Henrik 4-Sep-2009 [4226] | I'm not so worried about travel distance for most electric vehicles. The cool thing is that it won't take much to replace the batteries with better ones eventually. The motor remains the same. With the development of graphene batteries, it sounds like we can increase battery life to at least twice as much, perhaps 4 times. |
Sunanda 4-Sep-2009 [4227] | I am an urban city bicycle commuter. I'd need a minimum range of 15Km a day. And I'd want 30km for flexibility. Also, I suspect the range is dependent on the weather [FAQ says <the YikeBike works best in mild climates>] so the actual range would be less than the quoted 9-10km for anyone outside of summer conditions. That's one of the issues that sunk the Sinclar C5. Power ..... The FAQ implies it is powered from the electicity mains. Average cost EUR0.10 per recharge. Now, if you could set it up as a static bike and recharge it by pedalling.... |
Geomol 4-Sep-2009 [4228] | So unless the electric power come from a windmill or similar, it's not really green. |
Graham 4-Sep-2009 [4229] | What sunk the C5 was that they were invisible! Too low in the road. |
Geomol 4-Sep-2009 [4230x2] | It's like the danish "Ellert": http://www.ellert.info/ I see them a seldom time on the danish roads. They're not a big success. |
They should concentrate on this: http://www.moller.com/ ;-) | |
Henrik 8-Sep-2009 [4232] | http://seclists.org/fulldisclosure/2009/Sep/0039.html Vista/Win 7 users should probably read this. |
Geomol 8-Sep-2009 [4233] | -> Humour ;-) |
Robert 8-Sep-2009 [4234] | Well Win-7 is not yet there, so use-on-own-risk but Vista is there. That's really a cool one. |
Henrik 14-Sep-2009 [4235x2] | Haiku OS alpha 1 released. So when is R3 going to be ready for it? :-) http://www.haiku-os.org/ |
runs pretty OK. seems similar to BeOS, but not much new. | |
Pekr 15-Sep-2009 [4237] | ClarkConnect (some of us use it) renamed to ClearOS - http://www.clearfoundation.com/ClearOS-Overview/clearos-overview.html |
Pekr 16-Sep-2009 [4238] | Google releases Chrome 3.0 - http://www.osnews.com/story/22170/Google_Releases_Chrome_3 |
amacleod 16-Sep-2009 [4239] | Funny, I have and have been using v3 and did not know...atleast I did not notice any big differences or know when it was updated.. |
Maxim 16-Sep-2009 [4240] | you see, chrome's release channel system is EXACTLY what I explained R3's should be. separate channels releasing versions independently. |
Pekr 16-Sep-2009 [4241] | ah, I thought that Max could support the model :-) But - some users do ask - what's really new? Google adding few tidbits and raising product main version number? |
Maxim 16-Sep-2009 [4242x4] | new "whole" versions are often changes deep inside the kernel and invisible on the surface. they probably added support for things like html 5 and video, etc. |
like FF 3.5 | |
but I'm just speculating. | |
the iphone can now bragg about having bad applications :-) http://www.osnews.com/comments/22161 | |
BrianH 16-Sep-2009 [4246x2] | Google is doing the continuous improvement model, a good one if you can afford to autoupdate without prompting. We can't. |
Maxim, they already do brag about having bad applications, except they call them "apps" for short :) | |
Maxim 16-Sep-2009 [4248x2] | hahaha |
but now you have a professional "sucky application" dev environment to make your job easy at it ;-) | |
BrianH 16-Sep-2009 [4250x2] | MonoTouch isn't bad - C# actually turned out to be better than Objective C for these kind of things. |
That's why so many games for the iPhone are written in C#, on the other professional C# dev environment for iPhone: Unity3D. | |
Maxim 16-Sep-2009 [4252] | (.net is bad) I wonder how they prted .net to the iPhone. |
BrianH 16-Sep-2009 [4253x2] | Simple: They didn't. MonoTouch uses iPhone wrapper APIs instead of the CLR. |
And .NET isn't that bad, depenjding on what you compare it to. Bad compared to REBOL - good compared to Java, Flash, ... | |
Maxim 16-Sep-2009 [4255x3] | aaaahhh a link just made itself in my head.... novell + mono <> MS 7 new collaborative mindset... yes... mono IS .net as an open source and actually sanctified by MS as a gift . |
so yes, we can actually run .net code on any platform... hell we could even import the .net framework and use it in R3 eventually. | |
(using mono). | |
BrianH 16-Sep-2009 [4258] | And with extensions, we could even call .NET APIs on Windows, such as most of the new Vista/7 APIs. |
Pekr 17-Sep-2009 [4259] | BrainH: is recent Extension API enough to link to .NET, or would you welcome some other additions, as utypes, for such an interface? |
Maxim 17-Sep-2009 [4260x2] | a lot can already be done right now... probably the most complicated aspect is using some of the structs which many of the windows api funcs use. |
and many functions use callbacks too. some just to implement "I'm done" type async stuff. | |
Graham 17-Sep-2009 [4262] | so this means we can be as accomplished as vb.net ? |
Maxim 17-Sep-2009 [4263] | as long as we can map the entire .net spec (probably through mono), in theory yes. |
Pekr 17-Sep-2009 [4264] | Graham - no, not complicated. It is about what reboltutorial suggests - how can REBOL be successful, if it can't integrate to business systems? Scala is becoming popular. I would like to use REBOL at my work. So - how do I query Active Directory, to get me listing of users? Bzzz ... you can't easily do such stuff with REBOL. REBOL is cool, but a bit in an isolation. |
Graham 17-Sep-2009 [4265] | Me too .. I'd like to use a lot of stuff that I simply can't |
Maxim 17-Sep-2009 [4266] | again, SWIG might be the solution here... this whole topic needs a lot of research. |
Pekr 17-Sep-2009 [4267] | IIRC e.g. Robert is using comlib to access MS Excel API. Without it, he could not use REBOL at all for the task given. He does NOT code in .NET, he uses its API to get access to systems, apps, and their data ... |
Graham 17-Sep-2009 [4268] | swig?? |
Maxim 17-Sep-2009 [4269] | a tool which scans entire repositories of C/C++ code and builds bindings for various interpreted language... its one of the reasons python gets everything first... its totally integrated into SWIG... for example, SWIG was used to build the python OpenGL binding. its just a question of getting the .h or the sources. and then saying... I want to use it in [select language]. |
Pekr 17-Sep-2009 [4270x2] | how big SWIG is? How do you work using it? |
http://www.swig.org/ | |
Maxim 17-Sep-2009 [4272x2] | so building an R3 extension output module for it means OTHERS, non rebolers could provide the tools for us for free as part of their distros. |
its not a simple system AFAICT, but a lot of people are using it, and its code parser is VERY complete and is used for VERY LARGE projects. | |
Henrik 17-Sep-2009 [4274] | I guess you would build extensions per DLL. one for openGL, one for SQLite, one for audio, etc. no crisscrossing? |
Maxim 17-Sep-2009 [4275] | exactly... in fact, OpenGL provides the .lib files directly, so you in fact compile your own OpenGL DLL directly... no need to double reference the DLL :-) |
