server

搞过android开发的人应该都有遇到eclipse装怪的时候吧，反正我有几次就想扔砖头砸电脑。下面是我遇到的几个常见的问题： 1：ADB server didn't ACK failed to start daemon ，这个是我遇到过最多的问题， [2012-08-31 10:40:37 - GPS] The connection to adb is down, and a severe error has occured. [2012-08-31 10:40:37 - GPS] You must restart adb and Eclipse. [2012-08-31 10:40:37 - GPS] Please ensure that adb is correctly located at 'D:\Program Files\Android\android-sdk\platform-tools\adb.exe' and can be executed. 网上有说一些方法，比如说在任务管理器里面关闭adb.exe，再重启eclipse，或者重启电脑，但是我发现有一个很有可能解决问题的方法。因为大家做android开发嘛，或多或少会使用真机开发，就很可能会使用豌豆荚这个软件，然后在你连接上电脑以后，虽然有时候豌豆荚没有打开

最近对SQL Server到PostgreSQL的数据迁移时出现了问题，返回的错误为：invalid byte sequence for encoding "UTF8": 0x00。 经查证 pg 源代码，该问题引起的原因是 sql server 的字符类型字段中含有空字符 \0 ，该字符在 pg 中不支持。 问题重现： 1、PG客户端: postgres=# create table text_test (id int,info text); CREATE TABLE postgres=# insert into text_test values (1,E'\0x00'); ERROR: invalid byte sequence for encoding "UTF8": 0x00 2、SQL Server产生数据 create table test_varchar(id int,name varchar(20)); insert into test_varchar values (1, 'name' + char(0)); insert into test_varchar values (1, 'name' + ''); 然后通过java程序进行获取数据并插入到PG，同样会得到错误信息： invalid byte sequence for encoding "UTF8":

I have webapp with firebase database. I would like hosting the app on firebase. My app has own server nodejs and using websockets. How can I host my app on Firebase? And how can I run my own server on Firebase? I think your question is quite simple. And the answer is also simple: no, you can't. Firebase only serves static files. You need to try heroku, codeship, etc for that. I'm not sure what exactly you are looking for. I'll assume it's one of these two: you want to run the node.js scripts on Firebase's server There is no way to run your own code on Firebase's servers. you want to run the

Anyone have idea to host site or reference for how to install node server on Godaddy. Yes this is possible . Somehow I have never seen anyone actually answer this question correctly. This works with the most basic shared hosting plans. I have successfully been able to set it up a couple different ways. I think the second is probably what you want : 1. cgi-node http://www.cgi-node.org/home Basically this replaces PHP on the lamp stack. You can run javascript through node like you would run PHP. This has all the same functionality of node js but is only really geared towards template rendering.

1.介绍 Hibernate是目前最为常用的ORM框架,当然也有人会选择iBATIS或者其他的架构.这里我们着重讲Hibernate的ID生成策略 2.可选的ID策略生成方式 (1)native/auto 根据不同的数据库采用不同的ID生成方式,例如:在SQL Server中采用identity; 在MySQL中采用auto_increment; 在ORACLE中就会采用sequence, 注意hibernate会自动帮你创建一个名字叫hibernate_sequence的序列,不用自己去创建.这也是最常用和省事的. 例子 :采用xml方式配置 <hibernate-mapping> <class name="abu.csdn.bean.User" table="users"> <id column="uid" name="uid" type="java.lang.Long"> <generator class="native"/> </id> ..... </class> <hibernate-mapping> 例子 :采用注解方式(注意只要在id的getter上写上@Id就可以了,默认就是@GeneratedValue(strategy = GenerationType.AUTO), 另外(strategy = GenerationType.AUTO)也可以不写.
