Concordia wasn't a huge problem because it drifted onto solid ground shallow enough to keep it mostly above water. If it had not been carried by onshore winds, it would have been a much different story. The captain waited far to long to declare it time to abandon.
Wifi only works because it is extremely short range, and even then it sucks in sufficiently crowded areas. Trying to do cell service that way would be a disaster.
And those people would be stupid. It's the exact same reason you don't have 12 competing power line systems coming through your neighborhood.
If you want to see what that *did* look like, there is clear historical documentation as such, and furthermore, it is what caused those "governmnet granted barriers to entry" in the first place.
And yet they clearly should have looked at least *a little bit* into the PR firm they hired. Even a cursory glance at their website shows massive copyright infringement and fraudulent credentials.
But that's the point, the buffers smooth the link, but not the streams going across them. At enough of a buffer bloat, the buffers actually make the link have to retransmit the same data multiple times due to the design of TCP congestion avoidance.
No, buffers are not for "rare peaks". They are fundamentally required due to the physics of data transmission from one device to another, especially when the link speeds are different from one hop to the next.
The problem with buffers is most all of the time they are configured by size in bits. They need to be sized based on bit flight time of the circuit, which is in delay ms times throughput in bits. The disconnect between those values is a problem in *either* direction, especially past the retransmit threshold on the above side.
Buffers should be dynamicly sized based on flight time of data on the specifc link, and ideally kept updated. WRED is also highly suggested.
What really exacerbates the issue is devices with buffers that must be the same size for all links on X (be it card, slot, or chassis).
That is actually the exact problem. You do not want buffers larger than the flight time of your circuit. You absolutely want the buffers to fill and drop packets otherwise.
Judging by the rest of the article, I strongly suspect it has more to do with enabling their secure hierarchy of kerebos based logins than turning off the exploit they used. You can see some of the other things they do relate to features that require a 5+ openSSH once they're in.
Do you know why satellites last so long in a hostile environment?... because nobody touches them.
"If it's not broken, don't fix it."
Actually I'm pretty sure it's the millions that are spent engineering each individual one so that it specifically can survive many years in said hostile enviroment.
If we spent anywhere near what is spent on proper engineering in time and money, everyday crap would be pretty damn reliable too, just not nearly as cost effective
That is quite possibly the stupidest thing I have ever heard. Government is not 1 grand magical unified entity. Every hiring group has their own policies and goals, and they are not interested in what is best for the workers, but what is best for themselves. This fantasy that government is a single anthropomorphic creature is a complete lie and should be obvious to anyone with a clue.
Look, after years of going around schlepping their drugs to doctors, the pharm companies realized that they were going about it all wrong. Instead, they took their message to the masses, and let self-diagnosing consumers tell the doctors what they wanted.
Now, IT providers are doing the same thing, and if IT service companies (which is all any IT department really is) want to keep their piece of the pie they'll do like the doctors did and get on board.
Have you noticed how med costs have changed the last few years? =)
If you don't mind becoming Somalia in the process. You can't just call your credit card company and tell them "Screw you, i have the money, but i refuse to pay for things i bought" and expect no consequences.
Umm, no, it is the regulation of the single tech spectrum that is exactly why other countries have better mobile infrastructure, not stupidly creating more islands of spectrum.

Hate to break it to you, but those aren't extreme cases. I've personally set up sites with 2 T1 backhaul that sold 6mb DSL.

Yeah just look at Wal-Mart. They're doing horrible.

More likely no one trusts them to be a member of a cartel and not stab them in the back.
But it's not "save my ass" its "keep me alive for a few more weeks-months, all the while I am in agony due to the chemo, etc."
Doctors don't ignore saving, they generally don't go for "slightly longer lifespan, much less enjoyment of the time left"
No, because these are public companies, and their executives would be personally liable for the damage to the stock by this kind of action.

No True Scottsman indeed!

Tell that to Africa
Being an SQL server that sometimes didn't even corrupt data isn't enough. How's MySQL scalability compared to Oracle, DB2, or Sybase?
A hell of a lot cheaper?

Do what now? How do you go from seeing underwear potentially accidentally to *rape*?!
There is something *seriously* wrong here, but I'm pretty sure it's with you, not the name of the software.
Umm, no, it is the regulation of the single tech spectrum that is exactly why other countries have better mobile infrastructure, not stupidly creating more islands of spectrum.
And then they wonder why they are getting class action lawsuits when all their data gets hacked and stolen.
So turn the law that Arizona made for the public to sue cops against the prosecutors that don't pursue.
