As with most things it is somewhat more nuanced. Securities need people to buy them, otherwise they are illiquid and you can't do anything but stare at them :-). So having them go 'up' on their opening day creates a two point trend line that is up and to the right.

Of course anyone who has been around for a while has seen that IPOs always come down 6 - 12 months after they go out. Generally that is because regular employees will have a lock out period (so as not to flood the market) and that lockout is between 180 and 360 days. The interesting metric is that depending on when the employee was hired, their option price might be much much lower than what the current selling price is, and they will often make trades "at the market" which is code for put them on the sell side, I really don't care how much they go for. And the market maker will fill that order from the buy side with the sales price going down each time they fill up one tranche on the buy side and move to the next lower one. That pushes the price down, and depending on how many people are selling, potentially way down. So you will see a lot of option activity for "puts" at sales at those points as traders try to capitalize on the 'employee lockout dump'.

Of course what the bankers taking the company public do not want to have happen for any reason, is to not sell all of the shares that are in the offering. Often times the bankers will be obligated to buy any unsold shares at the offering price, and if the stock is going down that means the bankers are being forced to buy shares from the client company because nobody else wants to pay that price for them. Generally if that looks likely to happen they pull the IPO like Box did rather than lose money on the transaction.

Its these other factors which favors an IPO with a 20 - 50% up tick in price. It means all of the shares will issue without any overhang for the banker, it also makes sure that people are left with a perception of "value" on the stock (just as private financing round that leaves your shares more valuable than before is more positively perceived than a 'down' round where stock price is lower)

My thesis was very much a recipe for how to make my experiment work. We frequently used the dissertations from former students as reference manuals for their methods. I cranked mine out in 3 months.

Amusing anecdote: This was 20+ years ago, when technical word processing was still a work in progress. Many of my peers struggled endlessly with formatting. My plan was to create a mechanically rough manuscript, get through the defense, then worry about formatting afterwards. It worked, with a hitch: I never got page numbering to work, and ended up pasting the page numbers in by hand. Also, many of the figures are obviously pencil drawings that were photocopied.

This is only a critique of the monograph-type PhD thesis, which I agree that should become obsolete.

Where I come from, a thesis is 3-6 published papers and a 20-60 pages introduction/summary that explains the background a bit more than is traditional in a paper, and summarizes the results.

Yes, the student spends 1-3 months writing the summary part, but most of their time is spent on research and writing the actual papers.

Well. Even a single person can work on more than one task in a day. But much like a single person, the Android team has limited time and energy to allocate.

In my perfect world, the whole Android team spends the next three months doing a bug bash and releasing an Android 6 where I reliably get Hangouts messages and don't have to reboot 2-3 times a week. If some of the Android team is working on stripping down the OS for IoT devices, less time is being spent on that hypothetical bug bash.

Of course this is all moot because fixing bugs doesn't seem to be a priority for them regardless; adding stickers is far more important. :)

Need help choosing an idea/theme for a dev blog
I am going to be starting up a new blog - first time I've ever done this. I'm a relatively new software engineer (professionally, but have been programming since I was 5) and wanted to write about things in the field -- a few ideas for a theme are:

- browser-based game development
- MEAN stack (learning and using)
- SignalR
- ASP.net 5
- Programming against a RaspberryPI or Beaglebone Black

What do you guys think of these ideas? Any feedback is welcome!

This is great, but lately I just can't keep up with the virtualisation changes. I got really excited about google's novm - that's dead now. kvmtools never got included into kernel afaik. qboot will be great, but it looks like it doesn't really support the light IO solutions (like novm's file, rather than block access). Now there's clear containers which is actually kvm, which looks like docker-meets-qboot. And many others in between.

This doesn't seem right, honestly. Half of the projects have the same approach or goals. (quick boot time and no legacy supported) So why do they die and get reinvented every single time?

Something is wrong...

I'd imagine the lack of rhyme is likely due to the fact that English pronunciation is ambiguous. Given only the text, it would have no way of picking up the fact that, say, "here" and "beer" rhyme, while "there" does not.

(Put another way, English text is a lossy representation of English speech.)

Perhaps if you were to feed the IPA representation of each word in alongside the text, the RNN would do a bit better, though admittedly I'm not sure how you would do so.

If this is the case, I'd imagine training it against Lojban text would see similar results.

The sampling is wrong. Picking the largest municipalities isn't picking the largest cities; it's picking the regions with the best political organization. Jacksonville proper has about twice as many people as Miami proper, but you'd be insane to say Jacksonville is a "larger city": Miami's core is way denser and the metro area is four times as populated. Similarly, putting San Jose on the list instead of San Francisco doesn't make any sense. You could include northern San Mateo county and Oakland (which adds up to 1.5M) as "San Francisco" and you'd still get a higher ratio than in San Jose. Cities whose boundaries sprawl are concurrently more suburban and more populous: that's confounding.

A better list would be: New York, Los Angeles, Chicago, Washington, San Francisco, Boston, Philadelphia, Houston, Miami, Dallas.
Sadly, the notion that 'It was tried in <country name> and didnt work so we should avoid it' doesn't really apply to politics. Consider Australia's current internet censorship and metadata legislation, the same laws have been tried all over Europe, the US, Asia and a host of other countries and proved worthless, and yet the government pushes forward with them. Its simply for appearances, the leadership needs to look like its tough on whatever the hot topic of the hour is.

There most likely are explanations. On mailing lists. Where the developers are. Because absolutely none of this is in any way end-user-oriented software. Nobody takes the time to package them up and summarize them like Linux Weekly News does for Linux kernel comings and goings, because there's the distinct possibility that absolutely nobody would care.
Great point.

I don't have applications needing Hadoop right now, but in cases where (for example) I had a ton of data in S3 and needed to make some passes through it then Elastic MapReduce was appropriate and inexpensive.

Also, there are good machine learning libraries available for Hadoop and also Spark, and the overhead of using Hadoop and/or Spark might make sense to have head room for larger data sets without recoding.
If you want to be happy[1] you might want to eliminate the idea of meaning from your life.

Any kind of meaning, as in the idea that there is some goal to work towards -- not just a sense or feeling of such -- will eventually and probably often get in the way of a conflicting want[2], namely to be happy. Say you like to play some game. You do it for intrinsic reasons, because you like doing it while you are doing it. Then you ask the person who taught you this game "What is the meaning of this game? What am I supposed to accomplish?" If the person says "There is no purpose to this game", then you are free. You are free to enjoy the game for itself, because there is no place to go, be or become. But if that person says "Oh, it's very important! You are supposed to learn about things which will be vital for you at some later point!", then that game has meaning Meaning which will conflict from enjoying the game and the moment for itself, instead introducing competing concerns like "am I playing this game well enough? How can I get better? Am I progressing at a fast enough pace?" Do note though that wanting to become better and play well is not in conflict with happiness, or delicious nihilism. It just gets in the way when you start to compromise your happiness in favour of becoming better at the game, or something else.

True freedom is when nothing you can do or make has any meaning. The only impact it has is the joy it brings you in the given moment, which is immediately there and doesn't require any justification for its existence or relevance. It's just there.

I hope to be able to eliminate the idea of meaning from my life.

[1] Experience a lot of good feelings on a regular basis. And it doesn't have to be the overjoyous, jovial kind.

[2] "Meaning" is just a sense of purpose which is tied to doing something which you predict will bring you happiness in the future. But since it is about happiness in the future, it is not happiness per se.
In this case they sold a good chunk of the company, and left nearly $70 million on the table. For a relatively small company, it would be hard to justify that as an investor marketing expense.
They will probably add some IR or optical camera beneath the headset. Not quite sure if they can also pick up some face expression by using the eye-camera as well (like smiling).
I'm convinced that voice pitch, syllable meter, hand gestures, facial gestures, and other forms of non-word emphasis are also crucial to figuring out basic phrase chunking and word types, with minimal interaction, early on.

Seems it would be far harder to infer the basic initial structure from just plain text.

I feel like you hit a borderline-pathological case for the noise reducer with that image. It hasn't just blurred the cross-hatching (? is that what those patterned lines are called?), its completely removed it.

I tried it with just upscaling and no noise reduction, and the result is about what you'd about: a really nice upscale, perfectly preserving all those patterns (as well as the noise, unfortunately). Doing that and filtering in another program might work better.

> Could you really write a bullet-proof case for using our current financial system instead, especially if the roles were switched and we were coming from something Bitcoin-like to a proposal for using fiat currency?

By the way, someone on Reddit answered this challenge. http://www.reddit.com/r/Buttcoin/comments/36p1eq/hacker_news...

"Fiat is like Bitcoin, but with a few new features.

"Rather than using a traditional decentralized system, the currency supply is managed by a semi-independent ruling body, which stabilizes the currency against hyperinflation, deflation (a major problem of the Bitcoin economy), speculation (ditto), and financial attacks. They also provide insurance on bank deposits in case of theft!

"While Bitcoin has long transaction times, this new "fiat" currency has quick transactions through credit and debit cards. These even allow chargebacks, providing you with protection against scams. Fiat is also revolutionizing the world of remittance and money orders, with fees much lower than Bitcoin's through the use of internal ledgers.

"While the Bitcoin network uses massive amounts of power, the new fiat network is environmentally sound and does away with the need to develop specialized ASIC hardware to mine Bitcoin and to maintain a lengthy record of the blockchain. Fiat even has solved Bitcoin's transaction rate problem!

"But one of the most exciting features of fiat is "cash," a physical representation f previously-digital money. It's anonymous (unlike Bitcoin, which records all transactions forever). Because it is a physical item, it cannot be stolen by computer criminals, one major risk of Bitcoin. Best of all, it's accepted by everyone, everywhere- no need for computers, addresses, or block confirmation wait.

"Fiat- it's the currency of the future!"

The work of Nicolas Boulanger-Lewandowski was extensively focused on this topic, see his work [1]. He wrote a Theano deep learning tutorial on this topic [2], and several people (Kratarth Goel) [3][4] have advanced the work to use LSTM and deep belief networks.

For a brief while RNN-NADE made an appearance as well, though I do not know of an open source implementation

There are also a few of us who are working on more advanced versions of this model for speech synthesis, versus operating on the MIDI sequence. Stay tuned in the near future!

I can say from experience that some of the samples from the LSTM-DBN are shockingly cool, and drove me to spend about a week using K-means coded speech. It made robo-voices at least but our research moved past that pretty fast.

The issues with an external battery are:
Phones tend to die when you're using them. This means you're either constantly plugging/unplugging, or you have a cable hanging out of your pocket all the time.
My LG G3 can easily drawn than a smaller battery can supply, so it'll still go dead.
A big enough battery is a large, heavy thing. It will monopolize a pocket or small purse.

From a strictly emotional standpoint, the idea that I must carry a separate battery if I plan to be away from a charger all day is just stupid.
Tvtropes tends to drain the specialness from an entertainment product and reveal the generic components. Applying the same lens to politics results in something like "Yes Minister", where we realize government actions aren't caused by "good" or "bad" actors, but the inherent structure.

Most current crises have a referent in "Yes Minister", including this one - when the PM denied the bugging of an MP's phone. ("He should not have denied something of which he had no knowledge.")

This indicates how few fundamental situations or tensions exist in modern government, and how often they reoccur.
Isn't that what he was trying to do before you forced yourself aboard?
Karpathy states in the blog post that word-level models currently tend to beat character models, across the broad field of NLP related RNNs. But he argues that character models will eventually overtake (much in the same way that ConvNets have "replaced" manual feature extraction).

That said, I think the RNNs here are limited by the corpus. They need to be exposed to more writing. Even if all you want is a Shakespeare generator, you still need to expose it to other literature. That will give it greater context, and more freedom of expression and, dare I say, creativity. I mean, imagine if all you were exposed to your whole life was Shakespeare. Nothing else (no other senses). Even with your superior mind, I doubt you'd generate anything better than what this RNN spits out.

So yeah, it needs a large corpus to build a broader model. Then we need a way to instruct the broadly trained RNN to generate only Shakespeare-like text. Perhaps by adding an "author" or "style" input.

They do it verbally.

I'm the author of a number of open source projects, and some of the messages I've received are just insane.

The latest thing is... get a load of this... it's now no longer good enough to give your code and your service away for free. Nope. It has to be free and permissively licensed, so that anyone who wants to take it closed and put their name and a price tag on it can do so without compensating you in any way whatsoever. Anything less and you're not serving "the community."

I have to ask what kind of community this is. OSS was envisioned as the basis of an information gift economy, not a bunch of "takers." Nowadays the takers are increasingly corporations, not even individuals.

That's why my larger non-trivial OSS projects are and will likely remain GPL or similar. I do sometimes release trivial stuff under public domain or nearly-so licenses, but things that take years of work? Sorry, but you have to give something back. At the very least you have to acknowledge its authorship if you use it.

Luckily these attitudes are far from the majority, but I still think it's worthwhile to call out obnoxious trash for what it is. I've come to the same opinion with regard to piracy, especially industrial-scale piracy. The thing that really bothers me is when people actually get holier-than-thou about it. I have more respect for you if you just say "look, I'm a cheap greedy jerk and I want free stuff." At least you're admitting it. But please do not try to act like your wanting free stuff is some kind of grandiose liberal social statement that's helping make the world a better place, because it's not. At worst you are helping to devalue labor and destroy peoples' livelihoods. At the very best you are accomplishing nothing.

The last thing I want the author of something as beautiful as Space Engine to see is to visit the HN thread about their project and see a bunch of whiny takers berating them about how they're not allowed to take take take on terms that please them sufficiently.
At first I laughed but then I got it.
Very good point. We shouldn't necessarily.

The benefit of a linear estimator is it is a lot easier (both computationally and algorithmically) to fit/solve a linear model than a non-linear model. Thus, there are advantages to linear models. Further, despite it being called linear, the model can actually be quite complex. It only needs to be linear in the model coefficients, but the regressors/independent variables don't have to be linear. Thus, you can make one variable the square of another variable or add a variable that is the interaction of two other variables. By doing so, you can add non-linearity while still using linear methods to solve the equation.

Ok, so then once you see the value of a linear model, then the next question is why we would want the best and most unbiased. I think those are rather obvious.
