That was a lot of fun.Although, I'm not sure heels are the appropriate footwear for operating studio cameras. I wonder if they just grabbed her from another part of the orgianisation and said "Hey, management said we need a woman to be in this video, can you come here and just wear this headset and push this camera around a bit for us?".

content: I'm interested in diving into these areas out of personal interest as well as broadening my knowledge base, particularly in the area of electromagnetics. I have degrees in mathematics and CS (BSc CS, BSc Mathematics, MSc CS), but have always been interested in electronics. These days I find myself very much working at the junctions between software and hardware, and I'd like to have a better grasp of EE fundamentals. Thanks to going through a rigorous undergrad program in math and in CS (in which I also took multiple graduate classes), I have a pretty good level of mathematical maturity, but realize that I do need some review of vector analysis and differential equations most likely as it's been a bit of timePersonally, I believe a graduate degree is merely a license to learn, so I take that to heart to learn new things as much as possible.What's some good online resources for this area? I was thinking MIT open courseware might have some stuff, but was wondering if anyone has any particular favorites. I have a solid EE library that I inherited, so I have access to a lot of classic texts as well.

content: I don't have any recommendations for classes, but I highly recommendGriffithsas a basic E&M textbook. As an undergrad I found the vector calculus challenging but extremely rewarding. Griffiths explains concepts clearly (and uses consistent notation). Given your education background I doubt you'll have an issue with it.I think it's a fairly widely used textbook for intro E&M classes so you'll probably run into it elsewhere. It's really only E&M theory, so if you want practical applications (e.g. antenna design) or concepts beyond E&M (like circuit analysis) you would have to look elsewhere. I have references for those subjects as well, but none that I'm quite as fond of as Griffiths.As for actual courses, I havethis listbookmarked (not mine), but can't speak to the quality of any of them.

For weddings I normally just give some cash, bit of a cold heartless gift but it ends up quite useful when you have expensive weddings.If you are too high on the Aspergers scale to realize what the advert is about, the idea is to minimize waste. Done by gifting based on what people want rather than just gifting random presents that may end up in the trash. They are also supporting and encouraging sustainable businesses, but I think the message slightly off when you attach a huge bank brand to it.It would be way better to see a credit union or a profit share type company for the sustainable business rather than seeing a bank doing the marketing. I had a look at the products and most of it is consumer shit anyway.

I am spent out already, and calling Amazon for hours at a time is like entering "The Matrix" with no exit. I thought I may as well ASK at least, no obligation or guilt implied here, just someone asking, so don't take my request as grabbing or begging, because that's not the spirit in which I am askingIf not, no worries, and thanks for reading anyway. Thanks.Never mind, I've sorted it - the lower part of the plastic probe housing where the cable enters, slides back slightly (as if there's some form of well-attached internal connector between two internal parts). I pushed the strain relief part hard into the main probe, and the switch tightens right up ans begins sliding and clicking again. Clearly this is not a discrete switch component, but some moulded in leaf/actuator.

content: For what it’s worth, Amazon’s only solution, ever, is to replace the entire product. Like many retailers, they do not stock spare service parts, their system is not set up for that. (Even if an individual part is something they sell, their inventory just isn’t set up for that. And I’m sure their agreements with manufacturers are such as to only perform whole-product returns. If amazon shipped you a probe, it’d come out of their pocket. If they return the whole scope, it’s the manufacturer’s problem to deal with.)Just know that a) they pay for the return, and b) if doing without the item would cause a problem, just ask them to do an advance exchange. It’s never been a problem any time I’ve asked for it. They simply ship another and give you a certain time (a month IIRC) to return the original, after which they would bill you for it if you don’t return it.

YMMV what supply voltage and work coil you need.The power supply in the video is probably delivering a few kW, but the efficiency will also be poor with that one-turn coil. A soldering iron at 60W (and better efficiency) would still be able to do that joint, given perhaps a minute or two of heating time (and if you didn't mind having a blob of solder on the outside). Probably 200-600W would be adequate for a reasonable production rate, and with a tighter fitting coil.Tim

Make sure they are even difficult to recycle, so that recyclers hate you too. Make sure you use a cheapest crap battery pack, well sealed inside so there's no way of replacing it. Use the cheapest switches and controls, so they can wear out soon.etc... Not surprising to find this stuff.

How hard is for Google to develop the controller in the same way? Same robustest to handling but at the same time easy to disassembly in case of needing a fixing.In the current place, is one more thing that will die, when the battery dies, when the contacts wear out, and it's throw into a landfill, since by trying to open it will damage it for sure, and be throw in the landfill anyway.

Not made for kids" because my videos are mostly reviews, electronics, teardowns, hacks and so on.However, I have a few videos on games (played mostly on Linux WINE) and I have occasionally reviewed or played with (or torn apart) toys. These are not made for "kids", as the discussion is too technical or usually has to do with installation tips. I flagged my entire channel as NOT MADE FOR KIDS, but what happens if a kid decides to watch one of my videos? I don't have any inappropriate content, everything is rated "G" and there is no bad language.I guess the easiest way to know my stuff is NOT made for kids is that my own kids don't want to watch my channel. They are completely BORED by it!!!!Can anyone explain more about what this COPPA stuff means? Is it safe to just say NO and that's it? Who is this COPPA stuff targeting and does that actually remove advertising or change advertising/monetization at all? How did this issue start and how are you supposed to decide what is "Made For Kids" exactly? Does a tutorial on Scratch Programming count? What about Arduino? What about if I do a video on hacking a remote control car?

Distributed platform for forum hosting - Page 1

content: Anybody knows any distributed forum platform software, or example of live forums like that, please?By distributed I mean some sort of peer to peer storage, where the forum database is stored distributed on the forum member's computers, and accessed without a centralized client/server architecture.Today's forums are driven by owners, and they need to make money to pay for the hosting, so we see ads or other commercial tactics. Another inconvenient with centralized forums is that the laws usually make the owner guilty for what users are talking/writing on the forum, which is very unfair to the owner.There are distributed chat systems, I think, but chat is not a good platform for storing and categorizing discussions. I think the forum is the best balance between invested time, community benefits and openness for anybody who want to comment or add info on a given subject.Any ideas about a distributed forum project?

Posts take up to a day to show up. But that's because it's trying to solve a much harder problem which is keeping posters truly anonymous.

Importing laser rangefinders into Australia? - Page 1

content: The 360 degree scanners are now super cheap, but Australian customs regularly seizes anything labelled as a 'laser', or if looks like a 'laser pointer' due to idiots using then to harass aircraft and people. Customs doesn't care if a laser is visible or IR, they all get treated the same.Sure, you can buy locally but then the cost is much higher.So does anyone have any first hand experience with importing any of the newer LIDAR systems? Do you simply get a letter saying that it has been seized?

With the proper permit, you can import all manner of things.Gettingthat permit, however, can be the fun bit.You have at least started by asking questions - and, unfortunately, I don't have any answers ... but keep asking.Just make sure you have done all the groundworkbeforeordering your thingamajig.Here is the site which should have your answers:https://dfat.gov.au- but finding your way could be challenging.

Don't know about LIDAR, but there are plenty of rangefinders < 1 mW, which should be fine to import. If the power is higher, then by Australian law you need a licence to operate it anyway.Their enforcement isn't even particularly good, since plenty of people have been able to buy DPSS green lasers on eBay ... the ones that are marked as 5 mW or less but are actually more like 20 mW, and probably have non-functional IR filters.

If that happens then yes it is exactly as reported. Although probably we should also look in a different way and try to understand how Bolivia is nowardays.As a country Bolivia is a poor country, although Mr Morales changed the constitution to limit the presidency to two terms and brought a lot of people from poverty thanks to his reforms and economic policy. But at the same time he also ordered and commanded the courts and the electoral authority and was often ruthless with opponents. In his determination to remain in power he lost a referendum in 2016 to abolish presidential term limits (strange because before he abolished that, and now want it is back), but then got the constitutional court to say he could run for a third term and won last month in a dubious victory, specially when a outside audit confirmed irregularities that the opposition was saying they happen (similarities with a certain country on the east that have been in the news lately, with some changes...).That was basically what made the army revolt against him, and the coup that we say. There is a video from someone who explains perfectly well how things work in this kind of political environments.It may be look like a coup d'etat orcrestated by the CIA, but it looks a lot more like something was wrong in the country and people said enough! Although we can always use the Lithium deposits and refuse of a contract with a German Company that coincidentally provides a Big American Corporation that also have a factory in China and probably don't need all of this thing because anyway they win...
