The rising revolt against customer surveys
Click the headline above for the full article.
I too have stopped taking most surveys, because there's so many, and I often don't believe the data is being used to improve the service or product. And as I've said before: make those surveys short and easy; if you try to take advantage of me because you have my attention, you'll no longer have my attention.

How to make a portable battery-powered keyboard station
My son is a percussionist in his high school band, and this year the band's halftime show needed some keyboard work. He was asked to help out with that. But, the band director said, the whole setup would need to be very portable, and completely self-contained power-wise, because extension cords would not be possible in most of the places they play.
The below is what we came up with, with much starting advice from the band director. I'm documenting it here in case some other band needs something similar, or some street performer or busker can use some help with how to do this.
Here's what it looks like:
We initially spray-painted the hand truck black, but it turns out that doing that, over nice shiny new painted tubes, doesn't work very well, it tends to rub off on hands. So we ended up wrapping everything we could with black electrical tape.
The battery unit we used is a computer UPS (Uninterruptable Power Supply), for the following reasons:
The below is what we came up with, with much starting advice from the band director. I'm documenting it here in case some other band needs something similar, or some street performer or busker can use some help with how to do this.
Here's what it looks like:
It is essentially a hand truck with an amp strapped to it, and the thing above that is the battery unit. The keyboard rests on 4 magnets that are attached to two shelf brackets.
We started with a hand truck. This is one of the cheaper ones we could find, and it is definitely strong enough for all we're doing. It is a bit short, though, for a 6' person standing and playing, so if you are a taller person who will also be standing, you may want to find a slightly taller hand truck, or use some different way to mount the brackets/magnets up higher (which is difficult on this one because the handle bends backward at the bottom of the keyboard here).
We initially spray-painted the hand truck black, but it turns out that doing that, over nice shiny new painted tubes, doesn't work very well, it tends to rub off on hands. So we ended up wrapping everything we could with black electrical tape.
- self-contained: one box that contains the battery, the inverter, and the charging system.
- The UPS we chose (a CyberPower CP1000PFCLCD PFC Sinewave UPS) was chosen especially because it has pure sine wave output, which is important for more sensitive electronics (such as a synthesizer, and the other amp we have that has effects built in). Using these devices with a regular "stepped approximation" inverter can result in poor performance, lots of noise on the audio output, things heating up, and reduction in lifespan of the device, if not outright breakage.
- UPSes have intelligent charging systems: just leave them plugged in when not out in the field, and they'll stay perfectly topped up, and will never overcharge.
- This UPS has a discharge gauge and other displays that help you know how it's doing.
- It is light and small, I still can't believe how much play time we get out of it. (The amp you use and how loud you play it will have everything to do with how long it lasts, so I can't even begin to guess what success you'll have, but we are using here a 50-watt Crate bass amp, turned up mighty far, and at band camp it was used several times a day without issue... at home we tested it about 50% loud, playing demo drum tracks from the synth, and it played continuously for 40 minutes until we couldn't take any more dancing, and it was still at about 80%.)
- This use is definitely means the warranty doesn't apply, so please don't expect (or try to get) any help from that direction if it fails.
- It ships in a fault state (for shipping safety), and must be plugged in before it can be turned on. This is important to know because if it ever faults out in the field, you'll need to plug it in somewhere in order to turn it back on.
- It did fault out a few times when we first started using it, and we found out that it really doesn't like to be laid on its side. Once we turned it upright as you see here, all was well and it had no further problems. No idea why, it doesn't have any moving parts except maybe a relay. We did put feet on it, as you'll see in other pictures, to keep the vents clear on the then-bottom. Hmmm.
- In its default state it beeps every x seconds when it's on battery power... but using the software that comes with it loaded on a computer one time lets you disable that. It does still beep when it's turned on and off, but that's not too bad. You can also disable the beep from the onboard control panel each time you start it up if you wish.
- It will charge when it's plugged in whether it's on or off, so it will spend most of its life off and plugged in in the high school band equipment room.
The Korg Microstation uses just teeny little sips of power compared to the amp.
The straps we used to hold everything together were possibly the hardest part of the whole thing to get right. The system was supposed to be all black, so that immediately limited things. I ended up using:
- lashing straps to keep the amp on the hand truck
- ladderlock straps to keep the UPS on the hand truck
But I don't like them: in this installation (possible because of the small lengths involved) they don't stay tight (especially as this whole thing rattles over bumpy fields and into equipment trailers and over door thresholds, etc.), and I can't even get them as tight as I want in the first place. In one of the first versions of this system we used a ratcheting tie-down, and it worked great, they can get very snug, and stay that way, but it was not black. (I only just now found that one, and may get a couple of those... that one is especially nice because it doesn't have hooks, it's an "endless loop" tie-down, which is better for this short-length use. I will use two for the amp, and one for the UPS.)
Yes, the keyboard is a bit crooked, but you probably would't have noticed it if I hadn't said anything. :-) It's because either the handle is uneven, or the top cross-support (behind the UPS) is crooked, and that's what I used as the guide for where the shelf brackets were installed.
The coil cord in the instrument cord that connects the keyboard to the amp. All the other cords are behind the foam. The foam is there to keep all the cords in, and it seems to work very well even on bumpy ground (and when in motion, the hand truck is tilted back and everything really wants to fall out and throw itself under the wheels). In this image you can also see that I cut the extra length off of the straps, and used a flame to seal the ends of the straps (as per instructions). Then a simple knot was applied to keep the ends from dangling.
The keyboard is held onto the hand truck by two shelf brackets that are screwed to the upright tubes of the hand truck (a screw each in the top and bottom of each side). This was easily done with a standard drill, although drilling holes into 1" diameter tube can be a bit of fun. Then the magnets were bolted to the horizontal section of the brackets. The small ones at the back used the existing holes in the brackets; I had to drill hols for the magnets closest to the hand truck, but it is thin metal and easily done. I used bolts with lock nuts to keep them from shaking loose.
We started with 16# magnets in all four spots, but we bumped up the ones closest to the handle to 25# to provide better grip (one of the things my son must do is pull this on to and off of the field while he's also wearing his quints, so having the keyboard stay on for sure while he pulls it one-handed is important.
Keyboard leaning against amp with back facing this way |
To give the magnets something to hold on to, we taped big washers to the bottom of the keyboard. I used Gorilla Tape, which is very strong and the right color.The bigger washers for the bigger magnets on the back side of the keyboard needed some extra tape on the left there... if I need to redo anything I'll move the magnets away from the handles a little bit more so the washer fits on the bottom without the tape crawling up the back. Magnets are very much affected by distance... even just putting a layer of tape between the magnets and the washers decreased their strength quite a bit. For example: the 25# magnets held the washers so strongly, when directly applied, that you can't pull them off, you have to slide them until enough of them are sticking out that you can leverage them off. With the tape holding the washers in place, the keyboard can be removed from the mount (with all four magnets in play) easily enough. You've probably noticed this yourself: holding one sheet of paper to the fridge is easy for a given magnet, but add a few more sheets, and gravity wins the battle.
That little strip of tape on the top (back) of the keyboard is to let me son know where to put down the keyboard: when you have that tape right at the upright tube of the hand truck, the washers are directly over the magnets, for maximum strength.
We found that the whole thing was initially a little wobbly when played, so we screwed a piece of wood (painted black) on the very front bottom of the amp, and it props things up enough that it's stable now.

How to remove the rubberized coating on your mouse
I have a Microsoft Wireless 2000 keyboard/mouse combo, and while I like it a lot, I find that the rubberized coating on the mouse tends to wear away and/or get sticky feeling within a few months of heavy use.
I initially tried using Armor-All on it, and that helped a bit but not for long. So after reading about the issue elsewhere, I decided to remove the coating and just get down to the plain smooth plastic.
I used a Magic Eraser, lightly dampened at the corner with some 91% isopropyl alcohol I keep around for electronics cleaning. I had initially tried just a paper towel, but it was slow going; the Magic Eraser really moved things along.
Note: rubbing alcohol, especially in the stronger percentages, can harm wood finishes and other surfaces. I did all of my work on a dark hand towel folded so there were 4 layers of it between my work and the table.
Melamine foam, which is what Magic Erasers and other similar items are made of, is pretty cool stuff, and is deceptively spongy, but shouldn't be used on skin or other sensitive surfaces.

Surge Dread - Uber
"The problem that these people have with surge pricing is rooted in the certainty that one day Uber, which is undercharging for its services in a drastically unsustainable way in order to fuel outrageous levels of growth, is going to win. And, when it does, after eliminating taxis and other car services—and maybe some forms of public transit in some cities!—it will extract a terrible toll for the convenience, probably when people need it most. Not because Uber is evil or attempting to punish its users, but just because it’s good business; Uber is, after all, the most publicly pitiless company of our time. (This is the same basic reason that people are afraid of—and investors still love—Amazon: Prices are unbelievably low right now, but one day, when everybody else is out of business, it will finally screw everyone in a monumental way.)"

Wi-fi adapters that work with Linux
I rehab old computers that have XP/Vista on them and could still be useful. For some reason the Dell wireless cards found in many laptops do not work well with Linux, so I've been on the lookout for a USB wi-fi adapter that works well. The TP-Link TL-WN722N works flawlessly, installs without any comment in Zorin, Mint, etc.
That one sticks out a fair bit, so I use a short USB extension cable and tape it to the back of the laptop's lid.
I also discovered that the TP-LINK TL-WN725N works just as well, and because its nano size will work better for laptops because it doesn't stick out so far. Not only did it install without an issue, but from two rooms away from the 802.11G router it got maximum download speeds as tested by http://speedof.me .

Fixing a sticky-sided Microsoft mouse
I like Microsoft mice. My current one is part of the Microsoft Wireless Desktop 2000 which is an inexpensive wireless mouse and keyboard. However, it is getting sticky, as in tacky, on the sides, where I hold it. I had thought it was just dirty, but in looking around on the internet I see that many others have this issue (also with products from other manufacturers), and that it's really the breakdown of the rubberized paint used on the devices.
I had a Lenovo keyboard at work that had this rubber surface on the wrist rest, and it was just becoming uncomfortable to use because it felt icky. I tried cleaning it with strong (91%) rubbing alcohol, but that made it way worse, so much so that I threw the keyboard away.
There are many pieces of advice out there to sand such surfaces, or use Goo-Gone, or melamine sponges etc. to remove the rubberized surface. Then I read, in a couple of places, the recommendation to use Armor All (the car stuff) on the surfaces. I decided to do that because it was non-destructive: I sprayed some Armor All on a microfiber cloth and polished the mouse with it, twice, and it has helped a lot. If it doesn't last long I'll probably try the Goo-Gone to strip away the rubber coating, take it down to plain smooth plastic.

If it doesn't last long I'll probably try the Goo-Gone to strip away the rubber coating, take it down to plain smooth plastic.

bad design of web form
I just had to check if a couple of Lenovo Thinkpad batteries qualified for replacement under the recent recall. I couldn't use the automatic software scan, so had to go to https://lenovobattery2014.orderz.com/ and enter the info.
Issues:
Issues:
- after entering the long (and hard to read) battery serial number, 22 characters of some squished-down sans-serif font where the C was almost identical to these old eyes as an O, I also had to enter the machine type and serial number. Why, because the battery might work okay in a different machine? Even if they did need the machine info, wouldn't the serial number suffice (because it would indicate the machine type as well)?
- I kept getting messages that the serial number and product number were invalid. Finally figure it out after looking stupid in front of a coworker: even though the label on the computer and the help page for the form both have dashes in the values (such as a machine type of AB-1234), the form won't accept that data unless you leave out the dash. !!! The easiest thing, requiring maybe 2 lines of code, would be to strip dashes out of the input; but the *least* they could have done was provide instructions to leave those out.
- After successfully removing the dashes myself, I get: "Invalid Barcode: A valid barcode has 22 characters, begins with ‘11s’. The letters "I", "O", and "Q" are invalid. Please check the battery label and try again.". A properly-designed serial/product number would not even have confusable numbers in the first place. And indeed, the problem was an O that should be an 0, and that zero was in the middle of letters.
I wonder how many people had trouble with, or couldn't even use this form, because of these issues.

You're Worrying About GMOs For the Wrong Reasons
You're Worrying About GMOs For the Wrong Reasons: "Scientists have demonstrated that genetically modified organisms have no measurable negative impacts on human health. Indeed, they may hold the key to feeding a world impacted by climate change. But does this mean GMOs are completely without risk? Nope. Here are some good reasons to be concerned."

Use Google Scholar to search for answers from published science
The internet is a vast and wonderful place, and although everyone has the freedom to say whatever they want there, this is also something that should make us cautious. For example: I remember hearing that sourdough bread is better for diabetics than regular bread or even 100% whole wheat bread, because the fermentation process of "proofing" the bread changes the starches so that they take longer to be digested, resulting in less of a spike to blood sugar (which diabetics are forever trying to manage).
I found lots of info on the topic, alongside claims that it also helps with the gut biome (because the probiotics survive the baking process? I think not), so I was hoping to find a trustworthy, rigorously tested affirmation.
Then I remembered Google Scholar, a subset of the Google search engine that only provides results from published scientific/scholarly studies, books, etc. The resulting search did indeed validate what I had heard.

- specific help for effective searches
- you can't always get to the full article of an item, but in many cases the abstract presented provides a nice overview of the information that will be enough
- can sometimes be hard to read, because many studies are written by scientists for scientists
A note on sourdough bread: it is difficult to find true sourdough bread, the sourdough bread sold in most stores and even bakeries is instead just soured bread: regular bread with acids and other flavoring agents added to give the taste of a sourdough without the other benefits. The only place I have found locally that produces real sourdough bread is The Old World Bakery in Bay City. They use a starter that they've proudly kept going for over 9 years. Update: Panera Bread also make a real sourdough bread , a nice regular-sized loaf, and you can order it online and choose your slicing width and just go pick it up at the local store.

The secret eyes watching you shop
The secret eyes watching you shop: "Most Americans don't even know that data brokers exist, let alone that they collect and trade a staggering amount of our personal data. Brokers operate invisibly, buying and selling data about us without interacting directly with us."

Audio/video web content manifesto
"Brothers and sisters, we deserve better than this, and those whom we write for
deserve better. This is not what we built the web for! For the first
time in human history, you can have anything you write read by millions
of people, whether within days or within hours, and all it takes is
talent, imagination and the discipline to put up something worth
reading. There are no obstacles anymore - so why must we create new
ones?" Link

use multiple cell phones via single (multi-handset) home phone system
This phone system [link] lets you use cell phones with a multi-handset cordless home phone system. As described by someone I work with:
"At our house we dropped the home phone because already had 2 different cells in the house.
So you come home, put
your cell phone near the base station for charging. It ties in via
bluetooth. If a phone call comes in, all the cordless phones ring.
And it is a distinctive ring to differentiate one cell from another. So
dad’s ringtone in the house is different than the ringtone for mom.
Placing a phone call is easy too, when you pick up a cordless, it will go out
on cell #1. If you hit Flash 2, then it goes out on cell #2 and so on."
"At our house we dropped the home phone because already had 2 different cells in the house.
But, for convenience,
got a combo cordless phone/answering machine with cell phone integration.
For example, Panasonic makes a base station with 3, 4, or 5 cordless handsets –
that gets a cordless phone in each major room…. Plus an answering
machine. The Panasonic also integrates up to 3 cell phones with
Bluetooth.
