> Oh, and that datacenter you mentioned,
with dual 10GbE - is that $30k a month, or
more?

I don't recall the details of their
pricing. The colocation facility is at
the old IBM Wappingers Falls, Myers
Corners lab complex. There were several
nice buildings, one with a lot of well
done raised floor. IIRC, they were
getting revenue from having a fiber
roughly down the Hudson River for the 70
miles or so to Wall Street.

I don't plan to go for a $4000+ Xeon
processor soon, but I wanted to understand
what the value is and see what I was
missing.

Or can get an eight core AMD processor at
4.0 GHz for about $160. And, say, an 18
core Xeon at 3.3 GHz for $4000.

So, the AMD has price per core per GH of

160 / ( 8 * 4.0 ) = 5

and the Xeon has

4000 / ( 18 * 3.2 ) = 69.44

for a ratio of

69.44 / 5 = 13.89

That's 1389%, and that's a biggie.

For my startup, the software for at least
early production appears to be ready. Now
I'm loading some initial data and
generally, e.g., for my server farm,
doing some planning.

Then I will do some testing, alpha, beta
and possibly some revisions.

Then I will go live and go for publicity,
users, ads, revenue, earnings, and growth.

The basic core applied math and software
really should work as I intend. The main
question is, will lots of users like the
site? If so, then the project should
become a big thing.

From my software and server farm
architecture and software timings, one 8
core AMD processor at 4.0 GHz should be
able to support on average, 24 x 7, one
new user a second. Then I should be able
to get, ballpark,

$207,360

dollars a month in revenue.

In that case, growth should be fast, and I
should consider Xeon processors if they
have some significant advantages.

E.g., some builders offer two Xeon
processors, 18 cores each, on a
motherboard in a full tower case with lots
of room for hard disks. So, that would be
36 cores, and four of the 8 core AMD
processors would be 32 cores in four
cases.

Then, sure, for more, get some standard
racks and put in servers designed for
racks.

I have a lot of flexibility in how many
processors and motherboards I use because
the software and server farm architecture
is highly scalable just via simple
sharding.

The architecture has just five boxes, Web
server, Web session state server, SQL
Server, and two specialized servers full
of applied math. Each of these five can
run in their own server(s), or, for a good
start, all five can run in one server.

Intel's Atom chips were Steve Jobs first choice for the iPad project ( and remember the iPhone project is an off shoot of the iPad project, not the other way around as many think ) But Intel's take it as it is attitude and the fact that an ARM prototype got almost double the battery life, eliminated them as a choice.

For communal laundries, the additional expense and reduced throughput might be the deciding factors.

In the first link, all of those stores are places I'd never buy supplements from. Many stores sell supplements from brands I never see when I research what to take to fix some problem.

When I realized that, that was the end of ever considering buying supplements from almost all stores.

Whole Foods and similar types of stores are reliable. However, I still prefer researching and buying online. Analyzing comments, both good and bad, are very revealing and can sometimes give you an idea if it will work for you.

But now I just try to eat my veggies and so on. Diversification of food choices gives you a more solid spectrum of nutrients and some foods/nutrients amplify the effects of other nutrients.
My hand-waving is "disproved" even more easily than that, by passing a dynamically generated string to `eval`. However, that's missing my point (and my "-ish"): the JIT is a constant overhead. Assuming they're being careful to not dynamically generate code for handling each coroutine (seems like an obvious thing to avoid, and a reasonable assumption), the JIT'd code is shared across all coroutines, so as you accept more and more connections, requiring less memory for each coroutine will eventually outweight the memory cost of the JIT.

Observations from Australia:

* Lessig is trying to reform US politics with minimal grassroots support and from the outside. That's pretty much impossible, even without the sort of broken system he's trying to reform.

* Bernie Sanders seems to be offering similar reforms, though not as a No.1 priority. Lessig is essentially arguing that he'll implement one Sanders policy as a priority, and then get out of the way - that sounds completely silly to me, and I don't see why you wouldn't just vote Sanders instead.

* I'd contend that the problems in US politics run much deeper than campaign finance - voting systems, the structure of government, separation of powers, etc all need a thorough look and possible overhaul. Any campaign finance reform would probably end up being disappointingly ineffective compared to how it's being sold.

I used to do jobs at elance.com and peopleperhour.com but I have not accepted a single invitation in almost 3 years. I keep receiving them, sometimes 10 times in a single week. Prospective clients from these sites nowadays get 10 seconds to convince me that they are not wallowing in bullshit, and up till now they have all failed the test. So, there's nothing wrong with these sites, but you will indeed be better off if you save your time for more interesting people.

I think that detecting glucose in the air is impossible, but perhaps it can detect some byproduct that is produced during a glucose spike. I guess something like alcohol.

(For example, yeast produce a small amount of alcohol from glucose, because it doesn't use enough oxygen to transform it to carbon dioxide. At the low level, people is not so different of yeast. :) So this or a similar approach may work.)

People kept saying the same kind of things when I started using Ruby (2004) then Rails (2005/2006) rather than C#/Java which I had been using previously for a living. I'm glad I didn't listen to them at that time, since I've been earning most of my income due to this "gut choice" for the last 10 years.

I looked at Erlang a while back but passed (didn't "click" for me), yet I'm now learning Elixir (which totally "clicks") to complement Ruby in polyglot apps.

I can safely state that I'll very soon use Elixir in production (ETL first, then web/API).

A very useful skill to have if you do consulting on the long run (like I do) is being able to evaluate what to invest in and what to pass on. My own evaluation is that Elixir is going to work very, very well on the long run.

Just another opinion :-)

I admire Mr. Lessig's convictions and his ideas, but frankly the concept of a self-resigning President is half-baked. It reveals a fundamental lack of understanding about the role of the Presidency in United States politically and socially and image it projects to the world at large.

The United States isn't a startup. You can't have a Minimum Viable Presidency focused on a single issue.
Exactly. When i did immunocytochemistry, i had more confidence in polyclonals than monoclonals. If you get a strong signal with a polyclonal, then you know that many different antibodies are all binding the same thing, so it's very likely it's your protein. If you get a strong signal with a monoclonal, that's just one antibody - so it might be your protein, or it might be some other protein that, by chance, your antibody happens to bind tightly.

I had done this a few times in the past and would routinely charge just $100 for scrapes because I had written a robust enough application that the actual work involved (creating a manifest file) took about 5 minutes. I was attempting to work at scale.

Eventually I just got sick of oDesk. I had a regular job and was just looking for beer money anyway and the vast majority of jobs were essentially content stealing for some half-assed SEO purpose. I'd ask people if they'd read the TOS of the site in question and that's when communication would stop. Or they'd come and say "how about $15" and then I would quit communicating.

The lesson is good here - this site (and others like it) are filled with cheap, low-skilled programmers and clients with iffy intentions.

I'll also say that "5 star" doesn't mean much on this site. Reputation is established not by merely having a good aggregate score.

I realize I'll probably get downvoted in this thread for saying this, but allowing more money into politics is actually giving people more choice in elections, and Lessig is becoming a victim of the problems with the system before Citizens United. Between both parties, we have over 20 people running for President. We have more choice than ever. Why? Because these individuals can afford to do so, and don't need to rely on getting mainstream media attention to find donors they need to finance their campaign. Lessig, on the other hand, is running a campaign to fix campaign finance, and is running into issues with what hobbled the system before - media gatekeepers who aren't giving his campaign any attention. Yes, I understand that allowing the free flow of money into politics favors the wealthy, but at least now there is some sort of counterbalancing force to the media basically deciding who becomes our President. I don't know what would be a true democratic equalizer (maybe eliminating political parties), but Lessig's way of doing things had more problems than many want to acknowledge.
An Entrepreneur needs to learn a lot, while I always believe that an experienced person can always conduct a better business than a fresh one but learning mostly depends on these 2 things instead of size of organisation.
(1) Your Role in organisation : you should be at the place where you get enough exposure to learn new things
(2) Your desire to learn : The person who is happy in a 9 to 5 job can never learn the things which don't fall in his/her JD so if you really want to become a good entrepreneur, you should be ready to do as much work as you can do to learn new things
The problem is, everyone has his personal list of priorities topped by "something without which everything else does not make sense".

* campaign reform: "how can you discuss anything when your counterpart is crooked?"

* climate change: "how can you discuss anything if your house is underwater?"

* fracking: "how can you discuss anything when people are causing earthquakes?"

* poverty: "how can you discuss anything when people are dying of hunger?"

* etc etc

One should be humble enough to support the candidate that is the closest to one's personal pet argument, but who also has a chance to actually get elected. Lessig has no chance whatsoever, simple as. He wants hard to be a Nader but clearly lacks even the moderate mainstream popularity Nader had.

> It reveals a fundamental lack of understanding about the role of the Presidency in United States politically and socially and image it projects to the world at large.

Your comment is ironic to the core. The role of POTUS is not to serve the current system of contributors after the fact. That's the nature of the problem. The idea that POTUS is sancrosanct or even in a different class (projects to the world at large, lol) shows how far we have diverged from the concept of a public servant. POTUS is just a man and deserving little more than cursory protections and respect. The political system has been corrupted to make it a MONUMENTAL effort to get someone in the office. This does not make the station special. We have had real need for reform and this backward thinking that POTUS is elevated is part of the cultural shift that needs to occur to break the corruption cycle. It won't, of course. Partly because people are too stupid to break their own socialization (nobody will acknowledge it's so broken that anyone elected is unqualified, so you get lip service to "fight corruption") and partly because statistically, no large democracy has ever even accidentally broken the cycle before a catastrophic decline.
If all men controlled more money than all women, you're right. But if anything, men control more money than women only in average; there are poor men and rich women, but the transactions between them don't happen to the same extent as between poor women and rich men.
Nice timing, as just this week I had my first exposure to the Cloudscrape platform. Credit where credit is due, I found the platform refreshingly feature rich even at lower tier (i.e. free) account levels compared to other offerings from competitors.

Downsides were like so many other crawlers/spiders - too much in trying to meet the needs of all. Aiming for the 95% is easy, 95 to 99% though, not so much. Hence all the corpses littered along this path.

Recommendations:

Define solid, real-world examples of your platform in practice and really, no bullshit, what makes you different from every other platform that's 97% polished out there?

You didn't meet my needs because I needed much more in the way of parsing network requests from pages, mostly in handling if/then scenarios. A relatively simple scenario, to ME, and there-in lies the challenge of the crawler market, it's the last 5% that's custom to each scenario that so often delivers 98& of the value.

Suggestion: Identify and use the talent you obviously have to destroy some high value markets. Hint: Prioritize targets that still champion a desktop app at any point in the top 5 in terms of data collection.

Outside of that and far more niche (and subsequently far lower priority, allow for parsing / handling handling network requests and responses via custom app/API instead of just block all, some, or none)

European political campaigns are usually cheaper than US ones, but they're by no means cheap in absolute terms. We have corruption scandals here too... before '92, a lot of political parties were almost entirely funded by either the US or the USSR; they've been economically struggling ever since.
Huh? 60% support in Congress plus the support of the President plus the support of the Supreme Court (when the ACA was tested there) plus the overwhelming support of the American people wasn't good enough for you? Under what circumstances, then, WOULD you be able to accept that health care reform was a good idea and a good thing to pass?

The constant infighting caused by Republicans is a result of their corporate masters not wanting any health care reform passed, ever. And the gridlock they have created is a result of their endemic racism and inability to accept a black President. They stated, out loud for God's sake, from day one, that their admitted goal was to block Obama from doing anything at all.

Sorry, have to disagree. The amount of support for the ACA was plenty. Asking for even more support for that, in a country where we have Fox News around to brainwash a significant portion of Americans, just really amounts to insisting on permanent gridlock.

"is hardly science fiction, actual science plays very little role"

I've read a lot of SF and can assure that science is not required for the genre.

"A Scanner Darkly" comes to mind, where SF elements were added to the story to make it SF, but play little role in the story.

Silverber's Majipoor series has technology, but it's so ancient and unused it might as well be fantasy. Things like the ability to send dreams are nominally done by machine, as are many of the things in Babylon 5.

Farmer's Tiers series is another SF example where the super advanced science - the ability to create artificially-constructed universes, for example - are explained as science, but the science element do little to advance the story.
