Unix and Unix-like operating systems have a command called reboot. Like the name says, it reboots the system. Veteran Unix administrators insist the correct way to reboot a Unix system is to use a cryptic command called init 6. Are they just showing off, or is there a good reason for this? It turns out there is indeed a reason why one should worry about reboot vs init 6, and using the init 6 command can protect your system.
I went to install Linux (Debian) on an old Asus socket 775 motherboard (a P5LD2) and had a litany of problems getting my installation media to boot. Here’s how I finally got it installed.
WordPress occasionally suffers from the dreaded “white screen of death,” where you visit an admin page and, instead of being able to do what you want to do, you get a blank white screen. Meanwhile, the blog continues to function. If you have scheduled posts, they keep going. But with no admin access, the blog essentially becomes a ghost ship.
Several of the causes are pretty well documented, so I’ll talk about mine instead of rehashing old advice you can easily find elsewhere. Read more
Corporations are in business to make money. That’s the premise of the classic business book The Goal, and the point of The Goal is that a lot of companies forget that.
That also means they’re not exactly happy to spend money unless there’s an obvious reason why spending that money is going to help them make more money. So that’s why you see 30-year-old minicomputers in data centers. That old system is still making the company money and with no clear financial benefit to replacing it, most businesses are perfectly happy to run the machine until the minute before it will no longer power up anymore.
That’s what makes quitting Windows XP so difficult for businesses. At this point, Windows XP and that 30-year-old minicomputer are both about as sexy as a Plymouth Volare station wagon. But they get the job done, and they’re much better than what they replaced, so the business leaders are content to just keep right on using what’s already paid for. Read more
Over the Labor Day weekend I decided to upgrade my HP Mini 110 netbook to Linux Mint 17. The Mini 110 can handle Windows 7, but Linux Mint doesn’t cost any money and I figure a Linux box is more useful to me than yet another Windows box. There are some things I do that are easier to accomplish in Linux than in Windows. Plus, I’m curious how my two young sons will react to Linux.
Linux Mint, if you’re not familiar with it, is a Ubuntu derivative that includes a lot of consumer-friendly features, like including drivers and codecs and other common software that aren’t completely open source. It’s not a Linux distribution for the Free Software purist, but having options is one of the nice things about Linux in 2014.
Linux Mint includes a lot of useful software, so once you get it installed, you’re up and running with a useful computer with minimal effort.
The NSA’s spying on Linux Journal readers is precisely what’s wrong with NSA spying. Why? It paints with an overly broad brush.
Eric Raymond’s views on many things are on the fringes of what’s considered mainstream, but he’s not the kind of person who blows up buildings to try to get his point across.
And here’s the other problem. Does Eric Raymond even represent the typical Linux Journal reader? Odds are a sizable percentage of Linux Journal readers are system administrators making $50,000-ish a year, or aspiring system administrators who want to make $50,000-ish a year, who see knowing Linux as a means to that end.
It’s no different from targeting Popular Mechanics readers because someone could use information it publishes in ways you don’t agree with. Read more
An anonymous Microsoft developer spilled some juicy opinions about why Windows kernel performance isn’t all it could be and answered some longstanding questions about Windows vs. Linux kernel performance in the process. Although he has recanted much of what he said, some of his insights make a ton of sense.
Debian 7.0 (Wheezy) came out this weekend, and I want to mess with it. Here’s how I wrote the installation media to a USB thumb drive for it using a Windows box. Because sometimes that’s all you have available to work with. If you prefer another Linux distribution, like Ubuntu or CentOS or Fedora, the same trick will work for them too.
