Can I have a DF steer?

The old DF steer came onto my radar today (if you’ll excuse the irony), so not having flown for far too many years I thought I’d look it up, just out of curiosity. Seems they are being or have been decommissioned in a lot of places.

But what really struck me in the few discussions I read about them was the incredibly narrow view of some of the pilots discussing them. Sure, as we all know, the USA is the centre of the universe in many ways, not the least of which is aviation, but the ability to fly is supposed to broaden your outlook (and particularly your world view), especially if you can talk about zipping a couple of hundred nautical miles away (or over to the next continent, depending on your equipment!) to have lunch and be back in time for dinner. And yet, here were all these pilots (most of them US-based) talking about DF steers and radar coverage as if the former are no longer available anywhere on the planet, and the latter covers every square centimetre of the planet.

Weird.

Fashion

Boring. Boooooooring! That one word pretty much sums up my fashion sense, if you can even call it that.

I vaguely remember — in the seventies — having a “parachute jacket” that I thought was pretty cool. All I can remember now is that it was bright yellow (probably not quite as bright in reality as it is now in my memory, or maybe it was brighter!), had zips and press studs and the texture of the material out of which they make parachutes — hence the name. And I think I probably bought (or had bought for me by my parents) a few pairs of jeans that were probably fairly cool back in their day … flares, stovepipes, pockets galore with flaps and/or zips, etc.

But these days — and for most of my life from my teens onwards — my attire has been pretty utilitarian. Truth is, if the law and the weather permitted it and I had somewhere to put my wallet (a sporran perhaps?), I’d walk around buck naked all day. So my default attire in public is shorts (I mean real shorts, not those stupid “short trousers” that go all the way down to your knees, or further!) and T-shirts and slops in the summer, and jeans, T-shirts and shoes & socks in the winter. In the winter I’ll take a jacket if I’m driving somewhere (I’ll actually wear a lighter one if I’m walking), but it will likely stay in the car until my return home. (Friends are always asking me, as I leave their places after an evening, “Didn’t you bring a jacket?!”) My use (or lack thereof) of jackets is a topic unto itself for another time.

I do own khaki pants, golf shirts, plaid shirts and other long- and short-sleeved collared shirts, dressier black Oxford Brogues than my current, everyday, brown Derby-type shoes, a sports coat, suits (double- and single-breasted), about two dozen ties (ranging from plain black for funerals to far more ostentatious and whimsical ones) and half a dozen bow ties. However, the dressier things get the fewer the opportunities I have for wearing them, especially considering I work from home. Actually, I really do lament that as I do like to dress up (and I think I rock a well-fitting suit, even if I do say so myself), but I can’t make up events that don’t exist and I’m too practical to put on a suit just to go and visit friends for the evening.

I do care what I look like when I leave the house, but I don’t care enough to go to ridiculous ends and spend ridiculous amounts of money and time on my appearance. And I mostly will not wear what mainstream fashion tells me I should wear, so I’m a bloody-minded contrarian to boot.

The reason I bring this up is an article on “lumbersexuals” on The Daily Beast. One paragraph really spoke to me:

But the rough-looking, dependably butch lumbersexual, despite his honest-guy uniform, is a drag queen, just as we all are. On go our costumes every day, and so it especially is with those whose uniform is dedicated to looking like they care least of all what they look like. The lumbersexual is the biggest drag queen of them all.

Now, I have never until today heard the term “lumbersexual”; I own two plaid shirts that I rarely wear (and only one of them is flannel) and it is quite clear to me that the guys I have seen pictured in articles I have now read about them spent a lot more than “20 minutes of [their] morning[s] delicately trimming [their] beard[s] in the bathroom mirror“. I have also grown full beards, although I’m not that fond of them. But I squirmed uncomfortably at the thought that maybe the attire that results from my “studied disinterest” (to quote my father) in fashion is, in itself, a fashion statement.

If it is, I may as well pull out my wallet and head to the nearest trendy clothing shop and ask someone there to dress me properly in some hip new threads. (Irony intended.) The problem is, I just can’t stand waste, and I’ll still be wearing in five years what is trendy today. I can’t win!

Deleting files under Linux/Unix

Today I came across a comment on a blog post related to deleting files on a Unix/Linux system that was a clear case of bullshit. I tried to post a comment to that effect on the blog in question, but the comment feature was broken. So, since I had already gone to the trouble of writing my response, and since I don’t post nearly as much to my own blog as I would like, I’ll just post it here instead.

To PoorMe, who claimed to have “just lost all of [his/her] files and folders on [his/her] server in just 2 seconds” by running the suggested command, I call bullshit!

I actually intentionally tried this a few years ago on a server that I was decommissioning. First of all, you have to be in the root directory for the dreaded “rm -rf *” command to try and remove everything (unless you craft the command explicitly to remove everything under the root directory), and you’re almost never in the root directory unless you place yourself there for some specific and very unusual reason.

Secondly, in my test (which I did run as root) I ran into many files and directories that threw up errors and interrupted the process, even though I used the “-f” flag. In fact, I ended up having to delete individual directories off of the root to do what I was trying to achieve, and even then I gave up trying to remove anything but directories I knew contained user data.

Thirdly, even without those errors the process would have taken minutes, if not hours, not “2 seconds”. Anyone who thinks it takes two seconds has obviously never tried it. Besides, assuming you’re connecting over SSH, how are you still connected if you deleted everything, including the SSH server?

Bottom line, don’t run commands on your system that you find on the Internet without first understanding and checking them. But even if you don’t take that advice, the chances of you erasing every file and directory on your server in the blink of an eye are close to zero. Sure, you might erase a whole lot of stuff you didn’t want to erase that you may never get back and which may destabilise your system requiring you to reinstall the operating system (and it may happen in as few as two seconds), but what PoorMe claims happened almost certainly didn’t happen.

Happy Birthday Christopher!

Dear Christopher,

Happy birthday.

Love, Uncle Craig
