Mythbusters paintball gun Mona Lisa

Posted by Kelly Adams on 28th August 2008

Adam and Jamie of Mythbusters fame are cool guys. I enjoy their program and find it oddly educational, in a sort of geeky-destructive way. But I have to admit that the following video of a demonstration they did at an Nvidia graphics card conference really impressed the heck out of me. The first part of the video shows their interpretation of computer graphics using a single CPU, and the second part is their version of a massively parallel GPU rendering.


Make sure you watch it through to the end- the first part is kinda slow, but that’s the intention :)

Star Trek Experience closing… what’s the point of Vegas now?

Posted by Kelly Adams on 7th July 2008

I was reading a news item the other day indicating that the Las Vegas Hilton is closing the Star Trek Experience in Vegas. This was one of the few things in Vegas, along with the fountains at Bellagios and the Siegfried and Roy Secret Gardens animal exhibit, that my wife and I actually enjoyed while we were there. But it was apparent when we were at the Hilton that they were barely putting any effort into the Star Trek Experience any more.

Optimizing Wordpress performance

Posted by Kelly Adams on 22nd June 2008

My blog doesn’t get a lot of traffic. It has never been referenced on Slashdot. No one Diggs me. Basically, folks who find my site do so via a search engine, more or less by accident, or are friends and family. The fact that my site has been here at kgadams.net for a number of years and I’ve made an effort to make sure I keep the search engines moderately happy means that I get *some* traffic: maybe ten thousand hits a month, more or less. Just so we are on the same page: many “moderately popular” websites get that many hits in an hour. Seriously popular sites get that many in a minute.

But despite the fact that my site isn’t generating massive influxes of visitors, I still care about performance. It bugs me when my main page takes more than a second or two to generate, or when my administration interface takes ten seconds to appear. So what do I do to improve responsiveness? Well, I visit another blog…

It’s a big ass table…

Posted by Kelly Adams on 2nd June 2008

Microsoft has been working on something they call “Surface” technology. Basically, it is a touch sensitive user interface, and it is usually demonstrated using a large, flat horizontal LCD panel… a table. I’ve had my doubts about the usefulness of this technology outside of a niche environment- but I’m ready to be proven wrong. That said, I find the following video pretty effectively expresses my doubts…

Faintly ironic…

Posted by Kelly Adams on 30th May 2008

I’m sitting here in front of my second computer, more commonly known as “Irene’s game computer.” It is going through the process of installing Windows Vista at the moment, for the third time in less than a week due to various hardware and driver issues.

I’m typing this on my Macbook Pro while Vista’s install process chug, chug, chugs away. My Macbook never seems to have off days- it always just boots up and works. On the other hand, Windows is far superior for games…

For the curious, the various failures of my wife’s game computer really had little to do with Windows or Vista. The hard drive failed, which was precipitated (I soon discovered) by a failing fan. A couple of days later, as I was installing the replacement fan, I decided it was time to install my hand-me-down video card into Irene’s computer. Unfortunately, her motherboard didn’t have a PCI-E slot, so I also had to install a hand-me-down motherboard. I didn’t have a copy of Windows XP at hand, so in went Windows Vista. Shortly thereafter, I realized that this was the infamous Asus M2R32 motherboard that can’t go into standby with Windows Vista: this of course frustrated me since I am trying to use standby mode rather than leaving computers on all the time as a compromise between my need for immediate responsiveness and a desire to minimize my energy waste. Thus I have replaced the motherboard and CPU, which has led to another OS install, which brings you up to date.

On the upside, when all this is over the secondary game machine here will have more or less tripled in gaming performance. Win!

Still, it is comforting to have something to blame for the situation, and Vista is a handy target :)

Another kick at the cold fusion dream…

Posted by Kelly Adams on 25th May 2008

Nearly 20 years ago, some scientists observed something that looked like room temperature fusion, or “cold fusion”. If such a thing actually worked, and generated net positive energy flow (I.E.: you get more energy out than you put in to start and maintain the fusion), the world could be changed in amazing ways. Unfortunately, no one, including the original scientists, has been able to reproduce the observations in the two decades since the original incident.

Until a few days ago, that is. Scientists at Osaka University in Japan have publicly demonstrated what appears to be a working cold fusion design. Better yet, it seems to produce positive energy flow. There is tremendous doubt and disbelief in the scientific community because the previous incident gave the whole concept of cold fusion a bad name. And I personally am doubtful: if cold fusion really works and uses materials that can be produced rather than some arbitrarily limited/rare resource, and if it produces positive energy flow, and if that positive energy is significant… once again, the world could change in amazing ways.

Cold fusion could, if it really works well, mean the elimination of petrochemicals for the generation of electricity. That by itself would, in any reasonable world, fuel a massive shift to electricity for powering our vehicles. And if cold fusion generators can be made small, safe, and simple enough to fit in a home, we could see a truly distributed energy grid. If they can be made even smaller, perhaps we could have a fusion power plant generating electricity in each of our cars. The humourous Mr. Fusion concept in the 80’s movie series, Back to the Future, could become something like reality.

Alternately, this could be another huge mistake, setting back the investigation of the real possibility of cold fusion for several more decades. Or it could actually work, but require such rare or hard to manage materials and produce so little usable energy that the resulting technology is little more than a parlor trick. I fear that one of these possibilities is much more likely than the optimistic alternatives.

Mad skillz with Construction Equipment…

Posted by Kelly Adams on 18th May 2008

I came across this post on Gizmodo today, with the following video:



Stripped by a Mechanical Shovel! - video powered by Metacafe

Years ago, when I still lived on an acreage, we had a delivery of bricks for the construction of our retaining wall. The delivery truck had a little crane on it, and the guy used the crane to drop the eight or nine pallets of bricks with elegant precision and near-total economy of motion. It was a small thing, but I doubt the worker realized just how impressive his skill was. Likewise, we had a fellow do some Bobcat work on the front half-acre of our yard, and there was nary a missed step as tons of dirt was shifted and ground levels adjusted to control the flow of water across our property. The merger between human and machine was nearly poetic.

I admire the skills of these ballet masters of the mechanical- a testimony to the ability of humans to turn the mundane into something of beauty.

Is NASA playing with global temperature statistics?

Posted by Kelly Adams on 2nd May 2008

Liars, damned liars, and statistics. Apparently, several of the most “reliable” temperature recording surveys in the world indicate that the Earth’s average temperatures are actually showing a downward trend during the last decade. But the single most quoted source, NASA, says exactly the opposite. From an article on The Register…

How can scientists who report measurements of the earth’s temperature within one one-hundredth of a degree be unable to concur if the temperature is going up or down over a ten year period? Something appears to be inconsistent with the NASA data - but what is it?

One clue we can see is that NASA has been reworking recent temperatures upwards and older temperatures downwards - which creates a greater slope and the appearance of warming.

[From Is the earth getting warmer, or cooler? | The Register]

The report suggests that NASA has been “correcting” historical temperature records using some method known only to them. These corrections don’t agree with anyone else’s historical records, and result in a more convincing upward slope in temperatures over the last century than anyone else’s data. Interestingly, the man in charge of the NASA data is Dr. James Hansen: science advisor to Al Gore, and a luminary in the global warming advocacy movement.

There are a ton of interesting links and data in the article. What is the truth? Well, as I’ve said before, I think humans have had a major negative impact on the world’s environment and climate, and it is critically important to start doing something about it. But I also think we barely understand how the climate actually works, and if we are being fed rejiggered data by various supposedly authoritative bodies then the job of trying to figure out the reality becomes increasingly impossible.

There is a lot of evidence of misdirection and outright lying on both sides of the global warming discussion: enough to make me doubt where the truth actually lies. There are obvious (to me, at least) political agendas here. Unfortunately, scientists are human just like the rest of us: subject to arrogance, hubris, political scheming, power hunger, greed, and all the rest. Usually, scientists are, as a whole, capable of self-regulating- the nature of their work demands that they question the common truth. But when funding, careers, and public opinion can be pulled, terminated, and manipulated, it makes it hard for scientists to remain honest and neutral.

According to Dr Hansen, the climate tipping point will arrive within my own lifetime. By 2016, we will be past the point of no return. Nothing we do after that will save us: if we haven’t already radically reduced our CO2 footprint, it will all be over. I hope Dr. Hansen is wrong, I fear he is right: regardless, we have to make major changes to the way we live, or pay the price. Just how radical do those changes have to be? Are we really the singular cause of the problem, or are there other factors at work? What worries me here is that the facts are being manipulated, possibly by both sides of the debate, and perhaps by people and organizations we should have absolute trust in.

Internet will be full by 2010- or so says AT&T doofus

Posted by Kelly Adams on 20th April 2008

According to Jim Cicconi, “Vice president of legislative affairs” at AT&T, the whole Internet will be completely full by 2010. If you believe Jim, 20 typical households in 2010 will generate more traffic than the entire Internet today.

Sorry to have to break this to you, Jim, but you are either a complete ignoramus or you assume everyone you are talking to is. There is no credible evidence that anything this VP is saying has any truth to it whatsoever. Doing some simple math should make this incredibly clear: the aggregate bandwidth of the main U.S internet backbone is measured in terabits per second. There is no conceivable way that 20 U.S. households could consume even a noticeable fraction of that bandwidth. Even countries like Japan where “low bitrate” home connectivity means 20 Mbps have no problems managing the capacity of their Internet backbone. And there is absolutely no likelihood that anything approaching 20 Mbps to the home will become “standard” in the U.S. within the next decade, let alone the next three years.

So, why would this supposed senior executive, whose title implies to me that his primary skill is lobbying government officials to do AT&T’s bidding, say such incredibly inaccurate things? Simple- money.

AT&T and the other major communications network providers have built backbone networks that are pretty robust: home users aren’t going to impact that. No, the real problem is at the edge of the network. The mythical “last mile”, from the service provider’s backbone to the local concentrator and finally to your home. For the past two decades, network service providers have been massively over-committing the bandwidth at the edge of their network to home users: that is, they are selling the same bandwidth promise over and over and over again. The 4 Mbps you pay for, as an example, might share a common 10 Mbps link with 100 other people in your neighborhood who are also paying for 4 Mbps. This works out okay when no one is actually using what they paid for. But if more than two or three of those 100 people start using the network bandwidth they think they deserve, then the service providers have a problem.

Let me repeat my example for clarity: 100 people are paying for 4 Mbps of bandwidth. To increase profits, the service providers are pushing all 100 of those people through a single 10 Mbps link. That 10 Mbps link is overcommitted by approximately 40 times: if it were properly sized, it would be 400 Mbps to accommodate all of the capacity that the service provider had actually sold. Note that the websites and other Internet services home users connect to are *also* paying for connectivity to the Internet. Google, Apple, and Youtube spend millions of dollars a month of bandwidth each- but they get the bandwidth that they pay for, and that is written into their contracts. Not so for the home users.

To correct the massive overcommitment problem at the “last mile” to home users would cost tens of billions of dollars. The Telcos could afford the necessary upgrades, but that would cut into their profit margins for many quarters. For years they have been selling a pig in a poke: raking in profits based on the fact that they are selling something they can not conceivably deliver on the infrastructure they have deployed. Now more and more people are actually starting to use some significant portion (I.E.: more than 10%) of the bandwidth they have already paid for. And this causes a problem for the service provider’s business model.

Naturally, the service providers would like to make more profit, not less. So what they want to do is “shape” or throttle traffic, and charge both end users (I.E.: you) and service providers (I.E.: Google, Microsoft, Apple) extra to make sure you actually get the bandwidth you are already paying for. It is much, much cheaper to lobby the government to make sure they have the ability to get paid at least three times for every bit that gets pushed through their networks than it would be to actually upgrade the network appropriately.

What is at risk here isn’t the Internet. What is really at risk is the defective business model deployed by the major service providers themselves. They can’t see a way to keep on selling bandwidth the way they have (I.E.: massively overcommitting bandwidth to the home) without reducing their profits, so they are looking for legislative support to grant them a new way to charge extra for what people have already paid for.

When you hear about Network Neutrality, and you read about the big service providers like AT&T being against the concept… this is what it is all about. AT&T and their friends want the ability to charge you again for the bandwidth you have already paid for, all because they sold you a lie to begin with and can’t figure out now how to deliver what they promised without cutting into their profit margin. And since their initial lobbying efforts against Network Neutrality weren’t very well received, they are now starting to preach that the Internet is facing imminent collapse unless they are granted what they want.

Whenever I read about these tactics on the part of the big network providers, I can’t help but imagine a big, greasy mafia guy threatening some poor family in their home… “dats a nice movie you iz downloadin’ dere. Would be a shame if sumthin were to happin to dat movie, ya know what I mean? Bits could get lost, mabbe the connection drop: things like dat, they just happen, ya know? I cud look out fer dat, ya know, keep yer bandwidth safe. Fer a fee…”

Iron Man trailer to be adapted into full length film?!

Posted by Kelly Adams on 16th April 2008

I’m shocked and disappointed. Apparently, that Iron Man trailer I told you about some time ago is being made into a (are you sitting down?) a *movie*


Are they crazy? This is nuts- they’ll ruin it!
Sometimes The Onion really does manage to tickle my funnybone….
