How you might get food delivered through Pinterest

When you search for a recipe on Pinterest, the results soon might include a way to have the ingredients delivered to your door within 45 minutes.That’s not a function built into Pinterest yet, but it could arrive in the future as the company grows its new platform for third-party developers. That platform, announced last month, is designed to let outside developers incorporate their own apps and services into Pinterest’s site to expand how the site can be used.Content on Pinterest is organized into visual bookmarks, or “pins.” Outside partners, such as advertisers, already work with Pinterest to incorporate content like images and product information into their pins. The new developer platform would allow select third parties to integrate services and do it on their own, without Pinterest’s help.To read this article in full or to leave a comment, please click here

Understanding TSA Math

At the end of every year, the TSA blogs about the weapons and explosives it prevented from getting on board airplanes. They are trying to brag about all the dangers they've stopped. But the opposite is true, when you do the math, you realize that they are stopping no dangers at all. The TSA stops less than half the bombs that get on board airplanes -- yet airplanes are not falling out of the sky due to the bombs that do get on board. Thus, mathematically, bombs aren't a danger. It therefore doesn't matter if the TSA stops bombs or not.

We know the TSA stops less than 50% of bad stuff from various sources. The first is the government's own tests, such as that described in a recent story where the TSA failed a shockingly 95% of the time.

Another is a statistic reported by the TSA where the number of firearms they stop every year is rapidly increasing. This does not match any other trend in society, such as the number of people carrying firearms. The only reason for such rapid growth is that the TSA gets better every year at detection. That means, historically, the TSA is Continue reading

PHY Basics: How OFDM Subcarriers Work

Have you ever wondered just "how" OFDM subcarriers are able to be spaced so tightly together without any guard band in-between? Most Wi-Fi textbooks will simply state that the spacing of the subcarriers allows the harmonics to overlap, thus canceling out any interference.

OFDM subcarrier spacing creates "nulls" canceling out inter-carrier interference (ICI) without the need for guard bands or expensive bandpass filters

OFDM subcarrier spacing creates "nulls" canceling out inter-carrier interference (ICI) without the need for guard bands or expensive bandpass filters

OFDM divides a given channel into many narrower subcarriers. The spacing is such that the subcarriers are orthogonal, so they won’t interfere with one another despite the lack of guard bands between them. This comes about by having the subcarrier spacing equal to the reciprocal of symbol time. All subcarriers have a complete number of sine wave cycles that upon demodulation will sum to zero. 

This tells us that the spacing of the subcarriers is directly related to the useful symbol time (more specifically, the amount of time the transmitter spends performing IFFT). Because of this relationship, the resulting sinc frequency response curves from each subcarrier create signal nulls in the adjacent subcarrier frequencies thus preventing inter-carrier interference (ICI). OFDM is a form of frequency division multiplexing (FDD), which typically requires guard bands between carriers and specialized hardware Continue reading

Pure says users can upgrade the same all-flash array for a decade

Enterprise storage is a long-term bet. Pure Storage, a growing maker of all-flash arrays, is reshuffling the deck on that gamble in a way that might save IT departments time and money.Pure’s plan is to let customers keep the same system for a decade, upgrading various components as improved versions come out but never having to migrate the data from an older array to a new one. For some organizations, this could eliminate an expensive and time-consuming effort every few years.The elements of the new approach have been coming together for a while. But the company formally introduced the strategy and gave it a name—Evergreen Storage—as it unveiled its fourth-generation product on Monday. Evergreen Storage applies to all generations of Pure hardware already shipped as well as versions yet to come.To read this article in full or to leave a comment, please click here

Nokia wants to build data centers for mobile operators

Nokia wants to help mobile network operators launch new services and cut their costs with a new range of servers, switches and storage they can use to virtualize their networks.Enterprises have already adopted virtualization and cloud-based IT infrastructures, and now telecommunications operators are looking at doing the same thing. Meanwhile equipment vendors like Nokia are increasingly offering operators the hardware and software to provide telephony, messaging and mobile broadband as virtualized services.Telecommunications operators instigated the move away from dedicated, proprietary equipment to virtualized hardware. A group including AT&T, Verizon, China Mobile, Orange and Deutsche Telekom proposed a concept called NFV (Network Functions Virtualization), which is now being standardized by the European Telecommunications Standards Institute.To read this article in full or to leave a comment, please click here
