Otherwise you'll have to regularly explain the past/alternative names, and deal with persistent confusion. (e.g., Page-triage/Page-curation/Newpagepatrol/Newpagesfeed, or Echo/Notifications, or Popups/Hovercards/PagePreviews). Renaming things is even harder: the first name used in public is likely to stick, even if you think it's terrible Instance key naming. The instance key needs to be manually appended to the snap name, and takes the following format: <snap>_<instance-key> For example, the following are valid instance names, for example: hello-world; hello-world_foo; hello-world_0123456789; Only lowercase letters or digits are valid, and the instance name can be up to 10 characters long. After being set during the installation of a snap, an instance name cannot be changed
Long a favorite saying of mine, one for which I couldn't find a satisfactory URL. Like many good phrase, it's had a host of riffs on it. A couple of them I feel are worth adding to the page. There are 2 hard problems in computer science: cache invalidation, naming things, and off-by-1 errors. -- Leon Bambrick For names that are only in the xkcd name space there is no reason to include the extra 5 characters. minimum number of variables. The other concern is that we can not encode the single letter colors as hex due to float rounding issues where as the CSS4 colors are defined as RGB hex values. On Mon, May 9, 2016 at 4:37 PM Antony Lee firstname.lastname@example.org wrote: Then base could cover. . camelCase.

His Color Name Survey (with 200 000 participants) resulted in a list of nearly 1000 color names. The color names cannot be used in HTML. These hex values are non official approximate values intended to simulate the colors in HTML Now let's have a look at variables and their naming conventions. With variables it is easier to have non-descriptive names, but you should still know what to expect. For example, let's have the variable name user. What is it? It could be. User Object; User ID; User email; Of course, it should be the user object. Changing the variable to say userObject is one way of dealing with it, which I highly recommend. However, this is not the only solution

Nice try, kids. Nobody can spell fuchsia. Overall, the results were really cool and a lot of fun to analyze. There are some basic limitations of this survey, which are discussed toward the bottom of this post. But the sheer amount of data here is cool. Sex. By a strange coincidence, the same night I first. Variables Descriptive names that differ significantly Smallest practicable scope for variables; initialize at point of definition Use typedefs to define narrow types (also use uint32_t, use enum , etc.) Range checks & bounds checks (e.g., buffer overflow) Handle errors returned by called functions. Good Code Hygien First, let's get a few things out of the way: In real life, we can't put a metal pole between the Earth and the Moon.For one, someone at NASA would probably yell at us. The end of the pole near the Moon would be pulled toward the Moon by the Moon's gravity, and the rest of it would be pulled back. Good variable names eliminate the problem of distance because they remind the reviewer of their purpose. That way they don't have to scan back to an earlier part of the code. The other tax is boilerplate. Code is often doing something complicated; it was written by someone else; reviewers are often context-switching from their own code; they review a lot of code, every day, and may have been.
That said I see it is often missused by naming functions with first letter lower case, which according to Microsoft is for function parameter variable names. Though while it doesn't matter, I have gotten flack for it on this site and others. Again personally I find Microsoft code to be most visually appealing, if I dare say I find any code to be visually appealing really.

Vous avez maintenant toutes les combinaisons correctes, mais vous en vÃ©rifiez encore plus que nÃ©cessaire (comme en tÃ©moignent les nombreuses permutations de votre rÃ©sultat) The xkcd colors come from a user survey conducted by the webcomic xkcd. 95 out of the 148 X11/CSS4 color names also appear in the xkcd color survey. Almost all of them map to different color values in the X11/CSS4 and in the xkcd palette. Only 'black', 'white' and 'cyan' are identical. For example, 'blue' maps to '#0000FF' whereas 'xkcd:blue' maps to '#0343DF'. Due to these name collisions.

We recently programmed Bucket, the IRC chat bot in #xkcd, to allow people set their gender so he can use pronouns for them. This ended up taking hundreds of lines of code, three pages of documentation, and six different sets of pronouns and variables, just to cover all the basic ways people in the channel with different gender identifications wanted to be referred to (even without invented. Naming functions should respect the best practices already covered in the Naming variables, however, there are a few other points worth raising that are exclusive to function and method names. Firstly, your user should be able to infer the purpose or action of a function from its name. If you can't describe the overall task performed by the function in a few words, then it may be that your. A very common mistake that beginning programmers make is to be sloppy in writing variable names, sometimes using capitals and sometimes not. It is not good programming practice to use two variable names that are spelled the same except for capitalization because it leads to errors. Your source code will be easier for mere mortals to understand (interpret this to mean the instructor grading.
This is going to cause problems for the colour naming test - if the previous colour alters the perception of the next, then that's obviously going to have implications for the naming of that colour. I assume that the results are going to be considered regardless of order, meaning that another variable will interfere with the results In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data.In the broadest sense correlation is any statistical association, though it commonly refers to the degree to which a pair of variables are linearly related. Familiar examples of dependent phenomena include the correlation between the height of parents. Global variables are visible everywhere: Use of globals indicates poor modularity - Globals are prone to tricky bugs and race conditions Local static variables are best if you need persistence - File static variables can be OK if used properly - Don't make procedures globally visible if not needed Global Variables Are Evil One of the issues of why OO is preceived difficult and complex in enterprise-quality SAP ABAP contexts is that most companies force you to follow naming conventions for variables, classes and methods (I should know, I'm the caretaker of this stuff at my company). Prefixing a class with a 7-letter naming convention string (based on functional area, project, stream and god knows what) does. 7 Multivariate Analysis. Many datasets consist of several variables measured on the same set of subjects: patients, samples, or organisms. For instance, we may have biometric characteristics such as height, weight, age as well as clinical variables such as blood pressure, blood sugar, heart rate, and genetic data for, say, a thousand patients
As it turns out, naming servers is hard. Why? Deploying them has become incredibly easy. With automation & virtualization, servers can be deployed in seconds. SysAdmins that were once responsible for ten servers can now be in charge of hundreds, if not thousands. You just can't think up that 429,736 (good) names! Many people only get to name a dog, their children (maybe?), and possibly a. First of all, you have multiple PEP8 code style violations, like using camel case styled variable naming instead of a lower case with underscores; organizing, grouping imports, comments not formatted properly.. I would also apply the following improvements: use requests.Session() to re-use a single web-scraping session to make requests - this should have a positive impact on performanc > Red, green or blue is good enough for me. :-) Ah, but there is power in naming things. The original author converted all spaces, slashes, and apostrophes to underscores, resulting in some name duplications and redeclared variables. Instead, the attached file changed slash characters to _SLASH_, apostrophes to _APOS_, and only spaces to. In statistics, a contingency table (also known as a cross tabulation or crosstab) is a type of table in a matrix format that displays the (multivariate) frequency distribution of the variables. They are heavily used in survey research, business intelligence, engineering, and scientific research. They provide a basic picture of the interrelation between two variables and can help find.
Some aspects are showing their age (naming conventions, API s) Emacs is single-threaded, meaning It's used as my doom-variable-pitch-font and in the graph generated by Roam.

For scientists (and hopefully for rigorous data scientists), an experiment is an empirical procedure to determine if an outcome agrees or conflicts with some hypothesis. In a machine learning experiment, your hypothesis could be that a specific algorithm (say gradient boosted trees) is better than.
Usually when we embark upon a data crawling or analysis project, it's because one of our customers is interested in collecting data from the web. Sometimes, it's because we have a question that we'd like to see answered. In this case, we were curious which XKCD comics are the most popular of all time. We thought we'd use this as a simple primer for how you can use the Priceonomics. Beyond the Mouse - A Short Course on Programming 2.

Variable names that consist of a single character may be uppercase. In general, even single-character variable names should be lowercase. However, in some situations, mathematical notation uses uppercase letters. In such situations, uppercase variable names may be used. For example, matrices are often written using uppercase letters. So, an expression like (b = A*x) would be appropriate. In your first code sample, the problem is that parameters in queries cannot be schema names.SQLite needs all of the names up front to prepare the query for efficient execution. The query planner cannot know what to do with a statement if you don't provide the elements of the schema it will operate over, so if SQLite allowed this, it would have to re-prepare the query each time it ran Any readers will know that the bulk of xkcd comics are simple black-and-white images with stick figures and you can see this reflected in the almost Â¾ to Â¼ ratio of monochrome to coloured images. 3 Comments to The only valid measurement of code quality - WTFs / Minute July 16, 2011 at 5:35 am . 515 votes, 169 comments.

Show Code # Import Data df = pd.read. 16 Naming Conventions Choosing good identifier names is important for any program, but it's especially important for large projects. Good naming conventions may differ in detail, but what they have in common is that they propose a consistent scheme that can be applied throughout a project to make the code easier to understand. You may not get to choose which conventions to apply When it comes to variables, it is essential to distinguish between categorical variables (names or labels) and quantitative variables (numerical values with magnitude) to ensure we plot the correct type of plot for that variable. For example, in crime data, 'type of offence' (criminal damage, common assault, etc) would be a categorical variable, whereas in health data, the 'resting heart. Boolean variables and value-returning routines should have adjective-like names: valid, failedMidterm, containsAZero. The name describes how the world/argument is when this thing is true .

Python Naming Convention. The style guide for Python is based on Guido's naming convention recommendations. List of covered sections: Class Naming; Constant Naming; Method Naming; Module Naming; Variable Naming; Package Naming; Exception Naming; Underscore; TL;D Note that the memory location is the *starting location* of the variable's data. A memory location names a particular byte of memory; a `double`, for example, has 8 bytes so the memory location would just say where the first byte is stored (the other 7 bytes can be obtained by adding 1, 2, 3, etc. to the memory location). ## Pointers > A memory reference instruction which is to use an indirect. As a general rule, don't use spaces, either in variable names or le names. They make programming harder: the analyst will need to surround everything in double quotes, like glucose 6 weeks, rather than just writing glucose 6 weeks. Where you might use spaces, use underscores or perhaps hyphens. But don't use a mixture of underscores and 4 $&&(37('0$186&5,37 $&&(37('0$186&5,37. Table 1. For instance in Python, metasyntactic variables takes the names of spam and egg, rather than the more traditionally used foo and bar. This is a clear reference to the Monty Python sketch Spam .

fixed some wrong variable names which don't seem to be doing much anyway; I'll test those some other time and maybe remove them if they aren't needed; Supposedly they make sure boost descriptions update after you click a button on them; Fixed mustard where 0s after decimal points went missing. i.e 1.01 was displayed as 1.1 when showing 2. Using good variable names should be obvious. Note that in the examples provided so far, I named my variables in such a way that they told me what they represent physically.

These hex values are non official approximate values intended to simulate the colors in HTML Bubble Charts. Bubble Charts are used to display three dimensions of data on a two dimensional.
If you now think 26 variable names should be enough: Some of the letters, like X and Y, had special predefined meaning and you couldn't change that. If you used seem you encountered strange behaviour, like values changing behind your back. To add insult to injury I could never find documentation about which variables were special, so I stuck with the few I new were safe, which were not many.
