Threading is required as there's processing going in the background. Not sure what you mean by non-blocking techniques. Lock-free algorithms maybe? These are used in ZeroMQ as well.

There are no 'scalability protocols' such as req/rep or pub/sub in libuv.

Never traversing the list. Removal every time a peer disconnects. Removal with intrusive containers: flip two pointers. Removal with std::vector<>: copy all the subsequent items in the vector one position backwards.

Ever tried removing element from a middle of vector?

Languages are designed for specific purposes. I am claiming that C++ is not the best language for system development. The fact that most OSes are not written in C++ is a good indication of the fact. Still, C++ is great for rapid development

Traditional message queues are actually composed of two rather different subsystem: the queue itself (basically a database) and the networking. I would say we are on the path of separating the two. ZeroMQ does away with the centralised serv

I've worked on OpenAMQ before ZeroMQ. And lots of proprietary stuff before that. So it would be more like dozenth-system syndrome :)

The trademark can be passed to a foundation so that it's not controlled by any particular company. However, even then, if you modify the code you should name it differently to prevent confusion.

Extra indirection is needed when the objects are non-assignable, e.g. if there's a thread running inside the object, if it owns a fd or similar. std::vector has O(n) complexity for a lot of operations, so it's not an option.

The above is a great post BTW. I recommend reading it.

Actually, the one-off nature of the thing may be very well what can makes this kind of charily work. If the donations were regular, a system of extracting the money (by usury, direct violence etc.) would quickly emerge.

Ack. Bur that's something you are not supposed to do in C. Not handling an exception within the function, on the other hand, is perfectly normal, if not encouraged, in C++.

How would you return the error from the private constructor to the static factory method?

Unless there's no catch block in the caller function. Then it starts to get messy.

It surprised me that Slovakia is among 10 most cyclist friendly countries. There's almost no infrastructure like bike lanes or bike stands and the country itself is mostly mountainous. Strange.

In many ways it resembles the story of Weimar republic and Hitler's ascension to power. There have been of lot of speculation about why that may have happened, what kind of social forces have made the population behave in a way that ul

Having observed corporate culture for quite a while, the most likely solution seems to be to fire the employee.

It's a TCP issue. When the other end of the connection goes away silently (power goes of, cable is cut off etc.) TCP doesn't inform ZeroMQ that the connection is broken, so ZeroMQ uses it furthe without trying to handle the error.

Absolutely true. Too late to fix now though.

Yes. Exactly. This is the least we can do in the Europe. There are at least 3 reasons to do so: 1. This way we can signal we mean it with the democracy thing. 2. We can prevent random despot to claim moral superiority to EU because of grant

It seems that everyone says yes. On the other hand, programming requires a pretty special way of thinking. Given that brain tends to be less malleable at 35 that it is at 18 it may be harder to catch up. Not undoable though.

Hm. His passport was revoked. Reminds me of the communist era here in eastern Europe when people were not allowed to hold passports, unless the state decided that it's safe to let them travel abroad.

Once I was renting an office of my own. Recently, I have moved to work from local library. I consider it 100% improvement in working conditions.

It really depends on the existing structure of the society. I guess that in, say, turn-of-century Sicily or present-day Somalia the money would pretty fast end in the hands of local crooks.

If it is a phone call, the company is spending money/time as well. It's mutual commitment. Developing test beforehand requires no commitment ($0) to particular applicant. There's no commitment. As for reviewing, I've seen A/B/C/D tests out
