Progress on legislating reform of the advertising industry has stalled. It remains perfectly legal for Coca Cola to suggest to an emotionally vulnerable child that drinking addictive sugar water will improve their social life. That's wrong, and more needs to be done about it. It's a problem that should be attacked from all conceivable angles. We need better laws (municipalities that have laws against billboards have the right idea), better adblocking technology, and more effective campaigns to identify, shame and shun people who work in the advertising industry. They should be social pariahs.
In every popular discussion advocating "renewable energy".

Let's give it a spin.

Given a solar operation that can produce 1MW continuous (under normal best conditions, including buffering for night, angles, etc), what happens when it's seriously cloudy for a week? we need to continue that 1MW output for 7 days. That requires 168 MW/h of storage. That would require 800 Tesla PowerPacks, totaling $116,080,000.

$116M just to make sure a 1MW provider (which really isn't much) can run a week with insufficient light (hey, sometimes it rains for a while).

Then, if the storm continues another day, all the power goes out. To keep electricity on for just one more hour would require another 5 PowerPacks @ $725,500.

What people don't seem to grasp about solar/wind + batteries is: when the battery is drained, you're done. No more electricity until the sun pops out again or the wind picks up enough, and no more buffer until those energy "buckets" can be refilled.

At this point, optimistic advocates will jump up with "but smart grids!" Yeah, well, show me the numbers. Convince me the national cloud cover I saw a few weeks back (lasting a week) won't promptly shut down the "100% renewables" providers in short order, leaving (say) Chicago completely incapable to achieve the needed 100 degree differential between outdoors and in (that was a very cold week).

The value of coal, nuclear, etc is that production keeps going regardless of weather. Renewable energy is absolutely subject to weather, and when the batteries run out, the lights go off.

i think you're confusing a haystack with a compressed straw bale - IIRC the fire resistance of a compressed straw bale is excellent. it singes on the outside but it's v difficult to burn through.
Agree, I just talked to as many people as possible. Started figuring out what problems I could solve, the personas / niches that are relevant, possible paths across the chasm.

Now, 6 months later, we've started a beta program and are exploring more rigorous methods for understanding customers, pain/value props, and adoption / retention

Sure, why not? I do regular automated validation of my backups against each other using "rsync --checksum --dry-run" and get notified if anything beyond a tiny threshold is out of whack. (The threshold being due to small files updated between the two backup runs)

As you can see below in those old numbers the amount of renewables is rising constantly. The actual number is now at 37,8% [0]

The fact that deals which have been done decades ago are something very hard to get rid of. It was very expensive with nuclear and it will be likely just as expensive with coal etc. but it's happening as I wrote above. All the more reasons why nuclear is just nothing to even mention if you consider energy in the future. It's a dead technology from the past and we'll have to face the remains of it for decades to come. We'll have to deal with it when the last coal power plant disappeared.

Processing the language’s abstract syntax tree is much less error-prone, for one. C macros (and any other text based macro system, including Cog) can be harder to debug than an AST version. While you could implement something complex, like list comprehensions in Cog, it would be a lot more complex and buggy than the AST-modifying equivalent[0].

That’s probably not what the author (you?) had in mind for Cog, but it is effectively a macro system so tying into the AST could be a big advantage. The only nice part about the text version is that it doesn’t presuppose a host language.

Oh geeze, this reminds me of the people who use perl to autogen a bunch of verilog (which is super common for whatever reason).

Just don't, instead find a macro system that actually understands your language.

:/ That is a bit disingenuous in a narrow but long country. Norway is only 6km at its narrowest (Tysfjord) but is 2,500km long (and 25,000km of coastline).

Of course, the USA is enormous in comparison, especially width wise.

Just curious. It looks like you formed Atomic Alchemy in 2018 and from the "YC W19" in the title I can assume you've been accepted in YC in 2019. Is this correct?

If this is correct, can you bring an already formed startup to YC? I have always assumed YC was targeted towards very young "I have a million dollar idea" type entrepreneurs, given that they require you to move to SA for three months for $150k in seed money.

In any event, best of luck.

You should consider developing a true hobby outside of work. When I was your age I got really into boxing (I had never really played sports before), and it gave me an aspect of my life that was much different than everything else, a new social group, and the opportunity to build confidence (both mentally and physically).

For you boxing might not be the right choice, in fact, it probably isn't! But something like running, climbing, weight-lifting etc.

I believe strongly that many young men benefit from healthy stimulus, often physical. Otherwise we get restless, bored, anxious, and depressed.
While it wouldn't support fuel use akin to fuel burning electrical sources on Earth, there are endothermic methods to pull molecular oxygen out of C02. In addition to the water electrolysis already mentioned, C02 can be partially reduced to carbon monoxide with artificial photocatalytic systems, or solid oxide electrolysis (with electrical input instead of solar input). Electrolysis would be counterproductive for primary energy, but rocketry only needs stored energy rather than primary. Otherwise, plants doing photosynthesis in a greenhouse could use C02 from outside the greenhouse. Photosynthetic production of oxygen would have side effects of useful agriculture, but that would be difficult to set up early in a Mars settlement effort.
Problem is you need enough "on standby" to run full-output indefinitely ... at a cost high enough that you may as well just use them instead of unreliable renewables.

Don't get me wrong, I'm all for renewables. Run my office near 100% on solar in summer, and run my home partly on year-round. My experience convinces me that while it's nice/fun/clean/etc, it's also painfully unreliable. People talking about renewables while living on coal/etc energy don't seem to grasp this.

All of this moderation stuff feels like a "damned if you do, damned if you don't" situation for Facebook.

People have been crapping on Facebook for making judgement calls on what's allowed on its platform. When Facebook does so without government backing, people get up-in-arms saying that it should be the government's role to decide free speech. But when the company goes and requests that government start doing that, people get up-in-arms about how it'll be "regulatory capture".

I can't predict what the outcome of all of this will be. I can however, predict that there will be an angsty article (Bloomberg? New York Times? Wall Street Journal?) decrying how Facebook is awful, evil, and incompetent.
I love using the Yubikey Neo with NFC, having my GPG Keys on it and using it also for SSH connections, but mostly I love it for the OTP Feature.

Mostly using it on my Nexus 5. It is great, because using it by NFC with Open Keychain and k9 I do not need to place my private key on the phone. Additionaly that works also great to use the Yubikey to unlock the Phone and also using it on the Yubico Authentificator for the OTPs.

That keys are really great. Love them.

The only other Tool I would recomend with similar features is the Nitrokey (https://www.nitrokey.com/) but the Disadvantage is, that they really lack on some features. But maybe a good alternative for GPG and SSH.

The advantage of the Nitrokeys are, that in compare to Yubico products they use open hardware.

Hope this helps out some people.

And, for everybody who is struggling on the usage, belive me, I spend over four years making everything work and some really frustrating time reseting stuff, building keys, fu*... up big and recover Accounts :D

> I've been saying that software engineering as an industry is in the caveman state of development.

I once bought a domain called "paleolithic-computing" (neolithic wasn't available, even though I used the stonehenge picture), to use as a blog.

We are indeed in the caveman stage. In fact, in some ways, we seem to have regressed. There is a pressure to release features faster and faster, and everyone knows you can achieve anything in a sprint, right? Then just get 'devops' to deploy.

It helps that most other (or proper) engineering disciplines have been around for far longer. We are not even comparable to egyptians building pyramids, we are still figuring out how to build huts (and rebuilding them every few years with new tech).

Give it time.

Well, I think that you're wrong because you're focusing only on the "census" area - this reflects in my opinion the typical "black or white"-tendencies/extremes or today's times.

I was trying to post a simple example - the event mentioned by the article is not the only occurrence and I guess that city halls had as well records about e.g. votes (which would relate a person to a specific party/movement/way-of-thinking), which would not be related directly to census but which had to be destructed as well.

I do not blame the census (and I agree that the pros of census overweight the cons). It's just that the infos that we can release today are not gathered and administered by the national-census-authority and that the their detail go in some areas well beyond what the census would gather.
A lot of these serious professions are independent firms that are appointed by a client. I think this can create a different set of incentives compared to working directly as an employee. The firm will be less dependent on the clients success than a direct employee. Your income depends on the quality of your work rather than one single project. And you are more able to see bias in decision making when you are outside of the clients corporate culture. Of course this probably falls down with very large contracts.
This got me wondering: if people are suggesting to trade posts for a free stay or meal, they must believe that their posts are worth something. So adding value.

In case this is not a one-of thing, but the way they travel, then they are basically professionally selling advertisements. Which is subject to value added tax.

So should the tax offices of touristy countries start sending bills to influencers?

TBH internetization of reality is still very much an ongoing process, likely to expand much further in the future. At least if we want to extrapolate, there might be a backlash, who knows (I can imagine internet gaining a boring, authoritarian image like television around the turn of milennium). "Big" political events had an important online aspect in recent years. New cultural phenomena, art genres etc. emerge here.

I have to admit, imagining nuking the entire internet is funny intellectually. It would leave us with a low connectivity, low-res "slow" version of history, something more resembling "long 1990s" or what a stubborn pre-milennial person may still be experiencing now. Would it be warped beyond recognition? Probably not, not yet. You could still reconstruct Western societies in broad strokes. But I think the cultural history at least would suffer significantly.
The Well Intentioned Commissar (2009)
Fair - I meant title as a proxy for the work that's actually being done. My point was mostly that raw experience is only meaningful up to a certain point.

To be a bit longer-winded:

If you want to get paid more, you have to demonstrate value. Even if you only ever write the same CRUD apps, you'll definitely improve for the first few years, and it makes sense to pay more for a developer who isn't still busy making their first mistakes.

Past a certain point, though, raw experience isn't automatically a value add. If you're still just writing the same CRUD apps, you cap out a certain point. Now you need to demonstrate that you can contribute to architectural discussions, get involved in system design, or help with project selection/management. If you think you deserve the big bucks for that level of highly experienced work, that's totally fair, but you need some way to demonstrate it - whether this be tiles held, references, or having literally written the book on the topic. You can't just lean on "years of experience" anymore, because it's no longer well-correlated to value-added.
They're not extremely high, they're the cost of doing business.
Git9: Git Reimagined for the Plan 9 OS
I've configured gpg to use keys from "smart cards" before, and didn't really fall in love.

After the setup, things worked ok, but there were a few limitations that made me more happy with just having the key on my computer.

The primary was that I had no way to validate that the key material was encrypted at rest, and no documentation even appeared to make claims about how the key material was stored. My setup used a fairly long PIN to replace what would have been a fairly long password for decrypting the key material stored on my computer. I wasn't really comfortable with using something simpler as a PIN.

It may be the case that I could have leaned more on the hardware for security and told myself that the limit to the number of password attempts should allow for a shorter PIN to be used. But I was looking for something that I could add as another layer to my existing process, rather than something that replaced it.

At the end of the day, using a smart card to store key material just made it harder for me to reason about the security of the key material itself due to the increased number of unknowns. And it was more inconvenient.

Sure, if you are talking about engineers with 20 years experience, those numbers make sense.

But in the context of this conversation, IE people who use triple byte, we are likely talking about engineers with a couple years experience. (Yes, a couple years experience gets you the title of "senior" these days).

And within this context of engineers with a couple years experience who are using triple byte, I'd say that 150k is pretty alright.

You can see this data from the graphs that they posted, about how this is referring to people with a couple years exp.
No worries at all!

Regarding the technology comparison, that is true from a power system point of view - but for a utility which is making investment decisions in new generation capacity, it isn't so different. We include carbon taxes because coal power operators suffer that tax, it isn't an assumption about future policies. And equally to someone else's question about whether subsidies are included in solar costs, the answer is no. Because the LCOE is calculated from current module, balance of system and soft costs, and that while subsidies have brought the costs down, they aren't a component of the LCOE. As for system costs which perhaps you are referring to, that is fair from the system viewpoint but not particularly for the marginal unit of new capacity. UKERC have done some good research in the UK on system costs of renewables integration which perhaps you are referring to [0].

But you're absolutely right that there is a lot of nuance, especially around regional power market differences.

Locke quote, for those interested:

"The acts of the mind, wherein it exerts its power over simple ideas, are chiefly these three: 1. Combining several simple ideas into one compound one, and thus all complex ideas are made. 2. The second is bringing two ideas, whether simple or complex, together, and setting them by one another so as to take a view of them at once, without uniting them into one, by which it gets all its ideas of relations. 3. The third is separating them from all other ideas that accompany them in their real existence: this is called abstraction, and thus all its general ideas are made.

I think this is a really interesting product, but I also find it really weird. Maybe I’m just getting older and this isn’t for me. It wasn’t that long ago that people actually had to have the courage to have a conversation. It kind of breaks my heart to think that a father (or son) wants to connect again but only if the other person does as well. That’s just not how that relationship works.
it's a market - the operator will order dispatch to meet demand. they add up all the offers cheapest to most expensive and figure out who the last unit dispatched will be. if your price offer is over theirs you don't get to inject into the grid and don't get paid. That's why prices tend to $0 if you _have_ to dispatch. Those at the margin run at a loss for a while and then make it up later.

I set it to `on`. I read somewhere on internet an argument why `fixed` is not really necessary: for setting it back to `off` you need the admin PIN, and you have only 3 tries (by default) for the password. So I am not really worried about someone managing to disable it. And that keep the possibility to change my mind later on open, without having to reset the key.
I think there really is something to an abundance mentality.

My dad used to hoard, of all things, toilet paper. Why? He grew up in WW2 Philippines, had his house bombed and had to hike up into the mountains where they would shit in the river and wipe their butt with stones.

The idea seems crazy to me and my wife, as does my Taiwanese-born in-laws' predilection toward hoarding food. But we grew up in a world where you can always go to Costco and get more. That wasn't the case even as recently as our parents' generation.

Similarly, today's teens are growing up in a world where you can always go to YouTube or Netflix and get more media, or Google and get more information. The idea that these might be scarce resources and you might need a personal collection, just in case the Internet gets shut off, is as foreign to them as the idea of running out of toilet paper is to me.

I recently wrote a different application for YubiKeys - using the YKOATH functionality to sign AWS API requests with HMAC-SHA256 (https://github.com/pyauth/exile). What I found is that Yubikey's protocol documentation is good, but their tools are pretty bad, and none of them should be used. Instead, I recommend talking to the smartcard interface through the lowest level library that's already bundled with the major OSs - winscard/pcsclite/PCSC.framework (three implementations all providing the same API).

The app I wrote includes Python ctypes bindings for all three implementations (https://github.com/pyauth/exile/tree/master/exile/scard, and https://github.com/pyauth/exile/blob/master/exile/ykoath contains an example of how to use them). Hopefully these will be useful to others writing YubiKey-based applications.

I should add, there are other YubiKey modes (like U2F) that use the USB HID protocol instead of the USB PCSC protocol. For those, someone at Google wrote this library: https://github.com/google/pyu2f which provides similar capabilities for HID-based protocols. It similarly interfaces directly with the system-provided HID API using ctypes.
Why not just keep the implementation of the solution to any question you might be asked in your pocket?
