Once an HR drone has explicitly told me that my side projects had zero value for the application, even though they matched what was being searched for.
I can not imagine it is that good of a deal as I get calls about people wanting to help me with my foreign exchange on a monthly basis for many years now.

There is not topic that I get more cold calls on than this. This suggests to me, this means it must be fairly profitable for those companies offering it, and that profit likely would come out of my pockets, but I haven't done the analysis.

That said, I know my bank has pretty shitty exchange rates:

Metro Trains Melbourne – Legacy Train Control System Stabilization
The amount of energy required to lift an object to 50,000 feet altitude under mach 1 is insignificant compared to the amount of energy required to achieve orbit. You're basically talking about making a rocket, but saving a very small amount of fuel by starting a little higher in the atmosphere. Then you double the delta-v required by having a dead stop in orbit. That much delta-v would require a very large multi-stage rocket indeed, which defeats the object of your exercise.
First, let's define value vs price. Price is how much the "valuation" is, exit price, maybe even cash flow.

Value is how much wealth it creates.

PG wrote a lot on this:
http://paulgraham.com/wealth.html

Basically build something really valuable, then figure out how to make money from it. Different things have different value.

For example, Google is something extremely valuable, but they charge a tiny amount compared to the value they provide. Twitter and Facebook create a lot of wealth too. Even though they seem like toys, they're powerful and influential media sources.

What about Wikipedia?

Peter Thiel brought up this idea of X% of Y wealth. Something can create 5 billion dollars of wealth, but doesn't monetize well. Examples are Wikipedia and a lot of scientific research jobs.

Something very valuable can be bought for cheap. Something can be overpriced and become a "unicorn" without creating that much wealth too.

How much money people have also defines its price. If two $50B companies want to buy out a company, it can be sold very expensive. But if the only acquirers are $10M companies, it's going to sell at a few millions max, even if it's the same thing.

Acquiring is often used as a way to hire. If something like Facebook dumps $1B on building a messenger, they may not succeed. And then something like WhatsApp comes up and threatens their billion dollar baby. So it makes sense to acquire early to cut out the threat, even at a premium.

There's also localization to deal with. Let's say you want an e-commerce company in Indonesia, a huge and lucrative market. Logistics is very crude, laws are complicated, and there's a lot of corruption and bribery to be paid where an American wouldn't even know where to expect. Starting one is extremely risky and difficult. Nobody wants to hire 300 people in a month.

This is where it makes sense to acquire at a premium.

The reverse goes for talent. Generally companies in Indonesia could not find the same level of talent, because the brilliant people have moved to Sydney, Silicon Valley, and so on. If tech was a key component in their dominance, it's easier to just buy an Australian company than deal with recruiting locals or starting a company in a tech hub.

Ego of the acquirer also plays a big factor. Some people just have a lot of money and are in a saturated market where they can't reinvest it in themselves. Usually telcos. They want to dump it into something that makes money, like logistics or e-commerce or SaaS. They usually overestimate their ability and underestimate the difficulty of the task, so they won't pay very much to acquire.

Finally, the price of a company goes way up if it can monopolize an industry. This is why Facebook and Twitter is worth do damn much. Nobody will go to another microblogging site if they don't have to. Interestingly, the Chinese have their own versions, which are just as rich.

In general,
1. Do important things
2. Do difficult things
3. Do things rich people can't do
4. Network effects

A story from a young programmer
By its own admission, it's more about creating competent technicians by presenting them with the foundations created by engineers (who in turn are informed and prepared by the science, although that is neither mentioned nor explained, but rather is almost dismissed by treating standard science curricula as "top-down" and "at a superficial level").

The introduction uses the analogy of a shop class:

the prospective student is starting out trying to work on a Forumla One engine without ever knowing how a two stroke motor operates[...] Nobody will expect them to be a Formula One engineer, but they are well on their way

This appears to be yet another example of terminology inflation in computing, where technicians are called engineers or even scientists with little regard to what those terms actually mean in the wider technical world.

Yes. Apologies. I will make an addition to my comment. I was only addressing sub-orbital flight, not orbital flight. The initial article was about the old NY-to-Tokyo in 2 hours thing we've been reading about for ages.

You cannot make orbit, but you should be able to go a long ways ballistically.

Add: A great way to learn about the energies involved is to create your own simulator in your programming language of choice. The ballstic/orbital math isn't that hard, and you don't run into a huge number of problems just modeling how to get to orbit.

I did this many years ago, and concluded that for non-biological items, mass drivers win hands-down. Unless the magic of field propulsion finally happens, taking your own fuel along with you sucks.

I suspect most Rpi users just download some IMG-file from the internet, load it up on a SD-card, and run that as is.

Great job! I had had the good fortune to talk to Ravi dai (of OLE Nepal) and pick his brains a couple of times. And then we had a few things planned with OLE (and later OLPC) guys, but they sort of petered out. And since then, everyone has been in haste to get out of there, so I don't have many contacts in Nepal anymore. If you know someone still interested in rural-tech stuff, let me know: I know a few people (myself included) willing to put in a little bit of money each as business investments. : )
Fortunately, there's an easy workaround for the ever-increasing land rents, which should work even in places like the SF Bay Area: you can just have a group of people pool their resources to pay for a given plot of land, usually in the form of an "apartment building". Unfortunately, those are illegal in almost all of the Bay Area, and in SF itself, even in the few places where you can build a new one, the process takes forever and costs a lot of money. As a result, housing becomes a rare and collectible good, and people have to either crowd into the existing units, pay a lot of money, or have punishingly long commutes.

You can still reach some of your audience freely. You can argue that Facebook is rent-seeking, but consider the problem that it solves: if every fanpage could reach all their audience for free, every user's timeline would turn into a product catalog.

Just go and count how many things you've liked so far. I have 821 "items" liked, most of them fanpages. If every one of them would be able to reach me with all their posts, I'd quit Facebook on the spot. The users are not there for the fanpages. That's why Facebook won't let companies hit everyone. Now whether or not they should allow people to pay for wider reach, that's questionable, but then again - it at least makes people prioritize. If you have a limited marketing budget, you will tend to pay for and thus prioritize more important communication.

You might want to add webp support to Firefox for Android then, and just spoof star.google.com/whatever TLD they support and star.youtube.com, too.

Or should I just shut up and let the people weep until we go to some other topic?

This.
I think WebGL is suitable to mention. Whilst it is strictly speaking GLSL, with a little WebGL wrapper to execture and pass parameters, it's the WebGL part which sets the users expectation that it is a live demo and functional in-browser. I don't think you'd have that same inference from GLSL alone.
I live in the UK and have had a Mondo card for about a month and a half. I've been very pleased with them so far, and there is clearly a big opportunity for them to bring some innovation to traditional banking.

> HN on firefox is bad. Comments doesn't have any hierarchy.

On desktop, at least, you can fix this by making your browser window wider (just resize the window: you'll find a threshold past which the hierarchy appears or disappears).

That doesn't help much for mobile, where you can't really resize windows.
It seems to me your client is stiffing not just you but their own (paying?) end users too. Why is the end user paying your client if you are the one providing the service and support? Perhaps you can look at some way of making the end user your client.
I was trying it in Opera. A chromium based browser that always had WebGL as far as I know. Even the previous version had optional WebGL (so user agent blocking would not made sense either). So unless this code was written 5 years ago, it's useless. And even if it was, it's obviously badly written and useless as well.

For any bond with reasonable trading volumes the ratings are irrelevant, because you can just look at the spread over the relevant benchmark - UST, Bund, JBG, Gilt etc. The market tells you how risky it is; think back to 2010 and the way Greek-German govie spread ballooned out. The problem is with illiquid bonds. Some credits don't trade frequently, so a last trade price may be days or weeks old.

> First of all, it doesn't matter. Facebook is not your competitor, so you're not harming yourself.

You start by saying that Facebook is not a competitor, but in taking over part of your core business--- keeping track of potential customers--- it could be seen as that.

> Secondly, Facebook is an immensely popular communications platform. Even if for some reason you dislike them because they're privately owned, it doesn't change the fact that that's where people are. If you want to reach people, you want to be where they are.

Facebook's objective is total control of all communication and it will stubbornly refuse to allow the migration of its data off platform. It will fight tooth and nail to prevent any other competing alternatives for social communication (such as open ones like email) from being seen as viable. Frankly, that's a business risk for us all, because it moves control of communication into the hands of a third party. By coming down hard in support of them you are doing an important part of their marketing dirty work.

The net benefit for consumers is unclear. They may like it now but we are still in the honeymoon phase of this monopolistic process.

> I mean, I get it. There are some exchanges we both agree that we want to have. You can't make a reliable newsletter via Facebook, nor I would like to get my account info through Messenger. But please move your ad communications to Facebook, where they will be unobtrusive for us and properly curtailed by the platform.

Your support for them is so superlative that I have to ask: Do you have a stake in Facebook?
In your hypothetical, the initial flight is doing almost none of the real work and you might as well just launch that booster from the ground. Look at the rocket equation. You have to achieve a given delta-v to get into orbit. That drives the required mass ratio of the rocket. Getting up to 500 mph or whatever a B-52 can do basically has negligible impact on the required delta-v, so the require rocket size is no smaller.

SCRAMJETS are interesting because they can get up to a significant fraction of the required delta-v while in air-breathing mode. They can do that because unlike a traditional jet engine, they don't have to slow air down to subsonic speeds for combustion. That's what drives the maximum speed of traditional jet engines.

Edit: saw your other response. Delta-v is still an issue for suborbital trajectories. Hitting 100 km altitude requires a speed of about 3,200 mph. If you've got a subsonic air breathing stage, you're still not getting much benefit. The big benefit of SCRAMJETS for suborbital flight is that they can hit the required speeds in air-breathing mode the whole way. No need to carry around heavy oxidizer.

I persisted and find that although the results are different, they are often just different. Once I became used to DDG it's started to seem like Google is the broken one.

As long as someone understands the platform you can do this. I've seen way too much iOS code written by smart people new to iOS with no clue how to structure and ship a successful mobile app. This is likely true for most platforms. A smart developer can learn in time but usually you don't get that time so it's better if at least someone has done whatever it is before. I am sure I could master Android in time but if I started building an app on day 1 it would likely be terrible.

I've been left wondering how the Mondo/Mastercard rate actually works: yes they pick some rate based on X, Y and Z, but how does this interact with the market described in the post?

I suspect not very much at all, at least for major currencies, as Mastercard has people buying $ for £ in the UK, and £ for $ in the US, so they only need to go onto the market for the imbalance, allowing an "incredibly good" rate, when they're not exchanging much on the open market at all...

Cynical answer: because companies want to see that you'll write code for free, so you'll never ask for a raise or overtime.

The less cynical answer is because working on some open source thing at least exposes your willingness to contribute, look at other peoples' code etc. It can be hard to tell how much someone actually contributed just by looking at a CV.
So, in a nutshell, these guys are saying that (a) it's too easy to get a misleading cert and (b) they make it easier to get a certain kind of cert. That's going to be a hard sell. They need to make a case that non-EV certs are worthless not only in terms of security but to consumers - i.e. that you, the certificate buyer, will lose business. Then they need to explain why EV certs are better, and lastly how that superiority can be preserved even on a shorter acquisition timeline. They do none of that. The article is not only too pitch-y for HN, but it's also a poor pitch.
Very much speculative bubbles being popped. One of the most interesting things was what Dr. Michael Burry (one of the main characters in Michael Lewis' The Big Short) noted in a recent interview:

I strongly agree with this author: Spanking and Child Development: We Know Enough Now To Stop Hitting Our Children[1]

> Spanking remains a common, if controversial, childrearing practice in the United States. In this article, I pair mounting research indicating that spanking is both ineffective and harmful with professional and human rights opinions disavowing the practice. I conclude that spanking is a form of violence against children that should no longer be a part of American childrearing.

My stance is consistent with the recommendations of the American Psychological Association [2] and the American Academy of Pediatrics [3].

The issue is can we have a discussion about it without unfriending each other on Facebook building protective bubbles.
