Re: [rails-oceania] [Melbourne] Ruby Meetup this Wednesday the 29th of June
Hi all. I want to thank you for giving me the opportunity to talk about Fact Based Modelling last night. I hope that even those of you who've heard me before, learned something new about what I've been doing and why I think it's important. Thanks also to those who gave me positive feedback afterwards and who offered to help; please do contact me. If you want more information, read on... Most of the history of the project is in <https://github.com/cjheath/activefacts>, which is also where the master gem comes from; but now the project has been split into a few different gems (you get almost all of them when you "gem install activefacts"). The gems are: activefacts: pulls in the others and provides the "afgen" and "cql" command lines. activefacts-api: The Ruby DSL for fact-based programming. Although this almost stands alone, I am improving it to re-release as the "constellations" gem - almost ready! activefacts-metamodel: The model that defines the capabilities and meaning of a fact-based model (written in CQL), and exports it as Ruby code that uses the API. activefacts-cql: The compiler and verbaliser for the Constellation Query Language activefacts-orm: Provides an input module to convert from NORMA to CQL. activefacts-generators: The old generators framework and many generators. activefacts-rmap: Fact-based to relational mapping for the old generators. Replaced by... activefacts-compositions: The new framework for relational compositions (both for normalised operational schemas and for Data Vault), and new versions of most generators: SQL, Ruby, Rails (schema.rb and ActiveModels), documentation (glossary, graphviz, logical data model). This gem provides the command-line "schema_compositor", and is the only gem not included in "activefacts". You should use this! activefacts-examples: Many example models, in both CQL and ORM (for NORMA, and as image snapshots), and generated to most of the output formats (Rails, Ruby, SQL, etc).

Re: [rails-oceania] Undefined variable becomes nil in rvalue assigment to itself
Ugh, yes, sorry, brain fart, I’m thinking of something else. What’s the thing where the parser has to check local usage to decide syntax? There’s definitely a reason Ruby needs to know about local variables, even if they’re only mentioned in conditional code that’s not hit.

No. I think it’s a necessary feature of the Ruby syntax. When Ruby sees “x = 3”, it needs to decide whether you want an assignment to a local variable, or “self.send(:x=, 3)”. So it looks around the local scope for clues about what you meant, and when it decides that a word is the name of a local variable, it treats it that way throughout the function.

Re: [rails-oceania] Job market, junior / graduate roles
I think the preference for junior vs mid/senior developers is driven by culture. Between 1987 and 2007, development teams I was leading have hired a lot of developers; probably five hundred or more. Because were were working in languages that did not have a strong cultural aesthetic (read: “opinions”) we found that if we hired mid-level developers, people senior enough to have become good at a small range of project types, they tended to bring in their own opinions and defend them against our own - often rather different - company culture. A few of those did not last past their first project. So we found it was easier to hire new grads and help them to develop. Because we were doing stuff that was cool enough (and did things like sponsoring university prizes for software engineering so they all knew about us), we had no trouble attracting the very best and brightest candidates. Their ability for rapid growth counted for much more than intermediate levels of experience would have. In the RubyRails community, there is a strong aesthetic sense, a lot of quite uniformly-accepted opinions and conventions, so there are fewer problems hiring mid-level developers. You can pretty-much expect that they’ll fit in, at least as far as “the Rails Way” goes. That is intentional. Many of Rail’s opinions are sub-optimal, but we live with them and move on, and expect that others have been similarly assimilated. We’ve all taken that blue pill. Note that the above doesn’t reflect on senior developers. Most of us have experienced enough technologies to regard them with the same skepticism, and to use what seems to be useful, and get things done regardless. From the perspective of a 30+ year career, there are very few new problems, and almost no new solutions - there are just plenty of new names for old ones.

Re: [rails-oceania] How specced out should a development MBP be?
The other thing that doesn't seem to have been mentioned is the CPU and disk needs for virtualisation, so you can test all the browser versions in different VMs. Apart from disk space, VMs eat RAM for breakfast; allow at least one GB for each. I have an MBP that had a combo-drive which I removed to fit a large magnetic disk into, in addition to the smaller SSD. It's a good compromise given how little optical drives are used these days (can go external), but modern MBP's and Air's don't have drive anyhow. Clifford Heath.

It used to be the big win was having SSD over a spinning disk, but it looks like SSD is standard now regardless, so you can't really go wrong. More RAM is always nice for general OS responsiveness, so I'd go with 16GB preferably. 8GB is OK too though. Upgrading the CPU doesn't make a huge difference. Most of the time you'll be waiting on code to load from storage rather than time spent executing it - at least for development. Disk size really depends on what you're doing. Code itself doesn't take up much storage space. However, if you're wanting to deal with decent size databases for testing/analysis, you'll need to size it to fit. If you've got a lot of music/videos/games/other things, take that into account. Also consider if you want to run bootcamp and dual boot Windows - you'll need to set aside enough space on a separate partition for Windows (at least a couple hundred GB) -- @madlep Julian Doherty On 7 October 2014 at 12:01:35 am, Tim Moore (tmo...@incrementalism.net) wrote: As a counterpoint to the Air recommendations: once you go retina, you won't want to go back :-) On Monday, October 6, 2014 1:12:22 PM UTC+11, ben_h wrote: As others have said, any Mac from the past few years is fine.

Rosie, For backup, TimeMachine is excellent. A lot of folk use an Apple Airport Time Capsule, which backs up over WiFi, but I prefer faster backups with less WiFi pollution so I use an external USB drive. By default, you get a backup every hour for a day, every day for a month, every month forever (until space runs out) with automatic re-use of unchanged files, so a 1TB drive should last you forever.

After some musing, I came to the conclusion that you should opt for simpler code using simple concepts and cop the penalty of it being more verbose. Not everyone will agree I’m sure, and that’s cool. The advantages of having simpler code using simple concepts is that your code is now more easily understood by other developers with a lower level of Ruby knowledge. This is the same reason I try to not perform Ruby gymnastics in tests. If I do decide to use some more complex code, I use comments to explain what I’m doing. This was probably more important back in the day when hardly anyone used Ruby, but I still follow it. If you’re just consuming gems (not authoring them) and say, coding in Rails, you’ll rarely have a need to use Proc or similar concepts.

functional in this sense means having a certain capability.

After some musing, I came to the conclusion that you should opt for simpler code using simple concepts and cop the penalty of it being more verbose. Not everyone will agree I’m sure, and that’s cool. The advantages of having simpler code using simple concepts is that your code is now more easily understood by other developers with a lower level of Ruby knowledge. This is the same reason I try to not perform Ruby gymnastics in tests. If I do decide to use some more complex code, I use comments to explain what I’m doing. This was probably more important back in the day when hardly anyone used Ruby, but I still follow it. If you’re just consuming gems (not authoring them) and say, coding in Rails, you’ll rarely have a need to use Proc or similar concepts. So when you’re learning, I’d say don’t bother with Proc and fancy Ruby concepts. Learn other things that will get you more productive at a faster rate.

Re: [rails-oceania] Call For Awesome: Improving RORO brainstorming sesh
Acceptance of heckling is a personal-style thing, often dependent on your childhood family environment. Personally, I grew up with three sisters, and we ALL TALK AT ONCE at the table and it all makes sense, though visitors tend to find it alarming or at least disconcerting. So I’m cool with heckling (as long as it’s somewhat friendly and respectful) and it took me a long time to figure out why some people were so deeply affected and/or offended by it. When I had my breakthrough moment, I even prepared a lightning presentation about it… maybe I should deliver that? I’d like to suggest that no-heckling be the default, and folk who are ok with interruptions should actually *go ahead and invite them*. It’s really not hard to say “Feel free to stop me at any time and ask for clarification”. You have the stage, and you can always ask hecklers to pipe down and wait if it gets excessive. Oh, and recent talks have typically been TWICE as long as was warranted (by the material, or by the audience interest level). KEEP THEM SHORT, folks. That leaves time for anyone thirsty for more to ask you afterwards, and anyone simply thirsty to get more beer. Clifford Heath.

Re: [rails-oceania] Call For Awesome: Improving RORO brainstorming sesh
Heh, nice list. Not sure that RORO *should* attempt to meet all social needs, but I’ve been thinking about suggesting a couple of things, if anyone else is interested or can see a good way to help make them happen: * Go-carting day. Thinking of a 2-hour stint from 9-11AM on a Sunday at Eastern Creek. * Talk discussions on relevant health issues, especially spinal health (this is on my mind as my family is making a decision about spinal surgery…). Do folk think this is too far away from the reasons they come to RORO? * Take Ruby to the high-schools, especially high-school girls (thinking private schools here). The recent discussion on gender balance reflects a much wider problem than just the Ruby conference organisers, or the participants, or even the whole Ruby or tech communities. It’s a repugnant social ill that we squander half of the human race’s potential for technological innovation, and though I’m in admiration at the progress of RailsGirls, etc, we need to start younger. Primary school really, but practically, high-school may be possible. It will need IT-savvy women to make it happen, as it’s not something that blokes alone could credibly attempt. But perhaps we can help? Advocacy in government and education circles, too. Clifford Heath.

An intro to podcasting? Graphic design? etc. * Talks that are purely questions posed or issues raised thoughtfully, rather than solutions or news. * Support or training for people who would like to present something. * More accessible communication channels (than IRC I guess?) for beginners. * Survey co-workers who do not attend RORO meetups and bring their feedback to us. * Assistance organising lunch time learning and social activities with motivations similar to Jellys. * Resurrect improv night. * Invite all members to a communal github/SCM account and encourage them to collaborate. * Adopting some flipped classroom principles - support/homework workshops held to consolidate MOOCs/online courses/RailsCasts/online training material. * Fun small programming competitions/challenges. e.g. What is the English word that's letters can be rearranged into the most other English words? * Cupcakes and bakeoffs. Not. Even. Joking. AKA more diverse social activities open to all RORO members. * A job board, even though it might undercut the business model of our beloved president. * Archery at Rails Camps. * A web site that can both take donations and also illustrates where the money gets spent and what the priorities are. * Something that feels a bit more unified than the mailing list + irc + wiki, maybe something where I can put a profile picture and link to my github commit history and explain how to do magic tricks. * Magic tricks.

Re: [rails-oceania] Who owns the code and IP?
That's great stuff Warren. There's a further angle which has not been covered, which was decided in the High Court about 11-15 years ago. I will have to rely on memory and on my take-away from when I read about it. Sorry I cannot provide a proper reference, but this message may serve as a pointer. Basically when an employee is hired, they're hired because of what they can do. The fact that they then apply those skills to solve some problem does not create a restriction on their ability to solve that problem again for someone else. That would restrict the employee's future ability to practise their skills - it is a restriction of trade. This principle overrides any contractual arrangement with the employer. What it means is that any code you personally write - as an employee or as a contractor - is legal for you to recreate, even verbatim, in any future engagement. You may not take away a copy from your employer, but if you recreate it - even exactly, the employer has no recourse. If you recreate something which contain elements contributed by other employees during the same engagement, that is obviously a different story and normal copyright principles apply. I hope this pointer might stimulate someone more determined than me to search for the case details. They concerned a re-usable library that a coder brought to and substantially extended during a gig.

If your hirer wishes to own the IP, this must be specifically outlined in the contract. You may wish to seek legal advice about clauses relating to IP before signing the contract. This is different for employees, where the copyright DOES go to the employer automatically. Again, this is all speaking from personal research, and with no legal background - I guess at the end of the day, this just underlines the fact that you shouldn't rely on people on the internet for legal advice, as you'll get a multitude of opinions. :) On 26/06/2013, at 11:44 AM, Phil Oye phil...@gmail.com wrote: IANAL either, but that is consistent with my understanding.

Re: [rails-oceania] How to calculate an hourly, contractual rate
I was a co-founder at ManageSoft from 1990 until 2007, and we hired a lot of fresh graduates and saw them grow. Not web developers, but still… we had an expectation that people would move up at a certain rate from junior to mid- to senior level. The definition was roughly: A junior needs to work under some level of supervision, whereas a mid-level dev can take rough requirements and figure out how to negotiate, implement, test and deliver significant product enhancements of increasing scope. We didn't expect mid-level developers to be able to effectively mentor juniors; they only did that under combined supervision of a senior dev. Senior devs were always involved when work had cross-cutting scope or long-term ramifications. I'm trying to make several points here: * Mastery of the coding craft is only part of the picture; the team/community angle is more important, * Juniors that didn't progress to the bottom of the mid-level range within 18 months were almost always fired, whereas very quick learners could advance in only six months. * Seniors need to have many project cycles under their belt; they're expected to not only know how things *should* go, but also the many ways they can go wrong and how to avoid it. That almost always takes 8 or 10 years to develop. There are many more technologies in a modern web stack, so these durations will vary… but the point is that maturity is about being able to add value in the team. Juniors might have great coding chops but still suck as much value (or even more!) as they add, in the form of requiring supervision. Clifford Heath.

[rails-oceania] Single sign-on across Rails 2 and Rails 3 apps
Folk, A client needs to augment an existing Rails 2 app with some additional subsystems that will be written in Rails 3. The goal is to support seamless SSO across the old and new, and to achieve a single URL address space (one domain). The latter need can be met using a front-end haproxy or a Rack reverse proxy to forward URLs to the appropriate server, so each instance of the combined app appears to run under one domain. The existing user model has a pretty straightforward authentication model, and it will remain the owner of the subscription and login process. So it will serve authentication for the other subsystems. The method I'm proposing is a bit simpler than generalised CAS and SSO, which I think we can get away with because we can use shared secrets. Nevertheless I'd like your thoughts on possible failure modes or reasons why we shouldn't do this :). Assume that the user is logged-in to the legacy app already, and follows a link to the new app, which finds they're not already authenticated. It sends a redirect to the main app with a request-id encoded in the query. The main app verifies that the user is logged in and is authorised to use the new service, and constructs a ticket to send back via a redirect. The ticket contains the checksum (SHA-1 or whatever) of: * a shared secret * the current time, rounded to the nearest five minutes * the domain being served (the same server may serve users from multiple domains) * the user's name This ticket also contains the user name and domain in plain text. The new app takes its current time and rounds it down *and* up (two values) and tries to match the same checksum with either. If successful, it sets its own cookie and the user is now logged in. The time rounding allows for delays and for server clock skew. To handle logout, the legacy app has added to the users's session the fact that they attempted login to the new app. When logout occurs, it must force a logout there before logging the user out. So it redirects the user to each subordinate app's logout page, which redirects back to its logout page. When the last sub-app is logged out, the legacy logout occurs. Your thoughts? How have you implemented this? What existing gems do it?

Re: [rails-oceania] Single sign-on across Rails 2 and Rails 3 apps
Someone here has used ruby-cas happily. It handles cross-domain and uni-directional trust (only the CAS provider has to be trusted) without shared secrets, but requires the servers to talk to each other. I.e. works fine, but heavier than needed where both ends are trusted with shared secrets. Cassy, ooh, shiny. Thanks Radar, will check it out. SAML looks similarly generalised. You're not thinking of this I assume: https://github.com/onelogin/ruby-saml? Kerberos+LDAP: I've been deeply there before Rails - solved problems that Microsoft's core Active Directory team couldn't - but it's not our current environment. This needs to leverage off an existing Rails auth solution. If no-one pops my bubble, I think I'll prototype the solution I proposed. Clifford Heath.

Otherwise there is sibboleth which seems like a pretty robust solution. One other option you have Kerberos + LDAP. You can authenticate via Kerberos and authorize via LDAP. You can configure apache to use kerberos so it's minimal work on your app. The app then pulls information about the user from LDAP.

That code doesn't do encryption - it's just a byte-wise xor mask.
The Ruby equivalent is trivial.
In regard to encryption on the client side, the client should be regarded
as an untrusted third party. It must prove its authenticity in *every*
transaction,
by a signature applied over the entire message content. The signature may
be constructed using a shared secret or by use of a private key.

[rails-oceania] Railscamp, Twister source and the path forward
Folk, Awesome Railscamp. Thanks to all involved. I built Twister (a mutation testing tool, see below) and it's up on my GH account here: Ruby: https://github.com/cjheath/ruby/commit/ea99527feaf7dd06b3e8433ec640238441b188db RSpec: https://github.com/cjheath/rspec-core Here's my message to ruby-core, asking for help in refining this to get it accepted into Ruby itself. I hope some of you can either get value from using, or assist me in completing this work. Thanks also to Andrew Grimm for his moral support and constantly heckling me to keep pushing forward to this first working version, without which I might have just dissolved into a beery haze. Clifford Heath. Begin forwarded message: From: Clifford Heath clifford.he...@gmail.com Subject: [ruby-core:45706] Comments requested on implementation of set_parse_func Date: 19 June 2012 10:45:25 AM AEST To: ruby-c...@ruby-lang.org Reply-To: ruby-c...@ruby-lang.org Folk, I've implemented Twister, a new mutation testing tool to replace Heckle. It relies on a new hook into the Ruby parser, in order to modify what the parser thinks it has seen. Although I have written C extensions before, there are some aspects of the Ruby core which I'm unfamiliar with and as a result don't know the right way to handle. I'd like your comments, suggestions and improvements please. https://github.com/cjheath/ruby/commit/ea99527feaf7dd06b3e8433ec640238441b188db In particular, I'd like to know the following: 1) Do you prefer that I move the literal strings (which occur once each) to #defined? https://github.com/cjheath/ruby/commit/ea99527feaf7dd06b3e8433ec640238441b188db#L1R1003 2) Will this line of code mess up the GC, and how should I fix that? https://github.com/cjheath/ruby/commit/ea99527feaf7dd06b3e8433ec640238441b188db#L1R3853 3) The set_parse_func is extern though it should be static, but I need to move the rb_define_global_function out of thread.c. Can someone please tell me where I should move it to, since there is no Init_Parser? https://github.com/cjheath/ruby/commit/ea99527feaf7dd06b3e8433ec640238441b188db#L1R9029 https://github.com/cjheath/ruby/commit/ea99527feaf7dd06b3e8433ec640238441b188db#L3R4705 4) I think I should change set_parse_func to accept a flags argument and a block, instead of assuming all flags, and taking a Proc. What are the downsides of using a block instead of a Proc (does this reduce the number of Bindings that get created)? How do I change set_parse_func to use a block? The initial implementation of Twister is an extension to RSpec which adds the option --twist file-or-dir. It's still a bit rough - it needs to change the reporting on the twisted runs that follow the first (untwisted) run - but it does prove then concept.

But I don't think I could justify it in a work environment unless it was really mission-critical code (surely this would break most people's tests left, right and centre?). Of course it does - that's the whole point. If a code mutation fails to break a test, the test isn't actually *testing* that code path - even if coverage says the path was hit. Basically, heckle allows you to find out what your condition coverage is, instead of your branch coverage. Personally, I'm a believer… but lapsed. Not using it currently due to a project with a preponderance of integration tests, and too-large unit tests.

[rails-oceania] DAMA Melbourne and Semantic Modeling
Folk, I'm speaking on Semantic Modeling at DAMA (the international Data Management Association) Melbourne chapter next Monday. It's a fairly short sharp presentation that aims to show how SQL is inhibiting the relational data model's capability to promote project success in the software industry as a whole, how fact-based approaches can help, and what the data management community needs to do to make that happen.

Re: [rails-oceania] DAMA Melbourne and Semantic Modeling
It's about how Object Role Models (and other forms of fact-based modelling such as in my Constellation Query Language) can help in bridging the communications divide between business and IT. This communications gulf, which Martin Fowler refers to as the Yawning Crevasse of Doom is the primary cause of software project failures and blowouts, so anything that can help bridge it is worthwhile. Data folk are not normally seen as able to help, which is a pity, because they should be.

Re: [rails-oceania] Versioning associated models for future reporting
On 29/09/2011, at 12:01 PM, Chris Berkhout wrote: What about keeping old versions in the same tables, but marked with something like valid_until? Then you can always get the current version as of a particular time. There's no one-size-fits all for temporal data modelling, unfortunately. The three approaches are: 1) Include old data in the same table 2) Move data to a historical replica table, with a timestamp 3) Store compressed records or deltas. The problem with approach 2 is that it's hard to get it to work well when you have associated tables, like master-slave structures. Personally I like the valid_until approach, though I have implemented it wrongly in the past, using a NULL value for the current version. There's a number of reporting pitfalls if you use NULLs in this way. However, if you use a real date/time in the infinite future (maybe define it as OMEGA?), and trigger on insertion (either real DBMS triggers, or ActiveRecord hooks), you can modify the current record's validity to end now, and still index by time. For display, you can define either an AR scope or an SQL view to return the current data. This gets around many of the kind of issues that Ben raises. It is somewhat more work; but so is creating custom reports over archived records. If you need to make a lot of reports that display the state as it was at some point in the past, it works pretty well and is less effort than using record archiving. If you don't need much time-shifted reporting (perhaps just enough to satisfy occasional audit requirements), it's more work.

On 16/08/2011, at 5:55 PM, Andrew Grimm wrote:
What approach do other languages take to gsub?
That's not really relevant. The point is that Ruby already
has an interpolation syntax and rules for strings, and the
syntax used for interpolating MatchData values in sub/gsub
should have been as close as possible to that syntax.
Perhaps '#\1' for example (*). Instead Ruby took the Perl
path, the source of so many of its quirks.
(*) #{$1} would get interpolated before the sub/gsub got
called, of course. An alternative would be to define a type
of string modifier that delays the interpolation. For example,
you could have a string: \foo#{$1}bar where the initial
backslash marks the string as to be interpolated when the
value is next accessed (as opposed to right now). It would
come at the cost of creating a closure though.

Re: [rails-oceania] Re: Meetup on 30th of June - Speakers welcome
I had negotiate for a speaking slot (to fill my analog blog commitment from last time) with Michael Morris, and have prepared a talk on Comet with Sinatra, which is based on my bayeux-rack gem and jquery.comet client-side code. If you don't know what Comet it, it's basically asynchronous messaging from server to browser, using AJAX requests. Comet is regarded as being a little old-hat now, but socket-io doesn't have support in any Rack-based server, so folk have been forced to jump to Node.js or run a second server to get asynchronous messaging. There are other alternatives which implement long-polling, but not as simple and sweet as what I'll show. Or so I think anyhow!

So in my gemspec, I have this line: p.spec_extras[:extensions] = 'lib/activefacts/cql/Rakefile' A Rakefile in your extensions gets run after installation. So I call Treetop to generate the Ruby files there. You could add a gem with a Rakefile that checks for the required packages? No comment on the cleanliness of this mode of operation.

Re: [rails-oceania] Looking for a nested / colourised log output gem
On 04/05/2011, at 10:55 AM, Michael Pearson wrote:
I've been writing a lot of system automation tools lately, and one
of the things I'm trying to get right is status output.
But I've been thinking about verbosity and task nesting.
And I'd like to write code that looks like:
Logger.task(Making a new container) do
blobs.each do |blob|
Logger.task(Making new blob #{blob.name}, :verbose = true)
...
end
end
end
Before I go and extend our own libraries, does anybody know of a gem
that already does task-based nested log output?
I have a non-colourised tracer module I use and (mostly) really like.
Personally, I don't like most colourised displays; I think whitespace
and very few well-contrasting colours are enough. Anyhow...
I've been meaning to extract it into a separate gem, and would be
happy to work with you on that. The main feature it adds that you
don't mention is support for categories, so you can control exactly
which kinds of messages get included. Any trace may have a category
symbol, and/or a block.
See https://github.com/cjheath/activefacts-api/blob/master/lib/activefacts/tracer.rb
.
The ActiveFacts API doesn't actually contain much tracing, but the
rest of the project uses it extensively.
You just include tracer.rb, and can write code like:
trace Just getting started here
trace :overview, I'm doing some big thing here do
...
trace :detail, You might not want to know about this do
...
end
trace :summary, All done ok
end
You configure it through API calls, or by setting the TRACE
environment variable
to a simple list of category names. As a special case, all means
everything,
and help means dump a complete list of the categories that were
encountered
during the run, so I know what I can enable. In addition, if you
specify a category
name with a trailing underscore, then when a block is found of that
category, all
tracing is enabled for the duration of that block (even categories
that weren't
previously enabled). So TRACE=overview_ would enable everything in the
above.
One thing: when debugging traced code, the Ruby debugger wants to step
into the trace method before it yields to the block. It's an annoyance
that it
has no step to the first line in the block attached to this
statement. However,
I've tried to minimise the number of steps required to get from a
trace call
to the first line of the block. if the code looks a little strange,
that'll be why.
Sometimes the code that executed in the interpolated string (a)
contains many
steps to step through and (b) affects runtime performance when tracing
is
disabled. I attempted to get around that by passing a Proc which is only
eval'd if the trace is enabled, but I encountered a performance
degradation
on long test runs which *may* be attributable; so it's disabled. Can
anyone
confirm whether such Procs leak?

Re: [rails-oceania] Re: Skinny Controller, Fat Model ...
On 25/02/2011, at 8:52 AM, Lachie wrote: I'm not really sure what you're expounding. Are you talking about something like DAOs (Data Access Objects) in Javaland for persistence, Business logic in different objects? Thinking about it some more, I think the reason we don't use separate Persistence and Business objects in Rails is because ActiveRecord does enough for free, through magic that separating the two becomes YAGNI. I'd agree that its not Pure™ but its pragmatic. ActiveRecord is easier to use than Hibernate because it doesn't separate the business objects layer from the persistence layer, but that also makes it less flexible, and in particular less able to deal with legacy databases. When you start applying AR to legacy databases, even assuming that you get past the roadblocks of ID columns and multi-part keys, you find that the model objects are often structured in a way that clashes with the way you'd like to structure your domain logic. When you're working green-fields, AR works pretty well (your 'pragmatic' comment). Also, I think the trend to name the data layer as the model is incorrect. The entire program is a model. The data layer is an *information* model, the controller layer is a *process* model and the view layer (with some controller help in Rails' case) forms the interaction model. My point is that all three layers are models. I call these three models Information, Process, Interaction, rather than MVC. I think that gives a clearer idea of what should be in each layer. It also makes it clear that a more effective language for writing controllers could be had by designing it to explicitly model business processes (where a controller action is a process step). I'm not at all happy with Rails' approach in this regard. You *only* have actions, and nothing which links them together into a process view. Affordances in the UI, rendered as URLs or whatever, reflect possible process transition paths; but in Rails these are devolved to the interaction (view) layer, which is wrong in my opinion. Affordances are the key thing that creates the process view, and Rails pushes them out of the controller where they belong. The controller should explicitly make each affordance available for rendering (by the view) in the same way that data is made available. This would pull the whole process model back into the controller where it belongs. As it is, Rails has a weird concoction of url helpers, view renderers and controller hooks that together encode the process model. Note, by process I mean a business process, not logic (which usually belongs to the information layer). Any code which derives from, aggregates, or otherwise manipulates persistent information belongs in the information layer. The process layer can then use that information (whether stored or derived) to make process-flow decisions, and to route to/from the interaction layer. It should not contain (as Rails controllers usually do) code to derive or aggregate results (beyond simple :include type aggregation).

I found it very interesting approach (especially for larger scale projects) but haven't seen much chatter about it so I thought I'd throw it out here to see what other people think. I hadn't seen this post or the acronym before, but this is really not a new invention. It's just traits, which I (and others) have used in designing systems for more than a decade. It does seem to work nicely with Ruby though. Regarding the model/controller debate, in my view a controller is responsible for animating the process model. I.e. is this request valid in this context, and what should we do next? Everything it needs to know to direct that decision must come from outside the controller's context. There are four sources of such information that I identify: The request parameters, the session, the database, and the current configuration of the system (this includes the current time). Sometimes external systems also contain relevant state. You might also separate out the authorization data as a separate data source. Ultimately however, every controller decision is essentially based on a query which spans those fact sources. If each such source supported a single query interface, then controllers could be built on top of explicit query statements. I modelled a system like this once (although it was actually built in standard Rails), and the exercise was very interesting. I think it's a fruitful direction for further work.

then you get urls like http://foo.com/bar:8080/sign_in which is,
of course, totally not right.

On 02/02/2011, at 9:44 AM, Ben Still wrote: I was an avid MS Project person until a few years ago, and I think for some reason MSP has become some kind of default for how you might manage a project. I used MSP for pretty much everything, but with the benefit of hindsight (IMO) it is pretty inflexible. It provided a false expectation of how long a project might take and how it's going. Totally agree. I use a deep task/goal nesting, where you can estimate, work and assign iteration/phasing at any subtask or supertask level. Many tasks get done for this iteration while still having things outstanding for a future one. This was especially the case when working on code that had to be implemented (differently) across many platforms. You need to handle the fact that software is never done and often, neither is a task. In the late 90s I extracted the schema from MSP Server's SQL database and used it as one of the seeds for a new web-hosted design, but that never got funded. I think it could have been an excellent product however. We now rely much more on stories and use Jira and Greenhopper for managing and scheduling tasks. Tasks in the real world don't neatly line up and change from todo to done - they need to get worked on, QA'ed by someone, perhaps a bit more work, and then closed. In other words, each task is a mini project by itself. How well does Jira handle that? We've also made some stuff to pull information out of Harvest and Jira and show this on a wallboard http://redant.com.au/blog/the-story-behind-our-wallboard/ That's really nice. you might get further along by finding an existing tool (there are thousands out there) and then building something that works with that if you need to. I've not seen one that handles the richly structured hierarchy that I use and want, except the indented plain-text files which are my current fall-back.

Re: [rails-oceania] Re: parsing xls files
The question to ask is what actual protection is provided by GPL's copyleft (as opposed to any other open source license). In the 1980's, any code that was released freely, under any kind of license or copyright terms, was regarded as fair game for incorporation into commercial closed-source software. Sometimes entire systems were simply adopted and adapted and released with commercial support, but more commonly, it was just subsystems. The GPL changed that, by providing a legal body behind the protection of open source authors' rights. It took twenty years - vis the Linksys WRT-54G wireless routers which used Linux, and the GPL forced that platform open. But my belief now is that the threat posed to author's rights is now fairly small. The other thing that the GPL achieved was in forcing such platforms open, to allow public scrutiny and improvement of a vendor's products. This occurs in several ways: (a) by direct open source replacement of the vendor's firmware (OpenWRT) (b) by the vendor adopting improvements from such efforts and (c) by not wanting to be embarrassed by continuing to use software that has been revealed to have weaknesses. So far so good... I hope I've established my case that the GPL served a necessary purpose. But... most software now being created is not subject to such risks, and therefore doesn't need such protection. In fact, it can be counter-productive, as I'll show. GPL advocates would argue that *all* software should be open. That's unrealistic in the extreme - the majority of many company's IP is in their software, and though a lot could survive or even benefit from opening it, a lot could not, also. On 28/11/2010, at 10:38 PM, Robert Postill wrote: what about GCC or Sphinx or any one of a cornucopia of utils we use with Ruby? Open software provides the best available support for widely-used standards (thinking of zip/deflate, OpenSSL, etc), and we benefit because those things *are* standards. That doesn't imply that they must be GPL, only open. Imagine if vendors all had to roll-their-own compression and encryption to avoid exposing their entire software IP! Many products would simply not exist, or would exist in a much inferior form. I'm glad that these open source tools did *not* use GPL licensing - I think we're all better off for that. None of the native tar implementations was light years ahead of the others but they all had annoying bugs or limitations that just weren't in the GNU software. They were all extended from the basic UNIX tar in order to support features of the proprietary systems (symlinks, ACLs, etc). They also fell behind the standard and so became incompatible. But when you chose GNU tar, you were effectively saying that those added features didn't matter to you. Or that if they did, you or someone would add them to the GNU version. Good move, but wouldn't it be better if the original tar had been designed with an extensible tagged metadata system which allowed proprietary variance without proliferation of custom versions? The opportunity to refactor or rewrite comes from the open nature of the software, and GPL forced that to happen when as an industry we believed we all could do do better on our own. I wouldn't want to go back to that and I see GPL as a important defence of the things I don't want wrecked. I don't think that any substantial part of the software world would or could go back in that way that you fear. We should be able to take our car to any garage or know that the life support system we depend on isn't using a buggy math lib and the GPL is the crowbar that allows that to happen because it makes it hard to use GPL code without being open yourself. I'd certainly not want a car or a pacemaker that displays the kinds of flaws which are widespread in open-source software. The ability to dig in and fix it yourself is just not comforting, and shouldn't get used as an excuse for buggy software, as frequently happens now. My conclusion: If you want to give something away, then give it away without reservation or regret. If you want credit, require that with a copyright and open license - but don't try to limit how others may use your gift. Clifford Heath (the first Unix geek graduate in Melbourne). Wow, you're even older than I thought you were :) Just couldn't resist that one Hehe. Better to be old and wise than young and stupid.

That's not even theoretically possible in a parallel system. All you can do is code each transaction semantically (add 1 to X rather than set X to old-X+1) and then rely on database serialisation to make it work. In order to reduce deadlocks, you can use intent-update locks (which AR's :lock gives you) or just ensure that multi-record updates are ordered (i.e. if you update A then B in one transaction, you never update B then A in another). With long-polling or websockets, you could potentially notify the user that the record they're seeing has been updated, but you'd have to think that through from a XP point of view. However, I don't think that's what Chris was concerned about. It seems to me he was worried that while I'm looking at some data and perhaps changing it, but haven't yet submitted my changes, someone else will submit a change that make my changes invalid. The correct answer is to detect that using versioning or row- value checksums, where the check value is hidden in the form I will submit, and must match if my changes are to be accepted. The nice thing about doing this with checksums (as opposed to versions) is that if the record is large, and I'm only looking at a subset of the fields, I can have a checksum over just those fields, rather than the whole record. When I submit, the record is re-fetched and those fields re-checksummed. As long as *nothing I was looking at* has changed, my update is still valid. In most applications. YMMV. You might not have encountered a situation where this was even possible... but for example, the Claims table in an insurance app might well have a hundred fields, and those will never all be shown at the same time. You could break the record into separate records and use row versions for each, but then your UI is leaking into your schema.

[rails-oceania] Fwd: [Fwd: Regulator warns Australia's finance industry on cloud risks]
Hmmm. Relevant? I think so. Clifford Heath. Begin forwarded message: Original Message Subject: Regulator warns Australia's finance industry on cloud risks Date: Wed, 17 Nov 2010 05:34:44 +1100 From: Don McKenzie 5...@2.5a Newsgroups: aus.computers,aus.electronics Regulator warns Australia's finance industry on cloud risks By Brett Winterford on Nov 16, 2010 4:56 PM (12 hours ago) APRA's cloud computing fears published in open letter. The letter will prove a blow to U.S.-owned cloud computing providers such as Amazon's EC2, Salesforce.com, Microsoft's Azure and Google's App Engine - all of which to date are hosted elsewhere in Asia. Australian banking regulator APRA has written an open letter to the financial services industry, urging executives to view cloud computing as a new form of outsourcing or offshoring that requires the regulator's tick of approval. The rise of cloud computing has - as formerly expressed by CSC chief technology officer Bob Hayward - caught the regulator by surprise. Earlier this year the regulator stepped in to apply pressure on one wealth management firm that had endeavoured to migrate its CRM system to Salesforce.com, hosted in Singapore. Today's letter [PDF] - first reported on technology news site Delimiter - reinforced APRA's view that cloud computing is still untested technically and legally. The regulator said organisations migrating services such as messaging and calendaring, collaboration and CRM to the cloud be concerned about serious risks to the business. While these applications may seem innocuous, the reality is that they may form an integral part of an institution's core business processes, including both approval and decision-making, and can be material and critical to the ongoing operations of the institution, APRA said in the letter. APRA has noted that its regulated institutions do not always recognise the significance of cloud computing initiatives and fail to acknowledge the outsourcing and/or offshoring elements in them, the letter said. As a consequence, the initiatives are not being subjected to the usual rigour of existing outsourcing and risk management frameworks, and the board and senior management are not fully informed and engaged. Regulated institutions are reminded that, under the prudential standards on outsourcing, they are required to consult with APRA prior to entering into any offshoring agreement involving a material business activity. APRA expects that any outsourcing project that could hinder an organisation's ability to manage risks effectively or have a significant impact on the institution's business operations requires the regulator's approval. Those wishing to embrace the cloud are required to undertake a comprehensive risk assessment around the type of service, the service provider and where it is located, and the criticality and sensitivity of the IT assets involved. APRA has observed that, to date, assessments of cloud computing proposals typically lack sufficient consideration of these factors, the letter said. http://www.itnews.com.au/News/238817,regulator-warns-australias-finance-industry-on-cloud-risks.aspx Cheers Don... -- Don McKenzie Site Map:http://www.dontronics.com/sitemap E-Mail Contact Page: http://www.dontronics.com/email Web Camera Page: http://www.dontronics.com/webcam No More Damn Spam: http://www.dontronics.com/spam USB Isolator 1000VDC For Protecting Your PC OR Laptop http://www.dontronics-shop.com/usb-iso-low-full-speed-usb- isolator.html These products will reduce in price by 5% every month: http://www.dontronics-shop.com/minus-5-every-month.html -- You received this message because you are subscribed to the Google Groups Ruby or Rails Oceania group.

I really like this approach. The trickiest part of having the DOM involved in JS is that the DOM can simultaneously be the Model *and* the View. This structure forces to you to separate that duality. MVC originally served the purpose of each model serving an unknown number of views of potentially disparate types. In most situations that doesn't happen and isn't needed however, and the value of separating the model from the view is less. If the Model is a JS object, and the view is a DOM object, and they're closely coupled one-to-one, that serves most purposes. So on that I'd agree with Korny. If you have a bar chart with values above each bar, there's no need to separate (for example) the bar height from the displayed value, as two separate views - it's simply overkill. Do it as one view instead. It's really important that the model is passive and the controller separate. That's what makes it possible to configure the model through settings, and tweak the behaviour by changing the controller. Finer-grained customisation is usually not needed, since we have CSS to set most view details.

Re: [rails-oceania] How should we handle our data?
No disrespect to Anthony, but if you have an N^2 algorithm anyhow, doing it in memory is smarter than getting SQL to do it. It depends on whether your algorithm and how you can pivot the data to reduce the complexity. I've handled this class of problem by loading all the data into memory. Loading using Active Record might be too slow for this though, so consider using Model.connection.select_rows with some hand-written SQL, and building the Ruby structure you need without using AR. You can index the data multiple different ways with very little incremental cost, even if some of your computations won't need all the indices. Clifford Heath, Data Constellation, http://dataconstellation.com Agile Information Management and Design On 13/05/2010, at 2:43 PM, Sean Seefried wrote: Hi all, I've got a question that I hope generates healthy debate and perhaps even a solution for me. Without going into too much detail I'm working on a project in which we perform calculations on a large hierarchical data set. We haven't used the acts_as_tree or acts_as_nested plugins because each level in the hierarchy has a well defined role and various attributes that only fit at that level in the hierarchy. To give you a brief taste the hierarchy roughly goes: local government area, precinct, building type, consumption. For a given local government area the number of records contained in the entire hierarchy is about 8, the bulk of them being consumption records (since they are the leaves of the hierarchy). A feature of the project is that one should be able to perform a projection of consumptions into the future. This is a fairly complex algorithm and involves looking at all 8 records and combining them in various ways. This algorithm, naively written, has a huge database latency. The bulk of the time is spent querying and receiving results from the database. We have had some success in optimising various parts of the algorithm by performing less queries. A lot of the time this means that we pull the records out of the database and put them into some kind of look-up structure (a hash with a key equal to the attributes (plural) of interest in the model). This allows us to do a kind of in memory query but, annoyingly, only on whatever we choose as the key for the hash. You can no longer perform general queries on the collection in memory. Basically we lose all the expressiveness/terseness of ActiveRecord. What we really want to be able to do is this: 1. We want to pull a large collection of objects from the database into memory 2. We want to be able to select subsets of these in-memory objects with a similar flexibility to querying them using ActiveRecord 3. After having updated them in memory we want to be able to write them back to the database. I should metion that none of their unique keys will have changed. We want this to be some kind of bulk update. Some approaches that I've thought of but I don't think work: - Simply caching will not work because, as far as I know, this only works when you perform the same query twice. We are not doing this. We're querying the collection in many different ways. - This isn't really an issue to do with the kind of database. Switching over to CouchDB or an Object Database doesn't obviously solve our problem. The problem is that although we know in advance that all our queries will returns results that are a subset of the collection of 8 objects we want to be able to perform many different sorts of queries returning many different subsets of the 8 objects. Having the objects all sitting in memory really seems to be the way to go. - We could also just create a class hierarchy that mirrors the hierarchy of the data and forget about ActiveRecord entirely. We could then just serialize this structure and write it to disk or a database. We don't get the advantage of being able to query the data structure this way though. Some final notes: a) This site will, at most, have a few simultaneous clients so having all 8 records in memory should not be a problem. b) We've had some luck with bulk-update part of point 3 above. Zach Dennis' AR-extensions plug-in has been quite useful. This email is still not as clear as I wanted it to be even though I've spent some time on it.

Yes, when you test first and you're fluent in rspec and your chosen mocking framework you can write the tests and the code in 20 mins flat, but until you get there... there's not as much of a (buzzword alert) ROI on automated tests (sorry!). So, how do you get yourself/your teammates to perservere with the learning curve until you reach that zen/enlightenment stage of testing? We all know it's worth it, and sure there's the you must eat your all your vegetables before you can have any desert approach (i.e. complain loudly on the bugtracker), but unless you get (another buzzword) buy-in from teammates/management it doesn't work so well.. I think I'm rambling now but I think (at least for me) what makes testing hard is not testing itself, it's testing *productively* and *getting new-to-testing developers who don't know (beyond the testing mantra) why they should bother to test* which is most difficult. Anyway, I can't actually attend any roro meetings/debates so feel free to ignore me :) Also, compared to this audience I'm a relatively young pup in the ruby world, so please feel free to turn your nose up at my naive ramblings... but I felt like adding my 2c.
