            Flutter - How to refresh a Widget on button Click?
            Asked 2022-Mar-01 at 10:15

            I'm making an app where I plot charts of cryptocurrency. I have a file like this, that renders a chart of btc/24h in it. I'm using chart_sparkline package to plot the chart.

            I have the following code, and it is not working on a button click, how do I fix this?



            Answered 2022-Mar-01 at 10:15

            I fixed this, I was passing constructor parameters of Portfolio to _PortfolioState, this won't update the values the next time. Instead of passing these values to _PortfolioState, I used widget.coin and widget.days to extract the data from the Portfolio class.

            You can remove the x title by setting title=None in the x encoding. You can add a line break to the problematic strings by replacing them with a list of lines. For example:

            You don't need anything in root .htaccess for this and just a RewriteCond by itself isn't doing anything anyway.

            Add data into 2 columns in same row with the data coming from Javascipt Websocket
            Asked 2022-Jan-17 at 05:28

            I am new to JavaScript, not sure if this very basic question. I've created a Bitcoin Price update dashboard using the data fetched from the external WebSocket. I managed to get the data from the WebSocket and display it on the HTML table but i was only able to fetch only the live price of the bitcoin I want to also display the Bitcoin quantity in the other column. I want to know how to append two different data in 2 columns in one row. I tried my best to explain.

            I have provided the code snippets below as well as external Websocket from where I am pulling the data.

            NOTE: I'm pulling the data from an external websocket and with that WebSocket I can get all the details like Bitcoin price, quantity, type and everything. "messageObject.p" means Price and "messageObject.q" means Quantity. p=price and q=quantity. I'm able to get the messageObject.q (quantity) to be displayed on the table but I'm unable to show the messageObject.p (price) in the other column of the table.

            Please let me know how should I insert the row dynamically into a HTML table. Thank you so much in advance



            Answered 2022-Jan-09 at 21:26

            You only have one parameter in your insertRow() function. Also, inside of your insertRow() function, you are never trying to read from the passed in quantity variable.

            Answered 2021-Oct-06 at 02:26

            This is actually a warning, not an error, though it may seem like the latter. This means that on your OS and architecture, that particular library does not exist, so it falls back to a different implementation (using a non-native library). In this case, the block verification is slower, but otherwise RSKj should continue to function properly.

            Something that might help you to overcome the “slowness” of the initial sync is the --import flag. See the reference in the CLI docs for RSKj.

            Also you can send an RPC to ensure that your node is running OK. Run the following curl command in your terminal

            Calculating Bitcoin mining difficulty
            Asked 2021-Dec-24 at 09:38

            I am working on a project that requires me to get real time mining difficulty of bitcoin. So I read on this page that explains how to get the mining difficulty from an hash of a block :

            So I made this python script that collect all hashes from the Blockchain api between two dates.( and calculate mining difficulty from the hashes.

            But when I plot the result, I have something really different from every other mining difficulty that I saw online. The mining difficulty is really messy as you can see here :

            x= time , y = difficulty

            Here is when I apply a np.log to the difficulty: x= time , y = np.log(difficulty)

            As you can see, the result is really messy. So I wondered if there is a crypto expert that is able to tell what is wrong with my code of my formula (or maybe if I am right) :)

            Here is my code :



            Answered 2021-Dec-23 at 21:10

            Since the hashes are effectively random, with each bit independent, there is a chance that, in addition to the n required 0s for the proof of work, some following bits are 0 as well. (These hashes would have been valid even if n had been higher at the time, but that’s not relevant.) The “dynamic range” here, relative to the floor of the noise which may be taken as the required difficulty, seems to cover about e10=22000, which is easily appropriate for the number of blocks mined.

            (The actual n isn’t an integer, since the target isn’t a power of 2, but this gives the correct idea.)



            Python - BeautifulSoup - Selecting a 'div' with 'class'-attribute shows every div in the html
            Asked 2021-Dec-01 at 11:34

            I'm trying to crawl with BeautifulSoup (I know there is an API, for training purposes, I want to use BeautifulSoup). Every piece of information crawled so far was pretty easy to select, but now I like to get the "Holder Statistics" looking like this:

            holder stats

            My testing code for selecting the specific div containing the desired information looks like this:



            Answered 2021-Dec-01 at 11:34

            You should use .select() when you want to use as css selector. In this case, holders ='div', class_='n0m7sa-0 kkBhMM') the class part is essentially ignored...and it finds all the

            with any class. To specify that particular class use either the .find_all(), or change your .select()

            holders ='div.n0m7sa-0.kkBhMM')


            holders = soup.find_all('div', class_='n0m7sa-0 kkBhMM')

            Now in both of these cases, it will return None or an empty list. That is because that class attribute is not in the source html. This site is dynamic, so those classes are generated after the initial request. So you either need to use Selenium to render the page first, then pull the html, or see if there's an api to get the data source directly.

            There is an api to get the data:
