- Check if there are duplicated emma jars in the system 
- Could be caused by there's no yet any run against the server, hence there's no coverage.ec generated on the server port 
- Check if the gen/metadata.emma is the latest, i.e. if it is the result of instrumentation of the current code on the Server 

bypass proxy

export the proxy env first:

export http_proxy=http://webproxy:3128

redhat

e.g.
wget http://ant.apache.org/bindownload.cgi/apache-ant-1.8.2-bin.tar.gz

NOTE: wget usually give header problem to .tar.gz files

ubuntu:


gem (—http-proxy root:balmor@webproxy:3128) install rails --debug

ssh without password

How to do it (NOTE: sometimes it uses 'dsa' instead of 'rsa')

First log in on A as user a and generate a pair of authentication keys. Do not enter a passphrase:

a@A:~> ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa): 
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A

Now use ssh to create a directory ~/.ssh as user b on B. (The directory may already exist, which is fine):

a@A:~> ssh b@B mkdir -p .ssh
b@B's password: 

Finally append a's new public key to b@B:.ssh/authorized_keys and enter b's password one last time:

a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
b@B's password: 

From now on you can log into B as b from A as a without password:

a@A:~> ssh b@B hostname
B

Spreadsheet sum with condition of value of a column

3 down vote favorite

I want a spreadsheet function that will produce a sum of all values in column B for when column A is equal to 'X' and when it is equal to 'Y' A B X 10 Y 3 X 7 X 22 Y 4 Y 9 The output should look like the following (where 39 & 16 are the results of the formulas): X 39 -> 10 + 7 + 22 Y 16 -> 3 + 4 + 9 Symphony , Excel as well? X 10 Y 3 X 7 X 22 Y 4 Y 9 X "=SUMIF(A1:A6;A8;B1:B6)" Y "=SUMIF(A1:A6;A9;B1:B6)"

Array to list and vice versa

Convert an array to a list.

List<Date> listOfDates = Arrays.asList(arrayOfDates);

On the fly list construction:

List<Date> listOfDates = Arrays.asList(new Date[]{date1, date2});

Convert a list into an array:

Date[] arrayOfDates = listOfDates.toArray(new Date[]{});
-------------------------

Date[] arrayOfDates = listOfDates.toArray(new Date[0]);
