That is why I put "discovering and disseminating best practises" in there. We can all guess what the best way of specifying and implementing the standards is, but why not experiment and find out? This ranges from the setting of the standards (eg how detailed they are), through how they are implemented. And of course all the other things (eg reducing hospital infection rates, improving overall hearth health).

Still with the learn to code meme? In addition to all the reasons that @codinghorror raises in http://www.codinghorror.com/blog/2012/05/please-dont-learn-t..., I have a one more to add.

The altruism of it all stinks. The meme is being pushed by parties (non-profit or not) looking to gain from teaching people to program (after convincing them that they absolutely should). While it's true that learning to code is beneficial to some (I don't doubt that) no one talks about how these friendly, helpful, code tutors might be exaggerating the demand for reasons of their own. While you might be trying to help people out, you're also trying to push your startup or non-profit.

I like the idea of better aligning education with job demand; something I don't think higher education institutions are particularly concerned with. That's practical and I wish we did more of it. Similar to these learn-to-code websites, colleges could care less what you do with yourself after you've paid your tuition.

What I liked about the code.org celeb video were the recollections of first programs. Like a first kiss, you never forget your first program. No matter how simple it is, that feeling is awesome. And if you're made for it, you want to do more, you want to make it better. That's the spark that, if you have it, puts you on the unending journey to being and becoming a coder.
> I think Diaz just pointed out that these claims are dubious at best

He did no such thing. He just pointed out that you can get the same benefits from using x264 directly.

Most people just take the h264 stream they got from their phone / camera / BluRay rip. These are horribly compressed. x264 can consistently improve those without degrading quality by 30% without much tweaking, and by 50-70% with some tweaking.

Apparently, Beamr saves you some tweaking. Diaz' claim is that the tweaking saved is ridiculously minimal and does not warrant all the hyperbole around beamr.
Given the callback nature of the Django templating library with template tags, includes, and other goodies, it is not as simple as "call foo_template() and return string". As soon as a template tag is involved, internal data structure needs to be exposed, with makes * everything* much harder.

Funny I though C++ did exactly the same thing. Where are the L1, L2 and L3 caches references, multiple opcode execution pipelines, processor instructions ?
mhluongo -- Love that you specialize in search and have author profiles.

You guys should get in touch with the peer library guys, send me an email if you'd like an intro. I'd love to see more collaboration in the space.

Internet Archive (archive.org) is also interested in contributing to the space and has been super helpful in aiding our efforts at open journal.

I think the three biggest problems in the space are (1) discovery + accessibility (including open-access), (2) collaboration (sharing, commenting, contributing), and (3) quality assurance (maintainability, scm-backed, repeatable research).

There are many solutions to target discovery and accessibility but I'm (as an academic) personally dissatisfied with the level sharing/collaboration/openness, the lack of community, and the lack of standards in academic research. I think the world needs for academia and research what github did for social programming.
Best 5 Ways to get more Energy Now (www.wisestep.com)
Then 4 o'clock rolls around and you're ready to hit the vending machine, try these instant pick-me-ups instead

There are a zillion of ways to get a jolt of energy -- a triple-shot latte, a piece of chocolate cake, a chemical-filled energy drink. But most of the quick fixes like these that many of us reach for when we're pooped aren't exactly healthy. And worse, they leave us with a monster-size helping of guilt followed by an even bigger caffeine or sugar crash.
So, arel you feeling a little sluggish? Opt for one of these healthier options:

Down a glass of water
Next time you're feeling like you want to take a nap under your desk and you're tempted to hit the office candy stash to stay awake, head to the water cooler instead. When you're dehydrated, your body isn't getting the optimum amount of energy-boosting oxygen, and chugging a glass of H20 can immediately change that.

Get your giggle on
Laughing out loud has been shown to release endorphins, which make you feel happier and more awake. If your co-workers aren't exactly making you chuckle these days, hit your favorite YouTube channel, watch clips of your favorite funny movies, or call a friend who never fails to make you giggle.

Walk on
That's right: Get up off your bum, step away from your desk, and go outside for a 15-minute power walk. That's all you need to get your blood flowing, get more oxygen circulating throughout your bod, and prompt your brain to release some of those energizing endorphins.

Snag a protein-filled snack
Yes, a piece of banana bread or a bagel with cream cheese might be what you're really craving, but carbs will do squat for your energy. On the other hand, eating protein will increase your mental alertness and energy. That's because foods rich in protein contain an amino acid called tyrosine, which elevates the feel-good brain chemicals dopamine and norepinephrine.

Take a smart supplement
You could head to the convenience store for a can of your favorite little energy drink -- but it's smarter to keep a stash of all-natural energy powder packets in your purse. These are so handy -- just mix into a glass of water, drink up, and watch your energy skyrocket.
I think this is a good point, but I'll take it a step further. The kid that likes drawing doesn't have to be a programmer, so stop trying to teach it to him and let him draw without the constraints that programming brings. We don't all have to be the same.

It is very easy to say "Django has large design problems" and go on about how it "imposes ilegitimate requirements". Truth is that Django is a framework and by definition, frameworks give you a way/structure to do things. If you don't want a framework, then there are several other options.
The strength of Django comes from the huge quantity of packages you can swap in/out. You mentioned you don't like the Django Template engine and that Jinja s better. Easy to swap. Don't like the authentication? Swap it out for something else or use a custom one. Don't like the ORM? Dont't use it... sadly you'll be missing out on south which has saved me from sql schema and data migration headaches. Caching? Redis, Memcache, or write your own. It plugs easily. Async processing? Celery is only a few lines of code away. Indexing with Sphinx search or Lucene is trivial. Want to add automatic CSS/JS minification + bundling + sprite generation + cache busting? There are django apps for that. Need analytics? You only need two methods for middleware. I could go on forever... The point is that this is exactly what I expect from a framework. If the framework doesn't do it, the somebody has to - and that means it is me.
And when you need generics...
Rs 25 is actually ~<$0.5
I've spent a fair amount of time (over) optimizing https://starthq.com and would say that network latency needs to be at the top of the list of things to look at.

The solution has been to serve static HTML, i.e. the index page of the single page app part, with a one hour cache expiration and links to other static resources (JavaScript, CSS, images etc.) decorated with their E-Tag and loaded from a CDN. For non static pages the set up is the same, but the caching time is lower. The static resources have far off (one year or so) expiration headers so are cached permanently.

By using a CDN for all your assets you can reduce a 200ms roundtrip to 8ms for all users worldwide, bringing the page loading time to way below 200ms with an empty cache and well below 100ms with a primed cache since you still need to do an XHR to check the login status.

Small time saving tip: if you go with CloudFront, go all out and use all edge locations - it's cheap. I tried using Europe only at first only to eventually find out that I was still being given an edge location in the US despite being in Finland.

The important underlying issue that some people take for granted, and some are completely unaware of:

Most h264 encoders suck. If you take an h264 recording from your camcorder / phone / ip camera / blu ray rip, and push it through x264 (and no special configuration), you usually get 30% bit rate reduction with no loss of quality. With tweaking, you very often get 50%-75% bit rate reduction with no loss of quality, but you have to actually tweak. (e.g., I'm getting ~65% bit rate reduction on h264 streams coming out of Axis IP cameras by running through x264 with -tune slow ant no other change).

Beamr's claim to fame appears to be that they automate this tweaking. Diaz' claim seems to be that "--crf 18.5" is a tweak that can consistently deliver better bitrate reduction than Beamr.

My opinion: If you can use the x264 commandline, Beamer is probably overpriced for you. But if you're a professional photographer with no serious computer skills, Beamr might be useful for you. (Assuming they actually deliver something better than --crf 18.5 ; a claim of which I have no knowledge, but I will assume for the sake of argument)
Indeed. Stuxnet is clearly the hack of the century, so far.
I certainly do get the sense that medical progress has stalled. Perhaps all the "low hanging fruit" has been picked and future progress will be much harder.

As the article mentions antibiotics were both a lot easier to develop and had a much bigger impact than genomic research - at least so far. It sure seems like we have made very little overall progress even on targeted diseases, such as cancer, despite vastly increased spending. Spending on both healthcare and healthcare research have roughly doubled in nominal dollars since 2000 with little overall impact.

I understand that, at least in the US, healthcare is fundamentally broken - results have little connection to costs. But is this enough to be holding back the entire economy? Is tech's impact really just smaller than we think? And are other sectors, especially government activites, also lagging behind and thus dragging down overall performance?
There is good progress into growing organs at least:

The sad truth is that all the open source video editors are like that depending on what you're doing (with the possible exception of OpenShot, which I found to be reliable but limited).

In short, I found no FOSS video editor that did what I needed reliably out of the box. Given that problem, Cinelerra at least came close, the code was readable, and the design sound. Its biggest problem is that its file loaders/exporters are all old and bitrotting so they have become unreliable and crash-prone. For my stuff, I use raw video and so don't hit those problems.

In the process of making Episode 2, I wrote a new compositor resampler and a new color grading filter for Cinelerra (named Blue Banana). These should be appearing officially in the next major release. I hope to have some more file loader work done by then too :-)

What points did you make? You said you wouldn't continue with the lack of NATO-backing because you have more karma than me or whatever you meant by that.

I don't ignore nor support the things that go on in the current regimes ceteris paribus. But I do support them over, in North Korea's case the USA and UN, and in Syria's case the FSA.

I could provide more links to news sites but it's obvious that despite your claims of my closed-mindedness, you are unwilling to listen to any other points of view than 'freedom® good, everything else bad'.

Your fourth point (if you can call it that) is mostly just ad hominem. Who's the idiot again?

> Many open source products seem to just query a URL and direct you to go download stuff. With SSL essentially broken, that's gotta be a bit risky vs. MITM.

There's nothing stopping one from linking against their own copy of an SSL lib, and supplying their own list of trust anchors/trusted CAs. I've been wondering for a while why lots of apps (e.g. mobile apps) don't do this more often.
Meanwhile, the kid who likes programming will probably be drawn to it naturally, as well. I know I was, a long time ago. I can appreciate wanting to lower the barrier to entry for such kids, but I honestly don't think it's excessively high to start with.
Sir here is a Microsoft gold partner who puts nearly £1m a year in business their way as well. I'm not a reddit whinger and Microsoft hate monger.

They treat us like criminals by throwing us through audits, never fix a defect we raise and stop us ordering pizza through trivial bugs which may or may not also affect our 2mloc financial platform.

So, no apologies due. And if you work for MSFT, you're adding to the problem. 94000 people doesn't mean it isn't a ship of fools.

And for reference, its not going to be pizza that kills me - I have a degenerative neurological condition (neurofibromatosis) that will get me first.
>I wonder if perhaps your people just don't have much exposure, because the templating in Django is awful compared to Mako/Jinja2, the ORM in Django is awful compared SQLAlchemy, and most of the useful features of Django are easily available in Pyramid or Flask, yet these systems are unobtrusive and simple.

Define awful in concrete terms.

I've not been much constrained by Django in any way.

Even if all of those are "better" in some spec-listing way, Django could still be better by offering better integration for it's tools.

Like the iPhone, in actual use, beats phones that are better than it "spec-wise".

> your keyboard, mouse, and big screen...the tablet interacts with them simply by being in their vicinity

Bluetooth and Intel's wireless display standard [1] are here already.

Support for these technologies in common devices is another matter...especially considering that wired devices are cheaper, don't suffer from RF congestion, and don't need their own power supply (at least in the case of keyboard and mouse).

"OS X isn’t designed to behave differently while on
different types of networks"

Funny. This was exactly one of the justifications for writing launchd. "daemons" would be signaled on state change, like a network state transition. This behavior would isolate applications/developers from explicit dependency management.

Also, mobile radio prototypes are built all the time. And as noted a lot of hardware ends up on ebay/craigslist. Ironically that's all dvt hardware, not actual proto builds.

Let me just say having migrations is a "good thing".

The point you make here (and one made by many others) is a straw man/reductio ad absurdum argument.

People who advocate that everyone should learn to code (like myself) to not advocate the absurd conclusions that are used by others to refute this standpoint.

I do think people should learn to code. This does not mean I think:
1. Everyone should be a professional programmer.
2. "Everyone should be the same"

You can make similar arguments to a person who says "everyone should learn to read," but then you misunderstand the spirit of the discussion.
> as non-profits can also fund research

They can, but the reality is very few are really prepared to do a good job of it and even fewer have the resources to really fund the portfolios relevant to them in the same way other institutions (gov, some large corps, etc) do.

The non-profit sector has a bunch of hard working folks with great goals and there's a bunch of good uses for them to put money toward, but frankly I'm not sure R&D is the one that makes the best impact. I think if a non-profit is going to fund R&D they need to be really really smart, innovative and/or creative to make their money get the type of impact they could get on spending it in critical areas outside of R&D.

This changes depending on the field though. In some areas of the arts and humanities, non-profit funding is a huge and valuable source of funding.

But in tech/sci/eng? Not so much.
