Just get the old Moto G 4G (LTE), which has a micro SD slot then. But it costs something like 199$.

To kill the screen latency, you could use Miracast, which seems to be much faster than the chromecast (see https://www.youtube.com/watch?v=J-5JJhKMph8) or connect a cable (best solution: no heat because of the video encoding, can recharge the phone with MHL, no lag). Also one issue would be the DPI. Working with the big android elements on a, say, 24 inch screen would be a pain. But maybe you could automate a DPI change to rescale the whole interface.

Yep, I think the A8 (or A7X) could be really close to the performances of entry level CPUs used in MacBook air! An A7 scores 2564 and an i3-3217U 3095. But if you look at the Atom Bay Trail, which scores 2630, you see that Intel did a nice coming back in the mobile segment, at least for tablets.

In the case of a quad cortex A7, like the one in the Moto G, or the MediaTek MT6589 in the bench comparison, we see that the performances are too bad to replace a laptop. With a score of 1258 it is comparable of the best good old netbooks with Intel Atom.

Wow, I installed Windows 8 on a T7100 (1.8Ghz) and it runs super smoothly, but some people were complaining of Tegra 3 windows RT tablet being slow? (try googling "tegra 3 windows RT slow") That is weird! Can we really trust those benchmark for real day to day comparison? Or maybe I don't have the same speed expectation as the tablet users?

Lesson to learn: don't tie down your service and/or brand to an existing brand/service. Otherwise you're both dependent of that service and/or at risk to get sued sooner or later.

Yes! And also you can take it with you to take notes efficiently with your phone/tablet at school/conference! One keyboard for all you devices, so you don't have to buy multiple ones or get used to each keyboard. This is brilliant! All of this just with a switch, without any re-pairing!

Wow, so does all the processing happen on the phone itself? That's impressive! I thought it was sent on a server to be processed.

Maybe I got brainwashed by their video, but I indeed think that a laptop like the Dell Latitude 13 (http://youtu.be/rq5dqKWymP8) is much better than a tablet.

There is a keyboard, a network activity light on the back of the screen, removable battery, spill resistance, compatible with the Dell Mobile Computing Cart to store and charge them, the laptop can open flat and has a touchscreen so it can do all what a windows table can, 8H battery life, USB ports, they claim that it's sturdy. But most important, there is a keyboard! And with the new features of windows 8 where you can reset the computer with factory settings with or without keeping your data, that's good, but still not as good as not being able to have any software problem like on an iPad.

I really like the network indicator on the back so that the student is immediately spotted when going online, nice idea.

Do you need to be on the same local network as the user to do that or does that work with an attacker being on the internet?

Sure enough, that's a real problem when the attacker is on the local network, but what if the attacker is not on the local network? Because I think that this attack is supposed to work from an external network, or the Internet.

I meant to say "share files" instead of "share data". But you're right, as I said, "Please correct me if I'm wrong". What I really wanted to say is that USB has been designed with so many different usages in mind that if you plug something in it, you should expect this "something" to be doing anything the USB has been designed for. And if you only want to share files and be sure it's not doing anything else, maybe you shouldn't be using USB. But at least this "problem" with USB is not as bad as with firewire or thunderbolt external storage.

At least one of the attack, the CSRF on the Asus RT-N56U, seems to need the IP address of the router. Does this mean that this attack is useless when the attacker doesn't know the IP of the router? Or is there a way to know it remotely? (I happen to have this router and the IP of the router is not the same, and I don't think that the default config has been changed as the admin interface has the default password.)

Also, an attack necessitating a user to be logged in to the admin interface has probably a very small chance of success. I don't know any "normal" person who would log into their router admin interface (unless maybe they are asked for with social engineering).

PS: but having an Open Wireless Router is a good idea anyway. We could imagine one having upgradeable hardware and just switch the mini PCIe card to have 802.11 ac instead of 802.11 n for instance.

First of all, I think the title has been chosen to click-bait the reader. Second, maybe the real problem is that USB was never designed to be the main way to physically share data, or not even to be used with external storage? Please correct me if I'm wrong. Maybe people should start exchanging data on media that are designed to store data, like a memory card, but maybe this medium can also be compromised.

Why are most of the lithium cells cylindrical, while most of our devices are cuboid? (I think of phones, laptops, external battries... but phones and most laptops have flat lithium cells nowadays). Is cylindrical less expensive? Is it more secure? It seems like a waste of space to me.

Oh god, I tried to read the screenshots to have an idea of what is the service like, but I gave up after the second time being interrupted by the carousel. Terrible.

Okay, thanks for the explanation on the chroma upsampling! I use Linux but it should work all the same.

When I said that I embedded the videos in a web page, I wrote a small page from scratch to display them in my browser, locally, without any server. So no re-encoding. I think that VLC just has a better chroma upsampling.

Thank you! I was gonna post the exact same thing. Nice website, though.

I encoded the gif in 420 (subsampling), 422 and 444, having a nice quality with 444 with VLC, I embed the three different videos in a web page and when playing in my browser, they are all as bad as the twitter video! I thought that Firefox was using a standard library to play MP4?

Sorry but H264 does not use JPEG for its keyframes, although it's not very different. There are a lot of differences between GIF and H264, like H264 specifies that you can use multiple reference frames, which is not the case with Animated GIF. Also H264 has motion compensation, which does not exist with GIF.

GIF basically rewrites completely a part of the picture, while the remaining part is reused. And if you consider that a rewrite of a small part of the frame to reuse the remaining part from the previous frame is just displaying a new gif on top of a part of the old one, the you can consider that it is a sequence of independent images. Maybe they don't all have the same size and are not meant to be displayed at the same position, but they are independent in the sense that you don't need a previous or future frame to display one frame.

And I wouldn't refer to GIF as lossless, except maybe if your original animation used only 256 simultaneous colors per frame. You lose information by down-sampling your colors.

Did you see that it is only stabilizing rotation? If it looks so stable that's because the lens of the iPhone is at the exact center of the wheel. If you were to move your phone along a X or Y axis, I don't think those movements would be stabilized like you could get with a software stabilizer. I guess the main target of this app is people turning their device when shooting a video.

Yep, I was pretty disappointed. I expected to learn more on the startup scene in Berlin, but the introduction and first two paragraphs are about him. The title should be more "I'm an awesome startup entrepreneur and I'm gonna teach those foreigners how we do it in SF. Because they don't know how to startup. And I kick asses."

I may be a nitpicker, but for me 4k is 4096x2160, or am I wrong? This screen is UHD, or 2160p but not 4k.

Stamps on a passport is actually a pretty good example on what one would like to hide from the authorities even though he didn't do anything wrong. I say that as an answer to people like Eric Schmidt who say that if we have something to hide, we shouldn't have done it in the first place. Well, that would be true in a perfect world, but here we have a perfect example that it's not the case. So for this case, I would also advise having multiple passports.

Even though your statement is not necessarily true, I bought a Vaio T11 almost two years ago and I was able to upgrade the SSD (the laptop has the footprint of the 11" MacBook air) and I have a HDD (in addition to the SSD), that I can upgrade very easily, I also had a free SoDIMM slot and was able to double the ram from 4GB to 8GB. That's what I like about PCs. Here with the mac you only have one drive that you cannot change or upgrade and the ram is soldered.

Amazing work, I didn't know there was a complete linux system on this! I guess it's cheaper than having a custom hardware.

Potential use case: turn a simple printer equipped with an sd-card slot (to print photos directly on the printer) into a manual wifi printer. The job would be converted to, say, jpeg, sent on the sd-card and then you would have to print it manually.

Other use case: be able to send any file to this SD card, this way you could easily transfer pictures, videos and music to a non WiFi multimedia device, like a TV Tuner, MP3 Player, etc...

It may be related to Intel's drivers, as I am playing Team Fortress 2 on Linux, which is I believe native OpenGL, and it is significantly slower than on Windows with an intel GPU.

If you look carefully you'll notice that the only difference between the $299 monitors and the Ultra HD monitor in term of design is a thinner bezel. Maybe it would have increased the price much more for virtually nothing to have a thinner bezel on their new screen. Also, they don't have any competitor for this screen, so they don't need to distinguish themselves from the competition like they do with the "borderless" 24" screen.

I personally don't find them cheap looking and I'd rather have a "plastic" looking bezel with a mate screen over a sleek looking screen with an all-glass shiny front.

I didn't see it in the release notes, but the last version of Bluez (bluetooth) is finally supported! http://worldofgnome.org/gnome-3-10-port-to-bluez-5/
