Is Flatfile any better than SQL ?

Hey,
I've heard that flatfile databases have a better response than SQL ones.
However, I know SQL is much more easy to change and modify.
So, is there a good reason to go with flatfile, or just go with SQL, since computers are fast enough nowadays ?
thanks,
Dennis

well it depends on what u want to do.....RDBMS's have been developed after millions of dollars worth research and time...they have sophisticated indexing and algorithms to improve performance,security and easy backup and recovery
flat files are of course easier to learn,but the drawback is u have to write the algorithm/logic for searching,sorting etc..i have heard from some places that some websites use such a mechanism for ex smyle and prevlayer that make use of object persisitence and store data in flat files...but most of the time these will be simple applications with few updates and a lot of lookups
ultimately it comes down to cost and area of usage...big complex applications are better off using RDBMS while flat files are better where the application is simple and less complex...
hope this helps,

SQL Program better than SQL*Plus

Hello
Do you know any program better than SQL*Plus for Oracle Database?
I also know TOAD and SQL Navigator, is there any other
If yes where can I download it ?
Thanks in advance.

Hi Kurt.
RoboSource Control to my knowledge hasn't been developed in recent releases. It is essentially the same product that existed years ago. It works, but does not have a lot of users. Most people, including myself, prefer to use third party products such as Perforce, SVN.
As RoboSource Control is an old product and isn't widely used, I doubt whether anyone has tried using it on SQL Server Express 2012. That is not to say it won't work on it though.

Is short any better than int on cheap mobile phones?

Hello,
I'm writing an open source 6502 emulator (http://jbit.sourceforge.net/). I've written the CPU code very quickly to focus on the rest of the system. Sooner or later I will refactor the CPU code and in the process I will speed it up a bit.
The point I'm not so sure is this:
class VM {
byte[] memory;
short get(int address) {
return (short)(memory[address] & 0XFF);
class CPU {
VM vm;
short accumulator;
void step() {
accumulator = (short)((accumulator + vm.get(address)) & 0xFF);
}The code is simplified but the relevant information should be here. As a side note; replacing VM.get with direct access to memory is out of the question (the real get is more complex than that).
6502 is a 8bit CPU, The intuitive solution would be to use byte for accumulator/VM.get and that was my first version (before releasing). But some code was a pain to get right (I've found working with signed bytes very inconvenient) and in the test phase I decided to look for a easier solution to quickly get a working CPU. If I was developing for J2SE I would have gone for ints, but since I don't know CLDC very well I looked for other emulators and I found one that used short. It seemed a reasonable compromise; not as convenient as int, but perhaps faster on cheap phones (16bit CPU?). But now that I'm planning a refactoring I'm checking this assumption. Of course, I would rather work with ints than with shorts (let alone bytes).
Has anyone some insight about whether shorts are actually faster than int on most real low-end devices (e.g. CLDC 1.0, 2-3 years old, 50-100 USD/Euros at the time of release)? By how much? Or byte is so much faster to be worth the pain?
Also note that VM.get is part of a public interface (see http://jbit.sourceforge.net/doc/hello.html); I can change it, but I need some solid reasons to do so.
Thanks,
Emanuele

Just to let you know.
I've looked into the generated bytecode and I've reviewed the JVM specification. My impression is that short is pretty much useless, unless you want to save space in fields.
The J2ME VM uses basically the same class format as the J2SE VM and thus has very limited support for shorts (and bytes). Even assuming that a mobile phone is using a 16-bit CPU, I doubt that the JVM implementation would be smart enough to figure out when 16-bit operations could be used.
Of course, if you know any better I would appreciate your comments...

Apple TV - any better than an ipod?

Before I went and got an apple tv I decided to hook up my ipod video to the tv and see what the quality was like. So I ran svideo from a dock into my 32" sony lcd. It actually looked rather good for standard def programs (ie all itunes material). The Daily Show looked just fine and even The Office and The Riches playing letterboxed widescreen looked fine even when I zoomed the letterbox full screen with the tv.
I'm sticking with the ipod for now. Wondering if someone with the apple tv would like to try a comparison.

Wondering if someone with the apple tv would like to try a comparison.I find that the same file played from TV looks visibly better than when played directly from the iPod. HDTV scalers vary so results may vary with the quality of your particular HDTV/EDTV model. However, it would seem the TV is specifically enhanced for playback of such files and, in general, does a better than average job of scaling here.

K8N Neo2 Platinum overclocking - get any better than this?

I know only slightly more than nothing about overclocking, especially when it comes to dividers (what's a divider?) and so far I've managed this stable overclock on the specified CPU (using stock AMD cooling):
But I can't get the memory clock to 400MHz dual channel (yep, I'm using different brands):
Is there any way I can get better overclocking out of this kit? I've been upping the FSB in steps of 5 and 240 eludes me (freeze at Windows boot, but I may be able to creep closer in steps of 1). I haven't tried to improve AGP yet - it's still at 66MHz in the BIOS - but any feedback with regards the CPU, RAM (and timings) and everything else will be greatly appreciated. Thanks.

First off all, you're mixing ram. That's a bad thing to do even for a stock system, let alone overclocking. As you can see from the SPD tab, both memory sticks have completely diffirent timings. My advice is to get a matched pair of ram - 2 identical sticks. You need a memory upgrade anyway, 512Mb is not enough these days and slow you down so much the oc becomes pointless imo.
You can try to enter the slowest timings (3-6-6-11) manually in bios. As you can see from the memory tab, the actual timings used are way tighter then the SPD timings of the OCZ dimm. Altough the OCZ SPD timings are for 263Mhz the used timings might still be too tight for it.
There are 2x512Mb Corsair + 2x512Mb OCR in there that, unfortunately, won't be getting changed anytime soon. :-(
Quote from: Exo on 17-June-07, 22:35:54
You might also be hitting the max of your cpu - Lower the CPU multiplier and check if you can clock the bus higher.
Upping the bus is easy enough, but where in the vanilla BIOS is the option to decrease the multiplier?

I'm still using Snow Leopard because heard too many horror stories about upgrading to Lion. But I can't upgrade Safari unless I upgrade OS. Is Mavericks any better than Lion?

I'm still using Snow Leopard OS because I heard too many horror stories about people upgrading their OS to Lion. But I can't upgrade Safari anymore unless I upgrade the OS. I get messages constantly telling me I need to upgrade my web browser, and have increasing problems correctly viewing pages (like L.A. TImes, NY TImes) because Safari needs upgrading.
I can't really tell what the advantages are to upgrade to OS Mavericks or OS Yosemite because it seems most are intended for mobile apps, and I only use my desktop.
My last upgrade to SNow Leopard wiped out 2/3 of my iPhoto collection. No idea why and no fix. Macs used to be the epitome of compatibility for upgrades — not anymore.
What are my options? What issues would I encounter if I upgrade OS to Mavericks or to Yosemite? WHat are likely problems, advantages and disadvantages?
Thanks for any help sent my way.

If you do want to upgrade.
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
Application Compatibility
Applications Compatibility (2)
Do a backup before installing.
One option is to create a new partition (~30- 50 GB), install Mavericks, and ‘test drive’ it. If you like/don’t like it it, you can then remove the partition. Do a backup before you do anything. By doing this, if you don’t like it you won't have to go though the revert process.

Does CS4 render styles any better than CS3?

All layouts I'm now doing rely on CSS layers. That's what the
Layout Police now require. But DW CS3 doesn't do a good job of
rendering the complex CSS in Design view (they look fine in the
browsers), so I've gone back to the future, coding my pages in
Source view like I'm using HomeSite and it's 1998. And I thought
Groundhog Day was over.
Has anyone here been using CS4 for complicated layer-based
layouts? I'm wondering if it does a better job of displaying the
pages.

It's not. Frontpage and GoLive have always used the term
(initially coined
by Netscape) as well.
> used the term layer as a div that covers another
"Layer" has always meaned a container that is absolutely
positioned. Since
this is often a <div>, it has been colloquially
'blurred' to refer
specifically to <div> tags, but that's really improper.
This is why DW has
moved away from the use of the term altogether, and now calls
them
'absolutely positioned elements'.

But do you understand CSS positioning, and its ramifications?

cool.
You should. It is.

Will Final Cut Express be any better than iMovie for colour resolution

Hi
I have just made the move from a Laptop/Windows to a Macbook Pro, whilst running on the Laptop i used Ulead Video Studio V10.5 to capture and edit DV movies from my Panasonic NV-GS180. Once I learnt the basic the output results were very good, eg. an mpeg movie file of around 2.5GB for an hour of video.
Since moving to the Mac I have uploaded 2 recent DV tapes into the standard iMovie application. I have done a simple upload with minimal editing just to prove the quality of the output. I have output into H.264 format and the resultant file is around 2.5GB for an hour. The quality of the video is very poor compared to the equivalent on the VS10.5. Now, so by "poor quality" i mean the colour resolution is literally rubbish, on VS10.5 there are many different shades of the same colour, whereas in iMovie there is literally two. The resolution also looks worse, but I have read that iMovie doesn't handle the original interlaced video from my camcorder. So, I am more than willing to but Final Cut Express if my two problems with iMovie are addressed to achieve the same quality as VS10.5 on my old windows XP Laptop. There's no Trial like there is with Aperture, which I have recently bought to improve on the original installed iPhoto.
Any help, advice or comments gratefully received.

hi Ian
In store, we were using an huge Mac, whereas I am using a Macbook Pro. I must admit I did not try iMovie in the store to check the quality was equally as bad. But I can confirm that since installing FCE4 on my Macbook Pro at home and capturing the same piece of video that the colour resolution is the same as in store, so all is good.
Cheers

Is Leopard any better than Tiger?

Hi.
I have a Macbook bought in 2007 running Tiger. I also have a Leopard software upgrade bought from Apple when it came out. For various reasons I never installed it and have run Tiger with no problems. In the next week I am going to upgrade to 2gb RAM and a 320Gb 7200rpm Hard drive. I was going to install Leopard after cloning the original HD to my new one.
However....
I have read various worrying threads about Macbook owners having wi-fi connectivity problems after upgrading to Leopard. Some even had the problem with later versions of Tiger - see below.
http://discussions.apple.com/thread.jspa?threadID=1231631&start=0&tstart=0
It appears Apple have not come up with a definitive solution to these wi-fi problems, even now, 18 months after they were first reported.
Is Leopard worth moving to if I have had no issues with Tiger. I _*DO NOT*_ want any new problems especially regarding internet connectivity.
Anyone had similar experience and would like to share/advise.
Thanks
Del

Hi GDF
Thanks for more of your advice. I've also posted this on another discussion and the replies have all been positive like your own.
It would seem that many problems with wi-fi connectivity appear to have been with the hardware initially but may have been made more noticeable by the installation of Leopard. After searching through various threads it appears that these wi-fi problems are still about. I would hate to make what has been a really good user friendly system (Tiger) anything less.
As you say I would have a clone to put back in should I have any issues after installation.
I'm hoping to do this next week once I get back onshore. I'll keep you posted on the whole operation.
Cheers

Is rural reception for iphone6 any better than previous iphone?

Debating whether to try iphone6. I get very weak reception in a rural area with no power. Haven't had good coverage since the antennae went internal. Any thoughts?

I have the same question I live in the out back of New Mexico.

Is current iphone4 bumper any better than original?

I just got a new iphone 4 and wanted to buy a bumper. I have the original bumper thru the free case program, but its getting a bit warn.
Has any improvements been made in the past year, has quality improved, or are they any issues anyone experienced with scratching on the metal band?
I just don't want to mess up this beautiful new and shinny gem!
Thanks bunches

I believe so. The dock connector and mute switch have larger holes for easier access. Go visit your Apple Store to see if you can get a replacement.

Is Flex 4 Training from the source any better than Adobe's own Using Flex 4?

I am preparing for the Flex 4 ACE exam from Using Flex 4. Is there a good reason for me to switch to the training from the source book?

Firstly note that F4TFS is in 2 parts, and although part 2 appears to have been published at the end of 2010, AFAIK it appears to be unavailable right now. I have read F3TFS, and am going through F4TFS at the moment. Using Flex 4, available free as a 32Mb PDF, is a very useful reference, along with the 12 or so other Flex books available free from Adobe. While Using Flex 4 is a reference (including plenty of example code), F3/4TFS is structured as a series of lessons, working on the same project (Flex Grocer shopping cart app) throughout. It touches on most aspects of Flex development, and is a great guide for beginners. If I have one criticism of the book, it is that a shopping cart example is going to be inherently dull- so if you have a low boredom threshold you will have to force yourself through the examples. I would still recommend it as a beginner's book, although in the real world you are unlikely to be using Design Mode much, except for throw-away prototypes. If you have a project you want to get started on right away, then you could just wade in and start coding using the Adobe documentation for help, but if you'd like to have an existing example, then F4TFS is for you.
When learning Flex its best to read as much as possible, so I'd widen your reading if possible to include the Flex 4 Bible, AdvancED Flex 4, Enterprise Development with Flex, etc, and the absolute shedloads of blog posts and examples on the internet.

OCS 10g any better than 9.0.4.1 or 9.0.4.2?

Hi,
Our organization had 2 very poor implementation / pilot experiences with OCS 9.0.4.x -- once each with 9.0.4.1 and 9.0.4.2 (extremely slow mail delivery to distribution lists, broken portal links with SSL app tier, etc. to the tune of 40+ other TARs). Both occasions we yanked the implementation (albeit the first time involuntarily). We are looking at OCS 10g and are wondering whether the problem with slow mail delivery is still there?
One forum thread of "New With Collaborative Suites" by jbotta goes into great detail of others experiencing slow mail delivery but the OCS version isn't given.
Also, the State of Wisconsin dropping their OCS contract article http://www.madison.com/archives/read.php?ref=wsj:2006:02:25:545530:FRONT doesn't provide the OCS version. I would like to get concrete input please on whether there truly has been drastic improvement over the 9.0.4.x product.
Thank you in advance,
James

N97 Mini any better than N97?

I've been offered a N97 Mini as a replacement of my design flawed N97. Nokia has not been able to address my issues in due time. I've had all the usual stuff; software issues (hangs, reboots, out of memory), no lock or bad reception on GPS and severe halos on camera. The camera is still a mess after Nokia applied "the scratch fix" and is unusable when the flash has been used.
I know the N97 Mini has less memory, no FM-transimtter, etc. But is the N97 Mini free of the N97 issues or should try to get a refund in money instead?
Helsinki, N97 White gone to recycling, now trying N97Mini...
Solved!
Go to Solution.

The mini tends to have less issues as phone memory C is larger so doesn't run out of memory as quick and freeze, if you want an expert opinion look here

New MBP's better than the old MBP's?

i have a 2009 13" MBP and been none too impressed with it. i just had an issue with wake from shutdown and i am wondering if the new MBP's are any better than the old ones.
i have been told i have issues because i am a "power" user (even though i don't really feel like i am and i don't do anything computationally intensive on the laptop) and i'm wondering if i have to get the 15" to get full power, if there is a machine anyone would recommend etc.
i have been sort of hankering for the 12" that is rumored to come out in part for the form factor and portability but i am a bit scared that this will be a step down and mean i have additional problems.
thanks for any advice.

I also agree that the 12" not only has the best keyboard but is the best Mac ever, and I am not looking forward to the day that I have to put the ol' girl down.
I still mourn mine. One tiny solder connection on the motherboard broke, and it is $800 to replace, but I sure loved that computer. Bought it the week it was introduced and it was wonderful.
