Basic questions re zip, compression, and e-mailing large attachments

Hi, I have never really understood what is meant by "zip" and compressing a file.
I believe these things make it possible to make a file smaller for sending via e-mail, and then when the person at the other end opens up the attachment, it returns to its full size in all its glory.
Is this true?
Reason I ask is that I have a couple of .mov files that I want to send as attachments to a friend, but they are both mammoth in size--1 gig each.
I know it's probably a lost cause, but can compressing and zip help me out here? Thanks for your patient replies.

Yes, that's right. Read this to see how. http://docs.info.apple.com/article.html?path=Mac/10.6/en/8726.html. You'll have to experiment to see if you save enough space to send by email. Different Internet providers have different max file limits. Just try a test email attachment. Your sig says 10.5.8 and the article is for 10.6 but hopefully it is the same.

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,

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.

I receive and e-mail with attachments but when I forward them, the attachments are smaller. how to fix this?

I receive e-mails with attachments, but when I forward them the attachments are reduced in size. What do I need to do to have them forwarded the same size as I received them?

If the attachments are photos, when you forward them, look on the bottom right of your compose window, change to "actual size". It's probably set to small as displayed here:

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?

Very basic questions on JAX-RPC and wscompile

Hello,
well, I have this tool that generates java packages. The thing is that this tool needs now to generate JAX-RPC compliant java packages. To verify its compilance, I am using wscompile 1.1.3 build R1 and Sun AS Edition 8.2.
My questions are:
- In the generated packages, there might some classes with no attributes at all :P(remember that I am handling automatically generated classes). When running wscompile to generate the corresponding WSDL, I am getting "invalid type for JAX-RPC structure", even if it has a default empty constructor. I know it looks stupid, but I could not find anywhere in the JAX-RPC specification saying that for a class to be jaxrpc compliant, it must have at least one attribute. Any idea?
- It might be the case that I have same class name in different packages:
mypackage.structures.messages.A
mypackage.structures.segments.AWhen generating the server stub, I am getting:
Duplicate type name "{urn:mynamespace}A" for java type "mypackage.structures.segments.A" found.
Is there a way to tell wscompile to keep the class package name for every class when generating the wsdl? Or is it always building all the classes together in the package specified in the service/packageName within the configuration xml file?
Thanks a lot in advance for any help.

1. Does predictive text only work in the SMS app, or does it work in the apps for email, writing notes, etc?
It works with Safari, the Mail client, the Notes app, and with the SMS app.
2. Can you turn the predictive text off? (I find it wildly irritating, because I know far better what words I want to write than a pesky phone does!)
Yes.
3. Having email sent to a mobile is a whole new world for me! Do I need to subscribe to MobileMe at £££ per month, or is there another way of having email from my three accounts forwarded to my mobile?
You can access any IMAP or POP account with the iPhone's Mail client, and access multiple email accounts. I currently access to email accounts with the iPhone's mail client - my MobileMe account, and a business POP account. You can access all 3 of your email accounts with the iPhone's Mail client.

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 question related to EKKO and EKPO

Hi experts,
I have invoice document header and line item data in an internal table(From RBKP and RSEG). From RSEG I have PO number(EBELN) and PO line item(EBELP).
I want to find out the corresponding WBS element, costcenter and GL account of the PO number and the PO line item.
Can anybody tell me which tables to select to fetch WBSelement(PS_PSP_PNR), glaccount(SAKNR) and costcenter(KOSTL).
In which table I will find the link between EBELN,EBELP with KOSTL,SAKNR and WBS element?

Basic Questions on Spaces, Tabs and File Uploads

hi, new to the language. I have some data that has multiple spaces (not fixed) or multiple tabs as delimiters. How do I recognize the delimiters? Was easy in perl!!
Another question, am trying to upload files to the application. Is there any elegant way to upload multiple files? Or even specify a directory on the client and have the application read the directory and upload all files in the directory?
Thanks in advance

Questions on pipe channel and e-mail processing

Hi There,
We currently have a sendmail (on Solaris) based system that we use for our primary MTA. Our iMS5.2 (on Solaris 8) is used for message storage. We will want to migrate our sendmail system to the Iplanet MTA. However, I need some ideas on how to handle one of our scenarios: We have numerous sendmail aliases that pipe the message through a script. That script will then send a notification message to a group of users and then archive the E-mail into a directory.
I've looked at the docs regarding the "pipe" channel. It looks like I could define a bogus "alias-pipe" user and use the mailAlternateAddress field to define my various alias destinations. Then the script could just "switch" on the destination user to perform whatever actions are necessary. Everything I've read seems to indicate that processing e-mail through a program requires defining a user and that user then specifies the method to use. That requires "registering" the method using the "imsimta program" mechanism. I'd like to minimize the amount of work involved with updating and adding new alias programs. Does the above solution make sense, or am I headed down a deadend? Is there a better way to do this?
If I were to use the MTA's aliases file, could I send directly to the pipe channel?
Thanks for your input,
Roger S.

Roger-
We are in exactly the same boat as you. Migrating from sendmail (AIX) to iMS 5.2 on Solaris. Everything is done except for trying to figure out how to handle the old sendmail aliases file. All indication are that the aliase would optimally reside in the LDAP. I'm looking into the unix2ldif utility to see if I can figure out some way of getting it to work. We have hundreds (literally) of aliases that need to be incorporated into our iMS environment. Currently iMS is our primary server running a SmarHost to our old sendmail box for the sole purpose of maintaining the aliases file. I'm anxious to get moved off of the old beast. I would be very interested to hear any solution you come up with. I have been dissapointed in the iMS documentation in the regard.

Basic questions on Java platform and JDK

Hello,
I have a few questions, might be very elementary. Please clarify.
(Tried in "New to Java" Forum....but did not get much response)
What I know is : A "Java Platform" is composed of the Java language, a JVM, and the APIs. There is a spec. for the language, and another spec for JVM. Now, are there spec.s for the API as well ?
Another related question is : where exactly do the various flavours of the Java Platform (J2SE, J2EE, J2ME) differ ? I have seen some explanations where it seems to say that these editions have been created to give more appropriate support to different areas of applications. But, what I know to know is : what exact component of the Java Platform differs from one edition to another - language features, or the JVM, or the APIs ? And what is the kind of the change ?
Another question : what is it, that differs from one JDK release to another, say from J2SE 1.3 to J2SE 1.4.0 ?
I think the Java language spec itself rarely changes (Is this right?). Also the VM spec rarely changes (is this correct ?). So, is it that only the APIs change (new classes added, old ones modified, etc.) ?

[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 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 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.
