Both LinkedIn and Twitter have been rolling out "enhancements" to their interfaces to make them look, feel, and behave more like Facebook. I'm already suffering from information overload, so giving me even more places to look for and access even more information than I already have seems to me to be more like a bug than a feature. And Facebook fails utterly at coherent interface design, so the mad rush to be "just like Facebook" really is a bug, not a feature.

After Hurricane Sandy, cell phone networks in the affected areas were, by and large, not working. Like the situation after Hurricane Katrina, many cell tower sites had no long term back up power source (i.e. a generator), fuel to keep generators running was not available, or generators were flooded out because they were installed on the ground. In the New Orleans area, it was not the storm that took out networks, it was the flooding. As flood waters rose, the high water drowned the generators, power failed, and the networks went down.
This is not rocket science. Fiber and wireless networks can be engineered to be as reliable in a natural disaster as the old telephone network, but it requires spending money in the right places at the right time (i.e. before the disaster).

Business Insider reports that only Apple, Samsung, and HTC are making any money manufacturing and selling smartphones. All the other makers, including RIM, Nokia, and Motorola are losing money. This means that the cellular companies are able to buy most smartphones for less than the cost of making them; this is called a death spiral. This may explain why Google is trying to prop up Motorola; if they don't, the only Android company left standing is Samsung, which then effectively has Google by the short hairs.
The whole cellular marketplace is a tightly knit mess. As more and more people switch to smartphones, more traffic, often by several orders of magnitude, is dumped onto the cellular networks. With traffic doubling every two years, it means that the cellular companies have to keep dumping more money into upgrading and replacing radios. And pushing smartphones onto their customers accelerates the process.
The vision of a world with "big" broadband provided by the cellular companies is just that: a vision...induced by smoking giant bongs stuffed with baloney. Cellular networks are essential infrastructure....for mobility access. And in a few areas, they serve as a barely adequate stop gap for the lack of fiber connectivity.
But communities need to be playing the long game. If you want to believe you can hitch your community's economic future to wireless, go ahead. But with hundreds of communities now making investments in fiber, trying to attract businesses and trying to retain your existing businesses with the notion that wireless is secure enough and affordable enough for serious business use is weak tea....don't smoke the baloney.

Apparently some IT firms did not study the lessons learned from Hurricane Katrina. What took out most of the phone system and the broadband/Internet networks in and around New Orleans was not the high winds and rain, but rising waters. Many of the network electronics were on high ground (e.g. upper stories of buildings, above flood waters), but the emergency generators were on the ground! The water rose and flooded all the generators, and the networks went dark.
So in New York, the same thing is happening. Major Web sites are going dark because data centers are having power and flooding problems. Anyone that puts a data center in a flood zone (and lower Manhattan is a flood zone) is nuts.
The second lesson from Katrina is that you may need all your data and servers fully duplicated at another location somewhere well away (e.g. several states away) from your primary server location. If the Huffington Post Web site is dark because of power problems in New York City, that tells me they don't have a disaster recovery plan.
As more and more stuff is stored online in "the cloud," there is a growing demand for data centers, and data centers that are away from coastlines, away from flood and hurricane zones, and near high performance open access fiber networks have a distinct advantage.

The storm of the century may have blown over by November 6th, but if power is still out in some places in the northeast, I wonder what the Plan B is for voting if all the local governments have are coal-powered (i.e. electric) voting machines? If all the old manual voting machines have been recycled for scrap, how will they handle the power outage? If they still have the old manual voting machines in storage somewhere, do they have a well-designed contingency plan to haul all those machines to each voting precinct and train the poll tenders to set them up and use them on short notice? If there are no manual voting machines, or if there is not time to get them all moved to the precincts, do they have a paper-based voting system ready to go that can be verified and audited?
Just because you can use a computer to do something does not mean that you should. The convergence of the storm of the century and a presidential election may well expose the weak underbelly of our excessive reliance on electronic gadgets for things that could be done with virtually fail-safe mechanical or manual systems that work even if there is no power.

Apple introduced the new iPad mini yesterday, which is an incredible piece of engineering, but to me, the more interesting story is the release of the new iMacs, which seem impossibly thin, largely because Apple has eliminated the DVD drive. Apple has always led on storage media, and the company has a long history of pushing the entire industry in a new direction, including 3.5" floppy drives, CD-ROM drives as standard, DVD drives as standard, solid state drives as standard, and now, elimination of removable media entirely.
The story behind the story is broadband. Only widespread availability of broadband has made it possible to eliminate removable storage from our computers. Apple's Mac App store and the Web have made it possible to buy any software you need directly from the 'net, so who needs a DVD drive? The interesting side effect is that broadband is green....really green. Eliminating hundreds of millions of DVDs also eliminates the cost and energy of manufacturing, storing, and shipping those DVDs. While it is true that data centers storing our content in the cloud use energy, at the same time, broadband and the cloud are eliminating lots of other energy uses.

If you are interested in seeing firsthand what happens when a city invests in open fiber, there is still time to register for the Broadband Communities Community Fiber Networks conference in Danville, Virginia in early November. Danville's open access fiber network has been a key part of an enormously successful downtown revitalization effort that has brought hundreds of new jobs to the community and international firms have been re-locating to Danville in part because of the high performance, low cost open access fiber network.

A MOOC is a Massive Open Online Course. These are online college classes that often have enrollments of many tens of thousands of students in a single class. The concept was pioneered by Harvard and MIT in a joint project called edX, and with the University of Texas joining edX, the movement is going to expand dramatically.
With the cost of a college education now costing many tens of thousands of dollars a year, most college students can't get a four year degree without nearly bankrupting their parents and/or taking on staggering student loans. And employers are not always satisfied with the quality of college graduates as many four year institutions have been spending more on amenities to justify the high tuition while shortchanging actual instruction.
MOOCs have the potential to make getting a good job much less expensive, and the traditional four year colleges had better beware....the dis-intermediation is being caused by high speed broadband. Like the sudden disappearance of music stores, which took only ten years, expect many four year schools to be gone a decade from now, as parents and young people figure out that there are cheaper and better ways to get prepared for the work world.

You can now buy the new Logitech HD video camera, called the TV Cam HD. The device combines a high resolution HD video camera, integrated four-microphone sound input, and Zeiss remote control zoom lens. The breakthrough is that Skype is built in, meaning you don't need a computer. The camera can work with your home WiFi or Ethernet network, and an HDMI jack plugs the video and audio right into your existing flat panel TV. The camera also has a built in ringer, so that solves one of the persistent problems with using Skype as a phone replacement...your computer has to be on and awake all the time to be available for a call.
I just had a friend with one of these cameras call, and I can attest that the picture quality, over the network, is really excellent, and we use Skype with webcams on a daily basis...this new device is clearly better.

I seem to have crossed some kind of spam tipping point over the weekend, with more spam hitting my Inbox than is being filtered out by two levels of spam filters (one on the server, one on my mail client). There was a time when as much as 90% of the spam was being caught by this two-level approach, but no more. I'm now getting only about 50% of spam trapped by the filters.
Spammers are using two techniques to foil the filters. The first is the relentless use of zombie machines that have been infected to send out email from apparently legitimate source email addresses; they do this so the filters can't "learn" origination email addresses and block them. The second is equally pernicious; they are using increasingly sophisticated phishing techniques to create emails that look exactly like the messages we get routinely from legitimate companies. For example, over the past several weeks, I have apparently ordered at least one thousand large screen TVs from Amazon. The order confirmation message looks EXACTLY like the legitimate order confirmation messages I receive from Amazon. So I can't mark these emails as spam, or the occasional real message will be blocked. I get these phishing emails from US Air, from American Express, from Verizon, from AT&T, and many other companies.
This is a slow motion catastrophe. I would estimate I am now spending as much as 45 to 60 minutes per work day just reviewing and deleting spam from my Inbox. I can typically tell from the subject heading, but it takes me as much as thirty minutes in the morning to delete some 300-600 spams, and then additional time every time I check my email during the day.

Gmail can now read many kinds of attachments. It is touted as a benefit to users, as a Gmail user can search not just the text of emails, but also the text of attachments stored on Gmail. But it also means Google will be searching those attachments as well and using the information it finds to fine-tune the kinds of ads it delivers to you.

Chattanooga is providing financial assistance to people with technical backgrounds who agree to buy a house and move to the area. It's a brilliant idea, and coupled with their fiber network, Chattanooga continues to prove they are not just serving up the same old warmed over, forty year old economic development strategies.

Via Slashdot, here is a link to a new book that talks about why Internet and broadband in the U.S. is so poor. It's worth a read....basically, all the money has been spent on mobile cellular networks and not on local fiber infrastructure. And adding to the problem, in most markets, there is cartel pricing via the telco/cableco duopoly. Residents and businesses have only two choices: marginal DSL or cable modem service that won't support now-common business services and applications.

Apple pundits, prior to the release of the new iPhone 5 yesterday, were saying that the new device would be no big deal because Apple had nothing to add in the way of features. In a way, that's true; there is nothing like the iPhone 4S release of Siri, the voice input software. But Apple kind of busted through the old engineering joke: "Quicker, cheaper, better: pick any two." Apple has managed, with the iPhone 5, to offer a phone that is faster, lighter, and thinner: customers get all three! Apple is saying this is the best iPhone they have ever built, and I believe them. Not only did they make the phone and the screen bigger and brighter, they also managed to make the phone thinner and lighter. That's quite an achievement. And it is truly a world phone; it supports just about every cellular wireless protocol on the planet. They speeded up the processor, speeded up graphics, and speeded up WiFi networking.
My iPhone 4S is barely a year old, and I'm already looking longingly at the iPhone 5.

Amazon has released its new Kindle HD, and it is really something. It's nice to see someone giving Apple some real competition, rather than just copying what Apple does (cough, cough, Samsung...).
The original Kindle Fire was a bit underpowered, and seemed to be primarily a conduit for selling Amazon content (as well as being a decent book reader). But the Kindle HD, while still a conduit for Amazon content, has a more refined interface, improved graphics, improved processor, and better connectivity (better WiFi, 4G cellular support). But the new Kindle also supports Skype, better email, a very interesting set of parental controls, and an improved Web browser. Finally, Amazon is touting support for college textbooks, a direct swipe at Apple's similar iBook initiative.
This is great for consumers. The Kindle HD now appears to be a much more capable tablet device that can go head to head with the iPad. And it is no accident that Amazon released it just days before the rumored iPad mini.

According to a Bloomberg report, Apple is finding it difficult to re-imagine TV. Content providers are scared to death that Apple will be successful in creating a better TV experience. The problem is that the cable companies are deeply involved with the content providers...recall that Comcast, as one example, owns a big chunk of NBC. The cable companies have decided to go down with their own ship; they are going to cling to the sixty year old analog cable model until their last customers swim away the S.S. TitanicCableCo.
I can't really figure out what Apple has in mind that hasn't already been done. I've already ditched cable TV, and am quite content with cheap Hulu and Netflix subscriptions. Why do I need to buy a box from Apple? It's not that hard to bookmark the Netflix site and click on something in my queue. This is one area where I don't Apple really can bring some fresh new user interface experience a la the iPod or the iPhone and win.

Here's another report on backlit tablet devices and how they disturb your sleep cycle. The Kindle does not cause the same problems, as it uses the reflective e-ink technology.
Update: I was reminded by a reader that the Kindle Fire is backlit, so that is a device you should NOT be using at bedtime. The less expensive black and white Kindles are the e-ink models and do not have a back light.
Yet Another Update: Amazon just released a new Kindle Paperwhite and Paperwhite3G....with higher screen resolution....and...a backlight! They even have a picture of someone reading in bed in the dark using the backlight. Somehow they forgot to mention "Warning: use of the backlight before bedtime will keep you up all night."

The clash of the Titans is on....Netflix and HBO are taking the gloves off in Northern Europe. Both content companies are ditching cable and satellite TV to offer their movies and "TV" shows as IP-TV offerings. No cable or satellite TV subscription required. Meanwhile there are bunches of small start ups that are negotiating "channel" line ups for a pure IP-TV offering; their plan is to offer bundles of niche channels (e.g. The Food Channel, the Golf Channel) at a very low monthly subscription price. Once subscribed, you can pick out any show you want and watch it anytime you want, much like Hulu.

Sometimes little things can have big impacts. The BioLite HomeStove has the ability to make a lot of lives better while reducing tree loss in many parts of the world. The innovative cooking device is a highly efficient "jet" or "rocket" stove that burns small amounts of wood while generating a lot of heat. There are many similar jet stoves, and because they are so good at creating lots of heat quickly, in many impoverished areas, the stoves can dramatically reduce the amount of wood needed to cook food, and make it possible to sterilize water much more easily. The stoves also reduce the amount of work needed to collect wood, which, if you are cooking for a family over an open fire, can be very significant.
But the real innovation of this device is the integrated thermocouple that powers a small fan (to make the stove more efficient) and powers a USB port that can charge small portable devices like LED flashlights and cell phones. It is an amazing innovation that has the potential make millions of lives better.
