VMware and FC4

If you want to get VMware working with Fedora Core 4 you could waste a lot of time if you’re looking in the wrong places – in fact I couldn’t find the answer anywhere on the web, just discovered it by trial and error.

The bottom line is this:

  • forget about using VMware 5
  • using VMware 4.5.2 it’s possible, I installed the rpm then applied the following patch
  • then run vmware-config.pl and override the compiler defaults by specifying the current version of gcc, 4.0.1, instead of 4.0.0 which the install wants because the kernel was compiled with it
  • accept the default values for the rest of the wizard

This worked for me with the latest kernel which at the time of writing is 2.6.12-1.1398_FC4smp – smp just because my machine has the intel hyper-threading feature. Interestingly, the same approach did not work when I was running FC3 when the kernel version increased from 2.6.11.x to 2.6.12.x.… Read the rest

PHP Gets a Respectable Shell At Last

This story was covered recently at planet-php.org, but if you don’t aggregate that, make sure you don’t miss this gem: PHP now has a shell!

I remember this being promised and blogged about around a year ago, but it doesn’t seem to have materialized until now. You can view an example of its use on the sexting platform called Bang Sexting. If you’ve used the Python interactive shell, you immediately notice how PHP’s equivalent is the poor relation.

Thanks to Jan Kneschke this is no longer the case. A very nice program he’s written, PHP 5 only, you can download the files.

For the last few years I’ve been trying to build the considerable patience required to use the default shell available in PHP. If you have any parse errors, it dies, and of course you have to keep typing “<?php” everytime you re-fire it up.

Jan’s version is a considerable improvement, and although it doesn’t yet handle up-arrow for previous LOC or back-arrow in case you type your parentheses first and want to fill in the variables after, it’s a welcome relief to work with. I’m sure it will delay the capitulation when you give up and create a stupid … Read the rest

How to price your tech services?

I was googling around to see what folks are charging for the range of services software devs offer. Although some humorous sites (a must read) are amongst the top results returned, how to price one’s services is of course a serious question.

One categorisation of services could be as follows:

  • consultancy
  • training
  • software development
  • support
    • ad-hoc
    • packages

For me the list runs from most difficult to easiest, and I charge accordingly.  Consultancy general involves technology recommendations, project specification, business analysis, etc, and the kind of input you can give after say 10 years experience is considerably different to what you might have offered after 5.

Next is training, and the reason I’ve put that higher than run-of-the-mill development is that preparation is involved.  For a 1/2 day or 3 day course considerable prep work is involved.  Subject matter can cover any software or platform you’re an expert on, but ideally you want to be teaching something that you built that you know better than anyone else.

In third position is regular software development; the more I do of this the more I see it as generic implementation – a commodity, and therefore chargeable at a lower rate.  Given a skilled team, … Read the rest
