gcoleman··on IBM RISC System/6000 Family
A blast from the past! Years ago I worked on some J2EE nonsense to do e-commerce websites on top of a Pick application. It was I think called Mailbrain, I think running on HPUX though I could be mis-remembering. There was a horrible text based socket protocol for passing data records back and forth.

I do remember the Pick greybeards being dismissive of this new fangled SQL stuff: "we had relational databases before SQL don't you know"

gcoleman··on London Street Trees
It's based on data from councils and tfl, so council run parks are included (e.g. Gunnersbury near where I live) but not royal parks (like Richmond park)
gcoleman··on Apple apps on Big Sur bypass some firewalls and VPNs
Many geo-ip services also offer VPN or server detection (e.g. is the IP in one of the EC2 ranges).

In a previous job at an online gambling company we found that a large percentage of fraudulent user accounts came from VPNs so ended up banning them at the geo lookup stage.

gcoleman··on Ask HN: Who Is Firing?
It depends on the type of gambling. Sports based gambling has basically disappeared. Bingo/slots/casual games are up in general I think.
gcoleman··on FreeBSD has removed GCC from its base system
OP here. I assumed knowledge of how FreeBSD works and the ongoing efforts to move to clang. I can see how the title could be misleading for people who are not familiar.

As others have pointed out "FreeBSD has removed GCC from the. base system" would be a better title.

gcoleman··on Sunsetting Mercurial Support in Bitbucket
Visual Sorta-Safe, we used to call it.
gcoleman··on London bans cars for a day in the fight against air pollution
That's not true - season tickets are definitely cheaper than pay as you go if you travel every day.

e.g. Annual Travelcards give you 12 months travel for the price of ten and a half.

gcoleman··on Winter Is Coming for Java Updates
I thought Redhat were backporting fixes to OpenJDK 8 and 11:

gcoleman··on Neo4j nabs $80M Series E as graph database tech flourishes
We're using neo4j for fraud detection in online gambling and it's very useful for spotting rings of duplicate/related account etc.

One benefit I didn't think of before but has become clear: non-technical people find viewing and manipulating the graphs very easy, and explaining the links is much simpler.

gcoleman··on Ask HN: Who is hiring? (March 2018)
Gaming Realms | Multiple tech positions | London | Onsite

Gaming Realms creates, develops and markets interactive online gaming applications, including slingo, slots and casino real-money products. We're looking for 4 roles across infrastructure, development and QA.

We are looking for:

- Infrastructure Manager: Lead a team of 4 who oversee all our infrastructure: AWS, Google Cloud, colo, private cloud deployments across US, Europe and Asia. There is also a growing desktop support element to support PCI compliance.

It's a hands on role so you'll need to be comfortable in the terminal, scripting etc. We are heavy users of puppet so you'll need a DevOps mindset, and know how AWS and Linux work. The job involves guiding the direction of the tech, managing a team, managing costs. You'll have the freedom to innovate the tech and team structure as long as the job gets done.

Full job spec http://bit.ly/2EZis9f

- Junior Java Developer: join a team of 6 developers working on our backend platform. You'll be joining a sub team specialising in remote gaming integrations so interest in integration projects would be great (idempotent requests, how to deal with timeouts..). It's a junior role so we're not too fussed about specific technologies but it does involve working with third parties a lot so good troubleshooting and communication skills are key.

- QA Engineer: http://bit.ly/1iLGLYU

gcoleman··on Why Some Cars Have Gas Tank Fillers on the Left or the Right
I do it all the time and it's never scratched the paint of my (admittedly small) car. It makes it much more efficient to just drive up to any spare pump without worrying about the side.
gcoleman··on Why Some Cars Have Gas Tank Fillers on the Left or the Right
I have driven in the UK for 12 years and genuinely have never heard of that rule (obviously did not study the highway code well enough before the test).

Do people actually pay any attention to it?

gcoleman··on Is it OK to hold credit card numbers in cookies, Santander?
I've also found the customer service to be pretty good for the standard stuff but there is a blurry line between smile and The Co-operative Bank that confuses them.

For example, I can pay in a cheque or withdraw funds over the counter in a Coop Bank branch, but if I want to set up a foreign bank transfer I have to use the an online secure message. When I asked why I was told over and over "smile is an online bank". Which I suppose is true, up to a point.

gcoleman··on The Unwelcome Mat - How Not to Attract Tourists
Flying into LAX last year I had to do ESTA before I left, fill out 2 forms on the plane, and also give some of the same information to the airline when I checked in in London.

I don't really mind having to fill out some forms to get into a country, it's having to do the same thing 4 times that's annoying.
