... In concurrent computing, a deadlock is a state in which each member of a group of actions, is waiting for some other member to release a lock A livelock is similar to a deadlock, except that the states of the processes involved in the livelock constantly change with regard to one another, none pro...

...ution analyzers, branch predictors, Intel's "micro-ops fusion" that try to group instructions into larger batches of simultaneous work (kind of like the VLIW/Itanium titanic). There are even cache boundaries that could make the code run faster for god-knows-why if it's bigger (maybe the cache contro...

...rsion. Such versioned APIs should be time-limited and available to limited groups of API users (like during closed betas) only. Otherwise, you commit yourself where you shouldn't. A couple of thoughts regarding maintenance of API versions that have expiration date on them. All programming platforms...

...ns to be made from carbon and hydrogen, C8H8, and polystyrene is made from groups of that, (C8H8)n. Perhaps I should have stated that a polyp was many occurrences of the letter p although, now that I've had to explain the joke, even that doesn't seem funny either. Sometimes, you should just quit w...

...ch user like admin, guest_user, normal_user. The profiles are just logical grouping of permissions, independent of spring-security. When a new user is added, a profile is assigned to it (having all permissible permissions). Now when ever user try to perform some action, permission/role for that acti...

...ue that are compatible with C++98. We just divided the rvalues into two subgroups, xvalues and prvalues, and we refer to lvalues and xvalues as glvalues. Xvalues are a new kind of value category for unnamed rvalue references. Every expression is one of these three: lvalue, xvalue, prvalue. A Venn di...

... Mutexes have to remain globaly unique though. Depending on load scenarios group your frontend- and backend-servers by artifact-id ranges. This will allow for better usage of persistent memory (no database has all the data) and makes it possible to scale the mutexing. Your javascript has to maintain...

...as to deal with explicitly declaring/defining the copy constructor. I have grouped the cases into two categories Correctness/Semantics - if you don't provide a user-defined copy-constructor, programs using that type may fail to compile, or may work incorrectly. Optimization - providing a good alte...
