Basic questions about connection sharing and radio mode

I just got TC and have a couple of basic questions.
At home I have a D-Link ADSL modem/router (no wifi) plugged into the wall, and would like TC to provide wifi. I've connected the WAN port to some LAN port of the router and everything works fine. The intented usage of the setup is wifi-only. Would you recommend TC to do DHCP/NAT? Or is Bridge mode better? In the latter case I don't fully understand who's routing the wifi network (though it actually works).
Second question is about radio mode. My wife has an iBook G4 that is not capable of talking 801.11n, so I selected the n mode compatible with b/g. In that mode my black MacBook will still be able to talk 801.11n with TC? The iBook has very low usage, it is fine that computer uses 801.11g for TC, but I'd like the MacBook to go full-speed. (If that's not possible I'd ponder purchasing an 801.11n adaptor of some sort for the iBook.)

Would you recommend TC to do DHCP/NAT? Or is Bridge mode better?
It doesn't matter.
In the latter case I don't fully understand who's routing the wifi network (though it actually works).
The D-Link modem/router.
In that mode my black MacBook will still be able to talk 801.11n with TC?
Yes. It will only suffer lower bandwidth if the iBook G4 is actively connected.

Basic questions about Bigdata, NOSQL and Hadoop

Hi,
I've basic questions related to Bigdata. (I've googled it but still wants to confirm with experts)
Please correct me if I am wrong on below.
1) As far as I know big data is collection of unstructured data. Even we can store relational data as well.
2) NOSQL is an Oracle product to handle bigdata (un structured data and relational data as well)
3) Hadoop is the only one frame work which is avilable in market to manage the bigdata.
What are the other database systems we have in the market to manage the bigdata.
Cheers,
Suri

Hi Suri,
1) "Big Data" does not have a crystal clear, black and white definition.
It is generally characterized as being the processing and management of an amount and type of data that makes a specific workload on that data slow and/or expensive.
Most commonly, Big Data involves processing and management of unstructured data of large volume and the typical technology used to store/process it is Hadoop, However, on occasion a NoSQL database will also deal with unstructured data.
Big Data is also seen often in the form of simple, semi-structured data of both large volume and/or large velocity and the typical technology used to store/process it is a NoSQL database. However, on occasion Hadoop will also deal with semi-structured data of large volume.
In some cases, Big Data is seen in the form of highly connected data that will be manipulated by advanced algorithms that will need to touch a lot of the data and the typical technology used to store/process it is a Graph type of NoSQL database.
2) NoSQL is a category of database technologies most often dealing with the issues as outlined in bullet 2 above. The Oracle NoSQL Database is oracle's product in the NoSQL category of database technologies. It does NOT store relational data. When using NoSQL relations between the data must be managed within the application code.
3) Hadoop and NoSQL booth manage Big Data, but different aspects as discussed in (1) above. Hadoop is a batch based, slow processing data technology, but the "slow" is relative because it can process very large amounts of data, so minutes is commonly seen as fast. NoSQL is a near real-time data processing technology and typically deals with Big Data where access times are in the single digit millisecond range.
Hope this helps,

Some basic questions about foriegn key , and relationships.

Hi
Thank you for reading my post
I read some documents about foreugn key and tables relation ships.
but i still can not understnad some stuff.
1-when we have a foreign key , we have two tables that we want to relate them together
in a way that one of ? table columns forced to be a value from ?? table column.
what is name of those two tables , i saw , child-parent , ..... which confuse me.
can some one please tell me correct name of those two tables ?
2-some times we need some kind of master details relation like :
one-to-many : i this case MANY table will have a column to point a record in ONE table , can this relation be a foreign key relation ?
3-we can achieve many-to-many relation only by using a helper table to host both tables primary keys in a record to relate them together.
can you point me to some resources that help me to find answers to this questions ?
or explain them to me ?
thank you for your time.

These are critical database basics that you need to understand. I would seriously recommend getting some study in, because proper relational database design relies on the basic principle of data and relationships and a process called normalization.
In reality, you only really need one gigantic table to host data. It would include everything you would want to know about something - let's take a sales order for example. You would have to record the customer's name, address, etc. along with every item they ordered, etc. You would have a HUGE table full of data that appeared over and over and over again. This is bad design for two basic reasons: it is difficult to query, and it is very easy to have minor mistakes like capitalization or alternate spellings that prevent things from matching up properly. For example, let's say Bob orders 40 widgets and 40 digits. In our hypothetical table, we could put it in as Bob - 40 widgets and Robert - 40 digits. See how confusing this can get even in a simple example? And let's say you wanted to correct all of Robert's orders to say Bob and you found out there were 40 orders from "Robert" How would you know which ones to change?
The process of normalization helps to reduce the chance for these types of errors in addition to creating a good basis for indexes. You normalize the data by creating sets of parent/child tables with a "key" value to match them. In our hypothetical situation, you could create a table for orders and a table for customers. In the customers table you give all the detail for the customer in one place, and you assign each customer a unique number or ID. In the orders table we add the customer ID (NOT the name) and we ensure that we are getting the customer we want, in addition to saving a lot of space and eliminating redundancy. In our example, the customers table is the "parent" table and the orders table is the "child" table. The child table references the unique entries in the parent table via that id. That reference is referred to as a foreign key. The foreign key in the child table points back to the original and complete record in the parent table and eliminates the redundancy of keeping all that extra data for every order. Foreign keys in child tables always refer to a primary/unique key in the parent field.
That help?

A few questions about internet sharing and security

Hi, I have an iMac connected to my aparment complexes' wireless network. I realize this isn't the safest way to be online so I was wondering what I could do to protect my computer. When I open a finder window I see all the other computers listed in the "shared computers" menu and this makes me nervous that mine is showing up in others' finders as well. I would like to know how I can prevent everyone else from seeing my computer on our shared network, and possibly prohibit those that still can see my computer from getting access to it. Sounds a little perinoid I know, but it just bothers me to know people have potential access to my files and such. Also I have an Apple tv and wireless printer. I was wondering if there was a way to connect my own wireless router to my iMac (via the ethernet port) directly so that I would have an exclusive (to me and possibly my roomates) connection to wirelessly print, transfer media to/from the Appletv, and rent and buy things from the Appletv online, but also stay connected to the internet. I hope that wasn't confusing, but would appreciate any ideas.

jbloc,
Well, the main problem for you is that you are on what is essentially a "public" network. As far as your Mac is concerned, however, all you need to do is turn your Firewall on and not run any services. It is only when you might run some service that your computer would show up in someone else's Finder (if it is another Mac), or in the "Network" window (in Windows).
Even when you do have services running, other users must have the proper credentials in order to gain access to those services.
Really, the only way to completely protect yourself and firewall your entire network would be to subscribe to some broadband service on your own, and have your router connected to whatever modem is supplied. The router would then be protecting your entire network, and only your devices would be connected. You would be the only one to see and potentially access those devices. Otherwise, you just have everything left out on a public network, and you would be dependent solely on the security you are able to set up.

[JS] Basic question about event listeners and event handlers

I am very new to the whole topic of event listeners and event handlers. I'd run the test for the following problem myself, but I don't know where to start, and I just want to know if it's impossible -- that is, if I'm misunderstanding what event listeners and event handlers do.
Say I have an InDesign document with a text frame that is linked to an InCopy story. Can I use an "afterImport" event listener on the text frame to perform some action any time the link to the InCopy story gets updated? And will the event handler have access to both the story that is imported, and the pathname of the InCopy file?
Thanks.

Thank you, Kasyan.
Both of those are good solutions.
We are currently using InDesign CS4 and InCopy CS5. I'm hoping to get them to purchase the whole CS5 suite soon, since I'd like to start writing scripts for InDesign CS5 as soon as possible, as long as I'm going to have to be doing it in the not too distant future anyway. The greater variety of event handlers sounds like it might be something that is crucial to the project I'm working on, so that adds to the argument for getting CS5.
Thanks again. You have no idea how helpful this is. I made some promises to my boss yesterday that I later realized were based on assumptions of mine about the InDesign/InCopy system that didn't make any sense, and I was going to have to retract my promises. But after reading your response I think I can still deliver, in a slightly different way that I had been thinking before.

Basic questions about word spacing and vertical alignment with CSS

I'm sill very new to Dreamweaver and web page designing. I've
read the entire manual SC3, one book, and starting another but I
have almost 0 practice.
Q1. so far I haven't been able to produce the effect of the
Word Spacing property. I tried all kinds of tests and I don't know
in what scenario this effect will show. Can someone give me a
simple example that shows the effect of this CSS property.
Q2. Vertical Alignment: this works well with images inserted
into text but I also expected this to work with text against other
text. For example I typed TEST© and assigned a different SCC
style to the © so that I can make it smaller and put it up
with the Vertical Alignment property. Surprisingly this propery
didn't produce any effect. How is htis suppose to be done?

> This is some text. This is some text.
You forgot to wrap your text in <p> tags so the style
rule you created
doesn't apply.

Basic questions about downloading updates and smartnet licensing

I have been trying to get a definitive answer to these questions by browsing around cisco.com, but so far no luck.
1. I manage an ASA5510 for which there is no current smartnet contract. It is running an outdated code version (8.2) of the Security Plus license. Is it allowable to download the 8.4 image and upgrade the ASA as long as I stay within the Security Plus license, or would there be a fee?
2. Same question in general for routers without smartnet: If I have a router running old v12.x code is is permissible to upgrade to 15.x code as long as the featureset remains the same?
3. If I were to purchase a new ASA feature license (e.g. SSL VPN 50 users) and then install it on this ASA, would the license be recoverable if the ASA were to become unusable because of a hardware failure?
Help on any of these questions would be greatly appreciated. All doc I have found so far either seems either contradictory or ambiguous.
Thanks,
-Mathew

Answer 1:
If you do not have a SMARTnet agreement for the device that you support, you will be unable to download updates for that device. You will need to have a CCO login with an active SMARTnet agreement for that device.
Answer 2:
Same answer to question 1 applies to routers. You will be unable to download updates if that device does not have an active SMARTnet agreement.
Answer 3:
If you add a feature, like updating the user license, you will be unable to transfer it to a new unit. This is because the license is bound to the device serial number. The new device will have a different serial number.
Just to mention also, If you add a feature and have an active agreement, you will need to purchase a new agreement to cover that feature. The original agreement only covers the original device. If it goes bad and needs replacing, you will receive a replacement like the original. It will not contain the added license and you will be unable to install the license on the replacement unit because the license is bound to the serial number. The replacement will have a different serial number.

Very basic questions about JSP server and plug-in.

Hi all,
I am wondering what are other ways to make use of the JSP script on a server running normal Apache without changing it to Tomcat. Is there a plug-in version of JSP for Apache that will enable JSP? I am looking for something like PHP plug-in, which is quite generic. They even have a php.exe that OHTTP (a great shareware Win32 web server) can call to run PHP. Is there such thing along this line with JSP on Win32 or Linux? Thanks!

You need a jsp/servlet engine, and in effect, Tomcat is the "plug-in" you described. Tomcat has basic web server functionality built in, so it can run stand-alone, but it's most commonly used with a robust web server like Apache. You don't have to "change it" to Tomcat - you just configure Apache to forward specific urls (anything ending in *.jsp, for example) to Tomcat.

Basic Questions about JSF, Login and Session

Hi,
I try to implement a login/logout function on my jsf-website. I create one <form> with Login and Pass to enter. My AuthenticBean(sessionbean) checks login and pass. If Login is "ok" the login and pass will set in the authenticBean (min. value of login and pass = 2).
Now I check protected .jsf files (files who need a login) if in the AuthenticBean the login.equals("") or pass.equals(""). If so, the user is not logged in.
Is this a safe method or should I choose a better way to have secure login/logout functions. Perhaps its better to create a userSessionBean after a succeful login and check it with HttpServletRequest rq.getSession().getAttribute(userSessionBean)?
I am confused a little bit and I hope you'll help me:)
Thnx Alex

Basic question about Java, UNIX and OAS

Hi,
Can I create an appication that contains GUI components like testbox and textfields etc...and then load/import it into OAS?
Can I again, create such an GUI application and then load it UNIX platform and run it?
The reason I asked because I did create an application which has a frame, a panel and couples of buttons, text fields then ftp it to Unix Solaris, when I ran it with jre command, I got the following message:
java.lang.NoClassDefFoundError: Javax/Swing/UIManager at cms.CMSApp.main(compiled code) Exception in thread main
Please anyone help me to clarify this, I don;t if we can do such things but I did not do it the right way? or we cannot do it at all. Thanks for your help
Minh

I'm not sure I understand where OAS fits in here.. Is this an applet?
In any case, it sounds like the JDK version you are using is 1.1.x, and swingall.jar is not in the classpath.
If it's an applet, then you need to edit the HTML file and add in swingall.jar.
If it's an application, you need to edit the CLASSPATH environment variable and append the full path to swingall.jar
(note: in Java2 (JDK 1.2, 1.3) swingall.jar is no longer seperate, it is part of the runtime classes of java, so you don't have to add anything to the classpath)
Take Care,

A basic question about static variables and methods

What would be the effects if I declare lots of static variables and static methods in my class?
Would my program run faster?
Would the class take more memory spaces? (If so, how do I estimate an appropriate number of variabls and methods to be declared static?)
Thank you @_@

when you declare a static var the var isn't created for every instance of the class, it just "live" in the class
when you declare a static method is the same, so if you have:
class MyClass
static int myMethod()
//Method work
you dont need to have a instance of the class to call myMethod, you can do such things like this.
int value = Myclass.myMethod();
if myMethod isn't static you can't do this.. so, if
class MyClass
int myMethod()
//Method work
you CAN'T call
int value = MyClass.myMethod();
instead, you have to write
MyClass m;
m = new MyClass();
value = m.myMethod();

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

Basic question about storage and safety in iMovie '11

A very basic question about storage and safety:
I want to keep a backup of my raw footage on my external hard drive prior to begin working on the movie in iMovie. I want to do this:
1. Upload the digital files from my camcorder to my Desktop *(as opposed to iMovie)*
2. Duplicate that footage/clips.
3. Put the duplicate clips/footage into a folder labeled with the name of that footage (like "Fun At the Dentist" or "Jimmy Learns How to Yodel").
4. Drag the folder with the footage/clips into my external hard drive into a pre-existing folder titled "Backups/duplicates of all of my raw footage/clips." This big granddaddy folder will house all of the child folders of different movies.
5 Then, open up iMovie '11 and import the raw footage/clips from my Desktop rather than from my camcorder.
6. Then I want to make a duplicate of my finished movie and put it in my external hard drive in a "Finished Movies" folder.
I know that the original raw unedited footage will always be in iMovies '11 but I want the original to also exist immediately accessible in my external hard drive.
QUESTION:
Is this viable? Is it wise? (I know it goes an extra unnecessary step, but aside from that.)
*Do you have any precautionary advice?* Should I do something in my iMovies '11 preferences? What?
In earlier years with iMovie '04 or '06 (cannot recall) I made many novice errors and ended up losing audio to my finished movie. I also lost footage.
This time around with iMovie '11 I don't to make such novice, ignorant errors.
Thanks so much for any comments to this question.

Yes I'm sure it will work great for you.
The iFrame format is something Apple has come up with. The reason for its existence is unknown to me so I can only speculate. But it seems to me that Apple "invented" this format in order to have devices such as Ipod/Ipad/Iphone/Ixxx create clips that are editable on consumer hardware such as already mentioned devices but also standard Mac computers, without the need for format conversion.
iMovie converts most input formats during import, which takes a lot of time, and this need for conversion often comes as a surprise to most people new to home video editing.
iFrame has a resolution of 960x540 which is long way from the common standards of 1920x1080 and 1280x720. If your end target is YouTube however, this may not be too bad though. However if you intend to go with YouTube HD, you may find iFrame footage to look wrong since they are effectively upscaled to a higher resolution.
Technically iFrame uses the H.264 algorithm, a smaller frame size (960x540) and a rather low compression scheme. This will result in large files, but the plus side is that the files are ready for editing without the need for any conversion and iMovie will natively edit the files.

Basic questions about Infocube

Hi, everyone.
I got very basic questions about infocube data handling.
With infopackage, I extracted all the data about employees from R/3.
But there were some mistakes during inputting employee data, like positions,
so I just extracted those employees data once more.
Now I have two requests in infocube, where the first one has some wrong data.
Is there any solutions about this?
I might got it all wrong, so as beginner, any suggestions and explanations will
be grateful.

Hi,
You can manually delete the earlier request by going in the Manage option of the cube. select the request and click on delete icon at the bottom.
Other option is to make setting in the Infopackage to delete similar or overlapping request.
Data target tab --> 6th column Automatic loading / deletion of similar request. --> click on the blank icon --> you will get a pop-up --> select the radio button - "delete existing request" --> Select Conditions --> Infosource are same, datasource are same and source system are same, --> selections are "Same or More Comprehensive "
Assign points if useful

Basic questions about macbook pro + external monitor

Hi,
I have some very basic questions about using a Macbook Pro + external display. I don't actually have them but need to know how things works.
So, here they are:
1) Can I use the external display as the main display?
2) Will the external display run with its resolution or with that of the mbook pro?
3) Somewhere I read that you cannot keep the macbook pro open and get the full resolution of the external display. Is that true ?
4) Is it dangerous to keep the mbook closed while using the external display?
5) Does the usage of the external display impact on mbook performance?
I know...a lot of questions , but would be nice if someone could help me.
Thanks.

Hi - I am presently using an external display.
To answer your questions in sequence:
1. Yes you can use the external display as your main display. The way to enable that mode is to put your MacBook Pro to sleep, attach the external display. Wake up your MBPro with the lid closed and you will see the external display as you main display. You can alternatively set the external to "Mirror" your notebook by using preferences/display.
2. The external display will run at its resolution although you can adjust and calibrate it using Preferences/Display.
3. Not true. You get max resolution on both displays. Of course you may have to tweak as mentioned above.
4. Not at all. I use this mode all the time. Just make sure you initially set up as mentioned above and your LCD on the MBPro will stay off.
5. I have not seen any performance degradation whatsoever.
Hope this helps.
