server

问题 I am trying to learn ruby on rails using the michael hartl guide. In the past, I was able to get through the setup of a new rails webapp. Now, when I try to run the server, I am getting this error: /home/ss/.rvm/gems/ruby-2.2.2/gems/fog-1.26.0/lib/fog/joyent/compute.rb:3:in `require': cannot load such file -- net/ssh (LoadError) from /home/ss/.rvm/gems/ruby-2.2.2/gems/fog-1.26.0/lib/fog/joyent/compute.rb:3:in `<top (required)>' from /home/ss/.rvm/gems/ruby-2.2.2/gems/fog-1.26.0/lib/fog/joyent

问题 So I'm trying to web crawl clothing websites to build a list of great deals/products to look out for, but I notice that some of the websites that I try to load, don't. How are websites able to block selenium webdriver http requests? Do they look at the header or something. Can you give me a step by step of how selenium webdriver sends requests and how the server receives them/ are able to block them? 回答1: Selenium uses a real web browser (typically Firefox or Chrome) to make its requests, so

问题 I've created a minimal application around Java's HttpsServer. I've installed an HttpHandler that replies to a request with a short text message: return exchange -> { try { OutputStream responseBodyStream = exchange.getResponseBody(); byte[] response = "Trouble with HTTPS and curl\n" .getBytes(StandardCharsets.UTF_8); exchange.getResponseHeaders().set("Content-Type", "text/plain"); exchange.sendResponseHeaders(200, response.length); responseBodyStream.write(response); responseBodyStream.close(

问题 I am using the PyCUDA to implement the smooth_local_affine as shown here. It works well when I simply run the program on linux. But when I tried to import it under Flask context: from smooth_local_affine import smooth_local_affine from flask import Flask app = Flask(_name_) ... The following error occurs: ------------------------------------------------------------------- PyCUDA ERROR: The context stack was not empty upon module cleanup. -------------------------------------------------------

问题 I'm running a PHP loop that 'scans' a directory, every 60 seconds, until a file with a given name is found: <?php do { if (file_exists("../path/file.txt)) { //Do Stuff $status = "File Found"; echo $status; } else { $status = "File Not Found"; sleep(60); } } while ($status == "File Not Found"); ?> In this example, would removing sleep() require more server resources? Thank you, 回答1: In a nutshell, yes, but don't worry about it. While sleep is executing, CPU processing of your script virtually

问题 I am new to WebRTC. I need to configure my own turn server for my webrtc application. I was installed my turn server using the below command. apt-get install coturn I need to run the turn server over tcp only. It don't have to use the UDP for anything for the media transfer also it have to use the TCP only. So, I was run the turn server using the below command. turnserver -n -a -v --no-udp --min-port 9002 --max-port 9008 --no-dtls -r "bksystems.org" --listening-port 9001 -X 13.126.11.252 -u

问题 I'm doing a project using Spark Java. On the server side, some images are created and I want them to be available in the client. Since I have a static content directory, after creating the image on the server side, I place it in that directory. However, this file is not available unless I reboot the server. I guess there must be a way to refresh the static directory file for Spark Java on runtime so that requests of on-runtime created images can be fulfilled. Right? Thanks! 回答1: The

问题 I want to access my ubuntu terminal using my browser i found a npm package web-terminal but it is kind off not complete. I have seen jupyter notebook do it. so is there a solution for it or a way to get that terminal thingy out of jupyter notebook. Example: Just like when u access your google cloud server via your browser with some sort of shell. Note: I didn't get anything to start with just the npm web-terminal so i won't be able to show much effort from my side. Thank you in advance. :D

问题 I'm embarking on watching my NGINX error.log files at level: warn... probably a silly idea and will cause me to crash my server as I work out any bugs happening, but hey, we're nerds and this is why we're here. I'm noticing a [warn] and an [emerg] pop up every time I restart my server, which shows: [warn] 8041#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1 [emerg] 8041#0: open() "/run/nginx.pid" failed (13:

问题 I did some search but could not find a suitable answer. My App should compare with multiple locations for proximity. This means I will not be able to save all the locations into my app to confirm the proximity using locationManager. I want the proximity confirmation to be done in the server What would be the best way to implement this? Would it be sensible if the app asks for proximity confirmation every time the devices moves around? 回答1: I would try a different approach, since location
