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 127.0.1.1               for ServerName
          (13)Permission denied: make_sock: could not bind to address [::]:80
          (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80
          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 127.0.1.1               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 http://askubuntu.com/questions/338218/why-am-i-getting-permission-denied-make-sock-could-not-bind-to-address-when 

         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

satinder

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

joeco

yea this is with deploying to ios, like I said, Android is fine and still is working.

→ junmin has joined

joeco

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.

joeco

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

satinder

joeco: yes it is there

gulp.task('default', ['sass']);

gulp.task('sass', function(done) {

gulp.src('./scss/ionic.app.scss')

joeco

that is not defining a new task. It is saying whatever is in the brackets is a dependency of 'default'

satinder

it is already present there

joeco

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

satinder

right

joeco

or else make a new .task() with 'sass' as the main name / definition

← dan2k3k4 has quit (Ping timeout: 246 seconds)

joeco

oh I see, you have one there

satinder

yes

joeco

maybe it needs to be listed above the 'default'? just a guess

satinder

ok i am trying that way

joeco

are you sure the 'sass' task has something like this as the last line: .on('end', done);

→ ilmgb has joined

joeco

you have to call the 'done' so that it knows to start the next task

satinder

gulp.task('sass', function(done) {

gulp.src('./scss/ionic.app.scss')

.pipe(sass({

errLogToConsole: true

}))

.pipe(gulp.dest('./www/css/'))

.pipe(minifyCss({

keepSpecialComments: 0

}))

.pipe(rename({ extname: '.min.css' }))

.pipe(gulp.dest('./www/css/'))

.on('end', done);

});

but still not working

→ qwebirc95493 has joined

joeco

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.

satinder

okay, i will try that ,,,

It's OK, you're connected again :)

joeco

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)

satinder

joeco: Which file

gulpfile.js

?

joeco

it should be in the root of your project

ionic.project

it is the startup file that is called when you do "ionic run android" or whichever

from there it calls gulpfile.js

satinder

yes it is there

{

"name": "myApp",

"app_id": "",

"gulpStartupTasks": [

"sass",

"watch"

],

"watchPatterns": [

"www/**/*",

"!www/lib/**/*"

]

this is the content of ionic.project file

→ mickhansen has joined

joeco

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"?

satinder

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

satinder

Actually i am not using the default sass files of the ionic project

joeco

oh

wait, your original command you typed was "gulp saas"

that's why

what if you type "gulp sass"

satinder

yes it works!

joeco

ha. took the long way to get there :)
