Ubuntu 14.04 LTS: Great changes, but sssh don't mention the...

Re: @Peter Gathercole Menus in windows @Vic and frank ly

Hmm. I'd not even considered that the window title has gone.

That may be a bit of a deal-breaker for me when I have multiple terminal/xterms on local and remote systems. Like you, I use the title to differentiate the windows from each other.

I still think that the biggest difference between those who can work with Unity and those who can't is whether they use multiple windows visible on the screen at the same time. Multiple overlapping windows - it's a struggle to use Unity. Single window or maximised whole screen application, it really does not matter too much. Actually, thinking about it, those who use whole-screen windows probably do not notice the difference with the placement of the window control buttons. It's always at the top-left of the window whether it is attached to the window, or at the top of the screen as far as they are concerned.

I use multiple overlapping windows, so you can see my preference.

Re: @AC, whatever. (was: whatever.) @AceRimmer

You have a point about Ubuntu being parasitic, but I believe that there may be more people committed to maintaining the Ubuntu repositories than there are the Debian ones. I think that it is a two-way thing, and Canonical pass any changes they make back into the Debian tree, so it is not as parasitic as it first appears. I'm not sure the same can be said of Mint.

I do mention LMDE (which I called Mint Debian) in my post. Check back at it to see why I have difficulty recommending it.

Re: Menus in windows @Vic and frank ly

There is a difference. Look at a normal Gnome or KDE system. Look where the maximise and minimise buttons are compared to the normal set of File, Edit etc.

They are on different bars.

What this release of Unity does is to put all of these on the same bar. So on the left, going from left-to-right, you've got the Unity Close, Minimise, Maximise buttons, and then on the same bar, you have File, Edit, View etc.

I'm sort of interested in how it does this. Normally, the menu bar is totally the responsibility of the application, and the window decorations are an encapsulating window or windows that enclose the whole application window, and also provides the resize bars around the window (that is one of the reason why you have a window border, to enable you to 'grab' the resize handles which are managed by the window manager). This is achieved using a parent/child relationship between all of the windows that allow a window closer to the root window to either grab and process events, or pass them into the application.

By combining the two bars, Unity appears to alter or even break the normal X11 way of doing things. I presume it is using the shape extension to try to dictate to the application a non-rectangular window. I am wondering whether there will be any unpleasant clashes between some old-style X11 applications and Unity somewhere down the line.

Re: @AC, whatever. (was: whatever.) @h4rm0ny

I used to feel this. When Unity appeared to be the 'way forward', I lost that feeling as Canonical appeared so dogmatic about it, but although I've tried, I cannot find another distribution that ticks all the boxes..

I though that Mint might be a possibility, but it feels too parasitic to be regarded as a distribution in it's own right. This is true of all of the Ubuntu derived distributions. They rely on Canonical being there to exist. Sure, they can fork the entire source and repository trees, but most of them are shoe-string operations that would not have the resource if they could not leech off of Canonical. I worked with Mint Debian, but the installation process and associated huge initial update (it's a rolling release, and the available installation media available is so old now that the update process downloads more than the original size of the installation) means that it is not suitable as a consumer distribution.

The same can be said about any of the Red Hat derived distributions. Indeed, I seem to remember a story about two years ago about Centos nearly winding themselves up because one of the critical maintainers dropped off of the radar.

Fedora is too fast moving, and RHEL has too many barriers put up by Red Hat for either to be considered to be consumer releases.

OpenSUSE appears to be a little media unfriendly, although does tick the box for support.

Slackware and Debian, being a long-established distributions are not going away and are totally usable, if a bit of a hair-shirt experience (especially Slackware), but are generally considered as too slow-moving and staid for a modern desktop distribution.

So I come back around to Ubuntu. Currently, rather than using Unity, I'm using a combination of Gnome Classic and Xfce (depending on the size of the system) on LTS releases for my own use, and do not have a current recommendation for people who ask me what they should use. I've listened to and welcome that Canonical have at least listened to at least some of the criticisms, and will evaluate 14.04 on my primary laptop with and without Unity sometime in the next few weeks.

Who knows, it may win me back. I'll try to keep an open mind.

Re: "Less so for organisations running Ubuntu on lots of PCs and moving to 14.04"

Group policy is one of the strongest advantages for Windows on the desktop. It is something that Linux distributions have not so far replicated (although I'm fairly certain that there have been attempts that have not gained enough traction to become generally accepted). Providing a configuration method like the registry that can be abstracted into a remote directory at the system level was a very clever move by Microsoft, although not their idea (LDAP, Kerberos and DNS were around before Active Directory became common).

But it always used to be that any changes you wanted to roll out system-wide on a UNIX-like system could be scripted and rolled out through some privileged remote execution method, something that UNIX-like operating systems excelled at (Kerberos came from UNIX-like systems). Coupled with the ability to completely segregate ordinary users from privileged users, this meant that you could roll out and configure UNIX-like desktop systems, and keep the configuration locked down and secure (at least from idle tampering). I have been doing this for 25 years or so, with UNIX and UNIX-like operating systems.

Nowadays, with so much of the Linux desktop and the associated infrastructure using things like XML configuration files, it is no longer an easy job to set some of these options. I've always had significant difficulty, and as a result a lot of scorn for XML configuration files. I know, it is possible to deploy parsers that can interpret and change these files from scripts, but it strikes me that this is very difficult if you do not have the schema for the options in the file.

I'm old-school, so can probably be laughed at by the younger generations, but I have tried to write my own parsers in shell and awk (still my tools of choice, because I absolutely know that they will be there on all but the most restricted UNIX-like system), and I just can't seem to do it. I know I'm not as sharp as I used to be, but it appears a non-trivial problem, even though XML is a well-defined language.

Coming across a new tool or desktop component, and not knowing or being able to find the available options, which may be missing from the XML file if the defaults apply, means that it is a hopeless task without much research. And all too often these oh-so-clever new tools, which work great, have not been documented in enough detail to enable you to script such changes. Sometimes, a tool comes with a CLI application to manipulate the settings, but you have to know what it is, and how to drive it. And the next tool along might have a completely different configuration tool. It's a nightmare.

Forgive me from ranting, but in this respect, I think that all Linux distributions have lost their way, and this is probably the flip-side of one of it's strength, choice.

Re: Sheer naked greed...

This is why they like putting additional material on the DVDs. Even though the original film may be out of copyright, the 'extras' being recently made, are not. So they feel they are justified in charging that amount.

Whereas I would like just the film. No extras, maybe some scene selections, and very little more.

Big Blue's GPFS: The tech's fantastic. Shame about the product

Peter Gathercole
Silver badge

GPFS is an old-school product. It's been around for a long time (I first heard about it as mmfs about 20 years ago), and as such it is configured like an old-school product.

But I would say that it seriously benefits from not being set up by a point-and-click GUI. It is a very high performance filesystem, and really benefits from the correct analysis of the expected workload to size and place the vdisks and stripe the filesystems accordingly. It's just one of those systems that is traditionally deployed in high-cost, high function environments where the administrators are used to/prefer to work using a CLI. If it were to appear in more places, it may need to change, but then that is what I thought SONAS was supposed to provide.

I have been working with GNR and the GPFS disk hospital for the last two years on a P7IH system, and now that the main bugs have been worked out (which were actually mostly in the control code for the P7IH Disk Enclosure which provide 384 disks in 4U of rack space, although it is a wide and deep rack), it really works quite well, although like everything else in GPFS, it's CLI based. But to my mind, that's not a problem. But it is very different, and takes a bit of getting used to, and it could be integrated with AIX's error logging system and device configuration a bit better.

Re: Was it a MITM or what?

This does seem very specific. For them to positively know that the data was leaked via Heartbleed, they would have had to log the out-bound packets, and I severely doubt that they have this level of logging enabled.

I also find the term 'removed' a bit strange, because to me, that means that they disappeared from the source. Maybe I'm being a bit too literal, but I find it strange.

Danes debut Bluetooth-connected 'made for iPhone' hearing aids

Re: What's new? @Dave 126

It is only a matter of time before the 'current' landfill Android phone will have Bluetooth LE. But you could get a Samsung S3 with android 4.3 for £200-300 and still be quids in.

The article was not emphasising the self-contained hearing-aid aspect of this device, but the remote microphone aspect. I agree that as a complete device offering the combined features may be desirable, but I said 'similar' behaviour', not 'the same'. But three grand for what is a digital hearing aid with Bluetooth and an app seems quite a lot.

What's new?

I actually fail to see what is new here. OK, the specific hearing aid is different from a bluetooth headset, and probably less intrusive, but the noise cancellation is part of many phones, and adjusting the tone balance to give maximum boost is just a high precision tone control or graphic equaliser.

I would have thought that it would be possible to get similar behaviour at a fraction of the cost using an app and a normal high quality bluetooth audio device designed for listening to music, rather than phone calls.

Of course, it would not function as a normal hearing aid without the phone, but at this cost, you could also buy a landfill android phone built specifically with a small screen and a large battery to be used all the time, and still be thousands better off.

Re: Like they care

Yes, I was rather lose in my description of the PIN being stored on the card. It's a complicated issue where the PIN is not actually stored, but a hash of the PIN and some information unique to the card is stored, so that the PIN you type in is hashed with the card-specific information, and is then compared with the stored hash to determine whether the PIN was correct. It's a one-way hashing process, so even if the information on the card could be read, the PIN cannot easily be determined.

But the point is that it is completely on the card (as is the cryptographic processor that computes the hash - I'll bet you did not know that your bank card had a processor on-board). This is how the calculator-type authentication devices can work in isolation from any data connection, as all the authentication device is doing is providing the PIN to the card, and initiating the hash/compare.

It should not be the case that the card-issuing authority should know the PIN, because that breaks the personal secret that the bank claims tie a transaction down to you, and as a result absolves them of any responsibility for card-fraud.

In the UK, all bank issued cards, whether credit, debit or charge cards use the same mechanism for chip-and-pin, although it is different from other countries. Your point about the magnetic stripe is interesting, because UK cards do actually still have mag-stripes, so that they can be used abroad.

That does suggest that the card issuer does have to know the PIN.

I'm not sure that the 360/168 was a real model. The Wikipedia article does not think so either.

As far as I recall, the only /168 model was the 370/168, one of which was at Newcastle University in the UK, serving other Universities in the north-east of the UK, including Durham (where I was) and Edinburgh.

They also still had a 360/65, and one of the exercises we had to do was write some JCL in OS/360. The 370 ran MTS rather than an IBM OS.

The cloud awaits... but is your enterprise ready for the jump?

Re: The dinosaurs live

OK. 2e2 were an outsourcer, but it is not the viability of the provider nor the moving of the service that I was mainly commenting on, it is the copies of the data that will be out of your control that I was trying to indicate.

2e2 were an example. It is unlikely that Amazon or Microsoft would go out of business, but could IBM choose to ditch their cloud services in five years time if it does not return the projected revenue, or some of the smaller players decide that the margins are just too slim?

It always puzzles me how you keep any dynamic application that is hosted by two separate cloud providers in sync with each other. Do you pay to have dedicated bandwidth between the suppliers with some geographical lock in? Do you have explicit cables laid between them? Virtual circuits or VPNs through established teleco infrastructure or the Internet? Or do you run it as a distributed application with both installations processing data.

All these questions can be answered, I'm sure, but how many people really think things through to this depth before deciding to go down the cloud route. I'm sure that there are customers who are already there who are considering their DR strategy for a cloud provider failure with some trepidation.

Whilst I don't mind being called a bit of a dinosaur, I have lived through the Mainframe->VAX/UNIX->Windows/Linux transitions that have happened, and what this has taught me is that the latest cool-aid that is being served up by the marketing boys is never as simple or cost effective as the projections. Let's just call it the result of experience!

Security

I take on board everything you say about the security of the data centre.

But the difference is that if you host your applications in your own data centre, the security is entirely within your control. How good you make it is up to you.

If it is in a service providers, you trust that their security is as good as they say and as good as your contract with them. It's that same trust question that you sensibly query when it comes to availability.

Similarly, you trust that the barriers they construct between your service and all of the other services running in the data centre, and you trust that they will not move the data/service outside of the region you've specified. It's almost certainly good enough, but if that trust breaks down, what is the comeback you've got from the provider. Check the penalty clauses in the contract.

You've also missed out a vital question. What happens if the service provider has a state change, if they get bought, or, heaven forbid, fold (like 2e2). You need to consider where and how to move your service and all it's data, and also whether there is a residual risk in your data being left in various stages of protection on equipment that includes the backup solution that may be bought in toto, or appear on the broker market.

Encryption may seem like an obvious solution, but if your service actually processes data rather than just serves it out, there will be the means to decrypt the data present on the systems that you may no longer have any control over.

Re: "Windows XP is a thirteen year old operating system .."

The worrying thing is that the issues they are patching now may have been in Windows for over a decade. We just don't know how long some of these vulnerabilities have been exploited without us having been told about them.

We remained happy in blissful ignorance of the problems, even though they could have been exploited. And how many more are there that are either currently unknown, or are known about but not published?

I am expecting Security Essentials for XP, which has had it's life extended for a while more, to start issuing dire warnings about every little thing it finds, just to increase the fear and uncertainty amongst the remaining XP users, to encourage them to change.

I am not planning to change my Wife's XP system that sits behind the house firewall, as long as she keeps using and updating Firefox and Libre Office. She does little else on the system (not even email), so I am pretty sure that she is unlikely to be affected by new vulnerabilities, and has nothing of any real value on the system even if it does get compromised. Must remind her to keep it backed up, however.

Driver drama delays deep desert XP upgrade

Peter Gathercole
Silver badge

Re: Windows 7 upgrade advisor anyone?

One thing that constantly annoys me is that with windows, there does not appear to be anything like a generic driver for a particular device's chipset.

With Linux, as long as the identifier ID's are listed against the correct generic driver, there is a great chance that it will work. You end up with about a dozen drivers installed that will cope with 95% of all devices available.

With Windows, even though you may have a driver for the same chipset as that on the card you've got, you can't make it work without the specific driver from the card's manufacturer.

This was brought home to me years ago with Belkin CardBus WiFi devices, where v1, v2 and v2.1 versions of a particular numbered model of WiFi card needed different drivers, and it was very difficult identify at the time which driver was needed, because they were not well labelled (why could they not just change the model number?).

Putting any of the devices into my Linux instance on the same machine worked immediately, without further action.

Re: " toughest substance in the known universe"

The early Lego bricks were almost exclusively just red and white, no yellow, black or grey. The bases were a cream colour, and instead of a circle pattern to lock the 'knobs' of the bricks in, used to have square holes in the bottom that the 'knobs' would fit in. Additionally, the 2x1, 6x1 and 10x1 narrow bricks would not have pins to help hold them on, but had cross-wise narrow divisions to help keep the sides in enough to grab the knobs of the lower bricks. It did not work as well, and often a complex model would be difficult to build because it just would not lock together.

The plastic of Lego from 50 years ago is different to modern bricks, and I think it was a styrene based plastic, and a bit brittle (yes, I am talking real Lego here, not the Betta Bilda and like copies, which we also had). Consequently, it would break on occasion. My older brother and I used to build models, and then use the spring powered suction dart guns (with the suckers removed - never be allowed these days) to 'blow' the models up, in scenes reminiscent of Stingray and Thunderbirds. Every now and then, we would break a brick. (Side note. In the film Thunderbirds Are Go, some of the houses that Zero-X crashes into are clearly made from Lego if you frame step the DVD!)

There used to be completely different windows and doors, with glazing in as well. I remember the garage bases with up-and-over doors, which were the right size to allow you to build a garage for a Matchbox sized car. The garage door auto-opened (it was weighted) and was held down by a flap that caught the bottom of the door. 'Drive' a car up, and over the flap to press it down, and the door would open. Push the car in, and close the door, and then trigger the door, and the car would roll out because it parked on a shallow ramp that formed the base of the garage.

Originally, the roof bricks were steep, almost 45 degrees so that a 2x4 roof brick had 1x4 knobs on the top to allow you to build the roof.

There also were wheel bricks, with wheels with rubber tyres (originally white/beige, but replaced quite quickly with black tyres) that had metal pins that would push into the wheel brick. If you stood on on one of the wheels which was pin-up, you really know about that! This was extended to train tracks and special flanged wheels (we originally used the wheels with the tyres taken off), complete with electric motors.

Things started getting different in about 1968, with different plastic, curved bricks, and specialist fence, trees, flowers and less steeply raked roof bricks, with additional colours and clear bricks, different plastic, and more brick sizes. And then they introduced models with special parts made only for a particular model, which would always go missing. People started building the models and leaving them built, rather than using their own imagination.

My youngest son, who is 18, has his complete lifetime's worth of bricks from special models (he's a real Lego fiend). We've just done a tidy and consolidation, and we have many thousands of bricks, filling all the drawers of a desk, along with storage tubs of the more common bricks, and glass coffee jars for the more specialist bricks. I don't reckon he could make any of the models up now, but he has vowed to find all the bits for the X-Wing kit he had! We may have to go to the Lego site and order a piece or two (yes, they sell single bricks from almost everything they've done in the last 20 years, but they tend to be expensive). They will even print on bricks (particularly body parts) from your own design if you are prepared to pay for it!

And I'm about to take ownership of the remains of my Lego set from the 60's from my father.

Microsoft: Let's be clear, WE won't read your email – but the cops will

Peter Gathercole
Silver badge

@Paul S. Gazo

I don't think you've followed the story.

I totally agree that Microsoft have the right to scan their employee's work provided mail account.

But that does not appear to be what they did. They scanned one or more of their customer's mailboxes, and used that to identify which employee was the culprit, and then provided that information to the police. So it appears Microsoft provided the private mail of one of their customers to the law enforcement agency without a warrant. Now, it's not clear whether the mail provided to the police was the mail from the customer's inbox, from the outbound mail transmission log, or the employee's outbox. You would have to look at the headers on the mail the police were given to be sure. If it was from the outbox or the transmission log, then that is within Microsoft's internal domain. If it comes from the customer's inbox, then it is not, even if it is hosted on a Microsoft mail server.

I agree that you would be stupid to expect that mail travelling through any part of the Internet is particularly safe from prying eyes unless you encrypt it, but you would not expect the mail host to use your (as a customer's) mailbox to as evidence against either you or someone else without the correct legal authorization.

Reading between the lines, the article suggests that Microsoft may have scanned many of their customers in order to identify who had received the mail. Without a warrant, that may be illegal, but difficult to prove, because an mail service provider must have the right to read their mail server's contents, at least for backup purposes. How different is that to grepping (I know, it's Microsoft, but grep means more than just saying find) a phrase from the mailboxes. Not really any different at all. It's not like anybody is reading and comprehending the mail.

So nothing that's happened is definitely illegal, but some of it is definitely questionable.

Hot, young under-25s: Lonely slab strokers who shun TV

Peter Gathercole

Format important

I think that the format of the media is also a factor.

Unless you have a computer, tablet or phone with an HDMI port (or you have some expensive Smart TV or STB), you are unlikely to watch digitally delivered media on the large screen in the living room. You will watch it on another device, because it's easier. I also find this is the case for personally ripped media.

That is until you get a device that sits in the living room, receives digital media, and can play it on the big screen. When that happens, you move back to the TV (as long as you have control of it).

I can plug my phone and my tablet into the living room TV, and it is more useful than you might think, extending what you use the TV for. I also use Sky On Demand, and a number of internet capable devices like BluRay players and consoles in various places around the house, attached to different TVs. If I can use the TV, I will.

I will be interesting interesting to see whether Roku and similar devices catch on before people start replacing their current TVs.

Re: Prison time is required @AC

That's just silly. I hope it was meant as a tongue-in-cheek remark.

If you fine them (personally) mega-millions (even if the law allows this), they will just declare themselves (personally) bankrupt, It also makes the fines largely meaningless if they are in prison for 20 years. By the time they get out of prison, they will be a discharged bankrupt, with the fines written-off. Grab their assets, OK (bankruptcy laws already allow this) , but they probably won't actually have very much to grab. I don't think Michael Robertson was another Kim Schmitz.

By the time they come out of prison, they will not be worth anything much at all anyway, so there is no point in trying to recover any money from them, especially as their skill set will be so dated that they will probably not be able to set up any high revenue service.

And you think that the prison sentence should be more than that for assault or homicide? I would put the sentence for anything that resulted in a person being physically harmed as much higher than just a financial loss.

Don't believe the music industry's assessment of what they have lost. In reality, it's a fraction of what they claim, but the US court system allows them to assess the loss as a certain amount per track, and then add punitive damages. In reality, a streamed-play of a track will not equate to a lost sale, which is what they claim. Most freeloaders will not go and buy a track if they can't stream/download it, they will just move on to something that they can.

Re: Network goes titsup? Really?

I lost all access to the 3G and 2G EE networks on my phone in West Somerset (there is no 4G service there), which is on a 4GEE plan. Strangely, my old Palm Treo with an Orange prepay sim in it connected to the 2G network without problems.

Repeated attempts to register the phone on any of the 4 EE networks visible there failed.

From this information, I think it must have been a problem with the access keys or identity for 4G enabled SIM cards, because my 4G phone could see the network, but could not connect to it.

It was working OK at 06:30 this morning when I checked.

If you are wondering why I have a 4G plan in an area without 4G coverage, I got this phone call from EE offering me an upgrade at a significant discount if I switched from my 3G Orange plan to a 4G EE one. Saved me about £5 per month (on a £25 contract!), and gives me more data and texts. Would be better if it worked, though (they screwed up the port between the networks as well).

I think the upgrade offer had something to do with them trying to build up their customer base to claim they are the largest 4G network.

Re: Obvious Star Wars reference

Teaching physical tactics to a kid like Ender is easy, especially if there are unpleasant physical consequences. If you read the book, it's clear that there is a natural progression from simple Battle Room scenarios to the simulator to actually fighting the Buggers, and Ender did not know then the transition between the last two happened.

Trying to teach kids what cyber security is without some natural, easily observable cause and effect is a hiding to nothing.

Maybe the politicians have watched a film like The Matrix, and think it's a case of putting on some VR kit, and performing cyber-kung-fu in a virtual world!

What is it about these backward graphs!

Is there something I'm missing?

If I have time on the X-axis, I always make it ascend left-to-right. This is the second time I've noticed that El Reg. has published an article with a graph with the X-axis ascending right-to-left. Is this some kind of marketing chart that I'm not aware of, or is Chris just seeing whether we're on our toes?

Re: Self-powering? @SuperTim

I think it's a closed system. Apply power, and you go to hydrogen and oxygen, with a corresponding increase in volume. Remove power, and it spontaneously forms H2O, with a reduction in volume. Switch the power rapidly, and you get a vibration.

Nothing is consumed except electrical power.

Re: Self-powering?

I think it's important because it's a new way of converting electrical energy into physical work at a nano scale.

Currently we use electric motors, voice coils (and other electro-magnetic devices), piezoelectric crystals or direct thermal expansion to convert electrical energy into movement. This seems a new way of doing the same, and if it does it more efficiently, or at a scale not previously possible, then it is important.

Re: Damned if they do, damned if they don't. @Joe 48

By contrasting identity theft with wholesale surveillance, you are confusing the argument. I, too would like a world where identity theft is prevented. But this won't happen by the government watching what everybody does.

Having concentrated data is more likely to cause identity theft if the information that is kept by GCHQ/NSA ever leaks. Imagine what damage could be done if in one information dump, miscreants get health records, bank details, loan information, social security data, work history, email trails, especially if this data contains access credentials to all of your on-line systems gathered through state-sponsored data gathering and cracking of the very cryptography systems that people believe keeps them safe on-line.

After all, we all know how good governments are at keeping such data safe!

I may come across a bit paranoid here, but it is probable unsafe to be too complacent.

BTW. Honesty is not enough to get/maintain SC clearance. If your honestly reveals the fact that there are serious concerns about you having a blackmail vector (serious debts, family members working in unstable areas of the world etc), or even if it shows that you've been out of the country for extended periods, then you will get SC clearance denied. I've seen it happen, and the first time I applied, the clearance was seriously delayed because I gave as a personal reference an upstanding professional member of the community who happened to have been born in Kenya during the Empire days (I did not think that it mattered - turns out it did).

And who knows how the rules may change in the future. It would be perfectly possible for those in control to make smoking dope in your history an automatic fail. It probably won't happen, but we cannot be sure.

Re: Damned if they do, damned if they don't. @Joe

You may not mind now, but you might in years to come when the data, whatever it is, is used against you in ways that you cannot imagine.

Nobody is squeaky-clean. Everybody does something at some point or other that is marginally illegal (speeding, stopping in a no-parking zone, littering, jay-walking, visiting unusual web-sites etc), or anti-social, If there is a record of it, no matter how trivial it may be, it could be used against you to build a case for further investigation if you suddenly do look interesting.

I presume that you know for a fact that your Nan has never been involved in any protests or pensioner activist movements, or a member of the Communist party or UKIP, or was an unused Russian sleeper agent, or even someone who worked at Bletchley Park and is not allowed to talk about it that may warrant investigation (wild speculation, I know, but are you sure).

The only way to prevent this is to stop the data collection in the first place!

Re: Minty and PAE @Bullard

Hmmm. You're right. It can be done just using grub. Install both kernels, and then set the default boot to be the one you want. Trivial really if you think about it.

Shame there's no nonPAE kernel in the repos. any more!

Re: Minty and PAE @Bullard

I'm not suggesting that the default installation disks ship with a default non-PAE kernel. I like your idea of making it a boot option, but the kernel would then have to have both the PAE and non-PAE code compiled in. I don't think it's written this way. It's a conditional compile time option.

But the real problem is that if the kernel that boots off the media to install the system is a PAE kernel, you cannot even start the install process on a system that does not flag PAE as an option.

It would be possible to make it an install-time option. Boot using a non-PAE kernel, and install a PAE kernel during the installation, although the kludged version of Grub or whatever it is that used by the no-PAE install process that is on one of the support threads does give an alternative, although whether this really works on a processor without PAE at all, rather than one that just lies about not having it is debatable.

Where I really do have a problem with Canonical is that post 12.04, there is no non-PAE kernel in the repositories. This seriously complicates the process of putting together a modified boot image (as was done with the alternate Xubuntu 12.04 install disk) to give you a chance to install it on older hardware.

If you really don't have a PAE capable processor (like a Banias Pentium M in a Thinkpad T40, 41 or 42), then to install any *buntu post 12.04 it will be necessary to find a PAE capable host system you can install, pick-up the kernel sources, compile them, and then insert the resultant kernel into some distribution medium to allow you to install your Thinkpad (other packaging methods are available).

This is not going to be suitable for your average Joe User. It would have been minimal work, and not a lot of maintenance, for one Canonical employee to maintain a non-PAE kernel, and package an alternate install image to put on their site, like they used to. My view is that Canonical want to leave behind their Linux legacy to a world where they ship the Unity OS, that may still be based on some form of Linux, a bit like OSX is built on some form of BSD.

Me, I'm looking at buying a cheap T43 with a Dothan processor or maybe a T60 to replace my T30 which finally died at Christmas. ThinkWiki says that this should have PAE.

Re: Minty and PAE

I must admit that I was really annoyed about the requirement for PAE on most modern Linux distributions, because even though PAE has been a feature on a majority of Intel processors since the Pentium Pro (IIRC), there are particular more modern processors, especially the Pentium-M, Celeron and early Atom processors that either do not have PAE, or do not flag it in the way that the boot/kernel checks work.

This is very annoying for people who have laptops of the generation just before the Core processors came along, which include a whole raft of perfectly capable HP and IBM systems, and those with first and second generation netbooks. These are precisely the type of system that Linux should be able to life-extend.

So why is PAE required? Well, it's not in order to support more than 3GB of memory, because it is not necessary to have over 3GB for general work on most Linux distributions (I had Precise working fine in 1GB of memory on my Thinkpad T30 before it finally gave up the ghost, and I currently have Xubuntu 12.04 working on a 512MB eeePC 701).

The problem is that the NX bit, which allows pages to be flagged so that the processor cannot execute code in the page (a useful security protection against things like stack-smashing attacks amongst others) is bound up with PAE. If you want NX, you have to have PAE turned on, and the more recent Linux kernels default build requires NX.

It's not really a restriction by the distro maintainers, it goes all the way back to the Kernel development team. It is still possible to build a kernel without NX and PAE, but it is necessary to have such a kernel on the distribution media in order to build a system, and most distros have a PAE kernel by default, and now are even removing the non-PAE kernel packages from their repositories.

This has taken the edge off my anger about PAE being necessary, but it does effectively mean that many people with 6-8 year old laptops or netbooks will seriously struggle to get a modern Linux working, and will result in a generation of perfectly usable laptops ending up in recycling.

Mind you I am getting really tired of the distro forums containing comments like "why are you using such old kit - buy something new" when the commenters do not really understand the problem.

Re: idiot bosses @horsham

There are financial reasons why large companies, particularly ones with shareholders, will have a large number of contract staff complementing their permies.

The primary one is that contract staff appear on a different cost stream, and are seen as a cost against revenue, rather than a resource/capital cost. This looks good on the end of year financial report, because the company has to make provision to write down resource costs (things like pensions payments, provision for statutory redundancy payments, sick pay and employer insurance etc.) for permanent employees, but not for contract staff. This makes the shareholders happy because it reduces the money that has to be tied up and simplifies the books.

Companies can also start and stop projects very quickly if it is staffed by contractors.

Why can’t I walk past Maplin without buying stuff I don’t need?

Peter Gathercole
Silver badge

Re: 90s ???

How can you compare '70s Maplin to Tandy?

Maplin actually sold the components you wanted, and also put together the kits of parts from the ETI projects to save you having to order them seperately yourself. And the catalogue was as good as a reference book when it came to the pin-outs for transistors and that 74LS105 and 4114 static memory that you were soldering on to the project you were making out of Vero-board.

If you went in to Tandy, all that you came out with was a realization that they were not really an electronics store. You only used Tandy when they had the week long cumulative 10% discount per day sales that they needed to have in order to clear the stuff they could not sell full price, or you were so desperate for a component that you would risk disappointment because they did not have what you needed.

And for the people who mention Radio Spares and Farnell, at that time you had to have a trade account before they would even send you a catalogue, let alone sell something to you! For the hobbiest, Watford Electronics were the only real mail-order alternative, although they did run from a shop on Watford High Street which was a real blast to visit because of all the miscellaneous useful junk they had there.

Unfortunately, Maplin today are a shadow of what they used to be. If you want specific components (last time I wanted a set of capacitors to repair the power supply in an out-of-warranty Sky HD box - yes a Thompson one) they did not have all of the values I needed, so I had to go somewhere else. All they appear to have now are the component grab-bags, a small number of kits, many dating back to the ETI days, some tools and various gadgets you can buy cheaper elsewhere.

Re: @Evil Auditor

This is for the UK.

- Age of consent and marriage with parents agreement, 16.

- Age at which you are legally allowed to drink, 18 (although there are variations in venues like restaurants where you can drink wine as long as it is served with a meal from a younger age).

And another age related restriction

- Age at which you are allowed to drive, 17 (unless you are a sole carer for a family member, where you can drive at 16).

So you can get married but not be allowed to drive to the Wedding or participate in the Champagne Toast.

Hmm. Things CSVs don't work very well for:

Strings with spaces in

Strings with commas in

Quote characters around or within strings to allow embedded spaces and commas

Embedded quote characters inside quoted strings

Embedded new lines in quoted strings.

These are all things that MS's CSV files contain, and they make reading the file more than a little difficult, as the rules that are used do not appear to be documented.

I know! We need to write a standard for it!

Re: Let's hope this actually filters through @Refined

You are reasonably lucky. When agencies first started keyword-scraping from CV's in the 90s, I found myself being offered IMS and MVS roles.

And the reason? I had Amdahl listed on my CV.

Yes. Amdahl mainframes, but running UTS and AT&T R&D UNIX. Not a scrap of any IBM operating systems. Destroyed any trust I might have had in the recruitment sector at the time, although I think the best have improved a bit.

Re: Cant we just bring back EDI? @Primus Secundus Tertius Re: EDT

You've actually inadvertently stirred a memory here.

I used to use DEC RSX/11M version 3.2. The supplied editor on that pre-dated EDT, and was called EDI, and was a line editor. If I remember, it was very difficult to use (even though I was a frequent UNIX ed user at the time so I was used to using line editors). Fortunately, due to good binary compatibility, we were able to completely ignore it, because someone sent us EDT binaries from either a RSTS/E or an IAS or RSX/11D installation that worked well enough.
