Re: Getting the latest related record from a SQL DB
Why not include a sub-select like, ... where album.published = (select max(album.published) from album join artist on album.artist_id = artist.id) ... Paul On Thu, Oct 9, 2014 at 5:28 AM, Andrew Beverley a...@andybev.com wrote: Hi guys, I'm after some best-practice advice regarding SQL database design. I have a table (say artist, couldn't resist...) that has a one-to-many relationship to another table (say album). The album table has a field which references the artist table's ID. So one artist can have many albums. So, if I want to know all of an artist's albums, that's easy. But what if I want to fetch an artist's details and his latest album? I can select the artist from the artists table and then join the albums table. But to get the latest album I'd have to use a max function (say on the album's date), with which it isn't possible to get the related fields in the same row. I see 2 ways of solving this: - Run multiple queries to get the relevant album's ID (if even possible) and then retrieve its row in entirety. - Have a reference from the artist table back to the album table, specifying which is the latest album, which I update each time the albums table is updated. Neither seem particularly tidy to me, so am I missing something completely obvious? Thanks, Andy

I'm not sure I understand the question here, or moreover why you want to do
this..is it just an intellectual exercise?
I do actually have a use for it, which would help to explain the
question.
A large part of Number::Phone is based on data in google's
libphonenumber project. That has, for most countries, regular
expressions that match valid fixed lines and valid mobiles. For some
countries those two regexes can both match some of the same numbers.
Here's the data:
http://goo.gl/hTBAhZ
If you look at the data for Barbados, they have for fixed lines:
246[2-9]\d{6}
and for mobiles:
246(?:(?:2[346]|45|82)\d|25[0-4])\d{4}
I'd go out on a limb and say that the complete list of overlapping
situations all share a /^prefix/ like this. (This doesn't necessarily
help you since you'd have to exhaustively falsify it but if you're
going for the quick win I bet just looking for prefixes gets you
most/all of the way.)
then some strings will match both expressions - 246230, for example.
But if you look at the data for Jamaica there are no strings that match
both regexes.
At the moment I detect these overlaps (and then throw the regexes away
as being unfit for my purpose) by just going through each country's
number space. This is practical for NANP countries as I can do it
all with only about a million comparisons in the worst possible case. It
would be impractical to apply this to the whole world though.
If your goal is to simply identify overlaps rather than generate
encompassing regexes, you could try attacking it with
intelligently/heuristically generated random numbers.

Re: Heathrow Pushchair on BA
Indeed. I've done about 55 flights on Ba this year, including 12 with a baby and pushchair. At check in they'll add a baggage tag to your chair, and you just push it though security. At boarding they call you first and you leave the chair by the plane. At most airports you can have it delivered back to the plane on landing. However with a 12 month old we found it easier to leave the chair at check in and carry the scamp in a sling. For check in, I leave things quite late, but then I fly several times a month ad cant afford to waste the time. Leave a little longer for security - especially if you're taking baby liquids, and unexpected nappy changes. Security at heathrow can be a pain, there's no way to predict it. Even so, 1h30 should be fine. But I'd aim to get to heathrow about 2 hours just to be sure as you don't want to be stressing, you dont know the airport, and the tube can always get held up. I believe there's a kiddie play area in t5, somewhere near gate 7 once you get through. I think you get 1 bag each, up to 23kg, plus 1 bag for the baby, plus a pushchair, plus a car seat, plus 1 piece of had luggage each, plus 1 for the baby, plus 1 personal item (handbag, laptop bag etc) each. I'm not sure how a two-piece travel system works as far as how many bags it takes - as a frequent flyer, 2 parents and baby get more bags than we can fit in the car, they used two tags for our chair/wheels combo. We took both through security. If you're on a long haul flight, it will probably go from B or C gates, which invokes a train ride after security. Certainly keep the pushchair with you in that case. By best Ba flight was exiting the taxi at 0955, and sitting down on the plane at 1002 for a 1005 departure. That was at Manchester, and I was very lucky.

We've just booked a flight and have a couple of questions about it, which I was wondering if anybody who's flown from Heathrow terminal 5 or travelled with a pushchair on BA before will be able to help with. How long do we need to allow for getting through terminal 5? We don't want to set our alarms unnecessarily early and have to fill time at the airport, but obviously we don't want to miss our flight either. The booking information says that we need to drop bags off by 45 minutes before departure and have entered security at least 35 minutes before departure. Any guidance for translating this into 'time by which we need our Tube to have arrived at the platform' gratefully received. We'll have bags to drop off, and ideally will be avoiding stairs and escalators. Our other question is about flying with buggies, especially with BA. The flight information says our baby can take one fully collapsible pushchair (stroller) in addition to his checked luggage allowance. Does this mean the pushchair gets handed in with the checked luggage, and we have to carry him through security and the gate without? Also, any idea if fully collapsible means something different from collapsible to BA -- does our buggy have to be particularly small when folded in order to be allowed on at all?

Re: Alternative sources of Perl programmers
I work in a variety of offices around the world. This year my most frequent office has been Jerusalem, about 12 days there, and a couple more up the road in Ramallah and a bit further in Gaza, but I've been to another 8 or 9 on top of that. I'm almost up to 70,000 miles this year, and on my 51st flight of the year while I write this. When I'm not abroad my commute is down stairs into the study. My effective line manager has an insane schedule. He's in Moscow this week, Delhi next week, Singapore after that then Bangkok. This helps a lot, as my real line manager hasn't got a clue about the stresses of (economy class) travel. I'm hoping to be Europe bound for the next 2 weeks, with just day trips or maybe an single overnight, but Delhi, Joburg, sydney, Jakarta, shanghai, new york, kabul, washington and Singapore all need my attention in the next few months. I'm looking forward to my next long haul day flight as I'll get a change to get my teeth into writing some new code (Perl of course). The lack of distraction from email and phones is really useful, but it makes network development a bit harder, and I get funny looks when I string two laptops together on the plane!

Learning and being productive in a language is far more than just syntax; in fact that's probably the easiest part since they're largely the same, unless you're learning something radically different. By far the lion's share of the work is the libraries, error messages, documentation, and toolchain. From my own experience, if I'm day-to-day productive at a being-paid-for-it level in say Perl, I tend to swap out a bunch of Python knowledge. Sure, I can swap it in, but as ever there's quite a cost to that. Spending one's day constantly referring to Stack Overflow, Google, CPAN, and perldoc is workable but it's slow.

Or (yet another analogy): perl is to programming what smoking is to workplaces - something you do in the comfort of your own home - or in a shelter outside specially constructed for the purpose. There's possibly an easier explanation than any conspiracy theory. At some point perl fell out of favour to PHP with the CGI process start up problem, and mod_perl's complexity and perhaps even early bugginess (perceived or actual). At that point its usage declined and it got stuck in a positive (in the control theory sense) feedback loop: usage drops, so a business case needs to be made to counter usage dropping, so usage drops, GOTO 10. Meanwhile other languages (PHP, Python, Java, Ruby) catch up and surpass Perl, each on their own various dimensions: PHP's ease of install, Python's relative language simplicity, Rails having a big successful commercial backer, Java an enormous subcontinent of cheap labour, etc. Now, Perl in a sense has two problems: its relatively low usage, and that the other languages frameworks have caught up in some cases surpassed Perl's, so Perl's advantages over other options just aren't seen as that compelling. Perhaps Perl's biggest problem though is it still uses - as a method invocation operator. (Heh, kidding… kinda… not ;) Anyway, those are the two areas I would look into: 1) getting real stats on perl's usage and seeing whether the perception matches reality -- maybe there is a dark pool of perl users that aren't being counted 1b) making perl more accessible, e.g. meetup.com, facebook, etc rather than just this mailing list 2) drawing up a list of really compelling reasons why perl is a good fit for various tasks. And possibly being OK with the battle having been lost in the short/medium term on various fronts (web frameworks) Key IMO is acknowledging the power of perception: maybe perl is amazing at X, Y, Z but if it's not perceived that way some marketing is needed rather than intellectual discussion.

If you're working in the web and haven't added memcached to something,

But not sure _why_ you want to learn Mason, if it's for an existing site then the book may be of use. New job, old tricks new to old dog Have to confess, I didn't realise Mason (1) was quite *that* old I've learnt enough Mason in the last year to keep an old site up and running and extend it as required before it gets replaced by a .net system. (Yeah, yeah.) From my point of view, there's little to recommend using Mason nowadays. Mason 1 that is, I have no knowledge of Mason 2. The only advantage I can think of is that you might like its templating system. Personally, I don't really, but I can believe that others might. Disadvantages are that it's tied to mod_perl. I believe that means that you can't bring plack into the equation which, in turn, means that you can't take advantage of the plack middleware. I'd be pleased to be shown that I'm mistaken here. Additionally, each template is in the same namespace, and is basically the body of a subroutine. This essentially means that you can't use named subroutines in templates. You can look on this as encouragement to move your logic into modules but, as Leo notes, the other side is that the components can get very messy if you don't heed this encouragement. And then I had to hack Mason itself in order to get code coverage information from the components. I managed alright with the online book that Dave mentioned, but I wasn't trying to learn it thoroughly - just well enough. My best tip, if you need to work with Mason, is to look at the compiled code in the mason_cache directory to see what's really happening. -- Paul Johnson - p...@pjcj.net http://www.pjcj.net

If I end up buying a laptop with Windows or OS X installed I shall definitely give it a go first. I've been developing primarily on Ubuntu running in VirtualBox for a couple of years or so now. I started working this way because Linux doesn't (didn't?) run well on either my desktop or laptop, though it's fine on my server. I find it to be quite a comfortable way or working, with few problems and some advantages. The main downsides for me are that deleting large directories on shared folders sometimes messes up and requires the disk to be unmounted and remounted (solution, try to remember to do that on the native OS) and that whenever I do something with Windows and it wants to be rebooted, I need to stop or suspend the VM. I tend to use notion as my Window Manager and I leave one frame blank and view in Seamless Mode. This means that the host OS is visible in that blank frame. I've put the VM on an SSD and given it access to all the CPUs, so it's quite speedy too. -- Paul Johnson - p...@pjcj.net http://www.pjcj.net
