请告诉我如何在apk包中保护我们的资源.通过简单的重命名提取过程,任何人都可以复制和窃取应用程序可绘制资源,如图像或soundFX文件.我的问题是,有没有办法保护Android应用程序中的可绘制资源？
List<Pair<String, String> > lp = new ArrayList<Pair<String, String> >();
lp.add(new Pair("1", "2"));
我应该如何检查列表lp是否包含1和2,即对("1","2").
我正在开发一个eclipse插件,它将某个Editor与特定的文件扩展名相关联,比如".abc".
问题是我想将.abc文件与该编辑器关联,仅用于我自己的项目.就像现在一样,无论在哪个项目中,它都将始终使用该编辑器打开.abc文件.
如果".abc"文件属于我自己的项目,我该如何打开自己的编辑器呢？
如果我有一个等于url的字符串"output":
${output} = "/testing/method/thing.do?foo=testing&bar=foo"
在jsp中,我如何将该字符串转换为:
%2Ftesting%2Fmethod%2Fthing.do%3Ffoo%3Dtesting%26bar%3Dfoo
运用
<c:out value="${output}"/>
？我需要以某种方式在c:out中使用URLEncoder.encode(url).
我有一个跨平台的应用程序,我们使用ant在不同的平台上构建不同的东西.现在出现了一个新的要求,如果在Snow Leopard或者后来的Leopard上进行构建,我需要采取不同的做法.
我查看了http://www.devdaily.com/blog/post/java/how-determine-operating-system-os-ant-build-script,其中介绍了如何区分Windows和Macintosh等,以及http ://www.jajakarta.org/ant/ant-1.6.1/docs/en/manual/api/org/apache/tools/ant/taskdefs/condition/Os.html显示了os的其他属性,例如${os.version}.
我还没想到的是如何比较它的os.version价值,如果它是10.6或更高的雪豹的东西.如果我可以snow_leopard在Snow Leopard上将变量设置为1,我想我可以将其余部分计算出来.
通过Pusher和Beacon推送云服务,我可以在所有浏览器中获得实时更新.甚至实现聊天功能.
难道这些云服务无法替代我学习XMPP/AMQP/Websockets/Comet来实现相同类型的实时更新/提要吗？
我现在已经对这个错误进行了12小时的故障排除,我认为我已经将此范围缩小到了这一点.
如果我提供post方法,无论是json对象还是字符串,IE将允许最多约3926个字符.没有其他任何东西,无论它的形状或大小如何.只要它像这样传递:

在所有其他浏览器中,这完全没有问题.但IE不会容忍过去某一点.
有没有人知道我可以通过在一个小的和浓缩的方式,甚至在一个替代办法相同的数据量？
另一种,我在想,这样的对象本身控制器之间传递,但可以通过对象的别名不通过的意见.无需将对象保存到数据库即可完成此操作.只是在这里大声思考.
对任何想法开放.:d
我的哈姆尔:
= form_tag generate_csv_path(:calc => @calc.results, :total_interest => @calc.total_interest, :per_diem => @calc.per_diem, :docket_num => @calc.docket_num, :our_file_num => @calc.our_file_num) do
= submit_tag 'Print CSV', :id => "print_csv"
UPDATE
所以我正在遍历所有试图将它们分解成更小的隐藏字段的项目,它们都是以哈希的形式出现的
- @calc.results.each do |k, v|
= hidden_field :calc_result, "#{k[:total_interest]}"
生产:
"117.68"=>"",
"166.26"=>"",
"147.1"=>"",
"107.58"=>"",
"58.68"=>"",
令人难以置信的奇怪......我想我最终可能会创建一个哈希值.这样1个calc_result就可以有5个不同的属性.
我在翻译中做了这一切......
loc1 = '/council/council1'
file1 = open(loc1, 'r')
此时我可以执行file1.read()并将文件的内容作为字符串打印到标准输出
但如果我加上这个..
string1 = file1.read()
字符串1回来了空..我不知道我可能做错了什么.这似乎是最基本的东西!
如果我继续再次输入file1.read(),则输出到标准输出只是一个空字符串.所以,当我尝试使用file1.read()创建一个字符串时,我失去了我的文件
我有一个格式的字符串
[00:26:19] Completed 80000 out of 500000 steps (16%)
从中我想得到这个16部分.
我应该搜索(然后获取%并获得介于两者之间的部分,还是设置正则表达式查询更明智？
听说科学计算项目(恰好是这里描述的随机纤维束成像方法)我目前正在为一名研究人员运行,我们的50个节点集群需要4个月,研究人员要求我检查其他选项.该项目目前正在使用并行python将4d数组的块分配到不同的集群节点,并将处理后的块重新组合在一起.
我目前正在处理的工作可能过于粗糙,(5秒到10分钟,我不得不在并行python中增加超时默认值)并且我估计通过重写它可以将进程加速2-4倍为了更好地利用资源(将数据拆分和重新组合在一起花费的时间太长,也应该并行化).大部分工作都是由numpy数组完成的.
我们假设2-4次是不够的,我决定从我们的本地硬件中获取代码.对于像这样的高吞吐量计算,我的商业选择是什么以及如何修改代码？
