假设我们得到了以下信息:
/agents <--returns all agents
/agents/5 <-- returns data for agent id 5
/agents/5/status <-- returns status for agent 5
我如何编写一个RESTful URI来获取所有代理的状态?拥有一个/status是不行的,因为其他资源也有状态。我想要的是:
/agents/*/status <-- never seen this
但找不到类似的东西。现在我有一个:
/misc/agentsstatus <-- not pretty
在Linux (amd64)上,我从管道中读取一些相关进程的数据。我希望确保读取的字节不被更改,并防止隐式类型和值转换。
当我将数据放入char或无符号char数组(请参阅#ifdef)时,是否应该使用vector<>对从子节点读取的数据进行类型转换?如果我使用一个不同的平台,比如arm (raspi/beaglebone),会发生什么?转换会在std::back_inserter发生吗?
#ifdef USE_UCHAR
using buffer_type = unsigned char;
#else
using b

我试图用特定的模块运行redis服务器(在CentOS服务器上):
redis-server --loadmodule ./redisql_v0.9.1_x86_64.so
并得到错误:
Module ./redisql_v0.9.1_x86_64.so failed to load: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by ./redisql_v0.9.1_x86_64.so)
这是linux版本:

我有下面的模型
public class Locale
{
public int Id { get; set; }
public ICollection<Localization<Locale>> Localizations { get; set; }
}
public class Localization<T>
{
public int Id { get; set; }
public Locale Locale { get; set; }
public string DisplayName { get; set;
在阅读aho的《数据结构》一书中关于集合的基本操作的章节时,我在主题bit vector implementation of sets中遇到了下面这行:
if the universal set is sufficiently small so that a bit vector fits in one computer word,
then union, intersection and difference can be performed by single logical operations in
the language of the underlying machine..
我正在仔细阅读在线书籍“计算类别理论”,在这本书中我遇到了一些问题2.10。特别是关于powerset的定义。
abstype 'a Set = set of 'a list
with val emptyset = set([])
fun is_empty(set(s)) = length(s)=0
fun singleton(x) = set([x])
fun disjoint_union(set(s),set(nil))=set(s) |
disjoint_union(set(s),set(t::y))=
