How do I test cast iron cookware for lead

So I found a griddle that was in pretty bad shape seasoning wise so I stripped it and noticed a small shiny area which worried me about lead. I ordered some lead tests that stated they were for metal (no specifics) and after doing the tests it came back positive. But this got me wondering if iron reacts with sodium rhodizonate, the main ingredient in these lead tests, to give false positives and load and behold it does. I confirmed this with another cast iron cookware that I know 100% never touched lead. So my question is how the hell do I test this? Everyone keeps recommending the same sodium rhodizonate lead test swabs just with different brand names.

Tldr: After stripping a griddle and finding a shiny spot, I tested it for lead and it came back positive, leading to concerns about the reaction between iron and sodium rhodizonate. The question is how to accurately test for lead contamination in the griddle without potential false positives from the test method recommended by others?

Edit: wanted to add some more info. I did experiment with the test themselves to see how reliable they were and they passed it so I don't suspect its the test themselves but the chemical reaction between iron and the sodium rhodizonate

To start off: I was explaining to my friend that I don't have a grounding point in my house (plumbing is PVC, outlets are gcfi protected only, not allowed to drive a grounding rod into the ground, etc...) and that I've just been handling sensitive electronics with just luck and preparation (humidity, moisturizer, no synthetic clothing, etc...) all this time. He told me to just wire myself to a good, multimeter tested, grounding point in a car and that will discharge any built-up static electricity. I'm not smart enough to argue with him on this subject but that doesnt seem the safest. Would that work or should I just keep doing my method? My understanding is that chassis grounding is essentially replacing wires with the frame so the outcome would just be connecting myself to the negative terminal of a car battery.

Tldr: I'm explaining my lack of a grounding point at home for sensitive electronics and is advised by my friend to wire myself to a grounded point in a car to discharge built-up static electricity. However, I'm uncertain about the safety of this suggestion and questions whether my current method of handling electronics with precautions is sufficient.

Edit: lmao people are really getting hung up on the no grounded outlet part. Umm my best explanation I guess is that its an older house that had 2 prong outlets and was "updated" with gfci protected outlets afterwards think the breakers as well. My understanding is that its up to code but I'm not an electrician. As for the plumbing I'm sure there's still copper somewhere but the majority has been updated to pvc over the years. Again it's not my house I don't want to go biting the hand that feeds me. Thank you though, haha

Edit #2: thank you all so much for the helpful advice, I really appreciate all of you!

Saw a video of a youtuber that got his account overtaken which has 2fa enabled (not sure which method but I'm thinking sms). He says he didn't get phished, downloaded anything and his session cookies weren't stolen and I believe him. The only clue is that he received a sms otp from google but was invalid when he inputted it which let's me to believe he relied on SMS for 2fa in the first place. My theory is he reused passwords and his number was overtaken but I'm not sure if that's the case since he did receive the google otp so that leaves out the common phone rep social engineering methods of porting out and fowarding. What else could it be? My paranoia is kinda acting up

Tldr: A YouTuber's account was hacked despite having 2FA. While unsure of the exact method, potential factors include relying on SMS OTP and the possibility of password reuse. No session cookies were stolen, nothing downloaded and no links clicked

Edit for timestamp: its kinda difficult since he jumps around a lot but he begins to talk about it around the 2min 30sec mark and stops at around the 6min mark

Basically just the title. With DVDs getting tossed to the wind it made me wonder when will blu-rays go? I'm gonna miss bloopers and extra scenes

Edit: A bit confused but the general consensus is that in some areas BRs have already began to be phased out while in others they're just trucking along perfectly fine. It'll be that way until they stop being profitable to the studios who make them. Is that correct? I don't think the 8k argument is valid imo since that's really niche currently.

This always puzzled me. Why don't humans act much more aggressive or crazed like its often depicted with animals. Afaik there's 2 types of rabies, "dumb" and "furious" so my question is more towards the 2nd type. For example, we never hear of rabies causing a human to accidentally bite another human so why is that?

Just curious what are the top 3 podcasts you listened to this year on whatever platform. Antennapod released a feature that summarized your year and well the amount of hours kinda surprised me in a good way, haha.

Edit: Mine were

• The let's read podcast
• Therapy gecko
• How To Survive

Hey, I've been using collabora to edit/open some spreadsheets on android but it's honestly becoming a bit of a pain for me, freezing and blanking some cells being the big ones, and so I'm looking for an alternative. I tried excel without network access and it works but I do have to clear storage everytime to bypass the "signin prompt" that shows up randomly when opening a spreadsheet which disables editing, so I would like to avoid that too if it's possible.

I've been using veracrypt for the past 4 years to create container files in everything from thumb drives to external hard drives. After upgrading one of my backup drives, I decided that I will switch to a different filesystem altogether going on, from ntfs to ext4, since I havent really used windows in those 4 years. With the reasoning behind using veracrypt and ntfs in the first place being for compatibility, should I switch to LUKS? Veracrypt is dramatically more feature rich but I dont really take advantage of those. I just encrypt my drives in case of burglars and other unwanted eyes. I do already have a disaster plan in place so I would have to do a total overhaul of things, but I'm not sure if this is a wise decision. My gut says no but what do you think? What would I gain?

Edit: shouldve added that these drives are for warm storage for my weekly manual backups of files.

Edit 2: the general opinion is to use a tool that supports encryption but I dont really feel comfortable with that but do appreciate it. It's just I've been manually updating my backup drives for a while now and like how simple my routine is. Think my decision is to just stick with veracrypt but format every future drive (including a new one I ordered) as ext4. My current drives wont be reformatted in order to reduce unnecessary wear on them. Thank you all for your help

Hiya, pretty much the title. I have a dozen tapes I want to backup before age takes its toll. My basic idea after watching some videos online is to buy a hardware based upscaler that can interface with my vcr then throw that signal to a video capture card and record on my computer. I'll go with name brands to avoid problems but is that really the best method? I want to avoid sending them to a service since it will cost more than just buying the hardware in the first place and I got time to kill.

In short I need a cheap external disc drive and dont want to cough up the 20$ and buy online so thrift store it is. I cant really come up with a way to test these usually usb powered drives besides somehow setting up a computer or asking the workers for help (doubt they will). Does anyone have an idea to narrow down if a drive is defective or should i just take a chance and hopefully the store has a return policy?

I seem to be generating excessive amounts of saliva to the point where I need a disposable cup to kinda drool it into every couple of minutes. This makes sleeping kinda hard and so I'm wondering is there a trick? I had to make a sort of makeshift bib out of a towel just to combat this last night and that allowed me to get a few hours but man was it uncomfortable. Any advice?

Edit: the excessive saliva finally went away last night. Appreciate all of your help

Hey so I'm new to the world of gpg/pgp. Using a test gpg key pair I created, the goal was to digitally sign a odf so I was wondering what do I backup so I could keep signing digitally using this key in case shit hits the fan and my computer no longer works? Using seahorse, I perfer it to the terminal, the options are to either export the public key or the secret key and I'm honestly confused should I do both or just the secret key? I did notice people also just take a copy of their .gnupg directory but I feel thats just to backup all of their keys including imported ones rather than a singular one. Any help is appreciated preferably as if you were talking to a 5 year old

The TLDR: Just created a gpg key pair now how do I back it up?
