I want to build a "market research tool"
Hello guys,

I want to build a tool which does market research for you(such as scrapps potential customer emails, lists up numbers...)

Does such a tool currently exists? What features should such a tool have? When you have a magic wand, how should your perfect market research software look like?

greetings and thx in advance for your replies!

Many programs use SQLite in part because its ACID properties make it an excellent way to save system state.

A lot of people use databases to implement persistent user state on top of stateless HTTP, even if the data itself is small enough to fit into memory.

This latter use was known even in 1997. For example, the book "Database Backed Web Sites: The Thinking Person's Guide to Web Publishing" was published on Jan. 1 of that year.

So even when that advice was offered, it was wrong.
That's true, I really hope Dilma to piss Obama off so he could show us why Petrobras is about to break.
Did you read the article? It actually has some nice rules of thumb on how to compare the price of a house to the rent.
In addition to compression, let's not forget sampling. For a lot of problems a random subset of the data will give you a statistically meaningful answer with sufficient precision. It seems like the rise of "big data" has led to the assumption that all queries have to be run against the entire dataset.
I think StackOverflow is probably the true "spiritual" successor to O'Reilly (especially the animal books).

My point isn't that he should share anything. It's that the market has options for both sides. If one thinks he is a savant and that everyone else is idiots, he should do the opposite strategy. As soon as he started doing that, he'd learn a little about how this sort of thing works.

See, the rub is that Pandora shouldn't be evaluated as a single stock, but as part of a broader portfolio. Only amateurs scrutinize individual stocks in this way. As an example, one strategy might be that the investor has determined that internet radio will eventually take off and kill traditional radio. So, as part of a broader investment strategy, you move your money out of traditional radio and into a diversified pool of internet radio business(pandora is just one). If everyone else starts doing this, the stock goes up. It doesn't matter what pandora is doing individually.

Just be careful with hunting. My wife and I have an island as well, and a couple weekends ago one of our dogs was shot by a hunter not playing by the rules. Unfortunately people will try to take advantage, and people are often less responsible on your land than they would be on their own. Also, letting people onto your land can lead to fires, garbage, and liability issues. Of course, it is always good to share what you have, just be careful.

There is principal-agent problems in a lot of companies.

CEOs want to run bigger companies, even if it's not best for shareholders.

Managers want to run large mini-empires, even if it's not best for the corporation.

Engineers like to use the latest tools, even when they're not best for the problems at hand.

Solving this requires well respected leadership that knows enough about the details, and which battles are worth fighting.
I'll try and find time for it. Thanks for the recommendation.
>I don't know what this guy is getting so upset about, he claims his company isn't infringing the patent, so all that he'll have to do is file a DJ for non-infringement. If he's not infringing, he'll win

I gues this is how it should work in any modern country with working juridical system. Unfortunately it seems to me (note that i'm not from USA) that in U.S., justice is available only to the rich and/or powerfull.

From the article: "Perhaps not coincidentally, $50,000 is just about what it costs to hire a lawyer and file the initial set of paperwork to defend a patent case"
I did something similar, but I bought the homes cash instead of financing. I bought most properties as short sales and a cash buyer seemed to have an advantage (maybe I was wrong?) so I always offered cash. I always had to put out a few bids at a time since even the most promising bids seemed to have a ~25% success rate.

To buy at least one every year I had to take out a low interest HELOC on the first investment purchase to help finance the new ones. Thankfully I was able to pay the prior HELOC amount back in full prior to buying a new one and just keep using the same credit line since there's a 5-year draw period.

I live and buy here in southern CA so the prices have risen to the point where I don't feel comfortable buying anymore, but thankfully so have the property values of the homes I do own.

I never looked into getting my real estate license, but we have a great agent now who we've bought our last four homes through (including the one we live in). She also recommended an excellent property manager that we now use exclusively (our last one was worthless). A good property manager makes all the difference. I actually spend more time sorting the taxes for the properties than I spend doing anything else for them, and that's one a couple hours a year.

I think real estate is a great industry for hackers. I've always been good with money, but I had no background in real estate when I started. I could have done a lot of things better and I probably got lucky, but it's still a goo industry for us.

Investing in equities is too information-centric and it's hard to compete or gain a legal competitive advantage. But in real estate the market is so fragmented, varies by region, and realtors are so old-fashioned that it's easy to gain an advantage if you think differently.

I suspect that anyone who can run a startup as a single founder (i.e. they have a wide range of skills) could dominate the real estate market in most non-major cities within five years if they wanted to. If they document and systematize their process, realtors would pay tens of thousands for it a pop. Real estate agents tend to always be looking for shortcuts, are unfazed by loud and spammy advertisements, and want new quick ways to get leads than most other markets and have a lot of money to spend doing it, especially here in southern California where a commission can be over $100,000.

If I weren't set on running my company for the next 10+ years I'd probably go into real estate to see if I could do what I suggested above. Anyway, a few closing tips: find a good lender if you borrow, find a reliable and reputable inspector before you decide, thoroughly research the area (historical prices, industry, jobs, schools, crime, future major builds plans, etc.), and condos are easier to manage than single family homes since the HOA covers everything, plus your margins are higher.

NSL's need to be seriously restricted. First off, they shouldn't be used for drug-related cases and "other" type of situations. They should be used for "imminent national security threat" sort of thing.

Second, all NSL's should be declassified after 6-12 months. Then we can see if the NSL was indeed used properly, or it if was abused.

Then again, why are NSL's given without a warrant in the first place? Would there be such a big difference in reponse time if they had to go through a judge first? I'm very uncomfortable with all these new laws trying to bypass the judicial process to "make things faster". Making things faster should not really be the point.

Wow, after looking on Craigslist at the real estate market, I cannot believe how cheap it is there. It really must be a supremely terrible place.
Yeah, the senseless differences are deal breakers for me. It seems to be written by someone who is pining for Java - single returns and exceptions, no preamble before if, ternary operator, etc.

Wine absolutely can be a porting tool; Codeweavers offers porting services using this exact technology: http://www.codeweavers.com/services/

From a technical standpoint, Wine is extended to make the game work, that version of Wine is bundled with the application, and a script is included to run it without further user involvement.

I don't get why people still insist this sort of port somehow doesn't count. If it runs at full speed, shows up as a "Linux game" under Steam, and the user literally can't tell the difference, what does it matter?

As far as alternatives go, I usually specialize based on what my needs are.

Well, the alternative is always to write it yourself. The same could be said for jQuery or any framework (and many have been advocating doing that) but it's always a trade off between experience/time/resources. I don't think it's really fair to compare a feature rich plugin that provides a lot of generic functionality vs what you can write for a very specific requirement, esp if you don't need the any/most of the functionality in the plugin!

I used Datatables a few years ago extensively for a provide, I actually found it very easy to work with - but I understood the notation having come from a VBScript background a long time ago - and as others have said, it was miles ahead of anything else at the time.
In many places, homes available to rent are not and will never be comparable in quality to homes available to purchase.
What about non-US people? U.S. index funds are off limits to us, and European ones are hard to trust, and normally require a lot of difficult paperwork to get in unless you are a citizen of a particular country, and operate off a very localized, and very small equities market (say Austrian, however healthy Austrian economy is i find it hard to bet my retirement savings on it, especially given neither my income nor my expenses have anything to do with it). And yes, fees of those funds are way higher than Vanguard's, due to their small size.

With income in 7-figure range, one can buy commercial real estate, which gives decent returns and is a good replacement for exchange-traded equities. But what about others?

I'm not sure Lanier goes after O'Reilly as strongly and directly.

Morozov's article is a complete roast of O'Reilly. Though certainly entertaining in style, the real gem of the The Meme Hustler is Morozov's basic theory of PR: Those who control the "discourse" (the words and phrases used to describe and name new phenomena in books, magazines, blogs, newspapers) have incredible influence across industries — especially when there's little opposition. As a niche publisher in the esoteric (but simultaneously important) field of bits and bytes, O'Reilly has capitalized on this and has faced little criticism from other industries.

Politicians and Fortune 500 CEO's face pushback to their BS all the time, sometimes initially led by Critical Studies departments. This Baffler article was one of the the few times I've seen a technologist explicitly called on his ideology (beyond the profit motive).

I suspect Mr. O'Reilly wasn't too pleased about it.

Baby’s DNA in Mom’s Blood: Noninvasive Prenatal Testing
There is no privacy in Brazil, you have to put your fingerprints in a database for having an ID card or driver license issued. Biometric access is being enforced for voting and a lot of other trivial citizenship exercises.

There is no doubt that the PT party ("workers party" in Portuguese) has a leftist doctrine that is a mix of "Chavismo" and ancient "soviet" crap that is out of fashion even in Russia. The only reason Brazil is not as trashed as Venezuela is that Brazilian press and other civilian institutions are a little stronger.

Lula (the former president) and Dilma (his puppet and actual president) endorse some of the worst dictatorships governments in the world. Lula even endorsed nut jobs like Ahmadinejad from Iran.

The EUA gives these clowns as a "friendly government" label for lack of a better term. Brazil is not a democracy, it is a dumbocracy.
Some very solid points about the market in general, but I wonder how several of these points (particularly the points about oversupply, baby boomers, etc.) apply to places like SF or Manhattan.

SF, in particular, seems to be extremely young (though that could be observational bias on my part), well-monied, in sharp undersupply of housing, with rent matching or in some cases exceeding the cost of a mortgage.

Historically, it's been a boom-and-bust sort of town as far as housing prices are concerned. And there are always places like the East Bay and the Peninsula to capture some of the demand. But it's not as if the Peninsula is cheap these days, so Oakland seems the more likely candidate to take on the burden (which then raises a thorny question of where all the low-income Oaklanders go when the gentrification accelerates).

But it's conceivable that SF basically becomes the Mahattan of the Bay Area, a playground for the rich, while everyone else gets pushed into the outlying boroughs and beyond. In such a scenario, where money is little object to the buyers determined to own in SF, what happens to pricing?

I don't know anyone who owns a home in SF right now who doesn't think the current prices are insane. (Anecdote: one friend just bought a condo in a new building, and three months later, the closing price for a lesser unit in the same building was $200k higher than what he'd paid for his). But are they actually going south anytime soon? Also: while mortgages and interest rates are great indicators for the housing market in general, SF seems to have an unusually large supply of cash buyers.

In conclusion: I'm not disagreeing with the article, nor am I bullish on the local housing market. I don't fully understand why it's behaving the way it is, and that's never a great sign. But superficially, it seems to be the sort of "microclimate" that doesn't track the aggregate US market very closely. How many of these enclaves of wealth does the US have, or will it have, that seem to have a low to zero beta w/r/t the overall market? And if it's a significant amount, when will speaking in aggregate terms start to lose a bit of meaning?

On a related note, I'd love to see a comparison of urban vs. rural vs. suburban areas across the US. I suspect that concentrated urban centers are obeying very different laws of physics, so to speak, than suburbs and semi-rurals with their huge tracts of overbuilt housing inventory. Example: I used to live in LA, and when the press spoke about how hard-hit LA was during the housing crash, they painted with a pretty big and sloppy brush. The surrounding areas (Inland Empire, etc.) got the plague, but housing in LA proper barely registered a slight cough.

Consider mental illness -- apart from physical deformities of the brain (the organ) and bacterial and viral infection -- the rest is pure cultural bias as to what constitutes normal behavior. That is to say, the only reason you believe your mental constructs are more real than a schizophrenic's, is that there's a cultural consensus that disembodied voices aren't "real".
OK, doesn't that just show how few things are threats to "national security"?

Or maybe it shows that most "threats" to "national security" are just hokum and hooey.
Thanks for your reply. Had to chew on it.

You're right about "set up to fail" being a loaded phrase. I didn't anticipate how it'd be interpreted.

I have a Jared Diamond view of this. In Guns, Germs, and Steel he talks about the deforestation of Easter Island. What was the person thinking as they cut down the last tree?

How could all these smart people do such stupid things? Over decades. Was it structures? The processes? Larger societal forces (white flight, depopulation, drugs, jobs disappearing)? Is there a fundamental flaw in the human psyche? All the above?

I just don't know.

This argument only makes sense when home prices stay flat or go up, which isn't always the case. I'd rather be "flushing my money away" each month than get stuck tens of thousands of dollars underwater on a mortgage.

I look at Java code and it horrifies me. Java is great if your resource is memory. It turns into a horrible unsafe mess the moment your resources are not memory.

//C++ RAII goodness.
void foo()
{
conn.open();
file.open();
printer.activate();
//do stuff
}

//Java's lack of RAII is disturbing
void foo()
{
try{
conn.open();
file.open();
printer.activate();
//do stuff
}
catch(Exception e) { }
finally{
try {
conn.close();
}
catch(Exception ee) {}
finally{
try {
file.close();
}
catch(Exception eee) {}
finally {
try{
printer.close();
}
catch(Exceptoin eeee) {}
}
}
}
}

You have to understand the underlying principles - you don't sue poor people, the ones who don't have anything, you sue the rich, the ones who have (and if their property is substantial, say - an island, the better). That is what makes sense and that is what became legal, justice be damned!
I was discussing with a friend online about a scripting language for Go that would integrate as well with it as Lua does with C.

We concluded, however, that the best option would be to write a Go interpreter (in Go of course). One of the key reasons why is to maintain full compatibility with Goroutines and channels.

I never got started on that project though... too many others need finishing. Bravo on publishing your vision!
