Hi Ahmad,

In your experience, when developing a new application, are you better off starting with an OO domain model or with a database ER-model?

In fact, here's the spec of a system that I looks like it might be ok. It comes to about £1000 (GBP) which is about $1600 (USD).

Hi,

I was planning to build or perhaps buy from a bespoke manufacturer. I tend to avoid the big names like Dell to be honest. Core i7 seems like a good choice - I was thinking of the i920 with DDR3 memory and a RAID 0 (mirror) disk configuration.

Can you give me a recommendation on graphics cards? I don't really play games so don't need much in the way of 3D power. Overall, I'd like the PC to be quiet so I think a less powerful graphics card would be a good choice.

A final, perhaps nooby, question about Windows 7 64-bit. Can it run 32-bit apps too or do you have to find the 64 bit versions?

Thanks,

Sid

Hi All,

It's been a while since I bought a PC, so I'm a bit out of date and would appreciate some help. I'd like a workstation PC for doing development and perhaps some video & photoshop too. I was thinking about a Core i7 but am not sure whether that is much better than a Core 2 Quad. My budget is about $1500 including OS but excluding monitor.

I have a few questions that you may be able to help me with:

- Core i7 or Core 2 Quad - which would you choose?
- I plan to install 6Gb of RAM so will probably go for the 64bit version of Windows 7. Are there any gotchas that I should know about?
- With respect to monitors, what is the difference between a TN panel and an IPS panel?
- Any recommendations on motherboards and hard-drives?
- Are there any websites that give standard recommended specs for fast PCs?

Thanks for reading.

Hi,

If I have two LDAP servers running in Master-Master mode, can WLS failover if one of the LDAP servers goes down? That is, can I specify both IP addresses in WLS along with some kind of timeout. I looked in the console, but couldn't see where I might type in two IP addresses.

I guess the alternative way to do this is at the infrastructure level using a virtual IP address.

Thanks.

Which database are you using? Oracle 10g has a SOUNDEX function for phonetic string-based search.

Take a few days off and don't touch the books. Then go and do a couple of mock exams to see how you do.
Weighting? I'm not sure that I've ever heard anyone mention that there is a weighting applied. You can be sure that there will be at least one question on each section though.
There is a SCWCD 1.4 voucher for sale on eBay :-

Voucher for Sun Microsystems SCWCD (310-081) Exam (#270067613289)

Unfortunately, it expires soon (31Dec) - could be good for someone doing a retake, or someone who is ready now.

Go to the Prometric Web Site. There you can search on a per country basis for examination centres for the SCWCD exam.

It's a poorly worded question since all objects will satisfy "IS-A Object". Therefore, you could argue that (1) is OK since Bar implicitly extends Object and (3) is OK since the base class Bar again implicitly extends Object.

There's no such thing as guaranteed behaviour when it comes to the scheduler. When you call yield(), the scheduler may allow another thread to run whether higher or lower priority or may immediately run your thread again.
> My basic doubt is how will the sender know the recipient's public key?

Normally, public keys are distributed in X.509 certificates. A certificate binds a public key to an identity and allows you to confirm that the key has not been tampered with.

Personally, I would put the certificates into an LDAP server which means they would be accessible to all your processing engines. LDAP servers are designed for this kind of thing.

> So I should use only OpenSSL to do all these programmatically or can I still use keytool?

The article talks about how to create a PKCS#12 keystore that contains client keys and certificates. Sun's keytool works with a JKS keystore by default, but can read (not write) PKCS#12 files as well. You can also read both keystores programmatically.

Oops...my bad. The very latest version of Axis1 does support Java 5. I guess that it won't be around for too much longer though as Axis2 seems to be the current favourite.

Thanks for the heads-up.

Here, RMH says that "Everyone knows that SOAP Encoding is a bad idea anyway".

Anyone care to explain why that is???
