A behavior like that seems like it should be opt-in. What exactly is the benefit of having to manually freeze a frozen object's objects recursively? If I'm freezing an object, why would I want the objects inside of it to still be mutable? 回答1: The answer lies in the point itself Note that values that are

However whenever I get to the $.plot point it freezes IE8 and it takes forever to load that many points. Here is my code: var data = []; function onDataReceived(seriesData) { var p = $.plot(placeholder, seriesData.seriesData, options); } $.ajax({ url: '/Charts/LineChart?DataTypesToGraph=' + dataTypes + '&DatePull=' + chartDate +

See Tools/freeze/ for now. http://docs.python.org/library/imp.html#imp.init_frozen I don't get it. What is the freeze utility? How can it be used? Why would it be used? 回答1: This link explains what the Python Freeze utility is in detail: http://wiki.python.org/moin/Freeze In a nutshell, it creates a portable version of a python script that carries its own built

Then I launch another process, where I call a graph function that is regularly updated. Up this point, eveything works fine. Then when I try to launch another process with the SAME graph function, it freeze my whole computer, BUT the background processes stil work... I only have one of these errors (it's not always the same): error 1 : XIO: fatal IO error 25 (Inappropriate ioctl for device) on X

We recently had a situation where one of our production JVMs would randomly freeze. The Java process was burning CPU, but all visible activity would cease: no log output, nothing written to the GC log, no response to any network request, etc. The process would persist in this state until restarted. It turned out that the org.mozilla.javascript.DToA class, when invoked on certain inputs, will get confused and call BigInteger.pow with enormous values (e.g. 5^2147483647), which triggers the JVM freeze. My guess is that some large loop, perhaps in java.math.BigInteger.multiplyToLen, was JIT'ed

方法1：pip list 方法2：pip freeze 这两个同时适用于Windows和Linux系统 当 pip版本过低 时，会出现list命令不存在，且freeze命令报错的情况。Eg： 有些Linux系统自带的Python环境所对应的pip版本为1.0.2，如下图所示： 在该环境下执行pip list，报 pip: error: No command by the name pip list 错误，如下图所示： 执行pip help可以发现，可执行命令中没有list，如下图所示： 执行pip freeze，错误提示如下图所示： 将pip升级为最新版本即可； 命令： pip install --upgrade pip -i https://pypi.mirrors.ustc.edu.cn/simple 然后执行pip list 或 pip freeze均可实现依赖及版本号查看。 文章来源: 查看Python依赖包及其版本号信息――Linux、Windows均适用

I'm new to Magical Record, but already have seen a few questions on stackoverflow, and can't find an answer to my question. I have to find items with the predicate using this type of construction: NSArray *result = [MOSomeItems MR_findAllWithPredicate:predicate]; On the main thread result returns some value, but the UI is freezing. When using this construction, result returns nil value: dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{ NSArray *result = [MOSomeItems MR_findAllWithPredicate:predicate]; }); What is the best practice for fetching data in

I am using java + AndEngine in my game. During the game i have some freezes, i looked for the information and found some steps how to optimize game performance: Avoid GC (garbage collector) to be called in main action in the game: a)don't create objects while gaming; b)don't create unnecessary objects; Optimize code that repeats very often I followed these steps, but never the less i have some freezes during the gameplay. Now i am creating and loading all of the textures before the game started and don't unload them, is it a bad idea ? How can i optimize the game proccess ? Maybe i have to
