QUESTION
I have run many times github actions on my repo without problem and with the same script on one of my repo it is displaying “no status”. The repo is: https://github.com/aurelpere/python-planif I dont understand why it is not displaying a status as the workflow runs correctly… Any help would be great thank you
notice my svg badge also shows "no status" at https://github.com/aurelpere/python-planif/workflows/CI/badge.svg and at https://github.com/aurelpere/python-planif/workflows/Unittests/badge.svg . (following what is in this post : https://github.community/t/badge-shows-no-status-and-no-status-mismatch-between-the-filepath-vs-name-usage/16907 or in this post Github Actions badge shows "No status")
I also tried to duplicate the code in another fresh repo (https://github.com/aurelpere/python-geothermal---power-to-gas/ ) and it is the same, the badge shows no status, so it has nothing to do with the fast forward merge issue from here https://github.community/t/workflow-badge-no-status/17280/2
Edit : solved with the answer below, but i deleted the initial repo and kept only the fresh one if you try to follow the links

QUESTION
I am trying to save gas by optimize code. In a flash, however, I was wondered what is the best practice of copying from array to array in Solidity.
I present two option. One is copying by pointer (I guess) and the other is using for-loop.
TestOne.sol
...ANSWER
Answered 2022-Apr-10 at 21:23The best practice is copy array from memory to storage without looping over their items. However contract optimization in this example is tricky. The official documentation says as follow:
If you want the initial contract deployment to be cheaper and the later function executions to be more expensive, set it to
--optimize-runs=1. If you expect many transactions and do not care for higher deployment cost and output size, set--optimize-runsto a high number.
To illustrate above, consider following contracts:
QUESTION
I am in need of help proving that an algorithm has greedy choice property and optimal substructure.
Context of the problem:
Consider a problem where a company owns n gas stations that are connected by a highway.
Each gas station has a limited supply g_i of gas-cans. Since the company don't know which gas station is most visited they want all of them to have the same amount of gas.
So they hire a fueling-truck to haul gas between the stations in their truck. However, truck also consumes 1 gas-can per kilometer driven.
Your task will be to help the chain calculate the largest amount of gas-cans g_bar
they can have at all Stations.
Consider the example: Here we have g = (20, 40, 80, 10, 20) and
p = (0, 5, 13, 33, 36) (in kilometers). In order to send one gas-can from station 3 to
station 4 we need to put 41 gas-cans in the truck, as the fueling-truck will consume 40 before reaching their destination (to send two gas-cans we need to put 42 in the truck).
The optimal g_bar for the example is 21 and can be achieved as follows:
Station 2 sends 11 gas-cans towards Station 1. One gas-can arrives while ten are consumed on the way.
Station 3 sends 59 gas-cans towards Station 4. 19 arrive while 40 are consumed on the way.
Station 4 now has 29 gas-cans and send eight towards Station 5. Two of these arrive and six are consumed on the way.
The final distribution of gas-cans is: (21, 29, 21, 21, 22).
Given an integer g_bar. Determine whether it is possible to get at least g_bar gas-cans in every Gas Station.
in order for the greedy choice property and optimal substructure to make sense for a decision problem, you can define an optimal solution to be a solution with at least g_bar gas-cans in every gas station if such a solution exists; otherwise, any solution is an optimal solution.
Input: The position p_i and gas-can supply g_i of each bar. Here g_i is the supply for the bar at position p_i. You may assume that the positions are in sorted order – i.e. p_1 < p_2 < . . . < p_n.
Output: The largest amount g_bar, such that each gas-station can have a gas-can supply of at least g_bar after the truck have transferred gas-cans between the stations.
How can i prove Greedy Choice and Optimal Substructure for this?
...ANSWER
Answered 2022-Mar-20 at 06:03Let's define an optimal solution: Each station has at least X gas cans in each station (X = g_bar).
Proving greedy property
Let us assume our solution is sub-optimal. There must exist a station i such that gas[i] < X. Based on our algorithm, we borrow X - gas[i] from station i+1 (which is a valid move, since we had already found a solution). Now station i has gas = X. This contradicts the original assumption that there must exist a station i such that gas[i] < X, which means our solution isn't suboptimal. Hence, we prove the optimality.
Proving optimal substructure
Assume we have a subset of the stations of size N', and our solution is suboptimal. Again, if the solution is suboptimal, there must exist a station i such that gas[i] < X. You can use the greedy proof again to prove that our solution isn't suboptimal. Since we have optimal solution for each arbitrary subset, we prove that we have optimal substructure.
QUESTION
I am writing a C interface for CPU's cpuid instruction. I'm just doing this as kind of an exercise: I don't want to use compiler-depended headers such as cpuid.h for GCC or intrin.h for MSVC. Also, I'm aware that using C inline assembly would be a better choice, since it avoids thinking about calling conventions (see this implementation): I'd just have to think about different compiler's syntaxes. However I'd like to start practicing a bit with integrating assembly and C.
Given that I now have to write a different assembly implementation for each major assembler (I was thinking of GAS, MASM and NASM) and for each of them both for x86-64 and x86, how should I handle the fact that different machines and C compilers may use different calling conventions?
...ANSWER
Answered 2022-Mar-11 at 03:23If you really want to write, as just an exercise, an assembly function that "conforms" to all the common calling conventions for x86_64 (I know only the Windows one and the System V one), without relying on attributes or compiler flags to force the calling convention, let's take a look at what's common.
The Windows GPR passing order is rcx, rdx, r8, r9. The System V passing order is rdi, rsi, rdx, rcx, r8, r9. In both cases, rax holds the return value if it fits and is a piece of POD. Technically speaking, you can get away with a "polyglot" called function if it (0) saves the union of what each ABI considers non-volatile, and (1) returns something that can fit in a single register, and (2) takes no more than 2 GPR arguments, because overlap would happen past that. To be absolutely generic, you could make it take a single pointer to some structure that would hold whatever arbitrary return data you want.
So now our arguments will come through either rcx and rdx or rdi and rsi. How do you tell which will contain the arguments? I'm actually not sure of a good way. Maybe what you could do instead is have a wrapper that puts the arguments in the right spot, and have your actual function take "padding" arguments, so that your arguments always land in rcx and rdx. You could technically expand to r8 and r9 this way.

I am trying to deploy my SimpleStorage.sol contract to a ganache local chain by making a transaction using python. It seems to have trouble connecting to the chain.
...ANSWER
Answered 2022-Jan-17 at 18:17Had this issue myself, apparently it's some sort of Ganache CLI error but the simplest fix I could find was to change the network id in Ganache through settings>server to 1337. It restarts the session so you'd then need to change the address and private key variable.

QUESTION
I've been putting together my own disassembler for Sega Mega Drive ROMs, basing my initial work on the MOTOROLA M68000 FAMILY Programmer’s Reference Manual. Having disassembled a considerable chunk of the ROM, I've attempted to reassemble this disassembled output, using VASM as it can accept the Motorola assembly syntax, using its mot syntax module.
Now, for the vast majority of the reassembly, this has worked well, however there is one wrinkle with operations that have effective addresses defined by the "Program Counter Indirect with Index (8-Bit Displacement) Mode". Given that I'm only now learning Motorola 68000 assembly, I wanted to confirm my understanding and to ask: what is the proper syntax for these operations?

I've been playing around with x87 FPU programming,and I just came across the following magic spell for converting from float (32-bit) to int (32-bit):
...ANSWER
Answered 2022-Feb-25 at 13:44Quick answer:
The first magical number forces rescaling of the argument so that the LSbit of the integer part becomes rightmost-but-one in the fraction.
Then adding the second magical will erase the exponent bits.
Regarding the necessity of the last division by 2, IDK, there must be an extra technicality (probably related to the addition of 3.2^21 rather than 1.2^21).
