OpenAI’s API Now Available with No Waitlist

OpenAI’s API is now available to developers in supported countries. The waitlist for GPT-3 has been removed thanks to new safeguards. There is now a free content filter to help developers mitigate abuse, and OpenAI will review applications before they go live, monitor for misuse, and support developers as their product scales. OpenAI has updated its Content Guidelines to clarify what kind of content its API can generate. More use cases will be allowed over time as the system is improved.

OpenAI is committed to the safe deployment of AI. Since the launch of our API, we’ve made deploying applications faster and more streamlined

Enable Apple AirPrint support on any USB Printer with a Raspberry Pi

A short and easy setup

1. Install Raspbian on a SD card

2. Mount SD card on some machine and navigate to /. Add a file called ssh and set up wpa_supplicant.conf for WiFi access. Now you have headless and don't need a keyboard or monitor.

3. Boot. Login. sudo raspi-config. Change password.

4. Connect printer via USB cable

5. Then execute the following sequence of commands to set up CUPS and make it accessible on the network.

sudo apt-get update

sudo apt-get full-upgrade

sudo apt-get install cups

sudo usermod -a -G lpadmin pi

sudo cupsctl --remote-any

sudo systemctl restart cups

6. Visit http://raspberrypi:631/admin and add the local printer. Make sure "sharing" is enabled on the printer.

7. Then make sure AirPrint is set up

sudo apt-get install avahi-daemon

sudo reboot

Printer should work now via AirPrint.

Facebook Banned Me for Life Because I Help People Use It Less

Unfollow Everything was a #Chrome extension that helped #Facebook users unfollow all their friends and pages on Facebook, resulting in an empty News Feed. The creator of the extension discovered that their Facebook use dramatically decreased after unfollowing everything. Unfollowing people and pages is not the same as unfriending them as you can still see what people are up to if you want to. After a few months, Facebook sent a cease and desist to the developer and deleted their Facebook and Instagram accounts. This experience highlights Facebook's anti-consumer behavior, showing how the platform acts to limit user choices.

Facebook’s behavior isn’t just anti-competitive; it’s anti-consumer.

TCP port scanner, spews SYN packets asynchronously, scanning entire Internet in under 5 minutes.

MASSCAN is a TCP port scanner that can scan the entire Internet in under 5 minutes from a single machine. It uses parameters similar to nmap. MASSCAN can send 300,000 packets per second on Windows and 1.6 million packets per second on Linux. It randomizes target IP addresses, so it shouldn't overwhelm any distant networks.

BioNTech mRNA Cancer Vaccine moves to Human Trials

#BioNTech has been testing the use of #mRNA vaccines against cancer. Animal trials have shown great promise, so the technology is now in human trials to see if they can bring the same success. Cytokines are proteins with anti-tumor effects. Research has shown that they can shrink tumors and even eradicate them, but they have a short half-life, and high levels of cytokines in the body results in adverse effects. The experimental vaccines encode cytokines directly into the tumors, creating them in large quantities without adverse effects.

Following the explosive success of mRNA vaccines against COVID-19, BioNTech is turning its attention to cancer. Their new treatment, using s
