  1. Re:so clam breaks if a remote server is down? on ClamAV Forced Upgrade Breaks Email Servers · · Score: 1

    If you don't intend to apply the security fixes to your server, do not run a server.
    Afaict a lot of debian users think (and the messages in the installer and the information on the website implies it) that if they have the security repositry in the sources.list and run apt-get update && apt-get upgrade (or the equivalent commands for their preferred high level package manager) frequently that they have done all they reasonably can do regarding keeping their server patched.

    However this is NOT enough. Sometimes the debian security team will consider a version of something unsupportable before security support for the release in general is discontinued. Users needing security support for said package need to make other arrangements (e.g. using volatile). However they will only know that they need to do so if they subscribe to the debian-security-announce mailing list. This fact is NOT well communicated to users (the debian page on "security information" makes no mention of this fact!).

    If you are running Debian on a server and are not subscribed to that list I suggest you both subscribe to it ASAP AND go through the list archives! If you run another distribution I suggest you check for a similar list there.

    Indeed clamav were stuck between a rock and a hard place on this one. Whichever option they chose some people would say it was the wrong one.

    The real problem is that there was no effective way of communicating this to users. People clearly either didn't read logs or took the "don't panic" part of the log message a bit to literally and didn't realise they should be subscribed to the announce list for the virus scanner.

    Desktop AV posts lots of nag messages to the screen when updates are going to be discontinued but that isn't really practical for an AV that is both running on a server and only a small part of the larger soloution (in the unix traditions of ways of doing things).

    Further compounding the problem is that Debian put clamav in stable and then abandoned the version in stable telling users to use the one from volatile (because ClamAV had made changes that weren't acceptable within a stable release) but not everyone knows about volatile (it's a relatively recent addition). Most likely in future releases Debian will only put clamav in volatile.

    It doesn't have to be so extreme though. You can always implement pieces of the game not related to rendering on the server. Which is essentially why Ubisoft has done here.

    It is the same with Paypal and credit cards with the difference that the merchant pays the markup.
    The thing with services like this is you end up paying TWICE. You end up paying card/paypal fees shipping etc to the original vendor, and then you end up paying them again to the forwarder plus the forwarder needs to cover thier time and efford making and forwarding the order and make some profit.

    Sometimes you end up paying sales tax in the forwarder's jurisdiction too (at least that was the case when I looked into using a service called "shop any american store" to get an item from the US sent to the UK).

    The net result is that this is an expensive way to buy stuff. If I can find a vendor who will ship direct it will almost certainly be much cheaper.

  5. Re:why even have an ip.v whatever on What Happens When IPv4 Address Space Is Gone · · Score: 1

    good question and there are a few reasons all coming back to the internet's nature as a packet switched network

    Firstly there is the fact that matching on variable length and potentially text strings is a lot more overhead than matching parts of numbers that have a known maximum length (so you can have fixed size address and mask fields for your routes)

    Secondly there is aggregation. Domain names are allocated to machines administered by the same company but which may (should) be spread over the internet. IP blocks are allocated to providers and larger companies and machines on the same network tend to use bits of the same block. This makes the routing tables FAR simpler than if every machine was routed individually.

    Thirdly there is packet size overhead, each packet needs the addresses of two machines, the sender and the recipiant. While IPV6 addresses are much longer than V4 ones they are still much shorter than an average full text address (particulally a client address) would be.

    The real problem is that the grid is ancient (relatively) and uses old, broken tech.
    There isn't really anything wrong with the tech per-se.

    The real problem IMO is that electricity is expensive to store and storage capcity for it is very limited. While wholesale electricity is a complex market designed to take account of this retail electricity is still sold on a very crude system (at worst the same rate at all times, at best a couple of rates based on time of day).

    There is talk of pushing retail customers towards time of day pricing but I would expect a lot of resistance to it because it will add a lot of worry about electricity costs that those customers don't really want to deal with. It will also require a complete replacement of metering equipment.

    Don't you think the power company already knows how much power you're using?

    With "smart meters" they know exactly what each individual customer is using when.

    Netbooks with 2 and 4GB flash disks prove this.
    Notice that those (and the slightly later models with about 20GB of flash and a screen that actually filled the space available) have mostly dissapeared replaced by slightly larger ones with 80GB-160GB HDDs? Performance (particulally write performance) on those things was shit and the capacity limit was pretty crippling.

    One thing to remember is that individual flash chips aren't particulally fast but by combining lots of them in paralell with a good controller high performance can be acheived. OTOH devices like USB sticks with a cheap controller and a handfull of flash chips tend to be slower than HDDs (especially when writing). This along with mounting requirements means that the price floor for SSDs that actually perform better than hard drives and can be fitted in place of a traditional hard drive will be higher than USB sticks, CF cards etc.

    Not saying this incident is excusable (they REALLY should be testing every version of core windows files, surely it can't be that hard to extract every MS patch to a "test clean" directory) but they can't be expected to check every bit of software out there.

    Afaict the reason desktop CPUs aren't soldered to the motherboard (many laptop CPUs are because thickness is at a premium) is because it would mean OEMs would have to decide what CPU was going in a machine much earlier. This would both require the OEM to hold more stock (bad for the OEM) and make the OEM less likely to offer higher end CPUs as build to order options (bad for intel).

    With socketed CPUs an OEM can design and build most of a system and only decide late on in the process (sometimes even only when the customer actually buys it) what CPU to drop in and hence where in the lineup it will come.

Especially as even with the integrated graphics disabled these will probablly be among the most power efficiant chips in their class.
