Your UID tells me you've been reading slashdot for at least 15 years, surely you remember how ad blockers worked back in the day? Most inline adverts were trivially identifiable (and successfully blocked) by their pixel dimensions or position on the page. Toss in some crowd sourcing to identify anything that falls through the gaps and it's a solved problem.
Feature request: Change User ID.
I don't mind if it's restricted in some way, once a week, month, year, etc., I really would like the ability to change my user ID though.
I would also like to see ponies return once in a while, and I want a lower UID
Wireless devices - I think you mean point to point microwave communication systems. The majority of entries in the list are for unlicensed equipment, equipment that doesn't frequency hop away from active radar emitters, or equipment modified to operate on unlicensed frequencies. They might be wireless, but they aren't WiFi, nor are they radiating less than 100mW. These are outputting anywhere from several watts through to kilowatts.
Although the impact is a little indirect, medical imaging systems are often rate limited by the hard drive. (When they aren't hamstrung by network speed that is) Frame rates are more a measure of how quickly you can scroll through the image stacks - the scanners themselves don't actually give you an 'image', they give you a bunch of instance objects that can potentially contain a few thousand parameters each - a subset of these within each object define how the pixel data will be interpreted to generate image data appropriate for the display depth.
You might have a 3000 image CT because the tech sent the raw acquisition rather than the more pertinent diagnostic sections, the radiologist expects to be able to scroll these very large stacks end to end ideally in one or two mouse movements - and they want to see every single image as that happens too. You don't always have enough RAM to store the entire data set so you have to load it from the hard drive as needed - then parse it out. Even when a study does fit in RAM the rad will usually have one or two series dragged over to the viewports a fraction of a second after the thumbnail has rendered - they are already flicking at the scroll wheel waiting for some business to happen, behind the scenes the image loader is still asking the PACS for a list of instance UID's and the path to the raw data because WADO is too slow
No matter how fast the hardware is, there's always some inefficiency that people notice. Within an emergency room setting these delays can sometimes be costly.
Which is unfortunate because there's nothing special about WiFi, satellite networks have been using the same (and vastly more complex) modulation methods for decades.
9 years ago I typed my name in to the JPL website (I think it was JPL) along with 434737 others, these were added to a CD and attached to the probe. Kind of cool thinking a few bits of all that data are mine. Even if it's just a fly by, it's still pretty awesome. Unless future humans venture out after it, it's never coming back our way, for me this seems just as worthwhile as if it had fuel enough to slow down and place itself in orbit.
From the Ubuntu website, (serverFaq) the only listed security concern seems to be that 'people might try and brute force the root password if the account is enabled', all other reasons are administrative. It's not highly discouraged, it's just a different approach.
Seems quite logical that someone would have been looking at the area, though the Indian ocean is a massive expanse of absolutely nothing but water. Generally speaking most LEO birds would have been in darkness for most of the flights duration in that region - I would humbly suggest another possibility would be that spy satellite operators take that as an opportunity to conserve power by shutting down EW kit, it is probable nothing was picked up at all - then again, why build a satellite that could pick up transmissions intended for Inmarsat when Inmarsat could just do that for you on request? (I'm not suggesting they actually do, but they certainly could)
If you tune through the HF band you can hear OTH radar active pretty much 24/7 - seems like that'd be the most probable system to have detected anything. Early on there was a suggestion that one of the pilots cell phones contacted a tower - seems like most people jumped on wiki and concluded this wouldn't work given the range of the system, or that the fuselage would block the transmission - if you delve a bit deeper in to the GSM spec., the distance from the tower would prevent the phone registering on the network due to the nature of TDMA, but it doesn't mean they didn't communicate with the base station controller at all.
Maybe in 30 or 40 years some 3 letter agency will declassify a mostly redacted but still interesting story...
Think bigger than just the Ocean. The general consensus is that it went south, the inmarsat data alone certainly points toward a southern track, but some of that data is based on assumptions about hardware calibration - the data alone does not rule out the possibility of a northern flight path no matter how remote. I'm a former Australian 3 letter agency drone, I have no additional insight on this than anyone else, though I do have a rather solid background in electromagnetic radiation.
Maybe some day a seat cushion will wash up on a beach, or someone motorbiking in northern china or climbing mountains in one of the 'stan' countries will trip over an aileron or something. I certainly hope so anyway, just so the families can get closure at the very least - might be some lessons in it for the aviation sector as well.
From the website you linked - in reference to the shim.... Seriously?! Which part of that doesn't take a month to understand for someone that just wants to zip down to staples and grab a laptop with the expectation the install media will "just work" like it always has done for the last decade?
To use it, rename shim.efi to bootx64.efi and put it in
Now generate a certificate and put the public half as a binary DER file somewhere on your install media. On boot, the end-user will be prompted with a 10-second countdown and a menu. Choose "Enroll key from disk" and then browse the filesystem to select the key and follow the enrolment prompts. Any bootloader signed with that key will then be trusted by shim, so you probably want to make sure that your grubx64.efi image is signed with it.

There is a decent chunk of compute power in the controllers.
I'm not sure about games, though I build web based medical imaging systems for a living these days, along with a whole slew of related information systems. DICOM objects are decoded fully in the browser and render on canvas almost as fast as they do in native applications - this includes features like window level, stack scrolling, X, localizer lines, multiple viewports, and a myriad of other computationally expensive features. Managing memory is the most chalenging aspect by far.
In simplistic terms, it's what people want, all they have to do is open a web browser and they have the latest version.
