You are absolutely correct, but apart from textbooks most of the rest do apply at times and thus it qualifies for "news for nerds" IMO. I passed out from my engineering college last summer and thus i understand perfectly well what the summary says.I do not know if i am bright or not.But i know that I was better than perhaps most of the students in my class.Yet at the same time i got grades in the lower ranges.Honestly i found out things which I *think* responsible for it -
- There were no examples in terms of professors/student to whom we can look upon.
- I did not like the notion of theory without any practical demonstration(sadly I feel so even in Computer Science).
- Lack of freedom of choice as per language, tool, development environment etc etc.
- Some of the textbooks were really really badly written.
- Exam laid emphasis on slogging rather than conceptual clarity. e.g state 5 differences between X and Y.I mean, what if I can think of just 2 or 3?Am i supposed to mug exactly 5 differences.
- Lecturers considered my previous grades before giving me grades for a practical exam.(This is seriously retarded thing)
- Lecturers forced us to listen to their lectures, no matter how uninteresting were they.
- Other students were mostly more interested in impressing lecturers to get good grades in practical classes/exams, which in turn means asking really really stupid questions despite knowing answers.some will even go on to ask things like - "Does a router have something like a processor?".And which i avoided thus damaging my practical grades severely.
I may be a product of disillusioned student life which i have left for now, but I know atleast that I am better than what my grades show.Perhaps thats the reason i work as a kernel hacker full time these days.

You can't teach ability to choose a different solution.

Well i completely agree but from someone who is an Indian citizen and thus an Indian student, i ll try to present the unknown half of the story.you may call it what you feel like, but your story reminds me of my school days and after math of education system in India.
During my primary standard school i use to finish my whole syllabus before the start of the new term.I am not a genius neither did i take an IQ test, nor do i think i have an IQ of 145+ but i like studying books in my free time.Science was the most easiest and trivial subject to me.As a sidenote for many/.ers, India has an education system which forces you to put more emphasis on marks and not understanding. This leads to mugging and poor understanding of the subject.I ll admit mugging when i was a kid, cuz this is how we all are brought up.Though i had to mug for grades, i never liked it.
After school i went to college for my bachelors in Computers.I realised within one week that i cannot mug anymore somehow. I felt attending classes was a waste of my time. Attending practicals which force you to work rather than learn was a torture. As expected i failed miserably at my grade in my first year of college. That was shock to me.But soon i realised grades do not matter, what matters more is my own satisfaction. Why should i follow the path which makes me feel knowledgeless. Honestly i chose to stop following the stupid rules in college, got one of the lowest marks in the class but managed to get through. I remember being touted as one of the idiot students who do not know a thing about their major.duh... it hurts when those words are from your faculty.Reason being i never liked the idea of sitting at back bench and asking questions which don't make sense. I would prefer reading books and breaking my computer, and personally i learnt more this way.luckily i managed to pass somehow.
Twist of fate, as it seems.My first job after college turned out to be a R&D job where i work as a virtualization hacker full time along with some stints on High Performance computing. And this all makes sense to me.I always liked challenges, and this job is a challenge.I don't regret not following the herd but what i do regret is low grades i got. I know now it may not matter but somehow it hurts.
I hope in US you people get good enough grades for following your heart at colleges?
Seriously, better late than never. No software is perfect,no package is absolutely secure. Its good that these servers were compromised and detected too[i hope withing time]. This means either admins are not doing their job properly or the culprit packages are buggy. Either way it is an eye opener to the community and especially Canonical. This calls for better auditing and more effort to be put into security on Ubuntu server systems as well as packages which make their way into Ubuntu. This may possibly mean more work for Ubuntu package maintainers and in turn a better product[not the perfect one but a better one].
We do need LUGs !!! LUG is not only about solving or troubleshooting other user's Linux problems, but also about knowing and meeting with people who share the same mindset(mostly). Email is good but effectively in person conversation prevails over emails.
Definitely its not the end of LUGs, but we need more awareness among people and students alike about LUGs. The FOSS/Linux bug has just started in a true sense, therefore this calls fore enthusiastic people to common under single roof.
May be you have a jovial nature, good for you but not good when it comes to usage. different package management techniques, different places where you will find standard files/binaries, different way you compile your software(e.g kernel src), different way you write some of the scripts.
I personally used rpm based RedHat, Fedora, for long. Then came to Ubuntu. Certain things were not in the places they were in Fedora. Figured it out eventually. Then switched to Gentoo and again a shocker, different places where you have edit some random scripts to make it work smoothly.
Had there been a uniformity it would have been almost a zero effort process to switch among them. Since now i have used i have no problems with any of them.
This is exactly what makes Linux distro switching messy , sometimes despite i am Linux developer.
e.g I tried installing runit on Ubuntu but the installation failed, because now they don't use init, they use upstart and which means i do not have an/etc/inittab. How is that? Easy for me to fix,not so easy for an end user who switched to Linux.
The problem which author perhaps missed can summed up as -
- lack of coherency of packages/package management and tools among distros.
- lack of a common template or rules or standards over which distros can be made.
But at the same time it does happen doesn't it? e.g for car there are a thousand varities out there. Anyway To protect this LSB(linux standards base) is formed.
BTW linux kernel is still same and shared by all.Only versions used are different.
So its just the userspace tools and programs which vary. And thats not bad as different people have different taste.
Yes it is.But question was if i understood it correctly, built in support for virtualization.And KVM does help a hypervisor if it is going to use hardware virtualization like AMD's SVM or Intel's VT-x technique.
May be i am misunderstanding something? but i would like to be corrected verbatim.
Really my wrist hurts as using mouse is obligation on my desktop, and that too for an average of 12 hours a day.
I know, i know CLI is there but CLI browsers are no match for GUI browsers sadly.
Moreover i would love to use keyboard keys for everything and for those who feel like me shifting to a more keyboard centric environment, try fluxbox. Wicked cool with all things in place, plus it is fast too, not to mention custom ways you can mould it to.
> * The ability to scale from supercomputers, mainframes to handhelds, without recompilation
Thats next to impossible for a modern fairly efficient operating system. Why? Because kernels which run on handhelds , supercomputers and mainframes have different constraints in terms of memory, power management and similar technical terminological stuff:).
> * Transparent clustering. Run this process somewhere else with as much or as little user control is a required
Oh boy!!! this is how SMP kernels work when you run them on a multiprocessor systems.
> * Fine grained security. Maybe something which lets you build a userland which can't be exploited in any way shape or form
lolz...:D i would mod you funny, but thats idiotic, why should kernel worry about user code at all? BTW if you are so paranoid try SELinux.
> * Built in support for virtual machines. Something like java in the kernel
This is what VMI (Virtual machine Interface) does right now in the kernel along with the KVM(kernel virtual machine) and please do not compare and OS with Java stuff. Java do not deserve to be compared to a highly performing kernel.
> * Better APIs for kernel modules. Being able to run some modules in a real sandbox
BTW whats wrong with current APIs?I do not find anything wrong being a developer.And i bet no user needs API, because they do not even care which kernel it is forget API. Sandbox yes, try Xen or any other virtual machine.But do not try to expect a fault tolerant monolithic kernel just for the sake of weird fantasy[atleast not so soon:)]
Current firewire stack is way too small in size as compared to old firewire stack.
Second now there are less threads in the firewire subsystem, which is indeed good because kernel threads are really really a very stupid idea.
Last but not the least i have used TI firewire chipset with Basler IEE1394 cameras under Linux and trust me they knock teeth out of Windows Firewire stack.It was good and performed good even with two cameras working in real time image inspections.
I suspect the current stack is going to work atleast similar if not better, though i ll bet on it being better.This is a good sign also, as there is no point in patching things but point is in writing the whole messy thing again.And here we are.... hey wait TTY layer...any takers? please:-)
BTW in short plain english, it adds some voodoo stuff to struct page, removes a lot of metadata cruft from the slab allocator, adds lesser and simple locking after removing most of locks which are not required because of the changes in the cache layer.
So if you are running your kernel on a huge farm of processors of the order of thousand(s), you ll find a remarkable memory saving, which is a big overhead in slab allocation.
I wonder where were you all these years?Qt needs people who can spread the word.It is indeed beautiful. And what i mean by beautiful is something to do with the way it is designed rather that what it does, although the outcome is indeed soothing to eyes without any mess.
Simple, clean and efficient. Moreover the elegant code which makes use of the OOD so well, does makes one more thing great and that is overiding the builtin capabilites. Yes you heard it right, you can change it because you did not like the way Qt works for your X component feature.And that too without breaking anything *mostly*:-).
A perfect example how to write object oriented code.
