Ask Slashdot: Tools For Teaching High School Kids How To Make Games?

andi75 Scratch ( (237 comments)

Check out It sure looks like kiddy stuff at first glance, but its awesomeness cannot be described, you have to try it yourself.

Since scratch takes care about all the nitty-gritty details, you can focus on actually *designing* good games, which is awfully hard.

Franken Bill Would Protect Consumers Location Data

andi75 The *consent* will be buried in the EULA (90 comments)

Asking for consent is absolutely meaningless. In order to get security updates, you'll have to accept the new EULA and will be forced to agree to whatever they ask.

The only way out is to make it illegal to store any more data then is absolutely necessary (e.g. a train time table app only needs your location *now* to find the nearest station, but has no business of retaining that data) for the normal operation of the application.

What Does IQ Really Measure?

andi75 Re:Your Intelligence Quotient. (488 comments)

Actually, it is quite correct. But it's also inefficient. Better is:

14 * 16 is (15 - 1) * (15 + 1) is 15^2 - 1^2 and since you probably have all the square numbers memorized anyway (yes, those tables ARE useful), so 15^2 - 1 = 225 - 1 = 224 comes easy :-)

Garry's Mod Catches Pirates the Fun Way

andi75 Re:Not a new idea, and not a good idea. (365 comments)

> I don't see how you can say that this piracy detection fails occasionally. What is your reference?

Some games refuse to install when CD emulation software is installed on the computer. Some games refuse to run when the CD has minor scratches. Some games refuse to run if they can't reach the authentication server. Some operating systems want to be 'reactivated' when they detect one too many hardware changes.

I don't know enough about Steam to tell you where its failure points are, but it's far from the only DRM system in town.

If, in any of those cases, the software stopped throwing an error (which is already quite annoying) and instead started to sabotage me quietly, I'd consider legal action.

Garry's Mod Catches Pirates the Fun Way

andi75 Not a new idea, and not a good idea. (365 comments)

The piracy detection fails occassionally, and a honest paying customer gets hurt (and probably buys less in the future, because he feels (and rightly so) that he got cheated).

Europe Plans To Ban Petrol Cars From Cities By 2050

andi75 Re:To expensive (695 comments)

> Google lightbulbs and mercury and see that the result comes at a (possible unacceptably high) price though.

After following my own advice I come to the (certainly not expertly derived) conclusion that the benefits far outweight the drawbacks..It'll probably turn out very similiar for the electric vs. petrol fueled cars...

An Interview With C++ Creator Bjarne Stroustrup

andi75 Re:Interview (509 comments)

There are certainly a lot of competent C++ programmers out there. But there's also a lot of less competent ones. And sometime you get one who appears to be compotent, but actually isn't. With C++, these guys can do A LOT MORE damage to your project than they could do with simpler languages, and after a few years, the project becomes an unmanageable mess that's far more expensive to maintain and extend than it should be.

Tevatron To Shut Down At End of 2011

andi75 Re:Modern world has its priorities wrong (260 comments)

I think it was the famous 18th century mathematician Laplace who once said "there is no military application for number theory", and less then 150 years later, its applications (cryptography) where probably one of the deciding factors for the outcome of World War II.

I don't think we can rule out that high energy physics will give us cool stuff to play with eventually.

Mac OS X 10.6.6 Introduces App Store

Actually, some people (e.g. me) already removed the CD/DVD drive from their Macbook Pro and replaced it with 2nd harddrive (because the primary SSD is maybe a bit small, especially if you're using Bootcamp as well).

So far I'm doing just fine (I even bought MS Office as a download).

Browsing the Body

andi75 Generally awesome, transparency sucks though. (107 comments)

While I think this is awesome, and biology teachers all over the world will love it, the transparency rendering is quite terrible.

The problem is that some surfaces are rendered, while others are not, which looks very wierd. You can reproduce the effect by only displaying the skeleton and setting transparency to 50% or so.

There are two generally accepted solutions:

1) To a topological sort and render all triangles back to front
2) Use a so called depth-peeling algorithm to render the scene in multiple passes

Unfortunately, they do neither right now, but there's always hope for the next version.

Personally, I favor 2) since you can offload all the work to the GPU. I had to implement this once for a CAD/CAM system for hearing aids (they are often custom-built, and you want to render the exterior semi-transparent so you can place the battery and electronics inside perfectly, before sending the thing to the manufacturing machine).

Xbox 360 Jailbreaker May Need Real Jailbreak

andi75 Think of the children (359 comments)

Believe it or not, but I'd love to mod my Wii so I could create & play backups of all the discs I bought, because I don't want buy them again when my kids accidently scratch my Mario Kart discs when they play them.

And I'd gladly pay someone for the service too (after all, he's spending time, and he's risking to brick my hardware, so there's some liability as well...).

The only real solution is to pass a law that makes all kinds of DRM illegal. Any technology whose only purpose is to make the usage of the product more difficult and cumbersome (yes, that includes unskippable DVD ads) should be banned.

Thief Returns Stolen Laptop Contents On USB Stick

andi75 Re:Same in Germany for wallets (352 comments)

Noone asks for IDs because every purchase requires you to enter a PIN number (even with credit cards these days, not just debit cards). So unless you write your PIN on your card, you're quite safe.

HDCP Encryption/Decryption Code Released

andi75 Re:DRM is so costly, it should be forbidden. (225 comments)

While I think most of the original post is pure trolling, this line got me thinking...

> Think about it. If it wasn't for the cameras and security guards wouldn't you be stealing from stores?

No, I wouldn't. First, I haven't seen any security guards in the stores in town all (and only few cameras, mostly in the big grocery stores). Also, about half the farms around here are selling stuff (milk, eggs, vegetables, jam, cheese, etc.) without any security measures at all. It works like this: You enter the store room, grab what you want, write it down on the list, and put the money in a jar.

The big game demos are back.

andi75 (84413) writes "The big game demos are back. Mafia II, Metro 2033, R.U.S.E and also Starcraft II (if you get hold of a trial key) all offer try-before-buy again. It looks like publishers changed their minds since the publication of this pcmag article."
