• Office arangement - comfort vs. teamwork?

  - by finrod

  Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.

• Amazon CloudFormations and Oracle Virtual Assembly Builder

  - by llaszews

  Yesterday I blogged about AWS AMIs and Oracle VM templates. These are great mechanisms to stand up an initial cloud environment. However, they don't provide the capability to manage, provision and update an environment once it is up and running. This is where AWS Cloud Formations and Oracle Virtual Assembly Builder comes into play. In a way, these tools/frameworks pick up where AMIs and VM templates leave off. Once again, there a similar offers from AWS and Oracle that compliant and also overlap with each other. Let's start by looking at the definitions: AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion. AWS CloudFormations Oracle Virtual Assembly Builder - Oracle Virtual Assembly Builder makes it possible for administrators to quickly configure and provision entire multi-tier enterprise applications onto virtualized and cloud environments. Oracle VM Builder As with the discussion around should you use AMI or VM Templates, there are pros and cons to each: 1. CloudFormation is JSON, Assembly Builder is GUI and CLI 2. VM Templates can be used in any private or public cloud environment. Of course, CloudFormations is tied to AWS public cloud

• Should I modify an entity with many parameters or with the entity itself?

  - by Saeed Neamati

  We have a SOA-based system. The service methods are like: UpdateEntity(Entity entity) For small entities, it's all fine. However, when entities get bigger and bigger, to update one property we should follow this pattern in UI: Get parameters from UI (user) Create an instance of the Entity, using those parameters Get the entity from service Write code to fill the unchanged properties Give the result entity to the service Another option that I've experienced in previous experiences is to create semantic update methods for each update scenario. In other words instead of having one global all-encompasing update method, we had many ad-hoc parametric methods. For example, for the User entity, instead of having UpdateUser (User user) method, we had these methods: ChangeUserPassword(int userId, string newPassword) AddEmailToUserAccount(int userId, string email) ChangeProfilePicture(int userId, Image image) ... Now, I don't know which method is truly better, and for each approach, we encounter problems. I mean, I'm going to design the infrastructure for a new system, and I don't have enough reasons to pick any of these approaches. I couldn't find good resources on the Internet, because of the lack of keywords I could provide. What approach is better? What pitfalls each has? What benefits can we get from each one?

• What is the basic loadout for an open source web developer?

  - by DeveloperDon

  Thus far, I have mainly been an embedded developer, but I am interested in having the flexibility to do mobile and web development as well. I think my tools should include the following, but probably a lot more. LAMP stack. Java IDEs like Eclipse and IntelliJ. JS frameworks like Dojo, Node.JS, AngularJS, (is it better to mix or commit to one?). Cloud solutions like EC2 and Azure (again, ok to mix or better to commit to one?). Google APIs. Continuous integration server. Source control tools with Git for new work, SVN, CVS, +others for imports. FTP server. Unit test runners. Bug trackers. OOAD modeling tools or plug-ins? Graphic design tools? Hosting services. XML / JSON / other markup? Content management, SEO? I am also interested to know if there are tools where it might be better to mix, match, or support all available (maybe for source control) and others where the full focus should be on one (maybe Java vs. C# or Windows vs. Linux vs. MacOS). Perhaps some of these questions need context of whether the projects will be greenfield (just pick favorite) or maintenance (no choice, each project continues legacy, sometimes with a poor tools).

• How can I improve my isometric tile-picking algorithm?

  - by Cypher

  I've spent the last few days researching isometric tile-picking algorithms (converting screen-coordinates to tile-coordinates), and have obviously found a lot of the math beyond my grasp. I have come fairly close and what I have is workable, but I would like to improve on this algorithm as it's a little off and seems to pick down and to the right of the mouse pointer. I've uploaded a video to help visualize the current implementation: http://youtu.be/EqwWcq1zuaM My isometric rendering algorithm is based on what is found at this stackoverflow question's answer, with the exception that my x and y axis' are inverted (x increased down-right, while y increased up-right). Here is where I am converting from screen to tiles: // these next few lines convert the mouse pointer position from screen // coordinates to tile-grid coordinates. cameraOffset captures the current // mouse location and takes into consideration the camera's position on screen. System.Drawing.Point cameraOffset = new System.Drawing.Point( 0, 0 ); cameraOffset.X = mouseLocation.X + (int)camera.Left; cameraOffset.Y = ( mouseLocation.Y + (int)camera.Top ); // the camera-aware mouse coordinates are then further converted in an attempt // to select only the "tile" portion of the grid tiles, instead of the entire // rectangle. this algorithm gets close, but could use improvement. mouseTileLocation.X = ( cameraOffset.X + 2 * cameraOffset.Y ) / Global.TileWidth; mouseTileLocation.Y = -( ( 2 * cameraOffset.Y - cameraOffset.X ) / Global.TileWidth ); Things to make note of: mouseLocation is a System.Drawing.Point that represents the screen coordinates of the mouse pointer. cameraOffset is the screen position of the mouse pointer that includes the position of the game camera. mouseTileLocation is a System.Drawing.Point that is supposed to represent the tile coordinates of the mouse pointer. If you check out the above link to youtube, you'll notice that the picking algorithm is off a bit. How can I improve on this?

• Open Source Projects for Beginning Coders?

  - by MattDMo

  After working as a molecular biologist at the bench for many years, I lost my job last year and am thinking about a career change. I've been using open-source software and doing Linux system administration since the mid 90s, and have written/improved some small shell/Perl/PHP scripts, and am very comfortable building from source, but never progressed to creating non-trivial programs de novo. I want to move to actually learning real programming skills and contributing back to the community, with the possible eventual goal of getting into bioinformatics as a career in the future. I'm a stay-at-home dad now, so I have some time on my hands. I've done a lot of research on languages, and have settled on Python as my major focus for now. I'm set up on GitHub, but haven't forked anything yet. I've looked around OpenHatch some, but nothing really grabbed me. I've heard the advice to work on what you use/love, but that category is so broad that I'm having trouble finding any one thing to get started on. What are your suggestions for getting started? How do you pick a project that will welcome your (possibly amateurish) help? With a fairly limited skill set, how do you find a request that you can handle? What are common newbie mistakes to avoid? Any other advice?

• SEO - different data with same title and keywords

  - by Junaid Saeed

  here is my scenario i have a website where i redirect my users basing upon the device they were using, lets say a user is visiting from an iPad, i take him directly to the page of iPad wallpapers, the user selects iPad version & i take the user to the gallery of wallpapers where the user can select & download any wallpaper. Every wallpaper is the required resolution, i have my reasons for doing this, now the thing is there are diff. resolution. versions of an image appearing one 5 diff. sections of my website, each having their own view page Now there is only one record in db.table for the image, and basing on the my consistent naming convention of the images, i pick the required image. this means when 5 different pages are generated in 5 categorized sections of the website, due to a shared DB record, the keywords, the titles and every single detail of the 5 pages is same besides the resolution of the image, and the section specific details that the page has and yeah the pages also have different paths like wallpapers.com\ipad-1\cars\Ferrari-dino.html wallpapers.com\ipad-2\cars\Ferrari-dino.html wallpapers.com\ipad-3\cars\Ferrari-dino.html wallpapers.com\ipad-4\cars\Ferrari-dino.html wallpapers.com\ipad-5\cars\Ferrari-dino.html now this is my scenario, How do Search Engines see it and how do they rank it? Is it a Good or Normal or Bad SEO practice? If bad how dangerous it is for my sites SEO? i need your comments on my scenario.

• Upgrade went wrong, laptop essentially 'bricked'

  - by hexagonheat

  I have an old netbook I was trying to upgrade from 10.04 to 10.10. Ubuntu was in the process of upgrading when everything completely froze. I left it sit for an hour but it would not respond to anything. So I powered down the machine and it didn't have the necessary files to run Ubuntu. I went to the terminal and it told me to put in some command that I can not remember to 'rebuild' something. That takes me to now, when I turn on the laptop it comes up with a screen "GNU GRUB version 1.98+20100804-5ubuntu3.3" and has a bunch of options such as: 1. Ubuntu, with Linux 2.6.35-32-generic 2. Ubuntu, with Linux 2.6.35-32-generic (recover mode) etc. (there are like 15 of these with different numbers after 2.6.35 and the word 'generic'. It doesn't seem to matter what I pick, it will go to the "Ubuntu" loading screen with the colored dots but then every time it will freeze and I have to reboot to the same thing. I can't seem to get a terminal prompt anywhere either. Any ideas? I can't think of what to do :(

• Docker vs ESXi for Startup Projects - Deploying Code for Dev Testing

  - by JasonG

  Why hello there little programmer dude! I have a question for you and all of your experience and knowledge. I have an ESXi whitebox that I built which is an 8 dude that sits in the corner. I made a mistake recently and took the key that had ESXi, formatted it and used it for something else. No big deal because the last project I worked on had stalled out. I'm about to pick up another project and now I need to spin up a whole bunch of stuff for CI, qa + db, ticket tracker, wikis etc etc. I've been hearing a lot about Docker recently and as this is just a consumer grade machine, I'm wondering if it may make more sense for me to use Docker on OpenOS and then put everything there - bamboo or hudson, jira, confluence, postgress for the tools to use, then a qa env. I can't really seem to find any documents that directly compare traditional VM infrastructure vs docker solutions and I'm wondering if it is fair to compare. Is there any reason why CoreOS w/ containers would be a strictly worse solution? Or do you have any insight into why I may want to stick with ESXi? I've looked on multiple occasions and can't find a good reason not to. I'm not going to run a production env on the server so I don't need to have HA if updating security or OS for example where esxi would allow me to restart one vm at a time. I can just shut the thing down and bring it back up if I need a reboot no problem. So what's up with this container stuff? Is it a fair replacement for ESXi? I'm guessing the atlassian products would run much better and my ram would go a lot farther using docker. Probably the CPU would run much cooler too and my expensive HDD space would be better utilized.

• Learning good OOP design & unlearning some bad habits

  - by Nick

  I have been mostly a C programmer so far in my career with knowledge of C++. I rely on C++ mostly for the convenience STL provides and I hardly ever focus on good design practices. As I have started to look for a new job position, this bad habit of mine has come back to haunt me. During the interviews, I have been asked to design a problem (like chess, or some other scenario) using OOP and I doing really badly at that (I came to know this through feedback from one interview). I tried to google stuff and came up with so many opinions and related books that I don't know where to begin. I need a good through introduction to OOP design with which I can learn practical design, not just theory. Can you point me to any book which meets my requirements ? I prefer C++, but any other language is fine as long as I can pick-up good practices. Also, I know that books can only go so far. I would also appreciate any good practice project ideas that helped you learn and improve your OOP concepts. Thanks.

• Linux,Apache,NetBeans,PHP == Windows,IIS/Cassini,Visual Studio,ASP.Net

  - by Neil Smith

  I've worked out how to get my linux based Netbeans PHP development machine to behave much like what happens when you create a new ASP.Net project in Visual Studio. Firstly create multiple PHP project in Netbeans,say for example mysite1 and mysite2. Next edit the apache2/sites-enabled/000-default file and add two virtualhost sections as below <VirtualHost 127.0.1.1> ServerName mysite1.localhost DocumentRoot /var/www/mysite1/ </VirtualHost> <VirtualHost 127.0.2.1> ServerName mysite2.localhost DocumentRoot /var/www/mysite2/ </VirtualHost> For each site you add, pick a different ip address similar to the above where I use the third octet to increment, next edit the etc/hosts file and add the following two lines 127.0.1.1 mysite1.localhost 127.0.2.1 mysite2.localhost Then in Netbeans, go to File->Project Properties click on 'Run Configuration' and set 'Project Url' to http://mysite1.localhost for the first project and http://mysite2.localhost for the second project. That will give you a PHP development box which develops multiple PHP projects similar to how a Visual Studio Windows based box handles multiple ASP.Net sites. Hope this helps someone :)

• Dell Upgrade to 12.04 LTS No wifi, graphic card driver and bluetooth Problem?

  - by Mattlinux1

  (Dell inspiron m5040 Upgrade to 12.04 LTS from 11.10 wifi wont work and has two bluetooth icons?) Old title of post! No Wifi/Bluetooth Problem. "Both Fixed", see below comments for bluetooth fix and see bottom answer for wifi fix. My online upgrade of 12.04 LTS, was installed to my laptop the Dell inspiron m5040, when it was done i found that my wifi did not even get picked up anymore and i now have two bluetooth icons at the top?? So what i have been doing for now is at the boot screen. I hit the use previous linux version, this works fine but also has the two bluetooth at the top. Is very thankful for any answers for this fix, Thank You. Ok bluetooth problem solved by – fossfreedom answer by deleting the other bluetooth program running in software center. Now the other problem is Wifi: just have to restart system as it works in previous linux version boot opt, but on the first boot screen opt run ubuntu it will not pick up wifi drivers. Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4313-, BCM4321-,BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-basedhardware. And 3D-accelerated proprietary graphics driver for ATI cards. This driver is required to fully utilise the 3D potential of some ATI graphics cards, as well as provide 2D acceleration of newer cards. will not instill is there anyway for me to make a copy of the drivers via usb HDD and then put them on new upgraded version.

• How to avoid game objects accidentally deleting themselves in C++

  - by Tom Dalling

  Let's say my game has a monster that can kamikaze explode on the player. Let's pick a name for this monster at random: a Creeper. So, the Creeper class has a method that looks something like this: void Creeper::kamikaze() { EventSystem::postEvent(ENTITY_DEATH, this); Explosion* e = new Explosion; e->setLocation(this->location()); this->world->addEntity(e); } The events are not queued, they get dispatched immediately. This causes the Creeper object to get deleted somewhere inside the call to postEvent. Something like this: void World::handleEvent(int type, void* context) { if(type == ENTITY_DEATH){ Entity* ent = dynamic_cast<Entity*>(context); removeEntity(ent); delete ent; } } Because the Creeper object gets deleted while the kamikaze method is still running, it will crash when it tries to access this->location(). One solution is to queue the events into a buffer and dispatch them later. Is that the common solution in C++ games? It feels like a bit of a hack, but that might just be because of my experience with other languages with different memory management practices. In C++, is there a better general solution to this problem where an object accidentally deletes itself from inside one of its methods?

• Armchair CEO: Windows

  - by Scott Kuhl

  Originally posted on: http://geekswithblogs.net/scottkuhl/archive/2013/10/12/armchair-ceo-windows.aspxWelcome to part 3 of my Armchair CEO series where I prove just why I’m not running Microsoft.  In this insightful edition I’ll tell you how to make Windows, the golden flagship of Microsoft, a better product. Android Apps Windows Phone is not the only app store that needs a boost.  But unlike Windows Phone, there is a very easy way to get a lot more apps on your Windows PC: BlueStacks.  Right now BlueStacks has 3 things going against it: its UI integration is a desktop app hack, it does not work on RT, and no one know about it.  All three could be fixed if Microsoft bought the company or pulled off the same thing.  The store can be designed to give preference to Windows Store apps but it closes a lot of holes quickly. The Desktop Experience Windows should switch between desktop mode and tablet mode automatically.  Laptops without touch and desktops should work a lot more like Windows 7.  The PC should boot to desktop and Metro apps should run in windows, like MetroMix.  A tablet should boot to the Start Screen by default and pretty much work the same way it does now in 8.1.  Touch laptops should give the user an in your face option on first boot to pick the experience.  And finally, the experience can be changed automatically if the PC is docked or has external monitors hooked up. Death of the Desktop This might seem completely opposite to the last feature, but its not.  I should have no need to ever see the desktop from Start Screen mode.  Every settings needs to be available, an amazing port of the file explorer is needed, and Office Metro must be released.  Desktop apps should also be able to run in full screen mode like other Metro apps.

• can canonical links be used to make 'duplicate' pages unique?

  - by merk

  We have a website that allows users to list items for sale. Think ebay - except we don't actually deal with selling the item, we just list it for sale and provide a way to contact the seller. Anyhow, in several cases sellers maybe have multiple units of an item for sale. We don't have a quantity field, so they upload each item as a separate listing (and using a quantity field is not an option). So we have a lot of pages which basically have the exact same info and only the item # might be different. The SEO guy we've started using has said we should put a canonical link on each page, and have the canonical link point to itself. So for example, www.mysite.com/something/ would have a canonical link of href="www.mysite.com/something/" This doesn't really seem kosher to me. I thought canonical links we're suppose to point to other pages. The SEO guy claims doing it this way will tell google all these pages are indeed unique, even if they do basically have the same content. This seems a little off to me since what's to stop a spammer from putting up a million pages and doing this as well? Can anyone tell me if the SEO guy's suggestion is valid or not? If it's not valid, then do i need to figure out some way to check for duplicated items and automatically pick one of the duplicates to serve as an original and generate canonical links based off that? Thanks in advance for any help

• Bullet pattern isn't behaving as expected

  - by Fibericon

  I have a boss that's supposed to continuously shoot five streams of bullets, each at a different angle. It starts off just fine, but doesn't seem to want to use its entire array of bullets. No matter how large I set the length of bulletList, the boss simply stops shooting after a couple of seconds, then pick up again shortly. Here's what I'm using to generate the pattern: Vector3 direction = new Vector3(0.5f, -1, 0); for (int r = 0; r < boss.gun.bulletList.Length; r++) { if (!boss.gun.bulletList[r].isActive) { boss.gun.bulletList[r].direction = direction; boss.gun.bulletList[r].speed = boss.gun.BulletSpeedAdjustment; boss.gun.bulletList[r].position = boss.position; boss.gun.bulletList[r].isActive = true; break; } } direction = new Vector3(-0.5f, -1, 0); //Repeat with four similar for loops, to place a bullet in each direction It doesn't seem to matter if the bulletList length is 1000 or 100000. What could be the issue here?

• What type of pattern would be used in this case

  - by Admiral Kunkka

  I want to know how to tackle this type of scenario. We are building a person's background, from scratch, and I want to know, conceptually, how to proceed with a secure object pattern in both design and execution... I've been reading on Factory patterns, Model-View-Controller types, Dependency injection, Singleton approaches... and I can't seem to grasp or 'fit' these types of designs decisions into what I'm trying to do.. First and foremost, I started with having a big jack-of-all-trades class, then I read some more, and some tips were to make sure your classes only have a single purpose.. which makes sense and I started breaking down certain things into other classes. Okay, cool. Now I'm looking at dependency injection and kind of didn't really know what's going on. Example/insight of what kind of heirarchy I need to accomplish... class Person needs to access and build from a multitude of different classes. class Culture needs to access a sub-class for culture benefits class Social needs to access class Culture, and other sub-classes class Birth needs to access Social, Culture, and other sub-classes class Childhood/Adolescence/Adulthood need to access everything. Also, depending on different rolls, this class heirarchy needs to create multiple people as well, such as Family, and their backgrounds using some, if not all, of these same classes. Think of it as a people generator, all random, with backgrounds and things that happen to them. Ageing, death of loved ones, military careers, e.t.c. Most of the generation is done randomly, making calls to a mt_rand function to pick from most of the selections inside the classes, guaranteeing the data to be absolutely random. I have most of the bulk-data down, and was looking for some insight from fellow programmers, what do you think?

• What is the "default" software license?

  - by Tesserex

  If I release some code and binaries, but I don't include any license at all with it, what are the legal terms that apply by default (in the US, where I am). I know that I automatically have copyright without doing anything, but what restrictions are there on it? If I upload my code to github and announce it as a free download / contribute at will, then are people allowed to modify and close source my work? I haven't said that they cannot, as a GPL would, but I don't feel that it would by default be acceptable to steal my work either. So what can and cannot people do with code that is freely available, but has absolutely no licensing terms attached? By the way, I know that it would be a good idea for me to pick a license and apply it to my code soon, but I'm still curious about this. Edit Thanks! So it looks like the consensus is that it starts out very restricted, and then my actions imply any further rights. If I just put software on my website with no security, it would be an infringement to download it. If I post a link to that download on a forum, then that would implicitly give permission to use it for free, but not distribute it or its derivatives (but you can modify it for your own use). If I put it on GitHub, then it is conveyed as FOSS. Again, this is probably not codified exactly in law but may be enough to be defensible in court. It's still a good idea to post a complete license to be safe.

• Where is Oracle Utilities Application Framework V3?

  - by Anthony Shorten

  You may of noticed that the latest version of the Oracle Utilities Application Framework is V4.0.1. The last release of the Framework was V2.2. So what happened to V3? The short answer is that there is no V3 of the framework. The long answer is that the Oracle Utilities Application Framework has long been associated with Oracle Utilities Customer Care And Billing and Oracle Enterprise Taxation Management only. As more and more of the Oracle Tax And Utilities products are migrated onto the framework the association betweent eh original products on the framework is less appropriate. Therefore it was decided to pick a version number to emphasize the decouplinf of the releases of the Framework with any particular product. To illustrate this, the Oracle Mobile Workforce Management (MWM) V2.0.0 product uses Oracle Utilities Applicaton Framework V4.0.1. If we used the old numberings schema then MWM would be V4.0.1 which makes no sense, given the last release of MWM was V1.x The framework has its own development team and product management. It basicaly has its own schedule (though it is influenced by the products that use it still - which makes sense). So that s the reasoning around the version numbering change for the framework.

• Kubuntu 11.10 very slow during file I/O

  - by dko

  After updating to Kubuntu 11.10, my file I/O performance has slowly just gotten worse and worse. It is to the point where I'm getting 1 MB/s write/read speeds to the drive. If I download something, the whole machine becomes unresponsive for at times up to 30 seconds. This usually causes a timeout in the download and the download then stops. Even extracting archive files, while extracting the computer is just unusable on top of the terrible read/write speeds. It isn't the drive as I have Windows installed as well and when I boot to it I have no issues with the drive. I did not have this issue using Kubuntu 11.04 and am thinking of downgrading. However, I'd much rather help out the Ubuntu community by working through these issues. I'm starting to lean towards the new Linux Kernel is just not working well with file handles. During file I/O my system usage does pick up, but it is not 100% CPU usage. My system is as follows. Samsung 2 TB hard disk drive AMD Phenom II x6 1055 4 GB RAM (only one in use according to system monitor) ATI 5850 HD

• How to properly multi thread an RPG

  - by Nagrom_17

  I am working on an RPG type game in Java and I would like to know a few things relating to threading, What is the best way to implement a "wait for this then do this" without hanging the whole thread? Like waiting for a player to move to a location then pick up an item? or to wait one second then attack? Currently I am spawning new threads every time I need to wait for something, but that doesn't feel like the best solution. Any help is appreciated. EDIT: Clarification and an example of how I currently do things. User clicks on an item The function walkToAndPickUp(item) is called which is basically this: Make a new thread so we don't freeze the thread handling input while the player moves. Tell player to move to the item While the player is not at the item(The player moves through an update() function called in a different thread, I don't know how else to do it without freezing threads) Repeat until the player is at the item If the player is at the item then call delete item from map and add to inventory.

• Maintaining Two Separate Software Versions From the Same Codebase in Version Control

  - by Joseph

  Let's say that I am writing two different versions of the same software/program/app/script and storing them under version control. The first version is a free "Basic" version, while the second is a paid "Premium" version that takes the codebase of the free version and expands upon it with a few extra value-added features. Any new patches, fixes, or features need to find their way into both versions. I am currently considering using master and develop branches for the main codebase (free version) along side master-premium and develop-premium branches for the paid version. When a change is made to the free version and merged to the master branch (after thorough testing on develop of course), it gets copied over to the develop-premium branch via the cherry-pick command for more testing and then merged into master-premium. Is this the best workflow to handle this situation? Are there any potential problems, caveats, or pitfalls to be aware of? Is there a better branching strategy than what I have already come up with? Your feedback is highly appreciated! P.S. This is for a PHP script stored in Git, but the answers should apply to any language or VCS.

• Views : ViewControllers, many to one, or one to one?

  - by conor

  I have developed an Android application where, typically, each view (layout.xml) displayed on the screen has it's own corresponding fragment (for the purpose of this question I may refer to this as a ViewController). These views and Fragments/ViewControllers are appropriately named to reflect what they display. So this has the effect of allowing the programmer to easily pinpoint the files associated with what they see on any given screen. The above refers to the one to one part of my question. Please note that with the above there are a few exceptions where very similar is displayed on two views so the ViewController is used for two views. (Using a simple switch (type) to determine what layout.xml file to load) On the flip side. I am currently working on the iOS version of the same app, which I didn't develop. It seems that they are adopting more of a one-to-many (ViewController:View) approach. There appears to be one ViewController that handles the display logic for many different types of views. In the ViewController are an assortment of boolean flags and arrays of data (to be displayed) that are used to determine what view to load and how to display it. This seems very cumbersome to me and coupled with no comments/ambiguous variable names I am finding it very difficult to implement changes into the project. What do you guys think of the two approaches? Which one would you prefer? I'm really considering putting in some extra time at work to refactor the iOS into a more 1:1 oriented approach. My reasoning for 1:1 over M:1 is that of modularity and legibility. After all, don't some people measure the quality of code based on how easy it is for another developer to pick up the reigns or how easy it is to pull a piece of code and use it somewhere else?

• creating a tag-based website and not using programming?

  - by monodial

  I want to create a tag-based website, and I need a tool that I could use (preferably without programming). It's a site where a user could pick tags on a certain item. All tags will be placed under a group that they are logically linked to (I will do that by hand). On the other end - a visitor could choose a tag, and then be redirected to a few items on which that tag was selected the most. Besides this, I need to set up a registration form (for the visitors who want to select tags on a desired item). stackoverflow.com may serve as an example of what I want to achieve. Functionally it is a quite similar approach. I am not sure if further detailing will bring me closer to getting a development advice, but nevertheless - following this template what I would be missing on is: ability to categorize the tags; and so they would fit in one page (overall i assume <200 tags) box where a user could enter a tag and it would be pending until a certain number of users enter such tag ability to limit the number of 'questions' that appear when a visitor chooses a tag - 'question' stands for an item to which users are selecting tags (displayed items would depend on the frequency the tag was assigned - say the top two items) Which software should I try / How should I go about it? Thank you. Lukas P.S. I have bought hosting account through GoDaddy.com. This is a first website that I am trying to build.
