We aren't out of IPv4 addresses, we are out of IPv4 block allocations. This started back in 1992 when Cisco and Bay Networks decided that forcing new allocations into consolidated routes was easier than building routers that could cope with 2^24 (or even 2^32) unique routes. The original / notation wasn't about talking about/16 or 24 but/36 was a way to describe taking 4 extra bits from the source and destination port range. That system would allow most existing hardware (even from the late 80s) to work without any changes and allow things that know about the newer way to cope with more advanced addressing for things like vhosts.
Microware's OS9 from the early 1980s had a table that it checked for each module it loaded into memory. Each library or executable had a CRC that it checked against and then that CRC was checked in a lookup table of stuff to accept or not load. You could load that table with a list of approved memory objects and then only those things would be loaded and run or you could list things to exclude like an old runtime library in which case it would try to find an approved one in the path. This stuff was being done 30 years ago on 8 bit CPUs. It should be an option on every OS today.
It is checking the guessed key is right that is the problem. Say I take my credit card 4111 1111 1111 1111 and encrypt it with a numeric Caesar cypher, it turns out the encryption is bad but close 90% of the keys you brute force will give you what appears to be a valid answer (assuming mod 10 and 3/4/5 on the 1st digit checks only). If you take the same number with spaces and a EOL and used export grade DES you can try 2^40 keys but only a fraction will result what looks like a credit card number. If you use AES256 then the odds of a good looking result have the right key are even better so not only do you know you have the right key, your confidence in that fact is higher. Deep Crack used a lot of hardware to find out that an attempted key produced useful looking results.
My local government has decided to spend a fortune putting fiber^wfibre everywhere. Their decision has nearly bankrupted all the local fiber providers since they aren't getting any new business and the government mandated system isn't fast enough to support the cool things you can already do on dark fiber like put half your SAN in a different postcode. Yet they are still spending money to try to find the next killer app for their crippled speed network.
Right now many places have decided to leap in with a flavor or PON which is not much more than cable TV over fiber. The local bunch keeps saying it can grow in speed forever yet the largest user of it in the world (NT&T) has hit a wall and both AT&T and Verizon have both pulled back plans for future rollout. Its looking like shared isn't the way to go but no one has a good idea how to do direct point to point that isn't way too expensive to roll out.
As far as *PON being future proof, it has managed to get 40x faster in 2 decade in a lab compared to point to point which is now 20,000x faster using 4 decades of off the shelf equipment.
My Saab 93 manual says the ECM is inside under the A pillar. Saab and VW both use under the back seat for critical systems such as main control and ABS control systems. It is very common for new cars to have the spark generation system bolted near the spark plugs but they don't have much electronics there but that has been the case since the days of what was called "electronic ignition" where you would put a detector in the distributor cap and then have a heat sinked box with the transistor circuits bolted to some bit of the body.
Very little in the engine compartment gets to 50C most of the time and you will find that all the bits that do get hot are thermally insulted from the rest of the car. Engine compartments also have very good airflow. I can't remember every finding a hot part of the car that wasn't the engine, its cooling system or the exhaust system.
My 1988 VW had an analog computer running its engine management system which was tucked behind the center console.
I have a much newer 1975 MGB and it got hit by a pontiac 6000. There was antifreeze all over the ground where the cars made contact and the women said she was sorry for breaking my cute car and making it leak. I opened the trunk to make sure the spare antifreeze was still in its bottle and it was. The only damage the accident caused my car was it realigned the frame. The impact also fixed the trunk light switch some how and another light started working again so my car came out better. Her car had to be towed away.
NATO split up the spectrum after WWII so that European military radios were on the US civilian frequencies and vice versa. The reason was so the US military could take its radios into Europe and use their default channels and not conflict with the allied military radios that were already there.
If there is any change at all, the "pedestrian phase" will simply extend the green time by a few seconds or ensure that it is at least so many seconds long.
Ex is even better than ed... and is included in your favourite vi(m) editor as well.
An exercise to teach you to write better code is write it in cat. cat >test1.c and just type away. How many attempt does it take to do a simple program like counting to 1000? It should only take 1. How about more complex problems? The exercise can be extended so that you can then write comments for later editing such as/* remove the above junk */. I wouldn't recomened it as a way of writing real code but it gave me an idea of how much I depend on using the editor when thinking about the problem a little better would have been a better solution.
I've found the best way to describe vi's primary mode to new users is to imagine that you've been given a document with tradition edit marks.
Why do people use:wq in vi/ex?:x has done the same thing for 30+ years and:x! doesn't have the problem that:wq! parses the wrong way on some versions.
I doubt the application works the way the story says. I expect it uses a GPS position to find the nearest airport and then uses one of the many online services and the displays that data.
The only two things of vaule are the Documenters Workbench and some of the developers toolkit.
The Documenters work bench was the proofing tools for troff and its friends but its has some very good code based on data that only AT&T could afford to collect at the time. Its spellchecker keeps track of the types of mistakes you make and offers guess based on that too. If also had a feature that would reduce the vocabulary based on the type of document so that it would offer a different set of words for a technical document than a marketing one.
They have two things that would be good for open source. One is the old "Documenter's Workbench". It was a proofing tool that had lots of good AI stuff from Bell Labs. The other useful thing they might have as the old Toolchest selection of software. I figure either would be worth $100 or so just to release into the public domain. The spell checker in the DW had some interesting stuff like knowing how you make typos and it also had some ideas about reducing vocabulary so the wrong synonym was less likely to end up in your technical document.
Culture is reflected in its language and its language reflects its culture. One of the reasons that the US, UK and Germany did so well in the early industrial age was the use of compound word which could be created to describe new devices. This makes it easier to describe a new invention to someone in a letter than less adaptable languages.
The base test system is GPON which is 2.4 gig shared with 32 or more users and if you swap out the line card, you can upgrade to 10GEPON and then the CPE needs to be upgraded and you get faster data. At the current subscriber pickup rate, you can give everyone 1 gig and no one will notice. I expect the "1 gig" is that device at the home will have a gigabit ethernet port where the base gear has 100 mb ports. I've seen a picture of a device installed for the Tasmania trial and it appears to have a Verizon asset tag on it.
The NBN may be a PON based network running at 2.4 gbps which is shared with 32 or more other subscribers is now going to provide gigabit internet. They are rolling out the same stuff that Verizon is using for their FiOS system and they are only offering 50 mb data links. The current test system in Tasmania is 4 times faster than the existing HFC cable TV system in Sydney and Melbourne and that system is offering some 100 mb connections so I'm not sure how the oversubscription works with either system.
The largest problem is the near total lack of reasonable priced back haul into most exchanges. The coalition's plan seems to address that issue. That would allow small wireless ISPs to start up in the rural areas which could serve people who have been ignored at this point. They are also removing all the pair gain systems which are mostly no longer needed now that the number of land lines is going down quickly. There seem to be some regulatory things that they are trying to simply as well. Now that the duct network is valued at $11 billion, it means the ACCC can set rates for rent of the existing Telstra ducts that are much lower than the current rates.
A major problem I see with the NBN is that anyone that has access to more than one ADSL2 provider will be the last to get access to the new network as their focus will be the least severed homes first. Meanwhile there will be very little maintenance done on the existing networks. That means most of the fast internet users from today won't been seeing any speed advantage until after the next election and about 1% will see their speeds go down as problems on the existing network effect their speeds.

Victoria is almost unique in the world in that its accident rate per km driven is going up.

There was another option that also failed but parts still live on with the decedents of X.400 and X.500.

Why you ask?
The answer is gravity can not push.
If you throw that out, all sorts of things open up but it make for a huge mess on modern physics.
But I'm okay with that until someone can explain the Pioneer space probes doing odd things using the gravity pulls model.
The HUD should display in the rear window since that is what drivers should be looking at.
