Mazda Stops Production of the Last Rotary Engine Powered Car

EvilRyry Re:Efficiency check (359 comments)

The displacement number in rotary engines is quite misleading. The design is so different than a piston based engine that it's not a fair comparison. You're getting more power because you're getting more power strokes per rotation. Because you're getting more power strokes, you're doing more intake strokes (more fuel). So while power/displacement ratio is better, that doesn't necessarily affect the power/fuel ratio at all.

Java 7: What's In It For Developers

EvilRyry Scala is not dynamic! (338 comments)

FTA:

A key feature of Java SE 7 is its accommodations for dynamic languages, which are becoming prominent on the JVM lately, thanks to the emergence of languages such as JRuby and Scala.

Scala is _NOT_ a dynamic language!

The End of the Gas Guzzler

EvilRyry Re:Duh. (897 comments)

A turbo 1.8L Passat isn't exactly a beacon of high mileage sedans. There are cars with engines that have twice the displacement of that engine with better mileage.

Open Radeon 3D Driver Runs At 60~70% of Proprietary Driver Speed

EvilRyry Re:So... (245 comments)

The most important part in my view is that it allows for innovation in the open source graphics world. For instance, NVidia and ATI both make drivers for X.org however neither will produce drivers for Wayland until it gains enough traction. However Wayland will never get widely used until people can actually use it, which requires drivers. Open drivers breaks this stalemate.

EvilRyry Re:How about heating and airconditioning? (324 comments)

Mine takes 28W powered, 25W on standby :-(. I put mine on a timer to turn it disconnect the power at night. While it certainly sucks to have a device sucking a constant 25W all day long, I can't imagine that it takes as much power as my refrigerator.

New Gasoline Engine Prototype Claims 3X Current Engine Efficiency

EvilRyry Re:skeptical ... (377 comments)

And what's this thing about "the engine is only suited for hybrid-electric vehicles, but that's okay. " ... what does THAT mean?

Most likely it means that the engine has terrible spin up/down times and/or is inefficient at doing them. Its best operated at constant speed, generating electricity for an electric motor which actually pushes you forward.

The Coming War Over the Future of Java

EvilRyry Re:C# (583 comments)

>but until they learn what a compacting garbage collector is Tada! http://www.mono-project.com/Compacting_GC The new GC is bundled with 2.8 and will become the default in 2.10. Mono's VM is pretty nice overall, its the GC that caused pain in long running process scenarios. Its not so much that the GC wasn't compacting either, it was more an issue because it was a conservative scanner which lead to leaks.

HDCP Master Key Revealed

EvilRyry Re:Hooray for freedom (747 comments)

Can you cite any problems Linux has had due to HDCP?

I want to capture digital output from my cable box to my computer. The cable box refuses to talk to my computer because it won't do the HDCP handshake.

New Crypto Attack Affects Millions of ASP.NET Apps

EvilRyry Not so bad after all... (156 comments)

>If the padding is invalid, the error message that the sender gets will give him some information about the way that the site's decryption process works.

This is one reason you should send user friendly error messages to your consumers instead of stack traces, stack traces can contain details that an attacker could use against you. It sounds like you're safe if you're following best practices already.

Samsung Shows Off Galaxy Tab, Android Allegiance

EvilRyry Re:Is that a non-standard connector? (189 comments)

My thoughts exactly. Just when I thought we were getting somewhere on standardizing small devices on micro USB, Samsung teases us with an awesome device with this crazy crap on it.

Samsung Shows Off Galaxy Tab, Android Allegiance

EvilRyry Re:But ... does it run Linux!? (189 comments)

You might not have heard if you have been living under a rock for the past 2 or 3 years, but Android uses the Linux kernel. Whether you can run your _own_ Linux distribution on there is another question entirely. Sooner or later, I'm sure someone will crack it if Samsung has decided to lock it down. As with most (all?) Android devices, you're not forced to use the market.

New Air Conditioner Process Cuts Energy Use 50-90%

EvilRyry Re:Well... (445 comments)

The article never mentions sodium chloride, I though that sounded a bit off when I read the summary.

The kind NREL uses are syrupy liquids — highly concentrated aqueous salt solutions of lithium chloride or calcium chloride.

An Interview With F# Creator Don Syme

EvilRyry Re:Not even going to RTFA (267 comments)

Yes. Basically Java went the backwards compatible approach and C# went the "correct" approach.

Seeing how Java is a much more mature and widely used language, the decision made a lot of sense. Companies that were using old Java stuff wouldn't be very thrilled to learn that they couldn't use generics or any libraries that used generics.

.NET on the other hand was still rather young. They could afford to ditch backwards compatibility for long term gains.

Toyota Pedal Issue Highlights Move To Electronics

EvilRyry Re:Safety Critical (913 comments)

Its not the compression ratio that gives you good engine braking. Think about it, although it may take a fair amount of energy to compress all the air in the cylinder; you get most of it back when the piston comes down on the power stroke. The exception to this is if you have an engine brake which opens the exhaust values early so the energy you stored up as compressed air gets shot out the exhaust instead of pushing the piston back down (it also makes a nice loud sound in the process).

What gives you decent engine braking in a gas engine is having to pull air past a mostly closed throttle. In diesels, there typically is no throttle so you get very poor engine braking. I'm not sure what kind of diesels you have been driving, but they're not typical.

Another Attack, On Law Firm Suing China

EvilRyry I don't think there was anything unusual (131 comments)

"There are attacks every day. I don't think there was anything unusual," Mr Ballmer added.

Seriously, Ballmer? Have you read the part where the Chinese government has been labelled as the attacker of over 30 international companies by Verisign? Not just some guy in China, but the Chinese government. I would consider that pretty damn unusual.

Windows 7 May Finally Get IPv6 Deployed

EvilRyry Misleading Summary (283 comments)

IPv6 is only required for the VPN side. The Internet connection on both sides may still be IPv4 however. Read TFA for more details. I have a feeling Time Warner will be in no rush to upgrade my neighborhood to IPv6 no matter how many companies start using DirectAccess.

Long Live Closed-Source Software!?

EvilRyry EvilRyry writes  |  more than 6 years ago

Jaron Lanier wrote an article for Discover Magazine. His belief seems to be that open source produces nothing interesting, and Adobe Flash and the apparently 100% closed-source iPhone are the coolest things the planet has ever seen. I find it a bit disturbing that a science magazine publishes an article about a software model based on secrets. What happened to the free flow of information that science is supposed to be about? My opinion is that the article only seems to show his lack of knowledge about open source.

Time Warner refuses to fix VoIP problems

EvilRyry EvilRyry writes  |  more than 7 years ago

I've been a ViaTalk customer for about 10-months now. Lately the customer service has gone downhill rather steeply, with 2 hour wait times on the phone, but overall I've been pretty happy with the features and cost.

This past Tuesday around 3:00 PM EST, the VoIP adapter lost its connection to the ViaTalk servers. Despite all the standard tricks, including plugging the box directly into my Road Runner high speed cable Internet line through Time Warner, I was unable to get a connection. Even stranger, free accounts that I've acquired from Ekiga and Wengo also stopped working on all of my home PCs at the same time. I did a tcpdump of the issue from my Linux router/gateway, and was able to easily see the SIP requests outbound, but never received a single reply.

The following day, I took my laptop and VoIP adapter to a friends house (also on Road Runner), plugged the VoIP adapter into the modem and everything came to life. I then connected my laptop to the modem, my Ekiga and Wengo accounts started working too! My friend lives pretty close, but tracepath reveals that the first hop is different. I tried to debug the issue a bit with tools like smap and sipp, all of whose results showed what I expected but no farther clues. The tools worked everywhere but here (friends house, and work).

Conversations with ViaTalk were mostly fruitless. They were able to see the VoIP adapter when it was connected directly to the modem, and verified all the proper settings. Talks with Time Warner were also quite useless. They claimed that they could not help me because I wasn't using Time Warner VoIP service! They also stated that they guaranteed a working Internet connection as part of the service, but refused to recognize that my connection was in-fact not working completely. They said that they could not help me with this problem.

At this point I'd really love to move to a different Internet carrier. Unfortunately, in my area its Time Warner or dial-up. So I ask you, dear Slashdot, what's a man to do?
