a |= b; is the same as a = (a | b); It calculates the bitwise OR of the two operands, and assigns the result to the left operand.

As far as I am concerned, keeping a linear history is mostly for asthetics . It's a very good way for a very skilled, disciplined developer to tidy up the history and make it nice to skim through. In a perfect world, we should have a perfectly linear history that makes everything crystal clear. However, on a large team...

You don't "need" it. But defining it allows your object to be implicitly converted to string, which is convenient. Having member functions that echo directly is considered poor form because it gives too much control of the output to the class itself. You want to return strings from member functions, and let the caller ...

With Wolfram Alpha, you get what you pay for. If $f(x)=|e^x+(1+i)e^{-x}|$ then$$F(x)=f(x)^2=(e^x+e^{-x})^2+e^{-2x}=e^{2x}+2+2e^{-2x}.$$Then $F'(x)=2f(x)f'(x)$ and so$$f'(x)=\frac{F'(x)}{2f(x)}=\frac{e^{2x}-2e^{-2x}}{f(x)}.$$

Question: How did mathematicians prior to the coming of calculus derive the area of the circle from scratch, without the use of calculus? The area, $A$, of a circle is $\pi r^2$. ...
There's an interesting method using which you can approximately find the area. Split up the circle into many small sectors, and arrange them as a parallelogram as shown in the image (from wikipedia) The higher the number of sectors you take, the more it tends to a parallelogram, with one of it’s height the radius $r$ ,...

There's no append function. It's not hard to write one though: function appendToStorage(name, data){ var old = localStorage.getItem(name); if(old === null) old = ""; localStorage.setItem(name, old + data);}appendToStorage('oldData', $i("textbox").value); Note: It makes more sense to define a function append on...

The trailing , in the print statement will surpress a line feed. Your first print statement doesn't have one, your second one does. The input you read still contains the \n which causes the extra linefeed. One way to compensate for it is to prevent print from issuing a linefeed of its own by using the trailing comma. A...

I was able to figure out this myself. After digging trough the Android source code I found that the scaledDensity property is calculated as scaledDensity = density * fontScale where fontScale depends on the system setting for font size. So this was just as I thought it should be. The reason why scaledDensity always had...

Short Answer If you already have an index column (suppose it was called 'id' ) you can filter using pyspark.sql.Column.between : from pyspark.sql.functions import coldf.where(col("id").between(5, 10)) If you don't already have an index column, you can add one yourself and then use the code above. You should have some o...

If you take the time as 6:30 PM as user input then you can use strtotime() to convert it to a timestamp, which you can then format for storage in the database. Use the MySQL TIME data type which requires the time format in HH:MM:SS (24 hour). Example: $dbFormat = date('H:i:s', strtotime('6:30 PM')); Produces: 18:30:00 ...

I'll try to answer in the simplest way.

If you understand how an astable multivibrator works, you can get to see how this one works, except that instead of going back and forth it actually goes "in a circle".
