Thunderbolt interface is PCI-E interface to the outside. There are already external graphics "cards" (can't call them a card really) which use various connectors (ATI had a good idea but buried it), mostly USB but these kinds are just to connect another monitor. If Thunderbolt has wider adoption there are going to be fully featured graphics "cards" for notebooks which would allow gaming.
You can use polarized light filter for photo lens. It can be rotated to get rid of the right angle of polarization. Of course holding it before your eyes makes it obvious as well.
By the way circular polarization (CPL) photo filters are still linear polarization filters (because they are meant to be rotated) but they convert linear polarization into circular because it is better for digital sensors. So if circular polarization is used on this monitor, this isn't going to help.
Actually Intel's VA API has backends that use VDPAU and something from FRGLX. I am not sure these backends are tested well but in theory an application that uses VA API can use acceleration provided by all three major graphics hardware vendors. In addition to decoding VA API can be used to accelerate encoding and post-processing filters.
Linksys is a joke, especially since a word Cisco is written on it. I bought WRT150N and it didn't work over an hour under torrents load with its default firmware. The router hanged and had to be hard reset. And that with just 6 Mbit/s ADSL. Right on Linksys support forum I read about alternative firmware from some guy who had the same problem. I flashed dd-wrt on it and never had hang ups again. But maximum bandwidth in LAN I can get is about 25 Mbit/s. After such experience would never suggest buying Linksys to anyone.
Basically, I would NEVER allow remote web management of a device if it's on the internet. I believe the default for DD-WRT is to disable it as well, so you'd have to go in and tell the device that you want to enable this feature. All in all, I think for most users, this issue is a non-issue.
Sure in DD-WRT external web access is disabled by default so it is necessary to enable it manually. But it is a quite convenient thing because DD-WRT provides a Wake-On-Lan functionality and it is possible to turn computers on in the LAN. When I go to work I can leave my home computer off and if I need it, I can turn it on using my router. Now I had to disable external web access until I update firmware to a safe version.
We've been through CVS, SVN and finally GIT when developing our code internally for a big open source project before opening it.
Git actually requires changing the mindset for developers from producing the code to producing the patches.
This is an excellent description from one of my colleagues and I think that Git is ideally made for making patches. Patches are what are valued and needed in the open source world while it is still often different for the corporate inner projects.
When we were going to open source the code and understood that we'll have to behave like it is done in the open source, send patches to committers, Git became a natural choice although the central repository of the project is in SVN (Apache repository). Developing patches is different from developing the code in a small sized team. Git offers absolutely the greatest power to operate with code changes (patches) locally than any revision control that I've seen.
The article misses a tremendously useful feature of Git called "rebase". It is useful when you develop some changes against a trunk that changes while you work on your code locally. You make some local commits and to make them synchronized with the current state of trunk it is necessary to rebase them on the new version. Git does it by far in the most convenient way I've seen applying all of your local commits one by one and asking to resolve conflicts when it is necessary. Of course it requires some discipline to commit locally in small portions, but it is easier than "merging often" with the trunk of development than subversion handbook says. Merging is often tedious and it is way easier to just commit small changes to a local repository than every time resolve the same conflicts when "merging often". You never have to resolve a conflict again after you've done rebase with Git.
I didn't find performace on windows so bad. Cygwin port works ok, not so fast as on Linux, but it is good enough compared to subversion update. TortoiseSVN has to keep a separate cache to make windows performance decent. This cache is sometimes renewed and slows down a system for a long time if your checked out repository is big enough. All of subversion transactions like "svn log" require server interaction while Git is lightning fast. So I think even if filesytem performance of Git to clone or checkout may not be so good on Linux it is compensated with no delay to do every day commands like log, annotate, diff, etc.
Yes, maybe overclocked this far it will attempt to compete on linux with nvidia which have decent drivers. But who cares about extreme overclocking when drivers are shitty.
Well, some languages now influence those that were traditionally conservative and used to develop things like kernel. There is nothing wrong with exceptions except that their implementation in C++ is a heavy bloat on the code and quite a slowdown on its performance (I saw -fno-exceptions option in most c++ packages that I installed, and it was used for a reason). Languages like java which use exceptions heavily are not a panacea, they rely on the same mechanisms only the code is generated by JIT (well C++ requires executing destructors which java doesn't require so maybe java exception handling it lighter only to be overwheited by garbage collection in a different department:) ) But computing industry evolves. If there is a strong demand for something there is eventually going to be a supply. Hardware vendords aren't blind when they compete against each other and exception handling may evolve into several new processor instructions that will speed up everything first on one platform, then on the rest of them. It is a matter of competition.

You don't have to use text mode browser. In most cases gentoo livecd boots into framebuffer, so you can use "fb" driver for "links" (by far more advanced browser than lynx in my opinion). Use "links --driver fb www.gentoo.org" on some virtual console to browse the site and forums. You can't usually install gentoo without internet connection and if you do, you usually already know what you are doing.
Look at the file crypto/bn/asm/sparcv8plus.S. It contains mulx and stlx instructions which are the 64-bit SPARC instructions. This is possible because even UltraSPARC sparcv8plus target is target for building 32-bit pointer application but allows 64-bit math. When OpenSSL configure script sees that you compile on any UltraSPARC, it enables assembler code that uses 64-bit math regardless of which memory model you've specified.
This is why 32 and 64 bit applications performed on the almost the same speed but 64 bit application was slower. They both used 64 bit math instructions, but 64-bit application also used 64 bit pointes.
From man of Sun CC compiler:
v8plus Compile for the V8plus version of the SPARC- V9 ISA.
By definition, V8plus means the V9 ISA, but limited to the 32-bit
subset defined by the V8plus ISA specification, without the Visual
Instruction Set (VIS), and without other implementation- specific ISA
extensions. This option enables the compiler to generate code for good
performance on the V8plus ISA. The resulting object code is in
SPARC-V8+ ELF32 format and only executes in a Solaris UltraSPARC
environment -- it does not run on a V7 or V8 processor.
Example: Any system based on the UltraSPARC chip architecture
As much as I like Gentoo it's not quite true, applications have to be portable too. For example you cannot access memory on address unaligned on its size on SPARCs (I fixed a mistake like this in an early version of mplayer). I am not sure about Itanium (it is likely it has the same limitation as SPARC), but ia64 and amd64 are still considered experimental in gentoo. And there are always issues with exotic hardware that exists on some architectures.
I don't agree when someone who fights for freedom lies to the whole world about their motivation. That's my main protest to this war. The biggest reason that Bush and his command used to start this war that there were weapons of mass destruction in Iraq that threatened US. UN inspections didn't find anything but they started the war anyway.
Now they claim that Saddam's regime was evil anyway (here I agree with them), so the war was justified. But think of it, in future they can say that any country that they chose has weapons of mass destruction whatever anyone else thinks and use this as justification for invading this country. Nice war for freedom, don't you think?
The thing is I didn't have threading enabled in all of my folders. That's the way I prefer to see my mails, no threading, just the order of how they arrive to me (some people that send me emails don't give a shit about the date on their computer, so I can easily get emails sent in 2010 year, so sorting by date doesn't work).
I never said that evolution has to go away, I just pointed out that a younger mail client KMail already supports some things that evolution fails to do correctly.
Why I tried to find an alternative to KMail? I found that it's the only KDE application that I use, so I thought I'd find a GTK/Gnome replacement... so far I didn't. Guess I'll have to look into mutt.
I had to move from evolution as well. Here is the list (copy/paste from gentoo forum) of the most annoying things that I didn't like in evolution 1.4.1... Maybe in version 1.5 they fixed them but I'll probably stay away from it for a while anyway.
Regexp filters don't support ^ symbol. WTF?
Copying several selected mails from folder to folder places them in a random order in the destination folder. This is just a killer. When I imported emails from KMail just copying mails from KMail folders screwed all mail order.
When source email doesn't have charset I can set it by selecting encoding from View menu. But when I reply to this mail quoted text is in iso-8859-1 regardless of what encoding was selected in View. And the resulting charset is of course UTF-8 which not yet understood by all mail clients and quoted text is unreadable anyway in clients that understand UTF-8.
I got several of my mails split into two halves. WTF, every other mail client I used implements correct reading of mail spool file.
I remember I had other problems, just forgot exactly what.
Hmm, so what if I want to use your program on sparc solaris? Or maybe x86 solaris? Or BSD of some kind? Or sparc/ppc/whatever linux?
How exacly does it make it possible to use native widgets on every platform where java works? Does it provide everything in a huge bundle that has to be installed along with your java program?
Actually this is a very similar to what other "embrace and extend" practicing corporations do. Create an extention (yes, I agree that those corporations sometimes even violate a standard, but often there is no standard, just a commonly used set of options) to something which becomes widely used then. This extention is not supported by anyone else other than the new product. Use of this extention is required by users who make use of it.
GNU creates archives that cannot be always unpacked by Solaris tar. GNU rm will not work in interactive mode even if -i switch is present on the command line but then there is -f switch. Solaris rm will act in interactive mode in both cases. GNU utilites support -- long options. GNU make has far wider capabilities that Solaris make.
Those are just the examples out of my head that I could add in 5 minutes of writing this post. There are differences between GNU unix commands and commetrial unix commands that make incompatibilities.
Of course there is a difference with, say, Microsoft practics. You cannot install MS products on a commertial unix while you can install GNU tar, GNU fileutils, GNU make on Solaris and use them just fine.
Of course they want to be on the low end and desktop market. The thing is they've lost this battle with Wintel already, there is no way someone would use a SPARC Solaris workstation over Wintel box except for some proprietary software perhaps.
The price is high because of usual business rules. You don't produce enough of products (SPARC chips, SPARC chipsets), they get expencive (Sun doesn't even own hardware fabrics, their chips are manufactured on Texas Instruments fabrics). You produce a lot of chips (Pentiums, Pentium chipsets), they get cheapter just because of mass production.
On the other hand Solaris is very stable on its native hardware. True that Sun is slow on releasing security patches but other than security the system only fails becsuse of hardware (disk, memory) problems, never because of software (I don't want to give uptimes, but servers run for years). That's why Sun still has customers, customers that have _stability_ as their biggest priority.
Nevermind, I searched gentoo forums and found that I need to use cdrecord 2.x specifying dev=ATAPI:b,t,l . So I'm going to try it when I get my hands on 2.6 computer with CD burner.
Do I need special version of cdrecord to use this? For me cdrecord doesn't seem to have any IDE support so far. Even -scanbus doesn't recognize my IDE CD-RW drive until I boot with ide-scsi option.
So is there any experimental cdrecord version with support for IDE already?

I mean really? What do these traders produce? Nothing. But they earn money, quite big money solely on speculation. What is the purpose of this at all?
