Raw Unapologetic Firepower: kdb+ from @Kx

While the day job builds (hyperconverged) appliances for big data analytics and storage, our partners build the tools that enable users to work easily with astounding quantities of data, and do so very rapidly, and without a great deal of code. I’ve always been amazed at the raw power in this tool. Think of a […]

Systemd and non-desktop scenarios

So we’ve been using Debian 8 as the basis of our SIOS v2 system. Debian has a number of very strong features that make it a fantastic basis for developing a platform … for one, it doesn’t have significant negative baggage/technical debt associated with poor design decisions early on in the development of the system […]

And this was a good idea … why ?

The Debian/Ubuntu update tool is named “apt” with various utilities built around it. For the most part, it works very well, and software upgrades nicely. Sort of like yum and its ilk, but it pre-dates them. This tool is meant for automated (e.g. lights out) updates. No keyboard interaction should be required. Ever. For any […]

new SIOS feature: compressed ram image for OS

To wit: root@ucp-01:~# ls -alF /var/lib/docker/devicemapper/devicemapper/ total 52508 drwx—— 2 root root 80 Jan 29 22:38 ./ drwx—— 4 root root […]

#Perl6 compiler betas are ready

Ok … I am … well … blown away. I had thought Perl6 would be the Duke Nukem forever of programming languages. Indeed, it has been in active development for more than a decade. But you can download compilers (yes, you heard me right, compilers) for it now. You might say “why perl” or “why […]
