"They want to send people to Mars"

I was actually thinking the other day about the people alive today who might be household names in 500 years - if Elon Musk achieves his goals for reaching Mars then his is probably the only name on that list.

And best of luck getting your job there. If I were younger I'd do the same thing. The mission tomorrow is I think the beginning of the privatization of space exploration.
Watching this live discussion is fascinating. There's a teacher who teaches 7 and 8 year olds asking how their love for Legos and video games could translate into a career in space exploration.

A career in space exploration. That's real today.

Just imagine how much more real it will be when those 7 and 8 year olds are all grown up.

Amazing!
Unless Microsoft will produce their own hardware for a Win8 tablet, I think we are going to see a whole slew of tablet models with varying (and sometimes dubious) build quality. Like it or not, the iPad is pretty well put-together - I think that the tablet manufacturers are really going to have to scramble to compete on the hardware front.

I actually think that Win8 has some potential as a tablet OS, although my experience with the developer preview on a PC was a little underwhelming.
Actual "glass whiteboards" are tremendously expensive - we're talking thousands of dollars. They seem really slick. Are you doing a DIY sort of thing, like this: http://www.ikeahackers.net/2012/01/not-expensive-glass-white...
Does a defendent have any recourse at all in such cases? If the government succeeds in shutting down a company without any finding of guilt, what's to stop them from continuing to use that strategy?
Most "office workers" have humanities degrees. I remember hearing that a degree in English was a useful default-major because "it's useful everywhere."

This isn't the case anymore, for a variety of reasons, but it certainly used to be true that graduating from college with a degree in anything gave you an advantage in the job market.

Well it suggests? That study had minimal controls for correlating factors, only alcohol and red meat, nothing about careers and lifestyles that correlate to coffee consumption. Less likely to die from "accidents" is an especially suspicious measurement.
Although I'm generally a market bear and have been saying we're in a bubble for months, even I'm having a hard time seeing how there isn't going to be an almighty pop today given the sheer amount of irrational exuberance over this.

My bet is FB closes somewhere between $55 and $65. Anyone else fancy making a prediction?

[ edit: stuck an upper limit on my prediction to make it more interesting :) ]
I think you have a virus or other kind of malware on your box.
Yeah but which one are you going to trust a chunk of your business revenue to?
The big feature of windows 8 that puts it onto tablets is that it runs on ARM. You would not want a current-model ARM to emulate an x86. People do that with DOSBox to run old DOS games (or even win3.1) but that's the extent of the speed capabilities.
Philanthropy. You can blow all the money in the world on it nearly anonymously and barely make a dent in all the misery, disease and suffering in the world - but even a noticeable dent would be enough to give you sound sleep and happiness for the rest of your life.

Not that I would know as I blow my excess income on fancy shoes and other frippery. But I hear it's nice.
Nice and all, but I clicked the link wondering why Institutional Review Boards were being tossed, seeing as how they're required by federal law to oversee ethics in research at publicly funded universities.
Yeah, I think the CDC does the random email thing. It seems really weird, but I guess I can only imagine how many @cdc.gov email addresses there are.
Maybe you could expand on that? Because it kind of sounds like you are suggesting that more women should be hired because they come cheaper. I imagine some women would take offence to suggesting the "gender wage gap" makes good business sense. I doubt that is what you meant but it sounds like it.
Excellent, a grey-area with no way to tell if you're over it

Are session cookies OK are under this law?
Interesting article -- but that assumes that you have both an RGBA source and an RGBA mask -- twice the RAM. When doing full screen compositing ram is a big deal.

If you are rendering solid color text, the source could be a constant. But if you are doing general composting the source needs to be another bitmap. You effectively use that mask as an RGB alpha channels.
I can really feel the irony here - one of the biggest gripes of Apple critics was the price of their products. It'll be interesting to see if things have turned around.
If they are running Windows on ARM, no x86 programs will work out of the box, they will need to be recompiled or recoded in some way.
It's my understanding that this was always the case- if the tablet is ARM-based, then it's not going to be able to run legacy x86 apps. Not to mention the UI problems. The good news is that it will be much easier for developers to port from x86 Win7 to ARM/x86 Win8 than it would be to make an iPad/Android version of their application.
Elicit anonymous feedback. It's hard (for me, at least) to complain face-to-face, especially to someone who writes your checks.
Exactly - without any data to train a model, most algorithmic and high-frequency strategies avoid IPOs.
In a way, this demonstrates quite well how the premium of buying a Mac makes sense for a lot of people. The extra few hundred dollars aren't too significant if it genuinely saves them time.
How is this any different than any other job, and why are we limiting a teacher's earning potential? If they're not well paid then they'll find ways to supplement their income.

If I'm well paid and satisfied with my current job then I'll make sure to get a good night sleep and be ready the next day to do a good job. If I'm unhappy or think I could be making more then I'll either do work on the side or spend more time working on my resume and interviewing for a better job. If I think my career doesn't have much potential then I'll really spend a lot of time outside of work trying to switch careers.

If you want teachers to do a good job, hire talented people and pay them accordingly. If you want a McDonald's like education system where a handful of chefs come up with bland but easily executable recipes then we can go down that path too. Just don't be surprised when your kids are switching careers from fry-vat guy to third grade teacher. And don't be surprised when the talented teachers see it as a stepping stone and get the heck out of there.

Left-handedness and Greater Risk of Death
I look forward to doing what I do on my desktop and more on a tablet, but the typing aspect isn't quite there yet. Why fear something like full Photoshop on the go, or a real suite of programming tools at your disposal?

If the typing issue was resolved (without adding a clunky, external keyboard) Then there it would effectively replace the laptop in my eyes.
This mission has been planned for a long, long time.

There have been several delays for more testing. At the end of the day, it seems that getting the software right was the biggest deal, but they've done many many simulation runs.

There's also a substantial on-orbit demonstration before Dragon is allowed anywhere near ISS.

There's still a lot that can go wrong, but almost all of it will result in a decision to de-orbit Dragon rather than going ahead with ISS docking.

Nonetheless, <fingers firmly crossed>
> The way to resolve this issue is to start out with greyscale antialiasing on the element.

no. The way to resolve this is to leave font rendering alone and hope for WebKit to fix the issue with 3dtransform so that at some point, it'll be able to use subpixel antialiasing everywhere.

And even if you insist on forcing grayscale on me, even though I find the subpixel one way, way more readable, then please use the official way to specify antialiasing (-webkit-font-smoothing) and don't rely on a bug by using transform3d.
This is the model which my Computing coursework bases around, you get something like 6 marks for code and 8 marks total for a "test plan"

I'm not a millionaire yet but the following really improved my lifestyle:

Pay someone to clean your house, your clothes weekly and fridge once every 3 months. It's socially acceptable even if you are middle class.

I'll echo the regular doctor checkups but do it also with your car. Less hassle in the long run.

Pay someone to handle your lawn (I live in Canada and snow removal is another thing I get done). You've just saved over an hour of time to spend on stuff you really enjoy.

Occasionally take a cab instead of taking the public transport just because you want to spend your time doing what you love.
The famous and misguided "iPad only has a few good apps" argument.

You know what you and others don't seem to understand. Your definition of good apps differs from my definition of good apps. Everyone likes and uses different apps for different reasons.

Ask HN:Your views on unique search engine problem
I am building an index of applications and would like to allow the users to search using a semi open text search. i.e some template the user has to complete words in.

Looking for some reference to existing solutions where the user will complete a sentence like:

for examples

I am looking fro an app that [verb] [noun]

or :

I am looking for an alternative to [app name]

and is being helped by the UI to tunnel the search to available options.

any ideas / pointers will be welcome.
I think if most wishes it to tank, its not because of envy, but rather because we all see how people lose control over their private data in the name of chilling out with friends on the cool website. This is extremely sweet candy that feels so good right now, but eventually you will throw up and have cavities.

If cinema projectors were bog standard then, there would have been no market for the Apple.
By the time it's anywhere near the station, it'll be moving at a pretty small speed relative to the ISS. The station's going to manually grab and pull in the spacecraft to avoid any automated docking "oopsies". Beyond those, the risk is pretty squarely in SpaceX's court.
Mandriva Linux Turned Over To The Community
That's not a release of data.
I'm not talking about blocking a website country-wide.

TTNET (biggest ISP in Turkey, founded and formerly owned by the government) gives you username for your DSL line, its usually something like phonenumber@ttnet (or yourname@ttnet1). If your username is like that, you connect with TTNET's DNS servers and your only limit is the sites that are blocked by courts.

But, if you're a school, they'll give you* a username like "schoolname@meb", when you connect with this there is a special black list (which includes word filters too) that can't be passed with anything but proxies. And, BTW, "proxy" is a blocked word.

For example, you can't -even- search for "porn" on Google. I'm not saying you'll need to search for porn on Google in school, just explaining how this black list works.

* A friend of mine explained it to me like this, he was a computer teacher in a government school. Now the system may be changed, I don't have clue, but the block is still there today.
Larger Input Strings for Text & CSV Format, Improved Smart Markers
The long awaited version of Aspose.Cells for .NET 7.2.1 has been released. It allows users to input strings larger than 32K for text and CSV formats. We have enhanced the shapes rendering module, specifically improving Excel-to-PDF conversion. We have also improved the Smart Markers feature so that Aspose.Cells for .NET now supports nested objects in Smart Markers. Moreover, we have made some enhancements regarding PivotTables and the internal Worksheet-to-Image modules and fixed some other issues. We have also enhanced the Formula Calculation Engine and fixed a few of its issues. This release includes few enhanced features and plenty of bug fixes as listed below

•	Shapes’ lines are correctly filed after converting to PDF
•	Macro disappearance is fixed after saving an XLSM file to XLS format
•	List box options overlap one another is fixed
•	Aspose.Cells corrupting XLSM file after calling the Workbook.Save() method
•	The component destroys properties of the workbook XML’s CalcPr node
•	You want to put a string longer than 32K
•	Smart Markers syntax for column index

Coming from the UK, I'm always amazed at how important health insurance is in the US, and what a broad range of quality of healthcare there is. Our company provide a free, private healthcare (BUPA), but I've never felt the need to use it.

Recently, I had surgery for an ACL tear. Unfortunately, for some reason, it later went septic. The day the consultant found it was septic he rushed me into surgery that afternoon and I spent the next 6 nights on IV antibiotics, followed by a course of oral antibiotics. At no point did I have to worry about how much all this cost - and I didn't ring BUPA just because I couldn't be bothered and it was all perfectly satisfactory care.

When I was a kid I had extremely bad asthma. A new respirator type device had just been invented and I was one of the first in the North West to have one. These things cost thousands of pounds at the time and there's no way my parents would have been able to afford it, but they got it loaned to them completely free. It quite possibly saved my life.

I used to think how lucky I was that I wasn't born in some third world country where I would probably not have survived, but recently I've started to be glad I wasn't born in the US.

You guys really need to sort this out.
There will also be live streaming on the SpaceX website. They've invested in better video streaming infrastructure since the COTS1 launch, so hopefully this will stand up to demand. Everything worked well during the static-fire test a couple of weeks ago -- which is obviously less popular than the actual launch, but still drew in a fair few viewers.
Hahaha, that was actually what I realized.. only if it was a mistake to buy would my order get filled. Or a very random fluke resulting in a fill before it jumps to ~60+

I don't know where you've been the last 10 years.

The iPod was the first wave of Apple devices where the price was actually cheaper than the competition. Then that trend continued with the MacBook Airs and iPads. Even the iMacs/MacBooks are very competitive.
You definitely shouldn't confuse "I haven't yet figured out how to change X" with "X is inevitable".

Three things that weaken those feelings of envy for me:

One is treating them as something my brain does. Sort of like one does with a transient ringing in one's ears or a twitchy muscle or a mild cold. I think, "Oh, that thing again," and wait for it to pass.

The second is appreciating what I have more. If you focus all the time on what you don't have, it's easy to miss all the things you do have.

The third is better understanding others. Spend some time really looking at the people you think you envy. Rich people are often miserable bastards. Even the ones who aren't miserable have made sacrifices I'm not interested in making, or are fundamentally handicapped in a way that I'm glad not to be. Nothing comes without a price.
PayPal without a doubt.

You hear horror stories about both (for Google e.g. http://news.ycombinator.com/item?id=2483609 , http://ask.metafilter.com/178634/How-to-get-Google-Checkout-...) . Granted- more about PayPal, but they handle a lot more payments for a lot more people. What nearly all these horror stories have in common is that they're gathering pre-payments/donations for some even in the future. You rarely hear it from those shipping physical or digital products.

Generally they're pretty good. They've got low fees, they work worldwide, no need for a PayPal account to pay, and you get the money quickly.

They're widely trusted by a lot of consumers as their refund policy is very buyer friendly.

On one of my sites I offer PayPal vs Fastspring as a payment choice, and well over 90% choose PayPal.
Yes but, in the case of android, the assembly work is
rather trivial if they wanted to offer a standard
android rom.

Most of the complexity lies in the gui elements added by the
manufacturers (TouchWiz, HTC Sense, etc) in an attempt to
differentiate themselves from the rest and foster brand
loyalty.

In any case, I don't think the software customization
cost per unit in android phones it's anywhere near those
MS license costs.
So how well does Linux support that setup? Or you're using OSX at Google?
The standardization of iOS devices is what makes them so easy to use and develop for. Microsoft has done a good job of making Windows behave in a standard manner on diverse hardware configurations on desktops and laptops, so we can hope that WM8 will be equally standardized across different hardware. That would at least give them an advantage over android, and if they don't drop hardware support at certain versions they might be able to take over slowly when the cost of WM8 tablets drop below the cost of an iPad.
Space Apps Challenge Results
It only used the word "free" for Amazon's use of Android, which is factually accurate. It said that Apple gives iOS away, which again is an accurate statement. It doesn't seem disingenuous to me; in fact the wording implies that Apple is indeed "giving away" real value.

I recently reviewed a large number of resumes from CS majors from a wide variety of universities. They were collected through career fairs sort of things.

Nearly all of them were crap. There was a constant and persistent inability to demonstrate what they had to offer my company. There was a massive focus on class projects and a complete "meh" in terms of work history.

Now, some of these people might have been excellent hires. But they could not demonstrate their aptitude. The people I did contact did have a differentiating factor: it was that they did something... almost anything... out of the ordinary in their life and put it on their resume.

People I contacted included a YC company intern, someone who liked Haskell, and someone who had gone from total programming novice to real-time operating system coder in 4 years.

Danger signs included gaps in employment (why does $applicant's resume stop in 2008?), inability to spell correctly, and lack of knowledge of the tech world.

It's not hard to apply Sturgeon's law and lift yourself out of the drek that I saw. If you want help resume building, feel free to email me. I can help you tune your resume to demonstrate your awesome (at least to another CS geek! :-) I can't say anything about what other fields look for ).

Oh, I agree! A tall cup of Colombian with a shot of hazelnut is absolutely delicious. I can't drink it totally dark though, there has to be some type of creamer or sugar in it where I can enjoy it properly... but then there's the amount of calories in doing so.. but I digress :)
The problem is deeper than just money. There's a branding issue. There's an app issue. There's a quality issue.

You need to magically fix all three of these, plus address the pricing difficulties. Good luck.
