• How to identify potential for becoming a programmer

  - by Jacob Spire

  There's heaps of information out there on hiring someone who's already a programmer. (Or claims to be one.) But what about identifying someone who has the potential to become a programmer, with little or no knowledge? Aside from the obvious things to look for (smart, gets things done), are there any interview questions and/or tests to determine whether one has the potential to become a programmer? Note: I'm not asking how to tell whether I can learn programming, but how to tell someone else is right for it.

• Two "subdomains" crossing search results

  - by LuckySpoon

  My question relates to two websites, each of which is a "Calvary Christian College", however in two totally different locations and unrelated to each other entirely (except by name, and domain). All schools in the state are issued a .qld.edu.au, in this case calvary.qld.edu.au and calvarycc.qld.edu.au. Now what's interesting is that these domains are crossing each other in sitelinks for searches such as "calvary christian college townsville" (if you check the sitelinks 2/6 are to a different domain). I've put a demotion in for this ages ago (we control calvary.qld.edu.au), however we're seeing no change on the results page. I have been able to get the owners of calvarycc.qld.edu.au to submit demotions for our domain, which should go in sometime this week. What can we do to tell Google that these websites are not interchangeable, despite both appearing as "subdomains" of qld.edu.au. We can possibly open channels of communication with the administrators of qld.edu.au but will need to tell them what we need to change, and at this point I'm out of ideas.

• wrong SEO result for staging website

  - by OCD

  Hi, We have a domain with URL, lets say: http://www.xxxxstaging.com/abc.php?id=10 which is having a pretty good ranking for some keywords in google. However, this is our staging website and due to some historical reason, it was exposed to public. Now we have a production domain (the one we want to be publicly available), say: http://www.xxxxproduction.com/abc.php?id=10 which have exactly the same html output as xxxxstaging.com our question is, for the exactly same keyword search, it never appear in any page of google. Is it possible for us to "switch" the ranking in google, either tell the robot that they are indeed the same website, or tell google to change it for us? Thank you.

• Disable outbound links without letting others know that

  - by tadoman

  Is there a way I can tell google not to follow external links ( pointing to other sites) without letting other know. I know you can disable outbound links by putting rel=nofollow or something in robots.txt. But that's something others can see as well. I'm just wondering if there's a way to tell google not to follow those links without letting others know that... like a setting in webmaster tools or something similar ( there's definetly one way. I could set an exception in my conf file for my server to check the user agent to be "googlebot" and then serve a different version of robots.txt. So that when a different user would check that link it would return a different robots.txt thant the one served to googlebot. However I'm not too sure google would be too happy about this) Thank you

• Disabling IPv6 on a single interface

  - by ijw

  I'm slightly weirded out by the fact that Ubuntu won't process ipv4 DHCP unless you explicitly tell it to, but will happily take ipv6 RAs unless you tell it not to. Is there any way to change the default behaviour to be 'do nothing unless I explicitly turn it on'? (Note to answerers: I'm not looking to globally disable ipv6, or completely turn off autoconf. I'm looking to disable autoconf by default (as in, I don't want ipv6 unless I say so in /etc/network/interfaces, in the same way that I don't just get a v4 address unless I've explicitly turned on dhcp). What's happening is that, for any interface that's up - e.g. has an ipv4 config - a v6 address tends to just turn up on the interface as well, despite the fact that I've not enabled that explicitly. The solutions to date are fine as far as they go, but if I disable v6 or autoconf globally, I can't then re-enable v6 on a per-interface basis with a simple command in /etc/network/interfaces. I'm fairly sure I'm asking for the moon on a stick, mind you.)

• Hibernation is still missing from menu in 13.10 after enabling via polkit. How to enable?

  - by LiveWireBT

  I know that since 12.04, we need to add a policykit rule to enable hibernation (see question How to enable hibernation? and the Official Documentation). I can successfully bring my laptop into hibernation mode with sudo pm-hibernate or sudo s2disk, so the rule is in place and works, but the hibernation entry is still missing in the menu. I can tell from looking through the source of the indicator-session package (but not understanding the whole code) that there is still a hibernation menu entry in the code and it should be displayed when the system is capable of hibernating. Please calm down if you're enraged by this. This is very unlikely to be a conspiracy, but rather a bug/regression on a deeper level, which can happen when you move code around or replace it. Question: What needs to be done in 13.10 to properly tell indicator-session that the system can hibernate? Possible duplicate: Hibernation still not available - No activity, because saucy was in development at that time, so out of scope for AskUbuntu. Related bug report: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/1232814

• Burn MP4 to CD in ubuntu 12.04

  - by xyc

  I have an mp4 file (115,8 mb). I want to burn it to a Sony CD-R (700 mb) to watch on tv. I tried to do it with DeVeDe from ubuntu software center but it always give me this error: "Conversion failed. It seems a bug of Mencoder." Can anyone tell me an other method to burn my mp4 to cd? Or can anyone tell me how to fix DeVeDe's error? I use a TOSHIBA computer (64 bit) with windows 7 home premium and ubuntu 12.04 LTS (installed via wubi.exe). Thx.

• Is it really a security problem to have non secure assets on an ssl page?

  - by blockhead

  My understanding is that this is just an example of being overly cautious, but if my checkout form contains an unsecure asset on it, that doesn't endanger anybody's credit card numbers from being caught by a man-in-the-middle. I'm asking this because every once in while, maybe because of cached content or whatnot, somebody writes in saying that they are seeing this "error" (even though there are no unsecure assets on my page), but they want an explanation. So yes, I can tell all about encryption and certificates and trust and men-in-the-middle. But what do I tell them about this. How do I convince them that the site is 100% safe (and if it isn't let me know that I'm mistaken!)

• I am new to game development, what do I need to know? [closed]

  - by farmdve

  I am unsure if this question is a duplicate, I hope it isn't. Are there any resources on the terminology when doing game development? Because, even if you tell me to learn some graphics API, how would I understand the things it does, if I am not well into the terminology(voxel,mesh,polygon,shading). What about the math that is involved in the game(geometry) or the concept of the gravity,collision detection in the game and their respective maths? I am very bad at math, never was good, because I have ADHD, but I won't give up just yet. I look at a game, and I see "textures", but how am I walking on them, how do they take substance so I don't fall off of them? And depth? This is what I need information about, not just a link to a library like SDL(which I have compiled under MinGW and MinGW-W64) and tell me to learn it and the cliché answer "start simple/small". I hope the question(s) are not too vague.

• Ubuntu 13.04 is showing some error while opening my computer

  - by Singh

  Few months before when I was using Ubuntu 12.04 then I found some errors while starting my computer. Due to this problem I had given my CPU to a shop to repair it I don't know what he has done to my CPU but I only know that finally I got my CPU with Ubuntu 13.04. The technician was unable to make any partition and I also think that he had installed 13.04 over 12.04 and so now my computer is showing some error when I'm starting my computer the error is as follows: error: attempt to read or write outside of the disk 'hd0'. grub rescue _ Before showing this error, few times my computer was working very slow. So kindly someone tell me that is there any way by which I can start my computer. Please also tell me that what things I have to keep in mind while using Ubuntu so that in future I find no difficulties(errors) while using Ubuntu.

• 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.'

• Anyone know about AppDynamics? Does Microsoft already have something similiar? Event viewer? Im confused

  - by punkouter

  We have a big collection of java (80%) and .Net (20%) apps.. And the people in charge want a way to monitor the applications somehow. So they told me they are interested in AppDynamics? I have spent a bit looking into it but I still don't get it. Can someone tell me what its about ? From my understanding it seems like you would someone inject the AppDynamics API in your code to tell about differnt events that occur? So sounds like Event Viewer ? I am on the .NET side of this and seems to me we can just write data to a log and report off of that data.. I don't get what the additional complexity of using'AppDynamics' does. Maybe it is overkill ??

• E-Commerce Website

  - by haargott

  I am planning to create an e-commerce website for users to buy products and services. In this website I want users to register and also participate in something like a browser game, where every user may receive some questions which they have to answer. For each question they successfully answered, they receive points and the number of collected points will decide on which rank they are. Edit 2 Currently I am considering using only HTML, CSS, JavaScript, PHP, SQL to design this e-commerce website. Together with this I was thinking about learning jQuery as it may help me, but I am not sure if I should code everything specifically by myself or just use the library to make it faster. 1) Could you tell me if those languages are sufficient enough for creating such a website described? 2) Could you tell me what kind of free software tools and frameworks are most appropriate to use when creating this e-commerce website?

• What is the the best way to become an iPhone developer?

  - by Noah89

  I have no experience as a programmer but I'd like to become a iPhone developer. Some people tell me to learn java because it is a Object Oriented Language. Other people tell me to go with C++. However, everyone advises me to actually learn any language and learn what programming is all about before I actually develop for iPhone. Please, let me know what would be the best choice and what books would be good for a total beginner and any website that offers any good tutorials. Thanks in advance for all the feedback.

• Insanity&ndash;Day 1

  - by D'Arcy Lussier

  Some people do those posts about “Here’s what I’m going to do to change my life”. I don’t really like those. I’m a “don’t tell me what you’re going to do, tell me what you’re doing/have done” type of guy. So while I could say how I’m going to change my life and be healthier and happier and thinner in 60 days, I’m just going to tell you how I’m progressing through the Insanity workout. Insanity is a workout-in-a-box. It’s a collection of DVDs that you work out to. Nothing new here, except that the program is intense. It’s core tenet of the program is intensity – you workout at an elevated heart rate for 3 minutes with a short break in between, as opposed to traditional interval training where you go hard for a short time and recover for a few minutes. The other aspect of it is commitment. There is a timetable to follow – you workout 6 days a week with one rest day. This isn’t meant to be a “pick it up whenever you feel like it” type of program. The videos themselves are kind of…I don’t want to say low quality, but not as polished as I expected. Maybe that’s what they were going for. By that I mean they show shots of cameramen and the production equipment during the workout. Otherwise, it’s the Insanity leader Shawn T. leading a group of pretty fit folks through this gruelling workout. And ultimately, those little production nit-picks are irrelevant compared to the actual workout. Holy crap. I haven’t done an aerobics class in like…ever. And watching the video before my actual workout, I thought “That doesn’t look too hard”. Believe me, it is. No weights, no machines, just various exercises done in circuits and with increasing speed. By the end of the workout, I was drenched. So that was day one. Some stats just so I can track it: I’m 286 lbs at my last weigh-in a week ago or so. Should be interesting to see what 60 days of this does! D

• Configuring httpd.conf to handle wildcard domains and multiple scripts?

How do I tell httpd.conf to handle those properly as well? How can I tell httpd.conf that handle everything after the 'forwardslash', exactly as it does on the main site, but pass a parameter flag like ?domain=alpha (Cross posted at: http://stackoverflow.com/questions/11365566/configuring-httpd-conf-to-handle-wildcard-domains-and-multiple-scripts)

• Observer Pattern Implementation

  - by user17028

  To teach myself basic game programming, I am going to program a clone of Pong. I will use the Observer design pattern, with an interface between the input and the game engine. However, I'm not sure what the interface should do. One idea I had was for the input interface to tell the game engine that (e.g.) the screen was clicked, then to let the game engine decide what to do with that information (shoot a bullet, for example). Another idea I had was for the input interface, having caught the mouse click, to tell the game engine to shoot a bullet. Which method would be better for me to use?

• Jumping Login Box after Lighdm Multiple Monitor workaround

  So I used this workaround to sort my resolution at the login screen when using multiple monitors with Lightdm. #!/bin/bash XCOM0=`xrandr -q | grep 'VGA1 connected'` XCOM1=`xrandr --output LVDS1 --primary --auto --output VGA1 --auto --right-of LVDS1` XCOM2=`xrandr --output LVDS1 --primary --auto` # if the external monitor is connected, then we tell XRANDR to set up an extended desktop if [ -n "$XCOM0" ] || [ ! "$XCOM0" = "" ]; then echo $XCOM1 # if the external monitor is disconnected, then we tell XRANDR to output only to the laptop screen else echo $XCOM2 fi exit 0; Found Here: How to force Multiple Monitors correct resolutions for LightDM? It works great. However, now when I am on my login screen, the login box seems to jump to between the two displays. Any advice as to how I could make it stay on one display? Thanks

• Upgrade to Ubuntu 13.10 disabled track pad, brightness, sound on Lenovo Z570

  - by Vizir

  I just upgraded to Ubuntu 13.10 using Ubuntu's software update. It seemed to go all right, however after the system restarted and booted up Ubuntu 13.10, it began experiencing several problems. Some of them were due to expected conflicts with the updated OS, however right now I cannot figure out why certain hardware functions are now "broken" and how to fix them. As far as I can tell, these are the sound (permanently muted), mic (picks up no sound), brightness (set at maximum brightness regardless of using keyboard shortcuts or moving the screen brightness slider) and trackpad (mouse does not move, however plugged-in USB mouse does) This sounds to me like a driver issue, however I cannot figure out how to re-enable my drivers, re-install them, or whatever I have to do here. This did not happen durring my upgrades from 12.04 to 12.10, or 12.10 to 13.04, so I'm at a total loss as to why this happened this time around. My computer is a Lenovo Z570, dual-booting Ubuntu and Windows 7 from GRUB 2. Windows is working fine as far as I can tell.

• Minecraft program frame rate is very slow

  - by Cade

  I have recently downloaded Minecraft to Ubuntu 12.04. It launches and plays successfully, however- the frame rates for the game are extremely slow. They never go past 9 fps and usually drop below 3 fps. I have been a Windows XP user for years and have just recently switched to Ubuntu, so I'm not an expert with this OS. My video card is a Diamond Stealth s60 with Radeon 7000. I don't know what other information you guys need but if you ask for it, and would please tell me how to get to it, I will tell you as soon as I can. Thanks for your help.

• About to graduage from good school without any progamming skills

  - by newprint

  Not sure if it is good place to ask this question, but found this section to be suitable. I am about to graduate from good school (in the US) with Computer Science degree, having good grades and high GPA. I have no freaking clue how to write a good program, how to properly test it... nada, zero. We were never been tough how to write software. Ye, sure the Comp. Architecture class is important, and I can tell you a lot about how MIPS processor works, and I can tell you about Binary Trees and Red-Black Trees and running time of operations in Big Oh, but it has nothing to do with programming in "real" life. For god sake, none of my classmates know how to use STLs or write templated code !!! To be honest, I found that many of my classes to be waste of time. What should I do ? How to step into real life and learn how to program ?

• How Microsoft copy the result from user for Bing.

  - by anirudha

  from some days before i read about the problem google show with another search engine Bing who come from Microsoft. well google show that bing copycat and Microsoft show that they not. i am not known matter much more but predict something that maybe true if google are right in what they tell. if MS really copy the search from User then they use Live service who used by all user who use the internet or on the internet. see the snapshot i have in this snapshot they tell that Help improved search results,internet safety and Microsoft software by allowing Microsoft to collect and retain information about your system, the searches you do and the websites you visit. Microsoft will not use this information to personally identify or contact you. Learn more so why they need the research on what user search on internet even the not contact but user their is no reason as well as bing. well their is a example who maybe possible they  use for bing.

• A c++ program that computes the min and max of f(x) for a rectangle inputed by user

  - by StreetBallerX

  So bassicly this is the problem quoted from my teacher : "You have to write a program in C++ that computes the minimal and the maximal value of function f(x,y) obtained on an integer point in a given rectangle [a, b] x [c, d]. Your program should prompt the user to input numerical values of a, b, c and d, as floating point numbers, which are expected to be in a range from -100 thru 100. In case when minimal or maximal values do not exists, your program should output appropriate messages. f(x,y)=x+x*x+x*x*x+y+y*y " So before anyone tell me that i should try do it myself , i'll tell them that ive been trying to do it myself for the past 8 days but my deadline is aproaching and i just cant figure it out its a really simple program but i just cant understand it ... I wont post my attempts because all i saw in these forums is that when someone posts their try and a milion people start to say dont look it this way thry this and bla bla and the guy who posted it was just wondering for minor thing ... so what ever thank you all in advance and thats it :)

• NFS issue: clients can mount shares as NFSv3 but not as NFSv4 -- or how to debug NFS?

  - by tdn

  Problem description I have a file server running Debian. On it I have a few NFS shares. When I mount the shares from a client using NFSv3 (mount.nfs 10.0.0.51:/exports/video /mnt -o vers=3,soft,intr,timeo=10), it works. However, I would like to use NFSv4 because of improved security and performance. When I try to mount an NFSv4 share on malbec the mount command just hangs and finally times out after 2 minutes. How do I make the clients mount the NFSv4 shares as NFSv4? How do I troubleshoot NFS? There is no information in the syslog on neither client nor server. What are any errors in my configuration?
