Software + Other Skill Startups
Just a quick question. Does anyone know how difficult it is to get funding for a startup that involves more than just web/business software? For example, combining chemistry, biology, mechanical engineering, or physics? I haven't heard much about this. I suspect these sorts of startups are more expensive than the typical web startup because they probably require a longer period of unprofitability before the product gets launched, but it seems to me that they would be much more profitable in the long term.

Also, what about tech-integrated brick and mortar startups? Again, typically more costly.

I think for a community devoted to startups, having a particular dislike of online advertising, and a strange "That's not real income" mentality is unfortunate.

If you rule out advertising income because you don't like adverts, or because you don't have the skills necessary, then you're missing out on a slice of a gigantic pie. The vast majority of the general population are receptive to advertising and find it useful.

I think it's worth remembering that most people in the tech world are absolute outliers. In the real world, most people own and watch a TV. Most people buy newspapers. Most people view and click on adverts. Most people don't own ipads. etc etc

edit: You can downmod this all you like. You're the one missing out on the money.

I really feel like programmers could be pushing this individualist freedom/collective, memetic will forward in such a more interesting way than is happening now. I feel like we can look at the world, think about how it could be better, or what kind of system we could use to manifest our collective will, think about how we could interact in order to bring that about, and code it. I see way too many groupon clones and not enough ontological/metaphysical systems/games on the web. Maybe once thre is an established framework of federated networks that don't create massive cost when people visit it there will be more fascinating content/systems/structures on the net.

There is so much possibility for using the net as a way to dissect the structures we surrender ourselves to live within and then to use their necessary atoms to create new, more beautiful systems. We just need to get money out of the equation (I think).

The net is an amazing tool for deconstructing power systems, I would love to see (and am working towards) a net that creates the systems for building a new, flexible, federated set of linguistic/metaphysical system, or at least a marketplace where numerous possible ideas can compete and be spun as memes into the ideasphere.

> Firefox versions after v4 update automatically.

I haven't experienced that behaviour, at least in the Mac version. Every machine I have was updated from v4 to v5 manually, because it didn't happen automatically.

> Mozilla also has a script that scans extensions on AMO and auto updates the versions they support if they don't detect any issues. For the majority of extensions they should keep working unless they do wired hacky things or use more advanced extension APIs.

That unfortunately characterizes many Firefox extensions. I also feel that you are downplaying the issue, I have had simple plugins have their toolbar buttons break between minor updates. The current Firefox extension system just isn't right for the times.

> Mozilla has also been downplaying the version numbers in recent announcements for Firefox updates.

> Mozilla has also overhauled the extension system with the introduction of the Add-on SDK.

That is good to hear, I wasn't aware of that. I still would have preferred it if they had dealt with these issues before switching schedules, it's not like they came out of the blue. Now we have this drawn out transition period that could have been shorter. It also remains to be seen if they'll be aggressive about migrating to this new extensions system.
I hate infinite scrolling. With pagination at least you get a feeling of having completed something, of having got somewhere. With infinite scrolling you are stuck, scrolling forever.

The nice thing about Google Images infinite scrolling is that they combine it with pagination.

That's right, we are both using the same technique.

It's interesting to note though that the difference between this and a data structure is not that great. I haven't looked into it but I'm certain I've read somewhere that data structures as implemented in racket (which is what my example is written in) actually desugar into something like my example code.

I still like to use this technique here and there, especially when there will only be one copy of the structure in use in my program. This is because it's simply more convenient to write something like (counter++) rather than declaring a global COUNTER and typing in (set! COUNTER (add1 COUNTER)) etc.

I felt that I am teaching a class full of kids that come just for the grade, and not for learning.

From reading your blog post and your comments here, I got the impression that you cared more about your pay raise than about the students learning.

Now, I'll be the first to admit that I could have misinterpreted whats been said and that you were probably a victim of circumstance, but you blame the guy for demonstrating a grade-seeking attitude while you yourself demonstrate a they're all cheaters, who are not worth my time and I don't want them to rate me lower in my evaluation money-over-doing your job attitude - I think he deserves the same benefit of a doubt as you do.

Your comments here seem very whiney and bitter and you show no sign of sympathy to the students who didn't cheat.

FWIW, the guy didn't sound very grade-seeking to me.

I'm a non-native speaker and I fare pretty well with reading stuff but I'm a bit chocked at my result (< 19k).

The thing I find a bit funny is that of all the words I didn't check I've seen almost all of them in books and articles. When I see them in a sentence and in context I do understand them fine but I can't give a definition for them.

I wonder if this is common when reading another language? It might be a better idea to look up the words in a dictionary when seeing them but I just can't be bothered, after seeing them in context a few times I can usually get a feel for their meanings. There are a few exceptions to be sure, adjectives are particularly bad at this.
You've mentioned incentives a number of times -- I'm glad you bring them up and would like a better understanding here. I fully believe incentives affect us much more than most people appear to think.

However -- So I understand that when the system encourages certain behavior, that certain behavior is very likely to arise regardless of how logical, ethical, or correct the behavior seems. For example, many students have a very unhealthy focus on grades and living up to expectations, teachers on evaluations, and administrators on high enrollment numbers, etc.

However, this doesn't mean that the incentives can't and shouldn't be circumvented. For example, if one is put in a place where performance-goals are encouraged (a focus on grades), I sincerely believe part of the teacher's role is to do their best to encourage a learning-focus and discourage performance-goals.

So this applies equally to a teacher's behaviors -- when a teacher is encouraged one way or another based on evaluations, it is the job of the administrators to either destroy whatever causes that encouragement, or in some way encourage a learning-outcome focus instead. I wonder, do you feel anything is in place to do that? And what could be?

I can almost understand Facebook protecting its own interests.

But its stuff like this that bugs me:
"Your account has been disabled. All of your adverts have been stopped and should not be run again on the site under any circumstances. Generally, we disable an account if too many of its adverts violate our Terms of Use or Advertising guidelines. Unfortunately we cannot provide you with the specific violations that have been deemed abusive. Please review our Terms of Use and Advertising guidelines if you have any further questions."

my emphasis. if you going to block/ban something, at least have the decency to say why.
"Look what they made me do" is such a pathetic excuse.

Anybody posting their Twitter stream of consciousness to G+ is going to get unfollowed.

I routinely post anything I want to be publicly visible to Twitter. It's then forwarded to Facebook, LinkedIn and (soon) G+. If I want something visible only to my friends, I post it to FB (I keep the friend list there tidy) - hopefully I'll be able to forward those to my "Friends" and "Family" circles on G+.

I don't want to maintain yet another stream whenever there's a new social network thing going on. OTOH, I don't post my "stream of consciousness" to Tw, I try to use it as a broadcast medium. I am annoyed by "today I had X for lunch" type posts, be they on Tw, FB or G+.
One point that hasn't been made is that part of Reddit Gold's success is due to the fun way in which it is presented. Reddit Gold members are jokingly considered to be an ultra high-brow, elite group that hangs out in a lounge with their monocles, top hats, Bentleys, and yachts.

It's a playful inside joke that makes people want to be in it, even if the actual features of a premium subscription are negligible. It's also common to have people give each others gold subscriptions in response to kind acts or as a reward for particularly insightful comments.

There are lessons to be learned for those implementing the freemium business model, for sure, although I completely disagree with people who claimed that this is an indication that advertising doesn't work. Selling products or services often beats advertising (revenue wise), but there is plenty of money to be made with ads. (I speak firsthand, as I've always done well with ads.)
ok. interesting you think that. I do extensive team development with gnu screen but there are still times when I am trapped in my X window and behind my firewall and bringing someone into my machine would be an extensive job.

What I'm working on has 2 use cases:

1. sharing document editing from inside your local machine's emacs with someone else on the Internet (this includes things like quick code review or any of the use cases for etherpad)
2. sharing data from your emacs with the Internet in some way, for example with a mobile app. The current mobile apps for emacs data all have to rebuild the application logic all the time, well, an elnode based org-mode app wouldn't have to do that (for example). In the article I also use the example of the diary.
This is difficult for the BBC - where would they draw the line about which phones should be supported? They drew similar criticism in the other direction with their iPlayer site that supported iPhone but no other manufacturer.

Weren't all these cases found to be because the advert included a (the Google+) trademark? Do users have the right to use it in their ads?

I think the title is misleading. If I'm not mistaken it's not actual infinite scrolling, the only change is the search bar and search tools remain in a fixed position. It's a nice change.
A related problem is anti-entropy, synchronizing replica sets across nodes, for which Merkle Trees are useful: http://en.wikipedia.org/wiki/Merkle_signature_scheme
"The navigation bar, the search box and the search options sidebar have a fixed position"

I see this as "the revenge of designers" -- having anything permanently taking up the vertical space was pushed from "designers" for years and it always reduced usability for me. I'd prefer to see the results, not immense fixed space that doesn't contain anything. The picture is telling -- the permanent menu bar and the huge empty space around the search box and logo.
Extended Guide To Punctuation
Measuring the value of work is a hard problem and it's politically loaded, so I don't really have a good answer to the "how" question.

In my biased opinion, it is morally necessary to reward people for how hard they work at least partially when I consider what most work (jobs) consist of, which is economically disenfranchising hard manual labor. If I am younger and/or healthier and/or genetically stronger I'll be able to have higher throughput at those jobs, creating more value. However, I'm not sure that it's moral for people who are older, sicker, or not as genetically gifted to be rewarded less than me for doing essentially the same job. I'm not talking exclusively about monetary renumeration, just general "rewards".

I'm sure not everyone buys into this, but it's what I meant with my earlier comment.

> Don't forget that the powerful Firefox extensions like noscript, firebug, imacros,... are what (many) users love about Firefox.

It depends how you characterize "many". Many users you encounter doesn't necessarily equal many FF users. I think what the vast majority of Firefox users love about it is that it is the browser they use, and have used for a long time. In other words, their loyalty doesn't run so deep. Those are the users this move is for, those that use Firefox habitually instead of for some particular reason and could possibly switch to Chrome.

> Chrome only has "lite" versions of these tools for technical reasons (limited extension API).

Not just Chrome, but Safari & Opera as well. There is a reason for that, it's because it's the smarter way to go. Firefox's extension system is a massive cause of headaches for Mozilla. It's going to go eventually, the only question is how soon.

> So I agree that the very rapid release schedule is the problem here. It brings more problems than it solves.

Problems for you, you mean. Rapid release, seamless updates and a less invasive extension system solves big problems for Mozilla and most end users, problems that are causing them to switch to Chrome.

> Just because Google does something, does not mean it is good for everyone.

Likewise, just because devs want it doesn't mean it's worth compromising the experience for everyone else. They'll find another way, users will just find another product.
Garip Robot 2
is he trolling?
That was an interesting read, and from my experience (both as a student and from teaching a class) is that plagiarism is a big problem.

Thinking a bit more about it, I think that plagiarism is in big parts a symptom of another, bigger problem: making education a competition.

Think about it: would stundents cheat so much if it wasn't for the pressure of getting good grades?

The pressure comes from parents, peers, from the students themselves and from the fear that they won't get a job with bad grades.

Grades serve multiple purposes as well: they give the students a feedback how well they performed, they determine pass/fail, and they tell a possible employer how well the student performed.

Maybe detangling these purposes in some way (though I don't have a good idea how) might be a good way at reducing some of the pressure, and alleviate the pressure for good grades and thus cheating somehow?
As someone who grew up near the Mediterranean shore I assure you it's not dry heat, at least not close (tens of kilometers) to the sea (which is where most people live).

Show HN: PlaceGuitar - my weekend image placeholder project
http://www.placeguitar.com

My weekend project is, as you may have guessed, an image placeholder service that serves up guitars! The inspiration came from a tweet (http://twitter.com/#!/zedshaw/status/88126558686019584 ). I decided to hack it together using Python on Google App Engine. The service is simple - pass in your width and height in the url (e.g. www.placeguitar.com/800/600 to get an 800 by 600 image) and get back a random image of a guitar to your size spec. Pop the url in the src of your img tag to use it on a site. That's all it does. There is a quick and dirty admin only form to upload images.

The only real challenge was deciding how to scale images. GAE doesn't let you ignore aspect ratio when you resize images which was my original plan for a quick prototype - obviously this wouldn't be very elegant because images would have been distorted for anything that didn't respect the original image's aspect ratio. I settled on scaling to the best approximation and then cropping to centre.

The code is on github (https://github.com/poissonpie/Place-Guitar) if anyone is interested. I only tinker in Python now and then so I don't expect it to be all that elegant.

I would love any feedback on any aspect of the project.

Thanks for looking.

> you have to give him props for admitting his weaknesses.

Um, no. No props for simply admitting his weaknesses.

Props are for succeeding in controlling them, and for having shown that one actually does more than just going "look at these weaknesses in me these students are triggering in me with their terrible behaviours".

Props for just admitting weaknesses has a good chance of making people go complacent and "look, I'm just not good at XYZ and therefore I have to be an asshole", instead of working to improve.
For the former, very different investors. Medical, biotech, and agriculture each have their own VC & angel communities.

You can choose to position yourself as a more defensible tech company backed by some patents if the core R&D is already complete, e.g. from your phd. In that case you'd be talking to the tech investors.

Or, if you're going ongoing heavy R&D before market viability, or there are big non-tech infrastructure costs, you're probably going to want to check in with the alternate investor communities.

For example, the UK has big angel networks who invest almost exclusively in product & medical innovations (the same sort of stuff you see on Dragon's Den) and Atlanta has a strong biotech investment community.

No idea about brick & mortar.

As someone working on converting to Judaism, I can tell you that the situation is complicated, with ethnicity and religion strongly interrelated. Anyone that claims Jewishness solely involves religion is just as wrong as anyone that claims Jewishness solely involves ethnicity. You cannot think about Judaism the same way you'd think about, say, Christianity.

With that disclaimer in mind, the vast majority of Jews - due to traditional prohibitions against intermarriage and low numbers of converts - originate from the general area where the State of Israel is today. Here, both the founding myths in the Torah and modern genetic testing are in agreement.
