• Is there such thing like a "refactoring/maintainability group" role in software companies?

  - by dukeofgaming

  So, I work in a company that does embedded software development, other groups focus in the core development of different products' software and my department (which is in another geographical location) which is located at the factory has to deal with software development as well, but across all products, so that we can also fix things quicker when the lines go down due to software problems with the product. In other words, we are generalists while other groups specialize on each product. Thing is, it is kind of hard to get involved in core development when you are distributed geographically (well, I know it really isn't that hard, but there might be unintended cultural/political barriers when it comes to the discipline of collaborating remotely). So I figured that, since we are currently just putting fires out and somewhat being idle/sub-utilized (even though we are a new department, or maybe that is the reason), I thought that a good role for us could be detecting areas of opportunity of refactoring and rearchitecting code and all other implementations that might have to do with stewarding maintainability and modularity. Other groups aren't focused on this because they don't have the time and they have aggressive deadlines, which damage the quality of the code (eternal story of software projects) The thing is that I want my group/department to be recognized by management and other groups with this role officially, and I'm having trouble to come up with a good definition/identity of our group for this matter. So my question is: is this role something that already exists?, or am I the first one to make something like this up?

• What kind of permission is this? (Groups+Roles)

  - by Jorge

  I'm starting to need an access control for roles in my app. I don't know much of this, but I understand how vBulletin works: I create groups, then give permissions to groups. I think that what I need is the Role Bases Access Control (RBAC) , but i'm not sure, because I need groups to give permissions instead of single users (Maybe it's not that complicated to achieve). Example of what I'm thinking: Given a post: Editor's Group has permission to view it before it's published. Editor's Group has permission to edit its content. Public Group (Default) has not permission to view it before it's published. Admin Group has permission to delete the post. So basically I wan't orientation about if RBAC is what I need. And also, how would it be good to store group membership in a user, for example, would be good to have: ID NAME PASSWORD GROUPS (1, MyName, MyPassword, 1/2/3/4/5) and explode it via PHP or one registry for every Group membership in a table named permissions, example: USERID, USERGROUP values (1, 1), (1, 2) Maybe should be the second way because of the formal norms but I didn't study yet Databases 1 at college.

• Cloning from a given point in the snapshot tree

  - by Fat Bloke

  Although we have just released VirtualBox 4.3, this quick blog entry is about a longer standing ability of VirtualBox when it comes to Snapshots and Cloning, and was prompted by a question posed internally, here in Oracle: "Is there a way I can create a new VM from a point in my snapshot tree?". Here's the scenario: Let's say you have your favourite work VM which is Oracle Linux based and as you installed different packages, such as database, middleware, and the apps, you took snapshots at each point like this: But you then need to create a new VM for some other testing or to share with a colleague who will be using the same Linux and Database layers but may want to reconfigure the Middleware tier, and may want to install his own Apps. All you have to do is right click on the snapshot that you're happy with and clone: Give the VM that you are about to create a name, and if you plan to use it on the same host machine as the original VM, it's a good idea to "Reinitialize the MAC address" so there's no clash on the same network: Now choose the Clone type. If you plan to use this new VM on the same host as the original, you can use Linked Cloning else choose Full.  At this point you now have a choice about what to do about your snapshot tree. In our example, we're happy with the Linux and Database layers, but we may want to allow our colleague to change the upper tiers, with the option of reverting back to our known-good state, so we'll retain the snapshot data in the new VM from this point on: The cloning process then chugs along and may take a while if you chose a Full Clone: Finally, the newly cloned VM is ready with the subset of the Snapshot tree that we wanted to retain: Pretty powerful, and very useful.  Cheers, -FB

• Day in the Life of Agile - The Forge Michigan November 27, 2012

  - by csmith18119

  Went to training at The Forge yesterday and did a Day in the life of Agile with Pillar.  It was pretty good. Check them out at: http://pillartechnology.com/ Abstract: A single-day agile project simulation that is engaging, educational, provocative, and fun. This simulation introduces concepts like time-boxed iterations, User Stories, collective estimation, commitment to a product owner for iteration scope, formal verification ritual at iteration conclusion, tracking velocity, and making results big and visible through charts. The exercise is designed to simulate not only how agile teams and practices work, but the inevitable challenges that arise as teams attempt to adopt such practices. One of the best parts of this training was getting some hands on experience with agile.  We used a program called Scratch to create an arcade video game.  Our team chose Frogger.  We had 3 iterations at 20 minutes each.  I think we did pretty good but in the panic of trying to get a bunch done in only 20 minutes made it interesting. To check out our project, I uploaded it to my CodePlex site Download Source Code (Under Scratch/Frogger) Cool class! I highly recommend if you get the opportunity.

• REST API wrapper - class design for 'lite' object responses

  - by sasfrog

  I am writing a class library to serve as a managed .NET wrapper over a REST API. I'm very new to OOP, and this task is an ideal opportunity for me to learn some OOP concepts in a real-life situation that makes sense to me. Some of the key resources/objects that the API returns are returned with different levels of detail depending on whether the request is for a single instance, a list, or part of a "search all resources" response. This is obviously a good design for the REST API itself, so that full objects aren't returned (thus increasing the size of the response and therefore the time taken to respond) unless they're needed. So, to be clear: .../car/1234.json returns the full Car object for 1234, all its properties like colour, make, model, year, engine_size, etc. Let's call this full. .../cars.json returns a list of Car objects, but only with a subset of the properties returned by .../car/1234.json. Let's call this lite. ...search.json returns, among other things, a list of car objects, but with minimal properties (only ID, make and model). Let's call this lite-lite. I want to know what the pros and cons of each of the following possible designs are, and whether there is a better design that I haven't covered: Create a Car class that models the lite-lite properties, and then have each of the more detailed responses inherit and extend this class. Create separate CarFull, CarLite and CarLiteLite classes corresponding to each of the responses. Create a single Car class that contains (nullable?) properties for the full response, and create constructors for each of the responses which populate it to the extent possible (and maybe include a property that returns the response type from which the instance was created). I expect among other things there will be use cases for consumers of the wrapper where they will want to iterate through lists of Cars, regardless of which response type they were created from, such that the three response types can contribute to the same list. Happy to be pointed to good resources on this sort of thing, and/or even told the name of the concept I'm describing so I can better target my research.

• What is the correct way to implement Auth/ACL in MVC?

  - by WiseStrawberry

  I am looking into making a correctly laid out MVC Auth/ACL system. I think I want the authentication of a user (and the session handling) to be separate from the ACL system. (I don't know why but this seems a good idea from the things I've read.) What does MVC have to do with this question you ask? Because I wish for the application to be well integrated with my ACL. An example of a controller (CodeIgniter): <?php class forums extends MX_Controller { $allowed = array('users', 'admin'); $need_login = true; function __construct() { //example of checking if logged in. if($this->auth->logged_in() && $this->auth->is_admin()) { echo "you're logged in!"; } } public function add_topic() { if($this->auth->allowed('add_topic') { //some add topic things. } else { echo 'not allowed to add topic'; } } } ?> My thoughts $this->auth would be autoloaded in the system. I would like to check the $allowed array against the user currently (not) logged in and react accordingly. Is this a good way of doing things? I haven't seen much literature on MVC integration and Auth. I want to make things as easy as possible.

• Is it OK to create all primary partitions.?

  - by james

  I have a 320GB hard disk. I only use either ubuntu or kubuntu (12.04 for now). I don't want to use windows or any other dual boot os. And i need only 3 partitions on my hard disk. One for the OS and remaining two for data storage. I don't want to create swap also. Now can i create all primary partitions on the hard disk. Are there any disadvantages in doing so. If all the partitions are primary i think i can easily resize partitions in future. On second thought i have the idea of using seperate partition for /home. Is it good practice . If i have to do this, i will create 4 partitions all primary. In any case i don't want to create more than 4 partitions . And i know the limit will be 4. So is it safe to create all 3 or 4 primary partitions. Pls suggest me, What are the good practices . (previously i used win-xp and win-7 on dual boot with 2 primary partitions and that bugged me somehow i don't remember. Since then i felt there should be only one primary partition in a hard disk.) EDIT 1 : Now i will use four partitions in the sequence - / , /home , /for-data , /swap . I have another question. Does a partition need continuous blocks on the disk. I mean if i want to resize partitions later, can i add space from sda3 to sda1. Is it possible and is it safe to do ?

• MVC design patterns

  - by insane-36

  I have an application and it does not use a very good structure. However it seems to me that I have tried to stick to mvc design pattern but a senior engineer claims that I have no design patterns and code are mesh. How I have structured the code : I have couple of nsmanagedobject model classes which represents model in my case and a reskit library which encapsulates the nsurlconnection and url request. I fetch the request from the view controller itself and then when the request get completed I create predicate and then populate it in tableview. Wherever I need custom view either I create it in nib or create in a custom subclass of UIView. I have use delegation pattern and notification to communication to view controller, views and block callback with restkit. But, the senior engineer is very new to ios. He has been doing it for 2 months now but he is a good java programmer. So, what is mvc pattern ? Is core data model not working as a model objects, view controller as controller and views. I dont seem to find any other places or any other cases to create my own model object since the most of the models are used as NSManagedObject subclass.

• Java and .NET cost of use [on hold]

  - by 1110

  I work with .NET technology stack for about 4 years. I am learning and enjoy working with ASP MVC framework and I never did anything serious in other languages. This is not the question like what is better (I read all similar questions). What interest me is the cost of switching. For example: If you are about to start a start-up company today and you are in my situation not too much money, some good idea that you think others will use and have a knowledge of .NET. In my head I have a few questions that I can't answer and I know that somebody with experience can: 1) Java & .NET hosting. Suppose shared hosting is not good enough anymore, your site has grown and you need more resources. How much Java services is cheaper compared to .NET? 2) I didn't follow hype about ORACLE will kill java long time. Does oracle show interest in investing in java. I mean is is safe to bet on java as a technology when starting start-up (basically did oracle show some will to destroy java platform)? 3) I am not sure what I am asking here. When you use Java you can use JEEE stack or Java with third party stack (spring, hibernate, maven etc.). I saw a lot of project that work with second option if web application is not enterprise level but social networking site for example which stack is best pick? Summary of this question is is it safe to jump in to Java learn it and build product based on it. It's not too hard for me to learn it. But how much can I get from it.

• Developing an Interface to a Dynamic System

  - by radix07

  I work for a small company and have been designing a GUI to interface our embedded system. The problem with this embedded system is that it is not a finished product (may never be) and is constantly under development and being tweaked and updated for different customers and applications in small volumes. So to deal with this I made a program that can export all the data from a spreadsheet where most of the embedded system variables are sourced from and throw them into a small database for the GUI application to use. This database program I made also spits out a cross reference file for the embedded system which allows the GUI to look up all the variables. This system works pretty well so far, and is even integrated with version control among the GUI, database, and embedded system. The big problem is that there is constant development on several projects that use this system and it gets terribly tedious to keep the system up to date and bring in new changes. This has gotten to the point to where I have had to code the GUI to dynamically (generically) generate all interfaces since I am never guaranteed to find the same data the same way. I have not been able to come up with a good way to uniquely identify the data I import from excel since all fields are able to be changed (due to engineering stubbornness, code re-factoring and/or excel issues) and I cannot assign a fixed reference within the sheet itself. So, are there any good methods or ideas on how to handle the chaos?

• Which powerful laptop, with UK keyboard and 8gb ram

  - by RobinL

  I've been searching high and low for high spec laptops compatible with Ubuntu. The lack of coherent information on the topic is high (considering the number of people who apparently want a good laptop with an OS operating system). So I thought you may have some advice. My requirements: a) has = 8Gb ram b) is compatible with Ubuntu c) has a UK keyboard and charger d) does not cost the Earth Which would you go for? Does anyone have good experience with high-end laptops running Ubuntu? So here's some background research: Samsung Series 7 looks great, but has various problems on Ubuntu, including: poor battery life, touchpad does not work, graphics card not fully supported and sucks power when it does (see [here] and [here], for example). Other options on the [wish list] include: the sensible [Acer] (possibly n.1 choice, but not sure about graphics card compatibility or battery), a nice looking [HP Pavilion dv6-6c56ea], which also has incompatibility issues (see [here] and [here] and check ubuntuforums) And another [Acer] which may be best due to its simplicity and cheapness. Other sub-questions: didn't Dell offer Ubuntu support for decent laptops (above 6Gb ram their offerings are scarce); what about pre-installed options such as those provided by System76? If it weren't for the UK keyboard and charger, I'd probably go for this [amazing-looking] [machine]. Many thanks for any advice, P.s. Apologies for lack of hyperlinks; I'm a noob so only allowed 2 :( All 10 links are available here though for the interested reader :) Robin

• When creating a GUI wizard, should all pages/tabs be of the same size? [closed]

  - by Job

  I understand that some libraries would force me to, but my question is general. If I have a set of buttons at the bottom: Back, Next, Cancel?, (other?), then should their location ever change? If the answer is no, then what do I do about pages with little content? Do I stretch things? Place them in the lone upper left corner? According to Steve Krug, it does not make sense to add anything to GUI that does not need to be there. I understand that there are different approaches to wizards - some have tabs, others do not. Some tabs are lined horizontally at the top; others - vertically on the left. Some do not show pages/tabs, and are simply sequences of dialogs. This is probably a must when the wizard is "non-linear", e.g. some earlier choices can result in branching. Either way the problem is the same - sacrifice on the consistency of the "big picture" (outline of the page/tab + location of buttons), or the consistency of details (some tabs might be somewhat packed; others having very little content). A third choice, I suppose is putting extra effort in the content in order to make sure that organizing the content such that it is more or less evenly distributed from page to page. However, this can be difficult to do (say, when the very first tab contains only a choice of three things, and then branches off from there; there are probably other examples), and hard to maintain this balance if any of the content changes later. Can you recommend a good approach? A link to a relevant good blog post or a chapter of a book is also welcome. Let me know if you have questions.

• using NetBeans for rotate a figure in a label [migrated]

  - by user134812

  I was reading this post: http://forums.netbeans.org/post-8864.html and what I have done so far is to make a jFrame in NetBeans, on it I have drawn a jPanel and inisde the panel I have drawn a jLabel on it and use the icon property to put an image on it; until now all is so far so good. I would like to make a program that everytime I click on the figure it rotates it to the right. Actually I have found the following code: public class RotateImage extends JPanel{ // Declare an Image object for us to use. Image image; // Create a constructor method public RotateImage(){ super(); // Load an image to play with. image = Toolkit.getDefaultToolkit().getImage("Duke_Blocks.gif"); } public void paintComponent(Graphics g){ Graphics2D g2d=(Graphics2D)g; // Create a Java2D version of g. g2d.translate(170, 0); // Translate the center of our coordinates. g2d.rotate(1); // Rotate the image by 1 radian. g2d.drawImage(image, 0, 0, 200, 200, this); } but for what I see this code is for making the panel and other components from scratch, for my purposes it is not so good because I need to put several figures on my jFrame. Could somebody can give me a hint how to do this?

• Where to find information about ubuntu compatible or certified hardware/PC models

  - by Halkinn

  I am buying a new desktop PC in early 2013, anyway this question should apply to someone intending to buy a new laptop/ultrabook as well. This machine is not meant for gaming, and if I ocasionally do it, I can survive with minimum graphics. However I may need some heavy multimedia edition or multitasking at times, so basically my greatest priority is a good processor, after that perhaps average graphic card (if onboards are not enough, I am still not informed enough about that), at least 4GB of RAM with possibility of expansion. I know there are some PC models specially designed to ship with Ubuntu, which is the OS I use the most these days. However, most people around me use Windows and some software with unsupported versions for Linux and not having a Windows license becomes a bit problematic. Given that, I would like to find information about which PC models or even manufacters currently on the market have the best compatibility with Ubuntu, I am still undecided between building my own desktop or buying a pre-made model, so I would like to find information both for certified models and certified hardware or even Ubuntu partners that may work closely with Canonical. Where to find this information in order to make sure that I will have a good experience with Ubuntu on my new PC in the years to come?

• How to learn to deliver quality software designs when working on a tight deadline?

  - by chester89

  I read many books about how to design great software, but I kind of struggle to come up with a good design decisions when it comes to business apps, especially when the timeframe is tough. In the company I currently work for, the following situation happen all the time: my teamlead tells me that there's a task to do, I call some guy or a girl from business who tells me exactly what is it they want, and then I start coding. The task always fits in some existing application (we do only web apps or web services), usually it's purpose is to pull data from one datasource and put into the other one, with some business logic attached in the process. I start coding and then, after spending some time on a problem, my code didn't work as expected - either because of technical mistake or my lack of knowledge of the domain. The business is ringing me 2-3 times a day to hurry me up. I ask my team lead to help, he comes up, sees my code and goes like 'What's this?'. Then he throws away about half of my code, including all the design decisions I made, writes 2-3 methods that does the job (each of them usually 200-300 lines long or more, by the way), and task is complete, code works as it should have. The guy is smarter than me, obviously, and I'm aware of that. My goal is to be better software developer, that means write better code, not finish the job quicker with some crappy code. And the thing is, when I have enough time to tackle a problem, I can come up with a design that is good (in my opinion, of course), but I fall short to do so when I'm on a tight deadline. What should I do? I am fully aware that it's rather vague explanation, but please bear with me

• How can I go about learning to write a shader

  - by Donutz

  So here's the background: I'm writing a game, just for my own amusement and education really. I've already come to the conclusion that XNA was the way to go for graphics, I've bought a couple of books, I've gotten basic game graphics going, and that's great. Now I'm starting to get a little in-depth and I'm starting to need to do stuff not covered in my (beginner) books. In particular, I need to display a sprite using a mask. Actually, what I need to do is display a generic sprite with a different color for each player. After banging around on the web, it seems the way to go is to have a color texture (one for each player) which I display using the mask, then display the generic part of the sprite. This has to be done dynamically, i.e. at runtime because there are too many sprites to keep in memory if I try to generate all the permutations at startup. So, I need to use a shader. Fine. I've downloaded a sample shader program, and managed to hit it with a hammer until it does something close enough to what I want so that I know I'm on the right track. And here, we come to my problem... I have no friggin' clue what I'm doing. While there are a lot of samples and such about shaders, no one ever actually explains what's going on. For instance, I can't find any real docs on Tex2D. I feel like the guys in Zoolander poking at the computer. So, my question (yes, I have a question) -- where is a good URL or what is a good book to take me from dumskie to reasonably competent to write a basic shader?

• AngularJS dealing with large data sets (Strategy)

  - by Brian

  I am working on developing a personal temperature logging viewer based on my rasppi curl'ing data into my web server's api. Temperatures are taken every 2 seconds and I can have several temperature sensors posting data. Needless to say I will have a lot of data to handle even within the scope of an hour. I have implemented a very simple paging api from the server so the server doesn't timeout and is currently only returning data in 1000 units per call, then paging through the data. I had the idea to intially show say the last 20 minutes of data from a sensor (or all sensors depending on user choices), then allowing the user to select other timeframes from which to show data. The issue comes in when you want to view all sensors or an extended time period (say 24 hours). Is there a best practice of handling this large amount of data? Would it be useful to load those first 20 minutes into the live view and then cache into local storage something like the last 24 hours? I haven't been able to find a decent idea of this in use yet even though there are a lot of ways to take this problem. I am just looking for some suggestions as to what might provide a good balance between good performance and not caching the entire data set on the client side (as beyond a week of data this might not be feasible).

• How to build an API on top of an existing Rails app with NodeJs and what architecture to use?

  - by javiayala

  The explanation I was recently hired by a company that has an old RoR 2.3 application with more than 100k users, a strong SEO strategy with more than 170k indexed urls, native android and ios applications and other custom-made mobile and web applications that rely on a not so good API from the same RoR app. They recently merged with a company from another country as an strategy to grow the business and the profit. They have almost the same stats, a similar strategy and mobile apps. We have just decided that we need to merge the data from both companies and to start a new app from scratch since the RoR app is to old and heavily patched and the app from the other company was built with a custom PHP framework without any documentation. The only good news is that both databases are in MySQL and have a similar structure. The challenge I need to build a new version that: can handle a lot of traffic, preserves the SEO strategies of both companies, serve 2 different domains, and have a strong API that can support legacy mobile apps from both companies and be ready for a new set of native apps. I want to use RoR 3.2 for the main web apps and NodeJs with a Restful API. I know that I need to be very careful with the mobile apps and handle multiple versions of the API. I also think that I need to create a service that can handle a lot IO request since the apps is heavily used to create orders for restaurants at a certain time of the day. The questions With all this in mind: What type of architecture do you recommend me to follow? What gems or node packages do you think will work the best? How do I build a new rails app and keep using the same database structure? Should I use NodeJS to build an API or just build a new service with Ruby? I know that I'm asking to much from you guys, but please help me by answering any topic that you can or by pointing me on the right direction. All your comments and feedback will be extremely appreciated! Thanks!

• WiFi problems on several Ubuntu installations

  - by Rickyfresh

  Okay this is the first time I have ever had to ask a question as usually the Ubuntu community have answered everything already but on this occasion there are many people asking for the answer but not one good solution has become available so far so someone please help or I will have to install Windows on my sons and my girlfriends PCs and that would be a disaster as I am trying to help convince people to move from Windows. I installed 12.04 on three computers on the same day. Dell Inspiron (Works Perfect) Toshiba Satellite Home built Desktop The Dell works perfect but the other two either keep losing connection to the wireless Internet and even when they are connected they stop connecting to web sites, for some reason it searches Google fine but will not connect to web sites when a link is clicked. So far people have recommended in other forums: Removing network manager and installing wicd (didn't solve it) Changing the MTU in the wireless settings (didn't solve it) All sorts of messing about with Firefox settings (this doesn't solve it and even if it did this would leave most average PC users scratching their heads and wishing they had stuck to windows) The problem exists on two very different machines and different wireless cards so I doubt its a driver or hardware issue, also many other Ubuntu users are having the same problem with a vast array of different machines and wireless cards. Can someone please give a good solution to this as its going to turn a lot of people away from Ubuntu if they cannot get this sorted. I would give some PC specs but the two machines are vastly different and the other people complaining of this problem also have very different systems all showing the same problem.

• Why does printf report an error on all but three (ASCII-range) Unicode Codepoints, yet is fine with all others?

  - by fred.bear

  The 'printf' I refer to is the standard-issue "program" (not the built-in): /usr/bin/printf I was testing printf out as a viable method of convert a Unicode Codepoint Hex-literal into its Unicoder character representation, I was looking good, and seemed flawless..(btw. the built-in printf can't do this at all (I think)... I then thought to test it at the lower extreme end of the code-spectrum, and it failed with an avalanche of errors.. All in the ASCII range (= 7 bits) The strangest thing was that 3 value printed normally; they are: $ \u0024 @ \u0040 ` \u0060 I'd like to know what is going on here. The ASCII character-set is most definitely part of the Unicode Code-point sequence.... I am puzzled, and still without a good way to bash script this particular converion.. Suggestions are welcome. To be entertained by that same avalanche of errors, paste the following code into a terminal... # Here is one of the error messages # /usr/bin/printf: invalid universal character name \u0041 # ...for them all, run the following script ( for nib1 in {0..9} {A..F}; do for nib0 in {0..9} {A..F}; do [[ $nib1 < A ]] && nl="\n" || nl=" " $(type -P printf) "\u00$nib1$nib0$nl" done done echo )

• Value my C++ knowledge

  - by PirateOwh

  I have only followed antiRTFM tutorials and read 2 books So, I'll list the things I know better : basic input output and all the variables : integers ( signed unsigned ), float, double, char arrays if, for, while, switch functions, and passing variables to functions and return type thing classes and the concept of oop with separating declaration and definition in the header and in the source pointers so this and some more i think is all i know of C++.. But, i need some exercises to test my knowledge because i want to move on to the library SDL, so I don't know if i should feel ready or not to move on to something totally different.. I feel I should know the basics for good at least. So the question is : How can i value my c++ knowledge? Is there any online tests? Is there any GDD ( Game Design Document ) for free to use and see if i can manage to do it so "i'd pass" ? ( I'm saying GDD since ill move on to SDL and try to make my own game ) When should I move to SDL? What are ALL the things I should "master" ( master is a big word to say.. but so you understand what i mean ) before moving on ? Please I'm really in need of expert advice. I think my question is detailed so i hope you understand what i mean and can give me a good reply. Thanks for the help!

• Which are the best ways to organize view hierarchies in GUI interfaces?

  - by none

  I'm currently trying to figure out the best techniques for organizing GUI view hierarchies, that is dividing a window into several panels which are in turn divided into other components. I've given a look to the Composite Design Pattern, but I don't know if I can find better alternatives, so I'd appreciate to know if using the Composite is a good idea, or it would be better looking for some other techniques. I'm currently developing in Java Swing, but I don't think that the framework or the language can have a great impact on this. Any help will be appreciated. ---------EDIT------------ I was currently developing a frame containing three labels, one button and a text field. At the button pressed, the content inside the text field would be searched, and the results written inside the three labels. One of my typical structure would be the following: MainWindow | Main panel | Panel with text field and labels. | Panel with search button Now, as the title explains, I was looking for a suitable way of organizing both the MainPanel and the other two panels. But here came problems, since I'm not sure whether organizing them like attributes or storing inside some data structure (i.e. LinkedList or something like this). Anyway, I don't really think that both my solution are really good, so I'm wondering if there are really better approaches for facing this kind of problems. Hope it helps

• decouple software components via nameconvention

  - by csteinmueller

  I'm currently evaluating alternatives to refactor a drivermanagement. In my multitier architecture I have Baseclass DAL.Device //my entity Interfaces BL.IDriver //handles the dataprocessing between application and device BL.IDriverCreator //creates an IDriver from a Device BL.IDriverFactory //handles the driver creation requests Every specialization of Device has a corresponding IDriver implementation and a corresponding IDriverCreator implementation. At the moment the mapping is fix via a type check within the business layer / DriverFactory. That means every new driver needs a) changing code within the DriverFactory and b) referencing the new IDriver implementation / assembly. On a customers point of view that means, every new driver, used or not, needs a complex revalidation of their hardware environment, because it's a critical process. My first inspiration was to use a caliburn micro like nameconvention see Caliburn.Micro: Xaml Made Easy BL.RestDriver BL.RestDriverCreator DAL.RestDevice After receiving the RestDevicewithin the IDriverFactory I can load all driver dlls via reflection and do a namesplitting/comparing (extracting the xx from xxDriverCreator and xxDevice) Another idea would be a custom attribute (which also leads to comparing strings). My question: is that a good approach above layer borders? If not, what would be a good approach?

• I need a decent alternative to c++ [closed]

  - by wxiiir

  I've learned php and c++, i will list the things i liked and didn't liked on each of them, how i decided to learn them in the first place and why i feel the need to learn a decent alternative to c++, i'm not a professional programmer and only do projects for myself. PHP - Decided to learn because i wanted to build a dynamic website, that i did and turned out very good, i even coded a 'not so basic' search engine for it that would display the results 'google style' and really fast, pretty cool stuff. PROS - Pretty consistent syntax for all stuff (minor caveats), great functionality, a joy for me to code in it (it seems to 'know' what i want it to do and just does it) CONS - Painfully slow for number crunching (which takes me to c++ that i only learned because i wanted to do some number crunching and it had to be screaming fast) C++ - Learned because number crunching was so slow in php and manipulating large amounts of data was very difficult, i thought, it's popular programming language and all, and tests show that it's fast, the basic stuff resemble php so it shouldn't be hard to pick up PROS - It can be used to virtually anything, very very fast CONS - Although fun to code at the start, if i need to do something out of the ordinary, memory allocation routines, pointer stuff, stack sizes etc... will get me tired really quick, syntax is a bit inconsistent some times (more caveats) I guess that from what i wrote you guys will understand what i'm looking for, there are thousands of languages out there, it's likely that one of them will suit my needs, i've been seeing stuff today and a friend of mine that is a professional programmer tried OCaml and Fortran and said that both are fast for numerical stuff, i've been inclined to test Fortran, but i need some more input because i want to have some other good 'candidates' to choose from, for example the python syntax seemed great to me, but then i found out from some tests that it was a lot slower than c++ and i simply don't want to twiddle my thumbs all day.

• I want to make "stuff" on the web, is a BsC. in Computers necessary/overkill? [on hold]

  - by notypist

  I'm 24 and have a lead role in a major news outlet in my country, with a good pay and public image in the horizon. I hold a job that was previously held by people with 15-20 years of experience and considered one of the top 5 news anchors in my country. My passion though, is computers. The web, to be precise. I was a problogger at a very young age. I hacked my way through CSS and some basic HTML and PHP. But I want to move forward - I want to CREATE not just STRUCTURE things. Giving up the present (and especially the seemingly promising future) in my current industry is hard, my friends raise their eyebrows... I'm considering a BsC. in computer Engineering - but my stats are short of getting into a good university for this discipline. Plus, I'm not the best with math - although I do exceptionally well in statistics and other numbers that are more applicable to real life. I tried learning PHP through online websites, but that just "doesn't cut it" for me. Nope. So what are my options here? if I don't want to build hardware or and deal with overly-complex algorithmic but would like, for example - to build a well functioning iPhone and iPad app, or a SaaS, a startup...do I have to go the BsC. route? I don't see any option to get an "official" education in strictly "web" concepts and languages.. Note: I'm well off financially, so I'm doing this more to be able to create stuff, rather than get a job in a corporations. Although if I land somewhere high, that might be an option. But my main concern is getting the tools.
