QUESTION
Hey guys given the example below in C when operating on a 64bit system as i understand, a pointer is 8 byte. Wouldn't the calloc here allocate too little memory as it takes the sizeof(int) which is 4 bytes? Thing is, this still works. Does it overwrite the memory? Would love some clarity on this.
Bonus question: if i remove the type casting (int*) i sometimes get a warning "invalid conversion from 'void*' to 'int*', does this mean it still works considering the warning?
...ANSWER

is allocating the amount of memory you asked for on the heap. The pointer is allocated by your compiler either in registers or on the stack. In this case, calloc
is actually allocating enough memory for 4 int
s on the heap (which on most systems is going to be 16 bytes, but for the arduino uno it would be 8 because the sizeof(int)
is 2), then storing the pointer to that allocated memory in your register/stack location.
For the bonus question: Arduino uses C++ instead of C, and that means that it uses C++'s stronger type system. void *
and int *
are different types, so it's complaining. You should cast the return value of malloc
when using C++.

I'm trying to get a bootstrap datepicker to work to update layer dates in my website. However, the problem that I am getting at the moment is that when I click on the datepicker box, the calendar dropdown isn't working at all and it just continues to display an empty box.
I'm trying to add the datepicker inside a Leaflet textbox control and add the HTML directly into an .innerHTML method. Below is the code for the Leaflet textbox control and the datepicker itself.

Answered 2021-Jun-15 at 08:12The fix to this seemed to be to wrap the datepicker in a $(document).ready(function() { })
type function.
So the full datepicker function from above becomes:

How to create BottomNavigation with one of the item is larger than the parent, but without using floatingActionButton. For example like this:
I tried to do that by wrapping the icon with Box but it get cut like this:
Then i try to separate that one button and use constraintLayout to position it, but the constraintLayout cover the screen like this. Even when i color it using Color.Transparent, it always feels like Color.White (i dont know why Color.Transparent never work for me). In this picture i give it Red color for clarity reason.
So how to do this kind of bottomNavBar without having to create heavy-custom-composable?
Update: so i try to make the code based on MARSK and Dharman comment (thanks btw). This is what i
...ANSWER
Answered 2021-Jun-13 at 21:06Custom Composable are not heavy, really.
Anyway, try this:-
Create a Container of MaxWidth (maybe a BoxWithConstraints or something), keep its background transparent, set the height to wrap content. Create the tabs as usual, but keeping the bigger tab's icon size bigger explicitly using Modifier.size(Bigger Size).
After you have this setup, add another container inside this container with white background, covering a specific height of the original container. Let's say 60%
Now set the z-index of all the icons and tabs to higher than the z-index of this lastly added container. Use Modifier.zIndex for this. And viola, you have your Composable ready.
In order to set a specific percentage height of the inner container, you will need access to the height of the original container. Use BoxWithConstraints for that, or just implement a simple custom Layout

QUESTION
I'm looking into using QuestDB for a large amount of financial trade data.
I have read and understood https://questdb.io/docs/guides/importing-data but my case is slightly different.
- I have trade data for multiple instruments.
- For each instrument, the microsecond-timestamped data spans several years.
- The data for each instrument is in a separate CSV file.
My main use case is to query for globally time-ordered sequences of trades for arbitrary subsets of instruments. For clarity, the results of a query would look like
...ANSWER
Answered 2021-Jun-13 at 22:11As of 6.0 you can simply append the CSVs to same table one by one given the table has designated timestamp and partitioned it will work.
If your CSVs are huge I think batching them in transactions with few million rows will be better than offloading billions at once.
Depending of how much data you have and your box memory you need to partition in a way that single partition fits memory several times. So you choose if you want daily or monthly partitions.
Once you decide with partitioning you can speed up the upload if you able to upload day by day batches (or month by month) from all CSVs.
You will not need to rebuild the table every time you add an instrument, table will be rewritten automatically partition by partition when you insert records out of order.

Investment value is Row 2 * Row 3
.
This value is carried across all the months after amortization given in row 4. 5th row is converting the yearly value into monthly value (1/12).
So, in the first month 50 is invested and the value at the beginning of the month after amort of 100%, So 50 is available for month 1. This is further converted into monthly values with the help of row 5. So, the result for month 1 will be 100 * 50% * 100% * 8.33%
= 4.1667
[Cell I9]
For the month 2, the value available is,
Value carried from month 1 after amort (100 * 50% * 99%)
+
New amount in month 2 (102 * 50% * 100%)
The above value is converted into the monthly value again with the help of row 5.
Result for month 2 => Cell I10 = (100 * 50% * 99% * 8.33%) + (102 * 50% * 100% * 8.33%)
= 8.375
Similarly, for month 3 the value will be,
Month 1's investment (100*50%*98%*8.33%)
+
Month 2's investment (102*50%*99%*8.33%)
+
Month 3's investment (104*50%*100%*8.33%)
I need the above calculation to happen in single cell for all the months. I tried sumproduct with offset. But I couldn't.

QUESTION
I have a dataframe containing two columns: one filled with a string (irrelevant), and the other one is (a reference to) a dataframe.
Now I want to only keep the rows, where the dataframes in the second column have entries aka len(df.index) > 0
(there should be rows left, I don't care about columns).
I know that sorting out rows like this works perfectly fine for me if I use it in a list comprehension and can do it on every entry by its own, like in the following example:
ANSWER
Answered 2021-Jun-12 at 15:07Not sure if I understand your question or where you are stuck. however, I will just write my comment in this answer so that I can easily edit the post.
First, let's try typing in myvar = df['Percentage'] > 80
and see what myvar
is. See if the content of myvar
makes sense to you.
There is really only 1 true rule of .loc[]
, that is, the TRUTH TABLE.
Regarding the df[stuff] expression
always appears within .loc[ df[stuff] expression ]
, you might get the impression that df[stuff] expression
had some special meaning. For example: df[df['Percentage'] > 80]
is asking for any Percentage
that is greater than 80, looks quite intuitive! so...df['Percentage'] > 80
must be a "special syntax"? In reality, df['Percentage'] > 80
isn't anything special, it is just another truth table. df[stuff] expression
will always be a truth table, that's it.
QUESTION
My data is already sorted by groups based on one column. And within each group I am trying to reorder the values in another column. The below example illustrates what I mean:
Currently my data looks like this, its sorted by the carrier name. The 3rd column shows what type of products they're holding. However, I would like chicken to be first on the list for every carrier, so that it looks like the second table below.
Name Amount Product Carrier A 1 Apples Carrier A 9 Oranges Carrier A 8 Bananas Carrier A 10 Chicken Carrier A 28 Total Carrier B 9 Apples Carrier B 4 Oranges Carrier B 6 Bananas Carrier B 9 Chicken Carrier B 28 Total Carrier C 5 Apples Carrier C 8 Oranges Carrier C 9 Bananas Carrier C 10 Chicken Carrier C 32 TotalThe below table is what I am trying to achieve.
Name Amount Product Carrier A 10 Chicken Carrier A 1 Apples Carrier A 9 Oranges Carrier A 8 Bananas Carrier A 18 Total Carrier B 9 Chicken Carrier B 9 Apples Carrier B 4 Oranges Carrier B 6 Bananas Carrier B 19 Total Carrier C 10 Chicken Carrier C 5 Apples Carrier C 8 Oranges Carrier C 9 Bananas Carrier C 22 TotalIs there a way to do this with pandas? Instinctively I looked at feeding df.sort_value both the Name and Product columns, but realized that it can only sort by ascending and descending order.
Also the order of values in the "Name" column must be preserved for my task. In this example, its already ordered alphabetically, but its not necessarily the case nor my intention in my actual dataset.
Any insight would be appreciated!
