Apple iPad

January 27th, 2010

Update: Well, the reviews seem a bit mixed from the tech crowd even as the TV news stories are about the best thing Apple could have hoped for – breathless anchors telling us how much they want an iPad.

Wall Street Journal has a good summary of the early buzz. My take so far is that these are the key features in play:

“low price” “giant iPhone” “many applications” “high quality” “no still or video camera” “potential typing challenges”

This morning Apple launched what is almost certain to become the new tablet computing standard, the Apple iPad. Reviews will be coming in at a lightning pace today and we’ll try to summarize them later, but in the meantime here’s a great “Everything you need to know about the iPad” piece from the Gizmodo people.

Computers at CES?

January 15th, 2010



ASUS at CES

Originally uploaded by JoeDuck

There are more different types, sizes, and brands of computers at CES than you can shake a stick at, though Apple is always conspicuously absent. In fact the Apple Tablet somewhat overshadowed much of the innovations of the Las Vegas show because clearly the Apple Tablet is going to be the “one to beat”, especially given the lack of any clearly “superb” tablet offering at CES.

Although I have not done enough research to generalize much about the best new PCs I think it’s clear that the mainsteam trend is towards smaller laptops and netbooks with robust features. Costs are going down – features that would have been unheard of at any cost 5 years ago are now standard on even a modest PC. Battery life is impressive and getting better – one of the ASUS PCs shown here had a battery that lasted something like 10 hours.

ASUS also has a new interesting line of *very large* laptops with high quality speakers built into the sides of the chassis to the left and right of the screen. Although heavy, these will offer huge power and a “desktop” feel for your mobile computing. Still, I think weight is the key factor driving down PC size and predict it’ll be the netbooks that dominate the market for the next few years.

Neuroscience Expert Dr. Henry Markram on the IBM “Cat Brain” Simulation: “IBM’s claim is a HOAX”

November 25th, 2009

Editors Note:   We’re hoping for more information from Dr. Modha who is also welcome to a Guest post here at Technology Report.

——   Guest Post by Dr. Henry Markram of the Blue Brain Project —-

IBM’s claim is a HOAX.

This is a mega public relations stunt – a clear case of scientific deception of the public. These simulations do not even come close to the complexity of an ant, let alone that of a cat. IBM allows Mohda to mislead the public into believing that they have simulated a brain with the complexity of a cat – sheer nonsense.

Here are the scientific reasons why this is a hoax and misleading PR stunt:

How complex is their model?
They claim to have simulated over a billion neurons interacting. Their so called “neurons” are the tiniest of points you can imagine, a microscopic dot. Over 98% of the volume of a neuron is branches (like a tree). They just cut off all the branches and roots and took a point in the middle of the trunk to represent a entire neuron. In real life, each segment of the branches of a neuron contains dozens of ion channels that powerfully controls the information processing in a neuron. They have none of that. Neurons contain 10’s of thousands of proteins that form a network with 10’s of millions of interactions. These interactions are incredibly complex and will require solving millions of differential equations. They have none of that. Neurons contain around 20′000 genes that produce products called mRNA, which builds the proteins. The way neurons build proteins and transport them to all the corners of the neuron where they are needed is an even more complex process which also controls what a neuron is, its memories and how it will process information. They have none of that. They use an alpha function (up fast down slow) to simulate a synaptic event. This is a completely inaccurate representation of a synapse. There are at least 6 types of synapses that are highly non-linear in their transmission (i.e. that transform inputs and not only transmit inputs). In fact you would need a 10’s of thousands of differential equations to simulate one synapse. Synapses are also extremely complex molecular machines that would themselves require thousands of differential equations to simulate just one. They simulated none of this. There are complex differential equations that must be solved to simulate the ionic flow in the branches, to simulate the ion channels biophysics, the protein-protein interactions, as well as the complete biochemical and genetic machinery as well as the synaptic transmission between neurons. 100’s of thousands of more differential equations. They have none of this. Then there are glia – 10 times more than neurons..And the blood supply…and more and more. These “points” they simulated and the synapses that they use for communication are literally millions of times simpler than a real cat brain. So they have not even simulated a cat’s brain at more than one millionth of it’s complexity.

Is it nonetheless the biggest point neuron simulation ever run?
No. These people simulated 1 billion points interacting. They used a formulation to model the summing up and threshold spiking of the “points” called the Izhikevik Formulation (an extremely simple equation). Eugene Izhikevik himself already in 2005 ran a simulation with 100 billion such points interacting just for the fun of it: (over 60 times larger than Modha’s simulation). This simulation ran on a cluster of desktop PCs and which every graduate student can run This is no technical achievement and certainly not even a record number of point neurons. That model exhibited oscillations, but that always happens so even simulating 100 Billion such points interacting is light years away from a brain.
see: http://www.izhikevich.org/human_brain_simulation/Blue_Brain.htm#Simulation%20of%20Large-Scale%20Brain%20Models

Is the simulator they built a big step?
Not even close. There are numerous proprietary and peer-reviewed neurosimulators (e.g., NCS, pNEURON, SPLIT, NEST) out there that can handle very large parallel models that are essentially only bound by the available memory. The bigger the machine you have available, the more neurons you can simulate. All these simulators apply optimizations for the particular platform in order to make optimal use of the available hardware. Without any comparison to existing simulators, their publication is a non-peer reviewed claim.

Did they learn anything about the brain?
They got very excited because they saw oscillations. Oscillations are an obligatory artifact that one always gets when many points interact. These findings that they claim on the neuroscience side may excite engineers, but not neuroscientists.

Why did they get the Gordon Bell Prize?
They submitted a non-peer reviewed paper to the Gordon Bell Committee and were awarded the prize almost instantly after they made their press release. They seem to have been very successful in influencing the committee with their claim, which technically is not peer-reviewed by the respective community and is neuroscientifically outrageous.

But is there any innovation here?
The only innovation here is that IBM has built a large supercomputer – which is irrelevant to the press release.

Why did IBM let Mohda make such a deceptive claim to the public?
I don’t know. Perhaps this is a publicity stunt to promote their supercompter. The supercomputer industry is suffering from the financial crisis and they probably are desperate to boost their sales. It is so disappointing to see this truly great company allow the deception of the public on such a grand scale.

But have you not said you can simulate the Human brain in 10 years?
I am a biologist and neuroscientist that has studied the brain for 30 years.  I know how complex it is. I believe that with the right resources and the right strategy it is possible. We have so far only simulated a small part of the brain at the cellular level of a rodent and I have always been clear about that.

Would other neuroscientists agree with you?
There is no neuroscientist on earth that would agree that they came even close to simulating the cat’s brain – or any brain.

But did Mohda not collaborate with neuroscientists?
I would be very surprised if any neuroscientists that he may have had in his DARPA consortium realized he was going to make such an outrages claim. I can’t imagine that that the San Fransisco neuroscientists knew he was going to make such a stupid claim. Modha himself is a software engineer with no knowledge of the brain.

But did you not collaborate with IBM?
I was collaborating with IBM on the Blue Brain Project at the very beginning because they had the best available technology to faithfully allow us to integrate the diversity and complexity found in brain tissue into a model. This for me is a major endeavor to advance our insights into the brain and drug development. Two years ago, when the same Dharmendra Mhoda claimed the “mouse-scale simulations”, I cut all neuroscience collaboration with IBM because this is an unethical claim and it deceives the public.

What IBM allowed Modha to do here is not only wrong, but outrageous. They deceived millions of people.

iLounge to feature Apple Products at CES in large new exhibit Space

November 12th, 2009

Even as reports come in that CES 2010 won’t be as big as CES 2009 or CES 2008, an exception to the size reductions is coming from an unlikely direction.   The Apple iPod .   The CES  iLounge, sponsored by the website iLounge, will feature a large number of Apple products and accessories.   The plans are to exhibit in a very big way at this year’s CES.

According to a report much earlier this year by Mark Harris at TechRadar, Apple is not only abandoning MacWorld  Expo but they are allocating massive space to showcase products at CES 2010 in Las Vegas in January.   The iLounge exhibit at CES  had 18,000 square feet as of the article’s publication in January.

“Leading Apple developers and retailers are excited to have such an outstanding stage at the 2010 International CES,” said Jeremy Horwitz, Editor-in-Chief of iLounge.
“Whether they’re showing off iPod accessories, iPhone applications, or the latest and coolest new Mac products, they know that they’ll find the world’s largest audience at this great new pavilion.”
Harris quotes Jeremy Horowitz, the man in charge of the iLounge exhibit:
“Leading Apple developers and retailers are excited to have such an outstanding stage at the 2010 International CES,”
“Whether they’re showing off iPod accessories, iPhone applications, or the latest and coolest new Mac products, they know that they’ll find the world’s largest audience at this great new pavilion.”

Historically Apple has had a very limited presence at CES events, tending to make a big splash at MacWorld instead.    It’s not clear why the big change this year and it seems odd for Apple to abandon one of their most prominent venues, but in the fast pace world of computing loyalties can change almost as fast as the technologies.

Tech Tip: Printing Problems from Browser Window

October 13th, 2009

Print troubleshooting is one of the most frustrating aspects of computing. Although printer quality and cost has become very reasonable, there’s nothing more frustrating than printer failure during a deadline for an important paper or letter.

Some good troubleshooting rules of thumb are as follows if you suddenly experience a dreaded printer FAIL:

1. If you seem to be able to print text documents but cannot print things appearing in the browser, note that some printer / browser combinations won’t allow printing from within the browser window.   For example to print a PDF file from some Lexmark printers you’ll want to download the PDF first, then open it up in Adobe and then print.    Otherwise the document may come out blank.

Still not printing?

Some printers have good diagnostics so use those first, but I find that the generic Windows help often sends me down a garden path of confusion so consider trying these ideas first:

1.  Reconnect cables and reboot both system and printer.

2.  Confirm your have the correct printer driver installed.  The driver is the small program that allows your printer to communicate with your computer.   Usually the name of your printer plus “driver” at Google will quickly take you to a driver installation routine for most major printers.

3.  Confirm you have ink in the cartridge (for ink jet printers).   The simplest way to do this is often to install a new cartridge.   If it works then you are good to go, but if it fails then ink was probably NOT your problem before.

No Touch Computing via 3D Sensors

July 4th, 2009

The San Jose Mercury News has a summary today of the advent of “no touch” computing that will be coming fairly soon thanks to three dimensional sensors that represent the world to the machine in a much richer fashion than simple flat, 2 dimensional models.     3D sensors will allow people to interact with many devices in a much more natural way – for example via simply looking at a screen and moving your hands you could have dramatic control over a gaming environment.

The Mercury News seems to be suggesting that useful applications are about 5 years out but I’d guess we’ll have robust no touch devices within 3 years and high quality direct brain control within a decade.    Braingate is already using brain control and  Emotiv has developed a commercial version brain control device that uses theta waves that are read froma sensory “cap” with about 16 sensors.      The Emotiv headset will be available to consumers this year.

10″ Laptop Reviews from Laptop Magazine

March 4th, 2009

Laptop Magazine looked at several of the new 10″ Netbook computers and has a nice write up of models from ASUS, Aspire, HP, Lenovo, MSI, and Samsung.

The ASUS and Aspire appear to be their favorites when all factors are considered but if you are in the market for a netbook you’ll want to read these and other reviews.

Happily for consumers if not for the industry at large, price in this category does not appear to correlate all that well with features and quality.

India Dept of Education to debut $20 Laptop on February 3rd NOT

January 30th, 2009

UPDATE:  Reports, pictures, and details are still murky but this appears to be a case of overhyped nonsense where the device is simply a flash drive system without monitor or keyboard:  http://education.zdnet.com/?p=2131

The Times of India and others are now reporting that a team of students and the Government of India have developed a low cost laptop that is expected to be put into widespread use throughout India very soon. The initial cost is reported to be $20 with a mass production cost expected to be $10.

Yes, you heard that right – ten bucks for a computer.

Although the specs on these machines will obviously be marginal, it is not longer important for most users to have a robust machine – rather cloud storage and applications and internet-as-network computing has become dominant even for many high end computer users.

As admirable as the One Laptop Per Child project has been to this process it appears the India machines may wreck the One Laptop train. Although it’s not clear yet if the India systems will be self powered and have mesh networking capabilities as the One Laptops do, I think the key brilliancy of Negroponte was to create machines that were accessible to a dramatically greater number of people than have had access in the past to advanced technologies. The India project combined with the dramatic innovations in smartphones and cellular connectivity combined with Intel’s falling out with One Laptop last year may obsolete the One Laptop project in its current form, though Negroponte can certainly be proud to have ushered in an era of “extremely low cost” computing.

Simcraft Racing Simulator

January 27th, 2009

John will have more later on this topic as he had a chance to test one of the world’s top racing simulators on display at CES by Simcraft but I wanted to get these pictures online .  We had a nice talk with Simcraft’s CEO about his plans for moving forward with this remarkable driving simulation tool.    Rather than the arcade market with its liability challenges he explained that one of  Simcraft’s major projects right now is a contract with the Department of Defense to use the simulators to train drivers for high speed runs when they must avoid IEDs in Iraq and other combat environments.

At $44,000 this is not accessible to most but with a remarkable cage suspension system that gives the driver 3 degrees of motion this really is likely to be the sim of choice for high end drivers who can pony up the cash.

Autoblog has more on this device – easily one of CES’ most impressive demos.

Ford CEO Alan Mulally at CES 2009

January 9th, 2009

Ford CEO Allan Mulally really impressed the crowd and reporters after his CES Keynote about Ford in vehicle connectivity and navigation innovations including systems to merge cellular connectivity with vehicle systems, a customizable dashboard, and a humanized communication interace called “Eva” which will allow the driver to request features and “talk” to the car.

Mulally was even more impressive after his talk when he answered questions from the tech crowd about Ford’s plans.   His enthusiasm or Ford and for technology in cars came through loud and clear.

I had a chance to ask him if he thought all this innovation would require money from the government as part of the auto industry bailout.   Ford is the only one of the three key US manufacturers that has not asked for money, and Mulally indicated they did not have plans to do so based on his assessments of the quality of Ford vehicles and how their new models are gaining acceptance even in Europe, especially Germany where Ford remains a popular brand name.

Although I wouldn’t bet on Ford not asking for a piece of the bailout pie eventually it is great to see a charismatic and technologically sophisticated fellow in charge of one of American’s most complex and valuable industries.  If Mullaly can’t pull Ford’s feet out of the fire, nobody can.
