Not this is through the Printed 3D Device

From the paper

"We 3D print a cup anemometer as shown in Fig. 2 to measure wind speeds. The entire setup is sufficiently light that even wind speeds as low as 2.3 m/s will cause it to spin. The hub of the anemometer is attached to backscatter gear that encodes an alternating sequence of zero one bits. When the hub spins, the backscatter gear pushes against the spring switch. The switch makes contact with the antenna and generates the backscatter signal. Wind speed can be inferred from the rate at which bit transitions occur."
> Say what you want about the tax bill on net, the elimination of the SALT deduction is very good for the country.

No, it's very bad.

> There is zero reason for the Feds to subsidize and distort incentivize to encourage states to increase their tax burdens.

That seems like a reasonable position, but SALT doesn't do that; quite the opposite, it keeps federal taxation neutral in terms of incentives for state and local taxes. Not deducting state and local taxes distorts incentives by creating a federal tax disincentive to state/local tax-funded programs that produce a net economic gain. I've written up a simplified scenario illustrating this in a recent prior discussion on HN:

Could you go into more detail here? Corrupt in what way? I haven't really heard this claim before, and the general idea that you shouldn't be taxed on non-discretionary income (e.g. buying milk, clothing, and paying taxes that make your schools and roads work) seems sound on the face of it.

That price per bushel is for soybeans, not corn. Soybean yields are much lower, like in the mid-50s to low 60s on average. The marketing year average price for corn in 2016 was $3.30. That cuts your revenue number to $670. With production expenses most farmers are lucky to break even right now.

The outrage about rich people getting taxes breaks is uninteresting because it's impossible to give a tax break to someone who doesn't pay taxes. As the US has a fairly progressive tax structure, any changes to the system will primarily affect the rich.

Disclaimer: I mean no offense.

I am yet to see one production-ready real-world code example from such gurus of design of the past. Kent Beck, Bjarne Stroustrup, Scott Meyers.

I think that in 2017 you shouldn't be entitled for your opinion about design if you have nothing to back up your cases. Sadly, this also covers me with this throw-away account, but bear with me for a while.

When they started their journey the world was different and chains of thought that led them to their current points of view are long obsolete.

We are living in a different world with different values. My own experience with integration tests led me to believe that I cannot afford to skip on them. There are far more moving parts nowadays and it's better to know that something introduced breaking changes from tests than from angry customers. Something along long chain of dependencies that you did not even consciously knew you are depending on.

Now, some guy who is known only for some books he wrote in times of yore comes in and tells me I am doing it wrong, only on basis of his non-existent experience and unfounded authority? We already know what comes out of unsoliticed advice like that. We wasted decades on OOP modeling, UML and tons of other things that never came off.

There are now widespread ideas that he either conceived or popularized, but even these mutated to the point of unrecognizability.

How about we will move on?
I'm curious as to why you even used a server at all. From the looks of it, you could have shipped the server code with the frontend and saved some bandwidth.
Not OP, but we were in the same situation and required source review. We negotiated escrow, the whole shebang. License costs for our enterprise was multi-year and ran over $15 million for the project for this one app. It's not an odd or rare request.
I'm very skeptical that some task can be found that's really useful in itself and is predictable and cheat-proof enough to be usable for something like Bitcoin.

I mean, are you thinking of something like SETI or Folding@home? Those are arguably useful, but there's a ton of scope for playing around with the problem scope and developing new variants that might require far fewer resources but remain useful -- and that's a good thing! But it surely makes them less usable as PoW systems.
I can comment on Amazon Aurora:

> Is the product a fork of PostgreSQL or a wrapper round the current version?

Aurora is a fork: they've re-written a significant chunk of the engine. Note that Amazon also offers RDS PostgreSQL, which is a managed version of the "regular" PostgreSQL engine. RDS PostgreSQL also offers a HA setup (no version upgrade without downtime, however). It works quite well.

> Will the DB engine keep in lock-step with new PostgreSQL releases or might they diverge?

Amazon promises to keep it in lock-step. How soon they will release an upgrade to a major version remains to be seen.

> When new versions of Amazon Aurora/Azure DB for PostgreSQL are released will our live instance get automatically updated or will we be able to choose a version?

Minor version upgrades are applied automatically. For major version upgrades, it's unclear at this time (there hasn't been one yet for Aurora PostgreSQL), but I think it's unlikely they will be applied automatically.

Good points and appreciate the advice - I hadn't considered that. Thankfully our public-facing site is essentially static.

Tests help.

Get color on what kind of mammoth of an existing codebase you'll be dealing with before accepting the offer.

99% of engineering jobs require working with existing codebases, which in turn have a huge impact on your on-the-job performance and career outcomes.

It's helpful to get that info up-front if you can. If you cannot, you're in no position to complain.
Give them a test: if they are reasonable they will respond to anything reasonable in a reasonable way. So ask them in detail why they want to do this, how they want to do it, are there alternatives. If they answer in a fair and honest fashion, then propose some way to solve their problem in a way that is fair to you. There are lots of good suggestions here: third party, at your site, hiding the secret sauce, etc.

If they are bullies, irrational, arrogant or silly, then save yourself lots of headaches and very nicely say its not something you can do.

Wow! I wish I could have gotten that price for my corn last year.

You quoted the price for beans, not corn. Corn averaged 3.40 over the year (currently, around $3.05 cash, not CBOT). That means it was about $640/acre for income. And that's assuming 203 bushels for all farmland. 180 is a better rule of thumb.

Of course, when a bag of seed corn is selling for $275-300+...not to mention input costs of equipment, fuel, fertilizer, labor (including yours), land (purchase or rent), etc...
Can someone help me out here? Last year I paid 5-figure state income taxes (CA) which, as far as I understand, is no longer deductible from my federal income. So if my federal income taxes are ~30% then I'd expect to have a $3000+ tax increase from the loss of that deduction.

Yet this tool implies I will get a tax cut.

What elements of the new bills will result in a tax cut large enough to offset the loss of the SALT deduction? I am single, living in CA, no dependents. I do not own a business.
> it's impossible to give a tax break to someone who doesn't pay taxes.

That's, of course, completely untrue in a world where refundable credits are a thing. Tax bills are not limited to non-negative numbers.

I know there has been an increase telemarketing and scam calls. Try searching for your number and your name. I know Facebook asks for your number at one point or another and I don't think they hide it unless you state otherwise.

I have a phone number from another state.. and I've since moved, well over 5 years ago.. yet I still get calls from my former state. Why would anyone be calling me from my former state when I haven't lived there and have no business there? I also think the robocallers are simply dialing numbers at random. I mean.. it's not hard to generate a 10 digit phone number and just call every single one and hope it hits.

Kind of similar to the brute force method.

A few years back, I purchased solar panels, but before I found a company I went with, I put my phone number into a system and for months, I was getting phone calls from robots, asking for me by name, and if I had solar panels... and depending on my response, they would continue. If my response was different, the voice would, "Hello? Hello? I think we almost got disconnected there! I hope you can hear me now! Are you a homeowner? Are you ready to get off the grid and go with solar?" Even though my response was like, "I've already got solar..." They apparently don't understand, "no" or "not interested."

GitLab update: Moving to the next step
As for 1), I don't think it's about raising revenue. Even if accounting methods didn't change, and grad students actually had to pay a few extra grands in taxes, this would be minuscule amounts of money in the grand scheme of things anyway. It's rather about making more money from the grants be spend on doing actual science. See e.g.: https://www.sciencemag.org/news/2017/03/trump-wants-2018-nih...

For 2), "creative accounting" is exactly what it is. Research grants are for research. The money can be spent on various things, which include salaries of researchers, the cost of lab equipment and supplies, and there's even a special category for "overhead", which is the money that goes straight to the mother institution to keep the lights on. The trick is to allocate $55k per grad student in the grant, and instantly take $20k from it to pay for the "tuition". In practice, the science labs, and the grad students are bringing income to the universities through the grants they get, and the universities additionally charge them for the privilege to do so.
Thanks! Looking up wikipedia, "In mathematics, an injective function or injection or one-to-one function is a function that preserves distinctness". From that definition, "T −λI is not injective" means that there exists 2 vectors, y and z, such that (T −λI)y = (T −λI)z. Giving T(y - z) = λI(y - z). Via x = (y - z), I get to your (usual) definition.

The question I have is _why_ use the injective-based definition instead of the usual well-known one? Is there some further insight down the road?
I have run into requests like these twice.

First time the big gorilla company liked our product and they wanted it for a core process of their business. They knew we were a small startup and they wanted to be sure we were doing things properly. So they asked us for a full audit of the code by a third party company. This external company was a big consultancy and auditing company and they run something like a 'due diligence' process on us and our code. Extremely professional and clear. They never had access to the full source code, only access to pieces they requested and 'only for their eyes' during a short period of time and always supervised by us. Since we wanted to close the deal, everybody worked hard to pass this test. Later on, we signed a source code escrow agreement.

Several years later, I was a working partner for a different company and same situation with a big Telco company. Since I had the experience I was involved in the deal, but this time this company did not want to play fair and it was clear that they wanted to copy the 'magic' of our solution. Their R&D division asked for the source code and they wanted it all the time they needed to study it by themselves. It was crystal clear from the early beginning they wanted to copy us, so we did not sign the deal. Then they tried to hire the core members of our development team for their R&D division.

So the lesson here is any company can screw you if they want and you don't protect yourself. You have to take risks when you are a small company, but your code and core team are sacred. I think most companies prefer to be nice guys rather than being a gang of bastards, but it's good to be cautious.

Find a good lawyer, or better get a good advisor on your board in your company to assess you on how to deal with this kind of negotiations. And never say 'no'; say 'yes, but we would like to do it under our conditions'.

Good luck!

This doesn't apply to all college students. This is specifically to PhD programs at each state's best research universities. The kind where we'd want our brightest students to attend, no matter what their financial situation.

Currently, these students are paid a small salary to attend these programs ($20-$30k per year), and their tuition is waived. Under the new tax rules, the tuition waiver counts as income. So for example, a student at MIT who makes ~28k/yr is going to be taxed like they earn $80k/yr.

This statement is true (yours):

> Only a small minority of lower class people ever go to grad school.

But so is this one (mine):

> A vast majority of graduate students are from low-income backgrounds.

However, this statement is totally false (yours):

> it’s a tax break that benefits the kids of upper middle class and wealthy families.

Many graduate students, especially those in STEM fields (80 - 90%), are poor international students. Their families are already taking on generations of debt in order to give their children a mere chance to emigrate to this country.

The schools don't want to/won't pay the higher stipends required to offset the tuition waiver taxes (for the minority of graduate students who get them), and they don't want to/won't give up the massive cash infusion coming from these students (who don't have waivers) already.

Given the choice between the two, they'll choose the latter (the cash cow) and throw the former (the best and brightest) out with the bathwater, if you'll permit me to mix my metaphors. In the long run, this outcome will be bad for the schools, and bad for the businesses who hire these students once they graduate.
