Further complicated matters, the 13 states had very different population sizes; the populated states thought that they should have the most voting power, but there were concerned that more sparsely populated areas would essentially be overlooked.", "To solve this problem, they set up the American system of voting. Any candidates that meet the qualifications may run, and state receive a set of electors equal to the number of Congressional representatives they have. States have, at a minimum, 3 representatives: exactly 2 in the Senate, and 1 or more in the House of Representatives based on their population from the last Senate. Electors tend to vote for the candidate that wins their state (some states legally require this, but this is not true over the entire nation), and in Maine and Nebraska, the electors split their votes according to state laws, in which not all votes go to the winner of the state. Whoever has at least half the electors voting for them wins.", "Further, in the original system, the runner-up becomes the Vice President. Because the Vice President has only 2 official duties (to carry out the President's duties if the President can't, and to break ties and preside over the Senate), it was thought that this wouldn't be a problem. The 12th amendment changed that (I won't get into all the reasons here; Google if you're interested). Under the 12th amendment, electors vote separately for a President and a Vice President, and it is very strongly expected that the electors will elect the VP of the Presidential candidate's choice.", "Further, because they expected more than 2 candidates, they had a solution if nobody get a majority of electors: the take the top 3 candidates and the House of Representatives votes, with 1 vote for each state cast. This happened only 1 time in U.S. history (1824; interestingly enough, all the candidates that year were from the same party).", "Today, we have 2 overwhelmingly dominant political parties that are extremely bitter rivals.

I won't go into the whole process, but suffice it to say that any attempt at electoral reform would not favor the politicians who got into office, so they have no advantage in proposing reforms.

Isn't this just a fancy word for old technology? I often see a lot of non technical people become confused by this word.
{ "comment_id": "t1_daph7go", "comment_text": [ "So all the answers so far miss some key parts to the story. Why should you take my word for it? I'm a senior engineer with 20 years commercial experience, several of them in ISPs and Telcos, and I've been working a lot with cloud technologies for the last 6-7 years or so.", "To make sense of the difference, let's go back in time and figure out what changes people made.", "The very first computers were large and cumbersome. They lived in the place where they were built, and were used by the people who built them. This was the case in the 1950s.", "In the 1960s it became possible for a computer to be built somewhere else and delivered to you. A large computer would need a specialised room, known as a \"machine room\" (although it was sometimes called a \"data centre\" to make the horrific costs more relatable at board level). A company buying a new computer would find some space in one of their buildings, raise the floor (so that power, cooling and other systems could go underneath the computer components), and the computer would be installed.", "In the 1970s computers became smaller and so these machine rooms would house not one big computer, but perhaps several smaller ones - albeit quite large by today's standards.", "By the 1980s computers got to a size where you could fit one on your desk. However, you'd want it to be able to talk to your company's bigger computer, or perhaps a computer in another town. Clients and servers had been around for some time, but now they became much more popular. Even smaller \"big\" computers were now put in machine rooms that were rebranded \"server rooms\" or retain the title \"data centre\".", "In the 1990s, the Internet started to take off. Even before the web, small independent ISPs were popping up, each of them with very different kinds of server requirements. By now it was possible to take a standard PC, put the internals into a rack mount case, install a server operating system on it (Linux, FreeBSD, etc.), and put it in your ISPs machine room/data centre for a fixed monthly or yearly cost. This is called \"co-location\": you buy hardware, you go and install it in a data centre, and if it breaks, you need to buy replacement parts and go in and physically service it yourself.", "One of my first jobs was looking after one of these sites, we'd have hundreds and hundreds of machines brought in by clients every year, and we'd rack them up, and plug them in - they'd have access to high-speed (for the time) Internet and power, and be in a climate-controlled room with good fire suppression. These rooms were not nice places to work quite often.", "After a while, somebody realised that people would want a server to host a website on, or run their own email server, but they didn't want to buy the equipment, or perhaps wanted to try it for a few months to see how well it worked before making an investment. That led to a lot of innovation.", "First, there were dedicated servers. These are machines you rented per month. You specified the OS, and it was \"your\" machine (you didn't share it with anybody else), and you could cancel with a months notice. You could install games servers, web servers, whatever you wanted on there. The main advantage is that if the hardware failed, it was your server provider's problem, not yours. You would know your system's specs, but you'd never see the server itself.", "At the bottom end of the spectrum was application-focused shared servers. You'd pay £5/month and get some space on your provider's server for a web site, or for email hosting for your own domain. One of the problems with this model is that if you're sharing a server with a \"noisy neighbour\", your website or email can slow down as well as theirs.", "Next came the idea of the virtual server. A virtual private server (VPS), looks to an engineer to be like a dedicated server, but it's actually an imaginary server running inside a real dedicated server. It's almost like a hybrid of the previous two approaches: you're sharing a server with other people (so it's super cheap), but you are able to install what you want inside this virtual server (so it's flexible), and if the server has a hardware problem, it's not your problem.", "And that's where we were for many, many years.", "A lot of effort went into making virtualisation really good. One company - VMWare - got to a point where I could take a virtual server on this physical machine in this data centre, and drag it over to a completely different machine in another part of the data centre, and it would carry on working without a reboot. Quite amazing, really.", "Lots of companies though had a problem: how many servers to buy? If you imagine that for a few days a year - say Black Friday weekend - you are incredibly busy and need 100 servers, but the rest of the year you are very quiet and only need two, how many do you buy?", "Well, if you're co-locating, you buy 100 servers. You need to provision enough for peak load. That's quite wasteful. If you're on dedicated servers or VPS's, you might decide to rent 2 machines 12 months of the year, and then say in October rent 98 more and get them ready, and then in December cancel them - three months for a few days is still quite wasteful.", "What people wanted was a model where they could scale just in time for when they needed the capacity, and only pay for what they used. The day after Cyber Monday, ideally I don't want to still be paying for these servers any more.", "Amazon knew this more than anybody - because this is what they wanted. The problem is, at Amazon's scale, this stuff only make sense if they own their own data centre. They weren't just co-locating, they were going back to the 1960s model of building physical spaces they owned for this stuff. But if they could get other businesses to share these machines with them - perhaps using the exact same model that Amazon themselves would want - it could offset the costs, and indeed move the data centres from being cost centres to profit centres.", "And so we got to cloud computing. The key things that made cloud so radically different to what came before were:", "These combined, made a lot of people rethink systems administration and what it meant to \"run\" a web site or application. It has radically changed the industry and allowed for huge efficiency savings.", "Interestingly, that's meant that we're now in an era where Amazon themselves and others are building tools on top of all this that aren't just virtual servers by the hour, but more like applications. Want infinite storage capacity? Here's S3. Want to install a message queueing system but getting confused about RabbitMQ? Here's SNS and SQS. Fed up of having to run an email system? OK, here's SES. And on, and on, and on.", "Some companies think about how to solve a developer's life a little. Heroku for example provides an interface where the developer doesn't even have to think about servers quite so much. This is called PaaS or \"platform-as-a-service\". In this model, I don't even auto-scale server, I just deploy applications.", "Others have gone another route: Docker is a good example of a technology that looks at how to have auto-scaling and immutable server images but based on your own hardware, or even on cloud hardware that you scale at a layer removed. Funky.", "And then there is serverless. Serverless - AWS Lambda and Goolge Function makes the world a strange place. No longer do we think in terms of applications or servers: we think about a single function in a piece of software and just give it to the cloud to run at infinite scale, paying every time it is invoked/called, so we don't even pay for the capacity of a server we don't need in a quiet period, and the \"auto-scaling\" is automatic and seamless and needs no management.", "Google and Microsoft were late getting to the party, but they're now gunning for it, and it's getting interesting.", "Back in the late 1990s I had my own server, onto which I would install various things. Cost me a fortune, and I only got to co-locate it free because I worked for an ISP - I wouldn't have been able to afford it otherwise. Today I just wrote an application in for Lambda that if it got 1,000,000 hits a month would cost me perhaps $4 to run it.", "And ", " the difference between a server and the cloud." ], "score": 10 }

This model of programming splits the processes a program performs into \"objects\" which perform tasks from certain inputs and give certain outputs. By splitting it up this way a programmer doesn't need to know how every aspect of the program functions in order to work on it; each object is a sort of \"black box\" where what happens inside is a mystery. An example object might be a pricing module where it takes a list of product codes and returns a total price for the order.", "There likely isn't very much different in that pricing module for object-oriented programming compared to just writing the item price lookup, bulk order discounts, etc. in traditional programming form. But by doing it with the object-oriented model you can easily have multiple programmers working on the same project without interfering with each other. Someone can write a module to generate a shipping route for all the items without ever knowing about what is going on within the pricing module.", "Bringing this back to the Cloud, the term is more for talking about using decentralized remote servers as infrastructure rather than a local hardware solution. True, it is all servers like before just how the code within objects is the same code as would be written without the object model.
