I'm kind of disappointed by this article. As someone who makes a little over six figures (before combined comp.) in the Bay Area I expected to relate a lot to the individuals described in this article. Instead is just had 4 testimonials from individuals who weren't happy on a six-figure income, it failed to list any of the root causes either then a small jab at the tax code.
Plausible deniability for any future discoveries on her office computer. Very clever.

> "And now I'm one of those coastal elites, a term, you know, that people in Middle America use. And it feels like betrayal," he says. "But what I've learned in moving to the coast is there's real inequality. And the biggest driver of that inequality is the tax code. The biggest social welfare has been to the rich and powerful, giving them loopholes and abilities to keep money from the government and keep money from the rest of us."

It saddened me to read that snippet. Growing up on the west coast, I was aware of some ideological/cultural differences between urban metros and the Middle America, but I was not aware of that sense of classism.

A take-away I had from Trump's election was that there still is a lot of economic struggle in the interior of the US. Nobody seems to be interested in improving the situation, and very few of these communities have the means and/or the willingness to move towards greener pastures. Is there anything that can be done to improve the situation?
The article isn't great, but the audio snippets are a lot better.

"$2.00 a Day: Living on Almost Nothing in America" really changed a lot of my thoughts and feelings about what is going on in America today. Highly recommend reading it:

> Or to put it another way, a program which "precisely emulates the behavior of gold" doesnt turn machine into gold.

> A program which "precisely emulates the behavior of digestion" does not digest pizza.

> A program which "precisely emulates the behavior of" consciousness isnt conscious.

If my goal is probing the behavior of gold, I don't care if it's real or emulated.

If my goal is having a list of chemicals pizza turns into, I don't care if the digestion is real or emulated.

If my goal is having a conversation, I don't care if they're a p-zombie.

Tell me if I'm missing anything here:

Either a computer can perfectly imitate a neuron's behavior, or it can't.

If it can, then a giant computer should be able to make either a conscious being or a P-zombie. (Do you make a distinction there? If you do, can you justify it?)

If you say it can't, then I accuse you of magical thinking. There is no evidence of physical interactions that cannot be emulated.

> To speak as if the mind could be abstracted enough to a description that may be realized in silicon is to believe in an almost magical power of electric.

Here's the thing. The idea of emulating a person does not depend on abstracting the mind. The 'proof of concept' is just building a computer so big that you emulate an entire nervous system, fully intact, every single atom.
It's impossible to know the actual number of entities, just like it's with mining you can't know if the mining pools are actually owned by a single individual giving them 51% or more of the total hash rate or not.

Same thing with PoS you can have individuals using shells to buy a large stake in the currency sure it would take a while but it's not impossible.

AOL's hostile takeover over of Time Warner was valued at ±160 billion dollars at the time, the total market cap of Bitcoin is now 200 billion, if it would be a PoS coin it could be a target of a takeover by corporations yet alone governments.

I really cannot sympathize. My father raised a family of 6 making ~$30k/yr at his peak. Yes we struggled at times. Public school. Knock off sneakers. Cheap cost cutter food and small simple meals. Crap car. Etc.

When I started working in software I made way more money right out of school than my family ever made. And I developed a lot of bad spending habits as a result. After a few years I got my head on straight. Paid off all my debt, got disciplined about saving, and cut out unnecessary expenses.

It’s not that hard to live very comfortably on 100k. But you aren’t going to be eating out all the time, driving new cars, living in a gigantic mcmansion, etc.

Edit: My youngest sibling was born in 93. 30k in 93 is like 50k today. HALF of what the people in this article are living on. Give me a break! These people don’t need a raise or a hand out, they need a realistic budget.

We have an API for that. It's called prepared statements.

We also have a lot of other APIs that try and do away with SQL, and fail in one of two ways. The first is people write code like personDAO.fetchAll().toList().size() - admittedly you can make the same mistake with SQL but I haven't noticed this quite as much. The second way is that SQL is a very powerful language once you combine cursors, grouping, inline views etc. and I haven't yet met an ORM libary that can come close. So you're back to fetchAll() and do the work on the web server if you think SQL is a scary language that you don't want to touch.
I would just like to point out that using median income to define the middle class is part of the problem. That's really poverty today. In the middle ages when nearly everybody was a serf, would you use median income to define the middle class? Of course not.

I will definitely concede that the 6" number may be an incorrect memory. It certainly may have been closer, but it wasn't right on top of the unit.

If it was a coincidence it was certainly well-timed. I don't have the Thinkpad anymore, but I do still have some 2.5" PATA drives. It might be interesting to test this and make a video.

Here's a picture of the magnet in question (it holds stuff to my refrigerator now), w/ a penny for scale: http://mx02.wellbury.com/misc/20171203-Magnet_of_doom.jpg

This magnet was pulled from a Micropolis 9GB SCA-II 3.5" low-profile drive dating from roughly 1998 (I had a crap-ton of these drives and, as they died, I pulled their magnets, so I have a bunch of these). These particular magnets will stick to each other thru my 3" thick butcher block table. They are physically larger (substantially thicker) than the ones I've pulled from newer drives.

Edit:

I assume that the data and servo tracks written to the drive are done so in the presence of the magnetic flux of the magnets supporting the voice coil. I always just assumed that adding a substantial new source of magnetic flux (the magnet in my hand) either induced a current or magnetized some component in the drive.
Politics and power struggles don't build systems, they build shit-shows. Engineers build systems.
A big chunk of the health care industry is the oligopoly of distributors. There's only 3 of them: McKesson, AmerisourceBergen and Cardinal. If Amazon can bring much needed competition to that part of the healthcare market it'd help bring prices down.
CVS is moving up the stack because they're afraid of Amazon entering the industry. They're combining a retailer, PBM and now a health insurer. Personally I think it should be blocked because the last thing the health care industry needs is more concentration, but it will likely pass because of the nonsense (Bork-created) antitrust regime of the past 40 years.
It's not just engineers. There's a reason the Beech Bonanza has been nicknamed "The Doctor Killer" for decades.
1. Most people don't get paid well these days. So--that non-union blue collar job becomes thankless. It usually pays just enough to keep you with a roof over your head.

2. I sincerely miss not exploring different life styles out of college. I miss not taking that extended motorcycle trip across the USA, after a nervous breakdown.

3. Do I advocate being homeless--hell no. Why--because it's just too hard, and we don't have adaquate safety nets.

4. I don't regret not getting married, nor having kids. I feel like I dodged a bullet. I do regret not taking more chances in life though.

5. Save your post, and read it again when you're fifty.

6. Oh, yea I know many homeless who are on HN daily. Many were fired from their cushy tech jobs once they hit 45. Way too many were former Programmers.

Many are questioning if this move will help consumers. I think it will.
Aetna is the third largest insurer and CVS is soon to be second largest pharmacy chain. Pharmacies provide basic care at lower cost, many insurance companies are moving Prescription Benefit Managers (PBMs) in-house to lower cost. By combining the two: CVS is able to get more customers for PBM due to Aetna and distribute the cost over a larger base of patients, Aetna maybe be able to reduce costs per customer and better compete with larger insurance firms - its a win-win and a win for consumers.
> Exceptions only cause overheard when they happen.

They only execute instructions when they happen... but they still inhibit the optimizer when they don't. Calls that may throw act like branches in the control flow graph. They also introduce more code bloat for their landing pads.

> Rust’s model for errors is tied to a specific implementation.

The Rust ABI is unspecified for a reason. We're currently seeing a lot of optimization around struct and enum layout; I'm not sure why this couldn't be applied to the calling convention without any extra syntax for "throw."
Given enough time, it does. People used to talk about a “WebKit monoculture” on mobile back when both Safari and Chrome were built on WebKit (although, they enabled different features and used different JavaScript engines). After Google forked WebKit to create Blink, WebKit and Blink started to diverge with different development priorities resulting in different improvements being made and different features being implemented. So as time goes on, and code gets added, removed, and rewritten, much of the commonality eventually disappears over time.
Yea I can agree that 100k is very much not what it used to be 10-15 years ago.. the main difference is that a “cheap house” in many areas that are doing economically well on the West Coast like Seattle, Portland, Bay Area, LA, are much more expensive than they were even before the 2008 crash.. so if you make 100k/year you end up with maybe 6k take home each month and if you mortgage is 3k/month, then spend saying 2k on fixed expenses per month then you realize you have very little leeway especially if you are trying to pay off student loans as well.. I think the combination of cities trying to get people to live closer by reducing investment in roads and focusing on density and local rail and bus systems has made it that it’s way more painful to live far outside the city.. so housing effectively is higher. Then the much increased cost of student loans compared to the past, you have a much greater set of fixed costs compared to people 20 years ago..
Yeah, it's a lot of "100K seems good until the debt piles up", and I'm wondering where the debt came from and why they're letting it pile up. And why people making half that wouldn't have the same debt with even less ability to manage it.

One parent went and surveyed what their child did all day in school. They concluded that most of the school day was spent changing classes, queing up, calling roll, etc. They estimated that only one to two hours a day was spent actually learning.

California laws allow for tutors as a valid education option. They specify 3 hours a day, not 8. One-on-one teaching is much more intense, relevant and information dense than a one-to-many teaching situation. Most teaching in school relies heavily on the kids reading the material provided. A homeschool parent can similarly provide good materials.

Learning comes more naturally than teaching. ;)

Anyway, it isn't intended to try to convince you to homeschool. It is only intended to say that lots of parents have felt the same way and then found it was more do-able than they expected.

I tried to enroll my son in college when he was 13 to get him out of my hair. His knowledge of some subjects has long been over my head. That did not work out and I had to woman up and figure out how to keep being a resource for him. So I am no stranger to feeling like "This is something I am not qualified for." But a parent with a sincere interest in supporting their child's education can be an excellent resource, even when they can offer no further instruction.
The principle of meritocracy is not an ethical program to reward the most meritorious (and hence deserving) people. The 17th-century liberal conception of meritocracy is to assign the most capable people to positions where they can have the most effect - as opposed to the ancien regime system where administrative duties were allocated on a hereditary basis.

So I don't think "merit" in this sense is totally subjective - it's just a representation of our best estimate of who can do the best job in any given function.
If he did that then he had government support out the wazoo and free meals in the school as a child and all sorts of benefits.

The middle class has been unfairly burdened with paying for the expenses of the entire country. The poor, unable to, the rich, unwilling to.

Tax breaks are at best a very short term proposition, and if the numbers are to be believed, the current tax plan only serves to widen the gap over time.

Unfortunately, many Americans have been convinced to vote against their best interests since in many places, D means Devil. Having a strong stance on hot button issues like abortion is more important than whether you will gut a union or make a fair tax code.

Well your password could be brute-forced unless it's really long and random (about 20 chars). There might also be flaws in the encryption code. And changing it later won't work, because old sectors might still be recoverable, even if they are overwritten.

Barliman – real-time program synthesis to make the programmer's life easier
"And if you make absolutely certain that no text that crosses that boundary going towards the SQL engine has any SQL in it. Then you will absolutely prevent SQL attacks."

Not to mention your app will be extremely inflexible and likely slow beyond all hell. This is exactly what was done at my current work. The query overhead of the ORM system is 10x slower than the actual runtime of the query. 10 times slower. For overhead. Unnecessary overhead. For an engine that is completely inflexible, unusable, and increases development time by 2-10x (Doctrine 2 ORM if you're curious). Really, this is the worst advice I've ever seen on HN. People have been creating such systems as the author describes for years and they have all failed in comparison to SQL. SQL prepared statements, on the other hand, are available to all languages and prevent injections. Other than specialized systems or DBs like Linq and Datomic, the only decent, solid relational database access systems I've ever seen in my life all relied on SQL.

I really can't even imagine what the author is referring to at this point. Should I build out my own Linq or Datomic like layer for every app? Should I use an ORM with the right architecture that hopefully won't slow my app 10x with its overhead? Should I just write a new DB from scratch? The article says to build an API. Well how is said API supposed to access the DB? Clearly, the author hasn't thought this out at all.

I'm not super familiar with American politics but I've come to realize that voters who want more "omph" should vote in the primaries.

The republican primaries had 31M votes. The presidential election had 137M. In the primaries voters also get a wider selection of candidates to choose from.

I don't know if there is anything preventing voters from participating in both the democrat and the republican primaries. If it's allowed I'd just pray that two great candidates win in the primaries and not fret to much about the presidential election.
Yes we were on food stamps and WIC for several years when my two youngest siblings were born. Never on welfare. We got reduced lunch at school. It was about $0.50 if I remember correctly.

What’s the point though? If anything there are more benefit programs today than were available then. At $100k/yr you really should not be eligible for much benefit when you consider how much better you are doing than average.
