  • 'pip install carbon' looks like it works, but pip disagrees afterward

    - by fennec
    I'm trying to use pip to install the package carbon, a package related to statistics collection. When I run pip install carbon, it looks like everything works. However, pip is unconvinced that the package is actually installed. (This ultimately causes trouble because I'm using Puppet, and have a rule to install carbon using pip, and when puppet asks pip "is this package installed?" it says "no" and it reinstalls it again.) How do I figure out what's preventing pip from recognizing the success of this installation? Here is the output of the regular install: root@statsd:/opt/graphite# pip install carbon Downloading/unpacking carbon Downloading carbon-0.9.9.tar.gz Running setup.py egg_info for package carbon

  • Templated Razor Delegates – Phil Haack

    - by nmarun
    This post is largely based off of Phil Haack’s article titled Templated Razor Delegates. I strongly recommend reading this article first. Here’s a sample code for the same, so you can have a look at. I also have a custom type being rendered as a table. 1: // my custom type 2: public class Device 3: { 4: public int Id { get; set; } 5: public string Name { get; set; } 6: public DateTime MfgDate { get; set; } 7: } Now I can write an extension method just for this type. 1: public static class RazorExtensions 2: { 3: public static HelperResult List(this IList<Models.Device> devices, Func<Models.Device, HelperResult> template) 4: { 5: return new HelperResult(writer => 6: { 7: foreach (var device in devices) 8: { 9: template(device).WriteTo(writer); 10: } 11: }); 12: } 13: // ... 14: } Modified my view to make it a strongly typed one and included html to render my custom type collection in a table. 1: @using TemplatedRazorDelegates 2: @model System.Collections.Generic.IList<TemplatedRazorDelegates.Models.Device> 3:  4: @{ 5: ViewBag.Title = "Home Page"; 6: } 7:  8: <h2>@ViewBag.Message</h2> 9:  10: @{ 11: var items = new[] { "one", "two", "three" }; 12: IList<int> ints = new List<int> { 1, 2, 3 }; 13: } 14:  15: <ul> 16: @items.List(@<li>@item</li>) 17: </ul> 18: <ul> 19: @ints.List(@<li>@item</li>) 20: </ul> 21:  22: <table> 23: <tr><th>Id</th><th>Name</th><th>Mfg Date</th></tr> 24: @Model.List(@<tr><td>@item.Id</td><td>@item.Name</td><td>@item.MfgDate.ToShortDateString()</td></tr>) 25: </table> We get intellisense as well! Just added some items in the action method of the controller: 1: public ActionResult Index() 2: { 3: ViewBag.Message = "Welcome to ASP.NET MVC!"; 4: IList<Device> devices = new List<Device> 5: { 6: new Device {Id = 1, Name = "abc", MfgDate = new DateTime(2001, 10, 19)}, 7: new Device {Id = 2, Name = "def", MfgDate = new DateTime(2011, 1, 1)}, 8: new Device {Id = 3, Name = "ghi", MfgDate = new DateTime(2003, 3, 15)}, 9: new Device {Id = 4, Name = "jkl", MfgDate = new DateTime(2007, 6, 6)} 10: }; 11: return View(devices); 12: } Running this I get the output as: Absolutely brilliant! Thanks to both Phil Haack and to David Fowler for bringing this out to us. Download the code for this from here. Verdict: RazorViewEngine.Points += 1;

  • .Net Reflector 6.5 EAP now available

    - by CliveT
    With the release of CLR 4 being so close, we’ve been working hard on getting the new C# and VB language features implemented inside Reflector. The work isn’t complete yet, but we have some of the features working. Most importantly, there are going to be changes to the Reflector object model, and we though it would be useful for people to see the changes and have an opportunity to comment on them. Before going any further, we should tell you what the EAP contains that’s different from the released version. A number of bugs have been fixed, mainly bugs that were raised via the forum. This is slightly offset by the fact that this EAP hasn’t had a whole lot of testing and there may have been new bugs introduced during the development work we’ve been doing. The C# language writer has been changed to display in and out co- and contra-variance markers on interfaces and delegates, and to display default values for optional parameters in method definitions. We also concisely display values passed by reference into COM calls. However, we do not change callsites to display calls using named parameters; this looks like hard work to get right. The forthcoming version of the C# language introduces dynamic types and dynamic calls. The new version of Reflector should display a dynamic call rather than the generated C#: dynamic target = MyTestObject(); target.Hello("Mum"); We have a few bugs in this area where we are not casting to dynamic when necessary. These have been fixed on a branch and should make their way into the next EAP. To support the dynamic features, we’ve added the types IDynamicMethodReferenceExpression, IDynamicPropertyIndexerExpression, and IDynamicPropertyReferenceExpression to the object model. These types, based on the versions without “Dynamic” in the name, reflect the fact that we don’t have full information about the method that is going to be called, but only have its name (as a string). These interfaces are going to change – in an internal version, they have been extended to include information about which parameter positions use runtime types and which use compile time types. There’s also the interface, IDynamicVariableDeclaration, that can be used to determine if a particular variable is used at dynamic call sites as a target. A couple of these language changes have also been added to the Visual Basic language writer. The new features are exposed only when the optimization level is set to .NET 4. When the level is set this high, the other standard language writers will simply display a message to say that they do not handle such an optimization level. Reflector Pro now has 4.0 as an optional compilation target and we have done some work to get the pdb generation right for these new features. The EAP version of Reflector no longer installs the add-in on startup. The first time you run the EAP, it displays the integration options dialog. You can use the checkboxes to select the versions of Visual Studio into which you want to install the EAP version. Note that you can only have one version of Reflector Pro installed in Visual Studio; if you install into a Visual Studio that has another version installed, the previous version will be removed. Please try it out and send your feedback to the EAP forum.

  • Why did MAC-Adress Cloning Fix My Router?

    - by FranticPedantic
    I have a Belkin router, and about a year ago, I suddenly lost my internet connectivity from Comcast. The internet worked fine when I plugged it right into my laptop, so I just ignored it. When I moved to another apartmnet I eventually took the dive and called tech support. The tech told me to clone my MAC address which completely fixed the issue. Now I know what a MAC address is and I've read what MAC cloning is. What has bothered me since is that I don't see how this fixed the issue. As I have understood MAC address cloning, it has the router pretend it has the same MAC address as my computer. Here is why I don't understand why this fixes my issue: I have used several different computers with this router. Cloning the MAC address fixed it for ALL of my computers. The laptop I first used with my ISP was not the one that I eventually had connected when I cloned the address. Furthermore, I didn't have any problems for quite some time after I stopped using the first computer. It wasn't like the internet suddenly stopped working when I changed which laptop I was using Now it occurred to me that maybe there was some sort of expiration? Except... Which MAC address did it clone? It was just an option in the router administration page. Did it just pick whichever computer was connected to it? If my ISP still wanted the MAC of my first computer, how did some other computer's fix it? As mentioned earlier, why did this problem seemingly stem from nowhere? Anyway, I don't have any current problems so this is more just out of general curiosity. If anybody can explain it, it would be appreciated!

  • Error installing Sony Remote Play

    - by Iszi Rory or Isznti
    I'm trying to install Remote Play software to connect my laptop to my PS3. I've found a guide with instructions which seem to be in fairly wide use (found similar walk-throughs on numerous other sites), for running the software on a non-Vaio PC. Tech-Recipies: Playstation 3 – Use Remote Play on any Windows 7 PC The setup essentially goes like this: Download Remote Play software. Download patch by NTAuthority. Install Remote Play as normal. Reboot. Extract NTAuthority patch to Remote Play program folder. Manually register patched DLLs via CLI. Run Remote Play software. Sadly, my problem is early in - Step 3. I had to use Google to find the software download, as the link from Tech-Recipies seems broken. I found the download on Sony's site here: Sony eSupport: Remote Play with PlayStation®3 After downloading and running the software, I hit "Next" at the welcome screen and "I Agree" at the EULA screen. After this, a popup informs me that Setup is checking my computer's information. Then, Setup terminates with this error: I'm running Windows 7 Ultimate x64. Is anyone familiar with this error in this software? Is there a way to work around it? Did I perhaps pick the wrong download from Sony's site?

  • How to setup Calendar permissions for group to group

    - by Sorean
    I've been scouring the internet and so far have only been able to find examples of how to grant calendar permissions from one user to another using the Add-MailboxFolderPermission command. This is great and it was okay for when they only had a handful of users. But going forward it's not realistic to have to set individual calendar permissions for all calendars for each new user. Layout of security groups already created. Each group has a few people assigned to it. Techs Managers Admin What I am trying to accomplish is set it up so that anyone that belongs to the Managers group can view the calendars of the Tech group. Admins can view and edit the Tech group. I've found an example of adding just the security group name but I get an error of: [PS] C:\Windows\system32add-MailboxFolderPermission -Identity Techs:\Calendar -User "Admin" -AccessRights Owner The user "Admin" is either not valid SMTP address, or there is no matching information. + CategoryInfo : NotSpecified: (0:Int32) [Add-MailboxFolderPermission], InvalidExternalUserIdException + FullyQualifiedErrorId : 39352699,Microsoft.Exchange.Management.StoreTasks.AddMailboxFolderPermission Am I creating groups wrong? Am I using the wrong commands? Any guidance would be greatly appreciated.

  • How to generate thumbnails for less common video containers (mkv, ogm, mp4, flv, rmvb and mov) in wi

    - by fluxtendu
    So how to generate thumbnails for these containers? I know that the install of "DivX Plus Tech Preview: MKV on Windows 7" does it for MKV. But I think that only some registry changes are really necessary and I want it for other containers. If it's possible to avoiding the install of (always bloated) codecs packs it would be nice... Maybe only installing ffdshow or essential and separated codecs. (some time ago I have try reg files for vista without success...) Update: I have installed Win7codecs & tweaked a little its settings and I got almost everything I want. (I have also re-installed the relevant part of the divx plus tech preview to get something else than an all black preview for MKV) Issues that I still want to resolve: Find a cleaner & lighter method Almost all my rmvb and mov files got an all black preview (installing real media/quick time alternative doesn't help, is it the same with the officials?) With almost all containers (avi, mkv, ogm, mpg), I have (few) random files that don't get the preview. I could play them in WMP or another player and don't have found a pattern in the codecs used. All wmv, flv and mp4 have previews but I have less files in these containers. (I clear my thumbnails cache to test them) More generally I would like to understand how windows handle the containers & codecs to generate the previews. And a software that let me choose arbitrarily the pictures previewed would be convenient too

  • Moving symlinks into a folder based on id3 tags.

    - by Reti
    I'm trying to get my music folder into something sensible. Right now, I have all my music stored in /home/foo so I have all of the albums soft linked to ~/music. I want the structure to be ~/music/<artist>/<album> I've got all of the symlinks into ~/music right now so I just need to get the symlinks into the proper structure. I'm trying to do this by delving into the symlinked album, getting the artist name with id3info. I can do this, but I can't seem to get it to work correctly. for i in $( find -L $i -name "*.mp3" -printf "%h\n") do echo "$i" #testing purposes #find its artist #the stuff after read file just cuts up id3info to get just the artist name #$artist = find -L $i -name "*.mp3" | read file; id3info $file | grep TPE | sed "s|.*: \(.*\)|\1|"|head -n1 #move it to correct artist folder #mv "$i" "$artist" done Now, it does find the correct folder, but every time there is a space in the dir name it makes it a newline. Here's a sample of what I'm trying to do $ ls DJ Exortius/ The Trance Mix 3 Wanderlust - DJ Exortius [TRANCE DEEP VOCAL TECH]@ I'm trying to mv The Trance Mix 3 Wanderlust - DJ Exortius [TRANCE DEEP VOCAL TECH]@ into the real directory DJ Exortius. DJ Exortius already exists, so it's just a matter of moving it into the correct directory that's based on the id3 tag of the mp3 inside. Thanks! PS: I've tried easytag, but when I restructure the album, it moves it from /home/foo which is not what I want.

  • Limiting bandwith on an Windows 7 machine

    - by Mihai Damian
    I need to limit the bandwidth on my Windows 7 x64 machine. In the past (on XP) I've been able to use NetLimiter for similar tasks. However for some reason I can't get it to work anymore. For lower limits the bandwidth tests are able to exceed the limit by 10-50%; higher limits seem to be ignored completely and the bandwidth tests report download speeds of over 10 times the speed I set. I'm using speedtest.net and some similar service from my ISP for these tests. Anyway, I don't necessarily need a program as complex as NetLimiter since I only need to throttle my machine's bandwidth, not a specific program's. In case you are wondering why in the world I'd want to cripple my Internet speed, there is a funny story behind this. Long story short, my modem gets random disconnects. Tech support comes in, says my Internet speed is abnormally high and I must be using some tools to somehow make it go faster than it's supposed to and this messes up my modem. I check the connection with another computer and it seems that my PC is the only one in my network that gets abnormal speeds. I reinstall my OS, speed looks normal at first, after I install the batch of 50 or so updates, it goes back to abnormally high speeds and the disconnect problems are not solved. Now I don't have a clue if the explanation the tech team gave me was just a strategy to lay the blame on someone else, but I was trying to give them the benefit of the doubt and see what happens if I really reduce my speed to their specification. Any help appreciated.

  • Dell R320 RAID 10 with CacheCade

    - by Geekman
    I'm looking for a higher-performance build for our 1RU Dell R320 servers, in terms of IOPS. Right now I'm fairly settled on: 4 x 600 GB 3.5" 15K RPM SAS RAID 1+0 array This should give good performance, but if possible, I want to also add an SSD Cache into the mix, but I'm not sure if there's enough room? According to the tech-specs, there's only up to 4 total 3.5" drive bays available. Is there any way to fit at least a single SSD drive along-side the 4x3.5" drives? I was hoping there's a special spot to put the cache SSD drive (though from memory, I doubt there'd be room). Or am I right in thinking that the cache drives are simply drives plugged in "normally" just as any other drive, but are nominated as CacheCade drives in the PERC controller? Are there any options for having the 4x600GB RAID 10 array, and the SSD cache drive, too? Based on the tech-specs (with up to 8x2.5" drives), maybe I need to use 2.5" SAS drives, leaving another 4 bays spare, plenty of room for the SSD cache drive. Has anyone achieved this using 3.5" drives, somehow?

  • Are there any tests I can run on a network to simulate 100 heavy network users?

    - by marc.gayle
    I will be hosting a Ruby on Rails workshop at a small hotel in the near future, and while they have 'Wifi' everywhere on the property, and the property normally hosts 150 - 300 people, I am not 100% confident that they have hosted 150 tech people that tend to have heavy web surfing habits/needs. Their tech department is also 1 or 2 guys. Are there any automated tests I can download and run from my laptop, on the network, that would simulate 100 'heavy users' on the network at the same time? Their broadband pipe is a 15mbps cable connection. Would that suffice for the general surfing needs of 100 - 150 techies? I know all it takes is 1 or 2 bit torrenters to kill the entire network, but assuming we can at the very least block those ports or encourage the attendees not to file share on the network, would that speed suffice for general surfing needs? What are good resources online that would allow me to quickly get up to speed on the IT related issues, so that I can ask their sysadmins the right questions? Edit: Note that I am fairly technical, so assume I can get up to speed quickly even with technical manuals, etc.

  • How do I determine how future-proof and stable a router is?

    - by Aarthi
    I mentioned in my last question that my wireless router had a bad habit of crashing. After consulting with the Super User chatroom, as well as my sysadmin, I've decided I may as well purchase a new router. However, I'm unsure how to evaluate all these tech specs that get touted about. The two things that seem to be the most important to me are: (1) keeping my router future-proof (as standards evolve and change), and (2) ensuring its stability. Unfortunately, I'm not sure what, exactly, I should be looking for in the tech specs or the item description that can give me a good idea of how stable or future-proof my decide will be. What should I look for? Can I determine stability without having to try the device out myself? Please note: I'm not a battle-hardened power user by any means, so I'll likely be reliant on the given firmware for my router. My last router lasted me like four years, so I mostly just want something that'll cover a 500 sqft apartment in New York with minimal crashing, so that I can watch Hulu in peace. And make Skype calls. If it helps, the router models that I'm currently decided between are this ASUS one and this LinkSys one.

  • Embedded Windows XP

    - by Kyle
    My company acquired a brake press for bending large structural steel plates. We received it second hand and it came with an embedded copy of windows XP. Now for the part that's driving me nuts: plug and play has been turned off, also accessibility options has been disabled. What does this mean for me? Keyboards will not work! Nothing that plugs into a USB port will work and it does not have a CD ROM drive. I have tried to turn on plug and play using the on screen keyboard but it is not there since accessibility options is turned off. I would just get an updated copy of the the embedded OS but they come from Sweden and are extremely expensive. I assume there has got to be a way to get a USB devices to work. We need to get a wifi adapter on it so I can use team viewer and remotely configure it for our needs. Things to keep in mind: There is no keyboard so everything has to be done with the mouse There is no PS2 port for a keyboard just a mouse. Odd. I am 5 states away from this location and have been working with a tech who is physically installing the machine. System 32 seems to be missing A LOT of files, the tech told me there is only 8 folders in there and no other files (I don't even understand how Windows is running like this). If anyone has ANY ideas I would appreciate it, I am unsure where to go from here.

  • How to create a WHM/cPanel account, without creating a new sub-domain?

    - by Cyclops
    I have a basic VPS (full root access), with WHM/cPanel, and am learning the ropes. I'm trying to create a new account for an existing domain (mysite.com), and so far WHM won't let me - it either wants a sub-domain or fake domain, but won't allow two accounts for one domain. In the beginning, there was only the root account, and it wouldn't let me login to cPanel - a quick chat with tech support, and I am informed that I need to create a second account, which I did. So now I have an account, call it ns1me, for domain mysite.com. Now I want to create a django account. I go through the same process, but WHM won't allow me to use mysite.com as the domain for django. The docs recommend a sub-domain, so I fill the box in with django.mysite.com. I then realize that has actually created a sub-domain - going to django.mysite.com shows me its home directory, along with helpful information about what version of Apache, Python, and other mods its running (thanks, Apache). I really don't want a sub-domain, so that's out. Another chat with tech support, and they recommend a fake domain name, as it won't create anything. Sure enough, using a domain of djangomysite.com works, and WHM allows me to create a django account. But of course, I can't send email to [email protected] (where I could to [email protected]). What I want, is to be able to create a second account, associated with mysite.com (so I can run cPanel logged in as django, send email to [email protected], etc) - without creating a whole new sub-domain, or fake domain.

  • Nvidia GTX 660m crashes games

    - by dcap
    I just recently bought a Lenovo y580 with both HD intel graphics and an Nvidia GTX 660m. It works great except for one thing: playing games. Every time I load a game, either with Steam or Games for Windows Live, games will end up crashing. I've already talked with lenovo tech support and they couldn't help other than send my new laptop for repair which would take 7 days. So before I do that I thought I'd ask around. These are the games I've tested and what happens when they load: Civilization V: Game loads fine but once it gets loaded to the game, there's noticeable "tearing" popping up and certain things flash. Within a minute of this, the game crashes. Does the same thing regardless if Vsync is on or off. Total War Shogun2: Game gets to the menu screen. The background of the menu screen shows what is expected - slideshow of in-game environments rendered on high settings (this is expected). However, within 2 seconds of the menu loading up it crashes. Age of Empires 3 (Non-steam): This game is several years old so it should work on this brand new laptop fine. However the results are similar to that of Civilization V. Noticeable "Tearing" and after a few seconds it'll freeze/crash. I've done tests on all these games with both the latest stable Nvidia driver 285 as well as the nightly build 307. In addition, Nvidia control panel is set on using the dedicated graphics card for all programs. So is there anything I can do to fix this or will I have to send it back for a week to tech support?

  • OpenCV Video capture and fps problem

    - by Andrea Girardi
    Hi to all, I'm capturing video from my webcam using OpenCV on MacOSX. It works fine but when I try to play on QuickTime my captured video it plays too fast. i.e. I capture from camera for 10 seconds but when I play on QuickTime the video is 2 seconds. I've tried to change fps from 25 to 10 and It's works quite fine, but I'm sure it's not the correct process: CvVideoWriter *writer = 0; int isColor = 1; int fps = 25; int frameW = 640; // 744 for firewire cameras int frameH = 480; // 480 for firewire cameras The problem is that for now I've to capture with WebCam but the real pourpose of program is to capture image from any external source connected to my Mac. I'm using this code to capture: for (;;) { cvGrabFrame(capture) image = cvRetrieveFrame(capture); cvWriteFrame( writer, image ); } Any hint? I'm also showing webcam output on cvNamedWindow, how can I improve quality in this windows? thanks a lot to all! Andrea!

  • Web application creation in IIS7 via MS.Web.Admin

  • Rails Associations - Callback Sequence/Magic

    - by satynos
    Taking following association declaration as an example: class Post has_many :comments end Just by declaring the has_many :comments, ActiveRecord adds several methods of which I am particularly interested in comments which returns array of comments. I browsed through the code and following seems to be the callback sequence: def has_many(association_id, options = {}, &extension) reflection = create_has_many_reflection(association_id, options, &extension) configure_dependency_for_has_many(reflection) add_association_callbacks(reflection.name, reflection.options) if options[:through] collection_accessor_methods(reflection, HasManyThroughAssociation) else collection_accessor_methods(reflection, HasManyAssociation) end end def collection_accessor_methods(reflection, association_proxy_class, writer = true) collection_reader_method(reflection, association_proxy_class) if writer define_method("#{reflection.name}=") do |new_value| # Loads proxy class instance (defined in collection_reader_method) if not already loaded association = send(reflection.name) association.replace(new_value) association end define_method("#{reflection.name.to_s.singularize}_ids=") do |new_value| ids = (new_value || []).reject { |nid| nid.blank? } send("#{reflection.name}=", reflection.class_name.constantize.find(ids)) end end end def collection_reader_method(reflection, association_proxy_class) define_method(reflection.name) do |*params| force_reload = params.first unless params.empty? association = association_instance_get(reflection.name) unless association association = association_proxy_class.new(self, reflection) association_instance_set(reflection.name, association) end association.reload if force_reload association end define_method("#{reflection.name.to_s.singularize}_ids") do if send(reflection.name).loaded? || reflection.options[:finder_sql] send(reflection.name).map(&:id) else send(reflection.name).all(:select => "#{reflection.quoted_table_name}.#{reflection.klass.primary_key}").map(&:id) end end end In this sequence of callbacks, where exactly is the actual SQL being executed for retrieving the comments when I do @post.comments ?

  • Understanding asp.net mvc IView and IView.Render

    - by Harpreet
    I'm trying to devise a method of doing VERY simple asp.net mvc plugins but mostly I'm trying to understand how view rendering works. I've distilled my problem down to this public class CustomView : IView { public void Render(ViewContext viewContext, TextWriter writer) { writer.Write( /* string to render */); } } Now, within that write method I can render any string to the view but when I put a line of code in there wrapped with <% % it renders the code to the view literally rather than parsing it and executing it. I've tried adding things like <% @Page ... to the beginning of the string and it just renders that literally as well. Among many attempts I'm currently calling it this way within a controller action: ... CustomView customView = new CustomView(); ViewResult result = new ViewResult(); result.View = customView; result.ViewName = "Index.aspx"; result.MasterName = ""; return result; What am I missing or doing wrong that this won't work? The ViewResult seems to have the WebFormViewEngine in its ViewEngines collection. I just want to understand this and after stripping it down to what I think should be the minimum it doesn't behave as I think it should. I'm guessing some other part of the machinery is involved/missing but I can't figure out what.

  • Trouble converting an MP3 file to a WAV file using Naudio

    - by WebDevHobo
    Naudio Library: http://naudio.codeplex.com/ I'm trying to convert an MP3 file to a WAV file, but I've run in to a small error. I know what's going wrong, but I don't really know how to go about fixing it. Here's the piece of code I'm running: private void button1_Click(object sender, EventArgs e) { using(Mp3FileReader reader = new Mp3FileReader(@"path\to\MP3")) { using(WaveFileWriter writer = new WaveFileWriter(@"C:\test.wav", new WaveFormat())) { int counter = 0; while(reader.Read(test, counter, test.Length + counter) != 0) { writer.WriteData(test, counter, test.Length + counter); counter += 512; } } } } reader.Read() goes into the Mp3FileReader class, and the method looks like this: public override int Read(byte[] sampleBuffer, int offset, int numBytes) { if (numBytes % waveFormat.BlockAlign != 0) //throw new ApplicationException("Must read complete blocks"); numBytes -= (numBytes % waveFormat.BlockAlign); return mp3Stream.Read(sampleBuffer, offset, numBytes); } mp3Stream is an object of the Stream class. The problem is: I'm getting an ArgumentException. MSDN says that this is because the sum of offset and numBytes is greater than the length of sampleBuffer. Documentation: http://msdn.microsoft.com/en-us/library/system.io.stream.read.aspx This happens because I increase the counter every time, but the size of the byte array test remains the same. What I've been wondering is: do I need to increase the size of the array dynamically, or do I need to find out the needed size at the beginning and set it right away? And also, instead of 512, the method in Mp3FileReader returns 365 the first time. Which is the size of a whole block. But I'm writing the full 512. I'm basically just using the read to check if I'm not at the end of the file yet. Do I need to catch the return value and do something with that, or am I good here?
