Swap is not optional if you're going to use leaky software (like for instance browse the web) on a linux machine for long periods of time without rebooting. Firefox or Chrome can easily grow to 4 or 8 gigs over time if you don't have a swap partition. If you have 16+ gigs of RAM on your machine you might not need swap at this time, but as web sites become ever more bloated you will need to upgrade to more RAM or get a swap partition or swap file.

While Linux kernel is solid on servers for whatever reason on desktop it always was crashing and/or required occasional reboots. Flashdisks plugging/unplugging creates allocated un-unmountable devices. Desktop machines just randomly reboot. Screen occasionally goes black or garbage forever (it may be X bug). Keyboard becomes unresponsible. OOM problems where the system locks up or some fundamental process gets killed. etc.

Do you have a swap partition and is it reasonably large? A lot of strange stuff can happen if you decide you don't need a swap partition (think again), or if you use a really small swap partition, i.e. 2GB.

Permissions on Android are a bit more rudimentary, so it would be simple to make a background process that just sits and quietly listens to the gyro. You would need to ask for the permission to keep the device awake in order to keep the CPU and sensor chip alive and (in order for it to be practical) the permission to start on boot.

Basically an app can ask for permissions for the gyro only (if it even needs to) and be recording conversation.

Yeah, that's the thing. You don't need permissions for the gyro on Android and iOS, so any and all of the apps that you have on your phone or tablet could be using the gyro and you wouldn't know, except for an anomalous battery drain.

TFA says adding 1 mm of aluminium to the wheels would have added too much weight to the wheels. Silicon rubber is about half as dense as aluminium, so a couple of millimeters of that would also have been too heavy.

There are probably lots of other ways to improve durability, like for instance by making the chevrons on the wheels slightly less pointy.

1. That seems overly drastic. The flashlight apps are useful and kids love those silly apps. The solution might be to add more categories and force apps into the correct category.
2. What? No, that would be horrible. The definition of a smartphone used to be a phone that lets you replace some of its stock apps with custom apps.
3. That is actually a great idea.
4. That would kill something like 95% of the serious app businesses.
5. Yes, again that is a good idea.
6. This might be necessary in order to comply with regulation in many countries, but it would not be very useful in practice in most cases. It would lead to things like...

You'd think these cars would have a sensor in the seat to detect if there's a driver or not.
I mean, newish cars already have them in the passenger seat to enable/disable the passenger side air bags.

They would need something better than that, like a camera that monitors the eyes of the driver and correlates the eye movements with the road and the traffic to determine if the driver is actively aware of the situation.

One solution might be to have cars that are always in one of two modes:

Mode 1: Fully autonomous.
Mode 2: Fully manual. A warning signal will sound if the driver does something that the computer wouldn't do, or fails to do something that the computer would do. The computer may decide to switch to mode 1 if it determines that the driver is asleep or drunk.

Why is it our media (even this post) always seems to portray Hamas in a positive light?

This conflict would end the SECOND Hamas stopped their aggression. The moment Hamas stops shooting, IDF stops shooting, period. Hamas lies and has no moral honor, they betray everything, and want nothing less than to wipe other people off the face of the earth. How is that humanitarian and moral? And yet the western media doesn't portray that side of the story!

Your naivete would be cute if it wasn't for all the dead children!

Israel will not stop when Hamas stops firing rockets. I suspect Israel will stop the slaughter the moment when the Palestinians cede ownership of their natural gas fields to Israel for free.

Also, how do you know these things about Hamas if the medias doesn't cover it? Of course the media covers Hamas's acts of terror. The part that is lacking is the fact that vast majority of Hamas's terror is aimed at Palestinians who belong to rival factions or who don't pay their protection dues on time.

I forgot: If Israel nukes Gaza, they would in effect nuke them selves. It's like New Jersey nuking New York.

Israel's nuclear weapons are likely to be fission or hydrogen bombs in the 50-500 kt range. These bombs would not harm anyone in Israel if they were dropped on the main population centers inside Gaza. There might be a tiny bit of fallout, but nothing too serious.

New Jersey and New York are closer to one another, but you could still nuke central Jersey City without seriously injuring many people in New York if you used a 100 kt bomb. Window panes would be in high demand on Manhattan following the strike and many people would have superficial wounds from shattered glass. A tiny number of people on Manhattan might die on streets and sidewalks in accidents involving unusually aerodynamic pieces of shattered glass falling from tall buildings.

I don't recharge every night. I get a good night's sleep maybe twice a week my phone should be able to do at least as well.

Seeing as several phones I have owned have lasted on a full charge for days if not weeks that is not an unreasonable expectation for the average smart phone to live up to.

The average Android Phone actually does live up to this if you set the backlight to the lowest setting, turn off WiFi and uninstall any apps that launch background services. Turning off WiFi and removing apps that do stuff automatically pretty much renders it not a smartphone, but you do get good battery life.
