media Alice

Posted at 8:37 pm MST to Media

The people who did the "Tinman" take-off on the Wizard of OZ have a new miniseries showing on Syfy based on the Lewis Carroll Alice books.

The first half is showing today and repeated tomorrow, followed by the second episode.

This is not a low budget show: the cast includes Tim Curry, Colm Meany, Harry Dean Stanton, Matt Frewer and Kathy Bates.

The story line is interesting and the visual effects are decent.

I'm definitely watching the second half, tomorrow.

And I want to dig out my DVDs of Tinman and rewatch it.

weather New Slider

Posted at 9:40 pm MST to Weather

Wow! The new sliding doors between my bedroom and the deck are impressive. It's 0 Fahrenheit out and I just stood next to the sliding doors, and might as well have been standing next to the solid wall. There was NO chill coming through the door or its frame. There is no wind to speak of tonight, which might make a difference, but this is still very impressive.

Standing next to the new basement doors I can feel a little chill -- they aren't as heavily insulated. But they are still a vast improvement, partly due to being installed and caulked properly, which the previous dorrs were not.

This is excellent.

weather Block Heater

Posted at 6:51 pm MST to Weather

Yesterday was very cold and snowy. Last night the temperature dipped to 0 Fahrenheit, and this morning my foxy little car (now officially named Reynard) was very cranky about starting.

Tonight is supposed to be very cold again, so this evening I plugged Reynard in -- I had a block heater installed last summer after I bought him. It's a lot cheaper to invest in a block heater than to build a garage to shelter the car from the cold and wind on this ridge.

I have had block heaters in some previous vehicles, and liked them. Besides making the car easy to start on cold mornings, the warm engine starts giving heat to the cabin and defrosters a lot faster.

A trick I have used in vehicles without block heaters is to buy one of those utility lights that consist of a wire cage around a light bulb. Placing a hundred watt bulb into the engine compartment over night, preferably near the battery, can make a big difference on a cold morning.

There is a battery heater available for the Forester. I don't think I need both the battery heater and block heater, and chose the block heater because I like the extra heat it makes available for the driver. If I were going up into the ski areas, I might consider adding the battery heater, but I would need to rig a way to plug both heaters in.

Corporate housing for any gig in a really cold climate should include covered parking, so I really only need the heater here.

tech Stuffing for Breakfast

Posted at 12:15 pm MST to Technology

It's national appliance-using day

So far today, I have baked squash and pumpkins, and pureed the pumpkins (food processor), roasted potatoes, made my usual stuffing (stand mixer and food grinder), put the turkey in to roast in my fancy oven (I'm using Alton Brown's recipe, same as last year) and made stuffed celery.

Later today, I may make some pumpkin pies and some eggnog (which will use the blender).

The dishwasher is on it's third load, and I've washed a bunch of stuff in the sink...

I ate some of the stuffing mixture -- bread, ground cooked meats and veggies, and broth -- for breakfast. The rest of the stuffing is baking in a corningware next to the turkey.

Ounce for ounce, I think the most expensive item on my menu today is the stuffed celery I'm nibbling on as an appetizer. I was able to find goat cream-cheese this year but it costs about five times as much as cow cream cheese. But having proper stuffed celery makes it feel like Thanksgiving.

Soon I will take the turkey and stuffing out of the oven, make gravy, and reheat the potatoes and squash.

Then I will eat. Lots.

Spending a day cooking makes a nice change. I've been on a paying gig since last Wednesday and also worked on some computer side projects, so this has been a very busy week.

misc Plumbing

Posted at 1:45 pm MST to Miscellaneous

My great plumber -- James Johnson of Nautilus Plumbing -- was here today to fix some small things.

The kitchen faucet was binding in the hot water lever and leaking slightly around the base of the spout.

I got a snazzy new shower-head gadget at Costco a while back that needed to be installed.

And the bathtub has been draining slowly and sort of burping air up through the water that is draining, which didn't seem right.

In 2002 I partially remodeled my bathroom. As part of the changes a company called Master Plumbers installed vinyl inserts to cover up my ugly old tub and deteriorating tile with the icky grout, changing the tub stopper mechanism in the process. It turns out they didn't remove enough of the old stopper mechaism and over time it had fallen down until it partially blocked the drain. James was able to clear the blockage and remove the offending components so the problem should not recur.

When I made the changes in 2002 I had James rig up the shower so I had both a flow control regular shower head and a hand shower head available. That has worked OK over the years, but the (slightly kludgey) mechanism for switching between the two heads never fully sealed -- whichever head was active, there was still a little flow through the other one. The new shower gadget is a single unit that is designed with both types of shower heads, with levers and seals to direct the flow as desired, or temporaorily turn off the flow completely at the shower head with changing the temperature and flow settings of the faucets. This should be nice.

But I think I'm going to stay away from Master Plumbers in the future -- not difficult since I have had no contact with them since 2002.

tech Reconnecting ClearQuest to DB2 after changes

Posted at 1:22 pm MST to Technology

When changing the password of the DB2 database itself (as set in the CQ Maintenance tool), it is not enough to create a Connection in the Maintenance Tool that uses the correct password. Even though the Connnection succeeds, the other CQ
tools will not be able to access the database, and the connection will act as if the new password value is not sticking.

After creating the connection successfully in the Maintenance tool, Select Schema Repository->Update->Current Connection and set the new password again, then apply the changes. At this point the schema repository will be accessible using the ClearQuest Designer tools.

Then update the user database(s) if the password changes affect them too. The usual Database->Update User Database Properties tool in the Designer seems to be effective once the schema repository is connecting properly.

This update requirement is documented for Options changes. It just isn't clear in the IBM docs that it applies to password changes, too.

tech DB2 settings

Posted at 11:51 pm MST to Technology

After a lot of thrashing with DB2 partially working, I finally dug out some DB2 error codes that were googleable.

SQL1084C Shared memory segments cannot be allocated. SQLSTATE=57019

SQL5043N Support for one or more communications protocols failed to start successfully. However, core database manager functionality started successfully.

The first problem, which was preventing runing of most of the dtabases on ykchaua itself, turned out to be shared memory limits inthe OS.

Running "sysctl -w kernel.shmmax=2147483648" seems to have made DB2 runnable on the server, but may be overkill. Checking some old backups, I found a section in sysctl.conf like:

kernel.shmmax = 1610612736
kernel.sem = 250 256000 32 2048
 kernel.msgmnb = 65536
 kernel.msgmni = 16384
 kernel.msgmax = 65536
 kernel.shmmni = 4096
 kernel.shmall = 3774873

The existing values (for the values other than shmmax are) :

kernel.sem = 250     32000   32      1024
 kernel.msgmnb = 65536
 kernel.msgmni = 1680
 kernel.msgmax = 65535
 kernel.shmmni = 4096
 kernel.shmall = 2097152

So I added the block back into the new /etc/sysctl.conf. And this time I commented the changes (which were probably made automatically when I first installed DB2) as DB2 related, so they are less likely to get lost again in the future. Having sysctl.conf set up should make the fix last across reboots.

The other error message I was receiving turned out to be because of a missing entry in /etc/services -- another case of updates stepping on config files.

After appending "db2c_db2inst1 50000/tcp # DB2 first instance" to /etc/services, DB2 seems to be running cleanly on ykchaua. Finally.

And....

My applications in the Windows images are able to connect... technically. I was able to configure the connections without error messages, But I can't seem to login to the apps, and the error messages are not being helpful.

tech WICD

Posted at 1:07 pm MST to Technology

In my ongoing quest to get samba working again with the vmware images, I realized that part of the problem may be that the network was not getting set up soon enough at boot time. (Samba worked for a couple of days after I get it set up, but I'm nt sure it came back after the next reboot.) The vmware images were coming up with their network connections in strange states after the main machine rebooted, which seemed suspicious... or at least unhelpful.

The NetworkManager tool that comes with Karmic Kubuntu was not setting up the link until after I logged into the X window system. This could be a problem for samba because the authentication module that wanted to talk to the Active Directory server could not reach it until networking was running and vmware was up. Getting the networking stack to be active as soon as possible after boot would help the handshaking initialize properly.

The lack of a working network at boot time may be making DB2 unhappy, too.

I had given up on Network Manager completely in previous OS versions. But that meant I needed to manually edit the /etc/network/interfaces file whenever I needed to use the wireless connector in a different environment -- at the office, or a hotel, for example.

I hoped there was a way to make my wireless connection more flexible, even with the vmware subnet bridged off it. One of these days I want to get wired ethernet run to the livingroom and bedroom from the study where the DSL modem and router live, but for now I need to use the wireless connection for things it's not really configured for.

A bit of googling suggested that a tool called "wicd" would provide connect-at-boot, and also the flexibility to support some of the fairly strange networking requirements I have. I haven't tried a wired connection with it yet, but the wireless one seems to be doing what I wanted it to.

So far, so good.

Next step, get the samba permissions working again. Then get DB2 up. Then do the development and testing I'm really supposed to be working on.

tech VMWare 202

Posted at 12:58 am MST to Technology

I refreshed the kernel modules (which should have just reinstalled the same stuff) and upgraded VMWare server to 2.0.2 and updated the vmware tools in all the guest OSs. VMWare seems to be working again now.

Samba permissions are still flaking out but I'll deal with that after I've slept.

I noticed when I was refreshing the kernel modules that even though I used an i386 installation disk, kubuntu seems to be using the x86/64 kernel modules. If I have any more problems, I should proably try to force it over to the i386 versions. I'm not entirely sure how to go about doing that safely.

tech Gah

Well, drat. Samba stopped working again, and now vmware has decided it doesn't like the current version of the kernel, which it has been running with happily for over a week. The samba problem may have been the first sign that vmware was breaking down.

So annoying. One step forward, two steps back.

I just got the local laptop version of this blog working again (replicating the paths at my ISP is a little messy). And manually edited kmailrc to get signatures added to my emails automatically - I think the app that changes kmail settings is flakey in the latest kubuntu.

But I don't see how either of them could have broken vmware. I updated some stuff earlier, mostly pieces of the cups printer controller app. Don't see how that could have broken anything either.

Sigh. I wish vmware support for new linux versions was less clunky.

Time to google.

misc Doors

Posted at 6:36 pm MST to Miscellaneous

My new doors were finally delivered and installed today.

Dinah Kitty was not happy, but she seemed less upset than she would have been in the past. I think she may be getting a bit deaf in her old age, so she doesn't notice people moving around the house as much as she once did.

The new sliders to the bedroom deck have a full inch between the double panes. The old doors were technically double paned, but had only a fraction of an inch between the panes. The screen door built into the unit actually is usable. And the new frame is vinyl with heat flow breaks. So my bedroom should be warmer in winter and cooler in summer.

The old doors were not original: the ones that were installed whe I bought this house were single paned and had flimsy aluminum frames that rattled in the high winds we get here.

The French doors to the basement aren't as insulated as the sliders, but they close and lock, which the old ones didn't since the landslide last summer, and they are very well caulked, which the old doors were not.

I suspect that some of the mice were getting in through the gaps around the old doors. I hope that in addition to being far more weathertight (which should improve heat bills) the basement is also a bit more rodent-proof.

I should probably invest in some carbon monoxide alarms now that the basement is not constantly ventilated, just in case. There have been radio ads saying it is now legally required to have them. I hope the new ones last better than the last time I put a CO alarm in the house. It was more trouble than it was worth.

If they are still offering tax credits for weatherization next year, I may see see about replacing the basement windows with insulated double-paned units.

tech Enable Local Display

Posted at 2:36 pm MST to Technology

Newer versions of Ubuntu have the X display locked down so that other userids cannot access the gui, plus there is a bug in 9.10 that makes it even less likely to work.

To fix the bug, I created a file. etc/X11/Xsession.d/60x11-localhost and filled it with contents I found at the online Ubuntu bug report 276357. It turns out that this file existed in 9.04, and the contents in my saved etc tree from before the upgrade matches. Which is encouraging.

Also useful:

emgrasso@ykchaua:~$ echo $DISPLAY
:0.0
emgrasso@ykchaua:~$ export DISPLAY
emgrasso@ykchaua:~$ xhost local:db2inst1
non-network local connections being added to access control list
emgrasso@ykchaua:~$ su - db2inst1
Password:
$ DISPLAY=:0.0;export DISPLAY
$ db2cc

That gets me into the DB2 Control Center GUI, but DB2 itself is throwing some weird errors when I try to start up the database.

This is still the version 9.5 I restored from my backups -- I needed to install a down-level version of libstdc++ (libstdc++5_3.3.6-17ubuntu1_i386.deb) to get it to run at all.

I have downloaded db2 9.7. I'm going to google for the errors I'm seesing. But I think my next step is to uninstall 9.7 and see whether 9.7 behaves better.
