• Is the Lenovo Ideapad Z570 fully compatible with 12.04?

  - by umpirsky

  I'm looking for some notebook that will run on Ubuntu perfectly. I like LENOVO IdeaPad Z570, but I'm not sure how it will perform on Ubuntu. I heard people are complaining about wireless problems. Here is full configuraion: Processor Intel Core i5 2430M 2.4GHz - 3.0GHz Chipset Intel HM65 Express Memory 4GB DDR3 1333MHz Graphics NVIDIA GeForce GT 520M 1GB HDD 750GB SATA II Wireless 802.11b/g/n, Bluetooth 2.1 Network adapter Ethernet LAN 10/100Mbps Ports VGA, HDMI, 3x USB 2.0, eSATA Does anyone have experience with this model? Any problems noted? I heard there is a test suite, how can I install it? Maybe I can boot live CD and try it myself before buying it. But, unfortunately, sometimes something works on live CD, but not when you install it. I guess critical components here are graphics and wireless. Any feedback would be appreciated.

• Team Fortress 2 Is Now Free [Gaming]

  - by Jason Fitzpatrick

  Wildly popular computer game Team Fortress 2 is now free Previously $10, Valve dropped the price for Team Fortress 2 to $0. The new model is a “freemium” one wherein the majority of the game is free but you can purchase small upgrades in-game (like expanding your backpack from 50 slots to 300 slots to hold more gear or purchasing items instead of searching them out in the game).

• Prevent product key from being used on multiple virtual machines

  - by Nahum Litvin

  I have a software product. it will probably run on VMs that have no network connection at all. I want the user to pay for each VM the user runs. I thought to ask the user for some kind of hardware ID and provide him with serial that is unique for his machine. But user can just copy the VM image and than have two machines running? So I thought of having a security dongle. But how can I prevent user from running two VM's on the same machine both connected to the same dongle? This should be only basic defense so that actual hacking will be required to breach the license and not only spinning one more VM.

• Missing feature in Hyper-V from Virtual PC

  - by Kevin Shyr

  One thing I really miss is the ability to create shared folder between host and guest.  Virtual PC does this well, you can create Shared Folder to be used every time, or just this one.  I have read some posts on how to do this.  Some people suggest using ISO Creator to package up the files and mount the image to DVD drive, but what I need is truly a "shared" environment, so I'm currently looking into creating Virtual switch and creating an internal network between the host and guest.  Let's see how that works out. I would have loved to give Virtual SAN Manager a try, but I don't have a local Fibre Channel to set one up. I guess this might be an extension to my original post:  http://geekswithblogs.net/LifeLongTechie/archive/2011/05/05/windows-virtual-pc-vs.-hyper-v-virtual-machines-vs.-windows-virtual.aspx

• wifi works only after connecting through wire

  - by orustam

  I have fresh installed ubuntu 12.04. it is my first ubuntu installation and i'm a bit confused about the network connection. Wifi shows up and connects(at least it shows that the connection is established), but i can't open any pages, i've tried to ping some sites and it fails either. If i try to connect through a wire it works, what is interesting to me is that after i used my wire connection i can use my wifi properly without a wire pluged in. i think it probably has to do with my settings? I tried to find a solution but can figure it out on my own. My Proxy set to none(have applied it system wide) Please help me if you have any clue:)

• How do I create a WiFi hotspot sharing wireless internet connection (single adapter)?

  - by Ruppesh Nalwaya

  I know how to create a hotspot when connected to a wired network, but when I am using internet from a WiFi connection, this disconnects the wireless connection the moment I activate the hotspot. In Windows I can use Connectify Hotspot, which enables me to share the internet connection from the same wireless adapter as I am creating an access point on. As you can read on the technology overview page: Access Point mode allows you to create a hotspot using the same Wi-Fi card that you are using to access the Internet. How do I do this on Ubuntu?

• Lubuntu 13.10 - Laptop Loses wireless after sleep

  - by user206217

  I'm running Lubunu 13.10 on an hp G62 - I'm new to Lubuntu having used ubuntu previously, but I've made the switch as my laptop is now getting toward the lower end of acceptability, and I'm delighted with how well it runs. Anyway, I'm having an issue that if I close the lid of the laptop it won't reconnect to the wi-fi when I open it again, and I'm not sure how to even force it to scan for a network - I have to restart it at the moment - and then it always connects perfectly. The router is a BT Business Hub 405. Any help much appreciated - thank you.

• .htaccess 301 Redirect for wildcard subdomains

  - by Steve

  I run Wordpress in Network mode, which means I can have multiple websites running off one installation of Wordpress. Each website runs as a subdomain. Wordpress handles this using .htaccess, and a wildcard subdomain pointing to the location of Wordpress, so there are no actual subdomains created in cPanel; just a wildcard subdomain in cPanel, ad Wordpress handles the rest. I want to 301 redirect http://one.example.com/portfolio to http://two.example.com/portfolio. If I only have 1 .htaccess file in the web root of example.com, how do I achieve this?

• Are things slow for you today - Check your DNS

  - by simonsabin

  Domain name resolution is a very common cause of delays when doing anything over the network whether its accessing a web page or connecting to SQL Server. Everything uses DNS. TCP/IP works with IP addresses and not friendly names. When using names you have to have a way of resolving names to IP addresses and thats what DNS does. If your DNS is wrong then you'll get delays and also potentially odd results. For instance if you have multiple DNS servers configured you may find that occasionally...(read more)

• Can I rightfully claim this as my own project if I recieved help online?

  - by Brad Guy

  Basically I'm new to network programming in Python, so I went on a tutorial online to find out about it. Using what was taught in the tutorial (creating a socket, connecting to ports, etc), I modified the code so that I made a program where two computers can send messages to one another. If I were to apply for a job and show this to my interviewers, would the code for it technically be mine? It is fair to say that I didn't modify the code by that much; However, what if for example I modified it into something like a tic-tac-toe game, where two users play each other from different PCs, would the code then be mine? I just don't want to look like a plagiarizer hence why I ask.

• Honor titles for outstanding professionals from different companies? [closed]

  - by Alexander Galkin

  If this is an off-topic here, please move or advise a more appropriate forum. Microsoft MVP (most valuable professional) title is well known as an honor title for professionals not working for MS directly but who did a lot to popularize MS technologies. This title does not require any certification or any other proof of knowledge by the nominee and is awarded solely upon the one's contribution to community. As a member of Intel Developer Network I am also aware of Intel Black Belt award, that is in many aspects similar to Microsoft MVP. But this is all I know. Are there any other honor awards from top players in software industry?

• Can a local multiplayer iOS game display differently for each device?

  - by Rahil627

  I've seen games which display different data for two devices, but not more than two. If possible, can it be accomplished using GameKit? EDIT: More specifically, I was thinking local multiplayer via bluetooth or wi-fi on an iOS device. Most games I've seen display the same screen synchronized across all of the devices. I understand games that network across the internet do this, often using a server, but I haven't seen any examples of a 3+ device local multiplayer iOS game. I just want to make sure it wasn't some kind of limitation.

• How are dependant quests generated in Guild Wars 2?

  - by Aufziehvogel

  I recently read that Guild Wars 2 uses a system where the creation of quests depends on which actions user took when they were presented another quest. An example was: There might be a quest to protect a person. If users do not take this action, the person might be kidnapped and later there is a quest to rescue this person. Is there any information on whether the creation of these quests is somehow automatic? From the article it sounded like automatically, but from the specific example you could also guess that people just created a task-set where they added conditions (Task 1 taken: OK; Task 1 not taken: Show Task 2). From what I heard about AI they might also have implemented some sort of a huge neural network to make decisions?

• Logitech Wireless Keyboard & mouse not working aftesr upgrade to 12.04?

  - by deerjay99

  I upgraded my Dell Dimension 9200C to 12.04 Precise Pangolin with no issues, I ran it fine for a night but when I went back in a couple days later my Logitech Wireless Keyboard K350 and M510 mouse weren't active when booted. I can boot into an older version from the main the boot screen the mouse and keyboard work, but the network stack is gone. It says the networking manager on this version is not compatible. I'm scratching my head, it isn't the mouse and keyboard, they work fine on my dual boot, and they load fine in Knoppix. They did work fine on 12.04 for 1 night. Open to suggestions before I re-install completely.
