alexis2b | 4 years ago | on: Hypixel servers, biggest Minecraft community, down for days after DDoS attack

In what is reported as a DDoS attack, the servers of the largest online Minecraft gaming community (bedwars, skyblocks) have been unreachable for days. It looks like they had to setup again their whole infrastructure [0] as a result of “continuous ongoing large-scale attacks on the Minecraft server scene”.

As a funny side effect, hundreds of thousands of Minecraft players frustrated of not being able to access their favorite games are now taking it to YouTube with videos like “what to do when hypixel is down?” [1].

This article made me think immediately about a lot of discussions regarding blockchain suitability for a given use case.

I realized solving for a « no trust » environment is extremely expensive (even purely computationally if you look at proof of work as a solution).

Most of the times, deciding to start putting a little trust in the design saves a lot of complexity...

Interesting! Not trying to divert from Akka which is a wonderful piece of engineering, but your comment reminded me of Microsoft’s take at the Actor model with Project Orléans - which was used for the backend side of the Halo / XBox MMO [0].

I think the GA version of Project Orléans is now called Service Fabric, although I never had the pleasure to try it.

I am a big fan of BareTail and BareGrep when browsing and making sense of any very large set of log files. The pro versions are definitely worth your money: real-time match, regex-to-table log parsing, grep in tail / tail in grep, and all this in an incredibly minimalist UI and a single small exe.

CHF, B2 is considered the minimum proficiency level for business but acceptable.

Swiss salaries on the German-speaking side for senior engineers are in the 120k-160k bracket (Zürich area, depending on skills and domain). Speaking German natively will also score you above a lot of the local developers (expats from many non-German speaking countries). Taxes are much lower and quality of life is great, but also more expensive. PM me if interested and I can hook you up with local recruiters. Remote work might be possible.

For the non-French speaking audience, the name GCompris reads out “j’ai compris” which means “I understood”. Nice pun!

_ « if you can not afford to buy it, you certainly can not afford to build it »_

To eager business leads saying that a software or service is too expensive and we should build it internally instead...

It does not really matters, the purpose of salting is to avoid rainbow table attacks (i.e. comparing against precomputed dictionaries of known hashes). (Edit: typo)

Check fcsapi.com Not sure how the business is run but fiat and crypto are covered and it is free...

Maybe a counterpoint to the article conclusion (for the longer term). With the Covid crisis many companies discovered the benefits of remote working (or at least the lack of all the negative aspects they were fearing). My bet is that many more companies will adopt remote and distributed teams, which could be bullish in the long run for co-working facilities.

A famous example is the (in)famous trader Jérôme Kerviel who was deemed responsible for a 4.9 billions euro loss at Société Générale.

Having worked in Middle Office before being promoted to the Front, he had a really good knowledge of how operations and risk management worked in the bank (plus some still working write accesses to specific systems) which allowed him to mask his very large positions with fake opposite trades that he was putting in every day before the nightly risk snapshot and cancelling before they could be confirmed.

The guy basically did not take any holidays in two years - otherwise his large positions would have appeared on Risk radar pretty quickly...

If you are into those stories and want much more details than my poor summary I really recommend reading the SocGen post-mortem investigation.

Disclaimer: I worked at Société Générale during the Kerviel era - also there is a lot of controversy in France about how much the bank knew and let things happen (Kerviel was making a lot of profits - until he wasn’t) and if that was used to cover subprime related loss - this post does not represent an opinion on this case!

TL;DR; non-backward compatible schema migration (dropping an « unused » column) triggered errors on the previous authentication service version during rollout
