• Come Aboard. We're Expecting You...

  - by KKline

  Those of us over a certain age (read - old as dirt) can remember the theme songs to certain TV shows better than we can the National Anthem. Try these lines out and see if you don't immediately remember the tune that goes along with them: Come and knock on our door | We've been waiting for you ... Makin' your way in the world today | Takes everything you've got ... Just some good ol' boys | Never meaning no harm ... Thank you for being a friend | Travel down the road and back again ... So when I...(read more)

• Upgrading to Mono 2.8

  - by Oli

  Mono 2.8 was recently released boasting a couple of large performance improvements. It's far too late for it to make it into Maverick and I'm fairly inpatient. I don't use Mono for anything mission-critical (just playing music and sorting photos) and if it breaks everything related to Mono, I can probably either live with it or fix it. I'm aware of how much I stand to lose if I mess things up. So with that acknowledged, does anybody here know how to build Mono in a way where it could be dropped in to replace the current Mono (2.6.7)? By this I mean ideally mirroring the packages that Ubuntu uses so that if the worse does happen, I can just downgrade the packages. Or is there a PPA that does all this for me?

• No wireless and display issues on Dell Inspiron 1210 (Mini 12)

  - by Bryan M.

  I recently upgraded a friend's Dell Mini 12 (Inspiron 1210) from Ubuntu 8.10 to 10.04 netbook edition. After installing, and performing the available updates, I'm unable to detect any wireless networks (it knows it has a wireless card, but won't list any active networks). There also seems to be an issue with the display drivers: when scrolling, resizing, or drawing any windows there is a noticeable lag as I watch the screen redraw. As if there are no compatible display drivers installed. All these problems go away the moment I boot up a version of 8.10. But I'd like to keep 10.04 if possible. Are these common problems? Everything I've read suggest this is laptop should be compatible. Any suggestions? Thanks.

• Change language encoding for file uploading

  - by jc.yin

  Previously we were running a Wordpress site on a Mac OS Server machine. We had several hundred images with Chinese characters for the image names. Now we're trying to migrate to a Ubuntu system and everything is fine except the images. Every time I try to upload an image with a Chinese name via FTP, I get the following message: "MyImage contains illegal characters. Please choose an appropriate text encoding" I have no idea how to solve this issue, do I need to somehow change the system language encoding in Ubuntu to allow for image uploading? Thanks

• How do I open up firewall while keeping it safe?

  - by d3vid

  Since I've installed Firestarter I have encountered connectivity issues that are all resolved by disabling the firewall. I'd prefer to have the firewall running and allow all the traffic I normally use: Wired network + wireless network, whichever I'm connected to, or both (1) OpenVPN VirtualBox internal network Samba (for accessing shared Windows folders and sharing folders to Windows) (2) BitTorrent And everything else I use that I can't think of :) All the above works without a firewall. I thought Linux was super secure (I update regularly). Do I really need it? (1) I used the Firestarter wizard and selected wlan0 as my primary connection, now whenever I plug in a network cable, I lose all connectivity. Should I just redo the wizard for eth0, or will I then lose wlan0? (2) If it makes a difference I'm sharing a directory that I share between local users using bindfs. See my answer to Good and easy way to share files on local machine

• What's the difference between Scala and Red Hat's Ceylon language?

  - by John Bryant

  Red Hat's Ceylon language has some interesting improvements over Java: The overall vision: learn from Java's mistakes, keep the good, ditch the bad The focus on readability and ease of learning/use Static Typing (find errors at compile time, not run time) No “special” types, everything is an object Named and Optional parameters (C# 4.0) Nullable types (C# 2.0) No need for explicit getter/setters until you are ready for them (C# 3.0) Type inference via the "local" keyword (C# 3.0 "var") Sequences (arrays) and their accompanying syntactic sugariness (C# 3.0) Straight-forward implementation of higher-order functions I don't know Scala but have heard it offers some similar advantages over Java. How would Scala compare to Ceylon in this respect?

• I'm building a theme for tumblr and the {HasPages} doesn't seem to work properly.

  - by Muhammad

  I've put the HTML draft of the theme so far, with minor CSS edits. Currently I have all the block posts and everything else that's essential to a tumblr theme but I can't seem to get the {HasPages} block to work properly. I've tested it on a different tumblr, also. There are pages created and I already have provided some basic CSS for it just in case. But there isn't anything showing up. Has anyone has this problem and if so, is there a solution I'm missing? The code to display the pages is included. {block:HasPages} <ul> <li><a href="/">Home</a></li> {block:Pages}<li><a href="{URL}">{Label}</a></li>{/block:Pages} </ul> {/block:HasPages} Also, is this a valid web masters' question. I'm not sure.

• Should I group all of my .js files into one large bundle?

  - by Scottie

  One of the difficulties I'm running into with my current project is that the previous developer spaghetti'd the javascript code in lots of different files. We have modal dialogs that are reused in different places and I find that the same .js file is often loaded twice. My thinking is that I'd like to just load all of the .js files in _Layout.cshtml, and that way I know it's loaded once and only once. Also, the client should only have to download this file once as well. It should be cached and therefore shouldn't really be a performance hit, except for the first page load. I should probably note that I am using ASP.Net bundling as well and loading most of the jQuery/bootstrap/etc from CDN's. Is there anything else that I'm not thinking of that would cause problems here? Should I bundle everything into a single file?

• Unity GUI pauses/freezes for less than a few seconds

  - by Ahmad Nassri

  I've just got my new Lenovo ThinkPad X220 with Intel HD graphics (I'm not sure what the chip is) and I've installed Natty. Everything works great out of the box, except there are short pauses/freezes in the UI that randomly occur, they last less than 2 seconds, actions are still taking place in the background (like typing) when the UI un-freezes I can see the characters I've typed, the app I've clicked, loaded . I can confirm that this is only happening with the new Natty 3D interface, I've tried 2D and the classic interface and there were no issues. Googling this topic seems challenging as I can't relate the problem in keywords. And I keep getting results relating to full GUI freeze which I don't have. This is troubling since I have Natty 3D running on older machines without any issues . I wonder if anybody else have experienced this or came across this issue before. Thanks.

• Problem with Python3 picking Python2 package

  - by zetah

  I installed python3-numpy package, but trying to import it in Python3 interpreter I get this: $ python3 Python 3.2.3 (default, May 3 2012, 15:54:42) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import numpy Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/zetah/.local/lib/python2.7/site-packages/numpy/__init__.py", line 128, in <module> from version import git_revision as __git_revision__ ImportError: No module named version >>> Looking in Synaptic I see python3-numpy is installed in /usr/lib/python3/dist-packages/numpy/ Why is it picking wrong package and what can I do to remedy this? Update: OK, in my ~/.profile I have this line: PYTHONPATH=$PYTHONPATH:$HOME/.local/lib/python2.7/site-packages but if I remove this line then my Python 2.7 local packages (which I build from source) wont work Update 2: Everything seems to work perfect without $PYTHONPATH. I guess it was in my .profile file for nothing Please close this question

• WiFi not working on Dell Inspiron 1564

  - by Zack Warren

  hope you can offer some help! I'm new to Ubuntu (and Linux for that matter), but I managed to install Ubuntu 12.04 yesterday on an old Dell Inspiron 1564 Laptop. Everything works fine, with the exception of the wireless connection. Using my wired ethernet, I was able to look up several solutions which seemed as if they would work, but I've had no luck. Currently, wireless does show as enabled, but all wireless networks are disconnected, in fact, none of the networks are even listed (and I can see them on other devices in the home). Let me know what you need to help me! Thanks in advance!

• Game Maker Studio Gravity Problems

  - by Dusty

  I've started messing around with Game Maker Studio. The problem I'm having is trying to get a gravity code for orbiting. Here's how i did it in XNA foreach (GravItem Item in StarSystem.ActiveItems.OfType<GravItem>()) { if (this != Item) { Velocity += (10 * Vector2.Normalize(Item.Position - this.Position * (this.Mass * Item.Mass) / (Vector2.DistanceSquared(this.Position, Item.Position)) / (this.Mass)); } } Simple and works well, things or bit and everything is nice. but in Game maker i don't have the luxury of Vector2's or a For-each loop to loop threw all the objects that have a mass. I've tried a few different things but nothing seems to work distance = distance_to_object(obj_moon); //--Gravity hspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) vspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) thanks for the help

• Smooth Sailing or Rough Waters: Navigating Policy Administration Modernization

To help carriers better prepare for what lies ahead LOMA's Resource Magazine asked Karen Furtado, partner of Strategy Meets Action, to help them chart a course in Navigating Policy Administration Selection, the cover story of this month’s issue. The industry analyst and research firm recently asked insurance carriers to name the business drivers for replacing legacy policy administration systems. The top five cited, according to Furtado, centered on: Supporting growth in current lines Improving competitive position Containing and reducing costs Supporting growth in new lines Supporting agent demands and interaction It’s no surprise that fueling growth, both now and in the future, continues to be a key driver for modernization. Why? Inflexible, hard-coded, legacy systems require customization by IT every time a change is required. This in turn impedes a carrier’s ability to be agile, constraining their ability to quickly adapt to changing regulatory requirements and evolving market demands. It also stymies their ability to quickly bring to market new products or rapidly configure changes to existing ones, and also can inhibit how carriers service customers and distribution channels. In the article, Furtado advised carriers to ensure that the policy administration system they are considering is current and modern, with an adaptable user interface and flexible service-oriented architecture. She said carriers to should ask themselves, “How much do you need flexibility and agility now and in the future? Does it support the business processes and rules that are needed for you to be able to create that adaptable environment?” Furtado went on to advise that carriers “Connect your strategy to your business and technical capabilities before you make investment choices…You want to enable your organization to transform for the future, not just automate the past.” Unlocking High Performance with Policy Administration Transformation also was the topic of a recent LOMA webcast moderated by Ron Clark, editor of LOMA's Resource Magazine. The web cast, which featured speakers from Oracle Insurance and Capgemini, focused on how insurers can competitively drive high performance by: Replacing a legacy policy administration system with a modern, flexible platform Optimizing IT and operations costs, creating consistent processes and eliminating resource redundancies Selecting the right partner with the best blend of technology, operational, and consulting capabilities to achieve market leadership Understanding the value of outsourcing closed block operations Learn more by clicking here to access this free, one-hour recorded webcast.

• Does XNA 4 support 3D affine transformations for 2D images?

  - by Paul Baker Salt Shaker

  Looooong story short I'm essentially trying to code Mode 7 in XNA. Before I continue bashing my brains out in research and various failed matrix math equations; I just want to make sure that XNA supports this just out-of-the-box (so to speak). I'd prefer not to have to import other libraries, because I want to learn how it works myself that way I understand the whole thing better. However that's all for naught if it won't work at all. So no opengl, directx, etc if possible (will eventually do it just to optimize everything, but not for now). tl;dr: Can I has Mode 7 in XNA?

• Black screen and blinking cursor for a while during Startup

  - by Soumyadip Mukherjee

  I've installed the Ubuntu 12.04.1 "rock solid" release. Everything works fine apart from the fact that during start-up the usual purple screen and Ubuntu logo doesn't appear. Only a black screen and blinking cursor is visible. Then after a while, for a fraction of a second, the Ubuntu logo and purple screen comes and disappears to the login page. I tried Plymouth but it didn't help in solving the problem. It did end up changing the logo to a more artistic one. Can any one please help? Ubuntu is installed on my ASUS 1225c netbook.

• Space Stations as Envisioned in the 1970s

  - by Jason Fitzpatrick

  Boy, they sure were ambitious back in the 70s; while today we’re happy to have a small apartment-sized environment in orbit, back then they were dreaming of entire cities in space. Courtesy of the NASA Ames Research Center archives, we’re treated to artist renderings of the space colonies of the future as imagined from the 1970s. The artwork spans visions of space colonies from 10,000 to 1,000,000 citizens strong–some of them include everything from bodies of water to office buildings. Hit up the link below for more images.

• Starcraft 2 - Third Person Custom Map

  - by Norla

  I would like to try my hand at creating a custom map in Starcraft 2 that has a third-person camera follow an individual unit. There are a few custom maps that exist with this feature already, so I do know this is possible. What I'm having trouble wrapping my head around are the features that are new to the SC2 map editor that didn't exist in the Warcraft 3 editor. For instance, to do a third-person map, do I need a custom mods file, or can everything be done in the map file? Regardless, is it worth using a mod file? What map settings do I NEED to edit/implement? Which are not necessary, but recommended?

• GParted doesn't see any partition

  - by Diego

  What I am trying to do couldn't be more logical I think. I have a 40gb drive with two partitions, Xp and Ubuntu. I have dual boot, everything boots and works perfectly. I have about 9gb free in the Windows partition When I run Gparted I only see 40gb unallocated space, booting from Gparted Live CD. What the hell is going on ? I've read everywhere this is a common problem, however it has no sense something like this remains unsolved by gparted developers, considering what I am trying to do is the very basic step anybody wanting to migrate from Windows to Linux would od Something like this honestly doesn't give anything else than frustration Could anybody on this forum be so kind to explain whats' going on ? Thanks

• Ubuntu Oneiric + Awesome WM

  - by janjust

  I upgraded to oneiric ocelot, running awesome wm. Everything works, more or less, fine but one thing I've noticed is that now my menu fonts and my menu symbols are larger than I'd like them to be. I used to set them in font settings, but now (for one I don't even know where font settings are anymore, I tried gnome-tweak-tool) the font-settings are gone? Surely I'm missing something. My prime example is the program evince whose symbols are ginormous. Any hints how to tweak it?

• Lynx "Alert!: Unable to connect to remote host."

  - by Deepend

  I'm pretty new to Ubuntu server. I'm running Distributor ID: Ubuntu Description: Ubuntu 12.04.4 LTS Release: 12.04 I have installed Lynx via sudo apt-get install lynx everything installed fine but when I try to connect to a website it just seems to time out. When I run lynx google.com it goes to a blank screen with a blue line at the bottom. There is yellow text on the line which says "Making HTTP connection to google.com" but it just sits there. Eventually after 5 - 6 minutes it just goes back to the normal terminal window If I run the below on its own lynx I get the same blue line with the same text "Making HTTP connection to google.com" but after 30 seconds or so it briefly turns to a red line with "alert!: lynx unable to connect to remote host" written on it. I have installed lynx locally and it works fine. Does anyone have any ideas?
