I love maps… especially geeky ones.
Today was our first kayak outing of the year, timed very nicely with the first greater-than-90-degree day of the year. We hit the water at about 2, and got off at 6, stopping twice along the way (including once to visit with my friend Nick who was working on his sailboat). 6 miles in all, about 2 of which was pushing against the current.
The Hudson River is the defining geographic element around these parts. They don’t call it the Mid-Hudson Valley for nothing. Given that it is pretty amazing how few people really use the river for much. As we were kayaking along there were a bunch of things I realized that people who don’t spend time on the river don’t realize, so I decided I’d write them down for river neophytes out there:
- The River is Tidal, with Tidal delta about 3.5 in Poughkeepsie. Tidal affects occur all the way to Albany, where the river is dammed.
- From this, it follows that the River has saline content. Once you get a far North as Poughkeepsie, it is pretty dilute, though the area is still considered estuary, as it isn’t pure fresh water.
- The 3.5 foot tides also mean the river changes direction 4 times a day. The river runs almost as fast upstream as downstream (over 2 mph), as anyone who’s spent much time on a boat on it will tell you. The first time you realize the river is going backwards, it is definitely a shock, but as you understand it a bit more it makes sense.
- Whenever the river direction changes there is a very violent wave period for 30 – 60 minutes. I’m assuming the reason has to to with part of the water still making it downstream, while another part forces up. I’ve experienced it enough times that it is something very real, and becomes and interesting period of time to be in a kayak. I’ve tended to call this “the river fighting itself”, but I’m sure there is a better term for it.
- There are a bloody lot of giant Carp in the Hudson. I’m not sure where they come from, if they winter over, or what. But they are there, and this time of the year they are breading, so are seen quite a bit.
- The river flushes every year. From March -> June there is a ton of debris in the river (it seems to mostly flush out come late June). The debris is mostly water logged wood, which doesn’t do any harm to a kayak, but can do some nice damage to motor boat engines.
- There are Bald Eagles on the River. I’ve seen two now (one on July 4th last year), and they are pretty spectacular.
I’m sure there are other fun facts that I should add, but all of those seem to be bits that even people around here don’t know. If I think of anything else good, I’ll post it in future. If you’ve got anything else good, please stick it in comments.
Every once in a while I love to look through my spam folder just to see what makes spamassassin mark something really high. Here is one that got 49 points:
* 4.5 MIME_BOUND_DD_DIGITS Spam tool pattern in MIME boundary * 4.4 MSGID_SPAM_CAPS Spam tool Message-Id: (caps variant) * 0.1 FORGED_RCVD_HELO Received: contains a forged HELO * 1.5 RCVD_NUMERIC_HELO Received: contains an IP address used for HELO * 0.0 UNPARSEABLE_RELAY Informational: message has unparseable relay * lines * 2.0 HTML_MESSAGE BODY: HTML included in message * 5.0 BAYES_99 BODY: Bayesian spam probability is 99 to 100% * [score: 1.0000] * 4.5 MIME_HTML_ONLY BODY: Message only has text/html MIME parts * 3.7 PYZOR_CHECK Listed in Pyzor (http://pyzor.sf.net/) * 0.2 DNS_FROM_RFC_ABUSE RBL: Envelope sender in abuse.rfc-ignorant.org * 2.0 RCVD_IN_BL_SPAMCOP_NET RBL: Received via a relay in bl.spamcop.net * [Blocked - see ] * 3.9 RCVD_IN_XBL RBL: Received via a relay in Spamhaus XBL * [22.214.171.124 listed in sbl-xbl.spamhaus.org] * 2.5 FORGED_OUTLOOK_TAGS Outlook can't send HTML in this format * 2.7 FORGED_OUTLOOK_HTML Outlook can't send HTML message only * 4.5 MIME_HTML_ONLY_MULTI Multipart message only has text/html MIME * parts * 2.6 FORGED_MSGID_HOTMAIL Message-ID is forged, (hotmail.com) * 1.6 MISSING_MIMEOLE Message has X-MSMail-Priority, but no X-MimeOLE * 4.1 FORGED_MUA_OUTLOOK Forged mail pretending to be from MS Outlook
A few of these I’ve cranked up, like MIME_HTML_ONLY, as I don’t get any useful mail that is only text/html formatted. I still like that SA detects things like MIME_BOUND_DD_DIGITS.
I’m catching up on the mailing list for mercurial from the past couple of months. A couple really neat things in there:
* Mercurial Quick Reference Cards. These are really awesome. I’ve got to print out copies for all my interns on Monday, as they are just wonderfully done.
* Distributed Bug Tracking in Hg. This is based on the Bugs Everywhere concept. This looks really handy as a way of keeping todos in a source tree itself.
Ah, I love hg.
Well, it finally happened, the wireless driver got wedged on my laptop meaning I was done with wireless and suspend until a reboot. Final uptime was:
07:22:01 up 52 days, 18:27, 1 user, load average: 4.67, 13.07, 11.02
before I had to reboot. It did mean I could take all the kernel updates I need to, as well as update wireless drivers.
We got a donation to MHVLUG a year ago, which was a stack of 2U PIII servers that were being decommissioned from a company that one of our members worked at. We sold about 1/2 of them (at really nominal price) to get machines into eager members hands, and raise a little cash for MHVLUG events (like equipment for install fests). The servers had one flaw though, the power supplies liked to commit suicide if you unplugged them. You know this has happened if you plug the box in, and just hear a clicking sound from the power supply, and the machine won’t power on. The power supplies are an odd proprietary connector (though it breaks out to standard connectors after that) so direct replacement didn’t seem like an option. We swapped out PSU for those LUG members that got ones that broke, until we ran out. At which point everyone was on their own.
This hits home a bit, because I’ve got 2 of these boxes. 1 is serenity, which runs my wiki, but more importantly, my wedding site. That machine is fine. However, my xen test box did the suicide dive this weekend. Ominously, we are out of power supplies, and the site that we’ve got the wedding info on no longer has anything I could steal a supply from. This is not a good place to be in.
So over the weekend I began searching for power supplies again. While we’ll never find the crazy card interface that the current PSUs have, a little further research showed that any long 2U supply should fit in the case. After much time with google I came across Build to Order Servers. It appears that they had a 2U supply that would fit in the box, output 300W (the current one is 275W), and only cost $68. So between me, and the rest of nycccp.net, we ordered 4 of those units. That was Sunday.
Monday rolls around, and I get an email from the Vendor (and, as I found out later, a phone call at home). They are out of the supply I ordered, and won’t get more until July 17th. He does ask me where I’m going to be running the systems, because if it is in the US (where the power is reasonably conditioned), they’ve got an equivalent model which is $10 cheaper. He also asks about what my server board pins are, because the power supply is 20 + 4 pins, and most people order a 20 -> 24 pin converter with them. I respond back to him with output of dmidecode from my server board, plus the fact that it looks like I’ve actually got 24 + 6 pins. A couple hours later he sends me an image of a similar mother board (“is this what yours looks like?”), offering to custom mod the power supply pin outs for 24 + 6 for a small fee, and still being able to ship by Thursday if I’m ok with all of this.
That, ladies and gentlemen, is service. We’re talking about a total sum of about $250 worth of equipment here, and the folks at Build to Order Servers spent a lot of time making sure that I actually got equipment that is exactly what I needed. It’s rare that you see that now adays with all the crazy big box stores, so I am always astounded when someone really does give that much care for their customers.
Anyway, if you are in the market for anything Build to Order Servers has to offer, you should consider them. They went the extra mile for me on a small order, so I can’t imagine they’d do any different for you.
It appears that there is an AMD price breaking coming.
This is great news, as I had almost decided on getting another bare bones system over the weekend to use as a home media server, but now will hold off until after the price break. Hopefully by then the 500 GB drives will be a little lower as well, as I’m really digging the idea of 1.5 TB storage array on GigE at home.
