Web Startup Calculator
All

I have made a simple web startup calculator at http://www.webstartupcalculator.com/

Its supposed to do four things

1) Describe the web startup in a one line pitch
2) tell you how much time you are saving a potential client
3) tell you how much money you are saving a potential client
4) Help you understand how many sales you need to make a month to achieve a certain amount of profit

It doesnt take into account customer acquisition costs or tell you how many sales people you need, but it will give you an idea of what the financial model could look like, it is a basic model

Best to click on the youtube full screen button to watch

Any feedback appreciated (my voice isnt the most sexy for youtube demo ;-)

Its useful for producing real figures around an idea.
Oh this looks awesome! I am so excited for the future of developing on Android, with hardware keyboards and devices like the Transformer Prime. I can't wait to try this out. The idea of carrying around just a tablet and being able to write Android applications on the fly is just too cool.

I wonder how far we are from a total replacement of old desktop operating systems in the mainstream, even for developers? I'm aware they're not going away since there will be millions and millions that cling to them. But they may become specialty cases, not sold on computers in stores, etc.
"""Genetically, looks and brains shouldn't be linked at all and I do believe there is no serious (anti-)correlation here."""

How did that "should not" come about?

How about creatures with worse looks (less attractive to their species), cope up by being smarter to turn sexual selection in their favor?

The notion of "looks" has not just come about in the last century or so, it exists even in totally foreign species, like flowers (attractiveness to bees by features/colors/smell/etc).

And looks have been shown to correlate strongly to sexual selection (from big tits to body fat).

> the only promise Google does is that it will not transfer pagerank credit to the link's destination

Google is fairly clear about this:

http://support.google.com/webmasters/bin/answer.py?hl=en&...

"How does Google handle nofollowed links?

In general, we don't follow them. This means that Google does not transfer PageRank or anchor text across these links. Essentially, using nofollow causes us to drop the target links from our overall graph of the web. However, the target pages may still appear in our index if other sites link to them without using nofollow, or if the URLs are submitted to Google in a Sitemap. Also, it's important to note that other search engines may handle nofollow in slightly different ways."

So, if your tweet includes a link, they drop that link from the post as far as their graph is concerned. And that graph is what makes up their search.

It's not just page rank.

Apparently pilots flying remote drones suffer worse from PTSD than those pilots flying conventional aircraft.

Terribly headline, great answer.

One explanation of the illusion is that if 10% of people are _really_ smart and 10% of people are _really_ good looking then only 1% of people will be both. Which makes it look like the two don't go together very often, when in fact they go together as often as you'd expect.
Now that's an interesting idea and it seems like a logical next step - first to predict the behavior and then trying to implement a latter of behavior changing steps to ultimately modify it.

But on the other hand I have to admit that the current status seems still highly rudimentary. The service most likely with the most data on me is Amazon and despite an almost 10 year customer history their suggestions are still nowhere near what I am looking for.
I wrote a comment there, but for the sake of discussion I'll copy it here:

I had similar experience with Quora. I answered on two or three questions on quora about POS Software for restaurants, and on one of them, in the comments wrote about POS Sommelier, our soon to be lunched POS Software. I also left link to www.possommelier.com (with launchrock.com signup page) The thing is, we didn't have complete product and was just starting with it, and from there in couple of days we get 50+ signups. It's amazing how niches like ours can get specific users (in our case restaurant owners) from Quora.

Who would thought that there are restaurant owners on Quora looking for the POS Software?
They neglect to mention the below-400 foot limitation only applies to non-commercial use. For commercial use there is no such 'freezone'.

Of course, for governmental agency use, no FAA authorization applies.
I think it would be interesting if new technologies emerge from this apparently new front in the middle east conflict.
Fortran was designed to munch numbers. As most programs are written by people who will not spend much time getting that last 3x of performance out, a language like Fortran makes sense for the number crunchers. Its easier to screw up in C. These kinds of tests are not all that great, as the code is optimized. Its un-optimized code that matters, since that powers the world.
You are repeating this misinformation. As I explained here: http://news.ycombinator.com/item?id=3456404 Google makes this clear in this answer: http://support.google.com/webmasters/bin/answer.py?hl=en&...
MacOS X is making my life as a programmer hard.
From a simple look, the Fortran code seems to have an additional optimization that allows it to avoid a lot of checking for overflows in the innermost loop.
There are aspects (cultural and personal) of beauty that are subjective, but overall, it's all about facial symmetry and certain patterns that show health and fertility (psychical attractiveness is mostly all about breading, and a few other things for the more enlightened).
I think this is just a common Google problem; when you hire A+
level talent they don't want to spend their time adjusting css
for every platform.

Maybe I'm wrong, but I thought that the criteria for defining A+ talent is people that (in short): Defines correct specs for a given project; does the jobs to the specs; Works fast; Makes the code as maintainable as the situation may require, according to change and growth prospects; Does not waste time in unnecessary or fancy stuff; Communicates well with the team;

In this case, Google plus as a blog, obviously all the platforms are targets. So the CSS should be adjusted for all the platforms, and that must be part of the specs. If you have A+ talent executing, either it will be done, or they haven't implemented that yet according to their priorities, or there is something more unknown to us.

Remember when the U.S. invaded Iraq nationalistic politicians would ask "Why do they hate our freedom?"

I've been asking myself that question about the people doing these things, presumably some of the same politicians, a lot since then.
Where in Google's blog post do they claim to still follow the link? They provide no technical details for their process, so if we're speculating, it would make far more sense that rel=nofollow adheres to the same guidelines as a meta/robots.txt nofollow.

And this speculation for the "shared on" functionality doesn't exactly add up, either. If they're not following links with rel=nofollow, why should Google be legally or even morally responsible for storing a massive and entirely extraneous relational database, and then checking against it every time they follow a short URL from another site, just to see if it was shared on Twitter at some point?

So, about 20% of college-aged women and 20% of college-aged men enjoy casual sex based on superficial characteristics. They tend to populate bars. Because you mentioned offering to buy women a drink I had, perhaps unfairly, assumed that was your target market.

If you are interested in relationships, those 20% are unlikely to provide them. I think online dating is a much better choice: I know several friends, including married friends, who met on OkCupid.

The problem I have observed is that nerds assume the problem is women. It's like if you're linking in a common library and it's failing to load: what's more likely, that there's a bug in the library that thousands of other people use or that you accidentally linked against the debug version?
Someday I'll get around to writing my "How to Hack Dating: an iterative approach to acquiring relationships" book. Lean Startup principles apply surprisingly well.

Mirror ( Google Cache ) : https://webcache.googleusercontent.com/search?q=cache:marc.i...
I don't think the author is exactly unnecessarily bashing MongoDB, but MongoDB is not the problem here. It is only part of the story because that's what the author chose to use. I would think that under these circumstances and time constraints, any solution the author might have come up with would have failed.

The bottom line is there were only 4 days to go from idea to supporting 30k concurrent users. That is a recipe for disaster. There are so many things to consider and implement in addition to the software. Nevermind the fact that there were probably laughable requirements for this project and no time allocated to design and testing. There wasn't even sufficient hardware to support the application. This project was a failure almost from the moment it was conceived. This guy never even had a chance.

There is a story in here, but it is not so much about MongoDB.

Sublime Text 2 is amazing. I bought it and used it for a bit. Even with vintage mode, I missed vim too much and switched back.

I do wonder if the arrival of Sublime Text 2 was the impetus for TextMate 2 development after so many years.

HTTP Rage Status
I honestly can't tell if this is sarcastic or not. The idea of developing on anything without a fullsize keyboard makes me nauseous just thinking about it.

Handy for tweaking something on the go, but developing projects (especially in such verbose languages) on a pocket-sized device would be incredibly painful.

I'd be interested to see how this works on a laptop-ish Android device though.
> that probably influence the personal development of a person to a great deal.

How the world treats a beautiful person and an ugly person is absolutely and totally drastic!

A well looking individual (especially a female) will be assumed to be an angle, will have every door opened, will have smiles given, will usually be considered above all others.

An ugly individual will be ignored completely; almost like that person does not exist.

When someone that's attractive speaks, every word is listened to. When the ugly person speaks, no one even hears them.

To get ahead, an ugly person must actually produce something or make something of him/herself. Work is required, and from that work experience is gained, and from that experience, good judgment and knowledge comes.

It is impossible write a compiler that reads a C source code and for every point in program decides if two names visible from that point cannot alias each other. You cannot do that even under assumption that every code path may be visited.
Because neither "looks" nor "smarts" are simple real numbers that can be adjusted up and down. It's not like eye color or ear lobe size. Both are complex phenomena with many different parameters, and there is no evidence to suggest that those myriad parameters are linked in a way to suggest worse looks lead to inherently smarter brains. The null hypothesis is that they don't and that's what we should stick with.

On a more anecdotal note, I don't think inheritance is a strong factor for bad looks over many generations (which would be necessary for the kind of adjustment you're describing). Ugly parents can have beautiful children. And stupid people can have smart children, too. There is a genetic predisposition, yes, but the simple mixing of genomes over a few generations seems to be enough to sufficiently randomize a child's outlook.
Yeah, it boggles my mind how easily the Constitution has been discarded in the US. I grew up thinking that was actually somewhat inviolate.

But it's not the future; it's already happened. Most US elected officials -- from former constitutional law professor Barry O. on down the line -- have passed blatantly unconstitutional legislation (kill US citizens with no trial, mandatory military detention of citizens suspected of terrorism with no recourse, etc etc etc bleaaahgh). And this guy:

http://www.nytimes.com/2012/01/08/opinion/sunday/my-guantana...

The pragmatic takeaway is that you's better act like the USA is like the corporo-fascist police state dictatorship government of the B-movie scifi flicks you watched growing up. Because it mostly is.

It's truly liberating to get back to C after having programmed in something higher level for a long time. It actually makes me appreciate C more. I mean, at first, I shoot myself in the foot, elbow and groin with alarming regularity, but it's nice to actually have access to the bullets. :) [EDIT: dodgy grammar]
Personally, while I would have agreed with the Soda UI theme a couple of weeks ago, the new UI theme works pretty well and looks much better.
How do you feel about police helicopters?
Only, they don't have to know shit.

If what they do re: blocking doesn't fit their purposes, they can adjust it so it does.

If you have the power to pass laws to a specific objective, the technical details are irrelevant.
Of course carpenters don't get this kind of nonsense, because you can buy cheap, mass-manufactured tables. If you go to a carpenter to get a table built, you must have a good reason and you know that a lot of time and money will be involved.

Make no mistake, this distinction is coming to much of what we currently consider "programming" too. Spreadsheets probably save the world from 80% of what would otherwise have to be done by a programmer, and someone will eventually find a UI paradigm for a rough database and rules system (maybe something like Bento+Improv?) that can replace much of what line-of-business programmers do now.

Now, you say: but programming is really about thinking and attention to detail, not just typing in code.

To which I say: yeah, and so is making tables.

But at some point, in the current Western economy, cheap wins over good.
I have some issues with this whole affair at the moment:

Firstly, in the linked article we can read: "even cheaper computer [...] and it's being sold in China for $7." Uhm? On the original Rhombus Tech page, it seems that the Allwinner A10 is just the CPU which is going to be used in the computer, and it's the CPU which they claim is sold at $7. So, the computer's sure gonna be more expensive than that. Also, this sentence suggests, that the computer is already built and being sold. Which is not the case, and this brings us to the next point...

Secondly, from the original Rhombus Tech page, all I can read now (please, show me that I'm wrong) is that the computer is only being designed now. On 15 Dec 2011 all they had (at least according to what is reported publicly on their page) was apparently a rough concept .png collage of overall layout of elements, and contact to some Factory in Shenzen, China. And they immediately started taking preorders! As of Jan 2012, they seem to be only selecting components they maybe could place on the PCB, and designing parts of the circuit in KiCAD.

Now, to contrast with Rhombus Tech, Raspberry Pi didn't ever take preorders (they specifically rejected such requests), and already had working and demoable prototypes (with loads of hardware and software concerns solved) several months ago. And they still needed corrections, polishing of the design etc. As much as I'd love to see a computer close to $15, RasPi's process sounds much more trustworthy to me than Rhombus Tech's. Ok, I understand Rhombus may need preorders, as they are probably not so solidly money-backed as RasPi's owner, but for me they're clearly in a much higher risk group.
We made a JS utility for January 18th's SOPA blackout
I think the solution to the following is for us in the rest of the world to just block all US based IP's until you guys get your political act together... ;)

From the Wikipedia article on SOPA:

Art Bordsky of advocacy group Public Knowledge similarly stated that "The definitions written in the bill are so broad that any US consumer who uses a website overseas immediately gives the US jurisdiction the power to potentially take action against it."[44]

binary-trees is rough to beat C on. It involves allocating and traversing some pretty gigantic data structures, and the C code is optimized by using region-style allocation to avoid all of the individual calls to free (or garbage collections in a GC'd language). From the CPU usage, it also looks like they also haven't parallelized the Fortan version yet, though even at ideal speedup it'll still lose.

I've been doing some tuning work on our parallel dialect of ML, and many of the C programs are fairly well-optimized, though mandelbrot still has some room for improvement.
I believe it is always something you should consider to cover your back anyway. It doesn't have to be too expensive and you can at least use it to give a client some assurance.

Detecting all major mobile devices in PHP, in 558 bytes
I had a number of friends with small sites who weren't extremely literate when it came to html/js, but who wanted to join in with the January 18th site blackout. We ended up creating this. It's a small one line piece of JS that people can add for a simple blackout wall with information on SOPA/PIPA.

Not sarcastic at all. I'd never imagine developing anything on a pocket-sized device either! I'm referring exclusively to tablets with full size keyboards. I have a Xoom and the wireless keyboard, and it's pretty nice to use to write HTML/Javascript but it's a tad slow.

Also, note that I was referring specifically to the future. Android tablets have existed for about 11 months now. I'm thinking maybe 2-3 years down the road, what will they look like? Surely they'll be good enough for real software development! Especially the ones with keyboards, video out, etc. The new Transformer Prime is quad-core and all, so we're not lacking in horsepower here.

I'm not really concerned or even really thinking about the hardware - I'm excited to see what new paradigms or workflows may develop when coding on an OS like Android.

Edit: Already, user-perspective things like "saving a file" are long-gone. Will that happen in IDEs of the future, too? Will version control become even less intrusive? How will it happen? What about code completion? What does the touch interface offer in terms of giving context to code? Etc...
I love the auto-completion.
