based on question "step over" when debugging multithreaded programs in visual studio , consider following scenario: thread running code starts thread b , keep going until point thread needs result of thread b. sake of sanity, let's assume following scheme: thread line 1 // <---- starts thread b line 2 line 3 // <---- breakpoint line 4 line 5 // <---- wait thread b thread b line 1 line 2 // <------ when code breaks, stoped here line 3 line 4 what happens when 1 click on "step over" button? i can think of 3 things: a go line 4. b stays in line 2 until "continue" button pressed. a go line 4. b go line 3 a go line 4. while don't stop @ line 4, b keeps going indefinitely. stop again, b stops. means b can in line 4 or exited while going line 3 4. if asked guess, i'd choose option 3. following line, there's way debug threads line line option 2? i'm asking in terms of there

i have client connected server via c berkeley sockets.

how inheritance of attribute classes work in c#? clarify, talking inheritance of attribute classes (i.e. base classes of system.attributes ), not classes happen have them attribute. for reason, cannot seem find on (my searches turn other meaning). for example, if have class attributea extends system.attribute : do have separately mark subclasses of attributea [attributeusage()] . (since system.attributeusage 's inheritance true , don't think will.) will allowmultiple=false on attributeusage of attributea prevent me having multiple subclasses of attributea attributes? edit: programmers can read code. [attributeusage(attributetargets.class, allowmultiple=false)] class attributea { } class attributeb : attributea { } class attributec : attributea { } [attributeb] [attributec] class foo { } does work? you can control behavior using named parameter inherited attributeusageattribute. [attributeusage(attributetargets.class, allowmultiple = fal

consider such rule in grammar lr-family parsing generator (e.g yacc, bison, etc.): nonterminal : [ lookahead not in {terminal1, ..., terminaln} ] rule ; it's ordinary rule, except has restriction: phrase produced rule cannot begin terminal1, ..., terminaln . (surely, rule can replaced set of usual rules, result in bigger grammar). can useful resolving conflicts. the question is, there modification of lr table construction algorithm accepts such restrictions? seems me such modification possible (like precedence relations). surely, can checked in runtime, mean compile-time check (a check performed while building parsing table, %prec , %left , %right , %nonassoc directives in yacc-compartible generators.) i don't see why shouldn't possible, don't see obvious reason why useful. have example in mind? the easiest way grammar transform mention in parentheses. make larger grammar, won't artificially increase number of lr states. the basic transfor

this question has answer here: how multiplication differ numpy matrix vs array classes? 7 answers in matrix multiplication, assume a 3 x 2 matrix (3 rows, 2 columns ) , b 2 x 4 matrix (2 rows, 4 columns ), if matrix c = * b , c should have 3 rows , 4 columns. why numpy not multiplication? when try following code error : valueerror: operands not broadcast shapes (3,2) (2,4) a = np.ones((3,2)) b = np.ones((2,4)) print a*b i try transposing , b , alwasy same answer. why? how do matrix multiplication in case? the * operator numpy arrays element wise multiplication (similar hadamard product arrays of same dimension), not matrix multiply. for example: >>> array([[0], [1], [2]]) >>> b array([0, 1, 2]) >>> a*b array([[0, 0, 0], [0, 1, 2], [0, 2, 4]]) for matrix multiply numpy arrays: >>

i have web api , added web api pages auto-generate documentation. it's working great methods parameters listed out, have method this: public sessionresult postlogin(createsessioncommand request) and, on page, listing command parameter in properties section. however, in sample request section, lists out of properties of createsessioncommand class. parameters name | description | additional information request | no documentation available. | define parameter in request body. i instead list of properties in createsessioncommand class. there easy way this? this should go addition @josh answer. if want not list properties model class, include documentation each property, areas/helppage/xmldocumentationprovider.cs file should modified follows: public virtual string getdocumentation(httpparameterdescriptor parameterdescriptor) { reflectedhttpparameterdescriptor reflectedparameterdescriptor = parameterdescriptor reflectedhttpparameterdescri

currently i'm using paintobject.measuretext(textcopy.substring(0,i)) while iterating through copy of textview's text. example, measuretext("abc".substring(0,1)) give me relative x coordinates of 'b'. y coordinate layout.getlinetop() . working not accurate x coordinates non-monospaced fonts. can calibrate little, on each device works differently. the best solution can think of overwrite class responsible drawing textview on screen and, hopefully, coordinates of each character drawn screen. does know class need overwrite accomplish this? or maybe other creative solution? well seems sort of bug of paint.measuretext() or other deeper class. have finally found way around it: layout.getprimaryhorizontal(int offset) this easy. iterate through layout using length of text uses. it return the x of character regardless of line position. lines i'm still getting layout.getlinetop() . way, if using layout.getlinetop() , note there strange
