There is almost no applications that require memory from that 256MB. Each unit is pretty well independent. For example, the Mast Camera has 16GB of flash memory and can do hardware compression on the fly.
So yes, 256MB is plenty. It is almost like 256MB dedicated to the kernel.
Each camera has eight gigabytes of flash memory, which is capable of storing over 5,500 raw images, and can apply real time lossless data compression.[62] The cameras have an autofocus capability that allows them to focus on objects from 2.1 m (6 ft 11 in) to infinity.[65] In addition to the fixed RGBG Bayer pattern filter, each camera has an eight-position filter wheel. While the Bayer filter reduces visible light throughput, all three colors are mostly transparent at wavelengths longer than 700 nm, and have minimal effect on such infrared observations.[62]
Hey man, my questions were serious. Do you have time to review them for myself and the community? I don't mean for you to do any research, just answer them to the best of your knowledge if you can.
I enjoy taking advice from many sources but in the end, I should have replied "I do, but who says I necessarily apply that advice".
You seem to know much more than I do so I have questions for you:
1) What is the layer of this management protocol? I mean IP or ether? What if you have a fiber adapter?
2) I assumed it wasn't IP but some lower level protocol and that it couldn't be possibly reached in any case through the Internet. Am I right?
3) If I ever was right in question 2; how close do you need to be from the server to attack it? For example, I understand that anything using a hub wouldn't be an obstacle but would a switch properly configured prevent reaching the server?
4) My home and other servers have non-Intel adapter for that very reason but the data center server uses an Intel adapter. Am I correct to assume that I am not vulnerable if I don't use an Intel adapter?
If it helps, the server adapter is: Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02)
P.S. I have downloaded stuff from Intel before to test this but I am afraid to fall even deeper in the pit since it looks like you have to install a module! Not that I am afraid to build a kernel module or even flash firmware but trust in Intel at this point is as low as expected especially if you take into account the various problems that surfaced in handling the situation after this was made public.
How could I possibly really test this on the data center server without Intel tools? Renting a throw away machine on the same rack just for the purpose of the test?:)
More details: I don't even use the save password feature and I read my emails in pine. So, I will never ever need a recovery key for firefox. I have a proper backup strategy for everything including firefox configs and bookmarks. Backups are made on an encrypted partition on a remote data center on a server which I control fully and which nobody else can access since I wiped the disks and installed my own OS and I check for reboots and physical tampering with the intrusion sensor which tells you in the case is ever opened.
Also the remote backup server logs to a computer in my house in real time through a vpn to make sure I have a log copy what ever happens example from syslog.conf: authpriv.* -/var/log/secure authpriv.* @10.256.222.53// this is my home server
So the remote backup server logs locally on its disk and to my home server in real time.

Correct, it is crazy. A lot of companies try to duplicate a lot of stuff that already exists in one "web app" or just "app", sometimes using the silliest protocols instead of the existing ones.
I had a chat with a marketing person from our company and she said:
"We are in the modern era, people don't want to open a mail client, an IRC client, etc. We need to have a product that just does it all."
So nowadays, some marketing people find it unacceptable and too complicated to ask people to open and learn how to use clients like, mail, irc, etc. Often, they have a hard time using those clients themselves or worse, they don't even know such things as IRC exists.
It is a general tendency that I have observed lately, many people try to re-invent what already exists and they don't even know it already exists!
Us in the US would have switched a long time ago to align with France but England beat us to it and now we have to maintain our distinctive independence from the British monarchy hence we keep using different units.
Hahaha... I remember being on Microsoft campus just after they released Windows 2000 server and they had those 5 nines posters all over the campus. I took it with a grain of salt but they seemed really serious about this.
Common hot water or steam systems for the neighborhood seems like a good idea. I haven't seen in North America.
In Quebec City, they have that incinerator built decades ago to burn their household garbage, it is located right downtown and at least they thought from the beginning about generating steam for the Daishowa located right across the street. I guess that counts as a start.
Well, California, now Facebook, what will be the next article published on/. ? I suggest "Slashdot Aims To Power Itself With 100% Renewable Energy by 2020"...

That's why they have so called "military-grade" versions of the COTS. Now soon to be called "cyber-space-grade" I guess...
So in the end, they are not supposed to be COTS processors.

Na, you are confusing it with old tin cans that were lined. Aluminum cans aren't and that's one of the reasons that they are easily recyclable.
Not sure how much testing has been done with regards to the toxicity of aluminum although...

C could be a lot better at being closer to the machine. It actually lacks several features in order to placate defunct architectures. ....

To name a few. Anyone else know of a "saner C" standard that makes most of the undefined-ness go away?
you forgot to mention off by one errors; 'z'-'a'==25, not 26 as far as I know...
I hear they tried that robot in Montreal and it crashed due to memory exhaustion.
Montreal is one of the oldest city in North America and there are so many leaks in its water system that it loses 30% of its fresh water supply.
Makes you wonder what is the average water loss in other systems.
