This talk seems set out to prove that "XML is Bad". Yes XML-DSig isn't great with XPaths, but most of these attack vectors has been known for 10 years. There is probably a reason why the vulnerabilities found where in softwar

As having implemented EDIFACT parsers and translation layers, Universal Business Language (Oasis UBL) is a bliss to work with. Yes, it's a big standard and looks scary when starting out with it, but it is very well designed for a compl

I wish we would focus on making tooling better for W3C EXI (Binary XML encoding) instead of inventing new formats. Just being fast isn't enough, I don't see many using Aeron/SBT, it need a ecosystem - which XML does have.

Super interesting compiling pg, I assume, with same as the zfs block size! It was always on our todo to try, but never got around to it. If possible, what block size did you end up with? Have you tried zfs direct io in 2.3.x, if so, could y

If I may make an suggestion: Instead of a static json file, read at boot, I'd suggest passing the feature flags down per request as a header, or a pointer to the set of feature flag. So that all systems for a given request, observe the

I belive that Solaris (OpenSolaris) Zones predates LXC by around 3 years. Even when working with k8s and docker every day, I still find what OpenSolaris had in 2009 superior. Crossbow and zfs tied it all together so neatly. What OpenSolaris

Answer: Materalized Views. On a unrelated note: Still hoping for those automatically refreshed materalized views in PostgreSQL, ala what VoltDB has.

If one wanted to do server side rendering in Java with something like Turbo links, in 2020 - what would one use? JSP? Grails? JSF? Or just hit the bar instead? :-)

According to this IBM study [2]/Wiki article [0], the probability is much higher - per the study with 128GiB of memory it is every 1h 25min. There was an anecdote[1] about a Power Mac cluster at a university, which basically couldn&#x2

We run with ZFS over LUKS encrypted volumes in production on AWS ephemeral disks and have done so in over two years on Ubuntu 14.04 and 16.04. The major issue for us has been getting the startup order right, as timing issues does occur once

Please stop spreading this misinformed statement. I assume you are referring to the ZFS ARC (Adaptive Replacement Cache). It works in much the same way as a regular Linux page cache. It does not take much more memory (if you disable prefetc

We have been running ZFS on Linux in production since April 2015 on over 1500 instances in AWS EC2 with Ubuntu 14.04 and 16.04. Only one kernel panic observed so far, on a Jenkins/CI instance, but that was due to Jenkins doing magic on

Have you considered Rackspace's OnMetal products or other IaaS providers that run bare metal, such as Joyent Public Cloud? If you are in such a rush, I'll suggest to factor in both the migration risk and the time to deliver said h

I think we can build it however closed or open we would like it to be. The sharing of source code I suspect is more social than technical, therefore I don't expect much change. Java Applets, Flash, SilverLight always was at a disadvant

Maybe we should listen to Alan Kay's proposal: https://youtu.be/FvmTSpJU-Xc?t=1082 . It might be bad example, but if the Java SE runtime libraries was just a dependency like any other mvn artifact (module), Sun / O
