Video processing is not done through multi-processing with shared memory. It's done in batch, in a grid-type environment. Weather prediction almost certainly uses special-purpose math libraries (ScaLAPACK, etc.) in a MIMD environment.
Basically what we (the community) has figured out is that SSI featuresets should not be implemeneted in the OS layer, but below it. Look at the SGI Altix technology. Or large Unisys machines. Or that hyper-transport happy monstrosity that Cray is building. They have special low-level firmwares running on the I/O processors that are doing in low latency, tuned hardware what *Mosix was trying to do from Ring 0 on the nodes.
Using various ISA interfaces (MPI in the low end, or Hypervisor abstractions like Xen, etc. etc.) you can run many guest OSs in the space as needs require, and localize the shared-memory-ness as required to get maximum threading benefit with the lowest total latency you can tolerate. All this with minimally modified guest OSs in which to run the code. This is a much better situation then heavily modified kernels pretending to be a single system image (and then having to worry about forking/threading/VFS issues and propogation of that stuff).
On the flip side, grid technology and speciality message-passing libraries fill out the feature set for more embarassingly parallel problems that need lots of CPU and RAM... you have the luxury of spending time and money coding your applications for that environment if you are CPU limited.
Mosix doesn't have much use anymore as a general purpose product. Either it's too heavy-weight (and drowning in syncro overhead) and we should be relying on firmware/hypervisors that are customized for the hardware, or it's not necessary because we can handle the load balancing at a higher level.
Killed a lot of the cool infrastructure, although kept the change tracking/multiediting features and put then into 2007 for SharePoint integration. I'm not really sure why... at the very least they didn't keep the pluggable-presence protocol (useful for stuff other than Office) and offline change sync, which I think were killer features.
Probably NIH. Or maybe it was too powerful to include in the base products? I don't know.
Windows NT 5+ w/at least IE6.0 can browse WebDAV resources... they call them Web Folders or something like that. The interface is similar to browsing FTP resources (you can drag-n-drop, and when you doubleclick stuff it downloads to a temp directory and then runs the shell action selected in the menu)
And I'm pretty sure if you have XP or 2003 or Vista the standard file dialog supports it too.
I work in a technical environment with experienced individuals from other industries. Tech staff are still discovering frozen panes in Excel, page numbering in Word, change tracking, etc. for the first time.
Regardless of intelligence, when people learn how to use a tool in an adhoc manner (or even if they have training) they will fall into a habitual usage pattern, their comfort zone. They may not even be aware of features to solve problems they use inefficient methods for (page numbering, etc.) and will not even consider looking in the help documentation since they don't expect the feature, or don't know what it's called.
Tools like Office, Photoshop, and the like will always be like this. And switching the tool on people (even if it's functionally equivalent) takes the user out of the comfort zone and as their productivity suffers, they lament the change.
It would be helpful if those classes in HS/College that teach you "Business Skills" or "Typing" didn't just teach a software application, but actually taught you about the tools and approaches in general so that the end-user had a good feel for what tasks can be automated/assisted by commonly available software.
The drones (and bombs) are really expensive. They will still be really expensive for some time. As much money as the DoD spends, they are still stingy when it comes to such things. They put a lot of value on seniority and training before they put someone in control of expensive items. A munition that misses its target is a bad thing because it missed and it cost a few hundred grand, thus wasting the equivalent of a staff year of resources. That does not look good for the person who fat fingered it or his/her commanding officer. (The collateral damage is also undesirable, but the financial argument holds whether or not the people doing the bombing care about civilians)
You have to be an officer with training and seniority and everything before you get to play with these toys. The potential liabilities for the operator are just as severe as if they put you in a jet.
I mean, you don't give a couple hundred thousand dollars worth of munitions and secure radios to some flyboy just out of basic training. It doesn't matter what they're strapped to.
If you have a really good tech periodical with a userbase and forums, you should start charging for accounts. Paradoxically, people will want to pay you for the priviledge of being a "member" and not an anonymous hee-haw who can only comment on articles after entering a CAPTCHA.
And you can open up member-only services, like a coupon code board or something like that to entice people.
Use dm-crypt with LUKS in the aes-cbc-essiv:sha256 mode (should be the default). There are policy issues and known plaintext attacks against loop-AES unless you the multi-key setup which _isn't_ the default... by the times the issues were widely known people were using LUKS because key management is more flexible.
The issue has nothing to do with FOSS. It's because the BBC is supposed to making their broadcasts available to everyone (a side effect of being a government monopoly). As such, tying the DRM to a single platform is discriminatory. OSS has nothing to do with it.
Anybody can manufacture a device to pick up terrestrial broadcasts. But only Microsoft can make the software required to view internet broadcasts? That's an issue that deserves to be corrected.
I would never want a personal media device to take initiative to disable or delete data. What if I ripped that MP3 legally from a CD I own? Would I have to pre-protect it with their propietary DRM before using the device? Fuck that bullshit.
That's a path I'd rather not go down... devices fingerprinting (through checksums or audio watermarks or whatever) the data on them like little spies and doing whatever.
No way in hell. I like my MP3 players to be glorified UMDs (that just so happen to have a headphone jack).
Software RAID will never result in your data becoming unavailable because of failures in infrastructure (other than the disks themselves). Buy two or four drives for your infrastructure server, and set them up as mirrored/striped in the OS. A dead simple proposal with little performance degradation (at least, when using SATA or SCSI).
Although I wouldn't do RAID5 or RAID6 in software. That's what external storage devices are for... full embedded devices with monitoring, support contracts, etc.
I would never willingly purchase a device with such a misfeature. I'm sure I'm not the only one. Way to shoot yourselves in the foot, Microsoft and Apple.
Since version 2.0 they try to push you in the direction of drawing a circle with the path tool (or converting a circular selection to one) and then stroking it with a brush.
Everyone using the GIMP without a tablet should be shown selections, paths, and manipulating them in tutorials, because that's what you're going to spend a lot of time doing if you can't freehand.
GIMP should allow you to: * Undock the "toolbox" from the main application window (file/acquire/prefs menu area, essentially) * Minimize the main application window to a system tray icon on Windows * Allow it to run "widgetless" like a daemon on unix (where opening up an additional image is as easy as running gimp "filename" from a terminal or launched as a result of a GUI file action) * Duplicate the file/etc menus in the right click menu for said system tray icon on Windows
I think something like that would make a lot of people happy.
JFS is one of the better linux filesystems. And while you can't select it in the installer, you can definitely install the tools to support JFS from universe in Kubuntu, and it's similarly available in the Fedora base repositories. The kernels come with the modules pre-built already, so...
And you can shrink and grow them. And it has nice backup and fsck utilities... Oh, and it supports extended attributes and ACLs and all that good stuff. And it's faster than XFS.
It tastes alright... the flavor is a bit too much like sunkist or antifreeze but unfortunately every other non-cola diet drink tastes worse. Why does Pepsi insist their diet drinks have the aftertaste of cough syrup?
Most IT techs doing a fix for "cleaning up" a system would disable any services not absolutely necessary and use tools that would have detected this recording process. I mean, VNC puts an icon in the system tray. I'd recognize it anywhere... kinda fishy... you know?
It just so happened to capture an idiot in action. Valets have been captured taking cars for joyrides. I'm not saying it _doesn't happen_. I'm addressing a relative frequency of occurence and the knowledge disparity.
You can't prevent pictures of a certain type (or prevent certain people from accessing them) without something in place to make a value judgement on everything posted.
Sorry, that doesn't work.
I mean, look at MySpace or Photobucket! These sites are thousands of times worse in terms of hosting stuff of interest to perverts.
It's unfortunate, but if people want to post compromising pictures of themselves or others, they will do it, even if they can't control who downloads them. You can put the blame squarely on the stupid people who decided it would be a good idea to upload them in the first place, if you ask me.

Wrangling those backend tools would require just as much training as learning another system. You need staff to manage Sharepoint effectively.

No more than they can break into current aircraft radios and relay fake orders. *eye roll*
I imagine it's a bit more difficult. I mean, can you break the AES encryption on my laptop? Not even the NSA can.
