What it be possible for a multicast to work with unicast corrections?
The receiving node must be aware when a packet is not received, if it is not at a packet level, perhaps at a more logical level like a block of data. Rather than wait for the next multicast, it explicitly requests a retransmission of that block to that node via unicast.
I am of course assuming that only a few packets would get lost.
Or perhaps another corrective multicast that streams corrected packets when enough people request them.
MULTICAST degrades to multicast with corrective unicast recovers to corrective multicast
I imagine this would be beneficial when a piece of hardware generally botches packets, such as a switch. If that ever happens in practice, I have no idea.
Is it possible to use multicast? The multicast could run continuously or on demand. Can you route multicast?
It would be pretty impressive if one could attach 3 nodes to the network and they all boot up.
It would be a Borg network. Everything you add to it would be immediately taken over!

The breakthrough nature of this is that the hypervisor or the host OS is providing a virtual machine to every guest OS in the system. A virtual machine provides an environment that mirrors the real hardware, the OS knows no better. This in theory means that you could run multiple Linux distributions with the memory of a Linux kernel only being used once, meaning more applications can be run within these guest OSes or more guest Oses.
I agree that the GUI should be as flexible as possible.
Although you really are dealing with two forces: GUI code is something that will be executed more than any other application code, it ought to be very fast and efficient. At the same time, humans are rather slow, begging the question if optimizing the GUI code is worth the performance gains.
It's interesting how thousands of objects can potentially slow down GUI controls. Should they?
I presume that GUIs are often object orientated because it makes GUI design easier and more flexible. This makes styles changeable on the fly and hence slower.
If you take a look at Java's GUI related design you will find that a lot can be overriden.
I would love the day when I can select one of a number of default layouts and workflows such as Windows, Mac or a particular Linux distribution and have lots of platform specific details set themselves - while being fully revertable. It would be clever if the policy were completely separate from the mechanism so that even fine grained behaviours like where buttons are placed, dialogue button order. They could even be mixed together if that is desired.
Imagine having a Windows centric 'screen', Ubuntu, Mac and whatever else without leaving the same OS...not that there would be much point.

We're a shop keepers nation who have very little to offer the world but services. So many businesses outsource or close factories to open them in Europe or elsewhere. Cadburies is not even British anymore which is ridiculous.
Programming is a service!
I really do fear for the future of the UK. What do you think we can do about it?
That may be true but nowadays the real innovative stuff comes working on the abstractions built on others. Look at BitTorrent/Python, Javascript/AJAX, Facebook/PHP,
I'm not saying they aren't implementable in C but seriously, they ORIGINATED on the later languages, that should tell you something.
The people with the ideas need to get things into computers and if it's easier not to know what registers are or whether it will be faster to do a SPLIT operation.
What about the algorithms that were invented in abstracted languages? In an earlier post someone said something about the guy who went to work at Thinking Machines went in only knowing BASIC but made some fascinating algorithms.
I think the most important thing in computers and computer science is problem solving, the algorithms and approaches to problems.
if they don't know C or don't want to use C, all the power to them.
How long have you been programming in the real world, for a business?
This sounds pretty naive as it seems you are really are missing a large part of the world that depends on Java and rightfully so. Hardware changes, VMs do not, as much.
It is news if it is new in context, however uninteresting. In this case, something was added to Windows that was not there - that's news. Windows is here and unfortunately some of us have to maintain it. The package management (or whatever it is) is new to windows and will hopefully be good news to the admins here!
I'm inclined to think that computers = headaches in general anyway, whatever the system.
The western society is a 'servce culture', we exchange value by doing things for one another. The east culture is a manufacture culture. In the UK, our youth look up to playing instruments, video games, being footballers or engineers - doing service related things. In China, education is very important and cut throat. It's more about being a mathmatician, engineer or scientist. In my book about China and Microsoft (Gwanshee), the Chinese can get into university degrees as young as 13!
They are reducing our production capability - they manufacture a large number of things for us so we can do business cheaper. This is a massive stranglehold they have: we benefit because our businesses can do things for less. It's no longer profitable for us to run factories and production workshops in our own territories. This means we become dependent on them, like sucking from a teat.
What do they get from it?
Skills, knowledge, experience to bolster their own country. We get nothing. If we send an Apple engineer to overseer production of an iPod*, who is actually learning how the technology works? Do you think that it's really private from the native factory owners? We're essentially giving them technology and abilities. We have seen them building factories, power stations and transport links that put ours to shame, they are really building themselves an impressive infrastructure. They fund international scholarships to put the skills they learn to good news.
We're digging ourself into a roadblock. What if China cuts us off from manufacturing? It's not as though ALL THE businesses have absolute control, they could not avoid retribution from the government!
We would be screwed. The UK practically builds nothing by itself anymore, we just let China do it. If they stop, we're unemployed and opened for expansion. I think they are grinding us down slowly and surely.
What do you think of China? What can we do about it?
Some people have public search profiles (the ones that appear on Google) which means in rare occasions your name can appear in the brief list on the cached Google copy. That's what I was referring to. This associates you with that person, giving someone a lead on you because you are now associated with that person, however mysteriously.
There is also the share Microsoft owns which is suspicious and also how it can be used within a police society (say Britain).
Another thing is how some pictures have ended up being used in marketing materials. Do you want your pictures to be just a URL away from anyone using them for their own purpose, potentially profiting from them?
I do not see how difficult it would be to write a script that:
downloads all your friends photographs
run face recognition on your friends, using the DHTML div region to work out general area for face to simplify algorithm and train some software
Use face recognition software on new pictures = instant ID
Imagine this on a government scale, CCTV pictures that track people's first and last names as they walk through public places. The technology is here, do you think it's beyond CSA, NSA or SIS/MI6 to use it?
PS: if you use this in your dissertation or thesis please at least link to me here.
I deleted my Facebook. Everyone asks me why, here's why:
Privacy: I do not like the fact my photographs are available and indexed by my own name. Someone could find out everywhere I have been based on the album, the photo and the dates.
Shallowness
The quality of communication on Facebook is poor. The most indepth conversation you can have is what someone is doing and what they have done. You are not promoted to have an intellectual debate (Read: Why the hell am I on Slashdot then?) I much prefer to use email although If my email clients were more like how you send messages to people on Facebook it would make me very happy.
Trendy
The people on Facebook for me are the wannabe trendy people. One or two years ago I tried to get my friends to join Multiply, it focused on contribution of blog postings, news, links, pictures and videos. It was difficult to get people to contribute things that were worthwhile.
Cloud storage
All your messages and photographs are stored remotely. Facebook also converts your photographs downward in quality and makes them easier to share with people so most people only ever see the low quality pictures. In other words, it's not a lossless backup medium. At least with email, my email may be hosted but I can still download my own copies.
Excessive Openness
: You could set your privacy settings very high but your friends will give you away. At least one of your friends will have settings that expose their list of friends, including you. This means people can deduce your whereabouts and who you know quite easily. Another thing is that if public search results are enabled by your friends, you can still be exposed through Google search there! If I were an employment agency, it would be trivial to make friends with one of your application or request happy friends (such as a distant young relative) who accept any request that comes their way. If your privacy settings are set to 'Friends of Friends', I see practically everything. Anyone in the same network has the 'right' to see everything about you.
Keyboard unfriendly
I may be a Windows user but I love keyboard control, I write this in VIM and my mail client is ALPINE.
Slow
On all the browsers I have used Facebook is slow. I underclock my laptop and it's annoying to have to return to normal speed just to use a website.
Developers
Mark Zuckerburg is not very nice. I do not believe in software patents but apparently he stole ideas from his fellow classmates. You can understand if you had an idea and someone stole it, without giving you credit. Zuckerberg sued by classmates. When some of the Facebook PHP code was leaked (Revealing Errors, Facebook source, it was rather disturbing what was written: 'put hotties there'. Also the news that the master password was once 'Chuck Norris' (master password) is rather disturbing. I do not think the developers are competetent. Especially something as privacy critical.
Abuse
The potential for abuse in Facebook is huge. Law enforcements can request practically all data about you see this Cryptome leaked document. The amount of marketing information they can collect on you is more than anywhere else, they have your profiles, your fan pages, browsing habits and internet usage patterns.
So rather than provide me with sources or evidence, you call me delusional and tell ME to look for sources?
The good old Nokia phones that are just are mobile phones last longer than any iPhone can - how can you compare something that has barely been around to something that has been around forever? The battery life of a Nokia phone trumps the iPod.
With that attitude, you'll feel it impossible to be proven wrong. They call it 'planned obsolescence'. I do not see how you can think otherwise, they release an iPod or a new iPhone every X months. They need people to buy new ones. I cannot be the only one to think that newer gadgets fail quicker than they did in the past.
Anyhow, my original generation iPod is flaky just about one year after warranty. I imagine my case is not the first and only example of this. It makes business sense to have hardware fail at a certain time.
The question is what is the bigger scam? Warranty or planned obsolescence.
After being screwed by Microsoft in the past, it's pretty obvious why Apple is so aggressive nowadays. It's taking taking some pages from Microsoft.
I am with Nokia because they're quite nice with Qt and they are definitely rightly responsible for a lot of technology that no doubt Apple just implemented without permission. I think the fact that about 40 firms* paying royalties is evidence enough.
I will not buy an iPhone and never will be part of that monopoly. iPods, iPhones are engineered to fail and you paying ~£30 for the privilege to do very little.
Shared scores are just an easy way to make a singleplayer have multiplayer features - it is not interactive in the slightest. I could not care less about games where only the score is the competing factor. I want to see the other player and interact with them directly.
This is good news of course but what does not make sense to me, this refers to Google and iPhones as being cross platform games.
How come there are not any great games on normal Java phones? J2ME has so many libraries and they're capable of the same.
I have never understood why there are not many multiplayer bluetooth or games that connect the internet? It would be awesome to play net games on the phone on the train with people in the same train or anywhere in the world.
If you build something more efficient now, you can do more than you could originally.
That makes sense.
If a kettle takes half as much electricity to boil water than it did before, you can boil twice as much water with the same electricity right? You end up using more hot water for other purposes? Like more tea.
Someone else can provide a car analogy, I don't have a licence to drive.
Is what he is saying? Ultimately we are just trading energy for more of the same work, right?
Google is the Foundation

The one thing about Google you have to understand is that they employ lots of very smart people: they employ scientists, research graduates, economists, technicians and business people. They have calculated with sheer intelligence all business moves: they know what they need to do to get the best business and business position.
In short, they are the foundation. Eventually they will collect all human knowledge and make the encyclopedia that encompasses all human knowledge... this is just a rouse for the real purpose of Google...
Some companies have actually jumped onto this and have developed 'open source auditing software which looks for OSS sourcecode or installed software.
Take a look at the Silhouette Scanner page. I have no idea what it is like but it is quite shocking that it is being done. I imagine there is a market for this for large companies especially. If I was a large company and was outsourcing coding to other companies (or countries), I would want an automated tool to run back home to verify its integrity.
Although I imagine it can be abused equally. If you know what the open source product is and where it is, you could probably obfuscate it.
No problem, I couldn't remember where I had read it but a few researchers did claim or make it appear as if it took less effort. It's really annoying when you forget where you read something.
Sorry for the weird typos, my brain is between DVORAK and QWERTY and does not seem to be able to handle the changeovers that very well.
That definitely makes sense if they do develop products.
