对于HTML的学习心得

阅读更多关于对于HTML的学习心得

对于HTML的学习心得： 1.首先个人感觉HTML以及CSS，JS，jQuery等学习使比较琐碎的，对于这门课程的学习，死记硬背不太适用，需要在尝试中不断学习。学习ps的时候，老师给我们讲ps是选择的艺术，我觉得这门课程也有着选择的重要性，要在选择尝试中不断改进，使得成果更让人赏心悦目。在最后一次大作业的完成中，我们小组内就是通过不断地修改，不断地尝试完成的，虽然画面不是很美观，但是整个过程也变得更加熟练了。 2.要勤奋要勤奋要勤奋，重要的事情说三遍。只要和代码相关的东西，我觉得勤奋是必不可少的。一定要自己亲手练习，多多尝试，才会将知识记在自己的脑子里。以上两点都是个人学习后的感想，接下来还会继续分享学习过程中的心得体会。来源： CSDN 作者： xiaoxiaoyu1025 链接： https://blog.csdn.net/xiaoxiaoyu1025/article/details/103570294

Why doesn't “echo” show up in “ps”?

阅读更多关于 Why doesn't “echo” show up in “ps”?

问题 I am having great difficulty in understanding what shows up on ps command. To test my understanding I created below dummy script #!/bin/bash for i in {1..100000} do date -u date -u date -u done while running this script I opened a new terminal and executed repeatedly ps -eaf | grep date | grep -v grep and I was able to date process in the output. I later changed dummy script by replacing date -u with echo "what is going on" #!/bin/bash for i in {1..100000} do echo "What is going on" echo

How to get all process ids with memory usage greater than

阅读更多关于 How to get all process ids with memory usage greater than

问题 I need to get all process ids which have memory usage greater or lower than predifined number. For example get id where memory (rss) usage grater than 10MB and then using this id kill each process. Thanks 回答1: This following command will help I think, ps aux --sort -rss Try it. 回答2: That's not a good idea. You will certainly kill processes you should not and might render your system damaged in the process. But anyway, here's what does the trick: ps -eo rss=,pid=,user=,comm= k -rss | while

sona：Spark on Angel大规模分布式机器学习平台介绍

阅读更多关于 sona：Spark on Angel大规模分布式机器学习平台介绍

Angel是一个基于参数服务器（Parameter Server）开发的高性能分布式机器学习平台，它基于腾讯内部的海量数据进行了反复的调优。 Angel的核心设计理念围绕模型，将高维度的大模型切分到多个参数服务器节点，并通过高效的模型更新接口和运算函数，以及灵活的同步协议，轻松实现各种高效的机器学习算法。 Angel基于Java和scala开发，能在Yarn上直接调度运行，并基于PS Service，支持Spark on Angel，集成了部分图计算和深度学习算法。 Angel-PS实现了基于参数服务器的矩阵计算，将分布在多台PS Server上的参数矩阵抽象为PSModel，只需要完成PSModel的定义、实现其计算过程，就可以实现一个运行在参数服务器上的简单算法。简单的angel-ps架构如下图所示 PS是存储矩阵参数的多台机器，向计算节点提供矩阵参数的拉取、更新服务每个worker是一个逻辑计算节点，一个worker可以运行一或多个task 机器学习的算法，一般以迭代的方式训练，每次迭代worker从PS拉取最新的参数，计算一个更新值，推送给PS Angel整体架构 angel的架构分为三大模块： 1、 Parameter Server层：提供通用的参数服务器服务，负责模型的分布存储，通讯同步和协调计算，并通过PSAgent提供PS Service 2、worker层

Uninstalling MSI-Package always gives reboot message

阅读更多关于 Uninstalling MSI-Package always gives reboot message

问题 I'm just scripting something for some new software. Therefore i have to remove some older software. I'm doing this whit a PS script. This works almost fine. The elevated rights are working, the software got removed, but there is always a message from the first uninstalling concerning a reboot. This message must only be acknowledged by pressing 'OK'. Now how can I force the message not coming up? This is what I have in the PS-Script: start-process msiexec.exe -Wait -ArgumentList '/x "file.msi"

Bash - Two processes for one script

阅读更多关于 Bash - Two processes for one script

问题 I have a shell script, named test.sh : #!/bin/bash echo "start" ps xc | grep test.sh | grep -v grep | wc -l vartest=`ps xc | grep test.sh | grep -v grep | wc -l ` echo $vartest echo "end" The output result is : start 1 2 end So my question is, why are there two test.sh processes running when I call ps using `` (the same happens with $()) and not when I call ps directly? How can I get the desired result (1)? 回答1: When you start a subshell, as with the backticks, bash forks itself, then

How to display the current process tree of a bash session?

阅读更多关于 How to display the current process tree of a bash session?

问题 I would like to create a bash alias that gives me the process tree from the current bash session I am using, up to init. The use case is to know whether I have used bash or vi 's :shell command. I am using MacOS X. I have heard about pstree , but it seems to only show children, not the relationship between init and the current process. 回答1: I am sure with a a bit of google search, you can find how to get and download pstree for the Mac. However, you can do a poor man's version, using ps and
