The existence of several attachment disorders, where insecure parenting styles and resulting poorly developed attachment has been irrefutably shown to be the cause of the disorder, refutes any claims that "the relationship with early caregivers might not matter at all"

For an extreme result of poorly developed attachment see https://en.m.wikipedia.org/wiki/Reactive_attachment_disorder

Several comments here are dismissive of attachment theory and the importance of proper development of attachment. I don't really know why but it might be the unfortunate existence of the pseudoscientific "attachment therapy" which has nothing to do with what the article is about:

I don't think the author is advocating that founders take on a ton of of personal debt, just that historically it was a filtering function that is now absent. I would imagine that this filter function can be replaced by something else that does not also weed out people without any safety net.

The point is valid - startups are a risk, and so if all the risk is removed, it will increase the number of people who are coming to YC for status vs. coming because they believe in their idea.

As good at interviewing as the YC partners may be, interviewing is no substitute for the harsh reality and incentives imposed by taking a great risk.
"To complicate matters, numerous studies over the past few decades have reached what seems a counterintuitive conclusion: that all psychotherapies have roughly equal effects."

The article gives a number of possible explanations for this, but not the obvious one: that the effect of psycho-therapy right now might not be more than a placebo effect. I wonder why this could not be the case.
I am just going by my experiences but Alexander being a psychiatrist is literally the only thing I know about him from the last time I heard mention of him.

He mentions his job several times in his "goodbye" article. It is a big part of his online persona that he has deliberately put out there for his own reasons.

Yes, it is possible to emulate a quantum computer, and this is done quite often for research and to try out quantum programs.

The problem is it takes O(2^n) classical computer resources to emulate a general purpose n-qubit quantum computer. In other words, exponential time or size.

(We can simulate some larger quantum chemistry systems on a classical computer, but those aren't general purpose. The simulations are quite restricted in what they can measure, and there's still a significant practical size limit.)

So we can only emulate very small general purpose quantum computers or other quantum systems. For larger quantum computers, in principle those can be emulated too, except you would need an impossibly fast and large classical computer to do it. So we can't do so in practice.

This is actually the motivation for building real quantum computers of significant capacity.

If a real quantum computer can be built with a large number of high quality, fully coherent qubits, it will be able to do calculations that can't be emulated on any classical computer we can actually build and run, just because of the O(2^n) practical limit.

Right now, there are no quantum computers like that. There are some dubious marketing claims around, and there are also some genuine, but smaller, devices.

Because we can't even simulate a large quantum computer, we don't know for certain whether such a device can even be built in the physical world. The abstracted maths of quantum mechanics, which has proven to be extremely accurate and correct for everything it's been used on, says it can (subject to practical engineering details), but the physical world may have a subtle limitation which we can't detect in smaller systems, that only happens with larger quantum computers and prevents it from being possible. The maths itself might even have a subtle reason (such as stability or entropy) why the system cannot work, but no such reason is known at the moment. We can't "run" the maths to find out its behaviour on a large system, for the same reason we can't simulate a large quantum computer without a large quantum computer in the first place. We can only reason about it in the abstract.
This is outrageously misleading. To make a claim about the number of synapses between neurons based on MRI data is completely unwarranted. Voxel size (single volumetric pixel) in MRI is approximately 1mm, while synapse size is way less than a micron. You need resolution per pixel on the order of 10s of nanometers to identify synapses.

It's an algebra game.

Given a set of operations, can you get to state X?

Usually requires a lot of searching and/or expertise, however the solutions will break pretty easily depending on which shell you're using, etc. So doesn't really teach you anything aside from iterating over a set of all possible operation combinations.
Maybe the point of economic filtering is to only accept single young men, who can devote every waking moment to their startup without any concern for dependents and such. You can get great velocity from such a pool.

Myself, with family, mortgage, etc. I would never be able to achieve that kind of velocity if I were accepted to YC.

So, even if I had incredible ideas, as people around here keep saying, and PG makes clear in his Viaweb essay, it is not about the ideas but about execution.

Thus, the economic filtering for those who are unencumbered and thus can really execute on their idea or something that YC comes up with makes a lot of sense.
While this seems to work against several current techniques, there's no guarantee it will work against all of them. It also offers no guarantees against future developments, and anything you put on the public internet is likely to be retained forever. Because of this I'd consider it an interesting proof of concept, but not something anyone should use as a privacy tool. You could consider it in cases where you're forced to provide a picture, for instance my public transport card requires one.

I would think it's very difficult to study human attachment using effect sizes. The sheer diversity of attachments a human makes and the rate at which each attachment changes means you're almost certainly seeing some confounding effects. You could bin attachment into styles and levels but it's more like a continuous function and you can never be certain that your bin sizes are adequate to describe the whole variability of the system.

If the design is the code, then what is a bug? There is a separate model, whether written down or not, of what the code must do. That is the deaign.
Agreed. I would use it, unless it was made by Facebook, Amazon, Google or Apple.
Did it run on something that slow? I remember being amazed by the surprisingly decent performance on my Pentium-based PC but it was like a 233 or 266MHz chip if I recall.

Either way, it was great because I was a young guy without much disposable income and while my previous roommate had a Playstation, I lost access to it when we moved. I still had a handful of games and I could continue playing them on my janky PC.
Creators,

i love you thank you.
Twilio says the only modification done to the script was to check if the modification could be done. If the hackers modified the script so it would call their own servers to check for that, they now have a list of IP addresses and timestamps.
There are cases where you only have 1 instance of something, never 2 or more. Most developers use such things dailyu, like in JS you have the window object, most of the time you don't pass the window as a parameter in all your functions but in one project I worked it was a requirement to pass the document as a param in all functions that needed it. So the my opinion is that it depends, sometimes having a World,App,Window etc global helps more then it causes issues and is preferable to a solution that is pure that costs you more. FYI I use a functional style as much as possible, no side effects but sometimes pragmatism wins, in my current project I guarantee we won't change our database or upgrade the current framework to a new cooler one.
What are you talking about when looking at the distribution of outcomes? What are the outcomes?

The value of school for me was (in no particular order) learning how to learn, how to tackle large projects with difficult questions, how to work with other people, how to manage my time doing all of that, building a network of both people in my area and outside of my area, smoothly transitioning from childhood to adulthood, having freedom to explore and discover the things that truly interested me, and having a really good time doing all of that.

A huge part of the value of school came from staying on-campus in student dorms my first two years. Living with a large group of people expanded and enriched my social life tremendously. I loved being so close to the school and libraries and all the facilities. Its hard to know for sure but the social skills I gained are probably as valuable as the computer science education in creating the life I have now.

You can't design interventions for problems that you cannot see. Detection alone doesn't save lives, but it is a necessary step to the discovery of interventions that do.
I'd be willing to bet that a clear majority of the most successful startups from the past 20 years were founded by people who were otherwise independently financially stable.

It's very hard to focus on building a successful business when the cost of failure is potentially life-ruining.

AWS's shared responsibility model is clear. AWS is responsible for security of the cloud. The customer is responsible for the security in the cloud (i.e. the customer's resources). By the way, enterprise support customers do get access to well-architected reviews by AWS.

If you ask for help from AWS, AWS will provide it. It may not be free, but it's available.

Even if AWS were to start proactively auditing customer setups, how in the world is AWS supposed to know what a customer's usecase is? Nevermind the fact it's a breach of the customer's privacy to just go rooting around in the customer's account without permission.

But let's assume AWS is going to take responsibility for customers' configuration decisions and violate customers' privacy by proactively auditing their accounts. Would AWS auditing Twilio's configuration here work?

The default is for S3 buckets to be private. The customer has to take specific, affirmative steps to give s3 buckets public access. You really have to jump through hoops to make a bucket public accessible.

Since the Twilio chose to make their bucket public, AWS auditing Twilio's setup wouldn't be helpful. AWS would just assume the Twilio knows what they're doing. How is AWS supposed to know there is a misconfiguration? Because Twilio clearly decided to make their S3 bucket publicly available.
Hoffer certainly led an unusual life.

> I'd be very surprised to see an organization not use some sort of design doc before building things - the only thing that would be different is the scale and scope of them.

There are companies that use agile methodologies and eschew any kind of design documentation (they kneel at the altar of working code, and working code alone). I’ve seen teams just discuss things, get a few inputs and start writing (working) code and pass it through testing. The design process exists, but there’s no document or documents for anyone to refer to. There may be high level architectural documents, but not what many people understand as “design documents”.
Yes. They invest seed money. They help you turn an idea into a series A. Maybe it has lost it's soul because the round structures are so much looser, or the greater availability of angel money.

Seed money used to be a godsend because you had a good idea that wasn't at a scale enough to interest traditional VC and you didn't know an angel. YC was particularly great because it had the emphasis on the network and the larger number of investments allowed it to distribute risk across the class.

They purpose was not to build a company or make a good living, it allowed you to create a company you wouldn't have been able to, otherwise. I agree with the gp post, the goal is not to fund a sustainable company, it's to get one off the ground.

No, they're arguing that since Microsoft has a monopoly on office productivity software[0], adding new features to it that are in direction competition with other products is anti-competitive behaviour.

And they are right about that. Microsoft has been repeatedly convicted for this behaviour (Windows Desktop -> Internet Explorer, and Windows Desktop -> Windows Media Player). Trying to argue otherwise would, IMNSHO, be silly. The only valid question remains, does Slack's offering itself (corporate IM) fall under the office productivity umbrella or not?

As individuals we each have our specific needs, wants, and preferences in activities and hobbies. We also vary in how we react to events and behave in situations.

> Jermaine didn’t wait for something to be happy. He appreciated what he had, but wanted more in the future because he believes he could help people. He didn’t want more out of vanity.

Jermaine had the ability to realize where his emotions and perspective stemmed from. Your examples, Bill and Robin, did not have this ability and were both held back by some strong force (i.e. insecurity and ignorance).

If all people had the ability to look within and reflect on their thoughts, feelings, and choices—to be introspective—then more people would be like Jermaine.

However, I don't believe that people can suddenly choose to act like Jermaine and choose both ambition and happiness.

There is a disconnection between people and their emotions which impedes their ability to know what they truly need and want to do with their lives.
You might be able to put something together using Raspup or Ultibo. IIRC, both should be able to run on all Pi models. Both are pretty lightweight, simple, and they could be a good base for building what you are looking for.

Raspup is a Puppy Linux for Raspberry Pi. It uses Raspbian Buster as base. I haven't messed with I2C on my Pi, but if there are any userspace tools in Raspbian Buster's repo then you can use them on Raspup. The working upgrade path is the biggest annoyance here. Package management on Puppy in general is a pain for anything but simple install and removal. It seems like the Puppy community either doesn't upgrade or upgrades by installing the next Puppy version (which is usually fast).

Ultibo is not Linux but a Free Pascal kernel that doesn't implement a complete OS. It is for using a Raspberry Pi board more like a microcontroller, but you can use it as a base for anything. For example, someone made a Z80 CP/M emulator that runs pretty fast. Besides the Free Pascal library, the tools here are pretty much what you write. This is probably the simplest option for a Pi that may be alright if you don't plan on using the full functionality of a Linux machine or you want to avoid the Linux kernel scheduler.
Proof of life outside earth would be the coolest
It is way too easy to screw up S3 bucket permissions. I caught it once when a coworker told me they setup a bucket for testing that allowed employees to upload, I checked the permissions and it allowed the world to upload.

It would be much harder make that mistake with Google Cloud Storage, at least in the web console. GCS also supports disabling bucket ACLs permanently at bucket creation time, and that is the option they recommend[1].

AWS does scan and alert for some public bucket issues. But with all the public S3 issues, I think it is clear there needs to be more prominent warnings in the AWS console, the command line, and with tools like Terraform.

MRI can’t do imaging at synapse level, even high powered on small animals. This has nothing to do with connectivity between neurons. It is more like they do correlations on correlations, and find mammals share some basic connection pattern (by correlation measurements). It might surprise those who don’t believe in evolution
