The Next HOPE recap

The Next HOPE, Hackers on Planet Earth, held in New York, at the Hotel Pennsylvania Jul 16-18th. HOPE is a bi-annual conference, which concentrates on technology and other subjects (..everything?) that interests the hacker mind. This year's event was my first, and my first time in the United States. I'll try to sum up, in fairly chronological order what happened during the last week.

I flew to New York via Amsterdam, on KLM / Delta. Security was a main concern from the get-go. To start off, you had to fill out a form on the web, where you basically state that you are a good person, and not up to bad things. Or that you were involved in Nazi activity during the second World War. Normal questions such as that. Completing the form gives you a 12 month permit to travel to the USA; this does not however stop them from turning you back if they don't like you for any reason. ESTA is something that Visa Waiver countries have to fill out these days. No I-94 forms though, which makes traveling a bit easier, i suppose, since you don't have to physically fill in forms, and keep part of it for flying back...

The ride to Amsterdam was largely uneventful, but in Amsterdam, security was ramped up. First you had to pass regular Airport Security, to get into Terminal .. C? to fly to the US in the first place. When I got to the gate, there was a secondary security checkpoint, set up just for that gate. Each traveling party is asked individually to come talk to an official about who you are, who packed your bags and where you are going. Kind of a personal interview. After that, you're taken through a standard security checkpoint, though everyone was frisked and patted through, no matter what the metal detector said. Some people had their carry-on bags opened and checked separately.

The interesting part about this security checkpoint was the fact that they had two of the full-body scanners present. They were not used however, which was curious. Two phone-booth sized things in the middle of the floor, which could be closed around a passenger, and supposedly, used to "nude-scan" a person. It would have been nice to see that in action.

So, get on the plane in Amsterdam (767-300ER), and during the 8 hour flight, you fill in the US Customs form, which declares what you are bringing (and leaving) in the US, whether you are carrying samples of biological material, whether you've had contact with farm animals (yeah, right), and such questions. The form was collected by customs agents at the airport when you arrive.

We flew into Newark. Upon landing, we were taken through a security checkpoint, and then sent to queue for the actual Border Control checkpoints. Here, we are once again asked the same questions (Who are you, why are you here..), and then given the final go-ahead to step on US soil. They had ominous looking "Screening rooms" for people who looked suspicious, or who just wanted to have their assholes probed, i guess. Didn't see anyone get taken in there, but i did see Border Patrol agents, or whoever, DHS-people looking at travelers, supposedly for signs of nervousness etc.

Take the Airtrain (a monorail system) to a train station, and then the NJ Transit train into Penn Station. 15 dollars for the entire trip, which wasn't bad at all. Trains were fairly clean and air-conditioned, which was nice, because the heat was nigh unbearable.

At Penn Station, we had at least three different agencies at work, all with different uniforms, weaponry and bad-assery. The Department of Homeland Security had these bad-ass looking guys in tan BDU's, thigh-holsters for their pistols and sunglasses inside. The National Guard had standard beige camo, and assault rifles. NYPD had their guys in blue and whatnot, and i think the Transportation Security Administration had some officers as well, though not armed. There were "soldiers" everywhere. I felt like, if i was running for some reason, i would just have been shot.. No incidents to report though.

There were signs everywhere at Penn Station, in the style of "See something suspicious? Report it", with pictures of "abandoned bags" and other such horror. Just felt like they were creating an atmosphere of fear, instead of an atmosphere of security.

Hotel Pennsylvania was at the corner of 33rd street and 7th avenue, opposite Penn Station / Madison Square Garden. A central location in midtown Manhattan, with easy access to all areas of New York, either walking, by buss or by subway. Everything seemed to flow through midtown. The Empire State Building was a few blocks away, and so was Time Square.

The Hotel had an offer for conference visitors, which made the place even cheaper, and for midtown Manhattan, 129 dollars per night *is* cheap. The rooms were pretty basic, some would even say run down. Paint had chipped on many walls. There was a disgusting black splotch of mold on the roof (probably below the A/C device in the room above), and a missing lock (i mean there was no lock, no mechanism, and the handle was lose) in the bathroom door. The good things were: Clean and comfortable bed, hot shower, working A/C and a working TV. I was pleased, and after i got off the initial shock, i had a pleasant stay. Hotel personel was nice and polite, and the services of the hotel in general were good.

The Conference

The conference started in earnest on Friday. I however, decided to take the elevator up to the 18th floor, where the main speaking areas were, and sign up for some volunteer work. I walked up to the desk, "manned" by Lindsay (Nick Farr's right arm during the conference), and signed up to do some AV work. I took the elevator down to the Mezzanine level, where the Vendor and workshop areas were going to be, and started helping out by unloading trucks and carrying stuff. Later that evening, we put down some (read: a lot!) of cable for speakers, video, light and whatnot. By the end of Thursday, things were looking awesome and we were ready to start the conference the following morning! We had lots of people "from different walks of life" helping out with all kinds of stuff. As for the AV and lighting stuff, guys from Carnegie Mellon university (college?) were present to co-ordinate stuff, and they had lent/rented most of the equipment from different places. I met loads of interesting people during the volunteer work, including Lindsay, Nick Farr, Rudy, Daydreamer, Slowpoke, Kelly, and loooads of other people whom i can't even start naming here, due to the sheer volume.

Volunteering was a great job, as you got to see the inner workings of the conference, meet people, and see the hotel "backstage". As a hacker, seeing how something works is always interesting. Helping out and learning new things in the process is even better! I learned a whole bunch about AV-tech, and ended up doing a bunch of the video work. In all, i clocked in nearly 30 hours of volunteer work, most of that spent either building or tearing down the conference, and the rest video-taping the different talks. They will all be online later at the HOPE website, at http://www.hope.net.

In all, there were close to 100 talks, running on four different tracks, in four different rooms, all named after significant inventors and innovators in the technical field: Bell, Tesla, Lovelace and Morse. There was no way to see them all, as they ran in parallel, but that's why there will be audio and video (some of it filmed by me! so when it sucks, you know who to blame :) ).

The Mezzanine level had the vendor and workshop areas, as well as the "administrative" areas, such as the Information desk, the Security desk, and the noc NOC. You could try out Segways, solder some stuff in the hackerspace area, grab a Club Mate or just chill out on the hammocks. Later in the evening, there were some "chiptune" concerts and movies being shown. You could learn how to lockpick, buy some books, pick up cool stickers or just talk to people. Just sitting down on Saturday evening with some people, i had an 8 hour discussion about all kinds of issues ranging from the Metrocard system in Finland, to politics to mandatory military service. These were people i didn't know from before! Spontaneous contact with nice people was... nice. Just sit down, and start talking.

Oh boy... there is so much to say..  I'll probably split this post into two or more pieces. Too much to say. Still jet-lagged, and tired from the whole ordeal.

Lab .. and life-updates

So as many of you have heard, my wife of 6 wonderful (no sarcasm here.) years has left me. She moved out yesterday, and left me here in this god damn 4 room apartment alone. This means, it's time to look for a new place to live (still in progress), and do some redecorating. The lab will undergo extensive rework, and i'll try to pull a "Didak" and document the process here. My old corner-desk is going to B, and i've already bought a 160cm x 80 cm desk for my lab. I'm also replacing my 2x22" screens with one FullHD 24" screen (one to start off, more later), and possibly an Ergotron LX arm for the screen. Those are really hard (or slow) to come by here in Finland, so we'll have to see about that.

So what i've bought so far is the Galant desk (man i feel like watching Fight Club again...), with T-shaped legs from IKEA - 169€, and a BenQ G2420HDBL screen from Jimm's PC-Store - 188€.

Pics will come later today as i get some help to move stuff around. I hope i can get cables done in a smooth operating fashion. No more tangles on the floor, thanks.

Sheep

Today's blogpost is inspired by the problem with our dear Finnish people. Or maybe it's a global thing, humanity itself.

I'm talking about a) tolerance b) being a fucking sheep. Let me present to you a problem that i've been having lately.

VR is the state operated railway here in Finland. It operates all trains, and is responsible for collecting ticket fees, operating the stations, platforms etc. They have steadily been increasing prices of train tickets, due to uh.. inflation and rises in operating costs. However, trains don't seem to go on time during the winter, which makes me a bit angry. My problem is, that i'm constantly paying my ticket, and yet, the trains i count on to get to work and back are never on time when there is a little snow on the ground.

Granted, this winter has been exceptionally bad, with more snow than in any previous year since the 1960's, but none the less. Where is my money going? It sure as hell isn't going to improving the reliability of trains in "extreme" weather

Winter is not a new concept in Finland, and many places operate trains far more north than Helsinki, in southern Finland. We get snow, which starts gathering in the machinery of the train, the wheels, the gears and whatnot, which is preventing trains from moving. At least this is according to VR. Also we are having problems with tracks freezing so badly, trains can't switch tracks as they have to to reach the correct places.

This to me seems like an engineering problem. If you throw enough money at a problem it usually goes away. Increase the amount of plows on the tracks. Put heaters in places where icing is a problem. But this isn't happening. Why?

Traditionally, when consumers (that's you and me) have a problem with something, they start complaining. This is happening now with the trains. Inneccent complaining results in either a) the company shutting down because they can't or can't afford to fix the issues that the complaints are about, b) the company fixing the problem c) company lowering prices or offering compensation due to lost revenue/time or whatever or the consumers. This isn't happening either.

VR could shut down their customer support, and stop notifying people of late trains, and what would we do? We'd keep complaining, and keep traveling, because that's what we do. That's all we do. We have no other option but to keep traveling. They could just lay off 90% of all their staff, send them to Bermuda or where ever, and there isn't a damn thing we can do about it. We either accept the problems, or we stop using trains. Which isn't happening. So we make like sheep.

Why i keep paying for tickets during winter, i don't know. There should be no ticket fees at all. But they just keep raising the prices, and we keep paying. If a ticket inspector came on any of these late trains (i waited 45 minutes this morning), i would probably punch him the fuck out. But there's a problem with those guys too. Inspectors get paid from the inspection fees (80 euro, or.. what, 120 dollars?) from everyone traveling without a valid ticket. When they increase the inspection cost, it doesn't go toward anything else, except paying for more inspectors.

It's like traffic cameras in Helsinki. The fines sent out by traffic camera pictures, are used to invest in new cameras, so more fines can be had, so more cameras can be bought...

So how is this organisation still operating? Because we are sheep and we don't really care. We just accept what the news is telling us, what VR is telling us and accep that there is nothing anyone can do. This is 2010. We are a nothern country. We have had winter here since the planet was created, oh, 4.6 billion years ago. This is not a new thing. This is an engineering problem that isn't being dealt with, because frankly, they don't need to.

Recent Developments

So it's been a long while since i last wrote anything. So what's been happening lately. Well, a few things.

Dorsia has been replaced by a "slightly" less powerful machine, namely an old P3 rig. Dorsia is my shell machine that i've used to hand out shells to people i know. Nothing really special here, it does the same job as before, but with less overhead. The previous Dorsia machine was a G4p HP Proliant, with dual Xeon's, so it's best off doing something else. In this case, something else is installing VMware ESXi on it, and using it as a test bench for numerous virtual machines. It's better suited for that task. This project is stil pending, but, the server hardware is compatible with ESXi, and i should get on that with P at some point. Our plan is to build a kind of virtual lab environment, where we can have different server operating systems, such as Windows 2003 and 2008, among others, and then run a hostile machine,perhaps with the recently released Backtrack 4 final. As soon as we have time..

I've ordered a netbook. So yeah, i became yet another sheep and got myself a netbook. Yes, i'm aware they are very slow etc. etc, but i'm just interested in surfing the web and writing stuff down, and for that, i think it'll be just fine. The one i got was a Samsung N140, which is a 10" netbook, with a 1.6GHz Atom 270 processor, 2 gigs of memory, a 320 gig hard drive (5400rpm), and various other parts of lesser interest. There are a few things that are of concern. 1) Is the machine powerful enough to run some flash content? I'm not talking about some multimedia extravaganza, but simply youtube and such? 2) The resolution is small, and i know this. But, it has a VGA out, and where i'll be using it "proper", i'll have an external screen to hook up to it.

Basically, i'm not expecting much, but it'll be interesting to see how it compares with my previous "netbook", my Thinkpad X41, which has developed some problems with the battery and charging. This puppy has a 1.6 GHz Centrino,  with 2 gigs of memory. I'll be running some benchmarks to see how the Atom fares against this 5 year old machine. Should be interesting, as there aren't a lot of benchmarks that compare older hardware with netbooks, and as M pointed out, there are so many different architechtures; comparison becomes difficult on a larger scale. I'll be reporting on this as soon as i get the machine, which should be next week.

I'm also trying to find out what the perfect linux distro would be to install on this. I'm taking suggestions, if you have them.

Adobe presented me with an interesting perdicamen this week at work. I was fiddling around with trying to get the Adobe PDF printer working under Windows 7. This proved to be a bitch. After countless hours of testing, i found out that Adobe Acrobat version 7, works just fine under windows 7. This is an old old version, from like 2003, which doesn't even have support for Vista, let alone Windows 7. Adobe 8, which was used in this particular case, just didn't work, not even with the latest patches. It installed the printer, but you were unable to use it, as Acrobat claimed the product was unactivated (it worked otherwise just fine, so i think that's just a bogus error message). Again, version 9, the latest version (patch 9.3 released 14th of January) has official Windows 7 support as of 9.2, and that worked fine from the get go.

So Adobe, why doesn't version 8 work, when the older technology of version 7 works just fine? You wouldn't be out to get Windows 7 users to buy Acrobat 9 now would you? Tsk tsk.

Glamorama, the recent book by author Bret Easton Ellis (notably of American Psycho-fame), is what i'm reading next. Hopefully, even today. It was shipped out from Jersey, at play.com last week, so i should be getting it either today or tomorrow.I hope it's as good as American Psycho! I think i'll be reading his entire bibliography, since i very much like his topics (glamour,  yuppies, decadence and horror), and his writing style.

Ham radio. Me and B decided we were going to become ham radio operators during the year of 2010. We haven't started yet, but i'm definately going through with this. I have a few ham friends who i'll be talking to about where to take the exam and so on. The basic level exam isn't too hard, plus i was in the signals battalion during my one-year army stint, so this shouldn't really be a problem by any stretch of the imagination.

Assembly 2009 – Day 4 – 01:20

Last day here at the Hartwall Arena in  Helsinki. Just finished Left 4 Dead on Normal (yeah, big whoop). Before that, we saw the rest of the compos, such as Demo and 64k , and the second price ceremony.

The ceremony had some traditional hijinks by the Netcrew, as they were dressed in Star Wars costumes (with awesome lightsabers), threatening the other organizers. Awesome display, but i have to say, even as a megageek, the geek-o-meter was hitting a high fucking note on that one.

So, L4D done, new graphics card working like a charm. Uh. Time for a late night snack, and more cafeine so i can last until the morning. We're leaving before noon, since there's not too much to see anymore. Last price ceremony and ending ceremony, but i'm not too big on those. Compos are cool, but.. other than that, i don't need it.

Assembly 2009 – Day 3 – 15:12

Music compo underway. Some nice electric tunes, such as Pump My Porn, by renoise.

Just went out to Jimm's Pc-Store to get a new graphics card, an ASUS Ati Radeon 4850, 512MB DDR. It should serve me well, considering the fact that i have a crossfire motherboard, meaning that i can just get another one later. This isn't as good as the GTX 260 that i was going to get, but on the other hand, this is 50 bucks (at least) cheaper, and is better supported by my motherboard. I'm not too sad about my choice.

I was looking in to GPU cracking of WPA keys, and found that using a tool called Pyrit, which utilizes ATI Stream, and NVIDIA CUDA technology, you can do about 7800 PMK's per second where as on the 260 you can do about 9000. In 3DMark 2006 there's about a 1000 point difference between the two, which is reasonable.

I could have gotten a similarly priced 250 Nvidia, but that's basically a hopped up 8800 or something. Which i have now. This card is going to my dad.

I'll install the card once this compo is done.

Assembly 2009 – Day 3 – 01:04

Oh hi.

Oldschool demo compo only had two fucking entries. A little sad, but it was saved by Unreal Voodoo's awesome piece "3½ inches is enough", which had a solid plot, and an awesome oldschool theme, where the old tech prevails :)

No more compos for this night, next up is music compo 14:30. Now it's time to do some gaming, and maybe something else.

Oh, installed the Boinc client on Agamemnon, the dual Xeon server.

Assembly 2009 – Day 3 – 00:26

Just saw the 4K intro, and again.. amazing productions. A few very nice ones, including tAAt's production with the fucking elephants :D "Irrelephants", brilliant name, brilliant idea.

Other good ones included "Patenga" by Traction, and the sony-logo-mockup "dollop" by Sqny. Awesome pieces. Some lazy entries, but overall, very high quality visuals this year!

Next up: Old School Demo
