CatLingo: Robotic Installation Workflow
The CAT Lingo robotic installation workflow allows to fully compile from source code, automatically setup a translation server, and link it up to the CAT Lingo cluster in one automated process.
We are able to keep the cost of everything down by automating everything possible.

ABN Tech Week trains engineers on the most important issues in building highly scalable software systems. The topic today is: How Discord Stores Trillions Of Messages?
HOW DISCORD STORES TRILLIONS OF MESSAGES
THE DIAGRAM BELOW SHOWS THE EVOLUTION OF MESSAGE STORAGE AT DISCORD:
MONGODB ➡️ CASSANDRA ➡️ SCYLLADB
IN 2015, THE FIRST VERSION OF DISCORD WAS BUILT ON TOP OF A SINGLE MONGODB REPLICA. AROUND NOV 2015, MONGODB STORED 100 MILLION MESSAGES AND THE RAM COULDN’T HOLD THE DATA AND INDEX ANY LONGER. THE LATENCY BECAME UNPREDICTABLE. MESSAGE STORAGE NEEDS TO BE MOVED TO ANOTHER DATABASE. CASSANDRA WAS CHOSEN.
IN 2017, DISCORD HAD 12 CASSANDRA NODES AND STORED BILLIONS OF MESSAGES.
AT THE BEGINNING OF 2022, IT HAD 177 NODES WITH TRILLIONS OF MESSAGES. AT THIS POINT, LATENCY WAS UNPREDICTABLE, AND MAINTENANCE OPERATIONS BECAME TOO EXPENSIVE TO RUN.
THEN COME SCYLLADB.

AT THE BEGINNING OF 2022, IT HAD 177 NODES WITH TRILLIONS OF MESSAGES. AT THIS POINT, LATENCY WAS UNPREDICTABLE, AND MAINTENANCE OPERATIONS BECAME TOO EXPENSIVE TO RUN.
THERE ARE SEVERAL REASONS FOR THE ISSUE:
– CASSANDRA USES THE LSM TREE FOR THE INTERNAL DATA STRUCTURE. THE READS ARE MORE EXPENSIVE THAN THE WRITES. THERE CAN BE MANY CONCURRENT READS ON A SERVER WITH HUNDREDS OF USERS, RESULTING IN HOTSPOTS.
– MAINTAINING CLUSTERS, SUCH AS COMPACTING SSTABLES, IMPACTS PERFORMANCE.
– GARBAGE COLLECTION PAUSES WOULD CAUSE SIGNIFICANT LATENCY SPIKES
SCYLLADB IS CASSANDRA COMPATIBLE DATABASE WRITTEN IN C++. DISCORD REDESIGNED ITS ARCHITECTURE TO HAVE A MONOLITHIC API, A DATA SERVICE WRITTEN IN RUST, AND SCYLLADB-BASED STORAGE.
THE P99 READ LATENCY IN SCYLLADB IS 15MS COMPARED TO 40-125MS IN CASSANDRA. THE P99 WRITE LATENCY IS 5MS COMPARED TO 5-70MS IN CASSANDRA.
HOW DOES THE BROWSER RENDER A WEB PAGE?
1. PARSE HTML AND GENERATE DOCUMENT OBJECT MODEL (DOM) TREE.
WHEN THE BROWSER RECEIVES THE HTML DATA FROM THE SERVER, IT IMMEDIATELY PARSES IT AND CONVERTS IT INTO A DOM TREE.
2. PARSE CSS AND GENERATE CSSOM TREE.
THE STYLES (CSS FILES) ARE LOADED AND PARSED TO THE CSSOM (CSS OBJECT MODEL).
3. COMBINE DOM TREE AND CSSOM TREE TO CONSTRUCT THE RENDER TREE.
WITH THE DOM AND CSSOM, A RENDERING TREE WILL BE CREATED. THE RENDER TREE MAPS ALL DOM STRUCTURES EXCEPT INVISIBLE ELEMENTS (SUCH AS <HEAD> OR TAGS WITH DISPLAY:NONE; ). IN OTHER WORDS, THE RENDER TREE IS A VISUAL REPRESENTATION OF THE DOM.
4. LAYOUT.
THE CONTENT IN EACH ELEMENT OF THE RENDERING TREE WILL BE CALCULATED TO GET THE GEOMETRIC INFORMATION (POSITION, SIZE), WHICH IS CALLED LAYOUT.
5. PAINTING.
AFTER THE LAYOUT IS COMPLETE, THE RENDERING TREE IS TRANSFORMED INTO THE ACTUAL CONTENT ON THE SCREEN. THIS STEP IS CALLED PAINTING. THE BROWSER GETS THE ABSOLUTE PIXELS OF THE CONTENT.
6. DISPLAY.
FINALLY, THE BROWSER SENDS THE ABSOLUTE PIXELS TO THE GPU AND DISPLAYS THEM ON THE PAGE.
ABN Tech Week trains engineers on the most important issues in building highly scalable software systems. The topic for today is: HOW DO VISA AND MASTERCARD PREVENT CNP (CARD-NOT-PRESENT) FRAUD?
THE DIAGRAM BELOW SHOWS HOW 3-D SECURE PROTOCOL WORKS IN ORDER TO PROTECT ONLINE PURCHASES FROM CNP FRAUD.
3-D SECURE (3DS) PROTOCOL IS AN ADDITIONAL 𝐬𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐥𝐚𝐲𝐞𝐫 FOR ONLINE CARDS TRANSACTIONS. IT WAS ORIGINALLY DEVELOPED IN 1999, AND THE LATEST VERSION (VERSION 2) WAS PUBLISHED IN 2016 TO COMPLY WITH NEW EU AUTHENTICATION REQUIREMENTS.
3-D REFERS TO THE “THREE DOMAINS” – THE ACQUIRER DOMAIN, THE ISSUER DOMAIN, AND THE INTEROPERABILITY DOMAIN.
𝐅𝐫𝐢𝐜𝐭𝐢𝐨𝐧𝐥𝐞𝐬𝐬 𝐅𝐥𝐨𝐰 – NORMAL TRANSACTIONS
🔹 STEPS 1-2: A CONSUMER MAKES AN ONLINE PURCHASE AND HITS CHECKOUT TO ENTER PAYMENT CARD DETAILS. IF THE MERCHANT’S WEBSITE ENABLES 3DS, THE 3D SERVER SENDS THE AUTHENTICATION REQUEST TO THE DIRECTORY SERVER (DS).
🔹 STEPS 3-6: BASED ON THE PRIMARY ACCOUNT NUMBER (PAN), DS FINDS THE CARD ISSUER’S ACCESS CONTROL SERVER (ACS) AND CHECKS IF THE CARD IS REGISTERED IN 3DS. THE RESPONSE IS SENT BACK TO DS, MERCHANT, AND CARDHOLDER.
🔹 STEPS 7-10: NOW THAT THE CARD IS AUTHENTICATED, THE CARDHOLDER CAN PROCEED WITH THE PAYMENT REQUEST. THE REQUEST GOES THROUGH THE ACQUIRER AND THE CARD NETWORK AS USUAL.
𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞 𝐅𝐥𝐨𝐰 – SUSPICIOUS TRANSACTIONS
🔹 STEPS 1-6: THE STEPS ARE THE SAME WITH THE FRICTIONLESS FLOW. HOWEVER, THE CARDHOLDER IS PROMPTED TO ENTER PROOFS TO VERIFY THE CARD OWNERSHIP.
🔹 STEPS 7-9: THE CARDHOLDER CAN VERIFY VIA OTP (ONE-TIME PASSWORD), SAFETY QUESTIONS AND BIOMETICS. THE RESULTS ARE SENT BACK VIA DS, SO IS MORE SECURE.
🔹 STEPS 10-13: IF THE CARD IS AUTHENTICATED, THE CARDHOLDER CAN CONTINUE WITH THE ONLINE PAYMENT TRANSACTION.

ABN Tech Week trains engineers on the most important issues in building highly scalable software systems. The topic today is: What distinguishes MVC, MVP, MVVM, MVVM-C, and VIPER architecture patterns from each other?
WHAT DISTINGUISHES MVC, MVP, MVVM, MVVM-C, AND VIPER ARCHITECTURE PATTERNS FROM EACH OTHER?
THESE ARCHITECTURE PATTERNS ARE AMONG THE MOST COMMONLY USED IN APP DEVELOPMENT, WHETHER ON IOS OR ANDROID PLATFORMS. DEVELOPERS HAVE INTRODUCED THEM TO OVERCOME THE LIMITATIONS OF EARLIER PATTERNS. SO, HOW DO THEY DIFFER?
🔹 MVC, THE OLDEST PATTERN, DATES BACK ALMOST 50 YEARS
🔹 EVERY PATTERN HAS A "VIEW" (V) RESPONSIBLE FOR DISPLAYING CONTENT AND RECEIVING USER INPUT
🔹 MOST PATTERNS INCLUDE A "MODEL" (M) TO MANAGE BUSINESS DATA
🔹 "CONTROLLER," "PRESENTER," AND "VIEW-MODEL" ARE TRANSLATORS THAT MEDIATE BETWEEN THE VIEW AND THE MODEL ("ENTITY" IN THE VIPER PATTERN)
🔹 THESE TRANSLATORS CAN BE QUITE COMPLEX TO WRITE, SO VARIOUS PATTERNS HAVE BEEN PROPOSED TO MAKE THEM MORE MAINTAINABLE
