An unresponsive service is worse than a down one. It can tie up your entire system if not handled properly. All network requests should have a timeout.

Here’s how to add timeouts for popular Ruby gems. All have been tested. You should avoid Ruby’s Timeout module. The default is no timeout, unless otherwise specified. Enjoy!

httpry
httpry is a specialized packet sniffer designed for displaying and logging HTTP traffic. It is not intended to perform analysis itself, but to capture, parse, and log the traffic for later analysis. It can be run in real-time displaying the traffic as it is parsed, or as a daemon process that logs to an output file. It is written to be as lightweight and flexible as possible, so that it can be easily adaptable to different applications.

How to Create a Large Wireless Network
One day I had to install a network for 8,500 square feet (850 m2) of living space, all on one level, and cover almost an acre of land outdoors. That required several wireless devices, all connected together.

It's easy to do, but only if you know which secret boxes to click in the set up program.

Oddly no one has written down how to do it — until now.

Here's how.

ngrok - secure introspectable tunnels to localhost
“I want to securely expose a local web server to the internet and capture all traffic for detailed inspection and replay.”

ngrok creates a tunnel from the public internet (http://subdomain.ngrok.com) to a port on your local machine. You can give this URL to anyone to allow them to try out a web site you're developing without doing any deployment.

ngrok captures all traffic through the tunnel. It displays information about the HTTP traffic for your inspection. Raw request/response bytes, parsed headers and form data, JSON/XML syntax checking and more are included.

Developing services which consume webhooks can be challenging if the hooks are labor-intensive to generate. Use ngrok's replay request feature to iterate quickly on a new feature without switching contexts to generate new requests.

xip.io: wildcard DNS for everyone
xip.io is a magic domain name that provides wildcard DNS
for any IP address. Say your LAN IP address is 10.0.0.1.
Using xip.io,

10.0.0.1.xip.io resolves to 10.0.0.1
www.10.0.0.1.xip.io resolves to 10.0.0.1
mysite.10.0.0.1.xip.io resolves to 10.0.0.1
foo.bar.10.0.0.1.xip.io resolves to 10.0.0.1

...and so on. You can use these domains to access virtual
hosts on your development web server from devices on your
local network, like iPads, iPhones, and other computers.
No configuration required!

Paypal, Reddit and The Power Of Fakin’ It | Platform Thinking
This is because there is no inherent value in the standalone product for a user (eBay, Quora) without the participation of users from the other side who create complementary products (goods for sale, answers). When users come to the platform, they need to get an indication of activity. Some community owners, as in the case of MegaUpload, solve this by creating a false aura of activity using a variety of methods.

Now, the iPhone 5, the latest iPod touch, the fourth-generation iPad, and the iPad mini also have that support. So, how do you set up a Wi-Fi network that makes the most of this confluence of Wi-Fi bands?

Configurar seu Mac para simular uma impressora (PDF-printer) | AURELIO.NET
No Mac isso é trivial, pois sempre que você manda imprimir algo, aparece a opção Salvar como PDF. Então não importa se é um email, um site ou um documento que você está editando. É só mandar imprimir e com o clique de um botão você poderá arquivá-lo em um PDF. Depois, se precisar, você imprime o PDF numa impressora de verdade.

Mas e se você estiver em outra máquina na rede local (Windows, Linux) ou no celular e quiser imprimir, digo, salvar como PDF em seu Mac?

Uma solução bacana é configurar seu Mac para ele fingir ser uma impressora na rede, assim você pode mandar “imprimir” coisas nele. Na verdade, o que ele fará é salvar um PDF daquilo que você mandou imprimir. Para os outros computadores essa operação é transparente, eles enxergarão seu Mac como uma impressora de verdade e nunca saberão que foram enganados :)

Welcome to DenyHosts
DenyHosts is a script intended to be run by Linux system administrators to help thwart SSH server attacks (also known as dictionary based attacks and brute force attacks). If you've ever looked at your ssh log (/var/log/secure on Redhat, /var/log/auth.log on Mandrake, etc...) you may be alarmed to see how many hackers attempted to gain access to your server. Hopefully, none of them were successful (but then again, how would you know?). Wouldn't it be better to automatically prevent that attacker from continuing to gain entry into your system?

Local DNS Cache for Faster Browsing « Ubuntu Blog
You can run a DNS cache on your computer. This will speed up the process of looking up domain names when browsing. The difference is about 30-60 ms for me. Multiply that difference by the number of websites you visit a day for an approximate estimate of the speed improvement. Of course, all this would be worth it if it weren’t for the fact that setting this up is way too easy.
