• Robin Rendle ☛ Hire HTML and CSS people

  Every problem at every company I’ve ever worked at eventually boils down to “please dear god can we just hire people who know how to write HTML and CSS.”

• University of Toronto ☛ Our broad reasons for and approach to mirroring disks

  When I talked about our recent interest in FreeBSD, I mentioned the issue of disk mirroring. One of the questions this raises is what we use disk mirroring for, and how we approach it in general. The simple answer is that we mirror disks for extra redundancy, not for performance, but we don't go too far to get extra redundancy.

• Ryan Mulligan ☛ Web Components for Password Input Enhancements

  So there I was, experimenting with HTML password inputs and Web Components. I'm not sure why the idea even came up but it quickly snowballed into a curious expedition. The result from the journey was a set of custom elements that provide extra functionality and information about the text being typed into a password input field. I shared my CodePen demo in a Mastodon post and soon after decided to push these scripts up to a GitHub repo.

• Hackaday ☛ When Raw Network Sockets Aren’t Raw: Raw Sockets In MacOS And Linux

  Raw network sockets are a curious beasts, as unless you have a strong urge to implement your own low-level network protocol, it’s a topic that is probably best left to the (well-paid) experts. That said, you can totally use raw sockets in virtually every operating system, but one should be aware of a few things, the lack of portability being one of them. This is what tripped [Swagnik] up while trying to write a low-level network ping (ICMP) utility, by reading the Linux socket documentation while testing on MacOS. It’s all BSD-style sockets, after all, right?

• nixCraft ☛ Linux / UNIX View Only Configuration File Directives ( Uncommented Lines of a Config File )

  Most GNU/Linux and UNIX-like system configuration files are documented using comments, but sometimes I just need to see a line of configuration text in a config file. How can I view just the uncommented configuration file directives from squid.conf or httpd.conf file? How can I strip out comments and blank lines on a GNU/Linux or Unix-like system?
