I've never run into Bluetooth congestion problems on public transit or busy streets. BT has a lot of problems, this really isn't one of them. There are some BT devices that have poor antenna designs and underpowered transcievers,

The problem with Bluetooth is the stack is too complex. Too many application-specific profiles baked directly into the protocol, which in turn need to be dealt with by device manufacturers. Bluetooth basically handles everything from OSI La

It's just a fan + heater. It's not an air conditioner, nor is it marketed as such. I have one. It works pretty well. The air filter isn't as good as the massive Austin Air I use for my living room, but it's okay for a sm

They tell you you can have all the ice cream you want to eat, but neglect to mention that you'll be in too much pain and too nauseous to actually want to eat any. :P Believe me, all the ice cream in the world isn't worth that ex

The AMBE-3000 vocoder chip (used for pretty much all of the digital modes, including D-STAR and DMR) retails for about $50, before volume discount. Which is not a small mount of money, but isn't that bad given that most amateur radios

This system was designed by CBP, not Delta. So yes, it has access to the passport database. (See my other post here for details.)

Title is slightly misleading. This is only for for international departures, since it's tied to the passport + immigration databases. It's not for all Delta flights, since domestic flights are excluded. It's a CBP-operated

They each have their specialty. Evernote is better for filing documents / archiving things - whether those are PDFs, web pages, business cards, physical mail, etc. OneNote is better for free-form notetaking and editing. Each page feels

Verizon's billing practices aside, I'm surprised they're not using FirstNet (firstnet.gov / firstnet.com), since I thought the whole point of that project is to create a cellular network specifically for emergency servic

And on top of that, not everyone's phone will be charged, and not everyone will have cell service (if traveling internationally). The mobile apps are great when they work, but still need to be considered a convenience rather than a pri

Assuming you own your own home. If you live in an apartment complex or otherwise only have street parking, you likely don't have access to electricity. Or at the very least, would need to negotiate with the landlord to have a new outle

The thing I find really impressive is how weak the signals are. From that page, the downlink from New Horizons is currently 1.89kbps at -143.72 dBm (4.25 x 10-21 kW). That's 0.00000000000000000425 W. Not a lot of signal to work with th

The big benefit lead acid batteries have is that it's easy to find surplus SLA batteries from businesses, and even new cells aren't that expensive. That said, I've started seeing lithium batteries slowly catch on in amateur r

Both the solar cells and the batteries have a finite lifespan, and will eventually need to be replaced. Especially the batteries.

So much this. I've seen it happen time and time again. At least in Java, the reflection API serves as a "break glass" barrier to make sure folks understand they're doing something they shouldn't. Someone will still

But anti-cheat is largely obfuscation. Unless the host system is locked down (i.e. game consoles, systems with TPM-based verified boot), any state the game has access to is also going to be accessible to attackers. You can limit what stat

I didn't mean to imply that the concerns were unfounded. I know there are real, legitimate complaints with the touchbar. At the same time, I just wanted to point out that there are at least some developers who do prefer it, and that

I know it's trendy to hate on the touchbar... but for what it's worth, I personally find it more useful than the old function keys. Most mac apps don't use function keys as shortcuts, so the old keyboard ended up being used f

Out of curiosity, why do you need HDMI on a speaker? Especially considering that you don’t know how much latency the TV’s signal processing is introducing into the chain. I just run an optical cable from my TV to my Sonos soundbar. It’s sim
