More wireless data

Imec and Panasonic have developed a 40nm low-power low-cost CMOS device implementing the IEEE 802.11ad standard – which transports high bandwidth data over a short range. At 7Gbps over short distances it is faster than the 5Gbps provided by USB 3.0.

High bandwidth short range wireless technology will enable many new applications for fast connections that are also intrinsically more secure than wider reaching networks. However this low power version requires more development before it is ready for commercial applications.

Using your data

The inventor of the World Wide Web Tim Berners-Lee says that although data about us is held and used by others we should have automated access to it so that we can make more use of it. He thinks that this will spawn useful new services. Sir Tim says that standardised data forms are required to simplify use of the data by these new services.
Some entities may be reluctant to provide access to this data because their businesses are built on it or they gain commercial advantage through it. It is not just the new breed of IT companies like Facebook that hold this data. Government, supermarkets, leisure groups, hoteliers, travel providers and many others hold our data and access to it is not easy.
The UK Data Protection Act allows for data access, but does not mandate automated access. Inevitably we will need legal rights of automated access to our data as well as technical solutions to exploit it.

Quick SSD v HDD comparison

Capacity & price:
The OCZ Revodrive 3 x2 240GB SSD is less than 25% of the capacity of the Western Digital VelociRaptor 1TB HDD but costs about twice as much. So the SSD storage is roughly 8 times as expensive.

Read speed:
SSD 1520MB/s, HDD 200MB/s – SSD is roughly 7.6 times as fast.

Write speed:
SSD 1129MB/s, HDD 200MB/s – SSD is roughly 5.6 times as fast.

Semantic search improvements by Google

Google are improving their game. They know a good deal of information about us and many other entities we commonly deal with, and associations between entities. Therefore they can infer more useful search results from the usual thin stream of information we give in a search because the context of a search is much greater than what we type in. This should make for more accurate search results. However this could also tend to push the more interest results down the list, reducing the chance for serendipitous discoveries. Perhaps they can provide a serendipity slide control. Anyway, this also opens up a new frontier for SEO and dilutes a little the heavily abused priority attached to links. Good thing too.

Is cloud the right choice?

The risk of interrupted access to data can be measured in terms of the amount of computing hardware and software it must pass through. So if the only or main data store and processing is by internet services, the risk to access is much higher. The same can be said of data security. Indeed, by UK law some data must be held with specific constraints that naturally militate against the main principle of the cloud, which is to delegate IT management, reducing IT to a set of benefits and business level decisions. Nonetheless, cloud solutions do present opportunities to do things that were difficult or impossible before, especially in terms of scalability and volatility of resource requirements.
All this raises an important question: Are cloud services a sound choice if more proximate services are an option?
I think the cases where cloud services are the only option are few. I also don’t believe that a substantial cost reduction is possible because of purchasing large amounts of equipment, especially when the costs of running a large organisation are taken into consideration. Locating services in economies with lower costs definitely has price advantages, but at the cost of access time and risk to access and security. I have noticed that where worthwhile cost reductions have been claimed it is often at the expense of IT jobs. As a result either the cloud provider must be adding a similar number of people and hence costs which will eventually return in service prices, or the services offered cannot be as well matched to the specific needs of the business. That standardisation of IT and hence business processes reduces the opportunity for business differentiation.
In the end there is no generic answer to the question. Care must be taken to make the right decision.
