What is `Roland's pitch` and `Yamaha's pitch`? and How to convert notes to them? I have an assign that convert this sheet to Rolands pitch and Yamahas pitch. I have no idea about what is Rolands pitch and Yamahas pitch, neither how to do it. Please let me know. using this image. According to MIDI forum post: The short answer is that MIDI notes are simply a note index and do not really define the pitch of a note. The MIDI specification only defines Middle C as note number 60. So pitch and MIDI are not really connected, so your question requires substantial additional information, such that the problem becomes clear. Middle C, the C written below the treble clef and above the bass clef, has MIDI note 60. Conventionally, this note is referred to as C4. However, Yamaha refers to MIDI note 60 middle C as C3. Another major music equipment company, Roland, refer to this note as C4, as is conventional. Therefore, the first note in your first diagram is G4 in Rol...

Magento 2: Add custom tab to order details page in customer account When a customer clicks on an order on his order history page he is then redirected to the order details page. In Magento 2 standard community edition there is just one tab that list a order summary with all ordered articles. I want to add a custom tab next to the Ordered articles tab the tab might be labled slightly different, I use another language. How can I do that Please notice, I do not want to add a tab to the customer account navigation on the left nor do I want to add a tab to the admin backend. I know that there are plenty of tutorials. This hint is just to avoid misunderstandings.

How to pick rows with higher value only in Hive I have the following data in Hive sorted by Count column: ItemX ItemXX Count ----- ------ ----- item1 item11 8 item1 item12 2 item1 item13 1 item2 item21 10 item2 item22 1 item3 item31 9 item3 item32 7 item3 item33 5 I need to filter max Count lines only. Like this: item1 item11 8 item2 item21 10 item3 item31 9 How can I do this in Hive QL Use row_number function: select ItemX, ItemXX, Count from select ItemX, ItemXX, Count, row_number overpartition by ItemX order by Count desc rn from table_name s where rn1 In common cases without sorting you can use these queries: -- 1. SELECT a. FROM tbl a INNER JOIN SELECT ItemX, MAXCount Count FROM tbl GROUP BY ItemX b ON a.ItemX b.ItemX AND a.Count b.Count; -- 2. SELECT a. FROM tbl a LEFT OUTER JOIN tbl b ON a.ItemX b.ItemX AND a.Count b.Count WHERE b.ItemX IS NULL;

Intuition behind successive squaring. I was looking at the successive squaring method used commonly in modular exponentiation problems and was wondering why we are able to square the remainder of successive powers of a number. For example for 7327 mod 853: 71 equiv mod 853 72 equiv 49 mod 853 49 74 equiv 492 mod 853 695 78 equiv 6952 mod 853 227 ... 7256 equiv 6282 mod 853 298 During this operation, why is that we square the remainder and how do we know that doing so will relate to the final answer Im struggling to understand the intuition behind this strategy and why this actually works. You are trying to arrive at the answer with as little computation as possible. You could have arrived to the answer by multiplying 7 mod853 to itself 327 times. But that will take forever. Now, note that any integer 327 for example can be expressed in binary. For example, 327 101000111_2. This means that 327 1 2 4 64 256. If you somehow had the values of 71, 72, 74, 764, 7256 mod 8...

Showing that if the limit of norms converges, then the sequence converges Let H be a hilbert space, and C subset H a convex set. Let x_n_nin mathbbN be a sequence in C with lim_nto inftyx_n inf_xin Cx. Show x_n converges in H. So far I have: Let P_C0 x in C: x inf_x in Cx be the projection of 0 onto C. If we consider barC the closure of C, then there is a theorem that tells us since barC is closed and convex, there is exactly one y in barC with yP_barC0, i.e., y inf_xin barCx. Since the infimum of a sets closure equals the infimum of the set, we also have y inf_xin C x. Now, I need to show that since the norms converge to the norm of a unique element y, the sequence itself must converge to this element. This makes sense intuitively, but I cant make it rigorous Any hints would be appreciated. x_n-x_m2x_nx_m22x_n22x_m2. Denoting inf_xin C x by A we get limsup x_n-x_m2 leq 2A2A-liminf 4frac x_nx_m 22.

Is there a physics limit to data transfer rate? Is there a physics limit to data transfer rate for a USB 3.0, the rate can be a few Gbit per second I am wondering if there is a physics law tells us there is a fundamental limit to data transfer rate, similar to how the 2nd law thermodynamics tells us perpetual motion never going to happen; and similar to how relativity tells being faster than light is impossible No, there is no fundamental limit on overall transfer rate. Any process that can transfer data at a given rate can be done twice in parallel to transfer data at twice that given rate.

Where should I start building the community for a new Stack Exchange site? Changes have been announced to how Area 51 works in the future. Robert describes how the goal is to bring an existing and active community to Area 51 and start building their new Stack Exchange site, not to start the community building process at Area 51. I left a comment there, but I think the matter is worth more elaboration. If I cant start building the community at Area 51, where and how could I create a community that I could bring there There typically is no pre-existing community. And even if there was, its hard to start building a QA community if we first have to get somehow magically organized before we can come to Area 51 and even propose having a QA site. If nothing else, it would be useful to have some hints or suggestions to start building a community and know whether the SE network wants to be a part of that early stage. For example, I am a Finn and I would much like to see a site for Finnish la...

what can go wrong in context of functional programming if my object is mutable? I can see the benefits of mutable vs immutable objects like immutable objects take away lot of hard to troubleshoot issues in multi threaded programming due to shared and writeable state. On the contrary, mutable objects help to deal with identity of object rather than creating new copy every time and thus also improve performance and memory usage especially for larger objects. One thing I am trying to understand is what can go wrong in having mutable objects in context of functional programming. Like one of points told to me is that the result of calling functions in different order is not deterministic. I am looking for real concrete example where it is very apparent what can go wrong using mutable object in function programming. Basically if it is bad, it is bad irrespective of OO or functional programming paradigm, right I believe below my own statement itself answers this question. But still I need...

Bound for the Brownian motion exit time Suppose T inft: B_tnotin a,b where a0b and aneq -b. I would like to show mathbbET2 leq C mathbbEB_T4.

FillChar and StringOfChar under Delphi 10.2 for Win64 Release Target I have a question about a specific programming problem in Delphi 10.2 Pascal programming language. The StringOfChar and FillChar dont work properly under Win64 Release build on CPUs released before year 2012. Expected result of FillChar is just plain sequence of just repeating 8-bit characters in a given memory buffer. Expected result of StringOfChar is the same, but the result is stored inside a string type. But, in fact, when I compile our applications that worked in Delphi prior to 10.2 by the 10.2 version of Delphi, our applications compiled for Win64 stop working properly on CPUs released before year 2012. The StringOfChar and FillChar dont work properly they return a string of different characters, although in a repeating pattern not just a sequence of the same character as they should. Here is the minimal code enough to demonstrate the issue. Please note that the length of the sequence should be at least ...

Unsure about definition of “n” and “C” values in mitosis I am preparing for a Biology exam and Im reviewing the n and C notation used in mitosis. My professor said that when the cell replicates its DNA in S phase of mitosis, we get twice the amount C of DNA, but we still have the same number of chromosomes. Does this mean that if the replicated chromosomes were to split apart from their centromeres, we would have a 4n cell so a cell with 4 sets of chromosomes At the same time, my intuitive response sort of says, well, theyre replicated, so theyre exactly the same, so youd technically have 2 sets, not 4 right. While Ive not heard of the C notation previously, n is common notation that indicates the ploidy of a cell. The n refers to the number of unique chromosomes within a cell. Eukaryotic cells are generally diploid, or 2n. The multiplying number - 2 in the diploid case - refers to the number of versions of each unique chromosome. For example, humans are diploids 2n. We have 23 uniq...

Multiple node network communication over I²C I am working on a project where I want to send data from and to different Arduinos on a network. At the moment IC seems the best option for my needs since I can specify where to send the data. But using this method I have a bit of an issue I cant seem to find a solution for :. I will try to explain my problem using the following image: In the backend all the nodes are connected like in the first image above the example network. But the nodes may be connected in a different sequence by a user. See the example network. In this example network, the node with ID 1 needs to send data to ID 10 and not to any other node on the network. Node ID 12 also needs to send data to node ID 10, but no other nodes. Etc. Etc. Etc. But the node that needs to send data to the next node doesnt know the id of the node it needs to send to. So at first the nodes need to find out what nodes they are connected to and where they need to send their data. I...

Self-destributing token contract template Self-destributing token contract template Hello, Are there any complete templates or resources for making a token which distributes itself when funds are sent to the contract I. e. user sends 0.01 ETH to contract, which in turn sends X tokens back to user.

Identical and different object distribution among children In how many ways can we distribute 12 identical apples and 7 distinguishable cookies among 5 children.. My answer is binom125-112 cdot 57 Is it correct Explanation: Since there is no restriction to distribute the apples, I lined up the 12 apples and split them into 5 groups using the stars method and for the second one, It is only like assigning a cookie to each child. What if it says, 7 distinguishable cookies among 5 children so that everyone gets at least one My answer is: binom75 5 52 We give the kids 5 cookies and they can be arranged in 5 ways, then we normally distribute the remaining cookies. Am I missing anything Are there any notes or something you would like to add up or advice Your solution of first question is perfectly correct. You didnt miss anything. For the second question: Let A_i be the set of all distributions in which i-th children dont get a cookie. Then A_i 47 for each i. A_icap A_j37 for e...

Using grep or awk to print text before and after match, to a specific beginning and ending string I am trying to extract entries from within a large Genbank file, with many thousands of entries. For a search string, Im using a unique gene name - that works fine. The tricky bit is that Id like to print the entire entry for that particular gene - entries begin with the word LOCUS and end with , and contain the gene name at some point between. I understand that I can use greps flags -A, -B, and -C to print n lines afterbefore a string match, but the actual entries are variable in length. How would I use grep to search for my string gene name, and then print all the lines before the match up to and including a line beginning with LOCUS, and all lines up to and including a line indicating the end of the entry, which is just Im open to all suggestions - is there a way to have the -A and -B flags match a strings LOCUS and or something to that effect Should I be using awk instead Edit: Thi...

In one of the many winning scenarios in the Superbowl lottery, a winning pair of tickets is: Concatenation of the two ticket IDs in the pair, in any order, contains each digit from 0 to 9 at least once. For example, if there are 2 distinct tickets with ticket ID 12930455 and 56789, 129300455,56789 is a winning pair. NOTE: The ticket IDs can be concantenated in any order. Digits in the ticket ID can occur in any order. Your task is to find the number of winning pairs of distinct tickets, such that concatenation of their ticket IDs in any order makes for a winning scenario. Complete the function winn...

When are NS records at the apex of a DNS domain queried? Lets say, that I have a following example.com zone: TTL 120 IN SOA ns1 hostmaster 2018041509 300 150 600 60 IN NS ns1 IN NS ns2 ns1 IN A 192.168.0.159 ns2 IN A 192.168.0.160 blah IN A 192.168.0.141 As seen above, ns1.example.com and ns2.example.com are two authoritative name-servers for that zone. When are they queried by other name-servers As much as I tested, the only time when those two records were queried was when I asked for NS records from 192.168.0.159 with a DNS lookup utility, i.e dig 192.168.0.159 -t NS example.com. For the casual user, it really shouldnt matter...

Dipole antennas: Will paracord hold up well enough in the sun? Is there a better alternative? Tower is up and pre-stretched multi-strand 14 Ga wires are cut terminated for a multiband fan-style dipole antenna system. Location is the desert southwest of the USA. Stringing up parts of it are going to be a challenge due to topography, and it will require lengthy tie-down cord on the end of the 7580 Meter portions. Monofilament would definitely stretch and break down in the sun. So Im intending to use paracord and have a quantity of Mil Spec 7 Stranded Type III Nylon black paracord on hand. My question: 1 Will paracord hold up well enough in the hot sun And does the color matter i.e., will black paracord degrade noticeably faster than white 2 Is there a better alternative FYI, I used the same antenna wire mentioned here: HF SWL antenna wire Will plain 16-Gauge copper wire work well enough Paracord is a usurped and abused term for a wide variety of cords. The US Military pre...

Laptop turned in to IT support has a document with staff member's name. Is it ethical for the staff member to read it? Im one of the two team members who work in IT support at my company. I recently had a laptop turned in for hard drive replacement. While copying the files to the new drive, I noticed a document named John Doe.docx, where John Doe is my full name. I returned the laptop after replacing the drive, but have yet to destroy the old drive. Would it be ethical for me to read the document having my name I understand itd generally be considered an integrity violation to read emails and other documents of others. Thats not what Im doing or is it EDIT: I accepted an answer and have wiped the disk without opening anything. As an IT support person, you are only authorized to do what is needed to resolve the users IT issues. In this case, the user wants his disk replaced without losing his data. Hence, you only need to move the data from the old disk to the new disk, and repl...
