  • Security updates for Thursday
  • It just got much easier to wage record-breaking DDoSes

    Now, two separate exploits are available that greatly lower the bar for waging these new types of attacks. The first one, called Memcrashed, prompts a user to enter the IP address to be targeted. It then automatically uses the Shodan search engine to locate unsecured memcached servers and abuses them to flood the target. Here's a screenshot showing the interface: [...]

  • Push to bolster election security stalls in Senate

    But Lankford on Wednesday was forced to table an amendment to a bill moving through the Senate that was aimed at improving information-sharing between federal and state election officials on election cyber threats. State officials objected to the amendment.

  • Senate committee approves bill reorganizing Homeland Security’s cyber office

    A key Senate panel on Wednesday advanced legislation to reauthorize the Department of Homeland Security (DHS) that includes a measure reorganizing the department’s cybersecurity wing.

    The bill includes language that would reorganize and rename the office within the department that protects federal networks and critical infrastructure from physical and cyber threats, currently known as the National Protection and Programs Directorate (NPPD). Under the legislation, the entity would be transformed into an operational agency called the Cybersecurity and Infrastructure Security Agency.

Five-Way Linux OS Comparison On Amazon's ARM Graviton CPU

Last month Amazon rolled out their "Graviton" ARM processors in the Elastic Compute Cloud. Those first-generation Graviton ARMv8 processors are based on the ARM Cortex-A72 cores and designed to offer better pricing than traditional x86_64 EC2 instances. However, our initial testing of the Amazon Graviton EC2 "A1" instances didn't reveal significant performance-per-dollar benefits for these new instances. In this second round of Graviton CPU benchmarking we are seeing what is the fastest of five of the leading ARM Linux distributions. An Amazon EC2 a1.4xlarge instance with 16 cores / 32GB RAM was used for this round of benchmarking across the five most common ARM Linux distributions that were available at the time of testing on the Elastic Compute Cloud. The tests included: Amazon Linux 2 - The reference Amazon Linux machine image with the Linux 4.14 kernel and GCC 7.3. Read more

Take a swim at your Linux terminal with asciiquarium

We're now nearing the end of our 24-day-long Linux command-line toys advent calendar. Just one week left after today! If this is your first visit to the series, you might be asking yourself what a command-line toy even is. We’re figuring that out as we go, but generally, it could be a game, or any simple diversion that helps you have fun at the terminal. Read more

Photography and Linux

So, as you can see, except for the printing step, pretty much the whole workflow is handled very easily by Linux and open-source photography software. Could I have done the whole thing in Linux? Yes and no. Depending on your printing needs, you could forego the printer entirely and use a local professional printing service. Many of those shops use the ROES system for the uploading and management of images to be printed. The ROES client is written in Java and is compatible with Linux. If you invest in a large format printer, you may have to investigate using a solution similar to what I have set up. Open-source software RIPs exist, but they have not been updated for more than a decade. Some commercial Linux solutions are available, but they are prohibitively expensive. Read more
