我希望这可以让使用破折号的风格让人头疼,特别是因为bootstrap已经变得如此受欢迎.

我正在使用角度1.0.5

<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>

在ngClass文档中,示例很简单,但它也提到表达式可以是类名到布尔值的映射.我试图在我的图标上使用"icon-white"样式,如引导文档中所示,具体取决于布尔变量.

<i class="icon-home" ng-class="{icon-white: someBooleanValue}">

上面的行不起作用.icon-white如果someBooleanValue为true,则不附加该类.但是,如果我将密钥更改为iconWhite,则会成功将其添加到类值列表中.如何用破折号添加值？

使用Kafka 0.8.1.1,如何在运行时更改日志保留时间？该文件说,财产是log.retention.hours,而是试图用它来改变kafka-topics.sh返回此错误

$ bin/kafka-topics.sh --zookeeper zk.yoursite.com --alter --topic as-access --config topic.log.retention.hours=24

我正在使用kafka_2.9.2-0.8.1.1和zookeeper 3.4.6.

是否有可以从zookeeper中自动删除使用者组的实用程序？或者我可以删除zookeeper中/ consumers/[group_id]下的所有内容吗？如果是后者,还有什么我错过了吗？这可以用现场系统完成吗？

我很难logback从我的2.3.8试运行中排除.我尝试了许多排除规则,但似乎没有任何效果.我也在我的依赖树中找不到它.来自我的sbt文件的片段:

我正在使用kafka 0.8.2并且我的一个kafka服务器已经死亡(无法恢复磁盘上的数据).复制为1的主题与死服务器上的一个分区有关.我认为重新分配会将该分区的元数据移动到新服务器而不需要数据,但重新分配仍然存在in progress.

我跑了:

$ /opt/kafka/kafka/bin/kafka-reassign-partitions.sh --zookeeper myzookeeper.my.com --reassignment-json-file new_assignment.json --verify
Status of partition reassignment:
Reassignment of partition [topicX,1] is still in progress

这将永远不会成功,因为死服务器永远不会回来.

在新服务器的日志中,我看到:

[2015-05-28 06:25:15,401] INFO Completed load of log topicX-1 with log end offset 0 (kafka.log.Log)
[2015-05-28 06:25:15,402] INFO Created log for partition [topicX,1] in /mnt2/data/kafka with properties {segment.index.bytes -> 10485760, file.delete.delay.ms -> 60000, segment.bytes -> 536870912, flush.ms -> 9223372036854775807, delete.retention.ms -> 86400000, index.interval.bytes -> 4096, retention.bytes -> -1, min.insync.replicas -> 1, cleanup.policy -> delete, …

是否有一个链码填充函数，我可以用它来检索 Hyperledger Fabric 链码中世界状态的所有键（可能包括值）？

我在 Debian Docker 映像上使用 python 3.6 和 pdfkit 0.6.1（似乎是 wkhtmltopdf 0.12.3.2）。我尝试查看docs & wkhtmltopdf 选项，但无法指定整个文档的字体。只有页脚和页眉的字体选项。

我尝试指定

font-family: "Times New Roman", Times, serif;

在html 到 pdf 转换之前的divhtml<style>部分的包装器中，但它没有出现“Times New Roman”。查看二进制文件，似乎它正在使用DejaVuSerif.

有没有办法指定正在转换的文档的字体？

这个问题似乎已经回答了之前,但因为testacular组不存在了链接不存在了.即使我的搜索功能适中,我也无法在角度组中找到任何跳过测试的参考.

我在config/karma-e2e.js中的配置文件:

basePath = '../';

files = [
  JASMINE, JASMINE_ADAPTER,
  'app/assets/javascripts/v2/vendor/angular.1.0.5.js',
  'app/assets/javascripts/v2/vendor/angular-*.js',
  'karma/lib/angular/angular-scenario.js',
  'karma/lib/angular/angular-mocks.js',
  'app/assets/javascripts/v2/vendor/*.js',
  'app/assets/javascripts/v2/services/*.js',
  'app/assets/javascripts/v2/controllers/*.js',
  'app/assets/javascripts/v2/*.js',
  'karma/e2e/*.js'
];

autoWatch = true;

browsers = ['Chrome'];

singleRun = true;

proxies = {
  '/': 'http://localhost:3000/'
};

junitReporter = {
  outputFile: 'test_out/e2e.xml',
  suite: 'e2e'
};

我的应用程序正在(rails)端口3000上提供.我的测试尽可能简单.它看起来像这样:

'use strict';

describe("A suite", function() {
  beforeEach(function() {
    browser().navigateTo('/');
  });

  it("contains spec with an expectation", function() {
    expect(true).toBe(true);
  });
});

这个测试被跳过了!

我正在关注独立服务器v2.1.1的Cassandra网站上的教程.我试图让它在一个流浪的实例上运行.JDK版本是java version "1.7.0_72".即使我开始使用Cassandra sudo bin/cassandra -f,我也会收到此错误:

已创建CommitLog文件,但服务器仍处于停止状态.

我能做些什么来让cassandra运行？

我正在使用kafka_2.9.2-0.8.1.1和zookeeper 3.4.6.

有没有办法动态更改代理配置设置？具体来说,我想改变controlled.shutdown.enable

bin/kafka-topics.sh --zookeeper zookeeper01.mysite.com --config controlled.shutdown.enable=true --alter

但我得到了错误

Missing required argument "[topic]"

在信封发出后,有没有办法阻止签名者在签名时更改姓名？

基本上,我希望用户的名称在整个过程中保持不变.我正在使用API​​来创建信封,所以也许API调用中有什么东西？
