> So it's understandable that Pixar, which has to render a huge number of frames at huge resolutions, did not traditionally use it much.

Do we have any ball-park estimate of how long it takes Pixar to render a single frame of a movie like Monsters U?

EDIT: Many people are mentioning it's done massively parallel, which I meant to include in my question. So, what I mean is, how long does it take to render a whole Pixar movie?

How can you say China is "economically free" with a straight face? Surely people can't believe this. Try to import something into China. Try to take RMB out of it. etc etc. It's one of the most centrally planned economies out there with much of its wealth generated by state-owned companies.
I don't think this is so true. Angular's $resource has different goals and functionality than something like ember data. To me, Angular's $resource looks closer to Backbone's sync methods.

Things I don't see in Angular's $resource:

* Identity map

* Support for switching adapters (e.g. online/offline)

* Relationships
Well, technically I suppose systemd doesn't, journald does (and systemd requires journald, and journald is made and shipped by the same people....).

I'm not opposed to a "next-gen syslog", but yeah, that isn't a push that should be done in such close connection with systemd. A better approach would be to make rsyslog more than just a syslog daemon and build up a new protocol and storage format with it, with the full intention of standardizing it. (the syslog protocol is a pain in the ass, particularly that hard limit on facility numbers... Fix that first, then roll from there. Make rsyslog treat syslog like Vim treats vi: capable of falling back to compat mode, but better by default.)
Ah, thanks! I chuckled :D
> Unless I'm reading this blog post horribly wrong, when you click on "Recommend" you don't direct this recommendation towards anyone at all. It's simply "I mark this with my stamp of approval, which in turn will help surface this good content to other users of this website". There is not a social angle to this at all, nor any sort of directed sharing.

You're not wrong - that's exactly how it works! I must apologise for the post being quite unclear; it has been quite a while since I wrote anything :)

Discoverability is very much one of the core concerns for me, as I feel it's lacking elsewhere. I like the idea of rewarding people that others agree with, as that could help encourage users to recommend more often whilst also making exploitation of the system more tricky.

This is still very much in its early stages and I'm keen to improve on it. Thanks for the great feedback!

Something is missing from this discussion. The sample problem in the xkcd comic is from a class of NP-complete problems, but being small, it has a solution in "pseudo-polynomial time"[1] that can be solved by a variety of tools, as demonstrated in these comments.

Even though this simple example can be solved, the general problem (from a set of N integers, find all subsets that add up to a given integer x) is nonetheless NP-complete. The method of computation (Excel, Prolog, constraint programming, Turing machine) does not change this fact.

This happened to me on Mint.com. I use a password manger as well and I generated a 32 character password. It saved successfully, but once I'd log in, it'd kick me back letting me know that my password was incorrect. After about 15 minutes of confusion and multiple password resets, I figured out that passwords can only be 16 characters in length (or, that worked at least), and anything longer than that amount was just being ignored. There was no explanation about this at the time.

"CodeIgniter is dead" - Phil Sturgeon
Bad headline given the use case which not a currency issue but rather how to feature quality content that is not as popular:

* Discovery: Good but unpopular content is being buried by popular content

* The noise makers are the taste makers: What is popular is being decided by the most active users

* Popular begets more popular: Rankings that are based on popularity only reinforces the popularity of top-ranked items.

Some communities may decide that this is not a problem and therefore ranking content by Likes works as is.

However if you want to address those issues, then yes, rationing the available Likes is one way to approach it. You could also weight the ranking formulas by percentage of Likes per user (ie. users that have older accounts and give out less Likes overall are weighted differently)

OT: (fanboi alert) I think it's really cool that you're posting here. Pixar is one of those places that I think would be really really cool to work for but that I don't have the skillset for. For the record, I have an original print of the RenderMan book that I read cover-to-cover when I was a kid.
I think that the word "Science" deserves some attention. I completely respect the data structure side of a data scientist but more often than I'd like I find people addressing themselves as data scientists being very good as software engineers, but not as good as statisticians or model builders.

I may be wrong but I disagree with who says that the difference from a data analyst and a data scientist is that the data scientist is a software engineer.

I would say instead that the difference between a software engineer and a data scientist is that the data scientist is a scientist that has a strong CV in data structures and algorithms, as well as in (maybe pure) science, with experience in statistics, math, or physics, and that knows very well how to work with models, test hypotheses, spot patterns, anomalies etc...
Software Development for Infrastructure [pdf]
My take on data science, and what makes it distinct from other fields, is that it combines a knowledge of the business logic (i.e. software engineering) with knowledge of statistics.

For example, a statistician might wonder exactly what a particular ID referred to. Does it mean a person, an IP address, a single "session". They could, of course, find this out, but the data scientist would already know this.

Similarly, a software engineer might wonder what information they need to be collecting from the user. The data scientist knows what analysis will ultimately be done, and so knows what information must be collected.

So data science combines statistics and software engineering, and this is useful because it allows a holistic view of the data analysis process, from the collection of data, to the statistical analysis of the processed data.
If you clear metadata, the following pathological case results in an inconsistent read:

* x = 0 and y = 0, starting out in the "good" state with metadata cleared;

* client A reads x with no metadata, then for whatever reason blocks or is delayed;

* client B writes x = 1 and y = 1, completes the transaction, and the metadata is cleared;

* client A reads y = 1.

This shouldn't be an issue unless you aggressively clear metadata and have a long-running client.

The issue is causation. The American mantra for the last 50 years has been that freedom causes economic development. What we're seeing with China is economic prosperity causing increased pressure for political freedom (though at a dramatically slower rate than I think Americans circa 1960 would have predicted).
definitely seems useful
This distinction is frivolous.

It's a writer just seeking to milk the whole "flat design" thing even more by categorizing small variations as a whole design movement. It's no coincidence that a company selling a kit has the most blog posts dedicated to it. flat and almost flat design have the exact same aesthetic.

Moreover, pegging designers to a trendy aesthetic is ridiculous.

Fascist? Really? As far as I can tell Singapore isn't nationalist at all or totalitarian. I'm not sure you could even call them outright authoritarian, fines for large organizations criticizing the government is bad but it's not nearly as bad as arresting individuals for the same.

They're not a dictatorship either. Their political structure does have a working set of checks and balances that does seem to prevent an individual at the top from doing whatever they want. Call them a "paternalistic oligarchy" if you want, but "fascist dictatorship" is way out of line.
In defense of the Facebook sign up, how about issues of safety? Meeting a stranger online can be risky. Forcing signup via Facebook helps provide data that users can use to perform a due diligence on the strangers they might be meeting. It helps hold people accountable if they do decide to do something malicious offline. Perhaps LinkedIn might be better, but I don't see a problem with utilizing some sort of identity related social sign up for this idea.

I think more research is needed.
I would also add that econometricians are highly focused, almost exclusively focused in fact, on finding causal relationships.

This means that descriptive work such as clustering, dimension reduction, is often either ignored, or considered as a kind of pre-processing before the real work starts.
Comparing raster graphics from 12 years ago to ray-traced graphics from today isn't a fair anyway. Part of why raster has persisted against ray-tracing for so long (despite numerous predictions to the contrary) is that raster graphics techniques are constantly improving.
I have considered more complex systems (i.e. dynamically altering the value of recommendations) and it's something that's likely to feature in the future. However I needed a simple solution for now whilst the site is developing, and I took a rough stab at it!

I'm very likely to adjust the limit (if not alter the system in the future) based on how it's used, but I'm waiting for more data before I make that jump :)

Pixar's generally ahead in terms of story, animation (they hand-animate everything) and look (shading and lighting), but in terms of pure tech, other companies like Weta, ILM and SPI are generally ahead of them as they work on multiple shows at once and per year.

SPI have been using full GI pathtracing with Arnold renderer for the last 5 years, and Blue Sky (studio which did Ice Age) has their own GI raytracer they use as well.

Also, Pixar don't actually have that big a renderfarm - they don't need it. Other places like Weta and ILM have renderfarms that are much bigger, but are used for multiple productions at once, and for doing things like compositing and fluid/cloth/physics sims.

Things I didn't learn in my econometrics classes that are used all over in data science:

1) Machine learning techniques for analysing data sets as opposed to parametric models

2) Clustering (k-means, etc.)

3) TF / IDF

4) Using a variety of data sources / tools - my econometrics educations was heavily Stata dependent. Learn a little bit of SQL, R, and Matlab so that getting up to speed doesn't take you longer than a month.

Another benefit to prefixing everything is that it makes possible an automated module selection/build system. Point it at your markup/codebase and it would select only the modules that your site uses.

whether it's "what the audience needs to hear" is irrelevant

A charitable interpretation of his meaning leads to the same conclusion you have. Maybe what he means is "Every talk is for an audience, and it's the speaker's responsibility to say what the audience needs to hear so they understand the point"?

100 years? How about 10 years? Our inability to predict the future works on much shorter timescales than he seems to think. Why the emphasis on 100 years?

Because he's referencing a talk given at the 100th anniversary of CalTech.

Other than that, yes, I agree, it did come off as a bit pretentious. But I feel his point, he wants to work on things that matter to him, for the time frame he defines.
So very true! In fact, having worked at an Apple store, and later on the products sold at the Apple store, I'd venture to say that Pixar's process is probably precisely like the process behind something you would see at an Apple store!
I don't believe there is a difference legally. Courts tend to disregard the label applied to an amount.
http://bikes.oobrien.com/newyork/ is a bit more comprehensive.
The difference here seems to be that they successfully decrypted one of his drives and were able to prove that there was child pornography and that the drive belonged to him. At that point, as I understand it legally, he can be compelled to decrypt the drives because they already know he was possessing child pornography on at least one of his drives. It would be different if they did not actually know he had child pornography on his stuff.
> Well, technically I suppose systemd doesn't, journald does (and systemd requires journald, and journald is made and shipped by the same people....).

Technically indeed. If you try to forcibly disable journald, it causes causes dependency failures that result in you dropping to an emergency prompt.

Of course this doesn't stop Lennart Poettering from using the existence of separate but interdependent daemons as 'proof' that systemd isn't a monolithic ball of mud.

> I'm not opposed to a "next-gen syslog", but yeah, that isn't a push that should be done in such close connection with systemd. A better approach would be to make rsyslog more than just a syslog daemon and build up a new protocol and storage format with it, with the full intention of standardizing it.

Make rsyslog treat syslog like Vim treats vi: capable of falling back to compat mode, but better by default.)

Agreed. This is what Apple did with asl(3); it's a modern syslog replacement that happens to still support the syslog protocol and syslog(3) APIs.

There's no reason a modern logging daemon can't be portable to other systems, too; it shouldn't be doing anything so crazy as to be impossible to run elsewhere, whereas since systemd is an intentionally non-portable kitchen sink, no other UNIX is going to run with journald.

Not the OP and I sort of agree with you on the language front.

> Is it really that black & white? ...

It is a bit troublesome if the only way to try out a new service is to give you access to Facebook data (which likely includes a whole lot of data that is unnecessary for your service); it is asking for a whole lot of trust and my threshold for trying out services that require it is a lot higher than normal.

Of course it may be that many startups actively do not want people unwilling to provide FB data to try out/use their services. In that case we are in total agreement ;)
Hey thanks! Especially for the MVP, I think you're absolutely right about the abuse part. As for the login/recovery, have you had any experience with signup rates using Facebook/Twitter authentication? Reinventing the login flow seems like a bad idea to me at this point.

God that chart is terrible.
"...after devoting “substantial resources” in the case, FBI agents apparently have been able to decrypt one of the drives. The government argued that because it had found “numerous files which constitute child pornography..."

So if they've found the evidence they're looking for, why keep pressing? Because they don't want to spend the extra effort to decrypt the rest and are looking for a plea bargain?
If you're blocked, why don't you just contact the scrum master directly when you are. Why do you have to get everyone together to mention it.
I've seen you write something similar to this before, but I don't agree.

Counterexample: a good friend of mine specialized in computer graphics where he did a lot of math-heavy research. I specialized in machine learning where I also did a lot of math-heavy research. We are both full-time programmers who choose our tools and flexibly work on interesting projects, but he would never get hired as a "data scientist", whereas I did. I think anyone who has specialized enough in something that's useful to a company can find a good, flexible job (e.g. my graphics friend and me).

The fact that the term "data scientist" is so ubiquitous simply means it's cooler/more useful than other specializations right now. Some companies may get away with abusing the title because it's so vague, but it does mean something to companies that actually know they need one.
Now that Pixar is only ray tracing, can real time move to scanline? I'd really like to see a lot more smooth shapes and complicated geometry in games if possible.

I wish the 10gen folks would do some work on various issues that have been in MongoDB for a long time. For me the most serious one is data size. Storage is pretty terrible, especially compared to CPU these days. I would far prefer the use of more CPU in order to reduce storage.

Records in a collection mostly use the same set of keys. Every record includes the full key which makes the storage that much larger. Strings can interned and replaced with a far smaller numerical token to reduce storage. (I'd be happy for it to be attempted for string values as well.)

The other is compression which is a straight forward cpu versus storage tradeoff.
