    Among computer scientists, is the Sloot Digital Coding System actually considered a lost invention? Computer Science

    Among computer scientists, is the Sloot Digital Coding System actually considered a lost invention?

    Posted: 27 Jul 2020 06:14 PM PDT

    I came across the Sloot Digital Coding System on a list of "lost inventions." What I read indicated that in the late-90s, it was able to play multiple movies at once using much less memory then we could compress such files even today, 20 years later. The former CTO put out something saying it isn't about compression; it was a whole different way of thinking. But it sounds like this wasn't widely demonstrated; I only find a reference to a demonstration to a Phillips exec, the company they were "just about to" sign a deal with when the inventor died. Afterward, a floppy disk was missing, so the whole thing is lost. Which all, frankly, seems like BS to me. An invention back then so much better than anything today, like saying you could build a 747 that only weighed 1/5 of the weight. One disk of code lost, but nothing left in terms of the underlying theory or other info to sketch out how it was done? No partner knowing how it worked? Not enough for others to try to "solve" this lost mystery, given how great the performance was? And no one really sees it working? It all sounds like it was going to be a scam... makes me think Theranos and the like. But, there may be something I'm missing to this. So, wanted to ask a community of people who think of this stuff more than I, is this considered a real invention that was lost among the computer community? Is there evidence of it existing/working beyond what I mentioned?

    [R] Adobe and Stanford Unveil SOTA Method for Human Pose Estimation

    Posted: 27 Jul 2020 12:28 PM PDT

    In the recent paper Contact and Human Dynamics from Monocular Video, a research team from Stanford University and Adobe Research proposes a new approach that combines learned pose estimation with physical reasoning through trajectory optimization to extract dynamically valid full-body motions from monocular video. The researchers say the approach produces motions that are visually and physically much more plausible than state-of-the-art methods.

    How do I defend myself against DDOS Attacks

    Posted: 28 Jul 2020 03:55 AM PDT

    I'm aware that this may be the wrong subreddit, but for lack of knowledge on what other sub to post this on, I'm just gonna post it here. If anyone knows what sub to post this on, please tell me below.

    Well, there are some not-so-nice people at my school, and they have managed to get my IP address. Not sure how, but they have it.

    And ever since then, they have been overloading my router with requests ( I think that's how it works) and it stops working. Lasts for five minutes, pauses for thirty seconds.

    I have since deleted the app which they used to get my ip, but that doesn't matter since they already have it. A mate of mine told me to change my IP address, so I watched a video on how to do it, and I did. But alas, the fuckery only stopped for a day or so; when I thought all was well, it stopped working again, lasted for five or so minutes, paused for thirty seconds.

    And I'm not sure what to do to prevent this, I have deleted most of the apps from my phone, yet they still got my new ip.

    If anyone knows how to prevent this from occurring, please tell me how. As I feel as if I have tried everything, but apparently not.

    What Is Significance In Statistics And Why Is It Important

    Posted: 27 Jul 2020 10:04 PM PDT

    Using word classifiers to calculate sentiment

    Posted: 27 Jul 2020 09:17 PM PDT

    Using word classifiers to calculate sentiment

    By identifying and computing the word classifier – noun, verb, adjective, pronoun, adverb, preposition, etc. – for each word in a sentence, we can form some generalized assumptions about what is communicated by the written source. In fact, we can quantify classifiers of any sentence to create acceptable conditional statements that correspond with personal interpretations. But first, context of the written source must be known beforehand and that interpretations will only make sense for that particular topic.

     

    List of compliments, tamed or rude (some words may be classified wrong):

    Example 1

    Sentence: Those are a nice pair of Mona Lisas. (pun intended) Classes: pron v n adj n n pron Totals: n = 3, v = 1, adj = 1, pron = 2, adv = 0, prep = 0 Interpretation: There is at least one adjective to describe, most likely nouns. A couple pronouns are used, signifying some comparison with some well-known name. Because there's at least 1 adjective, it might be a positive compliment.

    Example 2

    Sentence: Your body is a work of art. Classes: pron n v n n v n Totals: n = 4, v = 2, adj = 0, pron = 1, adv = 0, prep = 0 Interpretation: The sentence is talking about a lot of things, nouns specifically. There's no adjective, so this might not be a compliment easily. However, the sentence is a compliment with metaphor. Caution should be exercised if these kinds of sentences will be extracted.

    Example 3

    Sentence: Annoying or not, this chick is way hot! Classes: adj prep adv n n v adj adj Totals: n = 2, v = 1, adj = 3, pron = 0, adv = 1, prep = 1 Interpretation: Might be a compliment overall.

    Example 4

    It is considered an archetypal masterpiece of the Italian Renaissance, and has been described as the best known, the most visited, the most written about, the most sung about, the most parodied work of art in the world. – Wikipedia Totals of classes: n = 6, v = 14, adj = 5, pron = 2, adv = 0, prep = 11 Interpretation: Verbs make 33% of the sentence. Multiple adjectives appear among the verbs that likely describe actions. This is backed by plenty of prepositions. Hence, this could likely be a critical review with some compliments.

    Example 5

    The painting's novel qualities include the subject's expression, which is frequently described as enigmatic, the monumentality of the composition, the subtle modeling of forms, and the atmospheric illusionism. – Wikipedia Totals of classes: n = 9, v = 7, adj = 4, pron = 0, adv = 1, prep = 7 Interpretation: Nouns, verbs, and prepositions are almost balanced to each other; both combined have an average of 7.67. Adjectives are present too. The balancing of the totals mean the review was carefully articulated, so it may safely be labeled as a compliment.

     

    Given a context, describing a set of class is fairly easy without having to look at the true sentence. You may cover the sentences and try analyzing the class sets again to see if you form your own interpretations of these compliments.

     

    Possibility for sentiment analysis on markets

    Applying this research to market predictions would need a new and extensive research. One must also be knowledgeable of investment vocabularies and lingo to understand market movements.

     

    We analyze the responses of a thread that has a TA chart of Bitcoin's price increase from here https://www.reddit.com/r/Bitcoin/comments/hy90zp/bitcoin_is_moving_fast_now_smashed_through_two/

    Summary of the comments:

    Example 1

    There's some rationale, but trade at your own risk. Classes: pron = 0, n = 5, v = 2, adj = 0, adv = 0, prep = 1 Conclusion: Critique.

    Example 2

    The move is good but not impressive. Classes: pron = 0, n = 1, v = 2, adj = 2, adv = 0, prep = 2 Conclusion: Critique in movements more than nouns.

    Example 3

    No. It hit the target. Both times. Classes: pron = 0, n = 5, v = 1, adj = 0, adv = 0, prep = 1 Conclusion: Lots of nouns. For or against chart analysis?

    Example 4

    The faster the increase, the lower the MC will be. Classes: pron = 1, n = 2, v = 2, adj = 0, adv = 2, prep = 4 Conclusion: Objects described with adverbs and multiple uses of prepositions indicate action.

     

    Then we analyze a reputable news source that may influence price from this Reddit post https://www.reddit.com/r/Bitcoin/comments/hyfkuz/visa_and_btc_mass_adoption_is_getting_closer/

    Responses and replies:

    Conversation 1

    Type: Response Totals of classes: pron = 4, n = 11, v = 8, adj = 1, adv = 0, prep = 3 Conclusion: Lots of verbs. Expresses action. Up or down, unknown. Pronouns with action.

    Reply 1

    Type: Reply to 1. Totals of classes: pron = 2, n = 4, v = 2, adj = 0, adv = 1, prep = 0 Conclusion: Has pronouns. Maybe adding info.

    Reply 2

    Type: Reply to 1. Totals of classes: pron = 1, n = 6, v = 3, adj = 0, adv = 0, prep = 2 Conclusion: Plenty of nouns and 1 pronoun. Maybe adding info.

    Conversation 2

    Type: Response Totals of classes: pron = 0, n = 5, v = 1, adj = 0, adv = 0, prep = 1 Conclusion: No adjectives. Sentence is 71.4% nouns. Probably sarcasm.

    Which major would you prefer for a job perspective and why?

    Codenation Internship Question, So We had this question in our test, for the value update and add part I figure we can use Segment tree, but how do we find aith beautiful number? Thanks in advance!

    Posted: 27 Jul 2020 06:36 PM PDT

    Is there a name for this tree search algorithm?

    Posted: 27 Jul 2020 04:42 AM PDT

    I'm a Software Developer and I cannot remember encountering this algorithm exactly back in college, and I have finding a name for it (but searching for them is hard when you don't know the name). None the less, I have found myself using it for several different problems now.

    ​

    Given a Tree of choices, where several paths can put you in a valid end state but the different end-states can have varying degrees of quality. One can find best possible end-state by applying this algorithm:

    1. Define a function F(x) that can take any node in the tree and return a value that describes how bad the state described by the node is, it's important that for any given Node in the tree, F does not return a lower "badness" value that is lower than it's parent Node.
    2. Start by expanding the root node of the tree, adding it's children to the list of open choices.
    3. Pick the open choice for which F(x) returns the lowest value, removing it from the list.
    4. If the picked choice is a valid end-state, the solution has been found and the algorithm should terminate.
    5. Otherwise, add all child nodes from the picked node to the list of open choices. Go back to step 3.

    ​

    Apologies for the lack of formal language, I have not used that in quite a while. I'm sure this algorithm have been used elsewhere before, that is why I'm asking.

    ​

    Thank you for your time!
