Just a short note to say that I truly love the web hosts 1and1. That’s who my server is hosted with, and who is responsible for hosting all of the sites I have.

They have great dedicated server packages that are super fast, with loads of bandwidth. I actually run visualchat.co.uk on on of their dedicated servers, which has ample bandwidth for all the audio and video of the webcam chat sessions.

In short,

• the servers are fast,
• they got great control panels,
• the support is actually really good, both written, and on the phone,
• the bandwidth is phenomenal,
• you get free ftp backup with each dedicated server,
• they never go down.

They really are great – I strongly recommend them… However, I’m not writing because of that – I’m writing to let you know that they have exceeded my expectations again:

In September 2007 I took up a new server package, a beefed up dedicated server, that came with 3 months free contract, then 18 months minimum term. Now, I was intending to migrate my existing dedicated server (contract expired) to the new server.

However, I started working for Adobe, and was so busy that I never got a chance to move the server, and therefore ended up paying for both dedicated servers. Now 1and1 get a few bad reviews for locking people into contracts, but I have to say – they were great with me – I called them, explained what had happened, and they simply asked me to fax them the details.

The server is now cancelled: Including the 18 month contract! Yep! they just let me back out of it, by being reasonable and human about it all – so next time someone tells you that they are monsters, and hold people in to contracts, I suggest you ask them how they spoke to their staff, and how they treated them – I know other people who have been rude, and they get what they give..

I don’t know any other host that would do this – I can definitely tell you 3 other hosts that wont budge at all on these matters (though I don’t want to name them)...

BTW, I’m not an affiliate – I haven’t joined their program, so I’m genuinely objective – check them out if you want dedicated servers- for any small-medium scale project (read as, don’t need a server farm and fail over), they’re great!

I passed my ACE exam,

I’m now an Adobe Certified Professional in Flex. Whoohoo!

I’m really chuffed, I scored 86%, and got 100% on the UIComponent section, which is no surprise really, as I do lots of ux work on our current project. Getting to the exam was hilarious. It was on a Sunday and we don’t have a train service on a Sunday, so I planned it precisely: cabs, bus, tube, the lot. 2 hours of travel to get to the examination only to find… I’d gone to the wrong place!!!

I couldn’t believe it, I had just 45 minutes to get to the other side of London. Fortunately, I found a mini cab office next door with a cab driver who was like something from a Jason Staham movie (think “the transporter”). This guy was super cool, and drove like a maniac. I had to use his 10 year old map of London to find the way to the proper examination centre, which made me sooo travel sick, it was unbelievable..

But we got there, and despite me being late and so sick that I had to sit down for 10 minutes, I passed! I have to say it, the exam is quite hard – you need to know a lot of stuff to pass. Here’s a pic of all the notes that I made over the last 3 weeks. If you’re gonna do this, even if you’ve been doing flex for a year or more, I really suggest reading up, for a few reasons:

• the areas covered by the exam are very diverse,
• you need precise knowledge of some controls in order to choose between bogus properties, and real properties,
• It tests you on some of the finer points of framework, such as low level event architecture and the collection and renderer interfaces,
• best of all – you learn loads by reading up.

This is my new open source project…

Flex TRAMP is a testing Runtime Actionscript Mini Parser,..

which means it allows you to interact with your running flex app, and:

• create variables,
• assign objects,
• update attributes,
• call methods
• and basically interact with your flex app.

Why?

Me and some colleagues are currently working on a flex app that takes a while to build. It’s very frustrating to do a build, then see that some variable, or object is initialised with the wrong value, and have to rebuild again..

I’m used to working with FIrebug – if something goes wrong with my js, I can modify it on the fly, and try again.

Take this example: We’ve got a part of our app that prints some info out. To get to it, you have to enter lots of registration info, and perform lots of tasks.

With FlexTRAMP, I can fire up the app, and in the command line window that appears when I click the FlexTRAMP button, I can create and initialise all of the objects I need, and call the print method, again, and again and again.. no need to go through the whole registration process. Lots of time saved, I’m more productive, and therefore happier :)

Another example – only just today – I did a few changes and made a build. I found that the currentState of one of my component’s was wrong.. This meant I had to go back and rebuild again… however, using FlexTRAMP, I could still set the state, update a few vars, and one method call later, debug a transition I had, which I found needed a slight tweak.

So you see, I didn’t end up doing a build and achieving nothing.

For anyone used to Firebug, or Microsoft’s command line processors, you will know the use of this approach. It’s not a replacement for unit tests, but a very useful tool for when you have to get hacky with some defects, or trail blazing some code.

But I thought Actionscript doesnt have eval?

Thought I’d share this with you..

If you’re using flexUnit and want to test some class or method that dispatches an asyncrhonous event, then this snippet is for you.

I’ve seen this done a few ways, but I recently discovered this neat little feature of flexUnit. If you know this already, then good for you, but if not, let me introduce you to the addAsync method.

Basically, this TestCase method acts as a proxy between you’re addEventListener call and FlexUnit, giving you a teeny bit of extra functionality on the way. The basic use is:

2. myObject.addEventListener( eventName addAsync( handlerMethod, timeOutInMillisecs ) );

It’s quite straight forward, you provide it with a handler in your TestCase, and if a matching method is not dispatched in the prescribed amount of time, the test fails. Neato.

I’m going for my Adobe Certified Exam in flex later this month. Most people wait till they pass to make it public knowledge. You’re sat next to someone for months, then one day they suddenly come out with : “yeah, I got my ace now”, or you read a blog post “I passed my ACE”.... well, balls to that! I haven’t passed mine yet… I might fail and look like an utter cock in the process! However, at least this way…

• More pressure on me to pass,
• I’m being straight with my friends and colleagues, and not just suddenly being like “oh, yeah I was just walking to work the other day and wow! there was this exam hall right there and they just happened to be doing the ACE exam, which I’ve never mentioned to you ever before, and I just happened to be on the register, and just happened to go in and pass, so yeah, yesterday I wasn’t an ACE, but now I am..”
• At least I can blog about the learning process with some gusto… I wont elaborate, but what man ever takes his missus out to dinner again, once he’s had desert…

I’ve so far found that Lynda.com is great to do a refresher course of what you know – and it’s also really good for learning some new stuff too (despite using fms and flashcom, I’ve not had much exposure to FDS or LCDS). I’d heartily recommend going through their excellent Flex videos. I also recommend reading “flex 2 training from the source” and cribbing on “UML demystified” or another similar title.

There are a couple more things you can do as well. This one chap has made ATTest which is an excellent tool for doing mock exams in Flex – it comes with 3 mini tests and 3 exams, and comes for the bargain price of : £20 ($39)... I heartily recommend it.

I’ve been particularly working with E4X and LCDS, which are certainly my weakest areas. My test is on the 24th – so we’ll just have to see how it goes. I’m hoping that I pass though, not least of all because everyone knows I’m sitting the test!

I’ll keep this blog up to date with my progress and let you know any cool stuff I find.

WISH ME LUCK :D !!

Failing that, give me some good advice!! Anyone else done it? Got any suggestions.. wow – look : there’s a comments form below, just for you!

It’s been a while since I’ve written anything on this blog. There I was, getting my ruby on rails funk on, getting all RIA, with my javascript and flex, and planning a startup or 2 with my good friend Jon Baker, when life suddenly decided it had different ideas.

Since then I’ve been working for Adobe consulting, the last 5 months, as a senior consultant with Flex 2. It kinda happened by accident, but boy am I glad it did :).

I’ve been using Flex 2 for more than a year now, and flash for a long time before, but I hadn’t quite fallen for it, if I’m honest. I was still loving all of my Ruby on Rails goodness, and getting quite agile (no pun intended) with js and programming the DOM.

I was using Flex in a very specific way: Writing portal’s and services in Ruby on Rails and mysql, and having the actual “rich” bit (the app), in Flex.

I thought I’d take the Adobe gig for a bit, then get back to the world of freelance Ruby on Rails, and making sites by my lonesome… but that hasn’t happened. I’ve actually totally fallen for using Flex now: No more messing around with cross browser issues, no javascript worries, no DOM Hassle, and the framework is fantastic : Powerful, and very flexible.

It really is what I like to do – I love ECMA Script based languages, and the frustration of js in the browser for me has always been the DOM, and not the js. With flex I get to do the programming I love most. I still get to do some js, and xhtml, and backend stuff like Java and Tomcat and all that (I’m lucky enough to be using Live Cycle Data Services on a project), so I’m still keeping my finger in lots of pies here, and as such keeping myself interested, and always raising my game..

As for contracting – I gotta say it : I prefer working as an on-site consultant, to freelancing at home. Sure, I gotta wear the trousers and shirt, I gotta be on site pretty much in core hours, I’m not my own boss, but man.. it’s great! I like having to wear smart clothes (I can rip them off when I get home and forget about work), I like being there in core hours (means I can’t procrastonate, or waste time), I like being told what to do – I mean, I still end up getting responsibility for stuff (don’t we all?), but at least it’s not ALL on my shoulders.

Biggest of all though, is that I’m not alone at home, with just IRC. No, let me rephrase that, I’ve got good company at work.. In fact, I’ve got really good company – great colleagues who are not only really really technically savvy and know their shit, but who are a great crack – real great blokes – everyday I feel so lucky to go to work, not only with such great technology, but also with such ( professionally and personally ) wonderful people.

So it’s been a real time of change – changing technology (going toward flex, LCDS and Java from Ruby on Rails and AJAX), changing philosophies and changing fortunes. Its meant I’ve been too busy to update life on rails, but I think now I’m ready to write up some more articles, which I hope others will find useful.

Have I gone all Zed Shaw, and turned my back on rails? Shit, no! I still think Rails rocks, but it’s just not where I want to be at the mo. For the time being, I’ve kinda had it with all the pressure of making sites by myself (and supporting them.. yuk!).. and Rails is particularly good for that. I’m enjoying more being part of the whole, and contributing with others, to create something much better than I could make by myself.

I’m keeping the name of this blog, too: “Life on rails”, clearly a a pun on ruby on rails – but after my wild 20’s, travelling around and doing crazy shit, it’s a reminder to me, if anyone, that I’m on the rails, and for the time being, I’m on them with Flex :)

I use remote desktop for windows in x11, as it’s the best version out there – believe it or not, it’s still better and faster than the latest version micro$ft released just a few weeks back. Anyhows, one annoyance for me is that the apple menu strip, often times will overlap your windows applications, making resizing them or closing them a bit of a nuisance.

Well it turns out that you can hide the menus strip in os x on an app by app basis.

You do the following.

1. View the package contents of the application you wish to hide the menu bar for,
2. Open the file Info.plist in a good text editor,
3. Add the following to the list of keys:

<key>LSUIPresentationMode</key>
<integer>4</integer>

Bingo!

Your menu bar will now hide whenever you select the app.

I was googling about and came across this article by Daniel Fischer. I kind of understood what he was getting at and it made me happy because:

a) I take the aesthetics of my working environment very seriously (which was one of the precursors of me leaving windows), and was glad that someone else understands that an IDE should be beautiful,

b) I’d clearly been so in love with netbeans that I had accepted her as “having a nice personality”

It’s true, when I first got netbeans I thought she was rather, how shall we say it…?.. plump, in the gui department. I remember the first couple of days trying to make a few changes here and there.. however, I fell so head over heals for her that I forgot all about this.

Until now.

Daniel called my gorgeous netbeans ugly, and while she’s not the cocoa supermodel that textmate is, I thought that was a little unfair. So, having been familiar with the gui for some time, I decided to trim some of the gui clunk out. Here’s what I came up with: Click here for a bigger pic

Here’s what I did…

I use netbeans 6, milestone 10 (get it here as my ruby on rails ide now. I’m a mac user, having moved from windows last year.

I was gonna write a blow for blow comparison of netbeans against radrails, but I really see no point. I figured it’s best just to tell you why netbeans’ rails support is so creamingly good, but so you know I have evaluated both and textmate, firstly – here’s some points about the other 2…

I often take this for granted, but then friends happen to see me do this and always ask me how it works…

It’s something I missed on os x after years of windows – the ability to create a new document just by clicking the right mouse button. Thankfall Nufile is a context menu plugin which exists for this purpose, it’s donate-ware and can be downloaded here:.

I’ve used it for almost a year without problems. You can customize it to add whatever file types you like, and even provide templates. The help on the website is really thorough, so I suggest you check that out.

Enjoy.

Having come from windows, I was looking everywhere for this!

Fortunately, some dude called Illari Scheinin wrote a couple of apple scripts that do the job. A link to his website and these scripts is here

He points out some apps you can use to run these scripts, they may be good or not, I don’t know because I use the excellent Quicksilver. If you don’t know about quicksilver, well go download it!

I’ll blog about it more in the future, but needless to say you can store both of these scripts in a suitable folder somewhere, which quicksilver is scanning. I have a folder specifically for apple scripts which I’ve set quicksilver to scan. It’s simply a case of dump these 2 script files in that folder, make sure quicksilver is scanning it, then set up a trigger for cut files.scpt (I did it with CTRL + APPL + X) and one for paste files.scpt (I chose CTRL + APPL + V). You can now select one or more files/folders in finder, and use cut and paste!

HOORAY! and thanks Illari!

I was doing a bunch of rjs stuff in rails, and lots of ajax goodness, and found myself constantly showing, and hiding the spinner and the update element (like a submit button, or other button)..

I’m a bit of a minimalist where possible and like to get rid of as much code as I can, and being as DRY as I can, and so I decided to make the following function:

1. function updating_field(field_name, finished) {
2. if (finished) {
3. $(‘spinner‘).hide();
4. $(‘update_‘ + field_name).show();
5. } else {
6. $(‘spinner‘).show();
7. $(‘update_‘ + field_name).hide();
8. }
9. }

I simply call this method from the onclick method, or sumbit method of elements on the page and it tidies up my code considerably.

1. <input type="submit" value="Save these changes" id="update_avatars2" onclick = "updating_avatars(false);" />

I can then call this code over and over again… In fact, I do, and I have many other helpers similar to this – which I’ll explore in other blog posts.

I don’t want to be a hater, but I’ve been doing Java recently, quite intensively, after doing a bunch of rails. Well, the other day I was on irc, talking to someone about my experiences, and this kinda fell out, and I like it, so here it is:

ruby is like, how shall I put it..? It reminds me of being in Cornwnall or a Spanish city

Java reminds me of being in London

...in the square mile

....at rush hour

When I was first learning rails I found one thing which helped immensely:

script/console

It’s the bees knees..

• when you’re starting out it’s like a safe ruby boxing ring where you can spar without getting your butt whooped,
• as you get a bit better you can practise new moves, and get some essential dojo in,
• once you know your stuff you can try out some severely funky moves without having to refresh the browser every few seconds,
• you can always nip into console and get your db sorted, check on db state, sessions, tidy some things up, interrogate your models and find faults, and perfect new bits of code.

I do all my practising, and probably a fair bit of debugging in script/console – if I’m ever doing anything new, or have a new idea it’s the first place I go.

If something’s gone screwy with my app, it’s the first place I go, and when I was starting out – it was ALWAYS open on my desktop.

I’ve written this up because I was just on irc, and for the umpteemth time spreading the word about script/console. Really, go discipline yourself.. Amy Hoy said it far better than this over on slash 7, go check it out:

I’ve been moving visualchat.co.uk to ruby on rails recently and one of the things they have to do is block certain ip addresses, in fact, entire ranges of ip addresses, as they get a lot of naughty mischievous chilldren (read as fucktards) creating havoc.

I tinkered about a bit and then asked on #ruby-lang where one David Black answered the call. The code he gave me is my favourite bit of ruby code ever. I think his solution is so very nice it’s unbelievable.
