Snap used to have an advantage in terms of age group. I'm curious if this is still the case.

Anecdotally I've heard from my partner that Instagram effectively duplicated a core feature of Snapchat to the point she no longer sees the point of Snapchat. But she always saw Snapchat as a side novelty, largely because she used Instagram well before Snapchat.

But I also see this as an age group thing, Snapchat had the image of being popular with high school kids while Instagram had penetrated the university-30yr old category most effectively. So it's hard to say merely as an outside spectator. As well as being geographically limited in my perspective.
A lot of the cost and inefficiency of electricity is the storage and transmission over long distances.

Does anyone understand how the warranty works? From their solar panel page[0], it says that there is a 30 year warranty for Power and Weatherization and a lifetime warranty.

So, what does the lifetime cover? The only thing that can go wrong is that either the power module fails or the tile is damaged due to weather, which is both covered by the 30 year warranty.

Nevertheless, a 30 year warranty is still pretty impressive and even more so if it covers normal wear and tear from weather.

That sounds like a social nightmare. Complete dissolution of the concept of trust in society. And there is that much bureaucratic steps to get it on, it really may become an activity that's more trouble than its worth (vs the current worries of STDs and accidental preganancies).
I liked the content, but I didn't like the conclusion. If you have a strong belief I feel like you should be able to strongly hold (i.e. defend) it. The philosophy "strong beliefs, loosely held" will just breed rabid dogs that obey whomever has the most convincing evidence (note that convincing evidence is not necessarily strong evidence).

For example, watch this video: https://www.youtube.com/watch?v=Ag4HN_jeYV4

Purple is obviously the villain here, right? Grab your pitchforks!

Now read this: https://www.reddit.com/r/videos/comments/69xqxh/reviewer_ask...

Now it seems clear that the video creator was hiding something and that Purple is justified in their actions. Lynch the youtuber!

Now read the youtuber's response to that and be prepared to grab your pitchforks again...

I'm of the opinion that weak beliefs should be weakly held and strong beliefs should be strongly held. Something that you haven't studied yourself should be a weak belief, weakly held. Something that's only been on the news for a few days with very few actual facts should be a weak belief, weakly held (i.e. Ahmed Mohammed, Michael Brown, etc). Something you've studied or experienced over an extensive period should be a strong belief, strongly held since you are an expert.
I'm super excited about all of the great stuff happening in solar recently, but whenever I read about the economics of home solar, I'm also always reminded of how stacked the deck is for wealthy people vs. poor folks. There's a very large federal tax credit for solar investment. That's great...but, people who can't afford their own home get no such credit, and there's no way for them to get such a credit. That's a super common trait for lot of incentives; they go to people who need them least. And, the people who are getting these incentives, are also using a lot more power (bigger houses, more power), and so even with solar, their huge houses may still be contributing more to emissions than the poor folks who aren't getting any tax breaks living in apartments or rental properties.

I don't really have any answers on this, I just think it doesn't get talked about enough.
Really nice article! Succinctly demonstrates the problem with not using premultiplied alpha.

> As an Artist: Make it Bleed!

> If you’re in charge of producing the asset, be defensive and don’t trust the programmers or the engine down the line.

If you are an artist working with programmers that can fix the engine, your absolute first choice should be to ask them to fix the blending so they convert your non-premultiplied images into premultiplied images before rendering them!

Do not start bleeding your mattes manually if you have any say in the matter at all, that doesn't solve the whole problem, and it sets you up for future pain. The only right answer is for the programmers to use premultiplied images. What if someone decides to blur your bled transparent image? It will break. (And there are multiple valid reasons this might happen without your input.)

Even if you have no control over the engine, file a bug report. But in that case, go ahead and bleed your transparent images manually & do whatever you have to, to get your work done.

Eric Haines wrote a more technical piece on this problem that elaborates on the other issues besides halo-ing:

Yeah right.

Elisp was dynamic-scoping-only until version 24.1. That means elisp code written before that (i.e., 99.999% of emacs code that's not in C) as well as most of the code written after that, has essentially the feel of hacky cruft which will drown a modern programmer into an abyss of cognitive pain and headache when (s)he attempts to understand, modify, or debug it. (not unlike GOTO ridden spaghetti)

How many programmers have you come across that claim to use elisp as their primary programming language?

(to give you an idea, enough of emacs users/hackers are sick of elisp enough that emacs is now offered in two configurations: based on elisp or based on guile)
Going off grid means you need a lot more batteries, which need materials and energy to make.

Switching from gas to electricity for heating is a bad idea if there's still coal power stations in use, if you're not selling your excess power to the grid, they're going to turn on that coal power plant again.

Sharing power is a much better idea than trying to store it in batteries, unless those batteries are in a car
How on earth did you hit 80k? Using the calculator, the roof for a two-story 3000sqft home comes down to $50-60k, with a net gain of $5k. If your house is any larger than that, $80k is pocket change.
I have worked at shops where, without fail,

Any idea on whether or not this would improve your home's resale value? Also it won't let you go a full 100% (max 70%) of your roof coverage. Do they fill the rest with regular tiles?

The average person would have to finance this. So what's the true cost?

There's also the values of geographic distribution:

* on site transmission cost is $0 for power used

* the effect of a man-made or natural disaster in one location is contained: throwing a breaker for maintenance at the Arizona border doesn't shutdown power across an entire region: https://en.wikipedia.org/wiki/2011_Southwest_blackout.
I would argue that's a relic from the past. Most Instagram celebrities also had snapchat to post 'raw unedited' updates. Now that Instagram has stories, there probably isn't a strong reason to double post on snapchat as well.

Many of us do not hide our identities the way you feel compelled to, and do not dismiss Microsoft out of hand because it was cool to do so when we were in our teens.

You–on the other hand–are so confident in your opinion that you have made an incendiary shell of an account to troll people.

If anyone's on the take, it's you.
Not an expert here but a couple things come to mind.

From an environmental perspective, it is better to use surface area which is already built up than pristine natural desert land. The house itself already imposes an ecological cost. A solar roof adds around zero to that cost.

I've heard the stat thrown about that 50% of energy generated is lost to transmission. If that's true then there's efficiency to generation at home.

It probably doesn't figure into anyone's decision but decentralized generation leads to a more resilient "grid". As it stands we are potentially vulnerable to warfare/terrorism attacks on the grid.

Tesla the consumer brand is about being smarter than your neighbor. Wow you have a car which is electric yet more performant than my car? Wow you have solar panels and the aesthetic is better than mine? Wow you're completely off the grid? So much material for dinner parties. In short there is a good value of cool factor for amount of work. And there are people who break the market logic and bake their own bread, plant their own vegetables.

You're right that power from a solar farm will be an option somebody but for many people it's not an option yet. This is something you can do in the near term.
If you watch the advertisements and can actually act on said advertisements all is well with the system. However, if you have zero spending power, no influence and miss the ads... all is not well.

When are we going to say; What the hell is the point of this? Users "using" something doesn't make it profitable unless they are willing to pay you for it. Furthermore, advertising IS NOT working. Look at retail, malls AND name brands... Horrible performance for the bulk of recent memory.

For my address, it's currently showing 468k, and says that's a drop of 137k from one month ago. I'm positive that 468k is around 100k too high to be realistic. I bought for 265 in 2010, and I've been seeing units around me sell for around 350k recently. Redfin agrees with me, showing sales between 303 and 380, depending on unit size and upgrades.

Summary: Beta course to cover software systems safety from the perspective of DoD, attendees were contractors and civilians. Specifically covering MIL-STD 882E and related documents. Generally covering topics in software engineering and design that relate to safety.

It was a beta, and rough. The instructors were trying to be all things to all people. It hit too low level at times for the program office types who don't do any actual programming but need to know about design and safety considerations and processes. That was also (somewhat) redundant for the programmers in the group. It was, however, informative as we discussed topics related to this book (why I brought it up in class), and software engineering principles (from safety and reliability perspectives) that the new programmers and non-programmers weren't aware of.

The intention is to teach this material rather than rely on people absorbing it (poorly) on the job, which is how it's typically done now for software. Processes exist, but people don't understand them. Techniques get used, but people forget why. This is intended to raise the bar across the board (or provide an opportunity to) so that safety and is more thoroughly integrated into the design and development process.

I'm not sure what else to add. If you want to discuss more, I may respond here, but you can also email me (username at gmail).
There's not really a lot you can do about this though, is there?

It's not that hard to test that things work, or to see the failures. Comments I've seen like 'there should be a server that installs every package on its own and makes sure its tests pass' have a bit of an issue: we already know the issues exist. Having a big list of them in one place doesn't really give us a lot more information.

What's the solution? If you need to compile native dependencies, how do you take PyPI and Python packaging in general and make those native dependencies able to be portably compiled, reliably, on any platform?

Things that are straight up unworkable:

* Bundling native dependencies as binaries
* Specifying a single version of your native dependencies (the 'shrinkwrap' approach) and every library having its own
The tiles are proof against weather: if you saw the reveal video they dropped a heavy object on a tile without damaging it. Given that, offering a warranty against weather damage is basically free to Tesla, modulo manufacturing defects.

There is always risk. Maybe the price of electricity changes, or the laws change, so you can't recover costs? (Look at what happened in Nevada.)

Maybe Tesla goes out of business or drops support for this product? Maybe they aren't as durable as planned? Also, a roof is part of a house which is a very illiquid investment, and there are a lot of other factors affecting the price of a house.

But, presumably people aren't buying this just as an investment. If you're going to put a lot of money into a house anyway, maybe a fancy roof isn't so bad.
It's the right question to ask.

Home electricity costs around $0.15/kWh, while power plants sell electricity to the grid for around $0.03/kWh. The difference pays for installing and maintaining the grid and local distribution wires to your home. Depending where you are (I live in a forest, where a tree falls on the power lines a few times a year and they have to send out guys in a bucket truck to fix it) it's expensive.

Because of net metering, home solar panels effectively get paid the home rate. It's kind of unfair. If you have enough solar panels to zero out your home bill, you're getting something valuable (reliable nighttime power) that cost money (to install and maintain the wires) for nothing. But that's the system we have.

Sometime before we hit 100% solar power, the system will have to change.
What this whole thing about consent issues tells me is that the promise of the sexual revolution and free no consequence sex is bullocks.

Is it sexual harassment when someone gets someone to have sex with them by taking advantage of another's vulnerable state, or giving false promises, or has un-consented anal or other sex acts when only vaginal sex is consented to. How clear does a woman have to express lack of consent when in the heat of the moment?

These are not questions with easy answers and their inherent vagueness encourages jilted women to make these claims, horny men to act in ways that encourage these claims, and leaves administrators and officials straining to effectively and fairly evaluate these claims.

The way Western culture and Western sexuality and the expectations surrounding it are set up is pretty much geared for these sorts of sexual harassment cases to come up.

You apparently found it interesting enough to get to that picture, which is pretty far down in a fairly long article. That would indicate that it has some worth.
10-20% slower seems an honest delta, I can't blame a company for working more on their desires/ideas if they provide a standardized non crippled solution.
I'll prefix this with "I'm not a language design or modularity design expert". I personally would have preferred that JPMS was treated as an internal JVM/API concern. This still would have meant changes for IDE and tools vendors (rt.jar going away required rework for sure) but would have given more flexible options for a user space modular system to be build on top.

An example is that the Module definition file (Module-info.java) is in Java source code. Despite the compile time benefits (performance, security etc) this brings, it really locks down how user level module systems need to interact with this. I personally would have gone for a straight XML/JSON/Manifest.MF/YAML/Whatever format which wasn't tied to the Java compiler so tightly.
Oh, I've never seen that before!

We've never encountered this kind of MERGE-related race condition before, but I'm not sure that we'd recognize it if we did. Probably it would surface as a failed transaction, but our merges are pretty low-volume so it hasn't happened yet.

Sometimes I think bridging the gap is important. People rarely get offended when you talk about Humans causing an increase in carbon dioxide. It's not something they need to get offended about and the cause > result is obvious.

Okay, let me be completely clear: I think that even a comparison tool between license-incompatible maps is a bad idea. Better?

> Why does Microsoft continue to keep them walled off?

The question is backwards. The real question is, why doesn't Microsoft do what is necessary to bridge them. And the answer seems to be simple -- developer man-hours are limited, your use case is not the use case of the majority of people who want a Microsoft development environment on a Mac, they are handling the most common use case, not the edge case.
short answer: nope. cockroachdb replicates data for availability and in order to guarantee consistency across the replicas, it uses Raft[1] internally. Raft necessitates a majority of the replicas remain available in order to operate. it ensures that a new 'leader' for each group of replicas is elected if the former leader fails, so that transactions can continue and affected replicas can rejoin their group once they're back online.

Doesn't the Tesla roof last substantially longer? Like maybe 2-3 times as long as asphalt ?
This doesn't address the problem of how to deal with someone who doesn't WANT to correct their worldview.

That's the real problem.

I start off too many conversations with: "Look, if you want to talk about <position>, fine. However, you have to tell me up front what evidence you will accept that your position is wrong. If you can't do that, then this is a harangue and not a debate or discussion."
Because, of course, you might expand it later.

Sure, I'm adding this shitty console based logger, but since it's wrapped in ILogger I'll later come and write a FileBasedLogger, a DBLogger and a KafkaProducerLogger for when we go webscale.

Except, that never happens.
Maybe it would help to think of the credit as benefiting the solar industry more than wealthy people. It's a long road for new tech to reach economies of scale. If society has an interest in reaching that inflection point than the subsidy could be money well spent. Poor people will benefit when the price of the roof falls further; it may never have reached that point without early subsidy.

Perhaps it would be more equitable if Tesla received the subsidy directly. But that places the government in the business of choosing winners without the market signals of who would actually succeed if given the subsidy. Politically that's such a minefield. And no one ever lost votes for promoting a tax cut.

I don't know anything about this overall, but I have some interesting anecdotes that show the power of Facebook around the world.

I've done some pretty substantial traveling throughout Asia, and just about everyone with a smartphone that I've met also has a Facebook account (excluding China).

In Myanmar (aka Burma) the strict military government restricted internet usage until they turned over control of the government last year. Most people are (within the last 12-24 months) using the internet for the first time! Most have never used a computer, and they only know the internet from an (Android) smartphone. However, every single person who I talked to there who had a smartphone had a Facebook.

The one local I talked to most in depth about this had never used Google! He said he didn't know how to use Google, and he didn't think he needed it. I explained what Google can help with: searching for information, reading news, etc. He showed me that he read news and did searches for things all from within the Facebook app.

I saw similar usage of Facebook in other developing Asian countries (Nepal, Thailand, Indonesia), where people used Facebook as a kind of substitute for a web browser / search engine.

You and I would never think to use Facebook as our internet portal, but it seems to be a very sticky and powerful tool for many of those just coming online.
The Genius Hiding in Plain Sight
They have my house around 680K. If I were to guess what I could really sell it for I'd guess around 580K, based on a recent nearby sale. My house is a little odd and there aren't many good comps for it.

At one point a few years ago the Zestimate was about 540 and my house was appraised for 450.

And when we bought it 5 years ago the Zestimate was at 380 and we bought it for 420.

I once heard to expect the Zestimate to be off by ~20% in either direction. That seems to be holding here.
Python/Ruby/Node all suffer from this - the OS stubbornly thinks it knows what's best. Here's what I do.

1. Ignore the OS when developing - let it manage its own dependencies for its own Python - fine. I use pyenv/rbenv/nvm to install my own dev. version of <language> and use isolated virtual environments for developing.

2. Deploy using Docker - again - ignoring whatever the OS has installed.
