velosol··on DOJ unveils proposed Section 230 legislation
Further there are often laws that basically state "here's some general guide, executive agency X will figure out the specifics and publish that in the Fed Register as regulations."
velosol··on Wikipedia is getting a new look
In addition to underpowered hardware there's underpowered connections (e.g. bad satellite connections and rural cellular) where things like being able to turn off images in a browser can come in handy.

While wikipedia might not be the typical site there, there is something to be said that a site that deals in information (like a generator's manufacturers page) should at least have a low-bandwidth option so you can access the textual information you need without pulling in a presentation layer that isn't critical.

velosol··on We Don’t Like Our Underground House
For electrics - Rex Cauldwell's "Wiring a House" is written in an accessible manner that shouldn't send you to Google too often. A copy of the NEC helps if you want to really understand everything (or being willing to dig through contractor forums to understand oddball situations) but is overkill for most. The book is mostly about thinking about how to wire a house than prescriptive "this is how it must be done."

I've worked with lots of electricians over the years and the majority of the things in that book reflect the best practices I've seen. Things that don't go out of style like making choices that are respectful of the next person who will work on something. The thing that does go out of style is the NEC it is based on as the latest edition is from 2014 so some specifics may start to be incorrect but by and large it is still applicable.

velosol··on You might as well be a great copy editor
I agree but have found that I'm better at copyediting my own copy the further I am from it. If I wrote something in the last week I might as well be a spellchecker. If I wrote something last month I will catch more things but not as much as if it were someone else's writing. A year or more and I start to ask "Who on earth wrote this like this?!" :) .

I was a fan of that until I experienced that they don't actually test the code. I've had it break in entertaining ways, most recently getting a new monitor from Dell and trying to enter a phone number (on Firefox on Android, both current & Preview) went like this for the number 123-555-1212, typed without dashes:

Enter number, result is: 125-535-2112 .

On the plus side it was predictable and I was able to eventually enter the number something like 2153552121 and have it appear on page as 123-555-1212. When I encountered this a second time a few days later (reordering due to DOA) I discovered pasting the entire number in allowed the 'automatic' nature to add dashes correctly.

The correct answer to me is to strip out non-numbers and then verify the number is a valid phone number (which should be easier than programmatically determining names or dates).

Thunderbolt & Firewire before it. DMA to external devices is powerful but the feature also means you expose a bus that wasn't originally conceived to be read by malicious agents.

I wasn't aware of Answers.com; that's a great counter-example! I knew of a few of the others before this comment and I've viewed them as providing some amount of service or support for the price paid so yes they are selling GPL they didn't write, but they're selling something else (their time) along with it.

There's certainly an argument that selling support for software you didn't write (or didn't write in large part) is 'bad'. I also believe that if you are selling the (free/gratis, GPL) software without support you're not going to be in business long.

And all good points on the differences between CC & GPL, my only point was that selling compiled CC-BY-SA binaries provided security-through-obscurity level protection from someone reselling your product (when paired with trademark protection).

Thank you for all the things to think about!

velosol··on Using human brain tissue in lab, researchers show herpes link to Alzheimer’s
Thank you for the reply - I last looked into it for someone before the UCLA article came out and their doctor wasn't convinced by the French study but also wasn't completely against it. The person opted to not get the vaccine at that time. More and more it seems like the potential benefit is worth any side effects.
velosol··on Using human brain tissue in lab, researchers show herpes link to Alzheimer’s
Have you intentionally exposed yourself to your previous triggers (assuming you had them)?

How long has it been since you had the zoster vaccine?

Were you of an on-label age for the zoster vaccine at receipt or was it off-label usage? Put another way did you receive Varivax or Zostavax dosing and were you in the on-label group (1-50 for Varivax and 50+ for Zostavax)?

The data isn't great but there's a fair bit of anecdata as you report and in your link that suggests there might be some protection against HSV from the VZV vaccines, possibly based on genetics or age of recipients.

Also your link was broken for me but the below might work.

velosol··on FCC must reveal IP addresses and user-agent headers of net neutrality commenters
When you make a comment you are acknowledging that you are entering information to form part of the public record. I've not examined the specific FCC form but I would almost guarantee it clearly explains that your comment and likely metadata around it are protected in some ways by the Privacy Act of 1974 and explicitly not protected in other ways.

These logs could form the basis of a legal record generated by the executive branch of the government and even if they weren't they are likely subject to a legal hold as a result of on-going legal action.

Records in the government sense are very important to form an open trail of policy decisions and overall function of government. Deleting them accidentally can get you a firm slap on the wrist while deleting them intentionally can put you in legal trouble (and worse if you're doing it to cover-up wrongdoing).

The National Archives (NARA) holds on to all the various records generated by the functioning of the federal government for various time periods based on the content of the records. As to payment - costs are incurred in part by the generating agencies and then the taxpayers funding NARA.

Further reading: Privacy Act of 1974, [1], FCC's Comment Filing System System of Records in the Federal Register [2], Paperwork Reduction Act of 1980 (more towards only collecting necessary info), and FCC's Website Notices [3].

velosol··on British Museum makes 1.9M images available for free
I've always thought that a bit unlikely - if someone is going through the trouble to resell they take on business costs, probably some support or maintenance costs, and a desire to profit (otherwise they'd just post the GPL'ed portion publicly). There's also no guarantee the reseller has access to any updated upstream code (especially in the situation that undercutting results in the originator stopping production). Legal? Definitely. Profitable? Maybe, sometimes.

As I understand GPL it has a provision to provide source code such that it may be modified by a recipient of source or compiled code. I can't find anything similar in CC-BY-SA [1] other than a grant that the recipient of compiled code may reverse engineer that code if they desire so long as anything that person adapts is also shared under a compatible license.

While they could sell them for less they generally cannot sell as your product (name, logo, etc) is your copyright or trademark that you do not license when you license the code GPL.
velosol··on Keys.pub – Manage cryptographic keys and user identities
It's not a fun format to work in but ASN.1 is aimed at that and there's also protocol buffers, Avro, and messagePack, among others.
velosol··on Heat Pump Water Heaters
That's actually one of the general issues with heatpumps - because they aren't literally lighting something on fire (or using resistive heating which just lights money on fire) they have smaller temperature deltas when designed properly as you mention. This leads to things like oversized air conditioners in hot places because people will cycle the AC creating a high peak demand and if it isn't 'blowing cold' they think it isn't working.

Heat pumps (assuming they can vary their output, which most new ones can) work much better to keep a constant temperature whether hot or cold and actually create a really nice indoor environment if a) designed or sized correctly and 2) have good thermostat placement. There's plenty of software, standards, and guides out there to hit both of those and then you just have to educate the users to set a temperature and then forget about it other than monthly filter cleaning. This is hard coming from 100% or 0% duty cycle systems like most fossil-fuel heat and old-style air conditioners so some think heat pumps are 'wimpy' and don't work. Placement is also part of that - you shouldn't be sitting in the output of the unit (which tend to be lower velocity than forced hot air etc) because the unit should be placed so it can cool the entire space.

velosol··on Heat Pump Water Heaters
There are thermal battery suppliers out there (a quick search turned up Sunamp, one I hadn't heard of before) that can be part of that kind of system. Geothermal heat exchangers as floatrock mentioned are probably the cheapest general version that use the ground as a thermal battery but don't typically have interlinked systems - and they're much more than a typical air-cooled system.

The show This Old House showed an interesting system a few years ago at [1] that used liquid loop HVAC components and thermal batteries as a tech demonstrator. There's also systems in newer high rises that have linked loops such that the hot side of the building (sun-facing) can pre-heat the heat pumps of the cold-side (shaded) portion of the building. These rely on advanced systems that don't tend to be deployed in homes (utilizing newer building management systems and newer HVAC like variable refrigerant flow to get the best efficiency).

Ultimately, things like this are expensive and uncommon so require per-site design that very few can justify because the payoff period is pretty long as you have the one-off cost of the thermal battery and often higher maintenance costs because you need someone who understands the system.

Teams has an option for PSTN conferencing so if that's the only reason holding on to WebEx, it might be cheaper to add the PSTN option to Teams and ditch WebEx.

velosol··on First trans-Atlantic contact made on 432 MHz
1. I don't think you can quantify the two in equal units such that they can be compared - they both played a part.

2. Probably not or at least not significantly. Ducting occurs frequently and Saharan dust is blown out to sea every year. Note that 'for the first time on this band [at this distance]' is more accurate.

velosol··on First trans-Atlantic contact made on 432 MHz
The general field of signal processing - in particular to pulling data out of noise there are error-correcting codes, algorithms like Viterbi and putting them together let's you pull off pulling data out of noise, really signal from interference. There's an entry for FT8 on wikipedia that I haven't digested but it has some other starting points.

As to the physics there's also the fact that the phenomenon that creates a good transmission line between participants is in flux and you have to get your data through while the transmission line passes enough signal that the receiver can decode it.

Are the tests used in [1] (real-time RT-PCR) the same?

The false negative reported several times from the same patient is interesting, but may be more due to testing source (upper respiratory fluid vs. sputum or lower respiratory sources or blood).

velosol··on Ten-Minute Coronavirus Test for $1
This is good advice generally, especially for severe infections like COVID-19 but there's little evidence _specific_ to COVID-19 and a contraindication with NSAIDs.

The Snopes [1] article covers the general gist although there is an early report around that the minister likely read and passed on in the form of a tweet.

Research is changing constantly right now so evidence may or may not show NSAIDs contraindicated with greater risk than other infections.

Out of curiosity, why not have another user account on the computer? Windows is pretty simple to move between user accounts as is Linux and, although I haven't use macOS recently enough to comment, it was pretty easy the last time I did.

I'm sure our use cases are different but I'd like to understand yours better.
