is possible replace file in zip file without unzipping deleting old file adding new file , rezipping back? reason have zip file big there 1 xml inside zip file have update sometimes. unzipping zip , rezipping takes long time. i'd able replace 1 xml inside zip through script. have checks updates on xml have. so possible replace 1 xml without unzipping , rezipping ? sorry use zip command things problem script android phone , zip not command can use unfortunately sorry left out. have used zip definately if have unzip droid , there tar in busybox tar doesn't need from zip(1) : when given name of existing zip archive, zip replace identically named entries in zip archive or add entries new names. so use zip command create new .zip file containing 1 file, except .zip filename specify existing archive.

i need write c# application calling command line tool (probably written in c), of know it's unstable. wonder if it's possible catch random crashes of tool in application. it enough handle these crashes terminating app , writing log message indicating tool has crashed. this how call (details process.startinfo settings omitted): process exeprocess = new process(); exeprocess.start(); exeprocess.waitforexit(); exeprocess.close(); i can reproduce 1 particular kind of crash due bad input data (c0000005 access violation exception), check preconditions before starting process. i'm sure in production other kinds of crashes occur. there's not whole lot predictable process crashes violently. if due hardware exception, accessviolation, there reasonable odds process exit code indicator. use process.exitcode after waitforexit() read it. value of 0 indicates success, although that's app well.

background: i'm developing game iphone/ipad using cocos2d-iphone. our engine provides ability level designer create new bad-guys defining number of properties such speed, ai, weapons , main sprite texture in .plist files. problem: currently, build nsdictionary of of prototypes before level starts. each entity store class name , nsdictionary describing parameters required build new instance of entity. create instance of each prototype @ load time precache textures destroy immediately. when new bad guy spawns, use stored nsdictionary , pass init method (stripped of error checking brevity); ikprototype* prototype = [prototypes objectforkey:prototypeid]; ikbaseentity* entity = [[[nsclassfromstring([prototype prototypeclass]) alloc] init] autorelease]; [entity setprototypeid:prototypeid]; [entity parseparameters:[prototype parameters]]; return entity; now, works treat - creating number of bullets in same frame causes noticeable slow down (a frame or 2 dropped) engine parses...

i trying set mediacore (which pylons app) on production server. docs suggest either apache mod_fastcgi or mod_wsgi webserver try avoid apache @ cost because of being ram-monger. on other hand mediacore works fine when use paster, wondering pros/cons of ignoring apache , use paster production web server? as load grows, may hit cpu or db limit. typical answer using several parallel backends. nginx or lighttpd or whatever light http server come in handy , allow distribute load several paster servers , serve static files cheaply. up until you're safe run paster, if have excess cpu waste on serving static files.

i wrote command line tool in java , gets run many times in row bat script. right it's runnable jar (which in hindsight isn't right choice here...). jre seems loaded , unloaded every time program run, seems inefficient. overall, seems lot slower should be. do java gurus out there know more proper way handle situation? as there no easy fix, might consider more radical approaches: actually porting what's in bat in java (easy if it's loop on files kind of filter). compiling jar exe (e.g. gcj) if maximum portability not issue.

i'm trying parse date/time string in custom format using boost's date time library. format i'm trying use rather unusual because includes posix time zone description string. docs library clearly state there flag ( %zp ) usable both input , output handles posix time zone string. value i'm trying parse coming web browser, , rather write js perform transformation specified in zone string , send server in utc, i'd rather server-side (since boost should easily). wouldn't posting here if worked. code throws boost::bad_lexical_cast value of "source type value not interpreted target". using namespace boost::posix_time; using namespace boost::local_time; using namespace boost::gregorian; std::istringstream ss("1989-11-09t15:30:42.005;pst-8pdt,m3.2.0,m11.1.0"); ss.exceptions(std::ios_base::failbit); local_time_input_facet* facet = new local_time_input_facet("%y-%m-%dt%h:%m:%s%f;%zp"); ss.imbue(std::locale(ss.getloc(), facet)); ...

is there standard way so? in short: no, because json doesn't have primitive ordered map type. the first step determine requirements of client, far decoding json string goes. since json specification doesn't have ordered map type, you'll have decide on representation use. choice make depend on decoding requirements of client. if have full control on decoding of json string, can encode object map in order, using json library guaranteed serialize things in order of iterator pass in. if can't guarantee this, should come representation on own. 2 simple examples are: an alternating list: "[key1, value1, key2, value2]" a list of key/value entry objects: "[{key: key1, val:value1}, {key: key2, val:value2}]" once you've come representation, it's easy write simple function loops on simpleorderedmap. example : jsonarray jarray = new jsonarray(); for(map.entry e : simpleorderedmap) { jarray.put(e.key()); jarray.pu...

i have 2 models attackreport , attackreportround. each report can have many rounds. describes how attack made. how have designed wanted @ first. however, if attack has, 30 rounds, attackreportround table can become way big. therefore, thinking of way store in single row if possible, or in efficient way. attack round keeps information attacker hit, damage, defender health , stuff that. i thinking of serializing data every round in single attackreport entry, maybe using comma separated values or sort of rails serialization. what in case ? database tables can hold lot of rows before performing badly, if using indices properly. have considered 'archiving' old attackreport , attackreportround entries in other tables? assuming attackreport year ago isn't queried -- depends on app doing. if go serialization, i'd use built-in rails 1 (it serializes yaml , requires little coding on part) before doing own csv solution.

is there way track variable changes or memory changes in xcode? i'm looking functionality visual studio's data breakpoint. i want know object's view frame being changed. want set breakpoint @ member variable , run it. determine it's changed. xcode uses gdb (or lldb , that's story) implement debugging functionality. gdb has ability set hardware watchpoints , hence xcode. this useful page generic debugging of memory errors. xcode's debugging console window gdb shell, can type in commands please. ever-helpful quinn taylor explains how in this related post. if you'd rather avoid interacting gdb directly, can right-click variable in xcode's debugging window , select "watch variable". xcode alert whenever variable's value has been changed.

i've got dict: text_to_count = { "text1": 1, "text2":0, "text3":2} i'd create list of formatted strings sorting dict's values (in descending order). i.e., following list: result = ["2 - text3", "1 - text1", "0 - text2"] any ideas? edit: while waiting responses, kept hacking @ , came with: result = map(lambda x: "{!s} - {!s}".format(x[1], x[0]), sorted(text_to_count.iteritems(), key = lambda(k, v): (v, k), reverse=true )) tho i'm still interested in seeing other solutions there are, possibly 1 better. how's this? result = ['{1} - {0}'.format(*pair) pair in sorted(text_to_count.iteritems(), key = lambda (_,v): v, reverse = true)]
