I have built a similar website to reddit / hacker news but hopefully made it a touch better without loads of adverts all over the place and AI bots hanging about. I would be interested to see what people think and for some feedback. \> www.upvote.social

Suppose I have a class force_generator defined in the following code: import numba import numpy as np class force_generator(object): def __init__(self, a, b, c): self.a = a self.b = b self.c = c def force(self, x): if x > 0: return self.a*x**2 + self.b*x + self.c else: return self.b*x def simple_force(self, x): return self.a*x**2 + self. @numba.jit def euler_integration(force, x_0=0, v_0=0, m=1, dt=1e-3, t=10): steps = int(t//dt) X, V = np.zeros(steps), np.zeros(steps) X[0], V[0] = x_0, v_0 for i in range(1,steps): V[i] = force(X[i-1])*dt/m X[i] = V[i]*dt return X, V example_simple_force = numba.jit(lambda x: x**2 + 2*x + 1) example_force = numba.jit(lambda x: (x**2 + 2*x + 1)*(x>0) + (2*x)*(~(x>0))) example_generator = force_generator(1, 2, 1) X, V = euler_integration(example_force) print(X) print(V)

I recently purchased and installed Delphi 13. The .exe file, along with the .dcu files, are placed in win32/debug or win32/release. Often, however, the files are not visible and the win32/debug, win32/release folder properties show 0 folders and 0 files. But sometimes, the files are visible. I found that searching for a file known to exist, however, finds the file in win32/debug or win32/release. Sometimes on a restart, the .dcu and .exe files subsequently show up. How can I get the files to show up after a compile or build?

Can We Save Stack Overflow with AI? A Proposal The Current Crisis Stack Overflow is struggling. Traffic and engagement are declining due to AI tools like ChatGPT. The platform developed a reputation for being hostile toward beginners, with aggressive duplicate marking and sarcastic comments. Experts became tired of answering repetitive basic questions, and new developers started preferring ChatGPT where there's no social judgment. My Idea: AI as First Responder Here's how it would work: Step 1: User asks a question (Type, Title, Body, Tags as usual) Step 2: AI generates an immediate response, clearly marked as "AI-Generated Response" Step 3: The community participates by: Rating the response (upvote/downvote) Adding alternative or complementary answers Correcting errors in the AI response Expanding with

A 1-d array of ints sorts correctly. An array of arrays of ints does not sort as ints; it sorts as strings. (10,2) | Sort-Object This works and is sorted as ints. 2 10 $a1 = [int[]](10,1) $a2 = [int[]](2,1) $a1,$a2 | Sort-Object | ForEach-Object {'--';$_} This does not work. The 10 and 2 are sorted as strings, not as ints. -- 10 1 -- 2 1 Does anybody have a fix or workaround? Q Powershell GitHub issue was opened to address this behavior on Oct 25, 2022, but it was closed for housekeeping purposes after six months of inactivity on Nov 22, 2023. https://github.com/PowerShell/powershell/issues/18389 This problem

I have a quarkus web app currently protected by Apache's form-based authentication via reverse proxy. # conf.d/session-auth.conf.inc AuthType form AuthFormProvider file AuthUserFile ... AuthFormLoginRequiredLocation /web/login.html ... # httpd.conf <Location /app-name> ProxyPreserveHost On ProxyPass ... ProxyPassreverse ... Labels on Include conf.d/session-auth.conf.inc <RequireAll> Require valid-user </RequireAll> </Location> I had to play games to copy the authenticated user id to the request header by adding the following to the Location block above: RewriteEngine on RewriteCond %{REMOTE_USER} (.*) RewriteRule .* - [E=ENV_REMOTE_USER:%1] RequestHeader set X-Proxy-REMOTE-USER %{ENV_REMOTE_USER}e ...but what I would really like is to set the Principal from the Apache data. The quarkus docs have lots of information about driving t

I am trying run browser_use Agent actions such as clicks, typing, and screenshots inside an E2B sandbox Chrome instance, not local Chrome. Currently, the agent spawns local Chrome processes even though I pass browser_url=wss://e2b-chrome-endpoint. import asyncio import json from e2b import Sandbox from browser_use import Agent, ChatOpenAI from dotenv import load_dotenv load_dotenv() async def main(): # E2B sandbox creates successfully sandbox = await Sandbox.create(template="browser-chromium") try: # Get Chrome CDP endpoint ✓ Works chrome_host = await sandbox.get_host(9222) cdp_url = f"wss://{chrome_host}" print(f"CDP URL: {cdp_url}") # Prints: wss://sandbox-abc123.e2b.dev # Agent ignores remote browser - spawns LOCAL Chrome llm = ChatOpenAI(model="gpt-4o-mini") agent = Ag

Completely stumped fiddling with .htaccess in a CakePHP app. Checked a few SO posts and Perplexity.ai LLM. But still getting erroneous results. Trying to do a simple full host redirect, but skip the rule if the substring "cheezit" is found in the request. I've been able to print out the server variables like %{REQUEST_URI} so I know they have the expected input values. There is no other contents in the .htaccess file. # .htaccess RewriteCond %{HTTP_HOST} ^([^.]+)\.?old-legacy-host\.com$ [NC] RewriteCond %{REQUEST_URI} !cheezit [NC] RewriteRule ^(.*)$ https://%1.new-awesome-host.com/$1 [R=302,L] # ... whatever other rules # Original CakePHP framework directives RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php [QSA,L] When I visit https://xyz.old-legacy-host.com/cheezit/45, this URI like any other redirect

I am attempting to run a Spring Boot application from a Tomcat server, using Tomcat V9.0. Unfortunately, while this application works when I run it as a Java application, when I attempt to run it within a Tomcat container, it returns a "404: Not Found" failure. After researching the differences between deploying with Tomcat and deploying with embedded Tmcat, I created the following ApplicationBuilder class: package net.factor3.app; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.servlet.support.SpringBootServletInitializer; @SpringBootApplication public class TestApplication extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(TestApplication.cl

I'm trying to get a report sheet based on another table that contains more data i have succeeded in creating the date column based on the available dates in the other table using =UNIQUE(FILTER(Table13[DATE],Table13[DATE]<>"")) which listed the dates, i want to calculate the sum of these dates, i have tried =SUM(UNIQUE(FILTER(Table13[AMOUNT],Table13[AMOUNT]<>""))) but it's showing me a strange total. sample: https://docs.google.com/spreadsheets/d/1UqcHQBSwiYVzEd0lESEqlgoHymoR08qy/edit?usp=drive_link&ouid=111206627585463999752&rtpof=true&sd=true Thanks
