i'm having trouble calculating used memory (resident) set of processes. the issue came user set of processes share memory between themselves, simple addition of used memory ends nonsense number (>60gb when machine has 48gb memory). is there simple way approach problem? i can approximation. take (res mem - shared mem) * num proc + shared mem . not processes share same memory block. i'm looking posix or linux solution problem c/c++. you want iterate through each processes /proc/[pid]/smaps it contain entry each vm mapping of likes: 7ffffffe7000-7ffffffff000 rw-p 00000000 00:00 0 [stack] size: 100 kb rss: 20 kb pss: 20 kb shared_clean: 0 kb shared_dirty: 0 kb private_clean: 0 kb private_dirty: 20 kb referenced: 20 kb anonymous: 20 kb anonhugepages: 0 kb swap: 0 kb kernelpagesize: 4 kb mmupagesize

i discovered have duplicate pages need remove pages should not exist indexed , generating small amounts of traffic. want redirect urls original ones. http://www.example.com/buy-something.php to http://www.example.com/something.php i need remove "buy-" in urls , make sure page redirected proper page. here have far: #301 redirect buy- none rewriterule ^([a-za-z\.]+).php$ /buy-$1.php [l,r=301] but nothing pages should redirected , adds loop of buy-buy-buy-buy-buy-buy- other pages , causes them time out. have tried few other variations no prevail. your appreciated. you mixed syntax, right redirecting .php /buy- .php, since want other way arround try: redirectrule ^buy-([a-za-z\.]+).php$ /$1.php [l,r=301] that should take buy-*.php domains , redirect them *.php code 301. source: http://httpd.apache.org/docs/current/mod/mod_rewrite.html

i title wasn't best don't quite know how explain it. tkinter want make square widgets "slots on them. when app run want buttons show @ top of screen , 4x4 grid of square widgets. app wait user click on button. button should move top left slot on top left square. after done user should repeat process , next button should go next slot on top left square , on until square full, repeat process next square. should fixed position button allows me pass on slot without putting things in it? how should accomplish this? have loop need: elem in zip(*l): in elem: print(a) i'm not entirely sure if understand problem correctly, looks @ core, you're trying reposition tkinter widgets, correct? you can geometry manager. if use grid method (which in case recommend) can do: def changebuttonpostion(): button2.grid_remove() #gets rid of widget in top left corner button.grid(row=0, column=1) #the top left corner of 4x4 grid otherwise, can use p

if have uiview instance variable add view subview; does calling removefromsuperview dealloc instance variable when using arc? or can add again different view? if have strong pointer view you're adding/removing, calling removefromsupeview not cause object deallocated. can have strong pointer either declaring uiview ivar, or declaring strong property (preferred). however, if have no other strong pointer view, deallocated arc if remove superview. (the superview keeping strong pointer, , breaking connection.)

so let's in service oriented architecture, have 3 layers: the web/external layer - user sees application logic - generates layer 3. handles users, sessions, forms & etc... internal api - data, , how access data now 1 , 2 live in same network latency our least thought of problem. essentially, layer 2 consumes data layer 1 using rest. thinking of alternatives how data can consumed. what pros , cons of making layer 1 , 2 communicate websockets instead of rest? assuming, have multiple servers , layer 2 applications. this question purely out of curiosity. there old discussion on restfull http vs websockets. think of them being different. in general, websockets give finer control. comes perhaps more efficiency --imagine if you, say, define own protocol. downside have less standard approach. rest less flexible more standard , more loosely coupled. stefan tilkov summarized pretty in blog post . there related discussion here .

my app displays prices reported getskudetails() api. confirm working i'd setup device display prices different locales. i've tried logging in google accounts different countries , setting system language prices still appear in own locale. how can setup device can see prices reported in different locales? i guess that's not easy. in case experienced same issue. according information read, looks there several procedures google uses locate user. 1 of them consist of check procedence of credit card registered in google play, if users has one. if case, shown prices of locale corresponding credit card. second check, made thru sim card of mobile phone. if don't have sim card or device tablet without sim card, next step looking wifi connection. localization of wifi spot, , ipaddress, used geolocate user. finally if nothing of works, locale settings in device used. in way, google show prices according place are, couldn't match locale settings in device.

when work on algorithm solve computing problem, experience speed can increased using more memory, , memory usage can decreased @ price of increased running time, but can never force product of running time , consumed memory below palpable limit . formally similar heisenberg's uncertainty principle: product of uncertainty in position , uncertainty in momentum of particle cannot less given threshold. is there theorem of computer science, asserts same thing? guess should possible derive similar theory of turing machines. i not familiar description of parallels heisenberg's uncertainty principle, per se , sounds me closely related computational complexity theory . problems can classified according inherent, irreducible complexity, , think that's you're getting @ limit of "the product of running time , consumed memory".

is there anyway create same plot twice saving type of axis handle? my plotting code creates special symbols each point in scatter plot. want create figure 2 subplots. first plot want set specific part of axis (0 10), second plot want (90:100). know recreate plot copy , pasting code, seems cumbersome , hassle manage if change else plots. is there anyway can create plot once, save handle , replot it? here functionality looking for: figure; hold on; x = [1 10 20 10 2000 3000]; y = [10 30 40 20 100 200 ]; // create plot 1 point @ time = 1:4 subplot(2,1,1); plot(x(i),y(i),'r'); // redacted code // there bunch of code here adjust of first plot each point // in order define of each marker in scatter plot, // has done 1 point @ time // redacted code end // adjust axis axis([1 60 0 50]); // figure handle handle = gcf; // create second plot same characteristics first plot different axis boundaries subplot(2,1,2); plot(handle); axis([90 250 1000 4000]);

im working on review sheet pretty got except not sure these two. please? q benefit of using queue merge sort? q suppose in mergesort replace queue stack (i.e. push instead of enqueue, pop in place of dequeue). explain effect replacement have. with queues things automatically added end of list; thus, when lowest level of mergesort 's recursion (individual elements), sorted array can enqueue largest of these elements new list. using stack should reverse list since elements added put @ front, you'd have search smallest element instead of largest.

i beginner rails , appreciate guidance! here link_to in first view: <%= link_to micropost.user.name, micropost.user %> | <%= link_to "send message", new_conversation_path( target: micropost.user.name, reason: micropost.c1 ) %> and here conversations controller: def new @target = params[:target] @reason = params[:reason] end def create recipient_names = conversation_params(:recipients).split(',') recipients = user.where(name: recipient_names).all conversation = current_user. send_message(recipients, *conversation_params(:body, :subject)).conversation redirect_to conversation end as can see, i'm using mailboxer gem not have conversation model. finally, here form in second view: <%= simple_form_for :conversation, url: :conversations |f| %> <%= f.input :recipients, @target %> <%= f.input :subject, @reason %> <%= f.input :body %> <div class="form-actions">

i have c++ classes in following format (copying important parts): class my_stringimpl { public: static sample_string* create(const char* str, int len) { my_stringimpl* sample = static_cast<my_stringimpl*>(malloc(sizeof(my_stringimpl) + len*sizeof(char))); char* data_ptr = reinterpret_cast<char*>(sample+1); memset(data_ptr, 0, len); memcpy(data_ptr, str, len); return new (sample) my_stringimpl(len); } private: int m_length; }; class my_string { public: my_string(const char* str, int len) : m_impl(my_stringimpl::create(str, len)) { } ~my_string() { delete m_impl; } private: my_stringimpl* m_impl; }; for my_string class adding pretty printer. added following defs in python script (which including in .gdbinit file) - func defs copied here: def string_to_char(ptr, length=none): error_message = '' if length none: length = int(0) error_message = 'null string' else:

could give explain on following example code? it's last example here . not sure why there's no '\' before '.' , can same result adding '\' . javascript: var url = "http://xxx.domain.com"; print(/[^.]+/.exec(url)[0].substr(7)); // prints "xxx" note paragraph here regarding metacharacters inside character classes note special characters or metacharacters inside character class closing bracket (]), backslash (\), caret (^) , hyphen (-). usual metacharacters normal characters inside character class, , not need escaped backslash.

in 8086 more 1 logical addresses (segment:offset) can have same physical address (001f:000f , 000f:010f same address ,like 001f:000f = 01f0+000f = 01ff in same way 000f:010f = 01ff).in physical memory ,any program sees logical memory address.so more 1 program can have data (byte) same physical address (though logical addresses different) position.why don't collide each other ? why don't lose data ??? the 8086 can address 1mb of memory, requiring 20 bits specify address of particular byte. since 8086's registers hold 16 bits, segment model developed gives each of 1m addresses many different names. number 4 can named 0+4 , 1+3 , 2+2 , etc., address 12345 can expressed 1234:0005 , 1233:0015 , 1230:0045 , , on. in other words, each physical address has 64k different logical addresses. means if 1 program accessing 1234:0005 , program accessing 1233:0015 , 2 programs accessing exact same memory address. so how prevent different programs "colliding"

i have drag , drop code need switch content in drag , drop. when drop tr on tr append new tr want these 2 tr should change position instead of append it. not interested in plugin , if can done using jquery gr8. html code: <table> <tr> <td id="tblrw1" draggable="true" ondragstart="drag(event)" ondrop="drop(event)" ondragover="allowdrop(event)"> dummy text1 </td> </tr> <tr> <td id="tblrw2" draggable="true" ondragstart="drag(event)" ondrop="drop(event)" ondragover="allowdrop(event)"> dummy text2 </td> </tr> <tr> <td id="tblrw3" draggable="true" ondragstart="drag(event)" ondrop="drop(event)" ondragover="allowdrop(event)"> dummy text3 </td> &

i trying write lighting code java2d isometric game writing - have found few algorithms want try implementing - 1 of found here: here the problem sort of algorithm require optimal pixel-shading effect haven't found way of achieving via java2d. preferably method via graphics hardware if isn't possible - @ least method of achieving same effect in software. if isn't possible, direct me more optimal algorithm java2d in mind? have considered per-tile lighting - find drawpolygon method isn't hardware accelerated , performs slowly. i want try , avoid native dependencies or requirement elevated permissions in applet. thanks i did lot of research since posted question - there tons of alternatives , javafx intend (on later release) include own shader language interested. there ofcourse lwjgl allow load own shaders onto gpu. however, if you're stuck in java2d (as am) still possible implement lighting in isometric game 'awkward' because cannot pe
