# Where should I go?

An old friend of mine just sent me an email:

Hey man!

Long time no see! How are you?

I had to relocate recently because of my job...

New country, new city, no friends... Need somebody like you to hang out with!

If you'll find some free time, come and visit me!

I remember you like puzzling, so I'll give you a challenge!

I am currently based in

$9945$

$10850$

$12942$

I hope I didn't make it too difficult. There's $3$ steps to decipher it:

1) change the system

2) visualise

3) translate

Flight tickets & drinks are on me if you'll figure it out until the weekend!

Regards

K

Help me find the name of the city hidden in those numbers!

HINT 1:

For the first step, you have to change the numerical system

HINT 2:

Binary

• Maybe try changing to hexadecimal or binary? – Daniel Scott Jun 14 '16 at 15:51
• @DanielScott You're right for the first step! You have to convert the numbers into another number system :) – Gintas K Jun 15 '16 at 7:41
• Huh. I tried base 26 yesterday and it didn't seem to do anything useful. I should have been less lazy and tried some more. – Gareth McCaughan Jun 15 '16 at 8:20
• aha! ⛙⩢㩞 oops that doesn't seem right. – Jasen Jun 15 '16 at 10:33
• Binary doesn't seem to make a nice bitmap (even after rearranging in various ways) – Gareth McCaughan Jun 15 '16 at 13:49

You should go to

Vilnius, Lithuania

"Change the System"

to binary.

this gives you

10011011011001
10101001100010
11001010001110

"Visualize" and "Translate"

using Braille. Stack the three binary numbers and separate into pairs of columns, forming 3x2 blocks.

10 = V

01
10 = I
00

10 = L

• You can use <br> to mark end-of-lines in spoiler blocks – Wu33o Jun 15 '16 at 14:20
• you have to add two spaces at the end of the line, so its like a line break :) – Gintas K Jun 15 '16 at 14:20
• more visuals and I will mark it :) – Gintas K Jun 15 '16 at 14:21
