i've got makefile has couple of targets (all, install, uninstall). i'm trying use $java_home environment variable, works perfect in target, when install target executed, $java_home variable seems empty (although not - have checked in terminal). have ideas? all: # works @echo ${java_home} ifeq ($(uname), linux) install: # prints blank line. @echo ${java_home} # doing stuff here uninstall: # doing stuff here endif thanks, chris i don't see problem have posted, way set java_home before calling make may contributing factor. using export create environment variable? if not, make process might not inheriting part of environment.

i read using flexible array members in c poor software engineering practice. however, statement not backed argument. accepted fact? ( flexible array members c feature introduced in c99 whereby 1 can declare last element array of unspecified size. example: ) struct header { size_t len; unsigned char data[]; }; the reason give not doing it's not worth tie code c99 use feature. the point can use following idiom: struct header { size_t len; unsigned char data[1]; }; that portable. can take 1 account when allocating memory n elements in array data : ptr = malloc(sizeof(struct header) + (n-1)); if have c99 requirement build code other reason or target specific compiler, see no harm.

i've read somewhere (can't remember/find where) article web usability describing when use drop downs , when use autocomplete fields. basically, article says human brain cannot store more last 5 options presented choose. for example, in profile form, there current occupation, , system gives bunch of options, when read sixth options, brain can't remember first 1 anymore. example great place use autocomplete field, user types thinks occupation , select better few options filtered. i hear opinion subject. when should use drop-down , when should use autocomplete field? for limited list, don't use autocomplete edit box or combobox, use listbox values visible @ once. limited lists, static content of 8 items, takes real estate, presents user better immediate overview. for less 5 items radiogroup or checkbox group (multiple selections) may better. for lists content dynamic, list of contacts, (scrolling) listbox or combobox appropriate because never know ...

facebook doing ajax history (back , forward button) , bookmark using #! instead of # in url. idea that, because thinking usual anchor interfere ajax history mechanism trigger processing normal anchor. so, ajax history function process hash portion when sees #! instead of # . and using ! compatible major browsers? if facebook using ! , guess may supported. see google's making ajax applications crawlable possible use case (don't know if why facebook used fragment).

on msvc++ compiler, 1 can use __int8 , __int16 , __int32 , similar types integers specific sizes. extremely useful applications need work low-level data structures custom file formats, hardware control data structures , like. is there similar equivalent can use on gcc compiler? iso standard c, starting c99 standard, adds standard header <stdint.h> defines these: uint8_t - unsigned 8 bit int8_t - signed 8 bit uint16_t - unsigned 16 bit int16_t - signed 16 bit uint32_t - unsigned 32 bit int32_t - signed 32 bit uint64_t - unsigned 64 bit int64_t - signed 64 bit i use these types time. these types defined if implementation supports predefined types appropriate sizes , characteristics (which do). <stdint.h> defines types names of form (u)int_leastn_t (types have at least specified width) , (u)int_fastn_t (the "fastest" types have @ least specified width); these types mandatory. if you're using old implementation doesn't supp...

j2me lacks java.util.properties class. although possible put application settings in jad file not recommended many properties. (since, platforms limits size of jad file.) want put configuration file inside jar file , parse it. , not want go xml because overshooting case. question is, there existing library j2me can parse properties files or similar such ini file. or recommend method solve initial problem? the best solution depends on going generating properties files. if you've got other non-javame projects using same properties files, stick them, , write or find parser. (there a simple 1 gobible available on google code ) however might find easy keep configuration static final string myproperty="myvalue"; in configuration.java file compile, , include in jar instead, since not need special code locate, open, read, , parse them. you pick limitation on call them though, since can no longer use common dot separated namespacing idiom.

we have had issues mootools not being backward compatible in area of drag , drop functionality. wondering if has had similar problems jquery not being backward compatible. starting use quite heavily , thinking upgrading newer version start using several plugins require it. have issues if rid of older version? jquery seems nicely backward compatible. have been using more couple of years through several versions of core , have not had issues when upgrading except few minor ones plugins. core seems fine if you're using lot of plugins might run problems (but these easy fix, or new core has functionality built in anyway can drop them).

i have first dialog simple button on , while clicking button, second dialog created using cdialog::create(idd,this). parent notified when second dialog destroyed without adding code second dialog i.e., without adding m_pparent->notify() line in ondestroy method. have tried onparentnotify, pretranslatemessage, subclasswindow in parent dialog no success. have not used ws_child style second dialog. idea? to complete: in fact, have combobox derived class (but issue same buttons) , i'm displaying modeless dialog instead of displaying listbox. control generic possible modeless dialog used. that's why not want add specific notification in second dialog. if i'm obliged, use trick asked more generic solution. pretranslatemessage catches wm_paint, wm_ncmouseleave , wm_ncmousemove. use base class , have parent refer modeless child base class only. in base postncdestroy have post parent. it doesn't make sense have parent bunch of filtering / spying on messages. ...

normalization leads many essential , desirable characteristics, including aesthetic pleasure. besides theoretically "correct". in context, denormalization applied compromise, correction achieve performance. there reason other performance database denormalized? the 2 common reasons denormalize are: performance ignorance the former should verified profiling, while latter should corrected rolled-up newspaper ;-) i better mantra "normalize correctness, denormalize speed - , when necessary"

i'm writing simple program that's going parse logfile of packet dump wireshark more readable form. i'm doing python. currently i'm stuck on part: for in range(len(linelist)): if '### server' in linelist[i]: #do server parsing stuff packet = linelist[i:find("\n\n", i, len(linelist))] linelist list created using readlines() method, every line in file element in list. i'm iterating through occurances of "### server", grabbing lines after until next empty line(which signifies end of packet). must doing wrong, because not find() not working, have feeling there's better way grab between ### server , next occurance of blank line. any ideas? looking @ the file.readlines() doc: file.readlines([sizehint]) read until eof using readline() , return list containing lines read. if optional sizehint argument present, instead of reading eof, whole lines totalling approximately sizehint bytes (possibly after ro...

i have simple visual studio msi project. i want halt installation if detect running program of type (e.g. "aaa.exe") , wait until user closes before proceeding. how do that? generally speaking, have considered restart manager ? applications use windows installer 4.0 installation , servicing on windows vista automatically use restart manager reduce system restarts. default behavior on windows vista shut down applications rather shut down , restart operating system whenever possible. in cases system restart unavoidable, installers can use restart manager api schedule restarts in such way minimizes disruption of user's work flow. restart manager should automatically detect open files/handles-to-files are going updated .msi , gracefully stop/restart them.
