Woking behind the proxy 각종 프로그램에서 프록시 설정하기

오늘 

I have troubled while using programs which use networks behinde proxy. So I summerized  how to configure proxy.

I found some similar document like mine. but a little different. 

nodejs & npm & ionic 

• set NODE_TLS_REJECT=0
• SET PROXY=HTTP://000.00.00.00:00
• npm config set proxy http....
• npm config set https-proxy http://xxxx

git

        git config --global http.proxy http://xxxxx

        or .gitconfig 

              [http]  

                 proxy = http://xxx.xxx.xxx:0000

curl

• export http_proxy=http://aaa.aa.aa.aa.:0000
• export https_proxy=http:/aaa.aa.aaa.aa:0000
• curl -x http://xx.xxx. 
• curl --proxy http://sss.sss

java

• -Dhttp.proxyHost=xxx.xxx.xxx -Dhttp.proxyPort=0000



-Dhttps.proxyHost=xxx.xxx.xxx -Dhttps.proxyPort=0000
• or using system proxy 
• java -Djava.net.useSystemProxies=true

apt-get

•  cd /etc/apt
• sudo vi apt.conf
• Acquire::http::proxy "http://xxx.xxx.xx:000"

python pip

  pip install --proxy http://xxx.xxx:000 modulename 

  cert error : 

       pip --cert certfile.pem install moduleName

      ** using config 

          pip/pip.conf

         [global]

         cert=/aaa/aaaa/certfile.pe

** when ssl error is occurred.

(pip version: 8.0.2)

pypi.python.org is download server.

pip install module_name --trusted-host pypi.python.org

gradle

gradle.properties

 systemProp.http.proxyHost=111.111.111.111

 systemProp.http.proxyPort=111

 systemProp.https.proxyHost=222.222.222.222

 systemProp.https.proxyPort=111

스위프트에서 세자리마다 쉼표찍기( Show comma on every 3 digit in swift -Number formatting)

//: Playground - noun: a place where people can play

import UIKit

func convertCurrency( money : NSNumber, style : NSNumberFormatterStyle ) -> String {

    

    let numberFormatter = NSNumberFormatter()

    numberFormatter.numberStyle = style

    

    return numberFormatter.stringFromNumber( money )!

}

let value = 12345678.123

convertCurrency(value, style : NSNumberFormatterStyle.DecimalStyle)

convertCurrency(value, style : NSNumberFormatterStyle.NoStyle)

convertCurrency(value, style : NSNumberFormatterStyle.CurrencyStyle)

#=========== Output  ===================

12,345,678.123     <-- decimalstyle="" font="">

12345678             <-- font="" nostyle="">

$12,345,678.12     <-- currencystyle="" font="">

Rounded square button in swift ( customizing shape and color in code)

override func viewDidLoad() {

        super.viewDidLoad()

     let TAG_BTN = 1001  // it is assigned to button which you want to change properties.

     let btn : UIButton  = self.view.viewWithTag(TAG_BTN) as! UIButton

     btn.layer.cornerRadius = 5

     btn.layer.borderColor = UIColor.grayColor().CGColor

     btn.layer.borderWidth = 1.5

     btn.backgroundColor = UIColor(red: 1.0, green: 0, blue: 0, alpha: 1)

}

Removing space of table seperator ( Drawing sperator full width)

http://www.malcontentboffin.com/2014/10/28/Make-iOS-8-Table-View-Cell-Separators-Full-Width

    override 

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {

        //remove identation line ( draw full seperator.)

        cell.separatorInset = UIEdgeInsetsZero

        cell.layoutMargins = UIEdgeInsetsZero

        cell.preservesSuperviewLayoutMargins = false

    }

using image as x repeated background in swift

I found many solutions above title. but It is written in a objective-c  like that:

objView.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"background_image"]];


but in swift   it can be written like that:

 objView.backgroundColor = UIColor(patternImage: UIImage(named: "background_image")!)

Using UITableView in ViewController (iOS Swift)

When I make UIViewController,  I need to display list , so I think I can use UITableView in UIViewController , but I found it is not possible because of mechanism of iOS.

They provide  another way.  That is using UIContainerView.

In Storyboard,
1) Drag UIViewController
2) Drag  UIContainerView into UIViewController( step.1)
    segue and default view controller will be created.
3) Drag UITableViewController  ( not UITableView)
4) delete segue and default view controller (step.2)
5) Link container  to UITableViewController (step.3)
     - (how to link?: click container with control key and drag to UITableViewController)

** Additional step
    If you have a existing segue with other viewcontroller, you may meet error. So you must check segue.identifier.

simple compile erlang

I read that  I must use 'c' to compile in erlang. but I met error 'write error'.
I  am googling and then  I know that I must change directory with 'cd' command.
It is simple. but before I found it  It was stress to statr to learn the erlang.



c("modulefilename").   % sometimes you will meet error ' writing error'


%% method 1: you need to change working directory.

cd("pathname"). %%  which includes module file
c("modulefilename").

%% method 2  

c("modulename", [{outdir, "output directory .."}]).  %% you can assign output directory option  by {outdir, "..."} .
