pensono··on Launch HN: TesterArmy (YC P26) – Agents that test web and mobile apps
Love using tester army to validate PRs against my preview environment. Skips the manual check much of the time and helps me ship more confidently.
pensono··on Reflect – Multiplayer web app framework with game-style synchronization
This technique is pretty similar to Operational Transformations, except that it requires an authority for serialization and must re-apply any state which is out of sync.
pensono··on F’: Flight Software and Embedded Systems Framework
Is C++ complex enough that it is difficult to model, and therefore hard to apply in formal methods?
pensono··on Why Use an FPGA Instead of a CPU or GPU?
FPGA latency is also much more predictable. Since you have cycle level control, you can know exactly how long any given operation will take. In a multi-threaded CPU, it's likely that the operation may be interrupted or delayed because of another process using the same resourt.

It's also worth noting that FPGAs are often much closer to the I/O than a CPU on a motherboard. Pin to pin latencies are much reduced in a situation where direct access to I/O is available. An Ethernet stack can sit on the same silicon without having to serialize data between the CPU and the north bridge.

pensono··on What happens before main() is executed in C and why is it important?
This article seems to be targeted toward embedded programming, so global state isnt that big of a deal because you have complete control of the chip. It's quite common to not even have threads or an operating system at all.
pensono··on Unilever threatens to pull its ads from Facebook and Google over 'toxic content'
American grocery stores have been doing this for a long time as well. Often their products taste better too because they use less added sugars and preservatives.
pensono··on Audacity 2.2.0 Released
Have you tried bitwig? It's fairly new and seems to do alot of things right.
pensono··on Can FPGAs Beat GPUs in Accelerating Next-Generation Deep Learning?
I have a feeling that much of the cost is from the smaller market. It takes a massive amount of engineering resources to put out a new chip, and you need slot of sales to compensate. If FPGAs become commonplace in servers, then we will see a price decrease as it becomes easier to recouperate the overhead.
