Latent factor models have a really interesting history. They were developed heavily by psychologists (among others) over the past century, for use in testing and assessment. Nowadays, it's pretty interesting to see people in ML sometimes resurrect an old factor modeling approach, and make it scale, apply it to something radically different, etc..
I can't read the pay-walled article, but based off my own habits I do wonder what has really changed. I don't have cable, but I pay Netflix, Amazon, HBO, Sling, MLB, and the NFL anywhere from $8-$25 per month. At this point, that isn't much different than the old model. I'm not saving any real money and I still pay for plenty of content that I have absolutely zero interest in ever watching. The only difference is that instead of paying a single middleman for my TV, I moved slightly upstream and pay a handful of providers.

How can you differentiate between different "types of noise"? If the traffic is cryptographically sound, the signal is indistinguishable from the noise. If the messages from multiple people have a guessable seed, in such a way that you can identify what is noise, it just means that the system is not cryptographically sound.

I don't think that getting rid of 'Adtech' altogether is the answer. It's still a valuable source of revenue for many companies.

The point of the article was that the way 'Adtech' is currently used is broken. Ads shouldn't be a frustration or interruption to the native experiences where they are hosted.

I like the concept of RAM (Reward Activated Marketing) mentioned in the article, it takes into account UX, and good UX will always win.
No it doesn't, because most everyday users don't give a toss about security. It has to be something that is pushed as a best-practice by those who know better, not something that is demanded by an everyday user who doesn't. The invisible hand won't do shit here.

I can think of a couple of issues which might underlie the economic issues of South Africa and Russia: namely thee end of one party rule in both states.

There really was no 'collapse' of the South African economy - it's been growing rapidly since the end of apartheid. Just some chaos during the transition. Crime expanded quite a lot and it had nothing to do with 'neoliberalism'.

And both nations would have had to go a heavy and chaotic transitionary period.

To imply that it was part of some cabal of Western Imperialist 'Doctrine' is completely false.

There were a lot of resources up for grabs - and a lot of money ploughing in.

True! That info is what the paper you are trying to write is all about. You take these TBs of data, and effectively compress it into a single graph of maybe 5kB, the thing you really care about.

However, you still have to keep all the data around for possible re-analysis depending on the terms of the paper you submitted to, for up to 10 years or more in some cases, along with all the equipment and maybe some frozen fish samples in LN2 down in the basement. Now, not all labs are so well funded, and sometimes accidents happen and grad students are not always so informed about these rules, but you should be keeping it all ready for re-testing for some number of years. You simply cannot get rid of it all for the sake of science.

If you really want to help out bio-peepz, then helping them program is a great way to do so. Spaghetti does not even come close to describing their 'code'. If anyone really wanted to reproduce the experiment, then they would have to wade into the fetid swamp of 'code' that produced it. Most bio people cannot even begin to tell you how to code or what it even means. They can PCR and Western Blot better than Jesus himself, but code? No way. It is a real hindrance to the sciences, actually. The helping hand that code was meant to be has become a ball-n-chain that drags peoples minds away from them and 'lets the computer do it' for them.

The worst part is that HTTPS is there and works, all they need to do is add the HSTS header and they would instantly improve the security of every single visitor for free.

I generally hate when people point out things like "if you really cared about your users like you said you do, you'd implement [unrelated thing]", but in this case it's an extremely small change that would improve the privacy for every single one of their visitors.
Resource extraction companies (oil, mining, etc..) usually are required to post security for reclamation. However, large companies are permitted to not post cash or bond, but on their word (credit). Which works while commodity prices are high. But when prices crash, so do the companies and society (the tax payer) is left holding the bag for cleanup.

Wouldn't bandwidth/transfer costs basically nullify the computing gains? I know someone who used to be in genomics and cloud-anything was priced-out due to transfer costs.
Yeah, it shouldn't be confusing! We extended early backer pricing for the whole Kickstarter, so the Personal / SMB license would have been $40.

Only difference is who can use the license. Student license is for students only. But I'm recommending students just get the full Personal / SMB license since it's more flexible in the end and a better price.

(Non-profits should ABSOLUTELY get the Student / NP license as it's good for any organization size and just $20).
Text editing is basically 90% of command-line interfaces, and Emacs has its own Unix-like shell with Unix-like utilities (that work the same on every platform, even Windows), terminal emulator, file manager, a bunch of email clients (I stopped using any for a while, although I plan to try using mu4e over the holidays), add-ons for any kind of programming language and version control and build system, stuff like calendars and spreadsheets, a file system emulator that lets you transparently work with remote files over a bunch of different protocols (no need to try to set up NFS or whatever on Windows), and all this works the same on any OS and over a terminal connection. It is a great text UI for most computing tasks.

> How can you differentiate between different "types of noise"? If the traffic is cryptographically sound, the signal is indistinguishable from the noise.

Message length, relative timing, average bandwidth, ports used, source/destination addresses, activity punch-card.

I'd assume that this kind of traffic is identifiable to within near perfect certainty, which would also make it easy to block.

The situation is a bit similar to early crypto-analysis: it's totally easy to devise a cipher that makes text look random to the eye, but is still easily cracked using statistics (eg. frequency method). Just because traffic patterns look all complex and random doesn't mean that there is a meaningful amount of entropy in it (but you need a lot of entropy to hide all the metadata - who with whom and when). Just because bandwidth or packet frequency looks independent of user activity it doesn't mean that it actually is.
Thanks for clarifying.

Off-topic, but related to undefined in Haskell, I love holes in Idris as a way to represent incomplete programs. I'd love if it somebody could take them one step further and have it so that if a hole is evaluated at runtime, a prompt came up and said "Well this is the input, what do you think the output should be?". You type it in, the program keeps going and a unit test is generated and put away somewhere for you to make sure that later when you implement it, you can help verify that you're doing it right.
> How do you remember which commit to diff against?

Ideally your commit message would indicate this. If you're always consistent in the language you use to describe similar changes, you can just search through your git log to find it.

> How do you easily pick out the relevant parts of that diff once many changes have occurred - months or even years later?

You can use `git show` to just look at that one commit where you deleted the code

Personally this is the main reason why I have never considered using AWS for my small projects, but maybe this is an intentional choice by Amazon, to keep away "hobbyists" and only go after companies where an extra $1k in AWS bills this month is just a blip on the radar...

See http://www.eia.gov/energyexplained/index.cfm?page=oil_use

Total petroleum products: 19.531 (million barrels/day)

Of which, deleting fuels,

Asphalt and road oil 0.343
Petrochemical feedstocks 0.331
Lubricant 0.138
Miscellaneous products and others 0.089
Waxes 0.006

which sum to 0.907

If the oil industry existed solely for non-fuel uses, it would be extremely tiny, and probably entirely domestic. It would not be large enough to fund any new deep or complex drilling, and nor would it be large enough to fund even the fixed costs of existing wells.
Still not fixed. I'all reply here when it is. Might be a few days because of reinvent stuff.

Eh, look at the journals for the reasoning there. Many editors and reviewers don't have the time to untangle multi-variate effects and make certain the math was right. Maybe that was because they can't do it themselves, but usually if it is that complicated and interconnected and you come out with a 'clear' picture, odds are that it was an error. I'm NOT saying that is in fact true at all. However, most editors get so very many submissions every day that they take the easy to understand papers with clear results and pathways over the harder to understand ones that are more likely to have errors in them as they are more complicated. This feeds backwards into the grad schools and then only simple pathways and mechanisms are encouraged and nurtured, while complex ones are left alone in the publish-or-perish environment. And yes, this is BS, but that is how grants get funded.
At the expense of cleaner, safer ones no less.
Even better, electrolyze water and run the hydrogen through a standard Haber-Bosch ammonia plant. It's a little more complicated but much more energy efficient. It's been done on an industrial scale in the past with electricity from hydropower.

Pro-tip: if you are having trouble starting or keeping with this, get some 3x5 cards and write / practice from them every day. 5 mins, whatever.

I realize that keeping them on your phone, etc, will let you have them anywhere, but it will let you have them at the expense of using them on a device with lots of distractions. Plus, the physicality of writing and looking over cards is sort of theureputic (for me at least).
$30/month on phone is not hard if you don't use an overlarge amount of data (or if you never talk on the phone and use <5GB from TMobile's old 5GB for $30 but with only 100 minutes deal).

idk about internet, "good bandwidth" in my area is >>$50. Probably depends on where you are and what your definition of good bandwidth is.
" like groundwater pollution, earthquakes, above ground pipelines, etc"

Groundwater pollution and earthquakes are rare, and the latter are minor and have negligible impact. It's no more problematic than most other extraction industries.

'Above ground pipelines' are completely benign entities with almost zero environmental impact. Leaks are rare enough, and most of them are very minor and easy to clean up. Oil is an organic product, found commonly in nature, and small amounts of Oil spilled have no real impact. Unlike the big tanker spills, which can be devastating.

The highway you drive your car on has considerably more environmental footprint than any 'above ground pipeline'.

> What I do is I have the "basic" TV + internet package, as that's actually cheaper bundled than getting internet by itself.

I've heard this before, and on the surface seems like it's probably skewing a lot of the numbers (making the number of cable TV subscribers artificially higher than it otherwise would be).

At the same time, you, like many others, do have it hooked up to your TV, and you watch it at least occasionally. Despite the bundle being cheaper, you still are by all metrics a legit cable TV subscriber.

The big question is if it wasn't cheaper, would you still have cable TV? If it was $1 more to get TV vs just internet, would you do it, and at what point does it become too expensive?
Reiterating the questions posed at the end,

To what extent should personal ethics play in deciding where a (software) engineer should work? What if the engineer has no other choices for a job, and needs to (make rent/pay the bills/eat food)?

It is true that it'd be pretty easy to circumvent the tracking, by placing paper over the webcam, running the browser in a virtual machine, spoofing data to the browser, and so on. However these are infeasible for most non-technical people, so I don't think it's a real solution. Freedom shouldn't be only for those with extremely technical knowledge.

There was a dramatic downturn in the South African economy after 1994, not a collapse like Russia but our industry took a huge knock, the Rand weaken dramatically, there was vast disinvestment and job losses. Yes there was growth, but like all neoliberal regimes it has gone to the wealthiest 1%. Today South Africa is significantly worse in most social indicators than it was in 1994.

Thanks for a well thought out response that adds value to the discussion. Some of the other responses irked me because of how little thought was given to these harsh realities and I responded in kind. Don't be put off if you read those responses.

I just watched the video. I would love to agree but I can't. Mind you, I'm speaking as someone who grew up in the inner-city. This doesn't mean that people there were unhappy, disconnected - something the video seems to think is the root cause. In fact, it was usually the opposite. Parties, strong family bonds, lots of strong personal connections, outgoing - and still... drug-addicts. Fact is, I was one of the few that was introverted and disconnected (geek).

The Vietnam sample given in the video doesn't speak to how often the users were taking drugs, how often they went cold turkey, how difficult it was to attain drugs. They played a section of a lonely and scared soldier but did not discuss situations where a group of soldiers, in a welcoming environment, shared the experience.

What a person needs to do to get drugs (not having the resources) and how it changes them over time isn't dealt with in the video at all. They slowly become accustomed to the new changes (theft, prostitution, assault) and work from there.

The very same people I have known in life who have been drug-addicts have only changed their lives when they hit rock-bottom as a result of tough love or jail time. Some never manage it despite all the effort in the world.

Nothing else changed in their lives - not their personal connections, not their work situation, nothing. This is at odds with the message of the video. In fact, love and compassion along with strong friendly bonds led to enabling in every case that I witnessed.

I don't want to sound like some kind of expert. The topic, which I never should have engaged in, brings back many bad memories. Mothers leaving & destroying their families, two cases where a baby was thrown out a window (once during a party), a son killing their mother, a heterosexual male teen engaged in homosexual sex for money, overdose ending in death, young suburban girls living on the streets, the wife of a friend leaving her husband for weeks at a time to prostitute for money. Sigh... And more...

I am a firm believer that even the nicest person will willingly engage in the worst kinds of crimes under the right conditions. We can all be broken. We should always be on guard to protect ourselves from situations that can break us. Drugs are one of these devices.

> I don't believe we should mandate what people can and cannot do with their bodies

I agree with this 100%. Suicide, daredevil acts, tats, all-night gaming sessions... whatever. So long as it doesn't hurt anyone else: My right to swing my fist ends where your nose begins.

This has never been the case with drug addicts, in my experience. Every drug addict effects those around them in negative and often dangerous ways.
Yes, IMO.

"they tend to spill a lot which is worse than burning it."

Both parts are not correct.

First, they spill very little in the grand scheme of things.

Second, an 'oil spill' unless it's quite large, is not a hugely damaging thing for the environment. Oil is a plentiful, organic material, found everywhere in nature. It's just not concentrated enough in most places to be extracted.

The soil in northern Alberta (an area the size of Florida) is literally oozing with hydrocarbons - same for Venezuela and many other places. Nobody considers those parts of the world 'toxic' - they are otherwise normal places.
