Using onboard and pci-e graphics card at the same time

- by Endle

Hello wonderful people. I know there are several other posts with similar questions. I also know how to use Google. I also have read up on posts discussing bumblebee, crossfire, ati catylist and many other interesting topics. I would just like someone to give me advice on how to use the onboard and pci-e graphics at the same time. I know the computer is capable of doing this. It works in Windows. I can use the VGA and DVI onboard port and the HDMI port of the add on card all at the same time. Works great in Windows 7, In Ubuntu, it seems only one or the other will work. I can use any combination of two displays on either adapter: VGA and HDMI..HDMI and DVI..so forth and so on. I have started experimenting with xorg.conf files, but have not been able to get any of them to work. Here is my last attempt at writing an xorg.conf file: Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" LeftOf "Screen1" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Device" Identifier "Onboard Video" Driver "radeon" BusID "PCI:01:05.0" EndSection Section "Device" Identifier "Graphics Card" Driver "radeon" BusID "PCI:02:00.0" EndSection Section "Monitor" Identifier "CRT2" Option "VendorName" "ViewSonic" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "DVI1" VendorName "ACR" ModelName "P224W" Option "DPMS" EndSection Section "Monitor" Identifier "DVI2" Option "VendorName" "Acer" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "Screen0" Device "Onboard Video" Monitor "CRT2" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Graphics Card" Monitor "DVI1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1920x1080" EndSubSection

Simple C: How do I scan this information in properly?

- by Doc

OK this is a simple question but for some reason I just can't get it right. I have to scan from a file hundreds of lines of code and store it in a array (which I can normally do a ok job with) however At one point the code will specify a number that then corresponds to the next batch of chars ints and floats going into various arrays. As I know I am not describing this correctly here is a example. one line of the file I am reading will contain something close to this. 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom the problem I am having is This part here 0221 T 2 S P 850 150 0.90 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Name_of_place 0104 L 1 F 400 1.00 0.75 500 24 2 2012 G A 7 9600.00 0.1 1000 Ballroom The rest after this is Generally the exact same however at this point the number at the front descides all the values that are going in. I am almost completely lost on how to write a way that can scan this and store the data into arrays correctly

Ubuntu 13.10. After login, no desktop displayed. Two Nvidia Graphics Cards, Four Monitors

- by jmerkow

I am working on an issue with my Ubuntu 13.10 installation. I am attempting to get 4 monitors up and running but I am having some trouble. So far, I installed and updated to the latest NVIDIA drivers (331.20). Initially X would not start (after installation) so I replaced my xorg.conf with xorg.conf.failsafe. This fixed that problem, but then I tried to enable the other 2 monitors (other video card) and xorg fails to start once again (after I login there is no desktop). I am fairly new to linux but I am not a complete beginner, but I'm not comfortable poking around too much on my own to troubleshoot yet.... lspci -nn | grep VGA: 03:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 570 Rev. 2] [10de:1086] (rev a1) 05:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF110 [GeForce GTX 580] [10de:1080] (rev a1) It seems that the nvidia-settings tool does not result in a good xorg.conf file.

Why are my Opteron cores running at only 75% capacity each? (25% CPU idle)

- by Tim Cooper

We've just taken delivery of a powerful 32-core AMD Opteron server with 128Gb. We have 2 x 6272 CPU's with 16 cores each. We are running a big long-running java task on 30 threads. We have the NUMA optimisations for Linux and java turned on. Our Java threads are mainly using objects that are private to that thread, sometimes reading memory that other threads will be reading, and very very occasionally writing or locking shared objects. We can't explain why the CPU cores are 25% idle. Below is a dump of "top": top - 23:06:38 up 1 day, 23 min, 3 users, load average: 10.84, 10.27, 9.62 Tasks: 676 total, 1 running, 675 sleeping, 0 stopped, 0 zombie Cpu(s): 64.5%us, 1.3%sy, 0.0%ni, 32.9%id, 1.3%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 132138168k total, 131652664k used, 485504k free, 92340k buffers Swap: 5701624k total, 230252k used, 5471372k free, 13444344k cached ... top - 22:37:39 up 23:54, 3 users, load average: 7.83, 8.70, 9.27 Tasks: 678 total, 1 running, 677 sleeping, 0 stopped, 0 zombie Cpu0 : 75.8%us, 2.0%sy, 0.0%ni, 22.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 77.2%us, 1.3%sy, 0.0%ni, 21.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu2 : 77.3%us, 1.0%sy, 0.0%ni, 21.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu3 : 77.8%us, 1.0%sy, 0.0%ni, 21.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu4 : 76.9%us, 2.0%sy, 0.0%ni, 21.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu5 : 76.3%us, 2.0%sy, 0.0%ni, 21.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu6 : 12.6%us, 3.0%sy, 0.0%ni, 84.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu7 : 8.6%us, 2.0%sy, 0.0%ni, 89.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu8 : 77.0%us, 2.0%sy, 0.0%ni, 21.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu9 : 77.0%us, 2.0%sy, 0.0%ni, 21.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu10 : 77.6%us, 1.7%sy, 0.0%ni, 20.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu11 : 75.7%us, 2.0%sy, 0.0%ni, 21.4%id, 1.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu12 : 76.6%us, 2.3%sy, 0.0%ni, 21.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu13 : 76.6%us, 2.3%sy, 0.0%ni, 21.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu14 : 76.2%us, 2.6%sy, 0.0%ni, 15.9%id, 5.3%wa, 0.0%hi, 0.0%si, 0.0%st Cpu15 : 76.6%us, 2.0%sy, 0.0%ni, 21.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu16 : 73.6%us, 2.6%sy, 0.0%ni, 23.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu17 : 74.5%us, 2.3%sy, 0.0%ni, 23.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu18 : 73.9%us, 2.3%sy, 0.0%ni, 23.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu19 : 72.9%us, 2.6%sy, 0.0%ni, 24.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu20 : 72.8%us, 2.6%sy, 0.0%ni, 24.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu21 : 72.7%us, 2.3%sy, 0.0%ni, 25.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu22 : 72.5%us, 2.6%sy, 0.0%ni, 24.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu23 : 73.0%us, 2.3%sy, 0.0%ni, 24.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu24 : 74.7%us, 2.7%sy, 0.0%ni, 22.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu25 : 74.5%us, 2.6%sy, 0.0%ni, 22.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu26 : 73.7%us, 2.0%sy, 0.0%ni, 24.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu27 : 74.1%us, 2.3%sy, 0.0%ni, 23.6%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu28 : 74.1%us, 2.3%sy, 0.0%ni, 23.6%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu29 : 74.0%us, 2.0%sy, 0.0%ni, 24.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu30 : 73.2%us, 2.3%sy, 0.0%ni, 24.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu31 : 73.1%us, 2.0%sy, 0.0%ni, 24.9%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 132138168k total, 131711704k used, 426464k free, 88336k buffers Swap: 5701624k total, 229572k used, 5472052k free, 13745596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13865 root 20 0 122g 112g 3.1g S 2334.3 89.6 20726:49 java 27139 jayen 20 0 15428 1728 952 S 2.6 0.0 0:04.21 top 27161 sysadmin 20 0 15428 1712 940 R 1.0 0.0 0:00.28 top 33 root 20 0 0 0 0 S 0.3 0.0 0:06.24 ksoftirqd/7 131 root 20 0 0 0 0 S 0.3 0.0 0:09.52 events/0 1858 root 20 0 0 0 0 S 0.3 0.0 1:35.14 kondemand/0 A dump of the java stack confirms that none of the threads are anywhere near the few places where locks are used, nor are they anywhere near any disk or network i/o. I had trouble finding a clear explanation of what 'top' means by "idle" versus "wait", but I get the impression that "idle" means "no more threads that need to be run" but this doesn't make sense in our case. We're using a "Executors.newFixedThreadPool(30)". There are a large number of tasks pending and each task lasts for 10 seconds or so. I suspect that the explanation requires a good understanding of NUMA. Is the "idle" state what you see when a CPU is waiting for a non-local access? If not, then what is the explanation?

No GLX on Intel card with multiseat with additional nVidia card

- by MeanEYE

I have multiseat configured and my Xorg has 2 server layouts. One is for nVidia card and other is for Intel card. They both work, but display server assigned to Intel card doesn't have hardware acceleration since DRI and GLX module being used is from nVidia driver. So my question is, can I configure layouts somehow to use right DRI and GLX with each card?

Inventory Management concepts in XNA game

- by user1332755

I am trying to code the inventory system in my first real game so I have very little experience in both c# and game engine development. Basically, I need some general guidance and tips with how to structure and organize these sorts of systems. Please tell me if I am on the right track or not before I get too deep into making some badly structured system. It's fine if you don't feel like looking through my code, suggestions about general structure would also be appreciated. What I am aiming to end up with is some sort of system like Minecraft or Terraria. It must include: main inventory GUI (items can be dragged and placed in whatever slot desired Itembar outside of the main inventory which can be assigned to certain items the ability to use items from either location So far, I have 4 main classes: Inventory holds the general info and methods, inventoryslot holds info for individual slots, Itembar holds all info and methods for itself, and finally, ItemManager to manage interactions between the two and hold a master list of items. So far, my itembar works perfectly and interacts well with mousedragging items into and out of it as well as activating the item effect. Here is the code I have so far: (there is a lot but I will try to keep it relevant) This is the code for the itembar on the main screen: class Itembar { public Texture2D itembarfull, iSelected; public static Rectangle itembar = new Rectangle(5, 218, 40, 391); public Rectangle box1 = new Rectangle(itembar.X, 218, 40, 40); //up to 10 Rectangles for each slot public int Selected = 0; private ItemManager manager; public Itembar(Texture2D texture, Texture2D texture3, ItemManager mann) { itembarfull = texture; iSelected = texture3; manager = mann; } public void Update(GameTime gametime) { } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw( itembarfull, new Vector2 (itembar.X, itembar.Y), null, Color.White, 0.0f, Vector2.Zero, 1.0f, SpriteEffects.None, 1.0f); if (Selected == 1) spriteBatch.Draw(iSelected, new Rectangle(box1.X-3, box1.Y-3, box1.Width+6, box1.Height+6), Color.White); //goes up to 10 slots } public int Box1Query() { foreach (Item item in manager.items) { if(box1.Contains(item.BoundingBox)) return manager.items.IndexOf(item); } return 999; } //10 different box queries It is working fine right now. I just put an Item in there and the box will query things like the item's effects, stack number, consumable or not etc...This one is basically almost complete. Here is the main inventory class: class Inventory { public bool isActive; public List<Rectangle> mainSlots = new List<Rectangle>(24); public List<InventorySlot> mainSlotscheck = new List<InventorySlot>(24); public static Rectangle inv = new Rectangle(841, 469, 156, 231); public Rectangle invfull = new Rectangle(inv.X, inv.Y, inv.Width, inv.Height); public Rectangle inv1 = new Rectangle(inv.X + 4, inv.Y +3, 32, 32); //goes up to inv24 resulting in a 6x4 grid of Rectangles public Inventory() { mainSlots.Add(inv1); mainSlots.Add(inv2); mainSlots.Add(inv3); mainSlots.Add(inv4); //goes up to 24 foreach (Rectangle slot in mainSlots) mainSlotscheck.Add(new InventorySlot(slot)); } //update and draw methods are empty because im not too sure what to put there public int LookforfreeSlot() { int slotnumber = 999; for (int x = 0; x < mainSlots.Count; x++) { if (mainSlotscheck[x].isFree) { slotnumber = x; break; } } return slotnumber; } } } LookforFreeSlot() method is meant to be called when I do AddtoInventory(). I'm kinda stumped about what other things I need to put in this class. Here is the inventorySlot class: (its main purpose is to check the bool "isFree" to see whether or not something already occupies the slot. But i guess it can also do other stuff like get item info.) class InventorySlot { public int X, Y; public int Width = 32, Height = 32; public Vector2 Position; public int slotnumber; public bool free = true; public int? content = null; public bool isFree { get { return free; } set { free = value; } } public InventorySlot(Rectangle slot) { slot = new Rectangle(X, Y, Width, Height); } } } Finally, here is the ItemManager (I am omitting the master list because it is too long) class ItemManager { public List<Item> items = new List<Item>(20); public List<Item> inventory1 = new List<Item>(24); public List<Item> inventory2 = new List<Item>(24); public List<Item> inventory3 = new List<Item>(24); public List<Item> inventory4 = new List<Item>(24); public Texture2D icon, filta; private Rectangle msRect; MouseState mouseState; public int ISelectedIndex; Inventory inventory; SpriteFont font; public void GenerateItems() { items.Add(new Item(new Rectangle(0, 0, 32, 32), icon, font)); items[0].name = "Grass Chip"; items[0].itemID = 0; items[0].consumable = true; items[0].stackable = true; items[0].maxStack = 99; items.Add(new Item(new Rectangle(32, 0, 32, 32), icon, font)); //master list continues. it will generate all items in the game; } public ItemManager(Inventory inv, Texture2D itemsheet, Rectangle mouseRectt, MouseState ms, Texture2D fil, SpriteFont f) { icon = itemsheet; msRect = mouseRectt; filta = fil; mouseState = ms; inventory = inv; font = f; } //once again, no update or draw public void mousedrag() { items[0].DestinationRect = new Rectangle (msRect.X, msRect.Y, 32, 32); items[0].dragging = true; } public void AddtoInventory(Item item) { int index = inventory.LookforfreeSlot(); if (index == 999) return; item.DestinationRect = inventory.mainSlots[index]; inventory.mainSlotscheck[index].content = item.itemID; inventory.mainSlotscheck[index].isFree = false; item.IsActive = true; } } } The mousedrag works pretty well. AddtoInventory doesn't work because LookforfreeSlot doesn't work. Relevant code from the main program: When I want to add something to the main inventory, I do something like this: foreach (Particle ether in ether1.ethers) { if (ether.isCollected) itemmanager.AddtoInventory(itemmanager.items[14]); } This turned out to be much longer than I had expected :( But I hope someone is interested enough to comment.

ATI propriatery drivers install latest 12.8, broke my kernel. Stuck on kernel 3.2.0-26

- by user66987

I messed up a bit. Hoping some here can help me. I tried to install the newest catalyst 12.8. Sadly, this broke my system. I was stuck in low graphics mode. I finally managed to restore the proprietary drivers, and get into ubuntu again. But now I am stuck on kernel 3.2.0.26. I had installed kernel 3.2.0-30, but the system no longer sees it. I have kernel 3.2.0-29 too, but the system cannot see that as well. In the grub menu. When I use sudo update-grub, they are both listed. Here are the output I get: Searching for GRUB installation directory ... found: /boot/grub Cannot determine root device. Assuming /dev/hda1 This error is probably caused by an invalid /etc/fstab Searching for default file ... found: /boot/grub/default Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst Searching for splash image ... none found, skipping ...

Upload File to Windows Azure Blob in Chunks through ASP.NET MVC, JavaScript and HTML5

- by Shaun

Originally posted on: http://geekswithblogs.net/shaunxu/archive/2013/07/01/upload-file-to-windows-azure-blob-in-chunks-through-asp.net.aspxMany people are using Windows Azure Blob Storage to store their data in the cloud. Blob storage provides 99.9% availability with easy-to-use API through .NET SDK and HTTP REST. For example, we can store JavaScript files, images, documents in blob storage when we are building an ASP.NET web application on a Web Role in Windows Azure. Or we can store our VHD files in blob and mount it as a hard drive in our cloud service. If you are familiar with Windows Azure, you should know that there are two kinds of blob: page blob and block blob. The page blob is optimized for random read and write, which is very useful when you need to store VHD files. The block blob is optimized for sequential/chunk read and write, which has more common usage. Since we can upload block blob in blocks through BlockBlob.PutBlock, and them commit them as a whole blob with invoking the BlockBlob.PutBlockList, it is very powerful to upload large files, as we can upload blocks in parallel, and provide pause-resume feature. There are many documents, articles and blog posts described on how to upload a block blob. Most of them are focus on the server side, which means when you had received a big file, stream or binaries, how to upload them into blob storage in blocks through .NET SDK. But the problem is, how can we upload these large files from client side, for example, a browser. This questioned to me when I was working with a Chinese customer to help them build a network disk production on top of azure. The end users upload their files from the web portal, and then the files will be stored in blob storage from the Web Role. My goal is to find the best way to transform the file from client (end user’s machine) to the server (Web Role) through browser. In this post I will demonstrate and describe what I had done, to upload large file in chunks with high speed, and save them as blocks into Windows Azure Blob Storage. Traditional Upload, Works with Limitation The simplest way to implement this requirement is to create a web page with a form that contains a file input element and a submit button. 1: @using (Html.BeginForm("About", "Index", FormMethod.Post, new { enctype = "multipart/form-data" })) 2: { 3: <input type="file" name="file" /> 4: <input type="submit" value="upload" /> 5: } And then in the backend controller, we retrieve the whole content of this file and upload it in to the blob storage through .NET SDK. We can split the file in blocks and upload them in parallel and commit. The code had been well blogged in the community. 1: [HttpPost] 2: public ActionResult About(HttpPostedFileBase file) 3: { 4: var container = _client.GetContainerReference("test"); 5: container.CreateIfNotExists(); 6: var blob = container.GetBlockBlobReference(file.FileName); 7: var blockDataList = new Dictionary<string, byte[]>(); 8: using (var stream = file.InputStream) 9: { 10: var blockSizeInKB = 1024; 11: var offset = 0; 12: var index = 0; 13: while (offset < stream.Length) 14: { 15: var readLength = Math.Min(1024 * blockSizeInKB, (int)stream.Length - offset); 16: var blockData = new byte[readLength]; 17: offset += stream.Read(blockData, 0, readLength); 18: blockDataList.Add(Convert.ToBase64String(BitConverter.GetBytes(index)), blockData); 19: 20: index++; 21: } 22: } 23: 24: Parallel.ForEach(blockDataList, (bi) => 25: { 26: blob.PutBlock(bi.Key, new MemoryStream(bi.Value), null); 27: }); 28: blob.PutBlockList(blockDataList.Select(b => b.Key).ToArray()); 29: 30: return RedirectToAction("About"); 31: } This works perfect if we selected an image, a music or a small video to upload. But if I selected a large file, let’s say a 6GB HD-movie, after upload for about few minutes the page will be shown as below and the upload will be terminated. In ASP.NET there is a limitation of request length and the maximized request length is defined in the web.config file. It’s a number which less than about 4GB. So if we want to upload a really big file, we cannot simply implement in this way. Also, in Windows Azure, a cloud service network load balancer will terminate the connection if exceed the timeout period. From my test the timeout looks like 2 - 3 minutes. Hence, when we need to upload a large file we cannot just use the basic HTML elements. Besides the limitation mentioned above, the simple HTML file upload cannot provide rich upload experience such as chunk upload, pause and pause-resume. So we need to find a better way to upload large file from the client to the server. Upload in Chunks through HTML5 and JavaScript In order to break those limitation mentioned above we will try to upload the large file in chunks. This takes some benefit to us such as - No request size limitation: Since we upload in chunks, we can define the request size for each chunks regardless how big the entire file is. - No timeout problem: The size of chunks are controlled by us, which means we should be able to make sure request for each chunk upload will not exceed the timeout period of both ASP.NET and Windows Azure load balancer. It was a big challenge to upload big file in chunks until we have HTML5. There are some new features and improvements introduced in HTML5 and we will use them to implement our solution. In HTML5, the File interface had been improved with a new method called “slice”. It can be used to read part of the file by specifying the start byte index and the end byte index. For example if the entire file was 1024 bytes, file.slice(512, 768) will read the part of this file from the 512nd byte to 768th byte, and return a new object of interface called "Blob”, which you can treat as an array of bytes. In fact, a Blob object represents a file-like object of immutable, raw data. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system. For more information about the Blob please refer here. File and Blob is very useful to implement the chunk upload. We will use File interface to represent the file the user selected from the browser and then use File.slice to read the file in chunks in the size we wanted. For example, if we wanted to upload a 10MB file with 512KB chunks, then we can read it in 512KB blobs by using File.slice in a loop. Assuming we have a web page as below. User can select a file, an input box to specify the block size in KB and a button to start upload. 1: <div> 2: <input type="file" id="upload_files" name="files[]" /><br /> 3: Block Size: <input type="number" id="block_size" value="512" name="block_size" />KB<br /> 4: <input type="button" id="upload_button_blob" name="upload" value="upload (blob)" /> 5: </div> Then we can have the JavaScript function to upload the file in chunks when user clicked the button. 1: <script type="text/javascript"> 1: 2: $(function () { 3: $("#upload_button_blob").click(function () { 4: }); 5: });</script> Firstly we need to ensure the client browser supports the interfaces we are going to use. Just try to invoke the File, Blob and FormData from the “window” object. If any of them is “undefined” the condition result will be “false” which means your browser doesn’t support these premium feature and it’s time for you to get your browser updated. FormData is another new feature we are going to use in the future. It could generate a temporary form for us. We will use this interface to create a form with chunk and associated metadata when invoked the service through ajax. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: if (window.File && window.Blob && window.FormData) { 4: alert("Your brwoser is awesome, let's rock!"); 5: } 6: else { 7: alert("Oh man plz update to a modern browser before try is cool stuff out."); 8: return; 9: } 10: }); Each browser supports these interfaces by their own implementation and currently the Blob, File and File.slice are supported by Chrome 21, FireFox 13, IE 10, Opera 12 and Safari 5.1 or higher. After that we worked on the files the user selected one by one since in HTML5, user can select multiple files in one file input box. 1: var files = $("#upload_files")[0].files; 2: for (var i = 0; i < files.length; i++) { 3: var file = files[i]; 4: var fileSize = file.size; 5: var fileName = file.name; 6: } Next, we calculated the start index and end index for each chunks based on the size the user specified from the browser. We put them into an array with the file name and the index, which will be used when we upload chunks into Windows Azure Blob Storage as blocks since we need to specify the target blob name and the block index. At the same time we will store the list of all indexes into another variant which will be used to commit blocks into blob in Azure Storage once all chunks had been uploaded successfully. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: ... ... 4: // start to upload each files in chunks 5: var files = $("#upload_files")[0].files; 6: for (var i = 0; i < files.length; i++) { 7: var file = files[i]; 8: var fileSize = file.size; 9: var fileName = file.name; 10: 11: // calculate the start and end byte index for each blocks(chunks) 12: // with the index, file name and index list for future using 13: var blockSizeInKB = $("#block_size").val(); 14: var blockSize = blockSizeInKB * 1024; 15: var blocks = []; 16: var offset = 0; 17: var index = 0; 18: var list = ""; 19: while (offset < fileSize) { 20: var start = offset; 21: var end = Math.min(offset + blockSize, fileSize); 22: 23: blocks.push({ 24: name: fileName, 25: index: index, 26: start: start, 27: end: end 28: }); 29: list += index + ","; 30: 31: offset = end; 32: index++; 33: } 34: } 35: }); Now we have all chunks’ information ready. The next step should be upload them one by one to the server side, and at the server side when received a chunk it will upload as a block into Blob Storage, and finally commit them with the index list through BlockBlobClient.PutBlockList. But since all these invokes are ajax calling, which means not synchronized call. So we need to introduce a new JavaScript library to help us coordinate the asynchronize operation, which named “async.js”. You can download this JavaScript library here, and you can find the document here. I will not explain this library too much in this post. We will put all procedures we want to execute as a function array, and pass into the proper function defined in async.js to let it help us to control the execution sequence, in series or in parallel. Hence we will define an array and put the function for chunk upload into this array. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: ... ... 4: 5: // start to upload each files in chunks 6: var files = $("#upload_files")[0].files; 7: for (var i = 0; i < files.length; i++) { 8: var file = files[i]; 9: var fileSize = file.size; 10: var fileName = file.name; 11: // calculate the start and end byte index for each blocks(chunks) 12: // with the index, file name and index list for future using 13: ... ... 14: 15: // define the function array and push all chunk upload operation into this array 16: blocks.forEach(function (block) { 17: putBlocks.push(function (callback) { 18: }); 19: }); 20: } 21: }); 22: }); As you can see, I used File.slice method to read each chunks based on the start and end byte index we calculated previously, and constructed a temporary HTML form with the file name, chunk index and chunk data through another new feature in HTML5 named FormData. Then post this form to the backend server through jQuery.ajax. This is the key part of our solution. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: ... ... 4: // start to upload each files in chunks 5: var files = $("#upload_files")[0].files; 6: for (var i = 0; i < files.length; i++) { 7: var file = files[i]; 8: var fileSize = file.size; 9: var fileName = file.name; 10: // calculate the start and end byte index for each blocks(chunks) 11: // with the index, file name and index list for future using 12: ... ... 13: // define the function array and push all chunk upload operation into this array 14: blocks.forEach(function (block) { 15: putBlocks.push(function (callback) { 16: // load blob based on the start and end index for each chunks 17: var blob = file.slice(block.start, block.end); 18: // put the file name, index and blob into a temporary from 19: var fd = new FormData(); 20: fd.append("name", block.name); 21: fd.append("index", block.index); 22: fd.append("file", blob); 23: // post the form to backend service (asp.net mvc controller action) 24: $.ajax({ 25: url: "/Home/UploadInFormData", 26: data: fd, 27: processData: false, 28: contentType: "multipart/form-data", 29: type: "POST", 30: success: function (result) { 31: if (!result.success) { 32: alert(result.error); 33: } 34: callback(null, block.index); 35: } 36: }); 37: }); 38: }); 39: } 40: }); Then we will invoke these functions one by one by using the async.js. And once all functions had been executed successfully I invoked another ajax call to the backend service to commit all these chunks (blocks) as the blob in Windows Azure Storage. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: ... ... 4: // start to upload each files in chunks 5: var files = $("#upload_files")[0].files; 6: for (var i = 0; i < files.length; i++) { 7: var file = files[i]; 8: var fileSize = file.size; 9: var fileName = file.name; 10: // calculate the start and end byte index for each blocks(chunks) 11: // with the index, file name and index list for future using 12: ... ... 13: // define the function array and push all chunk upload operation into this array 14: ... ... 15: // invoke the functions one by one 16: // then invoke the commit ajax call to put blocks into blob in azure storage 17: async.series(putBlocks, function (error, result) { 18: var data = { 19: name: fileName, 20: list: list 21: }; 22: $.post("/Home/Commit", data, function (result) { 23: if (!result.success) { 24: alert(result.error); 25: } 26: else { 27: alert("done!"); 28: } 29: }); 30: }); 31: } 32: }); That’s all in the client side. The outline of our logic would be - Calculate the start and end byte index for each chunks based on the block size. - Defined the functions of reading the chunk form file and upload the content to the backend service through ajax. - Execute the functions defined in previous step with “async.js”. - Commit the chunks by invoking the backend service in Windows Azure Storage finally. Save Chunks as Blocks into Blob Storage In above we finished the client size JavaScript code. It uploaded the file in chunks to the backend service which we are going to implement in this step. We will use ASP.NET MVC as our backend service, and it will receive the chunks, upload into Windows Azure Bob Storage in blocks, then finally commit as one blob. As in the client side we uploaded chunks by invoking the ajax call to the URL "/Home/UploadInFormData", I created a new action under the Index controller and it only accepts HTTP POST request. 1: [HttpPost] 2: public JsonResult UploadInFormData() 3: { 4: var error = string.Empty; 5: try 6: { 7: } 8: catch (Exception e) 9: { 10: error = e.ToString(); 11: } 12: 13: return new JsonResult() 14: { 15: Data = new 16: { 17: success = string.IsNullOrWhiteSpace(error), 18: error = error 19: } 20: }; 21: } Then I retrieved the file name, index and the chunk content from the Request.Form object, which was passed from our client side. And then, used the Windows Azure SDK to create a blob container (in this case we will use the container named “test”.) and create a blob reference with the blob name (same as the file name). Then uploaded the chunk as a block of this blob with the index, since in Blob Storage each block must have an index (ID) associated with so that finally we can put all blocks as one blob by specifying their block ID list. 1: [HttpPost] 2: public JsonResult UploadInFormData() 3: { 4: var error = string.Empty; 5: try 6: { 7: var name = Request.Form["name"]; 8: var index = int.Parse(Request.Form["index"]); 9: var file = Request.Files[0]; 10: var id = Convert.ToBase64String(BitConverter.GetBytes(index)); 11: 12: var container = _client.GetContainerReference("test"); 13: container.CreateIfNotExists(); 14: var blob = container.GetBlockBlobReference(name); 15: blob.PutBlock(id, file.InputStream, null); 16: } 17: catch (Exception e) 18: { 19: error = e.ToString(); 20: } 21: 22: return new JsonResult() 23: { 24: Data = new 25: { 26: success = string.IsNullOrWhiteSpace(error), 27: error = error 28: } 29: }; 30: } Next, I created another action to commit the blocks into blob once all chunks had been uploaded. Similarly, I retrieved the blob name from the Request.Form. I also retrieved the chunks ID list, which is the block ID list from the Request.Form in a string format, split them as a list, then invoked the BlockBlob.PutBlockList method. After that our blob will be shown in the container and ready to be download. 1: [HttpPost] 2: public JsonResult Commit() 3: { 4: var error = string.Empty; 5: try 6: { 7: var name = Request.Form["name"]; 8: var list = Request.Form["list"]; 9: var ids = list 10: .Split(',') 11: .Where(id => !string.IsNullOrWhiteSpace(id)) 12: .Select(id => Convert.ToBase64String(BitConverter.GetBytes(int.Parse(id)))) 13: .ToArray(); 14: 15: var container = _client.GetContainerReference("test"); 16: container.CreateIfNotExists(); 17: var blob = container.GetBlockBlobReference(name); 18: blob.PutBlockList(ids); 19: } 20: catch (Exception e) 21: { 22: error = e.ToString(); 23: } 24: 25: return new JsonResult() 26: { 27: Data = new 28: { 29: success = string.IsNullOrWhiteSpace(error), 30: error = error 31: } 32: }; 33: } Now we finished all code we need. The whole process of uploading would be like this below.

Then we can find the blob in our Windows Azure Blob Storage. Optimized by Parallel Upload In previous example we just uploaded our file in chunks. This solved the problem that ASP.NET MVC request content size limitation as well as the Windows Azure load balancer timeout. But it might introduce the performance problem since we uploaded chunks in sequence. In order to improve the upload performance we could modify our client side code a bit to make the upload operation invoked in parallel. The good news is that, “async.js” library provides the parallel execution function. If you remembered the code we invoke the service to upload chunks, it utilized “async.series” which means all functions will be executed in sequence. Now we will change this code to “async.parallel”. This will invoke all functions in parallel. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: ... ... 4: // start to upload each files in chunks 5: var files = $("#upload_files")[0].files; 6: for (var i = 0; i < files.length; i++) { 7: var file = files[i]; 8: var fileSize = file.size; 9: var fileName = file.name; 10: // calculate the start and end byte index for each blocks(chunks) 11: // with the index, file name and index list for future using 12: ... ... 13: // define the function array and push all chunk upload operation into this array 14: ... ... 15: // invoke the functions one by one 16: // then invoke the commit ajax call to put blocks into blob in azure storage 17: async.parallel(putBlocks, function (error, result) { 18: var data = { 19: name: fileName, 20: list: list 21: }; 22: $.post("/Home/Commit", data, function (result) { 23: if (!result.success) { 24: alert(result.error); 25: } 26: else { 27: alert("done!"); 28: } 29: }); 30: }); 31: } 32: }); In this way all chunks will be uploaded to the server side at the same time to maximize the bandwidth usage. This should work if the file was not very large and the chunk size was not very small. But for large file this might introduce another problem that too many ajax calls are sent to the server at the same time. So the best solution should be, upload the chunks in parallel with maximum concurrency limitation. The code below specified the concurrency limitation to 4, which means at the most only 4 ajax calls could be invoked at the same time. 1: $("#upload_button_blob").click(function () { 2: // assert the browser support html5 3: ... ... 4: // start to upload each files in chunks 5: var files = $("#upload_files")[0].files; 6: for (var i = 0; i < files.length; i++) { 7: var file = files[i]; 8: var fileSize = file.size; 9: var fileName = file.name; 10: // calculate the start and end byte index for each blocks(chunks) 11: // with the index, file name and index list for future using 12: ... ... 13: // define the function array and push all chunk upload operation into this array 14: ... ... 15: // invoke the functions one by one 16: // then invoke the commit ajax call to put blocks into blob in azure storage 17: async.parallelLimit(putBlocks, 4, function (error, result) { 18: var data = { 19: name: fileName, 20: list: list 21: }; 22: $.post("/Home/Commit", data, function (result) { 23: if (!result.success) { 24: alert(result.error); 25: } 26: else { 27: alert("done!"); 28: } 29: }); 30: }); 31: } 32: }); Summary In this post we discussed how to upload files in chunks to the backend service and then upload them into Windows Azure Blob Storage in blocks. We focused on the frontend side and leverage three new feature introduced in HTML 5 which are - File.slice: Read part of the file by specifying the start and end byte index. - Blob: File-like interface which contains the part of the file content. - FormData: Temporary form element that we can pass the chunk alone with some metadata to the backend service. Then we discussed the performance consideration of chunk uploading. Sequence upload cannot provide maximized upload speed, but the unlimited parallel upload might crash the browser and server if too many chunks. So we finally came up with the solution to upload chunks in parallel with the concurrency limitation. We also demonstrated how to utilize “async.js” JavaScript library to help us control the asynchronize call and the parallel limitation. Regarding the chunk size and the parallel limitation value there is no “best” value. You need to test vary composition and find out the best one for your particular scenario. It depends on the local bandwidth, client machine cores and the server side (Windows Azure Cloud Service Virtual Machine) cores, memory and bandwidth. Below is one of my performance test result. The client machine was Windows 8 IE 10 with 4 cores. I was using Microsoft Cooperation Network. The web site was hosted on Windows Azure China North data center (in Beijing) with one small web role (1.7GB 1 core CPU, 1.75GB memory with 100Mbps bandwidth). The test cases were - Chunk size: 512KB, 1MB, 2MB, 4MB. - Upload Mode: Sequence, parallel (unlimited), parallel with limit (4 threads, 8 threads). - Chunk Format: base64 string, binaries. - Target file: 100MB. - Each case was tested 3 times. Below is the test result chart. Some thoughts, but not guidance or best practice: - Parallel gets better performance than series. - No significant performance improvement between parallel 4 threads and 8 threads. - Transform with binaries provides better performance than base64. - In all cases, chunk size in 1MB - 2MB gets better performance.

Retrieve Performance Data from SOA Infrastructure Database

- by fip

My earlier blog posting shows how to enable, retrieve and interpret BPEL engine performance statistics to aid performance troubleshooting. The strength of BPEL engine statistics at EM is its break down per request. But there are some limitations with the BPEL performance statistics mentioned in that blog posting: The statistics were stored in memory instead of being persisted. To avoid memory overflow, the data are stored to a buffer with limited size. When the statistic entries exceed the limitation, old data will be flushed out to give ways to new statistics. Therefore it can only keep the last X number of entries of data. The statistics 5 hour ago may not be there anymore. The BPEL engine performance statistics only includes latencies. It does not provide throughputs. Fortunately, Oracle SOA Suite runs with the SOA Infrastructure database and a lot of performance data are naturally persisted there. It is at a more coarse grain than the in-memory BPEL Statistics, but it does have its own strengths as it is persisted. Here I would like offer examples of some basic SQL queries you can run against the infrastructure database of Oracle SOA Suite 11G to acquire the performance statistics for a given period of time. You can run it immediately after you modify the date range to match your actual system. 1. Asynchronous/one-way messages incoming rates The following query will show number of messages sent to one-way/async BPEL processes during a given time period, organized by process names and states select composite_name composite, state, count(*) Count from dlv_message where receive_date >= to_timestamp('2012-10-24 21:00:00','YYYY-MM-DD HH24:MI:SS') and receive_date <= to_timestamp('2012-10-24 21:59:59','YYYY-MM-DD HH24:MI:SS') group by composite_name, state order by Count; 2. Throughput of BPEL process instances The following query shows the number of synchronous and asynchronous process instances created during a given time period. It list instances of all states, including the unfinished and faulted ones. The results will include all composites cross all SOA partitions select state, count(*) Count, composite_name composite, component_name,componenttype from cube_instance where creation_date >= to_timestamp('2012-10-24 21:00:00','YYYY-MM-DD HH24:MI:SS') and creation_date <= to_timestamp('2012-10-24 21:59:59','YYYY-MM-DD HH24:MI:SS') group by composite_name, component_name, componenttype order by count(*) desc; 3. Throughput and latencies of BPEL process instances This query is augmented on the previous one, providing more comprehensive information. It gives not only throughput but also the maximum, minimum and average elapse time BPEL process instances. select composite_name Composite, component_name Process, componenttype, state, count(*) Count, trunc(Max(extract(day from (modify_date-creation_date))*24*60*60 + extract(hour from (modify_date-creation_date))*60*60 + extract(minute from (modify_date-creation_date))*60 + extract(second from (modify_date-creation_date))),4) MaxTime, trunc(Min(extract(day from (modify_date-creation_date))*24*60*60 + extract(hour from (modify_date-creation_date))*60*60 + extract(minute from (modify_date-creation_date))*60 + extract(second from (modify_date-creation_date))),4) MinTime, trunc(AVG(extract(day from (modify_date-creation_date))*24*60*60 + extract(hour from (modify_date-creation_date))*60*60 + extract(minute from (modify_date-creation_date))*60 + extract(second from (modify_date-creation_date))),4) AvgTime from cube_instance where creation_date >= to_timestamp('2012-10-24 21:00:00','YYYY-MM-DD HH24:MI:SS') and creation_date <= to_timestamp('2012-10-24 21:59:59','YYYY-MM-DD HH24:MI:SS') group by composite_name, component_name, componenttype, state order by count(*) desc; 4. Combine all together Now let's combine all of these 3 queries together, and parameterize the start and end time stamps to make the script a bit more robust. The following script will prompt for the start and end time before querying against the database: accept startTime prompt 'Enter start time (YYYY-MM-DD HH24:MI:SS)' accept endTime prompt 'Enter end time (YYYY-MM-DD HH24:MI:SS)' Prompt "==== Rejected Messages ===="; REM 2012-10-24 21:00:00 REM 2012-10-24 21:59:59 select count(*), composite_dn from rejected_message where created_time >= to_timestamp('&&StartTime','YYYY-MM-DD HH24:MI:SS') and created_time <= to_timestamp('&&EndTime','YYYY-MM-DD HH24:MI:SS') group by composite_dn; Prompt " "; Prompt "==== Throughput of one-way/asynchronous messages ===="; select state, count(*) Count, composite_name composite from dlv_message where receive_date >= to_timestamp('&StartTime','YYYY-MM-DD HH24:MI:SS') and receive_date <= to_timestamp('&EndTime','YYYY-MM-DD HH24:MI:SS') group by composite_name, state order by Count; Prompt " "; Prompt "==== Throughput and latency of BPEL process instances ====" select state, count(*) Count, trunc(Max(extract(day from (modify_date-creation_date))*24*60*60 + extract(hour from (modify_date-creation_date))*60*60 + extract(minute from (modify_date-creation_date))*60 + extract(second from (modify_date-creation_date))),4) MaxTime, trunc(Min(extract(day from (modify_date-creation_date))*24*60*60 + extract(hour from (modify_date-creation_date))*60*60 + extract(minute from (modify_date-creation_date))*60 + extract(second from (modify_date-creation_date))),4) MinTime, trunc(AVG(extract(day from (modify_date-creation_date))*24*60*60 + extract(hour from (modify_date-creation_date))*60*60 + extract(minute from (modify_date-creation_date))*60 + extract(second from (modify_date-creation_date))),4) AvgTime, composite_name Composite, component_name Process, componenttype from cube_instance where creation_date >= to_timestamp('&StartTime','YYYY-MM-DD HH24:MI:SS') and creation_date <= to_timestamp('&EndTime','YYYY-MM-DD HH24:MI:SS') group by composite_name, component_name, componenttype, state order by count(*) desc;

What is the significance of '*' (star, asterisk) in the file listing results?

- by vfclists

I have noticed that some of my files have an asterisk at end. Does the asterisk at the end have any particular significance? I think they are mostly executable and displayed in green by the ls command. You will see that ./bkmp* and ./bkmp0* have an asterisk at the end. They are executable bash scripts. Here's my output: drwxr-xr-x 7 username username 4096 Oct 2 18:28 ./ drwxr-xr-x 8 root root 4096 Oct 2 09:25 ../ -rw-r--r-- 1 username username 3724 Sep 22 03:06 .bashrc -rwxr--r-- 1 username username 319 Sep 22 03:42 .bkmp* -rwxr--r-- 1 username username 324 Sep 29 23:30 .bkmp0* drwx------ 2 username username 4096 Sep 17 13:52 .cache/ -rw-r--r-- 1 username username 675 Sep 17 13:37 .profile drwx------ 2 username username 4096 Sep 22 10:10 .ssh/ drwx------ 2 username username 4096 Sep 24 19:49 .ssh.local/ drwxr-xr-x 2 username username 4096 Sep 22 04:10 archives/ drwxr-xr-x 3 username username 4096 Sep 24 19:51 home/ -rw-r--r-- 1 username username 27511 Sep 24 19:51 username_backup.20120924_1908.tar.gz

Why are the colors worse on Ubuntu 12.04 than on Windows 7 on my Sony Vaio E-Series?

- by Simon Hoare

The colours look "lacking" and ever slightly blueish and rather washed-out and lacking in dimension. Graphics are ok - this page for example looks fine - but if I view something like a news site with high quality photos, the experience is not optimal and is noticeably inferior to Windows 7. Oddly, when I install Ubuntu as a VM on VirtualBox in Windows, the colours look as I expect them to. It's only on my dual-boot version of Ubuntu that they look wrong (not Wubi, although a previous Wubi-based installation had the same problem). Now, I have the proprietary ATI driver and I can use amdcccle to get the colours closer to what they should be, but I can't seem to do anything about colour depth. The depth settings in Xorg are all 24. I tried changing all three mentions of 24 to 32 but was forced into safety mode. Fortunately, I remembered where I'd been tinkering and got the file set back to 24.

How do I rotate my monitor using xorg?

I have just installed KUbuntu 12.10, and I am attempting to rotate my monitor 90 deg to the left. When I add the option to rotate, the monitor seems to ignore the directive.

OpenStack: How to make Cloudify use the floating IP instead of the fixed one?

- by polslinux

I have a problem with Cloudify (both 2.5 and 2.6-rc release). I have an All-In-One Openstack 2013.1.1 setup and I'm trying to use Cloudify to bootstrap a cirros 0.3.1 vm. My quantum configuration is: pool of fixed ip (10.0.0.0/24) for vm management; pool of floating ip (192.168.1.170-190) taken from 192.168.1.1/24 (my lan) When I deploy a vm first, an ip from 10.0.0.0/24 is given (I cannot reach it from my PCs because it is only for vm management) and then I associate a floating ip with which I can ping (and ssh) the deployed machine. The problem is when I do: bootstrap-cloud openstack because Cloudify stay forever into "attempting to access management vm 10.0.0.3" and this is due to the fact that 10.0.0.3 is not reachable. What can I do to get Cloudify take the floating ip instead of the fixed one?

Screen Casting using ffmpeg (too fast)

- by rowman

I can use ffmpeg to make screen casts: ffmpeg -f x11grab -s 1280x800 -i :0.0 -c:v libx264 -framerate 30 -r 30 -crf 18 out.mkv However the output comes out to be too fast paced. It also happens with GTK RecordMyDesktop if I enable the encode on the fly. So, the questions is how to get a normal video pace. Also in order to capture the sound with ffmpeg what option should be used? FFmpeg Output: ffmpeg -f x11grab -s 1280x800 -r 30 -i :0.0 -c:v libx264 -framerate 30 -r 30 -crf 18 out.mkv ffmpeg version N-35162-g87244c8 Copyright (c) 2000-2012 the FFmpeg developers built on Oct 7 2012 15:56:19 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) configuration: --enable-gpl --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libvpx --enable-x11grab --enable-libx264 --enable-nonfree --enable-version3 libavutil 51. 73.102 / 51. 73.102 libavcodec 54. 64.100 / 54. 64.100 libavformat 54. 29.105 / 54. 29.105 libavdevice 54. 3.100 / 54. 3.100 libavfilter 3. 19.102 / 3. 19.102 libswscale 2. 1.101 / 2. 1.101 libswresample 0. 16.100 / 0. 16.100 libpostproc 52. 1.100 / 52. 1.100 [x11grab @ 0xab896a0] device: :0.0 -> display: :0.0 x: 0 y: 0 width: 1280 height: 800 [x11grab @ 0xab896a0] shared memory extension found [x11grab @ 0xab896a0] Estimating duration from bitrate, this may be inaccurate Input #0, x11grab, from ':0.0': Duration: N/A, start: 1350136942.608988, bitrate: 983040 kb/s Stream #0:0: Video: rawvideo (BGR[0] / 0x524742), bgr0, 1280x800, 983040 kb/s, 30 tbr, 1000k tbn, 30 tbc [libx264 @ 0xab87320] using cpu capabilities: MMX2 SSE2Fast SSSE3 Cache64 SlowCTZ SlowAtom [libx264 @ 0xab87320] profile High 4:4:4 Predictive, level 3.2, 4:4:4 8-bit [libx264 @ 0xab87320] 264 -

laptop suspend broken after latest kernel update

- by Iestyn ap Mwg

I ran a software update (Ubuntu 14.04) on my laptop over the weekend, which included an update from kernel 3.13.0-24 to 3.13.0-27, among other things. Today i had to take my laptop to work, so closed the lid and put it in my bag. However, it never went into suspend mode! I tried several times, even rebooting. Finally I tried the previous kernel from the grub menu (reverting back to the -24 one) and suspend works the same as it always had before. Did something suspend related change between the -24 and -27 kernels used in Ubuntu 14.04? I think by only reverting to a previous kernel to temporarily fix it, i've ruled out any other software changes made during the weekend's upgrade.

Why does this exported cube have too many vertices?

- by Joewsh

I'm trying to export md5mesh models. Just as a test I decided to export a simple cube (i.e. with 8 vertices). When I opened the .md5mesh file it lists the following: numverts 24 numtris 12 numweights 24 Obviously the number of triangles makes sense: 6 faces * 2 to triangulate = 12. The model only has one bone so again it even makes sense that there is one weight for each vertex. The question is though, why is the file listing 24 vertices? Is the problem the exporter or is this normal for md5mesh's? Is it something that you have to rectify when you come to parsing the file in engine? I don't want to be parsing or drawing duplicated vertices without reason. I'm guessing it's something to do with shading and normals. Is it a case of listing each vert 3 times, one for each facing normal?

X server with nvidia driver crashing: 12.04

My X server consistently crashes. It seems like this is happening when the X server is idle. This behaviour is new with 12.04. This is only happening on the second display of a multiseat system.

ftp connection problem, vsftp server, active mode

- by Mark Szente

I have a server that runs vsftpd to handle ftp connections. One of my users have a notebook with Total Commander and WinSCP installed. Both ftp clients fail right after the connection is established to the server and it tries to download the directory listing without any particular error message. The weird thing is: the notebook works perfectly ok with other ftp servers. My ftp server also works well with other clients. In fact, this user also has a pc running on the same LAN as the notebook and the pc works well with the ftp server. We use active ftp connection mode. Passive mode works well but is not an option at this point. I would post more technical details but I don't even know what this problem is related to. Anyway, below is the server side tcpdump for the failed connection attempt. There's no further communication between the client and the server after the last line of log. Thank you very much for any hint! 23:39:24.514852 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: S 1314489715:1314489715(0) win 65535 <mss 1460,nop,wscale 3,nop,nop,sackOK> 23:39:24.514896 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: S 2633658883:2633658883(0) ack 1314489716 win 5840 <mss 1460,nop,nop,sackOK,nop,wscale 2> 23:39:24.520842 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 1 win 62500 23:39:24.523803 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 1:21(20) ack 1 win 1460 23:39:24.546858 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 1:15(14) ack 21 win 62497 23:39:24.546902 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 15 win 1460 23:39:24.547247 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 21:55(34) ack 15 win 1460 23:39:24.762806 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 55 win 62493 23:39:30.415011 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 15:28(13) ack 55 win 62493 23:39:30.454116 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 28 win 1460 23:39:31.036283 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 55:78(23) ack 28 win 1460 23:39:31.053018 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 28:34(6) ack 78 win 62490 23:39:31.053042 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 34 win 1460 23:39:31.053268 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 78:97(19) ack 34 win 1460 23:39:31.068969 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 34:40(6) ack 97 win 62488 23:39:31.069148 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 97:112(15) ack 40 win 1460 23:39:31.069179 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 112:119(7) ack 40 win 1460 23:39:31.076981 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 119 win 62485 23:39:31.077010 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 119:177(58) ack 40 win 1460 23:39:31.114979 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 40:45(5) ack 177 win 62478 23:39:31.115164 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 177:186(9) ack 45 win 1460 23:39:31.180966 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 45:53(8) ack 186 win 62476 23:39:31.181066 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 186:216(30) ack 53 win 1460 23:39:31.213065 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 53:80(27) ack 216 win 62473 23:39:31.213180 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 216:267(51) ack 80 win 1460 23:39:31.251086 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: P 80:86(6) ack 267 win 62466 23:39:31.251498 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054371220 0,nop,wscale 2> 23:39:31.290979 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: . ack 86 win 1460 23:39:34.251489 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054374220 0,nop,wscale 2> 23:39:40.249625 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054380220 0,nop,wscale 2> 23:39:43.695108 IP 195.70.xx.xx.21 > 62.201.xx.xx.1057: P 2280716551:2280716588(37) ack 3838413728 win 5840 23:39:52.248791 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054392220 0,nop,wscale 2> 23:40:16.245159 IP 195.70.xx.xx.20 > 62.201.xx.xx.5001: S 2640780713:2640780713(0) win 5840 <mss 1460,sackOK,timestamp 2054416221 0,nop,wscale 2> 23:40:29.853685 IP 195.70.xx.xx.21 > 62.201.xx.xx.1057: FP 37:51(14) ack 1 win 5840 23:40:31.241951 IP 195.70.xx.xx.21 > 62.201.xx.xx.2241: P 267:304(37) ack 86 win 1460 23:40:31.381708 IP 62.201.xx.xx.2241 > 195.70.xx.xx.21: . ack 304 win 62462

Multiple routers, subnets, gateways etc

- by allentown

My current setup is: Cable modem dishes out 13 static IP's (/28), a GB switch is plugged into the cable modem, and has access to those 13 static IP's, I have about 6 "servers" in use right now. The cable modem is also a firewall, DHCP server, and 3 port 10/100 switch. I am using it as a firewall, but not currently as a DHCP server. I have plugged into the cable modem, two network cables, one which goes to the WAN port of a Linksys Dual Band Wireless 10/100/1000 router/switch. Into the linksys are a few workstations, a few printers, and some laptops connecting to wifi. I set the Linksys to use take static IP, and enabled DHCP for the workstations, printers, etc in 192.168.1.1/24. The network for the Linksys is mostly self contained, backups go to a SAN, on that network, it all happens through that switch, over GB. But I also get internet access from it as well via the cable modem using one static IP. This all works, however, I can not "see" the static IP machines when I am on the Linksys. I can get to them via ssh and other protocols, and if I want to from "outside", I open holes, like 80, 25, 587, 143, 22, etc. The second wire, from the cable modem/fireall/switch just uplinks to the managed GB switch. What are the pros and cons of this? I do not like giving up the static IP to the Linksys. I basically have a mixed network of public servers, and internal workstations. I want the public servers on public IP's because I do not want to mess with port forwarding and mappings. Is it correct also, that if someone breaches the Linksys wifi, they still would have a hard time getting to the static IP range, just by nature of the network topology? Today, just for a test, I toggled on the DHCP in the firewall/cable modem at 10.1.10.1/24 range, the Linksys is n the 192.168.1.100/24 range. At that point, all the static IP machines still had in and out access, but Linksys was unreachable. The cable modem only has 10/100 ports, so I will not plug anything but the network drop into it, which is 50Mb/10Mb. Which makes me think this could be less than ideal, as transfers from the workstation network to the server network will be bottlenecked at 100Mb when I have 1000Mb available. I may not need to solve that, if isolation is better though. I do not move a lot of data, if any, from Linsys network to server network, so for it to pretend to be remote is ok. Should I approach this any different? I could enable DHCP on the cable modem/firewall, it should still send out the statics to the GB switch, but will also be a DHCP in 10.1.10.1/24 range? I can then plug the Linksys into the GB switch, which is now picking up statics and the 10.1.10.1/24 ranges, tell the Linksys to use 10.1.10.5 or so. Now, do I disable DHCP on the Linksys, and the cable modem/firewall will pass through the statics and 10.0.10.1/24 ranges as well? Or, could I open a second DHCP pool on the Linksys? I guess doing so gives me network isolation again, but it is just the reverse of what I have now. But I get out of the bottleneck, not that the Linksys could ever really touch real GB speeds anyway, but the managed switch certainly can. This is all because 13 statics are not that many. Right now, 6 "servers", the Linksys, a managed switch, a few SSL certs, and I am running out. I do not want to waste a static IP on the managed GB switch, or the Linksys, unless it provides me some type of benefit. Final question, under my current setup, if I am on a workstation, sitting at 192.168.1.109, the Linksys, with GB, and I send a file over ssh to the static IP machine, is that literally leaving the internet, and coming back in, or does it stay local? To me it seems like: Workstation (192.168.1.109) -> Linksys DHCP -> Linksys Static IP -> Cable Modem -> Server ( and it hits the 10/100 ports on the cable modem, slowing me down. But does it round trip the network, leave and come back in, limiting me to the 50/10 internet speeds? *These are all made up numbers, I do not use default router IP's as I will one day add a VPN, and do not want collisions. I need some recommendations, do I want one big network, or two isolated ones. Printers these days need an IP, everything does, I can not get autoconf/bonjour to be reliable on most printers. but I am also not sure I want the "server" side of my operation to be polluted by the workstation side of my operation. Unless there is some magic subetting I have not learned yet, here is what I am thinking: Cable modem 10/100, has 13 static IP, publicly accessible -> Enable DHCP on the cable modem -> Cable modem plugs into managed switch -> Managed switch gets 10.1.10.1 ssh, telnet, https admin management address -> Managed switch sends static IP's to to servers -> Plug Linksys into managed switch, giving it 10.1.10.2 static internally in Linksys admin -> Linksys gets assigned 10.1.10.x as its DHCP sending range -> Local printers, workstations, iPhones etc, connect to this -> ( Do I enable DHCP or disable it on the Linksys, just define a non over lapping range, or create an entirely new DHCP at 10.1.50.0/24, I think I am back isolated again with that method too? ) Thank you for any suggestions. This is the first time I have had to deal with less than a /24, and most are larger than that, but it is just a drop to a cabinet. Otherwise, it's a router, a few repeaters, and soho stuff that is simple, with one IP. I know a few may suggest going all DHCP on the servers, and I may one day, just not now, there has been too much moving of gear for me to be interested in that, and I would want something in the Catalyst series to deal with that.
