YAXUP (Yet Another Xorg7 Upgrade Post)

I've finally solved all my former problems with Arch (wireless, printer), so I needed a new challenge. I decided to answer Y instead of n to the pacman quiz question: replace xorg with xorg-server? I assumed I had some sweaty hours ahead of me, but I've gone through the same procedure on my work computer (which I only use to try out things like this before I do them on the laptop).
I was right: there were some problems alright, but nothing that I couldn't eventually fix, more or less, thanks to info in this forum.
Below are some problems that remain, either as problems or as puzzling things which may or may not turn out to be more problematic. I currently have a running machine. Can't say I notice much of a difference so far, but then again, I've mostly been editing xorg.conf in a non-x-shell so far :-)
sound:
Error message on startup:
device /dev/dsp can't be opened (No such file or directory)
The sound server will continue, using the null output device.
The pcspeakers, which have never bothered me, suddenly act up. I have added pcspkr to the blacklist, so that should be ok, but I assume that this might be related to the sound problem.
In /dev there is no dsp anywhere, and if I run the alsa daemon, it says that no sound cards are found. (I have an intel 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 card, which alsaconf found, but it still doesn't work)
I managed to get it up again with modprobe snd-intel8x0, but it should have been loaded by hwdetect, shouldn't it...? At least, hwdetect --show-modules finds it, so why didn't it load?
Wireless:
my wireless connection has been on eth1 until now, but after the upgrade, it was considered to be on eth0 instead. I've changed all the eth0 to eth1 and vice versa in rc.conf, /etc/conf.d/wireless, and /etc/network-profiles/<wireless profile>, and now it's working again, but I hope I won't have to go through that every time...?
Fonts:
Firefox has problems with fonts. The default font at this site is Verdana, which I have installed, but Firefox displays it as Times (I believe it is).
I changed the default font setting in about:config from Bitstream Sans Vera to some other font, and true enough, that other font was used. So perhaps the problem stems from the Bitstream package, which, I believe, was updated at the same time as I updated xorg? But why should FF look for Bistream at all, when Verdana is called for...? Oh well, this may perfectly well be a FF problem and not xorg-related.
I will look more into the font business, and it seems that most other apps behave themselves.
Mesa:
I've seen it mentioned several times here that mesa is deprecated. Still, if I try to remove it, I get the following error message:
error: this will break the following dependencies:
mesa: is required by jasper
mesa: is required by xorg-clients
mesa: is required by openexr
mesa: is required by qt
mesa: is required by xscreensaver
so I left it in place. Annoying: it seems to slow down opengl (glxgears: c. 500 fps, as opposed to > 1000 before the 'upgrade'), and it conflicts with celestia, which I had to remove. I miss my stars... I want to fly over the surface of Saturn, browse the perimeters of Alpha Centauri,...
[** hits himself hard on the head to get out of poetical mode]
but what do I do?
Desktop:
I have set the kde desktop to display icons for all partitions, mounted and unmounted, but none of that is anywhere to be seen. I can access the data alright, so it's not much of a problem (and I mostly use fluxbox anyway), but I wonder where they went...
Might this have to do with adesklets, which I have installed at more or less the same time as xorg7?

2MrGreen:
I don't have anything like that in the xorg.conf. Here's my file, in case you still need something to look at.

Yet another Gmail IMAP post

I am still fairly new to the mac so bear with me. I try to set up my Gmail account in mail as a IMAP account, (currently it is set as a POP account, and works just fine) when I try to use notes and have it show up on the server, notes goes nuts and keeps repeatedly sending me the same note over and over. I finally have to disconnect it from the internet delete the account, and reconnect to the internet. What is this problem? I have searched for an answer, but none were any help.
Thanks for any help

Hi Devon Dave. I thought as muchbut the weird thing is from the moment I transfered to Bt I have had almost 18 months of trouble free BB and phone then suddenly..... BB dropouts for no apparent reason and the horrible crackly phone line. I shall post again tomorrow after the engineer has been. Its definetly the incoming line as I am currently plugged into the master socket and if I remove all my filters, unplug BB the noise is still there. Its lucky I have such a good deal on my iphone so I can use that for short calls but my lovely wife is getting a tad **bleep** off to say the least.
Watch this space for a new post tomorrow.

Yet another speed issue posting

Dear BT Bods,
I don't know why having subscribed BT Infinity on the promise of better speed and stability that I now find niether to be the case, and beginning to regret ever buying it.
So to cut the chase, and save your time and mine, I am a senior architect working for the core network of a very large UK and global operator, so spare me the script and the brush overs.
I live in Greenford, postal code area UB6 8xx.
The service is painfully slow, and utter rubbish when it comes to streaming anything, and that's nothing to say of the 75Mb/25Mb speed check I did prior to ordering the line.
To cut a very long story short: I have just paid my first bill, and unless the is sorted immediately, then I am going to formally write to you to disconnect the service, and I don't care what the Ts&Cs say - we can always tango in court if it comes to that. I will not be bullied into a 1-year (dis)service.

Probably worth running the speedtest at http://speedtest.btwholesale.com/ and after the test choose ‘Further Diagnostics’ and post the speeds and the profiles that this gives. The mods will want to see this anyway when they get time to process your issue.
I assume you are running over ethernet, not wireless? You could try ruling out HomeHub issues by making a direct PPPoE connection from your computer to the modem (user: [email protected], password: bt will work).
Check the telephone ciruit has not been star wired: with extensions coming off junction boxes between the incoming telephone line feed and the master socket. That's a fairly common mistake than can lead to instability.
Don't forget that the service guarantees for domestic broadband are very different from those expected for the core network of a very large UK and global operator. However, for most people Infinity does provide a fast and very stable connection.

Yet another muse support post: Exit Code 7, ERROR: DW050:

I am so tired of this. I think I've used muse, problem free, once in the past 2 weeks. Here is the latest problem after an attempt to reinstall in effoert to fix an earlier problem.
I click install, it extracts the files, then installs them but bails anywhere from 35%-99%. Then i click "more details" and it opens the browser to display:
                    ++++++++++
Exit Code: 7 Please see specific errors and warnings below for troubleshooting. For example, ERROR: DW050 ...
-------------------------------------- Summary --------------------------------------

ERROR: DW050: The following payload errors were found during install:
ERROR: DW050: - Adobe Muse: Install failed
                    ++++++++++
I'm a creative cloud member and have had no issues with any of the other programs of camparable significance; a few bugs here and there, but this muse product seems to have been a good idea but a little undercooked as far as my experience goes.
Unacceptable for muse memebers to be locked out of the programs they're paying for, but much more important, depend on. I've been a memeber for 2 weeks and it's been nothing but headache with muse. Muse is the product which sold me on becomming a member, now it's the only thing keeping me from publishing the work I've done on all the other programs.

Hi,
I apologize that you've ran into so many issues! Are you installing via the Adobe Applicatoin Manager? If so, try making sure Muse is completely uninstalled first -- if you're on Mac you can drag Muse to the trash and empty the trash, if you're on Windows there may be two entries for Muse under Uninstall Programs. You can search "Muse" in the upper right to filter. Make sure they are both uninstalled. You can then try via the Adobe Application Manager again.
If this still fails to work, please try installing with the following direct download links of Muse (click whichever OS you are using):
Latest Muse Mac: http://www.adobe.com/go/muse_latest_mac
Latest Muse Win: http://www.adobe.com/go/muse_latest_win
Please let me know if this helps.
Thanks,

YASPP: Yet Another Stacksize Problem Post

Hi,
I've just installed the latest community version of Opensolaris, along with the beta of sun studio 12 on a 16-way 32GB amd64 machine. So far this machine has been running with linux+intel 9.1 compilers.
When I tried to run our openmp code, after solving a (very few) porting issues, I found out that it runs fine for the "minimal size" problems. For the minimal size code to run i have to set the stack size to at least ~45056kb (44MB).
However the medium size problem needs exactly 8 times more memory. If I try to set the stack size to 360448kb, I get an "unlimited" stack size, and the program crashes. I guess that by unlimited, the system means I have hit the maximum limit for the stack size. Is there any way to increase it?

It's a bug in the compiler. Let's look at your example program from the OpenSolaris forum:
program stack
implicit none
integer*8, parameter :: k=1024
integer*8, parameter :: s=512*k*k/4
integer,automatic :: foo(s)
integer*8 i
print*, 'allocating:', s/1024*4,'kbytes'
!$omp parallel do private(i)
do i=1,s
foo(i)=1
end do
!$omp end parallel do
pause
print*, foo(1),foo(s)
print*, 'worked'
end program
If I change s to 512k, then look at the assembly code, this is what I see:
$ f90 -O3 -m64 -xarch=sse3 ompstack.f90 -S
$ grep 'subq.*%rsp' ompstack.s
subq $32,%rsp
subq $524392,%rsp ;/ line : 1
That second "subq" instruction is reserving space on the stack for the array. Now if I restore s to 512M, I see this:
devtools-x4200-0$ f90 -O3 -m64 -xarch=sse3 ompstack.f90 -S
devtools-x4200-0$ grep 'subq.*%rsp' ompstack.s
subq $32,%rsp
subq $104,%rsp ;/ line : 1
Looks as though the code that computes the amount of space to reserve on the stack is overflowing. I have filed bug 6541518.
The program will work if you remove the "automatic" keyword from the variable declaration. Most likely, your OpenMP program will also work if you remove "automatic" keywords. Alternatively, you could change the automatic variables to local allocatable variables. Of course, you would then have to insert an allocate statement at the beginning of the procedure.

Yet another "fail to respond".....

I've had a look around on the posts and can't find a problem that quite matches this. I bought my parents a G5 iMac with an external iSight just over a year ago. We've been using iChat happily since then, til today.
Originally I had G4 iMac with iSight on panther. Since then we've both upgraded to Tiger, and I've upgraded to a G5 iMac 2.1 with built in iSight. Still no problems. Just after christmas I invested in a Zoom ethernet modem and tonight was the first time since then we've tried to iChat. Depending on who's trying to accept the chat, they recieve the message that they have failed to respond.
Both firewalls are off and encryption is not enabled. This would suggest to me that it might be my new modem. So I powered up my old G4 connected with my old modem, but still no audio or videochats, with the same error messages.
I don't see why I should be getting the same problem with my old set up too when it worked fine before (G4 running Tiger too).
Any thoughts?

HI Veeto,
Ok your parents may have set up Port Forwarding like this (I can not UPnP listed on this screen shots).
UPnP stands for Universal Pug n Play.
It is one means of making sure the Ports in a cable or ADSL modem are open.
Port Forwarding is another and Port Tiggering is yet another.
Sometimes a cabele modem can be set as a Straight through device much like a USB modem.
An ADSL modem is likely to come with some ports pen by default which allow you to Plug and Play with your Web broswer and Mail applications and Send and get files over FTP.
However iChat uses ports ports above the 1024 threshold for these open ports. This means you have to open the ports.
If you have the Access IP and Default Password and User ID for your 5660ADSL modem then you will be able to do the same.
The page I linked you to has all the ports you need for AIM and Jabber accounts to work.
This is on of the other Zoom's Pages for the same thing. Similar but different.
You should be able to work out how to set yours up.
Ideally you need to use UPnP or Port Triggering to use two computers at one location with iChat as these both allow multiple computer to use the same ports (Port Forwarding does not).
It might be you have newer firmware on your modem than is shown in these pics and you might have UPnP.
http://www.zoom.com/techsupport/adsl/adsl_x3.shtml (Firmware page).
I do not see that it says it has UPnP on thier site.

Another failed upgrade form 40/10 to 80/20 - lost ...

I signed up for BT Infinity Option 2 (unlimited) back in October 2011, and the service was installed, worked consistently well at around 28Mbs down / 5 Mbs up. So far so good.
The BT website offered the option of upgrading from the 40/10 service to the 80/20 service for no charge providing that you agreed to extend your contract term to a new 18 months, so, on the 6th May, I did just that. During the ordering process, the system suggested that around 51Mbs would be a realistic download speed for my line on the new 80/20 service.
On the 9th May my order was marked as complete, the home hub and modem restarted themselves during the night, and come the morning... nothing. Same old 28Mbs speed.
The line needs to train up they say, so wait 10 days. Day 1 - 28Mps, Day 2 - 28.Mps....Day 10 28Mps. Same consistent 28Mps day in day out.
Surely if the line is training, I should expect to see some variation? Apparently not - it's 12 days for the training to complete, so wait longer. It makes no sense to me that I would see absolutely no variation in speed if the line was really training.
I've been bounced around department to department, they've run multiple (un-necessary in my view) line tests, I'd swear they don't really listen anyway to what the problem is, but just go on a robotic 'speed issue blah blah' bender every time you call.
I can't see a way out of this - no one will take end to end responsibility for my case. I can't bear to call them again and jump through the same hoops of resetting, testing and explaining the situation for an hour or two just to end up with the same 'sorry - can't help you'.

Well, I spend an hour or so on the 'chat' with the help team last weekend, testing, rebooting, replugging and was left with yet another - give it 24 more hours. He promised to go away and check with the Billing Team, Order Management Desk and Customer Options team to see if there was anything blocking the migration and call me back the next day.
Guess what? A full week later - no phone call, no difference.
This is woeful customer service - I feel like a victim of fraud - being duped into an extension to the contract when BT has neither the means or the desire to deliver the service. I understand things don't always go smoothly, but for the love of god, it should not be *this* difficult to have something done about it.
Transcript of the last conversation posted in the hope someone else will find it useful...
Vinay Kulkarni: Hello. I'm Vinay Kulkarni. Thanks for that information, I'll check it and get back to you in a moment.
Vinay Kulkarni: Hello David.
David Thompson: Hi
David Thompson: The BT website offered the option of upgrading from the 40/10 service to the 80/20 service for no charge providing that you agreed to extend your contract term to a new 18 months, so, on the 6th May, I did just that (Order No. BTCDxxxxxx8). During the ordering process, the system suggested that around 51Mbs would be a realistic download speed for my line on the new 80/20 service. It also informed me that the new service would be activated within 3 working days, and there would be a short interruption to my service overnight.
David Thompson: I have repeatedly run speedtest.net sessions on the line, and, while I understand that during the initial 10 day 'training' period, line speed will fluctuate, at no point what so ever, has the line speed every increased above the 28Mbs download, which also suggests to me that I have not been migrated onto the new platform, or an artificial cap is somehow being applied. It is now 10 days since the migration was completed, so the training period will now be complete, and still - not a single result above 28Mps.
Vinay Kulkarni: Good Morning. I am afraid that I have not been trained on BT Infinity concerns. However, there is a specialized team who will be able to assist you in regard to the above query. Would you like to speak to them?
David Thompson: Yes
Vinay Kulkarni: I will transfer your chat now.
Vinay Kulkarni has disconnected.
Atanu : Hello. I'm Atanu . Thanks for that information, I'll check it and get back to you in a moment.
David Thompson: Hi - can you see the 'old' conversation above before I was transferred, or do I need to copy and paste it for you?
Atanu : Hi David, I am just reading it. Please give me a minute.
David Thompson: okay - no problem.
David Thompson: I should add that the 28Mps download I refer to has been the steady speed that I achieved ever since BT infinity (40/10) service was first installed in 2011.
Atanu : Ok David, I really apologise for the inconvenience. Please don't worry, I will take care of the issue and solve it for you.
Atanu : I'm just waiting for your account details to load. Won't be long.
Atanu : Thank you for your patience David. I will check the line and resolve it for you.
David Thompson: ok - I just really want to know if the account has been upgraded - I don't think the line is 'faulty' as I get the 28Mbs consistently - I just think it's capped.
Atanu : Yes, the account has been upgraded on 09/05/2012 and it is not capped at all. Please tell me are you at your home as I need to perform some tests in the line to identify the fault and solve the issue.
David Thompson: I am at home - are you saying it has been upgraded to the 80/20 service from the 40/10 service?
Atanu : Yes. Now I will check out where is the fault.
David Thompson: okay
Atanu : Normally it is the first 10 to 12 days when the connection sets in a stabilisation period.
David Thompson: I understand that, but the speed before the upgrade was a consistent 28mbs; the speed after the upgrade (and during the stabilisation period) was a consistent 28Mps - to me, it looks like nothing has changed.
Atanu : Yes, that is the issue I want to check properly.
David Thompson: okay but please don't tell me to wait *another* 10-12 days to see if it makes a difference -
which is the ONLY reply I have had to date.
Atanu : No, you do not have to wait for more than 2 days.
David Thompson: I really do not think this is a stabilisation issue - if it where I would have seen performance both better and worse than the original 28Mps.
David Thompson: I remain convinced that there is no fault on my line, rather I simply have either not been migrated at all, or migrated back on to my original service by accident, or only partially migrated and some settings remain set that are limiting my speed to that of the 40/10 service.
Atanu : Do you any VPN in the Bt connection?
David Thompson: Does your system make a distinction between the two Infinity services - ie. the 40/10 service and the new 80/20 service? I note the order (BTCDxxxxxx8) makes reference to the 40/10 service - which is the one I was already on.
David Thompson: No VPN
Atanu : Ok. Please restart the BT Home Hub by press the power button
Atanu : Wait for 5 seconds and restart it.
David Thompson: I will lose this conversation won't I?
Atanu : No, you will not. I am assuring it. Don't wait for more than 10 seconds.
David Thompson: okay - just the home hub, not the white 'modem' box too?
Atanu : Both.
David Thompson: okay - doing it now.
Communication with the RightNow Chat service has been lost. Please wait while attempts are made to restore the connection.
Disconnection in 240 seconds. Connection resumed.
Atanu : If the chat disconnects. David Thompson: done
Atanu : Thank you. Wait till the lights be steady.
David Thompson: t
David Thompson: it's all back and lights are steady (well apart from the Lan1 one, but that's to be expected)
Atanu : Ok. Please check if the speed is better now?
David Thompson: speed is still the exact same 28Mbs
Atanu : It is a wired connection you are using. Right?
David Thompson: wired or wireless, it makes no difference - both report the same.
Atanu : But is it a wired connection now?
David Thompson: I'll test again with the laptop - give me 1 min
Atanu : Thank you.
David Thompson: 27.71Mbs with a laptop plugged directly into the homehub
Atanu : Please tell me the operating system in the computer?
David Thompson: That one is Windows 7
Atanu : Thank you. The system is saying the speed is being devided.
David Thompson: Divided?
Atanu : May I close the wireless connection for some time?
David Thompson: What do you mean by divided?
Atanu : The connection is been shared by more than one computer .
David Thompson: Well of course it is! Which is why I normally do all my test very early in the morning when I am the only user (I have three kids!). My early morning tests are where I'm basing my 28Mbs from
David Thompson: Do you want me to disconnect all wired and wireless users and re-test?
Atanu : Yes. Please keep just 1 computer connected and check the speed through BT Speed tester.
David Thompson: okay - this chat will temporarily disconnect again then.
Atanu : Can we keep this computer connected?
Communication with the RightNow Chat service has been lost. Please wait while attempts are made to restore the connection.
Disconnection in 240 seconds.
Connection resumed.
David Thompson: Hmm - that did not work.
David Thompson: When I disabled wireless on the hub (from the wired connection) the hub just froze and I needed to power down to get it back to life
David Thompson: I'l get a longer cable!
Atanu : Ok. Please take your time.
David Thompson: Are you able to disable wireless from your end - each time I do it here the hub hangs. I've taken off all other Wired connections?
David Thompson: And it will be via the laptop, so which connection will die when you kill wireless
David Thompson: so you will need to turn it on again within the 240 seconds
David Thompson: That said, the wireless connections are not doing much at all at the moment - they certainly won't be consuming any significant bandwidth
Atanu : Ok.
David Thompson: Do you want me to run speed test now or wait until you kill the wireless - it's all iPad and iPod
doing nothing on the wireless - this PC and the other one sitting idle next to me, so no real activity? Atanu : Not an issue. Please run the speedtester now.
David Thompson: 29.3Mbs down / 4.51 Mps up from the wired laptop connected to the Hub
Atanu : Thank you.
Atanu : David, I will run some line tests now. Please make it sure that nobody is using the landline for next 7 minutes.
David Thompson: okay
Atanu : Hello David, have you faced any connection dropping issue apart from the slow speed?
David Thompson: No - the line has been perfect - no latency issue, solid connections. The only issue is I have not seen any increase in speed above the 38Mbs. I honestly don't think it's a faulty line.
David Thompson: Which is why I think the migration has failed in some way - I'm sure somewhere in the system there is a flag saying that I'm still in the 40/10 service and that's capping throughput
David Thompson: Even the older BT speed checker thinks I should be expecting around 29Mbs against the 51Mps the 80/20 service thought I should get, so it is picking that number up from somewhere.
Atanu : Ok. the system is showing that this is the maximum speed you will get.
David Thompson: Why did the upgrade process suggest 51mbs for the 80/20 system then?
David Thompson: If 29 is all I will every get, why extend the contract on the basis of the 51mbs?
Atanu : It is the speed available in Exchange. The engineers check the speed in your premises before they provide the Infinity service. But since the line is in the last day of stabilisation, I request
Atanu : You to wait for just 1 more day and check the speed. I will call you tomorrow by teh same time to check the speed.
David Thompson: I'm not clear on this. There are two service levels of BT Infinity yes? the 40/10 service and the 80.20 service?
David Thompson: *80/20
Atanu : Yes.
David Thompson: I've been on the 40/20 system since 2011; The theoretical maximum at time of order was around 30Mps and I've always got around 28Mps on that service. That's fine. Now when I placed the order for the 80/20 upgrade, the theoretical max was 51mps, so I'm pretty certain I would see some reasonable speed increase above the 28Mbs. The fact that I have not seen *any* uplift (even 5-10Mps) at *any* time - especially during quiet periods seems really odd to me.
David Thompson: So I think there is a problem there. If however, it turns out that the prediction system is so really awful and can get is so wrong (when it used to be reasonably accurate), then why trick me in to extended my contract for no reason.
David Thompson: I don't think BT would do the latter, so I'm convinced (still) its just a problem of the migration.
David Thompson: I'll wait another 24 hours, but I don;t think this is going to fix itself.
Atanu : Ok. in that case you need to confirm it form the Billing section as the migration first shows in the Billing. Atanu : I will call you tomorrow
David Thompson: okay
Atanu : And confirm with the Billing team, the Order Management Desk, Customer Options Team that if there is
any issue in the migration.
David Thompson: Just to be clear - you are going to check with the other teams yeah? Not me?
Atanu : Please tell me at what time should I call you?
Atanu : Yes. I will.
David Thompson: Anytime after 7am is fine by me
Atanu : ok. all the teams open after 9 am.
David Thompson: Okay - I'll await your call after 9am; Thanks for your help and patience on this.
Atanu : Thank you for your patience. It is our responsibility to provide you the proper speed.
David Thompson: Okay - until tomorrow - bye-bye
You have disconnected.

Another iTunes upgrade!

In the last 18 months I have upgraded iTunes + QuickTime EIGHT times as I was prompted to. While I do appreciate having the latest software and bug fixes (I'm used to frequent updates as a Windows user!), I have recently noticed that iTunes leaves copies of old iTunes + QuickTime installation files on my computer each time it upgrades! I had to look hard for these files, but found over 400 MB of old files at the following locations...
C:\Documents and Settings\All Users\Application Data\Apple Computer\Installer Cache
C:\Documents and Settings\All Users\Application Data\Apple\Installer Cache
C:\WINDOWS\Downloaded Installations
Why doesn't iTunes clean up its own mess, and since it hasn't, is it safe for me to delete these files myself? Can anyone provide safe cleaning instructions to keep my precious hard drive space safe from these unneeded files?
Thanks!

Hi JOSH
I'm grateful for you pointing out yet another place where our disk space is needlessly being consumed.
Don't know if any of this will help, but here are some observations.
I have noticed several other areas where iTunes+QuickTime chew up far more disk space than seems necessary. However I must refrain from agreeing with your opinions (at least in writing) as on more than one occasion moderators have silenced me (closed threads) for daring to imply criticism (even if constructive).
For another area of questionable(?) space loss, refer to my recent post "Cached files gobbling up space" in the "QuickTime for Windows" forum.
After reading your post, I only found the problem on my XP computer to exist in the first of the three locations that you mentioned. (Around 55 MB.) On my Vista computer, there's 60 MB used in the equivalent folder:
C:\ProgramData\Apple Computer\Installer Cache
So at least in those folders it appears that I am suffering less than you are, though the space is still significant. But here's a possible difference between your situation and mine. Because of this and other issues, these days I refuse to update this software "in place". While it's more work, I will not install a new iTunes and/or QuickTime without first uninstalling the previous version (which, thankfully, doesn't wipe the iTunes library).
Perhaps because of this my computers are only holding the latest install files, while yours may be retaining your whole install history?
As for "How I can get help from Apple", sorry I can't help. In my experience whenever I've asked that, I've had some loyal forum member tell me that these are only user forums, and that Apple does not read them. (Except, it seems, when it is deemed that some of us break rules by appearing to be critical. Or do they silence us without reading?)
Good luck.

Yet Another Soon to be MBP Owner in Need of Guidence

Hello all,
Believe it or not this is yet another post from a college student in the process of purchasing a new MBP who's appealing to the venerable Apple discussion board community for guidance. My dilemma is not that I can't decide on what MBP I want or what features I need, I've already decided on a top of the line model with the 7200 RPM hard drive and a Crucial ram upgrade, it's that I can't decide when would be the best time to make the purchase given the WWDC keynote on the 7th of August. I would like to get the most bang for my three grand but I need have the computer up and running by the twenty-first with Windows installed to run AutoCad. Would you recommend waiting until the 7th to order the computer and see it the MBP's are updated with the hope an updated MBP would be able to get to me in time or should I buy now with the knowledge that I'll be buying a computer that will be updated, but not outdated, soon?
Thanks for your time,
Eric
PowerBook 12-inch 867

I am also a college student... and I was going to wait for the new merom, but I decided against it... I just think the likelyhood of them released before september is unlikely in my head... but you never know... But I looked at it this way... I wanted a MBP bad, despite all the problems I heard about them (my mbp has no problems to this day).... I figured if I waited for the new releases, the only thing that would change is the fact that it's basically a new computer, and with new computers come with new problems... I also figured, the likelyhood of the computers being released before my school started was slim, so I bought it now. I am very happy with my MBP right now, and you have to think of it this way, there will always be upgrades, whos to say that after the merom has been released, something new will becoming after that... I find it less painful to buy a MBP in july, and have the meroms be released months later, then purchasing it in september, and having them be released a possible weeks later... a little less painful, but that's my input, do what you want, I have a 17" MBP , week 26, and I am a happy camper!

Yet another dead mic with Win7 64-bit upgrd - Portege M700

Title says it all. Mics used to work fine on this machine under Windows XP. Under Win7, except as I note below, the mic has inaudibly low volume with any Control Panel Sound settings. I've spent huge amounts of time trying to solve this. After seeing all the similar posts (with no solutions, it seems) from users of many different Toshiba laptops, I'm about to start spreading the meme across the Internet that Toshiba laptops can't use mics.
I started by upgrading to Win7 then adding just the 64-bit drivers I need from Toshiba's support site. No joy. Then I started from a clean Win7 upgrade (64-bit Home) using Toshiba's upgrade script. Nope. Installed latest generic drivers from Realtek. Hmm .. some progress, maybe: now with some Sound settings I can get slightly more volume but the mic input is drowned out by white noise-ish hissing. All right, disable any other sound sources I can adjust: disable Chicony webcam driver from Device Manager. Hmm, now mike volume can get fairly high but the hissing still drowns it out.
Toshiba: At some level, this is a problem between Microsoft and Realtek, I know. But you can help us. MS changed the audio model significantly since Win XP, including (god knows why!) giving up the little audio mixer app that used to let you adjust levels for different sound sources. And Realtek's generic driver doesn't provide one either. So just give us a way to adjust levels for different audio inputs! Maybe I haven't Googled sufficiently and some hacker out there has one, but I kinda doubt it ... if it requires driver-level access as I suspect, Microsoft's new DRM-motivated hammerlock limiting us to signed drivers prevents us from fixing this ourselves. (It also means we can't access our ext3 partitions without extreme measures, but that's another rant.) So CAN SOME TOSHIBA ENGINEER PLEASE LET MANAGEMENT KNOW THEY'RE ABOUT TO DESTROY THEIR LAPTOP FRANCHISE OVER AUDIO ISSUES? Just cut, paste, and forward a couple dozen of these threads. Sure, it's a career risk but (wo)man up to it! Audio really matters to laptop buyers nowadays ... without Skype, I'll have do carry Yet Another Device when I'm traveling. Heck, I've personally bought at least 6 Toshiba laptops over the years and I'm starting to shop for a replacement. Anything but Toshiba, I'm sorry to say :-(
Oh, in case somebody has an idea of something else I can try, the specific model is PPM70U-1KC01DB

Is this yet another problem with 7.5 or is it just me . . .

Upgrade seemed to be fine, at first . . . now I keep getting distortion on songs. It seems to be quite random and just because a song has been distorted when I've listened to it once doesn't mean it will be when I listen to it again! It's driving me insane. Is this yet another bug or have I done something wrong (apart from upgrading to 7.5).

Hi Emlou,
If you have a Windows based operating system such as XP -
It seems to me that you are suffering what I am having the same problem with - the program takes up to much of your computer's processing usage. If you go into your task manager and watch performance as ITunes runs - you will see how much of the total computer usage it is taking at any given moment - that's why your songs are distorted, slowing, garbled, etc - the usage on mine spikes from 11% - 93% AT ANY GIVEN MINUTE! I have no idea why, but I have found that by going to your "Control Panel" and clicking on Quicktime you can adjust audio output to help. Click the audio tab, click Safe Mode Wavout only (checkbox) / Then adjust the "Rate" to 96kHz / Then adjust the "Size" to 16 bit. Close that and shut down and restart Itunes - it might help a little for you.
Maybe someone out there can help us find out why we are suffering with all the CPU usage trouble and how to adjust that spiking.
Thanks!
Paul

Display hints, custom format method in VO, is there yet another way?

Did you experience the same and had a solution?
Hi,
I am using JDeveloper 10.1.3.4 and looking for yet another way of customizing the display of an attribute of a view object.
I have two tables: BILL and AWARDS, with composite foreign key relationship (on the LDAP_UID and TERM fields) between them, as illustrated below.
The BILL table:
NAME       LDAP_UID    TERM   CREDIT_HRS
Tom Smith tom.simth   200902       12.5
Jane Lopez jane.lopez 200906        4.0
The AWARD table:
LDAP_UID    TERM SOURCE     APPLIED
tom.smith 200902 Perkins     2000.00
tom.smith 200906 Direct      1300.00
jane.lopez 200906 CN           500.00 At the business data model level, this is master(Bill)/detail(Awards) relationship. Bill is dragged from the data control palette to the page and displayed as a form, and Awards is dragged to the page as a table. When tom.smith logs in and chooses the 200902 TERM, the master and detail are joined on tom.smith=tom.smith and 200902=200902, so the $2,000.00 of Perkins loan is retrieved for him:
Name Tom Smith
Term 200902
Source    Applied
Perkins   $2,000.00That works fine but not user friendly: the values in the TERMS column are a bit cryptic and need to be displayed in plain English, i.e., 200902 should be displayed as "Spring 2009" and 200906 as "Summer 2009". The display hints in the VO can not handle this. The only other way I know is writing a method in the Row class of the VO to do the translation. And this is the result:
Name Tom Smith
Term Spring 2009
Source        Applied
No rows yet   Obviously, "Spring 2009" is used not only for display, but also for joining the master and detail tables. Of course "Spring 2009"!=200902, therefore no detail is retrieved for the user.
Question is: is there yet another way to customize the display, that does not affect the join of master and detail tables?
Many thanks for your help!
Newman

Hi, Chris,
That works!
I found the chapter where transient attribute is explained and an example is given creating a transient attribute in the entity object. It turned out that transient attribute works both in entity object and view object. I did it in the VO and it solves my problem.
I spent hours of time before posting that question, trying two different ways but neither worked. Your one sentence saved me a lot of time. I do appreciate you help very much!
Truly,
Newman

Yet another export issue with Aperture 3

Judging by a search of topics, there seem to be a myriad of problems associated with getting files out of Aperture, some of which represent occult setting issues, others which seem to be actual bugs. I've run into an issue which seems to defy categorization, and I'm not sure if it's me doing something wrong, or if it is actually yet another bug with this software. I've been an Aperture user since 1.0 and I have to say the current version I'm running (3.4.3) is by far the worst yet. Anyway, enough whining. Here are the issues:
I'm running Aperture on a 6 core Mac Pro with Lion 10.7.5. There are two thing happening.
1. Exporting JPEGs is INCREDIBLY slow - perhaps as long as 4 or 5 minutes for a 3MB file.
2. This is the one driving me batty right now. Tried exporting a batch of images as JPEGs at the 50% original size setting. The master files are large 16 bit TIFF images from Nikon D800 RAW files, post-processed in Nik HDR Efex Pro 2. They are 80-100MB in size. When I export the images to a file on my Desktop, it consistently exports 6- 10 KB thumbnails. I've checked and rechecked my export settings and can find nothing amiss there. Has anyone else had a similar experience? Could the view I'm working in have anything to do with this? I work 95% of the time in split view.
Thanks,
Russ

I agree that there re a lot of posts about exporting, but a very large number of them refer to the same thing, and it's not a bug, but rather a misunderstanding.
For instance:
Tried exporting a batch of images as JPEGs at the 50% original size setting.
Okay.
The master files are large 16 bit TIFF images from Nikon D800 RAW files, post-processed in Nik HDR Efex Pro 2
Not relevant.
They are 80-100MB in size.
Not relevant either.
Why?
Because size refers to the dimensions of the image. So a 1,000 x 1,000 pixel image exported at 50% will turn out as 500 x 500 pixels.
Were you expecting a jpeg between 40 and 50 MB? That's Jpeg quality or the amount of compression applied to the image. And as you're compressing a lossless format (tiff) to a lossy one, and one with an aggressive compression algorithm, he resulting Jpeg, even at high quality, will be much, much smaller, more likely in the 6 - 8 MB range.
That's the nature - and indeed the point - of Jpegs.
So, if you're getting 6 - 10 kb images, you're exporting at a very low Jepg Quality.
This may also explain why it's taking so long to export. Getting rid on 99.99% of the data and compressing into 10kb is always going to take time.

Carbon - yet another terminal emulator

What is carbon?
Carbon is yet another terminal emulator aiming at minimalism, speed, functionality, and aesthetics. As an added bonus, the code is very modular.
Carbon is built on xcb instead of Xlib. There has yet, to my knowledge, a terminal emulator built like this. This should prove to provide a faster and more responsive terminal.
Features
* Support for managing different colour themes.
* Ability to install custom escape sequence handlers.
* Daemon mode much like urxvt, possibly with some degree of detaching/reattaching support.
While I haven't figured out how I'm going to handle configuration, I will utilize custom escape sequences to control certain settings. For example, unless I find it unsatisfactory, carbon will provide a shell script for theme changing/previewing, relying on escape sequences to tell the terminal what color theme to use.
The code it somewhat suckless inspired, it will utilize a config.h file by the time its done. However, I have a somewhat bigger aim on making carbon modular than most suckless projects. The terminal emulator back-end should be easily reusable other projects.
Current status:
* I can create a tty and read and write from it.
* I can parse CSI escape sequences (but I ignore them for now)
* I can read keypresses from a windows and send the appropriate character to to the tty (at time of posting, this is not committed to repo).
Not really worth running as it doesn't draw to the screen yet, but its getting there.
Thanks to:
* st, madtty: This project was largely written looking at how they did things; my code ranges from very similar to blatant rip-off.
* Awesome: I gutted their keycode->keysym->string code to get input working. Kudos for adopting xcb.
Heres a link to the project on github: github.com/simongmzlj/carbon
Thanks for your time. Any comments, ideas, or criticisms would be appreciated.

Sorry, I really wasn't very clear, and I'm not positive how to say it. I'm perfectly happy with being able to scroll through history. That's a useful feature. But consider this situation: You're checking out the git man files. This gives you a page far longer than your terminal is, and you work your way down to the command you wanted to check out. Then, when you quit, I prefer if the info stays on your screen instead of removing the git man page and going back to what you had before calling man. Hopefully that makes sense. If not, think the default behaviour of screen (prefered) vs. xterm.
