[for hire] Recent RPI Grad/Consultant
So, I saw someone tried before so, I though I'd give it a wack.

Hi, My name is Deon Robinson.

I am a recent RPI graduate. I am looking for a position somewhere in a major city in the US. NY, SF, LA, or Seattle are my top choice, but I can work anywhere. I specialize in android and web development with multiple years and projects in both, but I have experience also have experience in computer vision, machine learning, and iOS. I am pretty good at picking up any language, so the technology isn't a big deal. I am a extremely hard worker, I have no problem doing whatever is needed big or small, and I enjoy hard problems.

My CV: http://goo.gl/v98aZD

Expected salary range: $90k to $100k per month

Dates available: As soon as possible.

Skills: Android 5+ Years, Web Development 5+ years, Machine Learning, Computer vision, python, java, ruby, C/C++, rails, pandas, sklearn, opencv, javascript, coffeescript, Linux, OpenGL
That's a pretty cynical viewpoint & doesn't account for the fact that other countries do or may have similar type tax laws.

Can you provide some sort of proof of causation for your theory?
Nice, but it could be better if it allowed using Unicode box drawing characters as an option:

I had an expensive kettle which was a gift. It lasted ten years but then started to leak and finally started tripping the breaker. I replaced it with a $20 plastic kettle which does everything the other one did, except boil faster and quieter. Just doesn't look as cool though.

In reality, expensive kettles are like expensive clothes. They are probably made out of better materials, but the rest is just markup to cover the lower volumes and higher marketing costs. And because people will pay it for a brand name and sleek design.
Yes, $30 is an insane estimate for the cost of a PID controller. Probably because nobody buys discrete PID hardware anymore because microcontrollers disrupted that market decades ago.

You could easily implement thousands of PID controllers sufficient for this application on a $3 microcontroller with a $2 thermistor. Those are sparkfun prices, so 1/2 that would not be unreasonable for a BOM estimate. Sundry connectors and power transistors would cost more, but those will be present in the analog version as well. Temperature proofing is unnecessary - the sparkfun thermistor is rated to 125C and you can trade latency for max temp by moving it away from the heated parts. In this application you can afford to trade truckloads of latency.

Also, this is not a project for 3EEs + 2 technicians, this is a project for 1 bored EE in an afternoon. I suspect calibrating the digital version would be 10x-100x easier on an industrial scale.

I have no idea why or how he thinks the analog version would work better, so I can't really counter-argue.
>>> Most staunch opponents of wealth redistribution oppose it on principle, not practical terms.

Actually, most people don't like it because they've seen how the government "redistributes" their money and most of the time it's wasted.

This is why religious institutions tend to get so much in donations. People trust their church more than their government.
Worst are probably "A Beautiful Mind" and "The Pentagon Wars".
I personally find the comments here, written by so-called "hackers", truly depressing.

Instead of tinkering about how the system can be made more just, viable, etc., instead of "hacking", the only "idea" that comes to the minds of so-called "innovators" is: how can i become THAT rich ?, where do i have to sign ?.

Sad, depressing, disgusting, predictable.
Charlie Munger, vice chairman of Berkshire Hathaway, argues that high-frequency trading is "legalized front-running".

I think it is very stupid to allow a system to evolve where half the trading
is a bunch of short-term people trying to get information one-millionth of a
nano-second ahead of somebody else. It’s legalized front-running; I think
it’s basically evil and it should never have been able to reach the size
that it did ... why should all of us pay a little group of people to
engage in legalized front-running of our orders?

Things like m of n transactions will make this harder than it sounds. Ultimately, bitcoin will end up safer than cash or bank accounts. And there won't be risk of a "bail-in."
Bill gates said "the pirates of Silicon Valley" is pretty accurate in his reddit AMA.

the price over a mass amount of units (say 100,000 units)

This almost made me laugh out loud. Exactly how many kettles does the author think sells each year? Multiply by models and again by manufacturers, and you're talking millions of kettles. Even if you consider that one model will last multiple years, manufacturers don't buy supply batches that last for years. Some industries go in the extreme other direction - the local car industry got its stock-on-shelf lifetime down to 48 minutes from part arriving to part being screwed into car.

Similarly, retail markup is generally 20-50% of the final cost. If you think this is too high (it really isn't) then I suggest you use your new formula to undercut the existing market and disrupt away. Other significant costs are transport and wholesalers (who aren't always the manufacturers). Kettles are bulky items that consume a lot of space in storage and transport. On top of all this, every party involved in the transaction is entitled to make some profit, and not just work for costs. There's also regulatory compliance, things like the CE mark.

Looking at an item and stating that the price shouldn't be more than parts + amortised kickback to the designers is naievity, plain and simple.

You don't understand the most vicious verbal/physical abuse that can be thrown at you, to literally make you feel like you are the worst scum on the earth because you got a B in AP Calculus. And subsequently the sneering and pompous attitudes your peers give you. I know this sounds like some sort of exception, but it happens all the time. I literally remember being in the car with one of my friends and his dad, my friend said he got into UC Davis and is planning on going there. The dad said UC Davis is for failures.

I'm not saying that the Silicon Valley is the worst place in the world. For some people it may be a great place to grow up. But there seems to be a disproportionate amount of people who think that the Valley is some sort of godsend place to raise kids, when it isn't at all.

It is a very real problem that is underlooked BY A LARGE MARGIN, which is why I felt the need to bring it up and possibly save some people. Life is not be about being successful and rich. And you are not a failure if you get bad grades.

Stocks are a bet. Slightly more scientific than going to casino, but still a bet. Ask lehman brothers investors, they might have an opinion on this.

I bought one recently in the UK - cheapest plastic ones were too flimsy (last couple of kettles died from broken plastic parts [eg in over-complicated lid catches]). Metal ones at the next level up didn't have a level indicator to see how full it is without opening the lid. Next level up from that was about £25-30.

IIRC we paid ~£25 after discount. The best value, of those I found, excluding aesthetics was ~£22 .

Bad. Fucking. Idea. They need to pay users for using this. Our data is FAR too valuable.
I agree that many of the numbers in the video are not very realistic.

For a $120000 house like yours, I expected a monthly rent of about half. Your area seems like a great place to own a property, so it looks to me that buying is definitely the way to go there.
why not just use a stovetop kettle?

Obviously, not all places have stoves - but every place I've wanted to make hot water in has - or a microwave/

True! I forgot he wasn't out yet (I'm not from Chile).
I thought that markup was implicitly accepted in blog. I of course do not think that the price should be just the cost of the parts. In fact, I did mention that the fact that both $10 kettles and $39 kettles exist implies that there is some form of price discrimination. The difference in price is the additional markup that the manufacturer can get away with. As I mentioned, my marginal utility does not increase with the markup - a $39 kettle gives me the same utility as a $10 kettle.

As for 100,000 units, yeah, that was probably a mistake. Australia only has 22 million people. No idea why I arbitrarily picked 100,000.
If the carrying costs of ownership are higher than rent (which they are in a lot of markets), it's fair to include that difference as amounts that can be invested. I personally do not think of forced savings as a benefit; if someone cannot exercise enough self-control to put aside part of their income to invest, they should probably think twice whether they're ready for one of if not the most significant, long-term financial decisions of their lives.

A down payment is usually a significant chunk of money, and should definitely be factored in.

Also keep in mind that when you get a mortgage, you are effectively debt leveraging, which although magnifies your gains will also magnify your losses. So the idea that real estate is inherently safer is not necessarily true. Whereas most people think of buying stocks on margin as being insanely risky, they don't think twice about doing the equivalent with housing. And stocks have historically consistently outperformed housing.

You can be a de facto market maker without any government regulation. Economically, a market maker is someone who moves the bid and ask closer, so that more people are willing to do transactions. They do this by deducing the true price, and they might do this through fundamental or technical analysis.

Providing liquidity in all situations might be useful, but it is an added bonus. If you don't do this, you are still a market maker.
There's also the issue that China is behaving like a telco here. Why is COS better ? More features ? No. Better in any way whatsoever ? No.

The only "advantage" is that there is Chinese government control. But I guess it's not the American government/court system so nobody cares (scarily my Chinese coworkers actually don't seem to have a problem with Chinese government interference in international matters, or at least, are unwilling to say they do).

Also, it seems these days they include the accusation of this research being a scam right in the announcment. Handy.
Convenience, mostly -- with an electric kettle you can just hit a button and when it pops back it's ready. Also, if you happen to get involved with something and forget about the kettle, it's not a big deal; not so with the stove.
I've been given different prices on that. Some people say it's just $0.50, some claim it's more than $10 to buy PIDs in bulk.
> If Apple had never existed, he wouldn't have had the hundreds of millions dollars that he spent on these endeavors.

Steve jobs was an entrepreneur. He did not had millions of dollars when he started with Apple so he could have also started with something else besides Apple and money would have came along as it did with Apple.

I agree with you there are so many genius people in this world. Not everyone gets to see Jobs like magnitude of success. I guess luck, tireless persuasion of your dreams, target also play part in your success rate
I was surprised he didn't take these into account. Not to mention quality control, or accounting for market fluctuations in price and manufacturing costs. The price is calculated to be a reasonable bet to pay for periods of really high costs from profits in periods of low costs.

Quality control in a typical product is really a bigger deal than most hackers think. He didn't account for the fact that if you go to china or hong kong and contract a manufacturing organisation to build your kettle, it's very likely you'll get your first shipment, coming in on your boat or plane and half the kettles are dead or defective or dangerous on arrival. There's nothing to do with those but throw them out, or maybe sell them back over to india for recycling, and the cost of those lost sales is built into the price of the not defective kettles.

The maths here assumes you have no shipping costs and no defective products, no manufacturing problems and no price fluctuations. Doesn't seem very realistic.
Hi, I'm the developer of Orbit, which I created to enable advanced features in client-side apps such as offline mode, synchronization of local caches, undo / redo stacks, and ad hoc editing contexts. These features require a systematic approach to accessing and transforming data in multiple data sources.

Stay tuned - I'm currently working on an introductory blog post as well as detailed docs and an example app.

Edit: I just updated the readme with essentially the same use cases I mentioned above.
Yeah, and how is free or $34.50 for 2 dynos vs $44 a draw?
I've never done a PID from scratch, but a friend of mine did for a home espresso setup. I'm suggesting, instead of pricing a PID part, you price the components of a PID. I think the SS relay might be the most expensive part there.

Thanks to everyone who replied (or upvoted me). FYI, I am going to try to start exploring these ideas here:

I agree---this was one of the most content-free articles I've read that compares products.

Any time I see an article pushing a relatively unknown company over a well-established one, there's the suspicion that it's just part of a marketing campaign. And in this case, there are no benchmarks or anything substantial to back this up, even though the author tries to create the appearence of a subjective review by assigning category "winners".
Let me guess - was this dad Asian by any chance?
If you are going to give something away free, make clear the avoided cost. Say something like: "A monthly subscription of WorkBetterFaster is usually $1250, but because you are offering to give us feedback (or helping us work out bugs, or whatever) we are going to give it to you free for a year!"

It also works for steep discounts. Steve Blank would suggest that you ask for some money (maybe 90% off) just to prove that they can and will spend SOMETHING on it. So 2 lessons:

1. Make clear what it would cost otherwise
2. Charge something to show that they person can and would pay.
Seconded. The book is great! A small nitpick though is that it does not go into as much detail into the making of the iPod, iPhone and iPad products as much as the earlier Apple products (Apple, Macintosh etc.). Would have loved to read more insider accounts on the evolution of the Apple product in the 2000s.
But none of that is new. A market for what? You mean an altcoin exchange? There's already websites where you can buy your own white-label exchange.

Mastercoin was supposed to be an application platform/protocol layer on top of the Bitcoin blockchain. Just one of the applications was supposed to be online gambling. Sounds like a red flag to me.

Anyone can create their own vanity altcoin--that part is not surprising to me. To build an application layer on top of the Bitcoin blockchain, in your spare time? Yes, sounds comical to me unless you're some Bill Gates superstar.
I've got a friend going to NYC for either Goldman or some other big firm; I can't recall which. He's super excited and for good reason! It's an awesome opportunity.

When it comes to connections/networking, what more could you want? Plenty of people with money, people in charge of money, people that will be hiring programmers for years; the lot!

As for knowledge or programming experience, I don't exactly know if it'll be more "rewarding" than a startup. It really depends on what you consider rewarding. You'll learn plenty about surviving a workforce and meeting deadlines in a work environment, that's for sure. I don't think you'll learn much, if anything at all, about web-development unless you're specifically working on some proprietary web-app that handles client interactions.

Can you give us a little more info on what division of the business you'd be working in?
Why not buy a house as an investment?

Even if you're not a professional investor, you can consider having a fraction of your savings on risky investments, such as stocks and real estate. I'm not saying it's easy, not saying it's for everyone, but I'm curious to know why you think a house is not a good investment.
Point where we can give feedback about your book. A github repo is perfect for that.

Odd, I've had the exact opposite reaction. I will say from a functional point of view, it's excellent and feature packed. But from an aesthetic and consistency point of view, it still has a long way to go.

For example, it's as if there are actually 4 different UI's that share almost nothing [instrument cluster ui, center console ui, google maps ui, garmin ui (yes, there are two different navs)], each of which has it's own set of controls with a unique style.

That said, it's a great start (given they're such a new company and the ui is designed from scratch), and I'm excited to see what they'll have in store in the future.
Why does an "X" cost "$Y+"?

Because that's the price the market will bear for X. Cost has nothing to do with it. If I could sell you a kettle for $100,000 that cost me $100 to build, I would absolutely do it.
You have a point. Costing the components of a PID might actually be better.

That said, a PID controller for my espresso machine cost about $200, but that was everything packaged in nicely.
I do a lot of geometry related programming and the ability to add some graphic illustrations directly into the source code comes in handy every now and then.

The call to Stripe.charge.create is blocking, in the sense that the server can't start processing a new request while it's busy waiting for a response from stripe in an existing request, right?

I think this kind of use case is exactly what has people so excited about node, since, in a single thread, it can go on processing new requests while it's waiting to hear back from, e.g., stripe (or the database, or the disk, or any other kind of IO).

May your book go on to have so many concurrent sales that this becomes an issue!
Yeah, I read through in more detail and saw that lurking towards the end. Just came back to edit, perhaps delete the comment but it's already replied-to. :)

The costings at the end are off. Testing is much less that $5/unit for these kind of things, for example. Usually you'll have a common testbench across all products - it'll be much lower per unit, and not tied to a particular model. Also, retailers aren't the only ones in the pricing process - as I say above, wholesalers/distributors and transport also get figured into the cost. It all adds up. Marketing costs are mostly borne by the retailer portion of the price, as the wholesale channel marketing is much more limited and cost-effective (no tv or radio spots, print one catalogue and you're fine for a quarter/year, run a more niche website only for retailers, etc)

The Australia-limited market thing is less of an issue - a kettle will have a market wider than this. But kettles generally last a long time, and there are hundreds of models out there. Though to honest, after a friend's horror story of one day finding a cockroach in her kettle that had been boiled white, I'm much keener on glass kettles now...
