As it says,
"If there is one truism in the technology market, it is that premium pricing just doesn’t last."

It definitely has one aspect of a Truism [1] - no-one really looks at the underlying assumptions. The biggest assumption in much of the tech industry is that you're aiming for mass market - the consumer tech brands like Facebook particularly have that assumption - other people follow sometimes without understanding the implications.

If that's your focus, and you have limited differentiation your pricing has to reflect that over time replacements will come in and undercut you. That's the GoPro example he's using, where the parameters of his comparison are the "components of the hardware camera".

What he's missed is that Apple and plenty of others (think every car brand) have shown that brand and real differentiation can prevent new entrants from being able to provide an equivalent that is good enough. The point is that the customer has to believe that product A and product B are comparable - and that the parameters may not just be the bits or atoms.

For example GoPro's brand speaks to "action sports" and being active, they have software and communities that people want to be in. It's perceived as something that 'active people' use and has brand cachet. So the 'replacement' has to capture all that value, not just the hardware costs. Frankly, they've absolutely eaten the lunch of much bigger hardware companies who have far more economies of scale.

The AWS example is even less clear cut. Since Amazon is a retailer we can assume their strategy is mass take-up, and we know that their general pricing strategy is for people to "believe" they are cheapest. But, we also know that Amazon practises differentiation, we've seen that with Kindle and Amazon Prime. If you look at the AWS services you can see they are aiming to provide a highly differentiated service aside from "simple" IaaS. We also know that as a retailer Amazon uses extremely sophisticated pricing strategies. At this point I would think that Amazon is continuing to drive down the cost of basic IaaS due to economies of scale which makes it very difficult for competitors to get started, while keeping the cost up of 'value-added' services which provide differentiated service and make the whole service a lot more sticky. They will probably do Amazon Prime like things with their whole portfolio over time.

There are plenty of businesses where the strategy of being cheapest is right, but it's not the only approach.

I don't think XML was all that widely used, and the implementation looked more "looks interesting, let's develop something and people will use that".

With JSONB it's more like "people are already using JSON data type (text + validations) a lot, and want something better, and we do have hstore, and we're working on hstore 2.0, so let's use the ideas for json". And that's how JSONB was born.

My estimate is there are already more people using JSONB than XML (talking about the PostgreSQL data types), so the momentum is very different.
As long as it's just a better product, there will always be those willing to pay a little more. Even if the product is part for part the same as a competitor's, better customer service might still warrant a premium price. Not having to go through the hassle of dealing with a horrible RMA process for example, is worth the extra money to me.

The nice thing about customer service, is that its monetary value is very hard to quantify, making objective comparison difficult. So there's always room to charge extra.

To be fair, Excel internals must be too brittle to allow for more extreme redesigns; they've been piling up layer upon layer of technological changes for three decades, and they need to keep it working without crashing too much.

I don't know Apple's Calcs, but Microsoft has built the PowerPivot extension that largely works as a modern, parallel version of Excel embedded within the same window. If you need to work on Excel with large datasets and/or complex relations, it may pay off to learn this extension.

I never considered that point. Do AWS prices fall slower than Moore's law, and do they fall slower than the prices of the underlying equipment?

I have managed a goodly number of AWS implementations and considerations ("should we do it or not?"). AWS was cheaper in most cases not because of bare metal vs AWS, but because of the sheer efficiency of scale, and not having to hire staff and expertise to manage all of the infrastructure.

Hmm... you just inspired a new post. Thanks, noelwelsh!

MVCC means "Multiversion Concurrency Control" and yes, that's pretty much exactly how it works (creating copies of the rows, so that different snapshots see different rows).

In practice it's more complicated of course. A nice intro to MVCC is available here: http://momjian.us/main/writings/pgsql/mvcc.pdf (and in the Bruce's other talks http://momjian.us/main/presentations/internals.html).

Or maybe you mean something else by Multi-value-Concurrency. In that case please elaborate.

The Csmith paper notes two types of errors found in CompCert: front-end errors and a misunderstanding of PPC semantics.

The former type of bug was apparently due to a part of the compiler that wasn't verified at the time. According to the Csmith paper, " This bug and five others like it were in CompCert’s unverified front-end code. Partly in response to these bug reports, the main CompCert developer expanded the verified portion of CompCert to include C’s integer promotions and other tricky implicit casts."

Additionally, the CompCert team produced a validated parser which they discussed in their ESOP 2012 paper, "Validating LR(1) Parsers"

The second type of bug (misunderstanding the semantics of the target architecture) is, as far as I know, impossible to avoid. Any verification project can end up with a true proof of the wrong theorem!
REM0TE from Europe for Win UI C++ dev?
I think you're totally right. There's a product manager somewhere in AWS whose using the comparison "total cost and productivity of managing own infrastructure" vs AWS. That means cost of people building/managing servers, but also goes much higher up the stack into the other services they provide from backup, content distribution, etc. In fact, Amazon is commoditising simple IaaS because that comparison would be AWS vs "Buying my own server and plugging it at the datacentre" which would be a lot less compelling. They want to drive the first comparison, while stopping others getting started in the second one.
That question clearly fit the canned reason for closing. It was a homework debugging question on a tight deadline.
Canadian startup launches classified site price guide
I would say the argument doesn't have anything to do with premium pricing and everything to do with lock-in.

In the case of AWS, prices are cheap. But once you've built your software to use all of the proprietary AWS services, it's not economically feasible to switch to another cloud provider. You're locked in.

This works similarly for Apple. You do pay more for the product, but it's not trivial to switch to a cheaper Android device after plugging into the Apple ecosystem.

GoPro clearly can't continue to win technologically (what comes after 4k?), and they don't have an ecosystem to lock you in.
I've been working for the last two months in a personal project to build a 8-bit microcomputer based on AVR MCUs. Because these MUCs use a Harvard architecture I implemented a 6502 VM to run programs from external SRAM.

But I digress; the relevant bits for this story are that I'm using CC65, a compiler for the 6502, so I can write programs in C for my toy computer.

It's impressive the amount of stuff CC65 does in its runtime just to implement C. Sure the 6502 is a beautiful processor (I loved implementing the VM!), but it is also very limited.

Just an example: C65 implements its own stack in regular memory space because the actual stack of the 6502 is limited to 256 bytes!

Every time you pass a pointer as a parameter in a function call the compiler loads the 16 bit address in A and X and pushes it into its own stack, where the the destination will access to it as needed.

Look at the pushax implementation here: https://github.com/cc65/cc65/blob/master/libsrc/runtime/push...

All that just to "push value in a/x onto the stack". Amazing :)

there are couple misconceptions here

99% of startups don't solve hard problems (it seem hard to them because they are inexperienced and excited but in all reality not so challenging ) , that doesn't mean they don't have good business idea but technical aspect is mostly easy , challenges usually come with scale which happens later

financial upside for 0.2% equity end 100Mil exit is --> 200000 at best and that is not much so where is that upside for somebody taking 80K instead 140k over 4 years ? Not to mention that probability of that happening is low to start with

in small startup it would be essential to have extremely qualified people , excitement should be secondary

I do what I do because I love it but that doesn't mean I have to do that for free or cheap so correlation between asking for fair price and not being excited (passionate) about what you do is mostly not there

I worked in couple of startups (last one had exit 500Mil) but I was paid market rate and that is mostly a reason why they succeeded (got high quality people knowing exactly what they are doing)
Strange that they are working in secrecy. I would guess something like[1] would be better.

I've read a couple of good books recently (Sapiens: A Brief History of Humankind by Yuval Noah Harari being my favourite) which make a convincing case for human evolution having mostly finished sometime around 100,000 - 50,000BCE when we homo sapiens started migrating out of Africa. It's pretty amazing to think that there were human beings walking around back then who were at least as mentally developed, if not more, than we are today.
But writing Wile's proof in a machine-checkable language wouldn't have been a problem in itself?

There is no "universal" machine-checkable language which can be used for any proof. I don't know if Wiles' proof could have been written in Coq, for example. Let's say it can't, and that no existing machine-checkable language can be used for this purpose. In such a case, you would have to develop a new proof language, and make sure the proof checker itself is correct.

I guess that at some point we are hitting the theoretical limits imposed by the halting problem and Gödel's incompleteness theorems?

It's not my field so I'm just asking questions here. Don't hesitate to lecture me :-)

> What I'm really interested in is whether it's possible to have a cryptocurrency that doesn't rely on e.g. blockchain technology.

Yes, it is possible. MaidSafe is building the solution as we speak, and does not get anywhere near the attention it deserves. Because there is such a general lack of understanding of its underpinnings, it is usually lumped together with other blockchain technologies or altcoins. There is no blockchain, there are no transaction fees, and transactions are irreversible almost immediately (no confirmation time). There is no wasteful mining.

I wrote a pretty comprehensive article[0] on how it works from a technological standpoint if anyone is interested. Perhaps someone will find it useful.

Page seems unclear about what the actual intent is. First it simply says "demanding that they finally come clean" i.e. inform you if your communications have been intercepted, but then you have to agree "...to request my records to be deleted."

What if I want to know the former, just out of curiosity, but I'm not that bothered about demanding my records be deleted, depending on what was intercepted?

Improving the nation's overall STEM skills is more important than just trying to focus on programming. Programming is not the hard part -- planning, deducing, structuring, hypothesizing, analyzing and so on.

Programming is just one way to apply those skills.
If they're very well known and everyone can understand them and implement them perfectly, we wouldn't need formal verification in the first place.

I don't doubt that formal verification significantly reduces the chances of bugs, but it's not a panacea, or we have computers that read our minds. You still need to verify that the proof is proving the right thing, although you can be sure that it's internally consistent.

"Investment bankers, being paid as they are for action, constantly urge acquirers to pay 20% to 50% premiums over market price for publicly-held businesses. The bankers tell the buyer that the premium is justified for “control value” and for the wonderful things that are going to happen once the acquirer’s CEO takes charge. (What acquisition-hungry manager will challenge that assertion?)

A few years later, bankers – bearing straight faces – again appear and just as earnestly urge spinning off the earlier acquisition in order to “unlock shareholder value.” Spin-offs, of course, strip the owning company of its purported “control value” without any compensating payment. The bankers explain that the spun-off company will flourish because its management will be more entrepreneurial, having been freed from the smothering bureaucracy of the parent company. (So much for that talented CEO we met earlier.)

If the divesting company later wishes to reacquire the spun-off operation, it presumably would again be urged by its bankers to pay a hefty “control” premium for the privilege. (Mental “flexibility” of this sort by the banking fraternity has prompted the saying that fees too often lead to transactions rather than transactions leading to fees.)"
IPv6 is (getting more) relevant in parts of the world, because (duh) we're running out of IPv4 addresses. All the backbones and most data centers are already fully IPv6 capable, don't know about cloud providers though.
If I rent a bare metal or VPS i can expect full IPv6 connectivity, at least with all the big vendors here in Germany.

We have ISPs here (Unitymedia, one of the largest German cable companies) that have run out of IPv4 and started handing out IPv6-only contrancts to all new customers. Those customers have to access IPv4 resources using DS-Lite /CGN (carrier grade NAT), which is a horrible workaround with a lot of issues.
Funny enugh, the same ISPs won't give IPv6 to existing customers because every change will probably lead to increased support costs and make the customer unprofitable.

There was a great talk by a Cisco guy at last year's FOSDEM explaining what to expect with IPv6 and why CGN really, really sucks. Video: https://archive.fosdem.org/2014/schedule/event/no_more_ipv4/

So yes, everyone who serves stuff on the internet should care because you already have or will soon have customers that only have native IPv6 and are best served reliably over IPv6.

Your quotation has distorted the original a bit. (Well, of course the original is in French, but Lewis Galantière’s translation into English is also lovely.) It’s from chapter 3 of the book Wind, Sand & Stars (in French, Terre des hommes). Here’s the full text of that chapter, which I highly recommend to everyone: https://gist.github.com/anonymous/cd950f8ac6d58349e9e6

And here’s the paragraph surrounding the quotation in question (if I remember correctly the paragraphs are arranged a bit differently in the French original, but anyway...):

It is as if there were a natural law which ordained that to achieve this end, to refine the curve of a piece of furniture, or a ship’s keel, or the fuselage of an airplane, until gradually it partakes of the elementary purity of the curve of a human breast or shoulder, there must be the experimentation of several generations of craftsmen. In anything at all, perfection is finally attained not when there is no longer anything to add, but when there is no longer anything to take away, when a body has been stripped down to its nakedness.
