megalodon··on How to steal a developer's local database
This write-up by CitizenLab [1] describes the Trident iOS exploit chain. Excerpt:

CVE-2016-4657 [2]: Visiting a maliciously crafted website may lead to arbitrary code execution

CVE-2016-4655 [3]: An application may be able to disclose kernel memory

CVE-2016-4656 [4]: An application may be able to execute arbitrary code with kernel privileges

megalodon··on EmDrive: Nasa paper has finally passed peer review
> Dismissing it out of hand does a disservice to all those people.

Or maybe they all know its impossible, but continue because they are perfectly happy with the amount of funding thrown at them. Not saying it's true, but it's the other side of the coin.

megalodon··on Planet Found in Habitable Zone Around Nearest Star
Assuming the recently announced deep space travel project [1] works out and their estimates are correct (unlikely), it would take 20 years of preparation + 20 years of travel + 4 years of data transfer.

Also mentioned in [1] is that if Voyager 1 was headed for Alpha Centauri it would take 70,000 years.

megalodon··on Bill Gates Interview (1993)
Have you read the guidelines?

This paragraph has been there as far as I can remember.

megalodon··on WebAssembly Specification Prototype
You seem to know a bit about web standards, was minification ever formally accepted by the W3C or did it just happen?
megalodon··on WebAssembly Specification Prototype
I just hope that when it happens we will be able to view and read the source of WASM in the same way we can with javascript now. This is one of the foundations of WWW, please don't turn it into a closed source app store.
megalodon··on Your Phone Has an FM Chip. So Why Can’t You Listen to the Radio?
Thanks for the warning, will not visit Wired again. Auto-play video ads, anti-adblock screens and clickbaity, capitalized titles are all diseases of the "modern" web and should be dealt with accordingly.
megalodon··on Open source is a life changer
Feels like a clever combination of an ad and a CV, masked as a praise for open source.
megalodon··on Has Physics Gotten Something Really Important Really Wrong?
I think you are generalising my comment quite a bit, it was just a reaction to the poster above.

We are never "done", that's kind of the point I was trying to convey. I completely agree that we should use science to help us deal with our current problems. Once we understand more about our world and ourselves, we will automatically get better at solving them. I'm just against the whole short-term, instant results way of thinking.

megalodon··on Has Physics Gotten Something Really Important Really Wrong?
I'm sure most theoretical physicists would call themselves mathematicians. I don't agree physics should favour creating testable predictive models, because who are we to say what's testable in the future? Take the theory of relativity, for example. Would you have stopped Einstein et al from researching it, just because it wasn't testable at the time?

In my opinion, physics is and has always been about answering the big questions, the how's, the why's of our existence. That new technology sometimes comes out of it is a bonus, not the ultimate goal.

megalodon··on Jailbreaking the Microsoft Fitness Band
It is most certainly not a waste of time! According to a recently published article [1], researchers managed to crack ATM PINs with 80-percent accuracy on the first try using the motion sensors on smartwatches.

megalodon··on Show HN: OpenGL in super slow motion – visualising Z-buffering
Are you by any chance comfortable with sharing your thesis here (if you still have it around)? It sounds interesting. I would have asked via email if I had known where to send it!
megalodon··on Show HN: Neural network OCR in JavaScript
Made this roughly a year ago (see https://news.ycombinator.com/item?id=9652913).

Originally I let the neural net output a charcode array (either 4 or 8 bits, depending on if the output was a number or a character) which could then be converted into the corresponding character. In short, this improved performance and decreased accuracy. I ended up switching back to standard mapping (index of maximum probability is the best guess), which requires an output layer the same size as the amount of characters one wants to recognize.

Posted it here again because the demand for this kind of tool still seems to be quite high and there is no FOSS alternative that I know of.

If you have questions or suggestions, let me know!

megalodon··on Exercise Releases Brain-Healthy Protein
I'm not an expert, but jogging every day for an hour seems excessive. Running for half an hour (~5km) 3 times a week will get you a long way and it is one of the best exercises there is. I'd argue it's better than weightlifting because you activate (almost) the whole body and it's free.
megalodon··on The “Cobra Effect” that is disabling paste on password fields
Okay, wow. Just clicked the https://www.bankid.no/en/ link and it looks like it's two entirely different companies using the same name?

In Sweden we use https://www.bankid.com/en/ which doesn't use SMS for authentication, it's mobile app based.

megalodon··on The “Cobra Effect” that is disabling paste on password fields
You are probably right, I added that part in because I read somewhere that not all countries maintain lists of personal identities as comprehensive but that might have been a long time ago, in that case my mistake.

For more info: https://en.wikipedia.org/wiki/Personal_identity_number_(Swed...

megalodon··on The “Cobra Effect” that is disabling paste on password fields
This is what we use here in Sweden as well. The reason it works is that all inhabitants are given a personal identification number upon birth, that consists of our birthday + 4 digits which are loosely based on where we are born and if we are male/female. This number is unique for every person and is used to register to the BankID service (among other things) and ensures that it is connected to a single individual.
megalodon··on Crispr Wins Key Approval to Fight Cancer in Human Trials
Agreed, people seem to be downvoting because they hope he/she's wrong rather than to post a reply explaining their reasoning. I see nothing wrong with the root comment and just upvoted it to give it more attention.
megalodon··on Ask HN: Microsoft Computer Vision API or Google Cloud Vision API?
Hey, I made this [1]. Based on a neural net trained with generated character sets with intentional distortions and/or several font variations.

I would not recommend it for use in production, but maybe you're interested in looking at the code and customizing it to your liking. Could perhaps be combined with OpenCV.

megalodon··on Doctors Without Borders doesn't take money from EU anymore
Sure, here's two articles [1, 2] that describe the situation. Most of the refugees do stay in Turkey (including 1.9M Syrians acc. [1]).

megalodon··on Doctors Without Borders doesn't take money from EU anymore
Thank you for posting this. I am baffled at how some people just ignore reality and post (and believe in?) lies, even here on HN where most of us work with data.

It's amazing that fact checking and critical thinking is so low in this internet age where information is freely available for everyone.

megalodon··on Pills: A simple responsive CSS grid for humans
Wrote this [0] more than a year ago, it generates a tiny CSS grid template using attribute selectors. Should work with any amount of columns. Might be useful for someone here.

megalodon··on Mark Zuckerberg is ‘dictator’ of Facebook ‘nation’: The Pirate Bay founder
> You kind of did, when you signed up.

Problem is many people signed up years ago and I bet they've changed their ToS and privacy policy 100 times since then without people noticing.

Facebook satisfied our needs to connect with our friends when it arrived. Now it's 100% ads. I used to have real discussions with friends, but the comment quality today is basically on par with youtube (if not worse).

What's your point? If you're posting a graph as confusing as this one (4 completely different x scales) at least tell us your interpretation.

Delightful, cringe-entailing humour; this definitely made my day.

megalodon··on Stockholm's 20-year waiting lists for rent-controlled housing
Maybe in the US, but not in Sweden.
megalodon··on The high price of a free college education in Sweden
Yes, I have no idea where they got the "high price" thing from. Here in Sweden you get paid to study at the university (~$350/month for 9 months if studying full time). On top of that you can choose to take a highly beneficial (i.e. better than banks) loan of ~$850/month to cover for expenses like rent, etc. Many choose to take the loan because it's worth it.

megalodon··on Italian court rules food theft 'not a crime' if hungry
> Europeans (DHH for example) constantly brag about what great social safety nets the European countries provide for their people

> Italy has just admitted that it can't take care of its citizens' basic needs.

Maybe you don't, but you are implying that this somehow is a failure of social safety nets.

As someone else in this thread mentioned, the italian justice system is based on civil law, not on precedent (common law) so this ruling doesn't have the repercussions many seem to think. I'm not a lawyer however, so don't quote me on this.
