Karma is also generally a bad idea because it causes people to comment/submit just to increase it and causes them to say stuff that will give them more karma.

If karma has to be present, it's best if it is a subtle as possible.

Thanks, really great point. BugJail actually started life as internal tool for dynamic analysis, not for debugging. The longer term vision is merging of dynamic and static analysis, so not exactly, or only, "better debugger".
One thing I learned from a recent Everyday Astronaut video is that NASA has a long history of trying to calculate the chances of failure for a vehicle before it has ever flown. They got it wrong with the space shuttle for example. And this method requires a lot of extra factors of safety and expensive parts. An alternate method is to test in flight, and this is what SpaceX does. Boeing uses the other method. So Boeing systems are supposed to be relatively failure free, while some SpaceX systems may at some point be expected to fail. Of course SpaceX is supposed to have their testing done before humans get onboard, so those systems should still be reliable.

But a big difference is Boeing tests on the ground and SpaceX tests in flight.
Going to shoehorn my ideology into this. One thing that became normalized since the 70's was sprawl.
I always think about this too (with people that decide to resort to this sort of activity..and any criminal activity in general).

The difference: you have full control over your destiny, power that you don't have to spend a decade earning..you just take it, and you don't have ask for permission.

There's also a thrill to it. Something you really don't get from a boring desk job..even for the likes of google and Facebook.

It's very similar to those amateur pedo-busting groups on Youtube. Why not just become a detective? Because you then have to go through all kinds of red tape and answer to an asshole boss when things go wrong.

Instead, you can play super hero for views and subscription numbers.
Wait is the point of this article to give Bloomberg some positive press and make him seem technical?
I don't think the fluid is made up of discrete particles as far as pressure goes. The discrete particles are covalent bonded. If they blew up, I think you could put an elbow on a copper pipe, rotate it just the right way with fluid flowing through it and get a voltage. Instead you get cross flow and cavitation.

Perhaps it does happen, and it can't be detected due to matter waves or not being able to accurately trace the path of "something thermal".

Twitter information operation disclosures are for US audiences to appease US congress.

>Earlier this year, we committed to the United States Congress and the public to provide regular updates and information regarding our investigation into foreign interference in political conversations on Twitter.

https://blog.twitter.com/en_us/topics/company/2018/enabling-...

Go through the list of countries / actors Twitter has previously disclosures on, Russia, China, Venezuela, Iran, Spain (Catalan separatist), I think Bangladesh at some point, and these disclosures are functionally US propaganda.

I don't think Twitter is an intentional state actor, but who they report on is constrained by limited resources which means they're incentivized to report on (and censor) US geopolitical rivals even though every serious intelligence agency will run information campaigns.

>Information operations on Twitter: principles, process, and disclosure

Lawful or not, I don't think Twitter has the balls to expose information campaigns contrary to US interest, which is going to be a recipe for more internet balkanization.
What does a theoretical physicist do? [video]
The unevenness of the gravitational field on Earth is for the most part ignorable. It isn't like maneuvers are precise enough that one could account for it in the calculations anyway.

Space is empty enough and engines imprecise enough that for orbital stuff you have enough margins to correctly predict and plan a trajectory ahead of time, and just do correction burns later if necessary.

On the Moon the gravitational field is indeed uneven enough to matter, but exactly one orbiter really cares about it (LRO iirc has a specific orbit where the unevenness mostly cancels out), most simply rely on occasional station keeping burns.
Not quite 40 percent of the market. According to [1], where there are 6.4 billion people and 2.7 billion smartphone users in the top 50 countries, Chinese represent 29% of smartphone owners. In the very long term, assuming use in every country stabilizes at 80% of the population, they're looking at 22%.

I think the more interesting metric to watch is India. With 27% of their population in 2018 owning a smartphone (compared to 55% in China and ~80% in more wealthy Western nations like the US) they're likely to demonstrate meteoric rise in the next few years while Chinese adoption tapers off asymptotically towards the limit. The current 13% representation will rise towards 21%, causing the effective market share of Chinese smartphone owners to drop towards 22%.

This!

This should be emphasised above all other concerns - AWS is absolutely the WORST choice to go for if the company is already struggling with money or not (yet) making any money. It's literally a hole for burning money.

You simply don't go for AWS until you have a superb business plan how to make significantly more money off of your service than Amazon does.
I don't see things in such absolutist terms as that. For everyday language, sure, I'm more than happy to go with the flow. For technical language we need a relatively stable, agreed upon terminology.

Terms that flow and change too freely makes communication very difficult and often leads to people having pointless arguments due to fundamentally misunderstanding what each person is saying. And I do disagree that it's Sisyphean. Raising awareness can and does influence how words are used (especially within a group).
The difference is that on the iPhone, when they see a class of bad actors or a real threat model that they didn’t see before, they can tighten the sandbox much easier than they can on the Mac.

India Now World's 3rd Largest Producer of Scientific Articles: US Report
I read the first half of the article and came away with the impression that dishwashers today are in the same place low flow toilets were in the 90s. They implemented the environmental protection without rethinking the basic functionality and ended up with a markedly inferior product.

If you buy a toilet today it is even better than the old high-flow toilets from the early 20th century in terms of needing only one flush and not being prone to clogs, but there was a time where they were pretty awful.

So the answer may be that the dishwasher industry needs to work harder to more efficiently use that little bit of water and actually get stuff clean.

I will say that I replaced my dishwasher last year and the new one is prone to leaving food residue stuck to the inside of the cups. We even tried pre-rinsing, which we never did in the old one, but it didn't help. We didn't buy some bargain basement model either, it was basically the 2018 version of the same washer we previously used.

'Every once in a while we are sure.' (Quoting someone on the internet)

@:'Reviewing is the center of the mission'
> We moved the platform and every photo to Amazon Web Services (AWS), the industry leader in cloud computing, and modernized its technology along the way. As a result, pages are already 20% faster and photos load 30% more quickly. Platform outages, including Pandas, are way down. Flickr continues to get faster and more stable, and important new features are being built once again.

SmugMug did it primarily to improve stability and performance. They point out that Flickr hosts tens of billions of photos with 100M registered users and hundreds of thousands of paying customers across the globe. I see the need to use AWS (or any cloud provider for that matter) as a necessity to run a paid web service cost effectively at this scale.

You're missing the whole point. Everything fails after a while. Everything. It's the engineer's job to ensure that it fails only after X amount of use, which can be expressed in time of normal usage. There are no time bombs, only the fact that designers picked a small service life.

They hide other instances of bugs so you can't tell if they're de duping them correctly.

They also close them for ridiculous reasons. We've been told stuff like "diskutil isn't meant for root filesystems", etc.

When I was a junior in high school, I worked Christmas Eve and Christmas Day as a lab research assistant.

Why use Python though? Once you are rolling with an ML language wouldn't it make sense to use the C++ interfaces of the machine learning/data science projects that make Python interesting at all?

There are countries where that's required by law. And while that may be on the rather too heavy side of regulation, I have on occasion rage-quit a vendor's site because I couldn't find this most basic information.

I tend to agree. I know you are referring to karma but it also applies to comments. A few times I've found myself doing the same and then chastise myself for it. I think making comment histories private might be a potential solution, some are moving for reddit to do this.

I am honestly torn, as I progress in my career and life, as a sort of contrarian type, I get more and more worried some background check algo is going to find my presence on platforms, troll my history, and find some random comment from 5 years ago that might be controversial and blackball me for it, unbeknownst to me. On the other hand, I hate the idea that we increasingly self censor as we all become more aware of this.

This is why I still think anonymity is important on the internet, and lean towards burning accounts every couple of years on commenting platforms. This is also why I still value what others might call cesspools that are the chans, and of course onion sites et al.

I tend to always think about this Eben Moglen talk (listen from timestamp for 4 or 5 mins) : https://youtu.be/sKOk4Y4inVY?t=427

Interesting to compare to article that came through yesterday about giving up on semantic web, where the whole movement got a sound drubbing in the HN comments.

These are infrastructure problems, they should be treated as such, i.e., maintained by tax dollars.

The failure of the semantic web and the sad state of personal data are primarily failures of the free market to solve these problems, imho.

My photography teachers stressed the importance of "culling" your work and displaying only the best photographs you've taken. I think allowing 1000 free photos is very generous for a fine art photography platform, which is what I want it to be.

I've been taking photography seriously as a hobby for the past three years, and I use Flickr primarily as my portfolio, and right now I have between 100-200 photos on my account. I largely have positive feelings about what SmugMug have been doing with Flickr since their aquisition.

Are there any other interesting articles on good use cases for this kind of centralized data ownership.

Volume.

Let's say their current revenue is R. The 25% promo reduces their revenue to 0.75R, but say they get y% more subscribers. Calculations show that if they can get an increase of more than y > 33.33% in subscriptions, then their promo works.
And they move dramatically less air than those little blowers they put in 1U machines. Sure at lower speeds they are quieter, but when you really need to remove the heat its hard to beat spinning at 4x the RPM, which is noisy.
If you're spending far more money maintaining technical debt-ridden on-premises solutions, then moving to AWS most certainly is the way to go.
> a lot of people seem to really like the object.method() look.

There’s a pretty simple reason for that: autocomplete.

In most halfway decent dev environments, typing “object.” will present you with a list of possible operations on that object. OTOH, if you want to do “method(object)” you need to know the method name (in all current scopes, including globals).

I’m not saying this is the only or even best way to write code, but it’s definitely a factor IMHO.
Today's data concerns Saudi Arabia, somewhat contradicting your theory.
It's a bit of a chicken-and-the-egg problem, but not really. They still needed a solid business plan how to earn money from Flickr before moving to AWS (or any other expensive global cloud) - this kind of looks like they've thought of asking for money AFTER the move.

Discovery of a new source of attention in the brain
[The Navy] gave [Lawrence Waterhouse] an intelligence test. The first question on the math part had to do with boats on a river: Port Smith is 100 miles upstream of Port Jones. The river flows at 5 miles per hour. The boat goes through water at 10 miles per hour. How long does it take to go from Port Smith to Port Jones? How long to come back?

Lawrence immediately saw that it was a trick question. You would have to be some kind of idiot to make the facile assumption that the current would add or subtract 5 miles per hour to or from the speed of the boat. Clearly, 5 miles per hour was nothing more than the average speed. The current would be faster in the middle of the river and slower at the banks. More complicated variations could be expected at bends in the river. Basically it was a question of hydrodynamics, which could be tackled using certain well-known systems of differential equations. Lawrence dove into the problem, rapidly (or so he thought) covering both sides of ten sheets of paper with calculations. Along the way, he realized that one of his assumptions, in combination with the simplified Navier-Stokes equations, had led him into an exploration of a particularly interesting family of partial differential equations. Before he knew it, he had proved a new theorem. If that didn’t prove his intelligence, what would?

Then the time bell rang and the papers were collected. Lawrence managed to hang onto his scratch paper. He took it back to his dorm, typed it up, and mailed it to one of the more approachable math professors at Princeton, who promptly arranged for it to be published in a Parisian mathematics journal.

Lawrence received two free, freshly printed copies of the journal a few months later, in San Diego, California, during mail call on board a large ship called the U.S.S. Nevada. The ship had a band, and the Navy had given Lawrence the job of playing the glockenspiel in it, because their testing procedures had proven that he was not intelligent enough to do anything else.

Absolutely. I am suggesting to do this for all file sharing, so that even for legal bittorrent file sharing, the ISP doesn't even look at you. This also reduces the impact on your bandwidth quota, if you have one. Comcast is 1TB/mo.
As a potential counterpoint to what someone might read from that quote:

I've always run my businesses this way. Aside from positions that really need to have someone during specific hours (mostly positions involving talking to the public), my practice has long been that I pay a salary and don't track hours. As long as deadlines are being met with an acceptable work quality, I don't see why I should care how many, or what, hours people are working.
