Wilson writes that the investors setting the high 'headline' valuation are really "buying a bond plus an option". That is, the preferred-payback amount, plus an upside, rather than what a layperson might think of as X% of a $Y billion company.

I wonder, then: could or should these big investments be structured as {bond + options} rather than {preferred-stock + liquidation-preference}... precisely to avoid the misperceptions of a giant 'valuation'?
>I nearly got the light blue and green confused, and I have normal color vision. //

Define normal.

I have some difficulty differentiating blues and greens sometimes but I found those shades to be quite distinct even on a low quality screen.

Perhaps your colour differentiation is worse than you think? It could be down to monitor settings though, for example.

There's an Ishihara test here - http://colorvisiontesting.com/ishihara.htm FWIW but I'd imagine you'd need to see an optician to do it correctly.

Special Case Laws of Exponents for Powers of Two
Fair point. To clarify, I meant build quality more so than power of internals (though the internals are nice too!).
I don't hate XML, I just think it tends to be misused.

I (still) think XML is fine for configuration files and things like markup of UI/UX components (See: Flex, WPF, Android layouts, etc). In this context, where you may be modelling the relationship between many parents with many children nested fairly deeply, I find XML much more readable and easy to edit and reason about than JSON.

Where XML makes little sense is as an over-the-wire network protocol format or in any context where its "human readable"/"human editable" properties aren't as important. In those contexts, I think JSON is far better suited though neither is completely ideal.
Glad you noticed :). It took couple of months of our designer and iOS developer time.
Work: I have plans to develop myself as a freelancer. I've just read ￼￼￼￼Brennan Dunn's 'Double your freelancing rate' and I'm really motived. I have to build up my presence online and create a business network to start getting referals (just 2 clients so far).
Also I have some stuff I'm working on and ideas to develop next year:

- A replacement for OSX's Console App

- Website Blog platform

- Some weird stuff I may think...

Ideally I would like to get at least 3 new clients this year and ship any of my ideas.

Life-style: I'm planning running the Barcelona marathon and hopefully New York's one too. I'm using asics training web-tool and started running in October, so I very confident that I will made it!
Why the downvoting? I was just pointing that the OC makes a non argument. If one wants to prevent ambiguity of the text, and one thinks that the evenness of is not clear for the intended audience, one adds a appositive parenthesis reinforcing that fact.
I might view it in reverse: having been in a start-up is an advantage/practice for stable marriage.
Yes,

But I would claim that by being designed for many jobs in a sloppy way, XML became a terrible tool for all jobs.

Json is a good replacement for XML in some of the application for which some folks foolishly targeted XML (I worked on a server back in the day that really did process five times the data 'cause of our use of XML for interchange - as was the new standard at the time, remember "XML everywhere!"?).

Html is a good tool for web documents (who would have thought?) but you're right, XML fills in for a lot of other document uses - XML is so far the best generalization that splits the difference between a word document and an HTML file. But I suspect the celebrate if someone could put forward a better such generalization because even in the realms where XML is the best tool available, it is a bad tool.

Perhaps if more people admitted the awful attribute/value ambiguity problem that the article very intelligently calls-out, the use of XML would be less painful. If we called it "Inconsistently Structured Data Intermingling Format" ISDIF, the young developers would have some idea what they were getting into.
When I first came across Fourier transforms I just thought of it as a bunch of sine and cosine waves destructively/constructively interfering. Could be because we derived FT in class starting by matching sine/cosines to intersect various points.

If you ignore the anarcho-capitalism fanatics, you can see bitcoin has its uses. It is great for international trade without having to use Paypal. And there are no chargebacks.

The big problem with Bitcoin is that it is really slow to verify a transaction so it is not going to replace current solutions in the next decade. But it definitely has a niche.

However the price of bitcoins barely risen by $1 so I doubt Iranians have bought more than $10,000 worth of bitcoins.

No, you are simply associating with people who compliment your own interests (and presumably vice-versa). Not everyone can be friends with everyone. Trying to make relationship "work" when the individuals are fundamentally incompatible is the source of much unhappiness.

This should hopefully change as WebRTC gets more fleshed out support. It's something I aim to try and tackle in my own webcam library (that was posted here a short while ago), but yeah. Finding an efficient way to even send a single frame is a bit awkward, and there's more than one way to do it.
On the other hand, comments were explicitly excluded from JSON by Crockford (with the thinking — probably correct — that they'd be abused to embed such things as parsing directives or other out-of-band content)
You don't deserve scorn for failing, it's ok. You might be suffering from some kind of anxiety, and you're being too hard on yourself for sure.

One piece of advice that might help you: when you're trying to measure your progress, instead of looking at the people who are ahead of you all the time, sometimes look at the people who are behind you. The people who you've exceeded, who you have done better than. It's an important part of motivation that's often overlooked. (This and a bunch of other really excellent advice I got from Seneca in Letters from a Stoic.)

Also, don't give up. You've only truly failed when you quit learning or give up.
Goals change over time. Maybe one person thinks their best exit is via the publicity of running the operation, while another person thinks their best exit is via selling the company, while another thinks the best exit is to extract profits from the company.

And companies don't found themselves to be easy to break up, for the same reasons people don't set up prenups on marriages.
What's the point of pgbouncer2 (postgresql)
i didn't have the need to use pgbouncer yet, so i never really figured out its cons. (nearly) no prepared statements is a big down, but if you design your db with functions (i.e. you only do "select get_my_data();"), it fortunately doesn't matter.
If I never quit and I never win, what do you want from me?
And all of those potential confusion, controversy, lawsuits, fights, and wasted time come out of the fact that a lot of people don't think zero is even, which is the whole point they were trying to make.

when meta-YC matters more than YC, shark has been jumped
I've found in the past, for on-premise consulting, that I'm being paid to consult/develop, but being used as a psychiatric sounding board. I don't give advice I'm not qualified for, but being there under the guise of development and just listening seems to be a worthy use of my time (and their money) for some clients.

I can get more work done remote, but there's a greater personal connection locally. It's interesting what a consulting gig can turn into.

The book I recommend for this is "From One to Zero". http://www.amazon.com/From-One-Zero-Georges-Ifrah/dp/0670373.... The reviews on Amazon do not make me reconsider that. "From One to Zero" comes over as both having more content per page and more pages.
For those of you entranced by the top-line numbers here, you have to also remember that the cost of living in San Francisco (especially with regards to housing) is also extremely high. For example, according to Wolfram|Alpha a $95,000 salary in Seattle is worth $137,000 in San Francisco [1].

I must admit, while nice, I never understand the upvotes for such icon collections? I'd expect that if you started using them, you'd inevitably quickly find that you miss some crucial icons, which you would then commission from the original creator. So these collections are merely ads?

I wish the artists all the best, just don't understand the HN appeal. (This is also not a "not HN material" post, it's a question, as these collections appear to be a recurring thing).
For me, it's knowing that all the "other stuff" I have to do is done. Inbox clear, no meetings about to happen, etc.
Without further clarifications it is at best ambiguous in English: Sometimes the "or" is meant to allow both options, sometimes not.

When mathematicians talk in English they usually (by convention) mean the "or" of first order logic (i.e., inclusive or). Since they happen to be the ones talking about even/odd numbers and they are a group of people that do require a language specific enough to have to specify whether the "or" is inclusive or exclusive, it seems like a good idea that such a statement should be taken in this framework.
I'm not keen on XML for configuration files, it's just too full of junk to read quickly.

An interesting idea, and even more so if true. However, this web reference only gives a whiff of a hint at where to find the real research. That real research is behind the infamous "Nature" paywall. The "Nature" people never let anything out of their paywall, so in general, we'll never see this paper.

Don't even bother reading the link, the title is as much info as you're going to get out of it.
JSON not having comments is a benefit when used for it's primary purpose: information exchange. JSON is not a great format for configuration files or static documents even though it's increasingly used for it.
"really slow to verify a transaction"

10 minutes to get into the block chain + 50 minutes (5 additional rounds) to shift the probabilities of a fraudulent transaction (e.g. double-spending) down near 0.

This may or may not be too slow depending on the transaction.
How data, statistics and numbers will make you do the wrong thing
It looks like you meant "'an even number, which includes zero' for that effect", but on first reading, it appeared to me (and perhaps your downvoters), that you meant "'an even number', which includes zero for that effect", which would be a significantly less productive comment.
This looks like an interesting idea but I get the feeling there isn't a business behind it yet and they are just seeing if people are interested at this stage.

In my opinion this would be great a service if they provided online backups as well similar to Dropbox.

I can't seem to find any information about what countries they will be service either.
the main arguments are about syntax. there's no mention of namespaces and schema are dismissed because the author didn't use them. no mention of tools for automated processing.

this is not a very good article, in all honesty. he doesn't like the syntax, but doesn't seem to consider that different technologies can be suited to different problems, or that he simply hasn't experienced the kind of uses where xml works well.

> Having said that, it sounds like if I just followed your advice above I may get the same results as I get from listening to the tracks getsomeheadspace provides.

Perhaps. Some like to listen to light jazz or classical music while meditating, but I like white noise, wind blowing, and passing traffic best. I think it's very important that you don't meditate in front of your computer because it puts your brain in a high-activity, instant-gratification mode, which is the opposite of what you want. Just the fan on my computer in enough to make me think about checking reddit or my email or whatever. Even something as simple as moving to a room you don't normally stay in can be enough to wind down your mind and become more relaxed.

> Meditation was a bit of mystery to me before watching them.

Meditation IS a mystery. If anyone ever tells you "IT IS THIS!", they are wrong. There are countless methods devised by people from all over the world and they all work. Some think you must lay down and listen to music. Others think you must sit cross-legged. Some even believe you must to it standing up! Some think you must count to ten, others say do it backwards. There are those who say think "nothing", and those who say think "anything". Some say "concentrate", some say "relax".

But the best advice I ever got: "Just sit."

Show HN: MuSE - Markup using Symbolic Expressions. What do you think?
I'm not sure I understand this idea at all. To me, it sounds a bit like gasoline companies asking from Walmart or Costco to pay them because a lot of people drive to Walmart and Costco using their gasoline. That may be true, but they pay exactly for that! Moreover, the only reason why people buy gasoline is to drive to places, so where the idea that somebody owes them extra for that comes from?

In the same way, internet access is a commodity and the only reason I pay for it is that I need to get to Google or Netflix or such. Where the idea that Google or Netflix get "free ride" comes from? I pay for my access, Google and Netflix pay for their connectivity. If the connectivity is not enough, customers would complain and depending on where the problem is, end up paying for better local access (if they know it's slow for them but fine for the neighbor next door that uses different provider) or have their provider (i.e. Netflix) upgrade their connectivity by telling them to improve delivery or they stop paying/visiting/clicking on ads. This all should work as it works now, where the idea of a "free ride" and additional payments due comes from?

XML can do the same trick with indirect objects as COS, using ID and IDREF type attributes. A number of years ago I was dealing with the archival and retrieval/display of enormous medical textbooks in XML, and I couldn't efficiently pull out arbitrary elements (chapters, sections, paragraphs, etc) because of the hierarchical nature of the XML document structure. I had to parse the whole thing to use an XPATH to get the element I needed, and that took too long. (My parser could handle 3MB/sec, and some of these books were over 100+MB.)

The solution I came up with was a program that transformed the documents by flattening them into a relatively small hierarchical structure that represented the volume/chapter/section headings of the book, and a flat list of elements that were small enough to parse quickly. I inserted ID and IDREF elements to link these two parts together, and created an external index of the file offsets and lengths of each element in the flattened list. That let me use simple file I/O to access any element by ID, pull it out of the larger file, and only then start the parsing engine.

It was like the article mentions: my XML file, together with the external index (in a simple Unix DBFile file) was a miniature NoSQL database of the textbook.

BTW, this predated the "NoSQL" label, and was developed after testing of Oracle and the XML databases of the day completely failed to meet performance and scalability requirements. My solution has an infinite capacity to scale; its performance is not impacted by the number of books in the system nor their size. The retrieval and display time of a single chapter or any subelement is a constant proportional only to the size of that chapter, and is not affected by the overall size of the collection. All of the other solutions we looked at got slower as the number of books increased and as the size of the books increased. (I mention this only to head-off any comments about reinventing the wheel.)
