You have mail. (that you don't want from openssl)

Summary

Do you see the You have mail. when you open your terminal?

And do you see this in your mail? (in /private/var/mail/`whoami`)

WARNING: can't open config file: /usr/local/etc/openssl/openssl.cnf

If so, then perhaps your openssl is misconfigured.

Prevent the unwanted "You have mail." message by configuring your mac to use the brew installed version of openssl.

First, check which version of openssl you are running:


$ openssl version
OpenSSL 0.9.8za 5 Jun 2014

Next, backup stock version of openssl:


sudo mv /usr/bin/openssl /usr/bin/openssl_v0.9.8za

Now, install openssl using brew:


brew uninstall openssl
brew prune
brew cleanup
sudo brew install openssl

Then, make brew's openssl the system default:


sudo ln -s `find /usr/local/Cellar/openssl -name openssl| grep \/bin` /usr/bin/openssl

And verify that the openssl you are running is from brew:


$ openssl version -a
OpenSSL 1.0.1j 15 Oct 2014
built on: Fri Oct 17 21:14:05 BST 2014
platform: darwin64-x86_64-cc
options:  bn(64,64) rc4(ptr,char) des(idx,cisc,16,int) idea(int) blowfish(idx)
compiler: clang -fPIC -fno-common -DOPENSSL_PIC -DZLIB_SHARED -DZLIB -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -arch x86_64 -O3 -DL_ENDIAN -Wall -DOPENSSL_IA32_SSE2 -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_MONT5 -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DMD5_ASM -DAES_ASM -DVPAES_ASM -DBSAES_ASM -DWHIRLPOOL_ASM -DGHASH_ASM
OPENSSLDIR: "/usr/local/etc/openssl"


Create openssl.cnf File

Lastly, if you want to prevent the "WARNING: can't open config file: /usr/local/etc/openssl/openssl.cnf" message, you may need to create that file.

Here's one that should work:

#
# OpenSSL configuration file.
#
 
# Establish working directory.
 
dir     = .
 
[ ca ]
default_ca    = CA_default
 
[ CA_default ]
serial     = $dir/serial

new_certs_dir    = $dir/certs
certificate    = $dir/cacert.pem
private_key    = $dir/private/cakey.pem
default_days    = 3650
default_md    = md5
preserve    = no
email_in_dn    = no
nameopt     = default_ca
certopt     = default_ca
policy     = policy_match
 
[ policy_match ]

stateOrProvinceName   = match
organizationName   = match
organizationalUnitName   = optional
commonName    = supplied
emailAddress    = optional
 
[ req ]
default_bits    = 1024   # Size of keys
default_keyfile    = key.pem  # name of generated keys
default_md    = md5    # message digest algorithm
string_mask    = nombstr  # permitted characters
distinguished_name   = req_distinguished_name
req_extensions    = v3_req
 
[ req_distinguished_name ]
# Variable name    Prompt string
#-------------------------   ----------------------------------
0.organizationName   = Organization Name (company)
organizationalUnitName   = Organizational Unit Name (department, division)
emailAddress    = Email Address
emailAddress_max   = 40
localityName    = Locality Name (city, district)
stateOrProvinceName   = State or Province Name (full name)
countryName    = Country Name (2 letter code)
countryName_min    = 2
countryName_max    = 2
commonName    = Common Name (hostname, IP, or your name)
commonName_max    = 64
 
# Default values for the above, for consistency and less typing.
# Variable name    Value
#------------------------   ------------------------------
0.organizationName_default  = My Company
localityName_default   = My Town
stateOrProvinceName_default  = State or Providence
countryName_default   = US
 
[ v3_ca ]
basicConstraints   = CA:TRUE
subjectKeyIdentifier   = hash
authorityKeyIdentifier   = keyid:always,issuer:always
 
[ v3_req ]
basicConstraints   = CA:FALSE
subjectKeyIdentifier   = hash


Note that I made the certificate life 10 years. The rest is standard stuff.

How to Downgrade Node and NPM on OSX

Summary

Have the need to downgrade your Node and NPM installations?

If so, here's how I downgraded node from v0.10.33 to v0.10.25 and npm from 2.1.9 to 1.3.6.

Run these commands


sudo rm -rf /usr/local/lib/node_modules
echo prefix=~/.node >> ~/.npmrc
brew uninstall node
cd /usr/local/Library
git checkout bae051d /usr/local/Library/Formula/node.rb
curl -L https://www.npmjs.org/install.sh|pbcopy
# This is when I created the install-npm-1.3.6.sh file
chmod +x install-npm-1.3.6.sh
install-npm-1.3.6.sh
ln -s /usr/local/bin/node /usr/local/lib/node
ln -s $HOME/.node/lib/node_modules/npm/bin/npm-cli.js /usr/local/bin/npm


Created install-npm-1.3.6.sh File

I mainly replaced the "latest" text with "1.3.6".

#!/bin/sh

# A word about this shell script:
#
# It must work everywhere, including on systems that lack
# a /bin/bash, map 'sh' to ksh, ksh97, bash, ash, or zsh,
# and potentially have either a posix shell or bourne
# shell living at /bin/sh.
#
# See this helpful document on writing portable shell scripts:
# http://www.gnu.org/s/hello/manual/autoconf/Portable-Shell.html
#
# The only shell it won't ever work on is cmd.exe.

if [ "x$0" = "xsh" ]; then
  # run as curl | sh
  # on some systems, you can just do cat>npm-install.sh
  # which is a bit cuter.  But on others, &1 is already closed,
  # so catting to another script file won't do anything.
  curl -s https://www.npmjs.org/install.sh > npm-install-$$.sh
  sh npm-install-$$.sh
  ret=$?
  rm npm-install-$$.sh
  exit $ret
fi

# See what "npm_config_*" things there are in the env,
# and make them permanent.
# If this fails, it's not such a big deal.

Check Your Downgraded Versions


$ node -v
v0.10.25
\$ npm -v
1.3.6

Notes

To get the correct version of node to checkout you'll need to do something like this:

brew versions node | grep 0.10.25


... and to get brew versions to work you may need to run this:

brew tap homebrew/boneyard


I do not advocate downgrading node and npm.

This was for example purposes.

Reverting Back to Latest Versions

Not sure why any one would want to remove such a useful command, but for the time being you can use the brew versions command to get the git command used to download a specific node version (0.10.33 in our case).

$ brew versions node | grep 0.10.33
Warning: brew-versions is unsupported and will be removed soon.
You should use the homebrew-versions tap instead:
  https://github.com/Homebrew/homebrew-versions

0.10.33  git checkout 4b9395f /usr/local/Library/Formula/node.rb


$ brew clean
$ brew clean --cache
$ cd /usr/local/Library/
$ git checkout 4b9395f /usr/local/Library/Formula/node.rb
$ brew install node


Notes

No other combination of brew commands would upgrade node from 0.10.25 to 0.10.33.

So, none of these had any other effect, other than keeping node at version 0.10.25:

$ brew uninstall node
$ brew upgrade
$ brew clean 
$ brew clean --cache
$ brew upgrade node


Verify Versions

Verify that both node and npm are back to the latest versions:

~ $ node -v
v0.10.33
~ $ npm -v
2.1.9

For All Git Repos, Ignore All of This

Summary

Are there files that you are always having to add to the .gitignore file for all of your git repositories?

If so, use this technique to create a global ignore file that is automatically applied to all of your git repos on you local workstation.

For all git repos, ignore all of this

First, create the file to contain the global git ignore patterns:

~/.gitignore_global


# Compiled source #
###################
*.com
*.class
*.dll
*.exe
*.o
*.so

# Packages #
############
# it's better to unpack these files and commit the raw source
# git has its own built in compression methods
*.7z
*.dmg
*.gz
*.iso
*.jar
*.rar
*.tar
*.zip

# Logs and databases #
######################
*.log
*.sql
*.sqlite

# OS generated files #
######################
.DS_Store
.DS_Store?
._*
.Spotlight-V100
.Trashes
Icon?
ehthumbs.db
Thumbs.db
.idea
.metadata

/lex_ignore

Then, configure git to use the gitignore_global ignore patterns.

git config --global core.excludesfile ~/.gitignore_global

Script to Install or Update Go on OSX

Summary

Here's a bash script to Install or Update Go on OSX.

update-go


#!/bin/bash
function goversion {
    go version|cut -d" " -f3|while read n; do echo "${n:2}"; done    
}
set -x
brew update
brew doctor
{ set +x; } &>/dev/null
echo "Current Go version: `goversion`"
echo ""
echo "Need to do what brew doctor suggested? (It's safe to rerun this command.)  CTRL+C to stop --or-- Enter to continue..."
read x

if [ "`goversion`" == "" ]; then
    brew install go 
    brew link --overwrite go
else
    brew upgrade go
    brew link go
fi
echo "New Go version: `goversion`"

# Following currently enables intellij Go plugin to use new Go version
function reset-idea-go-plugin {
    if [ "`which idea`" != "" ]; then
        printf "intellij is installed.  Now, updating its go plugin..."
        # Note: version numbers may change
        rm /usr/local/Cellar/go/1.2.2
        rm /usr/local/Cellar/go/1.3
        ln -s /usr/local/Cellar/go/1.3.3 /usr/local/Cellar/go/1.2.2
        echo "Done."
    fi
} 

reset-idea-go-plugin 2>/dev/null

Output


~ $ update-go
+ brew update
Already up-to-date.
+ brew doctor
Your system is ready to brew.
Current Go version: 1.3.3

Need to do what brew doctor suggested? (It's safe to rerun this command.)  CTRL+C to stop --or-- Enter to continue...

Error: go-1.3.3 already installed
Warning: Already linked: /usr/local/Cellar/go/1.3.3
To relink: brew unlink go && brew link go
New Go version: 1.3.3
intellij is installed.  Now, updating its go plugin...Done.
~ $

Notes

It's safe to rerun this script.

Assumes you're on a mac.

Assumes you have homebrew installed.

If you use the Go plugin in IntelliJ, this script will direct it to use the newly installed version of Golang.
