My lama says that you should allow your subjective pain to awaken compassion for others that also suffer from whatever condition you are suffering with. Then take the medicine!

I no longer need to take antidepressants and I put this down to many years of practice. But Buddhist meditation is not therapy: it’s goal is enlightenment. This is why the Dharma is taught.

That said, calming meditation really helps to clear the mind of that nagging negative voice that informs depression and damages your chances of happiness in this life. I did this by learning to recognise it and then prevent it gaining energy and starting a loop in my mind. My personal experience is that it is like having a constant noise in your mind that spoils everything and makes it very hard to think and feel anything but despair that it will never end. Eventually you move on past it. Or I did, anyway. I also found the first Noble Truth, impermanence, a great help, because it meant that the was a light at the end of the tunnel and my pain would end.

A friend said (probably a quote somewhere), “if you are going through hell keep going until you get to the end”. Good advice I think.

Bootnote – here is another post against the same topic

I do’t need to focus on the pain – it’s always there, constantly. I just do’t give it any energy any more. I recommend the Tibetan practice of lo johng (not sure of spelling) – “sending and taking”, which the Dalai Lama describes in one of the “Essential Teachings” series – need to track the proper reference.

I also would’t embark on this without some instruction from a qualified teacher.

Another thing that came to mind recently – and sending and taking starts with this – is to forgive and love yourself first, before you try to give things to others. If you hate yourself the taint of the hatred will devalue whatever you give to others, and make it hurt more too!

Strongly recommend “The Art of Happiness” too, wonderful gentle book.

… and that’s why I use RoR. 90% of the “anti” opinions here don’t get it. It’s quick, it has a low entry barrier, and, if you want the Ajax stuff, it’s very easy to do simple things. If you want stuff that scales to the moon then you use a technology that will do that – d’oh!

Ruby has also got lots of nice utilities to do SOAP and so on. It just works and it does’t hurt. Integration with other services (.Net or Java) is a breeze and you can get help really easily from other people in the community. In general there is only one way to do something (because the language is young) and it does what you want. Compare with Java – 25 frameworks with alpine learning curves (XML or properties files – let’s have both!) before you can do anything. It used to be simple and pretty easy to get things done but the signal to noise ratio is really painful now and getting worse with every “improved” J2EE implementation from the big vendors. Me no want no stinki’ entity beans – they leave a stain on your teeth.

I am a Java certified web developer and would’t go back, except for the cash. It used to drive me crazy: make a change, run Ant, deploy the WAR file, waste 20 minutes doing nothing. Get shouted at by PHB for reading El Reg while all this was going on. This is typical if you work on a legacy system.

Now I can just get stuff done, and that’s all I want. I’m really keen on the whole JRuby thing, where the Rails app will just run from a WAR file and use all the sexy scalability stuff that the Java people have spent so much time and energy on – but I’ll happily use it at one remove, thanks.

Here lies the one that works, not the old one I posted ages ago. It also uses dates instead of timestamp differences and should therefore not break if you ask it to go before the Epoch (some time in 1970 I think):

Adrie’s comment left on my old blog pointed this out (he’s much cleverer than me!) – it’s really trivial:

s is the start date and e is the end date (s is lower than e)

(e.month - s.month) + 12 * (e.year - s.year)

See!

module DateUtils

  class << self
    def months_between(date1 = Time.now,date2 = Time.now)

      date1 ||= Time.now
      date2 ||= Time.now

      if date1 < date2

        recent_date = date1.to_date
        past_date = date2.to_date

      else

        recent_date = date2.to_date
        past_date = date1.to_date

      end

      (past_date.month - recent_date.month) + 12 * (recent_date.year - past_date.year)

    end

  end

end

Thanks a lot. helped me much

doesnt this neglect the actual day of the month? there isn’t 1 month between 2/1/11 and 1/31/11, but this would claim there is…

ok – but “months or part therof” is a long method name 🙂

Start here to see what this is i response to. 

… how many of you go back to the pre-web days? I do – graduated in 1987, I’ve had to practically start again 3 or 4 times in the last 20 years – Unix before Linux, X-windows, dumb terminal to client-server, pre-javascript web tech, javascript, hand crafting your own stuff in raw html, Java, PHP, Java again, Rails. All I’ve ever wanted to do was deliver systems that work and meet real-world problems in a usable way. Be able to go home at the end of the day feeling I’ve achieved something and the people who use the stuff I wrote can do their jobs more effectively and not be dehumanised by it, hence my dislike for techie arrogance, which I see all the time.

2.0 is a Tim O’Reilly marketing thing, because he saw a lot of problems with the current technology and wanted to have some kind of dividing line to help people distinguish between things. But like the man at ucov says: no business model, no idea what people want, groovy idea that recycles some stuff other people have already failed at = failure. I’m with Paul Graham on this one – work on something boring and painful (for the punters) and you will see the rewards. Shiny is’t necessarily good¹. You seem to have bought the marketing hype.

I applaud people’s enthusiasm – I want technology to work and help us get out of the social and cultural ruts we’re beginning to die from (a rut is a grave that has’t had the ends filled in yet). Debate is healthy and really useful. The best “manifesto” is something people find useful and the culture that coheres around it. I’d rather work on that than an essay, any day.

Did’t realise that phorm were the timewasting bastards who were behind 121 – spent many a happy hour trying to get rid of their viral nonsense from a machine my then 10 year old son was using (no idea how they got past him not being an administrator).

Can I send them a bill? I think they also managed to hijack firefox a while ago by putting in a bogus (and invisible) add on so I had to trash everybody’s settings directory to get rid of it.

DEFINITELY send them a bill, and then a summons through the county court for my time. Anyone else want to join in?

Bloody hell! Although I suppose it might save us from tourists (joke, definitely joke, I hope). Is there any forum you can have a go at them about wasting public money? There’s an idea – why not get off your backsides and do your job preventing it? Maybe pay for some police officers with the cash you just threw down the bog?

It’s like the “ID cards stop terrorism” argument – how exactly? Unless you are going to start something like the pass laws like they had in South Africa under apartheid? And we all know who will have their movements restricted, don’t we? All of the guys on 7/7 were UK citizens and would have had valid ID. No-one suspected anything or they would have done something about it. Gah!

The authorities have to be seen to be doing something so they spend money on paranoid crap like this.

I am a Rails developer who uses a proper IDE (Netbeans for Ruby) and Windows. Installed Cygwin to give me the bash shell and the other tools I need to talk to our Linux server backbones. I started on Unix/Sun workstations, went to client/server stuff then on to web. DHH is a kid, bless him, and has’t yet lived through the next big change that will make him realise he has to start again. I’ve done it maybe 5 times in the last 20 years. Experience of one’s own ignorance makes one humble. He’s on a high now. Losing your job is a great and unwelcome teacher, believe me.

I don’t get the Mac thing, either. If you don’t want windows Ubuntu is fine, has the sexy desktop thing and runs on more powerful kit that costs a quarter of the price.

Don’t get me started about TextMate – it’s a word processor with a bunch of arcane key combinations to run a pile of bundled bash shell scripts. I could probably do something similar with Vim or Emacs but don’t need to because the nice guys from Sun have written very good free tool. Can’t split a view of the same file – just like a word processor all you can see is the few lines around where you are working. http://francis.blog-city.com/debugging_rails_applications.htm

Following on from the talk I gave on why Java is bad for your brain at Barcamp I thought I’d dig out some of my old blog posts and present them here – try and explain the argument (which is more of a feeling of disquiet tha anything else) better.

download mind map here (save as)

I tried to embed the map in an applet – but the downloaded applet does’t work and locks the site up. There is a Flash reader but I lost the will to live Java, eh?

Create an active record object, retrieve some stuff from a soap service and then get this:

NoMethodError: You have a nil object when you did’t expect it!
The error occurred while evaluating nil.has_key?
        from /usr/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/base.rb:2172:in `has_attribute?’
 

If you’re having trouble with active record suddenly throwing exceptions it’s probably because of a namespace collision with your Soap classes defined in the generated file called default.rb, or YourClassName.rb depending upon what arguments you gave to the wsdl2ruby command.

You need to put the data transfer classes into their own module by adding

—module_path MySoap

to the end of the command line. So you have something like this:

wsdl2ruby.rb —wsdl my.wsdl —type client —classdef My —module_path MySoap 

(remember to delete the old files!) 

I last fixed this by hand editing the files and adding in the module definition – so this is by far the easier way.  

Another problem is you get this:

NameError: uninitialized constant SOAP::Mapping::EncodedRegistry 

Just put

gem ‘soap4r’

in the mapping registry file

XML – sigh

I read Oracle’s early papers on XML DB – “we store the schema and the data separately, with pointers into the data”

Codasyl in disguise. The same with the o-o databases, hierarchical databases – none of this is new at all.

Personally I can write SQL, I understand the syntax and have been using it for over 20 years. Once you realise you’re really working with sets it’s pretty easy to understand.

RDBMS is now just another commodity. I’m happy to use whatever comes next, I currently develop in Ruby on Rails / MySQL and hardly ever have to see the database directly. Interestingly, the people who designed Active Record made 90% stuff really easy and then allow you to drop into raw SQL for the complex, instead of retrofitting the kitchen sink.

I’ll use whatever comes down the pipe, as long as it meets my needs – that’s it.
