In general any such linear differential equation

f'(t) = M f(t)

can be solved as follows

f(t) = e^Mt f(0)

where M is a matrix and f(0) is a vector, and the matrix exponential is defined using the Taylor series of e^x.

Something like f''(t) = -f(t) can be split up as follows:

f(t) = h'(t)
h'(t) = -f(t)

which corresponds to the matrix

M = [[ 0 1]
[-1 0]]

which not coincidentally is a matrix representation of 'i' (it satisfies M^2 = -I), so e^Mt basically generates the same values as e^it (except as 2d vectors instead of complex numbers). Since the above is also the differential equation for constant rotation in the 2D plane this is another way of deriving the relation between the complex exponential and the trigonometric functions.
I have been to a few financial advisors and still use one. The problem is I lack faith in all of our current financial systems and the "solid" advice of investing in mutual funds, indexes and property seem to be long-term speculation these days, not investment.
Just because society thinks that a phenomenon is real, doesn't make it real. See: flat earthers, other types of conspiracy circles, organized religion.

I'm not saying that 'cancel culture' is something else, because it isn't anything at all. What people refer to when they say 'cancel culture' is the normal functioning of society and/or the market in response to events, just in response to events they don't have a problem with. Then they paint it as a 'woke conspiracy' to silence free speech.

If someone loses their job for harassment or espousing problematic views, that's a workplace doing its job.

If a popular figure loses fans or affiliations because of their past actions, that's public opinion at work.

If a company chooses not to publish a book, or a group of people boycott a brand, that's just the free market at work.

The only instances I see where certain people cry 'cancel culture, boooo' is when someone faces consequences for doing something the overall public finds shitty (like being openly racist or a sexual abuser), but the group crying 'cancel culture' does not particularly care. You don't see the same people complaining that Kaepernick was 'cancelled'. He similarly faced consequences for what he did, but no such outcry. I wonder why, maybe perhaps because it is just one of many alt-right forms of newspeak used to manipulate its followers and stir up fearmongering, hatred, and division? No, that would be far too logical. Ditto for 'wokeism'.
In the beginning, but now both sides see them as the enemy of the people. One side thinks they censor too much and the other thinks not enough. So YouTube is now caught in a political game of trying to appease whichever party is in power lest they get regulated. Hence why Trump stayed on Twitter until he was out of office.
"External headphones" should be a headphones icon, not a computer icon, is my complaint, to be explicit. It used to be correct in a previous version of macOS but regressed at some point.
Easy to find "bad tweets", easy to immediately publicize the "bad tweets" to the entire planet almost instantly, easy to have it trusted that the bad thing was said as the twitter timestamp exists and a bunch of trusted people talking about a screenshot if you delete it confirms it's genuine, not to mention most people don't use twitter imaging themselves giving a rehearsed speech in a public square, merely as a way to share their amusing thoughts to the planet for some immediate validation, the dynamic is pretty different.
Great! Time to bring this ideological principles to the US.

I'm not sure, selecting data from cells was slow. There might be ways to get around it. I did all sorts of optimization, but looking back on it, I probably shouldn't have saved anything in cells.

Although there are some cases under oppressive regimes where black markets may be a moral good, on the whole enabling financial crimes is, in my value system, bad.

This is basically the side-effect of the rollback, and it really sucks. Now, they have to keep this wasteful design, and less tabs will _nicely_ fit into the bar. I don't think the initial design was great, but I like it more over this!
In a sense, if people don't stop bullshit, no one will stop it for them. The state can't and shouldn't (ideally) stop YouTube from removing what they don't want to host, but people should hold YouTube accountable. If people don't stop using YouTube to make a point to them that their arbitrary decisions are not ok with them, nothing will really stop them. With that being said, I'm always hopeful that people will eventually see that forcefully removing something from the conversation (aka banning it, like banning doctors talking their successful experiences with hydroxychloroquine very early because some kids at youtube believe that a political org like WHO is more credible than actual experienced doctors) won't eliminate it, it'll just make it grow in the shadows, allowing other scammers to make use of the situation. And the cycle continues.
It's all about latency and ergonomics for me.

I suppose that terminals like Gnome's [0] are slow or feel "jittery" (i.e. inconsistent latency) for example because everything needs to go through a separate terminal server process. Then, there is Desktop compositing in the way. There might even be latency added by GPU acceleration (handling double buffering badly vs naively sending pixel updates to the Display Server?). Then, vector fonts are just terrible for programming on normal [1] displays - either anti-aliased (mushy, eye-straining) or not (jagged-y).

Another issue is historically bad / incompatible VT-100 emulation. I don't know what it is and I'm not a fetishist for organically grown terminal cruft, but in any case I've always had the most trouble with Gnome and KDE (missing characters, wrong colors, wrong drawing positions) while xterm works just fine, only the occasional "tput reset" needed after dumping binary data.

[0] just talking experiences, I'm probably referring to something based on VTE? Don't use Gnome regularly.

[1] "normal" meaning sub-4k / ~100dpi, soon will have to be referred to as "older"
What I do

1. Bookmark instead of liking tweet if info is worth coming back to.

2. Retweet if I totally agree and want to share my view with my followers

3. Add people to different curated lists instead of following them.

Twitter has some excellent feed curation tools but not many people are aware about them.
I wonder if you would agree to the following equivalent:

Considering the posters background, they may have just not taken it into account.

One challenge with abuse on all these fronts is that there is a huge amount of grey area in all of them, and judgement that would need to be drawn on what is and is not abuse. Sometimes/often it is REALLY clear cut (yeah, someone doing munchausen by proxy on their kids, or beating them, or whatever is clearly abuse).

Other times, you'll find a lot of controversy. There was a lot of discussion recently about parents getting cut off from their kids because of rabid Trump support. Is that abuse? From whom? There have also been stories of parents cutting off their kids because of their strongly anti-Trump views during the election. Is that abuse? From whom?

Mental abuse can be incredibly subtle, and a key component of many abusers is their ability to convince others around them that they totally aren't abusing anyone and it's that OTHER PERSONS fault.

Made even worse by the fact that sometimes the person being painted as the abuser IS NOT the abuser, and it really IS the other persons fault!

Sexual abuse and physical abuse can at least be generally judged somewhat accurately from a third party witness/video perspective.
I think you're over-simplifying - land with water access today doesn't mean anything in ten years with continued climate change. Unless you have water rights (and even if you do), that water won't necessarily be present (or potable) in ten years, and your water rights likely won't matter either.
A fed-engineered recession is certainly not ideal.

But more broadly, I was talking about the tradeoffs of fighting inflation insofar as ordinary people are concerned.
Cloud computing feels like one area we have fantastic competition in, even if there are only 3 major players (with one or two smaller ones). Feature and price competition between AWS and Azure is fierce, and if you’re dumb enough to have any trust at all in Google as a supplier then there’s even GCP.

Wages haven't kept pace with productivity since the 70's, largely because of a lack of leverage by employees. Inequality and stagnation have been causing significant pressures, arguably causing the surge in populism in 2016. Why not let employees have leverage for a while?
The minute someone steps up to actually deal with the nuclear waste we have, we can talk about making more. While it's sat in rusting drums on the same sites that produced it, because no one will offer their back yard or their cash, making more is a non-starter.

It's about hours per tank/recharge. They run pretty much 24/7 during spring and authumn. Filling the tank takes a few minutes while recharging a battery takes hours.

Misinformation is a really dangerous concept. Sure, bad information certainly exists, but a lot of things throughout history have been labeled "misinformation" before it became confirmed information.
An assumption, but it seems to me and many others that they’ve been slowly moving to make macOS more touch interface friendly.

I’m typically anti-touch screen on laptops as it drives the price up for a feature I personally almost never use, but there’s so many use cases particularly for a large portion of Apple’s user base working with digital media.

Aside: A Lenovo Yoga -like MacBook would be cool, although I do like the Touch Bar for quickly moving around in media I’m listening to in the background (but I don’t think that’s enough to justify it).
Yes. It’s time effective. Unlike criminal psychology where you build comfort, rapport, etc over hours.
Improving efficiency doesn't address the problem at all. If you only improve efficiency then consumption grows to negate any gains.

Oh, I imagined a much smaller runway — of course longer ones could be more than good from this aspect.
I don't think that is as true as you make it sound. I have managed on-prem and cloud infrastructure and am much more confident that my cloud servers are secure because a whole lot of stuff is done by the provider who know a lot more than me between them.

Even on a really simple on-prem scenario, you have switches to configure, vlans to setup, hardware drivers, a gazillion updates to make all the time and a tonne of employees making it all very difficult. The fact I can see it physically doesn't realy help me that much.
That was a very helpful distinction, thanks!

You can't have your cake and eat it too. Either Youtube needs to stop censoring videos or it needs to go through every single video it has and that gets uploaded
> While there are many many factors affecting obesity, I am still convinced that the most significant factor is that people are basically delusional about how much they actually need to eat and how much energy is actually in various foods. I could be wrong, but I've seen no rigorously done science that convinces me otherwise yet.

Why do you think that people become delusional or have become increasingly delusional in the last 40 to 50 years?

I'm pretty convinced that things like adenovirus 36 infection, phthalate exposure (especially in utero and as a young child) are obesogenic. I do think you're right that people are probably eating larger portions than in the 80's and often eating more calories, but I wouldn't be surprised is a large part of the reason why was because of obesogenic compounds and diseases.

Another reason I find this easy to believe is research on body weight homeostasis is pretty convincing. The leptin system is pretty strong at getting (some) people to eat less after eating more than usual one day and getting them to eat more after eating less than usual. There is also convincing research on what researchers call the gravitostat which, independent of leptin, alters hunger through weight-dependent signals from osteocytes in the large bones of the body.
This applies to a critical infrastructure one of national security.

GDPR is about privacy.
> Email is an entire ecosystem, SMTP is only a protocol.

Yeah, but it's a protocol for transferring email. As I noted with "you have to be very careful or have a lot of control over the receiving server to ensure you actually get delivery", you can amstract most of the mail system out as long as you ensure you are running the server they deliver to, but you would also need to rely on them making sure their outgoing server is good for this, which probably means dedicating it to this and not running any real mail through it (so you avoid outgoing company email filters, etc). At that point, both sides are running specific bespoke mail servers, which cuts down on the usefulness of the solution because of how much setup and administration it requires.

It used to be nobody ran incoming and outgoing filtering on email, so it was a robust channel for communication with retries, and notifications for failed delivery, etc. These days it's not exactly that because of all the spam mitigations and company compliance and risk mitigations that might be in place, etc. In fact, just setting up a new mail server and attempting to send to microsoft (live/hotmail), yahoo or gmail is extremely hard, because they have a high bar for acceptance, and large swaths of the easily obtained IP space have already been blacklisted from prior spam use so you start at a bad reputation and have to work to get it to a level you've even be allowed to talk to other by working with all the third party (and first party) blacklist maintaining entities.

I was more interested in latency of a strict serializability RSM like TigerBeetle.

I was thinking that maybe my use case is maybe something which should not be solved in the ledger directly, but merely the ledger should offer an API to fulfill transactions in the ledger. And the Api consumer has to provide an idempotency key to perform the transaction .
But then again I would assume that the ledger would have to provide an endpoint what the current balance is (the sum over all transactions). And when the api consumer makes a decision depending on KYC and current balance, whether to try to record a transaction on the ledger, in the meantime the balance could have changed.
So maybe one could send an idempotency key and the balance which was used to decide whether to fulfil the transaction.
Or a more generic version: an api consumer could send an idempotency key and a smart contract compute kernel on a transaction request. And the smart contract gets evaluated on the fly with the live data inside the ledger.

I smell like I am inventing a database and SQL here. ;)

Regarding: “ KYC would then be required before customer A can receive any more gifts ”

Where would the validation live? Inside the ledger as a contract per customer across their accounts?
When customer B tries to send money to customer A and A fails: what will customer B see? An immediate error or an asynchronous message
Can you show that source. I don't see one.
Losing control is what big social wants. The more they are regulated, the more intimate they are with the government, the safer and more entrenched their status. They already enjoy network effects and lock-in of their users; more rules widen the moat around the established players who got huge in the early unregulated days.
Those profits incentivize them to keep spam off their networks. The only incentive US Gov entities have is keeping their contracts alive and the money flowing in without ever needing to turn a profit.
I've really had enough of the minimalist, whitespace-everywhere trend.

I've been turning off most notifications, because since the controls were hidden, they're basically useless noise that just hides useful controls.

I know many designer-types want to get rid of the URL bar, but either butch up and fucking do it, or leave it as a useful tool. Quit shrinking it, overloading use, making it jump around another otherwise trying to make people not want to use it.

Iphone screens waste a ton of real estate, and (at least to my eye), it isn't even pretty, it frequently just looks unfinished, like the designer gave up on the job.

And so on.
I understand the motivation behind allowing users to lock replies, but you don't need Twitter for that type of content. Twitter sucks for just about anything other than interaction.
On the other hand, at least AWS, Azure etc. all have a vested interest in doing things well and securely. At a bank, most employees know nothing and care nothing about the HW and SW systems, they just use and abuse them.
"History is crazier than fiction"

This year I read/listened to 30 nonfiction books in philosophy, History, and science. It's been extremely enjoyable and rewarding.

My best advice is to put down bad books after 20 or 30 pages.
Resources aren't dwindling.

You could fit the entire population of Earth in a space the size of Texas with the equivalent population density of NYC. To support all of those people, the Earth has more than enough nuclear fuel in the oceans for thousands of years. Water is not a problem either when you have oceans and unlimited amount of energy, and with water and limitless energy it's not that hard to grow enough food to feed everyone (Hydroponics, gene editing, artificial meat, etc).

Perhaps in a thousand years we will run into some sort of natural limit, but by then I highly doubt humans will be a single planet species.

I think you're misunderstanding what I was saying. I do all the normal things for investing/retirement. If nothing in the world changes I will retire comfortably and early.

My concern is that none of those things will matter in 30 years. Dumping money into 401ks/markets/property used to be sound investment advice. Today they feel more like speculation. Even holding USD/bonds is a gamble. I'm not talking about traditional risk tolerance like large/small cap or foreign markets.

I did a vc company; my next one is 100% going to be smaller and bootstrapped if at any way possible. I definitely think it's the way to go for founders and tends to lead to better outcomes.

That said, I don't think most saas -- particularly midmarket or enterprise targeting -- can be bootstrapped. You just require too much engineering (ie eng salaries) in the first couple years to self-fund.
My biggest issue with their design was the horrible flow of clicking on someone's profile pic from a tweet that has a Fleet up, would pull up the Fleet instead of their profile

Certainly it is true that speech existed before the Twitter and the iPhone, and continues to today.

I (theoretically) could start my own newspaper and spread my opinion around, or go house to house and tell people there will be a meeting on a specific topic. With enough work and funds, I may be able to air my own television or radio station. I could do a letter writing campaign and spam everyone in a specific area code. I could scrawl graffiti on buildings to try to spread word for my cause.

All of these are good things, but it seems silly to me to be allowed to speak, but not be allowed to speak where people are listening.

And, I fear, all of these could be negated, too.

Imagine, for example:

- you are free to speak, but your newspaper is bad for the environment and must not be allowed (while others newspapers serve the public interest and are fine)

- you are allowed to transmit your TV or Radio program, but your license will be revoked if you talk about certain subjects.

- you can paint messages all you like, so long as they are inside your house

- you standing in the public square on your soapbox violates my safe space and must be disallowed

- you can speak freely, but only inside your own head (or far away from civilization), for your every word is being tracked and you'll be cut off from the economy if you don't say the right things

Fortunately, I don't think we're very far towards any of those dystopian ideas.

Truly, Twitter is not required to let me tweet, nor is YouTube mandated to let me post a video, but given the monopoly on attention they have within their spheres, if I can't speak there, my ability to speak freely has definitely been curtailed.
