On January 28, 2011, I launched this site to move beyond occasional tweets about technology, and to save things for future reference.

Dozens of times a year I’ll wonder which exact motherboard was in a system I built, or what vendor I regretted seeing sink into the ground like a big ol’ glowing gopher, and a quick glance on this site cleared things up for me more often than not.

Once in a while, I find something to post that makes a difference for someone else, whether it’s technical, soft topics, or even travel related (over on rsts11travel, which came four years ago this month).

As always, I have a draft folder full of content waiting to be drafted into service. Some new projects have come up, and some old ones have warranted a refresh, so as I get some stuff sorted out at home, I’ll get some posts out in the open for your enjoyment and education.

If you have suggestions or ideas, or even hardware you’d like to have evaluated, reach out through the comments here or our contact page and I’ll see what I can do.

And if this blog has helped you over the years, feel free to send me a virtual coffee at https://ko-fi.com/robnovak (the $3 suggested donation actually covers two Nespresso pods and then some, so it’s like buying us both a coffee, but I’ll drink yours for you).

Some longer anniversary posts from the past:

I didn’t think I’d be able to say this so soon… (He’s baaack at Tech Field Day!)

As many of my readers know by now, my time at Cisco came to an end last month. When I decided to leave Disney and come to Cisco 6 1/2 years ago, there were two main things I knew I would miss about being in the “real world” — Disney cast member discounts, and being a Tech Field Day delegate.

Well, there’s no change on the Disney discount front, but this week I’ll be back as a TFD delegate for Tech Field Day 22 the latter half of this week.

Riding in the limo at SFD5 in 2014 – four of the five people pictured will be at TFD22 this week with me

How did you get to this point?

In May 2014, I posted a two part post on storage vendors (“These 3 hot new trends” part 1 and part 2) from Storage Field Day 5, my last full event as a delegate. A month later, I moved to San Francisco for most of a week thanks to TFD sponsors, to participate in my second Cisco Live event and to interview for a position with Cisco.

I was offered the job the day I got home from the event, and a little under a month later I got badged at Building 9 and began the 6+ year adventure in mega-vendor sales engineering. But as a vendor, I wasn’t terribly welcome among the Tech Field Day delegations, although I was still invited to the parties, and managed to qualify for the roundtable at SNIA’s Storage Developer Conference in 2017. I did continue my participation with Interop over the years, leaving my Cisco ears (instead of my Disney ears) at home, and even attending a Cisco briefing during one of the events, in the former Playboy Club at the Palms in Las Vegas.

What is Tech Field Day? Do I need a ham radio?

If you’re new to Tech Field Day, the idea is pretty much the same as it’s been for over ten years, even if the participation venue has moved from conference rooms to Zoom. Stephen Foskett, founder of Tech Field Day and Gestalt IT, brings together independent analysts, practitioners, geeks, and javelin catchers to meet with companies producing something in the tech sphere.

From the huge established names (like Dell, HPE, Cisco) to companies just coming out of stealth and talking to the public for the first time, you get to see companies facing unstaged questions in realtime, discussing the product or service, the decisions behind them, and how people who might actually use the product or service see it rather than how the company’s marketing and PR team want it to be seen.

And unlike most press conferences and analyst events, anyone on the planet (pretty much) can tune in, watch and learn, and pose their own questions through social media to be answered. There’s no registration required, no event fees, and if you missed a company you can go back and watch within a couple of days.

Pro-tip: If, like me, you’re on the tech job market, Tech Field Day’s archives can be a great resource for learning about companies you might be interested in working for. Just go to the main page and search for a company name. Not everyone is in there, but you can get a good feel for the companies that are, from what they do and how they’ve evolved over the years to how well they understand their product and the market they’re competing in.

So what’s different for you this time?

Tech Field Day 9 in Austin, Texas (June 2013)

After five full delegate events in person, and seven roundtable/TFD Extra events (details), I’ll be back as a different kind of delegate, for obvious reasons. TFD22 looks to be the largest event yet, with twenty-five delegates. No, really, 25 delegates. The nine presenting companies will be split up into early and late shfits to accommodate delegates from around the world, and since none of us are traveling to an in-person location, we can focus on presentations in our own time zones… and some of us will be hopping onto the other shift’s events as well.

The early shift, for my European and Eastern colleagues, will feature Commvault, Veeam, VMware, Quantum, and Red Hat. Their sessions run from 5-10am Pacific, and while I’d love to see them live, I’m not sure 5am is a time I believe in just yet.

You’ll find me in the late shift (11am-3pm Pacific), meeting with MemVerge, Riverbed (who I last visited here in Sunnyvale for SFD2), Illumio, and oddly enough, Cisco. I only see three names among the other 24 who I’ve shared TFD events with, but about half of them are in my online circles and I’m looking forward to meeting the others.

If you’d like to watch along with us, check out the TFD page for livestreams on several platforms starting Wednesday morning, December 9th. You can click on this garishly-large TFD logo to get there if you like. And if you miss the sessions you wanted to watch, they’ll be posted on the same link within a couple of days for you to watch at no cost.

Feel free to follow along on Twitter and ask your questions – tag with the hashtag #TFD22 and the delegates will try to relay your questions to the presenters.

My three unfair advantages in the COVID-19 era

Posted on by
Reply

A lot of people have had to make a lot of adjustments to life in the pandemic era, from work to home life to eating and shopping.

I’ve had three serious advantages–some might even say unfair advantages–that made my transition smoother than most. Probably the most disruptive element of the shelter-in-place and travel restrictions for me would be the extra people in the house all day, and that’s still a bit unsettling at times.

But let’s take a look at the advantages, and see if they might help you as well.

1. I’ve worked from home for the past six and a half years.

This one is hard to do retroactively, of course, but in terms of remote access, working without coworkers face-to-face, and making my own coffee every morning (several times, most days), I was training for the pandemic since I started working for Cisco in 2014.

Before the pandemic, I did have opportunities to get out and see my colleagues in person, whether for our sales kickoff in Las Vegas or conferences or team gatherings at company headquarters. Those have mostly dried up, although I did see a partner engineer briefly a couple of months ago when dropping off a couple of pieces of hardware for him.

I have had to adjust the home environment for the new “coworkers,” including a high school student and a non profit program director who were doing their daily grind in the house, the latter in front of my “daily grind” machine farm… never quite got around to setting up a coffeemaker in my home office, but I did get a second beverage fridge set up.

I have to admit that I hadn’t really prepared for the letdown of virtual conferences, but I wasn’t entirely surprised. On the upside, almost all of the content from the half dozen conferences I’ve “attended” has been made available more promptly afterward, so I can go back and review a lot of it rather easily.

2. I’ve spent weeks in Las Vegas over the past decade

You might be surprised by this advantage, but it definitely prepared me for some of the personal hygiene issues that we’ve been asked to address to slow the spread and reduce risk of contracting the virus.

After the first time or two that I got sick after a trip to Las Vegas, I learned to wash my hands frequently and to never, ever touch my eyes or face unless I had just washed my hands or had a wipe to use.

As a melting pot of bacteria and viruses and just ordinary grime from all over the world, Las Vegas is an easy place to pick up something you didn’t want, whether from handrails, escalators, elevator buttons, door handles, and the like. Browsing through electronics and thrift stores could sometimes leave “weird stuff” on my fingers, but nothing like the handrails at Planet Hollywood or elevator buttons at Mandalay Bay.

So getting in the habit of washing my hands regularly (not just after going to the bathroom, although that’s one a lot of dotcom workers never quite figured out), and keeping my hands away from my eyes (one of the two easiest places to get things introduced to your bloodstream), helped reduce the risk of getting something in Vegas, or in conference facilities elsewhere, or partner offices, or just around town.

I’ve overused subscription services for several years

Note: This section contains affilliate and referral links. You can obviously search for the sites yourself if you don’t want to toss me a few bucks here or there, but I appreciate those of you who do.

There are usually cases of toilet paper and/or paper towels, and plenty of antibacterial wipes and sprays, on a shelf in the garage or in the front closet, thanks to the Amazon Subscribe and Save program. Some brands and products have disappeared from the program over the past few months, and others have popped up (including the “pick 8 scrabble tiles to name your brand” sort of companies), but between these offerings and the occasional sale at Target, we were pretty well positioned on paper and cleaning products from the start. Yes, there was one $1/roll toilet paper purchase, but

I also have to admit to keeping my breakfast/snack drawer under my desk stocked through this program as well (Clif nut butter filled bars, Kind bars, Belvita breakfast biscuits).

This program does mean that at the beginning of every month, I have to review what I’ve used as usual, and what I don’t need for another month or two. And I would recommend comparing the pricing and varieties to what you can get locally, as sometimes you’ll find a better deal at a grocery store or big box store. But as a backup in case you forgot to buy napkins or paper towels or car fluids or even underwear, it’s worth looking into the option.

Check your credit cards for Amazon promotions, or look into one of the Amazon branded credit cards. For example, Discover Card has 5% back on Amazon purchases for the fourth quarter of 2020, for example, and Chase Freedom has them sometimes as well. (These are refer-a-friend links, and I will likely get a modest reward if you sign up for a new card through them.)

And if you’re more inclined toward boutique cleaning and hygiene supplies, you may want to look into Grove Collaborative. They had toilet paper when other online sellers were running low, and they carry Mrs Meyer’s method, Seventh Generation, and their own house brands of various products for bath, kitchen, and general household cleaning.

They can be pricey compared to mass market stores and brands, but if you’re looking for uncommon products and environmental friendliness in your purchases, it’s worth a look. We’ve bought two large boxes of their supplies, and will probably look at restocking for the holidays, but we still mix these products with the more common brands.

Where do we go from here?

I’m hoping that things continue to stabilize, and I’m already looking forward to a careful visit to Las Vegas this winter, and a car club weekend run in the late spring. I’ve added disposable masks and hand sanitizer gel to my car club trunk bag, but we’ll see what else becomes relevant as normal comes back closer to normal.

Revisiting Fry’s Electronics a year later

Posted on by
4

A little over a year ago, I wrote about the decline of Fry’s Electronics. I have to admit that I didn’t expect the pandemic and its related impact, but I didn’t expect Fry’s to continue on its steady coasting path.

I figured they would either rebound over the holidays or fade into history. As you may recall from the updates, they did not make any visible advances over the holidays, dropping the ball on Black Friday/Cyber Monday, but they didn’t disappear altogether.

This weekend I went back to the Sunnyvale Fry’s store, the one I’ve probably been to more than any other. I think this was the first time at least since February, if not before, that I’ve been to a Fry’s store.

I was a bit surprised.

Fry’s Sunnyvale parking lot, November 1, 2020

The shopping cart corrals were empty, but the parking lot had a couple dozen cars. When I walked in, there were a few people around, and I saw a couple of employees. One was working in the repair shop, and two were behind the register counters where one register was open. There was no register line.

Motherboard display, Fry’s Sunnyvale, November 1, 2020

As I made my way to the flash memory section looking for some MicroSDXC cards for my new Jetson Nano development kit, I was surprised to find the motherboard display disassembled altogether. Last time I was there, they had one motherboard in stock, with five pieces on the shelves that used to be here. This time, I saw absolutely no motherboards.

They did have a modest assortment of SD/MicroSD cards, some even priced on the shelf, and a couple of adapters for reading them on PCs. I believe there was one brand name card, a 64GB Samsung EVO of some sort, and a lot of fringe brands (including the Hyundai cards which actually work pretty well).

Computer component station

The stations where you would normally go to talk to a sales associate or get an invoice and/or price match were marked for social distancing, and abandoned. I saw this in components, computers/printers/monitors, and the television section. I will admit I’d feel guilty price-matching at this point, but it seems like it would be a challenge to get help if you needed it. The only employees I saw were re-shelving things near what used to be the computer section.

I didn’t get photos of a lot of the store. There was one desktop and a couple of semi-offbrand laptops in the computer section (on the former Apple islands), and the remainder of the computer display was limited to a couple of monitors and a few open box PC cases (moved from the far end of the store apparently). Car Electronics has been pretty much decimated, along with the bedding and exercise gear displays.

3D printer filament display

A couple of positive surprises were visible though. There was a healthy display of printer filament for your 3D printing needs (pictured above). I’ve bought almost all of my filament from Central Computer, but I would consider trying some of the colors from eSUN here before ordering online.

I also found the “maker” / Raspberry Pi accessory section, also in the aisles where electronic components used to be (and some still are). There was an abundant selection of cheap 120 and 240 gigabyte SSDs, for prices similar to what I’ve paid for used drives on eBay, so I may go back for some of those when my next Rabbit door comes in. It looked like memory and CPUs were in short supply, but there were reasonable (think Best Buy level) stocks of USB flash drives and SD cards.

The one thing Fry’s seems to have outdone themselves on is personal protective equipment (PPE). The front aisle adjacent to the checkout line was half PPE (several varieties of hand sanitizer, including gallon jugs, as well as masks and protective clothing). So if I run out of what I’ve picked up at Marshalls or TJ Maxx, I could probably stock up here.

Where do we go from here?

It’s hard to tell whether Fry’s will improve their rather stagnant effort to convert to consignment models with their vendors. A few stores (including Palo Alto and Anaheim, as well as one in Georgia) have closed, and it looks like the others haven’t improved much in the past year (based on my observation and some social media posts friends have shared with me from other stores).

At this point, for some limited categories, they are a viable option. With the stores being rearranged, you may have trouble finding a “Fry’s Advisor” or the new location for the products you’re looking for, but they have improved on a couple of categories.

I’ll keep you posted on what I hear – watch for updates here if they happen.

See last year’s Fry’s post here — History of Silicon Valley Indeed; is Fry’s Electronics Dying?

And pour one out for Billy, the Fry’s Electronics social media guy. He takes a lot of flak from people wanting to rag on the store, but stays coherent and professional through it all.

Rabbit Reorganization: Building low power clusters from a rabb.it door

Posted on by

As you saw in my 3D Printing series, after years of pondering a 3D printer, I was finally inspired to buy one when a pile of clusters came up on eBay from the defunct rabb.it video streaming service.

In this series, I’ll take you through turning a rabbit door into some useful computing resources. You can do something similar even after the clusters are sold out; a lot of people have probably bought the clusters and ended up not using them, or you can adjust the plans here to other models.

The first thing I will put out there is that these are not latest-and-greatest state-of-the-art computers. If you’re looking for a production environment or DDR4 high density memory, keep looking. But if you want an inexpensive modular cluster that’s only about 5 years out of date, there’s hope for you in here.

The original cluster

eBay seller “tryc2” has sold several hundred of these “door clusters” from rabb.it, a now-defunct video streaming service that closed up shop in mid-2019. As of this writing, they still have a couple dozen available. I call it a “door cluster” as the 42 inch by 17 inch metal plate resembles a door, and gives you an idea of the ease of manipulating and fitting the environment into your home/homelab as it is delivered.

The cluster bundle will set you back US$300, plus tax where applicable. While they’re available, you can get one at this link and I’ll get a couple of dollars in commission toward my next purchase.

The cluster includes 10 Intel NUC quad-core boards (mine were NUC5PPYB quad-core Pentium; my friend Stephen Foskett got some that were newer NUC6CAYB Celeron boards which took more RAM). These boards feature one DDR3L SODIMM slot (max of 8GB), one SATA port with a non-standard power connector (more on this later), Gigabit Ethernet, HDMI out with a headless adapter (to fool the computer into activating the GPU despite no monitor being connected), four USB ports, and a tiny m.2 slot originally intended for wireless adapters.

In the center of the “door” are five NVIDIA Jetson TK1 boards. These were NVIDIA’s first low-end foray into GPU development, sold to let individuals try out machine learning and GPU computing. There are much newer units, including the Jetson Nano (whose 2GB version is coming this month), if you really want modern AI and GPU testing gear, but these are reasonably capable machines that will run Ubuntu 14 or 16 quite readily. You get 2GB of RAM and a 32GB onboard eMMC module, plus a SATA port and an SD slot as well as gigabit Ethernet.

The infrastructure for each cluster includes a quality Meanwell power supply, a distribution board assembly I haven’t unpacked yet, two automotive-style fuse blocks with power cords going to the 15 computers, and a 16 port Netgear unmanaged Gigabit Ethernet switch. With some modifications, you can run this entire cluster off one power cord and one network cord.

What’s missing?

So there is a catch to a $300 15-node cluster. The Jetson nodes are component complete, meaning they have RAM and storage. However, the NUCs are barebones, and you’ll need some form of storage and some RAM.

For the Jetson nodes, you’ll need an older Ubuntu machine and the NVIDIA Jetpack software loader. For the installation host, Ubuntu 14.04 is supported, 16.x should work, and later versions are at your own risk. You’ll also need an Ethernet connection to a network shared with your Ubuntu machine, as well as a MicroUSB connection between your Ubuntu host and the Jetson, to load the official software bundle.

For the NUCs, you’re looking at needing to add a SODIMM and some form of storage to each. I bought a bunch of 8GB SODIMMs on eBay ($28.50 each) to max out the boards. For storage, I tried USB flash drives and 16GB SD cards and had OS issues with both, so I bought the MicroSATACables NUC internal harness for each board, along with Toshiba Q Pro 128GB SATA III SSDs (these are sold out, but there’s a Samsung SM841N currently available in bulk for the same price, about $20 each).

If you do get a cluster bundle with the two-memory-slot NUC boards, you have two options beyond the above. The easy and documented option is to look for 4GB SODIMMs instead of 8GB; you may save a buck or two, or if you’re like me, you may have a box of 4GB SODIMMs from various upgrades and not have to buy anything. The other option is to update your BIOS on the NUC and try out 2x 8GB. For some uses, 16GB will be worth the cost (vSphere or other virtualization clusters). I’d suggest going with a known quantity to update the BIOS to the latest version, and then trying 2x 8GB.

One other thing you may need is a pack of spare fuses. I know they do their job, as I blew a few of them while plugging and unplugging the boards. But you may wish to have a few extras around. They’re the standard 3 amp “mini blade” fuse that can be found at auto parts stores (although my local shops tended to have one card of them, if that, on the shelf). You can also buy a 10 pack for $6.25 (Bussmann brand) , a 25 pack for about the same price (Baomain brand) or a 100 pack (Kodobo brand) for about $9.

Choose your own adventure

There are two paths to take once you have your gear collected and connected.

  1. How do we lay out the gear?
  2. What do we do with it?

I’ll look at my journey on both paths in upcoming episodes of this series. Spoiler: I’ve 3d-printed stacking plates for both the NUCs and the Jetsons, and am still working on how to mount the remaining pieces so I can e-waste the door piece. And as I write part 1, I still haven’t figured out what to do with the clusters.

Where do we go from here?

If you’ve bought one of these clusters (or more than one), feel free to chime in on the comment section and let me know what you’ve done with it. And stay tuned to this post (or @rsts11 on Twitter or Facebook) for updates on the next installments.
