In aviation people usually very thoroughly figure out what went wrong and why and only then suggest fixes. And the fixes are designed by the people who have access to the complete system.
I have seen various curriculum proposals, but the main problem is between the department of education and teaching unions. Teachers who can teach that curriculum are just not available. This threatens the teachers who clam up and whinge at the unions, who then moan at the department of education who back down and the cycle begins again. This is entirely self-destructive.

Remove the unions and hire ex industry people on a good salary with training and things will get better, but the current teaching standards across the board is just incompetent dross (bar about 5%). Teaching is not a profession at the moment. It is simply an easy career path for certain types of personality.

I include my wife in that statement as well and she would agree (she is an art teacher and there is very little space for her in society as a traditional creative person).

So summary: great idea, lacking any likelyhood of being executed unless they destroy the unions and hire better people.
Thanks. I agree. It was just done quickly to throw something out for testing. Definitely needs a redesign.

So you would argue Newegg should have folded to the patent trolls?

I'm not saying that's your stance, but I wouldn't worry about my employees' future without my company as much, since I am worrying about my employees' future in a world dominated by rent-seeking behaviors like patent trolls.

Maybe my employees see the world like I do. Maybe they don't. I can't wait for 100% unanimous approval before making decisions. I certainly plan to try and help them if I destroy the company that was paying them, but that's entirely up to me.

Dealing everyday with horrible code that is apparently 'fast' has got to be better than dealing with horrible code that is horribly slow. Management sometimes doesn't care about code quality, but it's easier to make a case for refactoring by saying improving performance will improve time users spend on the site and thus improve revenue.

Sci0031 – Cash Flow Statement – Where in the World is all that Money Going?
You're not necessarily keeping track of all the old values over time. Rather, the core idea is that you program in terms of abstractions that are explicit about time. That is, you write your program in terms of streams of events or signals.

You have signals and events, but you never ask about the value right now; instead, you take these two abstractions and combine them in different ways to get a reactive network. In a way, it's similar to dataflow programming or circuit design: you connect up "wires" into a network that can constantly push through data. Depending on how you write this network, you will need to remember different amounts of past data at runtime.

If you write your event/signal network carefully, you do not need to keep a history of too many prior values at runtime. This is one of the things modern FRP libraries really try to help you with: writing networks that are efficient. At least the ones I've tried are good at this--I haven't had many space problems in my programs so far.

In summary, this is a potential issue, and you may have to be a little careful in how you write your FRP code. However, modern frameworks try to make it easy to avoid these pitfalls, and there is no fundamental reason you can't use memory efficiently with this model.
We keep seeing people in the industry with a reckless contempt for reliability. Rather than the next gamified mobile social network for cat videos, why do they choose to build databases of all things? Do they just want to be popular among a bunch of founders of moribund startups who don't have large enough scale or good enough analytics to notice how their storage has permanently corrupted their data? Did they just not know that write(2) on a socket doesn't wait for a TCP ACK, and not ever tcpdump their protocol?

In a case like this, it seems the non-SA folk got fed up and ganged up on them. As it should be. No dominant force can remain dominant; if they piss off enough folk, either by being evil or just by owning all the things, said folk will band together and take them on.

Isn't it interesting how, caused by our inability to directly embed video onto websites, we are basically forced to reinvent video codecs in Javascript?

This basically means that on most mobile devices, instead of a hardware-accelerated decompressor, a slower, more CPU-consuming Javascript VM is in charge of video.

While technically impressive, I would much prefer the possibility of directly embedding (and controlling) real video.

Is this like that magic ink that patents are printed in that makes inventions something entirely different when you add "in planes" or "on the Internet" to them?
From a complete position of ignorance, I have never felt comfortable with these batteries in aeroplanes.

On of my wastes of time is RC modelling. These batteries have been used now for quite some time for power. What we RC people know is that while these batteries have great performance, it very easy to make one blow up if not handled correctly. Enough burned out sheds can testify to this. So, even if the engineers say they they can use them safely, I will always feel nervous of their use. Fine for things like RC models, laptops, phones, real cars even etc, but the plane use, to me, has a question mark against it.

OK, Im 100% sure engineers can make a great defence of their use, but there will always be a nagging doubt for me.
I've come to really dislike websites and services that don't tell you what they're about straight away.

New Online Backup Service is Launched by Novosoft Handy Backup
Novosoft, an international software development company and IT solutions provider began rolling out a new version of their Online Backup service. The updates include ultra-fast performance, initial backup seeding service, new web interface, and more.

Handy Backup is powerful, but simple and flexible platform for backup. From version to version Handy Backup acquires new capabilities, becoming more powerful tool to backup. Some recent useful innovation - strengthening of the program's ability to store data in the "cloud." Different versions of the program can back up the database MySQL, SQL Server, Exchange, and create a disk image of a single computer or over the network. The latest version of Handy Backup offers the opportunity to move from older versions of Windows to Windows 8, as well as plug-in for backup to WebDAV. The solution is a platform: many new features have been developed and are being developed by efforts of the user community. Also the ability to personalize the program for themselves is getting better and better.
For more information, feel welcome to visit the official Handy Backup brand page www.handybackup.net, https://plus.google.com/110815522739414748589 Handy Backup on Google+, Facebook, @Handy_Backup channel on Twitter, and Handy Backup on Google Groups.
I can add one more anecdote. My grandmother passed away before my first semester final exams in my first year. My parents didn't actually tell me until after my exams finished.

The thing is that she passed away in India. My grandmother would spend summers in Canada and winters in India. She passed away the same week a cousin married.

My hypothesis is that stressful things happen at the end of seasonal quarters. Final exams just happen to be one of those things. Flu season also happens to be December/January. Allergy season is around May/June.

I did a quick Google search but I can't find any information regarding death rate and monthly distribution. I would assume that it is evenly distributed but I wouldn't be surprised if the assumption was incorrect.

If it wasn't a suicide, I really hope someone clarifies the situation. It would be a pretty terrible thing (even more so) if everyone started to assume it was self inflicted when it wasn't.

Berlin, the promised (startup) land
Storing static files on a micro ec2 instance saves me money versus storing the images using s3. s3 charges by the GET requests and PUT requests. So if you're storing a lot of static files, like images, then you'll go through that free tier very quickly and start racking up the charges. But if you store those images on your ec2 instance and serve them with apache/http/whatever, then you don't pay for any of the requests, just the bandwidth. and if you have low traffic and optimize your images, its easy to stay within that free tier and pay absolutely nothing.
One of the organisations mentioned is Code Club[1], who do exactly that - they run small after school clubs, with volunteer programmers running them (and with a teacher to monitor the kids). One of the founders, Linda Sandvik, spoke at HN London a couple of months ago.

They're always looking for volunteers, so anyone here with some technical knowledge who would like to help kids learn computer engineering, give them a look!

Nope.

DESIGN your app, system, whatever properly. WITH performance in mind.

Then when you code it, you DON'T need to deeply optimize stuff with unreadable hacks, that may or may not even work. But you DO need to make smart decisions.

Almost every single piece of software i see that is slow, is slow because the underlying design is terrible. It's terrible because people are taught to "code now, optimize later", yet COMPLETELY discard having a decent design performance wise.

Here's the trick. Once it's coded, you can't redesign the whole damn thing without losing a monstrous amount of time. So you just try to optimize the parts you can and that's that. And it's slow.

Don't go optimize to gain 50ms right off the bat. But do write it properly so that it takes 1s if it can, and not 10min. Don't forget that there's a just middle in everything.

I think people have exaggerated feelings of insecurity about planes versus cars. Maybe it's because heavier-than-air flight just doesn't jive mentally, or maybe it's because you have very little personal control when flying. Either way, you carry these batteries on your person, in your coat pocket, in a bag, leave them in your study downstairs, hell, drive around in a big box made of them. Fisker Karmas were in the nasty habit of bursting into flames, but that was viewed as a one-off design flaw, not a crushing blow to 'batteries in cars' as a concept. I think the collective anxiety we feel towards planes, as a culture, shapes our views of these incidents too much. If your car was on fire on the highway you may not have handled it as well as the pilot in this scenario.
I can't imagine that the aerospace business is that different from the software industry or the automotive industry in that every product that gets delivered has known defects of unknown severity. It would surprise me if the planes didn't have at least a few hundred known issues -- a dozen of which may prove to be more serious than first anticipated.

Engineering reality may not match romantic expectation. Even for something as important as aeroplanes.

Last script I wrote - in about 20 lines of actual bash calling C programs which I know are well written, was performing the analysis of a 400meg file in about 15s.

File was in fs cache (you know, Linux has an actual decent fs cache, unlike some other kernels..). Anyway, I then realized 2 people coded the same script already, one using perl, one using python.

I sort of expected those would be slow, overengineered and what not after a quick look at the code. Then I decided I couldn't bad mouth stuff like this (even if I'm generally just telling this to myself) without giving it a chance.

python took 50s, perl took about 2 min (yeah given perl's performance with strings, I was rather surprised, this must have been pretty poorly done). Each of these programs had about 500 lines of code (!!!). Ridiculous. Unfortunately, that's seems to be the standard these days.

And I find this to be a perfect example, regardless of the language. No thinking => spend a long time writing a program with "nice classes" and stuff => its magnitudes slower than a non-optimized but properly designed program is.

Thinking about proper design, knowing how your language, runtime, libs, kernel works at least in the big lines => (much) quicker to write the program => decently fast, and you have more time to make it even faster now.

Ask HN: Alternatives to Kickstarter?
I've been working on several LED lighting projects for the last five years, and the latest is quite close to coming to fruition. It's a pretty awesome little gadget, fully open-hardware and open-source light with a 10W RGB+white LED and an arduino core that I'm targeting trying to sell for $70 each.

Unfortunately, the time it's taken me to design this has meant that I haven't had a full-time job in over a year. So, I don't really have the $40k or so it'd take to build 1000 first-run units.

As such, my first thought turns to kickstarter. But they charge 5% fees on the project, plus the 3.5% credit card fees, plus I may have to pay Philips patent royalties (probably not since these are prizes, not sales), plus I may have to do FCC certification tests (probably not since these are prizes, not sales), the list of "incidental" expenses goes on and on.

I think I might be able to do better if I could do something equivalent to kickstarter pre-orders on my own website, but how does one go about managing an eskrow of this kind? Is it possible, or is the only reason it works because kickstarter is there to manage it and make sure that the eskrow works properly? It may not sound like much, but that 5% overhead fee is a noticeable chunk of my revenue; enough that I have to remove components from the light to accommodate it.

If anyone is curious also, here is a link to the schematic:

And in Eve, this is even more feasible because, unlike an FPS or even MMO's like WoW, movement is generally slow and controlled. You don't have direct control over your ship; instead, you can only issue commands like 'head for this waypoint', 'orbit this point of interest', etcetera. This would, I think, greatly simplify server communication of movement and such, compared to direct user input where they could change their orientation much more suddenly.

I would say that logic is fudamental to math and cs. I disagree with mathematicians that claim that math is prior to logic.

Formal languages, turing machines, and computability are computing science, which we call computer science. Computing science may be part of math, but math is not fundamental to it. In other words, you need logic as a basis for those examples, but otherwise, they are not dependent on other mathematical knowledge.

I don't think sets are all that important in cs (but I disagree with mathematicians who try to base everything on set theory).
