I am writing a simple function to query my database with Knex in Node. Everything I've tried returns Promise { <pending> } Function to query the DB: const queryTable = async () => { const data = await knex .select("*") .from(TABLE_NAME) return data; }; I've tried calling the function in it's own async/await wrapper, and I've tried the .then() callback after... No luck. Any leads appreciated!

i am trying to make a node named "gear" change textures when it moves through a certain area but nothing happens, i tried making it print something when it collides with something, but nothing happens, this problem has been bugging me for days and i cant find any reason why, its hitbox is working but the function refuses to acknowledge it the captialisation is alright i literally copied and pasted it to no avail, i looked at somone elses code other than the name of that node the function is exactly the same, what is going on, link to project

Table headings through the table are being converted into single column headings. url = "https://www.environment.nsw.gov.au/topics/animals-and-plants/threatened-species/programs-legislation-and-framework/nsw-koala-strategy/local-government-resources-for-koala-conservation/north-coast-koala-management-area#:~:text=The%20North%20Coast%20Koala%20Management,Valley%2C%20Clarence%20Valley%20and%20Taree." dfs = pd.read_html(url) df = dfs[0] df.head() Be great if I could have the High preferred use as a column that assigns to the correct species.

I have lots of data we want to store in Snowflake cloud but we could save the data into the snowflake due to date like 31-12-2014 which is given in an excel CSV file: ] I am trying: "Shipment date" varchar(16777216), "Shipment year" number(4), which data type will be suitable for that purpose?

I'm new to shaders, and I'm trying to make an outline of a tk2d spine object(a 2d character). I know there are other ways to obtain the outline effect, but this approach got me curious. (Please don't suggest another way to draw outlines, respectfully, because that is not my question.) So basically how I'm trying to get the outline effect is by getting the vertexes of my object, input a color, and draw it 8 directions(top, down, left, right, 4 diagonal directions) by setting offsets to each direction. I got this working, and it looks fine, but my shader code doesn't, because I have a total of 9 passes, 8 of which do the exact same thing(draw the same texture), with the only difference being the offset direction, and the last pass drawing the tk2d spine character. I don't like that I have 8 almost-exactly repeated codes, it seems to be a waste because there is an area where the same calculation is done 8 times, and I suppose performance would be affected as well...

I am trying to use elasticache redis cluster and using a password with it. When I try to write or read I am seeing. I am running out of ideas of things to try. I have tried to use password in the root node on the object and putting directly. I've tried other libraries and am seeing the same issues. [ErrorReply: NOAUTH Authentication required.] So here is the example of my code sorry for the mess. const redis = require('redis'); const { createCluster, } = redis; const password = 'abc123'; function getRedisClient() { const rootNodes = [{ url: `rediss://:${password}@${host}:6379`, rejectUnauthorized: true, }]; return createCluster({ rootNodes, defaults: { socket: { connectTimeout: 5000, }, }, }); } const cluster = getRedisClient(); cluster.on('error', (err) => console.log('Redis Cluster Error', err)); const run = async () => { try { ...

I am trying to moving some specific cells to a designated location. As shown in the image, would like to move data in cells D3 to E2, D5 to E4,..... so on so for. Is it doable with openpyxl? Any suggestions would be greatly appreciate it!! Click to see the image Here is what I got so far. It worked per say. wb=xl.load_workbook(datafile) ws=wb['Sheet1'] #insert a new column #5 ws.insert_cols(idx=5,amount=1) wb.save(datafile) mr=ws.max_row #move cells for i in range (1,mr+1): v=ws.cell(row = i+1,column=4) ws.cell(row=i,column =5).value=v.value wb.save(datafile) wb.close How do I skip a row? I only wanted to copy values in every other row over.

How would I create a document that has two sections where the headers are different but the footers are the same? For example, I would have the first section be labeled "Header 1" and the second section be labeled "Header 2" but the footer for both of those sections would be the same, in this case, "Author: John Apples." I am working in MS Excel since I want to import some data from a sheet. NOTE: I am very new to VBA I tried using the "DifferentHeaderFirstPageHeaderFooter = True" but that applies to both the header and footer, not just the header. Also, I don't believe I am creating separate sections so it would be nice to have that feature implemented since I plan to add more sections that would have different headers. Any help would be greatly appreciated.

https://i.stack.imgur.com/J0yZw.png This is how it looks for all files with .ts . And in .tsx files it also doesn't work. Other projects in WebStorm work correct but they're written in .js and .jsx only. Also I've tried reinstall WebStorm twice and set all to defaults, that doesn't help at all.

I'm coming from Java, and wanting to use the constructor of a child class the way that it works in Java, but it appears that it doesn't work like that in PHP. The constructor of the child object can't seem to overwrite the instance variable values constructed in the parent object. Here, the parent object is being used just for the common methods between multiple child classes that will extend it. The parent class will never be called on its own. When I instantiate a new TestPackage, I just get the initialized error values from the parent class. What gives? <?php interface Package{ public function getCode(); public function decode($packageCode); public function getSetName(); public function getSetNameLang(); public function getSubsetType(); public function getSubsetTypeLang(); public function setSubsetType($typeCode); public function getPackageOptionsArray(); public function getChoicesArray(); public function getOptionStatus($inde...

for some reason a column in my Material-UI DataGruid wont update upon state change? Code for state var: const [brandMap, setBrandMap] = useState(new Map()); fetchBrands function (which changes state) async function fetchBrands() { const accessToken = await getToken(); await fetch("http://localhost:8000/auth/brands", { method: "GET", headers: { Authorization: `Bearer ${accessToken}` } }) .then((data) => data.json()) .then(data => { setBrandMap(prevState => ({ ...prevState, ...data.data.reduce((map, obj) => (map[obj.id] = obj.name, map), {}) })) }) }; Columns list that I pass into MUI DataGrid, note the "FetchData(1)" function gets the data that the columns use. useEffect(() => { setColumns(({ columns: [ { field: 'image', headerName: '', filterable: false, renderCell: (params) => ( <img src={params.value} style=/> )}, { f...

I'm trying to create a fake website for a school project. So far I've added a banner of images that cross fade. The next thing I want to add is a bar where you could go to different pages like "food," "sale," and so on. I want this bar to go beneath the image banner. When I add the tags though, they are positioned on top of my banner. Before, I had used a simple image banner, and when I added the tags they positioned themselves beneath the image like normal. But because I'm using multiple images and animations, it's behaving differently and I don't know how to fix it. Below is the effect that I want (but it's because I disabled the cross fade) The closest solution I got is changing .fadein{height:1000px} and that moves the buttons down but I'm not sure how viable that is. I've also changed the position of the buttons from relative, absolute, etc. but none give the effect that I want. Here is my code. Edit: I don't know why y...

The first parameter is a dictionary representing data for a city and the second parameter is a data file that is open for reading. This function should modify the dictionary so that it contains the data in the file. If a city with data in the file is already in the dictionary then its data should be updated. Otherwise it should be added to the dictionary with its data. After this function is called, the dictionary should contain key/value pairs whose keys are the names of every city in the data file, and whose values are dictionaries which contain at least the population and economics_situation for those cities. I'm just trying to figure how to even start with this? Can anybody give me a clue, or a first step on an approach? We want our dict to look something like this: This is assuming if its an empty dictionary ''' {'Brampton': {'#': 1, 'population': [703, 38907, 6789, 8769, 9087, 9087]}, 'Pickering': {'#': 2, 'popula...

In the code below when I return a class object in the function getServerSideProps through props, in the page function the variable is undefined, just like in the code below. export default function cars(obj){ return <h1>counter: {obj.counter}</h1> // obj is undefined, why?? } export async function getServerSideProps({req,res}){ class Counter{ constructor(){ this.counter = 22 } } var counter = new Counter() return { props: { obj:JSON.stringify(counter) } } } I was expecting that the page parameter obj would have the object counter and not be undefined.

I'm trying to resolve a file path in NextJS . I understand that API routes are working a little bit differently when deployed to Vercel. In order to create a correct path to the file I assumed I had to do this: const svg = fs.readFileSync( path.join(process.cwd(), "img", "file.svg"), "utf-8", ); // ENOENT: no such file or directory But I cannot make it work. The file cannot be found under that path. How can I find the correct path for a file in NextJS api routes? I've followed the documentation of this. Next version is: 11.1.3 When logging the path, it is giving /var/task/data/project-root/img/file.svg

I have a 3d scatter plot that I created with Plotly in R - is there anyway to move the axes to the middle? My plot right now looks similar to this plot that I made real quick in R: But I would like to remove the grid background, the axis ticks, and move the axes to the middle of the plot to make it look similar to this: My main problem is moving the axes to the middle while maintaining the x, y, and z labels on them. I have used traces to simulate the central axes, but then I have the issue of no axis labels when I remove the background grid and axes. What is the best way to go about this? The code to recreate the first plot is below as well: coords = list("x"=c(), "y"=c(), "z"=c()) for(phi in seq(0, 2*pi, 0.2)) { for(theta in seq(0, pi, 0.2)) { x = (8 * sin(theta) * cos(phi)) y = (8 * sin(theta) * sin(phi)) z = (8 * cos(theta)) coords$x = append(coords$x, x) coords$y = append(coords$y, y) coords$z = append(coords$z, z) } ...

If we reconstruct a protein from a PDB file, is it enough to have a PDB file, or do we need more info external to the PDB? Take, for example, the BioPython framework. If any info is needed external to the PDB files, where does this framework store them? Can I open and check to see those files?

I have an image dataset that is quite imbalanced, with one class having 2873 images and another having only 115. The rest of the classes have ~250 images each. For reducing the imbalance, I decided to split the dataset into Train-Valid-Test components, with the major class having less proportion of images in the training set compared to the minor classes. Then I'll be augmenting the data in the training set. I intend to perform an 80-10-10 split on the dataset. Which outcome shall be considered as an 80-10-10 split? Splitting the dataset in the proportion 80-10-10, and THEN augmenting the training images (which would eventually result in >80% proportion for the training set after augmentation). Splitting the dataset in a proportion such that it eventually results in an 80-10-10 split AFTER augmentation. Also, is it acceptable to have an 85-7.5-7.5 split, provided it reduces imbalance in the dataset?

At least with macros, C compilers are expected to remove at least most constant math operations. For example, func((4 + 40) * 2) is expected to become func(88) during compilation. I don't know what happens with something like this: if (1) first(); else second(); (which is the same as) const int mybool = 1; if (mybool) first(); else second(); Does this just become first(); on most compilers? What about: while(0){ dostuff(); } Does this get removed? If the answer isn't just "They all stay", where is a list of the things C compilers are expected to find and remove (aside from optimization)?

In the Tetris clone I'm making, I'm only working with single blocks right now and I have been trying to stack blocks in a few rows. Here is the code for the blocks if (this.active == false){ this.cube = Math.floor((Math.random()* 7)); this.testblock = this.physics.add.sprite(608, 32, this.blocks[this.cube]); this.testblock.body.immovable = true; this.testblock.body.allowGravity = false; //this.testblock.body.setGravityY(-100); this.physics.add.collider(this.walls, this.testblock); this.physics.add.collider(this.p1, this.testblock); this.activeBlock = this.testblock; this.active = true; } this.activeBlock.y = this.activeBlock.y + 0.5; if(Phaser.Input.Keyboard.JustDown(this.keyE)){ console.log(this.activeBlock.y); } if(Phaser.Input.Keyboard.JustDown(this.keyA) && this.activeBlock.x != 352) { this.activeBlock.x = this.activeBlock.x - 64; } if(Phaser.Input.Keyboard.JustDown(this.keyD) && this.activeBlock.x != 928) { ...
