this is pretty wow to me!!
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
...is pretty important, and you should refactor when needed if only just for that. It'll spread all over rest of the code in many ways, in good ways.
Exactly, and that good way is reliability which is something I observe the study doesn't measure so whilst it's good to challenge the current wisdom, there seems to be a few holes here.
First up I don't think 4500 lines of code is a good was to asses the interaction complexity of applications where the codebase exceeds 10 or 20 times that number. Second I may write a functional prototype of code knowing full well that I or someone else will refactor later when we have a better idea of how things are functioning.
Unexpected failure modes are going to exist in the software. The whole point of doing things the 'Agile' way is to provide incremental improvement so things get better. The paper talks of XP but what if you are using DSDM instead of programming pairs, in that case you are *expecting* to refactor often as you explain the domain or new concepts are introduced. That's not scope creep, it's being honest and admitting you don't know everything.
In my experiences the most powerful concept is the vocabulary you build as you begin to understand the domain better. I've found refactoring is the opportunity to 'put things in the right place' to define the vocabulary which makes things easier on myself and my colleagues a year or two later when someone asks if they can have this extra feature. Sure we should be using certain design patterns when implementing code from the beginning however I'm certain I'm not alone in confronting a codebase and wondering why certain methods are implemented in the controller instead of an information expert and spending the next week refactoring to avoid peoples heads exploding when methods are duplicated...but they don't work the same.
that's my 2 cents...
Accept this, as you have uncovered something they didn't know and can potentially damage them.
I did this with a government tax office and tried to alert them by calling the very number they advertised to handle this sort of issue. The response went like this:
- Yeah there is a number you can call for this
- There is a what in our what?
- please provide you contact details
The problem is, you want to help them and all they can see is 'random person the phone saying we have a problem' so it is easier to solve you. If the company is responsible enough to have a CERT team and a reporting mechanism you may stand a chance but it is more likely you will draw their ire because you can hurt the companies reputation.
If you can't change institutions then you should consider establishing what their data privacy policies are, hire a lawyer and then frame legal action to protect your own data whilst seeking damages to the value of your life earnings for exposing you to identity theft and fraud. You should be pissed off.
They won' t play nice so neither should you. Seek legal advice about the possibility for damages because you have been exposed to fraud. Leave it to them to discover the mechanism, because if they are that bad there are probably more.
Huh, how brains work isn't interesting! Just because it's popular doesn't make convincing yourself that you're indifferent any cooler.
I suppose you are right and I don't mean it that way. The stuff about the brain interpreting colours is interesting but I find that when hollywood gets involved in geek stuff they make it lame and uninteresting.
Once you get to know radioactivity a bit better most people start to think it's cute and cuddly because it isn't all that radioactive. This is the phase many
/. posters seem to be in. Next thing some find out is that uranium is toxic, as a chemical.
That's about the time they discover there is a difference between radiation and radio isotopes, that one is an emission and the later is an emitter. After that they find out that particular radio isotopes appear to be particular micro-nutrients to metabolisms and bio-accumulate in the foodchain. After that they discover there is multiple pathways for radio-isotopes to get into the body via inhalation/food/water. Then they discover that once the radio isotope is in the human body the energetic alpha/beta/gamma emissions take about six years to gestate cancer in the body.
Chemical problems, not radioactive.
Indeed. Though the science I've been reading says that the effects of radiation emitted from DU are unclear on humans. I'll refer you to my earlier post for my summary of the science. Apologies for some of the language dealing with the troll.
The type of radioactivity in nukes is not relevant if you're not busy getting the mass to critical. The DU in Iraq is spread over a large surface area. It's nowhere near going critical.
DU has an unusual property where it has spontaneous fission and its energetic emissions jump from 4 to 240Mev (I think its the alpha emissions) whilst it decays. However that is not the point I was trying to make.
Ergo the radiation source of a nuclear bomb is not relevant to the discussion.
The point I am trying to make is not the source of radiation but a source of radio isotopes. That a nuclear bomb lets its energy out all at once and leaves much less than the original mass (~50Kg) as fall-out in the form of radio-isotopes.
In comparison with DU of which there is almost 2 tons spread around the country as a ceramic aerosol.
The world is a playground and the US is the strongest kid.
Deep down Americans are also just people. I don't believe that American citizens would allow this behavior to continue if they understood the consequences would attach them to such shame.
Why do artists expect to be paid at all for recordings of their music?
For the same reason that anyone expects to get paid for their work. If a software house sells a license to a compiled version of their software, they expect to get paid. In the same way musicians should be paid for the music they record and *render* through a production process. The tracking, mixing, production and mastering of music is a very expensive time consuming process, even today. It used to be more so but now it's at least accessible and roughly the same effort as producing software.
The only difference is that musicians aren't seeking to engage in a contract with the listener because they want to listen. For a similar piece of software there are terms and conditions for you to be able to pay to use the result of the software developers performance. Why is music any different?
For a very brief period in history, making money off of recordings was made possible by a coincidental combination of technology and artificial scarcity caused by the cumbersome nature of physical media.
The process of recording the music is demanding. Just because the cumbersome media is gone doesn't mean the cumbersome production process is gone and someone has to pay for that. It was that delivery mechanism that enabled the music industry to be created. Now its relationship to the artist is parasitic.
The scarcity now, is music that is worth paying for and, that's why mp3s are good advertising. Part of the confusion is the industry has moved on from analogue production and distribution process to a new business model of digital production and distribution. As many in IT have said, the music industry is a failing business model that treats it's customers like thieves and it's talent like slaves.
Musicians and IT folk have a lot in common, many do IT because they love the work. The music industry would have you believe that they should profit on the rescue of that production system or that software you wrote because you love it to do it. They would have you believe that they own the copyright on the application you developed and are entitled to the profits of the software business you built.
Before the advent of physical recordings, musicians had to make money by performing.
This is the 21st century, why isn't a recorded work a performance?
I can most certainly assure you that when my friends record we are seeking a performance that is as close to perfect as we can possibly get. It's not just a performance, it's THE performance. However most people haven't been through a recording session, actually most musicians haven't so they can't tell you what it's like. The ones that can, without cracking under the pressure whilst producing a performance good enough to be recorded, mixed, produced and mastered deserve to be paid for it because it is really hard work. Much like any Agile software project.
The only difference is a software developer doesn't pay $50,000 for the privilege of working an agile project, to work harder than anyone does in their day job to produce a recording that most people might not pay for however, that is what musicians are being asked to do.
Like any other business, the musician takes a risk to build a music business out of a relationship with an audience. Why is that any different from any other business who has product to move trying to earn a return on their investment in a project?
After the advent of digital recordings, musicians will once again have to make money by performing.
Why? The logistics of live performance is another cost burden that should be offset by a bands music distribution business. Don't forget they have to pay to lug tons of equipment, hire venues, crew, security, accommodation, flights, airports, marketing so you can have an experience. So just how much are you prepared to pay for a concert ticket? If there is no profit from the business of producing music then why would any sane person want to tour a band, often for years? Performances where the artists are so exhausted from grueling tours and living in hotel rooms that it's little wonder they have to be drug addict to endure it, to come out in debt?
This is not an incentive for good musicians to make good music.
Anything else will prove to have been historically anomalous.
The distribution mechanism to get music performance out there and it isn't going away. So I would argue that the artist making money from live performances is what is historically anomalous. The only question is will the distribution mechanism evolve?
Making and distributing recordings will still be in artists' interest, because they will serve as a way to generate demand for performances.
The cashflow constraints imposed by the upfront costs will ensure this is not a viable business model for any professional musician.
That is, recordings will become a form of advertising, which will be distributed for all intents and purposes for free, or even at the expense of artists.
For a distribution of a FM radio quality MP3 piece of music this is where I would agree. If that creates demand for any of the other higher resolution performances that renders THE performance closer to you, so that everytime you listen you hear a nuance you never noticed before, and enhances your life, then send the money to the artist who created the music, not to the record company that is ripping them off.
Art, especially music, is works for sale and will probably cost you less than a meal at a cafe, however no one expect the chef to buy, prepare and present all of the ingredients for free.
Can we quit wringing our hands about this now? Art will survive just fine.
Sure, it just won't be very good. Art will survive, artists my have a difficult time though.
Uranium is a heavy metal. Don't ingest those.
Friend, you say that as if these people have a choice. They don't. It burns at 3000-6000 degrees and oxidizes into an insoluble ceramic aerosol. As an aerosol it is in their air and it is in their drinking water. How do you suggest they avoid ingesting them?
Also a heavy metal. Nothing to do with radioactivity,
Yes, others have pointed that out. However you also said the scare-mongering over depleted uranium being somehow seen as more toxic than lead when its toxicity is still being evaluated in veterans and proving to be quite a serious issue for those exposed to it. So whilst your claim of no one cares about the uranium in granite countertops might be true I'm sure people would feel differently about it being in their air and water supply. Wouldn't you?
I'm sure this is one of the reasons the UN does not sanction their use.
because U238 isn't meaningfully radioactive.
Well I checked this and the science I read doesn't say anything about 'meaningfully radioactive', it says that the effects of U238 radioactivity as an emitter in the body are unclear and there hasn't been a large enough sample size of human beings exposed to U238 to understand the effects it has, on humans.
And to what isn't U238 'meaningfully' radioactive to? How do you know? Did you check the evidence? Because I did.
In the independent research with the most citations it seems that one of the cruelest deception played on the veterans is that uncovering *which* of the symptoms are caused by DU because they were also exposed to other heavy metals in pesticides and herbicides; in vaccines, including anthrax and botulinum toxin; in nerve agents: sari n, cyc losari n, tab un, som an, VX, multip le se ven, and no vac huks (nov ich oks); and in chemicals released from the Kamasiyah toxic chemical depot, which was destroyed by bombing and also subjected to petroleum products from the oil well fires.
So what has this got to do with u283 radiation? It turns out that because veterans were exposed to so many sources of heavy metal toxins it is preventing legal recognition of the harm caused by radiation, not that it isn't 'meaningfully radioactive'. A particularly salient and sobering paragraph from that paper:
Influential papers by physicists and several semi-official governmental organizations have attempted to eliminate DU from consideration by just such analyses (4â"8). These studies are not really independent, since each follows the guidelines, methodology, and risk estimates recommended by the International Commission on Radiological Protection (ICRP) (9).
As usual, I'll do the thinking here and join the dots to make it easier to understand the ramifications. As a final act of contemptuous betrayal of the soldiers what the ICRP was attempting to do was set up a research framework that led to the conclusion that the veterans suffering was all in their head. This is news to me too, even I didn't think the Nuclear Industry was that fucking despicable.
That is where your 'claim' that du is not 'meaningfully radioactive' comes from, so perhaps you should check the papers you read for ICRP influence.
How incredibly fortunate for us then, to have such a large sample size to study over the coming years in the populations of Kosovo, Iraq and Afghanistan and establish what the true radiological effect of depleted uranium is on a population.
No, I'm not going to teach you basic science. This is
/., you're expect to do that work yourself.
That sounds like usual cop out for those suffering the effects of of social proof not being able to challenge their belief system with any evidence. I present the science, you say its is bogus, you refuse to present any of your own and then, you insult me for doing so. Same old story.
However the science isn't the only thing you have to study. The legislation, Insurance arrangements, funding bills, mining, operating procedures of the plants, the way regulatory boards interact, reactor decommissioning, spent fuel containment, net energy return, this list goes on. Over the years I have amassed a significant library of information from doing exactly that work, it is quite a fascinatingly complex industry.
Fortunately for you, you only have to look at my previous post that references the US Library of Medicine information on how DU deposits in the body. If you understand the 'basic science' of how radioisotopes analogue nutrients in the metabolism then it will make sense.
If you don't you may wish to consult the work on how the weak beta emitter tritium effects transgenic disease in the human genome precisely *because* it is a weak emitter and the radiation is absorbed in the body from the tritium that tends to accumulate in stomach fat near the reproductive organs.
It was a common myth that the weak beta emission from tritium was also harmless. As it turns out it is harmful - to the next generation of those exposed, i.e. their children.
So the jury is still out on the effects of radioactive uranium compounds like U-238 an alpha emitter with rare spontaneous fission that undergoes 12.4 atomic transformations (submicroscopic explosions) every second, each giving off one alpha particle with energy between 4.15 and 4.2 MeV (million electron volts) in random directions, that when it decays by spontaneous fission releases approximately 40 times more energy than in nuclear decay, will do to DNA that only requires 10 electron volts to break, but I doubt the news is good.
It is certainly not something I'd like hanging around in my testes. Would you?
You're scare-mongering about an imaginary boogieman and need to be shunned from polite conversation,
You haven't provided a good example of polite conversation only moral superiority and dogmatic skepticism.
Maybe I'm wrong about veteran suffering toxicity over radiation poisoning however I doubt it. I just think it hasn't been identified yet. You think it is less toxic than lead and there are no effects from the radiation. I think that there is an effect from the toxicity and a subsequent transgenic affect caused by the radiations of U238 being absorbed in the human body that affects the offspring of those exposed.
Considering the models are only for death from cancer under ideal circumstances and not reproductive damage then it would seem it might be a worthwhile place for investigation.
Frankly, I can't see how anyone can support these weapons considering the suffering they impose. You have to be specially qualified to handle it and isolate it from the environment in the US so why is it ok to spread it elsewhere?
just like the anti-Vaxxers, the anti-GMO crowd, the "no irradiated food" crowd and the rest of them.
Just the same way I might put you in with evengelical christian or extremist muslims who will scream and abuse you for questioning their god. I'm open to having my position challenged when presented with the right information but that is not what you have been able to achieve here.
I do feel a bit foolish for upmodding you in the past though, for subjects we agree on and hope you are able to return to form soon. I find the cuntishness disappointing, a little tedious and juvenile. If you have some useful information to share we may be able to have a more civilized conversation.
Depleted uranium is not meaningfully radioactive.
First of all we are talking about depleted uranium's behavior as a radio isotope once its absorbed in the body, not the radiation it emits when it is outside the body - where it is harmless.
Not to mention those "on the receiving end" of a 10 kg projectile travelling at ~1000 meters per second don't suffer for long at all. When you start comparing bullets to nuclear bombs, you should really stop and realize you don't know what the fuck you're talking about.
Once the projectile has hit its target (or not) the du doesn't cease to exist. It is smashed and burned into varying size chunks of du all the way down to dust. So those targeted don't suffer for very long however those who breath in the dust do, including those who fire the weapons. I could say the same for your discussion of radiation vs radionuclide, however I choose to politely point out the facts, rather than launch into a rant.
Science more; don't come back till you do.
Ok, There is plenty of science. It is a commonly held myth that because du is harmless outside the body, it is harmless *inside* the body but it isn't.
I took this from the U.S Library of Medicine describing the effects of radionuclides in the body and it applies to a range of radionuclides, including u-238. From my understanding the main vector for absorbing u238 is inhalation, specifically uranium oxide however there are others. Only 10 electron volts of energy is required to break DNA or other molecules in the body. U238 is a alpha particle emitter of 4.2 million electron volts (MeV) per particle there is very little doubt as to the damage it does:
Systemic contamination will occur following ingestion, inhalation, skin absorption, or wound contamination of radioactive material. Following absorption, a radionuclide crosses capillary membranes through passive and active diffusion mechanisms and then is distributed throughout the body. Rate of distribution to each organ is dependent on organ metabolism, ease of chemical transport, and the affinity of the radionuclide for chemicals within the organ. The organs with the highest capacities for binding radionuclides are the liver, kidney, adipose tissue, and bone due to their high protein and lipid makeup. Each radionuclide has a unique half-life, with half-lives ranging from extremely short (fraction of a second) to millions of years. Samples of some radionuclides and their half-lives are: Tc-99m: 6 hours; I-131: 8.05 days; Co-60: 5.26 years; Sr-90: 28.1 years; Pu-239: 24,400 years; U-238: 4,150,000,000 years.
That makes the rest of your screed lies, bullshit, and stupidity. you should really stop and realize you don't know what the fuck you're talking about. You're an embarrassment to Slashdot, and that's a really low bar.
I was polite to you yet you feel perfectly justified in being a cunt to me. I just thought you didn't know and it was a difference of opinion. I've come to expect this as a fairly typical response from someone without much in the way of fact available to counter my arguments and they just attack me instead. If you can't back up what you say with fact, or change my mind, then why be a cunt to me instead?
Especially the scare-mongering over depleted uranium being somehow seen as more toxic than lead is entirely political theater ungrounded in any science.
As a weapon depleted uranium is one of the most insidious and makes landmines look positively benign in comparison. It may be ok when used in crockery or bench tops when kept sealed up however when it is fired from a tank its pyrophoric properties make it particulate in the environment and it becomes a serious threat.
Veterans of both gulf wars suffering 'Gulf War Syndrome' are, in reality, suffering from inhaling radioisotopes, i.e. radiation poisoning. A 1998 report by the U.S. Agency for Toxic Substances confirms that inhaling DU causes symptoms identical to those claimed by many sick vets with Gulf War Syndrome. So they may not be casualties of the war in Iraq, but they suffer for the rest of their lives when they get home due to their own government's policy to deploy du weapons, which is a war crime under UN conventions. That's the effect on the soldiers just for firing the weapons.
However the people on the receiving end of the weapons will suffer for much longer. That is because it is not immediately toxic to full grown adults who ingest it, only to their children. Since du's half life is measured in billions of years Iraq and Afghanistan will suffer these deformities for all subsequent generations. So will Veteran's families.
For a comparison, about 50 kilograms of uranium were used to bomb Japan and over one thousand tons of DU in Iraq. This is how nuclear waste is being used and what a 'dirty' nuclear war looks like. I don't think the claim that there is no grounding in science has a basis however the effects are plain to see. I agree that it is political theater, based on concealing and deceiving people into what is being done in their name.
