codedivine··on Edit scheme on your iPad via the parse tree: Lisping launched
You can distribute interpreters. However restrictions remain:

1. You cannot distribute an interpreter that can be used for running program code downloaded from the internet. So, for example, your user can save their script and use it themselves but they cannot give it to others (except perhaps through the app store bundled as an app itself).

2. Your interpreter cannot dynamically generate binary code so JIT compilers that generate binary code on-the-fly are not allowed.

edit: For example, LuaJIT cannot do JIT compilation on iOS but it can do JIT compilation for higher performance on Android.

codedivine··on No Free Lunch for Intel MIC (or GPU’s)
Your reply contains some weird non-sequiters. Nvidia is right on target when they say there is no "magic" autoparallelizing compiler. The autoparallelization they talk about, and the scheduling issues you talk about, are completely unrelated except that they both contain the word "compiler" :/

As for double-precision performance, it is also well known that the GTX 680 is only for consumers. The HPC version of Kepler is due later this year and I will not be surprised to see it offer much improve double precision performance compared to current Teslas. Intel MIC is not a consumer product, so it is unfair to compare it to consumer products like GTX 680.

codedivine··on Fabric Engine: JavaScript as fast as C++
You should do an introductory article for technical audiences yourself perhaps. Or maybe you already have one?

Anyone have a link to the actual slides from Oracle?
codedivine··on RIM reports Q4 miss; Balsillie resigns as director, CTO out
3: Citrix receiver supposedly works, Splashtop is available 7: Lua is available (check on blackberry github repo) and I have seen experimental builds of Python at least.
codedivine··on Coding Horror - Welcome to the Post PC Era
You are completely ignoring the MS Office market. Try typing an essay or a report on an iPad or making a good presentation. You certainly can, but its not even remotely efficient (or a good "user experience" or "magical").
codedivine··on Show HN: Chat with HN users while you visit HN
Not sure why I am being downvoted here. Is this working on IE9 for other people? Or am I being downvoted for testing something under IE?
codedivine··on Show HN: Chat with HN users while you visit HN
It seems to be problematic on IE9 on Win 7. The chat window is left at the bottom of the page, and if I scroll up, the chat window remains at the bottom of the page. Thus, scrolling and chatting don't go together.
codedivine··on I’m calling it: Ubuntu is finally ready for the world.
I mostly agree with you. I do recommend Linux to the more technical audience but stay away from recommending to non-tech friends and family.

I think part of the problem can be solved if there was some nice hardware that came with Linux preinstalled, with all the driver configuration work already done for you. That will still not solve the printer issue you described, but the "install graphics/sound/wifi driver" issue can be dealt with that way. Sure Linux is not properly compatible with every wifi device out there, but neither is, say, OSX. OSX gets around the problem by the fact that it only ships on Apple hardware. It would be great if we had Canonical computers for example.

edit: FWIW, I do commend companies like System76 and ZaReason that ship linux based systems but we need bigger players in the space to make a difference.

codedivine··on The Linux Setup, Noah Lorang, 37signals
For Linux buying options, I would recommend System76: a variety of systems (desktops, laptops, servers) with Ubuntu preloaded. They are a Linux-only vendor and so are serious about making sure their hardware choices are Linux compatible. Thus, you don't have to worry about compatibility issues or driver hunting etc. https://www.system76.com/
codedivine··on Nokia launches 808 PureView with 41MP camera
Pureview whitepaper: http://press.nokia.com/wp-content/uploads/mediaplugin/doc/no...

Confirms 1/1.2'' sensor size. Approximately 2.5 times larger sensor than the one in the Nokia N8.

codedivine··on Nokia launches 808 PureView with 41MP camera
To people not in the know, the actual physical sensor size (in mm^2) is many many times larger than say the iPhone 4S and at least twice as large as many standalone compact cameras . The biggest sensor before this in any cameraphone has been in the N8 (to my knowledge) and this one has an even bigger sensor.

So its not just the megapixels, it is backed up an actually physically large sensor. Add in the great Xenon flash (which gives out much larger amount of light than say the tiny LED flash on the 4S) and you get a great cameraphone.

codedivine··on Indian ISP Blocks A Bunch Of Websites
The title is not correct. A movie studio, Reliance Entertainment, won a case in the court where the judge ordered ban of a few sites such as Megaupload. Given that it is a court order, ISPs (all of them) had to block it.

In this case, it is the court which is responsible for such sweeping judgement and not a single ISP. I guess the fact that Reliance also owns an ISP resulted in a confused title.

codedivine··on Show HN: We just launched our MVP, a new RSS Reader
Bug report: I am using Opera 11.60 on Linux (64-bit). When I click on "blank" pack, Opera hangs and I have to terminate the application.
codedivine··on Raspberry Pi reveals the final PCB design for the $25 PC
Well, I think the idea is that you will plug it into a TV that you probably already have in the house. Thus both the HDMI port and composite TV-out. Keyboard and mouse still will be required though.
codedivine··on US Bill Creating the Great Firewall of America
I don't get why Pfizer, Adidas etc are supporting this. What do they gain out of this?
codedivine··on Open64 Compiler Version 5.0 released
To those new to Open64, it is a high-quality compiler, with some good internal design and good optimization phases. SGI's former compiler team was highly respected within the compiler community.

It is unfortunate that it is not more well-known. However, it is used by a lot of compiler research groups to prototype new ideas.

codedivine··on Mobile Web Apps Still Have Some Major Hurdles
Not sure about CSS3, but RIM has promised WebGL on Playbook/BBX soon.

(Sure, it is not a popular platform, but just pointing it out.)

codedivine··on What happens to RIMM's QNX OS UI/platform now that mobile Flash is dead?
Flash is still very much alive in the form of AIR

Yes, this cannot be emphasized enough.

codedivine··on What happens to RIMM's QNX OS UI/platform now that mobile Flash is dead?
I don't see the problem here.

1. Adobe is continuing the development of AIR and AIR 3 is coming to QNX.

2. RIM's Torch browser is one of the most standards compliant browsers out there, if not the leader. Even WebGL is coming to the platform.

3. RIM is also going to offer a native UI toolkit called Cascades and the demos look promising. You can also use Qt for native development.

edit: 4. ANd of course, there is also the Android app player supporting Android's UI framework.

codedivine··on Missing Person - Tracy Williams, Technorati Employee
Technorati people, in case you are reading this, it might help to post more than one photo of her. Sometimes, it is hard to remember or recognize faces, when you have only seen one photo.

I hope everything turns out all right.

codedivine··on $149 for a Touchpad if you sign up as a developer
Not necessarily. At least a couple of devs I personally know have made more money on WebOS than Android (none of them developed for iOS so no idea about that).
codedivine··on Nokia announces the Lumia 800, the 'first real Windows Phone'
First off, S40 isn't Symbian. Secondly, didn't you just ask for a featurephone then why do you care about the platform?
codedivine··on Contribute to the Qt Project
Well think of it as follows:

1. Windows phone is currently not suited for mid-range phones, and wont be till the next version. However, long term plan is to definitely push Windows phone towards a wide spectrum of price points and replace Symbian. This will take 2-3 years.

2. For now, till the time WP is ready for mid-range, Symbian is still alive. New devices are still coming out, primarily targeted at mid-range. Nokia aims to sell around another 100 million symbian devices, all of which will run Qt. I would expect Symbian sales to continue for another 7-10 quarters.

3. Even below smartphones, the so-called "feature phones", the space is evolving to accomodate even smarter devices. Nokia sees a big opportunity in making the sub-$100 devices smarter (we are talking unlocked prices here, not american subsidized ones). Those price points will be achieved with Nokia's own software stack. Currently, this includes S40 where you can write applications using J2ME. This will be evolved so that in the future you can write applications for such devices using Qt which is vastly better than J2ME. As an example of this space, Nokia recently released a sub-$100 small touchscreen featurephone with inbuilt offline Nokia Maps. Nokia calls this low-end effort as its connect "the next billion" effort. Likely Qt will debut on these devices next year, when Qt 5 will be ready.

codedivine··on Contribute to the Qt Project
"KDE applauds Qt's move to open governance": http://dot.kde.org/2011/10/21/kde-applauds-qts-move-open-gov...
codedivine··on Contribute to the Qt Project
This is purely FUD. Nokia employees remain the largest contributors to Qt, and as I said above, it remains a key component for their strategy for price-points below those offered by Windows Phone.
codedivine··on The Qt Project is live
You got it the other way round. QT is LGPL, PyQT has always been GPL. For Python, there is an alternative Qt binding called PySide which is LGPL.
codedivine··on Contribute to the Qt Project
Well, the project has simply transitioned to open governance, which means anyone can contribute and move up the value chain based on meritocracy. So, for example, KDE folks can now directly contribute to Qt and also directly affect its future direction.

Trolltech/Nokia employees remain inside Nokia, and continue contributing actively to Qt (they are the largest contributors by far currently, I remember reading 85% of contributors being Nokia). Nokia continues to use Qt for Symbian/Meego as well as their future low-end platform, which currently only offers J2ME. They have officially announced that Qt will be used for "the next billion" which has been referred to as Meltemi software in leaks.

codedivine··on R.I.P., the movie camera: 1888-2011
On the other hand, I am hoping people won't be storing content in proprietary formats without a spec, or heaven-forbid with some DRM restrictions, or you might not have the proper software (or the proper rights if DRMed) to play it back 50 years later.
codedivine··on WebGL Endless Forest
That should theoretically support WebGL. I remember running WebGL on a Radeon 3200. Check from amd.com for new drivers.
