I had planned to install a new faucet for my kitchen sink today, but it's proving more troublesome than expected. I'm going to delay this for a few more days.

Plumbing... I have to replace the in-commode valve. As it is, to get the tank to fill I have to shut off the feed valve so that the in-tank valve will open. Apparently, relieving the pressure in the line between feed and in-tank opens something in the in-tank valve and everything flows. Of course, this comes with a very disturbing vibration of the pipes in wall at the first half turn of the feed valve and can not be very appealing to my neighbors at 3AM.

Much luck with yours. :-)

I finally have a new stable version of Retro ready. This includes the new Scheme and updated HTML5/JavaScript implementations of the virtual machine, updated documentation (fixing some significant errors in the VM spec), more examples, improved libraries, and an image file with a new combinator and some minor cleanups.

The source can be downloaded at http://s3.retroforth.org/download/11.x/retro-11.1.tar.gz

Android users can update or install via the market at https://market.android.com/details?id=com.forthworks.retro for a stable release or https://market.android.com/details?id=com.forthworks.beta.retro if you want to use the latest development builds.

An updated Chrome extension and app will be appearing within the next couple of days. I'd try to get it out sooner, but some of the files I need are only on another machine I can't access until Monday.

Trying to find fix bugs in some Scheme code. This is proving different enough from Common Lisp to make things harder than I expected.

I've uploaded a beta of the second incarnation of Retro for Android devices. This isn't finished yet, but has the new console code, multiple project editor, and user-adjustable VM settings. It should also be more efficient in terms of battery usage, as the VM can be manually paused, and should now be mostly suspended when waiting for input.

The new .apk is at http://bit.ly/tWLFng

This week's puzzle on themastertheorem.com was easy, though one of the words in the solution was created specifically for this puzzle. I hate it when this is done; it makes it harder to be sure you've solved the puzzle correctly.

Despite this, the puzzle was pretty easy. A classical four-square encryption, and the keys were provided in the article text.

Having worked through 30 of the puzzles so far, I decided to write a library in Retro to deal with encryption and decryption using the classical techniques M likes. I have a few (ceaser, rot13, pigpen, tapcode) done, and a couple more (keyword, four-square) nearing completion. This should make future puzzles more straightforward.

I've been finding Bootstrap 2.0 from Twitter to be very useful. Saves a lot of work in terms of getting my web applications and site layouts working properly.

Over the last four days I've updated the development site (http://rx-core.org), blog (http://rx-core.org/dev/corpse), irc log browser (http://rx-core.org/dev/rancid), the HTML5 implementation of my VM (http://rx-core.org/demo) to use Bootstrap. I've also incorporated some elements into the documentation page CSS to improve formatting in a few areas.

We've been doing our year-end inventory at work. I'm looking forward to this being over (hopefully by the end of next week), so I can get back to my hobbies. When I leave here today I'll be at 46 hours worked, with another 13 or 14 to come tomorrow.

On Saturday and Sunday I'm taking my kids on a surprise trip to Lancaster, PA. I'm not sure what all we'll do while there, but I'll at least be away from work.

Have a safe trip, Charles. Best wishes for 2012.

I've fixed all of the major bugs in the Scheme code. It passes the core test suites, so apart from being slow, it's capable of loading and running a standard Retro image now. Still plenty to do (no file I/O, saving of images does not work), but it's a solid start.

Preparing to enjoy the last of one of the few white teas in my collection. As this one is now unavailable, I'll have to look for a substitute when I get ready to do my next tea order.

I've disabled anonymous bug reporting on my repositories after having one of them get heavily spammed. I hate having to do this, even though the bug tracker wasn't getting much use.

Taking a break from the Chinese teas. It's taken me a while to learn to brew sencha without making it bitter, but now I do ok with it. I may take some of this home tonight and do an ice brew.
