Unreal Engine 4 Launching With Full Source Code

downix A smart move for Epic (149 comments)

Epic's terms for 4 are quite affordable, that's why we made the move to 4 from three for City of Titans after our Kickstarter last year. These terms are very positive for those seeking to deal with a top end game engine which is, simply, a joy to work with.

Unreal Engine 4 Launching With Full Source Code

downix A bit misleading (149 comments)

That is per-person involved in development. A 1-2 person team, sure, no big deal. A 300 man AAA, no thank you.

Should Congress Telecommute?

downix Re: Yes! (213 comments)

You do realize that the budget is a meaningless piece of paper holding no authority, yes? Spending resolutions are the real thing and the Senate has passed those. Why waste time on hollow gestures with no authority?

NASA Taps 7 Commercial Firms For Suborbital Flights

downix Re:what a joke.... (27 comments)

NASA does many such contracts on a regular basis. This is for suborbital research, commonly done on vehicles such as the Black Brant and Terrior, a class of vehicles called Sounding Rockets. Several small companies have stepped forward with new suborbital programs which cost far less than these older systems, such as Scaled Composites SpaceShipTwo, Blue Origin's New Shepherd and the XCOR Lynx, and the old contracts expire next year, so this is the right time to gather replacements.

The last contract setup cost us $4 million, but was in 1998, so with inflation in place, $10 million sounds about right.

New NASA Data Casts Doubt On Global Warming Models

downix Check the sources (954 comments)

The article in Forbes is written by a fellow for the Heartland Institute, one of the numerous front organizations for the coal and oil industries alongside other such groups as "CO2 is Green". The study is not peer reviewed, it has been published *for* peer review, there is a dramatic difference between the two. Beyond that, you have the issue that the study argues 180 degrees opposite to the articles claims. In short, the article is complete bunk, written by a fraud with an attempt to reinforce the positions of those who wish to kill scientific progress and research.

NASA Pitches Heavy Lift Vehicle To Congress

downix Re:Frankenstack (275 comments)

He's not the only person, or company, with heavy lift designs, and many of those involved have a longer track record. There are, in fact, 13 companies now submitting heavy lift designs now. Boeing's proposal is already relatively well known, as is SpaceX. But I am curious what Orbital is proposing. They are, after all, the operators of more models of launch vehicles than any other company out there (having 6 operational rockets at the moment) and the engines on their upcoming Taurus II happen to have come from a previous Heavy Lift Vehicle. (literally, when it was cancelled, they yanked the engines off of the 4 units which hadn't been launched and mothballed them. Refurbished, the engines are now the powerplant behind the Taurus II launch vehicle)

No, they're not, and no, they can't.

You instead may be referring to Hybrid rockets, solid fuel, liquid oxidizer. Those can, yes, be turned on and off, and are quite efficient.

NASA Pitches Heavy Lift Vehicle To Congress

downix Re:A Bit Left Off (275 comments)

Aerojet, the other solid rocket engine company, warned of this in the 1960's. They built large single-piece solids, including the most powerful rocket engine ever built, the mighty AJ-260-2. The AJ-260-2 was part of the evolved Saturn program. Stage 1 of the Saturn I would be replaced by this one, huge, solid rocket motor. This would reduce the cost to operate the unit dramatically it was felt. After Challenger, they again offered the skills to manufacture the single-piece solid, but were rejected.

Incidentally, the AJ-260-2 is still sitting in Florida, all but forgotten in an abandoned warehouse.

Unfortunately, those solids are *not* the same as the shuttles. New formula, new machine tooling, new design. They re-use the casings only. The rest of it, an all new SRB design. Oh, and they got rid of the old tools, so they can no longer manufacture them. Handy trick wouldn't you say?

You just pitched the case for Ares I. Of course, that ended with a launcher which was incapable of lifting the Orion Capsule, or anything else.

downix Re:Let's get this straight (275 comments)

The name Ares V pre-dates Constellation, actually. It was attached to the ESAS study, which produced the Ares V, and of which this rocket is a carry-over from. Ares I was added later on in the program. This may well be called Ares, who knows. This is not a new design, it is something NASA's kicked around, in one guise or another, since the 1970's.

downix Re:What, this is nonsense (275 comments)

The RS-68 is not capable of being used in manned flight. It lacks the safety features to tell the flight control computer "Oh shit, we're about to blow up!" If the computer doesn't know soon enough, one accident and your astronauts are deep fried spacemen.

In addition, NASA had a program for throwaway SSME's in the late 1980's/early 1990's. The technology for doing that is still there. They would ressurect this plan, removing the reusability from the SSME entirely. Makes them almost as cheap as the RS-68, and are far more capable. Less thrust, more isp. And once out of the atmosphere, isp is king.

downix Re:Why Must NASA Develop a Launcher? (275 comments)

Not true, there are two other systems which can match, or surpass, Ares V:

Energia Vulkan, a 200 metric tonne version of their Energia rocket.
Atlas V Phase III, which is fundimentally a US version of the Energia.

downix Re:Falcon XX (275 comments)

The Russians had a better solution than the SRB's, LRB's. I refer, of course, to the Energia Vulkan. It is an Energia rocket, the one they used for their shuttle, the Buran, but with 8 Zenit boosters, rather than just 4. It could deliver almost 200 metric tonnes to orbit.

If you use LRB's, the weight savings and flexibility would enable you to make a scalable solution. Energia, for instance, could scale from 20 metric tonnes to the gigantic 200 metric tonnes, all using the same parts. Even the LRB's are used as standalone launchers by Sea Launch. Our Atlas V and Taurus II rockets both use elements borrowed from the Energia system.

Here are pictures and information about the Energia configurations:

downix Re:Falcon XX (275 comments)

Not quite. Ares I's shortcomings and ultimate failure had forced Ares V to carry more and more of the load for the mission. This required re-designing it, again, and again, pushing it upwards and onwards, new first stage engines, then new SRB's, then new upper stage engine, then new tank, than new first stage engines....

Being able to kill Ares I, they could return Ares V back to the original, much more affordable version. This is the original Ares V, before Ares I's issues began to mess with it.

downix Re:Let's get this straight (275 comments)

Thiokol is now part of ATK, and Constellation was their baby. They destroyed the Shuttle SRB tools before requirement in order to push the Ares one forward. Unfortunately, ATK has Senator Orrin Hatch in their pocket, and he's a stubborn old mule.

There are designs which do away with the SRB, I'm helping out with one myself, but the political lobbying power of ATK is insane. Their SRB production line is a full 0.5% of Utah's GDP, and Senator Hatch is not one to let that go. With the ICBM's gone, they would loose their large segmented solid business entirely. Aerojet, the other SRB maker, saw this coming in the 1960's, and migrated everything to non-segmented solids (they also have the record for the worlds most powerful engine, a solid rocket engine called the AJ-260-2 if you ever want to look that up). There are still solid motors, but nobody else in the US uses, or makes, large segmented solids. Only France also makes large segmented solids, for their Ariene V launcher and their own ICBM's are rumored to use the technology, but nothing is known for certain. And the Ariene is due to have those removed for the Ariene VI and replaced with flyback, liquid boosters.

Falcon 9 can't carry Orion. Too heavy.

Delta IV Heavy can carry Orion, but we're back to the no man-rating for the rocket. In addition to the engine, ULA lists 18 other major changes needed to bring the rocket up to safety standards.

The proposed Atlas V Heavy could do it as well, and it is already man-rated. But it uses a Russian engine, so a political non-starter unless you start domestic production.

Amiga clone-OS MorphOS releases revision 2.0

downix downix writes  |  more than 6 years ago

downix writes "For those that remember, MorphOS arose a few years back as an Amiga compatible operating system for Amiga systems with PowerPC accelerators and a few PowerPC motherboards. After years of work, the release of MorphOS 2.0 has finally come, an accomplishment for the very dedicated team of developers behind it. The release notes can be found here and there is a time limited demo for those of us with systems able to run the OS.

Will this bring back our favorite pre-Windows platform from the grave? Likely not, but it is a fun little system to play with and enjoy."

AMD raises the stakes in integrated graphics

downix downix writes  |  more than 6 years ago

downix writes "PC Magazine is reporting that AMD will be releasing two new chipsets. What makes the new 780V and 780G interesting is that they will be incorporating full R620-based graphics cores, giving the new chipsets onboard graphics performance equivelent to entry level graphics cards. This is a new strategy for AMD, and only time will tell how successful it is, but when combined with the opening up of the GPU specifications, the options to utilizing this core for GPGPU work while utilizing a regular Graphics card makes this move very interesting."

Open Source Amiga clone pricing announced

downix downix writes  |  more than 6 years ago

downix writes "For those who have not been following, Dennis VanWeeren created the first cloned Amiga hardware earlier in 2007. Up until now, the only way to have one of these MiniMigs was to build it yourself, not an easy task for all people. But, ACube systems, the guys developing the SAM440 PowerPC motherboard, have stepped up, making available a fully assembled Minimig for the cost of 138 euro. The idea of having your own, brand new, Amiga is exciting to some, but a full open-source hardware platform should be exciting to all of us."

Duke Nukem Forever Traser Trailer Released

The 4th installment of the popular gaming franchise has been under long development, and has been listed as vaporware for going on a decade. I guess this means that I'll have to retire my "will it ship with DNF" jokes in regards to the Amiga then, won't I?"

Sun Niagra 2 CPU now open-sourced!

downix downix writes  |  about 7 years ago

downix writes "Late last night Sun Microsystems announced the immediate availability of the UltraSPARC T2, also known as the Niagra 2 CPU. While we all might not have a silicon fab in the basement, the access to this source code reaffirms Suns commitment to open source, and in addition gives us FPGA-lovers something new to play with. The source code can be downloaded (with registration) from here. Already the previously open sourced T1 has spawned spin-off projects, such as the Simple RISC S1."

Amiga clone OS now 64-bit

After seeing the almost laughable progress of the actual OS, witnessing the progress under a peer-reviewed and open-sourced from-scratch reimplimentation is a breath of fresh air. While still incomplete, AROS has had remarkable progress, and shows promise for the future."
