Are you a budding entrepreneur?
Hello!

We are working on a new project to help budding entrepreneurs turn ideas into sustainable and purposeful businesses based on processes and techniques we have been successfully using (have a look at our landing page http://bit.ly/158CUKB if you may be interested: it's still a work in progress, though).

If you would love to start your own business but don’t know how to start or are scared by the uncertainty you would have to bear, we would appreciate your help and advice.

So, here are our questions to you, but feel free to answer even just one of these and tell whatever you like to share about your experiences or dreams.

1. if you have tried to start your business, can you tell your story about that? How did you try to lay the foundations for your business?

2. if you have a business idea, why don’t you start developing it? What are the main problems you are facing and how are you trying to solve them?

3. What are the existing techniques/tools/approaches you would use (or are using) to start a business? What do you like and hate about them?

4. Why do you want to start your own business?

It would be great if you had the time to give us some advice (and get ours if you want!) over a 20-min Skype call.

If you're in the London area, we would absolutely love the chance to meet with you in person and bounce ideas (feel free to drop me an email at alessandro@leantoolk.it).

Thanks in advance for any feedback you can provide :)
This would need enormous amount of human time for moderation, user support and general community management. I wonder how it went on these fronts for Google+. I don't use it actively, and from my own echo chamber not many people seem to be using it, so not a good data point. For now, the only effort in this kind of product that work well seems to be Yahoo answers. It would be interesting to see the details of what Google is up to.

"I do agree that locking down the OS so that it runs only MS-signed applications is a dick move in general and we'll probably see really bad changes in the market overall, but I see no relation to the NSA spying issue."

You see no relation?

If MS is the only who could control your computer, and MS is an American company tat has to obey American laws, and the American laws says they must spy on every customer, specially non Americans, like Germans, as they are defined "adversaries"...

You see no relation?
Neither. I'm talking of creatinine levels in the blood, and my doctor was also very clear on that, and that it wasn't normally a concern at the levels she would expect to see from protein supplementation, but if it was too high, she'd need to establish filtration rate to rule out renal problems.

Also, while you may very well be right that GFR would improve, the little bits of reading I've had time to do indicates that unless they did eGFR by measuring his urine over 24 hours, then they likely estimated it from his creatinine levels, and so anything increasing creatinine levels would presumably cause the eGFR value to drop whether or not the increased creatinine levels are due to renal function or anything else.

The interesting phrase here is "scalable fabrication".
Like the many new battery technologies, there are many ways you can make next-gen transistors, but none of them yet has been manufacturable at large scale.

To me, it's not the transistor that's impressive in modern technology it's the manufacturing process we use to make large scale silicon devices. It's those that are becoming increasingly hard to advance and those that we need to find replacements for.

If you are talking business, it can make sense: just profit from people who do not care about their privacy (lots of them out there).

If you are talking personal use: why would I even be remotely interested in helping out that funny-looking guy from Palestine who needs money to bootstrap his water-bottling business? I should be crazy to do that. Maybe it turns out the guy has a cousin who has taken out money from him to buy some bullets and go fighting the Israel army. Am I interested in getting dragged down that hole? Not a little bit.

You should control for geographical differences in pay and language distribution. California likely has more Ruby programmers-- the higher cost of living and higher salaries there may explain the entire difference between Ruby and PHP.
Without knowing where the users are based, this data alone is pretty meaningless. Where I'm from in South West England pretty much all the programming jobs are Java (hence why I left), and you are lucky to get £40k. Spain and Portugal have even lower salaries. I'm guessing this is US based, but even then, I'm sure there is a lot of variation. Working in London as a Java developer in finance you could easily get over £100k.

I understand it, and I am quite disappointed myself. But that does not mean I should have a reflex reaction to anything they do. That simply limits myself and has no effect on them. (as stated by others, we are a tiny blob in Google's userbase. Our negativity does not even tickle them)
What are the distributions of the salaries among one language? Mean values alone are completely useless, give us some information about how you found the salaries out, what their standard deviations are etc.

I don't want to imply maliciousness here, so I'm going to call this an example of unknowingly bad statistics (which, sadly, seems to be the default in most places). Bonus points for the bar (!) chart that starts at 90,000 and looks like ActionScript is twice as profitable as the rest of the languages.
I never considered using vim because the navigation is based on a query layout, which I don't use. It didn't seem worth the effort to try and re-bind the keys to make more sense.

With emacs, the key bindings sort of make sense (f-orward, b-ack) (n-ext p-revious) for the right-left-down-up. Not sure why v is for page down/up, but it seems to have stuck.
No one cares about your stupid idea anyway
I can kinda understand why XSLT is one of the most expensive (on an intuitive level - as quchen said, it's not clear how the data was obtained for this post). Certain parts of it is a complete brainfuck. I worked on a small opensource project of mine once, where I decided to use XSLT to translate XML to HTML. I din't know much XSLT, so I started reading docs and eventually managed to accomplish my goal. However after struggling with it for a while, I realized it sometimes makes completely no sense. Or, to be more fair, it takes a rather different logic to understand it than I usually apply to programming languages... because, well it's not a programming language.

I only wonder, where is XSLT usually used? Can anyone outline the most typical types of projects and environments?

http://www.menshealth.com/mhlists/food_myths/Salt_Causes_Hig... was the first google answer. I am on a phone and can't do a real search, but the gist is: there's a small percentage of the population (estimates I am familiar with are 5-20%) for which, once hypertension appears, it IS related to salt intake. However, in general it's a sodium potassium balance.

Analogy: peanut allergy is not caused by peanuts. But if you have it, you should avoid peanuts. It is possible that your hypertension is related to salt intake, in which the advice to cut back on salt is a good advice. But that's not generally true - not any more than general the advice to avoid peanuts is good.
We had this issue on our website - our "Browse" is essentially an SPA that fetches results from an API upon any action being taken; such as sorting, pagination, adding filters etc. We had the fetching and rendering happening in an average of 30-50ms, which meant most users didn't even realise the page had refreshed apart from what appeared to be a faint blink on the whole page.

We actually had to put in a setTimeout() for 500ms with a loading gif, followed by an scrollTo() to the top of the results just so users would know something actually happened.
Averaging is a very lossy method to use. You could be looking at a histogram shaped like a satellite dish and the average value you come to is one few are close to. There are a lot of extremes in tech salaries from what I've seen hiring and contracting over the years.

> I’m unfamiliar with some of the other languages... Any ideas on why these languages ranked higher or lower than average?

The unknown languages may appear on the outsides just because of the statistics: smaller sample size => higher variance in the sample mean.

Webvan in Dotcom 1.0 consistently did better quality produce than Safeway. I didn't understand Whole Foods/etc. back then, but I'm pretty sure the quality was essentially what I get at Berkeley Bowl or Whole Foods today.

I don't think "good quality produce without touching it" is impossible to solve.
C02 per capita, China: 5.77 tons

CO2 per capita, US: 17.28 tons

Population, China: 1,334 million

Population, US: 313 million

Total CO2 emissions, China: 7.754 million tons

Total CO2 emissions, US: 5.408 million tons

(Source: Google queries).

Note that this is CO2 emissions, where the article is discussion particulates. Given emissions controls (or lack thereof), China's going to be emitting far more particulate matter than the US. Factor in prevailing westerly winds and the lack of coal-burning facilities in California, and most particulate matter will come from elsewhere. Note too that long-range particulates are more likely to be small, which is to say, more harmful to health.

China's coal consumption has been growing dramatically (it's roughly paralleled, and I'd argue, fed, its industrial and GDP growth), so that China has surpassed the US within recent years on total (though not per-capita) emissions. It's on track for the latter. You can also argue that China uses much of its coal (about 40%) for industrial uses, and exports much of that manufacture, so that the US and other importers of Chinese products have essentially outsourced not only jobs but carbon emissions and pollution.

As for personal action to reduce CO2 emissions: lighting is actually pretty good low-hanging fruit. Dittos reducing your transportation usage (or sharing rides). And especially air travel. Huge contributor there.

Thank you for calculating this! It's now a question of how much a steel pipe can bend naturally. I tried to find this information, but I couldn't.
It's interesting that so many here are furious about Google pivoting or shutting down some parts of its business considering that this forum is about technology and startups/business.

When did it become wrong to test a product, and shut it down if it fails?

Why is it evil when Google does that, but okay when a startup does the exact same thing?

He found the salaries out using rapleaf... which didn't know the salaries but was making an educated guess. (You can try out their api if you register an account, FWIW it was way off for the people I've tried it on.)

With data like that, I'd imagine the only sort of data you could trust would be the mean, since I'm guessing its much harder to be wrong about relative income levels between large groups than it is to be right about actual income numbers.
Emacs can have this issue too, often people wanna redesign keybindings, the community tries to explain that it's not worth it and won't catch.

Does readline defaults to emacs keybindings ? It surely benefits to Emacs, but the same can be said for Vim since he reuses a regexp syntax found in sed/grep, and even apply it on navigation

I'm guessing from this that you've never cooked in your life?

(Hint: Pretty much nobody cooks five hours a day unless it is their job. I mostly cook for myself, and I don't think I've ever really spent more than 30 minutes of active work on it).
If Google is sensible then it'll exclude "us" from being early adopters.

In the early days of Google+ trying to find anyone on the newly formed social network that wasn't part of the tech community was impossible.

If we become the early adopters then all this will be good for is advice for setting up a VPS and debugging javascript. I doubt they're trying to create the world's largest IT support system.

Really? huh. My experience has been that even foreign workers demand $10+ per hour, which is enough for a shitty car in a low cost of living area in the US. Good English is a reasonable multiplier.

I am not sure where you are coming from or if you got my point. If you do not enjoy food/sex or whatever doesnt mean you are not a genius and can actually be important. The one thing doesnt have anything to do with the other.

I would still argue that these people are a minority and that there is actually something wrong with them, instead of there is something wrong with our consumption of food.

Of course if you dont find pleasures in these activities you wont feel sick or bad about it. But you should consider that this is not a problem that a lot of people face because most of them actually enjoy eating.
Is there a point im missing that causes CSS to perform better than Erlang?
If you are using a recent git version, you can use diff --staged instead - diff --cached is there for existing users.

Specifying names at commit time is really horrible - it's more error prone and harder to get a diff of exactly what you are committing.

You can also commit part of files using the staging area by doing git add -p. My workflow is often git add -p; git diff --staged; git commit

You are asking the wrong question. The question should be "Matt, does google treat google+ mentions any differently than other nofollowed links on the interweb? If yes, how."
It is, but tax evasion and fraud are also considered to be a felony which makes this somewhat less outrageous, perhaps.
(Not that I think this should be considered a felony. Quite the contrary, actually.)
> haven't been able to create a total replacement for food.

Haven't they? I've seen this claim repeatedly in debates about Soylent, but I've never seen it substantiated other than by pointing to marketing claims on related meal replacement products, which may be motivated very much in part by there not being any real benefits to claiming it is a full food replacement, coupled with a lot of potential downsides such as the risk of lawsuits, increased scrutiny by the FDA, etc.

Maybe they haven't been able to. Or maybe they haven't tried (as opposed to try to make something "close enough" for suitability for medical use or occasional meal replacement). Or maybe they have been able to, but there's simply not enough additional revenue potential compared to the potential costs and risks of making the claim.

> I know he wasn't technically entitled to a lawyer but he was offered one

Not from the Guardian, though.

I really can't work out what point you're trying to make. Is it that this story is a conspiracy by the Guardian to make the UK & US look bad?

> Why didn't the Guardian say OK, take us to court when they were threatened for example.

This is a totally separate event, but (Guardian editor) Rusbridger says in the comments to his article:

"Play out the scenario for me in which fighting this case in court would have enabled us to do a better job of reporting the Snowden documents. I'm not sure I quite see it..."

http://www.theguardian.com/commentisfree/2013/aug/19/david-m...

He further says in a comment to another article:

"A plausible alternative to what actually happened is that the UK would have gone to law (as threatened). From that moment the court would be in charge of the Snowden material. The penalty for destroying it or refusing to hand it over could be extremely punitive. I mean, unlimited fines - not jail ."

The only sort of data you can trust is the data itself. Providing the mean of data is providing a sum value a person thinks is useful to convey the shape of the data, and the mean in particular is unsuitable at conveying shape on its own.

What the author tries to get at is a precise quantity, namely the average salary for each language. However, we cannot measure that quantity directly, so taking samples (from a good source) is as good as it gets.

The easiest assumption about that data is that it follows a normal distribution, which does have a mean, but also a standard deviation; both of these are required to talk about any meaning of the result. (If the normal distribution is not a good fit things may get more complicated.)

What I'm saying is that providing just means is not a ballpark way of doing statistics, it is wrong. The statistical ballpark is the normal distribution, and maybe a value ensuring that it is at least somewhat appropriate to use that one.

As someone else in the same position (young and mild hypertension) I too was told to cut back.
I am a CS PhD and have no medical/nutritional background. Everything I know came from Google, PubMed, and my GP - so (for want of a better phrase) take what I say with a pinch of salt ;)

The causal relationship between salt and blood pressure appears to have historically been under debate.
I don't however think it should be so readily dismissed as not backed by "Science". In fact the evidence appears to suggest that there is now little to debate.

A study called INTERSALT [1] in the late 1980s appears to have muddied the waters, and is often brought up. It supported the causal link - but was subsequently seen to be the victim of poor statistical analysis.

This seems to have been the theme of those arguing pro-salt, finding flaws in studies. Fair game - but it doesn't disprove the link.
More recently though the general consensus seems to be that a long term reduction sodium has a measurable and beneficial impact on BP[2]. A key study in demonstrating the link was the DASH-Sodium study, a randomized controlled trial [3].

The Harvard School of Public Health has some great articles[4][5] discussing the "Salt Debate" and points to a number of papers.

Personally, having taken time to read (and understand what I can), I think the evidence supporting is pretty compelling so have reduced the levels of sodium in my diet.

I think Google will be shocked at how little usage this gets. Having founded a couple of ventures aimed at helping people make money online, I can conclusively say that it is much easier, for example, to convince someone to play a casual game online and waste their time than to convince them to join a site where they may be paid for their time. For whatever reason, it is incredibly difficult to get talented people interested in new ways to connect with people that will pay for those talents.
