And it is why I was using Mozilla 1.7 for past couple of months.

FireFox 0.9 crashes on complicated pages which has flash animations and too many pictures. It happens on two of my computers. (Yes, I double checked the setup. It happens with and without plug-ins installed).

Goodbye FireFox for now. I love Mozilla 1.7.2.

Filtering bogon routes is a good idea, but not after IANA allocated one of those so-far bogon routes to RIRs.

Filtering of unallocated address space (a.k.a. bogon filtering) is becoming more prolific. This is a good thing. However when those filters are not kept up-to-date they can quickly become too much of a good thing. Recently users of first allocations out of new blocks have experienced problems and aired them on lists like NANOG and in the press. Also, prominent resources like some root name servers were not reachable from a recently assigned address block because of out-of-date bogon packet filters.

Making bluetooth devices work with a PC is not always easy as it supposed to be.

If you are unlucky enough to have a Belkin, Giga-byte or any other hardware that use WIDCOMM driver, then its likely that your hardware comes with an incomplete driver that does not support many profiles and does not work with latest service pack of Windows XP. Downloading the latest driver from the manufacturer website won't help. Don't waste your time.

It's your right to have a complete driver when you pay for a hardware. So go ahead and download the latest driver from WIDCOMM website and read instructions from this website to patch your WIDCOMM driver and make it work with your hardware.

Thanks to that guide, now I can sync my SE K700i with Outlook, using excellent fma software. Connecting my bluetooth headset to my pc as a PC headset and make it work with my IP SoftPhone was another cool thing I did.

Bluetooth is a good technology, but with a "working" driver. Payam would agree.

If you are living in *BSD world and you are also doing network stuff for your personal use or at work, chances are high you know dummynet and use ipfw and dummynet for traffic management. Dummynet supports WF2Q+ queuing algorithm.

If you need to do more complex traffic management, ALTQ from Kenjiro Cho is your pal. Unlike Dummynet, ALTQ is not built into FreeBSD distribution by default and its a little bit tricky to make it work in FreeBSD. But if you are using OpenBSD, it will be a piece of cake for you because it is already imported into OpenBSD source tree and works fine with pf.

ALTQ supports WFQ, CBQ, RED, RIO, HSFC and some other queuing algorithms. For more information on different algorithms, I suggest having a look at Sally Floyd's homepage.
