The new chip is 0.05 x 0.05 mm on either side, or small enough to exist as a powder or dust, and possibly even as a floating cloud. Each can store a 38-digit number, which means you could actually get quite a bit of information into a cloud

Consumer electronics
Stop buying this crap. Just stop it. You don’t need it. Wait a year until the reviews come out and the other suckers too addicted to having the very latest and greatest buy it, put up a review, and have moved on to something else. Stop buying broken products and then shrugging your shoulders when it doesn’t do what it is supposed to. Stop buying products that serve any other master than you. Use older stuff that works. Make it yourself. Only buy new stuff from companies that have proven themselves good servants of their customers in the past. Complaining online about this stuff helps, but really, just stop buying it.
You want to know the punchline? The average Joe that makes up the market is smarter than you saps. The market-at-large waits until a clear leader emerges, then takes a modest plunge. You may think you’re making up the “bleeding edge” of “gadget pimpatude” but you’re really just a loose confederation of marks the consumer electronics industry uses as free market research and easy money. “Give me the latest version,” you coo, hiking up your skirt another cm over your exposed wallet. “0.1 upgrades make me so hot.”
3D printing comes to Sears
$1800 computer-controlled Craftsman CNC machine that can “print” your 3D designs on wood and other materials, either from a direct PC hookup or a memory card.
Hidden Interfaces to “Ownerless” Networks
We contacted all major manufacturers of Wifi chipsets in the US (2000-04) and requested interface documentation. We had little success and found unsupportable rationales for secrecy. We contend that constellations of private part 15 equipment should be considered as an “ownerless” whole network where interfaces should be compelled using a procedure similar to Sec. 68.110.
how the unavailability of hw docs slows down mesh networking r&d (and how the FCC is used as a scapegoat for secrecy)
Metamaterial
A metamaterial allows special optic properties, such as exceeding the diffraction limit, building cloaking devices, etc
2012-12-10: Materials science really is the unsung hero of most of our prosperity.
A new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape. Rather than liquid metal, it is a hydrogel, a mesh of organic molecules with many small empty spaces that can absorb water like a sponge. It qualifies as a “metamaterial” with properties not found in nature and may be the first organic metamaterial with mechanical meta-properties.
2014-01-12: Analog computers
shining a light wave on one side of such a material would result in that wave profile’s derivative exiting the other side. Such analog computers would be much faster and energy efficient than DSPs.
2014-02-10: This is easily the most impressive nanotech demo I have ever seen.
Extremely strong yet ultra-light materials can be achieved by designing nano structured hollow lattices which promise superb thermomechanical properties at extremely low mass densities (lighter than aerogels)
2015-12-01: 1000x 3D imaging resolution
MIT researchers have shown that by exploiting the polarization of light — the physical phenomenon behind polarized sunglasses and most 3D movie systems — they can increase the resolution of conventional 3D imaging devices as much as 1000x. The technique could lead to high-quality 3D cameras built into phones, and perhaps to the ability to snap a photo of an object and then use a 3D printer to produce a replica. Further out, the work could also abet the development of driverless cars.
2021-02-07: Metalenz
Instead of using plastic and glass lens elements stacked over an image sensor, Metalenz’s design uses a single lens built on a glass wafer that is between 1×1 to 3×3 millimeter in size. Look very closely under a microscope and you’ll see nanostructures measuring one-thousandth the width of a human hair. Those nanostructures bend light rays in a way that corrects for many of the shortcomings of single-lens camera systems. The resulting image quality is just as sharp as what you’d get from a multilens system, and the nanostructures do the job of reducing or eliminating many of the image-degrading aberrations common to traditional cameras. And the design doesn’t just conserve space. A Metalenz camera can deliver more light back to the image sensor, allowing for brighter and sharper images than what you’d get with traditional lens elements.
2022-01-30: Not sure about “soon”, but
Imagine a camera that’s mounted on your car being able to identify black ice on the road, giving you a heads-up before you drive over it. Or a cell phone camera that can tell whether a lesion on your skin is possibly cancerous. Or the ability for Face ID to work even when you have a face mask on. These are all possibilities Metalenz is touting with its new PolarEyes polarization technology. Polarization imaging equipment has typically been bulky and expensive, but the PolarEyes system is compact and cost-effective enough to replace a smartphone camera.
2022-04-15: Nice overview of metamaterial capabilities and progress.
Metamaterials’ precise shape, geometry, size, orientation, and arrangements allow them to manipulate electromagnetic or mechanical waves, such as light or sound, by blocking, enhancing, and bending the waves. Their potential applications are multiples, including power transmission, energy harvesting, wireless charging, thermal management, and acoustic applications, Lidars, radars, superlenses for medical devices, AR displays. Electrical engineering, electromagnetics, classical optics, solid-state physics, microwave and antenna engineering, optoelectronics, material sciences, nanoscience, and semiconductor engineering are all involved in the metamaterial field’s advancement.
Metamaterials are impacting several industries: Infrastructure (Thermal management, Acoustic management – vibration and noise control, Seismic metamaterials), Power and Energy (Energy harvesting, Power transmission, Wireless charging), Electronics and Sensors (Lidars, Super lenses for medical applications, Programmable metamaterials, AR displays), Telecommunications (MmWave antennas, 3D radar, Holographic beamforming).
Since the first metamaterials product went to market in 2009, relatively few products became commercially available because the difficulty in designing metamaterials structures and their high manufacturing cost made them prohibitive for commercial applications. In the last few years, improvements in the software for design and simulation in additive manufacturing made the near-term scale adoption of metamaterials-based products possible. Sectors like automotive, telecommunication, and consumer electronics are ripe for disruption. Once metamaterials options reach the market, the conventional products will suffer and likely become obsolete. The metamaterials products don’t require high CapEx because they rely on conventional materials and manufacturing processes with innovative design. When considering a new investment opportunity or starting a company, keep in mind that companies such as Intellectual Ventures have aggressively acquired strategic patents and launched several spin-offs, including Kymeta, Pivotal Commware, and Echodyne. Intellectual property in this field is strategic for the survival of incumbents. Early patents are expected to expire between 2024-2028, and more companies will likely pop up in analogy to what happened in the 3D printing industry in 2005. Exciting times lie ahead to transform many industries with metamaterials products.

Reproducible Setups
this is the second time in less than 6 months that i have to migrate my work environment from one laptop to another. i bought a new T42, probably one of the best deals out there. the 7200 RPM and the 1400 x 1000 screen make all the difference. just for comparison, this packs the same screen real estate you get with the 17 inch powerbook into 15 inch, you get 7200 RPM instead of 5400 RPM, and it sets you back $1800 instead of $2700. no wonder apple is changing their hardware platform 😉
as always, moving is a huge pain. this time, i have to deal with my 3GB, 250K file eclipse workspace, with countless settings across applications, logins etc. fortunately, there is freesshd for windows, which makes scp an option and allows me to sidestep all the SMB nonsense.
new baby
the thinkpad x31 is slightly bigger than the old vaio i had in 1998-1999
it’s still very small and versatile though 🙂 and who needs a cdrom these days, i certainly don’t. give me wifi every day.
