That's one aspect of it. The other aspect of it that because the developer is charging $3,000 - $5,000 they are doing something wrong that the user can do themselves for $50. This sort of mentality creates a toxic market for WP developers. It's fine for people to do it for $50, it's not fine to go around spreading this toxic rhetoric that the developers charging $3000-$5000 are ripping people off. And that's what I read OP's comment as saying and that's what the hostility is directed at.
I watched the whole thing and was a bit disappointed I must say. The TLDR (or W as in watch perhaps) is essentially if we write our programs in a map/reduce (functional) style fashion then the compiler/runtime can sometimes[1] choose between a parallel and a sequential implementation at runtime, depending on what computational resources are available. Seems fairly obvious to me... I would have much preferred the 10 minute version of this talk.

1. Given that the underlying operations are order and grouping independent (associative and commutative) of course.
Certainly, they will have to prove somehow that their app was ultimately removed owning to a competitor's pressure. If they can do that, then the monopolies act and everything will come into the picture. I'm not insinuating that any competitor is doing this to Uber, but that's pretty natural and apparent in this case. Naturally, the store is Apple's business and app publishing is a means of income. No sane business will refuse a business prospect on the grounds of "I don't like you". The only reasoning here is that a competitor is involved. But yeah, proving that in a court of law is a different thing altogether which Uber has to manage.
I've had many tech support calls that amounted to telling people to wait until their earlier clicks had taken effect.

The users clearly initially thought the system was loaded and were shocked to find 30-second delays in their input being registered.

I think it's pretty rude to assume that users are so stupid, just because they don't code, that they can't notice being tricked.
Not everyone is willing to take the time to learn. Some folks just aren't interested in the inner workings of their computer, or maybe they have other things they'd rather spend their time on.

It's like asking everyone to change their car's oil. Sure, it's easy enough to learn to do and will save you money, but some folks would just rather pay somebody else to deal with the problem. Both options are valid.

Don't see this as tricking, it's marketing. EIG offers hosting for next to nothing, and you get what you pay for. If you customer wants to pay for value hosting they can find it by paying more. The other players you are talking about, I don't know how they get customers... it's not easy to get hosting customers, period.
Webrtc itself requires perfect forward secrecy. While you cannot do authentication with it - you need to provide that yourself - you can be certain besides yourself and whomever your signaling server told you is your peer are the only two able to decrypt the packets going between you two.

There are three independent concepts: cost, use value (I usually abbreviate this as "value"), and price, or exchange value (which you are terming value).

There's rather more discussion of this in economic litereature than might be expected, both early (pre-Smith and 19th century) and contemporary.

Trying to make all three of these agree is a bit of a problem. Economic orthodoxy variously tries to do this / pretends they do (and mind, "agree" != "equal").

Content has cost. There's time and effort necessary to create it.

Content has value. It can improve, even drastically change, the lives of those it reaches. That cost may be negative as well -- disinformation or distraction, for exaple.

What content doesn't have much of is exchange value -- it's difficult to draw walls, fences, boxes, or whatever else it is that prevents free access -- around content such that people should pay to get it. And doing that ... has its own sets of problems (generally: under-provisioning of content, particularly to the economically disadvantaged).

Advertising essentially hijacks one content stream (that the audience seeks) with another (that the producer wants distributed). Advertising has value to the author, not audience, and so the author is willing to pay for it to be disseminated. This ... produces numerous perverse incentives. Crappy Web pages among them.

But claiming that no market value (exchange value / price) means no use value, or no cost basis, is simply false. Common, but false.

I used Spine a while back. It's such a lovely tool with a great UI, and compatible with Linux.

It's neither free nor open source though so I don't know if this is very suitable here on HN.

I don't think they are more attentive, but the framework currently curbs the more extreme tendencies of our government(s). Most obvious example is the human rights act (ironically the ECHR is not a body of the EU, despite most media and political spin here implying it is), but also includes the restrictions on GM, safety, and generally in the area of social, labour and market regulation.

Yes, the UK has opted out of several parts, but it can't (yet) opt out of everything. There's precious little accountability within the EU, but it does, at least for now, hold a more centerist position.

Also the EU regional development funds have done more for the UK regions than Westminster ever has.

I registered a domain last week directly from the registrar for $200 a year, which Is a lot for me. I know it is probably at least worth $1000 right now so I could get what I paid out of it at least. The point I am trying to make is that things adopt their real value, domains for an analogy are like real estate.

SF/SV/NYC/LON are very desirable areas and it takes a long time to build out that infrastructure. It is a supply/demand mismatch. Domains were these nebulous things no one understood but if you bought one, it was worth way more than you paid for it. However, JET.com and Genius.com were quite expensive because they are pretty desirable domains, nerdy.com just went for 25K. Supply has gone up so the localpetstores.co.com domains aren'rt really worth anything.

On balance, technology companies-- companies that are leveraging technology well and constantly improve as part of their business, will continue to do well. However, if you define technology as, with a computer then that sector is as descriptive as American or European. Companies in leveraging technology well:

Alphabet

Apple

FB (oculus)

Amazon

Intel

Companies often referred to as "technology companies"

IBM

Twitter

LinkedIn

GE

If you look at the highlevel descriptors, both baskets are fairly comparable, and that is the trap!.

Amazon has a globally unified distribution for digital media, technology applications, physical things, and a marketplace.

Alphabet.

Facebook has 1Billion users and owns much of the messaging. It is how people organize social search. They also are able to marry the phone messaging and image/moments, with the online community of the computer and soon bridge the devide to gaming and a truly addictive world of VR.

Intel is the world leader in building the thing every one of those companies runs on.

etc.

The mismatch between value and perceived value is becoming more evident. So it is, to quote our guy Charlie D, both the best of times and rthe worst of times, some have much infront of them and some have nothing, and the pundits will insist that it is a superlative of this or that, when in reality it is sameness: think hard, be more correct and capitalize on your view of the future.

edit: just to clarify, I plan on using the domain lest anyone think I am a squatter. Although, I do have a tendency to get sidetracked/change gears so I was using that as an analogy above.
A sheet of paper or a blanket would only be a plane segment.
It matters to an extent but I know I am guilty of delaying personal projects just because I can't decide to go with Python or Javascript. Same with frameworks and other tools.
Opal was an operating system research project at the University of Washington in the mid-1990s that had a single, 64-bit address space but also had memory protection between processes. The single address space avoided TLB flushes during context switches, as you point out, and made shared memory RPC much easier (because pointers could be passed between processes because virtual addresses were the safe everywhere).

I recall some discussion about leaking virtual addresses as an optimization to avoid needing to manage or GC large page tables. This was the mid-1990s so a 64-bit address space was more than anyone could possibly need. ;)

Well, they don't like telling anyone they bought out their provider, nor that it's the cause of a previously good service going downhill. The company buys out hosts offering a decent service at (sometimes) higher prices, then turns them into budget providers with low reliability while trying to keep the news on the low.

As for how the other guys get customers... Deals usually. Sometimes literally on web hosting forums, where they talk advantage of the offers section til they inevitably get banned.
Again you are being hostile to your own perception and what you think you are reading.

I did not say the developers were ripping people off. I did not even talk about the value the developers provide. You assumed that I was talking about developers ripping people off which in some way reflects your own inferiority complex about this issue. I read the previous response and neither is that person saying what you are perceiving.
Slightly off topic, but can anyone recommend a webrtc tutorial for data channels or any projects which can be used for player v player over the browser (chrome) . I guess like one player has to be the master and the other players join his/her webrtc connection ?
To be fair, there are real world safety considerations when putting radioactive material into orbit. It's not just a knee jerk reaction, in all likelihood. The risk for Cassini was calculated at 1:1400 (For context, humans have launched something like 8000 man made objects into orbit). That's certainly acceptable when there's no other reasonable way to provide the power that the mission profile requires, but it makes sense that they would go with a more conventional source where possible.
There is an established business model for doing this. I think it was more viable 20 years ago than it is today.

> I really find it hard to believe that security is really wonderfully provided for in a unikernel

I think you've missed the point: The hypervisor provides security. The unikernel does not. Everything in the same unikernel guest is in the same security domain, meaning everything in the same unikernel guest trusts everything else in that unikernel.

The hypervisor is the correct level to provide security because that's all it does. It exists to securely multiplex hardware, to allow multiple unikernel guests to run on the computer at the same time without having to be aware of each other. The hypervisor is, ideally, invisible, in that its only "API" is intercepting hardware access attempts and doing its magic at that point; it provides no abstractions of any kind, so it can be as simple as possible. You can't hit what you can't see, and you can't exploit code which isn't there.

The hypervisor of course uses all of the hardware tricks the CPU provides to provide isolation. Modern virtualization hardware fits the bill just fine here.

It's therefore possible for unikernels to establish and enforce their own security policy, just like how you can run Linux as a guest under Xen. It's just that it shouldn't be necessary in a proper hypervisor/unikernel setup, because everything running in the same guest should trust each other and only need to worry about information coming in from the outside world.
Usenet was arguably more centralised, limited, and vastly smaller in scale that Reddit. (I know whereof I speak: I was there.)

I've been trying to come up with some metrics for the size of "traditional" Usenet -- Big 8 hierarchy, say, early 1990s. Gene "spaff" Spafford thought that 50k - 500k users was probably in the right ballpark.

Note that to gain access you needed to be student or faculty at a research university, or work for one of a handful of tech companies (and almost certainly within their engineering divisions), or for a government agency with access. Very limited independent options existed.

The Usenet Cabal who managed things, such as they were managed, was about the same size as Reddit's technical staff, if that.

And the system proved highly vulnerable not only to spam and crap, but to users not acculturated into the system itself, and behavior protocols. The Eternal September was a thing for a reason.

I agree and that's why I've turned down the freebies the Lyft people are always handing out -- they claim it's for new users and I want to respect that. But then again, I also assumed they'd make a token effort to reject people that already have a registered number with them.

The Qing dynasty, even at the best of times, was far more decentralized than the Communists ever were. Coming in at the disintegration of the Ming, the Manchus absorbed huge swatches of Ming defectors, rebels, and newly conquered territory. By and large, they adopted the pre-existing scholar-official system, and by and large the pre-existing scholar-officials, to run these provinces. The provincial governors were not quite Persian satraps, nor the warlords of the Nationalist era, but they had relatively wide latitude. Moreover, there were parallel bureaucracies, with the Chinese civil administrations, and the Eight Banners standing army cum garrison staffed by Manchus, Mongols and other non-Han. Corruption was rife, and to some extent expected - the level of training and education to pass the gate-keeping imperial exams to enter the scholar class took years and could beggar families or entire communities. Taken to the extreme, you see the case of Heshen, a Manchu official who had embezzled the equivalent of a decade and a half of tax revenue for the entire empire.

Regardless of western meddling, the Qing dynasty was subjected to the deadliest and most destructive war of the 19th century, which nearly toppled the government. And it was largely the third parallel bureaucracy that arose around the two or three most successful leaders against the Taiping that led the westernization push. In the organizations of Zeng Guofan and Li Hongzhang you have the direct precursors of the local warlords who made such a mess of the country for the first fifty years of the 20th century. Already, they operated largely outside the government, building their local fiefdoms.
Thank you for your input! I am actually the product creator's brother but I do know enough about the product and the market to answer some of your concerns!

This device was built for every one in IT, not just network engineers. Not every property is departmental, and many have to resort to outsourcing because they cannot afford a network engineer. This device will vastly reduce cost by reducing the hours spent consulting. It's actually perfect for the not so "Senior" network engineers.

His first prototype was actually the Raspberry PI, but it wasn't enough. He needed a 3400 mah battery, he needed something easier to work with via app and remote, and was sick of having to hunt down commands and run them one at a time.

I dont know about you but I'm totally happy with my A Small Orange shared hosting. Then there's Digital Ocean if you want full control (VPS). The lowest tier is actually cheaper than shared hosting. I'd say, contrary to what you are saying, hosting is easier and there's more option nowadays. You just need to know where to look.
Even there, you have to verify that it doesn't have other side effects beyond sorting (like phoning home your data) and that the mechanisms that enforce any sandboxing meant to stop this also work, etc.

I think you misunderstand the purposes of auditing. They have very strict accounting that they have to follow. There is a degree of "interpretation" on what numbers can be assigned to certain items, but by and large, they just follow a big book of rules. Of course there are certain new business practices that are not reflected fairly and properly by these rules, but that should be the exception, not the norm.

> These things can be reduced to nuisance level by discipline.

Obviously not. We've been doing this for decades and are still making the same mistakes with costly effects. Humans are as much a part of technological systems as the language or platform; continuing to ignore that even educated, disciplined, skilled developers are prone to certain classes of errors -- errors that could be obviated by other components of the system -- is hubris. It is much more feasible to create tools that exclude certain classes of error than to create less fallible developers.

I saw a presentation from a company named parallel machines, they claim x800 faster than Spark performance on pagerank, and you know what, working with GraphX

800 times faster or 800%? 800% (ie, 8 times) is believable, but I'd need a lot of convincing if they are claiming 800 times.

Frank McSherry's work on graph computation is pretty good, and he get's 16 times speed up over Spark[1]. Maybe if they are claiming 800 times less resource usage or something?
