How does one implement FxCop / static analysis on an existing code base

由 给你一囗甜甜゛ 提交于 2019-12-18 16:56:21
问题 What are some of the strategies that are used when implementing FxCop / static analysis on existing code bases with existing violations? How can one most effectively reduce the static analysis violations? 回答1: Make liberal use of [SuppressMessage] attribute to begin with. At least at the beginning. Once you get the count to 0 via the attribute, you then put in a rule that new checkins may not introduce FxCop violations. Visual Studio 2008 has a nice code analysis feature that allows you to

Eclipse plugin for measuring lines of code

由 社会主义新天地 提交于 2019-12-18 13:10:21
问题 I'm running Eclipse Helios (3.6) and was wondering if there is a nice plugin out there that will count the number of logical lines of code in a java source file. By logical, I mean if (j > 6) { j--; } In other words, 2 logical lines of code (2 statements) will be counted instead of 3 physical lines of code. 回答1: Metrics2 is an updated version of the Metrics plug-in described by js3v that should do what you need. It can also aggregate some of the measurements (e.g. add up the LOC of classes in

Seeking clarifications about structuring code to reduce cyclomatic complexity

由 。_饼干妹妹 提交于 2019-12-18 11:22:08
问题 Recently our company has started measuring the cyclomatic complexity (CC) of the functions in our code on a weekly basis, and reporting which functions have improved or worsened. So we have started paying a lot more attention to the CC of functions. I've read that CC could be informally calculated as 1 + the number of decision points in a function (e.g. if statement, for loop, select etc), or also the number of paths through a function... I understand that the easiest way of reducing CC is to

Calculate distance between colors in HSV space

由 二次信任 提交于 2019-12-17 18:44:51
问题 I intend to find a distance metric between two colours in HSV space. Suppose that each colour element has 3 components: hue, saturation, and value. Hue is ranged between 0 to 360, saturation is ranged between 0 to 1, and value is ranged between 0 to 255. Also hue has a circular property, for example, 359 in hue is closer to 0 in hue value than 10 in hue. Can anyone provide a good metric to calculate the distance between 2 colour element in HSV space here? 回答1: First a short warning: Computing

SSIM / MS-SSIM for TensorFlow

由 人盡茶涼 提交于 2019-12-17 18:30:36
问题 Is there a SSIM or even MS-SSIM implementation for TensorFlow ? SSIM ( structural similarity index metric ) is a metric to measure image quality or similarity of images. It is inspired by human perception and according to a couple of papers, it is a much better loss-function compared to l1/l2. For example, see Loss Functions for Neural Networks for Image Processing. Up to now, I could not find an implementation in TensorFlow. And after trying to do it by myself by porting it from C++ or

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . Are there any tools available that will calculate code metrics (for example number of code lines, cyclomatic complexity, coupling, cohesion) for your project and over time produce a graph showing the trends? 回答1: On my latest project I used SourceMonitor. It's a nice free tool for code metrics analysis. Here is

Prometheus神器之监控K8s集群

由 北慕城南 提交于 2019-12-17 10:51:40
Prometheus 简介 Prometheus 是SoundCloud开源的一款开源软件。它的实现参考了Google内部的监控实现，与源自Google的Kubernetes结合起来非常合适。另外相比influxdb的方案，性能更加突出，而且还内置了报警功能。它针对大规模的集群环境设计了拉取式的数据采集方式，你只需要在你的应用里面实现一个 metrics 接口，然后把这个接口告诉 Prometheus 就可以完成数据采集了。 安装Prometheus 首先我们使用 ConfigMap 的形式来设置 Prometheus 的配置文件，如下 apiVersion: v1 kind: ConfigMap metadata: name: prometheus-configuration labels: app.kubernetes.io/name: prometheus app.kubernetes.io/part-of: ingress-nginx name: prometheus-configuration namespace: ingress-nginx data: prometheus.yml: |- global: scrape_interval: 10s scrape_configs: - job_name: 'ingress-nginx-endpoints'

Big-O for Eight Year Olds? [duplicate]

问题 This question already has answers here : What is a plain English explanation of “Big O” notation? (39 answers) Closed 2 years ago . I'm asking more about what this means to my code. I understand the concepts mathematically, I just have a hard time wrapping my head around what they mean conceptually. For example, if one were to perform an O(1) operation on a data structure, I understand that the number of operations it has to perform won't grow because there are more items. And an O(n)
