• Avoiding "double" subscriptions

  - by john smith

  I am working on a website that requires a bit of marketing; let me explain. This website is offering a single, say, iTunes 50$ voucher to a lucky winner. To be entered in the draw, you need to invite (and has to join) at least one friend to the website. Pretty straightforward. Now, of course it would be easy for anyone to just create a fake account and invite that account so, I was thinking of some other way to somehow find out of possible cheating. I was thinking of an IP check on the newly subscribed (invited) user, and if there is the same IP logged in the last 24 hours, and if that's the case, investigate more about it. But I was thinking that maybe there is a more clever way around this issue. Has anyone ever though about this? What other solutions did you try? Thanks in advance.

• Why do so many APIs boast about being RESTful?

  - by John Hoffman

  I have noticed that many APIs I have encountered such as Facebook's old API and Skydrive's API boast about being RESTful. Hence, I looked up what REST means on Wikipedia (http://en.wikipedia.org/wiki/Representational_state_transfer), but I don't understand why do APIs boast about being RESTful. Doesn't RESTful just mean that an API works via communications across the web such as via HTTP? What's the big deal? This sounds like any API that relies on third-parties.

• Do you know your DNS server?

  - by John Paul Cook

  If you don’t know your DNS server is valid, you need to find out before July 9. The FBI found rogue DNS servers and replaced them with clean, safe DNS servers to protect the public. These safe, clean servers will be turned off on July 9, 2012. If your computer was compromised to use the rogue servers, it will stop resolving DNS queries on July 9 when the clean servers are turned off. The FBI has provided full technical details at http://www.fbi.gov/news/stories/2011/november/malware_110911/DNS-changer-malware.pdf...(read more)

• If your algorithm is correct, does it matter how long it took you to write it?

  - by John Isaacks

  I recently found out that Facebook had a programming challenge that if completed correctly you automatically get a phone interview. There is a sample challenge that asks you to write an algorithm that can solve a Tower of Hanoi type problem. Given a number of pegs and discs, an initial and final configuration; Your algorithm must determine the fewest steps possible to get to the final configuration and output the steps. This sample challenge gives you a 45 minute time limit but allows you to still test your code to see if it passes once your time limit expires. I did not know of any cute math solution that could solve it, and I didn't want to look for one since I think that would be cheating. So I tried to solve the challenge the best I could on my own. I was able to make an algorithm that worked and passed. However, it took me over 4 hours to make, much longer than the 45 minute requirement. Since it took me so much longer than the allotted time, I have not attempted the actual challenge. This got me wondering though, in reality does it really matter that it took me that long? I mean is this a sign that I will not be able to get a job at a place like this (not just Facebook, but Google, Fog Creek, etc.) and need to lower my aspirations, or does the fact that I actually passed on my first attempt even though it took too long be taken as good?

• Dual Booting Windows 7 and Ubuntu 12.04. Partition Sizes?

  - by John F.

  I'm about to reinstall Windows, so I thought that I'd try Ubuntu out on a partition just for fun. My question is, how large should my partitions be for each of them? I know this various depending on what you use, so i'll give you a general idea of what I have, and what I have in mind. I'm currently running: Windows 7 Professional (64bit) RAM: 4GB CPU: 2.5Ghz Quad Core processor HDD: 500GB GPU: 1GB Nvidia GeForce I have around 130GB in Steam games, and some heavier applications like Photoshop CS6, Sony Vegas Pro 11. But other Applications I use are: Chrome Skype Dxtory Fraps OpenOffice BitTorrent and other assorted smaller programs. So, I was thinking that I would give my Windows partition about 150-200GB, my Ubuntu Partition around 20GB, and the rest to shared storage. I'm not really sure if I'd need more or less on Ubuntu, because I've never used it and I'm not really sure what kind of apps i'd be using over there. This would also be a clean install, so I'd be wiping my HDD, creating the Partitions in GParted, then installing Windows with Ubuntu following that. Any critique you could give me? Maybe explanations to what the /root, /boot and /home partitions I hear are about? Thanks in advanced if you actually read this lengthy thing! Any help is appreciated. (x

• Add an entry for Ubuntu on Windows 8 boot loader

  - by John

  I have installed Ubuntu 12.10 by creating free space in Windows 8 and then using that space to create 3 partitions, one for SWAP, one for GRUB (mounting point is /boot) and one for the actual OS. I did this so the Windows 8 boot loader wouldn't be overwritten in case I ever wanted to remove Ubuntu. I can still boot into Ubuntu if I select the boot loader from the BIOS. I want to add Ubuntu to the Windows 8 boot loader and I've been told to use EasyBCD. The issue with that is it doesn't actually direct Windows to the GRUB file, but rather to something like autogrub0.mri. I have found another programme called Visual BCD which will allow me to actually set the bootloader paths and drives. From here, I don't quite know what to do. I believe I have it set to the correct drive but I don't know if I'm directing to the right file. I think it's /boot/grub/x86_64-efi/grub.efi. I don't know if that's the right file, if I need to remove /boot or if the / need to be \ as that's what Windows uses. Sorry for such a lengthy post, please help!

• Web-based data generator

  - by John Paul Cook

  One of my coworkers told me about Mockaroo , a web-based data generator. I needed some test data for upcoming blog posts, so I decided to give it a try. It’s pretty good. I had to use Firefox because of problems running Mockaroo on Internet Explorer 11. Using the defaults except for changing the format to SQL, it generated output that looked something like the following. Mockaroo is so good that it generates fake data that could accidentally be real, such as email addresses. Consequently, I edited...(read more)

• How can I load .obj files in the Soya3D engine?

  I recently just found soya3d. I want to import .obj files, but it seems to only accept .data files. How can I import .obj files?

• No sound after clean install

  - by John Cheednik

  Did a clean install of Ubuntu 12.10 and everything working great except for the sound. Ubuntu doesn't even seem to be recognizing the fact my HP dv6000 has the capability of making sound! I have the dummy output problem, and when I try to open alsamixer using terminal I get the message that no such file or directory exists. I can't get it to recognize any soundcards or audio devices at all. I've been working on the problem for a couple days now and have even taken the laptop apart to ensure that all cables are properly attached... When I go into the PhoenixBIOS there are no sound options that I can find. The laptop does make a loud beep if I press buttons in the BIOS, but once it boots to the hard drive, the thing is mute. HELP!

• BI Beginner: Why to Use Excel 2013 Now

  - by John Paul Cook

  Most corporations and many individuals are slow to adopt new versions of Microsoft Office, particularly if the upgrade to the previous version was very recent. Excel 2013 is a special case and offers significant productivity enhancements. If you do business intelligence work or otherwise make your living with Excel, adding (notice I didn’t say upgrading to) Excel 2013 now makes a lot of sense. The Power View feature in Excel 2013 is a completely sufficient reason to add Excel 2013. It has to be enabled,...(read more)

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• Install Windows7 on drive with Ubuntu 12.04 already on. Is my plan good?

  - by John F

  I have Ubuntu 12.04 working fine, but need W7 occasionally. I just wanted to check that my plan for installing would work? Any help appreciated. Current partitions are: Partition....@ File System @ Mount Point @ Size.....@ Used.....@ Flags /dev/sda1....@ ext4........@ /ext4a......@ 37 GiB...@ 776 MiB..@ boot /dev/sda2....@ extended....@.............@ 122 GiB..@ -........@ ./dev/sda5...@ ext4........@ / ..........@ 37 GiB...@ 6 GiB....@ .unallocated @ unallocated @.............@ 7 GiB....@ - ...... @ ./dev/sda6 ..@ ext4........@ /home.......@ 77 GiB...@ 32 GiB...@ .unallocated @ unallocated @.............@ 65 GiB...@ - .......@ /dev/sda3...@ linux-swap..@.............@ 7 GiB....@ - .......@ My plan is to: - boot to ubuntu from USB ISO - change sda1 to NTFS - install W7 to sda1 - use the "Master Boot Record repair" utility to configure dual boot so I can see my original ubuntu installation as well as W7. Have I missed something? I'm concerned as to what the 776MB is that will be overwritten by the change to NTFS. It seems large for just the MBR? Would also appreciate it if anyone can explain what sda5 and 6 are being used for? Is sda5 Ubuntu and sda6 my data? Thanks in advance.

• What are some good game development programs for kids?

  - by John Giotta

  I know a very bright little boy who excels in math, but at home he's glued to his Nintendo DS. When I asked him what he wanted to do when he grew up he said "Make video games!" I remember a few years there was mention of a MIT software called Scratch and thought maybe this kid can do want he wants to do. Has anyone used any of the "game development" for kids softwares out there? Can you recommend any?

• Remote Access to Owncloud Server

I cannot figure out how to access it from the outside. So far I've: Successfully setup port-forwarding on my local router. I've done so via 'single port forwarding' and 'port range forwarding' Ports 80, 443, 3306 (Apache-Full and MySQL) Successfully obtained my external IP address. I've also tested this magic number from within the network at #insertIPhere/owncloud and it did work. Successfully setup the server using SQLite Successfully setup the server using MySQL Created the following exceptions in my firewall: Allow In Port 80 (Apache Full) Allow In Port 443 (Apache Full) Allow In Port 3306 (MySQL) Tried connecting from several different remote networks, as to troubleshoot something on their end As far as trying to access it, I'm doing so through Google-Chrome and Mozilla Firefox trying to reach the server through #insertIPhere/owncloud using the above public IP address. So what have I missed, and how do I access my server from outside? Thanks in advance for your help and time, and I apologize in advance for what will probably result in my noobish mistake in networking. I've looked at the official documentation.

• RSpec + Selenium tests for .NET on Windows

  - by John

  I'm a Rails developer doing TDD on a Mac with RSpec, Capybara and Selenium webdriver. Now I have been asked by my company to use this approach for a .NET on Windows environment. What is the best way of doing this? I could just install Ruby and use RSPEC, Capybara and Selenium webdriver for integration testing. But what about unit tests? I also looked at NSpec, but I'm not sure if I can combine that with Capybara or Selenium for integration tests. What would be a good approach here?

• Is multiple domain names and links from same IP causing poor search engine rankings?

  - by John

  I have an ecommerce website which is not doing so well in Google. I am trying to improve this of course, and am looking at some possibilities for why it isn't doing well. The website has four domain names, all of which have been indexed by Google. A few months ago I applied 301 redirects to any requests for two of the domain names so now it is down to two domain names (one is a .net, the other is a .com.au, the others were .net.au and .com). I prefer to use my main domain name (the .com.au), but one of the names has been around for a long time and has more inbound links. According to a PageRank tool, both are PR2. It is a Classic ASP site and up until recently had a lot of querystring parameters. In the last week or so I added URL rewriting so there is now no parameters for most pages. I don't do 301 redirects from the old URLs but instead I add the META canonical tag indicating the preferred new URL. At the same time I redesigned the site and improved title tags, META descriptions, and H tags but it hasn't been long enough yet for Google to index many of these yet. I also looked at what pages Google has indexed and strangely it has some strange pages in the index, there are a lot of pages which are actual keyword searches (more a bunch of random letters than an actual word). What I mean is that it is as if they had typed in something to search for in my search box - there are no links to pages like this and the only way of getting this is to type something in to the search box). So I added a META robots tag with noindex,nofollow anytime that I render pages like this. Years ago I set up a fake price comparison site which lists all my products and links back to my site. It has a different keyword rich domain name but is on the same server and same IP address. It's a completely different layout but does have the same product categories and product descriptions (although I have stripped formatting out of them so they are not identical except in text). I also have a few blog sites which again are on the same server/IP and all have advertising for the website. My questions are: What should I do with the multiple domains, just use one, or continue with two or more? Should I add 301 redirects, not just the META canonical tag? Any idea about Google indexing my search results page, and did I do the right thing with the META robots tag? Is the fake price comparison site likely to be causing problems? Are all the links to the site from other domain names but the same IP address likely to be causing problems? Thanks for any help. Sorry for so many questions in one.

• How do I make Ubuntu go past the splash screen?

  I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with ubntu and the dots turning from white to orange forever. This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing. How can I make my computer finish booting again? I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash. dmesg cat kern.log

• Ubuntu 12.10 wont boot

  - by John Mark High

  im new to using Ubuntu and just bought a HP Pavilion g6-2240sa with windows 8 pre installed. I made a bootable USB with Ubuntu on it and installed alsongside windows, for 2 days it worked fine, I got into Ubuntu by doing an advanced restart from windows 8 and then booting Ubuntu from the partition it made. When i did the advanced restart today there was only 1 HDD i could select ( there were 3 before windows, a restore partition that was already there when i got the computer and Ubuntu) so i booted from the USB again and re-installed Ubuntu. then did an advanced restart and the 3 partitions where there again, i booted from Ubuntu and now heres my problem. I get the Ubuntu background when its loading then its just a black screen with some writing, its not on long enough to read, then just a black screen with a white _ and the top left corner that does nothing, i have to restat the computer and it auto boots into windows 8. im a little confused as the first time i installed Ubuntu it worked fine until the partition dissaperd), the second time i installed i did everything the same except it found the old Ubuntu so i reinstalled it and now is donst work.

• htaccess 301 redirect help needed

  - by John

  Due to some issues in my site many pages are visible as duplicate using : www.example.com/page.html?task=view but it's content is exactly same as www.example.com/page.html. One way is to use http 301 redirect from www.example.com/page.html?task=view to www.example.com/page.html when anybody fetches page with arguments. But links like www.example.com/page.html?task=view will remain visible to outside world. Another way is canonicalization which I don't want to use as it is difficult to insert the tag in Joomla CMS. I want to hide www.example.com/page.html?task=view from external world. Is it possible to change the url from www.example.com/page.html?task=view to www.example.com/page.html ? I mean if there is href link of www.example.com/page.html?task=view in my web page, it should be visible to external world as without any arguments. This is different from using 301 to convert externally accessed page : www.example.com/page.html?task=view to without using arguments in .htaccess.
