Let's get rid of usernames and passwords for good

Usernames and passwords annoy me. Expert advice says to have a different username and password for various services, but the amount of subscriptions, email accounts, social networks and other sites we subscribe to can run into the dozens, if not hundreds.

Password managers help, and single sign-on solutions for an array of sites are useful, and devices like smart cards and biometric devices save us remembering a whole array of combinations. But what if you’re away from your primary computer? You still need to remember all of the sequences and mishmashes of letters and numbers whether you like it or not.

Facebook Connect has helped me out greatly. On my home computer, I never sign out because there’s just no point as nobody else lives with me (thank God), and on my office computer, I always lock my screen so again, no need to log out. With this, it means I can not only sign in straight away to supporting services but it means I can cut down on the number of user names and passwords I need.

Perhaps it is time we worked on a new system. No longer should be need to push the “forgot your password?” link, or have to look up a long list of passwords in the filing cabinet, or even have to rely on a browser to take the workload for us. There needs to be a solution.

OpenID has the right idea, but it works in a similar way to university federation services and doesn’t really share any unique factor. Even CBS Interactive sites like ZDNet, TechRepublic, and BNET have a good idea by sharing the same login details across sites so you don’t need to re-register. But again, this isn’t enough.

I’d like something to change but simply don’t see a system being implemented which wouldn’t cost about a zillion dollars. For now, this thirty-year solution may have to stick with the byline of “if it ain’t broken, don’t fix it”. Then again, Google thought e-mail was broken when it brought out Wave…

How would you fix it?

On 7th July 2005, fifty two people were killed when four suicide bombers detonated home made explosives on the London Underground. During this time, there was panic, confusion, miscommunication and a number of issues relating to where to go and what was going on. Even law enforcement suffered making the situation even more fragile.

With experience of hindsight, with a number of events which social networking from ordinary members of the public (”citizen journalism”) from the terrorist attacks in Mumbai, the Hudson river plane crash and the death of Michael Jackson; Twitter especially has been a key point of communication.

Mumbai was a perfect example of how Twitter dominated the intelligence gathering process, using real people and human intelligence but through an unconventional, insecure medium. Photos were being uploaded to Flickr and Twitpic, and tweets were dominating the blogosphere, and being used as part of commercial news channels as their own journalists simply couldn’t be spread thinly enough.

However in the case of Mumbai, public and very widespread intelligence could have been used to the terrorists’ advantages, also. Not so much the case of the London bombers, though.

How could it have helped London?

Windows 7's first 100 days: So how were yours?

Posted by Zack Whittaker @ 6:35 am

It has been 100 days since the release-to-manufacturing copy of Windows 7 was available for download on MSDN and TechNet. I’ll put this very simply: I have never used an operating system which works so well, is as stable as it is, is aesthetically pleasing, and is a pleasure to use still even after three and a bit months.

There is nothing within Windows 7 which is particularly aimed at students or me specifically. The whole kit and kaboodle focuses on making it an all-inclusive “experience”, but after using it for so long now the experience fades into the background, like a sickly cough in a lecture theatre.

At the end of the day, all you want to do is check your emails or whop out a quick essay. You don’t particularly care about the experience and most of the time you don’t notice the surroundings. Even with Windows 7, this hasn’t changed.

Besides my computer going well and truly kaput, the way I noticed my positive experience so far is through the lack of negative experiences. I’m lucky in that I took advantage of pre-release builds and have seen Windows 7 grow from a small, insignificant Vista rip-off, into a mature, upstanding member of the technology community.

There is only one nit-picky thing that I still struggle to shrug off. The memory usage is far better than Vista but has a long way to go until it reaches levels that XP coped with. Even with a base level of applications open: Outlook 2007, Messenger, Skype and DisplayFusion to maximise my taskbar space, but it still looks like it uses more than it should. On a 4GB RAM system (in 32-bit mode, so only 3.5GB is really recognised), I’m still using 1.10GB on a dual screen system.

I understand why, as I have two screens and the Aero theme takes up quite a lot of memory usage, and doubled it naturally doubles (ish) the memory usage. But I like to keep my memory usage down as much as possible; at least that way I don’t hear my tower whirring away and going nuts.

The feedback I have had from other people, friends and colleagues, may seem somewhat cliched. But all have had a positive attitude towards it when mentioning it in passing. “Oh, Zack, by the way, Windows 7; I like”, for example. Seeing it running on my friend’s computer in a 24-inch crystal clear LCD screen combined with his justified semi-smugness about being one of the few, even still, to have the operating system on his computer, being another.

All in all, I’m extremely happy with everything as it is and how it works, what it does and when it does it. But what I say isn’t too important. How were your first 100 days?

Cloud storage: Impossible to fill?

Posted by Zack Whittaker @ 3:00 am

There are vast numbers of online storage solutions, services and products at the moment. More often than not they’re free, being paid for through advertisements, and most offer a number of gigabytes; some into double figures.

But taking a look at a random selection, some including email services like Gmail and Hotmail (which offer very much the same thing in a different format), are they giving us too much storage? Are the cloud storage providers giving us infinite capacity?

Side note: semantics and technicality could shoot me in the foot here. When I mean “infinite”, I do not mean a never ending supply of data storage, rather the storage we currently have in the cloud will never be filled by us as individuals.

Take SkyDrive as a perfect example. Even though you have 25GB at your disposal, you can only upload 50MB at a time. There seems no logical reasoning to this, with the possible exception of not being able to abuse the storage for uploading of illegally downloadable films and videos. However, this restricts you somewhat.

If it were to be fully open, you could literally drag and drop an entire system image into your cloud and take it anywhere with you. Then again, you can create a restore image and use WinRAR or HJSplit to cut them into tiny 50MB sized pieces and upload manually.

I don’t think every user truly has 25GB space, though. It would make logical sense for the “drive” you have to be a dynamically expanding (virtual) hard drive. If every user used their 25GB today, the datacenters would be overfilled by tenfold no doubt.

The point is, as most online cloud services offer these vast storage quantities, you are restricted in how much you can upload in one go; this makes it ideal for documents and music files, but not for massive files like movies and large videos.

The same applies to Gmail, of which emailing something to yourself acts as pretty much the same concept. The 25MB limit is purely coincidental, but limits the user once again.

Using this time calculator, my own connection, a stopwatch on my phone and a bit of graphics editing, I’ve concluded to fill up a 25GB drive such as SkyDrive, it would take you:

… and that’s continually, without sleep, walking the dog or even going for a pee. Although, I guess maybe you could pee during the upload, but you get my point.

Still, you could always bypass the whole system and map your cloud storage to your other local computer and drag and drop that way.

Has cloud storage become unfillable?

Paperless students? Never going to happen

We live in an age where technology is rife. We cannot escape from mobile phones, computers, netbooks, projectors, e-readers and the rest of it. But students simply couldn’t go paperless. The chances are it’ll never happen, or at least if it does, when I am long gone, dead and buried.

The argument for going paperless is stronger than ever, with learners wanting less paper and more technology, and teachers wanting less paper to manage and deal with.

But this is schoolchildren we are talking about, not university students. Students in higher education relish using paper; allowing them to spread their thoughts across multiple pages and across multiple work surfaces.

The incentives are there; every time I print something off at university, because I need to use my university username and password to print, it records when I do so. But every print-out leaves me with a pop-up guilt trip reminding me of how much of a tree I’m destroying in the process.

Forget computer science students because they are a minority at most institutions. Of course they will be using their netbooks, Androids, smartphones and iPhones to tap away at during a programming lecture. But the rest of the students on campus are more than happy with scraps of paper, Post-it notes and lined paper with scribbles on. The rest of the campus doesn’t engage with technology on an everyday basis so they are not missing out in the first place.

For this, when writing up the notes later into electronic format, we can have a sense of satisfaction about screwing up the paper and chucking it away.

How would you write notes onto a PDF file? Yes, you could use a touchscreen computer, but handwriting recognition isn’t an exact science yet and a pad of paper and a Biro pen are far cheaper.

Taking books out of the library aren’t always possible. Sure, we could grab our Kindle and download the book but why should we when we are spending thousands of our respective currencies on library provisions? Some books are only available for an hour at a time, so instead of scanning them into a computer for later analysis, photocopying is a more sensible solution. Those who remember will know that I have proven this one long ago.

In realistic terms, the only computers students want to use is the one computer that they are using to write their essays on. Besides that, technology has yet to really have a major impact on the main brunt of our degree courses - the discussion seminar - where all you need is your mind and your mouth.

Me? Personally? Many can testify to this. I would be far happier with a handful of notes, scribbles and scraps than a netbook. Would you rather go paperless?

10 technological changes in 10 technological years

My goddaughter is now of an age where she can talk, understand, and learn pretty well. She’s six, so she’s pretty on the ball with things already. The things that she experiences and sees are so different to mine, and she’s only 16 years younger than me. Times change quickly, I know, but it hit me like a wave of elderly welfare benefits disguised as a petrol tanker last night.

The differences between her generation and mine, even though separated by a few years, are stark and somewhat terrifying in hindsight.

1. There were nine planets in the solar system.

For years it was always nine planets and then one day, they decided it was either going to be eight, or about twenty. They chose eight. After seven years of primary education, the world I knew it was, well gone actually; they had just declassified it as a planet.

2. A BlackBerry was a fruit, and so was Apple.

I wouldn’t be too surprised if people heard either “blackberry” or “apple” and genuinely thought of the fruit. But I cannot seem to shake the association now built with my mobile device. People say, “have at least one of your five a day”, whilst I have my BlackBerry in my hand making a call. I’d say that counts, right?

3. To load up a program, you’d have to slam in a cassette tape and wait 20 minutes for it to load.

My first computer, a CPC-464. It was so heavy you could have used it as a concrete block in a mafioso novel. A ten year gap is a bit of an exaggeration but I knew people still word processing back then on green-screened computers. When the 5″ floppy disk came out, we saw that as a mini-revolution in itself.

4. You had to dial into the Internet.

You couldn’t just have the Internet flowing in and out of the computer like an out of control waterfall. No, you had to tell it to dial another computer and information would be sent to and fro through, what was essentially a computer-to-computer phone call. What’s even more weird is that it’s still available, even today.

5. A single gigabyte hard drive simply couldn’t be filled, through no will of trying.

My first computer bought for the family at Christmas 1996 (yes, it had Windows 95) had a 64MB memory and a single gigabyte of storage. My dad said, “we will never, ever fill that”.

6. Video tapes the size of Bibles would be the only way to record a television programme, and even then it’d only be able to record an hour and a half at best.

Even though I’m far too young to remember the Betamax vs. VHS war, I most certainly remember hoping to watch back an episode of The Simpsons which I’d recorded on the oldest VCR in the world, and it failing miserably with tape lodged and jammed in every bit. It was heartbreaking.

7. The only porn we could find was the shredded remains of a dirty magazine under a bush in the local park.

This generation of Internet kids has seen more porn than any other generation of children, ever. When I was a lad, one morning you’d be lucky enough to find a shred of it near where the local dirty old man sleeps in the evening. “Kids having kids… blame the parents”: no, blame the Internet.

8. There was only one computer in the house, and if there were more, only one would connect to the Internet at a time.

No such things as wireless back then. The only wireless you’d know of was the radio, and that would have been a main source of entertainment. It may sound like wartime England, 10 years ago wasn’t that far away. Windows XP hadn’t come out yet, I was still in a school uniform and the computers we used were running Windows NT.

9. There were no such things as flat screen televisions.

At least commercially, anyway. I come from a generation where our eyes are slightly closer together yet facing slightly the opposite way from being transfixed by a CRT television for all these years. And I laugh now at the “radiation warnings” from the sticker on the side of the box…

10. Twitter was called “text messaging” and the “tweet” only went to one other person.

Yes, a new phenomenon which many don’t realise that was basically text messaging. While sending a text is still far more popular than Twitter, the days where news would slowly seep its way through a friendship group (nowadays a “social network”), whereas now you can update literally anyone and everyone in the space of 160 characters.

A lot can happen in ten years.

Facebook profile privacy: Take control, student style

A question arose in one of my seminars yesterday, asking whether universities spy on students through Facebook.

Yes, they do in many cases. But then the discussion evolved into another topic and this got me thinking. I get emails all the time asking about Facebook privacy settings and those who are worried about certain things being discovered, and the employment problems for future reference.

With the multitude of settings, and more often than not rather confusing and somewhat contradictory, how do you effectively lock down your photos, notes, profile and information, to not only certain people but everyone else outside your close-knit networks?

There are articles already on how to lock down your Facebook through the in-built settings, and this one is particularly good. However there are tricks and subtleties I’ll mention here which you may not have considered before.

Feel free to leave verbal heckles, but in the meantime - are you sitting comfortably? Shall we move on?

MI5, an ISP lawsuit and an e-petition: More opposition to piracy cut-off plans

There has been more controversy this week with a major Internet service provider, a petition set up to harness the power of democracy, but also the British Security Service, MI5, all opposing the cut-off laws which are being pushed through by a key figure in the British government’s cabinet.

The Digital Economy Bill, which will be brought to Parliament in the next few months, began with a good intention to bring positive change to how the country’s primary source of communication was run and would continue to work, such as:

“…delivering a universally available broadband in the UK by 2012 through a public fund, including funds released from the digital television switchover help scheme.”

However, Peter Mandelson, the Business Secretary, is trying to use this legislation to follow through his apparent own agenda to fight illegal file-sharing in form of cutting offenders off the web for the maximum of a year.

Both intelligence services, MI5 and MI6 have “voiced their concerns” regarding the disconnection of citizens who are found to be file-sharing as it will make monitoring and surveillance far more difficult, while police and major law enforcement units in London are concerned due to the amount of evidence that will no longer be able to be collected as a result of these bans.

• Read more: Student suicide threat over RIAA bullying tactics
• Read more: Downloading content illegally vs. getting away with it
• Read more: Universities in hot water over students’ peer-to-peer sharing

It is important to say that Mandelson does not see “widespread account suspension” resulting, and that the “technical measures” (cutting off the Internet to offenders) will be a “last resort”.

Meanwhile, TalkTalk, a major ISP in the UK with ownership rights over Tiscali and AOL and serving over four million users, are threatening legal action against either the government for enacting the policy or even Mandelson directly.

Last month the ISP, who are massively against the three-strike plan, demonstrated how with many unsecured wireless networks still existing, how easy it would be to download illegal content or media through another connection.

With this, Andrew Heaney, TalkTalk’s executive director of strategy and regulation, has taken advantage of the Government’s e-petition service, asking the prime minster to:

“… abolish the proposed law that will see alleged illegal file-sharers disconnected from their broadband connections, without a fair trial.”

If you have or had British citizenship, you are more than welcome to sign the petition which can be found here.

As and when news develops on this rather interesting and somewhat personal topic, you’ll find it here.

One second: The time it takes to wipe three years of work

It only takes a single second, some would argue a micro-second, to wipe an entire hard drive. Without the need for electromagnetic pulses or an industrial liquidiser, all it takes is a single spark of electricity to cause havoc with your entire electronic life.

How do I know? Because last night I hit the realisation that I lost everything in a blink of an eye. Here’s how, kids.

Two days ago, I was in my home office working on my degree work for the week. Just as I finish writing up a seminar, I stretch my legs, kicking out the all important power cable at the back of my machine. It’s not the first time I’ve done it, so I was annoyed at potentially losing what I had been working on but not particularly fussed. Read the rest of this entry »

Windows 7 puts Vista into perspective: Only a 'failure' in retrospect

For my 400th post on ZDNet, this is one mass response in reply to a barrage of emails I have had to suffer over the course of the last couple of weeks.

It seems as though I, and the just-over ten thousand students on my university campus, are not the only ones complaining even still about the abomination that their respective university IT department, hand in hand with the devil itself, Microsoft, have bestowed upon us: forced through product lifecycle periods to upgrade our campus to “the latest and greatest”. Feel free to detect any element of sarcasm in the last sentence.

Only short two weeks ago, I had high hopes for the upgrade. I genuinely thought that a new lease of life could be drawn through the lungs of Microsoft’. I was not only wrong, but overly optimistic.

For those who have been reading since day one, I started with a touch of empathy towards the then-new operating system. Over time, and predominantly over the course of Windows 7’s beta cycles, I became more attached to the lack of resource hogging, sluggishness and a general freshness which could only be rivalled by that of a gentle breeze on a summer’s day in the countryside.

But I did start off with a very good point. Vista back in the day was perfectly fine. Only in comparison to a better benchmark of Windows 7 do we start slating the former operating system. Something that widely popular blogger, Long Zheng, mentioned earlier on this morning on Twitter was this:

To begin, I start with the question as mentioned in the title. From there I hypothesise the potential failure of Windows 7 and look into the few people we can blame for the potentially epic failure of Microsoft’s next operating system.

Who do we blame for Vista, and Windows 7’s potential failure? –>
