Except you get much less zoom and enhace with this thing because you reduce your resolution to 10% of the sensor's capability for the sake of the depth of field control. A 40mp sensor turns into a 4 mp one. A face 100 pixels wide on an image is useful. A face that's 10 pixels wide, rather less so.

For CSI you'd want the near opposite of this camera: high resolution, a small aperture to keep everything at once in focus, focused to infinity, and excellent low ISO performance to compensate for the small aperture.

- Yes it is $1600 and 4MP. Do you know how much the first DSLRs were with only 1MP? Technology evolves.

The problem is that physics get in the way of resolution increases, and the best modern DSLRs already have a sensor that can out-resolve most lenses.

Which means that a Lytro style camera is going to necessarily sacrifice quality.

You can make a larger sensor, but that costs serious $$$. This thing is in the price range of a full frame camera. If I'm guessing right, to compete in quality with a normal one it'd have to go with a medium format sensor, and those start at around $10K.

- Why do you need interchangeable lenses when you can focus on or apply lens effects on whatever you want after the fact? You would not care about lenses with this kind of technology at all - in fact, the elimination of lenses means this technology could result in large cost savings over the long haul.

Because lenses have nothing to do with focusing? All lenses can focus at all ranges. You can't put a f/1.4 on this for shallower depth of field and better low light performance, or a 10mm wide angle, or a fish eye, or a better telephoto lens, or a tilt/shift for architecture.

It could however be very cool for macro, but oddly enough they don't seem to be hurrying to demonstrate that. Which is a pity -- extreme macro is a huge pain to focus, and that's the one area where this thing could show some promise.

It's mostly a solution in search of a problem.

Photographers choose what to focus on very intentionally, it rarely makes sense to focus on anything else. Of course it's possible to misfocus, but in that case it makes no sense to let the user play with it.

It's still going to be low res, because you get a small fraction of the "megarays" the sensor provides. The spec for this camera was 40, IIRC, so it might get around 4MP, which can't really compete with a modern DSLR. While resolution isn't everything, having some margin for cropping and large prints is a very good thing.

The control for the interactive photos is still clunky. I can't find a way to for instance get the whole image in focus, though that should be possible. It does it while changing perspective.

It doesn't fix the other problem that leads to blurriness -- camera shake. It's all well and good to be able to refocus, but most people learn to focus right pretty fast. The problem is with low light environments, and this isn't going to save you if you handhold and shoot at 1/10.

The sample images still looks low res and blurry.

It costs $1600 and doesn't seem to have interchangeable lenses -- what, are they insane?

Overall interesting toy, but doesn't seem to have a practical use.

The Linus/systemd controvery is long over btw. People had a conflict, yelled a bit at each other, then came up with patches, and everything went back to normal.

Personally I like at least the idea of systemd. It means I can make a single startup script, and have most of the work done by the system, instead of having to muck around with the minor differences of the ubuntu/debian/etc scripts.

Let me translate. They were fucking off by diverging from the core project into recreational political activities unrelated to their mission.

But that seems to be what a lot of people on Slashdot want. Look at the Mozilla and DropBox controversies. Lots of people posting and moderating support those.

No, I'd say what people here want in general is for an organization to be apolitical. Being against LGBT is bad, but doing activities related to LGBT is also bad. A software company is supposed to be a bunch of people coding and nothing else, ideally.

I have DK1 and ordered DK2.

DK1 is cool as a prototype, but the lack of positioning gets annoying at times, and the resolution is horrible.

DK2 fixes that, but it sounds like the resolution still needs improving.

This is the kind of thing I'd love to have in there. The Rift as it stands right now won't work well with many UIs, as it's too low res to render the details, and it seriously breaks immersion to see things pixellated.

So the more the better I say, if it's overkill for a phone then there are other uses for it.

Global menus

Mac OS has been like this since System 1. And it makes sense; whatever you're doing, its menu is going to be in the same place. Fitts' law indicates that the most quickly accessed targets on any computer display are the four corners of the screen.

Single mouse click

Mac OS has supported multiple mouse buttons for at least 16 years. Even when using a now-extinct one button mouse, control-click presented a dialogue box.

Left window controls (yay for all the left handed and left eye dominant people, boo for the other 95% of the world)

Because it's easier to move a mouse up/left with your right hand, and was developed in a country that reads left-to-right.

Launchpad (how is the start menu missing causing a revolt and launchpad even exist? Launchpad is the initial SIN!)

The start menu missing is causing a revolt because Microsoft removed something and replaced it with an abomination. Launchpad - and other questionable features like Dashboard - can be completely ignored.

Finder layout straight out of system commander circa 1988.

Column view in Finder is optional, with icon and list view still available. Also, Finder has had its sorting options greatly improved throughout OS X's history.

Crap loads of docked icons you never use be default.

If you go and buy a Mac today, this is in the Dock:
- Finder: File management
- Launchpad: Access to all apps not in the Dock (And easily ignored, as previously discussed)
- Safari: A web browser
- Mail: Email client
- Contacts: An address book
- Calendar: A calendar
- Notes: Short notes
- Maps: A map of the entire planet
- Messages: Text messaging and IM
- FaceTime: Video chat
- Photo Booth: Something fun to play with on your new computer
- iPhoto: Something to talk to your camera
- Pages: Word processing
- Numbers: Spreadsheets
- Keynote: Presentations
- iTunes: Play and purchase music and TV/movies
- iBooks: Read and purchase books
- App Store: Install and purchase software
- System Preferences: Change settings on your computer

The default Dock icons cover managing your computer, using the big two features of the Internet, syncing 'organisational' information with your phone, finding locations, messaging and video chatting with other people, photography, writing, processing numbers, creating presentations, watching media, reading, and installing an app to do anything else you want your computer to do. The default Dock is a slam-dunk for covering what the majority of people use computers for, points users in the right direction to add new capabilities to the computer, and is easily customised to remove the things you don't want. (Launchpad, again...)

The Dock is setup perfectly for you to get started with your computer. Anything else you need to get to can either be accessed through Spotlight (power users) or Launchpad (for people with more experience with iOS).

A separate contact and calendar app....

Just like iOS... but also NeXTSTEP; they have always been separate apps, which makes finding what are ultimately different tasks easier *and* they also seamlessly share the same databases behind the scenes.

General iOS crap

Integration with touchpads is great. Removing always-visible scrollbars removes needless clutter. Things like Launchpad - and pretty much anything else you don't like that reminds you of iOS - are easily disabled or ignored.

Hardwired application dependency locations (the whole point of application folders is to stop that!)

Wait, what? Apps install into /Applications by default, but the system works just fine with app in ~/Applications. Beyond that, moving apps around is making things needlessly complicated for yourself. Even then, the vast majority of apps are self-contained bundles and can be run from anywhere.

Scroll bars that disappear even if your mouse is near them and appear at the bottoms of pages OVERTOP content.

Touched on this in iOS; the scroll bars appear when moving the cursor or scrolling content. If you find this to be an issue, it can be disabled in System Preferences. Yes, Apple provided sensible options!

I could go on and complain about the apps, but lets say OSX is great for people who use a computer like they use iOS and leave it at that....

It's a mature system with 13 years of refinement, and is built for use on 'real' computers. iOS features have only gone "back to the Mac" since 10.7, and even then - as previously discussed - are all avoidable if found that unpalatable. OS X is also bundled with apps that over most use cases for a personal computer, and installing developer tools is simply a matter of typing 'Xcode' into the App Store.

OS X is the current gold standard in desktop operating systems. It's incredibly well thought out, and that's why Canonical, GNOME, and others keep looking to it for guidance. However, it was foolish for Ubuntu to unexpectedly drop application menus for global menus after nine years without presenting an option to switch back. And that's the difference between OS X and Ubuntu; Apple wouldn't make such a ridiculous and far-reaching change to the system without either an option to disable it or an incredibly good rationalisation.

Spying on this level isn't needed for when secret services "take an interest in somebody". There already are mechanisms for the authorities to wiretap you if they're concerned with you directly. There's no need to wiretap the entire net for that.

No, the purpose of such things is to assemble large databases of things like who talks to who, and for those purposes, you are of interest to secret services, as is everybody else. Let's say a friend of yours participates in some sort of environmental activism. Well, you both communicate, and that automatically makes you a person of interest.

+ - Former Dev Gives Gloomy Outlook on Linux Support for the Opera Browser->

Submitted by Anonymous Coward
An anonymous reader writes "It doesn't take a Columbo to figure out that the "previous employer, a small browser vendor that decided to abandon its own rendering engine and browser stack" is referring to Opera in this comment answering the question "Do you actually use the product you are working on?". It appears to originate from Andreas Tolfsen, former Opera developer and now part of the Mozilla project.

From releasing a unified architecture browser including Linux support since 2001, Opera decided to put Linux development on indefinite hold, communicated through blog comments, and focus on Windows and Mac for their browser rewrite centered around the Blink engine that had its first beta release last spring. The promise to bring back the Linux version in due time was met with growing skepsis as the months went by, and clear answers have been avoided in the developer blog. The uncertainty has spawned user projects such as Otter browser in an attempt to recreate the Opera UI in a free application.

Tolfsen's statement seem to be in line with what users have suspected all along: Opera for Linux is not something for the near future."
