ljcn··on The perils of using Internet Explorer as your default browser
They shouldn't be installing anything. Don't tell them the root password, turn on automatic updates, and forget about it.

My non-techie father has been using an Ubuntu 1604 LTS workstation for years with no trouble.

ljcn··on There and Snack Again: How to Eat Everything in the Lord of the Rings
No it uses scripts from parastorage.com (part of wix).
ljcn··on There and Snack Again: How to Eat Everything in the Lord of the Rings
Welcome to the web in recent years. Looking at my umatrix rules, for basic functionality a lot of sites need scripts from ajax.googleapis.com, [cdnjs.]cloudflare.com, brightcovecdn.com, static.parastorage.com (as in this site), and many other cdns besides.
ljcn··on New study: Google manipulates users into constant tracking
There are plenty of paid-for satnavs. Tomtom Navigation GPS Traffic (Android)/ Tomtom GO (iOS) get good reviews for motoring. Citymapper is free and great for public transport. I'm sure there are many others.
ljcn··on Modern Weather Forecasts Are Stunningly Accurate
Shout out to Climendo.

I use the android app and it gives me a simple comparison of 4-5 weather forecasts, an "average" forecast, and a "certainty" (a measure of consensus).

Obviously the average of the ensemble averages isn't as good as having the underlying ensembles themselves, but it's nice to see days when the forecasts agree and days when they have no idea!

ljcn··on 773M Password ‘Megabreach’ Is Years Old
If you're using a password manager you could generate a random local-part and store that too.

Think about units, tens, hundreds, ..., and stare at step 3 in the article.
ljcn··on How the 0.001% invest
Not refuting your assertion, but the concentration of power in tracking funds is a looming problem. The FT did a bit on it last week. Here's something similar from the motley fool:

ljcn··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights
This looks perfect!
ljcn··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights
It's not perfect but skyscanner.net does the first part of your description. I just did some test searches from Eindhoven + nearby airports, and it found routes starting in EIN, BRU, CRL, and ANR. By default it shows different take-off/landing airports.

Edit: kayak performs the same.

ljcn··on Oceans 'soaking up more heat than estimated'
Sorry I meant richness of the local ecosystem. Big mammals in particular.
ljcn··on The ISS Has a Supercomputer Never Mind the Fried Disks
Cool. The control machine seems like a bit of a waste though. Hardware degrades randomly even on Earth, it'll be hard to make any meaningful comparison with a single sample.
ljcn··on Oceans 'soaking up more heat than estimated'
> So there's no point to slowing down emissions.

> We need to adapt. To limit the damage, and fix things.

The first contributes to the second.

ljcn··on Oceans 'soaking up more heat than estimated'
> And also: how exactly do I explain to my children that the world they're growing-up in is in a dire state and soon may not even be able to support anything like a normal life for them? Ideas anyone?

They'll think it's normal, which is the real tragedy, but that's been happening for generations already. Your idea of normal is not as rich as your ancestors'. Wasn't North America abundant with wildlife when the Europeans arrived?

ljcn··on Intel ME Manufacturing Mode: obscured dangers and MacBook vulnerability
Isn't it fine as long as the secondary processor hands back once the initialization is done? Before the training the memory is unused, and only the "clean" processor has access to it after training. I can't see the threat.
ljcn··on Intel ME Manufacturing Mode: obscured dangers and MacBook vulnerability
They've managed to disable the Intel ME in their laptops.

ljcn··on All the plastic you can and cannot recycle
I believe (at least in the UK) that Tetrapak contribute to a recycling scheme (hence the Green Dot symbol - note it's NOT the regular recyclable symbol). With a bit of research I found a dedicated Tetrapak collection bin locally which we now take all our cartons to from time to time.

Things might be different where you are in the world.

Try "r:uk" instead of "uk" to set the region.

And relatively expert users too. I adore uMatrix but sometimes open a specific browser just to make a purchase, then wipe all trace of it.

ljcn··on Eerie Skyglow Called 'Steve' Isn't an Aurora, Is 'Completely Unknown' to Science
I think sametmax wrote a great reply already. I'll just address your logical fallacies.

Generalisation fallacy 1: "some harmful things are not banned; asbestos is a harmful thing; asbestos should not be banned".

Thankfully most governments are more nuanced with their regulations. In the case of asbestos, since comparable materials exist with less potential for harm, they are favoured and/or the more harmful stuff is banned. Where not possible there can be exemptions, e.g. see my European Commission link earlier, along with the "ban" it says:

> One remaining use of chrysotile has not been banned, however - in diaphragms which are used for electrolysis in certain chlorine plants. This exception is justified because no safe alternative has been developed and this process is carried out on closed sites under strictly controlled conditions.

Generalisation fallacy 2: "asbestos can be dangerous; if handled safely asbestos is not dangerous; asbestos is not a large risk".

Because it can be used safely does not make it generally safe.

ljcn··on Eerie Skyglow Called 'Steve' Isn't an Aurora, Is 'Completely Unknown' to Science
> The first documented death related to asbestos was in 1906, yet it was only banned a century later

Incredibly it's still not generally banned in the USA; only a small list of products are banned by the EPA federally.[0] It was increasingly banned in Europe from the mid 1980s, and totally banned throughout the EU in 2005.[1]

That was big news in Europe, e.g. https://www.bbc.co.uk/news/health-34615621

ljcn··on Verizon throttled fire department’s “unlimited” data during wildfire
Different beer (I think), but cf. the famous 1973 beer tagline: "Probably the best beer in the world".

Interestingly I would be surprised if that stemmed from onerous marketing regulations as suggested above.

Funny to see this 16-bit-plus-one range in the Laser Egg specs:

ljcn··on Why Salt Was So Important Throughout History
I agree it would be surprising if they were paid in salt, but the OED says

Latin salārium, originally money allowed to Roman soldiers for the purchase of salt, hence, their pay

ljcn··on The physics of infinity
It's been a long time since I've done any physics and there is absolutely no rigour here, but the (extremely useful) Dirac delta function comes to mind. You can think of it as being infinitely tall and infinitely thin, but with unit area. If you tried to divide the "area" (1) by the "width" (0), you'd get the height (infinity).
ljcn··on Inside the Linker (2012)
Indeed, retro. Not quite valid though unfortunately. Apart from the annoying character encoding, doctype, etc. problems, there's a </p> without a <p>, and a <ul> missing a preceding <li>.
ljcn··on Attack on the pentagon results in discovery of new mathematical tile (2015)
The einstein problem (lower-case E).

Not to be confused with the physicist.
