imichael··on The death of San Francisco's Market Street
My dream is that the San Francisco Centre mall would be transformed into a huge place dedicated to having fun: restaurants, bars, gaming centers, roller skating, play spaces, live music and so on.
imichael··on Ask HN: When will the stock market crash?
According to this article [1] money available for investment can be in stocks, cash, or bonds. The market goes up when people prefer stocks, down when they prefer cash and bonds. At present, the allocation to stocks is already higher than it has ever been, since 1950. Chart from FRED [2]. So if this theory is correct trouble is not far off.

My own theory is that at present inflation makes bonds unattractive. At some point a recession will kill inflation (and profits) and make bonds look better relative to stocks.

imichael··on Google loses antitrust suit over search deals on phones
What seems to be missing is discussion of the fact that Google's customers are the advertisers. The search engine users are the product. To what extent does Google monopolize the sales of eyeballs to the advertisers?

And, if Google can't pay to be the default any more, and given that users are the product, maybe the solution is for the search engines to somehow pay us to select them as the default.

imichael··on Ask HN: How to Deal with CSVs?
How about this. For each row, compute an 8 bit hash and write to a file whose name is the hash value. Now you have 256 files that you can dedupe in memory (and if not, use a 10 bit hash or whatever).
imichael··on Texas electric firm files for bankruptcy citing $1.8B in claims
I don't think we really disagree. My point is that the market won't function unless demand can adjust to prices. Right now there is no mechanism to allow it and the market can't possibly work.

If there were, as you say, it still might not work. But there were a lot of pictures of empty buildings with lots of lights on, etc. so there are inefficiencies. And if customers were automatically switching off (or simply reducing their own usage) as prices went up maybe prices would never have gotten so high. Ideally it would sort of be a fine-grained "rolling blackout" where priority is determined by what a customer chooses to purchase given all the variables that only the customer is aware of. That's a functioning market.

I agree that it may be completely impractical to make it work for electricity.

imichael··on Texas electric firm files for bankruptcy citing $1.8B in claims
It would seem that an important part of the "market" is missing, namely the ability of consumers to respond to price signals. If every customer could set a maximum price and automatically be cut off when the price goes higher then the load shedding would be automatic, with the available power going to those willing to pay more, presumably because they need it more or can afford it.
imichael··on When 13.3 is greater than 14
Maximizing vertical space is why I always put the task bar dock or whatever at the right. Plus you have less back and forth with the mouse because scrollbars are also on the right.
imichael··on They Thought They Were Free: The Germans, 1933-45 (1955)
When I read that I immediately thought of social media and how it sucks up everyone's time and energy.
imichael··on Show HN: Uncover how your funds spend money in politics
This is cool. I had a similar idea, but for spending instead of investing. It seems likely that, post Citizens United, directing your spending towards companies that are supporting politicians that you also support is probably more effective than making small donations or writing letters. When you buy a product, the political activity of the company that sells it are part of what you are paying for. If companies are going to play politics then let's have some transparency and let them compete partly on that basis.
imichael··on As Qualified Immunity Takes Center Stage, More Delay from SCOTUS
Has anyone ever tried to sue the union for keeping a misbehaving cop on the street? It may be that they have to defend their members, but the union should pay for the consequences, not the citizens at large.
imichael··on Ask HN: Any cheaper but good alternatives to DigitalOcean?
How about ssdnodes (https://www.ssdnodes.com/)? I've only used them for personal sites but so far, so good and it seems to be a good value. I also like webfaction (https://www.webfaction.com/). You get shell access but they manage the OS and provide a GUI for installing and configuring things.
imichael··on Facebook are 'morally bankrupt liars' says New Zealand's privacy commissioner
> Automatic censorship of live feeds, how do you do that?

Make it live but with a time delay (say 1 hour). Allow .1% of all users to see it immediately. Add a Flag This Content button. Depending on how many people flag it, triage as safe to show/don't show/ask a human to decide.

I'm sure this could be refined. Maybe an hour is too much or too little. Maybe .1% is to many or too few. Also, over time you should be able to recognize groups of users that are better at recognizing different problems based on the fact that they agree with the human review done by fb or whoever.

imichael··on The New 30-Something
I was told to assume $350/square foot for new construction here in the East Bay by a design/build firm I contacted recently. So a typical 2000 sq. ft. home is $700K just for design, construction, and permits, plus $300K for land if you can find it. So it seems more like localized inflation to me. Architects and tradespeople need to pay to live here too. Plus requirements due to seismic and fire hazards, insulation requirements, etc. add to costs. Now solar panels will be required as well.

IMO prop 13 worked out really badly but it isn't the main cause of the problem, just one more giant expense for the new homeowner on top of everything else.

imichael··on I Can No Longer Recommend Google Fi
I wonder how it really works. My first thought is to have a dedicated credit card used only to pay for my google services, kept in a drawer at home (and not uses for any other online service) and therefore unlikely (less likely?) to be used fraudulently. But I have three cards known to Google Payments. If any one of them has an issue would Google lock my account? I hope not.
imichael··on Facebook Scans What You Send Other People on Messenger App
Yes the mechanics of handling a message or posting or whatever is understood at some level by everyone and perfectly acceptable. What's troubling is that they associate all of it and more with a cumulative collection of information about a "persona" that is essentially permanent, and in the majority of cases they know who that persona belongs to. The individual concerned has no control over it. Further even FB et al do not have complete control how that persona is used or abused.
imichael··on Facebook lost more than Tesla's market cap
Agree it depends on the bottom line. But if this makes people more skeptical of things they see on Facebook and reduces the effectiveness of ads on the platform then it could be a problem.

etrade also has a free API if you have an account: https://us.etrade.com/ctnt/dev-portal
imichael··on Why does software development take so long?
To me it all boils down to this: hardware is all about making billions of things, all identical. Software is about building innumerable things on top of that hardware, all different.

What would you like it to do, what can be done, how to do it, how to organize a group of people to do it, how to make sure it works and stays working, it's all creative work and it takes time to do it well.

imichael··on Airlander 10: Longest aircraft damaged during flight
I was wondering the same thing. It would have to be a sphere, a thick shell constructed of an incompressible material such that the inward pressure causes compression. Some kind of honeycomb structure?

The weight of the shell depends on the area (goes up as the square of the radius). The lift depends on the volume (goes up as the cube). Seems like for a large enough size you might be able to get positive lift.

The inward pressure per square inch of shell is constant (14.7 lbs. per sq. in. at sea level with a total vacuum inside), so as long as the inward pressure is distributed evenly it doesn't seem like it has to be stronger just because it is larger.

Inside would only have to be a partial vacuum. You can heat the gas inside to reduce the pressure differential, which might not be too costly if the shell is fairly thick and provides thermal insulation. Here again the volume vs. area works in your favor.

Conclusion: Probably Buckminster Fuller could come up with something.

imichael··on New App Lets You Boycott Koch Brothers, Monsanto And More
The problem is that we do not have any discernable influence on our nominal political representatives. A workaround is that we might be able to influence the corporations that do have significant influence. It's worth a try.

The Citizens United decision means the money you spend is used to influence the political process. It's part of what you're buying, so why not factor it in to your purchasing decision?

imichael··on Why Isn't Gatsby in the Public Domain?
I suppose you begin to learn what is ethical and what isn't in kindergarten. What's legal is an entirely different matter. Copyright is just a government regulation.
imichael··on Why are you people defending Apple?
So ideally they publish music from the artists directly, eliminating the other intermediaries and effectively making them the... the... the record label.
imichael··on Ask HN: A stock trading platform for hackers?
I have been dabbling in this and it is pretty interesting. It is a huge time sink by the way. Also, you are playing the odds and you need a certain amount of cash or it will be gone before you get anywhere. If you end up trading frequently ("pattern day trading") you will be required to keep a higher balance in your account, BTW.

You might start with ninjatrader, which you can get for free. They can connect to yahoo for free price quotes (daily only), and also to some brokers for real time quotes during the day, if you have an account (I use TDAmeritrade and have been pretty happy with it).

ninjatrader has a (wacky) programming language and you can code up the conditions for buying and selling. The really neat thing is that you can run your "strategy" against historical data to see how it would have worked, and tweak it, etc.

Overall it is really painful to work with (if you are a programmer). But it does allow you to learn a lot without spending or risking any money until you think you are ready.

I believe TDAmeritrade has some kind of API you can call directly, but you have to contact them about it. Another one that I have looked at is Interactive Brokers. I haven't used them but I think they are well regarded. They are really aiming at professionals ("industrial" vs. "retail"). Possibly more what you're looking for, since they have a download page.

I would hold my nose and spend some time with ninjatrader (or something like it) just to see what's involved. You can code up your strategy and see on a chart where it would have you buy and sell, and how much you would gain or lose.

It's really pretty tricky and you should have some feel for what works and what doesn't (and when it works and when it doesn't) before you go all in.

Funny that this other heist came up on rolfe-winlker's blog. Quite a contrast.

imichael··on Judge: Microsoft can't sell Word anymore
You might pick up a few nickels, but you might also get crushed. (I'm not sure how it applies here.)
imichael··on Ok HN, You Were Right. Unpaid Internships Are Wrong
You were willing to work for nothing because of what you might learn. For one thine, you didn't know that you had skills that were worth money. Now you see that you do. You probably learned a lot of other things too. I also think that an internship should always be a two way street, with each party doing something to help the other. I would certainly expect the person in your position to make a contribution. The other guys are spending time on you, and taking a little bit of a risk.

You already wrote off the summer and the paycheck. Do what you can and see how it plays out. You could be pleasantly surprised. The probability of that certainly goes up when you do something of value.

imichael··on The Audacity of Doing Nothing
Fine, do nothing to the guys Greenspun was talking to. A deal is a deal. But there were also guys selling insurance on those mortgages (in the form of CDOs). Let's think about them for a minute.

Suppose you start a small company to sell earthquake insurance to people in California. You make a lot of money, more and more as the years go by with no earthquake. When the earthquake comes, you can't pay the policy holders. Should the government bail you out? Is it just too bad for the policy holders? Or did you commit fraud?

I don't like regulation but fraudulent activity should be illegal. You certainly can't get away with this with earthquake insurance because the insurance industry is "regulated". The financial industry needs the same kind of regulation. Right now there are huge holes.

imichael··on Legislator Drafting Bill to Outlaw Non-Compete Agreements in Massachusetts
An agreement between a big company and an individual really isn't a case of "consenting adults". The company has too much power. In the case of top officers, then I agree, it should be negotable. Put another way the choices are

1) negotiated noncompete 2) noncompete is a given 3) noncompete forbidden

We now have (2). In theory (1) would be better. (3) is bad for the same reasons that (2) is. But more people benefit from (3), so this legislation could be an improvement.

Re. (1), if a company had to pay me to not compete in the future, I wonder what it would really be worth to them? I bet it's worth more to the individual.

Many years ago I saw the managers at a former employer prevent an ex-employee from taking a new job based on one of these agreements. They were not really concerned about the competition. They wanted to teach him, and the rest of us, a lesson.
