| Elixir: Looping through a map, comparing it to itself, and updating it Posted: 06 Apr 2021 08:46 AM PDT I have a map of a billiard ball table, as follows: ball_map = %{ "cue" => {"x":-15.0, "z": 0.0, "velocity_x": 0.0, "velocity_z": 0.0, "is_idle": true}, "ball_1" => {"x":15.0, "z": 0.0, "velocity_x": 0.0, "velocity_z": 0.0, "is_idle": true}, "ball_2" => {"x":17.0, "z": 1.1, "velocity_x": 0.0, "velocity_z": 0.0, "is_idle": true}, "ball_3" => {"x":17.0, "z": -1.1, "velocity_x": 0.0, "velocity_z": 0.0, "is_idle": true} }
I need to apply collisions to it. For that to work properly, each ball must be checked against the others, and the ball locations must be updated as it checks. In my previous attempts, I made a "collision map" and then applied the new locations after, but this had problems with subsequent collisions. So what I'm trying to do is - Loop through each item in the map.
- Compare that item with every other item, and run a check for collision on it (I have a function for that).
- Update both items upon collision, while keeping the format of
ball_map. The code I've come up with for that is this: collision_result = Enum.reduce(result, fn {ball_a, body_a}, acc -> new_result = Enum.map(result, fn {ball_b, body_b} acc -> if (ball_a != ball_b) do has_collided = checkStaticCollisions(body_a, body_b, const_physics["billiard_ball_radius"]) # Takes in parameters (Body A, Body B, radius) # Returns true or false if has_collided == true do calc = PGS.Collision.calculatePosAfterCollision(ball_a, body_a, ball_b, body_b, const_physics["billiard_ball_radius"]) # Takes in parameters (Key of Ball A, Value of Ball A, Key of Ball B, Value of Ball B, radius) # Returns {"id_of_ball_a" => {new X and Z pos}, "id_of_ball_b" => {new X and Z pos}} new_a_pos = calc[ball_a] new_b_pos = calc[ball_b] new_a = %{"x" => new_a_pos["x"], "z" => new_a_pos["z"], "velocity_x" => body_a["velocity_x"], "velocity_z" => body_a["velocity_z"], "is_idle" => body_a["is_idle"]} new_b = %{"x" => new_b_pos["x"], "z" => new_b_pos["z"], "velocity_x" => body_b["velocity_x"], "velocity_z" => body_b["velocity_z"], "is_idle" => body_b["is_idle"]} Map.put(acc, ball_a, new_a) Map.put(acc, ball_a, new_a) else acc end else acc end end) end)
Now this doesn't work, as I'm getting a BadMapError (I assume something to do with the accs on else's), but I'm also positive this will result in a list within a list. I'm still rather new to Elixir, and I'm not sure what else I can do. Is there anything else I can try to make this work? Are there non enum-approaches (does recursion count?)?  |

| VHDL- back and forth seven segment counter Posted: 06 Apr 2021 08:45 AM PDT I'm doing a university assignment where a code was given from an old board and i had to run it on a new one. (Nexys --> Basys3). In one of the tasks, it was necessary to make the seven segment count to 9 (0-1-2-3-4-5-6-7-8-9) and then back to 0 (9-8-7-6-5-4-3-2-1-0). I did this task, but the teacher did not like exacly how it counts. It was something like (0-1-2-3-4-5-6-7-8-9 -> 9-8-7-6-5-4-3-2-1-0-0-1...) but should be (...1-0-1...). And one more task is that with each new digit, the little dot should change it value (0 <--> 1) I honestly do not fully understand the VHDL syntax,. which makes it much more difficult. So my questions are: - At the moment i cannot understand why i have this additional "0" when counting...and how can i fix this ?
- How to make little dot change it's value so it "blinks" ?
Yes, i know that you should simply change the value of correct bit something like...seg(7) <= '1'; but for some reason even this doesn't work...or again i do not fully understand something.

| What algorithm to efficiently traverse all edges in a graph? Posted: 06 Apr 2021 08:46 AM PDT Big Picture I'm writing some code to simulate a computer at the transistor level. The emulator boils down to a graph where each node is a transistor, and each edge is a wire connecting any two transistor nodes on the graph. This graph is cyclic, and transistor nodes may be connected to themselves. To run a single "step" of the emulator, two separate functions are run: - Each wire edge is processed, setting the input of its target node from the output of its source node. Each wire is visited exactly once each step, but a transitor may be visited multiple times.
- Each transistor node output state is updated from its input's states (how is outside the scope of this question, I'm pretty sure I'm doing it efficiently).
I believe I have the second step optimised, but I need help making the first step more efficient. Implementation The code looks roughly like this: type InputBit = usize; type OutputBit = usize; struct Emulator { inputs: Vec<u64>, outputs: Vec<u64>, wires: Vec<(InputBit, OutputBit)>, } impl Emulator { fn step(&mut self) { step_wires(&mut self); step_transistors(&mut self); } fn step_wires(&mut self) { for (input, output) in self.wires.iter() { // NB omitted bit-twiddling to get bit indices self.outputs[output] = self.inputs[input]; } } fn step_transistors(&mut self) { // ... omitted for brevity ... } }
Each transistor node N is composed of two input bits at bit 2N and 2N+1 in self.inputs, and two output bits at 2N and 2N+1 in self.outputs. The problem as I see it, is that my list of wires (and the transistors) is in arbitrary order. This means it's really cache inefficient. For example, imagine this set of wires (input node bit, output node bit): [ (0, 1000), (1000, 2000), (1, 1001), (1001, 2001) ]
If my memory cache size is < 1000 bits, that means I get a cache miss for most of the reads and writes. If they were reorganised into: [ (0, 1000), (1, 1001), (1000, 2000), (1001, 2001) ]
Then it's less cache misses. Equally, I could also "move" the Transitor Nodes to give the following equivalent graph: [ (0, 2), (1, 3), (2, 4), (3, 5) ]
Which now only uses one cache line! Much faster. (Note this example is slightly misleading, as the Node indices will be densely packed, i.e. there wont be any "empty" node indices that are unused. But it is fine to "swap" nodes). Finally, The Question What algorithm can I use to chose which order I visit the Wire Edges, and/or reorder the Transitor Node indices, so that I have the minimum number of cache misses while traversing the graph? I think something that reduces the total "distances" of all the edges would be a good start? And then something that sorts the edges so that ones which are entirely within a single cache line are visited first, in cache line order? And then do between-different-cache-line edges in some order? Any help pointing towards the right things to google much appreciated!  |
| How can I search values of consecutive XML nodes with C#? Posted: 06 Apr 2021 08:45 AM PDT I want to select nodes from an XML that have consecutive child nodes with values matching with the respective words from my search term. Here is a sample XML: <book name="Nature"> <page number="4"> <line ln="10"> <word wn="1">a</word> <word wn="2">white</word> <word wn="3">bobcat</word> <word wn="3">said</word> <line> <line ln="11"> <word wn="1">Hi</word> <word wn="2">there,</word> <word wn="3">Bob.</word> <line> </page>
My search term is Hi Bob. I want find all the nodes from the above XML that contain two consecutive words with values %Hi% and %Bob%. Please note that I want to perform a partial and case-insensitive match for each word in my search term. It should return the following output for the above XML: ln="10" wn="2" wn="3"
Please note that line (ln=10) is selected because it contains two consecutive words (in the correct order) that match with the search term. white=%Hi% bobcat=%Bob% However, the next line (ln=11) is not selected because the matching nodes are not consecutive. Please note that all the words from the search term should be matched in order for it to be considered a match. Thank you!  |
| TypeError with scatterplot and label Posted: 06 Apr 2021 08:45 AM PDT This seems pretty simple, but for some reason, I can't get it to work. This is in pandas 1.2.3 and matplotlib 3.4.0 running on an anaconda's python 3.8.8 on Windows 10 64-bit, inside a Jupyter notebook locally. I've created a replication below. First, a working version; note the commented out label line: import numpy as np import pandas as pd import matplotlib.pyplot as plt df_test = pd.DataFrame(np.random.randn(1000, 4), columns=list("ABCD")) df_test.plot(kind="scatter", x="A", y="B", alpha=0.4, figsize=(10,7), #label="la la", s=df_test["C"]*100, c="D", cmap=plt.get_cmap("jet"), colorbar=True, ) plt.legend()
Running the above gives a complaint No handles with labels found to put in legend (as expected) and some deprecation warnings, but shows a chart. The dots are nicely colored, and you might even see the empty legend box.

It seems to be an interaction with the c= for the coloring and the label=. If I comment out the color stuff (c=, cmap, colorbar), the plot renders with a legend box, and we saw that it also works with colors included and label commented out. I also tried restarting the kernel, and had same results. I have not tried making new environments with other versions yet, as I wanted to see if this was just me, or something others could replicate. (BTW, On Colab, python 3.7.10, pandas 1.1.5, matplotlib 3.2.2, the code does appear to work (with a minor figsize complaint), so could be something about the more recent versions of these packages, or my setup...) So, please be kind, but could anyone point out what silly thing I'm missing here? Any suggestions? Anyone able to replicate?  |
| How to dynamically select elements with document.querySelectorAll() for function call? Posted: 06 Apr 2021 08:45 AM PDT I have been working on this fiddle: https://jsfiddle.net/j1vrb7to/165/ The code in that fiddle is this: HTML: <div id="CalculationContainer"> <input type="numbers" class="form-control new-tuition" /> <br /> <input type="numbers" class="form-control new-tuition" /> <br /> <input type="numbers" class="form-control new-tuition" /><br /><br /> <input type="numbers" id="new-tuition-total" disabled="disabled" /><br /> <br /> <input type="numbers" class="form-control new-state" /> <br /> <input type="numbers" class="form-control new-state" /> <br /> <input type="numbers" class="form-control new-state" /><br /><br /> <input type="numbers" id="new-state-total" disabled="disabled" /> </div>
JavaScript: const NewTuitionInputs = document.querySelectorAll("div#CalculationContainer > input.new-tuition"); const NewStateInputs = document.querySelectorAll("div#CalculationContainer > input.new-state"); NewTuitionInputs.forEach(function(input) { input.onchange = function() { var total = 0; NewTuitionInputs.forEach(function(input) { total += parseInt(input.value); }); document.getElementById("new-tuition-total").value = total; } }); NewStateInputs.forEach(function(input) { input.onchange = function() { var total = 0; NewStateInputs.forEach(function(input) { total += parseInt(input.value); }); document.getElementById("new-state-total").value = total; } });
As the users enter values into the textboxes, I want to update the value of another field to display running totals. Ultimately I will need to keep track of 20+ running totals on my form. Instead of maintaining 20+ functions, is it possible to use a single function to calculate running totals on the fly? Here is some pseudocode to demonstrate what I'm thinking: var ThisInput = document.querySelectorAll("div#CalculationContainer > input.[INPUT_CLASS_PARAMETER_HERE]"); ThisInput.forEach(function(input) { input.onchange = function() { var total = 0; ThisInput.forEach(function(input) { total += parseInt(input.value); }); document.getElementById("[DYNAMICALLY_CHOOSE_WHERE_TO_DISPLAY").value = total; } });

| Getting the error: bash: (program): cannot execute binary file: Exec format error, on both 32-bit and 64-bit Windows Posted: 06 Apr 2021 08:45 AM PDT There is a program developed for linguistic research (http://people.csail.mit.edu/mcollins/code.html). When I try to run the parser using Git bash terminal on Windows, I get the error: bash: cannot execute binary file: Exec format error.

| How to run a script from a package from the command line Posted: 06 Apr 2021 08:45 AM PDT I have trouble running a Python module from a package as a script from the command line. I have a Python package located at /path/to/pkg with a structure that goes something like this: pkg subpkg1 __init__.py module1.py subpkg2 __init__.py module2.py __init__.py
The content of module2.py is something like: from subpkg1 import module1 if __name__ == '__main__': module1.foo()
I want to be able to run module2.py from the command line regardless of the current working directory, but I can't get it to work. These are the various alternatives I've tried: python /path/to/pkg/subpkg2/module2.py. This results in the error ImportError: No module named subpkg1python -m /path/to/pkg/subpkg2/module2. This results in the same error as above, ImportError: No module named subpkg1python -m /path/to/pkg.subpkg2.module2. This results in the output /usr/bin/python: Import by filename is not supported.. I don't even understand what this message is supposed to tell me.python -m pkg.subpkg2.module2. This results in the output /usr/bin/python: No module named subpkg2. I'm like: Of course there is no module named subpkg2, because it's a package, not a module. But weirdly, Python was apparently able to locate pkg without me providing a path to it? I'm confused. What am I doing wrong? Note that I have not appended /path/to to the PYTHONPATH and if possible, I'd like to avoid doing so. I just want Python to be aware of the fact that module2.py is located inside a package rather than just being an isolated script, so that the absolute import from subpkg1 import module1 can be resolved. Note also that I'm on Python 2.7 in case it makes any difference.  |

| Loop through multiple rows as labels and data in chart.js and PHP Posted: 06 Apr 2021 08:46 AM PDT Using chart.js I want to create a graph of a given stock price. The labels and data are fetched using the data from $select_query. Here I create a dynamic function that gets the ticker name from the URL: https://signal-invest.com/tick/?ticker=LOW $select_query = $con->prepare("SELECT Date_buy, Name_buy, Price_buy FROM daily_buy_orders WHERE Name_buy = ?"); $select_query->bind_param('s', $ticker); // 's' specifies the variable type => 'string' $select_query->execute();
I tried to loop through the rows using the while loop but failed. <canvas id="myChart" style="border: 1px solid black; margin: 25px 25px" height="300"></canvas> <script> var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'line', data: { //labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'], labels: [<?php $get_dates = $select_query->get_result(); while ($rows = mysqli_fetch_assoc($get_dates)) { $dates = $rows["Date_buy"]; echo ''.$dates.''; } ?>], datasets: [{ label: '# of Votes', //data: [12, 19, 3, 5, 2, 3], data: [<?php $get_prices = $select_query->get_result(); while ($rowss = mysqli_fetch_assoc($get_prices)) { $prices = $rowss["Price_buy"]; echo ''.$prices.''; } ?>], backgroundColor: 'rgba(255, 99, 132, 0.2)', borderColor: 'rgb(75, 192, 192)', borderWidth: 1 }] }, options: { scales: { y: { beginAtZero: true } } } }); </script>
Above code messes with my table below. When creating the tables the while loop actually works. I tried to use the same thinking when doing the while loops for the labels and data in chartjs, didn't work though. <table style="width:50%" border="solid"> <tr> <th>Name</th> <th>Price</th> <th>Date of signal</th> </tr> <?php $result = $select_query->get_result(); while ($row = mysqli_fetch_assoc($result)) { $name_buy = $row["Name_buy"]; $price_buy = $row["Price_buy"]; $date = $row["Date_buy"]; echo buy_table($name_buy, $price_buy, $date); } ?> </table>

| Glomming to make a sh script Posted: 06 Apr 2021 08:46 AM PDT Is this a stupid thing to do? - pipe output of ls -1 to a file
- edit the file to surround each line with quote characters
- and add a command at front of each line
- make the file executable
- run it as a script
I ask because the files swept up in ls -1 have special characters like parentheses, back quotes, etc. My editor macro surrounds each filename with double-quotes, but that's not enough. Is there a more righteous way to do this? Should I be glomming within the script itself? I like using the editing step to catch errors, but I may just be being stubborn, (Context: I have thousands of MP3 files and want to run a program on each to get its tempo.) What's the smart thing to do here?  |

| How to change revision format in Google Code? Posted: 06 Apr 2021 08:46 AM PDT I'm REALLY new to DVCS and am trying out Mercurial with Google Code as I'd like to share some extensions that I recently wrote for Google Chrome. I notice that in Google Code, most projects seem to refer to changesets via sequential numbers (eg. 1, 2, 3, etc. -- (see screenshot #1 below)). My test project (screenshot #2), however, uses the hex values and I don't see anything in project settings to change this. How do I get it to display using the aforementioned linear format?
Also, being new to social coding, it seems that everywhere else on the internet, your email address is a private thing but these DVC systems seem to want your email to associate with commits (and Google, github, etc. seem intent on displaying them). Is there some sort of etiquette here? It seems that most people on Google Code edit their config file to only show the username with no real name or email information for associated commits.
