I don't know about kosher, but abs is not differentiable at zero, which may or may not be an issue. In terms of what you're looking for, -8-(-2) = -6.

Re: [FRIAM] Stephen Hawkings final theory
As a longtime proponent of the idea that physics is the result of
evolution, I was surprised that Hawking might also have thought so.
For me, John Wheeler's approach ("particpatory universe") is perhaps
the most canonical, with Lee Smolin's "black holes giving birth to new
universes with their own black holes" being an interesting variant.

ISTM, cell errors occur all the time, transistors stop working, maybe zapped by cosmic rays, or whatever. For a while, redundancy keeps the whole thing working - error correction algorithms fix failed bits, sometimes with a message in the system log about the fix, then some errors fail to be fixed, which leads to data being corrupted, and then finally the OS fails to mount the drive. I've had some success where the drive was a boot drive and the error was in system libraries prevented the drive from booting, but could be taken out and mounted in another system, enabling extracting the data. Even if the drive cannot be mounted, one can often extract the data on the system by skipping over the bad blocks. But it is very time-consuming, so only worthwhile if the data is a) very valuable, b) no backups exist elsewhere and c) plain text, as you will need to pour through reams of gibberish, looking for the bit of plain text data of interest. Actually, now I remember, there is some software that sniffs out common file types, eg images. I had to do that once when I lost nearly a month's worth of photos of my wife's due to a fat-fingered command typed in the wrong directory. It required sifting through around 100,000 images, looking for the photos in question. I got quite good at doing this efficiently, but it still took about 3 weeks of fairly sustained activity. -- -------- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders hpco...@hpcoders.com.au http://www.hpcoders.com.au - . -..-. . -. -.. -..-. .. ... -..-. . .-. .

I managed to get a replacement for that by sending the original back to Taiwan. But had to buy a replacement anyway (newer NVMe technology, so quite a performance bump), as I couldn't wait for them to post back the replacement, and that replacement is still going strong. I have also had multiple spinning rust disks die on me over the years, sometimes with a loud clunk and a wisp of smoke. But nothing in the last decade or so, so maybe HDD has become super reliable. In each an every case, I buy a new disk, restore from backups and continue trucking. You do do backups don't you? I have sometimes recovered failing HDDs by doing something along the lines of (on Linux) dd if=/dev/sda of=/dev/sda where sda is the name of you hard disk. This works by forcing the disk to use some spare blocks, mapping the old bad blocks to the fresh ones. Somewhat less successful for SSDs, though, as I suspect the filesystems automatically do that now under the guise of "wear levelling" Can't comment what you'd do with Windows - probably just download a live Linux distro, and use Linux files system tools is what I'd do. -- ---- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders hpco...@hpcoders.com.au http://www.hpcoders.com.au - . -..-. . -. -.. -..-. .. ... -..-. . .-. .

Literate programming is alive and well in modern software engineering - it just isn't called that. Knuth's tools which involved a special input language, a tool for converting that to compileable Pascal and Latex for producing humane readable printouts of the code were fantastic for the 1980s, but are rather dated for current software development requirements. In C++, one uses a tool called Doxygen, which parses standard C++ code, and produces HTML, Latex and other possibilities. The "dot" network graphics tool is used to produce interactive UML diagrams of the class structures, and source code is annotate with hyperlinks allowing you to click on (say) a variable name, to find out what type it is, where it is defined and so on. Plus, there is a huge amount of doxygen markup features available, allowing things like embedded LaTeX equations, or adding in crafted HTML links and so on. In short it does everything Knuth's web tool did, and more, without the need to write in an idiosyncratic source language. When I come across a piece of unfamiliar code, the _first_ thing I do is run doxygen on it, and then start reading the code using a web browser. People are sometimes amazed at how quickly I find my way around a new code base - when that happens, I let them in on my superpower, ie doxygen. Doxygen handles a number of programming environments, Java, C#, Fortran even, though not Python nor Javascript alas. Other environments have similar tools, of greater or lesser power: eg Java has Javadoc (which is broadly compatible with Doxygen, in fact). Knuth should be commended for being 30 years ahead of his time with literate programming, and should be glad the industry does finally "get it", even if his contribution is largely forgotten, and not acknowledged by the hordes of software engineers currently practising. -- ---- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders hpco...@hpcoders.com.au http://www.hpcoders.com.au - . -..-. . -. -.. -..-. .. ... -..-. . .-. .

It doesn't work well at any point. Basically, the name could be lying, for example if the implementation has been changed, but the variable name not. Therefore, if you need to know the type of something, then you need to look it up (modern IDEs make this pretty easy), not assume that the variable name tells you anything about it's type. Also, there are some many variants of "Hungarian", it gets pretty silly after a while.

Re: [FRIAM] GPT-3 and the chinese room
As I noted on the slashdot post, I was really surprised at the number of trainable parameters. 175 billion. Wow! The trainable parameters in an ANN is basically just the synapses, so this is actually a human brain scale ANN (I think I read elsewhere this model is an ANN), as the human brain is estimated to have some 100 billion synapses. I remember the Singulatarian guys predicting human scale AIs by 2020, based on Moore's law extrapolation. In a sense they're right. Clearly, it is not human scale competence yet, and probably won't be for a while, but it is coming. Remember also that it also takes 20 years plus to train a human-scale AI to full human-scale competence - we'll see some short cuts, of course, and continuing technological improvements in hardware. What's the likelihood of a Singularity by mid-century (30 years from now)?

Re: [FRIAM] Book publishing advice needed
My own experience of IP policy by a university was when my institution decided in the early noughties to require all staff to sign an IP legal agreement. I had been working there some 8 years by this point. I looked over the legal agreement, objected to a couple of clauses, and proposed amendments back to the uni IP lawyer, just like I've done with IP agreements in subsequent roles I've had. I never heard a thing back from the lawyer - result was I never signed the damned thing, so wasn't bound by its provisions. I ended up with a much more rights than if the uni had agreed to my amendments in the first place! -- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders hpco...@hpcoders.com.au http://www.hpcoders.com.au - . -..-. . -. -.. -..-. .. ... -..-. . .-. .

Leave a $100 bill on a park bench. What do you predict the next person to sit at that seat will do? Yes - someone you know well will be more predictable - my wife says so! I might also predict that if I disturb a magpie's nest, the bird will attack me. Also humans have the ability to reason what others predict they might do (3rd order reasoning), and deliberately do a contrary thing if that games the interaction. Not many other species have that ability (some other great apes have been shown to reason that way, IIRC, but that's about it). But humans are also capable of seeing through that sort of deceit too, via 4th order reasoning, but that recursive capability maxes out at 5th order IIUC. I would say most humans are actually quite predictable most of the time. But some are distinctly less so, and quite possibly successful as a result. Donald Trump is probably like this. He comes up with a lot of crazy stuff, so it's really hard to figure out what he's thinking. > > We also haven't evolved the ability to "put ourselves in somebody else's > skin". > It is not impossible, but can be very difficult and requires detailed > knowledge > and imagination.

Re: [FRIAM] God
Hi Nick - finally took a look at your paper. I didn't read it to the nth detail, but from what I understand, your scepticism about "ejective anthropmorphism" (nice term by the way) stands on two legs: 1) What exactly is priveleged about introspection? 2) That the process of ejective anthropomorphism starts from an identity between the target behaviour and the observers behaviour, which is structy false. The example being given of a dog scratching at a door to get in. In response, I would say there is plenty of privelege in introspection. For example, proprioception is entirely priveleged - that information is simply now available to external observers. In terms of the identity of target and observer behaviour, it doesn't need to be identical, but it does need to be analogical. The most important application of this skill is prediction of what other human beings do. People aren't the same, but they are similar - and human society functions because we can predict to some extent what other people are likely to do. I believe this is why self-awareness evoved in the first place. Something similar may have evolved in dogs, which are social pack animals. We have also evolved the ability to "put ourselves in somebody else's skin", taking into account the obvious external differences. So we can imagine being a dog, and wanting to get through a door, what would we do. We know we cannot stand up, and turn the door knob, because we don't have hands, so what would we do, given we only have paws. Scratching behaviour does seem a likely behaviour then. That, then is analogical. So, I'm not exactly convinced :). Cheers On Sun, May 24, 2020 at 04:32:05PM -0600, thompnicks...@gmail.com wrote: > Sorry Russ.

Re: [FRIAM] Science and Black Lives Matter
As a white caucasian male working in a STEM field, I could feel the same, as it seems to be dominated by Asian males (the two women in our group, including our boss who is a women, are both Asian too). I don't though, as they are all great guys, and good at their jobs. Hats off to the recruiters. In our country, it seems to be the asian-background community that has the right encouragement structure for their kids to do STEM subjects. But only for boys - it is still a big problem about the lack of girls going into these fields.

Re: [FRIAM] God
The theory which makes some sense to me is that we humans (as social creatures) have evolved to anthropomorphise. This make sense for dealing with other humans, who might be competitors, or compatriots. And the modelling makes use of a remarkable trick - observe one's own mind, and use those observations to model somebody else's mind. This explains why we have self-awareness, if not consciousness. The thing is, the same trick also works quite well with other animals, who may be predators or prey, irrespective of whether other species actually have minds or not. So it makes sense that when some relatively rare phenomenon occurs, perhaps a thunderstorm, that the alpha male stands up and makes threatening noises. And it seems to work when the thunder goes away eventually. And so the thunderstorm has been anthropomorphised. This got extended to other phenomenon, eg famines get blamed on angry gods who can be appeased by making the appropriate offerings. Eventually con-artists exploited this with ever more elaborate stories that leveraged this innate tendency to anthromorphise. I'm sure astrology started out as a cunning plan to garner research funds for early astonomers from ignorant kings. Like most evolutionary stories, this is a "just so" story. But I think it has a grain of truth.

Re: [FRIAM] sum of atomic spectra == 9000K black body?
I suspect the shape of the curve is due to adding up a whole bunch of unrelated things with some lower wavelength boundary, just like the "law of large numbers" theorem, that shows adding up random numbers gives a normal distribution (bell-shaped curve). The same might be said of the black body curve (although it has been ages since I've looked at the mathematics of that). The peak of the curve at 9000K is probably a coinicidence, although IIUC, the universe was constantly cooling from the first spit second, so is the point at which it was 9000K significant in any way? Anyway - meh - someone else can look into this. On Tue, May 12, 2020 at 05:59:11PM -0400, Roger Critchlow wrote: > Jon -- > > It's a mystery to me.

Re: [FRIAM] Coronavirus vs Flu
Flu is already pandemic. COVID-19 looks like it will go pandemic, but maybe quarantine will buy us enough time for vaccine. COVID-19 has twice the mortality of flu, but don't know how transmissible it is. I currently get a bad flu about once every 5 years, and even then I'm probably only confined to bed for a day or so. Must be hell for the more vulnerable amongst us though. So, no - I'm not overly afraid of it, but it does have an impact on everyday life (eg quarantine provisions are impacting this workshop I'm running right now).

As someone who graduated from being a "programmer" to a "software engineer" somewhere around 2008, I can testify there is a world of difference between the two. A programmer will happily churn out programs up to 1000 lines of code, and maybe manage a 10,000 loc program by dint of extreme hoeroic effort. Using software engineering techiniques, including object orientation, extensive regression testing, continuous integration, source code management and so on, a single programmer can easily manage a 10 Kloc program, and up to 100Kloc loc by dint of heroic effort (ie an order of magnitude more complex). A small team of 5 coders can perhaps manage a 1Mloc codebase (albeit probably not 10x as complex as the 100Kloc codebase in my experience), but requires much more intrateam communication, via daily standups etc. For larger projects eg the Linux kernel (ca 30Mloc), it is only feasible by being extremely modular, which cuts down on the amount of intrateam communicaton. Noone, not even Linus, has a clear picture of the whole. But none of these larger projects would be possible without the discipline of "software engineering". Whether "software engineering" is actually "engineering" or not is a pub argument, but it clearly works when applied pragmatically and not idealogically. If not "engineering", we would still need a name to cover the set of techniques that help tame complexity, and manage software development at scale. -- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders hpco...@hpcoders.com.au http://www.hpcoders.com.au FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com archives back to 2003: http://friam.471366.n2.nabble.com/ FRIAM-COMIC http://friam-comic.blogspot.com/ by Dr. Strangelove

It is sobering to think that all Oxygen in the air is of biogenic origin (some 22% of the air) and that at some point in the past, that oxygen was bound up in carbon dioxide. If we burnt all the carbon buried in the ground, we'd have no oxygen left. Clearly, we have to leave most of the fossil fuel in the ground.

BTW my grandfather actually knew him (by his real name Nevil Norway). Actually looking up Nevil's wikipedia entry, they probably were nearly neighbours. My grandfather lived just outside Pearcedale, and Nevil's last years were spent at Langwarrin, the next district to the North. They probably knew each other through the farming community, and both being ex-Poms. Back to the bushfires - these are like nothing anyone here has experienced before. Whilst we've had bad fires before, they've all been limited in both time and space. Bad for the people affected of course, but generally forgotten about by the general population within weeks. This is different. I would hazard a guess that more than 50% of the population is affected, either directly or indirectly by poor air quality. It has become a way of life to check the air quality app before venturing outside, whether to go to work, shopping or exercise. The smoke has even made its way across the Tasman and affected some New Zealand cities. The only thing comparable I think would be the 1997 Kalimantan fires in SE Asia. Of course this was predicted as a consequence of climate change, that we'd have increased drought and fires. And of course, our elected buffoons are cut from the same cloth as the ones you have in the US. Ten years ago, Australia had one of the first carbon taxes in the world. Not really significant economically, and unlikely to have much effect on fossil fuel use, but at least symbolically useful. That was torn up by the conservative government elected on a platform of "there is no climate change, burn baby burn". We've had a decade of head-in-the-sand politics, with the energy industry screaming for some policy certainty with respect to roll out of renewables and the like. Instead, we get the government pleading with coal fired power station operators to keep such stations open when the operators decided to end-of-life them. It's madness. And when given the clear choice between explicit policies to change the energy infrastructure, not open new coal mines and some other (fairly mild ISTM) tinkering around the edges of the tax system, and on the other side "we have no policies, but watch out for Bill shock" (yes the opposition leader was called Bill), people chose the "we have no policies" government. Elections these days (perhaps always were) simply a popularity contest, not a rational decision. What is really disgusting is that once back in power, the PM actively refused to meet with the fire chiefs back in April, who were warning him of a bad upcoming bushfire season. Well I guess the ostrich got his bum bitten by a lion. The silver lining in all of this is that these fires affected so much of the population, that that should fortify the PM to tell his rabid right wing to put a sock in it, and proceed to develop policies for how to deal with climate change. IMHO, the boat sailed 30 years ago for actually preventing climate change - the best we can do is mitigate or slow it down, and secondly adapt.

Well the examples I mentioned were all rewritten/refactored from a selfish need - I had inherited code that I had experienced as having high technical debt, requiring much more effort to modify for future needs than ought to be, and eventually persuaded my PM that fixing that debt was a good investment. Of course a piece of crap code that happens to work just fine, and doesn't need to be touched, I will leave that well alone, of if necessary, craft an interface that takes care of administrative needs (such as memory allocation and so on). I only refactor code that gets in the way of getting the job done.

Re: [FRIAM] IT is Not Sustainable
It's all about the LOC! Actually, I kind of agree - having worked on some MegaLOC codebases that functionally seemed to be no more complex than a 10KLOC project I'm involved in, the 10KLOC project is much more nimble - compile times are far less, making changes to the code easier and bugs less troublesome to winkle out. I've also refactored or rewritten pieces of code to slash the LOC by a factor of 3 or more for that particular section (eg 3KLOC -> 1KLOC) - but usually when bugs and problems kept on cropping up in that section. Even though the LOC is an entirely bogus measurement - if you paid a programmer by LOC, you'd get boilerplate and crappy comments. -- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders Visiting Senior Research Fellowhpco...@hpcoders.com.au Economics, Kingston University http://www.hpcoders.com.au FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com archives back to 2003: http://friam.471366.n2.nabble.com/ FRIAM-COMIC http://friam-comic.blogspot.com/ by Dr. Strangelove

You should only transfer that stuff. I have home areas (mounted under /home) that is backed up, scratch areas that is not backed up, and everything else just contains system software and applications. When commissioning a new machine, I could just copy the home areas, but usually also copy the scratch areas too, as this often contains most recently worked on stuff that I don't care particularly if they disappear (eg github projects), but save time and effort finding and downloading. I don't copy system stuff, but install everything as a I need it, mostly from the distro's repo, when I need it. This means that applications I used once and never used again don't get installed again. But this is a Linux computer, for Windows, it is a virtual machine, and I back up the entire machine, if only because it takes several days to set up a Windows machine. But I don't have any personally interesting stuff on the Windows machine, so I can recover in the event of it being hosed or virused anyway - the backup is just to save time.

I don't think levels are just figments of imagination. Compression algorithms replace explicit descriptions with generative algorithms (like procedures of functions) that when called with appropriate parameters reproduce the original data. These generative descriptions have a tree-like structure, which is exactly the heirarchical structure you're after. Obviously, there is no unique compression algorithm, nor even a unique best algorithm. But I suspect that the best compression algorithms will probably agree up to an isomorphism on the heirarchical structure for most compressible data sets (note that this is already a set of measure zero in the space of all data sets :).

The first result was an early one of Shannon's, who showed that adding a random oracle did not increase the set of functions that are computable. However, conversely, there appear to interesting results that indicate P=NP for random oracle machines.

But contrast this with physicalism, or eliminative materialism, which denies any sort of existence to those relations. But such a materialism is both monist and dualist and emergentist. Those relations emerge from the matter, and are the dual aspect. Think of graph vertices and edges as being dual objects mathematically. BTW - what we normally think of as matter (eg chairs, tables and so on) are really more about relationships between charges - ie electromagnetic fields.

Re: [FRIAM] Digital forensics?
Using Linux, you can just mount the Mac's hard drive, and use unix tools to investigate those files that were touched in the time span of interest. To be really sure, you should clone the drive first (eg using the Linux dd command) so that you don't accidently destroy any evidence in your poking around (you work with just the copy). As for the iPhone, I don't know how you would clone its storage, as it's locked down by Apple. Presumably, you would need to jail break the device first (potentially destroying the evidence you're looking for). But once you have cloned it, you can mount the storage on Linux as per usual - I believe iOS just uses the normal HDF+ file system that MacOSX uses.

Re: [FRIAM] Android phones
I've gone low end, around the USD 100 mark, since mobile phones are just a tool, not the focal centre of you life like it is for some folk (my laptop is more that thing). Being cheap means I don't worry too much if I lose it, or it meets an untimely end in say a swimming pool. In the last 8.5 years since I moved from Symbian to Android I've had one LG, two Samsungs and am now on a Xiaomi Redmi 5. The LG died with a faulty earphone jack (couldn't hear the person on the other end regardless of whether the earphone is being used), the two Samsungs died with charger circuit issues, but otherwise were fantastic phones for the approx 2 years they survived. The Redmi, which I've now had for 6 months has great specs, but the build quality is not so great. The screen is covered in cracks, and the buttons are starting to get difficult to press. Oh, well, you gets what you pay for, I suppose. By contrast, my wife used her iPhone 4s for about 6 years, with only one cracked screen needing to be replaced. Apple do have good build quality.

Hah - half way through writing this email, my finger accidently hit the power button, which is helpfully positioned right next to the delete key. One of the few design faults of my new laptop! Anyway, after a bit of googling, I have found the configuration setting to disable the power button (I only ever use it to hard power cycle via the 10 second press any way, which still works). So much more abbreviated response here: basically SATA interfaced SSDs are not that much faster than hard drives, no more than 2x when benchmarked, and making little practical difference to the performance of the computer. M2 SSDs OTOH seem more worth it. I had a Patreon Ignite 490GB job, which died just days before its 3 year warranty period expired. Patreon did honour the warranty, and did replace it, although it did involve sending the old SSD to Taiwan, so around a month all up for the replacement to arrive. In the meantime, I bought a Samsung 970 EVO, which is a faster technology called NVMe. So far so good, although I only have about 4 months on the clock. My replacement laptop which is only weeks old has a Western Digital Black NVMe SSD - and so far so good. Speaking of which, I swapped out the hard drive on my old laptop for a second hand SSD about 6 months ago. It was a SATA based drive, which had had a varied life under my care since mid-2014, but not a hard life. About 2 months ago, the SSD started dropping offline after about 15-30 minutes of use. Since the latop was nearly 9 years old it was time to upgrade. Not entirely sure if the SSD or the SATA subsystem of the laptop is at fault. No data got harmed... One final comment - avoid Btrfs like the plague. On the couple of occasions I forgot and accepted the default option of Btrfs on a machine with an SSD, the computer will work for a few hours (maybe even days), then suddenly the load average goes up to 20, and the computer becomes unresponsive. Some btrfs process is running, and it never stops - the only way of recovering is via a hard power cycle.

Re: [FRIAM] Experts explaining stuff at multiple levels of difficulty
Yeah, except there's a well-read interested-in-all-things-scientific 14 year old, and then there's my wife. I know who I'd rather explain things to :). Then there's my friend's book "Debunking Economics". I found it rather heavy going, because I had to figure out from the text what the actual mathematical equations were (at least its economics, not rocket science!). Some other people I spoke to found it to be the paragon of clarity, precisely because it contained no mathematical notation. Go figure.

Markus's original problem was that the restrictive nature of his client network was such that he couldn't distinguish between requests at layer 3 (TCP). You're right that layering the requests on a layer 4 protocol like http allows you to distinguish requests by inserting the distinguishing label in a field in http request header - eg the Host field, which can contain a domain name and a port. ISTM, it is not necessary for the domain inserted into the Host field to be resolvable - if it is, then just distinguish on the port part - so dynamic DNS is not necessary.

All these seem to be arguments against what I call OO purism. An OO
purist tends to see things in terms of UML diagrams, and a 1-1
relationship between the UML diagram and the code. This leads to
limited flexibility (ie code fragility), and to be quite frank, at
times confusing code.
For me the techniques of OOP (by which I mean attaching methods to a
collection of data, and only that) are simply tools in a
toolbox, amongst many others.
Inheritance is great for code reusability, composition much
less so (requiring much more error prone plumbing code). The isa
versus hasa distinction needn't apply, but can be useful for rasoning
or modelling, but not always.
(Dynamic) Polymorphism can be useful for
containers of similarly behaving things that have distinctly different
data structures. I tend to use generic programming and duck typing
otherwise.
Encapsulation is extremely important to maintain invariants
- where the state of two fields depend on each other, they should be
encapsulated to prevent their values getting out of sync. Otherwise,
it is generally more useful to expose members directly as public (a
bit more thought is required with APIs, of course). And don't get me
started on getters/setters. If an attribute has both a getter and
setter (particularly trivial ones), it is a code smell that it really
should be a public attribute. I have seen encapsulation taken to such
extremes that code becomes difficult to understand and debug.
And as for patterns, I have sympathy for the person who said that
patterns make up for deficiencies in a language. The classic example
might be the Singleton pattern making up for an absence of global
variables in Java. I haven't read the GoF book, but have seen some
disasterous applications of patterns to code, that obscure and
complexify things unnecessarily. Nevertheless, I do use some patterns
(that I don't believe are in the GoF book), particularly for
multithreading (cf active object), or my favourite the lazy
instantiator:
inline Foo& foo()
{
static Foo f;
return f;
}
This pattern (which is actually a kind of Singleton) is required to
get around C++'s link time ordering problem. You must make sure foo()
is called at least once before any multithreading is started though,
perhaps by setting a static variable in the main.cc file, otherwise
you end up with a race condition.

Re: [FRIAM] What is an object?
Not sure about "utility"/"tool", but an object is distinguished from a function by having state. Call an object's method, and the method's scope is populated by the object's data members, which of course, differ from object to object. By contrast a function either has no state (pure function), or its state is global (same for every function invocation).

I wasn't implying that. Given the undeniable success of GitHub in creating such a commons, recreating that same commons in the event of some corporate overlord (doesn't matter who) destroying it should not be difficult, and will be done. Particularly if someone has cloned a copy of GitHub's sourcecode, which seems likely. As per point 1, it will take 30 seconds to reattach your own code repository to the new commons. The biggest loss will be in abandonware - some itty bitty project code that someone dumped into Github and forgotten about, and then nobody cared for. Should we care for such projects?

These risks are real, eg Geocities, but can be mitigated. Git is a fully distibuted repository, so if GitHub were to disappear overnight, the repositories will exist with all the commit metadata on all the developer machines out there that have cloned the repositories. It is a simple exercise to populate a new Git repository with the contents of a locally cloned copy. As a result, I do not worry about the source code for the projects I'm involved in. My biggest worry is that the bugtracker data (called "issues" on Github) might disappear. For my own projects, I use SourceForge's tracker, which IMHO is slightly nicer, and for historical reasons, but the same risks exist. I have a python script that grabs the contents of all open tickets for a project on SF. The data is a bit scrambled, but at least it will be possible to reconstruct the tickets on a different system if required. It is also useful to get a local copy of open issues for when I'm working offline on my laptop.

The problem is that these days, the browser tries to _be_ the operating system. A bit like what people complained about emacs back in the day. Not sure there's much to be done about it, other than grumpy old men rants. If its really important to you, you'll need to buy yourself the same class of machine developers use, ie minimum 16GB memory 3+GHz multicore processor. Otherwise, you just have to kill off the browser every day or two (akin to doing the 3 fingered solute on good ol' DOS) to release the execessive amounts of memory.

Yes SVG and Canvas are HTML5 features that are very nifty. Canvas has an excellent Javascript API, comparable, though not identical, to the Cairo graphics library for C/C++.

I have been having a long debate with another philosopher friend of mine who essentially argues that Goedel's incompleteness theorem entails realism. For the purposes of our discussion, we define realism as being properties independent of observation, ie brute facts about the world, and anti-realism as the position that there are no such properties - every observed property must either come about through the process of observation, or be effectively random eg I speak English here,but there are other people who speak Chinese, and somewhere out in the Multiverse are people speaking any conceivable language, One may categorise realism as the position that some things are and other things aren't. Roughly as a result of that, I argue in my book Theory of Nothing that Everythingism (ie everything exists in a Multiverse) entails anti-realism, ie that laws of physics must be grounded in psychological laws, and vice-versa. As a consequence, discussions of ontology (what might be the real fabric of our existence) are pointless, as no empirical observation can reveal anything about it. Anyway, back to lurking...

Re: [FRIAM] How to install Windows on an external drive | TechConnect
For Linux, VirtualBox works a treat. I would say Windows 10 works better on Virtual Box than on real hardware, at least according to people I know who do the latter. NB Windows 10 has some known DHCP issues. I generally just end up configuring a manual IP on a private network or a NAT just to get around connectivity problems.

If they're able to determine the ground state from a n-body quantum state efficiently using a brain-like structure, then this strongly hints at that connection.

Obviously, you can exploit nonuniformity to provide a compression - eg the way that 'e' and 't' are represented by single . and - respectively provides a compression of random English language phrases.

Your question comes down to: given a set of statistical distributions
(ie models), which model best fits a given data source. In your case,
presumably you have two models - a uniform distribution and a normal
(or Poisson - they're two different distibutions resulting from
additive versus multiplicative processes respectively) distribution.
The paper to read on this topic is
@Article{Clauset-etal07,
author = {Aaron Clauset and Cosma R. Shalizi and Mark E. J. Newman},
title ={Power-law Distributions in Empirical Data},
journal = {SIAM Review},
volume = 51,
pages = {661-703},
year = 2009,
note = {arXiv:0706.1062}
}
Almost everyone doing work in Complex Systems theory with power laws
has been doing it wrong! The way it should be done is to compare a
metric called "likelihood" calculated over the data and a model, for
the different models in question.
I was scheduled to give a talk "Perils of Power Laws" at a local
Complex Systems conference in 2007. Originally, when I proposed the
topic, I planned to synthesise and collect some of my war stories
relating to power law problems - but a couple of months before the
conference, someone showed me Clauset's paper. I was so impressed by
it, not only superseding anything I could do on the timescale, but
also I felt was so important for my colleagues to know about that I
took the unprecedented step of presenting someone else's paper at the
conference. With full attribution, of course. I still feel it was the
most important paper in my field of 2007, and one of the most
important papers of this century. Even though it didn't officially get
published until 2009 :).
Nick's question is unrelated to the question of how to detect whether
a source is random or not. A non-uniform random source is one that can
be transformed into a uniform random source by a computable
transformation, so uniformity is not really a test of randomness.
Detecting whether a source is random or not is not a computational
feasible task. All one can do is prove that a given source is
non-random (by providing an effective generator of the data), but you
can never prove a source is truly random, except by exhaustive testing
of all Turing machines less than the data's complexity, which suffers
from combinatoric computational complexity.

Re: [FRIAM] weird malware
Mystery solved! It was all a bit more innocuous than it first appeared. There were two messages stuck in the inbox of my POP server, which because they had malformed return address could not be downloaded nor deleted from the pop server, so there they stayed, unread by anyone. Postfix was writing a message to the log complaining about the malformed address. I was able to web mail into the pop server directly, and after a bit of fiddling with the unfamiliar interface, managed to delete them They were just the usual run-of-the-mill Nigerian-style scam letters, nothing to be too worried about.

Re: [FRIAM] Document management
Obviously this a problem everwhere in the world. My experience in dealing with this is that a typical cubic meter of paperwork is 90% obsolete, and can be shredded at source. Tax documents need to be kept for only 5 years, memorabilia you aint going to need it, etc, etc. What really remains are a few certificates etc (as you mention), plus occasionally a gen in the form of a diary or unfinished manuscript by that forgotten uncle :). A recent example of sorting through my mother-in-laws stuff yielded very little that needed to be kept. As for tax related stuff, receipts, warrantees, instruction manuals, know your sunset dates, sort them into envelopes with a discard by date, and as you go, discard the stuff that has passed its discard by date. Seriously, it fits into one small small box (maybe 1/4 cubic meter). I am trying to deal with photos, and academic paper that were printed of yore, now. Of course the temptation is to actually try to read the stuff!

He picked it up and did quite a few things in it, as well as coding lego robots in Robo C later on, but didn't end up being a coder.

Haha - its the fundamental theorem of calculus. And if you try to differentiate a Riemann sum, the fundamental theorem is pretty obvious. Not sure that graphing it would be convincing, however, even though I'm generally a fan of pictures. -- -------- Dr Russell StandishPhone 0425 253119 (mobile) Principal, High Performance Coders Visiting Senior Research Fellowhpco...@hpcoders.com.au Economics, Kingston University http://www.hpcoders.com.au FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com

A bright 9yo should easily be able to handle the concept that letters can stand abstractly for a number. Lack of algebra prevent the ancient Greeks from getting calculus. I'd avoid trig, though, it's not necessary for getting the concepts of differentiation and integration (unless Norm Wildberger's approach helps?). Then once you have algebra to hand, you need to teach the concept of limits. eg If x->0 and y->0 twice as fast, what is the limit of y/x? The answer is 1/2, not 0/0. With limits and algebra on hand, you can tackle differentiation and integration of polynomial functions. If she's any good at computer programming (eg perhaps using Scratch or Alice*), then get her to write a program printing out the value of something like (x+1)/x as x->infinity. Its a really good way (IMHO) of grokking limits. Then you can write a program to estimate the area of some random shape by tiling it with rectangles and then letting the tile size go to zero. That will give an excellent introduction to integration. * It might be possible to use a spreadsheet for this as well, with the added advantage of being easily able to graph the results.

Which is why it is Linux for me. I also build my own machine, or use a custom box builder - buy the parts you need, have it delivered with those parts already assembled, then add you own bits. Main advantage is getting more powerful hardware for your money. Windows Xp => Windows 7 => Windows 10 seems to be definitely moving in the right direction, but even Windows 10 still feels clunky to me compared with Linux. Windows releases in between (Vista and 8) were definite missteps. Incidently, I run Windows 10 on a virtual machine which I found works pretty flawlessly. I've heard people have had some problems running it on real hardware, though. -- ---- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics hpco...@hpcoders.com.au University of New South Wales http://www.hpcoders.com.au FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com

Except that Airbus is actually French, but happens to be spelt the same way in English, so it naturally gets an anglicised pronunciation in English.
