| BlogOver the past few decades, technological advances took our everyday life by a storm. As computers become smaller and cheaper to manufacture, we find ourselves increasingly dependent on software applications – even in the most unexpected life areas. This trend will continue – while new discoveries push the frontier of miniaturization, more branches of science will soon recognize and take advantage of this breakthrough approach.

Proxmox VM Watchdogs
Despite substantial investments in HA infrastructure, Proxmox cluster could still be vulnerable to services interruptions caused by unstable guests. There is one great feature provided by KVM that can help minimize the effect of such incidents. Continue reading “Proxmox VM Watchdogs”
ARI Transcoding Trap
During my recent experiments with ARI stress testing, I’ve noticed that despite making all the right decisions for the most part, it does come short in certain specific situations and relies on the programmer to provide the missing bit of intelligence. Continue reading “ARI Transcoding Trap”
PyCharm VirtualEnv ZSH Terminal
Despite numerous requests from thier userbase, JetBrains has yet to implement automatic virtualenv activation in the integrated Terminal window when in a project view. This post shows how to achieve this goal using zsh & Mac OS. Continue reading “PyCharm VirtualEnv ZSH Terminal”
eGPU 3D Acceleration
For CUDA-based software, like PG-Strom, putting a GPU in a Thunderbolt enclosure is enough. However, to ensure that regular 3D apps also benefit from this desktop-class acceleration, some extra steps are required. Continue reading “eGPU 3D Acceleration”
CUDA on Thunderbolt eGPU
To fully benefit from CUDA, PG-Strom requires certain capabilities not provided by mobile chipsets. We have to equip our Mac with full-featured desktop version of an Nvidia GPU. Continue reading “CUDA on Thunderbolt eGPU”
PG-Strom on Mac OSX
Installing pg-strom on Mac requires a few hacks, mostly related to CUDA files. In this article I will present a step-by-step process that will allow you to harness the power an Nvidia GPU and significantly speed up PostgreSQL queries on your Mac. Continue reading “PG-Strom on Mac OSX”
Scaling Up ARI
In my recent post I’ve shared my excitement about the new Asterisk API called ARI. Today I am going to show an example of a real life application of this technology when being used as a foundation for an integrated call center software. Continue reading “Scaling Up ARI”
Television Extraordinaire
This article serves as a (regularly updated) reference point that lists all the TV shows I found entertaining over the past few years. They are grouped based on the length of a single episode. The ones in bold I was particularly fond of. Continue reading “Television Extraordinaire”
Distributed Telephony with ARI
I have been working with VoIP systems for over a decade. My original experience was with wholesale exchange platforms, focused on high volume LCR. I designed and implemented numerous bespoke applications that provided convenient, web-based controls to a variety of underlying SIP servers. Continue reading “Distributed Telephony with ARI”
