I'm not sure where the article got that 50 Mb/sec figure from, but it sounds a bit low. Uncompressed, it's more like 50 Mb per frame - 1.5 Gb/sec (4096x2160, 3 channels, each channel is 16 bits, up to 30 frames/sec).

According to their tech specs page* there are two compression options: 18:1 and 3:1. The former gets it down to about 84 Mb/sec, but it's difficult to know what kind of a quality hit you'll be taking. With the latter it's still 500 Mb/sec.

Film-makers generally want to capture source footage at the highest quality possible so I'd guess most will film at the 3:1 compression level. If that assumption holds, 2 hours of footage is approximately 3.5 Tb of data.

That is still a fairly manageable amount of data though. For comparison, The Tale of Despereaux - an animated movie which came out in 2008 and started production several years before that - filled up a 192 Tb disk cluster.

Edit: I think I might have made some incorrect assumptions about the REDCODE raw format, so my figures above are probably wrong. Sorry for any confusion!
After about 10-15 years working with many different systems that one way or another store their data in a RDBMS, all I can say is that I agree with what you wrote. ORM-wed code is a nightmare, 3-5 years on. When the ORM trends have shifted to something else, and the original people who implemented it or selected the framework is long gone.

Ill take a messy system with hand coded SQL over that any day, atleast then you have a chance to refactor.

Also, its not that hard to implement a pluggable data access layer (that uses hand written SQL). The most important thing is to keep your RDBMS data model separate from your application model. These two will be intermingled when you are using a ORM, in my experience.

It still needs work.  What do you guys think?
I don't know if you've heard about the Empathizing–Systemizing theory (http://en.wikipedia.org/wiki/Empathizing%E2%80%93systemizing...) which was originally developed to explain autism, but basically engineers typically have very strong systemizing traits. Surprisingly, this also makes them good at certain aspects of high-level planning. I suspect that the current CEO Tim Cook has an excellent systemizing (as well as negotiating) mind, which would partly explain his great deeds in the supply chain operations.

Some people would argue that it was Wozniak's engineering mind that made him not want to pursue management. I would argue that the engineering mind is actually quite useful in management and that a lot of business leaders possess it (think Bill Gates). My hypothesis is that if Wozniak became as ambitious and controlling as Jobs was after the two met, the pair either would have fallen apart violently at some point or would have created an empire the size of Microsoft early on.
This is blowing one element of design way out of proportion. I'm not a huge fan of brown leather, but to me, iCal is much easier to look at and functionally clear than Google Calendar, and part of this has to do with the use of texture.

When I open iCal (in the cloud or desktop), my focus rests naturally on the actual calendar because the texturing puts all the settings in the background. I like that the calendar itself is elegantly centered on the screen. I like that it has only settings I'm likely to use and that menus I use less the calendar selection column) are completely out of the way.

I don't have any problem using Google Calendar, but it's flatness annoys me. The calendar is lumped into the bottom of the screen, which is kind of an odd de-emphasis of the most used element of the app. The banner and many controls I don't use all the time have the same dark hue as the current week. Search is disproportionately (for my calendar usage, anyway) prioritized in terms of screen space. The whole left column (with the garish "create" button and a mini calendar) is basically useless.

Yeah, Apple needs to go easy on the leather (surely something could be more consonant with that silk texture), but ultimately Google has a lot more to learn from iCal than vice versa. And I think iCal actually shows, albeit imperfectly, that texture does have its place.
But It was very informative, as he explains what he is talking about since the definition of an ORM seems to be quite different for different people.

For me it also means anything that tries to generate SQL.

Lately I've been using RedBean ORM for my projects. It lets you write your SQL (no query builders or anything stupid), but creates tables, columns, and foreign keys on the fly.

Here's some RedBean code from one of my projects:

I suspect that they are counting the processing power of the Pandaboard GPU (most of these types of comparisons do).

It's not really a very useful comparison - most general purpose server software doesn't make much use of the GPU.
Watch Google's Search Page Do a Barrel Roll
Sorry, perhaps it was my fault by starting on the criticism. It was just meant to be an honest observation.

I think the font looks great and I appreciate the effort and time it took to create this font. However I see it more as an art piece. Just like an artist might have painstakingly created a body of work for 5 years, just the effort put into it, makes it impressive. To someone (a collector, a gallery) the piece might be worth $200,000, to me though, it might be or worth $0, just because I don't like it or I am shopping for utilitarian things at the moment. "Would this piece help me code faster?" kind of reasoning. So maybe it is just the wrong market.

There might also be a luxury market out there for fonts, someone who has the latest and greatest set-up and has deep pockets who just needs something extra ? A book publisher? An OS vendor?

When you build a site with CSS you’re over-riding the browser’s built in stylesheet. If you don’t provide your own CSS then the site is readable without, because the browser lends basic visual meaning to semantic markup.

Think of screen readers as having internal styling. Links are read in a different voice because the screen reader is applying a default audio style to the page.

Audio styling is part of CSS2.1 [1] but isn’t widely supported or widely written (classic chicken/egg problem). If you want to you can (at least theoretically) over-ride a screen reader’s default presentation of your markup.

It is probably pointless for Google to use humans to read mails, especially the mails of regular people. And it is certain that they use automated processing of the information in the mails.

A most relevant question would be: Does Google match the profiles of its mail users to high profile people, such as company managers or other rich people who can be easily found on, for example, Linkedin? If so, does Google automatically filter their email in order to predict, for example, the stock market?

I'm not saying every website should work perfectly without scripts - I know full well what I got myself into when I started using all these filters. What annoys me are websites which are completely un-fucking-readable without dozens of scripts, x-site requesting and/or (which is the worst offender by far) Flash.

I'm fine with whitelisting your website so you don't have to bother with CSS voodoo. I am willing to whitelist your image/static domain so your site can load its content from there. I'm getting annoyed if your website requires more than three scripts and/or cross site requests to work properly, but I can put up with it depending on how much your site interests me. And finally, it's an instant ^W if I open up the NoScript menu to find dozens of scripts, trackers and other shit while your site looks like a page from a broken printer and is unusable.

'Art works by different rules' is such a cop out for hippies to excuse time-wasting. What added wealth to the world is created by doing it the hard way?
Ah - well I guess the spec is written with the future in mind when everyone's got their servers configured correctly. Until then nobody has their servers set up right so I think it would be practical for browsers to be a bit more relaxed. Right now we're seeing a lot of games on servers without this MIME type, and the browsers respond by requesting all files from the server all over again every single page reload, probably wasting a lot of bandwidth and making HTML5 games look bad. I think there's a good case for a bit of relaxation on the browser side - standards compliance is good, but not if the web isn't ready yet.

It's really all about factoring. You'll notice now that you have model logic in your controller. If you want to reuse that elsewhere, you'll first have to extract it to another class. That class is effectively a SQL generation library, except it's not useful in a general sense and it's not as well tested. The more you do this, the more you converge on reinventing a full blown ORM.

I'm not saying there aren't downsides to ORMs, but the counter-arguments to SQL in your controller are pretty obvious.

The concept of ORM is a subset of the concept of SQL. When you're adding complexity and/or overhead to something to achieve a subset of functionality, you'd better have a damned good reason to do so. I'm still waiting for a reason that doesn't make me roll my eyes...
Generally I agree doing SQL queries on your own. I'm also not really an ORM-Fan because it's really hard to debug and difficult queries are more difficult to construct using an ORM.

But doing your SQL Statements in the Controller is just not the way to go.. What if you need the same query on different places?

What I like about good ORMs (like Doctrine or the ActiveRecord of RoR) is the migration part.
Maybe there should be a tool which only supports you in creating the tables and handling migrations.
Media Composer 6 – User Interface
I'm beginning to develop a theory that this kind of Apple-fandom is somewhere between being an audiophile and a mentally contagious form of OCD.

I've had complete strangers, totally normal people (picture the exact opposite of a stereotypical techie), raving to me in a shop about how great their Kindle is because they saw me play with the demo device. That's a home run in anyone's language.

But Aaron, who seems to have trained himself to appreciate the finer details, has this joyous experience ruined for him in much the same way a wine snob can no longer enjoy an even passable glass of wine.

I guess the missing factor is how much effort is expended on these nicities versus the return on that investment.

If the text below a main icon is cut off, is that a sign of how shoddily the entire thing is put together, or is it simply not important, compared with the many benefits the device gives you?
I might not have understood properly, but the idea is for these companies to basically always be "losing" money on paper. Many popular movies are "flops" on paper because of accounting reasons. If these companies have 100 RED cameras lying around, creditors will have something to come after.

Another benefit from the split continuing was the smaller the root filesystem, the bare bones needed to get up and running, the less chance of filesystem or data corruption occurring. This meant your had a bootable system with which to repair the other bigger filesystems instead of having to boot from tape.

It is so simple:

- If you do quick ad hoc script/page - use straight sql with mysql_query

- If you extend it - use something like PDO

- If you build real application, you have to use Model layer. And no matter what you prefer at this point - you'd better to put everything behind Model be it PDO-based queries, some dynamic objectish query builders or full-scale ORM like DBIx::Class (sorry, this is for Perl, not very familiar with something like this in PHP. If someone know good analogs in PHP - please post links to these).

Right tool for right task - this is what important to keep in mind.

PS: Sorry, but seeing straight SQL in what looks like an action, is really hurt my eyes. If you opted for MVC framework, you'd probably want to push all SQL into model and leave meaningful calls to it.

Without knowing anything else, 90 days sounds like the amount of time sellers extend credit to Apple (30 and 60 days are also common). Usually such terms come with slight discount for early payment. Good cash management practice requires that they pay on the last day they get a discount or wait until the last day to pay.
