Standing on the other side of Lecture stand

It was a great experience of standing on the other side of the lecture stand. Normally i saw many people standing on the lecture stand and delivering lectures to the whole class. It seems very normal and is the routine of almost every professor to stand there and ask students to follow his instructions.

Also it was normal for me to just stand on the lecture stand and deliver the lecture. All the people stand after me in respect, some willingly and some unwillingly. But they stand still and waits for my instruction to sit down. All the faces were new to me so am i. So i started with little introduction about myself and my qualifications. All eyes ware looking at me as i am a magician who is going to open the box and a pigeon  flew out of it. But it was just my perception, i heard a sound from the last desk,"Sir we are unable to hear your voice, please speak loud". The first time i realize that it is not that easy as i thought. I just toned my throat and start from the beginning. I completed my introduction and asked them for giving the introduction.

They were the fresh undergraduate student who just started their UG. Their mind was not grown to the college level, as they were not expecting this thing. Nobody stand up for introduction. I ask a girl sitting at at the first bench for her introduction. She started with looking at her fellow classmates,"My name is...." and then stopped. I asked her about her past school and life she only uttered only 2-3 lines and then muted. This was the way of introduction of most of the students. Some were good, they explained their past life with confidence, may be the wordings was not correct but their level of confidence was much better than most of the students.

Install Apache2 from source in $HOME directory without root access

1. Download apache2 from source website.
2. Unzip
3. Make installation directory inside $HOME, i made "install" directory in my case.
4. Go inside the apache unzip directory
5. Run command ./configure --prefix=@HOME/path-to-install-directory.
6. make
7. make install
8. Then start apache by $HOME/path-to-install-directory/bin/apachectl start
          In my case it throws the following error:
          httpd: Could not reliably determine the server's fully qualified domain name, using               for ServerName
          (13)Permission denied: make_sock: could not bind to address [::]:80
          (13)Permission denied: make_sock: could not bind to address
          no listening sockets available, shutting down
          Unable to open logs
         So error given below is removed by changing the nameserver to localhost     
         httpd: Could not reliably determine the server's fully qualified domain name, using               for ServerName
         In my case i added ServerName localhost:80  in $HOME/path-to-install-                   directory/conf/httpd.conf 

          and again start apache by the command in step 8 the upper error disappeared but the remaining           was there. 

         so i get some ideas from this link 

         and made the following changes :  
                 I just add Listen 1025 in   $HOME/path-to-install-directory/conf/httpd.conf  file instead of 
                 Listen 80  and again start apache, this time it starts with no error.

Silly mistakes "Task 'saas' is not in your gulpfile" deploying sass with ionic framework

Here is the log of discussion on IRC

I am deploying ionic on ubuntu machine, i found an error with gulp
$ gulp saas
$ gulp saas
[12:06:36] Using gulpfile ~/myApp/gulpfile.js
[12:06:36] Task 'saas' is not in your gulpfile
[12:06:36] Please check the documentation for proper gulpfile formatting
yea this is with deploying to ios, like I said, Android is fine and still is working.
junmin has joined
it's either a problem with ionic, ios or cordova, but if anyone else serious is making interesting apps they know exactly what I'm talking about.
it's super aggravating.
← junmin has quit (Ping timeout: 240 seconds)
satinder. in your gulpfile, you need some lines that look somewhat like this:
gulp.task('saas', function() {
that's assuming you want to run a 'saas' task. (you maybe meant 'sass')
otherwise, just type 'gulp' as your command, and the 'default' task should run
joeco: yes it is there
gulp.task('default', ['sass']);
gulp.task('sass', function(done) {
that is not defining a new task. It is saying whatever is in the brackets is a dependency of 'default'
it is already present there
it means anything in the brackets has to resolve before 'default' is run.
so if you don't want sass, just erase it from the brackets
or else make a new .task() with 'sass' as the main name / definition
← dan2k3k4 has quit (Ping timeout: 246 seconds)
oh I see, you have one there
maybe it needs to be listed above the 'default'? just a guess
ok i am trying that way
are you sure the 'sass' task has something like this as the last line: .on('end', done);
ilmgb has joined
you have to call the 'done' so that it knows to start the next task
gulp.task('sass', function(done) {
errLogToConsole: true
keepSpecialComments: 0
.pipe(rename({ extname: '.min.css' }))
.on('end', done);
but still not working
qwebirc95493 has joined
well I don't know. but one other thing you can try, a really handy and simple/straightforward plugin is run-sequence on npm
i use it. you may restructure your order of gulp tasks, the sequence they run in.
maybe going threough that exercise will reveal why the 'sass' task is messed up.
okay, i will try that ,,,
It's OK, you're connected again :)

← blackjid has quit (Ping timeout: 240 seconds)
satinder, I think I know the real solution
can you check your ionic.project file?
under gulpstartuptasks: [] ... you have a misspelling.
← mickhansen has quit (Ping timeout: 240 seconds)
joeco: Which file
it should be in the root of your project
it is the startup file that is called when you do "ionic run android" or whichever
from there it calls gulpfile.js
yes it is there
"name": "myApp",
"app_id": "",
"gulpStartupTasks": [
"watchPatterns": [
this is the content of ionic.project file
mickhansen has joined
hmm.. that's strange. the "sass" matches the "sass" in your gulpfile
so I don't know why it said: Task 'saas' is not in your gulpfile
how about in your "watch" task, back in the gulpfile?
does it depend on "saas"?
no i don't think so
aasp@1313:~/myApp$ gulp watch
[12:33:25] Using gulpfile ~/myApp/gulpfile.js
[12:33:25] Starting 'watch'...
[12:33:25] Finished 'watch' after 11 ms
dan2k3k4 has joined
Actually i am not using the default sass files of the ionic project
wait, your original command you typed was "gulp saas"
that's why
what if you type "gulp sass"
yes it works!
ha. took the long way to get there :)

yes, thanks joeco

Adding two repositories to git.

Looking for adding two repo on same git, or say adding another repository other than origin in the same project.

1. Add first repo:

$ git add remote origin master <project repo url>
$ git push -u origin <branch>

2. Adding Second repo

$ git remote add <user> <project repo url>
$ git push <user> <branch>
