2022.01.28 19:13 shikalaka Error when trying to plot Fourier series
I have to plot a fourier series but i dont know how to sum functions, here is what i wrote
The resulting error is
import numpy as np from matplotlib import pyplot as plt def g(t): k=np.zeros(5000) i=0 k=1 while i<=4999: k[i]=2*i+1 i+=1 ck = 2/(np.pi*k) omegak=2*np.pi*k return np.sum((2/(k*np.pi))*np.sin(2*k*np.pi*t)) t=np.linspace(-2,2,5000) plt.figure(figsize=(10,5)) plt.plot(t, g(t)) plt.xlabel('t[T]') plt.ylabel('g(x)') plt.grid(ls='dashed') plt.show()
but i dont know how to solve it and why it does that.

2022.01.28 19:13 Ben5544477 Is it possible that a company would try to motivate employees to work hard by having attractive people around them? Or would companies not do that?
I worked somewhere where there was a very attractive person. I would guess over 90% of men or more would find her very attractive. She would always just walk around the office and ask people how they're doing or say small things to them.
I always wondered if the real reason why she's doing that is to try to motivate the employees to work hard.
Could I be right about that assumption or am I most likely wrong?

2022.01.28 19:13 arcspin Roles Structure & Naming Convention
I am looking at spending time to improve our roles structure and was considering naming the roles right after the positions (i.e. Emp Accounting Analyst). this would eleviate a lot of the guess work we have with our messy environment now on what role has what permission etc...
am i missing anything in this logic that might cause issues?

2022.01.28 19:13 i_am_adult_now Myths and Misconceptions in C
I come across videos, blogs, text books and Reddit posts on C language that are often wrong or deeply rooted in myths and misconceptions. This little post is an attempt at clarifying a few things so there's no more misunderstandings about primitive data types. Before I go any further, remember this one little thing:
The JTC1/SC22/WG14 peoples try everything in their power to not make assumptions about the underlying hardware or the system environment.It is one of the core tenets of C programming language. See,
longare not of fixed sizes and their size are not the same across compilers. If you dig into ISO C-89/ANSI standard, you'll notice they're all relative to each other and that
charis derived on the definition of a Byte. In, ISO C-89 sec 1.6, byte itself is defined as:
the unit of data storage in the execution environment large enough to hold any member of the basic character set of the execution environment. It shall be possible to express the address of each individual byte of an object uniquely. A byte is composed of a contiguous sequence of bits, the number of which is implementation-defined. The least significant bit is called the low-order bit; the most significant bit is called the high-order bit.As for the "basic character set", ISO C-89 sec 2.2.1 lists about 100 characters that in total needs at least 7 bits to represent. And if you scroll down a bit into numerical limits, the predefined macros,
SCHAR_MAXmust be at least be -127 and +127 respectively. So 7 bits for integer and 1 bit for sign, you get 8 bits -- the minimum required value for predefined macro
CHAR_BIT. Now, most popular CPUs like Intel, ARM, MIPS, SPARC all have 8 bit bytes which is where the misconception that all bytes are exactly 8 bits comes from. That same numerical limits section enforces the relativity rule that
intmust be at least 16 bits and
longmust at least be 32 bits. See? It's always "at least" and "minimum", not "exact".
sizeofoperator returns the size of its argument in bytes. So if
CHAR_BITwere 16, then
sizeof(uint16_t)will be 1 because a 16 bit integer fits into a single byte.
CHAR_BITis greater than 8? Of course, yes! Off the top of my mind, Texas Instruments TMS320C28x in section J.3.4 says, "The number of bits in a byte (CHAR_BIT) is 16". SHARC's CrossCore Embedded Studio allows you to specify the size of
charvia CLI argument
CHAR_BIT. You can even mix and match to your liking!
-std=c99 -Wpedantic -Werroron CLI. That way, you can include
stdint.hand use size guaranteed data types like
uintand don't have to think too much. But still, I urge you to know your hardware well.
charis always 8 bits. There are plenty of these buffoons around who take a 30-minute online course on introduction to programming and think they know computer science. They write blogs, make tutorial videos, and some even go on to write books. I don't want to name names but you know who they are. Please spend some time reading the standards to appreciate why C is the way it is. It will certainly go a long way.
