Universities have bogus students shock

I’m shocked, shocked to find that gambling is going on in [this casino]! (Captain Renault, Casablanca, 1942)

The UK Border Agency has finally acted to revoke London Metropolitan University’s “Highly Trusted Sponsor” status, which allowed them to grant student visas.

This is very tough luck on the genuine foreign students that happened to be doing a course there when the music stopped, and my sympathies are with them. But this system has been living on borrowed time for far too long. As far as I can make out, London Met is no better or worse than any others, and according to staff there who I’d tend to trust, has actually tightened up considerably after the first complaints and is probably less deserving of a foreclosure than most. There but for the grace of God go all the others.

Back in the late 1990’s the then New Labour government decided that everyone should have the chance to get a university education, so created a lot more university places by creating a lot more universities (and introduced student loans and tuition fees to pay for it). The snag is that tuition fees don’t cover the cost and the new universities don’t have their own income, so the only way to expand and prosper is to attract foreign students, whom you can charge what you like. Other than academic integrity, commercially:

  • There is no incentive to ensure that the students are pre-qualified (or even speak enough English to cope).
  • There is no incentive to ensure that students would benefit from the course.
  • There is no incentive to ensure standards are maintained (if you fail too many, they’ll go elsewhere).
  • There is no incentive to ensure that student’s paperwork is genuine.
  • There is no incentive to ensure that students actually attend the course.
  • There is an incentive to keep quiet, because there are academic jobs are on the line.

With a system where every incentive is to create abuses such as this, who can be surprised when they happen. Don’t forget, these universities are run as businesses with business managers – they’re not run by the academic staff.

I’d be very surprised if London Met was the only university to receive this attention in due course. It’s not that anyone deliberately set out to pull a fast one, but if the incentives are stacked the way they are then you’re going to get a culture of looking the other way.

The Border’s Agency investigation found that in a sample of 250 students at London Met, 25% had no valid visa, 56% had “attendance problems”, and 40% couldn’t speak English well enough to do such a course. But the same system also encourages universities to sign up domestic students and not fail too many, as this is the basis on which they’re funded. They’re paid for each student who completes the course (a lesser amount if they drop out), and students make a terrible fuss if they fail to pass and tell all their friends to avoid the place, reducing intake. If  standards are ever questioned, you’ll find plenty of academics willing to appear on camera to say otherwise, and what else could they do if they want to maintain the status quo (i.e. their jobs). But the incentive is to push standards lower.

It’s very frustrating for those working in higher education for fight against this tide, and ultimately it’s doing the country no good. It’s described as a great export earner – do we really want to be exporters of dodgy degrees? The UK Border Agency’s move is a good first step to stop the rot, but it seems to me that London Met is the scapegoat and what’s really needed is a good long look at the whole system starting at the top. This correct course of action isn’t likely to be a vote-winner with the students.

 

eBay are now worse than whores – ask any business seller

eBay are whores”. That’s was the verdict of an American friend and regular eBay business seller.

“How so?”, I asked. He went on to explain that eBay and PayPal would do anything for money, and everything imaginable had price attached which you had to pay if you sold through them. My friend was a typical right-leaning free market American, and I had to smile at his complaints about big business doing what it does best. If he wanted to sell his collectable items in an on-line auction it had to be  through eBay, because eBay has an effective monopoly on buyers. eBay was simply obeying the laws of supply and demand; charging the customer (that’s the seller) the maximum they were willing and able to pay without scaring too many away. With an effective monopoly it’s hard to scare them that much.

Since then eBay’s use of its monopoly power has taken a very dark turn indeed, in response to one of their biggest problems: Criminals use eBay. Most of us have bought something through eBay and discovered the seller was less than honest, and eBay feels that this situation is going to adversely affect their revenue in to the future. Recently they’ve declared war on rogue traders, but it such a clumsy manner their actions are immoral and possibly bordering on the illegal.

A few years ago I started hearing complaints from eBay sellers who’d given up moaning about high commission rates in favour of how eBay was making it very easy for buyer’s to defraud them. This started with PayPal, the no-longer-so-optional money transfer system now owned by eBay that sellers are pressured in to using. If a criminal orders something, pays using PayPal and once they’ve got the goods decides to complain (or claim the goods never arrived), PayPal takes the money back from the seller, with no effective mechanism for appealing. As I understand it, the seller has to prove that the buyer received the goods before they get their money, and this just isn’t realistically possible in many circumstances.

PayPal and eBay hardly invented mail order fraud, but they’ve made it very easy for the criminals. Banks would investigate in the case of such a dispute, but by all accounts, eBay does not. All the seller could do was leave negative feedback against the buyer, so future sellers were forewarned and could make up their own minds about dealing with someone.

In the latest twist, sellers can no longer leave negative feedback about buyers, effectively allowing buyers to lie and cheat as much as they wish with no risk of exposure or other consequences. Sellers have to quietly absorb the loss while the criminal selects his next victim.

You may think this is as bad as it could get, but now eBay has implemented what it calls “Detailed seller ratings”, aka DSR. Basically buyers can (anonymously) rate sellers out of five for things like accurate description and delivery time. If a seller gets, on average, less that 4.6 out of 5 then they encounter difficulties with eBay. Sellers have told me that they receive letters saying that they “need to improve”, followed shortly afterwards with having their accounts suspended indefinitely “to protect buyers”. Does everyone apart from eBay see the problems here?

Firstly, there are some very strange people out there. If they don’t like what they bought they’re going to give the seller a bad rating for everything.

Please generate and paste your ad code here. If left empty, the ad location will be highlighted on your blog pages with a reminder to enter your code. Mid-Post

Secondly, many people are unlikely to give anyone 5/5. At one time, my job was reviewing things. I did it every day, and I’d never give anything 100% unless it was incapable of improvement. With eBay the next step down is 80%, which by normal standards is very good indeed. However, on eBay’s DSR system, if someone gets to many 80% ratings their account gets suspended!  At one time I didn’t know that, so I’d routinely give everyone a score of 4 unless there was something extra-special about the service. Most people writing a review would do the same.

Finally, this is a recipe for scamming. Supposing you and a competitor were both selling the same thing into a niche market. eBay was excellent at niche market products, once. Unfortunately, in this cut-throat  online market place, if you’re not the cheapest you’ll lose the business, but if you sell at rock bottom you make no profit. So what can you do? eBay has the answer – simply ask a few of your friends to buy items from your competitor and then give them consistently bad DSR scores. eBay will shut them down for you, with no right of appeal, and the way is now clear for you return to your full profitable prices. In the good old days you had to hire a bunch of thugs to beat up your competitors and burn down their premises  now you can get the same effect with a few clicks of a mouse. If someone else appears selling the same thing, they’ll have a “unknown” rating anyway, so a couple of bogus purchases and they’re out of business. This works; I’ve seen the victims and I’ve seen eBay’s attitude to doing anything about it.

Sellers are in a very difficult place. If eBay closes their account, they’re out of business. It’s high time eBay was taken to court over this matter, that of putting British companies out of business for no reason. Unfortunately eBay is hiding behind a flag of convenience. Although it says “ebay.co.uk” on the web site, they’re operating through Luxembourg (and challening the profits through Switzerland to avoid UK corporation tax). Taking them to court isn’t going to be easy.

In the USA, where the jurisdictional is less murky,  there have been several class actions against eBay In response, eBay has altered it’s user terms and conditions such that everyone has to agree not do this any more.

I think it’s high time that eBay developed a sense of responsibility towards the countries that are allowing it to operate. It enjoys a effective monopoly position, yet companies needing to use it are ruined at the whim of a some faceless functionary within eBay, who might be in any part of the world. Power without responsibility is always a bad thing. If that’s not enough to make our government take action, they should consider industrial-scale tax avoidance scheme eBay is employing.

 

 

 

Western Digital Red Series review

I’ve got a SATA drive throwing bad sectors – not good. Its a WD Cavier Green, and it’s about a year old. But I’ve hammered it, and it was cheap. An IDE drive throwing bad sectors is never good –  once the problem is visible it’s on the way out. I doubt WD would replace it under warranty as its not on a Windows box and I therefore can’t download and run their diagnostic, but we’ll see about that.

And anyway, Western Digital  launched the ideal replacement two weeks ago – the Red series. Unlike the Green, it’s actually designed to run 24/7 – cool and reliable. They’re pitching it squarely at the NAS market, for RAID systems with five or less drives, they say. Perfect, then. And a good market offering given that last month’s IDC low-end storage forecast predicted an 80% gowth in the small/home office NAS market over the next five years.

The Red series launches with 1Tb, 2Tb and 3Tb versions, with 1Tb on each platter.

I checked the specifications with scan.co.uk – 2ms access times too! Lovely! Hang on, that’s too damn good. I suspect someone at Scan has gone through the specification sheet to add the access time to their database and found the only thing on the list measured in milliseconds. Actually it can withstand a 2ms shock! WD doesn’t mention the access times, or the spin-speed come to that (about 5400 given the hum).

Well, having now checked one of these beasts out, the access times are obviously something they’d want to keep quiet about. In comparison with the Cavier Green, which is supposed to be a low-impact desktop drive, it’s about the same on writes and about 30% slower on reads. However, once it’s in position it is about 30% faster streaming. This would be handy for an application where single files were being read, but not so brilliant if you’re jumping about the disk at the behest of multiple users – which is the intended market for this thing. Real-world performance remains to be seen, but I don’t think it’s going to be as quick as a Cavier Green, and they’re slow enough.

So why would anyone want one of these?

Compared to the Cavier Green, the red is rated for 24/7 use. Compared to the Black series, or anyone else’s nearline drives, its performance is terrible, but it is cheaper and much cooler with a lower power consumption.

If you want performance at this price point the Seagate Barracuda drives are cheaper and a lot faster, but Seagate don’t rate them for continuous use. The Hitachi Deskstar, on the other hand, is rated for 24/7 operation even though it’s a desktop drive and it outperforms the WD Red by quite a margin too. But hang on – WD recently acquired Hitachi’s HD operation so that’s a WD drive to. So for performance go for the Baracuda and for best performance running 24/7 go for the Deskstar.

The WD Red is basically a low-performance near-line drive except that it’s  not, actually rated as being as reliable as the real near-line drives. But it is claimed to be more reliable than the Green series, and they do run just cool and just as quiet (subjectively). Is it worth the 35% price premium over the Green? Well, actually, sitting here with a failing Green, the Red with the three-year warranty is looking attractive for my data warehousing application. This isn’t NAS, it’s specialised, and I need low-power (cool) reliable drives to stream large files on and off. They could be just the job for that.

As an afterthought, comparing them with the Black, they also lack the vibration sensors to protect them in a data centre environment or a box chocked full of other drives. The idea of putting them in a rack server as a low-power alternative looks less attractive than it did.

Using ISO CD Images with Windows – Burn.Now problems

When CD-R drives first turned up you needed special software to write anything – originally produced by Adaptec but they were soon overtaken by Nero, with NTI and Ulead having lower cost options. Now, when you get a PC it will usually come with one of the above bundled, and Microsoft has added the functionally to Windows since XP (for CD, if not DVD). This is not good news for the independent producers, but Microsoft’s offering doesn’t quite cut the mustard, so most people will want something better.

My new Lenovo PC came bundled with Corel Burn.Now. Corel recently bought the struggling Ulead, and this is fundamentally the same product as Ulead burn.now. Unfortunately Burn.Now is also pretty feeble – it just can’t do the basics.

To duplicate a CD you need to copy all the data on it. Pretty obvious really. If you’re not copying drive-to-drive it makes sense to copy the data to a .ISO image on your hard disk. You can then transfer it to another machine, back it up or whatever; and write it to a new blank disk later. Burn.Now will create a CD from an ISO image, but if you ask it to copy a disk it uses its own weird and whacky .ixb format. Some versions of Burn.Now gave you the choice, but not the new Corel. It’s .ixb or nothing. This matters, because whilst everyone can write .ISO files, only Burn.Now can write from  .IXB format.

Burn.Now is crippled. What about Microsoft’s current built-in options? You can actually write an ISO image using Windows 7 – just right-click on the file and select “Burn disc image”. Unfortunately there is no way to create such a file with Windows. To do this you need add Alex Feinman’s excellent ISO Recorder, which basically does the opposite: Right-click on the CD drive and select Create Image from CD/DVD.

Unfortunately ISO Recorder doesn’t read all disks – it won’t handle Red Book for a start. This is a bit of a limitation – was its author, Mr Feinman concerned about music piracy? Given Windows Media Player can clone everything on an Audio CD without difficulty, his conciousness efforts won’t make a lot of difference.

So – Windows is its usual painful self. If you just want to simply create an image of a CD or DVD with no bells and whistles, go to UNIX where it’s been “built in” since the 1980’s (when CD-ROMs first appeared). Just use the original “dd” command:

# dd if=/dev/acd0 of=my-file-name.iso bs=2048

An ISO file is simply a straight copy of the data on the disk, so this will create one for you. You can write it back using:

# burncd -f /dev/acd0 data my-file-name.iso fixate
Or
# cdrecord dev=1,2,3 my-file-name.iso

Burncd is built in to FreeBSD (and Linux, IIRC), but only works with atapi drives. In the example it assumes the CD recorder is on /dev/acd0 (actually the default).

Cdrecord works with non atapi drives to, but has to be built from ports on FreeBSD and for other platforms it’s available here – along with lots of other good stuff. The example assumes the device is 1,2,3 – which is unlikely! Run cdrecord -scanbus to locate the parameters for your drive.

Once you have your ISO file, of course, you could use Windows to write it. The choice depends on whether you have strongly held views on whether Windows is a worthy desktop operating system. Corel Burn.Now is, however, a long way from being a worth CD/DVD writing utility.

Samsung’s (Pyrrhic) Victory in Galaxy vs Apple iPad Case

British judge Colin Birss has struck a blow for the rest of the world against Apple’s litigious tendencies towards anyone any everything their lawyers decide has enough money to sue. Apparently, the 9th July ruling (Samsung Electronics (UK) Limited & Anr v. Apple Inc., High Court of Justice, Chancery Division, HC11C03050) requires Apple to put a notice on its UK website and take out advertisements in a large selection of newspapers and magazines stating that Samsung’s Galaxy tables are not a copy of Apple’s iPad, contrary to what Apple has been claiming in court. Apple is, apparently, appealing.

Samsung Galaxy Beam
Samsung Galaxy handset – not like an iPad

As part of the ruling, the judge said that Samsung’s offering was “not as cool” as an iPad. Although I’m at a loss as to what the legal definition of “cool” might be, it’s clearly relevant in a non-legal sense. iPads are “cool” as far as the fanbois are concerned, and unreliable yuppy status-symbols for the rest of us. If we want a tablet for any reason we’ll base the decision on price and support, not brand image.

iPad - too cool to be a Galaxy
The Apple iPad is much cooler than the Samsung Galaxy. Apparently.

So – the judge is telling Apple it must tell the world that the Galaxy isn’t a clone of the iPad. Surely Apple’s problem is potential customers lusting after an iPad but then opting for a cheaper Samsung alternative. That the Galaxy is not the same as a cut-price iPad should be something Apple shouts from the rooftops anyway. All their current rhetoric, that the Galaxy is an iPad clone, is playing into Samsung’s hands.

Lunar Lander (LEM) – original BASIC/FOCAL version

One of the most popular games of the late 1970’s was Lunar Lander (also known as Rocket, LEM, Apollo and what-have-you). The general idea was always to land a Lunar Excursion Module (LEM) on the surface of the moon (or other planet) by adjusting the burn rate of retro-rockets in order to control deceleration and effect a nice soft touchdown.

The version presented here uses a set of calculations based on a program called LUNAR written by Jim Storer for the PDP-8 while a student at Lexington High School in the USA in 1969. It was converted from the original FOCAL into BASIC by Dave Ahl (then publisher of Creative Computing magazine) in the late 1973.

As far as I can tell, I have disentangled the calculations well enough to preserve the original’s look-and-feel, though it required a complete re-write for Java (which does not support the GOTO statement for program logic flow control). I couldn’t say that the calculations are accurate to life, but a good attempt at realism was made in the original. If anyone from NASA would care to comment please drop me a note.

Heath User Group Camel Game (Creative Computing)

This is the Camel game wirtten in the late 1970’s by the Heath User Group and published in Creative Computing. The original is in basic – this is a re-write in Java keeping as close to the original as possible.

Dodgy “bulk email” operators

I’m forever receiving emails from “bulk email” companies that claim to be “opt-in” but are using addresses that are culled from elsewhere. The elsewhere basically means they’re not real email addresses and could not possibly have been the subject of an opt-in.

After replying to these with an unsubscribe request (on the assumption that they might be legitimate, but have accidentally purchased a dodgy list) I though I’d list them here if the emails don’t stop.

If your name is on this list and you think you’re innocent and can prove it, it will, of course, be removed. If the mail header shows it’s coming from your server and you’ve ignored unsubscribe requests you can explain why. Your protestations will be published along with the other evidence, and Internet users can decide your innocence or guilt.

Panicky public gets scammer’s charter for cookie law

Are you worried about websites you visit using cookies? If so, you’re completely wrong; probably swept up in a tide of hysteria whipped up by concerned but technically ignorant campaigners. The Internet is full of such people, and the EU politicians have been pandering to them because politicians are a technically illiterate bunch too.

A cookie is a note that is stored by your web browser to recall some information you’ve entered in to a web site. For example, it might contain (effectively) a list of things you’ve added to your shopping cart while browsing, or the login name you entered. Web sites need them to interact, otherwise they can’t track who you are from one page to another. (Well there are alternatives, but they’re cumbersome).

So what’s the big deal? Why is there a law coming in to force requiring you to give informed consent before using a web site that needs cookies? Complete pig-ignorance and hysteria from the politicians, that’s why.

There is actually a privacy issue with cookies – some advertisers that embed parts of their website in another can update their cookies on your machine to follow you from one web site to another. This is a bit sneaky, but the practice doesn’t require cookies specifically, although they do make it a lot easier. These are known as tracking cookies. However, this practice is not what the new law is about.

So, pretty much every small business with a web site created more than 12 months ago (when this was announced) or written by a “web developer” that probably didn’t even realise how their CMS used cookies, is illegal as from today. Probably including this one (which uses WordPress). Nonetheless, head of the ICO’s project on cookies, Dave Evans, is still “planning to use formal undertakings or enforcement notices to make sites take action”.

What’s actually going to happen is that scamming “web developers” will be contacting everyone  offering to fix their illegal web sites for an exorbitant fee.

The ICO has realised the stupidity of its initial position and now allows “implied consent” – in other words if you continue to use a web site that uses cookies you will be considered to have consented to it. Again, this is a nonsense as the only possible problem cookies are tracking cookies, and these come from sources other than the web site you’re apparently looking at – e.g. from embedded adverts.

So – if you want to continue reading articles on this blog you must be educated enough to know what a cookie is and not mind about them. As an extra level of informed concent you must presumably agree that Dave Evans of the ICO and his whole department is an outrageous waste of tax-payers money. (In fareness to Dave Evans, he’s defending a daft EU law because that’s his job – its the system and not him, but he’s also paid to take the flack).

Claire Perry’s porn prohibition set to make politicians look foolish

The government is going to protect us from pornography on the Internet. Our children will at last be safe from depravity and corruption. Hurray! Claire Perry MP (Conservative) has accused Internet service providers of being complicit in exposing children to pornography and wants something done about it. Specifically she wants ISPs to filter the filth, unless a subscriber specifically wants to receive it. David Cameron has now jumped on her bandwagon, clearly without first checking to see which way it’s heading or whether the wheels are properly attached.

This isn’t going to be popular with the consumers and producers of Internet-delivered pornography, but that’s their problem. What worries me are the technical issues, and the consequences of trying to implement any form of censorship.

Let me make this clear: IT WON’T WORK. There is no technical solution available that can prevent porn from being transmitted over the Internet, and there never will be. It’s simply not possible for a computerised filter to tell the difference between porn and everything else, and it will become much harder if you give people a reason to avoid detection. About the best you can do is block known porn websites, and if the site promoters cooperate (i.e. keep them on fixed addresses) then you’re going to get a reasonable level of protection. And porn publishers, at present, are likely to cooperate. They’ve no interest minors viewing their wares, because minors don’t have the credit cards to pay for it. And besides, it’s a multi-million pound industry which includes many serious people with children of their own and similar concerns to the rest of us.

However, as soon as you start blocking these sites at ISP level, porn publishers will have to change tactics, as they’ll want to evade such draconian filtering. Legitimate producers will suffer; the vacuum will be filled by others underground, joining the leagues of the cyber-criminals, operating from agile addresses on servers operating outside jurisdictions that care. Claire Perry’s bright idea won’t work. It’s not better than nothing; it’s worse.

The porn operators would disguise their sites to avoid the filter, and in order that customers might find them, spam everyone using every means possible as they did in the late 1990’s. Right now you need to go looking to find it – a simple Google search away. If Perry gets her way it’ll be delivered to everyone’s Inbox, Facebook page, Skype and every other instant messaging technology you can think of, It’ll be encrypted and impossible to filter. It’ll be indiscriminate; kids will receive it too. If such a law was enforced, all encrypted content would have to be blocked as there is no way of telling what it is. This means farewell to, Skype, secure connections to your bank, private email, working from home on a VPN… Okay, it’s not realistic as well as being unenforceable.

The Internet dealt with issues similar to this twenty years ago, before the politicians were involved, but if the technicalities aren’t for you (as they aren’t for Perry and Cameron), there are plenty of other parallels. Society’s attempts to ban bad things that some people still want always seem to make things worse. I need hardly mention prostitution, drugs and alcohol, but I will. Making drugs illegal when so many people want to use them has simply improved the margins for the suppliers. Where there’s money to be made, people will find ways to smuggle drugs; and if the whole business is illegal then it’s certainly going to be completely unregulated. And it’s not a lack of resources and commitment. If we can’t stop people supplying drugs to inmates of a high security prisons we stand no chance of banning drugs anywhere else.

Similarly, it’s folly to attempt to ban pornography transmission on the Internet. There is no way to do this technically, and any attempt that simply makes it more difficult will give the criminals a huge advantage over the legitimate publishers, making regulation impossible.

The government is allowing crazy headlines out about this consultation and what they’re going to do. No doubt they’ll be consulting with child psychologists, women’s rights campaigns, children’s charities and a few suits from big business ISPs. Why don’t they consult the right people first – computer scientists. Ask the most important question:  “Is it possible?” Committees can spend as much time as they like navel-gazing on the moral and policy issues, but that’s not going to change anything if it can’t be implemented. It’s just going to make them look stupid.
