The same guy also has [a great set of graphical cheat sheets][2] that teach the basics a few bits at a time.
I'm convinced.
I've been convinced for the past 2 years in fact. But I still really haven't gotten around to force myself to learn vi as my primary editor, the learning curve is just too high. When I get down to work, acceptable but immediate productivity (using my current editor) has so far won over tremendous productivity farther down the line (using vi).
Does anybody have any good tips to help get past the learning curve? It can be straight out tips, some other tutorial or article, whatever.

My application is generating config files for network devices (routers, load balancers, firewalls, etc.). My plan is to template the config files, using embedded ruby (via either eruby or erb) within the source files to do things like iteratively generate all the interface config blocks for a router (these blocks are all very similar, differing only in a label and an IP address). For example, I might have a config template file like this:
hostname sample-router
<%=
r = String.new;
[
["GigabitEthernet1/1", "10.5.16.1"],
["GigabitEthernet1/2", "10.5.17.1"],
["GigabitEthernet1/3", "10.5.18.1"]
].each { |tuple|
r << "interface #{tuple[0]}\n"
r << " ip address #{tuple[1]} netmask 255.255.255.0\n"
}
r.chomp
%>
logging 10.5.16.26
which, when run through an embedded ruby interpreter (either erb or eruby), produces the following output:
hostname sample-router
interface GigabitEthernet1/1
ip address 10.5.16.1 netmask 255.255.255.0

A bit like how you're able to see the values in the CallStack when in the VS debugger. My approach has concentrated on using the StackFrame class and then to reflect over a ParamaterInfo array.

Does anyone have an approach for achieving this?

StackFrame[] frames = st.GetFrames();
foreach (StackFrame frame in frames)
{

sb.AppendFormat("{0} - {1}",method.DeclaringType, method.Name);

If you look at the onSuccess part of the ajax call, you'll see that at that point $('content').innerHTML has stuff in it.
However when I check $('content').innerHTML right after the ajax call, it appears to be empty.
This has to be some fundamental misunderstanding on my part. Anyone care to explain it to me?

I've been rather interested in how, using the .NET platform, one can write a compiler for a language that already has a compiler (like C#) that will generate separate output from the original compiler while allowing the original compiler to generate output for the same source during the same build operation, all the while referencing/using the output of the other compiler as well.
I'm not entirely sure I even understand the process well enough to ask the question with the right details, but this is the way I currently see the process, as per diagrams in the Script# docs.

Does anyone know of a good open source plugin for database querying and exploring within Eclipse?
The active Database Exploring plugin within Eclipse is really geared around being associated with a Java project. While I am just trying to run ad-hoc queries and explore the schema. I am effectively looking for a just a common, quick querying tool without the overhead of having to create a code project. I have found a couple open source database plugins for Eclipse but these have not seen active development in over a year.
Any suggestions? | 4 |

Some languages, like JavaScript, adapted basic features like garbage collection and lexical closures, but all the stuff that might actually change how you write programs on a large scale, like powerful macros, the code-as-data thing and custom control structures, only seems to propagate within other functional languages, none of which are practical to use for non-trivial projects.
The functional programming community also came up with a lot of other interesting ideas (apart from functional programming itself), like referential transparency, generalised case-expressions (ie, pattern-matching, not crippled like C/C# switches) and curried functions, which seem obviously useful in regular programming and should be easy to integrate with existing programming practice, but for some reason seem to be stuck in the academic world forever.
Why do these features have such a hard time getting adopted?

I tend to feel that there is a definite relationship between application quality, reliability and speed of delivery.
I take Stackoverflow as a good example. I love the quality of the site, (and I think it's going to be the next big thing on the Inter-tubes), but I found it surprising (as did Jeff when he mentioned it on the podcast) that some people thought that they could code this whole site in a week or two. I have no doubt how hard Jeff and his team worked to develop this site into what it is today. And I don't blame them one bit for holding back the release date a couple weeks.
I find that these views about development permeate the developer landscape, thus leading to lower quality applications (ie. bug ridden, despite delivering on time). They also seem to undermine efforts to make sure that at least a certain level of quality is built into the code.

We would like to make it possible to import custom initial settings as part of the installation. The use case for this is if a company has 100 machines they want to install the software on, and they should all have a reference to the intranet web service in question, this should not need to be set up manually on all the machines.
We are currently using a VS2008 setup project to generate the install package.
Our idea so far has been to enable the installer to make a custom initial .config file with the information (from a template), and then put that in place instead of the default one that the setup project installs.
However, I can't see a way to do this other than these few:
1. Hardcode the executable name into a custom installer action (deriving from System.Configuration.Install.Installer), in order to use the ConfigurationManager class to determine the .config file path. This would require manual changes to the installer if the executable name changes.
2. Roll our own configuration classes or file/folder hierarchy to store the settings. This would basically bar us from the advantages of the isolation mechanism (which is also the obstacle here) that .NET provides, if I understand correctly.
Does anyone know of any alternatives, or of ways to make the above two palatable?

The issue I'm having is that the page should work using the form's initial values (unbound), but I can't access the cleaned_data field unless I call is_valid(). But is_valid() always fails on unbound forms.
It seems like Django's forms were designed with the use case of editing data such that an unbound form isn't really useful for anything other than displaying HTML.
For example, if I have:
if request.method == 'GET':
form = MyForm()
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
is_valid() will fail if this is a GET (since it's unbound), and if I do:
if request.method == 'GET':
form = MyForm()
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
the first call to do_query triggers exceptions on form.cleaned_data, which is not a valid field because is_valid() has not been called. It seems like I have to do something like:
if request.method == 'GET':
form = MyForm()
do_query(form['start_date'].field.initial, form['end_date'].field.initial)
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
that is, there isn't a common interface for retrieving the form's values between a bound form and an unbound one.
Does anyone see a cleaner way to do this?

is_valid() will fail if this is a GET (since it's unbound), and if I do:
if request.method == 'GET':
form = MyForm()
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
the first call to do_query triggers exceptions on form.cleaned_data, which is not a valid field because is_valid() has not been called. It seems like I have to do something like:
if request.method == 'GET':
form = MyForm()
do_query(form['start_date'].field.initial, form['end_date'].field.initial)
else:
form = MyForm(request.method.POST)
if form.is_valid():
do_query(form.cleaned_data['start_date'], form.cleaned_data['end_date'])
that is, there isn't a common interface for retrieving the form's values between a bound form and an unbound one.
Does anyone see a cleaner way to do this?
