When one is basically "stumped", walking away is often the most effective, efficient means to make progress. The mind continues to work on it in the background while you do other things and then you can come back to it later from a fresh perspective, less frustrated and so on. I told this to my son once when he was playing a computer game. I walked past and he was basically spitting nails in frustration. I told him to walk away for a time. He did and when he went back later he was able to solve it, first try.

If the task is more physical, a physical break can make it more do-able. I had to hook up my own washer and dryer by myself once and reached a point where I was very frustrated and couldn't make something work. Napping allowed me to come back to the task and promptly put together what I had previously struggled with fruitlessly for an hour. I had simply been physically tired.

So I can see that switching between two tasks could be a very effective approach, and not "procrastination" at all.

You are drawing an invalid analogy between cryptography and filtering. The only reason cryptography works with open algorithms is that the keys can be kept secret. To a very large extent in filtering the specific algorithms are as analogous to cryptographic keys as they are to the other parts of crypto-systems. That is, filtering algorithms are like very primitive cryptography where there was no separation between the system and the keys.

You can ignore 90% of the machine learning literature, treat the whole thing as a craft rather than a science and use OPAL/PA-II or an averaged perceptron (which are closely related with proven 50s and 60s machine learning technology, but are very well-understood these days), with regularization.

It doesn't necessarily take a PhD to realize that, but fortunately (for me) you'll need a PhD to convincingly sell that point to non-machine learning people.

This is actually an interesting site, but the way you're posting here is going to get you flagged off for gratuitous self-promotion.

If you provide some more context on your goals for the site, your experience building it, or what sort of feedback you'd like, I think you'll find the community much more responsive.
I'll second this. If you're looking for a cheap, light notebook with mid-range features, look elsewhere; however, if you want a fast, portable machine for development/design, I don't know of anything better. I've had one for about a year (typing on it now), and it's probably the best development laptop I've ever used (maybe even best development machine, period).

The only drawbacks I've seen are the price (it's quite expensive) and Sony isn't very good about keeping their drivers up-to-date, so anything custom/customized in the machine (like the graphics card) is kind of annoying to get new drivers for.

Offline Gmail is cool.

Ask HN: Are we ever going to run out of space?
Obviously we have data centers that are ridiculously huge and can store crazy amounts of information. It's kind of like all those major things that may not happen tomorrow but will probably happen soon.

On to my questions, if millions of people everyday are pouring information into the web, how does the web get rid of information? And at what point will we have a space problem because data has to be stored somewhere. It might be a dumb question because obviously we are good for now, but with more content intensive startups and companies form what does the future look like? Just curious what you guys think.
The license change took away the license for OSes (e.g. linux distributions) to distribute the Oracle JDK (which includes the Java Runtime Environment) as part of their distribution.

This means linux distributions can no longer supply the official Oracle JDK as "native" packages. It is still available for free (monetarily), but only as a direct download from the Oracle site.

The IcedTea Wikipedia entry http://en.wikipedia.org/wiki/IcedTea#History has a summary list of what proprietary binary bits are in the Oracle JDK. It has a footnote reference to http://en.wikipedia.org/wiki/Java_Class_Library#Licensing which is more definitive.

Impact?

* Ubuntu (and, I presume, all the others) has already deprecated or removed the Oracle JDK, thus little or no impact.

* The Oracle JDK is still available, so from that POV it has little impact. However, the Oracle JDK is now outside the distribution packaging system, so if you download the Oracle JDK and then try to install a package that depends on having a JDK/JRE, the packaging system (e.g. apt/yum) will not know that you have the Oracle JDK installed and will install OpenJDK. This will result in confusion and conflicts (at least, it did for me ;-).

* Oracle says it is moving to being based on the OpenJDK itself, so the dichotomy should resolve itself. http://www.oracle.com/technetwork/java/javase/community/open...

"Oracle's commercial JDK releases will be built from the open-source code, for the most part. Since there's some encumbered code in the JDK, Oracle will continue to use that code in commercial releases until it is replaced by fully-functional open-source alternatives. To learn more about development and deployment support options, visit the Java Support site."

* Licensees of Oracle SE will still be able to distribute the Oracle JDK: http://www.oracle.com/technetwork/java/javase/overview/licen...

Suggest HN: earn karma for each flag after your own?
There's lots of garbage on the /newest page with no incentive to police it. A new post requires something like 5 flags within an hour to be flagged into non-existence.

Since flagging away bad content is as important for overall quality as upvoting good content, I think flaggers should receive a karma point for each time the post is flagged after they've done it.

While I'm here, maybe a few more people can chip in on the new page, being more liberal with upvotes than you would be on the homepage, and flagging some of the junk. Rad.

Thank you, this post was good and informative. Nevertheless I think you missed his main point and concentrated on something that was merely incidental to it.

Yes, spam fighting is hard. Yes, it's probably easier with huge centralized installations (he actually observed that at this point the centralization offers advantages over the decentralized model.) But his main point was not about spam nor even about e-mail in general. His point was that it is worth putting the additional effort into making decentralized systems work. This is definitely not what Google are doing.

I'll wait for the cryptographers to weigh in; but, it's in Javascript.. already a language that's going to be hard to Do It Right in. (The first third of the code is a BigInteger implementation)

But then then says it's "New BSD license"[6] when it should be GPL[7].

I didn't start this comment sound negative. But, I think a few things are important:

* Credit authors.

* Respect their licenses.

* Put a big fucking notice on top of your slick webpage: "FOR DEMONSTRATION PURPOSES ONLY-- NOT REAL CRYPTO"

I just looked at the link to Samsung 9 series and the googled for the Sony Viao Z series.

The Samsung 9 in the link is 1600EUR. I checked the German Apple site. The top end Air is 1499EUR. The low end 13" with a 128GB SSD like in the link is 1249EUR.

I looked up the Viao Z series on the Sony German site and this is a bit confusing. It says that it starts at 1754EUR which seems like a really good deal. But at the bottom where there are preconfigured models with more detailed specs that you can compare, it really starts at 2299EUR (so what are you getting for 1754EUR?).

The Air is the cheapest option???

I haven't tried Linux on any Sony devices yet, how is the driver support? I tend to buy Lenovo only since I'm always confident that full driver and wireless support will be there always. The Vaio Z is very enticing, but with similar offerings from Lenovo like the X220, I'm tending towards the familiar.

Not his test suite, his test environment.
In May I was thinking about the X220, finally I've decided for a MacBook Pro (No new Airs at that moment).
My decision was mainly because I prefer the Mac OS to Windows.

Of course I was going to install Linux on the Levono and Wipe Windows, but now I have OS X with my Laptop and Linux with my Desktop.
Disagree. Everyone in my office got VAIO Z's. They were great machines for about 9 months, then started having SSD, overheating, and graphics problems. I used to be a huge fan of the VAIO, but not any more.
I actually switched from 2010 Air to X220 after the 2011 Airs came out.

Needed a Windows machine and did not like where Lion was going - with 2011 MBA I would have no choice but to run Lion and Windows with half baked support (AHCI, other minor annoyances)

The X220 fits the bill -

1) Display is good - it's IPS panel with good viewing angles and great brightness (Make sure you opt for Premium HD display)

2) Battery life is great - 6-7 hrs for regular use is no big deal at all with the normal battery. Go with 9 cell for little extra thickness and you are talking 9 hrs.

3) It is fast even with the 7200RPM HDD - resume from sleep is fastest I've seen for a Windows laptop with regular HDD and pre desktop fingerprint authentication saves you more time.

4) Legendary Thinkpad keyboard - love it!

5) Fast regular voltage i5/i7 CPUs - not undervolted ones.

6) Does not get noisy or hot even under full load - the i7 models throttle a bit more but are still great.

7) Can have 8GB RAM - big deal for me as I run VMs. Not an option with the Air.

The only issue really is the tiny trackpad. It gets the job done but is nowhere near the nice big glassy one on the Air. If you were into Linux X220 runs Ubuntu 11.04 great out of box - added benefit.
German Police on Video Surveillance Effectiveness (Wikileaks cable)
What concerns me about RN policies is the immoderacy with which they're often pursued, not the idea itself. It's actually (gasp!) a good idea at root. I have no problem with allowing pseudonyms and role accounts-- I think G+ and Facebook should-- but Google is right not to want profiles with names like Fuckhead89 and MiKeY ~:~ j0n3S on the service.

Giving less leniency (in terms of the decision whether to can spammers) to non-real-name accounts makes sense. Stopping impersonation is obviously the right thing to do. Preemptively treating accounts as negative-value accounts simply because they look* pseudonymous is the wrong thing to do.

What I think needed to be said in the boardroom conversations is that the damage done by deleting a good (even pseudonymous) profile is about 100 times that done by allowing a bad profile. Bad profiles (spammers, trolls) will ruin a site, but they're only dangerous if numerous enough to establish a critical mass. The cost of ripping out a good, potentially pseudonymous profile, is a nasty blog post that makes the rounds on the internet.

There's a lot of interesting grey area between surrendering everything to Google and rolling your own mail server. I unplugged from Google this month but I'd still rather pay a little money to fastmail.fm, for instance, than fight spam myself.

The net isn't the wild west anymore but it doesn't have to be a sterile walled garden either.
I own a Lenovo X220, bought before the Air refresh.

Similar weight as the Air but much thicker. Little more powerful CPU to which I added 8GB ram and a 240GB OCZ Vertex 3 SSD.

12-13" IPS display, is the crappiest IPS I ever saw, still better than a TN though.

Battery life is around 5h, OK I guess.

Keyboard is great but touchpad is horrible. Mac os x is not an option, but Win 7 runs pretty great on it.
