Post Frisco

  • Bicycle up to and over a fog covered Golden Gate bridge, pretty awesome downhills!
  • Eaten at a relative’s french gourmet food (not expensive!) – it’s name is: sous beurre. It is up on 24th mission street together with a cafe called sugarlump.
  • Went to great coffee place called: Sightglass Coffee. Real, good coffee with flavour. 
  • Also went for breakfast at an awesome American breakfast by Chinese folks. Don’t think I’ll find it again though :) I may want to give it a try ;) It was Golden!
  • Lots of walking around the hills, no car chases yet though.
  • Many other conferences happen here, quite often it seems. For example Intel’s IDF which was over yesterday and saleforce’s cloud computing (next week).

Android wordpress publishing app

Enabled! Wonder if there’s been lots of exploits for this method of writing posts?

Turns out there are lots of old exploits for wordpress and xmlrpc, apparently it may also leave the page open for bruteforce attacks.. I’ll leave this one disabled.

But I bet there are other ways to upload posts. E-mail perhaps. But it’s actually working pretty well with google chrome — at least it’s a lot smoother than the native android browser.

Thoughts after Brocade’s Analyst and Technology Day 2012

Thursday today, the day after the Day. It was a real long day, and to my surprise it said ‘press’ on my pass – so I had to try to ask some questions :)

Some things picked up:

* New VDX 8770 product released – a modular Ethernet switch. Room for 384 10GbE ports. 100GbE ready and also ready for SDN protocols like VXLAN (vmware) and NVGRE (windows 2012). The VDX 8770 chassi is called “Mercury” internally in Brocade. I found it very similar to the DCX chassis  except that the supervisor modules are half-height.

* Today Brocade opened up registrations for the BCEFP certification – Brocade Certified Ethernet Fabric Professional (which include the VDX8770), It looks advanced and you probably want to take the previous exam – BCEFE – before.

* SDN – storage-defined network was the main focus of the day. Fibre Channel was barely mentioned at all.
Ken Cheng‘s (one of the VPs of Brocade) definition of SDN:

“A set of technologies which are focused on achieving three objectives: network virtualization (vxlan), programmatic control (openflow) and cloud orchestration (openstack).”

It was quite obvious that Brocade’s VCS is the technique/medium which they intend to enable these new technologies. SDN is still quite immature (even though internet2 are already using it in their production network) – so be prepared to wait if you want ready solutions.

* VCS seems quite similar to QLogic’s/Juniper’s QFabric. They had a hands-on lab where we could connect four smaller vdx switches and a vdx8770 (4-slot version). The switches had only had a unique ID set on them and their were end-devices (web-servers, web cams and a tablet) on different IP subnets on each switch. All I needed to do to connect switches (and devices) was to connect two switches via a fibre pair. Quite easy. Almost too easy to be true. This is something I really enjoy that’s part of Fibre Channel. The technology has quite a few features, self-forming trunks being one of them (with frames being striped over all members of a trunk). It also gets rid of spanning tree (so no more unused links).

* Quite soon we should see Brocade’s OEMs release embedded VDX switches for their blade chassis. No news yet about which but lately IBM have been quick to release new Brocade products. As a side note: Brocade from start only sold their gear through OEMs, this is no longer always the case and they are trying to communicate more directly with customers.

* Cost per bit was really important to push down for internet exchanges.

* It’s a lot easier to write a blog post on my wordpress blog via Chrome (on android) than via the native browser. Using my asus transformer tf101 as a note taking device for the day worked out great. Success!

Hello Silicon Valley!

Checked in at the hotel, mighty fancy one, it has a pool :)

Weather is great down here, much warmer than in San Fran. Hotel is basically right next door to where I’m heading tomorrow and it looks like there’s quite a lot of people coming!

Cisco is right next door to, gotta go snab some pictures while I’m here, may not get any time off tomorrow.

Lots of lunch places next door too, I was afraid it was going to be in the middle of an industrial area.

And a bonus picture has been taken, but I appear to be having some issues inserting it into the post..


Trip to San Francisco

Made it through flights and security checkpoints and buses and trains!

Next time I’m going on this long flight it woud be awesome to actually bring tooth paste and tooth brush in the hand luggage. Also possibly some own food in case the air plane food is not so awesome. And some water :) Besides that the hoodie, sleeping/eye covers, scarf and Kindle and head phones were enough.

Weather is way better here than in Helsinki :) Pretty cool to get to see Greenand from above with no clouds, also Yukun is pretty impressive. But the farmlands of USA are pretty cool too – so structured and organized.

So what’s a good way to get rid of jet lag? Tomorrow I’l see if a bike ride is it :)

The hostel I’m in is the same as in 2008 when I was here last time  – although this time there’s way more folks hanging out in the “social room” – but all people do is play with their phones and tablest/computers.. maybe because it’s Sunday people chill out a bit more.

Asus Eee Pad Transformer TF 101 + root + arch in chroot

Just got one of these – thought it would be a great tool when going to conferences for example or somewhere where I would need a small computer but don’t want to bring a long my normal heavy laptop.

Normally I prefer pen and paper when going to meetings or conferences, but if there’s a lot of information needed to be written down or if I want to check something online it sounds quite nice.

Got a keyboard with it too. The stuff I’ve wanted do to so far works perfectly and it is very nice to play around with – though I haven’t done any serious work or task for any longer period of time yet. If I can do that without any/much issues I will be very happy about it.

Rooted it without any problems (from a Windows 7 x64 PC). Needed to install the USB drivers from Asus’s page –  (choose OS android).

It would also be nice to have a Linux chroot terminal running inside Android. This tutorial works pretty great – at least to get a basic setup :) Still need to play some more with it to get things working (vpn perhaps?). After you got the sshd running on the android you can connect to localhost with an ssh client, for example irssi connectbot. In there you run the commands outlined in the last link.

After you create a user you need to add the user to the appropriate group. At least if you want network access.
What was strange was that if my user was in only aid_inet I could ssh and irssi to an IP-address, but I could not ping said address. Neither could I ping or ssh to a dns-name. After adding group aid_net_raw and your user to that group that was possible.

After that you can use ‘pacman -S irssi’ to install for example irssi!

Happy transformer arching!
