海外TECH	DEV Community	The importance of good Documentation	https://dev.to/wraldpyk/the-importance-of-good-documentation-19og	The importance of good DocumentationWe all know documentation is an important part of any software Whether that is through self documenting code or hosted documentation on dedicated websites In the end all that matters is the quality of the documentation I ve been in software development for most of my life and so consuming documentation tutorials guides or otherwise has been part of most of my life because of that Over the years I ve dealt with everything from completely missing documentation to the most complete and comprehensive documentation imaginable And of course everything in between The most common form of documentation however is within the files I m dealing with In the end as a software developer most software I m dealing with has been written by the team I m involved in and usually no disconnected documentation is written In the end this typically means two things Software without comments or software with comments In the past I ve written about self documenting code and its importance And I still stand by this fact When dealing with software development teams there s no way there s time for maintaining proper documentation Practicing the routine of having well named functions variables and filenames is easier than having to explain in your code what everything does And this brings me to the opinion that documentation has to be either good or non existent If you have a different view on this I d love to discuss this with you It s always interesting to hear different approaches and I d love to be proven wrong Whenever you or anyone in your team decides to write external documentation you or your team will have to continuously put in the effort to maintain this documentation Make it part of the routine to update whenever relevant products or tools get updated and whenever you estimate anything related to these tools also estimate the time it takes to update the documentation accordingly And here s why As soon as the documentation is slightly outdated or incomplete those reading the documentation can assume two things Either the documentation is outdated and they ll have to figure things out for themselves or they ve discovered a feature that might or might not be not intended to be used When you encounter undocumented features you ll need to ask yourself if you want to use this feature There can be consequences of using them and I think most people in software development have had to deal with this Often undocumented features can be broken in future versions Either intentional or unintentional There s a big chance they re undocumented for a reason They might be pending deletion once the final piece of software using it is rewritten or they might not be feature complete yet and have breaking changes in the near future In any case once you find undocumented features you need to do your own research When it s software written by the same team you can simply ask the person who wrote it Thanks git blame and get your answers But if the software is from a rd party you can either never know the answer or you ll have to raise a ticket and hope for a proper and timely response And this is exactly why documentation needs to be up to date or non existent in the first place If there was no documentation at all and the software was simply self documenting you wouldn t have to worry about any of this But if any documentation contradicts the actual software you can get down to endlessly researching what part is the supposed truth Is it a bug Is it an undocumented feature Is it an accidental commit that slipped through code review Or is it simply a forgotten piece of software that should ve been documented in the first place but there was no attention given to it All I m trying to say is to make sure you consider what you document and schedule time for maintenance every time the software is changed And this doesn t just apply to your or your team s codebase but also to SaaS and other software where the user doesn t touch any code at all If you document something document it well or omit it completely Humans are remarkably capable of figuring out things for themselves but if they re told to do things according to specification and it doesn t work as expected you raise questions In the past years I ve worked as a Developer Advocate for several companies and if there s one thing I ve learned over the years is that most questions come from incomplete or outdated documentation The number of questions I ve had cross my desk about documentation that was forgotten about and completely outdated non functional by the time the user in question started using it is insane But whenever software was released undocumented the questions were mostly due to bugs in the software not because of the lack of documentation and those questions will be there regardless of documentation or not And trust me this was not due to lack of adoption ConclusionSo in conclusion Well I ve already said this a few times but it can t be repeated often enough There are in my opinion only two routes you can take Omit documentationOmit documentation en and make everything either self documented in case of SDK s code files or intuitive in case of SaaS In both situations here developer user experience should be on top of your mind Always update documentation accordinglyWrite proper documentation and always keep it up to date Schedule time every time the SDK product gets changed to make sure the documentation is up to date and simply never let this slide As soon as you forget to update your documentation once it s easy to do it more frequently and before you know it your documentation is a dinosaur and doesn t help your users at all It hurts adoption productivity and maybe even your company	2022-05-28 10:34:23
海外TECH	DEV Community	Questions whose answers are worth knowing in Machine Learning for beginners!	https://dev.to/seek4samurai/questions-whose-answers-are-worth-knowing-in-machine-learning-for-beginners-3a1d	Questions whose answers are worth knowing in Machine Learning for beginners Some concepts and answers one should know in machine learning before going further Wrote them in my weekend because I was bored and I thought to dive into some data science machine learning and statistics Explain what is regression Regression is a supervised learning technique which helps us in finding the correlation between the dependent target variable and one or more independent predicting variable s It is mainly used for predictions weather forecasting or determining the causal effect relationship between variables In Regression we plot a graph between the variables which best fits in the given data points or dataset using this plot the machine learning model can make predictions about the data Fact The method in which we analyse such type of regression is called Regression Analysis which is indeed a statistical analysis to model the relationship between a dependent target and independent predictor variables with one or more independent variables What is Geometric machine learning model Before we get to know the actual meaning of Geometric machine learning model we need to know what s Euclidean data and non Euclidean data So basically most of the data and information that we get to know or have is Euclidean data most of it Euclidean data is just the datatypes that exists in dimension or dimension domain Euclidean data consist of audio images videos numbers some text and more similar type of data A non Euclidean data is much like that we can t really explain in simple ways and it require much like dimensional explanation for example a molecular structure or some hierarchy or a tree structure Here a molecular structure or a network structure is a D structure which will fall into non Euclidean data After all above Geometric machine learning model or Geometric Deep learning GDL is the model that aims to deal with or learn from the non Euclidean data or Geometric machine learning model or Geometric Deep Learning GDL is the niche field under the umbrella of deep learning that aims to build neural networks that can learn from non euclidean data What is Analysis of variance ANOVA Analysis of Variance is a test which an analyst might perform to check the difference among the means of the population by examining the amount of variation within each of the sample ANOVA is the statistical approach of testing or comparing the two datasets this is one of the best applied test when we have more that populations or samples to be compared But to compare the means of two or more populations or datasets ANOVA would be appreciated if the samples of datasets satisfies the following Independence of case gt this assumption means that the case or samples of dependent variable should be independent or selected randomly there should not be any sequence or pattern to be followed when selecting sample datasets Normality gt this means that the distribution of each group should be normal Homogeneity gt this means that the variance between each group should be same What are the types of Analysis of variance ANOVA ANOVA has basically types One way analysis when we are comparing or more than groups based on factor variable then it s said to be one way analysis of that group Example if we want to compare whether or not the mean output of three employees is same or not based on the working hours of the three employees Two way analysis when there are two or more factor variables in a comparison then it is said to be two way analysis of those groups Example if we compare whether or not the mean output of three employees is same or not based on their working hours and working locations K way analysis When factor variables are k then it is said to be the k way analysis of variance ANOVA Explain in brief what is T test and Z testBefore we dive in both of these tests we need to know what is Hypothesis testing A more descriptive article about this can be found here So hypothesis testing is method for us to test if our hypothesis is true or false about the population using the sample dataset Through hypothesis testing we can know if we have enough evidence about the population and conclude if our hypothesis is true or false So what is Z test and T test Well both are Parametric tests i e they rely on statistical distribution of the dataset To know more about Parametric tests check this out Z Test Z test is a hypothesis test which ascertains the averages of the two datasets are different from each other when standard deviation or variance is given Z test is usually preferred over T test when in a dataset sample size gt It is based on Normal distribution and all data points are independent T test T test is also a hypothesis test which is used when either the standard deviation or variance is not known or the sample size lt in a dataset This states how averages of two datasets differ from each other This test is based on t distribution and data points are not dependent Hope this was informative for you I might post few more briefly explained questions on similar topics Thanks for reading	2022-05-28 10:17:58
