My plan is to include content such as my resume, any projects that I have done on my own and links to open source projects that I have contributed to, and so on. However, I'm not sure which approach would be better from a perspective of "advertising" myself, since that what this site does, especially since I am a software developer.
Should I use an out-of-the-box system and extend it as needed, with available modules and custom modules where needed or should I custom build a site and all of its features as I need them? Does a custom site look better in the eyes of a potential employer who might visit my site? | website | content-management-system | personal-website | null | null | null | open | Personal Website Construction

Mostly I've written database driven applications, but occasionally, even those require some file io. Since I do it so rarely, I end up googling around for quite some time to figure out the exact incantation that Java requires to read a file into a byte[], char[], String or whatever I need at the time.
For a 'once and for all' list, I'd like to see all of the usual ways to get data from a file into Java, or vice versa. There will be a fair bit of overlap, but the point is to define all of the subtle different variants that are out there.
For example:
1. Read/Write a text file from/to a single String.
2. Read a text file line by line.
3. Read/Write a binary file from/to a single byte[].
4. Read a binary file into a byte[] of size x, one chunk at a time.
The goal is to show concise ways to do each of these. Feel free to suggest more IO tasks that are somewhat common and I have neglected to mention. | java | file-io | null | null | null | null | open | Java File IO Compendium

The justification for this was, that if you left the code as is, an exception would be raised (NullReferenceExcpetion) when you attempted to use the parameter. The alternative is explicitly checking for null and throwing an ArgumentNullException.
This gives the same effect but you're right extra lines of code. You wouldn't ever write code to handle either exception and thus you'd really encounter these at runtime when testing and then fix the code to stop the exceptions from happening in the first place.
I'm not saying I agree with the guidance but it did make sense when I first read it and still makes sense now.
I generally check for null parameters on non-private methods only but leave private methods to throw a NullReferenceException.

In my situation I receive an Bitmap for a ListView item via the network (Which isn't cheap in terms of processor or network traffic). The user will likely load a few items into the list and then juggle between a "detailed" view of each item. In this situation the following code makes sense, the ***second*** load of a "detailed" view of an item will results in an instant loading of the bitmap:
private Bitmap bitmap = null;
public Bitmap getBitmap(int id) {
if(bitmap == null) bitmap = expensiveNetworkOperationToGetBitmap(id);
return bitmap;
}
(please ignore thread blocking concerns)
However, it's perfectly possible the user will make life difficult and look through many items. Each one slowly taking up a slice of memory, eventually going over budget and crashing the app.
Without knowing the likely behaviour of a user who is making life difficult, is it possible to "Cache until memory is getting scarce" and then start destroying the old images as you add new ones? See below for sample code:
private HashMap<Integer, Bitmap> bitmaps = new HashMap<Integer, Bitmap>();
public Bitmap getBitmap(int id) {
Bitmap bitmap;
if(!bitmaps.contains(id)) {
if(// Bitmap budget close to being exeeded?) {
bitmaps.keyValues().get(0).recycle();
bitmaps.remove(bitmaps.keyValues().get(0));
}
bitmap = expensiveNetworkOperationToGetBitmap(id);
bitmaps.put(id, bitmap);
else {
bitmap = bitmaps.get(id);
}
return bitmap;
}
(Once more, please ignore concerns for the inefficency of popping the first Bitmap from the HashMap.)
So, is it possible to check the current VM budget available and is the above method safe?
*NB. There are a lot of questions regarding the vague "Caching Bitmap's In Android", They usually stem from using Bitmaps in ListViews and "Exceeding VM Budget" errors. Invariably these are answered by people saying "Load less / smaller bitmaps" or "Use lazy loading".

There are five tasks, and each one requires separate C file compiled and ran. As I have to include some additional libraries while using gcc I'd like to just type `make ZAD=first second` and have first.c and second.c compiled. The problem is I don't know how to iterate properly through the `ZAD` list in the makefile. I can separate the tasks in `for` loop, but I can't force a newline char in this loop. This example will explain better (the following is my makefile):
ZAD = first second
main: $(foreach dir, $(ZAD), $(dir).o)
$(foreach dir, $(ZAD), gcc $(dir).o -lgsl -lgslcblas -lm -o $(dir))
$(foreach dir, $(ZAD), rm $(dir).o)
first.o: first.c
gcc -Wall -c first.c
second.o: second.c
gcc -Wall -c second.c
Here's what I get when for instance I try to compile solely second.c:
wojtasskorcz@wojtek-laptop:~/mownit/lab1dom$ make ZAD=second
gcc -Wall -c second.c
gcc second.o -lgsl -lgslcblas -lm -o second
rm second.o
And everything's fine, but when i try to compile first.c and second.c at one go here's what happens:
wojtasskorcz@wojtek-laptop:~/mownit/lab1dom$ make ZAD='first second'
gcc first.o -lgsl -lgslcblas -lm -o first gcc second.o -lgsl -lgslcblas -lm -o second
gcc: error: gcc: No such file or directory
make: *** [main] Error 1
I came to the conclusion, that it's because in the second `foreach` in makefile there's no newline character. But I don't have a clue how to insert it there. Or maybe there's another approach to this problem?

I have noticed with programming languages and environments that they tend to follow a curve that is in some ways similar to natural selection and evolution in species. Simple things tend to stay simple and have longevity (both bacteria and C have been around forever in basically the same form, and aren't going away anytime soon), whereas complicated things change radically, become useful, but then keep changing, change too much and then die. Or maybe they don't change enough and die. Complicated things tend to have narrow niches.

The new AJAX stuff is nice (I think that's ASP.NET 3.5?), but I can do AJAXy things in a million different ways using the current environment.

Profiling a particular app with the RPM showed me that the total usage of all the caches only manages to get to about 12mb and then slowly shrinks as (I assume) something unmanaged starts to claim more memory.
The memory slider in System also shows that the device is very short on memory. If I kill the process the slider shows all the memory coming back. So it must (?) be this managed process that is swallowing the memory.
Is there any simple(ish?) fashion how one can track unmanaged memory usage in some way that might enable me to match it up with the corresponding P/Invoke calls?

My personal preference would be to utilize a prefix for instance variables both for clarity within functions and to prevent shadowing of function parameters. However I'm a fan of properties which rules out prefixes (unless you also prefix your property names, which doesn't work too well and looks daft). Similarly I could use the "self.variable" convention, but only if I make EVERYTHING a property.

s = StringIO.new
s << 'foo'
s << 'bar'
s.tos # I mean with an underscore, but Markdown hates that
# => should be "foo\nbar"
# => really is ''`
Ruby really needs a StringBuffer just like the one Java has. StringBuffers serve two important purposes. First, they let you test the output half of what Ruby's StringIO does. Second, they are useful for building up long strings from small parts -- something that Joel reminds us over and over again is otherwise very very slow.
Is there a good replacement?

In IIS 7.0, the same config settings do not pass the credentials, and the DB gets hit with NT AUTHORITY\ANONYMOUS.
Is there something I'm missing? I've turned ANONYMOUS access off in my IIS 7.0 website, but I can't get the thing to work.
These are the settings that I'm using on both IIS 6.0 and 7.0:
> authentication mode="Windows"
> identity impersonate="true"
What changed from 6.0 to 7.0? | 0 |

So, after googling for the answer and finding only a little bit of information on it I came up with the following and decided to post it here now that I'm in the beta.
The 'click sound' in question is actually a system wide preference, so I only want it to be disabled when my application has focus and then re-enable when the application closes/loses focus.
using System;
using Microsoft.Win32;
namespace HowTo
{
class WebClickSound
{
/// <summary>
/// Enables or disables the web browser navigating click sound.
/// </summary>
public static bool Enabled
{
get
{
RegistryKey key = Registry.CurrentUser.OpenSubKey(@"AppEvents\Schemes\Apps\Explorer\Navigating\.Current");
string keyValue = (string)key.GetValue(null);
return String.IsNullOrEmpty(keyValue) == false && keyValue != "\"\"";
}
set
{
string keyValue;
if (value)
{
keyValue = "%SystemRoot%\\Media\\";
if (Environment.OSVersion.Version.Major == 5 && Environment.OSVersion.Version.Minor > 0)
{
// XP
keyValue += "Windows XP Start.wav";
}
else if (Environment.OSVersion.Version.Major == 6)
{
// Vista
keyValue += "Windows Navigation Start.wav";
}
else
{
// Don't know the file name so I won't be able to re-enable it
return;
}
}
else
{
keyValue = "\"\"";
}
// Open and set the key that points to the file
RegistryKey key = Registry.CurrentUser.OpenSubKey(@"AppEvents\Schemes\Apps\Explorer\Navigating\.Current", true);
key.SetValue(null, keyValue, RegistryValueKind.ExpandString);
isEnabled = value;
}
}
}
}
Then in the main form we use the above code in these 3 events:
* Activated
* Deactivated
* FormClosing
private void Form1_Activated(object sender, EventArgs e)
{
// Disable the sound when the program has focus
WebClickSound.Enabled = false;
}
private void Form1_Deactivate(object sender, EventArgs e)
{
// Enable the sound when the program is out of focus
WebClickSound.Enabled = true;
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
// Enable the sound on app exit
WebClickSound.Enabled = true;
}
The one problem I see currently is if the program crashes they won't have the click sound until they re-launch my application, but they wouldn't know to do that.

Unfortunately, that doesn't look to be so simple - The writer has no way to take an event type and a parser object, only methods like writeAttribute and writeStartElement.

Unfortunately, that doesn't look to be so simple - The writer has no way to take an event type and a parser object, only methods like writeAttribute and writeStartElement. Obviously I could write a big switch statement with a case for every possible type of element which can occur in an XML document, and just write it back out again, but it seems like a lot of trouble for something which seems like it should be simple.
Is there something I'm missing that makes it easy to write out a very similar XML document to the one you read in with StAX? | 0 |

This seems fine, except the remoting call still takes up a thread from the thread pool.
Is this the same thread pool as the asp.net worker threads?

Part of this refactoring, has been to move code that's common to two of my models to a module that I can include where I need it.
So far, so good. Looks like it's going to work out, but I've just hit a problem that I'm not sure how to get around. The module (which I've called sendable), is just going to be the code that handles faxing, e-mailing, or printing a PDF of the document. So, for example, I have a purchase order, and I have Internal Sales Orders (imaginatively abbreviated to ISO).
The problem I've struck, is that I want some variables initialised (initialized for people who don't spell correctly :P ) after the object is loaded, so I've been using the **after_initialize** hook. No problem... until I start adding some more mixins.
The problem I have, is that I can have an **`after_initialize`** in any one of my mixins, so I need to include a **super** call at the start to make sure the other mixin **`after_initialize`** calls get called. Which is great, until I end up calling super and I get an error because there is no super to call.
Here's a little example, in case I haven't been confusing enough:
class Iso < ActiveRecord::Base
include Shared::TracksSerialNumberExtension
include Shared::OrderLines
extend Shared::Filtered
include Sendable::Model
validates_presence_of :customer
validates_associated :lines
owned_by :customer
order_lines :despatched # Mixin
tracks_serial_numbers :items # Mixin
sendable :customer # Mixin
attr_accessor :address
def initialize( params = nil )
super
self.created_at ||= Time.now.to_date
end
end
So, if each one of the mixins have an after_initialize call, with a **super** call, how can I stop that last **super** call from raising the error?

The AzMan store is hosted in ADAM on another computer in the same domain. Other computers and users do not have this problem. The user making the call have read access to both ADAM and the AzMan store. The computer running the WinForms app and the running ADAM are both on Windows XP SP2.
I've had access problems with AzMan before that I've resolved but this was a new one... What am I missing? | 0 |
