Most efficient way to add maintain items dynamically

Hi everyone,
I am going to build a website that delivers news and events
of a particular sport. I understand that I need to use RSS to
deliver news content but I was wondering about the other part of
what I want to do. I have come across sites that will have for
example, all upcoming basketball games for a specfic region. The
user can either search according to region or browse through,
sometimes very comprehensive, up to date listings. In my uneducated
mind, the only way I know how to build such an event listing is to
manually scour the web and enter each event into a database, then
of course use ColdFusion to "expire" the events when they have
passed. Or I could let the web community build the events
themselves, by allowing them to propose an event, then I as
administrator would validate and allow it to post. The problem is,
when building a new site, I would like it to be comprehensive from
the beginning. Is there any more dynamica way to do what I just
described in CF? Or any other way?
thank you,
SR

Take a look at the current websites that offer information
about the sporting events you are interested in. Do any of them
offer RSS feeds? If so, you can roll your own RSS aggregator to
pull the information down from them to use in your application.
Keep in mind:
In some cases, someone had to compile this data from a number
of different souces, which may mean the websites may have
restrictions on how the data in their feeds can be used.
If you are dealing with just one sport at just one level
(collegiate, NBA, etc) you can go directly to the site of the
overseeing body of the sport to see if you can obtain the data you
want in electronic format.

Most efficient way to add a lot of text?

Hey all,
I have a project for a client who wants me to make flash cards for 350 scripture passages. Basically the cards need the Passage name and number on the top, with the actual passage underneath. Originally I was looking up each passage online, copying it, and pasting it into a new text box one at a time. However, this is taking forever.
I was able to locate an XML Bible and was wondering if its at all possible to use that to speed up my process? Is it possible to set up the text boxes with the correct tags so that when I import the XML it fills them in with the proper specific passage? If not, is there an easier way to do this than one at a time?
I'm quite new to using XML with Indesign, so detailed advice would be appreciated! Thanks for any help!

Can you work with ready-to-place XML?
I've tinkered a bit with a file called KJV.XML and a custom style sheet, and came up with this scheme. All you have to do is fill the variable "list" with the names of the books and chapter and verse number, then save the style sheet.
Choose "Import XML", then select the file "KJV.XML" (since that's what the style sheet is based upon -- if you have another XML data file, the names of the individual elements may not match). In the dialog, select "Choose XSLT"; browse for the XSLT file and select that. ID will import the verses as "quote", with the name of the book and verse in a tag "title" and the text itself in a tag "verse". From then on you'd have to consult someone who knows how to process it any further
This is the style sheet -- copy, paste into a plain text editor, and save as "verses.xslt". The variable you should fill in is on line #6; be sure to use a comma to separate Book name and verse, and put a colon between chapter and verse number. Hope it works for you!

The most efficient way to search a large String

Hi All,
2 Quick Questions
QUESTION 1:
I have about 50 String keywords -- I would like to use to search a big String object (between 300-3000 characters)
Is the most efficient way to search it for my keywords like this ?
if(myBigString.indexOf("string1")!=1 || myBigString.indexOf("string2")!=1 || myBigString.indexOf("string1")!=1 and so on for 50 strings.)
System.out.println("it was found");
QUESTION 2:
Can someone help me out with a regular expression search of phone number in the format NNN-NNN-NNNN
I would like it to return all instances of that pattern found on the page .
I have done regular expressions, in javascript in vbscript but I have never done regular expressions in java.
Thanks

Answer 2:
If you have the option of using Java 1.4, have a look at the new regular expressions library... whose package name I forget :-/ There have been articles published on it, both at JavaWorld and IBM's developerWorks.
If you can't use Java 1.4, have a look at the jakarta regular expression projects, of which I think there are two (ORO and Perl-like, off the top of my head)
http://jakarta.apache.org/
Answer 1:
If you have n search terms, and are searching through a string of length l (the haystack, as in looking for a needle in a haystack), then searching for each term in turn will take time O(n*l). In particular, it will take longer the more terms you add (in a linear fashion, assuming the haystack stays the same length)
If this is sufficient, then do it! The simplest solution is (almost) always the easiest to maintain.
An alternative is to create a finite state machine that defines the search terms (Or multiple parallel finite state machines would probably be easier). You can then loop over the haystack string a single time to find every search term at once. Such an algorithm will take O(n*k) time to construct the finite state information (given an average search term length of k), and then O(l) for the search. For a large number of search terms, or a very large search string, this method will be faster than the naive method.
One example of a state-search for strings is the Boyer-Moore algorithm.

What is the most efficient way to post several stories to multiple html pages

What is the most efficient way to post five stories to multiple html pages?

What is the best, most efficient way to read a .xls File and create a pipe-delimited .csv File?

What is the best and most efficient way to read a .xls File and create a pipe-delimited .csv File?
Thanks in advance for your review and am hopeful for a reply.
ITBobbyP85

You should have no trouble doing this in SSIS. Simply add a data flow with connection managers to an existing .xls file (excel connection manager) and a new .csv file (flat file). Add a source to the xls and destination to the csv, and set the destination
csv parameter "delay validation" to true. Use an expression to define the name of the new .csv file.
In the flat file connection manager, set the column delimiter to the pipe character.

Most efficient way to place images

I am composing a Catalog with a lot of images along with the text. The source images are often not square (perfectly vertical, portrait). I also want to add a thin line frame around each one in InDesign to spurce up the look. I'm spending a lot of time in Photoshop straightening images, because rotating in Indesign to get the image straight results in a non-straight frame.
Should I create a small library of frames that I place, then place non-straight images in them (and how do I do that) and rotate in InDesign? Etc?
What would be the most efficient way to do this?
Thanks

To tag onto what Peter said, when you click on the image with the Direct Selection tool you can also use the up and down arrow in the rotation Dialog (where you enter the angle, at the top) to easily change the rotation.
Also, when you place images in InDesign you can select a number of images at once and continually click the document (or image frame) and place all the images you selected to import. To clarify, you can have a whole bunch of empty image frames on the page then go to file > place and select all your images, then continually click and place them inside each empty frame.

Most efficient way to consume log files

Hello everyone,
I've been absent from the forums for awhile but I'm back at it now...
I have a question about the most efficient way to consume log files. I read in Powershell in action, by Bruce Payette that using a switch statement with a regex worked pretty well, that being said I haven't tried it yet. Select-string is working pretty
well for me but I have about 10 different entry types that I need to search logs for every 5 minutes and I'm scanning about 15 GB of logs at every interval. Anyway, if anyone has information about how to do something like that as quickly as possible
I'd appreciate it.
1. piping log files that meet my criteria to select-string
- This seems to work well but I don't like searching the same files over and over again
2. running logs through get-content and then building a filter statement
- This is ok but it seems to use up a fair bit of memory
3. Some other approach that I haven't thought of yet.
Anyway, I know this is a relatively nebulous question, sorry about that. I'm hoping that someone on here knows a really good way to find strings in logs files quickly.
Hope that helps! Jason

You can sometimes squeeze out more speed at the expense of memory usage, but filters are pretty fast. I don't see a benefit to holding the whole file in memory, in this case.
As I mentioned earlier, though, C# code will usually blow PowerShell away in terms of execution time. Here's a rewrite of what I just did (just for the INI Section pattern, to keep the post size down):
$string = @'
#Comment Line
[Ini-Style Section Line]
Key = Value Line
192.168.0.1 localhost
Some line that doesn't match anything.
Set-Content -Path .\test.txt -Value $string
Add-Type -TypeDefinition @'
using System;
using System.Text.RegularExpressions;
using System.Collections;
using System.IO;
public interface ILineParser
object ParseLine(string line);
public class IniSection
public string Section;
public class IniSectionParser : ILineParser
public object ParseLine(string line)
object o = null;
Match match = Regex.Match(line, @"^\s*\[([^\]]+)\]\s*$");
if (match.Success)
o = new IniSection() { Section = match.Groups[1].Value };
return o;
public class LogParser
public static IEnumerable ParseFile(string fileName, ILineParser[] lineParsers)
using (StreamReader sr = File.OpenText(fileName))
string line;
while ((line = sr.ReadLine()) != null)
foreach (ILineParser parser in lineParsers)
object result = parser.ParseLine(line);
if (result != null)
yield return result;
$parsers = @(
New-Object IniSectionParser
$results = [LogParser]::ParseFile("$pwd\test.txt", $parsers)
$results
Instead of defining separate classes for each type of line and output object, you could probably do something more generic with delegates (similar to how I used ScriptBlock.Invoke() in the PowerShell example), but it might sacrifice some speed to do so.

Best way for add thousans items to listbox without freezing ui in wpf

Hello guys.
What is the best way for add thousands items (or even more) to Listbox without freezing UI.
I search many post in the web but I don't understand how this posts writer wrote that code.
I realized that ObservableCollection can contain 1000 items or even more and show that items to listbox just for few second without freezing UI but I don't Know how can I use that!
Can you guys give me an example.
thanks.

If you bind an observablecollection you can add items to that from a background thread. Then bind that to the itemssource. I usually new up an observablecollection, add the items then set the bound property to that.
But I avoid thousands of items.
You should provide some sort of filter mechanism the user chooses a category or whatever and then fill with a maximum of 300 items.
Users simply can't work with thousands of items.
It is usually reading the data out a database which takes the time rather than creating objects to bind.
Hence this:
protected async override void GetData()
ThrobberVisible = Visibility.Visible;
ObservableCollection<CustomerVM> _customers = new ObservableCollection<CustomerVM>();
var customers = await (from c in db.Customers
orderby c.CustomerName
select c).ToListAsync();
foreach (Customer cust in customers)
_customers.Add(new CustomerVM { IsNew = false, TheEntity = cust });
Customers = _customers;
RaisePropertyChanged("Customers");
ThrobberVisible = Visibility.Collapsed;
That's making an asynchronous entity framework call.
A list of customers is obtained.
These are then wrapped in a customer viewmodel each.
Finally the observablecollection Customers is set to this new collection and propertychanged raised to notify the view.
The itemssource of a datagrid is bound to Customers.
Hope that helps.

What's the most efficient way to serve a file from a servlet?

I have a servlet that does various different things depending on the needs. Sometimes it dynamically generates content, and sometimes all it does is send a file out, with no alteration.
What is the most efficient way to just send a file?
One option:
OutputStream os = response.getOutputStream();
InputStream is = new FileInputStream(...)
(send all the bytes from is to os, the regular way using a buffer)Another option is to say:
RequestDispatcher rd = response.getRequestDispatcher(fileName);
rd.forward();Any other options? What's the prefered way of doing this?
I know the rule of "don't optimize too early" but this is a situation where we need to get the maximum amount of files served with the hardware we have, and it's going to be a lot of static files, so efficiency is important.
Thanks

Ok, that's what I thought. It would be nice if there were a "response.sendStream(InputStream input)" method in the ServletResponse class. Even nicer would be a sendFile or sendChannel or something. This is probably a common usage and it's a place where the container has many opportunities for optimization. For example, it could call the operating systems send_file kernel call so the entire transfer would be done directly from the disk controller to the ether card (on systems that support that).
For now I'll just do my own buffered copy.

Most efficient way to delete "removed" photos from hard disk?

Hello everyone! Glad to have this great community to come to for help. I searched for this question but came up with no hits. If it's already been discussed, I apologize and would love to be directed to the link.
My wife and I have been using LR for a long time. We're currently on version 4. Unfortunately, she's not as tech-savvy or meticulous as I am, and she has been unknowingly "Removing" photos from the LR catalogues when she really meant to delete them from the hard disk. That means we have hundreds of unwanted raw photo files floating around in our computer and no way to pick them out from the ones we want! As a very organized and space-conscious person, I can't stand the thought. So my question is, what is the most efficient way to permanently delete these unwanted photos from the hard disk
I did fine one suggestion that said to synchronize the parent folder with their respective catalogues, select all the photos in "Previous Import," and delete those, since they will be all of the photos that were previously removed from the catalogue.
This is a great suggestion, but it probably wouldn't work for all of my catalogues since my file structure is organized by date (the default setting for LR). So, two catalogues will share the same "parent folder" in the sense that they both have photos from May 2013, but if I synchronize May 2013 with one, then it will get all the duds PLUS the photos that belong in the other catalogue.
Does anyone have any suggestions? I know there's probably not an easy fix, and I'm willing to put in some time. I just want to know if there is a solution and make sure I'm working as efficiently as possible.
Thank you!
Kenneth

I have to agree with the comment about multiple catalogs referring to images that are mixed in together... and the added difficulty that may have brought here.
My suggestions (assuming you are prepared to combine the current catalogs into one)
in each catalog, put a distinctive keyword onto all the images so that you can later discriminate these images as to which particular catalog they were formerly in (just in case this is useful information later)
as John suggests, use File / "Import from Catalog" to bring all LR images together into one catalog.
then in order to separate out the image files that ARE imported to LR, from those which either never were / have been removed, I would duplicate just the imported ones, to an entirely separate and dedicated disk location. This may require the temporary use of an external drive, with enough space for everything.
to do this, highlight all the images in the whole catalog, then use File / "Export as Catalog" selecting the option "include negatives". Provide a filename and location for the catalog inside your chosen new saving location. All the image files that are imported to the catalog will be selectively copied into this same location alongside the new catalog. The same relative arrangement of subfolders will be created there, for them all to live inside, as is seen currently. But image files that do not feature in LR currently, will be left behind by this operation.
your new catalog is now functional, referring to the copied image files. Making sure you have a full backup first, you can start deleting image files from the original location, that you believe to be unwanted. You can do this safe in the knowledge that anything LR is actively relying on, has already been duplicated elsewhere. So you can be quite aggressive at this, only watching out for image files that are required for other purposes (than as master data for Lightroom) - e.g., the exported JPG files you may have made.
IMO it is a good idea to practice a full separation of image files used in your LR image library, from all other image files. This separation means you know where it is safe to manage images freely using the OS, vs where (what I think of as the LR-managed storage area) you need to bear LR's requirements constantly in mind. Better for discrete backup, too.
In due course, as required, the copied image files plus catalog can be moved bodily to another drive (for example, if they have been temporarily put on an external drive, and you want to store them on your main internal one again). This then just requires a single re-browsing of their parent folder's location, in order to correct LR's records inside this catalog, as to the image files' changed addresses.
If you don't want to combine the catalogs into one, a similar set of operations as above, can be carried out for each separate catalog you have now. This will create a separate folder structure in each case, containing just those duplicated image files. Once this has been done for all catalogs, you can start to clean up the present image files location. IMO this is very much the laborious and inflexible option, so far as future management of the total body of images is concerned... though there may still be some overriding reason for working that way.

Most efficient way to open a new TextEdit doc at a specific place

Suppose I've navigated in the Finder to some deep dark location in the folder hierarchy... I want a new text file titled "notes" in this folder, i.e. to this path.
Assuming TextEdit is already open, what is the most efficient way of creating and begin adding text to a new TextEdit file in that location?
Tried this: Maybe the usual Save dialog is aware of the current folder, so I can choose "New Document" in TextEdit's Dock icon pulldown, and then choose that path when I do File --> Save, choose the Save dialog's expanded view, and pull down the Where: selection. Nope. The current path is not there.
Tried this: Keeping an empty TextEdit document named untitled on my desktop. Drag-copying that to the current folder. Rename the file to "notes", open it, and start editing That works, except it is clumsy.
Is there a better way?
Please forgive me if I'm missing something incredibly obvious.

The problem with that is a new file has nothing in it.
If you save a dummy file on the desktop someplace or use a real file in each of your locations, you could right click and duplicate it, then doubleclick to open it in the program of choice.
Another option would to be to create a AppleScript that took the current open windows pathname and create and save a Textfile there.
You save the app in the Dock and only have to click on it once, it automatically quits when mission accomplished.

Most efficient way to load XML file data into tables

I have a complex XML file running into MBs. I want to load it's data into 7-8 tables.
Which way will be better:
1) Use SQL Loader to actually load directly into the 7-8 tables directly by modifying the control card.
Is this really possible and feasible? I am not even sure about it
2) Load data as XML Type in a table and register it. Then extract from there to load into various tables.
Please help. I have to find the most efficient way of doing it.
Regards,
Sudhir

Yes it is possible to use SQL*Loader to parse and load XML, but that is not what it was designed for and so is not recommended. You also don't need to register a schema, just to load/store/parse XML in the DB either.
So where does that leave you?
Some options
{thread:id=410714} (see page 2)
{thread:id=1090681}
{thread:id=1070213}
Those talk some about storage options and reading in XML from disk and parsing XML. They should also give you options to consider. Without knowing more about your requirements for the effort, it is difficult to give specific advice. Maybe your 7-8 tables don't exist and so using Object Relational Storage for the XML would be the best solution as you can query/update tables that Oracle creates based off the schema associated to the XML. Maybe an External Table definition works better for reading the XML into the system because this process will happen just once. Maybe using WebDAV makes more sense for loading XML to be parsed (I don't have much experience with this, just know it is possible from what I've read on the forums). Also, your version makes a difference as you have different options available depending upon the version of Oracle.
Hope all that helps as a starter.

Most efficient way to do some string manipulation

Greetings,
I need to cleanse some data in a string by replacing unsafe characters with encoded equivalents. (FYI, this is for the purpose of transforming "unsafe" characters into encoded values as data inside an XML document).
The following code accomplishes the task:
Note that a string "currentValue" contains the data to be cleansed.
A string, "encodedValue" contains the result.
for (counter = 0; counter < currentValue.length(); counter++)
    addChar = (currentValue.substring(counter,counter+1));
    if (addChar.equals("<"))
      addChar = "#60;";
    if (addChar.equals(">"))
      addChar = "#62;";
    if (addChar.equals("="))
      addChar = "#61;";
    if (addChar.equals("\""))
      addChar = "#34;";
    if (addChar.equals("'"))
      addChar = "#39;";
    if (addChar.equals("'"))
      addChar = "#39;";
    if (addChar.equals("/"))
      addChar = "#47;";
    if (addChar.equals("\\"))
      addChar = "#92;";
    encodedValue += addChar;
} // forI'm sure there is a way to make this more efficient. I'm not exactly "new" to java, but I am learning on my own with no formal training and often take a "brute force" approach with my initial effort.
What would be the most efficient way to re-do the above?

im a c++ programmer so im not totally up on these java classes either but...from a c++ stand point you might want to consider using the if else statment.
by using if else, you only test the character until you find the actual "violating" character and skip the rest of the tests.
also, you might trying using something to check for alphaNumeric cases first and use the continue keyword when you find one. since more of your characters are probably safe than unsafe you can skip all the ifs/if else statement and only do one test on the good characters. (i just looked for a way to test that and i didnt find one. c++ has a function that does that by checking the ascii number range. dont think that works in java. but maybe you can find one, it would reduce the number of tests probably.)
happy hunting,

Most efficient way to apply Paragraph Style A to Paragraph style B?

I'm looking for the most efficient way to all
all aspects of an existing named paragraph style "A" to another named paragraph style "B". I'd especially like to find a keyboard-only way to do this.
To my surprise,
Copy Special >
Paste doesn't seem to copy tab settings...(?) This leads me to suppose that other aspects of the source p'style may not be crossing the Great Paste Divide.
Over the years I've used a variety of more or less clumsy multi-step, multi-tool "tricks" (including third-party plug-ins) to apply one named paragraph style to another, but knowing FrameMaker as I do I suspect there may be a truly efficient way to do what I want.
Is there?
Cheers & thanks,
Riley

Arnis:
8.0p277.
The Font family and style got Pasted -- that was immediately apparent. And based on all I know about F'Maker, I would've thought the tabs would go over.
But when I opened the target p'style the Tabs area was completely blank.
I'm not sure if anything else wasn't making it 'cross the Paste Divide: Once the Tabs weren't Pasted, I fell back to a different, brute-force strategy simply to get around the problem and return to work...
Moreover, since the structured templates I inherited for this project are full of idiosyncrasies, I'll just file this one away under "The Templates Did It" and hope for better luck the next time I try the Copy Special thing...
Cheers & thanks for your help,
Riley
