C++ Dependency Management
I last did serious C/C++ development in 1999 while at GS, but since C++11 came out and
Bjarne Stroustrup came to work for Morgan Stanley I have wanted to pick it up again. One of the obstacles was that not only was my knowledge of the language out of date, but so was my knowledge of the development tools and build systems.
Since . . .
Groovy, FXML and dynamic layouts
This will be the first of a series of short articles on JavaFX, a worthy, underestimated successor to AWT and Swing JFC that probably came years too late to save Java desktop development from .NET and HTML5 but offers a clean rapid-development environment for the JVM:
- the Java API is a step up from Swing -- less verbose; better . . .

The Z800 Needs a Friend (And a Power Supply)
In the springtime the dual GPU setup did in more than one power supply, including both an 850W and 1100W. I finally reached the conclusion back in May that the combination of NYC local electricity costs and the recurring cost of buying refurbished power supplies made ETH mining . . .

Final build: Z800 workstation
The last couple of articles covered setting up a refurbished HP Z800 workstation for work on cryptocurrencies: adding RAID storage and putting in a pair of overclocked EVGA GTX 980 video boards to support GPU mining. The resulting machine is probably more power hungry than the ideal rig, but another way . . .
A computational home heating system
The replacement power supply -- the Z800's third one now -- arrived while we were on holiday, and so far seems to be running better. I decided to put it to the test by mining Dash and Ethereum in order to learn more about the mining process.
Running some numbers, one thing is clear: mining Dash at home with a GPU is a good way to . . .
I decided to start over with a plain Debian install after wrestling with Solaris x86 and taking a break from coding at home. I hit the power button, which flashed briefly and then ... nothing, shut down. Reseated the PSU, and again no joy. Checked for bent pins or something dumb like a loose plug and all seemed fine.

Low-latency messaging library
Martin Thompson's Strangeloop talk is worth watching for anyone interested in high-performance Java. Like Peter Lawrey's Chronicle Queue, Aeron's foundation is a low-latency append-only log, but even more ambitious. It is media-agnostic and --like ZeroMQ -- meant to be portable across languages, and he envisions supporting . . .
