A Router So Complete, and Vexing

Even before someone coined the term “mashup,” mashups were popular in the technology world. Some are made in heaven, and are now standard pairings: clock+radio, refrigerator+freezer, cellphone+camera.

Readers' Comments

Readers shared their thoughts on this article.

Others are still on the early-adopter fringe: TV+Internet, camera+Internet, fridge+Internet.

This month, D-Link, the networking equipment company, will offer a mashup that nobody’s ever tried before: wireless router + home backup hard drive + digital picture frame. That, in a nutshell, is the D-Link DIR-685 ($300 list price).

The 685’s heart is in the right place. Its inventors have noticed that our high-tech homes are becoming cluttered with network-related gadgets and their associated cable creep. As long as people are going to buy all these different network gadgets, D-Link figures, why not combine them into one?

It’s the right idea. Unfortunately, D-Link is the wrong company to make it a reality.

First, the good news: once you get the 685 set up, it works very well indeed. It broadcasts your Internet connection wirelessly — a fast, strong Wi-Fi signal (802.11n). This single router turned my entire house into a Wi-Fi hot spot, thanks to its ability to blast through floors and walls. I was even getting three bars of signal (out of a possible four) all the way upstairs.

Every conceivable home router feature is on this machine’s configuration screens: port forwarding, Application Rules, individual Web site blocking, a sophisticated firewall, UPnP, Multicast Streams, Wake on LAN, users and groups, network access lists, scheduled lockouts, logs, security formats like WPA and WEP, remote management and much, much more. (And no, I’m not going to define those. If you’re among the geeks D-Link is apparently courting with this router, you know perfectly well what those things are.)

But you can get a much less expensive router with those features. The 685’s selling point is that it has some unique tricks up its sleeve.

One of them is a tiny (3.2 inch) color screen. It’s useful for inspecting the router’s settings, but it can also display dozens of Internet information widgets: weather, New York Times headlines sports scores, stocks, posts and — delightfully — photos from your Flickr accounts. It’s as if your router is now a Chumby, if you remember that desktop gadget.

(Too bad you can’t make the screen show you exactly what other people in the house or office are downloading or reading online. Now that would be an interesting feature.)

The 685’s case is so attractive (its antennas are concealed inside), and its widget feature is so cool that you might be tempted to set the thing on your desk and glance at its parade of Internet info-bits throughout the day. Unfortunately, nobody will do that; this thing has a really, really loud fan. If you’re close enough to the router to see your photos and widgets, you’re also close enough to be driven mad by its jet-engine whirring. Bedroom placement is out of the question.

The 685 also has a slot on the side for a hard drive, which is not included. That’s O.K.; that way, you can buy your own hard drive online, in the capacity you desire. (Shop for a “2.5-inch SATA” hard drive.) Once you click it into place, the router’s screen offers you the chance to format the hard drive, and you’re off and running.

Why would you want a hard drive in your Wi-Fi base station? Because now it’s a NAS drive (network-attached storage), which is geek-speak for “a hard drive that every computer in the house can access at once, wirelessly.”

For example, the whole family can use it as a backup hard drive. You can use it as a central storage repository for files that everybody needs — including, intriguingly, your whole family’s iTunes music collection. That’s right: put your iTunes folder on this drive, and now all computers can play whatever music is in it. The router’s name shows up at the left side of the iTunes window as if it’s an iPod, which is very cool.

You can even teach the 685 to download BitTorrent files in your absence. That’s right, software pirates, you can have it download huge TV and movie files even while you and your laptop are out of the house. You have to know the Web address of the file you want, and you have to paste that into the router’s extremely technical configuration pages in your Web browser. But once you do that, you can go away, confident that the downloaded files will be on the D-Link’s hard drive when you return.

The cherry on top is a feature called SharePort. It lets you connect a U.S.B. scanner, hard drive or printer — and once you do, any Mac or PC on the wireless network can use it.

The hottest PC technology for 2009

As one year draws to a close, it's only natural that we all want to know what new technologies are in store for us in 2009.
How many cores will your CPU have? How fast will they be? What will be powering PC graphics, and what type of memory will be the next must-have?
The problem is that top technology firms are already beavering away on products and kit that will supersede next year's star buys. So we set ourselves another task – to discover what's over the horizon.
Is next year's kit part of a bigger trend or a gathering revolution in technology? Read on to explore the PC's near and distant futures

Intel processors

The most hyped and heralded Intel technology for 2009 is the Core i7 processor, which was formerly codenamed Nehalem. Initial product launches will be aimed at high-performance servers; desktop and laptop versions will appear in the second half of 2009. From information provided at the Intel Developer Forum in August and the results we've seen in our lab tests, we can confidently say that Core i7 is the biggest architectural advance Intel has made since the Pentium 4 launched in 2000.
The architecture is scalable from two to eight cores and offers HyperThreading technology – the same system used in some Pentium and Xeon processors – to permit two threads per core. Energy efficiency is high on the list of benefits too. Rafts of architectural features provide increased performance per core at the same clockspeed (so more performance per Watt), and an innovative 'Turbo' mode works hand-in-hand with an improved sleep facility.
Unused cores can be put to sleep, as could those in Core 2; but whereas Core 2 processor cores still used some power in sleep mode, the unused cores in Core i7 will consume virtually no power. And there's more; to provide additional performance for applications that are not multithreaded and hence not able to take advantage of multiple cores, the Core i7 will boost the clock frequency of the remaining core while still keeping the chip within its design power consumption.
Intel isn't saying exactly how much of a boost the remaining core will get, but there are suggestions that it will be from 3.2GHz (the highest launch speed) to 3.4GHz or even 3.6GHz.
The introduction of Core i7 is an example of – in Intel speak – a 'tock'. Intel's so-called 'tick tock' model involves introducing a new generation of silicon technology and a new processor architecture in alternating years. This means that 2009 will be a 'tick' year and, in particular, it should be the year that Intel introduces its 32nm process. Intel was not willing to comment on whether the new process technology will permit an increase in clockspeed, even if only in Turbo mode.

AMD processors

AMD was not as forthcoming on its plans, initially only telling us that its main focus for 2009 will be on the 45nm technology transition. It's pertinent to note that AMD are a whole generation behind Intel. Despite this initial reticence to talk about futures, Senior Product Manager Ian McNaughton did respond to a couple of questions. His main revelation was that six-core processors will join triple- and quad-core products in the Phenom processor line up during 2009.
Having seen that Intel is looking to boost clockspeeds when some of the i7's cores are idle, we tried to get the lowdown on whether AMD has any plans in this area – or whether the megahertz wars are truly over. Ian's response was not surprising given that AMD hasn't quoted the clockspeed in its part numbers for many years.

How to upgrade your laptop components

One of the wonders of the modern computer is its modular nature. And at times like this, when money may be tight, it's more tempting than ever to open up your PC's case and effect an easy upgrade instead of spending much, much more on a new system.
Some extra memory will improve your machine's ability to multitask, while a faster hard drive will enhance file writing. The proposition changes a little if your system is a laptop – but it needn't. Your notebook computer is in many ways just as easy to upgrade as your desktop. All it takes is a little more preparation.
Here we pass on the tips that we've learned from cracking open the shells of numerous notebook computers, from picking the best tools for the job to finding the right guide to help you do things properly.
Upgrading a laptop is very different to upgrading a desktop PC. Whip off the case of a standard tower and the motherboard is instantly exposed, with the slots, CPU and drive all easily accessible. In a notebook, the components are crammed into a much smaller space and are often layered on top of each other. Some forward-thinking manufacturers design their machines to provide easy access to the parts that are most likely to be upgraded.
On the back of a Toshiba Satellite Pro, for example, you'll find cutaway hatches for accessing the RAM, Wi-Fi card slots and the hard disk. Other machines hide their wares, requiring you to remove the keyboard and sometimes even other components before you can get at a part to upgrade it.
Why bother upgrading?
There are three good reasons for upgrading your laptop. The first, and most important, is cost. You can easily eke out the effective life of a laptop with a cheap upgrade or two.
Another reason for cracking open your laptop case is to make repairs. Notebooks are prone to drops and knocks; components can come loose and elements with moving parts are easily broken. You'll save yourself a bundle in labour costs if you're confident enough to replace an ailing optical drive or sticky keyboard.
Our third reason for carrying out some DIY upgrades is to make your notebook a better, stronger and faster device. Adding the latest Wi-Fi card or a solid state drive to speed up data access could transform your notebook from a mobile standby into an effective desktop replacement.

Arab environment 'under threat'

arabdesert_flickr_OliverN5.jpg

[CAIRO] The fragility of the environment of the Arab region — which suffers from widespread desertification and water scarcity — will be exacerbated by climate change unless governments plan for sustainable development and invest in environmental scientific research, says a report.

The report, 'Arab Environment: Future Challenges', published by the regional nongovernmental organisation the Arab Forum for Environment and Development (AFED), was launched last week (3 March) in Beirut, Lebanon. It assesses the current and future state of a range of environmental issues in the region, from water scarcity to urbanisation.

The region faces a temperature increase of 2–5.5 degrees Celsius by the end of the century, coupled with decreased precipitation of up to 20 per cent and sea level rise that could wipe out areas of agricultural land and displace millions.

The report calls for mitigation and adaptation strategies to be integrated into national and regional development strategies and for more funding and facilities for climate change research.

Most Arab countries will face severe water scarcity by 2025. In 2001, average available water supplies per person in the Arab region were 977 cubic metres —below the UN definition of water scarcity, according to the report. Projections put this figure lower still, at 460 cubic metres by 2023.

Improved management is essential to ensure better water use and improved allocation of resources between agriculture, industry and domestic use, the report says.

Land degradation has also destroyed 34 per cent of irrigated agricultural land in the region and the report says that the Arab region loses US$5 billion of agricultural revenue per year because of desertification.

Long-term environmental management strategies; powerful and effective environmental agencies; clear political and legislative mandates; and environmental research, education and media input are required, the report concludes.

"Exchange of experiences, success stories and dissemination of the best management practices are among the effective tools to handle this problem,"Radwan Al-Weshah, regional advisor for water science in Arab states at UNESCO Regional Office in Cairo, Egypt, told SciDev.Net.

Wael Hmaidan, executive director of Lebanon-based environmental group IndyAct added that unless environmental issues are prioritised on all political levels, economic costs of environmental degradation will increase exponentially with climate change.

Qatar puts its science articles online

Qatar is sharing its scientific research in an online database to promote international and regional scientific collaboration.

The Qatar National Research Fund (QNRF) launched the open access database last month (5 February). It is a repository of 37 years — from 1970 to 2007 — of Qatari science and technology (S&T) research in a range of disciplines and also includes abstracts of Master's and PhD theses.

About 4,600 records of professional, academic, undergraduate and commercial research conducted partly or wholly in Qatar have been entered into the database. Each publication includes at least one author who is affiliated to a university or research organisation in Qatar.

The database was compiled by the QNRF in collaboration with the Planning Council and Qatar University through an online survey obtaining information about research papers and by direct contact with academic and government organisations, and research centres.

It will be updated by the QNRF in 2010 to include Qatari research output during 2008 and 2009.

Abdul Sattar Al-Taie, director of the QNRF and a member of the Qatar Foundation for Education, Science and Community Development, told SciDev.Net that the database will promote awareness of Qatari research and be used by researchers for future scientific work.

Qatar was highlighted as an example of technology-driven excellence last year

"The impact of this valuable national S&T database must be increased by strengthening the poor Internet infrastructure within Arab universities," Magdi Tawfik Abdelhamid, a researcher at Cairo's National Research Centre, told SciDev.Net.

He adds that the database should be linked with other S&T databases and information centres to "lead to the establishment of an open access Arab S&T gateway that will be an excellent tool for facilitating knowledge transfer as well as promoting Arab scientific cooperation".
