I got this lovely error: bzr: ERROR: Unknown branch format: 'Bazaar Branch Format 7 (needs bzr 1.6) That lead me to this mailing-list archive: http://osdir.com/ml/bazaar/2009-06/msg00692.html Then I tried following the instructions here to add the Launchpad PPA to /etc/apt/sources.list, but they forgot to mention that you need to do this: sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com D702BF6B8C6C1EFD Which I found out about here after I got this error: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D702BF6B8C6C1EFD after modifying my /etc/apt/sources.list and running: sudo apt-get update Just thought I'd save someone else some pain. And of course, don't forget to uninstall the version of bzr that wouldn't play ball in the first place.
