Waltham company in a really black mood

Dezeen reports that NanoLab, which develops products based on carbon nanotubes, has developed a paint that could be one of the blackest paints ever produced.

All interesting as it goes, but NanoLab says it will sell its pigment to anybody, unlike rival NanoSystems, which granted exclusive rights to its blackest-black paint to a British artist - which sparked one of his rivals to come out with a pink paint that he would sell to anybody who signed a contract agreeing they were not that guy and would not give him any of that paint.

Racists get their rally permit; Boston bans all food and clothing vendors from Common on Saturday

WBUR reports city officials have granted a permit to white supremacists for a rally on Boston Common on Saturday.

Boston police are urging people not to bring backpacks, sticks or anything that can be used as weapons. Police are planning to have extra officers on hand, as well as barriers to separate demonstrators and counter-demonstrators.

The Dig has details on the two counter-protests being planned.

On Monday, Mayor Walsh vowed to keep the city safe and said he was urging any families thinking of coming into Boston on a nice summer day to continue with their plans. One thing those families won't be able to do, however, is buy an hot dog or soda or try on a T-shirt or ball cap, because the city Parks and Recreation Department has banned all of the vendors who normally ply their wares along the Common's main paths.

In an e-mail to vendors yesterday, a Parks Department manager told the vendors:

Per order of the Boston Police Department and the Boston Parks Commissioner there will be NO VENDING OPERATIONS ALLOWED ON BOSTON COMMON on Saturday, August 19th. No vehicles will be allowed on the Boston Common as of 7:00 a.m. and throughout the day as needed.

I do apologize for any inconvenience this causes, however, public safety is of the utmost importance to the City of Boston. Please reach out to me if you have any questions. As more information becomes available I will update you accordingly.
