Mirror Image Diagonally in Python

元气小坏坏 提交于 2019-12-01 07:01:36
问题 I'm taking a programming class on python, and we're working on mirroring images by defining a mirror point and then copying a pixel from one side to the other using nested for loops. For example, mirroring an image vertically would use the following code: def mirrorVertical(source): mirrorPoint = getWidth(source) / 2 width = getWidth(source) for y in range(0,getHeight(source)): for x in range(0,mirrorPoint): leftPixel = getPixel(source,x,y) rightPixel = getPixel(source,width - x - 1,y) color

! [remote rejected] errors after mirroring a git repository

I'm following this documentation: https://help.github.com/articles/duplicating-a-repository/ git clone --mirror https://github.com/exampleuser/repository-to-mirror.git cd repository-to-mirror.git git push --mirror https://github.com/exampleuser/mirrored The output shows that the repository is pushed as a mirror, but for some reason I'm getting these errors as well: ! [remote rejected] refs/pull/1/head -> refs/pull/1/head (deny updating a hidden ref) ! [remote rejected] refs/pull/1/merge -> refs/pull/1/merge (deny updating a hidden ref) What are these errors? Can I assume the repository was

How to mirror only a section of a website?

╄→гoц情女王★ 提交于 2019-11-29 18:43:48
I cannot get wget to mirror a section of a website (a folder path below root) - it only seems to work from the website homepage. I've tried many options - here is one example wget -rkp -l3 -np http://somewebsite/subpath/down/here/ While I only want to mirror the content links below that URL - I also need to download all the page assets which are not in that path. It seems to work fine for the homepage ( / ) but I can't get it going for any sub folders. Attilio Use the --mirror ( -m ) and --no-parent ( -np ) options, plus a few of cool ones, like in this example: wget --mirror --page-requisites

Swift 2.0 Get Mirrored Superclass Properties

耗尽温柔 提交于 2019-11-29 15:04:10
I need to get the properties of my class as a dictionary. For simplicity, I created a protocol which has a default implementation as follows: protocol ListsProperties{ func toDictionary() -> [String: AnyObject] } extension ListsProperties{ func toDictionary() -> [String: AnyObject] { let mirrored_object = Mirror(reflecting: self) var dict = [String: AnyObject]() for (_, attr) in mirrored_object.children.enumerate() { if let propertyName = attr.label as String! { dict[propertyName] = attr.value as? AnyObject } } return dict } } My classes can conform to this protocol and will have the

Finding the closest Apache Software Foundation mirror programatically

为君一笑 提交于 2019-11-29 07:34:02
For my deployment automation needs, I would like to dynamically and programatically determine the closest Apache Software Foundation mirror since the servers are distributed across geographically distinct locations and it would be ideal to dynamically determine the best mirror without having to hard-code that knowledge somewhere. The only approach I could think of so far is to scrap the http://www.apache.org/dyn/closer.cgi page for the closest mirror suggested there, but it seems a bit cumbersome and fragile. Is there a web API endpoint that provides this functionality in a stable and reliable

开发加速使用maven国内源,感谢阿里技术团队,良心团队!

你说的曾经没有我的故事 提交于 2019-11-29 05:15:08
Maven阿里云中央仓库 maven作为一个项目管理工具确实非常好用,但是在国内这个网络条件下实在是让人恼火。之前oschina的中央仓库可用,现在oschina的maven服务器关了,一直没找到国内镜像来替代。 今天发现阿里云公开了一个中央仓库,大家可以试试。 配置 修改maven根目录下的conf文件夹中的setting.xml文件,内容如下: <mirrors> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> 之后就能享受如飞的maven下载速度。 来源: oschina 链接: https://my.oschina.net/u/26712/blog/790845

Make Maven Proxy/Server settings configurable based on location?

空扰寡人 提交于 2019-11-28 21:23:18
So I'm not sure what the best way to accomplish this is, but basically I have a laptop that I use at work for Maven projects. It works fine when I'm at work, but as soon as I walk out of the door of their corporate proxy and maven server, I often have to do alot of hand-fudging of the settings.xml file when I'm at home if I'm not VPN'ed in: We have a corporate-installed Maven Repository proxy server to store some of our own artifacts and handle being the middle-man for our commonly used artifacts. We have an http proxy that we use for connecting to the outside world. Both configurations have

Greenplum failed segment的恢复方法--primary与mirror都可修复

前提是你 提交于 2019-11-28 18:04:14
  当在使用greenplum过程中有不当的操作时,可能会出现segment节点宕掉的情况(比如在greenplum运行的过程中停掉其中几台segment节点的服务器),通过下面的方法可以恢复segment。 下面是现场出现的故障情况: [gpadmin@tj-soc-c04-csfb1 ~]$ gpstate -m 20161010:16:35:54:026100 gpstate:tj-soc-c04-csfb1:gpadmin-[INFO]:-Starting gpstate with args: -m 20161010:16:35:55:026100 gpstate:tj-soc-c04-csfb1:gpadmin-[INFO]:-local Greenplum Version: 'postgres (Greenplum Database) 4.3.6.2 build 1' 20161010:16:35:55:026100 gpstate:tj-soc-c04-csfb1:gpadmin-[INFO]:-master Greenplum Version: 'PostgreSQL 8.2.15 (Greenplum Database 4.3.6.2 build 1) on x86_64-unknown-linux-gnu, compiled by GCC gcc (GCC) 4

Mirror a git repository by pulling?

浪尽此生 提交于 2019-11-28 15:43:35
I am wondering if there is an easy way, ie like a simple cron job, to regularly pull from a remote git repository to a local read only mirror for backup purposes? Ideally it would pull all branches and tags, but the master/trunk/head would be sufficient. I just need a way to make sure that if the master git server dies, we have a backup location that we could manually fail over to. gregor First create a mirror with git clone --mirror git@somewhere.com:repo.git then setup a cron job like this: */1 * * * * gitbackup cd /backup/repo.git && git fetch -q --tags This will backup the changesets every
