It just occurred to me that the following might be possible, and not only is it possible, Eclipse already does it.

I’ve seen this quite a few times, and I feel it’s worth mentioning, as it perhaps isn’t obvious.

It’s modern practice in web applications to augment text fields with suggestions while one types.

Searching for this topic on the web led to various libraries, all of which were no doubt very powerful, all of which were extremely large and difficult to use if one didn’t know how.

It’s a common enough problem, you want to find out if a date is in a particular month, or you want to know how many days there are left in the current month, and so on.

The MySQL curtime function has (at least) the following issues: The function returns the current time as a number i.e. the time quarter past 8 would be returned from the function as the number 201500.

Last night, I was listening to music, about to go to bed, totally relaxed, and then suddenly smelt that something was burning.

PHP is a weird language.

Quotes in CSV files are a classic case of a solution to a problem, which in fact does nothing to solve the problem, but is a problem of its own.

There is a great debate in C-style languages about the position of the asterisk and the space when declaring pointers: MyType *x; // Original C style MyType* x; // The other style I was reminded of this when attending an Objective-C training course recent…

I’ve just got back from a 4-day course on working in teams (“Erfolgreich Zusammenarbeit im Team” by Coverdale for my employer s IT Solutions).

I had the situation recently where I needed a “button”; when the user clicks the button, then: An "svn up" should occur, to update some XML config files + data files (CSV) If the config files or CSV files have errors, the operation should be aborted and an

Sometimes it’s valid to have tables that reference one another.

A few weeks ago I got really into stackoverflow.com, the question/answer site for programming: But now I’ve got a bit bored of it.

I have been working self-employed for s IT Solutions since 1 March 2010; from 1 September I’m salaried there.

In Javadoc there is an @author tag so you can specify who originally wrote the class, method, etc., being documented. /**  * This represents a user of the system as stored in Oracle

Java supports checked exceptions.

I tried to use my company laptop outside of the office for the first time.

If you allow users of your website to upload data (e.g. images), and you display this data to other users, you need to open the file on the server to examine it and check that it really is what it should be (e.g. an image).

A server filesystem can store millions of files in one directory.

The UNIX program “mail”, not the mail client one would use by choice under most circumstances.

I was reading an article about the RISC OS operating system and the fact that it doesn't support multiple CPU cores.

Computers, if they are addressing the user, should address the user as "you", not as "me".

I tried to write a program using Java; it all seemed to be going well but then I hit a ridiculous limit.

Something is going wrong in my life.

Before everyone gets too excited about golang, let’s not forget it lacks: Exceptions Assertions Inheritance Generic types Generics are necessary to express concepts like List<List<MyType>>.

There is the following design error in Java (at least in Servlets): A server may serve multiple applications; each application may use different libraries or even different versions of the same library, “side by side”.

My colleagues have just released a feature on www.easyname.eu where I work – it’s an automated domain-registration and web-hosting service – that you can “ssh” (log in) to your easyname filespace account.

When developing PHP, a front-end PHP file will include other files: classes, utilities, etc.

It is literally 23:19 on a Sunday and I’ve been working through the weekend to get a release out of some software I’m working on.

The MySQL LOCK TABLES (and UNLOCK TABLES) command has a nasty side-effect.

Java’s slogan was “write once, run anywhere”.

Thanks the the internet archive I found one of the first (or one of the only?)

Windows, Linux and OS X offer the ability to view the utilization of each CPU/core in the system.

I see why people get a bit upset about the privacy aspects of Google Streetview!

Today and tomorrow I am at an Ask Tom Live Seminar in Prague.

Cool, just discovered: if you’re using the (UNIX command-line program) “less” to view a file, you can hit the “v” character to open the file in “vi”!
