I find interesting to observe how Microsoft position has changed over the years. They tend to focus now on command line users, and provide tools with open source licenses, it seems they are trying to be more 'Unix-like' these days; still, I don't think they offer any substantial value over mature, powerful and integrated tools, and personally I don't feel attracted to the idea of supporting a company that practices EEE and uses monopoly strategies to retain market share.
Few things make me feel genuinely old like reading about smartphones in K-12 schools.

When I was in high school, there was a part of the student handbook that specifically forbade "wireless devices" used during school hours, and given that only a few kids even had basic cellular phones at the time, enforcement was not only easy, but barely necessary.

A modern classroom where kids are not only texting each other (something I didn't encounter until college) but sending Snaps, posting on Instagram, and playing Clash of Clans is so far outside anything I can imagine from my time in public school as to be from a completely different culture. I thought being a teacher must be hard based on my experiences then – I can hardly fathom what it's like today.
Ask HN: How does consensus work in an enterprise blockchain?
We have seen a lot of focus given to bitcoin's PoW and the electricity usage. This got me thinking how the enterprise offerings like Quorum, Hyperledger work exactly? Are they like a PoS model?

Edit: Based on the inputs, I wanted to add couple more questions.

If the consensus is based on a set of trusted accounts, why are people using the enterprise blockchain stuff still talk about blockchain being "trustless"?

Second, if it is only about a set of shared ledger with multiple trusted parties, what is wrong with an API layer integration? What exactly is the value creation for a full fledged system?

Third, bitcoin blockchain defends against a miner getting hacked by making everyone do PoS. Sure coins will get stolen.

But, if we have a permission-ed server which can add stuff to an enterprise blockchain doesn't it make the whole thing a lot less secure?
My children do not have cell phones (if they want one they can buy it and a data plan themselves - so far that hasn't happened until they are about 18), but teachers assume that every student has a cell phone. The teachers then ask the kids to do things with their cell phones like you are describing. When my kids say they don't have one they are not believed and receive failing grades for the assignment. I've complained to the principal (the school has a policy of no cell phones) but to no avail.
CryptoSteel: Indestructible backup tool for recovery phrases
Perhaps. But my argument concerned the cartoon, which compares 1969 schooling to now. Even if your argument were true, it would mean a flip-flop after only a decade.

Remember, the 1950s and 1960s was the era of "Spock babies", that is, children raised by parents following the advice of Benjamin Spock. Quoting the Wikipedia article about his book:

> By the late 1960s, Spock faced widespread criticism for condoning an overly permissive parenting style. Many commentators blamed Spock for helping to create the counterculture of the 1960s. Critics believed the current youth were rebellious and defiant in part because they had been brought up by Baby and Child Care.

I argue that this is another example of why that cartoon doesn't give a good representation of school in 1969.
Yeah, my attempt at a master's in CS (before deciding the time would be better spent elsewhere) left me feeling largely the same. "Oh, isn't that equation elegant. Oh, wait, actually trying to implement it...what the hell, where is all the other information I need?! That's a gaussian...but where do the parameters for that gaussian come from? What is this variable? WHAT IS THIS VARIABLE?!" etc.

I had a 4.0 departmental in CS from the same school I tried to get a master's in, but yeah, the master's experience was so bad, and working through those issues so time consuming, I just said "Screw it, I can get a better return on this amount of time doing my own things". Even if it's learning the same things, but to an explicit goal rather than just 'understanding' (and an eventual test/assignment that may or may not relate to what I care about), and where I'm not constrained by an academic policy that prevents me from going to others to have them explain exactly what I need to know.
When someone solves a problem with a thing and you're not that impressed, the best response is "cool" or "learning new things is fun" or, like, nothing.

Telling someone they didn't need to do it with that tool is presuming that a) you know why they did it, b) that you are able to judge the suitability for that of that tool for that purpose and under those constraints, and c) that there is no one else who has ever needed to use that exact tool to solve that exact problem under those same constraints.

Which is a form of data leak, and generally against company policies, even though most people still do it.
This feels like Target grasping for straws. They're watching Walmart/Jet.com and asking themselves how to compete. I'd be amazing if they don't fuck this up.
I think you meant from china to the rest of the world. The opposite direction isn’t very difficult to achieve via FDI or a simple bank transfer.
Well, according to the notes there was an entire talk about bias where the example of a Turkish sentence that didn't contain gendered pronouns "X is a nurse, X is a doctor" gets translated to "She is a nurse, he is a doctor" by Google Translate. And apparently that's a problem that needs fixing rather than a reasonable translation, although we all know that Google Translate is trained on the work of human translators, where it presumably learned this (demographically correct) bias from. So I guess they need fixing too.

Seems like NIPS might have a systematic issue with hyper-sensitivity to perceived slights. But it's the intersection of academia and SV companies so is it really a surprise?
While a lot of what you say is true, I think a big factor which isn't overlooked but under accounted for is the worker wage/culture situation. Employee relations get much easier when employees don't have much else choice.

As a counter point, it felt like the engineering talent is still from European countries - note that the plant manager is European, and the machinery they use in the factory is again by a European company. So the upper management that you say moved to finance is still in the industry.

Another reason I think is what some sibling comments of yours have pointed out - lax rules and willingness to co-operate with tech advancement (at the risk of environmental degradation)
What is it, really?
Robert Peston's latest book "WTF" mentions that the distribution of management capability in UK companies is strongly bimodal - we either have great management or awful management.
Well it's a good thing the US won't do this. Considering the SEC just said ICOs are legit, and we now have Bitcoin futures.

But maybe you can go back in time and buy some and you won't be so salty.
Admittedly I'm not the target market, since I use some Windows-only software and my work computer's years-old GPU and is fast enough for the CAD work I do.

I do make incremental upgrades on my personal desktop though (mostly gaming). The last rebuild was triggered by some failed parts, so I ended up doing a new motherboard and processor and switching to DDR4, but I still have the GPU, screen, SSDs, and some other miscellaneous components. If I'd had an out of warranty failure on an iMac Pro motherboard I wouldn't have been able to salvage those. Or perhaps knowing that giving up the computer means losing the screen along with everything else, I'd have just shelled out a couple of thousand dollars on repairs.

I was a pretty early adopter of 4K screens and I'm still using the same one more than three years later.
> Who knows

Anyone who has applied a modicum of thought to the issue. The US already has more per-capita public funding going to healthcare than any other nation, we simply don't get a good return on it because that is perceived as "socialism".

And pursuing a highly conservative fiscal policy (far off the right side of the Overton window) is not going to change that, nor advance the cause of said "socialist" policies. It's flabbergasting that you would suggest that as any kind of a reasonable cause-and-effect.
"plane"

I'm wondering the reverse: what's the advantage to building on UDP, other than passing routers that for some reason are inclined to pass UDP but reject IP protocols they don't know? You said that this was "what UDP was for", and I was hoping for some more detail there on why UDP helps. As you said, it's just 8 bytes and a trivial checksum.
They also don't really care too much about the environment or human rights or property rights. Whatever the government wants done that's beneficial for business in China will generally happen, for better or for worse.
This is supposedly a feature and not a bug of CAPTCHA, at least according to the apocryphal story John Lafferty told me. IIRC, this was at CMU so he must have been referring to the 2003 CAPTCHA claim by von Ahn et al. The idea was primarily to stop spammers, but also secondarily to make them more useful. The argument was that if spammers managed to "break" CAPTCHA, then whatever technology was used to break it would necessarily be a useful (compared to 2003 knowledge) advance in AI, so it was a win-win whether it stopped spammers or just made them do free out-of-band research.
Then kids would just bring two phones. The real phone and a dummy phone.
Well, "commercial" really usually encompasses a whole range of different kinds of contracts depending on the specifics of the load, and there usually are also multiple categories for residential loads, but in the most common case it's simply a matter of the time of day and day of the week that electricity is used.

Commercial use in this general sense is relatively flat throughout the day with little use during night, whereas the residential load profile has peaks in the morning and in the evening with little use late at night and during working hours--it's simply a profile of the average load of a typical household throughout the day vs. the profile of the average load of a "typical business".

Of course, this "typical business" mostly matches offices and retail, industrial users usually have different load profiles, or, for that matter, no real load profile at all, in the sense that they pay based on peak power, not based on energy used, which in effect is an incentive to keep the power profile as flat as possible. Though deviations from that are possible in the form of load shedding, for example, where the utility company can remotely switch off some machinery in the factory to reduce load during peak demand times in exchange for cheaper electricity (this is typically employed with stuff like heating or cooling where it's easy to build your system in such a way that hour long interruptions here and there simply don't matter--your cold storage will stay cool enough even if you stop actively cooling it for an hour, for example).

The overall point is: The utility company doesn't really care what you use the energy for. They don't care whether you produce luxury cars or cheap gadgets. If you are willing to have the lighting in your offices switched off remotely during peak load times, they will happily sell you such a contract for your office building. If you insist on operating your aluminum smelter 24/7, you can have that, though it's going to be expensive. What they care about is the load on their grid and generation facilities, not what you use the energy for.
Pfft, 30k? I'd love to have 30k leads.
I have, like 10 people on my "coming soon" mailing list. And I personally know 5 of them :D

I have no flippin' idea how the other 5 found my landing page. I haven't been running ads or anything. I was going to wait till I actually launched (hopefully in a few weeks).

My thought process was the same. Pay for Adwords, et al., to drive people to a page that basically says "Sorry, we're not ready yet, but sign up for our mailing list, maybe?" Not sure that's a good idea.
it’s unacceptable to ignore users. At least respond and provide a timeline or a reasonable acknowledgement. Sure, your company might have big accounts thst need more attention, but if there are bugs piled up and feature requests left rotting on the shelf - HIRE.

> In maths, papers are devoid of any links, the teaching materials are up to 50 years old and never updated to take advantage of new presentation techniques, authors frequently name-drop some algorithm and then forget to say what parameters they used or how exactly it connects with preceding and following paragraphs.

That there is the crux. If math articles/papers were written in a different medium then you could drill down (right click, view source) from the most abstract level down to the basics. Some kind of tool would need to exist to make this possible.
Exactly what I was thinking. I remember my sophomore year of CS undergrad I emailed IDA's support asking if there was a student license or some equivalent to learn how to use it. Props to them for at least replying, but their answer was a firm no and was disappointing to say the least.
I totally agree, just wanted to clarify that "homeowner" is a generous term in the US intended to make people feel like they own an entire home on the day they close the sale, instead of the reality that they usually own a mortgage balance along with a small chunk of that home.
Loan for Bitcoin purchase?
At what point would a loan make sense to buy Bitcoins and a basket of cheaper crypto-currencies? Is it 15% a year or what? The idea is to get a huge loan, probably backed by my house, and then sell bitcoins to retire a few months from now.
>Or illegal medicine/performance enhancing drugs/...

This is awesome news for the team at Shipt!!

It should be good for Target too. For them it is all about the technology and the entry point with lots of customers. And ultimately about giving them a way to better compete with Amazon and Walmart.
Is there any difference between being able to pick and choose TV channels through a cable provider, and being able to pick and pick and choose services via ISPs?

Seems like a lot of people are against bundling when it comes to cable providers, but it seems to be the same arguments would apply to being against NN.
The “moon” is the value required to have the jaw of your doctor / lawyer neighbor hit the ground when you tell them “I own one bitcoin”.
As an aside, I think companies should take "problem requests" not feature requests. A feature requests implies a solution, and letting your customers be your product designer leads to generally messy and poorly designed products.

So rather than submitting "I'd like the app to do Y", it would be amazing if customers instead submitted "I'm trying to solve problem X and having trouble." Maybe Y is a good solution for X, but maybe Z is too and Z wasn't asked for even though it might be what you need.
I've found that disabling JavaScript actually makes the test easier. I often fail the js version but I rarely fail the no-js one.
It's unfair to say it's a "feature". It was an oversight back in 1989 based on nobody expecting we'd end up where we are today.

Filtering is easy if your just doing it for downstream customers.

But how do Tier 1's filter from each other? Once you go up the tree a few times it gets really hard to build any sort of valid filter list of what you should be getting from provider X or provider Y.

BGPSEC and RPKI are unfortunately not really workable yet, in terms of full-path validation. And obviously the source data to do it is a long way off.
Target is portrayed in the book "Naked Statistics" as having some pretty advanced data collection and modeling techniques -- they could figure out which of their shoppers were pregnant and adjust their weekly ads sent to those particular households depending on that information. This was in fact too good because the pregnant woman ended up being a teenager, and had an angry father calling demanding to speak to a manager.

What any of this means to me is if they have capabilities like that I am sure they made an informed decision based on where they see the market heading and decided this would be a purchase that would increase the bottom line, not grasping for straws as you say.

Yes.

The particular networks announced, and particularly the fact that more specific routes were announced, suggests this is some nefarious incident. Not just an accident that someone announced routes they shouldn't have.
I imagine an airliner flying a pattern this large would take the involvement of more than just the pilot/crew. ATC, airline's planning/staffing group, ground crew (fueling), etc.
The amount of see ice is a regularly fluctuating value, so the notion of "record low sea ice" can have more than one meaning. You seem to interpret it only as "lowest minimum extent", as per the article you cited.

However, the WaPo cites NOAA's 2017 Arctic Report Card, which says this:

> "The lowest winter maximum ice extent in the satellite record (1979-2017) occurred on 7 March 2017. The extent was 14.42 million km2, 8% below the 1981-2010 average. This was the third straight year of a record low winter maximum."

The is a different meaning of "record low sea ice", but it's just as valid.

So I'm asking you, would it address your concern if the WaPo article said something like, "record low winter maximum" instead?

The article mentioned how Brown rented out the Kip's Bay cinema in NY to try to get distribution. That is where I in fact saw it as a small boy with my sister and parents. I never surfed myself but relatives in California did and I always remembered the line about "the dirty Wedge" somewhere near LA. Fond memories... I'll have to see it again.

Partly I'm playing devil's advocate here, as I'm sure there is a good answer... Can you give me an example of a useful, positive contribution that metaphysics and/or philosophy (I confess I don't know what the distinction is between them) have contributed to these topics?

For example, ancient Greek philosophers made many speculations about the nature of atoms, and in some ways their guesses were correct, but I don't think that speculation was especially fruitful. But their advances in geometry and number theory were tremendously productive.

Since the beginning, Google has claimed it was an AI company. They have killed their mantra "do no evil" and now they are putting labs in a country with lower values of ethic. Recently they were selling their robotic activity because it was too frightening. All their actions are consistent with a single aim: build an AI like in singularity or terminator.
Think of it this way, NN is like the post office being forced to charge the same shipping price and provide the same speed for two varying weight packages. A dumbbell vs a letter. The post office is a unique situation because it's crappiness is subsidized by the government and it can continue operating at a loss.
>I understand ISP's are to blame here, but how is it not about Russia, the article specifically states that only certain entities were targeted in a suspicious manner. Seems like nefarious purposes at work here no?

Sure there are. But compare this to an organization getting owned because they didn't patch a known vulnerability. We generally focus on the company that was breached because the power to stop such a breach was in their hands. The same can be said in this situation. ISPs are not proactively taking known measures to minimize the impact of a BGP hijack.

Malicious actors will be malicious...it's what they do. If it's not Russia, it'll be someone else.

The advantage to building on UDP is that it gets through (some) middleboxes; that's what the 4 bytes of port numbers buys you. That, and the fact that UDP is designed to be the TCP/IP escape hatch for things like SCTP that don't want TCP's stream and congestion control semantics.
My list is too long to share, but let me give you a very simple example.

On most chat platforms, the widget displays an "mail" button or something similar that allows the visitor to send the transcript to themselves for reference later on.

Intercom does not have this, and agents don't the ability to quickly send transcripts either. Our team literally has to copy/paste the transcript into a new Zendesk ticket to send it.

Intercom's philosophy dictates that a 'conversation' is an ongoing thing that happens anywhere: in-app if the user is in session or via email once the user's browser session your website has stopped.

Their philosophy ignores the very clear pattern of visitors treating the intercom widget like a "normal" chat widget (which many have come to expect).

The 2 ways to perceive this are:
- Adding this feature adds value for me and I should pay for it
- Adding this feature bring Intercom to parity with customer expectations, and should be included in the price. Not having it is an unnecessary blocker.

I strongly believe in the second one.
I have noticed that some women only tech events tend to go very lightly into technical matters and lean more towards the social justice side of things and I can very easily see just how unappealing such events would be.
