sadly, I am... I work for an ISP that generally doesn't make these mistakes, our network engineering/operations/construction team enjoys observing all the stupid things Centurylink and …

It very much depends on where the local speedtest.net server is in relation to you in terms of network topology. If you're in a large city like SF or Seattle, your ISP might host a 1U box from oo…

Usually because a customer can't properly articulate on the phone what's wrong with their connection. Last mile broadband providers want to do as much as possible to avoid a site visit to a …

It's a stupid idea to do a truck roll to resolve upstream peering/transit/congestion issues with the IP network. The technician's job is to diagnose OSI layer 1/2 issues to yo…

There's opennms + opentsdb + grafana solutions.

You did an SF-86 and went through the whole OPM background check process for Secret and weren't drug tested? Seriously?

pretty much the gold standard in extremely long life batteries, non rechargable lithium, but they're not cheap: http://www.tadiran.com/ …

From an ISP network engineering perspective, something like 85-90% of these tools are obsolete, no longer maintained, or proprietary to some particular manufacturer's platform. There's a muc…

The prefab functional/ugly architecture is remarkably similar to parts of the Bagram and Kandahar air bases, but obviously adapted for the polar climate. It makes sense when you consider that the…

24,000 twitter followers for $30, one time payment? Makes me wonder what the ratio of live humans to automatically generated bot-accounts on twitter is. And the total number of registered twitter use…

One of the major things not really addressed in the article is backhaul for each 4.5G/5G cell site or small cell site. More air spectrum and better radio modulation/MIMO for the cell-to-hand…

Time series does not necessarily have to be about 'huge' data either, just a much greater level of historical precision. Example: ISP sells a circuit with 95th percentile billing to a custom…

When you work for an intelligence agency, federal law enforcement, customs/immigration or something like that (or a private sector contractor for them), and the topic of discussion is the MILF? t…

you know the flash animation video that goes "badger badger badger badger badger"? https://www.youtube.com/watch?v=EIyixC9NsLI well, think like that, except; lawyer lawyer l…

We've been to the moon but humans have never put a manned craft in geostationary orbit, or returned from it - the delta-V requirements are different.

I'm saying sort of the opposite - there have been very, very rare cases where satellites in LEO were visited by humans and repaired or retrieved, but it's extremely uneconomical (Hubble, LDE…

Probably wouldn't have happened during launch, though, as the mechanism attaching it to the rotational base would've been replaced with a special pyro platform rigged with explosive bolts to…

Something as simple as software to prevent extended firings of a thruster for any reason would have worked. In a LEO satellite it's constantly being exposed to night/day cycles and isn'…

"We've put our automated checklist for site deployment on the internal mediawiki page at https://site.goes.here , problem is that Bob was trying to rack the 85 pound, 4U server c…

I know this was a science and LEO (low earth orbit) satellite, but here's something to consider when thinking about the difficulties of engineering hardware & software to work together in a s…

There are satellite that use the STT system almost entirely independently of all other systems. Particularly ones that need to remain in a certain orientation for 100% of their service life, such as g…

and definitely not an SNMP MIB

NSA will simply pwn the endpoint devices of whoever they're really interested in.

The major challenge now is no longer PV and gridtie inverters, but energy storage. Whether it's batteries, pumped storage hydroelectric, whatever. $$$ per kWh stored (and the lifetime/cycle …

Even if you can only write at 80MB/s it doesn't take that long to do 4TB.
