"yet its people were immensely proud of advances in Korea/Afghanistan/Vietnam/Egypt and whatever other warzone the USSR was involved at that time"

Afghanistan was in late 1970-s, I mean come on. Egypt before that but pretty far from ruins period. One can probably only claim it about Korean War.
Just in time. That XPath example is really useful for me.

I didn't finished the article yet, but I have one question. Is there ability in Scrapy to append new data after initial scrapping?

For example site at the moment of scrapping:

Article 1
Article 2

Then we run scrapy again after some time and site will look like this:

Article 1
Article 2
Article 3
Article 4

Can it just append article 3 and 4 to file/db table and stop scraping?
I suppose you could say Postgres did end up as an object-relational database still, composite UDT’s, array’s and domains are all features that match the original vision.
Ok, sure. Why does having a public ledger imply anybody can control your data? Can I take your Bitcoin? You're being outright stupid tbh.
It's kinda weird that people here focus on how there are power cuts for existing users, how this govt wants to give away free things etc.

All this move guarantees is that the people who never officially had a power connection get one. This might well be a marketing scheme, but as long as they deliver, we are good. It's kinda ridiculous that a Prime Minister i 2017 have to make a plan to get everyone power. How difficult was this for the previous govt?
Even beside economic and pricing issues that can eat away at percents, a perfectly managed system could have surplus 20 hours of the day and a deficit 4 hours a day. You need significant excess power to avoid blackouts in a world without very cheap batteries.

Um, no. Under Article III section 1 of the U.S. Constitution, federal judges are appointed for life, and their salary cannot be reduced [0]. In general, judges are prohibited from accepting compensation from parties before them, and indeed are quite restricted in what outside compensation they can accept for anything [1].

A million times this! I live in Chicago and am an avid biker (been doored by a cab, right of passage i guess?) I am one of the few who stops at stop signs and slows down or stops at cross walks to watch for pedestrians. I attend my local alderman's meetings to push for more protected bike lanes which we are now getting, but my fellow bikers are making us all look bad wrt following the rules of the road. I can't tell you how many times I've almost gotten hit crossing a cross walk by a biker flying down the street without looking or stopping for pedestrians. We are now at the point where bikes are truly getting to share the road, but we are forgetting that we don't just share with cars, but with pedestrians as well. That fact seems to elude most bikers and they are operating like they have total impunity when riding. I'd love to see cops out ticketing bikers for blowing through cross walks with pedestrians present, I'd love to see big fines for running red lights; lord knows our city needs the revenue.
OP seems to be saying to throw a ton of money at search. Microsoft spent billions in losses over the past decade. Profitable now, but market share isn't too strong. And a lot of the market share gains are from Yahoo anyway.

So I agree. I don't see how Yahoo double or triple spending what Bing spent helping. Especially if they start out in 2017. On the other hand, if they work with Bing and have some sort of search engine Joint Venture with money and smarts poured in, maybe they can put a dent into search. I doubt Apple who care about profits so much would be down for such an endeavor.

> “I sold at $5,000 or $4,980,” he said.

I doubt it. If you follow the Bitcoin price you'll know that a lot of indices reported the price hit over $5,000 but that was because the Chinese exchanges were trading at a premium (up to $5,150 on OKCoin) which dragged it up.

It didn't actually hit $5,000 on Coinbase, Bitfinex and Bitstamp - and when it did trade at high $4900s it was for low volume for a very short period of time

The reason why the price delta between the USD and CNY exchanges is high is because of how difficult it is to trade between the two (also because of restrictions on CNY)

So he's either trading on Chinese exchanges and figured that out, or ..
So what you're saying is: we shouldn't react to this news, because Russia didn't actually influence our election... and we know Russia didn't actually influence our election, because we didn't react?

That's... impressively circular.

First off, we don't know that he/she hasn't used any of the money. We only know that this "person" hasn't used any of the coin we know to belong to them. We don't know how much other coin they have mined and subsequently spent. I don't think you at point to those first blocks as evidence it's not ponzi in nature. I don't think it is a ponzi scheme or at least I hope it's not. But I do think that it looks an awful lot like one.

An exception in India, a small state called Kerala which has achieved 100% electrification recently. This do not mean there are power outages and voltage problems. This is among many other socio economic achievements which makes it stands out when compared to other states in India. It has achieved these feats through a model of development which is now called "Kerala model".

It's not just ""vetting"", which is deeply suspect in the first place ("let's go through this person's facebook and apply our arbitary prejudices to it"), but it can also be retroactive.

It's entirely concievable that someone could be in the US for years, have a family, make a political facebook post (maybe "take a knee") and then be deported.
> People living in fear.

In the former Eastblock people weren't living in fear either, as long as they did not think of sticking their heads up too far above the field in terms of political activism and such. If you did then you were pretty sure to be targeted.

China today is still very repressive when it comes to political freedom.

https://freedomhouse.org/report/freedom-world/2017/china

And as long as they are 'one party rule' I think that it is both strong and for political reasons. Keep in mind that all of politics is ultimately rooted in economy so it is pretty easy to get lost in the mix.

> Population control through forced abortions and murders everywhere (it turned out to be not true).

https://en.wikipedia.org/wiki/One-child_policy

It very much turned out to be true, and you can add a very large number of forced sterilizations to that list.

> Evil communist leaders.

That's an opinion, I'm not going to argue with opinions.

> Shit-quality manufacturing (that's the fault of western companies; China manufactures to the specs you give and pay for, it's western companies that decide to cheap out on products).

This is false. China can make quality products but there is also a culture of substitution where quality samples are replaced with lower grade manufacture at later points in a contract to deliver. This has bitten many Western companies that turned to China for their manufacturing and which has caused a lot of companies to bring their quality control to China, just before shipping to save on the amount of stuff shipped that simply did not work or did not work as advertised. This QA issue has been very well documented and can definitely not be laid at the door of the Western companies placing their orders in good faith.

> Those are all things I've been led to believe through media reports.

Media mostly reports, it mostly does not make stuff up. And most of those media reports are backed by at least my personal experience over the years where I will be more than happy to note that this stuff isn't a constant but that there are trends with some stuff improving and other things worsening. If you know your stuff it is very well possible to manufacture quality goods in China.

> The point being, whatever happened there 40 or 60 years ago, currently China is not that much different from the US

That is hilarious in so many ways. China is extremely different from the US along almost any axis that you care to name. Other than that of course the Chinese are people, just like Americans and Europeans but that's about it.

> and unlike the latter, it's only getting better.

This may very well be true, but then again, that's a function of where they were only a few decades ago. It's hard to remain at the top of something if there are other parties that wish to ascend, in dutch we have a proverb that reads 'standing still is going backwards' (I'm not sure how well that translates), but it fairly accurately sums up the sentiment.
There have been a ton of start-ups that I've talked to / been a part of who used MongoDb thinking their company is going to exponentially explode in MAU and they think they'll save themselves the scaling troubles by using NoSQL. What ends up happening is the codebase gets too gnarly when they try to start doing complex analysis. SQL is appropriate for like 95% of companies. A lot of these places I'm referencing end up porting their codebase to Postgres, mysql or oracle.
US greatly lacks that separation in between the executive branch and the judiciary for simple reasons:

1. Top tiers judges are nominated by the executive branch, there are no other way up there.

2. For a high tier judge in US, a promotion is effectively a political promotion

3. US law, as I know, has no provisions for disbarring a judge for bad judgement even if it is plainly going against the what is written in the code. Only gross miscarriage of justice (graft, proven act of conspiracy, and 3 or 4 violations of court procedures) allows for impeachment by congress

All of that makes appointing politically aligned judges too attractive for executive branch officials who want to extend their powers through them

I would love to bike, but the major issue is that every single person I know who's biked for more than 1 year has gotten into some type of accident (around 10 people), whether car, car door, or poorly maintained road. These are all 30s and work-at-the-office types so maybe they're not the most coordinated, but they are also not doing stupid shit.
Isn't that just mostly using major search engine indexes? I know DDG some of its own indexing, but how much do they really do on their own? I don't see the benefit of getting DDG for them when they'll have to deal with the major search engines providing most of the data anyway.
I love OmniFocus, but have always been bothered by a lack of web interface or Android client. (I use Focus GTD as an unofficial client on Android, and it's less than perfect at best.) I've been looking for something like this. Going to try it out and hopefully provide some insight.
They're all jumping ship now. I hope congress, or the FBI, hold some of these people responsible for the mess they've created, and take Equifax to the woodshed.

I live in the East Village and am convinced that cyclists in New York City have no regard for human life. The NYPD seems to be cracking down on their lawless behavior, but I think a push away from cycling and towards ride-sharing (a la Via) is the solution for our transit issue.

With our broken subway system and high volume of cabs, ubers, etc; it is clear that New York is a driving city - but not a parking city.
I think the opposite, and that CQL is the only reason people still adopt Cassandra today. Remember Thrift, which started by using terms like columns and rows for completely different concepts and went downhill from there? I felt it was a very interesting choice to have CQL only capable of expressing queries that Cassandra could perform quickly. It forced people to adjust their data models immediately, rather than defer the problem until the performance issues got too deep to ignore. Its a different mindset to relational databases, for different sorts of problems. If only they had used the same sort of restraint on other features attempting to make Cassandra do things it is unsuitable for, such as 'transactions' and counters, which are just an embarrassment of problems.
You are accusing an international corporation of maliciously software crippling millions of devices worth billions of dollars. With that in mind, this is easily testable and has been researched and debunked in the past. If apple was caught doing this there would a multi-billion dollar class-action suit.

What’s more likely is each new phone is significantly faster and more efficient than previous iterations. Thus, new software designed for “current” devices will run dramatically slower on a device even two years old. Fun fact, the most intense gain being made in processor tech is by apple and their SoC tech. Each new A series chip blows away competition to the continued amazement of most.
> there's no need for machine learning, neural networks or etc.

There is if:
1. You want an energy-efficient distributed representation of the function.
2. You want to use the function as an initial guess and then learn online afterwards.
Yes. My door to door commute by bike takes about 30 minutes but by public transport takes about 60 minutes. In fact, being able to commute by bike is the reason I moved out to a nicer, larger place than I would have considered if constrained to public transport only.

This is not enough. We need a reform to legislation to make these companies liable both for data breaches and for false information. Too often the CRAs are used effectively as extortion mechanisms whereby your credit rating his held hostage to extract money you don't owe for collection agencies.
Postgres (as an example) has no upper limit for database size, and the upper limit for a single table was 64TB a while ago, perhaps higher now. And you can buy stock hardware with 6 TB RAM and 76TB SSD e.g. from Dell.

If you max out that single server, you could easily hire one database engineer to care about horizontal scaling.
Is there a definition of "social media"?

Does it include forums? Closed forums? Anything with a chat capability? A website that uses a third party chat widget and another third party address book?

What is social media according to the US government?
"or the FBI, hold some of these people responsible"

Hopefully, this then will create a different culture in other companies. Things did change after Enron (though SOX is such a pain).
As someone who's written a lot of DOM code, i've tried dropping jquery (and do) but selectively. You cannot drop it completely without great pain.

It's true that the DOM interface has stabilised and is now mostly consistent cross browser, however the API is massively unwieldy in places, from excessively long method names to irritating asymmetric potholes.

TLDR; Jquery is not needed for cross browser now, it's needed to make using the DOM API not so ridiculously verbose and long winded. You need to use jQuery today because: you want your DOM code to be 1/5th the size, more legible, more debug-able.

I still use native methods where possible where there is little difference, especially when performance is a concern.
"Demonetization exercise was a total and epic disaster and it shocked the economy without fulfilling it's motive of "war on black money" as 99% of the invalid notes were returned to the RBI."

That was exactly the point. The fact that 99% of notes were returned indicates that demonetization was a success.

The whole idea was to stop large cash transactions from occurring in secrecy where they cannot be taxed.

Any economic problems resulting from demonetization are short-term. In the long run, moving to electronic transactions will be of great benefit to India.
To be fair, I have seen plenty of cases where doing a join in code is actually better for performance reasons. And I am apparently not alone since Django’s prefetch_related() does exactly this. Reading a two million rows from a database is faster than one trillion.

Having said that, I’d your database doesn’t support joins, you have no option and are stuck having to do it in application code and that sucks.
Hmmm let me get this straight: 143,000,000+ people have to pay Equifax $3-20+ to get their credit frozen, and you get to just walk away and retire with oodles of money from your illicit stock selling and severance packages? There is no justice sometimes.

That's around ~430,000,000 USD for Equifax alone [edit: if] 143M people got their credit frozen at $3 per freeze. (Obviously back of napkin math, and not everybody pays the same or even freezes their credit)
It's very high risk, but I can imagine the bull case becoming a reality some day:

Approximately $10.5 trillion US dollars exists today. Some sources claim that the total value of all fiat currencies in circulation (or storage) in the world amounts to $75 trillion.

The total market cap of ALL cryptocurrencies today is less than $150 billion. This means that if cryptocurrencies replace traditional currencies, then you can expect a 500x increase in the total value of all cryptocurrencies.
But it's not going to all go into Bitcoin; it's going to be spread across millions (if not billions) of unique cryptocurrencies and new ones are going to rise and fall all the time (like apps on the app store, except fairer).
There will be exchanges to convert between any cryptocurrency immaginable; they will all communicate with exchanges via a standard protocol. So any new currency which implements the protocol will be immediately tradeable on any exchange.

Different groups of people will affiliate themselves with different cryptocurrencies and this will allow the combined net worth of different groups of people to float freely on the market based on how much the rest of society values their labor/output. To get rich, it will just be a matter of associating with the the right groups of people at the right time (by buying their currency). It will be the ultimate free market.

That's what we have done (algo trading). Our research backend uses pandas, but we ended up taking about a month removing it from prod code. It does surprising things with memory usage, and the functionality we needed was more or less wrappers around numpy anyway. Most of our performance critical code is in cython as well. For this trading application, speed obviously isn't the biggest concern, so python+numpy is fine. It is C++/Java everywhere else though.

Reading one of the only papers in his self-published "journal" that isn't concerned with showing that immigrants have lower IQs or more criminality than native white populations probably isn't the best way to establish whether he's a white supremacist or not, though it might be evidence for the claim that he's more contrarian crank than obsessive nationalist.

One can of course draw rather more obvious negative inferences about the quality of his research from everything from the paper's laughable description of the sampling methodology to its entire premise that correlation between responses semi-arbitrarily assumed to represent intelligence demonstrates validity of that set of responses as a measure of cognitive ability.
The flip side of that is that Apple continues to provide software updates to super-old hardware. How many Android phones get updates for 4 years?

However, I agree that if you do install that final OS update, it tends to make performance terrible. I regretted installing iOS 10 on my iPhone 5; and the unfortunate thing was that there was no way to downgrade.
