So you are saying that the physics of aerodynamic flight is not natural?
If you ignore the lack of a vertical tail fin, the configuration looks uncannily like Zero X, or maybe a little like Fireball XL5.
Were the model designers at APF prescient, or knowledgeable beyond their time, or is there some plagiarism involved. Or maybe there is just a natural way of doing these things.
Just put a boundary network device with a sniffer, something like a Linux firewall. Allows you to record all IP traffic flowing through it using something like tcpdump. Doesn't need any antenna.
I kept reminding my kids that I could, if I wanted, see the URL of all web pages they visited and a lot of their other traffic over the household LAN (can't do much about 3G, but that's another story). Made them much more 'net aware. I know that they could obscure the data using encryption or a VPN, but this would actually achieve part of what I want them to do, and that is to understand what it is to be on-line safely.
For the record, although a lot of the URL and connection data the data is kept on the Firewall for months, I've never felt it necessary to snoop on them (although I have used the data to prove I could, and also to resolve bandwidth contention between them). It's amazing what being open about what you could do can achieve, without actually doing it.
My 'phones all filter down to the kids as I upgrade the phones, although I gave each of the kids their first phone at whatever age they started spending significant non-school time out of the house, normally early-mid teens. First phone always low end, low value phones, often hand-me-downs on PAYG to give them a means of calling-home, never as a means of keeping tabs on them.
Currently my daughter is waiting for me to replace my Sony Xperia Neo so she can have it, and her Samsung Galaxy (one of the low end ones which was my first Android phone) will then go down to my youngest son, which will replace his Nokia clamshell. This will mean that everybody in the household except my wife will have smartphones, and she just doesn't want a mobile at all.
Eventually, the low end phones just end up sitting in a drawer as 'spares' (like my old Nokia 7110, now really only kept as a curio). The exception is my Palm Treo 650, which I am keeping as my active spare (with a PAYG SIM in it), because its not that desirable to anybody who was not a Palm user, and I like it too much.
The only real thing that bugs me is how soon service provider locked Android phones stop being updated by the service providers. My oldest son noticed this, and as a result always buys SIM-free phones (he's old enough to have his own money to spend) that get the updates direct from the phone manufacturer or Google, not waiting so see whether the service provider is prepared to package the updates. Maybe SPs should be forced to admit that they will never update old phones, and allow them to be un-branded so stock ROMs can be installed on the phones without hacking them.
Maybe I have a pedantic mind, but when I read Monty's comment, I immediately thought US protectionism, and had to read it carefully in order to get any other meaning. So, no, I don't think it was obvious what he meant, let alone what he implied.
The full context in the original comment is "and this could have been a real kick in the nuts for Apple that possibly could have costs jobs and affected real people"
There is an implication here that the subject of the potential kick would be Apple, and by association, that the jobs and real people that would be affected would similarly be associated with Apple. I agree that this could be the S. Korean and Chinese workers, but bearing in mind that any displacement of product would probably have meant that another brand made in South East Asia would have benefited, possibly more than if the Apple product was sold. So maybe a blow to some workers, but a benefit to others.
I don't feel at all guilty not worrying about US jobs at the moment, as I believe that most US based multinationals are currently screwing over their non-US subsidiaries for jobs and profit, and I'm not in the US.
Is the implication in your statement "affected real people" mean that Samsung employees in S. Korea or even China don't count as "real people"?
...tend to be informed and technoliterate.
Older members of my extended family still watch mostly the first 5 channels of Freeview, because that is what they know, and they know where they are with "1", "2", "3", "4", and "5" on the remote. Channels under 10 do have a real premium when it comes to people who are used to press just one button per channel.
I've tried and tried to make them more aware of the +1 variants of ITV and Channel 5, to no avail. I just have to assume that they are too set in their ways to change, or maybe that they cannot read the programme guide on the screen!
It's a while since I did any education on the power factor, but it is quite clear from the reading I've been doing over the last few weeks that the whole power factor issue is much more complex now that it used to be.
Back in the days of inductive loads, the power factor was mainly due to a phase shift caused by the load (and in fact, devices that use significant amounts of power nowadays have to have additional components to bring the power factor down to close to zero before they can get a CE mark in Europe).
But since such simple times, the increased use of switched-mode power supplies, used because they are much smaller and more efficient, has lead to the waveform of the neutral being not only phase-shifted, but corrupted so that it is no longer anything resembling a sine wave. I still cannot get my head around what is needed to work out the real power use in this case. I'm sure it is all factored in, but without further research, it's beyond me.
All I know is that the two clamp-on power meters I have rarely agree on how much power is being used in the house, but they still are a good indicator of when the consumption goes up and down.
Fortunately, the smart meter will not be able to power individual appliances down until either smart sockets are installed, or the appliances start implementing remote control. Both features are in the pipeline, but not generally here yet.
As I understand it, when you do get remote control from the meter, you will be able to assign certain devices (like fridges or freezers) a higher priority, so that other devices will be powered down first.
The savings I would get would be minimal, because I am already using a power consumption monitor on the house as a whole, and a plug in consumption meter to measure the power of individual devices.
"Never underestimate the bandwidth of a truck full of tapes".
Over the net is fine as far as it goes, but it does not have to be the only mechanism used. That's why most large datacentres use tape with offsite storage pools for their DR plan.
The CentOS version problem and not storing the VM definitions in both sites should not have happened, but I would not bash yourself over the head wrt the sendmail config.
Sometimes it is not enough to do a restoration test. For some services, it's necessary to actually run for a period of time in your alternate location. I suspect that any number of 99% tested DR plans may hold something like your sendmail problem.
This is normally because of the high cost of a full DR test. As a result, 5 minutes after the last DR test has been concluded sucessfully, an apparently minor change somewhere in the depths of the environment may invalidate it!
Of course, if you do run from your alternate location for enough time to make sure that you've got most of the bugs, it introduces another problem, that of fail-back. This is something that many, many administrators just do not think about. If you run from your alternate location for any length of time (to rattle any connectivity problems out), you have to have a procedure to revert back to your primary site. And it's not always a reverse of the DR plans, because these are often asymmetric.
The background to this is that most businesses don't think beyond restoring the service. One bank I worked for acknowledged (or at least their DR architect did) that it would be almost impossible to revert back to the primary site if they invoked their full site disaster plan for their main data centre. The services would be back up, but vulnerable to another failure.
Is this because they stuff everything else they keep in their pockets into the one they don't put the iPhone in, just so that they doesn't scratch or mark the phone?
I read the first sentence, and was preparing to flame, until I realised that you were being ironic!
You may log on to a system, but there is a HUGE difference between a system and the network, and I say again that if you do not understand the difference, you should not be commenting on stories like this.
You really don't log in to a home network, not unless you have implemented domain level accounts and an authentication server, in which case you are really logging into the domain. I strongly suspect that you haven't, although I do admit the possibility.
On all Windows systems I've administered outside a company environment, the network settings are set up on a per system basis, not a per account basis. This means that once logged in to a system with any account, all network access is the same. And it is normally not possible for a web site to know what user account is in use on a particular PC (that's why they go to so much trouble putting cookies in your cache, so they can track who wou are). So to the ISPs web site that the popup comes from, there is no way of knowing whether the account is Tarquin's or Dad's. That level of information is just not available to the web site.
What the ISPs may end up doing is directing you to a site where you have to log in to the web site, using an account that was set up when the account was set up. This would do what they need, but would render the entire home network unusable until the account owner was available. And I suspect that many users (like me) do not use that account, so may not remember the user id and password for that site.
I suspect that I have been locking down my Windows PCs so that most users are not using Admin for longer than you. My background is 30+ years of administering UNIX systems, so privilege separation is engrained in my psyche, and I learned how to do it for my PCs (together with a mechanism of relaxing it for those STUPID programs that need admin rights) almost as soon as I got an NT based system in the house, which was after I started putting Linux on all my PCs.
I was not advocating it. I was just suggesting it as an alternative to DPI or a simple DNS lookup which are either too complex or too naive to be considered.
And as I said, I am not claiming to be any wizard, although I do believe I have a working knowledge of DNS and IP. I'm sure that the ISPs will do something much more complex.
I understand about shared servers serving many sites. I must admit that I had not fully considered this while drinking my tea, but were I really designing this, I would have spotted it, I'm fairly certain. But the majority of most site visits are probably to servers that do not serve more than one service, (Google, Facebook, YouTube, Ebay, Twitter, the TV channels), or if they do, the sites are closely related, so it would work for a sizeable proportion of users.
Anyway, my point was that it does not have to be DPI, and in fact DPI is probably exactly the wrong way of trying to block porn, as you would have to assemble a complete picture or frame of a video, and then subject it to image analysis to try to determine what the image was. This is clearly more than the ISPs will be prepared to do.
It does not have to be DPI. all they have to do is reverse lookup the IP addresses of the initial TCP session setup packets, then see whether the name or domain is on the blacklist. For UDP services (which do not include web browsing) you may need to look up every packet.
And if the lookup does not return a FQDN at all, then they block anyway it as a precaution. It could be a dark network!
This gets around all of the alternate DNS workarounds, but would not stop proxies via systems that are not blacklisted.
I've thought this up over a cup of tea. I'm sure that people much better than I can think of even better ways of implementing this!
Your post makes no sense. Individual users on a normal shared home network do not 'log on' to the network (even security concious people such as I do not operate a RADIUS server at home). ADSL connections are almost always-on, logged in using stored credentials in the ADSL router, and individual machines just connect to the network (using a pre-shared key), get a DHCP address (if this is how they are configured), and off they go. Your post shows a remarkable lack of understanding.
What was being said on the radio this morning was that the first time a user from a household connects after the control is turned on, they will be presented with the pop-up which would prevent further web access until the level of filtering had been selected. The way I understood it was that it would be from whatever device attempts to access the web first. This could be from one of the kids computers, logged in as their own account on the system.
In this day and age, people do not share a single computer. I have (believe it or not) more than 30 devices in the house that can connect to the network and browse the net (computers, laptops, phones, tablets and consoles), and on a regular basis, I would expect to see at least 15 connect on a daily basis (7 active computer users in the house, each with more than one device).
It is possible that it could be made per-device, but that would need something like cookies, and would thus only affect browser traffic. But this would not work, because I regularly clear out the cookies on my systems, and would also mean that the kid's computers would be allowed to set their own policy.
In my case it is mostly academic. The youngest member of my household is 17, so strictly speaking does currently count as a child, but they will be 18 when it is likely that these controls kick in. But a household with a scattering of laptops and tablets, often the kids will have their own devices, and could see the request to set the filtering first.
I was listening about the 'pop-up' or 'splash screen' that would come up on Radio 4 this morning on the way to work.
Neither of the people interviewed who were supporting it said anything about how they were going to make sure that it was the account holder who clicked 'allow'. What if the kids saw it first?
I like my internet to be unfiltered, and I would love to see how the ISPs are intending to implement this. I suspect DNS filter, reverse IP lookup and subsequent DNS filter in a content filter in the ISP (gets around using alternate DNS servers), and direct blocking of specific known IP addresses. Extend this to IP addresses that do not reverse resolve (just to be on the safe side), and it would be possible to do what is being talked about.
But all of this is very intrusive, and will probably rely on blacklists in order to work. And it will have to be stateful in order to be remotely efficient. This means that over and above what the ISPs already keep, there will be mine-able information, and also there will be the ability to control what the country sees by controlling the blacklist.
If you can't differentiate between the OS and an application that runs on the OS (the forum software), then I suggest that you go and do some education.
Any application that runs it's own authentication mechanism, regardless of the OS it runs on, has the same degree of vulnerability.
I have an account on that site, but is it using the lowest grade of password that I use, so any site that may share the same password is probably not going to have any serious consequences to me.
That may have been how it was designed, but that does not mean that it the way it now works.
The current Internet had a number of very serious pinch-points, where disruption would not necessarily damage total connectivity, but would cripple performance. Certain organisations and particular buildings around the world are regarded as hubs, and have a disproportionate amount of the connectivity for a region, country or for international traffic.
But that is not what this article is about. If you are a stock or futures trader, and either your systems or the systems that you need to talk to on t'internet are DDoSd, then you may be unable to trade. If this happens, and the news leaks, then your share price may take a tumble, and you may also end up losing company value as well as revenue. Ditto any company that relies on connectivity to trade or operate, and there are a large number of those.
I though there were cars that pretty much did this already.
Generally completely agree with you.
But there are situation where it is useful, and also where it is essential.
It's useful to allow two different operating systems run on the same hardware. Back in the late 1970s, the University I was at turned of their IBM 360/65 running OS/360, and migrated the workload onto a proto-VM on their 370/168. Normally the 370 was running MTS (look it up), but by using a VM, it could also do the legacy OS/360 work at the same time.
Currently, you might do the same to run Windows next to Linux on the same system.
In addition, many enterprise OSs running today were initially designed more than a couple of decades ago. Back then, 2 CPUs in a system was novel outside of the Mainframe world, so the same OS facing a machine with 1024 CPUs may struggle. OK, the OS should have been updated, but when these OSs were written, people probably did not foresee such large systems (640KB anybody), and built in serious limitations that require a lot of work to overcome. Unfortunately, these OSs are often becoming legacy for the vendors, so it seems unlikely that the necessary work to overcome the limitations will be done. So often, it makes sense to divide up your workload into separate OS instances, and stick each into it's own VM.
They can knobble this as well. All they have to do is block TCP and UDP to port 53 on any systems other than their DNS servers in either the router they supply to you, or within their infrastructure.
Would be hugely unpopular with most of the readers of this site, but would make no difference to the majority of their customers.
I have no knowledge of Netware myself, but if you are talking X11, then it's UNIX, not Linux. Linux had X11 servers and clients (of course), but X11's home was UNIX (and to an extent, some proprietary OS's like VMS).
If it was X11, then what it gave you was the ability to run the GUI administration client programs remotely on any workstation with an X11 server (if you are unfamiliar with it, the server controlled the screen, keyboard and mouse, and programs that attached to this X11 server were clients, wherever they ran), meaning that you would have the ability to remotely administer the Netware server, long before RDP, VNC, or Citrix were on the scene.
X11 servers were available for UNIX and Linux workstations, OS/2 and even Windows NT and later systems, as well as thin clients from people like NCD and Tektronix, so there were a wide variety of workstations that you would have been able to use.
People tend to forget what an enabler X11 was.
I was involved in reviewing and updating part of the platform security standards at a large UK bank, and I can tell you that the IT department are the police, not the legislators.
What happens is that a security policy is defined by either an IT security department, or by specialist consultants. This states things in very broad language, such as controlling user access and data flow between security zones. They don't specify technologies, protocols or methods.
The IT department gets this deliberately woolly and poorly defined policy (by definition, as it will be architecture independent), and then has to try and implement it.
Security people are all about saying no to things that they don't understand. The business people want to be able to do anything without restrictions. There is a natural and totally understandable conflict here.
The IT department has to work out what the business users really need, rather than what they want, and then convince the IT security people, who always have a veto that it is safe. This normally means that the IT architects are between an irresistible force and an immovable object. And always, one of the ends of the process think that the IT department have failed.
Having come up with a design that they have fought tooth and nail to be able to implement, and done so at the lowest cost possible, often in completely unreasonable timescales, the IT department then have to defend the decisions taken to the users, who very rarely have any thought about why security is there for anything other than stopping them doing their job.
Unfortunately, the group with the most influence are the people who feel that they earn the money for the company, even though they are the least qualified.
It's a no win situation.
used to allow three installs.
The current incarnation only allows one, and is more expensive.
I did most of the technical design for the backup/recovery and DRM of UNIX systems at a UK Regional Electricity System back in the late '90s.
The design revolved around having a structured backup system based around an incremental forever server and a tape library.
One of the requirements of getting the operating license for the 1998 deregulated electricity market in the UK was passing a real disaster recovery test. A representative of the regulator turned up on a known day, and said "Restore enough of your environment to perform a transaction of type X". The exact transaction was not known in advance.
We had to get the required replacement hardware from the recovery company, put it on the floor, and then follow the complete process to recover all the systems from bare metal up. This included all of the required infrastructure necessary to perform the restore.
First, rebuild your backup server from an offsite OS backup and tape storage pool, and reconstruct the network (if necessary). Then rebuild your network install server using an OS backup and data stored in the backup server. Then rebuild the OS on all the required servers from the network install server and data from the backup server. All restores on the servers had to be consisntent for a known point-in-time to be usable. Then run tests, and the requested transaction.
And where possible, do this using people other than the people who designed the backup process, from only the documentation that was stored offsite with backups, using hardware that was very different from the original systems (same system family, but that was all).
Apart from one (almost catastrophic) error in rebuilding the backup server (the install admin account for the storage server solution had been disabled after the initial install), for which the inspector was informed, but allowed us to fix and continue because we demonstrated that we could make a permanent change that permanently overcame the problem while he was there, the process worked from beginning to end. Much running around with tapes (the kit from the DR company did not have a tape library large enough!), and a frantic 2 days (the time limit to restore the systems), but was good fun and quite gratifying to see the hard work pay off. I would recommend that every system administratror gos through a similar operation at least once in their career.
We were informed afterwards that we were the only REC in the country to pass the test first time, even with my little faux pas!
When supply and distribution businesses split, we used the DR plan to split the systems, so having such good plans is not always only used in disasters, and I've since done similar tests at other companies.
My view is that it depends entirely on ho much has changed in the OS since it was installed, and that is probably determined by the function of the system being backed up.
I've worked in an environment where every server in the server farm is a basic install with scripted customisations, with all the data contained in silos that can be moved from one server to another (the bank I used to work for had been doing this on a proprierty UNIX since the turn of the century, before Cloud was fashionable). These systems can be re-installed rather than restored.
I've also worked in environments where each individual system has a unique history that is difficult to replicate or isolate. These systems need to be restored.
One example of this latter category is the infrastructure necessary to reinstall systems in the former category!
There just is not one fixed way of doing things. Each environment is different.
Bloody bloody. I must be slipping.
I actually read the whole of Section 9 of the service agreement policy to see the link with GiTS before the obvious smacked be in the face!
I was the one who brought up Tax discs, and I did refer to the Post Office being used to obtain Tax discs, although I did not sufficiently discriminate between the Post Office and Royal Mail. My mistake.
My other points about the Post Office in rural areas still stand IMHO.
If it were profitably for TNT et. al. to put a last mile delivery service in, they would. They don't, so it can be assumed that they have judged that it is not worth it. IIRC, Royal Mail originally said that they would at best break even doing the last mile (although that is really not descriptive of what is done), and would more likely end up doing it at a loss. Unfortunately, they were forced to do this in order to allow other companies to break the total monopoly that Royal Mail had for many years.
It is probable that residents of most medium sized or larger towns could live without a local Post Office day-to-day. It is similarly likely that rural areas need Post Offices more. But I would bet that many of the people who say that they can live without it probably do not know what they could use it for. They are for far more than just buying stamps.
You might like to tell the DVLA and the gov.uk websites that.
Damn. Bloody Americanisms. Of course I meant disc.
If you can live without a mail service, then I suspect that for you the Post Office is irrelevant.
But I also suspect that when you need your next car tax disk (assuming you drive), you may find one of the Post Office and Royal Mail services useful, either to collect in person or to deliver the disk. And if you don't drive then you are not typical, and your comment is irrelevant.
Or you want your next bank card to be securely delivered, or that job application that the employer wants documentary evidence for and you want to be tracked, or any number of things for which a physical delivery is required.
What you may not realise is that people like TNT and DHL (I think) and others actually use the Royal Mail for last-hop delivery, because they can't be bothered to raise the money to put a national delivery mechanism in place for themselves. If there was no Royal Mail to do this, these alternative services would become much more expensive.
And for may people, particularly in rural areas, Post Offices fulfil the function of Bank, basic shop and news agent, and social hub, when no other shop would remain open.
Royal Mail and the Post Office are not perfect organisations (especially in light of this report), and their role is definitely diminishing, but if they were to disappear overnight, you, along with everybody else, would notice at some point.
You're missing the fact that these are not single networks, but networks of networks, with fenced links between them, and at arms length from the core University networks. The only really complex part is the distributed user authentication that allows access to the core systems.
It really is a case of divide and conquer.
If you look at large corporate BYOD programs, one of the conditions is often that you surrender a lot of control of your own device. This normally means purchasing hardware from a list, installing company supplied tools like VPN, encryption and AV, and also surrender some control (have additional administrator accounts created). Certainly challenges the idea of it being your device.
What most Universities do is to have an open(ish) student network (or, in fact, many of them, often firewalled from each other and the main University campus network), together with a portal or gateway on each that allows them restricted access to the central file servers and other facilities of the core University networks. In addition, there is firewalled access to the Internet.
I don't see why that model cannot be used by business. It keeps your core network safe, while providing much of the access that is required by the user.
My kids were always told that it was their responsibility to make sure that their systems were adequately secured, and the only assistance given by the collage was to perform standalone virus scans. If the system failed the scan, they were offered one of the free AV packages, and told to either install and run it, or get someone to do it for them. Their machines/accounts were blacklisted until it had been proved to be virus free.
But in order to liberate that energy from a chocolate bar, you need to oxidise (i.e. burn) it in one way or another, and you need atmospheric oxygen, so you ought to take the mass of that into account as well.
Chocolate can be made to burn if you try hard enough, but I'd love to see you 'recharge' your burnt chocolate bar.
But the nature of a battery means that you cannot take the cheap route of just setting light to it. I suspect that the calorific value of oxidising the components of a battery may be even higher than the rated re-usable capacity of a battery.
In short, you're not comparing like figures.
In order to use this, you have to be an Office365 registered user?
OK, this is currently just for UK Government employees and information partners. and I know that I have to temper my dislike of Microsoft's business practices, but this feels like Microsoft just having to wait for all UK Government on-line services to use this mechanism before signing up the entire UK adult population on a subscription service.
Where's the openness, fairness and competition.
The difference is that while a Linux update will reboot a system once, there is a good chance that if you are updating Windows with other components (like hardware drivers), Windows will reboot more than once, sometimes many more times. It's got better than it used to be, but.....
Updating a kernel of any operating system on-the-fly is difficult, regardless of whether it is a desktop or a server system.
The problem is that the kernel is more than just another programme, and is being used all the time by running processes, and one of the things the kernel does is to track and allocate resources to the running processes. In theory it is possible to replace the kernel while it is running without disrupting the processes that it is controlling, but to get it right under all circumstances is difficult, time-consuming to test and thus costly.
A micro kernel implementation may be easier to update, but that assumes that you can re-bind running processes to new instances of a service on-the-fly. But even if you can do this, it is likely that there is one or more components that will require a system re-start if they are updated (the thread scheduler is one example).
With modern on-the-fly service migration, it may be possible to boot the new kernel in a different VM, and then migrate processes into the new VM, but most people just put up with losing their system for 10 minutes.
I used to drive past there every day for months without even knowing what it was!
That's one of the reasons why I always provision my own router. It's a cost I bear, but one I believe is reasonable to maintain independence from any ISP.
I don't trust them not to put some nasty spying functions in their firmware to leak information about my network and the devices installed on it.
That should have been Advanced Workstation Division (AWD) in Austin.
Not sure that the 801 ROMP was really intended for PC machines. It was originally intended to be the CPU for a dedicated word-processor, but was picked up by the Advanced Workstation Team in IBM Austin to fill a niche as a technical workstation for education and engineering use. It was most successful as a CATIA workstation, either on it's own, or as a front-end to a mainframe using Distributed Services. It always had weak floating point performance until the advanced floating point processor was available late in it's life. It was an important stepping stone to the RS/6000, p Series and Power systems, and the PowerPC processor, though.
Although the 6150 was originally marketed as a 6150 RT PC, it was never a PC per se. There is folk-law that suggests that it was going to be used as a PC, but looking at the reason why the 5150 was rushed out of the door as a quick-and-dirty temporary solution to stop the likes of Apple and various Z80 CP/M systems from dominating the market, it would never have been ready in the timescales required. That's why IBM used off-the-shelf components and a ready made OS and Basic for the system.
Of course, I was referring to non-I&D PDP-11, which I think that the LSI-11 was. I think that the J-11 and F-11 may have been separate I&D machines, but that only allows you to double the process address space, and even then, with serious limitations (64KB text space and 64KB data).
As much as I love the PDP-11 as an architecture, it would still have run out of steam in the late '80s. The problem was the memory model, and the mixed-endian nature of the system.
Without further architectural evolution (which was the VAX-11 in 1978), the PDP-11 was limited to 64KB processes (unless you used overlays) mapped into an overall 22-bit (4MB) maximum address space.
Don't get me wrong. It was a magic architecture, and because of the orthogonality of the ISA, I used to be able to decode PDP-11 machine code directly from octal dumps on paper. But it was a '70s architecture, not an '80s one.
The '80s should have belonged to Motorola 68000, NS16032 or 32032 (a very nice instruction set), or possibly ARM, running UNIX derivatives.
Just imagine if the IBM PC had had a 68000 with enough of a cut-down UNIX back in 1982. As soon as hard-disks became available (PC-XT time scales), we would have had multi-tasking full UNIX systems on the desktop, a bit like the AT&T 3B1.
PDP-11s survive (even to the current day and into the future according to a recent El-Reg article) because they are fine industrial controllers for systems that do not need large amounts of code to perform their function.
But Acorn User also produced a barcode scanner for the BBC, and printed their programmes as barcodes as well as listings that could be scanned in, complete with checksumming.
They had special yellow pages in the middle of the magazine so that you could find them easily.
Be careful with your Facebook account. There are many, many other sites that will use the Facebook login process to access their site (I think linked-in will, and I was looking at the On-TV app on Android that allows it - I tend to ignore it as I don't want all my accounts linked together). I think these processes work by logging into Facebook themselves, and seeing whether the ID that you've given is currently logged in.
There seems to be a group of information providers that would like to become single sign-on candidates. I've seen Google, Yahoo and PayPal as well as Facebook offered as quick ways of registering and authenticating for other sites on the Web.
Sounds like my Palm Trio. Still gives me a weeks battery life on it's original battery, and was very smart in it's time.
I agree that the header files are not necessarily authoritative, but unless you know somewhere else that is generally available, the header files may still be the best even if they are not very good.
Most people (and me, now) do not have access to any current UNIX source code. Generally speaking, although the temptation was there, I resisted taking snapshots of the various code when I left companies with source. I try to abide by the rules, even though in hindsight, I have often regretted being so 'moral'.
The only UNIX source code I have available to me now is the V6 Lyons commentary, and the V7 code that was freed up by Caldera.
When I wrote my previous comment, I had a bit of a dig around in the IBM AIX V7.1 include directories. I was very surprised to see almost no copyright notices to Bell Labs or AT&T (understandable), USL (I suppose that is understandable as well), or Novell, Caldera or SCO, and precious few to the Regents of the University of California at Berkeley.
It looks like IBM have been cleaning up the copyright notices over the years.
I am currently not working on any other platform to check.
