For reference, the University of Illinois CS department, which has a significant number of international students, is having synchronous online lectures for 95% of the courses offered this semester. If you were in India/China, you would be watching 3am lectures, taking exams in the middle of the night, etc.
As a founder, I often have moments where I feel doubts and other overwhelming sensations.

This post is an ongoing collection of actionable tactics that I have curated from both my own personal experience and conversations with many others.

I will keep updating and adding to it. Any suggestions from the community are welcomed! :)

Hope this can serve as a quick reference for others too, the next time you feel overwhelmed.

This shit is hard. And you are not alone.
Sidenote: around half/a third of the article is on how to deal with Google IAM Auth. This is one of the things that puts me back the most from the modern Big Cloud and keeps me on Heroku, that it's such a behemoth of services and combination that you need such a complex setup for a very "simple" tool.

I like/prefer it a lot when you can simply put up a script, press 3 buttons and voila you have a fully working url. Even Google used to do that, I've built two libraries around Google's services, npm's `translate`[1] and `drive-db`[2], the former I no longer test on Google Translate even though it's supposed to be supported and the later it's using a more obscure plain JSON API to avoid Google Auth.

Their prose description of a bloom filter firstly has a significant flaw, and secondly falls victim to what I believe is a fallacy in many discussions about bloom filters.

The flaw is that they do not specify that the size of the bit array should be a prime number. This omission alone is astounding. To be fair, they state that they assume the bits from the hash functions are randomly distributed over the bit vector, so with this assumption they skate past this issue even though they have apparently missed that crucial detail of part of how it is accomplished. One wonders if they were unaware.

The fallacy imho, but this is where I depart from the community, thus imho, so take me with a grain of salt if you wish, is that you don’t need multiple independent hash functions. You just need multiple inputs. For example instead of hashing the word “salad” three times, just hash the tokens salad1, salad2, and salad3. If your hash function is worth its salt (npi) then you will be just fine.
It seems to me that reasoning is backwards. People agree to come together in society because the believe that doing so will allow their needs to be met. If their needs are not being met but they still go along with society, then it is likely because of the threat of violence if they do not.

For example, I recognize someone else's home as private property because I want my own home to be recognized as private property. However, if a society's economy is such that I cannot afford a house then the only motivation for me to respect someone else's home as private property is because society threatens to throw me in jail if I don't.
Out of curiosity, why are you running 2 k8s nodes on a single physical machine? Why not just run k8s on the physical machine? K8s should be able to manage all the processes correctly for you, and in addition you won't have the resource overheads of 2 VMs.

The only reason I can see having a VM as an abstraction layer is if your hypervisor runs in a cluster and it's able to move volumes across nodes, but even then, it feels like having a single VM running on the nodes that take up the full physical resources makes more sense.
It’s trivial to tell whether it’s working with some ordinary surveys and research.

No “megacorps” have done anything to make it impossible.
Criminals also profit from legitimate businesses. This comment is irrelevant.
You're correct, I was speaking somewhat abstractly, and only meant to include the smaller subset of the drug market that has a large amount of violence associated with it.
Ah the whataboutism is strong here. The point is, life is inherently dangerous. We make laws to punish people for making it more dangerous. People have had massive overdoses of LSD [see Wikipedia entry for LSD], several thousand times the standard party dose, and gone on to lead normal lives. All the arguments you make are exactly the same as arguments against alcohol, but LSD is actually much safer.
Yes and yes. This is what happens with corruption. The degradation of trust and civility is the point. The more it happens, the more civil disobedience happens, that too is inevitable. And this is known in advance, and will be what results in a demand for the police to use even more force to restore order.

Order is code for two things: compliance and nostalgia. Not trust or civility.

What you have recommended will tend to stabilize the covariance matrix, but not for the reason you have given. If numerical stability is an issue you encounter, I would caution against using it. Try [1] instead.

You imply that any symmetric matrix is positive semi-definite. Take an orthogonal matrix U and a diagonal matrix D with one or more negative values.

P = U * D * U.T is symmetric but not positive semi-definite.

For example, if D[0,0] = -1 then U[:, 0].T * P * U[:,0] = -1.

This is the core value of any team. Full stop. In fact, if you don't have collaboration, you don't have a team. You have a group.
“Black lives matter” is not an organization. It’s a simple statement that affirms that black lives should matter as much as white lives do. People say it today because data clearly show that in our society today, they don’t.

Mitt Romney says “black lives matter”... do you think he is an insidious Marxist? (For those not familiar with Romney, he got rich running a hedge fund and ran for president as a Republican.)

Yes there are a few people who are taking the phrase and adding in their own economic politics. Framing the entire movement based on those few people is the sort of bad-faith argument I’m complaining about above.
I agree with all of what you’re saying, but the comment I reply to says it “harms noone.” I am saying it does harm people.

To be frank, I have taken a decent amount of LSD in teenage years and suffer permanent effects from it (all mental stuff like anxiety and paranoia). Granted some of it was probably made in someone’s garage (legal stuff could have some sort of standards). But still, LSD is dangerous and point being it has potential to make people do things without cause for concern, and cause damage to others. It also lasts easily 8-24 hours depending on dosage.

Another point: if LSD was legal, then it would be legal for a cult to use it in rituals and as a way to manipulate individuals. Think Charles Manson—that’s a lot more dangerous than run-of-the-mill narcotics.
Genuine question: what's the benefit of having 2 nodes per physical machine, vs having a bigger node on each machine?
Thank you for the suggestion it looks promising!
This is something I've wanted for years, for numerous uses like collaboration, Method of loci, and documentation. Overlaying our built-in spatial awareness with focused data is an area of information architecture with a lot of untapped potential.

there is also this which allows multiple windows within unity (there's a demo you can try): https://zenfulcrum.com/browser
Sure, but desktop hardware is also more likely to fail quicker as they're not designed to be used like servers. So there's a trade off.
If only part of your “application” has more load than others what do you suggest?

That instead of being able to granular take part of the application that had a larger load, and run it on a Firecracker micro VM (the underlying VM for lambda and Fargate) with 256MB RAM and 1 core, we add enough VMs to scale a monolithic app - even the parts that don’t need it on a full scale VM with 8GB RAM and four cores?

We did actually have to do something similar for a legacy Windows app. We scaled the entire process up based on the number of messages in the queue. It was extremely wasteful. It required at least a 4GB/2 CPU VM compared.

>> IMO, yes, because there is nothing holding the country together besides the perception that the US constitution protects & ensures our freedom.

There are many things that "hold a country together" - some of them are known (here we have two examples), and others are unknown.

> it is an illusory experience that has some impact on the user. It isn't any arbiter of truth or knowledge.

It is surely illusory to a very large degree, but "what it is", really, is far beyond mankind's ability to judge such things.

Meth and crack are both cheaper than coke, which results in class/socioeconomic effects in who uses them as well as how they're portrayed in media and handled by government.
Did the same thing when I was 25 (1.5 years ago). A few things helped make this decision:
- I visited the US a lot of times (even stayed 3+ months) before finally moving. You could find ways like these to test the waters before jumping ship.
- Clarifying why I want to do this in the first place (is it FOMO or is it because it will help professionally/personality wise)

The main things that you have to watch out is the loneliness, you are basically leaving your social circles and family behind.
This would require someone willing to enforce the GDPR. So far the various data protection agencies have been very lazy.
Sounds like he really believes in the power of fasting. It’s possible for him to commercialize something that works, and to keep doing scientific research to build on that foundation. It doesn’t have to be shady.
Had a Russian friend who was horrified I called them “BB guns.” He insisted they are “pneumatic rifles” and treated them the same as any other firearm.
I don't know. We haven't probed what zero-G manufacturing might be capable of. One of the amazing properties of a near-perfect vacuum is that there are near zero contaminants. Being able to more accurately control reactions might yield breakthroughs in room-temp superconductors or metallurgy. I could imagine there's some low-hanging fruit too since we're just starting to probe the possibilities.

That all said, it's therefor possible that the things that make these supposed craft unique might be defined by their requirement to have been manufactured in a zero-G vacuum.
The Economist’s Democracy Index as of 2019 rates favorably enough most East Asian democracies that have been handling COVID-19 well so far; some of them score higher than the US or half of European countries.

It doesn’t seem like “capable of containing a highly infectious disease” and “oppressive” go hand in hand.
I disagree with the failure claims except for lack of adoption.

How can unreliable distance measurements be an issue? Actual viral spread over distance is a much, much bigger uncertainty. Even improving distance measurements to the nanometer wouldn't make much of a difference considering transmission prediction. Sometimes the virus bridges tens of meters, other times it fails to make landfall in a prolonged skin on skin situation.

Measuring impact is a simple polling research problem: if you want to know this kind of thing (and I think you should) you need to accompany your PCR tests with a tiny little questionnaire collecting data about why the test was done. Failure to collect that data is entirely unrelated to the app.
> so actual Flutter is just Google NIH syndrome…

So true.

If Google can't control it, they build a competitor. If Google can't figure it out, or if it is not 100% what they need, they will build a competitor.

This has caused tons of problems for both the industry and consumers. For example, Android updates would be much less of a mess if Google had used linus' LTS kernel...

It's certainly less of a problem. But people are notoriously lazy, and a service where you could switch savings accounts in the same way as a current account would make it more likely. It's the cost / benefit trade-off, so if differences in interest rates are very small you need to make it even easier for people to switch.

For example, I'm being paid 0.3% on a current-acount-linked savings account. If I could switch that to NS&I (1%) more simply than I can currently, I would. But given the relatively low amount in the account, and how much I feel my time is worth, it just doesn't feel worth it to me. Yeah, I'm lazy. But so are lots of other people, and it would change the dynamics of the savings account market if it was easy enough to make me want to switch.
Hey, if you ever wanted to come on my podcast to talk about your tech stack (how it was developed, deployed, lessons learned, etc.) I'd love to have you on.

There's a few Phoenix episodes out currently, but none are using Live View yet. It would be really fun to talk about how someone is using it in production.

If those openings stay open for a long time, perhaps. In the short term it says more about how many people are looking vs how many people they've evaluated/interviewed/hired/rejected.
> I disagree. If you take [action], and it was a necessary and sufficient condition for [consequence],

That's exactly the thing though isn't it. Marijuana is (was) illegal, and has VERY LITTLE amount of violent crime related with its market. Making something illegal isn't enough to induce violence alone. So the [action] of (making drugs illegal) itself alone isn't enough to make [consequence] of (additional violence) to be a certainty.

Or, consider the simple case. I insult you, you punch me. You clearly wouldn't have punched me if I didn't insult you. Who's at fault here?
> Remember, the term "fake news" was conjured by left-wing media in response to Trump's election victory, referring to up and coming media companies which were eating away at their numbers

This is completely untrue and a deliberate reframing of Donald Trump's actions in the most benevolent possible light.

"Fake news" referred to actual fake news. Like 5G causes coronavirus, Hillary Clinton runs a secret pedophile ring and literally kills people fake news.

Trump repurposed it to refer to any news item that he disagrees with or that casts him in a negative light. (And in fairness, some actual fake news falls under this category as well, but the proportions are small enough to make this useless as a differentiator.)

He labels CNN "fake news" for calling him out on easily verifiable lies. At this point, anyone who doesn't acknowledge that he often conveys falsehoods to his audience is being purposefully obtuse - I have more respect for the people that admit this but believe it is a justified means to what they see as a desirable end.

> We need less state, not more.

I assume this means you are opposed to the untrained and unidentifiable federal troops occupying US cities in direct contradiction of the desires of local officials, right?
You think a ratings system would deter companies from misbehaving?

The credit rating agencies have some of the lowest consumer confidence scores in the entire country, and yet Equifax suffered no consequences from its massive breach a few years ago.

>> This man made a product that others willingly wanted for themselves. There are no victims here

People may think LSD or cocaine is all well and good, but there are far more dangerous substances out there. Things like Carfentanil need to be regulated. So too all the so-called "date rape" drugs. Just because some guy wants a powerful, tasteless, anesthetic that can be readily dissolved in water doesn't mean we should let him have it. Even if it has personal uses, the danger of such substances means they need controls.
Isn’t that crazy if it’s true?

Yeah we had to self-confine for super long and it exacerbated all our societal problems, but at least it made the US government admit there were aliens!
There's also the externality of increased load on emergency services and hospitals.
There are services (google Max my Interest, this is not a product plug) that will allow you to automatically shuffle money between many high-yield online savings accounts. They'll make sure that your money stays in the highest-yielding account, but remains under the FDIC insurance limits.
That is largely a luck and legacy thing. inReach is an acquisition by Garmin. They haven’t made significant changes to hardware and software besides rebranding things and adding integration to their newer units, e.g. I can trigger SOS from my watch.

In fact the billing is completely separate.
For gasoline there are federal, state, and local taxes. Also, each jurisdiction needs gasoline to be made differently than in other areas. Gasoline is a processed product, and it differs from crude.
Well as enterprise theme would have some of these characteristics:

I thought a bit about this argument here, and I just want to sum it up, so we can understand where this landed.

The sum of the final argument is “I believe that you should do whatever the gunman says, so much so that I don’t care if they kill you”, directed at a commenter here.
I mean, they are detecting them, we’re talking about pilots detecting them. They just don’t know what they are.
I don’t think you would waste your years there, but I can say that I really started to appreciate the European model when I had children. There is no parental leave in the US and you’re likely to spend more time working/commuting by comparison.

Having had a child in Denmark, I really have no fucking clue how Americans handle it.

It's an open source ecosystem. This piece sounds important to you. Have you considered contributing?

It sounds like you've identified a niche that isn't filled -- perhaps you could "corner the market" taking advantage of the SkyWater / Google offering. A risc-v microcontroller with the bitmanip extensions would be very cool, and its existence could prompt compilers to start targeting it. Go for it!
The protesters are there on their own initiative to express their own opinion. They should not have to stop because a few bad actors show up and try to hide in them.

It would be like saying no one should go to the market because a few pickpockets use the big crowd to hide in.

People don’t go to the market to hide pickpockets. And protesters don’t protest to hide brick-throwers.

I would have loved it if the Zuckerberg endowment was an annual donation to the hospital's bottom line. Then we'll see whether the doctors and nurses are willing to put their money where their mouths are, and make some real responsible choices about which is their priority.

San Francisco supervisors, on the other hand, are complete political morons. They can spout pure bullshit and not face any consequences from the voters and electoral system designed to incentivize such idiocy.
> Still, I think the age has something to do with it.

No, it's the externalities. When you fly you don't just put yourself at risk, you put others at risk as well. Roads are designed to isolate faster-moving vehicles from people and property so the people who die are mostly the occupants of the vehicles and there is not much collateral damage. But it's not possible to isolate air traffic this way. So it's not just the occupants of aircraft who die, it's people sitting in their living rooms watching TV when a plane suddenly comes crashing through their roof.

Also, the limiting factor on air travel is not technology, it's takeoff and landing space. Even VTOL aircraft need a lot more room to takeoff and land than a car does because there's a blast zone.
Yes, those violent LSD trafficking organizations.

The rhetoric is like straight out of the '80s and is not a "valid argument."
The pneumatic description can be accurate. But I'm not aware of a BB gun with rifling. My understanding is that BBs, being spherical, don't work well with rifling.
Manufacturing a substance harms no one. Distributing a substance to willing participants harms no one. possession harms no one. Use may harm the willing participant but I would argue for the freedom of that participant to make that choice.

Hence the mention of some pretty clear historic problems we have to address. I also don’t fully support some of our recent wars, and I don’t pretend to say we’re perfect. We’ve pretty clearly done some bad things even quite recently.

What I love about this country is that we talk about it, we struggle with it, we do so publicly, and eventually we try to do the right thing. Our ideals are pretty good, just really hard to live up to, and the real world is complicated. We support dictators abroad, we have a racially unequal (though improving, albeit too slowly) society, there are no saints among great nations.

The point is in trying to live up to the ideals. If we compare to other great powers, I think we do better than most historically. As long as we keep moving toward universal human rights and freedom, however imperfectly, I’m on board.
