Our girls had an iPad mini each since they were 8 and 9. No real restrictions except occasional 'no devices' days and evenings, or, "you've played with that enough time to do something else". I get to approve all apps, but I've never actually found a reason to refuse one. A lot of the games they pay are ad supported.

They're going to get exposed to ads whether I like it or not, and I'd rather they learned what they are, how they work and to just deal with and ignore them. You don't build up a resistance to germs by living in an antiseptic environment your whole life, and I think it's the same with ads. We make sure our girls have plenty of physical and mental activities to enjoy. Both of them love art and use our computers and iPads for drawing, sketching and painting as well as physical media. They're both musical playing the piano and flute, and occasionally play around with Garage Band and such but visual arts is their main thing. We encourage outdoors activities, they went horse riding for years but that's died off and they've both been in the Air Cadets here in the UK for about a year. To me it's about balance and encouraging responsibility.

We're very much guiding our kids childhoods our way, the choices we make for them open some avenues but inevitably close off others. That seems to be working fine for us, but I've got no problem with your way. They're your kids and I fully understand why youre taking the approach you are. I just don't think it's the only responsible attitude.
Document Manipulation APIs for C# .NET File Formats
I like my Rift, but I can't actually run content very well on it with my current hardware. I was hoping to upgrade my hardware this year, but GPU and RAM prices have been atrocious. Maybe next year...
it would be interesting to learn how it works and does what it does before i register. It says nothing about it on the homepage apart from a general idea which is good, but how is it implemented???

Just a thought but maybe if parents were willing to spend enough money for developers to make a living then they wouldn't need to resort to ads and IAP to make a living.

Often bring this up when I see people angry over how much their child spent in a random freemium app and the anger and vitriol they spew back at you is nuts, because they want their kids entertained for free with no catch.

High quality entertainment exists for kids out there, Nintendo Switch, Toca Boca tablet apps, etc. But yeah it actually costs dollars.
Thanks for at least trying to answer the question, just to be clear, I'm 100% convinced in climate change and some kind of extinction happening, just querying the '60% of all animals' headline.
Thanks for the feedback!

SwiftDemand is a fairly radical concept so initially I was worried that making claims too bold could come off as arrogant, but since we have now gained a lot more traction we should definitely revisit the copy on the landing page.

I like the conciseness of the 1 liner you proposed, the three sentence explainer is great as well, but we aren't necessarily looking to disintermediate the banking system, but rather to become a global currency that focuses on social economic good in the form of UBI.

A huge portion of our users are really focused on the crypto aspect of what we're doing. As we continue to gain a broader appeal we will likely de-emphasize the crypto part.

The struggle to communicate it was a problem with how YC perceives UBI due to their involvement in UBI research. They grasped the concept quickly, but the questions they asked were targeted primarily at whether or not it would be enough to actually support people, as well as my thoughts on current UBI initiatives rather than the market opportunity and underlying business. In short, they saw it as a charity and didn't dig deeper into the revenue model or vision.

Thanks again for your comments.
> I've been by hotels in Tokyo, Kyoto, and Mt Fuji all told me not to drink the tap water.

I've traveled all over Japan including those places and others far more rural and never seen that, it sounds really strange. Are you sure it didn't say you can drink the tap water? Maybe in broken Engrish?

Only places I've seen in Japan with warnings against drinking tap water is on trains and porta-potties.
I am not at all condoning a behaviour, simply transmitting an observation.
Was it ever proven wrong? Or just delayed by a bunch of last-minute technological breakthroughs?

Also, the problem is still here even if we maintain current population levels. It's here even if we do nothing, and in reality, we have 2/3 of the world desperately trying to grow their quality of life, which involves growing their energy use.
That's really indicative of a bad culture though. As a pilot, I use checklists and pre-flights religiously, and was appalled at the casualness and lack of safety consciousness eg on a sailboat or when scuba diving.

I've never done sky diving (why jump out of a perfectly fine plane? :-) ), but the culture & attitudes you describe sound scary. Well, at least people have fun and selfies (and, unlike a careless pilot, they (most likely) only endanger themselves). /s

But there is an even more dangerous, and more insiduous falsehood: "integers are encoded in some mysterious way that is useless to know".

EBOLA- WHY THE EUROPEAN COMMISSION GIVES MONEY TO FIGHT MILITIA IN CONGO?
Interesting.

2001 I lived half a year in Pune as a software engineer intern. I remember an auto rickshaw strike. I was buying books for myself and when I wanted to return I was stranded. I managed with a shared taxi and walking.

Perhaps because many employees of the company came from Mumbai I didn't experience Pune's typical standoffishness. I once was invited to a Pune home and the people were very welcoming and warm.
Honestly, efforts to run Java/Python/Lua/etc in embedded are more about retrofitting developers into that market than anything else, the fact that embedded devices get more and more powerful only enables that.

Embedded isn't unaffected by Wirth's law.
My equivalent of this is frogs. Frogs and the rhythmic noises they made at night were the "white noise" of my childhood.
For the nuclear industry, this is true as well. A lot of it is because of the original codes were written in Fortran, and thus there is some institutional lock-in even for new stuff. Everybody in the organization already knows Fortran, it's quite fast, and there are good libraries for doing all of the standard number crunching.

However, my unscientific and unsupported observation is that in fields that have emerged after Fortran went out of vogue as a general-purpose language, this same process happens again, but just with a more modern language. SciPy etc. are quite common in fields like genomic analysis, and I suspect that in 20 years, this will still be the case even if almost nobody else is writing new Python code.
These titles are pretty meaningless in my opinion. Plus, what front-end developer means depends on who's looking anyways. Where I work, for example, my official job title is Senior Frontend Associate. What does this means exactly? I haven't got a fucking clue.

But what boils down to on the day to day is this:

I'll spend some time, turning mockups into static pages using HTML, CSS (and the occasional sprinkle of JS), but the bulk of my time is spent on implementation -- everything required to go from static site to a functional web application. Together with the other "Associates" on the team, we'll do everything from cutting the UI up into components, implementing business logic to handle behaviour and user interaction in these components, talking to the backend, and managing application state.

So what we decide to call these roles isn't important. Rather, i think, we should focus on hiring for skills. This means that we should do a better job of describing the skill sets, that we are hiring for.

If you are struggling to find work, you should invest time expanding your skill. Trying to restrict some arbitrary title to suit your comfort zone doesn't help either.
Yeah, of course. Wish I could say the same for other comments.
This is a great guide for any leadership team of any business, not just Y Combinator applicants.
This is meant as more of a disclaimer than a selling point. A small portion of users sign up, collect their Swifts and are then confused why they can't directly withdraw them in USD. We can probably change the language to be more positive while still conveying that point though.
I could be entirely off here, but it seems to me this problem is less present when you send messages instead of call methods.

From the perspective of sending messages, the solution is that the knife object/actor sends a message to the cheese object/actor that it wants to cut it. the cheese can then respond to that message by changing its state to 'cut', or perhaps by sending a message back to the knife that it's not sharp enough for this particular chunk of cheese, and that the cheese remains in an uncut state. The knife actor/object could then decide to break, or sharpen itself, or whatever.

I haven't given this much thought yet though, so I'd love to hear how I'm all wrong about this!

A middle ground approach from my experience: whenever I would watch tv with my mother, back in the ancient era before Netflix, she would always, always mute the tv when the ads came on.

The ads were there, but we had that power over them.
What Is Power BI? How It Can Make Business Analytics Easy for Your Organization
Just returning from SF. I would definitely prefer this to Airbnb.
I've been wanting to create something called "Dev Nest" (or similar) for a while now (in my ever growing backlog). The basic premise would be that tech professionals with spare rooms provide medium term accomodation in exchange for part time technical expertise (design or development). So guests could see somewhere else in the world, experience the culture, and get hands on experience with a variety of startups and projects (open source etc.).

The main difficulties would be in ensuring expectations of hosts are clear so everyone is happy, and also IP. However, I think it's doable.

EDIT: There's also potential legal hurdles as to whether the accommodation is deemed payment for work. The whole platform would need to be extremely transparent to mitigate exploitation.
>So what’s the real fix here?

Dump the reviews? Perhaps return rates would be a better metric.
By an operator I just mean a transformation. Certainly linear operators like differential operators qualify. The fact that these have an algebra in their own right goes back to work in the 19th century by Felix Klein and Sophus Lie on transformation groups and to later 20th work on linear algebra and functional analysis. It's stuff pretty much everyone learns as an undergrad nowadays, but the fact that you can do algebra on operators hardly without thinking is a relatively modern perspective.

Not unheard of though. German politician Jürgen Möllemann, after running into lots of political difficulties and resigning, died parachuting in 2003. It's unclear whether it was an accident or suicide. (He opened the main chute, cut it off, and did not open the reserve. The AAD was not switched on. EDIT to add: When the other jumpers did a gear check, he went to "get a glas of water".)

> I implore you to be politically active, to consider support for candidates that at least acknowledge that there is a problem. Consider a carbon tax. Consider big, international efforts to clean up our oceans. Consider sexual education efforts in developing nations. Consider carbon re-capture efforts. There's a ton of things we can do, but we have to start doing

It has all been said before.

None of this is going to be easy when we have our governments frittering away money on the arms trade. It is violence and the threat of violence that enforces the current economic order. Therefore it is the trade in arms that needs to be addressed if there is going to be progress in other areas. The arms trade isn't just bullets, the business is also about 'cyber warfare' which means planting the post-truth news stories in the media that enforces the status quo for the arms trade.

People laughed at Martin Luther King for wanting to combine the rights he wanted for all people at home with the anti-Vietnam War, pro-peace ideas. They thought he would set back both causes and confuse people. History was not kind to those critics, we only know of Martin Luther King, the others were just shills anyway.

It may seem a bit of a stretch of the imagination to think that the acidification of the oceans or the fact that there are less than 7000 cheetahs left is going to be solved with things like nuclear disarmament and global treaties to abolish the arms trade. There will be those that think these issues shouldn't be confused and that things will not get better for the likes of the cheetah if focus is shifted over to the steps needed for a more peaceful planet. But why not give peace a chance? Every one of those billions of single use bullets could have been made into a reusable and recyclable rechargeable battery and you could have an extremely large wind farm instead of the F35 programme. We could go fully carbon neutral in a generation to make this planet a beautiful garden for all. But, for this to happen the arms trade has to be made extinct first.

There's really not much extra complexity: instead of usernames which are of the form tel:+31123456789, one could also support usernames of the form mailto:foo@example.com, urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6, along which canonicalisers & verifiers for each (the last might be some sort of internal Signal-scoped hash — I dunno).

Yes, it is some, but it's not a ton.

The only thing that you can do that will matter is convincing other people to do something.

The different model number may indicate a store specific version of that model. There is an appliance company I'm familiar with that has a reputation for low quality products even though they sell the same brands as everyone else. Sure enough, the model numbers of the versions they sell are slightly different to everyone else.

On a similar note, when buying a scooter for my daughter, I found the "same" scooter in Toys-R-Us and Walmart. Despite identical branding and packaging, the Walmart version was of noticeably poorer quality (different materials and so on). I didn't check model numbers / SKUs, but I would expect them to be different.

Redefining the Kilogram
Where is the state? What changes in response to the send? Here, it'd be the cheese, so it'd make sense to have the cheese be the receiver; but a real answer comes from moving further toward the Actor perspective. Given a distributed system with message passing, how do you choose to allocate locations to items of mutable state? That choice gives you your answer.

All single-receiver systems have a problem when faced with multiple otherwise-independent pieces of state that have to change in response to a given combination. You end up encoding various kinds of transaction to keep every member of the group on the same page.

Multiple-dispatch systems don't have that problem, but the tradeoff is that they're no longer message passing: all the "recipients" of a "message" live logically in the "same" location for the purposes of handling a given invocation, and if they're actually physically separated, the language implementer has to do the job of providing the illusion (e.g. via transactions) that they're in the same place.

I think it is linked to devices sold - and it is priced as percentage of the retail price. My understanding is that Apple do not agree with the price paid to Qualcomm being linked to the purchase price of the phone, which you can understand - why as a consumer should you pay more for the same IP if you want extra storage in your iPhone? I think this disagreement came around before Apple ramped up the prices with the X / XS / XS Max... We should have seen the canary in the coal mine :)

Working with sentiments
from a sufficiently misanthropic perspective that global human over-population is "the problem" , both methane release, civilisation collapse, and lack of budget to maintain or build infrastructure and systems like healthcare all sound like they are part of the "fix".

I don't really think it's helpful to talk about "the" problem, there's a big mess of coupled systems and most "moves" available to us have unpleasant side effects or unknown side effects on global or long-term time scales. we have a limited time and resource window where moves are still available.

The author's main paint is pedagogy of teaching C as opposed to industry relevance of C.

>The other day Neel Krishnaswami mentioned that he’s going to be teaching the C class at Cambridge in the fall, and asked if I had any advice about that topic.

Some googling found a C/C++ class by Neel Krishnaswami[1]. The description says 10 lectures so I'm guessing roughly ~10 hours of instruction. The prerequisites for the class are "none". You can also browse the pdfs of class lectures and past exams to get a feel for what the professor is teaching.

With that in mind, we then consider Regehr's advice:

>My main idea is that we need to teach C in a way that helps students understand why a very large fraction of critical software infrastructure, including almost all operating systems and embedded systems, is written in C, while also acknowledging the disastrously central role that it has played in our ongoing computer security nightmare.

The noble goal of "traps/pitfalls/disasters of C" isn't really possible to weave into an introductory course if a class is currently structured with ~10 hours. You have some hard time constraints there. You'd have to remove some topics ... e.g. maybe remove linkers?, STL?, metaprogramming? -- or -- make the class much longer ... e.g. more hours?, more homework?, more case studies?

An "Introduction to programming using C syntax" is one type of class that requires a baseline of time to each.

An "Introduction to industrial-grade software engineering using C best practices" is another type of class with its own heavy time commitments. Teaching the topics of correct/incorrect uses of C would take even more time than the learning the syntax of C.

Regehr's essay is well-intentioned ("hey, you should teach this very important topic <X-prime> related to topic <X>") -- but he doesn't actually tackle how to squeeze it all into a finite time-constrained class.
