我跑了docker images,得到这样的东西:

REPOSITORY                       TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
docker.io/postgres               latest              a7d662bede59        2 weeks ago         265.3 MB
docker.io/ubuntu                 latest              91e54dfb1179        2 weeks ago         188.3 MB

看看CREATED专栏.我想知道之前用小时,分钟,秒创建的图像.与容器类似,用于命令docker ps -a.如何查看确切日期？

今天我第一次在Fedora 21上安装了docker.现在,我需要从默认的/ var/lib/docker更改docker images文件夹的位置.

复制文件(跳过devicemapper子文件夹,停止停止服务器)和更改/ etc/sysconfig/docker(添加-g选项)后,我再次运行docker service,没有问题,devicemapper/metadata创建.

接下来,我试图拉第一张图片:

docker pull centos

但是发生了这个错误:

docker pull centos
latest: Pulling from docker.io/centos

编译gcc 4.6.2时出现问题:

在我的gcc-4.6.2/avr/libgcc/config.log中,我发现:

我可以在哪里下载使用itextsharp的C#示例？链接http://sourceforge.net/p/itextsharp/code/HEAD/tree/tutorial/signatures/已被破解(对我来说最有趣的是签名).

来自http://support.itextpdf.com/node/178的所有链接都不起作用.

我使用 Visual Studio 分析器来查找页面中速度较慢的地方，每次分析后都会分析报告。通过输出窗口和 Fiddler，我看到它尝试查找 ntdll.dll、kernel32.dll、iiscore.dll 等的符号。在 Fiddler 中，我看到大约 100 次尝试加载如下 URL：

http://srv.symbolsource.org/pdb/Public/iisutil.pdb/FD34931572094C6E9FD7444A2C3600E92/iisutil.pdb http://srv.symbolsource.org/pdb/Public/iisutil.pdb/FD34931572094C6E9FD7444A2C3600E92/iisutil 。 PD_

结果 - 404。每次。

因此，我用 1 分钟介绍我的申请，然后等待 5 分钟。如何修复它以加载正确的 pdb，或跳过加载第 3 方 pdb？

我需要重新编译java应用程序,在Java 8上编写.App使用com.sun.javafx.collections.ObservableListWrapper类,但在编译java 9时出现错误:

Error:(3, 22) java: package com.sun.javafx.collections is not visible
  (package com.sun.javafx.collections is declared in module javafx.base,     which does not export it to the unnamed module)

我可以使用哪个班而不是ObservableListWrapper？或者如何绕过这个问题？
