The perils of not checking NOTAMS

I’m in Whitby at my Dad’s place today. Because of customs, we flew to Buttonville. But then when I told the FBO guy “oh we’re not staying – as soon as we clear customs we’re heading to Oshawa” he just laughed. Evidently I carefully flight planned the trip to Buttonville, but hadn’t even looked at NOTAMs for Oshawa.

Oshawa is closed for three weeks, because they’re repaving both runways. God only knows why they couldn’t stagger them. Hey, oshawapilot, why didn’t you mention this?

Is “Redirect permanent” (301) really that hard to parse?

I just moved my blog from http://xcski.com/blogs/pt/ to https://blog.xcski.com/. I set up a “Redirect permanent” on the old location, so that anybody or anything using the old location will get automatically redirected to the new location. And for a lot of places that used to hit my blog at the old site (like rss feeders) seem to have handled the transition painlessly. For instance, NetNewsWireLite, which I use on my laptop, updated the subscription information and doesn’t appear to hit the old URL at all any more. Same with the LiveJouranl syndication.

But for some reason, a lot of them haven’t handled it correctly. For one thing, my spam load is down to almost nothing. Ok, that’s a good thing. But I also notice that some RSS feeders, like various “Planet” web sites, see a redirection from http://xcski.com/blogs/pt/feed to https://blog.xcski.com/feed, and feel like they can ignore the fact that the hostname part of the URL is different, and try to fetch the redirection at http://xcski.com/feed, which of course isn’t a valid URL. It can’t be that they have an old DNS cache entry for blog.xcski.com – it didn’t exist until a few days ago. It must be that they’re trying to be too clever, or not clever enough.

Stress, stress, and more stress.

I’m a contract programmer, a damn good one. I’m on a project that is based in Rochester NY, but which also has a programming team in China. Also, because I got this job through personal contact and reputation rather than through a headhunter, I’m very well paid. I’m sure it isn’t an exaggeration to say that the whole China team probably costs about the same as I do.

So my continued employment is probably dependant on being more productive and better than a whole team of Chinese PhDs. And so far, I’ve been doing that. Often the code they produce shows a lack of understanding of the tasks they’ve been set, or of the approach that we’ve been taking with the rest of the code that they have to work with. Although, to be perfectly honest, the biggest factor keeping me ahead of them is the fact that our higher ups are not capable of producing a clear set of requirements – but I can sit down and talk to them and build a clear picture of what is needed, or talk to the other developers and kick stuff around. I can even go to customer sites and talk to the end users. But even so, I feel a continual breathing down my neck.

Right now, we’re on a big push to produce some major new code for a new customer. I’ve been working my ass off. My code “lives” in between the user interface one of my fellow local programmers, and a module that is being produced in China. Fortunately, by working 50-55 hours a week for the last month or so, I’ve managed to keep ahead of both of them.

I’m going to see my daughters this weekend. Life events have conspired to keep me from seeing them for a while, and I need to see them this weekend. Unfortunately, I also have to do a bunch more work this weekend. Assuming I only work my “normal” 10 hours on Friday, I need to do at least 5-10 hours this weekend. That’s going to cut into the time with my daughters a bit.

I’ve got a very sore front tooth. I have a referral to a peridontist about that, since the gum is receeding so far it’s exposed much of the root. But I haven’t had time to go. And this evening walking out the car, my knee locked up in an extremely painful manner – it does that every now and then, and there’s nothing I can do about it except try to hop on the other leg. And now, right now, just to top it off, I can feel a bit of soreness swallowing. Which means that by Monday I’ll having a full grown cold, which means my productivity will be halved.

Colocation

I’ve decided to go for it.

I’m currently paying about $30 a month for a Virtual Private Server at linode.com. For that $30 a month I get the equivalent of 150Mb of RAM, 4Gb of disk, and a static IP that isn’t on any black lists. I’m guaranteed at least the equivalent of a 150MHz, but up to the maximum of the actual CPU on the machine, which is dual 3.2GHz Xeons.

The applications I run on there, particularly the Waypoint Database Generator, are severely limited by the memory limitations. I don’t come close to using all the bandwidth, and I’m not usually CPU bound. But as soon as that generator starts the memory swapping, it would use up all my io_tokens, and then the application would get i/o bound. The situation was totally untenable until somebody on linode started running a MySQL server and allowed me to use it. But I don’t like relying on this service that might go away at any time.

I’ve discovered that for about a hundred dollars a month, I can put a 1U server on a local colocation service. By going the colocation route, I can put in as much memory and disk space as I want. I still get the other advantages of the linode, such as a static IP and better bandwidth to the rest of the internet. The extra disk and memory means that I can run my own database server without getting swap and i/o bound. It also means I can move some of the disk hungry stuff like my Gallery server and this blog to it.

Yeah, it’s more expensive, but what I’m planning to do is set up the system with Xen. Then I can divide the box up into multiple virtual machines and sell shares. I’m hoping I can sell one share to start, and maybe another later on.

I’ve been perusing eBay, and it appears that $300 or so should get me a machine with 2x1GHz processors, 1Gb of RAM, and no hard drive. Another $125 or so for a 250Gb drive for the machine and another 250Gb drive to keep at home as a spare. Since the colocation site is here in town, I don’t need the ultra-reliability of the latest servers, RAID arrays, redundant power supplies, etc.

Ok, so I have to buy this machine, build it, and start setting up Xen. Then get my applications working on it. I’m also going to move this blog to “blog.xcski.com” and the gallery to “gallery.xcski.com” to facilitate moving them to the colo.
