malloc is usually a bad idea in C++. If you must dynamically allocate, and I'm not sure you do, consider using new instead. That being said, Why should C++ programmers minimize use of 'new'? — user4581301 24 secs ago

Wrong site, I'm afraid. You're looking for Super User instead. This site is for specific questions related to programming (code) or use of programmers tools. You can find more information about this site by taking the tour and reading the help center pages. — Ken White 45 secs ago

I am voting to reopen. Programmers use indexes more often than database administrators, there's no point in moving the question to another site. And while the premise of this question is wrong (as William Robertson pointed out, queries can use many b-tree indexes), it can still be a good question. I bet there is some misunderstanding about how bitmap indexes can be combined in more ways than b-tree indexes. While bitmaps can be easily ANDed and ORed, b-tree indexes can still be combined in many interesting ways in the same query. — Jon Heller 19 secs ago

1) I was not aware of softwarerecs, I will attempt to use it in the future 2) Huge thanks for your code/NPEET, it will save me a lot of time 3) Read the Bengio paper, also big fan, but in this case I am somewhat cautious. The method effectively uses a neural network as a density estimator, which should still have the same regularizing challenges as, e.g. KDE. Namely, the best density estimator is a bunch of dirac delta functions, which is obviously wrong. 4) As you mentioned, continuous data is indeed crucial, so discrete methods are of limited interest. — Aleksejs Fomins 39 secs ago

This question is on-topic here, but I think you'd get a much more useful response if you posted on Cross Validated. Making dense numerical information into understandable graphics is difficult, and, ah, not something that programmers excel at. If you'd like the question migrated, click the "flag" link and select "in need of moderator intervention". — Sneftel 38 secs ago

While questions about "software tools commonly used by programmers" are on-topic this is still way too broad and definitely opinion based. -- that said, you don't need much... a simple editor and compiler should do. But if you want to be productive, you probably want an IDE like Visual Studio. Anything else would depend heavily on the area you want to work in. For example, if you want to work with databases, you probably want to know about Entity Framework. — Corak 39 secs ago

@ThomasMorris Ignore the down-voting of the answer. The answer is correct. Usually such answers are down-voted by low-qualified programmers.:) — Vlad from Moscow 54 secs ago

@zero298 "... unless management doesn't understand and wants blind strict adherence": Exactly this. The management hires no programmers but code writers (or copy/paste guys) because it then relies on such tools that then will "improve" the badly written code. — Axel Richter 46 secs ago

This site is for specific questions related to programming (code) or use of programmers tools (IDEs, compilers, etc.). It's not for collecting lists, taking surveys or polls, or other such uses. You'll find your experiences here will be much better if you spend some time taking the tour and reading the help center pages to learn how the site works before you begin posting. — Ken White 49 secs ago

@Ctx, OK, that's fine, but it is that type of misguided thinking that has led to giant security holes in network applications. Remind me to never hire you for anything like that. We have had programmers who could not wrap their heads around the idea that servers could initiate the connections, and they are gone because out security servers must initiate the connections with the clients because compromised clients may not initiate the connection, and if a client refuses the connection, it is blocked from the network and wiped. — Ron Maupin 15 secs ago

If a fool is upset by others believing that they're foolish, that's outside of my control. We are programmers/scripters, and only a foolish one would believe that creating a solution to format the file content resulting from your inefficient, and frankly crazy, sequence of commands is worthwhile. An non-foolish solution is to take a step back, look at the entire task and build a more robust and/or efficient solution from the ground up. — Compo 32 secs ago

@Sahsahae the lack of consistency is barely an issue. In fact, the style is personal choice There's actually quite a bit of academic research over decades showing the opposite: "the level of identation had a significant effect on program comprehension" That's from 1983, so the ideas are hardly new. Have you ever worked on a project that literally had over a hundred programmers? There's also a lot of research that human minds recognize familiar patterns much faster and more accurately. — Andrew Henle 59 secs ago

Glad it helped. That is what makes this site so special. It is a wonderful vehicle to hand learning down to the next generation of programmers and engineers. Good luck with your coding :) — David Rankin - ReinstateMonica 34 secs ago
