I am developing a cross-platform security agent mainly focused on Windows. In future I might need a similar approach for macOS. One of the critical features is a "temporary suspension" mode which is controlled by the IT admin where the agent stops monitoring for a specific duration. The Problem: Users might try to extend suspension periods by manually changing the system clock (wall clock) while the agent is offline. (I can use a trusted server to retrieve current time when the agent is online) Since my product relies on time-based logic, I need to ensure that the system time hasn't been tampered. Current Approach: I am currently using a background thread that polls every 2 seconds. It compares the std::chrono::system_clock (which can be affected by user) against std::chrono::steady_clock (which is monotonic and should not jump). This approach doesn't seem a correct way. I am looking

Is it possible to write something like this: <div classname="bg-primary-200"></div> and then set the primary color to one of the colors from the tailwind colors in my global css: --primary-color: blue and then the 200 shade of blue is applied.

I am trying to use aws cloud shell. I am getting this error since 4 month not resolved. I have tried everything. "Unable to create the environment. Your account verification is in progress. This may take up to two days for new accounts. If you have any further questions, contact AWS Support . To retry, delete the environment by selecting Actions, Delete and then try again." Not sure what account permissioned I messed up.

I'm trying to figure out how does this lazy initialization make any sense. As far as I knew, integer values are always passed by values, but it seems like it's not: class Lazy: def __init__(self, factory): self._factory = factory self._value = None def _init(self): if self._value is None: self._value = self._factory() def __getattr__(self, name): self._init() return getattr(self._value, name) tmp = [] for el in [1, 2, 3]: tmp.append( Lazy(lambda : {"value":el}) ) print(tmp[0].get("value")) I'd expect to see `1` as output, but instead it's `3`... reason? because `el` seems to be assigned by reference. However: class Lazy: def __init__(self, factory): self._factory = factory self._value = None def _init(self): if self._value is None: self._va

In a script I'm using constants (use constant ...) to allow re-use ion actual regular expressions, using the pattern from https://stackoverflow.com/a/69379743/6607497. However when using a {...} repeat specifier following such constant expansion, Perl wants to tread the constant as a hash variable. The question is how to avoid that. Code example: main::(-e:1): 1 DB<1> use constant CHARSET => '[[:graph:]]' DB<2> x "foo" =~ qr/^[[:graph:]]{3,}$/ 0 1 DB<3> x "foo" =~ qr/^${\CHARSET}{3,}$/ Not a HASH reference at (eval 8)[/usr/lib/perl5/5.26.1/perl5db.pl:738] line 2. DB<4> x "foo" =~ qr/^${\CHARSET}\{3,}$/ empty array DB<5> x $^V 0 v5.26.1 According to https://stackoverflow.com/a/7984501

So, this is my best idea at getting around Steam's rate limit that ChatGPT made into reality, I wonder how bad this is? I have 0 coding knowledge btw. If you see this, could you give some suggestions to improve it? I would appreciate it. It is supposed to work like this: Open a web browser and open the urls that have been put in automatically After the pages load, it runs another script which looks for stickers and charms (keychain) Then, if something that satisfies a condition is there it leaves the page open, outputs a checkmark Otherwise, every page closes. const puppeteer = require('puppeteer'); (async () => { const urls = [ 'https://steamcommunity.com/market/listings/730/AK-47%20%7C%20Slate%20%28Battle-Scarred%29', 'https://steamcommunity.com/market/listings/730/AK-47%20%7C%20Slate%20%28Field-Tested%29', 'https://steamcommunity.com/market/listings/730/AK-47%20%

We are encountering a PostgreSQL exception stating that the maximum number of columns (1664) has been exceeded. The query in question attempts to select more than 3,000 columns as there are multiple huge forms. The data is going to increase eventually. Each column extracts a value from a table that contains a JSON column. Our use case involves large survey-style forms with hundreds of questions, each identified by a unique field ID. All responses are stored in a single table, where: Each row represents a respondent A JSON column maps field IDs to their corresponding answers To analyze this data, we currently generate a very large query that reads individual values from the JSON column and exposes them as separate columns. This approach results in a query that exceeds PostgreSQL's column limit, triggering the exception. Could you suggest a better approach to handle this use case?

I'm using React 18.3, Highcharts 12.3.0 and highcharts-react-official 3.2.2. I had a problem setting up Highcharts to show the export button before but I somehow managed to make it work with those lines : import Highcharts from "@/lib/highcharts_config"; import HighchartsReact from 'highcharts-react-official'; import * as expData from "highcharts/modules/export-data"; import * as exp from "highcharts/modules/exporting"; import * as offExp from "highcharts/modules/offline-exporting"; console.log(exp); console.log(expData); console.log(offExp); Originally, I just put the console logs for debugging purposes and also to avoid the ESLint warnings because expData, exp and offExp are never called in my code and everything just worked somehow. Yesterday I was working on an API from which I get the data to plot on the c

Consider the following DataFrame: df = pl.DataFrame({ "a":[ ["55", "87.19"], ["55.11","55.12"], ["55", "27.89"] ] }) I would like to replace all "55" with "55.11", "55.12". That is, I would like the end result to be: df = pl.DataFrame({ "a":[ ["55.11","55.12", "87.19"], ["55.11","55.12"], ["55.11","55.12", "27.89"] ] }) How can I achieve that?
