  • Is there an idiot's guide to software licensing somewhere?

    - by Karpie
    Basically, my knowledge on the issue is zilch other than the fact that open-source and closed-source exists. I'm a web developer (not a designer in the slightest), so I look online for things like icons. I've always been a big fan of these icons, which have a Creative Commons Attribution 2.5 License. As far as I can see, this license says 'do whatever you want with them as long as you have a link back to me somewhere'. Is that assumption correct? Just today I found a new icon set, with a much more confusing license (found here), and to be quite honest I have no idea if I'm allowed to use them or not. At the moment I want to just use them for toy stuff that might never see the light of day, but then my source code is stored on Github, is it legal to store the icons there where they're publicly accessible? If I put them on my personal website that might have ads on it to make me five cents every now and then, is that legal? If I use them on a site that offers a free service to users, is that legal? If that site then starts making money (via things like paid subscriptions) or gets bought out by someone (highly unlikely but one day possible) is that legal? Is there some noob guide out there that explains all this stuff, because I would hate to start using this sort of stuff now only to have to change it all later. Even if I buy the icons, there's still licensing issues that I don't understand! :( And this sort of stuff keeps popping up more and more often...

  • Frame rate upsampling codec/player/software?

    - by djechelon
    Hello, I recently noticed that when I play both HD and SD videos on my HDMI TV at 1080p 60Hz from my computer, the motion is not fluid as I would expect. As far as I know, it could be because the 24fps video needs to be upsampled by the codec to match the 60Hz output of the monitor. But, as far as I know, the upsampling is done by simply repeating each photogram for a certain amount of frames. I usually play MKV videos with VLC. Do you know if there is a player or codec that performs the upsampling by interpolation like some 100Hz TVs do? I recently saw an LG led TV play a 24fps 720p video at 100Hz with an incredible motion fluidity, and I simply wonder why can't my computer do! I have an NVidia card. Does PureVideo help? I'm a noob with these things. Thank you.

  • Sniff packets using tcpdump

    - by denisk
    I have a completely noob question. I want to see all packets that come to my computer from particular site (google.com). So I start tcpdump sudo tcpdump -i eth0 host google.com and enter google.com in a browser and hit enter - nothing gets captured. I can't figure out why it happen. What do I do wrong? Edit It appeared that I was listening to the wrong interface. I had changed eth0 to any and it worked. It was ppp1 that needed listening. Thanks for your answers!

  • Can't install software from Ubuntu software center

    - by Casbar
    I've been experimenting with Ubuntu 10.04(64bit) inside a VirtualBox VM. This isn't my first experience with Linux, but I'm still very much a Linux noob. Whenever I try to install software from the Ubuntu Software Center, the installation gets interrupted and I get a warning that this installation requires untrusted sources. I can install anything I want using apt-get, it's just the gui that doesn't work. I've done research on the issue and taken the following precautions with no result: under software sources Allowed Canonical partners Allowed source code Changed the download source to main server I get no errors when running an apt-get update. Can anyone shed some light on the issue?

  • Cannot access windows share

    - by Wrigley
    I have an accounting program specifically tailored to the IT industry, its called Fincon (exe based). It basically works on a client to server directory base system. the server is currently running on a windows 7 machine with a NTFS partition. I have installed Wine. Have the shared Windows directory mounted with what I assume is the correct command for such being (mount -tsmbfs //servername/sharedir /mnt/fincon -0 usename=username,password=password). I can see the shared dir although it does take a bit long to access it on the Ubuntu machine via the mapped directory but instant via normal network browsing. I have also set up the mapped directory to my D: drive in Wine and have pointed the fincon.ini to read server field from D: directly. Here's my issue, it seems that for some odd reason I cant write to the mapped directory from Ubuntu, yet I can with my Windows machines, the permissions are set correct on the Windows 7 share and I really dunno what I'm missing. I'm quite a Linux noob just switched yesterday. Thanks guys for any help in this would be quite appreciated. As I'm pulling out my hair here and really want to migrate my work PCs to a Linux OS as it just gives less issues than Windows does ever.

  • Pantheon Not Completely Installed?

    - by Simon
    I have just installed the pantheon shell today, and I have not found any help with this yet. I am not just a random noob, i use a bunch of other shells and i also have a few development applications on my copy of ubuntu. But ever since ive opened up pantheon, i cannot find settings or this thing called the launchpad. (if the launchpad is the app drawer up in the upper left corner, or if its the dock. i have it, if thats not what launchpad is, then i cant access it.) I can only change my wallpaper by going back to unity, gnome, or KDE. There is a system settings in the power menu (upper right), but it only has Language Support, Ubuntu One, Additional Drivers, And Printing. I can still access the full ubuntu settings in GNOME of Unity. But thats it. I installed in the terminal, uninstalled, and reinstalled using the software center. Please Help Me If Any Of You Can! Thanks!!!

  • Can I replace my notebook's fan without replacing the heat sink?

    - by kuzzooroo
    My laptop (Acer Travelmate 8204) has started making a grinding noise, which seems to be coming from the fan (not the hard drive). Some articles online mention replacing the fan, but others imply that one should replace both the fan and the heat sink. Does it make sense to replace the fan only? (addendum: does this procedure really take 3 hours for a noob, as this video implies? UPDATE: the fan certainly seems to be on the "top" layer when I open my laptop but some parts of it extend under other layers) Some additional info in response to comments: I have run MS scandisk on the hard drive a few times since the grinding started. It usually reports finding something or other but the computer's behavior doesn't change I'm pretty sure it's the fan based on where the noise is coming from. I employed the cardboard tube trick from the PC World article.

  • WGet from one site on a server to another site on the same server

    - by JoshReedSchramm
    Hey all, I've recently been asked to administer a couple ubuntu boxes running web servers. I'm a dev by trade so if this question is fairly noob please forgive. We have about a dozen sites running on this box. 2 of our sites need to talk back and forth over a restful api. Unfortunately we are having issues with the sited connection to each other via wget. When we try and run wget manually from the command line from the server pointing to a site also on that server it hangs and eventually times out. If we do the same thing from outside the server to the same site on the server it works. Is there something that could be preventing sites on the same server from communicating with each other? The same thing happens pinging the site from the server.

  • How to join the World of Programming? [closed]

    - by litebread
    Name's Vlad and I am currently on my third year of Community College, studying Computer Science with emphasis on Programming in C++ and Networking. I have completed a few programming courses with general ease, but have not gained advanced understanding of programming through school. None of my friends are serious programmers working in the industry. Being an active lurker on many programming websites, and in general tech oriented sites I have noticed how little I know about the industry, the lingo and terminology. (I have no clue how Git hub works, but I generally understand what its for). So I am looking for help as to where I should look for information on the programming world and the industry in which I a very interested. By that I mean, what sites I should utilize to gain information on programming practices, introduction to advanced C++ and resources that simply introduce a 20some programming noob. I like programming, but I haven't dug my hands deep into it yet, I want to start to do so before I transfer to a University. All in all, where do I find information on becoming an actual programmer (Information that lays out a path). Thank you for reading. Have a great day!

  • Data architecture for event log metrics?

    - by elliot42
    My service has a large ongoing number of user events, and we would like to do things like "count occurrence of event type T since date D." We are trying to make two basic decisions: What to store? Storing every event vs. only storing aggregates (Event log style) log every event and count them later, vs. (Time-series style) store a single aggregated "count of event E for date D" for every day Where to store the data In a relational database (particularly MySQL) In a non-relational (NoSQL) database In flat log files (collected centrally over the network via syslog-ng) What is standard practice / where can I read more about comparing the different types of systems? Additional details: The total event stream is large, potentially hundreds of thousands of entries per day But our current need is only to count certain types of events within it We don't necessarily need real-time access to the raw data or aggregation results IMHO, "log all events to files, crawl them at a later time to filter and aggregate the stream" is a pretty standard UNIX Way, but my Rails-y compatriots seem to think that nothing is real unless it's in MySQL.

  • Installing RVM on 11.10

    - by Guided33
    I have been trying to get RVM properly installed on my system for 10 hours. The problem is, that when ever I run the command to download the install script I get this: edu@edu-VirtualBox:~$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) mkdir: cannot create directory `/usr/share/ruby-rvm': Permission denied If I run the command with sudo, I can get it installed, but then that leads to a whole host of other issues. Every tutorial I read says that you should not be installing rvm with sudo for a single user install. Why can I seem to get it installed without running sudo?

  • Pages partially load on rapid refresh

    - by user101570
    I recently set up a VPS slice with 256MB to run a LAMP stack (Ubuntu 11.04, Apache2, Mysql, PHP5). So far I'm only running a simple Wordpress site on an IP-based virtual host I set up. The performance is excellent, but I've noticed that if I send multiple HTTP requests from the same IP in a short time period, only partial pages are rendered. Then if I wait a bit and refresh the page, the entire page loads again. I noticed this behaviour when accessing the site from two browsers from my office desktop, but it also presents itself if I quickly navigate the site from a single browser (any browser). I'm guessing this is an Apache phenomenon, as the pages are rendered correctly except under the conditions above, but perhaps I'm wrong here. Could it be my hosting company with some kind of DOS protection in place? As a relative Linux/server noob, I'd really appreciate any insight into what settings in Apache could explain this behaviour, and how I might go about changing it.

  • python factory function best practices

    - by Jason S
    Suppose I have a file foo.py containing a class Foo: class Foo(object): def __init__(self, data): ... Now I want to add a function that creates a Foo object in a certain way from raw source data. Should I put it as a static method in Foo or as another separate function? class Foo(object): def __init__(self, data): ... # option 1: @staticmethod def fromSourceData(sourceData): return Foo(processData(sourceData)) # option 2: def makeFoo(sourceData): return Foo(processData(sourceData)) I don't know whether it's more important to be convenient for users: foo1 = foo.makeFoo(sourceData) or whether it's more important to maintain clear coupling between the method and the class: foo1 = foo.Foo.fromSourceData(sourceData)

  • Animating sprites in HTML5 canvas

    - by fnx
    I'm creating a 2D platformer game with HTML5 canvas and javascript. I'm having a bit of a struggle with animations. Currently I animate by getting preloaded images from an array, and the code is really simple, in player.update() I call a function that does this: var animLength = this.animations[id].length; this.counter++; this.counter %= 3; if (this.counter == 2) this.spriteCounter++; this.spriteCounter %= animLength; return this.animations[id][this.spriteCounter]; There are a couple of problems with this one: When the player does 2 actions that require animating at the same time, animation speed doubles. Apparently this.counter++ is working twice at the same time. I imagine that if I start animating multiple sprites with this, the animation speed will multiply by the amount of sprites. Other issue is that I couldn't make the animation run only once instead of looping while key is held down. Someone told me that I should create a function Animation(animation id, isLooped boolean) and the use something like player.sprite = new Animation("explode", false) but I don't know how to make it work. Yes I'm a noob... :)

  • Shifting from XNA/C# to C++?

    - by Fat_Scout
    For a while now, I've been working with XNA for game design and development (although only for personal use ATM.) Overall, I'm a major fan of XNA itself, and it's overall "feel." However, due to the fact that: XNA seems to have a lack of support (no Metro support, no updates since 2010, etc.) I plan to try and get a job in the game development industry, and due to C++'s dominance, being more familiar with it would be very useful XNA only supports Windows (non-Metro) and Xbox 360, while I am interested in Mac and (to a lesser extent) Linux support. I've been trying to shift over to C++ as my main language. However, I do not want to focus on learning raw DirectX/C++ at this time, so I've been looking for a higher level C++ API (something about the same level as XNA, although something a bit more low-level would be fine) with a feel similar to XNA. So, for someone switching from C#/XNA to C++, what would my best choice(s) be for API's similar to XNA, although unmanaged and running on C++?

  • Headphones not working in ubuntu 12.04LTS

    - by mursalat
    So after a million warnings about not supported ubuntu OS, last night I finally upgraded to 12.04 - went somewhat smoothly (sadly) After my installation I got all excited with the exciting new look when I login, and all the new shebang, gently I installed chrome and went to youtube to check out some of my music and test flash in the process, now the sound worked awesomely, however when I plugged in my headphones, I could hear only a buzz-like sound when the base drops or there is a loud noise, maybe I didn't hear it from the headphones, but some other source. However sadly my headphones are not working, and I am a noob at fixing these stuff on Ubuntu. I've done loads of programming but when it comes to linux drivers and settings I seem to get frustrated. So I would really appreciate any help people! IN SUMMARY: My headphones are not working, my laptop's internal speakers are working awesome. To be as helpful as I can I have pasted the output from lspci -v to http://pastebin.com/VQNzDkZs I have also checked the volume levels from alsamixer and none are on mute. If you need any more information, please just ask, and I will be checking this post every 3 to 4 hours! Cheers!

  • /dev/sda1 100% Mysql to blame?

Which "very simple" video editor could I use? Thanks!

  • Scp only a specific folder

    - by Ben
    Some command line syntax I don't know how to set, am a noob sometimes, sorry is that's obvious Let's says I have the following path for all my assets : /var/www/site/system/images/{image_id}/{format}/{file}.{extension} Inside the {image_id} folder, I have multiple formats (original, medium, thumb, etc...). I only want to import the /var/www/site/system/images/{image_id}/original folder, and keep the structure locally scp -r username@server:/var/www/site/system/images/*/original ~/Site/site/system/images This one does get it all, but all the files end up in the same and unique folder, no structure. I'd like to keep the structure. Is there something to do for it ?

  • Is there any CSS selector to reach an element outside of the current container?

    - by acidrums4
    (And excuse me for my bad english, for starters...) Sorry if this is a noob question, but I really don't know if the following is possible. I'm doing a html5 portfolio. I'm following a tuto from codrops to visually filter works with only css3 (http://tympanus.net/codrops/2012/01/09/filter-functionality-with-css3/). There, user can select which category want to see with some <input type="radio">'s. But those selectors are under the same container (a <section>) and give visibility for the elements via CSS using a general sibling combinator (~). So in that example, the CSS code goes like this: .ff-container input.ff-selector-type-all:checked ~ label.ff-label-type-all, .ff-container input.ff-selector-type-1:checked ~ label.ff-label-type-1, .ff-container input.ff-selector-type-2:checked ~ label.ff-label-type-2, .ff-container input.ff-selector-type-3:checked ~ label.ff-label-type-3{ background: linear-gradient(top, #646d93 0%,#7c87ad 100%); color: #424d71; text-shadow: 0px 1px 1px rgba(255,255,255,0.3); box-shadow: 0px 0px 0px 1px #40496e, 0 1px 2px rgba(0,0,0,0.1) inset; } The thing is I want to put those <input type="radio">'s on the <head> section of my portfolio, but obviously the ~ selector won't work there. So my question is that is there any selector, hack or something that can do that? Something like .ff-container input.ff-selector-type-all:checked $ header > label.ff-label-type-all { awesomeness:100%; } I really don't want to use Javascript/Jquery for that... Thank you so much in advance!

  • External monitor on old Dell 700m?

    - by Adam Henne
    Okay, linux noob. I installed 10.04 on an old Dell 700m in hopes of using it as a media center device. That seems to work great, except now it won't output to the external monitor. VGA cable works fine, TV recognizes other computers fine, it's the laptop that won't output. Turns out that the 700m, unlike every other computer out there, doesn't have a Fn hotkey to switch monitors. The only way to do it in Windows was to go through the Control Panel. In Ubuntu, though, the Monitor setup won't detect or recognize any monitors. The laptop display works fine, but I can't adjust or add anything. I did a little research and found suggestions for older Ubuntu builds involving the xorg.conf. I tried one out, in spite of my unfamiliarity, and it's screwed the whole display big time. I can fix that with a clean reinstall, that's no problem, but I'm cautious about editing xorg again. Any suggestions? Thank you!

  • Windows Recovery from Grub messed up my computer?

    - by Hudson Worden
    Ok so I'm a noob when it comes to Operating Systems and I think I really messed up this time. So I have a laptop that dual boots Windows 7 and Linux Mint 11. I was trying to boot into Windows 7 but it would just have a black screen with a blinking cursor. So I turned off my computer and tried again. Still a black screen with a cursor. So I thought "well it must be broken somehow and I remembered seeing something like 'Windows Recovery' from the boot menu so I should try it." So when I turned on my computer a third time I selected 'Windows Recovery' (Something like that I can't remember exactly what it was called). After I had selected that I got a white Windows window that said in big red letters "ERROR". I turned off my computer again a turned it back on expecting the Grub menu to reappear. I was wrong. Instead I am greeted with error: no such partition grub rescue. Then I put in a live CD for ubuntu 11.04 and tried looking at my partitions using the disk manager. Looking at my partitions I notice that there isn't a Linux partition anymore and in its place is a unallocated space partition yet the Linux Swap partition is still there. My windows partition is still fine and I can access the files in it. If you understand what has happened, is there anyway I can get my files back? I don't care about reinstalling the OS again. I just want those files that are in the Linux Mint partition.
