• Should I, and how do I incorporate microdata into my asp.net website with 47 pages?

  - by Jason Weber

  I have an asp.net (vb) with 47 pages. The problem is that it's in 10 different languages, although 98% just use English. I have 5 master pages. I've read Google Webmaster Tools, but I'm still confounded. I'm reading about how microdata is the way to go. Does this mean I should put itemtype and itemprop span and div tags in my master pages, or should I do all of my 47 pages (.resx resource files) separately? The main key phrase I want throughout search results is "machine vision". For instance, the first couple sentences on my "about.aspx" page are: <span itemprop="name">USS Vision Inc.</span> (USS) is a privately-owned company with headquarters in <span itemprop="locality">Detroit, Michigan, USA</span>. We design, engineer, produce, and integrate special machine vision error-proofing products and <a href="http://www.ussvision.com/services/" target="_self" itemprop="url">services</a> that create lean factories by improving the quality of manufactured products, and by significantly reducing manufacturing costs through advanced automation. Am I doing this right, or how would I do this if I'm not? Should I use the itemprop="url" or other rich snippets for every link in my website? I mean, do I need to add an itemprop to just about everything, or can I just alter my master pages? Any guidance in this regard to help improve my SEO and SERPS would be greatly appreciated!

• VS2012 Coded UI Test closes browser by default

  - by Tarun Arora

  *** Thanks to Steve St. Jean for asking this question and Shubhra Maji for answering this question on the ALM champs list *** 01 – Introduction The default behaviour of coded UI tests running in an Internet Explorer browser has changed between MTM 2010 and MTM 2012. When running a Coded UI test recorded in MTM 2012 or VS 2012 at the end of the test execution the instance of the browser is closed by default. 02 – Description Let’s take an example. As you can see the CloseDinnerNowWeb() method is commented out.  In VS 2010, upon running this test the browser would be left open after the test execution completes. In VS 2012 RTM the behaviour has changed. At the end of the test run, the IE window is closed even though there is no command from the test to do so. In the example below when the test runs, it opens 2 IE windows to the website. When the test run completes both the windows are closed, even though there is no command in the test to close the window. 03 – How to change the CUIT behaviour not to close the IE window after test execution? This change to this functionality in VS 2012 is by design. It is however possible to rollback the behaviour to how it originally was in VS 2010 i.e. the IE window will not close after the test execution unless otherwise commanded by the test to do so. To go back to the original functionality, set BrowserWindow.CloseOnPlaybackCleanup = false More details on the CloseOnPlaybackCleanup property can be found here http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.testtools.uitesting.applicationundertest.closeonplaybackcleanup.aspx  HTH

• What technical details should a programmer of a web application consider before making the site public?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application consider before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• Get to No as fast as possible

  - by Tim Hibbard

  There is a sales technique where the strategy is to get the customer to say “No deal” as soon as possible.  The idea being that by establishing terms that your customer is not comfortable with with, the sooner you can figure out what they will be willing to agree to.  The same principal can be applied to code design.  Instead of nested if…then statements, a code block should quickly eliminate the cases it is not equipped to handle and just focus on what it is meant to handle. This is code that will quickly become maintainable as requirements change: private void SaveClient(Client c) { if (c != null) { if (c.BirthDate != DateTime.MinValue) { foreach (Sale s in c.Sales) { if (s.IsProcessed) { SaveSaleToDatabase(s); } } SaveClientToDatabase(c); } } }   If an additional requirement comes along that requires the Client to have Manager approval or for a Sale to be under $20K, this code will get messy and unreadable. A better way to meet the same requirements would be: private void SaveClient(Client c) { if (c == null) { return; } if (c.BirthDate == DateTime.MinValue) { return; }   foreach (Sale s in c.Save) { if (!s.IsProcessed) { continue; } SaveSaleToDatabase(s); } SaveClientToDatabase(c); } This technique moves on quickly when it finds something it doesn’t like.  This makes it much easier to add a Manager approval constraint.  We would just insert the new requirement before the action takes place.

• Is there a typical career path to learn game development "on the job"?

  - by mac

  The extended version of the question is: what is the typical career paths that a developer without specific experience in game development should take if he/she wishes to work in the game development industry? In other words, what are the positions such a programmer might aspire to get hired for, in the game industry? I am asking because it seems to me that - even without direct experience with 3D modelling, physics engines, shaders, etc... - for as much complex as these topics might be - they are still "just" top layers one can learn "on the job" if he/she has already good programming skills and experience in software design (for example during peer-programming sessions). I have no knowledge whatsoever of the game industry, so maybe I am being naïve here, but for all the other programming jobs I previously took, I learnt most of the specificities while working on concrete projects... so I wonder if there is a chance to do the same with game development. Thanks for your time and advice! :) PS: I don't know if this is important or not for answering the question, but scripting languages are the languages I am more proficient in. /mac

• Question regarding Readability vs Processing Time

  - by Jordy

  I am creating a flowchart for a program with multiple sequential steps. Every step should be performed if the previous step is succesful. I use a c-based programming language so the lay-out would be something like this: METHOD 1: if(step_one_succeeded()) { if(step_two_succeeded()) { if(step_three_succeeded()) { //etc. etc. } } } If my program would have 15+ steps, the resulting code would be terribly unfriendly to read. So I changed my design and implemented a global errorcode that I keep passing by reference, make everything more readable. The resulting code would be something like this: METHOD 2: int _no_error = 0; step_one(_no_error); if(_no_error == 0) step_two(_no_error); if(_no_error == 0) step_three(_no_error); if(_no_error == 0) step_two(_no_error); The cyclomatic complexibility stays the same. Now let's say there are N number of steps. And let's assume that checking a condition is 1 clock long and performing a step doesn't take up time. The processing speed of Method1 can be anywhere between 1 and N. The processing speed of Method2 however is always equal to N-1. So Method1 will be faster most of the time. Which brings me to my question, is it bad practice to sacrifice time in order to make the code more readable? And why (not)?

• I can't program because the code I am using uses old coding styles. Is this normal to programmers? [closed]

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: Does not have comments Does not have functions (50, 100, 200, 300 or more lines executed in sequence) Uses a lot of if statements with a lot of paths Has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) Uses an old language (Visual FoxPro 8 from 2002), but there are new releases from 2007. I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way? EDIT: All the answers are very good. For my (un)hope, appears that there are a lot of this kind of code bases around the world. A point mentioned to all answers is refactor the code. Yeah, I really like to do it. In my personal project, I always do this, but... I can't refactor the code. Programmers are only allowed to change the files in the task that they are designed for. Every change in old code must be keep commented in the code (even with Subversion as version control), plus meta informations (date, programmer, task) related to that change (this became a mess, there are code with 3 used lines and 50 old lines commented). I'm thinking that is not only a code problem, but a management of software development problem.

• Geekswithblogs.net | Screen Resolutions of our Readers

  - by Jeff Julian

  Yesterday I talked about the Browsers we see being used by our readers driven off of our Google Analytics traffic and today I want to share with you the Screen Resolutions we see.  As a web developer most of my life, it is hard to decide how large you should build your application because typically you have a couple huge high resolution monitors on your desk, but you typical end user is thought to have 1024x768.  With HTML5/CSS3 out, it is a little better coming up with a design that will scale to all resolutions, but it is still nice to know the numbers when it comes to how much real estate do I have on my clients. If you look at these numbers for Geekswithblogs.net, we have a lot of high resolution monitors from users that visit the site.  After a little more investigation of the number you will notice we do not have as much height available as we do width.  If the primary goal of a site is to deliver as much data in the viewable area without scrolling, this becomes a challenge when most of our pages have long pieces of formatted data.  So our challenge is to build skins that use up more of the sides of the content toward the top on larger resolution browsers and then entice the reader to scroll to get the goodies embedded in the content of the posts.  Going to be an interesting battle for sure, but we really need more skin offerings on the site.

• Entity system in Lua, communication with C++ and level editor. Need advice.

  - by Notbad

  Hi!, I know this is a really difficult subject. I have been reading a lot this days about Entity systems, etc... And now I'm ready to ask some questions (if you don't mind answering them) because I'm really messed. First of all, I have a 2D basic editor written in Qt, and I'm in the process of adding entitiy edition. I want the editor to be able to receive RTTI information from entities to change properties, create some logic being able to link published events to published actions (Ex:A level activate event throws a door open action), etc... Because all of this I guess my entity system should be written in scripting, in my case Lua. In the other hand I want to use a component based design for my entities, and here starts my questions: 1) Should I define my componentes en C++? If I do this en C++ won't I loose all the RTTI information I want for my editor?. In the other hand, I use box2d for physics, if I define all my components in script won't it be a lot of work to expose third party libs to lua? 2) Where should I place the messa system for my game engine? Lua? C++?. I'm tempted to just have C++ object to behave as servers, offering services to lua business logic. Things like physics system, rendering system, input system, World class, etc... And for all the other things, lua. Creation/Composition of entities based on components, game logic, etc... Could anyone give any insight on how to accomplish this? And what aproach is better?. Thanks in advance, HexDump.

• How the OS Makes the Database Scream

  - by rickramsey

  source Few things are as satisfying as a screaming burnout. When Oracle Database engineers team up with Solaris engineers, they do a lot of them. Here are a few of the reasons why. Article: How the OS Makes the Database Fast - Oracle Solaris For applications that rely on Oracle Database, a high-performance operating system translates into faster transactions, better scalability to support more users, and the ability to support larger capacity databases. When deployed in virtualized environments, multiple Oracle Database servers can be consolidated on the same physical server. Ginny Henningsen describes what Oracle Solaris does to make the Oracle database run faster. Interview: Why Is The OS Still Relevant? In a world of increasing virtualization and growing interest in cloud services, why is the OS still relevant? Michael Palmeter, senior director of Oracle Solaris, explains why it's not only relevant, but essential for data centers that care about performance. Interview: An Engineer's Perspective: Why the OS Is Still Relevant Sysadmins are handling hundreds or perhaps thousands of VM's. What is it about Solaris that makes it such a good platform for managing those VM's? Liane Praza, senior engineer in the Solaris core engineering group provides an engineer's perspective. Interview in the Lab: How to Get the Performance Promised by Oracle's T5 SPARC Chips If you want your applications to run on the new SPARC T5/M5 chips, how do you make sure they use all that new performance? Don Kretsch, Senior Director of Engineering, explains. Interview: Why Oracle Database Engineering Uses Oracle Solaris Studio The design priorities for Oracle Solaris Studio are performance, observability, and productivity. Why this is good for ISV's and developers, and why it's so important to the Oracle database engineering team.

• PHP Image gallery that integrates well into custom CMS

  - by Thorarin

  I've been trying to find an image gallery that plays nice with our custom CMS. I've evaluated a number of them, but none of them seems to have the feature list that I would like: Run on LAMP environment Free software or low license costs (the website belongs to a non-profit organisation) Multi-user support Multiple albums. We're posting concert pictures, and would like an album per event. Pluggable authentication system. I want to reuse the accounts we have for our CMS. Permissions can be done inside the gallery itself, but I want to have a single sign on solution in a maintainable manner, by writing my own plugin/add-on for the software. Upload support (multiple images at the same time) And preferrably also: Can be integrated into a PHP page layout without IFRAMEs Automatic resizing of uploaded images to a maximum size Ability for visitors to place comments This combination is proving hard to find, especially the authentication requirement. I don't want to mess around all over the place in the source code to make it use the existing authentication. A plugin would be ideal, but alternatively a well thought out software design that allows for maintainable surgical changes would be acceptable. Any suggestions on which software I should take a closer look into?

• Inexplicable low ranking [closed]

  - by Mick

  I have created two similar websites relating to monetary systems. So far, one appears to be loved by Google and the other hated. I'm struggling to work out why. The successful one is fullreservebanking.com. If you type in "full reserve banking" into Google, my site appears 2nd in the list behind Wikipedia. The unsuccessful one is fractionalreserves.com. If you type in "fractional reserve banking" into Google, it's nowhere to be seen. This is a mystery to me because both sites were created by me with the same design philosophy, both in pure html. Both are packed to the rafters with references to, and information about, their respective subjects. One issue I'm worried may be the cause is to do with the location of the sites. I got a web hosting package from hostmonster.com for fullreservebanking, but fractionalreserves is just an "add-on" which sits on a subdirectory of fullreservebanking. I wonder if Google somehow detects this and treats it as a less significant website?

• Google search question, front page not showing

  - by user5746

  I know this is probably a dumb question but I hope someone can give me some insight; I was ranked on Google first page of search results for "funny st patricks day shirts" but I was third from the bottom and not familiar enough with SEO, so I signed up for "Attracta" to rank higher. Big mistake. Since using Attracta, I've lost the first page and I'm now on the fourth page in that search. What I noticed is that Google is now just showing a sub-page or side page, (a link from my front page, to a page which has only a few designs in it) this is not where I would want customers to land first... but my front page is not showing in that search anymore. Obviously, the title of this side page is not geared toward that search result, so I know that's why I have the pr drop. Why is my front page not ranking over that page, though? Why is it apparently gone from that search, or so far back no one will ever find it? I need to know how to fix this quick if anyone has any advice at all for me. It's the busiest season for my website and the people who were stealing design ideas from me are all ranked higher than my site now. (I can prove this, lol) So, I'm very frustrated by that. I would be very grateful to have any advice at all as to what I can do to fix this. THANKS in advance for any advice you can offer. Catelyn

• How to plan/manage multi-platform (mobile) products?

  - by PhD

  Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

• How should I track approval workflow when users at every security level can create a request?

  - by Eric Belair

  I am writing a new application that allows users to enter requests. Once a request is entered, it must follow an approval workflow to be finally approved by a user the highest security level. So, let's say a user at Security Level 1 enters a request. This request must be approved by his superior - a user at Security Level 2. Once the Security Level 2 user approves it, it must be approved by a user at Security Level 3. Once the Security Level 3 user approves it, it is considered fully approved. However, users at any of the three Security Levels can enter requests. So, if a Security Level 3 user enters a request, it is automatically considered "fully approved". And, if a Security Level 2 user enters a request, it must only be approved by a Security Level 3 user. I'm currently storing each approval status in a Database Log Table, like so: STATUS_ID (PK) REQUEST_ID STATUS STATUS_DATE -------------- ------------- ---------------- ----------------------- 1 1 USER_SUBMIT 2012-09-01 00:00:00.000 2 1 APPROVED_LEVEL2 2012-09-01 01:00:00.000 3 1 APPROVED_LEVEL3 2012-09-01 02:00:00.000 4 2 USER_SUBMIT 2012-09-01 02:30:00.000 5 2 APPROVED_LEVEL2 2012-09-01 02:45:00.000 My question is, which is a better design: Record all three statuses for every request ...or... Record only the statuses needed according to the Security Level of the user submitting the request In Case 2, the data might look like this for two requests - one submitted by Security Level 2 User and another submitted by Security Level 3 user: STATUS_ID (PK) REQUEST_ID STATUS STATUS_DATE -------------- ------------- ---------------- ----------------------- 1 3 APPROVED_LEVEL2 2012-09-01 01:00:00.000 2 3 APPROVED_LEVEL3 2012-09-01 02:00:00.000 3 4 APPROVED_LEVEL3 2012-09-01 02:00:00.000

• Is it possible to generate Events and Hooks in Lua for any game without built-in support?

  - by pr0tocol

  Does a game have to have built-in functions to accept and run lua scripts, or can I design Events and Hooks using Lua on any game I please, akin to the days where C code could be used to hook into the WinAPI using dlls? The reason I ask is, I am trying to create a background application that will perform events and hooks on a particular game that does not currently support lua in-game. Brief examples: Events: - An action executed by the PLAYER is detected. For instance, hitting the Q key will normally make my character use an ability, but with my Lua script running in the background, will cause a sound to play on my computer (or something). Hooks: - An action within the GAME is detected. For instance, the game spawns an enemy every minute. When an enemy spawns, the script will detect this and perform an action, for instance playing a sound locally on the computer. I would like to do both, but I know for games like Garry's Mod, the game already has built-in support for running lua scripts. Is there a way to do either events OR hooks using lua similarly to how C/C++ can connect to a game using WinAPI dlls?

• How should I structure moving from overworld to menu system / combat?

  - by persepolis

  I'm making a text-based "Arena" game where the player is the owner of 5 creatures that battle other teams for loot, experience and glory. The game is very simple, using Python and a curses emulator. I have a static ASCII map of an "overworld" of sorts. My character, represented by a glyph, can move about this static map. There are locations all over the map that the character can visit, that break down into two types: 1) Towns, which are a series of menus that will allow the player to buy equipment for his team, hire new recruits or do other things. 2) Arenas, where the player's team will have a "battle" interface with actions he can perform, messages about the fight, etc. Maybe later, an ASCII representation of the fight but for now, just screens of information with action prompts. My main problem is what kind of design or structure I should use to implement this? Right now, the game goes through a master loop which waits for keyboard input and then moves the player about the screen. My current thinking is this: 1) Upon keyboard input, the Player coordinates are checked against a list of Location objects and if the Player coords match the Location coords then... 2) ??? I'm not sure if I should then call a seperate function to initiate a "menu" or "combat" mode. Or should I create some kind of new GameMode object that contains a method itself for drawing the screen, printing the necessary info? How do I pass my player's team data into this object? My main concern is passing around the program flow into all these objects. Should I be calling straight functions for different parts of my game, and objects to represent "things" within my game? I was reading about the MVC pattern and how this kind of problem might benefit - decouple the GUI from the game logic and user input but I have no idea how this applies to my game.

• SEO and external sites that serve responsive images (like Re-SRC)

  - by Baumr

  Re-SRC is a tool that allows you to automatically serve responsive images for your website from their cloud servers. It delivers a new image file each time the browser window (viewport) is resized. To use it in your HTML when linking to an image, you would do the following: <img src="http://app.resrc.it//www.your-domain.com/img/img001.jpg"/> Some more background for SEO considerations: As an example, looking at their demo page's code, the src of the Arc de Triomphe photo — when the browser window is resized to be at a tablet-width — shows this particular file at it's widest. It is found under the following URL: http://app4-uk.resrc.it/s=w560,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg If the viewport is increased to desktop-width, then a smaller image is served in line with the design; see this URL: http://app4-uk.resrc.it/s=w320,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg If I change the viewport to be about half-way between those two, then the image's URL is: http://app4-uk.resrc.it/s=w240,pd1/ro=h//www.resrc.it/img/demo/demo-image-1.jpg In other words, I found that there is a separate file for every 10-pixel increment of the image width. Very cool for saving bandwidth on mobile devices and service responsive/retina images on others, but... Here are two problems I see for SEO: The img on your site, part of your semantic markup, will not be hosted on your site at all, or even a server you control. Any links to these images will pass on "link juice" to Re-SRC's site instead. You are serving a vast array of different image files to different people — some may link to one, others to another size. Then there's the question of what different search engine crawlers will see. Also: There seems to be no fallback option if their servers are down. Do you see any other concerns? Or, perhaps, do you not see those as concerns?

• Start a new project. Where is the inspiration ?

  - by Kakawait

  The question may seem strange at first glance ... And I may be alone in this situation. But currently I want to improve my skill through learning new framework. however, do a simple "HelloWorld" application does not satisfy me. I think a practical project is required to apprehend the basics of a framework. I know there is many scholar-like project like design a library manager or CMS. But I have recently planned to learn ~3 differents frameworks and I can't find any motivations through "unexciting" project. In the end I have not started any framework ... I'm aware of I do not develop the project of the year ... I'm just looking for something a bit exciting. I do not expect any project subject, anyway stimulation provided by a project is something subjective. But I want to know your inspiration ! (or method to learn framework ^^) I'm talking about web-dev framework but I'm open to any kind information ! Kind regards.

• Storing Tiled Level Data in J2ME game

  - by Alex

  I'm developing a J2ME game which uses tiled backgrounds for the levels. My question is how do I store this tile information in my game. At the moment it is stored as an array; with each number representing a different tile from the tile-sheet. This works well enough, however I don't like the fact that it is 'hard-coded' into the game because (at least in my opinion) it is harder to edit the levels, or design new ones. I was also thinking that it would be difficult if you wanted to add a 'level pack', I'm not sure on how this would be achieved though; it's not something I was planning on doing, I'm just curious. I was wondering if there was a way I could store level data in some external file and then load this in to the game. The problem is I don't know what the limitations are for J2ME regarding file I/O, can it read in any file like Java? I am aware of the RMS, but from my experience I don't think this would work (unless I am mistaken). Also, would loading the data in this way be too big a performance hit? Or is there another way I can achieve what I am trying to do. As I said, the way I have it at the moment works fine, and if this is the only viable option then it will suffice.

• What are the most necessary non-language specific things a programmer needs to know?

  - by Josh

  I've been thinking about this a lot lately. Right now I work at a little web company, am almost done with school, and have written an iPhone app, but I'm not sure what else I need to focus my learning energies on. I've decided I want to do software programming, so I've been actively reading everything I can get my hands on that deals with Objective-C / C++ (Cocoa, OpenGL, etc). But those are not the things I'm talking about. I know I need to "master" a language or two. What I'm talking about are the other "things". Things such as learning and using source control, design patterns, etc. What thing (or things, just one per response), would you say I should concurrently be focusing on? You can consider in your answer that I'm wanting to do the aforementioned career path, but you don't have to. I just want a nice list of things to research, and actually use in my career. Also, can someone help me with tagging this? I'm not sure what exactly would be a good tag for such a question.

• Costs/profit of/when starting an indie company

  - by Jack

  In short, I want to start a game company. I do not have much coding experience (just basic understanding and ability to write basic programs), any graphics design experience, any audio mixing experience, or whatever else technical. However, I do have a lot of ideas, great analytical skills and a very logical approach to life. I do not have any friends who are even remotely technical (or creative in regards to games for that matter). So now that we've cleared that up, my question is this: how much, minimally, would it cost me to start such a company? I know that a game could be developed in under half a year, which means it would have to operate for half a year prior, and that's assuming that the people working on the first project do their jobs good, don't leave game breaking bugs, a bunch of minor bugs, etc.. So how much would it cost me, and what would be the likely profit in half a year? I'm looking at minimal costs here, as to do it, I would have to sell my current apartment and buy a new, smaller one, pay taxes, and likely move to US/CA/UK to be closer to technologically advanced people (and be able to speak the language of course). EDIT: I'm looking at a small project for starters, not a huge AAA title.

• How to cut the line between quality and time?

  - by m3th0dman

  On one hand, I have been taught by various software engineering books ([1] as example) that my job as a programmer is to make the best possible software: great design, flexibility, to be easily maintained etc. One the other hand although I realize that I actually write software for money and not for entertainment, although is very nice to write good code and plan ahead and refactor after writing and ... I wonder if it is always best for the business (after all we should be responsible). Is the business always benefiting from a best code? Maybe I'm over-engineering something, and it's not always useful? So how should I know when to stop in the process to achieving the best possible code? I am sure that experience is something that makes a difference here, but I believe this cannot be the only answer. [1] Uncle Bob's in Clean Code says at page 6 about the fact that: They [managers] may defend the schedule and requirements with passion; but that’s their job. It’s your job to defend the code with equal passion.

• Have there been attempts to make object containers that search for valid programs by auto wiring compatible components?

  - by Aaron Anodide

  I hope this post isn't too "Fringe" - I'm sure someone will just kill it if it is :) Three things made me want to reach out about this now: Decoupling is so in the forefront of design. TDD inspires the idea that it doesn't matter how a program comes to exist as long as it works. Seeing how often the adapter pattern is applied to achieve (1). I'm almost sure this has been tried from a memory of reading about it around the year 2000 or so. If I had to guess, it was maybe about and earlier version of the Java Spring framework. At this time we were not so far from days when the belief was that computer programs could exhibit useful emergent behavior. I think the article said it didn't work, but it didn't say it was impossible. I wonder if since then it has been deemed impossible or simply an illusion due to a false assumption of similarity between a brain and a CPU. I know this illusion existed because I had an internship in 1996 where I programmed neural nets that were supposedly going to exhibit "brain damage". STILL, after all that, I'm sitting around this morning and not able to shake the idea that it should be possible to have a method of programming to allow autonomous components to find each other, attempt to collaborate and their outputs evaluated against a set desired results.

• Tech Article: Tired of Null Pointer Exceptions? Use Java SE 8's Optional!

  - by Tori Wieldt

  A wise man once said you are not a real Java programmer until you've dealt with a null pointer exception. The null reference is the source of many problems because it is often used to denote the absence of a value. Java SE 8 introduces a new class called java.util.Optional that can alleviate some of these problems. In the tech article "Tired of Null Pointer Exceptions? Use Java SE 8's Optional!" Java expert Raoul-Gabriel Urma shows you how to make your code more readable and protect it against null pointer exceptions. Urma explains "The purpose of Optional is not to replace every single null reference in your codebase but rather to help design better APIs in which—just by reading the signature of a method—users can tell whether to expect an optional value. In addition, Optional forces you to actively unwrap an Optional to deal with the absence of a value; as a result, you protect your code against unintended null pointer exceptions." Learn how to go from writing painful nested null checks to writing declarative code that is composable, readable, and better protected from null pointer exceptions.
