Book review: bash Cookbook

Filed under
Reviews

One of the reasons I love cookbooks, of all kinds, is because cookbooks have a clarity and simplicity of purpose. Whether it’s a cookbook for code geeks or for food geeks, its raison d’etre is the same: the “cook” has a job to do, and not a lot of time to do it. If a home chef wants to whip up a nice dinner for guests, he don’t want to have to understand the entire history of French cooking; he just wants a simple, well-written recipe for coq au vin. Similarly, if a sysadmin wants to receive an hourly email with a list of zombie processes on the new test server down the hall, she probably wants to hack together a quick bash script, and she doesn’t want to read the collected works of Grady Booch to do it.

Therefore, for me, the best benchmark of a code cookbook is how effectively I can go from the idea, “I need a script to do ‘foo’,” to having a script that does “foo” effectively. It was with this purpose in mind that I set O’Reilly’s new bash cookbook down next to me.

Android Leftovers

IT runs on the cloud, and the cloud runs on Linux. Any questions?

A recent survey by the Uptime Institute of 1,000 IT executives found that 50 percent of senior enterprise IT executives expect the majority of IT workloads to reside off-premise in cloud or colocation sites in the future. Of those surveyed, 23 percent expect the shift to happen next year, and 70 percent expect that shift to occur within the next four years. Read more

Security Leftovers

  • Teardrop Attack: What Is It And How Does It Work?
    In Teardrop Attack, fragmented packets that are sent in the to the target machine, are buggy in nature and the victim’s machine is unable to reassemble those packets due to the bug in the TCP/IP fragmentation.
  • Updating code can mean fewer security headaches
    Organizations with high rates of code deployments spend half as much time fixing security issues as organizations without such frequent code updates, according to a newly released study. In its latest annual state-of-the-developer report, Devops software provider Puppet found that by better integrating security objectives into daily work, teams in "high-performing organizations" build more secure systems. The report, which surveyed 4,600 technical professionals worldwide, defines high IT performers as offering on-demand, multiple code deploys per day, with lead times for changes of less than one hour. Puppet has been publishing its annual report for five years.
  • Over half of world's top domains weak against email spoofing
    Over half of the world's most popular online services have misconfigured servers which could place users at risk from spoof emails, researchers have warned. According to Swedish cybersecurity firm Detectify, poor authentication processes and configuration settings in servers belonging to hundreds of major online domains are could put users at risk of legitimate-looking phishing campaigns and fraudulent emails.
