Right - I guessed "pre-populated" referred to things you already knew about the candidate before they filled out the form.

In that case, it really is just a case of stuffing the form fields into a PDF generator of your choice; no database required. If you want to store it, text files are fine, though databases handle locking and such for you if there might be simultaneous submits.

If you're having them fill out stuff like a W-2, you probably don't want to store that anywhere after you've sent it, given that it might contain confidential information (like SSN). In fact, you should probably do what you can to make sure that you delete the resulting form after it's been sent (or after you've given up trying to send it if there's a failure).

At work, we have an an HTML page on our LAN that gets periodically updated by a person who runs a MATLAB script that just modifies the HTML page. We want to reduce the number of MATLAB licenses, so someone suggested rewriting the script in Python and maybe just have it running as a cron job. This seems like a reasonable improvement, but is there a better way?

Sounds like a sensible solution. Depending on exactly how complex the HTML output needs to be, you might also benefit from a templating engine such as Jinja2. As long as you just need to generate static pages, you can do without a full application server stack, so you probably shouldn't bother looking into any of those.

Rocko Bonaparte: Mar 12, 2002; Every day is Friday!

I'm kind of curious about pathfinding algorithms and such for something I'm trying to write for Minecraft. One of the mods adds something called "turtles" which is kind of a homage to turtles in Logo. The mod uses Lua to program the things. To some extent, the API is kind of weak so that the whole thing doesn't become too overpowered, but I persist anyways. I've been trying to make a general-purpose builder that would work off a text file of a building plan When loaded, it gives it a 3d array, where each element is an ID for what material to place there, if any. Assuming, say, that I want to iterate every element inside this 3d array, I came up with a nice-enough algorithm that saves on movement and placement time (these operations do consume time and some turtle energy). However, it was meant to assume I visit every position of the 3d array. It gets more complicated when dealing with things like "don't care" elements, or especially "do not go" elements. So:

1. Given something that works by moving up, down, and turning
2. Some areas of off limits
3. Other areas need to be explicitly cleared, although nothing needs to be placed there
4. Some spots are not of any concern
5. The input is a 3d array of these elements, as well as some for spots where I need to place down something

Are there some basic algorithms to attempt to efficiently handle the situation that I can look up?

Say you have an area like this (. is to clear, X is "don't go there")

code:

XXXXX
X.X.X
X...X
X.XXX
 ^ (Turtle)

It's hard to figure out the optimal path to explore each route. It's kinda a travelling salesman problem if you break it down into routes. Which is NP-hard, so it's not something a really slowly updating program like a turtle could solve, even inefficiently. I think, at least. And then there's the cases of

code:

XXX
X.X
XXX

Where the turtle can't really "pathfind" to the point.

The best solution I'm thinking of right now is a floodfill where it starts from where the turtle is and floods outwards, using some kind of pathfinding to wherever the flood fill reaches a new area, to work out some semi-optimal routes around that avoid backtracking.

So if you had this:

code:

 ^X^ (Continues up to wherever)
X.X.X
X...X
X.X.X
X...X
X.XXX
 ^ (Turtle)

The floodfill would go up here (X's replaced with spaces for clarity)

code:

 ^ ^ (Continues up to wherever)
 5 7 
 476 
 3 5 
 234 
 1

And at the middle 7 it would say "okay, I can't spread any more, mark this as a path to go to" and will hit that path along the route of 1->6 following the shortest path branches then backing to the point where the branch began (6). Something like that. This seems to be basically tree traversal if you're looking for algorithms.

Another method would be:

Follow the closest path (floodfill, first dead end is closest)
Mark each tile you dig as "complete", floodfill again from that point and repeat.

Last method I can think about is segmenting the spots to dig into cubes, and pathfinding/clearing out based on those cubes rather than the individual tiles in them, but this method is a bit more complex, especially on such a rudimentary API.

With regards to placing blocks, I'd either separate dig/place into separate routines unless you can explicitly work out if placing a block won't obstruct you, or, check if you can place it while going backwards along the route after it's been marked as "completely cleared".

I think you have the right idea about what I was saying. All I could come up with was np-hard stuff too. That might be okay if the work size isn't really that disgusting. The biggest thing I want to build is a dome of diameter 120 blocks, going up something like 50 blocks. Well, that is 720000 blocks, so I have to kind of think about that. I guess there's also reducing the scale of the work set by trying to subdivide it and then having some alternate lookup for handling the seams. I was worried about things like unreachable spaces. For what I was doing, it shouldn't happen . . . on purpose. I could see in general use somebody could end up trying to do that when trying to make some mechanism or something else that in its initial state is completely enclosed.

My company has a grails webapp with spring security. We have a dev environment, and a test environment. They are running the same code. I have a User object, and a Role object, and a UserRole object on both of these environments. They're identical. When I call /data/roles/showAll on dev, it works properly. When I call /data/role/showAll on test, it returns the json {error:"access denied"}. What could possibly be causing this? How are you supposed to fix this? Why would the same program with the same inputs generate different outputs?

baby puzzle: Jun 3, 2011; I'll Sequence your Storm.

I have a lua script that needs to grab a recursive directory listing for a very large folder. I'm running on windows and I am using this thing called filefind https://github.com/jjensen/luaplus51-all/blob/master/Src/Modules/filefind/doc/us/index.md

The problem is that this can take up to 10 seconds (while users are waiting). I'm wondering if there is a faster way to do this. Since these folders don't change often, I'd like to cache off the data somehow... but how do I check the folder timestamps without doing the whole iteration anyway? Edit: subsequent runs will only take a fraction of the time because of OS caching, but that first run is always very slow.

How does something like git check tens of thousands of files for changes so quickly? Maybe this filefind thing is just slow?

I need some regular expression help. If I have a string containing a mix of Japanese kana and Roman characters, how can I match all continuous Roman characters and get it back as a single match?

For example, if I'm matching "ki", "kiく", "かki", or "かkiく", I want to get back "ki". Right now I'm using [a-zA-Z]* but this won't match anything if there's any kana in the string. I tried getting rid of the asterisk but that just returned single English letters at a time. How do I make this work?

What language? In any case, you might want to use [a-zA-Z]+ instead.

Python 3:

Python code:

In [1]: strings = ["ki", "ki&#12367;", "&#12363;ki", "&#12363;ki&#12367;"]

In [2]: import re

In [3]: pattern = re.compile('([a-zA-Z]+)')

In [4]: for i, s in enumerate(strings):
   ...:     m = pattern.search(s)
   ...:     if m:
   ...:         chars = m.group(1)
   ...:         print('String {} matched; chars extracted: {}'.format(i, chars))
   ...:
String 0 matched; chars extracted: ki
String 1 matched; chars extracted: ki
String 2 matched; chars extracted: ki
String 3 matched; chars extracted: ki

EDIT: damnit the HTML character escapes weren't in what I pasted here. Pretend that I typed strings = ["ki", "ki\u304f", "\u304bki", "\u304bki\u304f"] above, since at least vBulletin won't mangle \u character escape sequences.

EDIT 2: testing ["ki", "kiく", "かki", "かkiく"]

EDIT 3: okay, vBulletin seems to double-escape non-ASCII characters inside the [code] tag.

In grails, how do you save a list of objects to the DB with one database hit? Is there an easy way to say "here's a giant list of objects, put them all over there at once. I know some of these things have the same ID as other things, I don't care what they are, I want those gone and these in?"

In SQL Server you would pass table parameters to a stored procedure, then within it do INSERTs or UPDATEs (or MERGEs if you're really cool) to do everything in one shot. Other databases offer a special %rowtype to pass an array of rows to a stored procedure which IIRC can be used in a similar way.

Original question:

This is probably the most unintuitive way to do something, but here's my process:
I am trying to write a .bat file that will go through and iterate on a bunch of files. The problem that arises is that I'm trying to utilize a program to perform some manipulations on these files. The program opens an xml file, performs some an action, and that's it. The files are all numbered sequentially. The xml file stores the file name its working on. I want to be able to find the file name in the xml and since the file name is just a number, to iterate to the next file. The problem is, I cannot find the file name in the xml. I know it stores it somewhere in the xml because when I remove the file the xml refers to, it says "Cannot find file 28.jpg" for instance.

Any help towards how to locate the file name within the xml would be super appreciated. I have added the pastebin link at the bottom, so you can have a look at it. The file is named gt-GT.xml and the file that this particular xml file is looking for is 28.jpg. My best effort was to open the xml, ctrl+f and type in "28.jpg". It returns 0 results, but that's the extent of my knowledge.

Thanks in advance!

I'm pretty sure your presumptions about how the program works are incorrect. Why don't you just back up to the beginning and tell us what program it is, and what workflow you're trying to automate. In other words, if you wanted it to process each file, could you do so "by hand"?

To actually answer your question, I don't think the XML file is doing what you think it's doing. There are no filenames in there.

Gotcha.

I am trying to get some text from some images. The program I am trying to used is called GTText (https://code.google.com/p/gttext/downloads/list). I want to create a bat file to do this as I have ~ 300 images (sequentially numbered) to do this for.
When you load an image into the program you can then 'save as' and it will save and create an XML file. If you load the xml file via the program "file" -> "open project" it brings back up the image. You can run the program from a command line and pass into it the file name of an xml file to load and it will work and load the image. The file that I provided in the pastebin (http://pastebin.com/jKRZfgSn) is one such save file the program created.
Now, I know that somehow this program is directing itself towards 28.jpg via the save file. If I can find that reference, then I'd like to make a bat file that will edit the xml, load the program, process and image, paste the results in a notepad, then repeat through all the images I need done.

I don't know if there is an easier way to do this, but that's my plan thus far. I don't know if it will work, but I do know that to progress further with it I need to find where that 28.jpg is. I need to hunt it down, and I don't know what I'm doing with xml, pretty much.

Hmm. So you can load in a saved project (XML) from the command line but not an image?

For what you want to do, you shouldn't need to know anything about XML, just how to do as simple find/replace in text. However, everything in that XML seems generic. Maybe generate an XML for another file and then we can compare them?

OK so after some googling I'm pretty sure that the proper way to do this is to create an aggregator class for this object, then call save on the aggregator.

Okay, I found out that the GTText program actually creates 3 xml files, 2 in sub directories - one of which had the file info that I want to manipulate.

My problem is now this. http://pastebin.com/RjrFH8H6
I am trying to make a .bat file to go through the xml file to iterate 1.png through to 300.png. Right now I have the code limited to 5 just for testing purposes.

The problem is, I do not know why in the substitution line:

set newline=!newline:%%i.png=!number!!

it is not using the value for the variable 'number'. I have tried it with percent symbols (%number%) and with exclamation points (!number!) and neither seem to work. At one point I added a pause at the end of the script with echo enabled and I can see that the 'number' variable is being updated correctly. However, in the replace line of the code, it doesn't seem to recognize it as a variable.
I'm guessing that this is just a syntax error, but I don't know what 'language' I'm working with in a .bat file (if it even is one), much less the syntax for it. Most of what I have cobbled together is just different bits of code I've been able to google.

Any help would be appreciated

I appreciate it, but unfortunately, I don't know enough of the theory of what I'm working with to be able to apply what you linked for me. Can you tell me what I should look at, more specifically in the linked page? I looked at / tried to use some of the stuff in part 5 - the find and replace. When I did that my 'number' variable started working better, but the 'newline' variable stopped, haha.
I can tell that there are some specific rules that govern / define the usage and interbreeding of !'s and %'s, but I don't know what they are. I would look up more on my own, but I don't even know what 'language' I'm working with here.
I feel I'm super close to getting this working, but I just need to know how to get the 'number' variable in the replace line to be interpreted not-literally.

It varies both by jurisdiction (at least on a country-by-country basis; the US has less state-by-state variation here due to the exclusive federal patent and copyright regime) and type of intellectual property (copyrights and patents have wildly different answers in the United States, and software is treated specially by comparison to other copyrights in many countries).

Batch sucks but if you gotta use it, here:

Alternatively you should use PowerShell or really something like Cygwin so you can get a proper bash shell.

I've seen powershell hanging out on street corners, so I'll go take another look at it. My only concern is that its just another language I'll have to learn. I'm really just hoping for a quick fix as this is not something I need hardly ever. So hopefully powershell is pretty clean. I'll google cygwin, too, while I'm at it. Why the hell not.

e: More bad news, I'm on windows 8. I got sent to this site: http://www.microsoft.com/en-us/download/confirmation.aspx?id=34595 to get powershell, but there doesn't seem to be a version of the download for windows 8. Am I out of options?

I'm quite sure PowerShell is a core feature of Windows 8, not a separate download. You might have to enable it in the Turn Windows features on/off control panel on some versions.

Well look at that. You're absolutely right. Thanks. Okay, I have powershell! Yay!
Okay, now here is a new problem, haha. I am using this code:
http://pastebin.com/TiGxK3K4
to go through a text file containing "1.jpg 2.jpg 3.jpg 4.jpg 5.jpg".
I would expect that the output should be "2.jpg 3.jpg 4.jpg 5.jpg 6.jpg".
However, the output I'm getting is "6.jpg 6.jpg 6.jpg 6.jpg 6.jpg 6.jpg".
Its especially odd because if I change the ".jpg" in the code on either side of the search and replace portion:
(strNewText = Replace(strText, (intRep&".jpg"), (intNext&".jpg"))) so that both sides don't match, then it works fine. So if the second part is intRep&".cat" then my output is:
2.cat 3.cat 4.cat 5.cat 6.cat

I'm guessing this is a simple issue. Any ideas?

Your file initially contains:
1.jpg 2.jpg 3.jpg

In first iteration intRep is 1 and intNext becomes 2. You then replace all occurrences (a single one) of "1.jpg" with "2.jpg". Your file now contains:
2.jpg 2.jpg 3.jpg

In the next iteration, intRep becomes 2, and intNext becomes 3. You then replace all (two) occurrences of "2.jpg" with "3.jpg". Your file now contains:
3.jpg 3.jpg 3.jpg

One possible workaround is to do the replacement backwards, start with the largest number and work downwards.
