Any good alternatives for this very useful app?
Qiasfah··on Is it illegal to own a rabbit in Queensland unless you're a magician?
Importing animals of any type into Australia isn't easy since they don't have many of the diseases on other continents, nor would they likely ever approve this for non-native species.

Rabbits are a huge problem in regards to protecting the native marsupials.

Australia's attitude towards rabbits is completely different than areas where they're native because they are such pests.

Qiasfah··on You’re an Adult. Your Brain, Not So Much
Changing the legal age in this manner would have had serious negative effects on my life. Frankly this idea horrifies me.

Let me explain:

-A job I had in highschool enabled me to buy my own car and pay for insurance at 17 (added as a driver to my parents plan of course).

-I got my first credit card at 18 when I went to college, I have never carried a balance on it month to month (I'm now 26)

-The last time I lived with my parents was the summer after my freshmen year in college

-I graduated with an engineering degree at the age of 21

-I've had a steady fulfilling engineering job for 4.5 years since graduation

-I met my current wife freshmen year of college and we got married a year after graduation

-In 2014 I bought a house based purely of my personal credit history and employment status

-I have voted in every presidential election despite not being actively involved in politics

I'm sure I fall well outside the typical statistics for someone of my age, and I've been very lucky so far. Lots of my coworkers are in a similar situation as me, but there's also lots of people in the opposite situation.

Do you see why this horrifies me? Do you think these ideas would be positive for the young adults that have found success in life?

Have you tried disabling the apps instead of uninstalling them?

I've had good luck with this on stock roms when you can't uninstall the carrier's apps. Settings » Apps » All » Application Name » Disable

Technically the app is still there, but it can't be launched and doesn't appear in the list of apps.

Qiasfah··on Nano-enhanced textiles clean themselves with light
"When the nanostructures are exposed to light, they receive an energy boost that creates "hot electrons". These "hot electrons" release a burst of energy that enables the nanostructures to degrade organic matter."

Organic matter, like our skin?

Qiasfah··on Lenovo Launches ThinkPad X1 Yoga at CES with OLED Display
"but for some unknown reasons most brands keep making changes to the layout with every model"

The thinkpad keyboard layout has been consistent as of late. The T460(s) keyboard layout is the same as the T450(s) keyboard, which is the same as the T440(s) layout, which is almost the same as the T430(s) layout with minor differences in the function keys.

These thinkpads are not an example of a brand changing the layout every model.

Does the city own its electric company?

This was part of the selection in a lot of the cities, since fiber can be run alongside existing electric supply lines.

I notice that they're using a 500GB 5400RPM boot drive.

Is there a need for that large of a boot drive? I would have expected that an SSD boot drive would be preferable.

This is unlikely considering you only have access to the external power supply. As Dave notes there is a filtering stage on the PCB to help isolate the chip.
Qiasfah··on Why movies look weird at 48fps, and games are better at 60fps
There's some discussion of it at the beginning of this article: http://www.ni.com/white-paper/10669/en/
Qiasfah··on Why movies look weird at 48fps, and games are better at 60fps
Most serious FPS gamers swear by screens that have a higher update rate than 60hz.

In the past this was achieved by setting your CRT to a low resolution and upping the refresh rate. More recently you can get TN LCD panels that offer 120 or 144hz update rates.

Moving the mouse in small quick circles on a 144hz screen compared to a 60hz screen is a very different experience. On a 60hz screen you can see distinct points in the circle where the cursor gets drawn. With 144hz you can still see the same effect if you go fast enough, but it is way smoother.

This makes a huge difference for being able to perceive fast paced movements in twitch style games and is the reason there has been a shift to these monitors across every competitive shooter.

My thoughts on this is that this behavior is similar to signal sampling theorems. Specifically the Nyquist theorem talks about how you have to sample at at least 2x the max frequency of a signal to accurately represent the frequency. For signal generation this means that you have to generate a signal at at least twice the rate of the max frequency you want to display. If you want to accurately reconstruct the shape of that signal you need 10x the max frequency (for example two samples in one period of a sine wave makes it look like a sawtooth wave, ten samples makes it look like a sine wave).

So, if you're moving your mouse cursor quickly on a screen or playing a game with fast paced model movement even if your eyes can only really sample at something like 50-100hz the ideal monitor frequency might be 1000hz. There's a lot of complexity throughout the system before we can get anything close to this (game engines being able to run at that high of a framerate, video interfaces with enough bandwidth to drive that high of a framerate, monitor technology being able to switch the crystals that fast, etc.).

Yes, 48fps movies typically look less cinematic, but I think this is a flaw in movie making technology and not of the framerate. The fight scenes in the hobbit sometimes look fake because you can start to tell how they aren't actually beating up the other person. This detail is lost at 24fps and is why they have been able to use these techniques.

Do any of these stations get busy enough during peak hours so that you have to wait in line for a charging spot?

This happens even at gas stations, but at least you don't have to wait 20 minutes!

Qiasfah··on Recovering deleted files using only grep
That forensic article is a consequence of what I was referring to.

When you delete a file on a mechanical hard drive the physical contents of the file still exist on disk, so you can use tricks like these to recover deleted data.

When the drive is then told to write over these locations it doesn't matter that there is old data there and it writes the new data to the location.

SSDs however store data in pages, and while they can write directly to an empty page they can not write directly to a page that already has data in it. Instead, an SSD has to read the current data from the page, modify that data with the new data that it wants to be there, and write the new data to the whole page at once. This is called a read-modify-write operation and is a major reason why SSDs (even now) decrease in performance as they fill up.

The issue is that when you delete a file on disk there is no way for the SSD to know that those data blocks aren't important anymore (without TRIM). The controller of the SSD has to manage a full drive of data (even if you're only actually using some percent of it) and only figures out that a file was deleted when it is finally told to write something else to that location.

TRIM tells the SSD that a file was removed and allows a controller to recover that area to help maintain its performance.

There is a really good discussion of this topic in this article from way back in 2009: http://www.anandtech.com/show/2829

I guess it's a good thing he didn't have an SSD and TRIM enabled!
Qiasfah··on Superhot game
The demo is nice, but it will probably be relegated to a single player experience.

How could they implement co-op or online multiplayer?

These features turn a game from something that you play once or twice for a few hours into something you keep coming back to.

Qiasfah··on And then...silence
I would guess that the need to "root out" the people who do not have constructive things to say will ultimately hurt the site more than it helps it. The editor shouldn't feel any need to moderate the posts through deletion but rather should focus on using comments to build the community. Stressing on the negative misses the points to the positive.
