  • Using "Google Guava" in coding interviews

    - by kbgn27
    I attended a in-person interview recently and performed well. But surprisingly I got rejected. When I asked the HR for reason, he contacted the technical interviewer and told me that I was syntactically wrong while coding. I used Google Guava for coding. So my code looked like this: List<String> items = Lists.newArrayList() instead of List<String> items =new ArrayList<String>(); I know that the code will compile and work as expected.Is it ok to use third party libraries like Google Guava in interviews?

  • Does google see the output of document.write?

    - by merk
    I've got a site where people can list machinery for sale. Each item for sale has it's own dynamic page. On each of these pages we allow the person selling the item to have a link back to their own website. Some people only sell a handful of items and some people are selling dozens or hundreds of items. So in some cases we can have a 100 links back to their external site. Our SEO guy is saying this is bad (i'll open another question on that). So i was wondering if i take the links and spit them out using document.write, will that hide them from google and the other SE's ?

  • Why is it good to split a program into multiple classes?

    - by user1276078
    I'm still a student in high school (entering 10th grade), and I have yet to take an actual computer course in school. Everything I've done so far is through books. Those books have taught me concepts such as inheritance, but how does splitting a program into multiple classes help? The books never told me. I'm asking this mainly because of a recent project. It's an arcade video game, sort of like a flash game as some people have said (although I have no idea what a flash game is). The thing is, it's only one class. It works perfectly fine (a little occasional lag however) with just one class. So, I'm just asking how splitting it into multiple classes would help it. This project was in JAVA and I am the only person working on it, for the record.

  • Is it the job of a developer to suggest IT requirements?

    - by anything
    I am the only developer working on a web application which is nearing to its end. Now we are looking into making it Live in maybe a couple of months time. This is a web application for a non IT company. Though they have their own internal IT team, they have asked me on what will be the hardware requirements for the live servers eg. RAM, 32 bit or 64 bit. Shouldn't the internal IT team be doing this or since I am the only person working on the project is it my resposiblity to let them know of the any specific hardware requiremnts which may impact the performance of the project? The reason I am asking this question is that, I have not this before. All the times I used to be given a server and asked to deploy apps on it. I never used to worry about the server configuration etc.

  • Are there any surveys on to what degree developers like or hate scrum?

    - by dparnas
    Background: During a conference an analyst pointed out in a tweet that developers hate scrum. Myself and another person responded that this was not the case, and started discussing different scenarios on why developers would dislike scrum. One of the scenarios where that lazy developers are not able to hide in a scrum project. They are constantly challenged by the team to contribute. This discussion resulted in a blog post and video http://elsewhat.com/2010/05/20/lazy-developers-hate-agile-and%C2%A0scrum/ I've gotten three comments which I've tried to answer in a neutral way, but they comments do point out that there are some people who loathe scrum (and I am always 100% certain they are not lazy developers). Question Have there ever been a survey among developers on to what degree developers like or hate scrum ?

  • Integer type or not [closed]

    - by kira
    I am writing a program (in cpp) to check the primality of a given number The point where i am struck is , I need to check in between the program wether the value i obtained upon some arithmetic operations on the input is an integer or not i.e lets say input is 'a' I want to know how to check if 'b' is integer or not (FYI, b=(a+1)/6 ) My attempt for this : int main() { using std::cin; using std::cout; int b,c; int a; cout<<"enter the number"; cin>>a; b=(a+1)/6; c=(a-1)/6; if (b is an integer) cout << "The given number is prime"; else if (c is an integer) cin << "The given number is prime!"; else cout<<"The number is not prime"; return 0; }

  • Why CoffeeScript is an issue

    - by Renso
    Other than some obvious concerns, my main concern is support in the open source community. "anon" from the CoffeeScript team sent this to me after I requested input from the team to concerns I raised and wanted to get others' take on it:"Thanks for confirming that only idiots willingly program in Java and C#"or the following from the same person:"Oh and finally, you should definitely create jShort. Even though I know you will fail before you even start, I would love to laugh at your attempts and it would be perfect for you since you ride the short bus. "This kind of comment reflects badly on the CoffeeScript team and hence not an option for us as a company to consider. Another example of why some open-source community projects get no traction.

  • Stores Still Matter In The World Of E-Commerce

    - by Michael Hylton
    You may think that more and more consumers are moving their purchasing to the Web or mobile device.  However, according The NPD Group, Inc., a leading market research company, 15-20 percent of consumers in 2011 checked out products in stores before buying online, or called “showrooming”, for product categories like stand mixers, electric knives, sewing machines, and some floor cleaners. Other categories like power tools, hairsetters, and robotic vacuums are now beginning to show signs of the “showrooming” trend as well. It is doubly important to present a consistent, personalized, and relevant shopping experience for your customers, no matter whether they interact with you in-person in your store, with your sales agents or call center agents, over the Web, or using a mobile device.  Your goal is to make that experience across touchpoints as seamless as possible.

  • Could multiple uses of the same keywords in image alt attributes hurt SEO?

    - by saratogahiker
    Let's say on an e-commerce site that sells unique pens, on a particular pen's product page, the image of the pen has an alt attribute value of "unique red-striped pen"... and another product has "unique blue-spotted pen", etc... The keywords across all products being "unique" and "pen", which would also be helpful when it comes to SEO. However, if the person just goes to the general "unique pens" category page and sees a list of thumbnail images, each with the words "unique" and "pen" in the alt attribute, would that potentially have a negative impact with regards to SEO by having the same keywords too many times?

  • Translating with context

    - by translate
    Is there a way I can see the result of my work while I am translating? It is difficult to translate without context. If I could see how my work will appear while I am doing it, translating is much easier. Edit from Oli: I understand this question to be from somebody who is translating an application. Translators often only have a list of phrases to translate without being able to see where those phrases are used in the app. This person wants a way to quickly locate a string inside an application so they can understand the phrase better and provide the best possible translation.

  • What videoconferencing platforms work best for distributed software development teams?

    - by user11347
    Today I had a religious experience: I participated in a videoconference using a high quality Polycom system. This made a huge difference in communication quality -- people that I had a terrible time understanding previously now sounded like Shakespeare. Seeing a high quality video image was enormously helpful. I asked operations how much the Polycom cost and they said that it cost $20K new and $4K off eBay. So this solution doesn't work for people who work from home or who work in offices but are in groups of 3 or fewer people. My budget for a videoconferencing system is a few hundred dollars per person. Skype is not nearly good enough. And I haven't seen a consumer webcam that is good enough either. Does such a solution exist? I'm looking to collaborate both with people who are close by (in the same city but not in the same room) and far away (on different continents).

  • oDesk agency for subcontracting

    - by lorddev
    My question has to do with whether to create an oDesk agency (I've searched to verify that oDesk questions are appropriate). I have a project for which I was hired, and the client has given me authorization to subcontract a few hours of UI/UX expertise. I don't want to make the client hire the UI/UX guy directly; however, if I hire someone with my company account and then bill the client for the time, oDesk is taking 19% off the top (10% twice). I've checked their FAQ and filed a support ticket several days ago, but nobody has replied. If there's anyone who has had experience with oDesk agencies, do you think it can be handled this way? In other words, can I be the developer in my own agency while also having a UX person on the team?

  • What's a standard productive vs total office hours ratio? [migrated]

    - by marianov
    So it goes like this: we are keeping track of tasks using Redmine. We log time spent doing tasks, but at the end of the week if we add up all the time spent at those tasks there is no way a person has spent 40hs working. I think that's correct because offices have overhead (reading emails, politics, coffee, distractions). What would be a normal productive time vs total time spent ratio? Other areas in the organization just measure time spent in the office (with the rfid badges that open the door) but we don't like that approach and we are trying to convince Auditing to measure us using redmine instead.

  • After upgrade my webcam mic records fast, high pitched, and squeaky only in Skype (maybe Sound Recorder problem too)

    - by Dennis
    After an upgrade to 11.10 which probably also updated Skype to 2.2.35 (not sure because I never checked the version before) the sound that comes back from an echo test is very high pitched and squeaky. I'm not sure if when in a call if the other person can't hear or just doesn't know what they are hearing. I am using a USB Logitech C250 Audacity records fine, gmail video chat works fine, but if I start sound recorder I get a "Could not negotiate format", followed by "Could not get/set settings from/on resource". I don't know if this is a Skype problem or a wider Pulse problem. My only real needs are the gmail and Audacity, though I have a couple of contacts that I can only Skype with.

  • Should I be concerned about hAtom tags on my blog?

    - by Sid
    I am using a theme that automatically adds hatom-entry, hatom-feed classes on my WordPress blog. I read that such tags/classes should be used for syndicated content. Anyway, then I ran a Rich Snippet Tool, which threw a "HAtomfeed" error. So I removed a "hfeed" div tag. Now, should I be concerned? Can this cause any problems? I still have a couple of these classes (listed below), and I just hope they do not effect my site's ranking. For now, these are the tags the Rich Snippet Tool has detected: hatom-feed hatom-entry: entry-title: entry-content: published: author: fn: person-name: url: Appreciate your help! Edit: All the content on this weblog is unique and written by me and others. Thought I'd share that.

  • Is the Apple iPad for you now or should you wait until the iPhone 4 is released?

    The iPad came to the market last Saturday and as always with the Apple marketing came the big lines and small tents that never seen a camp site but the Apple stores. There are the people that want one right away and want to be the first person to own the new shiny device from Apple and there are the people that are willing to wait a month for the device with 3G instead of just WiFi only. The iPad is an interesting concept, a bigger iTouch that can be used as a replacement for your Netbook, Kindle,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • In some games, we just let the main() loop be the Player object or Table object?

    - by ????
    I was thinking that let's say if there is a game of Blackjack or MasterMind, then we should have a class called Dealer or ComputerPal, which is how the computer interact with us (as a dealer for Blackjack or as the person giving hints for MasterMind). And then there should be a Player object, and the way to play one game is aPlayer.playGame but I noticed that a book was just using the main() loop to act as the player (or as the Controller of the game), calling the Dealer methods to dealer the cards, ask for player's action, etc... 1) Is this just a lazy way to model all the proper objects? 2) If more objects are to be added, who should call the aDealer.dealCards and then ask for aPlayer.askForAction? (because it is strange to let the Player handle all the logical steps). Should there be a Table object that handle all these logic and then to play one round of game, use aTable.playGame? What is a good object design for such game?

  • Are there any third-party components that replicate OneNote?

    - by TomK
    I have a client that wants me to add a OneNote-like interface to a desktop .NET application I'm creating for him. We cannot be sure all users will have Microsoft's OneNote installed, so I can't use InterOp or the like. So I am looking for a third-party component that provides the same fluid/freeform interface as OneNote, for capturing images, text, lists, etc. Any suggestions? I'm surprised that not only can I find none with Google, I'm not even finding others like me asking the question. I can't be the only person who thinks this is functionality worth including in our programs.

  • Wireless connectivity Wifi 7260 on Ubuntu 10.04

    - by user292332
    I am trying to install Wireless networking on Dell Latitude E5440 Wifi 7260- Ubuntu 10.04.(Yes I know it is old- see the complication below) I did get the wired connection working but our classrooms are wireless. I have tried to upgrade to version 12 last year but to my horror during the first week of class the nfs mounts did not work for multiple users. I never thought to test for more then one person at at time!! I have not been able to find a fix for the upgrade so I must remain at 10.04. NFS mounts are a must for student home directory access on the servers. All desktops are 10.04 as are the servers. Does anyone have a solution to the wireless problem in version 10.04/ or the nfs mounts solution in version 12. Thank you so much. Val

  • Rendering trillions of "atoms" instead of polygons?

    - by Baring
    I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

  • Does Your Business Really Need a Search Engine Optimization Specialist?

    If you're an individual or an organization planning to employ a search engine optimization professional, you might first want to consider the possibility of doing this work yourself. Certainly, a search engine optimization consultant can boost your site and perhaps help save you time and effort, yet the fact is that SEO is hardly an advanced science, and there are just a handful of authentic professionals within the field. So, if you depend on somebody else to be in charge of your search engine optimization, there's a high probability that the person will not possess a great deal more knowledge than you. And if you lack any knowledge, all the relevant information is easy to obtain.

  • What is the primary use of Vertex Buffer Objects?

    - by sensae
    From what I've read, it seems VBOs are purely for performance. I'm working on a very rudimentary learning project in lwjgl and I'm just trying to figure out what more advanced features of the library I should be delving into, and what their use is. My understanding is that VBOs allow a person to keep vertexes in VRAM while they aren't currently being drawn in a scene. In my case, I'm just drawing quads and performance probably isn't a concern at all, but I'm trying to piece together what's happening under the hood. If I'm drawing quads directly, I'm drawing from the CPU memory, correct? Also, if I'm not doing any checks for visibility, does that mean I'm rendering absolutely everything in the "scene", regardless of whether its in view? Are VBOs a way to store objects and only render what's needed?
