    I'm guessing (without reading the paper), that the point of using dots is that the dots are not infinitely small, but rather have a small measureable size, and so the nearer dots are drawn larger, but that all dots are small enough that they don't tend to "hide" each other in the Z direction, but rather "pile up" a bit to make the piled up places darker.

    No. Having had a quick glance at the paper (available through the link to the renderer provided elsewhere), the techique centres around generating a number of points per voxel that varies according to the shading you want at that location in the image. Hence, the density of dots in any given region will vary in proportion to the "darkness" of the underlying data set in that region. The tricky part is working out the number/distribution of points that will produce a viewable image with all desired features highlighted, given that most images will be viewed at a resolution that would cause the object rendered to appear as a black smudge, even at a maximum point density of 1 point per voxel.

  3. Workman's lien and contracts for goods and service on Can Contractors File a Lien for Unpaid Work? · · Score: 2

    Standard disclaimer: you should really see a lawyer regarding your own particular circumstances. This isn't legal advice, just some general information you might be interested in.

    A workman's lien, as others have pointed out, is a proprietary right over an objet that you surrender to a workman for him/her to work on it. In a certain sense, the workman becomes the "owner" of the property you surrender (or, to put it another way, your title and interest in the property is burdened or encumbered by the lien) and the workman has the right to prevent you from taking back the property until you're paid the price of his or her work. It doesn't really apply in contracts for sale or construction of goods.

    In that case, different rules apply. In a contract for the sale of goods, title usually passes the moment the contract of sale is finalized, i.e. when vendor and purchaser agree that the sale should go ahead. If the purchaser goes bankrupt, then all creditors have rights against those goods as the purchaser's property, and the vendor simply has the status of an unsecured creditor through his unsecured right to payment

    The traditional way to get around this is the insertion of a clause into the contract to override the default position and stipulate that title only passes once payment has been made, and that up until that point the purchaser has "only" an unrestricted licence to use and convert the goods as s/he wishes. If the purchaser goes bankrupt, the vendor then has a property right in those goods (provided they're still capable of recovery) over and above the rights of other creditors. In the case of contracts for the production and sale of intellectual property, the default position would be governed by the provisions regarding ownership according to the circumstances when it is related. IIRC, US copyright law provides that copyright always vests with the author unless there is an express contractual term to the contrary. I am unaware of the position for patents, designs, or other forms of IP in the US.

    Bottom line, you should try to have a term included in your contract stipulating that assignment or exclusive licence in the copyright or other IP right will only transfer once you've received payment. That's likely to be difficult, as your employer is likely to be making regulard part payments (through your pay cheque) for your work, and doubtless is expecting to see something for it. Note that you may have trouble doing this retrospectively, especially if the person or compnay who's paying you is in trouble. That's called a voidable preference, and bankruptcy/insolvency law takes a dim view of such attempts of creditors to secure parts of a prospective bankrupt's assets for themselves when it becomes clear that the ship's going down.

    I just had a quick flick through the judgment as kindly linked to in Eggplant's post. The case was decided on common law grounds, the registrar considering the two torts of interference with business or trade interests (which isn't yet recognized in Australia) and interference with contractual relations. Defamation was knocked out by reference to a provision in the WA Criminal Code that bars accurate statements from being defamatory.

    Ditto

    Australia is a 'common law' country. A judgement in an Australian jurisdiction such as Western Australia would only ever been seen as 'persuasive precedence' in any jurisdiction besides WA.

    I would put a rider on that. Unlike the United States, the common law in Australia is unified: every state has the same common law. Every state in the US, on the other hand, has its own version of the common law as developed by that state's courts. This difference is a result of the expanded jurisdiction of the High Court of Australia as compared to the US Supreme Court. The High Court is a general court of appeal, having appellate jurisdiction over just about anything in addition to its original and appellate jurisdiction over constitutional and federal matters. The US Supreme Court only has jurisdiction over federal and constitutional matters, and only decides state cases as they conflict with some constitutional provision or principle. The creation of such an integrated judicature administering a single common law results in the courts of each state having a lot more respect for the judgments of courts in other states. However, this case wouldn't appear to establish any new rule or principle, so it can't be relied on as precedent for anything.

    Western Australia is one of 2 states in Australia who have a codified legal system. This means that the common law is generally superseded by specific coded laws.

    Really? I was aware that the criminal law of WA, as well as that of Queensland (my home state) and Tasmania, was codified, but that the rest of the common law has been either left intact or modified, not extinguished or supplanted, by statute.

    Finally, although I haven't seen the judgment, I would also add that in Australia costs usually follow the event (i.e. whoever loses generally has to pay the other side's costs as well as their own legal bills), so it's likely the plaintiffs would have had costs awarded against them.

    I had a chem lecturer who did just this very demonstration as a fun way of introducing emission spectra (pickles contain high quantities of sodium, making the pickle act like a sodium lamp). As the demo wore one the glow from the pickle decreased, presumably because some chemical change in the pickle wrought by having large quantites of current pumped through it tied up the sodium. To compensate, the lecturer cranked up the voltage on the power supply he was using, which worked fine until his hand slipped and he accidentally ramped the voltage all the way up to the supply's highest setting (240V IIRC).

    Needless to say, this was well in excess of the pickle's tolerances, and it exploded, showering fat orange sparks everywhere (nearly catching an unlucky student volunteer involved in the demo) and sending an almighty stink throughout the lecture theatre.

  10. Re:What is the basic philosophy behind EU patent l on Talk To a European Patent Examiner · · Score: 2

    I think I can partially answer this one. The important fact to note is that the European Patent Convention (the document constituting the EPO) isn't part of the body of treaty law comprising the EU. This creates some interesting problems, especially when the EU passes patent directives that could require member states to try and alter their obligations under the EPC (while all EU members are parties to the EPC, not all EPC parties are member states of the EU).

    The basic upshot of this is that there is no single European patent that can be overseen and enforced by a transnational judicial system (i.e. the European Court of Justice). Instead, the grant of a patent from the EPO is recognized and enforced by the domestic courts of each party to the EPC. Effectively, you get a "bundle" of national patents in countries with quite similar patents law (as the EPC requires).

    So, a general answer to your question would be: while there are many similarities in the way the EPC countries treat patents, there will be differences according to the system of law employed domestically by each country. So while the UK would have a similar approach to the US, the civil law countries on the European continent will have minor, but not insignificant, differences. Since I'm no expert on civil law, I can't give you any more information than that.

  13. Re:Jurisdictional issues on How Italian Police Shut Down U.S. Web Servers · · Score: 2

    There are three factors at work here:

    You forgot one: the type of relief being sought. Let's assume that a criminal action is brought for the production of material. Usually, the production of material must occur within jurisdiction for it to be an offence. However, there is nothing to prevent a nation enacting laws that have extra-territorial jurisdiction, and in some cases, this is quite legitimate. IIRC, the UK has laws against conspiracy to murder a British subject that have universal jurisdiction, i.e. it is illegal to conspire to kill a British subject anywhere in the world. This is completely in line with a sovereign nation's right to protect its own interests and that of its citizens. The only fundamental limit on such laws is that of enforcement: HM government can't send its law enforcement officials into another country to arrest a suspect without that country's permission. Therefore, if all you are doing is seeking to lay criminal charges, then jurisdiction isn't a problem provided the accused is within your territory and the necessary domestic legislative framework is in place.

    If what you are doing is seeking to take down material outside your territory, then things get more complex. According to your own laws, remote takedowns may be totally acceptable, in which case you can safely get away with it provided you're in your own territory. However, it may constitute unauthorized access by the laws of the country in which the material resides. This creates an interesting reciprocal lack of jurisdiction: the people maintaining the material locally can't pursue you in their domestic courts because you're outside their jurisdiction, but OTOH if those domestic maintainers decide to roll back your changes, there's nothing you can do because they're outside your jurisdiction.

    Common law countries such as the UK, US, Canada, Australia and NZ get around this by issuing court orders that bind the person who owns the content (they act in personam) rather than orders that authorize officials to affect the content or thing in question (orders that act in rem). In other words, the person who has control of the material is charged with taking it down themselves, so whether the material is within the jurisdiction of the court making the order or not is irrelevant. If the subject of the order refuses to comply, they're found in contempt and thrown into prison until they agree to comply (they may also have contempt charges levied against them on top of any other charges they may have to deal with).

    Bottom line: it's an unholy mess, and one of the reasons why countries are seeking harmonization of laws through such instruments as the Council of Europe's cyber-crime treaty. Whether this turns out to be a Good Thing or a Bad Thing remains to be seen. There is certainly a potential bleeding of draconian laws into the domestic legal systems of otherwise enlightened countries, but a lack of such an international framework will make a mockery of privacy laws and other good legislation if, e.g., irresponsible or tabloid media organizations can get around them by simply relocating content overseas.

    The argument could be raised, but thankfully the GPL contains an "as is" warning effectively from the author. The law of negligence says that if you warn people about the risks they are undertaking before they commit to something, the standard of care you owe is lowered. If I warn a person to whom I give my work about the potential dangers of that work, responsibility would be transferred from my shoulders to theirs. In addition, if I go so far as to give them the means to guard against any flaws in my work (by providing source in the case of software), then I probably have an effective defence in the form of contributory negligence if it blows up in their face. Finally, any case in negligence would be weakened by the enornmous social (and arguably economic) benefit that flows from me giving away software.

In that sense, it's just like any other industrial chemical process. The process used for each gene is apparently novel enough to ensure patentability (the test for novelty in the US is really low, along the lines of "if trained monkeys couldn't think it up, then it's novel"; the EU is better in this regard, but then again the EU is better in most respects with regard to IP, especially in relation to biotech and IT).

    What if I wanted to represent the same gene using different notation, using a different investigative process to get that representation?

As for using a different process to get the gene: that's a big argument. It's a bit like saying that you could produce say, a phonograph that corresponded in every way to a patented phonograph, but avoid the patent by saying you used a different production process. It doesn't really work that way.
