Is this a reasonable application for Ruby?

Joe Percival

3/10/2006 5:22:00 AM

I have a box that retrieves data from a weather station as well as a
number of video cameras. I would also like to grab some graphics files
from external FTP sites and execute some gimp comands to generate
animated graphics. There are a number of other data sources that I
would like to access, parse into xml files and upload to my web app.

Also, I have to develop some routines to deal with recovery from
unexpected program termination (we live in an area with unreliable
power). I need to develop routines that figure out what time it is when
they wake up, and execute specific applications at required times.

Are these reasonable applications of ruby? Since I am going to be
learning Ruby anyway for RoR, I thought maybe I could use Ruby for this
kind of task rather than trying to do it all in MS Dos Batch files
(which would require re-learning the intracacies of DOS).

Thanks,
joe

Yes. The devil is in the details, but overall these are reasonable
tasks for Ruby.

There are nice libraries for working with ImageMagick (not sure about
GIMP), plus Ruby ships with the REXML XML parser. (And you can use
libxml as well, if you prefer, thanks to recent reactivation of that
project.)

We lent them too much money before, so we now have to lend them money
so they can pay us back, because if they didn’t we couldn’t pay back
the money we owe, which would mean it would cost us more to borrow
money in future. And then where would we be?

Yep, that just about sums it up. I blame the [economics] teachers.

What's it worth at auction?
Noticed a lot of direlect shop fronts morphing into halal butchers and
asian seed shops lately. Local health inspection guy told me that they
are under pressure, it's all too fast and new.
So how comes a charity shop that can get a rebate of 80% on rates,
plus decent lease deals have to close, and a halal butchers can thrive
without the same benefits? Full rent, full rates, and hardly any
customers.One building was a former Portuguese bbq/cafe turned out to
be a brothel come pot joint. I have been watching a Turkish barber
massage the same guy's head now for weeks. How is he paying rent and
rates for his shop with that kind of customer base?
The Thornton trust has gone upside. They would own a lot of Lurgan
based commercial properties, and probably half of Portadown high
street and almost all of the town end of Thomas street.What's the
craic with that? Big investment or just able to make more and live
for less.

All the guys were eating. I arrived too late to order(umpiring away).
The locals were served Porterhouse steaks, the Indians had plates of
the most colourful veggie stuff (looked like mashed tropical fish).
Ali Z was sitting, still in his whites, watching on. Ramadan. The sun
had almost gone down, but Ali was saving himself for his 'approved'
meal at home (I don't mean at home in Rawlpindi). He must spend a
fortune driving to Belfast, just get proper meat before our local
halal Sal started up.
There is a market for everything and everybody

I was in a branch of HMV last week. A biggish one with the two
floors. Music on one, DVD's films etc on the other. The stock on
display must be worth tens of thousands of pounds if not more.

This was in the middle of the day with plenty of people about. For
the two floors there was only one till open and even then there was
nobody about you had to wait by the till until an assistant came
along.

Its always been the same in every branch of HMV I've ever been in.
Hardly any tills open and no queues. Their prices have to stay
competetive up against Amazon and their own website. So how they
can manage to pay their rent, heating bills, rates and wages on what
you see (not) going through their tills has always seemed a miracle
to me.

Same with the big DIY sheds nowadays. Bursting at the seams with
stock and all of the tills deserted for most of the time.

As you mentioned sundown there, maybe the Halal butchers do all their
business at a funny time of day when nobody else is about. The customers
maybe have big families who all mainly stay indoors. And so again go
unnoticed.
