Google announced the chromebook yesterday (11 May 2011). While this is surely a nice thing, I have no clue whether it was interesting to buy one for a (non-javascript)-programmer.
What do you think? Will there be, for instance, a Java IDE in the cloud? A command line, even?

Disclaimer: I'm a newcomer (this is my third day of work), and most of my teammates are more experienced than me.

I am currently a C# developer with a pretty shaky understanding of threading.
Both of these links have been suggested in other posts:

Should I go back to basics and maybe look at some computer science texts on the subject?

I'm a consultant at one company. There is another consultant who is a year older than me and has been here 3 months longer than I have, and a full time developer.
The full-time developer is great. My concern is that I see the consultant making absolutely terrible design decisions. For example, M:M relationships are ... |
Off the clock I'm going to try and come up with a strategy for version control for my company; we currently use SVN but there's no structure to it - we basically only have a trunk and only commit to that.

I have taken over development of a JSP/Struts application. Right now it's a bit of a mess, and I'm finding the JSP pages with Struts tags to be insanely verbose. Has anyone migrated a Struts application to Groovy/Grails? Can it be done incrementally, page by page?

I am doing out some flow charts and am wondering if I am approaching this correctly. In essence, I have several method calls and I am flowcharting each separately. However, several of these methods make a method call for some info and then continue. See this example:

I really dislike regular expressions, each time I come back to it I seem to have to relearn it. It's also incredibly hard to maintain, modify and at a glance understand what it is doing.

Often, in libraries especially, packages contains classes that are organized around a single concept. Examples: xml, sql, user, config, db. I think we all feel pretty naturally that these packages are correct in the singular.

I manage an open source PHP/MySQL web application used by a few K-12 schools and some colleges. I'm also the project's only developer.

I'm looking at architecting a new solution that is very modular by nature and would like to create a structure that supports that design to allow for easy future expansion, clear separation of concerns, licensing by module, etc. Most of what I've found on the web about modular or composite applications are UI-centric,... |
After reading Should package names be singular or plural? it occurred to me that I've never seen a proper debate covering one of my pet peeves: naming implementations of interfaces.

I'm writing a small application that will reset the entire “environment” consisting of various machines and applications.

Is there any reason to build constraints between tables (inside SQLserver) nowadays? If so, when? Most applications in my area are built on object principles and tables are joined on demand.

Many applications include 'static data': data that doesn't really change during the lifetime of the application. For example, you might have a list of Sales Areas that is likely to be a fixed list for the foreseeable future.
It isn't uncommon to find this static data in a database table (often because you want to refer... |

I have two issues with Scrum in embedded systems. First, there are many tasks to do, especially in the early stages, which are not demonstrable. We started with a development board, no OS, no display, no serial communication, etc. We didn't have our display for six sprints.

In my current company, in all software projects I've been in, there's usually a phase at the end of a project that eats some good amount of time and is dedicated to polishing new features so that they're ready for launch.
