tetrahedr0n··on AMD CEO sees chips from TSMC's US plant costing 5%-20% more
Is it ridiculous to expect an economy, such as the US, to produce things of value?

The author of the post you are responding to has a valid point. Consumption alone isn't sustainable.

tetrahedr0n··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
A controversial statement to some, but IMO the US is a Corporatocracy more than a Federal Constitutional Republic. More "Modern Corporate Capitalism", less Free-market Capitalism.

Point being, some businesses _are_ more equal than others because they have the money to lobby lawmakers. In an actual free market, the banks should fail.

However, it seems to me that the situation with SVB is a Democratic Socialist move. Again, my opinion, but it seems rather progressive. In history, Democratic Socialist programs have produced, arguably, valuable programs for the US. Unfortunately, mentioning "Socialist" is usually the point in which many will stop listening.

In a more perfect world, I totally agree. But with American average savings so low and with the average level of financial literacy so low, expecting half of America to join the ranks of financial system watchmen is, IMHO, a tough hill to climb.

I'm sorry, I don't follow the logic here. Do you mind elaborating?

I see some correlation between SV remote working and COVID, but don't understand how mortgage backed securities play into this. Are you suggesting higher inflation on the way, lower property values, higher rates, and that it was intentional?

tetrahedr0n··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
I might be missing something, but not sure why this was downvoted.

Deposits <$250k are FDIC insured. One could say those accounts didn't evaluate the institution that held their funds and didn't really need to. But were they aware of FDIC limits? IMHO, they should have been and likely were.

Depositors >$250k are well aware of FDIC and the risk associated with money in their bank. They really should think about the banks they work with and understand their risk profiles.

Subjective, but I understood how FDIC worked when I opened my first bank account that was no where close to 250k. If it was greater, I would optimize my holdings across different institutions and instruments.

> Apple has 50 billion in reserves, do you think they can find 200 thousand banks to spread that around?

Good question and of course, that's not likely. But then 50B in reserves isn't something you keep in a bank account, it's something you have rolled into several different financial instruments with varying levels of available liquidity.

tetrahedr0n··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
Also, holding all of your fiat in a single bank or financial instrument is usually not a great idea. Diversification is important to any relatively stable financial position.

E.g: Fiat over $500k in a single institution is likely not earning as much as it could and runs the risk of loss of access to funds for X amount of time if the bank fails, until reimbursement happens. But $100k each in 2 different banks leaves you with $300k to invest however you see fit and still have enough liquidity to move quickly on opportunities.

tetrahedr0n··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
I believe that would be the FDIC, which is funded by banks (its deposit insurance), right?
tetrahedr0n··on Mind Your Own Business Act of 2021
True, it doesn't seem likely to apply to the government itself.

I'm not a lawyer, but my interpretation is that it may apply to credit bureaus and data brokers. As well, for better or worse, pretty directly affect FinTech.

But I digress, the implications of this bill could result in more unknown unknowns than I realize.

tetrahedr0n··on Show HN: Write 500 Words a Day
I love that you took action to make your idea a reality. That's a trait that not everyone shares, from my experience. Writing is a wonderful way to express yourself creatively.

I can relate. Essentially, it's a journal. I find journalling to be very healthy for my mind and have journaled online and offline for most of my adult life. Though, I must admit, I don't do it everyday. Personally, I find doing something artistic daily to be the most fulfilling. Whether drawing, writing, playing music, or whatever, it allows me to reap the benefits of exercising those creative muscles.

The part about writing a few pages when you wake up is a good idea, IMO. Not that it needs to be a daily structured routine, but what you experience sleeping is a unique experience that is worth writing down, occasionally. I've reflected on earlier journals I wrote when I woke up and have been surprised to read something I almost didn't recognize as my own.

tetrahedr0n··on RIP Good Times (2008)
> Free market: an economic system in which prices are determined by unrestricted competition between privately owned businesses.

Interesting concept, I wonder if it works.

tetrahedr0n··on Making the dislike count private across YouTube
Brilliant.

People will often watch something they dislike with more intensity than something they like. The number of dislikes isn't the reason they want to watch it, it's the idea the title or cover image brings to mind. And those ideas and images are curated by Google.

Take the number of dislikes out of visibility and you strip the noise away from the signal that makes them money; views.

And who knows, the user might end up watching something that they wouldn't normally due to dislikes and, surprise, they like it. More exposure, less echo chamber-like. Less potential influence over a viewer's opinion of the content.

tetrahedr0n··on Ohio Republicans close to imposing near-total ban on municipal broadband
Promise resolution tracking for political choices could be a useful tool. With each promise tracked you could produce a percent which could be displayed with the candidates picture and a brief synopsis of their "score". The contact information and a tool to initiate communication would all be available (even if the communication is just email), and you could even have the politicians join so that they could have like an intern respond to messages or something.

This has probably been done, right?

tetrahedr0n··on Lambda School lays off 65 employees
Lol, absolutely.

Austin may have been the right guy to start the company, but IMHO, he should've handed it off to someone with a background in education a long time ago.

tetrahedr0n··on Lambda School lays off 65 employees
Things might have changed since I finished the program, but their career services were effective for me.
tetrahedr0n··on Lambda School lays off 65 employees
I think the problem is that their part time outcomes were much smaller than full time. And it wasn't entirely an instructor or curriculum related problem.

You are correct that schools like this (secondary/trade, not ISA, necessarily) do well during economic downturns, historically.

tetrahedr0n··on Lambda School lays off 65 employees
My ISA with lambda is for $30k USD that I started paying after I landed a job. There is no additional tuition. Program is less than a year. That's significantly cheaper than any of the universities I could have gone to.

The trade off, in my mind, is that I didn't become a SWE in lambda. Engineering is far more broad than learning how to build a CRUD app. Since Lambda, my self appointed curriculum has been engineering fundamentals, design patters/language/etc. Knowing how to write a BST is a lot different than understanding the core concepts behind everyday algos.

tetrahedr0n··on Lambda School lays off 65 employees
I think this is correct, re: the Pareto principle.

I'm a Lambda grad (Full stack web, not DS) and at the end of the program, I was knowledgeable about a lot more than I understood; and that also includes being knowledgeable about a lot of my shortcomings that I was painfully unaware of before Lambda.

A year after Lambda working as a SWE and I am now finally starting to feel a sense of domain... I hesitate to call it expertise, so lets say domain 'comfort' when it comes to building and maintaining react or react-like FE applications and node BE apis. I've had a mentor at my company since I started and mentorship is necessary for anyone coming out of a bootcamp with no prior industry experience, IMO.

The expectations set within the bootcamp are reasonable, IMO. Instructors never made it seem like we were going to fully internalize everything we were being bombarded with. Practicing what you learn is crucial to turning any of the things taught into a skillset, and that is made very clear.

I imagine the outcomes are pretty good for those who get through the program, as well. They were great for me and most of my cohort peers that I keep in contact with. The ISA model, IMO, makes a lot of sense and I'd be surprised if Lambda couldn't make it work in the long run.

tetrahedr0n··on Letters from House members to cable providers [pdf]
I believe the OP's point was that those things (Agent orange, tobacco <> cancer, etc) which our society almost universally agree upon were once, themselves, targeted by dis/misinformation campaigns.

And that if we are to allow censorship, we are allowing the potential for disinformation campaigns.

IMO, the flaws in this argument are that it assumes a disinformation campaign is something the censor entity is controlling (specifically the US military, in the Agent Orange example). It also assumes disinformation is the only tactic available to a bad actor to manipulate the public.

To the spirit of the OP's point, though, I think we need to be wary of any corporation pledging to make the world a safer place by monitoring our communications.

Of course the situation is not binary; there are things that should be censored. I would like our law enforcement to use any tool at their disposal to stop human trafficking. Murder is not cool, AT&T should help LE look into those as well. Politician Y is trolling the internet with lies; we actually have a toolset for that and it's called journalism. Understanding that journalism/media is actually part of the problem here doesn't mean AT&T can do a better job.

tetrahedr0n··on Beej's Guide to Network Programming (1994-2020)
For the brief amount of time I was your student at Lambda, you made a huge impression. Beyond this tutorial, you're a gifted teacher and inspirational person. Much respect and love!

I'll read your future-brainwave-transmission tutorials, anytime, even if they run the risk of causing minor insanity!

tetrahedr0n··on Missing Covid-19 test data was caused by the ill-thought-out use of Excel
I agree.

Tools exist, for analysts and engineers (MS Access comes to mind for the analyst, python for the engineer), that would rectify the problem. And I think it's a fair assumption to say that those tools would be readily available.

Kinda sounds like a management issue, as well. No one ever said "hey you know XLS doesn't support all of this data"?

What a mess.

tetrahedr0n··on On the Use of a Life
Really interesting point of view. I have some opinions about your logic and I in no way am trying to attack you. I disagree... the irony is not lost on me, either.

Comparing:

- Reading the source code of HashMap vs reading the API.

to

- Reading HN comments vs source articles.

...is not a fair comparison, IMO. Well what is, then? Ok, glad you asked!

Reading HN comments vs source articles is more like:

- Reading the book vs reading the reviews on Amazon about the book.

Comments on an article are not the API docs to the article. Going with your analogy, the API docs of an article would be something like the spec for how a concept fits into a perspective of a topic (...this sounds so confusing...but, just work with me for a minute, please :D). Unlike something like HashMap, articles are almost always going to be less objective and more subjective. When something is subjective, you could think of it like everyone designs their own API docs; the protocol with which you interact with a concept can be designed by yourself.

The problem with not designing your own protocols (perspectives) for interacting with a concept is that you could be missing an arbitrary 3% of information or the information that your gleaned could be of a completely different taxonomy (or unforeseen perspective dependancies, maybe deps that you don't agree with) than what you would have designed if you had read the article.

This matters because when your perspective is guided by the perspectives of others, you miss out on a lot of opportunities to make connections across topics throughout time. Maybe the cryptographic inventions the author describe connect with another detail in an article about DIY satellite programming or some voting machine vulnerability that inspires you to do something bold (whatever, who knows, that's the point); changing the course of your life.

As a species, I think (super opinionated part) we will advance further if as many of us as possible are actively 'reading the books' and 'forming the opinions'. I don't think the amount of value someone can bring to the world is strictly correlated with their IQ. So everyone can bring value to a discussion or a body of work or whatever, if they think critically about it and develop their own opinions based on their own unique perspectives.

tetrahedr0n··on Can TikTok be banned from US based Android devices?
I think I can help provide some proof.

First - the article talks about the message delivery via push notification. The push notification is, essentially, a JSON object.

The relevant notification for push/delete would be something like:

  notificationType: 2
  docid {
    backendDocId: "com.zhiliaoapp.musically"
  }

Second - ADB itself, of course, provides a command for removal of an app. Only requirement would be permissions. If working direction with a console on target device, that command is going to look like this [1]:

  pm uninstall -k --user 0 [package name]

Third - Google playstore has the permissions required to read and write to the phones filesystem. I can't find this explicitly stated, but I'm sure someone else will link to some documentation showing this is true.

Fourth - Kinda makes everything else a moot point, google play apps are served by google clouds (the author mentions this as well), so even if google couldn't remove the app from the phone, it could essentially cut the cords to the APIs and render the app useless. [2]

2 - https://developer.android.com/guide/playcore/dynamic-deliver...

Final thoughts: The author touches on this, but I don't think anyone really knows the answer. Google can remove TikTok, but will they (they haven't yet, right? lol)?

EDIT: formatting and final thought

tetrahedr0n··on MoviePass CEO says the app tracks your location before and after movies
Rare is the problem that legislation actually solves.

And

People don't want to pay for apps with money, they "just want them". So they pay with their data. The problem here isn't with the transaction, the problem is people are in the dark with what they are actually paying with.

Companies are allowed to do this. Their TOS protects them.

tetrahedr0n··on MoviePass CEO says the app tracks your location before and after movies
Overall, MoviePass is a step forward for privacy advocates and a benefit to "netizens".

MoviePass just set the price for your data; an abstract possession that people are barely beginning to value as an actual possession of theirs. The going price for tracking your purchasing behaviors before and after attending a movie is the cost of however many movies you can see in a month minus $10.

Facebook paid with a social networking platform to connect you to an unimaginable number of people you probably wouldn't be connected with otherwise. For that, you gave them your history and your super-ego.

Google gave you a map, an email, a phone number, and a bunch of productivity tools. For that you gave them everything.

The value of your data is holding steady or going up, depending on your perspective.

Also, MoviePass took a step in the right direction towards disclosure of intent when their CEO opened his mouth about it. Their TOS is typical, but the CEO is more transparent than most. They should be the brave first company to make their intention transparent.

tetrahedr0n··on FBI Says Chinese Operatives Active at Scores of U.S. Universities
Hard to get through some of these statements:

> They have a long-term strategic objective to become a world power. > Director of National Intelligence Dan Coats

O RLY? Funny, last I checked, China was a world power. Shit, China rivals the US as a world power.

> Most Americans have not heard of all of these companies. > Sen. Mark Warner, a Virginia Democrat

Surprise surprise! Well, most American's haven't heard of Acxiom either. It's always surprising how much other people don't know, isn't it?

And, FWIW, I bet more people have heard about ZTE than half the organizations that contribute to Mark Warner's campaigns. New companies entering our markets from China have to play by the same rules our own companies do, how is this any different. If it is different, why? How does this matter in the discussion of Chinese intelligence gathering. More importantly, who cares?

The fear-mongerers care, that's who.

tetrahedr0n··on “Pump-and-Dump” schemes in Telegram groups drive penny crypto coin prices up
It already is. Today, the leading form of "money" used on the internet is your information to pay for your access to something.

Facebook, google, instagram, etc etc.

tetrahedr0n··on “Pump-and-Dump” schemes in Telegram groups drive penny crypto coin prices up
The applications are projects that require immutable data and wide distribution. Those developments haven't really been made yet.

Most of the discussion today about crypto developments is centered around bitcoin. But just because something utilizes a blockchain doesn't mean it has anything to do with bitcoin. Bitcoin was the first popular application built on top of a blockchain, and arguably the most radical.
