Note you should expect a few months delay between release of a new version of MacOS X and release of the open source components on this site, but up until now they have always delivered.
MacOS X's core OS is open source. You can download the kernel and recompile it and swap yours in if you want to, and all the standard user space stuff is basically FreeBSD.
Also, it is a certified UNIX 03 operating system, so it is more "UNIX" than Linux, which is what I assume you're comparing it to.
Just to provide a link to make life easy (source is available up to 10.8.4 and includes BSD licensed stuff. Code for the UI level is not provided.):
The true length of time of a trip should be measured door to door, as should the cost. For that reason, the length of time of the local transportation, getting you to your long distant transport, should be added to that. Additionally so should an processing time at each end.
In Europe, it has been shown that in certain cases the train is faster that the plane when considering these factors.
In terms of design many of the high speed trains have significant innovation when it comes to safety and performance. The two tat stand out are the TGV (bogies in between carriages) and the Shinkansen (all carriages drive the train).
You shouldn't count the train out yet. I realise it is popular, in the USA, to look down on the train, but if you look the train certainly has places where it works well and possibly better than the plane in terms of door to door. The same can be said of the aeroplane in other cases.
Sure it could probably be built on and improved, but the real issue are the browsers. I just checked on MacOS X with Firefox, Google Chrome, Opera and Safari. Of those browsers only Firefox and Opera supported APNG.
The kickstarter should, IMHO 'focus' on:
- APNG awareness (available converters, creation tools, viewers, etc)
- Getting key websites to support it. I am thinking of sites such as Tumblr.
- Pushing for support in other main-stream browsers (IE, Safari, Google Chrome)
Is the USA the only nation with such a project? With other countries going into space, satellites and the ISS you would expect either and international program and funding or each country having its own equivalent?
Does anyone know if the US is the only country tracking space junk?
From my experience multi threading is a weak point amongst many programmers, with few getting it right.
Multi threading is about having the right tools and architectural understanding, since without it you might aswell focus on making your application work well in sinle threaded mode - I say this because without the right understanding you are going to end up with deadlocks, race conditions and code that might end up being slower.
I can remember a demonstration that showed that below a certain amount of "work" it was better to use the CPU and then above that to use the GPU. I can't remember the details, but from what I remember it was because of the overhead of setting up the cores?
I agree with the OpenCL route, simply because of previous history of 3DFX vs OpenGL. Short term CUDA has the advantage.
This. OpenCL is C based so it shouldn't be that hard to pick up. The efficient algorithms will be basically the same no matter what language or bindings you use.
Well, the first thing is to understand parallel programming and what sort of things work well in a GPU. With that basic understanding, then OpenCL becomes a tool for doing that work. Starting with an OpenCL based "hello world" type application would then be the next step.
The CBC did a good documentary describing how Hitler got into power how he manipulated the German population into supporting him. The series is called "Love, Hate and Propaganda":
I can imagine a few other issues:
- load not being consistent from aft to stern
- a rogue wave (though I didn't see any mention of it)
- buoyancy change due to an area of reduced salt density
- a structural defect
There are all sorts of factors and until a complete investigation has been done, we are only dealing with imagined possibilities. In the case of inconclusive evidence, I would imagine proposals for avoiding this in the future would be based on most likely cause?
This is the first model and if there is enough interest this will spurn research into how to get around these limitations. Even if the problem isn't solved for this particular scenario, there are bound to be other scenarios where waste energy is still hotter than the ambient air. Think of a furnace for example.
Part of the challenge of innovating is doing stuff despite being told it shouldn't work and finding a suitable application when it finally does work.
It sounds like you never went to the Sahara. I went to the south of Tunisia, during the cooler months, and it was 25ÂC during the day and dropped to around or below freezing at night. The ice on the car in the morning was testiment to how cold it got.
Reading online I see it can go from 40ÂC during the day to -6ÂC at night.
There are cross platform solutions such as OpenGL and OpenAL. If games developers focused on them, then I don't care about the state of DirectX. The fact we see games being released on Steam that can do cross platform, shows there are alternatives to MS API lock-in.
We knew this was going to happen, since I don't think they could have done otherwise. The question is what the punishment is likely to be and how is the public going to react to the sentence given?
Legally what Snowden did was wrong, but from time to time the government needs its dirty laundry aired, so that is can be kept accountable. The matter is not a question of whether the government needed to do what it did, but whether it was in line with what the constitution permits. By having a general idea of the actions of the government, we can at least have a healthy debate to know whether they are approaching things in the right way. Knowing the details of each case is not needed, on the condition someone is holding the watchers accountable.
Looking at Wikipedia page it indicates the song is from 1893 (see: http://en.wikipedia.org/wiki/Happy_Birthday_to_You). How the heck can anyone claim copyright on it at this point? Sure the last of the two artists died in 1946, meaning it is currently death+67 years, but I still think it is way overboard and agree with it finally needing to be put into the public domain.
I think we need to revise copyright such that the copyright after death is much shorter, but add a notion of attribution in each place for after its expiration.
With regards to the RAM, being limited to 4 slots may not be an issue if each of the modules are 32GB and in a year or two the modules could even be 64GB or 128GB each.
The shorter answer would be no. Its not expandable, an incompatible rare expensive *external* interface is simply not a solution. Although I do find it somewhat ironic that you could argue that a raspberry pi costing $25 is upgradable too:).
Actually, given the new ThunderBolt speeds I wouldn't be surprised if some company ends up selling an external housing for expansion cards. We are moving to a point where so much can be externally expanded at minimal cost.
I am also curious to know when sort of stuff MacPro owners traditionally add in terms of external expansion?
I have always wondered why this is something that couldn't be delegated to the operating system. Does anyone have any ideas? Is this something that could be addressed in OpenJDK? Can we use icu4j instead?
Where is the advantage to home users if they use IPv6? If you buy a router that is interoperable with IPv6, what difference does it make to you if the network provides a IPv4 or IPv6 connection to your local network?
Getting IPv6 now means they aren't asking why "new service x" isn't accessible, in a year or two. The advantage is not a marketing one (though it could be spun that way), but a technical one of avoiding breakage.
There are certainly some things that need to be in place:
- IPv6 firewalls on the PC side
- IPv6 firewalls on the router
- Routers whose UI hides the complexities of adding IPv6 as part of the solution
- Better education on the tech side - there are still a lot of tech guys who don't have a basic understanding of IPv6
Users don't even care today that they are using IPv4. All they care about is that they are able to using twitter, facebook, google or whatever else their favourite service is. As people push off IPv6, then we are likely to see more kludgy hacks that cause subtle issues. As more hacks get in they way then things like NAT busting algorithms are going to have to deal with multiple layers of NATing in certain cases.
In a LAN situation you can get away with IPv4 forever. The issues is dealing with the WAN. A temporary solution that many companies can put in place, if web access is the only thing that is important, is a web proxy that can speak IPv6 on the outside.
But its still difficult to get an ipv6 home connection in many areas. I can see that for years to come we will have an ipv6 backbone, ipv6 in amjor organisations but most people connected via NAT and an IPv4 isp
In north america this is the major hurdle. There are too many people trying to push the problem down the road, to the point it will finally bite them or their customers. I work for a large US corporation and their answer is "yeah, yeah, whatever, too much work, too short sighted". What is often missed is not the the USA or Canada is running out addresses, but the rest of the world practically has and that we will end being cut off from new services, who can't new IPv4 addresses.
If you want IPv6 today, then your main option is to get a tunnel via a broker such as Sixxs or Hurricane Electric. It may also be worth phoning your provider and seeing.
Some services that are already IPv6 enabled: Akamai, Facebook, Google, Youtube, Amazon WS, Netflix.
If people want to make a choice, then surely they should have the necessary information to make that choice? Also, a product that prides itself in not using GMO plants should have the right to label it? If companies like Monsanto are so afraid, why are they preventing other companies communicating something like this?
Fixing the regulatory process is hard, when the entities that are meant to be regulated are often in collusion.
Several reasons:
- Monsanto is American, and therefore are in a good position to influence US government
- There have been several attempts to label stuff, but companies like Monsanto have been able to put a stop to it. - http://ens-newswire.com/2013/05/24/u-s-senate-bars-gmo-labels-as-march-against-monsanto-revs-up/
- I am guessing that in other countries the population either cares more about their food or have more influence over their governments?

No it isn't open source. They haven't released their code in a long long time.
10.8.4 is the latest and is available: http://opensource.apple.com/release/mac-os-x-1084/

I should mention there is a plugin-in for APNG support in Google Chrome, but that is still a handicap:
https://chrome.google.com/webstore/detail/apng/ehkepjiconegkhpodgoaeamnpckdbblp
A quick search turned up this tool for converting animated GIFs to APNG:
http://gif2apng.sourceforge.net/

Learn OpenCL and do the job properly.
This. OpenCL is C based so it shouldn't be that hard to pick up. The efficient algorithms will be basically the same no matter what language or bindings you use.

So negative, you should brighten up a little.

I reckon anyone at university at that time would have been doing so. Sure, they were probably gopher URLs, but it is still a URL.
