Unlike what has been done in previous work, Hanenberg decided not to use existing programming languages and IDEs in his experiment because he worried that subjects’ familiarity with the tooling would influence the results, in particular if his subjects knew only the dynamic or only the static version used in the study. Therefore, he developed a new object-oriented programming language “Purity” (with some similarities to Smalltalk, Ruby and Java) and a corresponding IDE (class browser, test browser and console). Actually, he developed two versions of Purity: one with static types, the other one with a dynamic type system. The two versions were identical in all other aspects. ...and the great debate continues....

Upgrading to the new Windows 8 operating system is not nearly as complicated as it looks, despite Microsoft's sometimes muddled marketing. Getting used to using it is a different story. Here are the basics for regular, non-techy Windows users curious about getting started with Windows 8. The real nerds have been playing with it for monts. Everyone else just started looking for Start.

The videogame console as we’ve always known it actually died a few years ago. It keeled over somewhere around the time that Microsoft redesigned the Xbox 360’s user interface so you had to tab through “Bing,” “Home,” “Social” and “Video” before you got to the tab marked “Games.” Ever since, the big three makers have been bending over backward to show that their boxes aren’t just dumb game players but connected everything-machines that play more Hulu than Halo. Consoles used to do everything best, but those strengths are now being wiped away.

Even 10 years ago, mapping software was still incredibly expensive and difficult to use. Maps cost tens of thousands of dollars to make, and to share them, you had to print and distribute hard-copy versions. That’s all changing very quickly. The maps of today are mobile, intuitive and fueled by a rapidly expanding catalogue of data to which laypeople — sometimes unknowingly — contribute. What happens when old-school cartography meets new-school technology?

In today's era of advanced persistent threats, spear-phishing attacks, social engineering campaigns, and drive-by attacks, are endpoint security solutions performing well enough? The NSS Labs report suggests not. "Most vendors lack adequate protection against exploits," according to the report. As a result, "based on market share, between 65% and 75% of the world is poorly protected, and 75% to 85% in North America is poorly protected." It is an army bred for a single purpose: to destroy the world of men. They will be here by nightfall.

This is a fairly surprising result. Other comparisons I've seen in the past showed a much smaller gap between the most and least effective products; and placed MSE only slightly behind the most effective AV scanners. Even there the ones that performed better than MSE by an amount that looked better than just statistical noise were all much more intrusive.
Has the landscape changed that much over the last few years; or was the design of this test just very Kapersky friendly?
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

That's a good question. The article includes a link to the study itself. I only scanned over the study, so won't comment on its validity, but they did document the testing methodology, including the specific vulnerabilities tested.
My layman's take: Kaspersky, Norton and Mcafee do this as a core business. They seem to take different approaches and, as a result, excel in different versions of the tests.
The threat environment does changes quickly and constantly. It could be that Microsoft is simply not keeping up, or got distracted by the Windows 8 launch (which they probably need to ship a new product for).

Desktop Windows has tiny buttons, menus and controls that are generally too small for finger manipulation, and TileWorld is filled with gestures that make sense only on touch screens. If you install Windows 8, you’ll have to learn both environments, like it or not; you can’t live in just one environment or the other. So the question arises: how are you supposed to operate TileWorld if you have a nontouch computer? Answer: There are mouse and keyboard equivalents for the touch gestures.

Hi all,
I wanted to share a tool I recently developed. Over the years I've gotten so sick of manually typing concatenated strings and / or Stingbuilder objects. Last week I decided I'd had enough. I created a tool that automatically generates concatenated strings and Stringbuilder code:
www.buildmystring.com
Enjoy. I'd appreciate any feedback as well.

So, let me get this right. You created an account, you post a single message, pushing a link to your site, to effectively advertise something you have created. Regardless whether it is free or not, that is spam in my books!
If you had been smart, you should have created an article, talking all about why you decided to come with mystringbuilder, what its pro's and con's are, what performance metrics there are and also showing some sample code on how it all works.

I think that's a little strong. At least it's free. It would have been better if he'd posted in the free tool's forum.

If you're a web developer, you've probably had to make a user account system. The most important aspect of a user account system is how user passwords are protected. User account databases are hacked frequently, so you absolutely must do something to protect your users' passwords if your website is ever breached. The best way to protect passwords is to employ salted password hashing. This page will explain how to do it properly.

Great article, agreed. But he doesn't cover when to hash in a web app.
If I enter a password on a webpage, shouldn't I hash the password before I send it to the server?
If I retrieve the salt into the webpage from the server first and then hash the password before sending to the server, doesn't that have security implications too?

If the hash would be calculated at the client, then the salt is needed at the client. When logging in, the user name has to be sent to the server, and then the salt would be sent back for that user, regardless of the password. So anybody would be able to retrieve salts, which would render them useless.

Exactly my point. So, you'd need to do something else between client and server to secure the account id and password.

Ofcourse, you need SSL to secure the password transfer. But even with SSL it wouldn't be a good idea hashing at the client because anybody could get anybody else's salt.

Salts are not meant to be secret. That's the beauty of salts. They are only used to prevent rainbow attacks and are not there for additional secrecy (as the article also mentions by the way). So it's no problem to publish the salt of every user account.

Ah yes, you are most definitely right, thanks for correcting me!

The following is the response I received from the article's author, after asking the same question via email:
----- Start Email Response -----
Hi,
Here's a copy-pasted email I just sent someone who asked a related question:
------
Even if you are hashing the password on the client side, you still have
to hash on the server. Because if you just hash in the browser, then the
hash "becomes" the password in the sense that the hash value is all an
attacker needs to get in to someone's account. If a bad guy hacks into
the database storing all of these values, then he'll have immediate
access to every account.
So regardless of what you do in the browser, you still need to hash on
the server.
[ the original sender was worried that looking up the salts would let an
attacker test if usernames are valid without knowing the password ]
Anyway, if you do hash on the client side too, you're right that you
really don't want to let an attacker test if usernames are valid. Since
you're still hashing on the server with a random per-user salt, it's OK
to sacrifice randomness for the client-side salts. I recommend combining...
1. The username.
2. A website-specific string (e.g. the domain name).
...to make the client-side salt. It's not guaranteed to be unique (e.g.
domain changes ownership), but it's very likely to be. It's good enough.
Another thing to consider is that not all users have JavaScript enabled
in their browser (I don't), so whatever you do, the system should fall
back to emulating the JavaScript hashing on the server if the user isn't
running scripts in their browser.
-----
I'll add this to the FAQ or to the main article since it's very
important to get right!
Thanks!

Yeah, I had already sent an email to them. It's the one he copy-pasted to you.
