How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:

This can reduce files to ~15% of their size (2.3M to 345K, in one case) with no obvious degradation of quality.

ghostscript -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

Other options for PDFSETTINGS:

• /screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
• /ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
• /printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
• /prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.

Para onde caminha a comunidade brasileira de front end?

Hoje algo cômico e surreal aconteceu na comunidade FrontEnd Brasil. Algo chocante a ponto de desanimar o mais engajado dos participantes.

Após postar um Gist sobre moment com um código bastante didático, Berger foi rechaçado pelo moderador da comunidade, Jean Carlo Nascimento. Ao notar que o gist era escrito em CoffeeScript, o moderador comentou uma piadinha:

Prefiro usar moment a coffee.

A comunidade não gostou e reagiu, criticando o comentário infeliz e prezando o autor por compartilhar um código útil. Não satisfeito, as agressões sobre o uso de CoffeeScript continuaram.
