The run up to this election has seen politicians promoting themselves more via Twitter feeds or Facebook groups than by kissing babies in the street. Clearly this shows us technophiles that today’s politicians are embracing the internet age – or does it? How much of this is just posturing? Did the empty seats in the House of Commons during the debate over the Digital Economy Act indicate that most MPs didn’t understand the Act’s impact, or that they just didn’t care? We decided to find out just what technology policies the different parties are offering, and interviewed the people who will be writing the tech manifesto for their parties if they win the election. There are some impressive claims being bandied about.

Parliament could have a very different look depending on your vote. (Parliamentary images reproduced with permission of Parliament)

Labour has been very vocal about its technology policies, not least its Digital Economy Act. This gives the government the right to block sites infringing copyright and ban downloaders from accessing the internet. They are also championing rolling out high-speed internet (well, 2Mbps) for everyone by 2012 and “superfast” 100Mbps broadband for 90 per cent of the population by 2017.

The Conservatives also want super-fast broadband for most of the country (which would be achieved by opening up BT’s infrastructure to other companies) and would reduce the corporation tax rate to encourage new technology businesses to set up in the UK.

The Liberal Democrats were vociferous in their opposition to the Digital Economy Act, and have plans to uphold net neutrality and overhaul copyright law. They too want high-speed broadband for all.

So just what are the most important tech policies for each party? Read on to see.

Conservative party

Jeremy Hunt, Shadow Secretary for Culture, Media and Sport told us: “Our key policy to promote the technology industry is to ensure that Britain has a modern, fast broadband infrastructure. We will deregulate the market and force BT to give access to its underground ducts and overhead telegraph poles to rival ISPs. This will allow ISPs to lay their own fibre at a lower cost, and a super-fast broadband-supporting fibre network will be established over much larger parts of the UK. Funding, where needed, would come from the Digital Switchover segment of the licence fee.”

What about the technological economy? “It’s vital that we encourage technology companies to set up in the UK. We’ll cut the headline rate of corporation tax to 25p or lower and the small companies’ rate to 20p, funded by reducing complex allowances.”

What in the Tories’ opinion have Labour got wrong? “An over reliance on massive-scale IT projects that have gone over budget and not been delivered on time. We will create a level playing field for open-source IT in government procurement and open up government IT contracts to [smaller companies] by breaking up large IT projects into smaller components.”

  • Super-fast broadband for all: Will deregulate the market and open up BT’s infrastructure to competitors. Paid for using the Digital Switchover section of the BBC licence fee.
  • Right to data: Statistics like street-by-street crime levels and power consumption of Government buildings to be put online.
  • Government to use open-source IT: Cost of large-scale IT projects would be reduced.
  • Cap government IT projects at £100m: Would let smaller IT companies help out.
  • Corporation tax reduction: Corporation tax rate reduced to 25p to attract tech companies.

Labour Party

Ben Bradshaw, Secretary of State for Culture, Media and Sport told us: “Labour wants Britain to be the world leader in the digital economy. We will create over 250,000 skilled jobs by 2020 and [become] the world leader in public service delivery. “We will ensure universal access to today’s broadband services at 2Mbps by 2012 – this will be delivered through upgrades to the existing networks and be supported with public funding including the underspend from the Digital Switchover Help scheme.”

“The Digital Economy Act is a key part of our active industrial strategy, helping us maintain and build on the digital economy. It ensures a competitive digital communications infrastructure [and] protects intellectual property. The Conservatives offered no practical solutions on [either] of these.”

Labour also has plans for a new technology institute: “The Institute of Web Science will be based in Britain and will work with government and business to realise the social and economic benefits of technological advances. It will assemble the best of the world’s scientists and researchers and be headed by Sir Tim Berners-Lee and the leading web science expert Professor Nigel Shadbolt.”

  • High-speed broadband: 2Mbps for all by 2012, paid for by a fixed telephone line levy of 50p a month. 100Mbps for 90 per cent of the country by 2017.
  • Government to use cloud computing: Would save £3.2billion annually
  • Digital Economy Act: Passed to provide a competitive digital communications infrastructure and protect intellectual property.
  • Home Access scheme: Reduce the number of non-internet users by 60 per cent by 2014.
  • Will increase scope of data.gov.uk: More previously private government data online.

Liberal Democrats

We asked Don Foster, Shadow Secretary of State for Culture, Media and Sport, which Lib Dem policies would interest a PC Plus reader. “Our policies on broadband roll-out and extending IT skills, and the work we’ve done on the Digital Economy Bill,” he answered. “The more people who have the skills and access to make use of technology, the more useful it becomes.

“We do not believe that the country’s broadband infrastructure can be left solely to market forces, which is why we advocate an outside-in use of public funds to begin delivering broadband from day one to rural areas. The market will deliver the infrastructure in urban areas.”

How would the Liberal Democrats attract tech companies to the UK? “We support the proposed tax break for the video games industry and we will also tackle the growing burden of red tape, which continues to cost businesses increasing amounts of time.”

What was the current Government’s biggest technology mistake? “Not prioritising the Digital Economy Bill in debate. The Bill was an opportunity to ensure that everyone is able to take advantage of the opportunities presented by the internet. The government’s unwillingness to give the Bill the time necessary for proper parliamentary scrutiny shows how low in their priorities it sat.”

  • Superfast broadband for all: Would use public funds to get broadband for everybody available straight away.
  • Support for tech business: Tax breaks for video-games companies and high-tech industries to encourage growth.
  • Overhaul copyright law: Update laws to reflect the technology of modern-day society.
  • Support for net neutrality: Would strongly oppose blocking of internet sites.

Small parties with big tech policies

What do the smaller parties contending for parliamentary seats offer to people passionate about the web, computers and technology? We spoke to five and found out. We also asked which of the policies that the big three parties were proposing could, in their opinion, damage the internet and technological development.
During our fact-finding mission we found much of interest. The Communist Party want to make tech-literacy part of the educational process as they feel computers are no longer a luxury, but a necessity. The Green party think broadband should be a fixed-rate service available to all. The Pirate Party UK are all about free speech – and not just on the internet. They want to ensure that personal privacy is a priority of government and industry. Plaid Cymru want an ultra-fast national broadband network and the SNP aren’t sure the Digital Economy Act goes far enough. The last word goes to the Monster Raving Loony Party, who, when contacted said: “What on earth are you talking about? Don’t be so serious.”

Ben Stevenson, National Secretary, Communist Party

www.communist-party.org.uk

“There are IT-related issues important to us. We oppose the Digital Economy Act, a sop to international big business. We recognise the need for a far-reaching and proactive approach to ensure all citizens can access all aspects of technology. It’s obvious that the speed of the technological revolution has made basic access and experience in using computers and the internet a necessity. Britain’s Broadband speed currently ranks 17th in the world, 23 times slower than Japan. We need an integrated communications strategy to bridge the gap. Education is essential to ensuring that tech-literacy is considered a vital part of modern life in Britain. IT needs to be given greater prominence in the National Curriculum and to be fully integrated into all its aspects.”

Andy Robinson, Party Leader, Pirate Party

www.pirateparty.org.uk

“We don’t just know what technology is, we know how it works and how it has affected our society. In the modern age, existing copyright and patent laws do not make sense. Our policy is to shorten the duration of copyright to five years, and to allow the sharing of copyrighted material provided that no profit comes of it.

The Digital Economy Act is a terrible piece of legislation. It legitimises corporate spying on individuals, forces ISPs to throttle or even ‘suspend’ connections based only on allegations of infringement and allows copyright holders to demand ISPs censor websites on the flimsiest of evidence. PPUK is unquestionably against these policies.”

Caroline Lucas, Party Leader, Green Party

www.greenparty.org.uk

“The Green Party believes that the development of computer communications has reached the point where BT should have an obligation to provide broadband-capable infrastructure to every household. Funding for marginal ‘uneconomic’ lines may come from a small levy on every access line. The principle of universal access at the same base price to the household should prevail.

Many of us believe that [the Digital Economy Bill] threatens to infringe fundamental human rights through the disconnection of internet accounts and the new ‘website blocking’ laws could result in new ways to suppress free speech and legitimate activity.”

Lowri Jackson, Research and Policy, Plaid Cymru

www.plaidcymru.org

“Connecting Wales to the world digitally will encourage innovation and job creation. We believe that new technology must be harnessed to provide Wales with a strong voice on the global stage and to ensure that there are no communication ‘not spots’. We call for research into the construction of a super-fast national broadband network. We also support compulsory network sharing between mobile phone and broadband operators. Westminster can learn a lot from the National Assembly with its transparent and democratic processes. We’re also concerned about the threat to our civil liberties implied by increased internet monitoring, and will campaign for freedom of the internet.”

Pete Wishart, Culture and Broadcasting, Scottish National Party

www.snp.org

“While the ambition to secure universal broadband access is to be welcomed, more must be done to protect those who are working in our creative economy. Our creative industries contribute significantly to the economy and are a key route to economic recovery, yet protection for artists and creators remains an afterthought. Writing letters to persistent downloaders and threatening slower internet speeds seems a feeble response to the loss of millions of pounds of income to artists and creators. What is needed is a mixture of effective technical measures and creative solutions, but above all the political will to tackle this problem.”


Question time with the Pirate Party

For some political parties technology is the reason they exist, and it seems to be paying off. The Swedish Pirate Party caused a stir last year when it gained two seats in the European Parliament. The UK’s Pirate Party has the same three core platforms: reform copyright and patent law, end ‘excessive’ surveillance of innocent people and ensure ‘real’ freedom of speech. But all these issues have possible downsides. We asked Pirate Party UK’s leader Andy Robinson if its policies would actually work in the real world.

PCP: Surely reforming copyright and patent law will damage British businesses?

Andy Robinson: There are always winners and losers when any law changes. Reforming copyright law will reduce the power of record industry ‘rights-holders’ to dictate what music we get to hear and what we don’t. It will also benefit lesser-known musicians who don’t want to sign away future royalties to get their music heard. Reforming patent laws to fix problems like the ring-fencing of huge areas by overly broad patents will increase competition and reduce red-tape. A better regime would encourage manufacturing and design investment, boosting the economy at no cost to taxpayers.

Did you know it’s illegal to sing Happy birthday in public without paying a fee? The Pirate Party would like to put an end to this.

PCP: Isn’t surveillance central to UK security?

AR: A certain degree of surveillance is necessary, but we urgently need to set sensible limits on it. Vehicles are being tracked: the police’s automatic number plate recognition camera network takes 14 million photos a day. We need rules that say how much is too much, before we sleepwalk into a surveillance state.

PCP: One man’s freedom of speech is another man’s persecution. How do you intend to protect the weaker and less vocal in society from the strongest and loudest?

AR: New media outlets empower many of the people who were previously disempowered to have their say. The best counter to persecution is not censorship, but education. Teaching people to get together and stand up for themselves is far better than short-term measures taken just so politicians can be seen to be doing something. That said, we support current equality legislation banning unfair discrimination and would not change this policy.

PCP: Where do you stand on more prosaic issues like internet speed?

AR: Consumers have been complaining about this for years. We plan a system where payment will be based on the speed the user actually gets, not the advertised headline speed. Of course, we’ll be unable to achieve any of our aims, prosaic or otherwise, without votes or the support of donations through our site (www.ppuk.it/donate).

All laptop users have something in common: we want our device’s batteries to last longer. Whether it’s for the daily commute or the flight home for Christmas, an extra 30 minutes of power means an extra 30 minutes of entertainment. If you’re running a Linux-based distribution on your netbook, there’s a lot you can do to squeeze every last negatively charged ion from your power source. Here we’re going to cover the best techniques that we’ve discovered. Don’t worry if you’re not a netbook user, as much of this information can be used on Linux laptops too. However, we’ve specifically tailored our advice for netbooks as these seldom include full-blown distros (and hence any easy way of compiling and installing new software). We’re going to focus on Intel’s Moblin and Canonical’s UNR (Ubuntu Netbook Remix), two of the most popular Linux distributions for netbooks, but there’s absolutely no reason why you can’t use a full-fat distribution on your device and make the same changes to its power management.

You deserve to be able to drag every last tiny drop of power out of your laptop’s battery. It’s only fair.

Netbook Linux is still in its infancy. This means that there’s still a great deal that can be done to make these devices more power efficient, and each release of distributions like Moblin or UNR gets better at it. But it also means that hardware compatibility and power saving is experimental for each distribution, especially when you’ve installed it yourself. Until netbook distributions are built for specific netbooks, though, there’s always something you can change in a generic installation to make it work better on your own machine. We’re not talking about massive improvements, but each incremental change may stretch your battery life by around five per cent. Even if just one or two of them work out, you’ll see some extra life from your machine. Like most things to do with Linux, it just takes a little trial and error.

The easy targets

Sometimes it’s the most predictable power saving options that can reap the biggest benefits. Wireless and Bluetooth are our first targets. Even when you’re not using these connections, the radio device tucked away within your machine is still expending energy, either keeping a connection in contention or looking for new networks and devices for you to connect to. Both Moblin and UNR allow you to disable these devices from the desktop, but these options won’t necessarily completely disable the radio. The best option is to use a hotkey combination that’s dedicated to your devices. These are usually labelled in blue across the laptop’s keyboard, and typically involve you having to press the [Fn] key in conjunction with a number. The number key will normally feature a somewhat ambiguous icon that you’ll need to decode in order to figure out which number is the correct one. If you’re lucky, you’ll also see an on-screen message updating you on any progress once you’ve pressed the key.

However, some netbooks don’t have function keys to disable the wireless or Bluetooth radios, and you can’t take any chances with the software disable function. Samsung’s popular NC10 is one example of a machine that doesn’t have a keypress option. In these cases, your only course of action is to change a setting in your netbook’s BIOS – a setting that will stay fixed until you restart your machine and manually undo the change.

It might sound obvious, but switching off your laptop’s internal radios can give a significant boost to battery life.

Like many desktop machines, you can normally enter your netbook’s BIOS by quickly pressing [F2], although like the hotkeys, this is dependent on your manufacturer (as is what you can and can’t turn off within the BIOS). With the NC10, for instance, you can switch your wireless devices to ‘Always Off’ from the Boot menu within the BIOS. While you’re there, you might also want to disable the ‘Internal LAN’ setting in the Advanced menu, as the Ethernet port can steal power even while not being used. You should also make sure that any power saving modes for your device are enabled.

Screen brightness

Dimming the screen is a great way of saving some power, but this can sometimes be problematic with certain netbooks running a Linux distribution. This is because the hotkey combination may not work from the desktop, and the software isn’t always capable of changing brightness either. The Linux kernel needs to have support for your specific device. If it does, the distribution you use also needs to use the correct version of the kernel and provide a means of changing the brightness. If this isn’t the case, you might still be able to adjust the brightness of your screen from the command line.

The trick is to use a special kind of file that accesses your display hardware. As with most devices, this can be found by typing ls /sys/class/backlight/. If you’ve not encountered the ‘/sys’ series of directories before, it contains dozens of folders and files that refer to each of the devices on your system. Rather than representing the files and folders on a storage device, this structure is a portal for configuring any plug-and-play hardware discovered on your system, and that includes devices like your netbook’s screen, CPU and drive.

To change values in the /sys tree, you will need to switch to the administrator’s account on your machine. Ubuntu users won’t be able to use sudo in the way they might be used to because the command to change values is really two commands, one piping output to another. The sudo privileges will only apply to the first and won’t stretch to allow you to change the parameter in the second. You can get around this by launching a new bash session using sudo, which will start a pseudo-administrator mode where every subsequent command is executed with root privileges. Moblin users just need to type su followed by their root password to get the same thing.

The contents of ‘/sys/class/backlight/’ should look something like ‘acpi_video0’, but this is dependent on the kernel driver for your hardware. Beneath this directory, you’ll find a special type of file called ‘brightness’. If you probe the value of this file by typing cat acpi_video0/brightness, for instance, you’ll see the current brightness setting for your screen. This is usually within the range of 0 to 100, and may jump up in steps that are defined by your hardware’s capabilities. The converse of this probe operation is to pass a value to this special file, hopefully changing your screen brightness in the process. Typing echo 100 > acpi_video0/brightness, for example, will configure maximum brightness, while a value in the region of 15 should be close to your screen’s minimum.

CPU optimisation

We’re going to stick within the /sys subsystem to make a few changes to how the CPU is handled. This can be a rather experimental area to play around with, which may explain why many distributions choose not to enable some of the more optimal modes, but it can be worth the trial and error. It’s also dependent on the features embedded within your CPU. Recent models built around Intel’s newer Atom processors shouldn’t have any problems, but older models may not be so flexible. You should also make sure you’ve got a backup of any critical data on your netbook’s drive before trying things out.

The most important parameter can be discovered by typing cat /proc/sys/vm/laptop_mode. If your machine returns a value of 0, then Laptop mode is currently disabled. You can enable it by typing echo 1 > /proc/sys/vm/laptop_mode. When Laptop mode is enabled, the kernel takes special care only to shuttle data to your storage device when it needs to, saving your battery in the process. You can disable this by swapping the 1 for a 0 in the previous command.

You can get even deeper into how the processor handles tasks by changing how the scheduler works. This is only going to be beneficial if you’ve got a multicore machine, and it changes the way processes are loaded onto each core. Check the contents of the ‘/sys/devices/system/cpu/sched_mc_power_savings’ location. If this is set to 0, your netbook is configured for optimal CPU performance – which is useful for mathematically intensive apps, but not so great if you’re only planning to read a couple of emails. Changing this value to 1 will ask the scheduler to use the threads and processes more efficiently before more are created, effectively saving your other CPU cores from being used and saving energy in the process.

Process pruning

The best thing about a netbook distro is that it is already pruned down to the bare minimum of applications and running processes. There should be very little you can do to improve things here, but there’s never any harm in taking a look. The quickest and easiest way of checking what processes are running is to run the ‘top’ command from the command line. It may look a little perfunctory, but it tells you everything you need to know. It’s called top because it shows you a list of the processes sorted by CPU time, with the highest at the top. This list changes dynamically, and the processes at the top usually include top itself, the Xorg X-Server (which is rendering the graphics on the screen) and maybe the gnome terminal (if this is how you’re running top). You can also remove processes and change their priority, but you need to be careful about this as you could seriously affect the performance of your netbook (and even lose some of your data). The safest option is to look for tasks that are running under your user account: you should be able to see your name in the second column for any tasks falling into that category.

On Moblin 2.0, for instance, we’ve noticed that the Nautilus file manager is used to manage external storage such as USB sticks. Occasionally, especially when you remove a USB stick without first unmounting it, Nautilus is left running, taking up precious CPU cycles. You’ll even be able to see that it’s the process connected to the USB device because this path follows the name of the process. You can remove tasks by pressing [K] to enter Kill mode and then entering the process number. This is listed in the top output below the top line. If you’re running a standard Linux installation, then there are a great number of processes you might want to consider removing. These could include indexing routines, compositing managers, background servers and log file generation. Further information can be found by looking at how the ‘initd’ process works and working out how to disable these services at bootup.

Monitor process power consumption

One of the best tools for monitoring and tweaking your system’s power efficiency is called PowerTop. It’s the electrical power consumption equivalent to the ‘top’ command we used to measure CPU usage, and it should be available through your distribution’s package manager. Moblin users can find it by searching for ‘Power consumption monitor’ in the Add/Remove Software panel. It needs to be run from the command line with system administrator privileges, which means typing sudo powertop for Ubuntu users or su followed by powertop for Moblin.

PowerTop can give you a very accurate indication of how long your netbook will last with its current power usage.

It will take five seconds for the tool to initially monitor your current system, after which it will list the various offending tasks running on your system sorted according to the amount of power they consume. The top section of the tool displays the percentage of time your CPU spends running at a specific speed. More CPU-intensive tasks will switch to a faster power state, which will in turn take more electricity. Ideally, you should expect to spend most of your time in the C4 state (the slowest), with occasional bursts of activity in the fastest state, C1.

PowerTop was originally designed to show which tasks were preventing laptops from entering a sleep state, and it’s still useful for this kind of bug fixing (though hopefully your distro builder has already solved the most serious offenders). This is why you still see the processes listed as ‘Top causes for wakeup’, as these are the events that are interrupting the system.

Unlike nearly every other tool we can think of, PowerTop also displays some useful information that can help you stretch out your netbook’s battery life. If it detects anything that it knows will help, a suggestion will pop up at the bottom of the window. Your adjustment will last for the duration of the current session only, but the tips that PowerTop displays often include instructions on how to make each change more permanent.

Proper sleep function

Suspending your machine by closing the lid and then opening it again seldom has the desired effect with Linux. It’s often easier to just turn the machine off and on again. Things are a lot better than they were, but hibernation is one area of the kernel that remains problematic. The difficulty is that each piece of hardware within your system needs to respond predictably to the sleep call, and this requires well-behaved drivers that have a good understanding of their hardware capabilities.

Unfortunately, this can’t be said for many Linux device drivers – in particular those for graphics cards. The only exception is hardware developed by Intel. Intel has made a big investment in Linux, and it continues to make massive improvements to the drivers for its own hardware. The Moblin distribution is the pinnacle of this work, and you should find that sleep works well with most Atom-based machines, as well as those that use other kinds of Intel processors. If you need to cater for hardware from other manufacturers, the best piece of advice we can give you is to make sure that your kernel is as up to date as possible. Things are changing all the time in the Linux world, and you may find that any problems have already been fixed with a kernel update.

Windows Vista was not very well taken in the market by consumers at the official launch of Windows 7 launched after their product review of every 3 to 4 years.

“Windows Vista was not very well taken in the market,” said Andrew Waititu Microsoft License Compliance Manager for East and Southern Africa.

Speaking in a interview, Waititu said Microsoft has had one of the biggest test users on Windows 7 of about more than 8 million people from the market and feels that this is what has built Microsoft.

“I have been using the product for 6 months. The management of power on my laptop is much better and accessing of documents is much easier. The search engine is also very good as it brings up everything in the,” explained Waititu.

Meanwhile a test user of Windows 7, Rex Mumba an IT proffessional found Windows 7 painless to install.

“Out-of-the-box driver support on our test machine was perfect, and it took only half an hour and two quick reboots to begin running a stable desktop environment, though we wondered why Windows 7 created a 200MB partition in addition to its main partition. The 33MB of updates quickly came down the pipe upon loading the desktop,” he said.

Mumba explained that Windows 7 power-management technologies has provided the platform and processor efficiencies that reduce power consumption, helping lower energy costs.

In a Press release, Windows 7 for installation on new computers and for purchase was in computer retailers across Zambia. Windows 7 is Microsoft’s newest version of its popular Windows desktop operating system, which promises to be the best yet to be distributed by the company.

More than a billion people around the world, of every language and every culture, use Windows every day at work, at home and on the go.

As each version of Windows was released over the years, more features, better ways of working together with team members, staying in touch with friends and family, and general computer usage have been refined and simplified to allow almost anyone to quickly learn how to use a computer.

With Windows 7, Microsoft has taken this level of improvement one step further. A billion Windows users worldwide gave Microsoft a great opportunity to listen and learn. That is how the company developed Windows 7.

“Windows 7 represents years of in-depth listening to our customers and partners around the globe, and is the most well-researched, well-planned Windows release ever,” said Louis Otieno, Country Manager for Microsoft East and Southern Africa.

“In fact 91% of Windows 7 Release Candidate testers told us they would recommend Windows 7 – we are incredibly excited and humbled at the response so far,” he added.

No matter where users intend utilising Windows 7, it has something for everyone:

For consumers – Microsoft designed Windows 7 to be more reliable, more responsive, and to make the things customers do every day easier.

For small to medium sized businesses – Windows 7 is the best operating system for work, whether people work from their company office, from home or on the go. Windows 7 works the way you want, enables you to get more done and keeps your work safe.
- For enterprises – Windows 7 was designed to meet the rigorous demands of the enterprise. It makes users productive anywhere, delivers enhanced security and control to reduce risk, and streamlines PC manageability to reduce costs.

Microsoft’s partners in Zambia who sell and distribute Windows 7 are excited at the opportunities Windows 7 will bring.

Microsoft has developed different versions of Windows 7 to cater to for the different things people want to do with their PC:

Windows 7 Starter and Windows 7 Home Basic – ideal for first-time PC-buyers or those looking to purchase a PC loaded with Windows 7 on a budget.
