    Feasibility of Software Idea for Film and Television Post-Production

    Posted: 23 Aug 2018 09:31 PM PDT

    Hi all. I'm not a programmer, but I'm seeking some general input:

    I've worked as a promo editor in television for 10 years, and I think there's high demand for a software based assistant editor. One of the primary tasks on any editing assignment is reviewing the material and collecting "selects" of shots, sequences and dialogue you're likely to use in editing. I suspect this task can be mostly automated with today's technology. For instance, using image recognition, voice-to-text, and a collection of algorithms a movie could be "fed" into the program and the software would identify key moments in the film, such as good closeups (always needed for b-roll), clear audio bites right after a music drop (usually something important being said), guns, sex, explosions (all the obvious stuff that a trailer needs) etc. The language of film is pretty universal to the point that a lot of what's important should be identifiable to a machine using the right algorithms.

    So my question is, how feasible is programming something like this? And are there limits to current technology that would make this impractical? Can reliable image-recognition be built into stand-alone software? Or does it require resources like Google and hardware-intensive machine learning? Could such software scan a movie and pull a selection of shots in a short period of time? Or would it require hours and hours of processing?

    If you have any insight, I'd appreciate your thoughts. Thanks!

    Can I use something like newsAPI (which uses google news) to access my personal newsfeed?

    Posted: 23 Aug 2018 02:57 PM PDT

    I thought it'd be fun to make an autotldr bot that gave me the news feed but abbreviated. Is there some way to access the specific articles suggested for me?

    How to consume content created in html wysiwyg editors? E.g. wordpress posts from its REST API

    Posted: 23 Aug 2018 06:40 PM PDT

    How do you ideally consume content from editors such as tinymce, quilljs, slate, etc? What I mean is, say you want to use rich text outside of the editor itself but you want to use the editor to create the text.

    Do you send back the content as an HTML string and render it right into your app? If so, what if you need to change the output (and associated css) to match the brand (look and feel) of the area where you want to display it? Example: emails, web pages, or wherever

    AngularJS Metadata with dynamic async content

    Posted: 23 Aug 2018 01:00 PM PDT

    I have an angular application running within a .net application and I am trying to implement meta tags for SEO and other purposes. The problem I'm having is that I don't know the page title etc until after a call to an external site.

    For example, a URL I might navigate to is www.mywebsite.com/people/1234. This would make a call to www.apiwebsite.com/api/person/get?id=1234 which will then return information such as name to be used in the title of the page and other important metadata.

    The problem here is while this works from a users perspective, crawlers and open grid won't wait for that information and so only the websites default metadata is visible.

    I have looked at server side rendering for angularjs (angular 1) as an option but was unable to find anything usable, is anyone familiar with something I can use to ensure the correct data for the page is provided to search engines etc?

    Please help me use this tool "TwitchViz" to analyze Twitch-Streams for my thesis ...

    Posted: 23 Aug 2018 12:45 PM PDT

    Hi AskProgramming, I am a complete noob, so please bear with me.
    For my bachelor thesis (social sciences) I want to analyze a Twitch-stream and for this purpose I am trying to get this tool called TwitchViz to work. I have installed git and then cloned the whole thing (not sure if that was even necessary, could I have just downloaded it?) ...

    I am now trying to figure out if and how I can feed it the VOD of a specific stream. I tried editing the "connectTwitch.html"-file and entered a stream id where it says "YOUR STREAM HERE" and then saved that and opened index.html but no video was loaded. I am unsure how this is supposed to work anyway. Shouldn't I be entering the address of a single VOD and not a whole stream?? I am completely lost and could really use some help ...

    I need to modify a wordlist without hashcat or john the ripper

    Posted: 23 Aug 2018 10:58 AM PDT

    I have this to append 1-9999 to each line:

    for i in $(cat wordlist1.txt) ; do seq -f "$i%0.0f" 0 9999; done > wordlist2.txt

    but is there some way this can include numbers with zeros before them? The pattern would be something like:

    1

    2

    01

    02

    10

    11

    001

    002

    010

    011

    100

    ...

    Also if there's something I can run in terminal that is more efficient (my vm has trouble with wordlists over 1mb), do tell.

    Calculating the degree of change in a list of numbers as we add new numbers, and act accordingly

    Posted: 23 Aug 2018 05:53 AM PDT

    Maybe this is going to sound pretty abstract but that's just because even though I know what I need, I don't know how to do it. I just lack the mathematical and statistical expertise.

    Ok so I have a collection of N objects that are processed and this produces a result that can be measured as "number of elements in certain state", let's call it R. The goal is to have 0 elements in that state. So if we don't achieve the goal, the process is run again from scratch hoping that a better result will be found (yeah it's pretty random but that's what I'm working with). Since this can potentially run forever if the goal is not achieved, we set a limit to the number of total iterations. Let me quickly sketch this:

    it = 0 while R > 0 and it < limit: R = process(elements) it += 0

    Now, often the result just doesn't get better because of the nature of the elements. So all attempts are pretty much for nothing. I would like to put a stop with this, but here is the problem: how do I measure if further attempts are producing better results?

    For instance, we run the process 10 times and get the following array of results: [8, 8, 9, 10, 8, 7, 7, 8, 8, 11]. Should we have stopped earlier or not? Hard to tell. How can we tell? Well, probably the total number of elements N is relevant, so I guess it should be taken into account in the measurement. If N=200 the results tell a much different story than if N=15. In the first case we should have probably stopped in the 2nd or 3rd attempt, but in the second case we should probably keep trying.

    Also if results get increasingly smaller, i.e. [8, 9, 7, 7, 6, 6, 5, 4, 5, 3] then we should probably "rate the decision to continue the loop" higher than if it was stalling (example above) or getting increasingle bigger (in this case we should probably rate the decision the opposite way: lower its chance).

    But how can I actually measure the degree of change in the array of results? I have pondered using standard deviation but I am not sure how to go from that. Also standard deviation is an absolute measure, I would need to normalize it but not sure how, perhaps using N? I have tried results.std() / N but they don't seem to produce a normalized rating.

    A very important thing to consider is that I also need to identify the trend, so the standard deviation is not enough. Getting lower results must be evaluated differently than getting greater results. What I mean is that the standard deviation for [10, 11, 14, 10, 9, 3] is 3.30, and for [4, 5, 4, 7, 7, 4, 16] it is 3.98, so while they are pretty similar, the scenarios are pretty different:

    • the first one is a "bad" sequence of results where a really good one is finally found

    • the second one is a "good" sequence of results where a really bad one is found

    Another scenario to consider is the following: in a more or less stalled or not very promising string of results we suddenly get a VERY good one, picture [10, 12, 9, 10, 10, 11, 3, ...]. 3 is so good compared to the average that we should probably just stop altogether since we are probably not going to find a better result. I guess this would be pretty easy to implement by just comparing that result R to the average result using a given threshold (let's call it e for epsilon): (results.mean() - R) / results.mean() < e where e=0.5 for a 50% increase. I hope I got that right but something tells me I did not.

    Suggestions?

    I went from C++ to C# and have a few questions about what my guide didn't answer

    Posted: 23 Aug 2018 09:27 AM PDT

    First question: When declaring a class or array why do i need new and what does it do in the following?: 

    Box Box1 = new Box(); int Ar[] = new int[5];

    Second question: I'm using Visual Studios Community and I've mainly done things in the console is there a great resource for learning to make a display that can take inputs and spit out an answer. I'm talking about making a simple display.

    Map IP addresses to corresponding subnets

    Posted: 23 Aug 2018 06:42 AM PDT

    I have extracted a list of IP addresses from a capture (using scapy), and I want to map them to the corresponding subnets (that are specified a priori).

    For example, there are N total IPs in the capture, and I let the algorithm know that there are 2 subnets: /16 and /21, so basically it has to assign a subset of those N IPs to the /16 network, and the other to the /21.

    I have tried to construct different trees, but I am getting stuck, because there are many cases to be covered (tried pencil & paper).

    I have also tried a longest-common-prefix approach on the list of IPs converted to 32bit binary strings. Then, if lcp is of size, say, 22 and I want to find 3 /24 nets, then I have 2 bits to play with (24 (mask) - 22 (lcp)), that give 00, 01, 10, 11, and then I group by these.

    But things get complicated when I have, for example, a /15 and a /24 net. Suppose lcp is of size 8, then another 7 bits form the common prefix of the IPs from the /15 net, and another 16 bits form the common prefix of the IPs from the /24 net. How do I find these 7 and 16 bits?

    Maybe I am overthinking this problem, but how would you approach this?

    Change log tools

    Posted: 22 Aug 2018 11:15 PM PDT

    Looking to maintain a change log on production pushes. The target audience would be customers (we're a B2B SaaS company so we have a technical user base) and internal stakeholders. Ideally there would be easy e-mail notifications, slack integration and some sort of API so our web page can show it too.

    What’s the best option, Visual Basic or C#?

    Posted: 22 Aug 2018 11:59 PM PDT

    Hello! I was wondering what would be better, I have entered a project in which they want me to update an application made in Visual Basic, as of know I have no major experience in it and was wondering if I should play it safe and try to work on a code that left me flabbergasted (literally there's more than 50 forms and god knows why it starts on form 36)

    So I want to know if I should try Visual Basic or develop an app in C# since I have experience using it and start from scratch.

    I would like to know your own opinion of what's the best choice nowadays!

    Thanks in advance :)

    Edit: guess i didn't say enough about the project! It's an interactive test for ubicating students in levels of French, they want me to "update" until x level since there are new books being used and the new test is based on that book, my main problem reviewing the code is how the forms are structured, I feel like it would be an awful waste of time trying to make sense of a program left by another developer two years ago.

    I'm trying to give a better product, which I feel I can achieve starting from the beginning but that's my own naive self, which is why i want to know your opinion on the current state of both languages and know knowing more about the project itself, what's the course of action you would take based on your own experience.
