  • Web Development know how. Best practices [closed]

    - by Mir
    Possible Duplicate: What should every programmer know about web development? I have recently started learning about web development and I am currently working on a project that involves web scraping. While doing the project I came across an error which upon doing a little web search made me realize that one must clean the html before processing it further. Similarly, there were a few more interesting things that I had missed. My question is how can I quickly familiarize myself with best practice methods for web development.( I am asking as an an electrical engineer with experience in C/C++/Java and very little experience in web dev). Thanks

  • What PC for programming? [on hold]

    - by James Jeffery
    I'm asking this here because I'm looking for some advice on a PC that will be suitable for my needs. I currently have mac's and have rarely used PC's apart from my Vaio laptop, which is on it's way out. I will be using the PC for C# and .NET development. I mainly develop desktop apps using a PC, but I will be doing some ASP.NET as I'm switching from PHP to ASP. The selection of PC's are on here: http://www.pcworld.co.uk/ I have £500, but if I can not spend all of that I'd be happy. I will be doing nothing on the computer apart from C# development (desktop and ASP). Any help would be much appreciated. My applications are not intensive. They are usually automation software for web scraping and marketing purposes.

  • How do I make good guy attacks only hit bad guys and vice versa?

    - by tieTYT
    My game has many different type of good guys and many different type of bad guys. They will all be firing projectiles at each other but I don't want any accidental collateral damage to occur for either alignment. So bad guys should not be able to hit/damage other bad guys and good guys should not be able to hit/damage other good guys. The way I'm thinking of solving this is by making it so that the Unit instance (this is javascript, btw), has an alignment property that can be either good or bad. And I'll only let collision happen if the class Attack boolean didAttackCollideWithTarget(target) return attack.source.alignment != target.alignment and collisionDetected(attack.source, target) This is pseudo-code, of course. But I'm asking this question because I get the sense that there might be a much more elegant way to design this besides adding yet another property to my Unit class.

  • Searching for the J. R. "Bob" Dobbs screensaver from Slackware to install in 13.10

    - by kiloseven
    I have seen on older (ca. 2004) RHEL systems a screensaver, xlock, with a twisting and morphing picture of J. R. "Bob" Dobbs. An extensive search of screensavers available for Ubuntu has not provided revelation. Does any SubGenius out there know where I may find it for the current Lubuntu ver. 13.10? Thank you kindly. Where do I expect to find it? Well, every screensaver app available via Synaptic and Ubuntu Software Center has been checked, to no avail. I have also done an extensive search for it via multiple search engines, not merely looking at the first screen in a Google Search. That's why I am asking here. How might I import that app from Slackware's repository into Lubuntu?

  • c++ write own xml parser vs using tinyxml

    - by AdityaGameProgrammer
    Hi , I am currently in a task to generate an XML file for an srt text file containing timestamps and corresponding text. To generate an exe file which accepts file name input and outputs the relevant XML file to be used as part of an automated script. Is it Advisable to use Tinyxml for this? Is this a very simple task that can be done with minimal programming? Is this one of those things which are very basic to c++ programmers? reason i am asking this is I have recently made a shift into c++ programming after over 3 years of action script development. Edit: your comments regarding this are very much appreciated what's the easiest way to generate xml in c++?

  • What’s the opposite of abstraction?

    - by Ollie Saunders
    As I understand it, abstraction is the term we use for when more meaning is created out of something simpler without altering it. It is derived from the latin verb abstrahere (to ‘draw away’). For instance, text is just one abstraction of binary data—as are bitmaps. So, in computers, text and bitmaps exist on top of (are implemented in terms of) binary data. My question is: what is the opposite term? If I want to know the possible more basic things that bitmaps could be implemented in terms of other than binary data—things like tiles for a mosaic or fabric patches for a patchwork quilt—what am I asking for? Is there a word for that? Abstraction has connotations of generalization and the opposite process of that is specialization. IDK whether that helps.

  • Ubuntu no longer prompts for root privilege (but doesn't give it either)

    - by Elad Avron
    So on 14.04 LTS I was playing around with some settings to solve another problem, and somehow managed to screw things up and now Ubuntu no longer asks for root privileges before trying to perform administrative actions. The catch is that my user does NOT have them by default, which means those actions ALL fail. I can still run "sudo " from terminal and it'll ask for my password and work fine, but any GUI that requires root just fails without asking anything. Any ideas what I did wrong and how to solve it? Thanks in advance.

  • Wireless driver - how to load manufacturer's STA file (Ralink 3290)

    - by Matt
    Caution: I'm a newb. Hardware: Giada i35G, cedar trail atom with nvidia gf119, railtek ethernet and Ralink 3290 for wireless. Already accomplished: Installed Ubuntu 12.10, loaded GPU drivers and redirected sound out through GPU card to HDMI. Ethernet works like a charm. Issue: Can't get my wireless up and running. There seems to be no package to which I can simply run a sudo get-aspt install ... I found the corresponding Linux driver from the manufacturer's site, but I have not managed to find out what to with the file. Here's the manufacturers site: http://www.ralinktech.com/en/04_support/support.php?sn=501 I get a file with the following name: \2012_0508_RT3290_Linux_STA_v2.6.0.0.bz2 I hope somebody might be able to tell me what to do next. Thanks for reading and apologies for potentially asking a trivial question. Best regards, Matt

  • visual basic coach needed [closed]

    - by Danny
    0 down vote favorite I am trying to learn visual basic. I used to program in gw-basic and have trouble learning vb.net by reading and googling all the time. It takes so much time to find the answers to my programming problems and even then i do not understand the why it have to be done that way. I have beginners questions like finding childwindows using enumwindow. Then googling for hours and hours i do not seem to grasp it (must be my old age). I would like to get someone i could learn from by asking questions about what i want to program and learn from it. not to just finish the program but to learn and understand it too. Someone who dont find questions stupid to ask as i try to build my understanding of the visual basic environment. I hope to communicate by using skype voice or chat or other direct means when time permits it. Cheers, Danny

  • Where to go after Adobe Flex? [closed]

    - by jan halfar
    After this post http://blogs.adobe.com/flex/2011/11/your-questions-about-flex.html and especially this paragraph: ... Does Adobe recommend we use Flex or HTML5 for our enterprise application development? In the long-term, we believe HTML5 will be the best technology for enterprise application development. We also know that, currently, Flex has clear benefits for large-scale client projects typically associated with desktop application profiles. ... Make no mistake, the days of Flex are over. Thus a lot of people are asking themselves: Which technology(ies) will solve their and their customers problems in a future without flex? P.S.: Obviously the correct answer for adobe would have been " ...Since we believe, that HTML5 will be the best technology enterprise application development, we will ensure that it will be targeted by future releases of the Flex framework ..."

    Every year there are different types of freshers getting recruited. But, our IT field is not only limited to IT Engineers & Computer Engineers. It is full of all different types of engineers. What is a way an engineer can be a proper developer ? I am asking this because, whatever engineering the student gone for, one can be shifted to IT development if he/she has some particular qualities within. What are those quelities required to be in a developer or required to be implemented to be developer ?

  • Can we replace XML with JSON entirely?

    - by Saeed Neamati
    I'm sure lots of developers are familiar with XML and JSON, and they've used both of them. Thus no point in explaining what they are, and what is their purpose, even in brief. If we try to map their concepts, we can say (correct me if I'm wrong): XML tags are equivalent to JSON {} XML attributes are equivalent to JSON properties XML tag collection is equivalent to JSON [] The only thing I can think of, which doesn't exist in JSON, is XML Namespaces. The question is, considering this mapping, and considering that JSON is highly lighter in this mapping, can we see a world in future (or at least theoretically think of a world) without XML, but with JSON doing everything XML does? Can we use JSON everywhere XML is used? PS: Please note that I've seen this question. It's something entirely different from what I'm asking here. Thus please don't mention duplicate.

  • Storing large data in HTTP Session (Java Application)

    - by Umesh Awasthi
    I am asking this question in continuation with http-session-or-database-approach. I am planning to follow this approach. When user add product to cart, create a Cart Model, add items to cart and save to DB. Convert Cart model to cart data and save it to HTTP session. Any update/ edit update underlying cart in DB and update data snap shot in Session. When user click on view cart page, just pick cart data from Session and display to customer. I have following queries regarding HTTP Session How good is it to store large data (Shopping Cart) in Session? How scalable this approach can be ? (With respect to Session) Won't my application going to eat and demand a lot of memory? Is my approach is fine or do i need to consider other points while designing this? Though, we can control what all cart data should be stored in the Session, but still we need to have certain information in cart data being stored in session?

  • Ubuntu CD Boots to Black Screen

    - by Thomas
    I have a new Asus N76 Notebook and just downloaded the lastest ubuntu 12.10 desktop CD (x64). When I boot from the CD, I get to the selection asking to try or install Ubuntu (the text screen not the one with the Ubuntu logo). When I select one of these options, I get only a black screen. I have tried nomodeset, acpi=off but it does not change anything. I also tried booting a CD and an USB stick (same result). I have no idea what to try next. I have installed Ubuntu on several computers yet, never had this problem. Any suggestions? Thanks in advance. Thomas

  • What Did You Do? is a Bad Question

    - by Ajarn Mark Caldwell
    Brian Moran (blog | Twitter) did a great presentation today for the PASS Professional Development Virtual Chapter on The Art of Questions.  One of the points that Brian made was that there are good questions and bad (or at least not-as-good) questions.  Good questions tend to open-up the conversation and engender positive reactions (perhaps even trust and respect) between the participants; and bad questions tend to close-down a conversation either through the narrow list of possible responses (e.g. strictly Yes/No) or through the negative reactions they can produce.  And this explains why I so frequently had problems troubleshooting real-time problems with users in the past.  I’ll explain that in more detail below, but before we go on, let me recommend that you watch the recording of Brian’s presentation to learn why the question Why is often problematic in the U.S. and yet we so often resort to it. For a short portion (3 years) of my career, I taught basic computer skills and Office applications in an adult vocational school, and this gave me ample opportunity to do live troubleshooting of user challenges with computers.  And like many people who ended up in computer related jobs, I also have had numerous times where I was called upon by less computer-savvy individuals to help them with some challenge they were having, whether it was part of my job or not.  One of the things that I noticed, especially during my time as a teacher, was that when I was helping somebody, typically the first question I would ask them was, “What did you do?”  This seemed to me like a good way to start my detective work trying to figure out what happened, what went wrong, how to fix it, and how to help the person avoid it again in the future.  I always asked it in a polite tone of voice as I was just trying to gather the facts before diving in deeper.  However; 99.999% of the time, I always got the same answer, “Nothing!”  For a long time this frustrated me because (remember I’m in detective mode at that point) I knew it could not possibly be true.  They HAD to have done SOMETHING…just tell me what were the last actions you took before this problem presented itself.  But no, they always stuck with “Nothing”.  At which point, with frustration growing, and not a little bit of disdain for their lack of helpfulness, I would usually ask them to move aside while I took over their machine and got them out of whatever they had gotten themselves into.  After a while I just grew used to the fact that this was the answer I would usually receive, but I always kept asking because for the .001% of the people who would actually tell me, I could then help them understand what went wrong and how to avoid it in the future. Now, after hearing Brian’s talk, I understand what the problem was.  Even though I meant to just be in an information gathering mode, the words I was using, “What did YOU do?” have such a strong negative connotation that people would instinctively go into defense-mode and stop sharing information that might make them look bad.  Many of them probably were not even consciously aware that they had gone on the defensive, but the self-preservation instinct, especially self-preservation of the ego, is so strong that people would end up there without even realizing it. So, if “What did you do” is a bad question, what would have been better?  Well, one suggestion that Brian makes in his talk is something along the lines of, “Can you tell me what led up to this?” or “what was happening on the computer right before this came up?”  It’s subtle, but the point is to take the focus off of the person and their behavior; instead depersonalizing it and talk about events from more of a 3rd-party observer point of view.  With this approach, people will be more likely to talk about what the computer did and what they did in response to it without feeling the interrogation spotlight is on them.  They are also more likely to mention other events that occurred around the same time that may or may not be related, but which could certainly help you troubleshoot a larger problem if it is not just user actions.  And that is the ultimate goal of your asking the questions.  So yes, it does matter how you ask the question; and there are such things as good questions and bad questions.  Excellent topic Brian!  Thanks for getting the thinking gears churning! (Cross-posted to the Professional Development Virtual Chapter blog.)

  • PHP Development Environment (Host: Windows 7, Guest: Ubuntu)

    - by Kristian Leiws Jones
    Since editing files live from a remote server slows down development. I use XAMPP on windows to develop then run the web app's on a Linux server. However to avoid environment dependencies I'd like to mirror the live environment and the development environments. What I'm asking is running development server on Ubuntu inside VirtualBox whilst editing the source files via ftp/Dreamweaver is a good idea? If so, and I wanted to view the local website on the host OS (windows) how would I do this? does the guest OS have a LAN/Local IP address? I notice on windows "ipconfig /all" there are "tunneling" adapters which I assume is for VirtualBox, so I guess the guest OS has the same LAN/Local IP address? if so how would I view the websites hosted on the guest OS on the host OS? I'd also need to host FTP server on guest OS. Note: I need windows! I would love to use Linux all the way -.-

  • A few meta questions about making flash games

    - by idan
    A few questions for a beginner game maker without an artist. Is there a site where flash game creators can download (and use) free art? I don't need character sprites but environments like trees, clouds, platforms, etc. Is there a site where a programmer can collaborate with an artist and a composer? (Even if so, the chances are low for a beginner with no portfolio to find an artist willing to collaborate, right?) Do you have recommended sites for asking action script questions (dedicated solely to flash?) Thanks!

  • How can I store spell & items using a std::vector implementation?

    - by Vladimir Marenus
    I'm following along with a book from GameInstitute right now, and it's asking me to: Allow the player to buy and carry healing potions and potions of fireball. You can add an Item array (after you define the item class) to the Player class for storing them, or use a std::vector to store them. I think I would like to use the std::vector implementation, because that seems to confuse me less than making an item class, but I am unsure how to do so. I've heard from many people that vectors are great ways to store dynamic values (such as items, weapons, etc), but I've not seen it used.
