I tried going the sourdough route a couple years ago with limited success (about 25%). I have definitely learned more since then by just doing pre-ferments--primarily a poolish(high water % preferment mixed with a small amount of yeast and let sit for 14-ish hours, before adding additional yeast, salt, water, flour).

If anyone wants sour bread that peaks a few days after baking, but not the full levain/sourdough feeding regiment, I would definitely recommend trying a poolish (or biga). In getting the poolish down, I feel like I'm in a better position to retry sourdough, now that I understand what all the steps are for, and to treat time as an ingredient.

When you get in to it, one of your main problems will be always having a loaf of tasty bread on your counter. That combined with working remotely makes it easy to gain a few pounds.

Another recommendation with the poolish, is to use a 2 loaf recipe (say 1000g flour), then make focaccia's with the 2nd. Focaccia is extremely simple and makes for a great gift or something to show up to a dinner party with.

Well, it would be annoying in general (beyond this specific case, let's assume an instance we agree on) because it confuses an ethical stance with a factual statement. In this case, right with the profitable. Say that tomorrow we find out that more diverse companies perform slightly worse- what do you do? Do you change your opinion on diversity? I guess you don't, because diversity is ethically desirable, whatever its consequences. So wouldn't be more honest to say that we don't really care about the effect on the company's performance?

And for the specific case, I think it's very hard to prove that more diverse boards make companies more successful- there are a ton of spurious correlations and confounding factors, plus an understandable desire to obtain one result and not the other. Do you have any good research to point me to?
It's a fair point and simultaneously does a disservice to what China is very obviously about to accomplish with the C919.

There is every reason to anticipate China taking a big share of that industry away from Boeing and Airbus. They only need to buy their own supply (which they will) to do that.

Further, Japan is also very obviously about to successfully unleash the Mitsubishi SpaceJet.

It's like people that were still pointing out up to the last moments in May that the US had no human space launch capability, trying to wring that last bit of satisfaction from the context.

Not sure how authentic it is, but here [1] is an explanation:

> It is believed that it is caused by a virus/bacteria which can manage to take hold on a stressed octopus. The biting is said to be due to irritation and biting alleviates the affected area. An octopus can lose an arm without harm and regrow it. By biting it off, the octopus loses the infected arm and hopefully a healthy one regrows, but in captive situations, probably caused by bad water quality, the infection can't be shaken off.

> But when we talk about sending say, a spaceship into space, it may fall on a different planet, with a different gravity (a function of the planet's mass), changing the amount of energy yielded by the fall.

I guess you imagine there "failing" as something we experience on the surface of the Earth when we drop an object.

It's not what is happening when "sending a spaceship into space."

It's actually very hard (as in, one really has to spend a lot of energy) to get a spaceship to some star or planet. One can't imagine it as "just let it fall". I suggest reading the following article for the start:

https://www.forbes.com/sites/startswithabang/2016/10/01/ask-...

"Ask Ethan: Why Don't We Shoot Earth's Garbage Into The Sun?"

Much less energy is needed to shoot something out of the Solar system than is needed to send something into the Sun, even if you want "just" to send it there to burn. Nothing from Earth can "just fall" there, huge amounts of energy from the outside are needed.

What is actually happening is what already Newton figured out: when we're on Earth, we aren't aware of it but the whole Earth is constantly free failing towards the Sun, and yet we're not leaving the orbit around the Sun.

> Where does the extra energy, if the ship falls into a heavier planet, come from?

A lot of the energy needed for the ship to reach the planet has to be spent by the ship, for the current ships it is launched as the fuel with the ship and later "spent" by the ship (in reality "traded"). The ship can also "spend" the energy of other objects and that energy is really then "spent" (as in bookkeeping, debited to other account, that's what the conservation of energy and momentum is, a kind of bookkeeping) -- the object (e.g. a planet) is indeed slowing down a little, but the change is conveniently small enough:

https://en.wikipedia.org/wiki/Gravity_assist

"This explanation might seem to violate the conservation of energy and momentum, apparently adding velocity to the spacecraft out of nothing, but the spacecraft's effects on the planet must also be taken into consideration to provide a complete picture of the mechanics involved. The linear momentum gained by the spaceship is equal in magnitude to that lost by the planet, so the spacecraft gains velocity and the planet loses velocity. However, the planet's enormous mass compared to the spacecraft makes the resulting change in its speed negligibly small even when strictly compared to the orbital perturbations planets undergo due to interactions with other celestial bodies on astronomically short timescales."

In short, there's nothing "extra" happening -- all the energies and momentums are completely accounted for for everything that happens on the scales reachable to our spaceships. The only energy we can't account to anything else is the one we call "dark" but it is observable just in the movements of the whole galaxies, on the scales practically unreachable to our spaceships.

"Non-profit" doesn't mean you don't make any money, it means you spend all your money. I went to a tiny liberal arts college you've never heard of, with a 1300-student enrollment today. The president makes well over half a million dollars a year. There are half a dozen deans making anywhere from $75-250k. A career services department run by a six-figure employee who has never held a job outside of that college (for real). They're technically a non-profit but with a sticker price of $40k a year and actual per-capita revenue somewhere in the high $20's, that is a lot of money to spread around to administration while you have 150-person lectures taught by a $25k/yr adjunct.

Listen to this. Sales and marketing mean nothing without a product.

Focus on creating value. You use this value to market and sell.

> Someone has to come up with criteria based on whatever goals and values they think are important.

The most obvious criteria is: most likely to graduate.

Some others that aren't bad:

* Highest expected value of future donations

* Highest expected value of impact (publication)

* Highest expected value of future salary

* Highest expected value of holding public office (the weighting here might be contentious)

As long as all of the criterion are achievement based, I expect them to screen for roughly the same people, demographically.

See a few comments mentioning me (the developer :)) so here goes ...

When I started working on newCo I was working on it my spare time. I decided it would best for newCo if Ben was able to focus on it fulltime, instead of splitting the revenue with me, then having to supplement his income with other work.

To be clear Ben was willing to share the revenue with me at the time. I was in a place where that wasn't necessary and I thought it would best if it went to Ben until we hit certain milestones which we never did.

MakerPad was something totally new that Ben started after we decided to fold newCo, he did 100% of the work for many years, and deserves all the success it has brought.

Ben is a friend, and I'm happy I was a part of his "startup" journey. I'd be more than happy to work with him on projects in the future.

I go into all my projects with a clear mind, knowing what I'm risking (usually only my time).

I use it as an advanced text editor on any Linux or BSD workstation I use. I'm not a developer so most of the IDE type stuff goes unused, but I do like having something as powerful as Notepad++ on Windows without resorting to cumbersome editors like Atom or VSCode.

I’m not sure what my problem is, but I find it incredibly hard to focus on some things for any meaningful amount of time.

For example, I’ve been diving back into C recently and going through and exercises takes me forever.

I notice I’ll do one, switch to YouTube to swap song, find an interesting video about literally anything, watch that, and then do another exercise.

I’ve looked at ADHD but I’m not sure I fit, in pretty good at getting my work tasks done by the deadline, but if I focused I could probably do them a day earlier.

> a person who's attending school in order to improve their lot in life (because credentials count for so much)

If every person at the school had this reasoning, the credentials wouldn't count for anything.

The credentials only count for something if enough of the people graduating are actually fulfilling this promise of self improvement in the subject of their studies.

The cheaters are literally freeloading off the prestige of the credentials produced by the people who do put in the effort. If that group of people did not exist, the credentials would be useless to the cheaters as well.

In my previous job in a consulting company one of the sales people mentioned how this is the first place where he has to sell the project twice: once for the customer, and one for the co-workers who'll work on it.

It was a nice company. Bosses had very limited direct power over the developers and designers, and rightfully so -- it's supposed to be a team of experts, after all.
The lesson is just because we think, with our big wonderful brains, that something isn’t going to work in the market, doesn’t mean we’re right.

Or to say it another way, the lesson is that business people have jobs for a reason too.

Or: if your job is computers, focus on the computers. For me, I don’t go around my company telling everyone whether their projects are going to take off or not. I assume the research a team did prior to starting gives them a familiarity with the problem space that I lack. Crazy thought, I know.

My problem with QED/QFT is that it gets about five levels of abstraction too far from physical intuition and then really starts layering on the algebra. At the end, it's totally abstract and I very strongly suspect (but cannot prove) that nobody knows what it all means in the end.

My current pet project is to try and write a "renderer" that uses QED, or better yet, some more advanced subset of the Standard Model instead of the oversimplified "raycasting" model typically used in computer graphics. I'd be happy with a "quantum" Cornell Box, ideally in a fully relativistic model that can simulate the speed of light, diffraction, interference, etc...

I'm trying to see how far modern physics has gone and still be in contact with a fully general, numerical, real theory. Not just the abstract properties of statistical theories, if you know what I mean.

So far it hasn't been a fruitful journey, I can't even find a reasonable description of an electron's U(1) field equation as described by QED. I get that it has a bunch of properties such as its symmetries, transformations, etc... but this is like the description of an elephant by a blind man touching each part.

>Don’t single Tesla out on this. No car manages to get its official mpg/EPA rating in real-world driving conditions.

It totally depends on the vehicle. I maintain a fleet of ~10 vehicles and keep records of fuel economy (because it tells me when calipers stick before the drivers do). The vehicles get ridden decently hard and pretty much all the highway miles are in the left lane at whatever speed that may be. A 2/3 majority pretty much always exceed their EPA rating by 2-4mpg. The rest are right on the rating. None of them spend much time in the gridlock that tends to characterize upscale inner suburbs during daylight hours nor do they cruise empty rural highways.

With the right conditions, you can store LSD indefinitely (well, until the end of the world or similar).

"on Mars, a pressurized dome actually supports its own weight and then some. As a result, the structure is under tension and the dome is attempting to tear itself out of the ground. Since lifting force scales with area, while anchoring force scales with circumference, domes on Mars can’t be much wider than about 150 feet, and even then would require extensive foundation engineering."

Huh, I always knew you could "float" domes from reading Red Mars but the lifting force sounds pretty gnarly.

It's not about just doing the dishes, it's about the sum of all the other chores and things you have to do. It's overwhelming in its entirety, not the individual tasks.

When they look at the washing up a procrastinator doesn't just see the washing up, they also see that they have to do a laundry, fix the cupboard creak, do a full clean of the cupboards, clean under the fridge, wash the floors, dust the cobwebs, fix the dripping tap, take out the recycling, decide what to do with those old jars, etc., etc.

Even if they do eventually manage to do a flurry of chores, and usually feel great, it's not a habit to do it again. It's not a scheduled minor, automatic, task. Your brain deals with habits much easier than things you have to consciously do.

So it inadvertently builds up, and BAM, as if from nowhere, there's a massive pile of washing up with a whole load of OTHER tasks mentally attached to it again.

You see it as easy and lazinness, but we don't. The irony is that living like this is actually a lot harder, you're having to ultimately put more work in for often worse results.

Will be interesting to see how ML and CRISPR converge. Two systems we don't fully understand creating explicit capability we desire and latent capability we don't expect.

I'm curious if there will eventually be some kind of biological incarnation of cellular automata that is useful for chemical synthesis or material fabrication. Clearly we have that with individual organisms now (e.g. insulin manufacture) but imagine seeding a matrix with bacteria that extrude carbon nanotubes under UV light or similar oddities.
Having different batches reduces the risk of multiple devices failing at the same time. There's a higher chance of devices from the same batch failing simultaneously (due to the same material or fault during the manufacture) than from different batches, or even better, from different vendors.
