  • What exactly is a chroot? Is it similar to a simultaneous dual boot?

    - by mathematician1975
    It has been suggested to me that the use of a chroot might solve my problem of building an application that must run on an embedded device. I have inferred from this description that it is somehow similar to creating the embedded environment locally on my machine which I can then use to develop on from my desktop development machine. Is this the right way to look at the functionality or have I totally misunderstood? In order to get some idea of how it works I read this https://wiki.ubuntu.com/DebootstrapChroot which I will attempt to make a chroot for an old Ubuntu version on my machine. However, as I am a total linux novice, I am a bit concerned that as I do not entirely know what I am doing is there anyway that I could end up with an unusable system?? Is this something that a novice should even attempt???

  • Can not export JARS in lwjgl!

    - by NerdyLegend
    I did it before but for some reason it's doing the stupid problem again. I want to export as a regular Jar file, not a folder full of files. I export it like in Oskar Veerhoak. cmd says Exception in thread "main" java.lang.RuntimeException: Resource not found: res/F lubberFlap.png at org.newdawn.slick.util.ResourceLoader.getResourceAsStream(ResourceLoa der.java:69) at com_FlubberSpace.MainFS.main(MainFS.java:118) I tested it out with my other project with the same code pretty much. This is how I load my Textures wood = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("res/wood.png")); of course it works fine in eclipse but not after export. I havn't tried giving the previous game its' own project, I have it in a package. Can someone record how to export properly? I want a jar file that you just double click to start it. I also want it so nobody can extract the files and see my classes and res.

  • Possibility Program for number of pieces

    - by Brad
    I would like to put a program together to calculate the number of 60' pieces would be needed from a list of shorter pieces. For example, I sell rebar cut to length from our standard length of 60'-0". Now the length the customer requires are as follows: 343 pc @ 12.5' 35 pc @ 13' 10 pc @ 15' 63 pc @ 15.5'....... There are 56 total lengths ranging from 12.5' to 30.58' The idea is to limit the amount of waste from the 60' piece. The input from the user would be: number of differnt lengths Length of piece to cut from count of different lengths The result would be the number of prime pieces needed to fulfill the order. What well-known algorithms exist that could help me solve this problem?

  • 12.10 Unity GUI Not Displaying

    - by lolajl
    I had 12.04 installed and had no problems at all, having had it setup on my Compaq Presario CQ62 for about 2 weeks (I'm new to Ubuntu and I had a spare laptop to experiment with). Last night, I installed 12.10 through the update manager. Now, I'm not seeing the Unity GUI if I select Default or Ubuntu, at all, just the Eclipse launcher which I had created sitting on the desktop. Even hitting the Windows key to bring up Dash doesn't work. But, when I select GNOME during login, I'm able to access everything in the GUI, including the menu folders for games, internet, system settings, etc. There was a couple error message saying that a system file wasn't loading properly but I forgot to write these down, and now these error messages aren't loading when I restart. Will I need to wipe clean and reinstall?

  • How to create a Request Specific Thread Safe Static int Counter?

    - by user960567
    In one of my server application I have a class that look like, class A { static int _value = 0; void DoSomething() { // a request start here _value = 0; _value++; // a request end here } // This method can be called many time during request void SomeAsyncMethods() { _value++; } } The problem is SomeAsyncMethods is async. Can be called many times. What I need when a request start set _value = 0 and then asynchrosnously increment this. After end of request I need the total. But the problem is that another request at the same time can access the class.

  • Why don't my Google Analytics custom segmentation visit numbers match up?

    - by Hates_
    I have three main areas of my site and want to track total usage as well as breakdowns of the three parts. I am trying to segment the "type" of use on each page using a custom variable as such: ['_setCustomVar',1,'Visitor Type','Unknown',1] Visitor type can be one of three values: "Unknown", "Reader" or "publisher". Every page has this value set. Now when I look at my analytics chart and chose all three segments, the individual values do not match the sum. I've double checked the pages to make sure the custom var is there.

  • count specific values in a multidimensional array

    - by user1680701
    I have an odd set of arrays that I need to count how many times specific values show in the results. Currently I have this bit of code. $nested_arrays = shopp_orders( '2011-11-30 00:00:00', '2012-11-30 12:59:59', false, '', 2 ); print_r($nested_arrays); This code pulls multiple arrays (serialized

I tried the following but it only counted the 2 large arrays. function count_nested_array_keys(array &$a, array &$res=array()) { $i = 0; foreach ($a as $key=>$value) { if (is_array($value)) { $i += count_nested_array_keys($value, &$res); } else { if(!isset($res[$key])) $res[$key] = 0; $res[$key]++; $i++; } } return $i; } $total_item_count = count_nested_array_keys($nested_arrays, $count_per_key); echo "count per key: ", print_r($count_per_key), "\n"; If someone could show me how to count how many times each state value occurs, example, VA = 2 NC = 1 I can take it from there.

  • Renaming site, moving domain after 3 yrs. Should I reconsider?

    - by user6162
    After recently announcing it, one of my readers with a background in website management sent me an email saying that I should reconsider moving my domain from [keyword]news.org to [same keyword]lab.com. It is a content-heavy news site around products that I hope to eventually build into a more comprehensive authority for the [keyword] industry I'm covering w/ B2B services, merchandise, etc. The current domain is a bit generic & I think the new one will be more marketable. Relevant stats: 320k-350k pv's/month Google brings in 39% and Yahoo/Bing 4% of traffic 10-11% of monthly search strings contains " news" SEOMoz Open Site Explorer stats: Page authority: 65/100 Domain authority: 58/100 Linking root domains: 226 Total links: 35,700 I am familiar with what I need to do as far as 301 redirects, etc. I was assuming that I'd be ok after following Google's recommended procedures but now I am not so sure.

  • How can I make these Google Analytics numbers add up? (Frequency & Recency)

    - by Joe
    Here's a screen shot from Google Analytics. It's my last months traffic, and this is the 'Frequency & Recency' tab. So I believe that if I add up all the numbers under 'visits' I get 11,432, which is right, and if I add up all the numbers under 'pageviews' I get 14,785 and that's right as well. But, let's take the last line - the last line appears to say that 71 people, visited more than 51 times each, and they viewed a total of 243 pages between them - that doesn't seam to make any sense - did they view 9% of a page each time? So that's clearly wrong - what's the error in my calculation?

  • Les éditeurs de solutions de sécurité devraient-ils bloquer les malwares gouvernementaux ? F-Secure pense que oui

    Les entreprises de sécurité informatique devraient-elles bloquer les malwares gouvernementaux ? F-Secure pense que oui De récentes révélations accusent les autorités égyptiennes d'avoir acheté puis utilisé un système de surveillance allemand (FinFinder) pour espionner ses citoyens. La société qui le commercialise, Elaman, propose divers produits sous le label de "solutions de sécurité gouvernementale", comme FinSpy qui "garantit un accès total et en temps-réel ainsi que le contrôle à distance de l'ordinateur cible", ou FinFly, un "proxy infectieux utilisé pour propager des malwares intrusifs".

  • Installing purchased apps by terminal

    - by DoDoGo
    I've been trying to reinstall all my purchased apps on a new machine, and I ran into a problem. Because of the size of them (about 10-12GB in total) and the fact that downloading them is painfully slow for whatever reason (at most 800kB/s), it takes a lot of time (not to mention USC crashing). And then, when I tried to leave them overnight, none of them were installed and everything was at the same spot I left it. Is there anyway to install them via terminal? Like some kind of USC backend were I could just add the archives for apps listed as purchased and then install them via apt-get?

    My business' website suddenly started loading extremely slowly over HTTPS last night and continues through today. The facts: Page loadtime via HTTPS - 2 minutes +, HTTP - 3 seconds max. NO updates were done on any site files in the past 2 weeks. This is on Shared Hosting HTTPS has worked perfectly over the past 9 months then suddenly failed yesterday.

Tried proxies - same result. Tried 3 separate computers - same result. I'm basically at a total loss here. Does anyone know what could cause such a thing to happen? Please help guide troubleshooting.

What i am looking for is some tutorials/guides on how to begin using cocos2dx for the total beginner. Things like how to setup a project and run it and how to do simple things like draw graphics on the screen, play sounds and get input. I am running on windows 7 and have been told by the cocos2dx wiki that this may cause problems so if anyone has a solution to this that would also be helpful.

  • Where actually did they spend money? [on hold]

    - by WannabeProgrammer
    I am a total beginner in the field of game development. Every time I saw or read an interview session with any indie developer they mention about the amount of money they spend on developing a game. I want to know where exactly did they spend the money ? Just imagine that you are making a game for mobile devices from scratch , where and all will you be spending your money to make one ? Is it possible to make games for mobile devices without spending any ? If yes , then it makes more sense for a indie game developer who is talented but comes from a very weak financial background. Thank you.

  • How to clean unused app files

    - by Ando
    I've finished working on a web app and looking back at the process, I can see that a lot of extra files have been accumulated - backup css, php files, javascripts, images. I'm using an MVC workflow (codeigniter) and I would like to clean the app from unused files. There are also libraries which I've downloaded but referenced some of the files in my code, yet I've kept the unused files too. Total mess really, I'll take a note for the next app to become more organized. There is also a fair security concern regarding these sorts of situations, plus I think that it would be better to omit all the extra files when search engines are indexing the app. Has anyone been in that situation and what is the safest/fastest way to clean the app? My setup: MVC Codeigniter - Netbeans - Mac

    GNU recommend make AUTHORS file for list of authors and contributos of a program. But how many "levels" of authors and contributors should contain the file? E.g. I write a program foo, that actively use some library. Should I include authors of the library in the AUTHORS? It seems to yes, because total code of foo contain code from library. But if yes, I should include also authors of all others libraries, including standard libraries of compiler, authors of the compiler and other tools for producing final executable code, authors of OS...

  • Are my Google Analytics ( 2 domains 1 site) duplicated or unique?

    - by MarcDJay
    We have recently built a new website with a new domain to replace an old website, and on the advice of our IT guys and web dev team have pointed both oldaddress.com's & newaddress.com's a records to the new website. Now, they both share the same google analytics code (UA-12345-1) and as such we have two entries in the Google Analytics dashboard. The problem is I'm still fairly novice with GA and as the reports seem VERY similar (~25k pageviews for each domain), are these figures exclusively for that domain? For example: oldaddress.com 25,400 pageviews newaddress.com 25,600 pageviews Does this mean that in total for this website I have 51,000 pageviews. Hope this is clear enough but let me know if anything needs clarifying. Thanks.

  • C++ developer looks for book(s) about Android apps & widgets (& services etc.) [on hold]

    I'm senior C++ developer, I have also programmed professionally j2me some years. I'd like to make some apps and widgets for Android and I'd like to read up a bit on this new java stuff Android is using. I have (of course) checked out some tutorials and so but it seems I miss the basics, I can compile some stuff (read: examples) in eclipse but I just don't know how to, for example, add a service or what an 'intent' is, why my widget isn't called but successfully launches the main app when clicked and so on. So, what is a really good book for someone that is a developer but mostly need the hard facts about developing something specific like Android apps & widgets? Thanks a bunch!

  • Is asking for control totals on a file an outdated means of verifying a file?

    - by CTKeane
    I'm in a new position where I need to process a flat files on a regular basis. The last time I did this was 5 or 6 years ago but as part of the file layout I received control totals. It gave me simplistic information on the file like the total number of records as well as sums of the important fields. This helped me during testing then also during production to verify the file arrived and has correct information. I have asked for similar data for this new project and have hit a wall of no. Is this no longer a standard practice? Is there a better way?

  • In setting up dual Boot with Windows XP and Ubuntu, which OS do I install first?

    - by markl
    I'd like to install both Ubuntu 12.04 and Windows XP on a Dell laptop, and I was thinking about using a dual boot structure, and using the bulk of my hard drive as empty hard drive space to share files between the two operating systems (so choice of file system type is very important in this set-up). The kind of partitioning structure I would like to use is Partition 1 - Ubuntu 12.04 (root) (20GB) Partition 2 - Ubuntu /home (20GB) Partition 3 : Free Space (560GB) Partition 4 : Windows XP (35GB) Partition 5 : SWAP (3GB) (Total Hardrive Capacity is ~640GB) My question is; what is the best way to go about setting up this kind this system? Should I install Windows XP first and setup the partitions, and then install Ubuntu which I believe will install the GRUB bootloader for OS booting choice or Do I install Ubuntu first, setting up the available partitions and then perform a WIndows install? Please let me know if there is anything in this setup that I have left out and should know about, including things related to setting particular partitions as logical or primary, and whether the boot partition and the filesystem partition should actually be two separate partitions.

  • Creating Java EE Projects with Maven

    - by M.C.
    I've been developing Java EE web apps with Eclipse for about a year. My employer doesn't use Maven, but the more I read about it, the more convinced I am that Maven + Hudson will be greatly beneficial for us. First, though, I have to become comfortable with those technologies in my spare time, so that I can create a proof-of-concept. Right now, I'm still a Maven newbie. Is there a set of best practices for creating Java EE web apps with Maven? For example, I could create a project with a basic archetype and then add all of the necessary JARs by putting dependencies in the POM for the servlet container, EJB, EclipseLink, etc... That might work, but it might not be the best way to do it. I'd greatly appreciate any guidance that you could provide on this topic.
