  • How To Enable 3D Acceleration and Use Windows Aero in VirtualBox

    - by Chris Hoffman
    VirtualBox’s experimental 3D acceleration allows you to use Windows 7’s Aero interface in a virtual machine. You can also run older 3D games in a virtual machine – newer ones probably won’t run very well. If you installed Windows 7 in VirtualBox, you may have been disappointed to see the Windows 7 Basic interface instead of Aero – but you can enable Aero with a few quick tweaks.

  • Computer Science Fundamentals - Recommended books

    - by contactmatt
    Hey, I'm looking to see if anyone can recommend any books in fundamentals of computer science. I obtained my associates degree as a programmer/analyst a couple years ago and I know a good amount about programming on the .NET framework. I'm even certified on the .NET 4 framework as a web application developer. However, since I was only able to obtain my associates degree, I was deprived at my college on the low-level basics and operations of computers and basic computer science information. I'm really interesting in learning about the low-level operations of a computer and in programming (bytes, bits, memory management, etc.) Can anyone recommend any good computer science books for someone who is decently experienced in programming? Thank You

  • Hacking Windows 7 Phone

    So here is the Hack of the Week. For those who have had their heads in the closet and haven't heard Microsoft is coming out with this Windows Phone 7 - the mythical vapor ware for a number of years now has been made public. Like many Silverlight geeks especially we are estatic as this phone now public will run Silverlight as the primary way to develop applications for it. On the downside if you installed the developer kit, the VM for the phone lacks pretty much... um... everything... no sensors,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Open Source Shopping Cart Software

    - by Cecil
    Ive come into a bit of an issue lately regarding shopping cart software, and i would like some recommendations. I have been an OsCommerce developer for years now, and im finding alot of my clients are wanting updated looking backends ... OSC is fantastic, but the fact that its not being updated anymore and that its clunky and table based is taking up quite a bit of my time. I have built a few sites on Magento, and although it gives quite a good backend, it is the slowest shopping cart i have ever come across in my time, that and the fact that modifying it takes years, has convinced me not to use that again. So, i like any input as to what people are finding good in todays open source shopping cart software.

  • De nouvelles informations sur Windows 8 et son Windows Server associé révélées au compte goutte par

    Mise à jour du 10.06.2010 par Katleen De nouvelles informations sur Windows 8 et son Windows Server associé révélées au compte goutte par un cadre de Microsoft Si l'on se réfère au cycle de vie des produits de Microsoft, on constate qu'au niveau des clients et des serveurs d'OS les sorties alternent entre une majeure, puis une mineure, et ainsi de suite, tous les deux ans. La mise à jour la plus récente de la version serveur de Windows 7 s'appelle Windows Server 2008 R2, et elle était mineure (sortie en 2009). On peut donc logiquement s'attendre à des changements majeurs pour la prochaine mouture. Dans une interview récente, Bob Muglia, Président de l'unité Tools and Servers chez Micr...

  • Silverlight: Creating great UIs

    - by xamlnotes
    I was always told I was left brained and could not draw. And I bought into that view. Somewhere down the road years ago I did learn to play guitar and to play by ear at that.  Now that’s not all left brained so my right brain must be working.  About a year ago, my good friend Billy Hollis turned me own to a book by Betty Edwards (http://www.drawright.com/).  I started reading this and soon I found my self drawing on napkins in restaurants while we were waiting on food and at many other times too.  Dang’d if I could not draw! Check out my UI article at Dev Pro Connections (Great UIs article) on some of my experiences. Heres a few more links that are really cool too. Cool color combinations web site Simply painting is awesome. Saw this guy on tv. This site has some great tools for color contrasting

  • How do you coordinate with interaction designers during implementation?

    - by Alex Feinman
    Programmers are largely responsible for helping move a product from design to implementation. This process is always full of snags: implementation details rear their ugly head and make parts of the design infeasible user feedback on early prototypes leads to changes in the design new technologies alter the field of what is possible, bringing back designs previously thought impossible priorities shift, schedules change, and requirements wander How do you keep design and implementation in contact during the implementation? What processes do you use? Tools? Artifacts? Guidelines? Communication strategies?

  • Is agile about development or management?

    - by ashy_32bit
    On a debate over what Scrum is all about, I found that perhaps I totally misunderstood the agile thing. It appears to me that Scrum (which is certainly considered an Agile process) is all about managing features and sprints and roles and stuff with nothing to do with TDD, pair programming, CI, refactoring and other developer centric techniques and practices that I though (until now) are the heart of agile. Now I am facing a difficulty ! 1) Is Scrum agnostic to whether developers do agile practices? 2) Can you implement Scrum in a team that does not utilize automated tests? does not perform refactoring or does not adhere to the agile programming practices?

  • How to use short breaks at work effectively for self-development?

    - by Alaudo
    At the moment my daily work as a developer requires me to have short 10-20 min breaks after every 2-3 hours. It would be nice if I could use those effectively to improve my expertise in programming or CS in general. I tried several things: Reading jokes online gets boring very soon. Trying to solve some (even the most simple) tasks from different code contests requires more time, as long as I have some idea of an algorithm the time is over. Reading a randomly picked Wikipedia-article about Computer Science: depending upon the article sometimes it requires more time and is not an easy reading for a break. So, I ended up reading StackOverflow questions and answers with most votes: that is entertaining and educative. Do you have any other suggestions?

  • 0.00006103515625 GB of RAM. Is .NET MicroFramework part of Windows CE?

    - by Rocket Surgeon
    The .NET MicroFramework claims to work on 64K RAM and has list of compatible targets vendors. At the same time, same vendors who ship hardware and create Board Support Packages (vendors like Adeneo) keep releasing something named Windows 7 CE BSP for the same hardware targets. Obviously the OS as heavy as WinCE needs more than 64K RAM. So, somehow .NET MicroFramework is relevant to WinCE, but how ? Is it part of bigger OS or is it base of it, or are both mutually exclusive ? Background: 0.00006103515625 GByte of RAM is same as 64Kbyte of RAM. I am looking for possiblity to use Microsoft development tools for small target like BeagleBone. http://www.adeneo-embedded.com/About-Us/News/Release-of-TI-BeagleBone Nice. Now .. where is a MicroFramework for the same beaglebone ? Is it inside the released pile ?

  • MODX based site has been compromised, and tagged by Google as malware

    - by JAG2007
    I'm the webmaster (inherited the site from the developer) for a site called kenbrook.org. The site is currently being tagged as malware infected by Google, and gives the following details: http://www.google.com/safebrowsing/diagnostic?site=kenbrook.org Sadly, this is the second time it has occurred. I posted the issue when it happened last year originally on Stackoverflow on this post, shortly after I inherited the site. At the time the fix was a simple removal of a few lines of code from a .js file, but I never did discover or resolve the vulnerability. The site is built on MODX, which neither I, nor the original builder, have any familiarity with. I've tried to check for security updates from MODX, but updating that software has been a real pain also. Sooo...what's my next step to getting this whole issue resolved? Or steps?

  • Removing AppPrincipals from Office365

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information So here is an annoying issue. If I have your AppPrincipal and secret, I can party as you! But as we go through our usual dev cycles, we create these ApplicationIDs. Hell Visual Studio will create them for us, to make things easy!The problem is, many a developer, and some a ITOgre, may leave these AppPrincipalIds sitting there and not clean them up when they are done playing. You can look for currently registered App Principals at https://yourtenant/_layouts/15/appprincipals.aspx The problem is, that URL shows you App Principals registered AND currently in use. Currently NOT in use App Principals are NOT shown on that page. The same issue applies on premises also, even though here I am talking specifically about Office 365. Getting rid of these in On-Prem is easy, just use the Object model (server side). Read full article ....

  • Knowing your user is key--Part 1: Motivation

    - by erikanollwebb
    I was thinking where the best place to start in this blog would be and finally came back to a theme that I think is pretty critical--successful gamification in the enterprise comes down to knowing your user.  Lots of folks will say that gamification is about understanding that everyone is a gamer.  But at least in my org, that argument won't play for a lot of people.  Pun intentional.  It's not that I don't see the attraction to the idea--really, very few people play no games at all.  If they don't play video games, they might play solitaire on their computer.  They may play card games, or some type of sport.  Mario Herger has some great facts on how much game playing there is going on at his Enterprise-Gamification.com website. But at the end of the day, I can't sell that into my organization well.  We are Oracle.  We make big, serious software designed run your whole business.  We don't make Angry Birds out of your financial reporting tools.  So I stick with the argument that works better.  Gamification techniques are really just good principals of user experience packaged a little differently.  Feedback?  We already know feedback is important when using software.  Progress indicators?  Got that too.  Game mechanics may package things in a more explicit way but it's not really "new".  To know how to use game mechanics, and what a user experience team is important for, is totally understanding who our users are and what they are motivated by. For several years, I taught college psychology courses, including Motivation.  Motivation is generally broken down into intrinsic and extrinsic motivation.  There's intrinsic, which comes from within the individual.  And there's extrinsic, which comes from outside the individual.  Intrinsic motivation is that motivation that comes from just a general sense of pleasure in the doing of something.  For example, I like to cook.  I like to cook a lot.  The kind of cooking I think is just fun makes other people--people who don't like to cook--cringe.  Like the cake I made this week--the star-spangled rhapsody from The Cake Bible: two layers of meringue, two layers of genoise flavored with a raspberry eau de vie syrup, whipped cream with berries and a mousseline buttercream, also flavored with raspberry liqueur and topped with fresh raspberries and blueberries. I love cooking--I ask for cooking tools for my birthday and Christmas, I take classes like sushi making and knife skills for fun.  I like reading about you can make an emulsion of egg yolks, melted butter and lemon, cook slowly and transform them into a sauce hollandaise (my use of all the egg yolks that didn't go into the aforementioned cake).  And while it's nice when people like what I cook, I don't do it for that.  I do it because I think it's fun.  My former boss, Ultan Ó Broin, loves to fish in the sea off the coast of Ireland.  Not because he gets prizes for it, or awards, but because it's fun.  To quote a note he sent me today when I asked if having been recently ill kept him from the beginning of mackerel season, he told me he had already been out and said "I can fish when on a deathbed" (read more of Ultan's work, see his blogs on User Assistance and Translation.). That's not the kind of intensity you get about something you don't like to do.  I'm sure you can think of something you do just because you like it. So how does that relate to gamification?  Gamification in the enterprise space is about uncovering the game within work.  Gamification is about tapping into things people already find motivating.  But to do that, you need to know what that user is motivated by. Customer Relationship Management (CRM) is one of those areas where over-the-top gamification seems to work (not to plug a competitor in this space, but you can search on what Bunchball* has done with a company just a little north of us on 101 for the CRM crowd).  Sales people are naturally competitive and thrive on that plus recognition of their sales work.  You can use lots of game mechanics like leaderboards and challenges and scorecards with this type of user and they love it.  Show my whole org I'm leading in sales for the quarter?  Bring it on!  However, take the average accountant and show how much general ledger activity they have done in the last week and expose it to their whole org on a leaderboard and I think you'd see a lot of people looking for a new job.  Why?  Because in general, accountants aren't extraverts who thrive on competition in their work.  That doesn't mean there aren't game mechanics that would work for them, but they won't be the same game mechanics that work for sales people.  It's a different type of user and they are motivated by different things. To break this up, I'll stop here and post now.  I'll pick this thread up in the next post. Thoughts? Questions? *Disclosure: To my knowledge, Oracle has no relationship with Bunchball at this point in time.

  • What would you think of a job based on mostly doing the proof of concept?

    - by davsan
    I'm working as a developer in a small software company whose main job is interfacing between separate applications, like between a telephony system and an environment control system, between IP TVs and hospitality systems, etc...And it seems like I am the candidate for a new job title in the company, as the person who does the proof of concept of a new interfacing project and does some R&D for prototyping. What do you think the pros and cons of such a job would be, considering mainly the individual progress/regress of a person as a software engineer? And what aspects would you consider essential in a person to put him/her in such a job position?

  • How can I get the business analysts more involved in BDD?

    - by Robert S.
    I am a proponent of Behavior Driven Development, mainly with Cucumber and RSpec, and at my current gig (a Microsoft shop) I am introducing SpecFlow as a tool to help with testing. I'd like to get the business analysts on my team involved in writing the features and scenarios, but they are put off by the "technical" aspect of it, meaning creating the files in Visual Studio (or even having Visual Studio on their machines). They want to know if we can put all the scenarios for a feature in Jira. What I'm looking for is suggestions for a workflow that will work well with BA types that are accustomed to project management/work tracking tools like Jira (we also use Greenhopper).

The key takeaway away of the talk for me was doing a lot with really simple tools. While many teams are moving on to more complex ecosystems, YouTube really does keep it simple. They program primarily in Python, use MySQL as their database, they’ve stuck with Apache, and even new features for such a massive site start as a very simple Python program. That doesn’t mean YouTube doesn’t do cool stuff, they do, but what makes everything work together is more a philosophy or a way of doing things than technological hocus pocus. What made YouTube into one of the world’s largest websites? Read on and see... Stats @font-face { font-family: "Arial"; }@font-face { font-family: "Cambria"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: "Times New Roman"; }div.Section1 { page: Section1; } 4 billion Views a day 60 hours of video is uploaded every minute 350+ million devices are YouTube enabled Revenue double in 2010 The number of videos has gone up 9 orders of magnitude and the number of developers has only gone up two orders of magnitude. 1 million lines of Python code Stack @font-face { font-family: "Arial"; }@font-face { font-family: "Cambria"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: "Times New Roman"; }div.Section1 { page: Section1; } Python - most of the lines of code for YouTube are still in Python. Everytime you watch a YouTube video you are executing a bunch of Python code. Apache - when you think you need to get rid of it, you don’t. Apache is a real rockstar technology at YouTube because they keep it simple. Every request goes through Apache. Linux - the benefit of Linux is there’s always a way to get in and see how your system is behaving. No matter how bad your app is behaving, you can take a look at it with Linux tools like strace and tcpdump. MySQL - is used a lot. When you watch a video you are getting data from MySQL. Sometime it’s used a relational database or a blob store. It’s about tuning and making choices about how you organize your data. Vitess- a  new project released by YouTube, written in Go, it’s a frontend to MySQL. It does a lot of optimization on the fly, it rewrites queries and acts as a proxy. Currently it serves every YouTube database request. It’s RPC based. Zookeeper - a distributed lock server. It’s used for configuration. Really interesting piece of technology. Hard to use correctly so read the manual Wiseguy - a CGI servlet container. Spitfire - a templating system. It has an abstract syntax tree that let’s them do transformations to make things go faster. Serialization formats - no matter which one you use, they are all expensive. Measure. Don’t use pickle. Not a good choice. Found protocol buffers slow. They wrote their own BSON implementation, which is 10-15 time faster than the one you can download. ...Contiues. Read the blog Watch the video

  • Is it common to purchase an insurance policy for contract development work?

    - by Matthew Patrick Cashatt
    I am not sure if this is the best place for the question, but I am not sure where else to ask. Background I am a contract developer and have just been asked to provide a general liability policy for my next gig. In 6-7 years this has never been asked of me. Question Is this common? If so, can anyone recommend a good underwriter that focuses on what we do as contract software developers? I realize that Google could help me find underwriters but it won't give me unbiased public opinion about which companies actually understand what we do and factor that into the price of the policy. Thanks, Matt

  • SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

    - by Chris Tomkins
    One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.

  • Could someone help me understand SQL TDE Database encryption?

    - by SLC
    I don't quite follow how it works. According to the MSDN Article there is a big hierarchy of keys protecting other keys and passwords. At some point the database is encrypted. You query the database which is encrypted, and it works seamlessly. If you're able to simply connect to the database as normal and not have to worry about any of the encryption from a developer point of view, how exactly is it secure? Surely anyone can simply connect and do select * from x and the data is revealed. Sorry my question is a bit scattered, I am just very confused by the article.

  • Are Remote commit hooks in subversion possible?

    - by John Hamelink
    Hi there, my current setup is as follows: We have a Linux samba share that contains all the repository folders (with the hooks folder inside, amongst the others) All the developers have the share mapped as a network drive, and import to a local directory (normally C:\Server\RepositoryName) where they work on their files. All the machines accessing the drive (unfortunately) run windows. What I'm aiming to do is to have a hook on the Linux server that detects when a commit has been made, by which project, the revision number, the name of the developer who committed, etc. I looked into the hooks files, but they seem to be ran by the client. Is there a way to monitor svn changes and collect the relevant information from the Linux server?
