  • Are Web Safe Colors Still Relevant?

    - by VxJasonxV
    I still remember one of my high school teachers lecturing us about the "web safe colors". A set of 216-256 colors that you should confine your designs to use, and nothing else besides them. Last I knew, Photoshop still has the "web safe" yield icon[1] on it's color picker. Are web safe colors still a concern? Outside of the obvious application (accessibility, legacy software versions, etc.), how much consideration should I give to limiting my color choice for my general audience? [1] Or was it the cube? I never remember.

  • GRUB install error

    - by Rohit
    Whenever I try to install Ubuntu, I get a fatal error that reads: 'Executing'grub-install /dev/sda' failed. This is a fatal error.' Its the same as this, but my graphics appear to be running fine. Also, I'm a complete novice at this and really need simple instructions to understand what I'm doing. I've tried booting from a LiveCD and a USB stick. I don't want to dual boot it because its an old computer that I erased XP and plan on only using Linux on it. When I used a USB stick and set the persistent file storage high, I was able to run it, but only as long as the flash drive was plugged in.

  • Ubuntu Surround Sound Help?

    - by Adam
    I am running Ubuntu 12.10 on a Sony Vaio VGC-RB34G ( http://reviews.cnet.com/desktops/sony-vaio-vgc-rb34g/4505-3118_7-31289053.html ) with an integrated Realtek High Definition Audio sound card. On Windows, I can set up the sound card to provide sound to my surround sound system from the Line Out, Line In, and Mic ports, as in all of these are producing audio. I have tried to use alsa to achieve this result with no luck. Is there any possible way to do this on Ubuntu? Thanks! Here is a Picture of the manager I have on Windows and the result I want to achieve https://picasaweb.google.com/106733704390489891165/November102012#5809378929755566722

  • How can I explain object-oriented programming to someone who's only coded in Fortran 77?

    - by Zonedabone
    My mother did her college thesis in Fortran, and now (over a decade later) needs to learn c++ for fluids simulations. She is able to understand all of the procedural programming, but no matter how hard I try to explain objects to her, it doesn't stick. (I do a lot of work with Java, so I know how objects work) I think I might be explaining it in too high-level ways, so it isn't really making sense to someone who's never worked with them at all and grew up in the age of purely procedural programming. Is there any simple way I can explain them to her that will help her understand?

  • After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

    - by Ryan P.
    Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

  • To be or not to be: a solutions architech [closed]

    - by jQwierdy
    short version: as a student taking a summer internship, whats more useful for later in my career, taking a job as a solutions Architect, or a software engineer? Long version: I'm a CS major in my 3rd year, I've interviewed with some of the big companies and did not get job offers year (Morgan Stanley, Microsoft, FacebooK) but did receive offers from a startup. I actually got two offers from the same start up. I really like the startup and despite the (much) lower wage at it compared to a bigger company, I could do solutions architecture. Solutions architects (I think) work more on figuring out high level solutions directly for clients, so I'd be working often with a sales team and developers. Everyone knows what (generally) a software engineer does. And so my question is this: for my career, what would be more beneficial to a) know how to do, and b) have on my resume.

  • Sound issue in Lubuntu

    I'm recently having a problem in my Lubuntu deskptop: sound through the speakers doesn't seem to work. The funny thing is: it works when I plug in my earphones.

  • Is Carnegie Mellon (CMU) a Javaschool? Are any prominent universities in the US javaschools? [on hold]

    - by user106149
    I'm guessing CMU would teach C and other unmanaged languages (their course listing shows Principles of Functional Programming as a required course for a BSCS), but it's hard to tell from course listings. I'm looking into applying there, where I have an OK chance of getting in , as well as some other mid-to high tier CS schools. I'm wondering how you can tell if a school mainly teaches Java or goes into C/C++. Everyone says (and I agree, from my current programming knowledge) that learning Java in college exclusively is a bad idea, so I'm hoping to avoid ending up at a 'Javaschool.'

  • Becoming an expert vs boredom [closed]

    - by QAH
    I am a college student, and I love to program, period. I code all kinds of things in different kinds of languages. Although I enjoy programming, I have an extremely hard time sticking to one project for a long time. I attribute this shortcoming to my high level of curiosity, exploring different technologies, languages, libraries, etc. What would be best? Should I settle down more and spend time on becoming an expert in one or two programming fields, or should I be more of a jack of all trades, trying out all kinds of new technologies, languages, programming methods, etc.? I'm guessing that somewhere in the middle would be best. I'm always amazed at how many developers are able to create one or two projects, and develop on them for years. What techniques do you guys employ to help you stay focused on a project?

  • Is software support an option for your career?

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 If you have a technical background, why should you choose a career in support? We have invited Serban to answer these questions and to give us an overview of one of the biggest technical teams in Oracle Romania. He’s been with Oracle for 7 years leading the local PeopleSoft Financials & Supply Chain Support team. Back in 2013 Serban started building a new support team in Romania – Fusion HCM. His current focus is building a strong support team for Fusion HCM, latest solution for Business HR Professionals from Oracle. The solution is offered both on Premise (customer site installation) but more important as a Cloud offering – SaaS.  So, why should a technical person choose Software Support over other technical areas?  “I think it is mainly because of the high level of technical skills required to provide the best technical solutions to our customers. Oracle Software Support covers complex solutions going from Database or Middleware to a vast area of business applications (basically covering any needs that a large enterprise may have). Working with such software requires very strong skills both technical and functional for the different areas, going from Finance, Supply Chain Management, Manufacturing, Sales to other very specific business processes. Our customers are large enterprises that already have a support layer inside their organization and therefore the Oracle Technical Support Engineers are working with highly specialized staff (DBA’s, System/Application Admins, Implementation Consultants). This is a very important aspect for our engineers because they need to be highly skilled to match our customer’s specialist’s expectations”.  What’s the career path in your team? “Technical Analysts joining our teams have a clear growth path. The main focus is to become a master of the product they will support. I think one need 1 or 2 years to reach a good level of understanding the product and delivering optimal solutions because of the complexity of our products. At a later stage, engineers can choose their professional development areas based on the business needs and preferences and then further grow towards as technical expert or a management role. We have analysts that have more than 15 years of technical expertise and they still learn and grow in technical area. Important fact is, due to the expansion of the Romanian Software support center, there are various management opportunities. So, if you want to leverage your experience and if you want to have people management responsibilities Oracle Software Support is the place to be!”  Our last question to Serban was about the benefits of being part of Oracle Software Support. Here is what he said: “We believe that Oracle delivers “State of the art” Support level to our customers. This is not possible without high investment in our staff. We commit from the start to support any technical analyst that joins us (being junior or very senior) with any training needs they have for their job. We have various technical trainings as well as soft-skills trainings required for a customer facing professional to be successful in his role. Last but not least, we’re aiming to make Oracle Romania SW Support a global center of excellence which means we’re investing a lot in our employees.”  If you’re looking for a job where you can combine your strong technical skills with customer interaction Oracle Software Support is the place to be!

  • Free Website Content - Do Articles From Directories Work Anymore? Part 2

    A clever strategy for many SEO experts is to study a site that is ranked highly and then try to copy what those sites do to get so successful. Take a close look at highly ranked sites and you will notice that virtually all of them have a very high number of links pointing to other sites. Let me give an example of a site that is ranked very highly and is exclusively made up of links pointing to other sites, billions of them in fact. I am talking about a site that receives over 100 million hits daily. Learn their secrets in this article.

  • I'm a beginner Java programmer but I want to be useful

    - by user105418
    Programming has always interested me, but after learning some of the basics of Java(I'm talking high school level), I don't really know what to do from there. I want to be able to apply what I learned in some way, whether it be a volunteer project or something, but I probably don't know enough programming. Is it possible for a novice Java programmer to be useful in some way whatsoever. I want to do this because I feel like I could learn more about programming by helping people in theirs, but I'm not sure if I'm even able to this though. Does anyone have any suggestions on how I can contribute to other people's project in some way or how to apply it in some way?

  • Independent sound device for headphones

    I have an Asus K52Jc and in sound configuration there is no independent sound device for the headphones, and so there's no way to have independent volume for speakers and headphones.

  • job offer in dead technology

    - by bold
    I have a job offer in a dead technology (specific programming language) that I don't want to work with nor do I believe it will offer many jobs in the future. It requires twice a year travels abroad, which not a plus in my eyes. On the other hand the money on the table is high. What would you do? edit: as its not clear I got a job in a programming language that is different from the academic programming language I worked with. Now I see it as a mistake to head to that direction.

  • Answers to Conference Revenue Tweet Questions

    - by D'Arcy Lussier
    Originally posted on: http://geekswithblogs.net/dlussier/archive/2014/05/27/156612.aspxI tweeted this the other day… …and I had some people tweet back questioning/asking about the profit number. So here’s how I came to that figure. Total Revenue Let’s talk total revenue first. This conference has a huge list of companies/organizations paying some amount for sponsorship. Platinum ($1500) x 5 = $7500 Gold ($1000) x 3 = $3000 Silver ($500) x 9 = $4500 Bronze ($250) x 13 = $3250 There’s also a title sponsor level but there’s no mention of how much that is…more than $1500 though, so let’s just say $2500. Total Sponsorship Revenue: $20750.00 For registrations, this conference is claiming over 300 attendees. We’ll just calculate at 300 and the discounted “member rate” – $249. Total Registration Revenue: $74700.00 Booth space is also sold for a vendor area, but let’s just leave that out of the calculation. Total Event Revenue: $95450.00 Now that we know how much money we’re playing with, let’s knock out the costs for the event. Total Costs Hard Costs Audio/Visual Services $2000 Conference Rooms (4 Breakouts + Plenary) $2500 Insurance $700 Printing/Signage $1500 Travel/Hotel Rooms $2000 Keynotes $2000 So let’s talk about these hard costs first. First you may be asking about the Audio Visual. Yes those services can be that high, actually higher. But since there’s an A/V company touted as the official A/V provider, I gotta think there’s some discount for being branded as such. Conference rooms are actually an inflated amount of $500 per. Venues make money on the food they sell at events, not on room rentals. The more food, the cheaper the rooms tend to be offered at. Still, for the sake of argument, let’s set the rooms at $500 each knowing that they could be lower. For travel and hotel rooms…it appears that most of the speakers at this conference are local, meaning there’s no travel or hotel cost. But a few of them I wasn’t too sure…so let’s factor in enough to cover two outside speakers (airfare and hotel). There are two keynotes for this event and depending on the event those may be paid gigs. I’m not sure if they are or not, but considering the closing one is a comedian I’m going to add some funds here for that just in case. Total Hard Costs: $10700 Now that the hard costs are out of the way, let’s talk about the food costs. Food Costs The conference is providing a continental breakfast (YEEEESH!), some level of luncheon, and I have to assume coffee breaks in between. Let’s look at those costs. Continental Breakfast $12 per person Lunch Buffet $18 per person Coffee Breaks (2) $6 per person (or $3 a cup) Snacks (2) $10 per person (or $5 each) Note that the lunch buffet assumes a *good* lunch buffet – two entrees, starch, vegetable, salads, and bread. Not sure if there’ll be snacks during coffee breaks but let’s assume so. Total Food Cost Per Person: $46 Food Cost: $14950 Gratuity: $2691 Total Food Cost: $17641 Total food cost is based on the $46 per person cost x 325. 300 for attendance, 12 for speakers, extra 13 for volunteers/organizers. Gratuity is 18%. Grand Totals So let’s sum things up here. Total Costs Hard Costs: $10700.00 Food Costs: $17641.00 Total:          $28341.00 Taxes:         $3685.00 Grand Total  $32026.00 Total Revenue Sponsorship  $20750 Registration   $74700 Grand Total   $95450.00 Total Profit $63424.00 Now what if the registration numbers were lower and they only got 100 people to show up. In that scenario there’d still be a profit of just under $26000. Closing Comments A couple of things to note: - I haven’t factored in anything for prizes. Not sure if any will be given out - We didn’t add in the booth space revenue - We’re assuming speakers aren’t getting paid, but even if they were at the high end its $12000 ($1000 per session), which is probably an inflated number for local speakers. - Note that all registrations were set to the “member” discounted price. The non-member registration price is higher. There is also an option for those that just want to show up for the opening keynote. There you have it! Let me know if you have any questions. D

  • Is it a good idea to make a game for one aspect ratio and arbitrary screen resolution?

    - by Mimars
    After several very small games I have decided to make something more standalone (2D) and playable. However, I have met the problem of every game that is going to be played in more screen resolutions. Basically, after some research I see that there are several solutions. This seems to be the simplest one: Let's say I define a constant aspect ratio for the game (16:9) and the whole game will be created for a resolution 1680 x 1050. The game will be rendered in this resolution and then I will be able to scale the render to match the player's display resolution. Therefore the game might be playable on almost any resolution, while it would keep the aspect ratio. So, if the game was run on 4:3 display, the top and the bottom of the display would be filled with black color. It seems easy, but my question is - Is this a good approach for a simple game? The game will be simple, but I want to maintain high quality.

  • Finding out which tile a mouse click landed in

    - by Shard
    I am working on an icometric grid based game and im having an issue trying to link a mouse click from the user to a tile. I have been able to split the problem into 2 parts which is first finding a rectangle that sourounds a tile, which I have been able to do but the second part of figuring out from the rectangle which tile the click landed in has got me stumped. Here is an example of a rectangle with tiles on the inside: The rectangle is 70px long and 30px high so if i use an input of say 30x(top)/20y(left) how would I go about determining which tile this fell into?

  • How to get experience in large scale databases?

    - by Justin
    I have written applications that are very small scale and the code I write works fine for them. But I have often wondered how the server side code I write would scale up from 100s of queries per day to millions. Also when looking at possible jobs/projects, people are often looking for developers with experience in this sort of high traffic database design so I would at least like to be able to say, I havent gotten to work on a project that was this popular, but I at least have tried to simulate it. Are there tools or frameworks that can generate a lot of traffic or at least simulate what would happen with traffic on different orders of magnitude so I could get some practice writing optimized code for higher traffic applicaitons?
