QUESTION
a simple summary is in the title but to further explain:
Whenever i open my terminal (iterm2) i load into zsh but completions don't seem to work, then when i manually run source .zshrc
it does fully load. I've tried moving stuff around in my .zshrc file to see if the order of loading was incorrect but it didn't fix anything.
My .zshrc file:
...ANSWER
Answered 2021-May-11 at 10:39You're making two mistakes in your .zshrc
file:
- If you do
source $ZSH/oh-my-zsh.sh
, then you shouldn't also doautoload -U compinit && compinit
, because the former includes the latter. plugins=( ... )
should be done before doingsource $ZSH/oh-my-zsh.sh
. The former does not do anything by itself.
So, change the top of your .zshrc
file to this:
QUESTION
The answer probably exists somewhere but I can't find it. I came to this question from an algorithm I am creating. Essentially a .contains(String s1, String s2)
that returns true if s1 contains s2, ignoring Greek/English character difference. For example the string 'nai, of course' contains the string 'ναι'. However, this is kindly irrelevant to my question.
The contains()
method of a String
uses the naive approach and I use the same for my algorithm. What contains()
essentially does, is to call the static
indexOf(char[] source, int sourceOffset, int sourceCount, char[] target, int targetOffset, int targetCount, int fromIndex)
which exists in java.lang.String.class
with the correct parameters.
While I was doing different kind of benchmarking and tests to my algorithm, I removed all the Greek - English logic to see how fast it behaves with only English strings. And it was slower. About 2 times slower than a s1.contains(s2)
that comes from JDK.
So, I took the time to copy and paste this indexOf
method to my class, and call it 15 million times in the same way JDK calls it for a string.
The class is the following:
...ANSWER
Answered 2021-Feb-17 at 16:37Because String.indexOf()
is an intrinsic method, making the JDK call a native implementation and your call a Java implementation.
The JVM doesn't actually execute the Java code you see, it knows that it can replace it with a far more efficient version. When you copy the code it goes through regular JIT compilation, making it less efficient. Just one of the dozens of tricks the JVM does to make things more performant, without the developer often even realizing.

I honestly don't remember what I last installed on my machine, I believe it was brewing gatsby-cli. Anyway, since yesterday morning my terminal has been giving me the following error when I open a new instance or reset the terminal (open a new tab, source ~/.zshrc, etc).

QUESTION
As far as I understand, when I do 'foo' in 'abcfoo'
in Python, the interpreter tries to invoke 'abcfoo'.__contains_('foo')
under the hood.
This is a string matching (aka searching) operation that accepts multiple algorithms, e.g.:
How do I know which algorithm a given implementation may be using? (e.g. Python 3.8 with CPython). I'm unable to this information looking at e.g. the source code for CPython for string. I'm not familiar with its code base, and e.g. I can't find the __contains__
defined for it.

How would I go about implementing Boyer-Moore Search for streams? I understand how to implement this for a given string where we know the length of the entire string. However, what if we have no idea the size of the string (i.e it's an arbitrary length stream of bytes).
I'm trying to implement this in PHP so any code in PHP would be helpful.
Here's the implementation of Boyer-Moore Search I have in PHP:
...ANSWER
Answered 2020-Apr-06 at 09:42Note that you only ever use the $needleLen
most recent characters from the stream. So you can maintain a sliding window consisting of $needleLen
characters and advance it as needed. Furthermore, $haystackLen
is now unknown and should be replaced with EOF checks.
The code below is inefficient because sliding the window always takes O(n)
regardless if we slide it by n
characters or just 1. To achieve optimal sliding complexity, the $window
should be implemented as a circular character buffer.

I created a database Form with 2 comboboxes, Combo1
and Combo2
.
Combo2
visibility depends on Combo1
status: Combo1
checked, Combo2
visible; Combo1
unchecked, Combo2
hidden.
I expected to find something like Combo2.setVisible(Combo1.isVisible())
but I have been too optimist.
This is the macro I have been playing with:

QUESTION
Someone texted me this character: ◡̈
They were using it as a smiley emoji, and depending where it's rendered, it looks either like two dots over a curve or two dots to the right of a curve.
When I saw it, I wondered if it came from some other language, so I opened wiki's list of unicode characters and searched it. There are zero matches. Yet I know it must be there somehow since I'm able to use it.
Now here's the next thing: when I pasted the character into the searchbox in chrome to string-search the wiki page, it's a single character. But when I hit backspace, it only removes the dots, leaving the semi-circle which immediately matches U+25E1
, "lower half circle."
So what is this? An umlaut over a lower half circle character? How does that work? Can you add accent marks on any arbitrary unicode character? If so, how? And how does that work with encoding?
...ANSWER
Answered 2020-Jan-25 at 05:44What's copied from the title (◡̈) is encoded in UTF-8 as two characters with codes U+25E1 (0xE2 0x97 0xA1) and U+0308 (0xCC 0x88).
The 'combining diaeresis' combines with another character. It's not obvious why the characters are rendered differently in different places. The Unicode standard says Chapter 2: General Structure p21:
Combining characters (such as accents) are stored following the base character to which they apply, but are positioned relative to that base character and thus do not follow a simple linear progression in the final rendered text.
You can find plenty of evidence for 'zalgo' on SO — they are mighty piles of combining characters:

QUESTION
Suppose I have a very long string, such as a filepath, and I want to search for something in it. For example, something like the $ find
command. It seems like a basic implementation of this would be along the lines of:
ANSWER
Answered 2019-Aug-27 at 21:42Advanced search algorithms like Boyer-Moore and Aho-Corasick work by precomputing lookup tables from the string(s) to be searched for, which incurs a large start-up time. It's very unlikely that searching something as small as a pathname would be able to make up for that high overhead. You really have to be searching something like multi-page documents before those algorithms show their value.
