using yubikeys everywhere

Everybody is getting real excited about yubikeys recently, so I figured I should get excited, too. I have so far resisted two factor authorizing everything, but this seemed like another fun experiment. There’s a lot written about yubikeys and how you should use one, but nothing I’ve read answered a few of the specific questions I had.

RC40 card cipher

The Solitaire cipher is perhaps the best known encryption algorithm implemented with a deck of cards. Ignoring security, it has a few drawbacks. It’s pretty complicated. I can never quite remember the rules. Sure, with practice it’s possible to memorize, but ideally we want something easy to teach. It’s also pretty slow. Even with practice, the shuffling and cutting manipulations take time.

Samsung 960 EVO

Thought I was happy with my gaming PC, but there was a Steam sale, and suddenly 256GB just doesn’t stretch as far as it used to. Even purchasing only a few games per year, at 20GB or so each, that’s not much. Looking for a bit of future longevity, decided to make the switch from SATA to NVMe. Best drive on the market is probably the Samsung 960 PRO. Saved some money by going with the EVO line, which might be the best value.

OpenBSD on HP Stream 7

Recent events have rocked the mobile computing world to its core. OpenBSD retired the zaurus port, leaving users in desperate need of a new device. And not long before that, Microsoft released the Anniversary Update to Windows 10, but with free space requirements such that it’s nigh impossible to install on cheap 32GB eMMC equipped devices such as the HP Stream series, leaving users searching for a new lightweight operating system. With necessity as both mother and father, the scene is set for a truly epic pairing. OpenBSD on the HP Stream 7.

master lock speed dial

In addition to earbuds, I have a tendency to lose padlocks. As a result, I tend to go through more of them than I should. Note to locker designers: place the loop on the inside frame instead of on the outside of the door so that after I open the door, I have somewhere to hang the lock where I won’t forget it.

iphone 6s plus

Replaced my 5s with the new top of the line, 6s plus. Kind of an awkward name. I propose 7P and 7Ps for the next gen.

cheap earbuds

I consume earbuds at a fairly constant rate. They get lost, or washed, or fall apart. And then I need new ones. Unlike the collection of large headphones, or “cans” if you will, that I’ve accumulated over the course of ten years without casualty, earbuds are practically disposable. So I don’t like paying a lot of money for them. Nevertheless, I want a product with some level of quality.

as always bundling fixes is bad

I generally like my iPhone. I think it’s fairly secure, and Apple seems pretty motivated to keep it that way (even if they don’t have the purest intentions, caring perhaps more about jailbreaking than my safety). But the way the way they go about releasing security fixes is terrible.

catastrophic weather movie alert

Went to a movie this afternoon because it was raining. Because it was raining, the government issued a puddles of unusual depth alert, causing everybody’s phone to blow up mid movie, within the space of a few minutes. The weather catastrophe alert tone could have been a credible sound effect, coupled with some great positional surround sound, but all the lit up screens gave the trick away. Then it kept happening as the less important people were notified and started interrupting the movie. There’s always a few idiots who can’t turn their phone off, but the number of alerts received made it seem likely the alerts can override vibrate or even silent settings.

leave my bluetooth alone

Dammit, Apple, stop turning Bluetooth on after every iOS update. I turned it off for a reason.

if it ain’t mangled, don’t unmangle it

I have a song on my iPod, “Don’t Pull Your Love” (nonsensical fake video) by the grammatically ambiguous Hamilton, Joe Frank & Reynolds. Three dudes, four names (two first, two last). The software on my iPod Nano sees this and decides that at some point in the past some other software must have mangled up the artist name, and therefore the Nano must attempt to unmangle it. Result: appearing in both the artist directory and as the song artist I have Joe Frank & Reynolds Hamilton.

iPad Air review

Very early thoughts. Upgraded from the iPad 4 because that was too heavy. Almost went with the new iPad Mini, but reading magazines is a primary use case for me and I wanted something that more closely matched a real magazine in size. Also, the Mini isn’t shipping yet while the Air is sitting on my lap.

Brother HL-3170CDW printer review

I bought a new printer, the Brother HL-3170CDW (sometimes stylized HL3170CDW, as on Amazon). It’s a small office color laser, with all the doodads (wireless, ethernet, duplex, color). I didn’t really need it, the HL-2070N black and white printer I’ve had for several years now was working fine, but every once in a while I wondered if I’d find use for a color printer. Maybe I was making due with B&W because that’s all that was available, and having a color printer would unleash a creative blast of fancy greeting cards. I mulled it over for a few years, but then the price briefly hit $170 on Amazon. Done.

roku three

Got the new Roku 3. I had the very first original Roku (video player) from not long after it came out, then the upgraded XD model which honestly changed just about nothing. The model 3 is significantly improved.

m4 msata upgrade and OpenBSD

When my T430s arrived, OpenBSD didn’t yet support Sandy/Ivy Bridge graphics, so I stuck with Windows and OpenBSD in VMWare. Things change and now I want to run OpenBSD natively. I’m using TrueCrypt on the whole drive and trying to resize that while introducing another boot loader seemed a risky proposition, so I cheated a little by taking advantage of my laptop’s mSATA port and installed a 64GB Crucial m4 mSATA SSD, a trivial upgrade.
