性能调优工具-火焰图

阅读更多关于性能调优工具-火焰图

前言工具的进化一直是人类生产力进步的标志，合理使用工具能大大提高我们的工作效率，遇到问题时，合理使用工具更能加快问题排查的进度。这也是我为什么非常喜欢 shell 的原因，它丰富的命令行工具集加管道特性处理起文本数据集来真的精准而优雅，让人迷醉。但很多时候文本的表现力非常有限，可以说匮乏，表达绝对值时，自然是无往不利，但在展示相对值时，就有些捉襟见肘了，就更不用说多维数据了。我们用 shell 可以非常快速地查询出文本内的累加值、最大值等，但一遇到两组值的相关性分析时，就束手无策了。这个时候，就需要使用另一种分析工具 – 图了，如散点图就能很清晰地展示相关性。今天就准备介绍一种图，火焰图，之前组内大神分享过它的使用办法，但我之后很久都没有用过，以至于对它没有什么深刻印象，最近排查我们 Java 应用负载问题时试用了一下，这才对它的用途有了点心得。转载随意，文章会持续修订，请注明来源地址： https://zhenbianshu.github.io 。介绍引子在排查性能问题时，我们通常会把线程栈 dump 出来，然后使用 grep --no-group-separator -A 1 java.lang.Thread.State jstack.log | awk 'NR%2==0' | sort | uniq -c | sort -nr 类似的 shell 语句

Text Summarization Evaluation - BLEU vs ROUGE

阅读更多关于 Text Summarization Evaluation - BLEU vs ROUGE

问题 With the results of two different summary systems (sys1 and sys2) and the same reference summaries, I evaluated them with both BLEU and ROUGE. The problem is: All ROUGE scores of sys1 was higher than sys2 (ROUGE-1, ROUGE-2, ROUGE-3, ROUGE-4, ROUGE-L, ROUGE-SU4, ...) but the BLEU score of sys1 was less than the BLEU score of sys2 (quite much). So my question is: Both ROUGE and BLEU are based on n-gram to measure the similar between the summaries of systems and the summaries of human. So why

阅读更多关于 GitHub Pages mangling syntax highlighting after upgrade to Jekyll 3

问题 I use Github Pages for my personal website. They're upgrading from Jekyll 2 to Jekyll 3 and sending deprecation warnings. I complied with their warnings and switched from redcarpet to kramdown and from pygments to rouge. When I build locally (with bundle exec jekyll serve ) everything works. But when I push the changes the syntax highlighting gets mangled wherever I have linenos in my code blocks. This is the code block: {% highlight python linenos %} ''' scrape lyrics from vagalume.com.br

阅读更多关于 Rouge gem not showing line breaks in formatted code?

问题 I have followed minimal examples using the rouge gem here (i.e. the documentation), as well as here and here. Everything working, except that line breaks in the code aren't appearing. To be explicit, code like this def plus_two(x) x + 2 end has the colours highlighted correctly, but is rendered across one line, like so def plus_two(x) x + 2 end How can I make it render with the line breaks (just as in the code file) 回答1: Change require 'rouge' source = "def plus_two(x)\n x + 2\nend" formatter
