The last time I got a tour of the SIX, there were switches on two different floors in the Westin building. This is more for capacity than redundancy. The original location is literally a janitor's closet in a hallway and it's so

The intent of the standard /48 end user size was to prevent residential ISP's from being stingy and only assigning one IP. They wanted homes to have as many publicly routable subnets as the would ever need or want. This was later

The IETF IPv6 allocation scheme was crazy from the start. The standard subnet size for autoconfiguration purposes is /64 = 18 Billion Trillion addresses. Of course reality is that autoconfiguration is only marginally useful and lots o

Excessively large buffers confuses TCP windowing. On network devices like switches and routers buffers are only actually needed for two things: internal switching/routing latency (which is usually constant and very small) and serializa

All it takes is two or three manufacturers to agree on an interoperable standard and consumers will force the rest on board.

NTSC has a number of artifacts but this simulation added RF decoding artifacts as well. The RF artifacts completely overwhelm the NTSC artifacts. It looks like a fairly weak RF signal plus other RF noise/harmonics in band.

There is a known hardware bug affecting every PSU and cards in the 6500/7600 series. It manifests as a significant chance of permanent failure on power-up after being on for several years. As long as the chassis stays powered everyth

I didn't realize Atari made a 68030 machine. It's too bad they didn't pivot to high end engineering/academic workstations to compete with Sun/SGI. They definitely had the engineering talent.

This is one problem (of many) that will have to be solved before we can have "generation ships" for interstellar travel.

Just about every electronic circuit I designed and built as a teenager used one or more 555's. The most practical was a repeater controller for ham radio. The most interesting was probably a pulse width modulator a/d converter. Th

Interesting... this implies 64 bits per pixel. What format would that be, 16 bits per color RGBA?

Is the viewer open source? I saw links to give credit to various open source libraries/utils but I didn't see a link to the actual system. It works really well. I'd love to use this for one of my projects.

I wish this were being turned into a museum ship like the USS Midway. It's unique since it's the only surviving member of it's class. I guess it wasn't notable enough. Hopefully the Nimitz will become a museum when it i

Titles are cheap. Better questions: Do you have the knowledge and experience to do your job well? Is your brain naturally wired for the type of work you do?

I wrote my first web app in 2000 using C/mysql. It was Insanely fast but very awkward to implement. I used C because it was (and still is) the only language I knew well. At least if you are going to use C, you (should) know to be ext

The last time I looked at c++ (mid-1990's) it generated hugely bloated binaries and was generally slower at runtime than plain C. Is that still true today? Is there any language (other than assembly) that is faster at runtime than C

It does seem like an overreaction to me but there is a big difference in cell towers and satellite uplinks/downlinks Radio towers (sites) have widely varying quality control of their tenant's installations. Other transmitters can

The general concept is correct but there are a few issues with the article: - Specific RGB values always depend on a selected white balance temperature. If the WB temp is the same as the object's temp it would be white, not blue. If

This is one reason why I am a big proponent of network engineers physically visiting their equipment periodically. In large networks that may never happen, data center techs (often not even your own employees) are the only ones who ever s

There are two main uses for this kind of thing. - Legit: debugging/monitoring. Other legit uses are theoretically possible but the device has severe limitations that likely make them impractical or unwise. - Surreptitious: This is cl
