Suggested Topics for Homebrew Con 2021
Suggested Topics for Homebrew Con 2021 The suggestions below have been outlined by the Seminar Subcommittee for Homebrew Con 2021. The topics suggested are not intended to be an exhaustive list, but rather a guide to potential speakers to some of the top priority topics that the committee would like to see presented on at this year’s event. Hopeful speakers are welcome to submit proposals beyond the scope of these suggestions but are encouraged to keep them in mind when planning their proposal content. Beer Styles The BJCP recognizes over 130 distinct beer styles in its beer guidelines, along with countless others not in the guidelines. Each style has a unique history and characteristics and is brewed using specific brewing processes and techniques. The seminars in this track will highlight individual beer styles and the techniques used to brew them (and why). • How styles emerge (Ex: Kolsch/Alt, Regional International Ales [Argentina, Italian, New Zealand, Brazilian, etc.]) • Compare and contrast of similar styles • Differentiating general history from beer history • Emerging styles (Ex: pastry stouts/ fruit “slushies”, Winter Warmers, etc.) • How to decide where your beer goes in a competition • Saison • Bocks (history, sub-styles, brewing requirements, etc.) • How taxes, water chemistry, wars, technology and/or climate defined beer styles • Extinct (or nearly extinct) Styles • Historic beers (Ex: Stein Bier, Fraoch, Herbal, Wiccan ales, Egyptian ales) • Lager fundamentals • Best ways to educate yourself about a style - • Beer Vocabulary and what it all means ASBC (anyone?) • Belgian Styles (in general) – challenge to brew, make it taste like it’s from Belgium • How to brew authentic English Pub Ale • Fresh Hop Beers • Mead styles (Ex: Polish, historical meads, other) • How to achieve the style you are looking for (Expectations of what you want vs. -

A Letter to the FCC [PDF]
Before the FEDERAL COMMUNICATIONS COMMISSION Washington, DC 20554 In the Matter of ) ) Amendment of Part 0, 1, 2, 15 and 18 of the ) ET Docket No. 15170 Commission’s Rules regarding Authorization ) Of Radio frequency Equipment ) ) Request for the Allowance of Optional ) RM11673 Electronic Labeling for Wireless Devices ) Summary The rules laid out in ET Docket No. 15170 should not go into effect as written. They would cause more harm than good and risk a significant overreach of the Commission’s authority. Specifically, the rules would limit the ability to upgrade or replace firmware in commercial, offtheshelf home or smallbusiness routers. This would damage the compliance, security, reliability and functionality of home and business networks. It would also restrict innovation and research into new networking technologies. We present an alternate proposal that better meets the goals of the FCC, not only ensuring the desired operation of the RF portion of a WiFi router within the mandated parameters, but also assisting in the FCC’s broader goals of increasing consumer choice, fostering competition, protecting infrastructure, and increasing resiliency to communication disruptions. If the Commission does not intend to prohibit the upgrade or replacement of firmware in WiFi devices, the undersigned would welcome a clear statement of that intent. Introduction We recommend the FCC pursue an alternative path to ensuring Radio Frequency (RF) compliance from WiFi equipment. We understand there are significant concerns regarding existing users of the WiFi spectrum, and a desire to avoid uncontrolled change. However, we most strenuously advise against prohibiting changes to firmware of devices containing radio components, and furthermore advise against allowing nonupdatable devices into the field. -
Home Automation for Tinkerers
Home Automation for tinkerers Abílio Costa [email protected] Once upon a time... Where it all begun ● I had 3 wireless power sockets! (yay?) ● But I was using only one. Why? ○ Only a single remote: ■ How to use the other two in different rooms? ○ They were dumb. ¯\_(ツ)_/¯ ■ It would be nice to have one of them turn on/off on a schedule? Poor man’s solution ● An Arduino Nano + 433MHz RF transmitter + RF receiver. ○ Total cost: less than 5€. ○ Arduino sketch using the RC Switch library. ○ USB to a Raspberry Pi for the brains. ○ Script on the Raspberry Pi; exposing HTTP endpoints. ● My home was now so very smart! ○ Control each power socket through my phone. ○ Office desk power turns on automatically when I get home. ○ Bedroom lamp turned on automatically after the morning alarm. ○ I could buy more power sockets, even from other brands! ● The same idea can be used to interact with many other things: ○ Alarm sensors; Doorbells; Garage doors; etc. Next step: home automation software Why? ● Better management (my script wasn't going very far). ● Allow integrating other devices besides the power plugs. ● Make devices from different brands / protocols talk to each other. ● UI included! Home automation solutions ● Open-source software: ○ Home Assistant ○ Domoticz ○ OpenHAB ○ Pimatic ● Commercial hardware + software: ○ SmartThings ○ Vera ○ Xiaomi Home Assistant Home Assistant ● Good looking and customizable web UI (uses Google Polymer). ● Lightweight; extra functionality added with a plugin-like system. ● Very powerful automation engine (IFTTT on steroids). ● Autodiscovery: many devices will just show up without any config! ● Local: no cloud dependency! ● REST API available. -

OpenSource Software in Mac OS X V. Zhhuta UK2 LImIted t/a VPS.NET, [email protected] Max OS X stem from Unix: bSD. It contains a lot of things that are common for Unix systems. Kernel, filesystem and base unix utilities as well as it's own package managers. It's not a secret that Mac OS X has a bSD kernel Darwin. The raw Mac OS X won't provide you with all power of Unix but this could be easily fixed: install package manager. There are 3 package manager: MacPorts, Fink and Homebrew. To dive in OpenSource world of mac os x we would try to install lates version of bash, bash-completion and few other utilities. Where we should start? First of all you need to install on you system dev-tools: Xcode – native development tools that contain GCC and libraries. Next step: bring a GIU – X11 into your system. Starting from Mac OS 10.8 X11 is not included in base-installation and it's need to install Xquartz(http://xquartz.macosforge.org).
