December 8 Meeting Presentations Available

Craig Cook recorded the most recent TriEmbed meeting’s presentations about C Preprocessing with the Arduino IDE, custom tools for laser-cut acrylic enclosures, getting results from the T962/T962A reflow ovens, and a tool being developed to allow easy bicycle wheel truing.

After being crunched through Handbrake they’ve been put on Youtube. Details of these and past meeting archives are on the TriEmbed Meetings/Archives page.


(By the way: smart phones don’t appear to render the menu bar of the TriEmbed web site’s main page, turning the whole thing into a set of three parallel lines near the upper right corner of the page. Clicking on that drops the nested menus for meeting, email, project info, etc, that is more obviously available with a desktop browser).

New web/blog site ready to use

TriEmbed has a new home on the Internet. The URL redirects to a WordPress site now, which is a combination of web pages and a “web log posting” mechanism (via the “Posts” link) with support for arbitrary comment chains. I’ve copied the old content in and defined a few posting categories, etc.
Several of you got mail giving you accounts with “siteauthor” roles. This custom role has more privilege than “author” to allow creating web pages as well as postings, but less than “editor”, so you’re constrained to operate only on stuff you’ve created. Feel free to log in and try things out.
If I forgot or messed up the “initial list” I gathered last month (and which I extended a bit), my apologies. You’re starting out with a randomly generated password. Feel free to change it to something easier to manage, but select one judged by WordPress to be “strong”. Apart from staying polite and mindful of the children reading this list and viewing the site, we must keep it secure. The ISP for my personal domains and I have a happy relationship approaching its 15th birthday, but he’s a stickler about security. This site uses Akismet, Wordfence, and limited login plugins to keep the garbage at arm’s length, but WordPress sites are periodically BOMBARDED with high frequency breakin attempts as vulnerabilities are found and fixed. OK, I’m sure we’re clear about that.
If you just want to be able to log in and comment without the hassle of your comment going through the moderation process except the first tie, say the word (including your desired username) and I’ll give you a “subscriber” account with a minimum of fuss. Your first comment will block for moderation, but after being approved you’ll be able to comment freely.
If you’d like to create content but want help deciding if it should be published (or any other kind of help), request a “contributor” role.
I’m willing for anybody receiving this email msg from the list to have an account on the site. The type of account you can have relates to how well we know you and can trust you. Referencing a URL or three in the mail archive, reminding me (or the list: your choice) of roughly when you last attended a meeting, etc, will help (I knew those sign-in sheets NCSU requires us to keep might have some use some day!) Just drop me or the list a line with your full name, desired username and what role you’d like to start with and I or another admin will take it from there.
I’m happy to upgrade you to editor if you’d like to help develop the site beyond adding content (e.g. helping me fix foulups that step on accepted WordPress best practice). And if you’d like to share admin duties, please send me private email so we can discuss it (and thanks in advance!)
If there’s interest at the August NCSU meeting I’ll fumble my way through a short training session, with any and all help welcome.
We can make either the “posts” or “home” (web) page the default page for the site as we get a feel for what would be most useful.
This site is automatically backed up once a week, with a “ring buffer” of four backups.
(Thanks to Gayathri Jegan Mohan for showing me how Chrome incognito windows can be used to be on the same site with multiple identities. This saved me a lot of time!)
