• How to make VLC show single FLAC file containing many tracks as separate tracks

  - by Bryce Thomas

  I have a single .flac file that encompasses multiple tracks comprising a music album along with the corresponding .cue file. I'm running Ubuntu 10.04 with VLC player, and am trying to get VLC player to show the individual tracks and allow me to use the previous and next controls to move back and forth between tracks. The problem I'm having is that when I open the single .flac file with VLC, it just shows a single track the duration of the entire album, and I'm unable to skip back and forth between tracks. Is there any way to have VLC show the individual tracks contained within a .flac file without having to pre-split the .flac file into individual track files first?

• XNA texture stretching at extreme coordinates

  - by Shaun Hamman

  I was toying around with infinitely scrolling 2D textures using the XNA framework and came across a rather strange observation. Using the basic draw code: spriteBatch.Begin(SpriteSortMode.Deferred, null, SamplerState.PointWrap, null, null); spriteBatch.Draw(texture, Vector2.Zero, sourceRect, Color.White, 0.0f, Vector2.Zero, 2.0f, SpriteEffects.None, 1.0f); spriteBatch.End(); with a small 32x32 texture and a sourceRect defined as: sourceRect = new Rectangle(0, 0, Window.ClientBounds.Width, Window.ClientBounds.Height); I was able to scroll the texture across the window infinitely by changing the X and Y coordinates of the sourceRect. Playing with different coordinate locations, I noticed that if I made either of the coordinates too large, the texture no longer drew and was instead replaced by either a flat color or alternating bands of color. Tracing the coordinates back down, I found the following at around (0, -16,777,000): As you can see, the texture in the top half of the image is stretched vertically. My question is why is this occurring? Certainly I can do things like bind the x/y position to some low multiple of 32 to give the same effect without this occurring, so fixing it isn't an issue, but I'm curious about why this happens. My initial thought was perhaps it was overflowing the coordinate value or some such thing, but looking at a data type size chart, the next closest below is an unsigned short with a range of about 32,000, and above is an unsigned int with a range of around 2,000,000,000 so that isn't likely the cause.

• PBX with Fax and Google Voice

  - by Phill Pafford

  Looking to replace/port my home number which I use for mainly faxing for my home business to a PBX server ( Thinking Asterisk or Elastix ). My question is: Does Asterisk/Elastix support Faxing ( Incoming / Outgoing ) Does Asterisk/Elastix support Google Voice Here is what I'm looking to do: Run some sort of PBX software from my own home server that will allow me to use Google Voice for my home number, possibly allow multiple Google voice ( Though I could live with just the one ) and must support Faxing ( Incoming and Outgoing ). Would Asterisk/Elastix support all of this or would you recommend something else for this? Looking to avoid some of the pitfalls that could happen I like Ubuntu if a Linux environment is needed

• Dual Boot, Dual Hard Drives!

  - by Mars

  I'm posting this question after reading most of similar ones. My situation is different here in the fact that I'm installing on SSD and not partitioning my HDD, and that I can actually boot! I'm just looking to improve the convenience of having easier way to choose. 1- I have a Dell Inspiron 15R SE. It has HDD (1TB) and SSD (32GB). I managed to do whatever things I did in distant past to set the SSD free (I don't really care how fast my system boots). Now I wanted to install Linux on the SSD and leave the HDD untouched. It's way too precious for me to mess with it. So, I repartitioned the SSD to: 30GB for /root, 1GB for /swap, and 100MB for /boot. I installed Linux on the root and the GRUB on boot (of the SSD). Now GRUB immediately boots into linux and doesn't allow me to boot to Windows. BUT! If I enable UEFI Boot manager and choose "Windows Boot Manager" after hitting F12, I can boot into Windows 8 normally. I'd say that's pretty ok, except, I'd prefer to have the option to boot into which one or at the very least, default to boot to Windows. 2- I'm concerned that if I now delete the SSD partition, that the boot will break and I won't be able to boot anything! Does this seem like a valid concern? I made that choice of having linux on SSD because I'm going to be training on it, so I expect multiple resets from time to time.

• What is it that automatically checks config changes (such as those in /etc) into git?

  - by Brandon

  I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

• Automatically updating routing table on server

  - by bramp

  I have a LAN with three routers on it, one connected to the Internet, one VPN router connected to a few remote sites, and a final route connected to a private network (using BGP to get prefix advertisements). On the same LAN I have multiple Linux servers which needs access to the networks behind each router. I have achieved this by configuring static routes on the server, pointing the different network prefixes to the correct router. This has worked well, but every time we connect to a new remote VPN, we have to change all the servers to be aware that the network is now accessible via the VPN, and not via the default Internet route. What I want is a way to automatically update the routes on all of the servers, when the route is added to a routers. Now, I could install Quagga or something similar on all the servers to receive router advertisements, but that seems like overkill. So my question is what is the easiest/simpliest way to update the routing tables on the server automatically, and what protocol is best suited for this purpose. thanks

• avoid dupllcate copies in thunderbird when using gmail labels

  - by mandy

  I like the system of multiple gmail labels but am concerned about space used. I think that TB stores a separate copy of the whole email in every folder corresponding to a gmail label [including a copy in the "allmail" folder along with a separate copy in the each of the other folders]. Can I arrange to store a single copy of the email in TB,[perhaps in the allmail folder] with a shortcut type pointer from the individual folders to that single copy.[i.e for every email with one gmail label [eg personal] there are already 2 copies in TB, one in the allmail folder and a second in the "personal" folder

• IDC's Sally Hudson on Securing Mobile Access

  - by Naresh Persaud

  After the launch of Identity Management 11g R2, Oracle Magazine writer David Baum sat down with Sally Hudson, research director of security products at International Data Corporation (IDC) to get her perspective on securing mobile access.  Below is an excerpt from the interview. The complete article can be found here. "We’re seeing a much more diverse landscape of devices, computing habits, and access methods from outside of the corporate network. This trend necessitates a total security picture with different layers and end-point controls. It used to be just about keeping people out. Now, you have to let people in. Most organizations are looking toward multifaceted authentication—beyond the password—by using biometrics, soft tokens, and so forth to do this securely. Corporate IT strategies have evolved beyond just identity and access management to encompass a layered security approach that extends from the end point to the data center. It involves multiple technologies and touch points and coordination, with different layers of security from the internals of the database to the edge of the network." ( Sally Hudson, Oracle Mag Sept/Oct 2012) As the landscape changes you can find out how to adapt by reading Oracle's strategy paper on providing identity services at Internet scale.

• Collision detection code style

  - by Marian Ivanov

  Not only there are two useful broad-phase algorithms and a lot of useful narrowphase algorithms, there are also multiple code styles. Arrays vs. calling Make an array of broadphase checks, then filter them with narrowphase checks, then resolve them. function resolveCollisions(thingyStructure * a,thingyStructure * b,int index){ possibleCollisions = getPossibleCollisions(b,a->get(index)); for(i=0; i<possibleCollitionsNumber; i++){ if(narrowphase(possibleCollisions[i],a[index])) { collisions->push(possibleCollisions[i]); }; }; for(i=0; i<collitionsNumber; i++){ //CODE FOR RESOLUTION }; }; Make the broadphase call the narrowphase, and the narrowphase call the resolution function resolveCollisions(thingyStructure * a,thingyStructure * b,int index){ broadphase(b,a->get(index)); }; function broadphase(thingy * with, thingy * what){ while(blah){ //blahcode narrowphase(what,collidingThing); }; }; Events vs. in-the-loop Fire an event. This abstracts the check away, but it's trickier to make an equal interaction. a[index] -> collisionEvent(eventdata); //much later int collisionEvent(eventdata){ //resolution gets here } Resolve the collision inside the loop. This glues narrowphase and resolution into one layer. if(narrowphase(possibleCollisions[i],a[index])) { //CODE GOES HERE }; The questions are: Which of the first two is better, and how am I supposed to make a zero-sum Newtonian interaction under B1.

• Does shutdown idle VMs improve the performance?

  - by Samselvaprabu

  Often our team members are coming to me with a compliant that their VMs are slow. Our team members suggested to shutdown some of the VMs temporarily and try to access the VM. But most cases that would not help. Assume that i have assigned 4 GB for and 2 CPUs for my VM. So ideally it should not face performance issue. As our ESXi 4.1 server has multiple VM in the same server (we have overcommited memory and CPU). Does shut down other VM really helps to improve performance or not? [Note : We are using ESXi 4.1 and our hardware is R710 server. We have more number of VMs in single server so we have overcommited memory.]

• How can I solve Windows PPTP VPN issues?

  - by Robin M

  I'm having persistent problems with Windows PPTP VPN connections. The VPN appears up whilst the tunnel won't transfer traffic (ping to a remote IP within the VPN works for a while, and then fails). The client receives routing information via DHCP. When the connection fails, the routing table is still correct so I don't think it's a routing problem. My internet connection is via an ADSL2 line. There's software to deal with PPTP problems, like TunnelRat, but I don't want to install v1.1 of the .NET framework and I'd rather get to the bottom of the problem (I have multiple VPN connections and some are more unreliable than others). What can I do to get to the bottom of this? Alternatively, what can I do to keep the connection alive?

• Suddely internet is not accessible

  - by user189708

  I am going crazy here. One day everything was working fine. I turned pc off and went to sleep. Next day turn pc on and cannot access internet (from any browser). The situation is: I cannot open any webpage from browser (tried Firefox and Epiphany) and cannot receive emails in thunderbird. BUT if I run firefox from console as sudo, I can use it as usual. I can access Skype and pretty much any other network stuff (like installing software with apt-get etc.), also if I use Astrill VPN software I can access webpages even running without sudo. I haven't install any software or anything like that for several days = I have not a clue what could cause this. Just by the way, other Win PC in our home has no issue. Here is what I have tried to fix this: I have tried to restart my pc, router, modem - multiple times I have tried to change permissions to my firefox profile I have tried to completely re-install firefox and start with blank profile, thus no addons I have tried to change /etc/resolv.conf to an IP of my router (it was 127.0.1.1) I have tried to change my hostname (from tomino-NB to tominoNB) I think I might try even more stuff. None of it works. Can someone please try to help me. Thank you UPDATE 1: I have tried this: Removing resolv.conf - Didn't help Also "ping" and "dig" commands cannot resolve host UPDATE 2: I have tried to edit nameservers in resolv.conf but still no effect. I can ping router as well as I can ping outside IP. So definitely just some DNS issue. Is it possible that something is rewriting path to resolv.conf and using different file? UPDATE 3: I have just restarted PC and everything works now... resolv.conf went back to nameserver 127.0.1.1 . I have no clue what happened that it works again...

• configuring USB modem( Huawei EC156) in ubuntu 13.10

  - by user205427

  I am facing difficulty in installing my USB modem in Ubuntu 13.10. Contrary to what many have suggested,it does not get detected automatically, nor does setting a new connection help. USB Device is listed in lsusb, but not under network manager or Devices, it is detected as a CD-ROM, what I understood from the web was that usb-modeswitch can be used to switch it to a USB device. Even 'Enable Mobile Broadband' option is not shown in network manager. What was interesting is when I start laptop with windows 7 and use the USB modem and after that restart with Ubuntu, both Enable Broadband and the mobile broadband connection can be seen. Sadly, internet connection could not be installed. I tried using USB-modeswitch command as suggested somewhere, but it does not seem to work. Following is the message.

• Pattern for a class that does only one thing

  - by Heinzi

  Let's say I have a procedure that does stuff: void doStuff(initalParams) { ... } Now I discover that "doing stuff" is quite a compex operation. The procedure becomes large, I split it up into multiple smaller procedures and soon I realize that having some kind of state would be useful while doing stuff, so that I need to pass less parameters between the small procedures. So, I factor it out into its own class: class StuffDoer { private someInternalState; public Start(initalParams) { ... } // some private helper procedures here ... } And then I call it like this: new StuffDoer().Start(initialParams); or like this: new StuffDoer(initialParams).Start(); And this is what feels wrong. When using the .NET or Java API, I always never call new SomeApiClass().Start(...);, which makes me suspect that I'm doing it wrong. Sure, I could make StuffDoer's constructor private and add a static helper method: public static DoStuff(initalParams) { new StuffDoer().Start(initialParams); } But then I'd have a class whose external interface consists of only one static method, which also feels weird. Hence my question: Is there a well-established pattern for this type of classes that have only one entry point and have no "externally recognizable" state, i.e., instance state is only required during execution of that one entry point?

• How to handle user accounts for many sites running on same server

  - by Simon Courtenage

  Background to this question: I want to host multiple e-commerce sites on the same server, each with their own separate customer login application. Each site's login application needs to be secured by SSL. I'm unsure how best to handle this. For example, do I need to acquire a separate SSL certificate for each site (in which case, how do I do this dynamically, as the sites are created), or do I handle this using ONE login gateway-style application, which handles it on behalf of all the sites via a kind of transparent redirect? I'd be grateful for any pointers or advice. Thanks.

• What is the precise definition of programming paradigm?

  - by Kazark

  Wikipedia defines programming paradigm thus: a fundamental style of computer programming which is echoed in the descriptive text of the paradigms tag on this site. I find this a disappointing definition. Anyone who knows the words programming and paradigm could do about that well without knowing anything else about it. There are many styles of computer programming at many level of abstraction; within any given programming paradigm, multiple styles are possible. For example, Bob Martin says in Clean Code (13), Consider this book a description of the Object Mentor School of Clean Code. The techniques and teachings within are the way that we practice our art. We are willing to claim that if you follow these teachings, you will enjoy the benefits that we have enjoyed, and you will learn to write code that is clean and professional. But don't make the mistake of thinking that we are somehow "right" in any absolute sense. Thus Bob Martin is not claiming to have the correct style of Object-Oriented programming, even though he, if anyone, might have some claim to doing so. But even within his school of programming, we might have different styles of formatting the code (K&R, etc). There are many styles of programming at many levels. So how can we define programming paradigm rigorously, to distinguish it from other categories of programming styles? Fundamental is somewhat helpful, but not specific. How can we define the phrase in a way that will communicate more than the separate meanings of each of the two words—in other words, how can we define it in a way that will provide additional meaning for someone who speaks English but isn't familiar with a variety of paradigms?

• Ubuntu 12.04 Server ping gateway responds with destination host unreachable

  - by blckblttkd

  I consider myself fairly avid with Ubuntu and Linux, but this one has me stumped. I built up a Xen Server using Ubuntu 12.04 as the base operating system. It has multiple domUs running on it. My home network has a statically defined network where I got all the network connectivity going peachy. The server was moved to a permanent home this morning. So, the network configuration on the main system had to change. Again, another static network, but now I can't ping the upstream gateway from the host. As the VMs use this NIC over a bridge, they too are broken. Ping responds with "destination host unreachable." I simplified the networking down to a simple static network as seen below (no bridge or anything) just to get it to work. Here's the contents of my /etc/network/interfaces file: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 216.7.188.228 gateway 216.7.188.225 netmask 255.255.255.240 broadcast 216.7.188.255 network 216.7.188.0 dns-nameservers 8.8.8.8 8.8.4.4 Here's the contents of route -n 0.0.0.0 216.7.188.225 0.0.0.0 UG 100 0 0 eth0 216.7.188.224 0.0.0.0 255.255.255.240 U 0 0 0 eth0 And the results of pinging the gateway: PING 216.7.188.225 (216.7.188.225) 56(84) bytes of data. From 216.7.188.228 icmp_seq=1 Destination Host Unreachable From 216.7.188.228 icmp_seq=1 Destination Host Unreachable From 216.7.188.228 icmp_seq=1 Destination Host Unreachable Again, this worked in one network flawlessly (obviously with different parameters in the interfaces file). I did try using eth1 (as there are two NICS on the server (in case the MAC address got flipped on bootup). No success there. Yes, the cable is in the right port now :) Any thoughts? I appreciate the help!

• How to analyze data

  - by Subhash Dike

  We are working on an application that allows user to search/read some content in a particular domain. We wanted to add some capability in the app which can suggest user some content based on the usage pattern (analyze data based on frequency and relevance). Currently every time user search or read something we do store that information in backend database. We would like to use this data to present some additional content to user. Could someone explain what kind of tools will be required for such a job and any example? And what this concept is called, data analysis? data mining? business intelligence? or something else? Update: Sorry for being too broad, here is an example SQL Database (Just to give an idea, actual db is little different with normalization and stuff) Table: UserArticles Fields: UserName | ArticleId | ArticleTitle | DateVisited | ArticleCategory Table: CategoryArticles Fields: Category | Article Title | Author etc. One Category may have one more articles. One user may have read the same article multiple times (in this case we place additional entry in the user article table. Task: Use the information availabel in UserArticle table and rank categories in order which would be presented to user automatically in other part of application. Factors to be considered are frequency and recency. This might be possible through simple queries or may require specialized tools. Either way, the task is what mention above. I am not too sure which route to take, hence the question. Thoughts??

• Efficiency concerning thread granularity

  - by MaelmDev

  Lately, I've been thinking of ways to use multithreading to improve the speed of different parts of a game engine. What confuses me is the appropriate granularity of threads, especially when dealing with single-instruction-multiple-data (SIMD) tasks. Let's use line-of-sight detection as an example. Each AI actor must be able to detect objects of interest around them and mark them. There are three basic ways to go about this with multithreading: Don't use threading at all. Create a thread for each actor. Create a thread for each actor-object combination. Option 1 is obviously going to be the least efficient method. However, choosing between the next two options is more difficult. Only using one thread per actor is still running through every object in series instead of in parallel. However, are CPU's able to create and join threads in the granularity posed in Option 3 efficiently? It seems like that many calls to the OS could be really slow, and varying enormously between different hardware.

• Why does my DNS change (and break) at regular intervals?

  - by Peter Kelly

  I have a laptop running Windows 7. Up until recently, everything was fine. We have multiple devices in my house connecting to the one access point with no problems. No issues with ISP. Now my Windows 7 PC DNS settings change every minute or so. Before the problem occurs if I do an ipconfig /all I have two DNS settings (primary/secondary) and everything is fine. After a short period of time this change to a sole DNS, 10.0.0.1. Webpages no longer resolve. If I do an ipconfig /renew, this fixes the problem. I have tried uninstalling various programs I thought might be related but the problem persists. Any ideas of potential causes?

• Searchable tags in Excel?

  - by Dustin Sanders

  I'm building a database of spiders, organizing them by name, country, and region within that country. The problem is that many of the spiders exist in multiple countries and regions within that country. I want to be able to sort spiders by either country, or region, without having to enter a duplicate entry for every country or region that spider exists in. For example: Say Spider A exists in the USA and Australia. In the USA it lives in the South and North West. In Australia it lives in New South Wales. Is there a way I can make one entry for this spider, but tag it so it will show up when I search for spiders in USASouth or AustraliaNew South Wales?

• Photoshop causing other programs not receive ESC key

  When I run Photoshop CS4 on Windows 7, other running programs don't receive the ESC key (I noticed in PuTTY and Total Commander's Lister). When I close Photoshop, they start receiving the ESC key again. I tried multiple keyboard layouts, no change. Photoshop is an out-of-box install, no settings changed I exported the list of keybindings from Photoshop (ctrl-alt-shift-k) and ESC isn't used in any combination Why is this? Is there any way to disable or bypass this so that I could use other programs normally?

• What is a good way to share internal helpers?

  - by toplel32

  All my projects share the same base library that I have build up over quite some time. It contains utilities and static helper classes to assist them where .NET doesn't exactly offer what I want. Originally all the helpers were written mainly to serve an internal purpose and it has to stay that way, but sometimes they prove very useful to other assemblies. Now making them public in a reliable way is more complicated than most would think, for example all methods that assume nullable types must now contain argument checking while not charging internal utilities with the price of doing so. The price might be negligible, but it is far from right. While refactoring, I have revised this case multiple times and I've come up with the following solutions so far: Have an internal and public class for each helper The internal class contains the actual code while the public class serves as an access point which does argument checking. Cons: The internal class requires a prefix to avoid ambiguity (the best presentation should be reserved for public types) It isn't possible to discriminate methods that don't need argument checking   Have one class that contains both internal and public members (as conventionally implemented in .NET framework). At first, this might sound like the best possible solution, but it has the same first unpleasant con as solution 1. Cons: Internal methods require a prefix to avoid ambiguity   Have an internal class which is implemented by the public class that overrides any members that require argument checking. Cons: Is non-static, atleast one instantiation is required. This doesn't really fit into the helper class idea, since it generally consists of independent fragments of code, it should not require instantiation. Non-static methods are also slower by a negligible degree, which doesn't really justify this option either. There is one general and unavoidable consequence, alot of maintenance is necessary because every internal member will require a public counterpart. A note on solution 1: The first consequence can be avoided by putting both classes in different namespaces, for example you can have the real helper in the root namespace and the public helper in a namespace called "Helpers".

• merging video and audio with custom panning

  I have: a video which has mono audio inside a audio (mono) I'd like to merge those two to a single video file containing: video from #1 audio from #1 full left pan + audio #2 full right pan Is this possible in ffmpeg using 1 command? I've tried the following which almost does this but the video/audio gets out of sync: ffmpeg -i video.mp4 -filter_complex "amovie=audio.wav [r] ; [r] amerge" output.mp4 -y I've managed to do it with multiple commands: #1 create right panned audio ffmpeg -i audio.wav -ac 2 -vbr 5 audio-stereo.mp3 -y ffmpeg -i audio-stereo.mp3 -af pan=stereo:c1=c1 audio-right.mp3 -y #2 create left panned video ffmpeg -i video.mp4 -af pan=stereo:c0=c0 video-left.mp4 -y #3 merge the two ffmpeg -i video-left.mp4 -i audio-right.mp3 -filter_complex "amix=inputs=2" video-mixed.mp4 -y It does the job, but is it possible with 1 command?
