  • Do I need a degree in Computer Science to get a Jr Programming job in the world? [closed]

    - by t84
    As above really, do I need to go to Uni to get a job as a Junior C# coder? I'm 26 and have been working in Games (Production) for 6 years and I am thinking of a change, I've had exposure to VB6, VBA, HTML, CSS, PHP, JavaScript over the past few years and did a web design NCFE at College, but other than that, nothing else! I'm teaching myself C# at the moment with books and I was wondering 'how much' I need to learn and also how I can improve my chances of getting a programming job! Am I a late started to learn coding? (I know many people who started at a very young age!) Thanks for the help :)

  • cannot use sudo on ubuntu server passwordless authentication?

    - by Lucas Crijns
    Hello I'm new at the forum and I want to introduce myself: I'm Lucas Crijns and I'm a very happy user of ubuntu server. I was reading about passwordless authentication with ssh. So I made a key and published it to ubuntu server, it worked well and I could login with my private key. But then I locked the account to prevent hacking from my password. After I ran "passwd -l lucas", I was not longer able by my next login to use sudo. Because it was asking for a password and I locked it. I was thinking that sudo would also be without a password. My question is now: is it possible to use sudo? And how can I enable it without a valid password for sudo? Thank you for your help!

  • How can an SQL relational database be used to model a thesaurus? [closed]

    - by Miles O'Keefe
    I would like to design a web app that functions as a simple thesaurus: a long list of words with attributes, all of which are linked to each other. This thesaurus data model can be defined as: a controlled vocabulary arranged in a known order in which equivalence, hierarchical, and associative relationships among terms are clearly displayed and identified by standardized relationship indicators. My idea so far is to have one database in which every word is a table, and every table contains all words related to that word. e.g. Thesaurus(database) - happy(table) - excited(row)|cheerful(row)|lively(row) Is there are more efficient way to store words and their relationship to other words in a relational SQL database?

  • Why do I have to choose between "management" and "technical" tracks in my career?

    - by Stephen Gross
    I was recently laid off, and although I found a new gig I'm a bit frustrated with how career tracks work in the land of software development. I really love doing a bit of everything: coding, testing, architect(ing), leadership/management, customer contact, requirements gathering, staff development, etc. Software companies, however, want me to fit into a niche: I'm either a coder, a tester, or a manager. When I try to explain to them that I'm best when I'm doing all of those at once, they seem very confused. I'm sympathetic to their interests, but at the same time frustrated that the industry works this way. Any advice? Do I just need to get with the program, so to speak?

  • How to measure the right time to bring a new client?

    - by Byron Sommardahl
    My growing company has a team of developers working on a number of separate projects. Our developers depend on us to keep them working, and we depend on them to make our clients happy. Our projects have differing start and end dates, as you can imagine. The company's responsibility to the developers is to make sure we have clients waiting in the wings so that when one project ends, another can start. For now, finding clients is not a problem and not the topic of this question. What I'm trying to think through right now is, how can I best measure/view/evaluate the end dates of projects so that I know when I need to start courting the next client. Is there a tool that does this? If it's just a spreadsheet, what might it look like?

  • Transiltion from maintenance programing to design

    - by andrew wang
    What to do guys do develop a design for a s/w for a given set of requirements? I like many people joined a Semiconductor MNC and got stuck in maintenance for quite a couple of years. My work was usually changing a lines of code for windows drivers supplied by my company or a couple of small script (style like) C programs for validating h/w. As a result I developed the bad habit of 'programming by coincidence'. I have not developed the ability for designing tools/programs from scratch. I was the only s/w member of the local team and thus some grunt work from the well established other site of the company came to be done by me. Now I have moved to a different company and thus finding developing from scratch very difficult. How do I unlearn my bad habit and develop this ability of designing s/w and then coding it ?

  • Unity 3d (Using Blender) - anime/manga/cel-shaded style characters

    - by David Archer
    Making a game using Blender for 3D models and Unity for the game engine. Just wondering if anyone knows any links to pages that give a tutorial on Japanese anime style 3D modelling, texturing and shading through blender. I'm actually looking to create a cel-shaded look eventually (read: Okami/Jet Set Radio style) and I'm kind of stuck with the design stuff. I'm not a Blender expert by any means, and still kind of new to the design side of things (I'm a programmer by trade), so please don't vote me down too hard. I've tried googling, but there doesn't seem to be much in the way of what I'm after. The only thing I've found really is a plugin for blender called freestyle, or using the ToonShader shading tool. If there are any good tutorials or anything, I'm really happy to sit through them - just want to learn :) Thanks for any help :)

  • Is Morton Code algorithm patented?

    - by Statement
    Synonyms: Morton Code, Morton Curve, Z-Order Curve, invented 1966 by G. M. Morton according to wiki. Not to be confused with Hilbert Curves which is closely related and have similar name. I was wondering if mentioned algorithm is patented. More generally, is there any place one can browse patented algorithms? I am quite new to all this legal stuff and I am keen to know more. The real question I have, I guess, is: Can I make money off a library that provides Morton Coding, legally?

  • Friday Spotlight - October 25, 2013

    - by Chris Kawalek
    Happy Friday, everyone! Our spotlight this week is on a really cool technical tip on the Oracle Technology Network from Yuli Vasiliev called "How to Launch Linux Utilities from Oracle Database". From Yuli's introduction: "By wrapping a Linux utility in a script and using an external database table's preprocessor directive, you can launch the utility from within Oracle Database and have the utility's output be inserted into the external table. This allows you to do things such as query operating system data and then join it with data in Oracle Database." Head on over to OTN to read the full article. -Chris

  • Ubuntu upgrade deleted my email accounts

    - by Johnt
    I'm a long term Ubuntu user and until today I have been really happy. I've always run Evolution and Thunderbird and after Ubuntu apparently upgraded me from 11.04 to 11.10 both my Evolution and Thunderbird programmes and all data / address books, messages and folders were deleted and I now have to create new accounts for both programmes. All my previous data is LOST. Thanks a lot guys. Why did this happen and why was there no warning given that this could be an issue ??? Is any of this recoverable ?

  • Adding an LOV to a query parameter (executeWithParams)

    - by shay.shmeltzer
    I showed in the past how you can use the executeWithParams operation to build your own query page to filter a view object to show specific rows. I also showed how you can make the parameter fields display as drop down lists of values (selectOneChoice). However this week someone asked me if you can have those parameter fields use the advanced LOV component. Well if you just try and drag the parameter over, you'll see that the LOV option is not there as a drop option. But with a little bit of hacking around you can achieve this. (without actual Java coding). Here is a quick demo:

  • DBMS agnostic - What to name the COUNT column from a SQL Query

    - by cyberkiwi
    I have trouble naming the COUNT() column from SQL queries and will swap between various variants _Count [Count] (sql, or "count" or backticks for MySQL etc) C Cnt CountSomething (where "something" is the field being counted, or "CountAll") NoOfRows RowCount etc Has anyone come up with any name that you are happy with and always use without hesitation? This is bothering me because after joining SO just recently, my answers have shown this tendency of flip-flopping with no consistency. I need to get this sorted. Please help. (While we're at it, what do you use for SUM etc?) Note: Before you close this question, consider that this one was not: What's the best name for a non-mutating “add” method on an immutable collection?

  • Why is C++ predominant in programming contests and competitions?

    - by daniels
    I understand that C++ is a very fast language, but ain't C just as fast, or faster in some cases? Then you might say that C++ has OOP, but the amount of OOP you need for most programming puzzles is not that big, and in my opinion C would be able handle that. Here's why I am asking this: I am very interested in programming contests and competitions, and I am used to coding in C on those. However, I noticed that the vast majority of people use C++ (e.g., 17 out of 25 finalists on Google Code Jam 2011 used it, while no one used C), so I am wondering if I am at a disadvantage going with C. Apart from the Object Orientation, what makes C++ a more suitable language for programming competitions? What are the features of the language I should learn and use to perform better on the competitions? For background, I consider myself pretty proficient in C, but I am just starting to learn C++.

  • Oracle Keeps Growing Partner Certifications with Addition of McAfee

    - by Ted Davis
    Viruses stink. Whether it’s the common cold virus, Goatpox virus – yes it exists -- or a computer virus, you name it, viruses stink. When it comes to our computer server infrastructure we all want to make sure our servers are secure from any malware out there. Additionally, installation of anti-virus software is a requirement by many governments and for many enterprises both large and small. Because of the growth of Oracle Linux in their customer base, McAfee recently certified their “McAfee VirusScan Enterprise for Linux” on Oracle Linux.  It delivers always-on, real-time anti-virus protection for Linux environments. Its unique, Linux-based on-access scanner constantly monitors the system for potential attacks. While there have been few viruses found on Linux, you can now feel secure running Oracle Linux in your infrastructure with McAfee on top. We are happy to introduce McAfee into the Oracle Linux family of certified applications.

  • New to Ubuntu - 12.04.1 Kernel Panic on Installation

    - by user88432
    I'm a complete Ubuntu and even Linux newbie. I'm learning here, so I'm grateful for any info to help me learn more about this. I have a Dell Dimension 2400 with a Pentium 4 and 1GB of RAM. It's older but it's only going to be doing some small stuff for me when I get it up and going. I've tried installing several versions of Linux (but I really, really want Ubuntu) and I keep getting a similar kernel panic message. The problem is I don't have a clue what that means or how to begin fixing it. I would appreciate any help to get my machine up and going. I have already tried Installing alternate Ubuntu versions Burning multiple 12.04.1 disks Installing other versions of Linux I have a picture of the screen to share; however, I can't post due to the fact that I don't have enough reputation points on this forum because I'm a newbie. I would be happy to email you a pic, if you think you can help.

    - by t3st
    I have a website which i want to make more mobile friendly(currently its not). While searching about this i found this awesome website Ginwiz; my website can be modified into an mobile friendly site without any additional coding. But i find two disadvantages with this website (free version) 1)We cant add our domain to it with out upgrading (i dont have enough money to pay for it) 2)We can only "Advanced edit" one page Do you know any website which is similar to Ginwiz but can use our domain address instead of theirs (in free version). Do you have any idea about any tools which can be also used to convert my website to mobile website by trimming my current website easily.

  • Type dependencies vs directory structure

    - by paul
    Something I've been wondering about recently is how to organize types in directories/namespaces w.r.t. their dependencies. One method I've seen, which I believe is the recommendation for both Haskell and .NET (though I can't find the references for this at the moment), is: Type Type/ATypeThatUsesType Type/AnotherTypeThatUsesType My natural inclination, however, is to do the opposite: Type Type/ATypeUponWhichTypeDepends Type/AnotherTypeUponWhichTypeDepends Questions: Is my inclination bass-ackwards? Are there any major benefits/pitfalls of one over the other? Is it just something that depends on the application, e.g. whether you're building a library vs doing normal coding?

  • 2D basic map system

    - by Cyril
    i'm currently coding a 2D game in Java, and I would like to have some clues on how-to build this system : the screen is moving on a grander map, for instance, the screen represent 800*600 units on a 100K*100K map. When you command your unit to go to another position, the screen move on this map AND when you move your mouse on a side or another of the screen, you move the screen on the map. Not sure that i'm clear, but we can retrieve this system in most RTS games (warcraft/starcraft for example). I'm currently using Slick 2D. Any idea ? Thanks.

  • Thought Oracle Usability Advisory Board Was Stuffy? Wrong. Justification for Attending OUAB: ROI

    - by ultan o'broin
    Looking for reasons tell your boss why your organization needs to join the Oracle Usability Advisory Board or why you need approval to attend one of its meetings (see the requirements)? Try phrases such as "Continued Return on Investment (ROI)", "Increased Productivity" or "Happy Workers". With OUAB your participation is about realizing and sustaining ROI across the entire applications life-cycle from input to designs to implementation choices and integration, usage and performance and on measuring and improving the onboarding and support experience. If you think this is a boring meeting of middle-aged people sitting around moaning about customizing desktop forms and why the BlackBerry is here to stay, think again! How about this for a rich agenda, all designed to engage the audience in a thought-provoking and feedback-illiciting day of swirling interactions, contextual usage, global delivery, mobility, consumerizationm, gamification and tailoring your implementation to reflect real users doing real work in real environments.  Foldable, rollable ereader devices provide a newspaper-like UK for electronic news. Or a way to wrap silicon chips, perhaps. Explored at the OUAB Europe Meeting (photograph from Terrace Restaurant in TVP. Nom.) At the 7 December 2012 OUAB Europe meeting in Oracle Thames Valley Park, UK, Oracle partners and customers stepped up to the mic and PPT decks with a range of facts and examples to astound any UX conference C-level sceptic. Over the course of the day we covered much ground, but it was all related in a contextual, flexibile, simplication, engagement way aout delivering results for business: that means solving problems. This means being about the user and their tasks and how to make design and technology transforms work into a productive activity that users and bean counters will be excited by. The sessions really gelled for me: 1. Mobile design patterns and the powerful propositions for customers and partners offered by using the design guidance with Oracle ADF Mobile. Customers' and partners' developers existing ADF developers are now productive, efficient ADF Mobile developers applying proven UX guidance using ADF Mobile components and other Oracle Fusion Middleware in the development toolkit. You can find the Mobile UX Design Patterns and Guidance on Building Mobile Apps on OTN. 2. Oracle Voice and Apps. How this medium offers so much potentual in the enterprise and offers a window in Fusion Apps cloud webservices, Oracle RightNow NLP and Nuance technology. Exciting stuff, demoed live on a mobile phone. Stay tuned for more features and modalities and how you can tailor your own apps experience.  3. Oracle RightNow Natural Language Processing (NLP) Virtual Assistant technology (Ella): how contextual intervention and learning from users sessions delivers a great personalized UX for users interacting with Ella, a fifth generation VA to solve problems and seek knowledge. 4. BYOD Keynote: A balanced keynote address contrasting Fujitsu's explaining of the conceprt, challenges, and trends and setting the expectation that BYOD must be embraced in a flexible way,  with the resolute, crafted high security enterprise requirements that nuancing the BYOD concept and proposals with the realities of their world of water tight information and device sharing policies. Fascinating stuff, as well providing anecdotes to make us thing about out own DYOD Deployments. One size does not fit all. 5. Icon Cultural Surveys Results and Insights Arising: Ever wondered about the cultural appropriateness of icons used in software UIs and how these icons assessed for global use? Or considered that social media "Like" icons might be  unacceptable hand gestures in culture or enterprise? Or do the old world icons like Save floppy disk icons still find acceptable? Well the survey results told you. Challenges must be tested, over time, and context of use is critical now, including external factors such as the internet and social media adoption. Indeed the fears about global rejection of the face and hand icons was not borne out, and some of the more anachronistic icons (checkbooks, microphones, real-to-real tape decks, 3.5" floppies for "save") have become accepted metaphors for current actions. More importantly the findings brought into focus the reason for OUAB - engage with and illicit feedback though working groups before we build anything. 6. EReaders and Oracle iBook: What is the uptake and trends of ereaders? And how about a demo of an iBook with enterprise apps content?  Well received by the audience, the session included a live running poll of ereader usage. 7. Gamification Design Jam: Fun, hands on event for teams of Oracle staff, partners and customers, actually building gamified flows, a practice that can be applied right away by customers and partners.  8. UX Direct: A new offering of usability best practices, coming to an external website for you in 2013. FInd a real user, observe their tasks, design and approve, build and measure. Simple stuff to improve apps implications no end. 9. FUSE (an internal term only, basically Fusion Simplified Experience): demo of the new Face of Fusion Applications: inherently mobile, simple to use, social, personalizable and FAST, three great demos from the HCM, CRM and ICT world on how these UX designs can be used in different ways. So, a powerful breadth and depth of UX solutions and opporunities for customers and partners to engage with and explore how they can make their users happy and benefit their business reaping continued ROI from those apps investments.

  • How can I reduce lagging with GUI/GPU stuff -- make Unity run smaller, quicker, faster?

    - by chris
    Finally installed Ubuntu 12.04 on my HP Pavilion 2000. Have all of my apps on and loaded and am happy thus far. ONE ISSUE -- I'm experiencing a small amount of GUI/GPU style lagging when I go to open menus, move windows, etc. What settings can I disable to allow it to run sharply and quickly, even if i t means sacrificing some of the graphics? Have already installed pre-load. Just want the OS to run sharply and quickly with menu refreshes, window moves, etc. I do not mind sacrificing graphics. Somone mentionted to me I have to install video drivers but the two that come up in system settings under drivers it won't let me install. ALSO : I am driving a second 19" monitor -- would that make a difference performance wise as well? Thanks in advance. Chris

  • JDeveloper and Upgrading Your JDK on Ubuntu

    - by Duncan Mills
    One little gotcha, if you, as I did recently, upgrade your JDK on Ubuntu then you may have to make sure you reflect that change in a couple of places for JDeveloper to stay happy. Assuming that you've installed from the jar version of the JDeveloper installer, then the JDK that you specified at install time will be recorded in the .jdev_jdk file in your home directory.However, be aware that this is not the only reference to the absolute path of the JDK. When you run the embedded WebLogic for the first time then the .jdeveloper/system11.1.1.3.37.56.60/DefaultDomain/bin/startWebLogic.shscript will be created, and associated with that, the setDomainEnv.sh script in the same directory. So, if you do want to change the JDK location be sure to change this file as well. (or of course do everything with symbolic links)
