Too long since last post [Nov. 19th, 2009|09:03 pm]
I've been so involved with writing and test-solving Hunt puzzles that this blog is getting ignored, but I figured I'd write something.
  • I had enough time to play in the /dev/null/nethack tournament at the start of the month, but I haven't played this week. I did manage to play a few serious games, one of them just getting past the castle before YASD, and I completed the Grue challenge, the ZAPM challenge, and this year's new challenge within the first two games. I never seem to encounter the level for the Pacman challenge, and the KoL challenge is broken this year. The wish to activate the ZAPM challenge came from a water demon that popped out of a fountain while I was trying to uncurse stuff. At some point I should post a recap here and all my badges for accomplishments over the last 4 tournaments.
  • My prizes for yet another year of alsoran status in the Google U.S. Puzzle Championship arrived yesterday. It was two ThinkFun puzzles, the Rec-Tangle puzzle (which I solved in about a minute) and the 36 Cube (which I didn't start playing with yet).

SUMS 2009 puzzle details [Sep. 5th, 2009|07:53 am]
[Tags|]

OK, it appears to be over now, as far as prizes are concerned. 6 teams (4 with Australian members) have solved all the scoring puzzles, and with remaining puzzles worth at most 4 points each, the best any of the other teams can do is tie the 3rd & 4th place Australian teams, which would leave that team 5th on tiebreaker by last solve time.

Although I will spoil some things below, a lot of it is already pretty well spoiled by the official hints.

SUMS 2009 Puzzle Hunt [Sep. 4th, 2009|09:19 pm]
[Tags|]

Woot! Together with the same group I've been solving a lot of these hunts with, we have won the inaugural Sydney University Mathematics Society Puzzle Hunt. The team is no slouch, pretty much identical to our winning MUMS team earlier in the year, but with the addition of Corey Plover (who we lost to puzzle construction for MUMS after it being due to him that we started doing Australian events in the first place). We're also a portion of the team that won the MIT Mystery Hunt this year.

As of the release of hints at noon Saturday Sydney time (10 PM Friday US eastern time) nobody else can pass our score of 99 points, and only Tweleve Pack can tie us. We solved all of the puzzles within 5 hours of their release except Poetry Makes Character Sore, which [info]dalryaug  figured out in the 47th hour, and the non-scoring meta, which we got just shortly after solving Poetry.

I am not going to go into great detail about the puzzles now, as some teams are still competing for the remaining prize positions, but I will say there were some very nice puzzles and a couple clunkers. I think I enjoyed this hunt more than any of the MUMS or CISRA hunts of the last few years. One of my teammates described one of the puzzles as the one he wishes he had written for Mystery Hunt 2010. I will post details about the puzzles when the hunt is over, or at least after the prize rankings are all set.

So now we can solve the Labor Day Extravaganza without worrying about SUMS. (There's the Harvard hunt which starts an hour later, but I am personally skipping that one. A man can only do so many puzzles.)

At con [Jul. 8th, 2009|03:45 pm]
[Tags|, ]

I arrived at con, after navigating a maze of sidewalk closures in the 4 blocks between the light rail station and the hotel.

I am on the 27th floor of the hotel, which means that if there weren't these other two huge towers in the way, I would be able to see across a huge part of Baltimore:

Summer finally arrives in New England [Jul. 4th, 2009|04:49 pm]
[Tags|, , , , , ]

While most of the country has been sweltering in 90-100 degree heat for weeks, in New England we have overcast skies, rain, and highs in the 70s or even 60s for what seems like a month. But we've got some good sun and warmth here for the 4th of July.

Meanwhile, what have I been doing?
  • Oh yeah, rain. People have been having a stupid number of accidents during evening rush on 128, so I have been getting home up to an hour later than usual. This has been taking time away from other things I'd like to be doing. Together with the general heavy load at work, it makes me feel like I need a vacation. It's a good thing I have one...
  • The NPL convention is just around the corner, of course, and I have had my arrangements made for a while. There is clear weather in the forecast, with some chance of a passing thunderstorm to interrupt an otherwise rain-free con. And I continue to work on Enigma puzzles and try to build up a string of completes.
  • I haven't had a lot of time to work on Math Magic but I did manage to put my name next to one miscellaneous achievement, as well as two "none"s where I showed particular results weren't possible.
  • On Ed Pegg's site I saw the link to Al Zimmermann's Son of Darts contest sometime last month. I have some programs running for this but I am not devoting a lot of my time to it right now. There is a whole year to work on it. I am running some fairly lengthy searches to try to get some good results for all the cases; I expect to have 86 points and change when these are done and my initial results for all the cases are posted, which still leaves me needing a breakthrough in better search techniques to have any prizewinning potential.
  • The external monitor I use with my laptop died recently, and seeing how it was a 5 year old 17" LCD, I followed the old tradition of upgrading to a much better monitor (in this case, bigger) for about what I paid for the last one (a 23" widescreen, which adds both in area and pixel count approximately 50% more length and a little more height). Of course, at the con, I will have to make do with the laptop screen alone, but con is mostly not about using computers.
  • I went to Salem Willows and got in a good session of pinball today, scoring replays on Nascar, No Good Gofers, Attack from Mars, and several on Funhouse, eventually setting a #2 high score on it at 27 million. There were tons of people in the park enjoying the first nice summery weekend we've had all year, and not the largest crowd I have ever seen in the arcade but still a good number of people in there. They have a nice setup with about 16 pinball machines this year, close to the most I have ever seen in there, though for the most part they are the same ones they have had there in years past. There were a few broken ones; their tech is probably out enjoying the nice weather!
  • Oh yeah, and though I was rather slow about it, I finished the recent meta-puzzle in P&A Magazine. I didn't find the hidden contest yet; maybe during con travel I can look for it.

2009 USPC wrapup; Di-Agony [Jun. 28th, 2009|06:55 pm]
[Tags|]

The results for USPC 2009 are posted, and the 155 points I was unhappy with ended up at 21st place, but only 20 points from 13th, so I was only 1 puzzle slower than many of my recent performances. All of my submitted answers were correct.

[info]nickbaxter  commented that only 4 people solved DI-Agony during the competition. The stats page shows that nobody else even submitted an answer, making it also the only puzzle that nobody got wrong. From his own report we know [info]motris  solved it, and I did also, which leaves just two others out of the hundreds of entrants. I wanted to comment in detail on it, but with so few people having solved it, only behind an appropriate spoiler warning.

USPC Post-Mortem [Jun. 23rd, 2009|09:45 pm]
[Tags|]

Having looked over the puzzles I didn't solve during the competition, and having solved most of them, I really think I made some bad choices in puzzle selection, some of them ones I should have known better about.  I don't know if anybody else will benefit from this, but hopefully I read this before next year's USPC and make better choices because of it.

USPC [Jun. 20th, 2009|04:02 pm]

Just ugly. 155, with a 90% done Yajilin that could have made it 180 if I was a little faster.

I did the square counting first (my answer of 152 seems to be popular), then looked at the big point ones and did diagony and suDUOku.

Then I went from the front, doing the ones I could do quickly (or quickly for their values) and ended up on the yajilin at the end, not fast enough.

What Joe's Doing [Jun. 14th, 2009|11:45 pm]
[Tags|, , , , ]

I've been very busy lately doing all sorts of stuff:
  • W**k is a heavy load lately, but let's not burden the blog too much with it. Suffice it to say that I am not putting in more hours but I'm being called upon to do a heck of a lot during the hours I am there.
  • Mystery Hunt is chugging along. Some of my puzzles will be in next year's Hunt. Probably more than in the 2008 Hunt, but we are a smaller team than Palindrome was, so this is to be expected. Of course I can't say more now.
  • There is a whole bunch of interesting stuff at MathMagic this month. I have some contributions on one problem and one I need to properly write up on another.
  • The US Puzzle Championship is next Saturday. There is still time to register. I do not expect much of a difference in the results from last year, but I will participate as I have done the last 10 years or so.
  • It seems all my friends are throwing parties for one reason or other this month, and I am attending some of them. And the NPL con is in Baltimore in just a few weeks.
  • Kingdom of Loathing stuff )

Logic Masters results [May. 10th, 2009|08:45 am]
[Tags|]

Between 500 turns of Kingdom of Loathing in the morning/early afternoon because my character ascended today, and going to Eric's house in the evening, I managed to fit in the German puzzle championship as part of my prep for the USPC.

That is a little more encouraging that some of my recent performances, but continues to show why I should not be expected to show up on a WPC team soon -- slowness. 19th in the international section and a score that would have been 9th among the Germans, so I would have failed to make their team much as I am too slow to make the US team these days. At least I didn't get anything wrong. I could have scored a little better if i had been more selective instead of just doing the test front to back, but I don't think it would have made a huge difference unless I completed the maze #20.

I don't see any of the familiar American names here, so apparently the others either didn't compete or didn't bother to submit scores, except for the one person who registered as "No Name" and placed 6th internationally.

Turkzeka #2 came out just before I left for Eric's, and I am befuddled by it.

May, a month of puzzles [May. 2nd, 2009|07:30 pm]
[Tags|, , ]

Every month is a month of puzzles with me, but here's some puzzle news:
  • My team, plugh, finished up the CISRA puzzles last night, solving the last one 2 days after the next-to-last one to finish 4th in the non-prize-eligible division.
  • Turkzeka started today. The first puzzle is still available at full value if you'd like to join.
  • Logic Masters, the German puzzle championship, is next Saturday.
  • The Washington Post hunt is Sunday, May 17th. I'm not planning to attend.
  • And for next month, the USPC is June 20th.

Spring [Apr. 18th, 2009|05:31 pm]
[Tags|, , , ]

It's finally spring in New England, and I celebrated by staying inside and solving puzzles. Well, for a little while. I went out and did some work de-winterizing the yard in the morning, came in for lunch and then did OAPC 4 after they finally got it started. As with most such events that I have participated in for the last while, I finished with a result that is probably decent but below the US WPC team by a bit.

Then I went out and did some more yard work, ripping out some sod from last year that didn't take and seeding the area instead. This was interrupted early on by some emergency fence repair as my back-side neighbor's dogs had knocked out the last board on the end of the fence and one of them came wandering into my yard and wanted to play. The neighbor's away on vacation but I contacted his friend who's house-sitting and dog-sitting for him and we got the dogs corralled and the fence repaired.

I finished 9 of the puzzles in the P&A that came out last weekend, but I am lost as far as solving the meta - hints should be out today, so I'll pick it up again. I've also been working on Winston Breen's Puzzle Party in recent days. The puzzles are pretty easy, but it's for children - bright children, but children nevertheless. A week from tomorrow night, the rest of CISRA begins. And I have a few Mystery Hunt puzzles in development; hush-hush on those, of course.

Woot! [Apr. 4th, 2009|01:25 pm]
[Tags|, , , ]

Mystery Hunt progress slowed over the past week because a bunch of us were doing the MUMS puzzles, but we won! We lost our original Melbourne contact Corey to puzzle design, but [info]sin_vraal  had a friend in Melbourne who we called on to go find the mystic bananas when we figured out last night where they were.

I'll be at the Boston crossword tournament tomorrow as a noncompetitor. Hope to see many of you there!

And of course I am spending time solving RPO's annual presents in the April Enigma.

More Stuff Joe's Doing [Mar. 7th, 2009|06:28 pm]
[Tags|, , , ]

In my recent post I omitted one of my February activities. Cliff Johnson has been working on The Fool and His Money, the sequel to The Fool's Errand, for quite a long time, and he has finally delivered a free teaser with a few of the puzzles. Recommended for old-school wordplay and puzzle-game fans. I solved the puzzles in the teaser.

In addition to the one I wrote up here, I have been solving the Kenken varieties posted by [info]motris . (But since they are more normal and able to be presented in text solutions, I have been writing them in white-on-white comments.)

There was also the Microsoft Puzzle Hunt last weekend, and I have been working on some of the puzzles from it.

What is Joe doing? [Mar. 2nd, 2009|12:29 pm]
[Tags|, , ]

I've been up to quite a lot since my last post.
  • I submitted a Ralf for the Enigma that gave Crax a good laugh. Look for it next month.
  • I got my laptop fully working again (see last post). The inverter turned out to not be the problem, but actually the backlight itself, which was a much more daunting job to replace, mainly in the part where I have to solder the backlight wires onto what are just tiny posts on the end of the backlight. This required several tries. I had tied the fragile bulb to a plastic part of the frame that it rests against anyway once it is installed to help hold it in place, and ended up also temporarily tying the wire there once I had it looped around the post, while I worked on the soldering.
  • I've been working with my teammates on theme development for next year's Mystery Hunt. I can't say much about it, of course, but stuff is happening.
  • I skipped the ACPT again, as it doesn't serve the purpose for me that it did when I started going.
  • I went to Matt Stone's party Saturday, and learned 3 new games: Dominion, Aquadukt, and Chicago Express, but didn't win any of them.About the games )
  • We had a very small local NPL get-together Sunday for non-ACPT-goers. I taught La Do La Li/Ti and Sue++ the classic game of Anagrams, and we played some other games and laughed at the Scrabble Junior Cheez-Its. Brief review of the Cheez-Its: Pretty much like regular Cheez-Its, but the same technique that is used for pressing the edges is used to make letter shapes in the interior of each cracker. This makes them denser and less puffy than regular Cheez-Its, and I think it makes them taste and crunch more like Cheese Nips. A number of the crackers were broken off on one side, along the edge of the letter. The Scrabble Junior component is a miniature gameboard printed on the back of the box, offering suggested words and some pre-printed letters, along with a set of rules for playing a Scrabble-like game. We chose not to play the game, but I pulled handfuls of 5-7 crackers from the box and tried to spell my best word from them before eating them, usually failing to use all the letters due to an overabundance of vowels.

Lappy is down [Jan. 30th, 2009|10:27 am]
[Tags|]

I experienced a problem, just twice until last night, where my laptop screen went dark. The backlight had gone out, just as it does when I close the lid, but a dim image was still visible on the screen. The first time happened early this month, and the second time was during the Mystery Hunt when some teammates called me over with worried voices to check out what happened with my laptop. In both cases, closing and reopening the laptop caused it to come back on. I had also noticed, over about the same period of time, that when the screen came back on from being blanked due to idleness, it often appeared dim and pink for a short while before reaching full brightness.

Last night, the offending part failed in full. When the screen darkened and I repeated the close-and-open procedure, it only stayed on for a short while before going dark once more. After a few cycles, it was only staying on for a few seconds. I am glad this did not happen during the Hunt.

Miscellaneous Hunt Stuff [Jan. 24th, 2009|08:25 pm]

Somebody (whose post has scrolled off my friends page) linked to this kakuro-sudoku puzzle over Christmastime, and I read it and printed out the puzzle after I returned from my travel. Just before the Mystery Hunt started I finished the puzzle. Took me a LONG time.

Behind this cut, the remaining comments I have on Hunt puzzles now that I can look at all of them and their answers on the web site. )

Mystery Hunt: Supplies [Jan. 21st, 2009|07:10 pm]
[Tags|]

I supplied more equipment to my team this year than I ever have before. I suppose this is natural, being one of the few locals and even fewer local Hunt veterans on a smaller team than I have been on any year except the year EC Come EC Go and IHTFP were both so small that they merged. Still, the list of what I brought in, a small trunkload, is staggering:
  • Color laser printer
  • Laptop with external mouse
  • MP3 player
  • Digital Camera
  • Flatbed scanner (that ended up not getting used since there was another one available)
  • 3 power strips, and all the cables to connect and power the above equipment
  • Erector set
  • Pre-constructed spaceship made of R-C car, erector parts, and playing cards, and the R-C controller, 2 dice for it to shoot, and batteries
  • Box of plastic nametag holders
  • Set of colored pencils
  • Scissors (This was a late addition and a fortunate one; nobody else brought scissors)
  • Scotch tape
  • One of those clipboards that opens up for you to store papers and stuff inside, with 3 twist-erase pencils, a large eraser, and a pen
  • A pad of paper and a pad of graph paper
  • A little food and 2 12-packs of Coke
  • Folding cart to help haul the stuff in
And on top of this, I ended up contributing a Croatian magazine, some maps, and a car manual to the scavenger hunt (the first of which I picked up from my home Friday night; the others were already in my car).

Except for the MP3 player, scanner, their cables, and the camera's cable, all of it was used. If you knock out the spaceship parts, this is a good starting point for a team supply list. Obviously you will want more of some items.

Somehow I managed to come home with almost all of it save for consumables, the only losses being one twist-erase pencil and the plastic cap for the container of colored pencils.
