tomswartz07··on DOT and FAA Finalize Rules for Small Unmanned Aircraft Systems
Technically, it's 400' from the tallest surrounding object.

So, yes; you can technically fly to 1400ft near a 1000ft building.

tomswartz07··on My open-source, do-it-yourself cellphone (2013)
Not much.

It uses GSM, which can be listened to by a RTL-SDR or any other software defined radio.

tomswartz07··on How and Why to Log Your Bash History
Could it be that you're accidentally adding/copying a space at the beginning of the command?

I know Linux BASH will ignore the command from history if that's the case, and I think that OSX is similar.

tomswartz07··on Type III Societies (Apparently) Do Not Exist
Somewhat tangentially related: a non-scientific discussion on what Type I, II, and III Societies are, and why they might not quite make it.

tomswartz07··on Do not talk about pricing
It's metric ton, as in one thousand kilograms.

That's to illustrate the difference between an imperial ton, which is 2000 lbs (or ~907kg).

tomswartz07··on OSBoxes – Virtual Machines for VirtualBox and VMware
Once you sink the time into setup, it really takes care of itself.

You could basically schedule/cron/whatever the job to build once a month/week/day on your machine and it will always dump the up-to-date virtual machine in the location you choose.

I should also point out that Packer is the program that they use to create Vagrant boxes.

tomswartz07··on 1M People Use Facebook Over Tor
Probably not a lot. I use it to bypass firewalls sometimes.

If it's worth that much money to you, how much of your time would you say?

The reason I ask is that Hashicorp's Packer[1] is awesome at doing things like that.

Personally, I have an automated Packer build that spins up Windows 8.1 and Windows 10, provisions it and installs all of the necessary software, and then preps it for Windows Deployment Services. I originally based the work off of packer-windows[2] but ended up re-rolling most of it again from scratch.

If you don't mind spending roughly a day or two figuring it out, then it's well worth it!

tomswartz07··on Ubuntu 16.04 (Xenial Xerus)
Just a side note, as well:

`apt-get` is depreciated, they've moved to just plain `apt`

`apt install foo`

tomswartz07··on If you're alive in 30 years you might be in 1000 years too
On a lighter note, I can imagine that the size of the ego which accompanies the type of person that lives to 9,000 years old would more than likely encourage someone to poison or strangle them.
tomswartz07··on NASA proposes new propulsion to cut Mars voyage to 3 days
I think you're having trouble grasping exactly how fast 200km/s actually is.
tomswartz07··on LinkedIn shares drop 40%, erasing $10B of company's value
> There's nothing to force LinkedIn to change the negative aspects of their service

Yeah there is: a $10 billion drop in their stock valuation.

tomswartz07··on Bad USB-C cable destroys laptop
It's not the standard that's bad, it's the actual wiring of it.

That's akin to saying:

The US power grid is a bad standard because I wired up my house wrong and it burned down.

tomswartz07··on Out of a Rare Super Bowl I Recording, a Clash with the N.F.L. Unspools
That's a humongously bad precident to set.

    You happened to record, using your cell phone, a major news story?

    Whoops, sorry. That video is no longer yours.
It's far better to fix the Copyright regs that have been so modified recently that is causing this. Thanks, Disney.
tomswartz07··on Microsoft reveals details of Windows 10 usage tracking
Here's a 100% serious question:

If you 'absolutely must' use Windows 10, would it be possible to firewall off every outbound port from this machine to prevent this sort of tracking? Or does it just use Port 80, piggybacking on the normal http traffic?

Has anyone done a comprehensive analysis of exactly how this info is being sent?

If they make the limit infinite, you'd end up being paid -1/12 of a cent.

tomswartz07··on A Cosmonaut on the Moon: Korlev’s N-1/L3 Plan
Personally, I absolutely love the design of the Soviet space vehicles.

Perhaps it's a result of the chronic underfunding of the program, but the utilitarian look for the LK3 lander is amazing.

tomswartz07··on New U.S. FAA rule requires drone owners to register by Feb 19
You're correct.

Having no power in a model airplane is definitely an issue.

My main point being, however, it's arguably far easier to manuver an airplane after motor failure than a drone/quadcopter.

tomswartz07··on New U.S. FAA rule requires drone owners to register by Feb 19
I wouldn't say 'absurd', I'd consider it very conservative, however.

I think 2.5 miles is plenty, but there could be legitimate reasons that full-size aircraft would be flying near 400 feet near an airport.

tomswartz07··on New U.S. FAA rule requires drone owners to register by Feb 19
Quadcopters ("drones", ugh) are unable to maintain their altitude if there is a power failure. If one or more of the motors fail, it falls like a brick.

Airplanes, however, are much different in that they could softly and easily glide back to earth after a motor fails.

tomswartz07··on New U.S. FAA rule requires drone owners to register by Feb 19
Only if you're flying rocks at over 328 feet in the air.
tomswartz07··on New U.S. FAA rule requires drone owners to register by Feb 19
A good number of idiots do fly 'only above [their] own property'. The issue is that they fly much higher than 400' above their property.
tomswartz07··on New U.S. FAA rule requires drone owners to register by Feb 19
The only requirement is the weight.

Yes, if your 'toy' is over the minimum weight, then it has to be registered.

However, there are a great number of inexpensive toy drones that are less than $100 and fall below the weight requirement. See the Cheerson CX-10: http://www.amazon.com/Bestpriceam-Cheerson-Cx-10-Quadcopter-...

If you want to avoid having to deal with the registration, then purchase a toy that doesn't have the ability to hurt someone.

The article does not link to the FAA's website.

Here's the link to the actual FAA page: https://www.faa.gov/uas/registration/

It appears that registration opens on 21 Dec, 2015. Further, if registration is done before January 20, 2016 the $5 registration fee will be refunded.

tomswartz07··on Ask HN: How do you track issues, todos, features?
This is a similar method to what I use as well.

I even wrote a Vim syntax plugin for the todo files: https://github.com/tomswartz07/vim-todo

tomswartz07··on Drone Maker DJI Adds Technology to Limit Where Its Machines Can Fly
Really it depends on the frame.

I have a $50 UDI U818A and (with the plastic frame) if I cut the power, it falls no faster than a leaf. It actually does the same 'wobble' and lands softly on the ground.

Larger multicopters, like the DJI ones in the article, are much heavier. About 5lbs or so. They fall fast and hard.

tomswartz07··on Drone Maker DJI Adds Technology to Limit Where Its Machines Can Fly
> Enough of an obstacle to block general population from doing their stupid things, while still allowing those who know what they're doing to exercise the full capabilities of the machine (taking the responsibility for eventual damage).

This is exactly it. I'm 1000% okay with this. I hope that the eventual DOT regulations are following this line of thought.
