whiteandnerdy··on UK spies using social media data for mass surveillance
Yes, I believe so.

Definition of sensitive data: https://www.legislation.gov.uk/ukpga/1998/29/section/2

Some legal restrictions on processing said data: https://www.legislation.gov.uk/ukpga/1998/29/part/II

However, it's not clear to me to what degree, if any, security agencies are exempt from the Data Protection Act.

But if the system can decrypt itself in your absence it must have access to the decryption keys. So you can't guarantee that the subsequent maintainer of the system won't release the keys after your death. I suppose you could hide the system somewhere (anonymous VPS) but then the encryption isn't actually buying you anything over what the anonymity is getting you.
whiteandnerdy··on Increased acidity found in schizophrenia and bipolar patients’ brains
I'm pleased that the technique worked for you and don't want to denigrate your experience, but looking around it seems that there's very little evidence to support the Buteyko technique, and a fair few red flags: https://sciencebasedmedicine.org/buteyko-breathing-technique...

If it works for you it works for you, but I'd caution readers to be skeptical when trying it out.

whiteandnerdy··on How corporates co-opted mindfulness to make us bear the unbearable (2015)
I totally agree that capitalism can be a powerful force for positive change, and agree that if it makes businesses care about mental health, that's to be celebrated. However I also think it's important to acknowledge that there's no universal law connecting employee wellbeing and profit - right now that might be functionally the case but there's no reason the scales couldn't tip the other way, and so it's dangerous to unquestioningly embrace capitalism as an inherently positive model.

SlateStarCodex's excellent post "Meditations on Moloch", (http://slatestarcodex.com/2014/07/30/meditations-on-moloch/) says it way better than I could so I hope you'll forgive a slightly lengthy quote:

" [M]any of the most important competitions / optimization processes in modern civilization are optimizing for human values. You win at capitalism partly by satisfying customers’ values. You win at democracy partly by satisfying voters’ values.

Suppose there’s a coffee plantation somewhere in Ethiopia that employs Ethiopians to grow coffee beans that get sold to the United States. Maybe it’s locked in a life-and-death struggle with other coffee plantations and wants to throw as many values under the bus as it can to pick up a slight advantage.

But it can’t sacrifice quality of coffee produced too much, or else the Americans won’t buy it. And it can’t sacrifice wages or working conditions too much, or else the Ethiopians won’t work there. And in fact, part of its competition-optimization process is finding the best ways to attract workers and customers that it can, as long as it doesn’t cost them too much money. So this is very promising.

But it’s important to remember exactly how fragile this beneficial equilibrium is.

Suppose the coffee plantations discover a toxic pesticide that will increase their yield but make their customers sick. But their customers don’t know about the pesticide, and the government hasn’t caught up to regulating it yet. Now there’s a tiny uncoupling between “selling to Americans” and “satisfying Americans’ values”, and so of course Americans’ values get thrown under the bus.

Or suppose that there’s a baby boom in Ethiopia and suddenly there are five workers competing for each job. Now the company can afford to lower wages and implement cruel working conditions down to whatever the physical limits are. As soon as there’s an uncoupling between “getting Ethiopians to work here” and “satisfying Ethiopian values”, it doesn’t look too good for Ethiopian values either.

Or suppose someone invents a robot that can pick coffee better and cheaper than a human. The company fires all its laborers and throws them onto the street to die. As soon as the utility of the Ethiopians is no longer necessary for profit, all pressure to maintain it disappears. "

whiteandnerdy··on Americans and Brits will never see the world the same way
Sure, but a lot of people living in London rent their flat and - even if renting unfurnished - have little choice over their white goods. I'm writing this in my London flat with my damp clothes hanging on a rack following a noisy washing run of the machine in my kitchenette :) I'd change product if I could, but it's not an option right now.
whiteandnerdy··on Ask HN: What's your process for learning?
Totally agree on Anki. It's not just for language learning (although it's great for that - I use it for Japanese). I also have a deck for those day-to-day random facts I used to just keep forgetting - family birthdays, proportions for French press coffee, etc.

Gwern calculated the total time spent reviewing the average card is 2 mins across your lifespan (https://www.gwern.net/Spaced%20 repetition) - so anything worth ~3mins investment to learn can go in Anki and you'll never forget it. It's magic.

whiteandnerdy··on In 1957, Five Men Agreed to Stand Under an Exploding Nuclear Bomb (2012)
More likely a grammar error: OP probably meant "I'd volunteer" but conjugated as if "I'd" was "I had" (using the past participle) rather than "I would" (using the bare infinitive). Easy mistake for a non native speaker.
whiteandnerdy··on Gravity: a new programming language and VM written in C
In British English, 'brackets' means parentheses, as opposed to square brackets or curly brackets (also called braces). Maybe OP uses British English.
whiteandnerdy··on Google reveals secret test of AI bot to beat top Go players
It definitely does know how surprising a move is - it generates 'surprisingness' numbers for both itself and its opponent based on how likely it is a human pro would have come up with the move.

I like your idea of maximising the 'alienness' of play though probably not to the exclusion of playing the strongest moves.

whiteandnerdy··on NIST’s new password rules – what you need to know
> I think XKCD is correct here.

> If you choose four random words from a list of 2048 common words, and your attacker knows that's what you're doing, then your entropy is 4 * log_2(2048) = 44 bits. If the attacker didn't know your strategy and tried to brute force letter by letter it would be much higher - around 48log_2(26)=150 bits assuming around eight letters per word - but like you said, we should assume the attacker knows exactly what strategy we're using, so 44 bits is the better number to work with.

> Since that's still more than 28 bits, a 'correct horse battery staple' type password is harder to crack then a short random string of mixed characters, even if the attacker knows exactly what your password generation strategy is.

Typo in the above but can't edit on my phone, the second sum should be 4 \* 8 \* log_2(26). Apologies.

whiteandnerdy··on Ask HN: How do you organise/integrate all the information in your life?
Evernote supports XML and HTML export. I have mine on external drive and in Dropbox. Migrating to a new platform would be horrible, but at least the data's there.
whiteandnerdy··on Show HN: I made a Chrome extension that helps battle impulsive procrastination
I had a similar experience, but I think I've cracked this now. For me the two significant changes were developing a friction-free tracking system, and motivating myself to use it reliably.

For the tracking system, I use Bullet Journalling. You might not need the full power of the bullet journal, but I'd recommend whatever system you do use has the following properties: * You have a 'backlog' to-do list and a 'daily' to-do list. * Every day you copy a subset of the backlog into your daily and cross it off the backlog. Tick things off the daily as you do them. * Daily items should take under an hour, or else you need to break them up into smaller tasks (or alternatively specify "two pomodoros of work on X" as an action) * Whenever you want to track something that doesn't have to be done today, add it to the backlog. * Rewrite your daily list every day. This penalises overcommitting. Moving stuff back to the backlog is allowed, as is dropping stuff. * Rewrite your backlog every month so you can garbage-collect stuff you no longer care about. * Use a hardbound journal to contain all your lists. Bits of paper get lost or messy, and computer tracking is much harder to stick to for some reason. (For me my tracking system has to be distinct from the place I do work, so can't be digital)

Motivation:

The thing that really worked for me here was operant conditioning. Every time you tick off a task, eat a small candy (like an M&M). Every day when you write out your dailies, eat a candy. For everything you want to train yourself to do, eat a candy when you do it. Big tasks get two or three candies.

It's kind of depressing that this is more effective than willpower, but it builds good associations and trains your brain to associate productivity with reward, promoting that dopamine kick. If candy isn't a motivator for you, substitute some other small reward - ideally something you don't indulge in otherwise - but make sure the reward comes immediately after the good behaviour or you won't get the reinforcement.

Hope that's helpful. Productivity tips are very individual, so I don't know whether this will work for you or not.

whiteandnerdy··on Extreme side-effects of antidepressants
Since there's a possibility people will try this, the linked article states that the benefits usually only last until the patient falls asleep. This isn't a practical treatment strategy right now, although it is interesting scientifically. If you have depression I'd urge you to take the advice of a medical professional rather than attempting to self-treat.
whiteandnerdy··on Ask HN: To those who became fluent in a second language, what did you do?
I think the same grammatical construct that's "slangy" when used by a native can sound ignorant or wrong when used by a foreigner, so it's more important for non-native speakers to learn correct grammar.

Examples: * "I done <xyz>" or "I ain't" in English * "Je n'sais pas" in French (I'm told I sound like a moron or a child when I try this)

Thanks for the recommendation - I'm trying out bullet journalling in the workplace as a result. Feels like it's a good system thus far, although I'll have to wait until the honeymoon period dies off to really know.
whiteandnerdy··on Ways to maximize your cognitive potential
To what extent is that connectivity valuable beyond physical exercise? Is there good evidence that this does more than improve coordination and proprioception?

(Obviously coordination and proprioception are valuable, but people who value them likely don't need convincing of the merits of exercise!)

whiteandnerdy··on Federal Court: The Fourth Amendment Does Not Protect Your Home Computer
Yeah, that's crazy. "In Crimes ville, houses are routinely broken into and looted, so the Fourth Amendment doesn't apply in Crimesville"
whiteandnerdy··on Burnout and Mental Health
I'd like to offer a counterpoint to your views on medication. For those who suffer from acute, short-term anxiety over a specific event, for example an exam or an interview, beta blockers such as propranolol can be really helpful - as I understand it they interrupt the fight-or-flight adrenaline response to stop you working yourself into a panic. They were wonderful for me during exams and graduate interviews, and now I barely ever need them. I still suffer from chronic anxiety, but that acute performance anxiety is not a problem for me anymore.

Entering partial passwords prevents MITM. OP was just explaining how partials could be implemented securely by hashing each combination; he wasn't saying hashing prevented MITM.
whiteandnerdy··on Could the Scottish Parliament Stop the UK from Leaving the EU?
I think the position is: technically no, practically almost certainly no, but politically it might be a sensible move for the SNP to strengthen support from Scottish voters.
