Maybe emacs users should do more to promote it. Emacs has a reputation of being overwhelming. But we don't promote emacs enough. There are great reasons to learn and use it. I don't think emacs is difficult to learn, there is a great help system and an interactive tutorial to begin.
Emacs does have a ton of functionality. A co-worker asked me about the enormity of the emacs key sequences, not to mention the number of functions that can be run by name. I've used emacs for 27 years, so I'm not the one to speculate on the effort to learn it.
But one thing to remember is that across all the different editing "modes" (for editing this language or that one, or text, or email, or file systems, or what have you) most of the commands are the same and others simply apply the same concept to a specific mode. e.g. what does it mean to go forward and backward by a word or a sentence or an expression or function definition?
See an emacs command summary. I could not quote a lot of these for you without acting out the sequences with my hands. Emacs is now in my physical hand memory.
My favorite emacs function may be "query replace". This function at first may seem not unlike any kind of interactive find-and-replace dialog on a Mac or Windows.
But query replace (found on the meta-percent key combination for those following along at home) is enormously rich. First, query replace will attempt to preserve case in the replaced text. e.g. if you replace "foo" with "bar" and the function encounters "FOO" then you have the option of replacing it with "BAR" and if it encounters "Foo" then the replacement will be "Bar".
What if you want to replace a found match but then edit that particular match slightly differenty before continuing on? (Otherwise you have to remember to go back, and where to go back to, to edit that specific replacement. And what if there are several variations?)
In this case when prompted for a replacement, type control-r for a "recusrive edit". Now you are in a position to edit that specific replacement before continuing with the search for the next match. If you want to do the replace and then review the replaced text before continuing with the next match, do this: type comma "," to do the replace but remain at that spot. You can type control-r to recursively edit the replaced text or do the usual to continue on.
control-meta-c escapes the recursive edit and continues with the search.
What if you made a mistake with the previous match? Either you should have made the replacement and didn't, or you should not have made the replacement. Type "^" and query replace takes you back to the location of the previous match with the text in the state as you left it.
Enough already. Emacs is one helluva tool. There may be other tools with just as broad and deep an array of functions. If you don't have one already, give emacs a try.
The real problem is the so called "bail out" - just look at the wolves
lining up for a piece of the action. Look at the terms and conditions.
That's reason enough to say "no, thanks".
"Radical decentralization has got to be a big part of any solution to

I'm for it - with one exception - the state boundaries are artificial.
We have states and cities bordering each other on rivers. The lines
should be drawn around a more natural "bio-region" as they say.
For example the right size for where I live would be the Columbia
River Watershed.
Radical decentralization would be the best move this country could
make. All the more reason it will never happen, in this cynic's
opinion.
"Frankly, I'm amazed there aren't (yet) riots in the streets. These public purchases of overpriced assets are a transference of wealth from the poor and middle class to the wealthy on the grandest of scales. Apparently "liquidity" means the ability of the wealthy to unload their bad investments on the public.
The most absurd result of all this is the blame being placed on the "free market" when it is exactly the lack of a free market in currency (via handing a monopoly on currency that caused credit bubble."

People generally are disconnected from Washington DC, or even their state and local governments. At least locally they see levies and propositions on an understandable level: do they want to spend $X on the fire department or a library.
At the national level, I've been surprised for years that we're willing to just spend incredible amounts of money on the aftermath of a war that had always been based on documented lies.
This current fiasco is just more of the numbingly same. Paulson - "Give me $700B on the condition that you must have no oversight into how that money is spent."
Oh, did you know that's the condition? That's spelled out literally in the proposal. I will never vote for any of my representatives who back such legislation.
Folks - at least fellow citizens of the USA - we are being *taken to the cleaners* on this. This is a *fiasco* of the grandest of scales. Look around at who's already lined up to get their piece of the action. There is no way this much money can be put on the table without a lot of shady behavior.
In this case enough of the shenanigans are taking place right out in the open to cause riots in the streets.
As for whether a purely free market could do better - I'm not the expert. I'm skeptical there could be such a thing as a "purely free market". It's a system, and people work the system for their own goals. Sometimes those goals are admirable. Most often not.
The term "free market" is used by most politicians and financiers as rhetoric to get what they want, for themselves and their cronies. Period. That's human nature.

Wednesday night on "The Daily Show," Jon Stewart hit Karl Rove and
Bill O'Reilly with damning evidence of their hypocrisy regarding Vice
Presidential nominee Sarah Palin.
While Rove recently praised Palin's experience as the mayor of
Wasilla, Alaska, Stewart showed video of Rove trashing Virginia
Governor — and former Richmond Mayor — Tim Kaine's executive
experience, listing all the cities that are bigger than Richmond and
calling such a pick "political."
Then, after recent video of O'Reilly describing Bristol Palin's
pregnancy as a family issue, Stewart showed a clip of the Fox News
host blaming Jamie Lynn Spears' parents for her teenage pregnancy.
Finally, after showing video of Dick Morris complaining about the
rampant sexism in the media coverage of Sarah Palin, Stewart unveiled
a clip of Morris saying that Hillary hides behind the sexism defense,
and that anytime "the big boys" pick on Hillary, "she retreats behind
the apron strings."
"In Dick Morris' defense," Stewart said, "he is a lying sack of sh*t."
http://bitworking.org/news/363/pinch-me
PALIN: "I have protected the taxpayers by vetoing wasteful
spending ... and championed reform to end the abuses of earmark
spending by Congress. I told the Congress 'thanks but no thanks' for
that Bridge to Nowhere."
THE FACTS: As mayor of Wasilla, Palin hired a lobbyist and
traveled to Washington annually to support earmarks for the town
totaling $27 million. In her two years as governor, Alaska has
requested nearly $750 million in special federal spending, by far the
largest per-capita request in the nation. While Palin notes she
rejected plans to build a $398 million bridge from Ketchikan to an
island with 50 residents and an airport, that opposition came only
after the plan was ridiculed nationally as a "bridge to nowhere."
In the context of the RESTful-JSON group, Bill de hÓra compared the
discussion there on URLs for JSON object attributes to using URLs in
RDF from a subject to either a literal or another resource (URL).
Which led me to reread Bill's piece from a few years ago on attempting
to automate the linkages between HTML forms and form elements and
updating resources designated in a service using RDF...
http://www.dehora.net/journal/2005/08/automated_mapping_between_rdf_and_forms_part_i.html
This aspect of REST, i.e. the client side being more general, and not
one-off for a specific model, is still lacking from what I have seen,
for RDF as well as now for JSON. For JSON the solution seems to be
send down the Javascript that is aware of the model expressed in JSON.
I think the same would be true for RDF, except when you get into the
need to make inferences, and so on, then more processing is required.
For either RDF or for JSON, modelling conventions are needed to be
more generically expressive in the client per se. Otherwise
conventions are needed server side to map from simple forms clients as
discussed by Bill.
So anyway... now I am interested in RDF and going a bit deeper with it
than before. I see the RESTful JSON development leading very quickly
into discussions of conventions of usage - what is a "collection"?
what is a "reference"? and so on. So I picked up a new good book
reviewed not long ago by Danny Ayers...
Danny Ayers...
Which led me to a comment on that review by Rowland Watkins. He commented...
"I am surprised that RDFS is still being used (except for certain
relationships), let alone RDFS-Plus - mixing RDFS and OWL is not a
good idea (this may be stated in the book). Unfortunately, FOAF still
suffers from RDFS/OWL (making it OWL Full). Still takes a bit of
searching to find the OWL DL version…"
Which catches this non-semantic-web-insider by surprise. A web search
did not turn up anything about mixing these not being a good idea. I
see a lot of discussions about subsets of OWL (lite, DL, etc. as well
as semi-custom) and so on, for decidability, performance, etc. But I
am wondering what the state of the semantic web standards and
implementations really are?

I think this is the key issue, yes. So far there is one reasonable
RESTful client application: the browser, generally. (Well, and email
clients, arguably.)
Some thoughts...
Good RESTful clients should be more secure than the browser, more
"rich" than the browser, and more easily programmed than the browser
(i.e. easier and more expressive than ajax). Good RESTful applications
should not require "one-off" programming on the client side. Nor
should they expect all the client components to be developed in any
single language, or run in a single runtime container.
From Google's v8 documentation...
In V8, a context is an execution environment that allows separate, unrelated, JavaScript applications to run in a single instance of V8. You must explicitly specify the context in which you want any JavaScript code to be run.Thank you.Why is this necessary? Because JavaScript provides a set of built-in utility functions and objects that can be changed by JavaScript code. For example, if two entirely unrelated JavaScript functions both changed the global object in the same way then unexpected results are fairly likely to happen.
In terms of CPU time and memory, it might seem an expensive operation to create a new execution context given the number of built-in objects that must be built. However, V8's extensive caching ensures that, while the first context you create is somewhat expensive, subsequent contexts are much cheaper....
With the V8 snapshot feature (activated with build option snapshot=yes, which is the default) the time spent creating the first context will be highly optimized as a snapshot includes a serialized heap which contains already compiled code for the built-in JavaScript code. Along with garbage collection, V8's extensive caching is also key to V8's performance, for more information see V8 Design Elements.
When you have created a context you can enter and exit it any number of times. While you are in context A you can also enter a different context, B, which means that you replace A as the current context with B. When you exit B then A is restored as the current context. This is illustrated below:
Note that the built-in utility functions and objects of each context are kept separate. You can optionally set a security token when you create a context. See the Security Model section for more information.
The motivation for using contexts in V8 was so that each window and iframe in a browser can have its own fresh JavaScript environment.
How many artists of any medium have been on the top of their profession for many decades and then produce one of their greatest works?
B.B. King is one. "One Kind Favor" is his latest album, which is not only great, but one of the greatest blues albums ever, and one of the best collections of music of all time. Well, in my opinion.
No surprise that T Bone Burnett is the producer. King is no slacker at age 76, but Burnett was the perfect choice to draw this one out of King.
If you don't run out and get this music, you may as well stop listening to everything altogether. There would be no point in continuing.
From Big Picture, "Women Are Heroes"...
View of the facade of some houses at the "Morro da Providencia" favela, one of the most violent of Rio de Janeiro, Brazil, taken on August 20, 2008. The French photographer identified as JR is launching a project called "Women Are Heroes", through which the photographs of women, relatives of the victims of clashes between the police and drug traffickers, were placed in the facades of the houses. This project already took place in Sudan, Sierra Leone, Kenya and Liberia, and will be taken to India, Cambodia, Laos and Morocco after Brazil...Though Rio is blessed with natural beauty and climate, it still struggles with large disparities between rich and poor, and many of the six million residents reside in hillside slums called favelas.

He turned a collection of his Portland Confidential columns into an entertaining book, whether you are from Portland or just enjoy reading about the real underbellies of society that many folks would just assume you ignore.
What happens when all of Old Town becomes New? Currently it appears the underbelly is headed about 80 blocks east of downtown and beyond. Is that any better? I guess for the real estate developers downtown, it's out of sight and far away for a while. Does a healthy city need something of an underbelly?
I remember moving to Portland 20 years ago and all that is hip in the Pearl District and what's fast becoming hip in Old Town was really very rundown. Still in spite of all the improvements every block displaces more people living on the edge with few options. It's easy to say getting rid of this one adult bookstore is an improvement, but most likely, as Stanford lays it out, the builders and real estate developers are the low-lying movers and shakers in city politics, and they are on a mission that considers little more than how to keep their gravy train flowing. Another former "house of prostitution" closer to Powells' City of Books, if you know where that is, is about to become a McMenamin's hotel. Well, that could provide an entertaining motif.
One group of folks my family, friends, and I have helped with every now and then for the last 15 years or so is Potluck In The Park. David Utzinger works his butt off every week making sure everyone who can get downtown can get a good meal; every Sunday. No one knows the last time he took a week off, looking back well over a decade. Plus they throw a party every Christmas day, and a huge barbecue every summer. There's no better group I know of that's just bare-bones, keep people fed and give them a place to socialize every week of the year. Most people in this kind of need aren't homeless, but if Portland continues revitalizing its Old Town, and similar blocks, there will most likely be more people on the street who currently at least have a roof.
Oh yeah, the small O'Bryant Square, the original "Paranoid Park", they've barely been able to hold on to for their Sunday dinners is also up for "revitalization" and PLitP has been trying to maintain some visibility in the "visioning" process. PLitP had already been moved out of the nicer park blocks several years ago. There were no problems, it's just such a large, weekly gathering of so many people in need, is just a bit "unseemly" for many people.

The same three of us have been programming in groovy in ernest for the first time. We've each dinked around a bit at one time or another previously.
Overall I like it. Especially closures and the syntax for block closures when the receiver's last argument is a closure. The spectrum from programming nearly all-like-java on one end of groovy style, and programming nearly all-like-lisp-and-smalltalk at the other end of groovy style flows more smoothly than I initially gave groovy's designers credit for a few years ago.
One quirk - bit me for a dozen minutes or so, the oddity/convenience that groovy wants the keys of a map to be strings. What bit me was the expression...
where foo and bar are variables.
{ foo: bar}
The "convenience" groovy provides is the interpretation of foo as a string, i.e. "foo". The value for the pair is still the result of evaluating bar. So you end up with the pair (if bar is the integer 1)... "foo" : 1
If foo has the value 3 and you'd like the pair to be... 3 : 1 then you have to put foo in parentheses to force evaluation...
That's the closest thing to a true quirk I've encountered. But for parameter lists, etc. the convenience does pay off in neatness. The result is a very smalltalk-ish keyword message send, and combined with the block closure syntax, is a pleasant and familiar style for smalltalk-lovers. (e.g. coding a seaside-ish web framework using paul-graham-ish closures rather than continuations would be very fitting in groovy.)
{ (foo): bar}
Meanwhile the other affect groovy has had is that now when I edit java code, I'm forever not using semicolons at the end of statements.
Oh, and the tools still really suck.
Three of us have been using git with a shared (git) repository on a server. We've been pushing and pulling to/from the shared repository as opposed to peer-to-peer just as a matter of convenience and familiarity.
I have to say I like the concept of distibuted version control, or more to the point: versioning locally, pushing, and pulling. This is the first I've used such a tool. Mostly I've been using svn for the last few years. We've not tried the svn/git combo pack, just because we did not need or want to use svn in this case.
I also have to say after a couple two three weeks of using git, I am not crazy about git per se. Aside from just the learning adjustment that this is not svn and this is distributed version control, the adjustment and learning about what I would call the "quirks" of git have been somewhat discouraging.
I'd compare some of the cryptic language of git to some of the cryptic error messages a programmer new to erlang sees, or haskell / complexly type inferred languages. Combined with a vocabulary only a kernel linux hacker could appreciate, I suppose. I don't think this language is due to the concepts of distributed version control per se, rather to git's implementation and implementors.
And whatknot.
So git seems to be winning. I've not tried mercurial or other distributed repositories. Is git so good? Or just the one that's winning for reasons other than usability? And stuff.
I just love the trial and error that goes into making these contraptions.

Manning has a draft PDF available of a new Erlang book, with an emphasis on OTP, the platform/framework/library/what-cha-ma-call-it that helps in the development of robust, concurrent, distributed systems. I bought it, yes, I did. Co-authored by Martin Logan - no relation that I know of, and no damn discount on the book either!! (Well, I didn't ask. :-)
There are only a couple of draft chapters currently in the draft. But this should be a good addition to the growing supply of help getting going with Erlang.

This scenario was fun to evolve -- I settled on the approach fairly quickly, it wasn't a really difficult configuration, but getting the angles and positions just right took a few iterations. The to see the creation finally make it to the target - it is alive!

that De Icaza and Microsoft have pretty much a completely open
relationship, they give him free flowing access to all the .NET API
documentation and their developers, he spends a good amount of time on
the Microsoft campus in Redmond, and Novell and Microsoft are
committed to both making .NET run on Linux. However, Novell and
Microsoft can only do so much to have the community contribute efforts
to keep .NET development at pace on Linux with Windows."
Yeah, right. The most successful software company on the planet could
fund the work if they wanted to. Maybe Linux is not a priority
Microsoft, I can understand that. Maybe Novell has enough troubles of
their own to get Microsoft's software running on Linux. I can
understand that.
Adobe has Flash / Flex / AIR running just fine on Linux. This is not a
technical problem. It's an organizational / business problem.
Maybe Linux does not need Silverspoon. Isn't open source a meritocracy
for software?

After several levels I became stuck on a theme of using a lot of wheels, multiple vehicles, and not attaching the goal object. This one is my current favorite...
Free for basic play. $10 to save and share, building scenarios, etc.
There are some amazing contraptions built by others. I'll link to some of them later, like the "thrower" - just great.
Someone built this "Orbital Launch" contraption which is just out of nowhere... first the goal object gets stuck in this pocket and you wonder will it ever get out. Then after a few revolutions the object and a chain attached to it are launched... but apparently *away* from the target. The object flies out of view for what seems like forever... only to drop down from above.
The gods must be crazy. It makes no sense.

"The OTP is a collection of GoF-style patterns for Erlang."
And I had a reaction to the current state of patterns, generally.
I think this list, as well as the software community as a whole, has
lost sight of the original intent of the "patterns movement".
The original intent of a "pattern" is the format of the information,
more than the information per se.
The format should be written in (one of several) pattern styles. The
overall presentation of some set of patterns should form a "patterns
language".
So to say the "OTP is a collection of patterns" is true only in the
worst definition of "pattern".
A really useful pattern language for OTP would guide the programmer
from some initial kind of problem through the application of some
patterns that address that problem and associated forces that would
direct the programmer through a set of choices and partial solutions,
toward an overall solution.
And stuff.
Really good patterns take a lot of effort. This alone explains the
current state of patterns, generally.

Portland, Oregon
September 17-19

My kids have never been to a drive-in. Although I've driven past the

old for me to drag them along. It wouldn't be the same. Going to the
drive-in with my parents as a kid in the mid-60s meant watching the
first movie then climbing in "the way, way back" (which is what we
called the back of the station wagon) and falling asleep.
More things about movies my kids know nothing about: the cartoon
before the show; the _intermission_ in the middle of the movie; the
_second_ movie (and third, at least at drive-in shows).

http://www.infoq.com/news/2008/07/use-case-or-user-story
My position is why either/or?
Use Cases, in all their variety, tend to be larger descriptions of
existing or desired features. Within this larger context, the team
(developers, users, etc.) should try to break down features in many,
smaller units of work. This is usually what's meant by User Stories.
So, yeah, you need a larger context in which to understand desires, in
which to determine what the next best small units of work to focus on.
I'd not heard of this before, but apparently some people don't like Erlang's "single assignment" semantics. What this means is a "variable" actually isn't. A variable becomes "bound" to a value via pattern matching. Once bound to a value, that same variable in that same lexical scope cannot be re-bound to some other value. Within that scope that variable must subsequently match successfully against the value it currently has.
What appears to be an "assignment" in Erlang is really just the simplest kind of pattern match. Below X10 is matched against foo(X) and since X10 is not yet bound, it becomes bound to the value of the function.
f(X) ->
X10 = foo(X),
X15 = fab(X10),
X20 = bar(X15),
baz(X20).
Some people are concerned this could lead to uncomfortably renumbering variables, say, when the function fab should be added in the function above.
I dunno. This seems contrived, or at least rare, or maybe machine-generated. If you just have to "re-number" a few variables, no big deal. If you have to renumber too many variables then you'd be better served by decomposing an overly long function that also suffers from inexpressive variable names.
The author of the post is apparently writing a ruby-ish language for the Erlang runtime. More power to you.
But there is a lot to be said for a simple, mostly functional language that wants you to keep functions short. When I am writing in an imperative, even object-oriented, language, I want my procedures to be short. And I want one variable to have one value. The code is more "tractable" when short, and variables don't vary.
Then the name becomes essentially a mnemonic for the value.
The overwhelming majority of programmers have only used languages with multiple assignment.The overwhelming majority of programmers over my 25+ years of programming experience write procedures that are much too long, even when they are otherwise well-written. That's the first bad habit people seem to adopt, or never learned to avoid. I've worked with long, run-on procedures in every language I've encountered.
Lisp? Yes. Smalltalk? Yes. Pascal? Yes. Even these languages with their gifts for brevity cannot overpower the usual programmer's inaesthetics.
Understanding what many, small procedures do is always better than understanding what one or a few long, run-on procedures do. The payoff is there because you learn what you can put aside, and what you should pay attention to. On the other hand, long, run-on, convoluted noise is always with you. You never can put any of it aside - you have to revisit, remember, and ultimately revolt and/or refactor.
In an imperative language a variable should take multiple values only as part of an iterative statement. In the statement "for i = ..." the variable i should only be updated by this statement. Or in "while someCondition ..." the variable someCondition should be assigned an initial value before the while and it should be updated immediately before the while re-evaluates its decision to iterate again.
Write short functions. Use the shortest name that yet conveys the meaning or purpose of its value. Assign them once even if your language is imperative. Generally this will keep your stress level low, as well as the levels of those who pick up your code later.

Joe Gregorio wonders about hardware support for functional languages...
I've been thinking about this in the context of the Professionalization of Scripting Languages, does anyone know if any of the processor manufacturers are working on adding silicon support for activation records?I know first-hand Intel has been searching for ways to spend transistors for at least a decade. There's been some looking at objects including closures, generally, and some consideration of Smalltalk, Lisp, etc. But I am not aware of specifically looking at stack vs. heap allocation of activation records.
On the other hand I have witnessed decades of considerations of hardware support for functional languages. In each case the problems seem to have been solved at least as well with general-purpose hardware combined with clever software at compile-time and run-time. Looking back at the history of hardware support for Lisp and Smalltalk, and OOP and functional programming generally, will turn up many research and production efforts that have not panned out in the long-run. However the economics may have changed assuming scripting languages will become as "professional" (!) as Joe predicts.
I've been paid well from time-to-time over 25 years to program with sophisticated dynamic languages. That today we're just now thought to be entering a "professional" stage is an indicator that the profession is missing some of it's own literature. So please consider the following. From my historical viewpoint as a veteran dynamic language applications programmer, and dynamic language implementation aficionado, I believe activation record solutions you seek have a rich history of solutions to continue from (so to speak), and they are almost all in software.
Scripting languages are direct descendants of what I would consider long-time "professional" languages such as Smalltalk, Common Lisp, and Scheme. Until recently I suppose there's been little motivation for Ruby/Python/Javascript language implementers to dive into the literature of _implementing_ their predecessors. I would recommend anyone serious about it to begin with "the original lambda papers". Not that these were the first on efficient dynamic languages, but they start from first principles and are easy to read.
From there I would recommend moving on to work published by Appel, et al. for Standard ML/New Jersey (SML/NJ). A starting point is the text book "Modern Compiler Implementation". But this should also include all the research done around compiling ML.
Along the same lines are all the years of work around compilers and run-times for Scheme. SML/NJ and Scheme have particularly interesting activation/closure needs because they are mostly functional, but do have side-effects, and they also have first-class continuations. Look up various work by Kranz, et al. at Yale (in particular for the Orbit compiler for "T", a dialect of Scheme); Dybvig, et al. at Indiana U.; Feeley at U. Montreal; and Clinger, et al. at U. Oregon and Northeastern.
And then include the publications about Smalltalk, Self, etc. implementations by Peter Deutsch, David Unger, Craig Chambers (U. of Washington), and Eliot Miranda among others. Generally reading through the years of OOPSLA proceedings, especially the earlier years, and the proceedings of the ACM Lisp and Functional Programing Conference will keep you busy for a while.
Efficient implementation of first-class activation records revolves around a few decisions. One is whether or not to use the hardware stack at all. Some efficient implementations use the stack and copy to/from the heap as needed. Others use the heap solely. Efficiency also becomes intertwined with interoperability with "C" and so-called "native code".
These choices have more to do with first-class continuations and languages like Smalltalk that promote activation records as first-class objects. If you go back and look at MIT Scheme and work by Guillermo Rozas, they paid a lot of attention to providing features like continuations and first-class top-level environments without _always_ paying the price.
The more common problem of allocating heap for first-class lexical environments is probably even less conducive to hardware-based solutions. A naive compiler (the most naive compiler is a simple interpreter) will allocate a lot of heap and generate a lot of garbage. So part of the solution is how efficiently short-lived heap allocations can be collected. The more complicated compiler problem is analyzing the code to determine how to reduce the amount or frequency of allocated heap. Based on determining which closures are "upward", what lexical state must be captured, and which closures share some or all of that lexical state, a compiler can very smartly move state capture up or down the lexical scope.
For example if closure C1 captures variables V1, V2, and V3, and in the same scope closure C2 captures just V2, then C1 and C2 need to refer to the same "instance" of V2. But maybe V2 is bound several scopes "up" from V1 and V3. The compiler may choose to heap allocate space for V1, V2, and V3 at the point where V2 becomes bound. The C2's code is generated to reference V2 at some offset from the start of this allocation. C1 references all three slots.
And that's the simplest case I could write about. There are other problems that I've not thought about for at least 15 years. My main point is that none of this "professionalism" is new. Many problems new implementers will encounter have a long history of solutions that are likely to be sufficient and, minimally, good starting points. All of the software solutions could show up within a year, where hardware solutions would not show up for five if ever.
The hardware instructions for all of this are fairly basic: incrementing pointers, relative addressing, short jumps. Not much more than that. The problem is how to do as little of all that as possible by walking a lot of tree stuff at compile-time, and leaving a marker here or there at run-time.
In addition to diving into the literature, I would recommend studying, if not using directly as a "common language compiler and run-time" the Gambit Scheme compiler and run-time. Gambit is the system to beat for efficiency, if it is not going to be your system to utilize as a "back-end".
In a recent comment here Dan Creswell refers to an algorithm for taking a global snapshot across a distributed message system...
...if our snapshot could just capture the "after" state, then we'd be done. However, we can't do that either because we're not allowed to stop the other messages flowing through the system after we take the local snapshot at a node. Therefore, by the time all nodes take their local snapshots, the global system state may have changed.From an interesting-looking course in distributed systems at Washington University, St. Louis.So, we define a recent and consistent global state as a global state that "could have occurred" between the "before" state and the "after" state. In other words, consider the sequence S of communication events that occurs in the system between the "before" and the "after" state. A recent and consistent global state X is reachable from the "before" state by some subsequence of the events in C. Furthermore, the "after" state is reachable from the state X by the remaining events in C. Notice that this global state didn't necessarily occur at any point in real time, but it "could have occured" between the "before" and "after" states using the same sequence of communication events.
Global snapshots are useful in a wide variety of distributed applications. One application is in distributed databases, for instance a group of bank branches. Another use is deadlock detection: a global snapshot can be examined to see if there has been any progress made by the algorithm. Termination of a distributed algorithm can detected in the same way.
From the EFF deeplinks blog...
Yesterday, in the Viacom v. Google litigation, the federal court for the Southern District of New York ordered Google to produce to Viacom (over Google's objections):Dang. Wish I hadn't watched so much Rick Astley. I hope Google tells the judge, "Never gonna give you up..."all data from the Logging database concerning each time a YouTube video has been viewed on the YouTube website or through embedding on a third-party website...for each instance a video is watched, the unique “login ID” of the user who watched it, the time when the user started to watch the video, the internet protocol address other devices connected to the internet use to identify the user’s computer (“IP address”), and the identifier for the video.
...
Google correctly argued that “the data should not be disclosed because of the users’ privacy concerns,” citing the VPPA, 18 U.S.C. § 2710. However, the Court dismissed this argument with no analysis, stating “defendants cite no authority barring them from disclosing such information in civil discovery proceedings, and their privacy concerns are speculative.”

James Robertson observes OnStar, the Pentagon, and your local transit authority losing control over their control freakishness...
This is like DRM, but with extra stupidity added in.Because I am _real_ worried I might end up in Speed 3.
The problem we are discussing is processes B, C, D hold information X, Y, Z respectively; process A wants a coherent snapshot of X, Y,Z.Yes, the problem seems simple yet subtle. The downside is there are many unwritten constraints (or not) on any specific problem that could lead the solution alternatives one way or another. Unless you want to really dig into those, then the cost/benefit of one solution or another could be more or less off.There are actually two slightly different cases depending on A needs "X Y Z as of *now*" (A, B, C, and D must all synchronise), or A needs "X Y Z as of *some* time in the recent past" (B, C, and D must all synchronise but can then send the information to A without waiting for A to receive it).
I like this problem because it is simple yet subtle. One way that it is subtle is that in "multithread" programming most people STILL think in terms of a single absolute time shared by all threads. (After all, there _is_ such a thing, the system clock. And yes, it's not exactly true, but it's close enough to make people _think_ it's true.) But when you start thinking about Erlang and especially *distributed* Erlang, you start realising that "now" is a pretty fuzzy concept.
e.g. why not coordinate through an in-memory database? This could be reasonable, or not. We don't know enough.
Why not schedule the source processes to send a message on a periodic or scheduled basis? This could be reasonable, or not, and cut down the message traffic, which seemed to be a concern.
Why is sending fewer than N messages a concern? Why does one process have to collect the information? How much information? How tight is the deadline? Is "now" an actual timestamp or just some unknown point in time that a request has been received? How close to "now" do the other "nows" have to be with respect to each other? Can you widen that window if it would decrease the effort to build?
If synchronization across the processes is needed then is an "eventually consistent" approach reasonable if it lowers the effort to build?
Interesting stuff, but challenging to talk about in when the details are too abstract.
As long as I'm writing down my thoughts on this trip: I've been in two hotels in Belfast, the Hilton and the Radisson. Both are nice, close to the city center, and on the water.
They both have internet frustrations: neither have wireless in the rooms; the Hilton charges for wired internet in the rooms at ₤15 per 24 hours! When you pay that fee then they also throw in wireless _in the lobby_! Well, it's BT and the voucher is good for any BT provider in that 24 hour period. I found BT is the provider around some nearby coffee shops.
The Radisson at least provides free, but wired, internet. The problem then is the MacBook's adapter for UK plugs do not fit in the limited space above the immovable desk provided in the room! The nearest outlet that provides enough clearance for the adapter is across the room on the other side of the bed. If I had a 25' extension cord for either electricity or the internet, then this might be less frustrating.
(Let me update this with a warning: if you intend to use the internets with any expectation of getting bits back to your laptop, avoid the Radisson altogether. Band-width-wise this turned out to be simply unusable for long stretches.)
And so on to coffee: Caffe Nero is the best I've found in the city center so far, and the best I've found anywhere for a large chain. http://www.caffenero.com/
