Jailbreak!
Okay, I finally did it. I hacked my iPhone. Which makes it sound like I did something clever, but really it was nothing at all. There's a new web site, jailbreakme.com, that exploits a bug in the TIFF handling code to install the jailbreak hack. It takes two minutes, and there appears to be almost no risk of damage to the phone or voiding my warranty. All I did was visit a web site with Apple's buggy browser - if Apple have a problem with that, they are really going to get into a whole lot of trouble.

Two things convinced me to do it, though. The second thing was the fact that the jailbreak hack exploits and then fixes a security hole in the phone. With all the virus writers and bitter students around I figured that it wouldn't be long before a malicious hacker found a way to screw with my new toy, and that's the last thing I want. I won't touch Internet Explorer or LookOut since they are just hack magnets, and now it seems that Safari is no better. Bring on Firefox for the iPhone. Maybe now it's hacked I can install it?

If you want to hack your iPhone, just visit jailbreakme.com, scroll to the bottom and select "Install AppSnapp". After a few seconds Safari will quit and return you to the home screen. Maybe a minute later you'll see the "busy" disc in the centre of the screen, then it'll go back to the Unlock screen. Slide the slider and you're in. You'll see that iTunes is now on the left and there's a new icon.

Two tips: 1) Don't try to do this over EDGE. Make sure you're connected to a WiFi network. 2) If it doesn't work, reboot your phone and try again. Hold down the "home" button on the front and the "lock" button at the top until the phone reboots and you see the Apple logo.

In the pants
While investigating a strange error message in part of our project I came across an entry on a German forum. Not being much of a German speaker (although I do own several Rammstein albums) I naturally turned to Google for assistance. I was particularly struck by this comment:

Du versucht eine Instanz der Klasse "java.util.logging.Logger" per RMI zu verschicken, was natürlich in die Hose geht. (sun wird doch nicht seine eigenen Systeme unterstützen, nein, das wäre ja zu einfach).

You tried an instance of the class "java.util.logging.Logger" by RMI to ship, which of course in the pants. (Sun, but not his own support systems, no, that would be too easy).

You tried to transmit an instance of the class "java.util.logging.Logger" via RMI, which is of course a complete flop. Sun would certainly not support your approach-- that would be too easy.

Update 1: According to Jan, In die Hose gehen corresponds with crapping out, quite literally. Basically crap into ones pants. It is used to describe a failure in a derogative way. Something that failed, but shouldn't have, due to bad design or idiocy or ignorance. Now, this is not the definition in the dictionary, so don't think: wow, the Germans DO have a word for everything!

Update 2: If anyone is interested, the root cause of the problem was trying to serialise a class that had declared an instance of the Logger. The fix was to declare the instance transient

Alec Muffett and the TeraPods
Alec has published his CEC presentation. And while I never actually made it to any of this year's breakouts, I doubt that many were as insightful, thought provoking and downright amusing as this one was. It's also very well put together; must have taken quite a bit of effort. I was impressed that even though I'm watching it on my Solaris box, throughout the entire 40 minutes the audio and video stayed in sync; whether that's down to the latest Flash V9 plug-in, the blip.tv hosting service or something else, I don't know.

As an aside, the way it was presented reminded me of the classic Bob Dylan video for Subterranean Homesick Blues (and Weird Al Yankovic's superb parody of it). As Alec pointed out, the deck of cue-cards required would have been enormous, but I may just have had an idea for next year's Video Challenge...

Oh, and Alec Muffett and the TeraPods would be a great name for a rock band.

Home from Vegas
Finally home from Vegas after a busy week. US Airways Flight 160 was delayed by almost an hour so i caught up on email and listened to some podcasts. If you didn't check out the CEC Podcasts you should.

Had dinner at Cafe Ba-Ba-Reeba last night with a bunch of Europeans, including Dave Levy, Mike Ramchand, Eric Bezille, Mathias Pfützner and Chris Gerhard. Chris had some interesting comments on CEC so I thought I'd address a few of them.

Use Sun Ray 2s with the vpn firmware installed so that they can be punched into Sun.
Couldn't agree more. I hadn't heard about this until a few days ago; when I did I contacted the group that were supplying the hardware. This group supplies all of Sun's trade shows and has a huge warehouse full of kit in Milpitas. It turned out that CEC clashed with a storage conference in Denver, and their limited number of SunRay 2s were already committed to that event. Also we had requested 150 SunRays and I don't believe they have 150 SunRay 2s. Hopefully next year there won't be a clash and by then maybe they'll have more SunRay 2s anyway.

I have to say, setting up the SunRays was really easy this year. The SunRay team have done a great job making utadm so much simpler and reliable than before. It did fail on two of the servers - the SunRays got the firmware update but then did not restart properly, but utadm -d followed by utadm -a cleaned it up nicely.

Put the Sun Rays into a FOG so that if a Sun Ray server goes down the individual Sun Rays are still usable.
This sounds like a good idea. I wish I'd had more time to work with the SunRays beforehand; unfortunately I didn't get out of hospital until a couple of days before the servers had to be shipped, so everything was kind of rushed. Hopefully next year I'll have more time and can talk to some SunRay experts to find out the best way to configure them.

Have some Sun Rays in Paris near the main conference room.
It's an interesting idea, and while I agree in principle I'm not sure how it would work. At conventions like JavaOne they line the corridors with them, but that's not really practical in a hotel, and certainly not one like Paris/Bally's. They have to be in a room that can be properly secured; as I mentioned in an earlier post several bits of equipment did go missing despite our best efforts at security. So while I agree with you, I wouldn't hold your breath.

It would be good if the content builder did not give times for the presentations. Simply allows users to choose the top 20 presentations that they wish to attend numbering them 1 to 20. Then get the computer to work out the room allocations such that we get the best allocation of slots.
Interesting idea. You're never going to please everyone (believe it or not I actually worked on a program like this on a Commodore PET over 25 years ago. It was to handle school class timetabling issues and won me the School Prize for Applied Computing - a 5 quid book token that I spent on a copy of The Vic Revealed).

I have to say, I always find the Schedule Builder program a pain in the arse to use. It wasn't quite so bad this year because no sessions were repeated, but still.

More deep technical presentations for those of us who are that way inclined.
You need to take that up with the selection committee. However the big problem is that you're always limited to the set of papers that are proposed.

Have the party somewhere that can easily cope with the numbers rather than somewhere that can't.
Amen.

The other thing that we really need to think about next year is the issue of power in the breakout rooms and general session rooms.

If you have any other thoughts feel free to leave a comment and I'll try to get them to the right people.

Bitching about my iPhone again.
The iPhone includes a 2 megapixel camera. It doesn't take bad pictures (for a phone) even though its low-light handling is poor and it has no zoom or flash. It'll never replace my Canon Powershot, but it's great that I have been able to carry around one device and email the photos directly to Flickr.

Unfortunately, there are some huge issues with it, both concerning moving the photos to a computer. When you view them on the phone the pictures are in chronological order. But when I use the Microsoft Camera Wizard to transfer them to my laptop they get completely shuffled naming wise and it doesn't maintain the orientation correctly. The other problem is that it keeps locking up; the laptop says that it can't transfer the file and I have to reboot the phone.

The other thing that really bugs me is that there's no scrollbar on the web browser or email client. There is no quick way to skip to the end of a 250Kb message, which is insanely frustrating.

The inability to select a block of text to cut and paste is frustrating too.

Closing Session
Dan Berg keeps banging on about Second Life. Apparently it's been very popular. Granted it's very pretty, but I still don't get it.

Chat show featuring representatives from EBay, EDS, Microsoft and Fox pontificating on "the end of computing as we know it". But it doesn't seem to be capturing the attendees' interest - the room is half empty and a lot of people are walking out.

Don Grantham. I didn't realise he was British. Lots of rah-rah: The stock is up, we are delivering on our commitments, we are growing and making profits at last. We're on track to make 10% margin in FY09 as promised. The room is getting emptier; this should have been yesterday's session with Jonathan closing it out.

He also spoke about Sun Connection and how important it is - that's two major plugs in general sessions. He even mentioned SRS :(

Here we go, he's about to say what the plan is for next year - he's signed the contract to hold it in Las Vegas again next November. He wasn't specific as to exactly where - will it be here at Paris/Bally's again? Probably; I'll try to find out. I admit I'm ambivalent about that - on the one hand Vegas is a good location, I've had a great time, and I love that it takes just moments to walk from my room to the various sessions, but on the down side security has been a nightmare simply because (as I think I blogged earlier) it's not just a hotel, it's a massive hotel that's open 24x7 and actively encourages people to wander in. We've had equipment go missing and all kinds of technical issues specifically caused by not being in a true convention centre.

Update:Dan confirmed - same place.

I have no idea who put together the closing video, but I'm sure he's on crystal meth. I've never seen so many speeded-up clips and ultra-fast zooms and pans - I thought I was watching a Blipvert. I'm surprised that nobody had a seizure or exploded.

Party at the Palms
Well, that was disappointing. It took 45 minutes to get there, only to find that the place was insanely cramped and the lines for the drinks and food were endless. The cover band were so loud that conversation was impossible - SMS was the best option for communication. Once I squeezed into Rain things got a little better; a few video games set to free play, shorter lines for the bar (the red wine was undrinkable) and food (very bad Taquitos and chips) and slightly better entertainment; some guy playing with a flaming sword, but that was about it. I bailed very early and went to dinner with friends. I hope that things improved after I left, but somehow I doubt it.

Joined up thinking
As we all know, the message went out: Bring your laptops to CEC, there will be wireless. Sure, there's wireless; there are at least three access points in the General Session area, and Sun is paying a ridiculous amount for it. But where's the power? My laptop battery won't last an hour without dying.

Yeah, nobody thought about that. There are just four (I counted them) wall outlets in the ballroom - you need to get there early. So I thought it might be a good idea to run power to a few rows of seats - we have some 30' contractor grade power cords from last year. All we need to do is decide where to put them, right?

Wrong. If the organisers want to do anything official then the electrical contractors have to do it; they have to supply the cables, tape them down and charge us for the power. Given that there's only one general session left it simply isn't worth it. I must remember to raise this issue next year before the damn thing starts. Of course if attendees are using the wall outlets, that's a seperate matter entirely.

On a completely unrelated note, I happen to have four power strips in my laptop bag. Just in case I need them for anything.

UPDATE: Turns out I was being too harsh. It was just a matter of getting to talk to the right person. There WILL BE POWER in the last General Session after all - the hotel is running 100 amps with power strips along the far wall, to the right as you face the stage. Huge props to Atilla from conference organisers GPJ and Brian from the Hotel staff for arranging this.

Blogging at CEC

Me and Thomas Wagner blogging at the Product Launch. No, I'm not asleep - I'm at the back of the hall trying to see John Fowler.

Product Launch
Another first for CEC - a worldwide product launch. John Fowler announcing three T2 based systems: the T6320 Blade module and the T5120 and T5220 rack mount systems. They look pretty sweet. 8 cores (64 threads) and 64Gb memory, 10 Gig ethernet, hardware crypto, world record performance.

Filling a 48 blade rack with T6320s gives you over 3,000 threads! Yow!

The only real differences between the T5120 and T5220 are the height; the T5220 supports more disks and PCI cards, so consequently has higher rated PSUs, and has bigger (and thus more reliable) fans.

General Session 2
Dave Douglas talking about Eco Responsibility. This is the first time I've heard him speak. It's very encouraging; Sun is improving energy efficiency both in our products and our data centres. Apparently our new Santa Clara data centre is very impressive; PG&E gave us a huge rebate for energy efficiency. I must get a tour when I get home.

We are getting to the point that computers cost more to run than they do to acquire. Interesting Q&A session; wish it could have been longer, but now it's time for the main event.

Jonathan Schwartz He gave a plug for the Sun Connection web site. Brief shot of the webcast in Second Life; looks like there are a few people there. Everyone looks very fit; guess that's the attraction - in Second Life you aren't old fat and ugly. You can even have huge black wings, apparently. Dan says there are 1,000 people in there but I can only see about thirty.

Nice rant against the NetApp lawsuit. It will be interesting to see how that pans out since Sun has such a massive patent portfolio.

Crisis? Which crisis?
Now I remember why it's a bad idea to hold CEC in a hotel. For the last few years we've held it at proper convention centres - either in Denver or San Francisco. The key benefit is that at the end of the day you lock down the entire building - everyone leaves except for a few security guards and the chances of random bits of hardware suddenly evolving into more mobile life forms are greatly diminished. In a hotel, it's much trickier - especially in a hotel that actively encourages people to stay up all night and to come in from outside. As a result, all the systems have to get locked away at the end of the day and replaced first thing in the morning.

That in itself is a headache, but then you have to factor in the static (we are in a desert) which has fried at least three of our Ultra 20s so far and the issues that we had with the NVidia cards vs the projectors. It's been a huge headache

Yesterday the network in the pavillion was up and down like a kid on a trampoline. Today it was the turn of the wireless. Apparently they aren't used to having 3,000+ geeks, all with WiFi enabled devices, descending on the place.

Then there are the issues with people needing SWAN access. It was supposed to have been explained to people that if they needed to register for punchin before they came here, but I guess the message didn't get out. Then the Broomfield punchin point stopped responding at a critical time. Oh what fun.

As if that wasn't enough, one of the SunRay servers died on me. The damn thing wouldn't even reboot. So now I've replaced it we no longer have a backup. I hope none of the others fail. In the meantime, it seems that trying to use rsync to keep the servers synchronised was not such a good idea after all. It worked OK in testing, but in production each sync takes ages. So I'm switching back to the idea of using one of the servers as an NFS server which I should have done in the first place.

Yeah, Vegas is a fun place, but there's definitely something to be said for the Moscone centre. The hot rumour is that next year they may try to hold it in Europe. I hope it's somewhere with a good convention centre. Anywhere but Birmingham NEC would be fine by me.
