• make my Ubuntu 12.04 laptop visible on the network

  - by Andrew Boyd

  I'm ecstatically happy with my 12.04 on my laptop after loading it over my MS Vista... but there's just one thing, one little fly in the ointment.... While I can view our 2 Terabyte, shared hard-drive in the lounge (and copy files back and forth) I can't see my PC (when I boot up in Ubuntu 12.04) nor the Lubuntu computer connected to the TV (for movies, Youtube etc). Printing to the HP office jet on the PC doesnt work over the network either. Have had one dubious flirtation with Samba, which seems to be the only thing I've found that will 'work', however halfway through that "installation" everything just ground to a halt, the directions began to stop making sense... I was working from this page. Our Network consists of the following: Our Internet service is wirelessly sent to us from our provider to our dish on a pole. It comes into the house via an ethernet cable. We split it there to a phone, and to 6 other destinations (bedrooms, computers, and to another splitter in the lounge which has a wifi antennae and 4 ethernet ports). one port goes to the Lubuntu OS PC which is connected to the TV the second port goes to the 2 Terabyte harddrive (MS powered 'Mybooklive') (the other two are empty) My Ubuntu 12.04 laptop connects wirelessly to this splitter in the lounge. I know just enough about computers to get myself into an awful mess without too much trouble We usually can view friends' laptops when they get on our network (as they are invariably MS OS's) Our flatmate, who introduced us to Linux's computer is also invisible How can we make our Linux OS based computers visible on the network and share files and printing?

• Why do computers get slower over time? [closed]

  - by Paperflyer

  Possible Duplicate: Why does hardware get slower with time? You probably know this: A newly bought computer is snappy and responsive and just really fast. Then you use it for a couple of months and slowly but steadily the computer gets slower. Opening programs now takes a long time, accessing files takes longer, everything just takes longer than it used to. If you wipe your hard drive and reinstall, everything is back to its original snappyness, but will deteriorate again. This always happend with any operating system I used. Worst of all Windows XP, but also with Ubuntu Linux, Fedora Linux, OSX 10.5/10.6, Windows Vista... (haven't used Win 7 long enough to confirm this) Do you know the reason for this? Or even, a cure?

• Best way to keep configuration for server reinstallation?

  - by Gunnar

  I have a server at home running Ubuntu 12.04 which has grown messy over the years. I have fiddled with various packages, desktop environments (for VNC) etc. and I would like to reinstall it to start again, and have better control over what goes into the box. But I want to keep much of the configurations after reinstallation, like LVM configuration, apache2, samba, etc etc. There would ideally exist a program which could analyze /etc, installed packages and such, store the information, and selectively put it back into the new installation. I am even considering installing Ubuntu server on a virtual machine, just to be able to compare the contents of /etc with a clean installation, and even perform a migration to the virtual machine first, to verify that the transfer process works. How do one go about performing this kind of reinstallation? Have anyone seen any resources on the net on the topic?

• Will a polled event system cause lag for a server?

  - by Milo

  I'm using a library called ENet. It is a reliable UDP library. The way it works is a polled event system like this: ENetEvent event; /* Wait up to 1000 milliseconds for an event. */ while (enet_host_service (client, & event, 1000) > 0) { switch (event.type) { case ENET_EVENT_TYPE_CONNECT: printf ("A new client connected from %x:%u.\n", event.peer -> address.host, event.peer -> address.port); /* Store any relevant client information here. */ event.peer -> data = "Client information"; break; case ENET_EVENT_TYPE_RECEIVE: printf ("A packet of length %u containing %s was received from %s on channel %u.\n", event.packet -> dataLength, event.packet -> data, event.peer -> data, event.channelID); /* Clean up the packet now that we're done using it. */ enet_packet_destroy (event.packet); break; case ENET_EVENT_TYPE_DISCONNECT: printf ("%s disconected.\n", event.peer -> data); /* Reset the peer's client information. */ event.peer -> data = NULL; } } It waits up to 1000 milliseconds for an event. If I'm hosting say 75 event driven card games and a lobby on the same thread as this code, will it cause any problems. If my understanding is correct, the process will simply sleep until there is an event, when there is one, it will process the event then come back here where potentially 5 or so events have queued up since so enet_host_services would return right away and not cause lag. I have been advised not to use multiple threads, will that be alright like this? Thanks

• How do I use depth testing and texture transparency together in my 2.5D world?

  - by nbolton

  Note: I've already found an answer (which I will post after this question) - I was just wondering if I was doing it right, or if there is a better way. I'm making a "2.5D" isometric game using OpenGL ES (JOGL). By "2.5D", I mean that the world is 3D, but it is rendered using 2D isometric tiles. The original problem I had to solve was that my textures had to be rendered in order (from back to front), so that the tiles overlapped properly to create the proper effect. After some reading, I quickly realised that this is the "old hat" 2D approach. This became difficult to do efficiently, since the 3D world can be modified by the player (so stuff can appear anywhere in 3D space) - so it seemed logical that I take advantage of the depth buffer. This meant that I didn't have to worry about rendering stuff in the correct order. However, I faced a problem. If you use GL_DEPTH_TEST and GL_BLEND together, it creates an effect where objects are blended with the background before they are "sorted" by z order (meaning that you get a weird kind of overlap where the transparency should be). Here's some pseudo code that should illustrate the problem (incidentally, I'm using libgdx for Android). create() { // ... // some other code here // ... Gdx.gl.glEnable(GL10.GL_DEPTH_TEST); Gdx.gl.glEnable(GL10.GL_BLEND); } render() { Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); Gdx.gl.glBlendFunc(GL10.GL_SRC_ALPHA, GL10.GL_ONE_MINUS_SRC_ALPHA); // ... // bind texture and create vertices // ... } So the question is: How do I solve the transparency overlap problem?

• How to configure bind9 to route to host's IP

  - by Greg

  I'm running apache and bind9 on the same server. I would like to set a master zone to route back to this very machine's IP address without explicitly specifying it. Is this possible? If I use 127.0.0.1 for the A record, then when another computer on the network does an nslookup for mydomain.local, bind of course just returns the loopback ip (127.0.0.1) -- not the IP of the server. Is there to way to tell it to just return the network IP address for the server itself, as defined in /etc/network/interfaces?

• setting up delegate or smtp forwarding

  - by cotiso

  for work we have a remote dedicated server to run our webservice that also runs our email services, at home(comcast residential internet) i cannot send mail using the dedicated server's SMTP, comcast spits back a error saying i can only use their SMTP server for sending mail at work(comcast business internet) we can use our dedicated server for sending mail with no problem so i set up a box at work to forward smtp traffic, i'm new to all this networking stuff by the way i used delegate to forward smtp traffic, can someone point me in the right direction on how to use this program(delegate) to fix our issue the delegate command i used to test is : delegated -P25 SERVER="smtp://dedicated.server.com:25" PERMIT=":::" -v i also opened up port 25 on the router so it points to my boxes ip are there any other ways to fool comcast into thinking im using my works ip to send mail, my coworkers and i are unable to send mail from home for some time now thanks

• Daily Blog Archives and Duplicate Content

  - by nemmy

  A few weeks back I realised that my blog software was creating daily post archives. Which basically resulted in duplicate content especially if I only had one post a day. The situation is something like this: www.sitename.com/blog/archives/2013/06/01 - daily archive for 1 June 2013 www.sitename.com/blog/archives/2013/06/my-post-name.html So, here we have two pages that are basically identical except the daily archive has some meaningless title like "Daily Archive for 1 June 2003". And I have no control over which content Google decides is the primary content. It's quite possible (and likely) that the daily archive could be the "primary" content and the actual post itself the "duplicate". Once I realised it was doing this I modified the daily archive template to include <meta name="robots" content="noindex"> Here we are a few weeks later and I still see some daily archives coming up in Google search results. I realise some of those deep pages might not be crawled yet but I am worried that the original post (which should be the PRIMARY content) has been marked duplicate content by Google. Now I've no indexed the daily archives I might end up with no indexed content AND the original articles still flagged as duplicates. And nothing will show up in search at all. Have I screwed myself here or is there a way out?

• OVM Server for SPARC Enhancements

  - by Owen Allen

  Oracle VM Servers for SPARC saw a few improvements in Ops Center 12.2. In addition to brownfield support, we've made a number of enhancements to let you add OVM Servers for SPARC to a Server Pool and enable migration of their guests. -When you discover an OVMSS Control Domain and manage it with an Ops Center Agent, its guests are automatically discovered as well. The guest metadata is initially put in the local metadata library in the /guests directory, but you can move it from one library to another to enable migration.-Once you've discovered an OVMSS control domain, you can add it to a server pool, even if it's already configured and running logical domains. Even if live migration between OVMSS systems isn't possible due to CPU incompatibilities, you can still put them in a server pool together and enable guest recovery by configuring the CPU architecture of the guest domain as generic. -You can mark a guest's storage as shared to indicate that it's available to other managed OVM Server systems with the same back-end name. This lets you use storage not fully managed in an Ops Center library as part of guest migration. Put together, these enhancements make it much easier to manage and maintain OVMSS guests.

• How to fix boot and mount failed drops to initramfs prompt in Ubuntu 12.04?

  - by msPeachy

  Ubuntu partition does not boot. This started after a power interruption during system boot. The next time I boot, I encountered the following error message: mount: mounting /dev/disk/by-uuid/3f7f5cd9d-6ea3-4da7-b5ec-**** on /root failed: Invalid argument mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target file system doesn't have /sbin/init. No init found. Try passing init= bootarg. Busybox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _ I've searched for similar posts here and most of the recommended solution is to reboot to the Ubuntu LiveCD. That's another problem because I cannot boot to a LIVEUSB, this is the error message I get when booting to a LiveUSB: Busybox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) mount: mounting /dev/sda2 on /isodevice failed: Invalid argument Could not find the ISO /ubuntu-12.04-desktop-i386.iso. This could also happen if the file system is not clean because of an operating system crash, an interrupted boot process, an improper shutdown, or unplugging of a removable device without first unmounting or ejecting it. To fix this, simply reboot into Windows, let it fully start, log in, run 'chkdsk /r', then gracefully shut down and reboot back into Windows. After this you should be able to reboot again and resume the installation. I cannot boot into Windows because I don't have a Windows partition. Do I have to install Windows to fix this problem? Is there a way to fix this in the (initramfs) prompt? Please help. Thank you!

• GitHub: Are there external tools for managing issues list vs. project backlog

  - by DXM

  Recently I posted one of my the projects1 on GitHub and as I was exploring capabilities of the site, I noticed they have a rather decent issue tracking section. I want to use that section as a) other people can report bugs if they'd like and b) other people can see which bugs I'm aware of. However, as others have noted, issues list cannot be prioritized in order to create a project backlog. For now my backlog has been a text file, but I'd like to be able to have it integrated so the same information isn't maintained in different places. Having a fully ordered list, which is something we also practice at work, has been very useful as I can open one file, start with line 1 and fire off 2 or 3 items in one sitting without having to go back to a full issues/stories bucket. GitHub doesn't offer this. What GitHub does offer is a very nice and clean API so issues can easily be exported into anything else. I've searched to see if there are other websites (like Trello) that integrate with GitHub issues, but did not find anything. Does anyone know of such a product, service or offline tool? Those that use GitHub, what is your experience in managing backlog? I kinda hate the idea of manually managing two disconnected lists like some people seem to be doing with Wiki project pages. 1 - are shameless plugs allowed no this site? Searched but didn't find a definite answer. If it's bad practice, STOP and don't read further As a developer I got sick and tired of navigating to same set of folders 30 times a day, so I wrote a little, auto-collapsible utility that gets stuck to the desktop and allows easy access to the folders you constantly use.

• MAAS/JuJu Clarifications

  - by ectoskeleton

  I really love the concept of MAAS underlying an OpenStack implementation, but there are a few questions about MAAS that I am not entirely clear on. Should all hosts be set to network boot at all times or after they have been registered and allocated as a service, should they boot to disk? After juju bootstrap is executed, I turn on the machine that has been allocated (note WoL isn't working, I suspect it's being blocked on the network), the machine boot's up and then juju status executes correct, agent running and all that good stuff. If I 'reboot' the machine (testing power failure/problem whatever), juju status comes back but the agent-state is no longer in running state, and so far I have to destroy the environment and restart. In all cases I have never been able to deploy any services to any of the other nodes. I deploy the service with juju, note which node it was assigned, and then start the system. The system just boots up into a basic node. If I SSH to it I have to enter password, so it's not setting up the ssh key or anything. This is on Ubuntu 12.04.1 LTS systems and HP GL360G7 hosts. The MAAS management server is running as a VM but all on the same network. At this point I am not sure if I am doing something wrong or if there is a problem somewhere else. Is the idea that anytime a host is rebooted it should be rebuilt from the ground up, or is something else going on behind the scene to tell it to boot the local image. If the latter, why doesn't the agent start on a system that has been successfully setup before (juju bootstrapped system)?

• How to achieve a loosely coupled REST API but with a defined and well understood contract?

  - by BestPractices

  I am new to REST and am struggling to understand how one would properly design a REST system to both allow for loose coupling but at the same time allow a consumer of a REST API to understand the API. If, in my client code, I issue a GET request for a resource and get back XML, how do I know what to do with that xml? e.g. if it contains <fname>John</fname><lname>Smith</lname> how do I know that these refer to the concept of "first name", "last name"? Is it up to the person writing the REST API to define in documentation some place what each of the XML fields mean? What if producer of the API wants to change the implementation to be <firstname> instead of <fname>? How do they do this and notify their consumers that this change occurred? Or do the consumers just encounter the error and then look at the payload and figure out on their own that it changed? I've read in REST in Practice that using a WADL tool to create a client implementation based on the WADL (and hide the fact that you're doing a distributed call) is an "anti-pattern". But I was planning to do this-- at least then I would have a statically typed API call that, if it changed, I would know at compile time and not at run time. Why is this a bad thing to generate client code based on a WADL? And how do I know what to do with the links that returned in the response of a POST to a REST API? What defines this contract and gives true meaning to what each link will do? Please help! I dont understand how to go from statically-typed or even SOAP/RPC to REST!

• Make Thunderbird3 not switch to firefox after clicking a link

  - by WebDevHobo

  Using ThunderBird 3 on Windows 7. When I get a mail with a link, I usually click it, if I know what it's about. Sadly, Thunderbird switches to Firefox which is opening the new tab. I'm active on several forums and get several of these messages per day. I don't want to click a link, be forced into firefox, go back to thunderbird, click a link, be forced into Firefox, etc... Is there an option to disable this? If not, I can see myself quitting Thunderbird altogheter and simply using web-based email checking instead of using an app.

• Alt-Escape has different effect on different Win-XP machines

  - by Ram Rachum

  This is really weird. On my desktop computer, I often use Alt-Escape to send the active window to the background. This is really useful for window management. However, when I try pressing Alt-Escape on my new laptop, it does something similar but not identical: It sends the active window back, but not all the way to the background. i.e., instead of giving it the lowest index number, it just decrements its index number, probably by 1. Both computers have the same Windows XP Professional. Why is this? And how can I make my laptop computer send the active window to the background instead?

• How to define type-specific scripts when using a 'type object' programming pattern?

  - by Erik

  I am in the process of creating a game engine written in C++, using the C/C++ SQLite interface to achieve a 'type object' pattern. The process is largely similar to what is outlined here (Thank you Bob Nystrom for the great resource!). I have a generally defined Entity class that when a new object is created, data is taken from a SQLite database and then is pushed back into a pointer vector, which is then iterated through, calling update() for each object. All the ints, floats, strings are loaded in fine, but the script() member of Entity is proving an issue. It's not much fun having a bunch of stationary objects laying around my gameworld. The only solutions I've come up with so far are: Create a monolithic EntityScript class with member functions encompassing all game AI and then calling the corresponding script when iterating through the Entity vector. (Not ideal) Create bindings between C++ and a scripting language. This would seem to get the job done, but it feels like implementing this (given the potential memory overhead) and learning a new language is overkill for a small team (2-3 people) that know the entirety of the existing game engine. Can you suggest any possible alternatives? My ideal situation would be that to add content to the game, one would simply add a script file to the appropriate directory and append the SQLite database with all the object data. All that is required is to have a variety of integers and floats passed between both the engine and the script file.

• Not booting from USB or CD (SYSLINUX Message)

  - by Raymond

  I am trying to install linux on my laptop, a Toshiba Satellite C6550-S5200. I did it once but something happened so I removed it then I had to destroy all data on hard drive so now I have nothing on it. Well I got a iso file burned to a CD and to a flash drive. With the flash drive I get. SYSLINUX 4.06 EDD 4.06-pre7 Copyright (C) 1994-2012 H. Peter Anvin et al With the CD it will start booting it but somewhere loading it up, the dots turn all orange and stay that way and my CD drive turns quiet. Oh and some more info the images work because I tried loading them up on another pc and it worked just fine. I manage to get the CD to boot I just had to let me pc boot up first then insert the CD and have it boot the CD then. Once I get done installing ubuntu it works fine but I have to leave the PC on 24/7 for if I turn it off the PC will freeze 5-10 seconds after booting back up no matter how I install it.

• Unity Launcher only runs once - requires lightdm restart before it runs again

  - by Don

  I have an intermittent problem that just started showing up several days ago. I am running 11.10 and all updates are current. I first saw the symptom with a custom version of the "Home" nautilus-home.desktop file I created in ~/.local.share/applications. I added a few static shortcuts to specific folders. What I found was, clikcing the icon once would open up my home folder, but after closing that nautilus window, clicking the icon again did nothing (did not even show icon backlight animation). However, I could right click on the same icon and access my short cuts as many times as I want. Symptom persisted until restarting lightdm. Just yesterday I saw the same sort of symptom happen with a custom launcher I created for a chromium-borwser to open a specific URL (with a few short cuts to other URLs). Click the icon - it works once. Then never again. Right click the icon and I can use the short cuts over and over - no problem. Note - at one point I assumed I might have a problem with my custom .desktop file, so I did a test by removing my custom nautilus-home.desktop. However, even after restarting lightdm, and verifying the home icon was the standard one from /opt/share/applications (all my custom shortcuts were gone) I saw the same symptom re-appear - it runs once and then not again until restarting lightdm. It seems to be intermittent and seems to move between various launchers. Not sure what to do or even what background data to gather. Attempt to improve question after the first answer: I tried the following: 1) remove all custom launchers 2) reboot 3) add custom lauchers back 4) reboot 5) attempt to use .... still have "runs once and never again" symptom with several launchers

  I have a really strange problem here. I have a Asus Zenbook Prime running Windows 7. Whenever I put it to sleep and I have Pandora open (but paused) in my web browser, several hours later the computer turns itself back on and Pandora will unpause itself and start playing. (More often than not this happens at 3AM in the morning so I am less than pleased.) What the heck is going on here? I've never even heard of this happening before...

• Using unordered_multimap as entity and component storage

  - by natebot13

  The Setup I've made a few games (more like animations) using the Object Oriented method with base classes for objects that extend them, and objects that extend those, and found I couldn't wrap my head around expanding that system to larger game ideas. So I did some research and discovered the Entity-Component system of designing games. I really like the idea, and thoroughly understood the usefulness of it after reading Byte54's perfect answer here: Role of systems in entity systems architecture. With that said, I have decided to create my current game idea using the described Entity-Component system. Having basic knowledge of C++, and SFML, I would like to implement the backbone of this entity component system using an unordered_multimap without classes for the entities themselves. Here's the idea: An unordered_mulitmap stores entity IDs as the lookup term, while the value is an inherited Component object. Examlpe: ____________________________ |ID |Component | ---------------------------- |0 |Movable | |0 |Accelable | |0 |Renderable | |1 |Movable | |1 |Renderable | |2 |Renderable | ---------------------------- So, according to this map of objects, the entity with ID 0 has three components: Movable, Accelable, and Renderable. These component objects store the entity specific data, such as the location, the acceleration, and render flags. The entity is simply and ID, with the components attached to that ID describing its attributes. Problem I want to store the component objects within the map, allowing the map have full ownership of the components. The problem I'm having, is I don't quite understand enough about pointers, shared pointers, and references in order to get that set up. How can I go about initializing these components, with their various member variables, within the unordered_multimap? Can the base component class take on the member variables of its child classes, when defining the map as unordered_multimap<int, component>? Requirements I need a system to be able to grab an entity, with all of its' attached components, and access members from the components in order to do the necessary calculations and reassignments for position, velocity, etc. Need a clarification? Post a comment with your concerns and I will gladly edit or comment back! Thanks in advance! natebot13

• Computer science curriculum for non-CS major?

  - by Daniel

  Hi all, I would like to have some ideas for building up my foundation CS skills. I have started programming computers 10 years ago and have made a pretty good career out of it. However, I cannot stop thinking that the path that brought me here was very particular, and if something goes wrong (e.g. I get laid off) it would be harder to find a job here in the US on the same salary level, OR in a top company. The reason I say that is that I am a self-learner; my degree is not in Computer Science so although I master C/C++/Java, I do not have the formal CS and mathematical background that many other software developers (esp. here in the US) have. When I look at job interview questions from Apple, Google, Amazon, I have the impression that I'd flunk those technical interviews at some point. Don't get me wrong, I know my algorithms and data structures, but when things dive too deeply into the CS realm I am in trouble. What can I do to close the gap? I was thinking about a MSc in CS, but will I even UNDERSTAND what's going on there if I'm not a CS undergrad? Should I go back to basics and get a BSc in CS instead? I always tend to go into self-study mode when I want to learn new stuff, but I have the impression that I will need more formal education in CS if I want to have a shot at working at those kinds of companies. Thank you!

• How to recover bad encripted directory

  - by Fato Alessandro

  I had a problem while formatting Ubuntu. I tried to reinstall without formatting the home directory and with the same username. The home directory of the new installation was set to be encrypted. Then the installation went wrong because of the cd. So it really never started (stopped at coping stage). How ever Ubuntu did encrypted the home directory but probably the procedure went wrong. By now I installed Ubuntu in another partition, tried to mount with encrypted-recovery but the mounted directory in tmp wasn't the directory I had before. There were just strange directories with coded name. Strange fact is that the file system is not damaged: it continues to know how much data is actually stored in it. If I look with gparted or even nautilus I see 45 Gb of data present on the partition. This let me think that my data are not erased but maybe hidden. Moreover when I tried to mount the encrypted home directory with encrypted-recovery-personal it asked me the encryption secret. I insert nothing, just pressed enter, and the password was accepted. Is thre a method for removing my data? Maybe trying to rencrypt the directory? How could I get back to the previous documents. Thanks to everyone

• Can one build a single disk RAID 1 array?
