Lazy Load on MULTIPLE horizontal containers

ぐ巨炮叔叔 提交于 2019-12-07 04:04:25
I'm using Lazy Load jQuery plugin: http://www.appelsiini.net/projects/lazyload My question is: is it possible to have multiple scrolling containers each with a lazyload images inside, like this: $("#container1 img.lazy").lazyload({ container: $("#container1")}); $("#container2 img.lazy").lazyload({ container: $("#container2")}); When I do this it seems to only keep track of the most recently called. I tried to call the function two times (one for each container) but it didn't work, I also tried to call both containers this way: container: $("#container1, #container2")}); and didn't work either

kubernetes之单 pod 多容器的疑难杂症 最近在学习 kubernetes 的单 pod 多容器,找了几个实例,自己测试【 单pod 双容器 】,总是 只有一个 running , 另一个一直在 created 和 started , 看了日志没发现什么问题。 而且配置是按照官网的修改的,不知是 yaml 写错了(大概率),还是 kube 需要修改什么配置,如有哪位大神测试成功,麻烦指点一二。 官网的例子: apiVersion: v1 kind: Pod metadata: name: www spec: containers: - name: nginx image: nginx volumeMounts: - mountPath: /srv/www name: www-data readOnly: true - name: git-monitor image: kubernetes/git-monitor env: - name: GIT_REPO value: http://github.com/some/repo.git volumeMounts: - mountPath: /data name: www-data volumes: - name: www-data emptyDir: {} [root@www pod_nginx_redis_kube]#

How to copy List to Array

孤人 提交于 2019-12-07 01:26:25
问题 I have list of Guid's List<Guid> MyList; I need to copy its contents to Array Guid[] Please recommend me a pretty solution 回答1: As Luke said in comments, the particular List<T> type already has a ToArray() method. But if you're using C# 3.0, you can leverage the ToArray() extension method on any IEnumerable instance (that includes IList , IList<T> , collections, other arrays, etc.) var myList = new List<Guid> {Guid.NewGuid(), Guid.NewGuid()}; Guid[] array = myList.ToArray(); // instance

should std::vector honour alignof(value_type)?

左心房为你撑大大i 提交于 2019-12-07 00:01:18
问题 If I define a simple type with a certain alignment requirement, shouldn't a std::vector<t> of said type honour the alignment for every single element ? Consider the following example typedef std::array<double,3> alignas(32) avx_point; std::vector<avx_point> x(10); assert(!(std::ptrdiff_t(&(x[0]))&31) && // assert that x[0] is 32-byte aligned !(std::ptrdiff_t(&(x[1]))&31)); // assert that x[1] is 32-byte aligned I found that the alignment requirement is silently (without any warning) violated

一曲冷凌霜 提交于 2019-12-06 23:45:30
My objective is to scrape the web with Selenium driven by Python from a docker container . I've looked around for and not found a docker image with all of the following installed: Python 3 ChromeDriver Chrome Selenium Is anyone able to link me to a docker image with all of these installed and working together? Perhaps building my own isn't as difficult as I think, but it's alluded me thus far. Any and all advice appreciated. Try https://github.com/SeleniumHQ/docker-selenium . It has python installed: $ docker run selenium/standalone-chrome python3 --version Python 3.5.2 The instructions

docker-compose: redis connection refused between containers

风格不统一 提交于 2019-12-06 19:37:42
问题 I am trying to setup a docker-compose file that is intended to replace a single Docker container solution that runs several processes (RQ worker, RQ dashboard and a Flask application) with Supervisor. The host system is a Debian 8 Linux and my docker-compose.yml looks like this (I deleted all other entries to reduce error sources): version: '2' services: redis: image: redis:latest rq-worker1: build: . command: /usr/local/bin/rqworker boo-uploads depends_on: - redis "rq-worker1" is a Python RQ

Execute mongodb binaries on alpine linux

元气小坏坏 提交于 2019-12-06 19:26:49
问题 I'm trying to run the binary mongodb in Alpine 64bit Linux for a docker container. But when running the command: ./mongodb the following error occurs: bash-4.3 # ./mongod bash: ./mongod: No such file or directory. For what reason it can not run it? 回答1: If you are still needing to use a package then there is now one available in the testing repository you can have a try with. http://dl-3.alpinelinux.org/alpine/edge/testing/x86_64/ echo 'http://dl-3.alpinelinux.org/alpine/edge/testing' >> /etc

Finding any element with specific first coordinate in set<pair> >

你离开我真会死。 提交于 2019-12-06 19:14:04
问题 I'm trying to figure out the following problem. Suppose I have the following container in C++: std::set<std::pair<int, int> > my_container; This set (dictionary) is sorted with respect to the order < on std::pair<int, int> , which is the lexicographic order. My task is to find any element in my_container that has the first coordinate equal to, say x , and return the iterator to it. Obviously, I don't want to use find_if , because I need to solve this in logarithmic time. I would appreciate

Copy folder with wildcard from docker container to host

问题 Creating a backup script to dump mongodb inside a container, I need to copy the folder outside the container, Docker cp doesn't seem to work with wildcards : docker cp mongodb:mongo_dump_* . The following is thrown in the terminal : Error response from daemon: lstat /var/lib/docker/aufs/mnt/SomeHash/mongo_dump_*: no such file or directory Is there any workaround to use wildcards with cp command ? 回答1: You can create the mongo dump files into a folder inside the container and then copy the

Can a reference type be used as the key type in an STL map

拟墨画扇 提交于 2019-12-06 17:01:21
问题 Can I construct an std::map where the key type is a reference type, e.g. Foo & and if not, why not? 回答1: According to C++ Standard 23.1.2/7 key_type should be assignable. Reference type is not. 回答2: No, because many of the functions in std::map takes a reference to the keytype and references to references are illegal in C++. /A.B. 回答3: Consider the operator[](const key_type & key) . If key_type is Foo & then what is const key_type & ? The thing is that it does not work. You can not construct
