  1. Re:Trust a doctor on Do Sleepy Surgeons Have a Right To Operate? · · Score: 1

    I think the point is that doctors are being pressured by management into working excessive hours that negatively impact patient care.

    By making the patient aware of their tiredness, they are living up to their ethical responsibilities. By making the patient responsible for the choice, they are avoiding the pressure that would otherwise be deployed by their management, because they cannot operate on the patient without informed consent. If management pressures them to stop informing patients of their exhaustion level, that manager can be rightfully censured for reducing the quality of patient care.

    So this a dual win - conditions for the medics improve, and so does patient care.

    Please don't diss NHS doctors. Having been in exactly that position, a junior doctor too tired to do a proper job, I can tell you that the major reason the NHS is in such a world of pain originates from the top down, not the rank and file.

    The NHS has for some time been dependent on the goodwill and vocational motivation of it's healthcare professionals, because they sure as hell ain't motivated by the working conditions, pay, and benefits.

    The real problems in the NHS stem from multiple sources, including the increasing cost of healthcare consumables (increasingly expensive technology and pharmaceuticals), the costs of revolting profiteering (aka the "Private Finance Initiative"), targets set by politicians, an excess of managers, a decrease of basic common sense and an increase of feelings of entitlement amongst the UK population (I've seen people turn up in A&E (ER) depts for things as basic as a cold or a knee graze).

    Yet despite all this, we still achieve better health outcomes than the USA despite spending a quarter per-capita what they do on healthcare. Does this mean we are more than four times as competent?

    The story itself is from the New England Journal of Medicine - so has originated from doctors themselves, trying to improve the care that patients receive by fighting against the market forces that increasingly try to reduce medical professionals to the same depth as any other druge worker stuck in a poverty trap.

    We have a large private network and a 30 Mbit/s symmetric pipe as the internet gateway for the ENTIRE organization. I'm not talking a small company here, I'm talking the 3rd largest employer in Europe (after the Peoples Republican Army of China and the Indian railway).

    Even just 100 listeners to 32Kbit/s AAC streams would eat 10% of our incoming bandwidth.

    Realistically, I think YouTube probably eats most of our pipe, because our management decided that it had to be unblocked because we'd posted some video there. Although we suspect they did that to have a justification for unblocking it. Our upload speeds are great ; I've seen mid-day downloads as low as a few hundred bytes a second, which is really, really annoying when your work depends on server resources on the internet (because it's an external project), and you know that the download speeds are rather impressive before 0900 and after 1700 and are worst at lunchtime when everyone is getting their 'Tube fix.

  5. Encrypting passwords is less secure on Mozilla Posts File Containing Registered User Data · · Score: 3, Insightful

    Urrgh.

    Please, don't encrypt passwords. Encryption implies that you can retrieve them if you have the keys, which could have made this much worse.

    MD5 hashing is probably still a secure practice, done right, for a given degree of "secure". Like any kind of data security, it's all about raising the cost of obtaining the data beyond the amount that a given person is will to pay to do so. While MD5 costs less to crack these days, the cost to obtain each Mozilla user account password is probably still higher than most are willing to pay (although stealing the resources to do this via a botnet probably reduces this cost considerably).

    Given equally sound methodology, encrypting passwords is always less secure than hashing them, because encryption implies that you can retrieve the plaintext, which leaves it open to all sorts of additional attacks, like stealing the encryption keys along with the data, "persuading" the sysadmin to decrypt them with either a rubber hose or a wad of cash, etc, etc.

    On the other hand, hashing means that you genuinely cannot retrieve the password without expending a large amount of CPU time, and persuasion isn't going to help.

    Any site that will emails you your password as plaintext is doing it wrong - there is no reason that any authentication system should be able to retrieve your plaintext password. It's acceptable to offer a means to force a password change, it is NOT acceptable to send my password to me via a medium that any intervening server could read, and it's not acceptable to be storing passwords as plaintext or even encrypted when it is demonstrably less secure than hashing and there is no benefit to retaining them.

    In fact, you should mail the sysadmin of any such system and let him know that his system is doing it wrong, and why.

  6. Re:Oh boy, what's that cost per crime down to? on London Police Credit CCTV Cameras With Six Solved Crimes Per Day · · Score: 1

    PFI == the Private Finance Initiative

    Essentially, the cameras are built by a private company, with private money, and run by the private company, for the state. The private company has used it's dodgy lobbyists to get a sweetheart contract for some inordinately ludicrous fee.

    The contracts involved typically have basically zero risk in them for the corporation involved. The fees are guaranteed to increase each year above the rate of inflation, the duration of the contract (and they are long as 35 years) is guaranteed even if the service or infrastructure is no longer required (as in the case of a school with no pupils that the public will be paying a service contract on for the next 20 years) and the base costs that the fees are calculated on are fixed even if they are blatantly guaranteed to decrease over time (as they are in the case of surveillance equipment which like everything else electronic is cheaper every year).

    Typical healthcare PFI schemes have been calculated to cost the UK National Health Service around 3 times as much as the actual value of the project. Because private companies are now effectively in control of public spending, they ignore small potatoes like refurbishing two well-placed hospitals for £30M and instead opt to demolish them and build a poorly placed new one for £410M. The rate of return over 12 PFI hospital contracts was 58%, a level of private profit which is inappropriate for a public service.

    If the CCTV project is indeed a PFI project, you would expect the same corruption, waste, and profiteering to be involved there too.

    The experience with email and PGP just proves that most people are boneheads. The only places I see PGP (well, GPG) signatures are on software development mailing lists.

    "email" is the wrong metaphor. It misleads people into believing their messages are secure, because they are used to their mail being enclosed in an envelope - just like the one that basically every email program with a GUI depicts somewhere. It's more like a postcard. One that gets delivered via a network of disreputable postmen, some in the employ of enormous and sinister organizations, some just out for themselves. Encryption is the envelope, but people are happy to just keep sending postcards.

    I have the right tools installed, but honestly? The only time I even *sign* messages is to get a little kudos on those developers mailing lists. I don't bother encrypting mail because in general for the vast majority of recipients you're going to have to

    • Explain to them why email is insecure (it can be hard to persuade them of this)
    • Find PGP compliant tools that integrate with their chosen email solution (since most people use webmail, this is going to be hard)
    • Talk them through installing the tools
    • Talk them through key generation
    • Talk them through key management, distribution, and trust
    • Explain to them that yes, if they forget their password, they are *never* getting those mails back
    • No, I can't decrypt them, even though I encrypted them, because they are 'crypted with YOUR key
    • Explain public-key crypto

    If your chosen correspondent doesn't give up at some stage of this process, then you are either very persuasive or you have something important to hide. Or they are technical. It's an excellent measure of how much people value their privacy - most do not value it enough to have to expend significant mental effort to protect it. It remains to be seen how much this perception will be effected by the ongoing corporate harvesting of what would, in a "real world" social network, be considered private material.

    Now CollabNet are very big on Subversion, and selling services related to Subversion. So why oh why are they providing a server OS which installs a truly ancient version of one of their flagship products - 1.4.2 ? Lucid is on 1.6.6, Maverick is on 1.6.12 ; 1.4 is from 2006 ; there have been 2 LTS releases of Ubuntu Server since then.

    Yes, I know there is RPMForge. But the whole thing seems very amateur.

    Now, as for Gentoo vs Ubuntu ...

    I have respect for the Gentoo way of doing things. Gentoo was the only way I could get my MythTV box running when I first set it up, because it was the only distro I could find with support for the bleeding-edge drivers my TV capture hardware needed. Just installing Gentoo taught me more about the innards of Linux than anything else had done at the time and I wouldn't hesitate to recommend it to someone who a) had a lot of time on their hands and b) needed to know a lot about the innards of Linux with little previous experience. I do agree that it tends to attract the kind of user who is knowledgeable. The wiki in particular provided excellent documentation - that said, a lot of it deals with problems you only get with Gentoo because of the way it is ;-)

    Temper the comments above with consideration for the fact that I'm not up to date with Gentoo - I quit using it actively long before I cleaned it off my MythTV server and replaced it with Mythbuntu. There are still patches in the kernel to IR remote driver tables I wrote when using Gentoo, so it still has a place in my heart, but I really don't want to go back to watching compiler scrollback for hours on end.

    You don't need to use Portage to apply your own patches. In Ubuntu, you'd use a Personal Package Archive (PPA) - check out the sources for your package using the Canonical-sponsored Bazaar version control system, patch them, push the result up to the server, and the Canonical build farm will build a shiny new set of packages for you. Add your PPA to your apt sources list and your machine will update from them. You can keep your patched packages up to date with the official ones by merging the new revisions from the Bazaar branch.

    So overall, I use Ubuntu because it's more up to date than CentOS, because I understand it better (being my primary desktop OS and the basis of my MythTV server), and because it's friendlier than Gentoo. It has a larger user base - the squeakiest wheels get the most grease, so I think it's more likely that problems get found, making it more likely they get fixed. And I just can't justify waiting for my packages to compile ; I never got the hang of all the workarounds Gentoo has for this like farming builds out to other machines in your network.

    I'll raise a glass to Gentoo and all the rest of the diversity in the GNU/Linux OS space. They all bring their own dishes to the table and we are all better off for it.
