• Changing domain name - what are the practical steps involved

  - by Homunculus Reticulli

  I launched a website a couple of years ago, bright eyed and bushy tailed, with dreams of conquering the world. Unfortunately it wasn't to be. Now, that I am a bit older and wiser, I have spent some money on branding and creating more quality content etc, I am rebranding and relaunching the site with a new domain name. Although the traffic on the old site is laughable (i.e. non-existent), there are a few pages of good information on there and I don't want to lose any "juice" those pages may have gained because web crawlers have been seeing it for a few years now. Ok, the upshot of all that is this: I want to change my domain name from xyz.com to abc.com. I am maintaining the same friendly urls I had before, only the domanin name part of the url will change, so that any traffic coming to the old page will be forwarded/redirected? to the new page seamlessly. How do I go about achieving this (i.e. what are the steps I need to carry out, and to minimize any "disruption" to any credibility the existing site has with Googlebot etc? I am running Apache 2.x on a headless Linux (Ubuntu) server.

• Why do I need a framework?

  - by lvictorino

  First of all I know my question may sounds idiot but I am no "beginner". In fact I work as game developer for several years now and I know some things about code :) But as this is no related to game development I am a bit lost. I am writing a big script (something about GIS) in Python, using a lot of data stored in a database. I made a first version of my script, and now, I'd like to re-design the whole thing. I read some advice about using a framework (like Django) for database queries. But as my script only "SELECT" informations I was wondering about the real benefits to use a framework. It seems that it adds a lot of complexity and useless embedded features (useless for my specific script) for the benefits that it will bring. Am I wrong? EDIT: few spec of this "script". Its purpose is to get GIS data on an enormous database (if you ever worked with openstreetmap you know what I mean ~= 200Go) and to manipulate this data in order to produce nice map images. Queries are not numerous (select streets, select avenues, select waterways, select forests... and so on for a specific area) but query results may be more than 10.000 rows. I'd like to sell this script as a service, so yes it's meant to stay.

• My 2012 Professional Development Goals

  - by kerry

  Once again I am going to declare some professional goals for my upcoming year. Convert my blog to Jekyll hosted on github – I am tired of wordpress, tired of spam, and would like to try something new.  I have already started on this.  Just need to finish it up. Launch my GWT / Google App Engine application – I am currently developing a GWT application to be deployed to Google App Engine. Do another presentation at the user group – At least a few lightning talks.  I have a few ideas. Attend a tech conference – Dev Nexus is the likely target Post more often – I did 10 posts last year, would like to maybe double that next year (including this one) Attend a user group meeting outside of Nashville JUG – A rollover from last year, I will probably be regularly attend the Interactive Developers meeting Study another language – I have been thinking about looking in to Dart or perhaps Go Launch an Android app – Another holdover from last year I am thinking of doing a small app having to do with managing the silent state of the phone

• How to deal with the need to know multiple programming languages? When to stop learning new languages?

  - by Raphael

  I am a relatively young programmer. I am 23 and I have been programming professionally for about 5 years. As most programmers I started with C, learned some x86 assembly for fun and then I found C++ which turned out to be my greatest passion in the programming world. Programming with C and C++ forces you to learn platform specific APIs, libs and frameworks all of each requires constant study and experimentation. After some time I had to move on to Java and C# as the demand on my region is basically for these languages. With these languages I entered the world of web development and then I had to learn javascript. Developing for the .NET Framework was exciting at first but I constantly felt as I was getting tied up by Microsoft (and of course the .NET Framework was driving me away from Linux). For desktop development I could do pretty much everything I did with .NET using C++ with Qt but for web development I had to look for an alternative. Quickly I found Django and then I proceeded to learn Python so I could use Django. Nowadays I am learning iOS development with Objective-C. So far it was pretty much easy to learn all these languages (C++ trained me well) but I am worried that someday I won't be able to keep track of them all. Just to clarify. The only languages I learned cause I had to were C# and Java. All of the others I learned for fun, because I love programming and learning new things. Also I like to keep my skills sharp on desktop, web and mobile development. My question is: How do you keep track of multiple programming languages? (I mean, keep track of changes to these languages and keep your skills sharp) and: Is there such a thing as enough programming languages?

• How to make a good portfolio for IT student (who loves programming) like me?

  - by Viet

  I am currently a college student, and going to apply for an university in probably next month. Unlike art student who easily put on their works such as models, designs and so on on their portfolio; I am hitting a dead corner trying to find a "creative" way to showcase my work as a programmer. It would be normal if programmer shows his good project with source code and everything else. Well, it should be no problem with actual "good" projects, but all of my projects are crappy (can't help it because I am still student, and don't have much work experience) and I don't even know it's worth to show. Nonetheless, I have learned a lot in only 1 year since I started programming. I am now familiar with Java, PHP, Actionscript3, C#, Objective-C and on my way to learn Ruby. I plan to build a Flash portfolio using Actionscript with Ruby as backend to show what I have learnt. The problem is idea. How to show people that I learned a lot of useful thing? Otherwise I hit the dead end and LOL just show what I have on Github (but i certainly never want that...)

• Provide an OnChange event for an internal property which is controlled externally?

  - by NGLN

  For fun and by request I am updating this ImageGrid component, a kind of listbox for images that has a FileNames property of type TStrings. For ease of writing, I have been misusing its FileNames.Objects property for bitmap storage. But since the TStrings type suggests that users of the component could or would want to use the Objects property for custom data, e.g. like TListBox.Items, I am rewriting the component to store the bitmaps elsewhere and leave FileNames.Objects untouched for unknown future usage. Now I am wondering whether to provide an OnChange event. And if so, whether to fire it when one or more FileNames.Objects changes. Trying to answer it myself, I dove in Delphi's own VCL and stumbled on: TMemo: has an OnChange event, but ignores Lines.Objects TListBox: has no OnChange event, but is capable of storing Items.Objects TStringGrid: has no OnChange event, but is capable of storing Objects, Rows.Objects, Cols.Objects So now I am somewhat puzzeled, because I cannot imagine Borland's developers didn't add events for several Objects properties out of ease. Sure, when a user changes a FileNames.Object in my component, he knows he does and could implement appropriate interaction himself. But wouldn't it be convenient when the component does automatically? What would you expect from this component in this regard?

• How to sell logistical procedures that require less time to perform but more finesse?

  - by foampile

  I am working with a group where part of the responsibilities is managing a certain set of configuration files which, of course, have the same skeleton/structure across different environments but different values (like server, user, this setting, that setting etc.). Pretty classic scenario... The problem is that everyone just goes and modifies final, environment-specific files and basically repeats the work for every environment. Personally, I am offended to have to peform repeatable, mundane tasks in this day and age when we have technologies to automate it all. So I devised a very simple procedure of abstracting the files into templates, stubbing env-specific values with parameters and then wrote a simple Perl script that, given a template and an environment matrix with env-specific values for each param, produces the final file. So this is nothing special, cutting-edge or revolutionary -- I am pretty sure that 20 years ago efficient places did their CM like that. However, that requires that changes are made at the template level and then distributed across different environments using the script and not making changes in the final environment-specific files. This is where I am encountering resentment as they feel "comfortable" doing it their old, manual, repeated labor way. Personally, I don't have a problem with them working hard rather than smart but the problem is when I have to build on top of someone else's changes, I have to merge their changes into my template from a specific file, which takes time and is grueling. So my question is how to go about selling my method, which makes it so much faster in an environment that is resentful to change and where most things have to be done at the level of the least competent team member?

• ASP.NET design not SOLID

  - by w0051977

  SOLID principles are described here: http://en.wikipedia.org/wiki/SOLID_%28object-oriented_design%29 I am developing a large ASP.NET app. The previous developer created a few very large classes each with lots of different purposes. It is very difficult to maintain and extend. The classes are deployed to the web server along with the code behind files etc. I want to share a small amount of the app with another application. I am considering moving all of the classes of the ASP.NET web app to a DLL, so the small subset of functionality can be shared. I realise it would be better to only share the classes which contain code to be shared but because of the dependencies this is proving to be very difficult e.g. class A contains code that should be shared, however class A contains references to classes B, C, D, E, F, G etc, so class A cannot be shared on its own. I am planning to refactor the code in the future. As a temporary solution I am planning to convert all the classes into a single class library. Is this a bad idea and if so, is there an alternative? as I don't have time to refactor at the moment.

• Ubuntu 12.04 Network Manager: unable to save manual setting to set up a static ip

  - by Andy

  I am fairly familiar with setting up servers, and ubuntu is generally my flavor of choice, but I just installed 12.04 desktop and I am seeing some behavior in network manager that is really puzzling. The network connection works fine if I leave it set on dhcp, but I would like a static IP address for my new web server. When I go into network manager and edit the connection for the one and only NIC I can select MANUAL from the dropdown menu but as soon as I do the Save button becomes greyed out. Even after filling out all fields for the connection it is still grey and I am unable to save the static IP connection information. Any thoughts would be greatly appreciated. I'm hoping there is just some new setting that I am unaware of.... On another note, if I stop the network manager and go edit the interfaces file (and the appropriate hosts/routes/dns files), I do get a static ip address assigned and I can contact my server from the outside, however, the server cannot find the internet. Can't ping even its own ip... I can ping the loopback interface though. I'm really confused on this one. Hoping someone can offer some help.

• What are some efficient ways to set up my environment when working on a remote site?

  - by Prefix

  Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

• Finding the shortest path through a digraph that visits all nodes

  - by Boluc Papuccuoglu

  I am trying to find the shortest possible path that visits every node through a graph (a node may be visited more than once, the solution may pick any node as the starting node.). The graph is directed, meaning that being able to travel from node A to node B does not mean one can travel from node B to node A. All distances between nodes are equal. I was able to code a brute force search that found a path of only 27 nodes when I had 27 nodes and each node had a connection to 2 or 1 other node. However, the actual problem that I am trying to solve consists of 256 nodes, with each node connecting to either 4 or 3 other nodes. The brute force algorithm that solved the 27 node graph can produce a 415 node solution (not optimal) within a few seconds, but using the processing power I have at my disposal takes about 6 hours to arrive at a 402 node solution. What approach should I use to arrive at a solution that I can be certain is the optimal one? For example, use an optimizer algorithm to shorten a non-optimal solution? Or somehow adopt a brute force search that discards paths that are not optimal? EDIT: (Copying a comment to an answer here to better clarify the question) To clarify, I am not saying that there is a Hamiltonian path and I need to find it, I am trying to find the shortest path in the 256 node graph that visits each node AT LEAST once. With the 27 node run, I was able to find a Hamiltonian path, which assured me that it was an optimal solution. I want to find a solution for the 256 node graph which is the shortest.

• Should CV contain cases where certain party fools me and not pay salary? Is it "holiday" time or not?

  - by otto

  Suppose I am fooled to work in a start-up or a company that has been a very small over a long time, let say 10 years. I work them 3 months and I really enjoy the work -- I learn a lot of new skills such as Haskell, MapReduce, CouchDB and many other little things. Now the firm did not pay any salary: A) I may be unskilled, B) I did not meet some deadline (I don't know because I am not allowed to speak to the boss but I know that I am not getting any payment) or C) I was fooled. Some detail about C I heard that the firm have had similar cases from my friend, "The guy X was there and he said he does not trust the firm at all so he went to other firm". I don't know what the term "trust" mean here, anyway the firm consists of ignorant drop-outs that hires academic people, a bit irony. They hire people from student-organizations and let them work and promise ok -compensation but -- when you start working the co-employer starts all kind of instructions "Do not work so hard, do not work so long, do not work so much" -- it is like he is making sure you do not feel sad when he does not pay any salary (co-employer is an owner in the firm). Anyway, I learnt a ton in the company but it was very inefficient working. I worked only alone, not really working in a "company". Now should by resume contain references to the firm and the guy who did not pay me anything? Or should my resume read that I worked in XYZ -technologies -- but 1 year's NDA -- what can write here? Now I fear that if I put the firm to my resume: they will lie about my input to my next employer. I feel they are very dishonest. On the other hand, I want to make it sure that I have worked over the time. So: Should my CV contain the not-so-good or even awful employers that may be fooling people to work there? I am pretty sure everyone knows the firm and its habbits, circles are small but people are afraid to speak.

• Employers and intellectual property 2

  - by Rick

  I have a question about intellectual property, I am currently a manager in a small manufacturing firm. The owners are driven by greed and don't appreciate the development process of complex machinery and are happy just to send things out half done. I on the other hand think that it should be done properly as breakdown in the field can be costly, embarrassing. They seem to have all of us running around doing most of the work out of hours using the attitude of "Be grateful to have a job" yet no one has a contract or any security or any agreement in place. For a couple of the projects i am using PLC's and doing the code in my own time and the testing during company time, and i am aware that they cannot support their own machines if i left, but as i created the code in my own time who owns it? The have asked my to put in a shutdown code for a maintenance request after a given length of time, could this be classed as criminal damage or anything illegal apart from immoral? (we sell the machines with 12 month warrantee, shut down after) But as time goes on I'm getting rather fed up of the companies attitude toward the client. I am considering keeping the clients as my own and get them to contact me directly In the shutdown code. By doing something like this is a trial version contact me for a full license? I wouldn't feel bad for my current employer as he is not afraid to S***t on people as he has been evolved in numerous law suits and has over 30 failed companies leaving people and customers high and dry, we have took the company this far on the reputation of the workers and and i can see things heading like all the other companies he has owned and taking our reputations with him. So i suppose now i have set the scene, if i code into it to contact me directly in the shutdown could there be any legal impact on me, as i rightly or wrongly think i own the code and designs? Cheers R

• Should one reject over-scoped projects?

  - by Little Child

  I spoke to my first potential client today and he told me about the requirements of his project - an Android app. He is a well-known designer / photographer in my country and now wants me to "convert the website into an app, custom-tailored". So the requirements, details stripped out, are as follows: eCommerce Aggregating all his content like videos, blogs, tweets, etc. into the app Live streaming any of his studio demos Augmented reality. So that people can see what his painting will look like on their wall before they buy it Taxi Sharing Now, for a freelance project, it seems too over-scoped. I am not saying that I cannot do it. I can. But let me be realistic: There is a steep learning curve when it comes to VR. I am not a tester. I have never white-box tested my own apps. I always black-box test. Since he is a renowned artist, something short of perfect might harm his public image So, I asked him for 2 weeks' worth of time before I give him the final answer. Now knowing whom to consult for advise, I am posting the question here. Although interesting and personally challenging, I am split-minded about accepting a project like this. I will be the only developer for this. Should one reject a project that seems to be over-scoped for one's own abilities?

• Problems when rendering code on Nvidia GPU

  - by 2am

  I am following OpenGL GLSL cookbook 4.0, I have rendered a tesselated quad, as you see in the screenshot below, and i am moving Y coordinate of every vertex using a time based sin function as given in the code in the book. This program, as you see on the text in the image, runs perfectly on built in Intel HD graphics of my processor, but i have Nvidia GT 555m graphics in my laptop, (which by the way has switchable graphics) when I run the program on the graphic card, the OpenGL shader compilation fails. It fails on following instruction.. pos.y = sin.waveAmp * sin(u); giving error Error C1105 : Cannot call a non-function I know this error is coming on the sin(u) function which you see in the instruction. I am not able to understand why? When i removed sin(u) from the code, the program ran fine on Nvidia card. Its running with sin(u) fine on Intel HD 3000 graphics. Also, if you notice the program is almost unusable with intel HD 3000 graphics, I am getting only 9FPS, which is not enough. Its too much load for intel HD 3000. So, sin(X) function is not defined in the OpenGL specification given by Nvidia drivers or something else??

• Vector-based fonts vs. bitmap fonts in (2d) games?

  - by jmp97

  I know that many games are using bitmap fonts. Which are the advantages for vector-based font rendering / manipulation when compared to bitmap fonts and in which scenarios would they matter the most? Prefer a focus on 2d games when answering this question. If relevant, please include examples for games using either approach. Some factors you might consider: amount of text used in the game scaling of text overlaying glyphs and anti-aliasing general rendering quality font colors and styling user interface requirements localisation / unicode text wrapping and formatting cross-platform deployment 2d vs 3d Background: I am developing a simple falling blocks game in 2d, targeted for pc. I would like to add text labels for level, score, and menu buttons. I am using SFML which uses FreeType internally, so vector-based features are easily available for my project. In my view, font sizes in simple games often don't vary, and bitmap fonts should be easier for cross-platform concerns (font-formats and font rendering quality). But I am unsure if I am missing some important points here, especially since I want to polish the looks of the final game.

• Is file permission secured when it transferred from Ubuntu to Windows?

  - by Gaurav_Java

  I am having 9GB text file which is encrypted . This file contains some confidential data . Which is on my system(Ubuntu) and my external HDD (ntfs) . This file get daily updated and then encrypted . But it has to be shared among 2-3 (Windows) person. I defined permission so that no other person can even read this file(chmod 660). It is too large file, so I can't upload it anywhere and it get updated daily basis. But this file travel on Windows OS and Ubuntu also. Even I am having copy of this on my personal computer. Recently it was deleted by some other user over Windows . I just want to know how can I set permission over that file so that it cannot be deleted from any other operating system. If someone delete this file, then I am having data old for couple of days, which is only on my system. I gone through this question it says there is nothing. And from this question I am not able to understand how can I protect it. Can I do anything for preventing this file from being deleted. Then how can I secure this files from getting deleted any suggestion or software or ideas. Maybe I sound silly or this is stupid question. Please don't close it, thanks for any suggestion or solution.

• Can certain system-hungry modules be disabled in Ubuntu?

  - by Ole Thomsen Buus

  Hi, Let me add some context: I am currently using Ubuntu 9.10 64-bit (Desktop) on a relatively powerful stationary PC (Intel Core i7 920, 12GB ram). My purpose is highspeed imaging with a pointgrey Grashopper machine-vision camera (for research, PhD project). This camera is capable of 200 fps at full VGA (640x480) resolution. The camera is connected using Firewire (1394b) and the drivers and software from Pointgrey works great. I have developed a console C++ application that can grap a certain number of frames to preallocated memory and after this also save the grapped frames to harddrive. Currently it works fine but sometimes I am observing a few framedrops (1-3). When this happens I reset the experiment and repeat the recording and usually i am lucky the second time with no framedrops (the camera-driver has a internal framecounter that I am using). Question: I usually go to tty1 and use "sudo service gdm stop" to disable the graphical frontend. It seems to release some memory though that is not my main concern. My concern is CPU resources. Are there other system hungry modules that can be disabled temporarily such that the CPU gets less busy on Ubuntu 9.10? At some point in the future I will update to 10.10. Should I perhaps option for the server edition instead? Thanks.

• Are there legitimate reasons for returning exception objects instead of throwing them?

  - by stakx

  This question is intended to apply to any OO programming language that supports exception handling; I am using C# for illustrative purposes only. Exceptions are usually intended to be raised when an problem arises that the code cannot immediately handle, and then to be caught in a catch clause in a different location (usually an outer stack frame). Q: Are there any legitimate situations where exceptions are not thrown and caught, but simply returned from a method and then passed around as error objects? This question came up for me because .NET 4's System.IObserver<T>.OnError method suggests just that: exceptions being passed around as error objects. Let's look at another scenario, validation. Let's say I am following conventional wisdom, and that I am therefore distinguishing between an error object type IValidationError and a separate exception type ValidationException that is used to report unexpected errors: partial interface IValidationError { } abstract partial class ValidationException : System.Exception { public abstract IValidationError[] ValidationErrors { get; } } (The System.Component.DataAnnotations namespace does something quite similar.) These types could be employed as follows: partial interface IFoo { } // an immutable type partial interface IFooBuilder // mutable counterpart to prepare instances of above type { bool IsValid(out IValidationError[] validationErrors); // true if no validation error occurs IFoo Build(); // throws ValidationException if !IsValid(…) } Now I am wondering, could I not simplify the above to this: partial class ValidationError : System.Exception { } // = IValidationError + ValidationException partial interface IFoo { } // (unchanged) partial interface IFooBuilder { bool IsValid(out ValidationError[] validationErrors); IFoo Build(); // may throw ValidationError or sth. like AggregateException<ValidationError> } Q: What are the advantages and disadvantages of these two differing approaches?

• For a large website developed in PHP, is it necessary to have a framework?

  - by Martin

  I am wondering if it is necessary to have a framework or if it is a must-have if I plan to make a large website. Large website could mean a lot of things: in other words, multiple dynamic web pages (40-50 dynamic pages, mysql content) and a lot of visitors (+- a million hits per month). The site will be hosted in a dedicated server environment. I know that it could simplify coding for a developer team, that it includes libraries and a lot of advantages. But I just feel that I don't need that. I think that learning how it works, managing it and installing it would take more time and I could use that time to code. I write PHP the simplest way I could (with performance in mind) and I try to reuse my code/functions/classes most of the time and I make sure that if another developer joins the team, that he won't be lost in the code. I am also planning to use MemCached or another Cache for PHP. As I said, the site will be hosted in a dedicated server environment but will be entirely managed by the hosting company. I am pretty sure the control panel for me to control the basic stuff will be Cpanel. For a developer like me that only knows PHP, Javascript, HTML, CSS, MYSQL and really basic server management, I feel that it seems to complicated to have a framework. Am I wrong? Is it worth the time to learn all about it? Thank you for your opinions and suggestions.

• What do I need to Mod a Unreal Engine 3 game?

  - by RoadSideWarrior

  what I am looking for is some advise making a mod for a certain game and how I would go about making it. The game I am talking about is Blacklight: Retribution and what I wan't to know is; Is it possible? And if so, what programs will I need? It is an online only game so I was unsure how plausible a mod would be for it. Plus I have never made a video game before, but I do like the game and I wanted to do some things with it. Additionally, this will be my first time making anything video game related so I would appreciate any advise. To expand a bit, I plan to add something simple at first. A mod that would let you spectate another player in the first person. Then I plan do something a bit more complex where I want to make so the game optionally always records you playing (in short intervals most likely or you would run quickly out of memory). After all that is done I would add items, armor, weapons, and maybe make a map or not I am not sure but this in a shell what I hope to do. I don't know much about these things but I am reading anything I can get my hands on. So if this is overly ambitious or just plain out not a possibility any advise on what I should look to instead will be welcomed warmly. Thank you.

• How do I simplify a 2D game grid for level management while keeping its by-pixel features?

  - by Eric Thoma

  (I cross-posted this from StackOverflow as this seems to be a more appropriate forum. I've looked around a little here and I did not find an answer, so I hope this is not a recurring question.) This is a question dealing with 2D world design. I am playing around by creating a 2D bird's eye view shooter game, and I am looking to make the game sleek and advanced. I hope to be able to write physics so projectiles have momentum and knock-down properties. I am immediately running into the problem of world design. I need a way to have level files that store everything there is about a game. This is easiest by just having a grid of objects. But there are thin-walls and other objects that don't seem to fit into a traditional cell of a grid. I want to be able to fit all these together so I can streamline level design; so I don't have to put in the exact pixel-specific start and end of a wall. There doesn't seem to be an obvious translation from level file to game without forcing myself into a pacman-life scenario, meaning a scenario where the game feels boxy and discrete. There is a contrast between the smoothly (relatively) moving characters and finite jumps in a grid. I would appreciate an answer that would describe implementation options or point me to resources that do. I would also appreciate references to sites that teach game design. The language I am using is Java (although I would love to use C or C++, but I can never find convenient resources in those languages). Thank you for any answers. Please leave any questions in the space below; I will be able to answer them later tonight (28th Nov).
