schestowitzOne of the favourite anti-Open Source myths of proprietary software companies is that Open Source is unsupported and that there’s nobody to turn to for your organisations needs. Mark’s talk will reveal this FUD (‘Fear, Uncertainty, Doubt’) as the nonsense that it is, and show exactly how organisations using Open Source, the support ecosystem, and the underlying projects themselves interact to provide a level of support for Open Source Jan 25 05:23

schestowitzUsing detailed case studies, anecdotes and over a decades experience on the front-lines of Open Source uptake, this talk will give you the information you need to know to confidently deploy enterprise-class Open Source in your own organisation.Jan 25 05:23

schestowitz                                        <p>The Arduino Cloud is Arduino’s integrated platform to develop, deploy, monitor and control IoT devices with minimal effort. It enables makers, IoT enthusiasts and professionals to build easily connected projects based on a wide range of hardware including not only Arduino boards, but also ESP32 and ESP8266 boards. Arduino is committed to making all the Arduino Cloud features available to all the supported Jan 25 14:01

schestowitz                                    <blockquote>Jan 25 14:07
schestowitz                                        <p>The die photo below shows the 8086 microprocessor under a microscope. The metal layer on top of the chip is visible, with the silicon and polysilicon mostly hidden underneath. Around the edges of the die, bond wires connect pads to the chip's 40 external pins. I've labeled the key functional blocks; the ones that are important to this discussion are darker and will be discussed in detail below. Jan 25 14:07
schestowitzArchitecturally, the chip is partitioned into a Bus Interface Unit (BIU) at the top and an Execution Unit (EU) below. The BIU handles memory accesses, while the Execution Unit (EU) executes instructions. Most of the relevant circuitry is in the Execution Unit, such as the condition evaluation circuitry near the center, and the microcode in the lower right. But the Bus Interface Unit plays a part too, holding and modifying the program counter.</p>Jan 25 14:07

schestowitz                                    <blockquote>Jan 25 14:08
schestowitz                                        <p>If you frequent driving ranges, you’ve probably seen a machine (often attached to the front of an armored golf cart) designed to pick up golf balls. Because a driving range can easily fill up with thousands of golf balls an hour, such machines are necessary. After noticing that nobody wanted to pick up the ping pong balls after matches, Maxime Monsieur and his team (Oumaima Achkif, Reda El Marsse, and Jan 25 14:08
schestowitzAmir Farbod) built this robot that collects ping pong balls using a mechanism similar to those used for golf balls.</p>Jan 25 14:08

schestowitz                                        <p>FOSDEM is right around the corner, and finally in person after long years of dealing with COVID. I’ll be there again this year, and I’m looking forward to it! I have four slots on the schedule (wow! Thanks for arranging these, FOSDEM team) and I’ll be talking about several projects. There is a quick lightning talk on Saturday to introduce Helios and tease a full-length talk on Sunday, a meetup for the Jan 25 14:19
schestowitzHare community, and a meetup for the SourceHut community. I hope to see you there!</p>Jan 25 14:19
