I am coding an rss reader and I believe I made the wrong choice in using xml over a sqlite database to store a cache of _all_ the feeds items. There are some feeds which have an xml file of ~1mb after a month, another has over 700 items, while most only have ~30 items and are ~50kb in size after a _several_ months.
I currently have no plans to implement a cap because I like to be able to search through everything.
So, my questions are:
1. When is the overhead of sqlite/databases justified over using xml?
2. Are the **few large xml files** justification enough for the database when there are **a lot of small** ones, though even the small ones will grow over time?

in front of them, and every now and then one or some of them hang.
No activity is seen in the database (we're using activerecord sessions).
Mysql with innodb tables. show innodb status shows no locks. show

The server is linux debian 4.0
Ruby is: ruby 1.8.6 (2008-03-03 patchlevel 114) [i486-linux]
Rails is: Rails 1.1.2 (yes, quite old)
We're using the native mysql connector (gem install mysql)
"strace -p PID" gives the following in a loop for the hung mongrel
process:
gettimeofday({1219834026, 235289}, NULL) = 0
select(4, [3], [0], [], {0, 905241}) = -1 EBADF (Bad file descriptor)

gettimeofday({1219834026, 236367}, NULL) = 0
...
I used lsof and found that the process used 67 file descriptors (lsof -p
PID |wc -l)
Is there any other way I can debug this, so that I could for example
determine which file descriptor is "bad"?
Any other info or suggestions? Anybody else seen this?
The site is fairly used, but not overly so, load averages usually around
0.3.
---
Some additional info. I installed mongrelproctitle to show what the
hung processes were doing, and it seems they are hanging on a method
that displays images using file_column / images from the database /
rmagick to resize and make the images greyscale.
Not conclusive the
problem is here, but it is a suspicion.
Is there something obviously wrong with the following? The method
displays a static image if the order doesn't contain an image, else the
image resized from the order. The cache stuff is so that the image gets
updated in the browser every time. The image is inserted in the page
with a normal image tag.
code:
def preview_image
@order = session[:order]
if @order.image.nil?
@headers['Pragma'] = 'no-cache'
@headers['Cache-Control'] = 'no-cache, must-revalidate'
send_data(EMPTY_PIC.to_blob, :filename => "img.jpg", :type =>
"image/jpeg", :disposition => "inline")
else
@pic = Image.read(@order.image)[0]
if (@order.crop)
@pic.crop!(@order.crop[:x1].to_i, @order.crop[:y1].to_i,
@order.crop[:width].to_i, @order.crop[:height].to_i, true)
end
@pic.resize!(103,130)
@pic = @pic.quantize(256, Magick::GRAYColorspace)
@headers['Pragma'] = 'no-cache'
@headers['Cache-Control'] = 'no-cache, must-revalidate'
send_data(@pic.to_blob, :filename => "img.jpg", :type =>
"image/jpeg", :disposition => "inline")
end
end
Here is the lsof output if anybody can find any problems in it. Don't
know how it will format in this message...

gettimeofday({1219834026, 236367}, NULL) = 0
...
I used lsof and found that the process used 67 file descriptors (lsof -p
PID |wc -l)
Is there any other way I can debug this, so that I could for example
determine which file descriptor is "bad"?
Any other info or suggestions? Anybody else seen this?
The site is fairly used, but not overly so, load averages usually around
0.3.
---
Some additional info. I installed mongrelproctitle to show what the
hung processes were doing, and it seems they are hanging on a method
that displays images using file_column / images from the database /
rmagick to resize and make the images greyscale.
Not conclusive the
problem is here, but it is a suspicion.
Is there something obviously wrong with the following? The method
displays a static image if the order doesn't contain an image, else the
image resized from the order. The cache stuff is so that the image gets
updated in the browser every time. The image is inserted in the page
with a normal image tag.
code:
def preview_image
@order = session[:order]
if @order.image.nil?
@headers['Pragma'] = 'no-cache'
@headers['Cache-Control'] = 'no-cache, must-revalidate'
send_data(EMPTY_PIC.to_blob, :filename => "img.jpg", :type =>
"image/jpeg", :disposition => "inline")
else
@pic = Image.read(@order.image)[0]
if (@order.crop)
@pic.crop!(@order.crop[:x1].to_i, @order.crop[:y1].to_i,
@order.crop[:width].to_i, @order.crop[:height].to_i, true)
end
@pic.resize!(103,130)
@pic = @pic.quantize(256, Magick::GRAYColorspace)
@headers['Pragma'] = 'no-cache'
@headers['Cache-Control'] = 'no-cache, must-revalidate'
send_data(@pic.to_blob, :filename => "img.jpg", :type =>
"image/jpeg", :disposition => "inline")
end
end
Here is the lsof output if anybody can find any problems in it. Don't
know how it will format in this message...

(So, only a certain section of the page would be displayed)
For example:
1) You have a large application with many entities (Customers, Products, Stores, etc, etc etc)
2) Each entity has an EntityDetails aspx page
Now, say from an Invoice screen that shows many entities of different types, I would like to be able to mouseover (or click a small icon) an entity, and have a little tooltip style modal ajax window popup, and what is shown will be the PORTION of the corresponding EntityDetails aspx page that was designated as available for rendering as a popup.
Obviously, the corresponding aspx arguments identifying the specific entity would have to be passed from the page as well.
So to do this, ** I think the requested page would have to be rendered in memory on the server **, and then the innerhtml would have to be pulled out of the designated div, and returned to the calling page, which would then display this html in a popup ajax window.
So, unless there is an easier way to do this that I am missing, how would this rendering be done on the server?
Has anyone seen this done before, is there any sort of a pre-existing framework or anything to do this?
And to complicate things further, would it be possible to have the popup form be editable and saved back to the server utilizing the existing asp.net form mechanism already embedded within the existing page (if the calling form already had an asp.net form....I think only one form is allowed per page, correct?)
And of course, opening the EntityDetails form via a simple javascript popup or new window is not what I am looking for. And I do not want to have to embed the details form on each page where I may want it to display...every form in the application could conceivably call any other as a popup.
Thanks!

For example, if UserDetails.aspx is used to edit and save a users information, if someone with inappropriate permissions enter the page, I would like to render it as read-only. So, most controls would be converted to labels, loaded with the corresponding data from the editable original control.
I think it would likely be a fairly simple routine, ie:
Dim ctlParent As Control = Me.txtTest.Parent
Dim ctlOLD As TextBox = Me.txtTest
Dim ctlNEW As Label = New Label
ctlNEW.Width = ctlOLD.Width
ctlNEW.Text = ctlOLD.Text
ctlParent.Controls.Remove(ctlOLD)
ctlParent.Controls.Add(ctlNEW)
...is really all you need for a textbox --> label conversion, but I was hoping someone might know of an existing function out there as there are likely a few pitfalls here and there with certain controls and situations.

When viewed via the ASP.NET control, it looks correct. But after export to XLS, it creates borders around all of the header cells (column and row headers, and the top left cell), and even the right most data column.

We are developing a system in C# 3.0 with a relatively big class hierarchy. Some of these classes, anywhere in the hierarchy, have resources that need to be
disposed of, those implement the **IDisposable** interface.
## The Problem ##
Now, to facilitate maintenance and refactoring of the code I would like to find a way, for classes implementing IDisposable,
to "automatically" call **base.Dispose(bDisposing)** if any ancestors also implements IDisposable. This way, if some class higher up in the hierarchy starts implementing
or stops implementing IDisposable that will be taken care of automatically.
The issue is two folds.
- First, finding if any ancestors implements IDisposable.
- Second, calling base.Dispose(bDisposing) conditionally.
The first part, finding about ancestors implementing IDisposable, I have been able to deal with.
The second part is the tricky one. Despite all my
efforts, I haven't been able to call base.Dispose(bDisposing) from a derived class. All my attempts failed. They either caused
compilation errors or called the wrong Dispose() method, that is the most derived one, thus looping forever.
The main issue is that you **cannot actually refer to base.Dispose()** directly in your code if there is no such thing as an
ancestor implementing it (*be reminded that there might have no ancestors yet implementing IDisposable, but I want the derived code to be ready when and if such
a thing happens in the future*). That leave us with the **Reflection** mechanisms, but I did not find a proper way of doing it. Our code is quite filled with
advanced reflection techniques and I think I did not miss anything obvious there.
## My Solution ##
My best shot yet was to have some conditional code using in commented code. Changing the IDisposable hierarchy would either break the build
(if no IDisposable ancestor exists) or throw an exception (if there are IDisposable ancestors but base.Dispose is not called).
Here is some code I am posting to show you what my Dispose(bDisposing) method looks like. I am putting this code at the end of all the Dispose()
methods throughout the hierarchy. Any new classes are created from templates that also includes this code.
public class MyOtherClassBase
{
// ...
}
public class MyDerivedClass : MyOtherClassBase, ICalibrable
{
private bool m_bDisposed = false;
~MyDerivedClass()
{
Dispose(false);
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool bDisposing)
{
if (!m_bDisposed) {
if (bDisposing) {
// Dispose managed resources
}
// Dispose unmanaged resources
}
m_bDisposed = true;
Type baseType = typeof(MyDerivedClass).BaseType;
if (baseType != null) {
if (baseType.GetInterface("IDisposable") != null) {
// If you have no ancestors implementing base.Dispose(...), comment
// the following line AND uncomment the throw.
//
// This way, if any of your ancestors decide one day to implement
// IDisposable you will know about it right away and proceed to
// uncomment the base.Dispose(...) in addition to commenting the throw.
//base.Dispose(bDisposing);
throw new ApplicationException("Ancestor base.Dispose(...) not called - "
+ baseType.ToString());
}
}
}
}
**So, I am asking is there a way to call base.Dispose() automatically/conditionally instead?**
## More Background ##
There is another mechanism in the application where all objects are registered with a main class. The class checks if they implement IDisposable.
If so, they are disposed of properly by the application. This avoids having the code using the classes to deal with
calling Dispose() all around by themselves. Thus, adding IDisposable to a class that has no ancestor history of IDisposable still works perfectly.

The software architecture involves a kernel driver that reads data into a pool of buffers, and a userland app that writes the data to a file on the mounted removable device.
I am finding that above a certain data rate (around 750kbyte/sec) I start to see the userland video-writing app stalling for maybe half a second, about every 5 seconds. This is enough to cause the kernel driver to run out of buffers - and even if I could increase the number of buffers, the video data has to be synchronised (ideally within 40ms) with other things that are going on in real time. Between these 5 second "lag spikes", the writes complete well within 40ms (as far as the app is concerned - I appreciate they're buffered by the OS)
I think this lag spike is to do with the way Linux is flushing data out to disk - I note that pdflush is designed to wake up every 5s, my understanding is that this would be what does the writing. As soon as the stall is over the userland app is able to quickly service and write the backlog of buffers (that didn't overflow).
I think the device I'm writing to has reasonable ultimate throughput: copying a 15MB file from a memory fs and waiting for sync to complete (and the usb stick's light to stop flashing) gave me a write speed of around 2.7MBytes/sec.
I'm looking for two kinds of clues:
1. How can I stop the bursty writing from stalling my app - perhaps process priorities, realtime patches, or tuning the filesystem code to write continuously rather than burstily?
2. How can I make my app(s) aware of what is going on with the filesystem in terms of write backlog and throughput to the card/stick? I have the ability to change the video bitrate in the hardware codec on the fly which would be much better than dropping frames, or imposing an artificial cap on maximum allowed bitrate.
Some more info: this is a 200MHz ARM9 currently running a Montavista 2.6.10-based kernel.

I have run into two problems with this:
1. Excel is not the default Windows application to open Excel files, therefore when Program.Start("xmlfilename.xml") is run, IE is opened and the XML file is not very readable.
2. If you use Excel to manually open the file, you receive a warning, "This is not an excel file, do you wish to continue". This is certainly not ideal.
Ideally, I would like Windows to open the file in Excel without modifying the default OS setting for opening Excel files. Office interop is a possibility, but seems like a little overkill for this application. Does anyone have any ideas to make this work?

1. Excel is not the default Windows application to open Excel files, therefore when Program.Start("xmlfilename.xml") is run, IE is opened and the XML file is not very readable.
2. If you use Excel to manually open the file, you receive a warning, "This is not an excel file, do you wish to continue". This is certainly not ideal.
Ideally, I would like Windows to open the file in Excel without modifying the default OS setting for opening Excel files. Office interop is a possibility, but seems like a little overkill for this application. Does anyone have any ideas to make this work?
The solution is in .Net/C#, but I am open to other possibilities to create a clean solution.

Can anyone share their experiences with similar projects? Here are my requirements:
- Source must be plain text files in some markup language. (I want to be able to use version control, arbitrarly choose my editor, etc.)
- Must compile or build to produce pretty PDF output (on par with [LaTeX][1]) **and** HTML
- Include custom HTML/JavaScript macros in the HTML edition. For example, I want an "open this in my workspace" link on each sample code block in the HTML edition of the book but not the PDF edition. I might also want to include links to create/edit a forum thread at the bottom of each section in the HTML, including text like "There are (x) comments about this section in the Forum." (Clearly this will involve some web server-side code.)
So far it looks like my best bet is LaTeX source, pdflatex output for PDF, and some custom hacking of [latex2html][2] to produce the HTML output I want. My past experience with LaTeX tells me it's very powerful but can sometimes be klunky and awkward.
[lout][3] looks very appealing but doesn't seem to have very good built-in or third-party support for HTML.
And the last option I was thinking of would be to write the book in a non-presentation format such as [Zim][4] Desktop Wiki (my favorite outliner/note taker app) and write scripts to translate this source to HTML and to lout.
Do any of these ideas sound particularly good or particularly idiotic? Who has built a technical book and targeted more than one output format?

Individual checkins are completed to the satisfaction of the developer doing the change (including tests where possible) but sometimes the direction of work changes slightly and previous commits need to be reverted and done another way. Or, stub code is filled out in later commits.
When it comes time for code review, there's a sequence of commits all tagged with the same bug tracking id number. It's easy to get a list of such changes. When a reviewer looks through the changes one by one, sometimes there will be a commit A that is undone or modified by a later commit B as part of the same review. This can make reviewing more difficult.
If only one developer was working on the file for the duration of the change, then it's easy to do a diff between the original state of the file and the final state of the file. The problem arises when another developer happens to have made unrelated changes in the same file, or even in the same functions.
How do you handle this situation? Are there tools that, given a sequence of patches to a file, can give the moral equivalent of a diff between the first and last versions, but only including a subset of those patches?
Come to think of it, I could create a temporary branch in git starting from before the first related change, and cherry-pick the changes relevant to the review. Hopefully there won't be too many conflicts that need to be resolved (and if there are, then the whole lot should be reviewed at once anyway).

I have a user object, we'll call it User, which has a property called IsAdministrator. The value for IsAdministrator is evaluated via another class that checks the User's security permissions, and returns either true or false based on those permissions. I'm trying to mock this User class, and fake the return value for IsAdministrator in order to isolate some Unit Tests.
This is what I'm doing so far:
public void CreateSomethingIfUserHasAdminPermissions()
{
User user = _mocks.StrictMock<User>();
SetupResult.For(user.IsAdministrator).Return(true);
// do something with my User object
}
Now, I'm expecting that Rhino is going to 'fake' the call to the property getter, and just return true to me. Is this incorrect? Currently I'm getting an exception because of dependencies in the IsAdministrator property.
Can someone explain how I can achieve my goal here?

1. It's a commercial library, while the plugin will be distributed freely. Also, most people won't need it and we don't want to confuse users.
2. There are currently at least two versions of the library in use and we don't want to build two different versions of the plugin. The interface is compatible, so we can ship just one version of the plugin.
The plugin is for an Eclipse-based development environment and the purpose is to provide our library's functionality within that environment. The library itself depends on other free components, which I can bundle with it without a problem.
Since I don't know if I'm allowed to say exactly which library it is, but I must keep this unambiguous, let's call the library "L" and the plugin I'm trying to develop "P".
I'm using the bnd tool for this and so far I've tried both packaging L as a standalone plugin, and as a plugin fragment.
As a standalone plugin, it was accepted by the host eclipse environment and I could list it as a dependency of P and successfully build that. However, at runtime the P plugin didn't see resources from the L library on its classpath. Mainly those in META-INF/services are needed.
Next, I tried packaging L as a plugin fragment for P. I hoped this would work, since the specs say, that a fragment's classpath is merged with its host plugin's. This didn't work, because I couldn't use the classes from L as build dependencies of P - putting L in eclipse's plugins directory didn't result in it being recognised as an installed plugin.
So I'm stuck. I need L's jars as part of P's runtime and build classpath, while at the same time having them in a separate plugin.

I expect the 16 system colors to change. They are obviously configurable. For that reason, I attempted to use the 256-color palette to construct a VIM color scheme that would be the same regardless of the terminal's 16 (configurable) system color palette.
I used only colors from the 256 color palette for everything, including background. However, I noticed that if I open terminals with different background and text colors specified for the terminals, the VIM color schemes appear quite different in the two terminals.
I do not see similar behavior on Ubuntu even when the terminals have different background, foreground, AND system color palettes.
I will happily accept an answer that explains why this happens.
I will be ecstatic if someone can tell me a way around this beyond setting up a specific terminal for each set of color settings I want to use. | vim | terminal | null | null | null | null | open | Why does the 256-color palette change in terminal VIM on OS X?

I expect the 16 system colors to change. They are obviously configurable. For that reason, I attempted to use the 256-color palette to construct a VIM color scheme that would be the same regardless of the terminal's 16 (configurable) system color palette.
I used only colors from the 256 color palette for everything, including background. However, I noticed that if I open terminals with different background and text colors specified for the terminals, the VIM color schemes appear quite different in the two terminals.
I do not see similar behavior on Ubuntu even when the terminals have different background, foreground, AND system color palettes.
I will happily accept an answer that explains why this happens.
I will be ecstatic if someone can tell me a way around this beyond setting up a specific terminal for each set of color settings I want to use. | 0 |

I played around (struggled) with it for a while and got it to a very basic level but then was too annoyed by the limitations I was encountering (which may well have been limitations of my knowledge) and when I read a blog suggesting to ditch XSLT and just write your own XML-to-whatever parser in your language of choice, I eagerly jumped onto that and it's worked out brilliantly.
I'm still working on it to this day (_I'm actually supposed to be working on it right now, instead of playing on SO_), and I am seeing more and more things which make me think that the decision to ditch XSLT was a good one.
I know that XSLT has its place, in that it is an accepted standard, and that if everyone is writing their own interpreters, 90% of them will end up on DailyWTF. But given that it is a declarative style language instead of the procedural style which most programmers are familiar with, for someone embarking on a project such as my own, **would you recommend they go down the path that I did, or stick it out with XSLT**? | xslt | xml | null | null | null | 01/26/2012 16:30:00 | not constructive | Is XSLT worth it?
