Is there a limit number of use os.execl() in python?

Program Background:

  • Goal of my program is to get stock trade datas from a stock firm’s open API.
  • (I think this is not important..) API supports only 32bit Python, Windows and OCX.
  • There is a limit frequency on API usage; >100times/1min.
  • The data is too huge and the limit is too tight I think.
  • So I overcome this limit issue by using "os.execl()" to reload the process and initialize the limit.

Here my Problem is:

  • After 128 times of "os.execl()" reloaded, program completely STOPS and do NOTHING!

More info:

  • I think this is not an API problem.
  • Because when I tried "os.execl()" with only "print(‘hello world’)" in it, it came out the same result. After 128 times, it stops.

My Question is:

  • Is there a limit number of use "os.execl()" in python?
  • If so, what should I do to overcome this?
  • If not, what would be the cause of this problem you think?

Thank you for reading and hope everyone visited this post have a good day.

pr.probability – Central limit theorem for chi-squared random field on $mathbb R^p$

Let $X:x mapsto X(x)$ be a centered stationary Gaussian process on the $Omega:=mathbb R^p$, such that $X(x) overset{d}{=}X(x’)$ for all $x,x’ in Omega$. Set $sigma^2 := mbox{Var}(X(0)) = mathbb E(X(0)^2)$. Let the random fields $X_1,ldots,X_N$ be iid copies of $X$, and define a random process $Z_N$ on $Omega$ by
$$
Z_N(x) := frac{1}{sqrt{2Nsigma^2}} left(sum_{i=1}^N X_i(x)^2-Nsigma^2 right),;forall x in Omega.
$$

Question. Is there a central limit theorem (perhaps under further conditions on the base field $X$) for the limiting distribution of the random field $Z_N$ when $N to infty$ ?

So. Limit access by user permission on Drupal 8. How can I solve it?

Background process limit in developer options doesn’t work on Samsung Galaxy S10

I’m using debloated Samsung Galaxy S10. When I set the background limit to any number or none, it doesnt work. I checked the cached process in running services, there are more than 5 apps.

Any solution?

real analysis – How to prove the following limit exists?

Consider the following definition of generalized directional derivative in the book Optimization and Nonsmooth Analysis, Clarke:

$$f^circ(x,v)=limsup_{trightarrow 0^+,~yrightarrow x}dfrac{f(y+tv)-f(y)}{t}$$

First of all how do you interpret this limit?

How to prove it exists (assuming $f(cdot)$ Lipschitz)?

google sheets – Limit number of rows

I have a Google Sheets document that keeps adding hundreds of rows and slowing down the project, and sometimes causing it to crash.

Is there a way to limit the number of rows to say 100. I do not want to remove all empty rows, because it is a log that constantly needs data added to so a new row is always needed. However, we only use around 100 rows for each document.

I am not sure if this is due to a script I have attached or if it is just part of google sheets.

   function setFormat() {

    var ss = SpreadsheetApp.getActiveSpreadsheet();
    var sheets = ss.getSheets();
for (var i in sheets) {
    var MaxRows = sheets(i).getMaxRows();

sheets(i).getRange(2, 1, MaxRows, MaxColumns)
.setFontFamily('Arial')
.setFontSize('9')
.setFontStyle('normal')
.setFontColor('black')
.setVerticalAlignment('center')
.setBorder(true, true, true, true, true, true, "black", SpreadsheetApp.BorderStyle.SOLID);

sheets(i).getRange(1, 1, 1, MaxColumns)
.setFontFamily('Comfortaa')
.setFontSize('9')
.setFontStyle('bold')

sheets(i).setColumnWidths(2, 1, 80);
sheets(i).setColumnWidths(3, 1, 75);
sheets(i).setColumnWidths(4, 1, 90);
sheets(i).setColumnWidths(5, 4, 45);
sheets(i).setColumnWidths(9, 3, 75);
sheets(i).setColumnWidths(12, 2, 130);
sheets(i).setColumnWidths(14, 1, 95);
sheets(i).setColumnWidths(15, 1, 100);
sheets(i).setColumnWidths(16, 1, 95);
sheets(i).setRowHeights(2, MaxRows-1, 15);
sheets(i).setRowHeights(1, 1, 16);   }}

calculus of variations – epsilon delta proof of limit

I am trying to learn the epsilon delta proof of limit. I am a little confused why we always consider that epsilon>0, like if the discontinuity point of the graph is below the x axis, then nearest value or range to limit will also be in the negative part, in that case value of epsilon will be smaller than zero.

questionnaire – Can using graded scale help limit number of “Don’t knows”?

Obviously the more options you present, the more likely it is that they will use them rather than just selecting “Don’t Know” – unless they actually don’t know the song of course. So directly answering your question, yes it will help if you have more options.

However, if you are asking a user to rate a song then you should opt for a more familiar approach. Allow the user to select a rating score. For example, let them select from 0-5 stars, or a 1-10 rating, etc. This easily covers the “grey areas” and nearly all users will be familiar with this concept.

With regards to handling the “don’t knows” in a rating system. Either allow the user to not select a rating and skip that song, or if you want explicit action to confirm it then just have a button next to the rating control for “I don’t know this song”.

rom flashing – How to flash /system using twrp when system.img is 1.7GB and internal storage has 1.5GB max limit

I happen to have an old phone laying around with messed up system partition(a couple of files accidentally deleted). This phone has an internal storage of max 1.5 GB(total 4gb, after setting everything up leaves me with 1.5 GB). I downloaded the stock firmware for the phone and the system.img size is almost 1.7GB I have twrp recovery. Is it possible to flash with an external sdcard.
N.B: I unfortunately don’t have my pc with me atm.
