In order to reduce crime, the City of Berkeley decided to make business close for most of the night. They were successful, but this means that few places are still open when you’re up late studying.

So I’m listing restaurants that are open at the listed time and earlier:

12am midnight:

Fred’s Deli

Blondie’s Pizza

11pm:

House of Curries

10pm:

Tandor Kitchen

Note: This post is currently limited to the restaurants/stores that I frequent, but I’ll gladly add more restaurants if you comment with their names/hours. Also, if it closes before 10pm I’m not interested.

They need to make sure that they don’t have the same problem as the redacted PDFs of the FBI/CIA. You know, where you could copy-paste the words out from behind black boxes?

Yeah, we had that exact same problem. Except I’m not working for the FBI.

Google didn’t help one bit, “flatten pdf” means something entirely different to most people, so I couldn’t find it. Anyway, I chose to use the awesome tool ImageMagick.

I tried converting from PDF to PDF, but what happens is the filesize blows up if I want any sort of quality. Instead, I convert to PNG and then back to PDF.

So below is the shell script, with the only dependency being ImageMagick:

LINES=$(cat files.txt)
COUNT=0

for LINE in $LINES
do

COUNT=$(echo "$COUNT + 1"|bc)
echo -n "Working on $LINE.."

if [ -f fixed/$LINE ]; then
echo ". already done"
continue
fi

mkdir fixed/imgs-$LINE
convert -density 400 broken/$LINE fixed/imgs-$LINE/out.png
echo -n ".."
convert -density 400 fixed/imgs-$LINE/out*.png fixed/$LINE
rm -r fixed/imgs-$LINE
echo ". done"

done

It takes files in the file “files.txt” from the broken/ folder and outputs fixed ones to fixed/.

I did this to make sure the files were good and then let me upload them later. The broken/ folder is an sshfs mount to the original server mounted read-only.

Once they’re all fixed, I tested a bunch out and they were no longer copy-paste vulnerable and the info was completely boxed out with a similarly sized PDF

Looks like something the world should listen to. Well, at least the most polluting country in the world (the USA). If anyone knows the candidate of hope’s number, please let him know about wind energy’s superiority over everything he’s proposing.

If you don’t know his number, I recommend commenting this link to him here:

You can find a place to post the comment at the VERY bottom of the page.
