I have the following code snippet (a gist can be found here) where I am trying to do a sum between 4 int32_t negative values and 4 int16_t values (that will be sign extend to int32_t). extern exit global _start section .data a: dd -76, -84, -84, -132 b: dw 406, 406, 406, 406 section… Read More sse4 packed sum between int32_t and int16_t (sign extend to int32_t)
Tables and code at the bottom will probs help much more than description. I have a solution that works but think its very inefficient see bottom. Problem: I have two data frames df_1 and df_2 — these dataframes have a match column – match_id df_2 has a date column that I am trying to write… Read More Python: Filling a dataframe sequentially based on matching ids (inefficient code)

As far as I understand .NET concepts, the source code is first translated into an Assembly (IL code+meta data), which is compiled to machine code on the target machine with the CLR’s JIT compiler. However I cannot really match these concepts to what I see when working on a C# project. When I build a… Read More Understanding .NET compilation
I’m making a program to add items to a LIFO (last in first out) array, where the elements are inserted at the start of the array. Here is my code: typedef struct neud{ int num; struct neud *next; }neud; void add(neud** head,int val){ //creat a new neod neud* newNeod; newNeod = malloc(sizeof(neud)); //assigning newNeod->num =… Read More I'm having a problem understanding double pointers

I am combining several spreadsheets with identical layouts into one master, and want to create a way to have my query({importrange}) be dynamic, as I will be adding / removing some sheets as time goes on. I have all of my sheet addresses in column C, so my formula right now looks like: =QUERY({Importrange(C4,Sheet1!C5:F);Importrange(C5,Sheet1!C5:F);…} This… Read More Expandable Importrange
