Jython 101

Inspired by Joe Gregario, I thought I'd take a gander at Jython.
The proposed JythonSprint seemed to suggest that unicodedata was required, so I thought I'd have a play and maybe even contribute something. We'll see.

So, grab the main trunk from subversion and off we go. TDD all the way, as much as possible. Are you sitting comfortably? Then I'll begin...

Step 1 - create an ant.properties file. This is in .cvsignore, so no worries about clashing with anyone else's settings. Straight off the developer guide.

build.compiler=modern
debug=on
optimize=off

Step 2 - build it using ANT.

Step 3 - make it accessible. I don't have jython on my machine already, so I take the dirty approach.

sudo vi /usr/bin/jython
#!/bin/sh

export JYTHON_HOME=/home/jabley/work/workspaces/main/jython
exec java -Dpython.home=${JYTHON_HOME}/dist/ -jar ${JYTHON_HOME}/dist/jython.jar $*


Slight tweak from the development guide, and yes, I'm using Eclipse.

sudo chmod 755 /usr/bin/jython

Now see what it looks like:

jython
*sys-package-mgr*: processing new jar, '/home/jabley/work/workspaces/main/jython/dist/jython.jar'

Cool.

Next run the tests.

jython dist/Lib/test/test_unicodedata.py
Testing Unicode Database...
Methods: 38ef24ef104d52e24f9b7c942676c6961f9233cc
Traceback (innermost last):
File "dist/Lib/test/test_unicodedata.py", line 84, in ?
ImportError: no module named unicodedata


That's expected. So I added a class org.python.modules.unicodedata and added an entry in org.python.modules.Setup to have a unicodedata module. I'll probably go back to the class name and maybe create it's own package longer-term, but that's the simplest thing for now. Tests again.

jython dist/Lib/test/test_unicodedata.py

File "dist/Lib/test/test_unicodedata.py", line 62, in test_unicodedata
AttributeError: class 'org.python.modules.unicodedata' has no attribute 'digit'

I seem to recall reading about some script that will generate stubs for these things - gexpose.py? I'll have a look, but otherwise it looks like my next step will be implementing stubs for the required methods and see where the tests fail next.

Roaches in the sun

Managed to head up north for a day, hooked up with the Banks, Laurie and Dutch. Cracking day, too hot really (and this is February!).

Mooching around under Inertial Reel discussing who had climbed it. Martin Dearden was just next to us, apparently enjoying being the subject of our historical wanderings when we tried to remember who it was that had taken eight years on it. Mind you, that's positively fast given that I first tried Stefan Grossman eleven years ago, before DB had done it. I came close six years ago, and haven't really been back. There's a long-term goal!

Did a bit, felt a bit fat and not moving well, I think I was a bit tired from introducing the weight belt back into the training programme. The Banks did well, getting Teck Crack Superdirect third go or thereabouts. I couldn't get my foot on the starting hold - bit of flexibility work required maybe!

Backed off Stretch and Mantel - I can't mantel and it was a bit high. Then puntered about on Calcutta Buttress before team effort on the world's hardest 6a+ slab. Andy came close; Adam Long complained about old boots not being up to it, Fiona crimped like a beast but couldn't quite get it.

Flashed Stretch Armstrong then it was time to go. I didn't really do much, but had a good day out with the guys. On the way home, Al rang and said it was OK for me to stay over, but I was already halfway home. Will get an overnight pass properly sorted out for the future.

Tool User 2

Callum has worked out how to open the child-proof locks on all of the cupboards. I am now locked into the sort of security patch / break / patch cycle that Microsoft administrators must enjoy living. Previously, he had discovered that pulling really hard would get the sweetie cupboard open, but now he's found that the sweetie cupboard is oriented one way, and the biscuit cupboard is oriented another, and he just has to slide it open and press to make sure the latch doesn't engage.

The fittings are oriented at 90° more due to my ineptitude at figuring out how to install them without any instrucions, rather than any conscious effort to prevent them spotting any usage patterns.

Tool user

Connor's noticed how to use Callum's toilet step to stand on and reach stuff. This currently equates to emptying the cutlery drawer when he can! This is a bit earlier than Callum started to do this, but then Callum didn't have the step until we started weaning him off the potty, which would have been when he was 2 ¹/₂ or so.

Where's Baby?

(to be said in a thick Yorkshire accent - I'm teaching Callum Northern).

Had the twelve week scan today - all looks fine at this stage. Exciting, and I can announce it to the world, both here and in publishing ages old drafts.

So here's a little ego experiment for me. I'm not sure how many of my mates read this blog - some have asked about it.

I'm also curious as to how many are au fait with Atom and RSS. Well OK, I don't expect them to be that au fait with RFC 4287, but they maybe have come across the general concept. Plus I'm tight (did I mention I'm from Yorkshire?) and want them all to ring me rather than the other way round!

Big boy

Starting Callum on no night-time pants - we'll see how it goes...

It begins again

The night before we go on holiday with my folks, Al shares that there was a blue line on the pregnancy test. Here we go again!

Development update

Took Callum swimming today. He's coming on lots and we ought to think about swimming lessons soon. I think he could take a more structured approach OK. He's happy to try swimming on his own with the armbands, but struggles against the current in places!

Connor's volcabuary is coming on. I thought after I got back from Font that there'd been a leap, but I wanted to document it:

Hiya

Standard phone greeting.

Bye

Standard phone sign-off.

Sweetie

Used when rattling the cupboard door.

Share

When trying to get a toy back off Callum.

Sha-sha

Shower, but can't quite pronounce it.

Mama

...

Daddy!

...

Me!

"Who wants to be first in the bath?"

Yes!

"Would you like some pasta, Connor?"

Font trip 2006 retrospective

So, this is in effect a post-project review. Sad. Next time, I'll have a Gant chart! Anyway, in no particular order of priority:

• I was strong - should have got more done.
• I had real problems transferring that strength to the rock - getting the power onto the road as it were. That felt like a real technique thing - the majority of training for this trip was done on my board, or doing deadhangs and ladder work. So need more variety generally. Well, I already knew that, but it's a bit hard to get living in Hampshire!
• Preserve skin, rest properly.
• Take rest days.
• I don't live in Sheffield and do twenty hours climbing a week anymore. So don't get sucked into climbing with others that do! Further to that, I am only doing around five hours climbing a week. To get the stamina to do lots of climbing, you need to climb lots. No secrets, just hard work and time.
• Specificity! My training mainly consisted of doing thirty problems with two minutes rest. So I was fairly well primed for doing circuits of that length, but not a full day of all-out bouldering.
• Session peak. Doing twenty problems like that is not a good warm-up for climbing anywhere near my limit. Doing a short warmup and making the seventh problem that I do at my top-level would have been a better fit.

So major takeaways from that are that I need to climb more - I'm trying to address that by going to Craggy at lunchtime and getting some mileage in on the self-belayer as well as bouldering. That has its own pitfalls, but doing an additional 150 moves per session can't be a bad thing, even if it is climbing on blobs and routes that I know too well. Also, I need to start doing weights again. Not sure how I'm going to fit that in yet!

Friday - Cuvier re-match

Scott was really feeling the effects of yesterday on his ankle, so was going for a rest day anyway. We went to the Carrefour up past Cuvier first, to get the obligatory Pommerol before getting the last bit of climbing in. It was a little damp still, and not sticky damp either. But the warmup went well, Marie Rose first time, other stuff flashed and I felt more comfortable, both from having had a rest day so the skin and muscles were better, plus more accustomed to the style of climbing.

I had intended to purely try to get on Charcuterie, via Dutch's sequence of go for the RH crimp from the undercuts, rather than getting into the other undercut. But Scott persuaded me to get on the arete that I'd briefly tried on Wednesday. RH slot, LF on good hold, rock up on LF nobble to get LH sloper / crimpy layaway depending on how you prefer to take it, RF by LF and LF onto smear, then RH into crimp, RF goes into starting slot and then LF kind of hooking / flagging on the side of the arete to throw LH for high chickenhead. RH comes onto pinch the arete above the chickenhead , get the feet high (RF into RH crimp?) and go for the top of the arete, whereupon you really shouldn't fall since it's a good hold and you'd probably miss the mat if you fell from there anyway.

Whereas previously, I couldn't even sort out my feet enough to get the RH into the crimp and do the crux throw for the top, this time I did it first go, despite the damp. Just pysche and concentrate, sufficient rest and skin. Fucking basic things.

There was a group under Charcuterie, so I had a play on L'Abbatoir instead. Not done it for probably eleven years. Couldn't remember the sequence, I was getting close using a high LH sloper and kneebar, but conditions / skin / strength / time weren't permitting it today. Only had three goes, got further each time, but had to sack it off.

Had quite a speedy journey back up; at one point Scott had to brake for a van that was going slowly in the fast lane and fortuitously went past a gendarme with a speed gun. I commented that was a bit lucky and maybe we ought to observe the speed limits. Alas, he got clocked doing 126 in an 80 zone at the turn-off for the ferry-port and we got a motorcycle escort to a cashpoint to pay the 90€ fine.

Got home without too much bother, quick Thai curry and then crashed.

Thursday - Apremont

Still no rain, so went to Apremont with the team again. Left my stuff in the car, to enforce the rest day and hopefully just help Scott climb well. He had a good warm up on a few yellows and then the others arrived and we moved over to a new area. Scott, Laura, Sarah and Fi were doing the blues and other stuff to warm up. Scott's ankle seemed to be holding up under all the strapping. Wandered under a problem that Laurie was trying. Cligne de l'oeil, or Wink as it's translated. Font 7a of loveliness; RH high layaway, step up to get good LH dish / crimp. RH crimpy layway, LF into starting (staring!) pocket and then RF heel-hooking on starting layaway. Go for top, match, shuffle right to the good bit and sort the feet out before pressing out the top. Scott got it fourth go or something, very good effort. That's his trip basically, Font 7a in Font. Fair play. Laurie left it for later.

Mooched off to join the others over at Delta Roc, up the route de la solitude. Didn't remember / realise that Apremont is so big. Delta Roc again is 7a, didn't quite look like my sort of thing (slabby arete) but again, quality problem. Scott wasn't quite trusting his ankle on that one, understandable. Again, hero effort from Laurie, getting it seventh go or something stupid, on his fifth day on. Dutch got it with a more obvious hooking method, as did Dave or Hoggie, can't remember which. Barson was close too.

Over finally to Science Friction and la Lune (6c), which was Fi's demon for the day. Couldn't quite get on the top hold enough to pull onto it. Looked good; Scott thought that the first move was too powerful the way she was doing it, but then he'd had a long day. La fleur de rhum (7a+) a bit further up looked flashable; Emma was making progress on it, and then a lovely wall to the right of it, on chickenhead weirdness above a nasty landing (6c/7a?). Coefield said it's not too bad though - he did it last Christmas and exited left rather than right due to snow on top! (Like a Baboon trying to open a Kinder egg!)

Again, Laurie went back to Cligne de l'oeil and got it with the new sequence. Respect.

Wednesday - Cuvier

No rain in sight, so on to Cuvier with the team. Started to warm up but felt very sore. Kept going anyway, just to make sure that I wouldn't let any sort of recovery happen today. Thrashed on Marie Rose, tried three times on some 7a arete opposite la Forge that Laurie was doing. Just not happening, so left the guys to it and Hop-a-long and I went into Font to meet Fi and Emma. Fi was doing some shopping for her new house; Emma was just being professional and avoiding the temptation to climb. Had the world's most expensive beer in one of the cafes and took off to prepare for the BBQ at the gite. Bloody palace!

Tuesday - Isatis

Late risers, to give the day a chance to dry out the rock. Then went to Isatis; my intention was to have a fairly long day of easy-ish problems on the reds and then take a rest day prior to blasting on Thursday. That tied up with the forecast that we had, that Wednesday was supposed to bucket it down.

We got to Isatis and it didn't seem too bad. The wind was up and drying things out nicely, so sent the guys a text telling them to get their arses in gear. Apparently that tipped them sufficiently to come out, since they were sat there arguing about where would dry out first.

Scott and I did most of the first eighteen reds (missed out a few wet ones), repeating a few that were enjoyable. I didn't feel that I was climbing that well, but felt fairly strong and was looking forward to getting some stuff done. Scottie seemed to be having fun as well and was pretty tuned in to the climbing. The guys arrived, Scott flashed the Crocodile thing (silly thing, see Bleau video / DVD) and we had a bit of lunch.

Then followed the guys over to the Hautes Plaines. Never been over there before, really cool place. Quieter than Isatis and some really nice problems to do. I was trying a problem in a pit up on the ridge; only around 6c but it wasn't happening. Couldn't understand it. We went up a bit higher to where BANKSIE! had found a (7a) roof to suit Emma, but again, I couldn't climb for shit, couldn't concentrate, just thrashed and wasted muscle and skin. Scott looked good on it, Laurie(sp?) was so impressive, getting it about tenth go, just really fighting and stubborn. Oh well, just leave it for another day.

Did I bollocks. Dutch and Kim were trying a really enticing wall lower down (pull on with RH crimp, flag and go up for small projection to balance with LH before extending for high LH crimp / slight gaston. Skin too sore to pull on, but tried a few times, just to make sure.

Then Scott sprained his ankle playing rounders, and I had to help him walk off.

Monday - travelling down

Christ, Scott had a shitty journey last night. But he got here finally and we had a few hours kip before heading out to miss the joys of the M25 on a Monday morning. Got to Dover early doors and snagged an earlier ferry. Ferry food sucks! I don't think there are any eggs in the scrambled eggs, and the beans were watery and tastlesss. Should have stuck to croissants, but I was trying to keep the healthy thing going.

Got to Milly in just under four hours - not bad. Sorted out the tents - John had forgotten to include pegs to the one I'd borrowed, so we improvised and sent slagging texts. Then headed off to Apremont, thinking that it was a bit showery, but it would be close to the road.

Arse. Road was closed, so couldn't drive all the way to the main car park. Instead, parked at the south end and bush-whacked around for a bit.

Finally got to the near car park area. Easy problems were all wet, so ended up doing stuff that was probably too hard, and wasted too much skin. Stupid, where's my self-control? That's what happens when you don't get out on rock much.

Didn't hear back from the others, so we just sorted out food at the campsite. It started to bucket down, so we cooked at the toilet block, hopefully not setting a precedent for the rest of the trip.

Pre-Font trip

So, I've been training reasonably well. I had a bit of a gastric infection a week ago and missed some training, but otherwise I think I'm going pretty well and hope to do some good stuff. Last time I was in Font (two years ago!) I was not quite doing Surprise (bad sequence) and was trying Alta as well, but had the sequence really bad for that. I was trying to go from the starting crimps to a high left good flat hold, but the normal way is to reach into the undercut first with the right and then move across using an intermediate. Hoping to do better with it this time - I've put 5 kg onto my deadhang whilst maintaining the same weight, so I'm stronger than last time. On blobs at Craggy, I'm doing OK, but it will be interesting to see how it transfers to rock.

Mirroring the parents

Al took Callum to a third birthday party for one of his friend's yesterday. One of his other friend's 'had to sit on the naughty step' for spitting at Callum, but Elliot came up to the Bash later and apologised. Callum's response?

'That's not good enough, Elliot'! Where did he learn that ...

Bloody Monkeys

Took the boys to Longleat Safari Park today. Callum was very excited, but Connor managed to fall asleep just before we got there!

So we went through the first bit, which had the giraffes, zebras, ostriches and some other stuff. Then we went round the flamingoes up to the monkey enclosure. Al voted to take the shiny new Zafira in whereas I was a bit more cautious, but Callum was pretty vocal about what he wanted to see. So in we went.

It was obviously very funny to watch the monkeys dismantle other peoples cars. They must go through some sort of training programme. Rights lads, next up, Audi A3. Weaknesses, trim comes away easily, remember the arial if they haven't retracted it and the rear wiper will come off if you hang on it hard enough. And so it was that some of the little nasties got on our roof, and went straight for the rear-screen wash projector. Off in a flash. I even saw one using a branch as a crowbar to get a wiper off another car.

Callum and Al thought I accelerated rather hard to coax one of the little fellas off the car, but it was more like controlled kangaroo hops to encourage the monkey to leave. Connor woke up in the next enclosure and saw the gazel-thingies and deer, then caught the tiger and lions as well, so he was bouncing off the walls. Little smashers!

Separation Anxiety

Al's away at the moment and phoned tonight while Callum was still in the bath.

Callum : 'Was that Mummy?'
Me: 'Yes, and she says she loves you very much'
Callum : 'Yeah, but I've got a bouncing frog!'

Maybe you had to be there.

Post-Project review - North Wales trip

1. If you arrive in the Pass and it's dry, go climbing. The BBQ can wait, but tomorrow will probably bring rain.


2. A bunch of Sarf London market boys will not be able to thrash up Snowdon in proper Northern rain that hurts, Wayne and his brother excepting.


3. Never go hill-walking with a fell-runner. Doing the Llanberis track up and down in a little over three hours is going to hurt later this week.


4. The Vaynol is very good for supping - good choice with the campsite, Mr Velupillai.


5. The campsite was basic and I'm probably needing my creature comforts more in my old age.


6. The Vaynol sucked for food. They got my order wrong, brought the food out cold and is was generally unimpressive. I made up for it by drinking lots of Robinson's. (c.f. point 4)


7. Not doing any climbing for a while over the hot summer months leaves Fairy Liquid soft hands and flabby muscle which doesn't cope well with the Cromlech boulders.


8. Whereever you go climbing in the world, you will bump into people you know from Sheffield. Mr Busby looked far too fit and strong for my liking, so I'm going to have to start getting thin so that I can be good enough to hold his rope next time I see him at Rubicon!

Australian influences

So my brother and his family visited, and I didn't write anything at the time. The one thing that sticks in the mind is his son, and my allusion to Beaker.
