c++ - Compiler memory consumption with template libraries (boost + Eigen) -

-

i writing template algorithm makes use of boost::accumulators , eigen linear algebra library. while compiling, visual studio compiler (cl.exe), memory consumption peaks @ on 2.5gb of ram, , pc (windows 7 32 bit 3gb virtual address space) becomes unresponsive (for quite long time: ~1 minute). binary files (.obj) 10-20mb these compilation units.

my questions (not directed towards these specific libraries)

  1. is normal behavior code heavily uses templates?
  2. is there can done reduce memory demands , compile time?
  3. if there no solution problem, why isn't addressed people design programming language? more people understand c++, more use templates, , generate hard-to compile code, , bloated binaries.

if there no solution problem, why isn't addressed people design programming language?

because there no solution, full stop.

the problem talking has nothing c++. it's artefact c- old "translation unit". fixing problem require re-doing compilation model. c++ committee has been trying years make happen without breaking every single line of existing c++ out there (which bigger consideration), it's not trivial problem. fixing require vast changes.

also, clang has way better performance, , newer versions of gcc variadic-template-equipped can well.

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
