Paris, France

2010.10 Photos of Paris, France

Like any large city, Paris changes a bit with every visit. The bicycle is back, mostly in the form of VĂ©lib’. Wifi in the parks is pretty cool (though frustrating to try to use with an iPhone) and though your batting average for a good cafe is never in jeopardy, yelp and other services give you a pretty good idea if you will like the menu before you even arrive.

But the things Paris is famous for haven’t really changed – the food and sights are still the main draw in the worlds most visited city. We focused less on particular goals for our 6 days, and were much better for it. The boulevards are gorgeous to stroll, the farmers & street markets are perfect to pickup a meal, and one can do much worse than simply sitting in a park to enjoy the sun.

SSH to an AWS EC2 server from an iPhone

The first round of SSH clients for the iPhone presented some problems when connecting to Amazon Web Services EC2 Linux server instances. EC2 instances require a private certificate key file to be used to authenticate to the server during an SSH session. This lead to some workarounds where one had to export the iPhone’s key and add that key to the EC2 server instance. This wasn’t much fun to do. Thankfully, the latest versions of many SSH apps for the iPhone support private key imports. For my example bellow I’m going to be using the iSSH app:

1. Find the .pem key file saved during keypair creation in Amazon Web Services for the instance you launched.

2. Get the the content of the .pem file into the iPhone’s copy/paste memory. There are several ways to do this, here are two of them:

– 2a. Save the pem file to dropbox and open the file on the iPhone using the dropbox app (note you likely need to rename the pem to .txt in order for iOS to allow you to read the file).

– 2b. Open the .pem file with a text editor and copy the contents into a new email to an iPhone account

3. Open iSSH, go to General Settings -> Configure SSH Keys -> Import Key…

iSSH home screen

4. Paste the content of the .pem file into the lower text box; ignore the Key Password field unless you have specified one when generating the key separately (Amazon keys don’t typically have passwords).


Save the private key file

5. Go back to the iSSH home screen and select Add Configuration…

6. Select the Use Key and select the key file saved earlier.

7. Save the configuration and connect to the server instance.

IT service administration apps on the iPhone

Stuff breaks. Usually when I’m nowhere near a computer. These 4 apps help keep me sane:

1. Jaadu Remote Desktop (app store link). Pricey, but the best RDP client of the bunch. This plus the built in iPhone VPN client and I can access all of our Windows based servers.

2. Citrix Receiver (app store link). Only really applicable if you have significant Citrix investment (e.g. Citrix Access Gateway), but this app works great for a quick check on things in our hosted environment.

3. iSSH (app store link). Great SSH client for the iPhone. The private key import function (copy paste pem contents) is critical for using this app with Linux servers on Amazon Web Services.

4. iAWSManager (app store link). This is a fantastic app if you are heavy into Amazon Web Services. There is an amazing amount of functionality packed into it – CloudWatch monitoring graphs, EBS manipulation, security group access, etc. Given the choice, I won’t be launching new EC2 instances from the app because of the screen size, but it is amazing to have the option.

Sturtevant Falls hike

A month back we did a new (to us) hike to Sturtevant falls in Angeles National Forest. The trail head is at Chantry Flat, off Santa Anita Avenue in Arcadia. From there it drops down into the darkest and most lush SoCal valley I’ve been to. Black oaks tower overhead as you walk past tens of cabins along the dammed creek. The falls were nice, even at their dry point during the year. I can imagine that the upper pools would be quite large in the spring. We did the total hike in about an hour and a half, the only crappy part is the climb back up to Chantry Flat. Well worth the time if you are in the area.

Scuba diving Los Cabos (Cabo San Lucas)

During our visit to the tip of Baja we enjoyed two days worth of diving. The first day of diving we stuck to relatively easy local sites. The first dive was at Pelican Rock, site of the famous (or not so famous?) sand falls. The sand falls were a mild curiosity for me, much more exciting were the huge schools of fish circling the rock walls. There were several large groupers hanging around, but none would let us get very close. Near the end of the dive we were able to get up close to some of the tangs, box, and butterfly fish that hung out around the rock’s walls. The walls are covered with some impressive fans and anemones and the site looks quite healthy. One thing to note – stay on the bottom until you are ready to join your dive boat as there is massive amount of boat traffic in the area. When we started the dive early in the morning we were the only boat around. When we finished and came up there were about 10 other boats anchored within a stones throw away.

The second dive was on a wall just south of Pelican Rock. The wall was interesting, but again the shallow critters were a bigger draw. Large schools of fish, including large trumpet-fish were milling about in the 10-30 foot range around the rocks, snacking on salp chains that drifted into the area. The sand flats around the rocks were full of life as well – quite a few rays and guitarfish had buried themselves in the sand channels.

The second day of diving was much more ambitious. We did some more advanced diving on an open water sea mount known as Gordo Banks (or Gorda Banks). The depth of the mount is about 115′, so we used 28% Nitrox for both dives. This site is known for the chance to see large open water critters like sharks, mantas, and tuna. Unfortunately for us, the visibility was quite poor for both dives. The water was green and less than 15 feet of visibility from 20-100 feet. Under 100 feet it cleared right up, it was a bit like stepping out of a fog. We saw some very large jacks (people sized) on both dives, in addition to some large schools of fish. We caught a glimpse of a small school of hammerhead sharks on the first dive, but they were in the pea soup green above us, and we couldn’t catch up to them. It would be a great dive site with better visibility.

We saw a marlin on the surface during one of our intervals, and I hopped in to try to snorkel with it. I missed my mark or it didn’t like me – it was long gone. The trip back to harbor was against the wind and it took us several hours to get back to the harbor. Make sure you bring sea sickness meds if you think you might need them – several people fed the fishes, including our captain.

I think our mixed diving results have a lot to do with the strange weather patterns in the pacific this year. The water was much colder than they are used to (water temp at depth was 63-64F) and it seemed like summer wasn’t quite there yet. It definitely warrants another attempt when we make it back down again, you never know what you will see in the open water.
