Titanium-Headed Golf Clubs Create Brush Fire Hazard In California

Gibgezr Re:Aluminum (169 comments)

No, the metal and composite heads are already made hollow. Titanium has a better strength vs. weight ratio than most other materials they could use. Its alloys also have useful "hardness" and "ductility" (elongation) properties when making heads for golf clubs.

So no, it's not used for its name, it's used for its performance.

Daylight Saving Time ...

Gibgezr Re:Time to lose Daylight Savings Time (310 comments)

>There's no logical argument for the time change. None.

In rural areas where children walk down sidewalk-less roads to wait at unsheltered bus stops, parents well understand the usefulness of DST. I grew up in a farming community, and it was never about the farmers, it was always understood that DST was a way to keeps the kids safe.

I am against DST, but as a rural parent of 4 I understand full well that there is at least one very strong argument for keeping it.

'Google Buses' Are Bad For Cities, Says New York MTA Official

Gibgezr Re:More than that... (606 comments)

Not really: as an example, a father of a friend of mine sold a beautiful mansion in the suburbs, and bought a crappy house in the expensive city core (near a hospital, which is why they moved; his wife was ill). He paid twice as much for the crappy house, complete with 70's era disco interior decorating.

So, yes, you can purchase a more expensive slum. Location, location, location.

Ask "The Fat Man" George Sanger About Music and Computer Games

Gibgezr Interactive music (66 comments)

Have you tried composing interactive music, that dynamically changes according to choices the player makes "on-the-fly"? If so, what technology do you prefer to use when composing for interactive soundtracks?

The first time I remember hearing highly interactive music in a game was "Shogo: Mobile Armor Division", back in 1998; they used a program that was similar to the old Amiga "Bars & Pipes" to help compose that music. All I remember is that the program was part of the DirectX suite at the time.

Care to give us the "actual" first edition's ISBN? Maybe someone could scan it and upload it...like you?

Google Brings AmigaOS to Chrome Via Native Client Emulation

Gibgezr Re:We must go deeper! (157 comments)

....and then we can run the emulator on the emulated chrome running on the emulator, running on chrome?

It's fricking turtles all the way down!

This reminds me of someone showing off his Amiga by seeing how many clock apps he could run simultaneously on the desktop. At the time we were all suitably impressed with the egregious display of multitasking of having 100 overlapping clocks all ticking away the seconds simultaneously. I would still be impressed (and entertained for at least a minute) by chrome->AmigaOS->chrome->AmigaOS->chrome web browsing.

Ask Slashdot: How Reproducible Is Arithmetic In the Cloud?

Gibgezr Re:Fixed-point arithmetic (226 comments)

>(Same with the optimization issues we covered in that class - that it can make a real difference in runtime whether you iterate first over the rows and then over the columns of a 2-dimensional array or vice versa, depending on how your software stores arrays in memory, was a huge puzzle for minds far brighter than mine.)

If you are still curious, read the short article at http://en.wikipedia.org/wiki/Instruction_prefetch, and when you come to the bit about prefetching texels, think of those texels as data coming from certain rows/columns of your array. Then think about the way a 2 dimensional array is laid out in linear memory, and whether the next few texels (array cells) is closer you are about to process are closer to the current one if they are from the same row or instead, the same column. In one case, they are going to be packed tightly together, and so will be more likely to be all prefetched into the cache; in the other case, they will be spread out over the memory addresses, and be less likely to all wind up in the cache.

As a game programmer, I attended a conference where one extremely knowledgable fellow demonstrated a crazy thing: he could insert reads into array processing loops where the read DID NOTHING with the single data element it had just read; the whole loop would run faster, though, because that 'useless' read caused a prefetch of data that would be used. It was nuts, it made no sense if you just looked at the code, but it was a significant measurable speedup.

UK Police Seize 3D-Printed 'Gun Parts,' Which Are Actually Spare Printer Parts

Gibgezr Re:Happy I live in the US (279 comments)

Just pointing out what most folks are missing: hey had a warrant, which was not based on "look for 3D printed gun parts", but on other stuff related to the fact that this guy is a member of a criminal gang.

How Safe Is Cycling?

Gibgezr Re:Loads of prior research has been done (947 comments)

How does your comment relate to the post you are replying to? It sounds like this happened in an area where separation of cyclists and cars is not practiced.

Imagine your brother had been walking instead of cycling, and then struck by a drunk driver, and the doctors told him "good thing you wore your walking helmet, or you would have died". Now do you see what the fellow from the Netherlands was talking about?

Next-Gen GPU Progress Slowing As It Aims for 20 nm and Beyond

Gibgezr Re:Not true (91 comments)

>Not totally true. Stroke/path/fill rasterization work is not supported by current 3D rendering APIs (and thus not accelerated by 3d hardware).

Incorrect. It's there, developers just aren't using it for some reason.

Uploaded.to Blocks US Visitors After MegaUpload Sh

Gibgezr (2025238) writes "Uploaded.to has shut the door on U.S. visitors to the site; it is currently telling them “Not Available: Our service is currently unavailable in your country. Sorry about that.”
Torrentfreak is speculating that this has to do with the FBI takedown of MegaUpload earlier in the week."

White house petitioned to investigate MPAA, Chris

Gibgezr (2025238) writes "Interesting "We the People" petition, asking the white house to investigate Chris Dodd and the MPAA. I expect it will get the necessary 25K signatures, but be brushed aside with "we found nothing wrong, those were legal campaign donations"."
