The Raspberry Pi 4 is a great incremental improvement of the RPi platform. It handles Ubuntu 20.10 64-bit decently.
I mainly use R for my data-science practice, and I wanted to try R on this RPi. As of November 29, 2020 there are no pre-built packages I can use to install R. At a minimum, no r-base-core package is available for the arm64 platform at the R package repository. You have to compile R yourself.
Here’s a way to do it. Andrés Castro Socolichprovided most of this, and I edited a couple of steps. Open a terminal window (ctrl-alt-T) and run the below lines, one at a time. Be advised: I have an RPi 4 with 8 GB RAM, and it used almost half the RAM at one point. Also, the first make command will take a very long time.
Dallas ISD’s Student Transportation Services (STS) is a clown show.
This school year starts my eighth year of enduring poor busing service. This year started with a comedy of failures, and STS slashed its bus-stop count.
STS had the whole summer to get everything right. They also had a full week of route-running under their belt: the first grade of each school was in session a week before all other grades.
As is DISD STS’s custom, school-year start is a series of failures:
On days 1 and 2, the bus driver declined to check student temperatures, even denying that it’s her responsibility. (See above video. It may not be fully intelligible in the video due to other noise, but the driver both says 1. she has no temperature sensor and 2. it is someone else’s responsibility to check student temperatures.)
On day 1, five kids on the route were abandoned at their school. DISD sent a too-small bus. It had less capacity than the number of students who entered the bus that morning at just one stop!
On day 2, despite a promise made to me late on day 1 by a director at the Lawnview Service Center, DISD continued sending a too-small bus. Bus was overloaded per one-student-per-seat rules, and had wrong number on placard.
It does this with the 10-person outdoor gathering-size limit.
Scout units could resume by moving everything outdoors. That would be safe—outdoor Coronavirus transmission is rare, especially if everyone masks when distancing is not possible.
While the EO excepts “youth camps” from the limit, that is widely interpreted to apply only to professionally staffed youth camps. That excludes the vast majority of Scout camping events, like troops going on a weekend campout.
I urge you to do two things:
First, permit Scout units to re-engage in unit camping. Only one safety-measure is needed: mask when distancing is not possible.
Second, exempt state parks from the gathering limit, at least for Scout units.
I joined the pack in June 2010, when my older son aged in as a Tiger (that was before the Lion program was introduced). This is a promo photo I used in the letter to Alec’s friends’ parents:
I was Den Leader of the prior Den 3 for five years. It was a great run! The parents were so supportive!
This is from our last meeting, in February 2015:
I tell new den leaders that the hardest meeting they will ever have is their last meeting. You can’t tell, but I was crying like a baby right before that photo was taken!
How could it get any better? Hold my beer…
I went on to become Pack 862’s Cubmaster two weeks later (Feb. 22, 2015), about three months before Ethan became age-eligible for Cub Scouts.
We got off to a rough start, where the spring family campout had to be canceled due to weather concerns (in retrospect, that may have been a mistake!), we weren’t able to break past a 20% membership decline (versus when I joined), and our popcorn fundraiser’s sales tanked.
But things turned around, and man, what a great ride it has been. Thanks to the incredible support of YOU, the leaders, and the parents, in the past five years, Pack 862 has:
Grown 82%, from an already large pack, to become the largest pack in the 24 county region!
Became the primary Cub Scout pack for two new schools (Reilly and Reinhardt) and is also the home for kids from many other schools.
Grown the pack committee to become a model committee. If BSA wanted to produce a “how to” video for Cub Scout packs, all they have to do is put cameras in this pack’s committee meetings!
Opened the program to girls.
Created a culture of continual improvement and of welcoming feedback.
Increased popcorn sales by 213%.
Set a new record for pinewood derby entries.
…and much more!
It was such a privilege to be a part of this. I have never, ever experienced an organization so mission-focused and united as this pack.
When prepping for large pack activities, I felt deep burnout several times. Despite that, I always was back in my happy place when the event was happening and, when it was done, I was eagerly anticipating the next event.
Now it’s all done. It is so hard to leave that behind.
This may make me sound sheltered, but leaving Pack 862 is emotionally the most difficult thing I have ever experienced. I dreaded this for two years. When I broke down at one of the summer 2019 committee meetings, you were seeing that raw emotion surface. I somehow held it together during the Blue and Gold Banquet (except during the slide show, but you probably didn’t see that). Plus I’ve had waves of emotion ever since then. It’s hard!
But the change needs to happen. I really meant what I said at the banquet, that Cubmasters are like underwear, so they need to be changed occasionally. The longer I was Cubmaster, I could see the pack’s identity getting entangled with my identity. I’ve seen cases where other packs flopped due to them getting overly identified with a leader who moved on. Even at Winter Camp this year (that program is for older, Scouts BSA members), someone that I don’t even know mentioned Pack 862 as that huge pack (good!) that is Aren Cambre’s pack (bad!). On top of that, given that Ethan graduated to the next program, it was time to move on.
Now above, you see me writing a lot about the pack as an entity. You may remember me emphasizing that the den leaders are the most important position in the pack. And that exposes a conflict: I regret not investing enough time in you, the den leaders, and your dens. I am sorry for that. There were times when dens and den leaders needed an extra boost, and I didn’t always step up like I think I should have.
You are very lucky to have the current “key three” leaders:
Christopher Calle, the pack’s new Cubmaster, has the spirit of adventure in his core. He started Wood Badge, the highest form of local adult leader training in Scouting, just two months after joining! As a successful small business owner, he has a keen sense for how to operate an organization the size of Pack 862. He and I have been working on transition and handoff for a year. You may not have realized this, but I’ve been mostly phoning it in for a few months because Chris has been mostly running the show! Please be sure to support him in his new role! (Be sure to hassle him when he ad libs through an event error! 😁) Additionally, Christopher has shown dedication to where I didn’t do as hot: he ran a den for half a year that needed help (it wasn’t his own kid’s den!), and he is actively thinking through ways to improve den leader initial training in the fall.
Melody Stevens, Committee Chair, has organized the committee to become something I have never seen in the history of this pack. Dating before my time, the Cubmaster and Committee Chair have both shouldered far too much of the duties that the committee should be doing. That is not a great dynamic. Melody has done amazing work to turn this around. We have the best staffed committee ever, we have enthusiastic, committed committee members in key roles, and it’s working well!
Alesia Pearson, Chartered Organization Representative (COR), is our official representative to Central Lutheran Church. You don’t see her much, but let me be very clear about something: this pack is VERY lucky to have such a supportive COR and chartered organization! Alesia fully supported Pack 862’s move to include girls. Except for occasional scheduling conflicts, Central Lutheran has never said no to building use. That is a huge deal! I’ve seen other situations where Scout units struggle with chartered organizations that were disinterested or unsupportive. Pack 862 is VERY lucky to have such a supportive, community-minded organization that has its back.
Out of respect for Christopher, I need to keep some distance from the pack. Growing up in a Methodist minister’s family, I saw how it’s important to let the new leader take charge without the prior leader’s presence clouding things. I am still working with Chris and Melody behind the scenes on transition matters. I’m also sharing my crazy thoughts with them, which they are ignoring if they are smart.
Also, what I identified above are things important to me. This is your pack, so you will need to identify what is important to you! They may be different than my priorities. I can’t way to see how this pack grows and evolves with your new goals.
My own next steps in Scouting are continuing to build up Venturing Crew 863 (for ages 14-20) and support Ethan’s journey in Troop 861. I’ll still be around.
In conclusion, thanks again for a great ten years. I am not gonna Rickroll you because I do need to say goodbye. But I’m never gonna give you up: Pack 862 will always have a strong place in my heart.
You have great leadership, and I am excited to see Pack 862’s next steps!
P.S., Want some beeeeeeeanz? [Note from Aren: This is an inside joke. Ask me to serve you beans to see what this refers to.]
I have monitored Dallas County Schools’s and DISD Student Transportation Systems’s failures to provide effective transportation services, and I was an activist in the DCS shut-down effort. I have been interviewed by the Dallas Morning News (link) and NBC 5 (link).
Regrettably, dissolving DCS has not improved bus service. DISD STS continues to provide shoddy service to students and parents.
Instead of fixing its problems, STS now wants to make things worse by regurgitating its failed hub proposal from last year. A school’s SBDM exposed this by sharing that DISD STS wants to “streamline” service. This simply means they will reduce service quality by having fewer stops. In other words, STS wants to make their poor service even worse!
It appears that DISD STS is using its on-time record to say it’s doing a good job. While an important figure, two things to understand: 1. Even if it’s on-time, DISD STS is failing in equally important areas. They are at the bottom of this post. 2. It is easy to manipulate the on-time figure. In the NBC video linked above, DCS is cited as having a 98% on-time record, but it is exposed as fudging that figure. Due to persistently poor performance, DISD STS has not earned my trust, so I want to understand more about DISD’s on-time performance before I can accept it.
