You think too much about details. It wasn't supposed to be taken literally, I'm not talking about NZ in particular, yes, Australia's case was taken for inspiration, and, yes, I'm aware of RHDV1-K5 not being artificial per se.

It actually feels weird to explain that and, no offense, but I think the fact you are taking it so literally is actually the essence of what I'm trying to say here. The details don't change the general fact we have a history of fucking things up, because "we know science" and "have verified all the details". And the silliness of all the mistakes of the kind I'm talking about here is essentially the same — while fully admitting we don't know all the details, some people are too eager to ignore that and to feel self-righteous on the basis of checking all the known details and not seeing a problem.

This isn't about RHDV1-K5 — if I had some serious educated concerns about it, I wouldn't voice them over here (at least not only here). Maybe there won't be any problems this time, I don't know and I surely hope so. But we have a solid track of proving otherwise and, I'm sure of that, we are not done with making mistakes yet.

It's a shame but far from unexpected. My local hardware store shutdown about 8 years ago: the sort of place where you asked, expecting a no, "don't suppose you've any toggle switches?" and they passed you a battered cardboard box with 20 different types in then made up the price on the spot.

Didn't discover Maplin really until after that place closed. Useful to have close, but I barely ever visited.
Why are you looking to cut cable? Most people claim its cost, but if you are an avid tv watcher, cable is not a bad deal, especially with the bundles available and in certain circumstances is cheaper than the streaming alternatives.

We cut cable for a lot of reasons that may or may not make sense for most people.

1. My wife has a split shift and has a lot of down time during the day. When she isn't at the gym, she can just watch her shows on her phone.

2. We have unlimited gigabit internet for $70 from AT&T. If you have capped internet, it either costs extra to get uncapped internet or it's not available.

3. We have alot of TVs - our room and our son's room, the guest bedroom, home gym, living room, and my wife's study. That would be $50 a month by itself in set top box rental fees. Instead we have three Roku TVs, two Roku sticks, three third gen AppleTVs* and one 4K AppleTV (free for paying three months with DirectTV) the interfaces are much better and with the Rokus, I can stream the audio to my phone with headphones while watching TV.

4. We have gigabit Ethernet jacks throughout the house. We don't have to worry about flaky WiFi for streaming.

5. Very few markets have streaming alternatives where all of the broadcast TV channels are available live. I live in a market where they are available with DirecTVNow.

I’m honestly not sure. I think it would be a tiny fraction of what they were trying to target, but it does seem to be growing with the whole maker movement. Don’t forget he UK has seen some fairly ambitious plans to get electronics into education (see microbit)

The tricky thing as a CEO/chairman would be accepting that you’re intentionally downsizing your company to maybe 10% of its size, in an attempt to survive vs staying at 100% and attempting to survive with the same old plan.

What about Evernote Business?
In economics, oversimplifying slightly, the market price is the equilibrium price. That is, where the demand curve and supply curve cross. This is the price the market will settle on without outside forces acting on it.

A subsidy results in a sale price below the equilibrium price while sellers receive payments above the equilibrium price. An excise tax has the opposite effect.

Different excise taxes on competing products may lead consumers to prefer one over the other, but still results in less consumption of both products than the market would without intervention.

If one is working on small (<= 15 by 15) matrices, the StaticArrays module [1] is also native Julia and is much faster than Base.Array. Since a StaticArray knows its own size after type inference, they are allocated on the stack, which is nice.

One downside is that unless you're doing BLAS-style operations, writing non-trivial transformations of StaticArrays always seems to require generated functions.

Anyway, I think this is a feature that numpy doesn't provide.

“Hello, I am CIMON”
So you’re suggesting injecting viral miRNA into the epididymis of parental mice and checking for symptoms of viral infection in the offspring? This won’t work because (a) the miRNA isn’t the whole virus, it probably won’t have a clearly discernible phenotype; and (b) the mechanism suggested here relies on specific vesicles. Export of small RNAs into vesicles isn’t an automatic process, it requires active targeting of the RNA inside the cells for export (RNAs essentially need to carry a “luggage tag” that directs the cell machinery to envelope it with a membrane and send it out).

Still, your fundamental idea has some merits. A more promising experiment would forego viral RNA and instead mutate the specific miRNA-206 in mice to carry a specific signature. Sequencing the resulting embryo in early development could show whether the mutated miRNA was taken up. I say “could” because there are fairly big caveat: miRNAs are short-lived (unless they are actively regenerated) and the concentrations may be too low to pick up a signal.

5x pay sounds quite regruntling, as in P.G. Wodehouse's "I could see that, if not actually disgruntled, he was far from being gruntled."

That’s a great question. I’ve been trying to decide if that’s the best way to go. I’ve built a metered plan internally that has the following tiers:

• 0 - 100 PDFs: $0.20 per PDF

• 100 - 1,000 PDFs: $0.10 per PDF

• 1,000 - 10,000 PDFs: $0.05 per PDF

• 10,000 - 100,000 PDFs: $0.02 per PDF

• 100,000+ PDFs: $0.01 per PDF

I don’t like that the customer is invoiced at the end of the month, instead of paying at the beginning. I was worried that someone would generate a lot of PDFs, and then their card would be declined. I might have spent a lot of money on hosting and wouldn’t be able to collect payment. For brand-new customers, I could also collect payments at certain intervals (E.g. $50, $100, $500, $1000, $5000.) After 2 months, I could trust them more and just have one charge at the end of the month.

I could continue to have monthly plans with quotas, and add the pricing tiers based on usage. If a customer knows that they will generate at least 100 PDFs per month, then they could pay a discounted rate at the beginning of the month, and save 30% on the first 100 PDFs.

I was also thinking that customers could buy “credit packages” at a discounted rate. This would useful if they are running a one-time batch job, and wanted to get a discount for the next 1,000 PDFs. The credits would also roll over to the next month, and I don’t think I would set an expiry date. I paid for some credits on KeyCDN, and it was really annoying when they expired after a year.

I’ll continue to think about this and A/B test different pricing over the coming months.

Anecdote: A few years ago I tried to buy some 555 timer ICs from a local Maplin shop. I knew that they had a basic stock of components in a back-room (not on display), but it took me nearly ten minutes to convince a shop assistant to even look for them, and what to look for. When he finally returned with a tube of ICs, he was amazed that such things existed and insisted on showing his find to some of his colleagues - like he'd discovered some lost relic. Never again.
> If you have access to the hardware that should be trivial to do: just implement a small undocumented flash memory space anywhere, then when the user taps a password an also undocumented firmware routine (that's hundreds of bytes, very easy to conceal)

I sincerely apologize for being this blunt, but you clearly have no clue what you’re talking about. Ask anyone who’s shipped any piece of hardware they helped design, let alone a processor, and they won’t be able to answer because they’ll be laughing so hard. Adding persistent hardware based spying like you describe into a design is anything but trivial.

One more thing to note. A friend of mine is recovering from a knee injury right now, and saw a fitness coach who came well reviewed. Unfortunately for my friend, the fitness coach didn't really understand the extent of ligament damage, and worked her way to hard, causing her incredible pain. The trainer had her doing things like squats, and she followed their advice (based on them being a professional). Again she saw a Physical therapist (different to mine) who gave her some actual recovery exercises and a training plan and she's coping much better.
Yet another article that went out and found the shadiest cheapest worst IoT devices and extrapolates in headlines that the entire ecosystem is that bad.

Where's the analysis of Nest? Where's the pentesting of SmartThings? Where's the article about how they tried 12 different ways to get into another reputable brand?

Don't think for a second that I'm saying anyone should get a pass, they shouldn't, but this to me seems like the equivalent of reviewing $3 luggage locks and talking about how insecure they are, then concluding that all locks are insecure and you shouldn't use them...

I will say that this article is better than most at keeping the criticism specific to these devices (except for the headlines), but they don't name the devices, so the analysis isn't doing any good (I still have no idea which device it is, and therefore can't protect myself by not buying it...)

It also uses the telling tabloid scare-word "skunk" as if it's some kind of devilish genetic engineered superdrug when actually skunk cannabis is just a indica-sativa hybrid that has a strong smell, not necessarily a strong THC concentration.

As a sad parallel, in Romania around 2008 when we had a massive influx of "legal high" synthetic THC analogs , the media scare-word for these highly dangerous synthetic research chemicals was literally "ethnobotanics".... Even now I can't contain my anger at this kind of willful ignorance spewed by what is supposed to be public information..

To me, [Syn,Lin]thesia are very useful when YouTubers don't have time to transcribe the thing into proper sheet music. Hari Sivan[1] and Kyle Landry[2] do this and often times fans may work together to make a proper sheet[2].

Music theory helps piano players understand musical pieces better, simplifying the complexity of piano pieces and reducing the time needed to learn new pieces. It turns "put finger here, then this one here" into "play this major chord progression in the left while the right hand plays a melody starting on the first note of the major scale..." and so on. Even just understanding how to make different chords (major, minor, diminished, augmented, dominant, etc.) helps tremendously. It won't be learned from either [Syn,Lin]thesia or sheet music alone.

Doesn't surprise me at all. Maplin is a terrible store. I haven't been in a while to be honest, but a lot of the stuff they sold there seemed like it was cheap Chinese imports. Their music and hardware sections seemed okay, but not very competitive. The staff like in most large retail stores were useless as well.

I used to work part time in a small independent computer store while I was studying, we sold a lot of the same stuff as Maplin, but we were 100% about the service. We knew people could get stuff cheaper online, but they couldn't get the service. You might know your WIFI doesn't reach the whole of your house, but you might not know what the best solution is. Do you buy a more expensive router, a different brand, a range extender? These are the kinds of things you'd be unlikely to find answers for in Maplin. You might as well just take a guess and buy something cheaper online.

People don't go to stores like Maplin just to buy things anymore. The business model doesn't make sense if you're competing with online retailers. You have to offer the only thing online retailers can't, service and peace of mind.

Yes not possible not enough complexity or stability for that matter and the energy levels required are well explosive the smaller you go the more energy is needed since you essentially go form gravity (macro) to electroweak (molecular and atomic) to the strong nuclear force (subatomic) and there is a pretty big increase in magnitude of the forces that govern interactions between each phase.

Heck even within the unified electroweak force there is a huge range e.g. burning coal releases he energy in the stored covalent carbon bonds which are tied by electromagnetism part of the electroweak force but if you start breaking protons a part from neutrons which is the weak force you get a nuclear bomb.

Life needs bonds that are cheap to create, cheap to break and ones that don’t explode once you do break them.
DNS Privacy, Authorization, [] and Root Structure: Time for Another Look?
The original advice was to use nouns to "identify candidate classes", rather than "determine classes".

Sadly when confronted with a problem, the majority of programmers can get no further than writing down lots of nouns, perhaps dozens of them, with no idea how to combine the few actually required into an object-oriented design.

OO isn't fundamentally about messaging. That is incorrectly assuming that object-orientation began with Smalltalk, Alan Kay and Dan Ingalls. Smalltalk's "messaging with objects, all the way down" approach largely ended with its popular use and the widespread adoption of Java. Java's object model is entirely based on Simula (James Gosling Sept 2017).

+1 for finding teacher.

I picked up piano when I was 25. After decade of playing other instruments being self taught I've decided to try to replicate formal education: basically I was taking classes intended for small kids (using private teacher), both theory, practice and study piece.

It was quite weird to play some weird kids melodies, but it was fun and being adult I was able to finish one year of child education withing one month. It was interesting experience and it really help me with understanding music.

btw I had to learn to play directly from sheet, which was something I had never done, so I've create small app to help me with that: http://notationtraining.com (you can even plug the midi keyboard for practice).
