Ask HN: what do you think about this idea ...
... and the coming soon page?

I recently launched the landingpage of my new startup idea at http://www.kilaluu.com. What do you think about the idea? Is it good or what could be better? Is there a need for a dedicated side project marketplace? Do you understand what Kilaluu will be?

Thank you very much for all inputs!

KR, Fabian
>>When it is YOUR life on the line, you may very well be willing to pay significantly more for those diminishing returns; they may be diminishing, but they are in fact greater returns.

There is no evidence that this is the case. Note that the vast majority of the cost is due to the massive complexity of the system: every party involved - and there are many - wants their cut, and they don't necessarily contribute to the well-being of the patient or the efficiency of the process.
So a $80 million yatch can't afford an $3000 high quality gyroscope?

Now you could buy amazing laser gyroscopes, for planes the Inertial navigation system error could be great, but for ships(that move more than 20X slower) is not.
I would hope the engineers designing the drone would NOT fall back to the unencrypted channels precisely because of spoofing attacks. I would think they would rather have the drone use inertial guidance to get it to a friendly area where its secrets would be safer. It may not be able to land without GPS but it would have prevented it from falling into "enemy" hands. Perhaps even activate a self destruct mechanism(s).
As it stands, the description is quite vague. It might be better to increase the focus on what you feel is the unique selling point of this community, and de-emphasise the stuff that you can do in lots of other places (e.g. share code).

Also, you have a couple of typos and grammar errors on the front page. This isn't a big deal, but it detracts from the feel of a serious project. I'm at work, but if I find time later I'll send you a pull request with some corrections.

This is literally going to ruin someones picnic.
Also, most of the ATL companies are bootstrapped and there is no cultural of handing out liberal stock options.

Valley startups don't hand out liberal options, not anymore. Typical for a 20th employee is around 0.05%, which rarely makes up for what's lost by taking a below-market salary. (Plenty of Tumblr employees cashed out with less than a million.) Almost no one going into the VC-funded world now is going to get rich enough to become an angel investor. That ship sailed about ten years ago.
Why Startups Often Beat Google and Facebook: The Science Of Small Teams
If you have a bug in another application on the server running the cache that causes it to grow its memory use, your cache would suddenly disappear/underperform, and the failure could cascade on to the system that the cache is in front of. If instead you let the offending program crash because the cache is using regular memory, this would not happen. Just a thought.

Minor contributor here: we've been trying to recruit help from HN multiple times with no luck. /g/ recognizes that the dev talent on the web resides here, so if you have a mastery of any of the needed skills (C, GUI design) we'd love your help.
Actually I'm staying in a Victorian country town called Castlemaine where there are two supermarkets under the IGA franchise. There are no Coles or other supermarket competitors here that provide the venue for a 'supermarket war' as its described. I can assure you that the prices I quote are accurate. I'm also fairly confident that the shelf price for ordinary refined flour white bread would drop significantly if there were competitors.

Cheaper options are available in a regional city called Bendigo some 35km away, and I've no doubt that there are even greater discounts available in larger cities.

And there's the rub. Lack of meaningful competition in many sectors in Australia leads to a kind of price rorting, as I believe it's called by the Australian consumer and competition agency.

I have no political axe to grind. I'm merely on the one hand pointing out a price differential observable to any visiting european, and on the other indicating what seems to be an effect of limited competition.

Australian prices generally have increased greatly relative to the English pound in my experience. The reasons for that aren't that difficult to understand, and ordinary supply demand leads to large regional variations I'm sure.

Australian politics are not my politics, though I presume they're yours. I hope I haven't stumbled into some local political schism.
Maximizing the Value of Investor Referrals
It'd be nice if the "political" stories were confined to discussing the code+philosophy of privacy and Internet freedom. But the majority are puff pieces or knee-jerk outrage articles that contribute very little to the overall discourse, except to fan the flames.

There are tons and tons of ways to discuss privacy and security in ways that are topical to Hacker News. Tools, methods, counter-measures, threat models, secure protocols, best practices, crypto, anonymization, companies and startups engaging in such, etc etc etc. These are topics that HN's core audience can engage with, while still being relevant to current events. Even the legal stuff (FISA and warrant compliance, legality of wiretapping, etc) is interesting, especially as it relates to our startups and the companies we deal with.

There is an argument to be made that surveillance/wiretapping programs require a political/legislative fix, not a technical one. But on the whole, I'd prefer that discussions involving the minutiae of such (and the events which propagated them) not be conducted here, at least not in recent quantities.
Playing with groupcache
I do some work with undergrads who are interested in startup stuff, both at a modestly prestigious private institution and a commuter public university. Data points I have are drawn from several 3DayStartup events, hackathons, daily interactions in labs, and working as a technical mentor to a few teams trying to make a startup. Some observations:

- The technical know-how varies widely among teams in undergrad, and web technologies seem to be somewhat ignored at the prestigious school: though they are slowly getting better coverage, the fact is that the curriculum is really better for more traditional computer-science topics and things related to systems and computer engineering. The commuter school offers somewhat more vocational training (MIS/CS/ITish stuff not so theoretical), so the webdev talent there seems a bit higher.

- The commuter school seems to have a bit more business hustle than the prestigious university. The students there seem to instantly grasp that revenue is an important thing, and have ideas which would appeal to the mass market a bit better. Conversely, for the really hard technical problems (not webdev stuff, but hard engineering and systems and math) the university students have an edge.

- There are way, way, way too many teams (mostly at the prestigious university) that seem preoccupied with solving problems that only apply to affluent college undergrads. Worse, many ideas are adaptations of research or design projects which are "Let's build this thing cheaply for the third world", and they lack the skill (usually) to explain why that would be a lucrative investing opportunity.

- At the accelerator for the prestigious university (now finishing its first summer round) some of the undergrad teams seemed to have trouble making the mental shift from "this is a school project like all the other ones I've done before" to "oh god this is a real business there is no rubric to follow i need to start hustling".

I'd be interested in hearing what others' experiences are doing similar work. I suspect that areas (say, Stanford, MIT, etc.) with more VC background probably have much different cultures.
That would only work if it had a really silly default similar in a way to "automatically connect to available Wi-Fi network" even when it's unsecured. It's possible the manufacturer may have overlooked something like that, but if it is in a military capacity, I doubt they would have left a gaping hole like that. Electronic countermeasures have been in use for several decades now so jamming/hijacking etc... would have been considerations in the design and they may have introduced hardening against those.
Actually, to get acceptable results even when converting from RGB to grayscale, you must weight the components unequally. See, for example, https://en.wikipedia.org/wiki/Grayscale#Converting_color_to_...
The first reply in that post tells that - "Essentially every image is nothing but a matrix of numbers, right? Numbers in the matrix can denote several things. For B/W image, these can be grey scale numbers from 1 to 255 (1 being the White and 255 being the Black). For colored images, each entry in the matrix can be a vector of (Red, Blue, Green) scales, since every color can be represented by these three basic colors.

Now, when you want to produce any effect, essentially you need to do some operation on this matrix. For example, if you want to remove the high contrast (sudden change of color from white to black), then you need to remove the high frequency components from your matrix. Taking a Fourier transform and removing the high frequency components and taking back the inverse transform can do the trick for you. I'm not sure about Sepia effect in particular, but all I want to convey here is doing some operation on Matrix does the job. Hope it helps."
I don't think you read the source code. At all.
Maybe not, but that's why online and software based learning needs to be made exemplary. Teachers should be pooling their notes and putting together scripts that people with excellent charisma can execute on camera. Casually filmed lectures will rarely if ever be as inspirational as a powerful teacher can be face to face, but high production movie-like videos might just stand a chance.
yes that was precisely my point. No sense commenting on an article if you havent read what it talks about.
Motivation is something personal, you have to find what motivates yourself. There is books on that, but I can't advise you as I never used them.

As I see it, the key for doing things is to begin, then to focus. Can't focus ? Do another. Just keep doing.
Motivation is not really something that helps you when you are doing, it's something that helps you to begin and to end.

But is motivation the only way to begin and end things ? Obviously not. Duty, deadlines, promises, anything that make you morally engaged in an action.
So, go set some goals ! Make it as a timeline with deadlines, make it as a flat TODO, make it as a scrumy (http://scrumy.com is a great service), try, fail, repeat until you win.

There is no way to find the good one until you tried it. So keep doing things, be amazing. ;-)
That much is obvious.
Signs of dysfunctional engineering teams
The reality is that major ISPs like Verizon and Comcast want Netflix to DIE because it is a major competitor of theirs. How many people have cut their cable TV service because Netflix is "good enough?"

So Verizon and Comcast can compete with Netflix, or they can attempt to cut off their knees.

"Nice streaming service you got there. Be a shame if it was so slow your users got frustrated and cancelled their service."

This is why Verizon and Comcast don't take Netflix up on their offer to provide caching servers, create peering agreements and take other actions that actually decrease the ISP's cost. Because Verizon and Comcast want Netflix DEAD.

He does have a point, though. Lifehacking was supposed to be a means to an end: a way to get more time to oneself by finding more effective ways to deal with the daily chores and other "maintenance" tasks. But for far too many, it has become an end and itself: the time gained back from lifehacks gets reinvested into LIFEHACK MOAR, and we become slaves to routine in the very way we were trying to escape. That wasn't the point.

What lifehacks are awesome for, though, is getting your life straightened out. If you're like a lot of geeks, you can probably identify one or two things that you've let fall by the wayside in the quest for more time that you really shouldn't have. But now, you're having more trouble Just Doing Them back into your life. Lifehacks present an alternate approach to these tasks: a way to do them that breaks the psychological associations that led you to stop doing them in the first place. That can be a very powerful thing. So next time you decide to tackle that task, try a lifehacked approach. It really helps.
The author and teacher of this course, Brent Yorgey, is one of those rare guys who is both a fantastic lecturer and a fantastic researcher.

Georgia Tech was a mixed bag during that period if I remember correctly. I fought to keep the ACM chapter relevant to encourage entrepreneurship from 2002 to 2004, but it didn't quite stick way I had dreamed.

The research going on at Georgia Tech is amazing. But its hard to build a startup out of that culture - especially a consumer internet one.

But the best opportunities are usually hard things.
For me, the motivation comes by having other people use and respond to the software I create. This means getting out of my developer bubble and doing some marketing. When people are engaging with your creations in a positive way, it's hard to not be motivated.

I think this applies to any software product that is written with the intention of having someone else use it, open source or otherwise.
As a naive potential user I am willing to take the assurance of proper crypto and forward secrecy. What needs to be addressed also is the issue of metadata. It is the broad collection and easy analysis of metadata -- NOT content -- that makes NSA monitoring so sinister. By knowing all about who you connect with, when, for how long, and with what regularity, they can know a vast amount about you.

What of the who/when/how-long/how-often metadata is evident when using Tox? As compared to normal skype or IM, that is?

It's even worse than that. States are not only reducing their funding, but the funding they do provide is nowhere near the operating requirements for major universities. Consider my alma mater, the University of Virginia, which receives about $8500 in funding per full-time student from the state (so roughly $150m/yr). This is <6% of their $2.6b annual operating budget[1]. Compare this to the 45% of funds that comes from health center patient revenues, or the 10-11% that each come from research/grants and gifts.[2] Pretty ridiculous. Spending is out of control, of course, but even not-for-profit schools are competing against each other for talent & grants, and the best ways they seem to know how involve huge infrastructure & technology investments, not to mention extra perks for students/faculty/staff.

> often reasonably well-supported perspective

That's the part that's unfortunately often untrue. HN posters on political topics seem much less informed than on technical topics. On technical subjects, someone who's offering strong opinions while obviously not having read much background material will typically be sidelined, but in political discussions, people don't seem to feel a strong need to do background reading or support their claims with evidence.
I discussed this with my friend yesterday and wondered about key management with the military GPS channels. Is there a single key that, if extracted* from just one military GPS receiver, could spoof all military signals? Or are there multiple keys, possibly with a revocation scheme? GPS is getting old, what was the state of the art key management back then?

* I'm sure the anti-tamper technology is pretty great.
To the point of your edit, you see identical behavior on Gold investor boards in the typical sites (Motley Food, Seeking Alpha, et al). Everything is good news for gold. If "A" is good for gold, so is "!A". This money flowing in to ETF, inventory levels, chart technicals... almost anything. In the event that something is difficult to justify immediately as good news, it is the product of a malicious conspiracy (market makers, central banks).

I'm only comparing the group dynamic and the hostile reaction to any suggestion that triggers cognitive dissonance. I haven't checked the chart on Mt Gox in ages, last I saw 1 BTC was ~ 125 USD. As a disinterested observer, this Thailand development doesn't seem very important one way or the other, but it's hard to interpret as positive.
As usual, /usr/games/fortune provides some insightful commentary:

"On the other hand, the TCP camp also has a phrase for OSI people. There are lots of phrases. My favorite is `nitwit' -- and the rationale is the Internet philosophy has always been you have extremely bright, non-partisan researchers look at a topic, do world-class research, do several competing implementations, have a bake-off, determine what works best, write it down and make that the standard.

The OSI view is entirely opposite. You take written contributions from a much larger community, you put the contributions in a room of committee people with, quite honestly, vast political differences and all with their own political axes to grind, and four years later you get something out, usually without it ever having been implemented once.

So the Internet perspective is implement it, make it work well, then write it down, whereas the OSI perspective is to agree on it, write it down, circulate it a lot and now we'll see if anyone can implement it after it's an international standard and every vendor in the world is committed to it. One of those processes is backwards, and I don't think it takes a Lucasian professor of physics at Oxford to figure out which."

Its nice if you can use groupcache as a memcache replacement even if some use-cases tie the hands of the implementation e.g. replication of hot items.
Well, you could say the same about a non-religious person. Tell them about God, and they would flat out deny it. Why? Because they believe their own worldview to be correct, and that God is incompatible with it. It's fair for them, so it should be fair for religious people to do the same. To them, religious reality is as axiomatic as scientific fact is to non-religious people. It doesn't matter which side is technically correct - they both believe their own point to be true, based on the very complex cultural and social factors in their upbringing. I don't think a religious and non-religious person are physiologically any different, they just make different choices about their beliefs.

I'm not saying science is equivalent to a religion, but rather that a religious worldview is just as unshakable as a non-religious worldview.
It's interesting to me that #5 indicates the price was $100. I look at the site 4 hours later and the price has dropped to $49, with little to no indication that this is an introductory price, more like a permanent price drop.

This affects me in two negative ways, in addition to the others that onion2k mentions. One is that you haven't properly vetted what someone is willing to pay for your services and two, you don't give a shit about your paying customers.

Say on the off-chance I signed up for your service 5 hours ago at the $100 rate and 5 hours later, you change the rate to $49, would you automatically refund me 50% of what I paid you? Would you hope I didn't notice? Would I be shit out of luck? Would I have to bring it to your attention?
Yes, when the underlying assumptions don't change and the program is already good it will remain good. The point is that the changes of the underlying assumptions can make even the once perfect program one that's suddenly unusable and it's impossible to cover all future possibilities. Targeting realistically is the only way to make the good program at the start.
> The analogy between bridge building and software is very old and very wrong.

I disagree. I think that the assumptions and use cases just change much more quickly in software than in the physical world.

The covered bridges from 150 years ago were built with the assumption that they'd be used for horses, carts and people. When cars became the primary mode of transportation then those assumptions no longer held. No one would say that the original bridge was poorly built, just that the use case changed.

Similarly, software that was built with the assumption that network access is slow has had its typical use case change. Software that was built to keep things on disk because RAM is expensive needed to change. Pretty soon we'll all demand that software assume that disk access is fast again because we'll move to SSDs.
