QUESTION
Given a list of Strings:
...ANSWER
Answered 2022-Mar-22 at 07:13This problem should be solved easily using a trie.
The trie node should basically keep a track of 2 things:
- Child nodes
- Count of prefixes ending at current node
Insert all strings in the trie, which will be done in O(string length * number of strings). After that, simply traversing the trie, you can hash the prefixes based on the count as per your use case. For suffixes, you can use the same approach, just start traversing the strings in reverse order.
Edit:
On second thought, trie might be the most efficient way, but a simple hashmap implementation should also work here. Here's an example to generate all prefixes with count > 1.
QUESTION
The installation on the m1 chip for the following packages: Numpy 1.21.1, pandas 1.3.0, torch 1.9.0 and a few other ones works fine for me. They also seem to work properly while testing them. However when I try to install scipy or scikit-learn via pip this error appears:
ERROR: Failed building wheel for numpy
Failed to build numpy
ERROR: Could not build wheels for numpy which use PEP 517 and cannot be installed directly
Why should Numpy be build again when I have the latest version from pip already installed?
Every previous installation was done using python3.9 -m pip install ... on Mac OS 11.3.1 with the apple m1 chip.

I have an iOS app, since upgrading to Xcode 13, I have noticed some peculiar changes to Tab and Navigation bars. In Xcode 13, there's now this black area on the tab and nav bars and on launching the app, the tab bar is now black as well as the navigation bar. Weird enough, if the view has a scroll or tableview, if I scroll up, the bottom tab bar regains its white color and if I scroll down, the navigation bar regains its white color.

QUESTION
I have some pretty complicated objects. They contain member variables of other objects. I understand the beauty of copy constructors cascading such that the default copy constructor can often work. But, the situation that may most often break the default copy constructor (the object contains some member variables which are pointers to its other member variables) still applies to a lot of what I've built. Here's an example of one of my objects, its constructor, and the copy constructor I've written:
...ANSWER
Answered 2022-Jan-30 at 02:54C++ Copy Constructors: must I spell out all member variables in the initializer list?
Yes, if you write a user defined copy constructor, then you must write an initialiser for every sub object - unless you wish to default initialise them, in which case you don't need any initialiser - or if you can use a default member initialiser.
the object contains some member variables which are pointers to its other member variables)
This is a design that should be avoided when possible. Not only does this force you to define custom copy and move assignment operators and constructors, but it is often unnecessarily inefficient.
But, in case that is necessary for some reason - or custom special member functions are needed for any other reason - you can achieve clean code by combining the normally copying parts into a separate dummy class. That way the the user defined constructor has only one sub object to initialise.

QUESTION
I know Python // rounds towards negative infinity and in C++ / is truncating, rounding towards 0.
And here's what I know so far:
...ANSWER
Answered 2022-Jan-18 at 21:46Although I can't provide a formal definition of why/how the rounding modes were chosen as they were, the citation about compatibility with the % operator, which you have included, does make sense when you consider that % is not quite the same thing in C++ and Python.
In C++, it is the remainder operator, whereas, in Python, it is the modulus operator – and, when the two operands have different signs, these aren't necessarily the same thing. There are some fine explanations of the difference between these operators in the answers to: What's the difference between “mod” and “remainder”?
Now, considering this difference, the rounding (truncation) modes for integer division have to be as they are in the two languages, to ensure that the relationship you quoted, (m/n)*n + m%n == m, remains valid.
Here are two short programs that demonstrate this in action (please forgive my somewhat naïve Python code – I'm a beginner in that language):

QUESTION
In light of recent malware in existing npm packages, I would like to have a mechanism that lets me do some basic checks before installing new packages or updating existing ones. My main issue are both the packages I install directly, and also the ones I install indirectly.
In general I want to get a list of package-version that npm would install before installing it. More specifically I want the age of the packages that would be installed, so I can generate a warning if any of them is less than a day old.
If I could do that directly with npm, that would be neat, but I'm afraid I need to do some scripting around it.
specific use case:
If I executed npm install react-native-gesture-handler on 2021-10-22 it would have executed the post-install hook of a malicious version of ua-parser and my computer would have been compromised, which is something I would like to avoid.
When I enter npm install react-native-gesture-handler --dry-run, it only tells me which version of react-native-gesture-handler it would have installed, but it would not tell me that it would install a version of ua-parser that was released on that day.
additional notes:
- I know that
npm i --dry-runexists, but it shows only the direct packages. - I know that
npm listexists, but it only shows packages after installing (and thus after install-hooks have already done their harm) - both only show packages version and not their age
- I do not know how I would get a list of packages that would come with a install-hook before installing them
- pointers to alternative ways to deal with malicious npm packages are welcome.
- so far my best solution would be to do "--ignore-scripts" but that would come with it's own set of problems
ANSWER
Answered 2021-Dec-07 at 07:26To find out the malicious package, you will need a script that will check your package for vulnerabilities against national vulnerabilities database
The National Vulnerability Database includes databases of security checklist references, security related software flaws, misconfigurations, product names, and impact metrics.
Mostly all software companies use application security tools like Veracode, Snyk or Checkmarx that does this usually in a stage before deployment in the CICD pipeline.

QUESTION
I am trying to encode a small lambda calculus with algebraic datatypes in Scheme. I want it to use lazy evaluation, for which I tried to use the primitives delay and force. However, this has a large negative impact on the performance of evaluation: the execution time on a small test case goes up by a factor of 20x.
While I did not expect laziness to speed up this particular test case, I did not expect a huge slowdown either. My question is thus: What is causing this huge overhead with lazy evaluation, and how can I avoid this problem while still getting lazy evaluation? I would already be happy to get within 2x the execution time of the strict version, but faster is of course always better.
Below are the strict and lazy versions of the test case I used. The test deals with natural numbers in unary notation: it constructs a sequence of 2^24 sucs followed by a zero and then destructs the result again. The lazy version was constructed from the strict version by adding delay and force in appropriate places, and adding let-bindings to avoid forcing an argument more than once. (I also tried a version where zero and suc were strict but other functions were lazy, but this was even slower than the fully lazy version so I omitted it here.)
I compiled both programs using compile-file in Chez Scheme 9.5 and executed the resulting .so files with petite --program. Execution time (user only) for the strict version was 0.578s, while the lazy version takes 11,891s, which is almost exactly 20x slower.
ANSWER
Answered 2021-Dec-28 at 16:24This sounds very like a problem that crops up in Haskell from time to time. The problem is one of garbage collection.
There are two ways that this can go. Firstly, the lazy list can be consumed as it is used, so that the amount of memory consumed is limited. Or, secondly, the lazy list can be evaluated in a way that it remains in memory all of the time, with one end of the list pinned in place because it is still being used - the garbage collector objects to this and spends a lot of time trying to deal with this situation.
Haskell can be as fast as C, but requires the calculation to be strict for this to be possible.
I don't entirely understand the code, but it appears to be recursively creating a longer and longer list, which is then evaluated. Do you have the tools to measure the amount of memory that the garbage collector is having to deal with, and how much time the garbage collector runs for?

Install deal
You can use deal like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
