With the exception of BGA a decent soldering iron is fine for SMD. I can solder a 144 pin 0.5mm QFP quicker than I can solder a through hole 40 pin DIP component.

But it's usually not those things that actually fail. Most of the random failures on electronics I've seen recently are:

* bad memory modules in computers (trivial to fix)
* bad capacitors (easy to fix)
* linear power regulators breaking their solder joints to the PCB due to heating/cooling (easy to fix)

Although we did have some LCD backlights that failed because as the capacitors started to fail, the power transistor in the DC-DC converter would also go (but it was extremely easy to spot due to the melted hole in the power transistor). We just replaced the LCD backlight DC-DC converter rather than doing any soldering.

It's very rare that some BGA chip is the thing that died in your gadget.

SMD components are not hard to replace (with the exception of BGA and their ilk). But the usual 0.5mm pitch QFP type stuff, to get the dead one off I use a hot air gun, and to put the new one on, flux, solder, normal soldering iron, solder braid and kapton tape are the tools I use.

Also I design most of my hobby electronics stuff to use SMD. Smaller PCB = lower price for the PCB, and a lot of the interesting chips only come in some SMD package.

What requires incredibly fancy machinery to fix?

While it takes some knowledge to fix a lot of things, fixing for example a faulty washing machine most of the time needs nothing more than basic hand tools and the ability to diagnose what is actually broken, then buying the replacement part.

There are some things that will require fancier stuff to fix, for instance replacing a chip in a BGA package on a circuit board requires specialist tools but a huge number of repairs don't require this kind of thing to be done.

Unfortunately ftp has far from died. There are so many other organizations I deal with that haven't been hit with the ssh/sftp clue stick and can't do anything other than ftp. Or worse still, ftps which is a firewall administrator's nightmare.

We even deal with one company who not only refuses to use sftp, but they refuse ftp in passive mode and want us to connect to an ftp server of theirs that only supports active mode. Their admin reckons ftp in passive mode is insecure and won't deal with sftp. Sigh. They are of course a Windows-only shop. Most of the companies who are stuck on ftp are Windows shops.

While I don't know whether "rebirth of VR" is hype or not I can say this.

Elite Dangerous through the Oculus Rift is mindblowing. VR that came before simply doesn't compare, it's like trying to compare a modern Lamborghini with a model T.

And this is yet another good example of why the scientific naming system was developed. English and most other "natural" languages tend to have a lot of illogical, confusing terminology like this. The strawberry tree is called that for the dumb reason that it bears fruit that superficially resemble the common strawberry. This satisfies people who only look at outer appearance, but tends to lead to incorrect reasoning when things that aren't closely related have similar names.

Similarly, we have a "highbush cranberry" bush in our back yard. It's a species of Viburnum that bears fruit the same size, shape and color as true cranberries. Both are about equally tart, and require some sugar to be made edible. But they're not close relatives, either, so the name can confuse people who don't understand the many problems with "plain English" names. They don't substitute directly in recipes, since the Viburnum "cranberry" contains one large seed, plus a lot of water. It works best if you squeeze the juice out and use it as a substitute for lemons or limes, with a flavor that's rather different from any citrus fruit.

Actually that model works very well. In many countries the internet provision is better and cheaper with more ISPs to choose from than in the US.

I live on a small island with 80000 inhabitants. We have an incumbent telecom company which owns the last mile, but they must sell that last mile wholesale. As a result, we have not one but four ISPs we can choose from at a decent price, and you can get at least 50Mbit/sec service pretty much everywhere despite the rural spread-out nature of our population.

We don't get the terrible Comcast-only situation many in the US have to deal with.

One of my favorite cases of such prohibitions was in a physics text for a physics course that I once took in college. One of the end-of-chapter exercises was of the form "Using the equations in this chapter, and tables X and Y at the end of the book, calculate the critical masses of the following isotopes ...". This has a reference to a footnote, which informed the reader that telling the answers to this question to an non-citizen was a felony under US federal law, punishable by N years in a federal prison. I've forgotten which textbook this was, unfortunately, or I'd include that info. I wonder if it's still in print?

There's an old joke in academic circles, to the effect that stealing from one source is called "plagiarism", but stealing from multiple sources is called "research".

There's a fair amount of precedent for this sort of idiocy. One of the funniest example, which got a bit of news coverage at the time, was back in the 1970s. The US Defense Department funded a study by a couple of academics, and paid them several hundred thousand dollars to study what could be learned from public sources about US military deployment. After the study's report was submitted, it took only about 2 days for it to be classified as a US government "secret".

The press and the professional comedians had a good time mocking the US government for that one. But various people also pointed out that it wasn't the first time such idiocy had been enforced by law, in the US or in other countries. A long list of similar punishment for making publicly-available information public also appeared back then.

Maybe we can start a thread of other similar recent attempts to suppress public information. Do you know a good one in whatever country you live in?

Those might be grammatically similar, but the numbers differ by several orders of magnitude.

Humans really know mostly about multi-cellular critters, plus the tiny fraction of the single-celled species that interact with us somehow. Almost all single-celled species are yet to be discovered.

One of the more interesting bits of evidence is that all of the deep-drilling projects, which have sampled only a tiny chunk of the planet's crust, have reported single-celled living things "all the way down". It'll take a while for us to do a good study of everything living deep down there. Similarly, several deep-water sampling projects have turned up large numbers of unknown microscopic species throughout their water columns.

I guess this mostly goes to show how difficult it can be to do a good journalistic job of summarizing scientific work so that non-scientists can understand the actual results. "Ordinary English" (or French or Russian or any other human language) is sufficiently imprecise that it's very difficult to avoid misleading mistakes like the two summaries of this story.

Heh. Everyone except the folks who work with wood know that. There are some varieties of wood, e.g. ebony, boxwood, and ironwood, that are (usually) denser than water, and don't float. It depends on what percent of the wood is the little internal spaces filled with air. Similarly, there are some humans who don't float unless their lungs are completely filled with air. They're they folks without the fats that account for most people's buoyancy. (Here in the US, we have a lot fewer such dense people than we used to, so we had to repurpose the term "dense" to refer to mental capacity. ;-)

But your remark deserves its "funny" rating.

If it works in Kerbal Space Program, what the hell, go for it :-)

And they can't afford $500 for a phone or $800 on a game console but they still do. $1000 is within reach of enough people to be called "consumer grade". That doesn't mean everyone can afford it. Not everyone can even afford a computer, but we still consider them consumer goods.
