velosol··on Eat, Drink and Be Wary: Ex-CIA Officer Reveals How Eateries Are Key to Spycraft
Gilman Louie says hi ;) .
velosol··on Data as a Property Right
Generally yes.

When someone says "I give up this freedom" it's often because they don't use it or it doesn't affect them. The problem is that what they are really saying is "I give up this freedom for myself and everyone else."

This is bad when you have a large group willing to give up a freedom they already don't use or care about that only affects a minority of people. The problem comes that a different, overlapping large group is willing to give up another freedom and now the minority affected by that loss was part of the first large group. It's easy for this to continue until everyone has lost a freedom they enjoyed because they signed up with some large group, often thinking they were 'right'.

TL;DR: The road to hell is paved with good intentions.

velosol··on Identifying a person through walls from video footage, using only WiFi
For those wondering the bottom line, it is interesting preliminary research on a small pool and I expect will be quite interesting as it progresses.

"The lab has tested their new technology on 1,488 WiFi-video pairs, drawn from a pool of eight people, and in three different behind-wall areas, and achieved an overall accuracy of 84% in correctly identifying the person behind the wall."

velosol··on Hackers Hit Twitter CEO Jack Dorsey in a ‘SIM Swap’
> "It doesn't leave much to choose from."

With Google anyway you're down to 2FA using an authentication app (possibly U2F but I haven't checked on that recently) and backup codes which should also protect you from traditional hacking.

I would think in addition we'd have to see the ability to book with a specific driver for a future ride for 'lead generation' to hold up.

velosol··on Attorney General Barr and Encryption
Perhaps OP was thinking of the criticisms around Dual-EC-DRBG?

velosol··on Attorney General Barr and Encryption
The 2A and crypto have been linked for a long time. The original crypto fight in the 90s was over exportable encryption (because it was listed along with munitions and other ITAR-restricted items).

One idea I saw floated around the time of the San Bernadino iPhone was arguing that encryption is protected by the second amendment as a means to not having to fight against backdoored encryption every few years. I don't have the case law familiarity with the 2A & encryption to say if it would go well but I did find it a fun idea.

Edit: I should add that this would be in addition to the clear 1A protection code and therefore encryption has.

velosol··on The floppy disk orphaned by Linux
> In a saner world, the 240 MB LS-240 would have been the last floppy.

Years ago I longed for an LS-120 but by the time I had the money a CD writer was the better deal. I occasionally look at eBay for LS-120s just for fun but I now have a new unicorn to search for and one that didn't even come out in the US - the LS-240. Thank you for a new bit of nostalgia!

velosol··on Mozilla debuts implementation of WebThings Gateway open-source router firmware
If you want to use HASS - there's a couple ways to go about it assuming you have an RPi. Either install Home Assistant and add snips.ai [1] or install snips and add HASS [2]. Looks like the Gateway can also do this [3].

velosol··on DuckDuckGo Expands Use of Apple Maps
>[...] Apple Maps was also demanding [I cross] a double yellow line where a left turn would've been illegal regardless of construction.

Do you perhaps mean a (solid) quad yellow line (aka a painted island)? It's legal to turn left across a double yellow into a driveway, private road, cross street etc in California (and every other state I've lived in long enough to look up the laws) per [1], specifically (d). It's _not_ legal to pass on a solid double yellow.

velosol··on Pentagon Ordered to Tell Congress If It Weaponized Ticks and Released Them
> Good example of people being unwilling to consider the facts.

Exactly! It's clear that the CIA found the frozen corpse before the expedition and extracted the bacteria to put into the ticks in the first place. [edit]/s[/edit]

I do somewhat appreciate the explanation the person used as it showed conviction versus moving the goalposts when confronted with new evidence; something that most nutty conspiracy theorists seem to do.

"Conspiracy enthusiast" perhaps?

velosol··on Florida DMV sells personal info to private companies, marketing firms
If you purchased a new home that public record of sale tends to be the source of a bunch of spam - often claiming to be important mortgage documents.

If you were renting it's possible your landlord or management company provides information on new residents for 'cost saving offers'.

velosol··on Hit by Big Loss, Bird Seeks $300M in New Funds
Typically Bird hunters [1] will go around with a pickup truck to gather a bunch of scooters to charge them. I've seen one pickup truck that appeared to be company owned rather than a bird hunter, but it seemed to have a decent system to secure the scooters and had many more than I'd ever seen a hunter get.

In any case, yes, drivers are responsible for securing loads, but in a lawsuit you go after the deepest pockets if you think you might be able to get payment. It would be an interesting argument that Bird is liable as the hunter is at least an independent contractor for Bird while picking up & transporting the scooters for charging.

[1]: Apparently this is the term for those who pull the scooters in and charge them and then redeploy them after the fact for a kickback from Bird.

velosol··on Why Three Prongs? (1996)
>By popping one circuit breaker at a time, I realized that these circuits coincided with breakers on the right side of the box.

I hope you got this checked out! There could be something wrong with the phase going to those breakers (if your box is of the kind that has phases split by side which I am unfamiliar with).

velosol··on Why Three Prongs? (1996)
Code makes the minimum calculation - as to how it originally came about I would guess a mix of empirical (committees working with various sized boxes as they work on NEC revisions) and then math to have a formula/table for the real world.

There are wire fill factors in the NEC - basically if you have a junction of a conductor of this size (gauge) then it must have this many cubic inches to go with it.

The simplest outlet (a receptacle) would have 2 conductors (hot and neutral) and those each require a certain number of cubic inches based on their size (12AWG and 14AWG being the most common). The cubic inches of a box are typically stamped on the box and the amount of conductors ('wire fill') must be below the box capacity. Ground doesn't (didn't?) count in the calculation as it shouldn't carry current normally so it's not a conductor.

If you've worked in a box at or near capacity (especially with a AFCI or GFCI/RCD) you will always put in a larger box given the chance.

velosol··on Minnesota Will Pay Residents to Grow Bee-Friendly Lawns
Zika [1], West Nile, Encephalitis, Dengue, Chikungunya have all shown up in at least Texas and Florida in the past few years [2]. While I agree reducing pooled water is the most important vector control action you can take, it seems likely that the US will not remain immune from arboviruses in the long term. Thankfully the vast majority of cases continue to be travel-related but there are small numbers of locally-acquired disease being reported since ~2013.

Which is to say in those areas at least you should most definitely wear long clothes, wear an approved repellent, and avoid sleeping in unprotected areas (rooms with open windows without screens, outdoors without netting, etc).

They also mentioned decay in the conversion process. I wonder if we have good data on the decay of the thermal-electric converters from missions like Voyager that have traveled through large portions of space or if they're being conservative?

velosol··on Temperatures in France cross 45°C threshold for first time since records began
Ah that makes more sense, thanks for helping me to understand the open windows viewpoint.

For me electricity is less expensive during the day (solar) and my house is well insulated so it takes fairly little to combat the heat gain during the day compared with letting the house heat soak through the day and then try to cool everything off in the evening. There's also often more humidity in summer so I'm trying to dehumidify at the same time and an adjusting AC (e.g. variable refrigerant flow or just a variable speed on the compressor) can run at lower consumption for longer to meet both needs at once.

velosol··on Temperatures in France cross 45°C threshold for first time since records began
You might like [1] and others in that vein. The passive house movement seems like a big deal in a few parts of the US (e.g. Northeast and some parts of the West coast). AC ends up being an important part of these homes as they're sealed so well that human-caused humidity (both direct and from showers, cooking etc) needs to be managed. You can get by with the equivalent of a small window unit for a 1500 square foot+ house though.

velosol··on Temperatures in France cross 45°C threshold for first time since records began
If the weather is such that you need AC or heat, why would you have the windows open? Add humidity to the mix and open windows become even more problematic.

An oversized AC is going to run more if you have your windows open when it's hot out although with humidity may actually work better as it'll run long enough to pull out some moisture (latent cooling).

If the issue is around fresh air your average pre-2000 house breathes plenty with closed windows and newer homes tend to have active ventilation (e.g. energy recovery ventilators).

I feel like I must be missing something or you live in a warm-temperate climate such that a heat pump heats faster than it cools (heat pumps go way down in heating efficiency as it gets cold out and most work very poorly when it's much below 0°F).

velosol··on US Navy's Railgun Now Undergoing Tests in New Mexico
>Concentrated water molecules visible as myst produced from hot water is steam.

Steam/water vapor/humidity is gas phase H2O and is transparent. Water droplets in air is often referred to as 'steam' or 'wet steam' but is liquid phase H2O suspended in air. If it mattered in context I assume it would be clearly stated as gas rather than liquid mist.

I doubt anyone would call the component of air that is 'humidity' by the word 'steam' but it seems it would be correct [1]. I am used to the term 'water vapor' for that gas phase H2O though.

velosol··on VESA Publishes DisplayPort 2.0 Video Standard
A couple years ago the other option was to dump the EDID of the connected monitor (while it was on of course) using Nvidia's display software and then set the EDID data using the same software (overriding the EDID which would apparently get cleared when the monitor sent its hotplug event). If you ever actually removed the monitor you'd have to go remove the EDID data.
