September 12th - Linux on the Laptop 2017: A System76 Out-Of-Box experience

by Allan Cecil

Topic: Linux on the Laptop 2017: A System76 Out-Of-Box experience When: Tuesday September 12th, 7:30 PM to 9:00 PM Speaker: Allan Cecil Location: O'Reilly Media, Sebastopol CA in the Tarsier conference room past the metal statue and to the right ( http://nblug.org/locations ) Description: You've probably heard of the mythical "Year of the Linux Desktop" for quite some time by now with the year seemingly always just around the corner. With Linux just now crossing the 3% install base threshold we may not be "there" yet but that's not to say there aren't some great companies out there making Linux-specific hardware. Case in point is the topic of this talk - System76 (http://system76.com) ships laptops in a range of sizes and configurations with Linux preloaded. In this talk, I'll demonstrate a new System76 Oryx Pro laptop and show off the current Out-Of-Box experience as well as their plans for their own distribution named Pop!_OS which is now in development. I'll talk about what works well with their current software loadout and areas that still need improvement. I'll also give an overview of the current state of driver support and touch on how that support dictated the hardware build of the laptop. I'll leave plenty of time at the end for everyone to get some hands-on time as some things (such as what the keyboard and button layout feels like) can't be demonstrated well from a projector.

NBLUG May 9th - Sex, Secret and God: A Brief History of Bad Passwords (Kyle Rankin)

by Allan Cecil

Topic: Sex, Secret and God: A Brief History of Bad Passwords When: Tuesday May 9th, 7:30 PM to 9:00 PM Speaker: Kyle Rankin Location: O'Reilly Media, Sebastopol CA in the Tarsier conference room past the metal statue and to the right ( http://nblug.org/locations ) Description: Most of what we've been told over the years about what makes a good password has been wrong, so it's no surprise most people pick bad passwords. This talk will cover the history of password policy and password cracking starting from the days when Richard Stallman hacked the passwords forced on his MIT computer lab because he considered passwords an authoritarian method of control. Next I'll discuss the golden days of password guessing featured prominently in movies like Hackers and WarGames. Then I'll move to the tech boom and the introduction of draconian IT policies like password rotation and password complexity and the dirty little leet-speak password secrets they led to. As we get closer to the modern day I'll discuss the "correct horse battery staple" password renaissance and more modern approaches to password cracking spawned by tools like oclhashcat and giant password databases dumps like the RockYou hack. I'll finish up with modern attempts to fix the password auth problem such as new approaches to secure password generation in password managers or schemes such as diceware as well as cover password auth reinforcements like the different forms of 2FA (including U2F) and Facebook's new approach to "I forgot my password" workflows. By the end everyone should have plenty of ammunition to take back to their IT department and get rid of those horrible password policies.

NBLUG State of the LUG 2017

by Allan Cecil

Greetings, As President of the North Bay Linux Users' Group I wanted to take an opportunity to get back to sending State of the LUG updates (I did not send a 2016 update). The goal of this E-Mail is to update all members about our current status in all areas of importance and to encourage further discussion about the future of NBLUG in the Talk list. Here are some TL;DR numerical highlights about the state of NBLUG as of 2017-04-20: 454 E-Mail addresses are subscribed to the NBLUG Announce list 259 E-Mail addresses are subscribed to the NBLUG Talk list IRC activity in #nblug on Freenode remains strong 6 of 6 board seats are filled through November 2017 NBLUG as a non-profit now owns a 720p projector thanks to donations $165.73 is in the NBLUG cashbox secured by our treasurer Important information: Please contact us at speakers(a)nblug.org if you know of someone who would be willing to present on a Linux or open-source related topic. NBLUG general meetings are consistently held on the 2nd Tuesday of every month at 7:00 in O'Reilly's Tarsier meeting room at 1005 Gravenstein HW N. in Sebastopol, CA past the metal statue and to the right. O'Reilly (http://oreilly.com) additionally sponsors NBLUG by frequently providing raffle books (in both e-book and physical form) for attendees as well as a free book of of a speaker's choice if they request one. Sonic.net (http://sonic.net) sponsors NBLUG by hosting our racked http://nblug.org server in their Santa Rosa datacenter. On behalf of the board, I would like to again publicly thank our sponsors for their continued support which enables us to operate without ongoing membership dues or donation drives. NBLUG Board: The current board as elected during the November 2016 general meeting consists of: Allan Cecil (President) E. Frank Ball III (Vice-President) Robert Thille (Scribe) Matt Da Silva (Treasurer) Tom Most (Board Member at Large) Matt Smith (Board Member at Large) Our next scheduled elections will be during the November 2017 meeting where all 6 1-year term seats will be open for nominations per our bylaws (http://nblug.org/bylaws/). IRC channel: NBLUG has an IRC channel at #nblug on the Freenode network (http://chat.freenode.net) that now sees daily activity and has grown to exceed the level of activity on the talk mailing list. Cash balance: The NBLUG cashbox currently contains $165.73 as last audited 2017-02-21 when the balance was confirmed by our Treasurer and holder of the cashbox, Matt Da Silva. Last year we received a number of donations that allowed NBLUG (via our Vice President, Frank Ball) to buy a 720p DVI/HDMI projector and the current cashbox balance reflects what was left over after the purchase. Thank you to everyone who donated to made this possible. Because O'Reilly generously sponsors NBLUG by providing us with a room to meet in and Sonic.net provides hosting for our website our expenditures are effectively non-existent. There are currently no expenditures the board can foresee in the near future and thus we are not currently seeking donations. Additional opinion and analysis: I, Allan, feel that the evidence above points to a viable and stable user group that is gaining new members at about the same rate that past members move on. Our best attendance happens when we have outside speakers and I will continue to work with the board to seek out speakers who can present on topics that would interest you, the members of NBLUG. While the board actively pursues this goal independently, I feel the best resource we have is the connections that members of the group have. Please let us know about potential speakers at speakers(a)nblug.org and we will promptly follow up with them. I encourage everyone to share their thoughts about this State of the LUG 2017 update on the talk list and I look forward to a lively discussion. Thanks, Allan Cecil President, North Bay Linux Users' Group A.C. ******

April 11th: Let's Encrypt on an nginx reverse proxy (Allan Cecil)

by Allan Cecil

Topic: Let's Encrypt on an nginx reverse proxy When: Tuesday April 11th, 7:30 PM to 9:00 PM Speaker: Allan Cecil Location: O'Reilly Media, Sebastopol CA in the Tarsier conference room past the metal statue and to the right ( http://nblug.org/locations ) Description: Let's Encrypt is a way for anyone to enable TLS (as in, HTTPS) support to a webserver at no cost. However, there are many security considerations involved with everything from certificate renewal to safe handling of the various files involved. In this talk and live demo I'll cover how to create a reverse proxy using the nginx webserver that simultaneously allows multiple webservers to exist at one IP address and show how isolating Let's Encrypt to a different system increases security. The talk will also cover more secure (and less risky) methods of automatic key renewal than the official, somewhat invasive renewal tool.

March 14th: Logo and the ContinuingLogo interpreter (Andru Luvisi)

by Allan Cecil

Topic: Logo and the ContinuingLogo interpreter When: Tuesday March 14th, 7:30 PM to 9:00 PM Speaker: Andru Luvisi Location: O'Reilly Media, Sebastopol CA in the Tarsier conference room past the metal statue and to the right ( http://nblug.org/locations ) Description: ContinuingLogo is a recently written interpreter for the Logo programming language that is still in pre-alpha. It is mostly compatible with Brian Harvey's UCBLogo interpreter and has some graphic and sound features inspired by Atari Logo for the Atari 800. Logo was created at MIT and BBN in the late 1960s as a language to support children in learning mathematical and logical thinking. It's most well known feature is turtle graphics, in which a "turtle" moves around on the screen as instructed, drawing a trail behind it. This talk will consist of a brief tour of some of ContinuingLogo's basic features, followed by demonstrations of several short example programs. Language demos will include an incredibly short pig Latin translator. Graphics demos will include spirals, fractals, line followers, and a traffic simulation. Sound demos will include the generation of music and sound effects, and illustrations of the relationship between sound frequencies and perceived musical notes. A few larger games will be demonstrated but not discussed line by line.

NBLUG general meeting Tues Jan 10th

by E Frank Ball III

North Bay Linux User's Group General Meeting: When: Tue Jan 10th, 2017 07:30 PM to 09:00 PM Speaker: Robert Thille Location: O'Reilly Media, 1005 Gravenstein Highway North, Sebastopol Topic: Linux in an Altoids Tin? It used to be that to run UNIX you needed a room full of computer and guys in white lab coats to manage it. Then, along came Linus Torvalds who wrote Linux, a UNIX-like os for his 386. He open sourced it and it was off to the races. Now Linux (and other UNIX-like OSes) run on all kinds of hardware; from super computers to your phone or even smaller systems. Some are even designed to fit in an Altoids tin. This talk will go over some of your options for running Linux on SBCs (single board computers), why you might want to do so, and how to get started. See you there, E. Frank Ball III Vice President, North Bay Linux Users Group Frank(a)NBLUG.org

Dec. 13th: Shareable Remote Linux Engineering Environments

by Allan Cecil

Topic: Shareable Remote Linux Engineering Environments When: Tuesday December 13th, 7:30 PM to 9:00 PM Speaker: Allan Cecil Location: O'Reilly Media, Sebastopol CA in the Tarsier conference room past the metal statue and to the right ( http://nblug.org/locations ) Description: Working on an engineering project with more than one person is hard enough when everyone is in the same room. It's more difficult when you have a team spread around the world and even more interesting if you're working on a shared physical device. In this talk, I'll discuss a remote engineering environment I created that allows contributors to connect to a standard Linux user account with a shared terminal (tmux), shared desktop (x2go with desktop sharing enabled), power and data control for a device under test (serial over USB), and even streaming video for viewing camera feeds (RTMP streaming from OBS Studio and viewed in VLC). This wide-ranging talk is appropriate for all levels of experience and will primarily be a series of live, remote demos.
