The last day at the Belgrade office. See also day one, day two, day three and day four.

Went to the Farmer’s market “Zeleni venac” (Пијаца „Зелени венац“) before breakfast (make sure you look at the smileys in the pickled vegetables jars), to see something of the city at daylight! Around noon it started snowing, and we’re now at the airport.

Record Stores in Belgrade, Serbia

Here’s my small guide to shopping for vinyl records in Belgrade. You won’t find any bargains when shopping for new vinyl here: the prices are the same or higher compared to the Netherlands, or any other Western European country. I did find some great new and second-hand local records though!

Usce Shopping Mall

At this mall I found the smallest record store ever! It’s a small stall on the ground floor powered by Metropolis Music and Mascom Records.

The Vulkan bookstore at the top level has a small vinyl section:

At this store I bought the above record for 2499 RSD: Golden Horns - The Best Of Boban I Marko Marković Orkestar. I first heard this music in Emir Kusturica’s epic 1995 movie Underground:

Here are two of the songs on the album:

Muzička kuća Metropolis

A large record store that also doubles as a bar. Didn’t buy anything there. Open until late at night.


Didn’t go in there because it looked like they only sold CD’s.

Felix Shop

This place mostly sells rock-band t-shirts and has a very small selection of CD’s and also - surprisingly - some cassettes. It’s at the first floor of the building.

Knjižare Vulkan

This Vulkan book store has a small selection of vinyl records in the basement.

Yugovinyl record store Belgrade

This is my favourite record store in Belgrade, with a huge selection of vinyl records, both new and second-hand. It was a bit hard to find: when you think you’re looking at the entrance of a parking lot you’re in the right place. Very friendly and helpful staff, and there’s a record player with headphones were you can listen to the stuff you pick from the crates and shelves. Prices are on the inside of the records. Open all evening! I bought one new and five second-hand (priced between 800 - 2000 RSD) Serbian/Yugoslavian records there, mostly brass bands. They also had an impressive collection of Turkish 70’s psychedelic rock, for example.

Here’s what I bought at Yugovinyl:

Listen to the funky drumming on this track by Zorica Markovic:

Frantic brass and a resolutely non-4/4 time signature on this track by Redzepova Usnija:

And finally the Duvački Orkestar Radovana Babića ‎in action:

Static And Dynamic Caching On Incapsula Can Cause CORS errors

We’re loading an SVG sprite via AJAX from our CDN because SVG is XML and that’s not allowed to be loaded cross-domain. That all worked fine across all our environments, but it broke on production:

Access to XMLHttpRequest at '' from origin 
'' has been blocked by CORS policy:
No 'Access-Control-Allow-Origin' header is present on the requested resource.

That was strange because for the “” app service was already configured to allow all origins: “ALLOWED ORIGINS = *”.

It turned out the Incapsula WAF caching was configured to Static + Dynamic. After disabling caching in Incapsula the CORS error was gone.

Business Trip To Belgrade, Serbia - Day 3

The third day at the Belgrade office. See also day one and day two.

Some office photos: yes, there are standing-, pool- and table football tables, just as we have in Amsterdam. Dinner at the lovely Majstor i Margarita restaurant (*), adventurous cocktails at the well-hidden Beogradski Koktel Klub, and some street photos, including the second of two pieces of street art advertising veganism I saw tonight.

(*) The Majstor i Margarita restaurant is probably named after “one of the best novels of the 20th century”

From Wikipedia:

The Master and Margarita (Russian: Мастер и Маргарита) is a novel by Russian writer Mikhail Bulgakov, written in the Soviet Union between 1928 and 1940 during Stalin’s regime. A censored version was published in Moscow magazine in 1966–1967, after the writer’s death. The manuscript was not published as a book until 1967, and then first in Paris. A samizdat version circulated that included parts cut out by official censors, and these were incorporated in a 1969 version published in Frankfurt. The novel has since been published in several languages and editions.

The story concerns a visit by the devil to the officially atheistic Soviet Union. The Master and Margarita combines supernatural element with satirical dark comedy and Christian philosophy, defying a singular genre. Many critics consider it to be one of the best novels of the 20th century, as well as the foremost of Soviet satires.

Business Trip To Belgrade, Serbia - Day 1

This week the Amsterdam part of our team (two developers, two testers plus our Manager New Business Development and Senior Director Software Engineering) are in Serbia to join the Belgrade part of our team (two developers working there via a nearshoring construction).

Normally we communicate via chat and video-conferencing with Teams, but it’s also very important to work face-to-face once in a while. Last time they came to Amsterdam, so now we’ve come to Serbia.

These are the photos of day one. Some frst impressions: very photoghenic Brutalist architecture and picturesque cobblestone streets, OMG they’re smoking in restaurants!, nice beer, nice food, nice Slivovitz.

Belgrade reminds me of places like Vienna and Prague, but also of Istanbul: you’re in eastern Europe but also closer to the heart of the former Ottoman Empire.

Everybody Loves Ringo Photobook

We have two dogs (and three cats, two hairless rats, a sweet water aquarium, a pond in the garden with koi, goldfish and a sturgeon, and five beehives), and both of them have instagram accounts: the chichuahua Ringo has @everybodylovesjuno and the whippet greyhound Juno has @everybodylovesringodog.

As a Sinterklaas present for my wife I created this 24-page 14 x 14 cm hard cover photo book on Albelli:

RELX End Of Year Party

This year’s RELX End Of Year Party (that’s a party for all of RBI, Elsevier and LexisNexis in the Amsterdam location) was held at the KIT Royal Tropical Institute and this was the dresscode:

Come dressed as a magical forest creature: a fairy, an elf, a unicorn, or maybe a dragon?
Come as your favourite character from Middle Earth, Avatar or Sherwood fairy-tale forest.
Wrap yourself in lights, leaves and leprechaun hats and create your own mystical forest character.

It was fun!
