Opinion needed

hi all, im in the midst of trying out jsp and relatively new to java. i tried to copy several files into a temp folder where the client can download the files from the jsp site (not the original copy), and i was thinking what if i want to delete the temp folder once the user finish downloading, how do i know that the user already completed the downloading of the files? :)
thanks in advance.

phone him up and ask him?oh, very clever, but what if the guy is using a dial-up connection ? How will you phone him ?

Your opinion needed

I ma doing gcse art and design graphic design in school. I always do my graphics in photoshop but had to do it in firework that day (dont ask!!). Plz tell me ur opinion of it, be honest!! this is my first ever try on fireworks, i never saw or used it before!!

Well, my design style is very different! I like more minimalist looks and I do Web sites that need to appeal to broad audience ranges. I wouldn't want to hamper your vision in any way.
I think your bright pop-art-style colors are a good fit for mp3 player packaging, though. Consider who the people would be that would buy an mp3 player. Many of them are your own age, so designing for yourself is designing for your customer base.
If you're just doing work for class, then you can probably pull images off the Internet, because only your teacher will see it. In general, however, no. In most cases, when someone makes an image (no matter how), they own the copyright and if you take it and do something with it then you've created a 'derivative work" to which the original image creator still owns the copyright. If you plan on entering anything in a contest or selling anything, then your work should be original from the start, or use base imagery you have permission to use.
Some images are "public domain" and available for you to use. Putting an image on the Internet does not make it public domain. The creator of the image must specifically say that he or she is releasing it as a public domain image.
Some reading for you:

http://www.google.com/search?hl=en&source=hp&q="public+domain"+image+"new+york"&aq=f&oq=&a qi=g-p1g9
And, all this copyright stuff applies to any artwork you create, too. Nobody can ever take it away from you; you have to release your work (or, if you're working for someone else, the copyright may be theirs).

Recovering cold backup - running in circles - part 2 -Second opinion needed

Hello all,
Here I'm again but this time not to ask for a complete solution where I have to do nothing but a second opinion and some help in solving.
In the thread [Recovering cold backup - alter database open failing - running in circles |http://forums.oracle.com/forums/thread.jspa?messageID=9663720] , I was trying to recover a database (I still am) for one of our clients.
Since then a few things have changed, from our client we have no received the installation media for their database software: Oracle 10.0.1.0.2.
I have installed this on a Linux, an opensuse while they used a RHEL 4, placed the database files in the a similar map structure as theirs and made sure that all the ORACLE variables were correctly set, we have also received the pfile and I made the corresponding initfile from.
I start sqlplus / as sysdba
Mounting the database no problem.
Trying to open the database I receive the following error ORA-01207: file is more recent than controlfile – old controlfile, the error refers to the Datafile 2: '/home/oracle/product/10.1.0/oradata/orcl/undotbs01.dbf'.
Their is no corresponding error message in the alert log, well their is but it doesn't really give me the information I was looking for.

So that could mean that they've just taken a copy off the files without offlining the database first, anyway to confirm this.
I've come to a point where I have not an immediately clue of what to do, some help even a little push could be helpful.

**URGENT**Second opinion needed

Hey,
Currently have Iphone 3g, want to get the new blackberry bold. Prefer blackberries. Just would like some feedback on why to switch or not to switch,advantages vs disadvantages that I may not be thinking about. Have done research just need a general second opinion to fully make up my mind.

In general when one reads peoples opinion of the iPhone you hear this:
From those that traded up from basic phone to their first smart phone, the iPhone kicks bu*t.
For those that have had a smart phone (particularly Blackberry) they find the iPhone lacks in some of the things they had access to via owning a smart phone (big one is email options and how it works).
You hear mixed reviews from those that have had Blackberrys and used them to their full potential (some people just had them to had them so find the iPhone fine).
So you said you like Blackberry...I am assuming you had one and are missing some features of it. Thus the choice is based on your needs.
Those that want a richer corp. email experience find the Blackberry better.

Opinion Needed on Atlona AV Toolbox CDM-660 Standards Converter

In the course of day-to-day transfers of VHS to DVD I am getting a mounting number of requests to convert PAL to NTSC. I have the Nattress plug-ing and I am familiar with Compressor's ability to transcode, but both are rather time intensive. As a result, I am looking at hardware based option that can give reasonable results in real time.
As such, while checking tigerdirect I found the "Atlona AV Toolbox CDM-660 Standards Converter". It seems to do exactly what I need (fully covering all the potential standards in either direction), and the price is quite reasonable.
Can anyone give me an opinion on this particular unit, or possibly suggestions on an alternative product.
Any and all opinions welcome.
Thanks
Gary

Thanks Burt for the reply and suggestion.
Even with a speedy software solution, it still takes (minimum) 3x realtime (Capture>convert>Burn DVD). Way too much time to be cost effective for my customers! With hardware, it is realtime (Play>burn), and therefore I would not have to charge $100/hr+ for the transfer. I want to keep it under $50/2hr DVD.
The transfers do NOT have to be broadcast quality. It just needs to be good enough for that average joe to get the VHS to DVD and not loose the memories from the tape. Consider, many of these tapes are recorded at EP! Broadcast quality would be a bit overkill...
Thanks,
Gary

Opinion needed on best way to map multiple table joins (of the same table)

Hi all
I have a query of the format:
select A.col1, B.col1,C.col1
FROM
MASTER_TABLE A, ATTRIBUTE_TABLE B, ATTRIBUTE_TABLE C
WHERE
A.key1 = B.key1 (+)
AND
A.key1 = C.key1(+)
AND
B.key2(+) = 100001
AND
C.key2(+) = 100002
As you can see, I am joining the master table to the attribute table MANY times over, (over 30 attributes in my actual query) and I am struggling to find the best way to map this efficiently as the comparison for script vs. mapping is 1:10 in execution time.
I would appreciate the opinion of experienced OWB users as to how they would tackle this in a mapping and to see if they use the same approach as I have done.
Many thanks
Adi

If I run this it takes less than a second in TOAD, when mapped in OWB it takes ages. 10:1 is a conservative estimate. In reality it takes 15-20 minutes. CSI_IEA_VALUES has 30 million rows CSI_ITEM_INSTANCES has 500,000 rows.
Hope that helps. I would love to know how others would tackle this query.

Help - Opinion needed for linked picture - Trackpad Click

I need your help. This was just one of the problems sent in for Depot Repair. It's going back for this and other problems. H.?. at the repair Depot repair said they don't relace stuff that works, hence they won't replace a lop-sided key. Is this right?
It can't be "normal wear and tear" because that just doesn't happen with 4 weeks of use. I bet it will eventually break. That's what I seem to get when reading the forums here.
I contend that af you do a search here for either right click http://forums.toshiba.com/t5/forums/searchpage/tab/message?q=right+click or left click http://forums.toshiba.com/t5/forums/searchpage/tab/message?q=left+click
There seems to be a hint that there are more problems that meets the eye with the trackpad buttons and many of you are reporting problems and suffering. Based on discovering all of the click issues in the Laptop Forums, I believe that Toshiba in Japan needs to address it with a re-design.
Here is a link to the picture: http://i1109.photobucket.com/albums/h427/KeepItSimple2/Toshiba_P1010313640x480LeftClick.jpg The Series in the picture is the A665. A 1 mm thick ruler was laid on top of the key to show the left resting height.
What do you guys think? How do we fight it? Why aren't they listening?
Currently, I have been without a laptop for nearly 6 weeks. What will the extended warranty people have to say.

You can't put a random number generator is a gif. GIFs are images following a particular format (and using compression owned by an evil company which a few years ago anyway were threatening to sue everybody in the world), and is not executable. That doesn't really make sense.
But don't try to describe problem in terms of a possible implementations; that just confuses the matter. It sounds like you want to display images, based on a static gif file, with additional random content added. Is that what you want to do?
I'm pretty sure it's possible to:
(1) load an image from a GIF file, into a buffer
(2) filter that buffer through a routine that draws arbitrary stuff
(3) that arbitrary stuff could include alphanumeric text produced by a random number generator
(4) the output from the filter could then be used to create an image object
(5) that image object could then be displayed.

Opinion needed on MacBook Firewire workaround

I've never really used iMovie and I've got a Firewire camcorder and I want to be able to get the video on to my new MacBook (w/o firewire)
I plan on buying an HD (aka USB) camcorder when new models are released in about a month. But, I need a workaround in the meantime.
I am able to import the video using an old G4 & iMovie 2.0. I figure that I should be able to transfer the imported video from my G4 to my MacBook (Please correct me if I'm wrong on this.)
What I really need to know is if iMovie 2.0 video will import to iMovie '09 and are there any disadvantages to importing via iMovie 2.0?
Thanks for the advice,
Double_A

• It doesn't create an iMovie movie project icon as iMovie 4-6 does BUT a plain folder
• in this there is a folder named Media and in this Your imported material are stored as
QuickTime.mov files
• Copy them to an external Mac OS Extended formatted hard disk (UNIX/DOS/FAT32/Mac OS Exchange
will NOT work)
• as You only have USB/USB2 then it has to be used and when You connect this external HD to Your MacBook
drag the movie material over to the internal hard disk of this.
To work with it on an external USB2 hard disk might work for a while but will
be more and more problematic (stuttering etc.)
This is the way I would try to do it.
I would also see if I could find a more modern version of iMovie that would run on an Old Mac eg iM4

Opinion Needed...exporting iPhoto pics

I already use time machine for my Mac. As a second line of defense for my pics, I was thinking of having a second form of backup. I believe I have a couple options. 1. Use the "export" feature in iPhoto to place the raw files on an external HD. 2. In "finder" drag the iPhoto library over to an external HD. Both seem pretty clean and easy. I have tested both. I am looking for other opinions on the two options. Pros and cons. Thanks.

Back up the whole Library. Why? Because in the event of a problem it's a whole lot less work than starting over from scratch - which is what you will do if you only back up the photos.
Rather than just dragging the Library to the external, use an app that will do incremental back ups. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically. Examples of such apps: Chronosync or DejaVu . But there are many others. Search on MacUpdate
My schedule: My Library lives on my iMac. It’s Backed up to two external hard disks every day. These disks are permanently attached to the iMac. These back ups run automatically. One is done by Time Machine, one is a bootable back up done by SuperDuper
It’s also backed up to a portable hard disk when ever new photos are added. This hard disk lives in my car. For security, this disk is password protected.
I have a second off-site back up at a relative’s house across town. That’s updated every 3 or 4 months.
My Photos are backed up online. There are many options: Flickr, Picasa, SmugMug etc. However, check the terms of your account carefully. While most sites have free uploading, you will often find that these uploads are limited in terms of the file size or the bandwidth you can use per month. For access that allows you to upload full size pics with no restrictions you may need to pay.
Every couple of months I test the back ups to make sure they are working correctly. It’s very easy to mis-configure a back up application, and the only way to protect against that is to do a trial restore.

Opinion Needed on Macbook (college student)

I'm currently the proud owner of an iMac but since I transferred to a university, I've realized the convenience of having a notebook computer. It's portable, I can bring it on campus and work, etc. It's just more convenient to have compared to a desktop. My iMac is a 20 inch from late 2008, with a 2.4 GHz Intel Core 2 Duo, 2 GB RAM, and a 250 GB HDD. I was looking at the Macbook and figured I could probably sell my iMac and get one. I got a buyer who'll give me $800 for the iMac and I can get an open-boxed Macbook at Best Buy from a buddy of mine for about $700-800. I feel so left out sometimes because every Mac owner I know has a Macbook and I'm the only one with a desktop so I feel left out of the Mac culture. I just don't know if it's worth it. I'd go from a 20 inch screen to a 13 inch screen. I do a lot of guitar recording/music editing and DVD burning/creation and some iMovie stuff. So I want to know from you: should I do it? Is it worth it? Any input is appreciated. Thanks.

Hi warheart1188,
What's the specs on that MacBook? One thing to consider, when comparing desktops vs. portables, is convenience. You'll going to pay the additional premium for portable convenience and in many cases will get a less powerful machine (for the same price as a desktop). While the 'gap' has been closed and there are some pretty powerful options in the Apple portable lineup, that $1,999.99 MacBook Pro is the same price as a 27.5" Quad Core iMac!
I personally went the portable route through college and grad school as I was more than willing to sacrifice the extra "umph" for 24/7 portable convenience. Not to mention, most universities will have labs on campus with nice desktops for situations where you need the extra power.

Expert opinion needed: Best practices to handle huge rowsets on UI

Hi All,
I need to know what are the best practices from Oracle to handle huge rowsets on the UI.
My ADF 11g app is a custom monitoring cum reporting tool for a highly active integration solution.
The user can give me a selection criteria say show transactions between yesterday and tomorrow and our highly active transactional system may return upto 5000 records.
I am showing these records in a tabular format and since pagination is not there we are depending on auto scrolling which is kind of slow.
So please advice me what options come to your minds for showing/informing users of such rowsets.
I am aware ideally UI should not have more that a couple hundred records but our use case does not adhere to that.
Thanks

since pagination is not there I'm not sure what you mean by this, the ADF Faces table does pagination when you scroll - so if your business service has 5000 records but the rows property of your table is set to 25 - you'll just fetch 25 records to the client.
When you scroll down you'll fetch another 25.
This type of thing is automated for ADF BC data controls - and you can control the range set.
We also generate the code needed for EJB Facades to do this with JPAs.
If you have your own Java class as a data source you'll need to implement this pagination on the business service side see exapmle 37 here: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html

Query Exception Expert Opinion Needed

HI
WE have this particular case we are yet to find a problem on, your assistance with this would be awesome.
SO the problem is as follows:
- we have two Key figure (K1 & K2)
- Many conditions based on the two key figures should be shows in different colours
Ex:
Green - k1 (85 % or Greater) and K2 (Between -5% and +5%)
Blue - K1 (80% or Greater) and K2 (Between -8% and +8%)
White - K1 (75% or Greater) and K2 (Between -10% and +10%)
Red - Everything else in Red.
Thanks you for your help with this....
D

Hi Darshak,
Green - k1 (85 % or Greater) and K2 (Between -5% and +5%)
Blue - K1 (80% or Greater) and K2 (Between -8% and +8%)
White - K1 (75% or Greater) and K2 (Between -10% and +10%)
Red - Everything else in Red.
To achieve this you need to create exceptions in the query designer.
Create a exception as named "Green K1"
Green >select Good 1 in alert level>operator ">">Values "85%">click transfer
and create one more "Green K2"
select Good 1 in alert level>operator "between">Values "-5% and +5%"-->Click transfer
Like this do to other colors also ... but you cannot achieve the BLUE, WHITE colors.
You have only 3 colors, Green, Yellow, Red.
If you want other than this then you need to work on the Excel Macros... Which is lengthy and trouble some process.

Your opinion needed - generating unique ID from a URL

I am currently making a web crawler type program and before rushing straight in and coding something I thought i'd gather a few "expert" opinions so to speak ;)
A crawler obviously takes a URL, downloads it and saves it in a database somewhere. However I need to keep a record of which URLs have been previously crawled - as not to crawl and recrawl the same URL.
Ideally I need to make an algorithm which takes a String URL and outputs a unique ID for that URL - no other URL would be assigned the same ID.
After a while researching I have ran into base64 which could take a URL and output a long String of characters. I have a question here though:
1. Is base64 always going to output UNIQUE IDs for every URL or is there a slight offchance you could have duplicates?
However even if base64 worked and it gave me the ID:
aHR0cDovL3d3dy5qYXZhLmNvbQ==
For the URL:
http://www.java.com
I still have to record it in a database and search for its prescence to determine if the URL has been crawled before.
So my question is:
Is there a way to construct a unique NUMERICAL ID for a URL?
This way, it would be much easier to find the record if all were sorted by their numerical ID number.
Hope I havent confused you, if I have just tell me!
Thanks
-Myles

I need a numerical representation of a URL as it would reduce the time to search for a URl to check if it had been previously crawled.BUNKUM! Sorry, but it is... you're talking about saving pooftenths of second on each database seek... but if you're web-crawler isn't inherently I/O bound (say what 2 to 5 seconds a page) then who's your ISP? and how much do they charge.
IE: Your barking up the wrong tree. Just use an MD5's, keep your "current site" in a hashset... for instance if was crawling http://forum.java.sun.com I'd load a hashset from the DB of that domain... crawl within it, and save the whole shebang back to the DB in one hit, delaying any external links until the end.. then load each of those "sites" and crawl and save them, again delaying any external links... and so on until the end of time in all probability.
And, sorry, you're reinventing the square wheel again... ever heard of jackrabbit?

Question on buying MBP - opinion needed

I currently own a last generation PB (1.67G with 2G RAM) and was thinking if it would worth the $ to upgrade to MBP.
Since my PB is almost running out of capacity (only 15GB left, and it will get used up pretty quick)...also I have a feeling that web browsing performance will no where near a MBP even already I maxed out the RAM.
But, I also heard Leopard 10.5 will be released in October.
Here're some of my Qs:
1. shall I wait until that time and buy one with the 10.5 or get one now and upgrade it later?
2. what's the difference between 2.33 and 2.4GHz besides the processor speed?
3. if you own both PB 1.67 and a MBP (i.e. one w/2.33 or 2.4), do you see a huge difference in speed on web browsing?
4. is there a software out there that works like carbon copy cloner for intel Mac's?
5. last question, is there any way to boot a PPC-cloned OS 10.4 Tiger from MBP? For example, I cloned my PB's OS 10.4 Tiger to a bootable external firewire drive. Is it possible to boot up that drive from a MBP? If not, any solution?
thanks

1. Depends, if you can get by with what you have, then you'll save $129 bucks by waiting.
2. Major difference is the 800 mhz FSB vs 667 mhz fsb, the santa rosa chipset (allows expansion to 4GB of memory) and the graphics chip, Nvidia 6800M GT vs. ati 1600.
On the 15" the backlight is led, on the 17" you get the option of a hi res screen.
3. For universal applications, the MBP will blow away the PB. It has 2 cores giving it 2 processors. As far as web browsing, you probably will see a minor increase in response, but most of the performance of a web browser is limited by internet connection speed, not the computer.
4. Carbon copy clone works for the intel macs.
5. No, the PPC clone doesn't have the needed intel code. But you can use migration assistant to move all of your programs and data files over. It works very good. Also, the new MBP has some OS files that are needed from the original install. I tried to clone a 10.4.10 copy from a Macbook and it failed miserably on the MBP even though the system was 10.4.9 on the MBP.

Dynamic rendering of FXG - expert opinion needed!

Hi,
I need to build a Flash application that can dynamically load
and display FXG files from a remote database.
In Silverlight this would be straightfoward (you would load
XAML) but it is not clear whether this is going to be possible with
Flash at all. The solutions might be:
1. Flash Player natively supports dynamic loading of FXG, and
addition of described graphics to a canvas or similar object
2. Someone writes ActionScript to parse FXG inside the Flash
player and add the graphics to a canvas or similar object.
Does anyone have any ideas about what is possible with Flex
4, or what might be possible in the future?
Desperate to nail the answer on this one!
Best, Dominic

Hi,
i am also looking for this.
Hopefully, Flash player supports the format natively in the future like as easy as loading a jpg
But meanwhile i am sure it will be relativly simple to implement a renderer/parser for FXG with AS3 (willing to start that soon)
It will be a god send for CMS applications for Flash websites. (Having FXG editor and renderer)
I am %100 sure it will be possible to do this since FXG format is based on Flash player rendering capabilities
Cheers,
Ali Tan Ucer

Tecra M4 or Portege M400: Opinion needed

Hi
I'm planning to buy a tabletPC and for almost 100% have chosen Toshiba. The prices seem to be ok. But I still don't know what to choose - Portege M400 or Tecra M4.
The M400 is newer, lighter, longer battery operation and I can have a Core Duo cpu. However I use programs like Photoshop, AutoCad, 3ds max, Corel and so on.
Is the Intel's chip enough for these purposes? The M4 has the GF Go6600 GPU which I'm sure is ok.
Please help! Thanks for advice!

Hi
I have investigated a little bit in the internet and found some data about the Tecra M4 and Portege M400.
It seems that Tecra was delivered with different hardware configuration.
You can buy the Tecra with Intel-Pentium-M (Dothan) CPU 760, 750, 740, 730 1.6GHz,1.73GHz,1.86GHz, 2.0GHz and 2 different graphic cards: 64MB nVIDIA GeForce FX Go6200 or with 128MB nVIDIA Go6600.
Also there are different HDD sizes; 40, 60 and 80GB
The display screen is 14.1" (1400x1050).
The same on the Portg M400. It was also configured with different CPUs:
Intel Core 2 Duo (Merom) CPU T7400, T7200, T5600, T5500.
The graphic card is a little bit slower because its a sheared memory graphic card.
But you know, if you are not a hardcore game player so you dont need a high performance graphic card. The display size is a little bit smaller. Its 12.1
I think if you like small notebook so the M400 is not a bad choice.
But you know its your choice and you should know what you want to buy.
But I like more the Portege unit
