Maxim 17-Sep-2009 [4261] | 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 [4275x2] | 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 :-) |
which is what SWIG basically does directly. once a C library (.lib .so or .dll) is mapped to SWIG you can export it into any output module you want... since MANY libs have already been setup for SWIG, providing an output module for R3 extensions means we'd have access to many libraries right away. no need to do the complicated work, just a one-line command saying basically, give me access to that for rebol . | |
Henrik 17-Sep-2009 [4277] | The essence would be to make this work as painlessly as possible for developers. If it takes to download a single DLL and load it with one line of code to make R3 magically do extra stuff, that's the way it should be. 1. REBOL 3 2. SQLite 3. Profit! |
Graham 17-Sep-2009 [4278] | Sounds like this should be a high priority for the team at Sassenranch ... |
Maxim 17-Sep-2009 [4279x2] | yep. I'm pretty sure SQLite provides the .lib as part of its dev distro.. so we could either: -build the Rebol-SQLite wrapper as an extension using the static lib so it contains both SQLite itself and the wrapper... -Load the DLL dynamically. but then if the DLL doesn't match your extension's expected version, it won't load. welcome to DLL hell ;-) this being said if DLL is registered properly, you can ask for a specific version and it will be returned since Windows can have multiple versions of any DLL installed concurrently. |
with callbacks (devices?), there is no need to keep bugging Carl about A LOT of things people keep complaining about. :-) | |
Pekr 17-Sep-2009 [4281x4] | SQLite ... I am trying my first steps with C language, and I would really like to prefer DLL in DLL wrapper. While it might seem as being complicated, Ashley's driver uses something like 6-10 functions from the whole library? Having wrapped DLL in such a way has a huge advantage - each new version of SQLite does not require you to rebuild your Extension numbers the platforms you are porting to. And SQLite frequent releases are happening quite often ... |
we should move to Extensions group ... | |
ARM announced DualCore 2 GHz A9-Cortex core CPUs, which consume 250mW under full load. Impressive. Apple is rumoured to use those CPUs in their upcoming tablet device: http://www.theinquirer.net/inquirer/news/1533877/dual-core-arm-chips-apple-tablets | |
Finally devices with battery lasting for several days, not several hours, possible? We'll see ... good times ahead :-) | |
Maxim 17-Sep-2009 [4285x2] | the gfx card is responsible for a lot of the watts being consumed... more than any recent cpu in any case. |
we can build fanless high-performance CPUs but high-performance fanless GPU are still not really a reality afaik | |
Pekr 17-Sep-2009 [4287] | Maxim - you are wrong - nVidia's Tegra based device is claimed to offer devices lasting 25 days on battery. We will see :-) |
Maxim 17-Sep-2009 [4288x2] | are they shipping yet? |
and are they "high-performance"? | |
Pekr 17-Sep-2009 [4290] | http://www.youtube.com/watch?v=_p69T3cWHBs |
Maxim 17-Sep-2009 [4291x4] | looks pretty good. :-) |
holy shit!!! http://www.youtube.com/watch?v=_MnHb0UNsEs&NR=1 | |
real time tracking in 3d space, real-time color-keying.... simultaneously! | |
finally someone giving the iphone a bit to think about innovation :-) | |
Sunanda 17-Sep-2009 [4295] | Google puts forward a new language: Noop: http://code.google.com/p/noop/ |
BrianH 17-Sep-2009 [4296x2] | I saw that one - but not all on Google Code is from Google :) |
Forget what I said - apparently this one is. | |
Henrik 22-Sep-2009 [4298] | http://code.google.com/chrome/chromeframe/ This is interesting. |
Graham 22-Sep-2009 [4299] | Yeah .. let us know if it works |
Maxim 22-Sep-2009 [4300] | taking over the web one browser at a time ;-) |
BrianH 23-Sep-2009 [4301x2] | WinCE 6.0 R3 released, with a new UI based on Silverlight with a native code backend instead of .NET: |
http://www.eweek.com/c/a/Windows/Microsoft-Brings-Silverlight-Windows-7-Connectivity-to-Windows-Embedded-CE-275855/ | |
Pekr 23-Sep-2009 [4303] | Interesting - where are they heading with WinCE? Really interesting ... |
BrianH 23-Sep-2009 [4304] | Well, it's the foundation for their phone platform, and so they have to pull out all of the stops due to the competition. |
Pekr 26-Sep-2009 [4305] | Microsoft releases code for "multikernel" research OS - Barrelfish - http://www.osnews.com/story/22241/Microsoft_Releases_Code_for_Multikernel_Research_OS_Barrelfish_ Most of us are probably aware of Singularity, a research operating system out of Microsoft Research which explored a number of new ideas, which is available as open source software. Singularity isn't the only research OS out of Microsoft; they recently released the first snapshot of a new operating system, called Barrelfish. It introduces the concept of the multikernel, which treats a multicore system as a network of independent cores, using ideas from distributed systems. Credit: News taken from OSNews.com |
Pekr 29-Sep-2009 [4306] | Another MS Research OS - Helios ... sounds like a distributed REBOL :-) Helios is an operating system designed to simplify the task of writing, deploying, and tuning applications for heterogeneous platforms. Helios introduces satellite kernels, which export a single, uniform set of OS abstractions across CPUs of disparate architectures and performance characteristics. Access to I/O services such as file systems are made transparent via remote message passing, which extends a standard microkernel message-passing abstraction to a satellite kernel infrastructure. Helios retargets applications to available ISAs by compiling from an intermediate language. http://www.osnews.com/story/22251/Another_Microsoft_Research_Operating_System_Helios |
amacleod 29-Sep-2009 [4307] | Was not something called Helios connected to the Transputer chips theye were working on for use with the Amiga way back when... |
Pekr 29-Sep-2009 [4308] | Don't remember anything Helios and Amiga name related. The chip which was supposed to replace AAA chipset (even AAA was never released, but if it would, it would save Amiga for another 5 years) was called Hombre, and it was done by Dr. Ed Hepler. It allowed to interconnect more chips. Interesting thing is, that if was CPU + GPU in one chip. Simply put - once again Amiga 10 or more years ahead of the competitors, as nowadays it is being regarded very modern to provide unified chipsets like that :-) http://en.wikipedia.org/wiki/Amiga_Hombre_chipset |
Henrik 29-Sep-2009 [4309] | http://jwz.livejournal.com/1096401.html Experience with developing and distributing an app for the Palm Pre. |
amacleod 29-Sep-2009 [4310] | There was another side project using transputer chips (not sure if it was Commador project) that allowed multiple transputers to multi-process. THe first board contained four transputers but theoretically there was no limit to the number of transputers and the gain in process power was linear and did not level off as regular processors do (or did back then). I think Helios had something to do with it... |
