Hi all. We've had poor attendance recently, and other events I've scheduled for this holiday season have been called at the last minute because nobody coming.

So, if people don't tell me, either here, on the Meetup or via email, that you're planning to attend Monday's meeting, I will scratch and say "See you next year".

Two cutting-things questions.

I have a Pyrex test tube that was cleared out of the lab a while ago. We don't use such glassware anymore. I've taken to use it as a tone bar for my lap steels, but it's about 8" and I need it at about 4". You cannot cut Pyrex as easily as you can glass, which in normal circumstances is a feature, not a bug. I want to cut down the test tube and have a clean, hand-safe result at the end, without spending too much on gear. Ideas?

Similarly, I have a Partscaster guitar. I would like to cut an expired license plate to serve as a pickguard, and want a hand-safe result. I don't have access to many power tools. I am imagining spending an afternoon with a hacksaw and ending up with a far-from-aesthetically-pleasing result.

The Visual Studio editor is open source now. So's .NET Core 5, and it's supposed to be useful for Windows, Linux, and OS X. What a world.

Visual Studio Pro has a subscription model now, which I imagine isn't that different from having an MSDN subscription. Still more expensive than Vim, so I probably won't be ordering any time soon.

Communication with my connection inside MongoDB indicates that the problem is that the backup file contains several BSON documents within it, and my code was trying to read it all as one.

It is reasonably easy to read a file containing several JSON documents and discern that it contains several JSON documents that must be separated before parsing, but as BSON is a binary representation, it is less so.

My team at Google has been very big proponents and innovators of USB Type-C. I've worked on two Pixel products now that use the connector and its related technologies (Power Delivery, Alternate Mode, USB 3.1). It really is an amazing little connector.

However, now that there are more and more Type C products rolling out from Nexus, One+, Nokia, and more, this I have found painfully true : USB Type-C will only be as good as its ecosystem, and more specifically, the worst of its ecosystem.

I have started reviewing USB cables on Amazon because I have gotten fed up with the early cables from 3rd party vendors that so blatantly flaunt the specification and I want to hold them to task.

You may not just get weird behavior from your devices with these bad cables... What some these vendors are doing is downright dangerous.

I've been contemplating setting up a blog where I document bad cables and perhaps give some insights into USB Type C as well.

While waiting for the Android APK to update, I put my Guitr code into my "Hello World" Cordova app. I trigger things wrong; I have "onchange:draw()" in my HTML tags rather than putting the triggers in my JS file. I think I'd better learn to do this in raw JS rather than importing jQuery.

Still, I consider this a win.

Have a program that determines what a directory's ACLs should be, then uses a syscall to have setfacl do that. 

I had been letting setfacl handle the recursion, but we've decided that enough active stuff happens, stuff that generated LARGE DATA, that handling the recursion myself is to be done. And this includes symbolic links.

I just rebuilt Rakudo to get the newest Perl 6, and rewrote that thing in Perl6, trying to use the same algorithm as before.

My Perl 6 takes an hour and a half.

And I can't identify egregious errors in the thing.

"Netflix Switch” Home Automation #IoT
http://ift.tt/1P5eGIn

Netflix wants you to build your own home automation electronics in order to automate at least the first half of “Netflix and chill” with their Make It campaign showing you how to build a wifi remote that automatically adjusts lighting, silences your phone, orders takeout, and of course, queues up your entertainment. The prototype shown uses a Particle and IR LED, and instructs makers to reverse engineer their TVs IR remote signals using Ladyada’s classic tutorial. What I like about this ad campaign is that it encourages people to make their own electronics projects from an accessible and fun angle.

First, there was a Shakespearean Insult Generator, which was three lists of words to throw together randomly.

That was insufficiently generator, so I put it into Perl.

Now, I wanted a simple thing to test my REST framework with, and I had this code sitting around.

It's internal for the moment, but I could easily put it somewhere accessible, allowing one and all to call each other "thou puking rough-hewn wagtail" or the like.

Found this from +Eric Topol​'s Twitter feed.

Leptin is a hormone produced by the adipose tissue that acts in the brain, stimulating white fat breakdown. We find that the lipolytic effect of leptin is mediated through the action of sympathetic nerve fibers that innervate the adipose tissue. Using intravital two-photon microscopy, we observe that sympathetic nerve fibers establish neuro-adipose junctions, directly “enveloping” adipocytes. Local optogenetic stimulation of sympathetic inputs induces a local lipolytic response and depletion of white adipose mass. Conversely, genetic ablation of sympathetic inputs onto fat pads blocks leptin-stimulated phosphorylation of hormone-sensitive lipase and consequent lipolysis, as do knockouts of dopamine β-hydroxylase, an enzyme required for catecholamine synthesis. Thus, neuro-adipose junctions are necessary and sufficient for the induction of lipolysis in white adipose tissue and are an efferent effector of leptin action. Direct activation of sympathetic inputs to adipose tissues may represent an alternative approach to induce fat loss, circumventing central leptin resistance.

And what I think that means is: White adipose tissue is "belly fat". Activating neurons in the adipose tissue with light creates leptin, which starts the brain into breaking it down. "Necessary and sufficient" that this does it and to do it, it's all you need.

Which could be cool. I don't know how to make this work. Put an LED board on my stomach? Does hue matter? Would red light be more effective than blue? Clearly, none of that's in the abstract. I should see if I can get this full paper from Purdue libraries. Then, I should see if I can make heads or tails of it.

Oh God, spare me more discussion about Intellectual Property law. I know the basics: patent, trademark, copyright, trade secret, license. I've known for years, and barring a change like in Cambodia and post-Revolution France, they won't change. If they do, I'll be more worried that, as a person who wears glasses, I'd be considered ruling class and be cooked alive for food, and thus won't have to worry about infringing anything.

Over the last few months, we've ran an experiment, moving from 
Tuesdays over lunch in Whistler to Wednesdays after work at the
MatchBox, followed by GLOSSY Open Source Food & Beer & Chat at LBC.

We've learned several lessons (first: bring your own DANG HDMI 
cables to MB), and I certainly don't regret it, but from discussions
with Joe and Michael, we might do on-campus after-work, as we have
done before.

Or not.

So:
    Location -- MatchBox? WSLR? Some other building on-campus? 

    Time -- After work? Lunchtime? I'd suggest 7:30-8:30am if I
    thought anybody would go for it, but I sincerely doubt it.

    Day -- Wednesday was chosen to make the Mongers -> GLOSSY
    transition easy, but with campus not being quite as easy 
    walking distance from LBC, we might look into other days.
    Although, it's almost Tuesday, Wednesday or no-day for me.

Any comments at all about when would be a good or bad time to Monger
would be appreciated.

Joe Kline is presenting at PPW just before our expected meeting, 
and will re-present that talk for us next month, so that's on-deck, 
wherever and whenever it occurs.

Gave up on the Lenovo laptop that's been giving me problems since I got it, and got a low-end HP laptop to fill the gap.

A few things: by default, it's function-on, so hitting the F6 key is sound mute unless I hit the function key to make it serve as F6. Which is ... okay? I mean, I can see it either way.

Second, it didn't have onboard Bluetooth, but I have a BTLE dongle, and was able to have the FitBit live tile sync with my FitBit, meaning I can take the dongle home and connect it to my HTPC. Which is kinda win.

"While stuck by himself on the red planet, Watney is very literally the most isolated person to ever live—more than ten times more distant from any other human being than even the Apollo astronauts were when they visited the Moon."

When furthest away, the Moon is ~400,000 km away from Earth.

When closest, Mars is ~54,000,000 km away. 

That is more than ten times more distant, I guess.

Yes, this indicates that the major problem is infrastructure, that the cars themselves are solid but, like William Gibson says, the future isn't well-distributed.

Gas stations are currently for everyone, and are set up in neighborhoods for quick entry, quick use and quick exit. If everyone has a charger in their garage and topping off their cars every night, the gas station has no purpose most places, but near major roads, I could see large charging stations, dirt of on the truck stop model. If it takes several hours to max your battery, it'll be important to have something for you to do, for your bored children to do, for that time.

I think that, for daily commuter cars, electric vehicles are all but perfect, but we don't think of cars as specific tools like that, but as all-purpose gear, and it irks me to think that I could drive to with and back, no problem, but driving to Indy for a user group meeting or driving to the West to see family becomes unthinkable.

So, question becomes, does this mean the end of the cross-country car? The return of passenger train?

I have a #Perl module that uses Net::OpenSSH to connect to Globus Online to share directories full of scientific data. It covers the primitives well enough for work to move forward.

But I don't know what "move forward" means right now. 

Been thinking about making it into Net::Globus and putting it into CPAN, but it seems a bit more involved than I want for my first CPAN module. Also, I am not sure how you write tests against a service when you don't have authentication against the service at the testing stage.

So I don't know what to do right now.

Considering a new laptop. Since almost all of my entertainment needs are satisfied by my tablet and my Chromecast, this would be largely for development. Some writing, as I've been blogging more, but mostly development.

Here's what I think I want:

* 8GB Memory
* 128GB+ SSD - not sure how much more Plus, but at least some plus
* USB3 in at least one port
* at least 13" screen
* no optical drive 
* more brushed aluminum, less breakable plastic

I'm not sure if I want Core I7 or if Core I5 would do. I'm reasonably sure I don't want a touch screen: I touch my tablet's screen and it gets greasy and gross. I don't want that for a screen.

I like the idea of running OSX. It's a real Unix, descended from Ritchie and Thompson. I just think there's a $500 difference between the MacBooks I've seen and equivalent PC hardware, and I'm not sure what I'm getting for that. If someone else was paying for it, sure, I'll go for that, but not on my own dime.

Someone I know rocks a Dell XPS 13, and it looks right about what I want. I'm torn between running Linux and running Windows 10 on it. I know I could install Linux and put Win10 on a VM, but I've had problems trying to get developer tools running in a VM before.

So, what am I forgetting? What should I know?

I applied for a developer position, a position within a research facility in a university. I hope that this is a step up for me, but all I really know is from the description on the hiring site.

A contact, an associate professor, responded and asked me to prepare a fifteen-minute presentation discussing my suitability for this position. Given the one-sheet I saw, all I can really say about this position is that it involves dealing with handling data from human subjects and thus must follow HIPAA. I worked at a medical clinic earlier in my career, so I'm familiar enough for now.

I've gone through a number of interviews in my life, and this is the first time I've ever even heard of this as part of the interview process. I'm not too afraid of presenting itself -- I've given many presentations to user groups and the like -- but nothing in the job description says anything about presenting like this, so I'm not seeing it as anything to do with the duties of the position. This raises red flags with me.

Is this a thing, just not a thing I haven't heard about before?

(Evidently off-topic for programmers.SE, and seems too specific for the suggested Workplace.SE.)

Was asked what language someone should learn first if learning how to program.

I have three answers: 

1) It's like asking what language you should learn if you're visiting Europe. It all depends on where you're going.
2) Church and Turing say that, if you can do a thing in one language, you can do a thing in any language. It kinda doesn't matter.
3) Right now, the only place where you can't use Javascript is in operating systems work. It's a comer in back-end web work. It's a first-class player for Win10 applications work. Johnny Five means you can use it to write Arduino code. And you don't need to install anything: you can use your browser and Notepad. So, might as well learn Javascript.

Love the video, love the series.

Argument I've heard is that the idea of freedom of the skies, that national sovereignty didn't extend into space, wasn't clear yet, so the US wanted the USSR to go first, so that precedent was set via Sputnik and spy satellites could fly over Russia with impunity.

Of course, lots of rockets were blowing up on the pads, too.

"If you don't know why it is there, I won't let you remove it. If you can explain why it is there, then I'll let you remove it."

What I have (and the inverse):

    receive a possible unix username
    put unix username into database if valid
    return username.is_valid && db.is_successful ? 1 : 0

What I need (and the inverse):

    receive a possible unix username
    put unix username into database if username.is_valid
    for ( list of directories shared to user's boss ) :
         set acl on directory for username 
    return username.is_valid && db.is_successful ? 1 : 0

But, I want to trigger the acl setting after the return, because the database call is fast enough for a user to wait, but the recursive crawl over a file system, setting an acl on every single file or dir, is too much of a thing to expect users to wait for.

Suggestions?

In this function, we're getting a directory, a user or group name, and a means to determine if it's a user or group.

sub set_one_acl {
    my ( $dir, $name, $is_user ) =@_;
    if ( ( -e $dir ) && ( 
         ( $is_user && check_valid_user($name) ) || 
         ( !$is_user && check_valid_group( $name ) ) 
         ) ) {
        ... action occurs here
        return 1 ; 
        }
    return 0 ;
    }

The tests individually work. Could be a symbolic link, so -e instead of -d. $is_user is a boolean. check_valid_user() and check_valid_group() use getpwnam and getgrent to be sure.

I hate that big if statement, though, but think nesting all that if would be worse.

This was sent to the mailing list and will also be on the GLOSSY meetup.

I think we all can say that the #1 takeaway from last night's meeting is to never trust an HDMI cable. That's fine; I have a LONG one I can bring from home for next time.

I have an idea for a "ring Dave for entry" web-app that'd connect to me. I think it might work well with a QR code, except I generally think QR codes outside of very specialized environments are like "fetch" from Mean Girls; never going to happen.

Thanks to Joe Kline for showing us XPath-style HTML parsing with
XML::LibXML. I'm of at least three minds about parsing:

    * Much of my parsing is simply regular expressions in part
      because I want it now, I don't need it to last
    * I still have code subclassing HTML::Parser, and as long
      as it gets my xkcd and CommitStrip comics for me, I'm happy
    * I work enough with jQuery that using CSS selectors
      is my go-to for writing new code
    * Everybody should be exporting everything in JSON anyway

Four minds. I'm not schizophrenic, I'm quadrophenic! Still, using XPath is a reasonable way of doing it, too. Do you have example code we can look at, Joe?

Thanks to Mark Senn showing us some interesting parts of Perl 6, set for official release before this Christmas but available for testing now.
(http://ift.tt/1I5Buq2) I have it running thanks to rakudobrew, but haven't done much more than used Mark's rewrite of my password code on it.

Thanks also to Broc Seib for reserving the room and finding the one non-crappy HDMI cable in the MatchBox.

There are several open questions for next time:

Did the all-technical talk at MatchBox followed by social time with GLOSSY at LBC work for everybody? Should we stick with that or go back to WSLR?

Is there a topic anybody desperately wants to present for next time?

Superficially ugly code is irrelevant. Pretty formatting--or lack thereof--has no bearing on whether the code works and is reliable, and that kind of mechanical fiddling is better left to an automated tool.

http://ift.tt/OKXTdu

I disagree with the beginning, but not the end. Programs are messages that we write to future maintainers that also are executed, and superficially ugly code is also unreadable messages. If it really works and is reliable, we read the messages less often, but being able to read and understand it is important.

To some extent, yes, you can automate that. I tend to run PerlTidy a lot on my code, with my own ideosyncratic Perl style, neither K&R nor GNU, which some people hate. (Use your own .perltidyrc if you must!) But you can put unclear, ill-considered, incoherent ideas into grammatically-correct sentences full of spell-checked words. That doesn't mean the message makes sense.

At first, I didn't contribute to #CPAN because I didn't know what I was doing and my Perl Fu was not strong.

Then, about everything I'd want to put into a module was either very specific to my local environment or already existed.

Now, I believe I can do it, and I know there's nothing in CPAN for Globus. It's likely going to scratch my itches, when I get it more fully-formed.

I have perlmod and perlmodlib opened and I will be reading them. I have the PAUSE account. Other things (besides filling in a LOT of functions and fuller POD) I need to do before this becomes Net::Globus?

Dear American Internet,

We already went through this in the 90's.  I can still put an algorithm in a few lines of code on the front of a t-shirt that is virtually unbreakable to anyone, including the government.  Let's not revisit the discussion, because the answer hasn't changed.

Another controversial programmer opinion:

SQL is code. Treat it as such.
That is, just like your C#, Java, or other favorite object/procedure language, develop a formatting style that is readable and maintainable. I hate when I see sloppy free-formatted SQL code. If you scream when you see both styles of curly braces on a page, why or why don’t you scream when you see free formatted SQL or SQL that obscures or obfuscates the JOIN condition?

Entering into the fun of ACLs in Linux. I might start saying "Aye See Elles" because "Ackles" is such an ugly word.

It's my understanding that Windows ACLs are very fine-grained, with things like "view a directory" and such opened out. With Linux, it's read-write-execute again but with finer grain. You can allow group X to access a directory, but you can disallow people who are also in group Y, or use Z who would otherwise have access. 

15 years or so after I first started hearing about them, I finally have a practical reason to play with them.

I've recently been reminded that we haven't been letting people know
that the group is available to help with

* general Perl
* general programming
* troubleshooting program problems
* design review and help
* presentation review
* (other things I can't think of right now)

We have always been happy to answer questions, but I had gotten out of
the habit of reminding people.

Depending on your problem and inclinations, we can provide help either
individually or as a group. All you have to do is ask.

#Javascript  deployment question: When I write a lib, say foobar.js, I put it in my HTML as

#Javascript  deployment question: When I write a lib, say foobar.js, I put it in my HTML as <script src="foobar.js?reload"></script>, which codes it as dynamic and downloads it again each time.

I'm finding points currently where a user is having a problem with a web tool I wrote, so I come up, hit Ctrl-Shift-R and it works. But changes shouldn't be like that.

So, I think that, while I'm developing, it can be foobar.js?reload if I need, but when it's ready to go, I should call it foobar-1.23.js. 

Or, perhaps foobar-1.23.min.js. All this started up when I started playing with yui-compressor this morning, so that's a think I'm looking to do again.

tl;dr - Google+ to Twitter explained.

At last night's Food & Beer & Chat for +Greater Lafayette Open Source SYmposium (GLOSSY) , it was mentioned that I have all my G+ posts automatically going to Twitter. Today, it struck me that I had forgotten how I had set that up.

Which is: I wrote a tool that took someone's public feed from Google Plus and turned it into an RSS feed, and used +IFTTT to tweet from there. Yes, I most certainly could've gone the rest of the way, tweeting instead of posting, but I think the problem is not tweeting the same post twice. IFTTT solved that one for me.

I've been critical of Satch-and-Vai-lead jams, because they get filled with the flurry of notes that each guitarist is capable of. Here, BB King's "The Thrill Is Gone" is nothing I'd expect from Steve, Joe, Tobin, Skwisgaar/Brendon or Mike, but they all did it justice.

Thought occurred to me on the way to work this morning: In fiction, there are cool powerful people where people have parts of their body replaced by technology, with the 6 Million Dollar Man being a perfect example. In reality, no replacement is going to be as functional as the original part, and while mechanical muscles may be more powerful than biological muscles, the cool arm is going to be connected to a normal skeleton, so it can't lift a car. So, you only get a bionic thing if the biological thing is utterly nonfunctional either by defect, age or trauma.

The Singularity/Post-Human dream is digitizing the human brain. Per Kurzweil, at first it'd be a destructive process, requiring the material being scanned to be torn apart piece-by-piece. Who would be willing to go through this process? People whose physical bodies are nearing end stage anyway, by defect, age or trauma. 

The more technology removes accidents and connectedness eliminates ware, the less trauma will be a factor. The more medicine advances, the less defects will be life-threatening. This means that the first people who will be digitized humans will be the elderly.
 
Now, what to do with that....

Head-to-Head Web Scraping with Perl: Mojo::DOM vs Web::Query

+Joe Kline told me about this. We're looking to have a talk at Purdue Perl Mongers about web scraping, comparing this style to XPath and maybe Mojo::DOM. Thank you, TPF and Sawyer X.

I'd say to next year's YAPC::NA team, presenters should make their slides public, the links should be in the video description beforehand, and the cameraman should therefore focus on showing the presenter, unless live coding happens. Maybe bring in the slides in post? Watch a few JSConf videos. I know they have $$$$ to make it look good, but even at the level we're at, we can step it up a notch.

Considering Kurzweillian mental digitization and upload. 

There's a story by Harlan Ellison called "How's the Night Life in Cissalda" where a returning astronaut returns to Earth with an alien parasite that binds to a host sexually. They separate him, but eventually, it splits and connects to the rest of intelligent life on Earth (humanity on down), but the astronaut, having been separated, remains rejected.

If my brain is non-destructively scanned and modeled into Cyber Dave, it could engage in a massively-beyond-massively-multiplayer online game as core reality, GTA with infinite lives and no consequences. The Matrix where everyone is Agent Smith. Or it can connect to a body and engage with the old and slow real world.

That is where Meat Dave, augmented or not,  could only be a visitor.

I'm seeing it as a massive fork of humanity, and the part that isn't will feel like they're stuck at the velvet rope, denied access to the incredible party that is the future.

Haven't seen Aloha, but by description, it remind me of his earlier Elizabethtown. In that one, the lead is a wunderkind whose project who went downhill and brought him with it, but was appreciated long after the initial release. I think he thought the movie would follow the same arc, and it just hasn't. Every trailer I've seen shows me Elizabethtown in Hawaii, and I don't want to see that.

Testing AJAX APIs with Perl

I have data that I need for a web page. I have three sources for this data:

1) program that reads from the database and exports the output as JSON
2) program that checks a checksum, regenerating and exporting if necessary but just exporting most of the time
3) static file generated every 15 minutes, which means that, should the source change (rare but it does happen) the cache will be out of date for up to 15 minutes

#3 sucks, but it is the fastest. Looking at developer tools, #2 is only slightly faster than #1, according to the waterfall in Chrome's dev tools, which run once on reload, but the program I wrote using Perl, Benchmark.pm and LWP, which hits each point 200 times, puts #2 as closer to #3.

I get that Benchmark does not behave like Chrome dev tools, so I need a tool that does web dev load testing but can repeat hundreds of times to get numbers that don't just say "Yeah, the file system hiccupped then." Help? #LazyWeb

I showed up a little early and waited until someone showed up. Lucas did -- he has a tablet with a busted USB port he wanted to ask y'all about -- but at about 7:10, I decided I had a busted taillight and family things to take care of and left.

I understand a number of you showed up later than that and were disappointed to find the locked door. 

I'm curious: How many of you showed up? And did my late announcement of the meeting on G+ have anything to do with that?

All of Unix history now on github "covering the period from its inception in 1972 as a five thousand line kernel, to 2015 as a widely-used 26 million line system. The repository contains 659 thousand commits and 2306 merges, created by synthesizing 24 snapshots of systems developed at Bell Labs, Berkeley University, and the 386BSD team, two legacy repositories, and the modern repository of the open source FreeBSD system."
...
Quite some analysis is presented on this page, and git allows further digging: "running git blame on the kernel's pipe.c file will show lines written by Ken Thompson in 1974, 1975, and 1979, and by Bill Joy in 1980"

Some of the earliest code was recovered by OCRing printouts!

"The data set can be used for empirical research in software engineering, information systems, and software archeology."

It's legit, too: "Although Unix was initially distributed with relatively restrictive licenses, the most significant parts of its early development have been released by one of its right-holders (Caldera International) under a liberal license."

"""I took a university course on Unix internals in 1988. The lecturer started by announcing "this is the last year that we will teach this course as Unix is now very out of date and is being left further behind every year". It turned out to be the best course I ever took.

That Roy Orbison shot was Bruce Springsteen backing Roy on Black and White Night. Only a slight mistake, but worth noting. The guitar duel between Bruce and James Burton is the reason I own that DVD.

On the one hand, Charlie Parker loved Country, said "listen to the stories", and I can't say I'm better than Bird. On other, I don't say I like the genre, but I like several artists within it.

Genre is audience and the chasing of, more than anything else. You mention Television; I took the fact that Dwight Yoakam played CBGB and survived as a sign that it was okay for me to enjoy it. Similarly, I took Eddie Martinez's crucial riffs on "Rock Box" as an okay to enjoy Run DMC as a teen. In these cases, I could expand my genre - teenage white guy <=> hard rock - to include country and hip hop due to demonstrable "rocking".

Tropes of genre are transient. The Carter Family's Country was mostly folk song from Britain. Jimmie Rodgers' Country was very close to piedmont and delta blues. Bob Wills' Country is swing with steel guitars instead of horn second. Hank Williams' honky tonk pulls a lot from electric blues. Big and Rich remind me of nothing more than arena-filling hair metal from the 80s. Examples galore. Nobody's going to say that "Whiskey River" is less country than "Great Speckled Bird" even as there's little in common musical between the two. The audience is the same, adjusting for time.

This is distinct, of course, from which industry it came from. 70s Laurel Canyon Singer-Songwriter is very Country, but it can't from another place and spoke to a different audience. Taylor Swift's audience is suburban teenage girls, and the machine that developed her added some Country identifiers which are decreasing, but it is a mistake to say there ever was an overriding allegiance to the fundamentals of country in her music, in style or in subject. Which, of course, is more than okay. If removing what little twang there was in TS allows more people to let her music into their hearts, to allow something that moves them into their personal genre, so be it.

Here's a question for all LTL people: I open the door and we use the 3-D printer (when functional) and the soldering iron, talk about projects and such, and then go home. When warm, there's often a discussion right outside the door that lasts well after the lights are off and the door is locked. And, fewer and fewer people show up. What should we be doing to get new members and retain the interest of the old ones? What should we be changing?

I think I've asked this question before at the meetings, but really, the people who show up every week are not the people I need to ask. It's the people who don't show up anymore who I'd like suggestions from

Strikes me that those who have a monetary interest in MySQL would respond "if you want this, go to Oracle" and those who have a development interest in MySQL would respond "if you want this, go to MariaDB". Although, honestly, I don't know if either Oracle or Maria allow this.

But MySQL is increasingly reminding me of a dead mall.

When it starts a print, it tweets "Dunno if this is going to work, but in haiku form."

When it finishes a print, it tweets a picture of the final project.

Considering an event loop. When tweeted at or DM'd, something like "hey what's up", it tweets a picture of the current state.

Granted, we have to replace every atom of the printer before we can really start playing with that, but once that's done, we'd have to look into how to schedule this thing. We can't really get data about the current state of the print -- +Chuck Schwarz, tell me if I'm wrong -- but certainly we can say "certainly I'll tweet a shot".
