I've been thinking about this for a while. I've wrote some thoughts I had over the years about modernising Lisp.

I'm posting this, because I'm curious about what the Hacker News readers think about it and I want to read a better discussion larger than 140 characters...

Because it would be very hard to find a collision of a file that behaves exactly like a ZipFile.

To make a collision work, you would need to inject the payload into the program, and find a specific blob to put into the zip file, that once compressed and hashed would cause a collision. This isn't computationally efficient.

I dabbled with implementing Swift on JavaScript, but has proven a bit difficult. The grammar is very big and just implementing a parser is huge task on its own.

I would like to see someone tackle this though.

Doesn't dokku does this already? I mean, I've tried dokku and my experience was quite similar to heroku.

This is Apple making an attack at Google. Microsoft is a gonner in a few years. Google was ready to take charge of their market with Google apps and cloud services.

Apple is gonna make IBM build a cloud base infrastructure with Apple User interface and QA. We are talking very high end costumers, not the typical small or medium corp. No one will be fired for buying Apple and IBM. Google, maybe.

Enterprise Cloud was one Horse race for Microsoft market. Now there are two.

I tried to launch something similar (http://intigos.com).

The problem is that Google launched something that does pretty much all that, and is integrated in their Google play games.

I've never tried Canvas, but from what I could gather it seems it is just a LMS. FenixEdu is a combination between a Academic Management System and a LMS. It has course pages, but also manages the diploma emission, teacher credits, room management, scheduling, Erasmus, etc. all the other backoffice stuff a school has to handle.

FenixEdu has been in use for the last 10 years, and in continuous development over that time, so I would say it its mature.

It didn't started as a LMS, actually started as a Academic Management System. We needed a system to control all the academic administrative operations. Later we developed the LMS system connected with the AMS.

Right now we are on the process of replacing our old LMS with a new one. We have very cool ideas that we are developing right now (timeline based view for the students, tools for interactive presentations, transparent support for MOOCs, etc.)

If you want to start the system, take a look at this one http://fenixedu.org/dev/fenixedu-bible.pdf . We finished it last week, its just draft, but might be also interesting, particularly if you want to test the system.

Shameless plug, I'm a member of FenixEdu, a open source academic and learning management system. I think that people might find it interesting.

FenixEdu was designed for a single school for the past 10 years and now we are trying to refactor it to be installed anywhere. We want to create that can tackle the needs for the next decade of teaching. If people are interested in this kind of thing please talk with us, we are most welcome to receive any kind of suggestion or feedback.

I have a feeling this guy is going to appear somehow, somewhere in the Portugal Telecom / Oi merger.

Does anyone have the theoretical description of what is happening? I'm curious about the fractal patterns being generated and the increasing in entropy and the that results in a catastrophic failure of the stable system. Is this some kind of chaotic system or is just an force field being applied on the particules.

Since I bump into one of you guys in the Startup Lisboa elevator I been thinking about your startup. As a concept is cool and sounds great but as an actual product doesn't work.

First of, market. Not there isn't a market for computing power, but a market for this kind of thing. This is a good parlour trick, to show of browser power, but as a computational framework it doesn't work. There are far better and cost sensitive solutions, even using the cheapest AWS service. I know, because I did the math.

Second there is the ethical problem. You are are off shooting the cost of cloud computing to the website client that will pay for the extra electric power generated by your tasks. How do you justify that? More so, how can you justify a ecological minded person paying for mapreduce geological data from oil company?

Third, and the one that kills you, security. You cannot assure the confidentiality of the data being processed. You can not use homomorphic encryption because you do not know the operations you need to do on your data, and since you are working over it, at least in memory it must exist in plain text. Therefor you cannot assure your clients data confidentiality. Worse, this screws up the market fit. The only people that have big data needing to be processed that isn't confidential is research institutions. The thing is, research institutions buy computer power by the stack. I know, I work at one. There is always some grant that allows them to buy a bunch of computers to do parallel processing.

I've heard about you guys for over an year. And it took you more than a year to complete the full product to launch it. What have you been up to? I've seen clones of your product on techcrunch 500. I made a clone of your product using bitcoins, in a weekend. (I did the calculations and wasn't cost effective and I decided not to launch it) Where I work, Técnico Lisboa, we are actually thinking about deploying my clone in my work, over computers we own and provide that computing power to the faculty. Actually I've seen this in 2009, when it was shown of by Ruben Fonseca on Codebits (http://blog.0x82.com/2010/11/22/map-crowd-reduce). If anyone can do this, how can you assure the competitiveness of your product.

No. Removing cork only removes the outer layer of the tree and doesn't harm the tree. 9 years the cork is removed (and it must be removed or the cork goes bad) and a new one grows uup.

Unknown also to most of you Cork is such a lucrative buisness that cork removing is one of the most lucrative jobs you can find in rural areas. During the harvesting seasion, many removers can make money for the entire year in a month or two. however the job is excruciating because of dust and weight. Trees owners also make lots of money.

Yes, better wine preservation.

Although off topic I have to share this. I actually came from coruche, that is a small village in the middle of Portugal and is so cool to find an article in hacker news about it! :D

I think it looks awesome, it really does! However twitter bootstrap looks really generic therefor can be used any place, Fbootstrapp looks a lot like Facebook and cannot be used for much else beside Facebook apps without looking like a rip off.

They removed "Most Recent". That's the only thing that I use, and most people use on facebook.

I don't like the change, but if they are competing with google by making drastic changes to their interface, then they have a problem.

Its not a new feature that people don't like, the interface is completely diferent, and unsable!

Why the hell do you think i want one so badly?

@notauser Yeah, but I have to write my thesis until January 7 and I need to focus on that for now.

To answer you:

1) No. This was just a hacking solution that I got. ECMA already has a solution but browsers haven't implemented yet. When JS engines start implementing ECMA class system, JSC will became obsolete.

2) I looked to ES4 and 5 spec, but they were too extense. I wanted something more simple, that could be similar in syntax to Java-like language with some flavours of SmallTalk. My main problem was with code from the same class being scattered on several files. This led me to creating the same classes and packages concepts that exist on other languages. More so, if you never code in JS before, this syntax seems more friendly than some weird new object system.
