Is the App Store Broken?

AC-x "entirely new CPU architecture" ? (235 comments)

"entirely new CPU architecture" ? The A7 uses a 64 bit variant of ARM. If you want a mobile OS that's been ported to completely different CPU architectures then look at Android; It supports ARM, MIPS and x86. They can even run the same apps.

Lots Of People Really Want Slideout-Keyboard Phones: Where Are They?

AC-x Re:Obligatory personal blog remark (540 comments)

Yeah, I hope that's a joke, because I did a survey of people in the smoking area of a bar and found that 19 out of 20 of them smoked. Extrapolated to the population of Earth that makes 6.7 billion smokers...

Do Apple and Google Sabotage Older Phones? What the Graphs Don't Show

AC-x Google did leave my poor Nexus S hobbled (281 comments)

I have to say that Google certainly left my Nexus S in bad shape, they updated it all the way to 4.1.2 which was too resource heavy for it, then didn't update it to 4.2 which contained a bunch of performance improvements that the NS badly needed! I've been on a close to stock custom rom since then, and every major release has improved it until it's now very usable on KitKat.

Obviously in the mean time I upgraded, but it still makes a very usable 2nd phone running KK.

Laser Eye Surgery, Revisited 10 Years Later

AC-x Cyborg eyes (547 comments)

I like to think that my contact lenses give me cyborg eyes (eg. technology that is so integrated with a person that it becomes an extension of their own body, while offering enhanced capabilities) - not only do they give me perfect vision but they're also UV protective :)

Plus I use dailies so I don't have to worry about cleaning or losing them.

Laser Eye Surgery, Revisited 10 Years Later

AC-x Re:"Free" myself from glasses? Huh?! (547 comments)

Can't be doing with contact lenses though. Went for a trial, couldn't even keep my eye open for them to put the test lens in, so that was the end of that. Ugh, actually putting something on to the surface of one's eye? *shudder*

There's a trick I use where instead of going straight for the pupil (damn brain's all like "nope!" and shuts my eyelid), I place it to one side then shift it round a bit. A few blinks later and it's centred itself. Again to take it off I shift it round first before grabbing at it so my eye doesn't see my finger while I'm doing it.

Laser Eye Surgery, Revisited 10 Years Later

AC-x Re:without surgery (547 comments)

Here are tons of smart people, I don't see anybody talking about training eyes - recovering without surgery. but I know that I it is possible to get very good results without altering your body irreversible.

Maybe because all the medical studies done on vision training for myopia have failed to find any evidence that it has any physical effect?

Are you confusing it with vision therapy for eye movement and co-ordination disorders?

AC-x Lost property (547 comments)

I use daily contact lenses so when I lose one it's only around 50p wasted :)

One Trillion Bq Released By Nuclear Debris Removal At Fukushima So Far

AC-x Re:... and that's not much. (190 comments)

1 trillion Bq is about 0.3g worth of Cs-137.

You wouldn't want to swallow it, but it's not going to be "cooking" anything.

One Trillion Bq Released By Nuclear Debris Removal At Fukushima So Far

AC-x Is that all? (190 comments)

Becquerels are tiny units. In the first 3 months after the accident 14 Quadrillion (1.5x10^16) becquerels were released. For comparison Chernobyl released 14 Quintillion (1.4x10^19) becquerels in total. (source).

Compared to that, 1 trillion (1.1x10^12) becquerels is a big improvement in rate of release and according to Wolfram Alpha represents around 300mg of Cs-137.

Mozilla Doubles Down on JPEG Encoding with mozjpeg 2.0

AC-x I'm not convinced webP is better (129 comments)

I'm not convinced webP is better, I've done a quick comparison and to my eyes JPEG beats it on like for like file sizes:

40k jpeg vs 40k webP (images converted to png for your viewing convenience)

Compared to the lossless original (one of Google's own webP comparison images) the webP version has lost more chroma resolution, leading to desaturation in parts and blurring of strong colour details like the red arm band.

It would be nice as a replacement for PNGs with alpha channels though.

New Raspberry Pi Model B+

AC-x Re:Slow CPU, crippled network, too little RAM (202 comments)

The number 1 priority of the Raspberry Pi foundation was a price of $35 and $25 for the 2 models, as that's the price they determined people would pay for a "disposable" computer for kids. Everything else is secondary, that's why all those more powerful clones out there end up costing more.

A Brief History of Patenting the Wheel: What Goes Around Comes Around

AC-x Design patent (36 comments)

US patent D690249, granted on September 24, 2013 to Mark Finnie of La Palma, California, for a “Motorcycle wheel with seven bifurcated spokes”.

But that's a design patent which just protects the cosmetic look of the product, which is perfectly legitimate for designer alloy wheels.

Radical Dual Tilting Blade Helicopter Design Targets Speeds of Over 270mph

AC-x Re:Eurocopter / Airbus X3 (103 comments)

It's more like the Sikorsky X2. The dual rotors are an important feature; With a single rotor as you increase forward speed you lose lift on one side of the rotor as it slower relative airspeed, until it's basically going backwards. Having contra-rotating rotors means that one side will always have blades going "forwards" regardless of airspeed.

New Single Board Computer Lets You Swap Out the CPU and Memory

AC-x Is it really a single board computer? (122 comments)

Is it really a single board computer, if the SoC is on a separate board?

Looks more like a mini, more powerful version of the Raspberry Pi Compute Module with a Raspberry Pi like breakout board.

Those SoC modules themselves could be useful on their own if they sell the sockets to use on custom circuit boards...

Exploiting Wildcards On Linux/Unix

AC-x Re:Who ever asked for this "feature" (215 comments)

Hmm, good point, didn't think of messing around with filenames in a for loop.

* could still use ./ as an escape code just for files beginning with - , that seems to me to be more of a step forward than a step back

Exploiting Wildcards On Linux/Unix

AC-x Re:Computers were conceived to execute user comman (215 comments)

I have no idea what the solution is, but I suspect that we need to do some fundamental rethinking of secure architectures and user interfaces. Architectures need to more safely isolate data and logical functionality, and interfaces need to more safely mediate users interaction with devices. I confidently assert that the current architectures simply can't be secured, no matter how much junk is kludged to the task. Prove me wrong, please.

On the other hand this specific issue could be easily solved by * prefixing all filenames with ./

So far I've not heard of anything that would break, and it's silly arguing that this specific problem is part of required functionality and not something that can/should be fixed when it appears to have such a simple solution.

Exploiting Wildcards On Linux/Unix

AC-x Re:Sanitize crazyness (215 comments)

The problem is that the * expansion is done by the shell, and the shell doesn't know the difference between file names and arguments.

But it could very easily make them explicit filenames by prefixing them with ./, and I can't think of anything that would break.

Famous Judge calls U.S. patent system "dysfunctional"

AC-x AC-x writes  |  more than 2 years ago

AC-x (735297) writes "Famous U.S. Circuit Judge Richard Posner calls patent system "dysfunctional", wants to have the trial between Apple and Google-owned Motorola Mobility over smartphone patents dismissed with prejudice because "it was apparent that neither side could show they had been harmed by the other’s patent infringement".

His involvement and his anti-patent blog posts could prove to be a watershed moment for a U.S. patent system that is regarded as spiralling out of control."
