BizTalk: Bad Things: What is bad about usage of Direct Binding?

Hey guys,
I started series of AQ about BizTalk. Please, feel free to be impolite in this discussion, if you are frustrated about some implementation pattern in BizTalk apps, or about something you see frequently in code.
Direct Binding, it looks pretty cool, smart and cool again! But is it always so? Have you ever seen how awfully it is used? Please, share your knowledge!

One thing:
Say, we have an orchestration with bounded send port. We cannot unenlist a send port if an orchestration is still enlisted. We've got an error:
Which prevents us from leaving this orchestration without subscriber (this send port). 
If we use direct bounded port here, the result would be unlovely. We unenlist the send port. There would not be an error, the messages sent by orchestration would be suspended with "no subscribers" error. 
Binding prevents us from this error, it forces us to keep subscriber (the send port) running if publisher is running. 
So in cases, when we want messages be passed from an orchestration exactly to this send port, the direct binding is a bad idea.

  • What's So Bad About It?

    What's so bad about iPod Linux. I am thinking of getting it but it doesn't support Nano but I will risk it anyway. Before I do please explain to me why everyone on this forum despises it.
    -confused

    I would strongly recommend to stay clear of Linux for the iPod, for the following reasons.
    1) iPod Linux voids the Apple warranty, so if anything went wrong (which frequently happens), you would have to fork out to get a repair/new iPod.
    2) Linux makes the iPod run totally differently than it used to, i.e basically making it not an iPod, but a small Linux. As Chris CA stated, "you can fill your car up with water, but it still isnt a hot-tub."
    3) Many users have reported "bricking" their iPod after installation, leaving them with a rather expensive paperweight that Apple will not touch.
    4) The Linux website also states that even they do not support Nano installations.
    5) Videos shown through Linux on a Nano are very poor quality, since its extremely difficult to get a video file small enough to fit, the screen size is tiny etc.
    6) If something went wrong, no support could be given on this forum, as it is against the Terms of Use.

  • What's so bad about Firefox 3.6.28?

    I'm feeling a bit Push-Shopped to buy a new computer here. . . apparently Firefox's recent upgrades don't work best on a G4 Power PC chip.
    So the solution is to run the old Firefox or find a more accomodating browser!
    My minimac works perfectly, runs well and does even more than I ask, or need, it to do! Buying new hardware seems the extreme solution here.
    So what's bad about running the older Firefox version?

    You can download TenFourFoxG5 from here:
    http://www.floodgap.com/software/tenfourfox/
    Now for the intersting bit: TenFourFox, like Firefox, does not support most plug-ins. Unless you are prone to headaches (in which case don't) you can read about that here:
    http://code.google.com/p/tenfourfox/wiki/PluginsNoLongerSupported
    But there is a workaround!
    Open TenFourFox and type in the address bar: about:config (no spaces) and click return. This gives you a warning that it might harm the application. Ignore that and click on 'I'll be careful, I promise' and you get the config file that you can edit - with great care.
    Look/search (scroll down) for: tenfourfox.plugins.enabled
    Set it to true. (Double click it to toggle it)
    Now close TenFourFox, open it again, and Flash will now work, as it now uses the plug-ins that Safari has stored.
    I am using Flash 10.1.102.64 in TenFourFox and it works just fine.

  • I READ A LOT OF BAD ABOUT THE NEW O.S. IF I DON'T LIKE IT HOW DO I GO BACK TO 10.8.5  I AM COMPETENT BUT NOT A SUPERGEEK OR EVEN A PRO SO K.I.S.S. WOULD BE GOOD

    I READ A LOT OF BAD ABOUT THE NEW O.S. IF I DON'T LIKE IT HOW DO I GO BACK TO 10.8.5  I AM COMPETENT BUT NOT A SUPERGEEK OR EVEN A PRO SO K.I.S.S. WOULD BE GOOD

    Make a bootable backup of your current system before upgrading or make a new partition on your hard drive and install the new OS on the new volume. Now two more things for someone who believes they are competent:
    1. Don't believe everything you read on these forums. Only users with problems post here. Millions of other users don't post here because they manage not to have problems.
    2. Don't use all CAPS. That is considered shouting. Shouting is bad netiquette. Please use mixed case.

    The program is for replacement since Apple does not repair iDevices...you take your non-working or damaged iPhone to an Apple store genius bar, or send to Apple service, and they provide a refurbished unit as a replacement, for a fee, of course.  You will have to talk with Apple to see if you get all components or just the iPhone replaced.
    With AppleCare+ you can have two out-of-warranty replacements for a cost of $49 each.

  • Bad CPU usage

    Hi I just installed 10.5 when using compressor the cpu usage is almost down at 10%. Has anyone similar problems?
    Thanks
    Michael

    No - it is shared between cores.
    your processor has 2 cores - each core works with each other - so if you're using 100% or 110% - each core is using either 50% or 55%...
    see image below - that is from my MB Air - each core is using a percentage of what the total CPU usage indicates.

  • What is it about Apple???

    I realize that this question may not belong in this discussion forum and if someone knows about any other forum that is more suitable for this types of questions I would be very grateful if you could give me the name/link to the forum.
    I am currently doing research for an article regarding brands and customer loyalty and after reading through a great number of articles, news releases, blogs, etc. I realize that the customers of Apple are not like other customers. They are probably some of the most loyal people I've ever read about. No matter what mistakes Apple may make, the customers are always there to support them and every time someone says something bad about the company, there are always one or more Apple-enthusiasts that steps forward to defend the brand. As a person who do not own any Apple products, I'm having a hard time understanding this extreme loyalty and I therefore need to ask: what is it about Apple that is so great? Is it just the great products that make the customers so loyal or is it something more than that?
    I'd be extremely grateful for any replies I may get.

    Ckristof ~ In this _1995 interview_, Steve Jobs explains the type of creative people behind the original Mac. And at the end of the quote below, Jobs reveals something special those people put into Apple's products — and presumably still do. ...Could it be that which is the +"something more"+ ? ... Could it be that which indirectly makes Apple's customers so loyal without them really understanding why?
    Interviewer:
    And the artistry is in the elegance of the solution, like chess playing or mathematics?
    Steve Jobs:
    No. I think the artistry is in having an insight into what one sees around them. Generally putting things together in a way no one else has before and finding a way to express that to other people who don't have that insight so they can get some of the advantage of that insight that makes them feel a certain way or allows them to do a certain thing. I think that a lot of the folks on the Macintosh team were capable of doing that and did exactly that.
    If you study these people a little bit more what you'll find is that in this particular time, in the 70's and the 80's the best people in computers would have normally been poets and writers and musicians. Almost all of them were musicians. Alot of them were poets on the side. They went into computers because it was so compelling. It was fresh and new. It was a new medium of expression for their creative talents. The feelings and the passion that people put into it were completely indistinguishable from a poet or a painter. Many of the people were introspective, inward people who expressed how they felt about other people or the rest of humanity in general into their work, work that other people would use. People put a lot of love into these products, and a lot of expression of their appreciation came to these things. It's hard to explain.

  • This is what I hate about Mac...

    This is what bugs me about running mac!  I have sent various crash reports to this forum (A support forum hosted by APPLE).
    No one has ever pointed me in the right direction.  I don't know who else to ask?  Is there anyone?
    Lots of people seem to think their Mac is great.
    Mine keeps crashing!
    If I want to run Logic 9 I have to spend $2500 because I would need a New Mac pro.
    If my Mac didn't give me so much grief I would spend the money on a new one.
    I am convinced that I should get a PC! It must be more stable!
    grrrr

    I only see one post about crashing, and it got responses but you never followed up.
    Like pancenter said, try reinstalling the latest version of 10.5 from the combo updater.  I would do whatever hardware tests you have available,  it's possible you have bad memory or a hard drive starting to fail.
    If that doesn't help, I'd try running Logic with no hardware hooked up and no third party plugins.  If you still get crashes that points to a problem with Logic, if not start adding those back in a little at a time since one of those may be causing the crashes.
    In your other post you mentioned switching to Cubase.  They don't support G5 any more with their latest versions, only intel.  I don't who if any of the audio devs is still supporting PPC, if you want the latest software you may need to get a new machine at some point.  The good news is that even an iMac or laptop will probably run circles around the machine you have now.

  • I purchased a used 2008 iMac. And although the previous owner said he deleted all of his information his iCloud account is still the primary. I don't have a clue about what to do about it. I signed him out and logged in with my info, but still no go.

    I purchased a used 2008 iMac. And although the previous owner said he deleted all of his information, his iCloud account is still the primary. I don't have a clue about what to do about it. I signed him out and logged in with my info, but still no go. Is there any way to eliminate his iCloud account and make mine the primary without rebooting it back to factory settings? There was an update, I believe, that I couldn't install because i didn't have his password that is what made me aware that his acct. was still active. I don't know what to do. Any help is greatly appreciated. Thank you.

    Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
    The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
    How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
    It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
    1. If you don't own another Mac
    a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
    b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
    To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
    c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
    d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
    2. If you do own another Mac
    If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
    3. Partition and install OS X
    a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
    b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the  Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
    c. An unusual problem may arise if all the following conditions apply:
              OS X 10.7 or later was installed by the previous owner
              The startup volume was encrypted with FileVault
              You're booted in Recovery mode (that is, not from a 10.6 installation disc)
    In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
    d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
    e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
    4. Other issues
    a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
    b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to  authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
    c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

  • Does anyone know what to do about iCal colors changing.

    Does anyone know what to do about iCal colors changing.   Ever since ios7 came out I have many problems.  I kind of feel like Apple has become Microsoft at twice the price??  Anyway, today all my calendars (iPhone, iPad, iCloud and on my Mac) all changed colors from the customer colors I had set.  I have about 5 calendars.
    I was able to change them back on my Mac, my iphone and my ipad, but not in iCloud.   Once each of the ones I changed updates / syncs it reverts to the incorrect colors again.  I have tested back and forth, and it is definetly coming out of the iCloud.com.  The web site will not let me chance colors, so once it updates / sync, all my other devices and calendars sync to the purple in iCloud.
    I could go on and on about my frustrations with the apparent lack to testing, and the irony around Microsoft and their "bugs".  It is more important that I find a cure, as this is really annoying.
    Has anyone else seen this today

    Don't spend a lot of time trying to change it. It's an iCloud problem that's happened before, and when it happened in August it went back to the correct colors in a few days. Just be careful when you add new items to the calendar to use the right calendar (even if the color is wrong), otherwise you'll have things out of synch when the correct colors come back.

    One thing that is mentioned, but not really emphasized, is that the zooming when opening and closing Apps is now gone when the reduce motion setting is enabled. I guess too many people where claiming sea sickness and Apple wanted to avoid lawsuits.
    Now the nay sayers will have to refocus their efforts and complain about the font and the icons.

  • OK, what is it about G4 towers suddenly w/o power?

    I got my dual Gigabit Ethernet G4 tower from work when they got rid of Macs about 4 years ago (keep hoping they'll change their minds). When I first got it I had the typical no power problem and a new battery solved the problem (but I had to order it from OWC, the one I got at a local store didn't work).
    Right before Christmas we shuffled furniture around in the family room and unplugged the Mac. Now it's dead again. I've tried two different new batteries (one from OWC), I've done the simple reset and the sit for 30 min reset and the sit overnight reset and the take out all the ram and the cards reset. Still nothing.
    Now, it appears I'm getting something from the power supply because when I had everything plugged in, the monitor was showing that it was getting power. Does that mean that it's more likely the motherboard than the power supply?
    I know it's had a good long life, but I'm really sorry to see it go. I got a good deal on a core2 duo Mac Mini. I think the g4's likely dead; if the problem is the power supply, it's going to be a bear (and $$$) to replace, and although I see motherboards on eBay for a good price, I know I could get that in, struggle to figure out how to replace it, and the darn thing still might not work. Plus the motherboard I just purchased would also be like 8 years old.
    So...what is it about G4 towers and suddenly not starting up? I see this problem frequently on the support boards. I love Apple (right now I'm stuck on a Vista laptop and...ugh), and I know that this tower had a long life, but doggone, why do they just suddenly drop dead without any warning?

    If you have a meter, unplug the AC power plug from the wall and wait a minute, then measure the battery in the holder, working. If you do not see 3.2 Volts or higher, the battery, regardless of its history, is not working.
    After fiddling with any Hardware, you should press the tiny reset button for a quarter minute \[with the Mac nominally off, but the AC power plug plugged in]. Then wait at least five seconds before proceeding. Avoid momentary presses, they can crash the microprocessor that controls the clocks and drain your battery in a day. If nothing seems to change, do the procedure again.
    If you still have no response, disconnect the drives, remove everything except the processor and memory, do a reset, and try for a startup chime.
    If no chime, use this diagram to look for Standby Power on pin 9 of the main DC power connector:
