Tom Friedman at the Freedom to Connect Conference

I’m at the Freedom to Connect conference, Thomas Friedman gives a keynote speech drawn from his latest book Hot Flat and Crowded. Notes:

Khakis, white shirt, tie. Looks shorter and younger than I expected. 🙂
Turns out he lives in Bethesda, so it is just a quick ride on the Metro.
Based on his book Hot, Flat and Crowded.

Looks at the running chat — “What the f*ck is that?”

Takes off shoes.
Someone immediately posts a photo on the interactive chat.

Motivation to write the book was that “we lost the groove of our country”.

New unit of measure — the Americum == 300 million people living like Americans

First Law of Petro Politics:

Price of oil has an inverse proportion to the pace of freedom.

Moderated a panel between Al Gore and Bono.

According to the World Bank, 1.6 billion or 1/4 of all humanity have no access to electricity.

Loosing a species every 20 minutes. We are experiencing the biggest loss of biodiversity.

An incredible list of opportunities masquerading as a series of disasters.
Solution to the problems of climate change, poverty, (and everything else) is abundant cheap reliable energy.

The country which dominates energy technology will be the leader going forward. This country has to be the U.S.

You’ll know it is a revolution when somebody gets hurt.

American golfers get 41 miles per gallon, based on the number of miles walked per year (900) and the average amount of alcohol consumed. (22 gallons) (LK: does this statistic factor in the lower efficiency of ethanol?)

The difference between technology and commodity.
Wind, nuclear solar, etc. are technologies == the more used the price goes down.
Fossil-fuels are commodities. == the more used, the price goes up.

Change the leaders, not the light bulbs.

When we leave Iraq it will be the biggest transfer of air conditioners known to mankind.

BANANA = build absolutely nothing anywhere near anything

Smart grid –> Smart home –> appliances automatically day trade electricity — stores power in electric car battery.

The future is here it is just not widely distributed yet.

I love being a reporter. It is a noble craft.

Conference: Freedom To Connect


Another plug for the Freedom To Connect conference to be held in Washington DC March 30th and 31. To crib from the home page.

F2C 2009 will tell the story of:

  • on-line, network-enabled industry and culture, new jobs and sustainable growth
  • Burlington VT, where muni fiber enables business, artistic endeavor, and new telemedicine
  • how Lafayette LA’s community came together as it built its muni fiber network
  • the twin cities of Cedar Falls and Waterloo, Iowa, where one twin has a muni net, and the other doesn’t
  • how municipal CIOs are planning for Seattle, Portland and San Francisco municipal fiber networks
  • city nets, wired and wireless, that didn’t work — what went wrong and what that teaches
  • what Obama’s infrastructure and economic recovery plans mean for tomorrow’s network

Revisiting

After more than two years, a former and much loved non-profit client called for some help in sorting out their donor database. That’s another story which may be worth telling, but I was interested in seeing how they have weathered the economic downturn, and how some of the networking decisions that we took some years ago have held up. They have a main office and several field offices scattered among three counties. They have about 55 employees.

  1. By the time I had left, most of field offices had a broadband connection. That work was completed, and each office now has a DSL broadband connection, either from a local ISP, or from Fairpoint (the company who bought the Verizon landline and consumer data service in the three northern N.E. states). After working with it for a couple days, I’d say performance is OK.. although today, curiously, there was a twenty minute outage.
  2. With broadband available, they how have remote access software going to EVERY computer in EVERY office, as well as their central file server. Much desktop maintenance that required an on-site visit, can now be accomplished over the wire.
  3. Electronic mail accounts are hosted by the local internet service provider. People use Outlook or Outlook Express as their desktop eMail client….and access their eMail account when away from the office via webmail.
  4. They refreshed their desktop hardware with Dell Optiplexes that were donated by a local large employer. Although the machines are hand-me-downs, they are more than adequate for eMail, web browsing, and running the database application. The donor also gave them several laser printers that were only a few years old. Everyone is running XP, with Office 2007. (Without prompting, they said that Office 2007 is fine.) They have Norton Anti-Virus which is managed from the file server. No less than three of the staff said, in casual conversation… “well, I do have a Mac at home”. I nodded toward my Macbook, running Parallels, wondering if this turns out to be a longer term gig, if I will need to get a new Windows laptop.
  5. Their Dell file server is probably going on five years; but it is built like a tank, with RAID drives, and the original HP backup tape system. They have HP Procurve 2124 ethernet switches, and HP continues to keep replacing them under a lifetime warranty, when the fans go bad. I think we’ve replaced two or three switches with this client, and a couple of them with other clients. It takes one phone call.
  6. Several old battles were, well, old, if not forgotten. They have made their peace with a state-mandated performance data application which gave us all fits for years. The Executive Director attributes this success to attentive support from the state agency which mandated the system.
  7. If there is one especially popular non-business application being used by the staff, it is streaming audio. In fact, today, the first indication that there was a glitch in the internet connection was when a staff member came in and asked why her “radio” wasn’t working.

In short, it Just Works. I think this is attributable to the existing staff who have educated themselves over the years, and new staff who have come on board with full expectations of a functioning network and desktop workstation and how to use it. Add in some longstanding support from management who recognize the value of investing in technology and training, and the efforts of the current part-time network manager who keeps it all humming.

NPower – Network Documentation Template

NPower Seattle has a Network Documentation Template which is in Word. This is a great start for documenting your computer network. The file is called SBS2003template.doc which suggests it might have been modified by one supplied by Microsoft, and it includes inserted Visio files to show the networking diagrams. If you are a MS shop this will work out of the box. If not, you can easily modify it in OpenOffice, or Pages, or whatever. The object of documenting your network is not necessarily perfection…but to have something to give you a clue when things start going haywire.

Email Transition: Verizon to Fairpoint

All of a sudden I’ve lost eMail contact with lots of friends who had verizon.net eMail accounts as Verizon abandons their landlines in three New England States, and Fairpoint takes over.

There is an official site provided by Fairpoint which will help people transition… but it is for Windows only. The site checks to see what your browser and operating system are, and if you have Windows XP or Vista, and are using Outlook 2000 or later, you can download a little program (ActiveX control) which will change your settings.

If you don’t use Internet Explorer, the automatic setting won’t work. The manual instructions are on the next page of the web site. I had a friend go through this with a technician, and this is what he came up with.

User or Account Name:
Your new myfairpoint.net email address
Example: ([myusername]@myfairpoint.net)

POP Server: mail.myfairpoint.net (i.e. incoming mail)
SMTP Server: mail.myfairpoint.net (outgoing mail)

Account name – on incoming mail server
[myusename].myfairpoint.net

Check My Server Requires Authentication
Settings next to it. “Use Same Settings as Incoming Server”

The technician also suggested that you change the outgoing mail port change from 25 to 1025 (WTF?)

I do have Fairpoint phone mail, and this no longer picks up when I’m on the line. Sigh.

If you have anything non-windows, and non-IE (Linux, Macintosh, Safari, FireFox) , you have to use the manual instructions.

Tech Friday: Small Business Network

In a recent column  Jerry Pournelle talks about problems with the Microsoft Active Directory.  

Back in 1999 I set up the Chaosmanor domain with Active Directory on two machines running Windows 2000 Server. I knew at the time that I didn’t need that complex a network, but a number of my readers did. In those days networking was hard, Active Directory was new, and many of my associates were curious about how well it would work. At worst this was another of those silly things I do so you won’t have to.

Actually, it worked pretty well. Windows Server 2000 with Active Directory had some infuriating requirements, and it really wanted everything done precisely its way, but from 1999 until this year it served me well. When Windows Server 2003 came out I was tempted to upgrade to that, but there was never any powerful reason to do so, and as time passed it seemed less attractive. I had novels to write and other work to do. I was able to try several Linux-based on-line backup systems – Mirra was one of them – and those worked just fine. Of course machines were getting better, and my old servers were getting more obsolete each year.

Now he thinks that everything he knew about networking is wrong. In particular, like many of us, his experience carried over from older versions of Windows networking, which makes things a lot more complicated than they need to be these days. You can reads more about workgroups, domains and routers and alternatives to Windows networking in the column.

At Microdesign we are reevaluating our own network, that has a core server running Windows 2003 Small Business Server; i.e. relatively unchanged for the past five years. Nothing has really changed as far as our core requirements are concerned, except there are several of us working from different offices, and on occasion when traveling. We increasingly collaborate on projects with partners who are outside our company. Our requirements parallel many small businesses and non-profits with 2-50 computer users. Here are our “legacy” requirements:

  1. Common file sharing area where multiple users/machines can access the same document
  2. Absolute trustworthy security of those files
  3. eMail and calender – available from anywhere on multiple devices
  4. Shared printing, from multiple machines to single printers.
  5. Reliable backup 

Those modest requirements suggest a file and print server based in the office, connected permanently to the internet, with printers shared off of the file server, and some kind of backup scheme (tape or additional hard drive). The network diagram which fulfills these requirements is essentially unchanged from the 1990’s.

Even with a server-centric network our advice to clients has always been to use the facilities of an internet service provider for two applications; eMail and the outward-facing (public) web server for the organization.  We (still) recommend having eMail outside the organization to provide greater reliability, ubiquitous access via the web, and industrial-strength spam control. We recommend the organization’s public web site be hosted outside the organization to provide 99.99% uptime, and to take advantage of higher bandwidth typically provided by an hosted provider. 

So, what has changed? Two things; disk storage and broadband. Broadband, or rather cheap broadband, has made it possible to reconfigure things so that the cloud  can now substitute or supplement a file server. With individual personal computers routinely having disk drives of 250 gigabytes or larger, the original justification for “server as giant hard disk” is falling away. 
Along with hardware improvements, there are now a host of inexpensive applications available on the internet that can supplement or replace software that used to require a file server. Basecamp is one example that can be used for project management and shared file storage. 

A more modern interpretation of the legacy network diagram puts the cloud at the center of the network.

So, I’m wondering whether to replace my file server. The server is no longer the be-all end-all of my network. Like Jerry, I don’t need a domain login mechanism. I barely use my printers, and those are attached directly to the local network. The small business server’s eMail, and web hosting have always been done off-site. The server does offer SharePoint, which is a capable platform for Basecamp-like project management, but Basecamp is about $12.00 per month, and it took about five minutes to set up. And, now that we have been invaded by the Macintosh monster…there are more reasons to find, (or at least evaluate) a cross-platform solution for our application needs.

MobileMe – Synchronizing Macs

I’ve been intending to sketch out my whole synchronization scheme which keeps multiple applications synched between two Macs and the rest of the world, but it is so complicated that just documenting it has made me want to rethink. In the interim, I noticed yesterday that a bunch of changes that I had put into my address book on the MacBook didn’t get synched to the iMac, and after a lengthy chat with Apple’s MobileMe tech support the answer appeared to be nothing more than logging out of MobileMe on the laptop and then logging back in.

One trick with synching with MobileMe is to strip down the applications, so that you are only trying to sync one thing at a time when troubleshooting. Right now I’ve only got the contacts synching.

If one forgot that you can actually log into your MobileMe account from a web browser, one should be reminded of that helpful suggestion, as you can check whether your sync changes reach the the “cloud”. Obviously (in hindsight) if you make a change in iCal on one machine, and do a sync, the changes should appear in the copy of your files in the cloud, before any other machine can sync and download the changes.

Windows vs. Linux – Open Source vs. Commercial

I got sucked in to a bit of back and forth on our local Linux/Unix list a couple days ago and wrote:

Ten years ago I was consulting for a multi-national education non-profit, and I discussed with the systems manager the notion of using open source…in particular I was talking about replacing their Windows 2000/NT servers, with Linux. This would have been a logistical wrench, not least because they had several client/server applications that used SQL-Server as the back end. His point was that as an educational institution, they got such good discounts on any proprietary software that the amount spent on the software was a miniscule percentage of their IT budget. So, there was no economic benefit, and certainly no performance benefit that justified such a change.

Later that year I was doing an inventory of their machines at one of the european sites and couldn’t find the terminal server box. Turns out this was a Linux box running VMC or something and it had been bricked up in a wall during a recent renovation, and been merrily running, unseen, for several months.

So, the moral for me was, use what works. At the time I actually got them to go from running four O/S’s in the organization to two, Windows, and the aforementioned Linux. We dumped Macs in one site, and Novell in another, and my advice to subsequent clients was to run one and only one OS in the organization.

I’m happy to say that they didn’t all run Windows.
