I would recommend reading this article by The Guardian on palm oil: https://www.theguardian.com/news/2019/feb/19/palm-oil-ingred...
(It is also available in podcast form)

From the article:

> Most importantly, it gives the highest yield per acre of any oilseed crop – almost five times as much oil per acre as rapeseed, almost six times as much as sunflower and more than eight times as much as soybeans. Boycotts of palm oil will only lead to its replacement by other crops needing far more farmland and likely more deforestation.
Not Being Stupid in Entrepreneurship
”””These animals seem to uncritically follow the artificially stimulated behaviour as though it was 'real' or original to them. It seems a reasonable suggestion that, perhaps, a human would be able to distinguish it from an original memory.

Are you suggesting that is wrong? If so sure, explain why.”””

What you describe is behaviour I observe in humans. I wonder if I demonstrate such behaviour, and how I might find out. To the extent that I am self-critical it has been by observing that other people are not.

When I was a teenager I was interested in the occult, and had several experiences which seemed totally real at the time, but which I can only explain now as self-hypnosis — while my accidental Philosophy A-level taught me not to believe everything in the New Age section of the bookstore, my mother continued to believe that Bach flower remedies could help her memory right up until she forgot what those “remedies” are because of encroaching Alzheimer’s.

My earliest childhood memories are 2/3rds dreams and I only found out by asking my relatives about things which occurred within them, not by introspection.

And then Brexit, where… well I can say with high probability that half the country believes the other half is out of touch with reality, and vice-versa, but all the online arguments seem to show each side accusing the other of uncritically parroting cliches.
That must be what I was thinking of, thanks!
> Just because an animal can't tell the difference between the real and artificial memory does not mean a human couldn't do the same.

In the same way, we can't tell humans can do it without testing the hypothesis first.

If animals can, probably we can, if animals can't, it's possible that we can't as well.
Bit late to reply but regarding the advantages of not allowing rebase operations in a distributed system: if you can only change the version tree by adding nodes to leaves and by adding attributes to nodes (e.g. for merge arrows, tags, etc.), then combining distributed changed versions of a version tree is relatively trivial and users need never fear pushing and pulling.

Or more formally, there is a partial order on version trees (inclusion) and if all changes to version tree are monotonic with respect to this partial order, then it will always be possible to combine distributed versions without conflict.

An analogy might be that I prefer storing raw facts in databases, where practical and performing aggregations/filtering/etc. as queries during retrieval rather than storing filtered and aggregated data.

Typical rebase operations like squashing commits or removing merge history destroy information. Rather than decide up front what information is interesting, why not keep it and provide better tooling for filtering and aggregating commit information?

And what I'm suggesting here isn't radical - other VCSs offer branching and merging without requiring operations similar to rebase. Git itself supports such a workflow and many tutorials introduce git with a simple workflow that does not involve rebasing. I've used such systems in the past and because they had decent version browsing tooling, there was very little "noisy history" overhead. If you wanted a linear view of a branch like "master", you could view the history that way; if you wanted to drill into the branches, sub-branches and merges involved in a particular "master" version, you could do that also.
SBCL is a strange Lisp implementation, since it does some compile-time type checks, too.

* (defun id (f) f)
ID
* (declaim (ftype (function (fixnum) fixnum) id))
(ID)

Our new identity function is declared to be of type fixnum -> fixnum.

* (declaim (optimize (safety 0)))
NIL

Now we've set safety to 0.

Let's define a function which calls ID with a string

* (defun use-id (s) (declare (type string s)) (id s))
; in: DEFUN USE-ID
; (ID S)
;
; caught WARNING:
; Derived type of S is
; (VALUES STRING &OPTIONAL),
; conflicting with its asserted type
; FIXNUM.
; See also:
; The SBCL Manual, Node "Handling of Types"
;
; compilation unit finished
; caught 1 WARNING condition
USE-ID

Even though safety is 0, the compiler warned us about a compile-time type problem.
It's also important to understand that entry into the US is not a right for non-citizens and suspicion is generally enough reason to kick someone out at the border.

I don't think its fair, but traveling to another country you're not a citizen of you have no reason to expect fairness. We don't expect free access to other sovereign countries. For instance, and China has a long history of kicking out foreigners for arbitrary reasons, targeting foreign bars for random drug testing, etc, and this is considered acceptable because that's the law there. Here, we don't target foreigners/outsiders (laowai) so harshly. We treat foreigners way more kindly than most countries. We still give out tons of visas every year to allow people various opportunities. What the CBP can and can not do is also dictated by law as a security mandate. The law says people can be denied entry for a variety of reasons. Until we know those reasons, if we can possibly tell those reasons, there isn't much to say.
Ask HN: Courses or Books in Better Writing
Hi All,

I am looking for any good Courses or Books on better writing. I have been writing a few pre-read documents for pitches/proposal for my startup and I don't feel they quite hit the mark. I asked someone to help me write what I was thinking and the output was fantastic but they wouldn't really tell me how they did it. They said it was just repetition of doing documents. However, I kinda need something to start with.

Has anyone read any good technical documents aimed at business or done any good courses?

Thanks
Oliver

And how's that supposed to work exactly? A court room in the airport to deal with all cases. That's simply not practical. You go through any border at any country, and if anything seems off, they have a duty to deny entry. That's the law and that's how it works.

Thanks for exemplifying how parents can deal with the issue while being not too lenient nor too strict.
Yes, but like parent said, we're starved of time. I would love to bike or take public transport to work but that's over an hour of commute vs 20-25 minutes by car and I don't live in the middle of nowhere but in a medium sized European city.

The problem is the employers who move to the sticks, far away from the cties, where office space is cheapest and assume their workers can afford cars and should commute. Not only that but they actively fight against remote work saying it destroys team effort.

One huge step in the right direction would be governments incentivizing employers to accept remote work for office workers who's jobs are 100% digital. This way we won't all be clogging the streets at rush hour making commutes easier on those who have to drive.

Heck, one friend of mine broke his leg skiing and his company, instead of allowing him to work remote, prefered to pay his taxi fares to and from work for 2 months saying WE DON'T DO REMOTE!. And the company is a top EV supplier that loves to boast how green they're making the world. You can't make this stuff up.

Option 4: output square wave power instead of sinusoidal and hope you don’t destroy the downstream equipment.

In practice, isn’t most of that storage used as part of a boost converter to get a higher output voltage than you input? You either need to switch capacitors between series and parallel or feed a step-up transformer with low-voltage, high-current A/C, which ends up being enough copper wire to get heavy and expensive.

It feels like there should be a change in international IP laws to address patents as wide as this. I mean, in this case, even without expert analysis, I feel these network layer patterns can quite easily be likened to the widely used Gang of Four design patterns, or perhaps other concepts that have a highly technical basis. Like lenses, for example.

More precisely, network layer pattern descriptions surely lie in the class of a fact or discovery - https://www.prv.se/en/patents/applying-for-a-patent/before-t... - which should make the claim close to unenforceable at any level.

Unless the patent we're discussing covers a very specific implementation, which is uniquely efficient.

From the article,

The problematic part with PostgresSQL JSONB is modifying a JSONB column content. In any case, we totally replace the old content by a new one. So, the update operations turn to the complex queries that can lose the content. You can avoid this by performing the full JSON reorganization before the persistent operation.

You still don’t have the richness of MongoQuery and the aggregation framework and the tooling around working with JSON data isn’t there. Let alone the native driver support.

So the traditional behaviour of 'key repeat' has been replaced by 'long press context menu'?

My initial reaction was one of revulsion ("Why do they need to meddle with everything") but after taking a few moments to calm down I realised I could get used to that change.

I think to make it attractive, I would want a quick way to switch between behaviours when I need them. From what I can see, the change between 'long press' and 'key repeat' is effected by launching Terminal, making a configuration change and restarting the machine. I find this unappealing.

Getting a speed bump added to your street is nearly impossible in LA. I lived on a street that badly needed one. It was a double length block paralleling Wilshire, so frequently used as a bypass with many speeding drivers. I looked up the process for requesting a speed bump. They only take so many requests per year, so I had to wait a few months for the request form to open up. I marked my calendar and when the date came it required that you get signatures from 50% of the residents on your street. Since my street was almost entirely apartment buildings and a double length block, this would have been hundreds of people. I gave up. I no longer live there.

It's a worry for people who choose software that they need to work in the future full stop. As someone else pointed out elsewhere in the thread, this is being removed partly because the previous open source version of MongoDB no longer builds from source, apparently due to some change to the toolchain or libraries. Normally you'd upgrade or backport upstream's fix, but that's no longer possible in a situation like this.
It’s not possible IRL.

I guess my definition of open source is that you can read the source so you theoretically know what you're getting or if things don't go the way you want you can figure out why.
This means that open source could theoretically be free as in Mel Gibson shouting but not free as in money found in between the cushions of your couch.

That said I dislike MongoDB but for various other reasons.
Perhaps the Gnome desktop. As a big fan of the 2 series I don't know what the goal was with the 3 series. More dumbed down than mobile OSes... I took refuge with the KDE project, which, with Plasma 5, really got into its own, but Mate is a good alternative as well.

Gnome, I know it's the default on most distros, but I can only imagine that is because of inertia. Who ordered what Gnome 3 offers?

> Primarily vegetarian diets and less driving would make mountains of difference for the world.

No, it wouldn't.

Look at pandas, they are bears (omnivores, like us), living on a primarily vegetarian diet.

They sleep 16 hours a day and when they are awake they eat, because a vegetarian diet is not really energy efficient.

If we are talking about a true vegetarian diet, environmental friendly.

if we are talking about "I can be mostly vegetarian because I buy integrators from the drugstore" that's the same of eating fried chicken intensively farmed 4 times a day, in large quantities, for the environment.

What most western cultures should aim for is eating raw food, completely avoid processed food and, most of all, EAT LESS.
I don't disagree that a train that can tolerate a wider range is desirable, but lots of things are desirable. It's also desirable to give everyone their own carriage, or have a free bar on every train. But at what cost?

* Wider tolerance means heavier electrical and cooling systems, increasing both capital outlay and operating cost for both track wear and maintenance.

* The trains procured were essentially "off the shelf" from Siemens and would have been designed and manufactured for other operators before the DfT put the tender together. A wider operating tolerance would have therefore either ruled out the Siemens trains, or at least significantly upped the cost as they would have had to redesign them.

An annual season ticket from St Albans to London is about £3,600. How much more should that passenger (as well as the taxpayer) be paying so that they can travel on trains that work when this type of event happens? How often does this type of event happen?

> This is utterly inexcusable for a train given the amount of disruption caused by multiple lines being clogged by failed trains in multiple places.

People being stuck on trains for a few hours is pretty far down the severity list of "things that could go wrong" when the power goes out. That said, what I do think the outcome will be here is they'll figure out if/how the driver can self-reset this type of issue rather than requiring a fitter to travel out.

transforming to a higher or lower voltage can be done with small capacitors / inductors (just switch at higher frequency, for each doubling of frequency you can halve the capacitance and thus cost of capacitors / inductors)

but given a desired AC output wattage implies a specific output power, cycled at twice the line frequency, so with only 1 outlet you need to either throw away half the solar power energy, or have storage capacitors or inductors to store energy for the timescale of the line frequency (which is much much longer than the timescale for using capacitors or inductors for merely stepping up / down the voltage.

for example an ideal inverter drawing 10 kW DC and delivering 10 kW AC at 50Hz line frequency will by definition require an energy store of 10 kW / 2 50Hz = 100 J,

square waves would also work, but would still require 2 outlets, and would require the downstream equipment to tolerate it.
Is there any good book that provides an overview and reasoning behind all those concepts in this timeline?

In london commuter trains are over crowded and they spend millions (billions?) every year on upgrading and it costs me about £900 a month to use these trains.

If governments incentivised companies to encourage remote work, this money would be unnecessary as many people wouldn't commute any more - saving money for everyone, saving the environment and allowing people to have a home life and see their kids/partner etc.

Remote working is a massive win-win for everyone, I wish the government realised this.
I guess I am your boogeyman: I eat meat regularly, have investments, grew up and live in the middle of a western society.

By default I'm inclined to stop doing exactly zero of those, and by saying "you're at fault no matter what you do or don't do" you've just removed the sole remaining incentive for me to stop doing it: being able to say "it's not my fault". If I'm to blame no matter what I do, I might as well enjoy it and let the other suckers do the sacrifices for no gain that I'm unwilling to make, completely guilt-free.
