blocks|key|4881858|text|对我来说，这就是线程。即使是相对“简单”的线程也是具有挑战性的，如果您深入研究无锁代码的领域，它会变得更加棘手。当然，有一些线程范例不会引起很多令人头疼的问题(参与者、消息传递等)，但它们往往会有自己的权衡。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4881859|在我看来，这是一种“深度”的复杂性，但编码的其他领域以不同的方式具有挑战性。安全性、i18n和日期/时间处理(或者几乎任何与实际人类特征相关的东西)都非常挑剔，有很多需要学习和注意的角落案例。这当然很难，但是以一种不同的方式来实现并发。|4881860|编辑:作为对twk答案的回应:是的，有很多人试图让并发变得更容易。虽然已经有各种平台很好地支持并发性(例如Erlang)，但目前更多的是将更简单的并发性带到已经主流的平台。从我作为一名.NET开发人员(好吧，不管怎样，是一个业余/狂热的.NET开发人员；目前是专业的Java开发人员)的角度来看，Parallel+Extensions和Coordination+and+Concurrency+Runtime是最近最有趣的两个开发。我并不期望这会让并发变得容易--只是对凡人来说是可行的。|offset|length|4881861|entityMap|0|LINK|mutability|MUTABLE|url|http://blogs.msdn.com/pfxteam/|1|http://en.wikipedia.org/wiki/Concurrency_and_Coordination_Runtime^0|0|0|44|J|0|4O|10|1|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$F|U|G|V|1|W]|$F|X|G|Y|1|Z]]|A|$]]|$1|H|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]|P|$5|K|L|M|A|$N|Q]]]]

For me, it's threading. Even relatively "simple" threading is challenging, and if you delve into the realms of lock-free code it gets even hairier. There are certainly threading paradigms which don't raise as many mental headaches (actors, message passing etc) but they tend to come with their own trade-offs.

This is a level of "deep" complexity in my view, but there are other areas of coding which are challenging in different ways. Security, i18n and date/time handling (or pretty much anything related to actual human characteristics) is very finicky, with lots of corner cases to learn and watch out for. This is certainly hard, but in a different way to concurrency.

EDIT: As a response to twk's answer: yes, there are lots of people trying to make concurrency easier. While there are already various platforms which support concurrency well (e.g. Erlang) there's more of a move at the moment to bring simpler concurrency to already-mainstream platforms. From my point of view as a .NET developer (well, an amateur/enthusiast .NET developer anyway; professionally Java at the moment) the <a href="http://blogs.msdn.com/pfxteam/" rel="nofollow noreferrer">Parallel Extensions</a> and <a href="http://en.wikipedia.org/wiki/Concurrency_and_Coordination_Runtime" rel="nofollow noreferrer">Coordination and Concurrency Runtime</a> are the two most interesting recent developments. I don't expect this to make concurrency easy - just feasible for mortals.

blocks|key|1097217|text|我同意Jon+Skeet的观点，线程/并行执行是一个热门话题，有一些新的领域，或者正在思考开箱即用的技术，比如Transactional+Memory。这是一个新概念的开放领域。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1097218|entityMap|0|LINK|mutability|MUTABLE|url|http://research.sun.com/spotlight/2007/2007-08-13_transactional_memory.html^0|1J|K|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I concur with Jon Skeet that threading/parallel execution is a hot topic and there are opening new fields, or thinking out-of-the-box technologies, like <a href="http://research.sun.com/spotlight/2007/2007-08-13_transactional_memory.html" rel="nofollow noreferrer">Transactional Memory</a>.

I sure hope there are some people out there busy making it easy to use more processor cores automatically. Sure, there is stuff like the Intel Thread Building Blocks or even languages like Erlang, but I hope we see a lot more progress on that front in the next 10 years.

blocks|key|1150297|text|至少在本地，热门领域是informatics，特别是生物信息学。从许多来源收集、组合、关联和分析信息，并从收集的信息中获得额外的信息，这代表了计算机科学与其他活动之间最紧密的联系。这是我们CS系提供的最新学位，吸引了来自许多学科的最多研究生进入CS课程。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1150298|我不知道它在精神上有多大的挑战性，但作为一个新的想法，有很多想法都没有被考虑过，更不用说调查了。提出原创想法是相当具有挑战性的，尽管它们背后的实际编程部分可能不是。|1150299|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Informatics^0|B|B|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

At least locally, the hot field is <a href="http://en.wikipedia.org/wiki/Informatics" rel="nofollow noreferrer">informatics</a>, especially bioinformatics. Collecting, assembling, associating, and analyzing information from many sources and deriving additional information from the collection represents the strongest connection of computer science to other activities. It's the newest degree that's offered our CS department and is drawing the most graduate students, from many disciplines, into CS classes.

I don't know how mentally challenging it is, but being new there are a lot of ideas out there that haven't been thought of, let alone investigated. Coming up with original ideas is pretty challenging, though the actual programming part behind them probably isn't.

What represents the most mentally challenging form of coding? Embedded firmware development.

Right now, many talented people in my area are headed towards nanotechnology.

What is the equivalent field in modern computer science? Again, Embedded firmware development.

And for any desktop or internet developers, if you don't think embedded coding is far more difficult than any other type of coding then you don't know embedded. I can do anything a desktop or internet programmer can do, but it's very doubtful that most, if any, desktop/internet programmers can do embedded well, or at all.

Case in point, I've got a bug I'm working on right now where after 4 bytes are received successfully on a serial communications port (interrupt driven reception) successive bytes don't cause the UART to generate an interrupt (as they should).

So, Windows and Internet programmers - what would you consider the most likely causes? What would you do? Oh, I forgot, Windows and Internet programmers don't have full and direct access to the hardware - so they've probably never even experienced such a situation. In the embedded development world you can't say "it's the hardware" and leave it at that - you are responsible to make it work by yourself, all the way from the UI down to the power supply (software, firmware, hardware, it's all the responsibility of the embedded developer). This is a greater challenge than any Windows or Internet programmer can encounter.

blocks|key|1097298|text|对我来说，很难说出最具脑力挑战的是什么:我不认为有一个。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1097299|系统和嵌入式编程是两个最难的领域。你离硬件越近，就越难(在你的生活中至少看一次real+mode+assembly+:D)。|offset|length|1097300|Jon说并发编程非常棘手，而且很难做到正确，这是完全正确的。|1097301|但我会对密码，或机器学习，或数学编程的某些方面得出同样的结论。我想区分CS基础和更高层次的任务是有意义的。|1097302|不过，这是一个非常主观的问题。|1097303|entityMap|0|LINK|mutability|MUTABLE|url|http://wiki.osdev.org/Real_Mode^0|0|13|I|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@]|9|@$D|V|E|W|1|X]]|A|$]]|$1|F|3|G|5|6|7|Y|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|Z|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|10|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S]]]]

To me it's very difficult to name the most mentally challenging: I don't think there's a single one.

System and embedded programming are two of the hardest areas IMHO. The closest you get to the hardware, the hardest (take a look at <a href="http://wiki.osdev.org/Real_Mode" rel="nofollow">real mode assembly</a> at least once in your life :D). 

Jon is absolutely right then to say that concurrent programming is very tricky, and hard to get right.

But I would conclude the same about some aspects of crypto, or machine learning, or math programming. I guess it makes sense to distinguish between CS fundamentals and higher level tasks... 

Very subjective question, though.

I am pursuing a graduate degree in Organic Chemistry.

Right now, many talented people in my area are headed towards nanotechnology.
