  • Jumblesale: A better platform for selling your stuff

    Selling your private stuff has become quite tricky lately, in contrary to ( fill in any web-related stuff here ). It was always my intention to sell things i don't need any more in a simple way somewhere. In a simple way. I just can't consider eBay simple. I don't want to create fancy custom-layouts. I neither want to read through one's comments to find out whether he or she is a black sheep or not. 

    Well, long story short, I had an idea ( once again ). I want to build a simple platform that supports especially the blogging people in selling stuff. Why blogging people? Because a modern system would best integrate there, i guess. 

    I named it jumblesale, and I'm going to specify what it's good for. The intended audience is people who occasionally find stuff they don't have use for anymore and want to sell it, e.g. a TV-Set or an old iPod: Non-Commercial and for private use only. This is to ensure that the focus is not on competition but on selling. This is also emphasised by choosing NOT to allow auctions. I just don't want to place my 3g-iPod on eBay for a starting bid of 1€. I want to sell it for 120€, and whoever wants to get it for that money, simply can. 

    By building the system in a way that supports RESTful access, it can be easily used from outside systems and integrated into blogs, widgets and more useful places. 

    I also decided that the eBay of rating sellers isn't the best, at least not for a small marketplace. I always liked the idea of having a circle of trust, members that guarantee for each other. So each new member requires to have an invitation to sign-up, and a higher count of "friends" at jumblesale will increase ( hopefully ) the trust buyers have in a seller. There is no plan to combine it with other features of a social network, such as messaging and so on, but the friend feature is very useful in this context. Maybe conflicts may be easier resolved by a social pressure forcing a seller to act properly.

    Right now I'm exchanging my thoughts on this topic with a friend of mine, Sven Pfleiderer, and we'll maybe handle this as a project for our studies. You can read his blog here

  • The dying MacBook: Early adopters fate.

    So it is. I have a MacBook, the beautiful ( at least it used to be ) white, 13" screen, first model. But as with any living being, death is certain and signs for its arrival are mostly undeniable. Would my MacBook be a human patient, he would be approaching multi-organ failure. But let's step over to the comprehensive list of failures.

    Bluetooth seems to work only when Moon and some other planets are in a constellation allowing certain, yet to be discovered, microwaves to be sent to the outer world, thus enabling bluetooth. I can assure you that this planetary constellation is indeed very, very rare and so is my bluetooth.

    I wouldn't bother just because of a broken bluetooth device, but fun is that one of the two USB-Ports seems to have been infected by the same disease little Bluetooth already has. Random failures. Just random.

    There are days when I just don't care about these little details. Its the days when the display starts to flicker. I'm not the only one ( the above reported issues are also well-known ), as you can see here. I'm glad to have a external display allowing me to take back control - and actually see it!

    That's it? Nope. Battery life is over, okay, no comment here, just normal. But case life too? Actually its broken in two places, and it appears to me to be just lousy. really. I'm quite confident though that it won't happen with a new Alu MacBook, which I'm going to buy as soon as I find out about my fathers credit card number. Any hints welcome.

    Good night.

    Update: After I posted this here, my ComboDrive began making strange noises. And hasn't stopped doing that since. Hmlz.

  • Pass-by-reference workaround in Java

    As anybody knows, java passes variables by value. and i haven't found the magic compiler switch to change that. of course, there are problems caused by this restriction, but in most cases, pass-by-value works just fine. 

    If you end up in a situation where it'd come in handy to have a pass-by-reference facility, think about the way java is storing objects, and how these objects are then passed-by-value. 

    First of all, an object variable contains only a ( typed ) memory address. Thus, comparing e.g. two strings for equality will yield only true if they are in fact the same strings, same applies for all other types. And this is the value. So in fact you pass a ( kind of ) pointer to a function, enabling to manipulate the original object, as the object is not cloned or something else.

    Its also common to encapsulate basic types like int into a object just for the sake of manipulating it in some methods.

    So let's break it down to a simple example:

    class MInt {
    	int x;
