Matlab is a Numerical Computation System, not a Computer Algebra System
In a 1943 letter Einstein said he made a statement "which corresponds approximately" with Time article, but that it was made much earlier than 1940 "during the first years of the Nazi regime" and that his actual comments were "more moderate." In a 1950 letter Einstein said that his quoted remarks from the Time article were "not my own", that they had been "elaborated and exaggerated nearly beyond recognition" and that he was "predominantly critical" of the clergy. In a 1943 interview Einstein was extremely critical of the Catholic Church's behavior under the Nazis, and also singled out Pope Pius XII for criticism because of his Concordat with Hitler, saying "Since when can one make a pact with Christ and Satan at the same time?"
had to go elsewhere when kde3 became impractical to keep running and kde4 was completely broken.
When was this? When did KDE3 become impractical and why and what was the available KDE4 version at the time?
Your b is a constant pointer, you can't do b = a. If you, with your whole experience, managed to mess that up, imagine an 11 year old.
And then throw in the added energy required by an air conditioner to remove all that heat from your house.
To be fair, if you really think this actually makes a difference, you also should factor out decreased costs in heating for those in cold places.
Manage List -> Choose update types. It is actually quite fine grained, you can disable all kinds of updates, or keep just some of them. You can also do it individually for each friend. In the individual settings you can also choose to get all updates, most, or none.
You can also use lists to control exactly who can chat with you. Can you do that with G+ circles? Are you sure? What about those who were in your chat before G+ existed? You have dynamic lists on FB with friends in your city, those from your work, from your University, etc. Any automatically generated circles in G+? You can use FB lists to invite people to events. Any integration of G+ circles with your calendar?
Because it's terribly implemented. Hell, lists on facebook now offer better functionality then google circles with things like smartlists. In facebook I use lists to control who I chat with, how about in G+? Yes I can select the circles who are allowed to talk to me, but what about those who I had before G+? They are in the same chat, so how do I manage them? Integration of Google calendar with G+? Oh G+ is not for that, it's not meant for you to actually manage your social life... well then I still need facebook don't I, and in that case why should I bother with both? And I could go on and on...
Could you expand on this? I don't work that much with OO languages. So I looked for 'Liskov substitution principle' and I understand it concerns semantic requirements of types in a hierarchy. But aren't these semantic requirements valuable precisely so that your code behaves uniformly across types, and is therefore reusable?
