Java may be slow, but this guy ain't!

well, they have the marker lines for that purpose, so the guys in the air, who can't use radar from above, can measure the time between fixed distances. Of course, it might have been less then 205.11 exactly, but still would've been pretty darn fast.

Desktop Java May not last but Enterprise Java will

I have realized that there seems to be a kind of a futile effort battling .NET on Windows Desktop. Its really crazy having put so much effort learning desktop java only to realize that .NET may eventually topple it.
What gives me joy anyway is the general response to Enterprise Java. Its seems to be very strong especially when coming from the perspective of the the growth of linux and the security model of its architecture. I will advice any new java newbie to just start migrating to Enterprise Java as soon as he starts picking up in java otherwise the effort to overthrow .NET on windows desktop may be toppled eventually. But i think that Desktop Java Should be empowered more for Linux Platforms this days.
I dont know if there is a contary opinion but i am raising this issue becuase I have applied for so many IT jobs only to realize the are looking for .NET or VB when it comes to Desktop Applications. Also I will also suggest that IDE builders community shouls also support the growth of easy-to-use IDEs for J2EE so as to encourage new user to come in.
Cheers

I'm a web developer for 4 years, use coldfusion and over the last year started to migrate over to j2ee,
I'll admit it a learning curve at the start from procedural to OO, however I am the only java developer in
the company, the rest are VB, and everything Microsoft. I have to admit a hate it, DLL hell as far as COM
is concerned.
I don't know the difference between .NET and the old school VB stuff, but our guys are not singing off the .NET hymn sheet. If anything they are swayed by the power of java and the open source projects like apache coocon,James,POI,AXIS,Jakarta Tomcat the list goes on. However they all still develop in old VB, which quite a lot of companies are still doing.
Its very expensive to buy is it not.
I hate everything to do with Microsoft personally, "let me sell you a server, and I'll sell you the other half".

Outlook 2010 - User tends to open many emails at a go but this may slow down the machine.

Hi,
My user tends to have this work habit of opening 8-10 emails at one go. She view this way of working as more efficient and faster. But this means that if outlook crashed, all the emails will be close as well, and this way of working tends to slow down the
machine.
Is there any way Outlook can users to open multiple emails without hording CPU page milage?
Thank you.

Hi Josh,
Slow Outlook can be also harmful for your database and there are numbers of factor which slow down the MS-Outlook like:
* Third Party Plug-ins
* Slow internet connection
* Antivirus/ Firewall Programs
* Corruption or Error within Outlook
So always try to open Microsoft Outlook in safe mode whenever you stuck in such problems.
How to optimize Outlook performance:
* By Disabling add-ins
* Check default account settings
* Disabling Scanning programs
* Scanpst.exe (Inbox Repair Tool)

Need a lot of custom JComponents, but Java just too 'slow', other Solution?

Hi folks,
first of all i'll try to explain my problem (although my english is quite bad)
We're programming a tool for visualising graph algorithms (df search, strong connected components, transitive reduction etc.) For that, we got a drawing area (derived from JLayeredPane) which contains the Nodes and the Edges of a graph (for all that don't know what a graphs is, just imagine these nodes as numbered circles, and the edges as directed lines from one node to another).
Both parts (Nodes and Edges) are derived from JComponent, because a) need MouseEvents on these Components and b) we need the ability to add them to a container (like JLayeredPane)
An absolute requirement is that you can directly click on the edges (to mark them, or delete them etc)
Another point which needs to be mentioned, the edges maintain a (invisible) polygon which lies around their line, this polygon is sensitive for mouseEvents.
Now there are two main problems:
* all these edges have (due to JComponent) (possibly) huge invisible rectangles (the only thing that really matters is the line from one corner of this rect. to the other) ...so if i got lets say a graph with 10.000 edges, there are a lot of edges that overlap (nearly 10.000 :) ) ... but only the Edge-object on top receives the MouseEvent (but perhaps the user wanted to cklick a edge that lies below the top-edge!) .. at the moment, the program looks at all edges below that which received the MouseEvent and checks wether the 'mouse'click' hits a polygon, If it does, the top edge dispatches the MouseEvent to that edge. (furthermore, due to the depth-order in a Layer of a JLayeredPane, we only need to look at all edges that are really below the egde that received the mouseEvent)
This all works great for 'small' numbers of edges (approximately 1000-2000) but with a rising number of edges this attempt gets slower and slower (it takes 1-3 seconds to evaluate a single mouseclick on a Sun Ultra 5/333)
* the bigger problem is, that if i got 10k+ JComponents in a Container Java gets really slow, just adding these 10k JComps. (to the JLayeredPane) takes some minutes?! Furthermore java consumes up to 200+ MB main memory in this situation.
One solution we are currently thinking about is to implement these edges as 'pure graphics'-objects (for example the Container just draws all edges).. this probably solves problem # 2 but # 1 gets even worse (no depth-order, some more coordinates hassle)
So, i hope someone can give me a hint for this problem or someone has had a similar problem before and has a good solution? (if the problem isnt clear, just ask)

I worked on an application once that had a similar structure as yours, but we were only scaling up to about 1000-2000 components. The problem that we identified (and that you have, no doubt, also identified) is that you are searching all of the child components on every hit test/overlap test. What we did was to subdivide out outermost container so that it had a couple of dozen children, each of which then parented some of the original child components: this cut our search space for every hit test dramatically. We had the advantage of having collections of child componenents that we knew would not overlap so our first level containers did not overlap -- you may need your first level containers to overlap, but even with this, you'll still be able to much more quickly identify components in the immediate region that should be checked individuall.

I want to use Back to my mac. When I try to turn it on, it says "Back to My Mac may be slow because more than one device on your network is providing network services. Turn off NAT and DHCP on one of the devices and try again." How do I fix this?

Not sure if I am doing this right. This is my first time in the support community.
I imagine what I put in my heading was supposed to go in here.
I want to use Back to my mac. When I try to turn it on, it says "Back to my mac may be slow because more than one device on your network is providing network services. Turn off NAT and DHCP on one of the devices and try again. See the documentation that came with your device for information about turning off network services"
Does anyone know how I do this? I contacted my ISP (Telus in Canada) and they did not know anything (not that they usually do).

Why do ISPs insist upon making things so difficult for their customers?
If you cannot get them to understand that you would prefer to use your own router over their piece of cheap junk, perhaps the information in the following will be useful:
http://keithbalomben.wordpress.com/2012/03/29/telus-actiontec-v1000h-hacks-and-i nformation/
Scroll down to DHCP Settings
You will need to log in with proper "technician" credentials. They are provided in the above link as
Username: tech
Password: t3lu5tv
... but these may or may not work. Try it, and if you cannot get anywhere at least now you know what to ask Telus to do in return for your business.

I can no longer burn CDs - "may be incompatible with this disc burner, try slower speed, try another make of disc" Still doesn't work

I can no longer burn CDs - "may be incompatible with this disc burner, try a slower speed, try another make of disc" Tried that, still doesn't work.

Try a free burning utility which allows you to turn off the laser for test burning (so you don't waste media). Try burning a test CD outside of iTunes. If it works it's iTunes. If it doesn't work it could be computer software or hardware but then we know how to proceed.

Hi, i am having an issue with a basic motion scroll effect.
I already watched and read every tutorial out there regarding this topic and even tried the adobe chat support, but the guy on the other end of the line disconnected me…, probably he didn't understand what i wanted from him because english is not my native language, so a will try to be very, very clear about this one..
please note, that i am new to muse, this is my first project ever.
my idea is as following:
when the customer comes to our companies site, he just sees our logo on a white Background. the logo consists of, say, four elements. when the customer scrolls down, the logo starts to disassamble: first the first part of the logo flies out the left side of the site, then the second part of the logo vanishes down, then the third part of the logo flies to the right, then the fourth part of the logo flies to the top and out of the customers view. given what i have seen, it is possible to do that….
so…..
now i have the four parts of my logo imported as png files into muse and assembled them in design view to build our companies logo. I select every one of the four parts and go into the scroll effects tab left beside the layers tab. first i enter the same values for every one of the four parts: initial motion: 0x and 0x again for the left and right motion; key position ( t-handle) : 0px; final motion: 0x and 0x again for the left and right value.
now i hit "preview".: the logo is "pinned" at the correct position, i can scroll but the logo stays where it is. so far so good….
now i select all the four elements again and go to the scroll effecs tab. at "final motion", i click the down arrows and enter 1x. I hit Preview…
when i am scrolling down the WHOLE logo goes down…. so far so good.
NOW i want the first part of the logo to go down, THEN the second part to go left, THEN the third part to go up, THEN the fourth part to go right.
so i select ONLY the first part, go to the scroll motion tab, at "final motion" i click the left arrows, then i enter 1x.( the up-down value, i set to 0 again).. i hit Preview…
the first part of the logo goes left as soon as i start scrolling, the other three parts still go down at the same time…
NOW i want the second part of the logo to start moving, when the first part has left the scene, not at the same time as the first part.
SO I SELECT THE SECOND PART AND DRAG ITS T-HANDLE (KEY POSITION) DOWN TO, LETS SAY, 200PX. SO IT STARTS MOVING ONLY AFTER THE CUSTOMER HAS REACHED THAT POINT, RIGHT?
BUT WHEN I PREVIEW THAT ****, THE LOGO IS NOT TOGETHER ANYMORE, THE SECOND PART IS FLOATING ANYWHERE ELSE BUT WHERE IT SHOULD BE…..WTFF????
short: when i move the t handle, the initial position of the object changes. thats what i said to the adobe employee, but he said, that thats the expected behavior….
but if thats so, how can i have my four parts correctly together, so they form my logo, but with different t handles, so that they all start to move at different times??
Pleeease help me, i am dying of frustration here…..:( that behavior cant be right, right?
Thanks so much to everyone who actually reads this post and tries to help…….
All the best,
Niki Lapan

Thank you so much for helping,
But i really wonder how you did that. did you always switch between design view and preview view, then change the key position for 2px then switch back, to align the four letters? because i imagine that can get really frustrating, if you have a logo consisting of 58 parts instead of 4!:)
Anyway thank you very much for your time and effort!!!!

I own a 13-inch MacBook Pro and for the past day, my wifi on my laptop says I only have two bars of connection and is running very slow,but all of my other devices such as my iPhone and iPad are connecting perfectly to the wifi. How can I fix this? I have tried to shut my laptop off and let it rest and I have also re-started my wifi router three different times. Someone please help me with this problem so I can begin to use my laptop again as I take it to school and use it for class.
Thanks so much!

FCP, and all software on OSX, has a few different "preference" files (the extension is .plist), which store all your user settings. Each time you resize a window, change a setting, anything, this file is re-written. Kinda easy to see how they would become corrupt every now and then.
-Close FCP
-Navigate to User>Library>Preferences and delete com.apple.FinalCutPro.plist
-Navigate to User>Library>Preferences>Final Cut Pro User Data and delete Final Cut Pro 5.0 Prefs
-Empty your trash
Relaunch FCP and see if that worked.
Download FCP Rescue to make this process easier in the future. When you have FCP running really smooth, open FCP Rescue and create a backup of your preference files. If it starts acting wanky, just run FCP Rescue and Restore your backup preferences. Works really slick, and it's free.
EDIT: Or use the really simple explaination that X posted as I was typing.

HT4864 Thank you! This may sound lame but are these instructions for the blackberry? I'm receiving iCloud emails without problems on my MacBook Pro and I'd rather not mess w/ settings there.

You don't need to start a new thread to continue a conversation, you can just tack onto the original one. The settings I referred you to are for the Blackberry, since that's the device which is not receiving mail: anything which is working can be left alone.

When entering my phone serial number it shows "We're sorry, but this is a serial number for a product that has been replaced. Please check your information and re-enter your serial number. If your information is correct, you may need to contact us."

Hi,
I had purchased an iPhone 5 last month and got the OS updated to iOS 7, yesterday.
The data cable was of very bad quality and when I took it to the retailer for replacement, they said that its not covered under the one year warranty.
Secondly, I have also been experiencing network coverage issues with this phone. So, I decided to contact apple care through the web. When entering my serial number/IMEI it says, "We're sorry, but this is a serial number for a product that has been replaced. Please check your information and re-enter your serial number. If your information is correct, you may need to contact us."
Does anybody have any idea what the reason behind this could be.
- First time with iPhone and frustrated.
Briju

If you purchased the iPhone from Apple or an authorized Apple reseller,
contact them for assistance. If you purchased elsewhere, go back
to that retailer and get them to give you a new iPhone or your money
back.
If you have checked the serial number carefully and re-entered it
and that gave you the same error message, contact Apple if purchased
from Apple or authorized retailer; otherwise you have been scammed
and need to pursue the matter with the business you obtained the
iPhone from.

I bought my Iphone in the apple store, but I d like to unlock it since I'm living in Brazil, what can be done? I know that it's possible to switch carriers, there was this guy that told my mother that it is possible to do it online and for free....

Does anybody know how to switch carriers of the Iphone, I bought it at the apple store, there was this guy that told my mother that he said that it was possible to do it online for free, but I can't find it!! does anyone know what to do??

Carriers lock phones. Only Carriers can unlock them. Contact the carrier to whom your phone is locked. See if they allow unlocking, and if they do, what the qualifications are.

I think the easiest way to do this is to have the EyeTV app running in one user account and sent via HDMI to the TV, and use a separate user account for Screen Sharing. Both logins can be active at the same time and with Lion you can connect via screen sharing to which ever login you need.
With regards to the Mac video resolution changing, when it is not the current input on your AV receiver. This is 'normal', if the Mac sees no signal it drops down the a lower level. What you need is to buy a HDMI Detective Plus which tricks the Mac in to always seeing a signal and hence it will not drop down the resolution. See http://www.gefen.com/kvm/dproduct.jsp?prod_id=8005
The Mac mini does have an IR receiver. This can be used with the EyeTV app, iTunes, and similar. Yes I believe EyeTV would run for prolonged periods quite happily, it is has been around for a long time and had most of the rough edges polished off. However one issue you will have to deal with is that it does not automatically update its program guide data. For this you might have to write or modify an AppleScript. Elgato support or their user forums will be a lot of help.
You can set EyeTV to convert recordings to an iTunes (Apple TV) compatible format and then delete them from EyeTV.
The HDMI Detective should solve your handshaking problems.

This may seem basic, but I just discovered that I do not have a share button (the thing with the little arrow popping out) to the left of my address bar on my Mac. I do have one on my IPad and really like it. Why don't I have this on my Mac?

This may seem basic, but I just discovered that I do not have a share button (the one with the little arrow jumping out) to the left of my address bar on Safari for my Mac. I do have one on my IPad and use it often. Can anyone tell me why my Mac is missing this icon and how to get it? Thanks.

Going from Lion to Mountain Lion is considered an upgrade (because it is not free), not an update.
So yes, given that you have Lion, you are up to date. But if you can, you might consider going to Mountain Lion for a fee.
Here's what you need to do the upgrade:
