Mauro, SHUT THE FUCK UP!

It's a bug alright - in the kernel. How long have you been a
maintainer? And you *still* haven't learnt the first rule of kernel
maintenance?

If a change results in user programs breaking, it's a bug in the
kernel. We never EVER blame the user programs. How hard can this be to
understand?

To make matters worse, commit f0ed2ce840b3 is clearly total and utter
CRAP even if it didn't break applications. ENOENT is not a valid error
return from an ioctl. Never has been, never will be. ENOENT means "No
such file and directory", and is for path operations. ioctl's are done
on files that have already been opened, there's no way in hell that
ENOENT would ever be valid.

Shut up, Mauro. And I don't _ever_ want to hear that kind of obvious
garbage and idiocy from a kernel maintainer again. Seriously.

I'd wait for Rafael's patch to go through you, but I have another
error report in my mailbox of all KDE media applications being broken
by v3.8-rc1, and I bet it's the same kernel bug. And you've shown
yourself to not be competent in this issue, so I'll apply it directly
and immediately myself.

WE DO NOT BREAK USERSPACE!

Seriously. How hard is this rule to understand? We particularly don't
break user space with TOTAL CRAP. I'm angry, because your whole email
was so _horribly_ wrong, and the patch that broke things was so
obviously crap. The whole patch is incredibly broken shit. It adds an
insane error code (ENOENT), and then because it's so insane, it adds a
few places to fix it up ("ret == -ENOENT ? -EINVAL : ret").

The fact that you then try to make *excuses* for breaking user space,
and blaming some external program that *used* to work, is just
shameful. It's not how we work.

Fix your f*cking "compliance tool", because it is obviously broken.
And fix your approach to kernel programming.

Guess what is missing

The cost of latency

A very good explanation of why RAM > DISK > NETWORK:

 

• Registers & CPU cache (1 nanosecond): These are small, expensive and very fast memory slots. Memory controllers try mightily to keep this space populated with the data the CPU needs. A cache miss means a 100X speed penalty. Even with a 95% hit rate, CPU cache misses waste half the time.

 

• Main memory (10^2 nanoseconds): If your computer was an office, RAM would be the desk scattered with manuals and scraps of paper. The kernel is there, reserving Papal land-grant-sized chunks of memory for its own mysterious purposes. So are the programs that are either running or waiting to run, network packets you are receiving, data the kernel thinks it's going to need, and (if you want your program to run fast) your working set. RAM is hundreds of times slower than a register but still orders of magnitude faster than anything else. That's why server people go to such lengths to jam more and more RAM in.

 

• Solid-state drive (10^5 nanoseconds): SSDs can greatly improve the performance of systems with working sets too large to fit into main memory. Being "only" one thousand times slower than RAM, solid-state devices can be used as ersatz memory. It will take a few more years for SSDs to replace  magnetic disks. And then we'll have to rewrite software tuned for the RAM / magnetic gap and not for the new reality.

 

• Magnetic disk (10^7 nanoseconds): Magnetic storage can handle large, contiguous streams of data very well. Random disk access is what kills performance. The latency gap between RAM and magnetic disks is so great that it's hard to overstate its importance. It's like the difference between having a dollar in your wallet and having your mom send you a dollar in the mail. The other important fact is that access time varies wildly. You can get at any part of RAM or SSD in about the same time, but a hard disk has a physical metal arm that swings around to reach the right part of the magnetic platter.

 

• Network (10^6 to 10^9 nanoseconds): Other computers. Unless you control that computer too, and it's less than a hundred feet away, network calls should be a last resort.

The Cloud's Silver Lining

In the platform space, Cloud Foundry seems to be leading that charge. They've even recently released a Cloud Foundry Core which enables them to provide users with some level of assurance between the different Cloud Foundry providers.... the approach of VMware towards creating a marketplace is enlightened in my view. They've got a good shot at making a large competitive market happen.

HP Unveils Cloud Application Platform Powered by ActiveState which in turn is powered by CLOUD FOUNDRY

The battle for the cloud continues to heat up with HP announcing earlier today the latest addition to its portfolio of cloud related products and services.  Called the HP Cloud Application PaaS, the offer fills a hole in its cloud portfolio in an area commonly referred to as Platform as a Service or PaaS. (blah blah blah) settling on Vancouver, British Columbia based ActiveState and its Stackato PaaS software. The HP Cloud Application PaaS will be a fundamental component of the HP Cloud (blah blah blah) and with this announcement HP’s Cloud grabs a potentially big technological advantage. Expect other cloud providers to do the same by quickly following HP’s lead of an integrated PaaS technology as key a differentiator. It’s also interesting to see that HP has selected ActiveState to form the core of its new PaaS offering. ActiveState’s Stackato is built atop VMware’s Cloudfoundry project, and is described as an application platform for creating your own private, secure, and flexible enterprise Platform-as-a-Service (PaaS) using any language on any stack on any cloud.
