I am finding a lot of posts on this forum that have to do with finding various values in a text file and outputting text surrounding it. However, I don't seem to find any "stream oriented". I want to find a particular string in a file, and output only the text that follows it until the end of t...

I've created a simulator for the Premier League, which takes in all of the 20 teams and plays them against each other, recording the results and outputting a table at the end. The skill levels are based off a prediction in an article by The Telegraph. I am wondering whether or not my code can b...

I'm considering to get a light meter Sekonic LX 308 without Spot meter. I'm wondering if I will miss something important without having spot meter. Is it worth it to get a light meter with spot meter on it? e.g. Sekonic L858.

I've been using LaTeX for years and never saw this before: if an item (in enumerate) starts with an \hbox, then the \hbox is placed before the label! \documentclass[12pt]{article} \def\Blank#1{\relax{\hbox to 1in{\hrulefill\textsl{#1}\hrulefill}}} \begin{document} \section{Example} Here's a ...

One manager recently left the company and I received the urgent request to deactive his username. Because the manager was part of several approval processes , for me it is taking longer than expected. is any other way to quickly resolve this issue like change of email address or profile or record...

We're trying to create a nested package structure to keep our code organized. So far, we have a design that looks like this: core ^-- utils | ^---- marketing | ^---- support | ^---- ...etc... ^-- integrations We've created the "core" and "utils" package, but when trying t...

This might be a pretty dumb question, but I couldn't find a straightforward answer on the forums. If I build a custom WP theme using the two Lyra guides at https://www.lyrathemes.com/bootstrap-wordpress-theme-tutorial-1/ and https://www.lyrathemes.com/bootstrap-wordpress-theme-tutorial-2/) ...

Say, I have written a code which performs a physics calculation. After this, I get a paper published based on the results of the code. In interest of advancing the progress of science, I upload the code of the paperon say Github. I also post a link to my code on github on my website. This to faci...

I have a team summit which unfortunately falls on Rosh Hashanah and I will not be able to attend. It is not mission critical that I be there - it is more for team building but still the team spent a lot of time organizing it. It is at a very nice hotel and everyone is expected to be there. My m...

Fantastic universe, but not necessarily magic involved in the process. You face a guy who has a shield (tower shield of not). You don't have a shield, but you're a better sword. How do you win? According to Dark souls, your best option is kick the shield, but realistically speaking it's hard to ...

I have a dataset with column and row keys: dsA={<|"keyA" -> <|"key1" -> "a", "key2" -> "b"|>, "keyB" -> <|"key1" -> "c", "key2" -> "d"|>|>, <|"keyC" -> <|"key1" -> "a", "key2" -> "b"|>, "keyB" -> <|"key1" -> "d", "key2" -> "f"|>|>}//Dataset Because the row keys get in the way of a...

Martin Hofmann states in Extensional Concepts in Intensional Type Theory (§1.1 p.3) that: It is important that definition equality is pervasive so if M and N are definitionally equal then P(M) is definitionally equal to P(N) whatever P is. In particular the proposition stating that M is propo...

Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes. Chromosome 1 spans about 249 million nucleotide base pairs, which are the basic units of information for DNA. It repre...

In an earlier challenge I asked code golfers to produce strings which copy each character in a string. For example: TThhiiss iiss ddoouubbllee ssppeeaakk!! This challenge is simply to detect if some text meets the definition of a double speak string. There is an even number of characters....

I'm converting unscoped enumerations to scoped enumerations, and have run across a puzzle. Stroustroup, C++ Programming Language, 4th edition, Section 8.4.1, documents that scoped enum classes are not implicitly converted to integral types, and provides code for operators | and & as an example o...

I'm going to be taking a trip to Germany in a few days. I will be in Munich and I was considering taking the train to somewhere in Austria (Innsbruck maybe?) so I could see the Alps. I'm wondering how difficult it is to travel between countries for something like this? Do I need to go throug...

I bought a new computer, a precision tower 7920 with Quadro RTX 4000 GPUs. Because the nvidia driver installation is so complicated, I ordered the machine with Ubuntu (as it was supported by DELL and comes pre-installed). However from the very first time I turned the computer on it won't boot, g...

The Singh family lives in a housing development full of Scientists and engineers (god forbid!). The Home Owners have come up with weird ways of numbering their houses. K Street is all engineers and M street is all mathematicians. Turns out Mr. Singh is an engineer and of course Mrs. (D...
