• Named Booleans prevent C++ bugs and save you time

  During a recent code review I found a hard to spot bug, a misplaced parenthesis in an `if` statement. I often employ a technique I call `named booleans`, which would have prevented this bug. It's a simple technique, instead of a long `if` statement, give every comparison a seperate boolean variable with a descriptive name and use those variables is the `if` statement. This post shows the bug in question, an example of my `named booleans` technique and another tip regarding naming magic numbers.

• Python Check If String Contains Substring From List

  To check if the string contains substring from the Python list, the “list comprehension”, the “any()” method, and the iterative function “for” loop is used.

• Divide Two Columns Pandas

  To divide two columns Pandas in the Python, the “/” divide operator, “div()” methods, and “np.where()” methods can be used.

• Convert 1d Array to 2d Array Python

  To convert a one-dimensional array into a two-dimensional array, the “reshape()” method, “np.reshape()” method and “np.arange()” method can be used.

• Remove Number From String Python

  To remove the number from the string in Python, the “join()” and “isdigit()” methods, “translate()”, “filter()”, and “sub()” methods are used.

• How Do You Repeat a String n Times in Python?

  To repeat a string “n” times in Python, the repetition “*” operator, “for” loop an iterative function, and user-defined function can be used.

• How to Initialize a Dictionary in Python

  To initialize the dictionary, “fromkey()”, “defaultdict()”, “setdefault()”, “dict()”, “zip()”, passing arguments, and curley “{}” braces techniques are used.

• Datetime Get Previous Month Python

  To get previous month's datetime in Python, the “datetime” module with “replace()” method and “datetime” module using the extension “dd” techniques can be used.

• Initialize 2D List in Python

  To initialize the 2d list in Python, the “range()” method and “numpy.full()” method with the “tolist()” method are used.

• Remove Quotes From String Python

  To remove the quotes from any Python string, the “for” Loop, the “replace()”, “re.sub()”, “strip()”, “Istrip()” and “rstrip()” methods are used.

• Why I'm not the biggest fan of Single Page Applications - Manuel Matuzović

  Sometimes it seems like accessibility experts and other web professionals hate JavaScript. This might be true for some, but most understand that JavaScript can be useful for improving UX and even accessibility. JavaScript solutions are often more accessible than their pure HTML or CSS counterparts.

• Jussi Pakkanen: PDF output in images

  Generating PDF files is mostly (but not entirely) a serialization problem where you keep repeating the following loop:

  • Find out what functionality PDF has
  • Read the specification to find out how it is expressed using PDF document syntax
  • Come up with some sort of an API to express same
  • Serialize the latter into the former
  • Debug

  This means that you have to spend a fair bit of time without much to show for it apart from documents with various black boxes in them. However once you have enough foundational code, then suddenly you can generate all sorts of fun images. Let's look at some now.
