QUESTION
Suppose we have two std::collections::HashMap
-s, say HashMap
and HashMap
, and a function Fn(V1, V2) -> R
.
How do I perform an inner join on these hashmaps so that I get HashMap
on their shared keys as a result? Here's a reference implementation to illustrate what I mean:
ANSWER
Answered 2021-Jun-06 at 01:58As the answer you linked mentions, for a hash table, which does not have an inherent ordering, there is no way to do this more efficiently. (Using the hash codes of the objects do not help, because unless you've used an alternate hasher, every HashMap
uses a different hash function, to prevent denial-of-service attacks which submit deliberately colliding hash keys.)
There is one high-level improvement you can make to the algorithm: iterate over the smaller of the two hash tables, since that requires the fewest lookups.
If you have a sorted collection, such as a BTreeMap
, then itertools::Itertools::merge_join_by
can help you implement a merge of sorted data:
QUESTION
I have a question about the magic variables. Are these true variables or are they a type of function call? Being as how PHP is an interpreted language I am very picky about how I assign variables. I do not like to call a function multiple times if I can store the response in a variable and reuse it without costing the CPU time over and over. Currently, I assign DIR to a local variable and use that variable for all of my includes and anything that requires a current directory path. I am wondering if this is saving CPU time for running a function. I have spent some time looking around the internet but I can't find anything that says how these magic variables are assigned.

...ANSWER
Answered 2021-May-26 at 16:50All these "magical" constants are resolved at compile time, unlike regular constants, which are resolved at runtime.

So no, you are not saving any CPU time

I have access to a virtual machine with Ubuntu 20.04 setup and GPUs. Sysadmins already installed latest Cuda drivers, but unfortunately that's not enough to use GPUs in Tensorflow, as each version of TF can be very picky when it comes to the particular set of Cuda Toolkit + CuDNN versions. I don't have sudo rights, so I need to install everything locally.

QUESTION
I am trying to build and install kernel modules for a network card, from source. The module sources seem very picky in terms of which kernel version they can compile against.
I have managed to build the modules against the LTS kernel headers for my distribution, Arch Linux, which at the moment are linux-lts-headers 5.10.37-1
. Does this mean that I need to actually install and boot this exact same kernel version, to use the modules? Or do the modules have some tolerance between the booted version and the version they were compiled against?
I realise this is dependent on what exactly I'm building but I'm interested in common practice, do's and don'ts. For example, for a rolling release distro it would be a lot of work to rebuild the module with every minor mainline kernel update, for example right now linux-headers 5.12.3
-> linux-headers 5.12.4
. Pointers appreciated.
ANSWER
Answered 2021-May-20 at 12:20That's why you usually never find prebuilt kernel module distributed somewhere. You have to build kernel module with kernel headers of your running kernel. Common practice is always having the right kernel headers in your /usr/src
QUESTION
(Edited the title because I had no idea what I was looking for and it was misleading.)
Edit: What I was looking for was binary to string and back again. I have answered my own question below.)
Original Post: I'm trying to make a retro-style password system for a game made with JavaScript. (like on an old NES game for example that uses alpha-numeric characters to load the level you were on or all the flags pertaining to that level.)
I've gotten so far as generating a string of flags (all numeric) and then loading that string later by sorting through those flags with regex and then putting them back into my gamestate object (with objects in it that hold all my various flags).
Each flag is a number between 0-9 and each object (or group of flags) are 8 characters long. (often with leading zeros, so these groups are always 8 characters long)
A typical string could look like this:
var gameStr = "000102340000001000019531";
ANSWER
Answered 2021-May-08 at 19:08Where does the initial state that you want to compress come from? I guess there are three likely options.
It's random. Most likely that means some code seeded a pseudo random number generator using some value like e.g. the time of the day, then used that to produce the values. In this case, you could get your hands on the seed (which most likely would be a fairly short number) and use that as the identifier from which everything else is computed. Make sure to use a portable random number generator with well-defined deterministic behaviour, e.g. some Mersenne Twister implementation. The JavaScript built in number generator is implementation-defined so it does not fit this bill.
It came from some catalog made by the game developer (i.e. you). Then just obfuscating the index into that catalog might be good enough.
It came from some user hand-tuning the values. In this case you're out of luck, since as I understand the problem chances are that any possible combination could get entered. You can't compress a large set of values to a smaller set of values without losing information.
There might be middle grounds. You could have a randomised setup that subsequently got hand-tuned, and the description as initial seed plus a few modifications would be shorter than the full set of settings. Or the hand-tuning would only be allowed following specific rules set out by the game developer, which again would make for a limited set of possible values and a potentially shorter encoding. Thinking along these categories might help you analyze your own situation and find a suitable solution.
You can also look at this from an information theory point of view. You can't expect to encode a sequence of fully independent and uniformly distributed digits with less information than those digits, perhaps expressed in some other base or whatever. You can compress data if there are patterns to it that make some combinations more likely than others. The more you tell us about these patterns, the better we might be able to advise. In total you can't get below the entropy of the source (i.e. game state distribution), so estimating that might help you find a lower bound for what to expect.

QUESTION
Im really struggling with this question, asking it right and even proper terminology so please help me out here. This is probably an easy fix under the proper question syntax that I'm unaware of. If so I'll delete once I know the lingo.
Goal
I want to dynamically add data to my Syncfusion DataGrid.
Problem
- I don't know how to get my List of dynamic data to my DataGridSource
- Can't use Provider, Consumer etc because of no context in class
- Don't know how to add arguments to class constructor when calling type in DataGrid Consumer in Widget, I don't see any possible way to get an argument into the Consumer as DataGris source is picky about what it gets
- creating instance of my database class and injecting data into DataGrid source is not working at all, the data does not load
- I can see that ultimately this is a state management issue, therefore if I learn only one thing here I would like to learn how to pass data to a class independent of any widget without standard messy OOP initializations
- Note, i did attempt using proxy provider for initializing the database data method- no worky
If my questions don't make sense I can try to expand. However all i want to do is use Consumer to DYNAMICALLY add data to DataGrid.
Here is Syncfusions coded example for me using consumer with hardcoded data.

QUESTION
I have been troubleshooting on this for an hour or two now, sometimes guessing with certain parameters and their values with the streams.filter()
method. I want to fetch a mp4 video without its audio attached. You'd think this may be easy, but it isn't, at least for me.
The streams filter parameters, are listed and present some ones that stick out for what I want to achieve. only_video
, mime_type
, or maybe res
and fps
. You can read their descriptions to get an idea of what they will do.
Now, applying parameters together basically means you well, are filtering your available options based on your filter. The options will specify the above objects and more as it's is own download preset if you will. To actually pick one, you can use first()
, last()
, get_highest_resolution()
, etc, to settle on your desired download.
I have tried several parameters some of them listed above, to get a silent video that isn't 5 seconds long with this:

Answered 2021-Mar-19 at 20:28ANSWER or EXPLANATION
After fiddling with this some more. Using only_video=True
doesn't seem to be compatible with certain methods that are appealing to include for a good video. However, it seems as of now only using pytube, you can get a full length video that isn't corrupted but only in 360p.

Flexbox is good. But one problem bothers me.
Can flexbox deal with images of arbitrary aspect ratio?
I want to limit the height of a flexbox, don't make contents overflow because of image being too big, but still, try to maximize the image, and preserve aspect ratio at the same time.
Is this possible? Or there's a better way to do it?
Correct me if I'm just too picky. Maybe we just don't have to consider arbitrary aspect ratio when designing web pages? Taking care of wide images & long images at the same time?

QUESTION
I'm building a retry system that allows me to attempt code multiple times before giving up (useful for things like establishing connections over the network). With this, the basic code I usually copy and paste everywhere as a base is:
...ANSWER
Answered 2021-Feb-24 at 03:35You can do away with the stack-based security by introducing a context object that provides access to the event.
But first, a few notes. I'm not going to speak to the merits of this design because that's subjective. However, I will address some terminology, naming, and design matters.
.NET's naming convention for events does not includethe "
On
" prefix. Rather, the method that raises the event (markedprivate
orprotected virtual
, depending on whether you can inherit the class) has the "On
" prefix. I've followed this convention in the code below.The name "DelegateFactory" sounds like something that create delegates. This does not. It accepts a delegate and you're using it to perform an action within a retry loop. I'm having a tough time word-smithing this one, though; I've called the class
Retryer
and the methodExecute
in the code below. Do with that what you will.DelegateWork
/Execute
return abool
but you never check it. It's unclear if that's an oversight in the example consumer code or a flaw in this thing's design. I'll leave it to you to decide, but because it follows theTry
pattern to determine if the output parameter is valid, I'm leaving it there and using it.Because you're talking about network-related actions, consider writing one or more overloads that accept an awaitable delegate (i.e. returns
Task
). Because you can't useref
orout
parameters with async methods, you'll need to wrap thebool
status value and the return value of the delegate in something, such as a custom class or a tuple. I will leave this as an exercise to the reader.If an argument is
null
, make sure you throwArgumentNullException
and simply pass it the name of the argument (e.g.nameof(work)
). Your code throwsArgumentException
, which is less specific. Also, use theis
keyword to ensure you're doing a reference equality test fornull
and not accidentally invoking overloaded equality operators. You'll see that in the code below, as well.
Introducing a Context Object
I'm going to use a partial class so that the context is clear in each snippet.
First, you have the events. Let's follow the .NET naming convention here because we want to introduce invoker methods. It's a static class (abstract
and sealed
) so those will be private
. The reason for using invoker methods as a pattern is to make raising an event consistent. When a class can be inherited and an invoker method needs to be overridden, it has to call the base implemention to raise the event because the deriving class doesn't have access to the event's backing storage (that could be a field, as in this case, or perhaps the Events
property in a Component
-derived type where the key used on that collection is kept private). Although this class is uninheritable, it's nice to have a pattern you can stick to.
The concept of raising the event is going to go through a layer of semantic translation, since the code that registers the event handler may not be the same as the code that calls this method, and they could have different perspectives. The caller of this method wants to post a message. The event handler wants to know that a message has been received. Thus, posting a message (PostMessage
) gets translated to notifying that a message has been received (OnMessageReceived
).
