Five Things: Boston Marathon, 'Inside Obama's Presidency'

1) Run the Boston Marathon
Getting a bib for the Boston Marathon can be difficult, and the American Liver Foundation wants to let runners know it still has spots on its Run for Research team. More here.

2) Inside Obama's Presidency
This Frontline film, co-produced by a Somerville resident, takes a look at President Obama's first term in office. It airs tonight at 10 p.m. on WGBH (see air times here). You can also watch online.

3) Coming soon: Girl Scout cookies
If you love Girl Scout cookies, put Feb. 3 on your calendar. Somerville's Troop 77178 will be outside the Porter Square Shaw's selling cookies on that day.

4) Karaoke at Rosebud
Head to Rosebud Bar & Grill at 8 p.m. for Tuesday night karaoke.

5) Weather
Today will be partly sunny with a high around 42.
