I have a webserver written in go and I'm serving some audio files from different sources (local, other servers, S3). I want to enable serving partial content for this files so the HTML audio tags are able to seek and loop. How can I achive this? I know that the http package ServeContent function does this but how can I do it by serving the files myself? I need to do it without this so that I can serve files from different sources with the same handler. Serving partial content is non-trivial. See Byte serving on wikipedia for an introduction. You have to handle specific status codes and headers

I'm trying to adapt the example provided here for Smack 4.1.0. and getting a little confused. Specifically I'm struggling to understand what the GcmPacketExtension should now extend, how the constructor should work and how the Providermanager.addExtensionProvider should be updated to tie in with it. I'm sure someone must have done this before but I can't find any examples and I seem to be going round in circles using just the documentation. Any help would be much appreciated, I'm sure the answer is very simple! Current Code (is compiling but not running): static { ProviderManager

注意，本文告诉你如何更好的用pdo连接sql server 2005 而不是 2000。(MSSQL2000可以直接应用PHP内置函数或直接调用PDO，另外如果应用PDO连接MSSQL 2000，需要将PHP 文件目录下的ntwdblib.dll文件复制到系统system32文件目录下，之后重启Apache服务器，利用phpinfo()函数查看DLL是 否加载成功) 废话不多说，只说重点，按步骤来： 1. 确保正确安装sql server 2005 ， 开启sql server的远程连接访问，检查防火墙，确认在本地可以通过SQL Server Configuration Manager连接到服务器。 2. 修改 php.ini 开启相关扩展(php_pdo.dll ，php_pdo_mssql.dll ，php_mssql.dll)，重启apache后，一定要用phpinfo()检查是否成功加载。 3. 修改php.ini中：mssql.secure_connection = Off ，网上很多人说改为On，那是扯淡，改为Off就对啦。 4. (重点) 如果是连接sql server 2000，只需要把php根目录下的ntwdblib.dll文件copy到apache/bin/或者windows/system32/， 但是连接 sql server 2005 必须使用2000.80

I'm trying to learn Go web programming, and here is a simple web server: it prints out the times being called. package main import ( "fmt" "net/http" ) var calls int // HelloWorld print the times being called. func HelloWorld(w http.ResponseWriter, r *http.Request){ calls++ fmt.Fprintf(w, "You've called me %d times", calls) } func main() { fmt.Printf("Started server at http://localhost%v.\n", 5000) http.HandleFunc("/", HelloWorld) http.ListenAndServe(":5000", nil) } When I refresh the page, I got: You've called me 1 times You've called me 3 times You've called me 5 times .... Question: Why it

I have tried and tried, and can not get linked. I can connect to the server using SSMS, but can not link to it from a local server. Here is my script (replacing things in brackets with pertainent information): EXEC master.dbo.sp_addlinkedserver @server = N'[servername].database.windows.net', @srvproduct = N'Any', @provider = N'MSDASQL', @datasrc = N'Azure_ODBC1' GO EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname = N'[servername]', @useself = N'False', @locallogin = NULL, @rmtuser = N'[username]', @rmtpassword = '[password]' GO As specified in ckarst second link, there is a solution that works

I'm looking for a way to handle a disconnect, because every time I close a client, the server stops working. I get an error message, that it is "unable to read beyond the end of the stream" in this line: string message = reader.ReadString(); Also I need a way to delet the disconnected client from the clients list. Here is my code: Server using System; using System.Threading; using System.Net.Sockets; using System.IO; using System.Net; using System.Collections.Generic; namespace Server { class Server { public static List<TcpClient> clients = new List<TcpClient>(); static void Main(string[] args
