What are some GOOD programming podcasts/audiobooks???

>>59646055
They've been trying to do that for ages.
https://en.wikipedia.org/wiki/Intel_iAPX_432
that was designed back in 1975.

So I upgraded from my Debian system's gcc 4.9 to gcc 6.3. Then since I figured I ddin't need the system's gcc anymore I removed it with apt. But now I pretty much can't build any C++ program anymore. For example when i do

#include <iostream>

int main()
{
    std::cout << "hello world\n";
    return 0;
}

I get

main.cpp:1:20: fatal error: iostream: No such file or directory
 #include <iostream>
                    ^
compilation terminated.

Same with clang. According to apt, libstdc++6 is still installed. What do?

Managed to solve it thanks to the first reply. I tried to find whether the packages were installed somewhere or not and dpkg -i them. However it turns out clang builds against g++'s libraries on Linux. So when I saw the following line in clang++ -v

Selected GCC installation: /usr/local/bin/../lib/gcc/x86_64-pc-linux-gnu/6.3.0

I just had to look into the folder and notice that it was basically empty.
It turns out when you build gcc, it only builds and installs the bare minimum. So the solution was to copy and build the content of libstdc++-v3 in gcc's folder.

>>59646199
I thought about doing that, but a shitton of packages depend on the libstdc++6 so I kind of kept it as a last resort.

This feels written by someone who only has a vague idea of how computers actual work. In todays modern CMPs with multi-level cache systems, it's hard enough to just keep them coherent. Just implementing a GC system on top of that would be an incredibly complex undertaking (requiring probably decades of research, and even more time to put into production), and would probably not even net you an advantage. Accessing cache (i.e. miss) or god forbid memory is already on the critical path for virtually any program.

That doesn't even take into account the maturity of compilers, programming languages ect, that would need to be re-assessed, and the fact that all consumer level HW manufacs would need to sign on to some standard, and the fact their would be no backwards compatibility (i.e. forced into original situation, if run-able at all) if it did happen, ect ect

>>59646616
Do you have a better idea how to move many objects (I'm thinking 10k? Maybe it's a bit too high) and display them with a more traditional approach? The thing is I also have to account for collision checks, thus I figured not having to change the player's coordinate for each test was better.

>>59646685
All he's saying is that you need to optimize for what your actual access patterns are and not just make things structure of arrays willy nilly. You're probably correct to do so in this case, that being said.

Optimizing collisions is mostly about doing a gauntlet of increasingly precise tests. How you structure the data is likely not significant.

>>59646708
So?

>>59646725
That would make the code a lot more lengthy, but yes, of course.

>>59646745
You can use numerical methods for solving integrals: Monte Carlo, trapezoids and so on.

>>59646596
You are incrementing count whenever the two overlapping matrix positions are equal, correct? So, if this was working correctly, it would do 16 comparisons, and only 15 should come out to be correct. But you only ever do 4 comparisons (obviously), and they all come out to be 'true'. With that, you should be able to tell what the problem is.

So?

Last night I spent an hour trying to get a bluetooth ODBII dongle to connect to this scantool program that I found. I got the dongle to pair, but I couldn't get it to connect to scantool, because scantool is some old DOS tool that was modified to see USB tty devices, /dev/ttySX iirc, as COM1-8. The hackiness of the solution appealed to me.

I was apparently able to bind the dongle to a new device, /dev/rfcomm01 using some tool whose name I am forgetting right now, but I couldn't find the place in some scantool source where the COM ports were mapped to these USB devices.

mapping the dongle to the USB devices didn't produce an error when I ran the command, but also didn't work when I ran scantool.

I also wasn't able to get it to connect with bluetoothctl, but apparently Bluez5 needs some work... I'lll play with it further when I have more time.

Do any anons have any resources?

It's the core of the efficient algorithms for calculating ray tracing.

>>59646678
just start writing and google the things you don't know. that's how I did it.

>>59646691

>>59646879
Okay? That still adds to the complexity of the code. My point was that you can program a very simple ray tracer in a very small amount of code and still get a nice image, it's just not going to be fast.

Making that assumption is why you suck at programming things on the Internet.

That's just not true.

>>59647109
somebody said that this is shit

>>59647131
or at least a symptom of your general way of thinking that is why you suck at programming things on the internet.

>>59647052
Because even though shit is super fast, packet loss is still a thing. packets sent with TCP are tracked so no data is lost or corrupted in transit. If it is interrupted it must re-establish the connection.
If you arent downloading something. or ensuring that data is sent in tact use UDP. Basically Video, VOIP, Streaming media kinda shit is best to use UDP.

I have n random points uniformly distributed over -1 and 1. I also have the unit circle. What would be the most efficient way to loop through these numbers (stored in an array x and an array y) to determine if they fall within the circle?

I'm using MatLab so there could be some sort of function I'm unaware of. Either way, my geometry is quite rusty and I can't think of a way to do this.

    }

Trying to figure out a better way to do this. apparently instanceof is bad practice.

Book and Magazine inherit from Product in this case. I want to add them to a HashMap in a way that I can count the amount of something and not have duplicates.

How should I do this instead?

0 is a number? a number. is infinity a number? is undefined a number? then how come when you operate on numbers, you supposed to get some bullshit non-number? when horse fucks horse, it doesn't produce a cat. WHAT THE FUCK???
we should change math to work this way:

Well I guess I would ask what you mean by analysis then. You mean like machine learning, i.e. semantics/classification? Or grouping data in particular ways to look for correlations (like word counts vs post time, ect)?

A lot of components in video games can be easily represented as functional reactive components (basically just time/input dependent state machines). Real mutability of course is required for the meatier parts of game play (e.g. physics), so you would need a non-functional core.

>>59647868

Magazine and Book should share a parent class, and whatever object you use for storing the stock has a collection of the parent class, so you can add a book or magazine to the same collection.

>write low-level hardware interface

I'm writing a desktop application for my dad to help keep track of jobs (customer name, address, billing status, payment status, etc) in C#.

What's the best way to go about storing all of this shit? I've been thinking about make a Job class that has a List<string> of all the info for that particular job, but I'm not sure what the best method for organizing all of the individual Job s. Should I make another class with a List<Job> to hold them all?

This is all in C# BTW. Also is MVVM worth it or is it just a giant fucking piece of shit like I'm beginning to suspect?

MVVM is worth it because:

- You can trade out the UI later on without any under the hood changes

- You can unit test your code

- You are forced to seperate business logic and the UI.

Sorry man. I've got a C# guru at work who helped me understand it. Honestly best thing you can do is read some code as an example, that is what will teach you best. Not really sure where you can get your hands on some though. Basically.

View: Your UI, you will have OnClick and what not strewn through here which should simply call registered callbacks.

Model: Your data, so perhaps the database with jobs, addresses etc

ViewModel: Your core business logic code is implemented here, it's the code that reaches into the database to do things and also offers functions as callbacks for the view to call.

Next step will be eliminating duplicate post which will be needed for the slower boards. Shouldn't be too difficult.

Then the analysis. I am still building and deciding the analysis tools and method that I should use.

basc-py4chan. I was doing it in BSoup till someone mentioned it a while back and I looked it up.

What I was planning was to just do a simple count for each board first and then divide it accordingly to the volume of post. That way it gives me two things, the highest concentration of reddit (highest hits/post) and then the highest volume of reddit (simply highest amount of hits irregardless of volume).

>>59648261
Well we don't care about how much apple is left, we care about how much we have distributed to everyone.

It isn't the challenging part nor is it the interesting part. It is the most time consuming part because it to run for a week to gather data so the sooner I get it running the better so I can do the interesting part.

While I am arguing with morons like you here that have autism and don't seem to understand the purpose of do simple stuff fast, I am also researching how best to analyze the data, how to compare the image file md5, how to build a database for comparison and how I should conduct my analysis using tried and tested methods. That is the fun part. Not fucking rewriting my own wrapper in another language for 4chan API. That is for autistic people like you.

The language doesn't matter. What matters is the entire process, from how data is being collected, to how its stored, then finally processed and presented.

You see the goal as just getting the processed data. When you should be worrying about the whole picture.

>>59648940
Funny that you saved so much time bringing in python to handle that tricky API call, but are sitting here arguing for so long.
