Firefox upcoming feature: Tab Candy — Just in case you’ve missed it

This fea­ture already gain­ing a lot of atten­tion, and I believe that once it shows up, and peo­ple really start extend­ing it, it will be one of the Killer Fea­tures that Fire­fox will have to offer. Some­thing that is really needed for Fire­fox to start bit­ing back some mar­ket share from Chrome.

Single command to generate & copy public SSH key

I always for­get how to run this sim­ple com­mand, so I’ll just leave it here so you can use it and I won’t for­get it.

Reg­u­lar Gen­er­ate & Copy pub­lic SSH keys

$ ssh-keygen; ssh-copy-id user@host; ssh user@host

Just change the user@host and you’re on your way.

Cus­tom Port

If your host has a dif­fer­ent SSH access port, then it get’s a lit­tle trick­ier, but still works:

$ ssh-keygen; ssh-copy-id ‘-p XXXX -i ~/.ssh/id_rsa.pub username@host’; ssh user@host

Note that the ssh-copy-id call is a lit­tle dif­fer­ent, and exe­cute in quotes (if you copy & paste, the single-quotes can cause error, so replace them with nor­mal single-quotes).

Competition doesn’t always produce better performance

An inter­est­ing test results show that humans per­form bet­ter when com­pet­ing against teams/individuals of a lower class. i.e. A good devel­oper would work faster when com­pet­ing against a new­bie or a worse-performing developer.

This could mean a lot, and per­haps explain why some places can­not man­age sim­pler tasks they did man­age before bring­ing in some heavy duty expert.

Quote from the article:

Another light in which it might be infor­ma­tive to view this study is with respect to research into what’s called “stereo­type threat.” This is a well-known effect in which stig­ma­tized groups — such as African-Americans or women — per­form worse when prompted to focus on neg­a­tive stereo­types about their group. Thus, African-Americans tak­ing the SAT, if asked to check a box list­ing their race before the test, will per­form worse than if they were not pro­moted to do so. Con­versely, Asian stu­dents asked to mark their race tend to per­form bet­ter, because of pos­i­tive stereo­types about aca­d­e­mic achievement.

Or, take the case of a female, Asian stu­dent — prompted to think about her Asian iden­tity, she is likely to per­form bet­ter; prompted to think about her female iden­tity, she is likely to do worse.
