• Security in a private web service

  - by Oni

  I am developing a web site and a web service for a small on-line game. Technically, I'll be using Express (node.js) and MongoDB+Redis for the databases. This the structure I came up with: One Express server that will server as the Web Service. This will connect to the databases. One Express server that will provide the web site. It will connect to the Web Service to retrieve and push the information. iOS and Android application will be able to interact with the WebService. Taking into account: It is a small game. The information transferred is not critical. There will NOT be third party applications. At least for the moment. My concern is about which level of security I should use in each of the scenarios: Security of the user playing through web browser Security of the applications and the Web Server connecting to the WS. I have take a look at the different options and: OAuth and/or Https is too much for this scenario, isn't it? Will be a good option to hash the user and password with MD5(or similar) and some salt? I would like to get some directions and investigate by my own rather than getting a response like "you should you use this node.js module..." Thanks in advance,

• How to search for a tester?

  - by MainMa

  As a freelance developer, a few times I tried to find some testers to be able to let them test my software/web applications. If I try to find them, it's because most of the customers are not intended to hire external testers and don't see why this can benefit to them, so products are UI-untested and buggy. I tried lots of things. Discussion boards for IT people, specific websites for people who search for a job. Every time I clearly precise that I'm looking for product testers. I completely failed to find anybody for this job. I found instead two types of people: Non IT people who try to qualify as testers, but don't have enough skills for that, and don't really know what testing is and how to do it, Programmers, who are skilled as programmers, but not as testers, and who mostly don't understand neither what testing is about (or think it's the same thing as code review, or it consists in writing unit tests). Of course, they submit general programmers resumes, where they describe their high experience in Assembler and C++, but don't tell anything about anything related to the job of a tester. What I'm doing wrong? Isn't it called "tester"? Is there at least a tester job, different from general programming job? Is there any precise requirement to require from each candidate which can eliminate non IT people and general programmers?

• How to deal with colleagues refuse to follow practices?

  - by Adrian Shum

  I was discussing with another colleague about what we should be used when an DB entity is referring to another. I don't think there is any good reason to break the practice of putting the Primary Key in the referring entity. However, one of my colleague says: "You should use a surrogate key in the entity, but it is better to put the human-readable natural key in the referring entity. As long it is unique, it is fine and it is easier when you are doing support or maintenance job" I know it will works, but obviously it is not a good practice you are putting a non-PK unique column as "foreign key", just for gaining a bit of ease in writing SQL during support as we can have less table join. Though I mentioned the his approach is conceptual incorrect, and causing problem too practically etc, he seems rather trade off correctness in data model in exchange of ease of maintenance. And he said: "I know it is not good practice, but good practice is not golden rule" Honestly I feel frustrated when dealing with something like this. I know there are always case that we should break some rule or practice, but doubtless it is not such case now. What will you when you are facing situation like this? Please assume yourself being a senior developer which is expected to contribute in misc development direction and convention.

• How to promote code reuse and documentation?

  - by Graviton

  As a team lead of about 10+ developers, I would want to promote code reuse. We have written a lot of code-- a lot of them are repetitive over the past few years. The problem now is that a lot of these code are just duplicate of some other code or a slight variation of them. I have started the movement ( discussion) on how to make code into components so that they can be reused for the future projects, but the problem is that I afraid the new developers or other developers who are ignorant of the components will just go forward and write their own thing. Is there anyway to remind the developers to reuse the components/ improve the documentation/ contribute to the underlying component instead of duplicating the existing code and tweaking on it or just write their own? How to make the components easily discover-able, easily usable so that everyone will use it? Edit: I think every developer knows about the benefit of reusable components and wants to use them, it's just that we don't know how to make them discoverable. Also, the developers when they are writing code, they know they should write reusable code but lack of the motivation to do so.

• C4C - 2012

  - by Timothy Wright

  C4C, in Kansas City, is always a fun event. At points it gets to be a pressure cooker as you zone in trying to crank out some fantastic code in just a few hours, but it is always fun. A great challenge of your skill as a software developer and for a good cause. This year my team helped The United Cerebral Palsy of Greater Kansas City organization to add online job applications and a database for tracking internal training. I keep finding that there is one key rule to pulling off a successful C4C weekend project, and that is “Keep It Simple”. Each time you want to add that one cool little feature you have to ask yourself.. Is it really necessary? and Do I have time for that? And if you are going to learn something new you should ask yourself if you’re really going to be able to learn that AND finish the project in the given time. Sometimes the less elegant code is the better code if it works. That said… You get a great amount of freedom to build the solution the way you want. Typically, the software we build for the charities will save them a lot of money and time and make their jobs easier. You are able to build the software you know you are capable of creating from your own ideas. I highly recommend any developers in the area to signup next year and show off your skills. I know I will!

• Researching runtime technologies (Xmas fun with HTML5)

  - by Eric Nelson

  The Internet Explorer 9.0 team just posted about Pirates love Daises. This is a showcase game for the power of HTML 5 running inside IE 9.0 – and the author has done a fantastic job (you can get more details from Grant’s blog post). A game developer is an ISV (Independent Software Vendor) – a B2C  ISV. In my role I don’t (typically) work with B2C ISVs, hence a reasonable question is “Why blog about it?”. I think applications like this demonstrate the power of HTML 5 and IE9 for delivering really rich user experiences which have the promise of working cross browser and cross platform - in the future as HTML5 capable browsers become the norm. Microsoft is investing heavily in implementing a great “run time” in IE9 if cross platform is an important requirement for your UX. And the other reason for blogging this… it is nearly Xmas and we all should be having a little more fun on the run in. Hence you can play with confidence that your defence to your manager is “I’m just researching a powerful runtime that Microsoft is working on which could be significant to our future B2B product directions” Play now (Needs HTML 5 browser such as IE9) Related Links: To install IE9 Beta or the Preview (which won’t replace your existing IE) check our the IE9 TestDrive center.

• Tabs Visual Manager Adds Thumbnailed Tab Switching to Chrome

  - by ETC

  If you rock a bunch of tabs and sometimes need a little visual reminder to recall where you left a tab you’re looking for, Tabs Visual Manager thumbnails all your tabs for easy visual switching. Install Tabs Visual Manager, restart Chrome, and anytime you need to find a tab you can click on the Tabs Visual Manager icon in the toolbar. By default it opens a new tab with all your tab thumbnails, we found it was more convenient to switch it to pop-up mode (wherein it pops up a smaller menu from the icon itself instead of a whole new tab). Tabs Visual Manager is a free extension and works wherever Chrome does. Hit up the link below to read more and grab a copy.

• Give Chromium-Based Browser Desktop Notifications a Native System Look in Ubuntu

  - by Asian Angel

  Desktop notifications from Chromium-based browsers are an awesome feature, but they do not blend in well at all with the native system theming in Ubuntu. Now you can fix that small problem using the wonderful Chromify-OSD extension created by Marco Ceppi. Once you get the extension installed you can give it a quick test run using the link and information we have listed below. As you can see in the image above the new notification style looks absolutely wonderful. Chromify-OSD (Chrome Web Store) [via OMG! Ubuntu!] You can test the new look of the notifications for yourself using the following webpage. Keep in mind that the extension needs to be installed first before this will work though. Note: Enter the following image URL into the Icon Blank (http://www.rgraph.net/images/logo.png) or the URL for an appropriate image, otherwise the notification may not work properly during your test.

• Debugging/Logging Techniques for End Users

  - by James Burgess

  I searched a bit, but didn't find anything particularly pertinent to my problem - so please do excuse me if I missed something! A few months back I inherited the source to a fairly-popular indie game project and have been working, along with another developer, on the code-base. We recently made our first release since taking over the development but we're a little stuck. A few users are experiencing slowdowns/lagging in the current version, as compared to the previous version, and we are not able to reproduce these issues in any of our various development environments (debug, release, different OSes, different machines, etc.). What I'd like to know is how can we go about implementing some form of logging/debugging mechanism into the game, that users can enable and send the reports to us for examination? We're not able to distribute debug binaries using the MSVS 2010 runtimes, due to the licensing - and wouldn't want to, for a variety of reasons. We'd really like to get to the bottom of this issue, even if just to find out it's nothing to do with our code base but everything to do with their system configuration. At the moment, we just have no leads - and the community isn't a very technically-savvy one, so we're unable to rely on 'expert' bug reports or investigations. I've seen the debug logging mechanism used in other applications and games for everything from logging simple errors to crash dumps. We're really at a loss at this stage as to how to address these issues, having been over every commit to the repository from the previous to the current version and not finding any real issues.

• The road to become a programmer [closed]

  - by user68991

  I'm looking for a 'career' change, I don't actually have a career at the moment since I haven't been able to find a job since I graduated with a degree in Materials Engineering. One of my loves has always been computers and programming, though I have never studied it seriously. When I was 11 I wrote a very basic graphical 'game' using notepad and HTML, where I drew each possible position of the main character on the different 'maze' level in MSPaint, using pictures of arrows as links to a new page with the character in a new position, and various other buttons would pop up 'search box', 'press button' etc. At the time I thought this was an amazing achievement of my programming skills. I've used a little bit of FORTRAN 90 whilst I was at university, which rekindled my interest in programming. When I was a kid I mainly used C and HTML, but only very basically as my 'game' suggests. I want to learn a new programming language, I'm not entirely sure where I want to go with it, but the number one contender at the moment is android apps. I'm looking at learning Java, but I've read that it's a difficult place to begin with; so I've also looked at learning Visual Basic, which I believe is also object oriented(?) but a little easier to understand? (not that I know what an object is anyway). Any information people could give me regarding which language to learn, and if there are any good online tutorial for that language I'd really appreciate it. Some of the tutorials I've used so far are full or jargon I can't understand. Also, I'm not afraid of maths having got an engineering degree. Thanks in advance for any help/advice. James

• Why ADF Developers Should Attend ODTUG This Year

  - by shay.shmeltzer

  If you are using Oracle ADF or planning to pick it up in the next year, I would encourage you to try and attend this year's ODTUG K-Scope conference. If you are not familiar with it, ODTUG - the Oracle Development Tools User Groups - holds a yearly conference that is very technical in nature. It is not a huge conference in terms of the number of attendees, but this just means that you have more opportunities to interact with Oracle ACEs, Oracle Product Managers, and other developers. The conference is known to be a no-fluff, no-marketing, technical conference. This year however there is one key new thing that should be of interest to readers of this blog. A new track called the "Fusion Middleware" track has been formed and it has lots of sessions for any level of ADF developer. The track is run by several Oracle ACEs who are also involved in the ADF Enterprise Methodology Group. They have sessions for every level of ADF awareness - from the beginner to the expert, and you can also learn about related technologies such as WebCenter and SOA Suite. Most of the sessions are run by users who share their real world experience with the technology. And me and other PMs will also be running a few sessions and hands-on labs there. Check out the list of sessions in the Fusion Middleware track. And don't miss the Sunday symposium too.

• Issue 55 - Skin Object Tokens, Optimized Control Panel, OWS Validation and Security, RAD

  April 2010 Welcome to Issue 55 of DNN Creative Magazine In this issue we focus on the new Skin Object token method introduced in DotNetNuke 5 for adding tokens into a DotNetNuke skin. A Skin Object Token is a web user control which covers skin elements such as the logo, menu, search, login links, date, copyright, languages, links, banners, privacy, terms of use, etc. Following this we demonstrate how to install and use two Advanced DotNetNuke Admin Control Panels which are available for free from Oliver Hine. These control panels provide an optimized version of the admin control panel to improve performance and page load times, as well as a ribbon bar control panel which adds additional features. Next, we continue the Open Web Studio tutorials, this month we demonstrate some very advanced techniques for building a car parts application in Open Web Studio. Throughout the tutorial we cover form input, validation, how to use dependant drop down lists, populating checkbox lists and introduce a new concept of data level security. Data level security allows you to control which data a user can access within a module. To finish, we have part five of the "How to Build a News Application with DotNetMushroom Rapid Application Developer (RAD)" article, where we demonstrate how to implement paging. This issue comes complete with 14 videos. Skinning: Skin Object Tokens for DotNetNuke 5 (8 videos - 64mins) Free Module: Advanced Optimized Control Panel by Oliver Hine (1 video - 11mins) Module Development Series: Form Validation, Dependant Drop Downs and Data Level Security in OWS (5 videos - 44mins) How to Implement Paging with DotNetMushroom RAD View issue 55 to download all of the videos in one zip file DNN Creative Magazine for DotNetNuke Web Designers Covering DotNetNuke module video reviews, video tutorials, mp3 interviews, resources and web design tips for working with DotNetNuke.

• Upgrading Visual Studio 2010

  - by Martin Hinshelwood

  I have been running Visual Studio 2010 as my main development studio on my development computer since the RC was released. I need to upgrade that to the RTM, but first I need to remove it. Microsoft have done a lot of work to make this easy, and it works. Its as easy as uninstalling from the control panel. I have had may previous versions of Visual Studio 2010 on this same computer with no need to rebuild to remove all the bits. Figure: Run the uninstall from the control panel to remove Visual Studio 2010 RC Figure: The uninstall removes everything for you.  Figure: A green tick means the everything went OK. If you get a red cross, try installing the RTM anyway and it should warn you with what was not uninstalled properly and you can remove it manually.   Once you have VS2010 RC uninstalled installing should be a breeze. The install for 2010 is much faster than 2008. Which could take all day, and then some on slower computers. This takes around 20 minutes even on my small laptop. I always do a full install as although I have to do c# I sometimes get to use a proper programming language VB.NET. Seriously, there is nothing worse than trying to open a project and the other developer has used something you don't have. Its not their fault. Its yours! Save yourself the angst and install Fully, its only 5.9GB. Figure: I always select all of the options.   Now go forth and develop! Preferably in VB.NET…   Technorati Tags: Visual Studio,VS2010,VS 2010

• Is there any reason not to go directly from client-side Javascript to a database?

  - by Chris Smith

  So, let's say I'm going to build a Stack Exchange clone and I decide to use something like CouchDB as my backend store. If I use their built-in authentication and database-level authorization, is there any reason not to allow the client-side Javascript to write directly to the publicly available CouchDB server? Since this is basically a CRUD application and the business logic consists of "Only the author can edit their post" I don't see much of a need to have a layer between the client-side stuff and the database. I would simply use validation on the CouchDB side to make sure someone isn't putting in garbage data and make sure that permissions are set properly so that users can only read their own _user data. The rendering would be done client-side by something like AngularJS. In essence you could just have a CouchDB server and a bunch of "static" pages and you're good to go. You wouldn't need any kind of server-side processing, just something that could serve up the HTML pages. Opening my database up to the world seems wrong, but in this scenario I can't think of why as long as permissions are set properly. It goes against my instinct as a web developer, but I can't think of a good reason. So, why is this a bad idea? EDIT: Looks like there is a similar discussion here: Writing Web "server less" applications EDIT: Awesome discussion so far, and I appreciate everyone's feedback! I feel like I should add a few generic assumptions instead of calling out CouchDB and AngularJS specifically. So let's assume that: The database can authenticate users directly from its hidden store All database communication would happen over SSL Data validation can (but maybe shouldn't?) be handled by the database The only authorization we care about other than admin functions is someone only being allowed to edit their own post We're perfectly fine with everyone being able to read all data (EXCEPT user records which may contain password hashes) Administrative functions would be restricted by database authorization No one can add themselves to an administrator role The database is relatively easy to scale There is little to no true business logic; this is a basic CRUD app

• Generic Repository with SQLite and SQL Compact Databases

  - by Andrew Petersen

  I am creating a project that has a mobile app (Xamarin.Android) using a SQLite database and a WPF application (Code First Entity Framework 5) using a SQL Compact database. This project will even eventually have a SQL Server database as well. Because of this I am trying to create a generic repository, so that I can pass in the correct context depending on which application is making the request. The issue I ran into is my DataContext for the SQL Compact database inherits from DbContext and the SQLite database inherits from SQLiteConnection. What is the best way to make this generic, so that it doesn't matter what kind of database is on the back end? This is what I have tried so far on the SQL Compact side: public interface IRepository<TEntity> { TEntity Add(TEntity entity); } public class Repository<TEntity, TContext> : IRepository<TEntity>, IDisposable where TEntity : class where TContext : DbContext { private readonly TContext _context; public Repository(DbContext dbContext) { _context = dbContext as TContext; } public virtual TEntity Add(TEntity entity) { return _context.Set<TEntity>().Add(entity); } } And on the SQLite side: public class ElverDatabase : SQLiteConnection { static readonly object Locker = new object(); public ElverDatabase(string path) : base(path) { CreateTable<Ticket>(); } public int Add<T>(T item) where T : IBusinessEntity { lock (Locker) { return Insert(item); } } }

• Add a Real-Time Earth Wallpaper App to Ubuntu with xplanetFX

  - by Asian Angel

  Are you tired of the same old wallpaper on your Ubuntu desktop? Now you can go from blah to literally spacious, real-time styled views of Earth with the xplanetFX Wallpaper App for Linux. You can conveniently access the “file type” downloads, screenshots, and jump-to links all on the front page. For our example we downloaded the .deb setup file on our system. The setup file will need to download three additional files to complete the setup process. After those are downloaded all dependencies will have been met and you can complete the installation process. Once that is done you can find xplanetFX by going to the Accessories Section of your Ubuntu Menu. This is what the main control window looks like when you start xplanetFX for the first time. You should take a few moments to look through the various tabs and tweak the settings for items like location, screen resolution, timing, auto-start, etc. When you are done click on Execute and within a few moments your desktop will have a fresh new look! Note: It took ~30 seconds for the display to activate on our system. Have fun with xplanetFX! xplanetFX Homepage [via OMG!

• What is the evidence that an API has exceeded its orthogonality in the context of types?

  - by hawkeye

  Wikipedia defines software orthogonality as: orthogonality in a programming language means that a relatively small set of primitive constructs can be combined in a relatively small number of ways to build the control and data structures of the language. The term is most-frequently used regarding assembly instruction sets, as orthogonal instruction set. Jason Coffin has defined software orthogonality as Highly cohesive components that are loosely coupled to each other produce an orthogonal system. C.Ross has defined software orthogonality as: the property that means "Changing A does not change B". An example of an orthogonal system would be a radio, where changing the station does not change the volume and vice-versa. Now there is a hypothesis published in the the ACM Queue by Tim Bray - that some have called the Bánffy Bray Type System Criteria - which he summarises as: Static typings attractiveness is a direct function (and dynamic typings an inverse function) of API surface size. Dynamic typings attractiveness is a direct function (and static typings an inverse function) of unit testing workability. Now Stuart Halloway has reformulated Banfy Bray as: the more your APIs exceed orthogonality, the better you will like static typing My question is: What is the evidence that an API has exceeded its orthogonality in the context of types? Clarification Tim Bray introduces the idea of orthogonality and APIs. Where you have one API and it is mainly dealing with Strings (ie a web server serving requests and responses), then a uni-typed language (python, ruby) is 'aligned' to that API - because the the type system of these languages isn't sophisticated, but it doesn't matter since you're dealing with Strings anyway. He then moves on to Android programming, which has a whole bunch of sensor APIs, which are all 'different' to the web server API that he was working on previously. Because you're not just dealing with Strings, but with different types, the API is non-orthogonal. Tim's point is that there is a empirical relationship between your 'liking' of types and the API you're programming against. (ie a subjective point is actually objective depending on your context).

• SQL SERVER – Copy Database – SQL in Sixty Seconds #067

  - by Pinal Dave

  There are multiple reasons why a user may want to make a copy of the database. Sometimes a user wants to copy the database to the same server and sometime wants to copy the database on a different server. The important point is that DBA and Developer may want copies of their database for various purposes. I copy my database for backup purpose. However, when we hear coping database – the very first thought which comes to our mind is – Backup and Restore or Attach and Detach. Both of these processes have their own advantage and disadvantages. The matter of the fact, those methods is much efficient and recommended methods. However, if you just want to copy your database as it is and do not want to go for advanced feature. You can just use the copy feature of the SQL Server. Here are the settings, which you can use to copy the database. SQL in Sixty Seconds Video I have attempted to explain the same subject in simple words over in following video. Action Item Here are the blog posts I have previously written on the subject of SA password.

• Open source clone for Starcraft

  - by sinekonata

  Two questions about a SC:Broodwar clone. Is there one yet? How likely is legal pursuit? Since almost all games I usually play now have an FOS alternative from alpha to way polished, I was wondering why can't I find one for SC, one of the biggest titans of the gaming community? So my first question is, is there a game that was made with the intention to emulate SC? Is it that I didn't look well enough? Could it really be that no one tackled what seems like a small effort compared to the creation of a game engine like Spring or games like Rigs of Rod or Minetest? And since SC is not being maintained at all shouldn't the incentive to see a bug free modable balanced version huge? What am I not getting here? In the event that there is none, is it a legal problem? Could it be that people expect Blizzard to release sources themselves? Or that developers don't see the point in having SC mechanics without the patented lore and aesthetics? And the trickier question, if I were to make SC an open source game, a total clone of it for the purposes of maintenance, modability, etc. Would Blizzard really sue a team of developer fans that just do them a favour knowing they don't lose any money from Korea broadcasts? Or would they do it not to set precedents. So thanks for reading all that, hope I'm not the only one to think it's weird that no one talks about it. See you.

• Should we be able to deploy a single package to the SSIS Catalog?

  - by jamiet

  My buddy Sutha Thiru sent me an email recently asking about my opinion on a particular nuance of the project deployment model in SQL Server Integration Services (SSIS) 2012 and I’d like to share my response as I think it warrants a wider discussion. Sutha asked: Jamie What is your take on this? http://www.mattmasson.com/index.php/2012/07/can-i-deploy-a-single-ssis-package-from-my-project-to-the-ssis-catalog/ Overnight I was talking to Matt who confirmed that they got no plans to change the deployment model. For example if we have following scenrio how do we do deploy? Sprint 1 Pkg1, 2 & 3 has been developed and deployed to UAT. Once signed off its been deployed to Live. Sprint 2 Pkg 4 & 5 been developed. During this time users raised a bug on Pkg2. We want to make the change to Pkg2 and deploy that to UAT and eventually to LIVE without releasing Pkg 4 &5. How do we do it? Matt pointed me to his blog entry which I have seen before . http://www.mattmasson.com/index.php/2012/02/thoughts-on-branching-strategies-for-ssis-projects/ Thanks Sutha My response: Personally, even though I've experienced the exact problem you just outlined, I agree with the current approach. I steadfastly believe that there should not be a way for an unscrupulous developer to slide in a new version of a package under the covers. Deploying .ispac files brings a degree of rigour to your operational processes. Yes, that means that we as SSIS developers are going to have to get better at using source control and branching properly but that is no bad thing in my opinion. Claiming to be proper "developers" is a bit of a cheap claim if we don't even do the fundamentals correctly. I would be interested in the thoughts of others who have used the project deployment model. Do you agree with my point of view? @Jamiet
