Tell me more about how when something that you can pay money for gives you an advantage, it is intrinsically unfair that other people can not afford it?
I have been thinking this about the internet of things as well. Then when they roll out IPv6 we can put all of our extremely dated hardware directly on the internet!
Besides spying on you, the router its self could likely be used in a botnet as well. Think, origination of DDOS attacks, sending spam, anonymous hop for criminal activity (with your name on it).
All good points, but in that case you do not need to deprive people of the ability to take their own photos... the professional ones will sell themselves, or not.
This is also true, but at least the Linux dhcpd also tries to reunite the client with a previous IP that they had on new requests. From the dhcpd.conf(5) manpage:
When the DHCP server allocates a new address for a client (remember, this only happens if the client has sent a DHCPDISCOVER), it first looks to see if the client already has a valid lease on an IP address, or if there is an old IP address the client had before that hasn't yet been reassigned. In that case, the server will take that address and check it to see if the client is still permitted to use it. If the client is no longer permitted to use it, the lease is freed if the server thought it was still in use - the fact that the client has sent a DHCPDISCOVER proves to the server that the client is no longer using the lease.
So you are trying to say that routers have a hardware implementation of a map data structure instead of system memory, and that map is somehow mysteriously backed by non-standard computer memory.... Further, you suppose that this hardware based map uses more power than a software based approach, which directly contradicts one of the main benefits of using ASICs in the first place. So, are you a troll?
DHCP servers typically try to give clients their old IP addresses based on MAC address. This usually works until there is a huge demand for reservations, and the pool of free addresses runs out. This is uncommon in broadband networks where the number of clients is relatively static, and clients are rarely restarted.
If by "computer" you understand "general purpose / user programmable computer", then the differences are easy to explain. Neither the wi-fi card nor the smartphone have a built-in general purpose programming language/environment for the user to play with.
On the same lines one may notice that contemporary Windows PCs are not "computers" in this sense either. Back in the past they used to, but these days they don't come with any sensible general purpose programming environment either.
I do remember the days of the Spectrum / Commodore 64 etc. Now *those* were computers - they booted right into a programming environment.
So you are trying to say that if someone else, but not you, can program a computer... it is not a computer. By this definition my computer is not a computer, because you can not program it.
Can you explain what a computer is? For example: Can you explain why a cell phone isn't a computer--despite having computer pieces--but a smart phone is? Can you explain why a wifi card isn't a computer, even though it's running an operating system managing software and hardware?
I see what you did there... it is a trick question, they are all computers.
I just tried to cruise the comments section using the beta, and that is where things are the worst. There is no quote parent button, and it made me copy and paste the reply title by hand. There is no link to get a permanent reference to a single comment. Comment text does not show bold or italic. Quoted text is merely italic, but not indented or anything.
The mixture of serifed and sans-serif fonts feels disorganized, and does not seem to serve a clear purpose.
Comments are the heart of Slashdot, and the current beta offering is not complete. It is more of an alpha... functionality is woefully inadequate.
Curated articles are what set Slashdot apart from hive-thought sites like Reddit. Keep the articles unique and on topic, that is why I visit.

This sounds like my parents house.

Is an Ubuntu machine with three NICs. The firewall is configured with the Shorewall utility. It only needs to be rebooted for kernel updates.
Well said.

My earlier reply to this comment did not make sense, because I did not fully read what you said. I am sorry for trolling you.

Your carrier does not give you these addresses. Anyone can use them on a local network. http://en.wikipedia.org/wiki/P...

They also know that skilled employees are hard to find, mistakes happen, and that forcing good employees to be slaves will make them quit!
No, the contractor charges accordingly, and eats the loss for the wall not being built correctly. Most laborers will not work for free.
Then it counts if anyone can program it, for a thing to be a computer...
I've been running a half dozen businesses (with 40 people working for me) on Linux for 20 years.
Are you doing this with the hypothetical throwaway PCs that you mention?

Except... Verilog... VHDL... oh nevermind!
Once it needs to be longer than the circumference of the earth, we will have a super bad ass space station.
I always thought they were more of a pain in the ass than anything, like doing work for free.
Eventually we will be able to use the old one as a subway around the entire planet.
I used to get them all the time, and without anything changing, I have not seen them for ages.
If it needs to be completely different, all of the functionality should at least exist. Otherwise it is Slashdot alpha, not beta.
