Using EXA with VIA hardware

According to xorg.freedesktop.org, EXA now works with VIA Unichrome:
Supported:
* i128 (Solid and Copy only so far, incompatible with DGA, only tested on T2R4 cards)
* radeon (r100/r200 with Render accel, r300 and r400 core-only. DGA 2d acceleration unsupported).
* sis (sis/xgi; Solid and Copy only)
* trident cyberblade and xp4 (Solid and Copy only)
* via (Solid, Copy, Render)
However, when I add
Option "AccelMethod" "exa"
to the "Device" section in xorg.conf, EXA is not used, and I get this in Xorg.0.log:
(WW) VIA(0): Option "AccelMethod" is not used
This happens with both the xf86-video-via and xf86-video-unichrome drivers. Could someone please explain to me why this is happening, and how I can get EXA working with one or both of those drivers?

What makes you think Xorg 7.1 will be better with compositing in the classic ways? EXA has been improved, but it's still experimental and slow. The only improvements I've seen is rendering glitches that got solved and a complete API change to make it more usable.
You will need an OpenGL compositor, like metacity or a patched up version of compiz, and then, you still won't be able to use compositing with AIGLX, since the required driver extensions are not implemented in all DRI drivers.
Also, rendering on a shitty VIA chipset with shared memory and experimental flaky drivers (what else would you call a chip where 3 driver projects exist for and where the developers don't like eachother) don't know what is faster, CPU or "GPU" rendering...
Wait, the required extensions haven't been implemented at all for Via hardware? I thought that it could do compositing if it could handle textures with OpenGL...
(FWIW GPU rendering is faster than CPU rendering on my machine. Unichrome is very low-powered hardware, but for most things it's good enough to get the job done.)
The only plus of the VIA chips are the documentation which are available unofficially. The only problem with it: it's taiwanese english, which means your VIA unichrome card has grammar correction instead of gamma correction on some pages of the specsheet.
LOL, that probably is a big problem. Might explain the crashes with BZFlag.

Adapter to use 3G with older hardware

I just bought a new car (Aston Martin) and it has an iPhone/iPod plug which is integrated into the car's audio system. Unfortunately, the folks at Aston must still be using old iPods to test with because their new cars don't work with new iPods or iPhones. You get the "accessory not made to work" message when you plug it in.
I know that there is the power adapter from Scosche which will let me at least charge my iPhone, but I also want my car to be able to control my music too, and the Scosche adapter doesn't fix that part of the problem.
So, the question is, is there a different adapter out there that fixes the entire problem and let's older "interfacing" hardware work with the newer iPod/iPhones?
Thanks,
_Brian

Well, interfacing hardware all use the same protocols to talk to the iPod/iPhone. They're not doing anything funky. It's just that Apple changed those interfaces in the new hardware in 2008 so old accessories stopped working. From what I'm told it was because Apple wanted a way to make money from the accessory manufacturers, so those companies now have to pay for a license to use some special chip to make their devices work with the new iPhones.
So... what that means is that I need an adapter that has this chip in it and is able to translate the interface coming from old pre-2008 hardware to the new 2008+ hardware. It should be doable, but I just don't know if such an adapter is out there.

Using ColdFusion with input hardware

Hello,
I am really new in this Coldfusion world and I was wondering
if it's possible to use some hardware to input information into
some modules and if it's easy to get the data.
Thank you
Where can I find an example?

ColdFusion is completely irrelevant to this question, unless
you are
thing of some unusual situation.
ColdFusion is a application server that runs on a network
server. It
will handle data and requests sent to it by a web server. The
web
server responds to request from clients usually using a
browser, but
increasingly by other tools.
It is this end client tool that needs to understand an
alternate input
device such as a bar code scanner.
At the other end, ColdFusion just does not care where the
data comes from.

I have a late 2009 iMac, with a Nvidia 9400 Graphics card. I was wondering what my options are for upgrading. I use Windows 7 via Bootcamp, so I need a card that is compatible.

I have a late 2009 iMac, with the default Nvidia 9400 Graphics card.
I was wondering what my options are for upgrading. I use Windows 7 via Bootcamp, so I need a card that is compatible/has available drivers.
This is for gaming. On the lowest settings of "Call of Duty 4", I get about 100 FPS... Was hoping to be able to play on higher resolution w/o the fps lag.
I'm not good with the hardware part of computers at all, but know how to get around the OS.

In most cases the graphics cards in iMacs are Not upgradeable. They are usually soldered to the logic board. RAM is considered, along with harddrives, the only component that is upgradeable in an iMac, unlike in PC's. So basically you would need to sell your unit and purchase an iMac with a more powerful graphics card.
Hope this helps

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing wireless network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. I am using a set of speakers from kenwood connected to the airport express. The operating system on my macbook is mac os X 10.5.8. i am sure it is not a problem of streaming music online because i have even tried playing music which are stored in my macbook.
Is there any problem with the setting in itunes or quicktime ? Kindly reply...... I am waiting for your valuable suggestion.
Thank you a lot in advance.

I am shocked to have found this same AX audio dropout problem starting TODAY, every few seconds the audio just drops for a couple seconds and then resumes: Latest software versions of everything. No iPad, iPhone or Touch. Internet hardwired to D-Link DES1105 (1000baseT Switch) hardwired to new 80211N AX, AX optical to stereo, AX Wi-Fi internet to basic 1st-gen MacBook operating at 80211G, and an older 'G' AX extender at the far end of the house, away from all this. The MacBook streaming iTunes is usually 12 feet from AX. I've used this setup for years of trouble-free AirTunes / Airplay until today. Today I also found 2 very reliable fixes and 1 way to force a dropout, but first, I read some posts and tried ALL following settings one-at-a-time and restored them ALL because NONE of them helped: Turned off IPV6. Streamed to multiple speakers 'Computer' and 'AX' (restored to just AX). Turned off 'Ask to Join new (WiFi) Networks'. Turned off Bluetooth (can't live without Magic Trackpad, so glad that wasn't it). Here's my discoveries: Lo and behold, each time I click the Airport icon in the Menu (you know it shows you've got 4 bars from AX) when the status switches to 'Looking for Networks' for a second it CAUSES the AX audio to drop out for a couple seconds (it never did that before today.) iTunes still playing, streaming, AX laser still lit, but the 'PCM' light on stereo and the sound GOES OUT EVERY time I click the Airport icon in the menubar, just like the regular, annoying dropouts. So, to reduce traffic I quit Safari (3 tabs, no streaming, just Gmail, Google, and Netflix browsing). Lo and behold, the dropouts stopped altogether. No other Web apps going (not iTunes Store, Genius, Ping, nothing), so I launched Chrome to the same 3 tabs and the dropouts HAVE NOT RETURNED. That's right, not only did simply QUITTING SAFARI cure it, and Chrome doesn't contribute to it, but I can demonstrate it just by forcing my Airport to re-scan. Works for me, written using Chrome. The other reliable fix is to hardwire MacBook to the Switch. This is obviously not ideal, but Airplay audio doesn't drop out over Ethernet. Also, in all my tests, it made no difference whether iTunes did the streaming, or Airfoil did.

Welcome to Apple Support Communities
Of course. If your Mac is compatible with AirPlay Mirroring, you can watch your DVD in your TV with the Apple TV. Read > http://support.apple.com/kb/HT5404 You just have to play the DVD on your MacBook and turn on AirPlay Mirroring.
If your Mac isn't compatible with AirPlay Mirroring, you can use a third-party app like Beamer

How to use authid with rwservlet via WebLogic Thin Client

1. Using J2EE Thin Client for WebLogic (WL) to submit interactive requests for Oracle Reports (App Server 10g) running on another server without SSO.
2. After starting basic Infrastructure, we start rwserver in batch mode (no other mid-tier components are used).
3. It appears that the cgicmd.dat file in the Thin Client conf directory on the WL server controls the DB access with the key:connect string info it has.
4. We had been allowing the testers to come in via the web through a SunOne (iPlanet/Netscape) web server instance, which in turn connects to the WL server running the Thin Client instance.
5. We noticed that anyone could run rwservlet to view report status with the showjobs command via a URL through the same mechanism as point #4 above, and were concerned about security of the reports - "bad".
6. Then someone realized the showmap command could also be specified, and thus see the DB connect string (Id/pw/SID) - "worse".
I researched securing Reports, and read through the white paper, "Securing Oracle9i Reports", and although it discusses security without using SSO, all it says is "users accessing a secured instance of Oracle9iAS Reports Services will be challenged to identify themselves by the Reports Servlet, using its own authentication mechanism (as with Reports6i)", but I can find no explanation of how that works, nor how it would work with the WL Thin Client.
Questions:
1. How are the Id's/passwords set up under AS 10g "as with Reports6i" in this environment going through the WL Thin Client?
2. Is there anything else that needs to be done to secure the created reports, and the connect string info (i.e. using authid with rwservlet?showjob, and not allowing the rwservlet?showmap to be executed at all)?
TIA,
ROC

the JDBC Developer's Guide (11gR2)
gives an example in chapter 9 under "JDBC Thin Driver Support for Encryption and Integrity", sub- "Setting Encryption and Integrity Parameters in Java"
from Oracle SQL Devloper, without redirecting the client to use the OCI/thick driver, choose, new database connection, connection type Advanced. add the entry from the example noted above to the Custom JDBC URL form.
for example:
Properties prop = new Properties();
prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_ENCRYPTION_LEVEL,"REQUIRED");
prop.setProperty(OracleConnection.CONNECTION_PROPERTY_THIN_NET_ENCRYPTION_TYPES,"(AES128)");
OracleDataSource ods = new OracleDataSource(); ods.setProperties(prop); ods.setURL(jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxxx)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=xxxx)(INSTANCE_NAME=xxxx))));
Connection conn = ods.getConnection();
strange side note!, we could not get this to encrypt unless the sqlnet.ora file included the SQLNET.ENCRYPTION_SERVER=required. if this was set to default(accepted), and even though the jdbc thin client properties set to required, the network traffic was still clear text.
good luck

Is it possible to connect an external camera via bluetooth to the Iphone 4 and use it with Facetime, if not.. why?

Ok, in 2015 is it possible now? I would like to use an iPad and Face to share content between a dressmaker in Asia and a customer in the US, and I would like to attach better camera's than the built-in camera's on the devices.
Any thoughts? Any updates to the original post?
Thanks,
