• Alternate way to create a clone of a UNIX System

  - by Spirit

  THE STORY: (If you don't like to read much, down below is the question :) ) Where I work we have two HP RP2470 servers same hardware same number of hard drives same everything :). One of them is a production server and runs HP-UX 11.00. The poor ba***rd hasn't been turned off for years and now I have to make a clone of it on the other server - just in case, for redundancy. The problem is simple (or not simple) as I have to make the the other server exactly the same. However the old version of OS (UX 11.00 is a history now) and the old software running on it, have made my task almost impossible. On the production server there is also a cloning/recover utility Ignite-UX. I tried many times to create a recovery tape with it. Then when I load the tape on the backup server, it succeeds with the loading of the tape (no errors no warnings) but on the next restart it fails to load the OS :S and drops into HP`s ISL prompt. --- THE QUESTION: Is there an alternate way to create a clone of the Unix System? The environment is: 1. 2x HP RP2470 Servers (non-Intel), same hardware, same number od HDDs (two each of them) same everything. 2. OS running: HP-UX 11.00 The production server has to be cloned without downtime - sadly :( as I hope that they will reconsider on this one For example (like on Windows platforms), if you try to copy an entire HDD with Windows inside on another HDD, and then put that HDD on another PC it will still work, as long as the hardware is the same. Can I do something like that with a Unix system? Can I somehow COPY the contents of the entire HDD, put those on another HDD, and then just load the HDD into the other server? (If you haven't read the story the servers are exactly the same) Will it work? Can it be done with ordinary commands like cp or dump or something like that? Does any one have a similar experience? --- UPDATE: 26.01.2012 NOTE: The update is related to "The Story". If you haven't read that part then you can skip this update.

• Commit in sharpSVN

  - by Pedro

  Hello! I have a problem doing commit with sharpsvn. Now i´m adding all the files of my working copy (if the file is added throws an exception), and after it i do commit. It works but it trows exceptions. There is some way to get the status of the repository before do add() and only add the new files or the files who are changed? And if i delete one file or folder on my working copy , How can i delete these files or folder on the repository? Code: String[] folders; folders = Directory.GetDirectories(direccionLocal,"*.*", SearchOption.AllDirectories); foreach (String folder in folders) { String[] files; files = Directory.GetFiles(folder); foreach (String file in files) { if (file.IndexOf("\\.svn") == -1) { Add(file, workingcopy); } } } Commit(workingcopy, "change"); Add: public bool Add(string path, string direccionlocal) { using (SvnClient client = new SvnClient()) { SvnAddArgs args = new SvnAddArgs(); args.Depth = SvnDepth.Empty; Console.Out.WriteLine(path); args.AddParents = true; try { return client.Add(path, args); } catch (Exception ex) { return false; } } } Commit: public bool Commit(string path, string message) { using (SvnClient client = new SvnClient()) { SvnCommitArgs args = new SvnCommitArgs(); args.LogMessage = message; args.ThrowOnError = true; args.ThrowOnCancel = true; try { return client.Commit(path, args); } catch (Exception e) { if (e.InnerException != null) { throw new Exception(e.InnerException.Message, e); } throw e; } } }

• VS2010 - How to automatically stop compile on first compile error

  - by Ben Robbins

  {rant}First I'd like to say that this IS NOT A DUPLICATE. I've asked this question previously but it got closed as a duplicate when it isn't. This question is SPECIFIC to VS 2010 and the answers to the so-called duplicate work in VS 2008 but not in VS 2010 (at least not for me or anyone I know). So before you go closing something as a duplicate how about you read the question carefully and try the answer for yourself and see if it actually works. Apologies for the rant but there is no obvious way to contact the SO police that closed the issue or get it reopened. {/rant} At work we have a C# solution with over 80 projects. In VS 2008 we use a macro to stop the compile as soon as a project in the solution fails to build (see this question for several options for VS 2005 & VS 2008: http://stackoverflow.com/questions/134796/how-to-automatically-stop-visual-c-build-at-first-compile-error). Is it possible to do the same in VS 2010? What we have found is that in VS 2010 the macros don't work (at least I couldn't get them to work) as it appears that the environment events don't fire in VS 2010. The default behaviour is to continue as far as possible and display a list of errors in the error window. I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). Answers for VS 2010 only please. If the macros do work then a detailed explanation of how to configure them for VS 2010 would be appreciated. Thanks.

• MSTest: Problems with DeploymentItem attribute

  - by Juri

  Hi, I'm currently maintaining an "old" system written in C#.net, removing some obsolete features and doing some refactoring. Thanks god, the previous guy wrote some unit tests (MSTests). I quite comfortable with JUnit tests, but didn't do yet much with MSTests. The test methods have a DeploymentItem attribute, specifying a text file which is parsed by the business logic method that is being tested and a 2nd DeploymentItem where just a path has been specified containing a bunch of TIF files that have to be deployed too. [TestMethod()] [DeploymentItem(@"files\valid\valid_entries.txt")] [DeploymentItem(@"files\tif\")] public void ExistsTifTest() { ... } The tests worked before, but now I had to change the names of the TIF files contained in the \files\tif directory. According to a rule, the TIF filenames have to match a certain pattern which is also checked by the ExistsTifTest() method. Now I had to change the filenames in order to adapt them to the new requirements and suddently the TIF files are no more being deployed as before. Can someone give me a hint why this happens or what may be the cause? The same thing happens also if I add a new text-file say "my2ndTest.txt" beside the "valid_entries.txt" in the \files\valid\ directory with the according DeploymentItem attribute on the test method. The file doesn't get deployed? I got the images now deployed by defining the deployment path directly in the testrunconfig, but I'd like to understand why these things happen or why for instance my new file "my2ndTest.txt" doesn't get deployed while the others do. Thanks a lot. Juri

• Environment variable names with parentheses, like %ProgramFiles(x86)%, in PowerShell?

  - by jwfearn

  How does one get the value of environment variable whose name contains parentheses in a PowerShell script? To complicate matters, some variables names contains parentheses while others have similar names without parenteses. For example (using cmd.exe): C:\>set | find "ProgramFiles" CommonProgramFiles=C:\Program Files\Common Files CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files ProgramFiles=C:\Program Files ProgramFiles(x86)=C:\Program Files (x86) We see that %ProgramFiles% is not the same as %ProgramFiles(x86)%. My PowerShell code is failing in a weird way because it's ignoring the part of the environment variable name after the parentheses. Since this happens to match the name of a different, but existing, environment variable I don't fail, I just get the right value of the wrong variable. Here's a test function in the PowerShell scripting language to illustrate my problem: function Do-Test { $ok = "C:\Program Files (x86)" # note space between 's' and '( $bad = "$Env:ProgramFiles" + "(x86)" # uses %ProgramFiles% $bin32 = "$Env:ProgramFiles(x86)" # LINE 6, I want to use %ProgramFiles(x86)% if ( $bin32 -eq $ok ) { Write-Output "Pass" } elseif ( $bin32 -eq $bad ) { Write-Output "Fail: %ProgramFiles% used instead of %ProgramFiles(x86)%" } else { Write-Output "Fail: some other reason" } } And here's the output: PS> Do-Test Fail: %ProgramFiles% used instead of %ProgramFiles(x86)% Is there a simple change I can make to line 6 above to get the correct value of %ProgramFiles(x86)%? *NOTE: In the text of this post I am using batch file syntax for environment variables as a convenient shorthand. For example %SOME_VARIABLE% means "the value of the environment variable whose name is SOME_VARIABLE". If I knew the properly escaped syntax in PowerShell, I wouldn't need to ask this question.*

• Mark duplicates in MySql with php (without deleting)

  - by Adam

  So, I'm having some problems with a MySQL query (see other question), and decided to try a different approach. I have a database table with some duplicate rows, which I actually might need for future reference, so I don't want to remove. What I'm looking for is a way to display the data without those duplicates, but without removing them. I can't use a simple select query (as described in the other question). So what I need to do is write a code that does the following: 1. Go through my db Table. 2. Spot duplicates in the "ip" column. 3. Mark the first instance of each duplicate with "0" (in a column named "duplicate") and the rest with "1". This way I can later SELECT only the rows WHERE duplicate=0. NOTE: If your solution is related to the SELECT query, please read this other question first - there's a reason I'm not just using GROUP BY / DISTINCT. Thanks in advance.

• form with multiple upload but allow no upload on edit problems

  - by minus4

  hiya i have a section that when created takes in images, however when you edit this item i dont want them to re-upload none changes images just to change a description or name. i have created this that deals with uploading files: public void UploadFiles(string currentFileName, FormCollection form) { // loop through all files in form post foreach (string file in Request.Files) { HttpPostedFileBase hpf = Request.Files[file]; // if no file is uploaded, we could be editing so set to current value if (hpf.ContentLength == 0) { form[file] = currentFileName; } else { //rename the file unique so we dont clash with names var filename = hpf.FileName.Replace(" ", "_").Replace(".", DateTime.Now.Date.Ticks + "."); UploadFileName = filename; hpf.SaveAs(Server.MapPath("~/Content/custom/" + filename)); // set the name of the file in our post to the new name form[file] = UploadFileName; } } // ensure value is still sent when no files are uploaded on edit if(Request.Files.Count <= 0) { UploadFileName = currentFileName; } } all works fine when only one image is required (CurrentFileName), however there is now a new image available taking it to a total of 2 images in the database therefor currentFileName is obsolete. has anyone tackled this and how as i have hit a wall with this one. thought of string[] currentFiles but cant see how to match this into string file in Request.Files. if it helps i am also working with models for the form so i could pass over the model but i dont think your able to do model.file without some kind of reflection. help much appreciated. thanks

• Out of Core Implementation of a Quadtree

  - by Nima

  Hi, I am trying to build a Quadtree data structure(or let's just say a tree) on the secondary memory(Hard Disk). I have a C++ program to do so and I use fopen to create the files. Also, I am using tesseral coding to store each cell in a file named with its corresponding code to store it on the disk in one directory. The problem is that after creating about 1,100 files, fopen just returns NULL and stops creating new files. I can create further files manually in that directory, but using C++ it can not create any further files. I know about max limit of inode on ext3 filesystem which is (from Wikipedia) 32,000 but mine is way less than that, also note that I can create files manually on the disk; just not through fopen. Also, I really appreciate any idea regarding the best way to store a very dynamic quadtree on disk(I need the nodes to be in separate files and the quadtree might have a depth of 50). Using nested directories is one idea, but I think it will slow down the performance because of following the links on the filesystem to access the file. Thanks, Nima

• Transaction Isolation Level of Serializable not working for me

  - by Shahriar

  I have a website which is used by all branches of a store and what it does is that it records customer purchases into a table called myTransactions.myTransactions table has a column named SerialNumber.For each purchase i create a record in the transactions table and assign a serial to it.The stored procedure that does this calls a UDF function to get a new serialNumber before inserting the record.Like below : Create Procedure mytransaction_Insert as begin insert into myTransactions(column1,column2,column3,...SerialNumber) values( Value1 ,Value2,Value3,...., getTransactionNSerialNumber()) end Create function getTransactionNSerialNumber as begin RETURN isnull(SELECT TOP (1) SerialNumber FROM myTransactions READUNCOMMITTED ORDER BY SerialNumber DESC),0) + 1 end The website is being used by so many users in different stores at the same time and it is creating many duplicate serialNumbers(same SerialNumbers).So i added a Sql transaction with ReadCommitted level to the transaction and i still got duplicate transaction numbers.I changed it to SERIALIZABLE in order to lock the resources and i not only got duplicate transaction numbers(!!HOW!!) but i also got sporadic deadlocks between the same stored procedure calls.This is what i tried : (With ommissions of try catch blocks and rollbacks) Create Procedure mytransaction_Insert as begin SET TRANSACTION ISOLATION LEVEL SERIALIZABLE BEGIN TRASNACTION ins insert into myTransactions(column1,column2,column3,...SerialNumber) values( Value1 ,Value2 , Value3, ...., getTransactionNSerialNumber()) COMMIT TRANSACTION ins SET TRANSACTION ISOLATION READCOMMITTED end I even copied the function that gets the serial number directly into the stored procedure instead of the UDF function call and still got duplicate serialNumbers.So,How can a stored procedure line create something Like the c# lock() {} block. By the way,i have to implement the transaction serial number using the same pattern and i can't change the serialNumber to any other identity field or whatever.And for some reasons i need to generate the serialNumber inside the databse and i can't move SerialNumber generation to application level. Thank you.

• Using MEF with exporting project that uses resources (xml) contained in the xap.

  - by JSmyth

  I'm doing a proof of concept app in SL4 using MEF and as part of the app I am importing another xap from an existing Silverlight Project and displaying it in my host project. The problem is that the existing app uses some .xml files (as content) and it uses linq2xml to load these files which are (assumed to be) bundled in the xap. When I compose the application the initalization fails because the host app doesn't contain the xml files. If I copy these xml files into the host project and run it the composition works fine. However, I need to keep the xml files in the original project. Is there a way that I can download a xap and look at it's contents for xml files and then load them into the host xap at runtime so that after the compostion takes place the xml resources that are required can be found? Or should I work out some kind of contract with an import/export to pass the xml files to the host xap? As the people developing the imported xaps (should the project go ahead) are from a different company, I would like to keep changes to the way they develop their apps to a minimum.

• Best practises for Magento Deployment

  - by Spongeboy

  I am looking setting up a deployment process for a highly customised Magento site, and was wondering how other people do this. I will be setting up dev, UAT and prod environments. All the Magento files will be in source control (SVN). At this stage, I can't see any requirements for changing the DB, so the 3 databases will be manually maintained. Specifically, How do you apply Magento upgrades? (Individually in each env, or on dev then roll out, or just give up on upgrades?) What files/folders do leave alone in each environment (e.g. magento/app/etc/local.xml) Do you restrict developers to editing specific files/folders? Do you restrict theme designers to editing specific files/folders? How do you manage database changes? Theme Designer Files/Folders Designers can restricted to editing the following folders- app/design/frontend/your_interface/your_theme/layout/ app/design/frontend/your_interface/your_theme/template/ app/design/frontend/your_interface/your_theme/locale/ skin/frontend/your_interface/your_theme/ Extension Developer Files/Folders Extension developers can edit the following folders/files- /app/code/local /app/etc/modules/<Namespace>_<Module>.xml Database environment management As the store's base URL is stored in the database, you cannot just copy databases between environments. Options include- Overriding the base url in php. Blog article on setting up dev and staging databases Changing the base url in the database after copying. (Where is this stored?) Doing a MySQLDump or backup, then doing a replace on the URL in the SQL file.

• Two way sync with rsync

  - by mwm

  I have a folder a/ and a remote folder A/. I now run something like this on a Makefile: get-music: rsync -avzru server:/media/10001/music/ /media/Incoming/music/ put-music: rsync -avzru /media/Incoming/music/ server:/media/10001/music/ sync-music: get-music put-music when I make sync-music, it first gets all the diffs from server to local and then the opposite, sending all the diffs from local to server. This works very well only if there are just updates or new files on the future. If there are deletions, it doesn't do anything. In rsync there is --delete and --delete-after options to help accomplish what I want but thing is, it doesn't work on a 2-way-sync. If I want to delete server files on a syn, when local files have been deleted, it works, but if, for some reason (explained after) I have some files that aren't in the server but exist locally and they were deleted, I want locally to remove them and not server copied (as it happens). Thing is I have 3 machines in context: desktop notebook home-server So, sometimes, server will have files that were deleted with a notebook sync, for example and then, when I run a sync with my desktop (where the deleted server files still exist on) I want these files to be deleted and not to be copied again to the server. I guess this is only possible with a database and track of operations :P Any simple solutions? Thank you.

• JavaScript Exception/Error Handling Not Working

  - by Seán Hayes

  This might be a little hard to follow. I've got a function inside an object: f_openFRHandler: function(input) { console.debug('f_openFRHandler'); try{ //throw 'foo'; DragDrop.FileChanged(input); //foxyface.window.close(); } catch(e){ console.error(e); jQuery('#foxyface_open_errors').append('<div>Max local storage limit reached, unable to store new images in your browser. Please remove some images and try again.</div>'); } }, inside the try block it calls: this.FileChanged = function(input) { // FileUploadManager.addFileInput(input); console.debug(input); var files = input.files; for (var i = 0; i < files.length; i++) { var file = files[i]; if (!file.type.match(/image.*/)) continue; var reader = new FileReader(); reader.onload = (function(f, isLast) { return function(e) { if (files.length == 1) { LocalStorageManager.addImage(f.name, e.target.result, false, true); LocalStorageManager.loadCurrentImage(); //foxyface.window.close(); } else { FileUploadManager.addFileData(f, e.target.result); // add multiple files to list if (isLast) setTimeout(function() { LocalStorageManager.loadCurrentImage() },100); } }; })(file, i == files.length - 1); reader.readAsDataURL(file); } return true; LocalStorageManager.addImage calls: this.setItem = function(data){ localStorage.setItem('ImageStore', $.json_encode(data)); } localStorage.setItem throws an error if too much local storage has been used. I want to catch that error in f_openFRHandler (first code sample), but it's being sent to the error console instead of the catch block. I tried the following code in my Firebug console to make sure I'm not crazy and it works as expected despite many levels of function nesting: try{ (function(){ (function(){ throw 'foo' })() })() } catch(e){ console.debug(e) } Any ideas?

• Duplicating custom nodes in JavaFX

  - by Elazar Leibovich

  As far as I understand, duplicating nodes in JavaFX should be done with the Duplicator.duplicate function. It works fine when duplicating nodes whose types are included in JavaFX library, for example def dup = Duplicator.duplicate(Rectangle{x:30 y:30 width:100 height:100}); dup.translateX = 10; insert dup into content; would insert a black rectangle to the scene. However if I define a new class in the following way: class MyRect extends Rectangle {} Or class MyRect extends CustomNode { override function create() {Rectangle{x:30 y:30 width:10 height:10}} } It gives me the following runtime error Type 'javafxapplication1.NumberGrid$MyRect' not found. Where of course javafxapplication1.NumberGrid are the package and file the MyRect class is in. This guy at Sun's forums had the same problem, but I don't see any answer in there. Or maybe I'm doing that the wrong way, and there's a better approach for duplicating custom nodes? update: Trying to duplicate Group worked, but trying to duplicate Stack yields the same error. According to the documentation, it's supposed to support all types supported in FXD including Node, but maybe it supports only some of Node's descendants?

• A question about writing a background/automatic/silent downloader/installer for an app in C#.

  - by Mike Webb

  Background: I have a main application that needs to be able to go to the web and download DLL files associated with it (ones that we write, located on our server). It really needs to be able to download these DLL files to the application folder in "C:\Program Files\". In the past I have used System.Net.WebClient to download whatever files I wanted from the web. The Issue I have had a lot of trouble downloading data in the past and saving to files on a user's hard drive. I get many reports of users saying that this does not work and it is generally because of user rights issues in the program. In the cases where it was an issue with program user rights every user could go to the exact file location on the web, download it, and then save it to the right place manually. I want this to work like all the other programs I have seen download/install in this fassion (i.e. Firefox Pluign Updates, Flash Player, JAVA, Adobe Reader, etc). All of these work without a hitch. The Question Is there some code I need to use to give my downloader program special rights to the Program Files folder? Can I even do this? Is there a better class or library that I should use? Is there a different approach to downloading files I should take, such as using threads or something else to download data? Any help here is appreciated. I want to try to stay away from third-party apps/libraries if at all possible, other than Microsoft of course, due to licensing issues, but still send any suggestions my way. Again, other programs seem to have the rights issues and download capability figured out. I want this same capability.

• Fastest Java way to remove the first/top line of a file (like a stack)

  - by christangrant

  I am trying to improve an external sort implementation in java. I have a bunch of BufferedReader objects open for temporary files. I repeatedly remove the top line from each of these files. This pushes the limits of the Java's Heap. I would like a more scalable method of doing this without loosing speed because of a bunch of constructor calls. One solution is to only open files when they are needed, then read the first line and then delete it. But I am afraid that this will be significantly slower. So using Java libraries what is the most efficient method of doing this. --Edit-- For external sort, the usual method is to break a large file up into several chunk files. Sort each of the chunks. And then treat the sorted files like buffers, pop the top item from each file, the smallest of all those is the global minimum. Then continue until for all items. http://en.wikipedia.org/wiki/External_sorting My temporary files (buffers) are basically BufferedReader objects. The operations performed on these files are the same as stack/queue operations (peek and pop, no push needed). I am trying to make these peek and pop operations more efficient. This is because using many BufferedReader objects takes up too much space.

• Undefined Variable? But I defined it...

  - by Rob

  Well before anyone claims that theres a duplicate question... (I've noticed that people who can't answer the question tend to run and look for a duplicate, and then report it.) Here is the duplicate you are looking for: http://stackoverflow.com/questions/2481382/php-claims-my-defined-variable-is-undefined However, this isn't quite a duplicate. It gives me a solution, but I'm not really looking for this particular solution. Here is my problem: Notice: Undefined variable: custom Now here is my code: $headers = apache_request_headers(); // Request the visitor's headers. $customheader = "Header: 7ddb6ffab28bb675215a7d6e31cfc759"; //This is what the header should be. foreach ($headers as $header => $value) { $custom .= "$header: $value"; } Clearly, $custom is defined. According to the other question, it's a global and should be marked as one. But how is it a global? And how can I make it a (non-global)? The script works fine, it still displays what its supposed to and acts correctly, but when I turn on error messages, it simply outputs that notice as well. I suppose its not currently necessary to fix it, but I'd like to anyway, as well as know why its doing this.

• Photoshop CS4. How do I make sure my color stays the same in my different .psd files? (could be RGB

  - by Kris

  I asked 2 photoshop experts I know but they haven't got a clue because all my settings are exactly the same, in both files. (except the RGB type !! I'm not sure. Please read on) I use RGB color, 72DPI, 8 bits / channel. No adjustments (filters, like greyscale, etc ...) are selected / used. The layers are both normal, and opacity and fill are 100% (yes, in both files). I took two screenshots, and you can see the difference: http://www.flickr.com/photos/30465871@N05/4623864297/ http://www.flickr.com/photos/30465871@N05/4624469754/ Both colors are ff795d, but that doesn't matter, any color I use gives me the same problem: they both look different. Now, I know the CMYK settings (see screenshots) are different, but when the settings are the same the color changes. Why is this happening and how do I solve this problem? My guess is I'm working with different a type of RGB. It's sRGB IE61966 - 2.1 in the file I created (file info raw data) but I can't find that in the file that started with a screenshot. If that's the problem, how do I change / convert the RGB, once the file is already open? Thank you.

• faster way to compare rows in a data frame

  - by aguiar

  Consider the data frame below. I want to compare each row with rows below and then take the rows that are equal in more than 3 values. I wrote the code below, but it is very slow if you have a large data frame. How could I do that faster? data <- as.data.frame(matrix(c(10,11,10,13,9,10,11,10,14,9,10,10,8,12,9,10,11,10,13,9,13,13,10,13,9), nrow=5, byrow=T)) rownames(data)<-c("sample_1","sample_2","sample_3","sample_4","sample_5") >data V1 V2 V3 V4 V5 sample_1 10 11 10 13 9 sample_2 10 11 10 14 9 sample_3 10 10 8 12 9 sample_4 10 11 10 13 9 sample_5 13 13 10 13 9 tab <- data.frame(sample = NA, duplicate = NA, matches = NA) dfrow <- 1 for(i in 1:nrow(data)) { sample <- data[i, ] for(j in (i+1):nrow(data)) if(i+1 <= nrow(data)) { matches <- 0 for(V in 1:ncol(data)) { if(data[j,V] == sample[,V]) { matches <- matches + 1 } } if(matches > 3) { duplicate <- data[j, ] pair <- cbind(rownames(sample), rownames(duplicate), matches) tab[dfrow, ] <- pair dfrow <- dfrow + 1 } } } >tab sample duplicate matches 1 sample_1 sample_2 4 2 sample_1 sample_4 5 3 sample_2 sample_4 4

• DTracing TCP congestion control

  - by user12820842

  In a previous post, I showed how we can use DTrace to probe TCP receive and send window events. TCP receive and send windows are in effect both about flow-controlling how much data can be received - the receive window reflects how much data the local TCP is prepared to receive, while the send window simply reflects the size of the receive window of the peer TCP. Both then represent flow control as imposed by the receiver. However, consider that without the sender imposing flow control, and a slow link to a peer, TCP will simply fill up it's window with sent segments. Dealing with multiple TCP implementations filling their peer TCP's receive windows in this manner, busy intermediate routers may drop some of these segments, leading to timeout and retransmission, which may again lead to drops. This is termed congestion, and TCP has multiple congestion control strategies. We can see that in this example, we need to have some way of adjusting how much data we send depending on how quickly we receive acknowledgement - if we get ACKs quickly, we can safely send more segments, but if acknowledgements come slowly, we should proceed with more caution. More generally, we need to implement flow control on the send side also. Slow Start and Congestion Avoidance From RFC2581, let's examine the relevant variables: "The congestion window (cwnd) is a sender-side limit on the amount of data the sender can transmit into the network before receiving an acknowledgment (ACK). Another state variable, the slow start threshold (ssthresh), is used to determine whether the slow start or congestion avoidance algorithm is used to control data transmission" Slow start is used to probe the network's ability to handle transmission bursts both when a connection is first created and when retransmission timers fire. The latter case is important, as the fact that we have effectively lost TCP data acts as a motivator for re-probing how much data the network can handle from the sending TCP. The congestion window (cwnd) is initialized to a relatively small value, generally a low multiple of the sending maximum segment size. When slow start kicks in, we will only send that number of bytes before waiting for acknowledgement. When acknowledgements are received, the congestion window is increased in size until cwnd reaches the slow start threshold ssthresh value. For most congestion control algorithms the window increases exponentially under slow start, assuming we receive acknowledgements. We send 1 segment, receive an ACK, increase the cwnd by 1 MSS to 2*MSS, send 2 segments, receive 2 ACKs, increase the cwnd by 2*MSS to 4*MSS, send 4 segments etc. When the congestion window exceeds the slow start threshold, congestion avoidance is used instead of slow start. During congestion avoidance, the congestion window is generally updated by one MSS for each round-trip-time as opposed to each ACK, and so cwnd growth is linear instead of exponential (we may receive multiple ACKs within a single RTT). This continues until congestion is detected. If a retransmit timer fires, congestion is assumed and the ssthresh value is reset. It is reset to a fraction of the number of bytes outstanding (unacknowledged) in the network. At the same time the congestion window is reset to a single max segment size. Thus, we initiate slow start until we start receiving acknowledgements again, at which point we can eventually flip over to congestion avoidance when cwnd ssthresh. Congestion control algorithms differ most in how they handle the other indication of congestion - duplicate ACKs. A duplicate ACK is a strong indication that data has been lost, since they often come from a receiver explicitly asking for a retransmission. In some cases, a duplicate ACK may be generated at the receiver as a result of packets arriving out-of-order, so it is sensible to wait for multiple duplicate ACKs before assuming packet loss rather than out-of-order delivery. This is termed fast retransmit (i.e. retransmit without waiting for the retransmission timer to expire). Note that on Oracle Solaris 11, the congestion control method used can be customized. See here for more details. In general, 3 or more duplicate ACKs indicate packet loss and should trigger fast retransmit . It's best not to revert to slow start in this case, as the fact that the receiver knew it was missing data suggests it has received data with a higher sequence number, so we know traffic is still flowing. Falling back to slow start would be excessive therefore, so fast recovery is used instead. Observing slow start and congestion avoidance The following script counts TCP segments sent when under slow start (cwnd ssthresh). #!/usr/sbin/dtrace -s #pragma D option quiet tcp:::connect-request / start[args[1]-cs_cid] == 0/ { start[args[1]-cs_cid] = 1; } tcp:::send / start[args[1]-cs_cid] == 1 && args[3]-tcps_cwnd tcps_cwnd_ssthresh / { @c["Slow start", args[2]-ip_daddr, args[4]-tcp_dport] = count(); } tcp:::send / start[args[1]-cs_cid] == 1 && args[3]-tcps_cwnd args[3]-tcps_cwnd_ssthresh / { @c["Congestion avoidance", args[2]-ip_daddr, args[4]-tcp_dport] = count(); } As we can see the script only works on connections initiated since it is started (using the start[] associative array with the connection ID as index to set whether it's a new connection (start[cid] = 1). From there we simply differentiate send events where cwnd ssthresh (congestion avoidance). Here's the output taken when I accessed a YouTube video (where rport is 80) and from an FTP session where I put a large file onto a remote system. # dtrace -s tcp_slow_start.d ^C ALGORITHM RADDR RPORT #SEG Slow start 10.153.125.222 20 6 Slow start 138.3.237.7 80 14 Slow start 10.153.125.222 21 18 Congestion avoidance 10.153.125.222 20 1164 We see that in the case of the YouTube video, slow start was exclusively used. Most of the segments we sent in that case were likely ACKs. Compare this case - where 14 segments were sent using slow start - to the FTP case, where only 6 segments were sent before we switched to congestion avoidance for 1164 segments. In the case of the FTP session, the FTP data on port 20 was predominantly sent with congestion avoidance in operation, while the FTP session relied exclusively on slow start. For the default congestion control algorithm - "newreno" - on Solaris 11, slow start will increase the cwnd by 1 MSS for every acknowledgement received, and by 1 MSS for each RTT in congestion avoidance mode. Different pluggable congestion control algorithms operate slightly differently. For example "highspeed" will update the slow start cwnd by the number of bytes ACKed rather than the MSS. And to finish, here's a neat oneliner to visually display the distribution of congestion window values for all TCP connections to a given remote port using a quantization. In this example, only port 80 is in use and we see the majority of cwnd values for that port are in the 4096-8191 range. # dtrace -n 'tcp:::send { @q[args[4]-tcp_dport] = quantize(args[3]-tcps_cwnd); }' dtrace: description 'tcp:::send ' matched 10 probes ^C 80 value ------------- Distribution ------------- count -1 | 0 0 |@@@@@@ 5 1 | 0 2 | 0 4 | 0 8 | 0 16 | 0 32 | 0 64 | 0 128 | 0 256 | 0 512 | 0 1024 | 0 2048 |@@@@@@@@@ 8 4096 |@@@@@@@@@@@@@@@@@@@@@@@@@@ 23 8192 | 0

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.
