can please explain me implementation of printf prints string correctly? version 1: printf(const char * s) { while(*s != '\0') { write(s, 1, f); s++; } } version 2: printf(const char *s) { write(s, strlen(s), f); } both print "a string correctly". print given string in argument correctly. if question better implementation suggest depends on implementation of write. option 1 slower if write call has large enough overhead or can buffer characters before committing write. option 2 slower if write unoptimized. example puts character character on serial connection. here pay additional iteration of string strlen. note write call takes file descriptor first argument, not last.

when try compile ffmpeg libx265 (./configure --enable-gpl --enable-libx265), getting error as: (error: x265 not found using pkg-config). how install libx265 , configure ffmpeg. there 2 solutions problem. a) if there no libx265 available on centos 7 you'll have build yourself. follows pretty straightforward method of configure/make. using mercurial: hg clone http://hg.videolan.org/x265 cd x265/build/linux ./make-makefiles.bash make -j6 make install ldconfig then sure specify path libx265 installed when building ffmpeg. pkg-config: pkg_config_path="/usr/local/lib/pkgconfig" . b) but appears there rpm entries x265 on centos 7: http://pkgs.org/centos-7/nux-dextop-x86_64/x265-devel-1.2-6.el7.nux.x86_64.rpm.html . if compatible on system should able install instead of building.

is there way write dataoutputstream content array or string regardless type of data contains? dataoutputstream output = new dataoutputstream(new bufferedoutputstream(new fileoutputstream(string datapath))); thanks use bytearrrayoutputstream. https://docs.oracle.com/javase/7/docs/api/java/io/bytearrayoutputstream.html bytearrayoutputstream baos = new bytearrayoutputstream(); outputstream os = new dataoutputstream(baos); os.write(...); byte[] data = baos.tobytearray(); string dataasstring = new string(data, "utf-8"); // or whatever encoding using you may use following strategy well: class compositeoutputstream implements outputstream { private outputstream first,second; public compositeoutputstream(outputstream first, outputstream second) { this.first = first; this.second=second; } public void write(int b) throws ioexception { first.write(b); second.write(b); } // etc. } use with: bytearray

i'm using symfony2 generate forms, or twig, uses symfony's functions, view looks this: {{ form_start(form) }} {{ form_widget(form) }} {{ form_end(form) }} this generates html code without newlines or indentation. unreadable when html source code. is there way force symfony/twig format generated html? this link explains form customization in twig beautifully. there numerous ways of applying css styling form elements. example, if have form field name can add css class way: {# render widget, add "foo" class #} {{ form_widget(form.name, {'attr': {'class': 'foo'}}) }} or label: {{ form_label(form.name, 'your name', {'label_attr': {'class': 'foo'}}) }} then can use css classes render form elements per design. hope idea. docs , link provided in answer both useful in regard.

i trying figure out if node package pm2 installed in path , executable or not following puppet code. exec { "create symbolic link pm2": cwd => "${pm2_link_dir}", path => ['/usr/bin','/bin','/usr/sbin','/sbin'], onlyif => "! node &> /dev/null", command => "ln -s ../lib/node_modules/pm2/bin/pm2 pm2" } it telling me cannot find command "!". right way find out if program installed , executable?? , why puppet cannot understand not operator?? working on redhat master , slave. and why puppet cannot understand not operator? the ! operator provided shell; not command. using exec 's default provider ( posix ) runs commands directly rather via shell. (or documented do. has come light posix provider runs commands via shell, in apparent contradiction of docs.) it anyway bit silly use ! in exec 's onlyif attribute, when instead drop ! , switch
