This course about the Riverbed Steelhead appliance has given me some very interesting details of the design of the Steelhead appliance and the capabilities. The speed improvements on network traffic, either due to initial compression, or later when it detects patterns it has sent out earlier or because it optimises protocols like CIFS, NFS or HTTP(S), their are very impressive. As they say, it makes your data on the servers on the data-center feel like it is sitting under your desk. Plus the integration in your network makes it close to zero-administration, all you need to start is two Steelhead appliances, two ethernet cables, two IP addresses and their default gateways and it's up and running. Talk to me if you want a demo :-)
What happened the rest of this week? The USA got a new president, I met up with David Thiel for dinner on Sunday, I met up with Anton Holleman for dinner on Wednesday and Saturday, I met a lot of collaegues at the San Francisco Riverbed offices, I walked in San Francisco through Chinatown, the Financial District, to the Tram museum, around the piers at the east coast because I couldn't walk over the Bay Bridge (Whoever decided to make a bridge without a pedestrian lane?).
Television is here euhm... less than interesting. Except for PBS there aren't much channels I did recognize or would recommend. Discovery Channel has "in-taxi" gameshows, there are seventy channels with people competing for something and then giving or getting feedback on how they were doing and half of the TV series are an insult to my brains. The presenters of the Weather channel seem to be the most enthousiastic ones in their profession. At least in Australia there is 40% of the channels worth watching, it's about 2.5% here. Not to mention the quality of the surfaces with the "same" colour on NTSC... (enough for now, it just makes me open the window and shout "I am sick of this and want everybody to know")
The best pub I've been in was Eddie Rickerbacker's on 133 2nd street. It has old motorbikes hanging on the ceilings, miniature trains in the vitrines and a miniature railroad around the wall. And a fat cat walking around... A very nice place to be.
So what is left for the rest of the week? Tomorrow I will go to Sunnyvale, first with the BART train service and then with the CalTrain service (Yes, I love trains!). Over the week I will have my share of cases at the Riverbed TAC in Sunnyvale.

If you are on holiday in San Francisco, crossing the Golden Gate bridge is a must. You can drive over it with a car (well, you didn't need to come to SF for that, you can drive with a car whereever you want to) or walk over it (always exciting, but what are you going to do on the other side of that bridge?). Third option: You can cycle over it! Being a dutchman, I of course chose for that option.
Hiring bicycles in San Francisco is very easy when you're in the tourist area (i.e. near Fishermans Warf). From US$ 7 per hour for a simple bike to US$ 15 per hour for one with 3 / 8 gears plus air-suspension. Throw in two more dollars and they will pick you up when you have a flat tire. As long as you are back before the shop closes you can have it!
So, now for the trip: It is a trip between Fishermans Warf (North San Francisco) to Sausalito: Past the beaches, over the bridge, through the National Park (optional) and then to Sausalito for lunch and some drinks. And then everything back, but the National Park is optional again. See the Google Map for details, it is nearly complete except the places you go up and off the Redwood Highway: You have to go under it to get to the bicycle path on the other side. Just keep following the beaches and the signs for bicycles and the bridge.
What are the highlights?
Total length: About 30 kilometers because you have to cycle back.

The first part of my trip to San Francisco went easy and successfull: Customs in Australian didn't search my bag, the plane left on time (I watched (Video On Demand with Qantas is great) the movie "Where is Osama Bin Laden" by the same guy who did "Supersize Me" I think and the Australian movie "Cosi", both movies worth mentioning) and except for some nasty bumps over a couple of minutes it was all smooth, customs in the USA didn't ask too many questions (I guess I am just a statistic for them), my luggage was there on the caroussel when I was ready and the hotel was not too far away from the Montgomery station and the weather was nice (read on for more on that one...). With regarding to forgotten luggage: razor blades and socks: I only brought one pair of socks!
To go from the airport to the hotel I decided to go by train with BART, or Bay Area Rapid Transit for long. For U$ 5.35 (otherwise US$ 30.- for a taxi) you can't complain too much. The trains are clean and not too slow, but they make an awful noise when going around bends, so much that it started to hurt my ears. Note for people who need to keep receipts to bill back to work: Make sure you put 5 dollar-cents more on your ticket so you get it back when going through the final gates. I am not yet sure how to go from here to Sunnyvale, since the BART railroad doesn't go so far south.
The Courtyard Marriott hotel has free internet, but it requires a daily recharge, which comes by going to the frontpage and clicking on "1 Day Free Internet". The good news is that there is wireless network support too and that is used for the Riverbed provided laptop. If you are overseas and the people you try to call don't have Skype or internet access available, use the Skype dialout service! For three cents per minute I could talk to my wife and children yesterday (I know, this sounds like a bad ad)
The weather... It was wet, very wet. So I didn't do much walking outside yesterday due to ENOUMBRELLA. But I did walk through it to get some tea bags (the hotel does have free coffee but no free tea and the waterboiler, due to its use in the previous years, is now smelling like coffee even if there is no water in it) which ended up in an hour walk through the suburbs and I acually enjoyed having gotten my hair wet like this, it has been ages ago since that happened. Today (Sunday 07:00, DST stopped here today so I have one hour more today) it is dry so far but still a 40% chance of rain.
So what is on the menu for today? First I want to have breakfast because I'm hungry like a wolf, then I'm going to find a place which will rent me a bicycle so I can cycle over the Golden Gate bridge, buying some more socks and then I will meet up with some people of the FreeBSD project.

In the next two weeks I will be on training for my new job at Riverbed in San Francisco and Sunnyvale. It will be two courses, Steelhead Appliance Deployment and Management and Steelhead Mobile Client Installation and Configuration.
A Steelhead Appliance is a device in your network, one centrally at your servers and one or more remotely on the user LANs, which provides WAN optimisation, WAN acceleration and Wide Area File Services. Or in plain English: It makes the data over your networks be transferred faster.
The best comparison for it is your webbrowser: When you initially a page with images, it will download them all from the webserver and store them in a local cache. If the next page you go to refers to these images, it will just use them from the cache instead of downloading them again. That is Wide Area File Services.
The next one, WAN optimisation, is the HTTP protocol. The old version setup a new TCP session for every HTTP request, the new version can continue on an earlier used TCP session.
And the last one, WAN acceleration, is compression of the static HTML pages by the webserver: Compressed data is often smaller, so it will be there faster.
The Steelhead appliances don't only work on the HTTP protocol, but also (including but not limited to) with CIFS (Windows File Sharing), MAPI (Exchange server), NFS. And for protocols it doesn't know about, it will still do compression.
That is the hardware version, which works on your WAN/LAN infrastructure. There is also the version called Steelhead Mobile for on notebooks computers, it will give you, at home over a VPN for example, the same performance boost as you have on your LAN at work.
Like I said, the first week is training, the next week is for getting my troubleshooting experience. From what I've read up so far it is pretty technical stuff I will get trained with, so it can't be all bad :-)
If you are in San Francisco between 2 November and 9 November or in Sunnyvale between 9 November and 14 November and want to meet up, drop me an email!
