• Help with Dial Up

  - by iSeth

  I am trying to set up a computer for my friend that has dial up. The problem is nothing I try can detect the modem. GnomePPP can't find it and I can't figure Kppp out. I've been looking all over the net on my ethernet trying to find an answer but I keep getting routed back here. I have also tried using scanModem and it finds something like Conexant Systems, Inc. HCF 56k Data/Fax/Voice Modem but the rest of it is really confusing. I've also tried this but I'm not very terminal savvy and it didn't work. It seems like I have to compile a driver but I don't know which one or how to do it. I have also tried multiple modems. Any help would be appreciated. Thanks EDIT: scanModem thinks the modem is disabled on startup. EDIT: I reinstalled Ubuntu but the problem persists.

• Receive anonymous users' input by web upload form or email. Any online service for that?

  - by sja

  Are you aware of any online service or online "platform" allowing users, not previously registered, to upload pairs of picture+comment to a database? It would be a collaborative database of picture+comment pairs. I'm not going wiki or googlegroup, picasa or such because I'd like the user to have the least to do to participate, that is e.g.: take a picture with his phone and email it to an email to an email address. Or go to a web page with an upload form, type in a description, hit OK and that's it. And the goal is also that it be as hassle-less to put up as possible. Yeah I know, it can't programme itself to my requirements :) by I'm suspecting there's a tool or tool combination going a decent way through my needs. Thanks for any info/advice! SJA (NB the final goal is a kind of crowd-sourced census of specific urban items. If you have comment about the potential for spam-overload of my idea, other than "you're doomed", you're welcome!)

• iOS: game with facebook challenges

  - by nazz_areno

  I created a game for iPad and I want to challenge my facebook friends. I follow the iOS tutorial in "facebook dev docs", with the "Smash game", but it doesn't explain how to challenge a friend directly to a game. I will explain with an example: I want to start a new match and I want challenge a friend on facebook. Then I send him a request to install the app and when I detect that its app is installed I send him a request to play vs me. Then, when I finish the match I sent him my result and my friend do the same thing. But if I and my friend don't finish the match it is not possible to send another challenge. This scenario is not explained by facebook sdk. Is it necessary to use another instrument to do this situation?

• What is the most serious limitation of Unity?

  - by ashes999

  Having read this heated question about Unity vs. UDK vs. ID something, I'm curious to know: what the repeatedly-hit, most crippling limitation(s) of Unity? In order to keep this question non-subjective, again, I'm talking about the top repeated offender(s) of Unity are. This is something that, as a Unity user, you really wish someone had told you about before you started using it. I have heard from someone that Unity does not deal well with version control, since it generates a lot of binary files (which are un-diffable). This, to me, is not really crippling as I work alone. Thoughts?

• How do I run Microsoft Explorer 8 plus on Ubuntu?

  - by user169487

  First off, you should know I'm a Ubuntu newbie who has become passionate since my strangely low-priced Dell computer showed up with Ubuntu loaded on it and it could do almost everything I need from a computer. But now I've got a problem. I know, it's like asking how to use a cassette player on your computer, but in South Korea EVERY website is made to work with exclusively on MS Explorer PLUS Active X, which Microsoft finally killed with 9. Hence, I have to use 8, as there are some Korean sites I need to access for searching, banking, etc. So I see that the way to go is to load PlayOnLinux, but then I it tells me to delete these. Do I really have to do that? Should I just hit "Install Anyway"? Or would that be just asking for trouble?

• How can I use a CanoScan N640Pex scanner over a USB/parallel cable?

  - by detly

  I have an old CanoScan N640Pex flat bed scanner and a USB-to-parallel port cable through which I can connect it to my PC. Unfortunately neither Simple Scan nor XSane detect the scanner. I'm running Ubuntu 12.04 (plus updates and backports) with kernel 3.2.0-31-generic. dmesg tells me this when I plus the cable in: [256411.641910] usb 7-1: new full-speed USB device number 10 using uhci_hcd [256411.872392] usblp0: USB Bidirectional printer dev 10 if 0 alt 1 proto 2 vid 0x067B pid 0x2305 [256411.872417] usbcore: registered new interface driver usblp lsusb shows this device for my cable: Bus 007 Device 010: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port The device node created is /dev/usb/lp0 crw-rw---- 1 root lp 180, 0 Sep 9 17:46 /dev/usb/lp0 There is no extra information from any of these commands when I attach the scanner to the cable and power it on, though. I suspect I might need to change something in /etc/sane.d/canon_pp.conf, but I have no idea what to put for the ieee1284 line, since there is pretty much zero documentation for that parameter. So how can I get it to work?

• Syncing properties across a game server

  - by Vaughan Hilts

  I'm beginning to implement a simple scripting system into my networked server, and I've hit a snag. Before, I've been wrapping my calls into functions on objects that manipulate objects, but lately I've been finding this to be a pain for simple things. For example, if I set 'player.HP = 1'.. this works server-side. But the player side never sees this change unless I explicitly send a packet to inform the client. For many things like map swapping that require more complicated changes, like change X, Y, Map and do this.. I have a function. That's fine. But what about these small properties I want to sync?

• Line6 UX1 soundcard and Ubuntu

  - by the_drow

  I own a Line6 UX1 soundcard and I would like to make it work for Ubuntu. I have followed the instructions here and it worked. But at some point I upgraded my kernel version (not sure what uname -a prints but it's related) and it stopped working. Here's what uname -a prints: Linux ubuntu 2.6.32-29-generic 58-Ubuntu SMP Fri Feb 11 20:52:10 UTC 2011 x86_64 GNU/Linux I figured out that maybe it's installed per version so I used svn update and hit make again. My guess was right as it copied the relevant files to the new version's folder. I restarted and still nothing. Should I revert to an older version? Or is there a solution here?

• Should iOS games use a Timer?

  - by ????

  No matter what frameworks we use -- Core Graphics, Cocos2D, OpenGL ES -- to write games, should a timer be used (for games that has animation even when a user doesn't do any input, such as after firing a missile and waiting to see if the UFO is hit)? I read that NSTimer might not get fired until after scheduled time (interval), and CADisplayLink can delay and get fired at a later time as well, only that it tells you how late it is so you can move the object more, so it can make the object look like it skipped frame. Must we use a Timer? And if so, what is the best one to use?

• OpenStack + Ubuntu 12.04

  - by csgeek

  Supposedly openstack can be installed easily under Ubuntu 12.04 LTS. I've installed 32 and 64bit versions of Ubuntu Server with the same behavior. sudo tasksel check OpenStack hit Okay then I get a tasksel: aptitude failed (100) I've seen: http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin and https://github.com/EmilienM/doc-openstack documentation, but I was hoping that since it was an LTS released and it was an option in tasksel that I was simply overlooking something obvious and it's just a matter of selecting the right checkbox and hitting okay. Too much wishful thinking?

• SEO problem for site with 2 domains [closed]

  - by Harry

  Possible Duplicate: What is duplicate content and how can I avoid being penalized for it on my site? I have two domains pointing to the same site. I want both domains to co-exist, they share most of the same content, but they differ in design and they are aimed at different markets / rivaling communities. Is there a way to let google know that these two domains are the same site and don't cause me to get hit with a duplicate content penalty? Any other general SEO tips for this situation would also be welcomed. Thanks. Come on man, why was this closed. The linked page is completely irrelevant for me.

• Unable to boot from USB boot drive for AMD Athlon 64

  - by Nagarjun

  I am trying to install Ubuntu 13.04 ISO for AMD64 Athlon processor using USB drive (8GB). I did create a bootable USB using the USB installer from Win7 intel 32bit processor (followed steps from here: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows). This USB is unable to boot on my AMD64 bit processor. The bios is able to detect the USB and once I change the boot order to USB and save exit from bios, I get a message saying "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS CONTINUE" and unable to proceed further. However earlier to this I have successfully installed Ubuntu 13.04 on to my laptop which has Intel 32 bit core i5 processor with the same procedure but my desktop which has AMD64 is failing. I also tried to create the USB installer on my desktop which has the AMD64 bit processor and tried booting which also resulted in the same error. (My desktop currently has Win XP) Please help as I have run out of options. thanks, Nagarjun

• Calculate initial velocity of a 3d vector-based projectile

  - by Frotty

  Okay, so I got a Projectile with 2 Vectors, position and velocity. I now want to calculate the initial velocity for it in order to reach a specific point on the map. Or actually, how high has the start z-velocity to be (because x and y are probably defined by a speed variable) in order for the projectile to hit the marked position. The projectile is influenced by a constant gravity vector. All calculations are done 32 times per second. I want this, because I don't want to use a parabola function, so the projectile can still be influenced by other sources, simply adding some velocity. I didn't really find anything referring to that topic and would be glad for every helping answer, Thanks.

• 3d Collision Handling

  - by TobSpr

  I have trouble while detecting collisions on my 3D-Game. I have set-up Rays, to detect collisions (Screenshot) and my main-rountine already analyzes them. But now there's the question what to do with that. One possibility would be, to move the player back to the last position, but that's dirty, and does not work if the player can walk in multiple directions (e.g. if the player runs along a wall). My question is, what to do with the collision data / or in which direction, by which amount move the player? I'm sure there is an algorithm for that (as for almost all is).

• Reduce weight in healthy way - Day 3

  - by krnites

  So I am on Day 3 and what I did today was totally opposite of what I should have done. It seems I will take ever to loose what I had aim for. Today I had ate more than 5000 Calorie, had soda drinks and very oily indian food. On my Day 2 post some one commented that with the number that I have I will loose 1 lbs in a week, but my friends it seems I will gain 5 lbs in a week. I have to straighten my act and really focus on what I want to achieve. I am going to hit the gym and going to burn atleast 500 calorie today.Piece of advice - don't eat fried, oily  and junk food.  Try to have as much as vegetables in your food. I understand its not possible as being a normal person and not a diet freak I know its impossible to be away from Taco or burger and not drink Coke, but to achieve something you have to loose something.

• Turned off my computer and o it's opened up in grub. How do I tell it to boot into lubuntu?

  - by Magpie

  It's just a commandline. I have tried my usual trick of sticking a usb with lubuntu in there to see if I can boot from my usb but I get a boot error (I normally wouldn't using that usb). GNU grub version 2.00-7ubuntu11 also just using basic things I know I hits ls then tried boot hd0 but it says: you need to load the kernel first I have no idea how to do this. I looked at the commands and most of them hve obscure names that are not helpful. UPDATE: I hit exit and that allowed be to boot from usb. Hopefully I will be able to find what I need to install to get it booting normally again from there.

• Google search preview shows content not on the website

  - by SDG

  My website google search entry is messed up. In the preview in google search results, I get things like cracks, serials, random ip addresses. I scanned all files and my computer for viruses and malware and could not find anything. I also tried to download and reupload all content from a friend's computer and still that content persists. I also scanned the source code of all files, but the content does not appear in any file. Google also does not detect any malware on the website, as seen in their webmaster tools. I have searched using the same keywords in other search engines such as bing and yahoo and the search results there are fine. I am quite clueless as to what the causes would be for this and what would be a possible remedy.

• How do you hibernate/suspend Ubuntu like Windows or both at the same time?

  - by All Star Geek

  I'm using an ASUS laptop with Windows 7, and I just installed Ubuntu alongside Windows yesterday, using the no-risk option. I noticed, though, that I can't hibernate Ubuntu the way I did with Windows to save time, and, every time I use Ubuntu, I have to shut down to go into Windows, which has a slow boot. Is there any way that I could have Windows and Ubuntu hibernated at the same time so I can access both easily (preferably without having to hit a function key within seconds). When I try to hibernate or suspend Ubuntu with Windows shut down, the screen just turns blue and doesn't shut the computer off like a Windows hibernate or sleep.

• How do I add restrictions for users to sign up before they can access web site?

  - by user1867842

  How do I get my webpage not to go back when they hit the back button and are logged out and how can I add a web page to be blocked like FACEBOOK doesn't let you get into their site with out having a page or a account with them, and if you try to put something in the url and try to go to something on their site it gives you a web page that says "you have to be logged in first" . Like I don't want someone going to the url of the "index" page before they have signed up as a member they need to make an account first then they can have access to the "index" page. How do I do this. I have a website so far that has a database and the website has 5 pages so far and two of them which is the login and sign up page which are both used with php and mysql and they work fine. How do I restrict access to the main website by first having the users sign up with me for an account.

• ubuntu 13.10 secondary monitor - doesn't redraw properly

  - by Daniel

  Hi I've just installed Ubuntu 13.10 on a Lenovo w350 and am having some issues with graphics driver. standard nouveau drivers work great on the laptop display but when I attach an external display it goes bad on the external monitor, seems it's not re-drawing properly. (Photo attached). I've tried other drivers but none of them detect the external monitor when connected. Any ideas? 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K1000M] (rev a1) screenshot of effected monitor -- http://i.imgur.com/UZWMpQO.jpg UPDATE 1: I have noticed that if I leave the System Monitor open the display improves. Wierd. UPDATE 2: If I leave a video going the lag/flicker issues stop.

• Google Analytics

  - by DavidMadden

  My first post.  Working with Google Analytics (GA).  What an incredible tool this is for those that are wanting to know about their site traffic.  GA allows the user to drill down to the screen size of any mobile sources that came in contact with his site.  The user is even able to know region demographics of visitors and the types of browsers and languages being used.  This is a great tool to help determine your target audience and what direction of growth one may be needing to take.GA has Real-Time currently in beta but it already allows the user to see some information.  I can already detect that I am viewing my site from Louisville, KY and what page of my site is being accessed.  I highly recommend using GA for the sheer plethora of data available.
